Drag reduction sports helmet based on micro-jet technology and manufacturing method thereof

Abstract

The invention provides a drag reduction sports helmet based on a micro-jet technology and a manufacturing method thereof, relates to the technical field of sports equipment, and solves the technical problems that the continuous lifting space for reducing wind resistance through aerodynamic configuration optimization of an existing sports helmet is not large, and the drag reduction effect is relatively limited in high-speed movement of movement posture adjustment. The drag reduction sports helmet comprises a helmet body, a plurality of micro-jet holes are formed in the rear part of the helmet body. The micro-jet holes penetrate through the helmet body and are uniformly distributed. The micro-jet holes comprise a first micro-jet hole and a second micro-jet hole. The first micro-jet holes areformed in the symmetric line of the helmet body. The second micro-jet holes are evenly distributed in the two sides of the symmetric line. According to an existing sports helmet, the wind resistanceis reduced through aerodynamic configuration optimization, the effect of reducing the air resistance is more obvious, and the sports helmet is particularly suitable for reducing the air resistance inhigh-speed movement of movement posture adjustment.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a drag-reducing sports helmet based on micro-fluid technology and a manufacturing method thereof. Background technique [0002] During sports such as skiing, skating, roller skating, and cycling, athletes not only have to overcome the frictional resistance with the support surface, but the proportion of air resistance in the total resistance continues to increase as the speed of movement continues to increase. Research shows that wind resistance energy consumption accounts for about 20%-25% in cross-country skiing, about 40%-80% in downhill downhill, and as high as 80% in short track speed skating and speed skating events. , For ski jumping, more than 90% of the energy is used to overcome air resistance. [0003] As the necessary sports equipment for the above sports, the improvement of the aerodynamic performance of the helmet will help to improve the performance of co...
