[0002] A car key is a crucial component for opening and closing car doors, and it consists of sub-components such as an upper cover, a lower cover, and key teeth.
[0003] Car mechanical keys have both functional and aesthetic requirements. Typically, the mechanical key must match the car door lock cylinder to meet the functional requirements of mechanically opening and closing the car door. It must also be simple and convenient to use to open and close the car door. In addition, the car mechanical key is carried on one's person and must have an attractive appearance to meet the aesthetic requirements of a mechanical key.
[0004] Current car mechanical keys typically consist of a handle and key teeth. The exposed key teeth allow others to see the tooth pattern, making this information easily leaked and posing a threat to vehicle security and theft prevention.
[0005] Moreover, most existing car key covers use a snap-fit connection structure, which can only be opened by prying with tools. This prying method damages the appearance and internal structure of the car key, making it inconvenient for customers and resulting in a poor user experience. Summary of the Invention
[0006] To address the aforementioned issues, a concealed sliding structure car mechanical key is provided, aiming to improve vehicle security and anti-theft performance, facilitate user use, enhance the user experience, improve the overall appearance and quality of the mechanical key, and avoid damage to the appearance and internal structure of the mechanical key caused by the opening method.
[0007] The specific technical solution is as follows:

The upper cover can slide along the lower cover and snap onto the lower cover to seal the key teeth inside the upper and lower covers.
[0009] Furthermore, the upper cover has upper cover limiting grooves on the front and rear side walls, and the lower cover has lower cover limiting ribs that correspond to and cooperate with the upper cover limiting grooves.
[0010] Furthermore, the upper cover has upper cover limiting protrusions on the left and right side walls, and the lower cover has lower cover limiting buckles that correspond to and cooperate with the upper cover limiting protrusions.
[0011] Furthermore, the upper cover has guide grooves on the front and rear side walls, and the lower cover has guide blocks that correspond to and cooperate with the upper cover limit grooves. The lower cover guide blocks can be inserted into the upper cover guide grooves and then slide along the upper cover.
[0012] Furthermore, the lower cover is provided with an extension arm and a fin limiting buckle at the left and right ends opposite the key teeth.
[0013] Furthermore, multiple intermittent ribs are provided on the front and rear sides of the lower cover, respectively, opposite to the key teeth.
[0014] Furthermore, the top of the cover is provided with multiple clamping ribs relative to the top of the key teeth.
[0015] Furthermore, the bottom of the lower cover is provided with multiple support ribs relative to the bottom of the key teeth.
[0016] Furthermore, the upper cover is provided with an upper cover misalignment rib, and the lower cover is provided with a lower cover misalignment rib that cooperates with the upper cover misalignment rib.
[0017] Furthermore, the upper cover misalignment ribs and the lower cover misalignment ribs are perpendicular to each other.
[0018] The beneficial effects of the above scheme are:
[0019] The mechanical key provided by this utility model has an upper cover that can slide and lock onto a lower cover to seal the key teeth within the upper and lower covers. Unlike conventional snap-fit connections, the sliding locking structure effectively improves the user experience. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0031] The present invention will be further described below with reference to specific embodiments, but this is not intended to limit the present invention.
[0032] like Figures 1 to 8 As shown, the hidden sliding structure car mechanical key provided in the embodiment of this utility model includes an upper cover 1, a lower cover 3 and a key tooth 2. The key tooth 2 can be snapped onto the lower cover 3; the upper cover 1 can slide along the lower cover 3 and be snapped onto the lower cover 3 to seal the key tooth 2 inside the upper cover 1 and the lower cover 3.
[0033] The mechanical key provided by this utility model has an upper cover 1 that can be slidably locked onto a lower cover 3 to seal the key teeth 2 within the upper cover 1 and lower cover 3, thereby preventing the leakage of key tooth information and preventing potential vehicle security and theft risks. Unlike conventional snap-fit structures, with this sliding locking structure, the customer can remove the key teeth 2 by sliding the upper cover 1 and lower cover 3. Compared to conventional snap-fit structures, the sliding structure allows the key teeth 2 to be removed directly by sliding the upper cover 1 and lower cover 3 without the need for additional tools to pry it open, thus effectively improving the customer experience and preventing damage to the key's appearance and internal structure.
