Description

  The present invention relates to a window sealing device particularly suitable for vehicles and a seal strip constituting the window sealing device.

  As a window provided in a vehicle such as an automobile, there is typically a glass window that moves up and down (typically moves up and down) in a door attached to a side surface of a vehicle body. A sealing device mounted along a groove formed in the door frame includes a long sealing strip (typically a glass run, a glass run, etc.) formed from an elastic polymer material such as rubber or thermoplastic elastomer. Guide strips, also called channels, run channels, guide members, etc.) are often used. The main purpose of the seal strip is as follows: (1) The seal portion of the seal strip is brought into elastic contact with the outer peripheral surface of the window plate by elastic pressing force to seal between the window plate and the door frame. Intrusion into the vehicle and (2) When the window plate moves, the window plate is guided to a predetermined position.

  The window pane of the window is connected to an elevating mechanism (typically, two types of X arm mechanism and cable type mechanism are frequently used) where the lower edge of the window plate is provided inside the door, The window plate moves up and down in the door frame by the operation of the lifting mechanism. The elevating mechanism is connected to a drive source (typically, an electric motor) different from an engine or the like for running the vehicle, and the elevating mechanism operates as the drive source is driven. The drive source is operated by operating a selection switch for raising or lowering a selection switch (typically, a selection switch provided on a door inner trim or armrest inside the vehicle) of the door.

Maintaining good sealing performance between the window plate and the door frame, which is one of the objects of the sealing device described above, can be achieved by increasing the pressing force of the seal portion that contacts the surface of the window plate. .
On the other hand, the greater the pressing force of the seal portion, the greater the frictional force between the moving window plate and the seal portion, and the sliding resistance when the window plate moves increases. Thereby, in order to move the window plate, a large driving force and a sturdy and large window plate moving mechanism are required. Further, when the sliding resistance when the window plate moves increases, wear of the seal portion increases and the life of the seal portion is shortened. Further, when the window plate moves, a rubbing sound (abnormal noise) between the window plate and the seal portion may be generated, which causes problems such as discomfort to the passenger.
In general, assuming that the total load when the window plate moves up and down, in particular, ascending, is 100, the load caused by sliding between the seal portion of the fixed seal strip such as the glass run channel and the moving window plate is 30. It is said that the load due to the weight of the window plate is about 28, which is the largest at the front and back.

  From the viewpoint of reducing the above-described sliding resistance, for example, in Patent Document 1, a layer of a low friction material having a smaller friction coefficient than the weather strip body is integrated with the surface of the lip portion that contacts the surface of the window plate that moves up and down. An invention is described in which sliding resistance is reduced by mechanical molding. Further, in Patent Document 2, a plurality of ridges are formed along the longitudinal direction on the surface of the seal lip that contacts the surface of the window plate that moves up and down to reduce the contact area with the surface of the window plate. An invention for reducing dynamic resistance is described. Patent Document 3 describes an invention that reduces sliding resistance between a window glass that moves up and down and a rubber thin film by forming a hollow chamber in a glass run.

JP 05-330345 A JP 2005-247164 A JP 05-270277 A

  However, in both Patent Document 1 and Patent Document 2, the seal strip (weather strip) is used in contact with the surface of the window plate, and the seal between the window plate and the door frame can be satisfactorily achieved. Since it is required, it is necessary to make contact with the surface of the window plate while maintaining a predetermined contact pressing force. Therefore, it is not always sufficient from the viewpoint of satisfying both maintenance of sealing performance and reduction of sliding resistance.

Further, in the invention of Patent Document 3 (particularly, the description after paragraph [0035] of the third embodiment), the first and second hollow chambers 14 and 16 of the glass run are rubber when the window glass is opened and closed. The thin films 13a and 15a are separated from the surface of the window glass (this state is a natural state (equilibrium state in the specification)). With the window glass closed, air is supplied into the first and second hollow chambers 14 and 16 to bring the first and second hollow chambers 14 and 16 into a positive pressure state. There is a description that it is in a state of being crimped to the window glass.
However, in the invention of Patent Document 3, the problems described below have not been solved, and there is room for further improvement in order to provide practical use.

  When the vehicle travels with the window glass half-opened (with the window glass moved from open to closed or moved from closed to open), the first and second hollow chambers 14 and 16 return to an equilibrium state, and the rubber Since the thin films 13a and 15a are in a state of being separated from the window glass, the window glass cannot be maintained at a proper desirable position (particularly in a direction orthogonal to the window glass surface). When the vehicle travels in this state, when lateral vibration occurs in the traveling vehicle, the window glass sways violently relative to the frame due to the inertial force of the window glass, and the glass run fitted in the protective frame It collides with the side wall and an abnormal noise such as a collision sound is generated.

  The present invention was created to solve the above problems, and is sufficient when the movement of the window plate is stopped (typically when the window plate is closed and half-opened). Should the sliding resistance be eliminated when the sealing property is maintained and the window plate moves at least ascending (typically when the window plate changes from the open state to the closed state and from the closed state to the open state)? It is an object of the present invention to provide a novel sealing device that can be reduced or a sealing strip used to construct the sealing device.

In order to achieve the above object, the present invention provides a sealing device mounted on a door frame of a vehicle.
That is, the window sealing device of the present invention is formed integrally with a door body of a vehicle door having a window and the door body as described in claim 1, and between the upper edge of the door body. A rigid door frame having a predetermined-shaped window opening therein and a continuous groove having a predetermined width therein, a window plate that moves up and down along the groove of the door frame to open and close the window, and the door frame A long sealing strip that is mounted along the groove of the window plate and is fixed to the door frame, seals between an outer periphery of the window plate and the door frame, and guides the window plate moving up and down; and the door A vehicle door window having a window plate elevating mechanism connected to an outer peripheral edge of the window plate and moving the window plate up and down; and a drive source for driving the window plate elevating mechanism. It is a sealing device.
The seal strip is disposed at a position facing the outer peripheral edge of the window plate when mounted in at least one groove of the door frame arranged in parallel with the raising / lowering direction of the window plate, A side strip extending from at least one of the vehicle inner end and the vehicle outer end in the width direction of the bottom strip toward the center of the window opening;
At least one of the side strip and the bottom strip is a tubular seal portion having an internal space that is closed by an elastically deformable hollow wall and is filled with gas at a position facing the outer peripheral edge of the window plate. Are formed in the longitudinal direction.
The tubular seal portion is capable of expanding and contracting the outer shape and the volume of the inner space corresponding to the increase and decrease of the atmospheric pressure of the inner space, and when the outer shape and the volume are expanded, the outer surface of the tubular seal portion is the window plate. The outer peripheral edge of the window plate is in contact with the outer peripheral edge while maintaining a predetermined pressing force per predetermined length, and when it is reduced, it is not in contact with the outer peripheral edge of the window plate or the pressing force is reduced. Can be contacted.
The tubular seal portion reduces the external shape of the tubular seal portion and the volume of the internal space by sucking the gas in the internal space of the tubular seal portion and reducing the atmospheric pressure at least during the upward movement of the window plate, When the window plate is stopped, gas is allowed to flow into the internal space and the atmospheric pressure is increased so that the outer shape of the tubular seal portion and the volume of the internal space can be expanded. .
When the window plate lifting mechanism is inactive and the window plate is stopped, the tubular seal portion is within a longitudinal range where the outer peripheral edge of the window plate does not exist in the seal strip. Located in the first position.
In a longitudinal range where the outer peripheral edge of the window plate is present in the seal strip, the tubular seal portion is in contact with the outer peripheral edge of the window plate, so that the window plate is closer to the first position than the first position. It is displaced to a second position away from the opening / closing movement path and is contacted with a predetermined pressing force applied to the outer peripheral edge of the window plate to seal between the window plate and the door frame,
When at least the window plate moves upward by the operation of the window plate elevating mechanism, the gas pressure is sucked from the internal space of the tubular seal portion by the operation of the atmospheric pressure adjusting mechanism to reduce the atmospheric pressure in the internal space. (1) The tubular seal portion is displaced over the entire length to a third position that is further away from the opening / closing movement path of the window plate than the second position so as to be in a non-contact state with the outer peripheral edge of the window plate. Or (2) the pressing force per predetermined length of the tubular seal portion against the outer periphery of the window plate is within the longitudinal range where the outer periphery of the window plate exists in the seal strip. The contact is made in a state where the pressing force at the second position is reduced.

