Description

Technical Field

[0001] The utility model relates to the field of automobile keys, and more specifically, to an automobile key protection shell. Background Art

[0002] In order to avoid deformation when dropped, the key protection shells on the market need to design a metal square fixed frame with compressive protection performance at the outer edge of the protection shell. However, the fixed frame makes the disassembly and installation of the key protection shell inconvenient, and the square frame has an uncomfortable hand feeling when held.

[0003] How to design a key protection shell that can balance the inconvenience of installation and deformation is an urgent problem to be solved. Summary of the Utility Model

[0004] The utility model aims to overcome at least one defect (shortcoming) of the above-mentioned prior art, and provides an automobile key protection shell, which is used to solve the problems that the disassembly and installation of the key protection shell are inconvenient and the key protection shell is easy to deform due to dropping, and the shape of the key protection shell cannot improve the poor hand-held experience and easy slipping of the user.

[0005] The technical solution adopted by the utility model is an automobile key protection shell, which includes a frame support and a protective layer. The frame support includes a first frame and a second frame that are movably connected. The width between the first frame and the second frame gradually decreases from bottom to top along the long axis direction and forms a sharp corner part. The width between the first frame and the second frame gradually increases from top to bottom along the long axis direction and forms a bottom. The protective layer wraps around the frame support to form a cavity.

[0006] It is beneficial that the movably connected frame support can not only strengthen the structural stability of the key protection shell, but also improve the convenience of disassembly and installation of the frame support. By the sharp corner part, the problem of poor hand feeling of the existing square frame support is weakened, and the anti-slip performance is enhanced by the protective layer. A larger space is formed by the cavity to accommodate the electronic module of the automobile key.

[0007] Further, the frame support further includes a clamping member arranged at the bottom. The sharp corner part includes a rotating shaft. The first frame and the second frame rotate horizontally around the rotating shaft and form an open or closed state with the clamping member. The connection line between the rotating shaft and the clamping member is inside the cavity.

[0008] It is beneficial to realize the relative rotation of the first frame and the second frame through the rotating shaft, which is convenient for disassembly and installation of the frame support and will not scatter and lose the first frame and the second frame at the same time, and can be disassembled and installed with one hand. The clamping member is used to realize the quick connection or disconnection of the first frame and the second frame with one hand, improving the disassembly and installation efficiency. It is beneficial to realize the force balance through the connection line between the rotating shaft and the clamping member inside the cavity, so that the frame support will not affect the service life due to unbalanced force under repeated disassembly and installation.

[0009] Further, the clamping member includes a support post, a locking post, and a movable member. The support post is fixed to the first frame at the bottom, the locking post is fixed to the second frame at the bottom, and the movable member rotates horizontally around the support post and engages or disengages from the locking post to form a closed or open state of the clamping member.

[0010] It is beneficial to provide a placement space for the key protection case through the first frame portion and the second frame portion for placing the vehicle key electronic module. The support post serves as a fulcrum for the opening or closing of the clamping member, and the locking post forms the engagement.

[0011] Further, the movable member includes an inner hook portion and a pressing portion. The inner hook portion is used to engage or disengage from the locking post, and the pressing portion is an indented arc surface.

[0012] It is beneficial to contact and engage the inner hook portion with the locking post. The indented arc surface of the pressing portion facilitates contact with the human hand. With a single hand, a user can apply force on the pressing portion to swing the movable member up and down around the support post to achieve engagement or disengagement with the locking post.

[0013] Further, the first frame includes a first frame portion, the second frame includes a second frame portion, and the distance between the support post and the first frame portion is less than the distance between the locking post and the second frame portion.

[0014] It is beneficial that the support post is closer to the frame bracket than the locking post. When squeezing the first frame and the second frame, it is easy to automatically engage the movable member with the locking post by gently pushing.

[0015] Further, the frame bracket further includes a first convex edge extending outward from the edge of the first frame portion and protruding above the first frame, and a second convex edge extending outward from the edge of the second frame portion and protruding above the second frame.

