Description

Technical Field

[0001] This utility model relates to the field of hydrological monitoring equipment technology, and more specifically to a novel video conferencing device for a hydrological emergency monitoring command vehicle that can be raised and lowered. Background Technology

[0002] When a hydrological disaster occurs, in order to facilitate real-time monitoring and command of the situation on site, it is necessary for the command personnel to be on-site. For safety and convenience, a hydrological emergency monitoring and command vehicle is used. The hydrological emergency monitoring and command vehicle is equipped with communication equipment, which allows the command personnel to conduct video calls with the command center at the rear, so as to synchronize information and issue commands remotely in a timely manner. When conducting video conferences, the command personnel sit in the back seat of the vehicle, and the monitor is located in the middle of the vehicle, that is, behind the front seats.

[0003] To ensure the effectiveness of video conferencing, the small monitors located behind the front seats are insufficient for practical needs. Therefore, all existing hydrological emergency monitoring and command vehicles are typically modified to include a large-screen monitor with a camera mounted on a bracket in the middle row for audio and video conferencing. To ensure user comfort, the monitor needs to be at eye level with the command personnel in the rear seats. However, due to the complex road conditions at hydrological disaster sites and the monitor's considerable weight, placing it at a high position results in a high center of gravity. This makes the bracket prone to bending or even breaking during vehicle bumps, potentially damaging the monitor or even injuring the rear-seat command personnel. Therefore, existing video conferencing devices need further improvement to meet the demands of actual use. Utility Model Content

[0004] One advantage of this invention is that it provides a novel liftable video conferencing device for hydrological emergency monitoring and command vehicles. The device is installed in the middle row of the monitoring and command vehicle, and is raised when the vehicle is parked and used, and lowered into the protective shell when not in use. On the one hand, this reduces its height and center of gravity, resulting in less torque when the vehicle is bumpy. On the other hand, being located inside the protective shell makes it more stable and protects the display screen, making it more suitable for use in complex front-line command situations.

[0005] One advantage of this invention is that it provides a novel hydrological emergency monitoring command vehicle with a liftable video conferencing device. The device features a multi-screw and multi-linear bearing linkage structure, which ensures the stability and balance of the overall structure, making lifting more stable and adaptable to complex on-site environments. It will not be damaged by bumps, thus improving its practicality.

[0006] One advantage of this invention is that it provides a novel hydrological emergency monitoring command vehicle with a liftable video conferencing device, which has limit switches at both the top and bottom, and can automatically stop after being raised to a suitable position.

[0007] One advantage of this invention is that it provides a novel liftable video conferencing device for hydrological emergency monitoring command vehicles.

[0026] This utility model provides a novel liftable video conferencing device for a hydrological emergency monitoring command vehicle, including a protective shell. Inside the shell is a frame 2, on which a lifting assembly is mounted. A display 1 is mounted at the front of the lifting assembly. The lifting assembly includes several linear guide rails 7, each comprising a guide rail 7 and a bearing seat 8. The upper and lower ends of the guide rails 7 are fixedly connected to the frame 2. The bearing seats 8 are movably mounted on the guide rails 7, and brackets 3 are connected to the sides of the bearing seats 8. The lifting assembly also includes several lead screws 9. A mounting bearing 10 is provided at the upper end of the frame 2, and the upper... The end is rotatably connected to the mounting bearing 10. A lifting nut is movably engaged with the lead screw 9. A mounting plate 6 is mounted on the lifting nut, and the lifting nut is connected to the bracket 3 through the mounting plate 6. A motor 12 is mounted on the lower part of the frame 2. Both ends of the motor 12 are provided with output shafts 14. The other end of the output shaft 14 is connected to a worm gear reducer. The worm gear reducer is connected to the lead screw 9. The motor 12 drives the lead screw 9 to rotate through the output shaft 14 and the worm gear reducer, so as to drive the lifting nut to rise or fall synchronously. Four linear guides 7 are provided. The four linear guides 7 are divided into two groups and are symmetrical. The frame 2 is positioned on both the left and right sides; connecting arms 4 are fixedly installed at both ends of the bracket 3, with the upper ends of the connecting arms 4 connected to the display 1; a limit plate 5 is installed in the middle of the back of the bracket 3, and the middle of the limit plate 5 is connected to the bracket 3 by bolts; horizontally arranged flat plates are provided at both the upper and lower ends of the limit plate 5; an upper limit switch 11 and a lower limit switch 13 are respectively installed on the upper and lower ends of the back of the frame 2, and the upper limit switch 11 and the lower limit switch 13 are located on the same vertical line as the flat plates of the limit plate 5; an opening is provided at the upper end of the protective shell, and sealing plates are provided at both the upper and lower ends of the display 1, the shape and area of ​​which are similar to those of the upper limit switch 1 and the lower limit switch 1. The sealing plate has the same shape and area. When the monitor 1 rises to the top, the sealing plate at the bottom of the monitor 1 is flush with the opening and connected by an interference fit. When the monitor 1 falls to the bottom, the sealing plate at the top of the monitor 1 is flush with the opening and connected by an interference fit. There are two lead screws 9, which are symmetrically installed in the middle of the frame 2. The two lifting nuts are located at the same horizontal height. The front of the protective shell is also provided with several through holes, through which cables and communication cables are passed. The cables and communication cables are electrically connected to the monitor 1. A camera for capturing video is also provided on the upper part of the monitor 1.

