[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: like Figure 1-8 As shown, a hidden wall bed support mechanism proposed in one embodiment of the present invention includes a flipping assist mechanism 3. The flipping assist mechanism 3 includes an inner mounting plate 31. A rotary drive plate 32 is movably disposed on one side of the inner mounting plate 31. A rotary shaft 33 is internally connected to the rotary drive plate 32. A bidirectional gas spring 34 is movably disposed on one side of the inner mounting plate 31, and the end of the bidirectional gas spring 34 away from the inner mounting plate 31 is movably connected to one end of the rotary drive plate 32.

[0023] like Figure 1-8As shown, in some embodiments, the rotary drive plate 32 is provided with at least one torque transmission groove 321 inside, and the surface of the rotary shaft 33 is provided with torque transmission pins 331 that are the same number as the torque transmission grooves 321 and are fitted one-to-one.

[0024] When the rotating shaft 33 rotates, it drives the torque transmission groove 321 to rotate synchronously through the torque transmission pin 331. The torque transmission groove 321 drives the rotating drive plate 32 to rotate, realizing the synchronous rotation between the rotating shaft 33 and the rotating drive plate 32. The rotating shaft 33 and the rotating drive plate 32 are driven by the torque transmission pin 331 and the torque transmission groove 321, which facilitates production assembly and subsequent inspection and maintenance.

[0025] like Figure 1-8 As shown, in some embodiments, an outer mounting plate 35 is fixedly disposed on one side of the inner mounting plate 31, and one end of the rotating shaft 33 extends into the interior of the outer mounting plate 35.

[0026] The outer mounting plate 35 and the inner mounting plate 31 work together to support the rotating shaft 33, ensuring the stability of the rotating shaft 33.

[0027] like Figure 1-8 As shown, in some embodiments, both the outer mounting plate 35 and the inner mounting plate 31 are provided with mounting plate bushings 36, and the mounting plate bushings 36 are fitted with open copper sleeves 37. The rotating shaft 33 is movably connected to the inner mounting plate 31 and the outer mounting plate 35 through the open copper sleeves 37.

[0028] The outer mounting plate 35 and the inner mounting plate 31 are in contact with the rotating shaft 33 by means of mounting plate bushing 36 and open copper bushing 37, which ensures the stability of the rotating shaft 33 during rotation and prevents jamming.

[0029] like Figure 1-8 As shown, in some embodiments, one end of the outer mounting plate 35 is fixedly connected to the inner mounting plate 31 via a mounting plate positioning pin 311, and the other end is fixedly connected to the inner mounting plate 31 via a mounting plate connecting post 312. One end of the mounting plate connecting post 312 extends to one side of the inner mounting plate 31 and is provided with a connecting post positioning sleeve 313.

[0030] The mounting plate connecting column 312 can not only connect and fix the external mounting plate 35 and the internal mounting plate 31, but also limit and support the rotary drive plate 32, thereby improving the stability of the bed frame 2 in the closed state.

[0031] like Figure 1-8As shown, in some embodiments, a boss 38 is provided on one side of the inner mounting plate 31, and the end of the bidirectional gas spring 34 away from the rotary drive plate 32 is movably hinged to one side of the boss 38. The bidirectional gas spring 34 includes a first gas spring 341 and a second gas spring 342.

[0032] The bidirectional gas spring 34 provides assistance for the bed frame 2 when it is tilted up and cushions it when it is tilted down, making the process of closing and using the bed frame 2 easier and allowing for single-person operation. When tilting the bed frame 2 up, the first gas spring 341 and the second gas spring 342 extend to lift the bed frame 2 to provide assistance. When the bed frame 2 is nearly fully closed, the second gas spring 342 loses its supporting force due to the through-track groove 42 set on the rotating plate 4, thus reducing the supporting force on the bed frame 2 and preventing the bed frame 2 from impacting the cabinet 1. At the same time, when the bed frame 2 is fully closed inside the cabinet 1, the first gas spring 341 continues to hold the bed frame 2, ensuring stability in the closed state. When tilting the bed frame 2 down, the opposite is true (the second gas spring 342 provides support for a delayed time due to the through-track groove 42 set on the rotating plate 4, making opening easier). The first gas spring 341 and the second gas spring 342 retract at a staggered and uniform speed, causing the bed frame 2 to descend slowly, improving safety.

