For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0070] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0071] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings.

[0073] Figure 1 It is a schematic structural diagram of a self-priming side door lock according to an embodiment of the present disclosure. Figure 2 It is a schematic diagram of the internal structure of a self-priming side door lock according to an embodiment of the present disclosure.

[0074] like Figure 1 and Figure 2 As shown, the self-priming side door lock of the present disclosure may include a lock body 101, which can be formed as a shell of the self-priming side door lock, and accordingly, the lock tongue component 102 and the suction assembly 200 and other components can be arranged in the lock body 101. When the self-priming side door lock of the present disclosure is used, the lock body 101 can be fixed to components such as a vehicle door, so that the vehicle door can be locked by the self-priming side door lock.

[0075] The self-priming side door lock may also include a bolt component 102, which is rotatably arranged on the lock body 101 and includes a fully locked position, a half-locked position and an unlocked position. That is, when the bolt component 102 rotates, it can move to at least one of these positions. Specifically, the rotation direction of the bolt component 102 includes a locking direction and an unlocking direction, and the locking direction is the opposite rotation direction to the unlocking direction, wherein the locking direction is the direction in which the bolt component 102 rotates toward the fully locked position, for example, when the bolt component 102 moves from the unlocked position to the half-locked position, or from the half-locked position to the fully locked position, the rotation direction of the bolt component 102 is the locking direction; on the other hand, the unlocking direction is the direction in which the bolt component 102 rotates toward the unlocked position; for example, when the bolt component 102 moves from the fully locked position to the half-locked position, or from the half-locked position to the unlocked position, the rotation direction of the bolt component 102 is the unlocking direction.

[0076] The self-priming side door lock of the present disclosure may further include a suction assembly 200, which is disposed on the lock body 101 and can drive the lock tongue component 102 to rotate along a locking direction, thereby locking the self-priming side door lock of the present disclosure.

[0077] More preferably, the suction component 200 may include a suction motor 201, which is fixed to the lock body 101 and is used to provide suction power, so that the self-priming side door lock can be locked through the suction power provided by the suction motor 201.

[0078] Specifically, the suction component 200 can also include a reduction mechanism 210 and a driving component 220, wherein the reduction mechanism 210 is arranged on the lock body 101 and is transmission-connected to the suction motor 201; the driving component 220 is connected to the reduction mechanism 210 and is driven to rotate by the reduction mechanism 210, that is, the reduction mechanism 210 of the present disclosure can receive the power provided by the suction motor 201, and provide the power to the driving component 220 after torque increase, so that the driving component 220 can drive the lock tongue component 102 to rotate along the locking direction.

[0079] That is to say, when the self-priming side door lock of the present invention is in use, it can be locked by the power provided by the suction assembly 200. In addition, the lock tongue component can be rotated in the unlocking direction by the reset force provided by the reset spring, so that the self-priming side door lock is unlocked. Of course, the self-priming side door lock can also be unlocked by the following components such as the ice-breaking pull rod 103, and this structure will be described in detail below.

[0080] Specifically, when the suction motor 201 rotates in the first direction and causes the drive assembly 220 to rotate, the lock tongue component 102 is driven to rotate in the locking direction. In addition, when the suction motor 201 rotates in the second direction, the drive assembly 220 can be out of contact with the lock tongue component 102.

[0081] The following will be combined Figures 3 to 7 The structure of the suction assembly 200 of the present disclosure is described in detail.

[0082] like Figures 2 to 7 As shown, the output shaft of the suction motor 201 is provided with a worm, the reduction mechanism 210 includes a worm wheel, and the worm is drivingly connected with the worm wheel, thereby realizing the first stage reduction of the suction component 200.

[0083] In addition, the speed reduction mechanism 210 includes a ring gear 211, a sun gear 212, and planetary gears 213. In other words, the speed reduction mechanism 210 of the present disclosure can be formed as a planetary gear structure.

[0084] Specifically, the ring gear 211 has a accommodating space, and the inner wall surface of the accommodating space of the ring gear 211 (or the inner wall surface forming the accommodating space) is formed with an internal gear; the sun gear 212 is rotatably arranged on the ring gear 211 and is located in the accommodating space, and the sun gear 212 disclosed in the present invention can be driven by a worm gear drive device, especially, the sun gear 212 and the worm gear are connected to the same rotating shaft and have the same rotating axis; the planetary gear 213 is transmission connected to the sun gear 212 and the internal gear; thus, when the sun gear 212 is driven by the worm gear, the planetary gear 213 itself (or the axis of the planetary gear 213) can rotate along the rotating axis of the sun gear 212.

