[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-7 As shown, this utility model discloses a waterproof mounting structure for a remote control circuit board 20, which includes a lower shell 10 (a part of the remote control housing), a circuit board 20, a waterproof pad 30, and a pressure pad frame 40. The lower shell 10 has a one-way opening mounting cavity 11. A one-way opening tubular structure can be integrally formed in the lower shell 10. The inner cavity of the tubular structure is the mounting cavity 11, the end face of the tubular structure is the cavity opening 12 of the mounting cavity 11, and the outer wall of the tubular structure is the outer wall of the cavity opening 12 of the mounting cavity 11. The circuit board 20 is mounted in the mounting cavity 11 by screws. The waterproof pad 30 can completely cover the cavity opening 12 of the mounting cavity 11, thereby sealing the mounting cavity 11. The pressure pad frame 40 is detachably connected to the lower shell 10, for example, by screw connection or snap-fit, and the pressure pad frame 40 cooperates with the cavity opening 12 of the mounting cavity 11 to press the outer edge of the waterproof pad 30, thereby fixing the waterproof pad 30. The pressure pad frame 40 is hollow inside, so it will not interfere with the operation key 50 touching the control element 21 on the circuit board 20. Moreover, the waterproof pad 30 can also provide a certain cushioning effect and protect the control element 21. The waterproof pad 30 can be made of silicone or flexible rubber.

[0032] To ensure a waterproof seal between the edge of the waterproof gasket 30 and the opening 12 of the mounting cavity 11, this design requires the outer edge of the waterproof gasket 30 to be inserted into the opening 12 of the mounting cavity 11. As a preferred embodiment, a first sealing ring 31 and a second sealing ring 32 are provided on the outer edge of the waterproof gasket 30. The second sealing ring 32 is parallel to the first sealing ring 31 and is positioned within the first sealing ring 31. The inner ring of the first sealing ring 31 is fitted to the outer wall of the opening 12 of the mounting cavity 11, while the outer ring of the second sealing ring 32 is fitted to the mounting cavity 11. This creates a gap between the first sealing ring 31 and the second sealing ring 32 that fits into the opening 12 of the mounting cavity 11. This gap aligns with the opening 12 of the mounting cavity 11, facilitating the installation of the waterproof gasket 30 and ensuring a more precise installation position with less risk of displacement. To facilitate the installation of the waterproof gasket 30, the thickness of the first sealing ring 31 is required to be no less than the thickness of the second sealing ring 32.

[0033] Additionally, a baffle 41, adapted to the outer ring of the first sealing ring 31, is provided on the outer edge of the pressure pad frame 40. In this way, when the pressure pad frame 40 presses the waterproof gasket 30 against the opening 12 of the mounting cavity 11, the baffle 41 and the first sealing ring 31 are tightly fitted, the opening 12 of the mounting cavity 11 is inserted into the inner ring of the first sealing ring 31, and the second sealing ring 32 is inserted into the mounting cavity 11. The outer edges of the first sealing ring 31, the second sealing ring 32, and the waterproof gasket 30 are all tightly fitted with the opening 12 of the mounting cavity 11. Of course, it is also possible to omit the second sealing ring 32, or to omit both the first sealing ring 31 and the second sealing ring 32.

[0034] To facilitate the installation of the waterproof pad 30 and the pressure pad frame 40, a positioning post 13 is provided in the mounting cavity 11 to position and cooperate with the waterproof pad 30. The waterproof pad 30 is provided with a positioning hole 33 to cooperate with the positioning post 13, and the circuit board 20 is provided with a clearance hole to avoid the positioning post 13. A connecting post 14 is provided on the lower shell 10 to position and cooperate with the pressure pad frame 40. The pressure pad frame 40 is provided with a connecting hole 42 to cooperate with the connecting post 14, and the pressure pad frame 40 can be screwed to the connecting post 14.

[0035] Because the remote control will have several operation keys 50, the circuit board 20 needs to have control elements 21 corresponding to the operation keys 50. In order to prevent the operation keys 50 from causing excessive pulling on the waterproof pad 30, the waterproof pad 30 is provided with arched portions 34 that correspond one-to-one with the control elements 21. The control elements 21 are placed in the arched portions 34. In addition, the arched portions 34 can be thickened to a certain extent.

[0036] By placing the circuit board 20 in a one-way opening mounting cavity 11, with the cavity opening 12 of the mounting cavity 11 covered by a waterproof gasket 30, and the pressure pad frame 40 cooperating with the cavity opening 12 of the mounting cavity 11 to press the outer edge of the waterproof gasket 30, the mounting cavity 11 is sealed, thus ensuring the waterproof performance of the circuit board 20. Furthermore, the waterproof performance is excellent. When the remote control is disassembled, the connection between its upper or lower shell 10 will not interfere with the waterproof mounting structure, and the waterproof structure is not easily damaged. In addition, the installation of the waterproof gasket 30 is simple, and it can be easily restored after disassembly, resulting in high reliability. Moreover, the above design eliminates the need for sealant, providing convenience for production assembly or consumer self-assembly.

[0037] The circuit board 20 with the aforementioned waterproof structure can be waterproofed in two ways: First, a rechargeable battery is placed in the mounting cavity 11, and a waterproof charging interface is embedded in the lower shell 10, which connects to the rechargeable battery. Second, the lower shell 10 has a cover 17 and a one-way opening battery compartment 15. The cover 17 and the opening of the battery compartment 15 are sealed together by a sealing ring 16, and the cover 17 is screwed or snapped to the lower shell 10. The battery compartment 15 communicates with the mounting cavity 11. By filling the battery compartment 15 with batteries to power the circuit board 20, simply ensuring the cover 17 is closed is sufficient to ensure the waterproofing of the circuit board 20 and the battery. In this case, the latter is preferred, as the remote control can be used continuously simply by replacing the battery, without waiting for recharging.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
