Wheel positioning and indicating device

Abstract

The invention provides a wheel positioning and indicating device connected to a rotating shaft of a steering wheel. The wheel positioning and indicating device comprises a transmission module, a frequency control unit, a voltage output unit, a drive unit and a wheel positioning and indicating unit, wherein the transmission module comprises a sliding part and controls the position of the sliding part according to the rotating angle of the steering wheel; the frequency control unit comprises a slide rheostat and controls an output frequency in the position, where the sliding part slides, of the slide rheostat; the voltage output unit is connected with the frequency control unit and obtains output voltage according to the output frequency; the drive unit is connected with the voltage output unit and outputs a driving signal according to the output voltage; and the wheel positioning and indicating unit is connected with the drive unit and comprises a plurality of corner indicating lights, one corner indicating light corresponds to one corner of a wheel, and the wheel positioning and indicating unit turns on one corner indicating light according to the driving signal.

Description

【Technical field】 [0001] The invention relates to a wheel alignment indicating device, in particular to a wheel alignment indicating device which can indicate the wheel deflection angle. 【Background technique】 [0002] In today's living environment, cars have become the most important means of transportation in people's lives. However, most drivers will encounter the following troubles when parking: due to the large rotation angle of the steering wheel when parking, the driver often cannot know whether the wheels have returned to the parallel angle after the vehicle is parked, so the driver needs to probe Or get out of the car to check, which is very inconvenient and dangerous; and the driver sometimes ignores this action because of carelessness. When the steering wheel of the car is not straightened, it will also damage the pressure link system connected to the wheel. 【Content of invention】 [0003] The main purpose of the present invention is to provide a wheel alignme...
