The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in the figure, this type folding electric vehicle mainly comprises a casing 1, casing is divided into three zones by ⊥ type internal partition: upper right quarter 11, upper left quarter 12 and bottom 13, wherein upper right quarter 11 is used for placing the flexible barre 7 of cushion 18, step 3 and band telescoping handle 71, upper left quarter 12 is used for placing the storage battery (not shown), and bottom 13 is connected with center shock absorbing apparatus 8, trailing wheel shock absorbing apparatus 9 and be used for collecting battery-driven car each parts such as trailing wheel 5, front-wheel 4 and pedal 2 after folding.The top of casing 1 is shaped on several can supply cushion bonded assembly jack 15, after casing is assembled into battery-driven car, just this cushion 18 can be taken out, and is contained in the casing top, and a seat can be provided.Lock 17 also is housed, so that open or close casing on casing 1.Therefore when not using, the equal folding storage of each member of battery-driven car is only seen the simple casing for as shown in Figure 3 from the outside in casing.

The pivot hole that can articulate for pedal is arranged on the front side wall of casing 1, and the middle part has one can be for the opening 16 that center shock absorbing apparatus 8 is set, and the pedal 2 of battery-driven car articulates with the casing front side wall, and fixes with latch is spacing.And the rotation step 3 of band stepless speed-regulating device is fixed on the appropriate position of pedal 2 front portions, but these two steps, 3 equal demolitions can be concealed in the upper right quarter 11 of casing, the brake gear of this battery-driven car is controlled by step 3.Before articulating, the front end of pedal 2 props up 6, and spacing fixing with movable latch.Flexible barre 7 connects by nut with preceding 6, has collapsible telescoping handle 71 on the barre.Front-wheel 4 is connected with preceding fixing front-fork 41 with one.

The structure of center shock absorbing apparatus as shown in Figure 5, it by a sleeve pipe 81, a slide bar 82, and two

springs

83,84 constitute, sleeve pipe 81 is rotationally connected through casing front side wall opening 16 and cabinet wall, slide bar 82 1 ends are rotatably connected on the appropriate position of pedal 2, the other end inserts in the sleeve pipe 81, sleeve pipe slides relatively, and

spring

83,84 is located in the sleeve pipe, is supported on respectively between sleeve pipe roof and the slide bar top exterior walls to reach between slide bar top inner wall and the sleeve pipe diapire.When battery-driven car travels, run into rugged road surface, this device can play good buffer action.

The bottom of casing internal partition is fixed with a support 19, and there is the pivot hole its both sides, rear wheel fork 51 and its pivot joint, and the available active latch is spacing fixing, trailing wheel 5 is fixing with rear wheel fork 51.Trailing wheel 5 adopts the motor integral wheel hub, and it is similar to traditional battery-driven car with being connected of driving device, storage battery, is not described in detail in this.

Trailing wheel shock absorbing apparatus 9 is installed in 5 of casing 1 and trailing wheels, and it can play good buffer action to trailing wheel.Its structure as shown in Figure 6, it mainly is made of an outer tube 91, inner sleeve 92, T type slide bar 93 and two

springs

94,95, one end and the casing internal partition 14 of outer tube 91 are rotationally connected, one end of inner sleeve 92 places in the outer tube 91 and slidably, establishes spring 94 between inner sleeve 92 and outer tube 91 inwalls.One end of T type slide bar 93 places in the inner sleeve 92 and slidably and rotate, establishes a spring 95 between slide bar 92 and inner sleeve 92 diapires.And between the outer wall of outer tube and box partition, one extension spring 97 being housed, a draw ring 96 is equipped with in the slide bar bottom.

When battery-driven car folds into casing, to unload step 3, flexible barre 7 earlier, and they are collected in the upper right quarter 11 of casing.Take off the movable latch of each junction then, trailing wheel 5 is rotated the right side that is installed in lower box, pedal 2 rotations are installed in lower box, and front-wheel 4 rotations are installed in the left side, fold like this and finish, each member of battery-driven car all is concealed in the casing and constitutes a box-structure.

When casing is assembled into battery-driven car, should at first casing 1 be opened turn in sequence front-wheel 4 and trailing wheel 5, trailing wheel 5 usefulness trailing wheel shock absorbing apparatus 9 are fixing, front-wheel 4 and pedal 2 usefulness nuts are fixed, taken out barre 7, step 3, cushion 18 then and load onto, just constitute the main body of battery-driven car.
