Description

  The present invention relates to an electric sliding door system.

  When a sliding door of a vehicle is fully opened, the locking mechanism attached to the sliding door engages with a striker provided on the vehicle main body (the vehicle main body excluding the sliding door). The door is fixed to the vehicle body. In this way, even when the vehicle is stopped on a slope, the sliding door is prevented from moving in the closing direction due to its own weight, and the fully open state of the sliding door is maintained.

  Further, when the sliding door is moved in the opening direction, a motor provided in the vehicle rotates, whereby a drum connected to the motor rotates, and the drum is wound around a cable connected to the sliding door. In this way, the slide door moves in the opening direction (see, for example, Patent Document 1).

  Further, when the slide door is moved to the fully open position, first, the lock mechanism attached to the slide door is engaged with the striker, so that the slide door is fixed to the vehicle body. Thereafter, it is detected that the cable connected to the slide door cannot be further wound by the drum, and the control device stops the rotation of the motor after a predetermined period of time (for example, after 1 to 2 seconds).

  Hereinafter, an embodiment of the present invention (hereinafter simply referred to as the present embodiment) will be described with reference to the drawings. In addition, about the member which has the same reference number as the member already demonstrated in description of this embodiment, the description is abbreviate | omitted for convenience of explanation. Moreover, the dimension of each member shown by this drawing may differ from the actual dimension of each member for convenience of explanation.

  The outline of the electric sliding door system 2 will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic diagram illustrating a part of a side surface of a vehicle 1 (for example, an automobile) including an electric sliding door system 2 according to the present embodiment. FIG. 2 shows a block diagram of the electric sliding door system 2. As shown in FIGS. 1 and 2, the electric slide door system 2 includes a slide door 5, a lock mechanism 3 (holding mechanism), a drive mechanism 20, a control device 21, cables 13A and 13B, and a switch 4 ( Detection means), an outer handle 11, and an inner handle (not shown). The sliding door 5 is configured to open and close the entrance 9 provided on the side of the vehicle 1 by driving a motor 22 of the drive mechanism 20. In particular, the slide door 5 is configured to open and close the entrance 9 by moving in the vehicle longitudinal direction along the guide rails 6, 7, and 8.

  The lock mechanism 3 is configured to hold the slide door 5 in a fully opened state, and is attached to a predetermined position (for example, in the vicinity of the guide rail 8) of the slide door 5. In FIG. 1, the slide door 5 is in a fully open state, and the lock mechanism 3 attached to the slide door 5 is engaged with a striker 50 (see FIG. 7) provided in the vehicle 1. It is fixed to the vehicle main body (vehicle main body excluding the slide door 5). Thus, by providing the lock mechanism 3, the sliding door 5 moves in the closing direction (the direction opposite to the direction of the arrow shown in the figure) by its own weight when the vehicle 1 is stopped on a slope. Is prevented, and the fully open state of the slide door 5 is maintained. The specific configuration of the lock mechanism 3 will be described later.

  As shown in FIG. 2, the drive mechanism 20 transmits or blocks the motor 22, the speed reduction mechanism 23 configured to reduce the rotational speed of the motor 22, and the rotational torque output from the speed reduction mechanism 23. The electromagnetic clutch 24 is configured, and the drum 25 is configured to wind the cables 13A and 13B. The control device 21 is configured to control driving of the motor 22 and the electromagnetic clutch 24, and is configured by an electronic control unit (ECU). The electronic control unit includes a processor such as a CPU (Central Processing Unit), a ROM (Read Only Memory) in which various drive control programs are stored, and a RAM (Random Access Memory) in which various drive control data are temporarily stored. It is comprised by. The processor is configured to develop a program designated from various drive control programs stored in the ROM on the RAM and execute various processes in cooperation with the RAM. The control device 21 is configured to drive and control the motor 22 in accordance with an input signal generated by operating the outer handle 11 (or the inner handle). Moreover, the control apparatus 21 is comprised so that rotation of the motor 22 may be stopped according to the detection signal output from the switch 4 (refer FIG. 3 or later).

  The cable 13 </ b> A is wound around the drum 25 via the guide pulley 17 and is connected to the slide door 5 via a slider 15 that slides on the guide rail 7. The cable 13B is wound around the drum 25 via the guide pulley 16 and is connected to the slide door 5 via the slider 15. When the slide door 5 is moved in the opening direction (the direction of the arrow in the figure), the drum 25 is rotated via the speed reduction mechanism 23 and the electromagnetic clutch 24 by the motor 22 rotating (forward rotation). Then, when the drum 25 winds the cable 13A connected to the slider 15, the slide door 5 coupled to the slider 15 moves in the opening direction. On the other hand, when the slide door 5 is moved in the closing direction, the drum 22 is rotated in the reverse direction by the motor 22 rotating in the reverse direction, and the drum 25 is wound up by the cable 13B connected to the slider 15. Moves in the closing direction.

