Abstract
The utility model belongs to the technical field of automobile door frames, and provides a welding structure of an automobile door frame and connecting brackets. The welding structure comprises a door frame column B, an upper bar and a door frame column C, wherein a first connecting bracket is arranged on the door frame column B, a second connecting bracket is arranged on the door frame column C, the first connecting bracket consists of an upper welding part, a lower welding part and a welding connection part, the plane of the upper welding part is higher than that of the lower welding part, and an arched facing welding surface which is attached with the lower end of the door frame column B is arranged in a direction where the welding connection part and the upper welding part are connected. The welding structure has the advantages that the arched facing welding surface of the first connecting bracket and a side facing welding surface and an upper facing welding surface on the second connecting surface are welded together with the door frame column B and the door frame column C, therefore, the welding firmness of the connecting brackets and the door frame can be guaranteed, no cold solder joint can occur in the welding process, and the quality of the whole door frame can be guaranteed.
Description
Technical field
The utility model belongs to automobile door frame technical field, relates to a kind of automobile door frame and connection bracket welded structure.
Background technology
In automobile door frame assembly in order to facilitate the installation of doorframe, conventionally need to be welded with on doorframe connection bracket, the quality of therefore welding between connection bracket and doorframe directly has influence on the quality of whole doorframe assembly, between existing doorframe and connection bracket, there is following problem: the structure design between doorframe and connection bracket is unreasonable, in welding process, be easy to occur rosin joint, cause like this connection bracket to be connected with doorframe not firm, easily come off, and then have influence on the quality 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, firmly firm after welding, the automobile door frame of good integral strength and connection bracket welded structure.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of automobile door frame and connection bracket welded 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, the first described connection bracket comprises weld part, lower weld part and be welded to connect portion, the plane of described upper weld part is higher than the plane of lower weld part, in the described portion that is welded to connect and upper weld part closure, there is the welt face of weld that arches upward fitting with doorframe B post lower end.
The measure of taking for optimization such scheme specifically comprises:
In above-mentioned a kind of automobile door frame and connection bracket welded 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 by B post and the C post welded and installed of arch upward the side welt face of weld in welt face of weld and the second connection bracket, upper welt face of weld and the doorframe of the first connection bracket, guaranteed like this fastness after connection bracket and door frame welding, in welding process, there will not be rosin joint, thereby guaranteed the quality of whole doorframe.
Accompanying drawing explanation
Fig. 1 is this automobile door frame and connection bracket welded structure schematic diagram.
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; Upper weld part 6; Lower weld part 7; Be welded to connect portion 8; Welt face of weld 9 arches upward; Be welded to connect breach 10; Side welt face of weld 11; Upper welt face of weld 12.
As shown in Figure 1, this automobile door frame and connection bracket welded 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 first connection bracket 4 comprises weld part 6, lower weld part 7 and be welded to connect portion 8, the plane of upper weld part 6 is higher than the plane of lower weld part 7, be welded to connect in portion 8 and upper weld part 6 closures and there is the welt face of weld 9 that arches upward fitting with doorframe B post 1 lower end, here go up the plane of weld part 6 higher than the plane of lower weld part 7, by upper weld part 6, just can be soldered on the vehicle body of higher level like this, lower weld part 7 just can be soldered on the vehicle body of shorter plane, the welt face of weld 9 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, in the second connection bracket 5, offer and be welded to connect breach 10, on the left side that is welded to connect breach 10, be provided with the side welt face of weld 11 fitting with doorframe C post 3 lower ends, be welded to connect on the upper side position of breach 10 and be provided with the upper welt face of weld 12 fitting with doorframe C post 3 lower ends, the lower end of doorframe C post 3 is just positioned at and is welded to connect breach 10, then by 11 pairs of sides of side welt face of weld, position, by 12 pairs of top and bottom of upper welt face of weld, position again, thereby also firmly connect doorframe C post 3 and the second connection bracket 5, in welding process, there will not be rosin joint, thereby guaranteed the quality of whole doorframe.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from the defined scope of spirit of the present utility model.
