Engine compartment bracket assembly mounting structure and vehicle

Abstract

The invention provides an engine compartment bracket assembly mounting structure. A chassis left suspension connected with a left longitudinal beam reinforcing assembly and a right suspension connected with a motor mounting bracket are correspondingly arranged at the two ends of an engine compartment bracket front cross beam assembly and an engine compartment cross beam assembly; the chassis leftsuspension and the right suspension can reduce and control the transmission of vibration of an engine compartment bracket and have a supporting effect. Compared with a hard connection mode in the prior art, the engine compartment bracket assembly mounting structure provided by the scheme has the advantages that an effect of realizing soft connection between the whole engine compartment bracket anda whole vehicle body structure can be achieved; requirements on strength and rigidity can be satisfied; requirements on vehicle stability can also be satisfied; the vibration amplitude of a vibrationsource is reduced to avoid the forming of resonance; and therefore, performances, such as NVH and safety grade, of the whole vehicle are obviously improved. The invention further provides a vehicle with the engine compartment bracket assembly mounting structure.

Description

Technical field [0001] The invention belongs to the technical field of automobile body parts, and particularly relates to a cabin bracket assembly installation structure and a vehicle. Background technique [0002] See figure 1 with figure 2 At present, the installation structure of automobile engine room bracket assembly basically adopts two horizontal beams. The beam structures are all open structures without forming a closed structure. Under the connection of several longitudinal beams, they are rigidly connected with the longitudinal beams of the body nacelle through the cabin adapter bracket. This kind of nacelle support structure is not stable enough, rigidity and strength are not high. Considering the extreme working condition requirements of pure electric vehicle motor at maximum speed and maximum braking force, this design structure has certain hidden dangers, and it is difficult to meet the high requirements of pure electric vehicles. Level of safety standard requireme...

AI Technical Summary

Problems solved by technology

This kind of cabin support structure is not stable enough, and its rigidity and strength are not high. Considering the extreme working conditions such as the maximum speed of the pure electric vehicle motor and the maximum braking force, this design structure has certain hidden dangers, and it is difficult to meet the high requirements of pure electric vehicles. Level Safety Standard Requirements

see figure 2 , the traditional cabin bracket and the body longitudinal beam are directly connected by bolts, the connection method is too rigid and there is no flexible transition, so it is easy to increase the vibration of the whole vehicle during driving, which seriously affects the safety level of the whole vehicle, NVH (Noise, Vibration, Harshness, Noise, vibration and harshness) and other performance