[0033] like Figure 1-8 As shown, in some embodiments, the surface of the rotating shaft 33 is further fitted with an isolation sleeve 39 located between the rotating drive plate 32 and the mounting plate bushing 36, and the interior of the rotating shaft 33 is provided with a transmission hole 332.

[0034] The shape of the transmission hole 332 matches the shape of the transmission shaft 22. It can be a combination of a circle and a spline, or it can be a polygonal design for direct transmission. The isolation sleeve 39 separates the rotary drive plate 32 and the mounting plate bushing 36 to reduce wear.

[0035] A wall bed includes a bed cabinet 1, a bed frame 2, and a concealed wall bed support mechanism. The flip-up assist mechanism 3 is disposed inside both sides of the bed cabinet 1, and the bed frame 2 is rotatably connected to the bed cabinet 1 through the flip-up assist mechanism 3.

[0036] like Figure 1-8 As shown, in some embodiments, bed frame fasteners 21 are provided on both sides of the bed frame 2. The bed frame fasteners 21 include a bed frame drive plate 211 and a bed frame reinforcing plate 212. The bed frame drive plate 211 and the bed frame reinforcing plate 212 are arranged opposite to each other on both sides of the bed frame 23. The bed frame drive plate 211 and the bed frame reinforcing plate 212 are fastened together by screws 213. Washers 214 and spring washers 215 are fitted on the screws 213. Both sides of the bed frame 2 have clearance holes 24 inside the bed side 23. A drive shaft 22 is fixedly installed inside the bed frame drive plate 211. One end of the drive shaft 22 passes through the clearance hole 24 and the bed frame reinforcing plate 212 in sequence and is inserted into the drive hole 332 and connected to it for transmission. The bed cabinet 1 has decorative panels 11 and side panels 12 on both sides. The flipping assist mechanism 3 is located between the decorative panels 11 and the side panels 12. The inner mounting plate 31 is fixed to one side of the decorative panel 11.

[0037] The combination of screw 213, washer 214, and spring washer 215 reduces the transmission of rigid vibration between the bed frame drive plate 211 and the bed frame 2's bed side 23, reducing damage to the bed frame 2. The bed frame drive plate 211 and bed frame reinforcing plate 212 are sandwiched on both sides of the bed side 23, increasing the support area and improving support stability. The setting of the clearance hole 24 allows the drive shaft 22 to pass through the bed side 23, the bed frame drive plate 211, and the bed frame reinforcing plate 212, making the torque of the drive shaft 22 more effectively transmitted to the bed frame 2. The decorative plate 11 and side plate 12, as part of the bed cabinet 1, are used to install the flipping assist mechanism 3, and can also cover the flipping assist mechanism 3, improving the overall integrity and appearance of the flipping bed.

[0038] Example 2: like Figure 1-12 As shown, a hidden wall bed support mechanism proposed in one embodiment of the present invention includes a flipping assist mechanism 3. The flipping assist mechanism 3 includes an inner mounting plate 31. A rotary drive plate 32 is movably disposed on one side of the inner mounting plate 31. A rotary shaft 33 is internally connected to the rotary drive plate 32. A bidirectional gas spring 34 is movably disposed on one side of the inner mounting plate 31, and the end of the bidirectional gas spring 34 away from the inner mounting plate 31 is movably connected to one end of the rotary drive plate 32.

[0039] like Figure 1-12 As shown, in some embodiments, the rotary drive plate 32 is provided with at least one torque transmission groove 321 inside, and the surface of the rotary shaft 33 is provided with torque transmission pins 331 that are the same number as the torque transmission grooves 321 and are fitted one-to-one.

[0040] When the rotating shaft 33 rotates, it drives the torque transmission groove 321 to rotate synchronously through the torque transmission pin 331. The torque transmission groove 321 drives the rotating drive plate 32 to rotate, realizing the synchronous rotation between the rotating shaft 33 and the rotating drive plate 32. The rotating shaft 33 and the rotating drive plate 32 are driven by the torque transmission pin 331 and the torque transmission groove 321, which facilitates production assembly and subsequent inspection and maintenance.

