ELECTRIC BICYCLE

Abstract

An electric bicycle has an outer double frame, on which a steering plug with a handlebar and a front wheel with a sleeve is mounted in front of a hinge, and a rear wheel with the sleeve is attached behind. A seat is secured to the outer double frame. An internal double frame is built into the outer double frame, each double frame being a spatial construction of profile tubes rigidly connected by interconnected fastening elements with cutouts into which a battery unit is mounted. The fastening elements are triangular in shape, with at least three of these elements being located in front of the outer double frame, and one element attached to the rear side of the outer double frame. Inside the structure is strengthened by vertical elements in the angle form, with the possibility of horizontal movement. The seat is fixed to the outer double frame on a triangular element. Rear motor-wheel connected to the battery unit secured by the shock absorber element to the outer double frame on one side and a movable pendulum pivotally secured to the outer double frame on the other. The rear motor-wheel is also attached to the controller.

Description

BRIEF DESCRIPTION OF DRAWINGS

[0014] FIG. 1 shows an electric bicycle according to an embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The electric bicycle has the outer (1) double frame, on which the steering plug (2) with the handlebar and the front (3) wheel with the sleeve is mounted in front of the hinge, and the rear (4) wheel with the sleeve is attached behind. The seat (5) is secured to the outer (1) double frame. An internal (6) double frame is built into the outer (1) double frame, each double frame being a spatial construction of profile tubes rigidly connected by interconnected fastening elements (7) with cutouts into which a battery unit (8) is mounted. The fastening elements (7) are triangular in shape, with at least three of these elements being located in front of the outer (1) double frame, and one element attached to the rear side of the outer (1) double frame. Inside the structure is strengthened by vertical elements in the angle form (9), with the possibility of horizontal movement. The seat (5) is fixed to the outer (1) double frame on a triangular element (10). Rear motor-wheel (11) connected to the battery unit (8) secured by the shock absorber element (12) to the outer (1) double frame on one side and a movable pendulum (13) pivotally secured to the outer (1) double frame on the other. The rear motor-wheel (11) is also attached to the controller (14).

[0016] The electric bicycle contains an electric motor (not shown). The sprocket and the pedal drivetrain is mounted at the bottom of the outer (1) dual frame, and a rotation sensor (not shown) is connected to the drivetrain.

[0017] The electric bicycle may additionally include a gas handle, proximity sensors, positioning system, on-board computer and alarm system (not shown).

[0018] Given that the movement of an electric bicycle is provided in full or in part by the motor-wheel (11), which allows to increase the speed and compensate, up to 100% of effort, the basic principle of the electric bicycle is the ability to move with the use of electric traction and without the use of force from the passenger. The electric bike also offers the ability to move on and off pedaling like a normal bicycle, for which the electric bike should be designed and constructed to accommodate the following elements: battery unit (8) with charge control and charge/discharge balance, controller (14), rotary sensor (not shown) and motor (not shown). The electric bicycle can also be equipped with a gas handle, proximity sensors, positioning system, alarm system, on-board computer (not shown). But this equipment is ancillary and does not affect the construction features of the electric bicycle.

[0019] The electric bicycle uses the following motion algorithm: when pedaling, the rotation sensor gave a signal to the controller (14) that the motion has started. The controller (14) gives signal the battery unit (8) to supply the necessary power to the motor-wheel (11). The voltage and, accordingly, the power that the motor-wheel (11) develops depends on the speed of pedal rotation. You can also start the movement with the accelerator handle or the gas button. Then the speed and the intensity of the movement will depend on the angle of rotation of the accelerator handle.
