[0018] In order to facilitate understanding of the present invention by those skilled in the art, the present invention will be further described below in combination with examples and drawings, but the contents described in the embodiments are not intended to limit the present invention. Hereinafter, the present invention will be described in detail with reference to the drawings.

[0019] With the development of science and technology, power machines are increasingly applied in industrial fields, and as part of industrial equipment, power machines can serve as energy supply components. In the prior art, a power machine includes a power component and multiple drive wheels, and the power component operates under the action of an external force to drive the multiple drive wheels to rotate relative to their mounting seats. At this time, the multiple drive wheels are transmitted by gears, and stop immediately when the gears stop. However, the inertia of the multiple drive wheels cannot be utilized due to the gears meshing with each other.

[0020] The purpose of the present invention is to provide a power machine 100 that solves the problem in the prior art that the inertial effect of multiple driving wheels cannot be utilized due to the intermeshing of multiple gears.

[0021] First Example Please refer to Figures 1 to 7. The power machine 100 according to this embodiment includes a mounting base 10, two drive wheels 20, a traction assembly 30, and a power assembly 40. The mounting base 10 functions as a support component for the power machine 100, and supports the two drive wheels 20, the traction assembly 30, and the power assembly 40. In this case, the mounting base 10 may be an outer shell of the power machine 100, or may be a frame of the power machine 100.

[0022] When the mounting base 10 is the frame of the power machine 100, the power assembly 40 is disposed on the top of the mounting base 10, and the two driving wheels 20 and the traction assembly 30 are both disposed on the sides of the mounting base 10.

[0023] The two drive wheels 20 rotate relative to the mounting seat 10. In this case, the two drive wheels 20 are rotatably attached to the mounting seat 10, and rotate relative to the mounting seat 10 due to the action of an external force.

[0024] Of these, the two drive wheels 20 are each connected to a first rotating shaft 21, and the two first rotating shafts 21 are rotatably mounted on the mounting seat 10. The two first rotating shafts 21 pass through the mounting seat 10 and are connected to the mounting seat 10 via bearings. The two first rotating shafts 21 rotate along their own axes, thereby rotating the two drive wheels 20 along the axes of the corresponding first rotating shafts 21.

[0025] The traction assembly 30 is connected to the two drive wheels 20, thereby rotating the two drive wheels 20. In this case, the traction assembly 30 includes a first transmission module 31, a second transmission module 32, and a second rotating shaft 33. The second rotating shaft 33 functions as an intermediate part of the traction assembly 30, and is rotatably mounted on the mounting seat 10 and rotates along its axis.

[0026] The second rotating shaft 33 is connected to one end of the first transmission module 31 and one end of the second transmission module 32, and the other end of the first transmission module 31 and the other end of the second transmission module 32 are connected to the respective first rotating shafts 21, thereby synchronously rotating the two driving wheels 20. The first transmission module 31 is a synchronous belt transmission module, and the second transmission module 32 is a chain transmission module.

[0027] Here, the two driving wheels 20 rotate relative to the mounting seat 10. The two driving wheels 20 are respectively connected to first rotating shafts 21, and the two first rotating shafts 21 are rotatably mounted on the mounting seat 10. The traction assembly 30 includes a first transmission module 31, a second transmission module 32, and a second rotating shaft 33. The second rotating shaft 33 is connected to one end of the first transmission module 31 and one end of the second transmission module 32, and the other end of the first transmission module 31 and the other end of the second transmission module 32 are connected to the respective first rotating shafts 21, thereby causing the two driving wheels 20 to rotate synchronously. The first transmission module 31 is a synchronous belt transmission module, and the second transmission module 32 is a chain transmission module. In this case, the first transmission module 31 acts on the second rotating shaft 33 and the first rotating shaft 21, and the second transmission module 32 acts on the second rotating shaft 33 and the first rotating shaft 21, so that the second rotating shaft 33 connects the two driving wheels 20, and the synchronous rotation of the two driving wheels 20 is ensured by the cooperation of the second rotating shaft 33, the first transmission module 31, and the second transmission module 32. Furthermore, the inertia of the second rotating shaft 33, the first transmission module 31, and the second transmission module 32 is effectively utilized, thereby increasing the rotation speed of the two driving wheels 20.

