[0045] One end of the drive link 101 is connected to the vehicle vibration assembly 50, and the other end of the drive link 101 is connected to the end of the ratchet drive arm 102, and the ratchet included in the ratchet drive arm 102 is engaged with the transmission gear set 103.

[0046] When the vehicle vibration assembly 50 moves in the first direction, the driving link 101 drives the ratchet driving arm 102 to rotate, the ratchet driving arm 102 drives the transmission gear set 103 to rotate, the driving gear 1041 included in the generator 104 is engaged with the transmission gear set 103, the driving gear 1041 of the generator 104 rotates in the first rotation direction, and the generator 104 is in the power generation state.

[0047] When the vehicle vibration assembly 50 moves in the second direction, the driving link 101 drives the ratchet driving arm 102 to rotate, the ratchet driving arm 102 drives the transmission gear set 103 to rotate, the driving gear 1041 included in the generator 104 is in the disengaged state with the transmission gear set 103, and the driving gear 1041 of the generator 104 rotates in the first rotation direction under the action of inertia, wherein the first direction is the direction close to the ratchet driving arm 102, the second direction is the direction away from the ratchet driving arm 102, and the first rotation direction is the rotation direction of the driving gear 1041 of the generator 104 when the generator 104 is in the power generation state.

[0048] It should be noted that the vehicle energy storage device can include one mechanical energy conversion assembly 10 or multiple mechanical energy conversion assemblies 10, the number of mechanical energy conversion assemblies 10 and the number of vehicle vibration assemblies 50 and the power generation demand determine, and the embodiments of the present application do not limit this. Among them, the vehicle vibration assembly 50 can be a component that can vibrate the vehicle and a component that can produce relative displacement between the vehicle spring and the vehicle spring. For example, the vehicle vibration assembly 50 includes a suspension lower swing arm, a connecting component between the vehicle spring and the vehicle spring.

[0049] In addition, the end of the driving link 101 and the end of the ratchet driving arm 102 are hinged, the energy generated by the vehicle vibration assembly 50 is transmitted to the ratchet driving arm 102 through the driving link 101, and then transmitted to the transmission gear set 103 through the ratchet driving arm 102, and then transmitted to the generator 104 through the transmission gear set 103. As shown in Figure 5 The end of the driving link 101 and the end of the ratchet driving arm 102 are hinged, the energy generated by the vehicle vibration assembly 50 is transmitted to the ratchet driving arm 102 through the driving link 101, and then transmitted to the transmission gear set 103 through the ratchet driving arm 102, and then transmitted to the generator 104 through the transmission gear set 103. As shown in It should be noted that the vehicle energy storage device can include one mechanical energy conversion assembly 10 or multiple mechanical energy conversion assemblies 10, the number of mechanical energy conversion assemblies 10 and the number of vehicle vibration assemblies 50 and the power generation demand determine, and the embodiments of the present application do not limit this. Among them, the vehicle vibration assembly 50 can be a component that can vibrate the vehicle and a component that can produce relative displacement between the vehicle spring and the vehicle spring. For example, the vehicle vibration assembly 50 includes a suspension lower swing arm, a connecting component between the vehicle spring and the vehicle spring.

[0050] It should be noted that, when the vehicle vibration assembly 50 moves in the first direction, i.e. the vehicle vibration assembly 50 moves in the direction approaching the ratchet driving arm 102, the ratchet driving arm 102 rotates, i.e. rotates clockwise, and since the ratchet and the transmission gear set 103 are engaged, the ratchet driving arm 102 drives the transmission gear set 103 to rotate, and the driving gear 1041 of the generator 104 is driven by the transmission gear set 103 to rotate in the first rotation direction, and the generator 104 is in the power generation state. Conversely, when the vehicle vibration assembly 50 moves in the second direction, i.e. the vehicle vibration assembly 50 moves in the direction away from the ratchet driving arm 102, the ratchet driving arm 102 rotates, i.e. rotates counterclockwise, and since the ratchet and the transmission gear set 103 are engaged, the ratchet driving arm 102 drives the transmission gear set 103 to rotate, and the transmission gear set 103 and the generator 104 are separated, and the driving gear 1041 of the generator 104 rotates in the first rotation direction under the action of inertia, and the driving gear 1041 of the generator 104 is prevented from rotating in the reverse direction. Wherein, the movement of the vehicle vibration assembly 50 in the first direction and the movement of the vehicle vibration assembly 50 in the second direction can be understood as the longitudinal vibration of the vehicle vibration assembly 50, i.e. the vehicle vibration assembly 50 vibrates each time according to the above-mentioned energy conversion mode, so that the generator 104 can always generate electricity according to the vibration of the vehicle vibration assembly 50. Wherein, the first direction is the direction indicated by X1 in Figure 1 , the second direction is the direction indicated by X2 in Figure 2 , and the first rotation direction is the direction indicated by Z in Figure 1 .

