Description

Technical Field

[0001] This utility model relates to the field of seismic isolation and control of engineering structures, and in particular to a combined multi-directional rolling energy-dissipating metal damper device. Background Technology

[0002] Rolling energy-dissipating metal dampers (such as U-type, C-type, and V-type dampers) possess excellent energy dissipation characteristics and are widely used in the field of seismic isolation and control technology for engineering structures. These metal dampers are often used as unidirectional energy-dissipating metal dampers, typically fixed directly to the energy-dissipating nodes using bolts or welding. As the performance of these dampers gains widespread recognition, their application areas continue to expand.

[0003] Because bridges and building structures have inherently different characteristics in three spatial directions, existing dampers cannot solve the problem of varying energy dissipation parameters in these three directions. Publication No. CN213233115U describes a metal damper device capable of three-dimensional deformation, comprising at least two metal dampers. The upper part of the metal damping unit is fixedly connected to the bridge beam, and the lower connecting plate is fixedly connected to the bridge pier. At least one metal damping unit slides along the longitudinal direction of the bridge with the lower connecting plate, and at least one metal damping unit in the remaining metal dampers slides along the transverse direction of the bridge with the lower connecting plate. This structure enables the metal dampers to undergo shear deformation in three directions without interference. However, this solution requires at least two metal dampers, and each damper needs to be connected to the bridge beam and pier separately. When subjected to vertical loads, the metal dampers are prone to interference with the tension plate during horizontal deformation. Furthermore, it requires significant space and is inconvenient to install.

[0004] Therefore, how to use this type of damper at a node to dissipate energy in any direction in the horizontal plane and avoid interference with the tensile plate when the metal damper is subjected to rolling deformation under pressure has become an urgent problem to be solved. Summary of the Invention

[0005] In view of this, the present invention aims to propose a combined multi-directional rolling energy-dissipating metal damper device, which solves the problem that a single metal energy-dissipating damper can dissipate energy in any direction in the horizontal plane while avoiding the problem that the metal damper may move under pressure and interfere with the tension plate.

[0006] In the prior art, two or more metal dampers are placed in different directions to dissipate energy in any direction in the horizontal plane. The two metal dampers are set as an integrated structure and share an upper and lower connecting plate. In order to enable the upper connecting plate to move in any direction in the horizontal plane, this application proposes a new type of guiding device, which adopts four sets of I-shaped sliders combined with a ring-shaped guide plate, making it possible to combine multiple unidirectional dampers for parallel coupling.

[0007] Traditional coupled unidirectional energy-dissipating dampers use a T-shaped slider with a ring-shaped guide plate as the motion bracket, which presents a problem. As a rolling energy-dissipating metal damper, it rolls forward when deforming and dissipating energy. Due to the bending moment, the damper presses against the ring-shaped guide plate. When the damper needs to slide freely along the guide groove, it is affected by the frictional resistance between the damper and the ring plate, causing the damper to twist perpendicular to the main energy-dissipating direction (rolling direction). The damper cannot roll and deform smoothly, severely affecting its energy-dissipating performance. This application replaces the T-shaped slider with an I-shaped slider. The I-shaped embedded plate slides inside the ring-shaped guide plate, and the exposed I-shaped plate slides on top of the ring-shaped guide plate. The U-shaped metal damper rolls on the exposed plate, eliminating motion interference with the ring plate.

[0008] Simply changing a T-shaped structure to an I-shaped structure increases the structural height and cost. In existing technologies, when the metal damper undergoes rolling deformation, the T-shaped slider generates a lateral moment under stress. The flanges of the T-shaped slider exert forces on the circumferential tensile structure. At this point, the top of the circumferential tensile structure is indeterminate, operating in a cantilever beam state. To improve structural stability, the thickness of the circumferential tensile structure is typically increased. To address the issue of increased structural height due to the I-shaped structure, this application reduces the thickness of the circumferential tensile structure and divides the I-shaped structure into two parts: an exposed translational sliding plate and an embedded T-shaped slider. These are connected by bolts, and prestress is applied to increase the constraint around the circumferential tensile structure. This transforms the stress state of the circumferential tensile structure from a cantilever beam state to a statically indeterminate cantilever beam state with bottom support, without increasing the structural height while altering the tensile structure thickness.

