Description

Technical Field

[0001] This application relates to the field of vehicle sliding door technology, and in particular to a vehicle sliding door system and its control method, storage medium and electronic equipment. Background Technology

[0002] Current vehicle sliding door systems trigger the central locking system via an internal unlock handle, sending an unlock signal to the controller. This causes the controller to control multiple locks within the sliding door to unlock it. These locks are used to lock the sliding door in different states, including at least a front lock, a fully open retaining lock, and a rear closing lock. The front lock and rear closing lock lock the sliding door when it is closed. The fully open retaining lock locks the sliding door when it is fully open. Furthermore, when the sliding door is half-open, the clutch connected between the sliding door and the drive unit is engaged to lock the sliding door in the half-open state.

[0003] Current vehicle sliding door systems have multiple locking mechanisms, which increases the number of components and wiring complexity of the sliding door. This also makes the control process for opening and closing the sliding door more cumbersome. Furthermore, the locking method of locking the sliding door in a half-open state by engaging a clutch also increases vehicle energy consumption. Summary of the Invention

[0004] The purpose of this application is to overcome the shortcomings of existing vehicle sliding door systems and to provide a vehicle sliding door system with fewer components, a simple opening and closing control process, and lower energy consumption, as well as its control method, storage medium, and electronic equipment.

[0005] The technical solution of this application provides a vehicle sliding door system, including...

[0006] An electronic switch is used to send a signal to activate the sliding door;

[0007] A magnetic lock is used to lock a sliding door when it is in the closed position.

[0008] A drive device for driving a sliding door to slide, the drive device including a driver, a clutch and a locking mechanism, the clutch engaging when driving the sliding door to slide to transmit the torque of the driver to the sliding door, and the locking mechanism locking the sliding door through the clutch when the sliding door is in the open state;

[0009] An electronic control unit is used to receive the sliding door actuation signal and control the suction lock and the drive device to actuate according to the sliding door actuation signal to drive the sliding door to slide.

[0010] Furthermore, the clutch includes an active friction plate connected to the drive and a driven friction plate connected to the sliding door. The locking mechanism is disposed on one side of the driven friction plate. When the sliding door is in the open state, the locking mechanism locks the driven friction plate to lock the sliding door.

[0011] Furthermore, the electronic switch includes an interior door lock switch installed inside the vehicle and an exterior unlock switch that is linked to an exterior handle installed outside the sliding door.

[0012] Furthermore, it also includes an emergency unlocking handle installed on the sliding door. The emergency unlocking handle is mechanically linked to the magnetic lock, and pulling the emergency unlocking handle can trigger the mechanical structure to unlock the magnetic lock.

[0013] Furthermore, it also includes a child lock installed inside the vehicle. When the electronic control unit receives the sliding door actuation signal, if the child lock is in a locked state, it will not control the magnetic lock and the drive device to operate.

[0014] The technical solution of this application also provides a control method for the vehicle sliding door system as described above, including...

[0015] Steps to open the sliding door:

[0016] In response to the sliding door opening signal issued by the electronic switch, if the magnetic lock is in a locked state, the magnetic lock is unlocked.

[0017] After the clutch is engaged, if the locking mechanism is in a locked state, the locking mechanism is unlocked, and then the drive is used to open the sliding door.

[0018] The driver is controlled to soft stop until the sliding door is fully open or a stop signal from the sliding door is received.

[0019] After the locking mechanism is locked, the clutch is disengaged.

[0020] Sliding door closing steps:

[0021] In response to the sliding door closing signal issued by the electronic switch, the clutch is engaged, the locking mechanism is unlocked, and then the driver is used to close the sliding door.

[0022] The actuator is soft-stopped until the sliding door is closed.

[0023] After the locking mechanism is engaged to the locked state, the clutch is disengaged; or

[0024] The driver is controlled to soft stop until a stop signal from the sliding door is received.

[0025] After the locking mechanism is locked, the clutch is disengaged.

[0026] Furthermore, the vehicle sliding door system also includes a child lock installed inside the vehicle;

[0027] The response to the sliding door opening signal issued by the electronic switch also includes...

