Abstract
The invention discloses a reinforcing structure for a front longitudinal beam of an automobile. The reinforcing structure is a box-shaped structure with a V-shaped opening; the reinforcing structure is mounted at the lapped part of a front longitudinal beam inner plate (1) and a vehicle body front baffle middle cross beam (2); the reinforcing structure comprises four surfaces, wherein a first side surface (3) and a second side surface (4), which are bilaterally symmetric to each other, are rectangular; a first bottom surface (5) and a second bottom surface (6), which are symmetric in a vertical direction, are both triangular; the first bottom surface (5) and the second bottom surface (6) are obtained by welding two sheet metal parts; the first side surface (3) is connected with the front longitudinal beam inner plate (1); and the second side surface (4) is connected with the vehicle body front baffle middle cross beam (2). The reinforcing structure for the front longitudinal beam of the automobile, disclosed by the invention, has the advantages as follows: as the V-shaped reinforcing box is additionally arranged at the lapped part of the front longitudinal beam inner plate and the vehicle body front baffle middle cross beam, a certain supporting effect is provided when the root part of the longitudinal beam cannot provide enough lateral support to enhance the rigidity of an engine suspending and mounting point, so that the vibrations and noises are reduced.
Description
Technical field
The present invention relates to a kind of vehicle body reinforcing structure, especially relate to a kind of reinforcement structure for automobile front longitudinal beam.
Background technology
Automobile front longitudinal beam is important body structure, not only plays the effect of fixed car power system, and bears important energy-absorbing function in auto against.
In the existing body structure, the root of front longitudinal girder inner plate does not generally have independent reinforcement structure to be connected with the crossbeam at vehicle body front apron middle part, structure shown in Figure of description 1, when the longeron root can not provide enough lateral support, just may cause engine mounting attachment point insufficient rigidity, produce larger vibration or noise, cause the NVH problem; Even the longeron root produces bending can cause bumping before the automobile time, increases the risk of occupant injury.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of reinforcement structure for automobile front longitudinal beam for problems of the prior art, its objective is that the root that improves automobile front longitudinal beam in the situation that does not affect arrangement space supports, reduce simultaneously noise, improve the energy-absorbing function of longeron.
Technical scheme of the present invention is that the reinforcement structure that this kind is used for automobile front longitudinal beam is the box like structure of v-shaped openings, and described reinforcement structure is installed in front longitudinal girder inner plate and vehicle body front apron center member overlapping part.
Described reinforcement structure comprises four faces, and wherein symmetrical the first side and the second side are rectangle, and the shape of laterally zygomorphic the first bottom surface and the second bottom surface all is triangle, and the first bottom surface and the second bottom surface all are to be formed by two the welding of sheet metal parts.
Described the first side is connected with front longitudinal girder inner plate, and described the second side is connected with vehicle body front apron center member.
Be equipped with the reinforced rib that increases its rigidity on described the first bottom surface and the second bottom surface.
Be equipped with the reinforced hole with flange on described the first bottom surface and the second bottom surface.
The reinforcement structure that this kind with said structure is used for automobile front longitudinal beam has the following advantages:
1. this kind is used for the reinforcement structure of automobile front longitudinal beam by increasing a V-type strengthen box at front longitudinal girder inner plate and vehicle body front apron center member overlapping part, certain supporting role when can not providing enough lateral support, the longeron root is provided, strengthen the rigidity of engine mounting attachment point, thus absorb vibration and noise.
This kind be used for automobile front longitudinal beam the reinforcement Structure Decreasing when bumping before the automobile front side member root produce the probability of bending, improved the safety guard-safeguard performance to driver and crew.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the mounting structure scheme drawing of front longitudinal girder inner plate and vehicle body front apron center member in the prior art.
Fig. 2 is structural representation of the present invention.
In Fig. 1-2,1: front longitudinal girder inner plate; 2: vehicle body front apron center member; 3: the first sides; 4: the second sides; 5: the first bottom surfaces; 6: the second bottom surfaces; 7: reinforced rib; 8: reinforced hole.
The specific embodiment
By the combination of structure shown in Fig. 1-2 as can be known, the reinforcement structure that this kind is used for automobile front longitudinal beam is the box like structure of v-shaped openings, and the reinforcement structure is installed in front longitudinal girder inner plate 1 and vehicle body front apron center member 2 overlapping parts.Strengthen structure and comprise four faces, wherein symmetrical the first side 3 and the second side 4 are rectangle, and the shape of laterally zygomorphic the first bottom surface 5 and the second bottom surface 6 all is triangle, and the first bottom surface 5 and the second bottom surface 6 all are to be formed by two the welding of sheet metal parts; The first side 3 is connected with front longitudinal girder inner plate 1, and the second side 4 is connected with vehicle body front apron center member 2.During assembling, welding can also can be realized by plug welding by mode and front longitudinal girder inner plate 1 welding of freezing in the first side 3, if assembled condition is restricted, can also connects by riveted joint or bolt and realize.The second side 4 also can be welded with above-mentioned similar welding manner and vehicle body front apron center member 2.
Be equipped with the reinforced hole 8 that also is provided with on reinforced rib 7, the first bottom surfaces 5 that increase its rigidity and the second bottom surface 6 with flange on the first bottom surface 5 and the second bottom surface 6, when reducing the weight of strengthening structure, improved the intensity of strengthening structure.
This kind is used for the reinforcement structure of automobile front longitudinal beam by increasing a V-type strengthen box at front longitudinal girder inner plate and vehicle body front apron center member overlapping part, certain supporting role when can not providing enough lateral support, the longeron root is provided, strengthen the rigidity of engine mounting attachment point, thus absorb vibration and noise; Simultaneously, reduce the probability of front side member root generation bending when bumping before the automobile, improved the safety guard-safeguard performance to driver and crew.
