Description

Technical Field

[0001] This invention relates to the field of fishing reel braking mechanism technology, and more specifically to a shaftless, sliding adjustable floating magnetic brake assembly and a micro-throwing brake system. Background Technology

[0002] As we all know, with the improvement of people's living standards, fishing has become a way for people to relax and unwind. With the increase in the number of anglers, the variety of lure fishing tackle on the market is also increasing. Fishing reels in the domestic and international markets are divided into two main categories: spinning reels and baitcasting reels (including drum reels). Spinning reels are easy to operate and have a long line-letting distance, but they are inconvenient to carry and not aesthetically pleasing. When letting out the line, the swivel has poor line control and is prone to tangling. When reeling in the line, the swivel forces the line into a dead angle, and the stronger the tension, the greater the friction, which can easily cause the line to curl and deform. Therefore, baitcasting reels are currently the most commonly used. Baitcasting reels are small in size and have accurate casting points. Because of their fast and accurate casting, they are very popular.

[0003] Existing baitcasting reels generally use magnetic braking mechanisms to control the rotation speed of the metal reel, such as publication number CN210695589U, entitled "A Suspended Magnetic Braking Mechanism for Fishing Reels." The basic principle of magnetic braking is that each magnet 3 in the braking mechanism has N and S poles, thus creating small magnetic fields between the magnets 3. The metal reel 11 is located within these magnetic fields. When the metal reel 11 begins to rotate, it cuts the magnetic field lines. According to Lenz's law, the metal reel 11 experiences a force opposite to its motion, hindering its rotation and thus slowing down its rotation speed. This matches the rotation speed of the metal reel 11 with the line release speed, preventing line breakage due to excessive release speed. For details, refer to the aforementioned prior art. Figure 1 and Figure 2 As shown, magnet 3 moves according to the speed of metal reel 11. That is, when metal reel 11 rotates at low speed, magnet base 2 (magnet 3 on it) experiences a smaller outward force, and the distance between magnet base 2 (magnet 3 on it) and metal reel 11 is larger. At this time, the braking force is smaller. Figure 1 As shown, when the metal spool 11 rotates at high speed, the magnet base 2 (with its magnet 3) experiences a greater outward force and moves closer to the metal spool 11. The distance between the magnet base 2 (with its magnet 3) and the metal spool 11 decreases, and the braking force increases. Figure 2 (As shown). In addition, the magnetic braking mechanism described above can also control the magnitude of the magnetic field by adjusting the distance between the magnet 3 and the metal wire wheel 11, thereby more effectively adjusting the rotation speed of the metal wire wheel 11 and thus more effectively controlling the wire breakage phenomenon.

[0004] However, some problems still exist in the above technology. For example, when the braking mechanism is working, the two magnet seats must move or not move at the same time, which makes it impossible to adjust the braking force more precisely. This results in the angler's casting distance decreasing when the braking force is too large, and increasing the casting distance when the braking force is too small, but this will directly cause the line to break. In other words, the adjustment range of the braking system is relatively narrow and cannot meet the needs of anglers of different levels, especially advanced anglers.

[0005] Therefore, how to provide a shaftless, sliding adjustable floating magnetic brake assembly and micro-casting brake system with a wide adjustment range to meet the needs of anglers of different skill levels is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a shaftless, sliding adjustable floating magnetic brake assembly and a micro-casting brake system with a wide adjustment range of the braking system, thereby meeting the needs of anglers of different skill levels.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A shaftless, sliding, adjustable floating magnetic brake assembly includes:

[0009] Magnet holder;

[0010] Multiple floating magnet seats are evenly distributed and floatingly mounted on the magnet frame. Each floating magnet seat has a magnet fixed on it, and a first limiting boss is fixed at the top of each floating magnet seat.

