Description

Technical Field

[0001] The present application relates to the field of modular prefabricated building installation, and in particular to a supporting connection structure for modular buildings. Background Art

[0002] With the rapid development of the construction industry, modular construction has attracted widespread attention due to its efficiency and flexibility. Modular construction, also known as modular building, involves breaking down a building into independent modules. The modules are then completed in a factory, including structural design, decoration, plumbing, and equipment piping. These modules are then transported to the site and quickly assembled into a complete building using reliable connection technology.

[0003] During the assembly process, modular buildings require a stable foundation to enhance the overall stability and durability of the structure. For example, multiple pile foundation columns can be installed at predetermined locations, and the modular building can be assembled on these pile foundation columns, which can stably support the weight of the modular building.

[0004] However, because modular buildings have relatively fixed load-bearing nodes at their bases and the pile foundation columns are also located in relatively fixed positions, the assembly of modular buildings requires precise alignment and connection of the load-bearing nodes and pile foundation columns. However, the large size and weight of modular buildings make the alignment and installation of the load-bearing nodes and pile foundation columns difficult, thus affecting the efficiency of modular building assembly. Utility Model Content

[0005] The purpose of the present application is to provide a supporting connection structure for modular buildings, aiming to solve the problem that the alignment installation operation between the bearing nodes and pile foundation columns of modular buildings affects the splicing and installation efficiency.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] Some embodiments of the present application provide a supporting connection structure for a modular building, the supporting connection structure comprising a module body, a plurality of supporting seats, and a plurality of limiting members. The module body is provided with a plurality of supporting nodes, and the supporting seats are supported and connected to the supporting nodes of the module body. The limiting members and the supporting nodes are located on the same side of the module body, and the limiting members are connected to the module body near the supporting nodes for positioning and installing the supporting seats and the supporting nodes. In some embodiments, the supporting seats are installed with the supporting nodes along a first straight line direction. Along the first straight line direction, the installation gap between the supporting nodes and the supporting seats is smaller than the height dimension of the limiting members.

[0008] In some embodiments, the supporting connection structure further includes a plurality of pads, one pad is mounted on an end of the limiting member away from the module body along a first straight line direction, and the pad is disposed on an inner side of the supporting seat of the limiting member.

[0009] In some embodiments, at some support nodes, a plurality of position-limiting members are spaced apart and distributed around the support nodes.

[0010] In some embodiments, at a support node, three limiting members are distributed around the support node at intervals of 120°.

[0011] Alternatively, at one support node, four limiting members are distributed around the support node at intervals of 90°.

[0012] In some embodiments, the module body is a prefabricated steel structure.

[0013] And / or, the limiting component is a metal component.

[0014] And / or, the support seat is a metal component or a reinforced concrete component.

[0015] In some embodiments, the supporting connection structure further includes a plurality of elastic supporting members, the supporting seat is installed along the first straight line direction with the supporting node, and an elastic supporting member is fixedly connected between a supporting seat and a supporting member along the first straight line direction.

[0016] In some embodiments, the elastic support member includes a first pressure plate, a second pressure plate, an elastic member, and a slide member. The first pressure plate is fixedly connected to the module body at the support node, and the second pressure plate is fixedly connected to the support seat. The elastic member is mounted between the first pressure plate and the second pressure plate along a first linear direction. The slide member is mounted between the first pressure plate and the elastic member along a first linear direction perpendicular to the direction of the translational displacement and is configured to release the translational displacement between the first pressure plate and the elastic member.

[0017] In some embodiments, the elastic member includes a first elastic block and a second elastic block. One end of the first elastic block is mounted in contact with the slide member along a first linear direction, and the other end of the first elastic block is provided with a first spherical surface. One end of the second elastic block is connected to the second pressure plate along the first linear direction, and the other end of the second elastic block is provided with a second spherical surface. One of the first and second spherical surfaces is concave, and the other is convex. The first elastic block is supported on the second spherical surface of the second elastic block via the first spherical surface.

[0018] In some embodiments, a lubricant is filled between the first spherical surface and the second spherical surface.

