Description

Bicycle booster

Technical Field

The utility model relates to a bicycle technical field especially relates to a bicycle booster unit.

Background

Bicycles, also known as bicycles or bicycles, are typically two-wheeled small land vehicles. After a person rides the vehicle, the person steps on the pedal as power, and the vehicle is a green and environment-friendly vehicle.

The current children bicycle can install the auxiliary wheel on the car rear wheel usually for supplementary children ride, but children bicycle speed of a motor vehicle can't be adjusted, and children need be the automobile body through the manual brake and slow down, and during children's bicycle of first learning, unable accurate judgement car condition leads to the speed of a motor vehicle to cause children's bodily injury when very fast easily.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a bicycle power assisting device.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a bicycle booster unit, booster unit installs in the bicycle back vent and the rear wheel outside, and booster unit includes the elastic rod of two arc structures, and two the fixed disk has all been welded at the top of elastic rod, and the installation piece has all been welded to the bottom of two elastic rods, fixed disk, bicycle back vent and rear wheel are through same root wheel axle, are equipped with the gasket that cup joints in the wheel epaxial between fixed disk and the bicycle back vent, two the axle center position department of installation piece is connected with the transfer line through the bearing, and the middle part of transfer line is pegged graft and is had the drive wheel, the wheel groove of loop configuration is seted up at the middle part of drive wheel outer wall, and wheel inslot wall and rear wheel form interference fit, the both ends of transfer line all are fixed with the.

Preferably, the fixed disc, the elastic rod and the mounting piece are of an integrated structure.

Preferably, the inner wall of the wheel groove is provided with anti-skid threads.

Preferably, the vertical section of the middle part of the transmission rod is of a square or regular hexagon structure, and nuts are screwed at two ends of the transmission rod and two ends of the wheel shaft.

The utility model has the advantages that:

the utility model discloses in, through with back wheel joint in the wheel inslot of drive wheel, avoid the direct and ground contact of back wheel, drive transfer line and auxiliary wheel rotation through the frictional force between back wheel and the drive wheel, reduced the speed of riding of automobile body, avoid the child's bike because of the speed of a motor vehicle is too fast to meet accident, and treat that children are familiar with the speed of car condition after the removable drive wheel, increase the speed of automobile body.

Drawings

Fig. 1 is a schematic view of an installation structure of a bicycle power assisting device provided by the present invention;

fig. 2 is a rear view schematic diagram of the power assisting device for a bicycle provided by the present invention.

In the figure: 1 bicycle rear fork, 2 rear wheels, 3 wheel axles, 4 gaskets, 5 fixed discs, 6 elastic rods, 7 mounting pieces, 8 transmission rods, 9 transmission wheels, 10 wheel grooves and 11 auxiliary wheels.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a bicycle booster is provided, the booster is installed at the outer sides of a bicycle rear fork 1 and a rear wheel 2, the booster includes two elastic rods 6 with arc structures, a fixed disk 5 is welded at the tops of the two elastic rods 6, mounting plates 7 are welded at the bottoms of the two elastic rods 6, the fixed disk 5 is used for enabling the bicycle rear fork 1 and the rear wheel 2 to pass through a same wheel axle 3, a gasket 4 sleeved on the wheel axle 3 is arranged between the fixed disk 5 and the bicycle rear fork 1, the axle center positions of the two mounting plates 7 are connected with a transmission rod 8 through bearings, a transmission wheel 9 is inserted in the middle of the transmission rod 8, a wheel groove 10 with an annular structure is formed in the middle of the outer wall of the transmission wheel 9, the inner wall of the wheel groove 10 forms interference fit with the rear wheel 2, and auxiliary wheels 11 are fixed.

The utility model discloses in, fixed disk 5, elastic rod 6 and installation piece 7 formula structure as an organic whole have seted up anti-skidding screw thread on the inner wall of wheel groove 10, and the middle part vertical cross-section of transfer line 8 is square or regular hexagon structure, and the equal spiro union in both ends of transfer line 8 and axletree 3 has the nut.
