Description

Technical Field

[0001] The utility model relates to the technical field of wearable devices, in particular to a wearable device for collecting upper limb motion data. Background Art

[0002] As the concept of healthy living becomes more and more popular, more and more young people are interested in physical exercise. Exercising the upper and lower limbs, as well as the waist and back muscles, is not only beneficial for health but also helps maintain a good figure. The trapezius muscle, which connects the neck and back, is a particularly popular muscle for fitness enthusiasts. Effective exercise helps maintain an upright spine and reduces the health risks associated with hunching.

[0003] Currently, most fitness enthusiasts use an elastic cord wrapped around their backs to repeatedly open and close their arms, leveraging their arm strength to activate the trapezius muscles. However, due to a lack of standardized movement and a lack of feedback on arm strength, exercisers rely solely on subjective judgment to correct their posture, making it difficult to achieve the desired results. Furthermore, effective feedback on the exercise movements hinders maintaining a standardized posture and can result in counterproductive training. To address this issue, we propose a wearable device for collecting upper limb motion data. Utility Model Content

[0007] As a further solution of the present invention: the inner wall of the back wrap is welded with symmetrical limiting ridges, the length of the limiting ridges is equal to the height of the back wrap, and the width of the limiting ridges is 3cm-5cm. The limiting ridges can maintain the relative position of the back wrap and the user's back to prevent the back wrap from deviating.

[0008] As a further solution of the present invention: the material of the elastic traction belt is high-elastic fiber, and a plurality of tough reinforcing ribs arranged at equal intervals are sewn on one side of the elastic traction belt, which can enhance the fatigue resistance of the elastic traction belt and help extend the service life of the elastic traction belt.
