Abstract

The utility model provides the electrically driving apparatus of a bicycle, comprising a power supply, a control switch connected with the output line of the power supply, an electric motor connected with the other output line of the power supply, a drive mechanism and a drive shaft installed on a supporting frame; besides, the electric motor controlled by a control switch is arranged on the supporting frame. The drive mechanism comprises a driving gear arranged on the output shaft of the electric motor, a drive sprocket, a driven gear which is arranged on the drive shaft and is engaged with the driving gear, and a driven sprocket which is connected with the drive sprocket through chains and can be rigidly connected to the sheath of the rear wheel spindle of the bicycle. The utility model which has the advantages of simple structure, low cost and convenient operation can be installed on the common bicycle, and the common bicycle can be changed to an electric bicycle.

Description

Electrically driving apparatus of bicycle

The utility model relates to a kind of and the supporting bicycle electric driver of ordinary bicycle.

Electric bicycle structure complexity, the cost height sold on the present China market, difficulty of processing is big, is not suitable for promoting.

The purpose of this utility model be for provide a kind of simple in structure, cost is low, can with the supporting bicycle electric driver of ordinary bicycle.

The utility model comprises power supply, with power supply output line bonded assembly master cock, bracing frame, the electrical motor on the bracing frame of being contained in the control of another output line bonded assembly suspension control switch of power supply, transmission device, be contained in the transmission shaft on the bracing frame, transmission device comprises the driving gear that is contained on the motor output shaft, be contained on the transmission shaft with driving gear ingear driven gear, be contained in the drive sprocket on the transmission shaft, can be contained in driven sprocket on the bicycle rear shaft skin rigidly (referring to Fig. 1 by chain and drive sprocket bonded assembly, Fig. 2, Fig. 3, Fig. 4), when need are electronic after being installed in the utility model on the ordinary bicycle, open master cock, thereby electrical motor rotate to drive driving gear and rotates power warp and driving gear ingear driven gear passed to motor output shaft and drive the drive sprocket rotation on the transmission shaft, drive sprocket rotates by chain power to be passed to driven sprocket is rotated the bicycle rear shaft skin that is connected as a single entity is with it rotated again trailing wheel is rotated, and is simple in structure.

The utility model is simple in structure, cost is low, can be installed on the ordinary bicycle, the performance that makes it to become Electrical Bicycle and do not influence former bicycle, easy to use, particularly allow long-distance people by bike on and off duty or tourism, from spirit to muscle power, all be loosened, recover.For beautify life, increase work efficiency and play positive role.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

The utility model comprises the storage battery 2 that is contained in the battery case 1, with 2 one output line bonded assemblys of storage battery master cock 3, bracing frame 4, with the electrical motor 5 in the bracing frame 4 of being contained in of another output line bonded assembly suspension control switches 3 controls of storage battery 2, transmission device 6 is contained in the transmission shaft 7 on the bracing frame 4.Transmission device 6 comprises the driving gear 8 that is contained on electrical motor 5 output shafts, be contained on the transmission shaft 7 with driving gear 8 ingear driven gears 9, be contained in the drive sprocket 10 on the transmission shaft 7.By chain 11 and drive sprocket 10 bonded assembly driven sprockets 12.Driven sprocket 12 is rigidly connected on the bicycle rear shaft skin 13.

The utility model is installed on bicycle the time, available framework 14 is installed in (referring to Fig. 1) on the bicycle tripod with battery case 1.With master cock fixed card 15 master cock 3 is installed in handle-bar left hand place (referring to Fig. 1, Fig. 5), the unlatching that the control key on it can be controlled power supply can be controlled the horsepower output of power supply again, thus the may command speed of a motor vehicle.Link gear 16 is installed on master cock 3.Link gear 16 comprises and handle-bar parking brake 17 bonded assemblys outage pin 18, on the master cock 3 with on outage pin 18 relative positions outage pin pipe 19 of being with micro-switch is being housed.When meeting emergency situation, gently shake hands and stop, the micro-switch in the outage pin 18 contact electricity untie-sell pipes 19 makes power cut-off and car is easy to check.

Bracing frame 4 one ends that electrical motor 5 is housed are fixed on the rear bicycle, and the other end is equipped with left and right sides support tube 20,21.The other end of left and right

sides support tube

20,21 is fixed on (referring to Fig. 1, Fig. 4) on the bicycle rear axle.Left and right

sides support tube

20,21 is made up of the upper support pipe 23 that a lower support pipe 22 and an end stretch in the lower support pipe 22 respectively, has several grooves in lower support pipe 22 and upper support pipe 23 contact portions.Left and right

sides support tube

20,21 can be regulated its length according to the bicycle model, tightens up with fastening card 24 then.

Drive sprocket 10, chain 11, driven sprocket 12 are contained in the chain cover 25.Chain cover 25 1 ends are contained on the bracing frame 4, and the other end is contained on the bicycle rear shaft.Chain cover 25 is made up of the last chain covers 27 that following chain cover 26, an end can insert down in the chain cover 26, both is close to (referring to Fig. 2) with screw 28.Can regulate chain cover 25 length according to the bicycle model.

When electrical motor 5 rotated, the driving gear 8 on it drove driven gear 9, rev down.Drive sprocket 10 rotates simultaneously and drives chain 11 and drive driven sprocket 12, and driven sprocket 12 is to be contained in rigidly on the bicycle rear shaft skin 13, drives hind axle trailing wheel is rotated, thereby drives bicycle running.

Actuating motor 5, and bicycle is still ridden as ordinary bicycle.
