[0028] like Figure 1-5As shown, in one embodiment of this utility model, a multi-motor engine is provided, including a power unit 10, a first gear 20, multiple second gears 30, and multiple motor bodies 40. The power unit 10 has a first output shaft 11, a first chamber, and a second chamber. The first output shaft 11 is a crankshaft that extends into the first chamber. The first gear 20 is located in the first chamber and connected to the first output shaft 11. The multiple second gears 30 are located in the first chamber and are respectively connected to the first gear 20 for transmission. The diameter of the second gears 30 is smaller than the diameter of the first gears 20. The multiple motor bodies 40 are located in the second chamber, and each motor body 40 is connected to one second gear 30.

[0029] The first output shaft 11 drives the first gear 20, which in turn rotates multiple second gears 30, thereby increasing the speed of the second gears 30. This achieves high-speed output without changing the rotational speed of the first output shaft 11, reducing wear on moving parts inside the power unit 10 housing, lowering overall fuel consumption, and extending the overall service life of the machine. Simultaneously, the second gears 30 also drive the rotor of the motor body 40 to rotate at high speed, improving power generation conversion efficiency and further saving energy and costs.

[0030] Because this engine uses a multi-motor structure, the motor body 40 is smaller in size than that of a conventional engine, making the overall structure more compact and significantly reducing the size, weight and cost of engines with the same displacement.

[0031] In summary, the multi-motor engine disclosed in this embodiment can improve the overall performance and power of the engine without changing the rotational speed of the first output shaft 11, thereby saving energy efficiency and cost. Furthermore, optimizing the traditional single-motor structure into a multi-motor structure can improve the overall fault tolerance and reduce the size, weight, and cost of engines with the same displacement.

[0032] In one embodiment, a plurality of second output shafts 12 are rotatably mounted on the power unit 10, and each second gear 30 is mounted on a corresponding second output shaft 12. The second output shaft 12 extends into the second chamber and is connected to the corresponding motor body 40. When the power unit 10 is running, the rotation of the first output shaft 11 drives the first gear 20 to make the second gear 30 and the second output shaft 12 rotate synchronously. Since the diameter of the second gear 30 is smaller than the diameter of the first gear 20, the speed of the second gear 30 and the second output shaft 12 is increased without changing the speed of the first output shaft 11. This allows the rotor of the motor body 40 to rotate at a high speed, thereby improving the power generation conversion efficiency and saving energy and costs.

[0033] In one embodiment, the power unit 10 includes a first housing 13, a second housing 14, and a third housing 15. The first housing 13 and the second housing 14 are connected to form a first chamber, and the third housing 15 is located on the side of the second housing 14 opposite to the first housing 13. The third housing 15 is connected to the second housing 14 to form a second chamber. This structural design facilitates the assembly and disassembly of the first gear 20, the second gear 30, and the motor body 40.

[0034] In one embodiment, the third housing 15 is provided with a plurality of exhaust vents 151, which are connected to the second chamber. Each exhaust vent 151 corresponds to a motor body 40. Each second output shaft 12 is also equipped with an impeller (not shown in the figure). The impeller is located in the second chamber. When the second output shaft 12 rotates, the impeller will conduct the heat in the second chamber through the second exhaust vent 151, thereby effectively reducing the temperature of the motor body 40 and enabling it to operate under normal working conditions.

[0035] In one embodiment, to ensure that external airflow can smoothly enter the second chamber, the third housing 15 is provided with a plurality of air inlets 152.

[0036] In one embodiment, the second housing 14 or the third housing 15 is provided with two first supports 153. The design of the first supports 153 is to support other components, facilitating their installation. The bottom of the second housing 14 or the third housing 15 is provided with two second supports 154. The design of the second supports 154 is to provide better support for the entire machine during installation. In this embodiment, both the first supports 153 and the second supports 154 are located on the third housing 15.

[0037] In one embodiment, the first housing 13 is provided with two oil holes 131, which communicate with the first chamber. Engine oil in the crankcase can enter the first chamber through the oil holes 131, thereby lubricating the first gear 20 and the second gear 30 and ensuring their normal operation.

[0038] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
