One end of the first elastic piece is connected with the lock pin, and the other end of the first elastic piece is connected with the lock body, so that the lock pin is elastically connected to the lock body, and the lock pin is elastically inserted into the limit groove. In this embodiment, the first elastic member is compressed when the lock pin moves away from the limit groove, and the elastic direction of the first elastic member to the lock pin is a direction toward the limit groove. Whether the electronic lock is in a locked state or an unlocked state, the first elastic piece is always in a compressed state. When locking, actuating mechanism drive lockpin inserts the spacing inslot, and first elastic component elasticity acts on the lockpin. When the lock is unlocked, the driving mechanism drives the lock pin to slide away from the limiting groove, and the first elastic piece is further compressed under the action of the lock pin. In this embodiment, the first elastic member is a coil spring, and in other embodiments, the first elastic member may also be an elastic glue.

In one embodiment, as shown in fig. 3, the lock pin 210 defines an open slot 212. The power output end of the driving mechanism is at least partially positioned in the open slot, and the power output end of the driving mechanism respectively acts on different positions of the inner wall of the open slot so as to drive the lock pin to be inserted into the limit slot. When the electronic lock is locked, the power output end of the driving mechanism rotates clockwise to act on the position, close to the limiting groove, of the inner wall of the open groove, so that the power output end of the driving mechanism drives the lock pin to move towards the direction close to the limiting groove until the lock pin is inserted into the limiting groove. When the electronic lock is unlocked, the power output end of the driving mechanism rotates anticlockwise to act on the position, far away from the limiting groove, of the inner wall of the open groove, so that the power output end of the driving mechanism drives the lock pin to move towards the direction far away from the limiting groove until the lock pin slides away from the limiting groove.

When the electronic lock is locked again, in order to enable the lock pin assembly to be quickly inserted into the limiting groove and realize quick locking of the electronic lock, in one embodiment, the power output end of the driving mechanism moves to the middle position of the open groove after the lock pin slides away from the limiting groove, and the power output end of the driving mechanism is not abutted to the lock pin at the moment.

The first elastic piece is sleeved on the boss part and abutted against the lock pin main body, so that the first elastic piece is reliably connected with the lock pin. In one embodiment, the latch body and the boss portion are welded together to securely connect the latch body to the boss portion. In other embodiments, the lock pin main body and the boss part can be integrally formed, so that the structure of the lock pin is more compact.

In one embodiment, the abutting block is welded on one side of the turntable adjacent to the lock pin assembly, so that the abutting block is firmly connected with the turntable. In other embodiments, the abutment block and the turntable may be formed separately and joined together by welding or gluing.

As shown in fig. 6, in one embodiment, the width of the opening 212a of the open slot 212 is greater than the width of the slot bottom 212b of the open slot, so as to achieve quick assembly and disassembly of the electronic lock. In one embodiment, the abutting block is located at an opening of the open slot. The driving shaft of the driving element is positioned at the groove bottom of the open groove. In this embodiment, the width of the groove bottom of the open groove is larger than the diameter of the drive shaft of the drive element, so that the drive shaft of the drive element can move in the groove bottom of the open groove. When the abutting block acts on the opening of the open slot and is close to the limiting slot, the driving shaft of the driving element abuts against the inner wall of the slot bottom of the open slot at the same time, so that the first elastic piece is prevented from being stretched excessively under the action of the lock pin, and the service life of the electronic lock is prolonged.

As shown in fig. 6 and 5, in one embodiment, the opening 212a of the open slot 212 is curved at a side away from the position of the arc assembly 2122.

The lock beam is arranged on the lock body in a sliding mode, and the limiting groove is formed in the lock beam. One end of the second elastic piece is connected with the lock beam, and the other end of the second elastic piece is connected with the lock body, so that the lock beam can elastically slide on the lock body. When the lock is locked, the lock beam assembly is pressed, the lock beam slides relative to the lock body, meanwhile, the second elastic piece is pressed until the lock beam assembly slides to a preset position relative to the lock body, the driving mechanism drives the lock pin assembly to be inserted into the limiting groove, and at the moment, the second elastic piece is compressed. When the driving mechanism drives the lock pin assembly to slide away from the limiting groove, the lock beam automatically resets under the action of the second elastic element, and the electronic lock is unlocked quickly. In this embodiment, the second elastic member is a coil spring, and in other embodiments, the second elastic member may also be an elastic glue.

As shown in fig. 2, in one embodiment, the shackle 310 includes a shackle body 312 having a U-shape, and a locking tongue portion 314 and a sliding portion 316 connected to both ends of the shackle body, respectively. In this embodiment, the shackle body, the tongue portion, and the sliding portion are integrally formed, so that the structure of the shackle is compact. In other embodiments, the strike body, the strike portion, and the slider portion may be formed separately and joined together by welding.

