Abstract
Description
Technical Field
[0001] This utility model relates to a fishing reel. Background Technology
[0002] Electromagnetic braking is a common braking method in existing fishing reels. It primarily involves placing a magnet inside the reel body. By changing the distance between the spool and the magnet, the strength of the magnetic field is adjusted, thus regulating the braking force on the spool. However, this braking method has a relatively complex mechanical structure, requiring a lifting mechanism to adjust the distance between the spool and the magnet. Summary of the Invention
[0003] In order to overcome the above-mentioned shortcomings in the prior art, this utility model provides a fishing reel that brakes by changing the magnitude of the magnetic field strength by changing the magnitude of the current.
[0004] This utility model is achieved through the following technical solution:
[0005] An electromagnetically braked fishing reel includes a reel body and a spool mounted on the reel body. The spool is fitted onto the reel spindle and rotates with the spindle spindle. The reel spindle spindle is characterized by having a magnet mounted on it, rotating with the spindle spindle spindle. A coil is arranged around the radially outer periphery of the magnet, forming a closed loop. A continuously variable adjustment switch is provided on the closed loop. A toggle wheel is provided on the top cover of the reel body, and the toggle wheel is kinetically connected to the continuously variable adjustment switch.
[0006] Preferably, a coil frame is provided between the spool and the magnet on the main shaft of the reel. The coil frame is a slot-shaped structure with an open top. The coil is placed in the slot of the coil frame. A circuit board is provided in the upper opening of the coil frame. The coil is electrically connected to the circuit board. The stepless adjustment switch is located on the circuit board.
[0007] As a preferred embodiment, the stepless adjustment switch is provided with a knob, the surface of which is provided with a straight groove, the toggle wheel is provided with a toggle shaft, a spring is sleeved on the toggle shaft, and a straight protrusion is provided at the lower end of the toggle shaft, with the protrusion of the toggle shaft embedded in the groove.
[0008] Preferably, the top of the spool is provided with a top seat, the top cover is provided on the top seat, the actuating wheel is provided on the top seat and partially protrudes outside the top cover, and the actuating shaft on the actuating wheel passes through the top seat and is connected to the knob.
[0009] Preferably, the top cover has an opening on one side, and the shape of the opening matches the actuating wheel, with a portion of the actuating wheel protruding from the opening.
[0010] Preferably, the top seat has an arc-shaped groove, and the lower surface of the actuating wheel is provided with a first limiting block and a second limiting block at intervals. The first limiting block and the second limiting block are slidably disposed in the arc-shaped groove and are respectively limited to the two ends of the arc-shaped groove.
[0011] As a preferred option, the stepless adjustment switch is a potentiometer.
[0012] This invention involves placing a coil outside the magnet. When the main shaft of the spool rotates, it drives the magnet to rotate, causing the coil to rotate relative to the magnet, cutting the magnetic lines of force. The coil generates an induced current and an induced magnetic field, which cancels out the magnetic field of the magnet. By adjusting the magnitude of the induced current through a stepless adjustment switch, the magnitude of the induced magnetic field can be changed, thereby adjusting the force exerted by the magnetic field of the magnet on the spool, i.e., adjusting the braking force on the spool.
[0013] The beneficial effects of this utility model are as follows: This utility model utilizes the induced magnetic field generated by the rotation of the spool, and adjusts the braking force by adjusting its size. It only requires the addition of a coil and a circuit board, making the mechanical structure simpler. It also achieves a new way to adjust the braking force and enables stepless adjustment. The structure of this utility model is simple and reasonable. Attached Figure Description

[0018] The utility model will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0019] like Figure 1 , 2As shown in Figures 3 and 4, an electromagnetic braking fishing reel includes a main body and a spool 8 mounted on the main body. The spool 8 is fitted onto the main shaft 9 of the reel and rotates with the main shaft. A magnet 10 is also fitted onto the main shaft and rotates with it. When the main shaft 9 rotates, the spool 8 and the magnet 10 rotate simultaneously. Multiple coils 6 are arranged around the radial outer periphery of the magnet 10, forming a closed loop. A stepless adjustment switch 14 is installed on this closed loop. When the spool rotates relative to the magnet, it rotates relative to the coils. This is equivalent to the coils 6 cutting the magnetic lines of force generated by the magnet, thus generating an induced current. This induced current generates an induced magnetic field. The magnitude of the induced current is adjusted by the stepless adjustment switch, which is a potentiometer. By adjusting the resistance of the potentiometer, the magnitude of the induced current is adjusted, thereby changing the magnitude of the induced magnetic field. The induced magnetic field cancels out the magnetic field generated by the magnet. The change in the magnitude of the induced magnetic field changes the force exerted by the magnet on the spool, thus adjusting the braking force.
[0020] A coil holder 7 is installed between the spool and the magnet on the reel spindle. The coil holder 7 is a slot-shaped structure with an open top. The coil 6 is placed inside the slot of the coil holder. A circuit board 5 is installed inside the upper opening of the coil holder, and the coil is electrically connected to the circuit board. A stepless adjustment switch is located on the circuit board. The stepless adjustment switch 14 has a knob 15 with a groove on its surface. A toggle wheel 2 has a toggle shaft 13 with a spring sleeved on it. A groove-shaped protrusion 17 is located at the lower end of the toggle shaft, and the protrusion is embedded in the groove. The coil is located inside the coil holder, and the magnitude of the induced current is adjusted by toggling the knob of the stepless adjustment switch via the toggle wheel 2. The protrusion on the toggle shaft cooperates with the groove of the knob to achieve the toggle.
[0021] A top seat 4 is provided on the top of the spool, and a top cover 1 is provided on the top seat. The main shaft of the spool passes through the top seat and is connected to the top seat by a bearing. The coil frame is located below the top seat. The actuating wheel 2 is provided on the top seat and partially protrudes from the top cover 1. The actuating shaft 13 on the actuating wheel passes through the top seat and is connected to a knob on the circuit board. One side of the top cover has an opening, and the shape of the opening matches the actuating wheel, with part of the actuating wheel protruding from the opening. An arc-shaped groove 12 is provided on the top seat. A first limiting block 16 and a second limiting block 11 are provided at intervals on the lower surface of the actuating wheel. The first limiting block 16 and the second limiting block 11 are slidably disposed in the arc-shaped groove and are respectively limited to the two ends of the arc-shaped groove. During the actuation process, the actuating wheel is limited by the sliding distance of the first limiting block and the second limiting block in the arc-shaped groove of the top seat. When the first limiting block and the second limiting block respectively abut against the two ends of the arc-shaped groove 12, it can no longer rotate.
[0022] This invention involves setting a coil 6 outside the magnet 10. When the main shaft of the reel rotates, it drives the magnet to rotate, causing the coil to rotate relative to the magnet, cutting the magnetic lines of force. The coil generates an induced current and an induced magnetic field, which cancels out the magnetic field of the magnet. The magnitude of the induced current can be adjusted by using a stepless adjustment switch 14, thereby changing the magnitude of the induced magnetic field. This allows adjustment of the force exerted by the magnetic field of the magnet on the spool, i.e., adjusting the braking force on the spool.
[0023] This invention utilizes the induced magnetic field generated by the rotation of the spool to adjust the braking force. It only requires the addition of a coil and a circuit board, making the mechanical structure simpler. It also provides a new way to adjust the braking force and enables stepless adjustment. The structure of this invention is simple and reasonable.
