Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The middle-mounted generator set (hereinafter referred to as the middle-mounted generator set) for the scooter shown in the attached figure 1 is used for recovering mechanical energy in the running process of the scooter and comprises a base 1, wherein a stator 2 is fixedly arranged on the base 1, and a rotor shaft 3 and a main shaft 4 which are arranged in parallel are rotatably arranged on the base 1.
The stator 2 is fixedly arranged on an end cover included in the base 1, and the stator 2 can be disassembled and assembled by disassembling and assembling the end cover; both ends of the main shaft 4 are used for connecting cranks with pedals, when a user rides the scooter provided with the built-in generator set, the main shaft 4 can be driven to rotate by pedaling the pedals, and the main shaft 4 can transmit power to a driving wheel of the scooter so as to drive the scooter to run; the rotor shaft 3 is provided with a rotor 5, and the rotor 5 can be matched with the stator 2 to generate electric energy when rotating under the action of external force; a transmission relation is established between the main shaft 4 and the rotor 5 through the speed increasing mechanism, so that when a user steps on the main shaft 4 to rotate, the main shaft 4 transmits torque to a driving wheel of the scooter on one hand, and on the other hand, the rotor 5 is driven to rotate through the speed increasing mechanism, and a power generation assembly formed by the rotor 5 and the stator 2 generates electric energy. The speed increasing mechanism comprises a primary gear speed increasing mechanism and a planetary gear speed increasing mechanism; and a one-way driving element 6 is arranged between the main shaft 4 and an input part of the speed increasing mechanism.
By adopting the structure, the speed increasing mechanism comprising the planetary gear speed increasing mechanism is arranged, the integral speed ratio of the speed increasing mechanism can be greatly improved, so that when the main shaft 4 rotates at the same speed, the rotor 5 can obtain higher rotating speed, and more electric energy is generated.
Specifically, the primary gear speed increasing mechanism comprises a first gear 7 and a second gear 8, wherein the first gear 7 is coaxially arranged with the main shaft 4, the second gear 8 is coaxially arranged with the rotor shaft 3, the first gear 7 is meshed with the second gear 8, and the number of teeth of the first gear 7 is larger than that of the second gear 8; the first gear 7 is an input component of the speed increasing mechanism, and in fact, after the mid-set generator set is applied to the scooter, the first gear 7 also has a function of outputting torque to a driving wheel of the scooter, and output components such as gears, chain wheels and the like can be arranged on the first gear 7 so that the first gear 7 can output torque.
The planetary gear speed increasing mechanism comprises a planet carrier 9, a planet gear 10, an inner gear ring 11 and a sun gear 12; the planet carrier 9 is rotatably mounted relative to the base 1, the inner gear ring 11 is fixed relative to the base 1, the sun gear 12 is fixed to the rotor shaft 3, the second gear 8 and the planet carrier 9 are relatively fixed (the second gear 8 and the planet carrier 9 can be made into an integral part to reduce the processing and assembling difficulty), the planet gear 10 is rotatably mounted on the planet carrier 9, and the planet gear 10 is simultaneously meshed with the inner gear ring 11 and the sun gear 12. The second gear 8 is connected with an input component of the planetary gear speed increasing mechanism as an output component of the primary gear speed increasing mechanism, so that the rotating speed increased by the primary gear speed increasing mechanism is further increased by the planetary gear speed increasing mechanism, and the sun gear 12 is used as an output component to finally output the rotating speed increased by the whole speed increasing mechanism to the rotor shaft 3.
When the setting of one-way drive element 6 made only main shaft 4 forward rotation, first gear 7 just can follow forward rotation, and main shaft 4 antiport can not drive first gear 7 antiport, and when the rotational speed of first gear 7 was higher than main shaft 4 rotational speed, first gear 7 can not reverse drive main shaft 4 and accelerate. So, when actually will put generating set and be applied to the car of riding instead of walk, have two kinds of mechanical energy recovery situations, respectively as follows:
the first case: when a user steps on a pedal to drive the scooter to move forward, one part of kinetic energy output to the main shaft 4 by the user is transmitted to the driving wheel through the output part connected with the first gear 7 so that the scooter runs, the other part of kinetic energy is transmitted to the rotor 5 through the speed increasing mechanism, and the rotor 5 and the stator 2 are converted into electric energy through the matching action.
The second case: under the sliding conditions of the scooter such as downhill and the like, the scooter has high kinetic energy, the driving wheel drives the first gear 7 to rotate reversely, the first gear 7 transmits power to the rotor 5 through the speed increasing mechanism, and the rotor 5 and the stator 2 are converted into electric energy under the matching action. In this case, the main shaft 4 does not rotate with the first gear 7 due to the presence of the unidirectional drive element 6.
In this embodiment, planet carrier 9 rotates to be installed on rotor shaft 3, and is provided with fifth bearing 17 between the two, so, planet carrier 9 installs indirectly for pedestal 1 rotation installation on rotor shaft 3 through rotating, can guarantee planet carrier 9 and sun gear 12's axiality, reduces the assembly degree of difficulty.
The planetary gear speed increasing mechanism with a large size is adopted in the middle-placed generator set, so that the overall size of the middle-placed generator set is not increased, the compactness of the structure of the middle-placed generator set is improved, the rotor 5 is an outer rotor and is provided with the accommodating cavity, the stator 2 is arranged in the accommodating cavity, and the structure of the inner stator of the outer rotor is adopted, so that the size of a main body part of a generator formed by the rotor 5 and the stator 2 is obviously reduced under the condition of the same power, the space occupied by the planetary gear speed increasing mechanism is made up, the overall structure of the generator set is compact, and the size cannot be.
Preferably, in order to further improve the compactness of the structure, the center of the stator 2 is provided with a center hole, a first bearing 13 is installed in the center hole, and a second bearing 14 is installed on the machine base 1; the first bearing 13 and the second bearing 14 support the rotor shaft 3. Adopt above-mentioned structure, because stator 2 installs on the end cover that pedestal 1 contains, through placing first bearing 13 in the centre bore in, stator 2 has still played the effect of bearing frame, and first bearing 13's use can not occupy extra axial space, has guaranteed the compactedness of structure.
