Description

Technical Field

[0001] This invention relates to the field of children's products, specifically to a wearable child sitting posture monitoring device and monitoring method. Background Technology

[0002] For a long time, although parents and teachers have provided correct education and requirements for students' sitting posture when reading and writing, the myopia rate has remained high, and the age of onset of myopia has also shown a trend of becoming younger. Since the reasons are multifaceted, this has attracted the attention of all sectors of society.

[0003] Currently, most child posture monitoring devices on the market that are mainly based on mechanical structures have limited usage methods. For example, a pillar is set up on the side of the table to support the child's chin, so that the child cannot lower their head. However, this method is too rigid, and having a plastic or wooden pillar on the table is not only unsightly, but also poses a certain danger. Furthermore, it is inconvenient to carry and cumbersome to disassemble.

[0004] In addition, a type of posture correction chair has appeared on the market. This chair is usually made of wood and has the following drawbacks during use: First, the chair does not have a device specifically designed to stabilize the child's upper body, so the child is prone to swaying, which is not conducive to correcting their posture and results in poor correction effect; second, the chair is heavy and takes up a lot of space, making it inconvenient to move and carry, and cannot be used to correct the child's posture anytime and anywhere; third, the size of the chair cannot be adjusted, and different models of chairs need to be purchased as the child grows and their body size changes, which is expensive and increases the family's financial burden. As a result, the existing posture correction chair has a narrow range of applications, and it not only only restricts the child's posture but also cannot correct the child's bending over, crossing legs, and sideways movements.

[0005] Meanwhile, children are naturally active and playful. If a posture monitoring device uses a large number of sophisticated electronic components, children may damage it during use. The working principle of a monitoring device that uses sophisticated electronic components is as follows: when the human body acts on the force sensing unit, a feedback signal is obtained to obtain a pressure value. The body pressure distribution index value is obtained through statistics and calculation. Finally, the body pressure distribution index value is used to detect the child's sitting posture in real time. However, this method still has limitations. When the child needs to use a cushion or change positions, the monitoring device cannot move with the child. Therefore, it needs to be installed in the child's study area in advance.

[0006] Therefore, it is necessary to design a wearable sitting posture monitoring device and monitoring method for children. Summary of the Invention

[0007] Therefore, it is necessary to provide a wearable sitting posture monitoring device and monitoring method for children to address the problems of existing technologies.

[0008] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

[0017] Furthermore, the second monitoring mechanism also includes an active pulley and four second magnetic buckles. The leg-binding mechanism also includes a leg-binding base, a leg-binding clasp, a traction belt, an adapter pulley, and a power pulley. Two second magnetic buckles are connected to the upper end of the back strap, and two second magnetic buckles are connected to the middle of the back strap. Two second magnetic buckles on the same vertical plane attract each other. The active pulley is driven to the lower end of the back strap. The active pulley is rotatably connected to the second support box through a spring wheel seat. The power pulley is located next to the active pulley through a spring wheel seat.

The four power gears are coaxially connected to the drive pulley and the two power pulleys, respectively. The power rack is located beside the power gear and meshes with it. The transfer gear is located at the upper end of the third support box and meshes with the power rack. The transfer residual tooth is coaxially arranged with the transfer gear. The two reciprocating racks are symmetrically arranged on the upper and lower sides of the transfer residual tooth. The rotation of the transfer residual tooth allows it to mesh with the two reciprocating racks in sequence. The limit tooth seat is located beside the two reciprocating racks and is slidably connected to them through a support plate.

[0040] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0041] refer to Figures 1 to 9 A wearable posture monitoring device for children includes:

[0042] The waist-binding assembly 1 includes a first support box 2, two waist-binding rings 3 and two first monitoring mechanisms 7. The first support box 2 is set in a horizontal position, and the two waist-binding rings 3 are symmetrically staggered and slidably connected to the first support box 2. The two waist-binding rings 3 can be locked on the child's waist.

[0043] The first monitoring mechanism 7 is connected to the middle of the two waist rings 3 respectively, and includes an inclined baffle 8 and a first contact rod 15. The inclined baffle 8 is located in the inner ring of the waist ring 3, and the first contact rod 15 is located at the upper end of the inclined baffle 8. The first contact rod 15 can contact the child's waist when the child's spine is misaligned.

[0044] The support mechanism 16 is connected to the first support box 2 and includes a lumbar pillow 17. The lumbar pillow 17 is located on the side of the first support box 2 near the two inclined baffles 8. The lumbar pillow 17 can support the child's waist.

