Therefore, when the vehicle accelerates or decelerates, the pendulum 24 of the power pendulum 2 swings around the first pivot shaft 1 to drive the sector 22 to move, the teeth 23 of the sector 22 drive the first gear 41 of the amplifying gear set 4 to rotate, the first gear 41 drives the second gear 42 to rotate, the second gear 42 drives the power gear 6 to rotate, and meanwhile, the power gear 6 applies external force to the first external teeth 91 of the first flywheel 9 through the first transmission member 7 and applies external force to the second external teeth 101 of the second flywheel 10 through the second transmission member 8 during rotation, so that the first internal core (not shown in the figure) of the first flywheel 9 and the second internal core 102 of the second flywheel 10 can rotate. The first inner core and the second inner core rotate in the same direction, and when the first inner core and the second inner core rotate, the rotor 1101 of the motor 110 is driven to rotate, so that the motor 110 generates electric energy.
In the following, the embodiments of the present invention are exemplified by the generation of electric energy when the vehicle is accelerated and decelerated, respectively.
It should be noted that, according to the characteristics of the flywheel, the inner core of the flywheel can rotate clockwise or counterclockwise when the outer teeth are subjected to a clockwise external force. In this embodiment, the first flywheel 9 and the second flywheel 10 are reverse flywheels, and the first inner core and the second inner core 102 are arranged in the same rotation direction. Hereinafter, the embodiment of the present invention will be described by taking an example in which the first inner core rotates clockwise when the first external teeth 91 of the first flywheel 9 receive a clockwise external force, and the second inner core 102 rotates clockwise when the second external teeth 101 of the second flywheel 10 receive a counterclockwise external force.
In one application example, the vehicle is explained as starting acceleration and then decelerating. When the automobile starts to accelerate first, the pendulum 24 swings backward, which drives the sector 22 to swing forward, and the first gear 41 and the second gear 42 of the acceleration gear set 4 both rotate clockwise (the clockwise direction or the counterclockwise direction in this document refers to the rotation direction viewed from the perspective of the power pendulum 2 looking at the motor 110), and drive the power gear 6 to rotate clockwise, and meanwhile, the power gear 6 rotating clockwise applies a clockwise external force to the first external teeth 91 of the first flywheel 9 through the first transmission member 7, and also applies a clockwise external force to the second external teeth 101 of the second flywheel 10 through the second transmission member 8. According to the characteristics of the flywheels, the first inner core of the first flywheel 9 starts to rotate clockwise, and at this time, the second inner core 102 of the second flywheel 10 does not rotate due to the external force, but because the second inner core 102 and the first inner core are both fixedly connected with the third pivot shaft 5, the second inner core 102 starts to rotate under the driving of the first inner core. The clockwise rotation of the first inner core of the first flywheel 9 can drive the rotor 1101 to rotate clockwise, thereby generating electric energy. When the automobile decelerates in the process of running after acceleration, the pendulum bob 24 swings forwards to drive the sector part 22 to swing backwards, the gears of the acceleration gear set 4 rotate anticlockwise and drive the power gear 6 to rotate anticlockwise, meanwhile, the power gear 6 rotating counterclockwise applies a counterclockwise external force to the first external teeth 91 of the first flywheel 9 through the first transmission member 7, a counterclockwise external force is applied to the second external teeth 101 of the second flywheel 10 through the second transmission piece 8, according to the characteristics of the flywheels, the first inner core of the first flywheel 9 still keeps rotating clockwise after the first outer teeth are subjected to the anticlockwise external force, and the second inner core 102 of the second flywheel 10 rotates clockwise when the second outer teeth 101 receive an external counterclockwise force, and the first inner core and the second inner core 102 rotate clockwise simultaneously and drive the rotor 1101 to rotate continuously, so that electric energy can still be generated when the speed is reduced after acceleration.
In another example of application, when the vehicle first starts to decelerate and then accelerates, the principle of operation is substantially the same as that of the above example of application, but in the opposite direction. This is only briefly described here. When the automobile is decelerated, the power gear 6 rotates counterclockwise to apply counterclockwise external force to the first outer teeth 91 and the second outer teeth 101, respectively, according to the characteristics of the flywheel, the second inner core 102 of the second flywheel 10 rotates clockwise, and drives the first inner core of the first flywheel 9 and the rotor 1101 to rotate clockwise, so that electric energy is generated. When the automobile accelerates in the driving process after deceleration, the power gear 6 rotates clockwise to apply clockwise external force to the first outer teeth 91 and the second outer teeth 101 respectively, according to the characteristics of the flywheels, the second inner core 102 of the second flywheel 10 still keeps rotating clockwise, and the first inner core of the first flywheel 9 rotates clockwise when the first outer teeth 101 receive the clockwise external force, therefore, the first inner core and the second inner core 102 simultaneously rotate clockwise and drive the rotor 1101 to rotate continuously, so that electric energy can still be generated when the automobile accelerates again after deceleration.
