Description

Technical Field

[0001] This invention relates to the field of fishing tackle technology, specifically to a segmented adaptive magnetic braking mechanism for fishing reels. Background Technology

[0002] Magnetic braking systems are a widely used spool speed control technology in modern fishing reels. The basic principle is that as the spool (usually made of conductive materials such as aluminum alloy) rotates, it cuts the stationary magnetic field generated by a fixed magnet, thus inducing eddy currents inside the spool. These eddy currents then generate a braking force (i.e., braking force) that interacts with the original magnetic field and opposes the spool's rotation. The magnitude of the braking force depends primarily on the distance between the magnet and the spool, as well as the effective area of ​​the spool cutting the magnetic field lines.

[0003] Currently, most mainstream magnetic braking mechanisms are "preset" type. Anglers need to manually drive the entire magnetic assembly axially using an external adjustment knob before casting to adjust the depth of its insertion into the reel, thereby changing the area of ​​the reel cutting the magnetic lines and thus preset a fixed braking force level.

[0004] Traditional magnetic braking mechanisms cannot respond to the dynamic changes in spool speed during casting. At the initial stage of casting, the spool speed reaches its peak instantaneously, requiring maximum braking force to prevent line breakage. Subsequently, as the lure's flight speed decreases due to air resistance, the spool speed also decreases, and the required braking force should be reduced accordingly to achieve greater distance. A fixed preset braking force cannot meet this dynamic requirement: too much preset force severely sacrifices casting distance; too little preset force results in extreme instability in the initial casting stage, making line breakage highly likely. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a segmented adaptive magnetic braking mechanism for fishing reels that can automatically adjust the braking force according to the real-time rotation speed of the spool.

[0006] The technical solution adopted in this invention is as follows: a segmented adaptive magnetic braking mechanism for fishing reels, including a reel seat, a magnet assembly built into the reel seat, and an adjustment mechanism connected to the magnet assembly. The adjustment mechanism drives the magnet assembly to move up and down to adjust its depth into the reel, thereby changing the area of ​​the reel cutting magnetic lines and realizing the adjustment of the braking force of the reel. The magnet assembly includes a mounting base, a sliding block, a magnet array, and an elastic component.

[0007] The mounting base is connected to the adjustment mechanism and is cylindrical in shape. Multiple fan-shaped cavities are provided on the outer peripheral wall of the mounting base along the circumferential direction. At least two guide grooves are provided on the axial opposite sidewalls of each fan-shaped cavity.

[0008] The sliding block is movably disposed in the fan-shaped cavity. It includes a sliding block body. The upper and lower end faces of the sliding block body are respectively provided with guide pins embedded in corresponding guide grooves. The extension trajectory of the guide groove is such that when the sliding block moves along the guide groove, the sliding block rotates around the axis of the mounting base and generates a radial outward displacement.

[0009] The magnet array is fixedly embedded on the radial outer surface of the sliding block body;

[0010] The elastic component is disposed between the sliding block and the mounting base, and is used to generate an elastic restoring force opposite to the direction of rotation when the sliding block moves;

[0011] The elastic component includes a movable intermediate block, a first spring, and a second spring. The first spring and the second spring are located on both sides of the movable intermediate block. One end of the first spring abuts against a first flange on the inner side wall of the sliding block body, and the other end abuts against one side of the movable intermediate block. One end of the second spring abuts against the other side of the movable intermediate block, and the other end abuts against a second flange provided on the mounting base.

[0012] The mounting base or movable intermediate block is provided with a limiting structure, which is configured to limit the movement of the movable intermediate block relative to the mounting base and make the movement less than the complete rotational travel of the sliding block from the initial position to the maximum braking position.

[0013] The spring constant of the first spring is greater than that of the second spring.

[0014] Furthermore, the mounting base includes a base and a cover plate, the cover plate being fastened to the bottom surface of the base by bolts, the fan-shaped cavity being formed on the outer peripheral wall of the base, and the guide groove being formed on the base and the cover plate respectively.

[0015] Furthermore, the movable intermediate block is disposed between the inner wall of the sliding block body and the base. The movable intermediate block is generally inverted T-shaped, including a base and a neck vertically connected to the base. The first spring and the second spring respectively abut against the two sides of the base. The limiting structure is a limiting groove disposed on the inner wall of the fan-shaped cavity to limit the movement stroke of the movable intermediate block. The neck of the movable intermediate block is accommodated in the limiting groove. The width of the limiting groove is such that the movement stroke of the movable intermediate block is less than the complete rotation stroke of the sliding block from the initial position to the maximum braking position.

