Description

Technical Field

[0001] This application belongs to the field of fishing tackle technology, and relates to electric fishing reel control technology. Specifically, it provides an electric fishing reel control device, an electric fishing reel using the electric fishing reel control device, and a fishing rod equipped with the electric fishing reel. Background Technology

[0002] A fishing reel is an important component of a fishing rod, used for letting out and reeling in fishing line. Because traditional manual fishing reels are time-consuming and laborious to wind the line, electric fishing reels that can achieve various automatic control functions have been increasingly widely used in recent years.

[0003] Existing electric fishing reels generally have a braking function. For example, patent application 201911024776.6 discloses a fishing reel braking adjustment device and a fishing reel braking adjustment program, which has a tension-related information acquisition unit and a braking parameter correction unit, and adjusts the braking parameters of the spool (i.e., the line spool) by detecting the change in fishing line tension during casting. Another example is patent application 202111653421.0, which discloses a spool braking device using eddy currents and a fishing reel equipped with the spool braking device, which can control the rotational speed of the spool by the difference in magnetic force acting on the brake disc of the spool.

[0004] The aforementioned electric fishing reels all utilize the principle of electromagnetic induction. They apply magnetic braking force to the rotating spool through the magnetism of a braking magnet, thus braking the spool. This braking process typically occurs in the latter half of the casting process, when the hook-driven line release speed has decelerated from its highest speed. This is intended to prevent line breakage if the spool speed remains higher than the release speed during this period. However, these electric fishing reels do not optimize the first half of the casting process, i.e., the acceleration of the line-driven spool. At this point, the spool's inertia causes it to drag the line in the opposite direction of casting, resulting in a shorter final casting distance.

[0005] It is evident that optimizing the entire casting process segment by segment to ensure a good match between the spool and the line release status at each stage is a problem that urgently needs to be solved in existing electric fishing reel control technology. Summary of the Invention

[0006] The purpose of this application is to solve the problems existing in the prior art and to provide an electric fishing reel control device, an electric fishing reel using the electric fishing reel control device, and a fishing rod equipped with the electric fishing reel.

[0007] The first aspect of this application provides an electric fishing reel control device for controlling an electric fishing reel. The electric fishing reel has a spool driven by a drive circuit, which is capable of rotating the spool under current drive and generating an induced current through the rotation of the spool. The electric fishing reel control device includes:

[0008] The control unit determines the control mode of the winding drum based on the received judgment signal and outputs a mode selection signal to the mode switching unit. The control mode includes an acceleration mode and a braking mode.

[0009] Mode switching unit: switches the charging and discharging mode of the drive circuit based on the mode selection signal, wherein when the control mode is acceleration mode, the mode switching unit discharges the drive circuit, and when the control mode is braking mode, the mode switching unit charges the drive circuit.

[0010] Furthermore, the judgment signal includes at least one of the following signals: level trigger signal, speed signal, acceleration signal, and attitude signal.

[0011] Furthermore, the winding drum includes a stator and a rotor arranged coaxially, wherein the stator and rotor are respectively provided with mutually cooperating magnetic cores and multiple sets of electromagnetic coils; the drive circuit has a voltage connector, which is electrically connected to each set of electromagnetic coils respectively, and the drive circuit generates a current to drive the rotor based on the voltage at the voltage connector and generates an induced current through the rotation of the rotor.

[0012] Preferably, the judgment signal is the voltage at the voltage connector.

[0013] Specifically, there are three sets of electromagnetic coils; and the driving circuit is a three-phase bridge rectifier circuit.

[0014] Furthermore, the control unit controls the timing and current magnitude of the connection between each group of electromagnetic coils and the drive circuit by outputting multiple speed control signals to the drive circuit.

[0015] Furthermore, the mode switching unit includes: a charging / discharging capacitor and a switching circuit; the first terminal of the charging / discharging capacitor is grounded; the first terminal of the switching circuit is connected to the second terminal of the charging / discharging capacitor, and the second terminal of the switching circuit is connected to the voltage connector of the driving circuit; the control terminal of the switching circuit receives the mode selection signal and controls the current flow direction between the first terminal of the charging / discharging capacitor and the voltage connector based on the mode selection signal and the voltage of the voltage connector.

