Thus, in the above-mentioned electric power generation device of the vehicle-mounted unit, 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, and the second gear 42 drives the power gear 6 to rotate, and at the same time, the power gear 6 applies an external force to the first external teeth 91 of the first flywheel 9 through the first transmission member 7 and an external force to the second external teeth 101 of the second flywheel 10 through the second transmission member 8, so that the first inner core (not shown in the figure) of the first flywheel 9 and the second inner core 102 of the second flywheel 10 can be rotated. The first core and the second core rotate in the same direction, and when the first core and the second 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 will be exemplarily described with respect to generating electric energy when an automobile accelerates and decelerates, respectively.
The inner core of the flywheel can rotate clockwise or anticlockwise when the external teeth are subjected to clockwise external force according to the characteristics of the flywheel. Since the first flywheel 9 and the second flywheel 10 are reverse flywheels in this embodiment, the rotation directions of the first inner core and the second inner core 102 are the same. Hereinafter, the embodiment of the present invention will be described taking a case where the first inner core rotates clockwise when the first flywheel 9 receives a clockwise external force and taking a case where the second inner core 102 rotates clockwise when the second flywheel 10 receives a counterclockwise external force.
In one example application, an automobile is described as an example in which the automobile starts accelerating and then decelerating. When the vehicle starts accelerating, the pendulum 24 swings backward, driving the sector 22 to swing forward, both the first gear 41 and the second gear 42 of the accelerating gear set 4 rotate clockwise (clockwise or counterclockwise herein refers to the direction of rotation as viewed from the perspective of the power pendulum 2 toward the motor 110), and driving the power gear 6 to rotate clockwise, and at the same time, 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 flywheel, the first core of the first flywheel 9 starts to rotate clockwise, and at this time, the second core 102 of the second flywheel 10 does not rotate due to the external force, but because both the second core 102 and the first core are fixedly connected with the third pivot shaft 5, the second core 102 starts to rotate under the driving of the first core. The clockwise rotation of the first core of the first flywheel 9 may cause the rotor 1101 to rotate clockwise, thereby generating electric power. When the automobile decelerates in the process of traveling after acceleration, the pendulum 24 swings forwards to drive the sector part 22 to swing backwards, gears of the acceleration gear set 4 rotate anticlockwise and drive the power gear 6 to rotate anticlockwise, meanwhile, anticlockwise external force is applied to the first external teeth 91 of the first flywheel 9 through the first transmission part 7 by the anticlockwise power gear 6, anticlockwise external force is applied to the second external teeth 101 of the second flywheel 10 through the second transmission part 8, according to the characteristics of the flywheel, the first inner core of the first flywheel 9 still keeps rotating clockwise after the first external teeth are subjected to anticlockwise external force, the second inner core 102 of the second flywheel 10 rotates clockwise when the second external teeth 101 are subjected to anticlockwise external force, and the first inner core and the second inner core 102 rotate clockwise and drive the rotor 1101 to rotate continuously, so that electric energy can still be generated when the automobile decelerates after acceleration.
In another application example, when the vehicle starts decelerating and then accelerates, the operation principle is basically the same as that of the above application example, except that the directions are opposite. Only briefly described here. When the automobile is decelerating, the power gear 6 rotates anticlockwise, and applies anticlockwise external force to the first external teeth 91 and the second external teeth 101 respectively, and 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 during the running after deceleration, the power gear 6 rotates clockwise, applying a clockwise external force to the first external teeth 91 and the second external teeth 101 respectively, and according to the characteristics of the flywheel, the second inner core 102 of the second flywheel 10 still keeps rotating clockwise, while the first inner core of the first flywheel 9 rotates clockwise when the first external teeth 101 are subjected to the clockwise external force, thereby 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 accelerating again after deceleration.
By arranging the first flywheel and the second flywheel, the external force can be applied to the flywheels no matter the automobile accelerates or decelerates, so that the inner cores of the two flywheels can rotate in the same direction, the rotating speed of the rotor 1101 can be kept, and the motor 110 can continuously generate electric energy.
The distance between the pendulum bob 24 and the first through hole 25 is smaller than the distance between the sector part 22 and the first through hole 25, and accords with a first preset proportion, the first preset proportion can be set according to actual needs, and under the condition of meeting the size requirement, the distance between the sector part 22 and the first through hole 25 is made to be larger than the distance between the pendulum bob 24 and the first through hole 25 as much as possible, so that the stroke of the sector part 23 can be increased, the external force applied to the flywheel can be increased by the power gear 6, the rotating speed of the flywheel inner core is increased, and more electric energy can be generated by the motor 110 under the condition of the same acceleration.
In addition, in order to increase the stroke of the pendulum 24, as an alternative implementation of the embodiment of the present invention, the pendulum 24 includes an extension member 26, the extension member 26 is disposed perpendicularly to the link 21, the end of the extension 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 is disposed corresponding to the first through hole 25 in the extending direction of the first pivot shaft 1. Thereby structurally increasing the volume of the pendulum 24 and increasing its weight, and in the acceleration and deceleration movements of the vehicle, the stroke of the pendulum 24 can be increased, and at the same time, the electric power generation device of the vehicle-mounted unit can be installed conveniently at the time of subsequent installation.
As an alternative implementation manner of the embodiment of the present invention, the extension part 26 and the flywheel, the motor and other parts are arranged 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 vehicle-mounted unit can be reduced.
In order to increase the travel of the amplifying gear set 4, as an alternative to the embodiment of the invention, the pitch diameter of the first gear 41 is smaller than the pitch diameter of the second gear 42 and corresponds to a second preset ratio. The second preset ratio may be set according to actual needs, and in the case of meeting the size requirement, the pitch diameter of the second gear 42 is made larger than the pitch diameter of the first gear 41 as much as possible, so that the stroke of the amplifying gear set 4 may be increased, further the power gear 6 may increase the external force applied to the flywheel, and increase the rotational speed of the flywheel inner core, so that the motor 110 generates more electric energy under the same acceleration.
As an alternative 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 toothed through one or more gears. To further increase the stroke of the amplifying gear set 4, in this embodiment, the first gear 41 and the second gear 42 may be increased by one or more gear teeth. Specifically, a plurality of groups of combinations of small gears and large gears can be added between the first gear 41 and the second gear 42 according to actual needs, namely, the small-diameter gear of the reference circle is matched with the large-diameter gear of the reference circle, and the large gears are driven by the small gears, so that the stroke of the amplifying gear set 4 is further amplified. Specifically, for example, 2 groups each including a first large gear and a first small gear and a second group including a second large gear and a second small gear may be added. Wherein, first gear 41 is connected with first gear wheel in the first group, and first gear wheel is in tooth joint with first pinion, and first pinion is connected with second gear wheel in the second group, and second gear wheel is in tooth joint with second pinion, and second pinion is connected with second gear 41 fixed. Thus, the first gear 41 drives the first large gear to rotate, the first large gear drives the first small gear to rotate, the first small gear drives the second large gear to rotate, the second large gear drives the second small gear to rotate, and the second small gear 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 flywheel inner core, and enable the motor 110 to generate more electric energy under the condition of the same acceleration.
