Description

Technical Field

[0001] This application relates to the field of building materials technology, and more specifically, to a lateral limiting member and a metal component. Background Technology

[0002] Metal panels are widely used in outdoor flooring, landscape walkways, decorative wall panels, curtain wall panels, and other prefabricated building materials due to their high strength, good weather resistance, and ease of modular installation. During the paving or splicing process, adjacent metal panels usually need to be positioned and connected to maintain the stability of the splicing between the panels and the overall paving effect.

[0003] In existing technologies, adjacent metal plates are typically connected or positioned using methods such as screw fastening, snap-fit ​​connections, pressure strip clamping, or positioning components. However, during actual assembly, factors such as installation errors, operating loads, temperature changes, and the deformation of the plates themselves can cause relative displacement between adjacent metal plates, thus affecting the stability of the joint. Furthermore, some connection methods require numerous installation steps or additional fasteners, resulting in poor assembly convenience.

[0004] Therefore, how to ensure reliable splicing between two adjacent plates and reduce the possibility of relative displacement between adjacent plates has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide a lateral limiting member to ensure reliable splicing between two adjacent plates and reduce the possibility of relative displacement between adjacent plates.

[0006] Another objective of this application is to provide a metal component having the aforementioned lateral limiting member.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0017] Optionally, in the above-mentioned lateral limiting member, the limiting body is provided with a mechanical joint fixing structure, which is used to limit the width of the splicing gap between two adjacent plates.

[0018] Optionally, in the above-mentioned lateral limiting member, the mechanical joint fixing structure includes limiting steps disposed on the opposite two end faces of the limiting body, wherein there are one or more limiting steps to adapt to different splicing gap widths.

[0055] The core of this application is to provide a lateral limiting member to ensure reliable splicing between two adjacent plates and reduce the possibility of relative displacement between adjacent plates.

[0056] Another key aspect of this application is to provide a metal component having the aforementioned lateral limiting element.

[0057] The reference numerals in the accompanying drawings are merely illustrative of exemplary embodiments and are not intended to limit the scope of protection of the claims. Those skilled in the art can use equivalent alternative structures to achieve the same function.

[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] In the assembly of outdoor landscape paving, terrace paving, boardwalk paving, metal wall panel installation, decorative panel splicing, combined grid assembly, and other panel components, adjacent panels typically need to maintain a relatively stable positional relationship. In existing splicing structures, some solutions only use screws, pressure strips, edge clamps, or simple clips to vertically tighten the panels, or control the splice joint width through manual measurement and pre-planning. After installation, such structures may experience lateral movement of adjacent panels, changes in splice joint width, panel edge misalignment, localized warping, or reduced assembly precision when subjected to thermal expansion and contraction, wind loads, foot traffic, vibration, localized impacts, foundation deformation, or long-term service loads.

[0060] When adjacent panels are fixed solely by the upper clamping structure, the lateral constraint between the panels may be insufficient. Even if the clamping components can restrict the panels from lifting vertically, the panels may still tend to move relative to each other in a direction parallel to the mounting surface or the surface where the joint is located. If the joint is entirely manually installed, the width of the joint may vary at different locations; furthermore, panel movement during subsequent use may alter the original joint condition.

[0061] Therefore, such as Figure 1 As shown in the figure, this application discloses a lateral limiting member 100, including a limiting body 10. By setting the lateral limiting member 100 between two adjacent plates 201, a double-sided limiting relationship can be formed between the two plates 201, constraining the relative displacement of the adjacent plates 201, improving the stability of the splicing position, and helping to maintain the relative position of the plates 201 after assembly. It should be noted that the plate 201 is not limited to a pure metal plate; it can also be a composite plate with a metal layer, metal frame, or metal border as a load-bearing or connecting part, or a plate made of other materials, such as wood-based panels or plastic panels.

[0062] The following will combine Figures 1 to 20 The lateral limiting member 100 disclosed in the embodiments of this application will be explained and described in detail.

[0063] like Figure 20 As shown, the limiting body 10 can be disposed between two adjacent plates 201, and as... Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, limiting parts 20 can be provided on both sides of the limiting body 10, so that the limiting parts 20 on both sides can form a concave-convex fit with the corresponding plate 201 to establish a double-sided limiting relationship between the two plates 201. This can provide lateral position constraints, splice seam control and assembly connection basis between adjacent plates 201, thereby limiting the relative lateral displacement between two adjacent plates 201, which is conducive to improving the stability, installation consistency and maintenance convenience of the splicing part of the metal component 200. It should be noted that the "concave-convex fit" referred to in this application can be a fit between a protrusion, snap-fit ​​portion, elastic portion, flange, insertion portion, limiting surface or other outwardly convex structure on the limiting body 10 and a slot, cavity, groove, accommodating space, limiting wall or other inwardly concave structure on the plate 201, which can be inserted, embedded, snapped, abutted or limited. Moreover, the concave-convex fit is not limited to a complete fit in the strict sense, but can also include a fit relationship that can limit the change of relative position by elastic pre-tightening, partial abutment, surface contact, line contact or point contact under stress.

[0064] In some embodiments, such as Figures 1 to 18 As shown, the limiting body 10 can adopt a strip-shaped structure, sheet-shaped structure, profile structure, frame structure, or other connection structure suitable for being installed between adjacent plates 201, extending along a predetermined length direction. The limiting body 10 can have opposing first and second sides, with limiting parts 20 respectively disposed on the first and second sides, so that the lateral limiting member 100 can be located between two adjacent plates 201. The limiting body 10 can be an independent single-unit structure, meaning the lateral limiting member 100 can exist as an independent component when not assembled with the plate 201. It can be manufactured, transported, stored, or installed separately. This independent single-unit structure allows the lateral limiting function to be relatively independent from the main structure of the plate 201, enabling the lateral limiting member 100 to adapt to plates 201 of different specifications, splicing methods, or installation environments. Furthermore, installers can place the lateral limiting member 100 at one or more positions between adjacent plates 201 according to the splicing position, stress conditions, and installation requirements.