[0016] Furthermore, the switching circuit includes a transistor, a resistor, a PMOS transistor, and a diode; the base of the transistor receives the mode selection signal, the emitter is grounded, and the collector is connected to the first end of the resistor; the second end of the resistor is connected to the first end of the switching circuit; the gate of the PMOS transistor is connected to the emitter of the transistor Q4, the source is connected to the second end of the charging / discharging capacitor, and the drain is connected to the voltage connector; the anode of the diode is connected to the voltage connector, and the cathode is connected to the second end of the charging / discharging capacitor.

[0017] A second aspect of this application provides an electric fishing reel, including a frame, a spool housed within the frame, a handle for rotating the spool, a drive circuit, and the aforementioned electric fishing reel control device; the drive circuit is capable of rotating the spool under current drive and generating an induced current through the rotation of the spool; the electric fishing reel control device controls the acceleration and braking of the spool based on a received judgment signal.

[0018] A third aspect of this application provides a fishing rod that uses the aforementioned electric fishing reel for letting out and reeling in fishing line.

[0019] The technical solution of this application adds a mode switching unit to the existing electric fishing reel control device. This unit provides additional driving force to the reel through capacitor discharge during the initial line dragging stage of casting, significantly reducing the line drag force required to accelerate the reel. This allows for a faster increase in reel speed to enter the matching stage while minimizing the consumption of the hook's forward kinetic energy, effectively increasing the hook's entry distance into the water. Simultaneously, while braking the reel, it acts as a generator to charge the charging capacitor, effectively converting the energy generated by braking the reel in the later stages of casting into energy to drive the reel in the early stages of the next casting. This eliminates the need for an additional power supply and enables fine-grained control of the entire casting process, greatly extending the matching time between the reel and the fishing line. This prevents line breakage and effectively increases the casting distance. Attached Figure Description

[0027] The present application will now be further described based on preferred embodiments and with reference to the accompanying drawings.

[0029] The terminology used in this specification is for illustrative purposes and is not intended to limit the scope of this application. It should also be noted that, unless otherwise explicitly stated and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this application. Furthermore, for ease of understanding, various components in the drawings have been enlarged or reduced, but this is not intended to limit the scope of protection of this application.

[0030] An electric fishing reel is a type of fishing reel that uses electricity to control the letting out and reeling in of fishing line. Its structure is well known to those skilled in the art. Specifically, an electric fishing reel includes a frame that is fixed relative to the fishing rod, and a spool housed within the frame. The spool is rotatably connected to the frame, and its outer circumference is used to wind fishing line. Generally, an electric fishing reel also includes a handle that allows manual rotation of the spool in either the forward (i.e., letting out) or reverse (i.e., reeling in) direction. This handle is generally rotated at a specific speed ratio by a set of mutually cooperating gears. Furthermore, the gears engage or disengage the handle from the spool through various clutch mechanisms known to those skilled in the art.

[0031] Furthermore, in some embodiments, the electric fishing reel also includes a reciprocating line guiding mechanism. For example, the reciprocating guiding mechanism may include a bidirectional screw and a guide rod arranged parallel to the spool. During the rotation of the spool, the bidirectional screw rotates forward or backward through a gear that meshes with it. The guide member, with a through hole (for the fishing line to pass through), has a thread that meshes with the bidirectional screw and reciprocates along the bidirectional screw under the guidance of the guide rod, thereby achieving uniform winding of the fishing line. The above structure and its operation are well known to those skilled in the art and will not be described in detail here.

[0032] Furthermore, the inside of the winding drum also includes a magnetic core composed of permanent magnets arranged coaxially and a coil combination composed of multiple sets of electromagnetic coils. One of the magnetic cores or coil combinations (e.g., the magnetic core) serves as the stator and remains fixed relative to the frame, while the other (e.g., the coil combination) serves as the rotor and is fixedly connected to the winding drum.

