[0025] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] See also Figure 1 、 Figure 2 and Figure 3 , this embodiment provides a mobile phone case button, which can be detachably installed on the mobile phone case. The mobile phone case button includes a button body 1, an extension body 2 and a PCBA board 3. The button body 1 has a pressing cavity 10, and a card slot 11 is formed on the outer edge of the button body 1. The lower side edge of the card slot 11 extends outward along the width direction to form a pressing edge 12. The extension body 2 is elastic. Part of the extension body 2 is movably arranged in the pressing cavity 10, and the bottom edge of the extension body 2 extends outward along the width direction to form an extension edge 20 that contacts the pressing edge 12. A glass plate 4 with an end surface exposed to the outside of the button body 1 is attached to the extension body 2 at one end away from the extension edge 20. The PCBA board 3 is inserted into the extension body 2. Pressing the glass plate 4 pushes the PCBA board 3 to touch the button of the mobile phone.

[0027] When installing the button, install the button on the corresponding mounting opening of the mobile phone case so that the side wall of the mounting opening is inserted into the card slot 11. The card slot 11 clamps the side wall of the mounting opening. The button is installed in the mobile phone case. The upper end surface of the button is flush with the outer wall of the mobile phone case or slightly higher than the outer wall. In order to ensure the beauty of the button when installed on the mobile phone case, and at the same time, the button can be mounted on the mobile phone case in a snap-in manner, the width of the upper side of the card slot 11 is smaller than the width of the lower side of the card slot 11. The upper side of the card slot 11 is set to the short side, which can avoid the problem of the button being too large when viewed from the mobile phone case. The upper surface of the exposed part of the glass plate 4 is flush with the upper end surface of the button body 1, ensuring the beauty of the mobile phone case while clamping the side wall of the mounting opening.

[0028] In addition, after the button is installed in the mobile phone case, when the mobile phone is installed, there is a certain distance between the bottom end surface of the PCBA board 3 and the button of the mobile phone, and the distance range is between 20-50 silks. That is to say, the bottom surface of the button is not flush with the inner wall of the mobile phone case, so that the PCBA board 3 on the button and the button of the mobile phone have a certain distance, and the thickness of the button body 1 is set according to needs, which can be adapted to mobile phone cases of different thicknesses. By setting this spacing, the button can better fit the button of the mobile phone, so that the adaptability of the button and the real machine can be achieved with 0 jamming and 0 delay, bringing a better experience to the user and a smoother operation experience through the mobile phone case button.

[0029] In order to enable the extension body 2 to move in the pressing cavity 10 when the glass plate 4 is pressed, and to prevent the extension body 2 from separating from the case body when it moves, an extension groove 21 is provided between the extension edge 20 and the side wall of the extension body 2. There are two extension grooves 21, which are respectively provided on the two long extension edges 20, and the extension grooves 21 extend along the length direction of the extension edge 20. The extension edge 20 located outside the extension groove 21 is adhered to the bottom surface of the pressing edge 12. That is to say, an extension groove 21 is provided on each side of the extension body 2. When the glass plate 4 is pressed to push the PCBA board 3, the extension groove 21 located in the pressing cavity 10 is moved. The body 2 shrinks and stretches downward, and the extension body 2 can be extended to a length of 6mm-10mm. At the same time, the extension edge 20 will be pulled. Since an extension groove 21 is provided, only part of the extension edge 20 is pulled, and the extension edge 20 adhered to the bottom surface of the pressing edge 12 will not be pulled, thereby preventing the extension body 2 from separating from the key body 1, effectively ensuring the service life of the key, and avoiding the problem of key deformation. It should be noted that the extension length is only the length designed in this embodiment. In other embodiments, the extension length can be less than 6mm or greater than 10mm. The extension length of the extension body 2 is designed according to needs.

