Problems solved by technology

[0003] However, as far as the prior art is concerned, even the crash test of individual auto parts needs to pass the whole vehicle test, which is not only inefficient, but also greatly wastes cost, which is not conducive to multiple tests to obtain accurate results
In particular, some manufacturers of auto parts do not need and do not have the conditions for real vehicle testing, so it is very difficult to conduct product testing
At present, the domestic auto parts crash test is still a blank

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0019] As shown in Figure 1, the present invention discloses a crash test machine for parts of electric vehicles, including a model car 1 for the crash test. basic equipment. Various auto parts products can be installed on the model car 1, and a collision test is carried out to test the anti-collision strength of the auto parts products.

[0020] The model car 1 slides freely within the travel range of the running track 4 , and a collision barrier 3 is arranged at the end of the running track 4 . The model car 1 will hit the collision barrier 3 at a certain speed.

[0021] The movement of the model car 1 is realized by a traction guide mechanism, which includes a driving wheel 7 equipped with a motor 6, an endless chain 2 and a driven wheel 5, and may also include several auxiliary wheels according to actual conditions. The motor 6 drives the sprocket, thereby...

Abstract

The invention discloses a part collision tester of an electric automobile, comprising a running track, one end of the running track is provided with a collision barrier, and the running track is used for an automobile model to slide. The automobile model realizes movement through a traction guiding mechanism comprising a driving wheel provided with a motor, a circulating chain and a driven wheel and is provided with an automatic quickening separating device for connecting with the circulating chain, the automatic quickening separating device comprises a cam mechanism, and the high point and the low point of the cam mechanism are connected with clamping fixtures; and the automobile model is also provided with a buffer device. 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

technical field [0001] The invention relates to an automobile model crash test device, in particular to a simulated crash test machine for testing auto parts. Background technique [0002] In the collision test between a car and a structure, it is necessary to accelerate the car to a set speed and make it collide with the structure. Because the car crash test has a certain degree of risk and unpredictability, generally the driver does not drive the car, but accelerates the test car by external force. At present, the methods for accelerating the test vehicle mainly include electric traction, hydraulic drive, tractor traction and so on. Among them, electric traction is the most widely used method, and its main advantage is high control accuracy. [0003] However, in terms of the prior art, even the crash test of individual auto parts needs to pass the whole vehicle test, which is not only inefficient, but also greatly wastes cost, which is not conducive to multiple tests to ...
