Description

Technical Field

[0001] This invention relates to the field of children's exercise technology, and in particular to a gamified obesity management system and reward mechanism for children. Background Technology

[0002] Childhood obesity has become a significant health problem in today's society. It not only affects children's physical development and increases the risk of chronic diseases such as cardiovascular disease and diabetes, but it can also negatively impact their mental health, causing damage to self-esteem and social difficulties. The root causes of childhood obesity often lie in unhealthy eating habits, such as excessive consumption of high-sugar, high-fat fast food and snacks, and a lack of sufficient physical exercise. Therefore, families, schools, and society should work together to create a healthier living environment for children by promoting balanced diets, increasing physical activity time, and reducing screen time, helping them establish good habits, avoid obesity, and grow up healthily.

[0003] Chinese patent CN210447952U discloses a safe training device for children's physical fitness exercise. It uses a spring to realize energy conversion, so that the kinetic energy provided by the muscles and the elastic potential energy of the spring are continuously converted, thereby exercising muscle strength and endurance, and thus enhancing the user's physical fitness. The device is reasonably designed and easy to use. When children exercise, they only need to push the button and step on the pedal. The operation is safe, with a low rate of child misoperation, a high safety factor, and good reliability. The device is equipped with an adjustable seat, which can be set to the optimal height according to the height of the user to meet the needs of different groups of people.

[0004] However, the above technical solutions still have significant technical defects: due to the elastic deformation of the spring during long-term stepping, the potential energy decreases. As children grow, the above training devices cannot meet the training needs well and have poor applicability, which is not conducive to children's long-term physical exercise. Summary of the Invention

[0005] The main objective of this invention is to overcome the shortcomings of existing training devices, which cannot adequately meet the needs of growth training and have poor applicability, thus hindering children's long-term endurance and physical fitness training. This invention provides a gamified obesity management system and reward mechanism for children. This system and reward mechanism can conduct endurance training on multiple parts of the child's body, and uses a scoring system for each endurance training session to motivate children's interest in endurance training, promoting their healthy growth. It can be adjusted according to the child's increasing endurance and strength, making it convenient for children to use at different stages of training and highly applicable.

[0006] The technical solution adopted by this invention to achieve its technical objective is: a gamified obesity management system and reward mechanism for children, including a tablet. Card sleeves are fixedly installed at both ends of the tablet, and a counterweight is fixedly connected to one end. An operating platform is fixedly installed above the counterweight via a support frame. A handle is fixedly connected to one side of the support frame. A first camera is fixedly installed above the operating platform, and a second camera is fixedly installed below it. The first camera is used to collect the child's identity information, and the second camera includes a horizontal camera and a tilting camera, used to upload, collect, and save the child's endurance training process to the host computer during training.

[0007] The control panel includes a host and an operation panel. The host includes a data processing and analysis module, a data upload module, etc. The operation panel can control the host by touch screen operation, and can retrieve, view, process and analyze the information collected by the first camera and the second camera from time to time. The host computer stores examples of standard movements and postures for physical exercise. When a child performs physical exercise, the camera video data is automatically uploaded to the host computer, which then automatically compares the video with the example movements and makes an evaluation. The higher the similarity, the higher the test score. At the same time, after the score is obtained, it can be read aloud through the voice broadcast system.

[0008] A rolling device is provided above the flat plate. The rolling device includes a fixed frame, which is concave in shape and fixedly installed on the flat plate. A fixed ring is fixedly installed inside the fixed ring. A rotating block is slidably connected inside the fixed ring. Four sets of rotating blocks are evenly distributed inside the fixed ring. A rotating rod is fixedly connected to both ends of the inner side of the rotating block, and a first spring is fixedly connected to the middle end. A sliding sleeve is slidably connected to one end of the rotating rod. A second spring is provided between the top end of the rotating rod and the bottom end of the sliding sleeve. The second spring allows relative movement between the two. Under compression, the sliding sleeve can move towards the rotating rod.

[0009] When the sliding sleeve rotates around the central axis of the fixed ring, the rotating rod drives the rotating block to slide in a circle within the fixed ring.

[0010] Preferably, a clamping block is fixedly connected to one end of the rotating rod and the first spring. One end of the clamping block is provided with a ring, and one end of the clamping block is inserted into the inside of the ring. Four sets of clamping blocks are provided corresponding to the rotating block, and one end of the clamping block is slidably inserted into the inside of the ring. By rotating the ring, the clamping block can be driven to rotate, and then the rotating block is driven to make a frictional circular motion within the fixed ring through the first spring, the rotating rod and the sliding sleeve.

