Two upper guide blocks and two lower guide blocks are provided, and both are arranged at the middle position inside the upper shell and the lower shell.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model sets a protection mechanism, inserts the automobile key through the upper notch and the lower notch into the protective shell formed by the upper shell and the lower shell. To prevent the mechanical key from falling off, the mechanical key has a stop groove to prevent the key from falling off. The mechanical key is directly inserted into the protective shell formed by the upper shell and the lower shell. The spring and the stopper cooperate to give a certain force to the groove of the mechanical key, so that the mechanical key cannot fall off from the protective shell. Adding a protective shell outside the metal key can improve the wear of the mechanical key by external objects and improve the aesthetics and commerciality of the key.

[0013] 2. The utility model adopts the setting of the installation fixing mechanism. When the upper shell and the lower shell are connected together, the elastic buckle is first inserted into the deep groove, and then the upper shell and the lower shell are squeezed to make the elastic buckle snap into the slot. When the elastic buckle is snapped into the slot, the clamping ring is also stuck in the limit groove, so that the upper shell and the lower shell are more aligned and not easy to shake, making the upper shell and the lower shell more convenient to connect and install. When squeezing the elastic buckle, the elastic buckle can be moved out of the slot, so that the upper shell and the lower shell are separated and processed, which makes it not only convenient to install, but also more convenient and quick to disassemble.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The automobile key with protection function comprises a protection mechanism and an installation and fixing mechanism. The protection mechanism comprises an upper shell 1. A guide rod 2 is fixedly connected to the inner side of the upper shell 1. A spring 3 is sleeved on the outer side of the guide rod 2. A stopper 4 is fixedly connected to one end of the guide rod 2. A lower shell 5 is arranged on the lower side of the upper shell 1. An upper notch 6 is provided on the surface of the upper shell 1. A lower notch 7 is provided on the surface of the lower shell 5. The lower notch 7 is arranged on the lower side of the upper notch 6. The spring 3 is arranged between the upper shell 1 and the stopper 4. The upper shell 1 and the lower shell 5 are spliced ​​and fixed together through the installation and fixing mechanism. Then, the car key is inserted into the protective shell formed by the upper shell 1 and the lower shell 5 through the upper notch 6 and the lower notch 7. In order to prevent the mechanical key from falling off, the mechanical key has a stopping groove to prevent the key from falling off. The mechanical key is directly inserted into the protective shell formed by the upper shell 1 and the lower shell 5. The spring 3 and the stopper 4 cooperate to give a certain force to the groove part of the mechanical key, so that the mechanical key cannot fall off from the protective shell. Adding a protective shell outside the metal key can improve the wear of the mechanical key by external objects and enhance the aesthetics and commerciality of the key.

[0021] In one aspect of the present embodiment, the mounting and fixing mechanism includes a collar 8, the lower side of the collar 8 is fixedly connected with an elastic buckle 9, the interior of the lower shell 5 is provided with a deep groove 10, the surface of the lower shell 5 is provided with a clamping groove 11, the collar 8 is fixedly connected to the lower side of the upper shell 1, the elastic buckle 9 is clamped inside the clamping groove 11, the upper surface of the lower shell 5 is provided with a limiting groove 12, the collar 8 is clamped inside the limiting groove 12, and the upper shell 1 and the lower shell 5 are docked together, so that the elastic buckle 9 first penetrates into the deep groove 10 The upper shell 1 and the lower shell 5 are then squeezed, so that the elastic buckle 9 is inserted into the slot 11. When the elastic buckle 9 is inserted into the slot 11, the clamping ring 8 is also stuck in the limiting groove 12, so that the upper shell 1 and the lower shell 5 are more aligned and not easy to shake, making the docking installation of the upper shell 1 and the lower shell 5 more convenient. When squeezing the elastic buckle 9, the elastic buckle 9 can be removed from the slot 11, so that the upper shell 1 and the lower shell 5 can be separated and processed, which makes it not only convenient to install, but also more convenient and quick to disassemble.

[0022] In one aspect of the present embodiment, an upper guide block 13 is fixedly connected to the top of the upper shell 1, and a lower guide block 14 is fixedly connected to the bottom of the lower shell 5. When the key is inserted into the protective shell formed by the upper shell 1 and the lower shell 5, the upper guide block 13 and the lower guide block 14 can limit the key to prevent the key from shaking up and down in the protective shell formed by the upper shell 1 and the lower shell 5, so that the key is more stably fixed in the protective shell through the cooperation of the spring 3 and the stopper 4.

[0023] Working principle of the utility model: when the car key with protection function is used, the upper shell 1 and the lower shell 5 are docked together, so that the elastic buckle 9 first penetrates into the deep groove 10, and then the upper shell 1 and the lower shell 5 are squeezed to make the elastic buckle 9 snap into the slot 11. When the elastic buckle 9 snaps into the slot 11, the clamping ring 8 will also be stuck in the limiting groove 12, so that the upper shell 1 and the lower shell 5 are more aligned and not easy to shake. Then the car key is inserted into the protective shell formed by the upper shell 1 and the lower shell 5 through the upper notch 6 and the lower notch 7. In order to prevent the mechanical key from falling off, there is a stopping groove on the mechanical key to prevent the key from falling off. The mechanical key is directly inserted into the protective shell formed by the upper shell 1 and the lower shell 5. The spring 3 and the stopper 4 cooperate to give a certain force to the groove of the mechanical key, so that the mechanical key cannot fall off from the protective shell. Adding a protective shell outside the metal key can improve the wear of the mechanical key by external objects. When squeezing the elastic buckle 9, the elastic buckle 9 can be moved out of the card slot 11, so that the upper shell 1 and the lower shell 5 are separated and processed, which can make disassembly more convenient.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