[0051] As can be seen from the above embodiment, in the embodiment of the present application, the vehicle energy storage device comprises at least one mechanical energy conversion assembly 10, the mechanical energy conversion assembly 10 comprises a driving link 101, a ratchet driving arm 102 and a transmission gear set 103, and a generator 104, one end of the driving link 101 is connected with the vehicle vibration assembly 50, the other end of the driving link 101 is connected with the end of the ratchet driving arm 102, the ratchet driving arm 102 comprises a ratchet and the transmission gear set 103, and the ratchet and the transmission gear set 103 are engaged, so that the ratchet driving arm 102 rotates, i.e. rotates clockwise, when the vehicle vibration assembly 50 moves in the first direction, the transmission gear set 103 rotates under the action of the ratchet driving arm 102, and then the driving gear 1041 of the generator 104 and the transmission gear set 103 are engaged, the driving gear 1041 of the generator 104 rotates in the first rotation direction under the action of the transmission gear set, and then the generator 104 is in the power generation state. When the vehicle vibration assembly 50 moves in the first direction, the ratchet driving arm 102 rotates, i.e. rotates clockwise, the transmission gear set 103 rotates under the action of the ratchet driving arm 102, the driving gear 1041 of the generator 104 and the transmission gear set 103 are in the disengaged state, and the driving gear 1041 of the generator 104 rotates in the first rotation direction under the action of inertia. In this way, when the vehicle vibration assembly 50 moves in the first direction and the second direction once in a period, i.e. when the vehicle vibration assembly 50 longitudinally vibrates once, the generator 104 is in the power generation state, and then the vibration of the vehicle vibration assembly 50 can be used to generate power, the energy waste is avoided, the vibration energy is fully recovered, the structure of the entire vehicle energy storage device is relatively simple, and the cost of vibration energy recovery of the vehicle vibration assembly 50 is further reduced.

[0052] In order to complete the energy conversion and storage, in some embodiments, the vehicle energy storage device further comprises a rectifier 20, the rectifier 20 is connected with the output end of the generator 104, the output end of the generator 104 is connected with the rotor disc of the generator 104, and the rotor disc of the generator 104 is connected with the driving gear 1041 of the generator 104; a vehicle charger 30, the vehicle charger 30 is connected with the rectifier 20; and a power supply 40, the vehicle charger 30 is connected with the vehicle charger 30.

[0053] It should be noted that the rectifier 20 is a device for converting alternating current into direct current, that is, the alternating current generated by the generator 104 is converted into direct current after passing through the rectifier 20. Specifically, the rectifier 20 is connected to the output end of the generator 104, the output end of the generator 104 is connected to the rotor disc of the generator 104, the rotor disc of the generator 104 is connected to the driving gear 1041 of the generator 104, and thus the alternating current generated by the generator 104 can be converted into direct current after passing through the rectifier 20 under the condition that the driving gear 1041 of the generator 104 rotates. Since the vehicle-mounted charger 30 is connected to the rectifier 20, and the vehicle-mounted charger 30 is connected to the vehicle-mounted charger 30, the direct current converted by the vehicle-mounted charger 30 is input into the power supply 40 after being boosted again, and the entire energy conversion and storage is completed. As described above, as long as the vehicle is running, the additional power supply can be continuously supplemented, so that the endurance and economy of the vehicle are improved. In addition, it should be noted that when the vehicle energy storage device includes a plurality of mechanical energy conversion assemblies 10, the currents generated by the plurality of mechanical energy conversion assemblies 10 can be connected in parallel and simultaneously input into the rectifier 20 to complete the energy conversion of the plurality of mechanical energy conversion assemblies 10.

[0054] Next, the specific structure and connection relationship of the transmission gear set 103 included in the embodiment of the application will be specifically introduced as follows.