[0019] Alternatively, a drag reducing coating is provided on at least one of the first spherical surface and the second spherical surface.

[0020] Since the module body is provided with a plurality of limiting members on the same side of the supporting node, the limiting members can be connected to the module body near the supporting node. For example, the limiting member can be a block structure, and one or more limiting members are arranged at circumferential intervals around a supporting node. The limiting member can also be provided with a ring structure or a frame structure so that the supporting node is located on the inner side of the limiting member. In this way, in the process of splicing and installing the module body, the limiting members protruding downward and the supporting seats protruding upward are provided so that the multiple supporting nodes of the module body can be accurately aligned and plugged in with the multiple supporting seats. That is, by providing a plurality of limiting members as the positioning structure between the supporting seat and the supporting node, it is ensured that the module body can be quickly and accurately plugged in during the splicing and installation process. The structure is simple and the positioning and installation operation process of the supporting node and the supporting seat is simplified, thereby improving the splicing and installation construction efficiency of the module body.

[0040] See Figure 1 , Figure 1 A schematic diagram of a supporting connection structure of a modular building provided in an embodiment of the present application. The present application provides a supporting connection structure of a modular building, hereinafter referred to as supporting connection structure 100. The supporting connection structure 100 includes a module body 10, a plurality of supporting seats 20 and a plurality of limiting members 30. Figure 2 , Figure 2 for Figure 1 A partial enlarged schematic diagram of point A in the middle. The module body 10 is provided with multiple support nodes 11, and the support base 20 is supported and connected to the support nodes 11 of the module body 10. The limiting member 30 is located on the same side of the module body 10 as the support nodes 11, and the limiting member 30 is connected to the module body 10 near the support nodes 11, which is used to position and install the support base 20 and the support nodes 11.

[0041] The support base 20 can be a pile foundation column or multiple supporting structures pre-installed on a building foundation. The provision of multiple support bases 20 provides a stable support for the module body 10 while facilitating flexible adjustment of the flatness of the module body 10 during installation. It should be noted that the support base 20 can be a metal component or a reinforced concrete component, without limitation.

[0042] The multiple support nodes 11 of the module body 10 are generally located at the intersection of multiple shear walls, multiple deck beams, the intersection of deck beams and shear walls, or below the column structure. This allows the overall weight of the module body 10 to be concentrated at the multiple support nodes 11 below the intersections through the columns, multiple deck beams, and multiple shear walls, facilitating stable and effective support of the module body 10 by the multiple support bases 20. Furthermore, the intersections formed by at least one of the columns, deck beams, shear walls, and floor decking provide greater structural strength at the intersections, allowing the forces acting between the support bases 20 and the support nodes 11 to be diffused through the intersections to the overall structure of the module body 10, resulting in greater stability.

[0043] Based on this, in the embodiment of the present application, since the module body 10 is provided with multiple limiting members 30 on the same side of the support node 11, the limiting members 30 can be connected to the module body 10 near the support node 11. For example, the limiting members 30 can be a block-shaped structure, and one or more limiting members 30 are arranged at circumferential intervals around a support node 11. The limiting members 30 can also be provided with a ring structure or a frame structure so that the support node 11 is located on the inner side of the limiting members 30. In this way, during the splicing and installation of the module body 10, the limiting members 30 protruding downward and the support seats 20 protruding upward are provided so that the multiple support nodes 11 of the module body 10 can be accurately aligned and plugged into the multiple support seats 20. That is, by providing multiple limiting members 30 as a positioning structure between the support seats 20 and the support nodes 11, it is ensured that the module body 10 can be quickly and accurately plugged into place during the splicing and installation process. The structure is simple and the positioning and installation operation process of the support nodes 11 and the support seats 20 is simplified, thereby improving the splicing and installation construction efficiency of the module body 10.

[0044] In some embodiments, as Figure 2 As shown, the support base 20 is installed with the support node 11 along the first straight line direction (ie, the Y direction) as an example. Along the Y direction, the installation gap a between the support node 11 and the support base 20 is smaller than the height dimension h of the limiting member 30.

