Description

Technical Field

[0001] This invention relates to the field of sleep aid technology, specifically to an intelligent sound wave sleep aid and mood-soothing device. Background Technology

[0002] Sleep is an indispensable part of life for humans and other animals. It is crucial for maintaining physical and mental health. Sleep is not just simple rest, but involves complex physiological processes, including brain wave activity, hormone secretion, and body repair. With increasing life pressure, insomnia and anxiety problems are becoming more and more common, making sleep aids a necessity.

[0003] For example, a sleep aid device with sound wave hypnosis function, Chinese announcement number CN223474250U, states in its specification that "this utility model relates to the field of medical devices, and particularly to a sleep aid device with sound wave hypnosis function, including a base, a support block, a seat, a backrest, a headrest, and an electric push rod, etc. The support block is connected to the upper side of the middle of the base, the seat is connected to the upper side of the support block, the backrest is rotatably connected to the left side of the seat, the headrest is connected to the upper side of the backrest, and the electric push rod is rotatably connected to the left side of the backrest."

[0004] However, the existing devices have the following shortcomings during use: Existing devices work by moving a connecting frame and then pulling a beaded chain in the opposite direction to lower the blackout curtain. An ultrasonic sleep aid then emits sound waves to induce sleep, relaxing the brain and promoting faster sleep onset. However, the fixed installation position of the ultrasonic sleep aid means that when different users adjust the backrest angle, causing changes in headrest height, the sleep aid cannot adapt to the dynamic position of the headrest. This results in the sound waves not being accurately directed at the user's head, affecting the hypnotic effect. Furthermore, the lack of a real-time perception and feedback mechanism for the user's physiological state means it cannot determine the user's emotional state and sleep stage based on physiological signals. Consequently, the sound wave parameter adjustments lack specificity and fail to meet the user's dynamic physiological needs.

[0005] Therefore, we propose an intelligent sound wave sleep aid and mood-relieving device to address the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent sound wave sleep aid and mood-soothing device. When the user sits in an electric chair with their head resting on the headrest, after adjusting the backrest, a drive mechanism moves the movable frame to the headrest position. An infrared camera captures changes in headrest height and head contour coordinates, a heart rate sensor continuously collects heart rate variability data, and a first pressure sensor detects changes in the contact pressure between the user and the backrest. All three data points are synchronously transmitted to a PLC controller for fusion analysis. Based on the head position data, the PLC controller drives an electric telescopic rod to raise and lower the lifting seat, while simultaneously controlling a first servo motor to rotate the mounting frame around its axis. This ensures the ultrasonic sleep aid is always aligned with the head's auditory sensitive area. Based on physiological signal feedback, if the heart rate variability is low, it automatically switches to low-frequency soothing sound waves and increases their intensity; if light sleep characteristics are detected, it switches to mid-frequency sleep aid sound waves and decreases their intensity, thus solving the problems mentioned in the background art.

[0010] Preferably, the intelligent self-stop shading mechanism includes two second fixed plates fixedly connected to the top of the mobile frame, a winding shaft rotatably connected between the two second fixed plates, a shading cloth provided on the outer surface of the winding shaft, and a counterweight bar fixedly connected to one end of the shading cloth away from the winding shaft through the mobile frame.

[0011] Preferably, a second pressure sensor and two infrared proximity sensors are installed at the bottom of the counterweight bar, and a third servo motor for driving the winding shaft to rotate is fixedly installed on one side of the second fixing plate.

[0012] Preferably, the moving mechanism includes a dual-axis motor fixedly installed on the top inner side of the base. The two output ends of the dual-axis motor are fixedly connected to two one-way threaded rods. The smooth ends of the two one-way threaded rods are rotatably connected to the base, and the threads of the two one-way threaded rods are opposite in direction. Two limiting grooves are opened on the top inner side of the base. The outer surfaces of the two one-way threaded rods are threadedly connected to two moving seats, and the two moving seats are slidably connected in the two limiting grooves.

[0013] Preferably, the base is provided with a lifting plate, and the lifting plate is rotatably connected to the two movable seats with two connecting rods.

Two guide plates are slidably connected in the two guide slots, and the two guide plates are fixedly connected to the lifting plate.

[0014] Preferably, four guide rails are installed on the inner side of the movable frame, and two lifting seats are slidably connected to the outer side of the four guide rails.

