Detailed description of the invention
Please first consult Fig. 1 and Fig. 2, electronic transmission 10 of the present utility model includes vehicle frame permanent seat 20, linkage unit 30, chain guides 40, and a driver element 50.
Vehicle frame permanent seat 20 is arranged on a vehicle frame 12 of bicycle by a bolt of rear end plate 22, in order to as main support structure.
Linkage unit 30 has continous action base 31 and an outer continous action base 32 in one.The top of interior continous action base 31 is articulated in vehicle frame permanent seat 20 by one first pivot P1, and the bottom of interior continous action base 31 is articulated in chain guides 40 by one second pivot P2, and in addition, the middle position of interior continous action base 31 has a circular tank 33; The top of outer continous action base 32 is articulated in vehicle frame permanent seat 20 by two relative the 3rd pivot P3, and the bottom of outer continous action base 32 is articulated in chain guides 40 by one the 4th pivot P4, and in addition, the top of outer continous action base 32 has an arc notch 34.On the other hand, linkage unit 30 also has a torque spring 35, and torque spring 35 is sheathed on the second pivot P2 and is connected to interior continous action base 31 and chain guides 40 respectively, in order to provide reset strength with its two ends.
As shown in Figures 2 and 3, driver element 50 has a motor 51, motor 51 has shell 52 and a rotating shaft 53, interior continous action base 31 is articulated in by two relative Wushu axle P5 in the circular tank 33 that shell 52 is arranged in interior continous action base 31, one end of rotating shaft 53 is arranged in shell 52, and it is outer and have a spiral shell block 54 that one end of rotating shaft 53 is positioned at shell 52.In addition, driver element 50 has more a moving member 55, the top of vehicle frame permanent seat 20 and outer continous action base 32 is articulated in by the 3rd pivot P3 in the arc notch 34 that moving member 55 is contained in outer continous action base 32, in addition, moving member 55 has an axial screw 56, the aperture of axial screw 56 is greater than the external diameter of the shell 52 of motor 51, moving member 55 is bolted in by axial screw 56 outside the spiral shell block 54 of the rotating shaft 53 of motor 51, is sheathed on the first half of the shell 52 of motor 51 simultaneously by axial screw 56.
From said structure, when the rotating shaft 53 of motor 51 starts to rotate, as shown in Figures 3 and 4, motor 51 can by axially the moving axially of screw 56 of the relation that is spirally connected between spiral shell block 54 and the axial screw 56 of moving member 55, in the process of motor 51 movement, as the 2nd, shown in 5 and 6 figure, the shell 52 of motor 51 can drive interior continous action base 31 relative frame permanent seat 20 to deflect, when interior continous action base 31 starts to deflect, moving member 55 relative frame permanent seat 20 can be forced to deflect through driving the shell 52 of motor 51 on the one hand, chain guides 40 can be driven again to shift one's position on the other hand, can outer continous action base 32 relative frame permanent seat 20 be driven again to deflect in the process that chain guides 50 are shifted one's position, so speed changing effect can be reached.
In sum, motor 51 is configured in the mode of upside-down mounting by electronic transmission 10 of the present utility model, and the some of motor 51 is built in moving member 55, making motor 51 can be positioned at continous action base 31 after mounting can not be outwardly near the side of trailing wheel, the risk that motor 51 clashed into by foreign matter can be reduced like this and the speed change precision avoiding motor 51 is affected, motor 51 can be prevented to be subject to when bicycle falls down clashing into damage simultaneously, also can shorten the entire length of driver element 50 in addition, and then reach the purpose of this utility model.
