Description

Technical Field

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

[0002] With the rapid development of the construction industry, modular construction has attracted widespread attention due to its high efficiency and flexibility. Modular construction, also known as modular building, is a method of breaking down a building into independent modules, completing the module structure, decoration, water and electricity, equipment and pipeline construction processes in the factory, and then transporting it to the site and quickly assembling it into a whole building through reliable connection technology.

[0003] During the assembly process of modular buildings, a stable supporting foundation is required to improve the overall stability and durability of the building. For example, multiple pile foundation columns can be set at preset positions, and the modular building can be assembled on the pile foundation columns, so that the pile foundation columns can stably bear the weight of the modular building.

[0004] However, since the bottom of the modular building has a relatively fixed bearing node, and the location of the pile foundation column is also relatively fixed, in the process of assembling the modular building, the bearing nodes and the pile foundation columns need to be accurately aligned and connected one by one. However, since the modular building has a large volume and weight, the alignment and installation process of the bearing nodes and the pile foundation columns is difficult to operate, which affects the splicing and installation efficiency of the modular building. Summary of the invention

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

[0006] In order 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 installed along the first straight line direction at one end of the limiting member away from the module body, and the pad is arranged on the inner side of the supporting seat that the limiting member faces.

[0009] In some embodiments, at some support nodes, a plurality of position limiting members are spaced apart 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 a 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 also includes a plurality of elastic supporting members, the supporting seat is installed with the supporting node along the first straight line direction, 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 used to fix the module body at the support node, and the second pressure plate is used to fix the support seat. The elastic member is installed between the first pressure plate and the second pressure plate along a first straight line direction. The slide member is installed between the first pressure plate and the elastic member along a first straight line direction to release the translational displacement between the first pressure plate and the elastic member, and the first straight line direction is perpendicular to the direction of the translational displacement.

[0017] In some embodiments, the elastic member includes a first elastic block and a second elastic block. Along the first straight line direction, one end of the first elastic block is contacted and installed with the sliding plate, and the other end of the first elastic block is provided with a first spherical surface. Along the first straight line direction, one end of the second elastic block is connected and arranged with the second pressure plate, and the other end of the second elastic block is provided with a second spherical surface. One of the first spherical surface and the second spherical surface is a concave surface and the other is a convex surface, and the first elastic block is supported and arranged at the second spherical surface of the second elastic block through 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 and arranged with 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 arranged to be an annular 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 used to enable the multiple supporting nodes of the module body to be accurately aligned and plugged in and installed 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 also 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 the center A. The module body 10 is provided with a plurality of supporting nodes 11, and the supporting seat 20 is supported and connected to the supporting node 11 of the module body 10. The limiting member 30 and the supporting node 11 are located on the same side of the module body 10, and the limiting member 30 is connected to the module body 10 near the supporting node 11, and is used for positioning and installing the supporting seat 20 and the supporting node 11.

[0041] The support seat 20 can be a pile foundation column or a plurality of support structures on a preset building foundation. By setting a plurality of support seats 20, the flatness of the module body 10 can be flexibly adjusted during the installation process while stabilizing the support module body 10. It should be noted that the support seat 20 can be a metal component or a reinforced concrete component, which is not limited.

[0042] For the multiple support nodes 11 of the module body 10, the support nodes 11 are generally selected at the intersection nodes of multiple shear walls, multiple deck beam intersection nodes, intersection nodes of deck beams and shear walls, or below the column structure. This is to facilitate the overall weight of the module body 10 to be gathered at the multiple support nodes 11 below the intersection nodes through the columns, multiple deck beams and multiple shear walls, so that the module body 10 can be stably and effectively supported by multiple support seats 20. In addition, the intersection node is formed by at least one of the columns, deck beams, shear walls and floor decking, so that the intersection node has a higher structural strength, so that the force between the support seat 20 and the support node 11 can be diffused to the overall structure of the module body 10 through the intersection node, and has higher stability.

