[0002] The emergency conference cabin (outdoor space station) can quickly establish a corresponding emergency command and meeting system to ensure the transmission of image, audio, video and other data between the scene of the emergency and local experts and the rear command and control center, forming communication between the front-line emergency conference command system and the rear command and control dispatch system. The application of the emergency double-expansion conference cabin improves the accuracy and flexibility of various departments in handling emergencies, and provides a strong guarantee for various departments to deal with natural disasters and emergencies in a timely manner.

[0003] In actual use, it is necessary to transport the larger conference cabin using a transport vehicle, and the internal space of the conference cabin is large. At this time, the internal space of the cabin needs to be expanded.

The general cabin only limits the expansion cabin by the self-locking of the motor, which not only increases the operating load of the motor, but also reduces the stability of the expansion cabin. When the motor is damaged, the expansion cabin cannot be limited and cannot be moved. Summary of the Invention

[0017] Beneficial effects of the present invention: 1. By setting a manual-automatic alternating part, the driving motor is started to make the second hexagonal sleeve drive the second hexagonal insert to rotate, thereby making the hexagonal shift rod drive the worm to rotate, and the engagement of the worm and the worm wheel makes the driving shaft drive the guide wheel inside the driving chamber to rotate, so that the movement of the cabin frame can be automatically controlled.

When the first pawl is engaged with the first ratchet wheel, the second pawl is unable to limit the second ratchet wheel, and the rotating ring will rotate counterclockwise relative to the positioning rod. Similarly, when the first pawl is engaged with the first ratchet wheel, the rotating ring will swing back and forth, and the positioning rod can only rotate counterclockwise, so that the moving direction of the cabin frame can be controlled. At the same time, because one end of the telescopic plate is fixedly connected to the rotating ring, the telescopic plate will form a force-saving lever effect when it swings, thereby reducing the force required to manually drive the cabin frame to move, thereby further increasing the efficiency of manually operating the cabin frame movement. 3. By providing a stable locking piece and a contact control unit, when the cabin frame is extended toward both sides of the space station body, the fixed contact piece and the movable contact piece are in a separated state. At this time, when the telescopic cylinder is extended, the top plug rod supports the cabin frame moving out of the space station body. When the cabin frame is retracted into the space station body, the fixed contact piece and the movable contact piece come into contact, so that the second sleeve and the first sleeve are in a connected state. Then, the telescopic cylinder is activated, and the locking plug rod is inserted into the locking hole. In this way, the cabin frame can be locked and limited, further increasing the stability of the cabin frame. 4. By setting a contact control unit, the normally closed solenoid valve is energized and opened when the fixed contact piece contacts the moving contact piece, thereby accurately controlling the opening and closing timing of the normally closed solenoid valve.

Slide rails 5 are installed on both sides of the cabin frame 2. A drive compartment 4 is provided inside the space station body 1. The drive compartment 4 is provided with a guide wheel that engages with the slide rails 5. The slide rails 5 drive the cabin frame 2 to move by rotating the guide wheel. A connecting plate 6 is mounted on one end of the cabin frame 2 away from the space station body 1; The manual-automatic switching part is provided at the bottom of the space station body 1 and is used to switch the driving mode of the cabin frame 2; A stabilizing locking member is provided on the inner side of the cabin frame 2 to increase the stability of the cabin frame 2 after it is stored inside the space station body 1; The secure locking member includes a telescopic cylinder 806, a second sleeve 810, a top stopper rod 803, and a stopper plate 802. The telescopic cylinder 806 is mounted on the inner side of the shelter frame 2. The second sleeve 810 is connected to the output end of the telescopic cylinder 806. The top stopper rod 803 extends from the inside of the second sleeve 810 to the outside of the second sleeve 810. The stopper plate 802 is mounted on the bottom end of the top stopper rod 803 and is located below the shelter frame 2. In this embodiment, the manual-automatic alternating member is activated to cause the guide wheel inside the drive bin 4 to drive the slide rail 5 to move horizontally, so that the cabin frame 2 is expanded toward both sides of the space station body 1, thereby increasing the usable space inside the space station body 1, and then the telescopic cylinder 806 is activated, and the second sleeve 810 and the top plug rod 803 are synchronously moved downward by the extension of the telescopic cylinder 806, so that the limit plate 802 is in contact with the ground, so that the side of the cabin frame 2 away from the space station body 1 can be supported, thereby increasing the stability of the cabin frame 2 after extension. Similarly, the cabin frame 2 is stored through the operation of the manual-automatic alternating member, and the telescopic cylinder 806 is activated after the cabin frame 2 is stored, so that the stable locking member can support and connect the cabin frame 2, thereby improving the stability of the cabin frame 2 after storage.

[0033] Example 2 Reference Figures 1 to 5The stable locking component also includes a positioning frame 3, a locking hole 801, a guide hose 814, a normally closed solenoid valve 809, a first sleeve 805, a locking plug rod 804, and a touch control unit. The first sleeve 805 is installed on the inner side of the cabin frame 2 and is located on one side of the telescopic cylinder 806. There are two normally closed solenoid valves 809, which are respectively installed on the outer walls of the first sleeve 805 and the second sleeve 810. The two normally closed solenoid valves 809 are connected by a guide hose 814. The positioning frame 3 is arranged inside the space station body 1 and is located outside the cabin frame 2. The locking hole 801 is opened on the positioning frame 3. The locking plug rod 804 extends from the inside of the first sleeve 805 to the outside of the first sleeve 805. The contact control unit includes a positioning plate 807, a movable plate 808, a return spring 811, a fixed contact piece 812, and a movable contact piece 813. The positioning plate 807 is installed on the top of the connecting plate 6 near the end of the space station body 1. The movable plate 808 is slidably connected to the end of the positioning plate 807 near the positioning frame 3. The two ends of the return spring 811 are respectively connected to one side of the movable plate 808 and the inner wall of the positioning plate 807. The fixed contact piece 812 is installed on the inner wall of the positioning plate 807. The movable contact piece 813 is installed on one side of the movable plate 808 and is located inside the positioning plate 807. The fixed contact piece 812 is electrically connected to the normally closed solenoid valve 809 through a wire, and the moving contact piece 813 is electrically connected to the power supply equipment inside the space station body 1 through a wire. By setting this structure, the normally closed solenoid valve 809 is energized and opened when the fixed contact piece 812 and the moving contact piece 813 come into contact, thereby accurately controlling the opening and closing timing of the normally closed solenoid valve 809.

