[0025] In response to the problem that existing audio and video interaction terminals are not universally compatible, resulting in low collaborative work efficiency and high daily maintenance costs, see [reference needed]. Figure 1-5 A portable, multi-purpose intelligent audio-visual interactive terminal for subways includes a visual recorder 1, a side cover 2, and a first suction element 3. The visual recorder 1 has a sliding cavity 21 in the middle of its horizontal width direction. A sliding shaft 22 is slidably installed in the sliding cavity 21. A columnar protrusion 23 is fixedly installed on the surface of the sliding shaft 22. A U-shaped side cover 2 is installed on the side of the sliding shaft 22 away from the visual recorder 1 near the protrusion 23. A spring 24 is installed on the surface of the protrusion 23 of the sliding shaft 22 near the visual recorder 1. A locking groove 25 is opened on the surface of the side cover 2. A locking block 26 is fixedly installed on the surface of the sliding shaft 22. During the sliding of the sliding shaft 22, the locking block 26 can be located in or pass through the locking groove 25.

[0026] It should be noted that the visual recorder 1 is any recorder capable of video and voice calls in the prior art. Since video and voice call recorders are very mature technologies in the prior art, they will not be described in detail here.

[0027] During operation, the inspection personnel can transmit clear video to the control center and the metro driver through the visual recorder 1, so as to cooperate with the operation and maintenance control center to implement dispatching instructions, and thus facilitate the intelligent assistance to the metro driver to adjust the train speed, change the stopping platform and other important operations.

[0028] In daily use, the user's palm is placed on the back of the visual recorder 1, and the thumb and forefinger press the sliding shaft 22 to make the sliding shaft 22 slide in the sliding cavity 21. This causes the locking block 26 on the surface of the sliding shaft 22 to move away from the locking groove 25, thereby releasing the locking restriction on the side cover 2, allowing the side cover 2 to rotate away from the palm side, so that the side cover 2 can be switched and fixed from the top or bottom position of the visual recorder 1.

[0029] After the side cover 2 is rotated to the top or bottom of the visual recorder 1, the pressing of the sliding shaft 22 is stopped, so that the spring 24 pushes the sliding shaft 22 back to its original position, thereby allowing the locking block 26 to enter the locking groove 25 for locking, thus restricting the side cover 2 to remain in a fixed state.

[0030] It should be noted that the rotating side cover 2 can be switched and fixed at the top and bottom of the visual recorder 1.

[0031] See Figure 1 and 2 The outer surface of the side cover 2 has multiple recesses 27.

[0032] When used by inspection personnel, the side cover 2 rotates to the top of the visual recorder 1, so that the side cover 2 can be located on the top of the visual recorder 1 to block rain during daily use, thereby ensuring that the surface and lens of the visual recorder 1 remain clear, which is beneficial to the clear communication and imaging of the inspection personnel during daily use. In addition, while the side cover 2 blocks light and rain from the top of the visual recorder 1, the recess 27 can guide the water flow, thereby preventing water from accumulating on the top of the visual recorder 1 and flowing disorderly, which would affect the lens imaging of the visual recorder 1.

[0033] Meanwhile, when the subway driver uses the device, the side cover 2 is rotated to the bottom of the visual recorder 1, so that the visual recorder 1 can be stably placed by the side cover 2, increasing the stability of the visual recorder 1 when it is placed upright. This allows the subway driver to place it in any position in the cab, making full use of the limited space of the cab. It facilitates the installation and use of the equipment without damaging or modifying the cab. In addition, it allows the operation and maintenance control center to have an unobstructed and clear view of the subway driver's driving operation, and also facilitates communication and dialogue between the subway driver and the operation and maintenance control center, thereby better assisting the subway driver in driving.

[0034] When used by a subway driver, the visual recorder 1 in this embodiment of the present disclosure is placed upright by the side cover 2. The recess 27 can also facilitate ventilation at the bottom of the visual recorder 1, thereby preventing the visual recorder 1 from overheating and helping to ensure the stable use of the visual recorder 1.

[0035] The top and bottom of the visual recorder 1 and the inner surface of the side cover 2 are both fixedly installed with first suction components 3. The first suction components 3 can fix the side cover 2 when it is rotated to the top or bottom of the visual recorder 1, thereby improving the light and rain protection effect of the side cover 2 on the visual recorder 1, and also serving as a base to support the stability of the visual recorder 1.

[0036] See Figure 1 A second suction element 4 is fixedly installed on the outer wall of the side cover 2 away from the visual recorder 1. The second suction element 4 adopts a suction cup structure, thereby further increasing the stability of the visual recorder 1 when it is placed upright. It should be noted that the suction cup structure is a very mature technology in the prior art, and the specific structure, principle and parameters of the suction cup will not be elaborated on here.