  In the window sealing apparatus of the present invention having such a configuration, at least one of the side strip and the bottom strip is closed by a hollow wall that is elastically deformable at a position facing the outer peripheral edge of the window plate, and the inside is filled with gas. A tubular seal portion having an inner space is formed in the longitudinal direction. The tubular seal portion can reduce the atmospheric pressure of the internal space when the window plate moves upward at least (the internal space is in a negative pressure state), and can increase the atmospheric pressure of the internal space when the window plate is stopped. It is connected to a pressure regulation mechanism that can. When the air pressure in the internal space is reduced, the outer shape of the tubular seal portion and the volume of the internal space are reduced, and the outer surface of the tubular seal portion is separated from the outer peripheral edge of the window plate or is in non-contact state or in contact The pressing force of the tubular seal portion against the outer peripheral edge of the window plate is reduced. On the other hand, when the atmospheric pressure in the internal space increases, the outer shape of the tubular seal portion and the volume of the internal space expand, and the outer surface of the tubular seal portion contacts the outer peripheral edge of the window plate with a predetermined pressing force.

  As described above, in the window sealing device of the present invention, by expanding and reducing the outer shape of the tubular seal portion and the volume of the internal space, the open / close window plate is stopped (typically, the window plate is closed). When the outer surface of the tubular seal portion is in contact with the outer peripheral edge of the opening / closing window plate, a predetermined sealing performance can be maintained between the door frame and the window plate. On the other hand, when the window plate moves up at least (typically, when the window plate changes from the open state to the closed state), the tubular seal portion is retracted to a position away from the outer peripheral edge of the window plate. And the tubular seal portion (“dynamic coefficient of friction of the tubular seal portion (μ)” × “load applied to the window plate of the tubular seal portion (P)”), the load (P) is eliminated (becomes zero). ) Or decrease. As a result, the sliding resistance (resistance associated with the frictional force) can be substantially eliminated or reduced as compared with the prior art. Furthermore, at least one of the following (1) to (4) is possible. (1) The wear of the tubular seal portion that is in contact with the window plate is reduced or the wear of the tubular seal portion is reduced in another form of the seal device (a form that reduces the atmospheric pressure in the internal space even when the window plate is moved downward). Since this is eliminated, the lifetime of the tubular seal portion can be extended. (2) When the window plate is moved, the driving force (especially, the load of the electric motor in the case of electric operation) when moving up the window plate is smaller than in the prior art. Therefore, the moving mechanism (window regulator mechanism) for moving the window plate can be reduced in size, simplified and reduced in weight. (3) During the movement of the window plate in a state where the tubular seal portion is separated, no rubbing sound is generated between the window plate and the tubular seal portion. (4) Since the tubular seal portion acts as a gas cushion (buffer), no collision sound with the door frame or the like is generated even if the window plate is suddenly displaced in the lateral direction of the vehicle.

According to a second aspect of the present invention, in the window sealing device according to the first aspect, the tubular seal portion is used when the window plate moves up and down (that is, when the window plate moves up and down). By sucking the gas in the internal space of the tubular seal portion and reducing the atmospheric pressure, the external shape of the tubular seal portion and the volume of the internal space are reduced, and the gas flows into the internal space when the window plate is stopped. At the same time, the pressure is increased and the air pressure is connected to a pressure adjusting mechanism capable of expanding the outer shape of the tubular seal portion and the volume of the internal space. When the window plate moves (that is, ascending and descending) by the operation of the window plate elevating mechanism, the gas is sucked from the internal space of the tubular seal portion by the operation of the atmospheric pressure adjusting mechanism. (1) The tubular seal portion is displaced over the entire length to a third position further away from the opening / closing movement path of the window plate than the second position. Or (2) a predetermined length of the tubular seal portion with respect to the outer peripheral edge of the window plate within a longitudinal range in which the outer peripheral edge of the window plate exists in the seal strip. It is made to contact in the state which reduced the pressing force of the contact with the pressing force in said 2nd position.
According to such a configuration, the tubular seal portion is connected to a pressure adjusting mechanism that can reduce the pressure in the internal space when the window plate is moved up and down, and can increase the pressure in the internal space when the window plate is stopped.

At this time, the tubular seal portion 130 is provided over the entire length of the seal strip so that the internal cavity or hollow portion is continuous from the center pillar side vertical side frame 61 to the front pillar side vertical side frame 63 via the upper side frame 50. It is preferred that
In the sealing device 3 according to the present embodiment, the tubular seal portion 130 is provided over the entire length of the seal strip assembly 100. As shown in FIG. 1, connecting tubes 136 and 136, which will be described later, are airtightly connected to lower ends of the center pillar side seal strip 102 and the front pillar side seal strip 106, respectively.

  Each of the center pillar side, upper side and front pillar side seal strips 102, 104, 106 is a long seal strip that is extruded from a predetermined elastic polymer material into a predetermined constant cross-sectional shape. Preferred elastic polymer materials include vulcanized elastic rubber (typically composed mainly of ethylene-propylene-diene rubber (EPDM)), olefin-based thermoplastic elastomer (TPO), and styrene-based thermoplastic elastomer (TPS). ) And the like.

Next, referring to FIG. 4, the configuration and mounting configuration of the seal strips 102, 104, 106 on the center pillar side, the upper pillar side, and the front pillar side of the seal strip assembly 100 constituting the seal device 3 according to the present embodiment. Will be explained.
4 is a cross-sectional view taken along the line IV-IV in FIG. 1. Based on this figure, the cross-sectional shape of the center pillar-side seal strip 102 according to this embodiment and the door frame (here, The center pillar side vertical side frame 61) will be described.
Note that the basic configuration of the upper seal strip 104 and the front pillar side seal strip 106 is substantially the same, and thus redundant description is omitted.

  As shown in FIG. 4, the center pillar side vertical side frame 61 is formed by bending a metal strip so that the vehicle inner side wall 28 and the vehicle outer side wall 30 are arranged substantially parallel in the width direction of the vehicle 1. A groove 32 is formed between the two side walls 28 and 30 along a substantially vertical direction (a direction orthogonal to the paper surface of FIG. 4). A vehicle interior recess 34 and a vehicle exterior recess 36 are formed in the vehicle interior side wall 28 and the vehicle exterior wall 30 in order to lock and fix a center pillar side seal strip 102 described later.

  On the other hand, as shown in FIG. 4, the center pillar side seal strip (seal strip) 102 according to the present embodiment is formed in a substantially U shape (in the groove 32) formed in a long shape by the extrusion molding of the polymer material described above. Before being attached, it is formed in an expanded U-shape). The main body 108 is guided from the door frame 22 and moved from the bottom strip 110 disposed at a position facing the end surface of the outer peripheral edge of the window plate 66, and from both ends in the width direction of the bottom strip 110. A vehicle interior side strip 112 and a vehicle exterior side strip 118 each project toward the center of the window opening, and a groove 124 is formed between both side strips 112, 118.

