Embodiment Construction

[0026] The specific content of the present invention and its specific implementation will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0027] refer to figure 1 , the tire profile identification device for placing the deflection angle of the axle of the invention is mainly composed of double guide rails A, base assembly B, stroke device C, and laser range finder D.

[0028] refer to figure 2 , the double guide rail A is the motion track of the base assembly B, and the movement of the base assembly B is realized by four base wheels 11 on its bottom surface. When the base assembly B moves on the double guide rail A, the laser range finder D collects data at all times, and automatically finds and locks the position of the rear wheel of the vehicle under inspection according to the obtained data curve. When returning to the position of the rear wheel again, the stepper motor 2 in the base assembly B stops automatically, and...

Abstract

The invention relates to a tyre outline recognition device of a car axle set oblique angle, belonging to performance detection equipment for a headlamp for a motor vehicle. The recognition device mainly comprises double guide rails (A), a base assembly (B), a stroke device (C) and a laser distance measuring instrument (D), wherein the base assembly (B) and the stroke device (C) are fixedly connected into a whole; the base assembly (B) is arranged on the double guide rails (A) through base wheels (11); driving wheels in the base wheels (11) are driven by a driving mechanism; the laser distance measuring instrument (D) is arranged on the stroke device (C) and driven by a motor to do linear motion; and the start scanning point of the laser distance measuring instrument (D) is precisely positioned through a stay wire sensor. The invention aims to detect an included angle between the axes of a back shaft of the motor vehicle and guide rails of a light meter during detecting the headlamp, and further corrects the detection result of the headlamp.

Description

[0001] This application is a divisional application. [0002] Title of original application: Method and device for tire profile identification of axle placement deflection angle; [0003] Application number: 2009100671344; [0004] Application date: 2009.06.14 technical field [0005] The invention belongs to performance testing equipment for automobile headlights, and relates to a tire contour recognition device for the tire contour recognition method of the deflection angle of the axle placement, which overcomes the current automobile detection line based on the body axis Inaccurate measurement results caused by benchmarking the technical condition of headlamps. The deflection angle of the driving direction is measured by the device, and then the detection result of the headlight is corrected. Background technique [0006] When driving at night, the technical condition of the headlights is very important to driving safety. In the new GB7258-2004 standard, it is propose...
