Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention will be further described as follows:

[0026] As shown in the accompanying drawings, the present invention provides an improved profile internal local reinforcement structure, including a reinforcement 1 and a profile body 2. A reinforcement 1 is pressed into the cavity. The reinforcement 1 is a block structure. The reinforcement 1 is used to locally strengthen the profile body 2. The shape of the reinforcement 1 is connected with the inner cavity of the profile body 2. The surface of the reinforcement 1 is provided with interference ribs. 11. The interfering ribs 11 are in a convex shape, and the interfering ribs 11 are against the inner wall of the cavity of the profile body 2, and are attached and connected with the inner wall of the cavity of the profile body 2. Wherein, the left and right sides of the reinforcement 1 are attached to the inner wall of the cavity of the profile body 2, that is, th...

Abstract

The invention relates to the technical field of automobile parts, in particular to an improved section bar internal local reinforcing structure for an automobile body structure. The structure comprises a reinforcer and a profile body, wherein the section of the profile body is of a trapezoidal structure; a trapezoidal cavity is formed in the profile body; the reinforcer is pressed into the trapezoidal cavity, is of a blocky structure and is used for locally reinforcing the profile body, the shape of the reinforcer is connected with the inner cavity of the profile body in a matched mode, and interference ribs are arranged on the surface of the reinforcer, abut against the inner wall of the cavity of the profile body and are connected with the inner wall of the cavity of the profile body inan attached mode. Compared with the prior art, local reinforcement can be carried out on any position of the inner cavity of the profile body, traditional reinforcement schemes such as manufacturing athrough rib structure and changing a high-performance material are abandoned, the weight of profile parts is greatly reduced, the cost is reduced, the material utilization rate is increased, and thepurpose of light weight is achieved.

Description

[technical field] [0001] The invention relates to the technical field of auto parts, in particular to an improved profile inner local reinforcement structure for the structure of an automobile body. [Background technique] [0002] At present, in the design of automobile body structure, due to the consideration of lightweight, more and more aluminum alloy profiles are used instead of steel plates as the main load-bearing structural parts. During the use of the profile, it also assumes the role of overlapping with the surrounding structure and local installation points. Therefore, if there is a rigidity or strength requirement on the part of the profile, it is necessary to strengthen the part of the profile, especially the strengthening of the inner cavity is a technical problem. In the prior art, the following three methods are mainly used for local strengthening of the profile cavity: [0003] (1) The method of increasing the wall thickness of the profile in the existing s...
