[0030] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] See also Figure 1 and Figure 2The utility model provides a display screen shading and fill-in light device, comprising a mounting structure 1, a shading box 2, a camera 3 and a fill-in light (not shown in the figure). The shading box 2 is movably mounted on the mounting structure 1; a window 21 is provided on the side panel of the shading box 2 facing the display screen, and the shading box 2 can be selectively moved toward the display screen so that the display screen is located in the shading box 2 with the help of the window 21; the camera 3 is mounted in the shading box 2, and the camera head of the camera 3 faces the display screen, and is used to shoot the information displayed on the display screen; the fill-in light is mounted on the inner wall of the shading box 2, and is used to fill in light for the display screen.

[0034] In this way, when using the display screen shading and fill-in-light device of the utility model, the display screen shading and fill-in-light device is first installed near the display screen, and when the light is too strong and reflective, the shading box 2 is moved toward the display screen until the display screen is located in the shading box 2 through the window 21, thereby shading the display screen through the shading box 2, avoiding the need for staff to hold an umbrella all the time, reducing the employment cost and the labor intensity of the staff, and also reducing the workload of the staff; by arranging the camera 3 in the shading box 2, the camera 3 is integrated in the shading box 2, and can be directly used as a set during calibration; by arranging the fill-in light, when the optical fiber is too dark, the fill-in light can be turned on to illuminate the display screen so that clear data can be collected, and it can also avoid the staff from holding the fill-in light for fill-in light.

[0035] For ease of explanation, the installation position of the light shielding box 2 is recorded as the initial position. When the light shielding box 2 moves toward the direction close to the display screen until the display screen is located in the box, the position of the light shielding box 2 at this time is recorded as the working position.

[0036] It is understandable that the light shielding box 2 can also be selectively moved from the working position to the initial position in the direction away from the display screen. In addition, in order to achieve light shielding, the light shielding box 2 can be set to a dark color or black, and the light shielding box 2 cannot be made of a light-transmitting material.

[0037] See also Figure 3 In some embodiments, the display screen shading and fill light device further includes a first drive assembly 4, and the first drive assembly 4 includes a first drive motor 41 and a first transmission member 42. The first drive motor 41 is mounted on the mounting structure 1, and the first transmission member 42 is disposed on the outer wall surface of the shading box 2. The output end of the first drive motor 41 is transmission-connected to one end of the first transmission member 42, and the first transmission member 42 is transmission-connected to the shading box 2 to drive the shading box 2 to move toward or away from the display screen. Optionally, the first drive motor 41 is mounted on one end of the mounting structure 1 away from the window 21.

[0038] Among them, the forward rotation of the first drive motor 41 can make the light shielding box 2 move towards the direction closer to the display screen (that is, from the initial position to the working position), and the reverse rotation of the first drive motor 41 can make the light shielding box 2 move away from the display screen (from the working position to the initial position).

[0039] See also Figure 2 and Figure 3 Further, in some embodiments, the first transmission member 42 includes a threaded lead screw 421 and a transmission part 422. One end of the lead screw 421 is connected to the output end of the first drive motor 41; the transmission part 422 is fixedly mounted on the outer wall of the light shielding box 2. The outer peripheral surface of the lead screw 421 is provided with an external thread, and the lead screw 421 is inserted into the internal thread hole of the transmission part 422; the lead screw 421 is extended along the moving direction of the light shielding box 2.

[0040] It should be noted that the transmission part 422 can be fixedly connected to the light shielding box body 2 by fasteners such as screws, and the transmission part 422 can also be set as an integral structure formed integrally with the light shielding box body 2, as long as the two can be fixedly connected.

