Description

Technical Field

[0001] This utility model relates to a vehicle door control device. Background Technology

[0002] In recent years, with the widespread adoption of electronic control technology in vehicles, the opening and closing of car doors has increasingly adopted electronic control methods. Most existing electronically controlled doors have eliminated the internal door handle, replacing it with an emergency unlocking mechanism (hereinafter referred to as the emergency unlocking device) for manual unlocking via a cable in emergencies. However, as safety requirements in emergency situations have become more standardized, there is a requirement that the emergency unlocking mechanism be placed in a location easily visible to occupants. If the emergency unlocking mechanism is placed in an easily visible location, occupants may mistake it for the internal handle used under normal circumstances. To prevent accidental operation of the emergency unlocking mechanism, it needs to be locked under normal, malfunction-free conditions.

[0003] In view of the above, in order to enhance the passenger experience and eliminate the sense of inconvenience caused by the fact that the emergency unlocking mechanism cannot be used as an inner handle, there is a need for a structure that can enable the emergency unlocking mechanism to also function as an inner handle. Utility Model Content

[0004] The purpose of this invention is to provide a door control device that enables the emergency unlocking device to also function as an inner handle.

[0005] One embodiment of the vehicle door control device of this utility model includes: a linkage mechanism, which includes a first rocker arm, a control arm, a first control lever, and a first drive arm. The first drive arm is driven by a first motor and is rotatably connected to one end of the first control lever. The first drive arm moves via the first control lever between a first movable part in a first guide portion of the first rocker arm and a first unlocked position that can abut against the control arm and a first locked position that cannot abut against the control arm. The control arm is connected to the vehicle's outer door handle. The control arm is provided with a first pull cable that can drive the control arm to rotate, and the first drive arm is provided with a second pull cable that can drive the first drive arm to rotate. Both the first pull cable and the second pull cable are connected to an emergency unlocking device.

[0006] According to the above structure, by also providing a second pull cable connected to the emergency unlocking device on the first drive arm, the first drive arm can be manually controlled via the emergency unlocking device, thereby setting the first movable part to the first unlocked position via the first control lever. That is, the lock on the control arm can be unlocked by manually operating the emergency unlocking device, making it easy to use the emergency unlocking device as a normal inner handle.

[0007] In addition, in the above method, it is preferred that the control arm includes a second rocker arm and a third rocker arm that rotate coaxially, the first movable part abuts against the second rocker arm, the third rocker arm abuts against the first rocker arm to drive the first rocker arm to rotate, the first pull cable is disposed on the third rocker arm, and the outer handle is connected to the second rocker arm.

[0008] According to the above structure, by dividing the control arm into a second rocker arm and a third rocker arm, the third rocker arm used for connecting to the emergency unlocking device can be separated from the second rocker arm, so that the third rocker arm does not affect the function of the second rocker arm used for connecting to the external handle.

[0009] In addition, in the above-described manner, it is preferred that the linkage mechanism further includes a second control lever, which, when rotated, drives the second movable part to move between a second unlocked position in the second guide part of the first rocker arm that can abut against the third rocker arm and a second locked position that cannot abut against the third rocker arm.

[0010] Based on the above structure, the third rocker arm connected to the emergency unlocking device can be locked / unlocked by operating the second control lever. This further improves the operability of the door control device.

[0011] In addition, in the above-described manner, it is preferred that the linkage mechanism further includes a second drive arm, which is driven by a second motor and rotatably connected to one end of the second control lever. The second drive arm moves the second movable part between the second unlock position and the second locked position via the second control lever.

[0012] According to the above structure, the second movable part can be electrically controlled by the second motor to lock / unlock the third rocker arm connected to the emergency unlocking device. This improves the ease of use of the door control device.

[0013] Furthermore, in the above-described manner, it is preferable that the door control device can be set to a locking mode and a locking mode. When the door control device is set to the locking mode, the first movable part is located in the first locked position, and the second movable part is located in the second locked position. When the door control device is not set to the locking mode, when the first drive arm is pulled by the second cable, the vehicle's electronic control device sends a signal to the second motor to instruct the second drive arm to rotate, thereby the second motor drives the second movable part to move to the second unlocked position. When the door control device is set to the locking mode, the second motor does not operate.

[0014] According to the above structure, by actuating the second motor in response to the pulling of the first motor, the door control device can be fully unlocked by pulling the first motor using the emergency unlocking device. Therefore, occupants can unlock the sliding door by pulling the emergency unlocking device twice. This allows the emergency unlocking device to be used as a regular interior handle.

[0015] Furthermore, by setting a locking mode, it is possible to prevent the door from being opened via the emergency unlocking device while the vehicle is in motion. That is, the second motor is used both as the motor for locking / unlocking the interior handle and as the motor for the locking mode. This improves the security of the door control system and further enhances the function of the emergency unlocking device as a normal interior handle.

[0016] Furthermore, in the above-described manner, it is preferable that the second motor is configured to operate even when the door control device is set to the locked mode, provided that certain conditions are met.

[0017] The aforementioned conditions, such as emergency situations like collisions or fires, can be determined by the manufacturer of vehicles equipped with door control devices. According to this structure, by automatically releasing the locking mechanism in emergency mode, the emergency unlocking device can be used as an inner handle under normal circumstances, and can also be used for escape in emergencies.

[0018] In addition, in the above method, it is preferable that the second control lever is provided with a paddle, and the second control lever is rotated by operating the paddle.

[0019] Based on the above structure, the third rocker arm can be manually locked / unlocked via a paddle.

