Technical Field

[0001] This utility model relates to the field of nursing beds, and more particularly to a nursing bed with a head support. Background Technology

[0002] A nursing bed is a bed specifically designed to meet nursing needs, primarily used in medical and nursing facilities as well as in home care settings. Its biggest difference from a regular bed lies in its multiple functions, facilitating care for patients with limited mobility or those who are bedridden for extended periods, while simultaneously improving their comfort and quality of life.

[0003] Traditional nursing beds have many shortcomings in assisting users to transition from a lying to a sitting position. Many nursing beds fail to accurately simulate the natural process of sitting up, often with the headboard and backrest rising simultaneously, or the backrest rising before the headboard. This results in the user's head suddenly being unsupported when sitting up, putting significant pressure on the neck, causing discomfort, and potentially even neck injury, severely impacting the user's experience and comfort. Therefore, a nursing bed with a headrest is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a nursing bed with a head support, which aims to improve the problem in the prior art that causes the user's head to suddenly suspend in the air when sitting up, resulting in greater pressure on the neck and discomfort.

Detailed Implementation

[0029] 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.

[0030] Reference Figures 1-3 This utility model provides an embodiment of a nursing bed with a headrest, comprising a bed frame 1 and a base frame 2. The bed frame 1 and base frame 2 are the basic components of the entire nursing bed, providing installation space for other subsequent components. A hip support plate 3 is fixedly connected to the middle of the bed frame 1. The hip support plate 3 is an important support part of the entire nursing bed, supporting the patient's hips. A back support plate 4 is rotatably connected to one side of the hip support plate 3. The back support plate 4 rotates under the drive of a first lifting component, thereby better conforming to the patient's back and providing support. A thigh support plate 5 is rotatably connected to the other side of the hip support plate 3. The thigh support plate 5 rotates under the drive of a second lifting component, thereby adjusting the placement angle of the thighs according to the patient's needs, avoiding... To address the numbness caused by prolonged leg positioning, a head support plate 6 is rotatably connected to the side of the back support plate 4 away from the hip support plate 3. Driven by a first lifting assembly, the head support plate 6 rotates, allowing for angle adjustment and consistently providing comfortable and stable support for the user's head. A calf support plate 7 is rotatably connected to the side of the thigh support plate 5 away from the hip support plate 3. A second lifting assembly, via a fourth link 23, drives the calf support plate 7 to rotate around its connection point with the thigh support plate 5, providing flexible support for different leg positions and meeting diverse rest needs. A first lifting assembly is located at the bottom of the hip support plate 3, controlling the lifting angles of the back support plate 4 and head support plate 6. A second lifting assembly is located at the bottom of the bed frame 1, controlling the angles of the thigh support plate 5 and calf support plate 7. A bed surface lifting assembly is also located at the bottom of the bed frame 1, adjusting the overall height of the bed surface.

[0031] Reference Figures 2-4 The first lifting component includes two mounting brackets 8, which are fixedly connected to the bottom of the hip support plate 3. The mounting brackets 8 provide stable support points for the installation of the first and second lifting components. A first electric push rod 10 is rotatably connected to the middle of the left mounting bracket 8. A special-shaped connecting rod 12 is rotatably connected to the output end of the first electric push rod 10. A first connecting rod 13 is rotatably connected to the middle of the special-shaped connecting rod 12. The end of the first connecting rod 13 away from the special-shaped connecting rod 12 is rotatably connected to the bottom of the head support plate 6. When the first electric push rod 10 is powered on, it will drive the special-shaped connecting rod 12 at its output end to rotate. When the special-shaped connecting rod 12 rotates, it will drive the special-shaped connecting rod 12 to rotate, thereby adjusting the angle of the head support plate 6. When the angle of the head support plate 6 is adjusted, the special-shaped connecting rod 12 will push the back support plate 4 to rotate, thereby adjusting the angle of the back support plate 4.

[0032] Reference Figure 2 and Figure 3 The second lifting assembly includes a second electric push rod 11 and a fourth connecting rod 23. The second electric push rod 11 is rotatably connected to the middle of the right mounting bracket 8. The second electric push rod 11 is driven by an internal hydraulic cylinder by a motor to achieve extension and retraction of the push rod. The output end of the second electric push rod 11 is rotatably connected to the bottom of the thigh support plate 5. When the second electric push rod 11 extends, it pushes the thigh support plate 5 to rotate upward around the connection point with the hip support plate 3; when it shortens, the thigh support plate 5 falls back. One end of the fourth connecting rod 23 is fixedly and rotatably connected to the bottom of the calf support plate 7, and the other end of the fourth connecting rod 23 is rotatably connected to the inner wall of the bed frame 1. When the thigh support plate 5 rotates under the action of the second electric push rod 11, the force is transmitted to the calf support plate 7 through the fourth connecting rod 23, so that the calf support plate 7 rotates around the connection point with the thigh support plate 5, thereby realizing the adjustment of the overall posture of the legs.

