The electric bed in the prior art can help people to lie down to sit upright, but has no function of standing and boosting, and has no function of helping people with insufficient leg and waist strength to stand, and the people can stand from a sitting position to a standing position by external help.

Disclosure of Invention

The invention aims to provide a power-driven booster bed, which mainly solves the problem that the old, weak, sick and disabled people with insufficient leg and waist strength are difficult to get up.

The power boosting bed comprises a bed frame, a seat plate is movably connected to the bed frame, a seat plate power mechanism for driving the seat plate to move is further arranged, and the moving range of the seat plate comprises a sleeping position, a sitting position and a standing position.

The sitting position and the standing position refer to the positions of the buttocks of the user opposite to each other when the user sits or stands up, and if the seat plate is positioned at the standing position, the seat plate is tightly attached to the buttocks of the user who stands. The standing position is not absolutely a position in which the user stands upright, and a position in which the user is helped to stand inclined from a sitting position can also give sufficient help, and a user whose partial leg and waist strength is not completely lost can self-go from an inclined standing position to a normal standing position. The scheme can help a user to enter a standing state from a sitting posture, the seat plate power mechanism provides power for the seat plate to move within a moving range in the working process, and the movement of the seat plate can help the user sitting on the seat plate to enter the standing posture.

Furthermore, the bed frame is hinged with the seat plate, and the seat plate is kept horizontal when in a seat position. The seat plate is driven to rotate to help a user to get up from a sitting posture to a standing posture, the seat plate can be vertically arranged at 90 degrees in the standing position (behind the hip of the user in the standing posture), and the seat plate can achieve similar effects when the seat plate is close to 90 degrees in the standing position.

Furthermore, the operation of the seat power mechanism is driven and controlled by the controller, the bed frame is movably connected with a back plate and leg plates, the back plate and the leg plates can move to a sleeping position, a sitting position or a standing position under the action of the power mechanism, the back plate and the leg plates are provided with touch devices, and the touch devices touch the controller to control a working power supply for connecting the seat power mechanism when the back plate and the leg plates are in the sitting position.

In this scheme, if the back plate and the leg plate are not in the sitting position, the working power supply of the seat plate power mechanism is not switched on, and the seat plate cannot be driven to move. Therefore, the seat plate can be prevented from moving when a user lies down, and potential safety hazards to the user are avoided.

Furthermore, the seat board power mechanism is an electric push rod. The driving may be performed by a gear rack, a sprocket, or the like.

Detailed Description

The following is further detailed by way of specific embodiments:

the first embodiment is substantially as shown in figures 1 and 2, wherein the reference numerals comprise: a bed frame 1, a back plate 2, a seat plate 3 and a leg plate 4.

The bedstead is a cubic metal frame, and the back plate, the seat plate and the leg plate are all hinged on the bedstead and driven by the electric push rod. Particularly, the back plate is hinged at the middle part of the upper surface of the bed frame and can rotate between 0 and 90 degrees; the seat board is hinged at the right end of the upper surface of the bed frame (namely the end of the leg of the user), and can also rotate between 0 and 90 degrees; the leg plate is hinged on the upper end of the right surface of the bed frame, the hinged part is closer to the hinged part of the seat plate, and the leg plate can rotate between 0 and 90 degrees. When the user needs to stand up, the electric push rod can drive the back plate and the leg plate to rotate, and the user can adjust the sleeping posture to the sitting posture. When the sitting posture needs to stand after being stabilized, the sitting plate can be driven by the electric push rod, the sitting plate can be rotated to help a user to stand, and the user can hold the handrail tightly and slowly stand.

In another embodiment, the difference from the previous embodiment is that a standing button is provided on the armrest on one side of the bed frame, and the standing button is connected to the working circuit of the electric push rod of the seat plate. The back plate and the leg plates are provided with touch devices, namely, the back plate and the leg plates touch the travel switches when entering the seat, and the travel switches are connected with the power circuits of the electric push rods corresponding to the seat, so that the electric push rods corresponding to the seat are connected with the working circuits only when the back plate and the leg plates enter the end points of the seat, and the back plate and the leg plates can be driven. The travel switch is mainly used for preventing misoperation of users and others.

In another embodiment, the difference with the previous embodiment is that the mattress is attached to the bed frame by the patch, the mattress on the foot rest needs to be stretched and contracted when being bent to 90 degrees, two rubber bands are arranged at the end of the mattress on the foot rest, and the other end is hung at the end under the foot rest to play a role in stretching compensation.

In another embodiment, the difference from the previous embodiment is that the rotation angle of the back plate can exceed 90 °, for example, 120 °, so that the top end of the back plate is sewed with a back cushion (which can be a horizontally placed cylinder), and the back cushion can contact the back of the user, thereby realizing some support for the user to stand, and simultaneously providing support when the user falls backwards (for example, falls backwards accidentally, or needs to sit down in a standing state), and improving the safety factor of the device.

In the above embodiments, the seat plate does not need to be rotated, and can be moved vertically and linearly or in other more complex curved motions, so that the same boosting effect as the present solution can be achieved. The electric push rods corresponding to the back plate, the seat plate and the leg plate can be used for work control by using the controller. The travel switches can also be replaced by rotary encoders to detect the postures of the movable plate members.

The above description is only an embodiment of the present invention, and the general knowledge of the known specific structure and/or characteristics in the solution is not described too much, and the power driving part can refer to the description in the prior art, including the content described in chinese patent publication No. CN 106618889A. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
