Abstract
The invention belongs to the field of bicycle structures, and particularly relates to an electric telescopic bicycle. The bicycle comprises an electric telescopic frame, a steering mechanism, wheels, a power system and a brake system, when in contraction, a motor is started, the motor drives a small gear to rotate, and a lead screw is driven to move downwards through a big gear, thereby enabling a front rod, a rear rod, a front fork and a rear fork to close up to the direction of the lead screw and simultaneously folding pedal plates; after the lead screw moves to the lower limit, the motor stops working; the upper half part of the steering mechanism is folded backwards manually, and a handlebar is further folded for completing the whole contraction process; and the expansion process is contrary to the contraction process. The bicycle can expand or contract automatically within 5-10 seconds, and the operation is simple and convenient; the expansion degree of the bicycle is controllable, a user can regulate the height and the length of the bicycle according to the needs of the user, and the self-locking can be performed in any position; and the bicycle after contraction is in a hexahedron-like structure, the occupied area is small, and the bicycle can be placed in a luggage case, thereby being very convenient to carry and store.
Description
Technical field
The invention belongs to the bicycle structure field, particularly a kind of electric telescopic bicycle.
Background technology
Bicycle is a kind of easily vehicle, but because the structure problem of himself often can run into and stop problem inconvenient, that be difficult to carry, easily stolen risk is arranged especially.And it is parked in indoor, can take larger space again.
For addressing this problem, Collapsible bicycle has appearred on the market, and take up an area little after folding and be convenient for carrying.But Collapsible bicycle needs manual operation, and is provided with a lot of locking fixed mechanisms in folding and unfolding process, and this is for the user who does not much understand physical construction, and inconvenience.Sometimes unfold not in placely, also may cause potential safety hazard.And the unfolding degree of existing Collapsible bicycle is fixing uncontrollable, and the bicyclist that can not be fit to all statures uses.
Summary of the invention
The invention provides the deficiency for existing folding bicycle, a kind of electric folding bicycle simple in structure, easy to use is provided.
The technical solution used in the present invention is:
This electric telescopic bicycle, but several parts of vehicle frame, steering hardware, wheel, power system and brake system that comprise electric expansion, wherein, but the structure of the vehicle frame of agent structure electric expansion be: the rear and front end of crossbeam is connected by rotating shaft with back vent with front fork respectively; The middle part of crossbeam arranges big gear wheel; The inner ring of big gear wheel is helicitic texture, cooperates with the leading screw of vertical placement, and the outer ring of big gear wheel and pinion, motor is installed in the below of crossbeam, and its mouth is connected with miniature gears; Captive joint with the upper end of vertical king-rod in the lower end of leading screw, the lower end of king-rod is connected by rotating shaft with rear bar with front bar and is connected; The front end of front bar and front fork middle part is connected by revolute pair, and is connected by revolute pair with steering hardware after passing groove in the middle part of the front fork, and the rear end of rear bar is connected by revolute pair with the middle part of back vent.
The top of described leading screw arranges vehicle seat, and the bottom of vehicle seat arranges the slide bar with the crossbeam bearing fit.
The equal in length of described front fork and back vent.
Part on the described front bar between from the front fork to the king-rod and the equal in length of rear bar.
The mid point of the some position front fork that described front bar and front fork intersect; The mid point of the some position back vent that described rear bar and back vent intersect.
The end of described front fork connects front-wheel, and the end of back vent connects trailing wheel.
Drive motor and brake system are installed in the described trailing wheel.
The first half of described steering hardware can be folding along fore-and-aft direction; The top of steering hardware is the left and right sides handlebar that can inwardly fold.
Advantage of the present invention is: this bicycle can be launched or contraction in second at 5-10 voluntarily by motor-driven, and is simple to operation, is fit to everyone and uses; The degree that bicycle launches is controlled, and the user can be according to height and the length of own demand adjusting bicycle, and at an arbitrary position self-locking; Bicycle after the contraction is approximate hexahedron structure, and floor area is little, can put into baggage container, and it is very convenient to carry and deposit.

The specific embodiment
The invention provides a kind of electric telescopic bicycle, the present invention will be further described below in conjunction with the drawings and specific embodiments.
Such as Fig. 1-shown in Figure 4, but this bicycle comprises several parts of vehicle frame, steering hardware, wheel, power system and brake system of electric expansion.Wherein, but the structure of the vehicle frame of electric expansion be: are connected with back vent with front fork 2 respectively and are connected by rotating shaft in the rear and front end of crossbeam 1; The middle part of crossbeam 1 arranges big gear wheel 4; The inner ring of big gear wheel 4 is helicitic texture, cooperates with the leading screw 5 of vertical placement, and the outer ring of big gear wheel 4 and miniature gears 6 engagements, motor 7 is installed in the below of crossbeam 1, and its mouth is connected with miniature gears 6; Captive joint with the upper end of vertical king-rod 8 in the lower end of leading screw 5, the lower end of king-rod 8 and front bar 9 are connected with rear bar and are connected by rotating shaft respectively; The top of leading screw 5 arranges vehicle seat 11, and the bottom of vehicle seat 11 arranges the slide bar 12 with crossbeam 1 bearing fit.The front end of front bar 9 is connected by revolute pair with front fork 2 middle parts, and is connected by revolute pair with steering hardware after passing the groove at front fork 2 middle parts, and the rear end of rear bar 10 is connected by revolute pair with the middle part of back vent 3.
Wherein, the equal in length of front fork 2 and back vent 3; Part on the front bar 9 between from the front fork to the king-rod and the equal in length of rear bar 10; The mid point of the some position front fork 2 that front bar 9 and front fork 2 intersect; The mid point of the some position back vent 3 that described rear bar 10 and back vent 3 intersect.
The end of front fork 2 connects front-wheel 13, and the end of back vent 3 connects trailing wheel 14.In trailing wheel 14 interior installation drive motor and brake system, storage battery is arranged in the hole of back vent 3.In front bar 9 folding pedal 16 is installed.The first half of steering hardware 15 can be folding along fore-and-aft direction; The top of steering hardware is the left and right sides handlebar 17 that can inwardly fold.
During contraction, open motor 7, motor 7 Drive pinions 6 rotate, and then drive leading screw 5 by big gear wheel 4 and move down, and front bar 9, rear bar 10, front fork 2 and back vent 3 are all drawn close to leading screw 5 directions.After leading screw 5 moved to the lowest limit, motor 7 quit work; Pedal 16 is packed up, and the first half of steering hardware 15 is folded back, and Foldable handlebar 17, namely finishes whole contraction process.It is little that bicycle after the contraction takes up an area the space, is easy to carry about with one and deposits, such as Fig. 5-shown in Figure 8.
Expansion process is opposite with contraction process, and at any time can shut-down operation in the expansion process, and all can be in the lock state at an arbitrary position, in order to regulate length and the height of bicycle.
