[0028] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0029] Figure 1This is a disassembled view of the front shell 1, rear shell 3, and connector 2 of this case, and is a front view of the interior direction of the front shell 1 and rear shell 3 after they are disassembled. For the description of the front, rear, left, and right parts and their positional relationships in this case, please refer to Figure 1 Directions shown in .

[0030] like Figures 1 to 8 As shown, the case provides a car key that is easy to disassemble and assemble, including a front shell 1, a connecting member 2 clamped at the lower end of the front shell 1, and a rear shell 3 that is covered on the front shell 1 by clamping with the connecting member 2. A first clamping structure is provided between the connecting member 2 and the front shell 1, a first connecting block 21 is provided on the connecting member 2, a first groove 11 clamped with the first connecting block 21 is provided on the front shell 1, and a second groove 31 clamped with the first connecting block 21 is provided on the rear shell 3. It should be noted that the first clamping structure can also be provided between the connecting member 2 and the rear shell 3, but relatively speaking, it is more inconvenient to disassemble and assemble the rear shell 3 and the front shell 1, because the front shell 1 of the car key in the prior art is equipped with various parts, and the rear shell 3 is generally designed to be hollow inside to cover the front shell 1 and avoid various parts. If the first clamping structure is provided between the connecting member 2 and the rear shell 3, the user has to first connect the rear shell 3 with the connecting member 2, and then cover the front shell 1 on the rear shell 3, which is more inconvenient.

[0031] As described above, when the front shell 1 and the rear shell 3 are assembled, the first connection block 21 of the connector 2 is inserted into the first groove 11 on the front shell 1. At the same time, due to the first clamping structure, the connector 2 is clamped and fixed with the front shell 1, and then the rear shell 3 is covered and closed, and the first connection block 21 of the connector 2 is clamped into the second groove 31 on the rear shell 3, so that the front shell 1 and the rear shell 3 are easily clamped together to complete the assembly. When disassembling, because the front shell 1 and the rear shell 3 are clamped and tightly sealed, it is convenient for the disassembly and assembly of the two while also ensuring that the connection between the two is stable, so the user generally needs to use tools to find the gap at the connection, and then only needs to pry up the rear shell 3, so that the first connection block 21 on the connector 2 is out of the second groove 31 on the rear shell 3, and the rear shell 3 can be taken out. The design of this structure in the present case is simple in structure, occupies less internal space of the front shell 1 and the rear shell 3, has fewer components, is convenient for reducing the overall volume of the car key, and is more lightweight and easy to carry. At the same time, it makes the disassembly, maintenance and production assembly between the front shell 1 and the rear shell 3 simpler and faster.

[0032] like Figure 1-Figure 7As shown, in the specific implementation, in order to further improve the stability of the connection between the rear shell 3 and the front shell 1, and at the same time realize the convenient and quick disassembly and assembly between the two. In this case, the second clamping structure, the third clamping structure, the fourth clamping structure, the fifth clamping structure and the limit structure are also provided between the rear shell 3 and the front shell 1 to facilitate the disassembly and assembly between the rear shell 3 and the front shell 1. It should be noted that in the specific implementation, the second clamping structure, the third clamping structure, the fourth clamping structure, and the fifth clamping structure are all arranged at the outer side of the front shell 1 and the rear shell 3 to avoid occupying the internal space of the front shell 1 and the rear shell 3.

[0033] Specifically, Figure 1-Figure 6 As shown, the first clamping structure includes a first protrusion 22 provided on the connecting member 2, and a first clamping groove 12 provided on the front shell 1 and clamped with the first protrusion 22. Two first protrusions 22 and two first clamping grooves 12 are respectively provided. Of course, the first protrusion 22 and the first clamping groove 12 can also be provided as one or more than two. Relatively speaking, in this case, two are preferably provided so that the front shell 1 and the rear shell 3 can be connected and tightened, and the two can also be easily disassembled.

[0034] It should be noted that, accordingly, in a specific implementation, the first clip structure can also be set to a structure in which the first clip slot 12 is set on the rear shell 3 and the first protrusion 22 is set on the front shell 1. Accordingly, the second clip structure, the third clip structure, the fourth clip structure, and the fifth clip structure can all be set in this possible way.

[0035] Specifically, Figure 1-Figure 6 As shown, the second snap-fit ​​structure includes a second protrusion 33 arranged on the right side of the rear shell 3, and a second slot 13 arranged on the left side of the front shell 1 and snap-fitted with the second protrusion 33. The second protrusion 33 and the second slot 13 are respectively and correspondingly arranged with two. The upper end of the second slot 13 is provided with a first inclined surface 81 for facilitating the second protrusion 33 to be snapped into the second slot 13, that is, the first inclined surface 81 is arranged on the front shell 1 and is located at the upper end of the second slot 13, so that the second protrusion 33 slides through the first inclined surface 81 and then snaps into the second slot 13 more easily, further facilitating the assembly of the rear shell 3 and the front shell 1. Of course, the second protrusion 33 and the second slot 13 can also be correspondingly arranged to be one or more than two. Relatively speaking, the case is preferably arranged to be two so that the front shell 1 and the rear shell 3 can be connected and tightened while also facilitating the disassembly and assembly of the two. In this case, the explanation and description of the number of second protrusions 33 and second slots 13 similar to the second snap-fit ​​structure will not be repeated in the following text.

