With cutting-edge technology and ingenious structural design, it creates a comfortable care environment for users, while reducing the workload of caregivers and improving the overall efficiency and quality of care.

[0003] Existing convertible assistive chairs commonly use a manual crank-rocker mechanism. Caregivers need to manually turn the crank and use the rocker to change the angle of the backrest or leg support parts of the chair. This mainly relies on human power and the simple lever principle. Some also use gear and rack transmission, where rotating the gear pushes the meshing rack, thereby adjusting the angle of the chair parts.

[0004] Existing convertible assistive chairs use manual cranks for adjustment. This method is not only cumbersome to operate, but also requires considerable force for each adjustment, making it strenuous. Furthermore, it cannot adjust the backrest and leg support angles according to the patient's physical condition or rehabilitation needs to achieve the most comfortable posture, thus affecting the patient's comfort and rehabilitation effect during use. Therefore, a convertible assistive chair is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a deformable nursing bed chair, which aims to improve the problem that the existing technology is difficult to operate and cannot adjust the backrest and leg support angles according to the patient's own physical condition or rehabilitation needs to achieve the most comfortable posture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A deformable assistive chair includes a seat cushion, a backrest rotatably connected inside the seat cushion, a leg support plate rotatably connected inside the seat cushion, a base fixedly connected to the lower surface of the seat cushion, casters fixedly connected to the lower surface of the base, an adjustment component provided on the upper surface of the base, and a folding component provided on the upper surface of the seat cushion.

The rotating plate is rotatably connected to the side wall of the connecting column. Connecting blocks are fixedly connected to the lower surfaces of the backrest and the leg support plate. One end of the rotating plate is rotatably connected inside the connecting block.

[0009] As a further description of the above technical solution:

[0010] The folding assembly includes a base plate, a rotating bar, and an armrest. The base plate is fixedly connected to the upper surface of the seat cushion, the rotating bar is rotatably connected inside the base plate, and the rotating bar is rotatably connected inside the armrest.

[0011] As a further description of the above technical solution:

[0012] The fixing frame has a sliding groove inside, and the side wall of the sliding block is slidably connected inside the sliding groove;

[0013] As a further description of the above technical solution:

[0021] As a further description of the above technical solution:

[0022] The sidewall of the card block is slidably connected in the through hole inside the fixed sleeve.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by activating the hydraulic rod below the backrest, the slider is pushed to slide, causing the rotating plate to rotate. This rotation is then pushed by the connecting block to rotate the backrest. By activating the hydraulic rod below the leg support plate, the slider is retracted and pulled to slide, causing the rotating plate to pull the leg support plate downward. This allows for the adjustment of the angles of the backrest and leg support plate according to individual needs. This solves the problem that some deformable assistive chairs use manual cranks for adjustment, which is laborious and difficult to operate. Furthermore, adjusting the backrest and leg support angles according to the patient's physical condition or rehabilitation needs to achieve the most comfortable posture affects the patient's comfort and rehabilitation effect during use. The above structure improves patient comfort.

[0025] 2. In this utility model, by pressing the pressing handle upward, the pressing plate slides upward inside the fixed frame, thereby squeezing the spring and causing the locking block to disengage from the fixed sleeve, thus releasing the fixing effect. At this time, by moving the handrail, the rotating bar can be rotated, thereby achieving the folding effect of the handrail, increasing the convenience and comfort of use.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a deformable assistive bed chair, including a seat cushion 1, a backrest 2 rotatably connected inside the seat cushion 1, a leg support plate 3 rotatably connected inside the seat cushion 1, a base 4 fixedly connected to the lower surface of the seat cushion 1, casters 5 fixedly connected to the lower surface of the base 4, an adjustment component on the upper surface of the base 4, and a folding component on the upper surface of the seat cushion 1; the adjustment component includes a hydraulic rod 7, a slider 8, a sliding block 9, a connecting column 10, and a rotating plate 11; a fixing frame 6 is fixedly connected to the upper surface of the base 4, and the side wall of the hydraulic rod 7 is fixed... The hydraulic rod 7 is fixedly connected to the side wall of the fixed frame 6. The output end of the hydraulic rod 7 is fixedly connected to the side wall of the slider 8. The slider block 9 is fixedly connected to both sides of the slider 8. The connecting column 10 is fixedly connected to the side wall of the slider block 9. The rotating plate 11 is rotatably connected to the side wall of the connecting column 10. The backrest 2 and the lower surface of the leg support plate 3 are both fixedly connected to the connecting block 12. The connecting block 12 is used to connect the rotating plate 11 and the backrest 2. One end of the rotating plate 11 is rotatably connected to the inside of the connecting block 12. The fixed frame 6 has a sliding groove 13 inside. The side wall of the slider block 9 is slidably connected to the inside of the sliding groove 13.

