Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a modular massage sofa. Background Technology

[0002] As modern living spaces become increasingly compact, multifunctional furniture is gaining popularity. Among them, modular sofas, especially sofa beds that can be transformed into beds, are widely used because they effectively save space and meet the needs of users for temporary rest in small spaces such as living rooms or studies.

[0003] To achieve the conversion between a sofa and a bed, existing modular sofas typically require a complex folding or pulling mechanism. These mechanisms often have design limitations. For example, some folding mechanisms are structurally complex, containing multiple linkages and hinge points, requiring considerable force from the user and making the process cumbersome, thus reducing ease of use.

[0004] Furthermore, to ensure structural stability after unfolding into a bed configuration, these folding mechanisms also require corresponding support and locking devices. However, existing support and locking devices often have poor linkage with the folding action or unreliable locking methods. This can not only lead to problems such as shaking and abnormal noises in the unfolded bed, affecting the user's rest experience, but also pose safety hazards due to component wear after long-term use. Therefore, how to simplify the operation of the folding mechanism while ensuring its structural stability in the unfolded state has become an urgent technical problem to be solved in this field.

[0005] Therefore, this utility model proposes a modular massage sofa to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of complex folding mechanism structure, inconvenient operation, and insufficient support stability after unfolding in the existing modular massage sofa, this utility model aims to provide a modular massage sofa with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a modular massage sofa, including a sofa seat and a folding mechanism connected to the sofa seat. The folding mechanism includes an extension module; the folding mechanism also includes an arc-shaped support plate, an arc-shaped support block, a fixing plate, and a guide plate.

[0008] The folding mechanism's motion structure is achieved by the cooperation of the arc-shaped support plate and the arc-shaped support block. One end of the arc-shaped support plate is rotatably connected to the arc-shaped support block via a first rotating shaft. Furthermore, both the arc-shaped support plate and the arc-shaped support block are rotatably connected to the interior of the extension module via a second rotating shaft, forming a folding structure with dual rotating shaft linkage.

[0009] Furthermore, the support and locking structure of the folding mechanism is realized by the fixed plate and its cooperating components. The fixed plate is slidably connected to the folding mechanism through the guide plate, allowing it to move between the support position and the storage position of the extension module. In order to lock the fixed plate, the fixed plate is provided with a support block, and the support block is provided with a locking pin and a locking block. The locking pin is rotatably inserted into the support block and is pluggable and detachable with the locking block. The locking or unlocking of the fixed plate can be completed by rotating and plugging / unplugging the locking pin.

[0010] Preferably, in order to accurately guide the movement trajectory of the arc-shaped support plate, a groove is provided on the inner wall of the extension module, and a guide post is connected to the other end of the arc-shaped support plate away from the first rotating shaft. The end of the guide post is slidably disposed in the groove. The cooperation between the guide post and the groove ensures the stability of the folding and unfolding process.

[0011] Preferably, in order to achieve convenient and reliable locking, the locking block has a slot for the locking pin to pass through. The rod of the locking pin has a non-circular cross-section. When it is rotated to a specific angle, its cross-sectional profile matches the slot to allow passage. In the locked state, its cross-sectional profile is misaligned with the slot to form interference, thereby preventing the locking pin from accidentally coming out.

[0012] Preferably, in order to enhance the overall structural strength and motion stability of the folding mechanism, the arc-shaped support plate is symmetrically provided with arc-shaped support blocks on both sides. This symmetrical layout helps to evenly distribute stress during movement and avoid twisting deformation.

[0013] Preferably, the modular massage sofa also includes a headrest, which is connected to the upper part of the folding mechanism to form a complete sofa shape and provide comfortable neck support for the user.

[0014] Preferably, to facilitate the cleaning and replacement of the backrest, the modular massage sofa further includes a backrest, a fixing block, and a quick-release assembly for fixing the backrest. The fixing block is fixed to the outer wall of the extension module, providing a stable mounting reference for the backrest.

[0015] Preferably, the quick-release assembly includes an adjusting rod, a limiting post, and a spring; the adjusting rod is disposed between the quick-release assemblies, and its movement can drive the limiting post to move axially, thereby pressing the cushion between the limiting post and the fixing block; the spring is sleeved on the outside of the limiting post, and is used to provide elastic force when the adjusting rod is released, actively pushing the limiting post backward, thereby quickly releasing the pressing force on the cushion, making it convenient for the user to take it out and put it away.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a folding mechanism, uses an arc-shaped support plate and an arc-shaped support block linked by a double rotating shaft, and cooperates with a sliding and locking fixing plate to support the extension module. This solves the problems of complex structure, inconvenient operation and insufficient support stability of existing modular furniture technology. It achieves the technical effect of stable and reliable structure and easy and convenient conversion between furniture technology and bed form.

