Background
Nowadays, the requirements of people on automobiles tend to be higher and higher in performance, lower in pollution, lower in energy consumption and the like. There are two main ways for reducing energy consumption of automobiles: firstly, improving a dynamic system; and secondly, the weight of the automobile is reduced, namely the automobile is lightened. In order to meet the design requirement of light weight of the automobile body, the most promising approach is to change light materials to manufacture automobile parts. Since the 70's of the 20 th century, there was an emergence of alternatives to steel plate castings. The automotive industry at that time found that die castings were placed in the most important locations among the various aluminum alloy castings. Therefore, the aluminum alloy die casting is adopted as an important part of an automobile, the part with the most aluminum alloy die casting process is used as a front shock absorption tower in the automobile body part, and the weight reduction effect is about 30%. The current pickup trucks have a tendency to switch from fuel vehicles to new energy vehicles. Due to the need for the development of electric vehicles, it is important to reduce the weight of the vehicle body.
In the prior art, the body of a pickup truck consists of a frame, a cab and a container, is made of low-carbon steel and high-strength steel materials, and is formed by welding an inner plate and an outer plate. The cab and the container are mounted on the frame through suspension, the force transmission paths of the traditional pick-up truck are 2 in the upper direction and the lower direction, the frame is a main force transmission path, the cab is an auxiliary force transmission path, the whole truck is small in collision contribution, the container is an independent part, the collision contribution is extremely small, the container is not included in the force transmission path, and the body of the traditional pick-up truck adopts an inner plate and outer plate welded form to form a body cavity so as to achieve the necessary rigidity effect of the body. The existing body structure of the pickup truck has the following defects:
the first disadvantage is that: the independent frame, the container and the cab are connected with each other through the vehicle body in a suspension manner, so that the vehicle has poor stability and high cost;
the second disadvantage is that: the integration level of the vehicle body structure is insufficient, the number of parts is large (about 600 parts), the parts need to be welded, about 4000 welding points are needed for the whole vehicle, the number of welding procedures is large, the welding procedures are complex, and the efficiency is low;