[0045] The second monitoring mechanism 25 includes a second support box 26, a third support box 27, a carrying strap 28, two leg restraint mechanisms 31, and four tapping mechanisms 48. The second support box 26 is located on the side of the first support box 2 away from the two waist rings 3. The third support box 27 is located at the upper end of the second support box 26. The four tapping mechanisms 48 are located inside the second support box 26. The two leg restraint mechanisms 31 are respectively connected to the two outermost tapping mechanisms 48. The lower end of the carrying strap 28 extends into the second support box 26 and is connected to the other two tapping mechanisms 48. The four tapping mechanisms 48 can gently tap the back of the child when the child's sitting posture is not correct.

[0046] When the device is in operation, the child first puts the two waist-binding rings 3 around their waist, then adjusts the vertical position of the lumbar pillow 17 so that the child's waist can be supported by the lumbar pillow 17. After the position of the lumbar pillow 17 is determined, the child then fastens the upper end of the shoulder strap 28 to their shoulders, and finally the child connects the two leg-binding mechanisms 31 to their two thighs. During the child's learning process, when the child's posture is not correct and the body shifts, causing scoliosis, the side of the child's body will abut against the inclined baffle 8. Then, the first contact rod 15 set at the upper end of the inclined baffle 8 will abut against the side of the child's body. At this time, the child can adjust their sitting posture after being abutted. When the child bends over, the shoulder strap 28 will be tightened. At this time, the two tapping mechanisms 48 connected to the lower end of the shoulder strap 28 will gently tap the child's back. When the child crosses their legs, the two leg-binding mechanisms 31 connected to the child's thighs will drive the two tapping mechanisms 48 connected to them to gently tap the child's back, thereby realizing real-time monitoring of the child's sitting posture.

[0047] In order to stabilize the child's waist, the following features are specifically designed:

[0048] The waist-cinching assembly 1 also includes a first pin 5 and two first magnetic snaps 6. Each of the two waist-cinching rings 3 has a first limiting perforation 4. The first pin 5 passes downward through the first support box 2 and is slidably connected to the two first limiting perforations 4. The two first magnetic snaps 6 are respectively located at the ends of the two waist-cinching rings 3 furthest from the first pin 5, and the two first magnetic snaps 6 can attract each other. During use, to ensure that the two waist-cinching rings 3 can better position the child's waist, parents can tighten the first pin 5 to limit the relative friction between the two waist-cinching rings 3, ensuring that the waist-cinching rings 3 will not be easily opened after being secured by the two first magnetic snaps 6.

[0049] In order to alert children when their spine is twisted, the following features are specifically included:

[0050] The first monitoring mechanism 7 also includes an inclined linkage plate 10, a first rack 12, a first gear 13, a second rack 14, two inclined pins 9, and two inclined tension springs 11. One end of the two inclined pins 9 is fixedly connected to the inclined baffle 8. The inclined linkage plate 10 is fixedly connected to one end of the two inclined pins 9 that passes through the waist ring 3. The two inclined tension springs 11 are respectively sleeved on the outside of the two inclined pins 9. One end of the two inclined tension springs 11 is connected to the waist ring 3, and the other end is connected to the inclined linkage plate 10. The first rack 12 is slidably disposed on the upper end of the waist ring 3 and one end is connected to the inclined linkage plate 10. The first gear 13 is disposed on the upper end of the first rack 12 and meshes with the first gear 13. The second rack 14 is disposed on the upper end of the first gear 13 and meshes with the first gear 13. The end of the second rack 14 away from the inclined linkage plate 10 is connected to the first contact rod 15. When a child's spine twists, the child's side will abut against the tilting baffle 8. After the tilting baffle 8 moves, it will drive the tilting linkage plate 10 to move via two tilting pins 9. The tilting linkage plate 10, after moving, will drive the first gear 13 meshing with it to rotate via the first rack 12. The first gear 13 will then drive the second rack 14 meshing with it to move. The second rack 14, after moving, will drive the first contact rod 15 connected to it to abut against the child's side, reminding the child of incorrect posture. During this process, two tilting tension springs 11 are used to reset the tilting baffle 8 after it has moved.