  The center pillar side seal strip 102 is formed with a vehicle inner side locking projection 114 protruding from the vehicle inner side side strip 112 to the vehicle inner side. Similarly, the vehicle exterior locking projection 120 is formed so as to project from the vehicle exterior side strip 118 to the vehicle exterior. As a result, in the state where the center pillar side seal strip 102 is mounted in the groove 32 of the center pillar side vertical side frame 61, it is prevented from coming out of the groove 32. The vehicle interior folding lip 116 and the vehicle exterior folding lip 122 shield the gap between the vehicle interior side wall 28 and the vehicle interior side strip 112 and the clearance between the vehicle exterior side wall 30 and the vehicle exterior side strip 118, respectively. ing.

Further, as shown in FIG. 4, the center pillar side seal strip 102 according to the present embodiment includes a vehicle inner side strip 112 side (a side facing the groove 124) to the vehicle outer side side strip 118 side (window plate). The tubular seal portion 130 having a substantially semicircular cross-sectional shape projecting toward the (66 side) is formed continuously over the entire length along the longitudinal direction. The tubular seal portion 130 is more flexible than the vehicle interior side strip 112 (main body portion 108) and can be deformed, and the inside is a gas (air in the present embodiment, hereinafter referred to as “air”). Has an interior space 134 filled. Thereby, when the atmospheric | air pressure in the internal space 134 increases and decreases, the external shape of the tubular seal part 130 (hollow wall 132) and the volume of the internal space 134 can be expanded and contracted.
The hollow wall 132 of the tubular seal portion 130 is integrated with the main body portion 108 by making the hollow wall 132 thinner than the thickness of the vehicle interior side strip 112 so that the hollow wall 132 can be deformed with a smaller force than the vehicle interior side strip 112. It is formed by extrusion (coextrusion), or by forming the hollow wall 132 using a material that is softer than the vehicle interior side strip 112 and has elastic restoring force, or a combination thereof. The hollow wall 132 and the vehicle interior side strip 112 are integrated by chemical bonding (typically heat fusion) at the end of the tubular seal portion 130 in the width direction during coextrusion molding. Thereby, stable joining is obtained at the end in the width direction of the hollow wall 132, and there is no inconvenience such as peeling of the hollow wall 132 and the vehicle interior side strip 112 at the joint. In addition, at least the inner surface side of the hollow wall 132 is preferably molded using a material containing a natural rubber component that is softer, more flexible, and more airtight than the material of the vehicle interior side strip 112. Thereby, even if the outer shape of the hollow wall 132 (tubular seal portion 130) repeatedly expands and contracts, defects such as cracks do not occur in the hollow wall 132, and the gas is sealed in the internal space 134 so that the gas is hollow. It is possible to prevent the fluid from passing through the wall 132 and flowing out. Furthermore, it is preferable that the hollow wall 132 is made of a material with less variation in hardness due to temperature change than the material forming the vehicle interior side strip 112. Accordingly, the hollow wall 132 itself maintains flexibility even when the temperature is low, and can be stably deformed even in a wide range of usage environments. Furthermore, it is preferable to form the surface of the tubular seal portion 130 smoothly. As a result, when the surface of the tubular seal portion is in contact with the surface of the smoothly formed window plate 66, close contact is made and the sealing performance is improved, and sound is prevented from being transmitted between the two surfaces and the sound insulation is improved.
With this configuration, when the air pressure in the internal space 134 fluctuates, particularly when the negative pressure is reached, the vehicle interior side strip 112 (main body portion 108) does not deform and move, and only the tubular seal portion 130 (hollow wall 132). Is stably deformed (reduced), and an unexpected positional shift or the like does not occur in the vehicle inner side strip 112. Even when the tubular seal portion 130 having the above-described configuration is insufficient in physical or chemical performance to withstand repeated separation and contact with the window plate 66, the above-described material is formed on the surface of the hollow wall 132. Are preferably laminated and integrated as appropriate.

  A low friction material layer (treatment layer) 128 having a static friction coefficient lower than that of the main body 108 is continuously formed in the longitudinal direction on the surface of the bottom strip 110 facing the end surface of the outer peripheral edge of the window plate 66. In addition, a plurality of irregularities (treatment layers) are continuously formed in the longitudinal direction on the surface of the outer side strip 118 facing the surface of the outer peripheral edge of the window plate 66, and the coefficient of static friction is higher than that of the main body 108. A low-friction material layer 128A having a low height is continuously formed in the longitudinal direction. As a result, the sliding resistance between the window plate 66 and the portion where the low friction material layer is formed can be reduced, so that the vertical movement of the window plate 66 becomes smoother. In addition, it is preferable to form the low friction material layer 128 also on the surface of the tubular seal portion 130 facing the outer peripheral edge of the window plate 66. More preferably, it is preferable that a plurality of irregularities are continuously formed in the longitudinal direction on the surfaces of the bottom strip 110 and the tubular seal portion 130. By forming these irregularities, the tubular seal portion 130 contacts the surface of the window plate 66 when the gas in the internal space 134 of the tubular seal portion 130 is sucked and the outer shape of the tubular seal portion is reduced, as will be described later. Even in this case, the substantial contact area between the end surface of the outer peripheral edge of the window plate 66 and the surface of the bottom strip 110 and the surface of the window plate 66 and the surface of the tubular seal portion 130 is larger than when there is no unevenness. This is effective in reducing the sliding resistance when the window plate 66 moves.

  Note that a vehicle outer side seal portion that extends in a folded shape from the vehicle outer side portion strip 118 and seals a part of the vehicle outer surface of the window plate 66 may be formed, but in FIG. 4, the center according to the present embodiment is formed. The pillar-side seal strip 102 does not have a vehicle-side seal portion that extends in a folded manner from the vehicle-side side strip 118. Thus, the vehicle outer surface of the window plate 66 can be in direct contact with the vehicle outer side strip 118, and the outer surface of the center pillar side vertical side frame 61 can be compared with the case where the vehicle outer side seal portion is formed. Step (d shown in FIG. 4) can be reduced. Reducing the level difference is effective in reducing the frictional resistance of air in the door frame 22 portion during travel of the automobile (vehicle) 1.