[0009] The technical solution of this utility model is as follows: a combined multi-directional rolling energy-dissipating metal damper device, comprising a first motion coupling bracket, a metal damper, and a second motion coupling bracket arranged sequentially from bottom to top;

[0010] The first motion coupling bracket and the second motion coupling bracket have the same structure. The first motion coupling bracket and the second motion coupling bracket are arranged opposite to each other, so that the metal damper can slide relative to the first motion coupling bracket and the second motion coupling bracket without interfering with the first motion coupling bracket.

[0011] The two ends of the metal damper are respectively connected to the first motion coupling bracket and the second motion coupling bracket. At least two metal dampers are provided, and the working directions of the two or more metal dampers are set to two mutually perpendicular directions. The working direction of the metal damper is perpendicular to the sliding direction of the metal damper.

[0012] Furthermore, the first motion coupling bracket includes a base, a first guide plate assembly, and a second guide plate assembly. The guiding direction of the first guide plate assembly is perpendicular to the guiding direction of the second guide plate assembly, and the first guide plate assembly and the second guide plate assembly are disposed on the base.

[0013] Furthermore, the second motion coupling bracket includes an upper seat plate, a third guide plate assembly, and a fourth guide plate assembly. The guiding direction of the third guide plate assembly is perpendicular to the guiding direction of the fourth guide plate assembly, and the third guide plate assembly and the fourth guide plate assembly are disposed on the upper seat plate.

[0014] Furthermore, the metal damper includes a first metal damper and a second metal damper. The two ends of the first metal damper are respectively connected to the first guide plate assembly and the third guide plate assembly, and the two ends of the second metal damper are respectively connected to the second guide plate assembly and the fourth guide plate assembly. The working direction of the first metal damper is perpendicular to the working direction of the second metal damper.

[0015] Furthermore, the base is plate-shaped, and a groove is provided at the bottom of the base. A through hole is provided in the groove of the base for convenient connection of the first guide plate assembly or the second guide plate assembly.

[0016] Furthermore, the first guide plate assembly includes two first guide plates, a first slider, and a limiting block. The cross-section of the first guide plate is inverted L-shaped, and the cross-section of the first slider is I-shaped. The two first guide plates are disposed opposite to each other on both sides of the waist plate of the first slider to guide the first slider to slide between the two first guide plates. The limiting block is used to restrict the displacement of the first slider.

[0017] Furthermore, the first slider includes a flat plate and a T-shaped plate, wherein the flat plate and the web of the T-shaped plate are connected by bolts.

[0018] Furthermore, the metal damper is a rolling deformation energy-dissipating metal damper, and the metal damper is one of U-type, C-type and V-type dampers.

[0019] Furthermore, the metal damper is connected to the T-plate via the bolts and the pressure plate.

[0020] Furthermore, the upper and lower flanges of the first slider are respectively in close contact with the upper and lower surfaces of the horizontal portions of the two first guide plates.

[0021] Compared with existing technologies, the combined multi-directional rolling energy-dissipating metal damper device of this utility model has the following advantages:

[0022] 1. This utility model proposes a novel guiding device that uses four sets of I-shaped sliders combined with a circumferential tensile guide plate to connect two unidirectional energy-dissipating dampers in the prior art into an integrated structure, thereby solving the problem that unidirectional energy-dissipating dampers can only dissipate energy in one direction, and realizing that the damper can deform and dissipate energy in any direction within the horizontal plane.

[0023] 2. This utility model replaces the T-shaped slider with an I-shaped slider. The I-shaped embedded plate slides inside the circumferential guide plate, and the exposed I-shaped plate slides on the top of the circumferential guide plate. The U-shaped metal damper rolls on the upper part of the exposed plate, so there will be no motion interference between it and the circumferential plate.

