A button device and electronic equipment

Abstract

Provided is a push-button apparatus, comprising a press assembly (10), a push-button base (20), and an elastic return member (30); the press assembly (10) comprises a push-button cap (11) and a sliding member (12), fixed opposite to each other; the push-button base (20) comprises a main body (21) having a projection, and a protrusion (22) provided with a track groove (23) on the main body (21); the elastic return member (30) is arranged around the outer surface of the protrusion (22) and its two ends elastically abut against the push-button cap (11) and the main body (21), respectively; the track groove (23) at least comprises a first locking position (01) and a second locking position (02); during the process of pressing of the push-button cap (11), the sliding member (12) slides in the track groove (23) and achieves a lock of the first locking position (01) and the second locking position (02). The push-button apparatus comprises only a press assembly (10), a push-button base (20), and an elastic return member (30); the sliding member (12) is relatively fixed on the press assembly (10), and the track groove (23) is provided on the push-button base (20) to allow the sliding member (12) to slide, pushing downward on the press assembly (10) to change the press state of the push-button apparatus; there are few structural members, reliability is high, and service life is longer.

Description

technical field [0001] The invention relates to a button structure, in particular to a button device and electronic equipment. Background technique [0002] The button structure can be applied to various mechanical and electronic devices. At present, the most common buttons include the button body and the shrapnel, but the button generally needs to be pressed frequently. This kind of button has a short service life and needs to be replaced frequently. The button structure is too restrictive. [0003] The Chinese patent with the application number 201410007007.6 discloses a button switch, which is composed of a main body 30' with a fixed contact, a rotor 40', a movable contact 50', a knob 60, a coil spring 70, and a cover 80'. The upper surface of the rotor 40' is formed with a concave-convex part 46, and the convex part 88 on the cover 80' is in sliding contact with the concave-convex part 46. During the reset action of the knob 60 by the elastic restoring force of the coil...