[0011] A rotating adjustment cover is rotatably connected to the magnet holder. Multiple second limiting protrusions are evenly distributed on the side of the rotating adjustment cover facing the floating magnet seat. When the rotating adjustment cover is rotated, the second limiting protrusions stop on the outside of the corresponding first limiting protrusions.

[0012] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a shaftless, slidingly adjustable floating magnetic brake assembly. When it is necessary to adjust the braking force, the rotating adjustment cover can be rotated so that the corresponding second limiting boss on the rotating adjustment cover stops outside the first limiting boss on the corresponding floating magnet seat, thus preventing the floating magnet seat from being in a floating state and restricting its participation in the braking operation. Therefore, this shaftless, slidingly adjustable floating magnetic brake assembly can control the number of floating magnet seats participating in the braking operation by rotating the adjustment cover, thereby increasing the adjustment range of the braking system, meeting the needs of anglers of different skill levels, and also improving the market competitiveness of the industry.

[0013] Furthermore, multiple mounting slots are evenly distributed on the outer side wall of the magnet holder. The two side wall surfaces of the mounting slot located at its slot opening are respectively the first sliding trajectory surface and the spring abutment surface. The side wall surface of the mounting slot opposite to its slot opening is the second sliding trajectory surface.

[0014] The floating magnet holder includes:

[0015] A base body, on which the magnet is fixed, and at the top of the base body, the first limiting boss is fixed. The base body can float in the mounting groove. A first sliding support block that slides in contact with the first sliding track surface is fixed on one side of the base body. A second sliding support block and a spring support block that slide in contact with the second sliding track surface are respectively fixed on the inner side wall of the base body. A spring positioning post is fixed on one side of the spring support block.

[0016] A compression spring, one end of which is sleeved on the spring positioning post and abuts against one side of the spring support block, and the other end abuts against the spring abutment surface.

[0017] The beneficial effects of adopting the above technical solution are as follows: When a certain floating magnet seat initially participates in the braking operation, the seat body will not bulge out of the mounting groove under the action of the compression spring. As the speed of the metal wire wheel rotates faster and faster, the magnet in the floating magnet seat will quickly move closer to the metal wire wheel. At this time, the first sliding support block slides along the first sliding track surface, the second sliding support block slides along the second sliding track surface, and the floating magnet seat slides outward and bulges out of the mounting groove. That is, the distance between the magnet and the metal wire wheel is shortened, the electromagnetic resistance on the metal wire wheel increases, and the metal wire wheel decelerates rapidly, thereby reducing the occurrence of wire breakage.

[0018] Furthermore, a limiting groove is formed on the spring contact surface, and a limiting block is fixed on the second sliding support block, with the limiting block being limited in the limiting groove.

[0019] The beneficial effects of adopting the above technical solution are: when the seat body slides outward and protrudes from the mounting groove, the limiting block is always limited in the limiting groove, thereby ensuring that the seat body will not fall out of the mounting groove, and ensuring that after the metal wire wheel stops rotating, the seat body can be reset back into the mounting groove under the action of the compression spring, ready for the next braking operation.

[0020] Furthermore, a magnet embedding groove is provided on the base, and the magnet is embedded in the magnet embedding groove.

[0021] The beneficial effect of adopting the above technical solution is that it makes it easy to assemble and disassemble the magnets.

[0022] Furthermore, a plurality of pin holes are evenly distributed on one side of the magnet holder, located inside the mounting groove, and a plurality of pin guide holes are evenly distributed on the rotating adjustment cover, which also includes a plurality of pins, the pins passing through the pin guide holes and being inserted into the pin holes.

[0023] The beneficial effect of adopting the above technical solution is that the pin setting can prevent the rotating adjustment cover from moving up and down.

[0024] Furthermore, the rotating adjustment cover has multiple limiting grooves evenly distributed on the side facing the base, and a limiting pin is installed on one side of the magnet frame, the head of which can be placed in the groove of the limiting groove.

