DETAILED DESCRIPTION ​​

[0059] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0060] In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. "A plurality of" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified. The terms "installed," "connected," and "linked" should be interpreted broadly, for example, they can be a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; they can be the internal communication of two devices or the interaction relationship of two devices, unless otherwise explicitly specified. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0061] In the description of this application, the terms "first direction" and "second direction" are introduced to more clearly illustrate the structure of each component in the covering element 10 of this application and their relative positional relationships after installation (laying). In the accompanying drawings of this application, the first direction Z is indicated by an arrow labeled Z. Typically, the first direction Z corresponds to the thickness direction of the covering element 10. When the covering element 10 is laid on the ground, the first direction Z corresponds to the vertical direction. In the accompanying drawings of this application, the second direction X is indicated by an arrow labeled X. The second direction X is perpendicular to the first direction Z, with the first direction Z as a reference. Specifically, after the covering element 10 is laid, the second direction X corresponds to the arrangement direction of an adjacent first plate 100 and a second plate 200. It is understood that the second direction X of an adjacent pair of first plates 100 and second plates 200 may be different from the second direction X of another adjacent pair of first plates 100 and second plates 200.

[0062] As the prologue of the present application, the current floor connecting mode is mainly tenon and mortise connection, that is, the tenon and mortise of the boards are embedded to realize the mutual locking connection between the boards. This connection mode is not stable enough, especially when the boards swell, the connection is easy to loosen. In addition, there is also a connecting mode of setting a fillet between the boards, which opens an assembly groove in the middle of the opposite end faces of the boards, and then the fillet is arranged in the assembly groove before the boards are embedded, and then the boards are embedded and combined. This connection mode increases the difficulty of assembly, and after laying, the fillet is buried in the interior of the adjacent boards, which cannot be observed from the outside. When it is necessary to replace the boards, it is not easy to disassemble the adjacent boards due to the effect of the internal fillet, which may need to be destructively removed, affecting the secondary use.

[0063] Therefore, the present application provides a covering element 10 which can be used for covering and decorating indoor and / or outdoor floors. Specifically, the covering element 10 corresponds to a part of the floor, which can be one or more combined structural units used for floor laying. By laying a plurality of covering elements 10 to achieve overall covering, decoration and protection of the floor, the floor laying is completed. The covering element 10 uses a locking structure (insert buckle 300) to lock the force between the boards (first board 100 and second board 200) in the first direction Z, and uses the interaction between the boards to lock the force in the second direction X, so as to realize the connection by mutual cooperation. This can not only improve the stability of the connection, but also improve the user experience.

[0064] Please refer to Figure 1 The covering element 10 provided by the present application includes a first board 100, a second board 200 and an insert buckle 300. The first board 100 and the second board 200 are board structures of the covering element 10, which are used for mutual connection to cover and decorate the surface such as the floor. The insert buckle 300 is used for locking the first board 100 and the second board 200, so that the first board 100 and the second board 200 can be stably connected.

[0065] It should be noted that the covering element 10 has an unassembled state and an assembled state. The unassembled state is a state in which the covering element 10 is not installed on the surface of the ground or the like, and in the unassembled state, the first plate 100, the second plate 200 and the insert buckle 300 are not assembled and connected together, and installation and paving procedures need to be performed to combine the first plate 100, the second plate 200 and the insert buckle 300 with each other. The assembled state is a state in which the covering element 10 is installed on the surface to be covered, and in the assembled state, the first plate 100, the second plate 200 and the insert buckle 300 are assembled and connected together. It can be understood that the covering element 10 can be in the assembled state or in the unassembled state. In order to clearly describe the structure and assembly relationship of each component in the covering element 10, the following mainly describes the assembled state.

[0066] Please refer to Figures 1 to 4 , the first plate 100 is provided with a first edge structure 110, the second plate 200 is provided with a second edge structure 210, and the first edge structure 110, the second edge structure 210 and the insert buckle 300 cooperate with each other to enable the first plate 100 to be installed on at least one side of the second plate 200, and also enable the second plate 200 to be installed on at least one side of the first plate 100. Among them, the first edge structure 110 is an assembly structure provided on at least one side edge of the first plate 100, and the second edge structure 210 is an assembly structure provided on at least one side edge of the second plate 200. Optionally, the first plate 100 and the second plate 200 are both integral structures, and can be integrally machined and formed respectively. After forming, at least one side edge of the first plate 100 is the first edge structure 110, and at least one side edge of the second plate 200 is the second edge structure 210.