[0030] In an optional embodiment, adhesive glue is applied to the extension body 2 in contact with the glass plate 4, and the adhesive glue forms an adhesive layer. The glass plate 4 is adhered to the extension body 2 through the adhesive layer. The thickness of the adhesive layer can be used to control the flushness of the upper end surface of the glass plate 4 and the upper end surface of the key body 1. In other embodiments, the height of the extension body 2 can also be set according to the height of the pressing cavity 10 to control the flushness of the upper end surface of the glass plate 4 and the upper end surface of the key body 1. The above method of controlling the flushness of the upper end surface of the glass plate 4 and the upper end surface of the key body 1 is not the only one, and will not be repeated here.

[0031] In order to be able to install the PCBA board 3 on the extension body 2, a mounting groove 22 is provided on the extension body 2 located in the push cavity 10, and the PCBA board 3 is partially installed in the mounting groove 22. The PCBA board 3 is fixedly connected to the side wall of the mounting groove 22 by gluing. In other words, a mounting groove 22 that can accommodate the PCBA board 3 is opened on the main body of the extension body 2, and then the PCBA board 3 and the extension body 2 can be inserted into the push cavity 10. When the glass plate 4 is pushed, the PCBA board 3 can be pushed to move, so that the PCBA board 3 contacts the buttons of the mobile phone and presses the buttons of the mobile phone. In order to prevent the PCBA board 3 from falling out of the mounting groove 22, in this embodiment, the PCBA board 3 is fixed in the mounting groove 22 by applying adhesive glue.

[0032] In the process of pressing the glass plate 4 to push the PCBA board 3, the extension body 2 will shrink and stretch. In order to prevent the extension body 2 from excessively squeezing the PCBA board 3 and prevent the PCBA board 3 from being deformed due to long-term use, a transition groove 23 is provided on the upper side wall of the installation groove 22. When the glass plate 4 is pressed to push the PCBA board 3, the extension body 2 is deformed and part of its area is compressed in the transition groove 23, thereby reducing the squeezing of the PCBA board 3 by the extension body 2. At the same time, since the extension body 2 is elastic, the PCBA board 3 is further protected, the deformation of the PCBA board 3 is prevented, and the service life of the key is ensured.

[0033] In an optional embodiment, the button body 1 is made of metal material, such as aluminum alloy, stainless steel, copper and the like, and is made by die-casting or casting process, and the button body 1 is electroplated so that the button body 1 has an electroplating layer, thereby reducing the static electricity generated by the button body 1. The metal button body 1 is used as a frame to enhance the texture of the mobile phone case.

[0034] In an optional embodiment, the extension body 2 is elastic. Therefore, the extension body 2 is made of soft silicone material. Soft silicone is free of harmful substances, soft, highly efficient, highly insulating, highly flame-resistant, resistant to high and low temperatures, highly compressible, and non-oxidizing. Therefore, the extension body 2 has excellent wear resistance and aging resistance, extending its service life. In some embodiments, the extension body 2 can be made of rubber or other elastic materials.

[0035] In summary, the key body 1 of the present invention is made of metal, a card slot 11 is formed on the outer edge of the key body 1, and the lower side edge of the card slot 11 extends outward along the width direction to form a pressing edge 12, the upper side width of the card slot 11 is smaller than the lower side width of the card slot 11, through this arrangement, the key adopts a card-in installation method, the installation is more flexible, simple, stable and reliable, an extension body 2 that can move in the press cavity 10 is provided on the key body 1, and the extension body 2 extends outward along the width direction to form an extension edge 20 that contacts the pressing edge 12, and the extension edge 20 located on the outside of the extension groove 21 is in contact with the pressing edge 12, and the press-type setting is provided. The stretchable extension body 2 can prevent the key from being deformed during long-term use, thereby ensuring the service life of the key, and a glass plate 4 with its end face exposed to the outside of the key body 1 is attached to the extension body 2 at one end away from the extension edge 20. Using the glass plate 4 as the contact surface can avoid the problem of key protrusion and breakage caused by long-term use, and prevent the problem of key wear; the extension body 2 is made of soft silicone material, which has excellent wear resistance and aging resistance, and extends the service life. The metal key body 1 is used as a frame to enhance the texture, and the contact surface made of glass material effectively restores the feel of the bare machine and improves the user's feel.
