Description
Technical field
The utility model relates to the tire tread proving installation of vehicle maintenance and repair, maintenance industry, and particularly one is by direct scanning survey tire tread, measures the concrete data of wearing and tearing and analyzes wear type, provides the tread 3D scanning analysis instrument of user's suggestion.
Background technology
The tread of tire is a very important security feature, is explicitly provided by law at the least depth of many national treads.When tire normally travels, tread directly contacts with road surface.The surface detail of tire can increase the holding power on cover tire and road surface and ensure the anti-side sliding power of vehicle necessity.The decorative pattern of tire is darker, then the elastic deformation amount of pattern block ground plane is larger, and the rolling resistance thereupon formed by tire flexibility hysteresis loss also increases thereupon.Therefore, the decorative pattern of tire is crossed and shallowly can be affected its water storage, drainage ability, and easily produce harmful " hydroplaning ", the drawback that tire is easily skidded shows especially out, thus makes the performance depreciation of automobile.And tire in the process of moving, continuous wearing and tearing can make tread more and more shallow.For this situation, just need special instrument and the tread degree of depth is detected, but the method for inspection comparatively generally used at present, the tread degree of depth directly measured by conventional gage, and this operation is very inconvenient, and precision is lower.
Summary of the invention
The purpose of this utility model is the defect solving above-mentioned existing tread depth detection instrument existence, and provides a kind of CMOS of employing image unit to gather tire surface image, with the tread 3D scanning analysis instrument of line laser structured light position measurements.

Detailed description of the invention
As shown in Figure 1, this scanning analysis instrument mainly comprises: rotary encoder, front driving roller, CMOS image unit, MCU microprocessing unit, keyboard/USB interface, LCD display unit, the reflective prism in right angle, laser transimitter, rear return idler.When detecting tread, laser transmitter projects linear light source, is radiated at surface of tyre at an angle.Because the position height of the illuminated laser spot of surface of tyre is different, in the reflective prism 7 in the right angle of another angle, a broken line is just defined to the imaging of the laser facula of surface of tyre.When the roller of scanner moves along tire width direction, in the reflective prism 7 in right angle, form the broken line of different size shape.In front driving roller 2 device rotary encoder 1 to roll this take turns surface of tyre roll angle measure, CMOS image unit 3 collection catches the imaging in the reflective prism 7 in right angle, MCU microprocessing unit 4 calculates the concavo-convex state of each point according to the principle of triangulation, analysis to measure result also in conjunction with genuine data, draws depth dimensions and the wear state of surface of tyre tread.
Rotary encoder 1 is arranged in front driving roller 2, front driving roller 2 and rear return idler 9 are fixed at the bottom of the box of scanning analysis instrument, the reflective prism 7 of CMOS image unit 4 and right angle, laser transimitter 8 are fixed on the box body of scanning analysis instrument, and other parts are separately fixed on the lid of scanning analysis instrument.
When detecting tire tread, the roller that major axis connects can avoid the pit of surface of tyre and groove on the impact of survey precision by actv..Front driving roller 2 and rear return idler 9 are close to surface of tyre simultaneously, and roll along tire width direction with measurement process.The roll angle of roller measured by rotary encoder 1, realizes the Division Sampling to surface of tyre rolling length.When laser transimitter 8 launches line source, when being radiated at surface of tyre at an angle, due to the existence of surface of tyre tread, make the position height of illuminated laser spot different, in the reflective prism 7 in the right angle of another angle, a broken line is just defined to the imaging of the laser facula of surface of tyre.When current driving roller 2 and rear return idler 9 move along tire width direction, in the reflective prism 7 in right angle, form the broken line of different size shape.CMOS image unit 3 gathers the imaging of hot spot in the reflective prism 7 in right angle that laser transimitter 8 irradiates at surface of tyre, MCU microprocessing unit 4 calculates the concavo-convex state of each point according to the principle of triangulation, analysis to measure result also in conjunction with genuine data, draws depth dimensions and the wear state of surface of tyre tread.Because laser transimitter 8 and surface of tyre exist certain angle, and the tread of surface of tyre has the groove of certain depth, thus surface of tyre understand some laser irradiate less than blind area.In order to dead zone-eliminating, the symmetric position of CMOS image unit 3 side shown in Fig. 2, places another laser transimitter, so not only can dead zone-eliminating, can also compensate, effectively improve survey precision to the error measured.
The result that tread detects can be presented on LCD display unit 6 with the form of mimic diagram, also result of a measurement graphically can be printed, for the tread process of tire provides intuitive and reliable theoretical foundation.
