Component 3 can perform reverse movements simultaneously.

Please refer to FIGS. 5 and 6 , the first power source 5 is used to drive the first rear wheel 12 to rotate, and the second power source 6 is used to drive the second rear wheel 13 to rotate. In this embodiment, the first power source 5 may have a motor 51 and a gearbox 52 (the gear is omitted in FIG. 5 ) installed at the rear end of the frame 11 , and the gearbox 52 is connected to the motor 51 And a power shaft 53, the power shaft 53 is combined with a front sprocket 54, a chain 55 is sleeved on the front sprocket 54 and a rear sprocket 56, the rear sprocket 56 is combined with the first rear wheel 12. In this way, the motor 51 can drive the power shaft 53 to rotate through the gearbox 52, thereby linking the rear sprocket 56 through the front sprocket 54 and the chain 55, causing the first rear wheel 12 to rotate; that is, the motor 51 can directly control the rotation speed of the first rear wheel 12.

The second power source 6 can have the same structure as the first power source 5 , so there is no differential between the motor 51 and the motor 61 to individually control the first rear wheel 12 and the second The speed of rear wheel 13.

Please refer to Figures 7 and 8. According to the foregoing structure, when the vehicle body 1 of this embodiment is in the upright state, its frame 11, first rear wheel 12 and second rear wheel 13 are not tilted relative to the ground. At this time, the corresponding components of the two linkage components 3 are generally horizontally opposite to the left and right, and the connecting rod 4 does not swing forward or backward.

Please refer to Figures 9 and 10. When the rider controls the side tilt of the vehicle body 1, taking the left side tilt as an example, the rider's force of tilting to the left can cause the second rear wheel 13 to experience downward pressure, causing the vehicle body 1 to be tilted relative to the ground. Facing the second rear wheel 13 provides lifting force. Therefore, the force of the ground acting on the second rear wheel 13 can cause the second rear wheel 13 to move upward relative to the frame 11 to lift the swing arm 31 of the left linkage assembly 3 and link its rocker arm 32 and swing block. 33 and the two-way adapter 34, thereby causing the connecting part 41 on the left side of the connecting rod 4 to swing backward and the connecting part 41 on the right side to swing forward, and accordingly transmitted to the two-way adapter 34 and 34 of the right linkage assembly 3 in sequence. The swing block 33, rocker arm 32 and swing arm 31 cause the first rear wheel 12 to move downward relative to the vehicle frame 11. Therefore, when the vehicle body 1 is in a rolling state, the vehicle frame 11 and the first rear wheel 12 The first rear wheel 12 and the second rear wheel 13 are inclined relative to the ground; that is, the first rear wheel 12 and the second rear wheel 13 move up and down relative to the frame 11 without being relatively tilted.

In short, since this invention can control the two linkage components 3 to perform reverse movements simultaneously, the lifting amplitude of the second rear wheel 13 will be the same as the descending amplitude of the first rear wheel 12 (and vice versa), so that Ensure that the first rear wheel 12 and the second rear wheel 13 can maintain contact with the ground during driving, ensure that the first rear wheel 12 and the second rear wheel 13 can provide good grip, and will not cause One wheel is suspended in the air, which can effectively reduce the probability of the vehicle overturning due to unstable center of gravity while driving.

Similarly, when the car body 1 travels on an uneven road surface, when one of the rear wheels is lifted due to the bulge on the ground, the other rear wheel can also perform a reverse action to generate downforce; with the third For example, if the second rear wheel 13 is lifted by a protrusion on the ground, the reaction force provided by the ground to the first rear wheel 12 can be used to create the effect of lifting the first rear wheel 12, whereby the side linkage assembly 3, The connecting rod 4 and the other side linkage component 3 provide the force to suppress the lifting of the second rear wheel 13 . Therefore, the first rear wheel 12 and the second rear wheel 13 can also maintain contact with the ground when traveling on uneven roads, and can reduce the bouncing effect of the vehicle body 1 caused by uneven roads, thereby improving riding comfort. feel. When one of the rear wheels descends due to passing through the cavity, the situation is opposite to the above and will not be described in detail here.

On the other hand, since this embodiment can control the rotation speed of the first rear wheel 12 by the first power source 5, and control the rotation speed of the second rear wheel 13 by the second power source 6, the first rear wheel 12 and the second rear wheel 13 each have an independently controllable power and transmission system, which can facilitate various vehicle dynamic controls. For example, when the first rear wheel 12 and the second rear wheel 13 encounter different terrains, their grip can be controlled by using different torques and rotational speeds, so that the first rear wheel 12 and the second rear wheel 13 The dynamics of the two rear wheels 13 can respectively adapt to the corresponding terrain. Alternatively, when the vehicle body 1 is cornering, the rotational speeds of the first rear wheel 12 and the second rear wheel 13 can also be controlled to increase the steering efficiency and stabilize the vehicle body at the same time. In addition, when one of the power sources fails, the other power source can only be driven at a low speed to move the vehicle body 1 forward, so the first power source 5 and the second power source 6 can have a mutual backup effect.

Please refer to Figure 11, which is a second embodiment of the body tilt control system with dual power sources of the present invention. In this embodiment, the first power source 5 and the second power source 6 can each be a hub motor. And the first power source 5 is installed in the first rear wheel 12, and the second power source 6 is installed in the second rear wheel 13; accordingly, the first power source 5 and the second power source 6 The first rear wheel 12 and the second rear wheel 13 can be driven to rotate respectively, and their rotational speeds can be controlled respectively. In addition, by using a hub motor, the first power source 5 and the second power source 6 can have a simpler appearance, and the convenience of assembly and maintenance is improved.

It is worth mentioning that the first power source 5 and the second power source 6 in the first and second embodiments of the present invention can also be mixed and matched; that is, one of the power sources can be selected as a chain. 55 transmission type, the other power source can be a hub motor type, so the invention is not limited to the type disclosed in the drawing.

To sum up, the body tilt control system with dual power sources of this invention can ensure that the two rear wheels move in opposite directions, so that during driving, even when cornering or traveling on uneven roads, the vehicle body tilt control system can ensure that the two rear wheels move in opposite directions. The two rear wheels maintain contact with the ground and have good grip, and one wheel will not be suspended in the air. This can effectively reduce the probability of the vehicle overturning due to unstable center of gravity during driving, thereby improving riding safety and comfort. . Furthermore, this invention can set up dual power sources so that each of the two rear wheels has an independently controllable power and transmission system, which can facilitate various vehicle dynamic controls.

In addition, in the vehicle body tilt control system with dual power sources of the present invention, almost all its left and right linked components are arranged in an oblong frame and form an integrated component. In one embodiment, the size of the frame is only about 30cm*15cm*10cm, so the vehicle body tilt control system with dual power sources is small in size and easy to manufacture and assemble. It also occupies a very small assembly space and is not easy to restrict the configuration of other components of the vehicle body, which is helpful.