[0028] If the child lock is in the locked state, a door lock trigger prompt operation is performed.

[0029] Furthermore, the vehicle sliding door system also includes an emergency unlocking handle installed on the sliding door. The emergency unlocking handle is mechanically linked to the magnetic lock, and pulling the emergency unlocking handle can trigger the mechanical structure to unlock the magnetic lock.

[0030] The control method also includes

[0035] The technical solution of this application also provides an electronic device, including at least one processor; and,

[0036] A memory communicatively connected to the at least one processor; wherein,

[0037] The memory stores instructions that can be executed by the at least one processor to enable the at least one processor to perform the control method as described above.

[0038] The above technical solution has the following beneficial effects:

[0039] This application uses an electronic switch to directly send the sliding door actuation signal to the electronic control unit, which then controls the magnetic lock and drive device to drive the sliding door to slide. The sliding door actuation control process involves fewer components and is simpler.

[0040] This application only sets up a suction lock to lock the sliding door when it is closed. When the sliding door is open, the locking mechanism locks the clutch to achieve the locking of the sliding door, which reduces the number of lock components. At the same time, when the locking mechanism locks the clutch, the clutch can be in a de-energized state, which greatly reduces the energy consumption of the clutch. Attached Figure Description

[0062] Vehicle sliding door system:

[0063] The vehicle sliding door system in this application embodiment, such as Figure 1 , 2 As shown, including

[0064] Electronic switch 01 is used to send a signal to activate the sliding door;

[0065] The magnetic lock 02 is used to lock the sliding door when it is in the closed position.

[0066] The drive unit 03 is used to drive the sliding door to slide. The drive unit 03 includes a driver 31, a clutch 32 and a locking mechanism 33. The clutch 32 engages when driving the sliding door to slide so as to transmit the torque of the driver 31 to the sliding door. The locking mechanism 33 locks the sliding door through the clutch 32 when the sliding door is in the open state. The open state includes a fully open state and a half open state.

[0067] The electronic control unit 04 is used to receive the sliding door actuation signal and control the suction lock 02 and the drive device 03 to drive the sliding door to slide according to the sliding door actuation signal.

[0068] The vehicle sliding door system in this embodiment of the application is equipped with an electronic switch 01 to send sliding door operation signals, including but not limited to sliding door open signal, sliding door stop signal and sliding door close signal. The electronic switch 01 directly sends the sliding door operation signal to the electronic control unit 04, eliminating the central locking as a signal transmission intermediary, simplifying the sliding door system and improving the operation response efficiency.

[0069] In addition, the fully open retaining lock has been eliminated. By adding a locking mechanism 33, when the sliding door is in the open state, the locking mechanism 33 restricts the rotational freedom of the part of the structure that links the clutch and the sliding door, thereby locking the sliding door. With this configuration, the sliding door can be locked not only in the fully open state, but also in any position.

[0070] like Figure 2 As shown, the magnetic lock 02 is installed at the rear end of the sliding door and is used to lock the sliding door when it is in the closed state. When the rear end of the sliding door moves to the set locking position, the magnetic lock is controlled to engage and lock the sliding door. It should be noted that the magnetic lock 02 in this embodiment can be an existing magnetic lock, and specific examples can be found in the prior art magnetic lock structure. This application does not limit it in this regard.

[0071] Meanwhile, when the door is closed, the locking mechanism 33 can also lock the clutch, forming a double lock on the sliding door together with the magnetic lock 02 to ensure the locking security of the sliding door.

[0072] Preferably, in order to improve the locking strength of the sliding door in the closed state, a pin 05 is installed at the front end of the door. The pin 05 includes a post installed on the vehicle body and a slot installed on the sliding door. When the sliding door is in the closed state, the post is inserted into the slot to achieve mechanical locking of the sliding door.

[0073] The vehicle sliding door system in this embodiment has a simple structure, facilitates the control of the opening and closing of the door, improves the response speed of the door opening and closing, and reduces overall energy consumption.

