Description

Technical Field

[0001] The present invention relates to the field of ejection seat equipment, and more particularly to a human body protection device for an ejection seat. Background Art

[0002] An ejection seat is a safety device used to quickly eject a pilot from an aircraft in an emergency. It usually consists of a seat structure, an ejection power system, a stabilization and deceleration system, a program control system, and a life parachute. The ejection seat is designed to ensure the pilot's safe ejection and survival probability under various flight conditions, including high speed, low altitude, and unfavorable postures. During the ejection process, the protective equipment will provide certain protection to the pilot to improve the pilot's survival efficiency.

[0003] At present, when the existing ejection seat human protection equipment is in use, the launcher inside the ejection seat will generate huge instantaneous acceleration, and the huge acceleration will push upward from the bottom of the seat. Therefore, when the pilot uses the ejection seat to escape, the buttocks will first be pushed upward, while the pilot's upper body has not yet been pushed upward, which will cause certain damage to the pilot's spine. In addition, when the pilot flies out of the plane, there will be huge strong winds blowing on the pilot's body. Although the pilot will wear protective clothing, his neck lacks protection devices, which will cause damage to the neck, and in severe cases, it may be life-threatening. Summary of the Invention

[0046] like Figures 1 to 4 As shown, an embodiment of the present invention provides a human body protection device for an ejection seat, comprising an ejection seat body 1 , and a spine protection mechanism 2 is provided on the right side of the ejection seat body 1 .

[0047] The spine protection mechanism 2 includes a rectangular box 204, two rectangular grooves 203 are provided on the left side of the rectangular box 204, and two sliding grooves 202 are provided on the outer surface of the ejection seat body 1. The interior of each sliding groove 202 and the interior of the rectangular groove 203 are both slidably connected to a lifting plate 201. The inner wall of the rectangular box 204 is fixedly connected to a fixed plate 206. The inner wall of the fixed plate 206 is rotatably connected to two first rotating shafts 207. The inner wall of the rectangular box 204 is rotatably connected to two second rotating shafts 210. The bottom end of each first rotating shaft 207 and the top end of the second rotating shaft 210 are both fixedly connected to a threaded shaft 208. The outer surface of each threaded shaft 208 is threadedly connected to a rectangular plate 209. A first power output assembly is provided below the fixed plate 206, and a neck protection mechanism 3 is provided above the ejection seat body 1.

[0048] like Figure 1As shown, the left side of the rectangular box 204 is fixedly connected to the right side of the ejection seat body 1, and the left side of each rectangular plate 209 is fixedly connected to the right side of the lifting plate 201. Since the rectangular box 204 is fixed to the right side of the ejection seat body 1, the ejection seat body 1 will also drive the rectangular box 204 to move upward synchronously during the upward movement.

[0049] like Figure 4 As shown, the first power output assembly includes a fixed frame 205 fixedly connected to the inner wall of the rectangular box 204, the inner wall of the fixed frame 205 is fixedly connected to the first stepper motor 211, the output end of the first stepper motor 211 is fixedly connected to the rotating shaft 213, the outer surface of the rotating shaft 213 is rotatably connected to the inner wall of the fixed frame 205, the outer surface of the rotating shaft 213 is fixedly connected to two first gears 212, the outer surface of each first rotating shaft 207 is fixedly connected to the second gear 215, and the outer surface of each first gear 212 and the outer surface of the second gear 215 are fixedly connected. They are meshed with a first toothed belt 214. By providing a first stepper motor 211, the first stepper motor 211 will drive the rotating shaft 213 fixed at its output end and the first gear 212 fixed on the outer surface of the rotating shaft 213 to rotate when running, and the outer surface of the first gear 212 is meshed with a first toothed belt 214, and the first toothed belt 214 is in meshing relationship with the second gear 215. Therefore, the power generated by the first stepper motor 211 when running will be transmitted to the two first rotating shafts 207, thereby driving the two first rotating shafts 207 to rotate, realizing force transmission.

[0050] During use, when the pilot wants to use the ejection seat body 1, he needs to pull the drawstring above the ejection seat body 1. When the drawstring is triggered, the aircraft will release the canopy, fix the pilot on the seat and start the ejection rocket. Therefore, the ejection seat body will not eject immediately after being triggered, but will eject within a few seconds. Therefore, when the ejection seat body 1 is triggered and started, the first stepper motor 211 will be controlled to operate through an external control device. The first stepper motor 211 is a motor that converts an electrical pulse signal into a mechanical angular displacement. It does not require a feedback system to achieve precise position control. When the first stepper motor 211 receives a pulse signal, its rotor will rotate a fixed angle, called the step angle. By controlling the number and frequency of pulses, the rotation angle and speed of the first stepper motor 211 can be controlled. When the first stepper motor 211 is running, it will drive the rotating shaft 213 fixed at its output end and the rotating shaft 213 fixed on the outer surface. The first gear 212 rotates, and the outer surface of the first gear 212 is meshed with a first toothed belt 214, and the first toothed belt 214 is in meshing relationship with the second gear 215. Therefore, the power generated by the first stepper motor 211 when it is running will be transmitted to the two first rotating shafts 207. After receiving the rotational power, the first rotating shaft 207 will drive the threaded shaft 208 to rotate. The threaded plate connection relationship between the rectangular plate 209 and the threaded shaft 208 can be used to drive the rectangular plate 209 to move upward, thereby driving the lifting plate 201 to move upward until the lifting plate 201 moves under the pilot's arm to provide support for the pilot's arm. When the rocket launcher inside the ejection seat body 1 is started, the thrust generated by the rocket launcher body 1 will not only act on the pilot's buttocks, but the pilot's two arms will also be subjected to upward thrust, thereby greatly reducing the impact force on the spine, thereby achieving the purpose of protecting the pilot's spine.

