[0033] The following is a detailed description of this application.

[0034] This application proposes a driving device, with reference to... Figure 1 As shown, Figure 1 A schematic diagram of the driver provided in this application.

[0035] In this embodiment, as Figure 1 As shown, the drive device includes a motor 10, a first drive gear 11, an engine 12, a first driven gear 13, a second drive gear 14, and a clutch dog gear 15. The first drive gear 11 is disposed on the motor 10 and meshes with the first driven gear 13. The first driven gear 13 and the second drive gear 14 are both disposed on the engine 12. The clutch dog gear 15 has three position states relative to the engine 12, or the clutch dog gear 15 has two position states relative to the engine 12. When the clutch dog gear 15 has three position states, the drive device can realize motor direct drive mode, neutral mode, generator mode, and engine direct drive mode. When the clutch dog gear 15 has two position states, the drive device can realize motor direct drive mode and engine direct drive mode.

[0036] In this embodiment, when the clutch dog tooth 15 has three position states, the drive device can realize motor direct drive mode, neutral mode, generator mode, and engine direct drive mode. When the clutch dog tooth 15 has two position states, the drive device can realize motor direct drive mode and engine direct drive mode. This device can freely switch between motor direct drive mode, neutral mode, generator mode, and engine direct drive mode, effectively improving the flexibility and economy of the electrical device during use. By using the engagement of a single clutch dog tooth to couple different components, it avoids the disadvantages of traditional two or more clutches in different positions, resulting in a simple structure and effectively reducing development costs.

[0037] In some embodiments, the motor 10 is provided with a first output shaft 101, and a first drive gear 11 is fixed to the first output shaft 101; the engine 12 is provided with a second output shaft 121, and an engine shaft dog tooth 122 is provided on the second output shaft 121; a first driven gear 13 and a second drive gear 14 are both provided on the second output shaft 121, the first driven gear 13 is provided with a first dog tooth 131, and the first driven gear 13 meshes with the first drive gear 11; the second drive gear 14 is provided with a second dog tooth 141, and the second dog tooth 141 and the first dog tooth 131 are located on both sides of the engine shaft dog tooth 122 along the axial direction;

[0038] When the clutch dog tooth 15 has three position states, the clutch dog tooth 15 is configured to engage with the first dog tooth 131 and the second dog tooth 141, or; the clutch dog tooth 15 is not engaged with the first dog tooth 131 and the engine shaft dog tooth 122, or; the clutch dog tooth 15 is configured to engage with the first dog tooth 131 and the engine shaft dog tooth 122, or; the clutch dog tooth 15 is configured to engage with the engine shaft dog tooth 122 and the second dog tooth 141.

[0039] When the clutch dog tooth 15 has two position states, the clutch dog tooth 15 is configured to engage with the first dog tooth 131 and the second dog tooth 141, or the clutch dog tooth 15 is configured to engage with the engine shaft dog tooth 122 and the second dog tooth 141.

[0040] In this embodiment, the first driving gear 11 and the first output shaft 101 can be connected together by keys, bolts, etc. The specific connection can be determined according to the actual situation, and this embodiment does not limit this connection.

[0041] In this embodiment, the first dog tooth 131 is integrally formed with the first driven gear 13, the second dog tooth 141 is integrally formed with the second driving gear 14, and the engine shaft dog tooth 122 is integrally formed with the second output shaft 121.

[0042] refer to Figure 1As shown, when the clutch dog tooth 15 is engaged with the first dog tooth 131 and the second dog tooth 141, and the clutch dog tooth 15 is not engaged with the engine shaft dog tooth 122, this mode is the direct drive mode of the motor 10. At this time, the power generated by the engine 12 cannot be transmitted to the second drive gear 14. The motor 10 drives the second drive gear 14 to rotate and do work through the first drive gear 11, the first driven gear 13, the first dog tooth 131, the clutch dog tooth 15, and the second dog tooth 141.

[0043] When the clutch dog tooth 15 is not engaged with the first dog tooth 131 and the engine shaft dog tooth 122, the power of the motor 10 and the engine 12 cannot be transmitted to the second drive gear 14, and this is the neutral mode.

