Description

Technical Field

[0001] The utility model relates to the technical field of energy dissipation and shock absorption of building structures, in particular to a displacement amplification and shock absorption device. Background Art

[0002] Building structures are prone to damage or collapse in earthquake disasters, resulting in significant loss of life and property. In other words, earthquakes themselves are not the main cause of economic losses and casualties; rather, earthquakes cause damage and collapse of structures and buildings, resulting in economic losses and casualties. Therefore, mitigating earthquake disasters can begin by studying their seismic performance and improving the seismic performance of structures. In recent years, energy dissipation and shock absorption technology has become an important development trend in the field of seismic design of building structures. By installing energy dissipation and shock absorption devices in building structures, the seismic energy input into the structure can be dissipated in another way, thereby reducing or preventing damage to the building structure and achieving the purpose of shock absorption.

[0003] In recent years, shock absorption technology has been used in high-rise buildings and reinforcement and renovation projects, and is considered to be a means to effectively match the seismic response of building structures. However, the small inter-story displacement of rigid structures under earthquakes limits the movement of the damper, resulting in poor hysteresis energy dissipation of dampers under traditional installation forms (such as herringbone supports or diagonal supports). A large number of studies have shown that different damper installation methods and constraints have a great influence on the movement of their two ends. Therefore, the development of a damper shock absorption system with a displacement amplification mechanism and its related design theory has very important engineering practical value and engineering significance.

[0004] However, the existing technology requires a large number of dampers to achieve the required functions; and most of the shock absorbing devices in the existing technology use mechanical parts to achieve shock absorption, and there are no relevant maintenance measures, which easily cause the mechanical parts to rust, etc., making the transmission efficiency between the mechanical parts low, thereby affecting the shock absorption effect. Utility Model Content

[0005] The utility model provides a displacement amplification and shock absorption device, which can realize displacement amplification and reduce the number of dampers on the one hand; and can maintain mechanical parts on the other hand, extend the service life of the mechanical parts and improve the shock absorption efficiency.

In this case, due to the cooperation between the second active member and the first driven member, the displacement of the second driven member in the first direction is greater than the displacement of the first active member, thereby causing the input displacement of the shock absorber to be greater than the displacement of the first wall panel in the first direction.

The auxiliary member is provided with a receiving chamber containing lubricant. When the driver moves with the input end of the shock absorber, the driver moves within the receiving chamber and squeezes the lubricant through the connecting tube onto the second active member and the first driven member, thereby lubricating the second active member and the first driven member.

[0028] The present application provides a displacement amplifying and damping device, referring to Figure 1 , Figure 1 The overall structure of the displacement amplifying and shock absorbing device is shown. The displacement amplifying and shock absorbing device includes: a shock absorbing assembly 1, a displacement amplifying assembly 2, and an auxiliary assembly 3. The shock absorbing assembly 1 has one end connected to the first wall panel 4, and the end of the shock absorbing assembly 1 away from the first wall panel 4 is connected to the second wall panel 5. The displacement amplifying assembly 2 is mounted on the second wall panel 5 at a position corresponding to the shock absorbing assembly 1, and the displacement amplifying assembly 2 is connected to the shock absorbing assembly 1. When the first wall panel 4 is subjected to an earthquake, the displacement amplifying assembly 2 amplifies the horizontal displacement of the first wall panel 4 and transmits the amplified displacement to the shock absorbing assembly 1, thereby increasing the displacement at the input end of the shock absorbing assembly 1. The auxiliary assembly 3 has one end disposed at the input end of the shock absorbing assembly 1 and the other end disposed on the displacement amplifying assembly 2 at a position corresponding to the shock absorbing assembly 1. When the input end of the shock absorbing assembly 1 undergoes relative motion, the auxiliary assembly 3 can move relative to the displacement amplifying assembly 2, thereby maintaining the displacement amplifying assembly 2.

[0029] In the embodiment of the present application, the shock absorbing assembly 1 is provided with a structure that can be connected to the first wall panel 4 and the second wall panel 5, and the shock absorbing assembly 1 is installed on the second wall panel 5 through the structure.