[0065] In some embodiments, such as Figures 1 to 18 As shown, the limiting body 10 can be a one-piece structural component, meaning that the limiting body 10, the limiting part 20, the mechanically fixed joint structure 30, the mounting groove 40, the closing structure 41, and some other structures can be integrally formed or substantially integrally formed by extrusion, stamping, bending, die casting, injection molding, machining, compression molding, or other applicable methods. When an integral structural component is used, the functional areas can have a relatively stable positional relationship, which helps to reduce positional deviations caused by assembly errors between multiple independent parts. Furthermore, lateral loads can be transmitted to the main body area of ​​the limiting body 10 through the limiting part 20, enabling the limiting body 10 to receive and disperse the forces from the two plates 201.

[0066] In some embodiments, the limiting body 10 may also be a modular assembly structure. For example, at least some of the limiting part 20, mechanical joint structure 30, mounting groove 40, and elastic damping lip 50 may be manufactured separately and then connected to the limiting body 10 by snap-fit, riveting, screwing, welding, embedding, bonding, overmolding, or other suitable connection methods. When a modular assembly structure is used, it is convenient to match different forms of limiting parts 20, mechanical joint structures 30 of different heights or positions to different plates 201, or to match external accessories 300 of different specifications. Thus, without changing the main structure of the limiting body 10, the local functional structure can be adapted or replaced.

[0067] In some embodiments, such as Figure 20As shown, a slot 2011 can be formed on the plate 201. The slot 2011 can be provided on the side, end, bottom, back, connecting edge, or other position suitable for cooperating with the lateral limiting member 100 of the plate 201. The slot 2011 can be a continuously extending groove or multiple partial grooves spaced apart along the length of the plate 201. The cross-section of the slot 2011 can be rectangular, trapezoidal, dovetail-shaped, arc-shaped, polygonal, irregular, or other structural forms that can accommodate the limiting part 20 and form a position limiting structure. The limiting part 20 can adopt a protruding structure that cooperates with the slot 2011, and the limiting part 20 can include a flange, hook, claw, insertion part, elastic locking part, limiting protrusion, limiting piece, extension arm, or other structures with lateral limiting function. When the two limiting parts 20 enter the slots 2011 of the two adjacent plates 201 respectively, if the plate 201 moves laterally toward the lateral limiting member 100, the groove wall, edge, bottom wall or other limiting area of ​​the slot 2011 can abut against the corresponding limiting part 20, thereby constraining the lateral relative displacement of the plate 201.

[0068] In some embodiments, the two limiting portions 20 may be located on opposite sides of the limiting body 10, and the two limiting portions 20 may extend in opposite directions. After assembly, the limiting portion 20 located on the first side of the limiting body 10 enters the slot 2011 of the first plate, and the limiting portion 20 located on the second side of the limiting body 10 enters the slot 2011 of the second plate 201. At this time, when the first plate tends to move laterally closer to or further away from the second plate, at least one limiting portion 20 will abut or engage with the corresponding slot 2011. By applying constraints to the two plates 201 on both sides respectively through the two limiting portions 20, the lateral limiting member 100 can form a double-sided limiting structure.

[0069] In the above embodiment, the double-sided limiting structure enables two adjacent plates 201 to establish a connection or limiting relationship with the same limiting body 10. When one of the plates 201 is subjected to force and tends to move laterally, the force it experiences can be transmitted to the limiting body 10 via the corresponding limiting part 20; the limiting body 10 can then form a reaction relationship with the other plate 201 through the other limiting part 20, thereby enabling the lateral limiting member 100 to constrain the relative displacement between adjacent plates 201.

[0070] In some embodiments, such as Figures 1 to 18As shown, the limiting portions 20 on both sides of the limiting body 10 can both adopt elastic structures. That is, when the limiting portions 20 are subjected to assembly force, lateral force, local extrusion force, or force caused by thermal expansion and contraction of the plate 201, they can generate recoverable elastic deformation within a certain range. After the external force is reduced or removed, the limiting portions 20 can return to their initial position or near the initial position under the action of their own material elasticity, structural elasticity, or a preset rebound structure. At the same time, the two limiting portions 20 are symmetrically arranged with respect to the limiting body 10. Specifically, the limiting portions 20 can be integrally extended from a local area of ​​the limiting body 10, or they can be formed by elastic components connected to the limiting body 10. The limiting portions 20 can adopt elastic plates, elastic arms, elastic claws, elastic flanges, elastic hooks, elastic tongues 21, plug-in portions with elastic deformation capabilities, or other structures that can elastically yield during assembly and form elastic abutment or elastic locking after assembly.

[0071] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, the limiting part 20 may include at least one elastic tongue 21, that is, one elastic tongue 21 may be provided on each side of the limiting body 10, or two elastic tongues 21 may be used. The elastic tongue 21 may be an elastic sheet-like part formed by partially extending, cutting, bending, stamping, or forming the limiting body 10, or it may be an elastic component independently installed on the limiting body 10. Simultaneously, the elastic tongue 21 may elastically deform along the transverse, thickness, oblique, or other directions related to the assembly force direction, so that the elastic tongue 21 can be compressed and retracted during the assembly of the plate 201 and released and rebound after assembly. Specifically, during the process of the plate 201 approaching the transverse limiting member 100 and being assembled, the entrance edge, groove wall, or guide surface of the slot 2011 can push the elastic tongue 21 to elastically deflect, compress, or bend, allowing the limiting part 20 to enter the slot 2011. After the limiting part 20 moves to the predetermined position, the elastic tongue 21 can return to the initial position or partially return under its own elastic recovery trend, so that it forms a snap, abutment or pre-tightening relationship with the slot 2011, thereby reducing the dependence on strict position alignment during the assembly process and providing a certain self-holding effect after the assembly is completed.

