Abstract
The utility model discloses an automobile rear crossbeam, and aims to solve the problems that conventional automobile rear crossbeams are inconvenient to demount and replace and are high in manufacturing costs. The automobile rear crossbeam comprises a strip-shaped inner plate and an outer plate connected on the inner plate, wherein a cross section of the outer plate is U-shaped, edges along two length directions of the outer plate are connected with the edges along two length directions of the inner plate, two ends of the inner plate are provided with connection supports, and both the two ends of the inner plate and the connection supports are provided with connection holes, with axes of the connection holes in the inner plate and in the connection supports overlapped with each other. The rear crossbeam is connected on a vehicle body via bolts. Because few lap joints are disposed between the cross beam and the vehicle body and the cross beam is connected with the vehicle body in a dismountable manner, the rear crossbeam is convenient to dismount and replace if being deformed after absorbing energy when an automobile is crushed from behind,. Besides, the rear crossbeam is simple in overall structure and low in manufacturing costs.
Description
Technical field

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of automobile after cross member comprises inner panel, is connected the outside plate on the inner panel; Inner panel is elongated; The cross section of outside plate takes the shape of the letter U, and the edge of two length directions of outside plate is connected to the edge of two length directions of inner panel, and the two ends of inner panel are provided with the connection support; The two ends of inner panel and connect on the support and be equipped with connecting bore, and the connecting bore on the said inner panel be connected support on the connecting bore dead in line.The outside plate of U-shaped is connected on the inner panel, constitutes a cavity body structure, has the effect of energy-absorbing.Outside plate and inner panel link together the automobile after cross member that constitutes through bolted connection on car body, the connection location of bolt is at the two ends of inner panel, the connecting bore on bolt passes inner panel and is connected support is detachably connected on the car body.After cross member distortion energy-absorbing when bumping after automobile takes place, because the lap position of after cross member and car body is less, after cross member is detachably connected on the car body through bolt again, after cross member distortion back dismounting and change is convenient.And the integral structure of after cross member is simple, low cost of manufacture.
As preferably, be fixedly connected with two symmetrically arranged connecting panels on the inner panel, connecting panel is provided with mounting hole.Through bolt connecting panel is connected on the car body, has increased the Joint strenght of after cross member and car body, their reliable and stable that links together.
As preferably, two laterally inclined settings of U-shaped outside plate.Be respectively equipped with several energy-absorbing holes on two sides of U-shaped outside plate.The two sides inclination of outside plate and the energy-absorbing hole on the outside plate all help the crumple distortion of outside plate, increase energy-absorbing effect.The weight that the energy-absorbing hole has also alleviated after cross member has reduced material, has reduced cost.
As preferably, the edge of inner panel length direction is provided with the flange away from the outside plate direction, and the edge joint weld of outside plate is connected on the flange of inner panel.Flange has made things convenient for being connected of inner panel and outside plate.
As preferably, the connection location of inner panel and outside plate both sides is arranged with four pairs of grooves.When having other parts to be connected with after cross member on the car body, groove has made things convenient for their connection.
As preferably, be provided with some energy-absorbing grooves outside the bottom surface of U-shaped outside plate.The energy-absorbing groove increases the energy-absorbing effect of outside plate.
As preferably, connect support and be concave shape, comprise two sides and a bottom surface, a lateral edges of bottom surface stretches out triangular in shape.The after cross member that the connection support is connected car body back wall skirtboard connects in the groove, connects support Design and becomes this structure, has made things convenient for it to be connected the connection of groove with after cross member.
Compared with prior art, the beneficial effect of the utility model is: dismounting and change is convenient behind (1) automobile after cross member collision deformation; (2) automobile after cross member energy-absorbing effect is good, and is simple in structure, low cost of manufacture.
