Description

Technical Field

[0001] This utility model relates to the field of energy recovery technology, and in particular to an energy conversion device, a hydraulic power generation system, and a vehicle energy recovery device. Background Technology

[0002] Vehicles consume energy during operation, and are frequently subjected to bumps and vibrations due to road conditions, especially on bumpy roads. These bumps and vibrations increase energy loss. To effectively utilize this lost energy and improve energy efficiency, various energy recovery devices have been introduced to the market. One major energy recovery method is converting vibration into hydraulic power to generate clean electricity. These devices typically use a piston that slides under the influence of bumps or vibrations, creating pressure changes that drive hydraulic changes, which in turn drive a hydraulic motor to rotate a generator and produce clean electricity. However, this method often requires sufficient displacement space for the piston, resulting in a large installation space requirement and difficulty in effectively recovering energy from vertical vibration displacement. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an energy conversion device, a hydraulic power generation system and a vehicle energy recovery device, which have the advantages of effectively realizing energy recovery during driving and occupying little installation space.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] According to the embodiments disclosed in this utility model, a first aspect provides an energy conversion device, comprising:

[0006] The cylinder body has an opening at one end and a distribution plate assembly connected to the second end. The distribution plate assembly is provided with an oil injection port for connecting to the power generation device and an oil suction port for receiving hydraulic oil.

[0007] A flange connection module that is rotatably mounted on the first end of the cylinder body is used to connect with the rotating component and to rotate relative to the cylinder body to form a swing angle under the action of gravity or when receiving a vibration force.

[0008] A piston power module connected to the flange connection module, the piston power module comprising: an inner liner having a plurality of movable chambers, and a piston body sealed and movably connected to the movable chambers, the piston body being rotatably connected to the flange connection module and sliding within the movable chambers when forming a swing angle to generate suction / compression force to drive the flow of liquid medium and generate hydraulic driving force; and,

[0009] The transmission spindle meshes with the middle part of the inner liner for transmission, and the first end of the transmission spindle is rotatably connected to the flange connection module through a ball cage ball body.

[0010] To achieve the above technical solution, during use, the flange connection module is connected to the rotating parts of the moving device, such as the wheels of a car. In a unloaded, balanced state, the rotating parts drive the piston power module and the transmission main shaft to rotate synchronously via the flange connection module. At this time, the piston body will not shift within the moving chamber, maintaining a stable rotation without generating hydraulic driving force. When the vehicle's tires contact the ground, the tires are pressed down by the vehicle's own weight, causing the flange connection module and cylinder to shift, creating a swing angle. Simultaneously, when bumps or vibrations occur, the relative deflection between the flange connection module and the cylinder further increases the swing angle. Because the piston body is relatively rotated and connected to the flange connection module, the deflection of the flange connection module causes the piston body to shift synchronously, and the downward pressure from the vehicle's weight causes a synchronous relative deflection between the tire's flange module and the cylinder, creating a swing angle. During vehicle movement, the wheels drive the flange connection... The module rotates, causing the inner liner to rotate synchronously. This causes several pistons corresponding to the inward-off portion of the flange-connected module to push inward, creating a compressive force, while several pistons corresponding to the outward-off portion slide outward, creating a suction force. This causes hydraulic oil to be ejected from the injection port, pass through the generator, and then flow back through the suction port. During continuous rotation, the positions of each piston change synchronously, continuously generating suction / compression forces, which in turn generate a continuous hydraulic driving force to achieve energy conversion. This hydraulic driving force is transmitted to the generator to produce clean electricity, thus achieving energy recovery. The larger the swing angle, the greater the suction force generated, meaning that the greater the load and the more bumps / vibrations, the more energy is recovered, especially for vertical kinetic energy. Furthermore, since the piston's extension and retraction are controlled by angular deflection, a large displacement space is not required, resulting in a smaller installation space.

[0011] In one embodiment of this utility model, the oil distribution plate assembly includes:

[0012] An oil separator plate is connected to the inner liner, and two sets of oil distribution grooves are symmetrically arranged on the oil separator plate, each oil distribution groove corresponding to at least one set of the movable chambers; and...

