[0033] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0034] like Figures 1 to 12 As shown, the present invention discloses a car key, including a front shell 1, in which a first installation cavity 100 is provided. The first installation cavity 100 is provided to facilitate installation of various components of the car key of the present invention in the front shell 1. Please refer to Figure 1 As shown in the orientation, the first installation cavity 100 is provided with a first fixing seat 2 detachably connected to the front shell 1, a key board 3 clamped on the first fixing seat 2, a circuit board 4 clamped on the key board 3, and a second fixing seat 5 clamped on the front shell 1, and a rear shell 6 clamped on the second fixing seat 5, which covers the front shell 1 and covers the first installation cavity 100. In specific implementation, according to the setting mode of this structure of the case, rapid disassembly and assembly are achieved. The disassembly steps of the car key of the case are preferably to disassemble the rear shell 6 first, and then disassemble the second fixing seat 5, the circuit board 4, the key board 3, and the first fixing seat 2 in sequence. The installation steps of the car key of the case can be performed in the reverse steps of the above disassembly steps, that is, first install the first fixing seat 2 into the front shell 1, and then install the first fixing seat 2, the key board 3, the circuit board 4, and the second fixing seat 5 in sequence, and finally clamp the rear shell 6 with the second fixing seat 5 to complete the assembly. In this case, the front shell 1, the first fixing seat 2, the keypad 3, the second fixing seat 5 and the rear shell 6 are all made of integral injection molding, which further facilitates the production of each component and saves production costs.

[0035] like Figure 1-Figure 4As shown, it is the first implementation method of realizing detachable connection between the front shell 1 and the first fixing seat 2 of this case. Specifically, the first fixing seat 2 is provided with a first screw hole 21 at the upper end and a connecting hole 22 at the lower end, the inner upper end of the front shell 1 is provided with a first connecting portion 11 and a first connecting column 12 at the lower end, the first connecting portion 11 is arranged at a position above the first fixing seat 2 so as to press the first fixing seat 2 into the front shell 1, the first connecting portion 11 is provided with a second screw hole 111 corresponding to the position of the first screw hole 21, the first connecting column 12 and the connecting hole 22 are both provided with an inner screw hole 88, and the first connecting column 12 extends into the connecting hole 22 to connect and fix the front shell 1 to the first fixing seat 2. In specific implementation, the first screw hole 21 is arranged at the upper end of the first fixing seat 2, and the first connecting portion 11 on the front shell 1 is correspondingly arranged at a corresponding position to facilitate installation. During installation, first push the front end of the first fixing seat 2 into the first connecting portion 11 on the front shell 1 so that the front end of the first fixing seat 2 is pressed into the front shell 1 by the first connecting portion 11, and then the first screw hole 21 of the first fixing seat 2 corresponds to the second screw hole 111 on the first connecting portion 11 on the front shell 1, and then use a screw to penetrate the second screw hole 111 from the first screw hole 21 downwards, so as to connect the front shell 1 and the upper end of the first fixing seat 2; then after the first connecting column 12 at the lower end of the front shell 1 extends into the connecting hole 22 of the first fixing seat 2, use a screw to penetrate the first connecting column 12 from the connecting hole 22 downwards, so as to connect and fix the lower end of the front shell 1 and the first fixing seat 2, and at the same time play a role of limiting. During specific implementation, in order to make the connection between the first fixing seat 2 and the front shell 1 more stable, the number of the first connecting portion 11 and the first screw hole 21 can be set to two or more correspondingly, and in this case, it is preferably set to two. This is the first implementation method for realizing a detachable connection between the front shell 1 and the first fixing seat 2. This limiting structure plus the implementation method of fixing by threaded connection effectively realizes a detachable connection between the front shell 1 and the first fixing seat 2. The two are firmly connected after being threaded.

[0036] Continue to refer to Figure 1-Figure 4, which is the second embodiment of the detachable connection between the front shell 1 and the first fixing seat 2 in this case. Specifically, the first clamping blocks 23 are symmetrically arranged on the two side walls of the first fixing seat 2, and the first clamping grooves 13 for the first clamping blocks 23 to be clamped are symmetrically arranged on the two sides of the inner wall of the front shell 1. Through the design of the above structure, the clamping connection between the first fixing seat 2 and the front shell 1 is realized. Compared with the previous embodiment, this clamping connection method saves the trouble of disassembling and assembling screws, making the disassembly and assembly between the front shell 1 and the first fixing seat 2 more convenient. It should be noted that in the specific implementation, in order to save the subsequent production and assembly steps and to ensure the stability of the connection between the front shell 1 and the first fixing seat 2, the structures described in the above two embodiments are generally used together. This structure of the present case is more thorough in disassembly and assembly, and has fewer parts and components. It does not require more connection, fixing and pre-processing work, and the assembly production efficiency is higher. At the same time, it is conducive to saving the transportation cost of semi-finished products, and the semi-finished products can be sold for users to assemble by themselves, which is more convenient. When the user makes the semi-finished car key for shipment, the first fixing seat 2 and the front shell 1 are first installed and fixed, and then shipped in bulk with other parts. That is to say, in order to facilitate the subsequent assembly of the entire car key, the first fixing seat 2 and the front shell 1 are generally assembled, and then only the keypad 3, the circuit board 4, and the second fixing seat 5 need to be installed in sequence, and finally the rear shell 6 and the second fixing seat 5 are snapped together to complete the assembly. Of course, under the premise of achieving the same functions and technical effects, users can also choose to use any of the above two implementations.

