Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically a shock absorber. Background Technology

[0002] Vibration damping blocks are used to be installed inside corresponding equipment for vibration damping.

[0003] Existing damping blocks still have the following problems: Traditional damping blocks are generally single pieces or single-piece pads with relatively simple structures. Operators often need to rely on experience or a general understanding of the equipment structure to place the pads, which can easily lead to installation errors. Once an incorrect installation is made, it needs to be disassembled and reinstalled, further increasing time costs. Moreover, when subjected to force, the force acts directly on its entire surface, causing a single damping block or pad to be subjected to a large impact force instantaneously. This can easily lead to excessive local stress and excessive local deformation. Furthermore, its relatively simple structure makes it difficult to disperse impact forces when faced with uneven impacts, which can also affect the service life and damping performance of a single damping block or pad.

[0004] Therefore, there is an urgent need for a shock-absorbing block to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a shock-absorbing block to solve the problems of short service life and low shock absorption performance of a single shock-absorbing block or pad.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a shock-absorbing block, comprising:

[0007] Gaskets are used to support connections and absorb shock.

[0008] The first mounting position includes a first limiting block and a first connecting block. The first limiting block protrudes from the surface of the gasket body, and the first connecting block connects the first limiting block and the gasket body. The area of ​​the gasket body is larger than the area of ​​the first limiting block and the area of ​​the first connecting block.

[0009] As a preferred embodiment of the shock absorber, it further includes a second limiting block and a second connecting block. The second limiting block protrudes from the surface of the gasket body facing the first limiting block, and the second connecting block connects the second limiting block and the gasket body.

[0010] As a preferred embodiment of the shock absorber, the area of ​​the first limiting block is smaller than the area of ​​the second limiting block, which is smaller than the area of ​​the gasket body, in order to adapt to the installation structure and balance the internal stress distribution.

[0011] As a preferred embodiment of the shock absorber block, the first connecting block and the second connecting block are on the same central axis to uniformly transmit the force.

[0012] As a preferred embodiment of the shock absorber, a transition fillet is provided between the first connecting block and the gasket body, between the first connecting block and the first limiting block, between the second connecting block and the gasket body, and between the second connecting block and the second limiting block.

[0013] As a preferred embodiment of the damping block, it further includes an air cavity disposed within the pad body, the air cavity being used to adjust the damping stiffness and reduce the mass of the pad body.

[0014] As a preferred embodiment of the shock absorber, one or more air cavities are provided, which are used to enhance shock absorption while preventing excessive deformation of the gasket body.

[0015] As a preferred embodiment of a shock absorber, the pad body is made of a relatively soft, elastic material for absorbing and storing energy.

[0016] As a preferred embodiment of the shock absorber, both the first and second limiting blocks are made of relatively hard elastic material to transmit and disperse impact force.

[0017] As a preferred embodiment of a shock absorber, the pad body, the first limiting block, and the second limiting block are all provided with chamfered edges, which are used to guide and disperse impact forces.

[0018] The beneficial effects of this utility model are as follows: By setting the first limiting block and the first connecting block, precise positioning with the external mounting structure can be achieved during installation, effectively improving the accuracy of shock absorption. Operators can more easily judge the installation direction and position of the shock absorber, reducing installation time and the probability of errors, and improving installation efficiency. Through the relay transmission of force by the first limiting block and the first connecting block, the force can be transmitted to the gasket body more smoothly, achieving layered transmission and avoiding the problem of excessive local deformation caused by excessive instantaneous force that may occur with traditional gasket bodies. Since the area of ​​the gasket body is larger than the area of ​​the first limiting block, which is larger than the area of ​​the first connecting block, it helps to disperse uneven impact force, thereby ensuring a long service life and high shock absorption performance.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0031] In one embodiment of this utility model, such as Figure 1-5 As shown, a shock absorber block is provided, including a pad body 1 and a first mounting position 2. The pad body 1 is used for support connection and shock absorption; the first mounting position 2 includes a first limiting block 21 and a first connecting block 22. The first limiting block 21 protrudes from the surface of the pad body 1, and the first connecting block 22 connects the first limiting block 21 and the pad body 1. The area of ​​the pad body 1 is larger than the area of ​​the first limiting block 21, which is larger than the area of ​​the first connecting block 22.

[0032] This utility model provides a shock absorber block that, by setting a first limiting block 21 and a first connecting block 22, can precisely cooperate and position with the external mounting structure during installation, effectively improving the accuracy of shock absorption. Operators can more easily determine the installation direction and position of the shock absorber block, reducing installation time and the probability of errors, thus improving installation efficiency. Through the relay transmission of force by the first limiting block 21 and the first connecting block 22, the force can be transmitted to the pad body 1 more smoothly, achieving layered transmission and avoiding the problem of excessive local deformation caused by excessive instantaneous force that may occur with traditional pad bodies 1. The fact that the area of ​​the pad body 1 is larger than the area of ​​the first limiting block 21 is larger than the area of ​​the first connecting block 22 helps to disperse uneven impact forces.

[0033] This type of shock absorber also includes a second limiting block 31 and a second connecting block 32 forming the second mounting position 3. The second limiting block 31 protrudes from the surface of the pad body 1 facing the first limiting block 21, and the second connecting block 32 connects the second limiting block 31 and the pad body 1. This achieves bidirectional positioning, allowing for more precise determination of the shock absorber's position within the equipment during installation. Simultaneously, operators can easily and correctly install the shock absorber into the equipment based on the position and orientation of the limiting blocks, avoiding installation errors. When the shock absorber is subjected to impact forces from above or below, the force can be transmitted to the pad body 1 through the first connecting block 22 and the second connecting block 32, respectively, enabling the pad body 1 to more evenly bear and distribute pressure. Furthermore, when vibration occurs, the force first undergoes initial buffering through the first limiting block 21 and the second limiting block 31, then is elastically transmitted through the first connecting block 22 and the second connecting block 32, and finally, the pad body 1 performs the main energy absorption and damping, thereby achieving a graded vibration damping effect.

