Description

Technical Field

[0001] The invention relates to furniture, in particular to a multi-freedom adjustable sleeping-aiding bed. Background Art

[0002] Traditional bedding lacks the function of automatic body position adjustment, so sleepers need to turn over and change the pressure points on their own. However, maintaining a single posture for a long time in deep sleep can easily lead to continuous pressure on local tissues. This biomechanical feature may cause microcirculatory disorders, clinically manifested as pressure pain, limb numbness, and peripheral edema. Especially for patients with motor dysfunction, obese people, and those who are bedridden for a long time, this type of static pressure distribution pattern will significantly increase the incidence of pressure sores (stage II and above), aspiration pneumonia, and deep vein thrombosis.

[0003] The existing solution to avoid prolonged pressure on the body is to use a body position conversion bed, which is mostly a medical device. It completes the body position conversion from supine to left to right in a certain period. The body position conversion method is mostly to divide the bed board into two left and right parts according to the length of the human body, and the lateral position of the body is changed by flipping the left or right bed board. However, this method will push the sleeping body, destroy the deep sleeping state, and thus affect the sleep quality.

[0004] At the same time, the existing functional beds or health-care beds can generally only realize the supine→left→right cyclic body position conversion when replacing and converting, and cannot realize the adjustment of a larger angle, so there is room for further optimization. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a multi-degree-of-freedom adjustable sleep-aiding bed to solve the technical problems raised by the background technology.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0007] A multi-degree-of-freedom adjustable sleep-aiding bed comprises a bed frame and a bed body, wherein the bed body is mounted on the bed frame.

[0008] The bed support includes a rotating mechanism and / or a height adjustment mechanism, wherein the height adjustment mechanism can realize the height adjustment of the head and / or foot of the bed; the rotating mechanism can realize the 0-360° rotation of the bed with the direction of the head and feet of the human body as the axis;

[0009] The bed body comprises a bed board and a human body protection and fixing mechanism, wherein the human body protection and fixing mechanism sets a human body protection and fixing mode according to a rotation angle of the rotating mechanism;

[0010] The central controller monitors the angle of the bed through the sensor module and controls the rotating mechanism, the height adjustment mechanism and the human body protection fixing mechanism.

[0011] Furthermore, during the rotation of the bed board by 0-90°, the human body protection and fixing mechanism includes blocks located on both sides of the bed board, and the blocks on the downward moving side gradually move toward the body and fit the body during the tilting of the bed board; during the rotation of the bed board by more than 90°, the human body protection and fixing mechanism includes blocks located on both sides of the bed board and a body fixing device, and the body fixing device is connected to both sides of the bed board or to the blocks, and the body fixing device fixes the body by tightening or filling.

[0012] Furthermore, the bed support comprises two height-adjustable support frames arranged at the head and foot of the bed, and rotating shafts are respectively arranged on the two support frames, and the two ends of the bed are connected to the rotating shafts.

[0013] Furthermore, the human body protection and fixing mechanism is a movable block and a body fixing device installed on both sides of the bed board, the body fixing device is a soft curtain and a soft curtain tightening device arranged in one of the blocks, the soft curtain is connected to the soft curtain tightening device, and a soft curtain end fixing device is provided in the block on the other side, and the soft curtain tightening device is connected to the central controller.

[0014] Furthermore, the human body protection and fixing mechanism is a movable stopper and a body fixing device installed on both sides of the bed board, and the two sides of the body fixing device are respectively connected to the two sides of the bed board; the body fixing device includes two slide rails respectively located at the head and foot of the bed, and the two ends of the slide rails are respectively connected to the two sides of the bed board, and a bed curtain that can slide along the slide rails is provided between the two slide rails, and the bed curtain includes a plurality of support bars arranged in parallel, and two adjacent support bars are connected by a flexible connector.

[0015] Furthermore, the human body protection fixing mechanism also includes a traction mechanism controlled by a central controller, and a traction end of the traction mechanism is located in the slide rail and connected to the end of the bed curtain.

[0016] Furthermore, the human body protection and fixing mechanism is a bed board, which is formed by a plurality of hinged board surfaces, and the hinged board surfaces can only be folded upwards of the bed board. A soft curtain and a soft curtain tightening device are provided on the board surface on one side of the bed board, and the soft curtain is connected to the soft curtain tightening device. A soft curtain end fixing device is provided on the board surface on the other side of the bed board, and the soft curtain tightening device is connected to a central controller. In this way, during the tilting process of the bed board, the board surface that is not compressed when the soft curtains are pulled against each other will bend upwards to perform the function of human body protection and fixing.

