Detailed ways

Specific embodiments of the present invention will be described below.

The present invention proposes a wheelchair device that can be docked with a nursing bed to solve the technical problems of bedridden patients' basic activities and simple travel. Specifically, in this embodiment, the mechanism includes a wheelchair body, a height adjustment mechanism, and a shape transformation mechanism. Mechanism, combined with the nursing bed locking mechanism to form the wheelchair device that can be docked with the nursing bed, the wheelchair can be locked, docked and separated from the nursing bed through the locking device, and the wheelchair device can be connected through the posture change mechanism when docking Flattening, it is convenient to transfer the patient from the nursing bed to the wheelchair device. At the same time, after the wheelchair is separated from the nursing bed, the wheelchair is refolded and transformed into a wheelchair form by the posture conversion mechanism, so as to facilitate the patient's movement and travel needs. The device includes a lifting mechanism, and the lifting structure is used to change the height of the wheelchair device to achieve the purpose of adapting to the height of different nursing beds.

In this embodiment, the wheelchair device body includes a base 101, a lifting mechanism 102 and a support 103, the lifting mechanism 102 is installed on the base 101, and the chair surface 3 is installed on the support 103, and the height of the support can be adjusted by the lifting mechanism 102 , and then adjust the height of the chair surface 3 to realize the lifting function of the wheelchair device. A cushion is installed on the chair surface 3 to improve the comfort experienced by the patient.

In this embodiment, the lifting mechanism 102 includes a link mechanism and a push rod 105, the lifting mechanism is installed on the base, the push rod motor 105 is installed on the base 101, and is connected with the link mechanism, the link mechanism includes a rotating shaft 104 and The connecting rod, the connection between the rotating shaft 104 and the base 101 can be rotated. One end of the connecting rod is connected with the rotating shaft 104, and the other end is fixedly connected with the bracket 103. The height position of the bracket is changed through the rotation process of the connecting rod, thereby changing the height of the chair panel. high.

In this embodiment, the push rod motor 105 pushes the connecting rod to move through telescopic action. When the push rod motor stretches outward, it pulls the connecting rod to move, and the connecting rod will rotate around the rotating shaft 104, thereby adjusting the distance between the top of the connecting rod and the bottom surface. height, so that the bracket 103 is raised; when the push rod motor shrinks inwardly, the connecting rod rotates around the axis of rotation, thereby reducing the height of the top of the connecting rod from the bottom surface, so that the bracket 103 is lowered, thereby changing the height of the wheelchair panel. The push rod motor drives the link mechanism to move, so as to realize the height of the panel of the wheelchair device, which facilitates the matching of the height of the wheelchair device and the nursing bed, thereby facilitating the movement of the patient from the nursing bed 4 to the wheelchair 1 .

In this embodiment, the docking locking arrangement 2 between the wheelchair 1 and the nursing bed 4 is an electromagnetic adsorption structure, a part of the electromagnetic adsorption part is fixed on the side of the wheelchair, and the other part is fixed on the corresponding position on the side of the nursing bed. The role of electromagnetic force locks the wheelchair device and the nursing bed firmly together. When the wheelchair and the nursing bed need to be docked and locked, the electromagnetic adsorption device 2 is energized, so that the electromagnetic adsorption device 2 generates electromagnetic force to make it firmly locked with the nursing bed. When the wheelchair device needs to be separated from the nursing bed, you only need to power off the electromagnetic adsorption device, so that the electromagnetic adsorption device loses its electromagnetic force. At this time, the wheelchair device and the nursing bed can be separated from each other to realize the free movement of the wheelchair device, and then pass The transformation mechanism transforms the wheelchair from the flattened state to the wheelchair form, thereby realizing the use requirement of free movement.

In this embodiment, the wheelchair device includes a wheelchair bracket, a wheelchair deck and a posture changing mechanism. A plurality of universal wheels 106 are installed on the bottom of the wheelchair bracket for moving the wheelchair. The wheelchair panel and the posture changing mechanism are installed on the wheelchair bracket. Above, the posture changing mechanism is connected with the wheelchair board, and the shape of the wheelchair board can be changed through the posture changing mechanism, thereby transforming the wheelchair device into a flattened shape or folded into a wheelchair shape.

In this embodiment, the wheelchair board includes a back board 301, a hip board 302 and a leg board 303, the back board 301 is connected to one side of the hip board 302, and they can rotate between them, and the leg board 303 and the hip board 302 The other side is connected, and they can also rotate between them.

In this embodiment, the posture transformation mechanism link mechanism and push rod motor, wherein the link mechanism is connected between the push rod motor 305 and the leg plate, and another set of link structure and push rod motor 304 are connected between the hip plate and the back plate Between, the link mechanism is connected in rotation with the push rod motor, and the top is connected in rotation with the backboard.

In this embodiment, the push rod motor can realize telescopic movement, and by driving the linkage mechanism, the wheelchair deck can be converted by 90°, so as to realize the conversion between the flattened state of the wheelchair and the sitting posture of the folded wheelchair. A push handle is provided at the bottom of the backboard, and after the wheelchair board is deformed into a wheelchair form through posture transformation, the handle can be pushed to push the wheelchair to move.

In this embodiment, cushions are provided on the board of the wheelchair to improve the comfort of the patient.

In this embodiment, foldable handrails 107 are installed on both sides of the wheelchair board to protect the patient. When docked with the nursing bed, the handrails 107 can be folded and hidden. When the wheelchair posture is converted into the sitting posture wheelchair state, the armrest 107 can be lifted at this moment to prevent the patient from falling from the side and protect the patient.

The invention proposes a wheelchair device that can be docked with a nursing bed, including: a wheelchair lifting mechanism, a posture changing mechanism, and an electromagnetic fixing device for the nursing bed, etc. The wheelchair lifting mechanism can adjust the height of the wheelchair to match the nursing bed, and the posture changing mechanism Transform the wheelchair into a horizontally flattened form or a folded form in a sitting position. The locking mechanism with the nursing bed can be firmly locked with the nursing bed. Through the connecting rod structure and the push rod motor, the posture switching and height lifting can be realized, ensuring the function On the basis of the realization of the wheelchair, the weight and difficulty of use of the entire wheelchair device are reduced as much as possible by optimizing the structure. The lifting function, posture change and electromagnetic locking and docking function of the wheelchair are integrated, which can meet the needs of patients in home care and hospitals. Most of the needs, easy to operate and adapt to a wide range.

Except for the technical features described in the specification, the rest of the technical features are known to those skilled in the art. In order to highlight the innovative features of the present invention, the rest of the technical features will not be repeated here.
