Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an improvement of a panel fully closing/stopping mechanism of a drive device for sliding and tilting a roof panel of a vehicle such as a passenger car.

(Prior art) For example, a passenger car is equipped with a sunroof device for ventilation, etc. As an example of the conventional technology, the technology shown in Figs.
-60909 Publication).

In this prior art, an opening 2 of a vehicle roof 1 is made openable and closable by a panel 3, the rear part of the panel 3 is supported via an opening/closing mechanism 7 consisting of a cam plate 4, a link 5, a slider 6, etc., and the slider 6 is By pushing and pulling the threaded cable 8, the panel 3 is moved to the eighth position.
It is configured to be movable from a fully closed position A shown by a solid line in the diagram to a sliding open position B shown by a chain line and a tilting open position C shown by a chain double dot line.

In such a roof panel sliding and tilting drive device, the panel 3 is rotated in the same direction from the sliding open position B to the fully closed position A and from the fully closed position A to the tilting open position C. In order to move the panel 3, a mechanism is required to accurately stop the panel 3 at the fully closed position A.

The fully closed stop mechanism 10 of the prior art has a motor 1
a shaft 13 to which a gear 12 fixed, driven by
A gear 14 that drives the threaded cable 8 is fixed and a drive gear 15 is attached to the frame 20 that supports the motor 11 and the shaft 13, and a driven gear 16 that meshes with the drive gear 15 is pivotally supported. The driven gear 16 is rotated by a fixed pitch every rotation of the panel 3, and the driven gear 16 is set to rotate approximately 360 degrees while the panel 3 moves from the sliding release position B to the tilting release position C, for example. When the panel 3 reaches the fully closed position A, the recess 18 of the cam 17 that rotates integrally with the driven gear 16 operates the detection limit switch 19 to stop the motor 11. .

That is, to explain based on the electric circuit shown in FIG. rotates in one direction. This results in panel 3
slides or tilts from the fully closed position A, and the driven gear 16
The contact arm 19a of the limit switch 19, which had been engaged with the recess 18 of the cam 17 fixed to the cam 17, is pushed out, and the limit switch 19 is turned off.

When the switch 21 is turned OFF when the panel 3 reaches the sliding or tilting release positions B and C, or in the middle thereof, the motor 11 is stopped, and then the switch 2
If you operate 1 in the opposite direction and make contact with the other contact,
The motor 11 is started in the reverse direction to move the panel 3 in the closing direction, and when the panel 3 reaches the fully closed position A where the opening 2 is completely closed, the recess 1 of the cam 17
8 faces the contact arm 19a and turns on the limit switch 19, thereby turning on the relay 2.
6 to turn off the switch 27 and stop the motor 11.

Note that the resistor 28 slows down the motor 11, and after the panel 3 leaves the fully closed position A,
The limit switch 29 operated by the cam 30 provided on the driven gear 16 is turned on and short-circuited, causing the motor 11 to rotate at high speed.

In such a fully closed stop mechanism 10, the driven gear 1
If the drive gear 15 were to rotate at the same peripheral speed as the drive gear 15, it would have to be made to have a large diameter. Therefore, an intermittent drive system is adopted, in which the driven gear 16 is rotated by, for example, 24 degrees for each rotation of the drive gear 15. There is. However, one pitch of the driven gear 16 is a small angle, and therefore the length of the recess 18 of the cam 17 provided therein is also short.
The operating range of the limit switch 19 becomes narrower, and severe position adjustment is required.

Therefore, in the prior art, only when the panel 3 reaches the fully closed position A, the driven gear 16 is rotated by two pitches per rotation of the drive gear 15.

