Description

Technical Field

[0001] This application relates to the field of energy dissipation and vibration reduction technology, and in particular to an input displacement amplifier based on gear transmission. Background Technology

[0002] In the field of building engineering, energy dissipation and vibration reduction technology is one of the core technologies for improving the seismic and wind resistance performance of building structures. Especially in earthquake-prone areas or scenarios requiring high-intensity seismic resistance, this technology, by installing energy-dissipating dampers within the structural system, guides the energy generated by loads such as earthquakes and strong winds to the dampers for dissipation, thereby reducing the energy impact on the main structure, preventing serious structural damage, and ensuring the achievement of the seismic resistance goals of not collapsing in major earthquakes, being repairable in moderate earthquakes, and not being damaged in minor earthquakes. The effectiveness of the damper directly depends on the relative displacement it can acquire. When the inter-story displacement is small, such as in small to medium earthquakes or conventional wind-induced vibration conditions, the damper often fails to obtain sufficient excitation to fully exert its energy dissipation function.

[0003] In existing technologies, to address the problem of insufficient energy dissipation of dampers under small displacements, displacement amplification devices based on the lever principle or cantilever elbow-type viscous damper energy dissipation systems are typically employed. Among these, the lever principle displacement amplification device achieves displacement amplification through a lever arm ratio relationship, but its structural design requires a large amount of space for lever arm rotation, resulting in a relatively large overall device size, making it difficult to arrange in narrow spaces (such as building equipment mezzanines or areas with dense pipelines between columns). At the same time, lever transmission relies on hinge connections, which are prone to hinge wear and jamming after long-term use, leading to discontinuous displacement transmission and affecting amplification accuracy and stability. While the cantilever elbow-type viscous damper energy dissipation system can amplify displacement by utilizing the combined effect of structural bending deformation and inter-story shear deformation, its amplification factor depends on the deformation characteristics of the structure itself. It cannot be precisely adjusted according to the damper requirements of different projects. Moreover, the system consists of a cantilever truss, elbow support, and damper, making the overall structure complex. It has poor compatibility with different types of vibration reduction components, and the fixed support installation method makes it difficult to coordinate with diverse structural nodes. This limits the application of the device in existing building renovation and complex spatial layout scenarios.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0010] In one possible implementation, the displacement output mechanism includes a third connecting plate and a fourth connecting plate; the third connecting plate is fixedly connected to the end of the inner sliding plate away from the displacement input mechanism, and the fourth connecting plate is fixedly connected to the end of the third connecting plate away from the displacement input mechanism.

[0021] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0022] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore, repeated descriptions of them will be omitted.

[0023] This example implementation first provides an input displacement amplifier based on gear transmission. (See reference...) Figures 1 to 9 As shown, the gear-driven input displacement amplifier includes a displacement input mechanism 100, a displacement transmission mechanism 200, and a displacement output mechanism 300. Wherein: The displacement input mechanism 100 includes an input gear plate 110, two gear sets 120 of different sizes, and an output gear plate 130. The gear sets 120 of different sizes are rotatably mounted at one end of the fixed mechanism 400. The rear end of the input gear plate 110 meshes with the small gear in the two gear sets 120 of different sizes, and the front end of the output gear plate 130 meshes with the large gear in the two gear sets 120 of different sizes. The displacement transmission mechanism 200 has one end fixedly connected to the rear end of the output toothed plate 130 and is used to transmit the displacement of the output toothed plate 130. The displacement output mechanism 300 is fixedly connected at one end to the other end of the displacement transmission mechanism 200 and is used to output the displacement transmitted by the displacement transmission mechanism 200.

[0024] It should be noted that the interlayer displacement received by the input gear plate 110 is converted into rotational motion of the gear set 120 through its meshing with the small gear in the gear set 120. Since the small gear and the large gear in the gear set 120 are coaxially fixed, the large gear rotates synchronously with the small gear. Then, through the meshing of the large gear with the output gear plate 130, the rotational motion is converted back into linear displacement. The entire process utilizes the radius ratio of the large and small gears in the gear set 120 to amplify the input displacement. The core is to ensure that there is no significant loss in displacement transmission through precise meshing of gears, while ensuring the stability of the amplification factor.

