[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Reference below Figure 1 An energy recovery device 100 according to an embodiment of the first aspect of the present invention is described.

[0032] like Figure 1 As shown, the energy recovery device 100 according to the first embodiment of the present invention includes: a conversion mechanism and a generator 30.

[0033] The conversion mechanism includes an input shaft 10 and an output shaft 20. The input shaft 10 is used to connect the reciprocating moving parts to be recovered energy. The output shaft 20 is arranged at intervals and transmission connected to the input shaft 10. The conversion mechanism is configured to drive the output shaft 20 to rotate in the same direction when the input shaft 10 rotates in different directions. The output shaft 20 is transmission connected to the motor shaft 31 of the generator 30, and the output shaft 20 and the motor shaft 31 are arranged at an angle.

[0034] Specifically, the input shaft 10 is used to connect the reciprocating moving part whose energy is to be recovered, wherein the reciprocating moving part refers to an object that has a motion form of moving back and forth on the same path. In the reciprocating motion, the reciprocating moving part vibrates, swings or moves periodically back and forth in one direction, thereby forming a periodic cyclic motion. The periodic cyclic motion of the reciprocating moving part can drive the input shaft 10 to rotate clockwise or counterclockwise.

[0035] It should be noted that transmission connection refers to connecting two or more parts together through a certain assembly method to achieve the transmission of force or power. Transmission connection can effectively transfer force or power from one part to another, so that the entire system can operate normally. The two parts of the transmission connection can be directly or indirectly connected, as long as the force transmission can be achieved.

[0036] In a specific example, for example Figure 1As shown, the output shaft 20 is arranged on the left side of the input shaft 10, and the output shaft 20 is transmission-connected with the input shaft 10. For example, when the reciprocating movable member drives the input shaft 10 to rotate clockwise, the input shaft 10 can drive the output shaft 20 to rotate clockwise, and when the reciprocating movable member drives the input shaft 10 to rotate counterclockwise, the input shaft 10 still drives the output shaft 20 to rotate clockwise. For another example, when the reciprocating movable member drives the input shaft 10 to rotate clockwise, the input shaft 10 can drive the output shaft 20 to rotate counterclockwise, and when the reciprocating movable member drives the input shaft 10 to rotate counterclockwise, the input shaft 10 still drives the output shaft 20 to rotate counterclockwise.

[0037] Therefore, no matter whether the reciprocating moving part drives the input shaft 10 to rotate clockwise or counterclockwise, the output shaft 20 can rotate in the same direction, so that the energy recovery device 100 can continuously collect energy under the drive of the reciprocating moving part. In other words, the energy recovery device 100 can convert the mechanical energy generated by the reciprocating motion of the reciprocating moving part into the kinetic energy of the bidirectional rotation of the input shaft 10, and then further convert it into the unidirectional and stable rotation kinetic energy of the output shaft 20.

[0038] For example Figure 1 As shown, the output shaft 20 is drivingly connected to the motor shaft 31 of the generator 30, so that the generator 30 can effectively convert the unidirectional and smooth rotational kinetic energy of the output shaft 20 into electrical energy. That is to say, the energy recovery device 100 can effectively convert the mechanical energy generated by the reciprocating motion of the reciprocating parts into the unidirectional and smooth rotational kinetic energy of the output shaft 20, thereby effectively driving the generator 30 to generate electricity.

[0039] Furthermore, there is an angle between the axial direction of the output shaft 20 and the axial direction of the motor shaft 31. For example, the angle between the axial direction of the output shaft 20 and the axial direction of the motor shaft 31 can be 75°, 80°, 85°, 90°, 95° and 100°. In other words, considering the limited layout space, the path of energy transfer from the output shaft 20 to the motor shaft 31 is not a straight line, so that the energy recovery device 100 can be flexibly arranged according to requirements, thereby effectively optimizing the layout space. In addition, when it is necessary to increase the distance between the reciprocating moving part and the input shaft 10, the installation space can be effectively saved by arranging the output shaft 20 and the motor shaft 31 at an angle, thereby effectively increasing the length of the force arm of the energy recovery device 100, thereby effectively improving the energy conversion efficiency.

