The specific embodiment

As shown in Figures 1 to 4, light electric vehicle of the present utility model takes advantage of a portion 3, one transmission devices 4 and a secondary pressure mechanism 5 to be combined by a car body 1, one actuation means 2.

Wherein, car body 1 is to strengthen design-calculated vehicle frame 11 once stress structure, the outside then according to its appearance with a case 12 with it coating, form curtain-shaped cover member and take advantage of a function that bridges.These vehicle frame 11 1 side shafts connect an actuation means 2, and with the control as direction, side is then prominent in addition establishes a frame-saw portion 13, takes advantage of a portion 3 so that the top connects one, the ccontaining and location of transmission device 4 that the below is chatted after then supplying and secondary pressure mechanism 5.And being different from the known technology part, the utility model is that vehicle frame 11 rear two side ends articulate a flower wheel 14 separately.

Actuation means 2 is with an axostylus axostyle 21 belows front vehicle wheel 22 that is coupling, and the top then connects a handle 23, by rotating handle 23, can make the front vehicle wheel 22 of its bottom turn to, with the control direct of travel.See also Fig. 7 and Fig. 8, these axostylus axostyle 21 belows are provided with a button spigot 24, by to the pine of a Button Handle 241/tight control, can make that axostylus axostyle 21 is a fulcrum with button spigot 24, and topple over downwards, or axostylus axostyle 21 is erect, as the foundation of taking in or travelling.In addition, this handle 23 also can be coupling in axostylus axostyle 21 tops by a button spigot 24, to the control of its Button Handle 241, can allow handle 23 in suitable angle rotation and location (as shown in Figure 8), with the different builds in response to the rider, considers and have hommization.Please consult Fig. 7 again, these frame-saw portion 13 end faces are provided with a fastener 15, turn over and be cross-placed on the pedal of case 12 for 3 times when the portion of driving after, with axostylus axostyle 21 times folding, make fastener 15 be buckled in handle 23 again, promptly finish and take in step, and can significantly dwindle the packing volume of timber.

As Fig. 2 and shown in Figure 6, take advantage of a portion 3 to be located at frame-saw portion 13 tops, above a cradle portion 31, connect a seat 32, the seat of taking advantage of for the rider, as previously mentioned, for make take advantage of a portion 3 below turn over, be with these cradle portion 31 1 sides two L shaped before bar 311 lower shaft be connected to frame-saw portion 13 1 sides, bar 312 tops, two of side backs then are coupling in preceding bar 311 ora terminalis in addition, the below then is intercalated in 13 corresponding bar holes 16 that are provided with of frame-saw portion, the stationary state that seat 32 is formed as Fig. 1 and Fig. 2, the perhaps following receiving state that turns over as shown in Figure 7.

Transmission device 4 is fixedly arranged between frame-saw portion 13 belows and two flower wheels 14 of vehicle frame 11, it is by moving 41 and one output unit 42 of an electronic horse, for example members such as turbine, belt, chain or gear are formed, and the output shaft 421 of its extension and a driving wheel 43 are articulated, when motor 41 is obtained power supply by a storage battery 44 and is started, by the rotation of the output shaft 421 of output unit 42, can make this driving wheel 43 bear and start the function of travelling and stopping to brake.Because driving wheel 43 of the present utility model is arranged between two flower wheels 14, make the flower wheel 14 of its both sides at any time can be in response to various situations, and do constant speed or non-constant speed drive, so need not to install additional any box of tricks, can make battery-driven car of the present utility model when turning, the embarrassed shape that the unlikely danger of toppling over maybe can't be turned.

Secondary pressure mechanism 5 mainly provides the utility model in motion, and the flower wheel 14 of both sides is propped up driving wheel 43 and unsettled in uneven or the road surface of jolting, and it contact with ground, and lose the function of travelling and braking.Be above a support 51, to connect a core bar 53 that is with a stage clip 52, and core bar 53 tops make support 51 and groove frame 54 common clamping stage clips 52 by a groove frame 54 that is fixedly arranged on frame-saw portion 13 with, this secondary pressure mechanism 5.Support 51 belows then link with output unit 42, and clamping one torsion spring 55, and the one movable end are overlapped in output unit 42 therebetween.In addition, this output unit 42 bridges and is fixed on the U-shaped suspension plate 56, and these suspension plate 56 medial extremitys then are connected in the fixed mount 17 at vehicle frame 11 rears, makes the whole transmission device 4 can be according to ground state along with the 5 longitudinal elasticity displacements of secondary pressure mechanism.

Wherein, the purpose that this torsion spring 55 is provided with is that when not driving, the pressure of this torsion spring 55 can absorb the car weight of empty wagons, it is unlikelyly propped up flower wheel 14, and then cause tilting of car body, and guarantee in injustice or bumpy sections the brake function is also arranged.And the purpose that stage clip 52 is provided with is, when driving, because of being subjected to bigger weight, and travel when injustice or bumpy sections, allow driving wheel 43 lifting arbitrarily, keep forever contact, and then bring into play the function that startup is travelled and stopped to brake with ground, and its various emulation modes see also Fig. 5 A to Fig. 5 F.

Via enforcement of the present utility model, transmission device and driving wheel are located between two flower wheels, and suspention is installed in the secondary pressure mechanism, by this secondary pressure mechanism, driving wheel is contacted constantly with ground, unlikelyly cause the puzzlement that can't travel or brake.In addition, travel and brake by the driving wheel between two flower wheels for it owing to of the present utility model, therefore, when turning, need not any box of tricks, this two flower wheel gets final product constant speed or non-constant speed drive, not only can obtain differential effect simply again.And actuation means of the present utility model and take advantage of a portion all can turn over down is with as taking in or instant packed.

The utility model disclosed preferred embodiment a kind of just, such as Ju Bu change or modification and come from technological thought of the present utility model and be have the knack of this technology the people was easy to know by inference, all do not take off patent category of the present utility model.
