The present disclosure relates to a swimming aid. The swimming auxiliary apparatus comprises: a positioning plate formed as a curved surface; The binding part is configured as a flexible structure, and one end of the binding part is fixedly connected to one side of the positioning plate, and the other end of the binding part is removably connected to the other side of the positioning plate, so that when both ends of the binding part are connected to both sides of the positioning plate, it can be bound to the body; The swimming fin piece is rotatably connected to the positioning plate, and the swimming fin piece has a light and thin unfolding surface to slide the water; One end of the elastic reset part is connected to the positioning plate, and the other end is connected to the swimming fin part; When the water resistance of the expanded surface when it moves the water body is greater than the critical value, the elastic reset part is compressed and the swimming fin part deflects; When the water resistance of the unfolding surface is less than the critical value, the elastic reset piece can extend to help the fin swimmer reset. Therefore, the range and mode of activity of human body during swimming are improved, and the energy conversion rate is improved. Energy conversion rate. Energy conversion rate< br/>

一种游泳辅助器具
[0001]本公开涉及游泳辅助装置
,具体地,涉及一种游泳辅助器具。
技术介绍
[0002]游泳,即我们的手、臂和腿推水时,水同时以大小相等的反作用力推进我们前进。水的密度大约是空气的1000倍。不像跑步、骑自行车或者其它常见的人类运动形式可以将肌肉的大部分能量转换成前进运动,我们游泳时几乎要消耗90%多的能量去克服液体的阻力。
[0003]流体动力学告诉我们,游泳运动效率取决于二个基本因素,即我们施加的推进力和我们遭遇到的阻力或者是障碍力。人们为了提高游泳运动效率,常使用例如划水掌、手蹼、脚蹼等现有的游泳辅助器具来增加游泳者肢体划水面积,进而提高能量转换率。但划水掌、手蹼会妨碍佩戴者手掌的抓取,脚蹼会妨碍佩戴者行走,使得游泳者的活动方式和活动范围受限。
[0004]对此,针对现有技术中划水掌、手蹼、脚蹼等器材影响游泳者肢体基本功能正常使用的问题,还需要提出一种更为合理的技术方案,以解决当前的技术问题。
