This can be very difficult for users with less strength, and may even require assistance from others.

[0003] Furthermore, as living standards improve, people's demand for beds increases, but the market currently lacks hardware designs that can fully meet user needs and provide comprehensive support.

[0004] Based on the above, this utility model is hereby proposed. Summary of the Invention

Detailed Implementation

[0026] The utility model will be further described below with reference to the accompanying drawings and embodiments, but the scope of the utility model is not limited to the description.

[0027] Example 1: As Figures 1-5 As shown, according to a first aspect of the present invention, a lifting bed frame for a multifunctional bed is provided, comprising:

[0028] Bed frame 2;

[0029] The bed board assembly includes a middle board and side boards arranged on both sides of the middle board. The middle board and the side boards are connected by a hinge. The middle board facing the bed frame 2 is connected to the bed frame 2 by an electromagnet 7, so that the middle board has a first state of magnetic attraction and a second state of magnetic release.

[0030] The hydraulic device 3 cooperates with the bed board assembly. When the intermediate plate is in the second state, the hydraulic device 3 is used to drive the bed board assembly to be movably set along a preset direction to achieve lifting and lowering.

[0031] Furthermore, four hydraulic devices 3 are provided: two for engaging with the side plates on one side of the middle board, and the other two for engaging with the side plates on the other side of the middle board. The middle bed board facing the bed frame 2 may have a metal block that engages with the electromagnet 7, or the middle bed board may be made of metal. The four hydraulic devices can be connected as a whole via connecting rods, or they can be connected to the bed frame 2. Each hydraulic device 3 includes a hydraulic rod 10 and a hydraulic end cap 9. An integrated pressure regulating valve 11 forms a sealed cavity with the hydraulic rod 10 for extension and retraction control. The extension and retraction of the hydraulic rod 10 drives the hydraulic end cap 9 to move vertically, thereby achieving vertical movement of the bed board and providing additional load-bearing capacity. Furthermore, an adjustable mattress can be configured on the bed board assembly.

[0032] Furthermore, the bed legs of the bed frame 2 are designed with high feet to facilitate the entry and cleaning of the robot vacuum cleaner.

[0033] According to a second aspect of the present invention, a multifunctional bed is provided, including a lifting bed frame, a first tilting device, and a second tilting device. There are a total of four side panels, with two first side panels located on one side of the middle panel and two second side panels located on the other side of the middle panel. The first tilting device cooperates with the first side panel, and the second tilting device cooperates with the second side panel.

[0034] Furthermore, the first tilting device includes a first servo motor 8 and a front lever 16; the first servo motor 8, mounted on the bed frame 2, drives the front lever 16 to rotate, and the rotation of the front lever 16 drives the first side plate to follow the movement.

[0035] The second tilting device includes a second servo motor 15 and a rear lever 6; the second servo motor 15, mounted on the bed frame 2, drives the rear lever 6 to rotate, and the rotation of the rear lever 6 drives the second side plate to follow the movement.

[0036] Furthermore, the front moving rod 16 is a single rod; the rear moving rod 6 includes a first rod, a second rod, and a third rod. One end of the first rod is connected to the output end of the second servo motor 15, the other end of the first rod is hinged to one end of the second rod, the other end of the second rod is hinged to one end of the third rod, and the other end of the third rod is hinged to the bed frame 2.

[0037] For example, two sets of each of the first and second tilting devices are used.

[0038] The specific working process is as follows: The tilting device is used to control the lifting action of the five-section bed board, which can realize the bed adjustment in multiple modes. This part is driven by four servo motors installed inside the bed frame, and the height and angle of the bed board are controlled by the front and rear moving rods.

[0039] Furthermore, it also includes a robotic arm device 4, which comprises three sets: one set is installed on the bed frame 2 near the foot of the bed, and the other two sets are installed on the two sides of the bed frame 2 adjacent to and opposite to the foot of the bed. That is, robotic arm devices 4 are provided on three sides except for the head of the bed.

[0040] Furthermore, the robotic arm device 4 includes a lead screw module 13, a robotic arm, and an end effector. The robotic arm includes a robotic arm base, a telescopic cylinder 14, and connecting rods. The nut seat of the lead screw module 13 is connected to each robotic arm base to drive the robotic arm to move along the axial direction of the lead screw of the lead screw module 13. One end of the telescopic cylinder 14 is connected to the robotic arm base, and the other end of the telescopic cylinder 14 is connected to one end of a series of sequentially connected connecting rods. The end effector is installed at the other end of the series of sequentially connected connecting rods. Exemplarily, the end effector adopts a flexible clamping device.