[0017] 2. This utility model, by setting a quick-release component for fixing the cushion, uses a rotating adjustment rod to drive the limiting post to press or release the cushion, and uses a spring to achieve active reset, which solves the problems of cumbersome disassembly and inconvenient cleaning and replacement of furniture cushions in the prior art, and achieves the technical effect of easy and quick disassembly and assembly of cushions, convenient cleaning and maintenance for users and personalized replacement.

[0018] 3. This utility model combines the functions of a folding bed with quick-release cushions, solving the dual problems of insufficient rest facilities in limited spaces and difficulties in daily maintenance of furniture. It achieves the technical effect of improving product integration and ease of use, and meets users' needs for massage and rest in different scenarios. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model 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 utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 5 This utility model provides a modular furniture technology that aims to solve the problems of complex structure of folding mechanism 3 and unstable support after unfolding, as well as difficulty in cleaning and replacing back cushion 404 in the prior art modular furniture technology.

[0023] like Figure 1 As shown, the modular furniture technology includes a sofa seat 1, a headrest 2, and a folding mechanism 3 connected to the sofa seat 1. The headrest 2 is connected to the upper part of the folding mechanism 3, which is used to realize the transformation between the furniture technology form and the bed form. like Figure 2 and Figure 3As shown, the folding mechanism 3 includes an extension module 301, an arc-shaped support plate 302, an arc-shaped support block 306, a fixing plate 307, and a guide plate 311. The motion structure of the folding mechanism 3 is achieved by the cooperation of the arc-shaped support plate 302 and the arc-shaped support block 306. One end of the arc-shaped support plate 302 is rotatably connected to the arc-shaped support block 306 through a first rotating shaft 304. At the same time, both the arc-shaped support plate 302 and the arc-shaped support block 306 are rotatably connected to the inside of the extension module 301 through a second rotating shaft 305. The extension module 301 is driven to move through the combined rotation of the first rotating shaft 304 and the second rotating shaft 305. Folding or unfolding; the support and locking structure of the folding mechanism 3 is realized by the fixed plate 307 and its cooperating parts. The fixed plate 307 is slidably connected to the folding mechanism 3 and is used to abut and support the unfolded extension module 301. The fixed plate 307 is slidably connected through the guide plate 311 and is used to move the fixed plate 307 to the back of the folding mechanism 3 when folding. To ensure the reliability of the support, the fixed plate 307 is provided with a support block 309. The support block 309 is provided with a locking pin 308 and a locking block 310. The locking pin 308 is rotatably inserted in the support block 309 and can be plugged and unplugged into the locking block 310 to lock or unlock the fixed plate 307.

[0024] Please refer to the following carefully. Figure 2 and Figure 3 The folding action of the extension module 301 is achieved by an internal linkage structure, which includes an arc-shaped support plate 302 and arc-shaped support blocks 306 disposed on both sides of the arc-shaped support plate 302. The end of the arc-shaped support plate 302 away from the second rotating shaft 305 is rotatably connected to the corresponding arc-shaped support block 306 via a first rotating shaft 304. Simultaneously, both the arc-shaped support plate 302 and the arc-shaped support blocks 306 are rotatably connected to the inner wall of the extension module 301 via the second rotating shaft 305. The inner wall is also provided with a sliding groove. The other end of the arc-shaped support plate 302 away from the first rotating shaft 304 is connected to a guide post 303. The guide post 303 is slidably disposed in the sliding groove. When the extension module 301 is folded or unfolded, the guide post 303 slides along the sliding groove. At the same time, the arc-shaped support plate 302 and the arc-shaped support block 306 rotate around the second rotating shaft 305 respectively, and rotate around the first rotating shaft 304. This linkage method combining rotation and sliding ensures the smoothness and stability of the extension module 301 during the unfolding process. Please refer to the following carefully. Figure 2 and Figure 3The fixed plate 307 is slidably connected to the folding mechanism 3 via the guide plate 311, allowing the fixed plate 307 to move between the support position below the extension module 301 and the storage position behind the folding mechanism 3. The fixed plate 307 integrates a locking component, which includes a support block 309 fixedly mounted on the fixed plate 307. The support block 309 has a locking block 310, which has a slot for the locking pin 308 to pass through. The locking pin 308 is rotatably mounted in the support block 309. When locking is required, the locking pin 308 passes through the slot of the locking block 310 and rotates at a specific angle, causing the cross-sectional shape of the locking pin 308 to be misaligned with the slot, thus preventing it from being pulled out and achieving reliable locking of the fixed plate 307.

