In be easy cause twisting vibration, bring abnormal sound.
Summary of the invention
The purpose of this utility model is to propose a kind of back wall reinforcement structure, in the design basis of existing automobile rear wall structure
On, by the design of back wall assembly reinforcer, the structural strength of back wall assembly is promoted, reduces the torsion vibration in vehicle traveling process
It is dynamic, avoid the generation of abnormal sound.
The back wall reinforcement structure of the utility model, including rear wall outer plate, back wall inner panel and back wall connecting plate, outside the back wall
Plate connects the cavity to form inner transverse perforation with the two sides of back wall inner panel by back wall connecting plate, it is critical that after further including
Stiffening plate is enclosed, the rear wall reinforcing plate is the box body structure of one side opening, including bottom surface and multiple sides；The rear wall reinforcing plate
The vertical two sides for being set to the cavity, and connect by the side with the back wall inner panel and rear wall outer plate.This back wall adds
Strong structure increases separately rear wall reinforcing plate in the position that the two sides of cavity are equipped with back wall connecting plate, and is fixedly connected with it outside back wall
Plate and back wall inner panel form reinforcement structure, and under the premise of weight and increased costs very little, it is strong to greatly improve back wall assembly
Degree, improves body torsional rigdity, optimizes vehicle NVH performance.
Further, the side is connect by welding manner with the back wall inner panel and rear wall outer plate.Welding manner connects
It connects securely, it is not easily to fall off, more greatly improve the stiffness and strength of back wall assembly.Specifically: in rear wall reinforcing plate and back wall
Plate, back wall connecting plate form three layers of welding, and rear wall reinforcing plate and rear wall outer plate form two layers of welding.
Further, at least two sides are connect with back wall inner panel with welding manner on rear wall reinforcing plate；At least one side
Face and rear wall outer plate are connected with welding manner.Solder joint is set on the multiple sides of rear wall reinforcing plate, makes it in cavity and back wall
The connection of outside plate and back wall inner panel is more secured, forms strong connection and support to back wall assembly, keeps its overall structure more firm
Gu.
Further, pass through arc transition between the side and bottom surface；Pass through arc transition between the adjacent side.
The setting that angle is formed between compared to two faces of arc transition, more conducively improves the overall stiffness and intensity of rear wall reinforcing plate.
Further, the bottom surface is equipped with lightening hole and reinforcing rib；The bottom surface is equipped with location hole.Bottom surface lightening hole
It also can guarantee whole stiffness and strength while so that rear wall reinforcing plate is mitigated weight with the setting of reinforcing rib；Location hole is used for
Positioning when installation, convenient for welding installation.
Back wall is added in the two sides of the back wall reinforcement structure of the utility model, the cavity between rear wall outer plate and back wall inner panel
Stiffening plate makes it post and fix and connect with rear wall outer plate and back wall inner panel in the cavities, plays booster action, is greatly promoted
The torsion stiffness of vehicle body, optimizes the NVH performance of vehicle；And structure is simple, and it is solid and reliable, it is at low cost, it is easy to real in technique
It is existing, greatly improve the driving comfort sense of consumer.

Specific embodiment
It is such as involved to specific embodiment of the present utility model by the description to embodiment below against attached drawing
The shape of each component, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle etc. make
It is further to be described in detail.
Embodiment 1:
As shown in Figures 1 to 3, the back wall reinforcement structure of the utility model, including rear wall outer plate 1, back wall inner panel 2 and back wall connect
The two sides of fishplate bar 3, rear wall outer plate 1 and back wall inner panel 2 connect the cavity for forming inner transverse perforation by back wall connecting plate 3, close
Key is, further includes rear wall reinforcing plate 4, and rear wall reinforcing plate 4 is the box body structure of one side opening, including bottom surface and multiple sides；
The vertical two sides for being set to cavity of rear wall reinforcing plate 4, and welded by side and back wall inner panel 2 and rear wall outer plate 1.This back wall adds
Strong structure increases separately rear wall reinforcing plate 4 in the position that the two sides of cavity are equipped with back wall connecting plate 3, and rear wall reinforcing plate 4 is one side
The box body structure of opening, section be it is U-shaped, when installation, is disposed vertically, in order to which its side can be bonded rear wall outer plate 1 and back wall
