[0067] Sliding door system:

[0068] The sliding door system in the embodiment of the present application, such as Figure 1 、 2 Shown, including

[0069] Electronic switch 101, used to send a sliding door actuation signal;

[0070] A suction lock 102 is used to lock the sliding door when the sliding door is in a closed state;

[0071] a cable winder 103 for connecting to the sliding door;

[0072] A driving assembly 104 is connected to the winder 103 and is used to drive the winder 103 to rotate so as to drive the sliding door to slide;

[0073] a locking mechanism 105 for locking the cable winder 103 to lock the sliding door when the sliding door is in an open state;

[0074] The electronic control unit 106 is configured to receive a sliding door actuation signal and control the suction lock 102 and the driving assembly 104 to actuate the sliding door according to the sliding door actuation signal so as to drive the sliding door to slide.

[0075] The sliding door system in the embodiment of the present application is provided with an electronic switch 101 that transmits sliding door actuation signals, including but not limited to sliding door opening signals, sliding door stopping signals, and sliding door closing signals. Electronic switch 101 can be triggered by pressing, touching, or voice commands. In response to the triggering of electronic switch 101, electronic switch 101 transmits the corresponding sliding door actuation signal to electronic control unit 106, eliminating the central locking system as a signal transmission intermediary. This simplifies the sliding door system and improves actuation response efficiency.

[0076] In addition, the sliding door system eliminates the clutch and the fully open lock. The drive assembly 104 directly drives the cable winder 103 to rotate to drive the sliding door to slide, and a locking mechanism 105 is added to lock the cable winder 103. During the opening and closing process of the sliding door, the locking mechanism 105 is in the unlocked state, separating the locking mechanism 105 from the cable winder 103. The drive assembly 104 drives the cable winder 103 to rotate to drive the sliding door to slide. When the sliding door is in the fully open state or in the hill-holding state and receives a sliding door stop signal, the drive assembly 104 stops driving the cable winder 103. At the same time, the locking mechanism 105 switches to the locked state, locking the cable winder 103. By restricting the rotation of the cable winder 103, the sliding door is locked in the open state of the fully open state or the hill-holding state.

[0077] like Figure 2 As shown, the suction lock 102 is installed at the rear end of the sliding door and is used to lock the sliding door when the sliding door is in the closed state. When the rear end of the sliding door moves to the set locking position, the suction lock is controlled to be sucked in and lock the sliding door. It should be noted that the suction lock 102 in the embodiment of the present application can adopt an existing suction lock. For details, please refer to the suction lock structure of the prior art, and this application is not limited to this.

[0078] Preferably, when the sliding door is in a closed state, the locking mechanism 105 can also lock the cable winder 103, thereby forming a double locking of the sliding door together with the suction lock 102 to ensure the locking safety of the vehicle door.

[0079] Preferably, in order to improve the locking strength of the sliding door in the closed state, a latch 107 is installed at the front end of the vehicle door. The latch 107 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.

[0080] The vehicle sliding door system in the embodiment of the present application has a simple structure, is easy to control the opening and closing of the door, improves the response speed of the door opening and closing, and reduces overall energy consumption.

[0081] In one embodiment, Figure 3 As shown, the winding device 103 is provided with a positioning gear 01;

[0082] The locking mechanism 105 includes a locking rod 02 movably mounted on one side of the positioning gear 01 . The locking rod 02 is provided with a locking tooth 21 . When the locking tooth 21 is engaged with the positioning gear 01 , the winder 103 is locked.

[0083] Specifically, if Figure 6As shown, the winding device 103 is also provided with a driving gear 03, which is coaxially connected to the positioning gear 01 and rotates synchronously. The driving assembly 104 includes a first driving motor 04 and a first driving worm 05, which meshes with the driving gear 03 to drive the winding device 103 to rotate as a whole.

[0084] like Figure 3 、 4 As shown, the locking mechanism 105 also includes a lock rod driving assembly 06 for driving the lock rod 02 to move. The middle part of the lock rod 02 is rotatably mounted on the mounting bracket 07 through a pin 22. The locking tooth 21 is arranged at one end of the lock rod 02, and the lock rod driving assembly 06 is arranged at the other end of the lock rod 02.

