Description

Technical Field

[0001] The present application relates to a fishing reel, and in particular to an electric control device for a fishing reel for reeling in and releasing a fishing line by rotating a winding drum. Background Art

[0002] When the fishing reel is casting the bait, the bait flies by inertia, and the bait drives the fishing line to pull the reel to rotate and release the line. When the flight state of the bait changes, it is necessary to respond in time to change the reel rotation speed. Figure 2 As shown, the existing spinning reel rotation state is divided into three stages: T1 is the starting stage, the bait drives the fishing line to pull the spinning reel from static acceleration to the highest speed; T2 is the first deceleration stage, after the starting stage is over, the bait enters the normal flight stage, at this time, the bait is gradually decelerated by air resistance and friction, and the fishing line no longer generates traction on the spinning reel. At this time, the tangential speed of the spinning reel releasing the fishing line by inertia rotation may be greater than the line delivery speed, and the spinning reel needs to be decelerated as appropriate; T3 is the second deceleration stage, the bait stops flying after falling into the water or hitting obstacles such as bridge piers and branches, and the spinning reel continues to rotate by inertia until it stops, and it needs to be decelerated as soon as possible.

[0003] The rotational inertia of the reel will delay the response of the above-mentioned speed change. For example: in the starting stage T1, the kinetic energy of the bait will be consumed during the acceleration of the reel, thereby limiting the flight distance of the bait, especially when the bait is light in weight and its own kinetic energy is low and cannot drive the reel to accelerate to a sufficient speed; in the first deceleration stage T2, the tangential speed of the fishing line released by the inertial rotation of the reel may be greater than the line output speed, resulting in a tangled fishing line; in the second deceleration stage T3, the reel cannot stop in time due to the kinetic energy stored, which leads to a tangled fishing line.

[0004] The existing solution is to reduce the moment of inertia of the reel as much as possible, but excessive reduction of the structural mass of the reel will reduce its own structural strength, so the method of reducing the moment of inertia of the reel is limited. In addition, some fishing reels are equipped with electromagnetic brake devices, which form electromagnetic resistance through the induced current generated by electromagnetic induction, thereby braking the reel (see Patent Documents 1 and 2).

[0005] Patent document 1: application publication number CN110432236A; Patent document 2: application publication number CN115005170A.

[0006] The inventor found that: first, the existing solutions cannot achieve active assistance to accelerate the reel in the starting stage T1; second, in the deceleration stage, the induced current in the existing technology is passively generated by the rotation of the reel. As the reel speed decreases, the electromagnetic resistance rapidly weakens, so it is impossible to respond accurately and quickly, and it is impossible to fundamentally solve the problem of timely deceleration. Especially in the second deceleration stage T3, manual braking generally relies on the operator's subjective perception, which is prone to untimely response, especially when fishing at night and unable to observe the flight status of the bait, it is easier to make mistakes. Summary of the invention

[0007] The present application is completed in view of the above problems, and solves the above problems through the following technical solutions.

[0008] The fishing reel electronic control device of the embodiment of the present application includes a reel for reeling and releasing the fishing line in a rotating manner, a stator winding, a rotor and a controller, wherein: the stator winding is arranged on the fishing reel body, the rotor rotates together with the reel, and the stator winding and the rotor are arranged opposite to each other to form a rotating motor; the controller is arranged on the fishing reel body, the controller includes a processor and a current control unit, the current control unit is electrically connected to the stator winding, and when the speed of the reel needs to be changed, the controller applies a driving current to the stator winding through the current control unit, and the stator winding generates an electromagnetic torque on the rotor.

[0013] Optionally, in an embodiment, the application of the forward current is stopped after the forward current state continues for a first preset time length; or, the application of the forward current is stopped when the speed difference is greater than a second threshold value.

[0014] Optionally, in an embodiment, during the second deceleration stage, a reverse current is applied to the stator winding until the second deceleration stage ends.

[0015] Optionally, in an embodiment, the second deceleration phase begins when the speed difference is greater than a third threshold, or the outlet line speed is lower than a fourth threshold; the second deceleration phase ends when the winding drum rotation speed is lower than a fifth threshold, or the second deceleration phase begins and lasts for a second preset time length.