[0030] For example, some structures in the shock-absorbing assembly 1 may be provided with mounting holes, and corresponding components may be mounted on the first wall panel 4 or the second wall panel 5 through the mounting holes.

[0031] As another example, the shock absorbing assembly 1 may include different parts, and the different parts may be installed in their respective corresponding positions to achieve displacement amplification and shock absorption functions.

[0032] In an embodiment of the present application, the displacement amplification component 2 can be installed between the first wall panel 4 and the second wall panel 5, and the displacement amplification component 2 can be set between different components in the shock-absorbing component 1, so as to amplify the displacement of the first wall panel 4 and transmit the amplified displacement to the shock-absorbing component 1.

[0033] Exemplarily, the displacement amplification component 2 has a structure capable of being connected to the second wall panel 5. For example, the displacement amplification component 2 is installed on the second wall panel 5 by providing a connection method of embedded parts.

[0034] As another example, the displacement amplification component 2 has a structure that can be connected to the shock absorbing component 1 , for example, a structure such as a slide groove and a through hole that matches the shock absorbing component 1 is provided.

[0035] As another example, the displacement amplification component 2 is provided with a structure capable of amplifying the displacement in the horizontal direction, for example, a gear rack combination, a lever structure, or the like that can achieve a displacement amplification effect.

[0036] In the embodiment of the present application, the auxiliary component 3 can be arranged between the first wall panel 4 and the second wall panel 5, and located between the shock absorbing component 1 and the displacement amplifying component 2.

[0037] Exemplarily, corresponding parts in the auxiliary component 3 can be connected to corresponding parts in the shock absorbing component 1 , and corresponding parts in the auxiliary component 3 can be connected to corresponding parts in the displacement amplifying component 2 .

[0038] As another example, the auxiliary component 3 may be provided with a cleaning structure, a lubrication structure, or other structures capable of maintaining the components in the shock absorbing component 1 .

[0039] In the above embodiment, since the shock-absorbing component 1 is provided, the shock-absorbing component 1 can achieve shock absorption between building structures and provide protection for the building structure; since the displacement amplification component 2 is provided, the displacement amplification component 2 can amplify the displacement generated by the building structure when it is affected by an earthquake, and the shock-absorbing component 1 can work normally during a small or medium earthquake, and the number of shock-absorbing components 1 used can be reduced, thereby improving work efficiency; since the auxiliary component 3 is provided, the auxiliary component 3 can move relative to the displacement amplification component 2 during the operation of the shock-absorbing component 1, thereby maintaining the displacement amplification component 2 and extending the service life of the displacement amplification component 2.

[0040] In some embodiments of the present application, reference Figure 2 and Figure 3 , Figure 2The figure shows the connection structure of the shock absorbing component 1 and the auxiliary component 3. Figure 3 The diagram shows the connection structure of the shock-absorbing assembly 1 and the displacement amplifying assembly 2. The shock-absorbing assembly 1 includes a shock-absorbing member 11, one end of which is connected to a first connecting member 12, which is mounted on the second wall panel 5. The end of the shock-absorbing member 11 away from the first connecting member 12 is connected to the displacement amplifying assembly 2. The shock-absorbing member 11 also includes a second connecting member 13, which is connected to the first wall panel 4. The second connecting member 13 is connected to the displacement amplifying assembly 2.

[0041] In the embodiment of the present application, the shock absorbing assembly 1 can be configured to have a structure including a shock absorbing member 11, a first connecting member 12 and a second connecting member 13; one end of the shock absorbing member 11 can be connected to the first connecting member 12, and the other end can be connected to the corresponding part in the displacement amplification assembly 2, and the first connecting member 12 can be installed on the second wall panel 5, and support is provided to the shock absorbing member 11 through the first connecting member 12; the second connecting member 13 can be installed on the first wall panel 4, and the second connecting member 13 can be connected to the corresponding part in the displacement amplification assembly 2.

