Description

Technical Field

[0001] This utility model relates to the field of fishing tackle technology, and in particular to an electromagnetic braking system for a fishing reel. Background Technology

[0002] Existing electromagnetic braking systems in fishing reels involve the spool rotating relative to the side cover during casting. A magnet on the spool and a coil module on the side cover generate electromagnetic induction. When the coil module is closed, it produces a magnetic field opposite to the magnet, thus hindering the spool's rotation. When the coil module is open, no magnetic field is generated, and the spool rotates unimpeded. Therefore, by inputting a fixed braking frequency to control the opening and closing of the coil module, the braking force can be controlled by changing the duty cycle of the braking frequency. However, with the development of fishing reels, inexperienced anglers, in different fishing scenarios, using different bait types and weights, and employing different casting techniques, cause significant fluctuations in the spool's rotation speed. This means that a fixed braking frequency cannot adapt to both low and high speeds. When the spool speed exceeds the control frequency, the braking response is delayed, leading to line breakage. When the spool speed is below the control frequency, the braking force is excessive, resulting in a short casting distance.

[0003] Therefore, there is an urgent need for an electromagnetic braking system for fishing reels that can differentiate between different reel speed ranges according to different scenarios, thereby adapting to low-speed or high-speed braking. Utility Model Content

[0004] The purpose of this invention is to provide an electromagnetic braking system for fishing reels, solving the technical problem in the prior art where the fixed braking frequency cannot be applied to both low and high speeds. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides an electromagnetic braking system for a fishing reel, comprising an electromagnetic component and a control component. The electromagnetic component is installed between the main shaft of the reel and a component base. The component base is connected to a reel seat, and the main shaft is rotatably connected to the reel seat. The system also includes: An adjustment knob is mounted on the control component and electrically connected to the electromagnetic component via the control component. Manually rotating the adjustment knob allows the electromagnetic component to adjust the rotational speed range of the reel. A light guide column is installed on the reel seat. The light source on the control component emits light according to the rotation speed of the reel, and the light guide column displays the emission status of the light source.

[0006] Preferred options also include: A component cover plate, which is fastened to the component base, and a control component is constrained between the component cover plate and the component base; An adjusting rod passes through the reel seat and the component cover plate, and is rotatably connected to the component cover plate. The adjusting rod rotates synchronously with the potentiometer knob on the control component, and the adjusting rod is engaged at the center of the adjusting knob.

[0007] Preferred options also include: A positioning block, which is positioned on the wheel seat, and an adjusting knob is rotatably connected to the positioning block; An arc-shaped groove and a slider are provided. The arc-shaped groove is formed on the positioning block, and the slider is fixed on the adjustment knob and slidably connected within the arc-shaped groove.

[0008] Preferred options also include: A side cover switch is sleeved on the reel seat and rotatably connected to the reel seat on the same axis. By manually rotating the side cover switch, the power to the control component is controlled to be turned on or off. A push handle is fixedly connected to the outer peripheral side of the side cover switch.

[0009] Preferably, the electromagnetic component includes: A coil, which is circumferentially mounted within the component base and electrically connected to the control component; A ring magnet is fixedly sleeved on the main shaft and located inside the coil.

[0010] Preferred options also include: Side cover, the reel seat is located between the side cover and the component base, the reel seat is connected to the side cover and is located between the component base and the side cover; A torsion spring is installed between the side cover switch and the side cover.

[0011] Preferably, the control component includes: A circuit board, the circuit board being placed inside the component base and confined between the component base and the component cover; A microcontroller and a Hall sensor are mounted on the circuit board and electrically connected to the coil.

[0012] Preferred options also include: An observation port and an operation port are respectively opened on the side cover. The adjustment knob is located inside the operation port, and the light guide column is located inside the observation port.

[0013] In the technical solution provided by this utility model, the main function of the adjustment knob is to adjust the strength of the induced electromagnetic field generated by the electromagnetic component, thereby producing different reel speed ranges. The stronger the induced electromagnetic field, the stronger the force resisting the reel's rotation, and vice versa. For different scenarios, a maximum speed value is limited within each reel speed range. Even inexperienced beginners can set different reel speed ranges by rotating the adjustment knob in different scenarios, thus limiting the maximum reel speed for that scenario. Once the control component receives a signal that the reel speed is trending towards exceeding the set value, it controls the electromagnetic component to generate an induced electromagnetic field of corresponding strength, thereby suppressing the reel's rotation. The light source on the control component emits light according to the reel's speed; the higher the reel's speed, the brighter the light source, and vice versa. The light guide column displays the light emission, allowing the angler to judge the line status by observing the reel's speed. Overall, the electromagnetic braking system of this application can distinguish different reel speed ranges according to different scenarios, thus adapting to low-speed or high-speed braking. Even inexperienced beginners can effectively avoid line tangling and breakage. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] refer to Figure 1-5 A specific embodiment of this utility model provides an electromagnetic braking system for a fishing reel, including an electromagnetic component and a control component. The electromagnetic component is installed between the main shaft 15 of the reel 14 and the component base 12. The component base 12 is connected to the reel seat 7. The main shaft 15 is rotatably connected to the reel seat 7. The system also includes: Adjustment knob 2 is mounted on the control component and is electrically connected to the electromagnetic component through the control component. Manually rotating adjustment knob 2 adjusts the rotational speed range of the reel 14 through the electromagnetic component. The light guide column 3 is installed on the reel seat 7. The light source on the control component emits light according to the rotation speed of the reel 14, and the light guide column 3 displays the light emission status of the light source.

