Description
Technical field
The utility model relates to technical field of automobile parts, is specifically related to automobile rear cross beam assembly structure.
Background technology
Before Two decades years, car front/rear collision bumper is based on metallic material, rivets or weld together with chassis side rail, and having one section of larger gap with vehicle body, seems the parts added up.Along with the development of auto-industry, Federal bumper has also moved towards on the road of innovation as a kind of important safety device.The car front/rear collision bumper of today, except keeping original defencive function, also will be pursued harmonious and unified with car body moulding, the lightweight of pursuit itself.
First crossbeam at the rear bumper rear of automobile, effect has collision safety needs, the effect of the waveform that has some improvement, if do not have beam structure during auto against, during collision, waveform change can be very violent, and injury values is very high.
Utility model content
In order to solve the problems of the technologies described above, what the utility model adopted is to provide following technical scheme:
Automobile rear cross beam assembly structure, is made up of left and right driving steel pipe, after cross member body and bolted fittings, and left and right driving pipe is 90 ° of knuckle bend pipes, L-shaped, and knee is arc of circle limit; It is characterized in that, after cross member body side internal edge is provided with rectangular slits, and overall in " recessed " font, the knuckle knee, two ends of opposite side external margin is cambered surface, about after cross member body two edges top symmetry stretch out connecting strap laterally; And after cross member body is provided with projection near the face of external margin, shape is consistent with edge shape, left and right driving pipe, from the negative in the projection of inlay card on after cross member body, the external margin of after cross member body is provided with two vertical fasteners, is separately positioned on two ends, left and right; The two ends of left end fastener are provided with screw, and top is provided with rectangular slits, and the upper left corner of left end fastener is acute angle, and the lower right corner is provided with arc incision; Be provided with " convex " shape otch in the middle part of the right of right-hand member fastener, otch two ends are provided with screw, and the upper left corner of right-hand member fastener is arc corner cut, and the upper right corner is acute angle, is provided with rectangular slits on the right of acute angle; Bolted fittings corresponding nested enter in the screw that is provided with of fastener.
Preferred as technique scheme, on after cross member body, projection lower end is provided with multiple rectangle and cracks mouth.
The automobile rear cross beam assembly structure that the utility model provides, structure is simple and installation is firm, and use reliable, cost is lower.
Accompanying drawing explanation
