Accompanying drawing explanation
With reference to accompanying drawing, disclosure of the present invention will be more obvious.Should understand, these accompanying drawings only for illustration of object, and be not intended to limit protection scope of the present invention.In figure:
Fig. 1 is the overall schematic according to the overall dimensions of a car measurement mechanism of one embodiment of the present invention and the model of measuring method; And
Fig. 2 is the light path schematic diagram of the overall dimensions of a car measurement mechanism of embodiment as shown in fig. 1 and the model of measuring method.
Embodiment
Explain the specific embodiment of the present invention with reference to the accompanying drawings.In order to the object explained and illustrate, provide many details in the following description, to understand in depth the invention provides.But these details may be optional or preferred features, do not have these details, and this invention still can be implemented.
Fig. 1 is the overall schematic according to the overall dimensions of a car measurement mechanism of one embodiment of the present invention and the model of measuring method.As shown in Figure 1, the module comprised according to the overall dimensions of a car measurement mechanism of illustrated embodiment of the present invention has pointolite 1, concave mirror device 2, landing (not shown) and projection screen 4.Alternatively, pointolite 1 can be LED point light source, its saves energy and brightness is higher; Projection screen can be then the projection screen of mark cun scale, is convenient to directly read measurement size.Can understand, also can select pointolite and the projection screen of other common type, such as, pointolite can select fluorescent bulb etc.
As shown in fig. 1, pointolite 1 is positioned over the focus place of concave mirror, the light that the pointolite being positioned at focus place sends will produce directional light through the reflection of concave mirror, vehicle 3 to be measured is docked at the middle section (such as now landing is positioned at the middle section of directional light) of directional light, allow all regions of vehicle to be measured completely cover by directional light, the projection screen 4 with grid scale is positioned over the position of rear view of vehicle to be measured 1 to 2 meter.Because directional light irradiates, by the light that vehicle to be measured stops, shade is presented on screen with a scale, according to the region that shade covers, with reference to the scale on projection screen, reads the relevant required size of vehicle to be measured fast.It is important to note that projection screen 4 needs vertical with aforementioned directional light, and projection screen 4 is parallel with the dimensional directions to be measured of vehicle to be measured.Meanwhile, camera Taking Pictures recording coherent video can be used, for subsequent data analysis.
Those skilled in the art can understand, and this verification method can be generalized to the car load correlation parameters such as Quick Measurement ground clearance of machine, departure angle, approach angle, can measure relevant required size according to the shade of projection and scale size; These parameters and size all belong to overall dimensions of a car mentioned in the present invention.
Fig. 2 is the light path schematic diagram of the overall dimensions of a car measurement mechanism of embodiment as shown in fig. 1 and the model of measuring method.Can understand according to Fig. 2, principle of the present invention is that the light adopting concave mirror device to be sent by pointolite converts directional light to and and then realizes on the shadow-casting of vehicle to projection screen with directional light.Send light beam by pointolite, reflect to form directional light through concavees lens, parallel radiation, on vehicle to be measured, by the shadow-casting of vehicle in the plane of band size, intuitively reflects the relative dimensions of car load fast, and can read record relative dimensions fast.Can convenient and swift relative dimensions of reacting car load intuitively according to method and apparatus of the present invention, collect the relative position that above-ground route data, departure angle, approach angle, ground clearance of machine and correlated parts are arranged, and measurement mechanism is built conveniently, it is simple to use, measurement result is clear and intuitive, can measure for different vehicles.
Benefit of the present invention comprises and is not limited to collect the data such as the overall dimensions of a car of a large amount of competition vehicle in the vehicle early development stage with a kind of low cost, quick, accurate and visual method, can apply to intra-company and outside is measured associated vehicle.