[0025] Furthermore, the input toothed plate 110 has a first contact element 140 at the end away from the displacement output mechanism 300.

[0026] It should be noted that the first contact element 140 serves as the interface for displacement input, used for direct rigid connection with the main building structure, such as beam nodes or column sides. Its function is to stably receive the relative displacement generated by the structure under earthquake and wind loads, providing a precise initial displacement signal to the displacement input mechanism 100. The first contact element 140 is made of high-strength metal material, which can prevent deformation or loosening during displacement transmission, ensuring that the input toothed plate 110 can synchronously follow the structural displacement movement. At the same time, it can be adjusted according to the shape of the contact position to ensure contact stability.

[0027] In one possible implementation, there are two gear sets 120, and the structure of the gear set 120 is two small gears and one large gear that are coaxially fixedly connected, and the input gear plate 110 meshes with the two small gears.

[0028] It should be noted that the two gear sets 120 are symmetrically arranged on both sides of the input gear plate 110. This symmetrical structure allows the meshing forces on the input gear plate 110 to cancel each other out, avoiding tilting or jamming of the input gear plate 110 due to unilateral force, or uneven wear of the gear sets 120, thus significantly improving the stability of the transmission process. At the same time, the coaxial design of the "double pinion and single large gear" in the gear sets 120 ensures that the rotational speeds of the pinion and large gear are completely consistent, thereby ensuring that the displacement amplification factor is uniquely determined by the radius ratio of the large and small gears, and will not cause amplification errors due to relative rotation of the gears.

[0029] Furthermore, the two pinions and one gear are arranged in the order of pinion, gear, pinion, and so on. The input gear plate 110 has a through groove in the middle of the end connected to the pinion to accommodate the gear, and the upper and lower parts mesh with the two pinions respectively.

[0030] It should be noted that the through groove at the end of the input gear plate 110 is specifically designed to avoid the large gear in the gear set 120, so that the input gear plate 110 can simultaneously mesh tightly with the two small gears of the gear set 120, forming a "double meshing transmission" structure. This structure not only improves the force transmission capacity of the input gear plate 110 and the gear set 120, but also further enhances the smoothness of motion and avoids the risk of tooth skipping that may occur with single-tooth meshing.

[0031] In one possible implementation, the displacement transmission mechanism 200 includes a first connecting plate 210, a second connecting plate 220, an inner sliding plate 230, a first friction plate 240, and a second friction plate 260. The first connecting plate 210 has two first friction plate baffles 211 on the side near the second connecting plate 220, and the second connecting plate 220 has two second friction plate baffles 221 on the side near the first connecting plate 210. The inner sliding plate 230 has an inner sliding plate groove 231, and the upper and lower surfaces have first friction plates 240 and second friction plates 260 respectively. The first friction plate 240 is engaged between the two first friction plate baffles 211, and the second friction plate 260 is engaged between the two second friction plate baffles 221. At the same time, the first connecting plate 210 and the second connecting plate 220 are connected to the inner sliding plate 230 by a connecting bolt 250 passing through the inner sliding plate groove 231.

[0032] It should be noted that the core function of the first friction plate baffle 211 and the second friction plate baffle 221 is to fix the positions of the first friction plate 240 and the second friction plate 260, preventing the friction plates from shifting laterally during displacement transmission. This ensures that the force transmission between the first connecting plate 210, the second connecting plate 220, and the inner sliding plate 230 is entirely achieved through the friction plates, while also ensuring the stability of the friction force. The inner sliding plate groove 231 on the inner sliding plate 230 provides linear sliding space for the connecting bolt 250, allowing the inner sliding plate 230 to slide relative to the first connecting plate 210 and the second connecting plate 220 in the displacement direction. The connecting bolt 250, on the other hand, restricts the relative rotation of the three components, ensuring that the displacement transmission always proceeds in a linear direction and avoiding directional deviation. The entire displacement transmission mechanism 200 achieves smooth displacement transmission and, through the setting of the friction plates, possesses a certain buffering and adjustment capability, which can accommodate minor installation errors.

