DETAILED DESCRIPTION

[0036] The present invention will be described in further detail below with reference to the accompanying drawings.

[0037] An ejection seat simulator, such as Figure 1 、 Figure 2 and Figure 4 Shown, including:

[0038] a seat body 31 comprising a seat back panel 311 and a seat bottom panel 312 at the bottom end of the seat back panel 311 , with a seat cushion being laid on the seat bottom panel 312 ; and

[0039] A detachment mechanism 4 is provided in contact with the seat back panel 311, the detachment mechanism 4 comprising a detachment plate 41 on which a safety belt is mounted, the detachment plate 41 being detachably connected to the seat body 31 via at least two locking assemblies 42;

[0040] The seat bottom plate 312 is equipped with an ejection activation mechanism for controlling the locking assembly 42 to disengage the detachment mechanism 4 from the seat body 31. Specifically, the ejection activation mechanism includes a first proximity switch. By pulling the ejection ring 7 of the ejection activation mechanism, the first proximity switch receives a signal that is fed back to the control system. The control system then controls the electromagnet 423 of the locking assembly 42 to attract the locking push rod 424, thereby pulling the locking push rod 424 out of the locking hole of the detachment plate 41. (The ejection activation mechanism can adopt an existing structure and will not be described in detail in this disclosure.)

[0041] According to a specific embodiment of the present invention, an ejection seat simulator 3 includes a seat body 31 and a release mechanism 4. The bottom end of a seat back 311 is connected to one end of a seat bottom 312. A left side guard is provided on the left side of the seat body 31, and a right side guard is provided on the right side of the seat body 31. The left side guard is fixed to a left armrest, and the right side guard is fixed to a right armrest. The left and right side guards are symmetrically structured, each with an L-shaped structure. They are aligned with the sides of the seat back 311 and the seat bottom 312 and are secured to the sides of the seat back 311 and the seat bottom 312 by fasteners. During ejection simulation training, a trainee sits on the seat cushion of the seat bottom 312, with their back secured to the release plate 41 by a safety belt (not shown). The safety belt can be arranged in a cross pattern, with the ends of the belts connected at the four corners of the release plate 41 to ensure the trainee's safety.

[0042] In this embodiment, the detachment plate 41 of the detachment mechanism 4 is detachably connected to the seat body 31 via at least two locking assemblies 42. Specifically, the number of locking assemblies 42 can be set to four, which are respectively installed at the four corners of the rectangular seat back panel 311. The life-saving simulation training equipment of the present invention includes ejection and parachute landing processes. During the ejection process, the detachment mechanism 4 and the seat body 31 are integrally arranged. Until the parachute landing stage, the detachment mechanism 4 is detached from the seat body 31, and the trainee is also hoisted into the parachute landing state along with the detachment plate 41 under the action of the sling. During the ejection simulation training to the parachute landing process, the trainee needs to operate the ejection start mechanism installed on the seat bottom panel 312 to control the locking assembly 42 so that the detachment plate 41 is detached from the seat body 31.

[0043] The present invention solves the technical problem that the existing ejection seat can only rotate on the base or can only eject a certain distance, but cannot separate the trainee from the seat body 31. The ejection seat of the present invention can separate the trainee from the seat body 31, thereby preparing for the subsequent parachute process.

[0044] Furthermore, if Figure 3 and Figure 5As shown, in order to ensure the reliability of the connection between the detachment plate 41 and the seat back plate 311, there are four locking components 42, and each locking component 42 includes a locking mounting seat 421, a locking spring 422, an electromagnet 423 and a locking push rod 424. The locking mounting seat 421 is fixed on the seat back plate 311, and the electromagnet 423 is fixed on one side of the locking mounting seat 421. The locking push rod 424 is provided on one side of the electromagnet 423. The locking push rod 424 passes through the hole opened in the locking mounting seat 421, and the locking spring 422 is sleeved on the outside of the locking push rod 424. The locking mounting seat 421 is fixed with a spring limiting plate 425, and one end of the locking spring 422 abuts against one side of the spring limiting plate 425, so that the end of the locking push rod 424 away from the electromagnet 423 under the action of the locking spring 422 can extend into the locking hole opened in the detachment plate 41.

