Problems solved by technology

[0002] The knobs commonly used in car audio systems are mostly designed on the instrument panel of the central control. The encoders in the knobs placed in these places can be shaft-type or hollow-type. Choose the appropriate encoder type according to your needs. Usually the knobs in these places often have relatively low requirements on the waterproof level; in order to facilitate the driver to drink water, some similar devices such as mineral water bottles are usually designed near the knobs. Therefore, in actual life, the water in the mineral water bottles will Sprinkling on the knob will cause the electrical function to fail and endanger driving safety. Therefore, the waterproof level of the knob must meet stricter requirements to effectively prevent external moisture from entering the car audio system through the knob

Embodiment Construction

[0019] The waterproof knob of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0020] See figure 1 and figure 2 , a waterproof knob, which includes a knob assembly 10, a panel 20 for installing the knob assembly 10, and a circuit board 40 arranged below the panel 20, wherein the panel 10 is formed with a mounting hole 23 for the knob assembly 10 to pass through , the upper part of the circuit board 40 is provided with a hollow encoder 30 coaxial with the mounting hole 23. It can be understood that a conductive silicone LED lamp and the like are also provided on the circuit board 40 corresponding to the position of the hollow encoder 30, because it is a commonly used technology, so I won't go into details here.

[0021] At present, many projects in the car factory require the knob to not only ensure sufficient torque, but also need to solve a small space. Therefore, this case adopts the knob...

Abstract

The present invention relates to a waterproof knob. The waterproof knob comprises a knob assembly, a panel for mounting the knob assembly, and a hollow encoder matched with the knob assembly to be installed. The knob assembly comprises a knob cap, a light guide ring, a knob ring, and a knob decoration ring, wherein the above parts are sequentially sleeved together. The knob ring, the knob decoration ring and the panel are respectively provided with a first water surrounding wall, a second water surrounding wall and a third water surrounding wall. A first water drainage hole, a second water drainage hole and a third water drainage groove are formed to be positioned close to the first water surrounding wall, the second water surrounding wall and the third water surrounding wall, respectively. The external water enters into the exterior of the first water surrounding wall and then flows into the exterior of the second water surrounding wall via the first water drainage hole. After that, the external water flows into the exterior of the third water surrounding wall via the second water drainage hole and finally flows out of the exterior of the panel via the third water drainage groove. According to the technical scheme of the invention, the waterproof knob is simple in structure, novel in design, low in cost and good in waterproof effect. By means of the waterproof knob, electrical equipment can be effectively protected.
