[0002] As the world's energy and environmental protection issues are increasingly concerned, new energy vehicles have emerged. New energy vehicles are vehicles that use non-traditional fuels as power sources or use new power devices, including pure electric vehicles, hybrid vehicles, hydrogen fuel vehicles and other energy vehicles. Vigorously developing new energy vehicles, replacing oil with electricity, and reducing emissions are not only in line with my country's national conditions, but also represent the direction of the development of the world's automobile industry. Accelerating the industrialization of electric vehicles can not only promote energy conservation and emission reduction in the transportation field and the sustainable development of the automobile industry, but also promote the development of the automobile industry.

[0003] New energy vehicles basically use power batteries to provide energy for the drive motors. At present, the energy density of power batteries is not high enough, so the cruising range of new energy vehicles will be limited to a certain bottleneck. We found that the vehicle body is constantly vibrating up and down during driving. If this part of the vibration energy can be recycled, it will definitely increase the cruising range of new energy vehicles. Therefore, a vibration bidirectional energy feeding transmission device for new energy vehicles is needed to feed back the vibration energy to the power battery through the generator for real-time charging, thereby increasing the cruising range of new energy vehicles.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0022] Example

[0023] A vibration bidirectional energy feeding transmission device for new energy vehicles, comprising the following parts (see Figure 1 — Figure 4 ): the first tie rod 1 and the second tie rod 8, the first tie rod rack 2 and the second tie rod rack 9, the first input gear shaft 3 and the second input gear shaft 10, the first one-way clutch 4 and the second one-way clutch 11, the first speed-increasing gear 5 and the second speed-increasing gear 12, the first tie rod sliding bearing 6 and the second tie rod sliding bearing 13, the output gear shaft 14, the output gear shaft needle bearing 15, the tie rod outer shell 16, the first output gear shaft needle bearing 7 and the second output gear shaft needle bearing 21, the universal joint 18, the generator input shaft 19 and the generator 20.

[0024] The upper ends of the first tie rod 1 and the second tie rod 8 are connected to the vehicle body through hinges, and the tie rod outer shell 16 and the gear box shell 17 form the shell of this device, and the shell of this device is connected to the axle through hinges.

[0025] Figure 2The first tie rod rack 2 and the second tie rod rack 9 are respectively fixed to the first tie rod 1 and the second tie rod 8 by bolts and interference fit. This design can reduce the processing cost of the tie rod. The first tie rod sliding bearing 6 and the second tie rod sliding bearing 13 are respectively installed on the bearing seat of the tie rod outer shell 16, and the two ends of the first output gear shaft needle bearing 7 and the second output gear shaft needle bearing 21 are respectively installed on the bearing seats of the tie rod outer shell 16 and the gear box shell 17. The two ends of the output gear shaft needle bearing 15 of the output gear shaft 14 are also installed on the bearing seats of the tie rod outer shell 16 and the gear box shell 17. One end of the universal joint 18 is connected to the output gear shaft 14, and the other end is connected to the generator input shaft 19. The universal joint 19 can ensure the universal transmission of power between the output gear shaft 14 and the generator input shaft.

[0026] Figure 2 The first input gear shaft 3 is inserted into the inner race of the wedge-type first one-way clutch 4, and the outer race of the first one-way clutch 4 is integrated with the first speed-increasing gear 5. The one-way clutch allows the first input gear shaft 3 to transmit power in only one direction, and the other rotation direction is idle. Figure 2 It is shown that the first input gear shaft 3 can drive the speed increasing gear 5 to rotate counterclockwise. When the first input gear rotates clockwise, the one-way clutch 4 idles, so that the power cannot be transmitted to the first speed increasing gear 5, and the one-way power is interrupted.

[0027] Equivalently, Figure 2 The second input gear shaft 10 is inserted into the inner race of the second wedge-type one-way clutch 11, and the outer race of the second one-way clutch 11 is integrated with the second speed-increasing gear 12. The one-way clutch allows the second input gear shaft 10 to transmit power in only one direction, and the other rotation direction is idle. Figure 2 It is shown that the second output gear can drive the second speed-increasing gear 12 to rotate counterclockwise. When the second output gear rotates clockwise, the second one-way clutch 11 idles, so that the power cannot be transmitted to the second speed-increasing gear 12, and the one-way power is interrupted.