[0017] Furthermore, an air curtain is provided on the surface of the soft curtain close to the human body, and an air pump is connected to the air curtain, and the air pump is connected to the central controller.

[0018] Furthermore, the inner side of the support bar is covered with an elastic cushion layer.

[0019] Furthermore, the body fixing device is an inflatable airbag.

[0020] The beneficial effects of the present invention are:

[0021] The multi-degree-of-freedom adjustable sleep-aid bed proposed by the present invention is based on a bed frame and a bed. Through the rotating mechanism and the height adjustment mechanism on the bed frame, the height adjustment mechanism can respectively adjust the height of the head and foot of the entire bed; the rotating mechanism can realize 0-360° rotation of the bed with the direction of the head and feet of the human body as the axis, making it obviously different from the existing nursing bed (using the multi-section design of the bed to realize the split adjustment of the head and foot of the bed and the adjustment of the body from supine to side lying). When in use, the user sets the movement mode and movement cycle of the bed through the central controller according to the use requirements, and then falls asleep in the same way as an ordinary bed. When the user lies on the bed to rest or falls asleep, the central controller will realize the lifting and lowering of the head or foot of the bed according to the user's settings, and realize the overall rotation of the bed board. For example, setting the head of the bed to be raised within a certain period can improve the breathing work, and raising the foot of the bed can improve the venous return rate. The overall rotation of the bed board can cause the center of gravity of the human body to shift in the same posture. The shift of the center of gravity of the body can effectively avoid the blood circulation problems that are easily caused by the body maintaining a single posture for a long time in a deep sleep state.

[0022] The human body protection and fixing mechanism sets the protection and fixing mode of the human body according to the rotation angle of the rotating mechanism, that is, the setting of the human body protection and fixing mechanism can enable the rotating mechanism to escort during the 0-360° rotation process. Specifically, if the human body protection and fixing mechanism is not enabled, in order to prevent the human body from rolling over, the upper limit of the inclination of the bed board driven by the rotating mechanism is 45°. If the enabled human body protection and fixing mechanism is the blocks set on both sides of the bed board, then the upper limit of the inclination of the bed board driven by the rotating device is 90°. After rotating 90°, the body will achieve a side-lying sleeping position. A regular periodic forward or reverse rotation can achieve a cyclic conversion between supine → left-side → supine → right-side lying. Because the bed board rotates slowly as a whole, it is gentler than the existing push-body-type turning over, so it will not destroy the sleeping state or deep sleeping state, thereby improving the sleep quality. If the activated human body protection fixing mechanism is the blocks set on both sides of the bed board and the protective curtains surrounding the body, the rotating device will drive the bed board to rotate 360°. After the rotating device rotates more than 90°, the protective curtains will tighten the body and fix it on the bed board. At this time, the body can form the effect of sleeping on the bed. At the same time, the adjustment of this shape can be more friendly to people who are bedridden and have difficulty in moving, and can achieve more resting positions and convenient urination.

[0023] During the 0-90° rotation of the bed board, the blocks arranged on both sides of the bed board, and the block 5 on the side moving downward during the tilting of the bed board will move toward the body and gradually move to fit the body, which can prevent the human body from slipping, and when the bed board is tilted to the side-lying position, the block will become the bed board that supports the body.

[0024] The bed support adopts two height-adjustable support frames installed at the head and foot of the bed. The height of the head and foot of the bed is convenient to adjust at this position and will not occupy the space under the bed. Rotating shafts are respectively arranged on the two support frames, and the two ends of the bed are connected to the rotating shafts. In this way, the rotating mechanism directly drives the rotating shafts to realize the rotation of the bed. At the same time, the above-mentioned components can be covered with the decorations of the head and foot of the bed, which will not affect the overall aesthetics of the present invention.

[0025] The body fixing device includes a soft curtain, a soft curtain tightening device and a soft curtain end fixing device. The soft curtain tightening device tightens the soft curtain. The tightened soft curtain cooperates with the bed board and the blocks on both sides of the bed board to protect and fix the human body to prevent the human body from moving relative to the bed body and affecting sleep. The device can adapt to people of different fat and thin sizes.

