DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] When people sleep, sometimes they lie flat, sometimes they sleep on their sides, and sometimes they sleep in an embrace with their spouses. When lying flat, if the mattress can be adjusted according to the concave and convex curves of the human body, so that the forces on all parts of the whole body are evenly distributed, or the local part can be lifted or lowered to increase or decrease the force on that part, it will have a certain relieving effect on human fatigue. When sleeping on the side, after a long time, a person's arm is very likely to get numb. If the mattress at the arm part can be appropriately lowered to reduce the pressure on the arm part, it can increase the comfort when sleeping on the side. When sleeping in an embrace with a spouse, one or both of their arms are pressed under the other's body, and after a long time, it is very likely to get numb. If the mattresses at the arm parts of both sides can be appropriately lowered to reduce the pressure on the arm parts, it can increase the comfort when sleeping in an embrace, thus enhancing the relationship between husband and wife.

[0021] With the advent of the AI big data era, the trend of applying artificial intelligence to furniture is becoming more and more obvious. An intelligent mattress with the ability of autonomous learning can, under the empowerment of AI, not only accurately judge the sleeping posture of the owner and each part of the human body corresponding to the mattress, but also make adjustments to the bed surface curve, and can learn the master's mattress curve pressure habits and preferences, thereby increasing happiness and providing a foothold for new quality productivity in the traditional furniture industry.

[0022] As Figures 1 to 8 shown, an intelligent mattress based on intelligent control of the present invention includes a surface layer 1 and a bottom layer 2. The bottom layer 2 includes a frame 3 and a plurality of platform fixing frames 4 arranged in the frame 3.

[0023] In the present invention, a lifting device is arranged in the platform fixing frame 4.

The lifting mechanism 52 includes a lifting motor 521, a motor mounting plate 522, a limiting frame 525 and a lifting component. The motor mounting plate 522 is fixedly connected to the bottom of the platform fixing frame 4, and the lifting motor 521 is connected to the motor mounting plate 522. The limiting frame is arranged on the periphery of the lifting platform 51 and is used to limit the balance of the lifting platform 51 when it rises and falls.

The lifting block 523 is fixedly connected to the lifting platform 51, and the screw rod 524 is fixedly connected to the lifting platform 51. The screw rod 524 is driven by the lifting motor 521 to rotate. Since the screw rod 524 is threadedly connected to the lifting block 523 and the lifting block 523 is arranged on the platform fixing frame 4, the screw rod 524 can perform a lifting motion.

[0027] Within the present invention, the surface layer 1 is sewn and connected to the lifting platform 51, making the curve formed by the lifting platform 51 smoother.

[0028] Within the present invention, a sponge 512 is provided inside the lifting platform 51 to improve softness, and a spring 513 is also provided inside the lifting platform 51, which not only increases elasticity but also prevents the lifting platform 51 from tilting.

[0029] Within the present invention, the bottom plate of the lifting platform 51 is fixedly connected to the screw rod 524, which can make the connection of the screw rod 524 firm.

[0030] Specifically, the platform fixing frame 4 is used to install, fix and carry the lifting motor 521. The platform fixing frame 4 is provided with a motor pit, which is beneficial to the fixing of the lifting motor 521, reducing vibration and displacement. Each platform fixing frame 4 is provided with a lifting motor 521, and the lifting motor 521 is fixedly connected inside the motor pit through a motor mounting plate 522; the platform fixing frame 4 positions the lifting platform 51, making it not easy to tilt and displace.

[0031] The present invention provides several embodiments of the lifting mechanism 52 as follows: Embodiment 1 of the lifting mechanism 52: Inside the lifting mechanism 52, the bottom of the lifting motor 521 is installed on the motor mounting plate 522, its output shaft faces upward and is fixedly connected to the screw rod 524, and the screw rod 524 is fixedly connected to the lifting platform 51. By the operation and rotation of the lifting motor 521, the lifting of the lifting platform 51 is driven.

[0032] Embodiment 2 of the lifting mechanism 52: The bottom of the lifting motor 521 is mounted on the motor mounting plate 522. Its output shaft faces upward and is fixedly connected to the screw rod 524. The screw rod 524 is axially connected to the first bevel gear 526. The first bevel gear 526 is meshingly connected to the second bevel gear 527. The gear screw 529 is axially connected to the second bevel gear 527. The section of the gear screw 529 axially connected to the second bevel gear 527 is a smooth rod, and the other section is provided with an external thread and is meshingly connected to the rack 528. The rack 528 is fixedly connected to the bottom of the lifting platform 51. By the operation and rotation of the lifting motor 521, the lifting of the lifting platform 51 is driven.

[0033] Embodiment Three of the Lifting Mechanism 52: The bottom of the lifting motor 521 is mounted on the motor mounting plate 522. Its output shaft faces upward and is connected to the gear screw 529. One section of the gear screw 529 is a smooth rod, and the other section is provided with an external thread and is meshingly connected to the rack 528. The rack 528 is fixedly connected to the bottom of the lifting platform 51. By the operation and rotation of the lifting motor 521, the lifting of the lifting platform 51 is driven.

[0034] Within the present invention, the lifting platform 51 includes a bottom plate, a spring 513, a sponge 512, and a fabric. There is a screw hole in the middle of the bottom plate and it is used for fixedly connecting the screw rod 524. The spring, sponge, fabric, and pressure sensor 511 are sequentially placed on it. The spring 513 plays a role in stabilizing the lifting platform 51 and making it not easily skewed.