[0011] Preferably, the rolling device further includes a driving mechanism, the driving mechanism including a disk, and the two sides of the ring are fixedly connected to the disk; A second slide rail and a slider are provided between the disc and the sliding sleeve for sliding connection. The second slide rail is fixedly connected to the disc, and the slider is fixedly installed on the sliding sleeve. With the arrangement of the second slide rail and the slider, when the disc rotates, the disc can also drive the sliding sleeve and the rotating rod to rotate, and the disc does not interfere with the relative movement between the sliding sleeve and the rotating rod.

[0012] Preferably, a connecting rod is fixedly connected to one side of the disc, the connecting rod is inclined, a driving rod is fixedly connected to one end of the connecting rod, and one end of the driving rod is rotatably connected to both sides of the fixed frame; A locking rod is fixedly connected to the side of the drive rod, and a crank is fixedly connected to one end of the locking rod. By turning the crank and the locking rod, the drive rod and the connecting rod can drive the disk to rotate, and the drive rod and the connecting rod fix the position of the disk.

[0013] Preferably, an adjusting rod is threaded into the middle of the disc, and the diameter of one end of the adjusting rod decreases in a stepped manner. One end of the adjusting rod is located inside the ring, so that the clamping block rests on the adjusting rod. By adjusting the rod, as the adjusting rod is rotated further into the middle of the disc, the diameter of one end of the adjusting rod increases, pushing the clamping block outward. The clamping block moves the first spring, the rotating rod, and the sliding sleeve. Under the action of the first spring and the second spring, the friction between the rotating block and the fixed ring increases, and the force required to rotate the rotating block increases, allowing for adjustment of the force.

[0014] Preferably, a bench assembly is provided on one side of the rolling device. The bench assembly includes a retaining post, and connecting frames are fixedly connected to the upper and lower sides of the retaining post. A seat cushion is fixedly installed on one of the connecting frames, and the bottom of the other connecting frame is connected to the flat plate via a sliding plate and a first slide rail. The first slide rail is fixedly installed on the flat plate, and the sliding plate is fixedly connected to the bottom of the connecting frame.

[0015] Preferably, the middle end of the slide is threaded with a lead screw, one end of which is fixedly connected to a motor, and the other end passes through the bottom of the fixing frame and is rotatably connected to the fixing frame. The motor is fixedly installed in the mounting slot opened in the counterweight block. The motor can drive the lead screw to rotate, and the lead screw drives the slide to move left and right. When the slide moves to the right, the locking post can be locked on the locking rod, thus fixing the overall position of the bench assembly.

[0016] After the bench assembly is fixed in place, the child sits on the cushion with their feet on the crank handle, assumes a correct posture, and cranks the handle to rotate, thus exercising their feet, legs, and other parts of their body. The entire process is recorded by the horizontal camera in the second camera system.

[0017] Preferably, a tilting assembly is provided on the other side of the rolling device. The tilting assembly includes a frame, and the interior of the flat plate is a hollow structure. One end of the frame is slidably connected to the interior of the flat plate, and the other end of the frame is hinged to a reclining board. A support plate is hinged to the lower end of one end of the reclining board, and one end of the support plate rests against one end of the first slide rail. The reclining board is supported by the support plate, allowing the child to lie on it and place their hands on the crank handle to perform physical exercises for their hands, arms, and shoulders. The entire process is recorded by the tilting camera in the second camera.

[0018] Preferably, one end of the reclining board has a placement groove and a fitting groove inside, and the fitting groove is connected to the placement groove. When a child lies on the reclining board, his head can be placed in the placement groove with his face down, and the fitting groove allows the child's head to fit more closely to the placement groove.

[0019] This invention also provides a reward mechanism, which employs a gamified obesity management system for children as described above, specifically comprising the following steps: S1. When it is necessary to exercise the physical fitness of children's feet, legs, etc., the children sit on the cushion, place their feet on the crank handle, straighten their posture, and push the crank handle to rotate, so as to exercise the physical fitness of their feet, legs, etc. S2. When physical exercises are needed for children's hands, arms and shoulders, the support board can be used to raise the lying board, allowing the child to lie on it, place their hands on the crank handle, place their head in the placement slot, face down, and hold the crank handle to drive the rotating block back and forth. The rotating block rotates inside the fixed frame. S3. During the physical training period, the entire process is recorded by the horizontal camera in the second camera. The recording is automatically uploaded to the host. After the physical training is completed, the recording is compared and analyzed, and the physical training score is announced by voice. S4. Parents or guardians can set different prizes based on different score ranges and change the prizes from time to time to encourage children to perform exercises correctly and be more enthusiastic about exercising.