FIG. 5 is a longitudinal sectional view taken along the line VV in FIG. 1 and shows the structure in the longitudinal direction of the tubular seal portion of the seal device 3.
As shown in FIG. 5, the center pillar side seal strip (seal strip) 102 according to the present embodiment has a lower end portion in the longitudinal direction of the seal strip 102 which extends vertically beyond the lower end of the center pillar side vertical side frame 61. It is mounted along the groove 32 (see FIG. 4) of the side frame 61. A connecting tube 136 that connects an inner space 134 of the tubular seal portion 130 and a second space 209 of a cylinder of the negative pressure generator 200 described later is attached (connected) to the lower end of the seal strip 102 in the longitudinal direction. ) The inner shape of the connecting tube 136 is a semicircular shape corresponding to the inner space 134 on the seal strip side so that gas does not flow in and out of the connecting portion between the center pillar side seal strip 102 and the connecting tube 136, and true on the connecting tube side. It is securely attached to the seal strip 102 by a pipe-like connector 138 that gradually and smoothly changes into a circular shape. Similarly, a connecting tube 136 is attached (connected) to the lower end of the front pillar side seal strip 106 (see FIG. 1). The connecting tube may be attached at any position within the range of the center pillar-side vertical side frame 61 and the front pillar-side vertical side frame 63, but the seal strips 102, 106 can be arranged from the viewpoint of simplifying the structure. It is preferable to connect (attach) the lower end portion in the longitudinal direction (the lower end portion in the longitudinal direction of the tubular seal portion 130).
In the seal strip assembly 100 according to the present embodiment, the tubular seal portion 130 is formed over the entire length in the longitudinal direction, and the end portion on the upper side in the longitudinal direction of the center pillar side seal strip 102 is one of the upper seal strips 104. The abutting portion intersects the end portion and is joined (typically chemically) by adhesion or welding, and the longitudinally upper end portion of the front pillar side seal strip 106 is connected to the other end of the upper seal strip 104. It intersects the end (typically chemically) and joins. And in the joined terminal, internal space 134 of each tubular seal part 130 is connected so that ventilation is possible. As described above, the connection tubes 136 and 136 connected to the negative pressure generator 200 are attached to the lower end portions of the center pillar side and front pillar side seal strips 102 and 106, so The internal space 134 is maintained in a substantially sealed state. By operating an atmospheric pressure adjusting mechanism 150 described later, the gas in the internal space 134 of the tubular seal portion 130 flows into and out of the internal space 134 via the connecting tube 136, The atmospheric pressure increases and decreases.
If the upper seal strip 104 is not formed with a tubular seal portion, the upper end portion (upper side) in the longitudinal direction of the tubular seal portion formed on the center pillar side seal strip 102 and / or the front pillar side seal strip 106 is used. The frame 50 side end) is closed or the hollow wall is joined to the vehicle interior side strip to prevent gas from flowing in and out (leakage) from the upper end in the longitudinal direction of the tubular seal portion. Thereby, the internal space of the tubular seal part is maintained in a substantially sealed state. As the above-mentioned joining means, for example, a method of bonding and joining the contact portion between the hollow wall and the vehicle interior side strip using an adhesive, a chemical method such as fusing the contact portion with ultrasonic waves or high-frequency vibrations, etc. May be joined using well-known means such as a method of mechanical joining, a method of mechanically joining the inner side strip with a hollow wall sandwiched between separate clips or staples, etc. May be.

Next, the structure of the atmospheric pressure adjustment mechanism 150 according to the present embodiment will be described with reference to FIGS. FIG. 6 is a plan view showing a part of the structure of the atmospheric pressure adjustment mechanism 150 according to the first embodiment. In the present embodiment, a link driving mechanism using a bar (bar) as means for transmitting force to the atmospheric pressure adjusting mechanism 150 will be described. However, instead of the bar (bar), a wire, cable, or string is used. Also good. Therefore, in the present application, the transmission means using the bar (bar), wire, cable and string is referred to as a “link driving mechanism”. FIG. 7 is a front view showing the structure of the link drive mechanism 168 according to the first embodiment. FIG. 8 is a cross-sectional view showing the structure of the negative pressure generator 200 according to the first embodiment.
As shown in FIGS. 6 to 8, the atmospheric pressure adjusting mechanism 150 according to the present embodiment includes a negative pressure generator 200 and a piston drive link 176 (hereinafter referred to as a bar) B having one end connected to a piston rod 215. , Simply referred to as “piston drive link”), a link drive mechanism 168 connected to the negative pressure generator 200 and a clutch 158, and an electric motor (drive source) 80 for driving the window plate elevating mechanism 74. Driven by. The electric motor 80 can be electrically connected to and disconnected from a battery 151 (see FIG. 9) that is a power supply source. The electric motor 80 is preferably an electric motor that can rotate forward and backward. In the electric motor 80, a small-diameter bevel gear 154 is attached to a shaft (drive shaft) 152 of the electric motor. A large-diameter bevel gear 156 (reduction gear) is disposed in mesh with the small-diameter bevel gear 154, and a first driven shaft 164 is attached to the large-diameter bevel gear 156. With the structure described above, the direction of the shaft 152 of the electric motor is different from the direction of the rotation shaft and intersects at an angle of 90 degrees, and the first driven shaft 164 is driven to rotate at a lower speed than the shaft 152 of the electric motor and generate high rotational torque. put out. One of the first driven shafts 164 is connected to the window plate elevating mechanism 74, and the window motor elevating mechanism 74 is driven by driving the electric motor 80 and rotating the first driven shaft 164 in the forward and reverse directions. Is activated, and the window plate 66 can move up and down. The other is connected to a first clutch plate 160 of a clutch 158 (electromagnetic clutch).
The second clutch plate 162 of the clutch 158 is connected to the second driven shaft 166, and the other end of the second driven shaft 166 is connected to the link drive mechanism 168. When a load (rotational torque) exceeding a predetermined value is applied to the second driven shaft 166, slip occurs between the first and second clutch plates 160, 162, causing the first clutch plate 160 to idle. To do. As will be described later, the clutch 158 is a power supply source battery 151 (see FIG. 9) by operating the window plate raising / lowering selection switch 20 to connect the terminal to the contact and energizing it (electrically turned on). The first clutch plate 160 and the second clutch plate 162 are connected to each other, and the connection is released by cutting off the current (turning off electrically).

  As shown in FIGS. 6 and 7, the link drive mechanism 168 according to the present embodiment is attached to the second driven shaft 166 and rotates together with the second driven shaft 166 and converts the rotational motion into a linear motion. A circular rotary drive plate 170 that is mounted on the door body 8 and is provided between the drive plate 170 and the second clutch plate 162 to rotate the rotary drive plate 170 within a predetermined rotation angle range. And a piston drive link 176, and a stopper 180 that prevents rotation beyond the angle. A circular guide groove 172 is formed in the rotation drive plate 170. A stopper pin 182 protruding from the stopper 180 is inserted in the guide groove 172 to allow the rotation drive plate 170 to move within a predetermined rotation angle range. A connection part 174 to which one end of the piston drive link 176 is connected is formed on the outer periphery of the drive plate 170, and one end of the piston drive link 176 is connected to the rotation drive plate 170 at the connection part 174 (second). The distance from the center of the driven shaft 166 to the connecting portion 174 of the piston drive link 176 is r1). The other end of the piston drive link 176 is connected to a piston rod 215 of a negative pressure generator 200 described later.

  When the electric motor 80 rotates forward, the rotational drive plate 170 rotates forward in the direction of arrow X7 in FIG. 7, and when the electric motor 80 rotates reversely, the rotational drive plate 170 moves in the direction of arrow Y7 in FIG. Reverse rotation. In the piston drive link 176 indicated by a two-dot chain line in FIG. 7, the rotary drive plate 170 rotates forward and the terminal end of the guide groove 172 contacts the stopper pin 182, and the rotary drive plate 170 is in the contact position. The position of the piston drive link 176 is shown in a state in which the rotation beyond the range is blocked. In the above state, the connecting portion 174 of the piston drive link 176 draws an arc locus and is displaced in the horizontal direction by the distance a, and the piston 210 is moved through the piston rod 215 in the direction of the arrow X6 in FIGS. Displace only. In this state, when the electric motor 80 continues to be driven (rotated) and the rotational torque acting on the second clutch plate 162 reaches a predetermined value, the electric motor 80 moves between the first clutch plate 160 and the second clutch plate 162. As a result of slippage, the first clutch plate 160 idles and excessive rotational torque is not transmitted to the second driven shaft 166. When energization is stopped (electrically turned off), the first clutch plate 160 and the second clutch plate 162 are separated from each other, and no rotational torque is transmitted to the second clutch plate 162, and at the same time, the window plate is raised and lowered. The operation of the mechanism 74 is also stopped. The rotational torque of the second clutch plate 162 compresses a coiled return spring 220, which will be described later, and displaces the piston 210 to reduce the atmospheric pressure in the internal space 134 of the tubular seal portion 130, thereby generating a negative pressure. Is set to a sufficient force. In this embodiment, the distance from the center of the second driven shaft 166 to the connecting portion 174 of the piston drive link 176 is r1, but when the movement distance of the piston drive link 176 needs to be different, The distance from the center of the second driven shaft 166 to the link connecting portion 174 may be adjusted, or a guide groove having a different shape may be formed.