[0072] In some embodiments, such as Figures 1 to 18As shown, the elastic tongue 21 can extend obliquely from the limiting body 10 toward the corresponding side plate 201. Specifically, one end of the elastic tongue 21 is connected to the limiting body 10 and can serve as the root of the elastic tongue 21; the other end of the elastic tongue 21 is a free end extending toward the corresponding side plate 201, and the extension direction of the elastic tongue 21 forms a preset angle with respect to the side wall of the limiting body 10, the mounting reference surface, the insertion direction of the plate 201, the plate surface direction of the plate 201, or the groove wall direction of the slot 2011. That is, the elastic tongue 21 does not extend completely in a horizontal, vertical, or parallel direction to the side of the plate, but is set in an oblique state toward the corresponding side plate 201. It should be noted that in this embodiment, "tilting extension" can be understood as the elastic tongue 21 gradually deviating from the limiting body 10 from its root to its free end in the direction toward the plate 201. The elastic tongue 21 can tilt upwards, downwards, outwards and upwards, outwards and downwards, or in other directions that facilitate guiding, engaging, or abutting with the slot 2011 on the plate 201. The specific tilting direction of the elastic tongue 21 can be determined based on the assembly direction of the plate 201, the opening direction of the slot 2011, the installation direction of the lateral limiting member 100, and the arrangement of the external accessories 300.

[0073] In some embodiments, such as Figures 1 to 18 As shown, the inclined extension direction of the elastic tongue 21 can be adapted to the assembly entry direction of the plate 201, so that the elastic tongue 21 has a relatively gentle guide surface during the assembly process; when the plate 201 tends to detach in the opposite direction or move laterally, the elastic tongue 21 can form a blocking relationship with the plate 201 through its free end, protruding structure 211 or corresponding limiting surface, so that the inclined tongue can achieve a limiting effect that is easy to install and difficult to detach in the opposite direction to a certain extent.

[0074] In some embodiments, the tilt angle of the elastic tongue 21 can be set according to the elastic modulus of the material, the length and thickness of the elastic tongue 21, the opening size of the slot 2011, the assembly stroke, the expected clamping force, and the usage environment of the plate 201. The tilt angle should not be too small, otherwise a reliable engagement effect cannot be formed between the elastic tongue 21 and the plate 201; the tilt angle should also not be too large, otherwise it may lead to excessive assembly resistance and increased deformation of the elastic tongue 21, making it unfavorable to form a stable fit with the slot 2011. In actual design, the tilt angle, length, root position, free end position, and position of the protrusion structure 211 of the elastic tongue 21 can be adjusted to balance installation convenience, engagement stability, and elastic life.

[0075] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, a protruding structure 211 can be provided on the elastic tongue 21, and the protruding structure 211 can be a locking point, a protruding bulge, a protruding rib, a protruding tooth, a partial flange, a boss, a stop, or other protruding areas that can form a partial fit with the slot 2011. The protruding structure 211 can be provided at the free end, middle, or near the root of the elastic tongue 21, or at the connection point between the elastic tongue 21 and other limiting structures. When the protruding structure 211 enters the slot 2011, it can abut against the slot wall, inner step, limiting edge, bottom area, or other corresponding parts of the slot 2011.

[0076] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, the protruding structure 211 can be a protrusion formed by bending the elastic tongue 21 in its middle, and the protruding structure 211 can contact the edge at the entrance of the slot 2011 during the initial assembly. As the plate 201 continues to move towards the lateral limiting member 100, the edge of the slot 2011 applies a pushing force to the protruding structure 211, causing the elastic tongue 21 to deform towards the reserved space. When the protruding structure 211 passes the entrance edge of the slot 2011, the elastic tongue 21 can generate a rebound tendency, so that the protruding structure 211 is located in the inner region of the slot 2011. At this time, if the plate 201 has a reverse detachment tendency, the protruding structure 211 can abut against the entrance edge or inner limiting wall of the slot 2011, thereby hindering the reverse movement of the plate 201.

[0077] In the above embodiments, the lateral limiting member 100 possesses certain self-guiding and self-locking characteristics through the elastic snap-fit ​​process. Specifically, during installation, the elastic spring 21, the protruding structure 211, the arc transition portion 22, or the edge of the slot 2011 can collectively guide the plate 201 to move towards the predetermined assembly position. Simultaneously, after assembly, a mating relationship is formed between the limiting portion 20 and the slot 2011, preventing reverse disengagement or lateral movement. This mating relationship can be a complete snap-fit, an elastic abutment, or a limiting relationship with pre-tightening force. Furthermore, since the plate 201 may experience dimensional tolerances, installation position deviations, thermal expansion and contraction deformation, or localized stress deformation in practical applications, the elastic spring 21 allows the limiting portion 20 to adapt to different assembly states within a certain range. When there is a small positional deviation between the slot 2011 and the limiting portion 20, the elastic spring 21 can compensate through elastic deformation, thereby ensuring that the lateral limiting member 100 maintains its effective limiting function. Compared to a completely rigid plug structure, the elastic spring tongue 21 can reduce the risk of difficult assembly or excessive assembly stress caused by local dimensional deviations while ensuring the limiting function.

[0078] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, the thickness of the root of the elastic tongue 21 can be greater than the thickness of its end. That is, the dimension of the region where the elastic tongue 21 connects, transitions, or is fixed to the limiting body 10, perpendicular to the main extension surface or the main bending direction of the elastic tongue 21, can be greater than the dimension of the free end region extending away from the limiting body 10 or towards the corresponding side plate 201, perpendicular to the main extension surface or the main bending direction of the elastic tongue 21. In this embodiment, the elastic tongue 21 can be gradually thinned from the root to the end, forming a gradually changing thickness structure. This gradually changing structure can be continuous linear thinning, curved gradually thinning, stepped thinning, or segmented thinning. For example, the root of the elastic tongue 21 can have a first thickness, and the free end can have a second thickness less than the first thickness. Between the root and the end, the thickness of the elastic tongue 21 can gradually decrease, or it can first maintain a relatively constant thickness before thinning.

[0079] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, the root of the elastic tongue 21 is integrally connected to the limiting body 10. The thickness of the root region can be achieved by local thickening, reinforcing ribs, bending and overlapping, material accumulation, or forming a larger cross-section. The end region can maintain a thin elastic sheet structure, and a protrusion structure 211 can be provided at or near the end to form a snap-fit ​​or abutment relationship with the slot 2011 on the plate 201.

