Description

Fishing reel with electronic brake system

Technical Field

The utility model relates to a fishing vessel, especially relate to a fishing vessel with electronic brake system.

Background

Luya has become more and more accepted by fishing friends in recent years as the most environmentally friendly form of fishing. The traditional water drop wheel has the defects of difficult control of throwing and easy line explosion, and the throwing angle and force can be controlled only by one-time practice of a user. In order to solve this problem, the existing solutions at present are to add centrifugal brakes and magnetic brakes.

The centrifugal brake depends on the friction between the brake beans and the brake disc, the brake force is adjusted by adjusting the number of the working brake beans, and the problems of brake bean abrasion, positive correlation between the brake force and the speed of the line cup, non-linearity of the brake force and the like exist.

The magnetic brake adjusts the braking force by adjusting the permanent magnet and the wire cup, and the faster the rotating speed of the wire cup is, the larger the braking force is. The brake is also dependent on the magnitude of the magnetic field of the permanent magnet. The adjustment of the braking force is limited and the magnetic field of the permanent magnet is large. The adjustment range is smaller.

Chinese patent publication No. CN110432236A discloses a braking device for a dual-bearing reel, which includes a spool braking portion and a spool control portion. The spool braking section brakes the spool by electromagnetic induction in the process of releasing the fishing line. The spool control unit is configured to be able to control the braking force of the spool braking unit by on/off controlling the current generated by the electromagnetic induction in a predetermined 1 st cycle (TP1) and a predetermined 2 nd cycle (TP 2). The bobbin control section has a period changing section. The period changing part changes the 1 st period (TP1) for the spool braking to the 2 nd period (TP2) for the spool braking. Accordingly, the braking force can be stably applied to the spool. However, the scheme has a complex structure and complex technology, has large interference on the fishing reel in the speed judgment process, and still has problems in the actual use process.

Disclosure of Invention

To the technical problem, the utility model provides a take electronic brake system's fishing vessel solves the problem of the easy fried line of fishing vessel.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a fishing reel with an electronic brake system comprises a line cup, a permanent magnet, a brake coil, a line cup rotating shaft, a speed sensor and a circuit board.
