Description

Electric bed with sliding half-folding device

The present invention relates to a foldable bed frame, in particular to an electric bed with a sliding half-folding device.

Referring to Fig. 1, the electric bed with the function of lifting the waist disclosed by the New Patent Publication No. M525120U of the Republic of China comprises a bed frame unit 10, and a bed frame unit 10 which can be slid along a head-to-tail direction D through several rollers 111 base frame 11, a headrest frame 12 pivotally connected to the head side of the base frame 11, a linkage unit 13 composed of several connecting rods and pivotally connected to the headrest frame 12 and the bed frame unit 10, and A push rod electric cylinder 14 connected to the linkage unit 13 and used to drive the linkage unit 13 . The push rod electric cylinder 14 can drive the interlocking unit 13 to drive the head and back frame 12 to swing upwards and to drive the base frame 11 to slide towards the head side, so that the electric bed with the function of supporting the waist is adjusted to a sitting position.

However, since the electric bed with the function of supporting the waist cannot be folded in half, it occupies a large area and is not convenient for storage, so there is still room for improvement.

Therefore, the purpose of the present invention is to provide an electric bed with a sliding folding device that is convenient for storage.

Therefore, the electric bed with a sliding half-folding device of the present invention includes a bottom frame unit, a sliding frame unit, a bed board unit and a driving link mechanism. The bottom frame unit includes a first frame body and a second frame body pivotally connected in half along a front-rear direction.

The sliding frame unit is slidably arranged on the base frame unit along the front-rear direction. The sliding frame unit includes a first sliding frame and a second sliding frame. The first sliding frame is disposed on the top side of the first frame body along a top-bottom direction and can slide relative to the first frame body. The first sliding frame has a plurality of first rollers slidably arranged on the first frame body. The second sliding frame is pivotally connected to the first sliding frame in a foldable manner, is arranged on the top side of the second frame body along the top-bottom direction, and can slide relative to the second frame body. The second sliding frame has a plurality of second rollers slidably disposed on the second frame body. The bed board unit can be movably arranged on the sliding frame unit, and the bed board unit includes a front bed board group and a rear bed board group pivotally connected in half along the front-rear direction. The drive link mechanism is driven by electricity to drive at least one of the front bed board set and the rear bed board set to yaw relative to the base frame unit, and to drive the sliding frame unit to slide relative to the base frame unit.

The electric bed with sliding half-folding device can be switched between an unfolded state and a double-folded state. In the unfolded state, the first frame body and the second frame body are unfolded in the front-rear direction. In the folded state, the first frame body, the second frame body, the first slide frame, the second slide frame, the front bed board set and the rear bed board set are stacked in the top-to-bottom direction.

The effect of the present invention is: the present invention can switch between the unfolded state and the folded state, and in the folded state, the first frame body, the second frame body, the first slide frame, and the second slide frame . The front bed board group and the rear bed board group are stacked in the direction of the top and bottom, which can shorten the overall length and reduce the occupied area, so it is convenient for storage.
