[0002] Shock absorbers are widely used on various equipment to reduce the vibration and impact generated by the equipment during operation; as an important part of mechanical equipment, the performance improvement and technical improvement of shock absorbers are particularly important. Traditional shock absorbers are mostly made of single materials or simple structures such as springs and rubber, and their shock absorption effect is often limited, the effect is relatively simple, and the adaptability is poor. Summary of the invention

[0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a shock-absorbing seat, the main body of which utilizes an elastomer with a special structure to form multiple contact lip structures, thereby forming shock absorption at multiple positions, which can achieve more comprehensive shock absorption and significantly improve the shock absorption effect.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a shock absorbing seat, comprising:

[0005] An inner body, the inner body comprising an upper seat and a lower seat fixed together;

[0006] An outer shell, wherein the outer shell is nested on the inner shell, and the outer shell does not contact the inner shell to form an accommodation space, and the outer shell can be displaced relative to the inner shell;

[0007] an elastic body, the elastic body being located between the outer body and the inner body, being disposed in the accommodating space, and being respectively fitted with the inner body and the outer body;

[0008] The inner body and the outer body are both provided with conical surfaces, including a first conical surface provided on the upper seat, a second conical surface provided on the lower seat, and a third conical surface provided on the outer body; the first conical surface and the third conical surface have the same inclination direction, and the first conical surface and the second conical surface have opposite inclination directions;

[0009] The elastic body is provided with a lip at a contact position of the corresponding conical surface, and the lip is pressed tightly against the corresponding conical surface.

[0010] Preferably, the lip portion of the elastic body includes a first lip portion and a second lip portion located at the first conical surface, a third lip portion and a fourth lip portion located at the second conical surface, and a fifth lip portion and a sixth lip portion located at the third conical surface;

[0011] Among them, the first lip, second lip, third lip, fourth lip, fifth lip and sixth lip of the elastomer are all convex structures, and the elastomer forms a surface that fits the conical surface between the first lip and the second lip, between the third lip and the fourth lip, and between the fifth lip and the sixth lip.

[0012] Preferably, the elastomer has an arcuate annular surface between the first lip and the sixth lip, and the elastomer has a concave annular surface between the fourth lip and the fifth lip, and a closed space is formed between the concave annular surface and the lower seat to form a first recessed portion.

[0013] Preferably, the elastic body has a concave annular surface between the second lip portion and the third lip portion, and a closed space is formed between the concave annular surface and the upper seat to form a second recessed portion.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] like Figures 1 to 3 As shown, the present invention provides a shock-absorbing seat, which mainly includes an upper seat 11, a lower seat 12, an outer shell 2 and an elastic body 3, wherein the upper seat 11 and the lower seat 12 are combined to form an inner body, and the elastic body 3 is arranged in the accommodation space formed between the inner body and the outer shell 2, and the three form a mutually nested connection mode, when the outer shell 2 and the inner body produce relative displacement, the elastic body 3 can be deformed, thereby achieving shock absorption. In actual installation, the inner body can be used as a fixed part and the outer shell 2 as a floating part according to actual conditions; or the inner body can be used as a floating part and the outer shell 2 as a fixed part.

[0039] Specifically, the elastic body 3 is an integral structure made of rubber, and has a special lip structure. The setting of these lips has a shock-absorbing effect. Conical surfaces that fit these lips are correspondingly provided on the inner body and the outer body 2 to form an action position. When the outer body 2 and the inner body produce relative displacement, effective shock absorption is formed. Specifically:

[0040] Combination Figure 6 As shown, the conical surface includes a first conical surface 111 (arranged on the upper seat 11), a second conical surface 121 (arranged on the lower seat 12) and a third conical surface 21 (arranged on the outer shell 2), wherein the first conical surface 111 and the third conical surface 21 have the same inclination direction, and the first conical surface 111 and the second conical surface 121 have opposite inclination directions;

[0041] Combination Figure 4 and Figure 5 As shown, the lips include a first lip 31 and a second lip 32 located at the first conical surface 111, a third lip 33 and a fourth lip 34 located at the second conical surface 121, and a fifth lip 35 and a sixth lip 36 located at the third conical surface 21; wherein the first lip 31, the second lip 32, the third lip 33, the fourth lip 34, the fifth lip 35 and the sixth lip 36 are all convex structures, and the elastomer 3 forms a surface that fits the conical surface between the first lip 31 and the second lip 32, between the third lip 33 and the fourth lip 34, and between the fifth lip 35 and the sixth lip 36 (the surface is also a conical surface, as shown in FIG. 1 ). Figure 4 (indicated by the bold lines in the figure).