[0020] Compared with the prior art, the beneficial effects of the present invention are: This gamified obesity management system and reward mechanism for children replaces the existing spring-assisted training method with a rolling device. Combined with a bench and prone support components, it provides comprehensive physical exercise for multiple parts of the child's body. Furthermore, the various components can be adjusted to different positions before and after use, making it easy to store and store.

[0021] This gamified obesity management system and reward mechanism for children features an adjustable rotating block in the rolling device. The tension of the rotating block can be adjusted to follow the growth of the child's endurance and strength, making it convenient for children to use for training at different stages and increasing its practicality and applicability.

[0022] This gamified obesity management system and reward mechanism for children uses a first camera, a second camera, and a host and control panel in the console. The lighting displays guide children to perform regular exercises, and the scoring system for each physical exercise session gamifies the process. The combination of exercise scores and prizes attracts children's curiosity and motivates them to engage in gamified exercise. This encourages children's interest in endurance training, making physical exercise less boring and promoting their healthy growth. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] 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. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention. Example 1

[0034] Please see Figure 1A gamified obesity management system for children includes a tablet 1. Card sleeves 101 are fixedly installed at both ends of the tablet 1, and a counterweight 102 is fixedly connected to one end. An operating table 104 is fixedly installed above the counterweight 102 via a support frame 103. A handle 107 is fixedly connected to one side of the support frame 103. A first camera 105 is fixedly installed above the operating table 104, and a second camera 106 is fixedly installed below it. The first camera 105 is used to collect children's identity information, and the second camera 106 includes a horizontal camera and an oblique camera, which are used to upload, collect, and save the endurance training process of children to the host computer during training.

[0035] Specifically, the control panel 104 includes a host and an operation panel (both the host and the operation panel are fixedly installed inside the control panel 104 and are not shown in the figure). The host includes a data processing and analysis module, a data upload module, a timing module, and a rule judgment module, etc. The camera is connected to the host, and the operation panel can be used to control the host through touch screen operation, and the information collected by the first camera 105 and the second camera 106 can be retrieved, viewed, processed and analyzed from time to time.

[0036] The main unit also includes a light prompt system and a voice broadcast system (the light prompt system and voice broadcast system can be installed on the control panel 104, not shown in the figure); the light prompt system can guide children to perform regular movements through color changes, for example, setting a red light to indicate faster movements, a green light to indicate slower movements, and a yellow light to indicate sprinting to the limit; the voice broadcast system can accurately broadcast text in multiple languages ​​and also score the reading test.

[0037] The near-field recognition system based on wireless communication, in conjunction with the first camera 105, is used to identify each child's number and record his / her test data.

[0038] The timing module and rule judgment module can automatically record the physical exercise time, while the host computer stores examples of standard movements and postures for physical exercise. When children perform physical exercise, the camera video data is automatically uploaded to the host computer, and the rule judgment module in the host computer automatically compares it with the example movements and makes an evaluation. The higher the similarity, the higher the test score. At the same time, after the score is obtained, it can be read aloud through the voice broadcast system.

[0039] Specifically, in use, before children engage in physical exercise, they first study the example videos stored in the host. After studying, the exercise videos are captured by the first camera 105 and the second camera 106 and uploaded to the host. The host automatically compares and analyzes the test video with the example postures and movements, and scores the videos based on the similarity between the test video and the example videos. The higher the similarity, the higher the test score. After the score is obtained, it is announced through a voice broadcast system.

[0040] Through the coordinated operation of the aforementioned components, the system can guide children to perform regular exercises through color changes in the lighting system, and also provide incentives through reading tests and scores via the voice broadcast system. This attracts children's curiosity about exercise, enabling them to engage in a gamified exercise mode driven by their curiosity, thus preventing their exercise from becoming boring. Example 2

[0041] Please see Figure 1-5 Based on the above embodiments, the gamified obesity management system for children includes a rolling device on the top of the tablet 1. The rolling device includes a fixed frame 3, which is concave in shape and fixedly installed on the tablet 1. A fixed ring 301 is fixedly installed inside the fixed ring 301. A rotating block 302 is slidably connected inside the fixed ring 301. Four sets of rotating blocks 302 are evenly distributed inside the fixed ring 301. A rotating rod 303 is fixedly connected to both ends of the inner side of the rotating block 302, and a first spring 304 is fixedly connected to the middle end. A sliding sleeve 305 is slidably connected to one end of the rotating rod 303. A second spring is provided between the top end of the rotating rod 303 and the bottom end of one end of the sliding sleeve 305. The second spring allows relative movement between the two. Under compression, the sliding sleeve 305 can move towards the rotating rod 303.

