Description

Technical Field

[0001] This invention relates to the field of power device technology, and in particular to a power device equipped with a switching output shaft. Background Technology

[0002] In traditional fuel-powered lawnmowers, the engine's main power output shaft and drive shaft are usually coaxially and linearly fixedly connected. This coaxial linear fixed structure is only suitable for installation on certain older, fixed models of lawnmowers.

[0003] Because existing coaxial linear combustion engines are not well-suited for compatible installation of various devices in reverse orientation (horizontal or vertical), they are unable to meet the demands as lawnmower designs continue to evolve, especially lacking a drive shaft output perpendicular to the main power output shaft. Furthermore, the existing combustion engines are not suitable as power supply devices for other devices and cannot adapt to the ever-increasing demands of various applications, thus requiring further improvement. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a power device equipped with a switching output shaft, which can provide power outputs perpendicular to or coaxial with the main power output shaft, facilitating switching as needed, and offering convenient installation and connection with a wide range of applications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A power unit with a switching output shaft includes an engine body, a power main shaft within the engine body, a mounting connection surface on the engine body, and a main drive shaft component on the mounting connection surface. The main drive shaft component includes a mounting base, a main gear, a steering gear, a main output shaft, and an extended mounting seat. The mounting base is fixed to the mounting connection surface. The main gear is mounted on the power main shaft. The steering gear is located at the input shaft end of the main output shaft and can dynamically mesh with the main gear. The mounting base has a bearing mounting slot, and two main bearings are provided between the bearing mounting slot and the extended mounting seat to support the main output shaft.

[0006] Furthermore, the main gear and the steering gear are a paired bevel gear set.

[0007] Furthermore, the extended mounting base is provided with a second transmission shaft component, which includes a second output shaft, a second bearing, and a clutch device. The power spindle is provided with a bushing connected to one end of the clutch device, and the other end of the clutch device is connected to the second output shaft. The clutch device is used to rotatably connect or disconnect the second output shaft from the power spindle. The second bearing is provided in the extended mounting base to support the second output shaft.

[0008] Furthermore, the steering gear is slidably sleeved on the main output shaft, and the mounting base is provided with an electric actuator for pushing the steering gear closer to or away from the main gear. When the clutch device rotates the second output shaft to the power main shaft, the electric actuator pushes the steering gear to separate from the main gear. When the electric actuator pushes the steering gear to mesh with the main gear, the clutch device disengages the second output shaft from the power main shaft.

[0009] Furthermore, the extended mounting base is equipped with a controller connected to the clutch device and the electric actuator.

[0010] Furthermore, the extended mounting base is provided with a bearing positioning hole for mounting the second bearing.

[0011] Furthermore, the second bearing comprises two bearings, with a spacer between the two bearings, and the second output shaft is provided with a bearing locking nut.

[0012] Furthermore, a removable protective cover is provided on the outside of the second output shaft.

[0013] The present invention has the following beneficial effects: 1. The present invention includes a main drive shaft component and a second drive shaft component. The main output shaft in the main drive shaft component can be dynamically meshed perpendicularly with the main gear on the power main shaft through a steering gear. The second output shaft in the second drive shaft component can be dynamically connected coaxially with the power main shaft through a clutch device. The main output shaft and the second output shaft can be switched as needed. The installation and connection are convenient, and the application range is wide. It is very suitable as a multifunctional power supply device for various small devices.

[0014] 2. The present invention installs the second drive shaft component by setting an extended mounting base. The second drive shaft component is equipped with an automatically controllable clutch device. The clutch device can be linked with the electric actuator that pushes the steering gear close to or away from the main gear for easy use. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1:

[0022] See Figure 1 and Figure 4 As shown, a power device with a switching output shaft includes an engine body 1, a power main shaft 11 in the engine body 1, a mounting connection surface 12 on the engine body 1, a main drive shaft component 2 on the mounting connection surface 12, the main drive shaft component 2 including a mounting base 21, a main gear 22, a steering gear 23, a main output shaft 24 and an extended mounting seat 25, the mounting base 21 being fixed to the mounting connection surface 12, the main gear 22 being mounted on the power main shaft 11, and the steering gear 23 being mounted on the input shaft end of the main output shaft 24 and capable of dynamically meshing with the main gear 22 (in this embodiment, if only one main output shaft 24 is provided, the steering gear 23 can also directly mesh with the main gear 22, in which case the extended mounting seat 25 can be simplified in design), the main gear 22 and the steering gear 23 being a paired bevel gear set, the mounting base 21 having a bearing mounting slot 211, and two main bearings 26 being provided between the bearing mounting slot 211 and the extended mounting seat 25 to support the main output shaft 24. Example 2:

[0023] See Figure 2-5As shown, based on Embodiment 1, a second transmission shaft component 3 is provided on the extended mounting base 25. The second transmission shaft component 3 includes a second output shaft 31, a second bearing 32, and a clutch device 33. A bushing 13 is provided on the power main shaft 11 and connected to one end of the clutch device 33. The other end of the clutch device 33 is connected to the second output shaft 31. The clutch device 33 is used to rotatably connect or disconnect the second output shaft 31 from the power main shaft 11. The second bearing 32 is provided in the extended mounting base 25 to support the second output shaft 31. The clutch device 33 can be electrically or manually operated, and its specific structure refers to the prior art. Sufficient internal installation space is provided between the mounting base 21 and the extended mounting base 25 for installing the above-mentioned components.

[0024] Furthermore, an electric actuator 27 is provided in the mounting base 21, on which the steering gear 23 is slidably sleeved on the main output shaft 24. The electric actuator 27 pushes the steering gear 23 closer to or away from the main gear 22. When the clutch device 33 rotates the second output shaft 31 to the power main shaft 11, the electric actuator 27 pushes the steering gear 23 to separate from the main gear 22. When the electric actuator 27 pushes the steering gear 23 to mesh with the main gear 22, the clutch device 33 disengages the second output shaft 31 from the power main shaft 11. The extended mounting base 25 is externally provided with a controller 34 connected to the clutch device 33 and the electric actuator 27. The controller 34 is connected to a power supply (such as a rechargeable battery). The structure of the electric actuator 27 is designed with reference to existing technology, including an electromagnet that drives the steering gear 23. The extended mounting base 25 is provided with a bearing positioning hole 251 for mounting the second bearing 32, and the extended mounting base 25 is also provided with a bearing groove corresponding to the bearing mounting slot 211 for fixing two main bearings 26. Two second bearings 32 are provided, with a spacer between the two second bearings 32, and a bearing locking nut 35 is provided on the second output shaft 31. A removable protective cover 36 is provided on the outside of the second output shaft 31. The protective cover 36 can be removed when the second output shaft 31 is working; when the second output shaft 31 is not working, the protective cover 36 is put on for protection.

[0025] For a simplified design, the clutch device 33 and the electric actuator 27 can be replaced by a manually operated mechanical clutch mechanism, using manual switching. If necessary, the main output shaft 24 and the second output shaft 31 can be modified to be simultaneously connected to the power main shaft 11, allowing both output shafts to drive the load concurrently.

[0026] The above description is merely a specific embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