[0033] When the spool rotates relative to the frame, the electromagnetic coil generates an induced current through the magnetic field produced by cutting the magnetic core. At this time, the spool acts as a power generation device, converting rotational kinetic energy into electrical energy, thereby producing a braking effect. In some existing electric fishing reels, as described in the background art, it is possible to determine whether the spool rotation speed has exceeded the casting speed by detecting the tension of the fishing line (e.g., by converting the rotational acceleration of the spool into torque to further obtain tension data), and adjust the braking force on the spool accordingly based on the detection results.

[0034] The purpose of braking the speed of the reel in the above-mentioned prior art is mainly to prevent "line breakage" that occurs when the speed of the reel exceeds the casting speed. Obviously, "line breakage" usually occurs in the latter half of casting. At this time, the speed at which the hook and fishing line move forward has gradually decreased from the highest speed. Until the moment the hook enters the water, its forward speed will drop sharply. During this process, since the moment of inertia of the reel itself is much greater than the momentum of the hook and fishing line, its speed decrease trend is much less than the deceleration of the hook and fishing line. Therefore, it is necessary to effectively brake the reel.

[0035] While using existing control strategies to brake the spool can effectively reduce line breakage, factors affecting the overall casting performance do not only occur in the latter half of the casting process. Figure 1 This demonstrates the entire process of casting a line using a specific existing electric fishing reel, such as... Figure 1 As shown, based on the tension and relative speed relationship between the spool and the fishing line during the casting process, the entire casting process can be divided into the fishing line dragging stage, the matching stage, the spool backlash stage, and the hook entering the water stage.

[0036] During the line dragging phase, the hook needs to generate centrifugal force by swinging the rod. This centrifugal force is converted into a drag force on the spool, causing the spool to gradually accelerate. During this process, the rotation speed of the spool (here, the rotation speed of the spool is the speed of the spool surface) is always the same as the forward speed of the hook until the drag force disappears. At this point, the matching phase begins, where the hook and the spool cast the line at approximately the same speed and remain slack to each other.

[0037] Obviously, during the line dragging stage, if the speed of the reel cannot be increased quickly enough to match the motion of the hook, a large portion of the hook's kinetic energy will be consumed in dragging the reel, resulting in a significant loss of its forward casting energy and greatly shortening the final landing point distance. Therefore, it is necessary to improve the existing control device and strategy of electric fishing reels, and to implement targeted control of the reel based on the interaction between the reel and the fishing line at different stages of the casting process. This would allow for more full utilization of the electromagnetic induction effect between the stator and rotor, effectively increasing the casting distance while preventing line breakage.

[0038] To achieve the above objectives, this application provides an improved electric fishing reel control device for controlling an electric fishing reel. As described above, the electric fishing reel includes at least a frame fixed relative to the fishing rod, and a spool housed within the frame. The spool is rotatably connected to the frame, and its interior includes a permanent magnet (stator) fixed to the frame, and a coil assembly (rotor) consisting of multiple electromagnetic coils fixedly connected to the spool and capable of rotating around the stator.

[0039] Furthermore, the electric fishing reel has a drive circuit for driving the spool, which is capable of rotating the spool under the drive of an electric current and generating an induced current (also known as a resistive circuit) through the rotation of the spool. Figure 2 The diagram shows circuit connection diagrams of the drive circuit in some specific embodiments, such as... Figure 2As shown, the main body of the driving circuit consists of a three-phase bridge rectifier circuit, which is electrically connected to three sets of electromagnetic coils through the U, V, and W terminals respectively. Each rectifier circuit controls the direction of the current by the on / off state of two MOSFETs (in the figure, terminals M1 and M4 are used to control the U circuit, terminals M2 and M4 are used to control the V circuit, and terminals M3 and M6 are used to control the W circuit).

[0040] Furthermore, M1 to M6 are connected to the control unit of the electric fishing reel control device (described later), receiving its output speed control signal. Generally, the speed control signal can be a PWM signal. By adjusting the timing of the PWM signals output to M1 to M6, the electromagnetic coils connected to the U, V, and W circuits can be sequentially switched on and off with the drive circuit according to a certain timing sequence. Simultaneously, by adjusting the duty cycle of the PWM signal, the current magnitude after the electromagnetic coil is switched on can be further adjusted. The above-described technique of controlling the sequential switching of electromagnetic coils via the drive circuit is well known to those skilled in the art and will not be elaborated upon here.

