[0003] Patent document 1: Japanese Patent Application Publication No. 2021-016316.

[0004] In such an electric fishing reel, it is desired to improve the operability of the fish luring action by the pressing operation of the pressing portion. Summary of the invention

[0005] An object of the present invention is to improve the operability of a fish luring action of an electric fishing reel.

[0006] The motor control device of the electric reel of the first aspect of the present invention drives a reel rotatably mounted on a reel body by means of a motor. The motor control device includes a pressing portion, a first operating portion, a motor control portion, and an increase degree setting portion. The pressing portion is provided on the reel body in a manner to be pressed and operated. The first operating portion is provided on the reel body. The motor control portion is configured to control the output of the motor in a control mode selected from a plurality of control modes including at least a first control mode. The motor control portion controls the output of the motor in accordance with the pressing force of the pressing portion during the period in which the pressing operation on the pressing portion continues in the first control mode. The increase degree setting portion changes the increase degree of the output of the motor in accordance with the operation of the first operating portion until the output of the motor corresponding to the pressing force in the first control mode is reached.

[0007] In the motor control device of the electric fishing reel, in the first control mode, the increase in the output of the motor can be changed in accordance with the operation of the first operating part until the output of the motor corresponding to the pressing force in the first control mode is reached, thereby improving the operability of the fish luring action based on the pressing operation of the first pressing part.

[0008] The increase degree setting unit of the motor control device of the electric fishing reel according to the second aspect of the first aspect of the present invention is such that, when the first control mode is selected, the increase degree of the motor output corresponding to the pressing force in the first control mode is changed in accordance with the operation of the first operating unit. In this case, for example, when the first control mode is selected, the increase degree of the motor output can be quickly changed until the motor output corresponding to the pressing force is reached, so the operability of the fish luring action is further improved.

[0009] The motor control device of the electric fishing reel according to the third aspect of the first aspect or the second aspect of the present invention further includes an upper limit setting unit that changes the upper limit value of the motor output in the first control mode. In this case, the motor output can be prevented from increasing to a level higher than that envisioned by the angler during the fish luring action based on the pressing operation of the pressing unit.

[0010] The motor control device of the electric reel according to the fourth aspect of the third aspect of the present invention further includes a second operating unit provided on the reel body, and the motor control unit is configured such that, in the first control mode, if the pressing operation to the pressing unit is not performed, the output of the motor is increased to an upper limit value set by the upper limit setting unit in correspondence with the second operating unit being operated. In this case, in the first control mode, the fishing line can be automatically reeled up by the output of the motor corresponding to the upper limit value set by the upper limit setting unit, so the operability of the electric reel in the first control mode is improved.

[0011] The motor control unit of the motor control device of the electric reel according to the fourth aspect of the fifth aspect of the present invention is, in the first control mode, when the output of the motor is maintained at the upper limit value corresponding to the operation of the second operating unit, the output of the motor is stopped corresponding to the second operating unit being operated again. In this case, the operability of the electric reel in the first control mode is further improved.

[0020] The electric winding reel 100 according to one embodiment of the present invention is as follows: Figure 1 1 is an electric winding reel in which a motor is driven by electric power supplied from an external power source.

[0021] The electric reel 100 includes a reel body 1, a spool 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, the second pressing portion 12, and the motor control portion 17 constitute a part of a motor control device.

[0022] 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. A winding mechanism (not shown) that operates in conjunction with the spool 2, a rotation transmission mechanism (not shown) that transmits the rotation of the motor 3 and the handle 4 to the spool 2, and the like are arranged inside the reel body 1.

[0023] 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.

[0024] The motor 3 is disposed inside the reel body 1. The motor 3 is PWM-controlled by the motor control unit 17, and rotationally drives the spool 2 in the winding direction in response to the pressing operation of the first pressing portion 11 and the second pressing portion 12.

[0025] The handle 4 is rotatably supported by the first side cover 7 .

[0026] The counter case 5 is disposed on the upper part 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. The first pressing unit 11 is an example of a pressing unit.

[0027] The first to third operating parts 13 to 15 are mainly used for various settings of the electric reel 100. The first to third operating parts 13 to 15 are operated by pressing. The first to third operating parts 13 to 15 may also be touch panels provided on the display unit 10. The inside of the counter case 5 accommodates a control unit 16 (see Figure 2 ).

[0028] The first pressing portion 11 and the second pressing portion 12 are provided on the reel body 1 in a manner that they can be pressed. The first pressing portion 11 and the second pressing portion 12 are seesaw-type pressure-sensitive switches. The first pressing portion 11 has a pressure sensor 11a. The pressure sensor 11a outputs a detection value corresponding to the magnitude of the pressing force (hereinafter referred to as the first pressing force) of the pressing operation on the first pressing portion 11 as an electrical signal to the motor control portion 17. The second pressing portion 12 has a pressure sensor 12a. The pressure sensor 12a outputs a detection value corresponding to the magnitude of the pressing force (hereinafter referred to as the second pressing force) of the pressing operation on the second pressing portion 12 as an electrical signal to the motor control portion 17.

