Abstract
The invention discloses an anti-collision beam structure of a bus. The anti-collision beam structure of the bus comprises an anti-collision beam, wherein the anti-collision beam is connected with a frame cross beam of the bus through at least one energy-absorbing longitudinal beam. Through the additional arrangement of the anti-collision beam structure, in comparison with the traditional bus, when the bus suffers from head-on collision, the anti-collision beam structure can furthest absorb energy; and therefore, the strength of the bus framework, in particular the bottom framework is improved remarkably, so that the safety of people in the bus is guaranteed.
Description
Technical field
The invention belongs to the automotive body structure technical field, relate in particular to a kind of passenger vehicle collision prevention girders structure.
Background technology
At present, national legislation claims to collision prevention girders in passenger vehicle collision field, and passenger vehicle does not arrange the collision prevention girders structure usually in the native land.But owing to lacking collision prevention girders, when passenger vehicle runs into head-on crash, be difficult to guarantee the safety of occupant, especially chaufeur and front-seat passenger.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of passenger vehicle collision prevention girders structure, is installed on the passenger vehicle, can effectively increase central collision intensity, improves occupant's safety factor.
Purpose of the present invention will be achieved by the following technical programs:
A kind of passenger vehicle collision prevention girders structure comprises a collision prevention girders, and described collision prevention girders is connected with the cross member of frame of passenger vehicle by the energy-absorbing longeron of at least one.
Preferably, above-mentioned passenger vehicle collision prevention girders structure, wherein: described collision prevention girders is formed in one, and described collision prevention girders is the strip of neutral straight, two ends bending.
Preferably, above-mentioned passenger vehicle collision prevention girders structure, wherein: the transversal surface of described collision prevention girders is " day " character form structure with two hollow cavities.
Preferably, above-mentioned passenger vehicle collision prevention girders structure, wherein: the edge of described collision prevention girders is provided with chamfering.
Preferably, above-mentioned passenger vehicle collision prevention girders structure, wherein: described energy-absorbing longeron is provided with the energy-absorbing muscle of at least one, can significantly absorb energy when vehicle runs into strong collision, reduces impact force to occupant's injury.
Preferably, above-mentioned passenger vehicle collision prevention girders structure, wherein: described energy-absorbing muscle is arranged on the horizontal and/or longitudinal direction of described energy-absorbing longeron.
Preferably, above-mentioned passenger vehicle collision prevention girders structure, wherein: described collision prevention girders and described energy-absorbing longeron are bolted, and described energy-absorbing longeron and described cross member of frame are bolted.
Preferably, above-mentioned passenger vehicle collision prevention girders structure, wherein: the material of described collision prevention girders and energy-absorbing longeron is aluminum alloy.Because the density of aluminium is far below steel, intensity is higher than steel, not only Effective Raise impact strength, increase occupant's degree of safety, and because lightweight, very little on the fuel oil consumption impact that increases on the dead weight of vehicle, substantially can not increase the cost of maintaining the car.And, the aluminum alloy materials in the natural environment, owing to forming the fire coat of one deck densification at its surface energy, this fire coat can stop the intrusion of oxygen and other gas, liquid and corrode.In case this fire coat is damaged, it can carry out self-regeneration quickly in most of environment, and is namely excellent in antiseptic property.
Outstanding effect of the present invention is: the present invention is by after increasing the collision prevention girders structure, compare with traditional passenger vehicle, when vehicle ran into head-on crash, the collision prevention girders structure is energy-absorbing to greatest extent, significantly improve the especially intensity of bottom skeleton of body framwork, thereby ensured occupant's safety.Simultaneously, because the material of collision prevention girders and energy-absorbing longeron is aluminum alloy, this strength of material is high, lightweight, and is very little on the impact that the vehicle own wt produces.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.

The specific embodiment
Embodiment:
A kind of passenger vehicle collision prevention girders structure of the present embodiment such as Fig. 1～shown in Figure 5, comprises collision prevention girders 1, and collision prevention girders 1 is connected with the cross member of frame 3 of passenger vehicle by two energy-absorbing longerons 2.Wherein, collision prevention girders 1 is bolted with energy-absorbing longeron 2, and energy-absorbing longeron 2 is bolted with cross member of frame 3.Collision prevention girders 1 is formed in one, and collision prevention girders 1 is the strip of neutral straight, two ends bending.The transversal surface of collision prevention girders 1 is " day " character form structure with two hollow cavities 11.The edge of collision prevention girders 1 is provided with chamfering 12.The horizontal and vertical direction of energy-absorbing longeron 2 is provided with a plurality of energy-absorbing muscle 21, can significantly absorb energy when vehicle runs into strong collision, reduces impact force to occupant's injury.
The material of collision prevention girders 1 and energy-absorbing longeron 2 is aluminum alloy.Because the density of aluminium is far below steel, intensity is higher than steel, not only Effective Raise impact strength, increase occupant's degree of safety, and because lightweight, very little on the fuel oil consumption impact that increases on the dead weight of vehicle, substantially can not increase the cost of maintaining the car.And, the aluminum alloy materials in the natural environment, owing to forming the fire coat of one deck densification at its surface energy, this fire coat can stop the intrusion of oxygen and other gas, liquid and corrode.In case this fire coat is damaged, it can carry out self-regeneration quickly in most of environment, and is namely excellent in antiseptic property.
The present embodiment is compared with traditional passenger vehicle by after increasing the collision prevention girders structure, and when vehicle ran into head-on crash, the collision prevention girders structure is energy-absorbing to greatest extent, has significantly improved the especially intensity of bottom skeleton of body framwork, thereby ensures occupant's safety.Simultaneously, because the material of collision prevention girders and energy-absorbing longeron is aluminum alloy, this strength of material is high, lightweight, and is very little on the impact that the vehicle own wt produces.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
