Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution for an automobile bumper with a multi - buffer structure:

[0023] Embodiment 1:

[0024] As Figures 1-3 shown, an automobile bumper with a multi - buffer structure includes a bumper main body 1. Buffer side plates 2 are arranged on both sides of the bumper main body 1. An airbag 3 is arranged on the front of the bumper main body 1. Two reinforcing plates 4 are arranged on the back of the bumper main body 1. Contact plates 5 are arranged inside both buffer side plates 2. Convex plates 6 are arranged on one side of both contact plates 5. Receiving plates 11 are arranged on one side of both convex plates 6. Vertical plates 12 are arranged on one side of both reinforcing plates 4. Arc - shaped members 9 are arranged on one side of both buffer side plates 2. Reinforcing rib plates 10 are fixedly installed on one side of both receiving plates 11, enhancing the firmness between the buffer side plates 2 and the bumper main body 1. A triangle is formed among the vertical plates 12, the reinforcing plates 4 and the inclined plates 13, so that the force applied to the bumper main body 1 can be evenly distributed to each corner and edge, avoiding local stress concentration. The combined use of the airbag 3, the receiving plates 11 and the arc - shaped members 9 can further buffer and absorb the impact force, so that the automobile bumper has a multi - buffer function.

[0025] Embodiment 2:

[0026] On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, one side of both inclined plates 13 is fixedly connected to one side of both reinforcing plates 4 respectively. First fitting frames 14 are fixedly installed on one side of both vertical plates 12. Second fitting frames 15 are fixedly installed on one side of both vertical plates 12. Third fitting frames 16 are fixedly installed on one side of both vertical plates 12. For the automobile bumper with a multi - buffer structure of the present invention, by setting the first fitting frames 14, the second fitting frames 15, the damping rubber balls 8 and the third fitting frames 16, the vertical plates 12 and the inclined plates 13 are fixed through the first fitting frames 14, the second fitting frames 15 and the third fitting frames 16, and the lengths of the three are gradually decreasing in turn. When the three are fixed to the vertical plates 12, they also present a triangular shape, and the triangular structure will not be deformed due to the applied force.

[0027] Working principle: With the rapid progress and development of technology, people's living standards have been continuously improving. Automobiles have become one of the essential means of transportation for people to travel. At the same time, how to improve the safety of automobiles while enjoying the convenience brought by them is also one of the topics of general concern. In order to reduce the damage suffered by automobiles from frontal impacts, automobile front bumpers are added to automobiles. The function of the automobile front bumper is to absorb and slow down the external impact force, playing the role of protecting the safety of the front part of the vehicle body. In the above technology, multiple buffering effects can be achieved, greatly increasing the buffering and shock absorption effect of the automobile bumper, improving the impact resistance performance and use safety of the automobile bumper. The two sides of the automobile bumper are arc-shaped, and the arc-shaped part of the bumper is not effectively supported. During a collision, it may deform due to uneven force, resulting in a decrease in structural strength, and may not be able to effectively disperse the collision energy, causing the impact force to concentrate in a small area and increasing the risk of damage. Therefore, innovation is carried out on this technology. The buffer side plate 2 has a certain arc, which can increase the buffering effect of the bumper. One side of the arc-shaped part 9 abuts against one side of the buffer side plate 2, and the support is realized by using the reinforcing rib plate 10 and the accommodating plate 11, enhancing the support strength of the arc-shaped part 9, and further improving the buffering strength of the buffer side plate 2. Triangles have stability. The support of the two triangular plates 7 on both sides of the convex plate 6 enhances the firmness between the buffer side plate 2 and the bumper main body 1. The vertical plate 12, the reinforcing plate 4, and the inclined plate 13 form a triangle, and the force applied to the bumper main body 1 can be evenly distributed to each corner and side, avoiding local stress concentration. The combined use of the airbag 3, the accommodating plate 11, and the arc-shaped part 9 can further buffer and absorb the impact force, so that the automobile bumper has multiple buffering functions. The vertical plate 12 and the inclined plate 13 are fixed through the first fitting frame 14, the second fitting frame 15, and the third fitting frame 16, and the lengths of the three are successively reduced. When the three are fixed to the vertical plate 12, they also present a triangular shape. The triangular structure will not deform due to the applied force. The damping rubber ball 8 can effectively absorb and disperse the impact force, reducing the damage caused by vibration and impact. Part of the kinetic energy will be converted into heat energy, reducing the reaction force, so as to achieve a more stable buffering effect.
