[0029] See Figure 1 , Figure 5 and Figure 7 This utility model embodiment provides a detachable flip-up sofa bed, including: a first sofa bed body 1, a second sofa bed body 2, a back panel 3, and a soft-padded backrest 4; The bottom of the back panel 3 is installed on the rear side of the first sofa bed 1; The upholstered backrest 4 can be detachably placed on the first sofa bed 1 and rests against the back panel 3; One side of the second sofa bed 2 is hinged to the front side of the first sofa bed 1; When the second sofa bed 2 is flipped over to the rear with one side as its axis of rotation, it is stacked on the first sofa bed 1 and combined with the upholstered backrest 4 to form a sofa shape; when the second sofa bed 2 is flipped over to the front with one side as its axis of rotation, it is laid flat parallel to the first sofa bed 1 and forms a bed shape.

[0030] In this embodiment, the core structure of the detachable flip-up sofa bed consists of a first sofa bed body 1, a second sofa bed body 2, a back panel 3, and a padded backrest 4. The bottom of the back panel 3 is fixedly installed on the rear side of the frame of the first sofa bed body 1, serving as the rigid foundation for the entire backrest area. The padded backrest 4 is filled with high-elasticity sponge, and its bottom can be freely placed on the seat surface of the first sofa bed body 1, leaning back against the front side of the back panel 3 (i.e., the side facing the first sofa bed body 1). One side of the second sofa bed body 2 is rotatably connected to the upper front edge of the frame of the first sofa bed body 1 via a set of continuous hinges, allowing the second sofa bed body 2 to rotate around this hinged side as an axis. When a sofa configuration is desired, the second sofa bed body 2 is flipped backward (i.e., towards the back panel 3), stacking itself on top of the first sofa bed body 1; at this time, the padded backrest 4 placed between them and the stacked second sofa bed body 2 together form a complete sofa with a suitable backrest height and seat depth. When a bed-like configuration is required, the second sofa bed 2 is flipped forward (away from the back panel 3) until the second sofa bed 2 and the first sofa bed 1 are at the same level. The two are then joined side by side to form a continuous and spacious sleeping surface.

[0031] Based on this, this embodiment achieves the switching between two main usage modes directly through a simple flipping action, combined with the removable and stackable nature of the upholstered backrest 4. The mode conversion process is extremely intuitive and effortless, eliminating the need for users to move large items or operate complex latches. It is particularly suitable for rapidly changing scenarios in homes with limited space, greatly enhancing the functional flexibility and ease of use of the furniture.

[0032] Combination Figure 2 As shown, in some embodiments, the upholstered backrest 4 can be multiple backrests placed side-by-side along the long side of the second sofa bed 2, or it can be a single, integrated upholstered backrest 4 design, depending on actual needs and design preferences. In bed mode, the upholstered backrest 4 can be removed to free up complete bed space, or it can be left on the bed as a backrest pillow, providing users with a diverse user experience. This design fully considers the needs of users in different scenarios, easily achieving whether a complete bed space is needed for rest or a certain amount of back support is desired in bed mode.

[0033] In one embodiment, the second sofa bed 2 is provided with support portions 21 at both ends; when the second sofa bed 2 is in sofa mode, the support portions 21 are configured as armrest supports; when the second sofa bed 2 is in bed mode, the support portions 21 are configured as bed seat supports.

[0034] In this embodiment, each of the left and right ends of the second sofa bed 2 has an integrally formed or fixedly connected outward and slightly upward extending support portion 21. This support portion 21 is made of solid wood or metal with a sponge covering, providing sufficient load-bearing strength. When the second sofa bed 2 is flipped backward into sofa mode, these two support portions 21 are located on the left and right sides of the combined seat surface, with their top height suitable for supporting elbows, naturally acting as armrests and providing a sense of lateral support and enclosure. When the second sofa bed 2 is flipped forward into bed mode, the support portions 21 descend with the second sofa bed 2, serving as supports on both sides of the second sofa bed 2 after it is fully unfolded, and sharing the overall weight with the legs 11 of the first sofa bed 1, ensuring the stability of the bed mode without wobbling. More specifically, a pad is provided on the support part 21; this pad can be fixed to the support part 21 by screws or adhesive. The pad is made of wear-resistant rubber or high-density plastic. When the second sofa bed 2 is in bed mode, the pad is configured to support the second sofa bed and lift the support part 21 off the ground. That is, when the support part 21 is in contact with the ground as a bed leg, the bottom surface of the pad is actually in contact with the ground first. The design height of the pad is calculated so that the main frame of the support part 21 is slightly off the ground with the support of the pad.

