Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] see Figure 1 to Figure 3 , the rear longitudinal beam assembly shown in , including the rear longitudinal beam body 1 formed by casting aluminum alloy, reduces the weight of the rear longitudinal beam assembly on the premise of meeting the structural strength performance requirements, and realizes the lightweight of the vehicle body.

[0023] As shown in the figure, the rear side beam body 1 is located on the left side of the vehicle, the left side is the outside of the vehicle, and the right side is the inside of the vehicle. The top plate 11 and the side plate 13 of the bottom plate 12, the middle section of the top plate 11 is integrally formed with an upwardly extending mounting protrusion 111, and the mounting protrusion 111 is provided with three first mounting holes 112 for fixing the shock absorber and A plurality of first reinforcing ribs 113 run th...

Abstract

The invention discloses a rear longitudinal beam assembly and a vehicle, comprising a rear longitudinal beam body, the rear longitudinal beam body is a U-shaped groove with an opening facing the outside, and includes a top plate, a bottom plate, and a side plate connecting the top plate and the bottom plate. The middle section of the top plate is integrally formed with an upwardly extending mounting protrusion, and the mounting protrusion is provided with a first mounting hole for fixing the shock absorber and a plurality of first reinforcing ribs running through the top surface and side of the mounting protrusion; The side plate is provided with an inwardly recessed escape groove at a position corresponding to the mounting protrusion, and the bottom plate is provided with an avoidance gap at a position corresponding to the escape groove. It can solve the problems of poor manufacturability, low structural strength and heavy weight of the existing sheet metal rear longitudinal beam.

Description

technical field [0001] The invention relates to the technical field of longitudinal beams of vehicles, in particular to a rear longitudinal beam assembly and a vehicle. Background technique [0002] The rear longitudinal beam is the installation carrier of the rear shock absorber, and it is also a key stress-bearing part of the rear of the vehicle body. At present, the fixed structure of most automotive rear shock absorbers is welded by multiple pieces of sheet metal, which has a complex structure, low structural strength, poor welding process, and is not conducive to weight reduction. The fixed structure of the rear shock absorber is the main stress-bearing part of the vehicle body. It will be continuously subjected to impact loads during driving and has high requirements for strength. Long-term use will cause deformation and seriously affect the performance of the rear of the vehicle body. [0003] CN209241171U discloses a kind of automobile rear longitudinal beam assembl...
