Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
In this disclosure, unless otherwise indicated, the use of directional terms such as "upper, lower, left, and right" generally refer to the reference definition of the orientation of the corresponding drawing figures, "inner and outer" refer to the inner and outer of the contour of the corresponding element, and "distal and proximal" refer to the distance of the corresponding structure or corresponding element from another structure or element. In addition, it should be noted that terms such as "first, second", etc. are used to distinguish one element from another element without order or importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings denote the same elements.
In the related art, the scheme of the conventional vehicle type is that a cavity is formed by a C-pillar lower inner plate, a front C-pillar lower inner plate and a rear C-pillar lower inner plate, and extends upwards to a lower plate of a retractor to be butted with a front cross beam of a hat rack. The Y-direction supporting height of the type is low, the structure of the upper side beam is difficult to effectively support, and the Z-direction height is limited by the installation of a retractor and cannot be adjusted; the C column lower inner plate-front and C column lower inner plates-rear form a cavity Y-direction and X-direction to occupy larger space, and the weight is heavier; the lower inner plate of the C column, the lower outer plate of the C column at the front and the outer side, is only connected with a small section of flanging, and the transmission efficiency is lower. The support of the retractor upper plate and the lateral structure, although relatively high, is only supported on a thinner inner plate, not on the force transmission path, and the contribution is very limited. On an integrated arrangement, the side-end retractor, harness, trim, etc. mounting assemblies are all far apart, occupy a large amount of space, and break the structural continuity of the transverse primary transfer path.
From the above, the upper and lower transition of the rear side end structure of the current main stream vehicle model is weaker, and the rigidity and strength of the current main stream vehicle model are insufficient; the device is isolated from the transverse structure, is connected only through a limited support at the lower part, has a bulky structure and lower transmission efficiency; the upper parts of a small number of vehicle types are occasionally supported and are not built on an effective force transmission path, so that the effect is poor. And each installation component is scattered, more space in the vehicle is occupied, and the integration level is low.
According to the technical scheme, through constructing complete multipath longitudinal, vertical, transverse and joint structures, more modules and installation components are integrated simultaneously, so that the efficient utilization of structural space is realized, and the dynamic and static rigidity and the safety strength of the whole vehicle are greatly improved.
