Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] The present application claims priority from Chinese patent
application No. 202011448807.3 filed on Dec. 9, 2020, the entire
content of which is incorporated herein by reference.
TECHNICAL FIELD
[0002] The present disclosure relates to the field of fishing
tackle, and in particularly to a magnetic braking mechanism, a
baitcast reel and a fishing tool.
BACKGROUND TECHNOLOGY
[0003] Fishing reel is one of the necessary fishing tackle for
fishing. The existing magnetic braking system of fishing reel can
only apply a constant braking force during casting. Therefore, it
is difficult to control the fishing reel when the rotation speed of
the spool is too fast, thereby causing backlashes. Moreover, it is
incapable of adjusting the braking force according to the rotation
speed of the spool, so that a longer casting distance cannot be
achieved.

the spool. Each of the metal plates is movably arranged on the base
body through one of the elastic pieces respectively, in order to

force or an elastic force of the elastic pieces.
[0012] Further, at least two sliding slots are provided on the base
body, and a stopper is provided in a middle part of each of the
sliding slots. Two sliding blocks are extended downward
respectively from two opposite ends of each of the metal plates,
and the two sliding blocks are both disposed in one of the sliding

DESCRIPTION OF THE EMBODIMENTS
[0025] The present disclosure will be further described below in
conjunction with the accompanying drawings and embodiments in order
to enable those of ordinary skill in the art to more clearly
understand the objectives, technical proposals, and advantages of
the present disclosure.
[0026] Referring to FIGS. 1 to 4, FIGS. 1 to 4 show a first
embodiment of the magnetic braking mechanism 1 of the present
disclosure. In the embodiment shown, the magnetic braking mechanism
1 includes a spool 10, a magnet assembly 20, and a magnetic braking
assembly 30. The magnet assembly 20 is arranged on a side of the
spool 10 for generating magnetic induction lines. The magnetic
braking assembly 30 is connected to the spool 10, and includes at
least two metal plates 301 and a centrifugal adjusting assembly
302. The metal plates 301 are disposed between the magnet assembly
20 and the spool 10, and the centrifugal adjusting assembly 302 is
used to automatically adjust the spacing between the metal plates
301 and an axis of the spool 10 according to the rotation speed of
the spool 10, so as to adjust the range of the magnetic induction
lines cut by the metal plates 301, thereby automatically adjusting
the braking force. In the magnetic braking mechanism 1 of the
present disclosure, the centrifugal adjusting assembly 302 may
automatically adjust the spacing between the metal plates 301 and
the axis of the spool 10, namely the position of the metal plates
301 away from the center, according to the rotation speed of the
spool 10 as the spool 10 rotates, so as to adjust the range of the
magnetic induction lines cut by the metal plates 301, thereby
automatically adjusting the braking force.
[0027] In some embodiments, the magnet assembly 20 includes a
magnet base 201 arranged on the side of the spool 10 and a magnetic
body 202 consisting of a plurality of magnets 2021. The magnetic
body 202 is disposed on the magnet base 201, and magnetic poles on
two facing sides of each two adjacent magnets 2021 are opposite.
Preferably, in the present embodiment, the magnets 2021 are sector
magnets, and the magnetic body 202 is a ring magnet. In some other
embodiments, the magnetic body 202 may be a semi-ring magnet or a
3/4 ring magnet. In an initial state of the magnetic braking
mechanism 1 of the present disclosure, the magnetic induction lines
formed by the magnetic body 202 are partially covered by the metal
plates 301, thus the braking force is at a minimum. As the rotation
speed of the spool 10 increases, the metal plates 301 move away
from the axis of the spool 10 in a radial direction under the
centrifugal force. Accordingly, a maximum braking force opposite to
the rotating direction of the spool 10 is generated by the metal
plates 301 cutting the magnetic induction lines when all the
magnetic induction lines formed by the magnetic body 202 are
covered by the metal plates 301, which may effectively prevent
backlashes of the fishing line due to the spool 10 rotating too
fast.
[0028] Referring to FIGS. 2 to 4, in some embodiments, the
centrifugal adjusting assembly 302 includes a base body 3021 and at
least two elastic pieces 3022. The base body 3021 is connected to
the spool 10. Each of the metal plates 301 is movably arranged on
the base body 3021 through one of the elastic pieces 3022
respectively, in order to move in a radial direction of the base
body 3021 under a centrifugal force or an elastic force of the
elastic pieces 3022. Preferably, in the present embodiment, the
elastic pieces 3022 are springs. Based on this design, the metal
plates 301 move away from the axis of the spool 10 in the radial
direction under the centrifugal force when the spool 10 is rotated
rapidly, so that the range of the magnetic induction lines cut by
the metal plates 301 is increased, and the braking force is
increased. Similarly, the metal plates 301 slowly returns to their
original positions under the force exerted by the elastic pieces
3022 when the rotation speed of the spool 10 is decreased, so that
the range of the magnetic induction lines cut by the metal plates
301 is reduced, and the braking force is decreased.
[0029] Specifically, in the present disclosure, the magnetic
braking assembly 30 includes four metal plates 301 and four elastic
pieces 3022, and the four metal plates 301 and elastic pieces 3022
are arranged on the base body 3021 around the center thereof.
Moreover, four sliding slots 3211 are provided on the base body
