Technical Field

[0001] This utility model belongs to the field of electric bed technology, and in particular relates to an energy-saving drive device for electric beds. Background Technology

[0002] An electric bed is a piece of furniture that uses an electric drive system to adjust the height and angle of the bed frame. It is usually used to provide a more comfortable sleeping experience or to meet specific medical needs. During use, the electric bed is mainly driven by a drive device.

[0003] Traditional electric bed drives typically employ a multi-drive system using a large electric motor connected to a motor rod. The bed frame is moved via a hinged connection, or the movement is achieved directly using a hinged rod or belt. While this method provides strong power and precise control, it also has drawbacks, particularly in adjusting the bed frame position. These drawbacks include high power consumption, especially when significant adjustments to the bed frame angle are required. Therefore, reducing the overall power consumption of the motor is crucial to improving the overall performance.

[0004] Therefore, we propose an energy-saving drive device for electric beds to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the motor consumes a lot of energy during the driving process of an electric bed in the prior art, and to propose an energy-saving drive device for an electric bed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An energy-saving drive device for an electric bed includes two intermediate plates, the outer surfaces of which are hinged to each other. Each intermediate plate has a leg plate and a head plate hinged to its outer surface. A first electric push rod is located below each leg plate and the head plate. A first rotating frame is located on the outer side of the telescopic end of each first electric push rod. Bolts are hinged to the inner wall of the first rotating frame and the outer surface of the telescopic end of the first electric push rod. A rotating rod is fixedly connected to the outer surface of each set of first rotating frames. A support frame is fixedly connected to the outer surface of each rotating rod. Two roller frames are fixedly connected to the outer surface of each support frame. The inner wall of the roller frame is rotatably connected to roller bodies. Two second electric push rods are arranged below the middle plate. The outer surface of the telescopic end of each second electric push rod is movably hinged to a second rotating frame. A partition plate is arranged above each second rotating frame. The upper surface of each partition plate is fixedly connected to the bottom surface of the middle plate. An inclined frame and a trapezoidal frame are fixedly connected to the outer surface of each partition plate. A support plate is fixedly connected to the upper surface of each trapezoidal frame. The upper surface of each support plate is in contact with the bottom surface of the middle plate. The upper surface of each partition plate is fixedly connected to the bottom surface of the middle plate. A controller body is fixedly connected to the upper surface of one of the middle plates.

[0007] Preferably, the outer surfaces of the two head plates are hinged to each other, the outer surfaces of the two leg plates are hinged to each other, and a fixing frame is fixedly connected to the outer surface of the controller body, with the bottom surface of the fixing frame fixedly connected to the upper surface of one of the intermediate plates.

[0008] Preferably, a protective pad is fixedly connected to the bottom surface of each head plate and the bottom surface of each leg plate, and the bottom surface of each protective pad is in contact with the outer surface of the roller body.

[0009] Preferably, a U-shaped frame is fixedly connected to the outer surface of each second electric push rod and the outer surface of each first electric push rod, and the outer surface of each U-shaped frame is fixedly connected to the outer surface of the electric bed frame.

[0010] Preferably, each of the rotating rods has two fixed frames rotatably connected to its opposite ends, and the outer surface of each fixed frame is fixedly connected to the outer surface of the electric bed frame.

[0011] Preferably, each bolt has a nut threaded onto its outer surface, and the controller body is electrically connected to the first electric push rod and the second electric push rod respectively via wires.

Under the support of the bed frame and other fixed entities, the first electric push rod drives the first rotating frame and the rotating rod to rotate around the axis of the rotating rod, which in turn drives the support frame to rotate. The rotation of the support frame causes the roller frame and roller body to contact the bottom surface of the protective pad. Then, by utilizing the movable hinge relationship between the leg plate and the head plate and the middle plate respectively, the bottom surface of the head plate and the leg plate can be raised and lowered. The controller controls the extension and retraction of the second electric push rod. Under the support of the trapezoidal frame and the second rotating frame, the extension and retraction of the second electric push rod drives the partition plate and the support plate to move up and down. By utilizing the movable hinge relationship between the two intermediate plates, the two intermediate plates can be flipped to the side. This device achieves energy saving and improves energy utilization. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5An energy-saving drive device for an electric bed includes two intermediate plates 1, the outer surfaces of which are hinged to each other. Each intermediate plate 1 has a leg plate 2 and a head plate 3 hinged to its outer surface. The outer surfaces of the two head plates 3 and the two leg plates 2 are hinged to each other. A first electric push rod 9 is provided below each leg plate 2 and below each head plate 3. A first rotating frame 11 is provided on the outer side of the telescopic end of each first electric push rod 9. The inner wall of the first rotating frame 11 and the outer surface of the telescopic end of the first electric push rod 9 are hinged together with bolts 13. A nut 12 is threaded onto the outer surface of each bolt 13 to increase the stability of the bolt 13.

