Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of shoulder straps, and more particularly to a shoulder strap capable of adaptively adjusting tightness according to a human body's movement posture and an adjustment method thereof. Background Art
[0002] An upright and elegant posture is the basis of a good external image. Modern people's lifestyle and working style can easily lead to hunched backs and uneven shoulders, which affect health and personal temperament. Sitting posture is the most common posture for office workers, school-age teenagers and other groups. A suitable sitting posture can prevent people who work and study at a desk for a long time from fatigue. At the same time, a bad sitting posture can easily lead to discomfort in the lumbar spine, cervical spine and shoulder joints. Statistics show that the incidence of scoliosis in adolescents aged 6-16 in my country has reached 3%, which seriously threatens the health of young students. Long-term bad sitting posture of primary and secondary school students is an important cause of symptoms such as decreased vision, scoliosis, and uneven shoulders. Real-time monitoring of office work or school-age teenagers' learning, further feedback and warning of users' bad sitting posture, and targeted intervention are effective measures to correct body posture.
[0003] At present, the products for correcting body posture are mainly braces, which are basically divided into two categories: the first category is a completely passive brace, which provides auxiliary force to correct sitting posture or body posture by manually adjusting the tightness; the second category provides vibration or sound warning based on the monitoring of body posture angle to warn users to adjust themselves. Chinese patent CN201920069147 discloses a smart brace that can monitor and correct upper limb posture, monitors the degree of back curvature through flexible curvature sensor elements, and helps users develop a good sitting posture and prevent hunchback by issuing reminder signals. Chinese patent CN20192041902 discloses a smart brace that can monitor and correct sitting posture, monitors the human spine angle through the MCU chip and gyroscope on the brace to give warnings, and users stretch the straps to adjust the tension to adjust the sitting posture. Chinese patent CN201910454150 discloses an automated spinal correction garment, which controls the stepper motor to "tighten" or "loosen" the brace worn on the upper body through a manual button to achieve the purpose of adjusting the back posture of the human body. However, the patent did not disclose the innovative design of the straps, and still mainly used elastic universal straps, which were bulky and inconvenient to wear. More importantly, the above patent did not monitor the body posture based on the posture sensor, did not realize the motor control capability based on body posture judgment, and did not control the motor to automatically and adaptively adjust the tension of the straps. It was impossible to avoid the influence of subjective factors such as human laziness during use, which greatly affected the use effect and user experience.
[0004] The existing technologies are not effective enough and have poor adaptability in preventing and treating various symptoms caused by improper posture, which is mainly reflected in the following aspects:
[0005] 1. Most of them remind you in various ways, such as vibration, sound or airbag. These reminders are mainly to make you sit up straight and correct yourself. There is no auxiliary guidance function. However, in fact, the sitting and correction posture of the user is different each time, which cannot play a corrective therapeutic role.
[0006] 2. Others remind users by detecting the pressure caused by bad posture of users. Users are required to adjust the tightness of the straps every time. As mentioned in the first point, since the sitting posture is different each time, the correction effectiveness and adaptability of this technology are still poor. Summary of the invention
[0007] The technical problem to be solved by the present invention is that the prior art is insufficiently effective and poorly adaptable in preventing and treating various symptoms caused by improper posture.
[0008] In view of the above problems, a wearable self-adjustable brace is provided which can automatically correct body posture and prevent symptoms such as hunchback and scoliosis, so as to solve the above problems.

[0014] According to the adaptively adjustable shoulder strap of the present invention, in a first possible implementation manner, the posture sensing module includes one or more of 1 to 3 three-axis gyroscopes with an accuracy of 0.1°.
[0015] According to the first possible implementation of the present invention, in a second possible implementation, the three three-axis gyroscopes are installed in a triangle to detect the front-back and left-right tilt angles of the shoulder.
[0016] According to the adaptively adjustable shoulder strap described in the present invention, in a third possible implementation method, the strap system includes a flexible strap, a hollow connecting strap, an elastic elastic cord and a power mechanism, the flexible strap is worn on the shoulder and the waist respectively, the hollow connecting strap is T-shaped, connecting the flexible straps on the left and right shoulders and the waist, and the elastic elastic cord passes through the hollow connecting strap and is connected to the flexible straps on the left and right shoulders and the waist and the driving device of the power mechanism respectively.
