[0044] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0046] like Figure 1 As shown, this utility model provides an inertial energy storage range extender system that can be applied to two-wheeled or three-wheeled electric vehicles to improve their driving range.

[0047] Specifically, the inertial energy storage range extender system includes: a three-phase brushless magnetic generator A, a rectifier and filter module, a first charger P, a battery pack, and a second charger I.

[0048] In this configuration, the rotor of the three-phase brushless magnetic generator A is connected to the transmission structure of the vehicle's driven wheel, converting the mechanical energy of the driven wheel's rotation into electrical energy. Specifically, as shown... Figure 3 As shown, the hub motor 6 of the wheel is connected to the hub motor drive shaft 7. A drive gear 8 is fixedly mounted on the hub motor drive shaft 7, and the drive gear 8 engages with a driven gear 9. The drive gear 8 and the driven gear 9 are connected by a toothed drive belt 10. The driven gear 9 is fixedly mounted on the central shaft (magnet) of the three-phase brushless magnetic generator A. The central shaft of the three-phase brushless magnetic generator A drives the rotor of the three-phase brushless magnetic generator to rotate. The transmission ratio here is 1:6.2, cutting the three-phase windings of the stator in the three-phase brushless magnetic generator A to generate three-phase AC power. In this embodiment, the drive gear 8 is a 2gt drive gear (160 teeth), the driven gear 9 is a 2gt driven gear (26 teeth), and the toothed drive belt 10 is a 2gt toothed drive belt.

[0049] The output terminal of the three-phase brushless magnetic generator A is electrically connected to the input terminal of the rectifier and filter module. The three-phase AC power output by the three-phase brushless magnetic generator A is converted into DC power by the rectifier and filter module and then rectified and filtered. In this embodiment, the rectifier and filter module includes a three-phase silicon rectifier B and a rectifier filter C. The input terminal of the three-phase silicon rectifier B is electrically connected to the output terminal of the three-phase brushless magnetic generator A, converting the three-phase AC power output by the three-phase brushless magnetic generator A into DC power. The input terminal of the rectifier filter C is connected to the output terminal of the three-phase silicon rectifier B, filtering, rectifying, and regulating the DC power output by the three-phase silicon rectifier B. The output terminal of the rectifier filter C of the rectifier and filter module is electrically connected to the input terminal of the first charger P. Specifically, in the circuit connection, the output terminal of the rectifier filter C is electrically connected to the rectifier and filter boost capacitor C3 inside the first charger P. In this embodiment, the rectifier filter C is a filter capacitor module. The positive output terminal of the three-phase silicon rectifier B is connected to the positive terminal of the filter capacitor module, and the negative output terminal of the three-phase silicon rectifier B is connected to the negative terminal of the filter capacitor module. The positive terminal of the filter capacitor module is connected to the positive terminal of the rectifier filter boost capacitor C3. Figure 1 Point E in the diagram indicates that the negative terminal of the filter capacitor module is connected to the negative terminal of the rectifier filter boost capacitor C3, i.e. Figure 1 Point D in the diagram. The output terminal of the first charger P is electrically connected to the charging terminal of the battery pack to charge the battery pack. The above structure realizes the conversion of the mechanical energy of the rear wheel rotation into electrical energy through the three-phase brushless magnetic generator A, and then rectified and filtered by the rectifier and filter module. The rectified and filtered electrical energy is then charged into the battery pack by the first charger P, thereby supplementing the battery pack of the two-wheeled or three-wheeled vehicle while it is in motion, and increasing the driving range.

[0050] In this embodiment, the first charger P is fixed inside the vehicle body. The three-phase brushless magnetic generator A has a maximum output power of 800W and a maximum output current of 1.5A-3.5A. The preferred, but not limited to, model of the three-phase silicon rectifier B is SKBPC1516. After the SKBPC1516 rectifies the three-phase AC power output from the three-phase brushless magnetic generator A, it is sent to the filter capacitor module for rectification, filtering and voltage regulation to generate a DC voltage of 225V. The 225V DC voltage is boosted by the rectifier filter boost capacitor C3 in the first charger P to obtain a DC voltage of about 310V, which can meet the charging requirements of ordinary two-wheeled electric vehicles or three-wheeled electric vehicle battery packs. In this embodiment, the three-phase brushless magnetic generator A has a maximum output power of 800W and a maximum output current of 1.5A-3.5A. The power consumption of a typical two-wheeled or three-wheeled electric vehicle charger is around 400W. The three-phase brushless magnetic generator A here can meet the energy consumption of 48V, 60V, and 72V (20AH) battery packs during riding, thereby increasing the range.

