Description

TECHNICAL FIELD

[0001] The present application relates to the field of measuring human motion, in particular to a wearable device for evaluating body state based on walking sensor. BACKGROUND

[0002] In the prior art, in order to evaluate the body state of a person during walking, a wearable device with a flexible sensor is usually needed, and the sensor (angle sensor, gyroscope sensor and acceleration sensor, etc.) in the wearable device is used to monitor the body data (motion data) of the user during walking, so as to judge and evaluate the body state of the user. The detection of the ankle joint is achieved by detecting 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 prompting the user to take precautions against injury or inflammation, etc. The wearable device with a flexible sensor is fixed on the ankle joint position by a strap, and the sensor obtains data during running or walking of the user. However, when the user is in a cold winter environment, he / she will wear close-fitting clothes to resist the cold. After the wearable device is bound on the leg and the trouser legs are rolled down, the wearable device on the leg is squeezed by the trouser legs, which causes the leg to be tight, thereby causing discomfort to the user.

[0003] Meanwhile, in a high-temperature summer environment, the wearable device has poor air permeability with the leg, which causes sweat to accumulate in this part and causes discomfort to the user. The existing method uses sweat-absorbing materials to absorb sweat. However, during the user's movement, the sweat absorbed by the sweat-absorbing materials is easily squeezed out, which causes the sweat to reattach to the leg. SUMMARY

[0004] In order to overcome the shortcomings that the existing wearable device is easily squeezed by the trouser legs when detecting body data, causing the leg to be tight and causing discomfort to the user, the present application provides a wearable device for evaluating body state based on walking sensor.

[0005] The technical scheme of the present application is: a wearable device for evaluating body state based on walking sensor, comprising a collar, a clamping block and a first pull rope; a plurality of clamping blocks are arranged on the collar; a plurality of first pull ropes are sleeved in the collar; each first pull rope is connected with the adjacent clamping block; further comprising a supporting ring, a second pull rope and a shield; the shield for preventing the user's leg from being exposed is slidably connected in the collar, and the shield is made of elastic cloth material; the supporting ring for supporting the trouser legs is installed on the shield, and the collar and the supporting ring are both made of flexible material; the second pull rope is sleeved in the supporting ring.

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

[0007] More preferably, the collar, the supporting ring and the shield can be filled with thermal cotton.

[0009] More preferably, the device further comprises limiting strips; the inner side of the sleeve ring is fixedly connected with a plurality of limiting strips for reducing the contact area between the sleeve ring and the leg; and the sleeve ring is internally provided with a plurality of mounting portions.

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

[0011] More preferably, the device further comprises an air bag; and the lower side of the sleeve ring is connected with the air bag for providing cushioning and protecting the patient during rehabilitation training.

[0012] More preferably, the device further comprises a first one-way membrane, a second one-way membrane and elastic members; the upper side of the air bag is fixedly connected with a plurality of first one-way membranes for improving the heat dissipation effect, and each first one-way membrane is upwardly open; the lower side of the air bag is fixedly connected with a plurality of second one-way membranes, and each second one-way membrane is downwardly open; and the inside of the air bag is fixedly connected with a plurality of elastic members.

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

[0015] The device has the advantages that the supporting ring is pulled upward, the trouser legs are pulled upward under the support of the supporting ring, the supporting ring is then contracted by pulling the second pull rope, the trouser legs cannot be pulled over the sleeve ring to compress the leg after being pulled up, and the sleeve ring is prevented from being compressed by the trouser legs to tighten the leg.

Detailed Implementation

[0026] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1-4 As shown, a wearable device for assessing body status based on walking sensors includes a collar 1, a locking block 2, and a first pull cord 3; the collar 1 contains an angle sensor, an acceleration sensor, and a gyroscope sensor; two locking blocks 2 are provided on the collar 1; two first pull cords 3 are sleeved inside the collar 1; each first pull cord 3 is engaged with an adjacent locking block 2.

[0029] It also includes a support ring 4, a second pull rope 5, and a cover 6; the cover 6 is slidably connected inside the collar 1, and the cover 6 is made of elastic fabric; the support ring 4 is installed on the cover 6, and both the collar 1 and the support ring 4 are made of flexible materials, such as silicone rubber and elastic fabric; the second pull rope 5 is sleeved inside the support ring 4.

