[0007] The working principle of this utility model is as follows: The staff adjusts the device according to the test requirements, sets the test parameters, and then inflates the airbag protective suit with a certain amount of air. After inflation, the machine box is opened, and the drive mechanism moves the human body model upward, making it easier for the staff to put the airbag protective suit on the human body model. After the suit is put on, the machine box is closed, and the drive mechanism moves the human body model downward. Then, the left and right compression mechanisms move synchronously in opposite directions, respectively contacting the left and right sides of the human body model to compress the airbag protective suit on the human body model. Several pressure sensors detect the compression pressure at each part. The left and right compression mechanisms continuously apply pressure, and the average and maximum compression pressures are tested until the airbag protective suit ruptures and loses pressure, at which point the compression stops and the suit returns to its initial position. Several pressure sensors upload the compression test data to the cloud.

[0008] Open the chassis, and the drive mechanism moves the human body model upward. The staff puts the airbag protective suit of the same specification on the human body model. After the suit is put on, close the chassis, and the drive mechanism moves the human body model downward. Then, the positioning and squeezing mechanism moves half a turn forward so that the positioning and squeezing mechanism is facing the left side of the human body model. The right squeezing mechanism moves against the right side of the airbag protective suit on the human body model. Then, the positioning and squeezing mechanism continuously adjusts its position and squeezes the airbag protective suit on the human body model to test the local pressure. If the airbag protective suit ruptures, replace it with a new airbag protective suit of the same specification and repeat the above steps.

Then, the repositioning compression mechanism moves to continuously adjust its position and press against the airbag protective suit on the mannequin to test the local pressure. If the airbag protective suit ruptures, replace it with a new airbag protective suit of the same specification and repeat the above steps to complete the test on the right side of the mannequin.

[0010] When testing the airbag-type protective suit on the front and back sides of the human body model, the drive mechanism moves the human body model to adjust the angle, which facilitates the adjustment and compression mechanism to adjust the position so that it is directly facing the test area.

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] like Figures 1-8 As shown, this airbag-type protective clothing compression testing device includes a housing 1. The bottom of the housing 1 is provided with a left compression mechanism 6, a repositioning compression mechanism 5, and a right compression mechanism 7 arranged from left to right. The left compression mechanism 6 and the right compression mechanism 7 are symmetrically arranged. The repositioning compression mechanism 5 is located in the middle of the bottom of the housing 1. The upper end of the housing 1 is provided with an air pump 2 and a drive mechanism 3. The drive mechanism 3 is located directly above the repositioning compression mechanism 5. Below the drive mechanism 3 is a human body model 4, which is located inside the housing 1. The human body model 4 is provided with several pressure sensors. The air pump 2 is connected to the left compression mechanism 6 and the right compression mechanism 7 through pipes.

[0038] In this embodiment, the staff adjusts the device according to the test requirements, sets the test parameters, and then inflates the airbag protective suit with a certain amount of air. After inflation, the machine box 1 is opened, and the drive mechanism 3 moves the human body model 4 upward, making it easier for the staff to put the airbag protective suit on the human body model 4. After the suit is put on, the machine box 1 is closed, and the drive mechanism 3 moves the human body model 4 downward. Then, the left compression mechanism 6 and the right compression mechanism 7 move in opposite directions synchronously, respectively contacting the left and right sides of the human body model 4 to compress the airbag protective suit on the human body model 4. Several pressure sensors detect the compression pressure of each part. The left compression mechanism 6 and the right compression mechanism 7 continuously increase the pressure, and test the average pressure and maximum pressure of the compression until the airbag protective suit ruptures and loses pressure, then the compression stops and returns to the initial position. Several pressure sensors upload the compression test data to the cloud.

[0039] Open the chassis 1, and the drive mechanism 3 will move the human body model 4 upward. The staff will put on the human body model 4 with an airbag protective suit of the same specification. After the suit is put on, close the chassis 1, and the drive mechanism 3 will move the human body model 4 downward. Then the adjustment and compression mechanism 5 will move half a turn in the forward direction so that the adjustment and compression mechanism 5 is facing the left side of the human body model 4. The right compression mechanism 7 will move to abut against the right side of the airbag protective suit of the human body model 4. Then the adjustment and compression mechanism 5 will move to continuously adjust its position and compress the airbag protective suit on the human body model 4 to test the local pressure. If the airbag protective suit ruptures, replace it with a new airbag protective suit of the same specification and repeat the above steps.

