Abstract
The utility model discloses an automotive rear floor anti-collision beam structure. The automotive rear floor anti-collision beam structure can overcome the disadvantage that large damage are likely to occur on the back seat occupants in the prior automobiles due to large automobile body deformation resulting from the arrangement of one single beam body on the rear floor of an automobile when collision, particularly lateral collision, occurs. The automotive rear floor anti-collision beam structure is connected with the rear floor and comprises a beam body. The automotive rear floor anti-collision beam structure is characterized in that the beam body has a split structure including an upper beam and a lower beam parallel to each other, and the upper beam and the lower beam are respectively connected with the corresponding upper surface and the lower surface of the rear floor.
Description
Technical field
The utility model relates to the collision protection structure on a kind of automobile, relates in particular to the crashproof beam structure of a kind of automobile rear floor.
Background technology
In order to reduce the deadweight of automobile, the vehicle body of automobile generally is made thinner relatively, and this causes the intensity of vehicle body lower, and when automobile bumped, the deformation quantity of vehicle body can be very big, and this personal safety meeting to the occupant brings bigger hidden danger.For increasing the crashworthiness of automobile self, on automobile rear floor in the position of back seat, all need to be provided with crashproof crossbeam, this crashproof crossbeam runs through the whole Width of vehicle body, its two ends respectively with automobile on set left and right rear shock absorber adapter plate connect as one.Like this, bump at automobile, when particularly broadside impact taking place, crashproof crossbeam can effectively reduce the deflection of vehicle body at the back seat place, in the hope of protecting back row occupant's safety.The crashproof crossbeam in back floor of existing automobile is only for being arranged on a monomer crossbeam on the lower surface of floor, back, for reducing the deadweight of automobile, this monomer crossbeam can not be made very big, when automobile generation side impact, cause the upwards distortion of rear portion vehicle body easily, and deflection is big, easily back row personnel is damaged.
Summary of the invention
For overcoming the above-mentioned defective that the existing crashproof crossbeam of automobile rear floor is had; the utility model technical issues that need to address: provide a kind of later-model automobile rear floor crashproof beam structure; this beam structure can increase the intensity of automobile rear floor position effectively; when automobile generation broadside impact, can provide the better protect effect for back row's occupant.
For solving the problems of the technologies described above, the technical solution of the utility model: the crashproof beam structure of a kind of automobile rear floor, be connected on the floor, back, comprise cross-beam body, it is characterized in that cross-beam body is a split-type structural, it comprises entablatrance and cross sill, upper and lower crossbeam is parallel, and is connected on the corresponding upper and lower surface, floor, back.Upper and lower crossbeam generally is that the mode by welding is connected on the back floor of automobile, and upper and lower crossbeam is identical in the position of back on the floor, their two ends all with automobile on set left and right bumper adapter plate connect as one.
As preferably, described entablatrance is the tabular body that truncation surface is flute profile, and entablatrance is fastened on the upper surface on floor, back.Entablatrance is the tabular body folding forming, helps under the prerequisite that alleviates this body weight of entablatrance, guarantees the intensity of entablatrance, and the entablatrance of this structure can absorb the Impact energy of a part when automobile bumps.
As preferably, described entablatrance is provided with the flange that stretches out towards its outside along the place, both sides of the edge of its length direction, and the surface of this flange fits together with the upper surface on floor, back.The flange that is provided with is fitted with the back floor upper surface, can improve the connectivity robustness between entablatrance and the floor, back.
As preferably, described cross sill is the L-shaped tabular body of truncation surface, and cross sill is fastened on the lower surface on floor, back.Cross sill is that tabular body is pulled the type of building up, and helps under the prerequisite that alleviates this body weight of cross sill, guarantees the intensity of cross sill, and the cross sill of this structure can absorb the Impact energy of a part when automobile bumps.
As preferably, described cross sill is provided with the shirt rim of stretching out towards its outside along the place, both sides of the edge of its length direction, and the surface of this shirt rim fits together with the lower surface on floor, back.Fitting with the lower surface on floor, back in the shirt rim, has improved the connectivity robustness between cross sill and the floor, back effectively.
As preferably, described cross sill is the L-shaped tabular body of truncation surface, and the truncation surface that upper and lower crossbeam is connected on the floor, back constitutes an approximate rectangle.The truncation surface of upper and lower crossbeam constitutes an approximate rectangle, the opening size size of upper and lower crossbeam is consistent basically, upper and lower crossbeam is this structure, being convenient to floor, sweeping back passes between the upper and lower crossbeam, have the cavity that holds floor behind the bending between the upper and lower crossbeam, made things convenient for being connected between upper and lower crossbeam and the floor, back.
Therefore, the beneficial effects of the utility model:
Because described crashproof crossbeam is to be made of split type upper and lower crossbeam; and upper and lower crossbeam is corresponding in the position on floor, back; improved the intensity of crashproof crossbeam; when automobile generation broadside impact; help reducing the deflection that vehicle body is taken place because of collision; protect automobile rear occupant's personal safety effectively, improved the travel safety of automobile.。
Description of drawings
Accompanying drawing 1 is the running condition reference diagram of the crashproof beam structure of the utility model automobile rear floor.
Accompanying drawing 2 is amplification views that cross-beam body and floor, back link together.
The specific embodiment
See accompanying drawing, the crashproof beam structure of the utility model automobile rear floor packing cross-beam body 2, these cross-beam body 2 automobile fittings link together with the back floor 6 of automotive interior after on the automobile, and cross-beam body 2 is in the position of automobile rear seat in the position of automobile.Cross-beam body 2 is applied on the Width of whole automobile, and right back bumper adapter plate 1 set on its end and the automobile connects as one, and left back bumper adapter plate 3 set on the other end and the automobile connects as one.
Cross-beam body 2 is a split-type structural, it comprises entablatrance 4 and the cross sill 7 that is arranged in parallel, upper and lower crossbeam is welded on respectively on relative two surfaces of floor 6 corresponding positions, back, the both ends of upper and lower crossbeam respectively with above-mentioned automobile on set bumper adapter plate connect as one.
