Description
Technical Field
[0001] This utility model relates to the field of fishing reel technology, specifically to a floating magnetic brake structure inside a reel and a fishing reel. Background Technology
[0002] A fishing reel is a common casting device used in fishing activities. Its main function is to provide sensitive and controllable spool rotation during casting. Currently, the braking systems widely used in mid-to-high-end fishing reels are mainly of two types: mechanical brakes and magnetic brakes. Among them, magnetic brakes, due to their advantages of being contactless and having low wear, perform particularly well in high-speed casting and high-precision control, and are gradually becoming the mainstream development direction for fishing reel braking systems.
[0003] Existing magnetic braking structures mostly employ a fixed magnet mounting method, where the magnet is fixedly installed on the side cover of the fishing reel, relying on the electromagnetic eddy currents generated when it rotates relative to the reel to achieve braking. While this structure can achieve a certain braking effect, the fixed magnet cannot automatically adjust the distance between itself and the reel according to the reel's rotation speed. This makes it difficult to maintain braking force at both high and low speeds, resulting in insensitive braking response and risks of over-winding or line breakage on the reel. Furthermore, the fixed structure cannot effectively buffer the vibrations and impacts from high-speed rotation, affecting the stability and lifespan of the braking system.
[0004] In view of this, some technical solutions have attempted to introduce adjustable magnetic braking structures, but problems such as response lag and limited adjustment range still exist. Therefore, it is necessary to provide a floating magnetic braking structure within the fishing reel that is responsive and can automatically adjust the braking force according to the reel speed to improve the overall performance and operating experience of the fishing reel. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a floating magnetic brake structure within the reel and a fishing reel, effectively improving some of the problems of slow response, insensitive adjustment, and poor vibration resistance in traditional magnetic brake structures.
[0006] A floating magnetic brake structure is disclosed inside a fishing reel. Installed within the side cover of the reel, it acts on the reel. The structure includes a magnet bracket arranged in a ring shape in the middle of the inner side of the side cover, and at least two floating magnet mounting seats levitably connected to the magnet bracket. The floating magnet mounting seats are fitted inside the reel. Multiple magnetic beads are arranged on the side of the floating magnet mounting seat facing the inner wall of the reel, with adjacent magnetic beads having opposite magnetic poles. The reel cuts the magnetic lines of force generated by the magnetic beads, thereby achieving magnetic braking.
[0007] Preferably, there are two floating magnet mounting bases, which are arranged symmetrically.
[0008] Preferably, the outer side of both ends of the floating magnet mounting base has a recessed receiving groove on the inner side, and a plug-in post is provided at the receiving groove. An elastic element is sleeved on the plug-in post, and the side of the elastic element away from the floating magnet mounting base abuts against the magnet bracket, thereby realizing the floating connection between the floating magnet mounting base and the magnet bracket.
[0009] Preferably, the elastic element includes two helical springs and a connecting strip between the two helical springs. The two helical springs are respectively sleeved on the ends of the two floating magnet mounting bases on adjacent sides, and the connecting strip abuts against the side wall of the magnet bracket.
[0010] Preferably, it further includes a mounting base, which is disposed on the side cover. The magnet bracket is mounted on the side of the mounting base near the reel, and a magnet base is disposed on the side of the mounting base away from the reel. Both the magnet bracket and the magnet base are provided with connecting posts on their sides. The magnet bracket and the magnet base are connected by a bolt inserted into the connecting post.
[0011] Preferably, the mounting base is provided with a through hole at the connecting post of the magnet base to allow the connecting post to move.
[0012] Preferably, the mounting base has a first cam step on the side away from the spool, and the knob located at the top center of the side cover has a second cam step on the side near the spool. The first cam step and the second cam step rotate in cooperation to adjust the stroke of the spool extending between the magnetic beads.
[0013] Furthermore, a return spring is provided between the mounting base and the magnet base.
[0014] Preferably, the side of the magnet bracket is provided with a through groove for placing the floating magnet mounting base.
