The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and cannot be understood as limiting the present disclosure.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, unless otherwise specified, "multiple" means two or more.

[0036] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0037] To facilitate understanding of the embodiments of the present disclosure, the vehicle door lock technology in the related art is first further described.

[0038] The door locks of motor vehicles usually have two functions: electric unlocking and manual unlocking. When the lock is in the locked position, electric unlocking and manual unlocking are inoperable. When the lock is in the unlocked position, electric unlocking and manual unlocking are operable. When the electric unlocking fails, it is necessary to ensure that the manual unlocking can operate normally. For example, when the electric opening arm loses the reset power due to a motor failure in the electric unlocking mechanism, the door lock will remain in the open state and cannot be closed. Only when the lock is turned back to the locked position can the door lock be reset to the closed state. When opening the door, the lock is turned to the unlocked position, but at this time the linkage connected to the electric opening arm that cannot be reset will interfere with the activity of the unlocking clutch, making it impossible to reach the unlocking position, and manual unlocking is also impossible. In the related art, a clearing area is set for the linkage so that the unlocking clutch can reach the unlocking position, thereby ensuring that the door can be manually unlocked and opened.

[0039] When the electric unlocking device controls the door unlocking, if the locking device is quickly switched from the unlocking position to the locking position and then switched back to the unlocking position, the unlocking clutch will enter the avoidance area of ​​the linkage part, and the rectangular unlocking clutch will cause the linkage part to get stuck, and the electric opening arm cannot be reset, causing the electric unlocking device to fail to control the door unlocking.

[0040] Reference below Figure 1-5 The embodiments according to the present disclosure are described in detail. Figure 1 The present invention discloses a door operating mechanism, in which a lock seat 10 can move along a preset direction to release the door. The preset direction can be a direction of rotational movement or a direction of linear movement. The following only takes rotational movement as an example for illustrative description. Figure 1 The position of the middle lock head 13 is the door lock locking position. When the lock base 10 rotates counterclockwise with the rotating shaft 1, the door lock is opened to release the door.

[0041] like Figure 1 and Figure 2 The electric opening part 20 is used to electrically drive the lock seat 10 to release the door. The electric opening part 20 includes an electric opening arm 21 and a linkage member 22. The electric opening arm 21 is rotatably connected to the lock seat 10 and rotates around the rotation axis 1. The linkage member 22 is rotatably connected to the electric opening arm 21 and rotates around the rotation pin 24; the linkage member 22 includes a linkage member body 221 and a bending portion 222, and the bending portion 222 is connected to the linkage member body 221 to form an air avoidance area S;

[0042] The unlocking clutch 30 is connected to the lock seat 10; the unlocking clutch 30 includes a force-bearing surface 311 and a guide surface 312;

[0043] like Figure 1 When the unlocking clutch 30 is located in the clearing area S and the electric opening arm 21 moves away from the unlocking clutch 30, after the bent portion 222 abuts against the guide surface 312, the linkage member 22 moves relative to the electric opening arm 21 in the first direction (for example, Figure 1 When the bent portion 222 is disengaged from the unlocking clutch 30, the linkage member 22 rotates in the second direction, that is, the counterclockwise direction, to the position as shown in FIG. Figure 3 The preset angle enables the electric opening arm 21 to move toward the unlocking clutch 30 again, and the bent portion 222 can contact the force-bearing surface 311 to drive the lock seat 10 to move along the preset direction to release the door. The operating structures of the left and right doors of the vehicle are usually mirror-symmetrical, and the above-mentioned action relationship is satisfied as long as the second direction is opposite to the first direction.

[0044] In the related technical solution, when the electric unlocking device controls the door unlocking, the locker is quickly switched from the unlocking position to the locking position and then switched back to the unlocking position, and the unlocking clutch will enter the air-avoiding area, and the bent part is blocked by the rectangular unlocking clutch, so that the electric opening arm cannot be automatically reset, resulting in a fault that cannot be electrically unlocked. After this fault occurs, the user needs to switch the locker from the unlocking position to the locking position again, and then to the unlocking position to restore the electric unlocking function, but few users know or remember this operation, which causes trouble and trouble to the user. Compared with this related technology, the unlocking clutch in this technical solution is processed with a guide surface. When the unlocking clutch enters the air-avoiding area, the linkage part can rotate under the guidance of the guide surface. As the electric opening arm moves away from the unlocking clutch, the linkage part can be separated from the unlocking clutch. Therefore, the linkage part will not be blocked by the unlocking clutch and stuck, so that the electric opening arm can be automatically reset, avoiding the fault of the above-mentioned related technology. The solution is ingenious and easy to implement, and will not increase the cost and user's operation difficulty.