[0033] Reference Figure 2 and Figure 3 The bed lifting assembly includes two support rods 14 and a third electric push rod 17. The support rods 14 are rotatably connected to the bottom of the bed frame 1, and provide the mounting base for other components in the bed lifting assembly. Two connecting blocks 15 are fixedly connected to the outer wall of the left support rod 14, and one connecting block 15 is fixedly connected to the outer wall of the right support rod 14. A second connecting rod 16 is rotatably connected between the two connecting blocks 15. When one support rod 14 rotates under the action of the third electric push rod 17, it drives the other support rod 14 to rotate synchronously through the connecting block 15 and the second connecting rod 16. Two second connecting rods 18 are fixedly connected to the outer wall of the support rod 14. The second connecting rods 18 transmit the movement of the support rod 14 to the third connecting rod 19. The second connecting rods 18 are away from the support rod 14. One end of the support rod 14 is rotatably connected to a third link 19. A rotating shaft 20 is fixedly connected between the ends of two adjacent third links 19 that are away from the second link 18. The third link 19 and the rotating shaft 20 further transmit and convert the motion, ultimately achieving a smooth lifting and lowering of the bed surface. The third electric push rod 17 is fixedly connected to the bottom of the hip support plate 3. The third electric push rod 17 provides power for the entire bed surface lifting assembly. When the third electric push rod 17 extends, it pushes the support rod 14 to rotate around its rotation point with the bed frame 1. Through the connecting block 15 and the second connecting rod 16, it drives the right support rod 14 to rotate synchronously. Then, through the second link 18 and the third link 19, the rotation of the support rod 14 is converted into the upward motion of the bed surface. When the third electric push rod 17 shortens, the bed surface lowers.

[0034] Reference Figures 2-4The end of the irregularly shaped connecting rod 12 away from the first connecting rod 13 is rotatably connected to the bottom of the back support plate 4, so that the irregularly shaped connecting rod 12 can drive the head support plate 6 to move under the drive of the first electric push rod 10. After the head support plate 6 has finished moving, it will drive the back support plate 4 to move. The first connecting rod 9 is fixedly connected between the two mounting brackets 8. The first connecting rod 9 enhances the structural stability between the two mounting brackets 8, making the first lifting assembly and the second lifting assembly more robust and reliable during operation.

[0035] Reference Figures 1-3 The base frame 2 has four fixed casters 22 at the bottom corners. The casters 22 improve the mobility of the nursing bed, making it easy to adjust the device to other positions in the ward. The inner wall of the bed frame 1 has two handrails 21 fixedly connected. The handrails 21 provide reliable gripping support points for users, making it convenient for users to use their strength when sitting up, lying down or adjusting their posture.

[0036] Reference Figure 3 The output end of the third electric push rod 17 is rotatably connected to the middle of the edge connecting block 15 on the outer wall of the left support rod 14. Since the two opposite connecting blocks 15 are rotatably connected by the second connecting rod 16, when the third electric push rod 17 is driven, it will drive the connecting block 15 on the edge of the support rod 14 to rotate, thereby driving the support rod 14 to rotate. The rotation of the support rod 14 is transmitted through the second connecting rod 16 between the two opposite connecting blocks 15, further driving the other support rod 14 to rotate. The two opposite connecting blocks 15 move in the same direction, ensuring that the power of the third electric push rod 17 is evenly transmitted to the two support rods 14. Because the two opposite connecting blocks 15 move in the same direction, through the synergistic effect of the connecting blocks 15, the second connecting rod 16 and other structures, the two support rods 14 can rotate synchronously and smoothly.

[0037] Reference Figure 2 The rotating shaft 20 is rotatably connected to the inner wall of the base frame 2, providing a crucial stable support point and rotating shaft for the movement of the entire bed lifting assembly.

[0038] Working principle: When the user needs to adjust to a sitting position, the first electric push rod 10 is powered on and starts. After starting, the first electric push rod 10 will extend, thereby pushing the connected irregular connecting rod 12 to rotate. At the same time, it will rotate itself. When the irregular connecting rod 12 rotates, it will drive the first connecting rod 13 in its middle to rotate. The rotation of the first connecting rod 13 will drive the head support plate 6 to rotate, thereby adjusting the angle of the head support plate 6. When the angle of the head support plate 6 is adjusted to a certain angle, the back support plate 4 will rotate under the influence of the shape of the irregular connecting rod 12, thereby adjusting the angle of the back support plate 4, so that the head rises first and then the back rises, thus completing the sitting action.

[0039] When the user needs to adjust the leg support posture, the second electric push rod 11 is energized and extended, thereby driving the thigh support plate 5 on its output end to rotate. When the thigh support plate 5 rotates, it will drive the lower leg support plate 7 to rotate. Since the outer wall of the lower leg support plate 7 is equipped with a fourth connecting rod 23, and one end of the fourth connecting rod 23 is fixed to the inner wall of the bed frame 1, when the thigh support plate 5 rotates, it will drive the lower leg support plate 7 to rotate upward around the rotation point of the thigh support plate 5, thereby adjusting the leg posture from a straight state to a bent state.

[0040] When the user needs to adjust the height of the bed surface, the third electric push rod 17 is energized and extended, thereby pushing the connecting block 15 on the outer edge of the support rod 14 at its output end to rotate. When the connecting block 15 rotates, it drives the support rod 14 to rotate, and through the connection between the two connecting blocks 15 and the second connecting rod 16, it drives the other support rod 14 to rotate. The rotation of the support rod 14 drives the second connecting rod 18 on its outer wall to rotate, and drives the third connecting rod 19 to rotate around the center of the pivot 20, thereby raising the entire bed surface.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