[0015] A fishing reel includes a main body, a reel for reeling in and out fishing line and capable of rotating relative to the main body, and a side cover, wherein a floating magnetic brake structure for the reel is installed inside the side cover.
[0016] Preferably, the fishing reel body includes a main shaft, and the reel is sleeved on the main shaft and forms a transmission connection with the main shaft.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This invention provides a floating magnetic braking structure within a spool, comprising a magnet bracket and at least two floating magnet mounting seats buoyantly connected to the magnet bracket. Multiple magnetic beads are arranged on the side of the floating magnet mounting seats facing the inner wall of the spool. During operation, as the spool rotates faster, it continuously and rapidly cuts the static magnetic field between the magnetic beads on the floating magnet mounting seats, resulting in a significant increase in the rate of change of magnetic flux through the spool. According to Faraday's law of electromagnetic induction, this change induces strong eddy currents within the spool, which in turn push the floating magnet mounting seats towards one side of the spool, thus reducing the distance between the magnetic beads and the annular conductor. Since the strength of the magnetic field is inversely proportional to the square of the distance, the braking force of the magnetic beads on the spool increases. When the spool rotation speed decreases, the rate of change of magnetic flux through the magnetic beads decreases, leading to a weakening of the induced eddy current intensity. The floating magnet mounting seats slowly return to their original position, the distance between the magnetic beads and the spool increases, and the braking force decreases accordingly. Therefore, this floating magnetic brake structure can automatically and sensitively adjust the braking force according to the change of spool speed during casting, balancing the line release speed and bait movement speed, preventing line from piling up on the spool and causing it to become "stirred up," and avoiding the problem of traditional fixed magnet structures not being able to automatically adjust the braking force at different speeds, thus improving overall stability and controllability. This application also provides a fishing reel that includes the aforementioned floating magnetic brake structure within the spool. By integrating this brake structure inside the side cover of the fishing reel, the reel can adaptively adjust the spool rotation speed during use, eliminating the need for manual adjustment of the braking force by the user, significantly improving the ease and stability of casting. This fishing reel can achieve rapid and effective braking during high-speed casting, preventing the spool from spinning too fast and causing line breakage or tangling; at low speeds, it can automatically reduce the braking force to ensure smooth casting and avoid dragging or jamming. Therefore, it is suitable for various types of fishing scenarios. Attached Figure Description

Detailed Implementation
[0028] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0029] See Figures 1-7 This embodiment provides a floating magnetic brake structure inside a fishing reel. It is installed inside the side cover 10 of the fishing reel and acts on the reel 20. It includes a magnet bracket 30 arranged in a ring in the middle of the inner side of the side cover 10 and at least two floating magnet mounting seats 40 floatingly connected to the magnet bracket 30. The floating magnet mounting seats 40 are sleeved inside the reel 20. Multiple magnetic beads 50 are arranged on the side of the floating magnet mounting seat 40 facing the inner side wall of the reel 20. The magnetic poles of adjacent magnetic beads 50 are opposite. The reel 20 cuts the magnetic lines of force generated by the magnetic beads 50 to achieve magnetic braking.
[0030] Preferably, there are two floating magnet mounting bases 40, which are symmetrically arranged. In this application, the two floating magnet mounting bases 40 are arranged in a semi-circular shape. Multiple mounting slots 60 are provided on the outer side of each floating magnet mounting base 40. Each mounting slot 60 has a magnetic bead 50. If the magnetic bead 50 installed in a particular mounting slot 60 is of the N-pole, then the magnetic bead 50 in the two adjacent mounting slots 60 are of the S-pole. Conversely, if the magnetic bead 50 installed in a particular mounting slot 60 is of the S-pole, then the magnetic bead 50 in the two adjacent mounting slots 60 are of the N-pole. Of course, the magnetic bead 50 installed in the end mounting slot 60 has only one magnetic bead 50 on its periphery with the opposite magnetic pole. In this application, in order to distinguish the magnetic poles of the magnetic bead 50, the magnetic bead 50 with different magnetic poles is set to different colors, such as red for N pole and blue for S pole, and the N pole and S pole are set to different sizes to achieve a foolproof design.
