Description

Technical Field

[0001] This utility model relates to the field of fishing gear technology, and more specifically, to a brake assembly mechanism for a teardrop fishing reel. Background Technology

[0002] Baitnet reels are commonly used in lure fishing, functioning to wind the fishing line, control line release speed, and assist in casting and reeling. To achieve precise casting control, modern baitnet reels often employ electronic braking systems. These systems typically include an electromagnet linked to the spool, a PCB control board, and an adjustment knob for adjusting the braking force. However, current braking mechanisms often have the PCB control board and adjustment knob loosely mounted within the reel's side cover, resulting in a loose overall structure, cumbersome assembly, and difficulty in maintenance. More importantly, the adjustment knob often lacks an effective waterproof seal between itself and the housing. In near-water environments like fishing, moisture, rain, dust, and other impurities can easily seep into the reel through the knob's openings, causing the electronic components on the PCB control board (especially the potentiometers used for adjustment) to become damp, short-circuit, or corrode. This severely affects the accuracy and reliability of the braking adjustment, and may even lead to complete braking system failure. In addition, the rotation mechanism of its adjustment knob often suffers from play and eccentricity due to the lack of precise radial limit, which affects the operating feel and adjustment accuracy. Utility Model Content

[0003] The present invention provides a brake assembly mechanism for a teardrop fishing reel, which can solve the above-mentioned problems.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A brake assembly mechanism for a baitcasting reel includes a cup-lid encapsulation shell, a spool cover, an adjustment knob, a knob seat, a double sealing structure, a radial limiting structure, and a brake module mounted on the spool cover and housing a PCB control board. The brake module includes a module seat and a module cover. The double sealing structure includes a first sealing ring disposed between the adjustment knob and the knob seat, and a second sealing ring disposed between the knob seat and the module cover. The radial limiting structure includes an integral annular positioning protrusion on the cup-lid encapsulation shell and an annular positioning groove on the adjustment knob that mates with it.

[0006] Furthermore, it also includes a rotating pin and a spring sleeved thereon; the rotating pin drives the adjustment knob to a potentiometer on the PCB control board, one end of the spring abuts against the knob seat, and the other end abuts against the shoulder of the rotating pin to provide axial preload.

[0007] Furthermore, the module base has a stepped shaft structure, with its large diameter section located inside the spool cover and its small diameter section extending out of the spool cover.

[0008] Furthermore, the module base is provided with an integrally formed protrusion that extends upward and passes through the PCB control board and the module cover, and is used to position and support the PCB control board.

[0009] Furthermore, the spool cover is provided with a coil mounting area for installing a brake coil; the module base is provided with a through hole for the fishing reel spool shaft to pass through, and the axis of the through hole is aligned with the center of the coil mounting area.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) By setting up mutually cooperating module bases and module covers, the core PCB control board is packaged into an independent and well-protected module unit, which not only greatly simplifies the assembly process on the production line, but also makes subsequent maintenance and replacement extremely convenient, thereby improving production efficiency and product maintainability.

[0012] (2) By cleverly setting the first and second sealing rings, a double waterproof barrier is formed at the key positions of the adjustment knob and the module cover, which can effectively prevent moisture and dust from entering from the external operation port, ensuring that the internal PCB control board and potentiometer and other core electronic components can still work stably for a long time in harsh environments such as humidity and dust, greatly improving the durability and reliability of the product.

[0013] (3) By setting an annular positioning protrusion on the cup lid packaging shell and precisely matching it with the annular positioning groove on the adjustment knob, a stable and reliable radial support is provided for the adjustment knob, which effectively avoids the shaking, eccentricity and jamming of the knob during rotation, ensuring smooth and accurate adjustment, and bringing users a clear, stable and high-quality operating feel.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, embodiments of this utility model are described below in detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] Please refer to Figures 1 to 7 This utility model embodiment provides a brake assembly mechanism for a teardrop fishing reel.

[0026] like Figure 1 and Figure 2 As shown, the overall structure, from the outside in, mainly includes a cup lid enclosure 1, a spool lid 2, and a highly integrated brake module installed inside the spool lid 2. This brake module is the core of the structure and mainly consists of a module base 4, a PCB control board 5, and a module cover 3. The adjustment knob 6 is the user-operated component, part of which protrudes through the knob adjustment port 15 of the cup lid enclosure 1.