[0035] Based on this, this embodiment assigns a dual-function role to the lateral structural components of the second sofa bed 2. Its posture changes as the main body flips, and its function adapts accordingly. This eliminates the need for additional installation or disassembly of separate armrests or bed legs, simplifying the overall structure, reducing costs, and ensuring necessary support in both configurations, thus achieving a balance between structural efficiency and functional integrity.

[0036] In one embodiment, the detachable flip-up sofa bed further includes a multi-functional upholstery 5; when the second sofa bed body 2 is in sofa mode, the multi-functional upholstery 5 is configured as an armrest upholstery detachably installed on the support part 21; when the second sofa bed body 2 is in bed mode, the multi-functional upholstery 5 is configured as a pillow.

[0037] In this embodiment, the detachable flip-up sofa bed can be configured with two independent multi-functional soft pads 5. Each multi-functional soft pad 5 is filled with soft memory foam and covered with a removable and washable fabric. In sofa mode, the user can attach these two multi-functional soft pads 5 to the upper surface of the support parts 21 at both ends of the second sofa bed 2 via connectors (such as Velcro). At this time, the multi-functional soft pads 5 serve as armrest pads, covering the hard support parts 21, providing a soft and comfortable support surface for the user's arms, improving the sofa's seating comfort and aesthetics. When converted to bed mode, the user can remove the multi-functional soft pads 5 from the support parts 21 and place them horizontally or vertically in the headboard area of ​​the assembled bed, where they serve as pillows for sleeping, providing head support.

[0038] Based on this, the movable multi-functional upholstered cushion 5 can be used to match different usage needs (armrests or pillows) according to different body shapes (sofa or bed). In this way, the multi-functional upholstered cushion 5 accessories are reused in different scenarios, which significantly enhances the product's functionality and user experience. Users do not need to prepare pillows separately for their beds, realizing the economy and convenience of "one set of accessories, two uses".

[0039] In one embodiment, the bottom surface of the multifunctional soft bag 5 is provided with a first joint portion, and the support portion 21 is provided with a second joint portion 211; the first joint portion and the second joint portion 211 are detachably connected to each other.

[0040] In this embodiment, to achieve a stable and detachable connection of the multifunctional soft bag 5 to the support portion 21, the specific structure is as follows: A rectangular first joint is sewn or fixed to the bottom surface of each multifunctional soft bag 5. For example, the first joint is a piece of high-strength hook-and-loop fastener webbing. Correspondingly, on the upper surface of each support portion 21, at the position corresponding to the first joint, a matching second joint 211, i.e., a piece of loop fastener webbing, is provided. When it is necessary to install the multifunctional soft bag 5, simply align and press the first joint (hook side) at its bottom onto the second joint 211 (loop side) of the support portion 21. The two will then generate a strong adhesive force through the hook-and-loop fastener principle, achieving a firm connection. During disassembly, only a peeling force is required to separate them.

[0041] Furthermore, the specific detachable connection between the first joint and the second joint 211 can be selected in several ways. For example, the detachable connection between the first joint and the second joint 211 can be one of Velcro, zipper, or snap fastener. As mentioned above, the Velcro method is achieved by combining the hook side and the loop side. The second type is the zipper type, in which case the first joint can be a zipper tooth (male or female) sewn onto the bottom of the multifunctional soft bag 5, and the second joint 211 is a corresponding tooth sewn or fixed onto the support part 21, and the connection is achieved by opening and closing the zipper pull. The third type is the snap fastener type, such as a snap button, in which the first joint is a raised male snap button sewn onto the bottom of the soft bag, and the second joint 211 is a recessed female snap button embedded in the surface of the support part 21, and the engagement is achieved by pressing.

