Description

Technical Field

[0001] This invention relates to the field of power generation technology, and more specifically, to a single-rope reciprocating transmission type human-powered power generation device and its control method, which is particularly suitable for emergency power supply, outdoor activities and other scenarios. Background Technology

[0002] Human-powered generators, as emergency power sources independent of the power grid, are of significant value in outdoor activities and emergency rescue scenarios. Currently, common human-powered generators mainly include hand-cranked generators and pull-rope generators. Hand-cranked generators typically use a crank-rocker mechanism to drive the generator, requiring continuous circular cranking by the user, which can lead to operator fatigue, and the transmission efficiency is limited by the mechanism. Traditional pull-rope generators often use a single rope directly wound around the generator shaft. Power is generated when pulled out, and recovery relies on springs or gravity. This process generates no power or is extremely inefficient, exhibiting a "dead zone" that results in discontinuous energy capture and overall low efficiency. Furthermore, the power generation load of these devices is usually fixed, unable to adapt to the wide range of variations in the force and rhythm of human input. When the user exerts significant force, excess mechanical energy is wasted because it cannot be fully absorbed; when the force is less, the system operates in an inefficient range.

[0003] Therefore, there is an urgent need for a continuous, efficient, labor-saving, safe, and effective human-powered power generation solution that can eliminate the return dead zone in the mechanical structure and achieve dynamic load adaptation in the control. Summary of the Invention

[0004] The present invention aims to provide a human-powered power generation device and its control method based on single-rope reciprocating transmission, so as to solve the problems of "return dead zone", discontinuous energy capture, inability to adapt to changes in human input and easy operator fatigue in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A single-rope reciprocating transmission type human-powered power generation device includes: Base; A drive shaft mechanism is rotatably mounted on the base, comprising a first drive shaft section and a second drive shaft section arranged sequentially along the axial direction and capable of rotating relatively independently; The first transmission wheel and the second transmission wheel are arranged at an axial interval along the first transmission shaft segment; The first one-way transmission component and the second one-way transmission component have their inner rings fixedly connected to the first transmission shaft segment, and their outer rings fixedly connected to the first transmission wheel and the second transmission wheel, respectively, and their locking directions are configured to be the same. A single pull rope is mounted on the base with a pulley fixing frame and a reversing pulley supported by the pulley fixing frame. Corresponding sections of the pull rope pass through the pulley fixing frame and around the reversing pulley in sequence. The first end of the pull rope is wound around the first drive wheel in a first helical direction, and the second end of the pull rope is wound around the second drive wheel in a helical direction opposite to the first helical direction. The winding method is coordinated with the locking directions of the first and second one-way transmission components, such that when the user pulls the first end of the pull rope, the first transmission wheel drives the first transmission shaft segment to rotate in a preset direction through the first one-way transmission component, while the second transmission wheel idles; when the user pulls the second end of the pull rope, the second transmission wheel drives the first transmission shaft segment to rotate in the same preset direction through the second one-way transmission component, while the first transmission wheel idles. The inertia wheel is coaxially and fixedly connected to the second drive shaft section; The generator has its input shaft connected to the second transmission shaft section via a transmission mechanism; The power management unit is connected to the power output terminal of the generator and is used to rectify, stabilize, and manage the power generated by the generator. The power output interface is electrically connected to the output terminal of the power management unit and is used to output power externally.

[0006] In one embodiment, the first end of the pull rope is connected to the second end of the pull rope to form a loop-shaped pull rope closed loop.

[0007] In one embodiment, a third one-way transmission member is provided between the first transmission shaft segment and the second transmission shaft segment. The inner ring of the third one-way transmission member is fixedly connected to the first transmission shaft segment, and its outer ring is fixedly connected to the second transmission shaft segment through a connector. Its locking direction is the same as that of the first one-way transmission member and the second one-way transmission member.

