Description

Technical Field

[0001] This utility model relates to a fishing reel line release control mechanism, and more particularly to an electromagnetic brake mechanism and a fishing reel. Background Technology

[0002] Bait reels are a type of horizontal reel primarily used for lure fishing, hence they are sometimes called lure reels. Compared to spinning reels, which are also fishing reels, bait reels offer higher casting accuracy and are smaller in size. However, line tangling is a frequent problem when anglers use bait reels. This is because the rotation speed of the reel and the amount of line being released during casting are not synchronized. When the bait enters the water, or during the bait's flight, changes in wind force or direction, or sudden gusts, slow the bait's flight speed while the reel continues to rotate due to inertia, causing a large amount of slack line to remain on the reel, resulting in knots and tangles in the spool and line. Traditional manual braking mechanisms use strong magnets to reduce line tangling, but this is not only complex to operate but also reduces casting distance, negatively impacting the fishing experience.

[0043] This utility model provides an electromagnetic braking mechanism and a fishing reel.

[0044] Reference Figures 1 to 14In one embodiment of the present invention, the electromagnetic braking mechanism includes a spool 1, the spool 1 having a spool body 11, the spool body 11 being an annular shape with both ends protruding outward along the circumferential direction, and a support seat 12 being provided inside, and a spool shaft 13 being provided on one side of the support seat 12, the cavity formed by the spool shaft 13, the support seat 12, and the inner wall of the spool body 11 being the spool shaft cavity 14.

[0045] In this embodiment, a multi-stage magnet 2 is provided, which is a ring magnet and is sleeved on the wire cup shaft 13 and fixedly connected to it.

[0046] In this embodiment, there are also a brake mechanism housing 3, a brake mechanism coil 4, a brake mechanism circuit board 5, a brake mechanism upper cover 6, a reel seat 7, a magnetic ring 8, and a gear adjustment knob 9.

[0047] like Figure 7 and Figure 8 As shown, the brake mechanism housing 3 is generally T-shaped and annular, comprising an upper housing 31 and a lower housing 32, which are integrally formed or fixedly connected. The bottom of the lower housing 32 is concave inward and convex, forming a housing ring 321. A coil cavity 33 is formed between the housing ring 321 and the upper and lower housings 31. The upper housing 31 also has three housing connecting parts 311 along its circumference.

[0048] The brake mechanism housing 3 is placed inside the spool cavity 14 and sleeved around the multi-stage magnet 2. Specifically, the lower housing 32 of the brake mechanism housing 3 is placed inside the spool cavity 14, but the bottom of the lower housing 32 does not contact the support seat 12 at the bottom of the spool cavity 14. The inner diameter of the housing ring 321 is larger than the outer diameter of the multi-stage magnet 2, and the housing ring 321 is sleeved around the multi-stage magnet 2. The brake mechanism coil 4 is circularly placed in the coil cavity 33 formed between the housing ring 321, the upper housing 31, and the lower housing 32.

[0049] In this embodiment, a brake mechanism circuit board 5 is provided above the inner bottom surface of the upper housing 31, such as... Figure 9 As shown, the brake mechanism circuit board 5 includes a gear adjustment sensor 5A, a microprocessor 5B, a power regulator 5C, a first electronic switch 5D, a second electronic switch 5E, a speed sensor 5F, a first coil pad 5G, a second coil pad 5H, and a rectifier filter 5I. The brake mechanism circuit board 5 also has three circuit board connection parts 51 along its circumference, each corresponding to one of the three housing connection parts 311. This allows the brake mechanism housing 3 to limit the brake mechanism circuit board 5, preventing its rotation. The components and functions of the circuit board 5 are all existing technology and are the same as the circuit control of existing electromagnetic brakes; therefore, they will not be described in detail here.

[0050] In this embodiment, a brake mechanism cover 6 is also provided inside the upper housing 31, such as... Figure 10 As shown, the brake mechanism upper cover 6 has three upper cover connecting parts 61 along its circumference, and a gear adjustment sensor passage groove 62 is also provided on the outer side of the circumference. The brake mechanism upper cover 6 is located on the upper housing 31 and above the brake mechanism circuit board 5, with its top flush with the top of the upper housing 31. The three upper cover connecting parts 61 correspond one-to-one with the three outer housing connecting parts 311. The fitting relationship between the brake mechanism upper cover 6 and the brake mechanism outer housing 3 is as follows: Figure 11 As shown.

[0051] In another embodiment, the top cover 6 can be omitted, and the brake mechanism circuit board 5 can be sealed directly by filling the upper housing 31 with glue.