[0043] Based on this, in the embodiment of the present application, since the module body 10 is provided with a plurality of limiting members 30 on the same side of the supporting node 11, the limiting member 30 can be connected and arranged with the module body 10 near the supporting node 11. For example, the limiting member 30 can be a block structure, and one or more limiting members 30 are arranged at intervals around the circumference of a supporting node 11. The limiting member 30 can also be set to be an annular structure or a frame structure, so that the supporting node 11 is located on the inner side of the limiting member 30. In this way, in the process of splicing and installing the module body 10, the limiting member 30 protruding downward and the supporting seat 20 protruding upward are provided, so that the multiple supporting nodes 11 of the module body 10 can be accurately aligned and plugged and installed with the multiple supporting seats 20. That is, by setting a plurality of limiting members 30 as the positioning structure between the supporting seat 20 and the supporting node 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 supporting node 11 and the supporting seat 20 is simplified, thereby improving the splicing and installation construction efficiency of the module body 10.

[0044] In some embodiments, Figure 2 As shown, the support seat 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 seat 20 is smaller than the height dimension h of the limiting member 30 .

[0045] Since the installation gap between the support node 11 and the support seat 20 along the Y direction is smaller than the height dimension of the limiting member 30, after the module body 10 is positioned and installed at the multiple support seats 20 through the multiple support nodes 11. Since the setting of the multiple limiting members 30 can limit the translation of the module body 10 in the plane perpendicular to the Y direction compared with the multiple support seats 20, it is beneficial to improve 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 components 30 and multiple supporting 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 installed along the Y direction at one end of the limiting member 30 away from the module body 10, and the pad 40 is disposed on the inner side of the supporting seat 20 close to the limiting member 30.

[0048] By setting the pad 40, when the module body 10 has a translational displacement compared to the support seat 20, the limiting member 30 contacts the support seat 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 pad 40 may have a high structural strength. If the limiting member 30 is a steel structure or a metal member, a pad 40 with a certain thickness and a higher structural strength is provided on the inner side so that 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 to avoid the limiting error caused by deformation. In addition, the limiting member 30 with a higher structural strength is conducive to increasing the overall stability and disaster resistance and earthquake resistance of the modular building.

[0050] If the limiting member 30 is a reinforced concrete structure, a pad 40 with higher structural strength (such as a steel plate) is arranged 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 pad 40, the force exerted by the support seat 20 on the limiting member 30 can be dispersed to the force-bearing surface or multiple force-bearing points of the limiting member 30 through the pad 40, thereby avoiding the occurrence of structural damage due to excessive local stress on the reinforced concrete surface.

[0051] Alternatively, the pad 40 may also 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 seat 20 through the pad 40, the force exerted by the support seat 20 on the limiting member 30 can be buffered and absorbed by the pad 40. In this way, by providing the pad 40 with a buffer structure, it is possible to avoid the situation in which the supporting seat 20 and the limiting member 30 are directly in contact with each other due to a large force causing damage to the structures of both.

[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, 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 is a second bottom view of the module body 10 at the 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 arranged around the support node 11 at intervals of 90°. Figure 4 As shown, at one support node 11 , the number of the limiting members 30 may also be three, and the three limiting members 30 are distributed around the support node 11 at intervals of 120°, so that the limiting members 30 are fixedly connected to the module body 10 .

[0055] Alternatively, at one support node 11, the number of the limiting members 30 may be two, and the two limiting members 30 are arranged at an interval of 180° around the support node 11. Five limiting members 30 may also be arranged at one support node 11, and the five limiting members 30 are arranged at an interval of 72° around the support node 11. By analogy, multiple limiting members 30 are 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 in which, during the translational displacement of the module body 10, a certain support seat 20 is separated from the support node 11 due to the gap between two adjacent limiting members 30.

[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 supporting 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 member 30 can be configured as a block structure, and a plurality of limiting members 30 are spaced apart around the support node 11, so that the plurality of limiting members 30 can accurately locate the installation position of the support seat 20 and the support node 11, thereby facilitating the positioning and installation of both. After the support seat 20 and the support node 11 are accurately aligned, the gaps between the spaced apart limiting members 30 facilitate the connection and installation operation between the support seat 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 on the inner side of 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 , wherein the supporting node 11 is located inside the limiting member 30 .