[0017] According to the third embodiment of the present invention, in a fourth possible implementation, the strap system also includes a fixing plate, which is arranged in the vertical direction of the hollow connecting belt, and the power mechanism is arranged on the fixing plate. The driving device tightens or loosens the left and right shoulder and waist flexible straps by winding the elastic elastic rope.
[0018] According to the fourth embodiment of the present invention, in a fifth possible implementation, the driving device includes a first reel, a driving gear, a second reel and a plurality of pulleys, one end of the first reel is directly connected to the motor or connected through a transmission gear, and the other end is connected to the second reel gear, the plurality of pulleys are respectively arranged at the connection positions of the left and right shoulders, the waist flexible winding belt and the fixed plate, the elastic elastic rope passes through the pulley and is wound around the first reel and the second reel.
[0019] In a second aspect, an adaptive strap adjustment method includes:
[0020] Detect the left and right tilt angle of the user's shoulders or the shoulder-back angle;
[0021] If the left-right inclination angle of the user's shoulders or the shoulder-back angle exceeds the angle threshold, the power mechanism tightens the horizontal elastic elastic rope or the vertical elastic elastic rope to the maximum tension value, and guides the user to correct the posture through the tension;
[0022] If the left-right tilt angle of the user's shoulder or the shoulder-back angle exceeds the angle threshold, the adaptive adjustment tension value continues to exceed the specified time, the power mechanism is reversed, and the elastic bungee tension is reduced to zero.

The posture sensing module and tension detection module set can monitor the left and right inclination angles of the user's shoulders and the shoulder-back angle in real time. When the body posture inclination exceeds the threshold, the adaptive adjustment module adjusts the tension to the maximum tension value threshold of the corresponding mode according to the control module instruction to remind the user. More importantly, the tension value is used to guide the user to correct the posture.

DETAILED DESCRIPTION
[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0043] The technical problem to be solved by the present invention is that the prior art is insufficiently effective and poorly adaptable in preventing and treating various symptoms caused by improper posture.
[0044] In view of the above problems, a wearable self-adjustable brace is provided which can automatically correct body posture and prevent symptoms such as hunchback and scoliosis, so as to solve the above problems.
[0045] An adaptive adjustment strap, such as Figure 1 , Figure 1The first embodiment of the present invention is a logical connection diagram of an adaptively adjustable shoulder strap, including a strap system 150 and an adaptive control system. The adaptive control system is used to control the strap system 150 to tighten or loosen according to user instructions or thresholds, including a posture sensing module 130, an adaptive adjustment module 140, a control module 110 and a tension detection module 120; the posture sensing module 130 is used to monitor the front and back, left and right inclination angles of the shoulder, and transmit the angle data to the control module 110; the adaptive adjustment module 140 is used to respond to the instructions sent by the control module 110 according to the signal of the posture sensing module 130, and control the operation of the strap system 150 to assist the user in correction; the tension detection module 120 is used to detect the tension of the strap and transmit the tension data to the control module 110; the control module 110 is used to process the data of the posture sensing module 130 and the tension detection module 120, send instructions to the adaptive adjustment module 140, obtain the shoulder inclination angle and the strap tension threshold, judge whether the inclination angle or the strap tension threshold exceeds the threshold and switch the working mode.
[0046] The posture sensing module 130 monitors the user's front and back and left and right tilt angles in real time. The front and back tilt angle can be the angle between the shoulders and back, and an increase in the angle indicates that the user is sitting with a hunched back. The left and right tilt angles can be the user's left and right tilt posture, or the user's high and low shoulder posture, which can be monitored by the posture sensing module 130 and output to the control module 110 for evaluation and judgment.
[0047] In some implementations, the posture sensing module 130 uses a three-axis gyroscope to monitor the user's body angle. One to three three-axis gyroscopes may be used with an accuracy of 0.1°.
[0048] In some embodiments, when three three-axis gyroscopes are used, the three three-axis gyroscopes are installed in a triangle to detect the front-back and left-right tilt angles of the shoulder.
