[0014] Furthermore, the gap between the inner cover and the inner shell is provided with a sealing structure.
[0015] Furthermore, the power mechanism also includes a control board, which is located inside the inner shell and connected to the motor.
[0016] Furthermore, when the lock is in the anti-theft position, the length direction of the cam is parallel to the movement direction of the lock.

[0018] Furthermore, the lock includes a latch seat and a latch located at the front end of the latch seat, and the cam groove is located at the bottom of the latch seat.
[0019] Furthermore, it also includes a first reset member, the two ends of which respectively abut against the locking tongue seat and the inside of the outer shell.
[0020] Furthermore, the top of the cam is provided with a protrusion at the pivot, and the lock is provided with a limiting groove that extends from the top surface of the lock to the cam groove. The limiting groove accommodates the protrusion and its length direction is parallel to the length direction of the lock tongue seat.
[0021] A battery compartment lock includes the aforementioned vehicle lock, and a positioning detection device for detecting whether the battery is installed in place.

[0055] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0056] A type of vehicle lock, see Figures 1 to 12 The system includes a housing 1, a locking element 2 inside the housing 1, and a drive mechanism for extending and retracting the locking element 2. The housing 1 has a lock hole 10 that allows the front end of the locking element 2 to pass through. The drive mechanism includes a cam 3 and a power mechanism that drives the cam 3 to rotate eccentrically. The locking element 2 has a cam groove 20 that accommodates the cam 3. When the locking element 2 is in the locked position and is subjected to an external force opposite to the locking direction, the cam 3 is pushed by the cam groove 20 to rotate in the unlocking direction. When unlocking, the power mechanism drives the cam 3 to rotate eccentrically, causing the cam 3 to push the cam groove 20 to retract the locking element 2. When locking, the cam 3 pushes the cam groove 20 to extend the locking element 2. At this time, the locked position of the locking element 2 causes it to be subjected to an external force opposite to the locking direction. The cam 3 is pushed by the cam groove 20 to rotate in the unlocking direction, forming a force-relieving mechanism. This avoids damage to the drive mechanism caused by external forces, greatly reducing the repair and maintenance costs caused by human-caused damage. There are fewer broken cars on the road, resulting in a better user experience. Preferably, it also includes an outer cover that covers the side opening of the housing 1 to facilitate component installation and protection.
[0057] When the locking element 2 is in the locked position, the length direction of the cam 3 is inclined relative to the direction of movement of the locking element 2. This ensures that the cam 3 can rotate to relieve force when the locking element 2 is pushed.
[0058] The power mechanism includes a motor 4 and a transmission mechanism 40 that connects the motor 4 to the cam 3. Such a power mechanism is simple and reliable.
[0059] The transmission mechanism 40 includes a motor gear 41 on the motor shaft 4, a driven wheel 42 meshing with the motor gear 41, and a main shaft 43 fixed coaxially with the driven wheel 42 and the cam 3. Such a transmission mechanism 40 is simple and reliable.
[0060] It also includes an inner shell 5 and an inner cover 50. The transmission mechanism 40 is located inside the inner shell 5, and the main shaft 43 passes through the main shaft hole 51 on the inner shell 5 and is fixedly connected to the cam 3. This provides waterproof and dustproof protection for the transmission mechanism 40, such as the motor, making it more durable and extending its lifespan. The inner shell 5 separates the transmission mechanism 40 from the locking element 2, ensuring both waterproof and dustproof protection for the transmission mechanism 40 and providing space for the locking element 2 to move smoothly.
[0061] The housing 1 also includes a position detection plate 6 for detecting the position of the cam 3, which is electrically connected to the motor 4. This allows for feedback based on the running position of the cam 3, detection of the locked state, and limitation of the cam 3 to a specified position.
[0062] The cam 3 has a magnet 30 on its protrusion, and the position detection plate 6 is a Hall sensor. This detection structure is simple and reliable.
[0063] The inner shell 5 also includes a motor slot 52 and a fixing member 53. The motor 4 is located in the motor slot 52 and is separated from the main shaft 43. The fixing member 53 is installed on the end face of the motor slot 52 and covers the motor 4. This allows for precise installation of the motor 4 and the main shaft 43, and provides secondary protection for the motor 4, making it more durable.
[0064] The gap between the inner cover 50 and the inner shell 5 is provided with a sealing structure. This can further improve the dustproof and waterproof effect.
