[0005] Patent document 1: Japanese Patent Application Publication No. 2017-189150. Summary of the invention

[0006] In the case of an electric fishing reel, when the fishing line is gradually reeled in by repeatedly shaking the rod while lifting the rod, there is a case where the fishing gear is subjected to a torque greater than necessary due to the resistance of the water, and the winding-up torque greatly exceeds the preset value set by the operating unit. In addition, when the fishing line is reeled in after the shaking rod action, the rotation speed of the reel greatly exceeds the preset value set by the operating unit when the handle is rotated in the reeling direction to continue the reeling operation. In such a case, the motor control device of the electric fishing reel stops the driving of the motor and performs feedback control so that the rotation speed of the reel or the winding-up torque becomes the preset value set by the operating unit, but because the driving of the motor is temporarily stopped, the user may feel a sense of disharmony in the movement of the motor.

[0007] The technical problem to be solved by the present invention is to improve the operability of a fish luring action using an electric fishing reel.

[0008] The motor control device of the electric reel of the first scheme of the present invention is rotatably mounted on the reel body by means of a motor drive. The motor control device includes an operating unit, a speed detection unit, a torque detection unit, and a motor control unit. The operating unit is provided on the reel body. The speed detection unit detects the rotation speed of the reel. The torque detection unit detects the winding torque of the motor. The motor control unit controls the drive output of the motor in multiple stages corresponding to the operation of the operating unit. The motor control unit includes a first output mode and a second output mode. The first output mode is based on the detection result of the speed detection unit. When the first time is more than the first predetermined time, the drive output of the motor is controlled so that the rotation speed of the reel becomes less than the first set speed. The first time is the time when the rotation speed of the reel exceeds the first set speed corresponding to the first predetermined level in the multi-level. The first output mode is based on the detection result of the torque detection unit. When the second time is more than the second predetermined time, the drive output of the motor is limited so that the winding torque of the motor becomes less than the first set torque. The second time is the time when the winding torque of the motor exceeds the first set torque corresponding to the first predetermined level. The second output mode maintains the driving output of the motor when the first time and the second time are respectively less than the first preset time and the second preset time, the first time is the time exceeding the first set speed corresponding to the first preset level, and the second time is the time exceeding the first set torque corresponding to the first preset level.

[0009] In the motor control device of the electric fishing reel, in the second output mode of the motor control unit, when the rotation speed of the reel and the winding torque of the motor exceed the predetermined value for a short time, for example, the drive output of the motor can be maintained. Therefore, when the rod is lifted while the motor is driven to perform a shaking rod action, the drive stop of the motor can be suppressed. As a result, the operability of the fish luring action using the electric fishing reel can be improved.

[0010] In the motor control device for the electric reel according to the first aspect and the second aspect of the present invention, the first predetermined time and the second predetermined time are the same.

[0011] According to the motor control device of the electric reel of the third aspect of the first aspect or the second aspect of the present invention, the duty ratio is fixed in the second output mode to control the drive output of the motor. In this case, the drive output of the motor is stabilized.

[0012] According to the motor control device of the electric reel of the fourth aspect of the first aspect or the second aspect of the present invention, in the second output mode, the duty ratio is changed according to the winding amount to control the drive output of the motor. In this case, in the second output mode, the winding speed can be kept constant.

[0013] In the motor control device of the electric reel of the fifth aspect according to any one of the first to fourth aspects of the present invention, the multi-stage is divided into three areas, namely, a low speed area, a medium speed area where the rotation speed of the motor is faster than the low speed area, and a high speed area where the rotation speed of the motor is faster than the medium speed area, and the second output mode is executed in the low speed area. In this case, for example, the second output mode is executed in the low speed area during the fish luring action, thereby improving the operability of the fish luring action using the electric reel.

[0014] According to the present invention, the operability of the fish luring operation using the electric fishing reel is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 This is a block diagram showing the configuration of a control system of the electric reel.

[0017] Figure 3 This is a flowchart showing an example of the flow of the motor control process of the motor control unit. DETAILED DESCRIPTION

[0018] The electric reel 100 according to one embodiment of the present invention is used. Figure 1 As shown, an electric reel is driven by a motor with the help of electric power supplied from an external power source.