[0074] In one embodiment, such as Figure 3 As shown, the clutch 32 includes an active friction plate (not shown) connected to the drive 31 and a driven friction plate 321 connected to the sliding door. The locking mechanism 33 is disposed on one side of the driven friction plate 321. When the sliding door is in the open state, the locking mechanism 33 locks the driven friction plate 321 to lock the sliding door.

[0075] Specifically, the locking mechanism 33 includes a positioning gear 331 and a locking rod 332. The positioning gear 331 has positioning teeth 3311 evenly arranged circumferentially, and the locking rod 332 has locking teeth 3321. The locking rod 332 is rotatably mounted in the clutch housing. When the locking teeth 3321 mesh with the positioning teeth 3311, the driven friction plate 321 is locked. The locking rod 332 is driven by a guide cam 333 and a drive motor 334. The drive motor 334 is connected to a worm gear 335, and the guide cam 333 is connected to a worm wheel 336. The worm gear 335 and the worm wheel 336 mesh, and the drive motor 334 drives the guide cam 333 to rotate after transmission through the worm gear 335 and the worm wheel 336.

[0076] One end of the locking rod 332 is provided with a locking tooth 3321, and the other end is provided with a support block 3322. The middle part of the locking rod 332 is provided with a rotating shaft 3323. The guide cam 333 pushes the support block 3322 to make the locking rod 332 rotate around the rotating shaft 3323, so that the locking tooth 3321 moves relative to the driven friction plate 321.

[0077] The support block 3322 is connected to a first elastic element 337 and a second elastic element 338 in the direction of movement. The first elastic element 337 is connected between the clutch housing and the support block 3322. One end of the second elastic element 338 is connected to the support block 3322, and the other end is connected to a guide block 339. The guide block 339 contacts the outer peripheral surface of the guide cam 333 to realize the linkage between the guide cam 333 and the locking rod 332.

[0078] The first elastic element 337 and the second elastic element 338 are used to maintain the engagement of the locking tooth 3321 and the positioning tooth 3311. Preferably, when the locking tooth 3321 and the positioning tooth 3311 are engaged, the second elastic element 338 is in a compressed and energy-storing state. Then, when the locking tooth 3321 and the positioning tooth 3311 are engaged, if the sliding door drives the driven friction plate 321 to rotate synchronously under the action of an external force, if the external force is large enough, it can push the locking tooth 3321 away from the driven friction plate 321. At this time, the support block 3322 compresses the first elastic element 337. During this process, the second elastic element 338 releases energy to assist in pushing the support block 3322 toward the first elastic element 337.

[0079] In one embodiment, the electronic switch 01 includes an interior door lock switch 11 installed inside the vehicle and an exterior unlock switch 12 that is linked to an exterior handle installed outside the sliding door.

[0080] Specifically, one or more interior door lock switches 11 can be provided, with at least one interior door lock switch 11 installed on the sliding door. The occupant sends a sliding door open signal, a sliding door stop signal, and a sliding door close signal through the interior door lock switch 11 on the sliding door. Preferably, an interior door lock switch 11 can also be provided at the driver's seat.

[0081] An external handle is installed on the outer surface of the sliding door. The external unlocking switch 12 can be hidden in the external handle. When the external handle is pulled, the external unlocking switch 12 is triggered, so that the external unlocking switch 12 sends a sliding door opening signal to the electronic control unit 104.

[0082] In one embodiment, an emergency unlocking handle 06 is also included, which is installed on the sliding door. The emergency unlocking handle 06 is mechanically linked to the magnetic lock 02. Pulling the emergency unlocking handle 06 can trigger the mechanical unlocking mechanism to unlock the magnetic lock 02.

[0083] Specifically, such as Figure 4 As shown, the magnetic lock 02 includes a pawl 21 and a ratchet 22 that cooperate with each other. When locked, the pawl 21 rotates to the locking angle to lock the ratchet 22. When unlocked, the pawl 21 rotates to the unlocking angle to separate the ratchet 22 and the pawl 21. The emergency unlock handle 06 includes a handle 61, a lever 62 and a cable 63 connecting the handle 61 and the lever 62. The handle 61 is installed on the inside of the sliding door. The lever 62 is connected to the pawl 21 of the magnetic lock 02. When the user pulls the handle 61, the lever 62 can drive the pawl 21 to rotate, thereby unlocking the magnetic lock 02.