[0085] like Figure 5 As shown, the locking rod drive assembly 06 includes a second driving motor 61, a second driving worm 62, a transmission worm gear assembly and a swinging member 63; the second driving worm 62 is connected to the output shaft of the second driving motor 61, the transmission worm gear assembly is connected between the second driving worm 62 and the swinging member 63, the swinging member 63 is fixedly connected to the locking rod 02, and the second driving motor 61 drives the swinging member 63 to swing through the second driving worm 62 and the transmission worm gear assembly to drive the locking rod 02 to move, thereby driving the locking tooth 311 to approach or move away from the positioning gear 01.

[0086] The transmission worm gear assembly includes a worm gear 64 and a sector gear 65. The worm gear 64 is provided with a coaxial first gear 641 and a second gear 642. The sector gear 65 includes an arcuate tooth set 651 provided on the arcuate outer surface and an inner ring tooth set 652 provided on the inner wall of the shaft hole. The first gear 641 is meshed with the second driving worm 62, and the arcuate gear set 651 is meshed with the second gear 642.

[0087] A rotating gear 631 is provided on the swing shaft of the swing member 63 . The rotating gear 631 is installed in the shaft hole of the sector gear 65 and meshes with the inner ring gear set 652 .

[0088] In the transmission worm gear assembly, the second driving worm 62 drives the worm wheel 64 to rotate through the first gear 641 , the worm wheel 64 drives the sector gear 65 to rotate through the second gear 642 , and the sector gear 65 drives the swing member 63 to swing around its swing axis through the inner ring gear set 652 .

[0089] The swing member 63 is provided with a connecting post 632, which is parallel to the swing axis of the swing member 63. The lock rod 02 is provided with a connecting hole 23, and the connecting post 632 is inserted into the connecting hole 23 to connect the lock rod 02. Figure 3 、 4As shown, one end of the locking rod 02 is provided with a locking tooth 21 and is also connected to an energy storage reset assembly 08; one end of the energy storage reset assembly 08 is hinged to the locking rod 02, and the other end is hinged to the mounting bracket 07. When the locking rod 02 rotates and drives the locking tooth 21 away from the positioning gear 01, the energy storage reset assembly 08 stores energy.

[0090] The energy storage reset assembly 08 includes a pin 81, a spring 82, a first connecting member 83 and a second connecting member 84;

[0091] The first connecting member 83 is provided with a first through hole, the second connecting member 84 is provided with a second through hole, and both ends of the pin 81 are provided with a first limiting member 811 and a second limiting member 812, respectively. One end of the pin 81 extends into the first through hole and is limited by the first limiting member 811, and the other end extends into the second through hole and is limited by the second limiting member 812.

[0092] The first connecting member 83 is hinged to the mounting bracket 07 via a first pin 85 , the second connecting member 84 is hinged to the locking rod 02 via a second pin 86 , and the spring 82 is sleeved on the pin 81 and abuts between the first connecting member 83 and the second connecting member 84 .

[0093] When the locking rod 02 is unlocked, the energy storage reset assembly 08 drives the second connecting member 84 to squeeze the spring 82 to store energy; when the locking rod 02 is locked, the locking rod 02 drives the second connecting member 84 away from the first connecting member 83, and the spring 82 releases energy to push the second connecting member 84 to squeeze the locking tooth 21 toward the positioning gear 01, providing auxiliary driving force for the locking rod 02 to lock the positioning gear 01.

[0094] In one embodiment, the electronic switch 101 includes an interior door lock switch 09 installed in the vehicle, and an exterior door unlock switch 010 linked to an exterior handle installed outside the sliding door.

[0095] Specifically, one or more interior door lock switches 09 can be set, and at least one interior door lock switch 09 can be installed on the sliding door. The occupants send sliding door opening signals, sliding door stop signals and sliding door closing signals through the interior door lock switch 09 on the sliding door. Preferably, an interior door lock switch 09 can also be set at the driving position.