[0080] In the above embodiment, by adopting a structure with a thickened root and thinned ends, the elastic tongue 21 can have different bending stiffnesses along its length. When the elastic tongue 21 is subjected to the force of the plate 201 during assembly or use, its root region will bear a larger bending moment and stress transmission; the end region is mainly used for contacting, guiding, engaging, or generating corresponding elastic displacement with the slot 2011. By making the root thickness greater than the end thickness, the root can have relatively high structural strength and bending resistance, while the end maintains relatively good elastic deformation capacity. Specifically, when the plate 201 is installed, the entrance edge, groove wall, or other corresponding structure of the slot 2011 will act on the end of the elastic tongue 21 or the protrusion structure 211, causing the elastic tongue 21 to bend or retract in the direction of the deformation space 23. In this process, the force is gradually transmitted from the end to the root. Because the root is relatively thick, it can withstand a large bending load and stably transmit the force to the limiting body 10. Because the end is relatively thin, the end is more likely to undergo elastic deflection under the action of assembly force, so that the elastic tongue 21 can meet the assembly clearance requirements while avoiding excessive deformation or local damage to the root due to repeated bending.

[0081] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, a rounded transition portion 22 can be provided between the elastic spring 21 and the limiting body 10. This rounded transition portion 22 can be located at the root of the elastic spring 21, between the elastic spring 21 and the protruding structure 211, or in other stress-transfer areas between the limiting portion 20 and the limiting body 10. The rounded transition portion 22 can be an arc surface, curved surface, rounded corner, rounded structure, gradient curve structure, or other non-sharp transition structure. When the elastic spring 21 is repeatedly subjected to force during installation or use, its root is typically the area bearing bending or tensile / compressive stress. By providing the rounded transition portion 22, stress can be transferred more smoothly between the elastic spring 21 and the limiting body 10, reducing local stress concentration caused by sharp corners, right angles, or abrupt changes in cross-section. This helps improve the structural stability of the elastic spring 21 under repeated assembly, disassembly, or cyclic loading, and helps maintain its elastic recovery capability.

[0082] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14As shown, the limiting body 10 can form a deformation space 23 with the elastic tongue 21, and the deformation space 23 can be a through hole, a slot, a cavity, a recessed area, a hollow area, or a partial clearance structure. The deformation space 23 can be located on the inner side, lower side, upper side, or side corresponding to the deflection direction of the elastic tongue 21, so that the elastic tongue 21 can be displaced in the direction of the deformation space 23 when subjected to external force, thereby avoiding rigid interference between the elastic tongue 21 and the main body of the limiting body 10.

[0083] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, two elastic tongues 21 can be used, and the two elastic tongues 21 are symmetrically distributed on one side of the limiting body 10. That is, two elastic tongues 21 can be symmetrically arranged on each side of the limiting body 10. At the same time, a deformation space 23 can be formed between the two elastic tongues 21 for the elastic tongues 21 to undergo elastic deformation, so that the two elastic tongues 21 can be displaced in the direction of the deformation space 23 when subjected to external force, thereby avoiding rigid interference between the elastic tongues 21 and the main body of the limiting body 10. In addition, by symmetrically arranging two elastic tongues 21 on each side of the limiting body 10, the protrusion structure 211 of the two elastic tongues 21 can be locked in the slot 2011 of the plate 201, ensuring the reliability of the connection between the transverse limiting member 100 and the plate 201.

[0084] In the above embodiments, by providing the deformation space 23, not only is the necessary deformation stroke provided for the elastic tongue 21, but the elastic tongue 21 also has a more suitable deformation space during its entry into the slot 2011. When the slot 2011 of the plate 201 pushes the protruding structure 211, the elastic tongue 21 can generate elastic deflection with relatively small assembly resistance; after assembly, the deformation space 23 will not hinder the elastic tongue 21 from returning to the snap-fit ​​position, thus balancing installation convenience and fit stability.

[0085] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14As shown, a mechanical jointing structure 30 can be provided on the limiting body 10 to limit or control the distance between adjacent plates 201, thereby forming a predetermined splicing seam between adjacent plates 201. The mechanical jointing structure 30 can be located in the central region of the limiting body 10, or near the two side limiting portions 20. The mechanical jointing structure 30 can extend continuously along the length of the limiting body 10, or it can consist of multiple locally spaced jointing units arranged at intervals along the length direction.

[0086] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, the mechanical joint-fixing structure 30 may include limiting steps 31 disposed on opposite end faces of the limiting body 10. Two limiting steps 31 may be used, and each limiting step 31 may be located on one of the two end faces of the limiting body 10 adjacent to the plate 200. The limiting steps 31 may be formed by bosses, shoulders, walls, stepped surfaces, protruding edges, thickened portions, or height difference structures on the limiting body 10. The limiting steps 31 can abut against the splicing end face of the plate 201, the edge of the slot 2011, or other corresponding areas. During assembly, the first plate and the second plate can move towards the transverse limiting member 100 until the splicing end face of the plate 201 abuts against the limiting steps 31. At this point, the gap between the inner walls of the limiting steps 31 forms the splicing seam between the first and second plates, thus allowing the mechanical joint-fixing structure 30 to control the splicing seam. Compared to methods that rely entirely on manual measurement, observation, or temporary on-site padding, the limiting step 31 provides a clear physical limiting reference, resulting in better repeatability and consistency of the splice width.

[0087] In the above embodiment, when adjacent plates 201 are assembled, the splicing end of the plate 201 approaches the lateral limiting member 100; after it contacts the limiting step 31, the travel of the plate 201 towards the other plate 201 is blocked by the limiting step 31. Since both plates 201 can be positioned by their respective corresponding limiting steps 31, the splicing interval between the two plates 201 no longer depends entirely on the subjective judgment of the installer, but is limited by the physical structure on the lateral limiting member 100. When multiple lateral limiting members 100 are arranged at intervals along the splicing seam, multiple mechanical joint fixing structures 30 can jointly constrain the splicing relationship of the plates at different positions, thereby helping to reduce the risk of the splicing seam being locally too wide, locally too narrow, or unevenly varied along the length direction.