[0041] like Figure 1-12As shown, in some embodiments, an outer mounting plate 35 is fixedly disposed on one side of the inner mounting plate 31, and one end of the rotating shaft 33 extends into the interior of the outer mounting plate 35.

[0042] The outer mounting plate 35 and the inner mounting plate 31 work together to support the rotating shaft 33, ensuring the stability of the rotating shaft 33.

[0043] like Figure 1-12 As shown, in some embodiments, both the outer mounting plate 35 and the inner mounting plate 31 are provided with mounting plate bushings 36, and the mounting plate bushings 36 are fitted with open copper sleeves 37. The rotating shaft 33 is movably connected to the inner mounting plate 31 and the outer mounting plate 35 through the open copper sleeves 37.

[0044] The outer mounting plate 35 and the inner mounting plate 31 are in contact with the rotating shaft 33 by means of mounting plate bushing 36 and open copper bushing 37, which ensures the stability of the rotating shaft 33 during rotation and prevents jamming.

[0045] like Figure 1-12 As shown, in some embodiments, one end of the outer mounting plate 35 is fixedly connected to the inner mounting plate 31 via a mounting plate positioning pin 311, and the other end is fixedly connected to the inner mounting plate 31 via a mounting plate connecting post 312. One end of the mounting plate connecting post 312 extends to one side of the inner mounting plate 31 and is provided with a connecting post positioning sleeve 313.

[0046] The mounting plate connecting column 312 can not only connect and fix the external mounting plate 35 and the internal mounting plate 31, but also limit and support the rotary drive plate 32, thereby improving the stability of the bed frame 2 in the closed state.

[0047] like Figure 1-12 As shown, in some embodiments, the bidirectional gas spring 34 includes a first gas spring 341 and a second gas spring 342.

[0048] The bidirectional gas spring 34 provides assistance for the bed frame 2 when it is tilted up and cushions it when it is tilted down, making the process of closing and using the bed frame 2 easier and allowing for single-person operation. When tilting the bed frame 2 up, the first gas spring 341 and the second gas spring 342 extend to lift the bed frame 2 to provide assistance. When the bed frame 2 is nearly fully closed, the second gas spring 342 loses its supporting force due to the through-track groove 42 set on the rotating plate 4, thus reducing the supporting force on the bed frame 2 and preventing the bed frame 2 from impacting the cabinet 1. At the same time, when the bed frame 2 is fully closed inside the cabinet 1, the first gas spring 341 continues to hold the bed frame 2, ensuring stability in the closed state. When tilting the bed frame 2 down, the opposite is true (the second gas spring 342 provides support for a delayed time due to the through-track groove 42 set on the rotating plate 4, making opening easier). The first gas spring 341 and the second gas spring 342 retract at a staggered and uniform speed, causing the bed frame 2 to descend slowly, improving safety.

[0049] like Figure 1-12 As shown, in some embodiments, a rotating plate 4 and a runway rivet 5 are also included. The rotating plate 4 is rotatably mounted on one side of the inner mounting plate 31 via a runway positioning pin 41. The interior of the rotating plate 4 is provided with a runway groove 42. One end of the runway rivet 5 is fixed to the inner mounting plate 31, and the other end extends into the interior of the runway groove 42. The end of the first gas spring 341 away from the rotating drive plate 32 is hinged to one side of the rotating plate 4 and is coaxially arranged with the runway positioning pin 41. The end of the second gas spring 342 away from the rotating drive plate 32 is eccentrically hinged to one side of the rotating plate 4.

[0050] Compared to the design in Embodiment 1 that uses a boss 38 structure to install the first gas spring 341 and the second gas spring 342, this embodiment uses a rotating plate 4 to install the first gas spring 341 and the second gas spring 342. This design can be adapted to larger bed frames 2 and bed frames 2 that require greater support.