[0085] In a preferred embodiment, the number of the planetary gears 213 is at least two, and more preferably, the number of the planetary gears 213 is three, so that the planetary gear structure of the present disclosure can operate more stably.

[0086] In one embodiment, the driving assembly 220 includes a driving rod 221, at least part of which is formed as the axle of the planetary gear 213. In other words, the driving rod 221 is formed as the planetary wheel carrier of the above-mentioned planetary gear structure, and the planetary gear structure of the present disclosure outputs power to the outside through the planetary wheel carrier.

[0087] In the present disclosure, the driving assembly 220 also includes a suction rod 222, one end of which is rotatably disposed on the driving rod 221; the other end of the suction rod 222 cooperates with the lock tongue component 102 and pushes the lock tongue component 102 to rotate along the locking direction.

[0088] Therefore, the self-priming side door lock disclosed in the present invention reduces the driving wire by fixing the closing motor on the lock body, which can save costs, improve matching, and improve assembly efficiency.

[0089] In the present disclosure, the lock tongue component 102 includes a lock tongue first feature 102A, and the surface of the lock tongue first feature 102A cooperating with the suction rod 222 is formed as a concave arc-shaped groove, and at least a portion of the suction rod 222 is located in the concave arc-shaped groove. Therefore, when the suction rod 222 pushes the lock tongue component 102 to rotate, the suction rod 222 will not easily disengage from the arc-shaped groove, thereby improving the stability of the self-priming side door lock during the unlocking process.

[0090] In addition, when the suction pull rod 222 drives the lock tongue component 102 to rotate in the locking direction, the suction pull rod 222 is guided by the feature formed by the inner wall of the lock body 101, so that during the locking process, the suction pull rod 222 can stably / reliably contact the first feature 102A of the lock tongue. In a preferred embodiment, the feature formed by the inner wall of the lock body 101 can be a groove feature or a convex feature, which is not limited in the present disclosure. Moreover, since the suction pull rod 222 can be guided by the lock body 101, it is no longer necessary to set a spring or other equipment at the rotation axis of the suction pull rod 222, which reduces the number of parts, saves costs, and improves reliability.

[0091] The gear ring 211 is configured to be rotatable relative to the lock body 101; when the gear ring 211 is restricted so as to be unable to rotate relative to the lock body 101 (for example, when the gear ring 211 is unable to rotate relative to the lock body 101 by a lock pin or a clutch structure, etc.), the suction motor 201 can drive the driving rod 221 to rotate. On the other hand, when the gear ring 211 is configured to be able to rotate relative to the lock body 101, when the suction motor 201 rotates, the gear ring 211 will rotate, and accordingly, the driving rod 221 will not rotate, and naturally cannot drive the lock tongue component 102 to lock.

[0092] like Figure 3 and Figure 4As shown, the self-priming side door lock of the present disclosure further includes an ice-breaking rod portion 103, which is rotatably arranged on the lock body 101, and when the ice-breaking rod portion 103 is driven to rotate, it can drive the lock tongue component 102 to rotate along the unlocking direction.

[0093] Specifically, the ice-breaking rod portion 103 includes an ice-breaking rod first feature 103A, which is formed as an arm of the ice-breaking rod portion 103, and the ice-breaking rod first feature 103A is used to connect the pull line, so that the ice-breaking rod portion 103 can be driven to rotate by the pull line. In addition, the ice-breaking rod portion 103 can also include an ice-breaking rod second feature 103B, and the ice-breaking rod second feature 103B is also formed as an arm of the ice-breaking rod portion 103. When the ice-breaking rod portion 103 is driven to rotate, the ice-breaking rod second feature 103B can cooperate with the lock tongue component 102 and drive the lock tongue component 102 to rotate in the unlocking direction.

[0094] That is to say, when the door of the motor vehicle is covered with ice and snow, and the self-priming side door lock cannot be opened due to the elastic force provided by the return spring, the ice-breaking rod part 103 can provide a greater unlocking force to the lock tongue part 102, so that the door of the motor vehicle can break the ice outside and be opened.

[0095] In a preferred embodiment, when the suction motor 201 rotates along the second direction, the suction rod 222 is also used to drive the ice-breaking rod part 103 to move, so that the locking tongue component 102 rotates along the unlocking direction.

[0096] Specifically, the suction rod 222 can also apply a force to the second feature 103B of the ice-breaking rod, and enable the ice-breaking rod part 103 to drive the lock tongue component 102 to rotate along the unlocking direction, thereby realizing the ice-breaking and unlocking operation of the self-priming side door disclosed in the present invention.

[0097] Figure 8 It is a schematic structural diagram of a pawl assembly of a self-priming side door lock according to an embodiment of the present disclosure.