[0045] In such Figure 1 In one embodiment shown, the guide surface 312 can be an inclined surface, which is easy to process, and can also be composed of curved surfaces such as arc surfaces. The guide surface 312 and the force-bearing surface 311 can be smoothly connected to avoid stress concentration and damage to parts, and also make the bending portion 222 easier to move under the guidance of the guide surface 312. The bending portion 222 can include a smooth portion. When the bending portion 222 abuts against the guide surface 312, the smooth portion abuts against the guide surface 312. The use of the smooth portion structure makes it easier for the bending portion 222 to slide on the guide surface 312.

[0046] like Figure 2 The linkage 22 may further include a torsion spring 23, one end of which is connected to the linkage body 221, and the other end of which is connected to the electric opening arm 21, so that when the bending portion 222 is disengaged from the unlocking clutch 30, the linkage 22 can rotate to a preset angle in the second direction. The torsion spring has a simple structure and occupies a small space. In other embodiments, other elastic elements can be used to realize that when the bending portion 222 is disengaged from the unlocking clutch 30, the linkage 22 can rotate to a preset angle in the second direction.

[0047] like Figure 2 As shown, the door operating mechanism may further include a rotation limiting structure for limiting the rotation angle of the linkage member 22 in the first direction and / or the second direction. Figure 2The first direction is the clockwise direction, and the second direction is the counterclockwise direction. The rotation limiting structure may include a limiting plate 223 and a limiting groove 211, wherein the limiting plate 223 is fixedly connected to the linkage member 22, and the limiting groove 211 is formed in the electric opening arm 21; when the linkage member 22 rotates, the limiting plate 223 moves in the limiting groove 211; the limiting groove 211 includes a first blocking surface 211a and a second blocking surface 211b; when one side of the limiting plate 223 abuts against the first blocking surface 211a, the rotation angle of the linkage member 22 in the first direction is limited; when the other side of the limiting plate 223 abuts against the second blocking surface 211b, the rotation angle of the linkage member 22 in the second direction is limited.

[0048] like Figure 3 and Figure 4 The lock base 10 may be provided with a sliding hole 11, one end of the sliding hole 11 is an unlocking position P1, and the other end of the sliding hole 11 is a locking position P2; the unlocking clutch 30 can slide in the sliding hole 11, and when the unlocking clutch 30 is located at the unlocking position P1, the electric opening part 20 can be used to electrically drive the lock base 10 to release the door. When installing the unlocking clutch 30, the unlocking clutch 30 enters the sliding hole 11 with a smaller aperture through the mounting hole 12 with a larger aperture.

[0049] like Figure 5 The unlocking clutch 30 may also include a contact member 31 and a sliding member 32. A force-bearing surface 311 and a guide surface 312 are formed on the contact member 31. The contact member 31 may be a columnar body such as a triangular prism or a quadrangular prism. The specific shape thereof is not limited in the present disclosure. The contact member 31 is connected to the sliding member 32, and the sliding member 32 can slide in the sliding hole 11. The sliding member 32 is a cylinder, and the diameter of the sliding member 32 is greater than the width of the sliding hole 11; two sliding grooves 331 may be provided on the side of the sliding member 32, and the two sliding grooves 331 constitute two parallel flat surfaces; the two parallel flat surfaces cooperate with the sliding hole 11 so that the sliding member 32 can slide in the sliding hole 11. By adopting the above structure, the unlocking clutch 30 can maintain the position of the contact member 31 without deflection when sliding, ensuring the relative position relationship when the bending portion 222 abuts against the force-bearing surface 311 and the guide surface 312; in addition, grease can be contained in the sliding groove 331, so that the unlocking clutch 30 can slide more smoothly and reduce wear.

[0050] The unlocking clutch 30 may further include a conductive member 34, which is connected to the sliding member 32 and is located on the opposite side of the sliding member 32 as the contact member 31. The conductive member 34 is suitable for connecting with an action mechanism to control the unlocking clutch 30 to slide in the sliding hole 11. The action mechanism may be a locker commonly used in the art, or other mechanisms, which are not limited in the present disclosure.

[0051] In a second aspect of the embodiment of the present disclosure, a vehicle door is provided, including a vehicle door operating mechanism described in the first aspect of the above embodiment, so it has all the beneficial effects of the lock assembly mechanism described in the above embodiment, and no further elaboration is made here. The vehicle door can be horizontally movable, flat-opening, reverse-opening, upward-lifting or folding, etc., and the present disclosure does not limit it.
