Description

Technical Field

[0001] This invention relates to the field of gravitational potential energy recovery and mechanical transmission technology, specifically a unidirectional transmission device driven by reciprocating motion. Background Technology

[0002] Traditional gravity reciprocating transmission devices, when converting random gravitational potential energy into mechanical energy, generally suffer from problems such as high energy loss due to reverse transmission resistance, low transmission efficiency, complex structure, and poor adaptability. Especially under variable load conditions such as bumps and swaying, existing devices struggle to achieve efficient unidirectional output and lack effective reset assistance and anti-reverse mechanisms, limiting their engineering applications in vehicles, ships, and wave power generation. Therefore, there is an urgent need for a gravity reciprocating transmission device with a modular structure, selectable bearings, efficient unidirectional transmission, and self-locking function. Summary of the Invention

[0003] The purpose of this invention is to provide a unidirectional transmission device for reciprocating motion drive, so as to solve the problems mentioned in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a reciprocating motion driven unidirectional transmission device, comprising a frame structure, a unidirectional transmission component, a counterweight module, and an energy conversion module; a main shaft is mounted on the frame structure; the unidirectional transmission component includes a bearing selected and mounted on the main shaft according to a preset load level, the bearing being a unidirectional bearing or a ratchet bearing; the counterweight module includes a replaceable counterweight body, and under external reciprocating excitation, the counterweight module drives the main shaft to rotate in a single direction by integrating bidirectional reciprocating force and torque into a single rotational power transmission structure; the energy conversion module is connected to the output end of the main shaft.

[0005] Furthermore, for light-load scenarios, a one-way bearing is configured; for medium-heavy-load scenarios, at least two pawl bearings in the same direction are configured, and an eccentric bearing is added to the end of the pendulum to compensate for oscillation wear; for cargo ship scenarios, a combined gantry frame, guide rail, split-direction swing arm assembly, segmented main shaft and telescopic transmission sleeve, centralized power generation unit and anti-roll and stabilizing ship function module are configured.

[0006] Furthermore, the pawl bearing includes a ratchet and a movable pawl, and has the functions of forward engagement for force transmission, reverse disengagement for force relief, and locking to prevent reverse rotation.

[0007] Furthermore, it also includes a reinforced spring assist system, which includes a high-toughness return spring and an optimized mounting bracket for providing uniform rebound force in light-load or bicycle applications.

[0008] Furthermore, it also includes transmission components selected according to the type of equipment: for bicycles or two-wheeled electric vehicles, the transmission component is a chain and sprocket structure; for four-wheeled motor vehicles, the transmission component is a planetary gear set with a small transmission; for ships or land-based power plants, the transmission component is a heavy-duty gearbox.

[0009] Furthermore, the counterweight can be a conventional pendulum, the vehicle suspension itself, a container, or an external counterweight pendulum, selected according to the application scenario.

[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. By adopting one-way bearings and pawl bearings, and in conjunction with a bidirectional reciprocating force-taking structure, the originally wasted reverse kinetic energy is also converted into effective output, eliminating the energy loss caused by bidirectional resistance in traditional devices and significantly improving the efficiency of gravitational potential energy recovery.

[0011] 2. By adding an eccentric bearing in medium and heavy load scenarios, the uneven wear caused by the reciprocating motion of the pendulum is effectively compensated, and abnormal wear of the spindle and bearing is prevented. The segmented shaft and telescopic sleeve design avoids the problems of long shaft twisting and resonance, and improves the stability and life of the system under large size and heavy load conditions.

[0012] 3. The bearings and transmission components are selected according to the preset load levels, so that the device can flexibly adapt to various working conditions from slight vibration to heavy impact. The modular design reduces manufacturing costs and maintenance difficulty.

[0013] 4. In cargo ship scenarios, the combination of gantry crane, directional swing arm and centralized power generation unit can not only efficiently recover the ship's swaying kinetic energy, but also generate reverse damping by the movement of counterweight, so as to realize the function of reducing rolling and stabilizing the ship and improve navigation safety.

