Abstract

The utility model relates to an electric and foot two purpose bicycle, belonging to a vehicle. The aim of the utility model is realized through that the stator motor is provided with a pair of shafts, and a control device, a lifting groove, a lifting wire, a thread and a gear are provided between the main and auxiliary shafts. When the electric and foot two purpose bicycle is run by feet, the lifting wire is hidden in the lifting groove, and the auxiliary shaft and a rotor are synchronously rotated, and when the electric and foot two purpose bicycle is electrically run, the lifting wire is picked up under the action of the picking thread to clamp the annular gear of the auxiliary shaft, the auxiliary shaft and the main shaft become integration, and the rotor is rotated around the auxiliary shaft. Compared with the prior art, the electric and foot two purpose bicycle has the advantage that the electric and foot two purpose bicycle is used as same as the general bicycle when run by the feet.

Description

The electric pedal dual-purpose bicycle

Technical field: the utility model relates to a kind of electric pedal dual-purpose bicycle, belongs to the vehicle.

Background technology: present Electrical Bicycle, when foot-operated operation and inertia when advancing, the motor rotor that is contained on the rear axle rotates around stator, stator coil cutting rotor magnetic field, produce the electromagnetism antagonistic force, have a strong impact on the foot-operated functions of use of Electrical Bicycle, and slacken the power that inertia advances.

Summary of the invention:

The purpose of this utility model is to overcome above shortcoming, and a kind of electric pedal dual-purpose bicycle is provided, and this car does not have the influence of above electromagnetism antagonistic force, use the same with ordinary bicycle when foot-operated operation.

The utility model is to realize that by the improvement that Electrical Bicycle is contained in the stator in the electrical motor on the rear axle other positions are not all changed.

The stator that existing Electrical Bicycle is contained in the electrical motor on the rear axle is made up of main shaft and the armature core that is fixed on the main shaft.The utility model is to the improvement of this motor stator, be in motor stator, to increase by a countershaft, this countershaft is cylindrical, there is axis hole at the center, main shaft penetrates countershaft and is enclosed within on the main shaft from axis hole, the two ends of countershaft respectively have a bearing and main shaft to be connected, countershaft can be around main axis rotation by bearing, armature core is fixed on the countershaft, around main axis rotation, is provided with control setup between an end of countershaft and the main shaft with countershaft in addition, this control setup is made up of three parts: 1., the steel gear that goes in ring, this gear inner edge has the triangle teeth groove, and this teeth groove is on one side perpendicular to the axle center, and another side is a slope shape, in the smooth embedding countershaft of the outer rim annular tooth race, and be fixed on the countershaft; 2., be the very heavy cell body of steel, profile is the flattened cylindrical body, there is axis hole at the center, respectively there is a very heavy groove axis hole both sides, this very heavy groove one end is circular, the other end is the triangle that is opened on the cylinder outer rim, penetrates in the central shaft hole of main shaft by very heavy cell body, and should very heavy cell body be fixed on countershaft and goes in ring on the corresponding main shaft of gear; 3., the steel Semen Euphorbiae, this Semen Euphorbiae one end is circular, is placed in the round nose of very heavy groove, the other end is a triangle, is placed in the very heavy groove of other end triangle, and the leg-of-mutton end of Semen Euphorbiae is under the effect of elasticity Pick Wire, with the Semen Euphorbiae nose circle is fulcrum, can move up and down in very heavy groove.

Description of drawings: Fig. 1: among the motor stator longitudinal diagram figure: 1, main shaft 2, armature core 3, countershaft 4, bearing 5, control setup Fig. 2: among the control setup scheme drawing figure: 6, belt gear 7, triangle teeth groove 8, very heavy groove 9, Semen Euphorbiae 10, Semen Euphorbiae round nose 11, Semen Euphorbiae triangle end 12, elasticity Pick Wire 13, very heavy cell body

The specific embodiment: the function of control setup is Electrical Bicycle when foot-operated operation, or the stator countershaft of electrical motor synchronously around main axis rotation, thereby does not have the phenomenon in stator coil cutting rotor magnetic field with rotor under the effect of rotor field during the inertia operation.So there is not the influence of electromagnetism antagonistic force, so this battery-driven car can use equally with ordinary bicycle, when the charged use of battery-driven car, the control setup Semen Euphorbiae of motor stator lifts under the effect of elasticity Pick Wire, be stuck in the teeth groove of the gear that goes in ring on the countershaft, countershaft and main shaft are become one, and rotor rotates around countershaft, normally drives the wheel operation.

Compared with prior art, its advantage is this utility model electric pedal dual-purpose bicycle, can electric operation, again can The foot-operated use is not subjected to the impact of electromagnetism reaction force, is the technology of a Nover practical in fact, and this technology can be used at DC brush On the motor, also can be used on the DC Brushless Motor.

Claims
