Specifically, for example, as shown in FIG. 6 , one end of the elastic cord 110 is connected to the pull ring 90 through a motion sensing detection device 10 , and the other end of the elastic cord 110 is connected to the pull ring 90 through a connecting component 70 . Therefore, only A motion sensing detection device 10 needs to be provided to detect the tensile force data, thereby saving costs. Wherein, the connecting component 70 is configured as a connecting component suitable for fixing the elastic cord 110 and the pull ring 90 together, which can be hard, soft or other materials, and can be an integral molding structure or a detachable structure Wait. For example, as shown in FIG. 7 , the two ends of the elastic cord 110 are connected to the two pull rings 90 correspondingly through the two motion sensing detection devices 10 . Therefore, by arranging the two motion sensing detection devices 10 , the tensile force can be detected more accurately In addition, when one motion sensing detection device 10 fails, the other motion sensing detection device 10 can also detect the tensile force data normally, thereby improving the reliability of the smart tensioner 100 .

In an embodiment of the present application, as shown in FIG. 2 , FIG. 8 and FIG. 15 , the intelligent tensioner 100 further includes: a fixed pulley assembly 130 and a regulator 140 .

As shown in FIGS. 9-11 , the regulator 140 includes a housing 141 and a winding post 142 , and the winding post 142 is located in the housing 141 . One end of the elastic cord 110 is provided with the motion sensing detection device 10 , the other end penetrates into the housing 141 , and is wound around the winding post 142 , and then passes through the housing 141 , and the other end of the elastic cord 110 bypasses the fixed pulley assembly After 130, it is fixedly connected to the housing 141, and the winding path of the elastic cord 110 is shown by the arrow in FIG. 9 . It should be noted that after the other end of the elastic cord 110 is passed out of the housing 141, it passes through the fixed pulley assembly 130, and is then connected to the housing 141, so that the length of this part of the elastic cord 110 can be automatically adjusted, so as to balance the fixed pulley assembly 130. The length of the bungee cords 110 on both sides of the pulley assembly 130 .

It can be understood that the adjuster 140 can divide the elastic cord 110 into two parts, one of which is from one end of the elastic cord 110 to the adjuster 140, and the motion sensing detection device 10 is provided on this part, which can be used by the user during training. The pulling motion sensing detection device 10 exerts a pulling force on the elastic cord 110, and the tension sensor 124 in the motion sensing detection device 10 can detect the magnitude of the pulling force; the other part is from the other end of the elastic cord 110 to the adjuster 140, at On this part, the elastic rope 110 goes around the fixed pulley assembly 130 , and the user can apply tension to the elastic rope 110 by pulling the fixed pulley assembly 130 during training.

When the smart tensioner 100 is used, the two parts of the elastic cord 110 are respectively subjected to tension. Under the action of the tension, the elastic cord 110 is wound around the winding post 142 , and the greater the tension, the elastic cord 110 is placed on the winding post 142 The larger the winding force is, the more difficult it is to change the relative position between the elastic cord 110 and the winding post 142 , and the winding post 142 has a positioning effect on the elastic cord 110 at this time. When the smart tension device 100 is in a natural state, the elastic cord 110 is not affected by external force, the elastic cord 110 is wound on the winding post 142 in a natural state, and the elastic cord 110 has no force between the winding posts 142. When a part of the rope 110 is fed into the casing 141 of the adjuster 140, the elastic rope 110 can move relative to the winding post 142. Due to the limited space in the casing 141, driven by the elastic rope 110, another part of the elastic rope 110 can move. A part will be extruded from the casing 141 , so that the distance between the adjuster 140 and one end of the elastic cord 110 can be adjusted, and then the length of the smart tensioner 100 can be adjusted.

Of course, it can also be understood that when the smart tensioner 100 is in a natural state, the elastic cord 110 on one side of the adjuster 140 is exerted force, and the user drives the adjuster 140 to move along the elastic cord 110, and at this time the elastic cord 110 is wound around the wire The column 142 can move, and the length of the elastic cord 110 on one side of the adjuster 140 and the length of the elastic cord 110 on the other side of the adjuster 140 are in a state of change, that is, the overall length of the smart tensioner 100 can be affected at this time. Make adjustments.

Therefore, by setting the adjuster 140 and setting the winding post 142 in the housing 141 of the adjuster 140, the elastic cord 110 is wound on the winding post 142, and when the user sends a part of the elastic cord 110 into the regulator 140 When the elastic cord 110 is inside the housing 141, the elastic cord 110 can move relative to the winding post 142. Due to the limited space in the housing 141, driven by the elastic cord 110, another part of the elastic cord 110 will be extruded from the housing 141. , so that the distance between the adjuster 140 and one end of the elastic cord 110 can be adjusted, and then the length of the intelligent tensioner 100 can be adjusted; when the intelligent tensioner 100 is used, the two parts of the elastic cord 110 are respectively subjected to tension, The greater the pulling force, the greater the winding force of the elastic cord on the winding post, so that the elastic cord 110 can be positioned, thereby meeting the needs of different users and improving the applicability of the product.