[0017] Each set of first rotating frames 11 has a rotating rod 7 fixedly connected to its outer surface. Each rotating rod 7 has a support frame 8 fixedly connected to its outer surface. Each support frame 8 has two roller frames 20 fixedly connected to its outer surface. Each roller frame 20 has a roller body 22 rotatably connected to its inner wall. Each head plate 3 and leg plate 2 has a protective pad 21 fixedly connected to its bottom surface. The bottom surface of each protective pad 21 is in contact with the outer surface of the roller body 22. The protective pad 21 can protect the roller body 22 and prevent wear during use.

[0018] Two second electric push rods 18 are provided below the middle plate 1. The outer surface of the telescopic end of each second electric push rod 18 is movably hinged with a second rotating frame 17. The outer surface of each bolt 13 is threaded with a nut 12, which can fix the bolt 13 and prevent the device from falling off during use.

[0019] Each second electric push rod 18 and each first electric push rod 9 are fixedly connected to a U-shaped frame 10 on their outer surfaces. The outer surface of each U-shaped frame 10 is fixedly connected to the outer surface of the electric bed frame. The U-shaped frame 10 can fix the second electric push rod 18 and the first electric push rod 9, preventing the first electric push rod 9 and the second electric push rod 18 from shaking during use.

[0020] Each second rotating frame 17 is equipped with a partition plate 19 above it. The upper surface of each partition plate 19 is fixedly connected to the bottom surface of the intermediate plate 1. An inclined frame 16 and a trapezoidal frame 15 are fixedly connected to the outer surface of each partition plate 19. A support plate 14 is fixedly connected to the upper surface of each trapezoidal frame 15. The upper surface of each support plate 14 is in contact with the bottom surface of the intermediate plate 1. The upper surface of each partition plate 19 is fixedly connected to the bottom surface of the intermediate plate 1. A controller body 5 is fixedly connected to the upper surface of one of the intermediate plates 1. A fixing frame 4 is fixedly connected to the outer surface of the controller body 5. The bottom surface of the fixing frame 4 is fixedly connected to the upper surface of one of the intermediate plates 1. The controller body 5 is electrically connected to the first electric push rod 9 and the second electric push rod 18 via wires. The fixing frame 4 protects the controller body 5 and prevents it from moving during use. The controller consists of two parts: hardware and software. The system should include a central processing unit (CPU) for computation, input / output (I / O) interfaces for connecting sensors and actuators, memory for storing programs and data, and power supply and communication modules. The software encompasses control algorithms, a real-time operating system (RTOS), and a human-machine interface, all working together to ensure precise and efficient system control. This technology is widely used in industrial automation, smart homes, and automotive electronics. A controller is a core device that regulates system operation by processing input signals in real time and generating control commands. Its working principle can be summarized as follows: First, it collects signals from sensors or external inputs such as temperature and speed, compares them with preset target values ​​to calculate the deviation; then, it uses built-in algorithms such as PID control and logical judgment to analyze the deviation and generate adjustment commands; finally, it drives actuators such as motors and valves through output interfaces to adjust the system state, while continuously monitoring the effect through closed-loop feedback to achieve dynamic stability. The controller enables control of the electrical components in this technical solution.

[0021] The working principle of this utility model is as follows: In use, first connect the controller body 5, the first electric push rod 9, and the second electric push rod 18 to the power supply. When adjusting the electric bed using this device, the controller body 5 controls the first electric push rod 9 to extend and retract. Under the support of the bed frame and other fixed entities, the first electric push rod 9 drives the first rotating frame 11 and the rotating rod 7 to rotate around the axis of the rotating rod 7, causing the support frame 8 to rotate. The rotation of the support frame 8 causes the roller frame 20 and the roller body 22 to contact the bottom surface of the protective pad 21. Then, the leg plate 2 and the head plate 3 respectively contact the middle plate... The device features a movable hinge connection, allowing for the raising and lowering of the headboard 3 and legboard 2. This enables adjustment of the user's head and legs. The controller body 5 controls the extension and retraction of the second electric push rod 18. Supported by the trapezoidal frame 15 and the second rotating frame 17, the second electric push rod 18 drives the partition plate 19 and the support plate 14 to move up and down. The movable hinge connection between the two intermediate plates 1 allows for the side-flipping of the two intermediate plates 1. This device, through the operation of the second electric push rod 18 and the first electric push rod 9, enables the operation of the electric bed, saving electricity and improving the device's working efficiency.
