While current fixed-wing propeller aircraft are equipped with some basic safety devices, they often lack effective auxiliary power means to maintain stable flight and safe landing when dealing with sudden power problems. Furthermore, existing safety devices are inadequate in energy recovery and reuse, failing to fully utilize the energy generated during flight and resulting in energy waste. Therefore, there is an urgent need for an electrically powered auxiliary safety device that can solve these problems to improve the safety and energy efficiency of fixed-wing propeller aircraft.

[0022] like Figure 1-5 As shown: This embodiment provides an electrically assisted safety device for a fixed-wing aircraft, including a cabin panel 100. An engine 101 is mounted on the top of the cabin panel 100. A first drive shaft 102 is mounted on the output end of the engine 101. A first retainer 103 is rotatably connected to the outer side of the first drive shaft 102. The bottom end of the first retainer 103 is fixedly connected to the top of the cabin panel 100.

An auxiliary mechanism 112 for driving the third drive shaft 113 to rotate is installed on one end face of the third retainer 114 to realize the electric drive function after the engine 101 fails.
[0024] like Figure 4As shown, the translation mechanism 116 includes a connecting sleeve 11601, the inner side of the connecting sleeve 11601 and the outer side of the groove 10601 are rotatably connected, a connecting plate 11602 is installed on one side of the connecting sleeve 11601, a first fixed seat 11605 is installed on one side of the first retainer 103, an electric telescopic rod 11606 is installed at one end of the first fixed seat 11605, a push plate 11607 is installed at the output end of the electric telescopic rod 11606, and one end of the push plate 11607 is in contact with one end face of the connecting plate 11602.
[0025] A push plate 11607 is installed at the output end of the electric telescopic rod 11606. When the engine 101 fails, the electric telescopic rod 11606 drives the push plate 11607 to move, thereby pushing the connecting plate 11602, causing the connecting sleeve 11601 to drive the connecting seat 106 to move, thereby separating the toothed hub 104 and the toothed disc 105, which facilitates the intervention of the auxiliary mechanism 112.

[0031] The arrangement of motor 11201, drive gear 11202 and driven gear 11203 provides reliable electric auxiliary power for the aircraft. When engine 101 fails, motor 11201 starts and drives the third drive shaft 113 to rotate through the meshing transmission of drive gear 11202 and driven gear 11203, thereby driving propeller 115 to rotate, enabling the aircraft to maintain basic flight capability.

[0035] A controller 120 is installed at the top of the nacelle panel 100 to make the equipment controllable and increase the ease of use of the product;
[0036] Working principle: The toothed hub 104 and toothed disc 105 enable the switching of the output power of the engine 101 between connection and disconnection. A square sleeve 111 is slidably connected to the outer side of the square rod 110, facilitating power transmission after the second drive shaft 109 moves. A translation mechanism 116 for moving the connecting seat 106 is rotatably connected to the outer side of the groove 10601, allowing the connecting seat 106 to move and thus quickly disconnecting the second drive shaft 109 from the engine 101.

The arrangement of motor 11201, drive gear 11202 and driven gear 11203 provides reliable electric auxiliary power to the aircraft. When the engine 101 fails, motor 11201 starts and drives the third drive shaft through the meshing transmission of drive gear 11202 and driven gear 11203. The rotation of engine 113 drives propeller 115 to rotate, enabling the aircraft to maintain basic flight capability. When engine 101 is running, it can drive motor 11201 to perform reverse charging. Through the configuration of rectifier 117, charging module 118 and lithium battery 119, the AC power generated by motor 11201 during passive operation can be converted into DC power, thereby charging lithium battery 119 through charging module 118. The controller 120 installed on the top of the cabin panel 100 enables the equipment to be controlled, increasing the ease of use of the product.
