Abstract

The electric vehicle has three wheels: a front wheel and two back wheels. The front wheel is a steering wheel. According to design, both the front wheel and the back wheels can serve as the electric wheel(s) (driving wheel(s)). The diameter of the front and back wheels is about 20 centimeters (the diameter cannot be overlarge, but the front wheel can be bigger than the back wheels). The vehicle frame is of a chassis type (the anti-collision bars are arranged on the edge of the chassis), and is 70 centimeters long and 45 centimeters wide, and a seat plate is arranged above the back wheels. The whole design is shown by a figure 1. According to the design, the diameters of the wheels are small and the sit type structure is adopted, so the vehicle is shorter and has a very small centrifugal force; the three wheels well maintain the balance of the vehicle, so the electric vehicle is high in safety, can avoid traffic accidents as many as possible; and the small volume allows the electric vehicle to be parked in a small floor area. Figure description is as follows: the figure 1 is the lateral schematic diagram of the electric vehicle, wherein 1 represents the front wheel (a wheel drum drives a motor); 2 represents the back wheels; 3 represents the chassis type vehicle frame; 4 represents a steering cock (rod); 5 represents the seat plate; 6 represents a battery pack; 7 represents the anti-collision bar(section); 8 represents a damping spring; 9 represents a backrest; 10 represents a brake; 11 represents a headlight; 12 represents a goods container; and 13 represents a front shock absorber.

Description

The sitting posture battery-driven car

Technical field: the present invention relates to the vehicle technology field.

Background technology: existing car motor-car all is a striding type, and speed is fast, and safety performance is not high, and speed is all per hour about 40 kilometers, and the battery-driven car of this speed per hour sodium is gone within the motor bike management, is very limited in the city.

Summary of the invention: the present invention provides a kind of battery-driven car of sitting posture, and speed is per hour about 20 kilometers, and safety performance is higher, and floor area is few when parking, to realize urban safety, Personal Transporter's demand easily.

The object of the present invention is achieved like this: this battery-driven car is three wheels, last back two;

Front-wheel is a steering wheel; Different according to design, front and rear wheel can be done electric drive wheel (main wheel); The front and back wheel diameter is (can not be excessive, can front-wheel big, trailing wheel be little) about 20 centimeters; Vehicle frame is disc type (web is equipped with the anticollision bar), is about 70 centimeters, and wide about 45 centimeters, seat is on trailing wheel top; Unit design is seen Fig. 1.

Because adopt above-mentioned design, the diameter of wheel is little, is again sitting posture, the height of car body is also just little, its centnifugal force is just much smaller, adds three wheels, and balance is good, thereby this electric safe performance height, traffic accident rate is few, and volume is little, takes up an area of just few when parking.

Description of drawings: Fig. 1 is this battery-driven car side schematic view.1 is front-wheel (wheel hub translator) among the figure; 2 is trailing wheel; 3 is the chassis type vehicle frame; 4 is direction tap (bar); 5 is seat; 6 is battery pack.7 are collision bar (section); 8 is damping spring; 9 is backrest; 10 are brake; 11 is illumination headlights, and 12 is articles holding box, and 13 clamor for preceding damping.

Fig. 2 is this battery-driven car plan sketch.1 is front-wheel (wheel hub translator) among the figure; 2 is trailing wheel; 3 is the chassis type vehicle frame; 4 is direction tap (bar); 5 pull for trailing wheel shelves mud; 6 is battery pack.7 are collision bar (section); 8 is front mudguard; 9 is footboard; 10 are brake; 11 is front fork and bumper, and 12 is articles holding box, and 13 is speed electrical control handle.

Embodiment: accompanying drawing is further specified below in conjunction with embodiment:

1. this battery-driven car main wheel can be counted front-wheel, also can be designed as trailing wheel.

2. this electric vehicle motor rotating speed is designed to about 20 kilometers of speed per hours according to wheel size.

3. this battery-driven car adopts the control of second gear circuit.

4. this battery-driven car can be used as the wheelchair use.

Claims