[0040] In this embodiment, when the reciprocating moving part reciprocates, the reciprocating moving part can drive the input shaft 10 to rotate clockwise or counterclockwise, the input shaft 10 can drive the output shaft 20 to rotate unidirectionally, the output shaft 20 can drive the motor shaft 31 to rotate unidirectionally and the energy transfer path from the output shaft 20 to the motor shaft 31 is not a straight line, so that the generator 30 can be continuously driven to generate electricity. Therefore, the energy recovery device 100 can effectively convert the mechanical energy generated by the reciprocating motion of the reciprocating moving part into the unidirectional and smooth rotational kinetic energy of the output shaft 20, thereby effectively driving the generator 30 to generate electricity.

[0041] According to the energy recovery device 100 of the embodiment of the present invention, a conversion mechanism and a generator 30 are set. The conversion mechanism includes an input shaft 10 and an output shaft 20. The input shaft 10 is used to connect the reciprocating moving parts of the energy to be recovered. The output shaft 20 is arranged at intervals and transmission connected to the input shaft 10. The conversion mechanism is configured to drive the output shaft 20 to rotate in the same direction when the input shaft 10 rotates in different directions. The output shaft 20 is transmission connected to the motor shaft 31 of the generator 30, and the output shaft 20 and the motor shaft 31 are arranged at an angle. Not only can the reciprocating activity be converted into unidirectional rotation, thereby continuously driving the generator 30 to generate electricity and realize energy recovery, but it can also effectively optimize the layout space of the energy recovery device 100, thereby effectively increasing the length of the force arm of the energy recovery device 100, and thereby effectively improving the conversion efficiency of the conversion mechanism.

[0042] In one embodiment of the present invention, the energy recovery device 100 further includes: an energy storage device and a rectifier. The energy storage device is connected to the generator 30 and is used to store the electric energy generated by the generator 30; the rectifier is connected between the generator 30 and the energy storage device.

[0043] Specifically, the energy storage device is an energy storage device having a charge and discharge function, and can be used to store the electric energy generated by the generator 30 and release the stored electric energy when needed. Furthermore, the energy storage device can be a supercapacitor.

[0044] The rectifier is a device that converts the AC power generated by the generator 30 into DC power. The rectifier converts the AC power generated by the generator 30 into DC power, supplies the power to the load after filtering, or inputs the power to the energy storage device to provide a charging voltage for the energy storage device, thus playing the role of a charger.

[0045] For example, the rectifier is connected between the generator 30 and the energy storage device, one end of the rectifier is connected to the generator 30, and the other end of the rectifier is connected to the energy storage device. When the generator 30 is working, the alternating current generated by the generator 30 is input into the rectifier, and the rectifier converts the alternating current into stable direct current after processing, and inputs it into the energy storage device for energy storage.

[0046] Therefore, by providing an energy storage device and a rectifier in the energy recovery device 100, the alternating current generated by the generator 30 can be converted into stable direct current, thereby providing a stable charging voltage, and then storing the electric energy for the operation of the electric drive system or other electronic equipment. At the same time, the rectifier can effectively protect the energy storage device, thereby extending the service life of the energy storage device.

[0047] In one embodiment of the present invention, Figure 1 As shown, the output shaft 20 is arranged perpendicular to the motor shaft 31. For example, the axial direction of the output shaft 20 is perpendicular to the axial direction of the motor shaft 31, so that a stable support structure can be formed between the output shaft 20 and the motor shaft 31, thereby effectively reducing vibration, thereby effectively ensuring the stability of the energy recovery device 100.

[0048] This embodiment can effectively ensure the stability and reliability of the energy recovery device 100 by arranging the output shaft 20 and the motor shaft 31 vertically. In addition, it can also effectively reduce the difficulty of installing the energy recovery device 100 and improve the convenience of installing the energy recovery device 100.