[0024] 3. This utility model reduces the plate thickness at the tensile structure of the circumferential plate and divides the I-shaped structure into two parts. The I-shaped structure is then connected as a whole by bolts, and prestress is applied to increase the constraint around the tensile structure of the circumferential plate. This changes the stress state of the tensile structure of the circumferential plate from a cantilever beam state to a constrained cantilever beam state. The structural height will not increase if the T-shaped slider is replaced with an I-shaped slider. Attached Figure Description

[0035] This utility model discloses a combined multi-directional rolling energy-dissipating metal damper device, including...

[0036] The first motion coupling bracket 1, the metal damper 2, and the second motion coupling bracket 3 are arranged sequentially from bottom to top;

[0037] The first motion coupling bracket 1 and the second motion coupling bracket 3 have the same structure. The first motion coupling bracket 1 and the second motion coupling bracket 3 are symmetrically arranged to enable the metal damper 2 to slide relative to the first motion coupling bracket 1 and the second motion coupling bracket 3 without interfering with the first motion coupling bracket 1.

[0038] The two ends of the metal damper 2 are respectively connected to the first motion coupling bracket 1 and the second motion coupling bracket 3. At least two metal dampers 2 are provided. The working directions of the two or more metal dampers 2 are set to two mutually perpendicular directions. The working direction of the metal damper 2 is perpendicular to the sliding direction of the metal damper 2.

[0039] When the structure is subjected to external forces such as earthquakes and wind, the metal damper 2 absorbs and dissipates energy through plastic deformation, thereby reducing the dynamic load transmitted to the building or structure. Due to the use of transverse and longitudinal guide plate assemblies, the two unidirectional energy dissipation dampers in the prior art are connected into an integrated structure, solving the problem that unidirectional energy dissipation dampers can only dissipate energy in one direction. This allows the damper to deform and dissipate energy in any direction within the horizontal plane. The device can provide effective energy dissipation in multiple directions, enhancing its adaptability to external forces in different directions. The symmetrical design of the first motion coupling bracket 1 and the second motion coupling bracket 3 ensures that when the structure undergoes relative displacement, the motion can be effectively transmitted to the metal damper 2 to realize its energy dissipation function, ensuring the stability and reliability of the entire system.

[0040] The presence of the first motion coupling bracket 1 and the second motion coupling bracket 3 in this configuration, which divides the metal damper 2 into two working directions, can effectively cope with forces from multiple directions, provide more comprehensive protection, ensure uniform force distribution, and improve the stability and consistency of the system response.

[0041] Specifically, the first motion coupling bracket 1 includes a base 101, a first guide plate assembly 102 and a second guide plate assembly 103. The guiding direction of the first guide plate assembly 102 is perpendicular to the guiding direction of the second guide plate assembly 103. The first guide plate assembly 102 and the second guide plate assembly 103 are disposed on the base 101.

[0042] The first guide plate assembly 102 is configured to guide in a lateral direction, and the second guide plate assembly 103 is configured to guide in a longitudinal direction. The first guide plate assembly 102 and the second guide plate assembly 103 provide guiding functions in two mutually perpendicular directions, enabling the coupling bracket to handle relative displacement in both the lateral and longitudinal directions simultaneously.

[0043] The base 101 provides a solid foundation for the entire coupling bracket, ensuring the stability of the guide plate assembly during operation and allowing forces from different directions to be evenly transmitted to the bottom structure.

[0044] This setup optimizes the layout between the base 101 and the guide plate assembly. The precise manufacturing of the first guide plate assembly 102 and the second guide plate assembly 103 ensures linearity and accuracy of movement, enabling efficient multi-directional motion control within a limited space. It is suitable for applications with limited space. The prefabricated guide plate assembly can be directly installed onto the base 101, simplifying the on-site assembly process. At the same time, the modular design also facilitates later inspection and maintenance.

[0045] Specifically, the first guide plate assembly 102 and the second guide plate assembly 103 have the same structure.

[0046] The first guide plate assembly 102 and the second guide plate assembly 103 are completely identical in size, shape, material selection, and manufacturing process. They are respectively set on the base 101 and their working directions are perpendicular to each other, ensuring that the movement in different directions is coordinated and consistent, avoiding unexpected movement caused by differences between components, improving the operational stability of the entire system, and handling relative displacement in both lateral and longitudinal directions, providing comprehensive motion control capabilities. This arrangement not only simplifies the design and manufacturing process, but also allows them to be interchanged when necessary, increasing the system's flexibility and reducing installation difficulty, because installers only need to be familiar with one type of component to complete all installation tasks, reducing training time and error rates, which is conducive to standardized production and bulk purchasing, thereby reducing production costs and improving economic efficiency.

