Embodiment 1

[0044] like 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 swingingly connected to the first bracket 1, and the second end 22 of the second bracket 2 is fixedly connected to the power assembly 3. The driving wheel 4 is driven to rotate in three parts. When the power is boosted, the driving wheel 4 is in contact with the side of the wheel assembly 6, and the wheel assembly 6 is driven to rotate by the friction force. The component of this friction force presses the driving wheel 4 and the side of the wheel assembly 6 .

[0045] like image 3 As shown, when the power is not assisted, that is, when the power assembly 3 does not receive an assist command, the power assembly 3 does not rotate, and the driving wheel 4 and the wheel assembly 6 are not in contact. When assisting, when the powertrain 3 starts to rotate after receiving the assist command, a driving torque T is applied to th...

Embodiment 2

[0053] 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 Image 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.

[0054] 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 assi...

Embodiment 3

[0056] like 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.

[0057] like 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 3 drives the driving wheel 4 to rotate, and when power ...

Abstract

The invention discloses a manpower drive vehicle power assisting device, belongs to the field of electric vehicles, and relates to power assisting devices used for manpower drive vehicles. First supports are fixedly connected with a vehicle frame, the first ends of second supports are in swinging connection with the first supports, the second ends of the second supports are fixedly connected withpower assemblies, and each power assembly drives a drive wheel to rotate. When power assistance is not conducted, the power assemblies do not rotate, and the drive wheels do not make contact with a wheel assembly; and when power assistance is conducted, the power assemblies start to rotate, the feedback moment acts on the second supports, so that the second supports swing around swing shafts on the first supports, the drive wheels are driven to make contact with the side faces of the wheel assembly, the drive wheels drive the wheel assembly to rotate through the friction force, the drive wheels and the side faces of the wheel assembly are tightly pressed through the component force of the friction force, and the power assisting device is symmetric about the equatorial plane of the wheel assembly. Original vehicle components do not need to be detached, cost is low, combination and separation of a motor and a corresponding wheel are achieved through the feedback moment generated when anapplication system is started, and the problems existing in the prior art are solved.

Description

technical field [0001] The invention discloses a power-assisting device for a human-driven vehicle, which belongs to the field of electric vehicles, relates to a human-driven vehicle, and particularly relates to a power-assisting device for a bicycle. Background technique [0002] Human-driven vehicles (such as bicycles, human-powered tricycles, human-powered four-wheeled vehicles, etc.) can only be driven by human physical strength. If a power assist device can be added to it, the physical energy consumption of human beings can be reduced, or under the condition of certain physical strength consumption Extend your riding distance. With the process of urbanization and the advocacy of green transportation, more and more people use bicycles to commute and play. Since the distances for commuting and playing are usually long, increasing the riding distance under the condition of certain physical strength has become a demand. [0003] In the prior art, there are the following th...
