Abstract

An electric bicycle comprises a frame, a saddle 5, a handlebar 1, a front wheel 6, a rear wheel 12, a battery, a battery box 3 and a base 8 of the battery box. A girder 4 of the frame takes a form of U-shape; the battery is arranged inside the battery box, which is embedded in the base of the battery box; the lower bend segment of the girder of the frame is provided with a horizontal section 10, on which the base 8 of the battery box is fixed. The two side surfaces of the base of the battery box are respectively provided with a dead pedal fender 9 which stretches out from the side face. As the battery, battery box and the base of the battery box are arranged on the horizontal section at the lower bend segment of the girder, therefore, a gravity center of the bicycle is particularly low and the bicycle is convenient for a cyclist to get on or off as a common bicycle with relatively wider distance down to the ground. The fact that the two sides of the base of the battery box are respectively provided with dead pedal fenders which causes no trouble for bicycling by pedal force and on which feet of the cyclist can rest results in more comfortable and freer bicycling. A battery box 3 is horizontally placed, thus being convenient for application.

Description

Electrical Bicycle

(1) technical field:

The utility model relates to a kind of structure of Electrical Bicycle.

(2) background technology:

Existing Electrical Bicycle generally is made up of vehicle frame, vehicle seat, handlebar, front-wheel, trailing wheel, storage battery, accumulator box and accumulator box base, and a motor is arranged on the trailing wheel, advances in order to drive car.Storage battery, accumulator box and accumulator box base generally are installed on the front frame of V-type spider of vehicle frame, and the space that the cyclist gets on and off is less, and the weight of storage battery is heavier, and the center of gravity of whole car leans forward, and car travels easily unstable.The structure of another kind of Electrical Bicycle, the Electrical Bicycle introduced of Chinese patent 99229866.0 for example, its storage battery are placed on the sit down rear of spider standpipe of car.The space that gets on and off has been strengthened, but the installation and removal of storage battery are convenient inadequately, and the center of gravity of car load is back partially higher.

(3) summary of the invention:

The purpose of this utility model is that a kind of space that gets on and off of proposition is bigger, the structure of the Electrical Bicycle that the car load center of gravity is lower.

This Electrical Bicycle, comprise vehicle frame, vehicle seat, handlebar, front-wheel, trailing wheel, storage battery, accumulator box and accumulator box base, the crossbeam of vehicle frame becomes U-shaped, storage battery is contained in the accumulator box, accumulator box is embedded in the accumulator box base, the downward bent part of described crossbeam has a horizontal segment, and described accumulator box base is fixed on the horizontal segment of above-mentioned crossbeam, and a fixing step wing plate 9 is respectively arranged on the left and right sides face of accumulator box base.

The storage battery of this Electrical Bicycle, accumulator box and accumulator box base are owing to be positioned on the horizontal segment of crossbeam downward bent part, so the center of gravity of car load is low especially, the spacing that the cyclist gets on and off is identical with the spacing of ordinary bicycle, and is rather spacious.And, owing to fixing step wing plate is arranged, neither hinder the foot-operated function that drives in the both sides of accumulator box base, can supply cyclist's leg rest again, movable relatively tread plate obviously has more convenient, safer, more comfortable advantage.

(4) description of drawings:

Accompanying drawing 1 is the integral structure figure of this Electrical Bicycle;

Accompanying drawing 2 is the scheme drawing of accumulator box and installation site thereof.

(5) specific embodiment:

As shown in Figure 1, this Electrical Bicycle comprises vehicle frame, vehicle seat 5, handlebar 1, front-wheel 6, trailing wheel 12, storage battery, accumulator box 3 and accumulator box base 8.4 one-tenth U-shapeds of the crossbeam of vehicle frame, storage battery are contained in the accumulator box 3, and accumulator box is embedded in the accumulator box base 8, and accumulator box base 8 is fixed on the horizontal segment 10 of crossbeam.The center of gravity of car load is fallen very lowly.Accumulator box 3 is horizontal positioned, and it is very convenient to pick and place.One fixing step wing plate 9 is respectively arranged, the usefulness of leg rest when supplying to ride on the left and right sides face of accumulator box base 8.11 is middle support among the figure.

As shown in Figure 2, the accumulator box base 8 of this Electrical Bicycle can be combined by left and right sides two parts, and two parts accumulator box base is clipped in the middle the horizontal segment 10 of crossbeam, assembles more convenient.About described fixedly step wing plate 9 be in the outside of left and right sides two parts accumulator box base respectively.

As shown in Figure 1, this Electrical Bicycle can also comprise an air baffle 7, and this air baffle is fixed on the preceding pipe 2 of described crossbeam 4.Both make vehicle modeling more attractive in appearance, can be bicyclist's shading wind and rain again, helped protecting Teng's joint portion.