[0042] Combination Figure 3 It can be seen that in the internal axial direction of the shock-absorbing seat, at the positions of the first conical surface 111 and the second conical surface 121 corresponding to the upper seat 11 and the lower seat 12, when the inner body and the outer shell 2 produce relative displacement in the axial direction, the first lip 31 and the second lip 32 form contact with the first conical surface 111, and the third lip 33 and the fourth lip 34 form contact with the second conical surface 121, thereby generating a buffer; in the external axial direction of the shock-absorbing seat, at the position of the third conical surface 21 corresponding to the outer shell 2, when the inner body and the outer shell 2 produce relative displacement in the axial direction, the fifth lip 35 and the sixth lip 36 form contact with the third conical surface 21, thereby generating a buffer; in the radial direction of the shock-absorbing seat, since the elastomer 3 is nested with the inner body and the outer shell 2, the conical surface and the lip are also annular structures, and thus when the inner body and the outer shell 2 produce relative displacement or offset in the radial direction, a buffer can be formed in the same way; finally, through the setting of the lip and the conical surface, the overall structure forms a multi-directional shock-absorbing effect, that is, the shock-absorbing seat has a shock-absorbing effect in the axial direction inside, the axial direction outside, and the radial direction, thereby forming a more all-round shock-absorbing.

[0043] Embodiment 2

[0044] On the basis of the first embodiment, the elastic body 3 has an arc-shaped annular surface (such as Figure 4 As shown, the arcuate annular surface is open so that the inner body and the outer body 2 can have space for relative displacement), the elastic body 3 has an inner concave annular surface between the fourth lip 34 and the fifth lip 35, and a closed space is formed between the inner concave annular surface and the lower seat 12, forming a first concave portion 37; combined Figure 4 As shown, the arrangement of the arcuate annular surface and the first recess 37, on the one hand, forms a gap between the outer body 2 and the inner body without contact, thereby enabling relative displacement; on the other hand, it enables the lip at this position to form a convex structure, thereby improving the buffering effect; in addition, the first recess 37 forms an inner hollow structure, which can further promote the shock absorbing effect during the buffering process.

[0045] Embodiment 3

[0046] like Figure 7 As shown, based on Example 1 or Example 2, the elastomer 3 has a concave annular surface between the second lip 32 and the third lip 33, and a closed space is formed between the concave annular surface and the upper seat 11, forming a second recess 38. The second recess 38 is similar to the first recess 37, forming an inner hollow structure, which can further promote the shock absorption effect during the buffering process.

[0047] Furthermore, a spring 5 is disposed in the second recess 38 , and two ends of the spring 5 are respectively pressed against the second lip 32 and the third lip 33 .

[0048] Considering the setting of the conical surface, the spring 5 is also correspondingly set as a tower spring (the tower spring has a conical shape), and the outer wall of the corresponding upper seat 11 located at the second recess 38 is also set as a conical surface to form a fourth conical surface 112.

[0049] The addition of the spring 5, which interacts with the second lip 32 and the third lip 33, can not only form an additional shock-absorbing layer to enhance the overall shock-absorbing effect, but also promote the restoring ability of the elastomer 3 after being vibrated and reduce the residual deformation of the elastomer 3 after the vibration.

[0050] In addition, by utilizing the different damping characteristics and frequency response ranges of the elastic body 3 and the spring 5, by adjusting the distance between the upper seat 11 and the lower seat 12, it is possible to better adapt to vibrations of different frequencies and provide more comprehensive damping protection; for this purpose, a method for adjusting the distance between the upper seat 11 and the lower seat 12 is provided in this embodiment, which is as follows:

[0051] Combination Figure 3 and Figure 7 As shown, the upper seat 11 is fixed to the lower seat 12 by bolts 4 (due to the vibration environment, the bolts 4 need to be set to prevent loosening when fixed), and a gasket 6 is set between the upper seat 11 and the lower seat 12. When adjustment is required, hard gaskets of different thicknesses can be selected for installation, or the gasket 6 can be set to a soft material for adjustment. In addition, during adjustment, the preload force of the elastic body 3 and the spring 5 can be adjusted, thereby better adapting to vibrations of different frequencies and providing more comprehensive shock absorption protection.

[0052] In addition, it should be noted that when adjusting the distance between the upper seat 11 and the lower seat 12, the adjustment should not be a large distance, so as to avoid the elastomer 3 being squeezed out of excessive deformation by the upper seat 11 and the lower seat 12 before it participates in the deformation, thereby affecting the overall shock absorption; in actual use, the adjustment is slight, because the shock-absorbing seat can be set to different sizes, and therefore cannot give a specific adjustment value, and multiple adjustments can be made during installation to achieve the desired shock absorption effect of the equipment.

[0053] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
