Abstract
The utility model discloses a front seat installation rear beam structure, including front seat installation rear beam assemblies formed by welding a seat left bracket (1), a front seat rear beam (2) and a seat right bracket (3) in sequence. The assemblies are welded with the front floor. The other end of the seat left bracket (1) is welded with the threshold. Two front seat installation rear beam assemblies are arranged symmetrically left and right at the installation position behind the front driver seat and the front passenger seat and a middle passage reinforcing board (6) connected with the floor board is arranged between the left and right front seat installation rear beam assemblies. The front seat installation rear beam with such special structure can effectively transfer the lateral collision force in the case of lateral collision, thus reducing the deformation of the floor board and lowering the damage to the driver and the passenger to the maximum. The inclination of the upper surface of the front seat rear seat makes the rear passengers feel more comfortable.
Description
Technical field
The utility model relates to a kind of automotive body structure, and the vehicle body front chair that especially relates to a kind of manned vehicle is installed the after cross member structure.
Background technology
Nowadays automobile has been come into huge numbers of families as the important vehicle, and the safety of automobile and traveling comfort are more and more valued when people purchase car.Development along with automotive electronic technology, automobile vendor through a series of such as desiring the compact form safety strap, the anti-locking braking system, electronic stabilization device, up-to-date technologys such as safety air bag are applied on the automobile, and meanwhile car production manufacturer is in the body drawing process, guaranteeing under certain economic situation, also improve the safety of vehicle body in collision process as far as possible, the four corners of China's urban highway shows according to statistics based on level crossing.The incidence of automobile side impact traffic accident in 1998 accounts for 31.65% of traffic accident, and serious number of injured people accounts for 30.15%, and these two indexs have all surpassed the corresponding data of head-on crash accident.
In the side impact process, for vehicle body especially car door position and position, preceding floor gross distortion, dwindled crew module's space, very easily the occupant is caused serious injury.At this situation.Manufacturer generally adopts the front chair crossbeam of profile complexity and increases part on the floor at present, perhaps adopts very thick steel plate, still, exist some such as the forming parts difficulty like this, complex manufacturing, the part condemnation factor is big, some row problems that productive costs is high.And at present general vehicle all is not have the height of seat after cross member or seat after cross member very low, so just do not have the effect of how much transmitting transverse force, floor deformation is serious before making in the side collision process, thereby influences crew module's space, very easily the occupant is caused serious injury.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of front chair that the after cross member structure is installed at problems of the prior art, its objective is by the after cross member structure of installing on the front chair and make automobile actv. conduction side impact force more in side impact, improve the safety performance of automobile, and can improve back row passenger's traveling comfort.
The technical solution of the utility model is that this a kind of front chair installation after cross member structure comprises the front chair installation rear cross beam assembly that is welded to form successively by seat left side brackets, front chair after cross member and seat right side support, this assembly and preceding floor weld together, the other end of seat left side brackets and threshold weld together.
Described front chair is installed rear cross beam assembly two, the symmetrical attachment point place that is installed in behind front-seat driver's seat and the front passenger seat, about two front chairs have middle passage brace panel to be connected in the middle of rear cross beam assemblies are installed with the floor.
The crossbeam of described front chair after cross member is that upper surface has gradient.
The highest vertical direction ultimate range of described front chair after cross member has 50mm at least.
A kind of front chair installation after cross member structure with above-mentioned special construction has the following advantages:
1, in side impact, this kind front chair is installed the after cross member structure and be can be good at transmitting side impact force, has reduced the distortion on floor, thereby realizes farthest reducing the injury that driver and crew are subjected in the car.
2, because the crossbeam of front chair after cross member is the shape that upper surface has constant slope, make the upper surface of crossbeam and floor have a certain degree, improved back row occupant's traveling comfort.
3, this is simple in structure, low cost of manufacture.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 installs the structural representation of rear cross beam assembly for front chair.
Fig. 2 is the A-A schematic cross-section that front chair shown in Figure 1 is installed after cross member.
Preceding floor force-bearing situation scheme drawing when Fig. 3 is side impact.
Fig. 4 is a back row occupant sitting posture scheme drawing.
In Fig. 1～4,1: the seat left side brackets; 2: the front chair after cross member; 3: seat right side support; 4: chair mounted point brace panel; 5: front chair is installed front cross rail; 6: middle passage brace panel; 7: threshold; 8: front chair is installed left back crossbeam assembly; 9: front chair is installed right back crossbeam assembly; 10: preceding floor body.
The α angle is front chair after cross member dip plane and the formed angle of horizontal surface; H is the maximum height difference of front chair after cross member vertical direction.
The specific embodiment
By Fig. 1～4 combinations as can be known, this front chair is installed the after cross member structure and is comprised the front chair installation rear cross beam assembly that is welded to form successively by seat left side brackets 1, front chair after cross member 2 and seat right side support 3, this assembly and preceding floor are spot-welded together, the other end of seat left side brackets 1 and threshold 7 are spot-welded together, all are welded with chair mounted point brace panel 4 on seat left side brackets 1 and the seat right side support 3.This front chair is installed rear cross beam assembly two, after cross member 8 and the right after cross member 9 of installing of front chair are installed in a front chair left side, the symmetrical attachment point place that is installed in behind front-seat driver's seat and the front passenger seat, about two front chairs have middle passage brace panel 6 to be connected in the middle of rear cross beam assemblies are installed with the floor, the crossbeam of front chair after cross member 2 is that upper surface has gradient, can make back row passenger's very natural the putting thereon of pin like this, increase back row occupant's traveling comfort.
The height that front chair is installed after cross member has, than the vehicle height that the chair mounted after cross member is generally arranged, diff-H at its vertical direction can reach 50mm at least, transmit in the power process in side impact like this, the side impact force at place, preceding floor is mainly divided at front chair front cross rail 5 and front chair after cross member and is located for 2 liang to transmit.Avoided place, preceding floor to have only the front chair front cross rail to transmit most of side impact force, this structure will make the distortion of front chair front cross rail also smaller, and floor deformation is not very big before making, thus actv. protection driver and crew.Under the prerequisite that satisfies the collision requirement, the material that also can suitably reduce front chair front cross rail panel beating is thick, to alleviate the weight of vehicle body, further reduces oil consumption, has reduced use cost like this.
