Abstract
The invention pertains to the field of manufacturing technologies of vehicles, in particular to a vehicle collision buffer energy absorption chassis structure. The chassis structure comprises an anti-collision beam and a longitudinal beam which is connected with the anti-collision beam, a strengthening component is arranged on the longitudinal beam to effectively solve the problems that when the vehicle is collided, the deformation of the longitudinal beam is too large, thereby causing the serious damage to the vehicle body and the personal injury to passengers in the prior art; the chassis structure has simple structure, reasonable design and very high practicality.
Description
Technical field
The invention belongs to technical field of vehicle manufacture, relate to a kind of body frame structure for automotive of vehicle, be specifically related to a kind of body frame structure for automotive with vehicle collision buffering energy-absorbing function.
Background technology
Vehicle frame is the installation basis of each parts on the vehicle, and it bears most of weight of car load, and when vehicle was subjected to impacting, vehicle frame can be subjected to impact load, therefore requires vehicle frame to have enough intensity, suitable rigidity.Vehicle frame generally comprise collision prevention girders and with collision prevention girders bonded assembly longeron, the insufficient strength of longeron in the vehicle frame of existing vehicle, when collision happens, because longeron insufficient strength, cause being out of shape excessive, cause car body badly damaged, must involve in the occupant area like this, produce huge momentum in the collision process and can be directly delivered among the crew module, cause the occupant to be subjected to great injury.
Summary of the invention
Low in order to solve the chassis side rail intensity that exists in the prior art, when collision happens, cause the longeron distortion excessive, make car body badly damaged, cause the problem of occupant's personal injury, the invention provides a kind of energy-absorbing frame structure for amortizing vehicle collision.
The present invention solves technical scheme that the prior art problem adopted for a kind of energy-absorbing frame structure for amortizing vehicle collision is provided, and described body frame structure for automotive comprises: collision prevention girders and with described collision prevention girders bonded assembly longeron, on described longeron, tension member is installed.
According to a preferred embodiment of the invention: described tension member is a brace panel.
According to a preferred embodiment of the invention: described brace panel comprises first brace panel and second brace panel; Wherein, described first brace panel is installed in the peristome in described longeron U type cross section; Described second brace panel is installed in the lower bottom part in described longeron U type cross section.
According to a preferred embodiment of the invention: described first brace panel is installed in the peristome in described longeron U type cross section, forms the cross section with described longeron and is the tetragonal structure of sealing.
According to a preferred embodiment of the invention: the mounting means of described tension member and described longeron is welding.
According to a preferred embodiment of the invention: through after the described welding, the spot pitch of formation is 37mm.。
Beneficial effect of the present invention be by on chassis side rail, add the tension member actv. solved exist in the prior art to cause longeron to be out of shape when the collision happens excessive, make car body badly damaged, cause the problem of occupant's personal injury, the present invention is simple in structure, reasonable in design, have very high practicality.
Description of drawings
Fig. 1. girder work scheme drawing in a kind of energy-absorbing frame structure for amortizing vehicle collision of the present invention;
Fig. 2. body frame structure for automotive scheme drawing in a kind of energy-absorbing frame structure for amortizing vehicle collision of the present invention.
The specific embodiment:
The invention will be further described below in conjunction with drawings and Examples:
See also longeron 100 structural representations in a kind of energy-absorbing frame structure for amortizing vehicle collision of Fig. 1 the present invention.As shown in Figure 1, on the described longeron 100 tension member is installed, what this tension member adopted in an embodiment of the present invention is the design of brace panel, and described brace panel comprises first brace panel 101 and second brace panel 102; Wherein, described first brace panel 101 is installed in the peristome in described longeron 100U type cross section, forms the cross section with described longeron 100 and is the tetragonal structure of sealing; Described second brace panel 102 is installed in the lower bottom part in described longeron 100U type cross section.Described first brace panel 101 and described second brace panel 102 are welding with the mounting means of described longeron 100.Through after the described welding, it is 37mm that solder joint 103 spacings of formation draw optimum value through cae analysis.
See also body frame structure for automotive scheme drawing in a kind of energy-absorbing frame structure for amortizing vehicle collision of Fig. 2 the present invention.Comprise collision prevention girders 201 in the described energy-absorbing frame structure for amortizing vehicle collision, the longeron 100 of tension member is installed, members such as camber beam 202 and cowl board 203, during Deng vehicle generation head-on crash, by sacrificing the member of operator's compartment front end, mainly comprise front anti-collision beam 201, camber beam 202, cowl board 203 etc., be out of shape the impact energy that absorbs the collision generation by the destruction of these members, but this distortion is unsuitable excessive again, because, if all deformation of members are excessive, will cause car body badly damaged, must involve in the occupant area like this, producing huge momentum in the collision process can be directly delivered among the crew module, cause the occupant to be subjected to great injury, so, the longeron 100 that brace panel is installed among the present invention can play actv. alleviates the excessive effect of deforming zone, and actv. alleviates occupant's personal safety that vehicle causes because of collision.
This technology can be brought into play protective action in vehicle front shock, utilize this technology, and when the afterbody of vehicle bumped, the longeron 100 that tension member is installed can play the actv. protective action equally.
Beneficial effect of the present invention be by on chassis side rail, add the tension member actv. solved exist in the prior art to cause longeron to be out of shape when the collision happens excessive, make car body badly damaged, cause the problem of occupant's personal injury, the present invention is simple in structure, reasonable in design, have very high practicality.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some deduction or replace, all should be considered as belonging to protection scope of the present invention.