The configuration in which the driven gear 16 is driven intermittently one pitch at a time and is driven two pitches when the panel is fully closed is the first one.
As shown in Figures 1 to 13. That is, the driving gear 15 and the driven gear 16 are arranged in three directions in the width direction (axial direction).
The drive gear 15 is divided into parts (P1 to P3) (Q1 to Q3), and the drive gear 15 has two drive teeth 33 formed on both sides in the circumferential direction with a single tooth gap 32 across the entire width, and a middle part on both sides in the circumferential direction. 2 middle teeth 3 formed on P2
4, the driven gear 16 alternately has main teeth 35 that engage with the tooth gap 32 and short teeth 36 formed in the first portion Q1 between the main teeth 35, and the panel 3 is in the fully closed position A. The three medium long teeth 3 formed from the first portion Q1 to the second portion Q2 engage with the second medium teeth 34 to rotate the driven gear 16 twice the pitch when
7, and furthermore, each of the two central teeth 34 of the drive gear 15 has effective tooth surfaces on both sides, and
A middle tooth portion 34a having one side as an effective tooth surface is further formed in the circumferential direction of the middle tooth 34, and the main tooth 35 of the driven gear 16 has a full width length.

Therefore, when the drive gear 15 rotates once, one drive tooth 33 comes into contact with the short tooth 36 while the tooth gap 32 fits into the full-width main tooth 35, and the other drive tooth 33 comes into contact with the main tooth 35 and becomes driven. Gear 16 by 1 pitch (2
It rotates by the amount of teeth). Driven gear 1 shown in FIG.
The total number of teeth 35, 36, and 37 in 6 is 30, and 1
Because it meshes with two teeth in a pitch, its rotation angle is
It is 24°. Next, the panel 3 is in the fully closed position A.
When the drive gear 15 reaches the vicinity, the tooth gap 32 engages with the first medium long tooth 37a, and then the second,
Because of the presence of the third medium long teeth 37b and 37c, the medium tooth 34 and the medium tooth portion 3 of one effective tooth surface do not rotate idly.
4a meshes with the second and third medium-long teeth 37b and 37c, and the driven gear 16 is rotated by twice the pitch when the driving gear 151 rotates. As a result, the length of the recess 18 of the cam 17 can be made longer, and the range in which the panel is fully closed by the limit switch 19 can be widened.

(Problems to be Solved by the Invention) However, in the prior art, if there is a large error in the distance between the axes of the gears 15 and 16 and there is play,
Immediately after the tooth gap 32 fits into the main tooth 35 closest to the medium-long tooth 37, the medium tooth 34 comes into contact with the medium-long tooth 37, driving the driven gear 16 two pitches and causing the limit switch 19 to malfunction before the fully closed position. Sometimes I let it happen.
Also, even if gears 15 and 16 are properly engaged,
When closing from the sliding opening, the tooth gap 32 meshes with the teeth 37a on one side of the three medium long teeth 37, and when closing from the tilting opening, the tooth gap 32 meshes with the teeth 37c on the other side.
The fully closed detection position is shifted by two teeth, and even if the driven gear 16 is set to twice the pitch, the limit switch 1
9 position adjustment is severe and time consuming.

(Means for Solving the Problems) In the present invention, the main teeth 35 of the driven gear 16 are formed only in the third portion Q3 and arranged in a staggered manner with the short teeth 36,
By forming the protrusion 40 that can engage with the medium-long tooth 37 on the first portion P1 of the two drive teeth 33 of the drive gear 15, after the tooth gap 32 meshes with the main tooth 35 close to the medium-long tooth 37, the next The problems of the prior art can be solved by configuring the tooth gap 32 to fit into the central medium-long tooth 37b by engaging the protrusion 40 with the medium-long tooth 37a on one side, skipping over the short tooth 36. This is something that can be solved.

