[0043] An embodiment of the present invention provides an electric bed, such as Figure 1 and Figure 2 As shown, the electric bed includes a bed body 1, an adjustment module 2, a monitoring module 3 and a control module 4.

[0044] The monitoring module 3 is arranged on the bed body 1 and is used to collect user data. The monitoring module 3 refers to a module capable of collecting user data. In some embodiments, the user data includes one or more of heart rate, pressure, respiration, and temperature. In some embodiments, the monitoring module 3 includes one or more of a pressure sensor, a temperature sensor, a heart rate sensor, and a respiration sensor, so that one or more user data of pressure, temperature, heart rate, and respiration can be collected.

[0045] The bed body 1 includes a plurality of bed boards 11, and the angles of the plurality of bed boards 11 can be changed. In some embodiments, the monitoring module 3 can be arranged on the bed board 11 near the chest area of ​​the human body. In some embodiments, the bed body 1 also includes a mattress, and the mattress is arranged on the plurality of bed boards 11, and the monitoring module 3 can be arranged on the mattress near the chest area.

[0046] The adjustment module 2 is connected to the bed board 11, and the adjustment module 2 is used to adjust the angles of the multiple bed boards 11. The adjustment module 2 refers to a module capable of adjusting the angles of the bed boards 11. In some embodiments, the adjustment module 2 includes an electric push rod, which includes a motor 21 and a push rod (not shown in the figure), and the motor 21 drives the push rod to extend and retract to adjust the angle of the bed board 11. In some embodiments, there are multiple electric push rods, and multiple bed boards 11 are adjusted by multiple electric push rods, so that different bed boards 11 can be adjusted to different angles.

[0047] The input end of the control module 4 is electrically connected to the monitoring module 3, and the output end of the control module 4 is electrically connected to the adjustment module 2. The control module 4 is used to obtain user data, determine the bed board angle information based on the user data, and drive the adjustment module 2 to adjust the angle of each bed board 11 based on the bed board angle information. Among them, the control module 4 refers to a module that can process the collected user data and then intelligently adjust the angle of the bed board 11 according to the preset algorithm and model. In some embodiments, the control module 4 includes an MCU, and the full name of MCU is Micro controller Unit, that is, a microcontroller, which is a powerful and flexible microcomputer. The bed board angle information refers to information about the target angle of each bed board 11. Driving the adjustment module 2 to adjust the angle of each bed board 11 based on the bed board angle information means adjusting the angle of each bed board 11 to the angle corresponding to the bed board angle information. Different users have different requirements for the angle of the bed board 11 of the electric bed. By determining the bed board angle information according to the user data, the obtained bed board angle information can be made more in line with user needs.

[0048] In the above scheme, the monitoring module 3 collects user data, and then the control module 4 obtains the user data, determines the bed board angle information based on the user data, and drives the adjustment module 2 to adjust the angle of each bed board 11 based on the bed board angle information. Therefore, the obtained bed board angle information can be more in line with user needs. Compared with the related art of adjusting the electric bed to a fixed angle to help the user sleep, this scheme can adjust the angle of the bed board 11 according to the user data, so that the obtained angle of the bed board 11 can be more in line with user needs, solving the problem that the sleep aid is not intelligent and humane enough.

[0049] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the multiple bed boards 11 include a back bed board 111, a leg bed board 112 and a waist bed board 113. The back bed board 111 refers to the area where the back of the user should be when lying on the electric bed, the leg bed board 112 refers to the area where the legs of the user should be when lying on the electric bed, and the waist bed board 113 refers to the area where the waist of the user should be when lying on the electric bed.

[0050] The bed board angle information includes the waist angle; the control module 4 is specifically used to: obtain the working mode of the electric bed; when the working mode is the sleep aid mode, determine the waist angle based on the user data; drive the adjustment module 2 to adjust the back bed board 111, the leg bed board 112 and the waist bed board 113 to the initial angle; based on the waist angle, drive the adjustment module 2 to perform a preset number of waist-pushing operations, and the waist-pushing operation is to adjust the waist bed board 113 from the initial angle to the waist angle, and then adjust the waist bed board 113 from the waist angle to the initial angle.

