[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] An ejection seat simulator, such as Figure 1 , Figure 2 and Figure 4 As shown, including: A seat body 31, wherein the seat body 31 includes a seat back plate 311 and a seat bottom plate 312 located at the bottom end of the seat back plate 311, and a seat cushion is laid on the seat bottom plate 312; and A disengagement mechanism 4 is arranged in close contact with the seat back plate 311, the disengagement mechanism 4 comprises a disengagement plate 41 with a safety belt installed, and the disengagement plate 41 is detachably connected to the seat body 31 through at least two locking components 42; The seat bottom plate 312 is provided with an ejection start mechanism, which is used to control the locking assembly 42 so that the disengagement mechanism 4 can be disengaged from the seat body 31. Specifically, the ejection start mechanism includes a first proximity switch, and by pulling the ejection pull ring 7 of the ejection start mechanism, the first proximity switch receives a signal and feeds it back to the control system, and the control system then controls the electromagnet 423 of the locking assembly 42 to adsorb the locking push rod 424, thereby pulling the locking push rod 424 out of the locking hole of the disengagement plate 41 (the ejection start mechanism can adopt an existing structure, and the present invention will not be repeated in detail).

[0022] According to a specific embodiment provided by the present invention, the ejection seat simulation device 3 of the present invention includes a seat body 31 and a disengagement mechanism 4, the bottom end of the seat back plate 311 is connected to one end of the seat bottom plate 312, a left baffle is arranged on the left side of the seat body 31, and a right baffle is arranged on the right side of the seat body 31, the left baffle is fixed with a left armrest, and the right baffle is fixed with a right armrest, the left baffle and the right baffle are symmetrical in structure, both of which are "L"-shaped structures, and are arranged to fit the side of the seat back plate 311 and the seat bottom plate 312, and are fixed to the side of the seat back plate 311 and the seat bottom plate 312 by fasteners. During ejection simulation training, the trainee sits on the cushion of the seat bottom plate 312, and the back is fixed to the disengagement plate 41 by a safety belt (the safety belt is not shown in the figure), and the safety belt can be arranged in a cross-shaped manner of two safety belts, and the ends are respectively cross-connected at the four corners of the disengagement plate 41, so as to ensure the safety of the trainee.

[0023] In this embodiment, the detachment plate 41 of the detachment mechanism 4 is detachably connected to the seat body 31 through at least two locking components 42. Specifically, the number of locking components 42 can be set to four, which are respectively installed at the four corners of the rectangular seat back plate 311. The life-saving simulation training equipment of the present invention includes ejection and parachute drop processes as a whole. During the ejection process, the detachment mechanism 4 and the seat body 31 are integrally arranged. Until the parachute drop stage, the detachment mechanism 4 is detached from the seat body 31, and the trainee will also be lifted up into the parachuting state together with the detachment plate 41 under the action of the sling. During the ejection simulation training to the parachute drop process, the trainee needs to operate the ejection start mechanism installed on the seat bottom plate 312 to control the locking component 42 so that the detachment plate 41 is detached from the seat body 31.

[0024] 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 landing process.

[0025] 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, the electromagnet 423 is fixed on one side of the locking mounting seat 421, and the locking push rod 424 is arranged on one side of the electromagnet 423. The locking push rod 424 passes through the hole opened in the locking mounting seat 421, the locking spring 422 is sleeved on the outside of the locking push rod 424, and the locking mounting seat 421 is fixed with a spring limiting plate 425, 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.

[0026] According to a specific embodiment provided by the present invention, this embodiment provides a specific structure of a locking component 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, and 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 move. The end of the locking mounting seat 421 away from the electromagnet 423 extends vertically 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.

[0027] The spring limiting plate 425 of the present 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 limiting 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. 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 out from the locking hole provided in the disengagement plate 41. At this time, the disengagement mechanism 4 can be detached from the seat body 31.

[0028] Further, the locking assembly 42 further includes a state detection unit, which includes a first proximity switch 427, the locking mounting seat 421 has a switch mounting plate 426, the switch mounting plate 426 is mounted with the first proximity switch 427, the locking push rod 424 has a contact plate 428, the contact plate 428 can also be used to abut against the locking spring 422, the contact plate 428 is arranged in parallel with the switch mounting plate 426, and the end of the locking spring 422 abuts against 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 can provide a mounting position for the locking spring 422, and can also serve as a structure for triggering the first proximity switch 427.

[0029] 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 release 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.

[0030] A proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When an object (such as a trainer's body or a contact plate) approaches the sensing surface of the switch to the action distance, the switch can be activated without mechanical contact or any pressure, thereby driving DC appliances or providing control instructions to a computer (PLC) device. A proximity switch, also known as a contactless proximity switch, is an ideal electronic switch quantity sensor. When a metal detection object first approaches the sensing area of ​​the switch, the switch can quickly issue electrical instructions without contact, pressure, or sparks, accurately reflecting the position and stroke of the moving mechanism. Even if it is used for general stroke control, it has the advantages of high positioning accuracy, long service life, easy installation and adjustment, and strong adaptability to harsh environments.

[0031] The first proximity switch and the second proximity switch can both adopt 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, which forms 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 a shaping amplifier.

[0032] 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 shell 431, a padlock spring 432 and a spring pin 433; Among them, the padlock shell 431 is a hollow structure, the padlock shell 431 is fixed to the upper part of the detachment plate 41, the end of the padlock shell 431 away from the detachment plate 41 is an open structure, one side of the padlock shell 431 has a cylindrical connecting opening, the cylindrical connecting opening is located on the outside of the padlock shell 431, the spring pin 433 passes through the padlock spring 432, the spring pin 433 extends into the padlock shell 431 from the connecting opening, a padlock end cover 434 is fixed to the connecting opening, 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 penetrate to the other side of the padlock shell 431, and a padlock pull ring 435 is provided at one end of the padlock spring 432 located at the padlock end cover 434.

[0033] 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, and 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.

[0034] 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 open end 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 extends into the padlock shell 431 from the open end, 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).

[0035] Furthermore, the padlock assembly 43 also includes a boosting component 44 installed in the padlock shell 431, and the boosting component 44 is arranged below the spring pin 433. The boosting 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 boosting component 44 can abut the bottom wall of the padlock hole of the padlock plate against the lower part of the spring pin 433, so that 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.

[0036] 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.

[0037] 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.

[0038] Furthermore, the detachment mechanism 4 is equipped with a back sensor assembly 45. Specifically, the number of the back sensor assemblies 45 is set to two, and the back sensor assembly 45 includes a second proximity switch and a pressing cap 451 connected to the second proximity switch, and the pressing cap 451 contacts and cooperates with the back of the trainee. Specifically, the pressing cap 451 passes through a spring, and the spring makes the pressing cap 451 have a tendency to move away from the detachment plate 41. When the trainee's body contacts the pressing cap 451, the pressing cap 451 is pressed into the detachment plate 41 to cooperate with the second proximity switch.

[0039] 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, so that the pressing cap 451 triggers the second proximity switch, indicating that the trainee's body is in a straight state and the next step can be performed.
