[0034] Among them, on one side of the simulation cabin 1 close to the second fixing frame 17, a stabilizing cylinder 13 is fixedly connected. On the upper side of the fixed shell 10 close to the stabilizing cylinder 13, a motor 12 is fixedly installed. The moving sleeve 8 is slidably connected to the stabilizing cylinder 13.

[0035] On one side of the bottom surface of the simulation cabin 1, a first fixing frame 16 is fixedly connected. At the bottom of the first fixing frame 16, a universal wheel 20 is installed. On the front of the simulation cabin 1, a control console 18 is provided. At the top of the control console 18, a control system 19 is installed.

[0036] During use, place the test article in the simulation cabin 1, start the motor 12, and finally drive the pressing plate 5 to move. Then, cooperate with the shell pusher 4 to facilitate the extrusion of the test article. This device can be used for the simulation experiment test of animal injuries, simulating the equivalent crush injuries and impact injuries suffered by humans under different altitude terrains. The simulation scenarios are diverse, and the simulation data is processed qualitatively and quantitatively. The whole process is completed by computer control, and the operation is simple.

[0037] The impact mechanism includes an air cannon device 21. The model of the air cannon device 21 can be the KQP-B-300L air cannon. One side of the top of the second fixing frame 17 is fixedly installed with the air cannon device 21. The exhaust port of the air cannon device 21 is connected through a connecting pipe 22. The upper part of the connecting pipe 22 near the air cannon device 21 is connected through a bullet inlet 23. A check valve 24 is installed on the outer side of the connecting pipe 22.

[0038] An installation groove is opened inside the second lead screw 9. The connecting pipe 22 is located inside the installation groove. The second lead screw 9 is rotationally connected to the connecting pipe 22. A telescopic pipe 25 is slidably connected to the side of the connecting pipe 22 away from the air cannon device 21. The telescopic pipe 25 is located inside the moving sleeve 8. An installation bearing 26 is installed through a hole in the middle of the pressing plate 5. The telescopic pipe 25 is rotationally connected to the installation bearing 26. The inside of the telescopic pipe 25 is connected to the inside of the simulation chamber 1.

[0039] When simulating impact injuries, by placing an object inside the simulation chamber 1, opening the bullet inlet 23, putting the test projectile into the connecting pipe 22 from the bullet inlet 23, opening the check valve 24, and starting the air cannon device 21, the strong airflow of the compressed gas ejected by the air cannon device 21 pushes the projectile to be ejected through the connecting pipe 22 and the telescopic pipe 25, causing the projectile to impact the object to be tested, which conveniently realizes the simulation of impact injuries.

[0040] When simulating different air pressure conditions, only need to connect the air inlet on the simulation chamber 1 to the air extraction device, and perform different degrees of air extraction on the simulation chamber 1 to meet the test requirements, which is convenient to realize the test of the device at different altitudes (i.e., different air pressures and different oxygen contents) and different temperatures, improving the test comprehensiveness of the device.

[0041] A refrigeration device 27 is installed in the middle of the inner top surface of the simulation chamber 1. The model of the refrigeration device 27 can be a screw water-cooled chiller. Another side of the inner top surface of the simulation chamber 1 is installed with a temperature sensor 28.

The temperature inside the simulation chamber 1 is controlled by the refrigeration device 27, and the temperature is transmitted to the control system 19 through the temperature sensor 28, which is convenient for the test personnel to control the test at different temperatures.

[0042] Working principle:

[0043] Before using this global environment injury simulation device, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown, when using this device, place the test sample in the simulation chamber 1, rotate the turning handle 15. The turning handle 15 rotates the first lead screw 3. Driven by the fixed port plate 2, the first lead screw 3 drives the shell pusher 4 to move, moving the test sample in the simulation chamber 1 into contact with the pressure plate 5. At this time, start the motor 12. Driven by two gears 11, the motor 12 drives the second lead screw 9 to rotate. The second lead screw 9 enables the moving sleeve 8 to move stably under the action of the chute 14. The moving sleeve 8 drives the pressure plate 5 to move, squeezing the test sample.

[0044] The pressure sensor 7 on the pressure plate 5 detects the pressure value between the test sample and the pressure plate 5, and transmits the data to the control system 19. By controlling the rotation speed of the motor 12, the extrusion force of the pressure plate 5 on the test sample can be controlled, thereby obtaining the deformation amount of the test sample under different extrusion forces.

[0045] When simulating impact injuries, place an object inside the simulation chamber 1, open the ammunition inlet 23, put the test projectile into the connecting pipe 22 from the ammunition inlet 23, open the one-way valve 24, and start the air cannon device 21. The strong airflow of the compressed gas ejected by the air cannon device 21 pushes the projectile to eject through the connecting pipe 22 and the telescopic pipe 25, causing the projectile to impact the object to be tested, facilitating the simulation of impact injuries.

[0046] Meanwhile, control the temperature inside the simulation chamber 1 through the refrigeration device 27. The temperature is transmitted to the control system 19 through the temperature sensor 28, facilitating the tester to control tests at different temperatures. When simulating different air pressure conditions, simply connect the air inlet on the simulation chamber 1 to the air extraction device and perform different degrees of air extraction on the simulation chamber 1 to meet the test requirements.

[0047] This device can be used for simulating experimental tests of animal injuries, simulating equivalent crush injuries and impact injuries that humans receive under different altitudes and terrains. The simulation scenarios are diverse, and the simulation data is processed qualitatively and quantitatively. The whole process is completed under computer control, and the system has structural and communication upgrade interfaces reserved for the future.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
