Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-7 This utility model discloses a linkage mechanism, including: a desk drive rod assembly 51, which includes a desk linkage rod 511 and a desk drive rod 512 rotatably connected to the desk linkage rod 511; a desk fixing assembly 52, which includes a desk fixing member 521 and a desk rotating sleeve 522 rigidly connected to the desk fixing member 521; and a desk rotating assembly 53, which includes a desk rotating plate 531 and a hexagonal rotating shaft 532 rigidly connected to the desk rotating plate 531. When the bed frame 3 is flipped, the linkage mechanism 5 ensures the movement of the desk, keeping the desk surface 7 in a horizontal state. The hexagonal rotating shaft 532 of the desk rotating assembly 53 passes through the desk rotating sleeve 522 of the desk fixing assembly 52 and is fixedly connected to the desk drive rod assembly 51. The other end of the desk drive rod assembly 51 is rotatably connected to the drive rivet 24 on the left and right mounting plate assemblies 23.

[0030] Specifically, both sides of the desk fixing component 521 are provided with adjustment pads 54 located outside the hexagonal rotation shaft 532, and the adjustment pads 54 ensure that the tabletop 7 slides smoothly.

[0031] A flip-up bed with a desk includes a bed cabinet 1, a linkage mechanism 5, and a tabletop 7. The inner walls of the bed cabinet 1 are connected to a bed frame 3 on both sides via an assist mechanism 2. The bed frame 3 has a tabletop 7 on both sides via the linkage mechanism 5. The assist mechanism 2 includes a gas spring 21, a damper 22, and mounting plate assemblies 23 arranged on the left and right sides. The bottoms of the gas spring 21 and the damper 22 are fixedly connected to the bed frame 3. A mattress 4 is provided on the top of the bed frame 3. The side of the bed frame 3 is provided with a mounting lock 31 that matches the inner top of the bed cabinet 1. The bottom of the bed frame 3 is provided with a handle 32.

[0032] Specifically, both sides of the bed frame 3 are movably connected to the inner side of the bed cabinet 1 via drive rivet 24. Mounting plate assemblies 23 are sleeved on the drive rivet 24, and the left and right mounting plate assemblies 23 are fixedly connected to the bed cabinet 1. The bed frame 3 is rotatably connected to the left and right mounting plate assemblies 23. When the bed frame 3 is flipped, the gas spring 21 and damper 22 provide assistance and cushioning.

[0033] When the bed frame 3 flips downward, the desk drive rod assembly 51 pulls the desk rotating plate assembly 53 upward through the drive rivet 24 on the mounting plate assembly 23 set on the left and right to ensure that the tabletop is level;

[0034] When the bed frame 3 flips upward, the desk drive rod assembly 51 pushes the desk rotating plate assembly 53 downward through the drive rivet 24 on the mounting plate assembly 23 set on the left and right to ensure that the tabletop is level;

[0035] When the bed frame 3 is tilted down to a horizontal position, the desk fixing component 52 is supported on the ground by the desk reinforcing frame 6, which serves to support the bed frame 3 and ensure the reliability of the bed frame 3 in bearing weight.

[0036] Specifically, a desk reinforcing frame 6 is fixedly connected to one side of the desk rotating assembly 53, and a tabletop 7 is fixedly connected to the top of the desk reinforcing frame 6. The desk reinforcing frame 6 is fixedly connected to the desk rotating assembly 53, which serves to fix the tabletop 7 and ensure that the desk tabletop does not deform.

[0037] Specifically, the bottom of the desk reinforcing frame 6 is fixedly connected with foot pads 61, and the inner side of the desk fixing component 521 is provided with a tabletop limiting pin 71. The foot pads 61 are made of rubber. When the bed frame 3 is unfolded, the bottom of the desk reinforcing frame 6 is supported by the rubber foot pads 61 to achieve a stable support effect. A tabletop limiting pin 71 is provided above the tabletop 7. Because the tabletop 7 can be angled under the action of the rotating component 55, the top of the tabletop 7 is subjected to force when in use, so that the tabletop limiting pin 71 can play a limiting role and ensure that the tabletop 7 always remains horizontal when in use.

[0038] Specifically, a decorative cover 25 is provided on the outer side of the top of the gas spring 21, damper 22 and mounting plate assembly 23. The decorative cover 25 is installed on the inner side of the bed cabinet 1 and serves a decorative and beautifying function.

[0039] When the user needs to use the desk, the mounting lock 31 is opened, and the lever 32 is pulled by operating the assist mechanism 2. The gas spring 21 assists in flipping the bed frame 3 upwards, and the mounting plate assembly 23 drives the bed frame 3 upwards. When the bed frame 3 flips upwards by ninety degrees, it is in its final position, maintaining the folded state of the bed frame 3 and mattress 4. The mounting lock 31 is then used to lock it in place. Figure 2 As shown, when the bed frame 3 is folded down, the tabletop 7 unfolds and can be used. Conversely, when the user needs to sleep, the gas spring 21 assists in lowering the bed frame 3, and the mounting plate assembly 23 lowers the bed frame 3. When the bed frame 3 is lowered to ninety degrees, the tabletop 7 extends out, positioned below the bed frame 3 and mattress 4, flush with the mattress 4. This ensures that the tabletop 7 does not protrude beyond the mattress 4 after unfolding, avoiding potential bumps during use. The damper 22 controls the lifting speed of the gas spring 21 for smoother operation. This application links the tabletop 7 with the bed frame 3, synchronizing the lifting and rotating operations of the tabletop 7 with the folding and extending of the bed frame 3, effectively achieving a flexible desk conversion function.

[0040] The gas spring 21 provides lifting assistance to the bed frame 3, and the mounting plate assembly 23 transmits the force of the gas spring 21 to the bed frame 3, realizing the folding and extension of the bed frame 3. The linkage mechanism 5 connects the desk to the bed frame 3, realizing the up-and-down lifting and rotation adjustment of the desk.

[0041] In summary, this linkage mechanism and the flip-up bed with a desk effectively combine the functions of the bed frame 3 and the desk into one, saving space and increasing space utilization. It also meets the multifunctional needs of modern families, is easy to use, and the bed frame 3 can be easily folded and unfolded. After the bed frame 3 is unfolded, the tabletop 7 is flush with the mattress 4, avoiding the problem of easy bumps during use. This allows the bed frame and the desk to be perfectly integrated, combining functionality and aesthetics.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
