Abstract

The invention discloses a touch key, a steering wheel assembly and an automobile. The touch key comprises a housing; a touch panel assembly fixed on the shell and matched with the housing to define amounting space; an actuating connecting piece connected with the inner peripheral wall of the touch panel assembly; a supporting piece connected with the inner peripheral wall of the touch panel assembly; an actuator mounted in the mounting space; a signal processing circuit comprising a pressure sensor arranged on the supporting piece; and a processor electrically connected with the signal processing circuit and the actuator. When the touch panel assembly is pressed, the supporting piece generates elastic deformation, so that the pressure sensor generates a pressing electric signal, the signal processing circuit processes the pressing electric signal into a readable electric signal, the processor obtains a pressing pressure value according to the readable electric signal, and when the pressing pressure value is not smaller than a preset pressure value, the actuator adsorbs and desorbs the actuation connector to drive the touch panel assembly to vibrate. According to the technical scheme, the touch key has the functions of vibration feedback and mistaken touch prevention.

Description

Technical field

[0001] The present invention relates to the field of touch devices, and in particular, to a touch button, a steering wheel assembly, and a car.Background technique

[0002] Cars typically have steering wheels and multimedia devices, etc., the steering wheel and multimedia devices are typically provided with buttons. Some steering wheels and multimedia devices are configured with touch buttons. However, since the touch button usually lacks tactile feedback, the driver is easy to know if the touch control of the touch button is effective, and the touch button is also easy to trigger and the driver is unknown, which affects the safety of the car Sex.

[0003] The above is only used to assist in understanding the technical solutions of the present invention, and does not represent the above content is prior art.Inventive content

[0004] The primary object of the present invention is to propose a touch button to make the touch button both vibration feedback and anti-character.
