Description

Technical Field

[0001] This utility model relates to the field of fishing reel technology, specifically to a multi-level adjustable magnetic brake structure 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 on fishing reels mostly employ fixed magnet mounting methods, and the position of the magnetic induction wheel is also fixed. This results in non-adjustable braking force or low adjustment precision, making it impossible to match to different casting intensities and environmental conditions, thus limiting usability. Therefore, it is necessary to provide a responsive magnetic braking device capable of adjusting braking force to improve the overall performance and user experience of fishing reels. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-level adjustable magnetic brake structure, which effectively improves upon the fact that the braking force of some traditional fishing reels' magnetic brake structures is not adjustable or has low adjustment precision, making it impossible to match different casting intensities and environmental conditions, resulting in poor flexibility of use.

[0005] A multi-level adjustable magnetic brake structure is disclosed for controlling the braking force of a fishing reel. The fishing reel includes a spool, a swivel, and a side cover. The multi-level adjustable magnetic brake structure comprises a first magnetic ring, a second magnetic ring, and a magnetic induction wheel. The first and second magnetic rings are coaxially arranged with a gap between them for inserting the magnetic induction wheel. The second magnetic ring is located inside the first magnetic ring. The magnetic induction wheel is sleeved on the outside of the swivel. On the side of the magnetic induction wheel away from the side cover, there are multiple connected stepped portions that control the depth of insertion of the magnetic induction wheel between the first and second magnetic rings. Each stepped portion includes a stop surface and an inclined surface. The angle between the stop surface and the inclined surface is an acute angle. Multiple sets of distances are provided from the intersection of the stop surface and the inclined surface to the side cover. A pin that mates with the stepped portion is provided on the swivel.

[0006] Preferably, an adjusting washer and a spring are provided on the side of the rotating shaft near the side cover. The spring is sleeved on the outside of the rotating shaft, with one end of the spring abutting against the adjusting washer and the other end of the spring abutting against the magnetic induction wheel.

[0007] Preferably, the stepped portion is configured as 3 groups, each of the 3 groups of stepped portions includes two stepped portions arranged opposite each other, the distance between the highest point of the 3 groups of stepped portions near the side cover and the side cover is different, and the two stepped portions arranged opposite each other are the same.

[0008] Preferably, the connection between the stop surface of the step portion and the inclined surface of the adjacent step portion is set as an arc-shaped chamfer.

[0009] Preferably, the top surface of the magnetic induction wheel is provided with a gear position indicator and a rotation direction indicator.

[0010] Preferably, the first magnetic ring component includes a plurality of floating magnet mounting seats arranged in a ring on the inner side of the side cover. The floating magnet mounting seats have mounting grooves on the side facing the second magnetic ring component, and arc-shaped magnets are disposed in the mounting grooves. Guide strips are provided on both sides of the floating magnet mounting seats, and the guide strips are connected to the side cover by an elastic element so that the floating magnet mounting seats are floatingly mounted inside the side cover.

[0011] Preferably, there are two floating magnet mounting bases, symmetrically arranged inside the side cover.

[0012] A fishing reel includes a reel body, a spool for reeling in and out fishing line and capable of rotating relative to the reel body, a shaft for driving the spool to rotate, and a side cover, and also includes the multi-level adjustable magnetic brake structure.

[0013] Furthermore, the main body of the fishing reel includes a main shaft, and the spool is sleeved on the main shaft and forms a transmission connection with the main shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model provides a multi-level adjustable magnetic brake structure, which includes a first magnetic ring, a second magnetic ring, and a magnetic induction wheel. By engaging a stepped portion on the magnetic induction wheel with a pin on the rotating shaft, the insertion depth of the magnetic induction wheel relative to the first and second magnetic rings can be adjusted, thereby effectively controlling the change in the magnetic field strength experienced by the magnetic induction wheel and achieving precise graded control of the braking force. This multi-level adjustable magnetic brake structure is simple in design and convenient to adjust, avoiding complex mechanical adjustment devices, improving reliability and adaptability, meeting the differentiated needs for braking force in different usage scenarios, and enhancing the maneuverability and applicability of the fishing reel.

Detailed Implementation

[0026] 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.