[0051] like Figure 1 、 Figures 5 to 9 As shown, the neck protection mechanism 3 includes a windshield 314. A first rotation slot 301 is defined on the upper surface of the rectangular box 204. Two second rotation slots 312 are defined on the upper surface of the ejection seat body 1. A gear ring 309 is fixedly connected to the bottom surface of the windshield 314. A transmission shaft 303 is rotatably connected to the inner wall of the fixed plate 206. A transmission gear 302 is fixedly connected to the outer surface of the transmission shaft 303. An inflation assembly is provided on the outer side of the windshield 314, and a second power output assembly is provided below the windshield 314.

[0052] like Figure 2 、 Figure 6 and Figure 7As shown, the interiors of the two second rotating grooves 312 and the interior of the first rotating groove 301 are both slidably connected to the outer surface of the wind shield 314, and the outer surface of the transmission gear 302 is meshed with the outer surface of the gear ring 309. Since the wind shield 314 slides inside the first rotating groove 301 and the second rotating groove 312, under the joint action of the first rotating groove 301 and the second rotating groove 312, the wind shield 314 will always be supported and will not fall off.

[0053] like Figure 8 and Figure 9 As shown, the inflation assembly includes a reaction box 311 fixedly connected to the outer surface of the windshield 314, the inner wall of the reaction box 311 is fixedly connected to a partition 317, and the upper surface of the partition 317 is fixedly connected to an igniter 315. The igniter 315 is a device for generating electric sparks, which can ignite combustible gas or mixed fuel. In different applications, the design and working principle of the igniter 315 may be different. The working mechanism of the igniter 315 is usually based on the electromagnetic induction phenomenon. When the primary circuit of the ignition coil is energized, high-voltage electrical energy is generated in the secondary coil. This high-voltage electrical energy is then transmitted to the distributor and distributed to each spark plug according to the ignition sequence of the engine. In the electrode gap of the spark plug, the high-voltage electrical energy generates sparks. The output end of the igniter 315 is fixed. An ignition head 316 is connected, and the bottom end of the ignition head 316 extends to the bottom of the partition 317. The outer surface of the ignition head 316 is fixedly connected to the inner wall of the partition 317. The interior of the reaction box 311 is clamped with a disassembly plate 310. The interior of the windshield 314 is connected to the interior of the reaction box 311. The inner wall of the windshield 314 is fixedly connected with an inflatable airbag 313. The interior of the inflatable airbag 313 is connected to the interior of the windshield 314. By providing an inflatable component, the inflatable airbag 313 can be inflated by the inflatable component to expand the inflatable airbag 313. Here, the inflatable airbag 313 is made of nylon cloth, which has high strength, wear resistance and tear resistance, and is suitable for making high-pressure airbags, thereby avoiding the problem of the pilot's neck being hit during flight.

[0054] like Figure 9 As shown, the inner wall of the reaction box 311 is rotatably connected to a short shaft 8, and the right end of the short shaft 8 is fixedly connected to a baffle 9. The left side of the baffle 9 is in contact with the right side of the reaction box 311 and the right side of the disassembly plate 310 respectively. The short shaft 8 can provide supporting force for the baffle 9, and the baffle 9 can provide a limit for the disassembly plate 310, while making it easy to disassemble the disassembly plate 310.

[0055] like Figure 5 and Figure 6As shown, the second power output assembly includes a second stepper motor 304 fixedly connected to the inner wall of the fixed frame 205, the output end of the second stepper motor 304 is fixedly connected to the output shaft 305, the outer surface of the output shaft 305 is rotatably connected to the inner wall of the fixed plate 206, the outer surface of the output shaft 305 is fixedly connected to the first circular gear 306, the outer surface of the transmission shaft 303 is fixedly connected to the second circular gear 308, the outer surface of the second circular gear 308 and the outer surface of the first circular gear 306 are jointly meshed with a second toothed belt 307, by providing the second stepper motor 304, the operation of the second stepper motor 304 will also drive the output shaft 305 fixed at the output end of the second stepper motor 304 and the first circular gear 306 to rotate, and the meshing relationship between the first circular gear 306, the second toothed belt 307 and the second circular gear 308 is utilized to synchronously transmit the power generated by the second stepper motor 304 during operation to the transmission shaft 303, driving the transmission gear 302 fixed on the outer surface of the transmission shaft 303 to rotate, thereby achieving the purpose of transmission.