That is, the specific structure of the problem solving means of the present invention is characterized by
1, an opening/closing mechanism 7 that slides open and tilts the panel 3 that opens and closes the roof opening 2 from the fully closed position A using the power of the shaft 13; The fully closed stop mechanism 10 detects the fully closed position A of the motor 11 and stops the motor 11, and the fully closed stop mechanism 10 includes a drive gear 15 fixed to a shaft 13 and one It has a driven gear 16 that rotates by a fixed pitch every rotation, and a cam 17 provided on the driven gear 16 to operate a motor stop switch 19 when the panel 3 reaches the fully closed position A. The driving gear 15 and the driven gear 16 are divided into three parts in the width direction. Two central teeth 34 formed in the central portion P2 on both sides of the direction
The driven gear 16 has main teeth 35 that engage with the tooth gap 32 and short teeth 36 formed in the first portion Q1 between the main teeth 35 alternately, and when the panel 3 is in the fully closed position A. Three medium-long teeth 37 formed from the first portion Q1 to the second portion Q2 so as to mesh with the second medium teeth 34 and rotate the driven gear 16 by twice the pitch when the three medium-long teeth 37 reach the second portion Q1.
In the driving device for sliding and tilting a roof panel, the main tooth 35 of the driven gear 16 is formed only in the third portion Q3, and the two driving teeth 33 of the driving gear 15 have a central tooth formed in the first portion P1. A protrusion 40 that can engage with the long tooth 37 is formed, and the second medium tooth 34 has an effective tooth surface formed on the drive tooth 33 side.

(Function) When the panel 3 moves from the sliding open position B or the tilting open position C to the vicinity of the fully closed position A that closes the opening 2, the tooth gap 32 is engaged with the main tooth 35 near the medium long tooth 37. When the drive gear 15 makes about one rotation after the teeth are aligned, the protrusion 40 of one of the drive teeth 33a hits the first medium-long teeth 37a before hitting the short teeth 36 and starts driving the driven gear 16, and the tooth gap 32 becomes The other driving tooth 33b meshes with the central medium-long tooth 37b, and the medium tooth 34 fits into the third medium-long tooth 37c.
These mesh with each other to drive the driven gear 16 two pitches per 151 rotations of the drive gear. At this time, the recess 18 of the cam 17, which rotates integrally with the driven gear 16, faces the limit switch 19, and the motor 11 is stopped. The tooth gap 32 fits into the central long tooth 37b both when closing from sliding open and when closing from tilting open.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In FIGS. 1 to 6, reference numeral 41 denotes a drive unit fixed to the roof 1 (shown in FIG. 8), in which a motor 11 is fixed to the frame 20, and a shaft 13 driven by the power of the motor 11. A gear 14 meshing with the threaded cable 8 and a drive gear 15 are provided on the upper part of the shaft 13.

Reference numeral 16 denotes a driven gear that can mesh with the drive gear 15, and is integrally formed with a shaft portion 42. This shaft portion 42 is supported by the frame 20 so as to be rotatable around a vertical axis. , 30 are fitted or integrally molded.

19 and 29 are limit switches fixed on the frame 20. The limit switch 19 is for detecting the fully closed position of the panel 3, and its contact arm 19a is in contact with the cam 17, and the limit switch 19 is in contact with the recess 18.
It operates by facing the The limit switch 29 is for controlling the speed of the motor 11, and is operated by the cam 30 on its contact arm 29a.

The drive gear 15 is divided into three parts (P1 to P3) in the width direction (axial direction), and the first part P1
is formed to have a smaller diameter than the second and third portions P2 and P3. A tooth gap 32 spanning the entire width is formed at one position in the circumferential direction, two driving teeth 33 spanning the entire width are formed so as to sandwich this tooth gap 32, and a protrusion 40 is provided on the first portion P1 of each driving tooth 33. It is installed protruding in the direction.

Middle teeth 34 are formed on the outer periphery of the drive gear 15 before and after the two drive teeth 33 in the circumferential direction via grooves 43 . Each intermediate tooth 34 is located only in the second portion P2 and has an effective tooth surface only on the side facing the drive tooth 33. The effective tooth surface of the drive tooth 33 has the full width on the interdental 32 side, while the middle tooth 34 side has the first and second portions P.
1, is formed only at P2. The front and rear middle teeth 34 of this case are reduced by one tooth each compared to the prior art shown in FIG.

The driven gear 16 also has three parts Q1 to Q3 in the axial direction.
The main teeth 35 are formed only in the third portion Q3, and the short teeth 36 are formed only in the first portion Q1 and are located between the main teeth 35. The main teeth 35 and the short teeth 36 are arranged alternately in a staggered manner, and neither the main teeth 35 nor the short teeth 36 are present in the second portion Q2.

