Abstract
Description
Technical Field
[0001] This invention relates to the field of fishing tackle, and more specifically to a braking mechanism, a baitcasting reel, and fishing tackle. Background Technology
[0002] Fishing reels are an essential piece of fishing tackle for casting (sea fishing). Currently, most fishing reels use magnetic braking mechanisms. During casting, the reel spins at high speed due to the pull of the rapidly flying bait. This high-speed rotation cuts the magnetic lines of force around the magnet in the magnetic braking mechanism, generating an induced current. This creates a resistance force, commonly known as braking force, that acts in the opposite direction to the reel's motion when cutting the magnetic lines. This prevents the reel from accelerating too fast and its rotational speed from exceeding the bait's flight speed, thus avoiding line breakage. However, existing magnetic braking mechanisms can only provide a constant braking force during casting. That is, once the user adjusts the magnetic braking knob to a certain setting, only the reel's acceleration affects the magnitude of the resistance between the reel and the magnet. This single reel damping intervention means that, for the same fishing reel, line breakage often occurs depending on the user's casting technique, casting force, and / or the weight of the bait, especially for beginners. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a braking mechanism, a baitcasting reel, and fishing tackle that can automatically adjust the braking force according to the speed of the reel during the rotation of the reel.
[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, a braking mechanism is provided, comprising:
[0005] spool;
[0006] A magnetic brake assembly, located at one end of the reel, includes a magnet assembly and a centrifugal adjustment assembly. The magnet assembly generates magnetic field lines, and the centrifugal adjustment assembly automatically adjusts the distance between the magnet assembly and the end face of the reel according to the rotational speed of the reel, thereby adjusting the range of the reel cutting the magnetic field lines and thus automatically adjusting the braking force.
[0007] The further technical solution is as follows: the centrifugal adjustment component includes an elastic element and a cam, the magnet component includes a magnet base, a hollow magnet frame, and a magnet disposed on the magnet frame. The top surface of the magnet base has at least one sliding groove. The cam is disposed in the lower part of the magnet base, and the protrusion of the cam abuts against the inner wall of the magnet frame. The upper part of the magnet frame is movably disposed in the sliding groove through the elastic element, so that the magnet frame moves along the protrusion of the cam under the action of electromagnetic force or elastic force of the elastic element when the pulley rotates, thereby causing the magnet to move towards or away from the end face of the pulley.
[0008] The further technical solution is as follows: the cam is a helical cam, the top of the magnet frame is provided with at least one connecting post, each of the connecting posts is located in a slide groove and can move in the slide groove, one end of the elastic element is connected to a side wall of the slide groove, and the other end is connected to the connecting post, the inner wall of the magnet frame is provided with a connecting groove that matches the contour of the protrusion in the cam, so that when the magnet frame rotates under the action of electromagnetic force or elastic force of the elastic element, the groove wall of the connecting groove moves along the edge of the protrusion.
[0009] The further technical solution is as follows: the number of elastic elements, connecting columns and sliding grooves are all three, the three sliding grooves are arranged around the center of the magnet base, and each connecting column is movably disposed in one of the sliding grooves through an elastic element.
[0010] A further technical solution is as follows: the magnet assembly further includes at least one magnet attracting piece, which is fixed on the magnet frame and attracted to the top of the magnet.
[0011] The further technical solution is as follows: the magnetic attractant includes an attracting part, two extension plates extending upward from both ends of the attracting part, and two mounting plates bending outward from the outer side of the extension plates. The magnet frame is provided with at least one mounting groove. The attracting part of the magnetic attractant passes through the mounting groove and is attracted to the top of the magnet. The two mounting plates are located on the top surface of the magnet frame.
[0012] The further technical solution is as follows: the centrifugal adjustment assembly also includes a cam cover, the magnet seat includes a seat body and a connecting body extending downward from the middle of one side of the seat body, the slide groove is opened on the seat body, the cam is located on the connecting body, the cam cover is placed on the cam and fixed to the connecting body by screws.
[0013] The further technical solution is as follows: the braking mechanism further includes a side cover assembly, the magnetic braking assembly is disposed on the side cover assembly, and the spool shaft passes through the magnet assembly and is placed inside the side cover assembly.
[0014] To solve the above-mentioned technical problems, according to another aspect of the present invention, a baitcasting reel is provided, which includes a reel body and a braking mechanism connected to the reel body, wherein the braking mechanism is the aforementioned braking mechanism.
[0015] To solve the above-mentioned technical problems, according to another aspect of the present invention, a fishing tackle is provided, which includes the above-described baitcasting reel.