[0008] In one embodiment, a pull rope anti-detachment cover is further included. The pull rope anti-detachment cover includes a first pull rope anti-detachment cover and a second pull rope anti-detachment cover respectively covering the radially outer side of the first drive wheel and the second drive wheel. Both the first pull rope anti-detachment cover and the second pull rope anti-detachment cover are provided with holes for the pull rope to pass through and exit, and a gap is left between the pull rope anti-detachment cover and the corresponding drive wheel.

[0009] In one embodiment, the power management unit includes: An energy storage unit is used to store the electrical energy generated by the generator; The control unit is used to sample the electrical feedback signal of the generator in real time, calculate the real-time rotational speed and angular acceleration of the inertial wheel based on the electrical feedback signal, and dynamically adjust the equivalent load of the generator based on the angular acceleration. Status indicator lights, connected to the control unit, are used to provide visual guidance based on the system's operating status.

[0010] In one embodiment, the inertial wheel has an integrated structure of a hub, a counterweight rim, and fan-shaped spokes. When the inertial wheel rotates, the fan-shaped spokes drive airflow toward the area where the generator, the energy storage unit, and / or the control unit are located.

[0011] A control method for a single-rope reciprocating transmission type human-powered power generation device includes the following steps: The electrical feedback signal of the generator is sampled in real time; The real-time rotational speed and angular acceleration of the inertial wheel are calculated based on the electrical feedback signal. Based on the comparison between the absolute value of the angular acceleration and a preset threshold, the output current of the generator is dynamically adjusted to adapt to changes in human input.

[0012] In one embodiment, the dynamic adjustment includes: When the angular acceleration is greater than a first set threshold, the output current of the generator is increased to capture the peak mechanical power; When the absolute value of the angular acceleration is less than the second set threshold and the real-time rotational speed is higher than the minimum operating speed, the maximum power point tracking (MPPT) algorithm is executed to fine-tune the output current to find the optimal power generation point. When the angular acceleration is less than zero, the output current of the generator is reduced so as to maintain power generation using the inertial kinetic energy stored in the inertial wheel.

[0013] In one embodiment, the following steps are also included: Monitor the load current of the power output interface and the voltage of the energy storage unit; Based on the combined state of the load current and the voltage, determine whether the system is in normal working state, energy overflow state, no-load warning state, energy saturation state or serious fault state. Based on the determined system status, the equivalent load of the generator is adjusted, and the status indicator lights are controlled to display the corresponding lighting modes to provide users with both tactile and visual feedback.

[0014] As can be seen from the above technical solution, the present invention has at least the following advantages and positive effects compared with the prior art: 1. Completely eliminate the return dead zone and achieve efficient and labor-saving operation: Through the coordinated design of dual transmission wheels, unidirectional transmission components and rope winding in opposite directions, the mechanical principle ensures the continuous unidirectional rotation of the drive shaft under the reciprocating pull of a single rope, realizing uninterrupted energy capture. Moreover, the alternating pulling mode of both hands is ergonomic and significantly reduces user fatigue.

[0015] 2. Flexible and diverse operation modes: By designing the two ends of the pull rope to connect and form a closed loop, users are provided with two efficient operation modes. Users can choose to pull alternately with both hands for the best force application experience, or choose to pull in a single / double-handed unidirectional cycle for simpler and more continuous operation, making it highly adaptable.

[0016] 3. Achieve adaptive and efficient power generation under a wide range of inputs: Through real-time sensing and calculation based on the electrical feedback signal of the generator (1000), the system can dynamically calculate the instantaneous changes (angular acceleration) of human input and intelligently adjust the power generation load. Thus, it can maintain high efficiency under a wide range of user force and rhythm variations, greatly improving energy conversion efficiency.

[0017] 4. Provide intelligent interactive feedback to enhance safety and user experience: By integrating tactile (dynamically adjustable resistance) and visual (multi-mode indicator lights) multimodal feedback mechanisms, the system can convey the complex internal energy and working status (such as saturation, no load, fault) to the user in real time and intuitively, effectively guiding the user to adjust the operating rhythm, avoid unnecessary physical exertion, and enhance the system's operational safety and reliability.