[0061] Alternatively, the limiting member 30 may also be a frame structure of a triangular frame, a rectangular frame, a pentagonal frame, a hexagonal frame, etc. After the limiting member 30 is installed on the peripheral side of a supporting node 11 and the limiting member 30 is fixedly connected and installed with the module body 10, the supporting node 11 is located on the inner side of the limiting member 30.

[0062] In this way, since the above-mentioned annular structure 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 annular 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. A plurality of limiting members 30 are arranged at intervals around the support node 11. The limiting members 30 are arc-shaped sheet structures, and the plurality of limiting members 30 are arranged at intervals along a concentric circle around the support node 11. For example, three limiting members 30 are arranged at intervals of 120° along a concentric circle, or four limiting members 30 are arranged at intervals of 90° along a 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 apart 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 prefabricated module with high structural strength such as a steel structure.

[0066] In some embodiments, the module body 10 is a prefabricated steel structure. In this way, during the production process of the module body 10 in the factory, the module body 10 can be decomposed into multiple parts for easy processing and manufacturing. Subsequently, the multiple parts produced are spliced ​​together to form a module body 10 by means of rivets, hinges or welding. This allows the module body 10 to have a high tensile and compressive structural strength and excellent seismic performance to ensure the structural stability and safety of the building, and at the same time is conducive to significantly improving the production speed of the module body 10.

[0067] Moreover, 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 crack or break due to poor local maintenance.

[0068] The limiting component 30 may also be configured as 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, a connection point of the steel bar can be set around the supporting node 11 to facilitate fixing the limiting member 30 connected to the metal structure by bolts or welding. Alternatively, the limiting member 30 can also be reinforced concrete, in which case the limiting member 30 needs to be cast and formed simultaneously with the module body 10.

[0071] As for 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 disadvantages:

[0072] As for the welding connection method, in the relevant technical solution, 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 welding quality requirements are relatively high. The welding interface needs to adopt the full penetration welding form, 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 support 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] As for the above-mentioned bolt connection, in the relevant technical solution, since the module body 10 needs to be bolted to the support seat 20 of the steel structure at the support node 11. Since the module body 10 itself is relatively heavy, considering the effect of the environmental load (such as wind load, earthquake load and temperature change load, etc.) at the assembly site on the module body 10, the bolts used to connect the module body 10 with the support seat 20 at the support node 11 need to withstand a large shear force and bending moment, so more bolts need to be set to share the above-mentioned forces. The more bolts there are, the higher the installation accuracy requirements caused by the alignment of the bolt holes during the splicing and installation process, and 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 two 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 the 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. The steel structure will produce temperature stress when the temperature changes, thereby causing the deck beam to deform. The rigidly connected node cannot effectively release the deformation of the steel structure caused by temperature stress, which will cause damage to the structure itself in the long run. In addition, the above two connection forms require a long time to complete the positioning and on-site installation and construction work after the module body is in place, 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 seat 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 seat 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] Since the elastic support 50 can absorb part of the stress between the support seat 20 and the module body 10 through its own elastic deformation, it is helpful to reduce the fixed connection strength between the support seat 20 and the module body 10. That is, in the process of fixedly connecting the elastic support 50 and the support seat 20 and the elastic support 50 and the module body 10, the connection strength requirements between the support seat 20 and the module body 10 can be met by ordinary welding or using fewer bolts. It is helpful to simplify the splicing and installation process of the module body 10 and reduce the cost and construction period of the overall project delivery.

[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 far from the production and construction site and the actual assembly site, after being transported to the site over a long period of time and a long distance, there is no need to temporarily set up a support structure during the assembly process, and it can be directly placed on the support seat 20 at the work site (with an elastic support member 50 pre-installed between the two), and the construction accuracy requirement is not high. In addition, the presence of the limiting member 30 can further simplify the difficulty of positioning and assembly, which is conducive to reducing the construction difficulty and reducing the construction time.

[0080] In addition, the solution of the present application replaces the rigid connection between the module body 10 and the support seat 20 with an elastic (flexible) connection through the provision of the elastic support member 50. By releasing the degrees of freedom at some connection nodes to absorb the 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, and the safety and stability of the overall structure are improved.

