Description

Technical Field

[0001] This application relates to the field of fishing tackle technology, and in particular to a drum-type fishing reel. Background Technology

[0002] Drum reels, with their significant advantages such as large spool capacity and high maximum drag, are widely used in fishing activities that require a large amount of fishing line, such as deep-sea fishing and large fish catching.

[0003] Existing drum-type fishing reels typically consist of components such as a line groove, an anti-rotation rod arm, side plates, reel feet, and a counterweight. Their internal transmission structure generally includes an input shaft supported on the side cover and the main body, gears mounted on the input shaft, and a drive shaft coaxial with the reel shaft. Rotation of the input shaft by the rocker arm drives a series of gears, enabling the reel to take in and release line. However, the connection between the top cover and the reel body often lacks an effective waterproofing structure. Due to this lack, water can easily enter the reel from the top cover, causing short circuits in the reel's ignition and affecting its normal use and lifespan. Furthermore, to improve waterproofing, additional waterproof side covers are required to seal the inside of teardrop-shaped fishing reels, increasing production steps and costs, and even then, the waterproofing effect is often unsatisfactory.

[0004] Therefore, there is an urgent need to improve the existing drum fishing reel structure to enhance its waterproof performance and overall reliability. Utility Model Content

[0005] The purpose of this application is to provide a drum-type fishing reel to solve the problems of unreasonable structural design and lack of waterproof design in the prior art.

[0006] The embodiments of this application can be implemented through the following technical solutions:

[0007] A drum-type fishing reel includes a main body, a spool assembly, a transmission assembly, a brake assembly, and a rocker arm. The spool assembly is disposed inside the main body and connected to the rocker arm through the transmission assembly. The rocker arm is connected to the outer end of the transmission assembly, and the brake assembly is mounted on the input shaft of the transmission assembly.

[0008] The main body includes an upper cover and a main body shell. A brake main body structure and a locking component are provided between the upper cover and the main body shell. The brake main body structure is connected to the upper inner edge of the main body shell and is fixed in position by the locking component.

[0009] The brake main body structure and locking component work together to divide the main body into two relatively independent spaces. The space located in the upper part of the brake main body structure contains the main control board, which is waterproofed and sealed with glue. The space located in the lower part of the brake main body structure contains the spool assembly. The output end of the main control board and the input end of the spool assembly are connected through a through hole in the brake main body structure.

[0010] Furthermore, the brake main body structure includes a main cover plate, a first through hole, a center hole, a first limiting ring, and an upper main body ring. The first limiting ring and the upper main body ring are disposed on the same side of the main cover plate and extend in the same direction. The first limiting ring is disposed on the outer edge of the center hole, such that the outer side of the first limiting ring forms an accommodating space relative to the inner side of the upper main body ring. The first through hole is disposed in the accommodating space along the axial direction of the main cover plate. The main control board is installed in the accommodating space, and the output end of the main control board is connected to the spool assembly through the first through hole.

[0011] Furthermore, the adhesive filled in the accommodating space is resin adhesive, silicone adhesive, or AB adhesive.

[0012] Furthermore, the locking component is a ring-shaped structure, the main cover plate abuts against the inner wall of the main body shell, the locking component is installed on the outside of the upper main ring and cooperates with the upper protruding edge of the main body shell to firmly limit the main cover plate to the upper part of the main body shell.

[0013] Furthermore, the locking member includes at least two first limiting protrusions arranged circumferentially along the locking member. Correspondingly, the inner wall of the upper edge of the main body shell is provided with second limiting protrusions distributed circumferentially thereon. The locking member is installed in the gap between the main body cover and the second limiting protrusions, and is limited by rotating the locking member until the first limiting protrusion is located below the second limiting protrusion.

[0014] Furthermore, the upper edge of the main shell is provided with a first long opening extending circumferentially therein, and the outer wall of the locking member is provided with a positioning protrusion extending radially outward therein. The positioning protrusion is located at the first long opening, and when the locking member rotates to the point where the first limiting protrusion is below the second limiting protrusion, the positioning protrusion abuts against the side wall of the first long opening.

