Abstract

The invention relates to a position finder for a vehicle, in particular to a position finder which is suitable for big vehicles such as passenger cars and goods vans and belongs to the technical field of vehicle localization devices. The position finder for the vehicle comprises a laser. The laser sends a laser beam on a sensor, the sensor is arranged in the middle of an axle, a positioning device is arranged at two ends of a cross beam of a vehicle body, the positioning device is formed by two positioning rods which are vertical to each other, and the two positioning rods are connected through an articulated shaft. The position finder for the vehicle directly measures the axle, measures if the axle and the cross beam of the vehicle body are vertical or not and a front axle and a back axle are parallel or not, especially to a trailer, and the phenomenon of throwing and hanging can be avoided. Data information received by the sensor is sent to a computer. The computer accurately works out offset distance and angle of the axle, so that precise adjustment is carried out on the axle, and safety of the vehicle driving is guaranteed.

Description

The vehicle orientator

Technical field

The present invention relates to the vehicle orientator, especially be applicable to the orientator on the carts such as passenger vehicle, lorry, belong to the Vehicle Positioning Equipment technical field.

Background technology

High speed development along with China's economic and technology, China has become the third-largest automobile industry state, the prospect in cart markets such as its microbus, lorry is boundless, Zhong Guo highway system is also little by little covering comprehensively in addition, this has also driven developing rapidly of industries such as logistics, make that the large car, the heavy goods vehicles that put into effect are also more and more, therefore also more and more higher to security and the stability of vehicle.All adopt at present the mode of vehicle location to guarantee security and the stability of vehicle, vehicle location also had following benefit: (1), reduction oil consumption, (2) reduce chassis suspender wearing and tearing, thereby guarantee the security of vehicle, (3), reduce the tire irregular wear, thereby prolong its life-span, (4), increase work efficiency additional income.At present following several mode is mainly adopted in vehicle location: (1), employing laser are got to the mode of a bit, and the wheelbase before and after (2), employing laser range finder are measured is poor, and (3), employing dipstick metering wheel hub are to the distance of towing pin.More than several modes have following shortcoming: (1) adjusts the influence that the result will be subjected to the vehicle bridge left-right deviation in case deviation is arranged about vehicle bridge, and namely departure is more big, and error is more big, the easy eccentric wear of tire; (2), use stadia surveying, can only guarantee before and after bridge parallel, whether can not measure vehicle bridge vertical with the vehicle body crossbeam, what will cause vehicle body and tractor like this is subjected to force direction inconsistent, thereby the generation " getting rid of extension " phenomenon; (3), cost of manufacture height.

Summary of the invention

The objective of the invention is to solve the weak point that above-mentioned prior art exists, a kind of reasonable in design, cost is low, measurement is accurate, error is little vehicle orientator are provided.

The present invention is achieved by the following technical solutions:

The vehicle orientator, its special character is to comprise laser instrument 1, the laser beam 3 of laser instrument 1 emission is got on the sensor 5, sensor 5 is installed in the centre position of vehicle bridge 6, vehicle body crossbeam 2 two ends are equipped with locating device 4, locating device 4 is made up of two orthogonal backstays 7, connects by jointed shaft 8 between two backstays 7;

Described sensor 5 is PSD sensor or ccd sensor or cmos sensor or laser sensor.

Vehicle orientator of the present invention, directly vehicle bridge is measured, whether measure vehicle bridge vertical with the vehicle body crossbeam, whether the front and back bridge is parallel, especially for trailer, can avoid occurring " getting rid of extension " phenomenon, the data message that sensor receives is sent on the computer again, accurately calculate offset distance and the angle of vehicle bridge by computer, thereby vehicle bridge is made accurate adjustment, guarantee the security that vehicle travels.

Embodiment

Provide the specific embodiment of the present invention below with reference to accompanying drawing, be used for formation of the present invention is described in further detail.

The vehicle orientator of present embodiment, comprise laser instrument 1, the laser beam 3 of laser instrument 1 emission is got on the sensor 5, sensor 5 is installed in the centre position of vehicle bridge 6, vehicle body crossbeam 2 two ends are equipped with locating device 4, locating device 4 is made up of two orthogonal backstays 7, connects by jointed shaft 8 between two backstays 7; Sensor 5 is cmos sensor.

Principle of work: during use, sensor is installed in the centre position of vehicle bridge, launch laser beam with laser instrument again, laser beam adopts two locating devices to position, guarantee that laser beam beats the middle in vehicle bridge, laser beam is beaten on sensor at last, and the data message that receives on the sensor sends computer to by RF again, accurately calculates the information such as deviation angle of vehicle bridge by computer.As shown in Figure 3, when vehicle bridge was vertical with crossbeam, laser beam was just in time beaten the center at sensor, and need not adjust vehicle bridge this moment; Shown in Figure 4, vehicle bridge and crossbeam be out of plumb, and at this moment laser beam just can not be beaten the center at sensor, but concrete offset data passes through just accurate Calculation of computer, and adjust vehicle bridge again and get final product this moment, vertical with crossbeam until vehicle bridge.

The unspecified content of the present invention is prior art, and those skilled in the art can obtain to inspire from present embodiment and prior art, is out of shape to obtain other embodiment.Therefore, protection scope of the present invention should be determined according to the protection domain of claim.
