Description

Technical Field

[0001] This invention relates to the field of infant and toddler products technology, and in particular to an intelligent silent rocker based on multi-belt drive. Background Technology

[0002] With the development of technology and the improvement of parenting concepts, the market for smart infant and toddler products is growing rapidly. Traditional baby rockers mostly use manual rocking or simple motor-driven methods, which have the following drawbacks:

[0003] 1. High Noise Levels: Traditional rockers often use a single motor with gears or crank-connecting rod mechanisms to achieve rocking. During operation, the motor's rotation and the friction and collision between mechanical parts generate significant noise. This noise not only easily disturbs sleeping infants and affects their sleep quality, but prolonged exposure to a noisy environment may also adversely affect their hearing development. For example, some rockers using old motors and simple gear drives can reach noise levels exceeding 50 decibels, far exceeding the standard for a quiet environment suitable for infant sleep. Furthermore, the crank-connecting rod mechanism is prone to impact and vibration during reversal, resulting in unstable rocking and poor comfort.

[0004] 2. Shock absorption and stability issues: When the shaker is in motion, hard collisions can easily occur between the frame and the base, generating noise and discomfort; although some products use shock-absorbing pads, the effect is limited and cannot effectively filter the impact caused by the motor starting, stopping and reversing.

[0005] 3. Limited Functionality: Traditional rocking cribs are limited to mechanical rocking, lacking interactive and remote monitoring capabilities for infants. Parents cannot monitor their baby's sleep status in real time. When unexpected situations arise, such as spitting up or getting stuck while the baby is sleeping, parents may struggle to detect and address them promptly, posing safety risks. This keeps parents constantly on edge while the baby sleeps, restricting their freedom of movement.

[0006] 4. Inconvenient Control: When using traditional rocking cribs, parents often need to walk to the crib to manually adjust parameters such as rocking speed and amplitude. If the baby suddenly wakes up at night and needs soothing, parents need to get up and walk to the crib to operate it, which not only affects their rest but may also cause the baby to cry more intensely due to the time wasted. Furthermore, traditional rocking cribs cannot be remotely controlled, making it difficult for parents to adjust the crib according to the baby's needs while they are busy in other rooms.

[0007] In conclusion, traditional rocking beds have many shortcomings in terms of noise control, functional versatility, ease of operation, and infant sleep monitoring, failing to meet the high-quality infant care needs of modern families. Therefore, developing a new type of rocking bed that is quiet, feature-rich, intelligently controllable, and equipped with intelligent monitoring capabilities is of significant practical importance. Summary of the Invention

[0008] The purpose of this invention is to provide an intelligent silent rocking bed that is stable in operation, low in noise, highly comfortable, easy to operate, and highly safe.

[0020] Furthermore, the support frame includes a top fixed bracket, a bottom fixed bracket, a vertical fixed bracket, and a horizontal fixed bracket. The multi-belt series rotation system is embedded inside the support frame. The bottom of the bed is mounted on the upper surface of the top fixed bracket. The axle of the driven belt pulley in the last linkage of the multi-belt series rotation system is connected to a connecting rod to drive the connecting rod to reciprocate in the vertical direction. The other end of the connecting rod is connected and fixed to the top fixed bracket.

[0021] Furthermore, the spring-supported shock absorption system is located within the support frame and includes multiple springs, one end of which is fixedly connected to the bottom fixed bracket and the other end of which is fixedly connected to the top fixed bracket.

[0022] Furthermore, the intelligent control system includes:

[0023] A camera module is located on the upper edge of the bed and is electrically connected to the central processing unit to collect video information inside the bed.

[0024] A wireless communication module, electrically connected to the central processing unit, is used to establish a communication connection with an external mobile terminal; the external mobile terminal obtains the video information through the wireless communication module.

[0025] Furthermore, the intelligent control system also includes an audio module, which is electrically connected to the central processing unit to receive and play audio signals to enable two-way voice communication and / or music playback functions.

[0026] Furthermore, the intelligent control system also includes an environmental sensing module, which includes a motion sensor and a motion-sensing night light; the motion sensor is used to detect moving objects in the surrounding environment, and the central processing unit is configured to control the activation and deactivation of the motion-sensing night light based on the signal from the motion sensor.

[0027] Furthermore, the central processing unit is further configured as follows:

[0028] The wireless communication module receives control commands from the external mobile terminal.

[0029] In response to the control command, the corresponding execution component is controlled to operate.

