Abstract

The utility model discloses a folding electric bicycle which comprises a connecting frame, a front bicycle frame, a rear bicycle frame, a positioning group, a connecting rod and a supporting group, wherein, the front bicycle frame and the rear bicycle frame are respectively arranged at both ends of the connecting frame, wherein, the front and the rear bicycle frames are respectively provided with a front and a rear wheels; a supporting shaft is pivoted between the connecting frame and the front bicycle frame; the supporting group is pivoted between the connecting frame and the rear bicycle frame. The rear bicycle frame relative to the front bicycle frame is inwards moved by using the positioning group as a fulcrum through the control of the positioning group, and accordingly, the rear bicycle frame can be moved between an unfolded position and a folded device. In order to realize that the electric bicycle can reduce resistance force in a folded state and the front and the rear wheels are easy to move, the electric bicycle also comprises a supporting auxiliary wheel which is pivoted with object placing boxes which are arranged at both sides of the rear wheel. When the rear bicycle frame is in a folded position, the rear bicycle frame and the rear wheel are arranged at the same horizontal face and synchronously contact the ground by the supporting auxiliary wheel, and thus, the electric bicycle achieves the aim for stabilizing a bicycle body during folding, positioning and movement.

Description

The convertible electric bicycle

Technical field

The utility model relates to a kind of convertible electric bicycle, it is less and the electric bicycle that supports auxiliary wheel is installed to be particularly related to a kind of overall space volume after folding, this electric bicycle can reduce electric bicycle occupied space usually, so that transport and fold the location, and when moving, it can stablize vehicle body.

Background technology

The handle bridge and one that the front and back wheel, that general electric bicycle all has a vehicle frame, be located at the vehicle frame front and back end respectively is hubbed at vehicle frame front end and may command front-wheel steering is assembled in the sprocket drive between vehicle frame and the trailing wheel, rotate with the trailing wheel that drives electric bicycle by driver train, and then reach the purpose of electric bicycle reach, that this kind electric bicycle has is light, easy to use, inexpensive, and advantage such as discharging waste gas not, therefore, electric bicycle occupies a tiny space in the social now vehicle.

But above-mentioned electric bicycle is fixed owing to its vehicle frame, in collection, take up space, therefore, in order to adapt to the narrow and small problem in modern living space, just occurred a kind of before, the collapsible electric bicycle that folds of back vehicle frame, its rough structure as shown in Figure 1, this electric bicycle A1 comprises a vehicle frame A11, be assembled in a cooresponding front-wheel A12 in vehicle frame A11 bottom and front and back and a trailing wheel A13 respectively, one is located at the cushion A14 on vehicle frame A11 top, an and handlebar stem A15 who is installed in vehicle frame A11 the place ahead and may command direction, wherein, this vehicle frame A11 have one be positioned at before, trailing wheel A12, attaching parts A16 between the A13, and in order to make vehicle frame A11 collapsible, this attaching parts A16 is made of a preceding bar A161 that can dock and a back bar A162, before butt joint, back bar A161, be assembled with a fold mechanism A17 between the A162.

Can make this electric bicycle A1 reach the folding state that folds by controlling this fold mechanism A17, as shown in Figure 1, existing convertible electric bicycle A1 is by forward and backward bar A161, the folding design of A162 of attaching parts A16, really can make the overall space smaller volume of electric bicycle A1 after folding, thereby the purpose that reach convenient collection, does not take up space, but this kind folds the only length over ends of body of folding electric bicycle A1 of mode, it is shored, the seat pipe of cushion A14 and can't folding, still takes up room; In addition, after electric bicycle A1 is folding, when it is moved, A12 relies on trailing wheel A13 because of its front-wheel, at this moment, trailing wheel A13 and front-wheel A12 be butt mutually, and two axles can stagger mutually and make outstanding the stretching in the front-wheel A12 of wheel shaft of trailing wheel A13, cause electric bicycle A1 can't reach the purpose that moves easily, have only the whole ground that is lifted away from of electric bicycle A1 just can be moved again, cause the inconvenience of moving after rider's folding by the drive of wheel, require great effort, therefore, described electric bicycle A1 being had does not take up space, and can install advantages such as location after folding, be the technical matters that will solve of the present utility model.

The utility model content

So, the purpose of this utility model is to provide a kind of less and electric bicycle of back overall space volume of amounting to when folding folded state, can be by the location group between a link span and the back vehicle frame, and be fulcrum with this location group, forward and backward vehicle frame is moved between an expanded position and a stowed position.

Convertible electric bicycle of the present utility model, comprise a link span, be located at a front vehicle frame, a back vehicle frame at link span two ends respectively, one is hubbed on the fulcrum between link span and the front vehicle frame, one is hubbed on the location group between link span and the back vehicle frame, and the auxiliary wheel of a support group, wherein, the front and back vehicle frame has a front and back wheel respectively.

Back of the present utility model vehicle frame can move between an expanded position and a stowed position by the control of location group, when the back vehicle frame is positioned at expanded position, the trailing wheel of this back vehicle frame is away from the front-wheel of front vehicle frame, and when the back vehicle frame is positioned at stowed position, promptly the back vehicle frame is that the relative link span of fulcrum revolves when moving with the fulcrum of location group, and the trailing wheel of back vehicle frame is distinguished mobile to the inside with the front-wheel of front vehicle frame; In addition, electric bicycle comprises that also one is installed in the support group on the back vehicle frame, and this support group has one and is articulated in the support auxiliary wheel of the storage box of the trailing wheel both sides of vehicle frame afterwards.Vehicle frame is positioned at when strutting the position when the back, support not kiss the earth of auxiliary wheel, and be positioned at when amounting to the position when the back vehicle frame, support auxiliary wheel and be positioned at the also synchronous kiss the earth of same horizontal surface with trailing wheel, amount to the location, back with auxiliary electric bicycle, and when mobile, stablizing vehicle body.
