The locking fastener is in contact with the lock tongue. The locking buckle torsion spring is sleeved on the locking buckle shaft, and one end of the locking buckle torsion spring is in contact with the locking fastener, and the other end of the locking buckle torsion spring is in contact with the mounting body.

[0008] In one embodiment, a first interference block and a second interference block are spaced apart on the lock tongue member along the circumference of the lock tongue member, and a interference recess is provided on the locking fastener for engaging and interfering with the first interference block and the second interference block. When the first interference block interferes with the interference recess, the lock tongue member and the locking fastener are in a semi-locked state, and when the second interference block interferes with the interference groove, the lock tongue member and the locking fastener are in a fully locked state.

[0009] In one embodiment, the adjustment actuator includes an actuator and a transmission assembly, the actuator is used to cooperate with one end of the connecting rod assembly, one end of the transmission assembly is connected to the locking fastener, and the other end of the transmission assembly is movably connected to the connecting rod assembly, and the adjustment member is installed on the transmission assembly.

[0010] In one embodiment, the connecting rod assembly includes a first connecting rod, a second connecting rod, a first return torsion spring, a second return torsion spring, a first rotating shaft and a second rotating shaft, the first rotating shaft is installed on the mounting body, the first connecting rod is rotatably engaged with the mounting body through the first rotating shaft, the first connecting rod is used to interfere with the actuator, the second connecting rod is rotatably engaged with the first connecting rod through the second rotating shaft, and the second connecting rod is used to interfere with the lock tongue member, the first return torsion spring and the second return torsion spring are sequentially mounted on the first rotating shaft along the height direction of the first rotating shaft, the first return torsion spring elastically interferes with the first connecting rod, and the second return torsion spring elastically interferes with the second connecting rod.

[0026] Combine Figures 1 to 3 As shown, in one embodiment, an electric locking device includes: a mounting body 100, an adjustment actuator, a lock tongue assembly 300, a locking buckle assembly 400 and a connecting rod assembly 500, wherein the lock tongue assembly 300 and the locking buckle assembly 400 are movably mounted on the mounting body 100, the lock tongue assembly 300 and the locking buckle assembly 400 are locked in abutment with each other, the adjustment actuator is used to drive the lock tongue assembly 300 and the locking buckle assembly 400 to separate from each other, the connecting rod assembly 500 is connected to the adjustment actuator, and the adjustment actuator can be driven to move through the connecting rod assembly 500.

[0027] When using the above-mentioned electric locking device, first, depending on the actual usage, the above-mentioned electric locking device can be used to lock the tailgate of an automobile. When the electric locking device is in the unlocked state, the adjustment actuator drives the connecting rod assembly 500 to move. At the same time, the movement of the connecting rod assembly 500 can drive the lock tongue assembly 300 to move relative to the locking buckle assembly 400 accordingly, thereby achieving mutual separation of the lock tongue assembly 300 and the locking buckle assembly 400. Furthermore, when the adjustment actuator fails, the adjustment actuator is unable to move the connecting rod assembly 500 accordingly, that is, the connecting rod assembly 500 cannot drive the lock tongue assembly 300 to move relative to the locking buckle assembly 400 accordingly. In this case, the operator can use the adjustment member 212 provided on the adjustment actuator to re-move the adjustment actuator, so that the adjustment actuator can use the connecting rod assembly 500 to separate the lock tongue assembly 300 from the locking buckle assembly 400, that is, completely unlock the electric locking device in the event of a failure.

[0028] Combine Figure 2 and Figure 3 As shown, in one embodiment, the lock tongue assembly 300 includes a lock tongue shaft 310, a lock tongue member 320, and a lock tongue torsion spring 330. The lock tongue shaft 310 is mounted on the mounting body 100. The lock tongue member 320 rotates with the mounting body 100 via the lock tongue shaft 310. The lock tongue member 320 is used to engage with the locking buckle assembly 400. The lock tongue torsion spring 330 is sleeved on the lock tongue shaft 310, with one end of the lock tongue torsion spring 330 engaging with the lock tongue member 320 and the other end of the lock tongue torsion spring 330 engaging with the mounting body 100. Specifically, the lock tongue member 320 is a lock tongue plate or a lock tongue piece. The lock tongue member 320 can be reset and rotated on the lock tongue shaft 310 via the lock tongue torsion spring 330. For example, when the electric locking device is in the locked state, the lock tongue member 320 can be reset and resisted under the elastic force of the lock tongue torsion spring 330, thereby preventing the lock tongue member 320 from moving in the locked state. Furthermore, a protrusion can be added to the lock tongue member 320, and a recess can be added to the lock buckle assembly 400 to correspond to the protrusion. When the lock tongue member 320 and the lock buckle assembly 400 are locked together, the protrusion will extend into the recess, thereby further restricting the lock tongue member 320 and / or the lock buckle assembly 400 from moving in the unlocking direction in the locked state, effectively ensuring the locking effect of the electric locking device.

