Detailed Implementation

[0056] 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.

[0057] In the description of the present application, it needs to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or devices referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. The meaning of "a plurality of" is two or more, at least one of which can be one, two or more, unless otherwise explicitly specified. The terms "mount", "connect", "connect" should be broadly understood, for example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium; it can be the internal communication of two devices or the interaction relationship between two devices, unless otherwise explicitly specified. The terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features.

[0058] As an introduction to the present application, the current floor connection method is mainly the tongue and groove connection, that is, the male tongue of the board and the female groove of the other board are connected by mutual clamping. In order to make the male tongue smoothly embedded in the female groove, the cutting surface of the clamping process needs to be relatively gentle, that is, the stop block on the female groove is relatively low, which will cause the male tongue to be easily pulled out of the female groove, affecting the stability of the floor connection.

[0059] Therefore, the present application provides a floor covering assembly, which corresponds to a part of the floor, specifically, it can be a combined structural unit of floor laying. By laying a plurality of floor covering assemblies to achieve overall coverage, decoration and protection of the ground, the laying of the floor is completed. The floor covering assembly forms a female groove by setting an elastic layer, uses the elastic deformation ability of the elastic layer to reduce the difficulty of assembly and improve the stability of the connection, in addition, the elastic layer can also be used to improve the comfort of the floor feeling.

[0060] Please refer to Figure 1 The floor covering assembly of the present application comprises a first plate 100 and a second plate 200, which are plate structures of the floor covering assembly and are used to connect each other to cover and decorate the ground. Specifically, the second plate 200 is arranged to be connected to at least one side of the first plate 100.

[0061] It should be noted that the ground covering assembly has an unassembled state and an assembled state. The unassembled state is the state in which the ground covering assembly is not installed on the ground, and in the unassembled state, the first plate 100 and the second plate 200 are not assembled and connected together, and need to be installed and laid to combine the first plate 100 and the second plate 200. The assembled state is the state in which the ground covering assembly is installed on the ground, and in the assembled state, the first plate 100 and the second plate 200 are assembled and connected together. It can be understood that the ground covering assembly 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 ground covering assembly, the following mainly describes the assembled state.

[0062] Please combine Figure 2 and Figure 4 The first plate 100 includes a first body layer 110, a stop block 120, and a first elastic layer 130. At least one side of the first body layer 110 is provided with a first limiting groove 140, and the first limiting groove 140 is provided towards the second plate 200, that is, the first limiting groove 140 is provided at the edge of the first body layer 110. The stop block 120 is arranged on the side of the first body layer 110 close to the second plate 200, that is, the stop block 120 is arranged on at least one side of the first body layer 110 provided with the first limiting groove 140, and the stop block 120 is spaced apart from the first body layer 110. The first elastic layer 130 is arranged below the stop block 120 and connects the first body layer 110 and the stop block 120, and the first body layer 110, the first elastic layer 130, and the stop block 120 surround a second limiting groove 150 with an opening 151 upwards. As shown in Figure 4 The stop block 120 is arranged at the edge of the first plate 100, and the first elastic layer 130 is located below the stop block 120 and connects the stop block 120 and the first body layer 110. Thus, the first upper surface 131 of the first elastic layer 130 constitutes the groove bottom wall of the second limiting groove 150, and the first side wall 111 of the first body layer 110 and the second side wall 121 of the stop block 120 respectively constitute the side walls of the second limiting groove 150.

[0063] Please combine Figure 2 and Figure 5 The second plate 200 is provided with an edge structure 220, which is located at the edge of the second plate 200, and the second plate 200 is connected with the first plate 100 through the edge structure 220. Specifically, the edge structure 220 includes a first limiting portion 221 protruding downward and a second limiting portion 222 protruding towards the first plate 100. As shown in Figure 3 When the first plate 100 and the second plate 200 are connected, the first limiting portion 221 is clamped in the second limiting groove 150, and the second limiting portion 222 is clamped in the first limiting groove 140.

