[0003] Existing technical documents

[0004] Patent documents

[0005] Patent document 1: Japanese Patent Application Publication No. 2008-144402.

[0006] Patent document 2: Japanese Patent Application Publication No. 2012-72645.

[0007] In recent years, with the continuous advancement of electronic control in vehicles, there has been a demand to eliminate interior door handles. Furthermore, previous control devices, with their numerous and complex rocker arms, are no longer suitable for current vehicles.

[0008] Furthermore, emergency unlock handles are often directly integrated into the control unit, limiting the installation location of the control unit and thus affecting the design freedom of the door. Also, to prevent accidental operation, a cover is usually installed on the inside of the door to obscure the emergency unlock handle, which also affects the aesthetics of the vehicle's interior. Utility Model Content

[0009] The purpose of this invention is to provide a door control device that can reduce the number of rocker arms while ensuring functionality.

[0010] One embodiment of the vehicle door control device of this utility model includes: a first rocker arm having a first elongated hole and a second elongated hole; a second rocker arm connected to the vehicle's outer handle and a locking mechanism via pull cables, and having a first abutment portion, wherein the outer handle or the locking mechanism can pull the second rocker arm to rotate via the pull cables; a third rocker arm connected to an emergency release device and having a second abutment portion, wherein the emergency release device can pull the third rocker arm to rotate; a first control lever having a first sliding groove at one end, wherein a first idler pin passes sequentially through the first elongated hole and the first sliding groove; and a second control lever having a second sliding groove at one end, wherein a second idler pin passes sequentially through the second elongated hole and the second sliding groove, wherein the first idler pin can be rotated by... The first rocker arm can move between a first unlocked position and a first locked position in the first elongated hole. In the first unlocked position, the first abutment abuts against the first idler pin, so that the first rocker arm can rotate with the rotation of the second rocker arm. In the first locked position, the first idler pin does not abut against the first abutment, so that the first rocker arm cannot rotate with the rotation of the second rocker arm. The second idler pin can move between a second unlocked position and a second locked position in the second elongated hole. In the second unlocked position, the second abutment abuts against the second idler pin, so that the first rocker arm can rotate with the rotation of the third rocker arm. In the second locked position, the second idler pin does not abut against the second abutment, so that the first rocker arm cannot rotate with the rotation of the third rocker arm.

[0011] Based on the above structure, by connecting both the first and second control levers to the first rocker arm, and connecting both the outer handle cable and the release cable to the second rocker arm, the number of rocker arms can be reduced. This simplifies the device structure and reduces manufacturing costs while maintaining the functionality of the door control device.

[0012] In addition, in the above-described manner, it is preferable to further include a first electric arm driven by a motor, which is rotatably connected to the other end of the first control lever, so that the first electric arm can drive the first control lever to rotate.

[0013] Based on the above structure, the first control lever can be reliably controlled electronically.

[0014] In addition, in the above method, it is preferred to also include a second electric arm driven by a motor, which is rotatably connected to the other end of the second control lever, so that the second electric arm can drive the second control lever to rotate.

[0015] According to the above structure, since a second control lever is provided to be driven by a second electric arm, the emergency release device can be locked through simple operation or automatically by the vehicle's ECU. Therefore, compared to covering the emergency release device with a cover or other means to prevent accidental operation, it is not necessary to hide the emergency release device, thus facilitating its use by occupants.

[0016] Furthermore, in the event of a vehicle collision, a signal can be sent to the motor of the second electric arm, causing it to automatically move the second idle pin to the second unlocked position. This ensures safety during a vehicle collision.

[0017] Furthermore, since the rotation of the second and third rocker arms is independent of each other, and the first and second control levers are controlled by the first and second electric arms respectively, different locking / unlocking logics can be implemented by designing the timing of the control signals sent from inside the vehicle to the first and second electric arms, thus meeting the needs of different vehicle manufacturers.

[0018] In addition, in the above-described manner, it is preferable that the third rocker arm is connected to the emergency release device via a pull cable.

[0019] Based on the above structure, compared with the case where the emergency release device is directly installed on the door control device, the emergency release device can be placed in a location that is easy for passengers to find, which can further improve the user experience and design freedom.

[0020] In addition, in the above-described manner, it is preferable that the emergency release device is a handle-shaped part exposed on the interior side of the vehicle door.

