Abstract

The invention proposes a connecting structure of a vehicle back floor cross beam and longitudinal beams. The connecting structure comprises the back floor cross beam and two back floor longitudinal beams; the two back floor longitudinal beams are fixedly connected with the back floor cross beam through connecting brackets; the connecting brackets include connecting plates as support bodies; connecting plate surfaces are arranged at the front ends of the connecting plates for gluing with the back floor cross beam; multiple connecting parts are formed on the back surfaces of the connecting plates; and the connecting parts are glued with the back floor longitudinal beams. The unique structure design of the connecting brackets realizes large-area gluing of the front ends of the connecting brackets and the back floor cross beam and one-way and two-side connection of the back ends of the connecting brackets and the back floor longitudinal beams so as to realize connection of profile cross beams and longitudinal beams and guarantee the connecting reliability; aluminum alloy profiles with better rigidity and strength are adopted; profile molds are lower in cost; and the production efficiency is high. As a structural glue bonding process is adopted, the strength of a gluing area is not influenced, the self manufacturing errors of parts and assembly errors among the parts can be eliminated, and the manufacturing precision is improved.

Description

technical field [0001] The invention relates to a connection structure between auto parts, in particular to a connection structure between a rear floor beam and a longitudinal beam of an automobile. Background technique [0002] As the all-aluminum body technology is becoming more and more popular in the market, the connection between the floor longitudinal beam and the beam of the all-aluminum body model mainly includes two connection methods: the overlapping of aluminum sheet stamping parts or the overlapping of profile parts and cast aluminum parts. The way in which the stamped parts of aluminum plate are overlapped with each other, the main parts in this combination method are all stamped and formed, and the longitudinal beams and beams are connected by spot welding, welding or riveting of the parts. As for the overlapping connection of profile parts and cast aluminum parts, the beam is a profile part and the rear longitudinal beam of the floor is a cast aluminum part in...
