As shown in FIG. 3 and FIG. 4 , the above-mentioned limit platform 211 is optionally connected to the above-mentioned groove bottom wall 111 by magnetic attraction, bonding or snap connection. The above-mentioned connection method is simple and reliable, and is easy to process. It can realize the stable connection between the groove bottom wall 111 and the sliding column 210, prevent the pendant 200 from accidentally falling off, and facilitate the pulling out of the pendant 200, thereby improving the user experience. Furthermore, the above-mentioned upper cover 102 is connected to the above-mentioned lower cover 103 through the locking screw 101. The upper cover 102 and the lower cover 103 are buckled together to achieve good sealing, so that the electrical structure in the key body 100 is isolated from the external environment and protected, so that the car key has good waterproof, dustproof and anti-static effects. Specifically, the upper cover 102 and the lower cover 103 are connected using locking screws 101, which not only has a good fixing effect, but also facilitates disassembly, thereby efficiently maintaining the internal electrical structure and reducing maintenance costs.

Specifically, the present embodiment adopts magnetic connection between the groove bottom wall 111 and the sliding column 210. Optionally, the above-mentioned limit table 211 is provided with a first magnetic sheet 212, and the above-mentioned groove bottom wall 111 is provided with a second magnetic sheet 112 attracted to the above-mentioned first magnetic sheet 212. Furthermore, one of the first magnetic sheet 212 and the second magnetic sheet 112 is a magnet, and the other is an iron sheet or another magnet with opposite magnetic properties. In the present embodiment, the first magnetic sheet 212 and the second magnetic sheet 112 are two magnets of opposite polarities attracted to each other, which can realize the magnetic connection between the sliding column 210 and the above-mentioned groove bottom wall 111. The magnetic connection method occupies a small space, has high connection stability, is easy to disconnect, has a long service life, is simple to process and is pollution-free, and will not be elaborated here.

Furthermore, at least two second magnetic sheets 112 are arranged at intervals along the second direction. In this embodiment, two second magnetic sheets 112 are arranged, which are arranged at the position of the groove bottom wall 111 corresponding to the sliding column 210 when the pendant 200 is attached to the key body 100, and at the position of the groove bottom wall 111 corresponding to the sliding column 210 when the pendant 200 is pulled out. Of course, more than two second magnetic sheets 112 can also be arranged, so that the size of the pendant hole 201 can be changed to suit different pendant requirements.

As a preferred embodiment, the thickness of the pendant 200 is not greater than the thickness of the key body 100. The pendant 200 thus arranged will not exceed the thickness of the key body 100, so that when the pendant 200 is attached to the key body 100, its volume is smaller, and the appearance can be integrated, which is more convenient to store.
