[0044] like Figure 1 As shown, the walk-in airbag detonation test device of this embodiment includes a support frame 1, and the front and rear of the support frame 1 are respectively equipped with lifting doors 31, and the left and right sides of the support frame 1 are respectively installed with incubators 5, which are sealed and equipped with a temperature adjustment system, and the left and right sides of a single incubator 5 are respectively equipped with doors for entry and exit; a top plate 3 is installed on the top surface of the support frame 1 to form a normal temperature room, and the normal temperature room and the incubators 5 on both sides are arranged closely and located on the same straight line; it also includes a mobile platform system 2 embedded in the ground, the mobile platform system 2 extends from the normal temperature room to the inside of the incubators 5 on both sides, and the mobile platform system 2 automatically moves the vehicle into the incubator 5; the mobile platform system 2 also includes a side shift plate 29, the side shift plate 29 is located at the junction of the normal temperature room and the incubator 5, and the side shift plate 29 is closed below the door of the incubator 5 along the front and rear direction.

[0045] In this embodiment, the vehicle can be automatically transferred to the temperature chamber 5 via the mobile platform system 2 for testing, and according to actual test requirements, two temperature chambers 5 or even a normal temperature chamber can be used together for testing.

[0046] In actual operation, the vehicle equipped with the airbag detonation system can be manually moved to the mobile platform system 2 located in the normal temperature room, and then the mobile platform system 2 can move the vehicle to the corresponding temperature box 5; according to actual operation requirements, vehicles with different or the same test requirements can be moved to the temperature boxes 5 on both sides in turn for simultaneous testing.

[0047] In this embodiment, by setting the side shift plate 29, after the mobile platform system 2 transfers the vehicle to the incubator 5, the front and rear side shift plates 29 can move toward each other and close under the door of the incubator 5, helping to ensure the sealing of the incubator 5 during the test.

[0048] In this embodiment, the normal temperature room is arranged adjacent to the temperature boxes 5 on both sides, and the overall layout is compact and reasonable, and meets and facilitates the transfer and test operation of the vehicle during the test.

[0049] Camera assemblies 6 are evenly distributed on four directions inside the constant temperature room, and camera assemblies 6 are evenly distributed on the front exterior and rear exterior of a single incubator 5, so as to enable image acquisition from multiple angles and directions during the test; windows 56 are sealed and installed on the front wall and the rear wall of the incubator 5, and the camera assemblies 6 take images toward the inside of the incubator 5 through the windows 56.

[0050] In this embodiment, by placing the camera assembly 6 outside the temperature box 5, the influence of high and low temperature and blast test on the camera assembly 6 is effectively avoided, the stability and reliability of image acquisition of the camera assembly 6 are effectively guaranteed, and the service life of the camera assembly 6 is guaranteed.

[0051] All camera assemblies 6 inside the normal temperature room and outside the temperature box 5 are supported on the ground via the camera support assembly 4 .

[0052] In this embodiment, all camera assemblies 6 are supported on the ground via the camera support assembly 4, which effectively ensures the structural reliability of the arrangement and movement of the camera assemblies 6.

[0053] In this embodiment, the mobile platform system 2 is independently embedded in the ground, the incubator 5 and the constant temperature chamber are independently fixed on the ground, and the camera assembly 6 is fixed to the ground via the camera support assembly 4. By independently fixing each component to the ground, mutual interference during operation or testing is effectively reduced or even avoided, thereby effectively ensuring the stability of each component.

[0054] like Figure 2 As shown, the structure of the camera support assembly 4 is as follows: it includes vertical brackets 41 respectively arranged in front of and behind the incubator 5, and a longitudinal beam 1 44 is installed between the corresponding vertical brackets 41, and the longitudinal beam 1 44 spans the top surface of the incubator 5; a cross beam 46 is installed between the corresponding vertical brackets 41 of the incubators 5 on both sides, and a longitudinal beam 2 45 is installed between the cross beams 46, and the cross beam 46 and the longitudinal beam 2 45 are arranged at the top of the normal temperature chamber; a lateral moving mechanism 42 is installed on each of the single vertical brackets 41, and a camera assembly 6 for taking images toward the inside of the incubator 5 is installed on the lateral moving mechanism 42 via a supporting unit 1 43; a horizontal moving mechanism 47 is installed on the cross beam 46 and the longitudinal beam 2 45 along their respective length directions, and a camera assembly 6 facing the inside of the normal temperature chamber is installed on the horizontal moving mechanism 47 via a supporting unit 2 48.

