Embodiment 1

[0029]When the real north-south weather needs to be simulated, the air conditioner 9 can be adjusted to control the temperature in the box body 1, so that the temperature in the box body 1 is closer to the real automobile working environment, thereby obtaining In order to obtain more realistic test results, it should be noted that when performing this test, the cover plate 4 needs to be closed so that the box body 1 is in an airtight environment.

Embodiment 2

[0031] When it is necessary to change the pressure on the brake pedal 5, the position of the adjustment block 21 can be adjusted. When the position of the adjustment block 21 is on the upper part, the distance between the gasket 19 and the movable plate 7 becomes longer, so that the spring 20 The amount of deformation produced becomes smaller, so that the elastic force provided by the spring 20 becomes smaller, that is, the pressure on the brake pedal 5 becomes smaller; when the position of the adjustment block 21 is lower, the distance between the gasket 19 and the movable plate 7 becomes shorter, Therefore, the amount of deformation generated by the spring 20 is increased, and the elastic force provided by the spring 20 is increased, that is, the pressure on the brake pedal 5 is increased.

Abstract

The invention discloses a durability testing device of a new energy automobile. The durability testing device comprises a box body and a brake assembly, a temperature adjusting mechanism is arranged at the upper end of the box body, a driving motor is installed on the outer side wall of the box body, and an opening is formed in the upper end of the box body, a cover plate is hinged in the opening,the brake assembly is installed on the inner side wall of the box body and comprises a brake pedal, a pressing plate is slidably connected in the box body, the pressing plate is located right above the brake pedal, a movable plate is arranged on the upper side of the pressing plate, one end of the movable plate is slidably connected with the upper end of the pressing plate, the other end of the movable plate is in sliding connection with the inner side wall of the box body, a reset mechanism is arranged at the upper end of the movable plate, the reset mechanism is in transmission connection with a drive motor through a transmission mechanism, and a threaded rod which is vertically arranged is fixedly connected in the box body. According to the invention, the pressing plate is used for simulating manpower to tread the brake pedal, so that the aim of testing the durability of the brake assembly is achieved, and different testing requirements can be met by controlling different variables.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a durability test device for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, other new energy vehicles, etc., and mainly pure electric vehicles. Most of the pure electric vehicles are not equipped with clutches, and the driver generally only needs to control the accelerator pedal and brake pedal when driving. Therefore, it is particularly important to perform durab...