[0067] Specifically, please refer to Figure 6 The first edge structure 110 is provided with a limiting gap 120 on one side in the first direction Z. The limiting gap 120 is a groove recessed from one side of the first edge structure 110 to the other side along the first direction Z. The second edge structure 210 includes a limiting structure 211, which is arranged on one side of the first edge structure 110 in the first direction Z and partially located in the limiting gap 120 in the assembled state. Thus, part of the second edge structure 210 is embedded into the limiting gap 120 to limit the first edge structure 110 in the second direction X. Through the cooperation of the limiting structure 211 and the limiting gap 120, the first edge structure 110 and the second edge structure 210 can be limited in the second direction X, so that the first plate 100 and the second plate 200 are locked in the second direction X. In the second direction X, an acting force is applied to the first plate 100 and the second plate 200 respectively, and due to the cooperation of the limiting structure 211 and the limiting gap 120, the first plate 100 and the second plate 200 can be locked and thus will not be easily separated.

[0068] Please combine Figure 7 , the second edge structure 210 and the first edge structure 110 form a slot 400 therebetween, the slot 400 is formed by the first end face of the first edge structure 110 and the second end face of the second edge structure 210. Wherein, the first end face is the face of the first edge structure facing the second edge structure 210, and the second end face is the face of the second edge structure 210 opposite to the first end face. The slot 400 is located on the side of the first edge structure 110 away from the limiting structure 211, and the slot 400 is provided with a notch 410 on the side away from the limiting structure 211. That is, part of the structure of the first edge structure 110 is located between the slot 400 and the limiting structure 211. Please combine Figure 3 、 Figure 4 and Figure 7 , part of the structure of the first edge structure 110 is located below the slot 400, the limiting structure 211 is located below the part of the structure of the first edge structure 110, and the notch 410 of the slot 400 is provided on the side facing away from the limiting structure 211. And the bottom of the slot 400 can be made by combining the first edge structure 110 and the second edge structure 210 (such as Figure 3 ), or it can be formed by part of the structure of the first edge structure 110 (such as Figure 4 ).

[0069] Please refer to Figures 1 to 4 , the plug 300 can be embedded in the slot 400 and exposed from the notch 410, and the plug 300 is arranged to press the first edge structure 110 on the limiting structure 211. Specifically, the plug 300 abuts against the first edge structure 110 and the second edge structure 210 to press the first edge structure 110 on the limiting structure 211. Wherein, in the direction perpendicular to the first direction Z and the second direction X, the plug 300 and the slot 400 are generally in the shape of a long strip (see Figure 1 ), the plug 300 is embedded in the slot 400, and from above the notch 410 of the slot 400, the part of the plug 300 exposed from the notch 410 can be observed. Thus, the plug 300 can be used to fill the gap between the first plate 100 and the second plate 200 formed by the slot 400, and can play the role of caulking, so it is particularly suitable for stone texture floor products, and can improve the user experience.

[0070] It can be understood that by opening the limiting gap 120 on one side of the first edge structure 110 in the first direction Z, in the assembled state, the limiting structure 211 of the second edge structure 210 is arranged on one side of the first edge 110 in the first direction Z, and part of the limiting structure 211 is embedded in the limiting gap 120. Thus, by cooperation of the limiting structure 211 and the limiting gap 120, the first edge structure 110 and the second edge structure 210 can be limited in the second direction X, and the first plate 100 and the second plate 200 can be locked in the second direction X. By embedding the plug 300 into the slot 400 between the first edge structure 110 and the second edge structure 210, the plug 300 can abut against the first edge structure 110 and the second edge structure 210 to apply pressure to the first edge structure 110 and the second edge structure 210, and press the first edge structure 110 on the limiting structure 211, thereby locking the first plate 100 and the second plate 200 in the first direction Z, and ensuring the stability of the connection. By embedding the plug 300 in the slot 400 and exposing the slot opening 410 of the slot 400, the plug 300 can fill the gap between the first plate 100 and the second plate 200 formed by the slot 400, play a filling and caulking role, and also facilitate the disassembly and replacement of the first plate 100 and / or the second plate 200 from the slot opening 410, thereby improving the user experience.