[0025] As a preferred embodiment, to improve the guiding accuracy and stability of the extension module 301's movement, please refer to... Figure 2 The inner wall of the extension module 301 is provided with a sliding groove, and the other end of the arc-shaped support plate 302 away from the first rotating shaft 304 is connected to a guide post 303. The end of the guide post 303 is slidably disposed in the sliding groove, thereby providing precise constraints on the movement trajectory of the arc-shaped support plate 302. As a preferred embodiment, to achieve the quick locking and unlocking function of the locking pin 308, please refer to... Figure 3 The locking pin 308 has a slot for the locking pin 308 to pass through. The rod of the locking pin 308 has a non-circular cross section. When the locking pin 308 is rotated to a specific angle so that its cross section profile matches the slot profile, the locking pin 308 can pass through or disengage smoothly from the slot. In the locked state, the locking pin 308 is rotated to another angle so that its cross section profile is misaligned and interferes with the slot, thereby preventing the locking pin 308 from accidentally coming out. As a preferred embodiment, in order to enhance the overall structural strength and motion stability of the folding mechanism 3, arc-shaped support blocks 306 are symmetrically arranged on both sides of the arc-shaped support plate 302. This symmetrical layout helps to evenly distribute stress during folding and unfolding, and avoids twisting or deformation caused by unilateral force. As a preferred embodiment, this modular furniture technology also includes a headrest 2, which is connected to the upper part of the folding mechanism 3 to form a complete furniture technology form and provide neck support for the user; As a preferred embodiment, for easy cleaning and replacement of the 404 cushion, please refer to... Figure 4 and Figure 5This modular furniture technology also features a quick-release structure, which includes a cushion 404, a fixing block 405, and a quick-release assembly 4 for fixing the cushion 404. The fixing block 405 is fixed to the outer wall of the extension module 301, providing a stable installation reference and support surface for the cushion 404. The quick-release assembly 4 specifically includes an adjusting rod 401 and a limiting post 402. The adjusting rod 401 is located on the main body of the quick-release assembly 4. Through its own movement, it drives the limiting post 402 to move along its axial direction, thereby firmly pressing the cushion 404 between the limiting post 402 and the fixing block 405. To achieve quick release, the quick-release assembly 4 also includes a spring 403. The spring 403 is sleeved on the outside of the limiting post 402. When the adjusting rod 401 is tightened, it is compressed. When the adjusting rod 401 is loosened, the spring 403 releases its elastic force to actively push the limiting post 402 backward, thereby releasing the pressure on the cushion 404 and creating operating space for removing the cushion 404.

[0026] The working principle of this modular furniture technology is as follows: When the furniture needs to be unfolded from its folded state, the user pulls the extension module 301 outward until it is level with the folding mechanism 3. During this process, the arc-shaped support plate 302 and the arc-shaped support block 306 inside the extension module 301 rotate around the second pivot 305. At the same time, the arc-shaped support plate 302 and the arc-shaped support block 306 unfold around the first pivot 304. The guide column 303 slides to both sides along the groove on the inner wall of the extension module 301. When the extension module 301 is fully unfolded, the fixing plate 307 is moved along the guide plate 305. 11. Slide the extension module 301 to the rear to form support, then rotate the locking pin 308 to a specific angle so that it can pass into the slot reserved in the latch 310. After passing into the slot, rotate the locking pin 308 again to make it misalign with the slot, thereby locking the fixing plate 307. At this time, the furniture technology is transformed into a stable bed form. When folding is required, the operation is reversed. First, rotate the locking pin 308 to unlock and remove the fixing plate 307, then push the extension module 301 inward. The internal linkage structure will smoothly fold in with the cooperation of guidance and rotation.

[0027] When the cushion 404 needs to be replaced, first turn the adjusting rod 401 to loosen the quick-release assembly 4. At this time, the compressed spring 403 extends and presses against the limiting post 402. After the limiting post 402 is subjected to force, it pushes the main body of the quick-release assembly 4 outward, releasing the pressure on the cushion 404, and the cushion 404 can be removed. When the cushion 404 needs to be fixed, place the cushion 404 on the support surface of the fixing block 405, and then turn the adjusting rod 401 in the opposite direction. The adjusting rod 401 drives the limiting post 402 to move inward through its own movement, pressing the cushion 404 and fixing it between the quick-release assembly 4 and the fixing block 405. Through the synergistic effect of the adjusting rod 401, the spring 403 and the limiting post 402, this utility model solves the problems of inconvenient cleaning and difficulty in personalized adjustment of the cushion 404 in the prior art.

[0028] 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 variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