[0027] The first embodiment of this utility model is as follows:

[0028] The new type of hydrological emergency monitoring and command vehicle features a retractable video conferencing device, including a protective shell installed in the middle row of the vehicle, behind the front seats and facing the commanders sitting in the back. The device uses a camera on the monitor to capture video information from the commanders in the back. The monitor is connected to a remote control box, which can transmit video signals over long distances, enabling the frontline commanders in the vehicle to conduct video conferences with the command center.

[0029] The shell has a frame 2 inside, such as Figure 1 As shown, a lifting mechanism is provided at the front of the frame 2, and a display 1 is installed at the front of the lifting mechanism. The display 1 can move up and down at the front of the frame 2 under the drive of the lifting mechanism. When in use, it is raised so that the view of the commander sitting in the back row is level with the display, which is convenient and practical. When not in use, it is lowered into the protective shell, which can protect the display 1, reduce its height and center of gravity, and reduce the torque it experiences when the vehicle is bumpy, making it more stable and more suitable for use in complex front-line command.

[0030] Monitor 1 uses a long ultrawide screen, which displays richer and more detailed content, making it suitable for on-site video conferencing. However, due to the greater length of Monitor 1, and the significant swaying and vibration that occurs during the movement of the command vehicle, multiple sets of linear bearings are used to ensure that the raising and lowering of the long ultrawide screen is more stable and that it remains stable after being raised.

[0031] The lifting mechanism includes four linear guide rails 7, which are divided into two groups and symmetrically arranged on the left and right sides of the frame 2, so that the lateral distance of the support force on the display 1 is greater, thereby ensuring stability. The linear guide rail 7 includes a guide rail 7 and a bearing seat 8. The upper and lower ends of the guide rail 7 are fixedly connected to the frame 2, and the bearing seat 8 is movably installed on the guide rail 7. A bracket 3 is connected to the side of the bearing seat 8.

[0032] The lifting mechanism also includes two lead screws 9, which are symmetrically installed in the middle of the frame 2 to drive the mechanism. The upper end of the frame 2 is provided with a mounting bearing 10. The upper end of the lead screw 9 is rotatably connected to the mounting bearing 10. A lifting nut is movably engaged with the lead screw 9. The two lifting nuts are located at the same horizontal height. A mounting plate 6 is installed on the lifting nut. The lifting nut is connected to the bracket 3 through the mounting plate 6.

[0033] A motor 12 is installed at the lower part of the frame 2. Both ends of the motor 12 are provided with output shafts 14. The other end of the output shaft 14 is connected to a reducer 15. The reducer 15 is connected to the lead screw 9. The motor 12 drives the two lead screws 9 to rotate synchronously and the rotation direction of the two lead screws 9 is the same, so as to drive the lifting nut to rise or fall synchronously. Their moving speed is the same. During its rise or fall, it will drive the bracket 3 to move through the mounting plate 6. At the same time, the bracket 3 is connected to the guide rail 7 to ensure smooth movement.

[0034] Meanwhile, the four sets of linear guide rails 7 ensure that the bracket 3 and the display 1 can remain horizontal. This means that when the vehicle vibrates and sways, the bracket 3 can evenly transmit the swaying torque to the four linear guide rails 7 and dissipate it, thus avoiding a large impact on the lead screw 9 and the lifting nut, ensuring the safety and lifespan of the structure.

[0035] Connecting arms 4 are fixedly installed at both ends of the bracket 3. The upper end of the connecting arm 4 is connected to the display 1. The bracket 3 and the display 1 are connected through the connecting arm 4, which facilitates disassembly and maintenance on the one hand, and facilitates the transmission of force on the other hand.

[0036] like Figure 2 As shown, a limiting plate 5 is installed in the middle of the back of the bracket 3. The middle of the limiting plate 5 is connected to the bracket 3 by bolts. Both the upper and lower ends of the limiting plate 5 are provided with horizontally arranged flat plates, and the two flat plates at the upper and lower ends are respectively flush with the upper and lower ends of the bracket 3.

[0037] like Figure 3 As shown, upper limit switch 11 and lower limit switch 13 are respectively mounted on the upper and lower ends of the back of frame 2. Upper limit switch 11 and lower limit switch 13 are located on the same vertical line as the plate of limit plate 5. Upper limit switch 11 and lower limit switch 13 are electrically connected to motor 12 through PLC controller. When the upper plate touches upper limit switch 11, motor 12 stops working, so that display 1 stops at the predetermined position. At this time, the sealing plate at the bottom of display 1 is flush with the opening and connected by interference fit. The sealing plate and the opening form a flat plane, which maintains the aesthetics.

[0038] When the lower plate touches the lower limit switch 13, the motor 12 stops working, causing the display 1 to stop at the predetermined position. At this time, the upper cover plate of the display 1 is flush with the opening and connected by an interference fit. The display 1 returns to the inside of the housing, which can protect the display 1 and save space, making it more suitable for use in complex front-line command. At the same time, the flush cover plate and the opening form a flat plane, which is more aesthetically pleasing and prevents external debris from entering the housing, thus avoiding affecting the normal operation of the internal structure.

[0039] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