[0020] In addition, in the above method, it is preferable to also include a position detection device, which is located at a position that can be contacted when the second control lever is rotated. The position detection device is configured to send a signal to notify that the second movable part is in the second unlocked position when it is contacted by the second control lever.

[0021] Based on the above structure, even when the second control lever is manually operated, the position of the second movable part controlled by the second control lever can be determined by the position detection device. Therefore, the controllability of the door control device can be improved.

[0022] In addition, in the above method, it is preferable to also include a sensing control device, which is located at a position that can be contacted when the third rocker arm rotates. The sensing control device is configured to send a signal to the vehicle's electric opening and closing mechanism to instruct the door to open or close when the first movable part is in the first unlocked position and the second movable part is in the second unlocked position.

[0023] Based on the above structure, by setting a sensor control device and configuring it to send a signal to the electric opening and closing mechanism only when the first movable part is in the first unlocked position and the second movable part is in the second unlocked position, it is also possible to electrically open the door by pulling the emergency unlocking device twice while the door is closed. This further improves the function of the emergency unlocking device as a regular inner handle.

[0024] In addition, in the above method, it is preferred that the linkage mechanism further includes a fourth rocker arm, which can abut against the third rocker arm and rotate together with the third rocker arm. The fourth rocker arm is provided with a third pull line, which is used to operate the full-open limit lock of the car door.

[0025] Based on the above structure, when the sliding door is fully open, the fully open limit lock can be operated regardless of the position of the first or second movable part, thereby using the emergency unlocking device as a handle for closing the door. This further improves the function of the emergency unlocking device as a regular inner handle.

[0026] In addition, in the above-described manner, it is preferable that the emergency unlocking device is in the form of a handle protruding from the interior side of the vehicle door.

[0027] Based on the above structure, the design of the emergency unlocking device can be further improved. This allows the emergency unlocking device to be visually recognized as a regular internal handle.

[0028] In addition, in the above method, it is preferred that a base plate and a return spring are also included. The third rocker arm and the fourth rocker arm are rotatably mounted on the base plate via a shaft. One end of the return spring is connected to the fourth rocker arm and the other end is connected to the base plate. When the emergency unlocking device finishes operating the third rocker arm, the return spring returns the fourth rocker arm and the third rocker arm to their original positions.

[0029] Based on the above structure, the fourth rocker arm and the third rocker arm can be reset together by a return spring, thereby simplifying the structure of the door control device and saving costs.

[0030] In addition, in the above-described manner, it is preferred that the fourth rocker arm abuts against the second contact portion of the third rocker arm via the first contact portion, and the fourth rocker arm also abuts against the fourth contact portion of the second rocker arm via the third contact portion. The second rocker arm, the third rocker arm, and the fourth rocker arm are rotatably mounted on the base plate of the door control device via a shaft, and the second contact portion, the first contact portion, the fourth contact portion, and the third contact portion are arranged sequentially in the rotation direction of the fourth rocker arm.

[0031] According to the above structure, when the second rocker arm pushes the fourth rocker arm to rotate, the third rocker arm does not rotate with the fourth rocker arm. Similarly, when the third rocker arm pushes the fourth rocker arm to rotate, the second rocker arm does not rotate with the fourth rocker arm. Therefore, with a simple structure, the fourth rocker arm can be operated independently according to the operation of the second or third rocker arm, effectively preventing the function of the door control device from becoming disordered.

Detailed Implementation

[0045] 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.

[0046] <First Implementation Method>

[0047] (Structure of the control device)

[0048] First, refer to Figure 1 , 2 The specific structure of the door control device 100 will be described. Figure 1 This diagram shows that the door control device 100 is in the unlocked state.

[0049] like Figure 1 , Figure 2 As shown, the door control device 100 includes a base plate BS, a linkage mechanism, a first motor M1, and a second motor M2. The linkage mechanism includes: a first rocker arm 1, a second rocker arm 2, a third rocker arm 3, a fourth rocker arm 8, a first control lever 4, a second control lever 5, a first drive arm DA1, and a second drive arm DA2. The first rocker arm 1, the second rocker arm 2, the third rocker arm 3, and the fourth rocker arm 8 are rotatably mounted on the base plate BS via a shaft 9.

[0050] The first rocker arm 1 is elongated and has a first guide portion 1a and a second guide portion 1b. The first guide portion 1a is located at one end of the first rocker arm 1 along its length and extends along the length of the first rocker arm 1. The second guide portion 1b extends from a portion near the middle of the first rocker arm 1 along its length in a direction intersecting the length direction (obliquely upward in this embodiment). Two pull-wire mounting portions 1c are provided at the other end of the first rocker arm 1 along its length for operating, for example, the front lock and rear lock of a sliding door (not shown) via pull wires.

[0051] The first control lever 4 is mounted on the substrate BS. A third guide portion 4a is provided at one end of the first control lever 4. A first movable portion 6 passes sequentially through the first guide portion 1a and the third guide portion 4a of the first rocker arm 1, thereby rotatably connecting the first guide portion 1a to the first control lever 4 via the first movable portion 6. In this embodiment, the first movable portion 6 is a pin-shaped component. The first drive arm DA1 is driven by the first motor M1 and is rotatably connected to the other end of the first control lever 4, thereby enabling the first drive arm DA1 to drive the first control lever 4 to rotate.

[0052] The second control lever 5 is mounted on the substrate BS. A fourth guide portion 5a is provided at one end of the second control lever 5. A second movable portion 7 passes sequentially through the second guide portion 1b of the first rocker arm 1 and the fourth guide portion 5a, thereby rotatably connecting the second guide portion 1b to the second control lever 5 via the second movable portion 7. In this embodiment, the second movable portion 7 is a pin-shaped component. The second drive arm DA2 is driven by the second motor M2 and rotatably connected to the other end of the second control lever 5, thereby enabling the second drive arm DA2 to drive the second control lever 5 to rotate.