[0015] Preferably, two soundproof covers are installed on one side of the two first fixed plates, and two protective covers are fixedly connected to the inner side of the movable frame.

[0016] Preferably, the base has two slides on its top and four silent wheels are installed on the bottom of the mobile frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a bio-tracking acoustic intelligent adaptation mechanism. When the user sits in the electric seat with their head resting on the headrest, after adjusting the backrest, the drive mechanism moves the movable frame to the headrest position. An infrared camera captures changes in headrest height and head contour coordinates, a heart rate sensor continuously collects heart rate variability data, and a first pressure sensor detects changes in the contact pressure between the user and the backrest. All three data points are synchronously transmitted to a PLC controller for fusion analysis. Based on the head position data, the PLC controller drives an electric telescopic rod to raise and lower the lifting seat, while simultaneously controlling a first servo motor to rotate the mounting bracket around its axis, ensuring the ultrasonic sleep aid is always aligned with the head's auditory sensitive area. Regarding physiological signal feedback, if the heart rate variability is low... If low-frequency soothing sound waves are detected, the device automatically switches to low-frequency soothing sound waves and increases their intensity. If light sleep characteristics are detected, it switches to mid-frequency sleep-aiding sound waves and decreases their intensity. This achieves dynamic matching of sound wave parameters with the user's emotional state and sleep stage, improving sleep-aiding efficiency and emotional soothing effects. It solves the problems of existing ultrasonic sleep aids where the installation position is fixed. When different users adjust the backrest angle, causing changes in the headrest height, the sleep aid cannot adapt to the dynamic position of the headrest, resulting in the sound waves not being accurately directed to the user's head, affecting the hypnotic effect. Furthermore, it lacks a real-time perception and feedback mechanism for the user's physiological state, making it impossible to judge the user's emotional state and sleep stage through physiological signals. This leads to a lack of targeted adjustment of sound wave parameters, making it difficult to adapt to the user's dynamic physiological needs.

[0018] 2. This invention features an intelligent self-stopping shading mechanism. A third servo motor drives the winding shaft to rotate and release the shading cloth. Reversing the rotation retracts the cloth, eliminating the need for manual pulling and achieving automated opening and closing of the shading curtain. Simultaneously, the servo motor's built-in power-off braking function ensures the shading cloth remains stable at any position, preventing accidental slippage or retraction. An infrared proximity sensor at the bottom of the counterweight monitors the distance to the human body in real time, forming a double protection system with a second pressure sensor. When the infrared proximity sensor detects proximity to a human body, or the second pressure sensor senses slight pressure, the signal is quickly fed back to the PLC controller. The PLC controller immediately stops the third servo motor and activates the brake, preventing the shading cloth from continuing to descend and compress the human body.

[0019] 3. This invention features a drive mechanism and a moving mechanism. In the drive mechanism, a second servo motor drives a gear to move along a rack and pinion. The moving frame slides along the base groove via a connecting frame, and with the help of silent wheels, the moving speed can be smoothly adjusted, facilitating the movement of the moving frame to the headrest position. In the moving mechanism, a dual-axis motor drives a unidirectional threaded rod to rotate. Since the threads of the two threaded rods rotate in opposite directions, the moving seat slides in the opposite direction along the limiting groove. The hinged connecting rod pushes the lifting plate to rise and fall smoothly along the guide groove. The cooperation between the guide plate and the guide groove ensures that the lifting plate has no tilting deviation. When the equipment needs to be moved, the lifting plate descends, causing the casters to extend and contact the ground. The directional function of the casters is used to achieve flexible movement. After the equipment is in place, the lifting plate rises and retracts the casters, and the base touches the ground to ensure static stability. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1 - Figure 8 As shown, the present invention provides a technical solution: an intelligent sound wave sleep aid and mood-relieving device, including a base 1, an electric seat 2 installed on the top of the base 1, a headrest 3 installed on the top of the electric seat 2, a movable frame 4 set on the top of the base 1, a driving mechanism 5 for driving the movable frame 4 to move on one side of the base 1, a sound wave intelligent adaptation mechanism 6 for tracking position on the inner side of the movable frame 4, an intelligent self-stop light-blocking mechanism 7 set on the top of the movable frame 4, a moving mechanism 8 set on the inner side of the base 1, and a PLC controller 9 installed on one side of the movable frame 4, with the wiring terminals of the PLC controller 9 connected to the device wiring harness; The sound wave intelligent adaptation mechanism 6 for tracking and positioning includes two electric telescopic rods 601 fixedly installed on the top of the mobile frame 4. The telescopic ends of the two electric telescopic rods 601 extend through the mobile frame 4 and are fixedly connected to two lifting seats 602. Four first fixing plates 603 are fixedly connected to one side of the two lifting seats 602. Two rotating shafts 604 are rotatably connected between the four first fixing plates 603. Two mounting brackets 605 are fixedly sleeved on the outer surface of the two rotating shafts 604. Two ultrasonic sleep aids 606 are installed on one side of the two mounting brackets 605. Two first servo motors 607 for driving the rotation of the two rotating shafts 604 are fixedly installed on one side of the two first fixing plates 603. A bracket 608 is fixedly connected to the electric seat 2. An infrared camera 609 is installed on the top inner side of the bracket 608. A heart rate sensor 610 is embedded inside the headrest 3. Two first pressure sensors 611 are embedded inside the electric seat 2.