[0019] With the development of fishing reels, inexperienced anglers may experience significant fluctuations in spool speed when casting in different fishing scenarios, using different bait types and weights, and employing different casting techniques. This means that a fixed braking frequency cannot adapt to both low and high spool speeds. When the spool speed exceeds the control frequency, the braking response may be delayed, leading to line breakage. Conversely, when the spool speed is below the control frequency, the braking force may be too great, resulting in a short casting distance. In this application, the main function of the adjustment knob 2 is to adjust the strength of the induced electromagnetic field generated by the electromagnetic component, thereby producing different rotational speed ranges for the reel 14. That is, the stronger the induced electromagnetic field, the stronger the force resisting the rotation of the reel 14, and vice versa. For different scenarios, the maximum rotational speed value is limited within each rotational speed range of the reel 14. Even inexperienced beginners can set different rotational speed ranges for the reel 14 by rotating the adjustment knob 2 in different scenarios, thus limiting the maximum rotational speed of the reel 14 in that scenario. Once the control component receives a signal that the rotational speed of the reel 14 tends to exceed the set value, it controls the electromagnetic component to generate an induced electromagnetic field of corresponding strength, thereby suppressing the rotation of the reel 14. The light source on the control component emits light according to the rotational speed of the reel 14. The higher the rotational speed of the reel 14, the brighter the light source, and vice versa. The light guide column 3 displays the light emission status, so that the angler can judge the line release status by observing the rotational speed of the reel 14. Overall, the electromagnetic braking system of this application can distinguish different speed ranges of the reel 14 according to different scenarios, thereby adapting to low-speed or high-speed braking. Even inexperienced novices can effectively avoid wire tangling and wire breakage.

[0020] Further optimization of the scheme also includes component cover plate 8 and adjusting rod 9. Component cover plate 8 is fastened to component base 12, and control component is restricted between component cover plate 8 and component base 12. Adjusting rod 9 passes through the reel seat 7 and component cover plate 8 and is rotatably connected to component cover plate 8. Adjusting rod 9 rotates synchronously with potentiometer knob on control component. Adjusting rod 9 is engaged at the center of adjustment knob 2.

[0021] refer to Figure 1 , 5 The main function of the component cover plate 8 is to confine the control component within the component base 12; the main function of the potentiometer knob is to adjust the current magnitude, thereby adjusting the strength of the induced electromagnetic field generated by the electromagnetic component. The adjusting rod 9 rotates synchronously with the potentiometer knob on the control component. By rotating the adjusting knob 2, the adjusting rod 9 is driven to rotate synchronously, thereby rotating the potentiometer knob.

[0022] Further optimization of the scheme also includes a positioning block 4, an arc-shaped slide groove 18, and a slider 17. The positioning block 4 is limited on the wheel seat 7, and the adjustment knob 2 is rotatably connected to the positioning block 4. The arc-shaped slide groove 18 is opened on the positioning block 4, and the slider 17 is fixed on the adjustment knob 2 and slidably connected in the arc-shaped slide groove 18.

[0023] refer to Figure 1 , 5 The main function of the positioning block 4 is to limit the rotation angle of the adjustment knob 2. Specifically, an arc-shaped groove 18 is provided on the positioning block 4. During the rotation of the adjustment knob 2, the slider 17 slides in the arc-shaped groove 18, which limits the rotation range of the adjustment knob 2 and also ensures the rotation stability of the adjustment knob 2.

[0024] Further optimization of the scheme also includes a side cover switch 5 and a pusher 6. The side cover switch 5 is sleeved on the reel seat 7 and is rotatably connected to the reel seat 7 on the same axis. By manually rotating the side cover switch 5, the power supply of the control component can be turned on or off. The pusher 6 is fixedly connected to the outer side of the side cover switch 5.

[0025] refer to Figure 1 , 5 By rotating the side cover switch 5 in the forward direction, the control component and electromagnetic component are energized, and by rotating it in the reverse direction, they are reset. By rotating the side cover switch 5 in the forward direction again, the control component and electromagnetic component are de-energized, and by rotating it in the reverse direction, they are reset. The main function of the push handle 6 is to facilitate manual operation.

