[0046] The bed body referred to in the present invention can be used as a hospital bed, a nursing bed and an operating bed, and is suitable for various usage scenarios of patients with limited mobility.

[0047] As attached Figure 1-17 As shown, the present invention provides a bed-chair device, comprising a fixed bed body 1, a movable bed-chair 2 and a bed body support and limiting mechanism 3;

[0048] The fixed bed body 1 includes a fixed frame 11 and a bed board 12. Figure 3The fixed frame 11 includes a bed frame 111 and a bed foot 112 arranged under the bed frame 111. The bed foot 112 is used to support the bed frame 111 to a certain height. The bed frame 111 includes a horizontal frame 1111 and two vertical frames 1112 arranged at both ends of the horizontal frame 1111. The two vertical frames 1112 are preferably arranged perpendicular to the horizontal frame 1111. The horizontal frame 1111 and the two vertical frames 1112 enclose a bed installation plane 1113. The opposite side of the horizontal frame 1111 is an entrance 1114 for the mobile bed chair 2. In this way, the mobile bed chair 2 can enter the bed installation plane 1113 through the entrance 1114 and form a larger bed body in combination with the bed frame 111;

[0049] refer to Figure 13-16 The mobile bed chair 2 has a chair shape and a bed shape, and can be used as a wheelchair or as a bed;

[0050] In one embodiment, the bed board 12 is hingedly mounted on the horizontal frame 1111, and the bed board 12 has a rotation stroke toward and away from the bed body mounting plane 1113. Figure 4-Figure 5 , that is, the bed plate 12 can be rotated to the bed body installation plane 1113 and be coplanar with the bed body installation plane 1113, and then the entire fixed bed body 1 can be used independently as a bed body, refer to Figure 6-Figure 7 In addition, the bed board 12 can also be rotated toward the bottom of the bed, thereby freeing up space on the bed body installation plane 1113; at this time, the bed board 12 is not on the bed body installation plane 1113, and the bed-shaped movable bed chair 2 can be embedded in the bed body installation plane 1113, and then the movable bed chair 2 and the fixed bed body 1 are combined to form a bed body for use. In this embodiment, flexible pads can be set on the panel of the movable bed chair 2 and the bed board 12, so that they can be used directly without laying a quilt core separately.

[0051] In this embodiment, the mobile bed chair 2 can be used as a wheelchair and also as a bed, and is suitable for patients with limited mobility. When the patient needs to move, the wheelchair can be switched to use, and when the patient needs to rest or transfer, the bed can be switched to use;

[0052] Among them, the fixed bed body 1 can be used as a bed body alone, and can also be used as a bed body in combination with the mobile bed chair 2. When used in combination, the bed-shaped mobile bed chair 2 can be fixed in position to improve the position fixing stability of the mobile bed chair 2. At the same time, the bed surface area of ​​the bed can be expanded, thereby improving the patient's sleeping comfort and the convenience of the doctor's operation. When the two are used alone, the fixed bed body 1 can be used independently as a bed body to avoid wasting space in the medical facility and ensure the number of beds in the medical facility. When the mobile bed chair 2 is used alone, it can be used as a wheelchair alone or as a bed body alone, which can facilitate the movement and transfer of patients and ensure the appropriate width size of the mobile bed chair 2 with good passability.

[0053] In addition, the hinged setting of the bed board 12 can be quickly and flexibly coplanar with and separated from the bed installation plane 1113 without affecting the use effect of the fixed bed 1 and the mobile bed chair 2. When the patient needs rest and surgery, the bed board 12 can be quickly separated from the bed installation plane 1113. At the same time, the mobile bed chair 2 carrying the patient can be quickly embedded in the bed installation plane 1113 to complete the combination, thereby gaining time for surgery.

[0054] In this embodiment, the fixed bed body 1 also includes a driving member I for driving the bed board 12 to rotate. The driving member I can be a linear driving member whose two ends are respectively hinged on the cross frame 1111 and the bed board 12, such as a cylinder, a hydraulic cylinder or an electric push rod. The driving member I can also be a motor arranged at the hinged position of the bed board 12, thereby providing active control of the bed board 12, reducing the difficulty of use for the operator, and increasing the speed of state switching.