[0096] An external handle is installed on the outer surface of the sliding door, and the external unlocking switch 010 can be hidden in the external handle. When the external handle is pulled, the external unlocking switch 010 is triggered, so that the external unlocking switch 010 sends a sliding door opening signal to the electronic control unit 106.

[0097] In one embodiment, Figure 2As shown, an emergency unlocking handle 108 is also included which is installed on the sliding door. The emergency unlocking handle 108 is linked to the suction lock 102 through a mechanical structure. Pulling the emergency unlocking handle 108 can trigger the mechanical structure to unlock the suction lock 102 .

[0098] Specifically, if Figure 7 As shown, the suction lock 102 includes a pawl 011 and a ratchet 012 that cooperate with each other. When locking, the pawl 011 rotates to a locking angle to lock the ratchet 012. When unlocking, the pawl 011 rotates to an unlocking angle to separate the ratchet 012 and the pawl 011. The emergency unlocking handle 108 includes a handle 013, a pull rod 014 and a cable 015 connected between the handle 013 and the pull rod 014, wherein the handle 013 is installed on the inner side of the sliding door, and the pull rod 014 is connected to the pawl 011 of the suction lock 102. When the user pulls the handle 013, the pull rod 014 can drive the pawl 011 to rotate to unlock the suction lock 102.

[0099] In the embodiment of the present application, the emergency unlocking handle 108 is installed on the inner side of the sliding door. The emergency unlocking handle 108 adopts a mechanical structure to be linked with the suction lock 102. In an emergency, the emergency unlocking handle 108 can be used to forcibly open the suction lock 102 to achieve emergency door opening.

[0100] In one embodiment, a child lock 109 is further provided in the vehicle. When the electronic control unit 106 receives the sliding door actuation signal, if the child lock 109 is in a locked state, the suction lock 102 and the driving assembly 104 are not controlled to actuate.

[0101] In the embodiment of the present application, a child lock 109 is set in the vehicle. The child lock 109 can be set as an electronic lock. When the child lock 109 is locked, a child lock locking signal is sent to the electronic control unit 106. When the electronic control unit 106 receives the child lock locking signal, even if it receives the sliding door actuation signal sent by the electronic switch 101, it does not control the suction lock 102 and the drive component 104 to be actuated, thereby realizing the child lock safety function.

[0102] Control method of sliding door system:

[0103] In an embodiment of the present application, a control method of the sliding door system as described above is provided. Figure 8 、 9 Shown, including

[0104] Sliding door opening steps:

[0105] Step S801: In response to the sliding door opening signal sent by the electronic switch, determine whether the suction lock is in the locked state. If so, execute step S802 and then step S803; otherwise, execute step S803 directly;

[0106] Step S802: controlling the pull-in lock to unlock;

[0107] Step S803: If the locking mechanism is in the locked state, execute step S804 and then execute step S805; otherwise, execute step S805;

[0108] Step S804: controlling the locking mechanism to unlock;

[0109] Step S805: Control the driving assembly to drive the sliding door to open until the sliding door is in a fully open state or a sliding door stop signal is received, and control the driving assembly to soft stop;

[0110] Step S806: Control the locking mechanism to lock.

[0111] Specifically, when step S801 receives the sliding door opening signal sent by the electronic switch, it first determines whether the suction lock is in a locked state. This is because if the sliding door is in a closed state at this time, the suction lock is in a locked state, so it is necessary to first execute step S802 to control the suction lock to unlock; if the sliding door is in a half-open state at this time, the suction lock will not affect the sliding of the sliding door, so step S803 can be executed directly.

[0112] Step S803 further determines whether the locking mechanism is in a locked state. This is because, if the sliding door is in a closed state, the sliding door is locked by a suction lock, and the locking mechanism may be in an unlocked state. At this time, step S805 can be executed directly; if the sliding door is in a half-open state, the locking mechanism is in a locked state. At this time, step S804 needs to be executed first to control the locking mechanism to unlock before executing step S805.