[0053] 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.

[0054] The third rocker arm 3 has a cable mounting portion 3b for mounting a pull cable. The third rocker arm 3 is connected to an emergency unlocking device via a first pull cable, which can pull the third rocker arm 3 to rotate. In this embodiment, the emergency unlocking device is in the form of a handle protruding from the interior side of the vehicle door. Figure 1 In this context, I / H represents the emergency unlocking device, and... Figure 1 For simplicity, the diagram only schematically illustrates the connection between the first pull wire and the emergency unlocking device, and does not represent the actual structure. Detailed instructions regarding the operation of the emergency unlocking device will be provided later.

[0055] The combination of the second rocker arm 2 and the third rocker arm 3 is equivalent to the "control arm" in this utility model.

[0056] Furthermore, the first drive arm DA1 has a cable mounting portion DA1a for mounting a cable, and the first drive arm DA1 is connected to the aforementioned emergency unlocking device via a second cable. Similarly, in Figure 1 For simplicity, the diagram only schematically illustrates the connection between the second pull wire and the emergency unlocking device, and does not represent the actual structure.

[0057] The second rocker arm 2 is provided with an abutment portion 2a. The first drive arm DA1, via the first control lever 4, positions the first movable part 6 in the first guide portion 1a of the first rocker arm 1 so that it can abut against the abutment portion 2a. Figure 1 The positions shown (hereinafter referred to as the first unlocking position) and the positions that cannot abut against the contact part 2a ( Figure 3 The first rocker arm 1 can move between the positions shown (hereinafter referred to as the first locked position). When the first movable part 6 is in the first unlocked position, the first rocker arm 1 can rotate with the rotation of the second rocker arm 2. When the first movable part 6 is in the first locked position, the first rocker arm 1 cannot rotate with the rotation of the second rocker arm 2.

[0058] The third rocker arm 3 is provided with a first protrusion 3a and a second protrusion 3c. The second drive arm DA2, via the second control lever 5, allows the second movable part 7 in the second guide part 1b of the first rocker arm 1 to abut against the third rocker arm 3. Figure 1 The position shown (hereinafter referred to as the second unlock position) and the position where it cannot abut against the third rocker arm 3 ( Figure 4 The first rocker arm 1 can move between the positions shown (hereinafter referred to as the second locked position). When the second movable part 7 is in the second unlocked position, the first rocker arm 1 can rotate with the rotation of the third rocker arm 3. When the second movable part 7 is in the second locked position, the first rocker arm 1 cannot rotate with the rotation of the third rocker arm 3.

[0059] The door control device 100 also includes a sensing control device SW, which is disposed on the base plate BS and located at a position that the second protrusion 3c can contact when the third rocker arm 3 rotates.

[0060] The fourth rocker arm 8 has a first contact portion 8a and a third contact portion 8b. The first contact portion 8a abuts against the second contact portion 3d of the third rocker arm 3, thereby allowing the fourth rocker arm 8 to rotate together with the third rocker arm 3. The third contact portion 8b abuts against the fourth contact portion 2d of the second rocker arm 2, thereby allowing the fourth rocker arm 8 to also rotate together with the second rocker arm 2. The fourth rocker arm 8 also has a pull cable mounting portion 8c for operating, for example, a fully open limit lock of a sliding door (not shown) via a pull cable.

[0061] The door control device 100 is also provided with return springs SP1 and SP2. One end of the return spring SP1 is connected to the fourth rocker arm 8, and the other end is connected to the base plate BS. When the return spring SP1 causes the fourth rocker arm 8 to rotate counterclockwise, the fourth rocker arm 8 pushes the third rocker arm 3 to rotate counterclockwise together via the first contact part 8a and the second contact part 3d.

[0062] One end of the return spring SP2 is connected to the second rocker arm 2, and the other end is connected to the substrate BS. Furthermore, the first rocker arm 1 is provided with a fifth contact portion 1d. When the return spring SP2 causes the second rocker arm 2 to rotate counterclockwise, the second rocker arm 2 pushes the first rocker arm 1 to rotate counterclockwise together via the fifth contact portion 1d.

[0063] In addition, such as Figure 1 As shown, the second contact portion 3d, the first contact portion 8a, the fourth contact portion 2d, and the third contact portion 8b are arranged sequentially in the rotation direction (clockwise) of the fourth rocker arm 8. Therefore, when the second rocker arm 2 pushes the fourth rocker arm 8 to rotate, the third rocker arm 3 does not rotate with the fourth rocker arm 8. Similarly, when the third rocker arm 3 pushes the fourth rocker arm 8 to rotate, the second rocker arm 2 does not rotate with the fourth rocker arm 8.

[0064] In addition, such as Figure 2 As shown, the first control lever 4 in this embodiment is a structure in which one side and the other side (hereinafter referred to as one side and the other side) in the long side direction are connected via a rotating connection 4b. This rotating connection 4b is configured such that, when the movement of one side or the other side is not restricted, it maintains the relative positional relationship between the two sides, allowing one side to drive the other side to rotate via the rotating connection 4b; when the movement of one side or the other side is restricted, it changes the relative positional relationship between the two sides, allowing the unrestricted side to rotate around the rotating connection 4b. Furthermore, when the restriction on the restricted side is released, the rotating connection 4b returns the position of the one side and the other side to their original state. This structure can be implemented, for example, by providing a torsion spring in the rotating connection 4b.

