Description

Technical Field

[0001] This utility model relates to the field of fishing tackle technology, and in particular to a magnetic external damping ring brake structure. Background Technology

[0002] Existing fishing reel braking systems mainly employ magnetic brakes, centrifugal brakes, and electronic brakes, with magnetic brakes being the most widely used in the market. Most existing magnetic brakes are disc brakes, which, while capable of controlling reel speed to some extent, have the following drawbacks: 1. Limited anti-line-breakage effect: During high-speed casting, traditional magnetic brakes may not provide sufficient damping force, causing the fishing line to break during casting, affecting the user experience. 2. Insufficient casting distance: At lower speeds, the damping of traditional magnetic brakes may be too high, affecting casting distance and accuracy, and failing to meet varying casting intensities. 3. Simple structure and inflexible adjustment: Many braking systems lack dynamic adjustment capabilities, making it difficult to adapt to different fishing reel operating scenarios.

[0003] Therefore, there is still room for improvement in the existing fishing reel braking structure. Utility Model Content

[0004] This invention provides a magnetic external damping ring brake structure for fishing reels, which improves the magnetic adjustment and damping adjustment system. It realizes functions such as increasing damping to prevent line breakage during high-speed casting and automatically disengaging the damping to maintain casting distance at low speeds, which greatly improves the performance of the fishing reel braking system and solves existing technical problems.

[0005] To achieve the above objectives, this utility model provides a magnetic damping brake structure for a fishing reel. The fishing reel includes a side cover and a reel for winding fishing line. A side cover latch is installed on the open side of the side cover, and a damping seat is embedded within the side cover latch. A damping bracket is rotatably embedded within the damping seat. Both the damping seat and the damping bracket are equipped with damping components for adjusting the casting resistance of the reel. The damping component includes a small magnetic ring fixedly installed at the center of the damping seat and a large magnetic ring fixedly embedded within the damping bracket. The small and large magnetic rings are coaxially arranged. Furthermore, an annular gap is formed between the two, and a damping ring is slidably inserted into the annular gap. The damping ring is coaxially connected to the reel via a main shaft. The main shaft is equipped with pins at both ends, wherein the end of the pin near the side cover abuts against a damping cam. A bearing is provided at the end of the main shaft away from the damping ring. A spring is installed at the center of the end of the damping ring near the side cover. The main shaft passes through the spring and is equipped with a retaining ring at the end near the side cover. A washer is provided between the retaining ring and the spring. The main shaft passes through the center of the reel, and the two are arranged coaxially.

[0006] According to the preferred embodiment of the magnetic damping brake structure of this utility model, the damping bracket is provided with a damping adjustment knob, the damping adjustment knob has a gear, the gear meshes with the gear on the outside of the damping bracket, and the damping adjustment knob is used to control the rotation of the damping bracket, thereby adjusting the magnetic force between the large magnetic ring and the small magnetic ring.

[0007] According to the preferred embodiment of the present invention, the magnetic damping brake structure is a 12-pole magnetic coil, consisting of 6 N poles and 6 S poles that are alternately distributed, which is used to form a stable magnetic field during high-speed rotation.

[0008] According to the preferred embodiment of the present invention, the lower end face of the damping ring generates magnetic damping when it rotates at high speed near the upper plane of the small magnetic ring, and the spring is used to reset the damping ring when the speed decreases.

[0009] The design concept of this application is to design a magnetic external damping ring brake structure for fishing reels. The aim is to improve the existing braking system to effectively control the rotation speed of the fishing reel during casting, thereby preventing line breakage caused by excessive rotation. At the same time, it reduces damping at lower casting speeds to avoid negatively impacting casting distance. This application uses the principle of magnetic damping, combined with an innovative structural design and adjustment mechanism, to dynamically adjust the magnetic force, thus providing stable braking control and flexible casting adaptability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please refer to Figures 1 to 5 This application presents a schematic diagram of a brake structure, specifically an external damping ring brake structure for fishing reels. This structure primarily addresses the issues of line breakage and insufficient casting distance during high-speed casting. It achieves these benefits through improvements to the magnetic adjustment and damping adjustment systems, increasing damping to prevent line breakage during high-speed casting and automatically disengaging the damping at low speeds to maintain casting distance. This significantly enhances the performance of the fishing reel's braking system.

[0023] like Figure 1 and Figure 2 As shown, the magnetic damping brake structure of this application is used for fishing reels. The fishing reel includes a side cover 1 for protecting and fixing the brake assembly and a reel 12 for winding fishing line. The side cover 1 has a side cover latch 2 for locking the side cover on its open side. A damping seat 3 is embedded in the side cover latch 2. A damping bracket 4 is rotatably embedded in the damping seat 3. Both the damping seat 3 and the damping bracket 4 are provided with damping components for adjusting the casting resistance of the reel 12. The damping components are the core part of the brake structure of this application.

[0024] The damping assembly includes a small magnetic ring 14 fixedly installed at the center of the damping seat 3 and a large magnetic ring 15 fixedly embedded in the damping bracket 4. After assembly, the small magnetic ring 14 does not rotate with the damping bracket 4, serving as a fixed magnetic source for braking. Furthermore, the large magnetic ring 15 rotates with the damping bracket 4 during adjustment to adjust the magnetic force. Figure 4As shown, the small magnetic ring 14 and the large magnetic ring 15 are coaxially arranged and form an annular gap between them. A damping ring 9 is slidably inserted in the annular gap. The damping ring 9 can generate a damping effect as the spool 12 rotates at high speed. When rotating at high speed, the damping ring 9 forms resistance through magnetic cutting action to control the speed of the spool. Through the design of the annular gap, this application can better control the concentration and distribution of magnetic force.

