Problems solved by technology

This structure has good rigidity and can withstand large side impacts, but before the side wall structure of the body is connected to the body, its rigidity and strength are poor due to the lack of support of the sill structure, resulting in some precision and quality in the production process question

Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention will be further described as follows:

[0025] as attached figure 1 And attached figure 2 As shown, the present invention provides an improved automobile door sill structure, which includes a door sill outer panel 1 and a door sill inner panel 2. The door sill outer panel 1 is a stamping part made of steel or aluminum, and the cross section of the door sill outer panel 1 is C-shaped. Type, the upper and lower ends of the sill outer panel 1 are extended with a flange surface 11 along the vertical direction, the sill inner panel 2 is an extruded profile made of aluminum, the cross section of the sill inner panel 2 is square, and the sill inner panel 2 Divided into at least two cavity structures, the upper and lower ends of the threshold inner panel 2 are extended along the vertical direction with flange surface 2 21, flange surface 11 is connected with flange surface 2 21, and the threshold outer pane...

Abstract

The invention relates to an improved automobile threshold structure. The improved automobile threshold structure comprises a doorsill outer side plate and a doorsill inner side plate, the doorsill outer side plate is a stamping part made of steel or aluminum. The section of the doorsill outer side plate is C-shaped; and the upper end and the lower end of the threshold outer side plate extend in the vertical direction to form first flange faces. The doorsill inner side plate is an extruded section made of aluminum; the section of the threshold inner side plate is square, the interior of the threshold inner side plate is divided into at least two cavity structures, the upper end and the lower end of the threshold inner side plate extend in the vertical direction to form second flange faces,the first flange faces and the second flange faces are connected in a matched mode, and the threshold outer side plate and the threshold inner side plate are oppositely arranged and fixedly connectedto form a cavity structure. Compared with the prior art, the doorsill outer side plate can be placed into the vehicle body side wall structure, so that the side wall structure has good rigidity and strength, some unnecessary precision and quality problems cannot be generated, and the doorsill inner side plate structure is provided with a plurality of cavity structures, is high in rigidity and goodin energy absorption effect and can bear large side impact.

Description

[technical field] [0001] The invention relates to the technical field of automobile spare parts, in particular to an improved automobile door sill structure for vehicle bodies. [Background technique] [0002] In a four-wheeled passenger car, the body structure usually has a sill structure connecting the body floor and the side wall of the body, which is an important part of the load-bearing frame of the body. When a car suffers a frontal or side impact, the huge impact energy will be dispersed to other parts of the body through the sill structure, so it plays a vital role in the overall safety performance of the car. At the same time, its weight also occupies a relatively large proportion in the total weight of the vehicle body. Therefore, a sill structure with high strength and light weight can directly enhance the competitiveness of the vehicle in the market. [0003] In the prior art, the structure of the threshold mainly has the following two types: [0004] (1) The t...