[0034] When adjusting the angle of the backrest 2 using this device, the hydraulic rod 7 located below the backrest 2 on the base 4 is activated. When the hydraulic rod 7 extends, it pushes the slider 8 to slide on the fixed frame 6. At the same time, the sliding blocks 9 on both sides of the slider 8 slide within the slide groove 13. The slide groove 13 and the sliding blocks 9 cooperate with each other to guide and stabilize the movement of the slider 8, preventing it from deviating. As the slider 8 moves, the connecting column 10 also moves, which drives the rotating plate 11 to rotate around the connecting column 10. This rotation pushes the backrest 2 to rotate around its rotational connection point with the seat cushion 1 through the connecting block 12, transmitting the rotational driving force of the rotating plate 11 to the backrest 2. Ultimately, the angle of the backrest 2 can be adjusted to meet the user's needs for different tilt angles, providing a comfortable leaning angle. Similarly, when adjusting the angle of the leg support 3, the hydraulic rod 7 below the corresponding leg support 3 is activated. At this time, the hydraulic rod 7 retracts, pulling the slider 8 to slide in the opposite direction. The reverse sliding of the slider 8 drives the rotating plate 11 to rotate in the opposite direction. During the reverse rotation of the rotating plate 11, the connecting block 12 on the lower surface of the leg support 3 is pulled. The connecting block 12 transmits the reverse rotation driving force of the rotating plate 11 to the leg support 3, causing the leg support 3 to move downward around its rotational connection point with the seat cushion 1, completing the adjustment of the angle of the leg support 3. Through this adjustment method, the angles of the backrest 2 and the leg support can be adjusted separately to achieve the most comfortable posture, improving the user's comfort on the equipment and reducing hand fatigue for medical staff.

[0035] Reference Figure 4The folding assembly includes a base plate 14, a rotating bar 15, and an armrest 16. The base plate 14 is fixedly connected to the upper surface of the seat cushion 1. The rotating bar 15 is rotatably connected to the inside of the base plate 14 and the armrest 16. A fixing sleeve 17 is fixedly connected to the side wall of one side of the rotating bar 15. A through hole is provided inside the fixing sleeve 17. A fixing frame 18 is fixedly connected to the lower surface of the armrest 16. A pressing handle 19 is provided inside the fixing frame 18. A spring 20 is provided inside the fixing frame 18. One end of the spring 20 is fixedly connected to the inside of the fixing frame 18, and the other end of the spring 20 is fixedly connected to the upper surface of the pressing handle 19. The side wall of the pressing handle 19 is slidably connected to the inside of the fixing frame 18. A locking block 21 is fixedly connected to the lower surface of the pressing handle 19. The side wall of the locking block 21 is slidably connected to the through hole inside the fixing sleeve 17.

[0036] When the armrest 16 needs to be folded, press the pressing handle 19 upwards. The pressing handle 19 slides inside the fixed frame 18. With the pressing action, it moves upwards and compresses the spring 20. During the compression process, the spring 20 stores elastic potential energy, which causes the locking block 21 fixed on the lower surface of the pressing handle 19 to slide out of the through hole inside the fixed sleeve 17. The locking block 21 engages with the through hole inside the fixed sleeve 17. In the normal state, the locking block 21 slides into the through hole, fixing the armrest 16 in the unfolded position and preventing the armrest 16 from rotating freely. When the locking block 21 slides out of the through hole, the armrest 16 loses its locking restriction and can now be folded by rotating around the rotating bar 15. When the armrest 16 needs to be unfolded, rotate the armrest 16 to a vertical position. During the rotation, the armrest 16 rotates around the rotating bar 15. After the armrest 16 reaches the vertical position, release the pressing handle 19. At this time, the spring 20, which was previously compressed and stored elastic potential energy, begins to rebound. The rebound of the spring 20 generates a downward thrust, pushing the pressing handle 19 down. The downward movement of the pressing handle 19 causes the locking block 21 to move down simultaneously, allowing the locking block 21 to slide back into the through hole inside the fixing sleeve 17. This allows the armrest 16 to be folded up when the user needs to get on or off the bed chair, reducing obstruction and facilitating the user's entry and exit, thus reducing the risk of bumps and injuries. When in use, the armrest 16 can be unfolded to provide support for the user, making it easier for them to get up, sit down, or place their arms while resting, increasing the convenience and comfort of use.

[0037] Working principle: When adjusting the angle of the backrest 2, the hydraulic rod 7 located below the backrest 2 on the base 4 is activated. The output end of the hydraulic rod 7 pushes the slider 8 to slide on the fixed frame 6, while the sliding block 9 slides in the slide groove 13. As the slider 8 moves, the connecting column 10 also moves, thereby causing the rotating plate 11 to rotate around the connecting column 10. The rotation of the rotating plate 11 will push the backrest 2 to rotate around its rotation connection point with the seat cushion 1 through the connecting block 12, thus adjusting the angle of the backrest 2. Similarly, when adjusting the angle of the leg support plate 3, the hydraulic rod 7 below the corresponding leg support plate 3 is activated. The hydraulic rod 7 retracts, pulling the slider 8 to slide in the opposite direction, thus adjusting the angle of the backrest 2. The rotating plate 11 rotates in the opposite direction, pulling the connecting block 12 on the lower surface of the leg support plate 3, causing the leg support plate 3 to move down around its rotating connection point with the seat cushion 1, thus adjusting the angle of the leg support plate 3. When the armrest 16 needs to be folded, press the pressing handle 19 upward to compress the spring 20, causing the locking block 21 to slide out of the through hole inside the fixing sleeve 17. At this time, the armrest 16 can rotate around the rotating bar 15 to fold. When the armrest 16 needs to be unfolded, rotate the armrest 16 to the vertical position, release the pressing handle 19, the spring 20 rebounds, pushing the pressing handle 19 down, causing the locking block 21 to slide back into the through hole inside the fixing sleeve 17, fixing the armrest 16 in the unfolded position.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
