Description
Technical field
The present invention relates to technical field of vehicle, more particularly to a kind of vehicle body plant-on component sealing structure.The invention further relates to
A kind of manufacture method of the vehicle body plant-on component sealing structure, and a kind of car for being provided with the vehicle body plant-on component sealing structure
Body gusset lower-edge beam and the vehicle for being equipped with the body side wall lower-edge beam.
Background technology
In Car design, good body structure can not only ensure the security performance and rigidity and intensity of vehicle, and
The weight of vehicle, and arrangement of the design with rubber alloy class auxiliary material of body structure are reduced, aesthetic is also can reach, can be lifted
The exquisite sense of vehicle.
In existing vehicle structure, a kind of structure of body side wall bottom as shown in Figure 1 to Figure 3, in the structure shown here in side
Enclose between outside plate and threshold reinforcing plate, and two sections of commissures between threshold reinforcing plate, threshold internal plate and floor side side bar apply
Fluid sealant 6 is broken, now to avoid the exposed influence of the fluid sealant 6 of commissure between side-wall outer-plate and threshold reinforcing plate attractive in appearance, is generally needed
Lower-edge beam backplate 5 is designed to be covered to fluid sealant 6, but the setting of lower-edge beam backplate 5 not only increases a kind of parts
Exploitation manufacture, the input of the standard components such as increase installation buckle and other auxiliaries is also needed, so as to which logistics and installation beat can be increased,
It is unfavorable for the light-weighted design of vehicle.
Another structure of existing body side wall bottom as shown in Figures 4 and 5, only need to be outside gusset in this kind of structure
Commissure between plate 4, threshold reinforcing plate 1 and floor side side bar 3, which applies, breaks one section of fluid sealant 6, but side-wall outer-plate 4 is strengthened with threshold
A kind of relatively upper structure of the structural cavities formed between plate 1, which can increase, to be twice, and can cause the material usage of side-wall outer-plate 4 replies to increase
Add, and it is equally also unfavorable for the lightweight of vehicle.