[0055] refer to Figures 8-12 In another embodiment, the bed board 12 is a rolling bed board arranged on the horizontal frame 1111, and the two vertical frames 1112 are provided with guide rails 11121 on opposite sides of the rolling bed board, and the rolling bed board has an extension stroke along the bed mounting plane 1113 and a retraction stroke to the horizontal frame 1111, that is, the rolling bed board can be extended to the entire bed mounting plane 1113 and be coplanar with the bed mounting plane 1113, so that the entire fixed bed 1 can be used independently as a bed. In addition, the rolling bed board can also be retracted onto the horizontal frame 1111, thereby freeing up space on the bed mounting plane 1113; at this time, the bed board 12 is not on the bed mounting plane 1113, and the bed-shaped movable bed chair 2 can be embedded in the bed mounting plane 1113, and then the movable bed chair 2 and the fixed bed 1 are combined to form a bed for use.

[0056] In this embodiment, the same effect is achieved as in the embodiment in which the bed board 12 is hingedly mounted on the horizontal frame 1111. In addition, in this embodiment, the bed board 12 does not occupy the space under the bed when in the rolled-up state. At the same time, the width of the bed mounting plane 1113 can be smaller than the height of the bed foot 112, thereby reasonably controlling the height and width of the bed. In addition, guide rails 11121 cooperating with the rolling bed board are provided on the two longitudinal frames 1112, which can ensure the structural strength of the entire bed board 12 and meet the strength requirements for independent use of the fixed bed body 1. In addition, in the rolled-up state of the rolling bed board, the guide rails 11121 can be used to support the two ends of the mobile bed chair 2 in the shape of a bed, thereby improving the strength requirements of the bed body when used in combination.

[0057] refer to Figure 11-12 In this embodiment, a rolling bed board installation cavity 11111 is provided in the horizontal frame 1111, and an opening 11112 is provided in the horizontal frame 1111 facing the guide rail 11121. By providing the rolling bed board installation cavity 11111 in the horizontal frame 1111, it is convenient to store the rolling bed board in the rolled-up state, thereby improving the overall aesthetics of the bed body.

[0058] In this embodiment, the fixed bed body 1 also includes a roller shutter drive 13 arranged in the roller shutter bed board installation cavity 11111 to drive the roller shutter bed board to unfold and reel in. The roller shutter drive 13 can be a reeling roller to improve the automation of unfolding and reeling of the bed board 12 and increase the switching speed. In addition, a pull rope can be arranged on the end face of the roller shutter bed board. The pull rope is arranged along the guide rail 11121 and the end is connected to the drive roller. The pull rope drives the unfolding of the roller shutter bed board, and the reeling roller drives the reeling of the roller shutter bed board. Here, the reeling roller and the pull rope are common driving methods of the roller shutter structure and will not be described in detail here.

[0059] In this embodiment, the rolling bed board includes a plurality of parallel beams 121, and the beams 121 are arranged parallel to the cross frame 1111. Every two beams 121 are connected by a flexible connector 122, thereby realizing the retraction and unfolding of the bed board 12. In addition, the beams 121 themselves meet sufficient rigidity requirements and can support adult patients. In addition, the strength can be improved by combining with the bed support limit mechanism 3.

[0060] In one embodiment, the bed support and limiting mechanism 3 is arranged at the bottom of the longitudinal frame 1112. The bed support and limiting mechanism 3 can support and limit the bed board 12 and the bed body of the bed-shaped movable bed chair 2, thereby improving the fixing stability of the bed board 12 and the bed-shaped movable bed chair 2, so as to improve the safety performance and structural strength of the bed.

