Description

Technical Field

[0001] The utility model relates to the technical field of key protection, in particular to a key protection cover that utilizes elastic deformation of a material to realize a hovering function. Background Art

[0002] At present, there are many control buttons on the instrument panel. Installing protective covers on the buttons can prevent operators from accidentally operating the buttons and causing unnecessary consequences. In order to facilitate button operation, the protective cover is designed to hover (hovering is defined as a state in which an object maintains a basically unchanged spatial position), that is, the button protective cover hovers in two states, closed and open. In the closed state, the protective cover is closed and the buttons cannot be touched, thus protecting the buttons; in the open state, the protective cover is opened to a certain angle, and the buttons can be operated. By applying a small force to the protective cover, it is possible to switch between the two states, thereby realizing the hovering function of the protective cover.

[0003] Conventional key protection covers control the opening angle of the protection cover through the friction of the rotating shaft. They do not have the automatic opening and closing function. In a vibrating environment, the protection cover will automatically open and cannot prevent misoperation. Therefore, a key protection cover that uses the elastic deformation of the material to achieve a hovering function is proposed. Utility Model Content

The instrument panel is provided with buttons, and the base just surrounds the buttons. The base is rotatably connected to the protective cover, and an elastic deformation plate is provided at the rotating connection between the base and the protective cover for causing the protective cover to hover.

[0007] Preferably, the protective cover is connected to a top block, a rotating shaft is provided on the top block, and two symmetrically distributed rotating seats are connected to the base, and both ends of the rotating shaft are rotatably connected to the two rotating seats respectively.

[0008] Preferably, the elastic deformation plate is mounted on the base and located between the two rotating seats.

[0009] Preferably, two symmetrical mounting holes are provided on the base, and a screw is provided in each of the mounting holes for fixing the base on the instrument panel.

[0012] The utility model has a simple structure and good ergonomics. In actual use, the protective cover can be placed in two hovering states, open and closed, by rotating the protective cover at a certain angle. The hovering state will not change due to vibration, thereby improving the flexibility and reliability of the product, having a wide range of applications and good application prospects.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-7As shown, a button protective cover that uses elastic deformation of the material to achieve a hovering function includes an instrument panel 1 and a base 3 installed on the instrument panel 1, the instrument panel 1 is provided with a button 2, the base 3 just surrounds the button 2, and the base 3 is rotatably connected to the protective cover 4, and an elastic deformation plate 8 is provided at the rotating connection between the base 3 and the protective cover 4 for making the protective cover 4 hover.

[0023] In this embodiment, the protective cover 4 is connected to a top block 5, a rotating shaft 6 is provided on the top block 5, and two symmetrically distributed rotating seats 7 are connected to the base 3, and both ends of the rotating shaft 6 are rotatably connected to the two rotating seats 7 respectively.

[0024] In this embodiment, the elastic deformation plate 8 is installed on the base 3 and is located between the two rotating seats 7. There are two process gaps between the elastic deformation plate 8 and the two rotating seats 7, which increase the elastic deformation ability of the elastic deformation strip, thereby facilitating the interaction with the stop surface of the protective cover 4 to achieve the hovering function.

[0025] In this embodiment, two symmetrical mounting holes 9 are provided on the base 3 , and a screw 10 is provided in each mounting hole 9 for fixing the base 3 on the instrument panel 1 .

[0026] In this embodiment, the protective cover 4 is made of transparent plastic, and the characters on the key 2 can be clearly seen when the protective cover 4 is closed.

[0027] Working process and principle:

[0028] When in use, the base 3 is fixed to the instrument panel 1 by screws 10. When the protective cover 4 is opened, the stop surface 2 52 on the top block 5 is in contact with the elastic deformation plate 8, and the instrument panel 1 is in an open hovering state (such as Figure 5 As shown), when the protective cover 4 needs to be closed, a small force is applied to the protective cover 4 to rotate the protective cover 4 around the axis, and the top block 5 acts on the elastic deformation plate 8, causing the elastic deformation plate 8 to bend (as shown). Figure 6 As shown), the protective cover 4 continues to rotate around the axis, the deformation force on the elastic deformation plate 8 is released, and finally becomes a vertical state, the stop surface 51 of the top block 5 fits with the elastic deformation plate 8, and the protective cover 4 automatically closes to achieve a closed hovering state (as shown). Figure 7 shown).

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
