Further, the section of the support member is U-shape structure, and the U-shape structure edge of support member is provided with flange, described to turn over Side is connected with automobile central passage.
It is connected between the support member two ends and support beam by demountable structure.
The support beam is hollow cross.
The global shape of the support member is domes.
The support member includes support member I and support member II, the support member I and support member II include side and One bottom surface, the bottom surface of two support members is connected, and is connected sideways with automobile central passage.
The support beam both ends of the surface fit with automobile central passage surface.
The reinforcement of arch is equipped with the U-shape structure biside plate of the support member.
The demountable structure includes the project-welding nut being located on support member and the fixing hole for being located at support beam, support member Coordinated with support beam by bolt with project-welding nut and be connected.
The shape of the support member matches with automobile central passage lower surface.
The present invention compared with prior art, with advantages below:
1st, automobile central passage structure of the present invention is connected using two pieces of support member welding, is formed with certain section depth U-shaped cavity frame structure, structural strength is big, it is easy to which punching press, manufacturing cost is low, improves and shock loading is carried in side collision Ability;
2nd, by the support beam of centre gangway, a closed loop frame structure is formed it into, its bearing capacity is obtained greatly Reinforcement, can effectively prevent during side collision automobile central passage from big deformation occur, to greatest extent will be from The collision impact load that seat beam is passed over is transmitted to the non-impact side of vehicle body, has reached the side collision for improving automobile Can, improve body of a motor car Side-impact safety, and then reduce occupant's injures and deaths;
3rd, support beam is detachably connected with U-shaped cavity frame structure, facilitate the support beam of centre gangway installation and Dismounting, is easy to the installation and dismounting of discharge duct or 4-wheel driven car power transmission shaft;And it is simple in construction, it is easy to accomplish.

Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of Explanation.
As shown in Figures 1 to 5, in the automobile central passage reinforcement structure is arranged on below automobile central passage, knot is strengthened Structure includes support member and support beam, and support member includes support member I 1 and support member II 2, and support member I 1 and support member II 2 are wrapped A side and bottom surface are included, is conveniently welded sideways provided with flange with centre gangway body 6.
The underrun solder joint 5 of support member I 1 and support member II 1 welds together, and the section of support member is U-shape structure, branch The U-shape structure edge of support member is provided with the flange welded with centre gangway body 6.The side of support member I 1 and support member II 2 is all provided with Three sections of flange are equipped with, are welded respectively with the centre gangway body bottom surface contacted and two sides.
Support member I 1 and support member II 2 are connected in its underrun spot welding, form the U-shaped cavity with certain section depth Frame structure.The shape of U-shaped cavity frame structure and the surface of the centre gangway contacted with it match, and by U-shaped Flange and the welding of centre gangway lower surface on support member are connected.
The side of support member I 1 and support member II 2 is equipped with the reinforcement of arch, increases the bending resistance of support member, lifting The bearing capacity of centre gangway.
Support member two ends are connected to form closed loop frame structure by support beam 3, and closed loop frame structure is entreated logical in the car The seat beam of position and automobile aligns on road.It is connected between support member two ends and support beam 3 by demountable structure.
Demountable structure includes the project-welding nut 4a being located on support member and the fixing hole for being located at support beam, and bolt 4b is worn The fixing hole crossed in support beam is engaged with project-welding nut on support member, and support member and support beam 3 are connected.Support Crossbeam 3 is detachably connected with U-shaped cavity frame structure, facilitates the installation and dismounting of the support beam of centre gangway, is easy to exhaust The installation and dismounting of pipeline or 4-wheel driven car power transmission shaft.
By the support beam 3 of centre gangway, a closed loop frame structure is formed it into, its bearing capacity is obtained greatly Strengthen, can effectively prevent that big deformation occurs in automobile central passage during side collision, to greatest extent will be from seat The collision impact load that chair crossbeam is passed over is transmitted to the non-impact side of vehicle body, has reached the side collision performance for improving automobile, Improve body of a motor car Side-impact safety.
Support beam is the hollow crossbeam with certain section depth, and its cross sectional shape and wall thickness can be set as needed Put.Support beam both ends of the surface fit with automobile central passage surface.Support beam is arranged on the lower section of support member, forms closed loop Cavity frame structure, lift structure intensity.
The shape of support member matches with automobile central passage lower surface, and the global shape of support member is domes.It is anti- Deformability is strong, lifts the bearing capacity of side.
In side collision, collision impact load is delivered to centre gangway by B posts, threshold and seat beam, above-mentioned U-shaped Frame structure serves the effect of support centre gangway, improves resistance of the centre gangway in side collision, can make collision Load is efficiently transferred to vehicle body non-collision side.
Centre gangway reinforcement structure is provided with the support beam of centre gangway immediately below U-shaped framework structure, and passes through spiral shell Bolt and the connection of U-shaped framework structure, form it into a closed loop frame structure, the relatively conventional U-shaped support member of single-piece centre gangway, Its bearing capacity has obtained great reinforcement.In side collision, the shock loading passed over from seat beam is very big one Divide and transmitted by above-mentioned centre gangway support beam, remainder is transmitted by U-shaped framework structure, and therefore, centre gangway is in side The deformation of very little can be kept even indeformable in the collision of face.By setting above-mentioned centre gangway reinforcement structure part, collision can be carried Lotus is effectively delivered to vehicle body non-collision side by threshold, seat beam and centre gangway, in side collision to greatest extent Crew module's integrality is kept, the side collision performance of automobile is improved.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way Limitation, as long as employ the present invention design and technical scheme carry out various unsubstantialities improvement, or it is not improved will The design and technical scheme of the present invention directly applies to other occasions, within protection scope of the present invention.
