Description

The present invention relates to an electric sliding door system.

In a vehicle slide door, when the slide door is fully opened, a lock mechanism attached to the slide door engages with a striker provided in the vehicle body (vehicle body excluding the slide door) to allow the slide door to slide. 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 opened state of the sliding door is maintained.

Further, when the slide door is moved in the opening direction, the motor provided in the vehicle is rotated, whereby the drum connected to the motor is rotated and the drum winds up the cable connected to the slide 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. After that, it is detected that the cable connected to the slide door cannot be wound by the drum any more, and the control device stops the rotation operation of the motor after a predetermined period of time (for example, 1 to 2 seconds).

An outline of the electric sliding door system 2 will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic view showing a part of a side surface of a vehicle 1 (for example, an automobile) including an electric slide door system 2 according to this 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 slide door 5 is configured to open and close an entrance/exit 9 provided on a side portion of the vehicle 1 by driving a motor 22 of a drive mechanism 20. In particular, the slide door 5 is configured to open and close the entrance/exit 9 by moving in the vehicle front-rear 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 of the slide door 5 (for example, near the guide rail 8). In FIG. 1, the slide door 5 is in a fully opened state, and the lock mechanism 3 attached to the slide door 5 engages with the striker 50 (see FIG. 7) provided in the vehicle 1 to cause the slide door 5 to move. It is fixed to the vehicle body (vehicle body excluding the slide door 5). By providing the lock mechanism 3 in this way, when the vehicle 1 is stopped on a slope, 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. Is prevented, and the fully opened state of the slide door 5 is maintained. The specific structure of the lock mechanism 3 will be described later.

The drive mechanism 20, as shown in FIG. 2, transmits or cuts off the motor 22, the speed reducing mechanism 23 configured to reduce the rotational speed of the motor 22, and the rotational torque output from the speed reducing mechanism 23. It has an electromagnetic clutch 24 configured and a drum 25 configured to wind up 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) storing various drive control programs, and a RAM (Random Access Memory) temporarily storing various drive control data. It is composed 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 response to an input signal generated by operating the outer handle 11 (or the inner handle). Further, the control device 21 is configured to stop the rotation of the motor 22 in response to a detection signal output from the switch 4 (see FIG. 3 and subsequent figures).

The cable 13A is wound around the drum 25 via the guide pulley 17, and is also connected to the slide door 5 via the slider 15 that slides on the guide rail 7. The cable 13B is wound around the drum 25 via the guide pulley 16 and 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 drawing), the motor 22 rotates (forward rotation), and the drum 25 rotates via the speed reduction mechanism 23 and the electromagnetic clutch 24. Then, the drum 25 winds up the cable 13A connected to the slider 15, whereby the slide door 5 connected 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 motor 22 rotates in the reverse direction, the drum 25 rotates in the reverse direction, and the drum 25 winds the cable 13B connected to the slider 15 to rotate the slide door 5 in the closing direction. 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. Then, 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.

As described above, according to the present embodiment, by providing the switch 4, it is possible to detect that the slide door 5 is held by the lock mechanism 3 in the fully opened state. Therefore, by providing the control device 21 that controls the drive of the motor 22 with a detection signal indicating that the slide door 5 is held in the fully opened state, the slide door 5 is immediately after the fully opened state is detected. It is possible to stop the rotation of the drum 25 that drives the. Therefore, when the rotation of the drum 25 is stopped, 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, so that the electric slide door system 2 having 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. 5A is a cross-sectional view taken along the line AA of the lock mechanism 3 shown in FIG. FIG. 5B is a BB cross-sectional view of the lock mechanism 3 shown in FIG. FIG. 5C is a sectional view taken along line CC of the lock 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 on the lock mechanism 3.

The hook 33 is arranged on the upper plate 31 and is rotatably fixed to the upper plate 31 by a pin 36. Further, the hook 33 is biased clockwise by a spring 38 when viewed from above the lock mechanism 3. The upper plate 31 is arranged 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 the clockwise direction when viewed from above the lock mechanism 3. On the other hand, the “counterclockwise direction” is the counterclockwise direction when viewed from above the lock mechanism 3. The hook 33 has 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 the hook 33 engaging the striker 50 (specifically, the striker 50 being housed in the housing portion 33a).

