Problems solved by technology

[0002] Generally speaking, the existing bus body is mainly a steel structure body, which is welded by rectangular steel pipes. It has good bearing capacity, reliable structure, and low cost, but it is heavy in weight, and there are problems of corrosion and rust, which affect safety.
For this reason, a few passenger car factories in China have developed aluminum profile structure body, but it is generally welded by simply using rectangular aluminum tubes instead of the original rectangular steel tubes. Although this structure uses aluminum tubes that are lighter than steel tubes, the welding strength of aluminum welding There are great hidden dangers, the reliability of the body is not strong, and the deformation caused by aluminum welding is relatively large, and the manufacturing accuracy is not easy to control

Embodiment 1

[0022] A kind of body aluminum profile structure of this embodiment, such as figure 1 and figure 2 As shown, an outer surface of the aluminum profile 1 is provided with a groove composed of two U-shaped grooves 11 arranged side by side. The two sides of the U-shaped grooves 11 arranged side by side are respectively provided with outer grooves 12. The groove walls are respectively the groove bottom of the outer groove 12, and the aluminum profile 1 is a plane in the opening direction of the U-shaped groove 11. A screw hole 13 is provided on the groove wall of the U-shaped groove 11 . It also includes the plate 2 to be installed for connecting and fixing with the aluminum profile, the plate 2 to be installed is an aluminum profile, steel plate or aluminum plate, and the plate 2 to be installed is provided with a plug whose shape and quantity are all matched with the U-shaped groove 11. Sheet 21, inserting sheet 21 is provided with holes 22, inserting sheet 21 is inserted into...

Embodiment 2

[0025] A body aluminum profile structure of this embodiment is basically the same as that of Embodiment 1, the difference lies in: as image 3 and Figure 4 As shown, two U-shaped grooves 11 and outer grooves 12 arranged side by side are respectively arranged on different outer surfaces of the aluminum profile 1, so that the connection between a single aluminum profile 1 and multiple plates to be installed can be realized, and the aluminum profile 1 can be Single hole, also can be multi-hole.

Embodiment 3

[0027] A body aluminum profile structure of this embodiment is basically the same as that of Embodiment 1, the difference lies in: as Figure 5 and Figure 6 As shown, two U-shaped grooves 11 and outer grooves 12 arranged side by side are arranged on one or more outer surfaces of the aluminum profile 1, wherein at least one of the outer grooves 12 is a closed structure, and is connected with the aluminum profile 1. One outer surface forms a complete plane, which is convenient for installing other components and decorations such as other aluminum profiles, steel plates or aluminum plates on the aluminum profile 1, wherein the aluminum profile 1 can be single hole or porous.

Abstract

The invention discloses a vehicle body aluminum profile structure. A groove is formed in at least one external surface of an aluminum profile; outer grooves are formed on the two sides of the groove respectively; groove walls on the two sides of the groove are groove bottoms of the outer grooves; screw holes are formed in the groove walls of the groove; bolts are matched and fastened with nuts after penetrating through the groove through the screw holes; and heads of the bolts and the nuts are sunk in the outer grooves. According to the vehicle body aluminum profile structure, the groove is formed in the aluminum profile, and connected with the bolts and the nuts in a fastening manner, so that rigid connection of the aluminum profile is achieved; an aluminum welding technology is cancelled; the connecting strength and the manufacturing accuracy of a vehicle body structure constructed by the aluminum profile are ensured; the bolts and the nuts are sunk in the outer grooves after assembly; the maximum external surface of the aluminum profile is not protruded, so that mounting of inside and outside decorations and the like is not influenced; and other components such as other aluminum profiles, a steel plate or an aluminum plate can be mounted on the aluminum profile conveniently.

Description

technical field [0001] The invention relates to the field of motor vehicle body structures, in particular to an aluminum profile structure for a body. Background technique [0002] Generally speaking, the existing bus body is mainly a steel structure body, which is welded by rectangular steel pipes. It has good load-bearing capacity, reliable structure, and low cost, but it is heavy and has problems of corrosion and rust, which affects safety. For this reason, a few passenger car factories in China have developed aluminum profile structure body, but it is generally welded by simply using rectangular aluminum tubes instead of the original rectangular steel tubes. Although this structure uses aluminum tubes that are lighter than steel tubes, the welding strength of aluminum welding There are great hidden dangers, the reliability of the body is not strong, and the deformation caused by aluminum welding is relatively large, and the manufacturing precision is not easy to control....
