Description

Technical Field

[0001] This invention relates to the field of smart furniture technology, and in particular to a novel smart bed. Background Technology

[0002] As living standards improve, users' functional needs for beds have shifted from simply "supporting sleep" to "multi-functional comfort adjustment." Traditional beds are mostly fixed structures that only provide basic lying support and cannot be adjusted to suit user needs. For example, users need to rely on pillows to support their upper body when reading or watching movies, and maintaining this posture for a long time can easily lead to back pain. Although some existing smart beds have back or leg adjustment functions, they have limitations in the adjustment areas, such as lacking fine adjustment for the arms and waist, poor adjustment stability, uneven force distribution in the support structure making it prone to wobbling, and limited functionality, such as difficulty in smoothly switching between lying and sitting positions. These issues fail to meet users' needs for comfortable and diverse usage scenarios.

[0003] To address the aforementioned shortcomings, this invention proposes a novel smart bed that optimizes the design of its support, adjustment, and support structures to achieve coordinated adjustment of multiple parts, balancing stability and functionality, and adapting to various usage scenarios such as lying down and sitting. Summary of the Invention

[0004] To address the limitations of existing beds in terms of adjustment functions, poor stability, and low adaptability to different scenarios, the present invention aims to provide a novel smart bed that enables coordinated adjustment of the torso, arms, thighs, and calves, ensuring a stable adjustment process and allowing for smooth switching between lying and sitting postures, thereby improving user comfort.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel intelligent bed includes a support structure, a supporting structure, an adjustment structure, and an equipment box. These structures work together to achieve shape adjustment and stable support. The specific structure is as follows:

[0007] Support structure: core support and adaptation to multiple parts;

[0008] The support structure is the core component that comes into direct contact with the human body. It supports the human body and changes shape according to the adjustment structure. Its components include:

[0009] Torso: The basic framework of the supporting structure, used to support the human torso;

[0010] Head: Located at one end of the torso;

[0011] Arms: Symmetrically positioned on both sides of the torso near the head, each arm has a fixed pivot on its underside. One end of the pivot is fixedly connected to the underside of the torso, allowing the arm to rotate horizontally to accommodate the user's natural arm placement or movement needs.

[0012] Waist connection structure: Located at the end of the torso furthest from the head, it consists of two hinged plates. The hinged connection allows for rotation at a certain angle, enabling the body to adjust between sleeping and sitting positions.

[0013] Thigh: One end connects to the waist connection structure away from the torso, and the other end connects to the calf through the leg connection structure; the leg connection structure is made of elastic and stretchable material, which has the ability to stretch and extend.

[0014] Lower leg: The end away from the thigh is equipped with a foot. The foot is a sloping plate structure that conforms to the curvature of the human foot and is used to support the foot.

[0015] Adjustment structure: power drive and precision adjustment;

[0016] The adjusting structure connects with the supporting structure, providing power for shape changes and enabling movements such as lifting the thigh, bending the lower leg, and rotating the arm. Its components include:

[0017] Fixed pivot: In addition to connecting the arm, there are two other fixed pivots symmetrically set on the bottom side of the torso near the two side edges and connected to the bottom side of the thigh. This allows the thigh to swing around the pivot, completing the "leg lift" or "leg lower" movement.

[0018] Electric telescopic rod: It is set at the center of the bottom of the torso. One end is fixed to the torso, and the other end is connected to the adjustment frame through a hinge. The end away from the electric telescopic rod is hinged to the waist connection structure. When the electric telescopic rod extends or retracts, the waist connection structure can be rotated through the adjustment frame, thereby driving the thigh to rise or fall.

[0019] Linear lead screw: One end is hinged to the bottom of the thigh, and the other end is hinged to the bottom of the calf; when the linear lead screw extends or retracts, it can pull the calf to bend around the thigh, adapting to the natural placement of the calf when sitting.

[0020] Support structure: stable support and overall fine-tuning

[0021] The support structure is located at the bottom of the equipment box and can be used to store and place items.

[0022] Base plate: A rectangular plate is used as the foundation of the supporting structure and is placed on the ground;

[0023] Electric cylinders: There are three in number, arranged in an isosceles triangle on the upper surface of the base plate. The triangular arrangement can maximize the distribution of force and improve the stability of the support.

[0024] Universal ball joints: installed at the top of each electric cylinder; the top of the universal ball joint is fixedly connected to the bottom of the equipment box, and the height of the top is adjusted by the three electric cylinders, thereby driving the torso to adjust the tilt.