[0071] Please see Figure 5 , Figure 6 and Figure 7In some embodiments, the second edge structure 210 comprises a body 213 configured to form the slot 400 together with the first edge structure 110, i.e. the body 213 is a part of the second edge structure 210 for forming the slot 400 together with the first edge structure 110, and the limiting structure 211 is connected to the body 213 at a side close to the first plate 100. The limiting structure 211 comprises a connecting block 2111 and a limiting block 2112. The connecting block 2111 is connected to the body 213 and extends from the body 213 in the first direction Z. The connecting block 2111 is configured to hold a part of the first edge structure 110 in the first direction Z by the clasp 300. That is, in the assembled state, at least a part of the first edge structure 110 is located between the clasp 300 and the connecting block 2111 in the first direction Z, and the clasp 300 exerts pressure on the part of the first edge structure 110 to press it against the connecting block 2111. The limiting block 2112 is connected to the connecting block 2111 at a side away from the body 213, and is embedded in the limiting gap 120. The limiting block 2112 is configured to hold a part of the first edge structure 110 in the second direction X by the clasp 300. That is, in the assembled state, at least a part of the first edge structure 110 is located between the clasp 300 and the limiting block 2112 in the second direction X, and the clasp 300 exerts pressure on the part of the first edge structure 110 to press it against the limiting block 2112.

[0072] By arranging the connecting block 2111 at a side of the first edge structure 110 away from the clasp 300 in the first direction Z, the first edge structure 110 can be pressed against the connecting block 2111 by the clasp 300 to lock the first plate 100 and the second plate 200 in the first direction Z. By arranging the limiting block 2112 at a side of the connecting block 2111 away from the body 213, the limiting block 2112 can cooperate with the limiting gap 120 of the first edge structure 110 to lock the first plate 100 and the second plate 200 in the second direction X.

[0073] Please refer to Figure 5 , Figure 7 and Figure 8In some embodiments, the limiting block 2112 has a first limiting surface 2113 located on a side of the limiting block 2112 close to the body 213, the first limiting surface 2113 is attached to the first side wall 121 of the limiting gap 120, and an included angle a between the first limiting surface 2113 and the second direction X satisfies: a≤90°. By controlling the included angle a within 90°, the force exerted by the first limiting surface 2113 on the first edge structure 110 is entirely or partially along the second direction X, which can more stably limit the first edge structure 110 and improve the stability of the locking between the first plate 100 and the second plate 200 in the second direction X. In particular, when the included angle a<90°, the force exerted by the first limiting surface 2113 on the first edge structure 110 also has a component pointing to the connecting block 2111, which can generate a small amount of pressure on the first edge structure 110 towards the connecting block 2111, improving the connection stability of the first plate 100 and the second plate 200 in the first direction Z. Alternatively, the included angle a can be 90°, 85°, 80°, 75°, 70°, 65°, 60°, or any range value between any two angle values.

[0074] In some embodiments, the body 213 has an assembly surface 2131 connected to a side of the connecting block 2111 away from the limiting block 2112, and an included angle β between the assembly surface 2131 and the second direction X satisfies: β≤a. Specifically, the assembly surface 2131 is the surface of the body 213 opposite to the first limiting surface 2113. By setting the included angle β between the assembly surface 2131 and the second direction X as β≤a, the first edge structure 110 can be more easily inserted into the assembly groove 220 between the assembly surface 2131 and the first limiting surface 2113. Please refer to Figure 5 、 Figure 8 Since when β<a, the included angle β of the assembly surface 2131 is smaller than the included angle a of the first limiting surface 2113, that is, the assembly surface 2131 is more inclined than the first limiting surface 2113, which makes the opening of the assembly groove 220 on the side of the assembly surface 2131 larger, so that the first edge structure 110 is more easily assembled into the assembly groove 220. As Figure 9 The second plate 200 can be laid on the surface to be covered, and then the first plate 100 can be placed vertically into the assembly groove 220 parallel to the surface to be covered and in the direction indicated by the arrow between the first plate 100 and the second plate 200, and then according to the included angle a, a small amount of leftward translation adjustment can complete the assembly of the first plate 100 and the second plate 200. This arrangement can greatly reduce the installation difficulty of the covering element 10 and improve the installation efficiency.

