Abstract

The utility model discloses an intelligent rotation device of a vehicle rearview mirror, comprising a rearview mirror main body, a rotary electric machine mounted in the rearview mirror main body and in transmission connection with a rotation axle of the rearview mirror main body; an angle sensor mounted on the rotation axle of a steering wheel and a rotation speed sensor mounted on the rotation axle of the wheel, wherein the angle sensor and the rotation speed sensor are connected with an A/D converter, the A/D converter is connected with an input end of a micro-processor, an output end of the micro-processor is connected with an electric machine drive circuit and the electric machine drive circuit is connected with the rotary electric machine. When the vehicle runs on the changed path or turns, the rearview mirror can rotates along the same direction with the vehicle turning angle, thus the rearview mirror can see the vehicle at the rear side at the real time and the traffic accident is prevented.

Description

Automobile rearview mirror intelligence wheel word
Technical field
The utility model relates to the automotive safety technical field, specifically belongs to automobile rearview mirror intelligence wheel word.
Background technology
Present automobile rearview mirror is divided into electronic control and manually controls dual mode, and general back mirror adopts plane mirror or dimpling lens, and the horizontal view angle is approximately 25-30 °, in use is subjected to certain restriction, and has certain dead angle.When automobile at the conversion road or when turning, for less than or the approximately obstacle or the vehicle at above visual angle, chaufeur all can't be seen, therefore has very big potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of automobile rearview mirror intelligence wheel word, automobile is when conversion road or turning, back mirror can be followed the automobile steering angle that turns round and be rotated in the same way in the lump, guarantees that back mirror can see the vehicle of rear side, the generation that tries to forestall traffic accidents in real time.
The technical solution of the utility model is as follows:
Automobile rearview mirror intelligence wheel word includes body of backsight mirror, and rotary electric machine is installed in the body of backsight mirror, and body of backsight mirror rotating shaft and rotary electric machine are in transmission connection; In the rotating shaft of bearing circle angular transducer is installed, in the rotating shaft of wheel tachogen is installed, angular transducer, tachogen are connected with the A/D converter, the A/D converter connects the input end of microprocessor, the mouth of microprocessor is connected with motor-drive circuit, and motor-drive circuit is connected with rotary electric machine.
Described rotary electric machine is a stepping motor.
Presetting body of backsight mirror hard-over value in the described microprocessor is 30 °.
Described bearing circle is that the rotational angular velocity of body of backsight mirror is 16 times.
Angular transducer of the present utility model is the rotational angle signal that is used for detecting bearing circle, and the rotational angle signal after converting the angle digital signal to, the A/D converter is input to microprocessor, microprocessor is handled the rotational angle signal of gathering and is calculated and by the rotational angle size of 16: 1 proportional control rotary electric machine, tachogen is used to detect the real-time speed of a motor vehicle of automobile, when the speed of a motor vehicle is lower than 30km/h, microprocessor sends actuation signal, rotary electric machine begins to start and just changes, bearing circle and body of backsight mirror rotate simultaneously in 16: 1 cireular frequency ratio, when the angle that back mirror rotates reaches 30 ° of microprocessor preset values, microprocessor sends reverse signal, and rotary electric machine begins counter-rotating and drive back mirror to get back to initial position.
The utility model is an automobile at the conversion road or when turning, and back mirror can be followed the automobile steering angle that turns round and be rotated in the same way in the lump, guarantees that back mirror can see the vehicle of rear side, the generation that tries to forestall traffic accidents in real time.
Description of drawings
Fig. 1 is schematic circuit diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing, automobile rearview mirror intelligence wheel word includes body of backsight mirror, and stepping motor 1 is installed in the body of backsight mirror, and body of backsight mirror rotating shaft and stepping motor 1 are in transmission connection; Angular transducer 2 is installed in the rotating shaft of bearing circle, tachogen 3 is installed in the rotating shaft of wheel, angular transducer 2, tachogen 3 are connected with A/D converter 4, A/D converter 4 connects the input end of microprocessor 5, the mouth of microprocessor is connected with motor-drive circuit 6, motor-drive circuit 6 is connected with stepping motor 1, and presetting body of backsight mirror hard-over value in the microprocessor is 30 °, and bearing circle is 16 times of the rotational angular velocities of body of backsight mirror.