[0047] Because this setup uses the same materials and technical specifications, the performance difference between the two components is minimal, thereby improving the reliability and lifespan of the entire system.

[0048] Specifically, the second motion coupling bracket 3 includes an upper seat plate 301, a third guide plate assembly 302 and a fourth guide plate assembly 303. The guiding direction of the third guide plate assembly 302 is perpendicular to the guiding direction of the fourth guide plate assembly 303. The third guide plate assembly 302 and the fourth guide plate assembly 303 are disposed on the upper seat plate 301.

[0049] The third guide plate assembly 302 and the fourth guide plate assembly 303 respectively provide guiding functions in two mutually perpendicular directions, enabling the coupling bracket to handle relative displacement from different directions. Working in conjunction with the first motion coupling bracket 1, energy is dissipated through the deformation of a metal damper 2, reducing the impact of external forces on the entire system, especially in the event of earthquakes or strong winds. Another metal damper 2 slides within the third guide plate assembly 302 or the fourth guide plate assembly 303.

[0050] The upper plate 301 serves as the base of the coupling bracket, providing a stable installation platform for the entire device and ensuring effective connection with the structure or components above.

[0051] This setup enables efficient multi-directional motion control within a limited space, making it suitable for space-constrained applications. The prefabricated guide plate assembly can be directly installed onto the base 101, simplifying the on-site assembly process. At the same time, the modular design also facilitates later inspection and maintenance.

[0052] Specifically, the metal damper 2 includes a first metal damper 201 and a second metal damper 202. The two ends of the first metal damper 201 are respectively connected to the first guide plate assembly 102 and the third guide plate assembly 302, and the two ends of the second metal damper 202 are respectively connected to the second guide plate assembly 103 and the fourth guide plate assembly 303. The working direction of the first metal damper 201 is perpendicular to the working direction of the second metal damper 202.

[0053] The first metal damper 201 connects the first guide plate assembly 102 and the third guide plate assembly 302, and the second metal damper 202 connects the second guide plate assembly 103 and the fourth guide plate assembly 303, realizing bidirectional symmetrical protection of the structure and enhancing the stability and reliability of the system. The first metal damper 201 and the second metal damper 202 respectively handle the relative displacement in the two mutually perpendicular directions of lateral and longitudinal. When the first metal damper 201 is working, it absorbs and dissipates energy through plastic deformation. The second metal damper 202 slides within the second guide plate assembly 103 and the fourth guide plate assembly 303 to avoid the second metal damper 202 bearing torque in the non-working direction.

[0054] Specifically, the base 101 is plate-shaped, with a groove at the bottom and a through hole in the groove for easy connection to the first guide plate assembly 102 or the second guide plate assembly 103.

[0055] The groove provides an accurate installation position for the first guide plate assembly 102 and the second guide plate assembly 103, ensuring the accuracy during assembly and reducing assembly errors. The through hole is located inside the groove, which can effectively protect the through hole from external environmental factors such as dust and moisture, and prevent the through hole from being damaged during transportation or construction. It can also provide sufficient embedding depth without increasing the overall height, facilitating a stable connection between the internal parts of the first guide plate assembly 102 or the second guide plate assembly 103, adjusting the distance between the upper and lower flanges, and applying preload.

[0056] This design improves the overall durability and reliability of the device, makes the product surface cleaner and smoother, enhances the product's visual appeal and professionalism, and helps maintain structural integrity.

[0057] Specifically, an eighth friction part 1011 is provided on the side of the base 101 away from the bridge pier, which is used to form a bottom friction pair with the first guide plate assembly 102 or the second guide plate assembly 103.

[0058] The eighth friction part 1011, by forming a bottom surface friction pair with the first guide plate assembly 102 or the second guide plate assembly 103, can reduce direct impact and wear between components and extend the service life of the guide plate assembly and other related parts.

