Description

Technical Field

[0001] The invention relates to the technical field of automobile anti-collision beams, in particular to an anti-collision beam of an automobile rear bumper. Background Art

[0002] The anti-collision beam of a car is set at the front or rear end of the car body, and is mainly used to absorb the collision energy generated during a collision. When a collision occurs, the anti-collision beam is the first line of defense for the passive safety of the car, and plays a very important role in protecting the safety of the vehicle and passengers. The anti-collision beam is an important safety component in the car. It can reduce the transmission of collision energy to the interior of the car when the car collides, so as to protect the occupants in the car and other parts of the car body. The anti-collision beams currently used on the market are mostly simple Japanese-shaped cross-section structures, and a plastic bumper is directly installed at the rear. After a traffic accident collision occurs, the Japanese-shaped anti-collision beams commonly used in practice undergo limited deformation and can only provide a certain degree of protection for the rear of the car. In the case of high-intensity collisions, they are prone to direct fracture, and the buffering effect is not good. Basically, the impact force from the rear is completely transmitted directly to the main structure of the car body through the anti-collision beam. Therefore, in the case of high-intensity collisions, the anti-collision performance of the anti-collision beam is not ideal. Summary of the Invention

[0003] (1) Technical problems solved

[0004] In view of the deficiencies in the prior art, the present invention provides an anti-collision beam for a rear bumper of an automobile, which solves the problem that the anti-collision beams currently used on the market are mostly simple Japanese-shaped cross-section structures, and a plastic bumper is directly installed at the rear. After a traffic accident collision occurs, the Japanese-shaped anti-collision beams commonly used in practice undergo limited deformation and can only provide a certain shielding effect at the rear of the vehicle. In the event of a high-intensity collision, they are prone to direct breakage and have a poor buffering effect. Basically, the impact force from the rear is completely transmitted directly to the main structure of the vehicle body through the anti-collision beam.

The middle part of the protective sleeve pad 13 is provided with a through groove. The right side of the horizontal push anti-collision steel plate 5 is fixedly connected with two pressure-resistant blocks 14. The two pressure-resistant blocks 14 are symmetrically distributed in the upper and lower parts with the middle part of the horizontal push anti-collision steel plate 5.

One end of the inner pull steel block 21 is inserted into the interior of the clamping block 20, and the inner pull steel block 21 is fixedly connected to the top of the rectangular steel push plate 16 and the bottom of the rectangular steel sleeve plate 15. The end of the steel block 21 is fixedly connected with an anti-slip steel block 22, and the interior of the anti-slip steel block 22 is clamped in the interior of the clamping block 20. The left side of the clamping block 20 is fixedly welded with a limited stop block 23. Through the arrangement of the clamping block 20 and the inner pull-out steel block 21, the connection stability strength between the clamping block 20 and the horizontal push anti-collision steel plate 5 is strengthened. The surface of the limit stop block 23 is fixedly connected to the surface of the horizontal push anti-collision steel plate 5. Through the arrangement of the limit stop block 23, the clamping block 20 is provided with a stable resistance effect. A prestressed arc steel plate assembly 24 is provided on the right side of the protective sleeve pad 13. The prestressed arc steel plate assembly 24 includes three arc steel plates. The outer arc surfaces of the three arc steel plates are fixedly stacked on each other in sequence. The two ends of the prestressed arc steel plate assembly 24 are divided into The two clamping blocks 20 are respectively pressed in the grooves of the two clamping blocks 20. The setting of the two clamping blocks 20 plays the effect of prestressing the prestressed curved steel plate set 24. The left side of the prestressed curved steel plate set 24 is fixedly connected with a protective soft plate 25. The setting of the protective soft plate 25 plays the effect of absorbing and slowing down the energy generated by the impact. The left side of the prestressed curved steel plate set 24 is fixedly connected with two resisting inclined blocks 26. The inclined surfaces of the two pushing inclined blocks 17 are in sliding contact with the inclined surfaces of the two resisting inclined blocks 26 respectively. Through the setting of the resisting inclined blocks 26 and the pushing inclined blocks 17, when the prestressed curved steel plate set 24 is subjected to a strong impact, the prestressed curved steel plate set 24 is deformed to the left side compared with the initial state.The inclined displacement of the two resisting inclined blocks 26 and the two pushing inclined blocks 17 drives the rectangular steel push plate 16 to insert into the rectangular steel sleeve plate 15 for telescopic displacement, converting part of its lateral impact force into vertical force, which is buffered by the high-strength compression spring 18. A plastic bumper 27 is sheathed on the right side of the surface of the prestressed curved steel plate assembly 24. The top and bottom of the plastic bumper 27 are respectively clamped on the grooves of the two clamping blocks 20. A plurality of compression thrust springs 28 are fixedly installed inside the plastic bumper 27. The other end of the compression thrust spring 28 is fixedly connected to the right side of the prestressed curved steel plate assembly 24. An air compression spring 29 is fixedly connected to the middle part of the right side of the prestressed curved steel plate assembly 24. The right side of the air compression spring 29 is fixedly connected to the inner wall of the plastic bumper 27. The arrangement of the compression thrust spring 28 and the air compression spring 29 plays a role in utilizing the buffering displacement of the plastic bumper 27 to the left, thereby achieving the effect of preventing collision and protecting the plastic bumper 27 during low-speed collisions.