[0028] In this case, the first transmission module 31 is a synchronous belt transmission module, and the second transmission module 32 is a chain transmission module. The first transmission module 31 and the second transmission module 32 are both transmission components that act on the second rotating shaft 33, the two first rotating shafts 21, and the two driving wheels 20. As a result, the two driving wheels 20 rotate synchronously, and the inertia of the two driving wheels 20 is fully utilized under the drive of the first transmission module 31 and the second transmission module 32, avoiding the restriction of the two driving wheels 20 by gears. Therefore, even when the power assembly 40 is stopped, the two driving wheels 20 can be continuously driven. Furthermore, the inertia of the second rotating shaft 33, the first transmission module 31, and the second transmission module 32 is effectively utilized, thereby increasing the rotation speed of the two driving wheels 20.

[0029] In the above description, as a further embodiment, the first transmission module 31 and the second transmission module 32 are spaced apart along the axis of the second rotating shaft 33. In this case, the first transmission module 31 and the second transmission module 32 are spaced apart along the left-right direction, and the first transmission module 31 and the second transmission module 32 do not interfere with each other. This ensures that the first transmission module 31 and the second transmission module 32 operate independently.

[0030] Since the first transmission module 31 and the second transmission module 32 are both connected to the second rotating shaft 33, the second rotating shaft 33 acts in conjunction with the first transmission module 31 and the second transmission module 32 to ensure synchronous rotation of the two driving wheels 20, and effectively utilize the inertia of the second rotating shaft 33, the first transmission module 31, and the second transmission module 32 to improve the rotation speed of the two driving wheels 20.

[0031] Here, the first transmission module 31 includes a first synchronous pulley 311, a second synchronous pulley 312, and a first synchronous belt 313. The first synchronous pulley 311 is fitted to the first rotating shaft 21, the second synchronous pulley 312 is fitted to the second rotating shaft 33, and the first synchronous belt 313 pulls the first synchronous pulley 311 and the second synchronous pulley 312. In this case, the first synchronous belt 313 is fitted to the first synchronous pulley 311 and the second synchronous pulley 312, thereby transmitting power between the first synchronous pulley 311 and the second synchronous pulley 312.

[0032] Here, the pulley diameter of the second synchronizer pulley 312 is larger than the pulley diameter of the first synchronizer pulley 311, and the weight of the second synchronizer pulley 312 is larger than the weight of the first synchronizer pulley 311. The second synchronizer pulley 312 is connected to the second rotating shaft 33, and the greater the mass of the second synchronizer pulley 312, the greater the inertia effect. This makes more effective use of the inertia effect of the second synchronizer pulley 312, and further makes effective use of the inertia effects of the second rotating shaft 33, the first transmission module 31, and the second transmission module 32, thereby increasing the rotation speed of the two drive wheels 20.

[0033] In this case, the second synchronizer pulley 312 is keyed to the second rotating shaft 33, thereby realizing a fixed connection between the second synchronizer pulley 312 and the second rotating shaft 33. The inertial force of the second synchronizer pulley 312 is transmitted to the second rotating shaft 33 and further transmitted to the two driving wheels 20 via the second rotating shaft 33. This increases the rotation speed of the two driving wheels 20.

[0034] The second transmission module 32 includes a first chain pulley 321, a second chain pulley 322, and a first chain 323. The first chain 323 is fitted between the first chain pulley 321 and the second chain pulley 322, and functions as a transmission component between the first chain pulley 321 and the second chain pulley 322.