[0016] Compared with existing technologies, the centrifugal adjustment component in this invention automatically adjusts the distance between the magnet component and the end face of the spool according to the rotational speed of the spool. This allows the magnet component to move axially closer to or further away from the end face of the spool, thereby controlling the strength of the magnetic field lines near the end face of the spool. This adjusts the range of magnetic field lines cut by the end face of the spool, achieving the purpose of automatically adjusting the braking force. It is understood that in this invention, the spool can cut magnetic field lines through its end face when rotating, and the distance between the magnet component and the end face of the spool is variable. During casting, the distance between the magnet component and the end face of the spool can be changed according to the rotational speed of the spool, thus providing different levels of braking force. This allows the spool speed to be automatically fine-tuned to maintain a dynamic balance with the braking force, thereby reducing the probability of line breakage. Attached Figure Description

[0025] To enable those skilled in the art to more clearly understand the purpose, technical solution, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0026] Reference Figures 1 to 5 , Figures 1 to 5A specific embodiment of the braking mechanism 1 of the present invention is shown. In the embodiment shown in the figures, the braking mechanism 1 includes a reel 10 and a magnetic braking assembly 20 disposed at one end of the reel 10. The magnetic braking assembly 20 includes a magnet assembly 21 and a centrifugal adjustment assembly. The magnet assembly 21 is used to generate magnetic field lines, and the centrifugal adjustment assembly is used to automatically adjust the distance between the magnet assembly 21 and the end face 102 of the reel 10 according to the rotational speed of the reel 10, so as to adjust the range of the reel 10 cutting the magnetic field lines, thereby automatically adjusting the braking force. Based on the above design, when the reel 10 rotates, the braking mechanism 1 of the present invention can change the distance between the magnet assembly 21 and the end face 102 of the reel 10 according to the rotation speed of the reel 10, so that the distance between the magnet assembly 21 and the end face 102 of the reel 10 is variable. That is, the magnet assembly 21 can move axially under the action of the centrifugal adjustment assembly, moving closer to or further away from the end face 102 of the reel 10, so as to control the strength of the magnetic field lines near the end face 102 of the reel 10, thereby adjusting the range of the end face 102 of the reel 10 cutting the magnetic field lines, and then automatically adjusting the braking force, so that the rotation speed of the reel 10 can be automatically fine-tuned to maintain dynamic balance with the braking force, thereby reducing the probability of wire breakage.
[0027] In some embodiments, the centrifugal adjustment assembly includes an elastic element 221 and a cam 222. The magnet assembly 21 includes a magnet base 211, a hollow magnet frame 212, and a magnet 213 disposed on the magnet frame 212. The top surface of the magnet base 211 has at least one groove 2111. The cam 222 is disposed in the lower part of the magnet base 211, and the protrusion 2221 of the cam 222 abuts against the inner wall of the magnet frame 212. The upper part of the magnet frame 212 is movably disposed in the groove 2111 by the elastic element 221, so that the magnet frame 212 moves along the protrusion 2221 of the cam 222 under the action of electromagnetic force or elastic force of the elastic element 221 when the reel 10 rotates, thereby causing the magnet 213 to move toward or away from the end face 102 of the reel 10. Preferably, in this embodiment, the cam 222 is a helical cam, that is, the protrusions 2221 of the cam 222 are arranged in a helical shape along the axial direction.When the braking mechanism 1 of the present invention is assembled into the fishing reel body for use, during casting, the reel 10 rotates at high speed due to the pull of the rapidly flying bait. The reel 10 will experience a Lorentz force (braking force) opposite to its rotation direction due to the magnetic induction with the magnet 213. Under this braking force, the rotational speed of the reel 10 is reduced. During this process, according to Newton's third law, while the reel 10 is subjected to the Lorentz force, the magnet 213 will also experience a reaction force. This reaction force originates from the reel 10 and is directed opposite to the Lorentz force. Under the influence of an electromagnetic force in opposite directions, magnet 213 tends to follow the reel 10. Since magnet 213 is mounted on magnet holder 212, and the upper part of magnet holder 212 is movably mounted within the groove 2111 of magnet base 211 via elastic element 221, and the lower part of magnet holder 212 is also provided with a cam 222 that engages with the inner wall of magnet holder 212, when the electromagnetic force on magnet 213 is greater than the thrust of elastic element 221, the upper part of magnet holder 212 can move within the groove 2111, and through the inner wall of magnet holder 212 and the cam... The engagement of the protrusion 2221 in section 222 allows the magnet holder 212 to move along the trajectory of the protrusion 2221, resulting in axial displacement. This causes the magnet 213 to move closer to the end face 102 of the reel 10 under the influence of the magnet holder 212. In other words, as the speed of the reel 10 increases, the magnet 213 gradually approaches the end face 102 of the reel 10. Consequently, the magnetic flux density between the magnet 213 and the end face 102 of the reel 10 increases, increasing the braking force and providing greater braking power to suppress the rotation of the reel 10. The buffering effect slows down the rotation speed of the reel 10, effectively preventing the fishing line from tangling due to excessive rotation speed of the reel 10. At the end of the casting process, the rotation speed of the reel 10 decreases, the braking force decreases accordingly, and the electromagnetic force on the magnet 213 also decreases. When it weakens to less than the thrust of the elastic element 221, the magnet frame 212 moves in the opposite direction along the trajectory of the protrusion 2221, causing the magnet 213 to move away from the end face 102 of the reel 10 and eventually return to its original position. The intensity of the magnetic field line that the end face 102 of the reel 10 can cut is weakened, thereby reducing the braking force and increasing the casting distance.