[0014] 5. The pawl bearing has three functions: forward engagement force transmission, reverse disengagement force relief, and locking to prevent reverse rotation. It can achieve spindle self-locking without the need for an additional braking device, and is especially suitable for scenarios such as parking anti-roll-out and energy backflow suppression.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example: Figures 1-6 As shown, the present invention provides a technical solution for a reciprocating motion driven unidirectional transmission device, including a frame structure 1, a unidirectional transmission component 2, a counterweight module 3 and an energy conversion module 4, wherein a main shaft 5 is mounted on the frame structure 1; The one-way transmission component 2 includes a bearing selected and installed on the main shaft 5 according to the preset load level. The bearing used in the one-way transmission component 2 can be a one-way bearing 21, a pawl ratchet 22, a wedge-type overrunning clutch, etc. The counterweight module 3 includes a replaceable counterweight, which drives the main shaft 5 to rotate under external excitation; The energy conversion module 4 is connected to the output end of the main shaft 5; When using this device, first select the bearing and adapter components corresponding to the load level according to the application scenario. For light-load scenarios such as bicycles and two-wheeled electric vehicles, a one-way bearing 21 can be used with a chain chain structure, and a reinforced spring assist system can be used to provide restoring force. The weight of the frame itself is used as a counterweight. After installation, it can recover the gravitational potential energy generated by road bumps during driving to assist the drive. In the parking state, the self-locking function of the bearings can achieve anti-roll-off parking. For medium and heavy-load scenarios such as four-wheeled motor vehicles, multiple sets of ratchet bearings 22 with the same steering direction are selected, along with a planetary gear set and a small transmission. The mass generated by the vehicle suspension and swaying is used as a counterweight. The kinetic energy of swaying gravity during vehicle driving is recovered and converted into electrical energy for storage, without the need for a reinforced spring assist system. When applied to cargo ship swaying energy recovery, a combined gantry frame, guide rails, and The directional swing arm assembly, segmented main shaft 5, and telescopic transmission sleeve, combined with pawl bearing 22 and heavy-duty gearbox, use a ship's container as a counterweight. While recovering the kinetic energy of the swing to generate electricity, the reverse damping generated by the counterweight's movement reduces rolling and stabilizes the ship. When fixed for wave energy generation in the bay coast, it is combined with pawl bearing 22 and heavy-duty gearbox. The ocean waves drive the external counterweight pendulum to reciprocate, continuously driving the main shaft 5 to rotate unidirectionally to generate electricity. The independent gravity power station relies on the external counterweight pendulum's own gravity to reciprocate and output power. Throughout the process, the differentiated bearings ensure that the main shaft 5 rotates only in one direction to output power, eliminating energy loss caused by reverse transmission. At the same time, the bearing's own structure achieves self-locking and anti-reverse rotation, effectively improving energy recovery efficiency and device operation stability, realizing Xianghu Transmission.

[0018] The pawl bearing 22 includes a ratchet and a movable pawl, and has the functions of forward engagement for force transmission, reverse disengagement for force relief, and locking to prevent reverse rotation. The device further defines the specific structure of the pawl bearing 22, including a ratchet and a movable pawl, and endows it with the triple functions of "forward engagement for force transmission, reverse disengagement for force relief, and locking to prevent reverse rotation". Its working principle is as follows: when the counterweight drives the main shaft 5 to rotate in the preset forward direction, the pawl and ratchet reliably engage, and the gravitational torque of the counterweight is completely transmitted to the energy conversion module 4. When the counterweight swings back under the action of gravity or spring, the pawl automatically disengages from the ratchet tooth groove, so that the transmission connection between the main shaft 5 and the counterweight is disconnected. The counterweight can freely reverse and reset without generating drag resistance on the main shaft 5. At the same time, in the stationary or parked state, the locking structure of the pawl and ratchet can effectively prevent the main shaft 5 from reversing. The beneficial effects of this are: greatly improving the unidirectional transmission efficiency in reciprocating motion, eliminating reverse friction loss, and having a natural self-locking anti-reversal function. This is especially important for applications that need to maintain position or prevent energy backflow, and safe locking can be achieved without adding an additional braking device.