[0044] When the clutch dog tooth 15 is engaged with the first dog tooth 131 and the engine shaft dog tooth 122, and the clutch dog tooth 15 is not engaged with the second dog tooth 141, this mode is the power generation mode. At this time, the engine 12 generates electricity by reversing the motor 10 through the engine shaft dog tooth 122, the clutch dog tooth 15, the first dog tooth 131, the first driven gear 13, and the first driving gear 11.

[0045] When the clutch dog tooth 15 is engaged with the engine shaft dog tooth 122 and the second dog tooth 141, and the clutch dog tooth 15 is not engaged with the first dog tooth 131, this mode is the direct drive mode of the engine 12. At this time, the engine 12 drives the second drive gear 14 to rotate and do work through the engine shaft dog tooth 122, the clutch dog tooth 15, and the second dog tooth 141.

[0046] This device can freely switch between motor direct drive mode, neutral mode, generator mode and engine direct drive mode, effectively improving the flexibility and economy of the electrical device during use; the coupling of different components is achieved through the meshing of a clutch dog tooth, avoiding the disadvantages of traditional two or more clutches in different positions, the structure is simple and effectively reduces development costs.

[0047] In some embodiments, such as Figure 2 As shown, the drive device also includes a second driven gear 16, a half shaft 18 and a rotating wheel 19, wherein the rotating wheel 19 is disposed at the end of the half shaft 18, the second driven gear 16 is sleeved on the half shaft 18, and the second driven gear 16 meshes with the second driving gear 14.

[0048] In use, the second driven gear 16 is driven to rotate by the second driving gear 14, and the second driven gear 16 can drive the rotating wheel 19 to rotate by passing through the half shaft 18.

[0049] In some embodiments, such as Figure 2 As shown, the drive device also includes an idler gear 20, which meshes with the second drive gear 14 and the second driven gear 16 respectively.

[0050] In this embodiment, an idler gear 20 is added between the first driven gear 13 and the second driven gear 16, thereby enabling flexible adjustment of the distance between the second output shaft 121 and the half shaft 18, so as to quickly adapt to different engines and vehicle models.

[0051] In some embodiments, such as Figure 3 As shown, the drive device also includes a transmission gear 21, which is coaxially arranged with the idler gear 20. The idler gear 20 meshes with the second driven gear 16 through the transmission gear 21.

[0052] This embodiment adds a transmission gear 21 between the idler gear 20 and the second driven gear 16, thereby enabling flexible configuration of the speed ratio to quickly adapt to different engines and vehicle models.

[0053] In some embodiments, the drive unit further includes a differential 17 disposed on the half-shaft 18, and a second driven gear 16 disposed on the differential 17.

[0054] When a vehicle turns, the inner wheel travels a shorter trajectory than the outer wheel. By incorporating a differential 17, which, through its internal planetary gear set, allows the left and right wheels 19 to rotate at different speeds, the differential 17 prevents tire slippage or wear due to forced synchronization, ensuring smooth turning.

[0055] In some embodiments, the first drive gear 11 is connected to the first output shaft 101 by a key.

[0056] In this embodiment, an internal spline can be provided on the first driving gear 11 and an external spline can be provided on the first output shaft 101. The cooperation of the internal and external splines can make the first driving gear 11 stably connected to the first output shaft 101.

[0057] In some embodiments, the drive unit further includes a battery assembly electrically connected to the motor 10. This facilitates the battery assembly to drive the motor 10, or, in battery charging mode, facilitates charging the battery assembly.

[0058] In some embodiments, the drive unit further includes a battery management system electrically connected to the battery assembly and configured to monitor the charge, temperature and voltage of the battery assembly.

[0059] The Battery Management System (BMS) in this embodiment is the core control system in electric vehicles, battery packs, and all devices using rechargeable batteries. For details, please refer to existing battery management systems, which will not be elaborated here.

[0060] This implementation facilitates the monitoring of battery module charge, temperature, and voltage by setting up a battery management system.
