Problems solved by technology

[0002] At present, the vacuum booster pump assemblies of new energy vehicles are all arranged in the front cabin, and they are all rigidly connected to the dash panel. Vibration and electromagnetic noise close to the passenger compartment will be directly transmitted to the passenger compartment, which will have a great impact on the NVH performance of the vehicle
When a vehicle collides, the front end of the vehicle is deformed and squeezed, and the overall displacement of the vacuum booster pump enters the passenger compartment, resulting in structural changes in the living space of the occupants, which is not conducive to increasing the survival distance of the passenger.

Embodiment Construction

[0026] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0027] Such as Figure 1 to Figure 3 As shown, a noise reduction mounting bracket for a vacuum booster pump assembly includes a bracket body. The bracket body includes a horizontal frame 1 and a vertical frame 2 connected to each other. The vertical frame 2 is provided with a flexible shock absorbing structure for noise reduction. The horizontal frame 1. An installation structure for installing the vacuum booster pump 9 is reserved. The vacuum booster pump is installed on the horizontal frame through the installation structure, and the vibration and electromagnetic noise of the vacuum booster pum...

Abstract

The invention discloses a noise reduction installation support of a vacuum booster pump assembly. The noise reduction installation support comprises a support body. The support body comprises a transverse frame and a longitudinal frame which are connected. The longitudinal frame is provided with a flexible cushioning structure used for reducing noise. An installation structure for installing a vacuum booster pump is reserved on the transverse frame. Vibration and electromagnetic noise of the vacuum booster pump are effectively reduced, and the quiet space in a vehicle is enlarged.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a noise reduction mounting bracket for a vacuum booster pump assembly. Background technique [0002] At present, the vacuum booster pump assemblies of new energy vehicles are all arranged in the front cabin, and they are all rigidly connected to the dash panel. Vibration and electromagnetic noise close to the passenger compartment will be directly transmitted to the passenger compartment, which will have a great impact on the NVH performance of the vehicle. When the vehicle collides, the front end of the vehicle is deformed and the vacuum booster pump is displaced into the passenger compartment as a whole, which structurally leads to changes in the living space of the occupants, which is not conducive to increasing the survival distance of the passengers. Contents of the invention [0003] The present invention aims to solve at least one of the technica...