[0024] like Figure 1 and Figure 4 As shown, the drive mechanism 5 includes two grooves 501 on both sides of the base 1. Two connecting brackets 502 are slidably connected in the two grooves 501, and the two connecting brackets 502 are fixedly connected to both sides of the movable frame 4. The grooves 501 on both sides of the base 1 and the connecting brackets 502 on both sides of the movable frame 4 form a sliding guide cooperation, which can accurately limit the movement trajectory of the movable frame 4, avoid lateral deviation or shaking during movement, and ensure that the movable frame 4 always moves smoothly along the headrest 3.

[0025] like Figure 4 and Figure 5 As shown, a second servo motor 503 is fixedly installed on one side of one of the connecting frames 502. The output end of the second servo motor 503 movably passes through one of the connecting frames 502 and is fixedly connected to a gear 504. A rack 505 is fixedly connected to one side of the base 1. The gear 504 and the rack 505 mesh with each other. The servo motor can achieve precise closed-loop control of speed and displacement. With the rigid meshing of the gear 504 and the rack 505, the moving speed of the moving frame 4 can be kept stable and controllable, and the stopping position can be accurate. The ultrasonic sleep aid 606 can be quickly moved to the corresponding area of ​​the headrest 3. Moreover, the meshing transmission structure has high transmission efficiency, low wear, and strong stability. It is not easy to have transmission failure after long-term use, thus reducing equipment maintenance costs.

[0026] like Figure 1 , Figure 4 and Figure 5As shown, the intelligent self-stop shading mechanism 7 includes two second fixed plates 701 fixedly connected to the top of the mobile frame 4. A winding shaft 702 is rotatably connected between the two second fixed plates 701. A shading cloth 703 is provided on the outer surface of the winding shaft 702. The end of the shading cloth 703 away from the winding shaft 702 passes through the mobile frame 4 and is fixedly connected to a counterweight 704. The second fixed plates 701 provide stable support for the winding shaft 702, ensuring that the winding shaft 702 rotates without deviation, thus achieving smooth winding and unwinding of the shading cloth 703. The counterweight 704 can use its own weight to pull the shading cloth 703 vertically downward, preventing wrinkles and tangles from appearing during the unwinding process, ensuring uniform shading effect. There is no need to manually pull the shading cloth 703, realizing the automation of shading operation and improving the ease of use of the equipment. At the same time, the setting of the counterweight 704 ensures that the shading cloth 703 is subjected to balanced force during winding and unwinding, extending the service life of the shading cloth 703.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, a second pressure sensor 705 and two infrared proximity sensors 706 are installed at the bottom of the counterweight 704. A third servo motor 707 for driving the winding shaft 702 is fixedly installed on one side of one of the second fixing plates 701. The second pressure sensor 705 and the infrared proximity sensors 706 at the bottom of the counterweight 704 form a double safety protection, which can monitor the distance and contact status between the light-blocking cloth 703 and the human body in real time during the lowering process. Once it detects that the light-blocking cloth is close to or touches the human body, it can quickly feed back a signal to the PLC controller 9, triggering the stop brake of the third servo motor 707, completely avoiding the safety hazards caused by the light-blocking cloth 703 pressing on the human body. The third servo motor 707 drives the winding shaft 702, which can accurately control the winding speed and stroke of the light-blocking cloth 703. With the help of the sensors, it can realize automatic winding and intelligent self-stop, improve the convenience of operation, and ensure the safety of use. At the same time, the power-off braking function of the servo motor ensures that the light-blocking cloth 703 stays stably at any position and avoids accidental slippage.

