Description

Technical Field

[0001] The present invention relates to the field of measuring human body movement, and in particular to a wearable device for evaluating body state based on a walking sensor. Background Art

[0002] In the prior art, in order to evaluate a person's physical state during walking, it is usually necessary to wear a wearable device with a flexible sensor. The sensors (angle sensor, gyroscope sensor, acceleration sensor, etc.) in the wearable device monitor the user's physical data (motion data) during walking, so as to judge and evaluate the user's physical state. The detection of the ankle joint is to detect the activity angle of the ankle during walking through the sensor. When the angle exceeds the normal activity angle, the sensor can make a judgment, thereby alarming the user to remind him of adverse conditions such as ankle injury or inflammation. The existing wearable device with a flexible sensor is fixed at the ankle joint position by a strap, and the sensor obtains data while the user is running or walking. When facing the colder scenes in winter, in order to resist the cold, close-fitting clothes will be worn. After the user ties the wearable device to the leg and then rolls down the trouser legs, the wearable device on the leg is squeezed by the trouser legs, which will cause the leg to tighten, thereby causing discomfort to the user.

[0003] At the same time, in summer when the temperature is high, the air permeability between the wearable device and the legs is poor, which causes sweat to accumulate in this area and causes discomfort to the user. The existing method uses sweat-absorbent materials to absorb sweat. However, as the user exercises, the sweat absorbed by the sweat-absorbent material is easily squeezed and re-overflows, causing the sweat to re-attach to the legs. Summary of the invention

[0004] In order to overcome the disadvantage that the existing wearable devices are easily squeezed by trouser legs and cause the legs to be tightened when detecting body data, causing discomfort to the user, the present invention provides a wearable device for evaluating body status based on a walking sensor.

[0005] The technical solution of the present invention is: a wearable device for evaluating physical status based on a walking sensor, comprising a loop, a card block and a first pull rope; a plurality of card blocks are arranged on the loop; a plurality of first pull ropes are sleeved inside the loop; each first pull rope is clamped with an adjacent card block; it also comprises a supporting ring, a second pull rope and a shield; a shield is slidably connected inside the loop to prevent the user's legs from being exposed, and the shield is made of elastic fabric; a supporting ring for supporting trouser legs is installed on the shield, and the loop and the supporting ring are both made of flexible materials; a second pull rope is sleeved inside the supporting ring.

[0006] More preferably, the supporting ring is provided with a wrapping portion for wrapping the trouser legs.

[0007] More preferably, the sleeve ring, the supporting ring and the baffle cover may be filled with thermal insulation cotton.

[0008] More preferably, the upper side of the supporting ring is arranged with the middle portion tilted downward.

[0009] More preferably, it further comprises a limit strip; a plurality of limit strips for reducing the contact area between the collar and the leg are fixedly connected to the inner side surface of the collar; and a plurality of mounting parts are arranged inside the collar.

[0010] More preferably, each limiting strip is made of rubber.

[0011] More preferably, it also includes an air bag; the lower side of the ring is connected to the air bag to provide cushioning and protection for rehabilitation training patients.

[0012] More preferably, it also includes a first unidirectional membrane, a second unidirectional membrane and an elastic member; a plurality of first unidirectional membranes for improving the heat dissipation effect are fixedly connected to the upper side of the airbag, and each of the first unidirectional membranes is opened upward; a plurality of second unidirectional membranes are fixedly connected to the lower side of the airbag, and each of the second unidirectional membranes is opened downward; and a plurality of elastic members are fixedly connected to the inside of the airbag.

[0013] More preferably, the airbag is detachably connected to the collar.

[0014] More preferably, the airbag is provided with a plurality of limiting rings to ensure normal exhaust and intake; each of the first one-way membrane and the second one-way membrane is located in an adjacent limiting ring.

[0015] The beneficial effects of the present invention are as follows: the present invention realizes that the trouser legs are pulled up by the supporting ring, and then the second draw cord is pulled to shrink the supporting ring, so that the trouser legs cannot go over the supporting ring and cover the collar after being rolled up, thereby preventing the collar from being squeezed and tightened by the trouser legs; The limit strip is in contact with the leg, so that there is a certain gap between the collar and the leg, reducing the contact area between the device and the leg, which is convenient for the autonomous discharge of sweat; By adding an airbag, a first one-way membrane, a second one-way membrane and an elastic member, the airbag is continuously squeezed and rebounded to generate airflow when the user walks, thereby providing buffer protection and improving the heat dissipation effect.

