Specific embodiment
Below in conjunction with specific embodiment, one body of a motor car skeleton of the present invention is further described, wherein direction from left to right, edge is longitudinal and longeron direction, along being laterally and crossbeam direction by vertical paper direction outside to inside, be vertically and vertical beam direction along direction from top to bottom.
As shown in Figure 1-2, a kind of body of a motor car skeleton of the present invention, including front cabin skeleton 1, battery stateroom skeleton 2, deck store skeleton 3 and roof rail 14;Described front cabin skeleton 1 rear end is fixing with the front end of described battery stateroom skeleton 2 to be connected, the rear end of described battery stateroom skeleton 2 is fixing with the front end of described deck store skeleton 3 to be connected, and the rear and front end of described roof rail 14 is fixed be connected with described front cabin skeleton 1 and described deck store skeleton 3 respectively;The postmedian of described battery stateroom skeleton 2 is provided with battery stateroom front beam 8 and battery stateroom rear cross beam 9, and the both sides of described battery stateroom skeleton 2 are equipped with jack stringer 6 and interior beam 7;The two ends of described jack stringer 6 and described interior beam 7 are fixed be connected with battery stateroom front beams 8 and battery stateroom rear cross beam 9 respectively;Described interior beam 7 is positioned at the inner side of described jack stringer 6, and described interior beam 7 one end tilts to described jack stringer 6 one end, forms acute angle between described interior beam 7 and described jack stringer 6;The described interior beam 7 of both sides and battery stateroom front beam 8 and battery stateroom rear cross beam 9 define the fixed frame being available for the hollow that battery bag loads from the bottom to top, and described battery bag is fixing with described fixed frame to be connected.So, independent battery stateroom skeleton 2 structure, facilitate layout and the installation of battery bag;Battery bag loads from lower to upper from fixed frame, and battery bag can be fastened by bolts on the Zhou Bianliang of fixed frame;Fixed frame is the quality that hollow structure reduces battery stateroom skeleton 2, it is ensured that the lightweight of integral body.Meanwhile, battery stateroom skeleton 2 is positioned at car load centre position, front cabin skeleton 1 and deck store skeleton 3 respectively before and after vehicle body;Due to the setting of front cabin skeleton 1 and deck store skeleton 3 structure in normal impact, collision impact is served the effect of buffering, thus reduce automobile central collision, after touch time impulsive force to battery bag, thus improve the security performance of battery bag.Described interior beam 7 one end tilts to described jack stringer 6 one end, forms acute angle between described interior beam 7 and described jack stringer 6.So, a stable class triangular structure is defined between interior beam 7, jack stringer 6 and battery stateroom rear cross beam 9.Owing to triangular structure has stability, so that battery stateroom skeleton 2 not only meets the firm installation of battery bag;Also vehicle body is played the effect of stable support, when reducing vehicle side impact, the deformation of body structure, battery bag impulsive force is served cushioning effect.
Referring to accompanying drawing 1-2, a kind of body of a motor car skeleton of the present invention is on the basis of technique scheme, may is that it is preferred that technical scheme it may also is that being respectively provided on two sides with of described front cabin skeleton 1 reaches longeron outside before described front cabin skeleton 1, two described longerons are fixedly installed horizontal Guard Assy 4;The longeron that being respectively provided on two sides with of described rear deck skeleton is outside after reaching described rear deck skeleton, two described longerons are fixedly installed horizontal Grard Assy 5.So, reach front cabin skeleton 1 respectively due to Guard Assy 4 and Grard Assy 5 and deck store skeleton 3 is outside, make battery stateroom skeleton 2 positional distance Guard Assy 4 and Grard Assy 5 all farther out, collision is served cushioning effect by ultimate range, decrease the danger come to battery band in an impact.Further technical scheme is it may also is that the height of described Guard Assy 4 and described Grard Assy 5 is above the height of described fixed frame.So, when vehicle generation central collision and after touch time, front cabin skeleton 1 and deck store skeleton 3 deform, and have slackened the direct impact to battery bag, even explode thus avoiding battery bag to catch fire because of collision.
Referring to accompanying drawing 1-2, a kind of body of a motor car skeleton of the present invention is on the basis of technique scheme, may is that and described battery stateroom skeleton 2 is integrated with front floor stand beam 10 and seat frame 11, described seat frame 11 is fixed on described interior beam 7 and the described battery stateroom rear cross beam 9 of both sides, and the two ends of described front floor stand beam 10 are fixed with described battery stateroom front beam 8 and front floor crossmember 15 respectively.So, by battery stateroom integrated seat framework 11 and front floor stand beam 10, the overall simplification design of body frame, improve the integrated level of battery stateroom skeleton 2;Integrated adding connects and supports simultaneously, improves stability and the reliability of integral body skeleton.
Referring to accompanying drawing 1-2, a kind of body of a motor car skeleton of the present invention is on the basis of technique scheme, may is that the both sides of the both sides of the front end of described battery stateroom and rear end are not provided with front vertical beam 12 and rear vertical beam 13, described front vertical beam 12 and described rear vertical beam 13 are fixing with the front and rear of described roof rail 14 respectively to be connected.So, by described front vertical beam 12 and described rear vertical beam 13, roof rail 14 is served the effect of support, adds the stability of roof rail 14.Further technical scheme is it may also is that described rear vertical beam 13 tilts to be fixed on described jack stringer 6, and the angle between described rear vertical beam 13 and described jack stringer 6 is acute angle.So, the rear vertical beam 13 being obliquely installed avoids the position of described fixed frame self-contained battery bag, and battery bag can visualize and be fixed, it is simple to fastening and the adjustment to battery bag.Further technical scheme is it may also is that described front cabin skeleton 1, described battery stateroom skeleton 2 and described deck store skeleton 3 all adopt aluminium section bar to make.So, the body frame structure for automotive of aluminium section bar, reduce complete vehicle quality, it is achieved that car load lightweight;Decrease the loss of energy, thus improve duration performance.It is preferred that technical scheme can also be: described fixing be connected by being welded and fixed or rivet fixing.This way it is ensured that the stiffness and strength of body frame, meanwhile, fully use production technology of the prior art, simplified the design of production line, reduce production cost.
Above-mentioned only a kind of specific embodiment in the present invention is illustrated, but can not as protection scope of the present invention, every equivalence change done according to the design spirit in the present invention or modify, all it is deemed to fall protection scope of the present invention.
