Because spring bolt 22 is used for with clamping part 111 joint, so spring bolt 22's needs have certain volume and can guarantee that first splint 221 and second splint 222 are fixed with clamping part 111 centre gripping, if directly be connected spring bolt 22 with rack 233, can lead to mounting hole 211 trompil diameter to enlarge, be unfavorable for the sealed protection to the inner chamber. Meanwhile, in order to facilitate transmission between locking bolt 22 and rack 233, push-pull shaft 237 is arranged on locking bolt 22, locking bolt 22 is arranged outside lock body 21, so that the diameter of the opening of mounting hole 211 is reduced, the thrust of rack 233 is transmitted to push-pull shaft 237 through push-pull shaft 237, and locking bolt 22 is driven to move through push-pull shaft 237, so that smooth movement of locking bolt 22 is ensured, and the diameter of the opening of mounting hole 211 can also be reduced.

When the lock 2 is switched from the lock-off state to the lock-on state, the driving motor 231 is started to drive the screw 232 to rotate, the screw 232 sequentially drives the first gear 235 and the second gear 236 to rotate to increase the torque, and the second gear 236 drives the rack 233 to horizontally move towards one side of the second inductive switch 25. At this time, the shaft sleeve 2331 abuts against the second stop 2372 and drives the push-pull shaft 237 to move toward the second inductive switch 25 until the push-pull shaft 237 triggers the second inductive switch 25, and the unlocking process is finished. When the lock 2 is switched from the unlocking state to the locking state, the driving motor 231 is started to drive the screw 232 to rotate, the screw 232 sequentially drives the first gear 235 and the second gear 236 to rotate to increase the torque, and the second gear 236 drives the rack 233 to horizontally move towards one side of the first inductive switch 24. At this time, bushing 2331 abuts against first stop 2371 and drives push-pull shaft 237 to move toward first inductive switch 24 until bolt 22 triggers first inductive switch 24, and the locking process is finished.

The shaft sleeve 2331 and the rack 233 are of an integrally formed structure, so that the structural strength of the shaft sleeve 2331 and the rack 233 is improved, and the problem that the normal unlocking and locking functions of the lockset 2 cannot be realized due to the fact that the shaft sleeve 2331 and the rack 233 are broken in the using process of the lockset 2 is avoided.

Optionally, as shown in fig. 1 to 9, a first spring 238 is disposed between the bushing 2331 and the second stop 2372, and a second spring 239 is sleeved on one end of the guide shaft 234 close to the second inductive switch 25; specifically, one side of the second spring 239 close to the rack 233 may be an annular structure sleeved on the guide shaft 234, and when the lock 2 is in the unlocking state, the rack 233 abuts against the annular structure of the second spring 239, so that the second spring 239 is compressed. Or a third baffle 2341 and a fourth baffle 2342 are arranged at one end close to the second inductive switch 25, and the second spring 239 is arranged between the third baffle 2341 and the fourth baffle 2342; third baffle 2341 is the annular plate body, and the mobilizable cover of third baffle 2341 is established on guiding axle 234, and second spring 239 both ends are fixed respectively on third baffle 2341 and fourth baffle 342. The first spring 238 and the second spring 239 can limit the push-pull shaft 237, so as to prevent the driving motor 231 from continuously operating and damaging the lock body 21 due to the damage of the first inductive switch 24 or the second inductive switch 25.

When the lock 2 is in the locked state, the first spring 238 is in a compressed state; in order to avoid the overlarge impact force caused by the lock tongue 22 on the first inductive switch 24 in the long-term use process, by arranging the first spring 238 between the bushing 2331 and the second baffle 2372, when the lockset 2 is switched from the unlocking state to the locking state, the first spring 238 is gradually compressed by the acting force of the bushing 2331, so that the damage to the first inductive switch 24 caused by the overlarge impact force on the first inductive switch 24 is avoided while the lock tongue 22 can trigger the first inductive switch 24. Simultaneously, when tool to lock 2 is in the off-lock state, first baffle 2371 supports and blocks on the lateral wall of the inner chamber of mounting hole 211 week side, plays the effect of prescribing a limit to the displacement volume of spring bolt 22, even first inductive switch 24 damages, and the unable stop work of driving motor 231 can further guarantee that spring bolt 22 can not lead to the fact too big impact to first inductive switch 24 through the cooperation of first baffle 2371 and inner chamber lateral wall.

When the lock 2 is in the unlocking state, the second spring 239 is in a compressed state. Accordingly, in order to prevent the impact force of the push-pull shaft 237 on the second sensor switch 25 from being excessive during a long period of use, the third blocking plate 2341 is located farther from the second sensor switch 25 than the fourth blocking plate 2342 by providing the third blocking plate 2341 and the fourth blocking plate 2342 on the guide shaft 234, and the first spring 238 is provided between the third blocking plate 2341 and the fourth blocking plate 2342. When the lock 2 is switched from the locked state to the unlocked state, the rack 233 body exerts an acting force on the third baffle 2341, and the second spring 239 is gradually compressed, so that the push-pull shaft 237 can trigger the second inductive switch 25, and the second inductive switch 25 cannot be damaged due to too large impact force on the second inductive switch 25.

Optionally, as shown in fig. 1 to 9, a reed switch 26 is disposed in the inner cavity at a position corresponding to the plug 11, an end of the plug 11 has magnetism, and when the plug 11 is close to the reed switch 26, the reed switch 26 is turned on. When the bolt 11 is far away from the reed switch 26, the reed switch 26 is in an off state, and when the bolt 11 is close to the reed switch 26, the reed switch 26 is in an on state. A circuit board 212 is arranged in the lock 2, the driving motor 231, the reed switch 26 and the like are connected with the circuit board 212, and the conduction signal of the reed switch 26 is transmitted into the processor through the circuit board 212. Taking the sharing bicycle as an example, after the user finishes using the bicycle, the user needs to lock the bicycle and return the helmet 1, and the user selects the locking operation through software such as APP or applet, and at this time, the user brings the helmet 1 close to the reed pipe 26, and aligns the bolt 11 with the reed pipe 26. At this time, the reed switch 26 senses the magnetic field at the end of the plug 11, switches from the off state to the on state, and transmits an on signal to the processor, and the processor controls the driving motor 231 to start. The driving motor 231 controls the screw 232 to rotate, and the screw 232 drives the first gear 235 and the second gear 236 to rotate at a time, and simultaneously the rotation of the second gear 236 drives the rack 233 to move laterally. Rack 233 moves from a position close to second inductive switch 25 to a position close to first inductive switch 24, and drives push-pull shaft 237 and lock tongue 22 to move towards first inductive switch 24 until first clamping plate 221 and second clamping plate 222 clamp clamping portion 111, and first clamping plate 221 and second clamping plate 222 trigger first inductive switch 24. The lock 2 is fixed on the helmet 1, and the user can return the electric bicycle, so that the electric bicycle sharing device is very simple and convenient.

Specifically, as shown in fig. 1 to 9, a magnetic sheet having magnetism may be inserted into an end portion of the latch 11, or a magnetic coating may be coated on an end portion of the latch 11, so that the latch 11 may be inserted into the lock 2, which is not particularly limited herein.