[0017] Optionally, in an embodiment, a correction signal for correcting the winding drum rotation speed is calculated based on the tangential speed and the outlet speed, and the correction signal controls the reversal current by adjusting the duty cycle of the PWM signal or by varying the strength of the signal.

[0018] Compared with the prior art, the beneficial effects of the present application are: by actively applying a driving current to the stator winding, the rotational inertia of the winding drum is overcome to change the rotational state. In the starting stage T1, a forward current can be applied to provide the auxiliary torque required for the winding drum to accelerate; in the first deceleration stage T2 and / or the second deceleration stage T3, a reverse current can be applied to provide a reverse torque to decelerate the winding drum. Since the applied driving current is not limited by the winding drum rotation speed, the braking response speed can be improved and the control range of the winding drum rotation state can be increased.

[0034] The line guide ring involved in the present application specifically refers to a fishing reel line outlet component or a combination of components, through which the output fishing line passes and is led out to the outside of the fishing reel. For example, the "wire gauge" or "line gauge" of a double-bearing fishing reel usually belongs to this type of component.

[0035] The driving current involved in the present application specifically refers to the current applied to the stator winding by the controller using the electric energy of the energy storage device to apply torque to the winding drum; the rotating motor involved in the present application specifically refers to a device in which the stator winding and the rotor are matched with each other with a certain gap and can rotate relative to each other, converting electrical energy into mechanical energy or converting mechanical energy into electrical energy; the rotor involved in the present application specifically refers to the rotating body part of the rotating motor that is subjected to electromagnetic force and transmits torque to the winding drum; the eddy current involved in the present application specifically refers to the induced current flowing along a closed loop in a conductor.

[0038] like Figure 1 As shown, some prior art fishing reels usually have a structural form, and such a structure of the fishing reel is usually also called a double-bearing fishing reel. The fishing reel includes: a fishing reel body 100, a winding drum 200, a clutch switch 300, a line guide ring 400 and a winding handle 500, and the fishing reel has a gear transmission mechanism and a clutch mechanism; when winding the fishing line, the clutch mechanism is engaged, and the winding handle 500 drives the winding drum 200 to rotate through the gear transmission mechanism; when the clutch switch 300 is pressed, the clutch mechanism is disengaged, and the winding drum 200 is separated from the transmission mechanism. At this time, the winding drum 200 can rotate freely, and is in the line-releasing state. The above is some prior art fishing reels usually have a structural form, and such a structure of the fishing reel is usually also called a double-bearing fishing reel. Of course, the present application can also be combined with other types of fishing reels that release the line by rotating the winding drum.

[0039] The line-out speed involved in the present application specifically refers to the speed of the fishing line passing through the line-out guide ring 400 when the fishing line is released; the tangent speed involved in the present application specifically refers to the speed of releasing the fishing line when the reel 200 rotates; the rotation speed V involved in the present application specifically refers to the speed of releasing the fishing line when the reel 200 rotates. r Specifically refers to the rotation speed of the winding drum 200; the speed difference involved in the present application specifically refers to: the difference between the tangential speed and the outlet speed, that is: speed difference = tangential speed - outlet speed.

[0040] The outlet speed can be detected by the guide ring speed measuring mechanism, which is a line speed sensor, such as Figure 7 As shown, the linear velocity sensor is installed at the outlet to detect the speed information of the fishing line in the outlet guide ring 400, and transmit the detected fishing line speed information to the controller 900. The above-mentioned linear velocity sensor adopts well-known technology, such as commonly used grating sensors, magnetic grating sensors and aberration speed sensors, etc., which can realize the detection of linear speed or displacement. Specifically, the above-mentioned linear velocity sensor can use a photoelectric sensor to detect a fishing line with a sequence of spaced reflective marks; or use a magnetic sensitive sensor to detect a fishing line with a sequence of spaced magnetic signal marks; or use an aberration speed sensor, without limitation. For example, the application publication number CN116439207A discloses a variety of guide ring speed measuring mechanisms.