[0059] Preferably, the material of the eighth friction part 1011 is stainless steel.

[0060] Stainless steel materials typically possess high mechanical strength and wear resistance, enabling them to withstand large loads without easily deforming or wearing. This ensures that even during frequent relative movements, the friction pair maintains good contact surface quality, guaranteeing system stability and reliability. It significantly extends the service life of the friction pair and even the entire damper system, reducing replacement frequency and improving economic efficiency. Furthermore, high-quality stainless steel materials usually have good surface finish, which helps reduce the coefficient of friction, making the guide plate assembly slide more smoothly and reducing unnecessary energy loss. At the same time, it reduces the torque of the upper plate 301 relative to the metal damper 2 or the base 101 relative to the metal damper 2, which helps improve structural stability and reliability.

[0061] Specifically, the first guide plate assembly 102 includes two first guide plates 1021 and a first slider 1022. The cross-section of the first guide plate 1021 is inverted L-shaped, and the cross-section of the first slider 1022 is I-shaped. The two first guide plates 1021 are arranged opposite to each other on both sides of the waist plate of the first slider 1022 to guide the first slider 1022 to slide between the two first guide plates 1021.

[0062] The inverted L-shaped first guide plate 1021 and the I-shaped first slider 1022 are combined to ensure that the slider can only move in a straight line along a predetermined path, providing a high-precision guiding function and avoiding unnecessary lateral displacement or rotation. Since the waist plate of the first slider 1022 is clamped between the two first guide plates 1021, this increases the stability of the system and reduces the swaying or tilting that may occur during the sliding process.

[0063] This setup provides precise guidance and stable support, enhancing the overall reliability of the system, especially in extreme conditions such as earthquakes, helping to maintain structural integrity and protect the building's safety.

[0064] Specifically, the vertical part of the first guide plate 1021 is provided with a threaded hole in the vertical direction for connecting the first guide plate 1021 and the base 101.

[0065] The threaded holes and fasteners in the vertical direction can effectively prevent the first guide plate 1021 from slipping unnecessarily on the horizontal plane, especially under lateral force, thus maintaining the stability and reliability of the system.

[0066] The well-designed threaded hole layout can hide the bolt head, making the product surface cleaner and smoother, enhancing the product's visual appeal and professionalism. The threaded connection method is simple, intuitive, and easy to operate, requiring no complicated tools or special skills, which can speed up installation and improve work efficiency.

[0067] Specifically, the first slider 1022 includes a flat plate 10221 and a T-shaped plate 10222, and the web of the flat plate 10221 and the T-shaped plate 10222 are connected by bolts.

[0068] The separate design of the flat plate 10221 and the T-shaped plate 10222 allows the components to be processed separately during manufacturing, improving production efficiency and quality control, facilitating transportation and on-site assembly. The bolted connection allows for adjustment of the relative position between the flat plate 10221 and the T-shaped plate 10222, ensuring installation accuracy, and can be fine-tuned as needed to adapt to different installation conditions or correct errors. During installation, appropriate preload can be applied by tightening the bolts to ensure close contact between the flat plate 10221 and the T-shaped plate 10222, reducing gaps and improving the overall performance of the system. The flanges of the T-shaped plate 10222 can effectively distribute the pressure from the flat plate 10221 evenly to the first guide plates 1021 on both sides, avoiding local stress concentration and enhancing the durability of the structure.

[0069] The modular design and ease of maintenance of this device reduce wear and aging issues during long-term use, extending the service life of the entire damper system. The size and material selection can be flexibly adjusted according to different application scenarios to meet specific technical requirements and environmental conditions, making it widely applicable.

[0070] Preferably, high-strength bolts are selected.

[0071] Preferably, the flat plate 10221 is disposed between the two first guide plates 1021.

[0072] The plate 10221 is positioned between the two first guide plates 1021, so that the plate 10221 contacts the base 101. This facilitates the adjustment of the distance between the upper and lower flanges of the first slider 1022 and the application of preload through the through hole in the groove of the base 101. This reduces the machining difficulty of the connecting hole in the first slider 1022 and helps to improve the reliability and stability of the structure.

