Embodiment 1
[0060] Such as Figure 1 to Figure 4 As shown, an electric booster 1 is arranged at the rear of the human-driven vehicle 2, and the electric booster 1 includes a booster wheel 14, an energy supply module 13 and a swing arm 11, one end of the swing arm 11 is connected with the vehicle frame 21, and the other end of the swing arm 11 Connect with the booster wheel 14, the booster wheel 14 is in contact with the ground, and the booster wheel 14 is controlled by the driving intention detector 17 (the rider twists it by hand or steps on it with his feet to detect the rider's intention, that is, the throttle) , the energy is provided by the energy supply module 13 to push the human-driven vehicle 2 forward.
[0061] detailed,
[0062] Such as Figure 1 to Figure 4 As shown, the connection between the swing arm 11 and the frame 21 has two swing degrees of freedom, which are the up and down swing degrees of freedom away from and close to the ground, and the swing degrees of freedom t...
Embodiment 2
[0072] In order to make the first embodiment more compact and reduce the rolling resistance when riding purely by human power. Such as Figures 5 to 8 As shown, the grounding point of the booster wheel 14 is at the rear of the swing axis of the swing arm 11, and the connection between the swing arm 11 and the vehicle frame 21 has only one swing degree of freedom, that is, there is only an up and down swing degree of freedom in the direction away from and close to the ground. To adapt to the pitching (adapting to road undulations) attitude of the human-driven vehicle 2; this swing degree of freedom can be a rotary pair, or both can be a threaded pair.
[0073] When the grounding point of the rear wheel of the power-assisted wheel 14 and the driving vehicle 2 is very close in the forward direction, the sliding of the power-assisted wheel 14 brought by the steering is also small on the ground. In addition, it is not necessary in most cases when turning. When power-assisted, the ...
Embodiment 3
[0079] In order to realize that the electric power assist device 1 can automatically detect the intention of the rider, thereby automatically assisting or not assisting, so as to match the intention of the rider, such as Figure 9 As shown, on the basis of Embodiment 1, a force sensor 16 is added to the swing arm 11, and the controller (which has the function of detecting and controlling the rotation of the booster wheel 14, is fixedly connected with the swing arm 11, not shown in the figure, is the current There is a technology) to detect whether the power-assisted wheel 14 has a tendency to move away from or approach the human-driven vehicle 2, and the specific degree, and cooperate with the control strategy to achieve matching with the rider's intention. Further, the above problem can be transformed into a problem of detecting whether the swing arm 11 is stretched or compressed, and the specific degree. Furthermore, that is, the swing arm 11 is designed to be deformed when ...