[0015] Furthermore, the spool assembly includes a spool, a spool shaft, a magnetic ring, and multiple sets of coils. The main control board is connected to the coils. The multiple sets of coils are radially and evenly distributed inside the magnetic ring, with the axial centerline of the spool shaft as the center. They rotate relative to the magnetic ring on the same horizontal plane. The magnetic ring is fixedly connected to the top of the spool. The spool shaft passes through the coils and is connected to the axis of the spool. The output end of the transmission component is connected to the spool shaft and transmits rotational driving force.

[0016] Furthermore, the spool shaft is disposed within the first limiting ring through the central hole, and the first limiting ring contains a bearing. The spool shaft is connected to the brake main body structure through the bearing.

[0017] Furthermore, the brake main body structure also includes a second limiting ring and a lower main body platform. The second limiting ring and the lower main body platform are disposed opposite to the upper main body ring and extend toward the same side. The lower main body platform is located in the cavity of the main body shell. The second limiting ring is disposed along the center line of the main body cover and protrudes from the end face of the lower main body platform.

[0018] Furthermore, a damping dial is connected to the top of the upper cover, and a magnetic block is connected to the bottom of the damping dial, with the magnetic block facing the sensing chip of the main control board.

[0020] This application uses a combination of a brake main body structure and a locking component to divide the main body into two relatively independent spaces. The space located in the upper part of the brake main body structure contains the main control board, which is waterproofed and sealed with glue. The space located in the lower part of the brake main body structure contains the spool assembly. The output end of the main control board and the input end of the spool assembly are connected through a through hole in the brake main body structure to transmit control signals. There is no need to add a cover on the top of the main control board for sealing. The structure is simple and has the advantages of good waterproof sealing. Attached Figure Description

[0033] Figure 1 This is a schematic diagram of the overall structure of a drum-type fishing reel according to this application. The drum-type fishing reel includes a main body 10, a spool assembly, a transmission assembly, a brake assembly 20, and a rocker arm 30. The spool assembly is disposed within the main body 10 and is connected to the rocker arm 30 via the transmission assembly. The rocker arm 30 is connected to the outer end of the transmission assembly and is used to drive the input shaft of the transmission assembly to rotate. The brake assembly 20 is mounted on the input shaft of the transmission assembly and is used to adjust the engagement force between the gear of the transmission assembly and the input shaft. The input shaft of the transmission assembly transmits rotational driving force to the spool assembly through a gear-speed transmission method.

[0034] The transmission assembly, brake assembly 20 and rocker arm 30 are existing technologies, and their transmission methods and specific structures will not be further described here.

[0035] Figure 2 This is an exploded structural diagram of a drum-type fishing reel according to this application, as shown below. Figure 2 As shown, the main body 10 includes an upper cover a1 and a main shell a2. A brake main body structure a3 and a locking member a4 are disposed between the upper cover a1 and the main shell a2. The brake main body structure a3 is connected to the upper inner edge of the main shell a2 and is fixedly connected by the locking member a4. The brake main body structure a3 and the locking member a4 cooperate to divide the main body 10 into two relatively independent spaces. The space located above the brake main body structure a3 contains a main control board 6, and the space located below the brake main body structure a3 contains a spool assembly. The output end of the main control board 6 and the input end of the spool assembly are connected through a through hole in the brake main body structure a3, so that the main control board 6 can transmit control signals to the spool assembly.

[0036] Specifically, Figure 3 , Figure 4 This is a schematic diagram of the brake main body structure a3 in this application, as shown below. Figure 3 , Figure 4As shown, the brake main body structure a3 includes a main cover plate a30, a first through hole a31, a center hole a32, a first limiting ring a33, and an upper main body ring a34. The first limiting ring a33 and the upper main body ring a34 are disposed on the same side of the main cover plate a30 and extend in the same direction. The first limiting ring a33 is disposed on the outer edge of the center hole a32, so that the outer side of the first limiting ring a33 forms an accommodating space relative to the inner side of the upper main body ring a34. The first through hole a31 is disposed in the accommodating space along the axial direction of the main cover plate a30. The main control board 6 is installed in the accommodating space, and the output end of the main control board 6 is connected to the spool assembly through the first through hole a31.

[0037] In some preferred embodiments, to further enhance the waterproof sealing of the accommodating space, the accommodating space is filled with adhesive, which is one or more of resin adhesive, silicone adhesive, and AB adhesive. The main control board 6 is waterproofed and sealed by the filled adhesive, which is used for waterproofing treatment.