[0035] Within the present invention, the pressure sensor 511 can be a semiconductor piezoresistive pressure sensor or a variable resistance type pressure sensor. The semiconductor piezoresistive pressure sensor is in the shape of a thin film and can be placed on the fabric of the lifting platform 51. It can cause the resistance to change according to the magnitude of the pressure, and then control the motor. The variable resistance type pressure sensor is composed of a variable resistor, a spring, and a contact piece. When an external force presses, the spring expands and contracts, and the electrode contact piece forms a resistance value change at different positions of the resistor, and then controls the motor. It can be installed inside the lifting platform 51.

[0036] Within the present invention, the surface layer 1 is laid on the outermost layer, covering the entire bed surface, and is a fabric with a certain stretchability. When the lifting platform 51 forms a curve, it has the effect of making the curved surface smoother.

[0037] Within the present invention, the control circuit board is provided with a main control module for processing user signals and coordinating the work of each module, a collection module for receiving data transmitted by the pressure sensor, an analysis module for data analysis, an intelligent adjustment module for data adjustment, a wireless communication and networking module for receiving and transmitting wireless signals, a power management module for providing a stable voltage, a motor drive module for controlling the lifting of the lifting motor, and a storage module for storing data.

[0038] Specifically, the control panel is the control center responsible for receiving instructions, processing information, sending instructions, etc. The control panel can be a remote control device, a touch panel, or a mobile phone APP, which plays the role of human-bed interaction. The present invention is controlled through the control panel to achieve the curve or surface of the bed surface; the power supply wire is installed at the bottom of the platform fixing frame 4 and is used to connect to the power supply to supply power to the lifting motor 521; the sensor wire connects the electrodes of the pressure sensor and the circuit board, is installed at the bottom of the platform fixing frame 4 and is arranged in an orderly manner.

[0039] In the present invention, the power management module supplies power. The acquisition module receives the data information transmitted by the pressure sensor and simultaneously sends the data information to the analysis module. The analysis module analyzes it to draw a pressure graph, and at the same time compares it with the preset data pre-stored in the storage module to form a bed surface curve graph of the human body sleeping position. Then, the intelligent adjustment module controls each lifting motor 521 to adjust according to the data information of the bed surface curve graph through the motor drive module, and adjusts the entire bed surface into the actual paving of the bed surface curve graph; moreover, it is also possible to receive the hand-drawn bed surface curve graph of the display screen, small program, or APP through wireless communication and networking module and store it in the storage module as the preset comparison data.

[0040] In the present invention, the wireless communication and networking module is used to receive the wirelessly transmitted data from the display screen, small program, or APP.

[0041] The present invention provides a control method for an intelligent mattress based on intelligent control, including the following steps: Step S1: A person lies on the intelligent mattress; Step S2: In the automatic mode, each pressure sensor sends the data it collects to the control circuit board. The analysis module in the control circuit board analyzes and processes the collected data information, draws a pressure graph, and at the same time compares it with the pre-stored preset data to form a bed surface curve graph of the human body sleeping position. Thus, the control circuit board controls each lifting motor to work according to the bed surface curve graph, so that the surface layer of the intelligent mattress conforms to the bed surface curve graph; Or, in the zero-gravity mode, the acquisition module in the control circuit board collects the data transmitted by each pressure sensor, and the control circuit board controls each lifting motor to work until the data transmitted by each pressure sensor collected by the acquisition module is the same and then stops working; Or, in the custom mode, the bed surface curve graph is hand-drawn through the display screen, small program, or APP. The wireless communication and networking module wirelessly receives the bed surface curve graph, and the control circuit board controls each lifting motor to work according to the bed surface curve graph, so that the surface layer of the intelligent mattress conforms to the bed surface curve graph.

[0042] Specifically, the lifting platform 51 is provided with a pressure sensor 511. One pressure sensor 511 corresponds to one lifting motor 521, which is used to collect pressure data and serve as the basis for the action instructions of the corresponding lifting motor 521. The present invention is provided with a number of platform fixing frames 4 (equivalent to pixel points). When there is someone on the bed, the control circuit board will collect the pressure information of each pressure sensor 511. The control panel in the control circuit board processes all the data, draws a pressure graph, and can judge whether a person is lying, what the sleeping position is, and the body parts by comparing with the preset data pre-stored in its storage module. Finally, a portrait of the human sleeping position and body parts is obtained, and then each relevant lifting motor 521 is actuated to obtain a bed surface curve beneficial to human comfort. The storage module stores a variety of sleeping position graphs, which is reflected as the "automatic mode" function on the control button. In this mode, the bed surface will act according to the drawn preset curve. There can also be a "zero-gravity mode" function. In this mode, the lifting motor 521 will perform lifting actions according to the collected pressure data, and finally make the pressure of each pressure sensor 511 consistent, so that the pressure on each "pixel point" of the bed surface by the human body is balanced, achieving a "zero-gravity" sense of comfort; it can also be a "custom mode", where the sleeper hand-draws a bed surface curve on the control screen, and the lifting motor 521 responds to obtain the curved surface for lying and sleeping desired by the sleeper.

[0043] The present invention can achieve fine local curve adjustment, so as to realize a more accurate personalized fitting curve of the mattress curve from the head to the feet of the sleeper; if when the human body sleeps on its side and the pressure from the arm to the shoulder is relatively large, this posture is likely to cause the arm to go numb, while the present invention can avoid this problem; when one of the couple presses the other's arm while sleeping, the pressed arm is also likely to go numb, and the present invention can form a groove to relieve the pressure on the pressed side.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
