Translational key with guide function

Abstract

The invention is concerned with the translation key equipment with guiding function, includes the key, the positioning seat, the press bar and the electrical conductor switch, the key is with key cap including at least one guiding outfit that effects on the key cap and the positioning seat, the guiding outfit consists of the guiding column and the guiding slot that cooperates with the guiding column closely; the guiding column fixes on the key cap or the positioning seat, the guiding slot fixes on the other one. it is: presses downward by using any part of the key as the point, the guiding column clings on the surface of the guiding slot and move balance and smoothly, in order to limit the key cap can not be excursion and turn up.

Description

technical field [0001] The invention relates to a key device, in particular to a translational key device with a guiding function, which is suitable for large keys used in car audio systems. Background technique [0002] The structure of the existing function button device used in car audio generally includes: [0003] 1. As shown in Fig. 1 single pressure bar type key: the key 1 includes a key cap 11 and cap edge 42, a pressure bar 14, a positioning seat 2, a luminous body 5 and a conductor switch 4. The defect of this device is that it is only suitable for small function keys, and because the design of the device pressure bar 14 and conductor switch 4 occupies the position of the illuminant at the central part of the button keycap, it affects the uniform lighting effect of the illuminant. And because the pressure rod 14 and the conductor switch 4 of this device are designed in the central part of the key cap, when the edge of the key cap 11 is pressed, it is easy to warp ...

AI Technical Summary

Problems solved by technology

The defect of this device is that two pressure rods 14 are used, and when the edge of the key cap 11 is pressed, it is easy to tilt up and fail to achieve the effect of a balanced action.

And adopt two conductor switch 4, increase cost does not conform to economic benefit

[0005] 3. As shown in Figure 1 and Figure 2: the button cap edge 42 and the positioning seat 2 are in four-sided contact and braking limit. Loud friction sound, affecting car audio listening effect
