The present invention relates to a motor control device, and more particularly, to a motor control device of an electric reel that drives a spool rotatably mounted on a reel body by a motor.

Japanese Patent Publication No. 2021-16316

In such electric reels, there is a demand for improved operability of the guiding operation by the pressure operation of the pressure section.

The object of the present invention is to improve the operability of the inducing operation in an electric reel.

The motor control device of the electric reel of the first aspect of the present invention drives a spool rotatably mounted on the reel body by a motor. The motor control device has a pressure unit, a first operation unit, a motor control unit, and an increase degree setting unit. The pressure unit is installed on the reel body to be operated by pressure. The first operation unit is installed on the reel body. The motor control unit 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 unit controls the output of the motor according to the pressure force that presses the pressure unit only while the pressure operation to the pressure unit is continued in the first control mode. The increase degree setting unit changes the increase degree of the output of the motor according to the pressure force in the first control mode until the output of the motor is reached according to the pressure force in the first control mode.

In the motor control device of this electric reel, in the first control mode, the increase in the output of the motor until the output of the motor according to the pressing force in the first control mode is reached can be changed according to the operation of the first operating unit, so the operability of the inducing operation by the pressing operation of the first pressing unit can be improved.

The increase setting section of the motor control device of the electric reel of the second aspect according to the first aspect of the present invention changes the increase in the output of the motor until the output of the motor according to the pressing force in the first control mode is reached, in accordance with the operation of the first operating section, when the first control mode is selected. In this case, for example, since the increase in the output of the motor until the output of the motor according to the pressing force is reached can be quickly changed when the first control mode is selected, the operability of the inducing operation is further improved.

The motor control device of the electric reel according to the third aspect according to the first or second aspect of the present invention further comprises an upper limit setting section for changing the upper limit of the output of the motor in the first control mode. In this case, it is possible to prevent the output of the motor from increasing beyond what the angler has assumed during the luring operation by the pressure operation of the pressure section.

The motor control device of the electric reel of the fourth aspect according to the third aspect of the present invention further comprises a second operating unit installed on the reel body, and the motor control unit increases the output of the motor to the upper limit value set by the upper limit setting unit in accordance with the operation of the second operating unit when the pressing operation by the pressing unit is not performed in the first control mode. In this case, since it becomes possible to automatically wind up the fishing line with the output of the motor corresponding to the upper limit value set by the upper limit setting unit in the first control mode, the operability of the electric reel in the first control mode is improved.

The motor control unit of the electric reel motor control device of the fifth aspect according to the fourth aspect of the present invention, when the output of the motor is maintained at the upper limit value in accordance with the operation of the second operation unit in the first control mode, stops the output of the motor in accordance with the operation of the second operation unit again. In this case, the operability of the electric reel in the first control mode is further improved.

According to the present invention, the operability of the inducing operation in an electric reel can be improved.

An electric reel (100) employing one embodiment of the present invention is an electric reel driven by a motor by power supplied from an external power source, as shown in Fig. 1.

An electric reel (100) comprises a reel body (1), a spool (2), a motor (3), a handle (4), a counter case (5), a first pressure unit (11), a second pressure unit (12), and a motor control unit (17). The first pressure unit (11), the second pressure unit (12), and the motor control unit (17) constitute part of a motor control device.

The reel body (1) has 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). Inside the reel body (1), a level wind mechanism (not shown) that operates in conjunction with a spool (2), a rotation transmission mechanism (not shown) that transmits the rotation of the motor (3) and the handle (4) to the spool (2), etc. are arranged.

The spool (2) is arranged 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).

The motor (3) is placed inside the reel body (1). The motor (3) is PWM controlled by the motor control unit (17), and rotates the spool (2) in the line winding direction according to the pressure operation of the first pressure unit (11) and the second pressure unit (12).

The handle (4) is rotatably supported on the first side cover (7).

The counter case (5) is arranged 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 section (10) having a liquid crystal display, a first pressing section (11), a second pressing section (12), and first to third operating sections (13 to 15). The first pressing section (11) is an example of a pressing section.

The first to third operating sections (13 to 15) are mainly used when making various settings of the electric reel (100). The first to third operating sections (13 to 15) are operated by pressure. The first to third operating sections (13 to 15) may be touch panels installed on the display section (10). A control section (16) (see Fig. 2) for performing various controls is accommodated inside the counter case (5).

