Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments described in the utility model, for those of ordinary skill in the art, is not making the creative labor
Under the premise of, other drawings may also be obtained based on these drawings.
Fig. 1 is the stereoscopic schematic diagram of one specific implementation mode of automobile rear wall inner panel of the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model provides a kind of automobile rear wall inner panel, the automobile rear wall inner panel includes：Plate body 1,
It is set to boss 2, location hole 3 and welding convex surface on the plate body 1.Preferably, the boss 2, location hole 3 and welding
Convex surface is integrally formed by impact style.
The plate body 1 is bar shaped, with front and back.Wherein, the front forms welding surface, and the back side is formed and vehicle
The fitting surface of rear wall outer plate.In order to enable plate body 1 has higher intensity, and carries out being thinned for thickness, the plate body 1 is using in the wrong
Take the steel of intensity 1300MPa or more.
Further, the plate body 1 is also carried out such as lower structure improvement：The top edge recess setting of the plate body 1, which is formed, to keep away
Allow space.Meanwhile the top edge of the plate body 1 is provided with flange 11, the flange 11 and the plate body 1 are perpendicular and described