[0028] Continue to refer to Figures 2 to 5In some embodiments, the top of the magnet frame 212 is provided with at least one connecting post 2121, each connecting post 2121 is located in a slide groove 2111 and can move within the slide groove 2111. One end of the elastic member 221 is connected to a side wall of the slide groove 2111, and the other end is connected to the connecting post 2121. The inner wall of the magnet frame 212 is provided with a connecting groove 2122 that matches the contour of the protrusion 2221 in the cam 222, so that when the magnet frame 212 rotates under the action of electromagnetic force or the elastic force of the elastic member 221, the groove wall of the connecting groove 2122 moves along the edge of the protrusion 2221. Based on the above design, combined with Figures 3 to 5 When the electromagnetic force on the magnet 213 increases to be greater than the thrust of the elastic element 221, the magnet frame 212 rotates under the action of the electromagnetic force. The groove wall of the connecting groove 2122 of the magnet frame 212 gradually moves downward along the contour edge of the protrusion 2221, so that the magnet 213 gets closer to the end face 102 of the spool 10. When the electromagnetic force on the magnet 213 decreases to be less than the thrust of the elastic element 221, the magnet frame 212 rotates in the opposite direction under the action of the elastic force. The groove wall of the connecting groove 2122 of the magnet frame 212 gradually moves upward along the contour edge of the protrusion 2221, so that the magnet 213 gradually moves away from the end face 102 of the spool 10.
[0029] Specifically, in this embodiment, the number of elastic elements 221, connecting posts 2121, and sliding grooves 2111 are all three. The three sliding grooves 2111 are arranged around the center of the magnet base 211. Each connecting post 2121 is movably disposed within a sliding groove 2111 via an elastic element 221, which is a spring. Preferably, the magnet 213 is an annular magnet. The centrifugal adjustment assembly further includes a cam cover 223. The magnet 213 base includes a base body 2112 and a connecting body 2113 extending downward from the middle of one side of the base body 2112. The sliding groove 2111 is formed on the base body 2112. The cam 222 is located on the connecting body 2113. The cam cover 223 covers the cam 222 and is fixed to the connecting body 2113 by screws 224.
[0030] Furthermore, in this embodiment, the magnet assembly 21 further includes three magnetic attracting pieces 214, each of which is fixed to the magnet frame 212 and attracted to the top of the magnet 213. Each magnetic attracting piece 214 includes an attracting portion 2141, two extension plates 2142 extending upward from both ends of the attracting portion 2141, and two mounting plates 2143 bent outward from the outer side of the extension plates 2142. The magnet frame 212 has three mounting slots 2123. The attracting portion 2141 of each magnetic attracting piece 214 passes through one of the mounting slots 2123 and is attracted to the top of the magnet 213. The two mounting plates 2143 are located on the top surface of the magnet frame 212. In this embodiment, in each magnet attractor 214, the two mounting plates 2143 are located on both sides of a mounting groove 2123. Preferably, the top of the magnet holder 212 and the contact portion of the mounting plate 2143 are recessed downward to form a groove for placing the mounting plate 2143.
[0031] In some embodiments, the braking mechanism 1 further includes a side cover assembly 30, the magnetic braking assembly 20 is disposed on the side cover assembly 30, and the shaft of the reel 10 passes through the magnet assembly 21 and is located within the side cover assembly 30. Specifically, the side cover assembly 30 includes a side cover body 31 and a reel seat 32 connected to the side cover body 31, and the shaft 101 of the reel 10 passes through the magnet assembly 21 and is located within the reel seat 32.