By arranging the first flywheel and the second flywheel, external force can be applied to the flywheels no matter the automobile is accelerated or decelerated, so that inner cores of the two flywheels can keep rotating in the same direction, the rotating speed of the rotor 1101 is kept, and the motor 110 can continuously generate electric energy.
The distance between the pendulum 24 and the first through hole 25 is smaller than the distance between the sector 22 and the first through hole 25, and conforms to a first preset proportion, the first preset proportion can be set according to actual needs, and the distance between the sector 22 and the first through hole 25 is larger than the distance between the pendulum 24 and the first through hole 25 as far as possible under the condition of meeting the size requirement, so that the stroke of the sector 23 can be increased, the external force applied to the flywheel can be increased by the power gear 6, the rotating speed of the inner core of the flywheel is increased, and the motor 110 can generate more electric energy under the condition of the same acceleration.
In addition, in order to increase the stroke of the pendulum 24, as an optional implementation manner of the embodiment of the present invention, the pendulum 24 includes an extending member 26, the extending member 26 is disposed perpendicular to the link 21, the end of the extending member 26 has a fixing portion 27 parallel to the link 21, a second through hole 28 is disposed on the fixing portion 27, the first pivot shaft 1 is pivotally connected to the pendulum 24 through the second through hole 28, and the second through hole 28 and the first through hole 25 are disposed correspondingly in the extending direction of the first pivot shaft 1. Therefore, the size of the pendulum bob 24 is structurally increased, the weight of the pendulum bob is increased, the stroke of the pendulum bob 24 can be increased in the acceleration and deceleration movement of the automobile, and meanwhile, the electric energy generating device of the vehicle-mounted unit is convenient to mount during subsequent mounting.
As an optional implementation manner of the embodiment of the present invention, the extension part 26 and the flywheel, the motor and other parts are disposed on the same side of the power pendulum 2, so that the extension part 26 can reasonably utilize the lower space of the flywheel, the motor and other parts, and the volume of the electric energy generating device of the on-board unit can be reduced.
In order to increase the stroke of the multiplier gear set 4, as an alternative to the embodiment of the invention, the first gear 41 has a pitch circle diameter smaller than the pitch circle diameter of the second gear 42 and corresponding to a second predetermined ratio. The second preset proportion can be set according to actual requirements, and under the condition of meeting the size requirement, the reference circle diameter of the second gear 42 is made to be larger than that of the first gear 41 as much as possible, so that the stroke of the amplifying gear set 4 can be increased, the external force applied to the flywheel can be further increased by the power gear 6, the rotating speed of the inner core of the flywheel is increased, and the motor 110 can generate more electric energy under the condition of the same acceleration.
As an optional implementation of the embodiment of the present invention, the first gear 41 is fixedly connected with the second gear 42; or the first gear 41 and the second gear 42 are in gear engagement through one or more gears. To further increase the stroke of the amplifying gear set 4, in the present embodiment, the first gear 41 and the second gear 42 may be increased in stroke by one or more gear teeth. Specifically, a combination of multiple sets of small gears and large gears can be added between the first gear 41 and the second gear 42 according to actual needs, that is, a gear with a small reference circle diameter is matched with a gear with a large reference circle diameter, and the large gears are driven by the small gears to further amplify the stroke of the gear set 4. Specifically, for example, 2 sets may be added, each set including a first large gear and a first small gear, and the second set including a second large gear and a second small gear. The first gear 41 is fixedly connected to a first gearwheel in the first group, the first gearwheel is in toothed connection with a first pinion, the first pinion is fixedly connected to a second gearwheel in the second group, the second gearwheel is in toothed connection with a second pinion, and the second pinion is fixedly connected to the second gear 41. Therefore, the first gear 41 drives the first gearwheel to rotate, the first gearwheel drives the first pinion to rotate, the first pinion drives the second gearwheel to rotate, the second gearwheel drives the second pinion to rotate, and the second pinion drives the second gear 42 to rotate, so that the power gear 6 can further increase the external force applied to the flywheel, increase the rotating speed of the inner core of the flywheel, and enable the motor 110 to generate more electric energy under the condition of the same acceleration.