[0040] After completing the test on the left side of the mannequin 4, the right compression mechanism 7 and the adjusting compression mechanism 5 return to their initial positions. Then, the adjusting compression mechanism 5 moves in the opposite direction by half a turn, so that the adjusting compression mechanism 5 faces the right side of the mannequin 4. The left compression mechanism 6 moves to contact the left side of the airbag protective suit of the mannequin 4. Then, the adjusting compression mechanism 5 moves to continuously adjust its position and compress the airbag protective suit on the mannequin 4 to test the local pressure. If the airbag protective suit ruptures, a new airbag protective suit of the same specification is replaced and the above steps are repeated to complete the test on the right side of the mannequin 4.

[0041] When testing the airbag-type protective suit on the front and back sides of the human body model 4, the drive mechanism 3 drives the human body model 4 to move and adjust the angle, so that the positioning and squeezing mechanism 5 can move and adjust the position to face the test area.

[0042] The staff then changed into airbag protective suits of the same specifications, repeated the above steps, conducted multiple tests, obtained the average value of the tests, and used several pressure sensors to detect the compression pressure of each part, and uploaded the compression test data.

[0044] In this embodiment, the double-threaded electric screw 13 drives the moving seat on it to move. The two moving seats drive the protective door 11 at the corresponding position to slide in the sliding groove, so that the protective door 11 opens and closes, preventing fragments from splashing out from the observation port 8 when the airbag protective suit ruptures. The operating table 12 is used to set parameters and display compression test data. The air pump 2 pumps gas into the airbag protective suit through the air pipe 9. The mounting groove 10 is used to install the adjustment compression mechanism 5.

[0045] The drive mechanism 3 includes a fixed bearing 17, a drive gear 18, and a drive motor 19. The fixed bearing 17 and the drive motor 19 are both fixed to the upper end of the housing 1. The drive gear 18 is rotatably mounted on the upper end of the housing 1. A driven gear 16 is rotatably mounted inside the inner ring of the fixed bearing 17. The driven gear 16 meshes with the drive gear 18. An electric push rod 14 is fixed on the driven gear 16. The telescopic end of the electric push rod 14 passes through the driven gear 16 and the fixed bearing 17 and extends into the housing 1. The human model 4 is fixed below the telescopic end of the electric push rod 14. The output shaft of the drive motor 19 is connected to the drive gear 18 through a pulley pair.

[0046] In this embodiment, the output shaft of the drive motor 19 drives the drive gear 18 to move, the drive gear 18 drives the driven gear 16 to move, and the driven gear 16 drives the electric push rod 14 to move, thereby adjusting the position of the human body model 4 and the airbag protective suit. The telescopic end of the electric push rod 14 drives the human body model 4 to move up and down.

[0047] The left extrusion mechanism 6 includes an electric lead screw 15 and an electric lead screw 20. The electric lead screw 15 is located at the bottom inside the housing 1, and the electric lead screw 20 is located at the top inside the housing 1. The electric lead screw 15 and the electric lead screw 20 are arranged symmetrically from top to bottom. Both the electric lead screw 15 and the electric lead screw 20 are provided with a sliding seat 1. A left extrusion die 21 is provided between the two sliding seats 1. The left extrusion die 21 is directly opposite the left side of the human body model 4. The left extrusion die 21 is provided with a die cavity 1. The shape of the die cavity 1 matches the shape of the left side of the human body model 4.

[0048] In this embodiment, the electric lead screw 15 and the electric lead screw 20 move synchronously, driving the corresponding sliding seat 1 to move, thereby driving the left extrusion die 21 to move. The mold cavity of the left extrusion die 21 presses against the airbag-type protective clothing on the left side of the human body model 4.

