[0001] The present invention relates to a braking device, and more particularly to a braking device for a double-bearing reel for braking a spool rotatably mounted on a reel body, and a fishing reel having the braking device. Background Art

[0002] Conventionally, a double-bearing reel, particularly a baitcasting reel in which a hook assembly such as a bait is mounted on the front end of a fishing line for casting (casting), is provided with a brake device for braking the reel in order to prevent recoil during casting (casting). Among such brake devices, there is a brake device that automatically adjusts the recoil prevention adjustment by rotating a magnet by an electric motor, as disclosed in Patent Document 1.

[0003] In patent document 1, the CPU calculates the rotation speed and rotation acceleration of the reel based on the signal from the sensor for detecting the rotation of the reel and the signal from the timing circuit, and compares the rotation speed and rotation acceleration with the data at regular intervals, thereby causing the non-magnetic conductor to generate eddy current when a difference of a certain value or more is generated, applying a brake to the reel, thereby extending the flight distance of the hook assembly. In addition, in such a braking device, an intermittent gear is axially supported on the reel body in a manner that allows rotational operation, and the intermittent manual gear is meshed with the motor shaft gear or the magnet gear in a manner that can be engaged or disengaged freely, thereby enabling manual adjustment when desired even when the battery generating the motor is exhausted.

[0004] Patent Document 1: Japanese Utility Model Publication No. 4-051581

[0005] However, in the braking device of Patent Document 1, the intermittent manual gear needs to be arranged near the outer casing of the reel in order to enable user operation, and therefore other components cannot be arranged outside the intermittent manual gear, which leads to a problem of increasing the size of the reel. Summary of the invention

[0006] The present invention has been made in view of the above situation, and its object is to provide a braking device for a reel capable of adjusting the braking force by an electric motor, so as to cope with the situation where the battery runs out without increasing the size of the fishing reel. Other objects of the present invention will become clear by referring to the entire specification.

[0007] A braking device for a dual-bearing reel according to one embodiment of the present invention brakes a reel capable of winding a fishing line and which is rotatably mounted on a reel body of the dual-bearing reel, wherein the braking device is constructed to include: a braked portion mounted on the reel; a braking portion that applies braking force to the braked portion; a motor capable of driving a portion of the braking portion; a reduction mechanism that transmits the drive of the motor to a portion of the braking portion; and a power supply that supplies power to the motor, wherein when the energizing torque of the motor is set to T, the holding torque of the motor is set to C, and the maximum torque required to move the braking portion is set to Mmax, the reduction ratio r of the reduction mechanism satisfies Mmax / T<r<Mmax / C.

[0008] The braking device of a dual-bearing reel according to one embodiment of the present invention is configured to further include: a remaining power detection unit, which detects the remaining power of the battery; and a control unit, which controls the motor, and when it is detected that the remaining power of the battery becomes below a specified value, the control unit cuts off the power supply of the braking device after the braking unit becomes a specified state.

[0009] In the braking device of a dual-bearing reel according to one embodiment of the present invention, the braked portion is a conductive member, and the braking portion is a magnetic circuit having at least one rotatable magnet that applies a magnetic force to the conductive member.

[0010] In a braking device of a dual-bearing reel according to one embodiment of the present invention, the braking portion is a magnetic circuit having at least one rotatable magnet which imparts magnetic force to the conductive component, and the prescribed state refers to a state in which the rotatable magnet is moved to a prescribed position.

[0011] In a braking device of a dual-bearing reel according to one embodiment of the present invention, a portion of the braking portion is the rotatable magnet, and the specified position is a position of the rotatable magnet where the magnetic force is the same as the holding force of the motor or the magnetic force is lower than the holding force of the motor.

[0013] A fishing reel according to one embodiment of the present invention is configured to include the braking device of any of the dual-bearing reels described above.

[0014] According to the above embodiment, when the motor is powered off, the braking force is set to a predetermined set value without consuming power by the magnetic force generated in the magnetic circuit, thereby achieving failure protection. In this way, it is possible to provide a braking device that does not require the use of a manual gear with large layout constraints and can cope with the situation where the battery is exhausted without causing the reel to be enlarged, and a fishing reel having the braking device.

DETAILED DESCRIPTION

[0021] Hereinafter, the braking force control device of the present invention and the fishing reel having the braking force control device will be described in detail with reference to the accompanying drawings. In a plurality of drawings, common structural elements are marked with the same reference numerals in the plurality of drawings. It should be noted that, for ease of description, the drawings may not be recorded in exact scale.