[0084] In this embodiment, the emergency unlocking handle 06 is installed on the inside of the sliding door. The emergency unlocking handle 06 adopts a mechanical structure and is linked with the suction lock 02. In an emergency, the suction lock 02 can be forcibly opened by the emergency unlocking handle 06 to realize emergency door opening.

[0085] In one embodiment, a child lock 07 installed inside the vehicle is also included. When the electronic control unit 04 receives the sliding door actuation signal, if the child lock 07 is in a locked state, it will not control the magnetic lock 02 and the drive device 03 to operate.

[0086] This application embodiment installs a child lock 07 inside the vehicle. The child lock 07 can be an electronic lock. When the child lock 07 is locked, it sends a child lock locking signal to the electronic control unit 04. When the electronic control unit 04 receives the child lock locking signal, even if it receives the sliding door actuation signal sent by the electronic switch 01, it does not control the magnetic lock 02 and the drive device 03 to operate, thereby realizing the child lock safety function.

[0087] Control methods for vehicle sliding door systems:

[0088] The technical solution of this application also provides a control method for the vehicle sliding door system of the aforementioned embodiments, such as... Figure 5 , 6 As shown, including

[0089] Steps to open the sliding door:

[0090] Step S501: In response to the sliding door opening signal issued by the electronic switch, if the magnetic lock is in the locked state, then execute step S502 and then step S503; otherwise, execute step S503 directly.

[0091] Step S502: Control the unlocking of the magnetic lock;

[0092] Step S503: Control the clutch to engage;

[0093] Step S504: If the locking mechanism is in a locked state, then execute step S505 and then step S506; otherwise, execute step S506 directly.

[0094] Step S505: Control the locking mechanism to unlock;

[0095] Step S506: Control the driver to open the sliding door;

[0096] Step S507: Control the driver to soft stop until the sliding door is fully open or a sliding door stop signal is received;

[0097] Step S508: After the locking mechanism is locked, the clutch is disengaged.

[0098] Specifically, when the sliding door opens signal is received from the electronic switch, if the magnetic lock is detected to be locked, it means that the sliding door is closed. Then, step S502 is executed first to unlock the magnetic lock, and then step S503 is executed. If the magnetic lock is unlocked, it means that the sliding door is half open, and step S503 is executed directly.

[0099] Step S503 controls the driven friction plate of the clutch to engage with the driving friction plate, linking the drive unit with the sliding door. Then, step S504 determines if the locking mechanism is locked. If so, step S505 unlocks the locking mechanism before step S506 starts the drive unit to open the sliding door. Otherwise, step S506 directly starts the drive unit to open the sliding door. This continues until the sliding door is fully open or a stop signal is received. Then, step S507 soft-stops the drive unit to prevent a sudden stop. After the sliding door stops, step S508 locks the driven friction plate with the locking mechanism to restrict the sliding door's movement before disengaging the clutch. This allows the sliding door to be locked in any open position, reducing clutch energy consumption. Engaging the clutch before unlocking the locking mechanism ensures the sliding door is locked before the drive unit starts.

[0100] Sliding door closing steps:

[0101] Step S601: In response to the sliding door closing signal issued by the electronic switch, after the clutch is engaged, the locking mechanism is unlocked, and then the drive is controlled to close the sliding door.

[0102] Step S602: Until the sliding door is in the closed state, control the drive to soft stop;

[0103] Step S603: After the control lock is engaged to the locked state, control the clutch to disengage; or

[0104] Step S604: Until a stop signal from the sliding door is received, control the driver to soft stop;

[0105] Step S605: After the locking mechanism is locked, the clutch is disengaged.

[0106] Specifically, when a sliding door closing signal is received from the electronic switch, step S601 is executed: first, the clutch is engaged, then the locking mechanism is unlocked to prevent the sliding door from sliding after the locking mechanism is unlocked. Then, the drive unit is controlled to close the sliding door. Once the sliding door has slid to the closed state, steps S602 and S603 are executed: first, the drive unit is soft-stopped, then the engagement lock is engaged to the locked state, and finally, the driven and driving friction plates of the clutch are disengaged. Alternatively, if a sliding door stop signal is received before the sliding door reaches the closed state, steps S604 and S605 are executed: first, the drive unit is soft-stopped, then the locking mechanism is locked, and finally, the driven and driving friction plates of the clutch are disengaged.