[0098] In this disclosure, Figure 8 As shown, the self-priming side door lock also includes: a pawl assembly 300 and an unlocking rod 104 and other components.

[0099] The pawl assembly 300 is used to limit the lock tongue component 102 in a fully locked position and a semi-locked position; wherein the pawl assembly 300 may include a first pawl 310 and a second pawl 320, wherein the first pawl 310 can cooperate with the lock tongue component 102 to keep the lock tongue component in the fully locked position, and the second pawl 320 cooperates with the lock tongue component 102 to keep the lock tongue component 102 (for example, cooperates with a raised feature on the lock tongue component 102) in the semi-locked position.

[0100] The unlocking lever 104 is rotatably disposed on the lock body 101 and is used to drive the pawl assembly 300 to move so that the pawl assembly 300 releases the lock tongue component 102. Specifically, the unlocking lever 104 can push the second pawl 320 to move, and at this time, the second pawl 320 can drive the first pawl 310 to move, so that the lock tongue component 102 is unlocked.

[0101] Fig. 9 It is a structural diagram of a central control device 400 according to an embodiment of the present disclosure.

[0102] like Fig. 9 As shown, the self-priming side door lock may further include a central control device 400, which includes a central control motor 401 and a central control transition rod 403, wherein the central control transition rod 403 may be engaged with or disengaged from the unlocking rod 104 by driving the central control motor 401.

[0103] Correspondingly, when the central control transition rod 403 is engaged with the unlocking rod 104, the central control motor 401 can drive the unlocking rod 104 to rotate and unlock the self-priming side door lock; on the other hand, when the central control transition rod 403 is disengaged from the unlocking rod 104, the central control motor 401 cannot drive the unlocking rod 104 to rotate, and at this time the central control device 400 cannot unlock the self-priming side door lock.

[0104] Specifically, if Fig. 9 As shown, the central control motor 401 can drive the central control worm wheel 402 to rotate. When the central control worm wheel 402 rotates in a first preset direction and the central control transition rod 403 is engaged with the unlocking rod 104, the central control device can drive the unlocking rod 104 to rotate. When the central control worm wheel 402 rotates in a second preset direction different from the first preset direction, the central control worm wheel 402 can drive the central control transition rod 403 and drive the central control transition rod 403 to a position disengaged from the unlocking rod 104, thereby the central control device 400 is in a failed state.

[0105] In addition, when the central control device 400 is in a failed state, it cannot be unlocked by the outward pull rod 105, that is, the outward pull rod 105 can drive the central control worm gear 402 to rotate, and drive the unlocking lever 104 to rotate through the rotation of the central control worm gear 402.

[0106] The self-priming side door lock of the present invention further includes an unlocking gear 106. When the unlocking gear 106 is driven and rotated, it can also drive the unlocking rod 104 to rotate, thereby unlocking the self-priming side door lock. In particular, after the self-priming side door lock of the present invention is unlocked, the unlocking gear 106 and the unlocking motor driving the unlocking gear 106 to rotate can be kept in the release position, and return to the position after the self-priming side door lock is fully opened, thereby improving the user experience.

[0107] In addition, the unlocking gear 106 can be reset by a reset spring. For example, the reset spring can be mounted on the unlocking gear 106, with one leg fixed to the unlocking gear 106 and the other leg fixed to the lock body. At this time, the reset spring can provide a reset force for the unlocking gear 106.

[0108] In the present disclosure, the self-priming side door lock may also include a pawl switch, which is used to detect the position of the pawl, and judge whether the self-priming side door lock is in a locked state or an open state according to the position of the pawl. In addition, the self-priming side door lock may also include a suction start switch, and the controller may start the suction action according to the triggering state of the suction start switch. Specifically, when the suction start switch is triggered, the suction motor starts, so that the self-priming side door lock is locked. At the same time, the self-priming side door lock may also include a half-lock switch and a full-lock switch, etc., so that it is possible to detect whether the lock tongue component is in a half-lock position through the half-lock switch, and detect whether the lock tongue is in a full-lock position through the full-lock switch, etc.

[0109] The self-priming side door lock further comprises a lock buffer block, which is arranged on the lock body and is used to at least partially absorb the energy of the lock. Moreover, a sealing component can be arranged inside the lock body, and the sealing component can be formed by foam.

[0110] The self-priming side door lock may also include a lock core pull rod 107, which can be activated by a key to achieve mechanical insurance and release of the self-priming side door lock. Specifically, the rotation (swing) of the lock core pull rod 107 can drive the above-mentioned central control worm gear 402 to move, thereby further driving the central control transition rod 403 to move, thereby achieving insurance and release of the self-priming side door lock. And after the self-priming side door lock is released, the self-priming side door lock can be unlocked by the outer opening pull rod 105.