[0021] Based on the above structure, the emergency release device can be used as an interior handle even when there is no emergency. Therefore, the interior handle can be eliminated, thereby eliminating the rocker arm used to connect to it and further reducing manufacturing costs. Furthermore, by eliminating the interior handle, the door control unit can be entirely housed within the door trim and not exposed to the interior. This allows for a more consistent door trim design, improving the aesthetics and design freedom of the interior.

[0022] In addition, in the above-described manner, it is preferable to also include a control handle, which is exposed on the interior side of the vehicle door and is rotatably connected to the other end of the second control lever via a pull cable or linkage, so that when the control handle is manually operated, it can drive the second control lever to rotate.

[0023] Based on this structure, the functions of child care institutions can be realized through manually controlled handles.

[0024] In addition, in the above method, it is preferred that a base plate and a return spring are also provided. The first rocker arm, the second rocker arm, and the third rocker arm are rotatably mounted on the base plate via a shaft. One end of the return spring is connected to the second rocker arm, and the other end is connected to the base plate. When the operation of the second rocker arm by the outer handle or the locking mechanism ends, the return spring causes the second rocker arm to return to its original position.

[0025] This structure allows for improved ease of use of the door control device through a simple design. Attached Figure Description

[0035] Hereinafter, a preferred embodiment of the door control device will be described with reference to the accompanying drawings. In this embodiment, the door is a sliding door of the vehicle, and the opening is the door opening. Furthermore, when terms indicating direction such as "up," "down," "left," and "right" are used in the embodiment, they refer to the directions shown in the drawings and are not intended to limit the actual direction of use of the door control device.

[0036] (Structure of the control device)

[0037] First, refer to Figure 1 , Figure 2 The specific structure of the door control device will be explained. Figure 1 This is a diagram indicating that the door control device is in the unlocked state.

[0038] like Figure 1 , Figure 2 As shown, the door control device includes: a base plate 10, a first rocker arm 1, a second rocker arm 2, a third rocker arm 3, a first control lever 4, a second control lever 5, a first electric arm 8, and a second electric arm 9. The first rocker arm 1, the second rocker arm 2, and the third rocker arm 3 are rotatably mounted on the base plate 10 via a shaft 11.

[0039] The first rocker arm 1 is elongated, having a first elongated hole 1a and a second elongated hole 1b. The first elongated hole 1a is located at one end along the length of the first rocker arm 1 and extends along the length of the first rocker arm 1. The second elongated hole 1b extends from a portion near the middle along the length of the first rocker arm 1 in a direction intersecting the length direction (obliquely upward in this embodiment). Three cable connection holes 1c are provided at the other end along the length of the first rocker arm 1 for operating, via cable, a sliding door (not shown) with features such as a front lock, an electric rear lock, and a fully open limit lock.

[0040] The first control lever 4 is mounted on the base plate 10. A first sliding groove 4a is provided at one end of the first control lever 4. A first idler pin 6 passes through the first elongated hole 1a of the first rocker arm 1 and the first sliding groove 4a in sequence, so that the first elongated hole 1a is rotatably connected to the first control lever 4 via the first idler pin 6. The first electric arm 8 is driven by a motor and is rotatably connected to the other end of the first control lever 4, so that the first electric arm 8 can drive the first control lever 4 to rotate.

[0041] The second control lever 5 is mounted on the base plate 10. A second sliding groove 5a is provided at one end of the second control lever 5. A second idler pin 7 passes sequentially through the second elongated hole 1b of the first rocker arm 1 and the second sliding groove 5a, thereby allowing the second elongated hole 1b to be rotatably connected to the second control lever 5 via the second idler pin 7. The second electric arm 9 is driven by a motor and is rotatably connected to the other end of the second control lever 5, thus enabling the second electric arm 9 to drive the second control lever 5 to rotate. The second control lever 5 and the second electric arm 9 constitute the child care mechanism in this embodiment.

[0042] The second rocker arm 2 is connected to the vehicle's outer handle (not shown) and electric lock (locking mechanism) via pull cables. The outer handle or electric lock can rotate the second rocker arm 2 by pulling the pull cables. Specifically, the second rocker arm 2 has two slide grooves 2b, in which two pull cable connectors 2c are inserted respectively. The two pull cable connectors 2c are connected to the outer handle and the electric lock via the outer handle pull cable and the release pull cable, respectively.

[0043] The door control device is also equipped with a return spring 12 and a torsion spring 13. One end of the return spring 12 is connected to the second rocker arm 2, and the other end is connected to the base plate 10. The torsion spring 13 is disposed on the shaft 11 and abuts against the first rocker arm 1 through an extended portion extending radially outward from the shaft 11.

