Description
Technical Field
[0001] This utility model relates to the field of bed board lifting technology, and in particular to a bed board lifting device for modular apartment beds. Background Technology
[0002] With the acceleration of urbanization and increasingly compact living spaces, modular apartment beds are widely used in apartments, dormitories, and small residences due to their efficient use of vertical space. These beds typically combine sleeping and storage areas, with the bed-lifting mechanism being the core component for realizing this storage function. Its performance directly impacts the user experience and space utilization efficiency of the modular apartment bed. The bed-lifting mechanism is designed to allow users to easily access the under-bed storage space to store suitcases, seasonal clothing, bedding, and other items, thereby expanding practical functions within a limited living space.
[0003] In existing technology, the bed board lifting mechanism of modular apartment beds is mainly manually operated, with two common structures: the pull rod type and the hinge-assisted type. The pull rod type manual lifting mechanism usually has a long strip of metal fixed to the edge of the bed board, with a non-slip handle at the end of the pull rod. The bed board is connected to the bed frame by a hinge. The user needs to grip the handle and pull upwards, relying on arm strength to overcome the weight of the bed board and mattress to lift it. Its technical principle is to apply direct pulling force by human force, and use the rotation characteristics of the hinge to change the angle of the bed board. After lifting to the appropriate position, the user needs to manually fasten the buckles on both sides of the bed frame to fix the bed board.
[0004] However, existing manual bed board lifting devices have significant drawbacks during the bed board's descent. Lacking an effective cushioning mechanism, the bed board, along with the mattress, slams rapidly against the bed frame upon closing. This rapid impact generates considerable force, and repeated impacts over time can cause the connection between the bed board and the bed frame to gradually loosen, such as loosening of hinge screws and wear on connecting shafts. Simultaneously, this impact can damage the wooden or metal frame of the bed frame, easily leading to frame deformation or even cracking. This severely affects the structural stability and safety of the modular apartment bed, significantly shortening its lifespan and increasing the frequency and cost of maintenance and replacement. Therefore, a bed board lifting device for modular apartment beds is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a bed board lifting device for a modular apartment bed, which aims to improve the problem in the prior art where the bed board will quickly fall onto the bed frame due to gravity when it falls back.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A bed board lifting device for a modular apartment bed includes a bed frame, a support frame fixedly connected to the bottom of the bed frame, a lifting component inside the bed frame, a bed board rotatably connected to the top of the bed frame, and a buffer component at the bottom of the bed board;
[0008] The cushioning assembly includes a cushioning pad, the top of which is fixedly connected to the bottom of the bed board. A fixed column is fixedly connected to the inner wall of the bed. A sliding column is slidably connected to the inner wall of the fixed column. A fixed block is fixedly connected to the bottom of the sliding column. A spring is sleeved on the outer wall of the sliding column. One end of the spring is fixedly connected to the inner wall of the fixed column, and the other end of the spring is fixedly connected to the top of the fixed block. A spring is provided at the bottom of the fixed block. One end of the spring is fixedly connected to the bottom of the fixed block, and the other end of the spring is fixedly connected to the inner wall of the fixed column.
[0009] As a further description of the above technical solution:
[0010] The lifting assembly includes a slider, the outer wall of which is disposed inside the bed body, and a partition is fixedly connected to the inner wall of the bed body;
[0011] As a further description of the above technical solution:
[0012] A guide rod is fixedly connected to the inner wall of the bed, and the inner wall of the slider is slidably connected to the outer wall of the guide rod.
[0013] As a further description of the above technical solution:
[0014] A limiting plate is fixedly connected to the outer wall of the guide rod, and the outer wall of the limiting plate and the outer wall of the slider are in contact.
[0015] As a further description of the above technical solution:
[0016] An electric push rod is fixedly connected to the inner wall of the bed body, and the output end of the electric push rod is fixedly connected to the outer wall of the slider.
[0017] As a further description of the above technical solution:
[0018] A fixing rod is fixedly connected to the outer wall of the slider, and the fixing rod is rotatably connected to the outer wall of the connecting arm.
[0019] As a further description of the above technical solution:
[0020] The outer wall of the connecting arm is rotatably connected to a second fixing rod, one end of which is fixedly connected to a connecting block, and the top of the connecting block is fixedly connected to the bottom of the bed board.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the buffer pad contacts the sliding column, and then the sliding column slides on the inner wall of the fixed column, achieving a buffering effect when the bed board is closed. This prevents the bed board from falling rapidly onto the bed frame due to gravity when it falls back, which could lead to loosening of the connection between the bed board and the bed frame after long-term use, or even deformation or cracking of the wood or metal frame, shortening the service life of the modular apartment bed. This reduces the impact on the bed structure and lifting device components when the bed board is raised and lowered, reduces wear and tear, reduces the probability of failure, and thus extends the overall service life of the modular apartment bed.
[0023] 2. In this utility model, the slider is moved by an electric push rod, and then the slider slides on the outer wall of the guide column to achieve the effect of opening and closing the bed board. This avoids the need to manually lift the bed board, which is very difficult to do if there is a heavy mattress, especially for users with less strength. Moreover, when operating manually, the bed board is prone to shaking due to uneven force, which may cause items to fall or even injure the user. This invention can lift the bed board accurately and stably. Attached Figure Description

[0031] 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.