[0019] The device is configured with bearings according to the application scenario: For light-load scenarios, a one-way bearing 21 is configured; For medium and heavy load scenarios, at least two pawl bearings 22 with the same direction of rotation are configured, and an eccentric bearing is added to the end of the pendulum to compensate for oscillation wear. For cargo ship scenarios, the system is equipped with a combined gantry frame, guide rails, directional swing arm assembly, segmented main shaft and telescopic transmission sleeve, centralized power generation unit, and anti-roll and stabilizing function module.

[0020] It also includes a reinforced spring assist system 6, which includes a high-toughness return spring and an optimized mounting bracket for providing uniform rebound force in light-load or bicycle applications. A reinforced spring assist system 6 is added, which includes a high-toughness return spring and an optimized mounting position. The working principle is as follows: after the counterweight module 3 completes the forward work stroke, the elastic potential energy stored in the reinforced spring system is rapidly released. Through the optimized mounting position, a uniform and stable rebound force is applied to the counterweight, forcing or assisting the counterweight to quickly and accurately return to the starting position of the next work stroke. This process makes up for the problems of lag, jamming or incomplete return that may occur when relying solely on gravity for return. Its beneficial effects are significant: the high-toughness spring provides long-term and stable rebound force, and the optimized mounting position eliminates uneven wear and stress concentration, thereby significantly improving the reciprocating motion frequency and action consistency of the device. Especially in scenarios with low-frequency external excitation or heavy counterweights, the spring assist can ensure continuous and reliable operation of the device and increase the total energy captured per unit time.

[0021] It also includes transmission components that can be selected according to the type of equipment: For bicycles or two-wheeled electric vehicles, the transmission component is a chain and sprocket structure; For four-wheeled motor vehicles, the transmission assembly is a planetary gear set paired with a small transmission; For shipboard or land-based power plants, the transmission assembly is a heavy-duty gearbox.

[0022] The transmission component is a chain and sprocket structure or a planetary gear set combined with a transmission shaft structure; For equipment requiring flexible, long-distance, and lightweight power transmission, a chain sprocket structure can be selected, utilizing its adjustable center distance and shock absorption characteristics. For equipment requiring high torque, high rigidity, and compact coaxial output, a planetary gear set paired with a drive shaft can be selected, leveraging the advantages of planetary gears' high load-bearing ratio, small size, and high transmission efficiency. The beneficial effect is that this "optional" feature allows the device to no longer be limited to a single mechanical structure, but to become a cross-industry and cross-platform technical platform. Designers can flexibly select the optimal transmission scheme according to the target equipment's spatial layout, torque requirements, speed range, and other parameters, thereby maximizing energy conversion efficiency and achieving structural integration between the device and the host equipment, reducing secondary development and adaptation costs.

[0023] The counterweight can be a conventional pendulum, the vehicle suspension itself, a container, or an external counterweight pendulum, selected according to the application scenario.

[0024] By utilizing the reciprocating swing of the pendulum around the main shaft 5, when the pendulum falls from the high point, its gravitational potential energy is converted into kinetic energy and drives the main shaft 5 to rotate in one direction through the aforementioned bearing; after the lowest point, the pendulum continues to swing upward to complete one motion cycle. The beneficial effects are: as a standardized mechanical component, the conventional pendulum has outstanding advantages such as extremely low cost, easy procurement, accurate calculation of motion trajectory, and mature dynamic balance characteristics. The use of pendulum counterweight makes the design calculation of this device simple and reliable, which is convenient for mass production and quality control. It is especially suitable for cost-sensitive consumer products or fixed power generation scenarios that require long-term maintenance-free operation.