[0073] Specifically, the upper and lower flanges of the first slider 1022 are respectively in close contact with the upper and lower surfaces of the horizontal parts of the two first guide plates 1021.

[0074] The upper and lower flanges of the first slider 1022 are respectively in close contact with the horizontal parts of the two first guide plates 1021 to ensure that the slider can only move in a straight line along a predetermined path, providing a high-precision guiding function, avoiding unnecessary lateral displacement or rotation, so that the horizontal part of the guide plate can effectively transmit and disperse the pressure from the slider, enhance the structural strength of the entire guide assembly, and enable it to withstand greater loads without easily deforming.

[0075] The close contact between the flange and the horizontal section enhances the structural stability of the system, provides additional safety against external impacts, and prevents the slider from detaching from the track, especially under extreme conditions.

[0076] Specifically, the first friction part 10211, the second friction part 10212, and the third friction part 10213 are respectively provided on the upper and lower sides of the horizontal part of the first guide plate 1021 and on the side of the vertical part adjacent to the plate 10221.

[0077] A well-designed friction pair can reduce direct impact and wear between components, extending the service life of the guide plate assembly and other related parts. Although it increases design complexity, in the long run, due to its good durability and ease of maintenance, it actually reduces operating costs and improves economic efficiency. The design of multiple friction points makes the friction force more evenly distributed across the entire contact surface, avoiding local stress concentration, thereby improving the durability and reliability of the system.

[0078] Preferably, the first friction part 10211, the second friction part 10212 and the third friction part 10213 are all made of stainless steel, and the first friction part 10211, the second friction part 10212 and the third friction part 10213 are welded to the first guide plate 1021.

[0079] The superior properties of stainless steel and the reliability of welded connections reduce wear between components, extend the service life of friction parts and other related components, and lower maintenance costs. The robust connection method and good corrosion resistance increase the overall safety performance of the system, especially in extreme conditions such as earthquakes, helping to maintain structural integrity and protect the safety of buildings.

[0080] Specifically, a fourth friction part 10223, a fifth friction part 10224, and a sixth friction part 10225 are respectively provided between the plate 10221 and the base 101, between the plate 10221 and the vertical part of the first guide plate 1021, and between the plate 10221 and the horizontal part of the first guide plate 1021.

[0081] The fourth friction part 10223, disposed between the base 101, provides frictional force in the vertical direction to prevent unnecessary movement of the slider in the vertical direction and help disperse pressure from above. The fifth friction part 10224, disposed between the vertical part, provides lateral constraint to prevent unnecessary lateral sliding of the slider in the horizontal plane and increases the lateral stability of the system. The sixth friction part 10225, disposed between the horizontal part, provides frictional force in the horizontal direction to ensure that the slider slides along a predetermined path, while absorbing and dispersing external forces in the horizontal direction, transmitting and dispersing pressure from the flange of the T-plate 10222, enhancing the structural strength of the entire guide assembly, enabling it to withstand greater loads without easily deforming.

[0082] By selecting appropriate friction materials, this setup can maintain the coefficient of friction of each part within a reasonable range, ensuring smooth sliding while providing the necessary friction to maintain stability. This reduces direct impact and wear between components, extends the service life of the guide plate assembly and other related parts, and lowers maintenance costs.

[0083] Specifically, a seventh friction part 10226 is provided on the side of the flange of the T-shaped plate 10222 adjacent to the horizontal part of the first guide plate 1021, for forming a top surface friction pair with the first friction part 10211.

[0084] The seventh friction part 10226 and the first friction part 10211 form a top surface friction pair, which can increase the lateral stability of the system and reduce swaying or tilting during the sliding process.

[0085] Stable friction pair increases system stability, reduces potential wobbling or tilting of the slider during sliding, ensures consistency and accuracy of motion, and effectively transmits and disperses pressure from the T-plate 10222 flange, enhancing the structural strength of the entire guide assembly and enabling it to withstand greater loads without easily deforming.

[0086] The well-designed friction pair reduces direct impact and wear between components, extends the service life of the guide plate assembly and other related parts, and reduces maintenance costs. The top surface friction pair makes the friction force more evenly distributed across the entire contact surface, avoiding local stress concentration, thereby improving the durability and reliability of the system.