[0013] An oil distribution cap is sealed to the second end of the cylinder body. The oil distribution cap is provided with an oil storage tank corresponding to the oil distribution groove. The oil injection port and the oil suction port are respectively provided with one of the oil storage tanks.

[0014] To achieve the above technical solution, the piston body draws liquid medium into the moving chamber during its movement, distributes it through the oil distribution tank, and then flows into the corresponding oil storage tank. Finally, the liquid medium is circulated through the oil injection port and the oil suction port.

[0015] In one embodiment of this utility model, the flange connection module includes:

[0016] A spherical swing head seat, which is rotatably mounted on the first end of the cylinder, is used to deflect relative to the cylinder to form a swing angle.

[0017] The flange seat, rotatably connected to the spherical swing head seat, is used for assembly with the rotating component; and,

[0018] A ball cage rotary seat is fixedly mounted on the flange seat, and the ball cage rotary seat is rotatably mounted on the spherical swing head seat.

[0019] To achieve the above technical solution, during installation, the flange seat is assembled with the rotating part of the motion device. When the rotating part rotates, it will synchronously drive the flange seat to rotate. Since the flange seat is rotatably connected to the spherical swivel head seat, the spherical swivel head seat will not rotate with the flange seat. However, since the ball cage rotary seat is fixed to the flange seat and rotatably connected to the spherical swivel head seat, it will rotate synchronously with the flange seat, while the spherical swivel head seat will not rotate with the ball cage rotary seat. When bumps or vibrations occur, the spherical swivel head seat and the cylinder body will deflect relative to each other to form a swing angle. At this time, due to the setting of the ball cage ball, the transmission main shaft can simultaneously form a swing angle, thereby driving the inner liner to rotate.

[0020] In one embodiment of the present invention, rotating connecting platforms are provided on both sides of the cylinder body, and a rotating shaft platform corresponding to the rotating connecting platform is provided on the spherical swing head seat. The rotating connecting platform and the rotating shaft platform are rotatably connected by a positioning shaft.

[0021] The above technical solution enables the rotational positioning of the spherical oscillating head seat and the rotating connecting platform.

[0022] In one embodiment of the present invention, a swing buffer frame is also sleeved and fixed outside the spherical swing head seat, and a damping hydraulic rod is provided between the swing buffer frame and the cylinder body. One end of the damping hydraulic rod is hinged to the swing buffer frame and the other end is hinged to the cylinder body.

[0023] To achieve the above technical solution, when bumps or vibrations occur, the swing buffer frame and the damping hydraulic rod work together to buffer the impact, making the generated hydraulic power more stable.

[0024] In one embodiment of this utility model, a spherical connecting rod is connected to the piston body, and the end of the spherical connecting rod is rotatably connected to the ball cage rotary seat via a rolling ball. A rotary fixing disk is fixed on the ball cage rotary seat. When the spherical swing head seat deflects, the piston body is driven to shift through the ball cage rotary seat and the spherical connecting rod to form a suction / compression force.

[0025] To achieve the above technical solution, the rolling ball is positioned on the ball cage rotary seat by a rotary fixed plate, so that the spherical connecting rod can drive the piston body to swing relative to each other. At this time, part of the piston body can be drawn inward and part of the piston body can be squeezed outward. During the synchronous rotation of the ball cage rotary seat and the flange seat, the inner liner and the piston body can be driven to rotate, thereby forming a suction / squeezing force.

[0026] In one embodiment of the present invention, the ball cage ball body is rotatably connected to the middle part of the ball cage swivel seat via ball bearings, the middle part of the ball cage ball body is provided with a first transmission tooth, and the first end of the transmission main shaft is provided with a second transmission tooth that meshes with the first transmission tooth.

[0027] To achieve the above technical solution, the first transmission gear and the second transmission gear mesh with each other, enabling the ball cage ball to rotate synchronously with the transmission main shaft. The ball cage ball can also be used as a bearing, ensuring the stability of the transmission main shaft rotation.