[0029] The control unit 16 is as follows Figure 2 As shown, the functional structure includes a motor control unit 17 for controlling the motor 3, an increase setting unit 18, an upper limit setting unit 19, and a display control unit 20 for controlling the display unit 10. The motor control unit 17 controls the output of the motor 3 (hereinafter referred to as the motor output) 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 drive circuit 21 for PWM driving the motor 3.

[0030] 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 control unit 16 is connected to 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. The storage unit 23 is, for example, a nonvolatile memory, and stores various setting information of the electric reel 100 such as information on the rack position and information on the boat edge stop position.

[0031] The motor control unit 17 controls the motor output in stages from the stop state to the maximum output. 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. In addition, when a load is applied here and the rotation speed of the reel 2 decreases, feedback control is performed to maintain a predetermined rotation speed.

[0032] In this embodiment, the motor output is adjusted in multiple stages (Nmax+1 stage) from 0 to Nmax. Stage 0 is the stopped state of the motor 3, and stage Nmax is the state where the motor 3 is driven at the maximum output. The motor output is adjusted in 31 stages, for example.

[0033] The motor control unit 17 is configured to control the motor output in any one of a plurality of control modes including at least the first control mode. The motor control unit 17 is configured to control the motor output in a control mode selected from the plurality of control modes. The motor control unit 17 switches the control mode in response to a pressing operation of the third operating unit 15, for example.

[0034] The plurality of control modes include a normal control mode. In the normal control mode, the motor control unit 17 increases the motor output (e.g., the rotation speed of the motor 3) in response to the first pressing force, and decreases the motor output (e.g., the rotation speed of the motor 3) in response to the second pressing force. In the normal control mode, the motor control unit 17 maintains the motor output when the pressing operation on the first pressing unit 11 or the pressing operation on the second pressing unit 12 is released.

[0035] In addition, the lower limit and upper limit of the pressing force output from the pressure sensors 11a and 12a are set (for example, the lower limit is 30 grams and the upper limit is 2 kilograms). And, based on dividing the range of the lower limit and the upper limit into arbitrary levels (for example, 31 equal divisions), the number of level increases and the number of level decreases of the motor output corresponding to each level are set.

[0036] The motor control unit 17 controls the motor output in accordance with the first pressing force while the pressing operation on the first pressing unit 11 continues in the first control mode. The motor control unit 17 reduces the motor output to level 0 in accordance with the release of the pressing operation on the first pressing unit 11 in the first control mode.

[0037] The motor control unit 17 increases the motor output in proportion to the magnitude of the first pressing force in the first control mode. In addition, in the first control mode, the motor output (here, the rotation speed of the motor 3) corresponding to each level is set based on dividing the first pressing force output from the pressure sensor 11a into arbitrary levels (for example, 31 equal divisions) within the range of the lower limit value and the upper limit value.

[0038] like Figure 3 As shown, if the first pressing part 11 is pressed in the first control mode, the motor control part 17 increases the motor output to the motor output level N1 corresponding to the magnitude of the first pressing force in the first control mode. At this time, the motor control part 17 increases the motor output by the increase degree set by the increase degree setting part 18. The increase degree here is, for example, the acceleration (angular acceleration) when the rotation of the motor 3 reaches the rotation speed of the motor 3 corresponding to the motor output level N1 from the stopped state. Figure 3 In FIG. 1 , the horizontal axis represents time and the vertical axis represents the motor output level N.

[0039] The increase degree setting unit 18 changes the increase degree of the motor output until the motor output corresponding to the first pressing force is reached in the first control mode in accordance with the operation of the first operating unit 13. Here, the increase degree setting unit 18 changes the acceleration of the motor 3 until the rotation speed of the motor 3 corresponding to the motor output level N1 is reached in the first control mode in accordance with the operation of the first operating unit 13.

[0040] like Figure 3As shown, the acceleration setting value that can be set by the increase degree setting unit 18 is, for example, three levels of high acceleration H, medium acceleration M, and low acceleration L. The duty ratio corresponding to the high acceleration H is higher than the duty ratio corresponding to the medium acceleration M. The duty ratio corresponding to the medium acceleration M is higher than the duty ratio corresponding to the low acceleration L.

[0041] The set value of the acceleration is stored in the storage unit 23. When the first control mode is selected, the increase degree setting unit 18 changes the acceleration until the rotation speed of the motor 3 corresponding to the motor output level N1 in the first control mode is reached in accordance with the pressing operation on the first operating unit 13.

