Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically an enhanced automotive bumper. Background Technology

[0002] As an important component of the car body, the car bumper mainly plays a role in protecting the car body and absorbing and mitigating external impacts. During the driving process, when a minor collision or scratch occurs, the bumper can effectively reduce the degree of damage to the car body and internal parts.

[0003] However, traditional car bumpers are mostly made of a single plastic material, with a relatively simple structure and limited impact resistance and strength. In the event of a moderately powerful collision, traditional bumpers are prone to cracking and deformation, failing to adequately protect the car body and occupants. Furthermore, the installation method of traditional bumpers is relatively fixed, making it inconvenient to adjust and maintain according to actual needs. Over long-term use, they are also susceptible to aging and damage due to external environmental factors, resulting in a shorter lifespan.

[0004] To address the problems existing in the above-mentioned technologies, there is an urgent need to develop an enhanced car bumper with a reasonable structure, strong anti-collision performance, high strength, easy adjustment and maintenance, and long service life, so as to meet the ever-increasing demands of the automotive industry for bumper performance.

[0005] Therefore, an enhanced car bumper is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an enhanced car bumper. By setting up a reinforcing mechanism, including a U-shaped anti-collision beam, a first guard bar, a second guard bar, and a reinforcing rod, the multiple structures work together to effectively disperse and absorb collision forces, significantly improving the bumper's anti-collision performance. The bumper has excellent anti-collision performance and can better protect the car body and the safety of the occupants in the event of a collision.

[0008] Preferably, the reinforcing mechanism includes a U-shaped anti-collision beam that runs through the main body of the bumper. A first guard bar is welded to the upper surface of the impact end of the anti-collision beam, and a second guard bar is welded above the first guard bar. A reinforcing rod is installed at the welding position of the first guard bar and the second guard bar. The reinforcing rod is arranged in a quarter-circle arc shape, and the end of the reinforcing rod away from the first guard bar and the second guard bar is welded to the crossbar on the anti-collision beam.

[0009] Preferably, the adjustment mechanism includes a crash plate with an arc-shaped structure hinged to the surface of the crash beam. The surface of the crash plate is coated with an explosion-proof armor paint coating.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4As shown, this utility model provides an enhanced car bumper, including a bumper body 1, a reinforcing mechanism 2, an adjusting mechanism 3, and a connecting mechanism 4. The bumper body 1 is connected to the car body via clips, which facilitates the installation and removal of the bumper body 1 and allows for quick replacement when the bumper body 1 is damaged.

[0023] The reinforcing mechanism 2 is located on one side of the bumper body 1, penetrating the bumper body 1, with its anti-collision end located on the outer side of the bumper body 1. The reinforcing mechanism 2 significantly improves the bumper's anti-collision performance and overall strength. The reinforcing mechanism 2 includes a U-shaped anti-collision beam 21 penetrating the bumper body 1. The U-shaped anti-collision beam 21 has good impact resistance and can effectively disperse collision force. A first guard bar 22 is welded to the upper surface of the impact end of the anti-collision beam 21, and a second guard bar 23 is welded above the first guard bar 22. The double guard bar setup further enhances the anti-collision effect of the reinforcing mechanism 2. Furthermore, reinforcing rods 24 are installed at the welding positions of the first guard bar 22 and the second guard bar 23. The reinforcing rods 24 have a quarter-circle arc structure, and the end of the reinforcing rod 24 away from the first guard bar 22 and the second guard bar 23 is welded to a crossbar on the anti-collision beam 21. The reinforcing rods 24 reinforce the welding points of the first guard bar 22 and the second guard bar 23, preventing breakage during a collision.

[0024] The adjustment mechanism 3 is located below the surface of the reinforcing mechanism 2 and is movably connected to the reinforcing mechanism 2. The adjustment mechanism 3 allows for adjustment of the bumper's anti-collision angle and buffering level according to actual conditions. The adjustment mechanism 3 includes an anti-collision plate 31 with an arc-shaped structure hinged to the surface of the anti-collision beam 21. The surface of the anti-collision plate 31 is coated with an explosion-proof armor paint coating, which has excellent impact resistance and scratch resistance, effectively protecting the anti-collision plate 31. Hydraulic mechanisms 32 are hinged to both ends of the crossbar on the anti-collision beam 21. The extended ends of the hydraulic mechanisms 32 are hinged to the inner arc surface of the anti-collision plate 31. The hydraulic mechanisms 32 can adjust the angle of the anti-collision plate 31 by extending and retracting, thereby better coping with collisions from different directions.