[0064] In the embodiment, the first limiting portion 221 can extrude the stopper 120 in the process of connecting the second plate 200 and the first plate 100, the stopper 120 can transmit the extrusion force to the first elastic layer 130, and the first elastic layer 130 can be elastically deformed. Thus, the stopper 120 can be displaced due to the extrusion, the height of the stopper 120 can be changed, and the angle of the opening 151 of the second limiting groove 150 can be changed, so that the first limiting portion 221 can be smoothly embedded into the second limiting groove 150, and the second limiting portion 222 can be smoothly embedded into the first limiting groove 140.

[0065] Please refer to Figure 6 、 Figure 7 and Figure 8 In some embodiments, the process of assembling the floor covering assembly can be roughly divided into three states. As shown in Figure 6 , in the first state, the first plate 100 is laid on the ground, and the second plate 200 is inclined to be close to the first plate 100, so that the second limiting portion 222 moves towards the first limiting groove 140. As shown in Figure 7 , in the second state, a part of the second limiting portion 222 is inserted into the first limiting groove 140, and the first limiting portion 221 is pressed on the inner side of the top corner of the stopper 120. As shown in Figure 8 , in the third state, the second plate 200 is pressed obliquely downwards, the first limiting portion 221 presses the stopper 120 downwards, the stopper 120 transmits the pressure to the first elastic layer 130, the first elastic layer 130 is elastically deformed to be compressed and / or bent downwards, so that the stopper 120 can be offset outwardly and downwardly following the deformation of the first elastic layer 130, the height of the stopper 120 is reduced, and the angle of the opening 151 of the second limiting groove 150 is increased. With the offset of the stopper 120 outwardly and downwardly, the first limiting portion 221 is gradually embedded into the second limiting groove 150, and the second limiting portion 222 is also gradually embedded into the first limiting groove 140. With the reduction or even disappearance of the downward pressure of the first limiting portion 221 on the stopper 120, the first elastic layer 130 restores the shape, the position of the stopper 120 is restored, and the connection between the first plate 100 and the second plate 200 is locked.

[0066] It can be understood that, in the embodiment, the first elastic layer 130 is arranged, which effectively reduces the installation difficulty between the first plate 100 and the second plate 200. Moreover, the first elastic layer 130 can change the position of the stopper 120 in the process of assembly, so that the first plate 100 and the second plate 200 can be more smoothly connected. Thus, the stopper 120 can be arranged higher, and the transverse connection strength between the first plate 100 and the second plate 200 can be improved, the connection stability between the first plate 100 and the second plate 200 can be improved, and the disconnection of the first plate 100 and the second plate 200 can be reduced.Figure 2 The direction perpendicular to the thickness direction Z.

[0067] Please refer to Figure 6 , Figure 7 and Figure 8 , in some embodiments, the stopper 120 can be moved between a first position and a second position, it should be noted that the first position and the second position are two opposite positions, rather than the absolute position in space. The first position is the position of the stopper 120 in the state of not being extruded relative to the first main body layer 110; the second position is the position of the stopper 120 in the state of being extruded outward by the first limiting part 221, relative to the first main body layer 110. In the first position, the stopper 120 has a first height dimension H1, and in the second position, the stopper 120 has a second height dimension H2, satisfying: H1>H2; wherein the first height dimension and the second height dimension are the distance dimension between the upper surface of the stopper 120 and the supporting surface supported by the lower part of the first elastic layer 130, which can be the surface of the assembly tool or the ground. In this embodiment, in the case that the first limiting part 221 extrudes the stopper 120, the stopper 120 can be moved from the first position to the second position, so that the first limiting part 221 is embedded in the second limiting groove 150.

[0068] Optionally, in the first position, the second limiting groove 150 has a first size, and in the second position, the second limiting groove 150 has a second size, satisfying that the first size is smaller than the second size.

[0069] Optionally, the first size and the second size can be the angle of the opening 151 of the second limiting groove 150, that is, the included angle dimension of the two side walls (the first side wall 111 and the second side wall 121) of the second limiting groove 150. In the first position, the angle of the opening 151 of the second limiting groove 150 is relatively small, while in the second position, the stopper 120 is extruded by the first limiting part 221, extruding and deforming the first elastic layer 130, so that the angle of the opening 151 of the second limiting groove 150 becomes larger, and thus the first limiting part 221 can be more easily embedded into the second limiting groove 150.