[0065] This structure makes the first control lever 4 a so-called panic lever. For example, assuming that in an emergency, an external rescuer keeps pulling the outside handle, causing the second rocker arm 2 to jam the first control lever 4 at the third guide part 4a via the second movable part 6, the side of the first control lever 4 without the third guide part 4a can still be rotated by the first drive arm DA1.

[0066] In addition, the second control lever 5, like the first control lever 4, is also provided with a rotating connection part 5b, which constitutes a so-called forced unlocking lever.

[0067] Additionally, the door control device 100 is connected to the vehicle's electronic control unit, for example, and can receive commands from the occupants via the electronic control unit. The electronic control unit is, for example, an electronic control unit (ECU) or a CPU.

[0068] (Lock function)

[0069] The following is for reference Figure 1 , 3 Sections 1-5 describe the locking function of the door control device 100.

[0070] When the vehicle is in motion, or when the vehicle is stopped and no key is detected, or when the occupants inside the vehicle have set the locking mode, it is necessary to ensure that the front and rear locks of the sliding doors are locked.

[0071] In this case, for example, a control signal is sent to the first motor M1 via the vehicle's electronic control device, thereby controlling the first drive arm DA1 from... Figure 1 The state shown is a counter-clockwise rotation. Consequently, the first drive arm DA1 drives the first control lever 4 to rotate clockwise, thereby causing the first control lever 4 to move the first movable part 6 upward within the first guide part 1a via the third guide part 4a. Thus, the first movable part 6 moves from... Figure 1 The first unlock position in the game is moved to Figure 3 The first movable part 6 is locked in the first locking position, so that the first movable part 6 does not abut against the 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 rear lock of the sliding door to unlock via the first rocker arm 1.

[0072] In addition, control signals are sent to the second motor M2 via the vehicle's electronic control devices, thereby controlling the second drive arm DA2 from... Figure 1 The state shown is rotated counterclockwise. Consequently, the second drive arm DA2 drives the second control lever 5 to rotate clockwise, thereby causing the second control lever 5 to move the second movable part 7 upward within the second guide part 1b via the fourth guide part 5a. Thus, the second movable part 7 moves from... Figure 1 The second unlock position in the middle is moved to Figure 4 The second locking position is such that the second movable part 7 does not abut against the lower surface of the first protrusion 3a.

[0073] Therefore, the door control device 100 becomes Figure 5 The lock mode shown.

[0074] In this state, even if the occupant operates the emergency unlocking device and pulls the third rocker arm 3 via the first cable, the third rocker arm 3 cannot drive the first rocker arm 1 to rotate via the second movable part 7, and therefore cannot control the front and rear locks of the sliding door to unlock via the first rocker arm 1. This prevents the sliding door from being unlocked by the occupant accidentally operating the emergency unlocking device while the vehicle is in motion.

[0075] (First opening and closing method)

[0076] The following is for reference Figure 1 , 3 6. The first opening and closing method of the door control device 100 is described.

[0077] In situations where the sliding door needs to be opened or closed while the vehicle is stationary, the vehicle's electronic control unit automatically sends a control signal to the first motor M1, or responds to the occupant's operation of the door opening / closing button, thereby controlling the first drive arm DA1 to move from... Figure 3 The indicated position is rotated clockwise. Consequently, the first drive arm DA1 drives the first control lever 4 to rotate counterclockwise, thereby causing the first control lever 4 to move the first movable part 6 downward within the first guide part 1a via the third guide part 4a. Thus, the first movable part 6 moves from... Figure 3 The first locked position in the middle is moved to Figure 1 The first unlocked position is reached, so that the first movable part 6 abuts against the abutting part 2a of the second rocker arm 2.

[0078] Next, as Figure 6 As shown, the external handle or electric lock (e.g., when the driver issues an open door command via the central control) pulls the cable connector 2c via the external handle cable or release cable, causing the second rocker arm 2 to rotate clockwise via the cable connector 2c. In this way, the second rocker arm 2 pushes the first movable part 6 in the first guide part 1a of the first rocker arm 1 via the abutment part 2a, thereby pushing the first rocker arm 1 to rotate clockwise around the axis 9 via the first movable part 6. Thus, the first rocker arm 1 operates the front and rear locks of the sliding door via the cable.

[0079] Furthermore, when the second rocker arm 2 rotates, it pushes the third contact part 8b of the fourth rocker arm 8 via the fourth contact part 2d, causing the fourth rocker arm 8 and the second rocker arm 2 to rotate clockwise together. Thus, the fourth rocker arm 8 operates the fully open limit lock of the sliding door via a pull cable.

[0080] In this way, as the first rocker arm 1 and the fourth rocker arm 8 rotate, the sliding door can be electrically opened and closed.

[0081] exist Figure 6 In the state shown, the return spring SP2 is stretched as the second rocker arm 2 rotates, and the return spring SP1 is stretched as the fourth rocker arm 8 rotates.

[0082] Next, the external handle or electric lock stops pulling on the cable connector 2c, and the return spring SP2 returns the second rocker arm 2 to its original position through the restoring force. Figure 1 The position shown. Since the pressure of the fourth contact 2d on the third contact 8b disappears, the return spring SP1 restores the fourth rocker arm 8 to its original position via the restoring force. Figure 1 The location shown.

[0083] (Second opening and closing method)

[0084] The following is for reference Figure 1 , 4 Sections 5 and 7 describe the second opening and closing method of the door control device 100, namely the double-pull function.

[0085] The door control device 100 is set to Figure 4 In the locked mode shown, where the first movable part 6 is in the first locked position and the second movable part 7 is in the second locked position, the occupant can open the door by pulling the emergency unlocking device twice.