3021, and a stopper 3212 is provided in a middle part of each of
the sliding slots 3211. A sliding block 3011 is extended downward
from each of two opposite ends of the metal plate 301, and two
sliding blocks 3011 are both disposed in one of the sliding slots
3211 and located respectively on two sides of the stopper 3212. One
end of each of the elastic pieces 3022 abuts against the stopper
3212, and the other end abuts against the sliding block 3011 near
the axis of the spool 10 to drive the metal plates 301 to move in
the radial direction of the base body 3021.
[0030] Furthermore, the centrifugal adjusting assembly 302 also
includes a limiting block 3023 located between two adjacent metal
plates 301, and the limiting block 3023 is arranged at an edge of
the base body 3021 to limit a moving distance of the metal plates
301 in the radial direction of the base body 3021. Specifically, in
the present embodiment, a limiting base 3024 is located below and
connected to the base body 3021. An edge of the limiting base 3024
is extended upward to form four limiting blocks 3023. It should be
understood, the limiting blocks 3023 may also be formed directly on
an edge of the base body 3021.
[0031] Based on the above design, in the magnetic braking mechanism
1 of the present disclosure, the metal plates 301 move outward in
the radial direction under the centrifugal force when the spool 10
is rotated rapidly at the beginning of a casting process. The metal
plates 301 are stopped by the limiting blocks 3023 when the metal
plates 301 move to the edge of the base body 3021 under the
centrifugal force. At the same time, all the magnetic induction
lines generated between the magnetic body 202 are covered by the
metal plates 301, thus a maximum braking force that is opposite to
the rotation direction of the spool 10 is generated as the magnetic
induction lines are cut by the metal plates 301, which effectively
prevents the spool 10 from producing backlashes due to the fast
rotation speed. Whereas, at the end of the casting process, the
metal plates 301 slowly returns to their original position under
the action of the elastic pieces 3022 as the rotation speed of the
spool 10 is reduced, so that the area of the magnetic induction
lines covered by the metal plates 301 gradually decreases, which
reduces the braking force and slows down the decline of the
rotation speed of the spool 10, thereby increasing the casting
distance.
[0032] In some embodiments, the magnetic braking mechanism 1 also
includes a side cover assembly 40, the magnet assembly 20 is
arranged in the side cover assembly 40, and a rotating shaft 101 of
the spool 10 passes through the magnet assembly 20 and is placed in
the side cover assembly 40. Specifically, the side cover assembly
40 includes a side cover body 401 and a spool base 402 connected to
the side cover body 401, the rotating shaft 101 of the spool 10
passes through the magnet assembly 20 and is inserted in the spool
base 402. An adjusting knob 403, a first magnetic slider 404, and a
second magnetic slider 405 are disposed in order between the side
cover body 401 and the spool base 402, and one end of the adjusting
knob 403 is exposed outside the side cover body 401. The second
magnetic slider 405 is connected to connecting posts 2011 on the
magnet base 201 by screws 50, and each connecting post 2011 is
provided with a spring 60.
[0033] Referring to FIGS. 5 and 6, FIGS. 5 and 6 show a second
embodiment of the magnetic braking mechanism 1 of the present
disclosure. The present embodiment is different from the first
embodiment in that the specific structure of the magnet assembly 20
is different, and the rest is the same. In the present embodiment,
the magnet assembly 20 includes a magnet base 201 disposed on one
side of the spool 10 and a magnetic body 202 consisting of a
plurality of magnets 2021, and the magnetic body 202 is arranged on
the magnet base 201. Each of the magnets 2021 includes a first
magnet 2211 and a second magnet 2212 facing each other, and the
first magnet 2211 and the second magnet 2212 have opposite magnetic
poles. Preferably, in the present embodiment, the magnets 2021 are
sector magnets, and the magnetic body 202 is a ring magnet. In some
other embodiments, the magnetic body 202 may be a semi-ring magnet
or a 3/4 ring magnet. It can be understood that in the present
embodiment, the magnetic field formed by the magnetic body 202 is
different from that in the first embodiment. The range of the
magnetic induction lines cut by the metal plates 301 may also be
adjusted under the action of the centrifugal adjusting assembly,
thereby automatically adjusting the magnitude of the braking
force.
[0034] It can be understood, in other embodiments of the present
disclosure, a baitcast reel may also be provided, which includes a
reel main body and the magnetic braking mechanism in the first and
second embodiments described above. The spool and the magnetic
braking assembly in the magnetic braking mechanism may be assembled
in the reel main body, with the side cover assembly connected with
the reel main body. At the same time, a fishing tackle including
the above-mentioned baitcast reel may also be provided, and the
structure of the fishing tackle except for the baitcast reel may be
the same as that of conventional fishing tackle in the prior art.
For example, a fishing rod, fishing line and the like may be
provided, and the structure is well-known to those skilled in the
art and will not be repeated herein.
[0035] The above descriptions are merely preferred embodiments of
the present disclosure, and are not intended to limit the present
disclosure. Various equivalent changes and modifications may be
made by those skilled in the art on the basis of the
above-mentioned embodiments, and all equivalent changes or
modifications made within the scope of the claims shall fall within
the scope of protection of the present disclosure.
