[0002] With the development of the automotive industry, car keys have evolved from traditional mechanical keys to smart keys integrating multiple electronic functions. However, existing car keys have some shortcomings in design and manufacturing, particularly in terms of structural complexity and ease of assembly and disassembly.

[0003] Specifically, existing car keys generally have a complex structure, typically containing numerous components such as a front cover, middle frame, rear cover, button board, circuit board, and battery. This complexity not only increases production costs but also complicates assembly and disassembly. This complex structure necessitates intricate connections between the various components to ensure stability, often using multiple screws for fixation. This method of connection is cumbersome, and to facilitate subsequent assembly, the screws and components are often not thoroughly disassembled, hindering the transportation of semi-finished products and increasing transportation and packaging costs. Transporting a fully assembled car key can easily lead to loosening of components during transit, affecting its final usability. Furthermore, the complexity of existing car keys makes self-assembly difficult for users, increasing their burden.

[0004] Therefore, providing a car key that is thoroughly disassembled and reassembled, saves on packaging and transportation costs of semi-finished products, and is convenient for users to assemble themselves has become an important issue that urgently needs to be addressed by those skilled in the art.

[0023] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0024] like Figures 1 to 6As shown, this invention provides a fully removable car key, specifically including a front frame 1, a side frame 2 snapped onto the side wall of the front frame 1, and a rear cover 3 snapped onto the rear side of the front frame 1. The front frame 1 serves as the front frame of the car key, used to mount the side frame 2 and the rear cover 3, and is connected to the side frame 2 and the rear cover 3 via a snap-fit ​​connection. The front frame 1 provides mounting positions for the side frame 2 and the rear cover 3, and forms a first receiving cavity 100 and a second receiving cavity 200 for mounting other components, effectively ensuring structural stability. The snap-fit ​​connection simplifies the connection process between the side frame 2 and the front frame 1 and the rear cover 3, making disassembly and assembly convenient. After the side frame 2 and the front frame 1 are snapped together, a first receiving cavity 100 is formed. A button plate 4 snapped onto the front frame 1 is installed in the first receiving cavity 100. The rear cover 3 closes onto the front frame 1 and the side frame 2, thereby sealing the first receiving cavity 100 and concealing the interior of the car key. A second receiving cavity 200 communicating with the first receiving cavity 100 is formed on the outer wall of the front frame 1. A button sleeve 5 that is snapped onto the front frame 1 is installed in the second receiving cavity 200. A third receiving cavity 300 is formed on the inner side of the rear cover 3. A circuit board 6 is detachably connected to the third receiving cavity 300. The detachable connection simplifies the replacement process of the circuit board 6, improves the convenience of disassembly and maintenance, and makes disassembly and assembly more convenient and thorough. A button battery 7 that can be modularly disassembled and assembled with the circuit board 6 is detachably connected to the side of the circuit board 6 facing the rear cover 3. The modular design of the circuit board 6 and the button battery 7 simplifies the disassembly and assembly process of the circuit board 6 and the button battery 7, and facilitates the replacement of the button battery 7. A hook 8 that snaps between the front frame 1 and the rear cover 3 is installed at the lower end of the two. The hook 8 is designed to hang or facilitate the user to carry the car key of this case. In specific implementation, the hook 8 is made of metal to increase the weight of the car key of this case and improve its texture. In practice, the car key in this case has an overall "S"-shaped streamlined design, which is more aesthetically pleasing and makes it easier for users to hold.

[0025] like Figure 1 , Figure 2 , Figure 4 , Figure 6As shown, in specific implementation, the circuit board 6 is equipped with at least three buttons 61, and the button plate 4 is equipped with at least three buttons 41 for pressing the buttons 61. The button sleeves 5 are equipped with at least three buttons 41 corresponding to each button 41. The buttons 61 provide function control; when the user presses the corresponding button, the button 61 triggers the corresponding function. By setting at least three buttons 61, multiple function controls are achieved, improving the functionality of the car key. In specific implementation, the user can also set four or more buttons 61 according to their needs to meet different functional requirements of the car key. In this case, a corresponding number of buttons 41 and button sleeves 5 are provided. The button sleeves 5 are printed with indicator marks 51, which provide function indications to the user, improving the intuitiveness and convenience of user operation. The front frame 1 has button holes 11 for the corresponding buttons 41 to be inserted, ensuring the accurate positioning of the buttons 41 and improving the stability of the button 41 installation.