[0044] The third rocker arm 3 has a cable mounting part 3b for mounting a pull cable. The third rocker arm 3 is connected to an emergency release device (not shown) via a pull cable, which can pull the third rocker arm 3 to rotate. In this embodiment, the emergency release device is a handle-shaped part exposed on the interior side of the door. In emergency situations such as vehicle collisions or power outages, the sliding door can be opened by the occupant controlling the emergency release device. Detailed operation of the emergency release device will be described later.

[0045] The second rocker arm 2 is provided with a first abutment portion 2a. When the first control lever 4 rotates, it causes the first idler pin 6 to be in the first unlocked position in the first elongated hole portion 1a (see reference). Figure 1 ) and the first locking position (refer to) Figure 3 The first rocker arm 1 moves between the two rocker arms. In the first unlocked position, the first abutting part 2a abuts against the first idle pin 6, so that the first rocker arm 1 can rotate with the rotation of the second rocker arm 2. In the first locked position, the first idle pin 6 does not abut against the first abutting part 2a, so that the first rocker arm 1 cannot rotate with the rotation of the second rocker arm 2.

[0046] The third rocker arm 3 has a protrusion 3a. When the second control lever 5 rotates, it moves the second idler pin 7 to the second unlocked position in the second elongated hole 1b (see reference). Figure 1 ) and second locking position (refer to Figure 6 In the second unlocked position, the lower surface (second abutment) of the protrusion 3a abuts against the second idler pin 7, so that the first rocker arm 1 can rotate with the rotation of the third rocker arm 3. In the second locked position, the second idler pin 7 does not abut against the lower surface of the protrusion 3a, so that the first rocker arm 1 cannot rotate with the rotation of the third rocker arm 3.

[0047] (Lock function)

[0048] The following is for reference Figure 1 , 3 The locking function of the door control device is explained.

[0049] When the vehicle is in motion or stopped and no key is detected, the front lock and electric rear lock of the sliding door must be locked.

[0050] In this case, the vehicle's ECU or similar device sends a control signal to the motor of the first electric arm 8, thereby controlling the first electric arm 8 to move from... Figure 1 The state shown is a counterclockwise rotation. Consequently, the first electric arm 8 drives the first control lever 4 to rotate clockwise, thereby causing the first control lever 4 to move the first idler pin 6 upwards in the first elongated hole 1a via the first sliding groove 4a. Thus, the first idler pin 6 moves from... Figure 1 The first unlock position in the game is moved to Figure 3 The first locking position is such that the first idle pin 6 does not abut against the first abutting part 2a of the second rocker arm 2. Therefore, even if the outer handle pulls the second rocker arm 2 via the outer handle cable or sends a signal to the electric lock via the unlock button, causing the electric lock to pull the second rocker arm 2 via the release cable, the second rocker arm 2 cannot drive the first rocker arm 1 to rotate, and thus cannot control the front lock and electric rear lock of the sliding door to unlock via the first rocker arm 1.

[0051] (Unlocking function, sliding door opening and closing function)

[0052] The following is for reference Figure 1 , 3 4. Explain the locking function of the door control device.

[0053] In situations where the sliding door needs to be opened or closed, such as when the vehicle is stationary, the vehicle's ECU sends a control signal to the motor of the first electric arm 8, thereby controlling the first electric arm 8 to move from... Figure 3 The position shown is rotated clockwise. This causes the first electric arm 8 to rotate the first control lever 4 counterclockwise, thereby causing the first control lever 4 to move the first idler pin 6 downwards in the first elongated hole 1a via the first sliding groove 4a. Thus, the first idler pin 6 moves from... Figure 3 The first locked position in the middle is moved to Figure 1 The first unlocking position is reached, so that the first idle pin 6 abuts against the first abutting part 2a of the second rocker arm 2.

[0054] Next, as Figure 4As shown, the external handle or electric lock pulls the pull cable connector 2c via the external handle pull cable or release pull cable, causing the second rocker arm 2 to rotate to the left via the pull cable connector 2c. In this way, the second rocker arm 2 pushes the first idler pin 6 in the first elongated hole 1a of the first rocker arm 1 via the first abutment part 2a, thereby pushing the first rocker arm 1 to rotate around the axis 11 via the first idler pin 6. Thus, the first rocker arm 1 operates the front lock and electric rear lock of the sliding door via the pull cable, causing the sliding door to open and close. At this time, the return spring 12 is stretched as the second rocker arm 2 rotates, and the torsion spring 13 is tightened by the push of the first rocker arm 1.