[0030] Furthermore, the control commands include at least one of the following: a speed control command for adjusting the rotational speed of the transmission motor, a monitoring command for turning the camera module on or off, and an audio command for controlling voice dialogue or audio playback.

[0031] The response to the control command to control the corresponding execution component's action includes:

[0033] In response to the monitoring command, the image acquisition function of the camera module is turned on or off;

[0034] In response to the audio command, control the audio module to enable or disable two-way voice intercom and / or music playback functions.

[0035] Furthermore, the central processing unit is further configured as follows:

[0036] When the camera module detects movement within the bed that exceeds a preset threshold, a reminder message is sent to an external mobile terminal via the wireless communication module.

[0037] Furthermore, the central processing unit is also configured to run a preset rocking mode, which is associated with a set of predefined control parameters for the drive motor. The central processing unit automatically controls the reciprocating motion of the bed according to the selected rocking mode.

[0038] The core of this invention's intelligent silent rocker based on multi-belt drive lies in three systems collaboratively controlled by a central processing unit: 1. Multi-belt series rotation system: Driven by a single motor, multiple driven pulleys are connected in series via belts, driving the bed's vertical movement in a "load-sharing and relay transmission" manner, fundamentally reducing operating noise and vibration. 2.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 merely illustrative and not intended to limit the invention.

[0043] It should be noted that references to "an embodiment," "embodiment," "example embodiment," etc., in this specification refer to the described embodiment including specific features, structures, or characteristics, but not every embodiment must include these specific features, structures, or characteristics. Furthermore, such expressions do not refer to the same embodiment.

[0044] Sleep quality is crucial for a baby's physical and brain development. However, infants often require frequent soothing from parents, especially rocking them to sleep, which consumes a significant amount of time and energy. To address this, this invention presents a smart, silent rocking crib based on a multi-belt drive system. It aims to provide a comfortable sleep environment for infants while offering parents a convenient parenting method, allowing them to care for their babies more easily, both at night and during daily activities, enabling them to better accompany their babies' growth.

[0045] Figures 1-3 This invention illustrates an intelligent silent shaking bed based on multi-belt drive, comprising a bed frame, a support frame, a multi-belt series rotation system 11, a spring support and shock absorption system, an intelligent control system, and a central processing unit 3, wherein:

[0046] The bed frame is used to carry the infant; the support frame is used to support the bed frame; the multi-belt series rotation system 11 is installed on the support frame, including a drive motor 17, a drive pulley 18 driven by the drive motor 17, at least two driven pulleys 19, and a drive belt 20 connecting the drive and driven pulleys, and the axle of the last driven pulley 19 is connected to the bed frame for driving the bed frame to reciprocate vertically relative to the support frame; the spring support shock absorption system is installed on the support frame to buffer the impact generated when the bed frame moves; the intelligent control system is used to monitor the infant's status and control the operation of the rocker; the central processing unit 3 is connected to the multi-belt series rotation system 11, the spring support shock absorption system, and the intelligent control system;

[0047] The central processing unit is configured to: control the start, stop, speed and direction of the transmission motor 17 to adjust the reciprocating speed and frequency of the bed; receive and process sensor data and user instructions from the intelligent control system; and coordinate the operation of the multi-belt series rotation system 11, the spring support shock absorption system and the intelligent control system according to the user instructions or preset program.

[0048] Specifically, the support frame includes a top fixed bracket 15, a bottom fixed bracket 24, a vertical fixed bracket 22, and a horizontal fixed bracket 23. A multi-belt series rotation system 11 is embedded inside the support frame. The bottom of the bed is mounted on the upper surface of the top fixed bracket 15. The axle of the driven belt pulley 19 of the multi-belt series rotation system 11 is connected to a connecting rod 21 to drive the connecting rod 21 to reciprocate in the vertical direction. The other end of the connecting rod 21 is connected and fixed to the top fixed bracket 15. The bed specifically includes a rocking bed guardrail and a first bed board 7, a second bed board 8, and a bed base 9 stacked in sequence. The bed base 9 is installed on a top fixed bracket 15. The bed also includes front and rear decorative baffles 10 and left and right decorative baffles 12. The bottom of the support frame is also provided with a rocking bed base baffle 13 and rocking bed support feet 14 installed on the rocking bed base baffle 13. In this embodiment, the power output by the transmission motor passes through the driving pulley 18, each driven pulley 19, the connecting rod 21, and the top fixed bracket 15 in sequence, so that the top fixed bracket 15 can reciprocate in the vertical direction, and the bed moves back and forth in the vertical direction with the top fixed bracket 15.

