Abstract

The invention discloses a folding vehicle which comprises a front frame and a rear frame, a front wheel, a rear wheel, an electric driving device, wherein the front part of the front frame is provided with the front wheel, and the rear part of the rear frame is provided with the rear wheel; and a folding structure which has one shaft and two wings, can rotate around the shaft, is folded by arching and is similar to a hinge is arranged between the front frame and the rear frame. The folding vehicle is characterized by further comprising a folding and unfolding suspension support structure. Due to the improvement, the folding vehicle greatly reduces the space occupied by the vehicle when in parking, and has reliable and stable vehicle traveling dynamic stabilization with large span and low center of gravity when being unfolded for driving.

Description

A kind of folded bicycle

Technical field:

The present invention relates to a kind of telescopic folding car of variable-volume, especially a kind of electronic riding light-duty telescopic folding car.

Background technology:

Now the big city is because the anxiety on land for building and price surging, and the parking stall is in state more and more in short supply, and therefore effectively reducing the parking area occupied is one of direction of vehicle design, and the expansion and contraction of retractable vehicle requires more and more higher.Simultaneously, because the minimizing day by day of resources such as gasoline, the miniaturization of vehicle, lightness, motorized also are the main flow design directions.

More existing flexible vehicles, some be when launching the length between the front and back wheel not enough, cause the instability of travelling, some is the not enough end of center of gravity and the instability that causes travelling when launching, some is that to have satisfied length enough long and center of gravity is enough low, but but deficiency of load.

The present invention attempts to satisfy enough expansion and contractions simultaneously, has enough front and back wheel spans during expansion, has enough low center of gravity, also has the collapsible vehicle of above-mentioned like this four requirements of enough load-carrying capacitys simultaneously.

Summary of the invention:

The present invention discloses a kind of folded bicycle, comprise front vehicle frame, back vehicle frame, the front-wheel of front vehicle frame front portion, the trailing wheel at back vehicle frame rear portion, electric driver, front vehicle frame and back have the one two wing class hinge foldable structure that can arch upward folding that sways between the vehicle frame, its improvement is: also have this improvement of the unsettled underwork of folding and expanding, dwindled the parking area occupied of vehicle widely little, launch to have again when travelling large span, the reliable and stable vehicle ' dynamic stability of low center of gravity simultaneously.

Adopt the folded bicycle of this spline structure to solve two problems, the one, the parking area requirements is reduced greatly, can on very little area, stop, second problem is the folding traditional lateral direction of car foldover design pattern that changed that arches upward, can be used for the portable electric car, the traditional electrical motor-car generally is can not be portable.

The 1-tressel, the 2-foldable structure, the 3-expansion link, the 4-front-wheel, the 5-trailing wheel, the 6-front vehicle frame, vehicle frame behind the 7-, 8 additional middle wheels, the 9-cardan wheel, 10-class hinge wing extends, 11-quick detach joint.

The specific embodiment:

Below in conjunction with accompanying drawing, the present invention will be described in more detail, a kind of folded bicycle, comprise front vehicle frame 6, back vehicle frame 7, the front-wheel 4 of front vehicle frame front portion, the trailing wheel 5 at back vehicle frame rear portion, electric driver, front vehicle frame 6 and back have the one two wing class hinge foldable structure 2 that can arch upward folding that sways between the vehicle frame 7, and its improvement is: also have the unsettled underwork of folding and expanding.Owing to increased the unsettled underwork of folding and expanding, folding like this node contacts with ground with regard to not falling because of deadweight or load in the process of moving, such improvement has increased the admissible length of vehicle front and back vehicle frames greatly, the deadweight of vehicle frame before and after reducing, improved the expansion and contraction between two states, if be 1 meter length gauge with the front and back Vehicle Frame Design, 0.3 meter meter of wheel diameter design, the length of run of then travelling reaches about 2 meters, and contraction state takes up an area of length near promptly 0.45 meter of one and half wheel diameter, expansion and contraction reaches more than 75%, also satisfies large span simultaneously, low center of gravity, the requirement of top load.

Can also do such improvement: described unsettled underwork is such, front vehicle frame 6 is that class hinge wing oppositely extends 10, as shown in Figure 5, be equivalent to a hinge with screens structure control corner size, just can reach the folding unsettled purpose of node by hinge screens itself like this, it is the unsettled support pattern of the simplest folding node that this monolateral or bilateral hinge wing extends screens, has the advantage that vital part is few, cost is low.

Can also do such improvement: described unsettled underwork is the additional wheel 8 at closely folding node place.As shown in Figure 3, because middle wheel 8 lands, the foldable structure place itself does not stress, and such structure makes folding position of joints have maximum load-carrying capacity, because opinion 8 loads of bearing on it in can leaning on fully.

Can also do such improvement: described unsettled underwork is the expansion link 3 that connects between front vehicle frame 6 front portions and vehicle frame 7 rear portions, back, forms the triangle rock-steady structuries with class hinge foldable structure 2, as shown in Figure 1, has the flexible cooperation of best load and vehicle.This also is a best mode for carrying out the invention.

Can also do such improvement: wheel is the cardan wheel 9 of bottom of frame in described, as shown in Figure 4, has increased the stability of vehicle running state and the alerting ability when turning to.

Can also do such improvement: have Shock absorber on the described expansion link 3, to reduce the impulsive force of vehicle triangle carrying structure, increase the passenger comfort level simultaneously, this Shock absorber generally is made up of spring.

Can also do such improvement: described expansion link 3 is hydraulic cylinder structure or screw rod/nut structure, reach flexible purpose by air pressure or hydraulic pressure, perhaps nut/screw rod rotation cooperation reaches flexible purpose, and such stretches and also easily realizes automation simultaneously.

Can also do such improvement: described expansion link 3 is chain or rope, has maximum extendable room, reduces cost simultaneously.

Can also do such improvement: still have tressel 1, one end to sway with the car body termination on the described vehicle frame and be connected, another termination quick release of an end and car body is connected.The general selection of tressel itself is arc, the tressel bow-shaped structural cooperates with folding car body, form the shape elastic body that draws a bow, can increase the elastic stiffness and the safety of whole vehicle structure effectively, this fast quick-detach connection mode can find in some current techiques, such as plug-in type, embedded, be threaded etc., the quick detach joint 11 of tressel 1 other end can be straight-bar, cross bar, bulb and other shapes accordingly.

Can also do such improvement: described electric driver is wheeled driving, at least one of them wheel is a drive wheel, be the charged actuating device of wheel itself, this electric type of drive can reduce the assembling complexity of battery-driven car substantially, thereby improves the reliability and maintainability of vehicle operating.

In a word; the present invention is not limited to above-mentioned preferred forms; anyone can make other forms of product under enlightenment of the present invention, no matter but its structure or shape have anything to change, and any and similar techniques scheme of the present invention all falls into protection scope of the present invention.