[0029] Combine Figure 2 and Figure 3As shown, in one embodiment, the locking buckle assembly 400 includes a locking buckle shaft 410, a locking buckle 420, and a locking buckle torsion spring 430. The locking buckle shaft 410 is mounted on the mounting body 100. The locking buckle 420 rotates with the mounting body 100 via the locking buckle shaft 410. The locking buckle 420 abuts against the lock tongue 320. The locking buckle torsion spring 430 is sleeved on the locking buckle shaft 410, with one end of the locking buckle torsion spring 430 abutting against the locking buckle 420 and the other end of the locking buckle torsion spring 430 abutting against the mounting body 100. Specifically, the locking buckle 420 is a locking buckle plate or a locking buckle sheet. The locking fastener 420 can be reset and rotated on the locking fastener shaft 410 by the locking fastener torsion spring 430. For example, when the electric locking device is in the locked state, the locking fastener 420 can be reset and resisted under the elastic force of the locking fastener torsion spring 430, thereby preventing the locking fastener 420 from moving in the locked state. Furthermore, a protrusion can be added to the locking fastener 420, and a recess can be added to the lock tongue member 320 to correspond to the protrusion. When the locking fastener 420 and the lock tongue member 320 are locked together, the protrusion will extend into the recess, thereby further restricting the locking fastener 420 and / or the lock tongue member 320 from moving in the unlocking direction in the locked state, effectively ensuring the locking effect of the electric locking device.

[0030] Combine Figure 2 and Figure 3As shown, in one embodiment, a first interference block 321 and a second interference block 322 are spaced apart on the lock tongue member 320 along the circumference of the lock tongue member 320, and the locking fastener 420 is provided with an interference recess for engaging with the first interference block 321 and the second interference block 322. When the first interference block 321 interferes with the interference recess, the lock tongue member 320 and the locking fastener 420 are in a semi-locked state, and when the second interference block 322 interferes with the interference groove, the lock tongue member 320 and the locking fastener 420 are in a fully locked state. The adjustment actuator includes an actuator and a transmission assembly 210. The transmission assembly 210 is movably mounted in the mounting body 100. The actuator is used to drive the transmission assembly 210 to move, and one end of the transmission assembly 210 is used to interfere with the lock tongue member 320. Specifically, when the electric locking device is locked, the actuator receives the corresponding lock execution command, and the lock tongue assembly 300 is first subjected to an external force. Specifically, the lock tongue member 320 rotates under the external force, causing the first interference block 321 to intersect with the interference recess on the locking latch 420, placing the electric locking device in a semi-locked state. The actuator then operates to drive the transmission assembly 210 to move. When the transmission assembly 210 moves to a certain position, it intersects with the lock tongue member 320. Driven by the transmission assembly 210, the lock tongue member 320 rotates further, disengaging the first interference block 321 from the interference recess. At this point, the second interference block 322 intersects with the interference recess. This effectively ensures the electric locking device reaches a fully locked state. Furthermore, the above-described electric locking device utilizes the actuator to first drive the transmission assembly 210, and then intersects the transmission assembly 210 with the lock tongue member 320, thereby effectively ensuring the freedom of movement of the electric locking device.

