[0024] The housing module 100 includes a first housing 110, a second housing 120 and a fixed partition 130, wherein the first housing 110 and the second housing 120 are fixedly connected and the fixed partition 130 is located between the first housing 110 and the second housing 120; a first lock placement area 111, a second lock placement area 112 and a motor placement area 113 are provided on one side of the first housing 110 close to the fixed partition 130, and the fixed partition 130 covers the first lock placement area 111, the second lock placement area 112 and the motor placement area 113 (so that the components placed in the area are stably installed);

[0025] The sensor module 200 includes a circuit board 210, an NFC receiver 220, a battery 230 and a motor 240. The circuit board 210 is electrically connected to the NFC receiver 220 and the motor 240 respectively. The motor 240 is installed in the motor placement area 113 and a rotating block 250 is provided at the driving end of the motor 240.

[0026] The lock module 300 includes a U-shaped lock 310, a locking structure 320, a first spring 330 and a second spring 340. One end of the U-shaped lock 310 and the first spring 330 are both installed in the first lock placement area 111 and the first spring 330 is sleeved on one end of the U-shaped lock 310. The other end of the U-shaped lock 310, the locking structure 320, and the second spring 340 are all installed in the second lock placement area 112. The locking structure 320 is provided with a spring mounting groove 321 and a locking tongue 322. The other end of the U-shaped lock 310 is provided with a locking groove 311. The second spring 340 is installed in the spring mounting groove 321 and the locking tongue 322 faces the locking groove 311.

[0027] Specifically, the first shell 110 is provided with a first groove portion 114, a second groove portion 115, a third groove portion 116 and a fourth groove portion 117 around it, and the second shell 120 is provided with a first barb 121, a second barb 122, a third barb 123 and a fourth barb 124 around it, the first barb 121 is installed in the first groove portion 114, the second barb 122 is installed in the second groove portion 115, the third barb 123 is installed in the third groove portion 116, and the fourth barb 124 is installed in the fourth groove portion 117 (to achieve a detachable connection between the first shell and the second shell).

[0028] More specifically, the first shell 110 is provided with a first fixing hole 118, and the fixed partition 130 is provided with a second fixing hole 131, and the first fixing hole 118 and the second fixing hole 131 are aligned (the first fixing hole and the second fixing hole are fixed by bolts, so that the fixed partition is installed on the second shell).

[0029] Furthermore, the locking structure 320 is further provided with a push block 323 , and the push block 323 is located at one side of the rotating block 250 .

[0030] Furthermore, an NFC placement area is provided on the outer side of the first housing 110 (for prompting the NFC transmitter to approach the area so as to interact with the NFC receiver).

[0031] The principle of the utility model is:

[0032] When unlocking is required, the NFC transmitter is close to the NFC placement area, thereby performing near-field communication with the built-in NFC receiver, and after the circuit board determines that it is successful, it drives the motor to rotate, so that the rotating block pushes the pushing block to move, and then the locking structure moves away from the other end of the U-shaped lock, the second spring is compressed, and the lock tongue disengages from the lock groove, so that the other end of the U-shaped lock is unlocked. Since the first spring is provided on one end of the U-shaped lock, the first spring is initially compressed. Therefore, after the other end of the U-shaped lock is not subjected to force, due to the restoring force of the first spring, the U-shaped lock moves up as a whole, thereby completing the unlocking.

[0033] It is worth mentioning that the technical features such as the NFC transmitter involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.

[0034] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