[0032] Reference Figures 1-3 This utility model provides an embodiment of a modular apartment bed with a bed board lifting device, including a bed body 1. A support frame 2 is fixedly connected to the bottom of the bed body 1. The support frame 2 is used to raise the bed body 1 to a certain height off the ground to prevent the bed body 1 from directly contacting the ground and being damaged by moisture. A lifting component is provided inside the bed body 1. A bed board 3 is rotatably connected to the top of the bed body 1. A buffer component is provided at the bottom of the bed board 3. The buffer component includes a buffer pad 4. When the bed board 3 is about to close, the buffer pad 4 will first contact the top of the sliding column 6 and absorb part of the impact force through its own elastic deformation to prevent the bed board 3 from directly colliding with the bed body 1. The top of the buffer pad 4 is fixedly connected to the bottom of the bed board 3. A fixing column 5 is fixedly connected to the inner wall of the bed body 1. A sliding column 6 is slidably connected to the inner wall of the fixing column 5. A fixing block 7 is fixedly connected to the bottom of the sliding column 6. Block 7 connects the sliding column 6 to spring 8 and spring 9, transmitting the pressure on the sliding column 6 to the springs while limiting the positions of spring 8 and spring 9 to prevent them from shifting during extension and retraction. Spring 8 is sleeved on the outer wall of the sliding column 6, with one end of spring 8 fixedly connected to the inner wall of the fixed column 5 and the other end fixedly connected to the top of the fixed block 7. When the sliding column 6 moves downward, spring 8 is stretched, generating a downward pulling force, which acts as a first-level buffer. Spring 9 is provided at the bottom of the fixed block 7, with one end fixedly connected to the bottom of the fixed block 7 and the other end fixedly connected to the inner wall of the fixed column 5. When spring 8 is stretched, the fixed block 7 compresses spring 9. Through the combined action of the two springs, the buffering effect is further enhanced, preventing excessive impact force when the bed board 3 falls.
[0033] Reference Figure 1 , Figure 4 and Figure 5The lifting assembly includes a slider 13, the outer wall of which is located inside the bed frame 1. A partition 18 is fixedly connected to the inner wall of the bed frame 1, separating the internal space of the bed frame 1 and isolating the lifting assembly from other areas. A guide rod 10 is fixedly connected to the inner wall of the bed frame 1, guiding the slider 13 to move linearly along the axis of the guide rod 10, preventing the slider 13 from deviating or jamming during movement. The inner wall of the slider 13 is slidably connected to the outer wall of the guide rod 10, and the slider 13 moves linearly reciprocatingly in coordination with the guide rod 10. The movement of the slider 13 drives the connecting arm 15 to rotate, thereby driving the bed board 3 to rise and fall. A limit plate 11 is fixedly connected to the outer wall of the guide rod 10, with the outer wall of the limit plate 11 fitting against the outer wall of the slider 13. The limit plate 11 limits the sliding range of the slider 13, preventing excessive movement of the slider 13 and ensuring the lifting assembly is completed. For safe operation of the components, an electric push rod 12 is fixedly connected to the inner wall of the bed 1. The output end of the electric push rod 12 is fixedly connected to the outer wall of the slider 13. A fixing rod 14 is fixedly connected to the outer wall of the slider 13. A connecting arm 15 is rotatably connected to the outer wall of the fixing rod 14. A fixing rod 16 is rotatably connected to the outer wall of the connecting arm 15. A connecting block 17 is fixedly connected to one end of the fixing rod 16. The top of the connecting block 17 is fixedly connected to the bottom of the bed board 3. When the electric push rod 12 pushes the slider 13 to slide outward along the guide rod 10, the slider 13 will drive the connecting arm 15 to rotate outward through the fixing rod 14. The connecting arm 15 will then push the bed board 3 upward through the fixing rod 16 and the connecting block 17. When the electric push rod 12 pulls the slider 13 to slide inward, the connecting arm 15 will rotate inward, causing the bed board 3 to descend downward, realizing the automatic lifting and closing of the bed board 3, and achieving the effect of conveniently controlling the opening and closing of the space under the bed.
[0034] Working principle: When the bed board 3 is closed, the bed board 3 drives the buffer pad 4 to move. When the buffer pad 4 comes into contact with the sliding column 6, it drives the sliding column 6 to slide on the inner wall of the fixed column 5. Then, the sliding of the sliding column 6 drives the fixed block 7 to move. Then, the movement of the fixed block 7 compresses and stretches the spring 8 and the spring 9, preventing the bed board from falling quickly onto the bed frame 1 due to gravity when it falls back. Long-term use will cause the connection between the bed board 3 and the bed frame 1 to loosen, and may even cause deformation or cracking of the wood and metal frame, shortening the service life of the modular apartment bed.
[0035] When lifting the bed board 3, the electric push rod 12 is activated first. The electric push rod 12 pushes the slider 13 to slide on the outer wall of the guide rod 10. The sliding of the slider 13 then moves the fixed rod 14. The movement of the fixed rod 14 then causes the connecting arm 15 to rotate on the outer wall of the fixed rod 14. The rotation of the connecting arm 15 then moves the connecting block 17. The movement of the connecting block 17 then causes the bed board 3 to rotate on the outer wall of the bed frame 1. The partition 18 then separates the lifting assembly from the storage space to avoid manually lifting the bed board 3. If there is a heavy mattress, the opening process is very difficult, especially for users with less strength. It is often difficult to complete smoothly. Moreover, when operating manually, the bed board is prone to shaking due to uneven force, causing items to fall or even injuring the user.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