[0086] Specifically, when the occupant pulls the emergency unlocking device for the first time, the first drive arm DA1 is pulled via the second cable, thereby causing the first control lever 4 to move from the first drive arm DA1 to the first control lever 4. Figure 5 The state shown is rotated to Figure 4 The state shown.

[0087] Simultaneously, since the first motor M1 is also driven to rotate by the first drive arm DA1 (e.g., the rotor rotates), the electronic control device, for example, detects a change in the rotational position of the first motor M1. In response, the electronic control device sends a control signal to the second motor M2, causing the second motor M2 to rotate. Thus, the second motor M2 drives the second drive arm DA2 to rotate, and via the second control lever 5, moves the second movable part 7 to the second unlocked position, becoming... Figure 1 The state shown.

[0088] Thus, when the occupants pull the emergency unlocking device again, such as Figure 7 As shown, the emergency unlocking device pulls the cable mounting part 3b of the third rocker arm 3 via the first cable, causing the third rocker arm 3 to rotate clockwise. The third rocker arm 3 pushes the second movable part 7 via the lower surface of the first protrusion 3a, thereby pushing the first rocker arm 1 to rotate around the axis 9 via the second movable part 7. Thus, the first rocker arm 1 unlocks the sliding door by operating the front and rear locks via the cable.

[0089] Simultaneously, as the third rocker arm 3 rotates, the second protrusion 3c contacts the sensing control device SW. In response, the sensing control device SW sends a signal to the vehicle's electric opening and closing mechanism instructing the door to be opened. Thus, the occupant can electrically open the door by pulling the emergency unlocking device twice.

[0090] Furthermore, with the sliding door fully open, the occupant can operate the emergency unlocking device, which, via the first cable, causes the third rocker arm 3 to rotate, thereby unlocking the fully open limit lock connected to the fourth rocker arm 8. At this time, the second protrusion 3c also contacts the sensing control device SW, which then sends a signal to the vehicle's electric opening and closing mechanism instructing the door to close. Thus, by pulling the emergency unlocking device while the door is fully open, the occupant can electrically close the door.

[0091] (Childcare Model)

[0092] Next, the child care model of this embodiment will be explained.

[0093] As described above, the emergency unlocking device of this embodiment can open the car door by pulling twice. Therefore, there is a concern that children, for example, might operate the emergency unlocking device and open the car door while the vehicle is in motion. To address this, this embodiment also includes a child safety mode.

[0094] Specifically, in this embodiment, for example, an occupant can issue a command to the vehicle's electronic control devices to set them to child safety mode, i.e., lockout mode, via a child safety button located on the central control panel or around the door. This allows the door control device 100 to be set to lockout mode.

[0095] When the device is set to the locked mode, even if the occupant operates the emergency unlocking device to pull the first drive arm DA1 to rotate, the electronic control device will not issue an action command to the second motor M2. That is, in this locked mode, the second motor M2 does not operate.

[0096] Therefore, since the second movable part 7 is always in the second locked position, even if the occupant operates the emergency unlocking device and pulls the third rocker arm 3 via the first cable, the third rocker arm 3 cannot drive the first rocker arm 1 to rotate via the second movable part 7. Furthermore, the sensor control device SW is configured to send a signal to the electric opening and closing mechanism only when the first movable part 6 is in the first unlocked position and the second movable part 7 is in the second unlocked position. Therefore, in the locked mode, the sensor control device SW will not send the aforementioned signal.

[0097] In this way, by setting it to the locked mode, it is possible to prevent the car door from being opened by accidental operation of the emergency unlocking device.

[0098] (Actions in an emergency)

[0099] Reference Figure 1 , 5 7. The operation of the emergency unlocking device in this embodiment will be explained.

[0100] In the event of a vehicle collision, passengers can open the sliding door by operating the emergency unlocking device. In this embodiment, the emergency unlocking device can handle both situations where the vehicle has power and situations where the vehicle loses power due to a collision. The operation in these two situations will be explained below.

[0101] Furthermore, in the following description, the initial state is described with the first movable part 6 in the first locked position and the second movable part 7 in the second locked position, and the door control device 100 set to the locked mode.

[0102] (1) The vehicle is not powered off

[0103] When the vehicle is not powered off, meaning its electronic controls and electric actuators are still functioning properly, the electronic controls automatically switch to emergency mode in case of an emergency, such as a collision or fire.

[0104] In emergency mode, when an occupant operates the emergency unlocking device, the device pulls the first drive arm DA1 to rotate via the second cable, thereby moving the first movable part 6 to the first unlock position via the first control lever 4. That is, the door control device 100... Figure 5 become Figure 4 The state shown is as follows. At this time, the electronic control device detects a change in the rotational position of the first motor M1. Because it is in emergency mode, the electronic control device automatically releases the locking mode of the door control device 100 and sends a control signal to the second motor M2, causing the second motor M2 to rotate. As a result, the second motor M2 drives the second drive arm DA2 to rotate, which in turn moves the second movable part 7 to the second unlocked position via the second control lever 5. Thus, the door control device 100 becomes... Figure 1 The state shown.

[0105] Then, when the occupants operate the emergency unlocking device again, such as Figure 7 As shown, the emergency unlocking device pulls the cable mounting part 3b of the third rocker arm 3 via the first cable, causing the third rocker arm 3 to rotate clockwise. The third rocker arm 3 pushes the second movable part 7 via the lower surface of the first protrusion 3a, thereby pushing the first rocker arm 1 to rotate around the axis 9 via the second movable part 7. Thus, the first rocker arm 1 unlocks the sliding door by operating the front and rear locks via the cable.