  The switch 4 is configured to detect that the slide door 5 is held by the lock mechanism 3, and is provided in the lock mechanism 3. The installation location of the switch 4 is not limited to the lock mechanism 3, and the switch 4 may be disposed at a predetermined location of the vehicle 1. When the switch 4 detects that the slide door 5 is held by the lock mechanism 3, the switch 4 generates a detection signal and transmits the detection signal to the control device 21. Thereafter, the control device 21 stops the rotation of the motor 22 according to the detection signal. In this way, the rotation of the drum 25 is stopped.

  Thus, according to the present embodiment, by providing the switch 4, it can be detected that the slide door 5 is held by the lock mechanism 3 in the fully opened state. Therefore, by providing a detection signal indicating that the slide door 5 is held in the fully open state to the control device 21 that drives and controls the motor 22, the slide door 5 is immediately after the fully open state of the slide door 5 is detected. The rotation of the drum 25 that drives can be stopped. Therefore, when the rotation of the drum 25 is stopped, since a large load is not applied to the lock mechanism 3 and the cables 13A and 13B that hold the slide door 5 in the fully opened state, the electric slide door system 2 with improved durability is provided. be able to.

  Next, specific configurations of the lock mechanism 3 and the switch 4 will be described with reference to FIGS. FIG. 3 is a top view showing the lock mechanism 3. FIG. 4 shows an exploded perspective view of the lock mechanism 3. Fig.5 (a) is AA sectional drawing of the locking mechanism 3 shown in FIG. FIG.5 (b) is BB sectional drawing of the locking mechanism 3 shown in FIG. FIG.5 (c) is CC sectional drawing of the locking mechanism 3 shown in FIG. For convenience of explanation, the exploded perspective view of the lock mechanism 3 shown in FIG. 4 is rotated 180 degrees from the top view of the lock mechanism 3 shown in FIG.

  As shown in FIGS. 3 to 5, the lock mechanism 3 includes an upper plate 31, a lower plate 32, a hook 33, a ratchet 34, pins 35 and 36, springs 37 and 38, and an unlocking cable 39. With. The switch 4 is provided in the lock mechanism 3.

  The hook 33 is disposed on the upper plate 31 and is rotatably fixed to the upper plate 31 by pins 36. Further, the hook 33 is urged clockwise by a spring 38 when viewed from above the lock mechanism 3. The upper plate 31 is disposed above the lower plate 32. Further, it is assumed that the vertical direction of the lock mechanism 3 and the vertical direction of the vehicle 1 shown in FIG. In the following description, the “clockwise direction” is a clockwise direction when viewed from above the lock mechanism 3. On the other hand, the “counterclockwise direction” is a counterclockwise direction when viewed from above the lock mechanism 3. The hook 33 includes an accommodating portion 33a that accommodates the striker 50 (see FIG. 7), and an engaging portion 33b that engages with the ratchet 34 (specifically, the engaging portion 34b of the ratchet 34). The lock mechanism 3 is configured to hold the slide door 5 in a fully opened state by engaging the hook 33 with the striker 50 (specifically, the striker 50 is accommodated in the accommodating portion 33a).

  The ratchet 34 is rotatably attached to the upper plate 31 by pins 35. The ratchet 34 is urged clockwise by a spring 37. The ratchet 34 includes an engaging portion 34b that engages with the engaging portion 33b of the hook 33, and an arm portion 34a that rotates with the rotation of the ratchet 34 and has a larger turning locus than the engaging portion 34b. . The arm portion 34 a has a tip portion 34 c that contacts the lever 41 of the switch 4. The ratchet 34 is configured to engage the hook 33 when the hook 33 engages the striker 50.

  The pins 35 and 36 fix the upper plate 31 and the lower plate 32 to each other. When the outer handle 11 (or the inner handle) is operated, the lock release cable 39 rotates the ratchet 34 counterclockwise to release the engagement between the ratchet 34 and the hook 33. As a result, the engagement between the hook 33 and the striker 50 is released. Further, a part of the arm portion 34 a of the ratchet 34 overlaps with the unlocking cable 39 in the vertical direction before the hook 33 is engaged with the striker 50. Thus, when the arm part 34a rotates, the arm part 34a is prevented from being caught by the unlocking cable 39.

  The switch 4 is fixed to the upper plate 31 by a screw 44 (see FIG. 5C). The switch 4 includes a lever 41 formed in a leaf spring shape that exhibits elastic force, and a switch button 42. The detection signal generated by the switch 4 is transmitted to the control device 21 through the cable 43. By disposing the switch 4 in the vicinity of the lock release cable 39, the cable 43 can be prevented from interfering with the components of the lock mechanism 3. Further, since the switch 4 is disposed on the upper plate 31, even when a water droplet adheres to the switch 4, the water droplet falls on the lower plate 32 due to its own weight, so that it is possible to prevent water from collecting in the peripheral area of the switch 4. Can do.

