[0002] Televisions are large-screen display products widely used in various industries. They store or display all kinds of information, including personal private data, corporate confidential documents, and national security data. Currently, most network data is connected and transmitted via WiFi. WiFi is a wireless transmission signal, which is difficult to block and can transmit over long distances. While it has certain advantages in normal use, it is also relatively easy to be cracked, leading to the theft of data or the implantation of viruses, Trojans, ransomware, etc., which can cause incalculable losses to individuals, businesses, and countries.

[0003] In recent years, optical signal transmission has effectively prevented the use of WIFI and the theft of wireless signals. However, there are still many problems to be solved in televisions. The application scenario of optical signals is to use the lighting in the house to add a network signal source, and use the light to transmit the signal. A receiver is designed on the television to transmit the network signal.

[0004] However, the main light is usually located in the center of the living room, while the TV and main unit box are usually close to the wall, so the light received is at an angle, which affects the efficiency of optical network signal reception. Utility Model Content

[0039] In recent years, optical signal transmission has effectively prevented the use of Wi-Fi and avoided issues such as wireless signal theft. However, there are still many problems to be solved when using it on televisions. The application scenario of optical signals is to use home lighting as a network signal source, using the light rays to transmit the signal, and designing a receiver on the television to transmit the network signal. However, the main light is usually located in the center of the living room, and the television and the host box are usually close to the wall, so the received light is at an angle, which affects the efficiency of optical network signal reception.

[0040] This utility model proposes a secondary screen component.

[0041] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the sub-screen assembly 100 includes a main housing 1 and a sub-screen 2. The sub-screen 2 includes a screen housing 21, in which an optical signal module 3 is provided. An interactive side end is formed on the screen housing 21, and the optical signal module 3 can emit and receive optical signals at the interactive side end. The screen housing 21 is rotatably mounted on the main housing 1 so that the tilt angle of the end face of the interactive side end relative to the horizontal plane is adjustable.

[0042] The technical solution of this utility model is to install the optical signal module 3 in a rotatable screen housing 21. During the rotation, the end face of the interactive side can be tilted at a certain angle relative to the horizontal surface, so that the end face of the interactive side is tilted and facing the optical signal source in the home, thereby achieving the technical effect of improving the reception efficiency of optical network signals.

[0043] To ensure the interactive end face is oriented diagonally upwards towards the light source (the main living room light, installed at the top center of the living room), one end of the screen housing 21 in the vertical direction is rotatably mounted to the main housing 1 along a horizontally extending axis. The distance between the other end of the screen housing 21 in the vertical direction and the main housing 1 is adjustable, allowing the tilt angle of the interactive end face of the main housing 1 relative to the horizontal plane to be adjusted. A larger distance between the other end of the screen housing 21 in the vertical direction and the main housing 1 results in a larger upward component of the interactive end face's orientation (a smaller angle between the extension direction of the interactive end face and the horizontal plane); conversely, a smaller distance between the other end of the screen housing 21 in the vertical direction and the main housing 1 results in a smaller upward component of the interactive end face's orientation.

[0044] To drive the screen housing 21 to rotate, the sub-screen assembly 100 includes a linear drive device 4 and a connecting rod 5. The linear drive device 4 has a fixed part 41 and a movable part 42 that are linearly and movably mounted. The fixed part 41 is connected to the main housing 1. The movable part 42 is used to push or pull the screen housing 21 to rotate. However, the movable part 42 cannot be directly connected to the screen housing 21 because the movement trajectory of any point on the screen is an arc, while the movement trajectory of the movable part 42 is a straight line. Therefore, one end of the connecting rod 5 is hinged to the movable part 42, and the other end is hinged to the other end of the screen housing 21 in the vertical direction. The connecting rod 5 realizes the transition of driving force and the conversion of movement direction. In another embodiment, a drive motor can be set at the point where the main housing 1 and the screen housing 21 are rotatably connected, and the drive motor directly drives the screen housing 21 to rotate.

[0045] The screen housing 21 has a retracted position and an unfolded position during its rotation stroke; in order to better receive light signals, the end face of the interactive side is tilted upwards corresponding to the retracted position; in order to better receive light signals, and when the human eye views and operates the sub-screen component 100, the human eye position is above the sub-screen component 100, and the end face of the interactive side of the sub-screen 2 is tilted upwards, which also facilitates human eye viewing. When the secondary screen component 100 stops working, in order to prevent dust from falling onto the end face of the interactive side, affecting the viewing experience and the reception of light signals, the end face of the interactive side is oriented in the same direction as the horizontal direction (the extension direction of the end face of the interactive side is the vertical direction, i.e., the direction of gravity) corresponding to the unfolded position, so that the width of the end face of the interactive side in the direction of gravity is 0, and it does not provide a landing point for dust. Since dust is relatively light, a small amount of dust may still adhere to the end face of the interactive side through electrostatic or other means. Therefore, the end face of the interactive side can be tilted downward. Since dust generally falls from top to bottom, tilting the end face downward reduces the possibility of dust contacting the end face.