[0042] For example, the shock absorber 11 may be a viscous damper. The principle of a viscous damper is to absorb and dissipate the energy generated by structural vibration by utilizing the damping properties of viscous materials. When the structure vibrates due to external excitation, the viscous material in the viscous damper is subjected to shear forces, generating a damping force. This damping force effectively dissipates the energy of the structural vibration, reducing the amplitude and duration of the vibration, thereby achieving the purpose of shock absorption. The specific model of the viscous damper can be selected based on the actual usage scenario.

[0043] As another example, the first connecting member 12 can be a damper connecting ear plate or other parts with a supporting function. Taking the first connecting member 12 as an example, the damper connecting ear plate can be rotatably connected to the viscous damper, and the damper connecting ear plate can be installed on the second wall panel 5 close to the end face of the first wall panel 4.

[0044] In another example, the second connecting member 13 may also be a damper connecting lug plate or other parts that can be connected to the displacement amplification assembly 2. Taking the second connecting member 13 as an example of a damper connecting lug plate, the damper connecting lug plate can be installed on the end surface of the first wall panel 4 close to the second wall panel 5.

[0045] In the above embodiment, since the shock-absorbing member 11 is provided, the shock-absorbing effect is achieved by the provided shock-absorbing member 11; since the first connecting member 12 is provided, the first connecting member 12 can provide support for the shock-absorbing member 11; since the second connecting member 13 is provided, by connecting the provided second connecting member 13 and the displacement amplification component 2, the displacement generated by the first wall panel 4 can be transmitted to the displacement amplification component 2, and then the displacement of the first wall panel 4 can be amplified by the displacement amplification component 2.

[0046] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the displacement amplification component 2 includes a base and a transmission component; the transmission component includes a first active member 21, the first active member 21 is connected to the second connecting member 13, the first active member 21 is engaged with the second active member 22, the second active member 22 is connected to the first follower 23, the first follower 23 is engaged with the second follower 24, and the second follower 24 is connected to the shock absorber 11; the first active member 21, the second active member 22, the first follower 23, and the second follower 24 are all connected to the base; wherein, through the cooperation of the second active member 22 and the first follower 23, along the first direction A, the displacement of the second follower 24 is greater than the displacement of the first active member 21, so that the input displacement of the shock absorber 11 is greater than the displacement of the first wall panel 4 in the first direction A.

[0047] Illustratively, the first active member 21 may be a first rack, the second active member 22 may be a first gear, the first driven member 23 may be a second gear, and the second driven member 24 may be a second rack.

[0048] Among them, the first rack can be slidably connected to the base, and the first rack can be engaged with the first gear; a connecting block can be provided between the first rack and the second connecting member 13, one end of the connecting block can be connected to the first rack, and the other end of the connecting block can be rotatably connected to the second connecting member 13, and the first rack and the second connecting member 13 are connected through the connecting member.

[0049] Alternatively, the first gear can be connected to a rotating shaft, the second gear is connected to the rotating shaft, the rotating shaft is rotatably connected to the base, and the rotating shaft is supported by the base. When the first gear rotates, it can drive the second gear to rotate synchronously through the rotating shaft; the axes of the first gear, the second gear, and the rotating shaft coincide, or are close to coincide.

[0050] Furthermore, the second gear can be engaged with the second rack, the second rack is slidably connected to the base, and the second rack is connected to the input end of the shock absorber 11, so that the shock absorber 11 can be driven to move by the second rack.

[0051] It should be noted that the first and second gears are coaxially arranged, but their diameters are different, with the first gear's diameter being smaller than the second's. In the present embodiment, there are no specific limitations on the diameters of the first and second gears. The first gear's diameter is smaller than the second gear's diameter, and the displacement of the first wall panel 4 can be amplified by the second gear and the second rack. The specific amplification factor can be adjusted based on the dimensions of the first and / or second gears in accordance with actual circumstances.

[0052] In the above embodiment, since a base is provided, the base provides support and protection for the transmission component, thereby reducing the probability of the transmission component being damaged by external factors; since a transmission component is provided, the transmission component can amplify the displacement generated by the first wall panel 4, and transmit the amplified displacement to the shock absorbing component 1, thereby realizing the function of displacement amplification, with a simple structure, flexibility and convenience.

