The invention has the advantages of convenient and quick test, accurate speed control and short accelerating stroke and can replace a real automobile to test parts of the automobile so that the test cost is greatly reduced.

Description

Part collision tester of electric automobile
Technical field
The present invention relates to a kind of car model collision test device, relate in particular to a kind of simulated collision test machine of testing automobile parts.
Background technology
In the impact test of automobile and works, need automobile is accelerated to the setting speed of a motor vehicle, and make it to collide with works.Because vehicle impact testing has to a certain degree danger and Unpredictability, so generally drives a car without the driver, but make the mode of instruction carriage acceleration by external force.At present, the method that instruction carriage is quickened mainly contains electric propulsion mode, hydraulic driving mode, tractor mode of traction or the like.Wherein the electric propulsion mode is to adopt more a kind ofly, and its major advantage is that control accuracy is higher.
But with regard to prior art, even if test also needs by the car load test to the crash tests of indivedual auto parts and components, inefficiency so not only, and cost of idleness greatly are unfavorable for that test of many times is to obtain accurate result.The production firm of some auto parts and components does not particularly need and does not possess true car test condition, carries out product test and has very big difficulty.Even domestic automobile parts crash tests is a blank at present.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of convenient test is quick, and speed control is accurate, and the part collision tester of electric automobile that accelerating travel is short can replace true car to test its parts, has greatly reduced testing cost.
In order to solve the problems of the technologies described above, the present invention is achieved by following technical scheme:
A kind of part collision tester of electric automobile, comprise that an end is provided with the collision barrier and is used for the running rail that model car slides, described model car is realized motion by the traction guiding mechanism, described traction guiding mechanism comprises driving wheel, circulation link chain and the engaged wheel that motor is installed, described model car be provided be used for being connected with described circulation link chain step up release unit automatically, the described release unit that steps up automatically comprises cam mechanism, and the spikes/low-points of described cam mechanism is connected with clamping device.
Described model car front end is provided with snubber assembly.
The invention has the beneficial effects as follows:
(1) the present invention can make model car be free to slide on running rail under the driving of traction guiding mechanism, and with certain speed bump collision barrier, to realize for the detection that is installed in the various products on the model car; For example, can test the impact resistance intensity of seat to being furnished with dummy's automotive seat impact.
(2) the automatic clamping release unit of installing on the model car has two kinds of functions: the firstth, clamp function, and model car is fixed on the circulation link chain, circulation link chain can drive model car and was synchronized with the movement this moment, thus the accelerator of implementation model car; The secondth, break away from function, model car and circulation link chain are broken away from fully, guarantee model car when arriving the regulation speed per hour, be not subjected to carry out impact test, the real simulation collision process with the experiment barrier under any external force effect.
(3) also be provided with snubber assembly on the model car, have two big functions equally: the firstth, crashproof function has avoided model car to be damaged in knockout process; The secondth, the impact control function, by the cushion stroke of control and change snubber assembly, come the collision buffering stroke of implementation model car, thereby controlling models car impact size (is the retarded velocity size of controlling models car, as 40G etc., 1G=1 the about 9.8m/s of acceleration of gravity 2).
(4), have convenient and swift and many characteristics such as speed control is accurate, accelerating travel weak point by the collision performance of this collision tester testing automobile parts.
(5) the present invention can replace true car to test its parts, greatly reduces the cost of each test; Particularly for the production firm of some auto parts and components, especially wherein do not need and do not possess the unit of true car test condition, brought Gospel,, and filled up this type of project testing blank at home therefore for the test of domestic automobile parts contributes.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the invention discloses a kind of part collision tester of electric automobile, comprise the model car 1 that is used for impact test, be equipped with on this model car 1 and step up relevant infrastructure device such as release unit 9, model people and snubber assembly 8 automatically.On the described model car 1 various auto parts and components products can be installed, carry out impact test, with the impact resistance intensity of testing automobile parts product.
Described model car 1 is free to slide in the stroke range of running rail 4, and the end of described running rail 4 is provided with a collision barrier 3.Described model car 1 will clash into described collision barrier 3 with certain speed.
The traction guiding mechanism that moves through of described model car 1 realizes that described traction guiding mechanism comprises driving wheel 7, circulation link chain 2 and the engaged wheel 5 that motor 6 is installed, and according to actual conditions, can also comprise some auxiliary wheels.Described motor 6 drive sprockets, thus drive circulation link chain 2 around driving wheel 7 and engaged wheel 5 cycle rotations.
Described model car 1 is clamped on the described circulation link chain 2 by stepping up release unit 9 automatically, and make the disengaging fully of model car 1 and circulation link chain 2 in a certain position moment realization of described running rail 4, guarantee model car 1 when arriving the regulation speed per hour, be not subjected to carry out impact test with collision barrier 3 under any external force effect.The described release unit 9 that steps up automatically comprises the cam mechanism that can manually control, and the spikes/low-points of described cam mechanism is connected with clamping device.Bump against the block of setting on the described running rail 4 when cam mechanism after, cam mechanism rotates and clamp system and described circulation link chain 2 is broken away from, and moves with implementation model car 1 and with the disengaging of circulation link chain 2.
Described model car 1 also is provided with snubber assembly 8, and described snubber assembly 8 is utilized the buffering of the resistance implementation model car 1 of a circulating oil path by two adjustable oil cylinders of stroke.Snubber assembly 8 avoids model car 1 to be damaged in knockout process on the one hand; The more important thing is that snubber assembly 8 utilizes the cushion stroke of oil cylinder in control and the change system, come the collision buffering stroke of implementation model car 1, thus controlling models car 1 impact size.That is to say the retarded velocity size of controlling models car 1,40G etc. for example, 1G=1 the about 9.8m/s of acceleration of gravity 2
Although in conjunction with the accompanying drawings the preferred embodiments of the present invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, can also make the conversion of a lot of forms, these all belong within protection scope of the present invention.