[0019] The electric reel 100 includes a reel body 1, a reel 2, a motor 3, a handle 4, a counter case 5, a first pressing portion 11, a second pressing portion 12, and a motor control portion 17. The first pressing portion 11 and the second pressing portion 12 are examples of an operating portion. The first pressing portion 11, the second pressing portion 12, and the motor control portion 17 constitute a part of a motor control device.

[0020] The reel body 1 includes a frame 6, a first side cover 7 covering one side of the frame 6, a second side cover 8 covering the other side of the frame 6, and a front cover (not shown) covering the front of the frame 6. The reel body 1 includes a horizontal winder mechanism (not shown) that operates in conjunction with the reel 2, a known rotation transmission mechanism (not shown) that transmits the rotation of the motor 3 and the handle 4 to the reel 2, and the like.

[0021] The spool 2 is disposed inside the reel body 1. The spool 2 is rotatably mounted on the reel body 1 between the first side cover 7 and the second side cover 8.

[0022] The motor 3 is disposed inside the reel body 1. The motor 3 is controlled by the motor control unit 17PMW, and rotates and drives the spool 2 in the fishing line winding direction in response to the pressing operation of the first pressing portion 11 and the second pressing portion 12.

[0023] The handle 4 is rotatably supported by the first side cover 7. The rotation of the handle 4 in the line winding direction is transmitted to the spool 2 via a drag mechanism (not shown) and a rotation transmission mechanism that transmits the rotation of the motor 3 to the spool 2.

[0024] The counter case 5 is disposed on the upper portion of the reel body 1. The counter case 5 is fixed to the frame 6. The counter case 5 is provided with a display unit 10 having a liquid crystal display, a first pressing unit 11, a second pressing unit 12, and first to third operating units 13 to 15.

[0025] The first to third operating parts 13 to 15 are mainly used to perform various settings of the electric reel 100. The first to third operating parts 13 to 15 are pressed to operate. The first to third operating parts 13 to 15 may also be a touch panel provided on the display unit 10. A control unit 16 (see FIG. 1 ) that performs various controls is stored inside the counter housing 5. Figure 2 ).

[0026] The first pressing part 11 and the second pressing part 12 are provided on the reel body 1 so as to be pressed and operated. The first pressing part 11 and the second pressing part 12 are seesaw-type pressure-sensitive switches. The first pressing part 11 has a pressure sensor 11a. The pressure sensor 11a outputs a detection value corresponding to the magnitude of the pressing force of the first pressing part 11 as an electrical signal to the motor control part 17. The second pressing part 12 has a pressure sensor 12a. The pressure sensor 12a outputs a detection value corresponding to the magnitude of the pressing force of the second pressing part 12 as an electrical signal to the motor control part 17.

[0027] The control unit 16 is as follows Figure 2 As shown, there are a motor control unit 17 for controlling the motor 3, a wire length measuring unit 18, a speed detection unit 19, and a display control unit 20 for controlling the display unit 10 as functional components. The motor control unit 17 controls the drive output (hereinafter referred to as the motor output) of the motor 3 in response to the pressing operation to the first pressing unit 11 or the pressing operation to the second pressing unit 12 via a motor driving circuit 21 for driving the motor 3 via PWM. The motor driving circuit 21 has a current detection unit 21a for detecting the current flowing in the motor 3. The current detection unit 21a is an example of a torque detection unit for detecting the winding torque of the motor 3. The speed detection unit 19 and the current detection unit 21a constitute a part of the motor control device.

[0028] The control unit 16 is connected to the first pressing unit 11, the second pressing unit 12, and the first to third operating units 13 to 15. In addition, the display unit 10, the reel sensor 22 for detecting the rotation speed and rotation direction of the reel 2, and the storage unit 23 are connected to the control unit 16. The storage unit 23 is, for example, a non-volatile memory, and stores various setting information of the electric reel 100, such as data of winding learning results, data used when calculating the line length, information on the rack position, and information on the ship's side stop position.