[0037] like Figure 1-Figure 6 As shown, the snap connection between the keypad 3 and the first fixing seat 2 in this case is realized by the structure described below. Specifically, a snap hook 24 is provided at the lower end of the first fixing seat 2, and a second mounting cavity 200 is opened at the rear side of the first fixing seat 2, and the keypad 3 is snapped into the second mounting cavity 200 through the snap hook 24. In specific implementation, two snap hooks 24 are symmetrically arranged, respectively arranged at the two ends of the first connecting hole 22, and the outer contour of the keypad 3 is adapted to the inner contour of the second cavity 200, so as to facilitate the tight snap connection between the keypad 3 and the first fixing seat 2. Through the above snap connection structure, the quick disassembly and assembly between the keypad 3 and the first fixing seat 2 is realized. The snap connection between the keypad 3 and the circuit board 4 in this case is realized by the structure described below. A third mounting cavity 300 is opened at the rear side of the keypad 3, and the circuit board 4 is snapped into the third mounting cavity 300. In specific implementation, the outer contour of the circuit board 4 is the same as the inner contour of the third mounting cavity 300 on the keypad 3, so as to facilitate the tight snap connection between the circuit board 4 and the third mounting cavity 300 of the keypad 3. The above-mentioned clamping structure realizes the quick disassembly and assembly between the circuit board 4 and the key board 3 .

[0038] like Figure 1-Figure 3 , Figure 7 , Figure 8As shown, the snap connection between the second fixing seat 5 and the front shell 1 in this case is realized by the structure described below. Specifically, a fourth installation cavity 400 is opened on the front side of the second fixing seat 5, and a first snap connection structure and a second snap connection structure are provided between the second fixing seat 5 and the front shell 1 to facilitate the disassembly and assembly between the two. The second fixing seat 5 covers the key board 3 and the circuit board 4 is placed in the fourth installation cavity 400. By setting the first snap connection structure and the second snap connection structure, the second fixing seat 5 and the front shell 1 are quickly disassembled and assembled. The setting of the fourth installation cavity 400 facilitates the covering of the circuit board 4, and can effectively protect the circuit board 4.

[0039] Specifically, Figure 1-Figure 3 , Figure 7 , Figure 8 As shown, the first clamping structure of the present case includes a second clamping block 51 arranged on the second fixing seat 5, and a second clamping groove 14 arranged on the inner side wall of the front shell 1 for the second clamping block 51 to be clamped into.

The second clamping structure includes a third clamping block 52 arranged on the second fixing seat 5, and a protrusion 15 arranged on the inner side wall of the front shell 1 for the third clamping block 52 to be clamped into and limit the third clamping block 52. In specific implementation, the protrusion 15 is arranged on the inner side wall of the upper end of the front shell 1, and an inclined surface is provided on the protrusion 15 to facilitate the clamping of the third clamping block 52.

[0040] like Figure 1 , Figure 2 , Figure 7-Figure 9 As shown, a plurality of fourth clamping blocks 61 are provided on the rear shell 6, and a plurality of clamping portions 53 for the fourth clamping blocks 61 to be clamped into are correspondingly provided on the second fixing seat 5. The clamping connection between the rear shell 6 and the second fixing seat 5 in this case is realized by the above-mentioned clamping structure. In specific implementation, in order to reduce the installation space and facilitate the limit avoidance during installation between the rear shell 6 and the second fixing seat 5, and at the same time, in order to make the connection between the two tighter after installation, the fourth clamping block 61 needs to be correspondingly arranged near the outer edge of the rear shell 6. Preferably, in this case, five fourth clamping blocks 61 are provided, and five clamping portions 53 for the fourth clamping blocks 61 to be clamped into are correspondingly arranged on the second fixing seat 5. Through the above-mentioned structure, the rapid disassembly and assembly between the rear shell 6 and the second fixing seat 5 is realized.

[0041] Furthermore, if Figure 1 , Figure 2 , Fig.10 As shown, the car key of this case also includes a key assembly that is inserted and removed from the lower end of the front shell 1. When the circuit board 5 is damaged or the battery is out of power, the user can use the key to unlock the car.

[0042] Specifically, the key assembly includes a key handle 71 and a key blade 72 plugged into the key handle. The key blade 72 of the present invention is detachably connected to the key handle 71 by plugging and unplugging, and the two can be disassembled and assembled with each other, so that the car key of the present invention can be adapted to key blades 72 of different models, and has good practicality. The second fixing seat 5 is provided with a key slot 54 for inserting the key blade 72. When the key assembly of the car key is in the storage state, the key blade 72 is inserted into the key slot 54 and inserted into the car key from the opening at the lower end of the key slot 54, thereby completing the plugging of the key assembly. The key handle 71 is provided with a plug-in hole 711, and the plug-in hole 711 is set for disassembly and assembly of the key blade 72 and the key handle 71. The plug-in hole 711 is used to realize the disassembly and assembly between the key blade 72 and the key handle 71, which is convenient for disassembly, maintenance and replacement of the two. The lower end of the key handle 71 is provided with a hanging hole 712, and the design of the hanging hole 712 is convenient for plugging and unplugging the key assembly, and convenient for users to carry the car key of the present invention.