[0049] The adaptive adjustment module 140 directly controls the strap system 150 to automatically adjust the tension of the elastic bungee 153 to assist in correcting the user's posture. The specific user first selects a working mode, first, selects "sitting mode" or "standing mode", presses the "left and right locking" key, controls the motor 1541 of the left and right elastic bungee 153 of the shoulder to rotate and slowly tighten until the user feels that the tension is appropriate, releases the "left and right locking" key, and at this time the tension detection module 120 records the tension value of the left and right elastic bungee 153 and sets it as the left and right tension threshold.
[0050] Then, press the "up and down locking" button to control the motor 1541 of the upper and lower elastic bungee cords 153 on the back to rotate and start to slowly tighten until the user feels the tension is appropriate, and release the "up and down locking" button. At this time, the tension detection module 120 records the tension values of the upper and lower elastic bungee cords 153 and sets them as upper and lower tension thresholds.
[0051] It should be noted that before formally correcting the user's posture, it is necessary to first initialize to obtain the best tension threshold. A tension value that is too small is not conducive to auxiliary correction, and a tension value that is too large will make the user feel uncomfortable. Therefore, it is very important to obtain the best tension value threshold. In this application, the adaptation can not only adjust the tension value in time for auxiliary correction, but also learn according to the user's physical condition to obtain the best tension value threshold.
[0052] After obtaining the best threshold, correction is performed according to the user's selected mode. When it is detected that the user's posture is not correct, the adaptive adjustment module 140 controls the strap system 150 to increase the tension of the front, back, left, and right elastic ropes 153 to assist in correction. After a certain period of time, such as 10 seconds, after the user corrects the posture, the motor 1541 of the strap system 150 automatically rotates in the reverse direction to loosen the elastic rope 153 to prevent the user from feeling uncomfortable due to long-term high tension.
[0053] The user posture perception module 130 monitors the angles of the user's left and right shoulders in real time. For example, when the line connecting the two shoulders of the user exceeds a certain angle of the horizontal line, such as 5 degrees, the adaptive adjustment module 140 controls the strap system 150 to start the motor 1541 to tighten the left and right elastic ropes 153 to the threshold value, maintain the maximum tension for 10 seconds, and if the posture does not change, loosen the straps.
[0054] The user posture sensing module 130 monitors the angle of the upper and lower shoulder of the user in real time. When the user hunches over a certain angle, such as 5 degrees, the adaptive adjustment module 140 controls the strap system 150 to start the motor 1541 to tighten the upper and lower elastic ropes 153 to the threshold value, and maintain the maximum tension for 10 seconds. If the posture does not change, the strap is loosened. If the body posture is not correct again, the motor 1541 is started again to correct it.
[0055] If the user wants to relax briefly and does not use the correction strap, the user presses the button to select the relaxation mode. At this time, the motor 1541 does not work, and the tension of the strap is extremely small, 0-5N, and the user can hardly feel the tension of the strap.
[0056] When the body posture tilt exceeds the threshold, such as Figure 5 , Figure 5This is a structural schematic diagram of the fifth embodiment of an adaptively adjustable shoulder strap in the present invention. The adaptive adjustment module 140 adjusts the tension to the maximum tension value threshold of the corresponding mode according to the instruction of the control module 110 to remind the user. More importantly, the user is guided to correct the posture through the tension value. After the user corrects to the corresponding posture, the tension value gradually recovers to the tension value threshold corresponding to the mode, and then the correction is completed. Adaptive adjustment is adopted to determine the tension value and posture angle of the correct posture, and the tension is used to assist the user in correction, which solves the problems of the prior art that only reminders are provided but the effectiveness and poor adaptability of assisting the user to correct to the correct posture cannot be solved.
[0057] In some embodiments, the adaptive adjustment module 140 controls the strap system 150 to adjust the body posture by adjusting the tension value, and the tension value range of the left and right elastic elastic cords 153 is 0-50N, preferably 0-30N. The tension value range of the upper and lower elastic elastic cords 153 is 0-100N, preferably 0-60N. The tightening speed is 0-5cm / s, preferably 0-3cm / s. The tension range of the left and right and upper and lower shoulder straps in the strap system 150 is 0-100N, preferably 0-60N.
