Abstract

The invention relates to a key structure, in particular to a vehicle-mounted touch key structure and belongs to the technical field of automotive electronics. The technical scheme is that the vehicle-mounted touch key structure comprises a touch key body, wherein the touch key body comprises a touch tablet and a circuit board located under the touch tablet. The touch tablet is provided with a plurality of key regions, wherein the key regions correspond to wiring bonding pads under the circuit board, and the wiring bonding pads can sense voltage change values produced by touch pressure in the key regions. The touch key body comprises the touch tablet and the circuit board, the touch tablet is a glass tablet and adheres to the circuit board, the circuit board can receive voltage values produced by the pressure of related key regions on the touch tablet and convert the voltage values into digital signals so as to achieve control operation of a vehicle-mounted terminal. The vehicle-mounted touch key structure is compact, convenient to install and use, wide in application range, safe and reliable, and the using cost is reduced.

Description

Technical field [0001] The invention relates to a key structure, in particular to a vehicle-mounted touch key structure, belonging to the technical field of automobile electronics. Background technique [0002] Existing in-vehicle terminals generally use plastic buttons as a quick user operation method. For example, the realization of functions such as music playing and one-key talk. This type of button needs to be formed by a plastic mold, which is time-consuming and costly. Moreover, the keys protruding from the center console in the car after installation will pose a safety hazard. Summary of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a vehicle-mounted touch key structure, which has a compact structure, convenient installation and use, reduced use cost, wide application range, safety and reliability. [0004] According to the technical solution provided by the present invention, the vehicle-mounted ...