DETAILED DESCRIPTION

[0018] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0019] Example 1 like Figure 1-Figure 4 As shown, a wearable device for evaluating body status based on a walking sensor includes a collar 1, a block 2 and a first pull rope 3; the collar 1 is equipped with an angle sensor, an acceleration sensor and a gyroscope sensor; two blocks 2 are arranged on the collar 1; two first pull ropes 3 are sleeved in the collar 1; each first pull rope 3 is clamped with an adjacent block 2; It also includes a supporting ring 4, a second pull rope 5 and a shield 6; the shield 6 is slidably connected inside the ring 1, and the shield 6 is made of elastic fabric; the supporting ring 4 is installed on the shield 6, and the ring 1 and the supporting ring 4 are both made of flexible materials, such as silicone rubber and elastic fabric; the second pull rope 5 is sleeved inside the supporting ring 4.

[0020] The supporting ring 4 is provided with a wrapping portion 4001 .

[0021] The sleeve ring 1, the supporting ring 4 and the baffle 6 may be filled with heat-insulating cotton.

[0022] The upper side of the supporting ring 4 is arranged with the middle portion tilted downward.

[0023] Before using the device, the user first puts the loop 1 with the angle sensor, acceleration sensor and gyroscope sensor on the ankle, then presses the front and rear sides of the card block 2 to make the card block 2 loosen the first pull rope 3, and then the user pulls out the first pull rope 3 to shrink the loop 1 and make the loop 1 fit to the user's leg, and finally loosens the card block 2 to clamp the first pull rope 3, and then uses the angle sensor, acceleration sensor and gyroscope sensor to detect the activity angle and ankle joint activity stability of the user's ankle joint during walking, and judges whether the user's ankle joint has a large activity angle. In order to improve the accuracy of the angle sensor, acceleration sensor and gyroscope sensor, the loop 1 usually needs to be fitted on the ankle.

[0024] In winter, when facing the cold scene, close-fitting clothes are worn to resist the cold. After the user puts the ring 1 on the leg, the trouser leg is usually covered on the ring 1, which causes the ring 1 originally fitting comfortably on the leg to be squeezed by the trouser leg, causing the leg to be tightened, thereby causing discomfort to the user. Therefore, before using the present invention, after putting the ring 1 on the leg, the user holds the supporting ring 4 and pulls it up, so that the trouser leg is rolled up under the support of the supporting ring 4. Then, when the trouser leg is pulled up, the trouser leg is pulled up. After rolling up to a certain height, the user pulls the second drawstring 5 to shrink the support ring 4, thereby making the support ring 4 fit the leg and fix it, and finally pulls the first drawstring 3 to shrink the ring 1. In this way, the trouser legs can no longer pass over the support ring 4 and cover the ring 1 after being rolled up, preventing the ring 1 from being squeezed and tightened by the trouser legs. Furthermore, in order to prevent cold wind from entering the leg position from between the support ring 4 and the trouser legs, the wrapping part 4001 is also shrunk synchronously during the process of shrinking the support ring 4 using the second drawstring 5. At the same time, since the upper side of the supporting ring 4 is arranged to be inclined downward in the middle, when the trouser legs contact the upper side of the supporting ring 4, the trouser legs are gradually brought closer to the legs under the guidance of the inclined upper side of the supporting ring 4, and then the supporting ring 4 is contracted by the second drawstring 5, so that the trouser legs can fit closely to the legs under the action of the wrapping part 4001, thereby preventing cold wind from blowing towards the user's legs and causing discomfort. At the same time, when the user pulls the supporting ring 4 upward, the supporting ring 4 also pulls out the blocking cover 6 synchronously, so that the supporting ring 4 and The ring 1 is blocked by the shield 6, which also prevents the leg area between the supporting ring 4 and the ring 1 from being directly blown by cold wind after the trouser legs are rolled up. At the same time, the ring 1, the supporting ring 4 and the shield 6 are filled with thermal insulation cotton, so that the ring 1, the supporting ring 4 and the shield 6 can be used as thermal insulation clothing to provide warmth for the parts of the user's legs that are not blocked by clothes. It should be noted that if the present invention is used in summer or hot weather, the ring 1, the supporting ring 4 and the shield 6 of the present invention do not need to be filled with thermal insulation cotton.

[0025] Example 2 On the basis of Example 1, Figure 5-Figure 7As shown, it also includes a limit strip 101; a plurality of limit strips 101 are fixedly connected to the inner side of the collar 1; a plurality of mounting portions 1001 are arranged inside the collar 1, and the mounting portions 1001 are used to mount an angle sensor, an acceleration sensor and a gyroscope sensor.

