Background
In a suspension system of a vehicle, vibration is generated due to impact of an elastic element, and in order to improve running smoothness of the vehicle, a shock absorber is arranged in parallel with the elastic element in the suspension to attenuate the vibration. Among them, hydraulic shock absorbers are more common, and the working principle of the hydraulic shock absorbers is that when the relative motion occurs due to the vibration between a frame (or a vehicle body) and an axle, the piston in the shock absorber moves up and down, and the oil in the cavity of the shock absorber flows into the other cavity from one cavity through different holes repeatedly. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form damping force to vibration, so that the vibration energy of the automobile is converted into the heat energy of the oil, and then absorbed by the shock absorber and emitted into the atmosphere. However, the efficiency of the shock absorber for converting the vibration energy of the automobile into the oil heat energy is limited, so that the shock filtering efficiency of the shock absorber is difficult to be improved. In addition, even if the vehicle runs on the paved road in the city, a large amount of jolt still can be generated, the shock absorber absorbs and converts more vehicle vibration energy, and if the vehicle vibration capacity can be recovered, the energy utilization rate of the vehicle can be greatly improved.

Detailed Description
The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.
As shown in fig. 1 to 5, the swing arm type suspension vibration energy recovery device of the present invention is schematically shown, and comprises a first energy recovery assembly 1, an elastic force compensation assembly 3, a frame 4, a swing arm 5 and an electric storage device (not shown), wherein as shown in fig. 1, 2 and 5, the swing arm 5 is rotatably connected to the frame 4 through a rotating shaft 6, the frame 4 is preferably a chassis or a frame of a vehicle, and a wheel can be mounted at a swinging end of the swing arm 5. When the vehicle travels to a rough road surface, the swing arm 5 swings about the rotation shaft 6 with respect to the frame body 4.
As shown in fig. 4, the first energy recovery assembly 1 includes a first transmission shaft 11, a first speed increasing device 12, a first elastic member 14, and a first generator 13, and the electric storage device is electrically connected to the first generator 13. The output end of the first speed increasing device 12 is connected to the main shaft of the first generator 13, the input end of the first speed increasing device 12 is connected to the first transmission shaft 11, and the first speed increasing device 12 can increase the rotation speed of the first transmission shaft 11 to the rated power generation rotation speed of the first generator 13. The first transmission shaft 11 is connected to the rotating shaft 6 through a first one-way clutch device 111, when the swing arm 5 swings around the rotating shaft 6 forward relative to the frame 4, the first one-way clutch device 111 locks and allows the rotating shaft 6 to drive the first transmission shaft 11 to rotate, conversely, when the swing arm 5 swings around the rotating shaft 6 backward relative to the frame 4, the first one-way clutch device 111 unlocks and prohibits the rotating shaft 6 from driving the rotating shaft 11 to rotate (i.e. the rotating shaft 6 and the first transmission shaft 11 rotate relative to each other, and power cannot be transmitted to the first transmission shaft 11 from the rotating shaft 6), so as to ensure that the main shaft of the first generator 13 always runs stably towards the same rotation direction.
Further, two ends of the first elastic member 14 are respectively connected to the input ends of the first transmission shaft 11 and the first speed increasing device 12, and a third one-way clutch device 112 with a locking rotation direction opposite to that of the first one-way clutch device 111 is disposed on the first transmission shaft 11. When the swing arm 5 just begins to swing around the rotating shaft 6 relative to the frame body 4, the spindle rotation speed of the first generator 13 is gradually increased from zero, the first elastic piece 14 can relieve impact of severe swing of the swing arm 5 on the first generator 13, meanwhile, the first elastic piece 14 can temporarily store kinetic energy of the first transmission shaft 11, and when the spindle rotation speed of the first generator 13 is faster, the first elastic piece 14 can release the temporarily stored kinetic energy to the spindle of the first generator 13. The third one-way clutch device 112 is used for preventing the first transmission shaft 11 from reversely rotating under the elastic force of the first elastic member 14, so that the temporary stored kinetic energy of the first elastic member 14 is released by the first transmission shaft 11, and the kinetic energy is lost.