[0106] At the same time, as the third rocker arm 3 rotates, the second protrusion 3c contacts the sensing control device SW, thereby the sensing control device SW sends a signal to the vehicle's electric opening and closing mechanism to instruct the door to be opened.

[0107] In this way, in an emergency, the occupants can unlock and open the sliding door by operating the emergency unlocking device twice.

[0108] (2) Vehicle power failure

[0109] In the event of a power outage due to a collision or other reasons, the vehicle's electronic control devices and electric actuators will malfunction. When an occupant operates the emergency unlocking device, the first drive arm DA1 is pulled by the second cable and rotates clockwise as shown in the figures. Consequently, the first drive arm DA1, via the first control lever 4, moves the first movable part 6 to the first unlocking position, thus enabling the door control device 100 to... Figure 4 The state shown.

[0110] Simultaneously, since both the electronic control device and the second motor M2 are de-energized, the locking mode cannot be disengaged, nor can the second motor M2 be rotated, thus the second movable part 7 remains in the second locked position. Even if the occupant operates the emergency unlocking device again and pulls the third rocker arm 3 via the first cable, the first rocker arm 1 cannot be rotated. However, since the first movable part 6 is in the first unlocked position, when a rescuer outside the vehicle operates the outer handle, the outer handle pulls the second rocker arm 2, which in turn pushes the first rocker arm 1 to rotate via the first movable part 6. Thus, the first rocker arm 1 can unlock the sliding door and manually open it by operating the front and rear locks of the sliding door via the cable.

[0111] In this way, by having the occupants operate the emergency unlocking device once, rescue personnel outside the vehicle can open the sliding door via the external handle.

[0112] (Effects of this implementation method)

[0113] The effects of this embodiment will be explained below.

[0114] In this embodiment, by also providing a second cable connected to the emergency unlocking device on the first drive arm DA1, the first drive arm DA1 can be manually controlled via the emergency unlocking device, thereby setting the first movable part 6 to the first unlock position via the first control lever 4. That is, the lock on a part of the door control device 100 (the first rocker arm 1 and the second rocker arm 2) can be unlocked by manually operating the emergency unlocking device, making it easy to use the emergency unlocking device as a normal inner handle.

[0115] Furthermore, by activating the second motor M2 in response to the pulling of the first motor M1, the door control device 100 can be fully unlocked by pulling the first motor M1 using the emergency unlocking device. Therefore, occupants can unlock the sliding door by pulling the emergency unlocking device twice. This allows the emergency unlocking device to be used as a regular interior handle.

[0116] Furthermore, in this embodiment, by setting a locking mode, it is possible to prevent the door from being opened via the emergency unlocking device, for example, while the vehicle is in motion. That is, the second motor M2 is used both as a motor for locking / unlocking the inner handle and as a motor for the locking mode. As a result, the security of the door control device 100 can be improved, and the function of the emergency unlocking device as a normal inner handle can be further enhanced.

[0117] Furthermore, by automatically unlocking the lock in emergency mode, the emergency unlocking device can be used as an internal handle under normal circumstances, and can also be used to escape in emergency situations.

[0118] Furthermore, by providing a sensor control device SW, and configuring the sensor control device SW to send a signal to the electric opening and closing mechanism only when the first movable part 6 is in the first unlocked position and the second movable part 7 is in the second unlocked position, it is also possible to electrically open the door by pulling the emergency unlocking device twice while the door is closed. This further improves the function of the emergency unlocking device as a regular inner handle.

[0119] Furthermore, in this embodiment, by also providing a second cable connected to the emergency unlocking device on the first drive arm DA1, even in the event of a vehicle power failure, the first movable part 6 can be mechanically moved to the first unlocked position by pulling the second cable via the emergency unlocking device. This allows external rescue personnel to carry out rescue operations with a single mechanical action, improving the vehicle's safety and reliability.

[0120] In this embodiment, by using the first pull cable and the second pull cable to connect to the emergency unlocking device, the location of the emergency unlocking device is not limited to the periphery of the door control device 100, but can be set at any location that can be seen by the occupants.

[0121] In this embodiment, only one emergency unlocking device is provided, and the rotation directions of the third rocker arm 3, which is pulled by the first cable via the emergency unlocking device, and the first drive arm DA1, which is pulled by the second cable, are the same. That is, the operating direction when using the emergency unlocking device as an inner handle is the same as the operating direction of the emergency unlocking device in an emergency. Therefore, even in an emergency such as a vehicle collision, occupants can easily operate the emergency unlocking device without misoperation due to panic. In this embodiment, the fully open limit lock is connected to the fourth rocker arm 8, which rotates with the rotation of the third rocker arm 3. With this structure, in the fully open state of the sliding door, the fully open limit lock can be operated regardless of the position of the first movable part 6 or the second movable part 7, thereby using the emergency unlocking device as a handle for closing the door. This further improves the function of the emergency unlocking device as a normal inner handle.

[0122] In this embodiment, by providing a rotating connection part 4b and a rotating connection part 5b on the first control lever 4 and the second control lever 5, even if occupants inside the vehicle hold onto the emergency unlocking device due to panic, or rescue personnel outside the vehicle hold onto the outer handle, the operation of the first drive arm DA1 or the second drive arm DA2 on the first control lever 4 and the second control lever 5 will not be affected. Therefore, the usability of the door control device 100 can be further improved.