[0087] Preferably, the fourth friction part 10223, the fifth friction part 10224, the sixth friction part 10225 and the seventh friction part 10226 are non-metallic plates. The fourth friction part 10223, the fifth friction part 10224 and the sixth friction part 10225 are embedded in the groove on the flat plate 10221, and the seventh friction part 10226 is embedded in the groove on the T-shaped plate 10222.

[0088] The fourth friction part 10223 is disposed between the friction part and the base 101, providing vertical friction to prevent unnecessary vertical movement of the slider and help disperse pressure from above. The fifth friction part 10224 is disposed between the friction part and the vertical part, providing lateral constraint to prevent unnecessary lateral sliding of the slider in the horizontal plane and increasing the lateral stability of the system. The sixth friction part 10225 is disposed between the friction part and the horizontal part, providing horizontal friction to ensure that the slider slides along a predetermined path and absorbs and disperses external forces in the horizontal direction. The seventh friction part 10226 is disposed with the first friction part 10211 to form a top surface friction pair, providing top surface friction to ensure that the T-plate 10222 slides along a predetermined path and absorbs and reduces vibrations caused by external forces, thus playing a certain role in energy dissipation.

[0089] Non-metallic materials typically have a low coefficient of friction, which reduces frictional resistance, making the slider slide more smoothly and reducing energy loss. They also possess good vibration damping properties, absorbing and reducing vibrations caused by external forces through appropriate frictional engagement, thus dissipating energy and further improving the system's energy efficiency. The design of the friction components embedded in grooves simplifies the installation process and facilitates subsequent inspection and maintenance, as the functions of each component are clearly defined and easy to disassemble and replace.

[0090] The recessed design not only simplifies the installation process but also ensures tight contact between the friction element and the slider and guide plate, reducing gaps and improving the overall system performance. Furthermore, the recessed design protects the friction element from external environmental influences, extending its service life.

[0091] The low coefficient of friction and good wear resistance of the non-metallic materials reduce wear between components, extend the service life of the friction parts and other related parts, and reduce maintenance costs. The friction pair makes the friction force more evenly distributed across the entire contact surface, avoiding local stress concentration, thereby improving the durability and reliability of the system.

[0092] Specifically, the metal damper 2 is a rolling deformation energy dissipation metal damper, and the metal damper 2 can be one or more of U-type, C-type and V-type dampers.

[0093] Rolling deformation energy-dissipating metal dampers 2 can deform and dissipate energy in one direction within the horizontal plane, adapting to the action of seismic waves or other external forces. These dampers absorb and reduce vibrations caused by external forces by converting mechanical energy into heat energy and dissipating it, thus playing a certain role in energy dissipation, effectively reducing the energy transmitted to the building structure, and improving the safety and stability of the building.

[0094] U-shaped dampers dissipate energy through bending deformation, suitable for large deformations, and effectively absorb and dissipate significant amounts of energy. C-shaped dampers dissipate energy through shear deformation, suitable for medium deformations, and provide stable energy dissipation performance over a wide frequency range. V-shaped dampers dissipate energy through tensile and compressive deformation, suitable for smaller deformations, and provide efficient energy dissipation under high-frequency vibrations. The compact design of U-shaped, C-shaped, and V-shaped dampers allows for efficient energy dissipation within limited spaces, making them particularly suitable for applications with strict installation space requirements.

[0095] This setup achieves the conversion from unidirectional energy dissipation to multidirectional energy dissipation by orthogonally coupling two or more unidirectional energy dissipation metal dampers 2 with a metal damping coupling motion bracket, thus solving the problem that traditional unidirectional energy dissipation dampers can only dissipate energy in one direction.

[0096] Specifically, the metal damper 2 is connected to the T-plate 10222 via the connector 4 and the pressure plate 5.

[0097] The T-shaped plate 10222 is connected to the metal damper 2, which avoids motion interference between the metal damper 2 and the first guide plate 1021 when the metal damper 2 is rolling and deforming. This ensures that the metal damper 2 is relatively displaced from the first guide plate 1021 while rolling and deforming, without affecting its energy dissipation performance.