[0055] In some embodiments, the transmission gear set 103 includes a first double coupling gear 1031 and a second double coupling gear 1032; the first double coupling gear 1031 includes a first transmission gear 10311 and a second transmission gear 10312 coaxially rotating, wherein the pitch circle diameter of the first transmission gear 10311 is smaller than the pitch circle diameter of the second transmission gear 10312; the second double coupling gear 1032 includes a third transmission gear 10321 and a fourth transmission gear 10322 coaxially rotating, wherein the pitch circle diameter of the third transmission gear 10321 is smaller than the pitch circle diameter of the fourth transmission gear 10322; the first transmission gear 10311 and the ratchet included in the ratchet driving arm 102 are engaged, the second transmission gear 10312 and the third transmission gear 10321 are engaged, and the fourth transmission gear 10322 and the driving gear 1041 included in the generator 104 are engaged under the condition that the vehicle vibration assembly 50 moves in the first direction.

[0056] It should be noted that the first double gear 1031 and the second double gear 1032 are coaxial rotation structures of two transmission gears, that is, two transmission gears are arranged on one rotating shaft at the same time. Specifically, the first double gear 1031 includes a first transmission gear 10311 and a second transmission gear 10312 which rotate coaxially, and the second double gear 1032 includes a third transmission gear 10321 and a fourth transmission gear 10322 which rotate coaxially. Since the pitch circle diameter of the first transmission gear 10311 is smaller than the pitch circle diameter of the second transmission gear 10312, and the pitch circle diameter of the third transmission gear 10321 is smaller than the pitch circle diameter of the fourth transmission gear 10322, when the first transmission gear 10311 and the ratchet gear included in the ratchet drive arm 102 are engaged, and the second transmission gear 10312 and the third transmission gear 10321 are engaged, a plurality of transmission pairs can be established in the transverse direction, the rotational speed of the output shaft of the first double gear 1031 and the rotational speed of the second double gear 1032 are changed, and then the transmission ratio between the transmission gear set 103 is changed, and at the same time, the installation space in the radial direction of the first transmission gear 10311 can be saved. Since the fourth transmission gear 10322 and the driving gear 1041 included in the generator 104 are engaged when the vehicle vibration assembly 50 moves in the first direction, the energy transmission can be carried out through the multi-gear, which not only improves the transmission efficiency, but also improves the accuracy of the transmission ratio and the precision of the transmission, and improves the transmission power, and improves the compactness of the vehicle energy storage device structure.

[0057] It should be further noted that when the vehicle vibration assembly 50 moves in the first direction, the ratchet drive arm 102 rotates, and then drives the first transmission gear 10311 to rotate, since the first transmission gear 10311 and the second transmission gear 10312 rotate coaxially, and then the second transmission gear 10312 drives the third transmission gear 10321 to rotate, since the third transmission gear 10321 and the fourth transmission gear 10322 rotate coaxially, and then the fourth transmission gear 10322 and the driving gear 1041 included in the generator 104 are engaged, and then the generator 104 is driven to generate electricity. When the vehicle vibration assembly 50 moves in the second direction, the ratchet drive arm 102 rotates, and then drives the first transmission gear 10311 to rotate, since the first transmission gear 10311 and the second transmission gear 10312 rotate coaxially, and then the second transmission gear 10312 drives the third transmission gear 10321 to rotate, since the third transmission gear 10321 and the fourth transmission gear 10322 rotate coaxially, and then the fourth transmission gear 10322 and the driving gear 1041 included in the generator 104 are in a separated state, so that the generator 104 can rotate in the same direction.

[0058] Optionally, in some embodiments, the top circle diameter of the teeth of the second transmission gear 10312, the pitch circle diameter of the first transmission gear 10311, the pitch circle diameter of the fourth transmission gear 10322, and the pitch circle diameter of the third transmission gear 10321 form an arithmetic progression.

[0059] It should be noted that since the transmission ratio is equal to the value of the driving wheel speed divided by the driven wheel speed, or equal to the reciprocal of the pitch circle value of the gear, in the case where the top circle diameter of the teeth of the second transmission gear 10312, the pitch circle diameter of the first transmission gear 10311, the pitch circle diameter of the fourth transmission gear 10322, and the pitch circle diameter of the third transmission gear 10321 form an arithmetic progression, the top circle diameter of the teeth of the second transmission gear 10312, the pitch circle diameter of the first transmission gear 10311, the pitch circle diameter of the fourth transmission gear 10322, and the pitch circle diameter of the third transmission gear 10321 decrease in turn, and in turn, the transmission ratio between the first transmission gear 10311 and the ratchet included in the ratchet drive arm 102, the transmission ratio between the second transmission gear 10312 and the third transmission gear 10321, and the transmission ratio between the fourth transmission gear 10322 and the drive gear 1041 included in the generator 104 increase in turn, which is conducive to further improving the transmission efficiency of the vehicle energy storage device.