[0045] Since the installation gap between the support nodes 11 and the support seats 20 along the Y direction is smaller than the height of the limiting member 30, after the module body 10 is positioned and installed on the multiple support seats 20 through the multiple support nodes 11, the multiple limiting members 30 can limit the translation of the module body 10 in a plane perpendicular to the Y direction relative to the multiple support seats 20, which is conducive to improving the stability of the module body 10 after assembly and connection.

[0046] In addition, under severe natural disaster conditions such as earthquakes, tsunamis or mudslides, the module body 10 can effectively resist the destructive effects caused by lateral horizontal forces through the limiting effect of multiple limiting members 30 and multiple support seats 20 in a plane perpendicular to the Y direction, further increasing the overall stability and disaster resistance and earthquake resistance of the modular building, and having better bearing capacity.

[0047] Based on this, Figure 2 As shown, the supporting connection structure 100 further includes a plurality of pads 40. One pad 40 is mounted on an end of the limiting member 30 away from the module body 10 along the Y direction, and is disposed on the inner side of the supporting base 20 close to the limiting member 30.

[0048] By setting the pad 40, when the module body 10 has a translational displacement relative to the support base 20, the limiting member 30 contacts the support base 20 through the pad 40. By setting different structures of the pad 40, the pad 40 can have different functional effects. For example:

[0049] The backing plate 40 can have a high structural strength. If the limiting member 30 is a steel or metal structure, by placing a backing plate 40 of a certain thickness and higher structural strength inside, the inner side of the limiting member 30 has a higher structural thickness, thereby improving the structural strength of the inner side of the lower end of the limiting member 30 and preventing positioning errors caused by deformation. Furthermore, the high structural strength of the limiting member 30 helps increase the overall stability and disaster and earthquake resistance of the modular building.

[0050] If the limiting member 30 is a reinforced concrete structure, a backing plate 40 of higher structural strength (such as a steel plate) is provided on the inner side of the lower end of the limiting member 30. When the limiting member 30 contacts the support seat 20 through the backing plate 40, the force exerted by the support seat 20 on the limiting member 30 can be dispersed to the load-bearing surface or multiple load-bearing points of the limiting member 30 through the backing plate 40, thereby preventing structural damage caused by excessive local stress on the reinforced concrete surface.

[0051] Alternatively, the backing plate 40 can be configured as a flexible structure, such as a flexible or elastic structure such as rubber or a metal with a honeycomb structure. In this way, when the limiting member 30 contacts the support base 20 through the backing plate 40, the force applied by the support base 20 to the limiting member 30 can be buffered and absorbed by the backing plate 40. Thus, the provision of the backing plate 40 with a buffering structure can prevent the support base 20 and the limiting member 30 from being damaged by the large force during direct contact.

[0052] In some other embodiments, the above-mentioned buffer structure or the high structural strength pad 40 can also be arranged on the peripheral side of the upper end of the support seat 20, which can also achieve the effect of structural protection.

[0053] In some embodiments, as Figure 3 and Figure 4 As shown, Figure 3 for Figure 2 A first bottom view of the module body 10 at the support node 11 is shown in FIG. Figure 4 for Figure 2 FIG. 1 shows a second bottom view of the module body 10 at a support node 11 . At one support node 11 , a plurality of position limiting members 30 are spaced apart and distributed around the support node 11 .

[0054] For example, Figure 3 As shown, at one support node 11, the number of the limiting members 30 may be four, and the four limiting members 30 are distributed around the support node 11 at intervals of 90°. Figure 4 As shown, at one support node 11 , there may be three position-limiting members 30 , and the three position-limiting members 30 are distributed around the support node 11 at intervals of 120°, so that the position-limiting members 30 are fixedly connected to the module body 10 .

[0055] Alternatively, at a support node 11, there may be two position-limiting members 30, with the two position-limiting members 30 spaced 180° apart around the support node 11. Alternatively, five position-limiting members 30 may be provided at a support node 11, with the five position-limiting members 30 spaced 72° apart around the support node 11. Similarly, multiple position-limiting members 30 may be spaced and evenly distributed around the support node 11.