[0049] As shown in the figure, this embodiment includes two driven pulleys 19. The power output from the transmission motor 17 is transmitted to the driving pulley 18. The driving pulley 18 drives the first driven pulley 19 to rotate synchronously via the transmission belt 20. The first driven pulley 19 drives the second driven pulley 19 to rotate via the transmission belt 20. Of course, in other examples, the number of driven pulleys 19 can be set according to needs. Multiple driven pulleys 19 are connected in series via belts. The rotation of the first driven pulley 19 will drive the next driven pulley 19, and so on, to achieve synchronous rotation of multiple pulleys. The rocker body is connected to the shaft of the last driven pulley 19. As the pulley rotates, it drives the rocker to move vertically up and down. Power is transmitted through the friction between the belt and the pulley. The multi-belt series design can effectively distribute the power, making the rocker's movement smoother, while also reducing the load on individual belts and pulleys and extending their service life. Moreover, by adjusting the motor speed and the diameter ratio of the pulleys, the speed and frequency of the rocker's up and down movement can be precisely controlled to meet the different sleep needs of infants.

[0050] Compared to traditional gear drives or direct motor drives, the multi-belt series drive system 11 used in this embodiment has better noise reduction. During belt drive, the contact between the belt and pulleys is relatively gentle, reducing rigid collisions and friction between mechanical parts, thus significantly reducing noise generated during operation. Experimental data shows that under the same operating conditions, the noise generated by the multi-belt series drive system is about 15-20 decibels lower than that of traditional gear drives, creating a quiet and comfortable sleeping environment for infants. Furthermore, the essence of the multi-belt series drive system lies in "load sharing and relay transmission." In this series system, the weight of the load is evenly distributed across multiple driven pulleys, with each driven pulley only needing to bear the weight of the small section of belt and load directly above it. The motor does not need to overcome the static friction of the entire load on the conveyor belt at once. For any driven pulley in the system, the resistance it needs to overcome to rotate (bearing friction and the friction of the small portion of the load it carries) is very small relative to the total load of the entire system. Because the load is distributed, the system's total "equivalent frictional resistance" is much smaller than the frictional force when all the loads are concentrated in one place. Therefore, the motor does not require enormous torque to start and maintain the entire system, thus reducing the requirements for motor power, torque, and size. This significantly extends the service life and lowers the cost of meeting specific motor specifications. Furthermore, this structure is relatively simple to install and maintain. Replacement of the belt is convenient when it wears or is damaged after long-term use, reducing user costs and maintenance difficulty.

[0051] The spring-supported shock absorption system of this embodiment is located within the support frame and includes four springs 16. One end of each spring 16 is fixedly connected to the bottom fixed bracket 24, and the other end is fixedly connected to the top fixed bracket 15. Specifically, a spring 16 is installed at each of the four corners of the top fixed bracket 15. When the rocker moves vertically up and down under the drive of the multi-belt series rotation system 11, it inevitably experiences a certain impact force with the ground or the surface it is placed on. The spring shock absorption design utilizes the elastic characteristics of the springs 16 to reduce the impact of this impact force on the rocker and the baby. When the rocker moves downward and contacts the ground or the surface it is placed on, the springs 16 are compressed, increasing their elastic potential energy. This converts the downward kinetic energy of the rocker into the elastic potential energy of the springs, thereby buffering the downward impact force of the rocker. When the rocker moves upward, the springs release their elastic potential energy to assist the rocker in moving upward, while reducing the vibration caused by inertia during the upward movement. In this way, the springs 16 can effectively reduce the impact and vibration generated during the rocker's movement, making the rocker's movement smoother and gentler.

[0052] This spring-dampening design provides a more comfortable sleep experience for infants. Experiments show that in rockers equipped with spring damping devices, the amplitude of vibration felt by the infant during operation is reduced by approximately 30%-40% compared to rockers without springs. Infants are not disturbed by the rocker's vibrations during sleep, which helps improve sleep quality and promotes healthy growth. At the same time, the presence of springs also reduces damage to the surface on which the rocker rests, extending the lifespan of both the rocker and the surface.

[0053] The intelligent control system includes a camera module 2 and a wireless communication module. The camera module 2 is located on the upper edge of the bed, specifically on the upper edge of the rocker bed guardrail 5 and is encapsulated and fixed by the swing arm bottom shell 1 and the swing arm front shell 4. It is electrically connected to the central processing unit 3 to collect video information inside the bed. The central processing unit 3 is the MCU unit on the main control PCBA. The wireless communication module is electrically connected to the central processing unit to establish a communication connection with an external mobile terminal. The external mobile terminal can obtain the video information through the wireless communication module, and can also interact with command information through the wireless communication module.

