The middle part of the lock buckle limiting piece 401 is rotatably connected to a second rotation positioning shaft 403. The second rotation positioning shaft 403 is provided on the locking plate 5. A flexible driving fit is formed between the lock buckle limiting piece 401 and the locking plate 5 through the lock buckle limiting elastic member 402; one end of the lock buckle limiting piece 401 can engage with and disengage from the lock buckle piece 301, and the other end of the lock buckle limiting piece 401 can be connected to the driving mechanism 2 through a cam transmission mechanism 6. Functions: (1) By including a housing with a lock port provided on the housing, a locking plate provided inside the housing, and a driving mechanism, a lock buckle mechanism, and a lock buckle limiting mechanism provided on the locking plate, and the lock buckle mechanism passes through the lock port horizontally; thus, when it is necessary to protect the battery on an electric vehicle, the battery to be protected can be first placed in a protection cavity (not shown in the figure). Since the opening of the protection cavity has a protection cover (not shown in the figure), the protection cover and the opening can perform locking and unlocking actions through the vehicle lock device and a locking point (not shown in the figure) (that is, the lock buckle mechanism of the vehicle lock device can horizontally cross the lock port and perform locking and unlocking actions with the locking point), so as to realize the locked state and the unlocked state of the protection cover. (2) By the lock buckle mechanism including a lock buckle piece and a lock buckle elastic member, the middle part of the lock buckle piece is rotatably connected to a first rotation positioning shaft, the first rotation positioning shaft is provided on the locking plate, and a flexible driving fit is formed between the lock buckle piece and the locking plate through the lock buckle elastic member, and the lock buckle piece passes through the lock port horizontally; thus, the lock buckle piece of the lock buckle mechanism can horizontally cross the lock port and perform locking and unlocking actions with the locking point (that is, the lock buckle piece can be driven to rotate around the first rotation positioning shaft, and at the same time, the flexible driving of the lock buckle elastic member can be used to realize reset), so as to realize the locked state and the unlocked state of the protection cover.(3) The latch limit mechanism includes a latch limit member and a latch limit elastic member. The middle of the latch limit member is rotatably connected to the second rotation positioning shaft, and the second rotation positioning shaft is arranged on the locking plate. A flexible driving fit is formed between the latch limit member and the locking plate through the latch limit elastic member. One end of the latch limit member can engage with and disengage from the latch. The other end of the latch limit member can be connected to the driving mechanism through the cam transmission mechanism. Thus, the driving mechanism can be used to drive the cam transmission mechanism and the movement of the latch limit member in sequence. At the same time, one end of the latch limit member can engage with and disengage from the latch, and the latch elastic member and the latch limit elastic member are used to realize the reset rotation of the latch and the latch limit member respectively, so as to realize the unlocking and locking actions between the latch and the locking point. From this analysis, through the simple structural cooperation of the driving mechanism, the cam transmission mechanism, the latch mechanism and the latch limit mechanism, the unlocking and locking actions of the vehicle lock device are realized. The vehicle lock has good stability, and the structures of the mechanisms in the whole housing are compact, which reduces the overall volume of the housing and is conducive to concealed installation.

[0029] Specifically, the latch elastic member 302 is a first torsion spring. The latch elastic member 302 is arranged on the first rotation positioning shaft 303. The two ends of the latch elastic member 302 are respectively connected to the latch 301 and the locking plate 5. The latch limit elastic member 402 is a second torsion spring. The latch limit elastic member 402 is arranged on the second rotation positioning shaft 403. The two ends of the latch limit elastic member 402 are respectively connected to the latch limit member 401 and the locking plate 5. Function: Since the latch elastic member 302 is a first torsion spring and the latch limit elastic member 402 is a second torsion spring, the latch 301 and the latch limit member 401 are more stable when being flexibly driven to reset and rotate.

[0030] Specifically, the edge of the latch 301 is provided with a first latch portion 304 and a second latch portion 305 which are distributed in sequence. The first latch portion 304 and the second latch portion 305 cross the lock opening 101. There is a first interval 309 between the first latch portion 304 and the second latch portion 305. The first latch portion 304 and the second latch portion 305 can swing back and forth in the lock opening 101. Function: Through the arrangement of the first latch portion 304, the second latch portion 305 and the first interval 309, the latch 301 can better cross the lock opening outward and perform the locking and unlocking actions with the locking point.

[0031] Specifically, a third locking portion 307 is further provided at the edge of the locking fastener 301, and the third locking portion 307 is disposed on the side of the locking fastener 301 away from the second locking portion 305; first locking limit portions 404 and second locking limit portions 405 are respectively provided at the two side edges of the locking limit member 401, and the first locking limit portion 404 can engage with and disengage from the third locking portion 307, and the cam drive mechanism 6 is located on the side of the second locking limit portion 405 away from the locking fastener 301. Function: During actual operation, for better cooperation, the driving directions of the first torsion spring and the second torsion spring are both clockwise. The vehicle lock device and the locking point are respectively arranged at the opening of the protection cavity and the protection cover, and the locking point is located on the right side of the vehicle lock device. The vehicle lock device and the locking point are locked and unlocked in the up and down direction (not shown in the figure). Thus, by driving the cam drive mechanism to rotate clockwise by the drive mechanism, the cam drive mechanism can press down the second locking limit portion 405 to the right, so that the first locking limit portion 404 rotates counterclockwise and disengages from the third locking portion 307, and at the same time, the third locking portion 307 rotates clockwise to achieve the unlocked state. When it is necessary to return to the locked state, the drive mechanism drives the cam drive mechanism to rotate counterclockwise, and the second locking limit portion 405 is no longer pressed. Under the elastic force of the second torsion spring, the locking limit member 401 rotates clockwise. At the same time, when the protection cover is manually pushed upward to reset, the locking point on the protection cover pushes the locking fastener 301 to rotate counterclockwise until the engagement groove 406 engages with the engagement block 308 again to achieve the locked state, and the forces of all parties reach balance.