[0030] The support ring 4 is provided with a wrapping part 4001.

[0031] The collar 1, the supporting ring 4, and the baffle 6 can be filled with thermal insulation cotton.

[0032] The upper side of the support ring 4 is designed to slope downwards in the middle.

[0033] Before using the device, the user first puts the sleeve 1 with the angle sensor, acceleration sensor and gyroscope sensor on the ankle, then the user presses the clamping block 2 on both sides, loosens the first pull rope 3, then the user pulls out the first pull rope 3, and then the sleeve 1 is retracted, so that the sleeve 1 is attached to the user's leg, and finally the clamping block 2 is loosened to clamp the first pull rope 3, and then the angle sensor, acceleration sensor and gyroscope sensor are used to detect the activity angle and stability of the ankle joint during walking, to determine whether the user's ankle joint has an excessively large activity angle. In order to improve the accuracy of the angle sensor, acceleration sensor and gyroscope sensor, the sleeve 1 usually needs to be attached to the ankle.

[0034] When facing a cold winter scene, in order to resist the cold, a close-fitting garment is worn, and after the user attaches the sleeve 1 to the leg, the trouser legs are usually covered on the sleeve 1, which will cause the sleeve 1 that is originally comfortably attached to the leg to be squeezed by the trouser legs, causing the leg to be tight, and thus causing the user to be uncomfortable. Therefore, before using the present application, after the sleeve 1 is put on the leg, the user holds the supporting ring 4 and pulls it up, so that the trouser legs are rolled up under the support of the supporting ring 4, then when the trouser legs are rolled up to a certain height, the user pulls the second pull rope 5 to retract the supporting ring 4, and then the supporting ring 4 is attached to the leg for fixation, and finally the first pull rope 3 is pulled to retract the sleeve 1, so that the trouser legs rolled up cannot cover the sleeve 1 beyond the supporting ring 4, preventing the sleeve 1 from being squeezed by the trouser legs and tightening the leg. Further, in order to prevent cold air from flowing into the leg position between the supporting ring 4 and the trouser legs, the second pull rope 5 is used to retract the supporting ring 4, which also synchronously retracts the wrapping part 4001. At the same time, since the upper side of the supporting ring 4 is inclined downward from the middle, when the trouser legs contact the upper side of the supporting ring 4, they are gradually guided to the leg under the inclination of the upper side of the supporting ring 4, and then the second pull rope 5 is used to retract the supporting ring 4, which facilitates the trouser legs to be closely attached to the leg under the action of the wrapping part 4001, preventing cold air from blowing to the user's leg and causing discomfort. At the same time, when the user pulls the supporting ring 4 up, the supporting ring 4 also pulls out the shield 6, so that the supporting ring 4 and the sleeve 1 are shielded by the shield 6, preventing the leg area between the supporting ring 4 and the sleeve 1 from being directly blown by cold air without a shielding area. At the same time, the sleeve 1, the supporting ring 4 and the shield 6 are all filled with thermal cotton, so that the sleeve 1, the supporting ring 4 and the shield 6 can be used as thermal clothing, providing warmth to the part of the user's leg without clothing coverage.

[0035] Example 2

[0036] Based on example 1, as Figures 5-7As shown, it also comprises a limiting strip 101; a plurality of limiting strips 101 are fixed on the inner side of the sleeve ring 1; a plurality of mounting portions 1001 are arranged in the sleeve ring 1, and the mounting portions 1001 are used for mounting the angle sensor, the acceleration sensor and the gyroscope sensor.

[0037] Each limiting strip 101 is made of rubber material, so that the limiting strip 101 can be deformed after being attached to the leg, thereby improving the comfort of the user during use.

[0038] It also comprises an air bag 103; the air bag 103 is connected to the lower side of the sleeve ring 1.

[0039] It also comprises 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 fixed on the upper side of the air bag 103, and each first one-way membrane 102 is upwardly open; a plurality of second one-way membranes 104 are fixed on the lower side of the air bag 103, and each second one-way membrane 104 is downwardly open; a plurality of elastic members 105 are fixed inside the air bag 103, and the elastic member 105 is a spring.