[0016] Furthermore, the movable intermediate blocks are correspondingly disposed at the ends of each sliding block body facing its rotation direction, and each movable intermediate block is fixedly connected to a sleeve. The sleeve is coaxially sleeved on the inner ring of the base and can rotate relative to it. The limiting structure is a limiting part disposed on the base to limit the rotation stroke of the movable intermediate blocks, so that the rotation stroke of the movable intermediate blocks is less than the complete rotation stroke of the sliding block from the initial position to the maximum braking position.

[0017] Furthermore, the movable intermediate block is provided with receiving grooves for accommodating the first spring and the second spring, respectively.

[0018] Furthermore, the sliding block body has a fan-shaped structure, its axis coincides with the axis of the mounting base, and the radius of curvature of its outer peripheral wall is the same as the radius of curvature of the outer peripheral wall of the mounting base.

[0019] Furthermore, the adjustment mechanism includes an adjustment knob and a threaded post connected to the adjustment knob; the center of the mounting base is provided with an axially penetrating central hole, the inner wall of the central hole is provided with an internal thread that matches the external thread on the threaded post, the threaded post passes through the spool seat and is threadedly connected to the central hole on the mounting base; a guide engagement mechanism is provided between the mounting base and the spool seat to restrict the rotation of the mounting base relative to the spool seat.

[0020] Furthermore, the threaded post has a hollow structure; the center of the reel seat has a through hole that matches the threaded post, and a positioning post is coaxially arranged inside the through hole. The outer diameter of the positioning post matches the hollow inner diameter of the threaded post, and the threaded post is sleeved on the positioning post; the bottom of the positioning post is connected to the reel seat through at least two spaced connecting plates; the side wall of the central hole of the mounting base has a groove that matches the connecting plate; the vertical section of the connecting plate is located in the groove, and the connecting plate and the groove cooperate to form a guide bonding mechanism that restricts the rotation of the mounting base.

[0021] The beneficial effects of this invention are as follows:

[0022] (1) This invention utilizes the electromagnetic attraction force generated by electromagnetic induction itself, whose magnitude is proportional to the rotation speed of the spool, as the driving force. Through the guide groove mechanism, this radial attraction force is converted into the composite motion of the sliding block, thereby automatically adjusting the distance between the magnet and the spool, forming a negative feedback closed loop: rotation speed increases → attraction force increases → magnet moves closer → braking force increases (suppresses rotation speed); rotation speed decreases → attraction force decreases → magnet resets → braking force weakens. This changes the traditional mode where the brake needs to be manually set in advance and remains unchanged throughout the casting process, and achieves full-process self-adaptation without human intervention.

[0023] (2) A tiny radial displacement between the magnet and the spool can cause a drastic change in braking force. This invention decomposes the movement of the sliding block into a composite motion of rotation around the axis and radial displacement. On the one hand, this makes the final radial displacement smaller and easier to control precisely through the mechanical structure, thereby suppressing the drastic change in braking force caused by tiny displacement and making the output change of braking force smoother. On the other hand, the introduction of the rotation component provides a longer stroke for the elastic component to do work, making the whole braking process smoother and more controllable.

[0024] (3) This invention utilizes a two-stage variable stiffness system composed of two springs and an intermediate block. In the initial stage of casting, the magnet array can quickly and sensitively approach the spool radially to provide a larger initial braking force. As the rotation speed increases further, the spring with a larger stiffness coefficient is switched to provide resistance, making the increase of braking force more gradual. As the spool rotation speed decreases, the electromagnetic attraction weakens, and the elastic potential energy stored in the elastic component becomes dominant. It pushes the sliding block to move in the opposite direction along the guide groove, causing the magnet array to move radially away from the spool. The braking force then automatically decreases, thereby avoiding unnecessary resistance, ensuring the casting distance, and achieving the purpose of real-time, automatic, and intelligent adjustment of braking force according to the spool rotation speed.

