[0002] With the continuous development of technology in the automotive field, the technology of automotive parts is also changing with each passing day. Among them, car keys are also constantly improving, from traditional mechanical keys and remote control keys to the current smart keys. As the name suggests, smart keys are smarter than traditional remote control keys. Users only need to carry smart keys to remotely open or close the car doors, as well as other corresponding functions. Users do not need to operate the smart keys during use, which truly embodies intelligence. However, the problem that follows is that smart keys consume more power than traditional remote control keys, and the frequency of battery replacement also increases. This requires smart keys to be easier to operate in the battery replacement function module. For this reason, a smart key with an automatically pop-up back cover is proposed.

Specifically, the smart key also includes a back cover mounting groove matching the shape of the back cover 2 on the back of the key body 1; a card block 1 4 is provided at the rear of the key body 1, and a card block 2 5 matching the shape of the card block 1 4 is provided at the inner rear of the back cover 2; a top block 6 is provided in the middle of the key body 1, and a convex block 7 corresponding to the position of the top block 6 is provided at the inner middle of the back cover 2; a button accessory 3 is provided at the front end of the key body 1; when the smart key covers the back cover 2, the rear part of the back cover 2 is clamped through the card block 2 5 and the card block 1 4, the convex block 7 is abutted against the top block 6, and the front part of the back cover 2 is continuously pressed downward, the back cover 2 is deformed and the front part of the back cover 2 is clamped into the button accessory 3, thereby fixing the back cover 2 on the key body 1; when the smart key opens the back cover 2, the front end of the button accessory 3 is pressed, the button accessory 3 releases the front part of the back cover 2, and the back cover 2 overcomes its own deformation and automatically pops out to restore its original state.

[0029] The front bottom of the key body 1 is provided with a button installation groove 8 ; the button accessory 3 is arranged in the button installation groove 8 .

[0030] The front end of the key body 1 is provided with a button slot 9 ; the button accessory 3 includes a button head 10 disposed at the front end and in the button slot 9 .

[0031] The button accessory 3 includes a functional part 13 arranged at the rear and a spring mounting part 11 at the front bottom, and a spring mounting hole 12 is provided at the rear end of the spring mounting part 11; a spring baffle 14 is provided at the front of the key body 1 below the functional part 13, and a spring 15 is provided between the spring baffle 14 and the spring mounting hole 12. The spring 15 is a stainless steel spring, which is used to realize the pushing and automatic resetting of the button accessory 3, and the button accessory 3 is preferably made of die-cast zinc alloy material.

[0032] The front end of the rear cover 2 is connected downwardly with a hook 16, and a rear guide surface 17 is provided on the rear side of the bottom of the hook 16; the functional part 13 includes a buckle block 18 arranged at the rear, and a buckle groove 19 is provided in the buckle block 18; the top front side of the buckle block 18 is provided with a front guide surface 22 that cooperates with the rear guide surface 17.

[0033] A front limiting surface 20 is disposed at the front side of the bottom of the barb 16 ; the functional portion 13 includes a limiting block 21 disposed at the front.

[0034] The contact surfaces of the front limiting surface 20 and the limiting block 21 are both inclined surfaces.

[0035] The back cover 2 is made of plastic and has a certain elasticity, so it is easy to pop out.

[0036] The use method and working principle of the utility model: Assuming that the rear cover 2 and the key body 1 are initially in a separated state, the structure of the key body 1 is referenced Fig.10 When the rear cover 2 needs to be assembled, the block 2 5 of the rear cover 2 is clamped on the front side of the block 1 4. At this time, in the natural state, the protrusion 7 is against the top block 6, and the front part of the rear cover 2 naturally tilts up. The front part of the rear cover 2 is continuously pressed downward, and the rear cover 2 is deformed. The barb 16 moves downward, and the rear guide surface 17 contacts the front guide surface 22. Continue to press, and the button accessory 3 overcomes the pulling force of the spring 15 and moves a small end to the left. Then the barb 16 moves down to the height of the buckle groove 19, and the spring 15 is quickly retracted to reset the button accessory 3. The barb 16 is smoothly clamped into the buckle groove 19, and the assembly of the rear cover 2 is completed. At this time, the structure is referenced. Figure 1 .

[0037] When it is necessary to open the rear cover 2 to replace the battery or take out the mechanical key, the button head 10 is pressed to overcome the compression spring 15, and the button accessory 3 moves to the left. When the front limit surface 20 contacts the limit block 21, the barb 16 just exits the buckle groove 19. At this time, the rear cover 2 is deformed to a certain extent when it is inserted into the button accessory 3. When the barb 16 exits the buckle groove 19, the rear cover 2 is not restrained and will quickly return to its natural state, that is, the protrusion 7 is against the top block 6, and the front part of the rear cover 2 is naturally tilted. At this time, the structure refers to Fig. 9 Because the above steps are completed in an instant, it feels like the operator only needs to press the button head 10, and the front part of the rear cover 2 can be quickly and automatically popped out, and the rear cover 2 can be quickly opened after it pops out.