Preferably, the first speed increasing device 12 includes a first ring gear 121 fixed opposite to the first generator 13, a first sun gear 122 connected to an output end of the first speed increasing device 12, a first planet carrier 123 connected to the first transmission shaft 11, and a first planet 124 rotatably connected to the first planet carrier 123.
As shown in fig. 5, the elastic compensation component 3 is located on the frame body 4, the elastic compensation component 3 includes an actuator 31, and a first air bag 32 and a second air bag 33 which are communicated, the end of the second air bag 33 is abutted to the swing arm 5, and the actuator 31 can compress or stretch the first air bag 32. In the present embodiment, when the actuator 31 compresses the first air bag 32, the air flows from the first air bag 32 to the second air bag 33 and causes the second air bag 33 to expand, the expanded second air bag 33 pushes the swing arm 5, and the resistance of the swing arm 5 to the forward swing of the frame body 4 about the rotation shaft 6 increases (i.e., the expanded second air bag 33 prevents the swing arm 5 from the forward swing of the frame body 4); conversely, when the actuator 31 stretches the first air bag 32, the air flows from the second air bag 33 to the first air bag 32 and causes the second air bag 33 to contract, thereby reducing the resistance of the swing arm 5 to the forward swing of the frame body 4 about the rotation shaft 6. Since the charging currents of the electric storage device in different charging stages are different, for example, when the electric quantity of the electric storage device is small (the electric quantity is 0-80%), the required charging current is large, so that the internal resistance of the first generator 13 increases along with the increase of the charging current of the electric storage device, at this time, the increase of the internal resistance of the first generator 13 causes that a larger external force is required to enable the swing arm 5 to swing forward around the rotating shaft 6 relative to the frame 4, and passengers can feel that the bumping feeling of the vehicle is enhanced. For this purpose, the actuator 31 adjusts the first air bag 32 and makes the second air bag 33 to swing forward relative to the frame body 4, so as to compensate the compression resistance variation of the first energy recovery assembly 1, ensure the total compression resistance of the first energy recovery assembly 1 and the elastic force compensation assembly 3 to be within a preset constant value or a certain resistance range, and avoid the compression resistance variation of the energy recovery device along with the charging current variation of the electric storage device. During spring force compensation, the compression resistance of the device = the compression resistance of the first energy recovery module 1 + the compression resistance of the spring force compensation module 3.
In addition, the actuator 31 includes a driving motor 311, a screw rod 312, and a nut (not shown) connected to the driving motor 311, where the nut is movably connected to the screw rod 312 in a matching manner, one end of the screw rod 312 abuts against the first air bag 32, and the driving motor 311 drives the screw rod 312 to rotate so as to force the screw rod 312 to move along the axial direction thereof to stretch or compress the first air bag 32.
As shown in fig. 2 to 4, in order to recover the kinetic energy of the swing arm 5 swinging reversely relative to the frame 4 about the rotation shaft 6, the apparatus further includes a second energy recovery assembly 2.
The second energy recovery assembly 2 includes a second transmission shaft 21, a second speed increasing device 22, a second elastic member 24, and a second generator 23, and the electric storage device is electrically connected to the second generator 23. The output end of the second speed increasing device 22 is connected to the main shaft of the second generator 23, the input end is connected to the second transmission shaft 21, and the second speed increasing device 22 can increase the rotation speed of the second transmission shaft 21 to the rated power generation rotation speed of the second generator 23, similar to the first speed increasing device 12. The second transmission shaft 21 is connected to the rotating shaft 6 through a second one-way clutch device 211, the second transmission shaft 21 and the first transmission shaft 11 are respectively located at two ends of the rotating shaft 6, when the swing arm 5 swings around the rotating shaft 6 in the opposite direction relative to the frame 4, the second one-way clutch device 211 locks and allows the rotating shaft 6 to drive the second transmission shaft 21 to rotate, conversely, when the swing arm 5 swings around the rotating shaft 6 in the opposite direction relative to the frame 4, the second one-way clutch device 211 unlocks and prohibits the rotating shaft 6 from driving the second transmission shaft 21 to rotate (i.e. the rotating shaft 6 and the second transmission shaft 21 rotate relatively, and power cannot be transmitted to the second transmission shaft 21 by the rotating shaft 6), so as to ensure that the main shaft of the second generator 23 always runs stably towards the same rotation direction. Wherein the generated power of the second generator 23 is smaller than the generated power of the first generator 13. Preferably, the first transmission shaft 11, the second transmission shaft 21 and the rotation shaft 6 are coaxially arranged.