[0107] Optionally, when the sliding door slides to the closed state, after controlling the clutch to disengage in step S603, the locking mechanism can be further controlled to lock the clutch, thereby achieving double locking of the sliding door in the closed state.

[0108] The opening and closing steps of the sliding door in this embodiment only require controlling the engagement of the latch and the clutch. The control steps are simple and can achieve a rapid response in the operation of the sliding door.

[0109] In one embodiment, the vehicle sliding door system also includes a child lock located inside the vehicle;

[0110] The steps for opening a sliding door are as follows: Figure 7 As shown, it specifically includes:

[0111] Step S701: In response to the sliding door opening signal from the electronic switch, if the child lock is in the locked state, proceed to step S702; otherwise, proceed to step S703.

[0112] Step S702: Execute the door lock trigger prompt operation;

[0113] Step S703: If the latch is in the locked state, then execute step S704 and then step S705; otherwise, execute step S705 directly.

[0114] Step S704: Control the unlocking of the magnetic lock;

[0115] Step S705: After controlling the clutch to engage;

[0116] Step S706: If the locking mechanism is in a locked state, then execute step S707 and then step S708; otherwise, execute step S708 directly.

[0117] Step S707: Control the locking mechanism to unlock;

[0118] Step S708: Control the drive to open the sliding door;

[0119] Step S709: Control the driver to soft stop until the sliding door is fully open or a sliding door stop signal is received;

[0120] Step S710: After the locking mechanism is locked, the clutch is disengaged.

[0121] In this embodiment, the vehicle sliding door system is equipped with a child lock. When the sliding door is opened, if the child lock is locked, it is considered that the child has misoperated. At this time, the door lock trigger prompt operation is performed. The reminder can be achieved by emitting a prompt sound, flashing an indicator light, etc., to remind the user to pay attention to the child or to release the child lock before opening the door.

[0122] In one embodiment, the vehicle sliding door system further includes an emergency unlocking handle installed on the sliding door. The emergency unlocking handle is mechanically linked to the magnetic lock, and pulling the emergency unlocking handle can trigger the mechanical structure to unlock the magnetic lock.

[0123] The control method is as follows Figure 8 As shown, it also includes

[0124] Step S801: In response to the emergency unlock handle being pulled, if the child lock is in the locked state, then

[0125] Step S802: Control the clutch to engage;

[0126] Step S803: Control the magnetic lock to engage to the locked state;

[0127] Step S804: After receiving the door lock signal, control the clutch to disengage.

[0128] In this embodiment, the vehicle sliding door system is equipped with an emergency unlock handle, which can mechanically release the locking mechanism of the magnetic lock. To prevent children from accidentally triggering the emergency unlock handle and causing the sliding door to open, if the emergency unlock handle is pulled while the child lock is in the locked state, the sliding door needs to be locked immediately.

[0129] When the emergency unlock handle is pulled, the status of the magnetic lock can be detected. If the magnetic lock is forcibly unlocked without receiving an unlock command, and the child lock is detected to be locked, the clutch is engaged to lock the sliding door in an emergency. Then, the magnetic lock is engaged again to return to the locked state, and the clutch is disengaged. This ensures that the sliding door cannot be opened when the emergency unlock handle is pulled while the child lock is locked, thus guaranteeing the effectiveness of the child lock.

[0130] Preferably, after the clutch is engaged in step S802 or while step S802 is being executed, if the locking mechanism is in the unlocked state, the locking mechanism is locked until step S804 is executed and the clutch is disengaged. The locking mechanism remains in the locked state to ensure the effective locking of the sliding door.

[0131] The technical solution of this application also provides a storage medium that stores computer instructions. When the computer executes the computer instructions, it is used to execute the control method of the vehicle sliding door system in any of the foregoing embodiments.
