Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sporting goods, in particular to an intelligent football leg protection plate. TECHNICAL BACKGROUND

[0002] Leg guards generally refer to shin guards used in football. There are also leg guards used in ice hockey, hockey, and other sports. Leg guards are used to protect the calf (with the development of technology, some leg guards can also protect the ankle), so they are also called shin guards. Due to the highly confrontational nature of football games, it is very common for players to be kicked in the calf. Physically, leg guards distribute and dampen the pressure and momentum exerted on the calf to protect the player. The leg guard plate is generally a rigid plate that can distribute the forces exerted on the opposing leg and shoe.In addition, the gap between the leg guards and the legs can play a buffering role, and the skin and flesh between the leg bones and the leg guards also play a buffering role to prevent fractures. However, existing leg guards still have the following shortcomings when used: Conventional soccer shin guards have a single function, providing only physical protection and failing to quantify athletes' athletic performance (e.g., endurance, agility, acceleration, etc.). Existing motion monitoring devices (e.g., armbands and heart rate monitors) cannot accurately capture lower extremity motion data, and their separate design from the shin guards compromises comfort. The two cannot be effectively combined, causing serious problems for users. CONTENT OF THIS APPLICATION