As shown in FIG. 8, the negative pressure generator 200 of the atmospheric pressure adjustment mechanism 150 according to the present embodiment is a fluid pressure cylinder 205 having a piston 210 and a piston rod 215 inside, and increases or decreases the atmospheric pressure in the internal space 134. This is a piston mechanism. In the present embodiment, the cylinder 205 uses a gas such as air or gas as the fluid. The piston rod 215 is connected to the end of the piston drive link 176 on the cylinder 205 side at the piston connecting portion 230. Inside the cylinder 205, there is provided a coil-shaped return spring 220 that applies a force in the direction in which the piston rod 215 is always retracted (the direction of the arrow Y6 in FIG. 8). At the front end of the cylinder 205, a ventilation port 225 is provided that allows air to flow in and out of the outside and the space on the front side of the cylinder 205 (the first space 207 of the cylinder). A connecting tube 136 is connected to the rear end portion of the cylinder 205, and the inner space 134 of the tubular seal portion 130 and the rear space (cylinder second space 209 of the cylinder 205) through the connecting tube 136. ) Communicates. As shown in FIG. 8, the connection tube 136 according to the present embodiment is branched into two in the middle, one of which is connected to the tubular seal portion 130 of the center pillar side seal strip 102 and the other one is the front. It is connected to the tubular seal portion of the pillar side seal strip 106.
When the link driving mechanism 168 is operated, the atmospheric pressure adjusting mechanism 150 pulls (displaces) the piston rod 215 in the direction of the arrow X6 in FIG. 8, and the piston 210 is indicated by a two-dot chain line from the position indicated by the solid line in FIG. It can be advanced to a position to reduce the volume of the internal space 134 of the tubular seal 130 and reduce the air pressure in the internal space 134. Even if the rotary drive plate 170 described above rotates by a predetermined angle and the connecting portion 174 moves by a distance a and is prevented from further rotation, the clutch 158 is energized and the first clutch plate 160 is idled. As long as this is the case, the above state is maintained. When the operation of the electric motor 80 is stopped and the link drive mechanism 168 is deactivated, the connection between the first clutch plate 160 and the second clutch plate 162 is released, and at the same time, the piston 210 is moved by the restoring force of the return spring 220. The pressure in the internal space 134 is increased to the original pressure by being retracted (displaced to the original position) in the direction of the arrow Y6 in FIG.
As described above, the restoring force of the return spring 220 is larger than the force obtained by adding the force to retract the piston 210 and the force to reversely rotate the rotary drive plate 170 in the direction of the arrow Y7 via the piston drive link 176. Is set.

FIG. 9 is a wiring diagram illustrating the principle of operation control of the clutch 158 and the electric motor 80. In the drive circuit 195 in the same figure, the window plate raising / lowering selection switch 20 is located in the neutral position (not operating and stopped). As shown in FIG. 9, when the window plate lifting / lowering selection switch 20 provided in the armrest 18 of the door body 8 is switched to the window plate “up”, the electric motor 80 and the clutch 158 (indicated by an arrow X9 in FIG. 9). Direction), the terminals 190 and 190 are connected to the first contact 185A and the third contact 185C, respectively, so that electric power is supplied from the battery 151 (a positive voltage is applied), and the electric motor 80 is rotated forward. At the same time, the clutch 158 is connected (the first clutch plate 160 and the second clutch plate 162 are connected). Similarly, when the window plate raising / lowering selection switch 20 is switched to the window plate “down” (in the direction of arrow Y9 in FIG. 9), the terminals 190 and 190 are connected to the second contact 185B and the fourth contact 185D, respectively. Thus, the electric power from the battery 151 is supplied (the reverse voltage is applied), the electric motor 80 rotates in the reverse direction, and the clutch 158 is connected (the first clutch plate 160 and the second clutch plate 162 are connected). ). On the other hand, by switching the window plate lifting / lowering selection switch 20 to neutral and separating the terminals 190 and 190 from the first contact 185A, the third contact 185C or the second contact 185B and the fourth contact 185D, respectively, the battery 151 At the same time that the electric motor 80 is cut off and the operation of the electric motor 80 is stopped, the clutch 158 is released (the first clutch plate 160 and the second clutch plate 162 are separated).
The drive circuit 195 described above explains the principle of operation of the electric motor and clutch related to the operation of the seal device, and may be the same as the conventional circuit, and does not characterize the present invention, so that the switch 20 is neutral. A detailed description of the self-holding circuit and the like that keeps the electric motor 80 operating even after returning to FIG.

Next, when the window plate 66 moves up (typically, when the window plate 66 moves from the open state to the closing direction), that is, the electric motor 80, the window plate lifting mechanism 74, and the atmospheric pressure adjustment. The function (action, effect) of the center pillar seal strip 102 corresponding to the operation of the mechanism 150 and the movement of the window plate 66 will be described in detail with reference to the drawings.
FIG. 10 illustrates the relationship between the shape and position of the tubular seal portion 130 and the operation of the atmospheric pressure adjustment mechanism 150 at a position where the outer peripheral edge of the window plate 66 exists in the center pillar side seal strip 102 (in the groove 124). . When the window plate elevating mechanism 74 and the atmospheric pressure adjusting mechanism 150 are simultaneously operated, the gas in the inner space 134 of the tubular seal portion 130 is sucked by the operation of the cylinder 205 and the inner space 134 becomes negative pressure, so that the tubular seal portion 130 is second. The position is displaced from the position (the position of the tubular seal portion 130 represented by the two-dot chain line indicated by reference numeral L2 in FIG. 10) to the third position (the position of the tubular seal portion 130 indicated by the solid line indicated by reference numeral L3 in FIG. 10). It is sectional drawing. Note that the window plate lifting mechanism 74 and the atmospheric pressure adjusting mechanism 150 are both inactive, and the outer peripheral edge of the window plate 66 does not exist in the center pillar side seal strip 102 (in the groove 124) (for example, the window plate 66). The shape and the position of the tubular seal portion 130 in the fully open state of the seal strip) are defined as the first position (the position of the tubular seal portion 130 indicated by the one-dot chain line in FIG. 10).

When the window plate 66 is raised, the window plate “rise” of the window plate raising / lowering selection switch 20 provided on the armrest 18 is pushed. Accordingly, the terminals 190 and 190 shown in FIG. 9 are connected to the first contact 185A and the third contact 185C, respectively, the forward rotation circuit of the electric motor 80 is closed, and the electric motor 80 and the clutch 158 are electrically connected. At the same time as the electric motor 80 starts rotating, the clutch 158 is connected (the first clutch plate 160 and the second clutch plate 162 are connected). As shown in FIG. 7, the rotational speed of the electric motor 80 is decelerated by the combination of the bevel gears 154 and 156 (rotational torque is increased) to drive the first driven shaft 164 in the forward rotational direction.
Since one of the first driven shafts 164 is connected to the window plate elevating mechanism 74, the window plate elevating mechanism 74 is operated by the rotation of the first driven shaft 164 to move the window plate 66 up and down. The other one of the first driven shafts 164 is connected to the clutch 158, the second driven shaft 166 rotates via the clutch 158, and the second driven shaft 166 rotates the rotation drive plate 170 in the forward rotation direction. Drive in the direction of arrow X7 in FIG.
As shown in FIG. 7, when the rotary drive plate 170 is driven in the forward rotation direction, the piston drive link 176 is pulled (rotated) as shown by a two-dot chain line in the drawing to horizontally move the link connecting portion 174. Displace by a distance a in the direction.

