Background technology
Automobile bodies are provided at automotive back includes base plate, framework and five pieces for containing the casing of goods, automobile bodies
Boxboard, three is collectively forming a rectangular-shape closed cavity for holding freight, and wherein base plate is located at the bottom of framework, five pieces of casees
Plate originally not Wei Yu framework four sides and top.
In existing automobile bodies, base plate, framework and boxboard are generally all solid steel plate or steel frame, the group of framework
The connected mode of the connection, boxboard and framework of dress, base plate and framework all uses riveting, after whole compartment is completed, the bottom of then at
Plate lower end rivets the spandrel girder of steel, for supporting whole compartment.However, above-mentioned existing carriage body construction has the following disadvantages:
1st, steel plate or steel frame are too heavy, increased the burden of automobile, can not meet the demand now to automotive light weight technology,
And if to mitigate the weight in whole compartment, only reduce its size, but the intensity in so whole compartment does not reach requirement again, especially
It is the base plate and framework for playing load-bearing, supporting role.
2nd, spandrel girder and base plate are connected by the way of riveting, when automobile is subject to larger vibration, base plate and spandrel girder
Between be susceptible to displacement, cause to connect unstable between base plate and spandrel girder, i.e., whole compartment connection is unstable;
3rd, boxboard above plays a part of to keep out wind and rain for whole compartment, it is to avoid the goods of interior because
Exposure to Sunlight drenches with rain and damages, however, whole compartment is in assembling, all using riveting, riveting can form seam to all of connected mode
Gap, for the connection between boxboard and framework above, on rainy day, rainwater rivets gap and enters easily by it
Enter to interior, although speed is relatively direct to drench with rain more slow, but the time is long long afterwards or can be complete by goods therein
Soak, cause cargo damage.In order to solve the problem, some technical staff can smear some glue in gap is riveted, to rise
To the effect of waterproof, but by after rainwash, glue easily comes off, the effect of waterproof is not still had.