[0049] The right extrusion mechanism 7 includes an electric lead screw 22 and an electric lead screw 31. The electric lead screw 22 is located at the top inside the housing 1, and the electric lead screw 31 is located at the bottom inside the housing 1. The electric lead screw 22 and the electric lead screw 31 are arranged symmetrically from top to bottom. The electric lead screw 22 is arranged symmetrically from left to right with the electric lead screw 20, and the electric lead screw 31 is arranged symmetrically from left to right with the electric lead screw 15. Both the electric lead screw 22 and the electric lead screw 31 are provided with sliding seats 2. The right extrusion die 23 is located between the two sliding seats 2. The right extrusion die 23 is arranged symmetrically with the left extrusion die 21, and the right extrusion die 23 is directly opposite the right side of the human body model 4. The right extrusion die 23 is provided with a mold cavity 2. The shape of the mold cavity 2 matches the shape of the right side of the human body model 4. The mold cavity 1 and the mold cavity 2 form an extrusion cavity. The size of the extrusion cavity is a proportional enlargement of the size of the human body model 4.

[0050] In this embodiment, the synchronous movement of electric lead screw 22 and electric lead screw 31 drives the corresponding sliding seat 2 to move, thereby driving the right extrusion die 23. The cavity 2 of the right extrusion die 23 abuts against the airbag-type protective suit on the right side of the human body model 4.

[0051] The adjusting extrusion mechanism 5 includes a second drive motor 24, which is fixed in the mounting groove 10. A baffle 25 is fixed on the second drive motor 24, and the upper end face of the baffle 25 is flush with the inner bottom end face of the housing 1. An installation clearance plate 32 is fixed at the end of the output shaft of the second drive motor 24. The lower end face of the installation clearance plate 32 is higher than the upper end faces of the first and second sliding seats. An arc-shaped mounting plate 26 is provided on the outer side of the installation clearance plate 32. A vertically arranged electric lead screw 28 is provided on the installation clearance plate 32. The electric lead screw 28 abuts against the arc-shaped mounting plate 26. An electric lead screw 30 is fixed on the electric lead screw 28. An electric push rod 27 is provided on the electric lead screw 30. An extrusion block 29 is detachably provided on the telescopic end of the electric push rod 27.

[0052] In this embodiment, a compression block 29 of appropriate shape and size is installed according to the test requirements. The output shaft of the second drive motor 24 drives the installation clearance plate 32 to move. The installation clearance plate 32 drives the electric lead screw 28 and the electric lead screw 30 to move. The movement of the second and fourth electric lead screws drives the movement of the fifth electric lead screw 30. The movement of the fifth electric lead screw 30 drives the movement of the second electric push rod 27, so that the second electric push rod 27 and the compression block 29 are directly facing the airbag protective clothing on the left and right sides of the human body model 4. Then, the telescopic end of the second electric push rod 27 drives the compression block 29 to move, so that the compression block 29 presses the airbag protective clothing on the human body model 4 to perform a local compression test. The baffle 25 is used to prevent fragments of the ruptured airbag protective clothing from falling into the installation groove 10. The arc-shaped installation plate 26 is used to support the fourth electric lead screw 28.

[0053] The working principle of this utility model is as follows: The staff adjusts the device according to testing needs, installs or replaces the appropriately shaped extrusion block 29, sets the test parameters, and starts the air pump 2 to pump gas into the airbag protective suit through the air pipe 9. After inflation, the machine box 1 is opened, causing the double-threaded electric screw 13 to move its movable seat. The two movable seats cause the corresponding protective doors 11 to slide in the sliding groove, thus opening the protective doors 11. The drive mechanism 3 drives the human model 4 upward, i.e., the output shaft of the drive motor 19 drives the drive gear 18, which in turn drives the driven gear 16. The driven gear 16 then drives the electric push rod 14, whose telescopic end moves the human model 4 up and down, facilitating the staff to put the airbag protective suit on the human model 4. After putting it on, the machine box 1 is closed, and the drive mechanism 3 drives the human model 4 downward. Subsequently, the left extrusion mechanism 6 and the right extrusion mechanism 7 move synchronously in opposite directions, respectively contacting the... On the left and right sides of the human body model 4, the airbag protective suit on the human body model 4 is squeezed. That is, the electric lead screw 15 and the electric lead screw 20 move synchronously, driving the corresponding sliding seat 1 to move, thereby driving the left extrusion mold 21 to move. The mold cavity 1 of the left extrusion mold 21 squeezes the airbag protective suit on the left side of the human body model 4. The electric lead screw 32 and the electric lead screw 61 move synchronously, driving the corresponding sliding seat 2 to move, thereby driving the right extrusion mold 23. The mold cavity 2 of the right extrusion mold 23 cooperates with the mold cavity 1 of the left extrusion mold 21 to form an extrusion cavity, covering the human body model 4 and the airbag protective suit in the extrusion cavity, squeezing the airbag protective suit on the human body model 4. Several pressure sensors detect the extrusion pressure of each part. The left extrusion mechanism 6 and the right extrusion mechanism 7 continuously apply pressure, and test the average pressure and maximum pressure of the extrusion until the airbag protective suit ruptures and loses pressure, then the extrusion stops and returns to the initial position. Several pressure sensors upload the extrusion test data to the cloud.