[0028] According to the embodiments disclosed in this utility model, a second aspect provides a hydraulic power generation system, including:

[0029] The energy conversion device as described in the first aspect;

[0030] A hydraulic motor, wherein the inlet end of the hydraulic motor is connected to the fuel injector, and the outlet end is connected to an oil reservoir, the oil reservoir being connected to the fuel inlet; and,

[0031] A generator is connected to the hydraulic motor so that it is driven by the hydraulic motor to generate electricity.

[0032] To achieve the above technical solution, when the wheel rotates and bumps or vibrations occur, the energy conversion device converts the displacement and energy loss caused by the bumps or vibrations into hydraulic driving force. The liquid medium forms a hydraulic circulation through the oil injection port, hydraulic motor, oil storage tank and oil suction port, driving the hydraulic motor to rotate, which in turn drives the generator to work and generate clean electrical energy, thus realizing the recovery and utilization of energy.

[0033] In one embodiment of this utility model, a flow stabilizer is also connected between the oil injection port and the hydraulic motor.

[0034] To achieve the above technical solution, a flow stabilizer is used to stabilize the fluid flow, making the supply of hydraulic driving force more stable.

[0035] According to the embodiments disclosed in this utility model, a third aspect provides a vehicle energy recovery device, including a hydraulic energy generation system as described in the second aspect, wherein the flange connection module is fixedly connected to the wheel, a mounting base is fixed on the cylinder, and the mounting base is hingedly connected to the vehicle suspension system.

[0036] To achieve the above technical solution, in application, the wheel and flange connection module are assembled together, and the cylinder is hinged to the vehicle suspension system through the mounting base. When the wheel rotates and bumps, the wheel and vehicle suspension system are displaced, which causes the cylinder and flange connection module to deflect and form a swing angle, thereby enabling continuous energy recovery during vehicle operation.

[0037] As described above, the present invention has the following beneficial effects:

[0038] This utility model provides an energy conversion device, a hydraulic power generation system, and a vehicle energy recovery device. In use, a flange connection module connects to the rotating components of a moving device, such as a car wheel. In a unloaded, balanced state, the rotating components drive the piston power module and the transmission shaft to rotate synchronously via the flange connection module. At this time, the piston body does not shift within the moving chamber, maintaining a stable rotation without generating hydraulic driving force. When the vehicle's tire contacts the ground, the tire is pressed down by the vehicle's own weight, causing the flange connection module and cylinder to shift, creating a swing angle. Simultaneously, when bumps or vibrations occur, the relative deflection between the flange connection module and the cylinder further increases the swing angle. Because the piston body is relatively rotated and connected to the flange connection module, the deflection of the flange connection module causes the piston body to shift synchronously, and the downward pressure from the vehicle's weight causes a synchronous relative deflection between the tire's flange module and the cylinder, creating the swing angle. During vehicle movement, the wheels drive the flange connection module to rotate, which in turn drives the inner liner to rotate synchronously. This causes several pistons corresponding to the inward-off portion of the flange connection module to push inward, creating a compressive force, while several pistons corresponding to the outward-off portion slide outward, creating a suction force. This causes hydraulic oil to be ejected from the injection port, pass through the generator, and then flow back through the suction port. As the rotation continues, the positions of each piston change synchronously, continuously generating suction / compression forces, which in turn generate a continuous hydraulic driving force to achieve energy conversion. This hydraulic driving force is transmitted to the generator to produce clean electricity, thus achieving energy recovery. The larger the swing angle, the greater the suction force generated; that is, the greater the load and the more bumps / vibrations, the more energy is recovered, especially for vertical kinetic energy. Furthermore, because the piston's extension and retraction are controlled by angular deflection, a large displacement space is not required, resulting in a smaller installation space.