[0033] In one possible implementation, the displacement output mechanism 300 includes a third connecting plate 310 and a fourth connecting plate 320; the third connecting plate 310 is fixedly connected to the end of the inner sliding plate 230 away from the displacement input mechanism 100, and the fourth connecting plate 320 is fixedly connected to the end of the third connecting plate 310 away from the displacement input mechanism 100.

[0034] It should be noted that the third connecting plate 310 is directly fixed to the inner sliding plate 230, receiving the amplified displacement transmitted through the displacement transmission mechanism 200; the fourth connecting plate 320 serves as a transition component connecting to the damper. Through its two-section connection design, the length or connection angle of the third connecting plate 310 and the fourth connecting plate 320 can be flexibly adjusted according to the installation position and angle requirements of the damper in actual engineering projects, significantly improving the compatibility of the device with different types of dampers. Simultaneously, both connecting plates are made of rigid material, ensuring that the amplified displacement can be transmitted to the damper completely and without loss.

[0035] Furthermore, the fourth connecting plate 320 has a second contact 330 at the end away from the displacement input mechanism 100.

[0036] It should be noted that the second contact 330 serves as the interface for displacement output, used for rigid connection with the energy-dissipating damper. Its function is to accurately transmit the amplified displacement transmitted by the displacement output mechanism 300 to the damper, driving the damper to dissipate energy through friction, viscous deformation, and other methods. The structural design of the second contact 330 matches the connection end of the damper and is made of wear-resistant material, capable of withstanding the reaction force generated by the damper during operation. This prevents loosening of the connection or wear of components after long-term use, extending the overall service life of the device.

[0037] In one possible implementation, the output tooth plate 130 is fixedly connected to the first connecting plate 210 and the second connecting plate 220 by a first fixing bolt 500, and the third connecting plate 310 is fixedly connected to the inner sliding plate 230 by a second fixing bolt 600.

[0038] It should be noted that the first fixing bolt 500 ensures the robustness of force transmission among the three components, preventing the displacement of the output toothed plate 130 from being unable to be synchronously transmitted to the first connecting plate 210 and the second connecting plate 220. It also features detachability, facilitating adjustments to relative positions during on-site installation and commissioning, or replacement of components during later maintenance. Similarly, the second fixing bolt 600 ensures both robust force transmission and flexible detachment. The rigid connection ensures that the displacement of the inner sliding plate 230 can be fully transmitted to the third connecting plate 310 without displacement loss. The detachable bolt connection method has lower requirements for construction precision; during on-site installation, the installation angle or position of the third connecting plate 310 can be finely adjusted according to the actual position of the damper, adapting to different installation scenarios. Furthermore, the second fixing bolt 600 can also employ an anti-loosening design to prevent long-term vibration from causing the bolt to loosen and affecting the displacement transmission accuracy.

[0039] In one possible implementation, the fixing mechanism 400 includes a first fixing plate 410, a second fixing plate 420, and two fixing side plates 430; the first fixing plate 410 and the second fixing plate 420 are respectively fixedly disposed on the upper and lower parts of the two fixing side plates 430 near the end of the displacement input mechanism 100; the two large and small gear sets 120 are respectively rotatably disposed between the first fixing plate 410 and the second fixing plate 420, near both sides of the two fixing side plates 430.

[0040] It should be noted that the first fixing plate 410, the second fixing plate 420, and the two fixing side plates 430 together form a stable mounting base, providing reliable rotational support for the large and small gear sets 120. The two ends of the rotating shaft of the large and small gear sets 120 are respectively connected to the first fixing plate 410 and the second fixing plate 420, ensuring that there is no significant shaking or deviation when the large and small gear sets 120 rotate. At the same time, the fixing mechanism 400 as a whole can be fixed to the building structure (such as the web of a mezzanine beam or the middle of a frame column) with bolts, which is suitable for new buildings or renovations of existing buildings. The two fixing side plates 430 also protect the large and small gear sets 120, preventing dust and debris from entering the gear meshing area and affecting the transmission accuracy, while preventing personnel from accidentally touching moving parts, thus improving the safety of the device.