[0041] In the above, the telescopic cylinder 14 adopts a two-stage telescopic mechanism and is driven by a stepper motor. Each link is controlled by a servo motor 12 to rotate. Through the cooperation of the lead screw module 13, the telescopic cylinder 14, and the servo motor 12, the end effector can complete multi-degree-of-freedom motion: for example, the robotic arm can move horizontally through the lead screw module 13, and extend radially through the telescopic cylinder 14. The servo motors 12 in various parts control the robotic arm to complete motion in other directions, realizing the opening, closing, bending, and rotation of the robotic arm.

[0042] Example 2: Based on Example 1, the robotic arm device 4 in a multifunctional bed can also be equipped with a visual recognition camera (camera) for image acquisition and motion planning by the control device 5, enabling the collaborative work of multiple robotic arms. For example, when the middle plate is in the second state, the hydraulic device 3 lifts the bed board assembly, cooperating with the robotic arm to complete the mattress cover replacement function; its internal extension and retraction are mainly controlled by hydraulic rods. When the middle plate is in the first state, the hydraulic device 3 does not work, the bed board assembly is not lifted, and the robotic arm completes the quilt folding function.

[0043] Further, refer to Figure 5 The system also includes a sensing device 1, which contains multiple sensors embedded in the bottom of the bed board. The sensing device 1 houses an infrared sensor, a vibration sensor, a temperature sensor, a light sensor, a gravity sensor, and a heart rate sensor. It can monitor the user's heart rate, weight, and other data in real time. Simultaneously, it combines the infrared and vibration sensors to measure the user's sleep posture, and the temperature and light sensors to sense the user's current environment. The data collected by the sensing device 1 is uploaded to an IoT platform via a control device 5. A trained deep learning algorithm model calculates and analyzes the data to obtain sleep duration, number of turns, sleep depth, and other data, which are then displayed on a webpage. Through these steps, the system provides the user with specific values ​​and change curves of sleep data on the webpage, along with a comprehensive health analysis report.

[0044] Optionally, based on this embodiment, the present invention can be easily expanded to include intelligent features. The following optional implementation process is provided: Different modes can be selected via a mobile app or remote control. A memory mode can be activated. When the sensor 1 detects that certain conditions are met, the smart sleep management bed will automatically activate the corresponding mode. For example, if the sensor detects that the user has been sitting in bed for a long time, it will automatically activate the reading mode. An embedded voice module determines the function operation associated with the command words and sends the corresponding parameters to the control device 5 to achieve voice control. Users can select four function modes—anti-snoring mode, wake-up mode, pregnant / elderly mode, and work / reading mode—by clicking the corresponding mode button on the mobile app. Four servo motors driving the tilt mechanism activate the forward and backward levers 6 to control the height and angle of the five-section bed board. In anti-snoring mode, the headrest (first side board) is raised from 0° to 12°, an angle that helps intervene in snoring. In wake-up mode, the headrest is raised from 0° to 20°, used in conjunction with an alarm clock for gentle wake-up. In pregnant / elderly mode, the headrest is raised from 0° to 60° and the legrest (second side board) from 0° to 40°, allowing for one-button adjustment for getting up at night or lying down. In work / reading mode, the headrest is raised from 0° to 55° and the legrest from 0° to 30°, allowing for one-button control of lying down or sitting up. When the folding mode is selected, the control device 5 receives the command and controls the robotic arm 4 to fold the bed. The camera on the robotic arm 4 collects information about the bed surface and feeds it back to the control device 5, which then sends another command to the robotic arm 4 to achieve closed-loop control and begin folding the bed. After folding, the control device 5 controls the servo motor 12, the telescopic cylinder 14, and the lead screw module 13 to retract the robotic arm back under the bed. Furthermore, users can customize the tilt angles of the head and tail sections of the bed to meet their individual needs. Control devices 5 are connected to each actuator via a CAN bus and are equipped with a safety interlock mechanism. An embedded voice module integrates a noise-canceling microphone array to recognize user commands. Applying the above technical solutions, this invention, by integrating biosensing technology, servo control algorithms, and IoT technology, constructs a closed-loop "perception-decision-execution" system, achieving intelligent autonomous operation of over 90% of functions while maintaining redundancy in manual control. Compared to traditional products, this design not only improves sleep comfort but also extends to value-added services such as health monitoring and household assistance, forming an intelligent ecosystem that can continuously upgrade according to user needs.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