[0025] The beneficial effect of adopting the above technical solution is that when the rotary adjustment cover is rotated, the limiting pin can abut against the corresponding limiting groove to achieve the limiting of the rotary adjustment cover after rotation.

[0026] Furthermore, a limiting pin hole is provided on one side of the magnet holder, and a limiting spring is also included. One end of the limiting spring is placed in the limiting pin hole, and the other end is sleeved on the limiting pin and abuts against the step surface at the head end of the limiting pin.

[0027] The beneficial effects of adopting the above technical solution are: the contact between the limiting pin and the limiting groove is elastic, making it easy for the limiting pin to enter and exit the limiting groove, so that the limiting pin will not be stuck in the limiting groove and unable to come out, thereby hindering the smooth rotation of the rotating adjustment cover.

[0028] This invention provides a micro-launch braking system, comprising:

[0029] A reel support frame, wherein through holes and bearing mounting holes are respectively opened on two opposite side walls of the reel support frame, and a first bearing is installed in the bearing mounting hole;

[0030] A metal wire reel is placed inside the wire reel support frame, and one end of the metal wire reel's shaft is inserted and connected to the inner ring of the first bearing, while the other end passes through the through hole. The metal wire reel has an active surface area.

[0031] A teardrop shell, the opening side of which contacts one side of the reel support frame with the through hole, a support frame is fixedly connected to the teardrop shell, a second bearing is fixedly connected to the support frame, and the other end of the rotating shaft is inserted into the inner ring of the second bearing.

[0032] The aforementioned shaftless, sliding adjustable floating magnetic brake assembly is mounted on the teardrop shell;

[0033] A driving component is disposed on the water droplet shell, and the driving component is used to drive the magnet frame to move closer to the working surface area.

[0034] The beneficial effects of adopting the above technical solution are: the driving component can drive the magnet frame to move closer to the working surface area, that is, the magnet moves to the working surface area. At this time, the distance between the magnet and the metal wire wheel is closer, the braking force is greater, and thus the high-speed rotation of the metal wire wheel is more effectively controlled, which can prevent the wire from breaking.

[0035] Furthermore, the support frame is provided with column holes evenly distributed, and multiple pushing columns are evenly fixed on the other side of the magnet frame, with the pushing columns arranged through the column holes;

[0036] The driving component includes:

[0037] An adjustment knob assembly is provided on the teardrop shell, and a push plate on the adjustment knob assembly is located on one side of the support frame. The push plate is fixedly connected to the column ends of a plurality of push columns.

[0038] A set of return springs, comprising multiple springs, are respectively sleeved on the corresponding push column, with the two ends of the return springs abutting against one side of the push plate and one side of the support frame, respectively.

[0039] The beneficial effects of adopting the above technical solution are as follows: when the adjustment knob assembly is rotated, the push plate on it can drive the magnet frame to move closer to the working surface area, and the return spring is compressed. At this time, the distance between the magnet and the metal wire wheel is shortened, which can increase the braking force. When it is necessary to reduce the braking force, the adjustment knob assembly is rotated in the opposite direction. The push plate is reset under the action of the return spring, which in turn drives the magnet frame to reset. The distance between the magnet and the metal wire wheel is lengthened, and the braking force is reduced.

[0040] Furthermore, the adjustment knob assembly includes:

[0041] An adjustment knob is rotatably mounted on a knob hole on the water droplet shell. Multiple slots are evenly distributed on the wall of the knob hole, and the outer side of the adjustment knob is the rotating side.

[0042] A drive plate, one side of which is detachably connected to the inner side of the adjustment knob, a retaining spring is fixed on one side of the drive plate, the retaining spring is elastically engaged with the retaining groove, and the other side of the drive plate has a first outer spiral drive surface and a first inner spiral drive surface.

[0043] The push plate has a second outer spiral driving surface and a second inner spiral driving surface, the first outer spiral driving surface is in contact with the second outer spiral driving surface, and the first inner spiral driving surface is in contact with the second inner spiral driving surface.