When the electric quantity of the electric storage device is small (the electric quantity is 0-80%), the required charging current is large, so that the internal resistance of the second generator 23 can be increased along with the increase of the charging current of the electric storage device, at this time, the increase of the internal resistance of the second generator 23 causes that larger external force is required to enable the swing arm 5 to swing reversely relative to the frame body 4 around the rotating shaft 6, namely, the resilience of the swing arm 5 is insufficient, the rebound speed is low, and the jolt feeling of passengers can be increased. Therefore, the actuator 31 adjusts the first air bag 32 and enables the second air bag 33 to push the swing arm 5 to swing reversely relative to the frame 4 so as to compensate the compression resistance change of the second energy recovery assembly 2, ensure the total compression resistance of the second energy recovery assembly 2 and the elastic force compensation assembly 3 to be within a preset constant value or a certain resistance value range, and avoid the compression resistance of the energy recovery device from changing along with the charging current change of the electric storage device.
Similar to the structure of the first elastic member 14, two ends of the second elastic member 24 are respectively connected to the input ends of the second transmission shaft 21 and the second speed increasing device 22, and a fourth one-way clutch device 212 with a locking rotation direction opposite to that of the second one-way clutch device 211 is arranged on the second transmission shaft 21. When the swing arm 5 just begins to swing around the rotating shaft 6 relative to the frame body 4, the spindle rotating speed of the second generator 23 is gradually increased from zero, the second elastic piece 24 can relieve impact of severe swing of the swing arm 5 on the second generator 23, meanwhile, the second elastic piece 24 can temporarily store kinetic energy of the second transmission shaft 21, and when the spindle rotating speed of the second generator 23 is faster, the second elastic piece 24 can release the temporarily stored kinetic energy to the spindle of the second generator 23. The fourth one-way clutch 212 is used for preventing the second transmission shaft 21 from reversely rotating under the elastic force of the second elastic member 24, so that the temporary stored kinetic energy of the second elastic member 24 is released by the second transmission shaft 21, and the kinetic energy is lost.
Preferably, the second speed increasing device 22 includes a second ring gear 221 fixed opposite to the second generator 23, a second sun gear 222 connected to an output end of the second speed increasing device 22, a second planet carrier 223 connected to the second transmission shaft 21, and a second planet gear 224 rotatably connected to the second planet carrier 223.
In summary, in the swing arm 5 type suspension vibration energy recovery device of the present invention, the frame 4 is rotationally connected with the swing arm 5, when the vehicle encounters jolt, the swing arm 5 swings forward relative to the frame 4 around the rotating shaft 6, the first one-way clutch device 111 locks and allows the rotating shaft 6 to drive the first transmission shaft 11 to rotate, the power of the first transmission shaft 11 is transmitted to the first generator 13 by the first speed increasing device 12, and the kinetic energy is converted into electric energy by the first generator 13; when the swing arm 5 swings reversely around the rotating shaft 6 relative to the frame body 4, the first one-way clutch device 111 unlocks and prohibits the rotating shaft 6 from driving the first transmission shaft 11 to rotate, so as to ensure that the main shaft of the first generator 13 always runs stably towards the same rotation direction; since the rotational resistance of the first generator 13 is not constant at different output powers, the actuator 31 of the elastic force compensation component 3 compresses or stretches the first air bag 32 to change the pushing force of the second air bag 33 on the swing arm 5, so as to compensate the change of the compression resistance of the first energy recovery component 1, and the total compression resistance of the energy recovery device is in a certain preset resistance value range.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
