Description

Technical Field

[0001] The utility model relates to the field of electronic products, and particularly relates to a waterproof remote controller. Background Art

[0002] A remote controller is an electronic device used to remotely control another device or system. Through modern digital coding technology, the key information is encoded, and light waves are emitted through an infrared diode. The infrared receiver of the receiver converts the received infrared signal into an electrical signal, which is then decoded by the processor to demodulate the corresponding instructions to achieve the required operation requirements for controlling the device or system.

[0003] In order to balance the pressing feel, the existing remote controllers usually adopt silicone keys. And in order to facilitate the installation of the silicone keys, there is usually a gap between the remote controller housing and the silicone keys. When the remote controller is splashed with liquid, the liquid will enter the remote controller along the gap, and the flowing-in liquid is likely to cause a short circuit of the internal integrated circuit board, seriously affecting the service life of the remote controller. Therefore, the utility model proposes a waterproof remote controller. Summary of the Invention

[0004] The utility model provides a waterproof remote controller to solve the problems mentioned in the above background art.

[0005] The purpose of the utility model is achieved in the following way:

[0006] A waterproof remote controller includes a housing, an integrated circuit board, and a waterproof pad. A plurality of keys that can pass through the housing are arranged on the waterproof pad. The waterproof pad is installed at the upper end of the integrated circuit board. An upwardly protruding waterproof wall is arranged at the outer edge of the waterproof pad, so as to form a sealed cavity between the waterproof pad and the housing. Drainage ports that are communicated with the outside are arranged on both sides of the sealed cavity.

[0007] Further, a rib edge is arranged on the waterproof wall.

[0008] Further, a waterproof ring for fitting with the housing is arranged around the outside of the key.

[0009] Further, the middle of the waterproof pad bulges and both sides slope downwards.

[0010] Further, a sealing portion is arranged around the lower end of the waterproof pad.

[0011] Further, a convex structure is arranged on the sealing portion.

[0012] The present utility model increases a waterproof wall that protrudes upward on the waterproof pad, so as to form a sealed cavity between the waterproof pad and the housing. When liquid enters the remote control, the liquid can be isolated in the sealed cavity, preventing the liquid from contacting the integrated circuit board. Moreover, through the arrangement of drain ports on both sides, the liquid can be quickly discharged from the sealed cavity, thereby significantly improving the waterproof effect of the remote control and ensuring the service life of the remote control.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be further described in detail below in conjunction with the drawings and the detailed description of the embodiments.

[0018] In this embodiment, referring to Figures 1 - 3 , a waterproof splash remote control specifically implemented includes a housing, an integrated circuit board 4, and a waterproof pad 3. The housing includes an upper cover 1 and a base 2. The upper cover 1 is provided with a plurality of positioning holes 8. A plurality of buttons 7 integrally formed on the waterproof pad 3 can pass through the upper cover 1 and are received in the positioning holes 8, thereby realizing the positioning of the waterproof pad 3.

[0019] Furthermore, a waterproof pad 3 and an integrated circuit board 4 are provided between the upper cover 1 and the base 2. The integrated circuit board 4 is arranged at the lower end of the waterproof pad 3. A waterproof wall 5 that protrudes upward is provided at the edge of the waterproof pad 3, so as to form a sealed cavity 9 between the waterproof pad 3 and the housing. The liquid entering the remote control will temporarily stay in the sealed cavity 9, thereby preventing the splashed liquid from contacting the integrated circuit board 4.

[0020] Furthermore, the waterproof pad 3 is designed with a middle protrusion and downward slopes on both sides, so that the liquid entering the sealed cavity 9 will flow to the drain ports 10 on both sides of the waterproof pad 3, and the liquid is discharged through the drain ports 10 that penetrate to the outside of the housing. During the daily use of the remote control, the liquid in the sealed cavity 9 can also be quickly discharged by shaking or patting the remote control.

[0021] Furthermore, an edge 11 is provided on the waterproof wall 5. The edge 11 is in close fit with the upper cover 1 and is designed to extend outward, thereby preventing the liquid in the sealed cavity 9 from flowing back into the integrated circuit board 4 when the remote control is placed face down.

[0022] Furthermore, a waterproof ring 6 for fitting with the housing is provided around the outside of the button 7. The design of the waterproof ring 6 seals the gap between the button 7 and the upper cover 1, further enhancing the sealing performance of the remote control.

[0023] Furthermore, a sealing portion 12 is provided around the lower end of the waterproof pad 3. The integrated circuit board 4 is installed in the sealing portion 12. A convex structure 14 is provided on the sealing portion 12 to prevent liquid from flowing in through the housing joint, further improving the waterproof performance of the remote control.

[0024] Furthermore, a contact 13 is provided at the lower end of the button 7. When the button 7 is pressed, the contact 13 touches the integrated circuit board 4, thereby generating a signal. The signal is transmitted to the device or system through an infrared emitter provided at one end of the integrated circuit board 4 to achieve the purpose of remote control.

[0025] Furthermore, a battery compartment for accommodating a battery is provided on the base 2. The battery compartment is connected to the integrated circuit board 4, so that the battery can supply power to the integrated circuit board 4 after the battery is installed.

[0026] In the present utility model, by adding an upward convex waterproof wall 5 on the waterproof pad 3, a sealed cavity 9 is formed between the waterproof pad 3 and the housing. When liquid enters the remote control, the liquid can be isolated in the sealed cavity 9 to avoid contact between the liquid and the integrated circuit board 4. And through the arrangement of the two drainage ports 10, the liquid can be quickly discharged from the sealed cavity 9, thereby significantly improving the waterproof effect of the remote control and ensuring the service life of the remote control.

[0027] The above are only preferred embodiments of the present utility model and do not impose any form of limitation on the present utility model. Although the present utility model is disclosed above in preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the technical solution scope of the present utility model, when making some changes or modifications using the above-disclosed technical content into equivalent embodiments of equivalent changes, but as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical means of the present utility model shall fall within the scope of the technical solution of the present utility model.
