[0032] like Figures 1 to 4 As shown, in one embodiment, an integrated waterproof keyboard of the utility model includes a body 1, a keyboard circuit 2 disposed in the body 1, and a plurality of keys 3 disposed on the top surface of the body 1;

[0033] The body 1 includes a metal bottom plate 11, a silicone liner 12, and a metal panel 13 stacked from bottom to top. A plurality of fasteners 14 are arranged around the body 1. The fasteners 14 penetrate the silicone liner 12 upward from the metal bottom plate 11 and are connected to the metal panel 13. The metal bottom plate 11 and the metal panel 13 clamp the silicone liner 12 toward each other through the fasteners 14, so that the silicone liner 12 can be tightly fitted between the metal bottom plate 11 and the metal panel 13 at least around one circle to form a sealed fit.

[0034] The keyboard circuit 2 is disposed between the metal bottom plate 11 and the silicone lining 12. The top surface of the silicone lining 12 is formed with an elastic key sheath 121 corresponding to each key 3. The elastic key sheath 121 will trigger the keyboard circuit 2 when it is pressed.

[0035] The key 3 includes a key cap 31 embedded in the corresponding elastic key sheath 121, and a folded edge 32 formed around the outer edge of the bottom of the key cap 31;

[0036] The metal panel 13 is provided with key openings 131 corresponding to the keys 3 . The key caps 31 of the keys 3 are inserted into the corresponding key openings 131 from the bottom of the metal panel 13 . The edges of the key openings 131 just block the folded edges 32 of the keys 3 .

[0037] In the above embodiment, since the edge of the key opening 131 just blocks the folded edge 32 of the key 3, in the assembled product, the key 3 will be restricted on the metal panel 13 by the key opening 131. Without removing the metal panel 13, the key 3 cannot be removed from the keyboard body 1, thereby achieving an anti-pry effect.

[0038] In the above embodiment, since the main body 1 includes the metal bottom plate 11, the silicone lining 12, and the metal panel 13 stacked from bottom to top, it has good explosion-proof and shock-proof effects.

[0039] In the above embodiment, the silicone lining 12 can at least be tightly fitted around the metal base plate 11 and the metal panel 13 to form a sealed fit, and the keyboard circuit 2 is arranged between the metal base plate 11 and the silicone lining 12, so the product is sealed as a whole, and has good resistance to gas and liquid intrusion, and can completely achieve a full surface waterproof function, and can therefore work normally in special environments such as moisture, mold, industrial oil pollution, chemical corrosion, etc.

[0040] like Figure 4 As shown, preferably, the fastener 14 is a screw, the metal base plate 11 is provided with a first through hole 111 for the screw to pass through, the silicone liner 12 is provided with a second through hole 122 for the screw to pass through, and the bottom surface of the metal panel 13 is provided with a screw sleeve 132 for the screw to be threaded.

[0041] Furthermore, the threaded sleeve 132 is embedded in the second through hole 122 , and this arrangement is mainly for facilitating assembly and positioning.

[0042] like Figure 5 As shown, compared with the above-mentioned embodiment, the present invention can adopt the technical solution of the following embodiment, that is, the metal bottom plate 11 has a mounting platform 112 wider than the periphery of the metal panel 13, and the mounting platform 112 is provided with a plurality of mounting holes 113 surrounding the metal bottom plate 11. This arrangement facilitates the use of bolts to penetrate the mounting holes 113, thereby fixing the keyboard body 1 on the table surface, so as to prevent the keyboard from accidentally sliding during use.

[0043] Furthermore, the silicone lining 12 has a skirt 123 that is wider than the periphery of the metal panel 13, the skirt 123 covers the mounting platform 112, and the skirt 123 is provided with avoidance holes 124 that are aligned with the mounting holes 113. The skirt 123 can act as an anti-slip gasket for bolt connection and protect the surface of the mounting platform 112 from being bumped and scratched.

[0044] like Figure 6 As shown, in Figure 5 On the basis of the embodiment shown, the skirt 123 also extends to the bottom surface of the mounting platform 112, thereby forming an edge structure around the mounting platform 112, thereby further enhancing the anti-collision protection effect of the product. When the keyboard body 1 is fixed on the table, the edge structure can also form a waterproof ring at the bottom of the keyboard body 1.

[0045] In addition, in a preferred embodiment, the metal base plate 11 and the metal panel 13 are aluminum alloy plates, which have strong anti-interference properties and can still work normally even in an environment with strong electromagnetic interference; and the key 3 is a plastic injection molded part, and the key 3 interface can be printed on the surface of the key 3 in the languages ​​of multiple countries.

[0046] For those skilled in the art, the protection scope of the present invention is not limited to the details of the above-mentioned exemplary embodiments. Without departing from the spirit or basic characteristics of the present invention, the equivalent meanings and all changes in the protection scope made by those skilled in the art based on the requirements of the present invention should be included in the present invention.
