Description

Electronic Collapsible bicycle

Technical field

The utility model relates to a kind of running vehicle, particularly a kind of fast light Foldable electric bicycle.

Background technology

Along with going deep into of low-carbon environment-friendly Economic concept, bicycle receives more and more people's concern, and bicycle is environmental protection not only; And cost is low, and it is convenient to stop, particularly along with the generation of folding bicycle; It is convenient to let people carry car turnover subway, public transport and block of flats, car owners are positioned over boot or the like up and down; Bicycle folding can directly be gone upstairs through elevator later, has avoided being placed on outdoor contingent losing, and bicycle passes through driven by power; Not only save user's muscle power, and accelerated the speed of bicycle.But the prior electric bicycle all is front-wheel or the trailing wheel through the motor direct-drive bicycle basically, and motor need be fixed on the wheel; Therefore, do not have the function of speed change usually, consumption of current is big under steam for the Electrical Bicycle that drives owing to wheel hub motor; Mileages of continuation is short, and motor-field can produce resistance when riding, after electric weight exhausts in the battery; Need user oneself to pedal, cause certain trouble.Though existing folding bicycle kind is a lot,, most of bicycles folding comparatively loaded down with trivial details, can't fast speed with the bicycle folding folding and unfolding, can only carry by run away goods after folding.

Summary of the invention

The purpose of the utility model is that the stroke that exists to the existing bicycle described in the background technology is short, can't fast folding and folding after the problem that can not carry out, a kind of electronic Collapsible bicycle that can solve foregoing problems is provided.

The technical scheme of goal of the invention that can realize the utility model is following:

A kind of electronic Collapsible bicycle; It comprises car body, has foot-operated power-assist actuating device, front vehicle wheel, rear wheel, handlebar, brake gear, vehicle seat, actuating device, drive disk assembly and the electric component of pedal; Described car body comprises cycle frame head pipe, vehicle frame seat pipe and folding X-member frame, and actuating device is mid-motor, and this mid-motor and foot-operated power-assist actuating device one are fixed in the middle below of car body; The mouth of mid-motor is provided with first sprocket wheel; Be positioned on the mid-motor first sprocket wheel below be provided with the fixed mount of fixing second sprocket wheel, described drive disk assembly is a chain, engagement of chain front end and axis bonded assembly chain wheel; The chain middle part is through first small flywheel and second minor sprocket; First minor sprocket below the chain end portion with chain engages, second minor sprocket above chain the latter half with chain engages, the flywheel on the chain rear end engagement rear vehicle shaft; On car body, be equipped with controller box, be fixed with on the controller box and mid-motor bonded assembly rechargeable battery.

Described X-member frame comprises first cradling piece, second cradling piece and the 3rd cradling piece; The first cradling piece front end is articulated in first hinge-point on the cycle frame head pipe; The rear end of first cradling piece is articulated in to slide and is arranged at second hinge-point on the sliding sleeve on the vehicle frame seat pipe; The second cradling piece front end is articulated in the 3rd attachment point on the cycle frame head pipe, hinged and the 4th hinge-point of the front end of the second cradling piece rear end and the 3rd cradling piece, and the 3rd hinge-point is arranged at the top of first hinge-point; The 3rd cradling piece rear end and vehicle frame seat pipe lower end are hinged, and the position that the 3rd mid-stent is forward and first cradling piece are articulated in the center hinge contact.

Described sliding sleeve below is provided with the positioning element that behind bicycle folding, sliding sleeve is positioned.

The handlebar of bicycle is provided with control power supply opening or closed master cock plate and the speed control crank of control motor speed and the brake lever that cuts off the power supply.

The beneficial effect of the utility model is because the motor of the electronic Collapsible bicycle of the utility model is selected mid-motor for use; Mid-motor and foot-operated power-assist actuating device one are fixed in the middle below of car body; The mouth of mid-motor is provided with first sprocket wheel, drives chain gear through first sprocket wheel, and then drives the flywheel rotation of trailing wheel; Through the engagement of second sprocket wheel assurance chain and first sprocket wheel, chain wheel and flywheel, drive bicycle and move ahead.Be provided with variable gear in the mid-motor, can control rotating speed of motor, and then control the rotating speed of mouth first sprocket wheel of mid-motor through variable-speed controller, and then the moving velocity of control Electrical Bicycle.Because mid-motor adopts gear change, the power of motor is less, and mileages of continuation is longer.In addition, when the people advanced through pedal to pedal, the common electromagnetic resistance of the Electrical Bicycle of existing wheel hub motor was bigger, but the battery-driven car of the utility model does not almost have resistance when manual work is ridden, and is very laborsaving.When Electrical Bicycle need fold, through the X-member frame fast folding, the length of folding back Electrical Bicycle can carry out entering into escalator easily, and folding rate is very fast, can accomplish folding less than 1 second time the soonest.
