Description

Technical Field

[0001] This application relates to the technical field of fishing gear, and particularly to a spool assembly of a fishing reel. Background Art

[0002] Nowadays, amateur life is becoming more and more diverse, and fishing is increasingly popular among people. The spool assembly is an important component of a fishing reel. The main function of the spool is to hold the fishing line. When the spool rotates, casting or retrieving actions are performed on the fishing line.

[0003] Since the fishing line needs to be frequently retrieved and cast during the use of the fishing reel, high requirements are put forward for the structural stability and durability of the spool assembly. In the prior art, in order to provide a fishing reel with stable structure and not easily damaged, people have made various improvements to the spool assembly of the fishing reel for a long time. For example, a Chinese patent document discloses a spool assembly of a fishing reel, application number: 202321669789.0, which includes a spool, a spool shaft, and a brake assembly. The spool shaft positions the brake assembly on the axis of the spool. The brake assembly includes a yoke ring, a magnet, and a coil assembly that are flattened from bottom to top. The magnet is connected to the upper end face of the yoke ring and is arranged in a ring shape along its circumference. The spool shaft passes through the coil assembly and is connected to the axis of the spool. The wire ends of the coil assembly face the magnet. As the spool shaft rotates, the wire ends of the coil assembly rotate relative to the magnet, and an induced current is generated above the magnet by the coil assembly. Although this solution simplifies the structure to a certain extent, improves the stability of the brake system, and reduces the problem of spool assembly imbalance caused by unstable brake system, however, this solution still has at least the following defects: the position of the coil assembly in the brake assembly is not effectively fixed, and there is no corresponding protection measure, so that the coil assembly is very likely to be disordered due to rotational inertia during the rotation of the spool assembly, reducing the service life of the spool assembly to a certain extent.

[0004] Therefore, there is an urgent need for a new type of spool assembly with good structural stability and strong durability. Utility Model Content

[0005] The purpose of this application is to provide a spool assembly of a fishing reel to solve the problem in the prior art that the service life of the spool assembly is reduced due to unreasonable positioning of the coil assembly and unreasonable structure.

[0032] In addition, for ease of understanding, various components in the drawings are enlarged (thickened) or reduced (thinned), but this is not intended to limit the protection scope of the present application.

[0033] The singular forms of the terms also include the plural meanings, and vice versa.

In the detailed description and claims of the present application, their names may be different.

[0035] The terms used in this specification are for the purpose of describing the embodiments of the present application, but are not intended to limit the present application. It should also be noted that unless otherwise clearly defined and limited, if terms such as "set", "connected", "connected to" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be specifically understood.

[0036] Figure 1 is a schematic diagram of the overall structure of a spool assembly of a fishing reel according to the present application, Figure 2 is a schematic diagram of the disassembled state of a spool assembly of a fishing reel according to the present application, as Figure 1 、 Figure 2 shown, a spool assembly of a fishing reel includes a spool 1, a spool shaft 2, a coil assembly 4, a magnetic conduction part, and a core cover 6. The magnetic conduction part is coaxially arranged with the spool 1 and fixedly connected to the outer end of the spool 1. The core cover 6 and the coil assembly 4 are arranged inside the magnetic conduction part. The core cover 6 is sleeved outside the coil assembly 4 and limits it in the axial and radial directions of the coil assembly 4. Each stator end of the coil assembly 4 passes through the side wall of the core cover 6 and faces the inner wall of the magnetic conduction part, so that the core cover 6 can not only be used as a protective cover to effectively wrap and position the coil assembly 4, but also expose the stator end inside the magnetic conduction part.

[0037] Further, the spool shaft 2 passes through the central axis of the coil assembly 4 and is fixedly connected to the spool 1 and the magnetic conduction part. As the spool shaft 2 rotates, the spool 1 and the magnetic conduction part rotate synchronously. The stator end of the coil assembly 4 cuts the magnetic induction lines in the rotating magnet 5 and generates an induced current. The induced current flowing through the coil assembly 4 will cause the coil assembly 4 to generate an induced magnetic field, and this induced magnetic field interacts with the fixed magnetic field generated by the magnet 5, thereby generating a braking force on the spool 1.

[0038] Specifically, the coil assembly 4 includes a coil 41 and a winding wheel 42. The winding wheel 42 includes a plurality of winding rods radially and uniformly distributed with its axial center line as the center. One end of the winding rod facing away from the axial center line of the winding wheel 42 is the stator end. Among them, the number of the winding rods is even. Taking 12 winding rods as an example, the coil assembly 4 is divided into four groups in total. One end of the coil 41 on each winding rod in the same group is connected together, and the second ends of the coil 41 in each group are respectively connected to the control system.

[0039] In some preferred embodiments, the core cover 6 is sleeved outside the winding wheel 42. As Figure 3 shown, the height H of the winding wheel 42 is set within the range of 1 mm - 5 mm, which is used to reduce the cogging torque of the spool assembly. Of course, when the height of the winding wheel 42 is reduced, in order to meet the power of the motor, the outer diameter dimension of the winding wheel 42 can be correspondingly increased, that is, the length dimension of the winding rod is increased to increase the number of turns of the coil 41 wound on each winding rod.

