Embodiment
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
For a pedal power generating device for electric motor car emergent charging, comprise base plate 1, pedal linkage mechanism that the crankshaft & connecting be installed on base plate 1, generator 2, two structures are identical and for the fore poppet 4 of fixed pedestal linking mechanism and back poppet 3; Described crankshaft & connecting is in transmission connection by gear and generator 2; Connecting rod 7, two connecting rods 7 that described crankshaft & connecting is provided with two carrier phase shift 90 degree are connected with pedal linkage mechanism by spherical linkage.
The connecting rod 7 that described crankshaft & connecting comprises a bent axle 6, supporting frame 5, two is provided with spherical linkage and be installed on first driving gear 8 of output terminal of bent axle 6; The two ends of described bent axle 6 are fixedly connected with base plate 1 by supporting frame 5; Described generator 2 is provided with the second driving gear 9 engaged with the first driving gear 8.
Ride the generated energy of action to improve the utility model single, the number of teeth of described first driving gear 8 is greater than the number of teeth of described second driving gear 9, and selects suitable velocity ratio to improve the working efficiency of whole device according to the model of selected generator 2.
Described pedal linkage mechanism comprises the pedal 10 hinged with back poppet 3, be installed on the push rod 11 of pedal 10 front lower portion, be installed on pedal 10 front lower portion and the spring 12 be connected with fore poppet 4, the slide block 14 that is installed on the linear rail 13 on base plate 1 and is installed on linear rail 13.
Described slide block 14 is trigonal slider, slide block 14 by spherical linkage and described connecting rod 7 hinged.
Wherein, slide block 14 adopts triangular design, mainly described push rod 11 is become the horizontal motion of described slide block 14 linearly guide rail 13 along the conversion of motion of the Vertical direction of pilot hole, with driving crank 6 connecting rod 7 mechanism action and then drive described generator 2 to generate electricity.
Described slide block 14 is provided with the guide surface of inclination, guide surface offers guiding groove 14a.
The upper end rotary type of described push rod 11 is connected to the bottom of pedal 10; The lower end of push rod 11 connects through the pilot hole on fore poppet 4 and described slide block 14.
The lower end of described push rod 11 is provided with slide guide wheel 11a; Width 2 ~ the 3mm less of the width of described guiding groove 14a of described slide guide wheel 11a, and the periphery of slide guide wheel 11a contacts with the bottom surface of guiding groove 14a, the little 5 ~ 10mm of radius of the depth ratio slide guide wheel 11a of guiding groove 14a.
It should be noted that, in order to reduce the energy loss of the internal system of whole device, various friction should be reduced as far as possible, therefore slide guide wheel 11a is provided with bottom described push rod 11, coordinate the guiding groove 14a on described slide block 14, push rod 11 is pushed up the rolling friction of pressing the sliding friction of described slide block 14 to change the bottom land of slide guide wheel 11a top pressure guiding groove 14a into; The width of the slide guide wheel 11a is simultaneously less than the width of described guiding groove 14a, takes turns the non-slide guide face of 11a and the sidewall contact of guiding groove 14a to avoid slide guide; And the degree of depth that the diameter of described slide guide wheel 11a is greater than described guiding groove 14a mainly produces extra surface friction drag to prevent the part on push rod 11 except slide guide takes turns 11a and the guide face contacts on described slide block 14, reduce the energy loss of internal system to greatest extent.
In addition, the effect of described spring 12 is in double-legged trample action process, the pedal 10 be in non-working stroke automatically returns to top dead center and provides active force upwards; The active force vertically upward that spring 12 improves ensures that the push rod 11 in return stroke can not apply pressure to the slide block 14 in return stroke, reduces intrasystem resistance to greatest extent, improves the working efficiency of this electricity generating device.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