[0049] In one embodiment of the present invention, Figure 1 As shown, the energy recovery device 100 further includes a transmission mechanism 40 , which includes a first bevel gear 41 and a second bevel gear 42 that are meshed and driven. The first bevel gear 41 is sleeved on the output shaft 20 , and the second bevel gear 42 is sleeved and fixed on the motor shaft 31 .

[0050] In a specific example, if Figure 1 As shown, the first bevel gear 41 is fixed to the rear end of the output shaft 20 and serves as a driving gear, and the second bevel gear 42 is fixed to the right end of the motor shaft 31 and serves as a driven gear. When the output shaft 20 rotates unidirectionally, it can drive the first bevel gear 41 to rotate unidirectionally, the first bevel gear 41 can drive the second bevel gear 42 to rotate unidirectionally and change the energy transmission path, and the second bevel gear 42 can drive the motor shaft 31 to rotate unidirectionally, thereby continuously driving the generator 30 to generate electricity.

[0051] In this embodiment, a transmission mechanism 40 is set in the energy recovery device 100. The transmission mechanism 40 includes a first bevel gear 41 and a second bevel gear 42 for meshing transmission. The first bevel gear 41 is sleeved on the output shaft 20, and the second bevel gear 42 is sleeved on and fixed on the motor shaft 31. It can not only effectively transmit energy and change the energy transmission path, but also effectively ensure the smooth operation of the transmission mechanism 40, thereby effectively reducing noise and vibration.

[0052] In one embodiment of the present invention, Figure 1As shown, the two axial ends of the output shaft 20 are respectively an input end and an output end, the first bevel gear 41 is sleeved on the output end, and the second bevel gear 42 is arranged on the side of the first bevel gear 41 facing the input end.

[0053] In a specific example, if Figure 1 As shown, the front end of the output shaft 20 in the axial direction is the input end, the rear end of the output shaft 20 in the axial direction is the output end, the first bevel gear 41 is sleeved on the output end, and the small end of the first bevel gear 41 is located in front of the large end, the second bevel gear 42 is arranged on the left side of the first bevel gear 41, the second bevel gear 42 is meshed with the first bevel gear 41, and the second bevel gear 42 is located on the left side of the output shaft 20, and the small end of the second bevel gear 42 is located on the right side of the large end. Thus, the generator 30 can be set on the left side of the conversion mechanism.

[0054] In this embodiment, by sleeve-arranging the first bevel gear 41 on the output end and arranging the second bevel gear 42 on the side of the first bevel gear 41 facing the input end, the structural structure of the energy recovery device 100 can be further optimized, thereby further optimizing the layout space of the energy recovery device 100, reducing the installation space occupied by the energy recovery device 100, and effectively improving the compactness of the energy recovery device 100.

[0055] In one embodiment of the present invention, Figure 1 As shown, the number of teeth of the first bevel gear 41 is greater than the number of teeth of the second bevel gear 42. When the first bevel gear 41 drives the second bevel gear 42 to rotate, since the first bevel gear 41 and the second bevel gear 42 are directly meshed, the linear speed of the first bevel gear 41 and the linear speed of the second bevel gear 42 are the same, and because the number of teeth of the first bevel gear 41 is greater than the number of teeth of the second bevel gear 42, the angular speed of the second bevel gear 42 is greater than the angular speed of the first bevel gear 41, so that the low-speed rotation of the first bevel gear 41 can be converted into the high-speed rotation of the second bevel gear 42, so that the effect of increasing speed and reducing torque can be effectively achieved.

[0056] Furthermore, since the first bevel gear 41 rotates at a relatively low speed and bears a relatively high torque, a material with relatively high strength and good wear resistance, such as alloy steel or cast iron, can be selected for the first bevel gear 41. Since the second bevel gear 42 rotates at a relatively high speed and bears a relatively low torque, a material with relatively high hardness can be selected for the second bevel gear 42, and the surface of the second bevel gear 42 can be heat treated and hardened to ensure its wear resistance and life.

[0057] In this embodiment, the number of teeth of the first bevel gear 41 is set to be greater than the number of teeth of the second bevel gear 42, which can effectively achieve the effect of increasing speed and reducing torque, thereby effectively meeting the speed requirement of the motor shaft 31 of the generator 30, and further effectively improving the speed and power generation efficiency of the motor shaft 31 of the generator 30, thereby effectively protecting the generator 30 and extending the service life of the generator 30.

