Abstract
The utility model provides a car tail -gate middle part reinforcing plate structure, it is a symmetry piece, including the reinforcing plate body, the reinforcing plate body is the triumph generally, and six welding regions are connected with car door inner panel as follows mainly, the utility model discloses a carry out the optimal design to automobile tail -gate structure, strengthen automobile tail -gate air spring installation region, through CAE simulation and analysis and experiment test, verify that it on guaranteeing the basis that the manufacturability was easily realized, has improved the not enough problem of automobile tail -gate middle part bending stiffness to can improve the regional tired longevity of switching door stroke of luck spring mounting repeatedly, it has advantages such as simple structure, application scope guangZhou, and the mountable is in the tail -gate of numerous cars constructs.
Description
Technical field
This utility model belongs to Manufacturing Technology for Automotive Parts field, reinforcing plate structure in the middle part of specifically a kind of automobile tail gate.
Background technology
The middle bent rigidity of automobile tail gate is an important inspection target, if automobile tail gate middle bent rigidity is unsatisfactory for designing requirement, has bigger sinking, car door can be caused time serious to destroy after tail-gate is opened；Additionally during automobile tail gate opens and closes, air spring near zone has bigger stress concentration phenomenon, if this regional structure is more weak, along with increasing of access times, can produce damage accumulation, until there is fatigue rupture.
Summary of the invention
The purpose of this utility model is to provide reinforcing plate structure in the middle part of a kind of automobile tail gate, which increases the fatigue life of the gentle spring mounting regions of tail-gate middle bent rigidity.
The technical solution of the utility model is: reinforcing plate structure in the middle part of a kind of automobile tail gate, including reinforcing plate body and air spring, it is characterized in that: described reinforcing plate body is generally in triangular form shape, at vertical direction, there is "Ji" type shape, having six welding regions, described reinforcement body is welded together with inner plate of car door by six welding regions；Having installing hole in the middle part of reinforcing plate, air spring is installed in tail-gate structure by installing hole by bolt.
The utility model has the advantages that: by automobile tail gate structure is optimized design, automobile tail gate air spring installation region is strengthened, by CAE simulation analysis and experiment test, confirm that it is on the basis of ensureing that manufacturability is easily achieved, the problem improving automobile tail gate middle bent insufficient rigidity, and the fatigue life of opening and closing car door seasonal epidemic pathogens spring mounting regions repeatedly can be improved；It has simple in construction, the advantage such as applied widely, is mountable in the tail-gate structure of numerous automobile.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Fig. 1 is this utility model left side structure isometric views；
Fig. 2 is this utility model right side structure isometric views；
Reference is as follows: 1 reinforcing plate body, 2 welding region-A, 3 welding region-B, 4 welding region-C, 5 welding region-D, 6 welding region-E, 7 welding region-F, 8 installing holes.
Below in conjunction with accompanying drawing and by example, utility model is described in further detail; but the following example example therein that is only this utility model; not representing the rights protection scope that this utility model is limited, rights protection scope of the present utility model is as the criterion with claim.
Detailed description of the invention
According to Fig. 1, this utility model is described in detail.Reinforcing plate structure in the middle part of a kind of automobile tail gate of the present utility model, include reinforcement body 1, there are six welding regions to be respectively as follows: 2 welding region-A, 3 welding region-B, 4 welding region-C, 5 welding region-D, 6 welding region-E, 7 welding region-F on reinforcement body 1, there is in the middle part of reinforcing plate body air spring installing hole 8.
In order to improve rigidity and the intensity of reinforcing plate body, reinforcing plate body 1 is generally in triangular form, at vertical direction, there is "Ji" type feature, the high stability of triangular form structure and the high bending of "Ji" type structure are combined, can significantly improve the fatigue life of the gentle spring mounting regions of tail-gate middle bent rigidity.
During use, by left and right two symmetrical reinforcing plate structures of the present utility model, by the welding of six positions, body 1 is connected with inner plate of car door, by air spring installing hole 8, air spring is installed on car door.In sum, it is achieved that the purpose of this utility model.