[0026] Furthermore, such as Figures 1-3 As shown, to facilitate the assembly and disassembly of the rear cover 3 and the front frame 1, and to effectively ensure the stability of the connection between the two, the rear cover 3 includes an inner ring 31 formed between the third accommodating cavity 300 and the inner wall of the rear cover 3. The outer periphery of the inner ring 31 is provided with a plurality of evenly distributed first buckles 32. The front frame 1 is provided with first slots 12 located on the cavity wall of the first accommodating cavity 100 for the corresponding first buckles 32 to engage. Through the cooperative design of the evenly distributed first buckles 32 and the first slots 12, the connection stability between the rear cover 3 and the front frame 1 is improved, and the assembly process is simplified.

[0027] like Figure 1 , Figure 2 , Figure 4 As shown, to facilitate the assembly and disassembly of the side frame 2 and the front frame 1, ensure the stability of their connection, and facilitate rapid positioning and installation during assembly, a side protrusion 13 for connecting the side frame 2 is provided on the front frame 1. The side frame 2 has a snap-fit ​​hole 21 for the side protrusion 13 to be snapped out and exposed. The cooperation between the side protrusion 13 and the snap-fit ​​hole 21 simplifies the connection process between the front frame 1 and the side frame 2, enabling rapid positioning of their sides and improving the stability of their side connection. The upper end of the side frame 2 is covered by a limiting structure onto the front frame 1. A second buckle 22 is located above the snap-fit ​​hole 21 on the inner wall of the side frame 2, and the second buckle 22 snaps onto the side protrusion 13. The cooperation between the limiting structure, the second buckle 22, and the side protrusion 13 simplifies the connection process between the front frame 1 and the side frame 2, enabling rapid positioning of their upper ends and improving the stability of their upper connection.

[0028] Continue as Figure 1 , Figure 2 , Figure 4As shown, to further stabilize the connection between the side frame 2 and the front frame 1, and to meet the transportation needs of some users who assemble the two components, in this embodiment, a connecting piece 23 is provided on the inner side of the side frame 2 below the snap-fit ​​hole 21. A first screw hole 24 is provided on the connecting piece 23, and a corresponding second screw hole 14 is provided on the front frame 1 below the side protrusion 13. A screw 25 is installed in the first screw hole 24, passing through the first screw hole 24 and connecting to the second screw hole 14. This screw connection method further enhances the connection stability between the side frame 2 and the front frame 1, ensuring the overall structural robustness and meeting the needs of different users.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the limiting structure includes a protrusion 26 formed on the inner wall of the upper end of the side frame 2 and a limiting channel 15 disposed on the upper end of the front frame 1 for the protrusion 26 to be engaged and limited. The upper end of the front frame 1 is provided with a first limiting part 151 and a second limiting part 152, and the limiting channel 15 is formed between the first limiting part 151 and the second limiting part 152. The limiting structure of this invention facilitates quick positioning and connection between the front frame 1 and the side frame 2, and effectively improves the stability after the two are connected.

[0030] Reference Figure 1 , Figure 2 , Figure 6 As shown, furthermore, a bracket 9, which is snapped onto the front frame 1, is installed in the second accommodating cavity 200. The bracket 9 has a third buckle 91, and the front frame 1 has a second slot 16 for the third buckle 91 to be snapped into. The snap-fit ​​connection between the bracket 9 and the front frame 1 simplifies the installation process of the bracket 9. The button sleeve 5 is pressed and disposed in the second accommodating cavity 200 and connected to the bracket 9, with part of the bracket 9 exposed on the surface of the button sleeve 5. The bracket 9 provides support for the button sleeve 5 and ensures that the installation position of the button sleeve 5 is accurate, ensuring the installation stability of the button sleeve 5 and simplifying the installation process of the button sleeve 5. In specific implementation, the bracket 9 is made of metal and is exposed on the car key of this case to enhance the aesthetics and texture of the car key.

[0031] like Figure 1 , Figure 3 , Figure 5As shown, the rear cover 3 includes at least two connecting posts 33 disposed in the third accommodating cavity 300, and the circuit board 6 has corresponding connecting holes 62 for the connecting posts 33 to pass through. The cooperation between the connecting posts 33 and the connecting holes 62 simplifies the installation process of the circuit board 6 and the rear cover 2, and enables rapid positioning and installation of the circuit board 6, ensuring accurate positioning and stability after installation. The third accommodating cavity 300 also includes support posts 34 for supporting and pressing the circuit board 6. In specific implementation, the height of the support posts 34 is lower than the height of the connecting posts 33, so that the rear cover can support and press the circuit board 6 after being snapped together with the front frame 1, ensuring the stability of the circuit board 6 after installation.

[0032] As stated above, this case protects a completely disassembled car key, and all technical solutions that are the same as or similar to those in this case should be considered to fall within the scope of protection of this case.