[0053] In some embodiments of the present application, Figure 3 As shown, the base includes a shell 25 and a support member 26; the shell 25 is connected to the second wall panel 5, and the support member 26 is installed inside the shell 25; the first active member 21 and the second driven member 24 are both slidingly connected to the shell 25, and the second active member 22 and the first driven member 23 are rotationally connected to the shell 25.

[0054] In this embodiment of the present application, the base can be configured as a structure including a housing 25 and a support member 26. The housing 25 can be mounted on the second wall panel 5, and the support member 26 is installed within the housing 25 at a position corresponding to the displacement amplification assembly 2. The first active member 21 can be slidably connected to the housing 25, and the second driven member 24 can slide on the support member 26 and the housing 25. The second active member 22 and the first driven member 23 can be rotatably connected to the housing 25.

[0055] For example, the housing 25 can be a protective shell, shield, or other component with a cavity, and a portion of the displacement amplification assembly 2 can be placed within the cavity. The housing 25 can be pre-embedded or otherwise mounted on the second wall panel 5 near one end of the first wall panel 4, and the housing 25 is positioned between the first connector 12 and the second connector 13.

[0056] The shell 25 can be made of steel or other materials. In the embodiment of the present application, there is no specific restriction on the material of the shell 25. It only needs to have certain supporting and protective capabilities and meet the construction requirements.

[0057] In another example, the support member 26 may be a support plate, which may be integrally formed with the housing 25 or connected to the housing 25 by welding or other methods. The support plate may be made of steel or other materials that meet the requirements.

[0058] Furthermore, a slot may be provided on the support plate, and the shape of the slot may match the shape of the second rack, so that the second rack can slide in the slot, thereby improving the stability of the second rack during sliding.

[0059] In the above embodiment, since a shell 25 is provided, the shell 25 can protect part of the structure in the displacement amplification component 2, reduce the probability of part of the structure in the displacement amplification component 2 being damaged due to external factors, and extend the service life of the parts; since a support member 26 is provided, the support member 26 provides support to the second follower 24, thereby improving the stability of the second follower 24 during movement.

[0060] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the auxiliary component 3 includes an auxiliary part 31, the auxiliary part 31 is connected to the shock absorber 11, the input end of the shock absorber 11 is connected to the driving part 32, and the driving part 32 is connected to the auxiliary part 31; the auxiliary part 31 is installed with a connecting pipe 33, and the end of the connecting pipe 33 away from the auxiliary part 31 is installed at a position on the base corresponding to the second active part 22 and the first driven part 23.

[0061] Among them, the auxiliary part 31 is provided with a accommodating cavity, and a lubricant is provided in the accommodating cavity. When the driving part 32 moves with the input end of the shock absorber 11, the driving part 32 moves in the accommodating cavity and squeezes the lubricant through the connecting tube 33 to the second active part 22 and the first driven part 23, thereby achieving lubrication of the second active part 22 and the first driven part 23.

[0062] Exemplarily, the auxiliary component 31 can be a part with an accommodation space. For example, the auxiliary component 31 can be a sleeve, a box, or other parts.

[0063] In another example, taking the auxiliary member 31 as a sleeve, the axial direction of the sleeve is parallel or nearly parallel to the first direction A. That is, the axial direction of the sleeve is parallel or nearly parallel to the movement direction of the second follower 24 .

[0064] The sleeve can be mounted on the shock absorber 11 by bolting, snapping, or other connection methods. This arrangement facilitates installation and removal of the sleeve. A driving member 32 is provided between the sleeve and the input shaft of the shock absorber 11. The driving member 32 can be an "L"-shaped rod. One end of the driving member 32 is connected to the output shaft of the shock absorber 11, and the other end is inserted into the sleeve. A push plate 321 is provided at the end of the driving member 32 located within the sleeve. The size of the push plate 321 matches the size of the inner wall of the sleeve. The push plate 321 can slide within the sleeve as the driving member 32 moves.

