Summary of the invention
the purpose of this utility model is to solve the problem, and provides a kind of new device that can carry out distance survey on bend, solves the shortcoming that existing laser ranging is difficult at crooked road distance.
The technical solution of the utility model is as follows:
A kind of automobile cornering laser ranging system, comprises steering wheel angle sensor (1), A/D converter (2), (10), micro controller system (3), automobile circuit (4), signal amplification circuit (5), drive motor (6), retarder (7), tooth bar (8), laser transimitter (9), LCD display module (11), retarder input gear (12), output gear of speed reducer (13), cylindrical iron staff (14), supporting pin (15), affiliated steering wheel angle sensor out send the roll angle inspection of wheel and A/D converter, A/D converter is converted to digital signal detected analog signal, micro controller system receives the digital signal after A/D transforms and carries out analytical calculation to it, control drive motor by signal amplification circuit to rotate, drive motor drives the input gear of retarder to rotate, and then retarder is started working, because the design of this device be make automobile in turning driving process in aviation value and the laser transimitter of the outside wheel steering angle angle that swings consistent, reach the object at crooked road distance, the corner of wheel we transformed by steering wheel angle, because both have certain proportionate relationship, the rotating speed of stepping motor is also relatively high simultaneously, so at this retarder will installing a suitable transmitting ratio to adjust rotating speed and to turn to, output gear of speed reducer and the external toothing of tooth bar phase, achieve the transformation that rotary motion moves left and right, the rear end of the cylindrical iron staff and laser transimitter that are welded on tooth bar one end connects together, and energy flexible rotating and slip, supporting pin is provided with between cylindrical iron staff and laser transimitter, finally, laser transimitter image data, and gathered data by returning to micro controller system after A/D converter, LCD display module shows the two car spacings that micro controller system calculates.
It is emphasized that: steering wheel sensor is connected by wire with A/D, and micro controller system one end connects A/D, and the other end is connected with signal amplification circuit, and signal amplification circuit is connected by wire with drive motor; Drive motor is connected with the external toothing of retarder input gear, and output gear of speed reducer and tooth bar are placed and phase external toothing up and down; The tooth bar of horizontal positioned is together with the upper and lower vertical welding of cylindrical iron staff, and laser transimitter rear end and cylindrical iron staff connect together, and can rotate flexibly, slides, and is provided with a supporting pin between laser transimitter and cylindrical iron staff.
Advantage of the present utility model:
1, existing laser ranging system applicability when automobile straight-line travelling is better, then act on less during bend, this device overcomes the problems referred to above, makes chaufeur also can find front vehicles timely when bend, reduces the possibility that vehicle crashes on bend;
2. crooked road distance device volume is little, simple installation.