[0052] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0053] Please see Figures 1 to 6 The first aspect of this utility model provides an energy conversion device, comprising: a cylinder body 10, with a first end open and a second end connected to an oil distribution plate assembly 20, the oil distribution plate assembly 20 having an oil injection port 222 for communicating with a power generation device and an oil suction port 223 for receiving hydraulic oil; a flange connection module 30 rotatably mounted on the first end of the cylinder body 10 for connecting to a rotating component and rotating relative to the cylinder body 10 to form a swing angle under the action of gravity or when receiving a vibration force; a piston power module 40 connected to the flange connection module 30; and a transmission main shaft 50.

[0054] Specifically, the piston power module 40 is disposed inside the cylinder body 10. The piston power module 40 includes: an inner liner 41 having several movable chambers 411, and a piston body 42 that is sealed and movably connected to the movable chambers 411. The piston body 42 is rotatably connected to the flange connection module 30 and slides in the movable chambers 411 when forming a swing angle to form suction / extrusion force to drive the liquid medium to flow and form hydraulic driving force. The inner liner 41 can be rotatably connected to the cylinder body 10 through bearings. The movable chambers 411 are evenly distributed on the inner liner 41. The piston body 42 is made of elastic materials such as metal or rubber. When the piston body 42 is inserted into the movable chambers 411, it forms a sealed connection with the inner liner 41. When the piston body 42 undergoes relative displacement in the movable chambers 411, suction / extrusion force can be formed.

[0055] The oil distribution plate assembly 20 includes: an oil distribution plate 21 connected to the inner liner 41, with two sets of oil distribution grooves 211 symmetrically arranged on the oil distribution plate 21, each oil distribution groove 211 corresponding to at least one set of movable chambers 411; and an oil distribution cover 22 sealed to the second end of the cylinder body 10, with an oil storage tank 221 corresponding to the oil distribution groove 211 on the oil distribution cover 22, and an injection port 222 and an intake port 223 respectively corresponding to an oil storage tank 221.

[0056] The oil separator 21 and the oil distribution cap 22 are fixedly engaged, and the inner liner 41 and the oil separator 21 are sealed together to prevent leakage of the hydraulic medium after it flows out of the movable chamber 411. For example, an outwardly protruding boss can be provided on the side of the inner liner 41 near the oil separator 21, and the oil separator 21 has a groove that matches the boss. The boss is embedded in the groove to form a sealed connection, and at the same time, it prevents the inner liner 41 from shifting when it rotates. The movable chamber 411 can usually be cylindrical, and the inner liner 41 has oil inlets corresponding to each movable chamber 411. The oil inlets can be circular, quadrilateral, oval, etc., preferably oval. The oil distribution groove 211 is an arc-shaped groove that is close to a semicircle. The dimensions of the two oil distribution grooves 211 are... The dimensions are the same and correspond to the oil inlet. It can be understood that the length of the oil inlet should be less than or equal to the size of the movable chamber 411, and the width of the oil inlet should be less than or equal to the width of the oil distribution groove 211. After the liquid medium flows out of the oil inlet, it can smoothly enter the oil distribution groove 211 for distribution. The function of the oil distribution groove 211 is to separate the ejection and return of the hydraulic medium. Preferably, the movable chamber 411 is set to an odd number, such as 3, 5, 7, etc. Taking 5 movable chambers 411 as an example, 5 oval oil inlets are set accordingly. At this time, during the rotation, any oil inlet will not cross two oil distribution grooves 211 at the same time, that is, to ensure that the ejection and return of the liquid medium will not interfere with each other. Each oil distribution groove 211 can cover one or two oil inlets respectively.

[0057] The shape of the oil storage tank 221 can be the same as that of the oil distribution tank 211, and the oil distribution cover 22 and the oil distribution plate 21 are relatively close and sealed. After the liquid medium is distributed by the oil distribution tank 211, it enters the oil storage tank 221. The oil injection port 222 and the oil suction port 223 can be threaded with nozzles to facilitate pipeline connection of the hydraulic motor 60, etc. During the movement, the piston body 42 draws liquid medium in the movable chamber 411, which is then distributed by the oil distribution tank 211 and flows to the corresponding oil storage tank 221. The liquid medium is then circulated through the oil injection port 222 and the oil suction port 223.

