Currently, magnetic brake structures for fishing reels typically place magnets near the end of the spool, which requires a component to cut the magnetic induction wire. This inevitably increases the reel's processing cost and weight, and makes it difficult to automatically adjust the braking force according to the spool's rotation speed during casting, making wind knots more likely to occur.

[0016] In order for those skilled in the art to understand the objectives, technical means and advantages of the present invention more clearly, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0017] 1 to 4, which illustrate a first embodiment of a magnetic brake mechanism 1 of the present invention. In the embodiment shown in the drawings, the magnetic brake mechanism 1 includes a spool 10 and a magnetic brake assembly 20 provided on one side of the spool 10. The magnetic brake assembly 20 includes a magnet assembly for generating magnetic induction lines and a centrifugal adjustment assembly 22 for automatically adjusting the distance between the magnet assembly and the inner wall of the spool 10 based on the rotational speed of the spool 10 and adjusting the extent to which the spool 10 cuts off the magnetic induction lines, thereby automatically adjusting the magnitude of the braking force. That is, the magnetic brake mechanism 1 of the present invention achieves the objective of automatically adjusting the magnitude of the braking force by controlling the strength of the magnetic induction lines near the inner wall of the spool 10 as the magnet assembly moves radially toward or away from the inner wall of the spool 10 during rotation of the spool 10, thereby adjusting the extent to which the inner wall of the spool 10 cuts off the magnetic induction lines. From the above, it can be seen that the magnetic brake mechanism 1 of the present invention cuts the magnetic induction line with the inner wall of the spool 10 as it rotates, eliminating the need to provide a component for cutting the magnetic induction line on the end face of the spool 10, thereby reducing weight and processing costs. Moreover, because the distance between the magnet assembly and the inner wall of the spool 10 is adjustable, different braking forces can be applied depending on the rotation speed of the spool 10 during casting, reducing the probability of wind knots and ensuring stable casting. At the same time, it maximizes casting distance, making it particularly suitable for fishing with small bait.

[0018] In some embodiments, the centrifugal adjustment assembly 22 includes a spring 221, and the magnet assembly includes a magnet base 211 and at least one arc-shaped magnet 212 consisting of a plurality of magnets. The magnet base 211 is provided with at least one arc-shaped mounting base 2111 and a slide base 213, each arc-shaped magnet 212 is provided on one slide base 213, and the bottom of the arc-shaped magnet 212 is located within the spool 10. The slide base 213 is movably fitted into the mounting base 2111 via the spring 221 and moves radially under the action of centrifugal force or the elastic force of the spring 221 to adjust the distance between the arc-shaped magnet 212 and the inner wall of the spool 10 when the spool 10 rotates. Preferably, in this embodiment, the slide base 213 is provided with a mounting groove 2132, and the arc-shaped magnet 212 is provided in the mounting groove 2132, and the magnet is a sector magnet, with opposite magnetic properties of two adjacent magnets. When the magnetic brake mechanism 1 of the present invention is incorporated into a reel body, the spool 10 rotates at high speed during casting, causing the arc-shaped magnet 212 to approach the inner wall of the spool 10 in the radial direction, increasing the strength of the magnetic induction line that can be cut by the inner wall of the spool 10 and providing a greater braking force, effectively preventing wind knots caused by the spool 10 rotating too fast. During the later stages of casting, the rotational speed of the spool 10 gradually decreases, and the arc-shaped magnet 212 moves away from the inner wall of the spool 10 under the action of the spring 221, weakening the strength of the magnetic induction line that can be cut by the inner wall of the spool 10, thereby reducing the braking force and improving the casting distance.

[0019] 2 to 4 , in some embodiments, both ends of the sliding base 213 are extended outward and bent to form first limiting plates 2131, and both ends of the mounting base 2111 are correspondingly extended outward to form second limiting plates 2113. The springs 221 are respectively provided between the two first limiting plates 2131 and the mounting base 2111. Thus, the sliding base 213 moves radially under the action of centrifugal force or the elastic force of the springs 221. During the compression of the springs 221, the first limiting plates 2131 abut against the second limiting plates 2113, limiting the position of the sliding base 213 and preventing the sliding base 213 from falling off the mounting base 2111. Preferably, in this embodiment, the centrifugal adjustment assembly 22 further includes a cover plate 222. The cover plate 222 is located on a side of the sliding base 213 closer to the spool 10. The magnet base 211 and the cover plate 222 are fixed together via screws 23. The magnet base 211 is also provided with a limiting block 2112 for limiting the radial movement of the slide base 213 during the extension process of the spring 221, so as to limit the movement of the slide base 213.

[0020] Specifically, in this embodiment, the number of the arc-shaped magnets 212, the mounting bases 2111, and the slide bases 213 is two, the number of the springs 221 is four, and the two mounting bases 2111 are arranged around the center of the magnet base 211. The springs 221 are respectively arranged between both ends of the slide base 213 and both ends of the mounting base 2111. One end of the spring 221 is connected to the first limiting plate 2131 of the slide base 213, and the other end abuts against the mounting base 2111.