[0051] To accommodate children of different body types and heights, the following features were specifically designed:

[0052] The support mechanism 16 also includes a sliding support plate 18, a limiting rod 19, a limiting rod seat 20, several movable rods 21, several movable rod seats 22, several movable pins 23, and several movable springs 24. The sliding support plate 18 is fixedly connected to the side of the lumbar pillow 17 near the first support box 2. The limiting rod seat 20 is adjustablely disposed at the upper end of the first support box 2. The limiting rod 19 is fixedly connected to the upper end of the limiting rod seat 20. Several movable rods 21 are linearly arranged on the sliding support plate 18. On the side near the limiting rod 19, several movable rods 21 can abut against the limiting rod 19. Several movable rod seats 22 are respectively set at the ends of the several movable rods 21 away from the limiting rod 19. One end of several movable pins 23 is connected to the limiting rod 19, and the other end is slidably connected to the movable rod seat 22. Several movable springs 24 are respectively sleeved on the outside of the several movable pins 23. One end of several movable springs 24 is connected to the limiting rod 19, and the other end is connected to the movable rod seat 22. During the use of the device, in order to accommodate different children's body shapes and heights, parents can adjust the height of the lumbar pillow 17. At this time, when the parent pulls the lumbar pillow 17 upward, the movement of the lumbar pillow 17 will drive the sliding support plate 18 to move upward. The movement of the sliding support plate 18 will drive the movement of several movable rods 21 connected to it. During the movement, the movable rods 21 will abut against the limiting rod 19. At this time, the position of the lumbar pillow 17 can be determined. Under the action of the movable spring 24, the movable rods 21 will press against the limiting rod 19. Several movable rods 21 represent several height levels, and parents can pre-adjust according to the child's height.

[0053] In order to monitor children's legs, the following features were specifically designed:

[0054] The second monitoring mechanism 25 also includes a drive pulley 29 and four second magnetic buckles 30. The leg-binding mechanism 31 also includes a leg-binding base 32, a leg-binding shackle 33, a traction belt 34, an adapter pulley 35, and a power pulley 36. Two second magnetic buckles 30 are connected to the upper end of the back strap 28, and two second magnetic buckles 30 are connected to the middle of the back strap 28. Two second magnetic buckles 30 located on the same vertical plane attract each other. The drive pulley 29 is connected to the lower end of the back strap 28 via a drive mechanism. The drive pulley 29 is connected to the back strap 28 via a spring wheel seat. The second support box 26 is rotatably connected. The power pulley 36 is set next to the drive pulley 29 through the spring wheel seat. The adapter pulley 35 is set at the lower end of the second support box 26. One end of the traction belt 34 is connected to the power pulley 36 for transmission, and the other end extends downward around the adapter pulley 35. The leg base 32 is fixedly connected to the end of the adapter pulley 35 that extends out of the adapter pulley 35. The leg retainer 33 is slidably connected to the leg base 32. The power pulley 36 and the drive pulley 29 are connected to the corresponding striking mechanism 48. In order to monitor the child's legs when using the device, the child can put their thigh into the leg-binding base 32 and then press the leg-binding buckle 33 to tighten the thigh. When the child crosses their legs, the leg-binding base 32 will move, which will then drive the traction belt 34 to move. The movement of the traction belt 34 will drive the power pulley 36 to rotate, which will drive the tapping mechanism 48 to operate. Then the tapping mechanism 48 will gently tap the child's back to remind the child to pay attention to their sitting posture.

[0055] To ensure that the leg restraint ring 33 does not move toward the child's hip under the action of the traction belt 34, the following features are specifically designed:

[0056] The leg restraint mechanism 31 also includes an adjusting sleeve rod 37, an adjusting insert rod 39, an adjusting pin 41, a connecting linkage rod 42, and a connecting fork rod 43. The connecting fork rod 43 abuts against the upper end of the leg restraint ring 33. The connecting linkage rod 42 is fixedly connected to the upper end of the connecting fork rod 43. One end of the adjusting insert rod 39 is hinged to the connecting linkage rod 42. One end of the adjusting sleeve rod 37 is slidably connected to the other end of the adjusting insert rod 39. The adjusting insert rod 39 has several adjusting holes 40 formed at equal intervals. The adjusting sleeve rod 37 has sliding holes 38 formed. The adjusting pin 41 passes downward through the sliding holes 38 and the corresponding adjusting holes 40. When a child uses the leg restraint 33, in order to ensure that the leg restraint 33 does not move toward the child's hip under the action of the traction belt 34, the adapter fork 43 will abut against the leg restraint 33. At this time, the leg restraint 33 will have a force away from the child's hip. Meanwhile, the adjusting sleeve 37 and the adjusting insert 39 can be adjusted by adjusting the adjusting pin 41 to accommodate the leg length of children of different ages.

