Problems solved by technology

In the prior art, the back support unit is only a movable plate, which is turned up and down under the drive of the electric cylinder to adjust the angle of the back support unit, but some problems also arise: when the back is lifted, the electric cylinder of the movable support is used to drive The back support unit is turned upwards. If the distance against the wall is too small, the angle between the support link (supporting and rotating to connect the backboard) and the backboard is too small. When it needs to be leveled (under no load), the backboard cannot Relying on its own weight to turn downwards, it needs to rely on the drive of the motor to level the backplane, which has potential safety hazards (such as pinching hands); moreover, the movable support needs to move a large distance, which requires a relatively large installation space for the motor and the speed of the motor. high, high cost

Embodiment Construction

[0022] Attached below Figure 1-6 The present invention is further illustrated with specific examples.

[0023] like Figure 1-2 As shown, an automatically movable bed device includes:

[0024] bed frame 21;

[0025] A movable bracket 20 that can be movably arranged in the bed frame 21;

[0026] a bed board set arranged on the movable bracket 20, the bed board set includes a back support unit, a hip board 14, a leg board 15, and a foot board 16;

[0027] The leg electric cylinder 18 and the foot support rod 17, the two ends of the leg electric cylinder 18 are respectively connected to the lower side of the leg plate 14 and the movable bracket 20 by rotation, and the two ends of the foot support rod 17 are respectively connected to the foot plate 16 and the movable support. 20. The leg plate 15, the foot plate 16 and the foot support rod 17 form a quadrilateral link mechanism. Under the driving of the leg electric cylinder 18, the leg plate 15 is lifted up, and the foot pla...

Abstract

The invention discloses a bed device capable of automatically moving. The bed device comprises a bed frame; the movable bracket is arranged in the bed frame in a front-back movable manner; the bed board group is arranged on the movable bracket and comprises a back supporting unit; wherein the back supporting unit is divided into a back plate and a waist plate, the back plate can rotate relative to the waist plate, the waist plate can rotate relative to the hip plate, a driving part composed of a driving electric cylinder and a linkage connecting rod set is arranged below the back supporting unit, and the driving electric cylinder, the linkage connecting rod set and the back supporting unit are in transmission fit in sequence in the using process. Elevation angles of the back plate and the waist plate are adjusted; the included angle between the movable supporting rod and the waist plate is suitable for the condition that the back supporting unit falls by means of self weight.

Description

technical field [0001] The invention relates to the technical field of electric beds, in particular to an electric bed that can adjust the front and rear movements during the back-lifting process. Background technique [0002] At present, there is an electric bed that can be adjusted fore and aft during the back lifting process, which includes a movable bracket that can be movably arranged in the bed frame forward and backward, and a bed board set on the movable bracket. The bed board set includes a back support unit. In the prior art, the back support unit is only a movable plate, which is turned up and down under the drive of the electric cylinder to adjust the angle of the back support unit, but there are also some problems: when the back is lifted, the electric cylinder of the movable bracket is used to drive the back support unit. The back support unit is turned upward. If the distance against the wall is too small, the angle between the support link (supporting and rot...