[0088] In some embodiments, the limiting step 31 may include one or more limiting steps 31 at different positions or different heights, and different limiting steps 31 may correspond to different installation positions of the plate 201, different splicing requirements, or different installation states of the external accessories 300. During installation, the plate 201 may be selected to abut against one of the limiting steps 31, or different types of plates 201 may be matched with limiting steps 31 at different positions. Multiple limiting steps 31 are not limited to being used simultaneously; one or more may be selected and combined according to actual structural requirements.

[0089] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, when the mechanical joint-setting structure 30 and the limiting part 20 are jointly provided, the limiting part 20 can restrict the relative movement of the plate 201 in the lateral direction, and the mechanical joint-setting structure 30 can limit the initial interval between adjacent plates 201 when they are assembled in place. Specifically, the limiting step 31 can make the plate reach the predetermined position during installation; the concave-convex fit between the limiting part 20 and the slot 2011 can suppress the plate from deviating from the predetermined position after the plate is assembled in place, thereby improving the consistency of the initial installation position and helping to maintain the relative positional stability during use.

[0090] In some embodiments, such as Figure 13 and Figure 14 As shown, a mounting groove 40 may be provided in the middle of the limiting body 10, and the mounting groove 40 can be inserted and mated with the external accessory 300. The mounting groove 40 may extend along the length of the limiting body 10, or may be formed in a partial area of ​​the limiting body 10. The mounting groove 40 may be an open groove, a semi-closed groove, a closed groove, a dovetail groove, a trapezoidal groove, a T-shaped groove, an undercut groove, an arc-shaped groove, or other groove structures capable of accommodating the external accessory 300 and limiting its movement. Meanwhile, as... Figure 19 and Figure 20As shown, the external accessory 300 can be a decorative piece, a finishing piece, a hanging piece, a fixing seat, a keel connector, a positioning piece, or other components that need to be installed in conjunction with the lateral limiting member 100. The external accessory 300 can have a plug-in portion, a snap-fit ​​portion, a sliding portion, or a connecting portion adapted to the mounting groove 40, so that the external accessory 300 can slide into the mounting groove 40 along its length, or be pressed, snapped, or embedded into the mounting groove 40 through its opening. The mounting groove 40 allows the lateral limiting member 100 to have both lateral limiting and external connection functions. In this embodiment, the mounting groove 40 is provided on the limiting body 10, enabling the external accessory 300 to form a connection with the lateral limiting member 100. This allows the lateral limiting member 100 to provide lateral constraint between adjacent plates 201 while providing installation positions for decorative pieces, finishing pieces, hanging pieces, fixing seats, keel connectors, positioning pieces, or other functional components.

[0091] In the above embodiment, when the mounting groove 40 and the limiting part 20 are set on the same limiting body 10, the connecting force, supporting force or fixing force of the external accessory 300 acting on the transverse limiting part 100 can be transmitted to the limiting body 10; the limiting body 10 then forms a positional association with the adjacent plates 201 through the limiting parts 20 on both sides, thereby forming an interconnected connection system between the external accessory 300, the transverse limiting part 100 and the adjacent plates 201, which is beneficial to improving the overall stability of the splicing part.

[0092] In some embodiments, such as Figure 13 and Figure 14 As shown, a tapering structure 41 can be provided at the opening of the mounting groove 40, and the tapering structure 41 can be a flange, retaining edge, inward flange, narrowing, lip, shoulder, or other locally narrowing structure extending into the mounting groove 40. For example... Figure 19 and Figure 20 As shown, the constriction structure 41 reduces the effective opening size of the mounting groove 40, constraining the external accessory 300 in a direction perpendicular to the extension direction of the mounting groove 40 after it enters the mounting groove 40. For example, when the external accessory 300 has a wide connector or plug-in portion, it can first slide into the mounting groove 40 from the end along its length, and then the constriction structure 41 restricts the external accessory 300 from coming out of the groove. Of course, when the external accessory 300 has an elastically deformable plug-in portion, it can also be pressed through the constriction structure 41 to enter the mounting groove 40. Alternatively, the constriction structure 41 can be elastically deformable, allowing the plug-in portion of the external accessory 300 to be pressed through the constriction structure 41 to enter the mounting groove 40. The constriction structure 41 provides a certain anti-detachment or limiting effect to the mounting groove 40, thereby improving the connection stability between the external accessory 300 and the limiting body 10.

[0093] In some embodiments, such as Figure 13 and Figure 14 As shown, the mounting slot 40 can adopt a dovetail-shaped slot or a slot structure with dovetail-shaped limiting features. The dovetail-shaped limiting feature can be understood as the transverse dimension inside the slot being larger than the slot opening size, or the slot wall having opposing limiting portions, making it difficult for the external fitting 300 inserted into the slot to detach directly in the direction perpendicular to the slot opening. For example... Figure 19 and Figure 20 As shown, the external accessory 300 can be adjusted in position in the extension direction of the groove by means of a dovetail groove or a groove structure with dovetail limiting features, while being limited in other directions, thus taking into account both position adjustability and assembly stability.

[0094] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, the limiting body 10 is provided with an elastic damping lip 50, which can be located on the surface of the limiting body 10 facing the plate 201 or the surface facing the mounting base, and is positioned opposite to the mechanical joint structure 30. Alternatively, it can be located at points where the limiting body 10 may come into contact with other components. The elastic damping lip 50 can be an elastic strip, flexible flange, elastic sheet, covering layer, soft pad, or a deformable structure partially formed by the limiting body 10. When the plate 201 is assembled to the transverse limiting member 100, the elastic damping lip 50 can elastically contact the plate 201; when the transverse limiting member 100 is installed on a mounting base such as a keel, the elastic damping lip 50 can also elastically contact the mounting base. Because the elastic damping lip 50 has a certain compressive deformation capacity, it can adapt to fill gaps, dimensional tolerances, or local unevenness between the plate 201, the limiting body 10, and the mounting base by undergoing adaptive deformation. Furthermore, the elastic damping lip 50 can reduce the direct hard impact between the plate 201 and the limiting body 10 to a certain extent. When the plate is subjected to trampling, vibration, wind load or thermal expansion and contraction and produces a small displacement, the elastic damping lip 50 can first compress or rebound, weakening the instantaneous impact between rigid components, thereby helping to reduce abnormal noises caused by local friction, impact or relative micro-movement, and can make the contact load more evenly distributed within a certain range.

