Embodiment Construction

[0018] The following examples serve to illustrate the invention.

[0019] As shown in the specific embodiment shown in Figure 1, a kind of discus for athlete dynamics information testing comprises upper casing 2 and lower casing 9 in the structure, and upper casing 2 and lower casing 9 are made of engineering plastics, three A cross-recessed pan head screw 8 and three hex nuts 7 are distributed on the edge of the upper case 2 at an angle of 120°, and the upper case 2 and the lower case 9 are fastened on both sides of the metal ring 1, and slightly lower On the surface of the upper casing 2 and the lower casing 9. The upper casing 2, the lower casing 9 and the metal ring 1 constitute the cake body of the digitized discus. A cavity is formed between the upper case 2 and the lower case 9, and there is a groove in the center of the inner side of the lower case 9, and a circular circuit board 4 is fixed above the groove, and its center of circle coincides with that of the lower ca...

Abstract

The present invention discloses one kind of discus capable of sensing force. The discus has one hollow discus body comprising one upper casing, one lower casing and one metal ring connecting the upper casing and the lower casing, one circuit board fixed inside the lower casing, one E-type diaphragm connected to the circuit board, weight blocks, and battery. The discus can acquire and quantize the stress data before and during the flying of the discus to reflect the effectiveness of the player' s action, and this makes it possible to raise the throwing technology and the sports level of the player.

Description

technical field [0001] The invention relates to a kind of sports equipment, in particular to a discus used for athlete dynamics information testing, which can acquire the six-dimensional force information of the discus thrower during the throwing process in real time for training guidance. Background technique [0002] With the continuous improvement of the level of sports competition, the demand for equipment performance and types of sports auxiliary training equipment is also increasing. Scientific auxiliary training equipment can provide technical support for sports training, scientific research and teaching, help coaches, researchers and athletes understand the inherent laws of sports, optimize training methods, and improve sports performance. At present, the kinematic parameters of throwing sports at home and abroad are generally measured using a motion capture system. This method sticks a tracker on the part to be measured, and then indirectly obtains the kinematic par...