[0044] The beneficial effects of adopting the above technical solution are as follows: When the adjustment knob is rotated, it drives the drive plate to rotate together. The retaining spring and the retaining groove are elastically engaged to ensure that the position of the adjustment knob is fixed after rotation. During the rotation of the drive plate, the action of the first outer spiral drive surface and the second outer spiral drive surface, as well as the action of the first inner spiral drive surface and the second inner spiral drive surface, can push the push plate to move. Then, the push plate pushes the magnet frame closer to the metal wire wheel through the push column. The return spring is compressed, and the distance between the magnet and the metal wire wheel is shortened, which increases the braking force. When it is necessary to reduce the braking force, the adjustment knob is rotated in the opposite direction. The push plate is reset under the action of the return spring, which in turn drives the magnet frame to reset. The distance between the magnet and the metal wire wheel is lengthened, and the braking force is reduced.

[0045] Furthermore, one side of the drive plate is engaged with the inner side of the adjustment knob, the outer edge of one side of the drive plate has a stop protrusion, the retaining spring is engaged on the inner side of the stop protrusion, the retaining spring has a locking lug, and the locking lug is elastically engaged with the locking groove.

[0046] The beneficial effects of adopting the above technical solution are: the drive plate and the adjustment knob are engaged and matched, making it easy to install and remove the drive plate; and the retaining spring can be directly installed on the drive plate through the stop protrusion, making the retaining spring easy to install and remove.

[0077] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0078] See Figures 3-14 This invention discloses a shaftless, slidingly adjustable floating magnetic brake assembly, comprising:

[0079] Magnet holder 1;

[0080] Multiple floating magnet seats 2 are evenly distributed and floatingly installed on the outer side wall of the magnet frame 1. Each floating magnet seat 2 has a magnet 3 fixed on its outer side wall or top surface, and each floating magnet seat 2 has a first limiting boss 201 fixed on its top.

[0081] Rotary adjustment cover 4 is rotatably connected to magnet holder 1. Multiple second limiting protrusions 401 are evenly distributed on the side of the rotating adjustment cover 4 facing the floating magnet seat 2. When the rotating adjustment cover 4 is rotated, the second limiting protrusions 401 stop on the outside of the corresponding first limiting protrusions 201.

[0082] In the above embodiment, a plurality of mounting grooves 101 are evenly distributed on the outer side wall of the magnet frame 1. The two side wall surfaces of the mounting groove 101 located at its groove opening are the first sliding trajectory surface 1011 and the spring abutment surface 1012, respectively. The groove wall surface of the mounting groove 101 opposite to its groove opening is the second sliding trajectory surface 1013.

[0083] The floating magnet base 2 includes:

[0084] A base 21 is provided, with a magnet 3 fixed on its outer wall or top surface. A first limiting boss 201 is fixed on the top of the base 21. The base 21 can float in the mounting groove 101. A first sliding support block 211 that slides in contact with the first sliding track surface 1011 is fixed on one side of the base 21. A second sliding support block 212 and a spring support block 213 that slide in contact with the second sliding track surface 1013 are fixed on the inner side wall of the base 21. A spring positioning post is fixed on one side of the spring support block 213.

[0085] The compression spring 22 has one end sleeved on the spring positioning post and abuts against one side of the spring support block 213, and the other end abuts against the spring abutment surface 1012.

[0086] In the above embodiment, a limiting groove 10121 is formed on the spring contact surface 1012, and a limiting block 2121 is fixed on the second sliding support block 212, with the limiting block 2121 being limited in the limiting groove 10121.

[0087] In the above embodiment, a magnet embedding groove 2101 is provided on the outer side wall or top surface of the base 21, and the magnet 3 is embedded in the magnet embedding groove 2101.

