Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figures 1 to 5, this automobile central passage is strengthened vibrational power flow and is entreated in the car in below passage, strengthen structure and comprise strut member and supporting traverse, strut member comprises strut member I 1 and strut member II 2, strut member I 1 and strut member II 2 include a side and bottom surface, and side is provided with flange and conveniently welds with centre gangway body 6.
Underrun solder joint 5 weld together of strut member I 1 and strut member II 1, the cross section of strut member is U-shaped structure, and the U-shaped structural edge of strut member is provided with the flange welded with centre gangway body 6.The side of strut member I 1 and strut member II 2 is provided with three sections of flange, welds respectively with contacted centre gangway body bottom surface and two sides.
Strut member I 1 and strut member II 2 are connected in its underrun spot welding, form the U-shaped cavity frame structure with certain section depth.The shape of U-shaped cavity frame structure and the surface of centre gangway contacted with it match, and are connected by the flange on U-shaped strut member and the welding of centre gangway lower surface.
The side of strut member I 1 and strut member II 2 is equipped with the reinforced rib of arch, increases the resistance to bending of strut member, promotes the load-carrying capacity of centre gangway.
Strut member two ends are connected to form closed loop framed structure by supporting traverse 3, and closed loop framed structure entreats the seat beam of position and automobile on passage to align in the car.Be connected by demountable structure between strut member two ends with supporting traverse 3.
Demountable structure comprises the project-welding nut 4a be located on strut member and the fixed orifice being located at supporting traverse, and bolt 4b matches with project-welding nut on strut member through the fixed orifice on supporting traverse, strut member and supporting traverse 3 is coupled together.Supporting traverse 3 is detachably connected with U-shaped cavity frame structure, facilitates installation and the dismounting of the supporting traverse of centre gangway, is convenient to installation and the dismounting of gas exhaust duct or 4-wheel driven car transmission shaft.
By the supporting traverse 3 of centre gangway, it is made to form a closed loop framed structure, its load-carrying capacity is strengthened greatly, can prevent automobile central passage in side collision process from occurring large distortion by actv., to greatest extent the collision impact load passed over from seat beam is transmitted to vehicle body non-impact side, reach the side collision performance improving automobile, improve auto body Side-impact safety.
Supporting traverse is the hollow crossbeam with certain section depth, and its cross sectional shape and wall thickness can be arranged as required.Supporting traverse both ends of the surface and automobile central passage surface fit.Supporting traverse is arranged on the below of strut member, forms closed loop cavity frame structure, lift structure intensity.
Shape and the automobile central passage lower surface of strut member match, and the global shape of strut member is arch configuration.Non-deformability is strong, promotes the load-carrying capacity of side.
In side collision, collision impact load is delivered to centre gangway by B post, threshold and seat beam, above-mentioned U-shaped framed structure serves the effect supporting centre gangway, improves the resistibility of centre gangway in side collision, impact load can be made effectively to be delivered to vehicle body non-collision side.
The supporting traverse that structure is provided with centre gangway immediately below U-shaped framed structure strengthened by centre gangway, and be connected with U-shaped framed structure by bolt, make it form a closed loop framed structure, relatively traditional U-shaped strut member of single-piece centre gangway, its load-carrying capacity obtains great reinforcement.In side collision, the impact load passed over from seat beam is greatly by the transmission of above-mentioned centre gangway supporting traverse, remainder is transmitted by U-shaped framed structure, and therefore, the distortion that centre gangway can keep very little in side collision is not even out of shape.Strengthening framing member by arranging above-mentioned centre gangway, impact load can be made effectively to be delivered to vehicle body non-collision side by threshold, seat beam and centre gangway, in side collision, keep crew module's integraty to greatest extent, improving the side collision performance of automobile.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technical scheme are carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
