A new energy vehicle electronic vacuum pump performance testing device

Abstract

The invention discloses a performance detection device for an electronic vacuum pump of a new energy vehicle, and relates to the technical field of electronic vacuum pump detection. It includes a workbench, a first lifting platform is arranged directly below the workbench, a fixed assembly is fixedly installed on the first lifting platform, screw slides are arranged on both sides of the first lifting platform, and the working The middle part of the table is provided with a channel for accommodating the fixed components, the top of the workbench is fixedly equipped with a soundproof cover, a water tank is provided on one side of the soundproof cover, and a second lifting platform is provided directly above the soundproof cover. Both sides of the bottom of the second lifting platform are provided with electric push rods, and a sound level meter is fixedly installed on the soundproof cover. After the second air intake pipe inflates the airbag and expands the airbag to clamp the electronic vacuum pump, the gas that continues to pass through passes through the second air outlet pipe at the other end of the airbag and enters the casing. While performing air tightness testing, it also ensures The inlet pipe and outlet pipe of the electronic vacuum pump are always in a sealed state.

Description

technical field [0001] The invention relates to the technical field of electronic vacuum pump detection, in particular to a performance detection device for electronic vacuum pumps of new energy vehicles. Background technique [0002] The vast majority of new energy vehicles are driven by electric motors, and the traditional engine is canceled, so the source of vacuum is lost, that is, it cannot provide vacuum boost for the brake master cylinder of the car. The electronic vacuum pump for new energy vehicles was created to make up for this deficiency. It adopts vehicle-mounted power supply to provide power, and pushes the motor on the pump body to move the piston to generate vacuum, which provides the only and reliable vacuum for hydraulic brake systems of various types of vehicles such as electric vehicles, hybrid vehicles, electric sightseeing vehicles, and electric track vehicles. source, thereby effectively improving the braking performance of the vehicle.

AI Technical Summary

Problems solved by technology

[0005] (1) Once the electronic vacuum pump enters water, it may cause irreparable damage to the internal components, so it is not suitable for batch testing;

[0006] (2) The electronic vacuum pump on the new energy vehicle may cause the internal rotor to reverse under the application condition of frequent start and stop, causing back suction phenomenon, inhaling water and dust, and causing internal damage to the electronic vacuum pump, so it is necessary to adjust the degree of back suction to test;

[0007] (3) The electronic vacuum pump will generate noise when it is in use. Excessive noise will affect the health of the driver. The country has corresponding noise standards, so it is necessary to detect the noise
