Description

Technical Field

[0001] This utility model relates to the field of home bed technology, and in particular to a nursing home bed with multi-position intelligent adjustment. Background Technology

[0002] As living conditions continue to improve, people's demand for comfort and health care in home life is increasing. Against this backdrop, nursing home beds have emerged as a model of the integration of smart furniture and age-friendly design, allowing users to enjoy a comfortable experience while providing scientific support for family care.

[0003] Currently, most smart beds on the market have basic functions and do not meet people's requirements for a high-quality life. They cannot achieve smooth lifting and lowering of the entire bed or overall tilting adjustment, making it difficult for users to easily adjust to a comfortable height to get in and out of bed according to their own needs. For patients with special health needs (such as heart failure or insufficient blood flow to the brain), they cannot provide suitable body positions such as head-high or head-low or feet-high to improve their physical condition. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot achieve smooth overall lifting and lowering of the bed or overall forward and backward tilting, resulting in difficulties in getting in and out of bed and inability to provide a suitable forward and backward tilting position. Therefore, this invention proposes a nursing home bed with multi-position intelligent adjustment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-position intelligent adjustable nursing home bed, comprising: A bed frame, wherein a buttock board is fixedly installed at the top of the bed frame, a lumbar board is hinged to the front side of the buttock board, a lumbar support device is embedded in the center of the lumbar board, a back board is hinged to the front side of the lumbar board, a thigh board is hinged to the rear side of the buttock board, and a calf board is hinged to the rear side of the thigh board. The bottom of the bed frame is equipped with a lifting component, which can not only tilt the bed forward and backward, but also raise and lower the bed as a whole.

[0006] In one possible design, the lifting assembly includes a crossbeam fixedly mounted in the middle section of the bed frame. Four U-shaped frames are fixedly mounted in a rectangular shape on both sides of the left and right inner walls of the bed frame and on both sides of the crossbeam. The openings of the four U-shaped frames face inward, and rollers are rolled on the inner sides of each of the four U-shaped frames. The rollers in two symmetrical U-shaped frames are rotatably mounted on the same support frame. Connecting frames are hinged to both sides of the front and rear inner walls of the bed frame that are far apart from each other. Two connecting frames are respectively hinged to two support frames. Electric push rods are hinged to both sides of the crossbeam, and the output ends of the two electric push rods are respectively hinged to two connecting frames.

[0007] In one possible design, wheel frames are rotatably mounted on both sides of the bottom of the two support frames, and casters are fixedly mounted on the bottom of each wheel frame.

[0008] In one possible design, guardrails are fixedly installed on both sides of the bed frame near the front, and a headboard is fixedly installed on the front side of the bed frame.

[0009] In one possible design, a metal mesh frame is fixedly installed on the top inner side of the hip plate, back plate, thigh plate, and calf plate.

[0010] In one possible design, the lumbar support device includes a base frame fixed in the central notch of the lumbar plate, an adjustable upper frame positioned directly above the base frame, a linear guide rail fixedly mounted on the top of the base frame, a sliding beam slidably mounted on the top of the linear guide rail, and the base frame and the upper frame connected by two sets of hinged X-shaped arms. One end of the top of each X-shaped arm is hinged to the bottom of the upper frame, and the other end is slidably connected to a second slide rail corresponding to the bottom of the upper frame. One end of the bottom of each X-shaped arm is hinged to the top of the base frame, and the other end is hinged to the side wall of the sliding beam.

[0011] In one possible design, a lumbar support electric push rod is installed on one side of the base frame, and the other end of the lumbar support electric push rod is connected to one side of the sliding beam.

