Description

Technical Field

[0001] This invention relates to the field of road energy recovery and mechanical energy power generation technology, specifically to a road vehicle kinetic energy recovery power generation system. Background Technology

[0002] Currently, energy supply in the road transportation sector mainly relies on distributed renewable energy sources such as solar and wind power. These energy sources are significantly limited by factors such as sunlight intensity, climate conditions, day-night cycles, and geographical environment, resulting in intermittent and unstable energy output. This makes it difficult to continuously and stably meet the electricity demands of ancillary facilities such as road lighting, monitoring, and signage. Meanwhile, the frequent and cyclical pressure loads exerted on the road surface by vehicles during travel contain a large amount of mechanical energy, which has long been unrecovered and unutilized, leading to significant energy waste.

[0003] To achieve energy recovery from road surfaces, some mechanical road surface power generation devices have emerged in existing technologies, but they generally have significant drawbacks: First, they have complex structures, numerous transmission links, a large number of parts, and high installation, commissioning, and maintenance costs, making them difficult to adapt to the requirements of large-scale road construction. Second, they have poor reset stability; after being subjected to pressure, the reset mechanism is prone to jamming, incomplete rebound, or excessive rebound impact, resulting in insufficient reliability for continuous operation. Third, they have low transmission efficiency; the pressure load is greatly lost during transmission, and the conversion efficiency between linear and rotary motion is not high, limiting the power generation effect. Fourth, they have weak durability and adaptability to operating conditions; the devices are prone to wear, deformation, and fatigue damage due to long-term exposure to heavy vehicle loads, impacts, and vibrations, resulting in a short service life.

[0004] In summary, existing road energy utilization methods suffer from problems such as strong environmental dependence and low energy efficiency. Traditional road surface power generation devices also struggle to meet requirements such as simple structure, high transmission efficiency, stable operation, and durability, failing to satisfy the large-scale and long-term application needs of practical road engineering projects. Therefore, developing a road surface rail power generation system that is simple in structure, highly efficient in transmission, reliable in resetting, and durable has significant practical significance and application value.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figures 1 to 8As shown, this embodiment of the invention provides a road vehicle kinetic energy recovery power generation system, including a housing 1, a main shaft assembly, a load-bearing component 3, a generator 4, and a cover plate 5. The housing 1 has an internal accommodating cavity, and the top of the housing 1 is open. The main shaft assembly includes several main shaft units 2, which are arranged in series along the length of the housing 1, and adjacent main shaft units 2 are rigidly connected by a coupling 6. Each main shaft unit 2 includes a unit base 201, a main shaft cover plate 202, a main shaft 203, and a unidirectional sway assembly. The unit base 201 is housed in the accommodating cavity of the housing 1. In the lateral extension direction of the base 201, the main shaft 203 is rotatably mounted on the unit base 201. The unit base 201 is equipped with a main shaft cover plate 202. The outer circular surface of the main shaft 203 is circumferentially fixed to the unidirectional swing component through a flat key. When the unidirectional swing component is driven to swing by an external force, it can drive the main shaft 203 to rotate in one direction and output torque. The load bearing component is installed on the main shaft cover plate 202. The load bearing component is displaced downward under the action of external load and drives the unidirectional swing component to swing. The input shaft of the generator 4 is connected to the output end of the main shaft device. The cover plate 5 is assembled at the opening of the housing 1 to seal the inside of the housing 1.

[0029] The invention features a reasonable overall structural layout. The load generated by vehicle movement is precisely transmitted through the load-bearing component and drives the unidirectional swing component to swing back and forth, converting the excess kinetic energy generated by vehicle crushing and vibration into mechanical energy. This mechanical energy is then converted into electrical energy through a generator, effectively realizing the recycling and utilization of waste energy, thus saving energy and protecting the environment. The components are compactly assembled and smoothly linked, with a short power transmission path, low loss, high structural reliability, and convenient disassembly and maintenance, resulting in low operation and maintenance costs. It has good practical value and promising prospects for promotion.

[0030] In one embodiment of the present invention, the road vehicle kinetic energy recovery power generation system is further equipped with a gearbox 7, which is fixedly arranged between the main shaft device and the generator 4. The power input end of the gearbox 7 is connected to the output end of the main shaft device, and the power output end of the gearbox 7 is correspondingly connected to the input shaft of the generator 4. During vehicle operation, the load-bearing component 3 is driven by the load to move the unidirectional oscillating component, thereby driving the main shaft device to rotate and output mechanical energy. The rotational power output by the main shaft device is first delivered to the inside of the gearbox 7. By utilizing the meshing transmission of the gear set inside the gearbox 7, the input speed and torque are adjusted for speed change and torque amplification. The power after speed adjustment and power amplification then stably drives the generator 4 to operate continuously, thereby completing the efficient conversion of mechanical energy into electrical energy and effectively improving power generation efficiency and stability.