[0065] It is understood that lubricant may be provided within the sleeve, and a connecting tube 33 may be inserted into the sleeve. The other end of the connecting tube 33 may be inserted into a side of the base body near the first wall panel 4, that is, the other end of the connecting tube 33 is positioned above the first and second gears. A sealing gasket may be provided between the driving member 32 and the sleeve to reduce the probability of lubricant leaking from the sleeve during movement of the driving member 32.

[0066] It needs to be explained that, Figure 4 As shown, during the process of manufacturing the first gear and the second gear, the thickness of the first gear and the second gear can be appropriately increased according to the matching and installation relationship between the specific parts, so that the lubricant dripping from the connecting pipe 33 arranged above the first gear and the second gear can fall onto the first gear and the second gear, thereby lubricating the first gear and the second gear.

[0067] Furthermore, the connecting tube 33 and the housing 25 can be loosely fitted, allowing for a small relative movement of the connecting tube 33 within the housing 25 without affecting the lubrication of the first and second gears. The housing 25 can be configured as a spliced structure, which can be understood as comprising an opening with a removable cover plate attached to the opening, sealing the housing 25. A collection box is provided at the bottom of the housing 25 to collect lubricant dripping from the first and second gears for periodic cleaning.

[0068] In another example, since the second follower 24 can slide on the housing 25 along the first direction A, and since the first wall panel 4 may reciprocate along the first direction A, a support box 35 can be installed on the side of the housing 25 away from the shock absorber 11. The end of the second follower 24 away from the shock absorber 11 can be connected to a slide bar 34. The slide bar 34 can move along with the second follower 24 through the housing 25. The slide bar 34 is connected to a slide plate (not shown in the figure) that can slide within the support box 35. Lubricant is placed in the support box 35, and a liquid outlet pipe 36 is inserted into the support box 35. The end of the liquid outlet pipe 36 away from the support box 35 is inserted into the housing 25. When the slide slides in the support box 35 toward the liquid outlet pipe 36, the lubricant in the support box 35 can be squeezed onto the second active member 22 and the first driven member 23 through the liquid outlet pipe 36, thereby lubricating the first active member 21, the second active member 22, the first driven member 23 and the second driven member 24.

[0069] The outlet ends of the connecting pipe 33 and the liquid outlet pipe 36 may be provided with nozzles to expand the liquid coverage of the outlet ends so that the lubricant can be coated on the second active member 22 and the first driven member 23 .

[0070] In the above embodiment, since the auxiliary component 3 is provided, when the shock absorber 11 moves, it can drive the driving member 32 to move. The driving member 32 squeezes the lubricant in the auxiliary member 31 to the second active member 22 and the first driven member 23 through the connecting tube 33. During the rotation of the first gear, the lubricant can contact the first rack, and during the rotation of the second gear, the lubricant can contact the second rack; thereby achieving lubrication of the mechanical parts and extending the service life of the mechanical parts.

[0071] The following describes the use of a displacement amplification and shock absorption device provided by this application. When in use:

[0072] S100: When the first wall panel 4 is subjected to an earthquake, the first wall panel 4 is displaced in the first direction A. The first wall panel 4 drives the second connecting member 13 to move, the second connecting member 13 drives the first active member 21 to move, the first active member 21 drives the second active member 22 to rotate, the second active member 22 drives the first driven member 23 to rotate, the first driven member 23 drives the second driven member 24 to move, the second driven member 24 slides on the support member 26, and the second driven member 24 drives the input end of the shock absorber 11 to move. The displacement generated by the movement of the second driven member 24 is greater than the displacement generated by the movement of the first active member 21, thereby increasing the input displacement of the shock absorber 11.

[0073] S200: While the second follower 24 drives the input end of the shock absorber 11 to move, the input end of the shock absorber 11 can drive the driving member 32 to move. The driving member 32 drives the push plate 321 to slide in the auxiliary member 31. The push plate 321 squeezes the lubricant in the auxiliary member 31. The lubricant in the auxiliary member 31 flows out to the second active member 22 and the first follower 23 through the connecting pipe 33, lubricating the first active member 21, the second active member 22, the first follower 23 and the second follower 24.

[0074] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations.