[0075] Please refer again to Figures 5 to 9In some embodiments, the assembly groove 220 is formed by the assembly surface 2131 and the connecting block 2111 and the first limiting surface 2113, and the first edge structure 110 can be partially arranged in the assembly groove 220. In the first direction Z, the insertion slot 400 is above the assembly groove 220; in the second direction X, the insertion slot 400 is at least partially on the side of the assembly groove 220 away from the limiting gap 120. In this way, in the assembled state, the insertion buckle 300 can more stably press the first edge structure 110 on the second edge structure 210, maintaining the installation stability of the covering element 10.

[0076] Please refer to Figure 6 、 Figure 7 and Figure 8 In some embodiments, the limiting block 2112 has a second limiting surface 2114, which is arranged opposite to the first limiting surface 2113 and is attached to the second side wall 122 of the limiting gap 120, the second side wall 122 is arranged opposite to the first side wall 121, and the second limiting surface 2114 is arranged as an arc surface. Arranging the second limiting surface 2114 as an arc surface can increase the structural strength of the limiting block 2112 and improve the service life of the covering element 10, and can also reduce the assembly difficulty of the first plate 100 and the second plate 200 and improve the installation efficiency.

[0077] Please refer to Figure 10 、 Figure 11 and Figure 12 In some embodiments, the insertion buckle 300 is provided with a support portion 320 on both sides, the support portion 320 on one side is arranged to abut against the first edge structure 110, and the support portion 320 on the other side is arranged to abut against the second edge structure 210. Specifically, in the assembled state, the support portion 320 is arranged on both sides of the insertion buckle 300 in the second direction X, and the support portion 320 is arranged to protrude to both sides of the insertion buckle 300, so as to abut against the first edge structure 110 and the second edge structure 210 respectively, and apply force to the first edge structure 110 and the second edge structure 210 by the support portion 320. In this way, on the one hand, the force of the first edge structure 110 and the second edge structure 210 in the second direction X is locked, and on the other hand, the first edge structure 110 can be more stably pressed on the limiting structure 211, ensuring the stability of the overall structure.

[0078] In some embodiments, the insertion buckle 300 is provided with a relief groove 360 between the two support portions 320, which are arranged to be pressed by the first edge structure 110 and the second edge structure 210 and can be elastically deformed towards the relief groove 360. By providing the relief groove 360 in the insertion buckle 300 and arranging the relief groove 360 between the support portions 320, the elastic performance of the insertion buckle 300 can be improved, so that the support portions 320 have a space for deformation when being pressed. In this way, on the one hand, the installation difficulty of the insertion buckle 300 can be reduced, and the elastic deformation of the support portions 320 towards the relief groove 360 can facilitate the installation of the insertion buckle 300 into the insertion slot 400 from the slot opening 410; on the other hand, the elastic supporting performance of the support portions 320 can be improved, so that the support portions 320 can more stably abut against the first edge structure 110 and the second edge structure 210, thereby more stably applying a force to the first edge structure 110 and the second edge structure 210, and ensuring the stability of the connection between the first plate 100 and the second plate 200.

[0079] Optionally, the insertion buckle 300 comprises a base portion 310, and the support portions 320 are connected to the two sides of the base portion 310 to form an integrated structure with the base portion 310. Please refer again to Figure 10 , the support portions 320 and the base portion 310 surround the relief groove 360, which is located between the support portions 320 and the base portion 310. In this way, the relief groove 360 is located on the inner side of the support portions 320, and when the support portions 320 are pressed by the first edge structure 110 and the second edge structure 210, they can be elastically deformed towards the relief groove 360.

[0080] Optionally, please refer again to Figure 12 , the relief groove 360 is provided in the middle region of the insertion buckle 300, that is, the relief groove 360 can be provided on the base portion 310. In this way, the relief groove 360 is also located on the inner side of the support portions 320, and when the support portions 320 are pressed by the first edge structure 110 and the second edge structure 210, they can also be elastically deformed towards the relief groove 360.