[0054] Camera module 2 features high-definition shooting and night vision capabilities, enabling real-time monitoring of the baby's sleeping status inside the bed.

[0055] Specifically, camera module 2 connects wirelessly to an external mobile terminal (such as a mobile app), transmitting the captured video footage in real time to the parent's mobile phone (which is linked to camera module 2 via a designated app). This allows parents to check on their baby's sleep in the cradle from anywhere in the house, even when away from home, as long as their phone is connected to the internet. Preferably, camera module 2 also supports multi-angle adjustment, allowing parents to remotely control the camera's angle via the app for comprehensive monitoring of the baby. If the baby experiences sudden situations such as spitting up or getting stuck while sleeping, parents can promptly detect these issues through the camera and take immediate action to ensure the baby's safety. For example, even in dimly lit rooms at night, the camera's night vision function can clearly capture the baby's image, providing peace of mind for parents.

[0056] The central processing unit is also configured to send a reminder message to an external mobile terminal via the wireless communication module when the camera module 2 detects movement within the bed exceeding a preset threshold. For example, the camera may also have motion detection capabilities; when it detects significant movement in the infant, it will automatically send a reminder to the parent's mobile app, allowing the parent to monitor the infant's movements promptly.

[0057] Furthermore, the intelligent control system also includes an audio module and an environmental sensing module. The audio module is electrically connected to the central processing unit 3 to receive and play audio signals, enabling two-way voice communication and / or music playback. Specifically, the audio module includes a microphone and a speaker, which can be integrated into the camera module 2 to enable two-way voice communication between parents and infants, and can also play pre-stored soothing music or white noise. The environmental sensing module includes a motion sensor and a motion-sensing night light 6. The motion sensor is used to detect moving objects in the surrounding environment, and the central processing unit 3 is configured to control the activation and deactivation of the motion-sensing night light 6 based on the signals from the motion sensor. For example, a set of motion-sensing night lights can be installed on four support columns on the side of the rocker's main frame. The lights use diffused soft lighting effects and will automatically turn on when a person or moving object approaches, and will automatically turn off after one minute when no person or moving object is detected. Parents can also remotely control the lights via an app.

[0058] The central processing unit 3 is further configured to: receive control commands from the external mobile terminal via a wireless communication module; and, in response to the control commands, control the corresponding actuators to perform actions. The control commands include at least one of a speed control command for adjusting the rotational speed of the drive motor 17, a monitoring command for turning the camera module 2 on or off, and an audio command for controlling voice dialogue or audio playback. The action of controlling the corresponding actuators in response to the control commands includes: adjusting the operating parameters of the drive motor in response to the speed control command to change its rotational speed and frequency; turning the image acquisition function of the camera module on or off in response to the monitoring command; and controlling the audio module to turn on or off its two-way voice intercom and / or music playback functions in response to the audio command.

[0059] The central processing unit 3 is also configured to run a preset rocking mode, which is associated with a set of predefined control parameters of the drive motor. The central processing unit 3 automatically controls the reciprocating motion of the bed according to the selected rocking mode.

[0060] In practice, parents install a designated APP on their mobile phone, tablet, or personal computer and bind it to the device. Then, a wireless communication connection is established between the APP and the wireless communication module (such as a Bluetooth-based wireless connection, a wireless LAN connection, or an internet connection broadcast by a router; in this embodiment, the wireless communication module is preferably a WiFi module, meaning the communication connection between the mobile APP and the central processing unit is an internet connection broadcast by a router). In this way, parents can easily control the speed and frequency of the rocking crib through the APP, and can also perform remote control functions such as monitoring, intercom, and music playback.

[0061] Specifically, the app interface features speed and frequency adjustment sliders or buttons, allowing parents to easily adjust the rocking speed and frequency of the cradle by touching the phone screen, based on the baby's needs and state. The app communicates with the cradle's control system via Wi-Fi or Bluetooth, transmitting the parent's commands from the app to the cradle's control module. The control module then adjusts the motor speed accordingly, achieving precise control over the cradle's speed and frequency. For example, when the baby is about to fall asleep, parents can slow down the cradle and reduce the frequency to create a quiet and soothing sleep environment; when the baby is crying and needs comforting, the speed and frequency can be increased to provide the baby with a greater sense of security. Parents can also set up automatic scene matching modes through the app to automatically adjust the cradle's speed and frequency, such as "deep sleep" and "soothing sleep" modes, automatically matching different rocking speeds and frequencies.

