Abstract
The invention relates to an automobile door reinforced structure comprising an automobile door lower beam, an automobile door stopper reinforced member, an automobile door inner skin and an L-shaped front bracket of the automobile door lower beam, wherein two edges of the L shape are respectively two fitting surfaces, one fitting surface is welded on the corresponding position on the automobile door stopper reinforced member, which is provided with an automobile door hinge; the fitting surface is also provided with a screw hole for connecting with the automobile door hinge, and the screw is overlapped with a screw which is used for installing the automobile door hinge on the automobile door stopper reinforced member; the other fitting surface of the front bracket of the automobile door lower beam is welded with the front part of the automobile door lower beam. The automobile door reinforced structure adds the front bracket of the automobile door lower beam between the original stopper reinforced member and the automobile door lower beam, which performs the reinforced function to the automobile door hinge installation position and can improve the anti-collision performance of the automobile door.
Description
Technical field
The invention belongs to the weldment in auto body system closure member field
Background technology
Car door is as the important component part in the body structure, and its shaping style, intensity, rigidity, reliability and manufacturability etc. must satisfy the requirement of vehicle body overall performance.There is certain defective in existing car door in the design of additional strengthening:
On the one hand, body hinge is the critical component that connects car body and car door, also is the main stressed member of car door simultaneously, and car door opens and closes round hinge axis.One end of body hinge is mounted on the car door inside panel; In the installation place just corresponding to the car door limiter reinforcement installation site on the car door inside panel; Therefore be connected with the car door limiter reinforcement through bolt,, when car door opening, can not bear very big power because the material of car door inside panel is thinner usually; Therefore long-term use, the car door inside panel can produce distortion because of insufficient strength;
On the other hand, the integral body of car door is thin-slab structure, and undercapacity especially when bumping, can the life safety of passenger be threatened, and when running at high speed, undercapacity also may cause the car door abnormal sound.Therefore; In existing vehicle, welding tractor student crossbeam increases the intensity of car door on the car door inside panel usually, but no direct bonding relation between car door cross sill and the car door limiter reinforcement; The reinforcement that so just forms the body hinge attachment point mainly relies on mono-limiting device reinforcement; And the impact strength that improves car door relies on is the cross sill structure with the car door weld together, and these two kinds of separate structures of structure can not improve the intensity of car door on the whole.
Summary of the invention
In order to improve body hinge installation position intensity and the collision safety intensity that strengthens car door; The present invention proposes a kind of automobile door reinforced structure; It sets up car door cross sill front frame between original limiting device reinforcement and car door cross sill; Both booster action was played in the body hinge installation position, can improve the crashworthiness of car door again.
Technical scheme of the present invention:
A kind of automobile door reinforced structure, it comprises car door cross sill, car door limiter reinforcement, car door cross sill front frame and car door inside panel.Said car door cross sill horizontal welding is in car door inside panel bottom; Said car door limiter reinforcement is welded on the car door inside panel; Said car door limiter reinforcement is welded on the position that limiting device is installed on the car door inside panel; Via hole and mounting hole that limiting device is installed are arranged on the limiting device reinforcement, and the position that body hinge is installed in correspondence is provided with screw.
Said car door cross sill front frame is L-shaped; L shaped both sides are respectively two attachment faces; An attachment face is welded on the correspondence position that body hinge is installed on the car door limiter reinforcement; On this attachment face, also be provided with the screw that is used to connect body hinge, overlapping with the screw that body hinge is installed on the car door limiter reinforcement, another attachment face of car door cross sill front frame and the welding of the front portion of car door cross sill.Body hinge one end is connected the other end and car body bolt together through bolt with the car door limiter reinforcement with car door cross sill front frame.
Further, said car door cross sill front frame is provided with the convex tendon that fuses in the centre of two attachment faces, and the support periphery is provided with flange.
In this structure; Owing to weld with car door limiter reinforcement and car door cross sill respectively through car door cross sill front frame, original two independent structures be linked to be one, like this; Both improved the intensity of body hinge installation position; Improve simultaneously the intensity of car door inside panel again, just improved the bulk strength and the crashproof ability of car door thus, ensured the life safety of passenger.
In addition, for car door cross sill front frame, it is designed to L shaped structure, and at the middle part convex tendon is set, periphery design turnup structure has further strengthened intensity own, and the intensity that more helps whole additional strengthening improves.

The specific embodiment
Referring to Fig. 1 and Fig. 2, this door reinforced structure comprises car door cross sill 1, car door cross sill front frame 2, car door limiter reinforcement 3, car door inside panel 4.
As shown in Figure 2; Wherein car door cross sill front frame 2 is L-shaped, and L shaped both sides are respectively first attachment face 21 and second attachment face 22, is respectively arranged with the convex tendon 24 that fuses in the centre of two attachment faces; This support periphery is provided with flange 23 simultaneously, to improve the intensity of this support.
Referring to Fig. 1, second attachment face 22 of car door cross sill front frame 2 is provided with the screw that is used to connect body hinge 5, and this attachment face is welded on the car door limiter reinforcement 3 the front portion welding of first attachment face 21 and car door cross sill 1.Car door limiter reinforcement 3 all is welded on the car door inside panel 4 with car door cross sill 1; Also be provided with the screw that is used to connect body hinge on the car door limiter reinforcement 3; The screw of this screw and car door cross sill front frame 2 is overlapping; One end of body hinge 5 is connected the other end and car body bolt together through bolt with said car door limiter reinforcement 3 with car door cross sill front frame 2.
