Abstract
The invention provides a vehicle door reinforcing piece. The vehicle door reinforcing piece comprises a vehicle door lower beam, a vehicle door stopper reinforcing piece, a vehicle door inner skin and a vehicle door lower beam front support. The vehicle door lower beam front support is in an L shape. Two installation faces serve as the two edges of the L shape. One installation face is welded to the corresponding position, provided with a vehicle door hinge, of the vehicle door stopper reinforcing piece, wherein screw holes used for being connected with the vehicle door hinge are formed in the installation face and overlap screw holes used for installing the vehicle door hinge on the vehicle door stopper reinforcing piece. The other installation face of the vehicle door lower beam front support is welded to the front portion of the vehicle door lower beam. The vehicle door lower beam front support is additionally arranged between an existing stopper reinforcing piece and the vehicle door lower beam, and therefore the effect of reinforcing the vehicle door hinge installation portion can be achieved, and the anti-collision performance of a vehicle door can also be improved.
Description
Technical field
The present invention relates to a kind of weldment of auto body system closure member field.
Background technology
At present, there is certain defect in car door: body hinge is the critical component of connection body and car door in the design strengthening structure, and be also the main stressed member of car door, car door opens and closes round hinge axis simultaneously.One end of body hinge is mounted on door inner covering, the car door limiter reinforcement installation site on door inner covering is just being corresponded in installation place, therefore be connected with car door limiter reinforcement by bolt, because the material of door inner covering is usually thinner, very large power can not be born when car door opening, therefore Long-Time Service, door inner covering can produce distortion because of insufficient strength; In addition, the entirety of car door is thin-slab structure, undercapacity, especially when colliding, can threaten safely to the life of passenger, and when running at high speed, undercapacity also may cause car door abnormal sound.Therefore, in existing vehicle, usually on door inner covering, car door cross sill is welded to increase the intensity of car door, but without direct bonding relation between car door cross sill and car door limiter reinforcement, the reinforcement so just forming body hinge attachment point mainly relies on single limiting device reinforcement, and the impact strength improving car door relies on is Lower Crossbeam Structure together with automobile door welding, these two kinds of separate structures of structure, can not improve the intensity of car door on the whole.
In order to improve the collision safety intensity of body hinge installation position intensity and enhancing car door, the present invention proposes a kind of arrangements for automotive doors reinforcement, it sets up car door cross sill front frame between original limiting device reinforcement and car door cross sill, both booster action was played to body hinge installation position, the crashworthiness of car door can be improved again.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: car door reinforcement comprises car door cross sill, car door limiter reinforcement and door inner covering, car door cross sill horizontal welding is in door inner covering bottom, and car door limiter reinforcement is welded on the position of door inner covering side mounting limit device; The present invention also comprises a car door cross sill front frame, and car door cross sill front frame is L-shaped, and the both sides of L shape are respectively two attachment faces, and an attachment face is welded on the correspondence position of installation car door hinge on car door limiter reinforcement; This attachment face is provided with the screw for connecting body hinge, and overlapping with the screw of installation car door hinge on car door limiter reinforcement, another attachment face of car door cross sill front frame welds with the front portion of car door cross sill.
Further, described car door cross sill front frame is provided with the convex tendon be connected in the centre of two attachment faces.
Further, described support perimeter is provided with flange.
Compared with prior art, in this structure, owing to weld with car door limiter reinforcement and car door cross sill respectively by car door cross sill front frame, by original two independently structure be linked to be integrally, both improve the intensity of body hinge installation position, turn improve the intensity of door inner covering simultaneously; In addition, for car door cross sill front frame, be designed to L shape structure, and arrange convex tendon at middle part, periphery design turnup structure, further enhancing the intensity of itself, the intensity being more conducive to whole reinforcement structure improves.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is structural representations of car door cross sill front frame.
In figure: 1-car door cross sill, 2-car door cross sill front frame, the reinforcement of 3-car door limiter, 4-door inner covering, 5-body hinge, 21-first attachment face, 22-second attachment face, 23-flange, 24-convex tendon.
Detailed description of the invention
Below in conjunction with accompanying drawing 1,2, the invention will be further elaborated.
This door reinforced structure comprises car door cross sill 1, car door cross sill front frame 2, car door limiter reinforcement 3, door inner covering 4.Wherein car door cross sill front frame 2 is L-shaped, the both sides of L shape are respectively the first attachment face 21 and the second attachment face 22, be respectively arranged with the convex tendon 24 be connected in the centre of two attachment faces, this support perimeter is provided with flange 23 simultaneously, to improve the intensity of this support.Second attachment face 22 of car door cross sill front frame 2 is provided with the screw for connecting body hinge 5, and this attachment face is welded on car door limiter reinforcement 3, the first attachment face 21 welds with the front portion of car door cross sill 1.Car door limiter reinforcement 3 and car door cross sill 1 are all welded on door inner covering 4, car door limiter reinforcement 3 is also provided with the screw for connecting body hinge, this screw is overlapping with the screw of car door cross sill front frame 2, one end of body hinge 5 is connected with described car door limiter reinforcement 3 and car door cross sill front frame 2 by bolt, and the other end is connected with car body bolt.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