[0062] The app can also receive real-time video feeds from camera module 2, enabling monitoring of the baby's sleep. It allows real-time viewing of the camera feed, supports video recording and photo taking, and features an intercom function. Parents can speak on their phones, and the sound will be played back through the speaker in the rocker's camera, allowing parents to interact with and soothe their baby even when they are not physically present. For example, if a parent sees the baby waking and crying while cooking in the kitchen, they can use the intercom function to gently soothe the baby, making the baby feel their presence. Furthermore, the app can record rocker usage data, such as rocking time, speed, and frequency, helping parents understand the baby's sleep habits and patterns, providing a reference for better baby care.

[0063] Compared with the prior art, the intelligent silent shaking bed based on multi-belt drive provided by the present invention has the following beneficial effects:

[0064] I. Significant Quiet Operation Advantage: The multi-belt series rotation method of the silent intelligent rocker described in this invention fundamentally reduces rigid friction and collisions between mechanical parts. Compared with the direct motor drive or gear transmission commonly found in traditional rockers, it greatly reduces operating noise. Professional testing shows that under normal operating conditions, the noise generated by this rocker can be controlled below 30 decibels, almost approaching the ambient background noise level, creating an extremely quiet sleep environment for infants and effectively avoiding the adverse effects of noise on infant sleep quality and hearing development. Simultaneously, the springs installed at the four corners of the rocker frame further reduce noise and vibration generated by impacts with the ground or placement surface during rocker movement. In actual use, even if the rocker runs for a long time, the noise it generates will not disturb a sleeping infant. Parents do not need to worry about noise affecting the infant's rest, truly providing a quiet and comfortable sleep space for the baby.

[0065] II. Smart and Convenient Control: Parents can easily remotely control the rocking crib via a mobile app. Whether busy in the living room, cooking in the kitchen, or resting in the bedroom, parents can adjust the speed and frequency of the rocking crib according to the baby's condition, as long as they have their phone. For example, if a parent notices the baby crying in the rocking crib while watching TV in the living room, they can immediately increase the rocking speed via the app to soothe the baby. This remote control function greatly improves the convenience of caring for the baby, saving parents time and energy, and eliminating the need to frequently get up to operate the crib. Moreover, the app's monitoring function allows parents to understand the baby's sleep status at any time. Even when not physically present, parents can clearly see the baby's every move through their phone screen. For example, when parents are out running errands, they can check via the app to see if the baby is sleeping soundly and if any abnormalities have occurred, truly enabling them to monitor the baby's sleep safety anytime, anywhere. In addition, the app's intercom function allows parents to interact with the baby, soothing the baby with their voice even from a distance, making the baby feel the parent's presence.

[0066] III. Comfort and Safety Guaranteed: The multi-belt series rotation mechanism of the rocker ensures smooth and gentle movement, further reduced by spring shock absorption. Infants sleeping in this rocker experience a gentle and comfortable swaying, similar to being in their mother's arms, which helps improve sleep quality and promotes healthy growth. From a safety perspective, the rocker's robust structure, with its frame and body made of durable materials, can withstand various movements and forces exerted by the infant during sleep. A camera mounted on the upper bracket monitors the infant's sleep in real time. Parents can promptly detect and address any dangerous situations such as spitting up or getting stuck while rolling over, effectively ensuring the infant's sleep safety. The app's motion detection alert function also allows parents to be aware of their infant's movements immediately, preventing accidents and providing comprehensive protection for the infant's sleep safety.

[0067] In summary, the core of the intelligent silent rocker based on multi-belt drive provided by this invention lies in three major systems collaboratively controlled by a central processing unit: 1. Multi-belt series rotation system: Driven by a single motor, multiple driven pulleys are connected in series via belts to drive the vertical movement of the bed in a "load-sharing and relay transmission" manner, fundamentally reducing operating noise and vibration. 2. Spring support shock absorption system: Springs are installed at key locations in the support frame to effectively absorb and buffer the impact of movement. 3. Intelligent control system: Integrates a camera, audio, and wireless communication modules, and is equipped with a mobile APP, enabling parents to remotely monitor the baby, conduct two-way voice communication, and precisely control the speed and frequency of the rocker. Thus, this invention achieves extremely quiet operation, providing the baby with a stable and comfortable sleep experience; its intelligent control function allows parents to operate remotely and monitor in real time, significantly improving childcare convenience and infant sleep safety.