[0051] Among them, the sleep-aiding mode refers to a mode that provides users with a more comfortable and healthy sleeping experience. In some embodiments, the electric bed may be provided with an operation panel, and the user operates the operation panel, and the control module 4 receives a signal from the operation panel to make the electric bed enter the sleep-aiding mode, so that the electric bed enters the sleep-aiding mode. In some embodiments, the electric bed is configured with a corresponding APP, and the user adjusts the working mode of the electric bed through the APP. The control module 4 communicates with the APP to receive an instruction for the electric bed to enter the sleep-aiding mode, so that the electric bed enters the sleep-aiding mode.

[0052] The waist angle refers to the target angle of the waist bed board 113. The initial angle refers to the default angle of the back bed board 111, the leg bed board 112 and the waist bed board 113 before the electric bed is not adjusted by the user. In some embodiments, the initial angle is 0 degrees, at which time the back bed board 111, the leg bed board 112 and the waist bed board 113 are all in a horizontal state. In some embodiments, the initial angle is 1 degree-5 degrees. In some embodiments, the initial angles of the back bed board 111, the leg bed board 112 and the waist bed board 113 are the same. In some embodiments, the initial angles of the back bed board 111, the leg bed board 112 and the waist bed board 113 are partially the same. In some embodiments, the initial angles of the back bed board 111, the leg bed board 112 and the waist bed board 113 are all different. The initial angles of the back bed board 111, the leg bed board 112 and the waist bed board 113 are not specifically limited here.

[0053] The preset number of times refers to the number of executions of the waist-lifting operation that is preset in advance. By executing the preset number of waist-lifting operations, the waist bed board 113 is adjusted from the initial angle to the waist angle during the waist-lifting operation, and then the waist bed board 113 is adjusted from the waist angle to the initial angle, that is, the user's waist can be lifted up multiple times during the waist-lifting operation to achieve relaxation of the user.

[0054] The above scheme determines the waist angle based on the user data, and then makes the waist bed board 113 lift up to the waist angle multiple times, so as to lift the user's waist to a proper angle according to the user's situation, so as to better relax the user.

[0055] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the bed board angle information also includes the leg angle and the back angle. The leg angle refers to the target angle of the leg bed board 112, and the back angle refers to the target angle of the back bed board 111. The control module 4 is specifically used for: when the working mode is the sleep-aiding mode, determining the leg angle and the back angle based on the user data; when the preset number of waist-supporting operations are completed, entering the coaxing mode. Among them, the coaxing mode refers to a specific mode set by the electric bed for coaxing the user to sleep. The coaxing operation is the operation that the electric bed should perform when entering the coaxing mode.

[0056] When entering the coaxing mode, the control and adjustment module 2 drives the back bed board 111 to adjust to the back angle at a first speed; the control and adjustment module 2 continuously performs the coaxing operation, wherein the coaxing operation includes: driving the back bed board 111 to adjust from the back angle to the initial angle at a first speed while driving the leg bed board 112 to adjust to the leg angle at a second speed; then driving the leg bed board 112 to adjust from the leg angle to the initial angle at a second speed while driving the back bed board 111 to adjust to the back angle at the first speed.

[0057] The first speed refers to the movement speed of the back bed board 111, and the second speed refers to the movement speed of the leg bed board 112. The first speed and the second speed may be the same or different, and are not specifically limited here. By adjusting the back bed board 111 and the leg bed board 112 in the above manner, the back bed board 111 and the leg bed board 112 will form a shape similar to a cradle, and then rock to coax the user to sleep.

[0058] Since each person has different requirements for the angles of the back and legs when coaxing a child to sleep, the leg angle and back angle determined based on user data are more in line with the user's needs, so that the user's experience can be better and the user can be coaxed to sleep better during subsequent operations.

[0059] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the control module 4 is specifically used for: when performing the operation of coaxing the user to sleep, when the back bed board 111 is at the initial angle, the leg bed board 112 is at the leg angle; when the leg angle is at the initial angle, the back bed board 111 is at the back angle. Thus, it can better form a shape similar to a cradle, and then rock to coax the user to sleep.

[0060] In an optional embodiment of the present invention, the user data includes heart rate information and breathing information; the control module 4 is specifically used to determine the first speed and the second speed based on the heart rate information and breathing information.

[0061] Among them, heart rate information refers to the collected heart rate of the user, which can be monitored by a heart rate sensor. Breathing information refers to the breathing frequency of the user, which can be monitored by a breathing sensor. Since the first speed and the second speed can be adjusted according to the heart rate information and breathing information, the swinging speed can be matched with the user's heart rate and breathing, achieving the state of unity between the person and the bed, and better coaxing the user to sleep.