[0095] In the above embodiments, when the elastic damping lip 50 is combined with the mechanical joint structure 30, it can provide a certain flexible contact interface for the plate while keeping the joint position restricted. That is, the limiting step 31 can undertake the function of limiting the assembly position of the plate 201, and the elastic damping lip 50 can undertake the function of local buffering and error compensation. The two can form a combination of rigid positioning and elastic buffering, which is conducive to taking into account both the assembly positioning accuracy and the contact stability during use.

[0096] In some embodiments, a protective layer may be provided on the surface of the limiting body 10. This protective layer may be provided on all or part of the surface of the limiting body 10, or only on the limiting part 20, the mechanical joint structure 30, the mounting groove 40, the closing structure 41, or other areas that are easily exposed to the external environment, the plate 201, or the external accessories 300. The protective layer can be formed by coating, film coating, spraying, oxidation, electroplating, impregnation, encapsulation, co-extrusion, or other suitable methods. The protective layer can improve the surface wear resistance, weather resistance, corrosion resistance, scratch resistance, or surface stability of the limiting body 10. In outdoor environments, humid environments, environments with varying temperature differences, or operating conditions requiring frequent installation and disassembly, the lateral limiting member 100 may be affected by friction, dust, moisture, salt spray, ultraviolet radiation, or other environmental factors. By providing a protective layer in the corresponding areas, the possibility of performance changes caused by direct exposure or frequent friction to the surface of the limiting body 10 can be reduced, and it is beneficial to maintain the long-term fit between the limiting part 20 and the slot 2011, and between the mounting groove 40 and the external accessories 300.

[0097] In some embodiments, such as Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, the limiting body 10 may be provided with weight-reducing holes 60, which may be formed in the central area of ​​the limiting body 10, non-major load-bearing areas, the periphery of the mounting groove 40, or other locations that do not affect the limiting function. The weight-reducing holes 60 may be round, elongated, oblong, polygonal, irregularly shaped, through, or non-through recessed. Furthermore, the weight-reducing holes 60 may be continuously arranged along the length of the limiting body 10, or multiple holes may be spaced apart. By providing weight-reducing holes 60, the amount of local material used in the limiting body 10 can be reduced while meeting the basic structural strength and installation requirements of the lateral limiting component 100, thereby reducing the component's self-weight. For situations where multiple lateral limiting components 100 need to be deployed in a large paved area, the weight-reducing holes 60 help reduce the burden during transportation, handling, and on-site installation. At the same time, the weight-reducing holes 60 can also, under certain conditions, create space for drainage, dehumidification, ventilation, observation, positioning, or installation clearance. Of course, the shape, number, position and size of the weight reduction holes 60 can be set according to the force conditions of the limiting body 10, the manufacturing process and the usage environment, and this application does not limit them.

[0098] In some embodiments, such as Figures 1 to 18 As shown, the limiting body 10 can be made of a metallic material, which can be a metal or metal alloy suitable for bearing connection loads and environmental loads, such as stainless steel, carbon steel, alloy steel, aluminum, aluminum alloy, magnesium alloy, copper, copper alloy, zinc alloy, titanium, or titanium alloy. When a metallic material is used, the limiting body 10 can have good structural support capabilities, allowing the limiting part 20, the mechanical joint structure 30, and the mounting groove 40 to maintain a predetermined relative positional relationship under corresponding loads. When the lateral limiting member 100 needs to withstand large lateral forces, repeated installation forces, or connection forces transmitted by the external accessories 300, the metallic limiting body 10 can provide a stable load-bearing foundation. Meanwhile, a protective layer can be provided on the surface of the metal limiting body 10. The protective layer can be a zinc plating layer, nickel plating layer, chromium plating layer, hot-dip galvanizing layer, electrophoretic layer, powder coating layer, powder coating, anodizing layer, passivation layer, anti-corrosion paint layer or other corrosion-resistant protective layer to improve the corrosion resistance and service life of the lateral limiting part 100 in humid, salt spray, sunlight, temperature difference changes or outdoor environments.

[0099] In some embodiments, such as Figures 1 to 18 As shown, the limiting body 10 can be made of engineering plastics, which can possess good insulation, weather resistance, lightweight properties, or ease of molding. When using engineering plastics, the limiting body 10 can be formed into more complex limiting parts 20, deformation spaces 23, mechanically fixed joint structures 30, mounting grooves 40, or weight-reducing holes 60 through injection molding, compression molding, or other methods. Simultaneously, engineering plastics can also give certain areas a certain degree of elasticity, thus making them suitable for forming elastic springs 21, elastic shock-absorbing lips 50, or other flexible mating structures.

[0100] In some embodiments, such as Figures 1 to 18As shown, the limiting body 10 may also include different functional areas formed of different materials. For example, the main load-bearing area may be made of materials with high strength, rigidity, and corrosion resistance, specifically stainless steel, carbon steel, alloy steel, galvanized steel, aluminum alloy, magnesium alloy, titanium alloy, zinc alloy, glass fiber reinforced nylon, glass fiber reinforced polypropylene, glass fiber reinforced polycarbonate, or other fiber-reinforced engineering plastics; the elastic tongue 21 may be made of materials with good elastic recovery ability, fatigue resistance, and weather resistance, specifically spring steel, stainless steel spring strip, beryllium copper, phosphor bronze, titanium alloy, elastic aluminum alloy, polyoxymethylene, polyamide, thermoplastic polyurethane elastomer, thermoplastic polyester elastomer, thermoplastic vulcanized rubber, thermoplastic elastomer, or other metal or polymer materials suitable for repeated elastic deformation; the elastic damping lip 50 may be made of materials with low hardness, good damping and cushioning performance, wear resistance, and The material is made of weather-resistant elastic material, specifically natural rubber, nitrile rubber, EPDM rubber, silicone rubber, neoprene rubber, fluororubber, polyurethane elastomer, thermoplastic polyurethane elastomer, thermoplastic vulcanized rubber, thermoplastic polyolefin elastomer, ethylene-vinyl acetate copolymer, or soft polyvinyl chloride. Alternatively, the limiting body 10 can also be a composite structure combining a rigid body and an elastic covering. The rigid body can be made of stainless steel, aluminum alloy, galvanized steel, engineering plastics, glass fiber reinforced nylon, or glass fiber reinforced polypropylene. The elastic covering can be made of EPDM rubber, silicone rubber, thermoplastic polyurethane elastomer, thermoplastic vulcanized rubber, thermoplastic polyolefin elastomer, thermoplastic elastomer, or polyurethane elastomer. The rigid body and the elastic covering can be connected by secondary injection molding, overmolding, insert injection molding, co-extrusion molding, hot pressing, bonding, snap-fitting, mechanical fitting, or other suitable methods. By combining the properties of different materials, the lateral limiting component 100 can perform the functions of lateral limiting and joint fixing between adjacent plates 201, while also taking into account the needs of elastic assembly, spring-loaded self-locking, shock absorption and buffering, noise reduction, wear prevention and protection of the contact parts of the plates 201.

