Description

Technical Field

[0001] This invention relates to the field of smart bedding technology, and in particular to a bedding device driven by artificial muscles. Background Technology

[0002] As people age, more and more people join the ranks of snorers. Snoring, commonly known as snoring, is mainly caused by airway obstruction or narrowing during sleep, leading to increased airway resistance. This obstructs airflow and causes the soft tissues of the throat to vibrate, producing the sound of snoring. When snoring, the body experiences pauses in breathing and temporary oxygen deprivation, which can cause a wide range of health problems. There are smart pillows on the market that monitor breathing and heart rate, and even products that can change pillow shape through airbag inflation to adjust sleeping posture and reduce sleep apnea.

[0003] However, the mainstream products currently use airbags as the device to change the shape of the pillow. The disadvantages of airbags are that they are not soft, have poor shape control precision, require air passages and air pumps for inflation, and the noise generated affects sleep. Summary of the Invention

[0004] The purpose of this invention is to provide an artificial muscle-driven bedding that can not only detect the position and posture of the human body on the bedding and detect the physiological parameters of the human body, but also effectively alleviate the problems of snoring and sleep apnea during sleep. It is noiseless, flexible, and highly practical.

[0005] To achieve the above objectives, the present invention provides an artificial muscle-driven bedding, comprising an upper bedding body filling layer and a lower bedding body filling layer. An artificial muscle deformation layer is provided on the lower side of the upper bedding body filling layer. The artificial muscle deformation layer consists of an artificial muscle module and a pressure sensor located on the upper surface of the artificial muscle module. A physiological parameter detection sensor is provided on the surface of the upper bedding body filling layer.

[0006] Preferably, one side of the artificial muscle deformation layer is bonded to the lower surface of the upper layer of the bedding body filling layer, and the artificial muscle module and the pressure sensor are bonded together as a whole.

[0007] Preferably, the artificial muscle modules are arranged as follows: at least two groups are arranged in the vertical direction of the human torso; and at least one group is arranged in the parallel direction of the torso.

[0008] Preferably, the artificial muscle module consists of a row of artificial muscle strips, which are arranged vertically on the human torso.

[0009] Preferably, the artificial muscle strip is a heat-shrinkable device or a heat-stretching device, and the device is heated by a single internal heating core or by an external heating element.

[0010] Preferably, the number of pressure sensors on the artificial muscle module is not less than two.

[0011] Preferably, the physiological parameter detection sensor includes sound sensors disposed on both sides, and a piezoelectric sensor and an electrocardiogram sensor disposed in the middle, wherein the number of sound sensors is not less than two.

[0012] Preferably, the bedding includes a signal acquisition system for detecting pressure sensor signals, physiological parameter sensor signals, and sound sensor signals, a main control system for analyzing human posture and physiological state through sensor signals and controlling the operation of the artificial muscle module, and a related power supply module.

[0013] Therefore, the artificial muscle-driven bedding of the present invention can not only detect the position and posture of the human body on the bedding and detect the physiological parameters of the human body, but also effectively alleviate the problems of snoring and sleep apnea during sleep. It is noiseless, flexible and highly practical.

[0022] Example 1

[0023] like Figure 1-3 As shown, this invention provides an artificial muscle-driven bedding system, comprising an upper bedding body filling layer 1 and a lower bedding body filling layer 3. An artificial muscle deformation layer 2 is provided on the lower side of the upper bedding body filling layer 1. One side of the artificial muscle deformation layer 2 is bonded to the lower surface of the upper bedding body filling layer 1. The artificial muscle deformation layer 2 consists of an artificial muscle module and a pressure sensor 9 located on the upper surface of the artificial muscle module. The artificial muscle module and the pressure sensor 9 are bonded together as a whole. The artificial muscle modules are arranged as follows: at least two sets are arranged vertically to the human torso; and at least one set is arranged parallel to the torso.

[0024] The artificial muscle module consists of a row of artificial muscle strip-shaped units 6, which are arranged vertically along the human torso. Each artificial muscle strip-shaped unit 6 consists of an artificial muscle material body and a heating core. The positive electrode 7 and negative electrode 8 of the heating core of the row of artificial muscle strip-shaped units are connected in parallel to the drive board. The current supplied by the drive board controls the heating of the artificial muscle strip-shaped units 6. After the temperature rises, the artificial muscle strip-shaped units 6 contract and deform. After the entire row deforms simultaneously, the upper layer 1 of the bedding body filling layer, which is bonded as a whole, is partially deformed.

[0025] The artificial muscle strip 6 employs either a heat-shrinking or heat-stretching device. Heating is achieved either through a single internal heating core or an external heating element. The preferred heating temperature range is 20–70 degrees Celsius. At least two pressure sensors 9 are present on the artificial muscle module, and their detection signals are connected to the control board.

[0026] The surface of the upper layer 1 of the bedding main filling layer is equipped with physiological parameter detection sensors. These sensors include piezoelectric and electrocardiogram (ECG) sensors 5 located in the middle of the upper layer 1. These sensors detect the shock waves of the human heartbeat. At least two sound sensors 4 are located on either side of the piezoelectric and ECG sensors 5. These sensors detect characteristic audio signals such as breathing and snoring. By analyzing the comparative values ​​of the propagation speed and direction of the sound signals from the two sound sensors 4, combined with the pressure sensor 9, the position and posture of the human body can be determined, particularly whether the face is facing upwards or to the sides.

[0027] This bedding system includes a signal acquisition system that detects signals from pressure sensors, physiological parameter sensors, and sound sensors; a main control system that analyzes human posture and physiological state through sensor signals and controls the operation of artificial muscle modules; and a related power supply module. Through the power supply module, main control system, and signal acquisition system, the system can better detect the human body's sleep state and make corresponding adjustments based on the sleep state, ensuring good sleep and effectively alleviating problems such as snoring and sleep apnea during sleep.

[0028] The bedding provided by this invention includes a smart pillow; a smart mattress; and smart neck, lumbar, and back support cushions.

[0029] When in use, when a person's head is on the pillow, multiple pressure sensors 9 determine the force state, and the sound sensors 4 on both sides determine the breathing sound, thereby obtaining the position of the head on the pillow and the orientation of the head and face. The sound sensors 4, along with the piezoelectric and electrocardiogram sensors 5, monitor the characteristic audio of snoring, breathing frequency, and breathing interval. If prolonged snoring or sleep apnea occurs, the main board sends a command to the drive board, which causes the corresponding artificial muscle module to contract, causing the pillow to deform, thereby causing the human head to rotate, opening the human's breathing passage, and relieving snoring and sleep apnea.

[0030] Multiple pressure sensors 9 determine the force state and detect the contact position between the person and the mattress. The main board sends instructions to the drive board, which causes the corresponding artificial muscle modules to contract, causing local deformation of the mattress and moving the person's lying posture to a healthier position. At the same time, the support force of the mattress on different parts of the body can be adjusted.

[0031] Multiple pressure sensors 9 determine the force state and detect the contact position of the neck, waist, and back cushions. They determine the size of the neck, waist, and back, and send instructions to the drive board via the motherboard. The drive board causes the corresponding artificial muscle modules to contract, which in turn causes local deformation of the back cushions, providing appropriate lateral clamping force to the waist and neck and appropriate support force to the back. At the same time, the support force of the neck, waist, and back to different parts of the body can be adjusted.

[0032] Therefore, the artificial muscle-driven bedding of the present invention can not only detect the position and posture of the human body on the bedding and detect the physiological parameters of the human body, but also effectively alleviate the problems of snoring and sleep apnea during sleep. It is noiseless, flexible and highly practical.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