  As shown in FIG. 8, the other end of the pulled piston drive link 176 is connected to the piston 210 via the piston rod 215, so that the piston 210 compresses the coiled return spring 220. It moves forward (displaces) by being pulled by the length dimension a in the direction of the arrow X6 in FIG. As a result, the pressure inside the second space 209 of the cylinder 205 becomes negative, and at the same time, the gas in the inner space 134 of the tubular seal portion 130 is forced into the second space 209 of the cylinder via the connection tube 136. Therefore, the amount of gas in the internal space 134 decreases, and the atmospheric pressure decreases compared to when the gas is filled (hereinafter, simply described as “negative pressure is generated”). . As the atmospheric pressure in the internal space 134 decreases, the hollow wall 132 of the tubular seal portion 130 is pushed by the atmospheric pressure and deforms in the shrinking direction, and the volume of the internal space 134 decreases and the hollow wall 132 of the tubular seal portion 130 decreases. It is elastically displaced toward the vehicle inner side strip 112 (displaced from the vehicle outer side position shown by a two-dot chain line in FIG. 5 to the vehicle inner side strip 112 side position shown by a solid line). When the piston 210 is pulled by the dimension a in the direction of the arrow X6 in FIG. 8, the gas in the first space 207 of the cylinder is discharged out of the cylinder 205 through the ventilation port 225.

  As shown in FIG. 10, as the gas in the inner space 134 of the tubular seal portion 130 is sucked into the second space 209 of the cylinder and the amount of gas in the inner space 134 decreases, the tubular seal portion. 130 (hollow wall 132) is displaced toward the vehicle interior side strip 112. As a result, the entire surface of the tubular seal portion 130 in the longitudinal direction is displaced to the third position L3 where the surface of the tubular seal portion 130 is separated from the outer peripheral edge on the vehicle inner side of the window plate 66 to be in a non-contact state (tubular A gap is generated between the surface of the seal portion 130 and the surface of the window plate 66, and a non-contact state occurs). Even when the non-contact state does not occur, the pressing force (P1) per predetermined length of the tubular seal portion 130 against the outer periphery of the window plate 66 on the vehicle inner side is reduced more than the pressing force (P2) at the second position L2. Can be brought into contact with each other. Therefore, when the tubular seal portion 130 and the window plate 66 are not in contact with each other when the window plate 66 is raised, the pressing force is zero and is independent of the magnitude of the dynamic friction coefficient between the tubular seal portion 130 and the window plate 66. In addition, the sliding resistance (dynamic friction coefficient × pressing force (= 0)) between the surface of the window plate 66 and the tubular seal portion 130 is eliminated. Further, when the pressing force P1 of the tubular seal portion 130 against the window plate 66 is in a state of being smaller than P2, the sliding resistance between the surface of the window plate 66 and the seal portion 130 (dynamic friction coefficient × pressing force P1). (<P2)) is smaller than when contacting with the pressing force P2. The state where the tubular seal portion 130 is displaced toward the inside of the vehicle is maintained while the electric motor 80 is operated and the window plate 66 is moved upward. In the above state, the window plate 66 can be rotationally displaced within a range limited to the vehicle inner side and the vehicle outer side with the window plate holder 68 as the center (see FIG. 3), so the window plate 66 is slightly toward the vehicle inner side. Displace. Therefore, even if the window plate 66 is separated from or in contact with the vehicle outer side strip 118, the contact pressure is smaller than before the tubular seal portion 130 is reduced.

  In the case of the electric motor 80 that is driven when the window plate 66 moves upward and becomes fully closed, the forward rotation circuit is opened by a position sensor and an overcurrent lock circuit (not shown), and is electrically turned off. The motor 80 stops operating. At the same time, the current of the clutch 158 is stopped and the clutch 158 is released. When the window plate 66 is stopped in a half-open state, when the selection switch 20 is stopped and the switch 20 returns to the neutral position, the same state as described above is obtained and the electric motor 80 stops.

As shown in FIG. 8, when the electric motor 80 is stopped and the clutch 158 is released as described above, the piston 210 is pushed back to the rear of the cylinder 205 by the elastic restoring force of the return spring 220 in the cylinder 205. (Displaced in the direction of arrow Y6 in FIG. 8), the gas flows from the outside into the cylinder 205 (the first space 207 of the cylinder) through the ventilation port 225. When the piston 210 is pushed back, the gas in the second space 209 of the cylinder is supplied into the internal space 134 of the tubular seal portion 130 via the connection tube 136.
Due to the push-back action, the atmospheric pressure in the internal space 134 of the tubular seal portion 130 returns to the original atmospheric pressure (the atmospheric pressure when the window plate elevating mechanism 74 is inactive) or the atmospheric pressure when the electric motor 80 is operating. Is generated in the internal space 134, the tubular seal portion 130 is positioned at the position indicated by the two-dot chain line shown in FIGS. 5 and 10. Returning to L2, the outer peripheral edge of the window plate 66 is pressed toward the outside of the vehicle. Therefore, the space between the surface of the window plate 66 and the door frame 22 is well sealed.
In addition, by providing a flow rate control valve in the ventilation port 225, the amount of gas per hour flowing into the cylinder 205 from the ventilation port 225 is slightly less than the amount of gas discharged from the ventilation port 225 per unit time. When the piston 210 is moved backward with a delay from the stop of the movement of the window plate (practically, 1 second to a few seconds), the tubular seal portion is moved before the window plate 66 stops (moving). It is possible to prevent the 130 from coming into contact with the window plate 66 and the tubular seal portion 130 to slowly come into contact with the window plate 66 to prevent the generation of sound.

  Next, when the window plate 66 descends (typically, when the window plate 66 moves from the closed state to the opening direction), that is, the electric motor 80, the window plate elevating mechanism 74, and the atmospheric pressure adjustment. The function (action, effect) of the center pillar side seal strip 102 corresponding to the operation of the drive mechanism 150 and the movement of the window plate 66 will be described with reference to the drawings. Since the operation at this time is opposite to that when the window plate is raised, only the operation specific to the reverse case will be described.

  When the window plate 66 is lowered, the window plate “descent” of the window plate raising / lowering selection switch 20 provided on the armrest 18 is pushed. 9 are connected to the second contact 185B and the fourth contact 185D, respectively, the reverse rotation circuit of the electric motor 80 is closed, and the electric motor 80 and the clutch 158 are electrically connected. At the same time as the electric motor 80 starts rotating, the clutch 158 is connected (the first clutch plate 160 and the second clutch plate 162 are connected).