[0056] Alternatively, the spacing angle between two adjacent limiting members 30 can be flexibly adjusted according to actual needs. It is only necessary to make the spacing size between two circumferentially adjacent limiting members 30 smaller than the size of the support seat 20 to avoid the situation where a certain support seat 20 is separated from the support node 11 due to the gap between two adjacent limiting members 30 during the translational displacement of the module body 10.

[0057] It should be noted that in the embodiment of the present application, among the multiple limiting members 30 that are evenly distributed at preset angles around the support node 11, due to the existence of processing errors and installation errors, within the error range of -5° to 5°, the multiple limiting members 30 can be regarded as being circumferentially spaced and evenly distributed.

[0058] In the above Figure 3 and Figure 4In the illustrated embodiment, the limiting members 30 can be configured as a block structure. Multiple limiting members 30 are spaced apart around the support node 11 to accurately locate the mounting position of the support base 20 and the support node 11, thereby facilitating the simultaneous positioning and installation of both. After the support base 20 and the support node 11 are accurately aligned, the gaps between the spaced limiting members 30 facilitate the connection and installation operation between the support base 20 and the support node 11.

[0059] In some other embodiments, the limiting member 30 may also be configured to be a ring-shaped structure or a frame-shaped structure, so that the supporting node 11 is located inside the limiting member 30 .

[0060] For example, the limiting member 30 may be a circular ring structure or an elliptical ring structure. The limiting member 30 may be installed around a supporting node 11 and fixedly connected to the module body 10 , with the supporting node 11 located inside the limiting member 30 .

[0061] Alternatively, the limiting member 30 may be a frame structure such as a triangular frame, a rectangular frame, a pentagonal frame, or a hexagonal frame. After the limiting member 30 is installed around a supporting node 11 and fixedly connected to the module body 10, the supporting node 11 is located inside the limiting member 30.

[0062] In this way, since the above-mentioned ring-shaped or frame-shaped limiting member 30 has an appropriate height dimension in the Y direction, while facilitating the accurate positioning of the support seat 20 and the support node 11, the ring-shaped or frame-shaped limiting member 30 can effectively limit the maximum translational displacement between the module body 10 and the support seat 20 in a 360° all-round space.

[0063] Based on this, Figure 5 As shown, Figure 5 for Figure 2 A third bottom view of the module body at the support node is shown in FIG. Multiple limiting members 30 are spaced apart around the support node 11. The limiting members 30 are arcuate sheet-like structures and are spaced apart along a concentric circle around the support node 11. For example, three limiting members 30 are spaced apart at 120° intervals along the concentric circle, or four limiting members 30 are spaced apart at 90° intervals along the concentric circle.

[0064] In this way, the spaced limiting members 30 are beneficial to the positioning and installation of the support seat 20 and the support node 11. The multiple limiting members 30 spaced along a concentric circle can also uniformly limit the translation of the inner-positioned support seat 20 in all directions of 360°, which is beneficial to improving the stability of the splicing installation of the module body 10.

[0065] It should be noted that the module body 10 as a prefabricated building structure may be a reinforced concrete structure or a steel structure or other prefabricated module with high structural strength.

[0066] In some embodiments, the module body 10 is a prefabricated steel structure. This allows the module body 10 to be disassembled into multiple parts during factory production, facilitating fabrication. These parts are then assembled together using rivets, hinges, or welding to form the module body 10. This ensures that the module body 10 possesses high tensile and compressive strength and excellent seismic performance, ensuring the structural stability and safety of the building. This also significantly increases the production speed of the module body 10.

[0067] Furthermore, for the module body 10 of the prefabricated structure, especially the module body 10 that needs to be transported over long distances, the module body 10 of the prefabricated steel structure has good stability during the long-term and long-distance operation and hoisting process, and will not suffer from cracking or damage caused by poor local maintenance.

[0068] The limiting component 30 may also be a metal component.

