Description

Technical Field

[0001] The present invention relates to a control device on a vehicle control panel, and in particular, to a light guide combined knob structure. Background Art

[0002] With the development of modern transportation technology, current vehicles such as airplanes, cars, and ships have more and more functions, and driving operations are becoming more and more complex. Considering ergonomics, the requirement for function integration of control devices is getting higher and higher, and in a night vision environment, the requirement for visualization of control devices is getting higher and higher.

[0003] Currently, some manufacturers have designed a multi-functional integrated switch. This switch can achieve three functions through the inner shaft and the outer shaft of the switch. Among them, the inner shaft of the switch can achieve the function of a push switch by pressing. At the same time, the inner shaft of the switch can achieve the function of an optical encoder by rotating. The outer shaft of the switch can achieve the function of selecting the band position of a band switch by rotating. This multi-functional integrated switch highly integrates the three functions of a push switch, an optical encoder, and a band switch, which is very beneficial for reducing the operation space in the cockpit and reasonably dividing the functional areas.

[0004] However, for the above multi-functional integrated switch, there is no supporting dedicated knob assembly yet. Summary of the Invention
