Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
According to an aspect of the utility model embodiment, provide a kind of body structure, comprising:
Be arranged on the collision prevention girders 1 of body structure.
One end of described collision prevention girders 1 is connected with the first energy-absorption box 2, and the other end is connected with the second energy-absorption box 3.
Described first energy-absorption box 2 is connected with the first longeron 4, and described second energy-absorption box 3 is connected with the second longeron 5.
Described first longeron 4 has the first mud guard 6, described first mud guard 6 has the first damping tower 8 of magnesium aluminum alloy material.
Described second longeron 5 has the second mud guard 7, described second mud guard 7 has the second damping tower 9 of magnesium aluminum alloy material.
Wherein, described collision prevention girders 1 comprises: the first Crashworthy plate 101 of aluminum alloy material and the second Crashworthy plate 102 of steel material, the two ends of described first Crashworthy plate 101 are corresponding with the two ends of described second Crashworthy plate 102 to be respectively connected, between described first Crashworthy plate 101 and described second Crashworthy plate 102, there is an accommodation space 103, there is in described accommodation space 103 inner supporting structure 104.
The body structure structure that the utility model embodiment provides, consider from the security standpoint of pedestrian and occupant simultaneously, its collision prevention girders 1 adopts the design of high strength steel after front aluminum alloy, and the first Crashworthy plate 101 as collision prevention girders 1 header board is aluminum alloy material, adopts aluminum alloy material, the weight of car load can be reduced, promote body lightening, and in the process of colliding, easily deformation occurs, play buffer action to by the pedestrian hit, reduce the injury to pedestrian.The second Crashworthy plate 102 as the rear plate of collision prevention girders 1 is high strength steel material, and hardness is large, and intensity is high, not yielding, in colliding, can reduce the intrusion of crew module, and then serve the protective effect to occupant.In addition, in order to strengthen the energy-absorbing effect of body structure structure further, between first Crashworthy plate 101 and the second Crashworthy plate 102 of collision prevention girders 1, inner supporting structure 104 is also provided with.
In addition, in order to promote body structure NVH (abbreviation of Noise, Vibration, Harshness) performance, the damping tower of body structure is also improved.Damping tower is used for the bumper of connecting base plate system to vehicle body, and the vibrations that in vehicle traveling process, road surface causes can be passed to vehicle body by damping tower, finally can have influence on the NVH performance of automobile.Damping tower in current automobile adopts steel usually, and the density ratio steel of magnesium aluminum alloy are little, and magnesium aluminum alloy has very large damping coefficient simultaneously, can provide good damping, namely reduces the vibrations in running car.Therefore, in the utility model embodiment, the first damping tower 8 and the second damping tower 9 adopt die-casting magnalium alloy to make, and can provide very high damping, improve body structure NVH performance.Further, because the density of magnesium aluminum alloy is low, can reduce the weight of body forward structure (i.e. engine nacelle), the center of gravity of automobile is moved forward, and this effectively can provide the tractive performance of automobile.
Optionally, the material of described inner supporting structure 104 is aluminum alloy, preferably be rolled into the aluminium alloy plate of wavy shaped configuration, crest in described wavy shaped configuration and wave trough position contact with described first Crashworthy plate 101 and the second Crashworthy plate 102 respectively, and rivet with described first Crashworthy plate 101 and the second Crashworthy plate 102.The aluminium alloy plate of wavy shaped configuration can promote the energy-absorbing effect of body structure further.In addition, can also the buffer substance such as filled rubber, fiber forced foamed material or foam in the accommodation space 103 formed between the first Crashworthy plate 101 and the second Crashworthy plate 102, further to promote the energy-absorbing effect of body structure.
Optionally, the material of described first energy-absorption box 2, second energy-absorption box 3, first longeron 4, second longeron 5 and the first mud guard 6, second mud guard 7 is steel material.Because the intensity of aluminum alloy is at about 300MPa, and on collision bang path, need to arrange high strength steel, to absorb deformation energy, personal security in protection passenger accommodation.Therefore, the material of energy-absorption box, longeron and mud guard adopts steel material, to absorb collision energy, reduces the distortion of crew module.
Optionally, first damping tower 8 of magnesium aluminum alloy material and the connection of the second damping tower 9 and steel component parts are for being spirally connected, the bolt used adopts specific coatings process, comprises bethanizing, passivation layer and barrier layer, effectively can reduce the contact corrosion because difference of potential causes in this coat system.
According to another aspect of the utility model embodiment, provide a kind of automobile, comprise body structure structure as above.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