[0034] Specifically, the area of ​​the first limiting block 21 is smaller than the area of ​​the second limiting block 31 and the area of ​​the gasket body 1, in order to adapt to the installation structure and balance the internal stress distribution.

[0035] This difference in area size allows operators to visually distinguish the up-down or reverse directions of the damping blocks, thus avoiding installation errors and accurately installing the damping blocks into the corresponding mounting structures, improving installation efficiency and accuracy. Furthermore, when the damping block is subjected to external impact, the force acts on it from different directions. The smaller first limiting block 21 contacts and bears a portion of the force. Due to its small area, the stress per unit area is relatively concentrated, and it transmits the force to the connected first connecting block 22. Similarly, the second limiting block 31 also bears a portion of the force and transmits it to the second connecting block 32. The larger pad 1 can receive the force transmitted from the two connecting blocks and, based on its larger area, distributes these forces more evenly, avoiding excessive stress concentration in localized areas.

[0036] Preferably, the first connecting block 22 and the second connecting block 32 are on the same central axis to uniformly transmit the force. When the damping block is subjected to a vertical impact force, whether the force is from top to bottom or bottom to top, it can pass through the corresponding limiting block and connecting block in sequence along this common central axis and finally reach the pad body 1. This avoids lateral displacement and uneven local force distribution that may occur due to asymmetrical force transmission paths, and keeps the entire damping block structure in a relatively stable state during the force transmission process.

[0037] Preferably, transition fillets 4 are provided between the first connecting block 22 and the gasket body 1, between the first connecting block 22 and the first limiting block 21, between the second connecting block 32 and the gasket body 1, and between the second connecting block 32 and the second limiting block 31. When force is transmitted through these parts, it can transition more smoothly along the fillets, so that the stress can be more evenly distributed around the connection area, avoiding excessive stress concentration at a certain point or in a certain small area, effectively enhancing the overall strength and stability of the structure, and helping to better exert the damping function of the entire damping block.

[0038] Preferably, the gasket body 1 is made of a soft, elastic material, such as rubber, to absorb and store energy. Unlike rigid materials, elastic materials do not directly transmit force upon application; instead, they buffer the force through deformation, effectively reducing the impact of the shock on the entire device and playing a crucial role in vibration damping.

[0039] Specifically, both the first limiting block 21 and the second limiting block 31 are made of relatively hard elastic materials to transmit and disperse impact forces. Compared to the softer elastic material of the gasket body 1, hard elastic materials are less prone to excessive deformation under initial stress. For example, materials like rigid polyurethane foam can maintain a relatively stable shape, allowing for better positioning and support when the shock absorber is installed and connected to external equipment, and accurately absorbing external impact forces, thus serving as a precise positioning and stress initiation point.

[0040] Specifically, when gaskets 1, first connecting block 22, first limiting block 21, second connecting block 32 and second limiting block 31 made of different materials are connected, hot pressing and adhesive bonding can be used.

[0041] Preferably, the gasket body 1, the first limiting block 21, and the second limiting block 31 are all provided with chamfered edges 5, which are used to guide and disperse the impact force. The presence of chamfered edges 5 causes the impact force to generate a certain component along the inclined surface of chamfered edges 5 when it comes into contact with the component, guiding the originally concentrated and vertical impact force to different directions, so that it no longer acts vertically on the component alone, allowing the impact force to be transmitted more smoothly on the surface and inside of the component, avoiding excessive concentration of force in a local area.

[0042] like Figure 6As shown, this type of shock absorber also includes an air cavity 6, which is disposed within the pad body 1. The air cavity 6 is used to adjust the shock absorption stiffness and reduce the mass of the pad body 1. According to the ideal gas law (PV=nRT, where P is pressure, V is volume, n is amount of substance, R is a constant, and T is temperature), under relatively stable conditions such as temperature, changes in air volume will cause changes in pressure, and these changes in pressure will react on the impact force, thus providing a buffering effect. Increasing the volume of the air cavity 6 allows for greater compressibility of air under the same impact force, resulting in a relatively softer overall characteristic of the shock absorber and a lower shock absorption stiffness, which better buffers gentler vibrations. Conversely, decreasing the volume of the air cavity 6 reduces the compressible space of air, making the shock absorber less prone to deformation under pressure, thus increasing the shock absorption stiffness, which is suitable for handling situations with larger impact forces and lower frequencies.

[0043] The weight reduction mechanism utilizes the fact that air has a much lower density than conventional elastic materials (such as rubber and polyurethane) used to make the gasket body 1. By creating an air cavity 6 within the gasket body 1, it is equivalent to replacing a portion of the original material with air, which has a lower density. This effectively reduces the overall weight of the gasket body 1 without affecting its basic shape and main function.

[0044] Specifically, one or more air cavities 6 are provided. The air cavities 6 are used to enhance the shock absorption effect while preventing excessive deformation of the gasket body 1. One or more air cavities 6 are connected by connecting strips of the gasket body 1. When vibration occurs, the gasket body 1 can deform to absorb and dampen different impact forces. The connecting strips can tighten the interior of the gasket body 1 to prevent excessive deformation.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
