Abstract
The invention discloses a back installation beam assembly of a front row seat of a car. The back installation beam assembly comprises a back middle installation support of the front row seat, a back outside installation support of the front row seat and a back installation beam of the front row seat. A reinforcing piece is arranged under an upward bending position at the end, close to a threshold, of the back installation beam of the front row seat. Turning edges welded with a car front floor are arranged at the lower ends of the two side walls of the reinforcing piece. The outer surface of the upper end of the reinforcing piece is welded with the lower surface of the upper end of the back installation beam of the front row seat. The lower surfaces of the turning edges of the lower ends of the two side walls of the back installation beam of the front row seat are welded with the upper surfaces of the turning edges of the lower ends of the two side walls of the reinforcing piece. The back installation beam assembly of the front row seat of the car can transmit side collision force better, improve collision performance, reduces side impact inpouring amount and front floor deformation amount and better ensure the safety of passengers.
Description
Technical field
The present invention relates to the parts of automobile, more specifically to crossbeam assembly is installed after a kind of car front seat.
Background technology
Existing economy car, the both sides at its front-row seats rear portion be arranged on respectively after front-row seats in after mounting bracket and front-row seats on outer mounting bracket, after existing front-row seats, the mounting structure of mounting bracket and vehicle body is as shown in Figure 7: after front-row seats mounting bracket comprise after front-row seats in outer mounting bracket 5 after mounting bracket 3 and front-row seats, in after front-row seats, after mounting bracket 3 and front-row seats, outer mounting bracket 5 is arranged on respectively on automobile front floor 7, form two separate rear attachment points of front-row seats, in after front-row seats, on mounting bracket, be provided with reinforcement 4, in after this reinforcement 4 and front-row seats, mounting bracket overlap joint extends to longitudinal beam welding limit place under front floor, with front floor, longitudinal beam welding under front floor.The structure at this front-row seats rear portion can make rear row occupant foot well large, ride comfort, but it is unfavorable for side impact power transmission, side impact poor-performing, in the time there is side impact, front floor and chair mounted point deformation are relatively large, easily cause seat to tilt, and increase occupant injury.
The patent No. is that 200910104629 patent discloses " a kind of rear mounting structure of front-row seats of vehicle ", in after front-row seats, be welded to connect one between mounting bracket outside after mounting bracket and front-row seats crossbeam has been installed, form an integral support and be weldingly fixed on automobile front floor, this structure has improved side impact performance to a certain extent.In the time there is side impact, side impact force is collided support reinforcing part by side threshold and is fully passed to after front-row seats, after outer mounting bracket and front-row seats, crossbeam is installed, the bending part of crossbeam is now installed easily because impact force is larger after front-row seats after outer mounting bracket and front-row seats, be out of shape and produce, seat is tilted, thereby occupant is damaged.
Summary of the invention
After the object of this invention is to provide a kind of car front seat, crossbeam assembly is installed, to transmit better side impact force, is promoted collision performance, reduce side impact impouring amount and front floor deformation amount, ensure better occupant's safety.
Crossbeam assembly is installed after car front seat of the present invention, mounting bracket in comprising after front-row seats, after front-row seats, after outer mounting bracket and front-row seats, crossbeam is installed, it is that cross-sectional plane is inverted U-shaped structure that crossbeam is installed after this front-row seats, one end at it near threshold is provided with the upwards installation portion of bending, after front-row seats, outer mounting bracket is by welding flanging welded on this installation portion, crossbeam is installed after front-row seats near being provided with reinforcement below the upwards bending place of that end of threshold, this reinforcement is Troffer, it is inverted U-shaped that its cross-sectional plane is, the lower end of its two side is provided with the flange with automobile front floor welding, the lower surface welding of crossbeam upper end is installed after the outside face of its upper end and front-row seats, the lower surface of flange of lower end, crossbeam two side and the welding of the upper surface of the flange of lower end, reinforcement two side are installed after front-row seats.
The middle part of described reinforcement upper end, along being laterally provided with concave bar, has further increased the intensity of reinforcement.
On described reinforcement, the height of the sidewall of close headstock is higher than the height of the sidewall away from headstock, to meet rear row's occupant's step space.
In after described front-row seats, mounting bracket is positioned at the other end that crossbeam is installed after front-row seats, and crossbeam is installed after front-row seats is combined as a whole.Merge into a sheet metal component by crossbeam being installed after middle mounting bracket and front-row seats after front-row seats, reduced welding cost, ensured better again the precision of front-row seats attachment point.
Crossbeam assembly is installed after front-row seats of the present invention; owing to having additional reinforcement; in the time of automobile generation side impact; impact force from collision support reinforcing part power transmission face is passed to front-row seats after cross member and front-row seats outside mounting bracket; outside after front-row seats after cross member and front-row seats, mounting bracket bending part passes through reinforcement; decompose side impact force, the outer mounting bracket shape that remains unchanged after front-row seats after cross member and front-row seats while making side impact, the protection to occupant while having strengthened automobile side impact.
