Description

Technical Field

[0001] The present application relates to the technical field of fishing reels, and in particular to a fishing reel that brakes the rotation of a reel using electric power. Background Art

[0002] Fishing reel is one of the necessary fishing tools for fishing with a cast rod. There are many types of fishing reels, such as spinning wheel type and drum type. The drum type fishing reel includes a main body, a transmission assembly, a brake assembly, a clutch assembly, a reel and a rocker arm. Side covers are provided on both sides of the main body. The transmission assembly, the brake assembly and the clutch assembly are installed in the inner cavity between one of the side covers (i.e., the first side cover) and the main body, and a clutch driver for operating the clutch assembly is installed on the first side cover. When it is necessary to release the line, force is applied to the clutch driver to separate the reel shaft from the transmission shaft in the transmission assembly, so that the reel shaft and its reel can rotate freely, so as to achieve the purpose of releasing the line. When the fish is hooked, it is necessary to apply force to the clutch driver in the opposite direction, so that the reel shaft and the transmission shaft are connected in transmission, and then the rocker arm is rotated to rotate the reel shaft and the reel through the transmission assembly, so that the fishing line is wound around the reel, so as to achieve the purpose of reeling. However, before reeling, the clutch driver needs to be pushed and reset, so that the quick reeling cannot be achieved immediately. For this reason, people have designed a fishing reel in which the clutch drive component can be automatically reset by rotating the rocker arm before reeling, such as the structure disclosed in the document of Chinese patent application publication number CN108684621A. This better overcomes the defect that traditional drum fishing reels cannot reel in quickly.

[0003] In the process of releasing the line with a fishing reel, in order to prevent the line from being blown due to the excessively fast rotation speed of the reel, a damping structure is generally installed in the inner cavity formed between the other side cover (i.e., the second side cover) and the main body of the above-mentioned fishing reel. In order to adapt to various fishing conditions, the damping force generated by the damping structure can often be adjusted as needed, and there are currently a variety of ways to adjust the damping force. When the damping force needs to be adjusted, it is necessary to open the second side cover to operate the corresponding parts; or when other parts need to be maintained, it is also necessary to be able to open the second side cover quickly. For this reason, people have designed a "fishing reel with quick-opening side cover" with a Chinese patent authorization announcement number of CN103461291B, which provides people with a drum reel that can quickly open the side cover by pushing the lock button with one hand. However, the above-mentioned corresponding damping structure is mechanically adjusted, the adjustment method is complex, the damping force adjustment error is large, and the response is slow. In addition, due to structural limitations, the main control chip inside cannot be waterproofed. Once it falls into the water or once the side cover is opened, water can easily enter the fishing reel through the damping structure, causing a short circuit in the chip.

[0004] Therefore, there is an urgent need for a fishing reel that has convenient damping adjustment, good waterproof effect, can be used in various application scenarios, and is highly practical. Summary of the invention

[0008] The spool assembly includes a spool, a spool shaft, a coil, a magnetic conductive part, and a control mainboard. The control mainboard is connected to the coil, and the control mainboard is arranged at the top of the main shell and encapsulated in the encapsulation cover. The top of the encapsulation cover is movably connected with a damping wheel, and the bottom of the damping wheel is connected with a magnetic block. The magnetic block is arranged toward the sensing chip of the control mainboard, and the magnetic pole rotation angle of the magnetic block rotates synchronously with the rotation of the damping wheel. The sensing chip feeds back information to the control mainboard by sensing the rotation angles of the two poles of the magnetic block, and the control unit of the control mainboard controls the closure of the coil according to the feedback information.

[0009] Furthermore, the upper cover includes a receiving slot hole, which is arranged at the top of the upper cover, the top of the receiving slot is a semicircular hole, the bottom of the receiving slot is a semicircular slot, the receiving slot is adapted to the damping wheel, and the damping wheel is connected through the inside and outside of the receiving slot hole.

[0010] Furthermore, a connection hole is provided on the top of the packaging cover, and the bottom of the damping dial is movably connected to the connection hole;

[0011] The magnetic block is coaxially connected to the rotation center of the damping dial, and the N and S poles of the magnetic block are both arranged toward the sensing chip and are arranged in parallel with the sensing chip.

[0012] Furthermore, a bearing connecting cylinder is connected to the middle of the packaging cover and is arranged axially and extends inwardly. An axial through hole is arranged in the middle of the bearing connecting cylinder. The top end of the spool shaft is connected to the axial through hole of the bearing connecting cylinder through a bearing.

[0013] Furthermore, a receiving groove for receiving the packaging cover is provided on the top of the main body shell, the packaging cover is connected to the top of the receiving groove, and one end of the wire cup is connected to the bottom of the top of the receiving groove, so that a relatively closed receiving space is formed in the packaging cover.

[0014] Furthermore, the accommodating space of the packaging cover is filled with resin glue, and the resin glue seals the control mainboard and the coil in a waterproof manner.

[0015] Furthermore, the spool assembly also includes a bearing seat, the bottom of the bearing connecting cylinder is connected to the axial through hole in the middle of the bearing seat, and the bearing seat is arranged between the control main board and the coil.

[0016] Furthermore, the coil is sleeved on the outside of the bearing seat and arranged inside the magnetic conductive part, and the magnetic conductive part is fixedly connected to the top inner wall of the wire cup.

[0017] Furthermore, the spool shaft passes through the coil and is connected to the axis of the spool, the output end of the transmission assembly is connected to the spool shaft and transmits a rotational driving force, and as the spool shaft rotates, the spool shaft drives the spool to rotate, and the coil cuts the magnetic lines of force in the rotating magnetic conductive part and generates an induced current.

[0021] The present application uses a sensing chip to identify the rotation angle of the magnetic block under the damping dial and feeds back information to the main control unit of the control motherboard. The main control unit controls the change of the induced current of the control coil by closing the control coil. The induced current flowing through the coil will cause the coil to generate an induced magnetic field. The induced magnetic field interacts with the fixed magnetic field generated by the magnetic conductive part to generate a braking force on the wire cup, thereby realizing the regulation of the damping force. Compared with the mechanical regulation of the damping force in the prior art, the control and regulation resistance of the present application has the advantages of more sensitive response, more precise and delicate regulation of the damping force, and strong practicality.

[0022] The control main board and coil in the present application are arranged in the packaging cover and are waterproofly sealed by resin glue, which has the advantages of good waterproof effect, strong sealing, suitability for various weather conditions and wide application range.

[0023] In the present application, the magnet of the wire cup assembly is inserted deep into and close to the inner wall of the wire cup, thereby reducing the size of the wire cup, thereby reducing the volume occupied by the wire cup assembly in the main body and reducing the additional size of the main body. At the same time, because the magnet is far away from the central axis of the wire cup, the control arm of the brake system on the wire cup is increased, thereby improving the braking efficiency.