[0031] In one embodiment of the present invention, the spindle unit 2 further includes a bearing housing 204, which is mounted on the unit base 201. The spindle 203 is rotatably assembled inside the bearing housing 204 via the bearing. The bearing housing 204 provides stable support and radial limit for the spindle 203, reducing frictional resistance and radial runout during the rotation of the spindle 203. This ensures that the spindle 203 operates smoothly and is subjected to uniform force under continuous rotation, effectively reducing motion wear and abnormal noise, improving the coaxiality and transmission stability of the spindle 203, thereby ensuring the continuity and reliability of the overall power transmission and extending the overall service life of the spindle unit 2.

[0032] In practical use, when a vehicle rolls over the load-bearing component 3, the external load causes the load-bearing component 3 to shift downwards and apply force, driving the unidirectional swing component to swing in a directional manner. The unidirectional swing component is circumferentially fixed to the main shaft 203 via a flat key, and can drive the main shaft 203 to rotate synchronously in one direction, realizing unidirectional power transmission and preventing energy loss due to reverse rotation. Each main shaft unit 2 is arranged sequentially along the length of the housing 1, and adjacent main shaft units 2 are rigidly connected in series via a coupling 6 to ensure synchronous and stable power transmission. The main shaft 203 is rotatably mounted on the unit base 201 via a bearing seat 204, resulting in low operating friction and strong support stability. Multiple sets of main shaft units 2 aggregate rotational power step by step, and finally output rotational mechanical energy uniformly from the overall output end of the main shaft device. The rear end can cooperate with the gearbox 7 to complete speed change and torque increase, continuously providing stable power input to the generator 4, thereby smoothly converting the mechanical energy generated by vehicle rolling into power generation.

[0033] In an optional embodiment of the present invention, the unidirectional swing assembly specifically includes a unidirectional bearing 205, a reset plate 206, a pin 207, and bolts 208. The unidirectional bearing 205 is coaxially sleeved on the outer surface of the main shaft 203, achieving coaxial assembly with the main shaft 203. The reset plate 206 is fitted against the outer end face of the unidirectional bearing 205, and the pin 207 is fixedly arranged on the reset plate 206. During assembly, the pin 207, the reset plate 206, and the unidirectional bearing 205 are sequentially locked and fixed by the bolts 208, making the three components tightly integrated into a single structure, ensuring that the pin 207 and the reset plate 206 can swing synchronously with the unidirectional bearing 205. In this embodiment, by relying on the one-way limiting characteristic of the one-way bearing 205, the main shaft 203 can be driven to rotate in only one direction, restricting the reverse rotation of the main shaft 203. Combined with the overall swing structure, the driving torque is stably transmitted, which not only realizes the orderly conversion of load force into rotational power, but also avoids power loss caused by reverse idling, thus improving the stability and effectiveness of power transmission.

[0034] In a specific embodiment of the present invention, the main shaft unit 2 is further provided with an elastic element 209. One end of the elastic element 209 is connected to the bolt 208 on the unidirectional swing assembly, and the other end of the elastic element 209 is fixedly connected to the unit base 201. Preferably, the elastic element 209 can be a tension spring. When the external load is released, the tension spring itself provides elastic restoring force to continuously apply traction force to the unidirectional swing assembly, causing the unidirectional swing assembly to quickly rebound and reset after completing the swing action, so that each structural component returns to its initial working state, so as to continuously respond to the next vehicle rolling load, realize reciprocating cycle operation, and ensure that the entire system continuously and stably completes kinetic energy recovery and power output.

[0035] In a specific embodiment of the present invention, the load-bearing assembly 3 mainly includes a pressure-bearing plate and a contact member, which are connected to each other. When an external load generated by a vehicle rolling over the plate acts on it, the plate is displaced downwards, which simultaneously drives the contact member to move downwards. The downward-moving contact member directly presses against and contacts the pin 207 on the one-way swing assembly, thereby applying a downward squeezing force to the pin 207 and driving the entire one-way swing assembly to swing in a directional manner. This completes the conversion of load force into mechanical swing force, providing a stable drive source for the subsequent rotational power output of the main shaft 203.

[0036] In an optional embodiment of the present invention, the pressure-bearing plate specifically includes a fixing member 301, a positioning pin 302, a self-aligning bearing 303, a connecting block 304, and a top plate 305. The fixing member 301 is securely installed, and the positioning pin 302 passes through the fixing member 301 to form a reliable support. The self-aligning bearing 303 is correspondingly assembled at the end position of the positioning pin 302. The connecting block 304 is rotatably assembled on the positioning pin 302 through the self-aligning bearing 303, which can achieve adaptive fine adjustment and flexible swinging, reducing assembly stress and motion friction. The top plate 305 is fixedly installed above the connecting block 304 to directly bear the external vehicle load. After being stressed, it can move together with the connecting block 304 to stably transmit pressure and ensure smooth overall movement and uniform stress distribution of the pressure-bearing plate.

