Description

Technical Field

[0001] This utility model relates to the field of power drive technology, and in particular to a hybrid power device. Background Technology

[0002] In the international context of addressing climate change, reducing greenhouse gas emissions has become an undeniable responsibility for humanity. As a high-energy-consuming and high-polluting industry in my country, construction and transportation equipment is also forced to begin researching and utilizing low-carbon technologies under the multiple pressures of climate change, energy shortages, and energy security concerns. With the country's increasing emphasis on energy conservation and emission reduction, it is gradually phasing out high-emission, high-noise equipment. Especially given the rapid pace of urban development, the use of low-emission and low-noise equipment is even more crucial in urban construction.

[0003] The patent application number "CN202410674741.1" discloses a "hybrid power device and vehicle" that can be powered by an engine or an electric drive device, but the structure of the device is relatively complex and not easy to promote. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and realize hybrid power output of the engine and / or motor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hybrid power device includes an electric motor for outputting power and providing power, the electric motor being connected to a clutch, the clutch being connected to an engine that can provide power.

[0007] Preferably, the clutch includes a flywheel receiving plate and a clutch shaft that can engage with the flywheel receiving plate for transmission, and the clutch shaft is also connected to a disengagement mechanism that drives its reciprocating movement.

[0008] Preferably, the flywheel receiving plate has a first tooth, the first tooth having a first tooth slope, and the clutch shaft has a second tooth meshing with the first tooth, the second tooth having a second tooth slope engaging with the first tooth slope.

[0009] Preferably, the first gear tooth is an internal gear, and the second gear tooth is an external gear.

[0010] Preferably, the output shaft of the engine is connected to the flywheel plate.

[0011] Preferably, the motor shaft has a third gear tooth, and the clutch shaft has a fourth gear tooth that meshes with the third gear tooth.

[0012] Preferably, the third gear tooth extends axially along the motor shaft.

[0013] Preferably, the third gear tooth is an external gear, and the fourth gear tooth is an internal gear.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The engine, clutch and motor are connected in series. This structural arrangement makes the equipment uniformly stressed, lightweight, spacious, and easy to install and maintain.

[0016] 2. The engine is located at the center line of the front end of the device, which is easy to install and maintain, and improves maintenance efficiency.

[0017] 3. The drive system, consisting of an electric motor, engine, and clutch, can efficiently convert the engine's power into driving force for the transportation equipment.

[0018] 4. The device can be powered directly by AC power supplied from the site, which effectively reduces emissions and noise pollution.

[0019] 5. By moving the second gear in the clutch, the connection between the clutch and the engine can be disconnected, and the engine no longer provides power. At this time, the electric motor provides power. When the second gear moves in the opposite direction, the first gear and the second gear can mesh smoothly through the tooth helical surface, so that the engine and the clutch can be connected. The engine can provide power alone or the engine and the electric motor can work together to provide power. Attached Figure Description

[0027] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 As shown, a hybrid power device according to this embodiment includes a motor 3 for outputting power and providing power, the motor 3 is connected to a clutch 2, and the clutch 2 is connected to an engine 1 that can provide power.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the clutch 2 includes a flywheel receiving plate 4 and a clutch shaft 5 that can engage with the flywheel receiving plate 4 for transmission. The clutch shaft 5 is also connected to a disengagement mechanism 7 that drives its reciprocating movement. The output shaft of the engine 1 is connected to the flywheel receiving plate 4.

[0032] The separation mechanism 7 can push the clutch shaft 5 to reciprocate. When it moves to the left, the clutch shaft 5 engages with the flywheel contact plate 4, and the engine 1 can drive the clutch shaft 5 to rotate through the flywheel contact plate 4. When it moves to the right, the clutch shaft 5 disengages from the flywheel contact plate 4, and the rotation of the clutch shaft 5 will not affect the engine 1.

[0033] like Figure 5 As shown, the flywheel receiving plate 4 has a first gear tooth 41, and a first tooth inclined surface 411 is provided on the first gear tooth 41. The clutch shaft 5 has a second gear tooth 51 that meshes with the first gear tooth 41, and a second tooth inclined surface 511 that cooperates with the first tooth inclined surface 411 is provided on the second gear tooth 51.

[0034] The first gear tooth 41 is an internal gear, and the second gear tooth 51 is an external gear.

[0035] During the process of the clutch shaft 5 moving to the left and engaging with the flywheel receiving plate 4, the first tooth inclined surface 411 and the second tooth inclined surface 511 first come into contact to achieve initial engagement. Then, through the rotation of the clutch shaft 5, the first gear tooth 41 and the second gear tooth 51 are fully engaged.

[0036] like Figure 6 and Figure 7 As shown, the motor shaft 6 has a third gear tooth 61, and the clutch shaft 5 has a fourth gear tooth 52 that meshes with the third gear tooth 61.

[0037] The third gear 61 extends along the axial direction of the motor shaft 6.

[0038] The third gear tooth 61 is an external gear, and the fourth gear tooth 52 is an internal gear.

[0039] When the clutch shaft 5 moves left and right under the drive of the disengagement mechanism 7, the fourth gear tooth 52 always remains engaged with the third gear tooth 61.

[0040] This device has the following three operating modes:

[0041] 1. When there is no power supply, the clutch shaft 5 engages with the flywheel plate 4. The engine 1 (driven by oil supply from the fuel tank or by air supply) drives the clutch shaft 5 to rotate through the flywheel plate 4. The clutch shaft 5 drives the motor shaft 6 to rotate to drive the motor 3. At this time, the motor 3 itself does not provide power, but the motor 3 outputs the power of the engine 1.

[0042] 2. When power is supplied, the clutch shaft 5 is disengaged from the flywheel plate 4, and the motor 3 (which can be powered by a cable or a battery) provides power and outputs the power of the motor 3. At this time, the rotation of the motor shaft 6 will not be transmitted to the engine 1.

[0043] Third, when high torque is required, the engine and motor drive simultaneously. The clutch shaft 5 engages with the flywheel plate 4. The engine 1 drives the clutch shaft 5 to rotate via the flywheel plate 4. The clutch shaft 5 then drives the motor shaft 6 to rotate, thus driving the motor 3. At this time, the motor 3 itself also provides power, simultaneously outputting power from both the engine 1 and the motor 3. In this mode, a power source is required to provide electricity.

[0044] Compared with existing technologies, this device not only has good overall safety (reasonable stress distribution) but also meets the usage requirements of each component and provides a good working space for the installation and maintenance of the equipment.

[0045] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way.