[0061] The present invention provides two implementation methods for the bed support and limiting mechanism 3, one of which is:

[0062] The bed support and limiting mechanism 3 includes a driving member II 32, a connecting rod 33 and a plurality of limiting support plates 31. The plurality of limiting support plates 31 are hingedly arranged in parallel on the longitudinal frame 1112 of the fixed bed 1, and have a stroke of moving toward and away from the bed installation plane 1113. When set toward the bed installation plane 1113, the limiting support plates 31 limit the bottom of the bed board 12 and the bottom of the bed-shaped movable bed chair 2 to improve its structural strength and position fixity. A plurality of limiting support plates 31 are provided with an articulated seat 311 at one end facing the longitudinal frame 1112, and the connecting rod 33 is hinged to the plurality of articulated seats 311. The driving member II 32 is fixedly arranged on the longitudinal frame 1112, and the output end of the driving member II 32 is connected to the connecting rod 33. The driving member II 32 has a moving stroke for driving the connecting rod 33 to move, thereby driving the plurality of limiting support plates 31 to rotate synchronously.

[0063] In this embodiment, the limiting support plates 31 can rotate synchronously, thereby improving the synchronization of multiple limiting support plates 31, and further supporting and limiting the width direction intervals of the bottom of the bed board 12 and the bottom of the bed-shaped movable bed chair 2, while improving the switching efficiency and strength of the support and limit. In addition, multiple limiting support plates 31 are connected by a connecting rod 33 and driven by a driving member II 32, which can reduce the number of driving members II 32 and reduce the cost of the device.

[0064] In this embodiment, a rotating handle 35 is provided on at least one limit support plate 31, and the rotation of multiple limit support plates 31 can be manually controlled by operating the rotating handle 35. When the driving part II 32 is powered off, the bed support limit mechanism 3 can still be used normally.

[0065] In this embodiment, the limiting support plate 31 is tilted downward at one end away from the hinge, so that the limiting support plate 31 is easily inserted into the bottom of the bed board 12 or the bed-shaped movable bed chair 2, thereby improving the convenience of support and limiting.

[0066] In this embodiment, the driving member II 32 is a steering gear, which can drive the connecting rod 33 to move tiltingly, so as to realize driving the multiple limiting support plates 31 to rotate synchronously.

[0067] In this embodiment, a receiving groove 11122 for receiving the limiting support plate 31 is provided on the longitudinal frame 1112 . When the limiting support plate 31 is not needed, it can be received in the receiving groove 11122 to avoid occupying the space of the bed installation plane 1113 .

[0068] refer to Figure 2In this embodiment, a limit rod 34 is provided at the bottom of the bed body of the bed-shaped movable bed chair 2. After the limit support plate 31 rotates, it abuts against the limit rod 34, and the limit support plate 31 limits the movement of the bed-shaped movable bed chair 2 in the direction away from the horizontal frame 1111. That is, while supporting the movable bed chair 2, the limit support plate 31 can limit the movement of the movable bed chair 2 toward the entrance 1114, thereby improving the fixed stability of the movable bed chair 2.

[0069] In another embodiment, one or more bed support and limiting mechanisms 3 may be provided, and each support and limiting mechanism 3 is independently driven by a driving member II 32 .

[0070] The present invention also provides another implementation of the bed support and limiting mechanism 3:

[0071] refer to Figure 2 The bed support and limit mechanism 3 includes a limit support frame 36 arranged at the bottom of the longitudinal frame 1112. The bottom of the bed of the mobile bed chair 2 in the bed form is provided with a mosaic frame 37 corresponding to the limit support frame 36. The mosaic frame 37 can be embedded in the limit support frame 36 to limit the movement of the mobile bed chair 2 in all directions. In this embodiment, the mobile bed chair 2 needs to enter the bed installation plane 1113 from the entrance 1114 when in the chair form. In the process of switching to the bed form, the mosaic frame 37 is inserted into the limit support frame 36 to complete the limit support. In this embodiment, the limit support frame 36 is a frame structure, which can play a good supporting and limiting role, and the mosaic frame 37 can be used as a push handle when the mobile bed chair 2 is in the chair form, which is convenient for nursing staff to accompany the patient to move and push the mobile bed chair 2 in the chair form.

