Description

Elastic key and electrical equipment

Technical Field

The utility model relates to the technical field of switch keys, in particular to an elastic key and electrical equipment.

Background

The patent document with publication number CN217061837U discloses an electrical switch key as shown in fig. 1, which comprises a switch key 3 and a key elastic arm 5, when the switch key 3 is pressed down, the key elastic arm 5 is pressed to deform and generate a certain elastic restoring force, and when the switch key 3 is released, the key elastic arm 5 is restored to deform, so that the switch key 3 can be driven to complete resetting.

The conventional key elastic arm is generally as shown in fig. 1, and has a flat plate structure, which has the following problems:

(1) although the spring-back mechanism has a certain spring-back effect, the spring-back force provided by the spring-back mechanism is smaller, and the spring-back speed is low; too small resilience force can not only influence the pressing hand feeling, but also easily cause the switch key 3 to form resonance with an electronic switch on the circuit board, so that vibration sound is caused;

(2) the elastic deformation stroke is smaller, and the requirement of a larger pressing stroke cannot be met.

Therefore, an improvement on the existing switch key of the electrical appliance is needed to solve the problem that the rebound force and the elastic deformation stroke are smaller.

The above information disclosed in this background section is only included to enhance understanding of the background of the disclosure and therefore may contain information that does not form the prior art that is presently known to those of ordinary skill in the art.
