Description

Technical Field

[0001] This utility model relates to a brake adjustment mechanism, and more particularly to a water droplet wheel brake adjustment mechanism and a water droplet wheel. Background Technology

[0002] Traditional baitcasting reel brake adjustment mechanisms primarily employ friction drives, spur gear drives, and linkage drives. Friction drives rely on spring preload to maintain contact pressure, which is prone to elasticity decay over time, and sliding friction can lead to accuracy errors. Spur gear drives suffer from concentrated meshing stress, easily causing tooth surface yielding, especially under aggressive operation where the contact stress exceeds the material's yield limit, significantly reducing lifespan. Furthermore, the sudden engagement / disengagement of gears in spur gear drives generates periodic impact noise, affecting the user experience. The biggest drawback of linkage drives is the accumulation of clearance between moving parts, leading to idle travel and affecting adjustment accuracy. Therefore, an innovative transmission structure is urgently needed that can simultaneously achieve high-precision adjustment, strong shock resistance, and excellent durability to meet the stringent requirements of professional fishing scenarios.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example 1;

[0021] Figure 1 and Figure 3The teardrop wheel brake adjustment mechanism shown includes an adjustment knob 1, a side cover 2, a spool cover 3, and a gear adjustment cover 4. The adjustment knob 1 is fitted into the opening of the side cover 2 via an outer annular step. The spool cover 3 is fitted inside the side cover 2, and the gear adjustment cover 4 is fitted inside the spool cover 3. The fitting relationship of these components only needs to satisfy a basic shape matching relationship; therefore, the basic shape of each component is not limited, and theoretically, a fitting relationship is sufficient. A spool switch 6 is rotatably fitted around the outer circumference of the spool cover 3 for installation and removal from the teardrop wheel. In some other embodiments, to further simplify the structure, screws can be used instead of the spool switch. Furthermore, in this embodiment, in addition to the reserved position for installing the adjustment knob, a transparent light fixture can also be embedded in the side cover 2.

[0022] like Figure 1 and Figure 2 The annular step surrounding the adjustment knob 1 has at least two steps, with the outer diameter of the higher step being smaller than that of the lower step. When the adjustment knob is fitted into the opening of the side cover 2 via the annular step, the lower step restricts the axial outward movement of the adjustment knob, primarily to prevent the adjustment knob from detaching from the side cover 2. The interior of the adjustment knob 1 forms an inner cavity with a single-sided opening. At the center of this cavity is a ring gear 11 that rotates circumferentially synchronously with the adjustment knob. Note that the center should be the same axis of rotation as the ring gear and the adjustment knob. The adjustment gear 41 on the gear adjustment cover 4 extends towards the reel cover 3 and, after passing through the opening on the reel cover 3, meshes with the circumferentially rotating ring gear 11. This forms a transmission mechanism where the ring gear meshes with the adjustment gear. Figure 4 The diagram shows the meshing state of the adjusting gear 41 and the ring gear 11.

[0023] The use of a ring-shaped internal gear and gear meshing transmission offers advantages such as high load capacity, long service life, simplified structure, high reliability, and low noise operation. The ring-shaped internal gear has a thicker tooth root and can mesh with multiple gear teeth simultaneously, evenly distributing the load across all contact points. This effectively avoids localized wear caused by single-point stress, significantly improving load capacity and service life. When the internal gear meshes with the external gear, they rotate in the same direction, eliminating the need for an additional reversing mechanism. This simplifies the transmission system, reduces potential failure points, and makes the overall structure more compact and reliable. The internal gear's tooth profile primarily features a concave design, resulting in a large contact area and less impact during meshing. Compared to traditional spur gears, the continuous, progressive meshing of the internal gear reduces impact energy, resulting in smoother operation, lower noise, and a better user experience.