[0041] Furthermore, utilizing the electromagnetic induction effect, the rotor of the winding drum can rotate around the stator under the drive of current in the drive circuit (at this time, the stator-rotor combination is equivalent to an electric motor), and the rotation of the rotor around the stator can generate a corresponding induced current in the drive circuit (at this time, the stator-rotor combination is equivalent to a generator). The state of the stator-rotor is determined by the voltage of the FA terminal (in this application, the FA terminal is also referred to as the voltage connector). When the voltage of the FA terminal is higher than the induced electromotive force generated by the rotor rotation, power is supplied from the FA terminal to the U, V, and W terminals, and the rotor is accelerated by adjusting the rhythm of the PWM signal. Otherwise, the mechanical energy of the rotor rotation is continuously converted into electrical energy and induced current is output from the U, V, and W terminals to the FA terminal, thereby achieving the braking effect on the rotor.

[0042] Figure 2 The drive circuit shown is based on a three-phase bridge rectifier circuit and is only one optional embodiment of this application. It should be understood that when the number of electromagnetic coils in the coil combination is 2, 4 or more, the above drive circuit needs to be adjusted accordingly to meet the control of each electromagnetic coil.

[0043] Figure 3 A schematic diagram of the architecture of an electric fishing reel control device according to some preferred embodiments of this application is shown, such as... Figure 3 As shown, the electric fishing reel control device includes a control unit and a mode switching unit.

[0044] Specifically, such as Figure 3As shown, the control unit is electrically connected to the mode switching unit and is used to output a mode selection signal to the mode switching unit; the mode switching unit switches the charging and discharging mode of the drive circuit based on the received mode selection signal, wherein: when the control mode is acceleration mode, the mode switching unit discharges the drive circuit, and when the control mode is braking mode, the mode switching unit charges the drive circuit.

[0045] The control unit and mode switching unit are described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] In some specific embodiments of this application, the control unit can be implemented using various microprocessor (MCU) chips known to those skilled in the art. Generally, an MCU chip has multiple I / O ports to realize signal input and output. In addition, as those skilled in the art know, the MCU chip can be powered by a built-in button battery or a rechargeable battery.

[0047] Figure 4 A schematic diagram of the implementation principle of the control unit is shown in a specific embodiment, such as... Figure 4 As shown, the core chip of the control unit is specifically model STM32L051X6 / 8. Its output IO ports M1 to M6 are electrically connected to M1 to M6 of the drive circuit, and the on / off state of each electromagnetic coil and the drive circuit is controlled by PWM signal.

[0048] Furthermore, such as Figure 4 As shown, IO01 to IO06 are used to input various judgment signals. The control unit determines whether to charge or discharge the drive circuit based on the received judgment signals through the built-in program, and then outputs the corresponding mode selection signal to the mode switching unit through IO06.

[0049] Transmitting signals of two states through I / O ports is well known to those skilled in the art. For example, in some specific embodiments, the mode selection signal can be a high-level signal or a low-level signal. A high-level signal can be used as the mode selection signal corresponding to the acceleration mode, and a low-level signal can be used as the mode selection signal corresponding to the braking mode. Conversely, a low-level signal can be used as the mode selection signal corresponding to the acceleration mode, and a high-level signal can be used as the mode selection signal corresponding to the braking mode.

[0050] The mode selection signal output by the control unit depends on the evaluation result of the judgment signal. In the embodiments of this application, the type of judgment signal can be various. For example, the rotational speed signal of the spool can be obtained by a counter set in the frame of the electric fishing reel, or the frequency of the on and off of the electromagnetic coils can be detected by a detection circuit connected to each electromagnetic coil, thereby obtaining the rotational speed signal of the spool. Alternatively, by calculating the rate of change of rotational speed, the signal of the rotational acceleration of the spool can be obtained. Obviously, the rotational acceleration can be further converted into the torque of the spool and the corresponding fishing line tension. Another example is that the attitude signal of the electric fishing reel or fishing rod can be obtained by setting an accelerometer at a specific part of the electric fishing reel or fishing rod.