  Next, the operation of the lock mechanism 3 before and after the hook 33 engages with the striker 50 will be described with reference to FIGS. FIG. 6 shows the lock mechanism 3 in a state before the hook 33 engages with the striker 50 (hereinafter simply referred to as a non-engaged state), and FIG. 7 shows a state after the hook 33 engages with the striker 50. The lock mechanism 3 in the following (hereinafter simply referred to as an engaged state) is shown. For convenience of explanation, the entire striker 50 is not shown, and only a cross section of the striker 50 is shown.

  In the disengaged state shown in FIG. 6, the hook 33 is urged clockwise by the spring 38 and the ratchet 34 is urged clockwise by the spring 37. For this reason, the ratchet 34 and the hook 33 are kept stationary while the surface 33b1 of the engaging portion 33b of the hook 33 and the surface 34b1 of the engaging portion 34b of the ratchet 34 are in contact with each other.

  Furthermore, in the non-engaged state, the tip end portion 34 c of the arm portion 34 a presses the lever 41 of the switch 4. As described above, the distal end portion 34 c pushes the switch button 42 via the lever 41. When the switch button 42 is pressed, the switch 4 does not generate a detection signal indicating that the slide door 5 is held by the lock mechanism 3.

  Next, the engagement state shown in FIG. 7 will be described. When the sliding door 5 that moves in the opening direction shown in FIG. 1 is fully opened, the hook 33 of the locking mechanism 3 attached to the sliding door 5 comes into contact with the striker 50 fixed to the vehicle 1, thereby It rotates counterclockwise around the center. As the hook 33 rotates, the striker 50 is accommodated in the accommodating portion 33a of the hook 33, so that the hook 33 and the striker 50 are engaged. At this time, with the rotation of the engaging portion 33b of the hook 33, the contact state between the surface 33b1 of the engaging portion 33b and the surface 34b1 of the engaging portion 34b is eliminated, so that the ratchet 34 moves the pin 35 inward. Rotate in a clockwise direction. As a result, the engaging portion 34 b of the ratchet 34 is engaged with the engaging portion 33 b of the hook 33. Thus, when the hook 33 engages with the striker 50, the ratchet 34 rotates in a direction (clockwise direction) in which it engages with the hook 33.

  Further, when the ratchet 34 rotates in the clockwise direction, the tip end portion 34 c of the arm portion 34 a releases the switch button 42 of the switch 4. Specifically, when the distal end portion 34 c is separated from the lever 41 of the switch 4, the switch button 42 is released by the lever 41 that exhibits elasticity returning to the initial position. When the pressing of the switch button 42 is released, the switch 4 generates a detection signal indicating that the slide door 5 is held by the lock mechanism 3. The generated detection signal is transmitted to the control device 21 via the cable 43. The control device 21 stops the rotation of the motor 22 according to the detection signal. In this way, the rotation of the drum 25 is stopped.

  According to the present embodiment, the switch 4 is configured to detect that the slide door 5 is held by the lock mechanism 3 by detecting that the distal end portion 34 c has released the switch button 42. In this way, it is possible to detect that the slide door 5 is held by the lock mechanism 3 with a relatively simple structure.

  In the present embodiment, the distal end portion 34c presses the lever 41 in the disengaged state shown in FIG. 6, and the distal end portion 34c moves away from the lever 41 in the engaged state shown in FIG. According to this configuration, the lever 41 can be prevented from being broken by the rotation of the arm portion 34a.

  According to the present embodiment, the switch 4 detects that the distal end portion 34c has released the switch button 42, but it can also be said that the switch 4 detects the rotation of the arm portion 34a. Further, it can be said that the switch 4 detects the rotation of the ratchet 34. Further, it can be said that the switch 4 detects that the hook 33 is engaged with the striker 50.

  In the present embodiment, the switch 4 is used as detection means for detecting that the slide door 5 is held by the lock mechanism 3, but the present embodiment is not limited to this. For example, a sensor (detection means) configured to detect that the hook 33 is engaged with the striker 50 may be provided instead of the switch 4. In this case, it can be detected that the slide door 5 is held by the lock mechanism 3 by detecting that the hook 33 is engaged with the striker 50.

  A sensor configured to detect the rotation of the ratchet 34 may be provided instead of the switch 4. In this case, it is possible to detect that the slide door 5 is held by the lock mechanism 3 by detecting the rotation of the ratchet 34. In particular, the ratchet 34 remains stationary until the hook 33 engages with the striker 50, so that the sliding door 5 is held by the lock mechanism 3 by detecting the rotation of the ratchet 34. Can be accurately detected.

  A sensor configured to detect the rotation of the arm portion 34 a may be provided instead of the switch 4. In this case, it is possible to more easily detect that the slide door 5 is held by the lock mechanism 3 by detecting the rotation of the arm portion 34a having a larger rotation locus than the engaging portion 34b.

  Although the embodiment of the present invention has been described above, it goes without saying that the technical scope of the present invention should not be construed in a limited manner by the description of this embodiment. This embodiment is merely an example, and it is understood by those skilled in the art that various embodiments can be changed within the scope of the invention described in the claims. Thus, the technical scope of the present invention should be determined based on the scope of the invention described in the claims and the equivalent scope thereof.