[0055] Next, the external handle or electric lock stops pulling on the cable connector 2c, and the return spring 12 returns the second rocker arm 2 to its original position through the restoring force. Figure 1 The position shown. Since the second rocker arm 2 no longer pushes the first rocker arm 1, the first rocker arm 1 also returns to its original position due to the restoring force of the torsion spring 13. Figure 1 The location shown.

[0056] (Action of the emergency release device)

[0057] Reference Figure 1 , 5 The operation of the emergency release device is explained.

[0058] In emergency situations such as vehicle collisions or power outages, there is a possibility that signals may not be sent to the motor of the first electric arm 8, so it is necessary to be able to unlock manually from inside the vehicle.

[0059] When the second control lever 5 is in Figure 1 In the indicated state, when the occupant operates the emergency release device, the device pulls the cable mounting part 3b of the third rocker arm 3 via a cable (not shown), causing the third rocker arm 3 to rotate clockwise. Figure 5 As shown, the third rocker arm 3 pushes the second idler pin 7 through the lower surface of the protrusion 3a, thereby pushing the first rocker arm 1 to rotate around the axis 11 via the second idler pin 7. Thus, the first rocker arm 1 can unlock the sliding door by operating the front lock and electric rear lock via a pull cable, thereby opening the sliding door. At this time, the torsion spring 13 is tightened by the first rocker arm 1.

[0060] Next, the occupants stopped operating the emergency release device, and the first rocker arm 1 returned to its original position due to the restoring force of the torsion spring 13. Figure 1 The position shown is such that the first rocker arm 1, through the second idle pin 7, drives the third rocker arm 3 to return to the position. Figure 1 The location shown.

[0061] In this way, even if the first electric arm 8 is not working, the third rocker arm 3 can still rotate the first rocker arm 1 independently of the second rocker arm 2, thereby controlling the front lock and electric rear lock of the sliding door and realizing the emergency unlocking function.

[0062] (Actions of child health institutions)

[0063] Reference Figure 1 , 6 7. A description of the child care institution for this implementation method.

[0064] exist Figure 1 In the unlocked state shown, when the vehicle's ECU receives a command from the occupant to activate the child safety control system, it sends a control signal to the motor of the second electric arm 9, thereby controlling the second electric arm 9 to... Figure 1 The state shown is reversed counterclockwise. This causes the second electric arm 9 to rotate the second control lever 5 clockwise, thereby causing the second control lever 5 to move the second idler pin 7 upwards in the second elongated hole 1b via the second sliding groove 5a. Thus, the second idler pin 7 moves from... Figure 1 The second unlock position in the middle is moved to Figure 6 The second locking position is such that the second idler pin 7 does not abut against the lower surface of the protrusion 3a. Therefore, even if the occupant operates the emergency brake and pulls the third rocker arm 3 via the cable, the third rocker arm 3 cannot drive the first rocker arm 1 to rotate via the second idler pin 7, and thus cannot unlock the sliding door by controlling the front lock and electric rear lock of the sliding door through the first rocker arm 1. This prevents the sliding door from being unlocked by the occupant accidentally operating the emergency brake while the vehicle is in motion.

[0065] In addition, Figure 6 In the indicated state, when the vehicle's ECU receives a command from the occupant to release the child safety insurance, it sends a control signal to the motor of the second electric arm 9, thereby controlling the second electric arm 9 to... Figure 6 The state shown indicates clockwise rotation. Consequently, the second electric arm 9 drives the second control lever 5 to rotate counterclockwise, thus causing the second control lever 5 to move the second idle pin 7 from the second sliding groove 5a. Figure 6 The second locking position in the middle is moved to Figure 1 The second unlocking position is reached, causing the second idle pin 7 to abut against the lower surface of the protrusion 3a. Thus, the occupant can control the front lock and electric rear lock of the sliding door by operating the emergency release device as described above.

[0066] In addition, such as Figure 7 As shown, since the rotation of the second rocker arm 2 and the rotation of the third rocker arm 3 are independent of each other, even when Figure 6Even when the child safety mechanism is activated, the second rocker arm 2 can rotate the first rocker arm 1 by operating the external handle or the unlock button. At this time, because the upper surface of the protrusion 3a of the third rocker arm 3 is formed into a smooth arc bulging radially outward, when the emergency release device is released and the third rocker arm 3 is reset by a torsion spring (not shown), the second idler pin 7 can disengage from the upper surface of the protrusion 3a as the first rocker arm 1 rotates and slide freely in the second sliding groove 5a and the second elongated hole 1b. Therefore, the third rocker arm 3, the second control lever 5, and the second electric arm 9 do not affect the rotation of the first rocker arm 1. That is, activating the child safety mechanism does not affect the operation based on the external handle or the unlock button.