[0034] In this embodiment, when the cabin frame 2 is extended toward both sides of the space station body 1, the fixed contact piece 812 and the movable contact piece 813 are in a separated state. At this time, the normally closed solenoid valve 809 is in a closed state. At this time, when the telescopic cylinder 806 is extended, the second sleeve 810 and the top plug rod 803 will be moved downward synchronously, so as to support the cabin frame 2 moved out of the space station body 1, so as to improve the stability of the cabin frame 2 after extending out of the space station body 1. Before the cabin frame 2 is retracted into the interior of the space station body 1, the telescopic cylinder 806 is first retracted. When the cabin frame 2 is completely retracted into the interior of the space station body 1, the movable plate 808 will be retracted into the interior of the positioning plate 807 due to the obstruction of the positioning frame 3. At this time, the fixed The contact piece 812 contacts the moving contact piece 813, thereby opening the normally closed solenoid valve 809, so that the second sleeve 810 and the first sleeve 805 are in a connected state, and then the telescopic cylinder 806 is started. At this time, since the bottom of the limit plate 802 is blocked by the inner wall of the positioning frame 3, the second sleeve 810 will move downward relative to the top plug rod 803. At this time, the aqueous solution inside the second sleeve 810 will enter the interior of the first sleeve 805 through the diversion hose 814, thereby moving the locking plug rod 804 away from the first sleeve 805, so that the locking plug rod 804 can be inserted into the interior of the locking hole 801, so that the locking limit of the cabin frame 2 can be achieved, further increasing the stability of the cabin frame 2.

The connecting warehouse 701 is arranged at the bottom of the space station body 1, and the driving shaft 704 is rotatably connected to the inside of the connecting warehouse 701 and is connected to the guide wheel inside the driving warehouse 4. The support frame 708 is installed at the bottom of the space station body 1 and is located on the inner side of the connecting warehouse 701. The worm 719 is rotatably connected to the bottom of the support frame 708. The worm gear 705 is installed at the bottom of the driving shaft 704 and meshes with the worm 719.

The engagement of the worm 719 with the worm gear 705 causes the drive shaft 704 to drive the guide wheel inside the drive chamber 4 to rotate, so that the movement of the cabin frame 2 can be automatically controlled. When the drive motor 703 is damaged, the second screw rod 713 is rotated, so that the sliding frame 714 drives the hexagonal shift rod 715 to move horizontally, thereby separating the second hexagonal insert 717 from the second hexagonal sleeve 718, and at the same time, the first hexagonal insert 711 is inserted into the inner side of the first hexagonal sleeve 709. Thereafter, the forward and reverse rotation unit can be manually driven to cause the hexagonal shift rod 715 to drive the worm 719 to rotate, thereby increasing the driving mode of the cabin frame 2 and preventing the movement of the cabin frame 2 from being affected by the damage of the drive motor 703.

[0036] Example 4 Reference Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 The forward and reverse rotation unit includes a positioning rod 720, a first screw rod 706, a first pawl 722, a rotating collar 721, a translation block 724, a second pawl 725, and a second ratchet 726.

The first screw rod 706 is installed at the end of the transmission shaft 710 away from the first hexagonal sleeve 709. 6 extends from the inside of the positioning rod 720 to the outside of the positioning rod 720. The translation block 724 is sleeved on the outside of the first screw rod 706 and is slidably connected to the positioning rod 720. The rotating collar 721 is rotatably connected to the outer wall of the translation block 724 through a bearing. The second pawl 725 and the first pawl 722 are rotatably connected to both sides of the telescopic plate 702. The connection between the first pawl 722 and the rotating collar 721 and the connection between the second pawl 725 and the rotating collar 721 are both clamped with a torsion spring; The forward and reverse rotation unit further includes a telescopic plate 702 and a splicing block 707. One end of the telescopic plate 702 is disposed on the outer wall of the rotating collar 721 and is fixedly connected to the rotating collar 721.

When the second pawl 725 is engaged with the second ratchet wheel 726, the rotating ring 721 swings back and forth. At this time, the rotating ring 721 drives the second ratchet wheel 726 to rotate when it swings clockwise, so that the transmission coupling 710 rotates synchronously with the second ratchet wheel 726. When the rotating ring 721 swings counterclockwise, the second pawl 725 cannot limit the second ratchet wheel 726. When the first pawl 722 is engaged with the first ratchet wheel 723 , the rotating collar 721 will rotate counterclockwise relative to the positioning rod 720 . Similarly, when the first pawl 722 is engaged with the first ratchet wheel 723 , the rotating collar 721 will swing back and forth. At this time, the positioning rod 720 can only rotate counterclockwise, so that the moving direction of the cabin frame 2 can be controlled. At the same time, since one end of the telescopic plate 702 is fixedly connected to the rotating collar 721 , the telescopic plate 702 will form a force-saving lever effect when swinging, thereby reducing the force required to manually drive the cabin frame 2 to move, and further increasing the efficiency of manually operating the cabin frame 2 to move.
