The arched support part 20 makes full use of the limit of the vehicle body to improve the cargo space in the vehicle, the horizontal section of the support top part 202 of the support part 20 is approximately equal to the width of the roof 10 of the vehicle body, and the transition section is matched with the inner side surface of the upper end of the vehicle door.
The support portion 20 specifically includes a groove-shaped main body, the notch faces the inside, and the groove-shaped main body is a metal member, such as a steel structure 201 c. The groove type main part can be the integral type structure, also can divide the body structure, for example the groove type main part can include monoblock arch curb plate, monoblock arch front end plate, monoblock arch rear end plate, then the three is spliced together again, and the transversal profile of formation is the cell type.
At this time, the support portion 20 further includes a non-metal plate 201e and a metal plate, the metal plate may be a steel plate, the non-metal plate 201e may be made of, for example, a thermoplastic glass fiber reinforced material, the non-metal plate 201e covers the notch portion of the trough-shaped main body located at the arched top corner, and the metal plate covers the rest of the notch portion, thereby forming the support portion 20 of the box-shaped structure. As shown in fig. 6, through test and simulation analysis, the bearing requirement of the vertex angle position is small, the strength requirement can be met by arranging the non-metal plate 201e, and the purpose of reducing weight can be achieved, on the other hand, the non-metal plate 201e and the groove-shaped main body do not need to be welded and fixed, and can be fastened through a fastener, so that the non-metal plate 201e and the groove-shaped main body can be conveniently detached and opened, and the internal mechanism can be overhauled, replaced and the like, for example, the middle transmission mechanism 503 of the vehicle door opening and closing mechanism, wherein the fastener can be a rivet, and certainly can. The other positions of the supporting portion 20 need stronger bearing capacity, so a metal plate is added to improve the local strength. The lower part of the supporting upright 201 belongs to the position with concentrated stress, especially the position connected with the bottom frame 30, and a thicker metal plate can be sealed to improve the local strength in a targeted way.
