Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and more specifically, to an enemy-catching evaluation system based on an electronic sandbag and its training method. Background Art

[0002] The enemy-catching evaluation system is used in conjunction with other data analysis instruments through an electronic sandbag for enemy-catching training and assessment. The enemy-catching evaluation system has functions of collecting hitting force and hitting times, can set effective hitting force values and assessment time, can divide areas and statistically analyze the maximum and effective hitting force values within each specified effective time, can view historical scores, and supports the export and printing of score data.

[0003] Currently, for the electronic sandbags on the market, their upper parts are fixed and hung on a sandbag support through hanging parts. To prevent the sandbag from shaking when being hit, the bottom of the electronic sandbag is also fixed to the bottom of the sandbag support through several pull ropes to improve the detection accuracy of the force sensor on the electronic sandbag. There are also some manufacturers who, in order to meet the training needs of trainers of different heights, such as a multi-functional sandbag hanging device disclosed in a Chinese invention patent with the application publication number CN 111530049A, have set up a base, a column and a lifting drive mechanism to drive the sandbag support to move up and down.

[0004] However, most of the inner linings of existing electronic sandbags are in a cylindrical structure and are evenly filled with fillers, such as mixtures of sand, cotton yarn, etc., that is, the hardness of each part on the surface of the sandbag is the same. However, for the beginner stage and the proficient stage, the hardness of the sandbag that can be adapted is different. If sandbags with the same standard hardness are used, the hardness is too high, and beginners may be easily injured; if the hardness is relatively low, the required training intensity may not be achieved in the proficient stage. In addition, since different actions such as punching and kicking by the trainer during training act on different parts of the sandbag respectively, and the acting forces of different actions on the sandbag are also different, using sandbags with the same standard hardness will also result in problems such as injury or failure to meet the training intensity requirements. For this reason, we provide an enemy-catching evaluation system based on an electronic sandbag and its training method. Summary of the Invention