[0069] If the module body 10 is a prefabricated steel structure, the metal structure limiting member 30 can be fixedly installed at the corresponding position of the module body 10 by riveting or welding, etc., while ensuring the structural strength and the installation arrangement is more flexible.

[0070] If the module body 10 is a reinforced concrete structure, steel bar connection points can be provided around the support nodes 11 to facilitate fastening the limiting member 30 to the metal structure via bolts or welding. Alternatively, the limiting member 30 can be made of reinforced concrete, in which case the limiting member 30 needs to be cast and formed simultaneously with the module body 10.

[0071] Regarding the module body 10 and the support base 20, in the related technical solutions, the support base 20 is connected to the support node 11 by welding or bolts. However, the above two connection methods have many shortcomings:

[0072] As for the welding connection method, in the relevant technical solution, since the module body 10 needs to be welded and fixed to the support seat 20 of the steel structure at the support node 11. Since the part where the module body 10 is connected to the support seat 20 at the support node 11 is the node position where the beam and the column are connected, it is a stress concentration area and the requirements for welding quality are relatively high. The welding interface needs to adopt the form of full penetration welding, and it is necessary to open a cut at the top of the steel structure support seat 20. However, the top cross-section of the support seat 20 after the cut has no force-bearing area and does not play a supporting role for the module body 10. During the welding work, it is necessary to add a temporary support structure near the support seat 20, which further increases the complexity of the splicing installation.

[0073] With regard to the aforementioned bolt connection, in the related technical solution, the module body 10 needs to be bolted to the support base 20 of the steel structure at the support node 11. Since the module body 10 itself is relatively heavy, and considering the effects of environmental loads (such as wind loads, seismic loads, and temperature change loads, etc.) at the assembly site on the module body 10, the bolts used to connect the module body 10 to the support base 20 at the support node 11 need to withstand significant shear forces and bending moments, and therefore a larger number of bolts are required to share the aforementioned forces. The greater the number of bolts, the higher the installation accuracy requirements due to the alignment of the bolt holes during the splicing and installation process. Furthermore, since the module body 10 needs to align multiple bolt holes at multiple support nodes 11, the difficulty of the splicing and installation process of the module body 10 is further increased.

[0074] Moreover, in both of the above-mentioned connection forms, the connection between the module body 10 and the support seat 20 is used as a rigidly fixed connection node. The characteristic of a rigid connection node is that it constrains the force and bending moment of six degrees of freedom. Due to the long overall length of the large module, the steel structure of the bottom support node 11 and the support seat 20 are both open-air structures. When the temperature changes, the steel structure will produce temperature stress, which will cause deformation of the deck beam. The rigid connection node cannot effectively release the deformation of the steel structure caused by temperature stress, which will cause damage and destruction to the structure itself in the long run. In addition, after the module body is in place, both of the above-mentioned connection forms require a long time to complete the positioning and on-site installation and construction work, which increases the cost and construction period of the overall project delivery.

[0075] Based on this, Figure 2 As shown, the supporting connection structure 100 further includes a plurality of elastic supporting members 50. The supporting base 20 is installed with the supporting node 11 along the first linear direction (ie, the Y direction), and one elastic supporting member 50 is fixedly connected between one supporting base 20 and one supporting node 11 along the Y direction.

[0076] In this way, by installing and connecting the elastic support member 50 between the support seat 20 and the support node 11, a flexible connection between the support seat 20 and the support node 11 is achieved through the elastic structure or flexible structure of the elastic support member 50 itself, thereby avoiding the problem of excessive local stress between the support seat 20 and the support node 11 caused by the rigid connection.

[0077] Because the elastic support member 50 absorbs some of the stress between the support base 20 and the module body 10 through its own elastic deformation, it helps reduce the strength of the fixed connection between the support base 20 and the module body 10. In other words, during the process of fixing the elastic support member 50 to the support base 20 and the module body 10, the required connection strength between the support base 20 and the module body 10 can be achieved through conventional welding or the use of a relatively small number of bolts. This helps simplify the splicing and installation process of the module body 10 and reduces the overall project delivery cost and construction period.