[0081] Please refer to Figure 13In some embodiments, the first edge structure 110 comprises a first boss 111, the second edge structure 210 comprises a second boss 212 capable of being arranged opposite to the first boss 111 in the second direction X, and the slot 410 is arranged between the first boss 111 and the second boss 212; the first boss 111 is arranged to be capable of pressing on the support part 320 on one side, and the second boss 212 is arranged to be capable of pressing on the support part 320 on the other side, so as to limit the plug-in buckle 300 in the plug-in slot 400. In the assembled state, the first boss 111 and the second boss 212 are arranged opposite to each other. When the plug-in buckle 300 is embedded into the plug-in slot 400, the first boss 111 and the second boss 212 can be limited above the two support parts 320 respectively, so as to limit the plug-in buckle 300 in the plug-in slot 400, so that the plug-in buckle 300 cannot be squeezed out from the slot 410 by the first plate 100 and the second plate 200, thereby maintaining the stability of the connection between the first plate 100 and the second plate 200. Moreover, since the first boss 111 and the second boss 212 press on the respective corresponding support parts 320, the support parts 320 are subjected to downward pressure, which can further press the first edge structure 110 tightly on the limiting structure 211 of the second edge structure 210, thereby improving the locking effect of the first plate 100 and the second plate 200 in the first direction Z.

[0082] For reference Figures 10 to 13 In some embodiments, the plug-in buckle 300 further comprises a sealing part 330 connected to the base part 310 of the plug-in buckle 300, and the sealing part 330 is arranged to abut between the first boss 111 and the second boss 212 and seal the slot 410. By sealing the slot 410 with the sealing part 330, it is possible to block the external dust, liquid and other dirt from entering the plug-in slot 400, thereby reducing the intrusion of dirt into the gap between the first plate 100 and the second plate 200, and also beautifying the plug-in slot 400, i.e. beautifying the gap between the first plate 100 and the second plate 200, thereby improving the user experience. In particular, the covering element can be used for stone texture floor, and the sealing part 330 of the plug-in buckle 300 is used to simulate the sealant between the plates, thereby improving the appearance and laying effect.

[0083] Specifically, the sealing part 330 can be arranged above the base part 310 and the support parts 320, and the base part 310, the support parts 320 on both sides of the base part 310 and the sealing part 330 above the base part 310 are connected as an integral structure. In the assembled state, the support parts 320 abut against the first edge structure 110 and the second edge structure 210 respectively and are located below the first boss 111 and the second boss 212, and the sealing part 330 is arranged between the first boss 111 and the second boss 212 and abuts against the first boss 111 and the second boss 212 respectively. In this way, the sealing property of the gap between the first plate 100 and the second plate 200 can be effectively maintained.

[0084] Please refer to Figure 10 In some embodiments, the support portion 320 is connected to both sides of the base portion 310 and forms an avoidance groove 360 with the base portion 310; the two sides of the sealing portion 330 are provided with a buffer portion 340, which extends from the sealing portion 330 into the avoidance groove 360, and the buffer portion 340 and the support portion 320 are spaced apart from each other; the support portion 320 is arranged to be extruded by the first boss 111 and the second boss 212, and can elastically deform towards the buffer portion 340 and contact the buffer portion 340. By arranging the buffer portion 340 extending into the avoidance groove 360 on both sides of the sealing portion 330, on the one hand, the sealing portion 330 can be strengthened by the buffer portion 340, and the structural strength of the sealing portion 330 is improved, thereby improving the sealing effect; on the other hand, when the support portion 320 elastically deforms into the avoidance groove 360, it can contact the buffer portion 340, and then the buffer portion 340 can buffer the deformation of the support portion 320, reducing the situation that the support portion 320 cannot rebound in place due to excessive deformation, and ensuring the supporting effect of the support portion 320.

[0085] In some embodiments, the buffer portion 340 and the base portion 310 are spaced apart from each other, and the buffer portion 340 is arranged to be extruded by the support portion 320 and can elastically deform towards the base portion 310. Thus, the buffering effect is improved, especially during the process of inserting the buckle 300 into the slot 400 from the slot opening 410, the gap between the buffer portion 340 and the base portion 310 can ensure that the support portion 320 is extruded by the first boss 111 and the second boss 212 with sufficient deformation, and is more smoothly inserted into the slot 400, and at the same time, the elastic performance of the buffer portion 340 is improved, and the reverse force of the buffer portion 340 on the support portion 320 is used to assist the support portion 320 to better rebound and reset, fully ensuring the supporting effect of the support portion 320 on the two first edge structures 110 and the second edge structure 210, and further ensuring the connection stability of the first plate 100 and the second plate 200.