[0026] The body fixing device includes a slide rail at the head and foot of the bed and a bed curtain between the two slide rails that can slide along the slide rails. The structure has good strength, and a filling air bag is arranged inside the bed curtain. It can adapt to different fat and thin bodies with the block on both sides of the bed board. After the bed curtain is connected to the traction mechanism, it is more convenient to open and close the bed curtain.

[0027] The human body protection and fixing mechanism is composed of a bed board formed by several hinged board surfaces, a soft curtain, a soft curtain tightening device and a soft curtain end fixing device. In this way, when the bed board is tilted, the unpressed board surface will bend upward under the mutual traction state of the soft curtains to play the function of human body protection and fixing, and can adapt to people of different fat and thin bodies.

[0028] An air curtain is arranged inside the soft curtain to make the human body more comfortable and have a better fixation effect on the human body.

[0029] The body fixing device is an air bag with a simple structure.

[0030] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description and claims. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0046] Embodiment 1

[0047] like Figure 1-3The multi-degree-of-freedom adjustable sleep-aid bed shown in the figure is composed of a bed body and a central controller installed on a bed body bracket. The bed body bracket includes a support plate 1 placed on the floor of the room, and two support frames 2 are fixed at both ends of the support plate 1, which are respectively located at the head and the foot of the bed. For the convenience of viewing the figure, in this embodiment, the head of the bed is at the rear and the foot of the bed is at the front. Bearing mounting holes are respectively provided at the upper ends of the two support frames 2. After the bearings are installed in the bearing mounting holes, a rotating shaft 3 is connected. One end of one of the rotating shafts 3 extends out of the support frame 2 and is connected to a rotating mechanism. The rotating mechanism is fixed to the support frame 2. The rotating mechanism is a stepping motor. The bed body is connected between the two rotating shafts 3, and an angle sensor is connected to the rotating shaft 3; the bed body includes a bed board 4, and a human body protection fixing mechanism is provided on the bed board 4. The human body protection fixing mechanism in this example is respectively provided The block 5 is arranged on the left and right sides of the bed board. In order to realize that the block 5 on the side moving downward will move toward the body during the tilting process of the bed board, and gradually move to fit the body, the block 5 needs to be designed to be movable. There are many ways to realize the block moving from the left and right sides of the bed board to the middle, such as a slider 6 is arranged under the block 5, and the left and right sides of the bed board 4 are respectively provided with guide rails 7 extending in the left and right directions. The slider 6 on the block 5 on the left side of the bed board 4 is slidably arranged in the guide rail 7 on the left side of the bed board 4, and the slider on the block 5 on the right side of the bed board 4 is slidably arranged in the guide rail 7 on the right side of the bed board 4. The slider 6 on the left side of the bed board 4 and the slider 6 on the right side of the bed board 4 are respectively connected with a linear motion mechanism 8, which is arranged in the left and right directions. The linear motion mechanism 8 is an electric telescopic rod, a hydraulic cylinder or a pneumatic cylinder fixed at the bottom of the bed board 4. Pressure sensors are respectively arranged on the opposite sides of the two block 5, and the angle sensor and the pressure sensor are connected to the input end of the central controller, and the output end of the central controller is connected to the remote control, the stepping motor and the linear motion mechanism 8.

[0048] At the same time, in order to avoid grooving on the mattress, slide grooves can also be set on the head of the bed and the bed board, and the two ends of the stopper are installed in the slide groove, and the movement of the stopper is realized by a translation rack motor.

[0049] When the sleep-aid bed is in use, the user sets the movement mode and movement cycle of the bed through the central controller according to the use requirements, and the angle adjustment range is -90° to 90°, and then the user can fall asleep in the same way as an ordinary bed. When the user is lying on the bed to rest or fall asleep, the central controller will control the rotating mechanism according to the setting to start the bed body to rotate slowly (the degree of slowness shall be based on the human body's insensibility) within the range of -90 degrees to 90 degrees, where the bed body is horizontal at 0°, and the angle sensor detects the rotation angle of the rotating shaft 3 in real time. When it is detected that the rotation angle of the rotating shaft 3 is between -30 degrees and 30 degrees, the stopper 5 is located on both sides of the bed board and does not move. When it is detected that the rotation angle of the rotating shaft 3 is greater than 30 degrees, the central controller controls the linear motion mechanism 8 to start the stopper on the right side. The block 5 moves to the left. When the value detected by the pressure sensor on the right block 5 reaches the set value, the central controller controls the linear motion mechanism 8 to stop moving. On the contrary, when it is detected that the rotation angle of the rotating shaft 3 is less than -30°, the central controller controls the linear motion mechanism 8 to move to the right with the block 5 on the left. When the value detected by the pressure sensor on the left block 5 reaches the set value, the central controller controls the linear motion mechanism 8 on the left to stop moving. The sleep-aiding bed can protect and fix the human body through the blocks 5 on both sides of the bed body to prevent the human body from sliding left and right along the bed board 4 to affect sleep. Moreover, when the bed board is tilted to the side-lying position, the block will become the bed board that supports the body, which can realize the cyclic conversion of the human body between supine → left-side lying → supine → right-side lying ( Figure 3 This is a front view of an embodiment of the present invention in which a bed board moves to different states, which can avoid continuous pressure on local tissues caused by maintaining a single sleeping posture for a long time.