[0028] like Figure 2 and Figure 7As shown, the moving mechanism 8 includes a dual-axis motor 801 fixedly installed on the top inner side of the base 1. Two one-way threaded rods 802 are fixedly connected to the two output ends of the dual-axis motor 801. The smooth ends of the two one-way threaded rods 802 are rotatably connected to the base 1, and the threads of the two one-way threaded rods 802 rotate in opposite directions. Two limiting grooves 803 are formed on the top inner side of the base 1. Two movable seats 804 are threadedly connected to the outer surfaces of the two one-way threaded rods 802, and the two movable seats 804 are slidably connected within the two limiting grooves 803. The dual-axis motor 801 can synchronously drive the two one-way threaded rods 802 to rotate, ensuring consistent power output on both sides. The opposite rotation of the threads of the two one-way threaded rods 802 enables the two movable seats 804 to slide synchronously in opposite directions along the limiting grooves 803, resulting in strong transmission synchronization and providing a foundation for the smooth lifting of the subsequent lifting plate 805. The limiting grooves 803 guide and limit the movable seats 804, preventing deviation or jamming during sliding and ensuring stable and reliable transmission.

[0029] like Figure 2 and Figure 7 As shown, a lifting plate 805 is installed inside the base 1. Two connecting rods 806 are rotatably connected between the lifting plate 805 and the two movable seats 804. Four universal wheels 807 are installed on the bottom of the lifting plate 805. Two through slots 808 are opened on the bottom of the base 1, and two guide slots 809 are opened on the inner side of the base 1. Two guide plates 810 are slidably connected in the two guide slots 809, and the two guide plates 810 are fixedly connected to the lifting plate 805. The linear motion of the movable seats 804 is converted into the vertical lifting motion of the lifting plate 805 through the connecting rods 806. High efficiency is achieved by quickly extending and retracting the casters 807. When the equipment moves, the casters 807 extend through the through groove 808 to contact the ground, and the steering function of the casters 807 enables flexible movement of the equipment, reducing the difficulty of handling. When stationary, the casters 807 retract, and the base 1 touches the ground to ensure the stability of the equipment and prevent shaking during use. The sliding cooperation between the guide groove 809 and the guide plate 810 can limit the lifting trajectory of the lifting plate 805, ensuring that the lifting plate 805 lifts vertically without tilting, avoiding damage caused by uneven force on the casters 807, and extending the service life of the mechanism.

[0030] like Figure 5 and Figure 6As shown, four guide rails 612 are installed on the inner side of the movable frame 4, and two lifting seats 602 are slidably connected to the outer side of the four guide rails 612. Additionally, two arc-shaped grooves 613 are formed on one side of the two first fixing plates 603, and two limiting rods 614 are fixedly connected to one side of the two mounting brackets 605, with the two limiting rods 614 slidably connected within the two arc-shaped grooves 613. The four guide rails 612 on the inner side of the movable frame 4 provide precise guidance for the lifting seats 602, ensuring that the lifting seats 602 rise and fall vertically along the guide rails 612, and preventing the lifting process from being disrupted. The movement of the ultrasonic sleep aid 606 is designed to ensure its precise lifting accuracy, allowing it to accurately target the head's auditory sensitive area. The sliding fit between the arc-shaped groove 613 and the limiting rod 614 limits the rotation angle of the mounting bracket 605, preventing excessive rotation of the mounting bracket 605 when driven by the first servo motor 607, which could cause the sound waves to deviate from the target area. At the same time, it reduces the torque load on the rotating shaft 604, protecting the rotating shaft 604 and the first servo motor 607. The sliding fit reduces frictional resistance, making the lifting seat 602 and the mounting bracket 605 move more smoothly.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, two soundproof covers 615 are installed on one side of the two first fixed plates 603, and two protective covers 616 are fixedly connected to the inside of the movable frame 4. The soundproof covers 615 can effectively block the noise generated when the motor is working, so as to avoid noise interference with the user's mood and sleep. The protective covers 616 can form physical protection for the components of the sound wave intelligent adaptation mechanism 6, so as to avoid the user accidentally touching the moving parts and causing safety hazards.