[0029] The line length measuring unit 18 measures the line length of the fishing line drawn out from the spool 2 in the same manner as in the related art. The line length measuring unit 18 measures the line length based on data related to the number of rotations of the spool 2. The speed detecting unit 19 detects the rotation speed of the spool 2 using the spool sensor 22.

[0030] The motor control unit 17 controls the motor output in multiple stages corresponding to the pressing operation on the first pressing part 11 and the second pressing part 12. The motor control unit 17 controls the motor output in stages from stopping the output to the maximum output. During the period when the first pressing part 11 is pressed, the motor control unit 17 increases the motor output (for example, the rotation speed of the motor 3) corresponding to the pressing force. During the period when the second pressing part 12 is pressed, the motor control unit 17 reduces the motor output (for example, the rotation speed of the motor 3) corresponding to the pressing force. In addition, the motor output is maintained when the pressing operation on the first pressing part 11 or the second pressing part 12 is stopped. The motor control unit 17 controls the motor 3 in a PWM manner, and the maximum output is a duty cycle of 100%. The motor output is, for example, the rotation speed of the motor 3 and / or the winding torque of the motor 3.

[0031] In the present embodiment, the motor output is adjusted in stages in multiple levels (Nmax+1 level) from 0 to Nmax. Level 0 is the stopped state of the motor 3, and level Nmax is the state where the motor 3 is driven at the maximum output. The motor output is adjusted in 31 levels, for example. For each level of the multiple levels, a set speed and a set torque set corresponding to each level are set, and data related to the set speed and the set torque are stored in the storage unit 23. In the present embodiment, the set speed corresponding to each level is equivalent to the upper limit speed corresponding to each level, and the set torque corresponding to each level is equivalent to the upper limit torque corresponding to each level.

[0032] The motor control unit 17 includes a first output mode and a second output mode. The first output mode controls the motor output so that the rotation speed of the reel 2 becomes less than the first set speed when the first time is longer than the first predetermined time based on the detection result of the speed detection unit 19. The first time is the time when the rotation speed of the reel 2 exceeds the first set speed corresponding to the first predetermined level among the multiple levels. The first output mode limits the motor output so that the hoisting torque of the motor 3 becomes less than the first set torque when the second time is longer than the second predetermined time based on the detection result of the current detection unit 21a. The second time is the time when the hoisting torque of the motor 3 exceeds the first set torque corresponding to the first predetermined level.

[0033] The second output mode maintains the motor output when the first time and the second time are respectively less than the first preset time and the second preset time, wherein the first time is the time exceeding the first set speed corresponding to the first preset level, and the second time is the time exceeding the first set torque corresponding to the first preset level.

[0034] The multi-stage is divided into three regions: a low-speed region, a medium-speed region where the rotation speed of the motor 3 is faster than the low-speed region, and a high-speed region where the rotation speed of the motor 3 is faster than the medium-speed region. The first output mode and the second output mode are executed in the low-speed region. For example, the low-speed region is a region from level 0 to level 9, the medium-speed region is a region from level 10 to level 20, and the high-speed region is a region from level 21 to level 31. That is, the first output mode and the second output mode are executed in the region where the motor output level is from level 0 to level 9, and are not executed in the medium-speed region and the high-speed region. In addition, the motor output level corresponding to each speed region can also be changed.

[0035] For example, in the medium speed domain and the high speed domain, feedback control can be performed in the same manner as before so that the rotation speed or the winding torque of the reel 2 driven by the motor 3 becomes a set speed or a set torque corresponding to a predetermined level set in accordance with the operation of the first pressing part 11 and the second pressing part 12, or the winding diameter of the reel 2 is calculated so that the tension is maintained at a predetermined value. For example, in the medium speed domain and the high speed domain, when the rotation speed of the reel 2 decreases due to the application of a load, feedback control can be performed so as to maintain the predetermined rotation speed. In addition, the first output mode and the second output mode can also be executed in the medium speed domain, or in the medium speed domain and the high speed domain.

[0036] Next, when the power of the electric reel 100 is turned on, Figure 3 The flowchart shown in exemplifies a part of the flow of the motor control process performed by the motor control unit 17 of the control unit 16 .