[0113] Preferably, if the sliding door system is configured such that the locking mechanism and the suction lock jointly lock the sliding door when the sliding door is in the closed state, step S803 does not need to be executed, and step S804 is directly executed followed by step S805.

[0114] Step S805 controls the driving of the driving component, and drives the sliding door to slide by driving the winder until the sliding door is in a fully open state or a sliding door stop signal is received, and controls the driving component to soft stop to prevent the sliding door from stopping suddenly; then, after the sliding door stops sliding, step S806 is executed to control the locking mechanism to lock the winder and lock the sliding door in the current position.

[0115] Sliding door closing steps:

[0116] Step S901: In response to the sliding door closing signal sent by the electronic switch, the locking mechanism is controlled to unlock, and then the driving assembly is controlled to drive the sliding door to close;

[0117] Step S902: until the sliding door is in the closed state, the driving assembly is controlled to soft stop, and the suction lock is controlled to be sucked into the locked state; or

[0118] Step S903: until a sliding door stop signal is received, the driving assembly is controlled to soft stop, and the locking mechanism is controlled to lock.

[0119] Specifically, in step S901, when the sliding door is closed and the locking mechanism is locked, the locking mechanism is first unlocked and the drive assembly is controlled to close the sliding door. If the sliding door is closed or a sliding door stop signal is received, the drive assembly is controlled to soft stop:

[0120] If the sliding door is closed, in addition to controlling the drive assembly to a soft stop, the latch must also be controlled to engage and lock the door. If the sliding door is closed, a sensor switch can be set at the fully closed position. When the sensor switch is triggered, a signal indicating the fully closed position is sent to the electronic control unit.

[0121] Preferably, if the sliding door system is configured such that the locking mechanism and the suction lock jointly lock the sliding door when the sliding door is in a closed state, then after step S902 , the locking mechanism is controlled to lock, so as to achieve joint locking of the suction lock and the locking mechanism.

[0122] If a sliding door stop signal is received, the drive assembly is controlled to softly stop, and the locking mechanism is also controlled to lock to lock the sliding door in the current position.

[0123] The steps for opening and closing the sliding door in the embodiment of the present application only require controlling the actuation of the suction lock and the locking mechanism. The control steps are simple and can achieve rapid response of the sliding door actuation.

[0124] In one embodiment, the vehicle sliding door system further includes a child lock disposed inside the vehicle;

[0125] Sliding door opening steps, such as Figure 10 As shown, specifically including:

[0126] Step S1001: In response to the sliding door opening signal sent by the electronic switch, if the child lock is in the locked state, execute step S1002; otherwise, execute step S1003;

[0127] Step S1002: Execute door lock trigger prompt operation;

[0128] Step S1003: Determine whether the pull-in lock is in a locked state. If so, execute step S1004 and then step S1005; otherwise, execute step S1005 directly.

[0129] Step S1004: controlling the pull-in lock to unlock;

[0130] Step S1005: If the locking mechanism is in the locked state, execute step S1006 and then execute step S1007; otherwise, execute step S1007 directly;

[0131] Step S1006: controlling the locking mechanism to unlock;

[0132] Step S1007: Control the driving assembly to drive the sliding door to open until the sliding door is in a fully open state or a sliding door stop signal is received, and then control the driving assembly to soft stop;

[0133] Step S1008: Control the locking mechanism to lock.

[0134] In an embodiment of the present application, the sliding door system is equipped with a child lock. If the child lock is in a locked state when the sliding door opening signal is received, it is considered that the child has operated it incorrectly. At this time, the door lock trigger prompt operation is executed. The reminder can be achieved by emitting a prompt sound, flashing an indicator light, etc., to remind the user to pay attention to the children or release the child lock before opening the car door.

[0135] In one embodiment, the sliding door system further includes an emergency unlocking handle mounted on the sliding door, the emergency unlocking handle being linked to the suction lock via a mechanical structure, and pulling the emergency unlocking handle can trigger the mechanical structure to unlock the suction lock;