[0036] Specifically, Figure 1-Figure 6As shown, the third snap-fit ​​structure includes a third protrusion 14 arranged on the right side of the front shell 1, and a third snap-fitting groove 34 arranged on the left side of the rear shell 3 and snap-fitting with the third protrusion 14. Two third protrusions 14 and third snap-fitting grooves 34 are respectively arranged to cooperate with each other. The upper end of the third snap-fitting groove 34 is provided with a second inclined surface 82 for facilitating the third protrusion 14 to snap into the third snap-fitting groove 34, that is, the second inclined surface 82 is arranged on the rear shell 3 and located at the upper end of the third snap-fitting groove 34, so that the third protrusion 14 slides through the second inclined surface 82 and then snaps into the third snap-fitting groove 34 more easily, further facilitating the assembly of the rear shell 3 and the front shell 1.

[0037] Specifically, Figure 1-Figure 6 As shown, the fourth clamping structure includes a fourth protrusion 15 arranged at the lower end of the front shell 1, and a fourth clamping groove 35 arranged at the lower end of the rear shell 3 and clamped with the fourth protrusion 15. Two fourth protrusions 15 and four clamping grooves 35 are respectively provided for corresponding cooperation. The upper end of the fourth clamping groove 35 is provided with a third inclined surface 83 for facilitating the fourth protrusion 15 to be clamped into the fourth clamping groove 35, that is, the third inclined surface 83 is arranged on the rear shell 3 and located at the upper end of the fourth clamping groove 35, so that the fourth protrusion 15 slides through the third inclined surface 83 and then is more easily clamped into the fourth clamping groove 35, which further facilitates the assembly of the rear shell 3 and the front shell 1.

[0038] Specifically, Figure 1-Figure 6 As shown, the fifth clamping structure includes a fifth protrusion 16 arranged on the right side of the front shell 1 and a fifth clamping groove 36 arranged on the left side of the rear shell 3 and clamped with the fifth protrusion 16. Two fifth protrusions 16 and five clamping grooves 36 are respectively arranged to cooperate with each other.

[0039] Specifically, Figure 1-Figure 6 As shown, the limiting structure includes a first positioning groove 17 provided in the front shell 1, a first connecting column 37 provided in the rear shell 3 for inserting into the first positioning groove 17, and the limiting structure also includes a second positioning groove 18 provided in the front shell 1, and a second connecting column 38 provided in the rear shell 3 for inserting into the second positioning groove 18. The setting of the limiting structure facilitates rapid positioning when the front shell 1 and the rear shell 3 are covered, prevents misalignment, and realizes faster assembly, and can also further improve the stability of the two after being connected.

[0040] like Figure 1-Figure 8As shown, further, a first installation cavity 101 is provided inside the front shell 1, and a second installation cavity 102 communicating with the first installation cavity 101 is provided outside the front shell 1. The first installation cavity 101 and the second installation cavity 102 provide space for installing corresponding components on the front shell 1. A key board 4 detachably connected to the front shell 1 and a circuit board 5 detachably connected to the front shell 1 and attached to the key board 4 are installed in the first installation cavity 101. That is, the key board 4 is attached to the bottom of the first installation cavity 101, and the circuit board 5 is installed on the back of the key board 4, that is, the side facing the rear shell 3. In specific implementation, a battery is provided on the side of the circuit board 5 facing the rear shell 3, and the battery on the circuit board 5 can be replaced by opening the rear shell 3. A key cover 6 is detachably installed in the second installation cavity 102, and the key board 4 includes an outer key portion 41, which extends into the first installation cavity 101 and is connected to the key cover 6, so that the user can operate the key portion 41. The key cover 6 is provided with an indicator mark 61 to remind the user of the function corresponding to the indicator mark 61 on the key cover 6, which is convenient for use. In specific implementation, the key part 41 can be set to three, four or more than four to match the different functions of different car keys, such as unlocking, unlocking, trunk, etc. The indicator mark 61 on the key cover 6 can be set by laser / silk screen printing. It should be noted that the detachable connection between the detachable key plate 4, circuit board 5, and key cover 6 described here is preferably a card connection, which is easier to disassemble and assemble than the screw connection. Of course, it can also be a screw connection and riveting method. The key plate 4, circuit board 5, key cover 6, front shell 1, connector 2, and rear shell 3 of this case can all be detachably connected, and the disassembly and assembly are more thorough, and there are fewer parts, no more connection fixation and pre-processing work is required, 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.

[0041] like Figure 1-Figure 8 As shown, further, the car key of this case also includes a key blade 7 that is rotatably connected to the front shell 1. In specific implementation, the key blade 7 is hinged on the front shell 1. The front shell 1 is provided with a button switch that can automatically pop out the key blade 7. When the circuit board 5 is damaged or the battery is out of power, the user can use the key blade 7 to unlock. The connecting member 2 is provided with a hanging hole 20, which is convenient for the user to carry the car key of this case. Further, the first positioning groove 17 and the second positioning groove 18 are set on the circuit board 5. After assembly, the circuit board 5 is limited and fixed by the first connecting column 37 and the second connecting column 38 on the rear shell 3 to prevent the circuit board 5 from being displaced inside the front shell 1 when in use, such as when the car key falls, causing damage to the circuit board 5. The fifth protrusion 16 is set on the key board 4, which is conducive to the connection stability between the key board 4 and the front shell 1 and the rear shell 3, and prevents the key board 4 from being displaced and misaligned with the corresponding position of the circuit board 5, thereby affecting the use of the key part 41.

[0042] 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.