[0037] In step S11 , the motor control unit 17 reads the current motor output level N.

[0038] In step S12, the motor control unit 17 determines whether the current motor output level N is lower than level 9 (level 9). That is, in step S12, the motor control unit 17 determines whether the current motor output level N is in the low speed range.

[0039] When the motor control unit 17 determines that the current motor output level N is 9 or less, it executes the process of step S13.

[0040] In step S13, the motor control unit 17 determines whether the first time T11 is longer than the first predetermined time T01 based on the detection result of the speed detection unit 19. The first time T11 is the time when the current rotation speed RS11 of the reel 2 exceeds the first set speed RS01 corresponding to the current motor output level N. When the motor control unit 17 determines that the first time T11 is longer than the first predetermined time T01, the processing of step S14 is performed. For example, the first time T11 is measured by a timer not shown. The first predetermined time T01 is, for example, 1 second.

[0041] In step S14, the motor control unit 17 determines whether the second time T21 is longer than the second predetermined time T02 based on the detection result of the current detection unit 21a. The second time T21 is the time when the current hoisting torque TR11 of the motor 3 exceeds the first set torque TR01 corresponding to the current motor output level N. When the motor control unit 17 determines that the second time T21 is longer than the second predetermined time T02, the processing of step S15 is performed. For example, the second time T21 is measured by a timer. The second predetermined time T02 is, for example, 1 second, which is the same as the first predetermined time T01.

[0042] In step S15 , the motor control unit 17 limits the motor output so that the rotation speed RS11 of the spool 2 becomes equal to or less than the first set speed RS01 and the winding torque TR11 of the motor 3 becomes equal to or less than the first set torque TR01 .

[0043] When the motor control unit 17 determines in step S14 that the second time T21 is less than the second predetermined time T02, the motor control unit 17 executes the process of step S16. In step S16, the motor control unit 17 limits the motor output so that the rotation speed RS11 of the reel 2 becomes less than the first set speed RS01.

[0044] When the motor control unit 17 determines in step S13 that the first time T11 is less than the first predetermined time T01, the motor control unit 17 executes the process of step S17. Step S17 is the same process as step S14, and thus the description thereof is omitted.

[0045] In step S17, when the motor control unit 17 determines that the second time T21 is greater than the second predetermined time T02, the motor control unit 17 executes the process of step S18. In step S18, the motor control unit 17 limits the motor output so that the hoisting torque TR11 of the motor 3 becomes less than the first set torque TR01. That is, in steps S15, S16, and S18, the motor output is controlled by the first output mode.

[0046] In step S17, when the motor control unit 17 determines that the second time T21 is less than the second predetermined time T02, the motor control unit 17 performs the processing of step S19. In step S19, the motor control unit 17 maintains the motor output. In step S19, the motor output is controlled by the second output mode. In step S19, the motor control unit 17 controls the motor output by fixing the duty ratio. For example, the motor control unit 17 controls the motor output by fixing the duty ratio corresponding to the first set speed RS01. Thus, the drive of the motor 3 is maintained.

[0047] In addition, in step S19, the motor control unit 17 may change the duty ratio in accordance with the winding amount to control the motor output, thereby maintaining the drive of the motor 3. Specifically, the duty ratio corresponding to the winding amount may be preset by using the diameter of the reel 2 used in the winding learning, and the duty ratio may be changed in accordance with the winding amount based on the measurement result of the wire length measuring unit 18.

[0048] In the motor control device of the electric fishing reel 100, in the second output mode of the motor control unit 17, the drive output of the motor 3 can be maintained when the rotation speed of the spool 2 and the winding torque of the motor 3 exceed the predetermined value for a short time, for example. Therefore, even when the rod is shaken by lifting the rod and the line is continuously wound by the handle 4 and at least one of the rotation speed of the spool 2 and the motor 3 exceeds the predetermined value for a short time, the drive stop of the motor 3 can be suppressed. As a result, the operability of the fish luring action using the electric fishing reel 100 can be improved.

[0049] <Other embodiments>

The first predetermined time may be different from the second predetermined time.