Since one of the first driven shafts 164 is connected to the window plate elevating mechanism 74, the window plate elevating mechanism 74 is operated by the rotation of the first driven shaft 164 to move the window plate 66 downward. The other one of the first driven shafts 164 is connected to the clutch 158, the second driven shaft 166 rotates via the clutch 158, and the second driven shaft 166 rotates the rotation drive plate 170 in the reverse rotation direction. Drive in the direction of arrow Y7 in FIG.
When the rotary drive plate 170 is driven in the reverse rotation direction, the piston drive link 176 is pulled (rotated) to move the link connecting portion 174 in the horizontal direction by the distance a in the same manner as when the window plate 66 moves upward. Displace. That is, even if the electric motor 80 rotates forward or backward, the piston drive link 176 can be pulled in the same direction and the piston can be forcibly moved in the same direction. As shown in FIG. 8, the other end of the pulled piston drive link 176 is connected to the piston 210 via the piston rod 215, so that the piston 210 compresses the return spring 220 to It is pulled (displaced) by a distance a in the direction of the arrow X6. The following is the same as when the window plate 66 is raised. Thereby, the same effect as when the window plate 66 is raised is obtained.

  Next, the window plate 66 is moving upward (typically, moving from the open state to the closing direction), or the window plate 66 is moving downward (typical). In the following, a brief description will be given of the case where the window plate 66 is moved halfway from the closed state (in the direction of opening).

While the window plate 66 is moving up or down, the window plate raising / lowering selection switch 20 is neutralized, and the terminals 190, 190 are connected to the first contact 185A, the third contact 185C, or the second contact 185B, When separated from the fourth contact point 185D, the forward rotation circuit or the reverse rotation circuit is opened, the electric motor 80 is stopped, and the clutch is released. The operation after the motor 80 stops and the clutch is released is the same as that described above.
As described above, when the tubular seal portion 130 is retracted toward the vehicle inner side, the pressing force applied to the window plate 66 in the direction perpendicular to the surface of the window plate 66 from the vehicle inner side to the vehicle outer side is released. (The pressing force becomes zero or decreases). Note that a vehicle outer side seal portion may be formed on the vehicle outer side strip 118.

  In the first embodiment, the tubular seal portion 130 is not in contact with the surface of the window plate 66 even when the window plate 66 moves up or down. The example in which the tubular seal portion 130 contacts the surface of the window plate 66 in a state where the pressing force per predetermined length of 130 is reduced has been described. However, the present invention is not limited to such a configuration, and the tubular seal portion 130 is not in contact with the surface of the window plate 66 only when the window plate 66 moves up at least, or the predetermined length of the tubular seal portion 130 is exceeded. The tubular seal portion 130 comes into contact with the surface of the window plate 66 in a state where the pressing force is reduced, and when the window plate 66 moves downward, the tubular seal portion 130 is in the same state as when the window plate 66 is stopped. The object according to the present invention can be achieved even if is in contact with the window plate 66.

  Hereinafter, as a second embodiment, the tubular seal portion 130 is not in contact with the surface of the window plate 66 only when the window plate 66 moves upward, or the pressing force per predetermined length of the tubular seal portion 130 is reduced. A structure in which the tubular seal portion 130 is in contact with the surface of the window plate 66 in the state of being made will be described with reference to the drawings.

First, a preferred example in which the above operation is exhibited by changing the drive circuit 195 that controls the operation of the clutch 158 will be described.
FIG. 18 is a wiring diagram illustrating the principle of control of the operation of the clutch 158 and the electric motor 80 according to the second embodiment. FIG. 19 is a wiring diagram illustrating a current flow when the window plate is moved upward in the drive circuit 195A according to the second embodiment. FIG. 20 is a wiring diagram illustrating a current flow when the window plate is moved downward in the drive circuit 195A according to the second embodiment. In FIG. 19 and FIG. 20, the line through which the current flows is indicated by a bold line, and the direction in which the current flows is also shown.

As shown in FIG. 18, the one line connected to the clutch 158 can be connected to the first contact 185A on the side where the window plate 66 is raised in the selection switch 20 as in the first embodiment. The other line is different from the first embodiment in that it is connected to the battery 151. When the window plate “rise” of the selection switch 20 is pushed by the above structure, a current flows in the drive circuit 195A as shown by a thick line in FIG. 19 (current flows in the electric motor 80 and the clutch 158), and the electric motor 80 And the clutch 158 is operated (connected) at the same time as it rotates in the forward direction. The operation after the clutch 158 is operated is the same as the operation when the window plate “up” of the selection switch 20 is pushed in the first embodiment.
On the other hand, when the window plate “down” of the selection switch 20 is pressed, a current flows through the drive circuit 195A (current flows through the electric motor 80) as shown by a thick line in FIG. However, since one line of the clutch 158 is not connected to the fourth contact 185D on the side where the window plate 66 is lowered in the selection switch 20, no current flows through the clutch 158 and the clutch 158 operates. (I.e., the window plate 66 moves downward, but the atmospheric pressure adjusting mechanism 150 does not operate and the atmospheric pressure in the internal space 134 does not decrease).
Therefore, in the window sealing device 3 having the above-described structure, when the window plate 66 moves upward, the tubular seal portion 130 is not in contact with the surface of the window plate 66, or the tubular seal portion 130 per predetermined length. Since the tubular seal portion 130 contacts the surface of the window plate 66 in a state where the pressing force is reduced, the sliding resistance between the window plate 66 and the tubular seal portion 130 can be made zero or reduced. On the other hand, when the window plate 66 moves downward, the tubular seal portion 130 contacts the window plate 66 while maintaining a pressing force larger than the reduced pressing force, so that the tubular seal portion 130 supports the window plate 66. The window plate 66 can be moved down stably.

Further, in place of the drive circuit 195A changed as described above, in the atmospheric pressure adjustment mechanism 150 (see FIG. 6), the rotational force in one direction of the first driven shaft 164 is applied to the second driven shaft 166 as the clutch 158. A clutch with a function (typically a function of a one-way clutch having a ratchet and a pawl) that does not rotate to transmit the rotational force to the second driven shaft 166 when a rotational force in the reverse direction is applied. May be used.
With such a configuration, when the electric motor 80 rotates forward to move the window plate 66 upward, the rotational force of the first driven shaft 164 is transmitted to the second driven shaft 166 via the clutch 158 and the atmospheric pressure adjustment mechanism 150. Is activated (the link rotation drive plate 170 is driven in the forward rotation direction (direction X7 in FIG. 7), and the piston rod 215 is pulled in the direction X6 in FIGS. 6 and 8, thereby reducing the air pressure in the internal space 134. Therefore, the same effect as when the window plate of the first embodiment moves up and down is obtained.
On the other hand, when the electric motor 80 rotates in the reverse direction to move the window plate 66 downward, the clutch (one-way clutch) 158 idles, so that the rotational force of the first driven shaft 164 is transmitted to the second driven shaft 166. In other words, the atmospheric pressure adjustment mechanism 150 does not operate (that is, the atmospheric pressure in the internal space 134 does not decrease). Therefore, in the window sealing device 3 including the clutch 158 having the above-described structure, the same effect as that obtained when the drive circuit 195A described above is used can be obtained.

  In the first and second embodiments described above, the power of the electric motor 80 is transmitted to the link drive mechanism 168 by the clutch (electromagnetic clutch) 158 controlled by electricity. The configuration may be such that the power of the electric motor 80 is transmitted to the link drive mechanism 268 using the fluid clutch 258. Hereinafter, some modified examples of the first embodiment or the second embodiment will be described. The modification shown in FIG. 11 is a preferred modification of the first embodiment, and is a plan view showing the structure of the atmospheric pressure adjustment mechanism according to the first modification. FIG. 12 is a front view showing the structure of the link drive mechanism according to the first modification.

