the threshold assembly provided in the embodiment of the application, the threshold assembly includes: a rocker inner panel 1, a bumper beam 22, and a plurality of support portions 21; the supporting parts 21 are all arranged on the surface of the inner sill plate 1 and are sequentially arranged at intervals along the horizontal direction, and the buffer beams 22 are positioned on the top surfaces of the supporting parts 21, namely the surface of one side away from the inner sill plate 1 and are fixedly connected to each supporting part 21; the plurality of support portions 21 are dispersed and support the bumper beams 22 at intervals.

Through using the supporting part 21 that a plurality of intervals set up to cushion the buffer beam 22, the buffer beam 22 is located the part between two adjacent supporting parts 21 and unsettled, and when the vehicle had the collision accident, the unsettled part of buffer beam 22 can play great cushioning effect, improves the security, reduces the harm to the person. The structure is simple, and the manufacturing difficulty is low.

In order to further improve the cushioning capacity of the rocker assembly, each support portion 21 is made of a hollow structure, and the support portion 2 may be made of a hollow shell shape having an opening toward the rocker inner panel 1, and the opening edge of the hollow shell is fixedly connected to the rocker inner panel 1. When the vehicle collides, the hollow structure of the supporting portion 21 is damaged by the collision, and the hollow structure is deformed during the collision, thereby playing a role of cushioning.

The opening edge of each supporting portion 21 is provided with an extension wall 211, the extension wall 211 extends along the opening edge of the corresponding supporting portion 21 and is attached to the surface of the inner threshold plate 1, the extension wall 211 is fixed on the inner threshold plate 1 by spot welding, the positions of the welding spots can refer to the positions marked by each M in fig. 3, only part of the welding spots M are shown in the drawings, the number of the welding spots M is a plurality, and the welding spots M are distributed at intervals due to the extension wall 211, so that the plate-shaped extension wall 211 and the inner threshold plate 1 are prevented from being burnt out, and the extension wall 211 and the inner threshold plate 1 are fixedly connected in a relatively convenient manner; and the overall strength of the side door threshold of the vehicle body can be effectively improved. However, the outer extension wall 211 and the rocker inner panel 1 can be fixedly connected by bolts penetrating therethrough, which facilitates the disassembly and replacement of the support portion 21.

In a specific embodiment, the bumper beam 22 is a hollow beam, and a hollow space is formed inside the hollow beam, so that the bumper beam 22 is beneficial to deformation when a vehicle collides, so that the bumper beam 22 has excessive strength and cannot play a role in buffering. Meanwhile, the portion of the rocker 22 located between the two support portions 21 is more likely to be folded inward in the direction of the rocker inner panel 1 by the impact to play a role of cushioning.

Wherein, when welding the bumper beam 22 and the support portions 21, the bumper beam 22 may be fixed to each support portion 21 by carbon dioxide arc welding. Thereby, the fixing strength between the bumper beam 22 and the supporting portion 21 is facilitated to be improved, and at the same time, the assembling step is facilitated to be simplified; and the overall strength of the side door threshold of the vehicle body can be effectively improved. However, the bumper beam 22 and the support portion 21 may be fixedly connected by bolts or the like to facilitate disassembly and replacement.

In a specific embodiment, the surface of each support portion 21 facing away from the rocker inner panel 1 is a mounting plane P, which may be perpendicular to the ground in particular, but the actual angle may be determined according to the vehicle body front structure; the cross-sectional outer profile of the bumper beam 22 may be rectangular, and one side of the rectangle is attached to and fixedly connected with the mounting plane P, so as to increase the contact area, thereby facilitating improvement of the fixing strength. The buffer beam 22 with the rectangular section is regular in shape and convenient to manufacture and transport, and meanwhile, the surface of the buffer beam 22, which faces away from the supporting part 21, has a larger bearing area, so that impact force can be dispersed into smaller pressure during impact, and the deformation of the buffer beam 22 is reduced as much as possible.

The bumper beam 22 may be an aluminum profile, and the aluminum profile may be a standard profile, which is beneficial to reducing development cost and difficulty in acquiring parts. And moreover, the aluminum profile has better structural strength, and the strength of the car body threshold structure can be improved.

In addition, the rocker assembly may further include a rocker outer panel 3 disposed opposite to the rocker inner panel 1, the rocker outer panel 3 and the rocker inner panel 1 being matched with each other to form a cushioning space U surrounding the cushioning beam 22 and the plurality of support portions 21, the cushioning space U providing a cushioning margin for the rocker outer panel 3 when an impact occurs, so as to improve a cushioning effect. When the rocker outer panel 3 is deformed sufficiently, it is not hit against the bumper beam 22 and the plurality of support portions 21 located in the bumper space U. The above structure improves the buffering effect.

The buffer beam 22 can adopt a regular hexagon, a triangle, a trapezoid and other special-shaped cross sections besides a rectangular cross section; the material can be composite material, nonmetal and other metals, such as steel, etc. Based on the same inventive concept, the embodiment of the present application also provides a vehicle body including the rocker assembly provided in the above embodiment.
