[0003] In the field of lifting cloud bed technology, the power transmission efficiency of traditional lifting drive devices needs improvement, and their energy consumption is relatively high. Some devices lack an effective balancing mechanism, causing the motor to bear a large load when driving the bed to rise and fall. This not only increases energy consumption but also makes the motor prone to failure due to long-term high-load operation, increasing maintenance costs. Therefore, there is an urgent need for a lifting drive device for lifting cloud beds to solve the above problems. Utility Model Content

[0031] Reference Figures 1-4 A lifting drive device for a lifting cloud bed includes a column 3 disposed on one side of the bed body 1 and the bed frame 2. A crossbar 10 is fixedly connected to the outer wall of one side of the column 3. Two columns 3 are fixedly connected to each other through the crossbar 10. A power component is disposed on one side of the crossbar 10. A support column 4 is fixedly connected to the middle of the crossbar 10.

[0032] A transmission assembly for lifting the bed body 1 and bed frame 2 is provided below the crossbar 10. The fixed connection between the column 3 and the crossbar 10 forms a stable support frame. The support column 4 further enhances the load-bearing capacity of the crossbar 10, providing a solid installation foundation for the power assembly and transmission assembly, and ensuring the reliability of the overall structure of the device. The power assembly provides driving force for the lifting of the bed body 1 and bed frame 2, while the transmission assembly is responsible for transmitting power to the bed frame 2 to realize the lifting action of the bed body 1.

[0033] Furthermore, the power assembly includes a mounting bracket 8 fixedly connected to the outer wall of one side of the crossbar 10. A motor 7 is fixedly connected to one side of the mounting bracket 8. The mounting bracket 8 provides a firm mounting position for the motor 7, ensuring that the motor 7 remains stable during operation and avoiding positional displacement due to vibration, which would affect the stability of the power output and ensure the normal operation of the power assembly.

[0034] Furthermore, the output end of the motor 7 is fixedly connected to a first gear disk 9, and a first chain 13 is meshed on the outer circumference of the first gear disk 9. The first chain 13 is also meshed with a second gear disk 12, and a rotating shaft 11 is fixedly connected to the inner circumference of the second gear disk 12. When the motor 7 is working, the output end drives the first gear disk 9 to rotate. The first gear disk 9 transmits power to the second gear disk 12 through the first chain 13, which in turn drives the rotating shaft 11 to rotate, thus realizing the effective transmission of power and providing a power foundation for the operation of subsequent transmission components.

[0035] Furthermore, a third gear disk 14 is fixedly connected to the outer circumference of the rotating shaft 11. There are two third gear disks 14, which are located at both ends of the rotating shaft 11. When the rotating shaft 11 rotates, the third gear disks 14 at both ends rotate synchronously. The design of the double third gear disks 14 can make the power transmission more balanced, provide symmetrical driving force for the transmission components, and help ensure the stability of the bed 1 when it is raised and lowered.

[0036] Furthermore, the transmission assembly includes a second chain 15 meshing with the outer circumference of the third gear disk 14. Both ends of the second chain 15 are fixedly connected to mounting plates 16. One side of one mounting plate 16 is fixedly connected to the bed frame 2. When the third gear disk 14 rotates, it drives the second chain 15 to move. The second chain 15 is connected to the bed frame 2 and the counterweight structure through the mounting plates 16 at both ends. When the second chain 15 is running, it can effectively pull the bed frame 2 up and down, thereby realizing the lifting function of the bed body 1 and completing the transmission of power from the transmission assembly to the bed body 1.

[0037] Furthermore, a sprocket mounting base 17 is fixedly connected to one side of the column 3. The third gear disk 14 is disposed inside the sprocket mounting base 17. The rotating shaft 11 is rotatably connected to the sprocket mounting base 17. The sprocket mounting base 17 provides a stable installation and support environment for the third gear disk 14 and the rotating shaft 11, restricting their radial and axial displacement, ensuring that the meshing of the third gear disk 14 with the second chain 15 is precise and stable, reducing shaking and friction during transmission, and ensuring the smoothness and reliability of transmission.

[0038] Furthermore, a fixing rod 6 is fixedly connected to one side of another mounting plate 16, and counterweights 5 are fixedly connected to both outer walls of the fixing rod 6. The fixing rod 6 connects the counterweights 5 to the mounting plate 16 at the end of the second chain 15. The counterweights 5 can balance the weight of the bed body 1 and the bed frame 2, reduce the load when the motor 7 drives the bed body 1 to lift and lower, thereby reducing energy consumption and extending the service life of the motor 7.

[0039] Working principle: Since the motor 7 is fixed to one side of the crossbar 10 through the mounting bracket 8, the first gear disk 9 is driven to rotate through the output end of the motor 7 during operation. The first gear disk 9 drives the second gear disk 12 and the rotating shaft 11 fixed thereto to rotate through the first chain 13. The third gear disk 14 at both ends of the rotating shaft 11 rotates together, thereby driving the meshing second chain 15 to move.

[0040] Since the two ends of the second chain 15 are connected to the bed frame 2 and the fixed rod 6 with counterweight 5 respectively through the mounting plate 16, when the second chain 15 is running, it will pull the bed frame 2 and the bed body 1 to achieve lifting and lowering. The sprocket mounting seat 17 on one side of the column 3 provides stable support for the rotating shaft 11 and the third gear disk 14, ensuring the smoothness of the transmission process. In this process, the symmetrical design of the double third gear disk 14 and the double second chain 15 can make the bed body 1 bear the force evenly, avoid tilting during lifting and lowering, and improve the safety of the device. At the same time, the setting of the counterweight 5 can balance the weight of the bed body 1, reduce the load on the motor 7, reduce energy consumption, and extend the service life of the motor 7. The fixed connection between the column 3 and the crossbar 10 and the reinforcement of the support column 4 enhance the stability of the overall structure, ensuring that the device maintains good load-bearing capacity and operational reliability during long-term use.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