[0123] <Second Implementation Method>

[0124] refer to Figure 8 , 9 The door control device 100A of the second embodiment will be described. Furthermore, in the second embodiment, structures that are the same as or equivalent to those in the first embodiment are labeled with the same symbols, and repeated descriptions are omitted.

[0125] In this embodiment, the aforementioned components such as the second motor M2, second drive arm DA2, third rocker arm 3, and second control lever 5 are not provided, depending on factors such as the requirements of the vehicle model or the vehicle manufacturer. In this embodiment, it is assumed that the mechanism for locking the emergency unlocking device is directly installed on the door surrounding the emergency unlocking device, and the locking and unlocking operations of the emergency unlocking device are performed manually by the occupant.

[0126] Accordingly, compared to the first embodiment, a first rocker arm 1A is provided instead of the first rocker arm 1 and the fourth rocker arm 8. Furthermore, a second rocker arm 2A is provided instead of the second rocker arm 2 and the third rocker arm 3. Specifically, as... Figure 8 , 9As shown, the first rocker arm 1A is provided with three cable mounting parts 1c, used to operate, for example, the front lock, rear lock, and full-open limit lock of the sliding door (not shown) via cable. The second rocker arm 2A is provided with a cable mounting part 2e for mounting a cable. The second rocker arm 2A is connected to an emergency unlocking device via a first cable, so that the emergency unlocking device can pull the second rocker arm 2A to rotate. Furthermore, the second rocker arm 2A is equivalent to the "control arm" in this invention.

[0127] Furthermore, the first rocker arm 1A and the second rocker arm 2A are rotatably mounted on the substrate BSA via shaft 9A. A torsion spring SP3 is provided on shaft 9A, and when the second rocker arm 2A rotates clockwise, the torsion spring SP3 applies a force to the second rocker arm 2A in the counterclockwise direction. In addition, the second rocker arm 2A pushes the fifth contact portion 1d, causing the first rocker arm 1A to rotate counterclockwise together.

[0128] In this embodiment, the first drive arm DA1 is also connected to the emergency unlocking device via a second cable. Furthermore, similar to the first embodiment, the first control lever 4 is also a so-called forced unlocking lever with a rotating connection portion 4b.

[0129] In this embodiment, when the first movable part 6 is in the first locked position and the emergency unlocking device is unlocked by the user, when the occupant operates the emergency unlocking device, the emergency unlocking device pulls the first drive arm DA1 via the second pull cable, thereby causing the first drive arm DA1 to move the first movable part 6 to the first unlocked position via the first control lever 4. Thus, when the occupant operates the emergency unlocking device again, the second rocker arm 2A rotates the first rocker arm 1A via the second pull cable through the first movable part 6, and the first rocker arm 1A unlocks the sliding door by operating the front and rear locks via the pull cable. Therefore, the occupant can manually open the sliding door.

[0130] In this embodiment, similar to the above embodiment, the occupant can unlock the door control device 100A by pulling the emergency unlocking device twice.

[0131] <Third Implementation Method>

[0132] refer to Figure 10 , 11 The door control device 100B of the third embodiment will be described.

[0133] In this embodiment, the second motor M2 and the second drive arm DA2 are not provided, depending on factors such as the requirements of the vehicle model or the vehicle manufacturer. However, unlike the second embodiment, the second control lever (i.e., the second control lever 5B) is retained, but it is configured to be manually controlled via a paddle 5Bb. Furthermore, the structure of each rocker arm differs from both the first and second embodiments.

[0134] like Figure 10 , 11 As shown, the fifth rocker arm 10, the sixth rocker arm 11, the seventh rocker arm 12, the eighth rocker arm 13, and the ninth rocker arm 14 are rotatably mounted on the substrate BSB via shaft 9B. The fifth rocker arm 10 is provided with a slot 10a and a fifth guide portion 10b, and the sixth rocker arm is provided with a sixth guide portion 11a and two cable mounting portions 11b for operating, for example, the front lock and rear lock of a sliding door (not shown) via a cable. The first movable part 6 passes sequentially through the third guide portion 4a, the sixth guide portion 11a, and the slot 10a of the first control lever 4, thereby driving the fifth rocker arm 10 and the sixth rocker arm 11 to rotate by pushing the first movable part 6. That is, the combination of the fifth rocker arm 10 and the sixth rocker arm 11 corresponds to the first rocker arm 1 in the first embodiment.

[0135] Furthermore, the seventh rocker arm 12 is provided with an abutment portion 12a corresponding to the abutment portion 2a in the first embodiment, and a groove 12b for mounting a cable mounting portion 12c connected to one of the outer handle cable or release cable. The eighth rocker arm 13 is provided with a mounting hole 13a for mounting a cable mounting portion 13b connected to the other of the outer handle cable or release cable. That is, the combination of the seventh rocker arm 12 and the eighth rocker arm 13 is equivalent to the second rocker arm 2 in the first embodiment.

[0136] The ninth rocker arm 14 is provided with a third protrusion 14a corresponding to the first protrusion 3a in the first embodiment, a groove 14b for mounting a pull cable mounting portion 14c connected to the first pull cable for operation of an emergency unlocking device, and a pull cable mounting portion 14d for operating a sliding door (not shown) via a pull cable, such as a fully open limit lock. That is, the ninth rocker arm 14 is equivalent to a combination of the third rocker arm 3 and the fourth rocker arm 8 in the first embodiment.

[0137] In addition, as described above, in this embodiment, a second motor M2 is not provided, but a paddle 5Bb is provided on the second control lever 5B, which can be rotated by operating the paddle 5Bb.