[0035] The first chain pulley 321 is fitted to the first rotating shaft 21, and the second chain pulley 322 is fitted to the second rotating shaft 33. The first chain 323 pulls the first chain pulley 321 and the second chain pulley 322, transmitting power between them. In this case, the second rotating shaft 33 is connected to one end of the first transmission module 31 and one end of the second transmission module 32, and the other end of the first transmission module 31 and the other end of the second transmission module 32 are connected to the first rotating shaft 21, thereby synchronously rotating the two driving wheels 20. The first transmission module 31 is a synchronous belt transmission module, and the second transmission module 32 is a chain transmission module. At this time, the first transmission module 31 acts on the second rotating shaft 33 and the first rotating shaft 21, and the second transmission module 32 acts on the second rotating shaft 33 and the first rotating shaft 21, so that the second rotating shaft 33 connects the two driving wheels 20. The cooperative action of the second rotating shaft 33, the first transmission module 31, and the second transmission module 32 ensures the synchronous rotation of the two driving wheels 20, and effectively utilizes the inertia of the second rotating shaft 33, the first transmission module 31, and the second transmission module 32, thereby improving the rotation speed of the two driving wheels 20.

[0036] The second chain pulley 322 and the second synchronizing pulley 312 are both fitted onto the second rotating shaft 33 and are spaced apart along the axis of the second rotating shaft 33. The pulley diameter of the second chain pulley 322 is smaller than that of the second synchronizing pulley 312. Increasing the pulley diameter of the second synchronizing pulley 312 increases the mass of the second synchronizing pulley 312, thereby increasing the inertial action of the second synchronizing pulley 312 after rotation. As a result, the inertial action force of the second synchronizing pulley 312 is transmitted to the second rotating shaft 33 and further transmitted to the two driving wheels 20 via the second rotating shaft 33, thereby increasing the rotation speed of the two driving wheels 20.

[0037] The power assembly 40 functions as a power component of the power source. The power assembly 40 is connected to the first rotating shaft 21 and drives the first rotating shaft 21 to rotate. At this time, the power assembly 40 outputs power to the first rotating shaft 21, and the first rotating shaft 21 rotates the two driving wheels 20 under power, and also operates the first transmission module 31 and the second transmission module 32. As a result, the inertial acting force of the second synchro pulley 312 increases during the operation process. At this time, the inertial acting force of the second synchro pulley 312 increases as the rotation speed increases.

[0038] Specifically, the power assembly 40 includes a power motor 41 and a third transmission module 42. The power motor 41 is mounted on the mounting seat 10. One end of the third transmission module 42 is connected to one end of the power motor 41, and the other end is connected to the first rotating shaft 21 to drive and rotate the first rotating shaft 21. This causes the first rotating shaft 21 to operate, and the third transmission module 42 transmits the working force of the power motor 41 to the first rotating shaft 21, and then to the first transmission module 31 and the second transmission module 32. In the above description, as a further embodiment, the third transmission module 42 is a chain transmission module.

[0039] Furthermore, the power motor 41 is connected to a solar panel 43 and can be operated under the energy supply from the solar panel 43. In this case, the solar panel 43 can absorb sunlight, and an absorbing surface is provided on the surface of the solar panel 43, which is exposed to the external environment and is irradiated with sunlight. Therefore, the power motor 41 is operated by solar energy, and the third transmission module 42 transmits the working force of the power motor 41 to the first rotating shaft 21, and further to the first transmission module 31 and the second transmission module 32. In the above description, as a further embodiment, the third transmission module 42 is a chain transmission module.

[0040] Second Example Referring to FIG. 4 , a blower 44 is provided on one side of the solar panel 43, and the solar panel 43 and the blower 44 act on the power motor 41. At this time, the power motor 41 is attached to the mounting base 10. One end of the third transmission module 42 is connected to one end of the power motor 41, and the other end is connected to the first rotating shaft 21 to drive and rotate the first rotating shaft 21. This operates the first rotating shaft 21, and in this case, the second synchronizer pulley 312 is connected to the first rotating shaft 21 and rotates the second synchronizer pulley 312. Because the mass of the second synchronizer pulley 312 is relatively large, the inertial action of the second synchronizer pulley 312 after rotation is increased, and the inertial action force of the second synchronizer pulley 312 is transmitted to other components, thereby increasing the rotation speed of the two drive wheels 20.