[0025] (4) By designing hollow threaded columns, positioning columns and connecting plates, the transmission function and anti-rotation function of the adjustment mechanism are integrated on the same axis, saving space and simplifying the overall structure. Attached Figure Description

Detailed Implementation

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figure 1 As shown, this embodiment provides a segmented adaptive magnetic braking mechanism for fishing reels, including a reel seat 2, a magnet assembly 3 built into the reel seat 2, and an adjustment mechanism 1 connected to the magnet assembly 3. The adjustment mechanism 1 drives the magnet assembly 3 to move up and down to adjust its depth into the reel, thereby changing the area of ​​the reel cutting the magnetic field lines and realizing the adjustment of the braking force of the reel.

[0039] like Figure 1 , Figure 2 As shown, in this embodiment, the magnet assembly 3 includes a mounting base 310 and a sliding block 320, a magnet array 330, and an elastic component 340 mounted on the mounting base 310. The mounting base 310 is cylindrical in shape and is connected to the adjustment mechanism 1. The adjustment mechanism 1 drives the mounting base 310 to move up and down, thereby preset a fixed braking force level.

[0040] like Figure 1 , Figure 2 , Figure 6 , Figure 7As shown, in this embodiment, the adjustment mechanism 1 includes an adjustment knob 101 and a threaded post 102 connected to the adjustment knob 101. The threaded post 102 has a hollow structure and external threads on its outer circumferential surface. The center of the reel seat 2 has a through hole 201 that matches the threaded post 102. A positioning post 202 is coaxially arranged inside the through hole 201. The outer diameter of the positioning post 202 matches the hollow inner diameter of the threaded post 102. The threaded post 102 is sleeved on the positioning post 202. The bottom of the positioning post 202 is connected to the reel seat 2 as a whole through two spaced connecting plates 203. The center of the mounting base 310 has an axially penetrating central hole 317. The threaded post 102 and the positioning post 202 are both located in the central hole 317. The inner wall of the central hole 317, corresponding to the gap between it and the connecting plate 203, has internal threads that match the external threads on the threaded post 102. The side wall of the central hole 317 is provided with a groove 318 that matches the connecting plate 203. The vertical section of the connecting plate 203 is located in the groove 318. The connecting plate 203 and the groove 318 cooperate to form a guide keying mechanism that restricts the rotation of the mounting base 310. The threaded post 102 is inserted into the through hole 201 and engages with the thread on the inner wall of the central hole 317. By adjusting the knob 101, the threaded post 102 is driven to rotate. The mounting base 310 cannot rotate due to the restriction of the connecting plate 203, thus achieving vertical displacement.

[0041] like Figures 2-4 As shown, in this embodiment, two symmetrically arranged fan-shaped cavities are provided on the outer peripheral wall of the mounting base 310 along the circumferential direction, and two sliding blocks 320 are respectively movably disposed in the two fan-shaped cavities. Two guide grooves 314 are provided on the axially opposite sidewalls of each fan-shaped cavity. The sliding block 320 includes a sliding block body 321, and guide pins 322 embedded in the corresponding guide grooves 314 are respectively provided on the upper and lower end faces of the sliding block body 321. The extension trajectory of the guide grooves 314 is such that when the sliding block 320 moves along the guide grooves 314, the sliding block 320 rotates around the axis of the mounting base 310 while simultaneously generating a radially outward displacement (see...). Figure 5 The magnet array 330 is fixedly embedded on the radial outer surface of the sliding block body 321. For ease of assembly, in this embodiment, the mounting base 310 includes a base 311 and a cover plate 312. The cover plate 312 is fastened to the bottom surface of the base 311 by bolts 313. A fan-shaped cavity is formed on the outer peripheral wall of the base 311, and guide grooves 314 are respectively formed on the base 311 and the cover plate 312.

[0042] In this embodiment, the sliding block body 321 has a fan-shaped structure, its axis coincides with the axis of the mounting base 310, and the radius of curvature of its outer peripheral wall is the same as the radius of curvature of the outer peripheral wall of the mounting base 310, thereby maintaining a uniform gap with the inner wall of the spool and generating a stable and uniform braking force.