[0041] The tangent speed can be calculated based on the reel rotation information detected by the rotation detection mechanism. The rotation detection mechanism can be implemented by a photoelectric detection device, a Hall sensor, a proximity switch, a contact switch, etc.; it can also be implemented by an electromagnetic sensor or an inductive sensor, for example, by measuring the change in the induced electromotive force of the coil in the stator winding 801, or by measuring the change in the inductive reactance of the coil in the stator winding 801. Calculating the tangent speed based on the rotation information is a problem of calculating the circumference of a variable diameter reel, which can be implemented by using the predetermined correspondence between the number of turns of the fishing line and the diameter; it can also be implemented by using a fishing line with a signal marker sequence, the signal marker sequence matches the geometric parameters of the reel, so that the interval length of the signal marker sequence increases or decreases in proportion to the increase or decrease in the winding diameter of the fishing line on the reel, and the ratio between the interval length of the signal marker sequence and the corresponding winding diameter meets the preset value, so as to obtain the relative outlet speed and relative tangent speed with the winding diameter as the reference measurement unit. Similarly, the speed difference at this time is the relative speed difference with the winding diameter as the reference measurement unit. In short, measuring tangential velocity is also a well-known technology. For example, application number PCT / CN2023 / 103454 discloses a variety of technologies for measuring tangential velocity.

[0042] It can be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the fishing reel or its braking device. In some embodiments of the present application, the fishing reel or its braking device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently.

[0043] [Example 1]

[0044] like Figure 3 As shown, a fishing reel electric control device according to an embodiment of the present application includes a rotating motor 800 and a controller 900.

[0045] like Figure 4 As shown, the stator winding 801 and the rotor 802 are arranged facing each other to form a rotating motor. The rotor 802 is specifically a magnetic rotor, which is composed of a permanent magnet, and is mounted on the reel shaft 202 via a connecting component 803 so as to be able to rotate integrally with the reel shaft 202; the reel shaft 202 is mounted on the reel 200 so as to be able to rotate integrally with the reel 200; the stator winding is fixedly arranged on the fishing reel body 100 via the circuit board of the controller 900, and can also be arranged on the fishing reel body 100 in other ways.

[0046] The rotating motor of this embodiment is implemented in the form of a brushless motor, and can also be implemented in other well-known motor forms. The rotating motor of this embodiment adopts the structure of a radial flux motor. It should be noted that the stator winding 801 and the magnetic rotor can also be implemented in the structure of an axial flux motor, or in other well-known structures.

[0047] The circuit board of the controller 900 is arranged on the fishing reel body, such as Figure 3 As shown, the controller 900 specifically includes: a processor 901 , a memory, an I / O interface 902 , and a current control unit 903 . The memory includes a RAM memory 904 and a ROM memory 905 .

[0048] The current control unit 903 is a rotating motor drive circuit, electrically connected to the stator winding 801. The controller 900 applies a driving current to the stator winding 801 through the current control unit 903. The driving current forms a rotating magnetic field, which acts on the rotor 802 to generate a rotating torque. In the starting stage T1, the current control unit 903 applies a forward current to the stator winding 801, and / or in the deceleration stage, the current control unit 903 applies a reverse current to the stator winding 801. The deceleration stage is the first deceleration stage T2 and / or the second deceleration stage T3.

[0049] The starting point of the startup phase T1 can be determined in the following way:

[0050] In one method, an acceleration sensor is provided on the fishing reel body, and the acceleration sensor is electrically connected to the controller 900. Since acceleration is generated when casting bait, when the acceleration is detected to be greater than a preset first threshold, it is determined that the start phase T1 begins, triggering the application of a forward current. The first threshold is the acceleration threshold when casting bait, which can be set according to a specific application scenario, or determined through a limited number of tests. As a specific example rather than a limitation: In some embodiments, the first threshold can be 15 m / s 2 In some other embodiments, the first threshold may be 25 m / s 2 In some embodiments, the first threshold may be 50 m / s 2 .

