Abstract
The utility model discloses a top cover rear cross beam welding component, belonging to the technical field of automotive body parts; the top cover rear cross beam welding component comprises a top cover rear cross beam inner plate, a rear cross beam outer plate and a tail gate hinge reinforcing plate; the front end of the tail gate hinge reinforcing plate is welded with the top cover rear cross beam inner plate and the rear cross beam outer plate simultaneously, and the rear end of the tail gate hinge reinforcing plate is welded with the top cover rear cross beam outer plate; the structure which is optically designed is adopted, by changing the overlap jointing relation and increasing the ribs, the rigidity and local intensity of the top cover rear cross beam welding component can be effectively increased, so as to effectively solve the problem that the distortion of the top cover rear cross beam welding component is obvious and effectively control the problem that the hinge mounting surface position of the top cover rear cross beam outer plate cracks simultaneously; in addition, the component is beneficial to finishing the mold state without affecting the welding and assembling processed, and the problem of surface quality can not be generated, and the cost is not increased hardly.
Description
Technical field
The utility model belongs to auto body parts technical field, especially relates to a kind of top cover after cross member seam assembly.
Background technology
The tail-door hinge stiffening plate structure that is used for top cover after cross member soldering member of domestic little car mainly is divided into 3 kinds at present: 1) L type structure, only weld with the after cross member outside plate, the local reinforcement played in the tail-door hinge installation place, but size is less, and only weld with top cover after cross member outside plate, under tail-gate gravity and the effect of tail-gate gas spring power, top cover after cross member soldering member sag of chain is bigger, even causes top cover after cross member outside plate hinge face place to go out cracking; 2) improved structure, weld with top cover after cross member inner panel respectively by three welding edges, this kind project organization complexity, stamping procedure and welding sequence are more, the problem that can cause the harness, lift gate difficulty to wear also, do not having under the situation of roof liner simultaneously, the solder joint of top cover after cross member inner panel and hinge stiffening plate exposes, and surface quality problems occurs; 3) between the gusset inner and outer plates of back, increase a bulk of brace panel, stretch out with the top cover after cross member and be connected, by large-area brace panel, overlap the tail-gate junction with the top cover after cross member, when increasing car load mode, serve as tail-door hinge stiffening plate, the tail-door hinge stiffening plate complex structure of this kind structure, part is bigger, increase tare, the cost height.
The utility model content
The purpose of this utility model is to provide a kind of new tail-door hinge stiffening plate structure, can not produce harmful effect to other technologies or zone under the situation that satisfies rigidity and intensity, solves the defective that prior art exists.
For achieving the above object, the utility model adopts following technical scheme:
A kind of top cover after cross member seam assembly comprises top cover after cross member inner panel, after cross member outside plate and tail-door hinge stiffening plate; The front end of described tail-door hinge stiffening plate and described top cover after cross member inner panel, after cross member outside plate weld simultaneously, the rear end of described tail-door hinge stiffening plate and the welding of top cover after cross member outside plate.
Preferred scheme is: described tail-door hinge stiffening plate front end is provided with 2-5 bar waling rib, and the part, rear end is provided with 2-5 triangle muscle.
More preferred scheme is: described waling rib diameter is 10-16mm, and the spacing of muscle and muscle is 12-18mm, and rib length is 60-70mm.
More preferred scheme is: described waling rib is 3, and diameter is 13mm, and the spacing of muscle and muscle is that 16mm equidistantly arranges, and rib length is 65mm.
More preferred scheme is: described tail-door hinge stiffening plate both sides of the edge are provided with the flange of strengthening usefulness.
The utility model compared with prior art exists following advantage and beneficial effect:
The structure of the optimal design that the utility model is related, by change bonding relation and increase rib mode, the rigidity and the local strength of top cover after cross member soldering member have been increased effectively, thereby effectively solve the excessive problem of amount of top cover after cross member soldering member distortion, can effectively suppress simultaneously the problem that top cover after cross member outside plate hinge face place goes out cracking, also more help simultaneously car load mode, and do not influence technologies such as welding, general assembly, can not produce surface quality problems, increase cost hardly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model tail-door hinge stiffening plate assembling local structure enlarged diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details:
As shown in Figure 1 and Figure 2, a kind of top cover after cross member seam assembly comprises top cover after cross member inner panel 2, after cross member outside plate 1 and tail-door hinge stiffening plate 3; Front end 31 and outer 1 plate of top cover after cross member, inner panel 2 welding with tail-door hinge stiffening plate, the rear end 32 of tail-door hinge stiffening plate and 1 welding of top cover after cross member outside plate, tail-door hinge stiffening plate front end 31 is arranged 3 walings 33 simultaneously, circle muscle diameter 13mm is, the spacing of muscle and muscle is that 16mm equidistantly arranges, and rib length is 65mm; Local 3 the triangle muscle 34 of arranging are arranged in tail-door hinge stiffening plate rear end 32; The tail-door hinge stiffening plate both sides of the edge are provided with the flange 35 of strengthening usefulness.Present embodiment top cover after cross member soldering member Deformation control in the reasonable scope, the stress value at top cover after cross member outside plate hinge face place is controlled at 115.1Mpa, and the vertical deformation amount of top cover after cross member soldering member is controlled at the intensity that 0.907mm. has effectively increased top cover after cross member rigidity and hinge face.
Present embodiment is changed its overlapping mode by the tail-door hinge stiffening plate structure is optimized, and it is welded simultaneously with top cover after cross member inner and outer plates simultaneously, and solder joint does not expose.Simultaneously, optimize its size, increase oval rib thereon, increase the flange of strengthening usefulness.It is not only simple in structure, has enough rigidity.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