[0031] Preferably, the outer side of each end of the floating magnet mounting base 40 facing inward has a recessed receiving groove 41. A plug-in post 42 is provided at the receiving groove 41, and an elastic element 43 is sleeved on the plug-in post 42. The side of the elastic element 43 away from the floating magnet mounting base 40 abuts against the magnet bracket 30, thereby realizing the floating connection between the floating magnet mounting base 40 and the magnet bracket 30. The elastic element 43 includes two helical springs and a connecting strip connecting the two helical springs. The two helical springs are respectively sleeved on the ends of the two floating magnet mounting bases 40 on adjacent sides, and the connecting strip abuts against the side wall of the magnet bracket 30.
[0032] It should be noted that during use, when the reel 20 is rotating at high speed, the magnetic lines of force are rapidly cut, increasing the induced eddy currents. Under the influence of magnetic force, the floating magnet mounting base 40 moves closer to the reel 20, compressing the helical spring and reducing the gap between the magnetic bead 50 and the reel 20, thus enhancing the braking force. As the rotational speed decreases, the induced eddy currents diminish, and the helical spring becomes more elastic, causing the floating magnet mounting base 40 to slowly return to its original position, moving it away from the reel 20 and reducing the braking force. Therefore, automatic adjustment of the braking force throughout the entire process can be achieved without user intervention. Compared to a rigid connection, the floating connection via the elastic element 43 effectively responds to changes in the rotational speed of the reel 20, automatically adjusting the braking force and improving overall sensitivity and comfort.
[0033] Preferably, the device further includes a mounting base 70, which is disposed on the side cover 10. The magnet bracket 30 is mounted on the side of the mounting base 70 closest to the reel 20, and a magnet base 80 is disposed on the side of the mounting base 70 furthest from the reel 20. Both the magnet bracket 30 and the magnet base 80 have connecting posts 90 on their sides. The magnet bracket 30 and the magnet base 80 are connected by a bolt inserted into the connecting post 90. The mounting base 70 has a through hole 11 corresponding to the connecting post 90 of the magnet base 80 for the connecting post 90 to move through.
[0034] Preferably, the mounting base 70 is provided with a first cam step 12 on the side away from the spool 20, and the knob 18 located at the top center of the side cover 10 is provided with a second cam step 13 on the side near the spool 20. The first cam step 12 and the second cam step 13 rotate in cooperation to adjust the stroke of the spool 20 extending into the magnetic bead 50. In this application, two of each of the first cam step 12 and the second cam step 13 are provided and arranged symmetrically. During adjustment, by turning the knob, the second cam step 13 rotates relative to the first cam step 12. Since both the second cam step 13 and the first cam step 12 are cam steps with increasing height, when the second cam step 13 is rotated to its highest point and abuts against the highest point of the first cam step 12, the magnet bracket 30 is at its lowest point. At this time, the area between the magnetic bead 50 and the reel 20 is the largest, resulting in a greater braking force. When the second cam step 13 is rotated to its lowest point and abuts against the lowest point of the first cam step 12, the magnet bracket 30 is at its highest point. At this time, the area between the magnetic bead 50 and the reel 20 is the smallest, resulting in a smaller braking force.
[0035] In actual use, users can adjust the brake stroke in advance by rotating the knob according to factors such as target fish species, casting distance, water flow intensity, and wind force. If a stronger braking effect is needed, the knob can be turned clockwise so that the high point of the second cam step 13 contacts the high point of the first cam step 12, thereby lowering the magnet bracket 30 and bringing the magnetic bead 50 closer to the reel 20, increasing the magnetic resistance and achieving strong braking. If a weaker braking force is needed, the knob can be turned counterclockwise so that the low point of the second cam step 13 contacts the low point of the first cam step 12, raising the magnet bracket 30 and moving the magnetic bead 50 away from the reel 20, reducing the magnetic induction and achieving a light braking effect.