[0045] According to a specific embodiment provided by the present invention, this embodiment provides a specific structure of a locking assembly 42, and the locking mounting seat 421 as a whole can be a long plate-type structure, which is fixed to the back of the seat back plate 311 by fasteners. An electromagnet 423 is fixed on one side of the locking mounting seat 421, and a locking push rod 424 is provided on one side of the electromagnet 423. After the electromagnet 423 is energized, it adsorbs the locking push rod 424 to overcome the force of the locking spring 422 and moves. The locking mounting seat 421 extends vertically away from the end of the electromagnet 423 to form a switch mounting plate 426, and the locking push rod 424 passes through the hole opened in the switch mounting plate 426. The switch mounting plate 426 can limit the moving direction of the locking push rod 424, and the moving direction of the locking push rod 424 is parallel to the length direction of the locking mounting seat 421.

[0046] The spring limit plate 425 of this embodiment is located between the locking spring 422 and the electromagnet 423. One end of the locking spring 422 abuts against one side of the spring limit plate 425, and the other end abuts against the plate body on the locking push rod 424. The specific structure of the plate body on the locking push rod 424 is not limited here, and it is sufficient to provide an installation position for the locking spring 422. The locking ears 411 are provided on the disengagement plate 41 corresponding to the four locking components 42. The locking ears 411 have a locking hole. Under the push of the locking spring 422, the end of the locking push rod 424 is extended into the locking hole. The electromagnet 423 is energized to adsorb the end of the locking push rod 424, so that the end of the locking push rod 424 extends from the locking hole opened in the disengagement plate 41. At this time, the disengagement mechanism 4 can be detached from the seat body 31.

[0047] Furthermore, the locking assembly 42 also includes a status detection unit, which includes a first proximity switch 427. The locking mounting base 421 has a switch mounting plate 426, on which the first proximity switch 427 is mounted. The locking push rod 424 has a contact plate 428, which can also be used to abut the locking spring 422. The contact plate 428 is arranged parallel to the switch mounting plate 426, and the end of the locking spring 422 abuts the contact plate 428, so that the contact plate 428 can contact the first proximity switch 427 under the action of the locking spring 422. The contact plate 428 provides a mounting position for the locking spring 422 and also serves as a structure for triggering the first proximity switch 427.

[0048] According to a specific embodiment provided by the present invention, in order to detect whether the end of the locking push rod 424 extends into the locking hole, that is, whether the disengagement plate 41 is fixed to the seat back plate 311, the locking assembly 42 of this embodiment also includes a status detection unit, and the status detection unit includes a first proximity switch 427.

[0049] A proximity switch is a position switch that operates without direct mechanical contact with moving parts. When an object (such as a trainer's body or a contact plate) approaches the switch's sensing surface within the operating distance, the switch actuates without mechanical contact or pressure, thereby driving a DC appliance or providing control commands to a computer (PLC). Also known as a contactless proximity switch, this type of switch is an ideal electronic switching sensor. When a metal detector approaches the switch's sensing area, the switch quickly issues electrical commands without contact, pressure, or sparks, accurately reflecting the position and travel of the moving mechanism. Even for general travel control, it offers advantages such as high positioning accuracy, long service life, easy installation and adjustment, and robustness in harsh environments.

[0050] Both the first proximity switch and the second proximity switch can be capacitive proximity switches. The sensing head of the capacitive proximity switch is installed on the switch mounting plate. The sensing head can be a circular or square flat electrode, forming a distributed capacitance with the ground wire of the oscillation circuit. A contact plate 428 is fixed around the locking push rod 424. The contact plate 428 can be an electrical conductor. When the contact plate 428 approaches the sensing head, the capacitance increases and the oscillator stops oscillating, and an electrical signal is output through the shaping amplifier.