[0081] In some embodiments, Figure 6 As shown, Figure 6 for Figure 2 An exploded structural diagram of the elastic support member 50 is shown in FIG. The elastic support member 50 includes a first pressure plate 51, a second pressure plate 52, and an elastic member 53. The first pressure plate 51 is used to fix the module body 10 at the support node 11, and the second pressure plate 52 is used to fix the support seat 20. The elastic member 53 is installed between the first pressure plate 51 and the second pressure plate 52 along the first straight line direction.

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

[0083] For example, the elastic block structure made of a polymer material such as rubber of the elastic member 53 forms a limiting structure on the lower side of the first pressure plate 51 and the upper side of the second pressure plate 52, so that the elastic member 53 is squeezed and installed between the first pressure plate 51 and the second pressure plate 52. In this way, through the elastic deformation of the elastic member 53 of the elastic block structure in multiple directions, the concentrated stress in multiple directions such as up and down (such as Y direction), left and right, front and back can be absorbed between the support seat 20 and the support node 11. That is, it can effectively absorb the dynamic load of the module body 10 in multiple directions during use, and provide a flexible adjustment space for the connection and installation of the module body 10 and the support seat 20.

[0084] The elastic member 53 may also be a component structure, that is, a spring, a spring sheet, a stopper and other components are used to form an elastic component capable of absorbing dynamic loads at least in the up and down directions. Alternatively, the elastic component may be further increased in components to enable the elastic component to further absorb translational loads in the left and right or up and down directions. This can also provide flexible adjustment space for the connection and installation of the module body 10 and the support seat 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] That is, by setting the sliding plate 54, at least one of the sliding plate 54 and the first pressure plate 51, or the sliding plate and the elastic member 53 can slide relative to each other to further increase the maximum translation displacement of the elastic support member 50, which is beneficial to improving the elastic support member 50 to absorb the dynamic load of the module body 10 in the translation direction. In addition, during the splicing installation process, the larger translation displacement facilitates the alignment installation of the partial support seat 20 and the support node 11.

[0087] A limiting structure may be provided between the first pressure plate 51 and the second pressure plate 52 to limit the maximum translation displacement of the first pressure plate 51 in the X direction compared with the second pressure plate 52. Alternatively, a plurality of limiting members 30 may be used to cooperate and limit the position, so as to prevent the elastic support 50 from being unable to stably support the module body 10 due to a large internal translation displacement.

[0088] In some embodiments, 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 (such as the upper end) of the first spring block 531 is in contact with the slide member 54, and the other end (such as the lower end) of the first spring block 531 is provided with a first spherical surface 533. Along the Y direction, one end (such as the lower end) of the second spring block 532 is connected to the second pressure-bearing plate 52, and the other end (such as 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 a concave surface and the other is a convex surface, and the first spring block 531 is supported on the second spherical surface 534 of the second spring block 532 through the first spherical surface 533.

[0089] Based on this, the first spring block 531 and the second spring block 532 are supported and connected via the first spherical surface 533 and the second spherical surface 534, so that the first spring block 531 and the second spring block 532 can rotate relative to each other at the first spherical surface 533 and the second spherical surface 534, that is, they can be allowed to rotate in all directions while bearing the vertical load, and have the advantages of large rotation angle, flexible rotation, rotation torque independent of rotation angle, and consistent rotation performance in all directions. That is, the arrangement of the elastic member 53 is conducive to improving the absorption capacity and absorption effect of dynamic loads in multiple directions of the module body 10 during use.

[0090] Among them, 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 rotatable.

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

[0093] Exemplarily, 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] In addition, a drag-reducing coating may be provided on the first spherical surface 533. Or a drag-reducing coating may be provided on the second spherical surface 534. A drag-reducing coating may also be provided on both the first spherical surface 533 and the second spherical surface 534. For example, the drag-reducing coating may be a coating structure made of polytetrafluoroethylene or metal, which has the advantage of a low surface friction coefficient and can also reduce the friction loss 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 is also convenient for 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 provided 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.

[0099] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