[0051] In addition, the acquisition of judgment signals can also be achieved by combining mechanical structures and circuits. For example, a mode switching button that can automatically pop up and a corresponding circuit can be set on the frame of an electric fishing reel. When the user presses the mode switching button, the circuit is triggered and outputs a high-level signal (or a low-level signal) to the control unit. When the user removes his finger, the mode switching button automatically pops up, and the circuit outputs a low-level signal (or a high-level signal) to the control unit.

[0052] After receiving the aforementioned judgment signals, the control unit assesses the current stage of the fishing line casting using a pre-set evaluation program and outputs the corresponding mode selection signal. For example, when the judgment signal is a level trigger signal, if the control unit receives a level signal triggered by the user pressing the mode switching button, it will output a mode selection signal corresponding to the acceleration mode to the mode switching unit. When the mode switching button is released, the control unit will receive the opposite level signal and output a mode selection signal corresponding to the braking mode to the mode switching unit. Alternatively, the control unit can calculate the tension of the fishing line dragging the reel in real time using continuously received acceleration signals, determine the current stage of the fishing line casting based on the tension, and output the corresponding mode selection signal to the mode switching unit. Furthermore, the control unit can also assess the current stage of the fishing line casting based on the posture signal obtained from the acceleration sensor, and then output the corresponding mode selection signal to the mode switching unit.

[0053] Figure 5 A schematic diagram of the mode switching unit in a preferred embodiment is shown, as follows: Figure 5As shown, the mode switching unit includes a charging / discharging capacitor 100 and a switching circuit 200. The first terminal a1 of the charging / discharging capacitor 100 is grounded, and the second terminal a1 is electrically connected to the first terminal b1 of the switching circuit. The second terminal b2 of the switching circuit is electrically connected to the voltage connector FA of the drive circuit that drives the winding drum. The control terminal c1 of the switching circuit receives the mode selection signal output by the control unit. Based on the mode selection signal, the switching circuit switches between charging and discharging modes. When the mode selection signal is acceleration mode, the switching circuit 200 enters charging mode, and the unidirectional circuit from terminal b1 to terminal b2 is activated, allowing current to flow from terminal a2 of the charging / discharging capacitor 100 to the FA terminal of the drive circuit to drive the winding drum to rotate faster. When the mode selection signal is braking mode, the switching circuit 200 enters discharging mode, and the unidirectional circuit from terminal b2 to terminal b1 is activated, allowing current to flow from the FA terminal of the drive circuit to the a2 terminal of the charging / discharging capacitor 100 to charge the charging / discharging capacitor 200.

[0054] Figure 6 This diagram illustrates the relationship between the spool and the fishing line at each stage of the entire casting process under the control of the aforementioned control device. A comparison is made... Figure 6 and Figure 1 It can be seen that the mode switching unit, composed of the charging / discharging capacitor 100 and the switching circuit 200, can provide additional driving force to the reel through capacitor discharge during the initial line dragging stage of casting. This additional driving force can greatly reduce the dragging force of the fishing line required to accelerate the reel, thereby increasing the speed of the reel to enter the matching stage as quickly as possible while consuming as little forward kinetic energy of the hook. At this time, since most of the kinetic energy of the hook is not consumed in driving the reel, the forward speed of the hook is much higher than that in the case where no additional driving force is provided, i.e., the reel speed is much faster. The speed at which the spool and hook enter the matching state is greatly increased, and the duration of the matching state between the spool and the hook / line is significantly extended, effectively increasing the hook's entry distance into the water. After the hook begins to decelerate, the spool maintains a rotational speed higher than the hook's forward speed. At this point, the drive circuit generates the highest induced electromotive force, and the switching circuit 200 switches to charging mode. While being braked, the spool acts as a generator to charge the charging / discharging capacitor 100. Once the charging / discharging capacitor 100 is fully charged, it can provide driving force to the spool again during the next casting phase. This control mechanism effectively converts the energy generated by the spool's braking in the later stages of casting into energy to drive the spool in the early stages of the next casting. It eliminates the need for an additional power supply and enables detailed control of the entire casting process, significantly extending the matching time between the spool and the line. This effectively increases the casting distance while preventing line breakage.