[0027] When in use, after being hit by a low-speed collision, the plastic bumper 27 is buffered and displaced to the left and right by the plastic bumper 27, and the elastic force of the compression thrust spring 28 and the air compression spring 29 is used to drive the plastic bumper 27 to move back to prevent collision, so that the plastic bumper 27 has a certain buffer space, and the plastic bumper 27 is protected and prevented from collision. When being hit by a high-intensity impact, the plastic bumper 27 is first buffered and displaced in cooperation with the compression thrust spring 28 and the air compression spring 29 to consume the force of the impact, and then the prestressed arc steel plate set 24 is prestressed and fixed by the upper and lower clamping blocks 20, so that the prestressed arc steel plate set 24 has prestressed anti-collision energy in the opposite direction of the impact force, which is offset again by the force of the impact. The wear-resistant and anti-collision sandbags 3 and sand 4 arranged between the plates 5 utilize a large amount of sand 4 to displace inside the wear-resistant and anti-collision sandbags 3 and splash outward to absorb its impact energy again, and when the anti-collision steel plate 5 is pushed horizontally and displaced to the left for buffering after being hit, it drives the solid compressed steel block 9 to telescopically displace inside the high-strength steel sleeve block 7, so that they squeeze the first buffer high-density plastic block 8 and the second buffer high-density plastic block 11 against each other, and utilize the materials of the first buffer high-density plastic block 8 and the second buffer high-density plastic block 11 to absorb their impact force, greatly reducing the intensity of the vehicle collision, effectively protecting its main frame, and then achieving the purpose of protecting its passengers. At the same time, the contents not described in detail in this specification belong to the existing technology well known to professional and technical personnel in this field.

[0028] In summary, the anti-collision beam of the rear bumper of the car is provided with a protective steel plate 2, as well as wear-resistant anti-collision sandbags 3, sand 4, horizontal push anti-collision steel plate 5, pressure-resistant steel plate 6, high-strength steel sleeve block 7, first buffer high-density plastic block 8, solid pressure steel block 9, installation docking plate 10, second buffer high-density plastic block 11, uniform force steel plate 12, protective sleeve pad 13, pressure-resistant block 14, rectangular steel sleeve plate 15, rectangular steel push plate 16, pushing oblique block 17, high-strength compression spring 18, clamping block 20, inner pull-out steel block 21, anti-slip steel block 22, limit block 23, prestressed arc steel plate set 24, protective soft plate 25, push oblique block 26, plastic bumper 27, compression thrust spring 28 and air compression spring 29. The plastic bumper 27 is used in conjunction with the elastic force of the compression thrust spring 28 and the air compression spring 29 to enable the car to move at low speed. Under the collision, the plastic bumper 27 is hit by the left and right buffering displacement to prevent it from collision, and the prestressed curved steel plate set 24 is prestressed and squeezed and fixed by the upper and lower clamping blocks 20, so that the prestressed curved steel plate set 24 has prestressed anti-collision energy in the opposite direction of the impact force under high-intensity collision, and cooperates with the sand 4 contained in the wear-resistant anti-collision sandbag 3 to absorb the collision energy, and effectively buffers the impact force. At the same time, after the horizontal push anti-collision steel plate 5 is hit, it is displaced by horizontal buffering, driving the solid compressed steel block 9 to expand and contract inside the high-strength steel sleeve block 7, so that they squeeze the first buffer high-density plastic block 8 and the second buffer high-density plastic block 11 against each other, and use the materials of the first buffer high-density plastic block 8 and the second buffer high-density plastic block 11 to absorb the impact force, thereby effectively achieving the effect of protecting its passengers.
