Energy storage automobile instrument collision test apparatus

Abstract

The invention discloses an energy storage automobile instrument collision test apparatus. The apparatus herein includes an instrument fixing module, an impact energy storage module, a signal simulation control module and a camera module. The instrument fixing module is intended for fixing a to-be-tested automobile instrument. The impact energy storage module is intended for simulating the speed and energy of collision of different levels of the to-be-tested automobile instrument. The signal simulation control module is intended for generating a vehicle speed signal and an engine rotating speedsignal which are intended for driving a pointer of the to-be-tested automobile instrument to rotate, and generating a drive signal for driving the impact energy storage module to perform vertical impact to a bottom plate, and for controlling the electrical connection and disconnection of the to-be-tested automobile instrument. The camera module is intended for recording the indication of the pointer of the to-be-tested automobile instrument prior to and after the collision. According to the invention, the apparatus herein can effectively increase impact speed.

Problems solved by technology

[0002] At present, the public security traffic control department usually uses audio-visual data, trace inspection, and electronic data to inspect and judge the driving speed of the accident vehicle in the handling of road traffic accidents. The comprehensive application of the above-mentioned various technical means can realize the The rapid determination of driving speed has created great convenience for quickly clarifying the accident responsibility and realizing the rapid handling of road traffic accidents. However, some problems and deficiencies have been exposed in the actual application process, such as the speed identification based on audio-visual data. It is based on video inspection materials with stable frame rate and clear viewing angle; vehicle speed identification based on trace inspection is usually suitable for typical accident forms, and there are certain calculation errors; Equipment vehicles are helpless

[0003] In the actual operation of the vehicle, the value indicated by the speed pointer of the vehicle instrument can also objectively reflect the real-time speed of the vehicle. Whether the residual information of the vehicle instrument pointer represents the speed of the vehicle at the time of the collision is still inconclusive

[0004] The driving source of the speed pointer of the existing mainstream vehicle instrument usually adopts a stepper motor. In view of the phenomenon that the speed pointer of the vehicle instrument is stuck in a traffic accident, the residual information cannot be used to represent the speed of the vehicle when it collides. Research and analysis on the relationship between the indicated value when the vehicle speed pointer of the motor vehicle instrument is locked and the vehicle speed at the time of the accident will open up a new way for the vehicle speed identification in road traffic accidents involving this situation

[0005] In order to conduct research on the above problems, it is necessary to research and develop a set of automobile instrument crash test equipment, which can simulate the working conditions such as impact, power failure after collision, and power failure and collision that may be encountered by vehicle instrument during vehicle collision. Therefore, Chinese patent CN201710082870.1 discloses an air pump guide rail type vehicle instrument collision verification device, which adopts the form of horizontal guide rail collision impact to realize the collision test for the test vehicle instrument, but the horizontal guide rail impact method is easy to Because the gravity of the slider produces a certain amount of damping force in the impact direction, the effective collision speed is reduced and the stability of the slider during high-speed motion is greatly disturbed.