[0058] In one embodiment of the present invention, Figure 1 As shown, the energy recovery device 100 further includes: a housing 50, the housing 50 has a receiving cavity, the conversion mechanism and the transmission mechanism 40 are both arranged in the receiving cavity, the generator 30 is arranged outside the housing 50, and the motor shaft 31 extends into the receiving cavity. For example, the input shaft 10, the output shaft 20, the first bevel gear 41 and the second bevel gear 42 are all arranged in the installation cavity of the housing 50. Further, the housing 50 can be in the shape of a cuboid. Preferably, the housing 50 can be made of aluminum alloy.

[0059] In a specific example, if Figure 1 As shown, the generator 30 is arranged on the left side of the shell 50. Furthermore, a first through hole is provided on the front side surface of the shell 50, and a second through hole is provided on the left side surface of the shell 50. The left end of the input shaft 10 extends through the first through hole to the outside of the shell 50 to connect the reciprocating moving parts, and the motor shaft 31 of the generator 30 extends through the second through hole into the accommodating cavity to connect the second bevel gear 42.

[0060] In this embodiment, a housing 50 is provided in the energy recovery device 100, and a housing 50 has a housing cavity, in which the conversion mechanism and the transmission mechanism 40 are both provided, the generator 30 is arranged outside the housing 50, and the motor shaft 31 extends into the housing cavity, which can not only effectively protect the conversion mechanism and the transmission mechanism 40, but also play a role in sealing and dustproofing. In addition, the housing 50 can also provide a support for the motor shaft 31, thereby ensuring the normal operation of the motor shaft 31.

[0061] In one embodiment of the present invention, Figure 1 As shown, the input shaft 10 is provided with a first one-way bearing 11 and a second one-way bearing 12 arranged at intervals, and the relative rotation direction of the outer ring and the inner ring of the first one-way bearing 11 is opposite to the relative rotation direction of the outer ring and the inner ring of the second one-way bearing 12, and the output shaft 20 is sleeved with a first output gear and a second output gear 21 arranged at intervals, wherein the first output gear is transmission-connected to the outer ring of the first one-way bearing 11, and the second output gear 21 is transmission-connected to the outer ring of the second one-way bearing 12, and the rotation direction of the first one-way bearing 11 when driving the output shaft 20 to rotate through the first output gear is the same as the rotation direction of the second one-way bearing 12 when driving the output shaft 20 to rotate through the second output gear 21.

[0062] It should be noted that the first one-way bearing 11 and the second one-way bearing 12 are both one-way bearings, which are a type of bearing that can rotate freely in one direction and is locked in another direction. Figure 1 As shown, the first one-way bearing 11 and the second one-way bearing 12 are arranged on the input shaft 10 at intervals, the first one-way bearing 11 is located on the front side, the second one-way bearing 12 is located on the rear side, and the first one-way bearing 11 and the second one-way bearing 12 are installed opposite to each other on the input shaft 10.

[0063] Specifically, the inner ring of the first one-way bearing 11 can rotate counterclockwise relative to the outer ring, but cannot rotate clockwise relative to the outer ring, and the inner ring of the second one-way bearing 12 can rotate clockwise relative to the outer ring, but cannot rotate counterclockwise relative to the outer ring. Further, a first gear 111 is provided on the outer ring of the first one-way bearing 11, and a second gear 121 is provided on the outer ring of the second one-way bearing 12.

[0064] For example Figure 1 As shown, the first output gear and the second output gear 21 are arranged on the output shaft 20 at intervals, the first output gear is located at the front side, and the second output gear 21 is located at the rear side.