[0018] 5. High robustness and fault tolerance: Thanks to the dynamic decoupling effect brought about by the third unidirectional transmission component (330) and the segmented transmission shaft design, even if the user performs non-standard or erroneous operations (such as sudden pulling and stopping), the operation of the core power generation module will not be forcibly interrupted, ensuring the continuity and stability of the power generation process and making the product highly adaptable to complex operating environments.

In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of the invention.

[0024] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0025] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily need to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0026] The present invention will now be described in detail with reference to specific embodiments: Example 1: Mechanical Structure like Figure 1 , Figure 2 and Figure 4 As shown, a single-rope reciprocating transmission type human power generation device in this embodiment includes a base (100), a transmission shaft mechanism, a first transmission wheel (510), a second transmission wheel (520), a pull rope (200), a reversing pulley (800), a pulley fixing frame (810), an inertia wheel (700), a generator (1000), etc.

[0027] The base (100) is used to mount and support the various components of the device. The transmission shaft mechanism includes a first transmission shaft section (410) and a second transmission shaft section (420) arranged sequentially along the axial direction, both of which are rotatably mounted on the base (100) via bearings. A third one-way transmission member (330) is provided between the first transmission shaft section (410) and the second transmission shaft section (420). The inner ring of the third one-way transmission member (330) is fixedly connected to the end of the first transmission shaft section (410), and its outer ring is fixedly connected to the beginning of the second transmission shaft section (420) via a connector (430). The locking direction of the third one-way transmission member (330) is consistent with the locking direction of the first one-way transmission member (310) and the second one-way transmission member (320) described below.

[0028] The first drive wheel (510) and the second drive wheel (520) are respectively mounted on the first drive shaft segment (410) at intervals via a first one-way drive member (310) and a second one-way drive member (320). Specifically, the inner ring of the first one-way drive member (310) is fixed to the first drive shaft segment (410), and the outer ring is fixed to the inner side of the first drive wheel (510); the inner ring of the second one-way drive member (320) is fixed to the first drive shaft segment (410), and the outer ring is fixed to the inner side of the second drive wheel (520). The locking directions of the two one-way drive members (310, 320) are configured to be the same, both allowing the first drive shaft segment (410) to be driven in the same preset direction (e.g., counterclockwise when viewed from above).

[0029] A pulley fixing bracket (810) is mounted on the base (100), and a reversing pulley (800) located in front between the first drive wheel (510) and the second drive wheel (520) is supported by the pulley fixing bracket (810). The pulley fixing bracket (810) is used to constrain the lateral position of the pull rope (200) to prevent it from coming off.

[0030] The pull rope (200) is a single, continuous rope. During installation, the section of the pull rope (200) that will engage with the reversing pulley (800) passes sequentially through the pulley fixing frame (810) and around the reversing pulley (800), and then both ends are led out. With the reversing pulley (800) as the center of symmetry, the first end (201) and the second end (202) of the pull rope (200) are arranged in opposite spiral directions on the winding path. Specifically, viewed from the outside of the device, the first end (201) of the pull rope (200) is wound clockwise around the first drive wheel (510), while the second end (202) is also wound clockwise around the second drive wheel (520). Since the first drive wheel (510) and the second drive wheel (520) are arranged opposite to each other, the winding direction is actually opposite when viewed from the local coordinate system of each drive wheel: it is clockwise on the first drive wheel (510) and counterclockwise on the second drive wheel (520). This "opposite spiral direction" winding method, combined with the same locking direction of the two unidirectional drive components (310, 320), ensures the correctness of the mechanical transmission. Handles can be installed on the first end (201) and the second end (202) of the pull rope (200).

[0031] The inertia wheel (700) is fixedly mounted on the second transmission shaft section (420) via a hub (730). The input shaft of the generator (1000) is connected to the second transmission shaft section (420) via a gear set (900) to achieve speed increase.

