Abstract

The utility model relates to an energy saving power-assisted bicycle, which is equipped with a friction drive mechanism, an energy storage mechanism and a power assisted mechanism, the energy which is consumed in a break process is delivered to the energy storage mechanism which is arranged on a portion of a middle shaft of the bicycle through a friction wheel, and the energy is stored through an energy storage coil spring. When needing to assist the power, the energy storage coil spring releases the stored energy to act on the middle shaft of the bicycle, thereby driving the middle shaft of the bicycle to rotate, and being used to the power-assisted when riding. The utility model has the advantages of compact structure, convenient operation, energy saving and labor saving.

Description

The energy-saving power-boost bicycle

The utility model belongs to technical field of bicycles, relates in particular to a kind of morpet.

Bicycle through regular meeting's apply the brakes, for example when descending maybe needs to slow down, after brake, when continuing to advance, needs just can make it reach original speed with the bigger power of pedaling in the process of riding.In brake process, reduced the speed of a motor vehicle, also consumed more kinetic energy simultaneously, this part kinetic energy that how will consume stores, and when treating to recover to advance after brake finishes, is used for the power-assisted to bicycle, is the problem that existing bicycle is generally ignored.

The purpose of this utility model is to disclose a kind of energy-saving power-boost bicycle, and it can be used for the kinetic energy that brake consumes the power-assisted of bicycle and travel.

For achieving the above object, adopt following technical scheme; The energy-saving power-boost bicycle has been set up slip gear, stored energy mechanism and servomechanism on the basis of existing bicycle.

Slip gear is made up of friction wheel axle, a cover for seat flexible drive axle, and friction wheel axle is supported by a cover for seat, an end can with trailing wheel wipe contact, other end connection flexible drive axle.Stored energy mechanism is made up of worm screw, worm gear, energy storage disc spring, power-assisted dish, housing, and flexible drive axle connects worm screw, and worm gear is meshed with worm screw, housing is fixed in bicycle middle shaft and puts, worm gear is contained on the interior bicycle middle shaft of housing, the inner worm gear that connects of energy storage disc spring, and the outer end connects the power-assisted dish.Servomechanism is made up of overriding clutch, brake band, the backguy of power-assisted handle, power-assisted handle, the overriding clutch inner ring is fixed on the bicycle middle shaft, its outer ring connects power-assisted dish, brake band parcel power-assisted dish outer ring, one end coupling housing, the other end is connected by the degree of tightness of stage clip control brake band and with the backguy of power-assisted handle.Propping up cover for seat is controlled by flexible pull wire by roller.

Below in conjunction with the embodiment accompanying drawing the utility model is described in detail.

Fig. 1 is the external structure scheme drawing of energy-saving power-boost bicycle.

Fig. 2 be among Fig. 1 A-A to the sectional structure scheme drawing.

Fig. 3 be among Fig. 2 B-B to cutaway view.

Fig. 4 be among Fig. 2 C-C to cutaway view.

By Fig. 1 .2, the energy-saving power-boost bicycle is made up of slip gear, stored energy mechanism and servomechanism three parts.Slip gear props up cover for seat 2, bearing pin 3 by friction wheel axle 1, torsion spring 4, flexible drive axle 5, roller 6, flexible pull wire 7 is formed, prop up cover for seat 2 and link by bearing pin 3 and vehicle frame, torsion spring 4 is arranged on the bearing pin 3, torsion spring 4 one ends are fixed on the vehicle frame, the other end is fixed on the cover for seat 2, friction wheel axle 1 is contained on the cover for seat 2, and the one end is a friction wheel, the other end with connect with flexible drive axle 5.Roller 6 is contained on the vehicle frame, and flexible pull wire 7 one ends are fixedly connected with a cover for seat 2, walks around roller 6 other ends and links with back brake backguy.

By Fig. 2,3,4, stored energy mechanism is by worm screw 16, worm gear 17, and energy storage disc spring 11, power-assisted dish 9, housing 10 is formed.Flexible drive axle 5 connects worm screw 16, and worm gear 17 is meshed with worm screw 16, and housing 10 is fixed in bicycle middle shaft and puts outward, and worm gear 17 is contained on the interior bicycle middle shaft of housing, and energy storage disc spring 11 1 ends and worm gear 17 are fixedly connected, and the other end connects with power-assisted dish 9.

By Fig. 2,4, servomechanism is by overriding clutch 8, brake band 12, power-assisted handle backguy 13, power-assisted handle 18, adjustable bolt 15, stage clip 14 is formed, and overriding clutch 8 inner rings are fixed on the bicycle middle shaft, and power-assisted dish 9 links with the overriding clutch outer ring, brake band 12 parcel power-assisted dishes 9 outer rings, brake band 12 1 ends and housing 10 link, the other end and adjustable bolt 15, stage clip 14, brake backguy 13 links, and to adjust the tightness of brake band, power-assisted handle 18 is contained on the handle grip for bicycle.

The working process of energy-saving power-boost bicycle is as follows: when bicycle when descending maybe need slow down, brake after the pinching, the flexible pull wire tension that links to each other with back brake backguy, flexible pull wire is walked around roller, will prop up the cover for seat pulling, and making it with bearing pin 3 is that rotate at the center, be contained in friction wheel axle that bearing puts this moment near bicycle rear, the rotating band dynamic friction wheel shaft of trailing wheel rotates, and by flexible drive axle worm screw is rotated, and then drives the worm gear rotation.When pinching the back brake, the power-assisted handle loosens, and at this moment, under the effect of stage clip 14, makes brake band wrap tightly power-assisted dish outer ring, causes the power-assisted dish not rotate in certain friction force scope, and the big I of friction force is regulated by adjustable bolt.At this moment, under the drive of worm gear, the energy storage disc spring coils, thereby energy storage is got up, and arrives to a certain degree, and limited because of the friction force of brake band, power-assisted dish and brake band slide, and the energy storage disc spring no longer coils, and thermal energy storage process finishes.When unclamping the back brake, flexible pull wire is loosened, and bearing is enclosed within the effect of torsion spring, and friction wheel axle and back wheels of vehicle are broken away from, and stored energy mechanism stops energy storage.

When needing power-assisted, rotate the power-assisted handle, brake band is loosened, because the back brake is in releasing orientation, worm gear, worm screw are no longer rotated, thereby make in the energy storage disc spring

End maintains static, and the disc spring under the coiled state will drive the power-assisted dish and rotate, and is logical

Cross overriding clutch, transfer torque on the bicycle middle shaft, and then drive the chain drum rotation, finish the power-assisted process with foot-operated the cooperation.The length of power-assisted time, torque can be by rotating the power-assisted handle, and the size of regulating friction force between brake band and the power-assisted dish realizes.When not needing power-assisted at ordinary times, the power-assisted handle loosens, because the structure of overriding clutch makes energy-conservation servomechanism not influence the cruising of bicycle itself.

Compared with prior art, have the following advantages:

1, compact conformation, easy to operate.

Energy-conservation when 2, riding, laborsaving.