[0027] See Figures 1-8This embodiment provides a multi-level adjustable magnetic brake structure for controlling the braking force of a fishing reel. The fishing reel includes a spool 20, a rotating shaft 40, and a side cover 10. The multi-level adjustable magnetic brake structure includes a first magnetic ring 23, a second magnetic ring 24, and a magnetic induction wheel 21. The first magnetic ring 23 and the second magnetic ring 24 are coaxially arranged with a gap between them for inserting the magnetic induction wheel 21. The second magnetic ring 24 is located inside the first magnetic ring 23. The magnetic induction wheel 21 is sleeved on the outside of the rotating shaft 40. On the side of the induction wheel 21 away from the side cover 10, there are multiple connected stepped portions 80 that control the depth of the magnetic induction wheel 21 inserted between the first magnetic ring 23 and the second magnetic ring 24. Each stepped portion 80 includes a stop surface 81 and an inclined surface 82. The angle between the stop surface 81 and the inclined surface 82 is an acute angle. The distance from the intersection of the stop surface 81 and the inclined surface 82 to the side cover 10 is set in multiple different groups. A pin 70 that cooperates with the stepped portion 80 is provided on the rotating shaft 40.

[0028] It should be noted that when adjusting the gears of the multi-gear adjustable magnetic brake structure in this embodiment, it is only necessary to rotate the magnetic induction wheel 21 by hand, so that the pin 70 on the rotating shaft 40 slides along the step portion 80 on the magnetic induction wheel 21. Since the inclined surface 82 of each step portion 80 is connected to the stop surface 81 of the adjacent step portion 80, when the magnetic induction wheel 21 is rotated, the pin 70 will travel along the inclined surface 82 of this step portion 80 and reach the corner where the stop surface 81 and the inclined surface 82 of the next step portion 80 intersect. That is, during the rotation of the magnetic induction wheel 21, the pin 70 slides along the inclined surface 82 and jumps to the intersection of the stop surface 81 and the inclined surface 82 of the next step portion 80, thereby realizing the switching and stable positioning of a gear. The distance from the corner where the stop surface 81 and the inclined surface 82 of each stepped portion 80 intersect the side cover 10 increases or decreases sequentially, causing the insertion depth of the magnetic induction wheel 21 relative to the first magnetic ring 23 and the second magnetic ring 24 to change, thereby adjusting the magnetic field strength and achieving three-level control of the braking force. It should also be noted that the greater the depth to which the magnetic induction wheel 21 extends into the first magnetic ring 23 and the second magnetic ring 24, the greater the magnetic braking force, and vice versa.

[0029] Preferably, an adjustment washer 50 and a spring 60 are provided on the side of the rotating shaft 40 near the side cover 10. The spring 60 is sleeved on the outside of the rotating shaft 40, and one end of the spring 60 abuts against the adjustment washer 50, while the other end of the spring 60 abuts against the magnetic induction wheel 21. First, when the user rotates the magnetic induction wheel 21 to switch gears, the spring 60 is in a compressed state. When the newly selected step 80 aligns with the pin 70, the spring force released by the spring 60 provides a downward thrust along the length of the shaft 40 to the magnetic induction wheel 21, causing the pin 70 to be firmly locked at the corner where the stop surface 81 and the inclined surface 82 of the step 80 intersect. This completes the automatic positioning and connection of the magnetic induction wheel 21 with the selected gear, improving operational convenience and stability. Second, the spring 60 can continuously apply preload to the magnetic induction wheel 21 during operation to prevent the magnetic induction wheel 21 from loosening, deflecting, or dislodging due to vibration or inertia, thereby ensuring that the brake gear remains stable. In addition, the spring 60 can also play a role in buffering and shock absorption, absorbing some of the impact force during switching or throwing, extending the service life of structural components and improving the overall user experience.