[0042] Figure 4 1 is a top view of the display unit 10 in the state where the first control mode is selected. The display control unit 20 causes the display unit 10 to display the set value of the acceleration set by the increase degree setting unit 18 when the first control mode is selected. Figure 4 As shown, when the high acceleration H is selected, the display unit 10 displays [H].

[0043] The upper limit setting unit 19 changes the upper limit value of the motor output in the first control mode. Figure 5 As shown, in the first control mode, the maximum value of the motor output is limited to the value set by the upper limit setting unit 19. Here, the motor control unit 17 limits the level of the motor output to the upper limit level NM set by the upper limit setting unit 19. Specifically, in the first control mode, when the first operating unit 13 is pressed with a pressing force greater than the first pressing force corresponding to the upper limit level NM, the motor output is limited to the upper limit level NM. Figure 5 , the horizontal axis represents the first pressing force.

[0044] The control unit 16 switches to the setting mode of the upper limit setting unit 19 in response to, for example, a pressing operation of the third operating unit 15. At this time, the display control unit 20 causes the display unit 10 to display the setting mode of the upper limit level NM. And, for example, the upper limit level NM is selected to an arbitrary level by pressing the first operating unit 13 or the second operating unit 14, and the third operating unit 15 is operated again to change the upper limit level NM.

[0045] The display control unit 20 causes the display unit 10 to display the upper limit value set by the upper limit setting unit 19 when the first control mode is selected. Figure 4 , indicating a state in which the value of the upper limit level NM corresponding to the upper limit value is set to 22.

[0046] like Figure 6As shown, in the first control mode, if there is no pressing operation on the first pressing portion 11, the motor control portion 17 increases the motor output to the upper limit value (here, the upper limit level NM) set by the upper limit setting portion 19 in response to the operation of the second operating portion 14, and maintains the motor output at the upper limit value set by the upper limit setting portion 19. The motor control portion 17 stops the motor output when the fishing line released from the spool 2 reaches the stop line length. The stop line length is set to, for example, a position where the fishing gear attached to the fishing line is easily caught. The motor control portion 17 sets, for example, the line length when the third operating portion 15 is long pressed as the stop line length.

[0047] In the first control mode, when the motor control unit 17 maintains the motor output at the upper limit value (here, the upper limit level NM) in response to the second operating unit 14 being operated, the motor control unit 17 stops the motor output in response to the second operating unit 14 being operated again.

[0048] In the motor control device of the electric fishing reel, in the first control mode, the increase in the motor output can be changed correspondingly with the operation of the first operating part 13 until the motor output corresponding to the first pressing force in the first control mode is reached, thereby improving the operability of the fish luring action based on the pressing operation of the first pressing part 11.

[0049] When the first control mode is selected, the increase degree of the motor output until the motor output corresponding to the first pressing force is reached can be quickly changed by operating the first operating unit 13, so the operability of the fish luring action is further improved.

[0050] Since the motor control device includes the upper limit setting unit 19 , it is possible to prevent the motor output from increasing to a level higher than that expected by the angler during the fish luring operation by the pressing operation of the first pressing unit 11 in the first control mode.

[0051] In the first control mode, the fishing line can be automatically reeled in at the motor output corresponding to the upper limit level NM set by the upper limit setting unit 19 , so the operability of the electric fishing reel in the first control mode is improved.

[0052] <Other embodiments>

[0053] As mentioned above, although one embodiment of the present invention has been described, the present invention is not limited to the above-mentioned embodiment, and various changes can be made within the scope not departing from the gist of the invention.

[0054] The functions of the first pressing portion 11 and the second pressing portion 12 may be interchanged in accordance with the operations of the first to third operating portions 13 to 15 .

[0055] The pressure sensors 11 a and 12 a may not be single components such as pressure-sensitive elements, but may be components that generate outputs in accordance with a minute displacement of a component pressed by a spring having a large elastic coefficient.

[0056] In the above embodiment, the rotation speed of the reel 2 is detected as the motor output for feedback control, but the current value supplied to the motor 3 may be controlled to make the winding torque a predetermined value. Alternatively, the winding wire diameter of the reel 2 may be calculated and the tension may be controlled to a predetermined value.

[0057] The control method for rotating the motor 3 in accordance with the electrical signals output from the pressure sensors 11a and 12a in the above-described embodiment may be arbitrarily selected from two methods: control at a predetermined spool rotation speed or control at a predetermined torque value.

[0058] In the above-mentioned embodiment, when the range of the lower limit value and the upper limit value of the pressing force outputted from the pressure sensors 11a and 12a is divided into arbitrary levels, the range may not be divided equally. The range of the pressing force corresponding to the lower level of the output level of the motor 3 may be made larger than the range of the higher level.

[0059] The motor control process may be performed by recording a program for realizing the motor control process of the motor control unit 17 on a computer-readable recording medium, and executing the program recorded on the recording medium by, for example, a CPU (Central Processing Unit).