[0070] Optionally, as shown in Figure 6 and Figure 8 , the first size and the second size are both the width dimension of the opening 151 of the second limiting groove 150, that is, in the first position, the first size is the width dimension L1 of the opening 151 of the second limiting groove 150, and in the second position, the second size is the width dimension L2 of the opening 151 of the second limiting groove 150, satisfying: L1<L2. In the second position, the stopper 120 is extruded by the first limiting part 221, extruding and deforming the first elastic layer 130, thus offsetting outward and downward, resulting in an increase in the width of the opening 151 of the second limiting groove 150, that is, satisfying: L1<L2.

[0071] Please refer to Figure 8 In some embodiments, when the block 120 moves from the first position to the second position, the block 120 extrudes the first elastic layer 130 to generate bending deformation, so that at least part of the first elastic layer 130 is bent downward. Thus, the block 120 can sink, its height relative to the ground is reduced, and the opening 151 of the second limiting groove 150 is increased in angle, so that the first limiting part 221 can be more smoothly embedded into the second limiting groove 150.

[0072] In some embodiments, when the block 120 moves from the first position to the second position, the block 120 extrudes the first elastic layer 130 to generate compression deformation, so that the thickness M of at least part of the first elastic layer 130 is reduced. It can be understood that, when assembled, the lower surface of the first elastic layer 130 is at least partially supported by an assembly tool or the ground. With the movement of the block 120, the block 120 gradually extrudes the first elastic layer 130 downward, so that the first elastic layer 130 is compressed, and thus the thickness M of the part of the first elastic layer 130 below the block 120 is reduced. The height of the block 120 is reduced, so that the first limiting part 221 is more smoothly embedded into the second limiting groove 150.

[0073] Please refer to Figure 3 When the first limiting part 221 is located in the second limiting groove 150, the block 120 is located in the first position. That is, when the first limiting part 221 is located in the second limiting groove 150, the downward pressure of the first limiting part 221 on the block 120 is minimized or even disappears, so that the first elastic layer 130 restores its shape under the action of its elastic restoring force, and then resets the block 120 to the first position. At this time, the height of the block 120 is increased, the limiting effect on the first limiting part 221 is improved, the connection strength of the first plate 100 and the second plate 200 in the transverse direction is increased, and the connection stability of the two is improved.

[0074] Please refer to Figure 2 In some embodiments, the first elastic layer 130 is also arranged below the first main body layer 110, and the first bottom wall 112 of the first main body layer 110 and the second bottom wall 122 of the block 120 are connected with the first upper surface 131 of the first elastic layer 130. That is, the first main body layer 110 has the first elastic layer 130 below it. When the first main body layer 110 is stepped on, the first elastic layer 130 is compressed, which can play a role of elastic buffering, improve the comfort of foot feeling, and improve the user experience. The first bottom wall 112 and the second bottom wall 122 can be connected with the first upper surface 131 of the first elastic layer 130 by adhesive means.

[0075] In some embodiments, the first sidewall 111 of the first main body layer 110 faces the second plate 200, the slot opening 141 of the first limiting slot 140 is located on the first sidewall 111, and the stopper 120 has a second sidewall 121 opposite to the first sidewall 111. Please refer to Figure 9 and Figure 10 , the first elastic layer 130 is connected to the first sidewall 111 and extends towards the second plate 200, the second bottom wall 122 of the stopper 120 is connected to the first upper surface 131 of the first elastic layer 130, and the first upper surface 131, the first sidewall 111 and the second sidewall 121 enclose the second limiting slot 150. In this embodiment, the first elastic layer 130 is arranged on the side of the first main body layer 110 facing the second plate 200, and can also enclose the second limiting slot 150 with the first main body layer 110 and the stopper 120, with the opening 151 upward. In the process of the first limiting part 221 being clamped into the second limiting slot 150, the first limiting part 221 extrudes the stopper 120, the stopper 120 extrudes the first elastic layer 130, and the first elastic layer 130 is elastically deformed and compressed, so that the stopper 120 can be offset outwardly following the deformation of the first elastic layer 130, and the opening 151 of the second limiting slot 150 is increased. With the stopper 120 being offset outwardly, the first limiting part 221 is gradually embedded into the second limiting slot 150, and the second limiting part 222 is also gradually embedded into the first limiting slot 140, the downward pressure of the first limiting part 221 on the stopper 120 is reduced to disappear, the shape of the first elastic layer 130 is restored, the position of the stopper 120 is restored, and the connection and locking of the first plate 100 and the second plate 200 are realized.