[0041] Third Example 5, the solar panel 43 acts on the power motor 41, and the power motor 41 is attached to the mounting base 10. One end of the third transmission module 42 is connected to one end of the power motor 41, and the other end is connected to the first rotating shaft 21 to drive and rotate the first rotating shaft 21. This operates the first rotating shaft 21, and in this case, the second synchronizer pulley 312 is connected to the first rotating shaft 21 and rotates the second synchronizer pulley 312. Because the mass of the second synchronizer pulley 312 is relatively large, the inertial action of the second synchronizer pulley 312 after rotation is increased, and the inertial action force of the second synchronizer pulley 312 is transmitted to other components, thereby increasing the rotation speed of the two drive wheels 20.

[0042] Fourth Example 6, the solar panel 43 acts on the power motor 41, and the solar panel 43 is disposed above the power motor 41, which is attached to the mounting base 10. One end of the third transmission module 42 is connected to one end of the power motor 41, and the other end is connected to the first rotating shaft 21 to drive and rotate the first rotating shaft 21. This operates the first rotating shaft 21, and in this case, the second synchronizer pulley 312 is connected to the first rotating shaft 21 and rotates the second synchronizer pulley 312. Because the mass of the second synchronizer pulley 312 is relatively large, the inertial effect of the second synchronizer pulley 312 after rotation is increased, and the inertial force of the second synchronizer pulley 312 is transmitted to other components, thereby increasing the rotation speed of the two drive wheels 20.

[0043] Fifth Example 7, a third transmission module 42 is provided on one side of the power motor 41 to act on the power motor 41, and the power motor 41 is attached to the mounting seat 10. One end of the third transmission module 42 is connected to one end of the power motor 41, and the other end is connected to the first rotating shaft 21 to drive and rotate the first rotating shaft 21. This operates the first rotating shaft 21, and in this case, the second synchronizer pulley 312 is connected to the first rotating shaft 21 to rotate the second synchronizer pulley 312. Because the mass of the second synchronizer pulley 312 is relatively large, the inertial action of the second synchronizer pulley 312 after rotation is increased, and the inertial action force of the second synchronizer pulley 312 is transmitted to other components, thereby increasing the rotation speed of the two drive wheels 20.

[0044] Furthermore, the power machine may be equipped with a time control device. The time control device is electrically connected to the power motor 41 and controls the start or stop of the power motor 41 at regular intervals. In this case, after the power motor 41 has rotated for a preset time, the time control device automatically disconnects the power supply to the power motor 41 for a certain period of time, stopping the operation of the power motor 41. As a result, the second synchro pulley 312 rotates for a certain period of time due to inertia. After the rotation speed decreases or stops, the time control device automatically reconnects the power motor 41 and rotates the power motor 41 by supplying power. In this way, there is no need to manually disconnect and connect the power supply to the power motor 41.

[0045] Compared with the prior art, the beneficial effects of the present invention are as follows: The two driving wheels 20 rotate relative to the mounting seat 10. A first rotating shaft 21 is connected to each of the two driving wheels 20, and each of the first rotating shafts 21 is rotatably mounted on the mounting seat 10. The traction assembly 30 includes a first transmission module 31, a second transmission module 32, and a second rotating shaft 33. The second rotating shaft 33 is connected to one end of the first transmission module 31 and one end of the second transmission module 32, and the other end of the first transmission module 31 and the other end of the second transmission module 32 are connected to the respective first rotating shafts 21, thereby synchronously rotating the two driving wheels 20. The first transmission module 31 is a synchronous belt transmission module, and the second transmission module 32 is a chain transmission module. In this case, the first transmission module 31 acts on the second rotating shaft 33 and the first rotating shaft 21, and the second transmission module 32 acts on the second rotating shaft 33 and the first rotating shaft 21, so that the second rotating shaft 33 connects the two driving wheels 20, and the synchronous rotation of the two driving wheels 20 is ensured through the cooperative action of the second rotating shaft 33, the first transmission module 31, and the second transmission module 32. Furthermore, the inertia of the second rotating shaft 33, the first transmission module 31, and the second transmission module 32 is effectively utilized, thereby increasing the rotation speed of the two driving wheels 20.