As shown in fig. 2, in one embodiment, the lock body 100 has a locking groove 110, and the bolt portion is used for being locked in the locking groove. In one embodiment, the sliding part is slidably disposed on the lock body, so that the lock beam is slidably disposed on the lock body. The limiting groove is formed in the sliding portion. In one embodiment, one end of the second elastic member is connected to the sliding portion, and the other end of the second elastic member is connected to the lock body, so that the lock beam is slidably connected to the lock body and connected to one end of the second elastic member. When the lock is locked, the lock beam body is pressed to move relative to the lock body, the lock tongue part and the sliding part move relative to the lock body along with the lock beam body until the lock tongue part is locked in the lock groove, the sliding part slides to a preset position relative to the lock body and enables the second elastic part to be extruded to generate elastic deformation, and at the moment, the driving mechanism drives the lock pin component to be inserted into the limiting groove to complete locking operation.

In one embodiment, as shown in fig. 2 and 3, the retaining groove 302 is formed around the perimeter wall of the strike 310 to allow for better insertion of the locking pin assembly into the retaining groove while saving material required for forming the strike. In this embodiment, the stopper groove 302 is opened around the peripheral wall of the sliding portion. In other embodiments, the retaining groove may be provided only at a position on the shackle that faces the locking pin assembly.

In one embodiment, as shown in fig. 3, the axial width of the retainer groove 302 in the strike is greater than the thickness of the locking pin assembly 200 within the retainer groove. When locking, the lock beam is pressed down, the lockpin moves towards the spacing groove under the elastic action of the first elastic piece, so that the lockpin is inserted into the spacing groove, because the width of the spacing groove is greater than the width of the lockpin, therefore, the lock beam can be continuously pressed down until the lockbeam slides to a preset position, the lockbeam is abutted to the switch component and presses the switch component, so that the driving mechanism is triggered to drive the lockpin to further move towards the spacing groove, and after the motor stops working, the motor is continuously abutted to the lockpin, the lockpin displacement is avoided, and the lockpin can be firmly clamped with the lockbeam. Therefore, when the lock pin assembly is inserted into the limiting groove, the lock beam still has a certain moving space relative to the lock body, the problem that the lock pin assembly or the lock beam is abraded greatly due to the fact that the lock beam is rigidly connected with the lock pin assembly in an inserting mode is avoided, and the service life of the electronic lock is prolonged. In this embodiment, the end of the lock pin far from the first elastic element is located in the limiting groove, and the thickness of the lock pin located in the limiting groove is smaller than the axial width of the limiting groove 302 in the lock beam.

In this embodiment, the first sliding channel 130 and the second sliding channel 140 are perpendicular to each other. The driving mechanism is positioned in the accommodating cavity. In one embodiment, the strike assembly is partially slidably disposed in the first slide channel such that the strike assembly is slidably disposed in the lock body. The switch assembly is arranged in the first sliding channel. In one embodiment, the locking pin assembly is slidably disposed in the second sliding channel such that the locking pin assembly is slidably disposed in the lock body. Because the lock beam assembly and the lock pin assembly are arranged in the lock body in a sliding mode, the lock beam assembly and the lock pin assembly are not easily corroded by external moisture, and the electronic lock is ensured to have a long service life.

As shown in fig. 4, specifically, the first slide passage 130 includes a slide passage portion 132 and a receiving portion 134 communicating with each other. The slide channel portion communicates with the second slide channel, communicating the first slide channel with the second slide channel. The strike beam assembly is positioned within the sliding channel portion and is slidably coupled to the lock body such that the strike beam assembly portion is slidably disposed within the first sliding channel. The switch assembly is arranged in the accommodating part, so that the switch assembly is arranged in the first sliding channel.

In one embodiment, the switch assembly 400 is located on one side of the path of the strike assembly 300, as shown in fig. 7. One side activity butt of lock beam subassembly in switch module presses the switch module, just the lock beam subassembly acts on the direction of the butt force of switch module with the slip direction of lock beam subassembly is crossing, makes the setting mode of switch module comparatively simple convenient. In this embodiment, the switch assembly 400 is disposed on the sidewall of the first sliding channel 130, the lock beam slides along the first sliding channel 130, and during the sliding process, the sidewall of the lock beam abuts against the switch assembly, so as to press the switch assembly. Because the switch assembly is positioned on one side of the sliding path of the lock beam assembly, the lock beam assembly can quickly touch the switch assembly, and the moving stroke of the switch assembly is shortened.

As shown in fig. 5, 7 and 8, in one embodiment, the switch assembly 400 includes a movably connected switch body 410 and an abutment 420. The switch body is disposed on the lock body 100 and electrically connected to the driving mechanism.