[0025] Two connecting mechanisms 4 are provided, respectively fixedly installed at both ends of the reinforcing mechanism 2. The connecting mechanisms 4 are detachably connected to the vehicle body, ensuring a secure connection between the reinforcing mechanism 2 and the vehicle body while facilitating disassembly and maintenance. The connecting mechanism 4 includes a connecting seat 41, connecting holes 42, and a shock-absorbing pad 43. The connecting seat 41 is fixedly connected to the end of the anti-collision beam 21, and has multiple connecting holes 42. The shock-absorbing pad 43 is positioned between the connecting seat 41 and the vehicle body, and has through holes corresponding to the connecting holes 42. The connecting seat 41 is fixedly connected to the vehicle body by connecting bolts passing through the connecting holes 42 and the through holes. The shock-absorbing pad 43 provides cushioning and shock absorption during vehicle operation and in the event of a collision, reducing the impact of vibration on the vehicle body and bumper.

[0026] To enhance the performance of the bumper body 1, it is made of a high-strength composite material, which is a mixture of polypropylene, glass fiber, and an anti-aging agent in a mass ratio of 5:3:0.5. Polypropylene possesses good toughness and chemical corrosion resistance, glass fiber significantly improves the material's strength and rigidity, and the anti-aging agent effectively slows down the aging process, extending the service life of the bumper body 1. Simultaneously, the surface of the bumper body 1 is coated with an explosion-proof armor paint layer, further enhancing its impact resistance, scratch resistance, and anti-aging properties. Furthermore, a vehicle protection plate 11 is fixedly installed on the bottom surface of the bumper body 1. The vehicle protection plate 11 prevents impacts and damage to the bottom surface of the bumper body 1 from stones, debris, and other objects on the ground during vehicle operation.

[0027] Working principle and process:

[0028] Preparation of bumper body 1: Polypropylene, glass fiber, and anti-aging agent are weighed according to a mass ratio of 5:3:0.5. These raw materials are then thoroughly mixed in a mixing device. The mixed material is then fed into an injection molding machine and injection molded according to the preset shape of the bumper body 1 to obtain a blank of the bumper body 1. After the blank cools, its surface is polished and finished. Then, an explosion-proof armor paint coating is sprayed onto the surface of the bumper body 1. After the coating dries, the preparation of the bumper body 1 is complete. Finally, the car protective plate 11 is fixedly installed on the bottom surface of the bumper body 1 using bolts.

[0029] Preparation of reinforcement mechanism 2: Select metal materials of appropriate specifications and make U-shaped anti-collision beam 21 through bending, welding and other processes. Weld the first guard bar 22 to the upper surface of the impact end of the anti-collision beam 21, and weld the second guard bar 23 above the first guard bar 22. Then weld the reinforcing rod 24 at the welding position of the first guard bar 22 and the second guard bar 23. The end of the reinforcing rod 24 away from the first guard bar 22 and the second guard bar 23 is welded to the crossbar on the anti-collision beam 21 to complete the preparation of reinforcement mechanism 2.

[0030] Preparation of Adjustment Mechanism 3: A metal crash plate 31 is made, designed as an arc-shaped structure. An explosion-proof armor paint coating is applied to the surface of the crash plate 31 and allowed to dry. Then, a hydraulic mechanism 32 of suitable specifications is selected, and the crash plate 31 is movably hinged to the surface of the crash beam 21. One end of the hydraulic mechanism 32 is hinged to both ends of the crossbar on the crash beam 21, and the extended end of the hydraulic mechanism 32 is hinged to the inner arc surface of the crash plate 31, thus completing the preparation and installation of the adjustment mechanism 3.

[0031] Preparation of connecting mechanism 4: Select metal material to make connecting seat 41, open multiple connecting holes 42 on connecting seat 41, select elastic material to make shock-absorbing pad 43, open through holes corresponding to connecting holes 42 on shock-absorbing pad 43, fix connecting seat 41 to the end of anti-collision beam 21 to complete the preparation of connecting mechanism 4.

[0032] The prepared reinforcing mechanism 2 is inserted through the bumper body 1, so that the anti-collision end of the reinforcing mechanism 2 is located on the outside of the bumper body 1. The bumper body 1 is connected to the car body by a buckle. The connecting bolts are passed through the connecting hole 42 on the connecting seat 41 and the through hole on the shock absorber 43 to fix the connecting seat 41 to the car body, thereby completing the assembly of the entire reinforced car bumper.

[0033] During use, the angle of the anti-collision plate 31 can be adjusted by controlling the extension and retraction of the hydraulic mechanism 32 according to the actual road conditions and possible collision situations to achieve the best anti-collision effect. Regularly inspect the bumper to check for damage or looseness in the bumper body 1, reinforcing mechanism 2, adjusting mechanism 3, and connecting mechanism 4. If scratches or coating peeling are found on the surface of the bumper body 1, repair or repaint the anti-explosion armor paint coating in a timely manner. If the connecting bolts are found to be loose, tighten them immediately. If the hydraulic mechanism 32 malfunctions, repair or replace it promptly. When a component of the bumper is severely damaged and needs replacement, first remove the connecting bolts on the connecting mechanism 4, separate the reinforcing mechanism 2 from the car body, then remove the bumper body 1 from the car body using clips, and then replace the damaged part. After replacement, reassemble according to the above assembly steps.
