Description

Technical Field

[0001] The utility model relates to the technical field of buffering and energy absorption, in particular to an anti-collision guard plate with a honeycomb structure. Background Art

[0002] In the military, civil, transportation, industrial and other fields, automobiles, aerospace, ships, engineering machinery and equipment are susceptible to vibration and shock. Vibration and collision shock can shorten the life of equipment, damage it, and even threaten human life in serious cases. The impact of collision shocks in situations such as car collisions, ship collisions, aircraft take-offs and landings, elevator falls, and impact ground pressure is short in duration, strong in impact force, and large in degree of damage, but it is unavoidable, and energy-absorbing buffer devices are an effective way to alleviate impact damage. When impacted, the energy-absorbing buffer device absorbs the energy generated by the impact through plastic deformation or destruction of the internal device structure, while weakening the impact force and reducing the impact speed. However, the energy absorption effect of the existing energy-absorbing buffer devices is not obvious, the energy absorption efficiency is low, and the energy absorption path is single.

[0006] Furthermore, through holes are opened on the crests and troughs of the wave bands, and the adjacent wave bands are symmetrically arranged according to the flat band axis between the wave bands.

[0007] Furthermore, a through hole is provided on the non-contact portion of the flat belt and the wave belt.

[0008] Furthermore, the amount of the buffer fluid added does not exceed 50% of the volume of the housing.

[0009] Furthermore, the buffer fluid is a non-Newtonian fluid.

[0010] Furthermore, the honeycomb structure anti-collision guard plate is a modular structure, and the edges of adjacent honeycomb structure anti-collision guard plates are welded and fixed into one body after being fitted together.

[0017] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0018] A honeycomb anti-collision guard plate includes an outer shell 1 and a honeycomb structure located within the outer shell 1. The edge of the honeycomb structure is fixed on the inner wall of the outer shell 1. The gaps in the honeycomb structure are filled with a buffer fluid 2, and the buffer fluid 2 is a non-Newtonian fluid. The aforementioned honeycomb structure is composed of flat strips 3 and wave strips 4 stacked in sequence, and the wave strips 4 include crests and troughs.

[0019] In some embodiments, such as Figure 1 and Figure 3As shown, in the honeycomb structure, the wave bands 4 located on the left and right sides of the flat band 3 are axially symmetrical with respect to the flat band 3 located in the middle, the crests and troughs of the wave bands 4 are welded to the flat band 3, and a through hole 5 penetrating the thickness of the flat band 3 is opened on the portion of the flat band 3 that is not in contact with the wave band 4, so that the left and right sides of the flat band 3 are connected to the space surrounded by the wave band 4, and the aforementioned connected space is filled with a buffer liquid for absorbing the kinetic energy generated by the collision impact to play an anti-collision function.

[0020] In other embodiments, such as Figure 2 and Figure 3 As shown, in the honeycomb structure, the wave patterns of the wave bands 4 located on the left and right sides of the flat belt 3 are completely consistent, and the crests and troughs of the wave bands 4 located on the left and right sides of the flat belt 3 are welded to the flat belt 3, and at least one through hole 5 is opened on the wave band 4, so that the buffer liquid can move in the space between the two adjacent flat belts 3 to absorb the kinetic energy generated by the collision impact, so as to play an anti-collision function.

[0021] It is worth noting that in the present invention, the volume of the buffer fluid 2 filled in the honeycomb structure does not exceed 50% of the volume of the shell 1, that is, the buffer fluid 2 can flow to a certain extent in the space inside the shell 1 to complete the consumption and absorption of kinetic energy.

[0022] In the present invention, the honeycomb structure anti-collision guard plate has a modular structure. The edges of adjacent honeycomb structure anti-collision guard plates are welded and fixed as a whole for application. In order to facilitate the edge fitting of the honeycomb structure anti-collision guard plates, they can be set to hexagonal, square or parallelogram structures to reduce the difficulty of laying the honeycomb structure anti-collision guard plates.

[0023] By applying a honeycomb carrier to form an anti-collision guard plate, its weight is much smaller than that of a conventional anti-collision guard plate. Due to the application of the honeycomb carrier located in the outer shell 1, it can play a good buffering role when encountering a collision, and the buffer fluid 2 filled therein can further absorb the impact and reduce shock.

[0024] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