[0055] In this embodiment, a support unit 43 is arranged by supporting a vertical bracket 41 through a horizontal moving mechanism 42 to install a camera assembly 6 for taking images toward the inside of the incubator 5, thereby achieving reliable installation of the camera assembly 6 outside the incubator 5; in actual use, the camera assembly 6 can be adjusted and moved horizontally through the operation of the horizontal moving mechanism 42.

[0056] In this embodiment, the camera assembly 6 is installed and arranged inside the normal temperature room by arranging the horizontal beam 46 and the second longitudinal beam 45 inside the normal temperature room.

[0057] like Figure 3 As shown, the support unit 43 includes a transverse shift seat 431 slidably mounted between the transverse moving mechanisms 42, the transverse shift seat 431 is arranged vertically, and a lifting seat 432 is slidably mounted on the transverse shift seat 431 via a lifting driving power 433, and a camera assembly 6 is mounted on the lifting seat 432.

[0058] In this embodiment, the upper and lower parts of the transverse shift seat 431 are respectively slidably installed on the transverse moving mechanism 42 to achieve stable support, effectively ensure the reliability of the transverse shift seat 431 during transverse movement, and help ensure the reliability of the camera assembly 6 during use.

[0059] In this embodiment, the lateral moving mechanism 42 can be a combination of a laterally arranged linear module and a guide rail, or it can be other driving mechanisms that can stably move the linear lateral displacement seat 431 laterally; the lifting drive power 433 can be a linear drive power such as a cylinder, an electric cylinder, or an oil cylinder, or it can be a combination structure of a motor and a lead screw, which can realize the stable up and down movement of the lifting seat 432.

[0060] In this embodiment, two groups of horizontal moving mechanisms 42 are respectively arranged on two relatively arranged groups of vertical brackets 41. A single group of horizontal moving mechanisms 42 corresponds to the movement and support of a single group of camera components 6, effectively ensuring the independent movement, adjustment and use of the camera components 6 without interfering with each other.

[0061] like Figure 4 As shown, the supporting unit 48 includes a moving seat 481 slidably mounted on the horizontal moving mechanism 47, and a lifting driving power 482 is installed on the moving seat 481. The lifting driving power 482 is a cylinder, an electric cylinder or an oil cylinder in this embodiment with the output end facing downward. A lifting seat 483 is installed at the output end of the lifting driving power 482, and a camera assembly 6 is installed on the lifting seat 483.

[0062] In this embodiment, through the action of the lifting drive power 2 482, the support unit 2 48 and the supported camera assembly 6 can be collected in the upper part of the normal temperature room, and sufficient space is reserved in the lower part of the normal temperature room, which will not affect the daily operations such as the movement of the vehicle on the mobile platform system 2; when it is necessary to use the normal temperature room for testing, the lifting drive power 2 482 can be operated to make the camera assembly 6 move downward for easy use.

[0063] like Figure 5 As shown, the interior of the incubator 5 is equipped with background cloth 57 along the front edge and the rear edge respectively. The background cloth 57 is folded and unfolded via a support frame 55. The background cloth 57 is used in conjunction with the corresponding camera assembly 6. The structure of the support frame 55 is as follows: it includes cantilever frames 551 installed on the inner wall of the incubator 5 at intervals on the left and right, and a folding and unfolding track 552 corresponding to the background cloth 57 is installed between the cantilever frames 551, as shown in FIG. Figure 6 As shown, the background cloth 57 can be moved in the same direction along the stowage and deployment track 552 to be stacked together, or can be moved in the opposite direction along the stowage and deployment track 552 to be unfolded.

[0064] In this embodiment, the background cloth 57 can be switched between the retracted and extended states via the support frame 55, so that the camera assembly 6 can be used in conjunction with the background cloth 57, effectively improving and ensuring the effect of the camera assembly 6 in capturing images, and helping to reduce interference.

