Abstract

The utility model relates to a vehicle body collision energy absorbing structure. The vehicle body collision energy absorbing structure comprises a front longitudinal beam, a wheel casing installed on the lateral side of the front longitudinal beam, a front baffle installed at the rear end of the front longitudinal beam and a rear longitudinal beam connected with the front longitudinal beam, and further comprises side body assemblies, a water groove arranged between the two side body assemblies and seat cross beams arranged between the side body assemblies and the rear longitudinal beam, wherein a front baffle reinforcing beam is further arranged on one side, located in a passenger compartment, of the front baffle in the width direction of the whole vehicle, and the front baffle reinforcing beam and the side body assemblies are fixed together. The vehicle body collision energy absorbing structure can improve vehicle body central collision and side collision energy absorbing protection, reduce vehicle body deformation caused by collision and be widely applied to the field of automobile body design.

Description

A kind of automobile body collision energy absorption structure
Technical field
The utility model relates to a kind of automotive body structure, relates in particular to a kind of automobile body collision energy absorption structure.
Background technology
Along with the development of auto trade, the safety performance of automobile more and more receives everybody concern, is also the index of weighing a car Combination property.For passive security, size and the direction of the crumple of vehicle body distortion are the key factors that affects passenger safety, so the structure design of car load vehicle body is most important,
As Chinese Patent Application No. 201020667795.9 discloses a kind of automobile side surface collision safety structure, belong to automobile technical field.It has solved existing automobile due to its sidepiece globality strength weak, thereby causes driving staff's the problems such as security threat in side collision occurs.This automobile side surface collision safety structure comprises front longitudinal floor beam and driver door threshold, the driver door threshold has fixedly connected to the inner side inner panel, be provided with the floor crossmember that both are connected between front longitudinal floor beam and inner panel, floor crossmember is tabular and is vertical setting with front longitudinal floor beam, and floor crossmember is provided with some cross reinforcings.When this automobile side surface collision safety structure hits the unit body side impact, non-deformability significantly improves, and has effectively guaranteed the survival space that the occupant is essential, has improved the safety factor of car load.But can not, to automobile central collision certain energy-absorbing effect that arrives, can not improve the safety factor of automobile central collision and side impact simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of automobile body collision energy absorption structure, solves existing front apron collision deformation large, the problem that safety factor is low.
The utility model solves the technical scheme that its technical matters adopts: a kind of automobile body collision energy absorption structure, comprise front side member, and be arranged on the wheel cover of front side member side and be arranged on the front apron of front side member rear end, and the floor side member be connected with front side member; Also comprise side wall assembly, be arranged on the roof drip between two gusset assemblies, be arranged on the seat beam between side wall assembly and floor side member, the side that described front apron is positioned at the crew module also is provided with the front apron strength beam along the car load Width, and front apron strength beam two ends and side wall assembly are fixed together.
For better transmitting and absorb the central collision energy, described front apron strength beam and front side member are positioned at the same level height.
Preferably, the cross section of described front apron strength beam is " U " font structure.
Further, described front apron strength beam and front apron, side wall assembly are welded and fixed.
The beneficial effects of the utility model: described front apron strength beam can absorb the central collision energy, reduces front apron distortion, again can the absorbing side impact energy, improve in central collision and side impact the protection to occupant in the crew module simultaneously.Simultaneously, the front apron strength beam can also improve the rigidity of front body.Front apron strength beam height is identical with front side member, can better transmit the central collision energy, absorbs distortion.The front apron strength beam adopts U-shaped cross section, and the crumple energy-absorbing effect is better.
Below with reference to drawings and Examples, the utility model is described in detail.
The accompanying drawing explanation
The position graph of a relation that Fig. 1 is the front apron strength beam.
Fig. 2 is the schematic diagram of body framwork.
The specific embodiment
Embodiment: as shown in Figure 1 and Figure 2, a kind of automobile body collision energy absorption structure, comprise front side member 1, is arranged on the wheel cover 2 and the front apron 3 that is arranged on front side member 1 rear end of front side member 1 side, and the floor side member 4 be connected with front side member 1; Also comprise side wall assembly 5, be arranged on the roof drip 6 of 5 of two gusset assemblies, be arranged on the seat beam 7 of 4 of side wall assembly 5 and floor side members, described front apron 3 is positioned at crew module's a side and also welds the front apron strength beam 8 be provided with along the car load Width, and front apron strength beam 8 two ends are with together with side wall assembly 5 is welded and fixed.The cross section of described front apron strength beam 8 is " U " font structure, and material is the Baosteel Heat forming sheet material that model is BTR165.Absorb the central collision energy for better transmitting, described front apron strength beam 8 is positioned at the same level height with front side member 1.
When central collision occurs when, front side member 1 absorbs the backward rear transmission of energy, divide supplementary biography to wheel cover 2, front apron strength beam 8 and floor side member 4 three paths, front apron strength beam 8 absorption portion energy, because front apron strength beam 8 is connected with side wall assembly 5, also can the transmitting portions energy to side wall assembly 5, can effectively reduce damage and the indoor intrusion amount of front apron 3, improve passenger's safety factor.
When side impact occurs when; the energy that side wall assembly 5 absorbs is respectively from roof drip 6, front apron strength beam 8 and seat beam 7 three paths energy-absorbing transferring energies; front apron strength beam 8 absorption portion energy; dump energy is passed to the side wall assembly 5 of the other end simultaneously; reduce the deflection of vehicle body, improve the protection to passenger in the crew module.
Simultaneously, front apron strength beam 8 can effectively improve the rigidity of vehicle body.
