Embodiment Construction

[0013] The novel knob structure of the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0014] See figure 1 , a novel knob structure, which mainly includes a panel 10, a circuit board 60 fixed behind the panel 10 and a plurality of LED lights (not shown) evenly distributed on the front panel of the circuit board 60. A circular first opening 11 is formed on the panel 10 , and the first opening 11 is used to allow the top of the knob assembly to pass out to the outside.

[0015] Preferably, a knob assembly 20 , a knob bracket 30 , a potentiometer 40 and a silicone pad 50 are arranged in sequence between the bottom of the panel 10 and the circuit board 60 .

[0016] The top of the knob assembly 20 extends vertically upward from the first opening 11 to the outside of the panel 10 , and extends laterally along the edge of the rear of the knob assembly 20 to form a ring-shaped limit plate 21 , and the li...

Abstract

The invention relates to a novel knob structure. The novel knob structure comprises a panel and a circuit board, a knob assembly, a knob support, a potentiometer and a silica gel pad are further sequentially disposed between the bottom of the panel and the circuit board, and, structurally, an annular flange structure of the knob support is used to match an annular groove in the panel, so the knob assembly can be ensured to locate at the center of a first opening of the panel after installation, and then gap uniformity is guaranteed. After all parts are assembled together, a limit plate of the knob assembly is clamped between the panel and the knob support, and the larger the plane, the more stable the knob. The novel knob structure has the advantages of clever design and reasonable structure, and effectively improves product quality.

Description

technical field [0001] The invention relates to the technical field of in-vehicle entertainment systems, in particular to a novel knob structure. Background technique [0002] At present, there are generally two types of knob structures for in-vehicle entertainment systems: knobs that use a shaft-type potentiometer to rotate as a whole, and knobs that use the outer ring of a hollow potentiometer to rotate and press in the middle. Now the knob with hollow potentiometer has become the mainstream. The outer ring of this knob structure can be rotated, and the middle button part usually has a backlight to achieve multi-function integration. At present, the knob of the hollow potentiometer is positioned by the potentiometer itself, and the knob has obvious shaking and uneven gap problems. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a novel knob structure. [0004] The technical solution adopted by the present invention to solve the abov...