[0026] Further optimization of the scheme: the electromagnetic component includes a coil 11 and a ring magnet 13. The coil 11 is circumferentially installed in the component base 12 and is electrically connected to the control component; the ring magnet 13 is fixedly sleeved on the main shaft 15 and located inside the coil 11.

[0027] refer to Figure 5 After the fishhook is cast, the reel 14, the spindle 15 and the ring magnet 13 rotate synchronously. After the control component receives the speed signal, when the speed exceeds the limit range, the control component controls the coil 11 to be energized to generate an induced magnetic field, suppressing the speed of the reel 14 and controlling the speed of the reel 14 within the limit range.

[0028] As the ring magnet 13 rotates with the spool 14, the coil 11 generates an induced current in the magnetic field, which in turn generates an induced electromagnetic field. According to Lenz's law, this generates a torque that opposes the movement of the ring magnet 13, thus generating a torque (braking force) opposite to the rotation direction of the spool 14, thereby inhibiting the rotation of the spool 14.

[0029] Further optimization of the scheme also includes a side cover 1 and a torsion spring 16, a reel seat 7 located between the side cover 1 and the component base 12, the reel seat 7 being connected to the side cover 1 and located between the component base 12 and the side cover 1; and the torsion spring 16 being installed between the side cover switch 5 and the side cover 1.

[0030] refer to Figure 3-5When the side cover switch 5 is in the reset state, the torsion spring 16 is in the compressed state. Whenever the side cover switch 5 is manually operated to rotate forward, the torsion spring 16 is further compressed. After releasing the hand, the side cover switch 5 automatically resets.

[0031] In a further optimized design, the control components include a circuit board 10, a micro control unit, and a Hall sensor. The circuit board 10 is placed inside the component base 12 and confined between the component base 12 and the component cover plate 8. The micro control unit and the Hall sensor are mounted on the circuit board 10 and are electrically connected to the coil 11.

[0032] The micro control unit uses an STM32L010 MCU, and the Hall sensor is used to detect the rotational speed of the reel 14. The micro control unit is electrically connected to the Hall sensor to obtain the wire output speed based on the rotational speed of the reel 14, and controls the operation of the coil 11 based on the rotational speed and the wire output speed.

[0033] Further optimization of the scheme also includes an observation port and an operation port (not marked in the figure). The observation port and the operation port are respectively opened on the side cover 1, the adjustment button 2 is located in the operation port, and the light guide column 3 is located in the observation port.

[0034] refer to Figure 2 By observing the light-emitting behavior of the light guide column 3 through the observation port, the rotation speed of the thread wheel 14 can be determined to judge the thread output status; the rotation angle of the adjustment knob 2 can be adjusted according to different scenarios.

[0035] Overall, the electromagnetic braking system of the fishing reel in this application is used as follows: Manually turn the side cover switch 5 to turn on the power, and then turn the adjustment knob 2 according to the scene to limit the maximum speed of the reel 14. When the reel 14 exceeds the maximum speed, the brake will start. The bait pulls the fishing line out, causing the reel 14 to rotate. The ring magnet 13 also rotates accordingly. During rotation, the coil 11 cuts the magnetic lines of force, generating a sinusoidal voltage. This voltage is rectified and stepped down to power the sensing circuit and charge the energy storage element. When the reel 14 reaches a certain speed, the voltage reaches the preset operating requirements. The MCU reads the speed of the reel 14 detected by the Hall sensor and calculates the line release speed of the reel 14. When the difference between the speed of the reel 14 and the line release speed is greater than a preset threshold, a braking action is initiated, i.e., the control coil 11 is turned on to form a closed loop. Each coil 11 generates an induced electromagnetic field, producing a torque that inhibits the movement of the ring magnet 13, thereby inhibiting the rotation of the reel 14 and balancing the speed of the reel 14 and the line release speed. The conduction time can be controlled according to the actual speed of the reel 14 and the line release speed, i.e., the time to form a closed loop, and the braking force can be automatically adjusted (corresponding to different speed ranges).

[0036] For example, if the Hall sensor detects that the rotational speed of reel 14 changes from increasing to decreasing during line release, the braking force needs to be reduced. The braking force can enter a linear decreasing mode to make the rotational speed of reel 14 decrease more smoothly, achieving the purpose of casting farther. When the line release speed begins to decrease and the rotational speed of reel 14 decreases slowly and uniformly, if it encounters external environmental influences, such as crosswinds, headwinds, or tailwinds, the line release speed may suddenly increase or decrease. After the Hall sensor quickly detects the change in line release speed (sudden increase or decrease), the MCU controls the conduction time of coil 11 to increase the braking force, so that the line release speed and the rotational speed of reel 14 reach a balance, avoiding line breakage. When the bait enters the water, the fishing line stops releasing, but reel 14 continues to release line due to inertia, which may cause line breakage. At this time, the MCU controls the conduction time of coil 11 to apply maximum braking force, so that reel 14 decelerates until it stops, preventing line breakage.