[0056] like Figure 1 As shown, a protective pad 5 is provided inside the ejection seat body 1, and the outer surface of the protective pad 5 is in contact with the inner wall of the ejection seat body 1. By providing the protective pad 5, the protective pad 5 can provide protection for the pilot's back. In fact, during ejection, the back will not be squeezed and deformed due to strong wind force.

[0057] like Figure 7 As shown, a support block 6 is fixedly connected to the upper surface of the ejection seat body 1, and a headrest 7 is fixedly connected to the upper surface of the support block 6. A head protection mechanism 4 is provided inside the headrest 7. By providing the support block 6, the support block 6 can provide support to the headrest 7, and the headrest 7 can provide support force to the pilot's head.

[0058] When the first stepper motor 211 is running, the second stepper motor 304 will also rotate synchronously. When the second stepper motor 304 rotates, it will also drive the output shaft 305 fixed at the output end of the second stepper motor 304 and the first circular gear 306 to rotate. By utilizing the meshing relationship between the first circular gear 306, the second toothed belt 307 and the second circular gear 308, the power generated by the second stepper motor 304 when running can be synchronously transmitted to the transmission shaft 303, thereby driving the transmission gear 302 fixed on the outer surface of the transmission shaft 303 to rotate, and then utilizing the meshing relationship between the transmission gear 302 and the gear ring 309, It can drive the gear ring 309 and the windshield 314 fixed on the upper surface of the gear ring 309 to rotate until the windshield 314 completely provides shielding for the pilot's neck after rotating half a circle. When the windshield 314 is in place, the igniter 315 is controlled by an external control device to operate, and the sodium azide powder placed inside the reaction box 311 is heated by the igniter 315 to generate a large amount of gas. These gases first enter the interior of the windshield 314, and then enter the interior of the inflatable airbag 313 through the windshield 314. Therefore, there is no need to worry about the inflatable airbag 313 being suddenly filled with gas and rapidly expanding to cause damage to the pilot's neck.

[0059] like Figure 1 and Figure 10 As shown, the head protection mechanism 4 includes a protective plate 405, the outer surface of the protective plate 405 is slidably connected to the inside of the headrest 7, the outer surface of the protective plate 405 is fixedly connected to two flexible pads 407, the front of the protective plate 405 is fixedly connected to a return spring 406, the inner wall of the protective plate 405 is rotatably connected to a rotating shaft 402, the outer surface of the rotating shaft 402 is respectively fixedly connected to a limit block 401 and a transmission block 404, and the upper surface of the windshield 314 is fixedly connected to a push block 403.

[0060] When the windshield 314 rotates, the pushing block 403 fixed on the upper surface of the windshield 314 will also rotate accordingly. When the pushing block 403 contacts the transmission block 404, the pushing block 403 will push the transmission block 404 to rotate. Therefore, the rotation of the transmission block 404 will also drive the limit block 401 to rotate. When the limit block 401 rotates to the notch opened on the right side of the headrest 7, the limit block 401 will only be pushed by the return spring 406. Therefore, it can push the protective plate 405 to move out of the inside of the headrest 7, which can provide limits on both sides of the pilot's head and ensure that the pilot's head will not shake during the ejection process.

[0061] The working process of the technical solution provided by the present invention is as follows:

[0062] When in use, it is necessary to pull the drawstring above the ejection seat body 1. When the drawstring is triggered, the first stepper motor 211 will be controlled by an external control device to operate, which can drive the lifting plate 201 to move upward until the lifting plate 201 moves under the pilot's arm, providing support for the pilot's arm, thereby achieving the purpose of protecting the pilot's spine.

[0063] When the first stepper motor 211 is running, the second stepper motor 304 will also rotate synchronously. After a series of force transmission and the meshing relationship between the transmission gear 302 and the gear ring 309, the gear ring 309 and the windshield 314 fixed on the upper surface of the gear ring 309 can be driven to rotate until the windshield 314 rotates half a circle and completely provides protection for the pilot's neck. When the windshield 314 is in place, the igniter 315 is controlled by an external control device to operate, so that the interior of the inflatable airbag 313 is filled with gas.

[0064] And when the windshield 314 rotates, the pushing block 403 fixed on the upper surface of the windshield 314 will also rotate accordingly. When the pushing block 403 contacts the transmission block 404, the pushing block 403 will push the transmission block 404 to rotate. Therefore, the rotation of the transmission block 404 will also drive the limit block 401 to rotate. When the limit block 401 rotates to the notch opened on the right side of the headrest 7, the limit block 401 will only be pushed by the return spring 406. Therefore, it can push the protective plate 405 to move out of the inside of the headrest 7, which can provide limits on both sides of the pilot's head and ensure that the pilot's head will not shake during the ejection process.

[0065] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