[0058] The flange connection module 30 includes: a spherical sway head seat 31 rotatably mounted on the first end of the cylinder body 10 for deflecting relative to the cylinder body 10 to form a swing angle; a flange seat 32 rotatably connected to the spherical sway head seat 31 for assembling with a rotating component; and a ball cage rotary seat 33 fixedly mounted on the flange seat 32, the ball cage rotary seat 33 being rotatably mounted on the spherical sway head seat 31.

[0059] At the first end of the cylinder body 10, there is an arc-shaped connecting groove that is adapted to the spherical oscillating head seat 31 for contacting and supporting the spherical oscillating head seat 31 for swinging. Specifically, there are rotating connecting platforms 11 on both sides of the cylinder body 10, and the spherical oscillating head seat 31 is provided with a rotating shaft platform 311 corresponding to the rotating connecting platform 11. The rotating connecting platform 11 and the rotating shaft platform 311 are rotatably connected through the positioning shaft 312, thereby realizing the rotational positioning of the spherical oscillating head seat 31 and the rotating connecting platform 11.

[0060] The flange seat 32 has a flange plate at its front end for assembly with the rotating parts of the power unit. The ball cage slewing seat 33 is fitted into the inner side of the flange seat 32, and a connecting stud is provided at the front end of the ball cage slewing seat 33. The flange seat 32 has a connecting hole that matches the connecting stud. After the connecting stud passes through the connecting hole, it is locked into the lock nut, thus realizing the connection and fixation between the flange seat 32 and the ball cage slewing seat 33. The flange seat 32 and the spherical oscillating head seat 31, and the ball cage slewing seat 33 and the spherical oscillating head seat 31 are all rotatably connected by ball cages, and relative rotation is achieved by several balls on the ball cages.

[0061] During installation, the flange seat 32 is assembled with the rotating part of the motion device. When the rotating part rotates, it will synchronously drive the flange seat 32 to rotate. Since the flange seat 32 is rotatably connected to the spherical swivel head seat 31, the spherical swivel head seat 31 will not rotate with the flange seat 32. However, since the ball cage swivel seat 33 is fixed to the flange seat 32 and rotatably connected to the spherical swivel head seat 31, it will rotate synchronously with the flange seat 32, while the spherical swivel head seat 31 will not rotate with the ball cage swivel seat 33. When under the action of gravity or when bumps or vibrations occur, the spherical swivel head seat 31 and the cylinder 10 will be relatively deflected to form a swing angle. At this time, due to the setting of the ball cage ball body 51, the transmission main shaft 50 can simultaneously form a swing angle, thereby driving the inner liner 41 to rotate.

[0062] Furthermore, a swing buffer frame 34 is also fitted and fixed outside the spherical swing head seat 31. A connecting flange is provided on the outside of the spherical swing head seat 31. After the swing buffer frame 34 is fitted onto the spherical swing head seat 31, it is locked and fixed with the connecting flange. Connecting side plates corresponding to the rotating connecting platform 11 are provided on both sides of the spherical swing head seat 31. The positioning shaft 312 passes through the connecting side plate, and an end plate is provided on the outside of the positioning shaft 312. The end plate is locked and fixed with the connecting side plate by bolts. A damping hydraulic rod 35 is also provided between the swing buffer frame 34 and the cylinder body 10. One end of the damping hydraulic rod 35 is hinged to the swing head seat 31. The swing buffer frame 34 is hinged to the cylinder body 10 at one end. Typically, a first hinge seat is provided on the swing buffer frame 34, and a first hinge joint adapted to the first hinge seat is provided at the first end of the damping hydraulic rod 35 to realize the hinge connection at the first end. A second hinge seat is fixed on the cylinder body 10 or the oil distribution seal 22, and a second hinge joint adapted to the second hinge seat is provided at the second end of the damping hydraulic rod 35 to realize the hinge connection at the second end. When bumps or vibrations occur, the swing buffer frame 34 and the damping hydraulic rod 35 cooperate to play a buffering role, making the generated hydraulic power more stable.

