[0029] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention, and the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] In each embodiment, for the convenience of description and not to limit the present invention, the term "connection" used in the patent application specification and claims of the present invention is not limited to physical or mechanical connection, but may include electrical connection, whether direct or indirect. "Up", "down", "below", "left", "right", etc. are only used to indicate relative position relationship. When the absolute position of the described object changes, the relative position relationship also changes accordingly.

[0033] like Figures 1 to 10As shown, a vehicle battery lock locking and unlocking mechanism includes a housing 1, a locking and unlocking assembly 2 installed in the housing 1, and a driving assembly 3 driving the locking and unlocking assembly 2 to operate. The locking and unlocking assembly 2 includes a hollow shaft body 4 and a locking and unlocking head 5 floatingly installed in the hollow shaft body 4. The present invention has a simple structure, occupies a small space, provides more precise control and feedback, and improves the success rate of vehicle battery replacement. The driving assembly 3 transmits the power torque to the locking and unlocking assembly 2, and the locking and unlocking assembly 2 can be assembled with different types of locking and unlocking heads 5, thereby realizing the unlocking of battery packs and vehicles assembled with different types of battery locks.

[0034] The locking and unlocking assembly 2 also includes a floating pin 6 sleeved in the hollow shaft body 4 and a reset spring 7 sleeved in the inner cavity of the floating pin 6 and the inner cavity of the hollow shaft body 4 in sequence. A locking pin 8 is provided between the floating pin 6 and the locking and unlocking head 5. The reset spring 7 provides a reset power for the floating pin 6. The locking and unlocking head 5 is hingedly fixed to the floating pin 6 by the locking pin 8, and can be deflected around the locking pin 8 on the floating pin 6. Due to the limitation of the spatial structure of the floating pin 6, it can only be deflected at a certain angle to adapt to the situation that the battery pack lock may be tilted. Because the locking and unlocking head 5 can be made into a detachable structure, when different battery locks need to be unlocked, the locking and unlocking head 5 can be replaced accordingly, such as replacing the Dongfeng straight unlocking head, replacing the SAIC hexagonal unlocking head, and replacing the Weilai plum blossom polygonal unlocking head, etc., so that the locking and unlocking head 5 can be replaced without changing the unlocking base.

[0035] The upper end cover of the hollow shaft body 4 is provided with a stopper 9 which limits the floating pin 6 .

[0036] The upper and lower outer walls of the hollow shaft body 4 are respectively provided with bosses, which are clamped in the housing 1. The clamping part of the boss is provided with a bearing 10 to facilitate the rotation of the hollow shaft body 4.

[0037] The upper and lower ends of the housing 1 are respectively provided with an upper cover plate 11 and a lower cover plate 12. Of course, the upper and lower parts of the hollow shaft body 4 can be clamped on the upper cover plate 11 and the lower cover plate 12 respectively.

[0038] A detection component 13 is provided at the bottom of the housing 1. The unlocking and locking states of the battery lock are determined by identifying the rotational position of the locking and unlocking head 5. As a specific embodiment, the detection component 13 can be implemented using a proximity sensor switch to detect the mark on the hollow shaft body 4 in the locking and unlocking component 2, such as a notch structure, and set up multi-point detection. When there is no signal from the detection device at a certain point, the rotational position and angle of the hollow shaft body 4 can be determined at the position of this detection device. In this way, the position and state of the hollow shaft body 4 in the locking and unlocking component 2 can be accurately identified, and then the unlocking and locking states of the battery pack lock can be determined.

[0039] The driving assembly 3 includes a motor 14 , a reducer 15 drivingly connected to the motor 14 , and a transmission assembly 16 drivingly connected to the reducer 15 and the hollow shaft 4 .

[0040] The transmission assembly 16 includes a spur gear 17 disposed at the output end of the reducer 15 and a bevel gear 18 meshing with the spur gear 17, and the bevel gear 18 is fixedly connected to the hollow shaft body 4. The spur gear 17 is fixedly connected to the output shaft of the reducer 15 to transmit torque, and the bevel gear 18 changes the torque direction and transmits torque power, so as to maximize the use of the space of the locking and unlocking assembly 2, making the overall structure more compact, and due to the characteristics of the gear meshing transmission, the entire locking and unlocking process is also stable, and the impact vibration noise is small. The output end of the bevel gear 18 is fixedly connected to the hollow shaft body 4 of the locking and unlocking assembly 2 to transmit this stable power; due to the use of a gear meshing structure, sufficient lubrication is required, and oil seals 19 can be set at the upper and lower ends of the housing 1 to achieve the effect of sealing oil, preventing dust and reducing noise.

[0041] A clamping block 20 is disposed on the outer wall of the hollow shaft body 4 , and a clamping groove 21 matched with the clamping block 20 is formed on the bevel gear 18 .

[0042] Working principle:

[0043] There is a floating pin 6 sliding inside the hollow shaft body 4, but due to its structural blocking, relative rotation does not occur. It can be achieved by using a key connection to slide inside the hollow shaft body 4, and a blocking cover 9 is used to limit the sliding of the floating pin 6 within a certain range, and the floating effect and the unlocking position are guaranteed by the floating reset force generated by the reset spring 7. The locking and unlocking head 5 is hingedly connected to the floating pin 6 through the blocking pin 8, and it has a deflection ability of a certain angle to adapt to the possible tilt of the battery lock; when unlocking, the battery lock position is accurately positioned by the up and down floating and axial deflection of the locking and unlocking head 5, and the hollow shaft body 4 is driven to rotate via the transmission assembly 16, so that the floating pin 6 and the locking and unlocking head 5 are rotated to unlock.