[0025] The system is installed in bicycles, two-wheeled electric vehicles, or shared electric vehicles. It uses a one-way bearing 21 in conjunction with a chain sprocket, with the frame's own weight as a counterweight to recover gravitational potential energy from bumps to assist in driving and to prevent slippage when parking. The system is equipped with a reinforced spring assist system 6. The device is integrated into bicycles, two-wheeled electric vehicles, or shared electric vehicles, and is specified to use a one-way bearing 21 in conjunction with a chain sprocket. Its working process is as follows: when the vehicle is traveling on a bumpy road, the up-and-down movement of the frame relative to the wheels or the vibration at the seat drives the counterweight to move. The one-way bearing 21 ensures that only the positive torque of the counterweight when it falls is transmitted to the wheels through the chain sprocket, thereby converting the gravitational potential energy of the bumps that would otherwise be absorbed and dissipated by the shock absorber or frame into a forward auxiliary driving force. At the same time, the locking function of the one-way bearing 21 or the ratchet bearing 22 can prevent the wheels from slipping backward when the vehicle is parked. Its beneficial effects are: significantly improving the range and riding comfort of short-distance travel tools; for shared electric vehicles, it can reduce the frequency of battery replacement and operating costs; the anti-slip function provides additional safety protection; physical anti-slip can be achieved without electronic handbrakes or mechanical calipers, simplifying the vehicle structure.

[0026] The system is installed in a four-wheeled motor vehicle and uses a ratchet bearing 22 in conjunction with a planetary gear set and a small transmission. The vehicle suspension and its own swaying mass are used as counterweights to recover the kinetic energy of the vehicle's swaying gravity and generate electricity. The system does not have a reinforced spring assist system 6. This system installs the aforementioned device on a four-wheeled motor vehicle and uses a pawl bearing 22 in conjunction with planetary gears and a drive shaft. Its working principle is as follows: when the vehicle travels on bumpy, undulating roads, the vehicle's suspension system will experience continuous up-and-down reciprocating swaying. Connecting this device to the suspension or frame allows the kinetic energy of the vehicle's gravity swaying to drive the counterweight module 3. The pawl bearing 22 ensures that only swaying energy in the effective direction is captured, and the drive shaft is driven through the planetary gear set, ultimately powering the vehicle's generator to charge the vehicle's battery or directly supply electrical equipment. Its beneficial effects include: recovering the suspension vibration energy that would otherwise be wasted as heat energy by the shock absorbers into electrical energy, reducing overall fuel consumption or electricity consumption by 1% to 5%. It is particularly suitable for heavy trucks, off-road vehicles, or vehicles operating in areas with poor road conditions. Furthermore, this system does not increase the engine's load, representing pure "waste energy utilization," and offers advantages such as low cost and convenient installation for the hybridization of existing vehicles.

[0027] The system is installed inside the ship or on the side of the ship. It adopts a combined gantry, guide rail, split swing arm assembly, segmented main shaft and telescopic transmission sleeve, pawl bearing 22, heavy-duty gearbox, and uses a container as a counterweight to convert the ship's swaying kinetic energy into electrical energy, while realizing the function of reducing swaying and stabilizing the ship. This system is installed inside or on the hull of a ship, employing a pawl bearing 22, a heavy-duty transmission structure, and using the ship's own containers as counterweights. The working principle is as follows: When a ship experiences periodic rolling and pitching motions in wind and waves, one or more containers are connected to the ship's structure via the heavy-duty transmission structure. This causes the containers to shift back and forth relative to the hull during the ship's rolling motion. The pawl bearing 22 ensures that the effective unidirectional component of this relative motion is captured, driving a generator via a heavy-duty gear or hydraulic transmission device. The advantages are: ocean-going vessels carry container loads of tens or even hundreds of tons, resulting in enormous rolling kinetic energy. This system can directly convert this "harmful rolling" into electricity for the ship's own use, significantly reducing the operating time of fuel-powered generators, lowering fuel consumption and carbon emissions. Simultaneously, the containers serve as readily available counterweights, eliminating the need for additional dead weight and not affecting the ship's cargo capacity. The heavy-duty transmission structure ensures mechanical reliability under strong winds and waves.