[0051] The support requirements for the wall bed at various approximate opening and closing angles: The minimum support force is required from the fully closed state (0 degrees) to the open state (approximately 25 degrees). Simply keeping the bed frame 2 closed and preventing it from opening automatically makes opening easy. As the opening angle increases until it reaches 90 degrees, the horizontal distance between the center of gravity and the rotation point also increases accordingly. Greater support force is needed to prevent the bed frame 2 from rapidly falling. This is achieved by using a two-way gas spring 34 with different support forces at each end. Generally, the smaller spring force is one-third to one-half of the larger spring force, depending on the situation. During the opening action, the section with the smaller spring force is compressed first, or the section of the rotating plate 4 not restricted by the raceway rivet 5 is used, causing the second gas spring 342 to lack a support point and thus fail to provide support force. This continues until the rotating plate 4 is restricted by the raceway rivet 5, causing the second gas spring 342 to rotate and begin providing a smaller support force, which is then superimposed on the support force of the first gas spring 341. Finally, the combined large support forces of the first gas spring 341 and the second gas spring 342 complete the opening to 90 degrees.

[0052] The maximum support force is required when closing from the fully open state (90 degrees) to approximately 45 degrees. Initially, the rotating plate 4 is restricted from rotating by the track rivets 5, so the first gas spring 341 and the second gas spring 342 are in a compressed state. The end with the greatest support force will pop out first. At this time, when an external force is applied to lift the bed, the double-acting gas springs 34 superimpose to provide the maximum support force. At this time, the required external force to lift is the minimum. As the closing angle decreases to approximately 40 degrees, the horizontal distance between the center of gravity and the rotation point also decreases accordingly. The required support force is gradually reduced to prevent the bed frame 2 from rapidly impacting the bed cabinet 1. At this time, the end with the greatest elasticity of the double-acting gas springs 34 extends completely one after another. As the closing continues, the two smaller elastic segments superimpose to provide less support force than before until the smaller elasticity of the second gas spring 342 also extends completely, driving the rotating plate 4 to move in the opposite direction from the opening state. The stroke is less than the required support force, and the smaller elasticity of the first gas spring 341 always provides appropriate elasticity to complete the closing and maintain the bed in a closed state without external force.

[0053] During the downward movement of the bed frame 2, the second gas spring 342 simultaneously drives the rotating plate 4 to swing during its retraction. After the bed frame 2 is in the downward position, the first gas spring 341 and the second gas spring 342 retract to support the bed frame 2. At the same time, as the rotating plate 4 swings, one end of the through-track groove 42 of the rotating plate 4 abuts against the track rivet 5, preventing the rotating plate 4 from swinging further. The through-track groove 42 inside the rotating plate 4, together with the track rivet 5, can limit the swing stroke of the rotating plate 4 with the bed frame 2, thereby improving the stability of the bed frame 2 in both the closed and open states.

[0054] like Figure 1-12 As shown, in some embodiments, the surface of the rotating shaft 33 is further fitted with an isolation sleeve 39 located between the rotating drive plate 32 and the mounting plate bushing 36, and the interior of the rotating shaft 33 is provided with a transmission hole 332.

[0055] The shape of the transmission hole 332 matches the shape of the transmission shaft 22. It can be a combination of a circle and a spline, or it can be a polygonal design for direct transmission. The isolation sleeve 39 separates the rotary drive plate 32 and the mounting plate bushing 36 to reduce wear.

[0056] A wall bed includes a bed cabinet 1, a bed frame 2, and a concealed wall bed support mechanism. The flip-up assist mechanism 3 is disposed inside both sides of the bed cabinet 1, and the bed frame 2 is rotatably connected to the bed cabinet 1 through the flip-up assist mechanism 3.

[0057] like Figure 1-12 As shown, in some embodiments, bed frame fasteners 21 are provided on both sides of the bed frame 2. The bed frame fasteners 21 include a bed frame drive plate 211 and a bed frame reinforcing plate 212. The bed frame drive plate 211 and the bed frame reinforcing plate 212 are arranged opposite to each other on both sides of the bed frame 23. The bed frame drive plate 211 and the bed frame reinforcing plate 212 are fastened together by screws 213. Washers 214 and spring washers 215 are fitted on the screws 213. Both sides of the bed frame 2 have clearance holes 24 inside the bed side 23. A drive shaft 22 is fixedly installed inside the bed frame drive plate 211. One end of the drive shaft 22 passes through the clearance hole 24 and the bed frame reinforcing plate 212 in sequence and is inserted into the drive hole 332 and connected to it for transmission. The bed cabinet 1 has decorative panels 11 and side panels 12 on both sides. The flipping assist mechanism 3 is located between the decorative panels 11 and the side panels 12. The inner mounting plate 31 is fixed to one side of the decorative panel 11.

