Example (b):

referring to fig. 1-4, the present embodiment provides a bed capable of being comfortably extended, which includes a bed frame 1, a back plate 2, a sliding plate 3, a bed tail plate 4 and a driving assembly. The bed frame 1 comprises a bed head and a bed tail. The sliding plate 3 and the back plate 2 are both disposed above the frame 1. Wherein, the sliding plate 3 is arranged at the bed tail, and the back plate 2 is arranged at the bed head. The sliding plate 3 includes a bed plate 32 and a bottom plate 31 disposed below the bed plate 32. The bed plate 32 and the bottom plate 31 are parallel to each other so that a receiving gap 33 is formed between the bed plate 32 and the bottom plate 31. The base plate 31 is provided with a plurality of rollers 311 to allow the sliding plate 3 to slide along the frame 1. In practice, the bottom plate 31 is provided with 4 rollers 311 and the 4 rollers 311 are distributed at four corners of the bottom plate 31. The base plate 31 is supported above the frame 1 by 4 rollers 311 so that the sliding plate 3 can be easily moved above the base plate 31. To reduce noise and reduce friction, 4 rollers 311 are each wrapped with a rubber sleeve.

The footboard 4 has one end connected to the foot of the frame 1 and the other end extending to the storage space 33 and supported by the bottom plate 31. In practice, the bed end plate 4 is provided with several rolling wheels 41. A plurality of rolling wheels 41 are closely attached to the upper surface of the bottom plate 31. This results in rolling friction between the footboard 4 and the bottom plate 31. The rolling wheel 41 is also wrapped with a rubber sleeve.

The drive assembly includes a drive motor 51 and a lead screw pair. The screw pair includes a screw 52 and a nut 53. The driving motor 51 is disposed on the bed frame 1 and is drivingly connected to the screw 52. A speed reducer 54 is connected between the driving motor 51 and the screw 52 for better driving the slide plate 3. The nut 53 is attached to the base plate 31. The screw 52 is provided along the direction of arrangement of the frame 1. The driving motor 51 rotates to drive the sliding plate 3 to slide through the screw pair.

The bed frame 1 is provided with a guide wheel 11 at the head of the bed, the guide wheel 11 being located at one side of the sliding plate 3. The back plate 2 is hinged on one end of the bed plate 32 close to the guide wheel 11. The backboard 2 is provided with a jacking boss 21 in cooperation with the guide wheel 11, so that when the backboard 2 moves to one side of the guide wheel 11, the guide wheel 11 rolls along the jacking boss 21 and the guide wheel 11 jacks up the backboard 2 gradually. The surface of the jacking boss 21 for the guide wheel 11 to roll is a jacking surface. In practice, when the backboard 2 is laid flat, one end of the backboard 2 close to the bed head is placed on the guide wheels 11 and supported by the guide wheels 11; meanwhile, the height of the jacking surface gradually inclines and descends from the bed head to one end of the bed tail.

In use, the driving motor 51 is turned on, so that the sliding plate 3 moves toward the guide wheels 11 along the frame 1. In this process, the sliding plate 3 pushes the back plate 2 to move toward the guide wheels 11. The cooperation of the jacking bosses 21 and the guide wheels 11 enables the back plate 2 to be gradually jacked up to stand up. Meanwhile, in this process, the footboard 4 slides with respect to the sliding plate 3. The footboard 4 gradually protrudes out of the receiving gap 33. After the bed is lifted, the patient can place the feet on the bed tail plate 4, and the use is convenient.

When the bed needs to be lowered, the driving motor 51 rotates reversely to move the sliding plate 3 back, so that the back plate 2 is lowered, and the bed tail plate 4 is automatically collected into the collecting gap 33. In practice, a plurality of buttons may be provided at the frame 1. Including a raise button and a lower button. The patient can conveniently operate the lifting of the bed when lying on the bed.

In this embodiment, the frame 1 is provided with a guide groove parallel to the screw 52. The notch of the guide groove is smaller than the inside of the guide groove. The base plate 31 is provided with a guide bar 312 in cooperation with the guide groove such that one end of the guide bar 312 is restricted to and can slide along the guide groove. In practice, the guide groove includes a square groove 12 and a top plate 121 disposed on top of the square groove 12. The end of the guide rod 312 extending into the guide groove is provided with a locking wheel 122 in cooperation with the top plate 121. The locking wheel 122 abuts the lower surface of the top plate 121. The guide bar 312 and the guide groove cooperate to effectively prevent the sliding plate 3 from arbitrarily sliding on the frame 1. At the same time, the engagement of the locking wheel 122 and the top plate 121 also prevents the guide bar 312 from being separated from the guide groove, thereby preventing the sliding plate 3 and the back plate 2 from being separated from the frame 1.

In this embodiment, the driving motor 51 is further provided with a power-off internal contracting brake. When the back plate 2 is lifted to the proper position, the driving motor 51 is turned off. At this time, the driving motor 51 automatically locks the rotating shaft to prevent the backboard 2 from sliding downwards.

In this embodiment, the upper surface of the bed tail plate 4 is provided with a sponge pad. This makes the patient's feet more comfortable when placed on the footboard 4.

In this embodiment, two bedrails are also included. The bed bars are arranged on the bedstead 1 and are positioned at two sides of the bedstead 1. The bedstead 1 comprises a plurality of vertical telescopic rods arranged on the bedstead 1 and cross rods arranged on the top ends of the telescopic rods. The bed fence can be folded by pressing the cross bar downwards; the bed fence can be lifted by pulling the cross bar upwards. Is convenient to use.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
