[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In order to solve the above problems, this solution proposes a dual-control waterproof switch button 2, please refer to Figures 1 to 4, comprising an electric board 1, at least one button 2, a wire body 3 and an elastically deformable waterproof shell 4; the waterproof shell 4 comprises a waterproof button plate 40, a plurality of waterproof side plates 41 and a bottom plate 42, the waterproof side plates 41, the waterproof button plate 40 and the bottom plate 42 are integrally formed, and the bottom plate 42 is provided with an installation opening 420; along the direction from the waterproof button plate 40 to the installation opening 420, the button 2 and the electric board 1 are sequentially installed in the waterproof shell 4; the wire body 3 penetrates the waterproof Inside the shell 4, the wire body 3 is glue-sealed to the waterproof shell 4, and the wire body 3 is electrically connected to the electric board 1; the space enclosed by the electric board 1 and the installation opening 420 is coated with sealing glue to make the bottom surface of the electric board 1 waterproof and to seal the electric board 1 and the waterproof shell 4. When in use, pressing the deformable waterproof key panel 40 can make the key 2 contact with the electric board 1, so that the local circuit of the electric board 1 is connected, and then the switches of other components are controlled through the wire body 3.

[0029] After adopting this setting method, on the one hand, the button 2 and the electric board 1 are sealed and installed in the waterproof shell 4 through the integrated waterproof shell 4 and the sealing glue at the installation opening 420, thereby avoiding the situation where there is a gap between the shell and the button 2, and at the same time avoiding the possibility of a gap on the installation opening 420. On the other hand, since the wire body 3 and the installation opening 420 are sealed with glue, the button 2 and the electric board 1 are completely sealed in the waterproof shell 4, and a waterproof and sealed connection between the button 2 and the shell is effectively achieved.

[0030] Regarding the above-mentioned waterproof housing 4, as Figures 1 to 4 As shown, the waterproof shell 4 is preferably made of silicone material. Silicone has good deformability and waterproofness and can be integrally formed. It is the preferred material for this solution. Of course, other waterproof sealing materials that can be integrally formed can be selected by technical personnel in this field according to their actual needs.

[0031] like Figure 4 As shown, in order to enhance the sealing and waterproof effect of the waterproof shell 4, the waterproof shell 4 is provided with a wire accommodating groove 421, and the wire accommodating groove 421 is provided on the bottom plate 42; the wire accommodating groove 421 passes through the waterproof side plate 41 and the bottom plate 42, the wire accommodating groove 421 is communicated with the installation opening 420, and the wire body 3 is installed in the wire accommodating groove 421; the space enclosed by the wire accommodating groove 421, the electric board 1, the installation opening 420 and the wire body 3 is coated with sealing glue. After adopting this setting method, the wire body 3 in the wire accommodating groove 421 and the waterproof shell 4, and the electric board 1 and the installation opening 420 are completely sealed by the sealing glue, thereby enhancing the sealing and waterproof effect of the waterproof shell 4.

[0032] like Figure 4 As shown, in order to prevent the electric board 1 from moving up and down in the waterproof shell 4, an electric board mounting groove 410 is provided on the inner wall of the waterproof shell 4, that is, an electric board mounting groove 410 is provided on the inner wall of the waterproof side plate 41, and the electric board 1 is installed in the electric board mounting groove 410. After adopting this setting method, the electric board 1 can be stably installed in the electric board mounting groove 410.

[0033] Further, such as Figure 4 As shown, in order to better fix the electric board 1, the electric board mounting groove 410 is arranged around the inner wall of the waterproof shell 4. After adopting this arrangement, the electric board 1 is installed in the electric board mounting groove 410 around a circle, which helps to fix the electric board 1 therein.

[0034] Furthermore, Figure 4 As shown, in order to facilitate the connection between the wire body 3 and the electrical board 1, the electrical board mounting groove 410 is connected with the wire accommodating groove 421, that is, one side wall of the electrical board mounting groove 410 is through-connected, and the wall is the surface close to the side of the wire accommodating groove 421, so that the electrical board mounting groove 410 is connected with the wire accommodating groove 421.

[0035] like Figure 1 and Figure 3 As shown, regarding the above-mentioned keys 2, each key 2 includes a keycap 20 and a mounting cap frame 21; the mounting cap frame 21 is fixedly arranged on the electrical board 1, and the mounting cap frame 21 is provided with a mounting through-cap hole, and the through-cap hole is oriented toward the electrical board 1; the keycap 20 can be movably arranged in the mounting through-cap hole, and the keycap 20 can move along the axial direction of the mounting through-cap hole, and an elastic member is also provided between the keycap 20 and the electrical board 1. After adopting this arrangement, when an external force presses the keycap 20, the keycap 20 can move toward the electrical board 1 until it abuts, thereby making part of the circuit of the electrical board 1 connected.

[0036] Preferably, the number of buttons 2 is preferably two, so that dual control can be achieved when in use. Of course, the number of buttons 2 in this solution is a preferred embodiment, and those skilled in the art can select the number of buttons 2 according to actual needs.

Of course, other waterproof sealing materials or sealing glues that can be integrally formed can be selected by technical personnel in this field according to their actual needs.

[0041] As can be seen from the above, the basic structure and principle of this solution will be described below in conjunction with the specific assembly process.

[0042] During assembly, first snap the button 2 and the board 1 into the waterproof housing 4, then turn it over and pour the potting colloid into the space enclosed by the board 1 and the installation opening 420. After the colloid solidifies, it will adhere firmly to the silicone housing, so that water cannot enter the button 2 or the board 1, thereby achieving the waterproof effect of the button 2.

[0043] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