As shown in FIG. 11, the atmospheric pressure adjustment mechanism 250 according to the first modification includes a negative pressure generator 200 and a link drive mechanism 268 that is connected to the negative pressure generator 200 via a piston drive link 276. Then, it is driven by the electric motor 80. The rotational torque of the electric motor 80 is transmitted to the driven shaft 266 via the small-diameter bevel gear 154 and the large-diameter bevel gear 156, and the driven shaft is driven (rotated). One of the driven shafts 266 is connected to the window plate elevating mechanism 74. When the driven shaft 266 is rotated by driving the electric motor 80, the window plate elevating mechanism 74 is operated, and the window plate 66 is moved up and down. Can move down. The other driven shaft 266 is connected to the viscous fluid clutch 258.
As shown in FIGS. 11 and 12, the link driving mechanism 268 according to this modification is provided with a driven shaft 266, a viscous fluid clutch 258, and a door body provided between the viscous fluid clutch 258 and the large-diameter bevel gear 156. 8 has a stopper 280 mounted in the piston 8 and a piston drive link 276. Although not shown in FIG. 12, the stopper 280 has the same structure as that of the first embodiment. The viscous fluid clutch 258 includes a rotating blade 275 connected to a driven shaft 266 inside a cylindrical case 285, and the inside of the case 285 is filled with a viscous fluid. A protrusion 290 is formed on the outer periphery of the rotary drive plate 270 of the viscous fluid clutch 258. The piston drive link 276 is a straight line connecting the center of the protrusion 290 and the driven shaft 266, and is connected to a connection portion 274 formed on the outer periphery of the rotation drive plate 270.

As shown in FIG. 12, when the electric motor 80 rotates forward, the rotational drive plate 270 rotates forward (arrow X12 in FIG. When the electric motor 80 rotates in the reverse direction, the rotation drive plate 270 rotates in the reverse direction (the direction of the arrow Y12 in FIG. 12). The piston drive link 276 indicated by a two-dot chain line in FIG. 12 is in a state where the rotation drive plate 270 rotates forward and contacts the stopper pin 282 (see FIG. 11), and the rotation drive plate 270 is prevented from rotating. The piston drive link 276 is displaced by a distance b in the horizontal direction of the link and is connected to the other end of the piston drive link 276 via a piston rod 215. The piston 210 is displaced by a distance b in the direction of the arrow X6 in FIGS.
With this structure, in addition to the same effects as in the case of the first embodiment, the structure is simplified because it is not necessary to connect and release the clutch by an electric signal. In addition, as a viscous fluid clutch, if a rotating blade is provided in the cylindrical case and the inside is filled with viscous fluid, it can be used without limitation.

  As described above, the preferred one modification example (first modification example) of the first embodiment has been described with reference to FIGS. 11 and 12. In the sealing device using the viscous fluid clutch 258, the function of the above-described one-way clutch is described. When the window plate 66 moves upward, the tubular seal portion 130 is not in contact with the surface of the window plate 66 or the pressing force per predetermined length of the tubular seal portion 130 is increased. It is possible to realize that the tubular seal portion 130 contacts the surface of the window plate 66 in a reduced state.

  In the first and second embodiments described above (including the first modification), the electric motor used as the drive source for driving the window plate elevating mechanism is also used as the drive source for the atmospheric pressure adjustment mechanism. The atmospheric pressure adjustment mechanism may be driven using a drive source that is independent of the electric motor. Hereinafter, two preferred modified examples (second modified example and third modified example) of the cable drive mechanism will be described in detail with reference to the drawings. FIG. 13 is a plan view showing the structure of the atmospheric pressure adjustment mechanism according to the second modification. FIG. 14 is a plan view showing the structure of the atmospheric pressure adjustment mechanism according to the third modification.

As shown in FIG. 13, the atmospheric pressure adjustment mechanism 350 according to the second modification includes a rotary actuator 368 that can rotate forward and backward. The drive shaft 366 of the rotary actuator 368 is connected to a circular rotary drive plate 370 that converts the rotational motion of the drive shaft 366 into the linear motion of the piston drive link 376. Similar to the drive plate 170 according to the first embodiment, the rotary drive plate 370 includes a connecting portion 374, and the piston drive link 376 is connected to the connecting portion 374. When the rotary actuator 368 according to this modification is electrically connected to the battery 151, the drive shaft 366 is rotated by energization, and the piston 210 (piston rod 215) is pulled in the direction of the arrow X6 in FIG. The atmospheric pressure in the internal space 134 of the tubular seal portion 130 decreases (negative pressure is generated). On the other hand, since the drive shaft 366 returns to the original state by stopping the energization, the piston 210 (piston rod 215) is displaced to the original position, and the atmospheric pressure in the internal space 134 returns to the original state. An example of the rotary actuator 368 is a rotary solenoid. With this configuration, in addition to the same effects as in the case of the first embodiment, the structure of the mechanism for driving the link is simplified. The rotary actuator 368 is not limited to being provided at a position corresponding to the window plate elevating mechanism 74 as long as there is room in the accommodation space.
By applying the drive circuit 195A to the atmospheric pressure adjustment mechanism 350 (that is, using a rotary actuator 368 instead of the clutch 158 in FIG. 18), the same effect as in the second embodiment can be obtained.

As shown in FIG. 14, the atmospheric pressure adjustment mechanism 450 according to the third modification example is an example in which linear motion is performed, and a mechanism for converting rotational motion into linear motion is incorporated therein, and an operating arm 470 that moves forward and backward is provided. A linear actuator 468 is provided. A connecting portion 474 is formed on the operating arm 470. A piston drive link 476 is connected to the connecting portion 474. When the linear actuator 468 according to this modified example is electrically connected to the battery 151, the operating arm 470 is drawn into the actuator 468, whereby the piston 210 (piston rod 215) is moved in the direction of the arrow X6 in FIG. The air pressure in the inner space 134 of the tubular seal portion 130 is reduced by pulling (negative pressure is generated). On the other hand, when the energization is stopped, the pulling force acting on the piston 210 (piston rod 215) is released, and the piston 210 (piston rod 215) is displaced to the original position by the pushing back action of the return spring 220, and the internal space. The atmospheric pressure in 134 returns to the original state. Examples of the linear actuator 468 include a linear solenoid and a linear ball screw mechanism that converts rotational motion into linear motion. With this configuration, in addition to the same effects as those of the first embodiment, the structure of the sealing device is simplified.
By applying the drive circuit 195A to the atmospheric pressure adjustment mechanism 450 (that is, using a linear actuator 468 instead of the clutch 158 in FIG. 18), the same effect as in the second embodiment can be obtained.

  Further, in the atmospheric pressure adjustment mechanisms 350 and 450, a device such as a timer is incorporated in the circuit, and the operation of the electric motor 80 is delayed (for example, a fraction of a second) from the operation of the rotary actuator 368 or the linear actuator 468. Then, since the window plate starts moving up and down after the tubular seal portion is retracted, the sliding resistance between the tubular seal portion and the window plate at the start of the window plate can be more reliably reduced.

In the first and second embodiments described above (including the first to third modifications), the tubular seal portion having a substantially semicircular cross-sectional shape protruding from the inner surface of the vehicle inner side strip toward the vehicle outer side. However, the present invention is not limited to such a form. Hereinafter, two preferred modified examples (fourth and fifth modified examples) relating to the structure of the seal strip will be described with reference to the drawings. FIG. 15 is a cross-sectional view showing a seal strip according to a fourth modification. In the drawings for explaining the present modification, members and mechanisms that are substantially the same as those in the first embodiment are given the same reference numerals, and redundant explanations are omitted.
As shown in FIG. 15, the seal strip 502 according to the fourth modification is integrally formed from the opening edge side (protruding tip side) of the vehicle interior side portion strip 112 to the center side in the width direction of the bottom strip 110 (see FIG. 4).