[0054] When the machine casing 1 is opened, the drive mechanism 3 moves the mannequin 4 upwards. Workers then put on the mannequin 4 with an airbag-type protective suit of the same specifications. After the suit is on, the machine casing 1 is closed, and the drive mechanism 3 moves the mannequin 4 downwards. Then, the adjusting and pressing mechanism 5 moves forward half a turn, positioning it directly on the left side of the mannequin 4. The right pressing mechanism 7 moves to press against the right side of the airbag-type protective suit on the mannequin 4. The adjusting and pressing mechanism 5 then continuously adjusts its position, pressing against the airbag-type protective suit on the mannequin 4. This is because the output shaft of the drive motor 24 drives the installation clearance plate 32 to move... The installation of the clearance plate 32 drives the electric lead screw 28 and the electric lead screw 30 to move. The movement of the electric lead screw 28 drives the movement of the electric lead screw 30, and the movement of the electric lead screw 30 drives the movement of the electric push rod 27, so that the electric push rod 27 and the compression block 29 are aligned with the airbag protective suits on the left and right sides of the human body model 4. Then, the telescopic end of the electric push rod 27 drives the compression block 29 to move, so that the compression block 29 presses the airbag protective suit on the human body model 4 to test the local pressure. If the airbag protective suit ruptures, a new airbag protective suit of the same specification is replaced, and the above steps are repeated.

[0055] After completing the test on the left side of the mannequin 4, the right compression mechanism 7 and the adjusting compression mechanism 5 return to their initial positions. Then, the adjusting compression mechanism 5 moves in the opposite direction by half a turn, so that the adjusting compression mechanism 5 faces the right side of the mannequin 4. The left compression mechanism 6 moves to contact the left side of the airbag protective suit of the mannequin 4. Then, the adjusting compression mechanism 5 moves to continuously adjust its position and compress the airbag protective suit on the mannequin 4 to test the local pressure. If the airbag protective suit ruptures, a new airbag protective suit of the same specification is replaced and the above steps are repeated to complete the test on the right side of the mannequin 4.

[0056] When testing the airbag-type protective suit on the front and back sides of the human body model 4, the drive mechanism 3 drives the human body model 4 to move and adjust the angle, so that the positioning and squeezing mechanism 5 can move and adjust the position to face the test area.

[0057] The staff then changed into airbag protective suits of the same specifications, repeated the above steps, conducted multiple tests, obtained the average value of the tests, and used several pressure sensors to detect the compression pressure of each part, and uploaded the compression test data.

[0058] In summary, the test parameters can be set and the test data can be displayed through the control panel 12 on the chassis 1, and the test can be performed automatically, which is convenient and efficient. The two protective doors 11 are driven to open and close by the double-threaded electric screw 13, which enhances safety.

[0059] The drive mechanism 3 drives the human body model 4 to move up and down, which facilitates the wearing of protective clothing. It also drives the human body model 4 to rotate and adjust its position, which facilitates local compression testing of the front and rear sides.

[0060] The left compression mechanism 6 and the right compression mechanism 7 work together to compress the airbag protective suit on the human body model 4, achieving overall compression and meeting the testing requirements of airbag protective suits of different specifications. The testing efficiency is high and the test data is comprehensive.

[0061] The position is adjusted by the positioning and compression mechanism 5, and it cooperates with the left compression mechanism 6 and the right compression mechanism 7 respectively to conduct local compression tests on the airbag protective suit, realize multiple tests, and the test data is accurate.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