[0042] When the sliding sleeve 305 rotates around the central axis of the fixed ring 301, the rotating rod 303 drives the rotating block 302 to slide circumferentially within the fixed ring 301.

[0043] A clamping block 308 is fixedly connected to one end of the rotating rod 303 and the first spring 304. A ring 309 is provided at one end of the clamping block 308. One end of the clamping block 308 is inserted into the ring 309. Four sets of clamping blocks 308 and rotating blocks 302 are provided in correspondence, and one end of the clamping blocks 308 is slidably inserted into the ring 309. By rotating the ring 309, the clamping blocks 308 can be rotated. Then, through the first spring 304, the rotating rod 303 and the sliding sleeve 305, the rotating block 302 is driven to make a frictional circular motion in the fixed ring 301.

[0044] Furthermore, the rolling device also includes a drive mechanism, which includes a disc 5, and the two sides of the ring 309 are fixedly connected to the disc 5. A second slide rail 306 and a slider 307 are provided between the disc 5 and the sliding sleeve 305 for sliding connection. The second slide rail 306 is fixedly connected to the disc 5, and the slider 307 is fixedly installed on the sliding sleeve 305. With the arrangement of the second slide rail 306 and the slider 307, when the disc 5 rotates, the disc 5 can also drive the sliding sleeve 305 and the rotating rod 303 to rotate, and the disc 5 does not interfere with the relative movement between the sliding sleeve 305 and the rotating rod 303.

[0045] A connecting rod 501 is fixedly connected to one side of the disc 5. The connecting rod 501 is tilted. A driving rod 502 is fixedly connected to one end of the connecting rod 501. One end of the driving rod 502 is rotatably connected to both sides of the fixed frame 3. A locking rod 503 is fixedly connected to the side of the drive rod 502. A crank 505 is fixedly connected to one end of the locking rod 503. By turning the crank 505 and the locking rod 503, the drive rod 502 and the connecting rod 501 can drive the disc 5 to rotate, and the drive rod 502 and the connecting rod 501 fix the position of the disc 5.

[0046] Furthermore, an adjusting rod 504 is threadedly connected to the middle end of the disc 5. The diameter of one end of the adjusting rod 504 decreases in a stepped manner. One end of the adjusting rod 504 is located inside the ring 309, so that the clamping block 308 rests on the adjusting rod 504. As the adjusting rod 504 is rotated further into the middle end of the disc 5, the diameter of one end of the adjusting rod 504 increases, pushing the clamping block 308 outward. The clamping block 308 moves the first spring 304, the rotating rod 303, and the sliding sleeve 305. Under the action of the first spring 304 and the second spring, the friction between the rotating block 302 and the fixed ring 301 increases, and the force required to rotate the rotating block 302 increases, allowing for adjustment of the force.

[0047] Specifically, in use, when the rolling device is needed for physical exercise, turning the handle 505 and the lever 503 causes the drive rod 502 and the connecting rod 501 to rotate the disc 5. The disc 5 then rotates the ring 309, which in turn causes the clamping block 308 to rotate. This, in turn, causes the rotating block 302 to make a frictional circular motion within the fixed ring 301 via the first spring 304, the rotating rod 303, and the sliding sleeve 305. At the same time, when the disc 5 rotates, it also causes the sliding sleeve 305 and the rotating rod 303 to rotate, and the disc 5 does not interfere with the relative movement between the sliding sleeve 305 and the rotating rod 303.

[0048] When it is necessary to adjust the friction between the rotating block 302 and the fixed ring 301 to increase the user's force requirements, the adjusting rod 504 is rotated deeper into the middle of the disc 5. As the diameter of one end of the adjusting rod 504 increases, it pushes the clamping block 308 outward. Under the action of the first spring 304 and the second spring, the friction between the rotating block 302 and the fixed ring 301 increases, and the force required to rotate the rotating block 302 increases, thereby allowing for the adjustment of the force required.

[0049] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 3

[0050] Please see Figure 1 and Figure 6 Based on the above embodiments, the child gamified obesity management system has a bench assembly on one side of the rolling device. The bench assembly includes a locking post 201, and connecting frames 2 are fixedly connected to the upper and lower sides of the locking post 201. A seat cushion 202 is fixedly installed on one connecting frame 2, and the bottom of the other connecting frame 2 is connected to the flat plate 1 by setting a sliding plate 203 and a first slide rail 204. The first slide rail 204 is fixedly installed on the flat plate 1, and the sliding plate 203 is fixedly connected to the bottom of the connecting frame 2.

