[0002] People's living spaces are facing unprecedented challenges of compactness. Against this backdrop, consumers have put forward almost stringent requirements for the space utilization efficiency of furniture, expecting that every inch of home space can achieve efficient and flexible functional transformation.

[0003] Most existing bed frames adopt a fixed structure design, which occupies a constant space area whether in daily use or when not in use. When residents need to temporarily expand their activity area, re-plan the spatial layout, or try to achieve "one room for multiple uses" in small apartments, these fixed bed frames are like stubborn spatial barriers, which seriously hinder the flexible allocation and efficient use of space and make it difficult to meet the contemporary people's pursuit of spatial versatility and practicality.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See attached document Figure 1 - Appendix Figure 4 This utility model provides a bed frame structure with automatic extension and retraction function, including a bed frame assembly 1, a bed board assembly 2 connected inside the bed frame assembly 1, the bed frame assembly 1 including a fixed headboard 11, a middle support plate 12, and a movable bed tail plate 13, two limiting tubes 14 are fixedly inserted between the fixed headboard 11 and the middle support plate 12, two limiting rods 15 are fixedly provided on one side of the movable bed tail plate 13, a threaded rod 16 is inserted between the fixed headboard 11 and the middle support plate 12, a threaded seat 17 is sleeved on the outside of the threaded rod 16, and two connecting rods 18 are provided on one side of the threaded seat 17. The bed board assembly 2 includes multiple fixed bed boards 21 and multiple movable beds 23, one end of the multiple fixed bed boards 21 is fixedly connected to the fixed headboard 11, the other end of the multiple fixed bed boards 21 is fixedly provided on the top of the middle support plate 12, limiting grooves 22 are opened on both sides of the multiple fixed bed boards 21, one end of the multiple movable beds 23 is fixedly connected to the movable bed tail plate 13, and limiting posts 24 are fixedly provided on both sides of the multiple movable beds 23;

[0024] In this embodiment, in order to achieve the automatic extension and retraction function of the bed frame, the drive motor 3, as the core power source, is fixed to one side of the fixed headboard 11. Its output end is connected to the threaded rod 16. When the motor starts, the threaded rod 16 rotates accordingly. Based on the thread transmission principle, the threaded seat 17, which is sleeved on the outside of the threaded rod 16, moves linearly along the axial direction of the threaded rod 16. The threaded seat 17 is connected to the movable tailboard 13 through the connecting rod 18. When the threaded seat 17 moves on the threaded rod 16, it drives the connecting rod 18 to move, thereby driving the movable tailboard 13 to move. At the same time, the limiting posts 24 on both sides of the movable bed board 23 slide in cooperation with the limiting grooves 22 on both sides of the fixed bed board 21. During the movement of the movable tailboard 13, the limiting posts 24 slide along the limiting grooves 22, so that the movable bed board 23 and the fixed bed board 21 always maintain a stable connection. The movable bed board 23 can smoothly unfold or retract with the movement of the movable tailboard 13, realizing the automatic extension and retraction function of the entire bed frame.

[0025] To achieve the automatic extension and retraction of the bed frame, the device employs the following technical solution: A drive motor 3 is fixedly mounted on one side of the fixed headboard 11. The output end of the drive motor 3 is fixedly connected to one end of a threaded rod 16. One end of a limiting rod 15 extends into the limiting tube 14 and is slidably connected to the limiting tube 14. Both ends of the threaded rod 16 pass through the fixed headboard 11 and the intermediate support plate 12, respectively, and are connected to the fixed headboard 11 and the intermediate support plate 12 via bearings. A threaded seat 17 is fitted onto the outside of the threaded rod 16 and is threadedly connected to the threaded rod 16. One end of a connecting rod 18 is fixedly connected to the threaded seat 17, and the other end of the connecting rod 18 is fixedly connected to the movable tailboard 13. The connecting rod 18 passes through the intermediate support plate 12 and is slidably connected to the intermediate support plate 12.

[0026] When the drive motor 3 starts, it can drive the threaded rod 16 to rotate. When the threaded rod 16 rotates, the threaded seat 17 can make linear motion on the threaded rod 16. The linear motion of the threaded seat 17 can drive the movable tail plate 13 to move through the connecting rod 18. One end of the limiting rod 15 extends into the limiting tube 14, which can limit the movement direction of the movable tail plate 13 and ensure its smooth sliding.

[0027] In order to achieve the purpose of smooth extension and retraction of the bed board, the device adopts the following technical solution: the limiting post 24 extends into the limiting groove 22 and slides in connection with the limiting groove 22. During the movement of the movable bed tail board 13, the limiting post 24 on the movable bed board 23 slides along the limiting groove 22 of the fixed bed board 21 to ensure that the movable bed board 23 and the fixed bed board 21 always maintain a stable connection, and the movable bed board 23 can be smoothly extended or retracted.

[0028] The usage process of this utility model is as follows: To prevent friction during the movement of the movable bed tailboard 13, wheels can be installed at the bottom of the movable bed tailboard 13. When the bed frame needs to be retracted, the drive motor 3 on one side of the fixed headboard 11 is activated. The drive motor 3 drives the threaded rod 16 to rotate clockwise. The threaded seat 17, threaded to the threaded rod 16, moves along the threaded rod 16 towards the fixed headboard 11. The threaded seat 17 pulls the movable bed tailboard 13 through the connecting rod 18, causing the movable bed tailboard 13 to move away from the fixed headboard 11 along the guide structure composed of the limiting tube 14 and the limiting rod 15. As the movable bed board 23 slides, the limiting post 24 on the movable bed board 23 slides along the limiting groove 22 of the fixed bed board 21. As the movable bed tail board 13 moves, the movable bed board 23 gradually retracts into the fixed bed board 21 until the required bed frame length is reached. At this time, the drive motor 3 is turned off. When the bed frame needs to be extended, the drive motor 3 is started to rotate counterclockwise, and the threaded seat 17 moves away from the fixed headboard 11. The connecting rod 18 pushes the movable bed tail board 13 to slide away from the fixed headboard 11, and the movable bed board 23 gradually extends until the bed frame is extended to the required size. Then the drive motor 3 is turned off.

[0029] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
