[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figures 1 to 9 The composite panel shown includes a covering member 1 and a frame member 2. Figure 1 and Figure 2 In the embodiment of the present invention, the covering member 1 is a plate structure formed by plastic foaming. The plastic foam here can be made of EPP material. Of course, those skilled in the art can also choose other common materials as needed; the frame member 2 is made of hollow alloy material. The frame member 2 constitutes a closed frame. The hollow alloy material here can be made of aluminum alloy or stainless steel alloy, etc., and is connected to the inner side of the covering member 1. The covering member 1 and / or the frame member 2 have a connecting structure on the surface facing each other, so that the frame member 2 is embedded in the covering member 1. It should be pointed out here that the connecting structure has various structural forms, such as bonding, screwing, riveting, or the frame member 2 can be embedded in the covering member 1 during the foaming process.

[0033] In the above embodiment, the combination of the covering member 1 composed of a plastic foamed plate and the frame member 2 made of a hollow alloy material takes into account both the surface softness and the supporting strength of the plate. At the same time, the combination of the frame member 2 embedded in the covering member 1 also reduces the overall thickness of the combined plate, thereby reducing the overall weight and thickness of the plate, thereby improving the comfort of the sofa while facilitating packaging and transportation.

[0034] In the embodiment of the present invention, there are various corresponding relationships between the number of frame members 2 and covering members 1, which can be a one-to-one or a many-to-one structure, such as Figure 2As shown in FIG, at least one frame member 2 is provided in the covering member 1. When there are two or more frame members 2 in the covering member 1, connecting support members 21 are further provided between adjacent frame members 2. The provision of the connecting support members 21 can increase the overall support of the frame member 2 and improve the supporting strength of the covering member 1.

[0035] In some embodiments of the present invention, Figure 3 As shown in the figure, the outer wall of the covering member 1 is an arcuate structure, the peripheral sides of the inner wall of the covering member 1 are in the same horizontal plane, the inner wall of the covering member 1 is concave outward, and the inner wall of the covering member 1 is also provided with reinforcing ribs 11, which extend in the thickness direction, and the outer wall of the reinforcing ribs 11 constitutes a placement plane 11a for placing the frame member 2. By making the outer surface of the covering member 1 in an arc shape, the overall structural strength of the covering member 1 can be improved, stress concentration can be reduced, and the corners can be protected from harm to the user, thereby improving the comfort of use; the structural strength of the covering member 1 is further strengthened by the provision of the internal reinforcing ribs 11; in the embodiment of the present utility model, the four sides of the inner wall of the covering member 1 refer to the inner side edge positions that are in the same plane, and this plane is parallel to the plane where the outer wall of the reinforcing ribs 11 is located. By setting this structure, the connection and fixation of the frame member 2 can be facilitated.

[0036] In some embodiments of the present invention, the specific connection form between the frame member 2 and the covering member 1 is as follows: Figure 4 As shown in FIG, the connection structure includes a threaded blind hole 31 provided on the reinforcement rib 11 and facing the frame member 2. The frame member 2 has corresponding holes. The frame member 2 and the reinforcement rib 11 are connected by fasteners. Thus, when making the connection, it is only necessary to use fasteners such as screws or bolts to pass through the holes in the frame member 2 and then screw them into the threaded blind hole 31.

[0037] like Figure 5 As shown in the figure, another connection structure of the present invention includes a stepped hole 32 that passes through the reinforcing rib 11 from the outer surface of the covering member 1, and the frame member 2 is provided with a hole position corresponding to the stepped hole 32. The frame member 2 and the covering member 1 are connected by a fastener; the fastener here can be a combination of a bolt and a nut. A reliable connection between the frame member 2 and the covering member 1 is achieved by inserting the bolt into the stepped hole 32 and then passing it through the hole position on the frame member 2, and screwing the nut on the side of the frame member 2. This connection method can provide a plug on the stepped hole 32 to achieve a hidden connection.

[0038] In addition, please refer to Figure 6 and Figure 7A positioning structure is also provided between the cladding member 1 and the frame member 2. The positioning structure includes a positioning groove 41 provided on the side of the reinforcing rib 11 facing the frame member 2, and a positioning protrusion 42 provided on the frame member 2 that matches the positioning groove 41. The positioning structure also includes a positioning groove 43 provided on the frame member 2, and a positioning post 44 provided on the reinforcing rib 11 that corresponds to the positioning groove 43. This type of positioning structure facilitates the positioning and connection of the frame member 2 and the cladding member 1, improves the reliability of the connection, and prevents displacement of the frame member 2 on the cladding member 1 after fixation.

[0039] Please refer to Figure 8 and Figure 2 In some embodiments of the present invention, the structure of the reinforcing rib 11 is further improved. The outer surface of the reinforcing rib 11 further includes a concave fixing groove 11b, the cross-section of which matches the cross-section of the frame member 2. It should be noted that the fixing groove 11b can be directly formed on the reinforcing rib 11 or formed by protrusions between two adjacent reinforcing ribs 11. Furthermore, in the embodiments of the present invention, the fixing groove 11b can be linear or curved, as required.

[0040] Please continue to refer to Figure 2 and Figure 8 In the embodiment of the present invention, the connecting support member 21 passes through the two connected frame members 2 and is fixedly connected to the reinforcing rib 11 at both ends. Figure 2 As shown in , in an embodiment of the present invention, the connecting support member 21 is rod-shaped, and passes through the frame member 2 at both ends and is connected to the reinforcing rib 11. It should be pointed out here that a cover plate or other structural form can be provided. After the connecting support member 21 passes through the frame member 2, the two ends are overlapped on the reinforcing rib 11, and then the connecting support member 21 is fixed by crimping the detachable cover plate provided on the reinforcing rib 11.

[0041] In an embodiment of the present invention, a modular sofa structure is provided, comprising the aforementioned modular panels, the modular panels serving as armrests, and the modular panels being detachable. The modular panels reduce thickness and weight, and the detachable design further reduces the overall volume of the modular sofa, thereby saving transportation costs.