[0036] Furthermore, a return spring 14 is provided between the mounting base 70 and the magnet base 80, and the return spring 14 is connected to both the mounting base 70 and the magnet base 80. The return spring 14 is preferably a helical compression spring, disposed within the axial channel between the mounting base 70 and the magnet base 80. In its natural state, it is in a compressed state, used to automatically apply a return thrust to the magnet bracket 30 after adjustment by the knob. When the user adjusts the position of the second cam step 13 by the knob, causing the magnet bracket 30 to shift, the return spring 14 is compressed or released, thereby storing or releasing elastic energy, and thus selectively applying a return thrust to the magnet bracket 30.
[0037] Preferably, the magnet bracket 30 has a through groove 15 on its side for placing the floating magnet mounting base 40. A baffle 16 is provided at the bottom of the magnet bracket 30, and the floating magnet mounting base 40 is installed in the through groove 15. The baffle 16 is located at the bottom of the magnet bracket 30, thereby allowing the magnet bracket 30 and the baffle 16 to cooperate in limiting the axial movement of the floating magnet mounting base 40.
[0038] This invention provides a floating magnetic braking structure within a spool, comprising a magnet support 30 and at least two floating magnet mounting seats 40 floatingly connected to the magnet support 30. Multiple magnetic beads 50 are disposed on the side of the floating magnet mounting seat 40 facing the inner wall of the spool 20. During operation, the faster the spool 20 rotates, the more rapidly it cuts the static magnetic field between the magnetic beads 50 on the floating magnet mounting seat 40, resulting in a significant increase in the rate of change of magnetic flux through the spool 20. According to Faraday's law of electromagnetic induction, this change induces strong eddy currents within the spool 20, thereby pushing the floating magnet mounting seat 40 towards one side of the spool 20, thus reducing the distance between the magnetic beads 50 and the annular conductor. Since the strength of the magnetic field is inversely proportional to the square of the distance, the braking force of the magnetic beads 50 on the spool 20 increases. As the rotational speed of the reel 20 decreases, the rate of change of magnetic flux through the magnetic bead 50 decreases, leading to a weakening of the induced eddy current intensity. The floating magnet mounting base 40 slowly returns to its original position, increasing the distance between the magnetic bead 50 and the reel 20, and the braking force decreases accordingly. Therefore, this floating magnetic braking structure can automatically and sensitively adjust the braking force according to the speed changes of the reel 20 during casting, balancing the line release speed of the reel 20 with the lure's movement speed. This prevents the fishing line from piling up on the reel 20, avoiding the "rice flour" effect, and also avoids the problem of traditional fixed magnet structures failing to automatically adjust braking force at different speeds, thus improving overall stability and controllability.
[0039] This embodiment also provides a fishing reel, including a fishing reel body 21, a reel 20 for reeling in and out fishing line and capable of rotating relative to the fishing reel body 21, and a side cover 10, wherein the side cover 10 is provided with the floating magnetic brake structure inside the reel.
[0040] Preferably, the fishing reel body 21 includes a main shaft 22, and the reel 20 is sleeved on the main shaft 22 and forms a transmission connection with the main shaft 22. More preferably, the reel 20 is made of a high magnetic permeability material, such as magnetic stainless steel or nickel-iron alloy, so as to efficiently respond to the magnetic flux changes generated by the magnetic bead 50.
[0041] This application also provides a fishing reel including the aforementioned floating magnetic brake structure within the reel. By integrating this brake structure inside the side cover 10 of the fishing reel, the reel can adaptively adjust the rotation speed of the reel 20 during use, eliminating the need for manual adjustment of the braking force by the user, significantly improving the ease and stability of casting. This fishing reel can achieve rapid and effective braking during high-speed casting, preventing the reel 20 from rotating too quickly and causing line breakage or tangling; at low speeds, it automatically reduces the braking force to ensure smooth casting and avoid dragging or jamming. Therefore, it is suitable for various types of fishing scenarios.
[0042] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
