[0036] See Figures 8 to 10 As shown, the rear cover 20 includes a top wall 201 and side walls 202 extending downwards from all sides of the top wall 201. The side walls 202 cover the outer side of the main body 103 and slide along the stepped surface 1021. A fixing groove 203 is provided on the rear side wall 202 for the decorative strip 70 to extend into and be fixed. The rear cover 20 is provided with a third fastener 21, a fourth fastener 22, and a sixth fastener 23. In the embodiments of this application, there are two third fasteners 21, three fourth fasteners 22, and four sixth fasteners 23.

[0037] A pair of third latching members 21 are disposed on the front side of the rear cover 20, and a pair of first latching members 11 are correspondingly disposed with the pair of third latching members 21. The third latching members 21 cooperate with the first latching members 11 to limit the lower inner cover 10 and the rear cover 20 in the front-back direction. Specifically, the third latching member 21 protrudes downward from the rear cover 20, and the third latching member 21 includes a guide surface 211 located on the front side and inclined downward and backward, and a latching surface 212 located on the rear side and inclined downward and forward.

[0038] The snap-fit ​​surface 212 of the third snap-fit ​​member 21 engages with the hook portion 112 of the first snap-fit ​​member 11. The guide surface 211 can automatically guide the elastic arm 111 to undergo elastic deformation and drive the hook portion 112 into the correct position when sliding closed. The snap-fit ​​surface 212 and the hook portion 112 form a firm barbed lock, ensuring that it will not come loose due to vibration after locking.

[0039] A pair of fourth latches 22 are located on the rear side of the rear cover 20, and a pair of second latches 12 are correspondingly provided with the pair of fourth latches 22.

The fourth latches 22 include a protrusion 221 protruding forward and downward from the rear cover 20 and a hook 222 extending forward from the end of the protrusion 221. The hook 222 is engaged in the groove 123 from the rear side forward.

[0040] This application establishes a stable multi-directional limiting structure by setting a first group and a second group of fasteners that limit the movement in the front-back direction and the up-down direction, namely a pair of first fasteners 11 and a pair of third fasteners 21, a pair of second fasteners 12 and a pair of fourth fasteners 22. This structure effectively restrains the rear cover 20 and the lower inner cover 10 in all directions, significantly enhancing the connection reliability of the overall structure and effectively preventing loosening and abnormal noise caused by daily drops, collisions or squeezing.

[0041] According to other embodiments of this application, the number of the third fastener 21 and the fourth fastener 22 is not limited to a pair, and can also be multiple to achieve better stability. This application does not impose any limitations on this.

[0042] According to an embodiment of this application, a fourth latching member 22 is located between a pair of third latching members 21 and on the front side of the rear cover 20. The fourth latching member 22 located between the pair of third latching members 21 is correspondingly arranged with the second latching member 12 located between a pair of first latching members 11. By adding an L-shaped fourth latching member 22 and a second latching member 12 between the main latching groups in the front-rear direction, the rear cover 20 is effectively prevented from swaying in the left-right direction or from slightly twisting around the axis relative to the lower inner cover 10, further improving the overall rigidity and fitting accuracy of the smart key.

[0043] A pair of sixth latches 23 are provided on each of the left and right sides of the back cover 20. The sixth latches 23 cooperate with the fifth latches 13 to limit the key body and the back cover 20 in the front-back and left-right directions. The sixth latches 23 include a connecting part 231 protruding inward along one side of the back cover 20 and a slot 232 provided on the connecting part 231. The protrusion engages with the slot 232, and the hook 142 of the latch 14 extends into the top of the connecting part 231 to engage with the connecting part 231.

[0044] According to other embodiments of this application, the left-right limiting of the rear cover 20 and the lower inner cover 10 can be achieved without the use of a snap-fit ​​device, but rather by designing the side wall of the rear cover 20 as a guide rail that matches the inner wall of the lower inner cover 10. The snap-fit ​​device 14 engages with the connecting part 231, forming a double safety mechanism that greatly enhances the reliability and resistance to failure of the connection.

[0045] PCBA30 is located between the lower inner cover 10 and the sealing gasket 80. The upper cover assembly 40 includes an upper inner cover 41 and a decorative cover 42, with the upper inner cover 41 located between the sealing gasket 80 and the decorative cover 42. The battery cover 60 covers the battery 50, and the battery 50 and the battery cover 60 are located between the lower inner cover 10 and the rear cover 20. The decorative strip 70 is located on the rear side of the lower inner cover 10 and the rear cover 20, and is sandwiched between the lower inner cover 10 and the rear cover 20.

[0046] The smart key also includes a positive electrode spring 90, which is disposed between the lower inner cover 10 and the PCBA 30. According to an embodiment of this application, the smart key is assembled as follows: First, the decorative cover 42 and the upper inner cover 41 are assembled; then, the sealing gasket 80 and the PCBA 30 are assembled, and the positive electrode spring 90 is assembled onto the PCBA 30. Next, the lower inner cover 10 is assembled, and the battery 50 is assembled into the battery receiving cavity 101, with the battery cover 60 covering the top of the battery 50. Finally, the decorative strip 70 and the back cover 20 are assembled.

[0047] This application utilizes two sets of latches positioned at the upper limits in both the front-to-back and up-down directions to effectively constrain the back cover 20 and the key body in multiple directions, significantly enhancing the connection reliability of the smart key. Furthermore, the smart key can be easily opened and closed by simply sliding the back cover 20 against the key body, making maintenance and disassembly convenient.
