Abstract

The invention discloses a pendulum type automobile instrument collision test device.The device comprises an instrument fixing module, a signal simulation module, a collision generation module and a shooting device.The instrument fixing module is used for fixing an automobile instrument; the signal simulation module can simulate and generate different test conditions of automobile speeds and engine revolution speed signals and drives the instrument needle to rotate; the collision generation module comprises a swing arm and a mass block and is used for simulating different levels of collision energy, and collision simulation of the automobile instrument is realized; the shooting device records the needle indication conditions before and after collision of the automobile instrument.According to the pendulum type automobile instrument collision test device, collision simulation test can be performed to automobile instruments in all kinds of actual operation, the needle indication problems of the automobile instruments can be studied in the automobile collision process, various test conditions can be realized by the device, and the device is applicable to all types of automobile instruments.

Description

technical field [0001] The invention relates to a pendulum-type automobile instrument collision test device, which belongs to the technical field of automobile instrument testing. Background technique [0002] As an important part of the car, the car instrument is the most important way for human-vehicle information interaction. It can display various operating parameters, faults and other information of the vehicle. According to its structural principle, the car instrument can be divided into mechanical, electrical, and analog circuits. Whether it is an early mechanical instrument or a digital instrument that is widely used today, in terms of display methods, the pointer display method has always occupied a dominant position because of its good intuitiveness. [0003] Some studies and actual accidents have shown that under special circumstances, when a vehicle collides, the pointer of the car instrument with pointer display will be stuck, and the pointer will point to a cer...

Problems solved by technology

[0004] In the process of vehicle collision, automobile instruments usually encounter working conditions such as impact, first impact and then power failure, and first power failure and then impact. Researching the above problems through real vehicle crash tests is close to the real collision situation, but it consumes a huge amount of manpower physical force, and the cycle is long, if the different working conditions encountered by the automobile instrument in the vehicle collision can be simulated through an independent test device, the research purpose will be effectively achieved

At present, there are few types of test devices for automobile meters. Chinese patent 201310067728.1 discloses a CAN network-based automobile meter durability test bench. At present, there is no test device capable of simulating the different working conditions encountered by automobile instruments in vehicle collisions, so the pendulum-type automobile instrument crash test device is of great significance for solving the above problems
