Problems solved by technology

[0003] However, as the resistance knob increases in use time, the resistance value of the resistance in the resistance knob will become unstable, thus making the working stability of the resistance knob not high; and the coding knob and the grating knob are not only relatively high in cost, but also Moreover, the calculation logic of the encoder knob and the grating knob to calculate the knob switch is relatively complicated
Obviously, these three kinds of rotary switches will bring bad user experience to users

Abstract

The invention discloses a knob switch, which comprises a knob body. The knob body is provided with a closed cavity. The closed cavity is internally provided with a ball body. The inner wall of the closed cavity is paved by a pressure-sensitive resistor for sensing gravity change of the ball body in the turning process of the knob body. Compared with a computational logic in the prior art, the provided computational logic that resistance of the ball body produced in the turning process of the knob body is sensed by the pressure-sensitive resistor paved in the closed cavity, and the rotation angle of the knob switch is detected based on resistance change of the pressure-sensitive resistor collected by a controller is simple and easy to implement, thereby greatly improving user experience of a user during use of the knob switch. Correspondingly, the invention also discloses an intelligent automobile, which has the same beneficial effects above.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a rotary switch and a smart car. Background technique [0002] Knob switches can be seen everywhere in people's lives. Among the existing knob switches, according to the measurement method of the rotation angle of the knob switch, the knob switches can be divided into resistance knobs, coding knobs and grating knobs. Among them, when the resistance knob rotates, The rotation angle of the knob switch is judged by driving the change of the resistance value in the resistance knob; when the encoding knob is rotating, it moves by driving the encoder in the encoding knob, so that the two level pins in the encoder change, and then The rotation angle of the rotary switch is judged by detecting the change of the level pin in the encoder; when the grating knob is rotating, the rotation angle of the rotary switch is judged by driving the grating in the grating knob to move....