[0065] In this embodiment, a background cloth 57 can also be arranged on the inner wall of the normal temperature room. Similar to the arrangement of the camera assembly 6 in the normal temperature room, the background cloth 57 in the normal temperature room can be arranged in the form of a roller blind, which can be retracted and extended by lifting and lowering to facilitate outflow of space below the normal temperature room. During the test, the roller blind below can be used to ensure the use of the camera assembly 6 for imaging.

[0066] A lighting system 53 is also installed on the top of the incubator 5 to effectively ensure lighting during the test and facilitate imaging; side doors 52 for entry and exit are installed on the left and right sides of the incubator 5 through an opening and closing door mechanism 54; a transition chamber 51 is also installed on the outer wall of a single incubator 5, and closed doors are installed between the transition chamber 51 and the incubator 5, and between the transition chamber 51 and the outside world. While ensuring the sealing and insulation requirements, it is convenient for personnel to enter and exit during the test.

[0067] like Figure 7As shown, the structure of the mobile platform system 2 is as follows: it includes a platform support 22 embedded in the ground, a mobile platform 1 21 is installed on the platform support 22 and moves between the normal temperature room and the incubator 5 along the left-right direction, and a mobile platform 2 25 is also installed on the platform support 22 and moves along the front-back direction, and the mobile platform 2 25 moves between the front door and the interior of the normal temperature room; a main cover plate 27 is installed on the ground at the front door of the normal temperature room, and a follower plate 28 is connected to the front edge of the mobile platform 25, and the follower plate 28 is accommodated under the main cover plate 27 or the follower plate 28 moves to be flush with the rear of the main cover plate 27; side cover plates 23 are installed on the ground at the four corners where the normal temperature room and the incubator 5 are connected, and side shift plates 29 are installed on the bottom surface of the side cover plates 23.

[0068] In this embodiment, when in use, the vehicle can be placed on the mobile platform 21, and then the vehicle is automatically moved to the incubator 5 through the movement of the mobile platform 21, or the vehicle can be placed on the mobile platform 25, and then the vehicle is moved to the normal temperature room through the movement of the mobile platform 25; with the movement of the mobile platform 25, the follower plate 28 will be pulled to move synchronously, so that the ground at the door of the normal temperature room is filled and squared to facilitate the walking of people and the movement of other items; after the mobile platform 21 is transported to the inside of the incubator 5, the side shifting plate 29 can be moved towards each other to fill the ground at the junction of the incubator 5 and the normal temperature room, which effectively helps to ensure the insulation and sealing of the incubator 5 on the one hand, and is also convenient for the walking of people and the movement of items when needed.

[0069] The mobile platform 1 21 is installed on the platform support 22 via the transverse conveying mechanism 24, and the mobile platform 2 25 is installed on the platform support 22 via the longitudinal conveying mechanism 26, so that the mobile platform 1 21 and the mobile platform 2 25 can move independently of each other, which is convenient for actual use.

[0071] It also includes a guide rail 247 arranged along the conveying direction, and the mobile platform 1 21 and the mobile platform 25 are rollingly installed on the guide rail 247 via the guide wheel 248, thereby effectively ensuring the reliability of movement; Fig.10 As shown, the circumferential edge of the guide wheel 248 extends laterally to form a flange 2481, and the flange 2481 is assembled and limited with the guide rail 247 to ensure reliable guidance.

[0072] In this embodiment, the conveying member 241 may be a chain or a synchronous belt structure, and may be equipped with corresponding sprockets or pulleys for transmission.

[0073] like Fig.11 and Fig.12 As shown, a plurality of follower seats 281 arranged at intervals are installed between the front edge of the mobile platform 25 and the rear edge of the follower plate 28. The follower seat 281 includes supports respectively installed on the mobile platform 25 and the follower plate 28, and support rods are installed between the supports for common rotation, so that there can be a height difference between the follower plate 28 and the mobile platform 25 that move synchronously, so that the follower plate 28 can be retracted under the main cover plate 27 or unfolded to be flush with the rear of the main cover plate 27; a wedge block 282 is installed on the platform support 22 located behind the main cover plate 27, and the top surface of the wedge block 282 is inclined backward and upward. The follower seat 281 is guided by the wedge block 282 and moves upward to be flush with the main cover plate 27 while moving backward, thereby effectively ensuring the retraction and expansion of the follower plate 28 during the forward and backward movements.