[0101] In some embodiments, such as Figure 13 and Figure 14 As shown, the lateral limiting member 100 can be configured as a limiting body 10 with different contour shapes. The limiting body 10 still has limiting portions 20 on both sides, and a mechanical joint structure 30 and a mounting groove 40 can still be provided in the middle. However, the relative positions of the limiting portions 20, mounting grooves 40, or limiting steps 31 can be adjusted according to the cross-sectional shape of the plate 201. For example, when the slot 2011 of the plate 201 is located near the lower part of the plate, the limiting portion 20 can extend downwards accordingly; when the external accessory 300 needs to be connected from above, the mounting groove 40 can be correspondingly located in the upper region of the limiting body 10.

[0102] It should be noted that the lateral limiting member 100 may also have a different opening direction of the mounting groove 40, a different configuration of the limiting step 31, or a different arrangement of the weight-reducing holes 60 than in the above embodiments. Furthermore, the differences between different embodiments can accommodate different mounting foundations, different plate thicknesses, different plate splicing directions, or different forms of external accessories 300. As long as the lateral limiting member 100 can form a concave-convex fit with the adjacent plate 201 through the limiting portions 20 on both sides, and achieve lateral relative displacement limitation between the adjacent plates 201, it is acceptable.

[0103] The following will combine Figure 19 and Figure 20 The assembly and working processes of the lateral limiting member 100 disclosed in the embodiments of this application will be further explained.

[0104] First, depending on the splicing position of adjacent panels 201, transverse limiting parts 100 can be pre-arranged on the installation foundation, supporting keel, connecting frame or other load-bearing parts.

[0105] Then, the first plate is moved toward the lateral limiting member 100, so that the limiting part 20 on one side of the lateral limiting member 100 is aligned with the slot 2011 of the first plate. As the first plate continues to move, the elastic tongue 21 in the limiting part 20 can elastically deform under the push of the entrance edge of the slot 2011, and the protruding structure 211 enters the inner area of ​​the slot 2011 after passing the entrance edge. The elastic tongue 21 deflects under the clearance conditions provided by the deformation space 23, and forms a return tendency after reaching the predetermined position, so that the protruding structure 211 and the corresponding limiting part in the slot 2011 engage or abut against each other.

[0106] Subsequently, the second plate is installed in a similar manner, so that the limiting part 20 on the other side of the transverse limiting member 100 enters the slot 2011 of the second plate. At this time, the two plates 201 respectively establish a concave-convex fit with the limiting parts 20 on both sides of the transverse limiting member 100. At the same time, the two plates 201 can abut against the corresponding limiting steps 31 of the mechanical jointing structure 30 as they continue to approach the transverse limiting member 100. When both plates 201 abut to the predetermined position, a splicing seam defined by the mechanical jointing structure 30 is formed between the two plates 201.

[0107] When decorative elements such as LED strips are required, LED strip holders, LED strip fasteners, or other compatible decorative accessories can be inserted, slid into, or snapped into the mounting groove 40 to achieve the installation and positioning of the decorative elements on the lateral limiting member 100. Since the mounting groove 40 can extend along the extension direction of the limiting body 10, the decorative elements can be arranged and adjusted according to their actual length, light-emitting position, or decorative effect.

[0108] During use after assembly, if the first plate is subjected to a lateral load and tends to move closer to or further away from the second plate, the slot 2011 of the first plate will interact with the corresponding limiting part 20. After the limiting part 20 bears the force, it transmits the force to the limiting body 10. Since the limiting part 20 on the other side of the limiting body 10 cooperates with the second plate, the limiting body 10 can constrain the relative displacement trend of the first plate through the limiting part 20 and the second plate. Similarly, if the second plate tends to move laterally, a corresponding reaction relationship will occur between the limiting part 20 and the slot 2011 of the second plate. Thus, the two limiting parts 20 can work together to form a double-sided lateral limiting between the two adjacent plates 201, thereby providing corresponding resistance to trends such as adjacent plates moving closer to each other, moving further apart, relative movement, or local misalignment.

[0109] It should be noted that when multiple lateral limiting members 100 are arranged at intervals along the splice joint of adjacent plates 201, the multiple lateral limiting members 100 can form multiple lateral constraint points at different positions of the splice joint. Therefore, when the plate 201 is subjected to lateral load, the load can be borne or shared by multiple lateral limiting members 100, rather than being concentrated on a single connection position. Multiple mechanical joint fixing structures 30 can also jointly limit the spacing of the splice joint along the length direction, which is beneficial to improving the overall assembly stability of long plates, large-area metal components, or continuous splicing structures.

[0110] In some application scenarios, the plate 201 may expand and contract due to changes in ambient temperature. When the mechanical joint structure 30 is set, a gap controlled by the limiting step 31 can be formed between adjacent plates 201, providing corresponding splicing space for changes in plate size. After setting the elastic tongue 21 and the elastic damping lip 50, the lateral limiting member 100 can adapt to the slight positional changes of the plate 201 within the allowable range through local elastic deformation. This allows the lateral limiting member 100 to limit unintended lateral movement while reducing the possibility of local stress concentration caused by rigid top pressure.