[0051] The middle end of the slide 203 is threaded with a lead screw 206. One end of the lead screw 206 is fixedly connected to a motor 205, and the other end passes through the bottom of the fixing frame 3 and is rotatably connected to the fixing frame 3. The motor 205 is fixedly installed in the mounting slot opened in the counterweight block 102. The motor 205 can drive the lead screw 206 to rotate, and the lead screw 206 drives the slide 203 to move left and right. When the slide 203 moves to the right, the locking post 201 can be locked on the locking rod 503, thus fixing the overall position of the bench assembly.

[0052] After the bench assembly is fixed in place, the child sits on the seat cushion 202, places his feet on the crank handle 505, straightens his posture, and pushes the crank handle 505 to rotate, thus exercising his feet, legs and other parts of his body. The entire process is recorded by the horizontal camera in the second camera 106.

[0053] Specifically, in use, when physical exercise is needed for children's feet, legs, etc., the motor 205 drives the lead screw 206 to rotate. The lead screw 206 drives the slide 203 to move to the right, so that the locking post 201 is just locked on the locking rod 503, fixing the overall position of the bench assembly. After the position is fixed, the child sits on the seat cushion 202, places his feet on the crank handle 505, straightens his posture, and pushes the crank handle 505 to rotate, performing physical exercise for his feet, legs, etc. The whole process is recorded by the horizontal camera in the second camera 106. After recording, it is automatically uploaded to the host, compared and analyzed, and the score is announced by voice.

[0054] When the force needs to be adjusted, the adjusting rod 504 is moved deeper or further away from the center of the disc 5 to increase or decrease the friction between the rotating block 302 and the fixed ring 301, thereby adjusting the force.

[0055] It should be noted that after physical exercise, the screw 206 is driven to rotate in the opposite direction by the reverse motor 205, which moves the entire bench assembly and places it under the operating table 104.

[0056] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 4

[0057] Please see Figure 1 and Figure 7 Based on the above embodiments, the gamified obesity management system for children preferably includes a tilting component on the other side of the rolling device. The tilting component includes a frame 4, and the interior of the flat plate 1 is hollow. One end of the frame 4 is slidably connected to the interior of the flat plate 1, and the other end of the frame 4 is hinged to a lying board 401. A support plate 402 is hinged to the lower end of one end of the lying board 401. One end of the support plate 402 rests against one end of the first slide rail 204. The lying board 401 is supported by the support plate 402, allowing the child to lie on it and place their hands on the crank 505 to perform physical exercises for their hands, arms, and shoulders. The entire process is recorded by the tilting camera in the second camera 106.

[0058] The reclining board 401 has a placement groove 403 and a fitting groove 404 inside one end. The fitting groove 404 is connected to the placement groove 403. When a child lies on the reclining board 401, his head can be placed in the placement groove 403 with his face down. The fitting groove 404 makes the child's head fit more closely to the placement groove 403.

[0059] Specifically, when using the bench, when it is necessary to exercise the physical fitness of a child's hands, arms and shoulders, the entire bench assembly should be moved and placed under the operating table 104.

[0060] The lying board 401 is then supported by the support plate 402, allowing the child to lie on it, place their hands on the crank 505, and place their head in the placement slot 403 with their face down. The child holds the crank 505 and rotates the drive block 302 back and forth. The drive block 302 rotates inside the fixed frame 3, which can stretch the muscles of the hands, arms, and shoulders, as well as the back, thus requiring strength in the arms and thus providing physical exercise. The entire process is recorded by the tilting camera in the second camera 106. After recording, the video is automatically uploaded to the host, compared and analyzed, and the score is announced by voice.

[0061] When the force needs to be adjusted, the adjusting rod 504 is moved deeper or further away from the center of the disc 5 to increase or decrease the friction between the rotating block 302 and the fixed ring 301, thereby adjusting the force.

[0062] It should be noted that after using the reclining assembly, the frame 4 can be pulled out from inside the flat plate 1, the support plate 402 can be placed under the reclining plate 401, the reclining plate 401 can be placed inside the frame 4, and finally the frame 4 can be placed inside the flat plate 1.

[0063] The solution in this embodiment can be selectively combined with solutions in other embodiments.

[0064] This invention also provides a reward mechanism, which employs a gamified obesity management system for children as described in the above embodiments, specifically comprising the following steps: S1. When it is necessary to exercise the physical fitness of children's feet, legs and other parts, the children sit on the seat cushion 202, place their feet on the crank handle 505, straighten their posture, and push the crank handle 505 to rotate, so as to exercise the physical fitness of their feet, legs and other parts. S2.
