Detailed Description

The following describes the embodiments of the present invention in detail. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.

The utility model discloses in provide a B post reinforcing plate structure, as shown in fig. 1-5, this B post reinforcing plate structure includes the reinforcing plate body, the reinforcing plate body includes well upper segment part and hypomere part, the hypomere part is provided with and is used for making the hypomere part is compared when the collision the weakening structure that well upper segment part takes place to warp more easily.

The present B-pillar reinforcement structure is located at the middle position of the side surface of the automobile, and since the lower section portion is provided with a weakening structure for making the lower section portion more easily deformed than the middle-upper section portion at the time of collision, the lower section portion is more easily deformed to absorb energy generated by collision at the time of collision of the side surface of the automobile. The reason for this is that: the lower segment corresponds to a relatively unimportant part (leg or foot) of a human body, so that the important part of the human body is protected in a mode of ensuring that the upper segment is less deformed in the collision process by sacrificing the deformation of the lower segment, and the effect of protecting passengers is achieved.

Preferably, the weakening structure comprises an induced deformation zone provided on the lower section portion to concentrate the weakening in the induced deformation zone. Wherein, the form of the induced deformation region may be set as required as long as the lower segment portion can be weakened. Preferably, the deformation-inducing region may include an inducing rib. The inducing ribs may be positioned, configured and numbered according to the desired deformation. Preferably, the induced muscle includes induced muscle 201, middle induced muscle 202 and lower induced muscle 203 on, go up induced muscle 201 with induced muscle 203 transversely sets up from top to bottom down, preferably, go up induced muscle 201 with induced muscle 203 parallel arrangement down, middle induced muscle 202 through connection in go up induced muscle 201 with induced muscle 2 down. Thus, when the B-pillar reinforcing structure on the side surface of the automobile is impacted, the lower section part can be sunken or even broken based on the arrangement of the induced deformation area, and in the process, the energy generated by the impact is absorbed.

Further preferably, the upper induced rib 201, the middle induced rib 202 and the lower induced rib 203 form the induced deformation region in an i shape. This ensures that plastic deformation occurs more readily during a crash to absorb energy.

In addition, preferably, the inducing rib is a concave rib to facilitate the weakening.

In order to enable the side face of the automobile to be easier to generate plastic deformation to absorb energy when the automobile is collided, the middle area of the B-pillar reinforcing plate structure is ensured to have smaller deformation in the collision process, and the area structure weakening is realized. The weakening structure comprises a collapsing hole arranged on the lower section part.

In order to make the deformation of the B-pillar reinforcement plate structure uniform, the collapse holes include a first collapse hole 204 and a second collapse hole 205 respectively disposed at both sides of the middle induction rib 202.

Further preferably, the first collapse holes 204 and the second collapse holes 205 are located between the upper induction rib 201 and the lower induction rib 203 to enhance the weakening effect.