[0037] In an optional embodiment of the present invention, the contact components specifically include a bushing 306, a push rod 307, a node support 308, a support shaft 309, and a tightening sleeve 310. These components work together to transmit loads. The bushing 306 is securely mounted on the main shaft cover plate 202, providing stable support and guidance for the push rod 307. The push rod 307 is vertically arranged, with one end passing through the bushing 306 for precise guidance, ensuring coaxiality during vertical displacement. The other end of the push rod 307 is inserted into the node support 308. To ensure a reliable connection between the push rod 307 and the node support 308, a tightening sleeve 310 is fitted onto the end of the push rod 307 facing the node support 308. The tightening and locking action of the tightening sleeve 310 securely fastens the node support 308 and the end of the push rod 307 together, ensuring synchronous linkage and no relative displacement. Meanwhile, support shafts 309 are symmetrically mounted at both ends of the node support 308. The support shafts 309 are fixedly connected to the top plate 305 of the pressure plate. Rollers 316 and rubber pads 315 are sequentially arranged at both ends of the support shafts 309. The rubber pads 315 serve to buffer and dampen shocks and isolate wear. The rollers 316 can convert the sliding friction between the support shafts 309 and the top plate 305 into rolling friction, reducing motion resistance and ensuring smooth power transmission. When the top plate 305 displaces downward under external load, the support shafts 309 can drive the node support 308 to move downward synchronously, thereby driving the push rod 307 to move downward along the bushing 306, realizing stable load transmission and providing driving force for the swing of the unidirectional swing assembly.

[0038] In an optional embodiment of the present invention, the contact element is further provided with an outer node bushing 311, an inner node bushing 312, a node compression spring 313, and a buffer pad 314. The node compression spring 313 and the inner node bushing 312 are sequentially fitted onto the outside of the bushing 306. The outer node bushing 311 covers and is installed on the upper part of the node compression spring 313, providing limitation and protection for the node compression spring 313 and ensuring stable and reliable extension and retraction. A buffer pad 314 is fitted to the end of the push rod 307 away from the node support 308. The buffer pad 314 effectively buffers the impact load when the push rod 307 moves downward, reducing component collision wear and operating noise. Through the cooperative arrangement of the bushing and spring, the reciprocating motion of the push rod 307 can be buffered, damped, and limited, making the overall transmission of the contact element smoother and improving the stability and service life of the structure.

[0039] When the road vehicle kinetic energy recovery and power generation system of this embodiment is working, when the vehicle passes over the cover plate above the compaction equipment, the external load first acts on the top plate 305 of the pressure plate component. The top plate 305 is pressed down by the force, which drives the connecting block 304 to swing adaptively around the positioning pin shaft 302 by relying on the self-aligning bearing 303. At the same time as the pressure plate component moves, the node support 308 moves downward synchronously through the support shafts 309 at both ends. The node support 308 is rigidly locked to the end of the top rod 307 by the expansion sleeve 310, which in turn pushes the top rod 307 to move vertically downward along the bushing 306. After the top rod 307 moves downward, it directly squeezes the pin 207 of the one-way swing component, driving the reset plate 206 and the one-way bearing 205 to swing in an overall direction. The elastic element 209 of the one-way swing component is connected to the bolt 208 at one end and fixed to the unit base 201 at the other end. After the external load is removed, the elastic element 209 releases the elastic tension, pulling the one-way swing component to rotate back and reset. During the repeated rolling and removal of the load, the load-bearing components continuously press down and reset, driving the main shaft unit 2 to rotate intermittently in one direction. Multiple main shaft units 2 are linked together through the coupling 6 to collect power and continuously output mechanical energy to provide continuous power input to the rear gearbox 7 and generator 4, thus completing the recovery and power generation of the vehicle's rolling kinetic energy.

[0040] Multiple main shaft units 2 are rigidly connected in series via couplings 6 along the length of the housing 1. Each main shaft unit 2 synchronously completes the cyclic action of "rotating the main shaft 203 under load - resetting after load removal". The rotational mechanical energy output is collected and transmitted from the output end of the main shaft device to the gearbox 7. The gearbox 7 adjusts the input power by changing speed and increasing torque, driving the generator 4 to operate continuously, efficiently converting mechanical energy into electrical energy, thus completing the recovery and utilization of the kinetic energy of road vehicle rolling. Throughout the process, the housing 1 and the cover plate 5 form a closed protection to prevent external debris and rainwater from entering, ensuring the long-term stable operation of each component and realizing continuous and reliable kinetic energy recovery and power generation of the system.