[0086] Please refer to Figure 14 and Figure 15In the second direction X, the slot 400 has a first size L1, the first boss 111 and the second boss 212 have a second size L2, the support portions 320 on both sides of the plug 300 have a third size L3, and the sealing portion 330 has a fourth size L4, which satisfy: L2≤L4≤L1≤L3. The first size L1 is the distance between the contact positions of the first edge structure 110 and the second edge structure 210 and the support portion 320 in the assembled state; the second size L2 is the distance between the contact positions of the first boss 111 and the second boss 212 and the sealing portion 330 in the assembled state; the third size L3 is the distance between the contact positions of the support portions 320 on both sides of the plug 300 and the first edge structure 110 and the second edge structure 210 in the non-assembled state; and the fourth size L4 is the distance between the contact positions of the sealing portion 330 and the first boss 111 and the second boss 212 in the non-assembled state. The above four sizes can be measured by conventional size measurement methods such as vernier caliper and micrometer. Setting the above four sizes to satisfy L2≤L4≤L1≤L3 makes the plug 300 in a slightly compressed state when the cover element 10 is in the assembled state, which can be clamped in the slot 400 and press the first edge structure 110 and the second edge structure 210, thereby improving the stability of the structure as a whole.

[0087] In some embodiments, the material of the plug 300 is an elastic material, which refers to a material that can reversibly deform under stress and return to its original shape and size after the external force is removed. For example, the plug 300 can be made of materials such as rubber, silicone, TPE (Thermoplastic Elastomer), etc., or made of metal materials with elastic deformation capability such as aluminum alloy.

[0088] Please refer to Figure 10 , Figures 11 to 13 In some embodiments, the plug 300 includes an upper surface 350, which is arranged to be exposed to the slot 410, and the upper surface 350 is arranged to be concave. By arranging the upper surface 350 of the plug 300 to be concave, dirt falling on the plug 300 can be collected in the recess, reducing the possibility of entering the slot 400 from both sides of the upper surface. In addition, arranging the upper surface 350 to be concave can also improve the aesthetic appearance after filling the gap between the first plate 100 and the second plate 200, thereby improving the user experience.

[0089] Please refer to Figure 3 and Figure 12In some embodiments, the insert 300 further comprises a lower surface 370, a portion of the lower surface 370 presses on the first edge structure 110, and another portion presses on the second edge structure 210. Such an arrangement can make the first plate 100, the second plate 200 and the insert 300 more stable after assembly.

[0090] Please also refer to Figure 16 、 Figure 17 and Figure 18 In some embodiments, the first plate 100 and the second plate 200 are structurally identical, and each is provided with the first edge structure 110 and the second edge structure 210, which are arranged opposite to each other. Such an arrangement can reduce the number of component specifications and further reduce the assembly difficulty, by using the same plate structure to cooperate with the insert 300 to complete the installation of the covering element 10. In addition, the reduction of component specifications also reduces the processing difficulty and packaging cost.

[0091] Specifically, please refer to Figure 19 In some embodiments, the main body of the plate is substantially rectangular, which has four sides, and in each pair of opposite sides, one side is provided with the first edge structure 110, and the other side is provided with the second edge structure 210. Such an arrangement can meet the demand of laying on a large area surface.

[0092] Please also refer to Figures 20 to 23 In some embodiments, the first plate 100 has a first side 101 and a second side 102 opposite to each other, and both the first side 101 and the second side 102 are provided with the first edge structure 110; the second plate 200 has a third side 201 and a fourth side 202 opposite to each other, and both the third side 201 and the fourth side 202 are provided with the second edge structure 210. Such an arrangement can complete the covering of the surface by alternately arranging the first plate 100 and the second plate 200 and embedding the insert 300 in the slot 400 between adjacent first plate 100 and second plate 200.

[0093] Correspondingly, the application further provides a floor, which can comprise the covering element 10 of any one of the above embodiments, and thus can have all the technical features and technical effects of the covering element 10, which will not be described here. It should be noted that the floor can be a solid wood floor, a composite floor, a solid wood composite floor, a reinforced floor, a PVC (polyvinyl chloride) floor, and a floor made of other materials. The floor can comprise a plurality of the above-mentioned covering elements 10, and the specific number can be determined according to the actual need of the floor area to be laid and the area that can be covered by a single covering element 10. The area of a single covering element 10 can be the area of a structure obtained by assembling one first plate 100 and one second plate 200 through the insert 300.

[0094] In some embodiments, the floor can also be installed on the wall, i.e. the floor is laid on the wall to bring a unique texture and visual effect to the wall.