[0021] In some embodiments, the magnetic brake mechanism 1 further includes a side cover assembly 30, and the magnetic brake assembly 20 is provided in the side cover assembly 30. The rotation axis 101 of the spool 10 passes through the magnet assembly and is disposed within the side cover assembly 30. Specifically, the side cover assembly 30 includes a side cover main body 31 and a spool base 32 connected to the side cover main body 31, and the rotation axis 101 of the spool 10 passes through the magnet assembly and is disposed within the spool base 32.

[0022] In this embodiment, a portion of the arc-shaped magnet 212 is disposed within the spool 10, and the inner wall of the spool 10 close to the arc-shaped magnet 212 can cut the magnetic induction lines generated by the arc-shaped magnet 212 as the spool 10 rotates, which is advantageous for achieving a lightweight design for the spool 10. Furthermore, the distance between the magnet assembly and the inner wall of the spool 10 is adjustable. During the initial stage of the casting process, when the spool 10 rotates rapidly, the arc-shaped magnet 212 moves radially closer to the inner wall of the spool 10 due to centrifugal force, increasing the strength of the magnetic induction lines that can be cut by the inner wall of the spool 10, providing greater braking force and preventing wind knots. Then, in the later stage of the casting process, as the rotation speed of the spool 10 gradually decreases, the arc-shaped magnet 212 moves away from the inner wall of the spool 10 under the action of the spring 221, and the strength of the magnetic induction line that can be cut by the inner wall of the spool 10 weakens, thereby reducing the braking force and slowing the decrease in the rotation speed of the spool 10, thereby achieving the purpose of improving the casting distance.

[0023] 5 and 6, which illustrate a second embodiment of the magnetic brake mechanism 1 of the present invention. To clearly illustrate the connection relationship between the slide base 213 and the mounting post 2114, the cover plate 222 of the magnetic brake assembly 20 shown in FIG. 6 is not shown. This embodiment differs from the first embodiment in the specific configuration and connection relationship of the centrifugal adjustment assembly 22 and the magnet base 211, but other structures are the same or similar. In this embodiment, the centrifugal adjustment assembly 22 includes a spring 221, and the magnet assembly includes a magnet base 211 provided on one side of the spool 10 and at least one arc-shaped magnet 212 consisting of a plurality of magnets. The magnet base 211 is provided with at least one mounting post 2114 and a slide base 213. Each arc-shaped magnet 212 is mounted on one slide base 213, and the bottom of the arc-shaped magnet 212 is located within the spool 10. One end of the slide base 213 is movably connected to the mounting post 2114 via a spring 221, and moves circumferentially and radially under the action of centrifugal force or the elastic force of the spring 221 to adjust the distance between the arc-shaped magnet 212 and the inner wall of the spool 10 when the spool 10 rotates.

[0024] Specifically, in this embodiment, the number of the arc-shaped magnets 212, mounting bases 2111, slide bases 213, and springs 221 is two, and the two mounting bases 2111 are arranged around the center of the magnet base 211. A groove 2115 is formed on one side of the mounting post 2114, and one end of the spring 221 is positioned in the groove 2115, while the other end is connected to the slide base 213. Limiting posts 2133 are further provided on both ends of the slide base 213. The centrifugal adjustment assembly 22 includes a cover plate 222. The cover plate 222 is formed with rectangular limiting holes 2221, and each limiting post 2133 is positioned in and movable within each limiting hole 2221. As a result, the slide base 213 can move circumferentially and radially under the action of centrifugal force or the elastic force of the springs 221. In this embodiment, the movement trajectory of the sliding base 212 is restricted by a combination of the restricting hole 2221, which is a rectangular hole on the cover plate 222, and the restricting post 2133. The sliding base 213 also controls the strength of the magnetic induction line near the inner wall of the spool 10 close to the arc-shaped magnet 212 under the action of the centrifugal adjusting assembly 22, thereby achieving the purpose of automatically adjusting the magnitude of the braking force.

[0025] Referring to FIG. 7, FIG. 7 shows a specific embodiment of a low-profile reel 100 of the present invention. In the illustrated embodiment, the low-profile reel 100 includes a reel body 2 and the magnetic brake mechanism 1 described in the above-described first and second embodiments. The spool 10 and magnetic brake assembly 20 of the magnetic brake mechanism 1 are attachable to the reel body 2, and the side cover assembly 30 is connected to the reel body 2. Furthermore, a fishing tackle including the above-described low-profile reel 100 is also provided. The structure of this fishing tackle, excluding the low-profile reel 100, is the same as that of a typical fishing tackle in the prior art, and includes, for example, a fishing rod, a fishing line, etc. The structure is well known to those skilled in the art and will not be repeated here.