[0016] It is beneficial to increase the force-bearing areas of the first frame portion and the second frame portion through the first convex edge and the second convex edge respectively, thereby enhancing the anti-deformation ability of the frame bracket. At the same time, the first convex edge and the second convex edge increase the thickness of the cavity, strengthening the structural stability in the direction perpendicular to the first frame portion and the second frame portion.

[0017] Further, the first convex edge is arc-shaped and includes two first arc surfaces formed above and below the first frame portion respectively, and the two first arc surfaces are symmetrically arranged along the first frame portion; the second convex edge is arc-shaped and includes two second arc surfaces formed above and below the second frame portion respectively, and the two second arc surfaces are symmetrically arranged along the second frame portion.

[0018] It is beneficial to increase the feel of the frame bracket through the arc-shaped first convex edge and second convex edge. The two symmetrically arranged first arc surfaces form a first convex edge with balanced stress for the first frame part, and the two symmetrically arranged second arc surfaces form a second convex edge with balanced stress for the second frame part.

[0019] Furthermore, reinforcing ribs are provided on both the first frame part and the second frame part.

[0020] It is beneficial to improve the compressive performance of the first frame part and the second frame part through the reinforcing ribs.

[0021] Furthermore, a perforation is provided at the bottom of the second frame.

[0022] It is beneficial to increase the practicality of the key protection case through the perforation and the perforation is provided at the bottom so as not to damage the compressive performance of the key protection case.

[0023] Furthermore, the protective layer is a sealed layer with an open bottom.

[0024] It is beneficial to form a sealed cavity with the frame bracket through the sealed protective layer to extend the service life of the key protection case.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows: the frame bracket connected movably can not only strengthen the structural stability of the key protection case, but also improve the convenience of installation and disassembly of the frame bracket; the problem of improving the feel of the existing square frame bracket through the sharp corner part, strengthening the anti-slip performance through the protective layer; forming a larger space through the cavity to place the electronic module of the car key.

[0032] As Figures 1-3 shown, this embodiment provides an automobile key protection shell, which includes a frame bracket 10 and a protective layer 20. The frame bracket 10 includes a first frame 100 and a second frame 200 that are movably connected. The width between the first frame 100 and the second frame 200 gradually decreases from bottom to top along the long axis direction and forms a pointed corner portion. The width between the first frame 100 and the second frame 200 gradually increases from top to bottom along the long axis direction and forms a bottom; the protective layer 20 wraps around the outside of the frame bracket 10 to form a cavity.

[0033] In this embodiment, the frame bracket 10 is a metal frame, which is used to provide a deformation-resistant supporting force for the key protection shell. The edges of the frame bracket 10 are all smooth, which is convenient for improving the hand feeling when holding. The frame bracket 10 includes a first frame 100 and a second frame 200 that can form an opening and closing angle. The first frame 100 is in an L shape, and the second frame 200 is in a C shape. When the first frame 100 and the second frame 200 are not opened, they form a quadrilateral with a narrow top and a wide bottom, and a pointed corner portion is formed above, which is convenient for better exerting force when holding and further improves the hand feeling when holding. The protective layer 20 is a silica gel layer, which is used to prevent the key protection shell from falling. The protective layer 20 completely fits the edge shape of the frame bracket 10 and forms a cavity with the frame bracket 10, so that the electronic module in the key protection shell can be placed therein. An unlocking key, a locking car key, a trunk opening key, and a car finding key are sequentially arranged on the protective layer 20 from top to bottom. Ribs are provided between each key to distinguish them, so that the user can still accurately press the indicating patterns on the protective layer 20 when the vision is poor.

[0034] The frame bracket 10 further includes a clamping member 300 provided at the bottom. The pointed corner portion includes a rotating shaft 400. The first frame 100 and the second frame 200 rotate horizontally around the rotating shaft 400 and form an open or closed state with the clamping member 300. The connection line between the rotating shaft 400 and the clamping member 300 is inside the cavity.

[0035] In this embodiment, the horizontal rotation of the first frame 100 and the second frame 200 around the rotating shaft 400 enables the frame bracket 10 to be flexibly disassembled and installed.
