Description
[technical field]
The utility model relates to a kind of electric bicycle, is meant especially more than a kind of three-wheel, and is the electric bicycle in major impetus source with electric power.
[background technology]
Along with the affluence of goods and materials, the general mood day of people amusement and travel contains, wherein again based on the tool development potentiality of the stress-relieving activity of three-wheel electric bicycle.Because the three-wheel electric bicycle is the light-duty short distance range of driving, and originates as major impetus with electric power, have facility, comfortable, pollution-free noise simultaneously concurrently, and be difficult for advantage such as fault, therefore be fit to very much develop into stress-relieving activity.In addition, three-wheel vehicle is Chinese intrinsic characteristic, therefore also has the value that develops into the sightseeing industry.
Existing on the market at present three-wheeled electric vehicle is of a great variety, yet, all do not have the foot-driven function.Cause when three-wheeled electric vehicle loses the power source of driving, then can't drive again, therefore, its essentiality is arranged really in conjunction with the type of drive of electric power and manpower.But, directly make existing two design architectures of taking turns electric bicycle develop into the non-best solution of three-wheel electric bicycle.
Consult Fig. 1, existing two take turns electric bicycle 1 comprises a vehicle frame 11, and is located at the electric device 13 that the set of wheels 12, of this vehicle frame 11 is located at this set of wheels 12, and a pedal driver 14.
This set of wheels 12 comprises a front-wheel 121 and a trailing wheel 122.This electric device 13 is located at the bearing of this trailing wheel 122, and in order to drive this trailing wheel 122.This pedal driver 14 is located at this vehicle frame 11, and comprises that a pedal unit 141, connects the chain drum 142 of this pedal unit 141, and one with these chain drum 142 engagement and chains 143 in order to drive this trailing wheel 122.
This electric device 13 is the hub motor of relevant title that the dealer practises at present, though this electric device 13 is to be arranged at this trailing wheel 122 shown on figure, in fact this electric device 13 also can be arranged on this front-wheel 121, and the two has identical effect purpose.
When same architecture design is applied mechanically to the three-wheel electric bicycle, but can't reach identical effect purpose.Because a three-wheel electric bicycle has a front vehicle wheel and two corresponding rear wheels, thus when be provided with an electric device 13 in these rear wheels one of them the time, certainly will be when driving the uneven problem of the generation application of force.But if two electric devices 13 are set when these rear wheels simultaneously, then cost is too high and uneconomical.
On the contrary, if an electric device 13 is set when this front vehicle wheel, though can solve the above problems, yet this moment, the forward and backward counterweight of this three-wheel electric bicycle then seemed uneven, not only be unfavorable for controlling, even when going up a slope, the front vehicle wheel that is driven causes this three-wheel electric bicycle to advance easily because of the earth-grasping force deficiency.
[utility model content]
The purpose of this utility model is promptly providing a kind of electric bicycle, has electric power and manpower simultaneously and drives, and can realize that the balanced application of force drives and make the counterweight equilibrium.
A kind of electric bicycle of the present utility model is characterized in that: include:
One vehicle frame comprises a leading portion portion and a back segment portion;
A wheel apparatus and a back wheel apparatus before one are hubbed at described front and rear sections portion respectively, and described back wheel apparatus comprises the rear wheel of two configured in parallel, and a wheel shaft between described rear wheel;
One actuating device comprises and is located at the pedal unit that described back segment portion and the electrodynamic element between described rear wheel and are located at this vehicle frame; And
One bearing arrangement is located at described back segment portion and is comprised that one connects the unidirectional gear unit of described electrodynamic element and described pedal unit simultaneously, makes the transmission of power of described electrodynamic element and described pedal unit to this wheel shaft with uniaxially respectively.

[specific embodiment]
For convenience of description, following embodiment, components identical is represented with same numeral.
As shown in Figure 2, the preferred embodiment of the utility model electric bicycle comprises a vehicle frame 3, one preceding wheel apparatus 4, a back wheel apparatus 5, a bearing arrangement 6, an actuating device 7, and a brake gear 8.。
This vehicle frame 3 comprises an oppositely directed leading portion portion 31 and a back segment portion 32.
Shown in Fig. 3,4, wheel apparatus 4 and this back wheel apparatus 5 are hubbed at this front and rear sections portion 31,32 respectively before being somebody's turn to do, and this back wheel apparatus 5 comprises the rear wheel 51 of two configured in parallel, and one between these rear wheels 51 and the wheel shaft 52 in order to drive these rear wheels 51.
This bearing arrangement 6 is located at this back segment portion 32 and is comprised that the unidirectional gear unit 61, of a ring-type connects this unidirectional gear unit 61 and this wheel shaft 52, driving first gear unit 62 of these wheel shafts 52 by this unidirectional gear unit 61, and a diff 63 between this first gear unit 62 and this wheel shaft 52.
This diff 63 is in order to freely distributing these rear wheel 51 rotating speeds, the inequality of these rear wheels 51 of balance on rotating speed when turning to.The thin portion member and the action specification of relevant this diff 63 can just repeat no more at this with reference to No. 206488 patent case of Taiwan patent announcement.
This first gear unit 62 comprises that one connects first chain drum 621 of this unidirectional gear unit 61, reaches one with these first chain drum, 621 engagements and in order to drive first chain 622 of this wheel shaft 52.
