Abstract
The utility model discloses a front longitudinal beam structure for automobiles, which comprises a longitudinal beam body and a longitudinal outer plate. A reinforcing plate is arranged between the longitudinal beam body and the longitudinal outer plate, two lateral sides of the reinforcing plate are connected onto inner walls of the longitudinal beam body and the longitudinal outer plate respectively, the lateral side of the reinforcing plate close to the longitudinal beam body is provided with a groove, and a cavity is formed between the groove and the longitudinal beam body. The front longitudinal beam structure has the advantages that firstly, reinforcing structure is simple, manufacturing cost is low, and electrophoresis effect of the longitudinal beam and the reinforcing plate is improved, secondly, bearing capacity of mounting points of an automotive body when an automobile passes through pits and bumps at a high speed and turns at a high speed is improved, and thirdly, the Z-directional rigidity of the longitudinal beam at an engine mounting point is improved, and accordingly local bearing capacity of the longitudinal beam is improved.
Description
Technical field
The utility model relates to a kind of automobile front rail structure.
Background technology
Along with popularizing of fly-over highway and express highway, the car speed of a motor vehicle improves constantly, and protection driver and crew safety of life and property more and more comes into one's own.Dynamic assembly is the propulsion source of automobile, also is soruce of vibration simultaneously, and dynamic assembly is installed on vehicle body, the vehicle frame through mounting bracket, so very big load is born at vehicle body attachment point place.
The conventional engines vehicle body attachment point structural shape that suspends is a kind of U-shaped structure; Often the brace panel material rate of this structure than higher, the material thickness rate is thicker, for guarantee tempo turn with do not take place at a high speed that permanent deformation lost efficacy or fracture maybe two-layer brace panel through most evil bad condition automobile body structures such as hole, banks.The subject matter of traditional design is: longeron itself is exactly the very difficult control of U-shaped structure punch forming precision of an opening, adds that the brace panel of the inside also is the U-shaped structure of an opening, and the material property grade is high, the material thickness rate is thicker, and punch forming is difficult to control equally; The material thickness rate of brace panel is thicker simultaneously, causes tare to increase, and cost increases.This in addition structure is because the side of brace panel and the side of longeron body fit together, and the Z here increases little to rigidity.
The utility model content
The utility model technical matters to be solved is to the deficiency of prior art, a kind of automobile front rail structure that improves engine mounting vehicle body attachment point load-carrying capacity and strengthen electrophoretic effects to be provided.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of automobile front rail structure comprises longeron body and longeron outside plate, described longeron body and longeron outside plate weld together; Be provided with brace panel between described longeron body and the longeron outside plate; The upper and lower surface soldered of described brace panel is on the inwall of longeron body, and described brace panel is provided with groove near the side of longeron body, and forms cavity between the longeron body.
Described groove is vertical strip groove.
Described brace panel bottom is provided with the transverse concave groove that is connected with groove.
The utility model adopts said structure, and have the following advantages: 1, additional strengthening is simple, low cost of manufacture, the electrophoretic effects of raising longeron and brace panel; The load-carrying capacity of vehicle body attachment point when 2, improving automobile in tempo turn with at a high speed through hole, bank; 3, improve longeron at the Z at engine installation point place to rigidity, thereby improve the local load-carrying capacity of longeron.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation;
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the transverse sectional view of the utility model;
Fig. 3 is the longitudinal cross-section scheme drawing of the utility model;
In Fig. 1～Fig. 3,1, the longeron body; 2, longeron outside plate; 3, brace panel; 4, groove; 5, transverse concave groove.
The specific embodiment
Like Fig. 1～a kind of automobile front rail structure shown in Figure 3; Comprise longeron body 1 and longeron outside plate 2; Longeron body 1 and longeron outside plate 2 weld togethers; Be provided with brace panel 3 between longeron body 1 and the longeron outside plate 2, the upper and lower surface soldered of brace panel 3 is on the inwall of longeron body 1, and the contacts side surfaces of convexity on the brace panel 3 and longeron body forms the attachment point that suspends.Brace panel 3 is provided with groove 4 near the side of longeron body 1, and forms cavity between the longeron body 1.Groove 4 is vertical strip groove.Brace panel 3 bottoms are provided with the transverse concave groove 5 that is connected with groove 4.Form an osed top cavity between groove 4 and transverse concave groove 5 and the longeron body 1.
The utility model is through the improvement to body mount attachment point brace panel 3, increases the structural of brace panel, reduces manufacturing cost, also will satisfy the strength and stiffness requirement of various bad working environments under body attachment points.The projection welding of project-welding nut elder generation is to the brace panel 3 that suspends; And then be welded on the longeron body 1; 2 welding form cavity with the longeron outside plate more at last; So not only Z can be played to the effect of supporting in the limit on brace panel 3 both sides, and the closed cavity that groove 4 structures and longeron body form also plays Z to the support reinforcing effect; Whole longeron body, the brace panel that suspends, longeron outside plate form the weight that a closed cavity supports whole dynamic assembly; Can both alleviate weight at redundant some lightening holes of place increase of intensity simultaneously, can also improve longeron in-to-in application electrophoretic effects.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the various improvement of having adopted the technical scheme of the utility model to carry out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
