Steering wheel touch switch structure

Abstract

The invention discloses a steering wheel touch switch structure which comprises a control circuit board, a touch panel, a touch detection device and a pressure detection device which are arranged on aswitch shell, and the touch detection device is arranged on the inner bottom surface of the touch panel. The pressure detection device comprises a pressure sensing part arranged on the control circuit board, and a driving rod correspondingly arranged on the inner bottom surface of the touch panel and is connected with the pressure sensing part. By using the technical scheme, only when the touch detection device and the pressure detection device are triggered together, the control circuit board can confirm that the touch function is effective, and mistaken touch phenomenon can be effectively prevented from occurring. The touch panel with the structural design does not generate pressing stroke amount when being stressed at any position, and is more compact in structure, the touch panel is prevented from shaking, the structural stability is good, the use hand feeling is better, the use performance of the steering wheel switch is improved.

Description

technical field [0001] The invention relates to the technical field of automobile switches, in particular to a steering wheel touch switch structure. Background technique [0002] With the continuous development and promotion of automobile technology, the steering wheel switch of the car gradually adopts touch switches. When the user touches the button characters on the steering wheel with his hand, the corresponding button function is triggered. Compared with the traditional mechanical switch, this push-type touch Steering wheel switches are more modernized and are replacement products of traditional mechanical push-button switches, as well as the development trend of the future switch field. [0003] In order to prevent the touch function of the steering wheel switch from being falsely triggered, the existing method is to press the switch as a whole to confirm that the touch function of the switch is turned on. To the touch panel, flexible PCB board, button seat, housing,...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the complex structure of the push-type touch steering wheel switch in the prior art, which is not conducive to the miniaturization of the switch, and the pressing stroke of the switch panel is large, and the amount of shaking is also large, which makes the user feel uncomfortable. Poor, which affects the use effect of the product, so as to provide a steering wheel touch switch structure with a simple and compact structure, no pressing stroke and shaking when pressing the touch panel, and improving the feel and performance of the product