[0050] Embodiment 2

[0051] like Figure 4-9The multi-degree-of-freedom adjustable sleep-aid bed shown in the figure is composed of a bed body and a central controller installed on a bed body bracket. The bed body bracket includes a support plate 1 placed on the floor of the room, and two support frames 2 are fixed at both ends of the support plate 1, which are respectively located at the head and the foot of the bed. For the convenience of viewing the figure, in this embodiment, the head of the bed is at the rear and the foot of the bed is at the front. Bearing mounting holes are respectively provided at the upper ends of the two support frames 2. After the bearings are installed in the bearing mounting holes, a rotating shaft 3 is connected. One end of one of the rotating shafts 3 extends out of the support frame 2 and is connected to a rotating mechanism. The rotating mechanism is fixed to the support frame 2. The rotating mechanism is a stepper motor. The stepper motor drives the rotating shaft to rotate within the range of 0-360°. The bed body is connected between the two rotating shafts 3, and an angle sensor is connected to the rotating shaft 3; the bed body includes a bed board 4, and the left and right sides of the bed board 4 are respectively provided with human body protection fixing mechanisms. In this example The human body protection fixing mechanism is a block 5 respectively set on the left and right sides of the bed board. In order to realize that the block 5 on the side moving downward will move toward the body during the tilting process of the bed board and gradually move to fit the body, the block 5 needs to be designed to be movable. There are many ways to realize the block moving from the left and right sides of the bed board to the middle. For example, a slider 6 is provided under the block 5, and a guide rail 7 extending along the left and right directions is provided on the left and right sides of the bed board 4, respectively. The slider 6 on the block 5 on the left side of the bed board 4 is slidably set in the guide rail 7 on the left side of the bed board 4, and the slider on the block 5 on the right side of the bed board 4 is slidably set in the guide rail 7 on the right side of the bed board 4. The slider 6 on the left side of the bed board 4 and the slider 6 on the right side of the bed board 4 are respectively connected with a linear motion mechanism 8, which is set in the left and right directions. The linear motion mechanism 8 is an electric telescopic rod, a hydraulic cylinder or a pneumatic cylinder fixed at the bottom of the bed board 4. Pressure sensors are respectively provided on the opposite sides of the two blocks 5, and the angle sensor and the pressure sensor are connected to the input end of the central controller, and the output end of the central controller is connected to the remote control, the stepping motor and the linear motion mechanism 8.

[0052] At the same time, in order to avoid grooving on the mattress, slide grooves can also be set on the head of the bed and the bed board, and the two ends of the stopper are installed in the slide groove, and the movement of the stopper is realized by a translation rack motor.

[0053] The human body protection fixing mechanism also includes a body fixing device, which sets the two blocks 5 as a hollow structure with an open top. The body fixing device is a soft curtain 10 and a soft curtain tightening device arranged in the block 5 on the left side. The soft curtain 10 is connected to the soft curtain tightening device. A quick-connect buckle is provided at the end of the soft curtain 10. A soft curtain end fixing device is provided in the block 5 on the right side. The soft curtain end fixing device is a card slot matching the quick-connect buckle. The soft curtain tightening device is connected to the central controller. In this example, the soft curtain tightening device can select a common rolling door motor or a tubular motor, and can also use a telescopic mechanism 9 arranged at intervals in the block 5 along the front and rear directions, such as Figure 5As shown, the telescopic mechanism 9 is vertically arranged, and the telescopic mechanism 9 can select an electric telescopic rod, a hydraulic cylinder or a pneumatic cylinder. One end of the soft curtain 10 is connected to the end of the telescopic mechanism, and the other side is connected to the card slot through a quick-connect buckle. In order to facilitate ventilation when sleeping on your stomach, a ventilation hole 11 is provided on the soft curtain 10 corresponding to the face, and an air curtain is provided on the surface of the soft curtain 10 close to the human body. An air pump is connected to the air curtain, and the air pump is connected to the central controller. At the same time, the air curtain can be customized according to the body shape of the user, thereby better realizing the positioning of the human body.