[0051] Furthermore, if Figure 6 and Figure 8 As shown, the disengagement mechanism 4 further includes a padlock assembly 43 mounted on the disengagement plate 41 , and there are two padlock assemblies 43 , each of which includes a padlock housing 431 , a padlock spring 432 and a spring pin 433 ;

[0052] Among them, the padlock shell 431 is a hollow structure, the padlock shell 431 is fixed to the upper part of the disengagement plate 41, and the end of the padlock shell 431 away from the disengagement plate 41 is an open structure. One side of the padlock shell 431 has a cylindrical connecting opening, and the cylindrical connecting opening is located on the outside of the padlock shell 431. The spring pin 433 passes through the padlock spring 432, and the spring pin 433 extends into the padlock shell 431 from the connecting opening. The connecting opening is fixed with a padlock end cover 434, and one end of the padlock spring 432 abuts against the padlock end cover 434, and under the action of the padlock spring 432, the spring pin 433 can pass through to the other side of the padlock shell 431, and the padlock spring 432 is located at one end of the padlock end cover 434 and is provided with a padlock pull ring 435.

[0053] According to a specific embodiment provided by the present invention, a padlock assembly 43 is installed on the upper part of the detachment plate 41, located on both sides of the detachment plate 41. The padlock assembly 43 is used to connect the detachment plate 41 and the parachute rope of the parachute platform 1, so that the detachment mechanism 4 of the ejection seat can continue the parachute process under the pull of the parachute rope.

[0054] The bottom of the padlock shell 431 is fixed to the disengagement plate 41 by fasteners. The padlock shell 431 is a hollow structure with an opening facing upward. The spring pin 433 is a cylindrical structure with different diameters. The end of the spring pin 433 away from the padlock end cover 434 is the large end. The padlock is a plate-shaped structure with a padlock hole (the padlock plate is not visible in the figure). After the padlock plate is extended into the padlock shell 431 from the opening, the large end of the spring pin 433 passes through the padlock hole, and the padlock pull ring 435 passes through the padlock end cover 434 and is fixedly connected to the spring pin 433. In this way, the trainee can pull the padlock pull ring 435 to disengage the spring pin 433 from the padlock hole, so that the padlock plate is disengaged from the disengagement mechanism 4 (usually, the parachute rope and the disengagement mechanism 4 are in a fixed connection state).

[0055] Furthermore, the padlock assembly 43 also includes a booster component 44 installed in the padlock shell 431, and the booster component 44 is arranged below the spring pin 433. The booster component 44 is used to push the padlock plate out of the padlock shell 431 when the padlock plate is taken out. At the same time, the booster component 44 can abut the bottom wall of the padlock hole of the padlock plate against the lower part of the spring pin 433. In this way, when the ejection process is completed, the parachute rope pulls the disengagement mechanism 4 and the trainee to move together, which can avoid the gap between the padlock plate and the spring pin 433, which will cause the disengagement plate 41 to shake and the trainee to feel frustrated.

[0056] Specifically, the boost component 44 includes a boost rod 441, a boost spring 442 and a boost block 443. The boost rod 441 can move in the padlock shell 431. The boost rod 441 passes through the boost spring 442. One end of the boost rod 441 is fixed to the boost block 443. Under the action of the boost spring 442, the boost block 443 has a tendency to move toward the spring pin 433.

[0057] According to a specific embodiment provided by the present invention, the booster rod 441 is arranged along the height direction of the padlock shell 431, facing the opening direction, and the booster rod 441 moves in the vertical direction under the restriction of the padlock shell 431. The booster block 443 is an arc-shaped block structure, and the curvature matches the curvature of the outside of the padlock plate. Under the action of the booster spring 442, the booster block 443 at the end of the booster rod 441 abuts against the outer wall of the padlock spring 432. When the padlock plate is inserted into the padlock shell 431, the end of the padlock plate presses the booster block 443 to overcome the resistance of the booster spring 442, thereby locking the padlock plate and the spring pin 433.

[0058] Furthermore, the disengagement mechanism 4 is equipped with a back sensor assembly 45. Specifically, there are two back sensor assemblies 45, each comprising a second proximity switch and a pressing cap 451 connected to the second proximity switch. The pressing cap 451 engages with the trainee's back. Specifically, a spring passes through the pressing cap 451, which tends to move it away from the disengagement plate 41. When the trainee's body contacts the pressing cap 451, the pressing cap 451 is pressed into the disengagement plate 41, engaging the second proximity switch.