[0098] Preferably, connector 4 is a clamping bolt.

[0099] Specifically, the first guide plate assembly 102 also includes a limiting block 1023 for limiting the first slider 1022 from exceeding the design range.

[0100] The limit stop 1023 sets the maximum displacement range of the first slider 1022, ensuring that the first slider 1022 does not exceed the predetermined working range, thereby protecting the system from excessive deformation or damage and reducing the risk of the slider detaching from the track. Especially in extreme cases, such as earthquakes, it helps maintain structural integrity and protects the safety of the building. The presence of the limit stop 1023 ensures the motion accuracy and response consistency of the system, prevents unexpected behavior caused by the first slider 1022 exceeding the working range, and improves the overall performance of the system. When the first slider 1022 approaches its limit position, the limit stop 1023 can help absorb and disperse the remaining energy, playing a certain role in energy dissipation and further improving the energy consumption capacity of the system.

[0101] The limit stop 1023 should be made of high-strength, wear-resistant materials, such as stainless steel or special alloys, to ensure its long-term stable performance. For applications requiring vibration damping, elastic materials can also be considered as a buffer layer to further improve the system's safety and durability.

[0102] The precise displacement control and reliable limit mechanism improve the overall reliability of the system and ensure long-term stable operation. By preventing overload damage and reducing unnecessary wear, it extends the service life of sliders, guide plates and other related parts, reduces maintenance costs, and the reasonably set limit blocks can achieve efficient limit function in limited space, making it particularly suitable for application scenarios with strict requirements on installation space.

[0103] Longitudinal Deformation: During damped longitudinal deformation, the upper seat plate 301 pushes the third guide plate assembly 302, which moves longitudinally relative to the first guide plate assembly 102. This drives the first metal damper 201 to roll and deform on the top surfaces of the first guide plate assembly 102 and the third guide plate assembly 302, thus achieving energy dissipation through longitudinal deformation. Since the second metal damper 202 can slide on the second guide plate assembly 103 and the fourth guide plate assembly 303, and longitudinal limiting blocks are provided on the second guide plate assembly 103 and the fourth guide plate assembly 303, and sufficient clearance is provided between the second guide plate assembly 103 and the fourth guide plate assembly 303, the second metal damper 202 installed on the second guide plate assembly 103 and the fourth guide plate assembly 303 will not undergo plastic deformation.

[0104] Lateral Deformation: During damped lateral deformation, the upper seat plate 301 pushes the fourth guide plate assembly 303 to move laterally. The fourth guide plate assembly 303 moves laterally relative to the second guide plate assembly 103, thereby driving the second metal damper 202 to roll and deform on the top surfaces of the second guide plate assembly 103 and the fourth guide plate assembly 303, achieving energy dissipation through lateral deformation. Since the first metal damper 201 can move within the first guide plate assembly 102 and the third guide plate assembly 302, the first metal damper 201 installed on the first guide plate assembly 102 and the third guide plate assembly 302 will not undergo plastic deformation.

[0105] When the device deforms at any other angle within the plane: When the entire device deforms along an angle A within the plane, both the first metal damper 201, which dissipates energy longitudinally, and the second metal damper 202, which dissipates energy laterally, will deform along direction A. However, due to the presence of the encircling guide plate and the I-shaped slider, the deformation of the two dampers is decomposed into two orthogonal horizontal movements: one is the movement in the energy dissipation direction, and the other is the movement in the automatic movement direction. Taking the deformation of the second metal damper 202 in the lateral direction as an example, the second metal damper 202 will roll and deform laterally on the top surface of the second guide plate assembly 103 and the fourth guide plate assembly 303 to dissipate energy, and slide freely longitudinally within the encircling guide plate. The second guide plate assembly 103 and the fourth guide plate assembly 303 are designed with lateral limiting blocks at the front and rear longitudinally inside, and the second guide plate assembly 103 and the fourth guide plate assembly 303 have sufficient clearance for movement, which ensures the required displacement for movement and prevents the damper position from exceeding the length of the guide plate. Two dampers with orthogonal energy dissipation directions can achieve energy dissipation under arbitrary angle deformation by coupling through a motion coupling bracket.