[0042] Combination Figure 3 and Figure 4 In one embodiment, the bottom of the first sofa bed body 1 is provided with a plurality of foot posts 11.

[0043] In this embodiment, six support posts 11 are installed on the bottom frame of the first sofa bed 1, below the four corners and the central load-bearing beam. These support posts 11 can be made of metal tubes or solid wood blocks and are vertically fixed to the bed frame by flanges or direct screws. The bottom of the support posts 11 is usually fitted with rubber anti-slip pads 212. They evenly bear the entire weight of the first sofa bed 1 and transfer it to the ground.

[0044] In one embodiment, the leg post 11 located at the rear of the first sofa bed 1 is simultaneously fixed to the bottom of the first sofa bed 1 and the bottom of the back panel 3.

[0045] In this embodiment, the two rear legs 11 of the first sofa bed 1 not only support the bed in the vertical direction but also serve as crucial structural connections in the horizontal direction. Specifically, each rear leg 11 is simultaneously fixed to the rear crossbeam at the bottom of the first sofa bed 1 and the underside of the back panel 3 via a set of connectors (such as multiple screws). This makes the leg 11 part of a rigid triangular support node connecting the first sofa bed 1 and the back panel 3.

[0046] Based on this, this embodiment utilizes the support column 11 to simultaneously bear the dual functions of vertical load transfer and lateral structural connection. This greatly enhances the connection rigidity and integrity between the back panel 3 and the first sofa bed body 1. When the user leans against the back panel 3, the force can be directly transferred through this reinforced path (back panel 3 -> column 11 -> ground), effectively preventing twisting, abnormal noise, or even loosening at the connection between the back panel 3 and the first sofa bed body 1, significantly improving the structural reliability and safety of the product during long-term use.

[0047] In one embodiment, the bottom of the first sofa bed 1 is further provided with at least one reinforcing column 12; the reinforcing column 12 is fixed to both the bottom of the first sofa bed 1 and the bottom of the back panel 3.

[0048] In this embodiment, to enhance the connection strength between the first sofa bed body 1 and the back panel 3, at least one reinforcing post 12 is provided at the bottom of the first sofa bed body 1. This reinforcing post 12 is an independent block-shaped or short column-shaped structure, which can be made of solid wood, metal, or high-strength engineering plastic. Specifically, fasteners such as screws or bolts can be used to fix the connection through the reinforcing post 12, the bottom of the first sofa bed body 1, and the back panel. In this way, the reinforcing post 12 itself acts as a rigid connecting block, firmly locked to the first sofa bed body 1 and the back panel 3 by mechanical fasteners, forming an additional, direct physical connection and preventing loosening at the connection point after long-term use.

[0049] In one embodiment, the second joint 211 is detachably mounted on the support 21.

[0050] In this embodiment, the second joint 211 provided on the support 21 is detachably mounted on the support 21. Specifically, the second joint 211 (such as a Velcro webbing, a zipper strap, or a snap fastener) can first be fixed to a separate base or pad, and then the base or pad can be detachably covered or connected to the outer surface of the support 21 by means of, for example, a zipper, Velcro, or snap fastener. This design allows the entire module, including the second joint 211 and its surrounding support members, to be removed from the support 21 (e.g., ...). Figure 6 (The area marked by the dashed line).

[0051] Based on this, the easily soiled and damaged second joint 211 can be designed as an independently detachable module. This offers two advantages: first, it facilitates cleaning and maintenance; when the second joint 211 and its associated module become soiled due to its proximity to the ground, they can be removed for cleaning, maintaining product hygiene; second, it facilitates replacement and repair; when the second joint 211 fails due to wear and tear from long-term use (such as decreased Velcro adhesion or damaged zippers), users can replace this module individually at low cost, without needing to address the entire support section 21 or the sofa bed body, greatly improving the product's maintainability, lifespan, and economy.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