[0024] like Figure 2 and Figure 3As shown, based on the above scheme, in order to limit the rotation range of the knob and prevent over-adjustment, a protrusion 12 is provided at the end of the adjustment knob 1 protruding towards the reel cover 3. A limiting block 31 is provided at each end of the arc-shaped movement path of the protrusion 12 on the end face of the reel cover 3 facing the protrusion 12. An arc-shaped partition 32 is provided on the end face of the reel cover 3, surrounding the limiting block 31 and the periphery of the movement path of the protrusion 12. The protrusion of the adjustment knob cooperates with the limiting block of the reel cover. The arc-shaped partition surrounds the movement path of the protrusion, providing physical isolation and further preventing gear misalignment caused by misoperation or external force. Therefore, this structure limits the rotation range by mechanically interfering with the protrusion 12 at the end of the adjustment knob 1 and the limiting block 31 on the reel cover 3. When the knob rotates, the protrusion 12 moves along the arc path and makes physical contact with the limiting blocks 31 on both sides when it reaches the set angle, preventing the protrusion 12 from moving further, thereby precisely limiting the maximum rotation angle of the knob. At the same time, the arc-shaped partition 32 surrounds the entire movement path to form a protective zone, which not only prevents interference from external foreign objects, but also ensures that the protrusion 12 can only move within the range defined by the limiting block 31, thus doubly ensuring the reliability of the adjustment range.

[0025] like Figure 1 As shown, the adjusting gear 41 is rotatably mounted inside the gear seat 42 of the gear adjusting cover 4. The end of the adjusting gear 41 that passes through the gear seat 42 has a slotted tooth. A circuit board 5 is installed inside the gear adjusting cover 4, and the electromagnetic precision adjustment knob of the circuit board 5 engages with the slotted tooth. When the teardrop wheel brake adjustment mechanism of this embodiment is working, the user rotates the adjusting knob 1 to drive its annular internal gear 11 to rotate. The internal gear 11 meshes with the adjusting gear 41 on the gear adjusting cover 4, causing the adjusting gear 41 to rotate synchronously. The slotted tooth at the end of the adjusting gear 41 drives the electromagnetic precision adjustment knob of the circuit board 5, thereby changing the parameter settings of the electronic brake system. At the same time, the protrusion 12 of the adjusting knob 1 cooperates with the limiting block 31 on the wheel cover 3 to limit the rotation range, and the arc-shaped partition 32 provides additional protection to ensure that the adjustment process is stable and reliable and to avoid gear disorder caused by external force interference. The entire transmission system achieves efficient and precise force transmission through the meshing design of the internal gear and the gear, simplifying the structure while improving durability and anti-interference ability.

[0026] Example 2;

[0027] This patent provides a teardrop wheel with an integrated electronic braking system. Its core lies in the organic combination of the brake adjustment mechanism from Embodiment 1 and an electromagnetic braking system. The teardrop wheel includes an adjustment knob 1, a side cover 2, a reel cover 3, a gear adjustment cover 4, a circuit board 5, a copper wire coil 7, a front cover 8, a magnet 9, and a spool 10. During operation, rotating the adjustment knob 1 drives the electromagnetic adjustment mechanism on the circuit board 5 through the meshing of the annular internal gear 11 and the adjustment gear 41, achieving precise setting of braking parameters. When the spool 10 rotates, it causes the magnet 9 to cut the magnetic field of the copper wire coil 7, generating an induced current. After processing by the circuit board 5, this current forms a controllable electromagnetic resistance, and the braking force can be changed by adjusting the knob's position. The internal gear meshing structure ensures stable transmission, and the double limit design (limiting block 31 and arc-shaped partition 32) prevents over-adjustment, making the speed adjustment process more reliable and durable.

[0028] The innovation of this system lies in its perfect combination of mechanical transmission and electronic control. Through the linkage between the adjustment knob with internal gears and the gears of the electronic brake intelligent device, the program parameters of circuit board 7 can be precisely controlled. When the spool 10 rotates, the current generated by the interaction between magnet 9 and copper wire coil 8 is used for both brake control and status visualization via transparent light fixture 5.

[0029] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
