Description

Technical Field

[0001] This invention relates to the field of football training equipment technology, specifically to an easily adjustable football training launcher. Background Technology

[0002] A football training launcher is an electric device that can automatically and continuously launch a football to a designated location. It can simulate various scenarios such as passing, shooting, high balls, and ground balls, helping players conduct extensive repetitive technical training without teammates. Its core principle is to clamp and launch the football using two high-speed rotating friction wheels. For example, Chinese utility model application CN213491885U discloses a football shooting practice device, including a moving vehicle with a passing and shooting practice structure mounted on it. This structure includes a mounting base, a football delivery basket, a ball hopper, a delivery track, a movable hinge, an angle adjustment seat, an adjustment rod, a pair of motor mounting chambers, a pair of rotary motors, a pair of bearings, a pair of rotating shafts, a pair of launching friction wheels, and an adjustment controller. However, current football launchers have the following shortcomings in terms of adjustment: The soccer launcher has an adjustment function to simulate different types of launch methods. Current adjustment structures mainly have two aspects: one is adjusting the launch position's elevation angle, which adjusts the angle at which the soccer ball is launched; the other is changing the launch effect by adjusting the rotation speed of the two friction wheels. However, the adjustment has the following drawbacks: First, when adjusting the elevation angle, the ball delivery channel also adjusts. The ball delivery channel is usually inclined, relying on gravity to deliver the ball, but adjusting the elevation angle changes the inclination of the delivery channel, leading to poor ball delivery and the risk of the ball getting stuck. Current friction wheel adjustment is limited to adjusting the rotation speed or creating a speed difference between the two friction wheels to change the launch effect, but it cannot adjust the angle between the friction wheels in a variety of ways. This results in an incomplete adjustment of the launch effect; for example, it cannot apply topspin or backspin to the soccer ball.

[0003] Therefore, we propose an easily adjustable football training launcher to solve the above problems. Summary of the Invention