[0111] In the above embodiments, the mechanical jointing structure 30 can be used to control or limit the splicing interval of adjacent plates 201, but this does not mean that the adjacent plates 201 are completely free from any dimensional changes caused by environmental influences during use. Structures such as the elastic tongue 21, deformation space 23, and elastic damping lip 50 can provide a certain degree of adaptability to assembly errors, local deformation, or minor displacements; the interlocking fit between the limiting part 20 and the slot 2011 can limit lateral relative displacement trends exceeding a predetermined range. The combination of rigid limiting, mechanical spacing, and elastic compensation improves the adaptability of the splicing structure to the actual installation and usage environments.

[0112] like Figure 20 As shown in the illustration, this application also discloses a metal component 200, including at least two adjacent plates 201 and a lateral limiting member 100 as disclosed in the above embodiment. Therefore, it possesses all the technical effects of the aforementioned lateral limiting member 100, which will not be repeated here. The lateral limiting member 100 is disposed between two adjacent plates 201, and the limiting portions 20 on both sides of the lateral limiting member 100 are respectively connected to the corresponding side plates 201 in a concave-convex fit to limit the lateral relative displacement between the two adjacent plates 201.

[0113] In some embodiments, the metal component 200 can be a metal floor, metal wall panel, metal decorative panel, metal grille panel, metal profile panel, metal curtain wall panel, metal platform panel, metal walkway panel, or other metal components 200 with splicing requirements. The panel body 201 may include a panel body main body, side connecting parts, slots 2011, reinforcing parts, decorative surfaces, or other functional parts. The slots 2011 can be structures formed by molding the panel body 201 itself, or structures formed through subsequent processing. The slots 2011 can extend continuously along the length of the panel body 201, or can be partially disposed at positions corresponding to the lateral limiting member 100.

[0114] In some embodiments, the metal component 200 may also include external accessories 300 for decoration, such as light strips and fasteners. The external accessories 300 can be connected to the lateral limiting member 100 through the mounting groove 40, thereby reducing the number of parts used to fix the external accessories 300, improving the ease of assembly and disassembly of the external accessories 300, and saving costs.

[0115] In some embodiments, the metal component 200 can be used in villa courtyards, outdoor terraces, waterfront boardwalks, urban parks, cultural and tourism scenic spots, commercial plazas, building rooftop platforms, indoor floors, indoor walls, partition decorations, exhibition spaces, or other prefabricated panel splicing scenarios. Of course, the metal component 200 can also be used in assembling landscape profiles, combined grille strips, prefabricated trim lines, panel enclosure components, or other splicing structures that require control of the lateral relative position of adjacent components. In outdoor paving scenarios, multiple panels 201 can be arranged along a predetermined direction to form a continuous paving surface. Lateral limiting members 100 can be set between any two adjacent panels 201, or multiple members can be spaced along the splicing seam. The cooperation between the limiting part 20 and the slot 2011 is used to limit the lateral relative movement of the panels; the mechanical jointing structure 30 is used to maintain a predetermined splicing interval between adjacent panels; the mounting groove 40 can cooperate with the external accessory 300 to achieve diverse functional adaptations, thereby enabling multiple panels 201 in the continuous paving surface to obtain corresponding lateral constraints and splicing seam control at multiple splicing positions. In wall or facade installation scenarios, the panels 201 can be arranged vertically, horizontally, or obliquely. The installation direction of the horizontal limiting member 100 can be adjusted according to the splicing direction of the panels 201. As long as the limiting parts 20 on both sides can form a concave-convex fit with the corresponding slots 2011 of the adjacent panels 201, and the mechanical jointing structure 30 can form an interval limiting relationship with the corresponding positions of the panels, the lateral position constraint between adjacent panels 201 can be achieved.

[0116] In some embodiments, the lateral limiting member 100 can be installed facing forward, backward, sideways, or in a positional relationship suitable for mating with the slot 2011 of the plate 201. The specific orientation of the limiting body 10 can be determined by the position of the mounting groove 40, the connection method of the external accessory 300, the position of the slot 2011 of the plate 201, and the structure of the mounting base. As long as the limiting part 20 can form an effective concave-convex fit with the adjacent plate 201, the installation orientation of the lateral limiting member 100 can be adjusted according to the actual construction conditions.

[0117] In some embodiments, the lateral limiting member 100 can be cut to a structure suitable for the length of a local splicing area, or it can be arranged continuously or segmentally along the length of a longer splicing area. Multiple segmented lateral limiting members 100 can be spaced apart from each other, adjacent to each other, or located at different stress positions. The specific arrangement can be selected and determined according to the length of the splicing area, the size of the plate, and the load conditions, so that the limiting structure is adapted to the actual installation requirements.

[0118] It should be noted that in the above embodiments, terms such as "first," "second," "both sides," "middle," "upper," "lower," "inner," and "outer" are mainly used to describe and distinguish different structures, positions, or directions, and should not be construed as limitations on relative importance, absolute position, assembly order, or quantity. Unless otherwise explicitly defined, terms such as "connection," "installation," "fixing," "fitting," "abutting," and "clamping" can indicate direct connection, installation, fixing, or fitting, or indirect connection, installation, fixing, or fitting achieved through intermediate components; they can be detachable or non-detachable connections. In this application, "lateral" can be understood as the direction in which adjacent panels may move relatively, move closer, move further apart, or misalign after being spliced, and can be specifically determined based on the laying direction of the panel 201, the extension direction of the splice seam, and the setting direction of the installation foundation.

[0119] The terminology used in the above embodiments is for the purpose of describing specific embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this application, "one or more" refers to one, two, or more; "and / or" describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0120] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0121] The terms "parallel" and "perpendicular" used in this application refer to "basically parallel" and "basically perpendicular" in practical operation. "Basically parallel" can be understood as parallelism with a certain degree of error, and similarly, "basically perpendicular" can be understood as perpendicularity with a certain degree of error.