[0040] In some preferred embodiments, the core cover 6 is of a split structure, and the core cover 6 includes an upper core cover 61 and a lower core cover 62, which is used to facilitate disassembly and installation.

[0041] In some preferred embodiments, the side walls of the upper core cover 61 and the lower core cover 62 are respectively provided with corresponding opening grooves. When the upper core cover 61 and the lower core cover 62 are cooperatively connected, a plurality of corresponding opening grooves cooperate to form a slot hole radially penetrating through the core cover 6. As Figure 4 shown, the stator end of the winding wheel 42 is limited within the slot hole, so that the coil assembly 4 can be limited by the core cover 6 and at the same time the stator end of the coil assembly 4 can be exposed within the magnetic conduction part.

[0042] In some preferred embodiments, in order to enhance its adaptability to other components without affecting the positioning function of the core cover 6, the applicant further optimizes the structure of the core cover 6. As Figure 5As shown, since a control main board or a brake main body structure member is usually arranged above the coil assembly 4 for encapsulating it, the top of the upper core cover 61 may not be provided with a top wall, and the upper core cover 61 is of an annular structure.

[0043] In some preferred embodiments, a plurality of first limiting protrusions 611 are arranged on the inner wall of the upper core cover 61 along the circumferential direction and extend towards its central axis. Correspondingly, a plurality of second limiting protrusions 621 may also be arranged on the inner wall of the lower core cover 62 along the circumferential direction and extend towards its central axis. The first limiting protrusions 611 and the second limiting protrusions 621 are adapted to the outer wall of the coil assembly 4, so that the coil assembly 4 does not displace in its radial direction.

[0044] In some preferred embodiments, since a wire cup 1 with a hollow interior is directly arranged below the coil assembly 4 without other sealing structures, a bottom shell 622 is arranged at the bottom of the lower core cover 62, and a through hole axially penetrating through the center of the bottom shell 622 is used for cooperating with the spool 12.

[0045] In some preferred embodiments, a third limiting protrusion 623 that protrudes upward in a stepped shape in a ring shape is arranged in the middle of the bottom shell 622 for cooperating with the central hole of the winding wheel 42 to position the winding wheel 42.

[0046] In some preferred embodiments, the wire cup 1 includes an upper cup seat 11, a spool 12, and a lower cup seat 13 that are coaxially connected in sequence from top to bottom. The spool 12 is of a cylindrical tube structure with a hollow interior. The upper cup seat 11 and the lower cup seat 13 are respectively connected to both ends of the spool 12, and the spool 12 is used for winding fishing line.

[0047] In some preferred embodiments, a transverse inner partition is arranged in the middle of the spool 12, and a shaft hole axially penetrating through the middle of the inner partition is provided. The wire cup shaft 2 is connected to the shaft hole of the spool 12 for driving the wire cup 1 to rotate by rotating the wire cup shaft 2.

[0048] In some preferred embodiments, the wire cup shaft 2 and the spool 12 are of an integral structure to improve the overall strength of its structure.

[0049] In some preferred embodiments, the diameters of the upper cup seat 11 and the lower cup seat 13 are larger than the diameter of the spool 12 for limiting the fishing line at the spool 12.

[0050] In some preferred embodiments, the magnetic conductive part is connected to the upper part of the upper cup seat 11, and is used to arrange the braking system at the outer end of the top of the spool 12 without occupying the space inside the spool cup, so that the braking system has stronger applicability to spool cups of various sizes and depths.

[0051] In some preferred embodiments, the magnet 5 is fixedly connected to the annular inner wall of the magnetic yoke ring 3. As the spool cup 1 rotates, the spool cup 1 drives the magnetic yoke ring 3 to rotate, and then drives the magnet 5 to rotate synchronously.

[0052] In some preferred embodiments, the magnetic conductive part includes a magnetic yoke ring 3 and a magnet 5. Refer to Figure 2 As shown, for the sake of simplifying the description, the magnetic polarities represented by S and N in the figure are the inner side polarities. The magnet 5 is composed of several pieces of magnetic steel or magnets evenly distributed along the inner peripheral wall of the magnetic yoke ring 3. The magnetic steel is surface-mounted and directly embedded on the inner peripheral wall of the magnetic yoke ring 3. The inner side polarities of adjacent magnets or magnetic steel are opposite. The magnetic yoke ring 3 is used for magnetic shielding, restricting the leakage magnetic field from diffusing outwards, and enhancing the magnetic conduction ability inside the magnetic yoke ring 3.

[0053] Correspondingly, a plurality of coil assemblies 4 are arranged inside the spool cup 1. The plurality of braking coil assemblies 4 are evenly distributed radially inside the magnet 5 with the axial center line of the spool shaft 2 as the center, and rotate relatively in cooperation with the magnet 5 on the same horizontal plane to jointly form a braking system.

[0054] In some preferred embodiments, the magnetic conductive part is a motor magnetic ring, and the motor magnetic ring is an annular integral structure with magnets of different polarities alternately arranged inside and a magnetic field resistance ability outside, which has the advantage of simple structure.

[0055] The specific embodiments of the present application have been introduced in detail above. For those skilled in the art of this technology, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also belong to the protection scope of the claims of the present application.
