Detailed Implementation

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] An impact-resistant energy-absorbing device includes: an elastic energy-absorbing structure 1, a support base 2, a rotating shaft 3, and a loading pad 4; wherein the elastic energy-absorbing structure 1 is a combined sandwich structure including an upper panel 1.1, a lower panel 1.2, and an elastic corrugated sandwich panel 1.3.

[0030] Example 1:

[0031] like Figures 1 to 6 As shown, the elastic energy absorption device consists of an upper panel 1.1, a lower panel 1.2, and an elastic corrugated sandwich panel 1.3, forming a combined sandwich structure. It is an energy-absorbing and vibration-resistant structure with high overall rigidity, good elasticity, and strong load-bearing capacity.

[0032] The upper panel 1.1 and the lower panel 1.2 form an envelope structure, serving as the main load-bearing component. The ply thickness, 0°, ply ratio, and spanwise stiffness are designed according to load-bearing requirements.

[0033] The elastic corrugated sandwich panel 1.3 supports the upper panel 1.1 and the lower panel 1.2, improving the overall rigidity of the composite sandwich structure. It has good elasticity and strong load-bearing capacity.

[0034] The elastic corrugated sandwich panel 1.3 can adopt a damped oscillating waveform and is expandable and deformable. When subjected to external impact or vibration, it absorbs the impact force by contracting and expanding, thereby achieving a buffering effect.

[0035] The 1.3 flexible corrugated sandwich panel can be designed with different thicknesses, layup directions, and corrugation numbers, and the elastic modulus can be adjusted to suit different vibration frequencies and load-bearing capacities.

[0036] Elastic corrugated sandwich panels 1.3 commonly use symmetrical structures, but asymmetrical waveform designs are also possible, allowing the sandwich energy absorption mechanism to exhibit linear or nonlinear elastic characteristics.

[0037] The upper panel 1.1, lower panel 1.2, and elastic corrugated sandwich panel 1.3 can be formed using a heat press process with fiber-reinforced thermosetting composite materials or by heat pressing with fiber-reinforced thermoplastic composite materials. Each component can be mass-produced separately, reducing manufacturing costs.

[0038] The upper panel 1.1, the lower panel 1.2, and the elastic corrugated sandwich panel 1.3 are equipped with a buffer pad between them for absorbing impact and reducing vibration and improving smoothness. The selection of a suitable buffer pad needs to consider factors such as its material, hardness, and installation position. Its main function is to absorb and disperse impact force, reduce the vibration and noise of the energy-absorbing structure.

[0039] The upper panel 1.1, the lower panel 1.2, and the elastic corrugated sandwich panel 1.3 are connected by a rotating shaft 3 at the end of the hanger or clamping device, and are equipped with a buffer pad between them to form an elastic energy-absorbing structure 1.

[0040] The elastic energy-absorbing structure 1 is connected to the support base 2 by a rotating shaft 3, and a loading pad 4 is configured to adjust the buffer pad and match the frequency requirements.

[0041] Working principle: The elastic energy-absorbing structure 1 is connected to the base through the end hanger or clamping device. When subjected to vibration impact load, the elastic energy-absorbing structure 1 converts impact energy into internal energy through structural deformation, achieving the effect of buffering. Each substructure can deform and absorb energy separately, and the overall coordinated deformation is achieved through mutual contact support. In the area of the end hanger or clamping device, the buffer pad is set between the upper panel 1.1, the lower panel 1.2, and the elastic corrugated sandwich panel 1.3. The substructures can be slightly misaligned, the damping of the elastic energy-absorbing structure 1 is increased, and the vibration is attenuated.

[0042] Obviously, the above embodiments are only examples for the sake of clarity, and are not limited to the implementation. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