The first pressure unit (11) and the second pressure unit (12) are installed in the reel body (1) to be pressure-operated. The first pressure unit (11) and the second pressure unit (12) are seesaw-type pressure-reducing switches. The first pressure unit (11) has a pressure sensor (11a). The pressure sensor (11a) outputs a detection value according to the size of the pressure force (hereinafter referred to as the first pressure force) for pressurizing the first pressure unit (11) as an electric signal to the motor control unit (17). The second pressure unit (12) has a pressure sensor (12a). The pressure sensor (12a) outputs a detection value according to the size of the pressure force (hereinafter referred to as the second pressure force) for pressurizing the second pressure unit (12) as an electric signal to the motor control unit (17).

As shown in Fig. 2, the control unit (16) has 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) as a functional configuration. The motor control unit (17) controls the output of the motor (3) (hereinafter referred to as motor output) according to the pressing operation to the first pressing unit (11) or the pressing operation to the second pressing unit (12) through a motor driving circuit (21) that PWM-drives the motor (3).

The control unit (16) is connected to a first pressure unit (11), a second pressure unit (12), and first to third operating units (13 to 15). In addition, the control unit (16) is connected to a display unit (10), a spool sensor (22) for detecting the rotation speed and rotation direction of the spool (2), and a memory unit (23). The memory unit (23) is, for example, a nonvolatile memory, and stores various setting information of the electric reel (100), such as information on the location of the fish habitat layer and information on the boat stop position.

The motor control unit (17) controls the motor output stepwise from a stop state to maximum output. The motor control unit (17) controls the motor (3) in a PWM manner, and the maximum output is a duty ratio of 100%. The motor output is, for example, the rotation speed of the motor (3). In addition, here, when a load is applied and the rotation speed of the spool (2) decreases, feedback control is performed to maintain a predetermined rotation speed.

In this embodiment, the motor output is adjusted in steps from 0 to Nmax (Nmax＋1 step). Step 0 is a state in which the motor (3) is stopped, and the Nmax step is a state in which the motor (3) is driven at maximum output. The motor output is adjusted in, for example, 31 steps.

The motor control unit (17) is configured to control the motor output in 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 according to, for example, a pressure operation of the third operation unit (15).

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)) according to the first pressing force, and decreases the motor output (e.g., the rotation speed of the motor (3)) according to the second pressing force. In the normal control mode, the motor control unit (17) maintains the motor output when the pressing operation to the first pressing unit (11) or the pressing operation to the second pressing unit (12) is released.

In addition, the lower limit and upper limit (e.g., lower limit 30 grams, upper limit 2 kilograms) of the pressure output from the pressure sensor (11a, 12a) are set. Then, after dividing the range of the lower limit and upper limit into arbitrary steps (e.g., 31 equal parts), the number of steps increased and decreased in the motor output corresponding to each step is set.

The motor control unit (17) controls the motor output according to the first pressure force only while the pressure operation to the first pressure unit (11) continues in the first control mode. The motor control unit (17) reduces the motor output to level 0 when the pressure operation to the first pressure unit (11) is released in the first control mode.

The motor control unit (17) increases the motor output in proportion to the size of the first pressure in the first control mode. In addition, in the first control mode, the range of the lower limit and upper limit of the first pressure output from the pressure sensor (11a) is divided into arbitrary steps (e.g., divided into 31 equal parts), and then the motor output (here, the rotation speed of the motor (3)) corresponding to each step is set.

As shown in Fig. 3, when the first pressurizing unit (11) is subjected to a pressurizing operation in the first control mode, the motor control unit (17) increases the motor output to the motor output stage (N1) corresponding to the size of the first pressurizing force in the first control mode. At this time, the motor control unit (17) increases the motor output by the increase set in the increase setting unit (18). The increase here is, for example, the acceleration (angular acceleration) when the rotation speed of the motor (3) corresponding to the motor output stage (N1) is reached from a state in which the rotation of the motor (3) is stopped. In Fig. 3, the horizontal axis represents time, and the vertical axis represents the motor output stage (N).

The increase setting unit (18) changes the increase of the motor output until the motor output according to the first pressure in the first control mode is reached, in accordance with the operation of the first operating unit (13). Here, the increase setting unit (18) changes the acceleration of the motor (3) until the rotation speed of the motor (3) corresponding to the motor output stage (N1) in the first control mode is reached, in accordance with the operation of the first operating unit (13).

As shown in Fig. 3, the setting values of the acceleration that can be set by the increase setting unit (18) are, for example, three stages of high acceleration (H), medium acceleration (M), and low acceleration (L). The duty ratio corresponding to high acceleration (H) is higher than the duty ratio corresponding to medium acceleration (M). The duty ratio corresponding to medium acceleration (M) is higher than the duty ratio corresponding to low acceleration (L).