[0054] When the sleeping-aid bed is in use, the human body needs to lie flat on the bed first, and the user sets the movement mode and movement cycle of the bed through the central controller according to the use requirements. If the angle adjustment range is set to 0° to ±360°, the body fixing device needs to be bound, that is, the soft curtain 10 is pulled out and buckled, but at this time the soft curtain 10 is not tightened, the air curtain is not inflated, and there is no restraint on the human body. When the user is lying in bed to rest or fall asleep, the central controller will control the rotating mechanism according to the setting to start the bed body to rotate slowly (the degree of slowness shall be based on the human body being unable to feel) within the range of -90 degrees to 90 degrees, where the bed body is horizontal at 0°, and the angle sensor detects the rotation angle of the rotating shaft 3 in real time. When it is detected that the rotation angle of the rotating shaft 3 is between -30 degrees and 30 degrees, the block 5 is located on both sides of the bed board and does not move. When it is detected that the rotation angle of the rotating shaft 3 is greater than 30 degrees, the central controller controls The linear motion mechanism 8 moves leftward with the block 5 on the right side, and when the value detected by the pressure sensor on the block 5 on the right side reaches the set value, the central controller controls the linear motion mechanism 8 to stop moving. Conversely, when it is detected that the rotation angle of the rotating shaft 3 is less than -30°, the central controller controls the linear motion mechanism 8 to move rightward with the block 5 on the left side, and when the value detected by the pressure sensor on the block 5 on the left side reaches the set value, the central controller controls the linear motion mechanism 8 on the left side to stop moving. The sleep-aiding bed can protect and fix the human body through the blocks 5 on both sides of the bed body to prevent the human body from sliding left and right along the bed board 4 to affect sleep, and when the bed board is tilted to the side-lying position, the blocks will become the bed board that supports the body, so that the human body can realize the cyclic conversion between supine → left-side lying → supine → right-side lying, and avoid maintaining a single sleeping posture for a long time and causing continuous pressure on local tissues. When it is detected that the rotation angle of the rotating shaft 3 is greater than +90° or less than -90°, the central controller controls the linear motion mechanism 8 to move the block 5 on the left and right sides to the middle. When the value detected by the pressure sensor on the block 5 reaches the set value, the central controller controls the linear motion mechanism 8 to stop moving. At the same time, the soft curtain tightening device and the air pump are started to cover the human body to ensure the stability of the human body when flipping. Figure 6-9 This is a front view of the bed board moving to different states in embodiment 2 of the present invention.

[0055] Embodiment 3

[0056] like Figure 10-12The multi-degree-of-freedom adjustable sleeping bed shown is composed of a bed body and a central controller installed on a bed body support. The bed body support includes a support plate 1 placed on the floor of the room, and two support frames 2 are fixed at both ends of the support plate 1, which are respectively located at the head and the foot of the bed. For the convenience of viewing the figure, in this embodiment, the head of the bed is at the back and the foot of the bed is at the front. The support frame 2 is a lifting support frame. The lifting support frame includes an outer cylinder and an inner rod. The inner rod is slidable up and down in the outer cylinder, and a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod is provided between the bottom surface of the inner rod and the bottom surface of the outer cylinder. Bearing mounting holes are respectively provided at the upper ends of the two support frames 2, and bearings are installed in the bearing mounting holes and connected to the rotating shafts 3. One end of one of the rotating shafts 3 extends out of the support frame 2 and is connected to a rotating mechanism, which is a motor. A bed body is connected between the two rotating shafts 3, and an angle sensor is connected to the rotating shaft 3; the bed body includes a bed board 4, and a human body protection fixing mechanism is provided on the bed board 4. The human body protection fixing mechanism in this example is a block 5 respectively set on the left and right sides of the bed board, so that the block 5 on the side moving downward during the tilting of the bed board will move toward the body. The stopper 5 moves in the same direction and gradually moves to fit the body, so the stopper 5 needs to be designed to be movable. There are many ways to realize the movement of the stopper from the left and right sides of the bed board to the middle. For example, blocks that can be stuck to the head and tail ends of the bed board 4 are respectively set at both ends of the stopper 5. The blocks on the left baffle and the blocks on the right baffle are respectively connected with a linear motion mechanism 8. The linear motion mechanism 8 is set along the left and right directions. The linear motion mechanism 8 is an electric telescopic rod, hydraulic cylinder or pneumatic cylinder connected to the bed board 4. Pressure sensors are respectively provided on the opposite sides of the two stoppers 5. A lifting support structure 14 is fixed on the lower middle part of both sides of the bed board 4 and the support plate 1. The lifting support structure 14 is a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod. The angle sensor and the pressure sensor are connected to the input end of the central controller, and the output end of the central controller is connected to the remote control, the motor, the linear motion mechanism 8, the lifting support structure and the lifting support frame.

