Description
Technical Field
[0001] The utility model relates to the field of pickup trucks, in particular to a side panel assembly of a pickup truck. Background Art
[0002] Among all types of automobile collision accidents, side collision accidents have the highest incidence rate, accounting for about 36% of the total number of automobile collision accidents. During a side collision, the energy absorption space of the vehicle side collision is small, resulting in serious injuries and mortality rates of up to 25% for occupants, of which 12% to 16% are caused by the side of the vehicle body hitting a column. When a vehicle collides with a rigid column, the contact surface of the column is small, and there is almost no deformable energy absorption space on the side of the vehicle body, resulting in a large degree of deformation of the vehicle body, and then a secondary collision occurs, posing a serious threat to the life safety of the occupants. Therefore, improving the column collision performance of the vehicle is very important to improving the safety of the entire vehicle.
[0003] C-NCAP pillar impact mainly compares and evaluates the damage values of the dummy's head, chest, abdomen and pelvis. For the body side, it mainly evaluates the intrusion of the B-pillar. At present, the pillar impact of new energy and hybrid vehicles has been included in the assessment items of C-NCAP, but non-load-bearing pickup trucks do not correspond to C-NCAP pillar impact. They score low in the C-NCAP pillar impact assessment and cannot meet the requirements of C-NCAP pillar impact performance.
[0004] The upper and lower joints of the A-pillar and B-pillar of the existing non-load-bearing pickup truck side structure are often weak, the door ring has no Y-axis support, and the Y-axis stability is poor. When the pillar hits, the front door ring and the door sill cannot resist the Y-axis deformation caused by the pillar hit, which poses a great threat to the safety of the passengers. In order to improve its pillar impact performance, the existing methods usually increase the material thickness of the side pillar and the door sill, or install an aluminum alloy integral energy absorption structure in the door sill cavity, but the cost of these two solutions is often high, and the increase in the thickness of the sheet metal will greatly increase the total weight of the side, which will increase the weight of the vehicle, further leading to increased fuel consumption or power consumption, and reducing product competitiveness.