[0088] In the above embodiment, a plurality of pin holes 102 are evenly distributed on one side of the magnet holder 1 at the inner position of the mounting groove 101, and a plurality of pin guide holes 402 are evenly distributed on the rotating adjustment cover 4, and a plurality of pins 5 are also included. The pins 5 pass through the pin guide holes 402 and are inserted into the pin holes 102.

[0089] In the above embodiment, a plurality of limiting grooves 403 are evenly distributed on the side of the rotating adjustment cover 4 facing the seat 21, and a limiting pin 6 is installed on one side of the magnet frame 1. The head of the limiting pin 6 can be placed in the groove of the limiting groove 403.

[0090] In the above embodiment, a limiting pin hole 103 is provided on one side of the magnet holder 1, and a limiting spring 7 is also included. One end of the limiting spring 7 is placed in the limiting pin hole 103, and the other end is sleeved on the limiting pin 6 and abuts against the head end stepped surface 8 of the limiting pin 6.

[0091] For details, see Figures 7-14 In the above-mentioned shaftless, sliding adjustable floating magnetic brake assembly, the principle of brake adjustment using three floating magnet seats as an example is explained below:

[0092] See Figure 7 When the rotating adjustment cover is not rotated, the first limiting bosses on all three floating magnet seats are not stopped inside the second limiting bosses. At this time, all three floating magnet seats can participate in the braking operation; that is, when the three floating magnet seats brake, they will all protrude outward from the magnet frame. Figure 14 As shown.

[0093] See Figure 8 Rotating the adjustment cover clockwise by 10° causes only the first limiting boss on one floating magnet seat to be positioned inside the second limiting boss. This means one floating magnet seat does not participate in braking, while the other two floating magnet seats participate in the braking action. In other words, when braking, both floating magnet seats will protrude outwards from the magnet holder. Figure 13 As shown.

[0094] See Figure 9 Rotating the adjustment cover clockwise by 20° causes the first limiting boss on each of the two floating magnet seats to be positioned inside the second limiting boss. This means that two floating magnet seats do not participate in the braking action, while the third floating magnet seat does. In other words, when only one floating magnet seat is engaged in braking, the magnet holder will protrude outwards. Figure 12 As shown.

[0095] See Figure 10 Rotating the adjustment cover clockwise by 30° causes the first limiting protrusions on all three floating magnet seats to stop inside the second limiting protrusions. This means that none of the three floating magnet seats participate in the braking operation; in other words, when braking, none of the three floating magnet seats will protrude outwards from the magnet holder. Figure 11 As shown.

[0096] This invention also discloses a micro-launch braking system, comprising:

[0097] The reel support frame 9 has through holes 901 and bearing mounting holes 902 respectively on its two opposite side walls. A first bearing 10 is installed in the bearing mounting hole 902.

[0098] Metal wire spool 11 is placed inside the wire spool support frame 9, and one end of the rotating shaft 12 of the metal wire spool 11 is inserted and connected to the inner ring of the first bearing 10, and the other end is arranged through the through hole 901. The metal wire spool 11 is provided with an action surface area 111.

[0099] The teardrop shell 13 has an opening side that contacts one side of the reel support frame 9 with a through hole 901. A support frame 14 is fixedly connected to the teardrop shell 13, and a second bearing 15 is fixedly connected to the support frame 14. The other end of the rotating shaft 12 is inserted into the inner ring of the second bearing 15.

[0100] The aforementioned shaftless, sliding adjustable floating magnetic brake assembly is mounted on the teardrop shell 13;

[0101] A drive component 16 is disposed on the water droplet shell 13. The drive component 16 is used to drive the magnet holder 1 to move closer to the working surface area 111.

[0102] For details, see Figures 15-29 The following is an embodiment of the driving component 16 of the present invention:

[0103] The support frame 14 has column holes 141 evenly distributed on it, and multiple push columns 104 are evenly distributed and fixed on the other side of the magnet frame 1. The push columns 104 are arranged through the column holes 141.

