Technical Field

[0001] This utility model belongs to the field of bumper technology, specifically a bumper protective buffer device. Background Technology

[0002] Car bumpers are safety devices that absorb and mitigate external impacts and protect the front and rear of the vehicle. With the continuous improvement of the national economic level and the increasing number of cars, traffic conditions are becoming more and more complex. Therefore, in traffic accidents, the quality of the bumper's protective performance directly affects whether the occupants can be guaranteed personal safety in the collision. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a bumper protection buffer device that buffers external impacts in traffic accidents, improves protective performance, and protects the personal safety of drivers and passengers.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a bumper protection buffer device, including a bumper body and an anti-collision beam body disposed behind the bumper body. A fixing component is disposed on the rear end face of the bumper body, and two rollers are rotatably disposed on the rear end of the fixing component. A guide rail is symmetrically disposed on the front end face of the anti-collision beam body, and a buffer slider is slidably disposed on the guide rail. A driving inclined surface is disposed on the side of the buffer slider near the rollers, and the driving inclined surface abuts against the outer surface of the rollers. A support end is disposed on the side of the guide rail away from the driving inclined surface. A sliding rod is disposed on the side of the buffer slider away from the driving inclined surface. One side of the sliding rod passes through the support end and can slide horizontally on the support end. A buffer spring is disposed on the sliding rod between the support end and the buffer slider. Anti-resistance support rods are symmetrically disposed between the bumper body and the anti-collision beam.

[0005] Furthermore, the fixing component includes a mounting plate disposed on the rear end face of the bumper body, connecting seats symmetrically spaced on both sides of the rear end face of the mounting plate, and the rollers rotatably mounted on the connecting seats.

[0006] Furthermore, a limit block is provided on the slide rod on one side of the support end, and one end of the buffer spring abuts against the side wall of the support end, while the other end abuts against the side wall of the buffer slider.

[0007] Furthermore, the resistance support rod has a hollow internal structure and a rectangular cross-section. A rectangular intermediate reinforcing member is provided at the center of the resistance support rod. An inclined reinforcing member is provided at the corner of the outer wall of the intermediate reinforcing member, which is connected to the corner of the inner wall of the resistance support rod. A connecting reinforcing member is provided at the middle of the peripheral wall of the intermediate reinforcing member, which is connected to the inner wall of the resistance support rod.

[0008] Furthermore, the intermediate reinforcing member is provided with X-reinforcing members arranged in a cross pattern. The two ends of the X-reinforcing members are connected to the four corners of the inner wall of the intermediate reinforcing member, and the X-reinforcing members correspond to the inclined reinforcing members.

[0009] The beneficial effects of this utility model are:

[0010] This invention utilizes a combination of a fixed assembly, rollers, guide rails, buffer sliders, a driving ramp, a support end, a sliding rod, a buffer spring, and a resisting support rod. When the bumper body receives an external impact, the resisting support rod first provides support to resist the impact. As it deforms and collapses backward, it drives the fixed assembly and rollers towards the main body of the anti-collision beam. The rollers roll along the driving ramp, which in turn drives the two buffer sliders to move horizontally along the guide rail towards the support end. This causes the sliding rod to move horizontally on the support end, and the buffer sliders then compress the buffer spring to further mitigate the impact force. This effectively buffers the external impact, improves the bumper's protective performance, and effectively protects the personal safety of drivers and passengers in traffic accidents.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Reference Figure 1-3As shown, the bumper protection buffer device includes a bumper body 1 and a crash beam body 2 located behind the bumper body 1. A fixing component 3 is provided on the rear end face of the bumper body 1. Two rollers 4 are rotatably mounted on the rear end of the fixing component 3. The fixing component 3 includes a mounting plate 301 located on the rear end face of the bumper body 1 and connecting seats 302 symmetrically spaced on both sides of the rear end face of the mounting plate 301. The rollers 4 are rotatably mounted on the connecting seats 302. A gap is left between the outer surfaces of the two rollers 4. The fixing component 3 is located in the middle of the bumper body 1. A guide rail 5 is symmetrically provided on the front end face of the crash beam body 2. The guide rail 5 passes through... The buffer slider 6 is fixed to the front end of the anti-collision beam body 2 by bolts. A buffer slider 6 is slidably arranged on the guide rail 5. A driving slope 601 is provided on the side of the buffer slider 6 near the roller 4. The driving slope 601 abuts against the outer surface of the roller 4. The distance between the driving slopes 601 of the two buffer sliders 6 is a tapered structure with the inner diameter gradually decreasing from the front end to the rear end of the buffer slider 6. When the bumper body 1 collapses backward, it drives the fixing component 3 and the roller 4 to move backward, and then drives the roller 4 to roll on the driving slope 601, which in turn drives the buffer slider 6, causing the two buffer sliders 6 to move horizontally to both sides along the guide rail 5 and move away from each other.

[0018] A support end 7 is provided on the side of the guide rail 5 away from the drive ramp 601. When the bumper body 1 collapses backward and approaches the anti-collision beam body 2, the support end 7 also provides support and resistance to the collapsed bumper body 1 to further alleviate the impact force. A slide rod 8 is provided on the side of the buffer slider 6 away from the drive ramp 601. One side of the slide rod 8 passes through the support end 7 and can slide horizontally on the support end 7. A buffer spring 9 is provided on the slide rod 8 between the support end 7 and the buffer slider 6. A limit block 801 is provided on the slide rod 8 on one side of the support end 7. One end of the buffer spring 9 abuts against the side wall of the support end 7, and the other end abuts against the side wall of the buffer slider 6. When the buffer slider 6 moves horizontally along the guide rail 5, the buffer slider 6 moves closer to the support end 7, the slide rod 8 slides on the support end 7, and the buffer slider 6 squeezes the buffer spring 9 to relieve the impact force. The limit block 801 prevents the slide rod 8 from separating from the support end 7.

[0019] A resisting support rod 10 is symmetrically arranged between the bumper body 1 and the anti-collision beam body 2. The resisting support rod 10 is fixedly connected to the bumper body 1 and the anti-collision beam body 2 by bolts. When the bumper body receives an external impact, the resisting support rod first supports and resists the external impact. The resisting support rod 10 has a hollow internal structure and a rectangular cross-section. A rectangular intermediate reinforcing member 11 is provided at the center of the resisting support rod 10. An inclined reinforcing member 12 is provided at the corner of the outer wall of the intermediate reinforcing member 11, which connects to the corner of the inner wall of the resisting support rod 10. A connecting reinforcing member 13 is provided at the middle of the perimeter of the intermediate reinforcing member 11, which connects to the inner wall of the resisting support rod 10. The part is provided with X-reinforcing members 14 arranged in a cross pattern. The two ends of the X-reinforcing members 14 are connected to the four corners of the inner wall of the intermediate reinforcing member 11. The X-reinforcing members 14 correspond to the inclined reinforcing members 12. The intermediate reinforcing members 11, inclined reinforcing members 12, connecting reinforcing members 13, and X-reinforcing members 14 increase the structural strength and rigidity of the support rod 10, making it less prone to deformation and damage under impact, thus improving its protective effect. When the support rod 10 is subjected to force, the external force is dispersed and transmitted through the inclined reinforcing members 12 and connecting reinforcing members 13 to the intermediate reinforcing members 11 and X-reinforcing members 14 for resistance. This allows the external force to be distributed to various places, making it less likely to be damaged or deformed due to the concentration of force in one place.
