[0023] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0024] like Figures 1 to 7 As shown, this case provides a car key that is easy to assemble and disassemble, specifically comprising a front cover 1, a middle frame 2 snapped onto the top of the front cover 1, and a back cover 3 snapped onto the bottom of the middle frame 2. The middle frame 2 is used to connect the front cover 1 and the back cover 3 and provide structural support. The provision of the middle frame 2 simplifies the connection between the front cover 1 and the back cover 3, thereby improving the structural stability. In a specific implementation, in order to enhance the user's hand feel, the middle frame 2 can be made of metal to increase the weight of the car key of this case. A keypad 4 and a circuit board 5 are detachably connected to the front cover 1. The keypad 4 fits tightly against the inner side of the front cover 1. One side of the circuit board 5 fits tightly against the keypad 4. A button battery 6 that can be detachably connected to the circuit board 5 to form a modular and integrally detachable assembly is detachably connected to the circuit board 5. A telescopic antenna 7 located on one side of the button battery 6 is fixedly connected to the circuit board 5. A mounting hole 11 for rotatably connecting the telescopic antenna 7 is provided at the top of the front cover 1. In this case, mounting hole 11 is provided at the top of the front cover 1. It allows the telescopic antenna 7 to be pivoted and extended within the mounting hole 11 as needed. Mounting hole 11 provides a mounting location for the telescopic antenna 7, making it easy for the user to quickly locate and install the circuit board 5. Connecting posts 12 are provided within the front cover 1 to facilitate the installation and positioning of the keypad 4 and circuit board 5. Connecting posts 12 are fixedly connected to the rear cover 3. Screws 8 secure connecting posts 12, making assembly and disassembly of the rear cover 3 and front cover 1 more convenient and efficient, while also ensuring a stable connection.

[0025] To assemble the car key, the user simply lifts the front cover, aligns the keypad 4 with the connecting post 12, and presses it down. Then, lifts the circuit board 5, inserts the telescopic antenna 7 into the mounting hole 11, rotates the circuit board 5, aligns it with the connecting post 12, and presses it down. Finally, the middle frame 2 is snapped into place with the front cover 1, and the rear cover 3 is aligned with the connecting post 12 to secure it. This structural design of the car key is easy to assemble and disassemble. To replace the button battery 6, the user simply removes the rear cover 3 to conveniently replace it.

[0026] like Figure 1-Figure 5As shown, further, in the specific implementation, in order to ensure a stable and quick connection, this case adopts a symmetrical setting method, and two connecting columns 12 are symmetrically arranged above and below. Corresponding screw holes 31 are opened on the back cover 3, and screws 8 that pass through the screw holes 31 and are connected to the connecting columns 12 are installed in the screw holes 31.

[0027] Specifically, in order to achieve rapid positioning and post-installation fixation of the keypad 4 and the circuit board 5, refer to Figure 1-Figure 3 As shown, a first through hole 41 for the connecting column 12 to pass through is correspondingly opened on the key board 4, and a second through hole 51 for the connecting column 12 to pass through is correspondingly opened on the circuit board 5.

[0028] like Figure 1-Figure 5 As shown, specifically, to facilitate quick assembly and connection between the front cover 1 and the middle frame 2, a first positioning groove 13 is provided on the inner sidewall of the upper end of the front cover 1, and a first positioning ridge 21 is provided on the side of the middle frame 2 facing the front cover 1, which inserts into the first positioning groove 13. The first positioning groove 13 is used to cooperate with the first positioning ridge 21 on the middle frame 2 to achieve positioning between the front cover 1 and the middle frame 2. A clamping strip 14 is formed on the inner sidewall of the lower end of the front cover 1, and a clamping portion 22 is provided on the side of the middle frame 2 facing the front cover 1, which inserts into the clamping strip 14. The clamping strip 14 is used to cooperate with the clamping portion 22 on the middle frame 2 to achieve a clamped connection and fixation between the front cover 1 and the middle frame 2. The coordinated design of the first positioning ridge 21, the first positioning groove 13, the clamping portion 22, and the clamping strip 14 simplifies the connection process between the front cover 1 and the middle frame 2, and improves the stability and accuracy of the connection.

[0029] like Figure 1-Figure 5 Specifically, to facilitate quick assembly and connection between the rear cover 3 and the middle frame 2, second positioning grooves 23 are symmetrically provided on the left and right sides of the middle frame 2, facing the rear cover 3. Second positioning ridges 32 are formed on the inner sidewalls of the rear cover 3 to insert into the second positioning grooves 23. In practice, to further secure the connection between the rear cover 3 and the middle frame 2, two sets of second positioning ridges 32 and second positioning grooves 23 are provided. The coordinated arrangement of the second positioning ridges 32 and second positioning grooves 23 facilitates faster assembly and securement between the middle frame 2 and the rear cover 3, ensuring the reliability and durability of the car key during use.

[0030] like Figure 1-Figure 7As shown, the front cover 1 is further provided with a first function key area 100 and a second function key area 200. In specific implementations, the first function key area 100 and the second function key area 200 provide different function key areas to facilitate different user operations. By dividing the function key areas into different areas, user convenience and intuitiveness are improved. A sliding cover 15 is slidably connected to the front cover 1, capable of sliding to cover either the first function key area 100 or the second function key area 200. In specific implementations, the user can selectively cover either the first function key area 100 or the second function key area 200 by sliding the sliding cover 15, preventing accidental operation. The design of the sliding cover 15 enhances the security and user experience of the car key, preventing users from accidentally pressing keys in a function key area when not in use. Function keys 52 are provided on the circuit board 5 to correspond to the first function key area 100 and the second function key area 200 on the front cover 1, implementing different key functions.

[0031] like Figure 1-Figure 7 As shown, the circuit board 5 is further provided with a lamp bead 53, and the keypad 4 is correspondingly provided with a lamp cover 42 for shielding the lamp bead 53 and allowing light to pass through. The lamp cover 42 passes through the front cover 1 and is exposed on the outer surface of the front cover 1. The lamp cover 42 is designed in conjunction with the lamp bead 53 so that the light emitted by the lamp bead 53 can be directly irradiated to the outside, ensuring that the user can clearly see the status of the indicator light.

[0032] As mentioned above, this case protects a car key that is easy to disassemble and assemble. All technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