[0059] The back sensor assembly 45 is used to detect whether the trainee is wearing a safety belt and whether the body is in a straight state. That is, if the trainee is wearing a safety belt, the back will press the pressing cap 451 of the back sensor assembly 45, causing the pressing cap 451 to trigger the second proximity switch, indicating that the trainee's body is in a straight state and the next step can be performed.

[0060] Furthermore, if Figure 7 and Figure 8 As shown, it also includes a seat mounting assembly 5, which is located on the side of the seat back 311 away from the seat bottom plate 312, that is, the back side of the seat back 311 is used for installation and fixation, and the seat body 31 also includes a first horizontal connecting plate 51 and a second horizontal connecting plate 52 for fixing the seat back 311 on the seat mounting assembly 5, and the seat mounting assembly 5 is arranged along the height direction of the seat back 311, and the first horizontal connecting plate 51 and the second horizontal connecting plate 52 are respectively arranged at both ends of the seat back 311.

[0061] According to a specific embodiment provided by the present invention, the first horizontal connecting plate 51 and the second horizontal connecting plate 52 are arranged parallel to each other and are in a horizontal state. The specific shapes of the first horizontal connecting plate 51 and the second horizontal connecting plate 52 are not limited here. The length of the first horizontal connecting plate 51 and the second horizontal connecting plate 52 matches the width of the seat back 311. The first horizontal connecting plate 51 and the second horizontal connecting plate 52 are respectively located at the upper part and the lower part of the seat back 311. The first horizontal connecting plate 51 and the second horizontal connecting plate 52 are both fixed to the back of the seat back 311 by fasteners.

[0062] Furthermore, the seat mounting assembly 5 includes two seat connecting plates 66 arranged parallel to each other. The first horizontal connecting plate 51 fixes two oppositely arranged connecting plate supports 53. The connecting plate supports 53 have connecting grooves on their sides. Each connecting plate support 53 corresponds to one of the seat connecting plates 66, and the connecting plate supports 53 are fixedly connected to the connecting ridges of the seat connecting plates 66 through the connecting grooves.

[0063] The second horizontal connecting plate 52 is fixed with a transmission shaft connecting member 54 . The transmission shaft connecting member 54 is located between two seat connecting plates 66 , and both ends of the transmission shaft connecting member 54 are fixed to a seat connecting plate 66 respectively.

[0064] According to a specific embodiment provided by the present invention, the seat connecting plate 66 is distributed along the height direction of the seat, and the two connecting plate supports 53 are distributed horizontally, corresponding to one seat connecting plate 66 respectively. The two connecting plate supports 53 are fixed to the back side of the first horizontal connecting plate 51 by fasteners, and the other end of the connecting plate support 53 is fixedly connected to the seat connecting plate 66.

[0065] The transmission shaft connector 54 is used to connect to the power transmission structure of the parachute platform 1 to provide power to the ejection seat. The transmission shaft connector 54 is located between the two seat connecting plates 66, and the two ends of the transmission shaft connector 54 are respectively fixed to a seat connecting plate 66 by fasteners. The transmission shaft connector 54 can also be fixed to the seat back plate 311.

[0066] Furthermore, if Figure 2 and Figure 8 As shown, the seat also includes a head support assembly 6 disposed above the seat back plate 311, the head support assembly 6 including a headrest 61, a head frame plate 62, and a head pad 63. The head pad 63 matches the shape of the head frame plate 62 and is fastened to one side of the head frame plate 62. The headrest 61 is padded on the head pad 63, and the headrest 61 is made of a flexible material.

[0067] The head frame 62 is secured to both sides with first frame connectors 64, which are respectively secured to the seat connection plate 66. The head frame 62 has a closing structure at its lower portion, secured to both sides with second frame connectors 65. The second frame connectors 65 are located below the first frame connector 64 and secured to the seat connection plate 66 on the side away from the seat back panel 311. The first and second frame connectors 64, 65 are respectively disposed at the upper and lower portions of the seat head frame 62. The provision of the first and second frame connectors 64, 65 secures the head support assembly 6 to the seat connection plate 66.
