[0031] Please refer to Figures 1-6As shown, it shows the specific structure of the preferred first embodiment of the utility model, it is a car key protection shell, including first shell body 10 and second shell body 20 of up-down stacked assembly, two opposite adhering surfaces 1 of first shell body 10 and second shell body 20, one is provided with convex post 30, another is provided with buckle groove 40, convex post 30 is inserted with buckle groove 40;The thickness of the adhering surface 1 corresponding the position of buckle groove 40 is first interval A1, the inner wall of the deepest part of the inner cavity of buckle groove 40 is center point 41, the linear distance between center point 41 and the outside edge 11 of adhering surface 1 is second interval A2, second interval A2 is greater than or equal to one fifth of the length of first interval A1.The car key protection shell of the prior art, the buckle block and the buckle groove are arranged on the first shell body and the second shell body to increase the tightness of the first shell body and the second shell body after being overlapped, but when the car key protection shell is pursued for beauty and the symmetrical arc is arranged on the left and right side edges of the car key protection shell, the thickness of the left and right side edges of the car key protection shell needs to be increased to facilitate the opening of the buckle block and the buckle groove.The car key protection shell, by opening the convex post 30 and the buckle groove 40 on the first shell body 10 and the second shell body 20 at the same time, because the thickness of the adhering surface 1 corresponding the buckle groove 40 of the first shell body 10 and the second shell body 20 is the first interval A1, and the inner wall of the deepest part of the buckle groove 40 opened on the adhering surface 1 is the center point 41, the linear distance between the center point 41 and the outside edge 11 of the first shell body 10 or the second shell body 20 is the second interval A2, and the second interval A2 is about one fifth of the length of the first interval A1, so that the convex post 30 and the buckle groove 40 are opened to ensure the tightness of the first shell body 10 and the second shell body 20 after being overlapped without increasing the thickness of the adhering surface 1.

[0032] It should be noted that when the length of the first interval A1 is 1.3 cm, the length of the second interval A2 is between 0.3 cm and 0.4 cm, and if the length of the second interval A2 is 0.3 cm, the buckle groove 40 opened on the first shell body 10 or the second shell body 20 can facilitate the butt joint of the convex post 30 while ensuring the strength of the first shell body 10 or the second shell body 20, so as to avoid the buckling groove 40 from being deformed due to the thin second interval A2 caused by the opening of the buckle groove 40, which makes the outside edge 11 of the first shell body 10 or the second shell body 20 vulnerable to external pressure and collision when it is hit, affecting the use and appearance of the entire car key protection shell.

[0033] As Figure 5As shown, the inner side edge 12 is opposite to one side of the outer side edge 11 of the fitting surface 1, and the inner side edge 12 is provided with a notch 42 which is matched with and communicated with the buckling groove 40. When the first shell 10 and the second shell 20 are separated, the protruding column 30 and the buckling groove 40 are inserted, and the protruding column 30 can be moved out of the buckling groove 40 through the notch 41. The notch 41 and the buckling groove 40 are matched, and the shape of the combination of the notch 41 and the buckling groove 40 is slightly larger than a semicircle, so as to facilitate the insertion and extraction of the protruding column 30 in the buckling groove 40.

[0034] As shown, Figure 5 The center of the buckling groove 40 can be offset to the inner side edge 12 or the outer side edge 11, so as to increase / decrease the length of the second distance A2. The center of the buckling groove 40 is A3, and the extension of the center A3 of the buckling groove 40 to the inner side edge 12 increases the length of the second distance A2, so as to avoid the buckling groove 40 from being deformed by extrusion and collision when the outer side edge 11 of the first shell 10 or the second shell 20 is impacted, and affect the use and appearance of the whole car key protection shell. When the center of the buckling groove 40 is offset to the outer side edge 11, the size of the buckling groove 40 can be increased, the volume of the protruding column 30 matched with the buckling groove 40 is increased, and the problem that the protruding column 30 is easily broken when it is thin is avoided.

[0035] The protruding column 30 is matched with the buckling groove 40, and the protruding column 30 and the buckling groove 40 are away from the outer side edge 11. By setting the protruding column 30 and the buckling groove 40 away from the outer side edge 11 and close to the inner side edge 12, when the first shell 10 and the second shell 20 are buckled, the whole car key protection shell is more beautiful and has higher tightness.

