Abstract

The utility model discloses a bicycle with spare supporting wheels, which comprises a front wheel and a rear wheel, wherein the two sides of the rear wheel are respectively provided with a spare small wheel 1 and a spare small wheel 2, the spare small wheel 1 and the spare small wheel 2 have two states of use and spare, in the use state, the spare small wheel 1 and the spare small wheel 2 are simultaneously contacted with the ground, and the radial distance from the contact points of the spare small wheels and the ground to a rear axle is slightly larger than or equals to that from the contact point of the rear wheel and the ground to the rear axle; and when the spare small wheel 1 and the spare small wheel 2 are in the spare state, the spare small wheel 1 and the spare small wheel 2 are not contacted with the ground. When a tire is damaged, a spare tire can be used, so the bicycle can be pushed to travel, the bicycle is more labor saving, the damaged tire can also be protected, and the bicycle is particularly suitable for electric bicycles.

Description

A kind of bicycle of preparing and carrying with support wheel

Technical field

The utility model relates to the Electrical Bicycle field, especially relates to a kind of bicycle of preparing and carrying with support wheel.

Background technology

The battery-driven car of environmental protection is because rapid speed, climb and ride laborsaving, increasingly liked by everybody; But the cyclist ran into tire is pricked the logical situation that does not have gas, because the battery-driven car vehicle body is heavier relatively, storage battery is also heavier; In case run into this situation; Carry out repairing a little very time-consuming and effort, also damaged more serious of tire, even can not re-use.

Summary of the invention

The goal of the invention of the utility model provides a kind of bicycle of preparing and carrying with support wheel, after tire damages, can use spare tire, and bicycle is shoved along, and is more laborsaving, also can protect the tire of damage, more obvious for the effect of Electrical Bicycle.

For realizing the goal of the invention of the utility model, adopted following technical scheme:

This bicycle of preparing and carrying with support wheel; Comprise front-wheel, trailing wheel; Subsequent use steamboat one and subsequent use steamboat two are set respectively in the trailing wheel both sides, and subsequent use steamboat one is in subsequent use steamboat two and uses and subsequent use two states, when being in running condition; Subsequent use steamboat one contacts with ground with subsequent use steamboat two simultaneously, and the radial distance of its contact point to hind axle is slightly larger than or equals the radial distance of trailing wheel and ground contact point to hind axle; When subsequent use steamboat one is in stand-by state with subsequent use steamboat two, subsequent use steamboat one and subsequent use steamboat two and ground noncontact.

Additional technical feature is, subsequent use steamboat one, subsequent use steamboat two are connected with rear axle with connecting rod two through connecting rod one respectively.

Additional technical feature is; Subsequent use steamboat three and subsequent use steamboat four are set respectively in the front-wheel both sides; Subsequent use steamboat three, subsequent use steamboat four are connected with the front-wheel wheel shaft with connecting rod four through connecting rod three respectively, and subsequent use steamboat three and subsequent use steamboat are everywhere in use and subsequent use two states, when being in running condition; Subsequent use steamboat three contacts with ground with subsequent use steamboat four simultaneously, and the radial distance of its contact point to front wheel spindle is slightly larger than or equals the radial distance of front-wheel and ground contact point to front wheel spindle; Subsequent use steamboat three and subsequent use steamboat everywhere when stand-by state, subsequent use steamboat three and subsequent use steamboat four and ground noncontact.

The beneficial effect of the utility model is, adopts the structure of subsequent use steamboat, after tire damages, launches subsequent use steamboat, and subsequent use steamboat contacts with ground, supports the tire of damage, when shoving along bicycle, and can be laborsaving; The tire that damages is owing to supported by steamboat, the force of gravity of bicycle to steamboat, thereby can protect the tire of damage, more outstanding for bicycle such as Electrical Bicycle beneficial effect that weight is heavier.

Adopt the additional technical feature of the utility model, subsequent use steamboat one, subsequent use steamboat two are connected with connecting rod two and trailing wheel are coaxial through connecting rod one respectively, have simplified structure, the technique effect that is easy to assemble.

Adopt the additional technical feature of the utility model, subsequent use steamboat is set respectively, when the front-wheel of Electrical Bicycle damages, also can play the effect of the front tyre that laborsaving and protection damage when shoving along Electrical Bicycle in the front-wheel both sides.

Description of drawings

Structural representation when Fig. 1 is in stand-by state for the subsequent use steamboat of the utility model.

Structural representation when Fig. 2 is in running condition for the subsequent use steamboat of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing 1 and accompanying drawing 2, the utility model is done concrete description.

This bicycle of preparing and carrying with support wheel during enforcement; Comprise front-wheel 1, trailing wheel 2; Subsequent use steamboat 3 and subsequent use steamboat 4 are set respectively in trailing wheel 2 both sides; The both sides that subsequent use steamboat 3 and subsequent use steamboat 4 are arranged at trailing wheel 2 symmetrically help balance when using like this, and subsequent use steamboat 3 is connected with rear axle 7 through connecting rod 5, and same subsequent use steamboat 4 also passes through a connecting rod and is connected with rear axle.Subsequent use steamboat 3 has two kinds of uses and subsequent use two states with subsequent use steamboat 4; When trailing wheel 1 damages; Or when not having gas, subsequent use steamboat 3 being arranged at running condition with subsequent use steamboat 4, subsequent use steamboat 3 contacted with ground with subsequent use 4 whiles of steamboat; The radial distance of its contact point to hind axle 7 is slightly larger than or equals the radial distance of trailing wheel and ground contact point to hind axle 7, and the gravity of Electrical Bicycle will be transferred on the subsequent use steamboat from trailing wheel 2; When trailing wheel normally uses, when not damaging, subsequent use steamboat 3 is in stand-by state with subsequent use steamboat 4, subsequent use steamboat 3 and subsequent use steamboat 4 and ground noncontact.

Although in the accompanying drawing for drawing; But clearly, the both sides of front-wheel 1 also in like manner can be provided with two subsequent use steamboats respectively, are referred to as subsequent use steamboat three and subsequent use steamboat four here; Subsequent use steamboat three, subsequent use steamboat four are connected with front-wheel wheel shaft 6 through connecting rod respectively; Subsequent use steamboat three also has use and subsequent use two states with subsequent use steamboat four, when front-wheel 1 damages or do not have gas, subsequent use steamboat three, four is arranged at running condition; Subsequent use steamboat three contacts with ground with subsequent use steamboat four simultaneously, and the radial distance of its contact point to front wheel spindle 6 is slightly larger than or equals the radial distance of front-wheel and ground contact point to front wheel spindle 6; When front-wheel 1 normal the use, subsequent use steamboat three is arranged at stand-by state with subsequent use steamboat four, subsequent use steamboat three and subsequent use steamboat four and ground noncontact.

Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Other modifications that those of ordinary skills make the technical scheme of the utility model perhaps are equal to replacement; Only otherwise break away from the spirit and the scope of the utility model technical scheme, all should be encompassed in the middle of the claim scope of the utility model.
