[0049] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0050] like Figures 1 to 5 As shown, this embodiment provides a power system that can switch between an electric drive state and a pneumatic drive state, including an electric module 1 and a pneumatic module 2, as well as a gear module 6 for outputting power and a non-electrically driven switching power module 4 for switching the power output path, wherein:

[0051] The gear module 6 includes an electric gear 61 driven by the electric module 1 and a pneumatic gear 62 driven by the pneumatic module 2, as well as a driven gear 63 for outputting power. Both the electric gear 61 and the pneumatic gear 62 are engaged with the driven gear 63.

[0052] It also includes an electric transmission assembly 7 and a pneumatic transmission assembly 8, each of which has a disengaged state and an engaged state and the states are opposite, and a clutch assembly 5 driven by a switching power module 4;

[0053] The clutch assembly 5 is used to synchronously switch the state of the electric transmission assembly 7 and the state of the pneumatic transmission assembly 8.

[0054] The power system disclosed in this embodiment has both an electric module 1 and a pneumatic module 2, and by setting up a switching power module 4, and the mutual cooperation of the clutch assembly 5, the electric transmission assembly 7 and the pneumatic transmission assembly 8, the present application can use the power of the driven gear 63 of the driving gear module 6 to rotate from the electric module 1 under conventional conditions, thereby realizing an electric drive state. However, when used in a more complex high-voltage, strong electromagnetic and atomic radiation interference environment, thereby causing circuit signal problems, the present application can directly switch the power source for driving the driven gear 63 to the pneumatic module 2 by switching the power module 4, and the mutual cooperation of the clutch assembly 5, the electric transmission assembly 7 and the pneumatic transmission assembly 8, thereby realizing a pneumatic drive state and avoiding power output problems caused by a complex external environment.

[0055] In this embodiment, the clutch assembly 5 includes an electric paddle 51 and a pneumatic paddle 52 , as well as a return spring 53 and a guide shaft 54 ;

[0056] The electric paddle 51, the pneumatic paddle 52, and the return spring 53 are mounted on the guide shaft 54 in sequence from bottom to top vertically. The end of the electric paddle 51 away from the guide shaft 54 is mounted on the electric transmission assembly 7, and the end of the pneumatic paddle 52 away from the guide shaft 54 is mounted on the pneumatic transmission assembly 8.

[0057] The power output end of the switching power module 4 is connected to the bottom of the guide shaft 54 .

[0058] In this embodiment, when it is necessary to switch to the power output mode of the pneumatic module 2, the switching power module 4 is turned on, so that its power output end drives the electric paddle 51 and the pneumatic paddle 52 at the same time, thereby causing the electric paddle 51 and the pneumatic paddle 52 to move upward along the axial direction of the guide shaft 54 at the same time, so that the electric paddle 51 changes the meshing state of the electric transmission component 7 into a disengaged state, so that the power output path between the electric module 1 and the electric gear 61 is cut off, and at the same time, the pneumatic paddle 52 changes the disengaged state of the pneumatic transmission component 8 into a meshing state, so that the power output path between the pneumatic module 2 and the pneumatic gear 62 is When the clutch assembly 5 is engaged, the electric paddle 51 and the pneumatic paddle 52 are both moved and reset in the direction of the guide shaft 54, so that the disengaged state of the electric transmission assembly 7 is switched to the engaged state, and at the same time, the engaged state of the pneumatic transmission assembly 8 is switched to the disengaged state, so that the power output of the entire power system is completed by the electric module 1.

[0059] In this embodiment, both ends of the electric paddle 51 and the pneumatic paddle 52 are provided with a ring structure, and a connecting rod structure is provided between the two ring structures. The electric paddle 51 is respectively mounted on the guide shaft 54 and the electric transmission assembly 7 through the ring structures at both ends, and the pneumatic paddle 52 is respectively mounted on the guide shaft 54 and the pneumatic transmission assembly 8 through the ring structures at both ends.

[0060] In this embodiment, the electric transmission assembly 7 includes a coaxially arranged electric gear shaft 71 and a transmission gear shaft 72.

[0064] In this embodiment, the two power output ends of the clutch assembly 5 are the collar structures of the electric paddle 51 and the pneumatic paddle 52 away from the guide shaft 54 .

[0065] In this embodiment, when the electric module 1 outputs power, the electric gear shaft 71 and the transmission gear shaft 72 engage with each other through the end face teeth set close to one end, so that the electric transmission assembly 7 is in an engaged state. In this embodiment, when the pneumatic module 2 outputs power, the end face teeth of the electric gear shaft 71 and the end face teeth of the transmission gear shaft 72 are separated from each other, so that the electric transmission assembly 7 is in a separated state, and the power of the electric module 1 cannot be transmitted to the electric gear 61.

[0066] In this embodiment, a mounting groove is provided at the bottom of the electric gear 61, and the top of the transmission gear shaft 72 is installed in the mounting groove;

[0069] By providing a mounting groove at the bottom of the electric gear 61, the transmission gear shaft 72 can be directly installed in the mounting groove, thereby driving the electric gear 61 to rotate when the electric transmission assembly 7 is in an engaged state. In this embodiment, the portion of the transmission gear shaft 72 located above its annular convex structure is a hexagonal prism structure, and the shape of the mounting groove is also a hexagonal prism groove that matches its shape. Technicians can also set the shape of the mounting groove and the portion of the transmission gear shaft 72 located above its annular convex structure to other shapes such as triangular prism and quadrangular prism as needed. The details are not repeated here.

The first bearing 73 and the second bearing 74 in this embodiment are both existing components. At the same time, the influence of the electric paddle 51 on the transmission gear shaft 72 is avoided as much as possible. At the same time, an electric top pressure spring 75 is also provided in this embodiment, so that when the power system of this embodiment changes from the power output mode of the pneumatic module 2 to the power output mode of the electric module 1, the electric top pressure spring 75 can drive the transmission gear shaft 72 to approach the electric gear shaft 71, so that the end face teeth of the two are engaged with each other, thereby making the electric transmission assembly 7 be in and maintain an engaged state.

[0071] In this embodiment, the pneumatic transmission assembly 8 includes a pneumatic gear shaft 81 and a pneumatic pressure spring 82.

When the power system of this embodiment is in the power output mode of the electric module 1, the end teeth of the pneumatic gear shaft 81 and the end teeth of the pneumatic gear 62 can be separated from each other through the pneumatic pressure spring 82, thereby switching the pneumatic transmission module from the meshing state to the disengaged state.

[0077] In this embodiment, the pneumatic gear shaft 81 is provided with an annular convex structure, and the power output end of the clutch assembly 5 is sleeved on the pneumatic gear shaft 81 and located below the annular convex structure;

[0078] The pneumatic transmission assembly 8 further includes a third bearing 83 sleeved on the pneumatic gear shaft 81 . The third bearing 83 is located between the annular convex structure and the power output end of the clutch assembly 5 .