[0062] In some embodiments, the correlation between different heart rate information and breathing information and the first speed and the second speed can be established in advance, and the corresponding first speed and second speed can be obtained later according to the heart rate information and breathing information. For example, the first speed and second speed corresponding to different heart rate information and breathing information with better user experience can be obtained through testing, and then the heart rate information and breathing information are associated with the first speed and the second speed to form the correlation between the heart rate information and breathing information and the first speed and the second speed. The specific method of establishing the correlation between different heart rate information and breathing information and the first speed and the second speed is not specifically limited here, but is just an example.

[0063] In an optional embodiment of the present invention, Figure 1 and Figure 2As shown, the control module 4 is specifically used to: determine the user status based on user data; when the user status is sleeping or the time of entering the coaxing mode reaches a preset duration, the control and adjustment module 2 drives the angle of the leg bed board 112 and the angle of the back bed board 111 to gradually decrease to the initial angle.

[0064] Among them, the pressure sensor can monitor the user's body movement. When the user lies in bed, the pressure sensor will sense the user's tiny movements, such as turning over, adjusting posture, etc. As the user gradually enters the sleep state, the body movement will gradually decrease until it almost stops. By analyzing these body movement data through algorithms, it can be determined whether the user has fallen asleep. Heart rate is one of the important indicators reflecting the physiological state of the human body. The user's heart rate changes can be monitored by a heart rate sensor. Before and after the user falls asleep, the heart rate usually gradually decreases and tends to stabilize. By monitoring the changes in heart rate and combining body movement data, it can be more accurately determined whether the user has fallen asleep. Breathing is another important physiological parameter, which is also important for determining whether the user has fallen asleep. After the user falls asleep, breathing usually becomes more stable and regular. By analyzing the breathing data through algorithms, it can be further confirmed whether the user has fallen asleep. In some embodiments, multiple parameters such as body movement, heart rate and breathing can be comprehensively analyzed to more accurately determine whether the user has fallen asleep, that is, to determine whether the user state is a sleeping state.

[0065] When the control and adjustment module 2 drives the angle of the leg bed board 112 and the angle of the back bed board 111 to gradually decrease to the initial angle, the angle of the leg bed board 112 and the angle of the back bed board 111 can be continuously attenuated in a damping-like manner until they reach the initial angle. In this way, it is convenient for the user to enter a stable sleeping state.

[0066] In an optional embodiment of the present invention, the control module 4 is specifically used to: determine the user's height information and the user's weight information based on the user data; determine the waist angle, leg angle and back angle based on the user's height information and the user's weight information.

[0067] Among them, the user height information refers to information reflecting the user's height, and the user weight information refers to information used to reflect the user's weight. In some embodiments, the monitoring module 3 includes a pressure sensor, which senses the pressure distribution of the user lying on the bed through the pressure sensor, and then obtains the user's weight and height. The correlation between the user's height information and the user's weight information and the waist angle, leg angle and back angle can be established in advance. At this time, each user's height information and user's weight information correspond to a specific waist angle, leg angle and back angle. Later, the waist angle, leg angle and back angle can be obtained through the correlation according to the user's height information and the user's weight information. In the above manner, the waist angle, leg angle and back angle are all obtained according to the user's own height and weight, so that the obtained waist angle, leg angle and back angle can be more in line with user needs. Compared with the related art of adjusting the electric bed to a fixed angle to help the user sleep, this solution can adjust the angle of the bed board 11 according to the user data, so that the obtained angle of the bed board 11 can be more in line with user needs, solving the problem that the sleep aid is not intelligent and humanized enough.

[0068] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the regulating module 2 includes a motor 21. The control module 4 is specifically used to: determine the target motion speed of the motor 21; determine a preset PWM frequency and a preset duty cycle based on the target motion speed; and drive the motor 21 to work based on the preset PWM frequency and the preset duty cycle so that the motor 21 outputs a preset thrust.

[0069] Among them, the movement speed of the motor 21, usually referred to as the motor 21 speed, refers to the number of circles or angles that the motor 21 rotates in a unit time. The target movement speed refers to the movement speed that the control module 4 controls the motor 21 to be. Preferably, the control module 4 can control the movement speed of the motor 21 through a PLC algorithm. The preset PWM frequency refers to the PWM frequency output to the motor 21, and the preset duty cycle refers to the duty cycle output to the motor 21. The same movement speed outputs different thrusts at different duty cycles and PWM frequencies. The preset thrust refers to the thrust that the motor 21 should output. By using the PLC algorithm to control the movement speed of the motor 21, the motor 21 of the electric bed can output a constant thrust at different movement speeds.

