Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive bumper technology, specifically an automotive anti-collision bumper. Background Technology
[0002] Car bumpers are safety devices installed at the front and rear of a vehicle, primarily used to absorb and mitigate external impacts, protecting the front and rear of the vehicle from collision damage.
[0003] Currently, the structure of car bumpers on the market is relatively simple. To further improve the energy absorption effect of the bumper and enhance its protective performance, a buffer structure can be added inside the bumper. Therefore, we propose a car anti-collision bumper to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an automotive anti-collision bumper to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a car anti-collision bumper, including a high-efficiency protective bumper, the high-efficiency protective bumper including a connecting frame, an anti-collision tube frame, side rails, a buffer inner tube, and a honeycomb grid, the connecting frame having anti-collision tube frames nested and installed on its surface, the anti-collision tube frames being hollow tube structures with both ends open, the left and right ends of the anti-collision tube frames having side rails inserted and installed, and the side rails being bolted to the anti-collision tube frames, the anti-collision tube frames having a buffer inner tube nested inside, and the buffer inner tube having a honeycomb grid integrally formed inside.
[0006] Preferably, the bottom surface of the connecting frame is provided with an insert, and the bottom surface of the buffer inner tube is provided with an insert groove, which can be slidably sleeved with the surface of the insert.
[0007] Preferably, the entire anti-collision pipe frame is made of aluminum alloy.
[0008] Preferably, the inner buffer tube and the honeycomb grid are made of polypropylene.
[0009] Preferably, the inner side of the grid opening of the honeycomb grid is filled with a cushioning air bag, which is in the shape of a long column.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This invention features a high-efficiency protective bumper with a nested buffer inner tube inside the anti-collision tube frame. The buffer inner tube contains a honeycomb grid; the hexagonal structure of the honeycomb grid evenly distributes force across the six adjacent faces when subjected to external pressure, reducing localized stress concentration and enhancing overall compressive strength. This allows the buffer inner tube to effectively absorb impact energy, improving the bumper's anti-collision protection capabilities. Furthermore, buffer airbags are filled inside the honeycomb grid. Upon impact, these airbags, through their own deformation and the cushioning effect of the air, disperse the impact force, preventing it from directly acting on the vehicle's surface and further enhancing the bumper's energy absorption effect.

[0017] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.
[0018] Please see Figure 1-4 This utility model provides a car anti-collision bumper, including a high-efficiency protective bumper 1. The high-efficiency protective bumper 1 includes a connecting frame 11, an anti-collision tube frame 12, a side rail 13, a buffer inner tube 14, and a honeycomb grid 15. The anti-collision tube frame 12 is nested and installed on the surface of the connecting frame 11. The anti-collision tube frame 12 is a hollow tube structure with both ends through. The side rail 13 is inserted and installed at both ends of the anti-collision tube frame 12, and the side rail 13 is fixed to the anti-collision tube frame 12 with bolts. The buffer inner tube 14 is nested inside the anti-collision tube frame 12, and the honeycomb grid 15 is integrally set inside the buffer inner tube 14.
[0019] In use, the connecting bracket 11 is installed and connected to the vehicle part to complete the installation of the high-efficiency protective bumper 1. A buffer inner tube 14 is nested inside the anti-collision tube frame 12. The buffer inner tube 14 has a honeycomb grid 15 inside. When subjected to external pressure, the hexagonal structure of the honeycomb grid 15 can evenly distribute the force to the six adjacent faces, reduce local stress concentration, and thus enhance the overall pressure resistance. This allows the buffer inner tube 14 to effectively absorb impact energy and improve the anti-collision protection capability of the high-efficiency protective bumper 1. Furthermore, a buffer air bag 16 is filled inside the honeycomb grid 15. When impacted, the buffer air bag 16 disperses the impact force through its own deformation and the buffering effect of the air, preventing the impact force from acting directly on the vehicle surface, further improving the buffering and energy absorption effect of the high-efficiency protective bumper 1.
[0020] To further explain, the bottom surface of the connecting frame 11 is provided with an insert 12a, and the bottom surface of the buffer inner tube 14 is provided with an insert groove 14a. The insert groove 14a can slide and fit with the surface of the insert 12a. The cooperation between the insert 12a and the insert groove 14a improves the connection stability between the buffer inner tube 14 and the anti-collision tube frame 12, and prevents the buffer inner tube 14 from rolling inside the anti-collision tube frame 12 and causing abnormal noise.
[0021] To further explain, the entire anti-collision tube frame 12 is made of aluminum alloy. Aluminum alloy is lightweight and has a certain degree of elasticity, which allows the anti-collision tube frame 12 to recover its original shape through elastic deformation after a minor collision, making it more durable.
[0022] To further explain, the inner buffer tube 14 and the honeycomb mesh 15 are made of polypropylene. Polypropylene has the advantages of being lightweight and having high toughness, which can effectively control the overall weight of the high-efficiency protective bumper 1. In addition, polypropylene has high impact resistance, which allows the inner buffer tube 14 to effectively absorb energy when subjected to external impact, making it less prone to breakage and damage, and ensuring its service life.
[0023] To further explain, the inner side of the grid opening of the honeycomb grid 15 is filled with a buffer air bag 16. The buffer air bag 16 is long and cylindrical and is filled with natural air. When impacted, the buffer air bag 16 disperses the impact force through its own deformation and the buffering effect of the air, preventing the impact force from acting directly on the car surface, and further improving the buffering and energy absorption effect of the high-efficiency protective bumper 1.
[0024] By removing the side rail 13 on the side of the anti-collision tube frame 12, the buffer inner tube 14 and buffer air bag 16 inside the anti-collision tube frame 12 can be disassembled and replaced, allowing for partial replacement of parts and effectively reducing the usage and maintenance costs of the high-efficiency protective bumper 1.
[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