[0022] Reference Figures 1 to 4 , a braking device for a dual-bearing reel according to an embodiment of the present invention and a fishing reel having the braking device are described.

[0023] first, Figure 1It is a cross-sectional view of the fishing reel 1, and shows a cross section passing through the central axis of a reduction gear train described later. In order to simplify the description, illustration and description of a part of the known functions of the fishing reel 1 are omitted.

[0024] like Figure 1 As shown, a fishing reel 1 according to an embodiment of the present invention is composed of a frame (reel body) 2, a spool 3, a braked portion (brake unit) 4, a bearing 5, a brake portion (brake unit) 8 including a rotating magnet 6 and a fixed magnet 7, a mounting plate 9, an inner cover 11, a motor 12, a speed reduction unit (speed reduction gear train) 16 including a gear 13, a gear 14, and a gear 15, a magnet gear 17, a battery 18, a control substrate 19, and an outer cover 20. Here, a brake device according to an embodiment of the present invention described later has a braked portion 4 and a brake portion 8 including a rotating magnet 6 and a fixed magnet 7, but may include parts other than these components.

[0025] The frame (reel body) 2 can be mounted on a fishing rod (not shown). The fishing reel 1 has an operating unit (handle) (not shown) similar to conventional fishing reels, and the reel can be wound by rotating the reel in the forward direction through the operation of the user. The rotation of the handle is transmitted to the reel through a transmission unit such as a gear (not shown).

[0026] In addition, the fishing reel 1 has a clutch unit (not shown), and the user can select whether to connect or disconnect the power transmission to the reel by operating the clutch unit. In the connected state, the operating unit can be used to reel in. In the released state, the reel can be freely rotated in the forward and reverse directions, so that the fishing line can be released.

[0027] The fishing reel 1 may also include a dragging unit (not shown) for preventing the breakage of the fishing line by causing the spool to idle when a torque greater than a predetermined value is applied, and a reverse rotation preventing unit (not shown) for preventing the reverse rotation of the handle. Furthermore, an oscillating device (not shown) may be provided for evenly winding the fishing line by reciprocating the position of the guide portion for guiding the fishing line in accordance with the rotation of the spool.

[0028] The reel 3 is supported to be rotatable relative to the reel body 2, and can be rotated in the forward direction to wind the fishing line around the outer circumference. In addition, when casting a bait, the reel 3 rotates in the reverse direction to release the wound fishing line. At this time, if the amount of fishing line released is too much compared to the amount of movement of the bait, etc., the excess line will cause a line entanglement called a backlash, which hinders the normal use of the fishing reel 1. Therefore, an appropriate braking force is applied to the reel 3 by the brake device 10 described later, thereby preventing the backlash.

[0029] The braked part (induction rotor) 4 is coaxially fixed to the reel 3 and cannot rotate, so that a braking torque can be applied to the reel 3. The braked part 4 is made of a conductor such as aluminum, copper, iron, etc., and is formed into a roughly cylindrical shape. In a braking device 10 according to one embodiment of the present invention, a so-called eddy current brake is used to apply a braking force by generating eddy currents in the braked part 4. That is, when a magnetic field is applied to the braked part 4 from the outside, eddy currents are generated in the braked part in motion. Through the interaction between the eddy currents and the magnetic field, a braking torque proportional to the angular velocity of the reel 3 and the strength of the magnetic field is generated.

[0030] in addition, Figure 1 The mounting plate 9 shown can be fixed to the frame 2. By fixing the mounting plate 9 to the frame 2, the reel 3 is axially supported so as to be rotatable. In addition, by using the mounting plate 9 to hold the fixed magnet 7 and the rotating magnet (movable magnet) 6, a braking device 10 described later is formed. In addition, by integrating the mounting plate 9, the middle cover 11 and the outer cover 20, a side plate unit can be formed. In addition, a watertight chamber is formed by the middle cover 11 and the outer cover 20, and electrical components such as substrates, batteries, motors, and sensors can be stored inside.

[0031] Next, the structure of the brake device 10 according to one embodiment of the present invention is described. In the brake device 10 according to one embodiment of the present invention, a magnetic field is applied to the braked part through a magnetic circuit having at least one permanent magnet. In addition, the magnetic circuit is composed of two permanent magnets, and the magnetic field applied to the braked part can be adjusted by moving the permanent magnets relative to each other.