[0138] In this embodiment, the first drive arm DA1 is connected to the second pull cable via the pull cable mounting part DA1a, and is also connected to the emergency unlocking device via the second pull cable. Furthermore, similar to the first embodiment, the first control lever 4 also has a structure called a forced unlocking lever with a rotating connecting part 4b.

[0139] The linkage action between the first control lever 4 and the first movable part 6 is the same as that in the first embodiment. The linkage action between the second control lever 5B and the second movable part 7 is the same as that in the first embodiment, so detailed description is omitted.

[0140] Furthermore, in this embodiment, similar to the first embodiment, a sensor control device SW is provided. When the ninth rocker arm 14 rotates, it can contact the sensor control device SW, thereby achieving the same effect as the first embodiment of automatically opening and closing the sliding door.

[0141] Furthermore, a position detection device SWB is also mounted on the substrate BSB. This position detection device SWB is configured to send a signal indicating that the second movable part 7 is in the second unlocked position when contacted by the second control lever 5B. Specifically, the second movable part 7 is moved to the second unlocked position by rotating the second control lever 5B. Figure 10 When the device is in the second unlocked position, the contact portion 5Bd provided on the second control lever 5B contacts the position detection device SWB, thereby notifying the electronic control device that the locking mode has been released. Thus, similar to the first embodiment described above, it is possible to determine whether the sensing control device SW sends a signal to the electric opening and closing mechanism based on the positions of the first movable portion 6 and the second movable portion 7.

[0142] Furthermore, a return spring SP4 is installed on the ninth rocker arm 14, connecting the ninth rocker arm 14 to the base plate, and a torsion spring SP5, connected to the fifth rocker arm 10, is installed on the shaft 9B. The return spring SP4 and the torsion spring SP5 respectively perform the same function as the return spring SP1 and the torsion spring SP3 described above.

[0143] In this embodiment, the first movable part 6 is in the first locked position and the second control lever 5B is rotated to the position via the paddle 5Bb. Figure 10 In the indicated position (i.e., with the second movable part 7 in the second unlocked position), when the occupant operates the emergency unlocking device, the emergency unlocking device pulls the first drive arm DA1 via the second cable, thereby moving the first movable part 6 to the first unlocked position via the first control lever 4. Then, when the occupant operates the emergency unlocking device again, the ninth rocker arm 14 rotates clockwise via the second cable, thereby pushing the second movable part 7 via the lower surface of the third protrusion 14a, which in turn pushes the fifth rocker arm 10 to rotate around axis 9B. Next, the fifth rocker arm 10 moves the first movable part 6, which is in the first unlocked position, together with the first movable part 6, thereby rotating the sixth rocker arm 11 via the first movable part 6. Thus, the sixth rocker arm 11 unlocks the sliding door by operating the front and rear locks via the cable.

[0144] On the other hand, the second control lever 5B was not operated. Figure 10In the position shown, even if the occupant operates the emergency unlocking device and pulls the ninth rocker arm 14 via the first cable, the ninth rocker arm 14 cannot drive the fifth rocker arm 10 to rotate via the second movable part 7, and therefore cannot unlock the sliding door by controlling the front and rear locks via the sixth rocker arm 11. However, in this case, since the ninth rocker arm 14 itself can rotate, similar to the first embodiment described above, the fully open limit lock connected to the ninth rocker arm 14 can be operated by operating the emergency unlocking device, thereby enabling the door to be closed.

[0145] As described above, in this embodiment, similar to the previous embodiment, the occupant can unlock the door control device 100B by pulling the emergency unlocking device twice.

[0146] <Other Implementation Methods>

[0147] The preferred embodiments of this utility model have been described above, but the utility model is not limited thereto, and various modifications can be made without departing from the spirit of this utility model. In the above embodiments, the case of the door control device controlling the sliding door has been described, but it is not limited thereto. The door is not limited to a sliding door but can be a door with any operating mode.

[0148] In the first embodiment described above, the automatic opening and closing of the sliding door was explained using a sensor control device SW, but the implementation is not limited to this. The sensor control device SW is optional, and the door can also be opened manually by the user without the sensor control device SW, as in the second embodiment.

[0149] In the above embodiment, the emergency unlocking device is described as a handle protruding from the interior side of the vehicle door, but it is not limited thereto. The specific shape of the emergency unlocking device is not particularly limited, as long as it is a shape that is convenient for passengers to operate.

[0150] In the above embodiments, the emergency state is illustrated using collision and fire as examples, but it is not limited to these. What conditions are set as an emergency state, that is, under what conditions the electronic control device automatically releases the restriction on the operation of the second motor M2 from the locking mode, can be arbitrarily set by the vehicle manufacturer using the door control device.

[0151] In the above embodiment, the method by which the electronic control device detects the rotational position of the first motor M1 has been described, but it is not limited thereto. As long as it can detect that the first drive arm DA1 is pulled by the second cable, in addition to the rotor rotating as described above, a sensor can also be installed on the first motor M1, or a sensor for detecting the position of the first drive arm DA1, etc.

[0152] In the second embodiment described above, a second rocker arm 2A is provided instead of the second rocker arm 2 and the third rocker arm 3, but this is not a limitation. Even without a structure such as a second motor M2 and a second drive arm DA2, a third rocker arm for connecting to an emergency unlocking device and a second rocker arm for connecting to an external handle, etc., can be provided respectively. In this way, it is not necessary to provide a component that indirectly abuts the third rocker arm 3 against the first rocker arm 1, as in the second movable part 7 of the first embodiment; the third rocker arm can directly abut against the first rocker arm to drive the first rocker arm to rotate. In this case, the manufacturer of the vehicle using the door control device can provide a mechanism for setting the locking mode according to the actual situation.

[0153] 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.