[0078] Furthermore, since one or more limiting members 30 are installed near the supporting node 11 , the limiting members 30 limit the maximum translational displacement, thereby further increasing the stability of the connection between the module body 10 and the supporting seat 20 .

[0079] For example, since the large module body 10 is manufactured and assembled at a considerable distance from its production site, after being transported for a long distance, there is no need to temporarily install a support structure during assembly. Instead, it can be placed directly on the support base 20 at the work site (with elastic support members 50 pre-installed between them), thus requiring less stringent construction precision. Furthermore, the presence of the limiting member 30 further simplifies positioning and assembly, thereby reducing both construction difficulty and time.

[0080] Furthermore, the present invention replaces the rigid connection between the module body 10 and the support base 20 with an elastic (flexible) connection through the provision of elastic supports 50. By releasing some degrees of freedom at the connection nodes to absorb concentrated stress at the connection nodes caused by changes such as vibration and temperature, the seismic resistance and temperature suitability of large modular buildings are enhanced, improving the safety and stability of the overall structure.

[0081] In some embodiments, as Figure 6 As shown, Figure 6 for Figure 2 An exploded view of the elastic support member 50 is shown in FIG. The elastic support member 50 includes a first pressure-bearing plate 51, a second pressure-bearing plate 52, and an elastic member 53. The first pressure-bearing plate 51 is fixedly connected to the module body 10 at the support node 11, and the second pressure-bearing plate 52 is fixedly connected to the support base 20. The elastic member 53 is installed between the first pressure-bearing plate 51 and the second pressure-bearing plate 52 along a first straight line.

[0082] The elastic member 53 may be an integral component or a split component.

[0083] For example, the elastic member 53, a block-shaped structure made of a polymer material such as rubber, forms a retaining structure on the lower side of the first pressure-bearing plate 51 and the upper side of the second pressure-bearing plate 52, allowing the elastic member 53 to be squeezed and installed between the first and second pressure-bearing plates 51, 52. In this way, through the elastic deformation of the elastic member 53 in multiple directions, it can absorb concentrated stress in multiple directions between the support base 20 and the support node 11, such as vertically (e.g., in the Y direction), horizontally, and front-to-back. This effectively absorbs dynamic loads in multiple directions on the module body 10 during use, and provides flexible adjustment space for the connection and installation of the module body 10 and the support base 20.

[0084] The elastic member 53 may also be a component structure, i.e., a spring, a spring, a limiter, and other components may be used to form an elastic assembly capable of absorbing dynamic loads in at least the vertical direction. Alternatively, further components may be added to the elastic assembly to further absorb translational loads in the left-right or vertical directions. This also provides flexible adjustment space for the connection and installation of the module body 10 and the support base 20.

[0085] In some embodiments, reference Figure 2 and Figure 6 The elastic support member 50 also includes a slide member 54, which is installed between the first pressure plate 51 and the elastic member 53 along the Y direction, and is used to release the translational displacement between the first pressure plate 51 and the elastic member 53. The first straight line direction (Y direction) is perpendicular to the direction of the translational displacement (such as the X direction).

[0086] Specifically, the provision of the slide member 54 allows for relative sliding between at least one of the slide member 54 and the first pressure plate 51, or between the slide member and the elastic member 53, to further increase the maximum translational displacement of the elastic support member 50. This facilitates the elastic support member 50's ability to absorb dynamic loads in the translational direction of the module body 10. Furthermore, during the splicing and installation process, the larger translational displacement facilitates alignment of the partial support seat 20 with the support node 11.

[0087] A limiting structure may be provided between the first pressure-bearing plate 51 and the second pressure-bearing plate 52 to limit the maximum translational displacement of the first pressure-bearing plate 51 relative to the second pressure-bearing plate 52 in the X-direction. Alternatively, a plurality of limiting members 30 may be used to cooperate and limit the displacement. This prevents the elastic support 50 from being unable to stably support the module body 10 due to a large internal translational displacement.

