Description

One kind test target car

Technical field

The utility model belongs to Automobile Measuring Techniques field, and in particular to one kind test target car.

Background technology

Automobile is when ACC/AEB experiments are tested, it is necessary to using nobody target car, test target that the current country uses The type of car one is to be placed on the test of road center with the model target car of vacation, and another is that directly with trailer, false model target car exists in tow Moved on road.First way is immovable, can only do some simple tests, although second can move, speed is not 80Km/H can be reached, test request can not be met.And both the above situation can all make when test carriage touches building to target car Target car damages completely, while test carriage will also result in different degrees of damage, has not only reached the effect of test but also can cause serious Loss and safety problem.

Utility model content

The purpose of this utility model is to provide a kind of simple in construction, and cost is low, reusable, and can reach ACC/AEB Test the test target car of effect.

The utility model provides following technical scheme：

One kind test target car, including model target car assembly, glide base assembly and flat car, the model target car assembly lead to Cross screw to be fixed on the glide base assembly, if the glide base assembly includes glide base and dry bearing, the axle The both sides for being symmetrically mounted on the glide base are held, the flat car includes pedestal and some wheels, and the wheel is symmetrically installed In the both sides of the pedestal, the pedestal is provided with the slide rail corresponding with the bearing, and one end of the slide rail is provided with triggering Sensor, is provided with sliding guide groove between the pedestal and the trigger sensor, the trigger sensor is led by the slip Groove is arranged on the pedestal, and positioned at one end of the slide rail, plays a part of detection and localization.

Preferably, traction tracheae connection handle is additionally provided with the pedestal, traction tracheae can be installed, so as to drive whole model Target car.

Preferably, the height of the pedestal is less than or equal to 100 millimeters, is easy to test carriage smoothly to be slipped over from whole flat car Go.

Preferably, the wheel is high intensity wheel, and the supporting power of the high intensity wheel is at least two tons, can born whole The weight of individual automobile.

Preferably, the inwall of the slide rail is smooth inner wall, the bearing is smoothly slided in slide rail.

Preferably, the slide rail is aluminum alloy guide rail, and the aluminum alloy guide rail of high intensity is unlikely to deform and weight capacity is strong.

The beneficial effects of the utility model are：Overall structure is simple, and cost is cheap, can reach speed using flat car More than 80Km/H, reach ACC/AEB test effect；Solve in AEB/ACC test process, false model target car and test carriage are not It can damage, false model target car may be reused, and reduce testing cost loss, while ensure that the safety of experimenter.

Embodiment

As shown in Figure 1-Figure 3, a kind of test target car, including model target car assembly 1, glide base assembly 2 and flat car 3, Model target car assembly 1 is screwed on the assembly of glide base 2, and glide base assembly 2 includes glide base 22 and four Bearing 21, bearing 21 are symmetrically mounted on the both sides of glide base 22 two-by-two, and flat car 3 includes pedestal 31 and four wheels 32, car The both sides that wheel 32 is symmetrically mounted on pedestal 31 two-by-two, pedestal 31 are provided with the slide rail 33 corresponding with bearing 21, and the one of slide rail 33 End is provided with trigger sensor 34.Further, traction tracheae connection handle 35 is additionally provided with pedestal 31, traction tracheae can be installed, from And drive whole model target car；The height of pedestal 31 is less than or equal to 100 millimeters, is easy to test carriage smooth from whole flat car 3 Slip over；Wheel 32 and bearing 21 are high intensity wheel, and the supporting power of high intensity wheel is at least two tons, can bear whole automobile Weight.

As Figure 3-Figure 4, sliding guide groove 341 is provided between pedestal 31 and trigger sensor 34, trigger sensor 34 is logical Sliding guide groove 341 is crossed on pedestal 31, and positioned at one end of slide rail 33, plays a part of detection and localization.

As shown in figure 5, glide base assembly 2 is stuck in the inner face of slide rail 33 of four-wheel flat car 3 by glide base bearing 21, The inwall of slide rail 33 is smooth inner wall, bearing 21 is smoothly slided in slide rail 33；Slide rail 33 is aluminum alloy guide rail, high intensity Aluminum alloy guide rail be unlikely to deform and weight capacity is strong.Slide rail 33 clips four bearings 21 of glide base assembly 2, trailer dragging Model target car is allowed to swing in driving process, the trailing wheel of the just contact slide pedestal assembly 2 of trigger sensor 34, flat board Car 3 prevents target car from being moved rearwards when motion.

As Figure 1-Figure 5, a kind of test process for testing target car：Band of the whole model target car assembly 1 in traction tracheae Under dynamic, travelled forward with 80Km/h speed, in motion process, when test carriage encounters test target car, four-wheel flat board Two trigger sensors 34 of car 3 are immediately detected, and cause triggering, power off demagnetization, work of the trigger sensor 34 in gravity immediately Moved downward under along sliding guide groove 341, relieve the trailing wheel limitation of glide base 22.Then whole model target car assembly 1 Depart from four-wheel flat car 3 in the case where the four wheels 32 of four-wheel flat board pedestal 31 drive, avoid test carriage and target car because building is hit and Target car and test carriage is caused to damage, and test carriage directly can roll over from flat car 3, because flat car 3 only has 100 millimeters It height, can be passed through from automobile chassis, so both protect the safety of test carriage, model target car is not damaged again, reach weight The effect of using again.

Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, although ginseng The utility model is described in detail according to previous embodiment, for those skilled in the art, it still can be with Technical scheme described in foregoing embodiments is modified, or equivalent substitution is carried out to which part technical characteristic.It is all Within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., this practicality should be included in Within new protection domain.