[0031] Combine Figure 2 and Figure 3As shown, in one embodiment, the connecting rod assembly 500 includes a first connecting rod 510, a second connecting rod 520, a first return torsion spring 530, a second return torsion spring 540, a first rotating shaft 550 and a second rotating shaft 560, the first rotating shaft 550 is installed on the mounting body 100, the first connecting rod 510 is rotatably engaged with the mounting body 100 through the first rotating shaft 550, the first connecting rod 510 is used to conflict with the actuator, the second connecting rod 520 is rotatably engaged with the first connecting rod 510 through the second rotating shaft 560, and the second connecting rod 520 is used to conflict with the lock tongue member 320, the first return torsion spring 530 and the second return torsion spring 540 are sequentially sleeved on the first rotating shaft 550 along the height direction of the first rotating shaft 550, the first return torsion spring 530 elastically conflicts with the first connecting rod 510, and the second return torsion spring 540 elastically conflicts with the second connecting rod 520. Specifically, when the electric locking device is locked, the actuator receives the corresponding lock execution command, and the lock tongue assembly 300 is first subjected to an external force, that is, the lock tongue member 320 rotates under the external force, causing the first interference block 321 to interfere with the interference recess on the locking buckle 420, placing the electric locking device in a semi-locked state. Then, the actuator operates and drives the first connecting rod 510 to move, causing the first connecting rod 510 to rotate relative to the first rotating shaft 550. The first connecting rod 510 also drives the second connecting rod 520 to move, and the second connecting rod 520 rotates relative to the second rotating shaft 560. After the second connecting rod 520 moves, it interferes with the lock tongue member 320. Driven by the second connecting rod 520, the lock tongue member 320 further rotates, and the first interference block 321 disengages from the interference recess. At this time, the second interference block 322 interferes with the interference recess. The electric locking device is now fully locked. Furthermore, the electric locking device effectively ensures the freedom of movement of the electric locking device by cooperating with the first connecting rod 510 and the second connecting rod 520, and then engaging the transmission assembly 210 with the lock tongue member 320. Furthermore, after the electric locking device is locked, the first connecting rod 510 can be reset to a preset position by the first return torsion spring 530, and the second connecting rod 520 can be reset to a preset position by the second return torsion spring 540.

[0032] Combine Figure 2 and Figure 3As shown, in one embodiment, the transmission assembly 210 includes a transmission link 211, one end of which is movably connected to the second link 520, the other end of which is connected to the locking fastener 420, and the adjusting member 212 is mounted on the transmission link 211. Specifically, when the second link 520 moves and contacts the locking bolt 320, the second link 520 only changes angle with the transmission link 211. That is, the second link 520 does not drive the locking fastener 420 to rotate accordingly through the transmission link 211, thereby ensuring the locking effect of the electric locking device. In addition, the adjusting member 212 is a rod or a block. When the electric locking device needs to be unlocked, the actuator is activated, which contacts the adjusting member 212 and drives the transmission link 211 to move. The transmission link 211 then drives the locking fastener 420 to rotate, achieving the separation of the locking bolt 320 from the locking fastener 420. When the actuator fails, the staff can directly move the adjustment member 212 to enable the transmission connecting rod 211 to drive the locking fastener 420 to rotate.

[0033] Combine Figures 1 to 3 As shown, in one embodiment, the mounting body 100 includes a mounting cover 110 and a mounting housing 120. The adjustment actuator, the locking tongue assembly 300, the locking buckle assembly 400, and the connecting rod assembly 500 are all rotatably mounted within the mounting housing 120, and the mounting cover 110 is detachably fastened to the mounting housing 120. Specifically, the mounting cover 110 and the mounting housing 120 effectively encapsulate the adjustment actuator, the locking tongue assembly 300, the locking buckle assembly 400, and the connecting rod assembly 500, thereby preventing damage to the adjustment actuator, the locking tongue assembly 300, the locking buckle assembly 400, and the connecting rod assembly 500 from external factors. Furthermore, an adjustment opening for the adjustment member 212 to extend out is provided on the surface of the mounting cover 110, so that personnel can adjust the adjustment member 212 in special circumstances.

[0034] Combine Figure 2 and Figure 3 As shown, in one embodiment, the connecting rod assembly 500 further includes an interfering protrusion 570, which is mounted on the first connecting rod 510. The actuator drives the first connecting rod 510 to move via the interfering protrusion 570. Specifically, the interfering protrusion 570 can be an interfering bump or an interfering column, which can facilitate contact between the actuator and the transmission assembly 210.

[0035] In one embodiment, a car includes the electric locking device described in any one of the above embodiments, and also includes a car body, on which a car tailgate and a locking connector are provided, and the car tailgate is locked and fixed by the electric locking device and the locking connector.

[0036] When the tailgate of the aforementioned vehicle is locked to the vehicle body during use, the electric locking device and the locking connector (which may be a lock hook or a locking buckle) are locked and secured. The electric locking device can sense the accumulation of snow on the tailgate and adjust the locking mechanism accordingly. This means that the electric locking device can effectively overcome the effect of accumulated snow on the tailgate, ensuring that the tailgate can be effectively unlocked.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
