Embodiment Construction

[0013] Figure 1 to Figure 3 The button 1 of the present invention is shown schematically. The button 1 can be applied to any portable electronic device (not shown), such as personal digital assistants, mobile phones, and notebook computers. It can be understood that the electronic device may include a plurality of keys 1 , and in order to simplify the illustration, only one key 1 is schematically drawn in the figure. The shape of the button 1 can also be changed according to actual needs, and is not limited to the circle shown in the figure.

[0014] The button 1 includes a cover 10 , a button 11 , a washer 12 , a coil spring 13 and a trigger switch 14 . Wherein, the cover 10 is fixed on the inner wall of the housing 2 of the electronic device through a first adhesive layer 15 (such as PSA, pressure-sensitive adhesive), and the button 11, the gasket 12 and the coil spring 13 are all accommodated in the cover. 10 , the trigger switch 14 is disposed under the cover 10 . The...

Abstract

An exemplary button assembly for use in an electronic device includes a casing, a switch, a button, a spacer, and a coil spring. The casing is connected to the electronic device. The switch is arranged under the casing. The button is received in the casing. The spacer is received in the casing and arranged between the button and the coil spring. The spacer is attached to the button and configured to actuate the switch when the button is pressed. The coil spring is received in the casing and arranged between the button and the casing. A diameter of the coil spring approximately equals that of the flange of the button, thereby providing an elastic force towards a keystroke axis of the button when the button is released, and the elastic force improves stability of the button while the button is returning to its original position.

Description

technical field [0001] The invention relates to a key, in particular to a key applicable to portable electronic equipment. Background technique [0002] Generally speaking, the panels of portable electronic devices such as personal digital assistants, mobile phones and notebook computers are often provided with buttons for controlling power switches or other function adjustments. With the rapid development of the electronic industry, the requirements for the control accuracy of the keys in the electronic equipment are also getting higher and higher. The trigger part of the key switch in the traditional key is generally an arched shrapnel, which is used to push the key to make it reset when the deformation is restored. However, if the elastic restoring force provided by the arched shrapnel deviates from the key travel direction of the key, it may prevent the key from being bounced, resulting in a key stuck phenomenon. Contents of the invention [0003] In view of this, it...
