[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] The utility model provides a grounding structure of a passive intelligent lock core, whose working principle is to set an upper copper-clad area and a lower copper-clad area on a PCB board, and to coat copper on the upper copper-clad area and the lower copper-clad area, and to utilize the copper coating to realize a rigid connection between the PCB board and the lock core, so as to achieve the purpose of improving the stability of the circuit board grounding and improving the use quality of the circuit board in the passive lock core.

[0018] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0019] like Figure 1 As shown, a grounding structure of a passive intelligent lock core includes a PCB board 1 arranged in the passive lock, an upper copper-clad area 2 arranged on the top edge of the PCB board, and a lower copper-clad area 3 arranged on both sides of the bottom of the PCB board, and the upper copper-clad area and the lower copper-clad area are both clad with copper; the PCB board is rigidly connected to the lock core through the copper cladding.

[0020] One end of the upper edge of the PCB board is connected to the lock core through a spring 4.

[0021] The upper copper-clad area 2 and two lower copper-clad areas 3 of the PCB board 1 itself are clad with copper at the contact position between the lock core and the surface of the PCB board 1, and a rigid connection is made to ensure the circuit is grounded. At the same time, the end of the circuit board is connected with a spring 4, so that the circuit board and the lock core are in elastic contact through the spring, which again ensures the stability of the circuit grounding.

[0022] The above is only a preferred implementation of the grounding structure of a passive smart lock core disclosed in the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all belong to the protection scope of the utility model.