[0063] A spherical connecting rod 421 is connected to the piston body 42. The end of the spherical connecting rod 421 is rotatably connected to the ball cage rotary seat 33 via a rolling ball 422. A rotary fixing plate 331 is fixed on the ball cage rotary seat 33. The rotary fixing plate 331 is provided with several insertion ports for accommodating the rolling ball 422. The inner side of the insertion port is adapted to the rolling ball 422. After the spherical connecting rod 421 passes through the insertion port, it is fixed to the piston body 42 by means of threaded connection or other methods. The ball cage rotary seat 33 is provided with several hemispherical rotating grooves that are adapted to the rolling ball 422. After the rotary fixed plate 331 is fixedly assembled with the ball cage rotary seat 33 by screws, the rolling ball 422 is restricted in the hemispherical rotating groove, so that the spherical connecting rod 421 rotates relative to the ball cage rotary seat 33. When the spherical swing head seat 31 deflects, the piston body 42 is driven to shift through the ball cage rotary seat 33 and the spherical connecting rod 421 to form a suction / extrusion force.

[0064] The ball 422 is positioned on the ball cage rotary seat 33 by the rotating fixed plate 331, so that the ball connecting rod 421 can drive the piston body 42 to swing relative to each other. At this time, part of the piston body 42 can be drawn inward and part of the piston body 42 can be squeezed outward. During the synchronous rotation of the ball cage rotary seat 33 and the flange seat 32, the inner liner 41 and the piston body 42 can be driven to rotate, thereby forming a suction / squeeze force.

[0065] The transmission spindle 50 meshes with the middle of the inner liner 41, and the first end of the transmission spindle 50 is rotatably connected to the flange connection module 30 through the ball cage ball body 51. The ball cage ball body 51 is rotatably connected to the middle of the ball cage swivel seat 33 through the balls. The middle of the ball cage ball body 51 is provided with a first transmission tooth 52, and the first end of the transmission spindle 50 is provided with a second transmission tooth 53 that meshes with the first transmission tooth 52. Through the meshing of the first transmission tooth 52 and the second transmission tooth 53, the ball cage ball body 51 can rotate synchronously with the transmission spindle 50, and the ball cage ball body 51 can also be used as a bearing to ensure the stability of the rotation of the transmission spindle 50. The transmission spindle 50 and the inner liner 41 also achieve power transmission through meshing transmission teeth. The end of the transmission spindle 50 is rotatably connected to the oil distribution seal 22 through a bearing to ensure the stable rotation of the transmission spindle 50.

[0066] In use, the flange connection module 30 is connected to the rotating parts of the moving device, such as the wheels 81 of a car. Under unloaded and unbalanced conditions, the rotating parts drive the piston power module 40 and the transmission main shaft 50 to rotate synchronously via the flange connection module 30. At this time, the piston body 42 will not displace within the moving chamber 411, maintaining a stable rotation without generating hydraulic driving force. When the vehicle's tires contact the ground, the tires are pressed down by the vehicle's own weight, causing the flange connection module 30 and the cylinder 10 to shift, creating a swing angle. Simultaneously, when bumps or vibrations occur, the relative deflection between the flange connection module 30 and the cylinder 10 also increases the swing angle. Because the piston body 42 is relatively rotated and connected to the flange connection module 30, the deflection of the flange connection module 30 will cause the piston body 42 to shift synchronously, and the downward pressure from the vehicle's weight will cause the flange module and cylinder 10 to deflect synchronously, creating a swing angle. During vehicle movement, the wheels 81 drive the flange... The rotating connecting module 30 drives the inner liner 41 to rotate synchronously. This causes several pistons 42, corresponding to the inward offset portion of the flange connecting module 30, to push inward, creating a compressive force. Conversely, several pistons 42, corresponding to the outward offset portion of the flange connecting module 30, slide outward, creating a suction force. This causes hydraulic oil to be ejected from the injection port 222, pass through the generator, and then return through the suction port 223. During continuous rotation, the positions of each piston 42 change synchronously, continuously generating suction / compression force, which in turn generates continuous hydraulic driving force to achieve energy conversion. This hydraulic driving force is transmitted to the generator to produce clean electricity, thus achieving energy recovery. The larger the swing angle, the greater the suction force generated, meaning that the greater the load and the more bumps / vibrations, the more energy is recovered. It is particularly effective at recovering kinetic energy in the vertical direction. Furthermore, since the extension and retraction of the pistons 42 are controlled by angular deflection, a large displacement space is not required, resulting in a smaller installation space.