[0030] Preferably, the stepped portion 80 is configured in three groups, each group comprising two opposing stepped portions 80. The distance between the highest point of the three groups of stepped portions 80 near the side cover 10 and the side cover 10 is different, and the opposing stepped portions 80 are identical. Through this configuration, the three groups of stepped portions 80 correspond to different depths of insertion of the magnetic induction wheel 21 into the first magnetic ring 23 and the second magnetic ring 24, thereby achieving three levels of braking force adjustment. Specifically, when the pin 70 is engaged in the first group of stepped portions 80, the magnetic induction wheel 21 is inserted to the shallowest depth, experiencing the lowest magnetic field strength, corresponding to a smaller braking force; when the pin 70 is engaged in the second group of stepped portions 80, the insertion depth is moderate, and the braking force is at a medium level; while when the pin 70 is engaged in the third group of stepped portions 80, the insertion depth is maximum, the magnetic field strength of the magnetic induction wheel 21 is highest, corresponding to the maximum braking force. During fishing, adjusting different gears allows the user to quickly switch braking gears according to the actual fishing environment and casting needs, achieving more flexible and personalized operation. In addition, the relatively symmetrical arrangement of the step portion 80 helps to maintain the balance of the magnetic induction wheel 21 during rotation, avoid structural sway, and improve the smoothness of operation and mechanical stability.

[0031] Furthermore, the stepped section 80 is arranged in a stepped, equidistant manner, with consistent height differences between adjacent groups, which helps improve the consistency of gear shifting and the tactile feedback. Through the positioning structure that cooperates with the pin 70, clear tactile feedback of the gear position can be achieved, avoiding misoperation or gear skipping issues, and improving the overall accuracy and user experience.

[0032] Preferably, the connection between the stop surface 81 of the stepped portion 80 and the inclined surface 82 of the adjacent stepped portion 80 is set with an arc-shaped guide angle 83 to guide the pin 70 to transition smoothly. Specifically, the arc-shaped guide angle 83 is set at the connection between the two stepped surfaces, which can prevent the pin 70 from getting stuck or impacted due to the sharp angle transition during gear switching, thereby improving the smoothness and responsiveness of the rotation of the magnetic induction wheel 21. In addition, the arc-shaped guide angle 83 can also disperse local stress and reduce structural wear, avoid metal fatigue or structural damage caused by frequent switching, effectively extend the service life of the magnetic induction wheel 21 and the pin 70, and improve the durability and reliability of the overall structure.

[0033] Preferably, the top surface of the magnetic induction wheel 21 is provided with a gear position indicator 90 and a rotation direction indicator. The gear position indicator 90 is used to indicate the current braking gear position of the magnetic induction wheel 21, and the user can quickly identify the current braking force level by observing the indicator, so as to select the appropriate gear according to the fishing needs; the rotation direction indicator is used to indicate the rotatable operating direction of the magnetic induction wheel 21, so as to avoid structural damage or adjustment failure caused by misoperation.

[0034] Preferably, the first magnetic ring component 23 includes a plurality of floating magnet mounting seats 11 arranged in a ring on the inner side of the side cover 10. Each floating magnet mounting seat 11 has a mounting groove 12 on the side facing the second magnetic ring component 24, and an arc-shaped magnet 13 is disposed within the mounting groove 12. Guide strips 14 are provided on both sides of the floating magnet mounting seat 11, and the guide strips 14 are connected to the side cover 10 via an elastic element to allow the floating magnet mounting seat 11 to float within the side cover 10. In this application, the elastic element is a torsion spring 15. During operation, the faster the rotation speed of the magnetic induction wheel 21, the more continuously the magnetic induction wheel 21 on the spool 20 cuts the static magnetic field of the arc-shaped magnet 13 on the floating magnet mounting seat 11, resulting in a significant increase in the rate of change of magnetic flux passing through the magnetic induction wheel 21. According to Faraday's law of electromagnetic induction, this change induces strong eddy currents within the toroidal conductor. The induced magnetic field generated by these eddy currents is opposite in direction to the magnetic field polarity of the arc-shaped magnet 13, thus pushing the floating magnet mounting base 11 to overcome the resistance of the elastic element and move towards the magnetic induction wheel 21. Consequently, the distance between the arc-shaped magnet 13 and the magnetic induction wheel 21 decreases. Since the strength of the magnetic field is inversely proportional to the square of the distance, the braking force of the arc-shaped magnet 13 on the spool 20 increases, and the elastic element is stretched and stores elastic potential energy during this process. When the rotational speed of the spool 20 decreases, the rate of change of magnetic flux through the magnetic induction wheel 21 decreases, resulting in a weakening of the induced eddy current intensity. The elastic potential energy of the elastic element is released, pulling the floating magnet mounting base 11 back to its original position. The distance between the arc-shaped magnet 13 and the magnetic induction wheel 21 increases, and the braking force decreases simultaneously. Therefore, the first magnetic ring 23 can automatically and sensitively adjust the braking force according to the change in the rotation speed of the shaft 40, adjust the balance between the line release speed of the spool and the movement speed of the bait, and prevent the fishing line from piling up on the spool, causing the spool to become "stirred rice powder".