[0038] In some preferred embodiments, the locking member a4 is an annular structure, the main cover plate a30 abuts against the inner wall of the main body shell a2, the locking member a4 is installed on the outside of the upper main body ring a34 and cooperates with the inner convex upper edge of the main body shell a2, so as to firmly limit the main cover plate a30 in the upper part of the main body shell a2 and prevent the brake main structure a3 from moving in the axial direction.

[0039] Specifically, the locking member a4 includes at least two first limiting protrusions a41 arranged circumferentially along the locking member a4. Correspondingly, the inner wall of the upper edge of the main body shell a2 is provided with second limiting protrusions a21 distributed circumferentially thereon. When the main body cover plate a30 is installed on the upper part of the main body shell a2 and firmly abuts against the inner wall of the main body shell a2, the locking member a4 is installed in the gap between the main body cover plate a30 and the second limiting protrusions a21. When the locking member a4 is rotated until the first limiting protrusions a41 are located below the second limiting protrusions a21, the locking member a4 is axially limited by the upper edge of the main body shell a2.

[0040] In some preferred embodiments, the upper edge of the main shell a2 is provided with a first elongated opening a22 extending circumferentially therein, and the outer wall of the locking member a4 is provided with a positioning protrusion a42 extending radially outward therein. The positioning protrusion a42 is located at the first elongated opening a22, and when the locking member a4 rotates to the point where the first limiting protrusion a41 is below the second limiting protrusion a21, the positioning protrusion a42 abuts against the side wall of the first elongated opening a22. At this time, the locking member a4 cannot be rotated any further, and the axial displacement of the locking member a4 and the brake main body structure a3 can only be achieved by rotating the locking member a4 in the opposite direction.

[0041] In some preferred embodiments, the brake main body structure a3 further includes a second limiting ring a35 and a lower main body platform a36. The second limiting ring a35 and the lower main body platform a36 are disposed opposite to the upper main body ring a34 and extend toward the same side. The lower main body platform a36 is located in the cavity of the main body shell a2. The second limiting ring a35 is disposed along the center line of the main body cover plate a30 and protrudes from the end face of the lower main body platform a36. The second limiting ring a35 makes the brake main body structure a3 fit more tightly with the spool shaft 2 of the spool assembly.

[0042] In some preferred embodiments, the first limiting ring a33 contains a bearing 7, which includes a bearing pad 71 and a bearing seat 72. The spool shaft 2 passes through the central hole a32 and is fixed in position by the bearing pad 71 and the bearing seat 72.

[0043] In some preferred embodiments, the spool assembly includes a spool 1, a spool shaft 2, a magnetic ring 3, and multiple sets of coils 4, such as... Figure 3 As shown, the main control board 6 is connected to the coil 4. Multiple sets of coils 4 are radially and evenly distributed inside the magnetic ring 3, centered on the axial centerline of the spool shaft 2, and rotate relative to the magnetic ring 3 on the same horizontal plane. The magnetic ring 3 is composed of several magnets or steels evenly distributed along its inner circumference. The inner surfaces of two adjacent magnets or steels have opposite polarities. The magnetic ring 3 is fixedly connected to the top of the spool 1. The spool shaft 2 passes through the coil 4 and is connected to the axis of the spool 1. The output end of the transmission component is connected to the spool shaft 2 and transmits rotational driving force. As the spool shaft 2 rotates, it drives the spool 1 to rotate, causing the coil 4 to cut magnetic lines of force and generate an induced current within the rotating magnetic ring 3. The induced current flowing through the coil 4 will cause the coil 4 to generate an induced magnetic field. This induced magnetic field interacts with the fixed magnetic field generated by the magnetic ring 3, thereby generating a braking force on the spool 1 to jointly form a braking system.

[0044] In some preferred embodiments, a damping dial a5 is connected to the top of the upper cover a1, and a magnetic block is connected to the bottom of the damping dial a5. The magnetic block is positioned facing the sensing chip of the main control board 6. When the damping dial a5 is turned, the rotation angle of the magnetic poles of the magnetic block changes accordingly. The sensing chip senses the rotation angle of the two poles of the magnetic block and feeds back information to the main control unit of the main control board 6. The main control unit controls the closure of the coil 4 according to the feedback information, so that the induced current of the coil 4 changes, thereby realizing the regulation of different degrees of damping force.

[0045] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