[0052] In this embodiment, the reel seat 7 is sleeved on the outer periphery of the upper housing 31 and positioned opposite to the spool 1. For example... Figure 12 and Figure 13 As shown, the reel holder 7 has three reel holder connecting parts 71 facing downwards inside. These three connecting parts 71 are inserted into the connecting holes 312 of the three outer casing connecting parts 311 to form a fixed connection. The top of the reel holder 7 also has a knob placement groove 72, in which the gear adjustment knob 9 is located. Adjacent to the knob placement groove 72 on the top of the reel holder 7 is a reel holder limiting post 73, with retaining grooves 74 on both sides of the limiting post 73. Adjacent to the limiting post 73, the reel holder 7 also has a sensor through hole 75, through which the gear adjustment sensor 5A passes through the gear adjustment sensor through groove 62 and is located in the sensor through hole 75.

[0053] In this embodiment, as Figure 14 As shown, the bottom surface of the gear adjustment knob 9 is provided with a magnetic ring fixing seat 91. The magnetic ring 8 is located inside the magnetic ring fixing seat 91 and fixedly connected to it. The magnetic ring is sleeved on the outside of the limiting post 73 of the threaded wheel seat, so that the gear adjustment sensor 5A is located on the outside of the magnetic ring 8. The magnetic ring 8 is a radially magnetized magnet. When the magnetic ring 8 rotates, the gear adjustment sensor 5A will sense changes in magnetic field strength of different intensities. The bottom surface of the gear adjustment knob 9 also has an arc-shaped stop 92 along its circumferential edge. When the gear adjustment knob 9 is turned by hand, the two retaining grooves 74 on the threaded wheel seat 7 are used to block the two ends of the stop 92, thereby limiting the rotation angle of the gear adjustment knob 9.

[0054] In this embodiment, more preferably, the magnetic ring 8 can be sleeved on the outside of the magnetic ring fixing seat 91, and the magnetic ring fixing seat 91 can be sleeved on the limiting post 73 of the reel seat. Furthermore, the radially magnetized magnetic ring 8 can be any arc-shaped magnet, magnetized in a 1:1 ratio, with the N and S poles each occupying half after magnetization. It can also take specific shapes such as a ring, tile, fan, cylinder, or disc. In use, the side of the arc-shaped magnet is aligned with the front of the gear adjustment sensor 5A. When the arc-shaped magnet rotates under the action of the gear adjustment knob 9, the magnetic flux density of the gear adjustment sensor 5A changes accordingly. The output voltage signal changes proportionally to the magnetic flux density, and the microprocessor 5B can acquire the signal to determine the current gear position of the gear adjustment knob 9.

[0055] In this embodiment, the gear adjustment knob 9 is fixedly connected to the magnetic ring 8. By rotating the gear adjustment knob 9, different changes in magnetic field strength are detected. The ultimate goal is to achieve relative rotation between the magnetic ring 8 and the gear adjustment sensor 5A. Further, preferably, this invention can also fix the gear adjustment knob 9 to the brake mechanism circuit board 5, with the magnetic ring 8 fixed in one position. The gear adjustment knob 9 and the brake mechanism circuit board 5 further drive the gear adjustment sensor 5A to rotate, thereby detecting changes in magnetic field strength.

[0056] The gear shift sensor 5A is a proportional linear Hall effect magnetic sensor, which can respond proportionally to magnetic flux density for precise position detection. The specific operating principle of this invention is as follows:

[0057] (1) Working principle of gear adjustment mechanism:

[0058] The gear adjustment knob 9 is fixedly connected to the magnetic ring 2, which is a radially magnetized magnet. When the gear adjustment knob 9 is rotated, the magnetic ring 2 rotates accordingly, and the magnetic field strength changes accordingly. The gear adjustment sensor 5A on the brake mechanism circuit board 5 senses the magnetic field strength and linearly outputs a voltage to the microprocessor 5B based on the magnetic field strength. The microprocessor 5B executes the corresponding gear program according to the preset voltage-gear correspondence, thereby adjusting the braking force.

[0059] (2) Working principle of magnetic power generation:

[0060] A multipole magnet 2 is mounted on the spool shaft 13 of the spool 1. When the spool 1 rotates, the multipole magnet 2 rotates accordingly. The alternating magnetic field of the multipole magnet 2 cuts the brake mechanism coil 4, generating an induced current within the brake mechanism coil 4. This induced current is connected to the first coil pad 5G and the second coil pad 5H within the brake mechanism circuit board 5. The induced current passes through a rectifier filter 5I and then enters a 5C power regulator, outputting DC power to supply the internal circuitry of the brake mechanism circuit board 5.

[0061] (3) Working principle of electromagnetic brake:

[0062] Once the fishing reel starts working, the speed sensor 5F inside the brake mechanism circuit board 5 will monitor the rotational speed of the spool 1 in real time. The microprocessor 5B will adjust the braking force according to the current gear, and ultimately control the opening and closing ratio of the first electronic switch 5D and the second electronic switch 5E, thereby controlling the magnitude of the braking force.

[0063] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