[0051] In another way, a line-releasing state detection device is provided on the fishing reel body. When the line-releasing starts, it is determined that the start-up phase T1 starts, triggering the application of a forward current. The specific line-releasing state detection device can be a clutch state detection device that cooperates with a guide ring speed measurement mechanism or a rotation detection mechanism. When it is detected that the clutch switch 300 is pressed and the fishing line is pulled out or the winding drum rotates, it is determined that the start-up phase T1 starts, triggering the application of a forward current; wherein the clutch state detection device can be implemented by a detection switch electrically connected to the controller 900 and linked to the clutch switch 300, converting the mechanical state position into an electrical signal, and the detection switch can be implemented by an electric contact switch, a proximity switch, a magnetic sensor, a photoelectric sensor, an electromagnetic sensor, etc. The line-releasing state detection device can also be implemented by a rotation detection mechanism with a function of detecting the rotation direction. When it is detected that the winding drum starts to rotate forward, it is determined that the start-up phase T1 starts. The line-releasing state detection device can also be implemented by a guide ring speed measurement mechanism with an aberration speed measurement sensor. When it is detected that the fishing line starts to release the line, it is determined that the start-up phase T1 starts. In short, when the bait is cast, the position, posture and motion state of the mechanical parts of the fishing reel change. These changes can be easily captured by sensors, thereby determining that the start-up phase T1 has begun.

[0052] The end of the startup phase T1 can be determined in the following ways:

[0053] In one embodiment, the time length of the start-up phase T1 is pre-set as a first preset time length, and the forward current is stopped after the forward current state is applied for the first preset time length. The first preset time length can be set according to a specific application scenario, or can be determined by a limited number of tests. For example, in some embodiments, the first preset time length is set within a range of less than 70 milliseconds, in other embodiments, the first preset time length is set within a range of less than 200 milliseconds, and in some other embodiments, the first preset time length is set within a range of less than 500 milliseconds or more.

[0054] In another way, when the speed difference is greater than the second threshold value, it is determined that the start-up phase T1 is over, and the forward current is stopped. In the start-up phase T1, the fishing line is pulled into the reel to rotate, and the speed difference is ≤0, so a second threshold value is set as the basis for judging the end of the start-up phase T1. The second threshold value can be set according to the specific application scenario, and can also be determined through a limited number of tests. As a specific example and not a limitation: in some embodiments, the second threshold value can be 0m / s, in other embodiments, the second threshold value can be 0.003m / s, and in some other embodiments, the second threshold value can be 0.008m / s.

[0055] The starting point of the second deceleration stage T3 can be determined in the following way:

[0056] In one way, when the speed difference is greater than the third threshold, it is determined that the second deceleration stage T3 begins, triggering the application of a reverse current until the second deceleration stage T3 ends. When the second deceleration stage T3 begins, the flying speed of the bait decreases sharply, and the speed difference suddenly increases, so a third threshold is set as a basis for judging the starting point of the second deceleration stage T3. The third threshold can be set according to the specific application scenario, or it can be determined through a limited number of tests. As a specific example rather than a limitation: in some embodiments, the third threshold can be 1m / s, in other embodiments, the third threshold can be 2m / s, and in some other embodiments, the third threshold can be 5m / s.

[0057] In another way, when the outlet speed is lower than the fourth threshold, it is determined that the second deceleration stage T3 begins, triggering the application of a reverse current until the second deceleration stage T3 ends. When the second deceleration stage T3 begins, the flight speed of the bait drops sharply, so a fourth threshold is set as a basis for judging the starting point of the second deceleration stage T3. The fourth threshold can be set according to the specific application scenario, or it can be determined through a limited number of tests. As a specific example and not a limitation: in some embodiments, the fourth threshold can be 0.5m / s, in other embodiments, the fourth threshold can be 1m / s, and in some other embodiments, the fourth threshold can be 2m / s.

