Abstract
The invention relates to the technical field of an automotive body in white, and discloses a tail-gate hinge reinforcing plate. The tail-gate hinge reinforcing plate comprises a flat plate; and the flat plate is provided with welding edges and a mounting passage for mounting a tail-gate hinge. The tail-gate hinge reinforcing plate has the following advantages: for a top cover back crossbeam welded piece provided with a tail gate and a hinge assembly of the tail gate, by welding the reinforcing plate with an internal plate and an external plate of a top cover back beam simultaneously, the internal plate and the external plate of the top cover back beam are stressed simultaneously so as to enlarge stressing area, improve strength and rigidity of the top cover back crossbeam welded piece greatly, and improve quality of an integral vehicle.
Description
Technical field
The present invention relates to body in white and make field, particularly a kind of tail-door hinge stiffening plate.
Background technology
For the vehicle that tail-gate is arranged, as microbus, MPV and SUN etc., general tail-gate is heavier, cause that easily tail-gate sinks, produce the problem of gap section difference and so on, this has just had higher requirement to the intensity of its junction, now domesticly generally solves this problem by increasing the stiffener structure, but in general present stiffener exists the problem of strength deficiency or complex structure complex process.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of tail-door hinge stiffening plate, mode by the improvement hinge stiffening plate, hinge stiffening plate is welded with the inside and outside plate of top cover rear cross beam simultaneously, sink to causing car load presentation quality difference and driving process to produce the phenomenon of abnormal sound thereby solved because of there be not enough the causing of bonding strength in tail-gate.
The present invention solves the technical scheme that the prior art problem adopted: design and make a kind of tail-door hinge stiffening plate, comprise surface plate, described surface plate is provided with welding edge, and described surface plate is provided with the installation passage that is used to install tail-door hinge; Described welding edge has three, be positioned at surface plate around, connect by transition face.
The present invention further improves: described welding edge is the toe of strip type, and described welding edge is positioned at the end of described transition face.
The present invention further improves: the described installation passage that is used to install tail-door hinge is circular hole or slotted hole.
The present invention further improves: described surface plate, transition face and three welding edges are combined to form support.
The present invention further improves: described welding edge is provided with reinforcing rib, and described reinforcing rib is positioned at described welding edge and described transition face intersection.
The present invention further improves: described surface plate is the rectangle plane plate; Described welding edge comprises three toes, and it lays respectively at wherein three limits of described surface plate, is connected with transition face; Described arbitrary toe is welded with the top cover rear cross beam inner panel that is connected in this toe.
The present invention further improves: the described installation passage that is used to install tail-door hinge is one or two.
The invention has the beneficial effects as follows: for the top cover rear cross beam soldering member that tail-gate and hinge assembly thereof have been installed, by adopting stiffener to weld with top cover back rest inner and outer plates simultaneously, make top cover back rest inner and outer plates simultaneously stressed, thereby strengthened lifting surface area, improved the strength and stiffness of top cover rear cross beam soldering member significantly.
Description of drawings
Fig. 1 is a tail-door hinge stiffening plate structural representation of the present invention;
Fig. 2 is tail-door hinge stiffening plate of the present invention and top cover back rest connection diagram.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of tail-door hinge stiffening plate comprises surface plate 1, and described surface plate 1 is provided with welding edge 4, and 1 is provided with the installation passage 3 that is used to install tail-door hinge on the described surface plate; Described welding edge has three, be positioned at surface plate around, connect by transition face.
Institute's welding edge 4 is the toe of strip type, described welding edge 4 is the toe of strip type, and described welding edge 4 is positioned at the end of described surface plate transition face 2, and described welding edge 4 is positioned at the end of described transition face 2, this transition face 2 can be provided with chamfering, and this welding edge 4 is connected with this chamfering.
The described installation passage that is used to install tail-door hinge is circular hole or slotted hole, is circular hole as among Fig. 1 passage being installed.
Described surface plate 1, transition face 2 and three welding edges 4 are combined to form support.
Described welding edge 4 is provided with reinforcing rib 5, and described reinforcing rib 5 is positioned at described welding edge 4 and described transition face 2 intersections, and it is to play booster action that reinforcing rib 5 is placed on the flanging.
Described surface plate 1 is the rectangle plane plate; Described welding edge 4 comprises three toes, and it lays respectively at wherein three limits of described surface plate 1, is connected with transition face; Described arbitrary toe is welded with the top cover rear cross beam inner panel that is connected in this toe, and the purpose of doing like this is when satisfying booster action, and test weld connects the technology simplification as far as possible, is convenient to operation.
The described installation passage 3 that is used to install tail-door hinge is one or two.
The described installation passage that is used to install tail-door hinge is one or two.By circular hole 3, can very easily hinge be connected, select the type of installing hole according to actual conditions, can be single hole, also can be diplopore, and the hole also can be circular hole, slotted hole, even can also be square hole, adjust according to actual conditions, make things convenient for piercing into of hinge.
In the actual conditions, as Fig. 2, the support rack type hinge stiffening plate is welded with top cover rear cross beam inner panel 11 respectively by three welding edges 121314, stiffener and top cover rear cross beam are welded with top cover rear cross beam outside plate again, outside plate welds with inner panel and hinge stiffening plate simultaneously, form top cover rear cross beam soldering member, connecing the workshop in total welding pieces together top cover rear cross beam soldering member on body in white, in subsequent handling, again with tail-gate and hinge assembly by the self-locking nut structure body in white of packing into, improved the lifting surface area of hinge stiffening plate by such mode, the strength and stiffness of top cover rear cross beam soldering member have been improved, improved the bonding strength of tail-gate assembly and vehicle body, can prevent effectively that tail-gate from sinking and the phenomenon of distortion.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