[0065] The power mechanism also includes a control board 7, which is located inside the inner shell 5 and connected to the motor 4. The control board 7 can control the electronic components and is further protected by the inner shell. Preferably, the data cable extending outward from the control board 7 has a sealing structure at the wire hole where it passes through the outer shell 1 and the inner shell 5.
[0066] When the lock 2 is in the anti-theft position, the length direction of the cam 3 is parallel to the movement direction of the lock 2. When the lock 2 is pushed, the cam 3 will not rotate, thus preventing theft of the vehicle and / or battery.
[0067] A sealing ring 54 is provided at the spindle hole 51 to seal the gap between the spindle 43 and the spindle hole 51. The sealing ring can prevent water, dust, oil, sand and gravel from entering the transmission mechanism 40, thereby improving the operating environment and service life.
[0068] The lock component 2 includes a latch seat 21 and a latch 22 located at the front end of the latch seat 21, with a cam groove 20 located at the bottom of the latch seat 21. This allows for the differentiation of materials for use and separate maintenance as needed. Preferably, the lock component 2 and the latch seat 21 are fixedly connected by screws. Preferably, the latch seat 21 and the inner wall of the outer casing 1 are slidably engaged by a slide rail.
[0069] It also includes a first reset member 23, with its two ends abutting against the latch seat 21 and the interior of the outer casing 1, respectively. The first reset member 23 can provide a reset force to the lock member 2. Preferably, the latch seat 21 and the first reset member 23 are provided with a positioning groove at the abutment point to accommodate one end of the first reset member 23, so as to prevent the first reset member 23 from shifting.
[0070] The cam 3 has a protrusion 31 at its top located at the pivot point. The locking member 2 has a limiting groove 24 extending from the top surface of the locking member 2 to the cam groove 20. The limiting groove 24 accommodates the protrusion 31 and its length direction is parallel to the length direction of the latch seat 21. The limiting groove 24 can limit the movement range of the latch seat 21, avoid surface friction between the latch seat 21 and the inner wall of the outer casing 1, and make the movement of the latch seat 21 smoother.
[0071] Example 1 of battery compartment lock:
[0072] A battery compartment lock, see Figure 13 and Figure 14 This includes the aforementioned vehicle lock, and a positioning detection device 8 for detecting whether the battery is properly installed. The positioning detection device 8 includes a travel housing 80, a trigger head 81 inside the travel housing 80, a second reset member 82, and a micro switch 83. The two ends of the second reset member 82 respectively abut against the trigger head 81 and the micro switch 83. The trigger head 81 extends outside the travel housing 80, and the micro switch 83 is electrically connected to the drive mechanism. When the battery is installed, pushing the trigger head 81 presses the micro switch 83, sending feedback to the drive mechanism that the battery is in place. This allows the drive mechanism to engage the lock 2 to lock the battery or perform anti-theft operations. Preferably, the data cable between the micro switch 83 and the drive mechanism has a sealing structure at the wire hole through the outer shell 1 and inner shell 5.
[0073] Example 2 of the battery compartment lock:
[0074] See Figures 15 to 17 Unlike Embodiment 1, this embodiment also includes a battery holder 9 and a movable block 91. The battery holder 9 has a clearance hole 90 that allows the locking member 2 to pass through, and a movable groove 92 that accommodates the movable block 91. One end of the movable block 91 extends outside the battery holder 9, and the other end abuts against the trigger head 81. The front end of the locking member 2 corresponds to the clearance hole 90. The battery holder 9 provides an installation position for the battery, and the movable block 91 connects the detection and transmission between the battery and the positioning detection device 8.
[0075] The battery holder 9 has a locking groove 93 on its back, and the front end of the housing 1 is embedded in the locking groove 93. The battery holder 9 provides an installation position for the vehicle lock, making it easy to stably align the lock hole 10 with the clearance hole 90.
[0076] The battery holder 9 is provided with a detection groove 94, and the positioning detection device 8 is embedded in the detection groove 94. The movable groove 92 is connected to the detection groove 94. The battery holder 9 provides an installation position for the positioning detection device 8 and realizes a stable connection between the movable block 91 and the positioning detection device 8 for detection and transfer.
[0077] The movable block 91 and the movable slot 92 are connected to each other by a third reset member 95. This ensures that the movable block 91 always abuts against the battery, resulting in accurate detection.
