Compact folding electric scooter with large wheel diameter

Abstract

A compact electric vehicle, including a dragging arm extending obliquely downward from the rear of the steering shaft sleeve, and the dragging arm is connected to the pedal; in the unfolded state, the body is L-shaped; in the folded state, the body is a When the vehicle is viewed from the side, the energy compartment is at least partially located between the steering column of the vehicle body and the pedals, and the steering column of the vehicle body, the pedal beam, and the battery compartment form a compact body. The energy bin is arranged at the rear of the steering shaft column of the car body or the front of the saddle tube. When folded, the space of the car body is fully utilized. Based on traditional human-powered scooters, it is easy to upgrade to electric scooters; usually, the wheel diameter can be set to 8-16 inches, the pedals are very close to the ground, and the center of gravity is very low. . It can realize the tight folding of the body, thin and narrow body.

Description

Technical field: [0001] This design innovation involves miniature electric vehicles, electric scooters with directional control rudders, and improvement of electric scooters. Possibly the main category. Specifically, appearance category 21-02 is involved. This type of vehicle is equipped with large wheels and can become a so-called miniature electric bicycle or an approximate miniature electric bicycle, so it also involves the field of electric bicycles. Background technique: [0002] There are too many private cars in modern cities, the transportation system is not well developed, and the whole city is extremely crowded. The public urgently needs a compact, light and small folding vehicle, especially light, short-distance, small in size after folding, and easy to carry around. micro electric vehicles. This type of means of transportation will become more popular and enter the public eye. For such vehicles, size, weight, and volume are important. [0003] Electric pedal...

AI Technical Summary

Problems solved by technology

Although this kind of product is small in size, it is relatively heavy. It is possible to lift it for a short time, but it is difficult to carry it or lift it for a long time. Due to the small body of the car, if it is placed outdoors, it is easy to lose

[0004] After years of development, the body folding mechanism of human-powered scooters and existing electric skateboards is relatively mature. In order to obtain better passability when driving, the diameter of the wheels must be increased and the height of the pedals must be reduced. Therefore, the body steering shaft There is a protruding drag arm extending obliquely at the rear of the bushing. Its advantages are that it is easy to install large front wheels. At the same time, the distance between the pedal and the ground is relatively close, and the center of gravity of the vehicle body is relatively low. However, it has a huge defect:

[0009] However, this type of electric scooter also has some disadvantages: 1. In order to achieve an ideal longer mileage, the volume of the lead-acid battery compartment arranged at the pedal part is relatively large, causing the upper surface of the pedal to be relatively high from the ground, and the human foot It is very inconvenient to frequently and repeatedly step on the pedals to the high position, especially in emergency situations or when braking to stop, the feet need to quickly touch the ground to support the car body so as not to fall, which is not only inconvenient but also unsafe

2. The volume of the lead-acid battery compartment set on the pedal part is relatively large, which occupies the quantity and volume of the loaded and transported things (goods)

3. The structure of this type of electric scooter is loose, the whole body is bloated and bulky, takes up space, the transportation cost of the whole vehicle is high, and storage is inconvenient