[0057] To improve comfort for children, the following features are specifically included:

[0058] The leg-binding mechanism 31 also includes a positioning arc block 44, a sliding arc block 47, and a positioning spring 46. The positioning arc block 44 has a positioning groove 45 formed on it, and is fixedly connected to the waist-binding ring 3. The sliding arc block 47 is slidably connected to the positioning groove 45. The positioning spring 46 is disposed within the positioning groove 45, with one end connected to the positioning arc block 44 and the other end connected to the sliding arc block 47. The sliding arc block 47 is hinged to the other end of the adjusting sleeve rod 37. When a child uses the leg-binding ring, to ensure that the child's legs are not excessively restricted, thereby improving the child's comfort, the sliding arc block 47 can move within the positioning groove 45. The positioning spring 46 allows the sliding arc block 47 to maintain a tendency to move towards the center of the waist-binding ring 3, thereby increasing the freedom of the leg-binding ring 33.

[0059] In order to enable tapping on a child's back, the following features were specifically designed:

[0060] The striking mechanism 48 includes a power gear 49, a power rack 50, a transition gear 51, a transition residual tooth 52, a second contact rod 56, a limit gear seat 54, a return spring 55, and two reciprocating racks 53. The four power gears 49 are coaxially connected to the drive pulley 29 and the two power pulleys 36, respectively. The power rack 50 is located beside and meshes with the power gears 49. The transition gear 51 is located at the upper end of the third support box 27 and meshes with the power rack 50. The transition residual tooth 52 is connected to the transition gear 56. 1. The two reciprocating racks 53 are arranged symmetrically on the upper and lower sides of the transition residual tooth 52. The transition residual tooth 52 can rotate and mesh with the two reciprocating racks 53 in sequence. The limiting tooth seat 54 is arranged on the side of the two reciprocating racks 53 and is slidably connected to them through the support plate. One end of the return spring 55 is connected to the inner wall of the third support box 27, and the other end is connected to the support plate on the reciprocating rack 53. One end of the second contact rod 56 is connected to the support plate on the reciprocating rack 53, and the other end extends out of the third support box 27. When the baby carrier 28 or the two traction straps 34 move, the corresponding power gear 49 will rotate. The rotation of the power gear 49 will drive the power rack 50 connected to it to move. The movement of the power rack 50 will drive the adapter gear 51 meshing with it to rotate. The rotation of the adapter gear 51 will drive the adapter residual tooth 52 connected to it to rotate. The rotation of the adapter residual tooth 52 will drive the two reciprocating racks 53 meshing with it to move back and forth. The movement of the reciprocating racks 53 will drive the second touch rod 56 to move through the support plate. When the second touch rod 56 moves, it can gently tap the child's back.

[0061] A monitoring method for a wearable child sitting posture monitoring device further includes the following monitoring steps:

[0062] S1: When a child crosses their legs, the corresponding leg-binding mechanism 31 can drive the corresponding tapping mechanism 48 to gently tap the child's back as the child's legs move.

[0063] S2: When a child's back spine curves due to a tilted sitting posture, the corresponding first touch bar 15 will contact the side of the child's waist to remind the child to adjust their sitting posture;

[0064] S3: When the child bends over, the strap 28 will be pulled and the two tapping mechanisms 48 connected to it will gently tap the child's back.

[0065] The working principle of this device is as follows: When the device is in use, the child first puts the two waist-binding rings 3 around his / her waist, then adjusts the vertical position of the waist pillow 17 so that the child's waist can be supported by the waist pillow 17. After the position of the waist pillow 17 is determined, the child then fastens the upper end of the carrying strap 28 to his / her shoulders. Finally, the child connects the two leg-binding rings 33 to his / her thighs and presses the two connecting forks 43 against the corresponding leg-binding rings 33 to prevent the two leg-binding rings 33 from slipping towards the child's crotch and affecting the child's learning during the use of this device.

[0066] During a child's learning process, when the child's spine curves due to improper posture, the side of the child's body will come into contact with the inclined baffle 8. Subsequently, the first contact rod 15 located at the upper end of the inclined baffle 8 will contact the side of the child's body. When the child is contacted, he can adjust his posture. When the child bends over, the carrier strap 28 will be tightened. At this time, the drive pulley 29 connected to the lower end of the carrier strap 28 will rotate. The rotation of the drive pulley 29 will drive the two second contact rods 56 above it to gently tap the child's back.

[0067] When a child crosses their legs, the two leg-binding rings 33 connected to the child's thighs will drive the corresponding second touch rods 56 to gently tap the child's back, thereby achieving real-time monitoring of the child's sitting posture.