[0104] The driving component 16 includes: an adjustment knob assembly 161, which is disposed on the teardrop shell 13, and a push plate 1614 on the adjustment knob assembly 161 is located on one side of the support frame 14. The push plate 1614 is fixedly connected to the ends of multiple push columns 104; and a return spring 162, which is multiple and is respectively sleeved on the corresponding push column 104. The two ends of the return spring 162 abut against one side of the push plate 1614 and one side of the support frame 14.

[0105] Adjustment knob assembly 161 includes:

[0106] An adjustment knob 1611 is rotatably mounted on a knob hole 131 on the teardrop shell 13. Multiple slots 1311 are evenly distributed on the wall of the knob hole 131. The outer side of the adjustment knob 1611 is the rotating side. A drive plate 1612 is detachably connected to the inner side of the adjustment knob 1611 on one side. A retaining spring 1613 is fixed to one side of the drive plate 1612, elastically engaging with the slots 1311. The other side of the drive plate 1612 has a first outer spiral drive surface 16121 and a first inner spiral drive surface 16122. A push plate 1614 has a second outer spiral drive surface 16141 and a second inner spiral drive surface 16142. The first outer spiral drive surface 16121 contacts the second outer spiral drive surface 16141, and the first inner spiral drive surface 16122 contacts the second inner spiral drive surface 16142. One side of the drive plate 1612 is engaged with the inner side of the adjustment knob 1611. The outer edge of one side of the drive plate 1612 has a stop protrusion 16123. The retaining spring 1613 is engaged with the inner side of the stop protrusion 16123. The retaining spring 1613 has a locking lug 16131, which is elastically engaged with the locking groove 1311.

[0107] When maximum braking force is required, rotating the adjustment knob causes the drive plate to rotate as well. The retaining spring engages elastically with the retaining groove, ensuring the adjustment knob remains in its fixed position after rotation. During the rotation of the drive plate, the action of the first and second outer helical drive surfaces, as well as the action of the first and second inner helical drive surfaces, pushes the push plate to move. The push plate then pushes the magnet holder towards the metal wire wheel via the push column, meaning the magnet moves to the action surface area. The return spring compresses, shortening the distance between the magnet and the metal wire wheel, thus increasing the braking force (see...). Figure 29 Simultaneously, by rotating the adjusting cover, all the floating magnet seats are put into a braking state (see...). Figure 7 and Figure 14 At this point, the braking force is at its maximum. If the angler feels the braking force is too strong, they can fine-tune the rotating adjustment cover to adjust the number of floating magnet seats involved in the braking action. Specifically, remove the teardrop shell from the reel support frame, such as... Figure 18 and Figure 19 Then, rotate the adjustment cover clockwise. The corresponding second limiting boss stops on the outside of the first limiting boss on the corresponding floating magnet seat, so that the floating magnet seat is no longer in a floating state, limiting its participation in the braking work. In this way, the number of floating magnet seats participating in the braking work can be adjusted to achieve fine adjustment of the braking force.

[0108] Therefore, this micro-casting braking system not only allows adjustment of the braking force by adjusting the distance between the magnet and the metal reel using a knob, but also allows fine-tuning of the braking force by rotating the adjustment cover to control the number of floating magnet seats involved in the braking action. This expands the adjustment range of the braking system, meeting the needs of anglers of different skill levels and enhancing its market competitiveness. The floating magnet seat of this invention does not require connection to the magnet frame via a rotating shaft (as in existing technologies). Figure 1 and Figure 2 The magnet base is connected to the magnet frame via a pivot on one side, thus achieving a pivotless floating brake for the first time in a micro-casting braking structure, distinguishing it from any existing braking structure. Furthermore, it is the first micro-casting braking structure to feature an adjustable magnet base, again differentiating it from any existing braking structure. This invention's micro-casting braking system is the first to achieve a stable braking system usable by anglers of all skill levels, providing a stable platform for fishing enthusiasts and significantly increasing its competitiveness in the industry.