[0012] In this application, upon initial use, the entire nursing bed is first moved to the desired position using its casters. The position is then locked using the locks on the casters. Next, the entire nursing bed is powered on. At this point, the nursing bed is in its initial horizontal lying position, with the lumbar support retracted and a soft mattress fixed to it. The lifting assembly is also in its initial state (two electric actuators are retracted, and the bed frame is at its lowest position). When the user needs to lie on the mattress, two control buttons are pressed simultaneously to activate the two electric actuators. The output ends of the two electric actuators extend synchronously, pushing the connecting frame to rotate downwards on the bed frame. Simultaneously, the downward rotation of the connecting frame drives the two... One end of each support frame moves away from each other via rollers inside the U-shaped frame, while the other ends of the two support frames move towards each other on the ground via casters. As the two support frames move, the bed frame slowly rises. When it reaches a position convenient for getting in and out of bed, the electric push rod stops working. The user then gets into bed and lies on the mattress (at this time, the user can continue to raise or lower the bed frame according to the above operation to make it at a comfortable height). When it is necessary to get out of bed for storage, the two electric push rods are controlled to work in opposite directions according to the above operation, that is, the output ends of the two electric push rods retract synchronously, so that the ends of the two support frames with casters move away from each other on the ground. When adjusting the sitting posture, the user selects the "sitting posture" mode via remote control. The system automatically activates two electric actuators, whose output ends extend to raise the backrest and thigh support. Simultaneously, the lumbar support rises to a comfortable backrest angle. At the same time, the thigh support rises, and the side of the calf support not hinged to the thigh support lowers, forming a triangle. This allows the thighs to rise while the calves hang naturally, until a comfortable thigh and calf angle is achieved. When this ergonomic lumbar support is established, the lumbar spine... When the support device is activated, the electric actuator inside the lumbar support device starts working, pushing the sliding beam to slide on the linear guide rail. Since the sliding beam is hinged to one end of the bottom of the scissor (X-type) support arm, the other end of the bottom of the scissor (X-type) support arm is hinged to the top of the base frame, and one end of the top of the scissor (X-type) support arm is hinged to the bottom of the upper frame, and the other end is slidably connected to the second slide rail corresponding to the bottom of the upper frame, the sliding of the sliding beam will cause the scissor (X-type) support arm to deform, thereby pushing the upper frame to rise or fall, realizing the adjustment of the lumbar position height, accurately supporting the waist, and providing personalized lumbar support for users; If the user needs to adjust the bed's tilt angle to achieve different positions, they can also control the two electric actuators at the front and rear using the remote control buttons. To achieve a forward tilt (head higher than feet) position, activate the rear electric actuator, causing its output end to retract and pull the connecting frame forward and upward. As the connecting frame rotates and rises forward, it drives one end of the support frame to move towards the front of the bed via rollers within the U-shaped frame, while the other end of the support frame moves towards the rear of the bed via casters on the ground. This causes the front of the bed frame to rise and the rear to fall, creating a head-high-feet-low posture. This position reduces venous return to the heart, alleviates cardiac preload, and is significantly helpful for patients with heart failure. Furthermore, this sitting posture makes watching movies / TV shows, dining, and working more comfortable. Comfortable and easier, once the desired forward tilt angle is reached, the operation of the electric push rod on the rear side of the bed is stopped, and the bed remains in this position. To achieve a backward tilt (head down, feet up) position, the output end of the electric push rod on the front side retracts, which also drives the connecting frame hinged to it to rotate upward. The upward rotation of the connecting frame causes one end of the support frame to move towards the rear of the bed through rollers in the U-shaped frame, while the other end of the support frame moves towards the front of the bed on the ground through casters. Thus, the front end of the bed frame lowers and the rear end rises, forming a head-down, feet-up posture. This position can reduce blood flow to the lower limbs and increase cerebral perfusion, which is significantly beneficial for patients with insufficient cerebral blood flow. Once the desired backward tilt angle is reached, the operation of the electric push rod on the front side of the bed is stopped, and the bed remains in this position.

[0013] This utility model has the following beneficial effects: This invention utilizes a lifting component to achieve stable overall bed lifting, allowing users to easily adjust to a comfortable height for getting in and out of bed. It also enables overall forward and backward tilting adjustment, creating either a head-high or head-low-foot-high position to meet the needs of users with different health conditions. For example, it can reduce the cardiac load on patients with heart failure and improve the condition of patients with insufficient cerebral blood flow, thus comprehensively enhancing the practicality and comfort of the nursing bed.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In one embodiment Reference Figure 1-4 A type of home bed, comprising: The bed frame consists of components such as the bed frame 1, hip board 2, lumbar support board 3, lumbar support device 4, backrest 5, thigh board 6, calf board 7, lifting assembly, guardrail 14, and headboard 15. These components work together to achieve intelligent adjustment of the bed in various positions, meeting the needs of different users. The bed frame 1, as the supporting frame of the entire nursing home bed, is made of high-strength steel, which has good stability and load-bearing capacity. Its overall rectangular structure is designed according to common bed specifications, which can meet the needs of general users. Guardrail 14 is fixedly installed on both sides near the front of the bed frame 1. The guardrail 14 is made of stainless steel, which can effectively prevent users from slipping off the bed during use and ensure safety. The headboard 15 is fixedly installed on the front of the bed frame 1. The headboard 15 is made of wood and can be fitted with a soft cushion.

[0018] The buttock board 2 is fixedly installed on the top of the bed frame 1 to provide support for the user's buttocks. A metal mesh frame is fixedly installed on the inner top of the buttock board 2. The metal mesh frame is woven from stainless steel wire. The lumbar board 3 is hinged to the front of the buttock board 2 and can rotate around the hinge point at a certain angle. A lumbar support device 4 is embedded in the center of the lumbar board 3.

