Abstract

A portable electric bicycle is designed into two parts, namely a portable electric device part and a bicycle body part according to the principles of convenient carrying, portability and safety. The portable electric device comprises a machine case, a motor, a battery cell and a controller, wherein the motor and the controller are arranged inside the machine case, the battery cell can be arranged inside or outside the machine case, and the output shaft of the motor is enclosed by a driving gear. The portable electric device is connected with a rack fixed on the bicycle body into a whole through a positioning pin lock on the machine case. The utility model relates to the portable electric bicycle with portability, safety, high efficiency and low cost.

Description

Portable electric device bicycle

Technical field

The utility model relates to a kind of Electrical Bicycle, especially a kind of can be by the simple button of portable electric device be hung over the portable electric device bicycle that the mode in the bicycle body constitutes.

Background technology

As everyone knows, the core component that present Electrical Bicycle all adopts electrical motor, controller, subtract Electrical Bicycle such as speed wheel Grains is fixing onboard, and only storage battery can portable thinking design.To making existing Electrical Bicycle not only be with the electrical motor wheel hub to ride to cause riding effort, efficient low because of having to, also the brake safe performance is poor, the productive costs height because of burdensome heavy (40kg is generally arranged) causes, so that it is motorized that Electrical Bicycle that should be succinct, light for safety is tending towards, not only wasted limited electric energy, also will account for parts that car load price 3/4 is worth and all fix onboard design because of this, will make the user who lives upstairs, because of car being moved home in case stolenly just suffer heavy losses.

Summary of the invention

The purpose of this utility model just provides a kind of light, safe, efficient, electronic device bicycle of low cost and portable.

The utility model by be easy to carry, light safe principle is designed to portable electric device and bicycle body's two parts, wherein the portable electric device comprises cabinet, electrical motor, storage battery, controller, electrical motor, controller are installed in the cabinet, storage battery can be located in the cabinet, also can be located at outside the cabinet suit driven wheel on the output shaft of electrical motor.The portable electric device is connected as a single entity by location lock on the cabinet and the carriage that is fixed in the bicycle body, and the centering type power-transfer clutch is set on the carriage, and is meshed or left by driven wheel and the tooth floral whorl tire on handle or the brake interlock cable wire control motor output shaft.

Only need turn on the power switch, unclamp the centering type power-transfer clutch during use, driven wheel just meshes with tooth floral whorl tire, regulates motor speed by speed control crank, and the tooth floral whorl tire of the driving gear drives bicycle on the motor output shaft is realized the driven by power bicycle.

Owing to adopt scheme described in the utility model, after portable electric device bicycle is divided into two parts of portable electric device and bicycle body, not only be easy to carry, also reached on ordinary bicycle, directly to detain and hung the purpose that the portable electric device constitutes inexpensive simple and easy portable electric device bicycle, for vast bicycle user provides a kind of solution with the ordinary bicycle motorized, simultaneously, because the value of portable electric device is far above bicycle, so the portable electric device is put forward when going home also that Electrical Bicycle is the most costly part to be carried and having gone home, stay just about one 200 yuan bicycle without, avoided the in a single day stolen disastrous problem of general Electrical Bicycle effectively, so that reached the purpose of theft protection indirectly.

The specific embodiment

Embodiment one:

In Fig. 1, the cabinet 9 of portable electric device is designed to across the shape of a saddle on bicycle quick both sides, electrical motor 6, storage battery 10, controller 4 are placed on respectively in the shape of a saddle cabinet 9, and driven wheel 8 is in the centre of shape of a saddle cabinet 9, and with the concentric suit of the output shaft of electrical motor 6.When the screw convex of cabinet 9 belows recline bracket 12 and hold out against with crotch after, dowel hole on the cabinet 9 just with carriage 12 on dowel hole be on the same axis, after location lock 15 inserts and locks, cabinet 9 has been linked as one with carriage 12, because the pulling force of spring 11 makes driven wheel 7 and tooth floral whorl tire 8 in the engagement contact condition, so can electronicly at any time ride.

Because the utility model is with storage battery 10, electrical motor 6, controller 4, driven wheel 7 grades are combined in the portable electric device cabinet 9 and by the vehicle electric circuitry principle and have finished electrical connection, so hung on the carriage 12 of bicycle 1 by button by said process when portable electric device 2 after, only need and to have gathered the speed control crank signal wire (SW), the joint of brake lever signal wire (SW) inserts on the controller signals line socket 3, just all installations and connection work have been finished, turn on the power switch 5 and unclamp centering type power-transfer clutch 14 this moment to normality, then driven wheel 7 just is in the engagement position contacting with tooth floral whorl tire 8, so can regulate the rotating speed of electrical motor 6 by speed control crank, and, reach the purpose that portable electric device 2 of the present invention drives bicycle 1 by the driven wheel 7 driving gear floral whorl tires 8 that directly are sleeved on the motor output shaft.And ride or when sliding, a position that then only needs centering type power-transfer clutch 14 is transferred to clutch gets final product if will ride.

In addition, the utility model portable electric device bicycle is that gear-driven mode is applied directly on the cycle casing, and this tooth floral whorl tire 8 actvies have overcome many deficiencies such as existing friction-driven efficient is low, the rainy day skids, abrasion tire.

The clutch of the centering type power-transfer clutch 14 on the carriage 12 of the utility model portable electric device bicycle can be by handle or brake interlock cable wire dual mode regulating control.

Portable electric device 2 in the utility model portable electric device bicycle can be installed on suitable positions such as the front-wheel car body, trailing wheel car body of unpowered vehicles such as bicycle, three-wheel vehicle according to different demands.

Embodiment two:

In second embodiment principle assumption diagram shown in Figure 3, embodiment two is exactly that storage battery 10 is told from the cabinet 9 of portable electric device with embodiment one unique difference, is installed on separately on the bicycle, and purpose is in order to alleviate the weight of handlebar when driving front-wheel.Its advantage be not only compact conformation, button hang easy, be fit to various types of bicycles, but also can too increase under the prerequisite of handlebar load being unlikely to, high-capacity storage battery is installed, other is identical with embodiment one.