[0032] Understandably, initially, a set distance is maintained between the magnet 213 and the end face 102 of the reel 10. In the initial stage of the casting process, when the reel 10 rotates rapidly, the annular magnet 213, under the influence of an electromagnetic force opposite to the Lorentz force, tends to rotate with the reel 10. When the electromagnetic force on the magnet 213 exceeds the thrust of the elastic element 221, the connecting post 2121 of the magnet frame 212 can move within the groove 2111, causing the entire magnet frame 212 to rotate. Simultaneously, through the engagement of the groove wall of the connecting groove 2122 of the magnet frame 212 and the contour of the corresponding protrusion 2221, the entire magnet frame 212 gradually moves downwards along the edge of the protrusion 2221, thereby causing the magnet 213 attracted to the magnet frame 212 to approach the end face 102 of the reel 10 (e.g., ...). Figure 5As shown, this increases the intensity of the magnetic field lines that the end face 102 of the reel 10 can cut, thereby providing greater braking force to effectively prevent the fishing line from breaking due to the reel 10 rotating too fast. In the later stage of the casting process, as the speed of the reel 10 gradually decreases, the electromagnetic force on the magnet 213 also gradually decreases. When the electromagnetic force decreases to less than the thrust of the elastic element 221, the connecting column 2121 moves in the opposite direction under the action of the elastic force, causing the magnet frame 212 to rotate in the opposite direction. At the same time as the magnet frame 212 rotates in the opposite direction, through the cooperation of the groove wall of the connecting groove 2122 of the magnet frame 212 and the contour of the matching protrusion 2221, the magnet frame 212 moves upward along the edge of the protrusion 2221, thereby causing the magnet 213 to gradually move away from the end face 102 of the reel 10. The intensity of the magnetic field lines that the end face 102 of the reel 10 can cut weakens, thereby reducing the braking force, slowing down the decline of the speed of the reel 10, and increasing the casting distance. It is understood that the braking mechanism 1 of the present invention can automatically and finely adjust the rotation speed of the reel 10 to maintain dynamic balance with the braking force through the magnetic braking component 20, thereby effectively reducing or even avoiding the occurrence of line breakage. In this way, even novice anglers do not have to worry too much about the fishing troubles caused by too many line breakages due to lack of casting skills. For experienced anglers who are skilled in casting techniques, they can handle both swing casting and overcasting, and can enjoy the fun of fishing more confidently and at their own pace.
[0033] Reference Figure 6 , Figure 6 This is a specific embodiment of the baitcasting reel 100 of the present invention. In the embodiment shown in the accompanying drawings, the baitcasting reel 100 includes a fishing reel body 2 and a braking mechanism 1 as described in the above embodiment. The line reel 10 and the magnetic brake assembly 20 in the braking mechanism 1 can be assembled in the fishing reel body 2, and the side cover assembly 30 is connected to the fishing reel body 2.
[0034] Reference Figure 7 and Figure 8 , Figure 7 and Figure 8 The images demonstrate different usage states of the baitcasting reel 100 after the fishing line 3 is wound around it. Initially, as shown... Figure 7 As shown, in the braking mechanism 1 of the present invention, a set distance is maintained between the magnet 213 and the end face 102 of the reel 10. During the initial stage of the throwing process, when the reel 10 rotates rapidly, the annular magnet 213, under the action of an electromagnetic force opposite to the Lorentz force, tends to rotate with the reel 10. When the electromagnetic force on the magnet 213 is greater than the thrust of the elastic element 221, the magnet frame 212 rotates along the contour of the protrusion 2221, resulting in axial displacement, causing the magnet 213 attracted to the magnet frame 212 to approach the end face 102 of the reel 10 (e.g., ...). Figure 8As shown, this increases the strength of the magnetic field lines that the end face 102 of the reel 10 can cut, thereby providing greater braking force. This allows the speed of the reel 10 to be automatically and finely adjusted to maintain dynamic balance with the braking force, thus effectively preventing the fishing line from breaking due to the reel 10 rotating too fast.
[0035] Meanwhile, the present invention can also provide a fishing tackle including the above-mentioned baitcasting reel 100. Except for the baitcasting reel 100, the rest of the structure of the fishing tackle can be the same as the structure of common fishing tackle in the prior art. For example, it can be equipped with a fishing rod, fishing line, etc., the structure of which is well known to those skilled in the art and will not be described in detail here.
[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any way. Those skilled in the art can make various equivalent changes and improvements based on the above embodiments, and all equivalent variations or modifications made within the scope of the claims should fall within the protection scope of the present invention.