[0025] Regarding the relevant support connections of spindle 11, such as Figure 2 and Figure 4 As shown, the damping ring 9 is coaxially connected to the reel 12 via the main shaft 11. The main shaft 11 is fixed at the center of the reel 12 to achieve stable rotational support. The main shaft 11 has pins 10 at both ends. The end of the pin 10 near the side cover 1 abuts against the damping cam 16. The end of the main shaft 11 away from the damping ring 9 is provided with a bearing 13 to enhance the stability of the main shaft 11. A spring 8 is installed at the center of the damping ring 9 near the side cover 1, and the main shaft 11 passes through the spring 8. Please refer to [reference needed]. Figure 4 and Figure 5 When the spool 12 rotates at high speed, the damping ring 9 is subjected to axial force, which overcomes the spring force of the spring 8 and slides outward. When the rotational speed of the spool 12 decreases, the spring 8 pushes the damping ring 9 back to its initial position, restoring the initial state of the damping ring 9. In addition, the main shaft 11 is equipped with a retaining ring 6 at one end near the side cover 1. A washer 7 is provided between the retaining ring 6 and the spring 8. The main shaft 11 passes through the center of the spool 12, and the two are arranged coaxially.

[0026] like Figure 2 and Figure 3 As shown, the damping bracket 4 is equipped with a damping adjustment knob 5, which has a gear. The gear meshes with a gear on the outside of the damping bracket 4. The damping adjustment knob 5 is used to control the rotation of the damping bracket 4, thereby adjusting the magnetic force between the large magnetic ring 15 and the small magnetic ring 14. That is, by manually adjusting the damping adjustment knob 5, the rotation angle of the damping bracket 4 can be changed, thereby adjusting the magnetic force between the large magnetic ring 15 and the small magnetic ring 14 to meet the needs of different throwing intensities. To ensure the stability and consistency of the adjustment process, a limiting structure can be added between the damping seat 3 and the damping bracket 4 to control the sliding range of the damping ring 9.

[0027] Furthermore, in this embodiment, both the large magnetic coil 15 and the small magnetic coil 14 are 12-pole magnetic coils with alternating N poles and S poles, used to form a stable magnetic field during high-speed rotation. When the damping bracket 4 rotates under the action of the damping adjustment knob 5, the magnetic force between the large magnetic coil 15 and the small magnetic coil 14 changes due to the repulsion of like poles and attraction of unlike poles. The magnetic force is greatest when the large magnetic coil 15 and the small magnetic coil 14 correspond to each other with N poles and S poles, and the magnetic force is smallest when N poles correspond to N poles and S poles correspond to S poles.

[0028] like Figure 4 and Figure 5 As shown, the lower end face of the damping ring 9 generates magnetic damping when it rotates at high speed, which is close to the upper plane of the small magnetic ring 14. This increases damping to prevent the line from breaking when the casting speed is too fast. The spring 8 is used to reset the damping ring 9 when the speed decreases, reducing the influence of damping on the casting distance. In other words, during the casting process, when the reel 12 rotates at high speed, the lower end face of the damping ring 9 approaches the upper plane of the small magnetic ring 14, generating magnetic damping through the cutting action of the magnetic lines of force, thus controlling the rotation speed of the reel 12. Especially when the casting force is too strong, this magnetic damping can effectively prevent the line from breaking.

[0029] In summary, the axial sliding and return of the damping ring are explained as follows: The damping ring 9 is fixed to the damping cam 16 and can slide axially on the main shaft 11. When the reel 12 reaches high-speed rotation, the damping ring 9, under the influence of centrifugal force and axial force, overcomes the supporting force of the spring 8 and slides outward, bringing it closer to the upper plane of the small magnetic ring 14, thus enhancing the magnetic damping effect. When the speed of the reel 12 decreases or stops, the damping ring 9 automatically returns to its initial position under the action of the spring 8, thereby reducing magnetic damping and ensuring that the casting distance is not affected.

[0030] The following explains the damping adjustment and adaptive functions: The damping adjustment knob 5 allows for adjustment of the magnetic force according to actual needs, thereby precisely controlling the casting resistance of the reel 12. This design can adapt to various casting intensities, whether requiring a powerful long throw or a precise, low-force throw; the automatic floating mechanism of the damping ring 9 has adaptive characteristics during casting, increasing damping when the throw is too forceful and decreasing damping when the throw force is insufficient, maximizing the smoothness and safety of the throw; the braking structure of this application, through optimizing the magnetic braking system, achieves a balance between preventing line breakage and controlling casting distance. It automatically increases damping during high-speed casting and decreases damping at low speeds, achieving a dual improvement in reliability and practicality.

[0031] It should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0032] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0033] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0034] Compared with the prior art, the present invention has the following advantages:

[0035] First, this application achieves increased damping during high-speed casting through dynamic magnetic force adjustment, thus preventing line breakage.

[0036] Second, this application reduces damping during low-speed casting to ensure that the casting distance is not affected;

[0037] Third, this application features adaptive adjustment, employing a damping adjustment knob and spring structure to dynamically adjust the damping force according to the actual operating scenario, adapting to different throwing needs.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
