Problems solved by technology
However, the current commonly used connection methods between aluminum profiles are MIG welding and riveting. During MIG welding, the deformation of the parts is large and the accuracy is difficult to guarantee. However, due to the large space and heavy weight of the riveting equipment during riveting, there are many problems in the connection between profiles. Large limitations, insufficient structural space often lead to riveting process can not be realized

The invention discloses a connector suitable for connection among a vehicle body cross beam, a side wall plate and a threshold beam, which is connected to the joint among the vehicle body cross beam,the side wall plate and the threshold beam, and comprises a main fixed seat plate and a fixed support frame, a tail connecting plate is arranged on the upper side of the tail of the threshold beam; alower side plate body of the side coaming is fixedly connected with a tail connecting plate of a threshold beam, the main fixing base plate is fixedly connected with the side coaming, the fixing supporting frame is of a door-shaped frame structure and comprises a transverse plate and supporting plates located on the two sides of the transverse plate, and the ends of the supporting plates are perpendicularly and fixedly connected to a plate body of the main fixing base plate. And the end part of the cross beam is fixedly connected with the fixed support frame. The connector suitable for connection among the vehicle body cross beam, the side coaming and the threshold beam has high bending resistance and torsion resistance, can improve rigidity, meet the performance requirement of a vehicle body structure and reduce manufacturing cost, and is simple in connection process, high in connection reliability and high in practicability.
Description
technical field [0001] The invention relates to a connector suitable for the connection between a vehicle body cross beam, a side panel and a door sill beam, and relates to the technical field of assembly of auto parts. Background technique [0002] Aluminum has the advantages of low density and light weight. From the perspective of light weight, aluminum is a relatively high-quality material, but the parts formed by aluminum plate have high mold cost during manufacture, difficult forming, and the strength and rigidity are not as good as steel parts. The parts of the aluminum profile structure have sufficient strength and rigidity, and are extruded with equal cross-sections during manufacture, so the manufacturing cost is low, so aluminum often appears on the body in the form of profiles. However, the current commonly used connection methods between aluminum profiles are MIG welding and riveting. During MIG welding, the deformation of the parts is large and the accuracy is ...