[0032] In addition, if Figure 2 As shown in FIG. 1 , a fixed magnet 7 is arranged on the inner circumference of the braked portion (brake member) 4, and a rotating magnet 6 is arranged on the outer circumference of the braked portion 4. The rotating magnet 6 and the fixed magnet 7 are respectively divided into N equal parts in the circumferential direction (in Figure 2 In the example of the invention, the magnetic field is divided into four equal parts, and the N pole and the S pole are alternately magnetized. Thus, a magnetic field penetrating the braked portion 4 is formed.

[0033] exist Figure 2 In the state (a), the S pole of the fixed magnet 7 faces the N pole of the rotating magnet 6. That is, the opposite poles face each other, and the intensity of the magnetic field penetrating the braked part is the largest. This state is referred to as the maximum braking state. On the other hand, in Figure 2 In the state (b), the S pole of the fixed magnet 7 faces the S pole of the rotating magnet 6, that is, the same poles face each other, and the magnetic field penetrating the braked part is minimum. This state is referred to as the minimum braking state.

[0034] The rotating magnet 6 is capable of rotating and moving between a maximum braking state and a minimum braking state. Specifically, the rotating magnet 6 is fixed to a magnet gear (magnet holding gear) 17 having a gear and made of resin or the like, and the magnet gear 17 is supported by an axis so as to be rotatable within a range of 0° to 90° relative to the mounting plate 9. The magnet gear 17 receives rotation transmission from the motor 12 via a reduction mechanism (reduction gear train) 16. Thus, the rotating magnet 6 can be caused to rotate relative to the fixed magnet 7 by the motor 12. The reduction gear train 16 is a well-known reduction unit, and in one embodiment of the present invention, it is composed of Figure 1 The gear 13, the gear 14, and the gear 15 are shown as three two-stage gears, but the present invention is not limited to this and any configuration is possible. Here, the reduction ratio of the reduction gear train is referred to as r.

[0035] then, Figure 3 The relationship between the position θ of the rotating magnet relative to the fixed magnet and the magnetic potential energy of the magnetic circuit is shown. As shown in the figure, the magnetic potential energy of the magnetic circuit is the highest in the minimum braking state where the same poles face each other, and the lowest in the maximum braking state where the opposite poles face each other. The change is roughly a Sin curve.

[0036] A braking device for a dual-bearing reel according to one embodiment of the present invention brakes a reel capable of winding a fishing line and which is rotatably mounted on a reel body of the dual-bearing reel, wherein the braking device is constructed to include: a braked portion mounted on the reel; a braking portion that applies braking force to the braked portion; a motor capable of driving a portion of the braking portion; a reduction mechanism that transmits the drive of the motor to a portion of the braking portion; and a power supply that supplies power to the motor, wherein when the energizing torque of the motor is set to T, the holding torque of the motor is set to C, and the maximum torque required to move the braking portion is set to Mmax, the reduction ratio r of the reduction mechanism satisfies Mmax / T<r<Mmax / C.

[0037] According to a braking device for a dual-bearing fishing reel according to an embodiment of the present invention, when the motor is powered off, the braking force is made to be a predetermined set value without consuming power by means of the magnetic force generated in the magnetic circuit, thereby achieving failure protection. In this way, it is possible to provide a braking device that does not require the use of a manual gear with large layout constraints, can cope with the situation where the battery is exhausted without causing the fishing reel to be enlarged, and a fishing fishing reel having the braking device.

[0038] Figure 4The relationship between the position θ of the rotating magnet relative to the fixed magnet and the magnitude F(θ) of the magnetic force acting on the rotating magnet is shown. The magnetic force acting on the rotating magnet is obtained by differentiating the magnetic potential energy with respect to the distance, and changes roughly along the Cos curve. In the minimum braking state and the maximum braking state, the magnetic force becomes 0, respectively, and the maximum magnetic force Mmax is reached in the middle. The maximum braking state is a stable point, and a restoring force toward this point is generated even when a slight angle change occurs. The minimum braking state is an unstable point, and a magnetic force toward the stable point is generated when a slight angle change occurs.