[0032] Working principle: The user holds the first end (201) and the second end (202) of the pull rope (200) with both hands and pulls them alternately. When the first end (201) of the pull rope is pulled outward, the first transmission wheel (510) rotates accordingly, and the first one-way transmission component (310) inside it locks, thereby driving the first transmission shaft section (410) to rotate in a preset direction. Power is transmitted to the second transmission shaft section (420) through the third one-way transmission component (330) (which is locked at this time), which drives the inertia wheel (700) to accelerate through the gear set (900) and drive the generator (1000) to generate electricity. At the same time, the second end (202) of the pull rope is retracted, which drives the second transmission wheel (520) to reverse. At this time, the second one-way transmission component (320) is in an overrunning state and spins freely. The reverse is also true. This cycle is repeated to achieve unidirectional continuous drive under single rope reciprocation.

[0033] Key Advantage: The introduction of the third one-way transmission component (330) enables an automatic overtaking isolation mechanism based on speed difference. When user operation causes the speed of the first transmission shaft segment (410) to drop sharply or fall below that of the second transmission shaft segment (420), the third one-way transmission component (330) immediately enters an overtaking (idling) state, cutting off the reverse power transmission and ensuring that the rotation of the inertia wheel (700) is not disturbed by the front-end operation. The kinetic energy stored in the inertia wheel (700) can thus continuously and smoothly drive the generator (1000) to generate electricity without external interference, ensuring the absolute maximization of the inertial effect of the inertia wheel (700) and minimizing the negative impact of user operation.

[0034] To improve reliability, this embodiment may include a pull cord anti-detachment cover. The pull cord anti-detachment cover is respectively installed on the radial outer side of the first drive wheel (510) and the second drive wheel (520). In a preferred embodiment, the first pull cord anti-detachment cover (610) is provided with a first insertion hole (611a) for the pull cord (200) to pass through and a first exit hole (611b) for the pull cord (200) to pass through; the second pull cord anti-detachment cover (620) is provided with a second insertion hole (621a) for the pull cord (200) to pass through and a second exit hole (621b) for the pull cord (200) to pass through. The diameters of the first insertion hole (611a), the first exit hole (611b), the second insertion hole (621a), and the second exit hole (621b) are all designed to be slightly larger than the diameter of the pull rope (200), thereby providing moderate radial damping when the pull rope (200) passes through, effectively suppressing lateral swaying and slack of the pull rope (200) during violent or abnormal pulling, and further preventing it from coming off the drive wheel groove. Furthermore, the inner and outer edges of the first insertion hole (611a), the first exit hole (611b), the second insertion hole (621a), and the second exit hole (621b) are all rounded or polished to minimize friction with the pull rope (200) and avoid wear. A small gap is left between the pull rope anti-slip cover and the corresponding drive wheel to ensure no contact friction occurs.

[0035] Example 2: Power Generation and Intelligent Control Based on the mechanics of Example 1, this example integrates power generation, energy storage, and intelligent control systems.

[0036] The electrical energy generated by the generator (1000) is first fed into the power management unit. This power management unit includes at least rectification and voltage regulation circuits and can integrate the energy storage unit (1100) and the control unit (1300). The stable DC power generated after processing by the management unit can power the load connected to the power output interface (1400) and also charge the energy storage unit (1100). The control unit (1300) manages the distribution of this electrical energy and executes two core algorithms: a dynamic load adaptive algorithm and a state interaction feedback logic.

[0037] 1. Dynamic load adaptive algorithm The control unit (1300) continuously calculates the real-time angular acceleration of the inertial wheel (700) by sampling the back electromotive force signal of the generator (1000) in real time. Based on the value and sign of the angular acceleration, the algorithm enables the system to adaptively switch between three operating modes: Peak power capture mode: When the angular acceleration exceeds a first set threshold (e.g., based on experimental data from a typical human pull action), it indicates that the user is exerting force suddenly. The control unit (1300) immediately and significantly increases the load current of the generator (1000) to generate maximum electromagnetic torque, efficiently capturing and converting this instantaneous peak mechanical energy.

[0038] Maximum Power Point Tracking (MPPT) mode: When the absolute value of angular acceleration is less than a second set threshold (e.g., based on the fluctuation range during smooth operation) and the speed is higher than the minimum operating value, it indicates that the user is inputting power smoothly and continuously. The control unit (1300) then enters an optimization state, adjusting the load current of the generator (1000) to ensure that the system always operates near the point of highest power generation efficiency at the current speed.

