Description

A special wheelchair for nursing beds

technical field

The invention relates to the field of elderly care and assistance for the disabled, and is especially suitable for the elderly, infirm, disabled, paralyzed and semi-paralyzed.

Background technique

There are many types of smart wheelchairs, which are designed to provide assisted rehabilitation, living, rest and activities within a certain range for the elderly, infirm or disabled. The ability of the elderly to move by themselves is relatively poor, especially the frequent transfer from bed to wheelchair and from wheelchair to bed is a relatively big trouble in life. With the birth of various nursing beds, in order to meet the needs of the care recipients Space transfer, the change of sleeping and sitting positions, toilet care and other issues, special wheelchairs for nursing beds are also urgently needed to be developed.

Contents of the invention

In order to develop a special wheelchair for nursing beds, the present invention changes the integrated structure of the conventional intelligent wheelchair, and makes the seat body and the mobile chassis into relatively independent modules. The main part of the seat can complete the automatic docking action with the bed body of the nursing bed, and the mobile chassis part can be separated from the main part of the seat under the action of the traction mechanism, providing sufficient space for the nursing device to meet the needs of the nursing device for collecting, washing, Integration of multiple functions such as drying and disinfection.

The technical solution adopted by the present invention to solve the technical problem is: a special wheelchair facing the nursing bed, including the main body part of the seat, a traction mechanism, and a mobile chassis. The traction mechanism includes the traction main part and the mechanical interface. The traction mechanism relies on the torque output by the motor to drive the gear synchronous belt, and then connects the mobile chassis through the mechanical interface to make the mobile chassis move in the predetermined direction of the traction guide mechanism. The mobile chassis is composed of a chassis frame, omnidirectional casters, a guiding mechanism that cooperates with the main part of the seat, and a locking mechanism. After the mobile chassis and the main part of the seat are docked, a complete wheelchair is formed, which can be moved under the push of the nursing staff. For a powered chassis, after the chassis is docked with the main body of the seat, the movement of the wheelchair can be controlled through the operating lever. When the nursing bed is in the bed-chair combination state, that is, the non-wheelchair is in the state of moving out, the locking mechanism is opened, and the chassis is separated from the seat. After the traction mechanism is docked with the mobile chassis, the chassis is dragged by the traction mechanism to separate from the main part of the seat. And move to the designated position. At this time, the nursing device moves to the original chassis position, and completes the docking with the bed body, and the multifunctional intelligent toilet can be used. For powered chassis, after the chassis is separated from the seat, it will move to the designated position by itself.

The beneficial effect of the present invention is that the present invention not only solves the problem of the nursing person transferring from the bed to the wheelchair through a special wheelchair facing the nursing bed, but also solves the problem of insufficient space at the bottom of the traditional seat. The space is small, and the traditional bed and chair can not realize the functions of perfect defecation treatment and post-defecation care due to the space limitation after having the seat movement function. Using this solution can perfectly solve the conflict between the chassis mechanism and the nursing device.

【Example】

The invention discloses a special wheelchair facing a nursing bed, which includes a seat main part, a traction mechanism, and a mobile chassis. The traction mechanism includes a traction main part and a mechanical interface. Partially matched guide mechanism and locking mechanism, the traction mechanism is installed on the left and right sides of the bed body, when the seat travels to the designated position of the bed body, the locking mechanism is opened, the chassis and the seat are separated, and the traction mechanism and the mobile chassis After docking, the chassis is dragged by the traction mechanism to separate from the main body of the seat. At this time, the nursing device moves to the designated position and docks with the bed body. The invention not only solves the problem of transferring the nursing person from the bed to the wheelchair, but also solves the problem that the nursing device of the nursing bed cannot realize various relatively perfect functions of the existing intelligent toilet due to the defect of small space.

The special wheelchair facing the nursing bed includes traction mechanism 1, traction mechanism main body 2, mechanical docking port 3, mobile chassis 4, omnidirectional wheels 5, chassis and seat docking device part 6, seat main part 7, corner motor assembly 8, Backboard 9, seat plate 10, leg plate 11, foot plate 12, electric locking mechanism 13, manual locking mechanism 14, elevating mechanism 15, guiding mechanism 16. The traction mechanism 1 is composed of the traction mechanism main body 2 and the mechanical docking port 3. The traction mechanism main body 1 is installed on the left and right sides of the bed through 4 connecting plates. Driven by the motor, the gear synchronous belt drags the mechanical docking port 3 The connecting part of the move. The mobile chassis 4 includes omni-directional wheels 5, guiding mechanism 16, electric locking mechanism 13, manual locking mechanism 14, guiding mechanism 16 ensures the accurate docking position, and waits for the guiding mechanism 16 to move to an appropriate position, and the electric locking mechanism 13 starts to work , so that the seat plate of the mobile chassis 3 and the seat main body 7 is locked to form a stable wheelchair shape. The seat main part 7 includes a corner motor assembly 8, a backboard 9, a seat board 10, a leg board 11, and a foot board 12. When performing a back-lifting action during sitting posture adjustment, the corner motor assembly 8 drives the backboard 9 to rotate relative to the seat board 10 , stop after reaching the ideal position. Leg bends and leg raises are performed on the same principle. After stopping the movement, the posture is maintained by the power-off self-locking force of the corner motor assembly itself. When the care receiver needs to transfer in space, the nursing device moves out from one side of the bed body, and the mobile chassis 3 moves to the original position of the nursing device 3 under the action of the traction mechanism 1, and docks with the seat main body 5 After that, it can be separated from the bed body and moved easily under the push of the nursing staff. For a powered chassis, the movement can be completed under the care receiver's own control. After the seat returns to the bed body, the docking of the bed chair and the switching of the nursing device 3 and the mobile chassis 3 can be completed according to the reverse order of separation.

In this embodiment, the above-mentioned traction mechanism 1 and mobile chassis 3 are used when the chassis has no power. When a powered chassis is used, the traction mechanism can be omitted. The specific implementation method is not limited.