The ratchet 34 is rotatably attached to the upper plate 31 by a pin 35. The ratchet 34 is biased clockwise by a spring 37. The ratchet 34 has an engagement portion 34b that engages with the engagement portion 33b of the hook 33, and an arm portion 34a that rotates with the rotation of the ratchet 34 and that has a larger rotation locus than the engagement portion 34b. .. The arm portion 34 a has a tip portion 34 c that comes into contact with 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 releasing 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. In addition, a part of the arm portion 34a of the ratchet 34 vertically overlaps with the unlocking cable 39 before the hook 33 is engaged with the striker 50. In this way, the arm portion 34a is prevented from being caught by the lock release cable 39 when the arm portion 34a rotates.

The switch 4 is fixed to the upper plate 31 by a screw 44 (see FIG. 5(c)). The switch 4 has a lever 41 formed in the shape of a leaf spring that exhibits elastic force, and a switch button 42. The detection signal generated by the switch 4 is transmitted to the control device 21 via the cable 43. By disposing the switch 4 near the lock releasing cable 39, it is possible to suppress the cable 43 from interfering with the components of the lock mechanism 3. Further, since the switch 4 is arranged on the upper plate 31, even if water droplets adhere to the switch 4, the water droplets fall to the lower plate 32 due to its own weight, so that water is prevented from collecting in the peripheral area of the switch 4. You can

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-engagement state), and FIG. 7 shows a state after the hook 33 engages with the striker 50. The lock mechanism 3 in (hereinafter, simply referred to as an engaged state) is shown. For convenience of description, the striker 50 is not shown in its entirety, but only the cross section of the striker 50 is shown.

In the disengaged state shown in FIG. 6, the hook 33 is biased clockwise by the spring 38, and the ratchet 34 is biased clockwise by the spring 37. For this reason, the ratchet 34 and the hook 33 remain stationary in a state where 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 portion 34c of the arm portion 34a presses the lever 41 of the switch 4. Thus, the tip portion 34c 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 slide door 5 moving in the opening direction shown in FIG. 1 is in the fully open state, the hook 33 of the lock mechanism 3 attached to the slide door 5 comes into contact with the striker 50 fixed to the vehicle 1 to cause the pin 36 to move. Rotate counterclockwise around. As the hook 33 rotates, the striker 50 is housed in the housing portion 33a of the hook 33, so that the hook 33 and the striker 50 engage with each other. At this time, as the engaging portion 33b of the hook 33 is rotated, the contact state between the surface 33b1 of the engaging portion 33b and the surface 34b1 of the engaging portion 34b is released, so that the ratchet 34 inserts the pin 35 into the center. Carefully rotate in the clockwise direction. As a result, the engagement portion 34b of the ratchet 34 engages with the engagement portion 33b of the hook 33. In this way, when the hook 33 engages with the striker 50, the ratchet 34 rotates in the direction in which the hook 33 engages (clockwise direction).

Further, when the ratchet 34 rotates clockwise, the tip portion 34c of the arm portion 34a releases the switch button 42 of the switch 4. Specifically, when the tip portion 34c separates from the lever 41 of the switch 4, the lever 41 exhibiting an elastic force returns to the initial position to release the switch button 42. When the depression 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 tip portion 34c 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.

Further, in the present embodiment, the tip portion 34c presses the lever 41 in the non-engaged state shown in FIG. 6, and the tip portion 34c separates from the lever 41 in the engaged state shown in FIG. With this configuration, it is possible to prevent the lever 41 from being broken by the rotation of the arm portion 34a.

According to the present embodiment, the switch 4 detects that the tip portion 34c has released the switch button 42, but it can be said that the switch 4 also 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.

Further, in the present embodiment, the switch 4 is used as a detection unit that detects 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, by detecting that the hook 33 is engaged with the striker 50, it is possible to detect that the slide door 5 is held by the lock mechanism 3.

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, since the ratchet 34 remains stationary until the hook 33 engages with the striker 50, 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. Can be accurately detected.

Further, a sensor configured to detect the rotation of the arm portion 34a 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 engagement portion 34b.

Although the embodiments of the present invention have been described above, it goes without saying that the technical scope of the present invention should not be limitedly interpreted by the description of the present embodiments. It is understood by those skilled in the art that the present embodiment is merely an example, and various modifications can be made 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.