[0039] Thus, when the rotating magnet is in the minimum braking state, although no magnetic force is applied to the rotating magnet, when it is subjected to external impact and vibration and is slightly displaced, a magnetic force toward the maximum braking state as a stable point begins to be generated. In addition, when the rotating magnet is between the minimum braking state and the maximum braking state, a magnetic force toward the maximum braking state is generated. Furthermore, when the rotating magnet is in the maximum braking state, no magnetic force is generated. When it is subjected to external impact and vibration and is slightly displaced, a magnetic force is generated to return to the maximum braking state.

[0040] In one embodiment of the present invention, in order to move the rotating magnet by the motor, the moving force of the rotating magnet generated by the motor needs to be greater than the magnetic force generated between the rotating magnet and the fixed magnet. That is, if the energizing torque of the motor is set to T and the reduction ratio between the motor and the rotating magnet is set to r, then r>Mmax / T is required. Thus, in the motor drive, the magnetic force can be overcome and the rotating magnet can be positioned at an arbitrary position.

[0041] On the other hand, when the motor drive stops due to battery exhaustion or power cut of the control board, the motor receives torque in the rotation direction through the gears due to the magnetic force between the rotating magnet and the fixed magnet. When the motor is not powered, cogging torque due to uneven torque acting between the rotor and the stator, and holding torque C due to friction torque of bearings, etc. are usually generated.

[0042] In one embodiment of the present invention, the reduction ratio r is set to r<Mmax / C. Thus, a holding torque of rC is generated between the rotating magnet and the fixed magnet. Figure 4 The torque rC is shown. The points where F(θ)=rC are θ1 and θ2, 0° to θ1° is region A, θ1° to θ2° is region B, and θ2° to 90° is region C.

[0043] Thus, in region B, the maximum magnetic force generated between the rotating magnet and the fixed magnet exceeds the holding torque of the motor, and even when the drive to the motor is interrupted, the fixed magnet can be moved to the maximum braking state without consuming power or requiring special operations.

[0044] In the minimum braking state, the braking torque on the reel is minimized. Therefore, in the case of casting a lure, etc., the possibility of extending the flight distance becomes higher, while on the other hand, the risk of recoil (line entanglement) is the greatest. On the other hand, in the maximum braking state (the state with the highest braking force), the braking torque on the reel is the greatest. Therefore, in the case of casting a lure, etc., although the flight distance is not extended, the risk of recoil (line entanglement) is minimized.

[0045] If the line is entangled to a great extent, the function of the reel will be lost and the user will not be able to continue fishing. Therefore, when the battery supplying power to the motor is exhausted and the motor cannot be driven, it is preferably set to the maximum braking state, thereby enabling the fishing reel to achieve failure protection.

[0046] By means of a braking device 10 of an embodiment of the present invention and a fishing reel having the braking device, the magnetic force generated between the rotating magnet and the fixed magnet can be made greater than the holding torque (holding force) of the motor. Thus, when the power to the motor stops being supplied, it can automatically enter the maximum braking state, and failure protection can be achieved. At this time, since it is not necessary to operate the various gears constituting the reduction mechanism from the outside, there will be no layout constraints, and thus the overall enlargement of the reel can be avoided. In addition, the reduction ratio r is preferably minimized as much as possible on the basis of satisfying r>Mmax / T. Thus, the range of area B can be increased.

[0047] Next, a control method of the brake device 10 according to an embodiment of the present invention is described. As described above, in an embodiment of the present invention, the rotating magnet is rotated relative to the fixed magnet by the motor, thereby adjusting the braking torque to the reel to a predetermined amount. The braking torque corresponding to each condition is set by detecting the rotational movement amount and the rotational speed of the reel as needed.

[0048] A control unit is arranged in the control substrate, and the control unit is composed of electrical components such as a motor driver for passing current to the motor and a microcomputer equipped with a program for determining the driving amount to the motor. The positioning of the motor can be performed by using a known method such as feedforward control using a stepping motor and feedback control using a position sensor. In this way, the rotating magnet can be moved to a specified position, and a specified braking force can be applied to the reel.

[0049] The braking device of a dual-bearing reel according to one embodiment of the present invention is configured to further include: a remaining power detection unit, which detects the remaining power of the battery; and a control unit, which controls the motor, and when it is detected that the remaining power of the battery becomes below a specified value, the control unit cuts off the power supply of the braking device after the braking unit becomes a specified state.

