a waterproof knob

Abstract

The invention relates to a waterproof knob. The waterproof knob type includes a knob assembly, a panel for installing the knob assembly, and a hollow encoder matched with the knob assembly. The first water surrounding wall, the second water surrounding wall and the third water surrounding wall are respectively formed on the ring, the knob decoration ring and the panel, which are close to the positions of the first water surrounding wall, the second water surrounding wall and the third water surrounding wall The first drainage hole, the second drainage hole and the third drainage groove are respectively formed; the external moisture enters the outside of the first water surrounding wall and flows to the outside of the second water surrounding wall through the first water drainage hole, and then passes through the second water drainage The hole flows to the outside of the third wall, and finally flows out to the outside of the panel through the third drainage groove. The waterproof knob of the invention has the advantages of simple structure, novel design, low cost, very good waterproof effect, and effectively protects electrical functions.

Description

technical field [0001] The invention relates to a knob of a vehicle-mounted central control instrument panel, in particular to a waterproof knob with a waterproof structure. Background technique [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 ente...