[0028] When the new energy vehicle encounters an uneven road surface, a pit or a bump, the vehicle will vibrate up and down in both directions, and the vehicle body will reciprocate up and down in both directions relative to the axle. This two-way up and down vibration will cause the first tie rod 1 and the second tie rod 8 to reciprocate up and down in both directions relative to the housing. This reciprocating motion can drive the first input gear and the second output gear in the gearbox, and transmit power to the output gear 14 through the first one-way clutch 4 and the second one-way clutch 11, and then through the first speed-increasing gear 5 and the second speed-increasing gear 12, so that the output gear 14 rotates continuously, driving the generator to rotate, and finally realizing two-way vibration energy recovery.

[0029] The device of the present invention can transmit the energy generated by the up and down bidirectional vibration of the vehicle body when the vehicle is on a bumpy road to the generator input shaft through the output gear and the universal joint, and convert it into battery energy through the generator, thereby realizing the recovery of the bidirectional vibration energy of the vehicle body. The device of the present invention can save energy and further improve the vehicle's cruising range.

[0030] Case 1: When the new energy vehicle passes through a bumpy road, the body of the vehicle generates a compression movement relative to the axle, and the body compresses the first tie rod 1 to move downward relative to the housing composed of the tie rod outer housing 16 and the gear box housing 17, and the first tie rod 1 drives the first tie rod rack 2 to move downward, and the first input gear shaft 3 matched with the first tie rod rack 2 is driven by the rack to rotate counterclockwise ( Figure 2 The first input gear shaft 3 is inserted into the inner race of the first wedge-type one-way clutch 4, and the outer race of the first one-way clutch 4 is integrated with the first speed-increasing gear 5. The first input gear shaft 3 can only transmit power to the first speed-increasing gear 5 in a counterclockwise direction through the first one-way clutch 4. Figure 2 As shown, when the vehicle body compresses the first tie rod 1, the first input gear shaft 3 can drive the first speed increasing gear 5 to rotate counterclockwise, thereby driving the output gear 14 to rotate clockwise. The output gear shaft 14 then transmits the power to the generator input shaft 19 through the universal joint 18, so that the generator 20 generates an electromotive force to charge the battery, thereby realizing energy recovery when the vehicle is pressed down during bumps.

[0031] At the same time, the vehicle body compresses the second tie rod 8 and moves downward relative to the housing composed of the tie rod outer housing 16 and the gear box housing 17. The second tie rod 8 drives the second tie rod rack 9 to move downward, and the second input gear shaft 10 matched with the second tie rod rack 9 is driven by the rack to generate instantaneous clockwise rotation ( Figure 2 The second input gear shaft 10 is inserted into the inner race of the wedge-type second one-way clutch 11, and the outer race of the second one-way clutch 11 is integrated with the second speed-increasing gear 12. Due to the clockwise idling effect of the second one-way clutch 11, the second input gear shaft 10 cannot drive the second speed-increasing gear 12 to rotate, and the second output gear shaft 10 idles.

[0032] Case 2: When the new energy vehicle passes through a bumpy road, the body of the vehicle stretches relative to the axle, and the body stretches the first tie rod 1 to move upward relative to the housing. The first tie rod 1 drives the first tie rod rack 2 to move upward, and the first input gear shaft 3 matched with the first tie rod rack 2 is driven by the rack to rotate clockwise ( Figure 2 As shown in the direction, due to the clockwise idling effect of the first one-way clutch 4, the first input gear shaft 3 cannot drive the first speed increasing gear 5 to rotate, and the first input gear shaft 3 idles and does not transmit power.

[0033] At the same time, the body stretches the second tie rod 8 to move upward relative to the housing, and the second tie rod 8 drives the second tie rod rack 9 to move upward, and the second input gear shaft 10 matched with the second tie rod rack 9 is driven by the rack to rotate counterclockwise ( Figure 2 The second input gear shaft 10 is inserted into the inner race of the second sprag-type one-way clutch 11, and the outer race of the second one-way clutch 11 is integrated with the second speed-increasing gear 12. The second one-way clutch 11 allows the input second input gear shaft 10 to transmit power to the second speed-increasing gear 12 in a counterclockwise direction. Figure 2 As shown, when the vehicle body stretches the second pull rod 8, the second input gear shaft 10 can drive the second speed increasing gear 12 to rotate counterclockwise, and drive the output gear shaft 14 to rotate clockwise. The output gear shaft 14 then transmits the power to the generator input shaft 19 through the universal joint 18, so that the generator 20 generates an electromotive force to charge the battery, thereby realizing energy recovery when the vehicle is stretched during bumps.