[0058] The end of the second deceleration stage T3 can be determined in the following manner:

[0059] In one embodiment, when the winding drum speed is lower than the fifth threshold, it is determined that the second deceleration stage T3 ends. When the second deceleration stage T3 ends, the winding drum speed is very low or stops rotating, so a fifth threshold is set as a basis for judging the end of the second deceleration stage T3. The fifth threshold can be set according to a specific application scenario, or can be determined through a limited number of tests. As a specific example and not a limitation: in some embodiments, the fifth threshold can be 1 rpm, in other embodiments, the fifth threshold can be 2 rpm, and in some other embodiments, the fifth threshold can be 5 rpm.

[0060] In another way, the time length of the second deceleration stage T3 is preset as a second preset time length, and the second preset time length can be set according to a specific application scenario, or can be determined through a limited number of tests. For example, in some embodiments, the second preset time length is set within a range of less than 50 milliseconds, in other embodiments, the second preset time length is set within a range of less than 150 milliseconds, and in some other embodiments, the second preset time length is set within a range of less than 400 milliseconds or more.

[0061] The first deceleration stage T2 is between the end of the starting stage T1 and the start of the second deceleration stage T3. Figure 2 As shown. At this stage, the correction signal for the reel speed correction is calculated according to the tangent speed and the outlet speed, and the reverse current is applied according to the correction signal to control the reel speed to prevent the tangling of the fishing line caused by the tangent speed being greater than the outlet speed. Specifically, closed-loop control can be used. The correction signal is used to adjust the PWM signal duty cycle or to control the reverse current by changing the strength.

[0062] [Example 2]

[0063] like Figure 3 As shown, the device of this embodiment includes a rotating motor 800 and a controller 900 .

[0064] like Figure 5 As shown, the stator winding 801 and the rotor 802 are arranged opposite to each other to form a rotating motor, and the rotor 802 is a plurality of closed coils. In this embodiment, the rotor 802 is specifically a plurality of closed coils formed by hollowing out the side plate of the metal winding drum; the stator winding is fixedly arranged on the fishing reel body 100 via the circuit board of the controller 900, and can also be arranged on the fishing reel body 100 in other ways. The rotating motor of this embodiment adopts the structural form of an axial flux motor. In some embodiments, the structural form of a radial flux motor can also be adopted, or other well-known structural forms can be adopted; in the case of the radial flux motor structural form, the rotor can adopt the hollowing out of the barrel part of the metal winding drum to form a plurality of closed coils; of course, regardless of the motor structural form, according to the common sense of electromagnetics, the rotor can also adopt other forms of closed coils arranged opposite to the stator winding, and the closed coil is assembled with the winding drum to rotate as a whole.

[0065] When a driving current is applied to the stator winding 801, the magnetic field formed by the stator winding causes electromagnetic induction in the closed coil, and the generated Ampere force acts on the rotor 802, thereby generating a rotational torque.

[0066] Compared with the first embodiment, except for the differences described above, other parts are implemented in the same manner as the first embodiment.

[0067] [Example 3]

[0068] like Figure 3 As shown, the device of this embodiment includes a rotating motor 800 and a controller 900 .

[0069] like Figure 6As shown, the stator winding 801 and the rotor 802 are arranged opposite to each other to form a rotating motor. The rotor 802 is specifically formed by the side plate of the metal winding drum; the stator winding is fixedly arranged on the fishing reel body 100 via the circuit board of the controller 900, and can also be arranged on the fishing reel body 100 in other ways. The rotating motor of this embodiment is implemented in the structural form of an axial flux motor. In some embodiments, it can also be implemented in the structural form of a radial flux motor, or in other well-known structural forms; in the case of the radial flux motor structural form, the rotor can be the barrel part of the metal winding drum; of course, no matter what kind of motor structural form, according to the common sense of electromagnetics, the rotor can also be other forms of metal parts arranged opposite to the stator winding, and the metal parts are assembled with the winding drum to rotate as a whole.

[0070] During the deceleration phase, a driving current is applied to the stator winding 801 to generate a magnetic field, and eddy currents are generated in the rotating rotor metal parts. The Ampere force generated by the eddy currents acts on the rotor 802, thereby generating a rotational torque opposite to the rotation direction.

[0071] Compared with the first embodiment, except for the differences described above, other parts are implemented in the same manner as the first embodiment.
