Description

TECHNICAL FIELD

[0002] The magnetic brake system is a kind of line cup rotating speed control technology widely used in modern fishing reel.The basic principle is that when the line cup rotates, it cuts the static magnetic field generated by the fixed magnet, thereby generating eddy current in the line cup, and the eddy current generates a braking force that interacts with the original magnetic field and hinders the rotation of the line cup.The size of the brake force mainly depends on the distance between the magnet and the line cup and the effective area of the line cup cutting magnetic induction lines.

[0003] Currently, the mainstream magnetic brake mechanism is of "preset" type.The angler needs to manually drive the entire magnet assembly to move axially before casting, to adjust its depth of rotation into the reel, and thereby change the area of the line cup cutting magnetic induction lines, to preset a fixed brake force level.

[0004] The traditional magnetic brake mechanism cannot respond to the dynamic changes of the line cup rotating speed during casting.In the initial stage of casting, the line cup rotating speed reaches a peak instantaneously, at which time the maximum brake force is needed to suppress the line explosion.Subsequently, as the flight speed of the dummy bait decays due to air resistance, the line cup rotating speed also decreases, and the required brake force should also be reduced accordingly to pursue a longer distance.The fixed preset brake force cannot meet this dynamic requirement: if the preset force is too large, the casting distance will be severely sacrificed;If the preset force is too small, the initial stage of casting will be extremely unstable and prone to line explosion.
