Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an energy-absorbing block for automotive roofs. Background Technology

[0002] Automobiles are one of the main means of transportation in our lives today. Cars usually have roofs, which serve a protective function, such as blocking sunlight, rain, and falling objects. However, the energy-absorbing blocks on car roofs are not very effective at absorbing energy during collisions or rollovers, thus failing to reduce the impact force transmitted to the passenger compartment and not adequately protecting passengers' heads. Therefore, we propose using energy-absorbing blocks for car roofs to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An energy-absorbing block for a car roof includes a first plate. First hexagonal tubes are equidistantly arranged on the lower surface of the first plate. First connecting strips are fixed to the top and bottom of each hexagonal tube. A second plate is disposed below the first hexagonal tubes. The first connecting strips at the top and bottom of the first hexagonal tubes are fixedly connected to the lower surface of the first plate and the upper surface of the second plate, respectively. A foam layer is fixed to the lower surface of the second plate. A third plate is fixed to the lower surface of the foam layer. A corrugated plate is fixed to the lower surface of the third plate. A fourth plate is fixed to the lower surface of the corrugated plate.

[0008] Furthermore, a second regular hexagonal tube is provided inside the first regular hexagonal tube. A second connecting strip is fixed to the top and bottom of the second regular hexagonal tube. The two second connecting strips are respectively fixedly connected to the inner wall of the top and the inner wall of the bottom of the first regular hexagonal tube. Both the second regular hexagonal tube and the second connecting strip are made of aluminum alloy.

[0009] Furthermore, through holes are provided on all six sides of the first and second regular hexagonal tubes.

[0010] Furthermore, the foam layer is a biomimetic bamboo fiber reinforced composite foam board, and a shape memory polymer skeleton is embedded in the foam layer.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides an energy-absorbing block for automobile roofs, which has the following beneficial effects:

[0014] This invention, by setting up a first regular hexagonal tube and a second regular hexagonal tube, allows the first and second regular hexagonal tubes to collapse and deform to absorb energy when the top of the car is impacted, thus dispersing the initial impact force. By setting up a foam layer and embedding a shape memory polymer skeleton within the foam layer, it will be compressed and deformed when subjected to impact force, thereby further absorbing energy. By setting up a corrugated plate, it will deform and absorb energy when subjected to impact force. Therefore, the overall energy absorption effect is good, and it can better protect the safety of passengers' heads. Attached Figure Description

[0017] 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.

[0018] Example

[0019] like Figure 1As shown, an embodiment of the present invention provides an energy-absorbing block for a car roof, comprising a first plate 1, with first regular hexagonal tubes 2 evenly spaced on the lower surface of the first plate 1, first connecting strips 3 fixed to the top and bottom of the first regular hexagonal tubes 2, a second plate 4 disposed below the first regular hexagonal tubes 2, the first connecting strips 3 at the top and bottom of the first regular hexagonal tubes 2 being fixedly connected to the lower surface of the first plate 1 and the upper surface of the second plate 4 respectively, a foam layer 5 fixed to the lower surface of the second plate 4, a third plate 6 fixed to the lower surface of the foam layer 5, a corrugated plate 7 fixed to the lower surface of the third plate 6, and a fourth plate 8 fixed to the lower surface of the corrugated plate 7; the first regular hexagonal tubes... The interior of body 2 is equipped with a second regular hexagonal tube 9. The top and bottom of the second regular hexagonal tube 9 are fixed with a second connecting strip 10. The two second connecting strips 10 are fixedly connected to the top inner wall and bottom inner wall of the first regular hexagonal tube 2, respectively. When the top of the car is hit, the first regular hexagonal tube 2 and the second regular hexagonal tube 9 will collapse and deform to absorb energy and disperse the initial impact force. By setting a foam layer 5, it will be compressed and deformed when subjected to impact force, thereby further absorbing energy. By setting a corrugated plate 7, it will deform and absorb energy when subjected to impact force. Therefore, three-stage energy absorption is achieved, and the overall energy absorption effect is good, which can better protect the safety of the passenger's head.

[0020] In some embodiments, through holes are provided on all six sides of the first regular hexagonal tube 2 and the second regular hexagonal tube 9, so that the first regular hexagonal tube 2 and the second regular hexagonal tube 9 can better collapse and deform to absorb energy when subjected to impact force.

[0021] In some embodiments, the foam layer 5 is a biomimetic bamboo fiber reinforced composite foam board, because the biomimetic bamboo fiber reinforced composite foam board has excellent energy absorption effect. The biomimetic foam structure imitates the layered design of bamboo joints and absorbs energy through pore collapse and fiber deformation. A shape memory polymer skeleton is embedded in the foam layer 5 to improve the structural strength of the foam layer 5 and further improve the energy absorption effect.

[0022] In some embodiments, the first plate 1, the first regular hexagonal tube 2, the first connecting strip 3, the second plate 4, the third plate 6, the corrugated plate 7, the fourth plate 8, the second regular hexagonal tube 9, and the second connecting strip 10 are all made of aluminum alloy. This is because aluminum alloy has the characteristics of high strength and lightweight, and it can absorb energy through plastic deformation, has good impact resistance, and also has good corrosion resistance, so it is not easy to rust.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