[0032] Specifically, a bite slot 406 is provided on one side of the first latch limiting part 404 close to the third latch part 307, and a bite block 308 is provided on one side of the third latch part 307 close to the first latch limiting part 404. The bite slot 406 can be engaged with or disengaged from the bite block 308. A cover plate 8 is fixed to the locking plate 5 by screw locking. The latch mechanism 3 and the latch limiting mechanism 4 are located between the cover plate 8 and the locking plate 5. An activity slot 501 is provided at the edge between the cover plate 8 and the locking plate 5. A toggle rod 407 is provided on one side of the first latch limiting part 404 away from the bite slot 406. A toggle opening 102 is provided on the housing 1. The toggle rod 407 passes through the activity slot 501 and is movably matched with the toggle opening 102. Function: In the locked state, by using the elastic force of the first torsion spring and the second torsion spring, the bite slot 406 can be engaged with the bite block 308, so as to achieve stable force and maintain the locked state. When unlocking is required, the driving mechanism drives the cam transmission mechanism to press down the second latch limiting part 405 to the right, thereby driving the latch limiting member to rotate counterclockwise. At the same time, with the cooperation of the elastic force of the first torsion spring, the bite slot 406 is disengaged from the bite block 308, and the latch 301 rotates clockwise to achieve unlocking. At this time, the protective cover can be pushed down to open. When it is necessary to return to the locked state, the driving mechanism drives the cam transmission mechanism to reset, and the second latch limiting part 405 is no longer pressed. Under the elastic force of the second torsion spring, the latch limiting member 401 rotates clockwise. At the same time, manually push the protective cover to reset upward, and the locking point on the protective cover pushes the latch 301 to rotate counterclockwise until the bite slot 406 is engaged with the bite block 308 again to achieve the locked state, and the forces of all parties reach balance. The setting of the activity slot 501 can limit the rotation amplitude of the toggle rod 407. With the setting of the toggle rod 407, a person can manually drive the swing of the toggle rod 407 through the toggle opening 102, so as to achieve manual unlocking.

[0033] Specifically, a detection part 306 is further provided at the edge of the latch 301. The detection part 306 is arranged on the side of the latch 301 away from the first latch part 304. An in-place detection mechanism 7 is provided on one side of the driving mechanism 2 close to the latch 301. The detection end of the in-place detection mechanism 7 can be connected to or disengaged from the detection part 306. Function: Through the detection of the in-place detection mechanism 7, the position state of the latch 301 at this time can be detected, and a signal can be sent to the driving mechanism, so as to better perform the unlocking action and the locking action.

[0034] Specifically, the cam drive mechanism 6 includes a cam body member 601 and a toggle limit member 602 which are connected to each other. The cam body member 601 is connected to the drive mechanism 2, and the toggle limit member 602 is located on the side of the second latch limit portion 405 away from the latch member 301; there is a second gap 603 between the cam body member 601 and the toggle limit member 602, and the second latch limit portion 405 is located in the second gap 603 between the cam body member 601 and the toggle limit member 602, so that the toggle limit member 602 can be in contact with the second latch limit portion 405. Function: Driven by the drive mechanism, the cam body member 601 drives the toggle limit member 602, and then the toggle limit member 602 presses the second latch limit portion 405 downward to the right, and then drives the latch limit member to rotate counterclockwise.

[0035] Specifically, the drive mechanism 2 includes a gearbox 201. Inside the gearbox 201, there are a second main shaft member 203, a gear assembly 204, and a motor 205. The motor 205 drives the second main shaft member 203 to rotate through the gear assembly 204. The end of the second main shaft member 203 passes outward through the gearbox 201 and is connected to the cam body member 601. Function: When the motor 205 drives the second main shaft member 203 to rotate through the gear assembly 204, the second main shaft member 203 drives the cam body member 601 to rotate.

[0036] Specifically, a first main shaft member 202 is also provided inside the gearbox 201. The first main shaft member 202 is arranged in parallel with the second main shaft member 203. The gear assembly 204 includes a first clutch tooth member 2041 and a second clutch tooth member 2042. The first clutch tooth member 2041 and the second clutch tooth member 2042 are respectively sleeved on the first main shaft member 202 and the second main shaft member 203, and the first clutch tooth member 2041 meshes with the second clutch tooth member 2042. Function: When the motor 205 drives the first clutch tooth member 2041, the second clutch tooth member 2042, and the second main shaft member 203 to rotate in sequence, the second main shaft member 203 drives the cam body member 601 to rotate.

[0037] Specifically, a clutch elastic member 2043 is also sleeved on the first main shaft member 202. The clutch elastic member 2043 elastically abuts against the end face of the first clutch tooth member 2041. The clutch elastic member 2043 acts on the first clutch tooth member 2041 so that the first clutch tooth member 2041 can mesh with the second clutch tooth member 2042. Function: Through the arrangement of the clutch elastic member 2043, the first clutch tooth member 2041 and the second clutch tooth member 2042 are better meshed together.

[0038] In summary, the beneficial effects of this design are as follows: Through the simple structural cooperation of the driving mechanism, cam transmission mechanism, lock mechanism, and lock limit mechanism, the locking and unlocking actions of the vehicle lock device are realized. The vehicle lock has good stability, and the driving mechanism, lock mechanism, and lock limit mechanism are installed and arranged around the cam transmission mechanism within the housing. The structures of various mechanisms within the entire housing are compact, which reduces the overall volume of the housing and is conducive to concealed installation.
