The utility model provides a longeron bottom plate behind automobile body has better buffering effect, has improved the resistance to compression and the ability of anti striking of back longeron bottom plate effectively to the life of back longeron bottom plate has been improved.
Description
Technical Field
The utility model relates to an automobile body technical field specifically relates to an automobile body back longeron bottom plate with buffer function.
Background
With the development of the automobile industry, the safety performance of automobiles is more and more concerned by people and is an index for measuring the comprehensive performance of one automobile, for passive safety, the size and the direction of the crumple deformation of the automobile body are important factors influencing the safety of passengers, and in automobile collision, the safety of people in the automobile is important to protect.
The existing automobile body rear longitudinal beam bottom plate has weak pressure resistance and poor buffering effect, so that the rear longitudinal beam bottom plate is easy to damage or deform and crack when bearing large pressure or collision force, the rear longitudinal beam bottom plate loses the effect, and the service life of the rear longitudinal beam bottom plate is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving one of the technical problem that exists among the prior art at least. Therefore, the utility model provides a longeron bottom plate behind automobile body with buffer function, include:
the rear longitudinal beam bottom plate comprises a rear longitudinal beam bottom plate body (1), wherein a first bending plate (2) is arranged at the top of the rear longitudinal beam bottom plate body (1), a second bending plate (4) is arranged on the first bending plate (2), and a third bending plate (3) is arranged on one side of the rear longitudinal beam bottom plate body (1);
the elastic buffer part is arranged inside the rear longitudinal beam bottom plate body (1) and comprises an elastic sheet (5).
Furthermore, shell fragment (5) are wavy, shell fragment (5) are a plurality of, a plurality of shell fragment (5) set up parallelly in the inside of back longeron bottom plate body (1).
Furthermore, the rear longitudinal beam bottom plate comprises elastic filling bodies (6), wherein the elastic filling bodies (6) are filled between two adjacent elastic sheets (5) and between the elastic sheets (5) and the inner wall of the rear longitudinal beam bottom plate body (1).
Furthermore, the rear longitudinal beam bottom plate comprises elastic pads (7), wherein the elastic pads (7) are arranged between the two elastic sheets (5) at intervals and between the elastic sheets (5) and the inner wall of the rear longitudinal beam bottom plate body (1).
Further, the elastic filling body (6) and the elastic cushion (7) are made of rubber.
The utility model provides a longeron bottom plate behind automobile body has better buffering effect, has improved the resistance to compression and the ability of anti striking of back longeron bottom plate effectively to the life of back longeron bottom plate has been improved. When the rear longitudinal beam bottom plate body is subjected to larger pressure or impact force, the pressure or impact force applied to the rear longitudinal beam bottom plate body is transmitted to the elastic sheet and the elastic filling body or the elastic pad, and the elastic sheet and the elastic filling body or the elastic pad slow down the deformation of the rear longitudinal beam bottom plate body relatively.
