The structure of this embodiment is a double bed frame structure, and each single person can adjust the posture of the upper body and the lower body separately. Please refer to Figures 18 to 21 , the figure shows the structure of the electric bed frame in different states.

[0069] In other embodiments, the electric bed frame includes two movable frames 2 and two electric adjustment mechanisms 3, and the bed frame 1 includes three side bars 11, three first bed legs 110, two first bottom bars 120, six second bed legs 130 and four second bottom bars 140. The bed frame structure is also a double bed, but each single position can only adjust the upper body posture, or each single position can only adjust the lower body posture, or only one of the single positions can adjust the upper and lower body postures.

[0070] Therefore, there are many embodiments of the structure of the electric bed frame, which will not be described in detail here; those skilled in the art can know the specific structures of various embodiments based on the contents of the specification.

[0071] In addition, in different embodiments, the outer sides of the side rod 11, the first bed leg 110 and the second bed leg 130 on the outside of the bed frame 1 can be set to an arc structure, which can not only reduce the damage to the user when colliding with the side rod, the first bed leg 110 and the second bed leg 130, but also improve the aesthetics.

[0072] See also Fig.16 The electric adjustment mechanism 3 includes a driving motor 31, a screw rod 32 and a movable housing 33. The output end of the driving motor 31 is connected to one end of the screw rod 32 and is used to drive the screw rod 32 to rotate. The movable housing 31 is sleeved on the screw rod 32 and is threadedly connected to the screw rod 32. The driving motor 31 is specifically installed on the second bottom rod 140, and one end of the movable housing 33 away from the driving motor 31 is connected to the movable frame 2. The driving motor 31 rotates, which can drive the screw rod 32 to rotate around its axis. When the screw rod 32 rotates, the movable housing 33 can be driven to move relative to the screw rod 32 in the vertical direction of the screw rod 32. The driving motor 31 can realize forward and reverse rotation through control, so the screw rod 32 can also rotate forward or reverse. The movable housing 33 can move in two directions under the rotation of the screw rod 32, thereby realizing the adjustment of the inclination angle of the movable frame 2.

[0073] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