[0041] Working principle: When the building structure experiences interstory relative displacement under external loads, this displacement is first transmitted to the input gear plate 110 through the first contact member 140 at the end of the input gear plate 110 away from the displacement output mechanism 300. The first contact member 140 is rigidly connected to the main structure to ensure lossless displacement input. The rear end of the input gear plate 110 meshes with the small gear in the two gear sets 120. While moving linearly with the structural displacement, it drives the gear sets 120 to rotate around the axis of the fixing mechanism 400. The fixing mechanism 400 consists of a first fixing plate 410, a second fixing plate 420, and two fixing side plates 430. The first fixing plate 410 and the second fixing plate 420 are respectively fixed to the upper and lower parts of the fixing side plate 430 near the displacement input mechanism 100, providing stable rotational support for the gear sets 120 and preventing gear offset during rotation. Since the gear set 120 adopts a coaxial fixed design of double pinions and single large gear, the rotation of the pinions will synchronously drive the coaxial large gear to rotate. According to the principle that the linear displacement of gear transmission is proportional to the radius, the circumferential tangential displacement of the large gear is a multiple of the radius of the pinion. For example, when the radius of the large gear is 2 to 3 times that of the pinion, the displacement is amplified by 2 to 3 times, realizing the precise amplification of the input displacement. Then, the large gear meshes with the front end of the output gear plate 130, converting the rotational motion back into the linear displacement of the output gear plate 130. The rear end of the output toothed plate 130 is fixed to the first connecting plate 210 and the second connecting plate 220 of the displacement transmission mechanism 200 by the first fixing bolt 500, so as to transmit the amplified displacement to the displacement transmission mechanism 200. In this mechanism, the first connecting plate 210 is provided with two first friction plate baffles 211 on the side near the second connecting plate 220, and the second connecting plate 220 is provided with two second friction plate baffles 221 on the corresponding side. The first friction plates 240 and the second friction plates 260 on the upper and lower surfaces of the inner slide plate 230 are respectively locked between the corresponding baffles. The connecting bolt 250 passes through the inner slide plate groove 231 of the inner slide plate 230 to connect the three, which not only restricts relative rotation to ensure linear transmission, but also provides sliding space for the inner slide plate 230 through the groove, so as to realize smooth displacement transmission. Finally, the end of the inner slide plate 230 away from the displacement input mechanism 100 is fixed to the third connecting plate 310 of the displacement output mechanism 300 by the second fixing bolt 600. The displacement is transmitted to the fourth connecting plate 320 through the third connecting plate 310, and then transmitted to the damper (such as a friction damper or a viscous damper) by the second contact member 330 away from the input end of the fourth connecting plate 320, driving the damper to dissipate energy.

[0042] In terms of layout, such as Figure 9As shown, this device, with its compact structure, can adapt to narrow or complex spaces. For example, in the equipment mezzanine of an existing building, filled with air conditioning ducts and cable trays, with only redundant gaps on the beam sides and column corners, the fixing side plate 430 of the fixing mechanism 400 can be fixed to the web of the mezzanine beam with bolts. In the column space of an underground garage, with fire sprinkler pipes on the top and drainage ditches on the ground, and only transverse gaps in the middle of the column, a diagonal bracing arrangement can be used to fix the fixing mechanism 400 to the middle of the frame column. At the same time, the power transmission direction can be changed by adjusting the design of the large and small gear sets 120, so that the placement direction of the damper body is different from the direction of structural displacement, further adapting to the spatial layout requirements. Moreover, the whole is connected by bolts, which has low requirements for construction precision and is convenient for on-site installation and later maintenance.
