Embodiment 1

[0045] Such as figure 1 and figure 2 As shown, the first bracket 1 is fixedly connected to the vehicle frame 7, the first end 21 of the second bracket 2 is connected to the first bracket 1 in a swinging manner, the second end 22 of the second bracket 2 is fixedly connected to the powertrain 3, and the powertrain Cheng 3 drives the driving wheel 4 to rotate. When power is applied, the driving wheel 4 contacts the side of the wheel assembly 6 and drives the wheel assembly 6 to rotate through friction. The component force of this friction force presses the driving wheel 4 and the side of the wheel assembly 6 .

[0046] Such as image 3 As shown, when there is no booster, that is, when the powertrain 3 does not receive a booster command, the powertrain 3 does not rotate, and the drive wheel 4 and the wheel assembly 6 are not in contact. When assisting, when the powertrain 3 receives the assist command and starts to rotate, it applies a driving torque T to the driving wheel 4 ...

Embodiment 2

[0056] Above-mentioned embodiment only is provided with booster device on one side of wheel assembly 6, as Figure 4 As shown, the force F of the driving wheel 4 pressing on the wheel assembly 6 2 It can only be resisted by the structural strength of the wheel assembly 6, in order to better balance this force, such as Figure 6 and Figure 7 As shown, the booster device shown in Embodiment 1 is set as a mirror image with respect to the equatorial plane of the wheel assembly 6 to form Embodiment 2, that is, two sets of booster devices in Embodiment 1 are symmetrical about the equatorial plane of the wheel assembly 6 The arrangement constitutes the second embodiment, and the geometric principle remains unchanged. It also increases the redundancy of the system and improves the reliability.

[0057] The output shafts of the powertrains 3 on both sides will simultaneously rotate in the set direction and rotate at the speed required by the instruction when receiving the power ass...

Embodiment 3

[0059] Such as Figure 8 to Figure 11 As shown, on the basis of the first embodiment above, the power booster is rotated as a whole by 90° so that the driving wheel 4 is in contact with the inner peripheral surface of the wheel rim of the wheel assembly 6. When in contact, the rotation axis of the driving wheel 4 is in contact with the wheel assembly 6 The axes are parallel to obtain embodiment three, the radial force produced during driving is borne by the wheel assembly 6, the wheel assembly 6 has high radial strength, and the radial force will not have a negative impact on the structure of the wheel assembly 6.

[0060] Such as Figure 8 and Figure 9 As shown, the first bracket 1 is fixedly connected to the vehicle frame 7, the first end 21 of the second bracket 2 is connected to the first bracket 1 in a swinging manner, the second end 22 of the second bracket 2 is fixedly connected to the powertrain 3, and the powertrain Cheng 3 drives the driving wheel 4 to rotate. Whe...

Abstract

The invention discloses a boosting device, belonging to the field of electric vehicles, and relates to a boosting device for a human-powered vehicle. A first bracket is fixedly connected to a frame, afirst end of a second bracket is connected to the first bracket in a swing mode, a second end of the second bracket is fixedly connected to a powertrain, and the powertrain drives a driving wheel torotate. When boosting is not performed, the powertrain does not rotate, and the driving wheel does not make contact with a wheel assembly; when boosting is performed, the powertrain starts to rotate,and the feedback torque acts on the second bracket to make the second bracket swing around a swing axle on the first bracket, the driving wheel is driven to make contact with the side of the wheel assembly, and the driving wheel drives the wheel assembly to rotate by friction force, and the component of the friction force presses the driving wheel and the side of the wheel assembly. By applying the boosting device, the original vehicle component does not need to be disassembled, the cost is low, the boosting device does not make contact with the wheel during autonomous riding, and the combination and separation of a motor and the wheel is realized by the feedback torque when the system is started, thereby solving the problems in the prior art.

Description

technical field [0001] The invention discloses a booster device, which belongs to the field of electric vehicles, relates to human-driven vehicles, and in particular to a booster device for bicycles. Background technique [0002] Human-powered vehicles (for example: bicycles, human-powered tricycles and human-powered four-wheeled vehicles, etc.) can only be driven by people's own physical strength. If a booster device can be added to it, it can reduce human physical exertion, or in the case of a certain amount of physical strength. Extend your ride distance. With the progress of urbanization and the advocacy of green traffic, more and more people use bicycles to commute and play. Since the distance of commuting and playing is usually longer, it becomes a demand to increase the cycling distance under the condition of certain physical strength. [0003] The prior art has the following three solutions for how to convert the rotational motion of the motor into the motion of a r...