[0072] In one embodiment, the mobile bed chair provided by the present invention includes a mobile platform 21, a backrest 22 hingedly arranged at one end of the mobile platform 21, and a footrest 23 hingedly arranged at the other end of the mobile platform 21. By controlling the angles of the backrest 22 and the footrest 23, the mobile bed chair can be switched into a chair form or a bed form. That is, when the backrest 22, the plane 2111 of the mobile platform 21, and the footrest 23 are coplanar, the backrest 22, the plane 2111, and the footrest 23 are combined to form a bed surface, and the mobile bed chair 2 is in a bed form; when the footrest 23 is coplanar, the backrest 22, the plane 2111, and the footrest 23 are coplanar, and the backrest 22, the plane 2111, and the footrest 23 are combined to form a bed surface. When the plane 2111 is rotated downward by a certain angle and the backrest 22 is rotated upward by a certain angle relative to the plane 2111, the plane 2111 becomes a seat plate for supporting the patient's buttocks, the backrest 22 is used to support the patient's back, and the footrest 23 is used to support the patient's legs. In a preferred embodiment, a torsion spring is provided at the hinge between the backrest 22 and the movable platform 21. The torsion spring can eliminate the shaking of the backrest and stabilize the state of the backrest. At the same time, the torsion spring can help increase the lifting force of the driving member III 24 and reduce the load of the driving member III 24.

[0073] The mobile platform 21 includes a platform frame 211 and at least four running wheels 212 arranged in a rectangular array at the bottom of the platform frame 211. The steering of the running wheels 212 is independently controllable. In one embodiment, a steering platform can be installed on the bottom side of the platform frame 211, and the running wheels 212 are arranged on the steering platform. The steering of the running wheels 212 is controlled by controlling the steering platform, that is, the steering of the four running wheels 212 can be independently controlled, and at least two running wheels 212 are driving wheels, that is, at least one running wheel 212 is equipped with a driving motor to drive it to rotate and move.

[0074] The mobile bed chair 2 provided by the present invention adopts four independently controllable running wheels for steering, which greatly improves the passability of the mobile bed chair 2 and the direction control is flexible and changeable. Among them, the docking of the mobile bed chair 2 with the fixed bed body 1 can be automatic or manual. When the mobile bed chair 2 is used in combination with the fixed bed body 1, the mobile bed chair 2 can first move to the entrance 1114 position, and the mobile bed chair 2 and the fixed bed body 1 are parallel to each other, and then the automatic reset program is started to automatically calibrate the position, control the angle of the four running wheels 212 so that it faces the bed body installation plane 1113, so that the mobile bed chair 2 is directly moved horizontally to the bed body installation plane 1113 to complete the combination with the fixed bed body 1, which greatly improves the convenience of assembly. In addition, when the two diagonally opposite running wheels 212 are controlled to be set in the same direction, that is, when the four running wheels 212 are arranged in an X shape, the four running wheels 212 complete the movement self-locking, that is, the braking and position fixing of the mobile bed chair 2 can be completed without the need for an additional braking device.

[0075] The four running wheels 212 are all driving wheels, which can improve the power performance and steering effect of the mobile bed chair 2.

[0076] The mobile bed chair 2 also includes a driving member III 24 for driving the backrest 22 and the footrest 23 to rotate, thereby actively controlling the rotation of the backrest 22 and the footrest 23 and improving the switching efficiency. The driving member III 24 preferably adopts a cylinder, a hydraulic cylinder or an electric push rod whose two ends are hinged to the backrest 22 and the platform frame 211, and a cylinder, a hydraulic cylinder or an electric push rod whose two ends are hinged to the footrest 23 and the platform frame 211.

[0077] The footrest 23 includes a support plate 231 and a connecting plate 232 which are hinged in sequence. The other end of the connecting plate 232 is hinged to the mobile platform 21. A connecting rod 234 is hinged to one side of the support plate 231 and the connecting plate 232. The other end of the connecting rod 234 is hinged to the mobile platform 21. When the driving member III 24 drives the connecting plate 232 to rotate, the support plate 231 moves up and down in parallel under the drive of the connecting rod 234, so that the patient's feet can always move in parallel, thereby improving comfort.
