Abstract

The utility model belongs to electric bicycles and in particular relates to an electric bicycle with adjustable current limiting value. The electric bicycle comprises a bicycle body, a battery, a controller and a handlebar, and is characterized in that an current adjuster is arranged inside the controller and a switch button is connected outside the controller; the switch button is arranged on the handlebar and the current adjuster is connected with the switch button on the handlebar through a lead. The switch button is connected outside the controller and each time when the switch button is pressed, the current limiting value of the controller changes, and the current limiting value of the controller can be changed in the order of large-medium-small or in the reverse order. When the user climbs a slope, which requires large current, the bicycle can be conveniently turned to the large-current state through the button, while in other occasions, the bicycle can be turned back to small-current state so as to protect the controller and the battery.

Description

A kind of Electrical Bicycle of scalable cut-off current

Technical field

The utility model belongs to the Electrical Bicycle class.

Background technology

Along with the fast development of modern city construction and the raising of people's living standard, and the enhancing of people's energy-conserving and environment-protective consciousness, battery-driven car economic, convenient, practical, environmental protection has become the vehicle that increasing people goes on a journey.But present battery-driven car is after dispatching from the factory, cut-off current promptly is fixed, can not change, like this, when the user was in climbing, if electric current is not enough, promptly under power was big, rotating speed of motor can be very low, at this moment efficient will be very low, even may be low to moderate about 20%, and promptly most energy becomes heat energy and dissipates, wasted energy, owing to produce heat in a large number, the metal-oxide-semiconductor in the controller is easy to sustain damage simultaneously, and the life-span shortens greatly, at this moment just need big electric current, and the controller of existing common electrical motor-car can not provide big electric current as required; When the user starts car on level road, do not need too big electric current, existing common electric vehicle controller can not reduce electric current again, easily battery and controller is impacted.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, a kind of more reasonable structure is provided, uses the Electrical Bicycle of the scalable cut-off current that has more human oriented design of more flexible, battery-driven car cut-off current adjustable size.

The technical solution of the utility model is as follows:

A kind of Electrical Bicycle of scalable cut-off current, comprise car body, battery, controller, handgrip, it is characterized in that: current relay is housed, an external shift knob in the controller, shift knob is located on the handgrip, and current relay is linked to each other with shift knob on the handgrip by lead.

Controller outside connected switch button of the present utility model whenever clicks shift knob, and the cut-off current of controller changes once, can change by large, medium and small or opposite order.When user climbing, when needing big electric current, can be transferred to current state easily by this button, the power of controller will increase, and rotating speed can improve, when rotating speed improves, efficient will significantly improve, efficient can make the real output function improve again when improving, thereby rotating speed improves, and this is a benign cycle, the heat of controller generation at this moment will reduce, thereby can reduce damage, increase the service life of controller, also just strengthen the performance of car load metal-oxide-semiconductor; And, then can adjust back to the small electric stream mode, with protection controller and battery as user in other cases the time.

The specific embodiment

As shown in Figure 1, 2, a kind of Electrical Bicycle of scalable cut-off current, comprise car body 1, battery 2, controller 3, handgrip 4, it is characterized in that: current relay 5 is housed in the controller 3, an external shift knob 7, shift knob 7 is located on the handgrip 4, and current relay 5 is linked to each other with shift knob 7 on the handgrip by lead 6.

The utility model is whenever by a shift knob 7, and the cut-off current of controller changes once, can change by large, medium and small or opposite order.

Claims