[0028] The system is fixedly installed in a bay or coastal area for wave energy power generation, or it is an independent gravity power station. When generating wave energy, a pawl bearing 22 and a heavy-duty gearbox are used to drive an external counterweight pendulum using waves or tides. When it is an independent gravity power station, an eccentric bearing, a pawl bearing 22 and a heavy-duty gearbox are used to generate power by reciprocating the external counterweight pendulum under its own weight. This system fixes the device in a bay or coastal area, using ocean waves or tidal currents to drive a counterweight, and employs a pawl bearing 22 to generate wave energy. Its working principle is as follows: the device is fixed to a base on the shore or a platform at sea, with the counterweight directly in contact with the water or connected to a float via a connecting rod. The undulation of the waves or the reciprocating motion of the current propels the counterweight to oscillate or rise and fall. The pawl bearing 22 converts this bidirectional, irregular wave motion into a single rotational direction, driving the generator rotor to rotate continuously. The advantages are: compared to traditional oscillating water column or turbine wave energy generation devices, this system uses a fully mechanical transmission, has a simple structure, is corrosion-resistant, and easy to maintain. Furthermore, the pawl bearing 22 can automatically adapt to the irregularity and randomness of the waves, eliminating the need for complex electrical control and phase matching. It is particularly suitable for distributed power supply scenarios such as island microgrids, navigation lights, and marine monitoring equipment, providing a low-cost, high-reliability technical solution for blue energy development.

[0029] The system is an independently set gravity power station that generates electricity by reciprocating the fall of the counterweight itself. This system constructs the aforementioned device as an independent gravity power station. It does not rely on external excitation but instead generates electricity by repeatedly falling under the weight of the counterweight itself. The working process is as follows: the counterweight is lifted to a high position by external power to store gravitational potential energy. Then, the counterweight is controlled to fall freely or in a controlled manner from the high position. The main shaft 5 and the generator are driven by the aforementioned one-way transmission component 2 to generate electricity. After falling to the bottom, it is lifted again, and so on. The beneficial effects are: this is an ideal large-scale energy storage technology. Due to the use of differentiated bearing selection, it can effectively withstand the impact and huge unidirectional torque during heavy-load falls, improving the reliability and lifespan of the power station. Compared with battery energy storage, this system has no chemical pollution, a lifespan of up to decades, and extremely low total life cycle cost. Moreover, as an independent power station, it can utilize cheap off-peak electricity to "charge" and generate electricity and connect to the grid during peak hours, playing a role in peak shaving and valley filling and stabilizing the power grid. It is an important development direction for large-scale physical energy storage in the future.

[0030] Working principle: The core of this device lies in the main shaft 5 supported by the frame structure 1. Based on the preset load level, different bearing modules are selected and installed on the main shaft 5, including one-way bearings 21 and ratchet bearings 22. Under external excitation, such as bumps and swaying, the replaceable counterweight module 3 drives the main shaft 5 to rotate. Due to the use of one-way or ratchet bearings 22, the main shaft 5 can only transmit power in one effective direction, converting the irregular reciprocating motion of the counterweight into unidirectional rotational output. Finally, the energy conversion module 4, such as a generator or transmission mechanism, converts mechanical energy into electrical energy or kinetic energy. The effect is mainly achieved by the differentiated selection of bearings, which allows the device to flexibly adapt to various load conditions from slight vibration to heavy impact. It effectively solves the problems of energy loss and low transmission efficiency caused by reverse resistance in traditional gravity transmission devices. The modular design, with independent frame, bearings, counterweight, and energy conversion, not only reduces manufacturing costs and maintenance difficulty, but also significantly improves the engineering feasibility and system stability of gravity potential energy recovery.