In addition to the main teeth 35 and short teeth 36, the driven gear 16 is provided with three medium-long teeth 37, and all the teeth are positioned at equal intervals in the circumferential direction, for example, at 12° intervals.
The three medium-long teeth 37 are located between the two short teeth 36, are formed in the first and second portions, and are not present in the third portion Q3.

The driving gear 15 and the driven gear 16 mesh once every 151 rotations of the driving gear 15, and the protrusion 40 of the leading drive tooth 33a engages with the short tooth 36, and the tooth gap 3
2 fits into the main tooth 35 immediately after the short tooth 36, and the driving tooth 33b on the trailing side meshes with this main tooth, rotating the driven gear 16 by two teeth, that is, one pitch (24 degrees). do.

When the leading drive tooth 33a is about to engage with the short tooth 36 immediately before the medium long tooth 37a, since the medium long tooth 37a exists in the first portion Q1 (if it is the main tooth 35, it will not fit in the first portion Q1). There is no tooth part and the protrusion 40 does not touch.), the protrusion 40 of the leading drive tooth 33a is the short tooth 36
Therefore, the tooth gap 32 engages with the middle long tooth 37b, the middle tooth 34 engages with the middle long tooth 37, and the driving gear 15 rotates one rotation to engage the driven gear. It meshes with the 4 teeth of No. 16 and rotates twice the pitch.

FIG. 7 shows a modification of the drive gear 15,
The first to third portions P1 to P3 of the drive gear 15' have the same diameter, and two drive teeth 33 and two middle teeth 34 are provided protruding from the outer peripheral surface. This driving gear 15' meshes with the driven gear 16 in the same way as in the previous embodiment.

In the above embodiment, the panel 3, the opening/closing mechanism 7, the electric circuit, etc. can use the conventional techniques shown in FIGS. 8 and 9 or other conventional techniques as they are, and the opening/closing operation of the panel 3 is substantially the same. The arrangement of the drive gear 15 and the shape of the shaft portion 42 of the driven gear 16 can also be made the same as in the prior art.

Furthermore, the present invention is not limited to the above-mentioned embodiments. For example, the cam 17 may be made to have approximately the same diameter as the driven gear 16, or a protrusion may be formed on the cam 17 instead of the recess 18, and the protrusion may be used to operate the limit switch 19. Various modifications can be made, such as by configuring it to operate.

(Effect of the invention) According to the invention described in detail above, the two drive teeth 33 of the drive gear 15 are formed with the projections 40 that can engage with the medium-long teeth 37 of the driven gear 16 in the first portion P1. Therefore, the main tooth 35 whose tooth gap 32 is close to the medium-long tooth 37
When the drive gear 15 rotates about one rotation after being fitted with the protrusion 40, the protrusion 40 engages with the medium long tooth 37 on one side before it engages with the next short tooth 36, and through this, the driven gear 1
6, and then the tooth gap 32 becomes the center medium long tooth 37b.
The medium teeth 34 mesh continuously with the medium long teeth 37 on the other side, and the driven gear 16 can be driven twice in pitch with one rotation of the drive gear 15, and can be driven in both forward and reverse directions. Since the tooth gap 32 fits with the central medium-long tooth 37b, the fully closed position A of forward and reverse rotation
The detection range of the fully closed position A of the panel 3 is widened, the position of the position detection means such as the recess 18 of the cam 17 and the limit switch 19 can be easily adjusted, and the protrusion 40 can be pushed against the drive tooth 33. By forming the main teeth 35 to a length that exists only in the third portion Q3 of the driven gear 16, the protrusion 40
Since the drive gear 15 does not have teeth before and after the second medium tooth 34, the medium long tooth 37 does not come into contact with the main tooth 35 before reaching the fully closed position A as in the prior art.
There is no possibility of a malfunction in which the motor 11 is stopped due to engagement with the motor 11, and accurate panel opening/closing operations can be performed at all times.