[0040] The air bag 103 is detachably connected with the sleeve ring 1.

[0041] A plurality of limiting rings 10301 are arranged on the air bag 103; each first one-way membrane 102 and second one-way membrane 104 is located in the adjacent limiting ring 10301.

[0042] When the user attaches the sleeve ring 1 to the leg and moves in the hot summer, the position where the sleeve ring 1 is attached to the leg is not breathable, which causes the user's leg to easily sweat, and the sweat is easily left between the sleeve ring 1 and the leg, causing discomfort of the user's leg. The existing way is to attach the sweat-absorbing material to the leg, but after the sweat-absorbing material is saturated, the sweat absorbed by the sweat-absorbing material is easily extruded and re-extruded during the user's movement, causing the sweat to re-attach to the leg. Therefore, in the process of attaching the sleeve ring 1 to the user's leg, the limiting strip 101 is used to contact and attach to the leg, so that there is a gap between the sleeve ring 1 and the leg, which reduces the contact area between the device and the leg, facilitates the self-discharge of sweat, and at the same time, in order to ensure that the angle sensor, the acceleration sensor and the gyroscope sensor are attached to the skin of the leg, the angle sensor, the acceleration sensor and the gyroscope sensor are respectively placed on the corresponding mounting portion 1001. Since the side of the mounting portion 1001 facing the leg is the same as the limiting strip 101, it can be attached to the user's leg, and thus the angle sensor, the acceleration sensor and the gyroscope sensor can still be attached to the skin surface for detection.

[0043] It is also considered that, in the process of using the sleeve ring 1 by the user who needs rehabilitation training, in order to avoid the injury of the ankle of the user in the state of incomplete rehabilitation, the air bag 103 can be clamped on the lower side of the sleeve ring 1, so that the air bag 103 is located between the ankle and the shoe, and it is necessary to note that the lower side of the air bag 103 is in contact with the shoe worn by the user, and in the process of the user's movement, the angle between the sole and the lower leg changes, so that the air bag 103 is continuously extruded in the process of the angle change, and in the process of the user walking, the shoe is extruded by the air bag 103, so that the air bag 103 is contracted, and in this process, the user needs to walk against the contraction of the air bag 103, so as to limit the activity range between the ankle and the sole of the user, so as to avoid the injury of the user's ankle with an excessive activity range, and when the air bag 103 is continuously extruded in the process of the angle change between the ankle and the sole, the elastic member 105 is extruded and contracted, at the same time, the first one-way membrane 102 is opened, so that the gas in the air bag 103 blows to the inside of the sleeve ring 1, and since there is a gap between the sleeve ring 1 and the leg at this time, there is airflow between the sleeve ring 1 and the leg, so as to cool the equipment and the leg, reduce the adhesion of sweat on the leg or the equipment, and improve the comfort of the equipment in the process of use, and when the air bag 103 loses the extrusion, the elastic member 105 in the air bag 103 rebounds, so as to drive the air bag 103 to reset and expand, at this time, the second one-way membrane 104 is opened and the first one-way membrane 102 is closed, so as to supplement the air bag 103 with air, and in this way, the air bag 103 is frequently extruded in the process of walking of the user, so that there is always airflow between the sleeve ring 1 and the leg, so as to improve the cooling effect in cooperation with the limiting strip 101; it should be noted that since the limiting ring 10301 is arranged on the air bag 103, when the air bag 103 is extruded and contracted by the leg, the limiting ring 10301 limits the second one-way membrane 104 and the first one-way membrane 102 to be normally opened and exhausted, so as to ensure the auxiliary cooling work of the air bag 103; in addition, when the present application is used for detecting the swing angle of the ankle of the user during running, the air bag 103 can also be clamped on the lower side of the sleeve ring 1, so as to buffer and protect and improve the cooling effect.

Moreover, it should be understood that those skilled in the art can make various modifications or changes to the present application after reading the content of the present application, and these equivalent forms also fall within the scope defined by the claims of the present application.