[0058] In some embodiments, Figure 2 , Figure 2 This is a structural schematic diagram of the second embodiment of an adaptively adjustable shoulder strap in the present invention, the strap system 150 includes a flexible belt 152, a hollow connecting belt, an elastic bungee cord and a power mechanism, the flexible belt 152 is worn on the shoulder and the waist respectively, the hollow connecting belt is T-shaped, connecting the flexible belts 152 on the left and right shoulders and the waist, the elastic bungee cord 153 passes through the hollow connecting belt and is respectively connected to the flexible belts 152 on the left and right shoulders, the flexible belt 152 on the waist and the driving device 154 of the power mechanism, the horizontal and vertical lengths of the hollow connecting belt are respectively greater than the horizontal and vertical lengths of the elastic bungee cord 153 when the tension is maximum.
[0059] like Figure 4 , Figure 4 This is a schematic structural diagram of a fourth embodiment of an adaptively adjustable shoulder strap in the present invention. In some implementations, the driving device of the left and right shoulder flexible belts of the power mechanism may also adopt a push-pull driving structure.
[0060] In some embodiments, the strap system 150 also includes a fixing plate 151, which is arranged in the vertical direction of the hollow connecting belt, and a power mechanism is arranged on the fixing plate 151. The driving device 154 tightens or loosens the left and right shoulder flexible straps 152 and the waist flexible strap 152 by winding the elastic elastic rope 153.
[0061] Hollow connecting belts are mainly used for product beauty, such as Figure 3 , Figure 3This is a schematic structural diagram of the third embodiment of an adaptively adjustable shoulder strap in the present invention, in which a fixing plate 151 and other functional components such as a control button 111, a battery 200, a circuit system, a driving device 154, and a transmission device on the fixing plate 151 are arranged. For operational needs, the control button 111 can be arranged on the front side of the human body of the product strap system 150.
[0062] In some embodiments, the driving device 154 includes a first reel 1542, a driving gear 1543, a second reel 1544 and a plurality of pulleys 1545. One end of the first reel 1542 is directly connected to the motor 1541 or connected through a transmission gear, and the other end is gear-connected to the second reel 1544. The plurality of pulleys 1545 are respectively arranged at the connection positions of the left and right shoulder flexible belts 152, the waist flexible belt 152 and the fixed plate 151. The elastic bungee cord 153 passes through the pulley 1545 and is wound around the first reel 1542 and the second reel 1544.
[0063] An adaptive strap adjustment method, such as Figure 6 , Figure 6 This is a schematic diagram of a first embodiment of an adaptive shoulder strap adjustment method in the present invention, comprising:
[0064] S1, detecting the left and right tilt angle of the user's shoulder or the shoulder-back angle;
[0065] It should be noted that before formally correcting the user's posture, it is necessary to first initialize to obtain the best tension threshold. A tension value that is too small is not conducive to auxiliary correction, and a tension value that is too large will make the user feel uncomfortable. Therefore, it is very important to obtain the best tension value threshold. In this application, the adaptation can not only adjust the tension value in time for auxiliary correction, but also learn according to the user's physical condition to obtain the best tension value threshold.
[0066] Preferably, if Figure 7 , Figure 7 This is a schematic diagram of a second embodiment of an adaptive strap adjustment method in the present invention, wherein initialization includes the following steps:
[0067] S4, obtaining the maximum tension value acceptable to the user when the user corrects his posture in different working modes;
[0068] S5. Set the tension value as the tension threshold of the corresponding mode.
[0069] The posture sensing module 130 monitors the user's front and back and left and right tilt angles in real time. The front and back tilt angle can be the angle between the shoulders and back, and an increase in the angle indicates that the user is sitting with a hunched back. The left and right tilt angles can be the user's left and right tilt posture, or the user's high and low shoulder posture, which can be monitored by the posture sensing module 130 and output to the control module 110 for evaluation and judgment.
[0070] S2. If the left-right inclination angle of the user's shoulder or the shoulder-back angle exceeds the threshold, the power mechanism tightens the transverse elastic elastic rope 153 or the vertical elastic elastic rope 153 to the maximum tension value, and guides the user to correct the posture through the tension;
[0071] S3. If the left-right inclination angle of the user's shoulder or the shoulder-back angle exceeds a threshold, the adaptively adjusted tension value continues to exceed a specified time, the power mechanism is reversed, and the tension of the elastic bungee cord 153 is reduced to zero.
