Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switches, in particular to a switch assembly that can prevent shaking. Background Art
[0002] At present, electronic products on the market (such as televisions, speakers, air conditioners, etc.) are all provided with corresponding switch assemblies to control different working states of the electronic products; and these switch assemblies usually have various types, such as a switch assembly with only a rotation function, a retractable switch assembly, a switch assembly with rotation and pressing functions, etc.
[0003] Such a switch assembly generally includes an encoder, a knob, a button, etc. The encoder converts angular displacement or linear displacement into an electrical signal, and the rotation and pressing functions of the encoder can be realized through a handle rod. To achieve the rotation and pressing functions, there needs to be a clearance reserved between the handle rod and the encoder, which results in problems of axial clearance and swing in the axial rotation direction of the handle rod itself. The swing angle of a commonly used encoder in the axial rotation direction is below 5°. Due to the swing angle in the axial rotation direction of the encoder, when a knob is directly sleeved outside the handle rod and the handle rod is rotated by the knob to drive the encoder to move, the swing amount of the knob will be amplified and cause shaking, giving the user the feeling that the knob is not firmly fixed and is loose, seriously affecting the user experience of the knob.
[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Utility Model