[0058] The combination of screw 213, washer 214, and spring washer 215 reduces the transmission of rigid vibration between the bed frame drive plate 211 and the bed frame 2's bed side 23, reducing damage to the bed frame 2. The bed frame drive plate 211 and bed frame reinforcing plate 212 are sandwiched on both sides of the bed side 23, increasing the support area and improving support stability. The setting of the clearance hole 24 allows the drive shaft 22 to pass through the bed side 23, the bed frame drive plate 211, and the bed frame reinforcing plate 212, making the torque of the drive shaft 22 more effectively transmitted to the bed frame 2. The decorative plate 11 and side plate 12, as part of the bed cabinet 1, are used to install the flipping assist mechanism 3, and can also cover the flipping assist mechanism 3, improving the overall integrity and appearance of the flipping bed.

[0059] Example 3: like Figure 1-14As shown in the figure, a concealed wall bed support mechanism proposed in one embodiment of the present invention includes a bed turning assist mechanism 6. The bed turning assist mechanism 6 includes a bed cabinet mounting plate 61, an assist arm 62, and a bed frame reinforcement member 66. The bed frame reinforcement member 66 is provided with a rotary drive shaft 65, one end of which passes through the bed cabinet mounting plate 61 and extends into the interior of the assist arm 62. The end of the assist arm 62 away from the rotary drive shaft 65 is movably connected to one end of the bed cabinet mounting plate 61 through a buffer damper 63 and an assist gas spring 64.

[0060] like Figure 1-14 As shown, in some embodiments, a wear-resistant sleeve 68 is provided inside one end of the bed cabinet mounting plate 61, a drive sleeve 67 is provided inside one end of the assist arm 62, and a limit screw 69 is installed at the end of the rotary drive shaft 65 away from the bed reinforcement 66 after passing through the wear-resistant sleeve 68 and the drive sleeve 67 in sequence.

[0061] Compared to Embodiment 1 and Embodiment 2 above, the turning assist mechanism 6 in this embodiment can directly replace the flipping assist mechanism 3, and the structure is more streamlined.

[0062] The bed cabinet mounting plate 61 replaces the inner mounting plate 31 and is fixed to one side of the decorative panel 11; the resistance arm replaces the rotary drive plate 32; the rotary drive shaft 65 replaces the transmission shaft 22; the bed frame reinforcement 66 replaces the bed frame 2 fixing parts; the wear-resistant sleeve 68 replaces the mounting plate bushing 36 and the open copper sleeve 37; the buffer damping 63 and the power-assisted gas spring 64 replace the bidirectional gas spring 34.

[0063] The buffer damper 63 and the assist gas spring 64 provide assistance for the bed frame 2 to flip up and buffer it to flip down, making the process of closing the bed frame 2 and using the bed frame 2 easier and can be operated by a single person. When flipping the bed frame 2 up, the assist gas spring 64 extends to lift the bed frame 2 to provide assistance. When flipping the bed frame 2 down, the buffer damper 63 and the assist gas spring 64 retract at a constant speed, so that the bed frame 2 descends slowly, improving the safety of use.

[0064] In summary, through the ingenious cooperation between the bidirectional gas spring 34 and the rotating plate, the system automatically adapts to the dynamic support requirements at different angles during the opening and closing of the wall bed. It provides minimal support during the initial opening phase to ensure easy start-up, and automatically increases the gas spring support as the opening angle increases, effectively preventing the bed frame 2 from falling rapidly. During closing, the bidirectional gas spring 34 applies force in stages, first providing strong support during the maximum force phase to make closing effortless, then gradually reducing the support force to achieve a smooth and gentle descent, ultimately maintaining a stable closed state. This significantly improves the smoothness and safety of the opening and closing operation, completely avoiding the risk of impact to the bed frame 2, and achieving a perfect balance between effortless operation and safety protection.