[0041] In this way, by turning on the first drive motor 41, the output end of the first drive motor 41 drives the lead screw 421 to rotate, and the lead screw 421 drives the transmission part 422 to move along the length direction of the lead screw 421. Since the transmission part 422 is fixedly connected to the light-shielding box body 2, the light-shielding box body 2 moves along the length direction of the lead screw 421, so that the light-shielding box body 2 can move in a direction closer to or away from the display screen, thereby switching the light-shielding box body 2 between the initial position and the working position. When the light-shielding box body 2 is in the initial position, the display screen is located outside the light-shielding box body 2, and when the light-shielding box body 2 is in the working position, the display screen is located inside the light-shielding box body 2.

[0042] See also Figures 1 to 3 In some embodiments, the display screen shading and fill light device also includes two first limit members 5, which are installed at opposite ends of the mounting structure 1 along the moving direction of the shading box 2 at intervals, and the opposite ends of the lead screw 421 are respectively movably arranged through the two first limit members 5.

[0043] Further, the first limit member 5 is a limit plate, and two first through holes are correspondingly provided on the two limit plates, and the lead screw 421 is passed through the two first through holes and the internal threaded hole of the transmission part 422. It can be understood that the aperture of the first through hole is larger than the outer diameter of the lead screw 421, so that the lead screw 421 can move along the first through hole.

[0044] In this way, by providing two first limit members 5 , the radial position of the lead screw 421 can be limited, and the lead screw 421 can be supported at the same time.

[0045] See also Figures 1 to 3In some embodiments, the display screen shading and supplementary light device further includes two second limiters 6 located on both sides of the lead screw 421, the opposite ends of the two second limiters 6 are respectively penetrated through the two first limiters 5, and the transmission part 422 is sleeved on the two second limiters 6. The transmission part 422 is also provided with two second through holes at intervals, the two second through holes are respectively located on both sides of the internal threaded hole of the transmission part 422, and the two second limiters 6 pass through the two second through holes respectively. Further, the opposite ends of the second limiter 6 are connected to the first limiter 5 by threads. Optionally, the second limiter 6 is a limit rod.

[0046] In this way, the second limiting member 6 is provided to limit the position of the transmission part 422 , and at the same time can support the transmission part 422 and guide the movement of the transmission part 422 .

[0047] See also Figure 2 and Figure 3 In some embodiments, the display screen shading and supplementary light device further includes a second driving motor 7 and a focusing structure 8, and the second driving motor 7 is mounted on the shading box 2. The focusing structure 8 is connected to the second driving motor 7 by transmission, and the focusing knob of the camera 3 is fixedly connected to the focusing structure 8, and the focusing structure 8 drives the focusing knob to rotate to adjust the focus.

[0048] See also Figure 2 In some embodiments, the focus adjustment structure 8 includes a first gear 81, a transmission belt 82, a second gear 83 and a fixing member 84. The first gear 81 is connected to the output end of the second driving motor 7 by transmission. The second gear 83 is sleeved on the camera 3. The transmission belt 82 is sleeved on the outer periphery of the first gear 81 and the second gear 83. The fixing member 84 is used to fix the transmission belt 82, the gears and the focus knob. Optionally, the fixing member 84 passes through the transmission belt 82 and the second gear 83 and abuts against the focus knob.

[0049] In this embodiment, the first gear 81, the transmission belt 82 and the second gear 83 are provided to realize the power transmission of the second drive motor 7, so as to focus the camera 3. Of course, the power transmission can also be realized by other transmission devices or transmission components according to the actual usage scenarios and needs, and is not limited to the examples in this embodiment.

[0050] It should be noted that the maximum rotation angle of the first gear 81 is 60°, that is, the second drive motor 7 rotates forward to rotate the first gear 81 30° toward one side of the fixing member 84, and the second drive motor 7 rotates reversely to rotate the first gear 81 30° toward the other side of the fixing member 84.

[0051] In addition, in the present invention, the start and stop and forward and reverse rotation of the first drive motor 41 and the start and stop and forward and reverse rotation of the second drive motor 7 can be achieved through remote control, thereby realizing semi-automatic operation. Remote control only requires adding corresponding control programs.