[0067] Please see Figure 7 The second aspect of this utility model provides a hydraulic power generation system, including: an energy conversion device as described in the first aspect; a hydraulic motor 60, the oil inlet of the hydraulic motor 60 being connected to an oil injection port 222 and the oil outlet being connected to an oil storage tank 61, the oil storage tank 61 being connected to an oil suction port 223; and a generator 70, connected to the hydraulic motor 60 to be driven by the hydraulic motor 60 to generate electricity.

[0068] Specifically, the flange connection module 30 of the energy conversion device is connected to the rotating component of the power unit. The power unit can be, for example, a transportation device such as a car or ship, and the corresponding rotating component can be a rotating part such as a wheel 81 or a propeller. The hydraulic motor 60 is connected to the oil injection port 222 through an oil pipe, and a flow stabilizer 62 is also connected between the oil injection port 222 and the hydraulic motor 60. The flow stabilizer 62 can adopt an existing structure and can be used to regulate and control the stable flow of fluid. The flow stabilizer 62 mainly controls the speed of fluid entering and leaving the system to achieve stable fluid flow. By using a specific design structure and adjustment mechanism, the fluid is precisely controlled to ensure that parameters such as flow rate, flow velocity, and fluid pressure are kept within a preset range. By setting the flow stabilizer 62 to stabilize the fluid flow, the supply of hydraulic driving force is made more stable.

[0069] When the vehicle's weight acts on the vehicle's suspension system or when bumps or vibrations occur, the energy conversion device converts the displacement and energy loss caused by the load, bumps, or vibrations into hydraulic driving force. The liquid medium forms a hydraulic circulation through the oil injector 222, hydraulic motor 60, oil tank 61, and oil suction port 223, driving the hydraulic motor 60 to rotate, which in turn drives the generator 70 to work and generate clean electrical energy, realizing energy recovery and utilization. It can be understood that the electrical energy generated by the generator 70 can be supplied to the vehicle's power battery for intelligent charging. Typically, the generator 70 is connected to an AC / DC rectifier and an intelligent voltage regulator module. After rectification and voltage regulation, the current is output as DC power, which is then input into the vehicle's battery management system (BMS) to realize intelligent charging of the power battery. As a complement to the traditional regenerative braking system (KERS), it effectively improves the battery's range.

[0070] Please see Figures 8 to 11 The third aspect of this utility model provides a vehicle energy recovery device, including a hydraulic energy generation system as described in the second aspect, wherein a flange connection module 30 is fixedly connected to a wheel 81, and a mounting base 84 is fixedly mounted on a cylinder 10, and the mounting base 84 is hingedly connected to the vehicle suspension system.

[0071] In a specific application example, the vehicle's brake 83 is connected to the brake disc 82 and wheel 81 via a flange. The vehicle's brake 83 is mounted on the swing buffer frame 34. The mounting base 84 is locked and fixed to the cylinder block 10. The end of the mounting base 84 is provided with a hinge platform, which is hinged to the vehicle's suspension system.

[0072] In application, the wheel 81 is assembled with the flange connection module 30, and the cylinder 10 is hinged to the vehicle suspension system through the mounting base 84. When the weight of the vehicle body acts on the vehicle suspension system or when bumps occur, the wheel 81 and the vehicle suspension system are displaced. At this time, the cylinder 10 and the flange connection module 30 are deflected to form a swing angle, so that energy can be continuously recovered during vehicle driving, effectively improving the driving range.

[0073] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