[0070] In some embodiments, the basic control idea of ​​the motor 21 is high frequency and high duty cycle, the motor 21 operates at high speed, low frequency and low duty cycle, the motor 21 operates at low speed. In a specific embodiment, it is assumed that the electric bed motor 21 requires the following three speed levels, and each level corresponds to a constant thrust value. Therefore, through testing, the following three combinations are set to output different PWM frequencies and duty cycles at different speeds: low speed: PWM frequency = 1KHz, duty cycle = 30%; medium speed: PWM frequency = 10KHz, duty cycle = 50%; high speed: PWM frequency = 20KHz, duty cycle = 70%. That is, when the target motion speed is low speed, the preset PWM frequency is 1KHz, and the preset duty cycle is 30%; when the target motion speed is medium speed, the preset PWM frequency is 10KHz, and the preset duty cycle is 50%; when the target motion speed is high speed, the preset PWM frequency is 20KHz, and the preset duty cycle is 70%, so that the same thrust can be output at different target motion speeds.

[0071] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the control module 4 is specifically used for: obtaining the number of turns of the Hall sensor when the motor 21 is in motion; and controlling the position of the electric push rod based on the number of turns of the Hall sensor, so as to accurately control the position of the electric push rod.

[0072] In some embodiments, the adjustment module 2 further includes a motor control unit 22, and the motor control unit 22 is used to control the motor 21. The control module 4 is electrically connected to the motor control unit 22, and the motor 21 is controlled by the motor control unit 22. In some embodiments, the number of electric push rods is multiple, and correspondingly, the number of motors 21 is multiple, and the multiple motors 21 are respectively leg motors 211, back motors 212 and waist motors 213, and the leg motors 211, back motors 212 and waist motors 213 are used to adjust the angles of the leg bed board 112, the back bed board 111 and the waist bed board 113 in a one-to-one correspondence. In some embodiments, the number of leg bed boards 112 is two, namely, thigh bed boards 1121 and calf bed boards 1122, and the number of leg motors 211 is two, namely, thigh motors 2111 and calf motors 2112, and the thigh motors 2111 are used to adjust the angle of the thigh bed board 1121, and the calf motors 2112 are used to adjust the angle of the calf bed board 1122.

[0073] In some embodiments, the motor control unit 22 also automatically calibrates the position of the motor 21 each time it is reset to ensure that it can be accurately adjusted for long-term operation. For example, when the back board 111, waist board 113, and leg board 112 of the electric bed are performing a downward movement, the control part of the motor 21 is still in a downward movement state, but the working current of the motor 21 is zero and the motor 21 has no fault alarm, then the intelligent judgment is that the motor 21 has moved to the lowest position at this time, and the value of the Hall sensor is automatically calibrated to zero. Vice versa, when it reaches the highest position, it will automatically perform a full-scale calibration.

[0074] In some embodiments, Figure 1 and Figure 2 As shown, the electric bed also includes a snoring detector 5 for detecting snoring. In some embodiments, the snoring detector 5 includes one or more of an acoustic wave sensor, a MEMS sensor, and a bone conduction snoring sensor.

[0075] The control module 4 is the core part of the method, which is mainly responsible for the data processing of the sensor, the parameters and instructions set by the user, the design of the action of the electric bed motor 21 and sending it to the motor control unit 22 in steps, etc. Therefore, the control module 4 has multiple peripheral interfaces, such as the interface of the monitoring module 3 and the interface of the adjustment module 2, etc. The control module 4 and the interfaces of multiple peripherals form an intelligent control box.

[0076] In some embodiments, the smart control box also has a self-learning function. By collecting and analyzing the user's sleep data over a long period of time, it continuously optimizes and adjusts the sleep-aiding program to provide a more personalized and intelligent sleep-aiding experience. The self-learning function relies on the user control and usage data saved in the background. Based on the long-term user usage data, it summarizes the user's usage habits and preferences, and intelligently recommends sleep-aiding actions and programs to the user.

[0077] Through the above technical means, this technical solution can effectively solve the problems of existing electric beds' fixed sleep-aiding methods and movements, insufficient data processing, and inability to effectively interact with users, thereby improving users' sleep quality and user experience.

[0078] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0079] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
