Description
Technical field
The utility model belongs to doorframe technical field, and the bending that relates to a kind of automobile door frame improves structure.
Background technology
The door frame structure of automobile is mainly to be gone out many folding parts and had complicated shape of cross section by flow forming, and shape of cross section when with the assembling of other opponent's part to seal ability and ornamental playing a decisive role, the shortcoming that the door frame of existing automobile mainly exists is: rolling technology step is complicated, and after installing with opponent's part, leak tightness is poor, the right-hand member of doorframe upper strip can not have the variation of wide-angle, the shape of whole like this doorframe is just restricted, if doorframe upper strip carries out roll bending separately, easily there is too greatly again fracture in angle, and then have influence on the normal use of whole doorframe.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of simple in structure, and bending angle is large, and the bending of the automobile door frame of good integral strength improves structure.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of bending of automobile door frame improves structure, comprise doorframe B post, upper and doorframe C post, on described doorframe B post, the first connection bracket is installed, on described doorframe C post, the second connection bracket is installed, it is characterized in that, described upper comprise main part and the camber line kink that one connects, upper end and the main part left end of doorframe B post are welded to connect, the relative main part of camber line kink is crooked to bottom right, and described doorframe C post and camber line kink are welded to connect and inside lateral inclination.
The measure of taking for optimization such scheme specifically comprises:
Bending at above-mentioned a kind of automobile door frame improves in structure, and the place of being welded to connect of described camber line kink and doorframe C post offers inclined weld interface.
Bending at above-mentioned a kind of automobile door frame improves in structure, the first described connection bracket comprises weld part, lower weld part and is welded to connect portion, the plane of described upper weld part, higher than the plane of lower weld part, has the welt face of weld that arches upward fitting with doorframe B post lower end in the described portion that is welded to connect and upper weld part closure.
Bending at above-mentioned a kind of automobile door frame improves in structure, in the second described connection bracket, offer and be welded to connect breach, be provided with the side welt face of weld fitting with doorframe C post lower end being welded to connect on the left side of breach, on the described upper side position that is welded to connect breach, be provided with the upper welt face of weld fitting with doorframe C post lower end.
Compared with prior art, the utility model has the advantage of: simple in structure, bending angle is large, good integral strength, due to upper, there is camber line kink and the welding of doorframe C post, so not only guaranteed that doorframe has certain bending angle, also guaranteed to be welded to connect the intensity at place simultaneously, by the side welt face of weld arching upward in welt face of weld and the second connection bracket of the first connection bracket, the B post of upper welt face of weld and doorframe and C post welded and installed, guaranteed like this fastness after connection bracket and door frame welding, in welding process, there will not be rosin joint, guaranteed the intensity of doorframe integral body.
Accompanying drawing explanation
Fig. 1 is that the bending of this automobile door frame improves structural representation.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
In figure, doorframe B post 1; Upper 2; Doorframe C post 3; The first connection bracket 4; The second connection bracket 5; Main part 6; Camber line kink 7; Inclined weld interface 8; Upper weld part 9; Lower weld part 10; Be welded to connect portion 11; Welt face of weld 12 arches upward; Be welded to connect breach 13; Side welt face of weld 14; Upper welt face of weld 15.
As shown in Figure 1, the bending of this automobile door frame improves structure, comprise doorframe B post 1, upper 2 and doorframe C post 3, the first connection bracket 4 is installed on doorframe B post 1, the second connection bracket 5 is installed on doorframe C post 3, the utility model and the difference of existing maximum be upper 2 comprise main part 6 and the camber line kink 7 that one is connected, the upper end of doorframe B post 1 and main part 6 left ends are welded to connect, the relative main part 6 of camber line kink 7 is crooked to bottom right, doorframe C post 3 is welded to connect with camber line kink 7 and inside lateral inclination, so just make whole doorframe bending angle large, good integral strength, having overcome existing doorframe can not have the defect of the variation of wide-angle, here in order to facilitate doorframe C post 3 and 7 welding of camber line kink, camber line kink 7 offers inclined weld interface 8 with the place of being welded to connect of doorframe C post 3.
The first connection bracket 4 comprises weld part 9, lower weld part 10 and be welded to connect portion 11, the plane of upper weld part 9 is higher than the plane of lower weld part 10, be welded to connect in portion 11 and upper weld part 9 closures and there is the welt face of weld 12 that arches upward fitting with doorframe B post 1 lower end, here go up the plane of weld part 9 higher than the plane of lower weld part 10, by upper weld part 9, just can be soldered on the vehicle body of higher level like this, lower weld part 10 just can be soldered on the vehicle body of shorter plane, the welt face of weld 12 that arches upward just fits with doorframe B post 1 lower end, so just can firmly connect doorframe B post 1 and the first connection bracket 4.