[0060] In order to make the structure of the vehicle energy storage device more compact, in some embodiments, as shown in Figure 3 and Figure 4 The vehicle energy storage device further comprises a mounting housing 60, the mounting housing 60 has a mounting inner cavity; the transmission gear set 103, the ratchet drive arm 102, and the generator 104 are mounted in the mounting inner cavity.

[0061] It should be noted that the mounting housing 60 can include a first housing and a second housing, both of which can be cavities, and the first housing and the second housing can be clamped, screwed, and welded to form a mounting cavity that can mount the transmission gear set 103, the ratchet drive arm 102, and the generator 104. In this way, the transmission gear set 103, the ratchet drive arm 102, and the generator 104 are mounted in the mounting inner cavity, and in turn, the structure of the vehicle energy storage device is more compact.

[0062] Further, the specific installation mode of the transmission gear set 103, the ratchet drive arm 102 and the generator 104 on the installation shell 60 is that the installation shell 60 is provided with a first fixed shaft sleeve 601, a second fixed shaft sleeve 602, a sliding shaft sleeve 603 and a fixed shaft hole 604; the ratchet drive arm 102 includes a first drive shaft, the first double gear 1031 includes a second drive shaft, the second double gear 1032 includes a third drive shaft, and the generator 104 includes a fourth drive shaft; the first drive shaft is installed in the first fixed shaft sleeve 601, the second drive shaft is installed in the second fixed shaft sleeve 602, the third drive shaft is movably connected in the sliding shaft sleeve 603, and the fourth drive shaft is installed in the fixed shaft hole 604.

[0063] It should be noted that, since the first drive shaft is installed in the first fixed shaft sleeve 601 and the second drive shaft is installed in the second fixed shaft sleeve 602, the rotating position of the first drive shaft of the ratchet drive arm 102 is located on the axis of the first fixed shaft sleeve 601, the rotating position of the first double gear 1031 is located on the axis of the first fixed shaft sleeve 601, the shaft distance between the first double gear 1031 and the second double gear 1032 remains unchanged, and thus the relative position of the first double gear 1031 and the second double gear 1032 remains fixed during rotation. Since the second double gear 1032 needs to be dynamically connected with the drive gear 1041 included in the generator 104, the third drive shaft included in the second double gear 1032 needs to be movably connected in the sliding shaft sleeve 603, thereby providing space for the change of the distance between the shaft center of the second double gear 1041 and the shaft center of the drive gear 1041 included in the generator 104, facilitating the dynamic connection between the second double gear 1032 and the drive gear 1041 included in the generator 104, and making the structure of the vehicle energy storage device more compact.

[0064] Further, in some embodiments, the sliding shaft sleeve 603 is a long circular hole structure; the sliding shaft sleeve 603 includes a first position and a second position, the first position is a position of the sliding shaft sleeve 603 close to the fixed shaft hole 604, and the second position is a position away from the fixed shaft hole 604; in the case that the drive gear 1041 included in the generator 104 and the fourth transmission gear 10322 are engaged, the fourth drive shaft is located at the first position, and in the case that the drive gear 1041 included in the generator 104 and the fourth transmission gear 10322 are separated, the fourth drive shaft is located at the second position.

[0065] It should be noted that, since the sliding sleeve 603 is a long hole structure, the fourth drive shaft can move along the extension direction of the sliding sleeve 603. In this way, when the vehicle vibration assembly 50 moves in the first direction, the ratchet drive arm 102 rotates, and the first transmission gear 10311 rotates, since the first transmission gear 10311 and the second transmission gear 10312 rotate coaxially, the second transmission gear 10312 drives the third transmission gear 10321 to rotate, since the third transmission gear 10321 and the fourth transmission gear 10322 rotate coaxially, the fourth drive shaft gradually moves to the first position, when the fourth drive shaft gradually moves to the first position, the driving gear 1041 included in the generator 104 and the fourth transmission gear 10322 are engaged, thereby driving the generator 104 to generate electricity. When the vehicle vibration assembly 50 moves in the second direction, the ratchet drive arm 102 rotates, and the first transmission gear 10311 rotates, since the first transmission gear 10311 and the second transmission gear 10312 rotate coaxially, the second transmission gear 10312 drives the third transmission gear 10321 to rotate, since the third transmission gear 10321 and the fourth transmission gear 10322 rotate coaxially, the fourth drive shaft gradually moves to the second position, when the fourth drive shaft gradually moves to the second position, the driving gear 1041 included in the generator 104 and the fourth transmission gear 10322 are in a separated state, thereby avoiding the generator 104 from reversing.

