Abstract
The utility model provides a bonded construction for the back of the mini-car bodywork, comprising a rear frame member for the top cover and a side wall. The rear upper part of the side wall is directly connected with the rear frame member of the top cover. As per the above solution, this utility model simplifies the bonded construction for the back of the mini-bodywork and lowers the matching difficulty of the spare parts as well as removes the water leakage so as to increase the structural stiffness, lower the welding cost and improve the bodywork quality. When the bonded construction is close to the rear side wall, the utilization ratio of the stretching sheet material for the side wall is improved.
Description
Technical field
The utility model relates to the structure of little car vehicle body upper back, relates in particular to the bridging arrangement of a kind of little car vehicle body upper back.
Background technology
Mid-get car refers generally to the automobile of free air capacity below 1 liter, comprises baby car, microvan (utility van) and minitruck.Little car has become the fastest industry of domestic automobile rate of industrial development.Because little car vehicle body is higher, gusset rear portion and top cover after cross member generally all overlap by connecting panel, as shown in Figure 1, gusset rear portion 102 and connecting panel 103 need to be welded into gusset branch unit (being the gusset subsystem) on special frock clamp, by total station of piecing together, gusset subsystem and the top cover after cross member 101 that combines connecting panel welded again.
Because this zone is positioned at the corner, complex structure, the profile of connecting panel difficult with and the 102 fine applyings of gusset rear portion, part locate also difficulty, the therefore shortcoming that exists tail-gate to intake easily on frock.And, owing to a plurality of parts on the corner overlap, thereby cause landing edge to interfere easily, buckling deformation causes tail-gate adhesive tape card not tight, also is the principal element of leaking.And, often cooperate badly because of part overlap joint, influenced the presentation quality of vehicle body.
Therefore, there is defective in prior art, needs to improve.
The utility model content
The purpose of this utility model is to provide the bridging arrangement of a kind of little car vehicle body upper back, and complex structure, tool locating difficulty, the landing edge that is used to overcome existing bridging arrangement interfered, buckling deformation causes the shortcoming of leaking.
The technical solution of the utility model is as follows:
The bridging arrangement of a kind of little car vehicle body upper back, it comprises top cover after cross member and gusset, the upper back of described gusset and described top cover after cross member direct connection.
The bridging arrangement of described little car vehicle body upper back, wherein, the connecting portion of the connecting portion of the upper back of described gusset and described top cover after cross member is mutual adaptive structure.
The bridging arrangement of described little car vehicle body upper back, wherein, the connecting portion of the connecting portion of the upper back of described gusset and described top cover after cross member is the structure of mutual close fit.
The bridging arrangement of described little car vehicle body upper back, wherein, the center at described direct coupled position is shorter than distance with described top cover after cross member with the distance of the upper back of described gusset.
The bridging arrangement of described little car vehicle body upper back, wherein, the center at described direct coupled position is arranged on the top, upper back of described gusset.
Adopt such scheme, the utility model has been simplified the bridging arrangement of little car vehicle body upper back, has reduced the parts match difficulty, has eliminated the risk of leaking, and has improved the rigidity of structure, has also reduced welding cost simultaneously, has improved body quality; When bridging arrangement is provided with near the back gusset, also promoted the sheet material degree of utilization of gusset drawing and forming.
Description of drawings
Fig. 1 is that the bridging arrangement of prior art is realized scheme drawing;
Fig. 2 is that bridging arrangement of the present utility model is realized scheme drawing.
The specific embodiment
Below preferred embodiment of the present utility model is described in detail.
The utility model provides the bridging arrangement of a kind of little car vehicle body upper back, and it comprises top cover after cross member and gusset, and, the upper back of described gusset and described top cover after cross member direct connection.With respect to prior art, the utility model has been cancelled the design of connecting panel.Wherein, the connecting portion of the connecting portion of the upper back of described gusset and described top cover after cross member can be mutual adaptive structure, certainly, the connecting portion of the connecting portion of the upper back of described gusset and described top cover after cross member can also be the structure of mutual close fit, is convenient to upper back and described top cover after cross member weld together with described gusset like this.
The bridging arrangement of little car vehicle body upper back that institute's the utility model is stated, wherein, the center at described direct coupled position is shorter than distance with described top cover after cross member with the distance of the upper back of described gusset.Further, the center at described direct coupled position can be arranged on the top, upper back of described gusset.Like this, by the redesign lap position, lap position is reduced near the back gusset, even is set directly at the top of back gusset, thereby improved the sheet material degree of utilization of gusset drawing and forming greatly.
The utility model has been optimized the design of bridging arrangement by adopting the cae analysis means, has cancelled the connecting panel of prior art, and gusset and top cover after cross member are directly overlapped, and has simplified structure herein.Owing to cancelled connecting panel, the body side wall manufacturing line has reduced special welding post and frock clamp, has simplified manufacturing line, only needs total welding to connect one procedure.And because bridging arrangement simple, reliable, eliminated the tail-gate risk of leaking, and also reduced welding cost simultaneously, improve body quality, be particularly suitable for requirements of mass production.
In test, find, adopt the welding quality and the stability of the body in white of bridging arrangement described in the utility model greatly to improve, also reduced simultaneously welding cost, the gusset manufacturing line of having simplified has exceeded the production capacity designing requirement, solved because of the part profile at all and worked poor, the tail-gate water inlet phenomenon that causes gluing also can't remedy.Because the optimization of structure also increases this regional rigidity of structure, thereby has improved the rigidity of whole body in white, makes new car body in white rigidity improve 2.35Hz.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