[0088] In some embodiments, as Figure 6As shown, the elastic member 53 includes a first spring block 531 and a second spring block 532. Along the Y direction, one end (e.g., the upper end) of the first spring block 531 contacts the slide member 54, and the other end (e.g., the lower end) of the first spring block 531 is provided with a first spherical surface 533. Along the Y direction, one end (e.g., the lower end) of the second spring block 532 is connected to the second pressure-bearing plate 52, and the other end (e.g., the upper end) of the second spring block 532 is provided with a second spherical surface 534. One of the first spherical surface 533 and the second spherical surface 534 is concave, and the other is convex. The first spring block 531 is supported by the first spherical surface 533 on the second spherical surface 534 of the second spring block 532.

[0089] Based on this, by providing a first elastic block 531 and a second elastic block 532 supported and connected via a first spherical surface 533 and a second spherical surface 534, the first elastic block 531 and the second elastic block 532 can rotate relative to each other at the first spherical surface 533 and the second spherical surface 534. This allows for rotation in all directions while bearing vertical loads. This provides advantages such as a large rotation angle, flexible rotation, a rotational torque that is independent of the rotation angle, and consistent rotational performance in all directions. In other words, the provision of the elastic member 53 helps improve the module body 10's ability to absorb dynamic loads in multiple directions during use.

[0090] Among them, such as Figure 6 As shown, the first spherical surface 533 can be set as a spherical convex surface, and the second spherical surface 534 can be set as a spherical concave surface, so that the second elastic block 532 can support and wrap the first elastic block 531 through the groove structure, and has better stability.

[0091] Alternatively, the first spherical surface 533 may be a spherical concave surface, and the second spherical surface 534 may be a spherical convex surface, which can also enable the first elastic block 531 and the second elastic block 532 to be supported, connected, and relatively rotated.

[0092] In some embodiments, a lubricant is filled between the first spherical surface 533 and the second spherical surface 534. Alternatively, a drag-reducing coating is provided on at least one of the first spherical surface 533 and the second spherical surface 534.

[0093] For example, a lubricant such as grease or silicone grease can be filled between the first spherical surface 533 and the second spherical surface 534. By reducing the sliding friction between the first spring block 531 and the second spring block 532, while reducing the friction loss between the first spherical surface 533 and the second spherical surface 534, it is beneficial to further reduce the rotational torque between the first spring block 531 and the second spring block 532, so as to improve the flexibility of the elastic support 50.

[0094] Additionally, a drag-reducing coating may be provided on the first spherical surface 533. Alternatively, a drag-reducing coating may be provided on the second spherical surface 534. Furthermore, a drag-reducing coating may be provided on both the first spherical surface 533 and the second spherical surface 534. For example, the drag-reducing coating may be made of polytetrafluoroethylene or metal, which has the advantage of a low surface friction coefficient and can also reduce frictional losses between the first spherical surface 533 and the second spherical surface 534.

[0095] It should be noted that, in the embodiment of the present application, the first elastic block 531 and the second elastic block 532 may be partially or entirely configured as elastic materials such as rubber. For example, a portion of at least one of the first elastic block 531 and the second elastic block 532 may be made of elastic material or flexible material.

[0096] Alternatively, when the first spring block 531 and the second spring block 532 are supported and contacted by the first spherical surface 533 and the second spherical surface 534, the first spring block 531 and the second spring block 532 can also be set to a metal material such as steel, copper or aluminum alloy, which also facilitates flexible adjustment of the elastic support member 50.

[0097] Among them, the elastic support member 50 in the embodiment of the present application can be a spherical support seat, an aluminum alloy support seat or a durable support seat supplemented with silicone grease, etc. The product is stable and easy to install and use.

[0098] During actual application, a limiting structure is used between the first pressure plate 51 and the second pressure plate 52 of the elastic support member 50 to limit the maximum displacement of the first pressure plate 51 in multiple directions such as up and down, front and back, and left and right compared to the second pressure plate 52, as well as the maximum rotation angle of the first pressure plate 51 compared to the second pressure plate 52, so that the elastic support member 50 has better stability while meeting the load and absorbing dynamic loads.