[0046] Since the secondary screen 2 is for operation and viewing, the screen housing 21 should not be located on the top of the main housing 1. Furthermore, in the retracted position, the extension direction of the interactive side end face is vertical, while the extension direction of the top surface of the housing is horizontal (left-right). Therefore, it is not convenient to install the screen housing 21 on the top of the main housing 1, or the screen would need to protrude from the main housing 1, affecting aesthetics. Therefore, the screen housing 21 can be located on the side of the main housing 1. To further reduce dust accumulation on the interactive side end face, the main housing 1 has a mounting groove 11 located on the outer side of one side wall in the circumferential direction of the housing. The screen housing 21 is rotatably installed within the mounting groove 11. Corresponding to the retracted position, the optical signal module 3 is located within the mounting groove 11. In the retracted position, less dust can contact the interactive side end face, thus ensuring stable and efficient optical signal transmission. On the other hand, embedding the screen housing 21 within the main housing protects the sub-screen 2, and the sub-screen assembly 100 has no obvious protruding parts, making it more aesthetically pleasing and easier to pack and transport. Corresponding to the unfolded position, the optical signal module 3 is at least partially located outside the mounting slot 11, making it easier for the optical signal module 3 to receive optical signals and preventing the mounting slot 11 from blocking the optical signals.

[0047] To further prevent dust from settling on the end face of the interactive side, the main housing 1 includes an upper cover plate 12. The upper cover plate 12 is located above the mounting groove 11 and extends from one side of the mounting groove 11 to the other side in the depth direction of the bottom of the mounting groove 11. The mounting groove 11 is located within the width range of the upper cover plate 12 in the left-right direction. The upper cover plate 12, positioned above the mounting groove 11, allows less dust to fall to the opening of the mounting groove 11.

[0048] In one type of embodiment, please refer to Figure 3 , Figure 4The secondary screen assembly 100 also includes an infrared receiver 6 and a liquid crystal module 7. For better viewing, operation, and signal transmission / reception, in one embodiment, the optical signal module 3, infrared receiver 6, and liquid crystal module 7 are all mounted on the screen housing 21. The optical signal module 3 has a signal receiving unit and a signal transmitting unit. The screen housing 21 has a first groove 211, a second groove 212, and a third groove 213 on the side opposite to the interactive end. The liquid crystal module 7, the optical signal module 3, and the infrared receiver 6 are respectively positioned and mounted in the first groove 211, the second groove 212, and the third groove 213. The liquid crystal module 7 is glued to the first groove 211, fixing the liquid crystal module 7 within the first groove 211. Buckles are provided in both the second groove 212 and the third groove 213 to fix the optical signal module 3 and the infrared receiver 6. The interactive side of the screen housing 21 has a first through hole 214, which communicates with the first groove 211 and is used to expose the liquid crystal module 7. The interactive side of the screen housing 21 has a second through hole 215 and a third through hole 216, which communicate with the second groove 212 and are respectively corresponding to the signal receiving unit and the signal transmitting unit. The second through hole 215 and the third through hole 216 are used to allow light signals to pass through. The interactive side of the screen housing 21 has a fourth through hole 217, which communicates with the third groove 213 and is used to allow infrared signals to pass through.

[0049] To prevent the optical signal module 3 from being installed upside down, thus avoiding misalignment between the signal receiving unit, signal transmitting unit, and the second through hole 215 and third through hole 216, the screen housing 21 also includes two limiting blocks 218. These two limiting blocks 218 are respectively disposed within the second slot 212 and the third slot 213. Both the optical signal module 3 and the infrared receiver 6 have notches a, which correspond to the limiting blocks 218. This ensures that the optical signal module 3 and the signal receiving unit are installed in a unique orientation within the second slot 212 and the third slot 213, thus preventing mistaken installation.

[0050] In addition, the first slot 211 is located between the second slot 212 and the third slot 213, and the sub-screen assembly 100 also includes two rotating shafts 219. Figure 4 The actual shaft structure is not shown in the diagram; 219 marked in the diagram indicates the shaft mounting position. Figure 4(219 refers to the mounting hole for the rotating shaft). Two rotating shafts 219 are coaxially arranged and pass through the sidewalls of the second groove 212 and the third groove 213 respectively, and are fixedly connected to the screen housing 21. Part of the rotating shaft 219 is located within the notch a. The notch a serves two purposes: firstly, it cooperates with the limiting block 218 to prevent fooling, and secondly, it provides clearance for the installation of the rotating shaft 219.

[0051] Since the secondary screen 2 is installed on the outside of the main housing 1, in order to connect the secondary screen 2 to the electrical module, the main housing 1 has a mounting cavity, and the bottom of the mounting groove 11 is provided with a wire-passing hole to connect the mounting cavity and the mounting groove 11; the secondary screen assembly 100 also includes an electrical module and connecting lines, the electrical module is installed in the mounting cavity, and the connecting lines pass through the wire-passing hole to connect the electrical module and the secondary screen 2 respectively. The wire-passing hole can also allow the linear drive device 4 (fixed part 41 installed in the mounting cavity) or the connecting rod 5 to pass through.

[0052] This utility model also proposes a dual-screen display, which includes a secondary screen assembly 100. The specific structure of the secondary screen assembly 100 is as described in the above embodiments. Since this dual-screen display adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The secondary screen assembly 100 includes a main housing 1 and a secondary screen 2. The secondary screen 2 includes a screen housing 21, in which an optical signal module 3 is provided. An interactive side is formed on the screen housing 21, and the optical signal module 3 can emit and receive light signals at the interactive side. The screen housing 21 is rotatably mounted on the main housing 1, so that the tilt angle of the end face of the interactive side relative to the horizontal plane is adjustable.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