[0026] Each limiting strip 101 is made of rubber material, so that the limiting strip 101 can be deformed after being fitted to the leg, thereby improving the comfort of the user during use.

[0027] It also includes an air bag 103; the lower side of the collar 1 is connected to the air bag 103.

[0028] It also includes a first one-way membrane 102, a second one-way membrane 104 and an elastic member 105; a plurality of first one-way membranes 102 are fixedly connected to the upper side of the airbag 103, and each of the first one-way membranes 102 is opened upward; a plurality of second one-way membranes 104 are fixedly connected to the lower side of the airbag 103, and each of the second one-way membranes 104 is opened downward; a plurality of elastic members 105 are fixedly connected inside the airbag 103, and the elastic members 105 are springs.

[0029] The airbag 103 is detachably connected to the collar 1 .

[0030] A plurality of limiting rings 10301 are provided on the airbag 103 ; each of the first one-way membrane 102 and the second one-way membrane 104 is located in an adjacent limiting ring 10301 .

[0031] In the hot summer, when the user fits the sleeve 1 on the leg and then exercises, the position where the sleeve 1 fits the leg is not ventilated, which causes the user's legs to sweat easily, and the sweat is likely to remain between the sleeve 1 and the leg, causing discomfort in the user's legs. In the prior art, a material with a sweat-absorbing function is fitted to the leg, but after the sweat-absorbing material is saturated, the sweat absorbed by the sweat-absorbing material is likely to be squeezed and overflowed again during the user's exercise, causing the sweat to re-attach to the leg. Therefore, in the process of fitting the sleeve 1 to the user's leg, the limiting strip 101 is used to prevent the user from sweating. The legs are in contact and fit so that there is a certain gap between the ring 1 and the legs, reducing the contact area between the device and the legs and facilitating the autonomous discharge of sweat. At the same time, in order to ensure that the angle sensor, acceleration sensor and gyroscope sensor are in contact with the skin of the legs, the angle sensor, acceleration sensor and gyroscope sensor are respectively placed on the corresponding mounting parts 1001. Since the side of the mounting part 1001 facing the leg can be fitted on the user's leg like the limit strip 101, the angle sensor, acceleration sensor and gyroscope sensor are still in contact with the skin surface for detection.

[0032] It is also considered that, in the process of the user who needs rehabilitation training using the sleeve 1, in order to avoid the user's ankle from being injured when the user is not fully recovered, the airbag 103 can be clamped on the lower side of the sleeve 1 so that the airbag 103 is located between the ankle and the shoe. It should be noted that: the lower side of the airbag 103 fits with the shoe worn by the user. During the user's exercise, the angle between the sole of the foot and the calf changes, so that the airbag 103 is continuously squeezed during the change of the angle. During the user's walking, the shoe is squeezed by the airbag 103, so that the airbag 103 shrinks. In this process, the user needs to overcome the shrinkage of the airbag 103 to walk, thereby limiting the range of motion between the user's ankle and the sole of the foot, and avoiding the user's unrecovered ankle from being injured due to excessive range of motion. When the airbag 103 is continuously squeezed during the change of the angle between the ankle and the sole of the foot, the elastic member 105 is squeezed and shrunk, and at the same time, the first unidirectional membrane 102 is opened, so that the gas in the airbag 103 is blown to the inside of the sleeve 1. Since there is a certain gap between the sleeve 1 and the leg at this time, the sleeve 1 and the leg are separated. There is airflow between the legs, thereby dissipating heat between the device and the legs, reducing sweat adhering to the legs or the device, and improving the comfort of the device during use. When the airbag 103 loses its compression, the elastic member 105 inside the airbag 103 rebounds, thereby driving the airbag 103 to reset and expand. At this time, the second unidirectional membrane 104 opens and the first unidirectional membrane 102 closes, replenishing gas to the airbag 103. In this way, the airbag 103 is frequently squeezed during the user's walking, so that there is always airflow between the ring 1 and the leg, thereby Cooperate with the limit strip 101 to improve the heat dissipation effect; it should be noted that: since the limit ring 10301 is provided on the air bag 103, that is, when the air bag 103 is squeezed and contracted by the leg, under the restriction of the limit ring 10301, the second one-way membrane 104 and the first one-way membrane 102 are guaranteed to open normally for exhaust and air intake, thereby ensuring the auxiliary heat dissipation work of the air bag 103; in addition, when the present invention is used for the user to detect the swing angle of the ankle when running, the air bag 103 can also be clamped on the lower side of the ring 1 for buffering protection and improving the heat dissipation effect.