[0050] In the braking device of a dual-bearing reel according to one embodiment of the present invention, the braked portion is a conductive member, and the braking portion is a magnetic circuit having at least one rotatable magnet that applies a magnetic force to the conductive member.

[0051] In a braking device of a dual-bearing reel according to one embodiment of the present invention, the braking portion is a magnetic circuit having at least one rotatable magnet which imparts magnetic force to the conductive component, and the prescribed state refers to a state in which the rotatable magnet is moved to a prescribed position.

[0052] In a braking device of a dual-bearing reel according to one embodiment of the present invention, a portion of the braking portion is the rotatable magnet, and the specified position is a position of the rotatable magnet where the magnetic force is the same as the holding force of the motor or the magnetic force is lower than the holding force of the motor.

[0053] In the braking device for a dual-bearing reel according to one embodiment of the present invention, the speed reduction mechanism is one or more speed reduction gears.

[0054] A fishing reel according to one embodiment of the present invention is configured to include the braking device of any of the dual-bearing reels described above.

[0055] According to a fishing reel having a braking device for a dual-bearing reel according to an embodiment of the present invention, when the motor is powered off, the braking force is set to a predetermined set value by the magnetic force generated in the magnetic circuit without consuming power, thereby achieving failure protection. In this way, it is possible to provide a braking device that does not require the use of a manual gear with large layout constraints, can cope with the situation where the battery is exhausted without causing the reel to be enlarged, and a fishing reel having the braking device.

[0056] In the control unit of the brake device 10 of one embodiment of the present invention, a battery remaining detection unit (battery remaining detection means) for detecting the remaining battery level is provided, and when the remaining battery level becomes less than a predetermined value (for example, 10% of a fully charged state is considered, but not limited to this), the power supply of the brake device can be cut off after the rotating magnet is moved to a predetermined position. This can avoid the risk of a recoil (line entanglement) being kept high when the power is off, and can achieve a fail-safe brake device 10 and a fishing reel having the brake device.

[0057] The remaining amount detection unit for detecting the remaining amount of the battery can cite, for example, a method for detecting the remaining amount of the battery based on the voltage drop of the battery. In this case, a structure for directly reading the potential difference of the battery and a structure for reading the potential difference of a shunt resistor provided in the circuit are considered. In addition, there is a coulomb counting method for measuring the power used from full charge by accumulating the current used, a battery cell modeling method for correcting the coulomb counting method by learning the time change of the battery and the environmental change, and an impedance tracking method for always recording the impedance of the battery, etc., but it is not limited to a specific method.

[0058] The predetermined position to be moved when the remaining battery level is low is preferably Figure 4 Area C shown. In area A, the risk of recoil is high because the braking torque is small. Therefore, when it is in this state before the power is turned off, the power can be turned off after moving to area C. In area B, since the magnetic force exceeds the holding torque of the motor, it cannot maintain its position when the power is turned off, and the movable magnet can automatically move to area C, but since the attraction and holding force between the magnets are roughly balanced, the movable magnet does not move depending on the friction state, etc., and the position of the movable magnet is unstable. Therefore, when it is in this state before the power is turned off, the power can be turned off after moving to area C. In area C, the magnetic force is lower than the holding torque of the motor, so the position of the movable magnet is stable. Moreover, since the braking torque is large, the risk of recoil is low.

[0059] In the control unit of the brake device 10 according to one embodiment of the present invention, when the battery is low, the movable magnet is moved to the area C before the power is turned off. Then, the power of the control device is turned off. Thus, even after the power is turned off, sufficient braking force can be applied to the reel, and although the flight distance of the bait or the like may be reduced, the risk of causing a recoil can be reduced, and a fishing reel with fail-safe can be achieved.

[0060] In this way, when the remaining battery level becomes less than a predetermined value, by cutting off the power supply after the magnetic circuit is in a predetermined state, even in the case of a reduction ratio in area B, a fishing reel with fail-safe protection can be reliably achieved. At this time, since it is not necessary to operate the gears constituting the reduction mechanism from the outside, there are no restrictions on the layout. Therefore, the overall size of the reel can be avoided.

[0061] The size, material and configuration of each structural element described in this specification are not limited to the contents explicitly described in the embodiment, and each structural element can be deformed to have any size, material and configuration that can be included in the scope of the present invention. In addition, the structural elements not explicitly described in this specification can be added to the described embodiment, and part of the structural elements described in each embodiment can be omitted.