The acceleration setting value is stored in the memory (23). The increase setting unit (18) changes the acceleration until the rotation speed of the motor (3) corresponding to the motor output stage (N1) in the first control mode is reached in accordance with the pressure operation of the first operating unit (13) when the first control mode is selected.

Fig. 4 is a plan view of the display unit (10) in a state where the first control mode is selected. The display control unit (20) causes the display unit (10) to display the acceleration setting value set by the increase setting unit (18) in a state where the first control mode is selected. As shown in Fig. 4, the display control unit (20) causes the display unit (10) to display [H] when high acceleration (H) is selected.

The upper limit setting unit (19) changes the upper limit value of the motor output in the first control mode. That is, as shown in Fig. 5, the motor control unit (17) limits the maximum value of the motor output to the value set by the upper limit setting unit (19) in the first control mode. Here, the motor control unit (17) limits the stage of the motor output to the upper limit stage (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 stage (NM), the motor output is limited to the upper limit stage (NM). In Fig. 5, the horizontal axis represents the first pressing force.

The control unit (16) switches to the setting mode of the upper limit setting unit (19) according to, for example, the pressure operation of the third operation unit (15). At this time, the display control unit (20) displays the setting mode of the upper limit stage (NM) on the display unit (10). Then, for example, the first operation unit (13) or the second operation unit (14) is pressure-operated to select the upper limit stage (NM) as an arbitrary stage, and the upper limit stage (NM) is changed by operating the third operation unit (15) again.

The display control unit (20) displays the upper limit value set by the upper limit setting unit (19) on the display unit (10) when the first control mode is selected. In addition, Fig. 4 illustrates a state in which the value of the upper limit step (NM) corresponding to the upper limit value is set to 22.

As shown in Fig. 6, in the first control mode, if the pressure operation by the first pressure unit (11) is not performed, the motor control unit (17) increases the motor output to the upper limit value set by the upper limit setting unit (19) (here, the upper limit step (NM)) according to the operation of the second operation unit (14), and maintains the motor output at the upper limit value set by the upper limit setting unit (19). The motor control unit (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 a position where the tackle attached to the fishing line is easy to catch, for example. The motor control unit (17) sets, for example, the line length when the third operation unit (15) is pressed for a long time, as the stop line length.

The motor control unit (17) stops the motor output when the second operating unit (14) is operated again while maintaining the motor output at the upper limit value (here, the upper limit step (NM)) in the first control mode.

In the motor control device of this electric reel, in the first control mode, the increase in the motor output until reaching the motor output according to the first pressing force in the first control mode can be changed according to the operation of the first operating unit (13), so the operability of the inducing operation by the pressing operation of the first pressing unit (11) can be improved.

When the first control mode is selected, the increase in motor output until reaching the motor output according to the first pressure can be quickly changed by operating the first operating unit (13), so the operability of the manipulating operation is further improved.

Since the motor control device is equipped with an upper limit setting section (19), in the first control mode, it can prevent the motor output from increasing beyond what the angler expected during the luring operation by the pressure operation of the first pressure section (11).

In the first control mode, it is possible to automatically wind up the fishing line with the motor output corresponding to the upper limit step (NM) set by the upper limit setting section (19), so the operability of the electric reel in the first control mode is improved.

<Other embodiments>

Above, although one embodiment of the present invention has been described, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.

Depending on the operation of the first to third operating units (13 to 15), the functions of the first pressure unit (11) and the second pressure unit (12) may be interchanged.

The pressure sensor (11a, 12a) may not be a single component such as a pressure reducing element, but may be one that outputs according to the minute displacement amount of a member pressed by a spring with a large spring constant.

In the above embodiment, the rotation speed of the spool (2) was detected as the motor output and feedback controlled, but it is also possible to control the current value supplied to the motor (3) so that the winding torque becomes a predetermined value. Alternatively, it is also possible to calculate the line winding diameter of the spool (2) and control the tension so that it becomes a predetermined value.

In the above embodiment, the control method for rotating the motor (3) according to the electric signal output from the pressure sensor (11a, 12a) may be arbitrarily selected from two methods: controlling at a predetermined spool rotation speed or controlling at a predetermined torque value.

In the above embodiment, when dividing the range of the lower limit and upper limit of the pressure output from the pressure sensor (11a, 12a) into arbitrary steps, the range does not have to be divided equally. The range of the pressure corresponding to a step with a low step increase number and step decrease number of the output step of the motor (3) may be made larger than the range of a high step.

It is also possible to record a program for realizing the motor control processing of the aforementioned motor control unit (17) in a computer-readable recording medium, and have the program recorded in the recording medium be executed by, for example, a CPU (Central Processing Unit).
