[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Please refer to the following: Figures 1 to 5 The car key protective cover 10 provided in this application embodiment will now be described. The car key protective cover 10 includes: an upper metal frame 11, a lower metal frame 12, an upper covering 13, and a lower covering 14.

[0036] The upper metal frame 11 and the lower metal frame 12 can be assembled together to form a mounting cavity for covering the periphery of the car key. The upper metal frame 11 and the lower metal frame 12 cover the periphery of the car key and confine the car key within the upper metal frame 11 and the lower metal frame 12. The upper metal frame 11 has an upper hollow portion 111 that penetrates its upper and lower surfaces. The upper covering member 13 is installed on the upper metal frame 11 and covers the upper hollow portion 111. The lower metal frame 12 has a lower hollow portion 121 that penetrates its upper and lower surfaces. The lower covering member 14 is installed on the lower metal frame 12 and covers the lower hollow portion 121. The lower surface of the upper metal frame 11 has a triangular arrangement of screw holes, and the lower metal frame 12 has a triangular arrangement of through holes. Screws pass through the through holes and are screwed into the screw holes to lock the upper metal frame 11 and the lower metal frame 12.

[0037] The process of assembling the car key onto the car key cover 10 is as follows: First, the upper cover 13 is installed on the upper metal frame 11 and covers the upper hollow part 111, and the lower cover 14 is installed on the lower metal frame 12 and covers the lower hollow part 121; then, the car key is placed into the lower metal frame 12, and the upper metal frame 11 and the lower metal frame 12 are pressed against each other so that the upper metal frame 11, the lower metal frame 12, the upper cover 13 and the lower cover 14 completely cover the car key. Finally, the upper metal frame 11 and the lower metal frame 12 are locked together by screws passing through the through holes and screwing them into the screw holes.

[0038] Specifically, in the first aspect, by setting an upper metal frame 11 and a lower metal frame 12 to cover the periphery of the car key, and by setting an upper covering part 13 and a lower covering part 14 to cover the upper and lower surfaces of the car key respectively; such a structure can provide the car key with good impact resistance while ensuring that the signal receiving ability of the car key is not reduced, and also achieve good wear resistance.

[0039] Secondly, by setting up triangularly arranged screw holes and triangularly arranged through holes, the upper metal frame 11 and the lower metal frame 12 can be locked by screwing the screws through the through holes and connecting them into the screw holes. The locking state is stable and reliable, which helps to reduce the phenomenon of the upper metal frame 11 and the lower metal frame 12 falling off during long-term use.

[0040] In some embodiments, the upper cover 13 includes a first main body 131 and a first mounting strip 132 disposed at the edge of the first main body 131, and the lower surface of the upper metal frame 11 is provided with a first mounting step 112; when the upper cover 13 is installed over the upper hollow portion 111, the first mounting strip 132 can be disposed on the first mounting step 112, and the first main body 131 protrudes upward from the upper hollow portion 111. The lower cover 14 includes a second main body 141 and a second mounting strip 142 disposed at the edge of the second main body 141, and the upper surface of the lower metal frame 12 is provided with a second mounting step 122; when the lower cover 14 is installed over the upper hollow portion 111, the second mounting strip 142 can be disposed on the second mounting step 122, and the second main body 141 protrudes downward from the lower hollow portion 121.

[0041] Specifically, the thickness of the first assembly strip 132 is equal to or greater than the height of the first assembly step 112, and the thickness of the second assembly strip 142 is equal to or greater than the height of the second assembly step 122. The thicknesses of the first assembly strip 132 and the second assembly strip 142 are the same. With this structure, after the upper and lower metal parts are assembled together, the first assembly strip 132 and the second assembly strip 142 can be deformed, so that the first assembly strip 132 is firmly embedded in the first assembly step 112 and the second assembly strip 142 is firmly embedded in the second assembly step 122. This ensures that the upper cover 13 and the lower cover 14 will not shake during actual use. The upper cover 13 and the lower cover 14 will only undergo elastic deformation when the user activates the corresponding button on the car key using the upper cover 13 or the lower cover 14.

