Description

Technical Field

[0001] The utility model relates to the technical field of shock absorption and noise reduction, in particular to a pad type shock absorber. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the invention recited in the claims. No admission is made that the description herein is prior art by virtue of its inclusion in this section.

[0003] Currently, external air cushion shock absorbers primarily achieve shock absorption by filling the housing with gas at a predetermined pressure. The housing is then expanded by the high-pressure air, achieving the desired cushioning effect. A Chinese utility model patent (patent number 00262402.8) provides an external air cushion shock absorber. However, this approach lacks protection against lateral stress and vibration in the water pump inlet and outlet pipes. Furthermore, the integrated structure makes it impossible to replace the airbag if a single component fails. Failure of a single component requires replacement of the entire shock absorber. The reasons are as follows:

[0004] 1. The elastic bearing is only provided at the top of the chamber, and the shock absorber mainly exhibits longitudinal shock absorption capability, while the lateral shock absorption capability is relatively weak.

[0005] 2. The outer shell adopts an integrated structure and cannot be replaced.

[0006] Therefore, the existing technology needs to be further improved. Utility Model Content

[0007] The purpose of this utility model is to solve the problems of poor lateral stress and vibration protection of the water inlet and outlet pipes of the water pump and the problem that the integrated structure cannot replace the airbag failure. A pad-type shock absorber is proposed to reduce the longitudinal and lateral vibration of the water pump in the data center, and the device can be easily replaced after decompression.

[0008] In order to achieve the above-mentioned purpose, the present utility model adopts the following technical solutions.

[0009] First, on the one hand, the utility model provides a pad-type shock absorber, comprising a base, a supporting platform and a hydraulic spring, wherein the two ends of the hydraulic spring are respectively connected to the base and the supporting platform, and are not perpendicular to the base and / or the supporting platform, and the base comprises a buffer portion and a bottom support, and the buffer portion accommodates an inflatable spherical air cushion, and the spherical air cushion is in contact with the supporting platform in an inflated state, and a gap is provided between the upper surface of the buffer portion and the supporting platform.

[0010] In some embodiments, the hydraulic spring is connected to the supporting platform via a universal wheel.

[0011] Furthermore, one end of the hydraulic spring connected to the bottom seat is inclined in a direction away from the spherical air cushion.

[0012] Furthermore, the hydraulic springs are arranged in an array around the buffer portion.

[0013] Furthermore, the hydraulic spring is connected to the bottom seat via screws.

[0014] Furthermore, the buffer portion is provided with an arc-shaped groove and an inflation hole communicated with the spherical air cushion, and the spherical air cushion fits with the arc-shaped groove in an inflated state.

[0015] Furthermore, the spherical air cushion includes an outer rubber layer, a reinforcing cloth layer and an inner rubber layer which are arranged in sequence.

[0016] Furthermore, a shock-absorbing plate is provided above the base.

[0017] Furthermore, the buffer portion is provided with an inflation valve, and the inflation valve passes through the buffer portion through an inflation hole, so that external air can enter the spherical air cushion through the inflation valve.

[0018] Furthermore, a shock-absorbing pad is provided above the supporting platform, and the shock-absorbing pad is provided with a screw hole for cooperating with a water pump fixing screw to fix the water pump.

[0019] The utility model has the following beneficial effects:

[0035] Example 1

[0036] First, this embodiment provides a cushion type shock absorber, the overall structure of which is as follows: Figure 1 As shown, it includes a base, a supporting platform 13 and a hydraulic spring 9, the two ends of the hydraulic spring 9 are respectively connected to the base and the supporting platform 13, and are not perpendicular to the base and / or the supporting platform 13. The base includes a buffer portion 6 and a bottom support 7. The buffer portion 6 accommodates an inflatable spherical air cushion 14. The spherical air cushion 14 fits with the supporting platform 13 in the inflated state. A gap is provided between the upper surface of the buffer portion 6 and the supporting platform 13. Figure 2 .