[0076] Please refer to Figure 11 and Figure 12 In some embodiments, the first main body layer 110 further has a fitting slot 160 arranged below the first limiting slot 140, and the first elastic layer 130 is embedded in the fitting slot 160 and extends below the stopper 120 towards the second plate 200. Optionally, as shown in Figure 11 , the fitting slot 160 can be formed on the lower edge of the first main body layer 110 close to the second plate 200, and the first elastic layer 130 is embedded in the fitting slot 160, so that the first upper surface 131 and the side end face of the first elastic layer 130 can be connected to the first main body layer 110, thereby ensuring the connection strength. As shown in Figure 12 , in some embodiments, the fitting slot 160 is formed at one end of the first main body layer 110 close to the second plate 200, and the slot opening of the fitting slot 160 is arranged on the first sidewall 111. By embedding one end of the first elastic layer 130 in the fitting slot 160, the connection strength with the first main body layer 110 can be further improved. Optionally, the fitting slot 160 can adopt the structure of a dovetail slot.

[0077] Optionally, in Figure 11And Figure 12 In the embodiment shown, the first elastic layer 130 can be arranged in a hinged (rotatable) manner at the connection with the first main body layer 110. When the first main body layer 110 is lifted upward, the first elastic layer 130 rotates downward due to gravity, so that the opening 151 of the second limiting groove 150 increases in angle, and the first limiting part 221 is smoothly inserted into the second limiting groove 150. After the first plate 100 is placed on the ground, the first elastic layer 130 is reset due to the support of the ground, realizing the connection and locking of the first plate 100 and the second plate 200.

[0078] Please refer again to Figures 1 to 3 In some embodiments, in the thickness direction Z of the first plate 100, the first limiting groove 140 is located above the second limiting groove 150. Therefore, in the process of connecting the second plate 200 with the first plate 100, after the second limiting part 222 is inserted into the first limiting groove 140, the second limiting part 222 can serve as a fulcrum, and by rotating the second plate 200 around the second limiting part 222, the first limiting part 221 can be more smoothly inserted into the second limiting groove 150, and the second limiting part 222 can be more smoothly inserted into the first limiting groove 140.

[0079] Please refer to Figure 5 In some embodiments, the second plate 200 further comprises a second main body layer 210, and the edge structure 220 is connected to the second main body layer 210 near the side close to the first plate 100, and the second main body layer 210 and the first limiting part 221 have a third groove 240 therebetween. In the case where the first limiting part 221 is inserted into the second limiting groove 150, the stop block 120 is inserted into the third groove 240. That is, the third groove 240 is a relief groove arranged between the second main body layer 210 and the first limiting part 221, and when the second plate 200 and the first plate 100 are connected, the stop block 120 is located between the first limiting part 221 and the second main body layer 210. By arranging the third groove 240, the stop block 120 can be avoided, so that there is enough space to accommodate the stop block 120, and thus the stop block 120 can be made higher. Moreover, by arranging the third groove 240, the assembled first plate 100 and second plate 200 can be made more flat, improving the user experience.

[0080] Specifically, as Figure 5 shown, the second limiting part 222 has a third side wall 223, the second main body layer 210 has a fourth side wall 211 opposite the third side wall 223, and the edge structure 220 further comprises a connecting surface 224 connected between the third side wall 223 and the fourth side wall 211, and the connecting surface 224, the third side wall 223 and the fourth side wall 211 form the third groove 240.

Controlling the included angle α within the above range can improve the interlocking effect of the third side wall 223 and the second side wall 121, and further improve the transverse connection strength between the first plate 100 and the second plate 200. Within the above range, when the included angle α approaches 90°, the transverse connection strength is greater, and the right angle surface is easier to process, and the processing difficulty is lower; when the included angle α approaches 100°, the first limiting portion 221 is more easily embedded in the second limiting groove 150, and it is relatively easier to assemble. Alternatively, the included angle α can be any angle value and a range value between any two angle values in 90°, 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99°, and 100°.
