Key structure

Abstract

The invention discloses a key structure, which to the field of electrical components and provides a simple key structure. The key structure comprises a key body, positioning devices, springback devices, key travel control devices, light guide devices and a key device, wherein the key body is divided into a key body edge part, a key body middle part and a key body core part according to the distance to the key body center; the outer side of the key body is provided with a display structure; the positioning devices are arranged on the inner side of the key body edge part, and each positioning device includes a positioning piece and a positioning hook; the springback devices are arranged on the inner side of the key body edge part, each springback device is in the shape of a long strip and has elasticity, and one end of the springback device is connected with the key body and obliquely extends inwards along the outer contour of the key body; the key travel control devices are arranged onthe inner side of the key body edge part, and each key travel control device is a limit column protruding out of the key body; the light guide devices are arranged on the key body middle part; and thekey device is arranged on the inner side of the key body core part.

Description

technical field [0001] The invention relates to the field of electrical components, in particular to a button structure. Background technique [0002] The physical buttons of the TV need to take into account the functions of physical positioning, rebound, buttons, button travel control and LOGO light guide. Among them, physical positioning refers to positioning the keys to avoid the keys from falling off or shifting. The existing keys are often installed on the circuit board through fasteners, and the keys rely on their own structure to achieve physical positioning; resulting in many key parts and complicated assembly. It is also more troublesome on the board. Rebound means that the button can bounce back after being pressed. The existing button is often implemented by using a spring, which makes the button thicker, which is not conducive to reducing the thickness of the TV. In addition, because the existing keys have many components for physical positioning, rebound, key ...

Problems solved by technology

Among them, physical positioning refers to positioning the keys to avoid the keys from falling off or shifting. The existing keys are often installed on the circuit board through fasteners, and the keys rely on their own structure to achieve physical positioning; resulting in many key parts and complicated assembly, and the keys are assembled into the circuit. It is also more troublesome on the board

Rebound means that the button can bounce back after being pressed. Existing buttons are often implemented with springs, which makes the button thicker, which is not conducive to reducing the thickness of the TV.

In addition, because the existing keys have many components for physical positioning, rebound, key and key travel control, which take up a lot of space, it is difficult to arrange the LOGO light guide structure or the light guide effect is not good.

Also due to the large number of components, reliability is often difficult to guarantee