[0043] The elastic component 340 is disposed between the sliding block 320 and the inner wall of the fan-shaped cavity of the mounting base 310, so that when the sliding block 320 moves, it generates a force opposite to its rotation direction. In this embodiment, the elastic component 340 includes a movable intermediate block 341, a first spring 342, and a second spring 343. The first spring 342 and the second spring 343 are respectively located on both sides of the movable intermediate block 341. One end of the first spring 342 abuts against the first flange 323 on the inner sidewall of the sliding block body 321, and the other end abuts against one side of the movable intermediate block 341. One end of the second spring 343 abuts against the other side of the movable intermediate block 341, and the other end abuts against the second flange 316 provided on the inner wall of the fan-shaped cavity. A limiting groove 315 is also provided on the inner wall of the fan-shaped cavity to limit the movement stroke of the movable intermediate block 341. The width of the limiting groove 315 is less than the complete rotation stroke of the sliding block 320 from the initial position to the maximum braking position. During operation, the high-speed rotating reel cuts the magnetic field lines, generating a force on the magnet array 330 tending towards the central axis of the reel. Under the combined action of this driving force and the guide groove 314, the sliding block 320 undergoes a combined motion of rotation around the axis of the mounting base 310 and radial displacement. Initially, the sliding block body 321 pushes the movable intermediate block 341 to compress the second spring 343 via the first spring 342. When the movable intermediate block 341 moves into position and is blocked by the wall of the limiting groove 315, the sliding block body 321 continues to rotate, compressing only the first spring 342, while the compression of the second spring 343 remains unchanged. In this embodiment, the stiffness coefficient of the first spring 342 is greater than that of the second spring 343. This design creates a sensitive starting phase, providing a non-linear response that is "extremely soft initially, then extremely hard," effectively preventing unnecessary excessive increase in braking force in the later stages. This not only prevents line breakage but also contributes to a superior casting distance.

[0044] In this embodiment, the movable intermediate block 341 is generally inverted T-shaped, including a base and a neck vertically connected to the base. The neck is accommodated in the limiting groove 315, and the first spring 342 and the second spring 343 respectively abut against the two sides of the base.

[0045] Example 2

[0046] like Figure 8 , Figure 9As shown in the figure, the difference between this embodiment and Embodiment 1 lies in the specific structure of the movable intermediate block 341. In this embodiment, the movable intermediate block 341 is correspondingly arranged at the end of each sliding block body 321 facing its rotation direction, and each movable intermediate block 341 is fixedly connected to a sleeve 344 together. The sleeve 344 is coaxially sleeved on the inner ring of the base 311 and can rotate relative to it. A limiting portion for restricting the rotation stroke of the movable intermediate block 341 is provided on the base 311, so that the rotation stroke of the movable intermediate block 341 is less than the complete rotation stroke of the sliding block 320 from the initial position to the maximum braking position.

[0047] During operation, the sliding block 320 undergoes a combined movement of rotation around the axis of the mounting seat 310 and radial displacement along the guiding groove 314 under the action of the driving force generated by the wire wheel cutting the magnetic induction line. In the initial stage, the sliding block body 321 pushes the movable intermediate block 341 and the sleeve 344 to rotate through the first spring 342, and at the same time compresses the second spring 343. When the movable intermediate block 341 moves in place and is blocked by the limiting portion on the base 311, the positions of the movable intermediate block 341 and the sleeve 344 are limited. When the sliding block body 321 continues to rotate, only the first spring 342 can be compressed, and the compression amount of the second spring 343 remains unchanged. Through this design, the non-linear response of "first extremely soft, then extremely hard" is also achieved, and the number of parts is reduced, and the assembly process is simplified. The force is transmitted through the sleeve 344 to achieve linkage, which can trigger the coordinated response of all magnet arrays 330.

[0048] In this embodiment, receiving grooves for respectively accommodating the first spring 342 and the second spring 343 are provided on the movable intermediate block 341 to achieve precise installation and positioning of the first and second springs.

[0049] See Figure 8 In addition, the difference between this embodiment and Embodiment 1 also lies in the structure of the guiding keying mechanism between the mounting seat 310 and the wire wheel seat 2. In this embodiment, a convex block is provided upward on the upper end surface of the base 311. By providing a notch on the wire wheel seat 2 that matches the convex block, the convex block is embedded in the notch. When the rotation adjustment knob 101 and the threaded column 102 are rotated, the mounting seat 310 cannot rotate, and thus the up and down displacement is achieved.

[0050] The above content is only an example and illustration of the structure of the present invention. Those skilled in the art of this technology can make various modifications or supplements to the described specific embodiments or use similar methods for substitution. As long as they do not deviate from the structure of the present invention or exceed the scope defined by this claim book, they should fall within the protection scope of the present invention.