[0036] As shown, Figure 4 The length of the protruding column 30 is a fourth distance A4, the depth of the buckling groove 40 is a fifth distance A5, and the fifth distance A5 is longer than the fourth distance A4. The fifth distance A5 corresponds to the depth of the buckling groove 40, and the fourth distance A4 corresponds to the height of the protruding column 30. Since the fifth distance A5 is longer than the fourth distance A4, the insertion of the protruding column 30 and the buckling groove 40 is loose, so as to facilitate the insertion and separation of the protruding column 30 and the buckling groove 40.

[0037] As shown, Figure 4As shown, the length of the fourth distance A4 is greater than or equal to two-thirds of the length of the fifth distance A5. The length of the fourth distance A4 is between 0.5 cm and 0.7 cm. When the length of the fourth distance A4 is 0.5 cm, the length of the fifth distance A5 is 0.6 cm to ensure that the protruding column 30 and the snap-fit groove 40 are loosely fitted. When the length of the fourth distance A4 is 0.7 cm, the length of the fifth distance A5 is 0.9 cm. The length of the fifth distance A5 can be between 0.6 cm and 0.9 cm to match the length of the fourth distance A4.

[0038] As shown in FIG. 4, the protruding column 30 is inserted into the snap-fit groove 40. As shown, the length of the fourth distance A4 is greater than or equal to two-thirds of the length of the fifth distance A5. Figure 4 As shown, the length of the fourth distance A4 is greater than or equal to two-thirds of the length of the fifth distance A5. The length of the fourth distance A4 is between 0.5 cm and 0.7 cm. When the length of the fourth distance A4 is 0.5 cm, the length of the fifth distance A5 is 0.6 cm to ensure that the protruding column 30 and the snap-fit groove 40 are loosely fitted. When the length of the fourth distance A4 is 0.7 cm, the length of the fifth distance A5 is 0.9 cm. The length of the fifth distance A5 can be between 0.6 cm and 0.9 cm to match the length of the fourth distance A4.

[0039] In addition, because the first shell 10 and the second shell 20 are assembled in a stacked manner, the flatness of the first shell 10 and the second shell 20 may be deviated due to manufacturing reasons when the first shell 10 and the second shell 20 are assembled. In this case, the sixth distance A6 can ensure that the first shell 10 and the second shell 20 are assembled in a stacked manner to overcome the difference in flatness of the first shell 10 and the second shell 20 to a certain extent, so that the first shell 10 and the second shell 20 are more tightly connected.

[0040] As shown in FIG. 4, the protruding column 30 is inserted into the snap-fit groove 40. As shown, the length of the fourth distance A4 is greater than or equal to two-thirds of the length of the fifth distance A5. Figure 6 As shown, the length of the fourth distance A4 is greater than or equal to two-thirds of the length of the fifth distance A5. The length of the fourth distance A4 is between 0.5 cm and 0.7 cm. When the length of the fourth distance A4 is 0.5 cm, the length of the fifth distance A5 is 0.6 cm to ensure that the protruding column 30 and the snap-fit groove 40 are loosely fitted. When the length of the fourth distance A4 is 0.7 cm, the length of the fifth distance A5 is 0.9 cm. The length of the fifth distance A5 can be between 0.6 cm and 0.9 cm to match the length of the fourth distance A4.

[0041] When the snap-fit groove 40 is a circular groove, the radius of the snap-fit groove 40 is consistent with the seventh distance A7.

[0042] When the diameter of the snap-fit groove 40 is greater than the length of the first interval A1, the radius of the snap-fit groove 40 is greater than or equal to three-sixths of the length of the first interval A1. When the length of the first interval A1 is 1.3 cm, the radius of the snap-fit groove 40 is 0.5 cm-0.7 cm, and the diameter of the snap-fit groove 40 is 1 cm-1.4 cm. When the length of the second interval A2 is 0.4 cm, the radius of the snap-fit groove 40 is 0.5 cm or greater. After the convex column 30 is loosely inserted into the snap-fit groove 40, and the left and right side edges of the first shell 10 and the second shell 20 are provided with the arc, the left and right side edges still have good support strength.

[0043] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application. Any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still falls within the scope of the technical solution of the present application.