[0034] Furthermore, such as Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the upper cover 1 has upper cover limiting grooves 11 on its front and rear side walls, and the lower cover 3 has lower cover limiting ribs 31 that correspond to and cooperate with the upper cover limiting grooves 11. Thus, the upper cover 1 and the lower cover 3 are slidably locked together by the lower cover limiting ribs 31 and the upper cover limiting grooves 11. In use, when the upper cover 1 is placed on the lower cover 3, the lower cover limiting ribs 31 are inserted into the upper cover limiting grooves 11. Due to the outward protrusion of the lower cover limiting ribs 31, they can abut against the upper cover 1. Thus, the friction between the lower cover limiting ribs 31 and the upper cover 1 tightens the front and rear sides of the lower cover 3 onto the upper cover 1. Furthermore, as... Figure 2 As shown, the left side of the upper cover limiting groove 11 is provided with a 90° vertical surface structure, which facilitates the lower cover limiting rib 31 to slide into the upper cover limiting groove 11 and then retract, thereby realizing the sliding lock of the upper cover 1 and the lower cover 3; the right side of the upper cover limiting groove 11 is provided with a 60° inclined surface structure, which facilitates the lower cover limiting rib 31 to slide into the upper cover limiting groove 11, thereby realizing the smooth sliding of the upper cover 1 and the lower cover 3.
[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the upper cover 1 has upper cover limiting protrusions 12 on the left and right side walls, and the lower cover 3 has lower cover limiting buckles 32 that correspond to and cooperate with the upper cover limiting protrusions 12. Thus, the upper cover limiting protrusions 12 and the lower cover limiting buckles 32 ensure from the left and right ends that the lower cover 3 and the upper cover 1 will not have gaps due to warping and deformation of the parts after assembly, which would affect the quality and appearance.
[0036] Furthermore, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, to facilitate smoother sliding assembly between the upper cover 1 and the lower cover 3, the upper cover 1 has upper cover guide grooves 13 on its front and rear side walls, and the lower cover 3 has lower cover guide blocks 33 that correspond to and cooperate with the upper cover 1's limiting grooves. In use, the lower cover guide blocks 33 can be inserted into the upper cover guide grooves 13 first, and then the upper cover 1 and lower cover 3 can be slid. The lower cover guide blocks 33 slide along the 6° inclined surface structure at the bottom of the upper cover guide groove 13 (the lower cover guide blocks 33 have a corresponding 6° inclined surface structure, such as...). Figure 5 (As shown at the bottom of the lower cover guide block 33), the above-mentioned 6° inclined structure not only makes the sliding action smoother, but the inclined structure also makes the upper cover 1 and the lower cover 3 fit more tightly under the action of the lower cover guide block 33 and the upper cover guide groove 13.
[0037] Furthermore, such as Figure 1 , Figure 3 , Figure 6As shown, the lower cover 3 has extension arms 34 and fin-limiting buckles 35 at its left and right ends relative to the key tooth 2, respectively. In use, the key tooth 2 can be fixed from its left and right ends using the extension arms 34 and fin-limiting buckles 35. To prevent the key tooth from sliding forward and backward and causing abnormal noise, the lower cover 3 has multiple intermittent ribs 36 on its front and rear sides relative to the key tooth 2, thereby using the intermittent ribs 36 to fix the key tooth 2 from both front and rear directions. Furthermore, as... Figure 7 As shown, in order to facilitate fixing the key tooth 2 to the lower cover 3 and removing it from the lower cover 3 during use, the head of the extendable arm 34 is provided with a 30° inclined surface structure.
[0038] Furthermore, such as Figure 2 , Figure 3 , Figure 4 As shown, the upper cover 1 has multiple clamping ribs 14 on the top relative to the key tooth 2, and the lower cover 3 has multiple supporting ribs (not shown in the figure) on the bottom relative to the key tooth 2. With the above structure, the key tooth 2 can be fixed between the upper cover 1 and the lower cover 3 by means of the clamping ribs 14 and the supporting ribs, so as to avoid abnormal noise when pressing the upper cover 1 and / or the lower cover 3, and improve the user experience.
[0039] Furthermore, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, the upper cover 1 is provided with an upper cover misalignment rib 15, and the lower cover 3 is provided with a lower cover misalignment rib 36 that cooperates with the upper cover misalignment rib 15. The upper cover misalignment rib 15 and the lower cover misalignment rib 36 are perpendicular to each other. The upper cover misalignment rib 15 and the lower cover misalignment rib 36 are designed with a unique anti-misalignment structure for the assembly position and direction of the key tooth piece 2, that is, the key tooth piece 2 cannot be assembled in other assembly positions and directions.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the content of the present utility model specification should be included within the protection scope of the present utility model.