[0055] Figure 7The circuit schematic of a specific mode switching unit is shown, such as... Figure 7 As shown, the mode switching unit includes capacitor C3-5 (i.e., charging / discharging capacitor 100) and a switching circuit composed of multiple discrete components. Specifically, a unidirectional charging circuit is formed from the FA terminal through diode D7 to the positive terminal of capacitor C3-5, and a unidirectional discharging circuit is formed from the positive terminal of capacitor C3-5 through PMOS transistor to the FA terminal. The source (S) and drain (D) terminals of the PMOS transistor are connected to the positive terminal of C3-5 and the FA terminal, respectively. The mode selection signal is transmitted through IO06 to the base of NPN transistor Q4, whose collector is connected to the gate (G) of the PMOS transistor and then connected to the positive terminal of capacitor C3-5 through a resistor. Its emitter is grounded. The mode selection signal input through IO06 can control the transistor to switch between on and off states, further controlling the high and low levels of the PMOS transistor's gate (G) and switching the unidirectional charging circuit between on and off states. It should be noted that... Figure 7 The embodiments shown are merely illustrative of specific implementations of the mode switching unit switching between charging and discharging modes based on the mode selection signal, and do not constitute a limitation of this application. Those skilled in the art can choose other discrete components or control chips to implement the mode switching unit based on the same technical concept.

[0056] It should be noted that in the embodiments of this application, the switching unit being in acceleration mode or braking mode does not necessarily mean that the switching circuit will discharge from or charge the drive circuit. Its charging and discharging are also affected by the voltage at the positive terminal of the charging and discharging capacitor and the voltage at the FA terminal. For example, when the spool is stationary, even if it is in braking mode, since the electromagnetic coil does not cut the magnetic field to generate an induced current, the FA terminal cannot charge the capacitor C3-5 through diode D7.

[0057] Furthermore, it was found that during the casting and reeling process, the induced electromotive force generated by the rotation of the reel varies between 0V and 10V, and the level of the induced electromotive force is strongly correlated with the rotational speed of the reel. Therefore, in some preferred embodiments, the level of the induced electromotive force can be used to determine the stage of casting and reeling, so as to determine the timing of mode switching.

[0058] Specifically, in some preferred embodiments of this application, the voltage signal at the FA terminal can be used as a judgment signal. During the fishing line dragging stage, the drive circuit drives the reel to accelerate its rotation, causing the voltage at the FA terminal to rise rapidly until it reaches a preset voltage threshold. At this point, the reel's rotation speed is considered sufficient to enter the matching state. The FA terminal voltage can then be continuously monitored, and the braking mode can be switched promptly to prevent the reel from prematurely entering the recoil stage due to continued acceleration. The voltage threshold can be determined by performing multiple casting tests on a specific reel and statistically analyzing the FA terminal voltage value at the point of reaching the matching state. Furthermore, the FA terminal voltage signal can be further combined with the aforementioned rotation speed signal, acceleration signal, etc., to make the judgment of the mode switching timing more accurate.

[0059] Some specific embodiments of this application also provide an electric fishing reel, which includes a frame, a spool housed within the frame, and a handle for rotating the spool. Furthermore, the electric fishing reel includes a drive circuit and the aforementioned electric fishing reel control device. The drive circuit is capable of rotating the spool under current drive and generating an induced current through the rotation of the spool. The electric fishing reel control device controls the acceleration and braking of the spool based on received judgment signals. The specific implementations of the aforementioned drive circuit and electric fishing reel control device have been described in detail above and will not be repeated here.

[0060] Some specific embodiments of this application also provide a fishing rod that uses the aforementioned electric fishing reel for letting out and reeling in fishing line.

[0061] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