[0037] See Figure 1 and 2 The side cover 2 is fixedly installed with a first fin 28 near the visual recorder 1, and a second fin 29 is fixedly installed vertically on the first fin 28, with the second fin 29 penetrating the side cover 2.

[0038] During the use of the visual recorder 1, the first fin 28 and the second fin 29 can increase the heat dissipation effect of the visual recorder 1, thereby preventing overheating and ensuring stable operation. It should be noted that the first fin 28 and the second fin 29 are made of aluminum, and protective paint or other anti-corrosion coatings can be applied to their surfaces using existing technology to prevent rust.

[0039] The plurality of recesses 27 are located between adjacent fins. During the heat dissipation process of the visualization recorder 1, the plurality of recesses 27 located between adjacent fins can uniformly dissipate heat to the plurality of first fins 28 and second fins 29.

[0040] The first adsorption element 3 is a magnetic stone with opposite polarities attracting each other. The top and bottom of the visualization recorder 1 have the same polarity, while the inner wall of the side cover 2 near the visualization recorder 1 has the opposite polarity to the top and / or bottom of the visualization recorder 1. When the side cover 2 rotates to the top or bottom of the visualization recorder 1, it is fixed by the magnetic stone with opposite polarities attracting each other, thereby positioning the side cover 2. This allows the spring 24 to push up the sliding shaft 22 after the side cover 2 has rotated, and the locking block 26 on the surface of the sliding shaft 22 can smoothly insert into the locking groove 25 for limiting.

[0041] During use by inspection personnel, the subway driver holds the visual recorder 1 with their palm on the back. They then press the sliding rod with their thumb and forefinger to overcome the resistance of the spring 24, causing it to move axially. This disengages the locking block 26 from the locking groove 25, releasing it from its restraint on the side cover 2. The side cover 2 is then rotated to the top of the visual recorder 1 and positioned at the first suction member 3. Pressing the sliding rod stops, causing the spring 24 to push the sliding rod back to its original position, allowing the locking block 26 to re-enter the locking groove 25 and restore its restraint on the side cover 2. Rotating the sliding rod during inspection personnel's movements allows the side cover to be positioned on top of the visual recorder, protecting it from rain. This ensures the visual recorder 1 is easy to carry and use while preventing rainwater from affecting video clarity. This improves video clarity and facilitates video and voice communication between inspection personnel, the maintenance control center, and the subway driver, ultimately providing more efficient, accurate, and intelligent assistance to the subway driver's operation.

[0042] When the subway driver uses the visual recorder 1, the driver holds the recorder 1 with their palm on the back. Then, the driver presses the sliding rod with their thumb and forefinger to overcome the resistance of the spring 24, causing it to move axially. This disengages the locking block 26 from the locking groove 25, releasing it from its restraint on the side cover 2. The driver then rotates the side cover 2 to the bottom of the recorder 1 and positions it against the first suction member 3. Finally, the driver stops pressing the sliding rod, causing the spring 24 to push the sliding rod back to its original position. This allows the locking block 26 to re-enter the locking groove 25, restoring its restraint on the side cover 2. This allows the side cover 2 to be positioned at the bottom of the recorder 1, serving as a base to support the recorder 1 in a standing position. Therefore, when the subway driver uses it, the rotating side cover is located at the bottom of the visual recorder for support, which increases the stability of the visual recorder 1 during installation and placement. This allows the subway driver to place it in any position in the cab, making full use of the limited space of the cab. It facilitates the installation and use of the equipment without damaging or modifying the cab. Furthermore, it allows the operation and maintenance control center to have an unobstructed and clear view of the subway driver's driving operations, and also facilitates communication and dialogue between the subway driver and the operation and maintenance control center, thereby better assisting the subway driver in driving.

[0043] During the use of the visual recorder 1 by the subway driver, the multiple recesses 27, the first fin 28, and the second fin 29 cooperate with each other, so that the multiple recesses 27 can evenly blow air to cool the main body of the visual recorder 1, the first fin 28, and the second fin 29, thereby improving the heat dissipation effect of the main body of the visual recorder 1 during use and helping to improve the stability during use.

[0044] In the event of an emergency, the intelligent audio and video interactive terminal device in this embodiment can ensure clear and unobstructed video footage, facilitating real-time audio and video communication between subway maintenance and inspection personnel, drivers, and the control center, which is conducive to efficient collaborative processing.

[0045] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
