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 present application discloses a knob switch, comprising: a knob body, a closed cavity is arranged on the knob body, a sphere is arranged in the closed cavity, and the inner wall of the closed cavity is laid with a sensor for sensing the gravity change of the sphere during the rotation of the knob body. value of the varistor, and the knob body is also provided with a controller for collecting the resistance value of the varistor and determining the rotation angle of the knob body according to the resistance value. Obviously, compared with the prior art, the resistance value generated by the sphere during the rotation of the knob switch is sensed by the piezoresistor laid on the inner wall of the closed cavity, and the resistance value of the piezoresistor collected by the controller The calculation logic of detecting the rotation angle of the rotary switch by changing the value is simple and easy to implement, thereby greatly increasing the user experience of the user in the process of using the rotary switch. Correspondingly, a smart car disclosed in the present application also has the above beneficial effects.

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....