[0035] It should be noted that in this application, the second magnetic ring 24 is a multi-level magnet arranged in a ring. Of course, the first magnetic ring 23 can also be a multi-level magnet arranged in a ring, and the magnetic poles of the second magnetic ring 24 and the first magnetic ring 23 are opposite.

[0036] See Figure 5 , Figure 6 as well as Figure 7Furthermore, an annular retaining seat 16 is provided on the inner side of the side cover 10. The annular retaining seat 16 has multiple arc-shaped mounting positions 17 for mounting the floating magnet mounting base 11. Each arc-shaped mounting position 17 of the annular retaining seat 16 has a mounting hole 18 on both sides. The mounting hole 18 has a B-shaped cross-section. The opening of the B-shaped mounting hole 18 is used to accommodate the torsion spring 15 body coil and allow it to stably store energy under tension. The waist of the B-shaped mounting hole 18 is used to accommodate one end of the torsion spring 15. The other end of the torsion spring 15 is sleeved on the guide strip 14. In this application, the annular retaining seat 16 achieves a limiting connection through multiple limiting posts 19 provided on the side cover 10. Furthermore, this application also includes an arc-shaped cover plate 110, which is screwed into the mounting hole 18 of the annular retainer 16. It should be noted that the arc-shaped cover plate 110 is also screwed into the threaded hole on the limiting post 19. The arc-shaped cover plate 110 serves to limit the annular retainer 16 and prevents the torsion spring 15 from dislodging. The screw connection between the arc-shaped cover plate 110 and the limiting post 19 facilitates quick disassembly and assembly during later maintenance. Only the screws on the arc-shaped cover plate 110 need to be removed to remove the torsion spring 15 or replace the arc-shaped magnet 13, greatly improving the convenience and reliability of assembly and maintenance.

[0037] Preferably, two floating magnet mounting bases 11 are provided, symmetrically arranged within the side cover 10. This ensures the balance and stability of the magnetic braking effect. Specifically, the two sets of floating magnet mounting bases 11 are respectively installed at symmetrical positions on the annular bracket 16, enabling them to synchronously respond to the magnetic field changes generated by the high-speed rotation of the spool 20 during operation. This causes the arc-shaped magnets 13 on the two mounting bases to approach the spool 20 in the same direction and amplitude, achieving symmetrical braking control. This effectively avoids problems such as spool 20 wobbling, delayed braking response, or unstable operation caused by uneven braking force on one side, further improving the stability of the braking system and the coaxial accuracy of the spool 20, and enhancing the overall handling feel and service life of the fishing reel.

[0038] This utility model provides a multi-level adjustable magnetic brake structure, which includes a first magnetic ring 23, a second magnetic ring 24, and a magnetic induction wheel 21. By engaging a stepped portion 80 on the magnetic induction wheel 21 with a pin 70 on the rotating shaft 40, the insertion depth of the magnetic induction wheel 21 relative to the first and second magnetic rings 23 can be adjusted, thereby effectively controlling the change in the magnetic field strength experienced by the magnetic induction wheel 21 and achieving precise graded control of the braking force. This multi-level adjustable magnetic brake structure has a simple design and convenient adjustment operation, avoiding complex mechanical adjustment devices, improving reliability and adaptability, meeting the differentiated needs for braking force in different usage scenarios, and enhancing the maneuverability and applicability of fishing reels.

[0039] This embodiment also provides a fishing reel, including a reel body 30, a spool 20 for reeling in and out fishing line and capable of rotating relative to the reel body 30, a shaft 40 for driving the spool 20 to rotate, and a side cover 10, and further including the multi-position adjustable magnetic brake structure. Further, the reel body 30 includes a main shaft, and the spool 20 is sleeved on the main shaft and forms a transmission connection with the main shaft.

[0040] The fishing reel provided in this application can adjust the corresponding braking force according to different usage scenarios to prevent the line from breaking due to excessive speed of the spool 20, thereby ensuring its handling performance and reliability in various fishing environments.

[0041] 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 claims of the present utility model shall still fall within the scope of the present utility model.
