Abstract

A mountain electric bicycle has high output torque, strong climbing capacity and simple structure, and modifies the bicycle mechanical structure in prior art and is additionally assembled with an electric transmission system; a drawer-type battery case with a rechargeable battery case and a lock buckle is welded on the lower side of a bicycle rear support shelf, the cylindrical sleeve of a speed regulation dc motor is arranged in the middle of a cushion diagonal bar and is integrally welded with the cushion diagonal bar along the parallel direction of a wheel shaft; six adjusting stopper screws divided into two groups are arranged on the cylindrical sleeve along the outer circumference with interval of 120 degrees, a small wheel chain on the output shaft end of a speed regulation dc motor is connected with a large chain wheel with a flywheel and arranged on a rear wheel shaft of the bicycle together to form a speed reduction transmission mechanism; a motor electric control box is mounted between the lower side of the cushion diagonal bar and the upper side of the cylindrical sleeve of the speed regulation dc motor.

Description

The mountain region Electrical Bicycle

Technical field

The utility model relates to a kind of physical construction and driving device of Electrical Bicycle.

Background technology

At present existing electric bicycle structure complexity, driving torque is little, hill climbing ability is weak, can only be at more smooth road traveling, the defective that can not conveniently travel at high gradient road surface, road surface, mountain region and various complex road surface.

Summary of the invention

For overcome and improve that existing electric bicycle structure complexity, driving torque are little, a little less than the hill climbing ability, can only be at more smooth road traveling, the deficiency that can not conveniently travel at high gradient road surface, road surface, mountain region and various complex road surface, the utility model provides a kind of physical construction and driving device of bicycle, thereby reach that electric bicycle structure is simple, assembling easily, driving torque is big, hill climbing ability is strong, the purpose that can conveniently travel at high gradient road surface, road surface, mountain region and various complex road surface.

The technical scheme that its technical matters that solves the utility model adopts is:

The drawer type battery box is welded on below the bicycle rear goods bracing frame of repacking, and charging battery cartridge is housed in the drawer type battery box, and can pack into easily, takes out and pin; Be enclosed within cylinder sleeve on the electrical motor along the outer 120 degree location of equal be equipped with three two groups totally six regulate holding screws, cylinder sleeve is along axletree parallel direction, integrally welded at seat cushion hound midway location and seat cushion hound; After electrical motor embeds cylinder sleeve, the hinge wheel that has flywheel on minor sprocket on the motor and the axletree, connect by chain, regulate six adjusting fixing screws on the cylinder sleeve respectively, reach optimum position, form the Electrical Bicycle driving device axially parallel with band flywheel hinge wheel and the chain tension of electrical motor with axially parallel, the minor sprocket of wheel; Speed-governing dc electrical motor electrical equipment control capsule is installed in position between bicycle saddle cushion hound downside and the speed-governing dc motor cylinder overcoat top; Rechargeable battery adopts No. 1 standard charging battery pack of a plurality of combinations, electrical motor adopts the speed-governing dc electrical motor greater than the specified output torque of 3.5N.M, reach that electric bicycle structure is simple, assembling easily, driving torque is big, hill climbing ability is strong, can be in the mountain region the high gradient and the various complex road surface purpose of conveniently travelling.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that master of the present utility model looks, left TV structure figure.

Fig. 2 is that the master of the semi-sictional view of Fig. 1 looks, left view.

Among Fig. 1 and Fig. 2,1. the drawer type battery box, 2. charging battery cartridge, 3. drawer type battery box snap close, 4. electrical motor electrical equipment control capsule, 5. the motor cylinder overcoat, 6. the speed-governing dc electrical motor, 7. regulate holding screw, 8. electrical motor minor sprocket, 9. band flywheel hinge wheel, 10. chain.

The specific embodiment:

In Fig. 1 and Fig. 2, drawer type battery box (1) is welded on below the bicycle rear goods bracing frame of repacking, and charging battery cartridge (2) is housed in the drawer type battery box (1), can pack into easily, take out, and pins by drawer type battery box snap close (3); The motor cylinder overcoat (5) that is enclosed within on the speed-governing dc electrical motor (6) is equipped with three two groups totally six adjusting holding screws (7) along cylindrical 120 degree location of equal, motor cylinder overcoat (5) is along axletree parallel direction and integrally welded at seat cushion hound midway location and seat cushion hound, after speed-governing dc electrical motor (6) embeds motor cylinder overcoat (5), the hinge wheel (9) that has flywheel on electrical motor minor sprocket (8) on the speed-governing dc electrical motor (6) and the axletree, connect by chain (10), regulate holding screw (7) for six that regulate respectively on the cylinder sleeve, reach axially parallel the axial and wheel of speed-governing dc electrical motor (6), minor sprocket (8) and the parallel and slack-free optimum position of chain (10) of band flywheel hinge wheel (9).

Claims