[0042] Preferably, the upper metal frame 11 and the lower metal frame 12 are made of any one of stainless steel, aluminum alloy, titanium alloy or zinc alloy. This structure can provide strong support for the car key with the help of the upper metal frame 11 and the lower metal frame 12 made of metal materials, so that it has good drop resistance. The upper cover 13 and the lower cover 14 are made of leather or silicone material. This structure can improve wear resistance and will not hinder the signal reception capability of the car key.

[0043] In other embodiments, the screw holes include a first screw hole 113, a second screw hole 114, and a third screw hole 115. The first screw hole 113 and the second screw hole 114 are located on the rear side of the lower surface of the upper metal frame 11, with the first screw hole 113 and the second screw hole 114 spaced apart from each other. The third screw hole 115 is located on the front side of the lower surface of the upper metal frame 11 and is situated between the first screw hole 113 and the second screw hole 114. The through holes include a first through hole 123, a second through hole 124, and a third through hole 125. The first through hole 123 and the second through hole 124 are located through the rear side of the lower metal frame 12, with the first through hole 123 and the second through hole 124 spaced apart from each other. The third through hole 125 is located through the front side of the lower metal frame 12 and is situated between the first through hole 123 and the second through hole 124.

[0044] When the upper metal frame 11 and the lower metal frame 12 are assembled together, the first through hole 123 and the first screw hole 113 are coaxially arranged, the second through hole 124 and the second screw hole 114 are coaxially arranged, and the third through hole 125 and the third screw hole 115 are coaxially arranged. A screw can be threaded through the first through hole 123 into the first screw hole 113, through the second through hole 124 into the second screw hole 114, and through the third through hole 125 into the third screw hole 115. In other words, the upper metal frame 11 and the lower metal frame 12 can be secured using only three screws, making assembly convenient.

[0045] Specifically, the lower surface of the upper metal part is integrally formed with a first assembly cylinder 116, a portion of which protrudes toward the first assembly step 112, and the lower surface of the first assembly cylinder 116 is provided with a first positioning protrusion 117; the upper surface of the lower metal part is integrally formed with a second assembly cylinder 126, a portion of which protrudes toward the second assembly step 122, and the upper surface of the second assembly cylinder 126 is provided with a second positioning groove 127, into which the first positioning protrusion 117 is inserted.

[0046] More specifically, the third screw hole 115 penetrates the lower surface of the first positioning protrusion 117, and the third through hole penetrates the bottom of the second mounting groove and the lower surface of the lower metal part. A second positioning protrusion 118 is provided on the lower surface of the upper metal part at positions corresponding to the first screw hole 113 and the second screw hole 114, with the first screw hole 113 and the second screw hole 114 respectively penetrating the lower surface of the corresponding second positioning protrusion 118; a third positioning groove 128 is provided on the upper surface of the lower metal part at positions corresponding to the first through hole and the second through hole, with the first through hole and the second through hole respectively penetrating the bottom of the corresponding third positioning groove 128.

[0047] Preferably, the distance by which the first assembly cylinder 116 protrudes towards the first assembly step 112 is one-half or one-third of the width of the first assembly step 112, and the distance by which the second assembly cylinder 126 protrudes towards the second step is one-half or one-third of the width of the second assembly step 122. This structure ensures that the upper metal frame 11 and lower metal frame 12 can be made thinner and lighter, while ensuring that the triangularly arranged screw holes can reliably provide screw engagement, preventing screws from piercing the screw holes during screw insertion, thus improving service life. Furthermore, the first assembly strip 132 has a first clearance notch 133 for avoiding the first assembly cylinder 116, and the second assembly strip 142 has a second clearance notch 143 for avoiding the second assembly cylinder 126. This allows for both clearance and positioning of the upper and lower covering parts 13 and 14, improving assembly convenience.

[0048] More specifically, the upper metal frame 11 is provided with a first hanging opening 119 between the first screw hole 113 and the second screw hole 114, and the first hanging opening 119 penetrates the upper and lower surfaces of the upper metal frame 11; the lower metal frame 12 is provided with a second hanging opening between the first through hole 123 and the second through hole 124, and the second hanging opening penetrates the upper and lower surfaces of the lower metal frame 12; the first hanging opening 119 and the second hanging opening are the same size and are coaxially arranged. When the upper metal frame 11 and the lower metal frame 12 are assembled together, the first hanging opening 119 and the second hanging opening can form a complete hanging opening, so that users can pass objects such as hanging ropes through the hanging opening.

[0049] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
