Preferably, the cross beams are two metal cross beams horizontally arranged, and a circular groove matched with the rubber pier is formed in one side, close to the rubber pier, of the cross beams.

Preferably, the number of the rubber piers is six, every two rubber piers are in one group, and each group of rubber piers is respectively arranged in the circular grooves on the surfaces of the two metal cross bars of the cross beam.

Preferably, the rubber pier is integrally in a fusiform shape, two ends of the rubber pier are provided with planes, the diameters of the two ends of the rubber pier are smaller than the diameter of the central part, and two ends of the rubber pier are provided with plane rubber pads.

Preferably, the number of the connecting plates and the mounting seats is three, and each connecting plate is arranged opposite to the mounting seat.

Preferably, each group of rubber piers and a pair of connecting plates and mounting seats which are oppositely arranged are arranged on the same plane.

Preferably, a groove matched with the buffer material is formed in one side, close to the buffer material, of the outer plate, and one side, far away from the rubber pier, of the buffer material is arranged in the groove.

Preferably, the connecting bolt passes through the outer plate, the buffer material, the connecting plate and the mounting seat, and a gasket, a spring gasket and a bolt are arranged layer by layer on one side of the connecting bolt, which is close to the mounting seat.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the connecting plate is arranged on one side of the buffer material, which is close to the cross beam, and the rubber pier is arranged between the connecting plate and the cross beam, so that the buffer material deforms when the outer plate receives impact force, and moves towards the cross beam when the impact force is greater than the upper stress limit of the buffer material, and the connecting plate is pushed in the moving process to uniformly transfer the force to the rubber pier, so that the rubber pier deforms, the buffer material is enabled to fail, part of external impact force can be absorbed and relieved, and the safety of vehicles and drivers is increased.

Detailed Description

In order that the manner in which the above recited features, objects and advantages of the present utility model are obtained, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Based on the examples in the embodiments, those skilled in the art can obtain other examples without making any inventive effort, which fall within the scope of the utility model.

Specific embodiments of the present utility model are described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1 to 4, an automobile bumper buffer structure is assembled by the following components:

and (3) assembly description: firstly, the cross beam 2 is mounted on the surface of the mounting seat 1, then the rubber pier 3 is mounted on one side, far away from the mounting seat 1, of the cross beam 2, the connecting plate 4 is mounted on one side, far away from the mounting seat 1, of the rubber pier 3, then the buffer material 5 is mounted on the other side of the connecting plate 4, the outer plate 6 is mounted on one side, far away from the connecting plate 4, of the buffer material 5, and finally the connecting bolt 7 is mounted inside the outer plate 6.

Description of working principle: firstly, when the automobile bumper receives impact, the outer plate 6 moves towards the direction of the connecting bolt 7 to push the buffer material 5 to deform, when the impact force is larger than the upper stress limit of the buffer material 5, the buffer material 5 moves towards the direction of the cross beam 2, the connecting plate 4 is pushed in the moving process, the connecting plate 4 uniformly transmits the force to the rubber pier 3, the rubber pier 3 is deformed, and the buffer material 5 is ensured to fail so that part of external impact force can be absorbed and relieved through the rubber pier 3.