[0037] Among them, the supporting platform 13 is made of metal material in the shape of a flat plate, and the bottom is fixed to the universal wheel 10 of the hydraulic spring 9 through a connector, and the top surface is provided with screw holes for fixing the supporting water pump. A shock-absorbing pad 11 is provided on the top of the supporting platform 13, and the shock-absorbing pad 11 is provided with screw holes for cooperating with the water pump fixing screws 12 to fix the water pump. The base is made of metal material with a semicircular buffer part 6 to protect the air cushion, and has air holes. There are several holes near the periphery for fixing screws 8. A shock-absorbing plate 5 is provided on the top of the base. The spherical air cushion 14 adopts a three-layer facility: an outer layer of rubber 1, a reinforced cloth layer 2 in the middle, and an inner layer of rubber 3 to form a single air cushion spherical structure. The air cushion fits into the semicircular groove of the base, and the high-pressure air expands the flange to achieve the purpose of buffering and shock absorption. The buffer part 6 is provided with an inflation valve 4, which is located on the side of the spherical air cushion 14 and is inflated through the inflation nozzle on the side. The inflation valve 4 passes through the buffer portion 6, so that outside air can enter the spherical air cushion 14 through the inflation valve 4. The hydraulic spring 9 is connected to the supporting platform 13 through the universal wheel 10. The hydraulic spring 9 is made of metal material. The bottom of the hydraulic spring 9 is provided with a screw 8, which is fixed to the base by the screw 8. The hydraulic spring 9 is fixed to the supporting platform 13 through the universal wheel 10. Figure 2 As shown, the hydraulic springs 9 are arranged in an array around the buffer portion 6, and the end of the hydraulic spring 9 connected to the bottom support 7 is inclined away from the spherical air cushion 14. When the water pump is subjected to lateral vibration, the expansion and contraction of the hydraulic spring 9 can achieve the purpose of lateral buffering and shock absorption. The detailed structure of the hydraulic spring 9 is shown in FIG. Figure 3 shown.

[0038] When gas at a predetermined pressure is injected into spherical air cushion 14 through inflation valve 4, it deforms under the action of the high-pressure air. The top of spherical air cushion 14 bulges upward to absorb longitudinal shock, while hydraulic spring 9 and universal wheel 10 absorb lateral shock. This design allows the air cushion shock absorber to absorb both longitudinal and lateral impact forces. The non-integrated structure also facilitates maintenance and replacement.

[0039] It can be seen that the utility model can effectively reduce lateral vibration under the support of the hydraulic spring 9 and the universal wheel 10. The elastic bearing of the outer cover type air cushion shock absorber is only set at the top of the chamber, and the lateral shock absorption capacity is relatively weak. In addition, the utility model is non-integrated in the air cushion, and it can be easily improved after decompression. The outer cover type air cushion shock absorber shell adopts an integrated structure and cannot be replaced. The key point of the design of the air cushion shock absorber of the utility model lies in its unique structural design, especially the semicircular fixing groove of the air cushion outer frame to protect the air cushion better from longitudinal pressure. The air cushion adopts a three-layer design (outer layer, middle layer, inner layer) to improve air tightness and elasticity. The liquid level spring universal wheel 10 supports and enhances the lateral shock absorption effect. Specifically, it is manifested as follows:

[0040] Compared with the technology in the utility model and patent CN00262402.8, the differences of this design are mainly reflected in the following aspects: First, in terms of structural design, this design adopts a spherical air cushion 14 outer frame semicircular fixing groove to protect the air cushion to better support longitudinal pressure. The air cushion adopts a three-layer design (outer layer, middle layer, inner layer) to improve air tightness and elasticity instead of direct nesting in the existing technology, thereby improving air tightness and assembly convenience; secondly, under the protection of the semicircular fixing groove of the air cushion outer frame, the structural strength of the air cushion is enhanced and the shock absorption performance is optimized; finally, in terms of working principle, this design is supported by hydraulic springs 9 and universal wheels 10 to achieve comprehensive shock absorption in the longitudinal and transverse directions, overcoming the limitation of the single shock absorption effect in the existing technology.

[0041] In summary, the utility model has the following advantages:

[0042] 1. The air cushion of the utility model is non-integrated and can be easily replaced after decompression. Secondly, the air cushion can be better protected and supported and shock-absorbed by longitudinal pressure in the semicircular fixing groove of the outer frame. The outer cover air cushion shock absorber shell adopts an integrated structure and cannot be replaced.

[0043] 2. The utility model realizes vertical and horizontal shock absorption through the spring liquid level universal support, overcoming the limitation of the single shock absorption effect in the existing technology. The elastic support of the outer cover type air cushion shock absorber is only set at the top of the chamber, and the horizontal shock absorption ability is relatively weak.

[0044] Finally, it should be pointed out that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents.