[0067] (Effects of the implementation method)

[0068] The effects of this embodiment will be explained below.

[0069] In this embodiment, by connecting both the first control lever 4 and the second control lever 5 to the first rocker arm 1, and connecting both the outer handle cable and the release cable to the second rocker arm 2, the number of rocker arms is reduced. This simplifies the device structure and reduces manufacturing costs while ensuring the functionality of the door control device.

[0070] In this embodiment, by setting the emergency release device as a handle protruding from the interior side of the vehicle door, it can be used as an inner handle even when there is no emergency. Therefore, the inner handle can be eliminated, and thus the rocker arm connected to the inner handle can be eliminated, thereby further reducing manufacturing costs.

[0071] Furthermore, because a child safety mechanism driven by a second electric arm 9 is provided, the emergency release device can be locked through simple operation or automatically by the vehicle's ECU. Therefore, compared to situations where the emergency release device is covered with a cover or other means to prevent accidental operation, it is not necessary to hide the emergency release device, thus facilitating its use by occupants.

[0072] Furthermore, in the event of a vehicle collision, a signal can be sent to the motor of the second electric arm 9 via a backup power source, causing the second electric arm 9 to automatically move the second idle pin 7 to the second unlocked position. This ensures safety during a vehicle collision.

[0073] Furthermore, since the rotations of the second rocker arm 2 and the third rocker arm 3 are independent of each other, and the first control lever 4 and the second control lever 5 are controlled by the first electric arm 8 and the second electric arm 9 respectively, different locking / unlocking logics can be implemented by designing the timing of the control signals sent from inside the vehicle to the first electric arm 8 and the second electric arm 9, thus meeting the needs of different vehicle manufacturers. For example, it can be designed so that when the occupant sends a locking command, the first electric arm 8 and the second electric arm 9 are simultaneously driven to move both the first idler pin 6 and the second idler pin 7 to the locked position; alternatively, it can be designed so that the occupant drives the first electric arm 8 and the second electric arm 9 separately through different commands.

[0074] In addition, since the emergency release device is connected to the third rocker arm 3 via a pull cable, compared to the case where the emergency release device is directly installed on the door control device, the emergency release device can be placed in a location that is easy for the occupants to find, thus increasing the design flexibility.

[0075] Furthermore, since this embodiment eliminates the interior handle and allows for the arbitrary installation of emergency release devices, the entire door control device can be housed within the door trim without protruding into the vehicle interior. This results in a more consistent door trim design, enhancing both the aesthetics and design flexibility of the interior.

[0076] (Other implementation methods)

[0077] The preferred embodiments of the present invention have been described above, but the present invention is not limited thereto. Various modifications are possible without departing from the spirit of the present invention.

[0078] In the above embodiment, the child protection mechanism consisting of the second control lever 5 and the second electric arm 9 has been described, but it is not limited to this. For example, instead of using the second electric arm 9, a control handle manually operated by an occupant inside the vehicle can be used instead. This control handle protrudes from the interior side of the vehicle door and is rotatably connected to the other end of the second control lever 5 via a cable or linkage, so that when the control handle is manually operated, it can drive the second control lever 5 to rotate. The function of the child protection mechanism described above can also be achieved with such a control handle.

[0079] In the above embodiment, the emergency release device is described as a handle-shaped part exposed on the interior side of the vehicle door, but it is not limited thereto. The specific shape of the emergency release device is not particularly limited, as long as it is a shape that is convenient for the user to operate.

[0080] Furthermore, the ECU can be instructed to send signals to the motor of the first electric arm 8 or the motor of the second electric arm 9 as described in the above embodiments through various known methods, such as physical locking and unlocking buttons, in-vehicle touchscreens, applications on the occupant's mobile terminal, and car keys. Of course, the ECU can also automatically send the aforementioned signals based on the current state of the vehicle. Alternatively, the occupant can also send signals directly to the motors of the first electric arm 8 and the second electric arm 9 without going through the vehicle's ECU.

[0081] The present invention has been described above with reference to specific examples. However, the present invention is not limited to these specific examples. Designs obtained by those skilled in the art through appropriate design modifications to these specific examples, as long as they possess the features of the present invention, are also included within the scope of the present invention.