[0072] The adaptive adjustment module 140 directly controls the strap system 150 to automatically adjust the tension of the elastic bungee 153 to assist in correcting the user's posture. The specific user first selects a working mode, first, selects "sitting mode" or "standing mode", presses the "left and right locking" key, controls the motor 1541 of the left and right elastic bungee 153 of the shoulder to rotate and slowly tighten until the user feels that the tension is appropriate, releases the "left and right locking" key, and at this time the tension detection module 120 records the tension value of the left and right elastic bungee 153 and sets it as the left and right tension threshold.
[0073] Then, press the "up and down locking" button to control the motor 1541 of the upper and lower elastic bungee cords 153 on the back to rotate and start to slowly tighten until the user feels the tension is appropriate, and release the "up and down locking" button. At this time, the tension detection module 120 records the tension values of the upper and lower elastic bungee cords 153 and sets them as upper and lower tension thresholds.
[0074] The user posture perception module 130 monitors the angles of the user's left and right shoulders in real time. For example, when the line connecting the two shoulders of the user exceeds a certain angle of the horizontal line, such as 5 degrees, the adaptive adjustment module 140 controls the strap system 150 to start the motor 1541 to tighten the left and right elastic ropes 153 to the threshold value, maintain the maximum tension for 10 seconds, and if the posture does not change, loosen the straps.
[0075] The user posture sensing module 130 monitors the angle of the upper and lower shoulder of the user in real time. When the user hunches over a certain angle, such as 5 degrees, the adaptive adjustment module 140 controls the strap system 150 to start the motor 1541 to tighten the upper and lower elastic ropes 153 to the threshold value, and maintain the maximum tension for 10 seconds. If the posture does not change, the strap is loosened. If the body posture is not correct again, the motor 1541 is started again to correct it.
[0076] Preferably, the adjustment method further comprises the step of relaxing mode adjustment:
[0077] S6. The user selects the relaxation mode, the power mechanism is reset and stops working, and the tension of the elastic elastic rope 153 is reduced to the minimum value. If the user wants to relax for a short time and does not use the strap correction, the button is pressed to select the relaxation mode. At this time, the motor 1541 does not work, and the strap tension is extremely small, 0-5N, and the user can hardly feel the tension of the strap.
[0078] Preferably, if Figure 8 , Figure 8 Schematic diagram of a third embodiment of an adaptive strap adjustment method in the present invention; step S3 includes sub-steps:
[0079] S31. If the user corrects the posture and adaptively adjusts the tension to the maximum value for more than a specified time, the power mechanism reverses and the tension of the elastic bungee cord 153 is reduced to zero. S32. If the user maintains the posture unchanged for more than a specified time, the power mechanism reverses and the tension of the elastic bungee cord 153 is reduced to zero.
[0080] After obtaining the best threshold, correction is performed according to the user's selected mode. When it is detected that the user's posture is not correct, the adaptive adjustment module 140 controls the strap system 150 to increase the tension of the front, back, left, and right elastic ropes 153 to assist in correction. After a certain period of time, such as 10 seconds, after the user corrects the posture, the motor 1541 of the strap system 150 automatically rotates in the reverse direction to loosen the elastic rope 153 to prevent the user from feeling uncomfortable due to long-term high tension.
[0081] An adaptively adjustable shoulder strap and adjustment method of the present invention are implemented. The posture sensing module 130 and the tension detection module 120 set can monitor the left and right inclination angles of the user's shoulders and the shoulder-back angle in real time. When the body posture inclination exceeds the threshold, the adaptive adjustment module 140 adjusts the tension to the maximum tension value threshold of the corresponding mode according to the instruction of the control module 110 to remind the user. More importantly, the tension value is used to guide the user to correct the posture. After the user corrects to the corresponding posture, the tension value gradually recovers to the tension value threshold corresponding to the mode, and then the correction is completed. Adaptive adjustment is used to determine the tension value and posture angle of the correct posture, and the tension is used to assist the user in correction. The problem of the prior art that only reminders are provided but the effectiveness and poor adaptability of assisting the user to correct to the correct posture are solved. The myopia, uneven shoulders, scoliosis of school-age adolescents, and cervical and lumbar diseases of people who sit for a long time can also be prevented.
[0082] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