[0057] The human body protection fixing mechanism also includes a body fixing device, which includes two slide rails 15 respectively located at the head and foot of the bed, and the two ends of the slide rails 15 are respectively connected to the two sides of the bed board 4. A bed curtain 17 that can slide along the slide rails 15 is provided between the two slide rails 15. The bed curtain 17 includes a plurality of support bars arranged in parallel, and two adjacent support bars are connected by a flexible connector, which is a rope or a quadrilateral telescopic structure. The left side of the bed curtain is connected to the left side of the bed board. The body fixing device also includes a traction mechanism controlled by a central controller, and the traction mechanism is a motor chain 22 (such as Fig.11 and 12As shown), the traction end 23 of the motor chain 22 is located in the slide rail 15 and connected to the right side of the bed curtain 17. The chain of the motor chain is extended to push the bed curtain to close the bed curtain, and the chain of the motor chain is retracted to unfold the bed curtain; a filling air bag is provided on the surface of the bed curtain 17 close to the human body, and an air pump is connected to the filling air bag, which is connected to the central controller. After the filling air bag is inflated, it can fix the human body on the bed board.

[0058] When the sleep-aiding bed is in use, the human body needs to lie flat on the bed board first, and the user sets the movement mode and movement cycle of the bed through the central controller according to the use requirements. If the angle adjustment range is set to 0° to ±360°, the soft curtain 10 needs to be unfolded, but the human body is not restrained at this time. When the user is lying on the bed to rest or fall asleep, the central controller will control the rotating mechanism according to the setting to start the bed body to rotate slowly within the range of -90° to 90° (the degree of slowness shall be based on the human body being unable to feel), wherein the bed body is horizontal at 0°, and the angle sensor detects the rotation angle of the shaft 3 in real time. When it is detected that the rotation angle of the shaft 3 is between -30° and 30°, the block 5 is located on both sides of the bed board and does not move. When it is detected that the rotation angle of the shaft 3 is greater than 30°, the central controller controls the linear motion mechanism 8 to move the block 5 on the right side. Move to the left, when the value detected by the pressure sensor on the right block 5 reaches the set value, the central controller controls the linear motion mechanism 8 to stop moving. Conversely, when it is detected that the rotation angle of the rotating shaft 3 is less than -30°, the central controller controls the linear motion mechanism 8 to move to the right with the left block 5. When the value detected by the pressure sensor on the left block 5 reaches the set value, the central controller controls the left linear motion mechanism 8 to stop moving. The sleep-aid bed can protect and fix the human body through the blocks 5 on both sides of the bed body to prevent the human body from sliding left and right along the bed board 4 and affecting sleep. Moreover, when the bed board is tilted to the side-lying position, the block will become the bed board that supports the body, which can realize the cyclic conversion of the human body between supine → left-side lying → supine → right-side lying, and can avoid maintaining a single sleeping posture for a long time and causing continuous pressure on local tissues. When it is detected that the rotation angle of the rotating shaft 3 is greater than +90° or less than -90°, the central controller controls the linear motion mechanism 8 to move the blocks 5 on the left and right sides to the middle. When the value detected by the pressure sensor on the block 5 reaches the set value, the central controller controls the linear motion mechanism 8 to stop moving. At the same time, the air pump starts to inflate the filling air bag to cover the human body and ensure the stability of the human body when the bed board is turned over. The lifting support frame can adjust the height of the head and foot of the entire bed respectively. For example, raising the head of the bed within a certain period can improve the breathing work, and raising the foot of the bed can improve the venous return rate. When the bed rotates, the lifting support structure descends to avoid hindering the rotation of the bed. When the bed stops, the lifting support structure rises to support the bed to keep it level.