[0065] Furthermore, a first transmission member 60 is also provided in the energy recovery device 100, and the first transmission member 60 includes: an intermediate shaft 61, a first intermediate gear 62 and a second intermediate gear 63. The intermediate shaft 61 is parallel to the input shaft 10 and the output shaft 20 and is arranged at intervals. The first intermediate gear 62 and the second intermediate gear 63 are coaxially fixed on the intermediate shaft 61. The first intermediate gear 62 is meshed with the first gear 111, the second intermediate gear 63 is meshed with the first output gear, and the second output gear 21 is meshed with the second gear 121.

[0066] For example, when the input shaft 10 rotates clockwise under the drive of the reciprocating movable part, the input shaft 10 drives the inner ring of the first one-way bearing 11 to rotate clockwise. Since the inner ring of the first one-way bearing 11 is locked in the clockwise direction relative to the outer ring, the first gear 111 on the outer ring of the first one-way bearing 11 rotates clockwise together with the inner ring. Then, the first gear 111 drives the first intermediate gear 62 to rotate, the first intermediate gear 62 drives the intermediate shaft 61 to rotate, the intermediate shaft 61 drives the second intermediate gear 63 to rotate, the second intermediate gear 63 drives the first output gear to rotate, the first output gear drives the output shaft 20 to rotate, the output shaft 20 drives the first bevel gear 41 to rotate, the first bevel gear 41 drives the second bevel gear 42 to rotate, the second bevel gear 42 drives the motor shaft 31 to rotate and finally drives the generator 30 to generate electricity.

[0067] For another example, when the input shaft 10 rotates counterclockwise under the drive of the reciprocating movable part, the input shaft 10 drives the inner ring of the second one-way bearing 12 to rotate counterclockwise. Since the inner ring of the second one-way bearing 12 is locked counterclockwise relative to the outer ring, the second gear 121 on the outer ring of the second one-way bearing 12 rotates counterclockwise together with the inner ring. Then, the second gear 121 drives the second output gear 21 to rotate, the second output gear 21 drives the output shaft 20 to rotate, the output shaft 20 drives the first bevel gear 41 to rotate, the first bevel gear 41 drives the second bevel gear 42 to rotate, the second bevel gear 42 drives the motor shaft 31 to rotate and finally drives the generator 30 to generate electricity.

[0068] In this embodiment, a first one-way bearing 11 and a second one-way bearing 12 are arranged at intervals on the input shaft 10, and the relative rotatable direction of the outer ring and the inner ring of the first one-way bearing 11 is opposite to the relative rotatable direction of the outer ring and the inner ring of the second one-way bearing 12. The output shaft 20 is sleeved with a first output gear and a second output gear 21 arranged at intervals, wherein the first output gear is transmission-connected to the outer ring of the first one-way bearing 11, and the second output gear 21 is transmission-connected to the outer ring of the second one-way bearing 12, and the rotation direction of the output shaft 20 driven by the first one-way bearing 11 through the first output gear is the same as the rotation direction of the output shaft 20 driven by the second one-way bearing 12 through the second output gear 21, so that the input shaft 10 can be converted into a unidirectional and smooth rotational motion of the output shaft 20 regardless of whether it is a clockwise or counterclockwise rotational motion, thereby effectively driving the motor shaft 31 to rotate unidirectionally, and then driving the generator 30 to generate electricity continuously.

[0069] In one embodiment of the present invention, Figure 1 As shown, the energy recovery device 100 further includes: a connecting rod and a swing arm.

[0070] One end of the connecting rod is suitable for connecting to a reciprocating movable part. The swing arm extends radially along the input shaft 10 and has a first end and a second end. The first end is hinged to the other end of the connecting rod, and the second end is fixedly connected to the input shaft 10.

[0071] Specifically, a first ball joint is provided at one end of the connecting rod, and the connecting rod is connected to the reciprocating member through the first ball joint, and a second ball joint is provided at the other end of the connecting rod and connected to the first end of the swing arm through the second ball joint, and the second end of the swing arm is fixedly connected to the input shaft 10. When the reciprocating member moves, the reciprocating member drives the connecting rod to reciprocate, the connecting rod drives the swing arm to rotate clockwise or counterclockwise around the input shaft 10, and the swing arm drives the input shaft 10 to rotate clockwise or counterclockwise.