[0027] Please refer to Figure 1 , Figure 3 and Figure 7The design of the brake module is a key feature of this embodiment. The module base 4 serves as the foundation for the module, and its interior contains a control board mounting slot 17 for housing the PCB control board 5. To ensure precise positioning and stable support of the PCB control board 5, the control board mounting slot 17 is equipped with several connection holes. The cup-lid encapsulation shell 1 is provided with several protrusions (not individually labeled in the figure). These protrusions extend downwards and pass through the cup-lid 2, then through the edge notches of the module cover 3 and the PCB control board 5, and finally mate with the connection holes in the control board mounting slot 17. At this point, the two can be connected by bolts, achieving structural fixation and ensuring the stable stacking of components in the Z-axis direction. Simultaneously, the module cover 3 covers and is detachably fixed to the module base 4, thus completely encapsulating the delicate and fragile PCB control board 5 within a separate, protected modular cavity. This design greatly simplifies the assembly process and facilitates maintenance.

[0028] Reference Figure 3 and Figure 4 To achieve reliable waterproofing and protect the internal PCB control board 5 from moisture corrosion, this mechanism features a sophisticated double-sealing structure. The core components of this structure are the first sealing ring 12 and the second sealing ring 13. The rotation of the adjustment knob 6 is supported by a knob base 7 located on the outside of the module cover 3. The first sealing ring 12 is positioned between the inner side of the adjustment knob 6 and the outer periphery of the knob base 7, forming the first waterproof barrier, primarily preventing moisture from entering through the gap between the adjustment knob 6 and the knob base 7. The second sealing ring 13 is positioned between the base of the knob base 7 and the contact surface of the module cover 3, forming the second waterproof barrier. These two sealing barriers work together to form a tight waterproof system, effectively preventing external water, moisture, or dust from entering the brake module.

[0029] Reference Figure 4 , Figure 5 and Figure 6 To improve the operating feel and prevent wobbling or eccentricity when the adjustment knob 6 is rotated, this mechanism also features a precise radial limiting structure. Specifically, an annular positioning protrusion 16 is integrally formed on the inner wall of the cup lid casing 1, surrounding the knob adjustment port 15. Correspondingly, an annular positioning groove 14 is formed on the outer peripheral wall of the adjustment knob 6. In the assembled state, the annular positioning protrusion 16 fits perfectly into the annular positioning groove 14. When the user rotates the adjustment knob 6, the sliding cooperation between the protrusion and the groove provides stable and reliable radial support for the knob, ensuring smooth and stable rotation, avoiding jamming, and providing an excellent operating experience.

[0030] Reference Figure 4The rotation of the adjustment knob 6 needs to be transmitted to the potentiometer on the PCB control board 5. This transmission is accomplished by a rotating pin 8. The rotating pin 8 passes through the knob seat 7 and the module cover 3 in sequence. One end of its rotation is fixedly connected to the adjustment knob 6, and the other end is connected to the adjustment part of the potentiometer on the PCB control board 5. To provide a certain degree of operational damping and feedback force, a spring 11 is also fitted on the rotating pin 8. The spring 11 is located in the shaft hole of the module cover 3, with one end abutting against the inner bottom surface of the knob seat 7 and the other end abutting against a specially provided shoulder on the rotating pin 8. The preload of the spring eliminates axial play, making the adjustment feel more precise.

[0031] Reference Figure 3 and Figure 7 To achieve the braking function in conjunction with the fishing reel's spool, the spool cover 2 has a recessed coil mounting area 9 for mounting the braking coil. Simultaneously, a through hole 10 is provided at the center of the module base 4. During use, the fishing reel's spool shaft (with an electromagnet fixed to it) passes through this through hole 10, ensuring the electromagnet is precisely within the magnetic field range of the coil mounted in the coil mounting area 9, thus achieving electromagnetic braking. Furthermore, during application, the fishing reel's spool shaft is supported and mounted within the through hole of the module base via bearings. The overall shape of the module base 4 is designed as a stepped shaft structure (e.g., ...). Figure 7 Its large-diameter section is located inside the cup cover 2, providing a stable mounting base, while the small-diameter section extends out of the cup cover 2, making the whole structure compact and reasonable.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
