New energy automobile electronic vacuum pump performance detection device

Abstract

The invention discloses a new energy automobile electronic vacuum pump performance detection device, and relates to the technical field of electronic vacuum pump detection. The device comprises a working table, a first lifting table is arranged under the working table, a fixing assembly is fixedly installed on the first lifting table, lead screw sliding tables are arranged on the two sides of the first lifting table, a channel for containing the fixing assembly is formed in the middle of the working table, and a sound insulation cover is fixedly installed at the top of the working table; and a water tank is arranged on one side of the sound insulation cover, a second lifting table is arranged over the sound insulation cover, electric push rods are arranged on the two sides of the bottom of the second lifting table, and a sound level meter is fixedly installed on the sound insulation cover. After a second air inlet pipe inflates an air bag and enables the air bag to expand to clamp an electronic vacuum pump, the continuously-introduced air passes through a second air outlet pipe at the other end of the air bag and is introduced into a sleeve, and it is guaranteed that the air inlet pipe and the air outlet pipe of the electronic vacuum pump are always in a sealed state while air tightness detection is conducted.

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