[0072] In this embodiment, a connecting rod and a swing arm are arranged in the energy recovery device 100. One end of the connecting rod is suitable for connecting a reciprocating moving part. The swing arm extends radially along the input shaft 10 and has a first end and a second end. The first end is hinged to the other end of the connecting rod, and the second end is fixedly connected to the input shaft 10. This enables the mechanical energy generated by the reciprocating moving part to be effectively converted into the rotational kinetic energy of the swing arm's bidirectional fixed-axis rotation, and then transmitted to the input shaft 10 of the conversion mechanism and converted into the unidirectional and stable rotational kinetic energy of the input shaft 10, thereby finally realizing the effective conversion of energy forms.

[0073] The vehicle according to the second embodiment of the present invention comprises a suspension 700 and an energy recovery device 100 according to the first embodiment of the present invention.

[0074] The input shaft 10 is connected to the suspension 700, and one of the axial directions of the output shaft 20 and the motor shaft 31 is the front-rear direction of the vehicle and the other is the left-right direction of the vehicle. For example, the axial direction of the output shaft 20 is the front-rear direction of the vehicle, and the axial direction of the motor shaft 31 is the left-right direction of the vehicle; for another example, the axial direction of the output shaft 20 is the left-right direction of the vehicle, and the axial direction of the motor shaft 31 is the front-rear direction of the vehicle.

[0075] Furthermore, the vehicle further includes a body and a wheel 80 assembly, and the suspension 700 is connected between the body and the wheel 80 assembly. The wheel 80 assembly is provided with a wheel 80, and the wheel 80 is in direct contact with the ground. When the vehicle is running, the bounce of the wheel 80 in the up-and-down direction can drive the suspension 700 to vibrate in the up-and-down direction.

[0076] In a specific example, if Figure 2 As shown, the axial direction of the output shaft 20 is the front-rear direction of the vehicle, and the axial direction of the motor shaft 31 is the left-right direction of the vehicle. When the suspension 700 of the vehicle vibrates up and down, the suspension 700 can drive the input shaft 10 to rotate clockwise or counterclockwise, the input shaft 10 can drive the output shaft 20 to rotate unidirectionally, and the output shaft 20 can drive the motor shaft 31 to rotate, thereby driving the generator 30 to continuously generate electricity.

[0077] The vehicle according to the embodiment of the present invention, by providing the energy recovery device 100 of the first embodiment mentioned above, can not only convert the reciprocating activity into a unidirectional rotation, thereby continuously driving the generator 30 to generate electricity and realize energy recovery, but also effectively optimize the layout space of the energy recovery device 100, thereby effectively increasing the length of the force arm of the energy recovery device 100, and further effectively improving the conversion efficiency of the conversion mechanism.

[0078] In one embodiment of the present invention, Figure 2As shown, the energy recovery device 100 is fixed on the rear sub-frame 70, and the number of the energy recovery devices 100 is two, and the two energy recovery devices 100 are symmetrically arranged on the left and right sides of the rear sub-frame 70. For example, the energy recovery device 100 can be fixed on the left and right sides of the rear sub-frame 70 by bolts, and further, one energy recovery device 100 is arranged on the left side of the rear end of the rear sub-frame 70 of the suspension 700, and the other energy recovery device 100 is arranged on the right side of the rear end of the rear sub-frame 70 of the suspension 700.

[0079] When the vehicle is running, the energy recovery devices 100 on the left and right sides of the rear subframe 70 of the suspension 700 can convert the mechanical energy generated by the up and down vibration of the suspension 700 into electrical energy, thereby more efficiently converting the energy of the suspension 700. In addition, the bilaterally symmetrical arrangement of the two energy recovery devices 100 can effectively simplify the installation process and effectively increase the installation speed.

[0080] In this embodiment, the energy recovery device 100 is fixed on the rear sub-frame 70. There are two energy recovery devices 100, which are symmetrically arranged on the left and right sides of the rear sub-frame 70, which can not only effectively improve the power generation efficiency of the energy recovery device 100, but also effectively improve the installation efficiency of the energy recovery device 100.