[0051] In this embodiment, a vehicle-mounted charging socket H is also provided on the vehicle body. The second charger I is connected to the mains power. When charging with mains power, the plugs of the vehicle-mounted charging socket H and the second charger I are connected, and the vehicle-mounted charging socket H is electrically connected to the battery pack. To avoid conflict between mains power charging and the aforementioned energy recovery supplementary charging, the energy recovery supplementary charging needs to be disconnected when charging with mains power. This embodiment achieves this by setting a normally closed contact structure K in the vehicle-mounted charging socket H. Specifically, the normally closed contact structure K is located on the connection line between the rectifier filter module and the first charger P. When the second charger I is inserted into the vehicle-mounted charging socket H, the normally closed contact structure K opens; otherwise, the normally closed contact structure K closes. That is, when charging with mains power, an open circuit is formed between the rectifier filter module and the first charger P, and the aforementioned energy recovery supplementary charging stops; when the second charger I is unplugged from the vehicle-mounted charging socket H, mains power charging stops, and the circuit between the rectifier filter module and the first charger P closes. When the vehicle is started, the battery pack is replenished with power to increase the driving range.

[0052] Specifically, in this embodiment, the normally closed contact structure K includes a driving block 1, which is disposed on the functional notch 2 on the side of the vehicle charging socket H. The driving block 1 is perpendicular to the plug insertion direction of the second charger I. The normally closed contact structure K also includes a rotating shaft 3 and a passage block 4 fixed on the rotating shaft 3. The passage block 4 is connected to the connection line between the rectifier filter module and the first charger P.

[0053] One end of the drive block 1 extends through the functional notch 2 and protrudes into the inner wall of the slot of the vehicle charging socket H. The part of the drive block 1 protruding into the inner wall of the slot of the vehicle charging socket H is a sphere or a hemisphere. The other end is fixedly connected to the passage block 4, and a return spring 5 is provided on the passage block 4 or the rotating shaft 3. Figure 2 As shown, the return spring 5 is connected between the outer wall of the slot where the functional notch 2 is located and the passage block 4. When the return spring 5 is set on the rotating shaft 3, a torsion spring can be used as the return spring 5.

[0054] When charging with AC power, the plug of the second charger I is inserted into the vehicle's charging socket H, and the drive block 1 is pressed (e.g., Figure 1 As shown, the leftward squeezing pushes the passage block 4, causing the rotating shaft 3 to rotate accordingly. The passage block 4 is disconnected from the connection line between the rectifier filter module and the first charger P.

[0055] When the mains charging ends, the plug of the second charger I is unplugged from the vehicle charging socket H, and the circuit block 4 is reset by the action of the reset spring 5, and reconnected to the connection line between the rectifier filter module and the first charger P, restoring the energy recovery and replenishment circuit.

[0056] In this embodiment, the circuit block 4 includes a first contact point 41 and a second contact point 42 electrically connected. Both the first contact point 41 and the second contact point 42 are fixedly connected to the rotating shaft 3, and the driving block 1 is fixedly connected to the first contact point 41. When charging with AC power, the plug of the second charger I is inserted into the vehicle charging socket H. The first contact point 41 is pushed to the left by the driving block 1, the rotating shaft 3 rotates, and the first contact point 41 is disconnected from the output terminal of the rectifier and filter module. The second contact point 42 is disconnected from the input terminal of the first charger P as the rotating shaft 3 rotates. When AC power charging ends, the plug of the second charger I is pulled out of the vehicle charging socket H. Under the action of the return spring 5, the rotating shaft 3 resets, the first contact point 41 resets, and connects to the output terminal of the rectifier and filter module. The second contact point 42 resets as the rotating shaft 3 rotates, and connects to the input terminal of the first charger P, returning to the energy recovery and replenishment circuit.

[0057] This embodiment can be used for the development and production of two-wheeled or three-wheeled electric vehicles, and can also be used to improve existing original two-wheeled or three-wheeled electric vehicles to increase their range. When used to improve an original vehicle, the second charger I is the original vehicle's matching charger, and the first charger P is a charger with the same parameters as the original vehicle's matching charger or is directly the original vehicle's matching charger, which can be purchased directly. Both contain a rectifier, filter, and boost capacitor C3.