[0032] like Figure 1 and Figure 3 As shown, the top of the base 1 has two slide rails 10, and the bottom of the mobile frame 4 is equipped with four silent wheels 11. The two slide rails 10 on the top of the base 1 provide guidance for the silent wheels 11 at the bottom of the mobile frame 4, which slide in conjunction with the connecting frame 502 of the drive mechanism 5, further improving the stability of the mobile frame 4 and preventing shaking or deviation during movement. The silent wheels 11 adopt a low-noise rolling design, which can reduce the friction noise when the mobile frame 4 moves, creating a quiet usage environment.

[0033] The usage and working principle of this device are as follows: During the equipment movement and positioning stage, the moving mechanism 8 is started, and the dual-axis motor 801 drives the two one-way threaded rods 802 to rotate. The two one-way threaded rods 802 drive the two moving seats 804 to slide in the opposite direction. Through the connecting rod 806, the lifting plate 805 is pushed down, so that the casters 807 pass through the through groove 808 and contact the ground. After the equipment is pushed to the target position, the dual-axis motor 801 is started in the opposite direction to retract the casters 807, and the base 1 touches the ground and remains stable. During the user seating adjustment phase, the user sits on the electric seat 2 with their head resting on the headrest 3 and their back against the backrest of the electric seat 2. They can adjust the backrest angle as needed using the adjustment buttons on the side of the electric seat 2 to achieve a comfortable posture. The user then slowly rests their head on the middle of the headrest 3, ensuring that the headrest 3 is fully in contact with the back of the head and neck. At this time, the heart rate sensor 610 inside the headrest 3 needs to be in indirect contact with the skin to ensure accurate collection of physiological signals. During the frame movement phase, the drive mechanism 5 is activated, the second servo motor 503 starts, and drives the gear 504 to rotate along the rack 505. The moving frame 4 slides along the groove 501 of the base 1 through the connecting frames 502 on both sides. The bottom silent wheel 11 rolls along the slide 10 to assist in the rolling. The moving frame 4 moves towards the headrest 3 until the ultrasonic sleep aid 606 is aligned with both sides of the headrest 3. At this time, the PLC controller 9 receives the position feedback signal from the infrared camera 609 and controls the second servo motor 503 to stop rotating. During the shading phase, the third servo motor 707 is started, driving the take-up shaft 702 to rotate. The shading cloth 703 is slowly lowered vertically under the gravity pull of the counterweight 704, gradually blocking the light in front of the moving frame 4. During the lowering process of the shading cloth 703, the infrared proximity sensor 706 at the bottom of the counterweight 704 monitors the distance to the human body in real time, and the second pressure sensor 705 senses the touch pressure. If any sensor detects an abnormal signal, it immediately feeds back to the PLC controller 9, triggering the stop brake of the third servo motor 707 to prevent the shading cloth 703 from pressing on the human body. In the closed-loop position tracking stage, the infrared camera 609 on the bracket 608 can capture the change in the height of the headrest 3 and the head contour coordinates according to the backrest angle of different users. The data is transmitted to the PLC controller 9. The PLC controller 9 drives the electric telescopic rod 601 to extend and retract according to the position data, which drives the lifting seat 602 to rise and fall vertically along the guide rail 612. At the same time, it controls the first servo motor 607 to drive the rotating shaft 604 to rotate, and the mounting bracket 605 rotates accordingly. The limiting rod 614 slides and limits along the arc groove 613, so that the ultrasonic sleep aid 606 is always aligned with the head's auditory sensitive area. During the physiological adaptation closed-loop stage, the heart rate sensor 610 inside the headrest 3 continuously collects heart rate variability data, and the first pressure sensor 611 inside the electric seat 2 detects changes in the contact pressure between the human body and the backrest (during deep sleep, the posture is stable and the pressure signal is stable; during light sleep, the posture is easily changed and the pressure signal fluctuates). The data from both are transmitted synchronously to the PLC controller 9. The PLC controller 9 integrates and analyzes the data to determine the user's emotional state and sleep stage. If the heart rate variability is low (emotional anxiety), the ultrasonic sleep aid 606 is automatically switched to low-frequency soothing sound waves and the intensity is increased. If light sleep characteristics are detected, the sound waves are switched to medium-frequency sleep aid sounds and the intensity is reduced. If the heart rate variability is high (emotional relaxation), the sound waves are maintained at a gentle low frequency and the intensity is further reduced. If deep sleep characteristics are detected, the ultrasonic sleep aid 606 is directly turned off, and the seat and light-blocking status are locked to avoid interference. The entire process is a dynamic closed-loop adaptation.
