[0027] The utility model provides a kind of composite damping device with energy consumption mechanism, including base 1 and the object platform 2 above base 1, base 1 is connected with object platform 2 by shock insulation rubber sleeve 3, the top and bottom of shock insulation rubber sleeve 3 are respectively provided with several recesses 301 along the circumferential direction of shock insulation rubber sleeve 3, first spring 4 is provided in each recess 301, the bottom end surface of object platform 2 is fixed with several first limit posts 5, the top end surface of base 1 is fixed with several second limit posts 6, several first limit posts 5 and several second limit posts 6 are respectively inserted in the same side of several recesses 301, and the one end of each limit post is connected with its corresponding first spring 4, the inside of shock insulation rubber sleeve 3 is provided with at least one group of energy dissipation components, and the energy dissipation components include second spring 7, upper pressing block 8, third spring 9 and lower pressing block 10, wherein second spring 7 is installed at the bottom end surface of object platform 2, third spring 9 is installed at the top end surface of base 1, second spring 7 and third spring 9 are arranged in vertical opposition, upper pressing block 8 is fixed at the bottom end of second spring 7, and lower pressing block 10 is fixed at the top end of third spring 9.
[0028] The base 1 is the basis of the entire composite damping device, and bears and transmits external vibrations.
[0029] By setting shock insulation rubber sleeve 3 and first spring 4, preliminary damping is achieved, and part of the vibration energy is absorbed; first limit post 5 and second limit post 6 respectively play a guiding role in the upward and downward displacement direction of object platform 2 and base 1, preventing the object platform 2 or base 1 from moving horizontally away from the shock insulation rubber sleeve 3 due to the elastic effect of first spring 4 when absorbing vibration energy.
[0030] The third spring 9 converts vibration energy into elastic potential energy;
[0031] The second spring 7 assists in completing energy conversion and dissipation;
[0032] The upper pressing block 8 and the lower pressing block 10 convert energy, achieving conversion of kinetic energy to potential energy.
[0033] The shock insulation rubber sleeve 3 is a cylindrical structure, and its cross section can be circular, rectangular or any other polygonal shape. The cross-sectional shape of base 1 and object platform 2 is preferably the same.
[0034] Working principle:
[0035] When vibration is applied to base 1, a portion of the energy is first absorbed by shock insulation rubber sleeve 3 and first spring 4, and the remaining vibration energy is stored by third spring 9, causing lower pressing block 10 to move upward and collide with upper pressing block 8 above it. According to the specific situation of the collision, two different energy conversion modes can be produced:
[0036] In the first case, the upper and lower blocks 8, 10 move upward together, then the upper block 8 compresses the second spring 7 until its kinetic energy is completely converted into potential energy of the second spring 7; as the second spring 7 releases potential energy, the upper block 8 obtains kinetic energy and moves back, colliding with the lower block 10 again;
[0037] In the second case, the upper block 8 moves upward and the lower block 10 moves downward, at this time, the upper block 8 compresses the second spring 7 and the lower block 10 compresses the third spring 9, after the kinetic energy of the second spring 7 and the third spring 9 is converted into potential energy, the upper block 8 starts to move downward and the lower block 10 moves upward, finally the upper block 8 and the lower block 10 meet again and collide.
[0038] This cyclic energy conversion and collision process effectively weakens the energy of the original vibration, thereby protecting the objects carried on the object carrying platform 2 from damage.
[0039] The composite shock absorber of the utility model introduces an energy consumption mechanism, significantly enhances the shock absorption effect of the passive shock absorber, and at the same time retains the advantages of low cost and good environmental adaptability.
[0040] The composite shock absorber of the utility model has a compact structure, is easy to integrate into various transportation or mechanical equipment, is suitable for various application scenarios, and is particularly suitable for occasions with high stability and safety requirements, such as precision instrument or electronic product transportation.
[0041] There is a gap between the upper block 8 and the lower block 10. In this way, the upper block 8 and the lower block 10 have sufficient movement allowance, thereby increasing the kinetic energy at the time of collision and further increasing the energy consumption.
[0042] The second spring 7 is fixed to the bottom end face of the object carrying platform 2 through the upper mounting seat 11, and the third spring 9 is fixed to the top end face of the base 1 through the lower mounting seat 12. In this way, by arranging the upper mounting seat 11 and the lower mounting seat 12, the second spring 7 and the third spring 9 are facilitated to be mounted and fixed on the corresponding object carrying platform 2 and base 1.
[0043] The first guide column 13 is fixed to the bottom of the upper mounting seat 11, the second guide column 14 is fixed to the upper block 8, and the two ends of the second spring 7 are respectively sleeved on the first guide column 13 and the second guide column 14. In this way, by arranging the first guide column 13 and the second guide column 14, the second spring 7 is guided to prevent lateral displacement of the second spring 7 during shock absorption and energy consumption, thereby ensuring the shock absorption effect.
[0044] The third guide column 15 is fixed on the top of the lower mounting base 12, the fourth guide column 16 is fixed below the lower pressing block 10, and the two ends of the third spring 9 are sleeved on the third guide column 15 and the fourth guide column 16 respectively. Through the third guide column 15 and the fourth guide column 16, the third spring 9 is guided, so that the transverse displacement of the third spring 9 in the shock energy dissipation process is prevented, and the shock effect is ensured.
[0045] The upper pressing block 8 and the lower pressing block 10 are made of metal. Through the upper pressing block 8 and the lower pressing block 10 made of metal, the mass is larger and the energy consumption is faster.
[0046] The base 1 comprises a bottom plate 101 and a plurality of supporting legs 102 evenly arranged below the bottom plate 101, and the third spring 9 is installed on the bottom plate 101. Through the plurality of supporting legs 102, the support of the entire composite shock absorbing device is achieved, and the movement of the device is facilitated.
[0047] The number of the grooves 301 on the top of the shock insulation rubber sleeve 3 is equal to that on the bottom and is arranged one by one.
[0048] The number of the grooves 301 on the top of the shock insulation rubber sleeve 3 is four.
[0049] The shock insulation rubber sleeve 3 is a cylindrical structure.
[0050] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