[0066] Optionally, in some embodiments, the vehicle energy storage device further comprises a return spring 70, one end of the return spring 70 is connected to the inner wall of the mounting shell 60, and the other end is connected to the ratchet drive arm 102; when the driving gear 1041 included in the generator 104 and the transmission gear set 103 are engaged, the return spring 70 is in an elongated state.

[0067] It should be noted that, since the return spring 70 is in an elongated state when the driving gear 1041 included in the generator 104 and the transmission gear set 103 are engaged, in this state, the vehicle vibration assembly 50 moves in the first direction. When the vehicle vibration assembly 50 moves in the second direction, the driving gear 1041 included in the generator 104 and the transmission gear set 103 can be quickly disengaged under the action of the restoring force of the return spring 70, thereby ensuring that when the vehicle vibration assembly 50 moves in the second direction, the generator 104 can be prevented from rotating in the opposite direction.

[0068] Further, the line between the axis of the first fixed sleeve 601 and the axis of the second fixed sleeve 602 is a first straight line, and the axis of the fixed shaft hole 604 is located on one side of the first straight line.

[0069] It should be noted that, since the line between the axis of the first fixed shaft sleeve 601 and the axis of the second fixed shaft sleeve 602 is a first straight line, and the axis of the fixed shaft hole 604 is located on one side of the first straight line, the driving gear 1041 of the generator 104 is located on one side of the line between the first driving shaft and the second driving shaft, thereby providing space for the change in the distance between the axis of the second double driving gear 1041 and the axis of the driving gear 1041 included in the generator 104.

[0070] As can be seen from the above embodiment, in the embodiment of the present application, since the vehicle energy storage device includes at least one mechanical energy conversion assembly 10, the mechanical energy conversion assembly 10 includes a driving link 101, a ratchet driving arm 102, a transmission gear set 103, and a generator 104, one end of the driving link 101 is connected to the vehicle vibration assembly 50, the other end of the driving link 101 is connected to the end of the ratchet driving arm 102, the ratchet included in the ratchet driving arm 102 is engaged with the transmission gear set 103, and thus in the case that the vehicle vibration assembly 50 moves in the first direction, the ratchet driving arm 102 rotates, i.e., rotates clockwise, the transmission gear set 103 rotates under the action of the ratchet driving arm 102, thereby causing the driving gear 1041 included in the generator 104 to engage with the transmission gear set 103, the driving gear 1041 of the generator 104 rotates in the first rotation direction under the action of the transmission gear set, thereby causing the generator 104 to be in a power generation state. In the case that the vehicle vibration assembly 50 moves in the first direction, the ratchet driving arm 102 rotates, i.e., rotates clockwise, the transmission gear set 103 rotates under the action of the ratchet driving arm 102, causing the driving gear 1041 included in the generator 104 to be in a disengaged state with the transmission gear set 103, the driving gear 1041 of the generator 104 rotates in the first rotation direction under the action of inertia. In this way, in the case that the vehicle vibration assembly 50 moves in the first direction and the second direction once in a period, i.e., in the case that the vehicle vibration assembly 50 vibrates longitudinally once, the generator 104 can be in a power generation state, thereby enabling the vehicle to generate power by using the vibration of the vehicle vibration assembly 50, further saving energy, and expanding the application scenarios of the vehicle.

[0071] The embodiment of the present application provides a vehicle including the vehicle energy storage device in the above embodiment. In this way, since the vehicle includes the vehicle energy storage device in the above embodiment, the vehicle energy storage device has the advantages of avoiding energy waste and fully recovering vibration energy, thereby enabling the vehicle to generate power by using the vibration of the vehicle vibration assembly 50, further saving energy, and expanding the application scenarios of the vehicle.

[0072] The above embodiments are only preferred embodiments of the present application for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the present application are within the protection scope of the present application.