[0039] Inertia Maintenance Mode: When the angular acceleration is less than zero, it indicates that the pull rope (200) is in the retraction or during the user's power-generating interval. The control unit (1300) reduces the load current of the generator (1000) to reduce resistance, so that the rotational kinetic energy stored in the inertia wheel (700) can be continuously released to drive the generator (1000) to generate electricity, thereby filling the operation gap and realizing uninterrupted energy output.

[0040] 2. State interaction feedback logic The control unit (1300) continuously monitors the load current of the power output interface (1400) and the voltage of the energy storage unit (1100), and manages the macroscopic operating status of the system accordingly. The logic is as follows: based on the combination of whether the load current is greater than zero and whether the energy storage unit voltage reaches or exceeds the full voltage, the system is determined to be in a normal working state, energy overflow, no-load warning, energy saturation, or serious fault state.

[0041] For each state, the control unit (1300) executes the corresponding generator (1000) load management strategy (such as maintenance algorithm, output cut-off, system lockout) and drives the status indicator (1200) to provide a matching visual signal (such as constant light, off, flashing at a specific frequency). For example, in the energy overflow state, the system cuts off the generator load and illuminates a red warning light; in the no-load state, it unloads and flashes a yellow warning light. This mechanism transforms the complex electrical and energy states within the system into easily perceptible tactile (resistance change) and visual (light) feedback in real time, thereby guiding operation and ensuring safety. Example 3: Inertial wheel with integrated heat dissipation function like Figure 3As shown, the inertial wheel (700) adopts an integrated structure of hub (730), spokes (720), and rim (710). The rim (710) provides rotational inertia; the spokes (720) connecting the hub (730) and the rim (710) are constructed as fan blades with a specific angle and aerodynamic shape (e.g., an arc-shaped cross-section design). When the inertial wheel (700) rotates, the fan blades drive air to be drawn in axially and discharged at high speed radially, forming a forced cooling airflow directed towards the areas where the generator (1000), the energy storage unit (1100), and the control unit (1300) are located. This design achieves functional integration by simultaneously storing and transferring inertial kinetic energy and directly driving the forced cooling airflow using the mechanical energy of its rotation. Example 4: Operating Modes and System Adaptability The mechanical and control system design of this invention makes the device highly adaptable to different operating modes. The experience and efficiency are optimal in the standard alternating two-handed pulling mode. Even if the user performs non-standard operations such as continuous single-handed pulling or sudden stops, the rotation of the inertial wheel (700) and the power generation process will not be interrupted due to the overrunning isolation mechanism of the third unidirectional transmission component (330). The system guides the user back to efficient operation through intelligent control and feedback adjustment, demonstrating high robustness and user-friendliness. Example 5: Closed-loop operation mode As a preferred embodiment of the present invention, modifications can be made based on any of the above embodiments. See also Figure 1 or Figure 2 Specifically, the first end (201) and the second end (202) of the pull rope (200) are reliably connected to each other through a detachable connector (such as a buckle, hook, etc.) to form a complete closed loop. At this time, the user does not need to hold both ends separately, but can directly hold any segment of the closed loop pull rope with one hand (or both hands) and then pull continuously and cyclically in one direction (e.g., away from the device). Under this operation, when the user pulls out the rope, its effect is equivalent to pulling the original first end (201) of the pull rope; when the rope segment is completely pulled out, the action of continuing to pull will automatically be converted to resetting the original second end (202) of the pull rope through the closed loop. Thanks to the opposite spiral winding method and the cooperation of the same-direction unidirectional transmission components (310, 320), whether the original first end or the second end is pulled, the first transmission shaft segment (410) can be driven to rotate in the same preset direction. Therefore, the closed-loop mode realizes true unidirectional infinite cycle continuous drive, completely eliminating the hand-changing action and gap in traditional reciprocating operation, making the operation process simpler and smoother, especially suitable for occasions that require long-term continuous and stable power generation, further enriching the application scenarios and user experience of the product.