[0025] Equipment box: The internal integrated installation of controllers, such as PLC controllers, power modules and wiring. The controller can receive signals from the user's remote control and drive the electric telescopic rod, linear screw and electric cylinder to work together to achieve shape adjustment.

[0026] The beneficial effects of this invention are as follows:

[0027] Highly adjustable: The fixed pivot allows for horizontal rotation of the arms and thighs, while the electric telescopic rod and linear screw allow for raising the thighs and bending the calves. It can cover multiple parts of the torso, arms, and legs for adjustment, and is suitable for various scenarios such as lying down, sitting, reading, and watching movies.

[0028] Obviously, based on the above description of the present invention, and according to common technical knowledge and conventional methods in the field, various other modifications, substitutions or alterations can be made without departing from the basic technical concept of the present invention.

[0038] To address the technical problems in the background section, a novel smart bed is proposed as follows:

[0039] Combination Figures 1-3 As shown, this invention provides a novel intelligent bed.

[0040] I. Component Assembly

[0041] Assembly of supporting structure 2:

[0042] The head 206 is fixed to one end of the torso 201 with bolts, and the arm 202 is installed on both sides of the torso 201 via a fixed pivot 301;

[0043] One end of the waist connection structure 203 is bolted to the other end of the torso 201, and the other end is bolted to the thigh 204;

[0044] The thigh 204 is connected to the lower leg 205 via the leg connection structure 208, and the foot 207 is fixed at the end of the lower leg 205.

[0045] Adjustment structure 3 assembly:

[0046] Two sets of fixed rotating shafts 301 are symmetrically welded to the bottom side of the torso 201 and hinged to the bottom side of the thigh 204;

[0047] The bottom end of the electric telescopic rod 302 is welded to the center of the bottom of the torso 201, and the top end is hinged to the adjustment frame 303 through a pin. The other end of the adjustment frame 303 is hinged to the waist connection structure 203.

[0048] The two ends of the linear lead screw 304 are respectively hinged to the bottom sides of the thigh part 204 and the lower leg part 205 via pins.

[0049] The support structure 1 is assembled with the equipment box 4:

[0050] Three electric cylinders 102 are welded to the base plate 101 in an isosceles triangle configuration, and a universal ball 103 is installed at the top of each electric cylinder 102.

[0051] The bottom of the equipment box 4 is welded and fixed to the top of the three universal balls 103, and the top of the equipment box 4 is welded and fixed to the bottom of the body 201.

[0052] The PLC controller and power module are installed inside the equipment box 4. The controller is connected to the electric telescopic rod 302, the linear screw 304, and the electric cylinder 102 through lines, and is also connected to an external remote control receiver module.

[0053] II. Function Implementation: Taking the switching from lying down to sitting posture as an example

[0054] Initial state: lying down, with the electric telescopic rod 302 and linear lead screw 304 both in the retracted state, the thighs 204 and calves 205 and the torso 201 kept horizontal, the arms 202 in the naturally extended position, the electric cylinder 102 in the medium stroke, and the bed as a whole in a horizontal position.

[0055] Switch to a seated position:

[0056] The user sends a "sitting posture" command via remote control, and the controller drives the electric cylinder 102 to work together: the electric cylinder 102 on the headboard side extends, and the two electric cylinders 102 on the footboard side shorten slightly, so that the equipment box 4 drives the support structure 2 to tilt 10-15° towards the headboard side to adapt to the upper body support of the sitting posture.

[0057] The electric telescopic rod 302 extends, pushing the adjustment frame 303 to rotate upward. The adjustment frame 303 drives the waist connection structure 203 to rotate, thereby causing the thigh 204 to lift upward by 30-45° around the fixed pivot 301, thus achieving "leg lifting".

[0058] The straight lead screw 304 is shortened, pulling the lower leg 205 to bend downwards by 20-30° around the thigh 204, adapting to the natural downward hanging of the lower leg;

[0059] The arm section 202 can be rotated to a comfortable position for the user via the fixed pivot 301, such as rotating inward by 15° to facilitate the placement of the arm.

[0060] Returning to the lying position: The controller drives each component to move in the opposite direction. The electric cylinder 102 resets to make the bed level. The electric telescopic rod 302 and the linear screw 304 retract to restore the thighs 204 and calves 205 to the horizontal position. The arm part 202 rotates back to the initial position.