[0019] A back panel 5 is hinged to the front of the waist panel 3. The back panel 5 supports the user's back. A metal mesh frame is also fixedly installed on the top inner side of the back panel 5. A thigh panel 6 is hinged to the rear of the hip panel 2. The thigh panel 6 supports the user's thighs. A calf panel 7 is hinged to the rear of the thigh panel 6. The calf panel 7 supports the user's calves. A metal mesh frame is also fixedly installed on the top inner side of both the thigh panel 6 and the calf panel 7 to ensure comfort during use.

[0020] The lifting mechanism is located at the bottom of the bed frame 1. It allows the bed to tilt forward and backward. When tilted forward with the head higher than the feet, it reduces venous return to the heart, alleviating cardiac preload and significantly benefiting patients with heart failure. This sitting position also makes watching movies, dining, and working more comfortable and relaxed. When tilted backward with the head lower than the feet, it reduces blood flow to the lower limbs and increases cerebral perfusion, significantly benefiting patients with insufficient cerebral blood supply. The lifting mechanism also allows for easy getting in and out of bed. The lifting mechanism includes a crossbeam 101 fixed in the middle of the bed frame 1. The crossbeam 101 is made of high-strength steel and serves as a connector and support. Four U-shaped frames 8 are rectangularly fixed on both sides of the inner left and right walls of the bed frame 1, located on either side of the crossbeam 101. The openings of the four U-shaped frames 8 face inward and are evenly distributed. On both sides of the inner wall of the bed frame 1, rollers are rolled on the inner sides of the four U-shaped frames 8. The rollers are made of wear-resistant rubber, which can reduce the friction between the rollers and the U-shaped frames 8 and make the movement smoother. The rollers in the two symmetrical U-shaped frames 8 are rotated by the same support frame 9. The support frame 9 is welded from steel and has sufficient strength and stability. Connecting frames 10 are hinged on both sides of the front and rear inner walls of the bed frame 1. The two connecting frames 10 are respectively hinged to the two support frames 9 to form a movable connection structure. Electric push rods 11 are hinged on both sides of the crossbeam 101. The output ends of the two electric push rods 11 are respectively hinged to the two connecting frames 10. Through the extension and retraction of the electric push rods 11, the connecting frames 10 and the support frames 9 are driven to move, thereby realizing the lifting and tilting adjustment of the bed.

[0021] Both support frames 9 are rotatably equipped with wheel frames 12 on both sides of their bottom. The wheel frames 12 are made of steel and are connected to the support frames 9 via axles. Each wheel frame 12 is fixedly equipped with a caster 13 at its bottom. The caster 13 is a universal wheel with brakes to facilitate the movement and fixation of the bed.

[0022] This application can be used in the field of nursing home bed technology with multi-position intelligent adjustment, and can also be used in other fields applicable to this application.

[0023] In another embodiment Reference Figure 4-5A multi-position intelligent adjustable nursing home bed is described, applying the field of multi-position intelligent adjustable nursing home bed technology. The lumbar support device 4 includes a base frame 17 fixed within a central notch in the lumbar support plate 3. A height-adjustable upper frame 16 is positioned directly above the base frame 17. A linear guide rail 18 is fixedly mounted on the top of the base frame 17, and a matching sliding beam 19 is slidably mounted on the top of the linear guide rail 18. The base frame 17 and the upper frame 16 are connected by two sets of hinged X-shaped support arms 21. One end of the top of each X-shaped support arm 21 is hinged to the bottom of the upper frame 16, and the other end is slidably connected to a corresponding second slide rail 22 at the bottom of the upper frame 16. One end of the arm 21 is hinged to the top of the base frame 17 and the other end is hinged to the side wall of the sliding beam 19. A lumbar support electric push rod 20 is installed on one side of the base frame 17, and the other end of the lumbar support electric push rod 20 is connected to one side of the sliding beam 19. When it is necessary to adjust the height of the lumbar support, the lumbar support electric push rod 20 is started by wireless remote control. The lumbar support electric push rod 20 pushes the sliding beam 19 to slide on the linear guide rail 18. The sliding of the sliding beam 19 causes the scissor X-shaped support arm to deform. The deformation of the scissor X-shaped support arm pushes the lumbar support frame to rise or fall, thereby realizing the adjustment of the lumbar position protrusion height, lifting the waist and providing personalized lumbar support for the user.

[0024] However, as is well known to those skilled in the art, the working principle and wiring method of the electric actuator 11 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0025] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
