Description

Technical Field

[0001] The utility model relates to the field of intelligent beds, in particular to an intelligent lifting bed. Background Art

[0002] A smart bed usually includes a fixed plate and a liftable plate rotatably connected to the fixed plate. The liftable plate adjusts the lifting angle through a lifting device so that the user can be in a comfortable posture. However, the smart bed cannot determine the current angle position of the liftable plate. In the event of a sudden power outage or shutdown, the liftable plate needs to return to its initial position, and the lifting device then drives the liftable plate to the preset position again according to the position signal, which will increase the power consumption of the smart bed.

[0003] In the prior art, a multi-angle lifting bed is disclosed, which includes an adjustable bed board and a bed frame. The adjustable bed board and the bed frame are connected to a rotating support seat via a rotating shaft. An encoder is installed on the shaft end of the rotating shaft. By installing the encoder on the rotating shaft of the adjustable bed board, the rotation angle of the rotating shaft can be accurately detected, and then the inclination angle of the adjustable bed board can be accurately adjusted. However, since the adjustable bed board is prone to shaking (left and right swing, up and down swing, etc.) during use, inaccurate angle measurement will result in inaccurate angle measurement, and the structure of directly connecting the adjustable bed board via the rotating shaft is easily damaged after repeated shaking, and has a short service life.

[0004] Also, the bed frame in the prior art is usually made of iron. In order to make the bed frame more beautiful when viewed from the side, a wooden decorative panel is installed on the side of the bed frame by screwing. This screw-locking installation method is inefficient and labor-intensive. There is also a method of decorating the side of the bed frame by brushing wood grain, which is cumbersome.

[0005] In addition, for a double smart bed, it will be provided with two adjustable bed boards arranged side by side with a spacing, and the adjustment angles of the two adjustable bed boards can be controlled separately. As a result, when the difference in the rotation angles of the two adjustable bed boards is large, the two adjustable bed boards will be misaligned up and down, thereby creating a gap. The user's hands or feet can easily get stuck in the gap and be pinched, resulting in poor safety.

[0006] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content
