Problems solved by technology

At present, the welding process is generally used for the connection of aluminum profiles, but the deformation of aluminum welding is large, the precision is not easy to control, and there is a great hidden danger in the strength, which affects the appearance of the whole vehicle, and it is difficult to meet the design and performance requirements, especially for special-shaped aluminum profiles. The irregular shape makes the welding more difficult to control and the strength is more affected

Embodiment 1

[0018] A connection structure of special-shaped aluminum profiles in this embodiment, such as figure 1 and figure 2 As shown, it includes two special-shaped aluminum profiles 1 connected in parallel. The special-shaped aluminum profile 1 includes a groove structure composed of two U-shaped grooves 11 arranged side by side. An outer groove 12 is respectively provided on both sides of the groove structure. The groove walls on both sides of the groove structure are respectively the groove bottom of the outer groove 12, and a plurality of screw holes 13 are opened on the groove wall of the groove structure, and the outer groove 12 of one of them is a closed structure, and is connected with the special-shaped aluminum profile 1 One outer surface forms a complete plane, and bolt through holes 14 corresponding to the screw holes 13 are opened on the plane. Reinforced aluminum plates 2 are respectively inserted in the mutually parallel U-shaped grooves 11 between the two special-sha...

Embodiment 2

[0022] A connection structure of special-shaped aluminum profiles in this embodiment, such as image 3 and Figure 4 As shown, it includes two vertically connected special-shaped aluminum profiles 1. The special-shaped aluminum profile 1 includes a groove structure composed of two U-shaped grooves 11 arranged side by side. The two sides of the groove structure are respectively provided with outer grooves 12. The grooves The groove walls on both sides of the structure are respectively the groove bottom of the outer groove 12, and a plurality of screw holes (not shown in the figure) are opened on the groove wall of the groove structure, and the outer groove 12 of one of them is a closed structure, and is connected with An outer surface of the special-shaped aluminum profile 1 forms a complete plane, and a bolt through hole 14 corresponding to the screw hole is opened on the plane. Connecting aluminum plates 5 with right angles are respectively inserted in the mutually perpendic...

Abstract

The invention discloses a connecting structure of special aluminum profiles, which comprises a parallel connection mode and a vertical connection mode, wherein the parallel connection mode comprises reinforcing aluminum plates and nut steel sheets; rigid connection is achieved through threaded connection among the reinforcing aluminum plates and the special aluminum profiles; the vertical connection mode comprises connecting aluminum plates and nut steel sheets; and rigid connection is achieved through threaded connection among the connecting aluminum plates and the special aluminum profiles. The connecting structure of the special aluminum profiles utilizes the reinforcing aluminum plates or the connecting aluminum plates to substitute an aluminum welding procedure used for connection between the traditional special aluminum profiles, solves the problems of structure deformation and insufficient strength due to the aluminum welding procedure, and ensures the firmness and the reliability of the connection between the special aluminum profiles; the connection accuracy can be controlled easily; bolts and the nut steel sheets are sunk into external slots, and the maximum external surfaces of the special aluminum profiles are not protruded, so that the complete vehicle design and performance requirements of a motor vehicle are met; and the quality of the complete vehicle is improved.

Description

technical field [0001] The invention belongs to the field of frame connection structures of motor vehicle bodies, in particular to a connection structure of special-shaped aluminum profiles of frame frames of automobile bodies. Background technique [0002] At present, energy saving, environmental protection and the development of low-carbon economy have become the main theme of the world. In the field of automobiles, in addition to improving the power system and using clean energy, the lightweight of automobiles is a more effective and easier way to save energy and reduce CO2 emissions. In order to reduce the weight of the car, it is necessary to use suitable lightweight materials to replace the commonly used heavy steel materials. Among many materials, aluminum and aluminum alloy profiles have the advantages of light weight, excellent formability, high strength, and corrosion resistance. Profiles can be widely used in the automotive field. At present, the welding process ...
