[0044] The embodiment of the present application provides a video connection structure. The video connection structure of the present application will be described in detail below with reference to the accompanying drawings.

[0045] Refer to Figures 1 to 4 , which shows a schematic structural diagram of a video connection structure provided by an embodiment of the present application. Refer to Figure 5 , which shows a cross-sectional view of a video connection structure provided by an embodiment of the present application.

[0046] As Figures 1 to 5 shown, the present application provides a video connection structure, including a connection assembly 2; the connection assembly 2 includes a power line 21, a video line 22, and a protective shell 23. The power line 21 and the video line 22 are located inside the protective shell 23, and the power line 21, the video line 22, and the protective shell 23 are an integrally injection-molded structure.

[0047] In the embodiment of the present application, since the power line 21 and the video line 22 are arranged inside the protective shell 23, and the power line 21, the video line 22, and the protective shell 23 are an integrally injection-molded structure, an integrated connection assembly 2 can be formed. In this way, during the installation process of the display device, since the connection assembly 2 of the video connection structure is integrated, the problem of wire harness entanglement will not occur, which is beneficial to improving the convenience of installation and maintenance of the display device. In addition, integrally injection-molding the power line 21, the video line 22, and the protective shell 23 can also improve the overall structural strength of the connection assembly 2, which is beneficial to improving the service life of the connection assembly 2.

[0048] In practical applications, the injection molding process of the power line 21, the video line 22, and the protective shell 23 is generally as follows: First, the power line 21 and the video line 22 are placed into the injection mold; then, a plastic raw material is injected into the injection mold to form a protective shell 23 that wraps the power line 21 and the video line 22 inside the injection mold.

[0049] It should be noted that in the embodiments of the present application, the first direction X refers to the X-axis direction, the second direction Y refers to the Y-axis direction, and the third direction Z refers to the Z-axis direction, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs. In addition, the power cord 21 and the video cable 22 of the present application can both adopt existing products. Among them, the video cable 22 usually has a shielding structure, so that electromagnetic interference between the power cord 21 and the video cable 22 can be effectively avoided, ensuring the stable transmission and clear display of video signals. Specifically, the video cable 22 usually includes a conductor, an insulating layer, a shielding layer, and a protective layer arranged in sequence from the inside to the outside. Among them, the conductor is used to transmit video signals; the insulating layer is used to prevent electrical contact between conductors or between conductors and the external environment, thereby avoiding signal loss and electromagnetic interference; the shielding layer is usually made of a metal (such as copper or aluminum) braided mesh or foil to achieve electromagnetic shielding; the protective layer is used to protect the internal structure from physical damage and the influence of the external environment.

[0050] In some alternative embodiments of the present application, the power cord 21 and the video cable 22 are arranged in parallel. In this way, on the basis of meeting electromagnetic shielding, arranging the power cord 21 and the video cable 22 in parallel can optimize the space utilization, further reduce the size of the connection component 2, and is beneficial to the miniaturization of the video connection structure.

[0051] In some alternative embodiments of the present application, the video connection structure further includes: a connector 1, a power cord port 11, and a video cable port 12; the connector 1 is connected to the connection component 2; the power cord port 11 and the video cable port 12 are both arranged at one end of the connector 1 facing away from the connection component 2; among them, the power cord port 11 and the position of the power cord 21 are opposite and electrically connected to each other, and the video cable port 12 and the position of the video cable 22 are corresponding and electrically connected to each other.

[0052] In the embodiments of the present application, since the power cord port 11 and the video cable port 12 are provided, and the power cord port 11 is electrically connected to the power cord 21, and the video cable port 12 is electrically connected to the video cable 22. In this way, the video connection structure can be connected to an external display device or other devices through the power cord port 11 and the video cable port 12, so as to achieve reliable transmission of the current of the video signal.

[0053] It should be noted that the video cable port 12 has a first cross-section perpendicular to the third direction Z, and the power cord port 11 has a second cross-section perpendicular to the third direction Z. Among them, the shapes of the first cross-section and the second cross-section can both be circular, rectangular, elliptical, triangular, polygonal, or irregular shapes, which are not limited herein, and those skilled in the art can adjust according to actual needs. It can be understood that when the shapes of the first cross-section and the second cross-section are different, it is convenient for the staff to identify and distinguish the power cord port 11 and the video cable port 12, and the problem of wrong wiring can be effectively avoided. In one of the embodiments, such asFigure 2 As shown, the shape of the first cross-section is circular, and the shape of the second cross-section is rectangular. In order to further reduce the size of the connector 1, the center line of the connector 1 is parallel to but does not coincide with the axis of the video cable port 12, that is, the video cable port 12 is offset relative to the center of the connector 1.

[0054] In some alternative embodiments of the present application, the connector 1 has a first direction X; the video cable port 12 and the power cable port 11 are spaced along the first direction X; in a plane perpendicular to the first direction X along the first direction X, the orthographic projection of the video cable port 12 and the orthographic projection of the power cable port 11 partially overlap.

[0055] In the embodiments of the present application, since in a plane perpendicular to the first direction X along the first direction X, the orthographic projection of the video cable port 12 and the orthographic projection of the power cable port 11 partially overlap, that is, at least part of the power cable port 11 is arranged to avoid the orthographic projection of the video cable port 12. Figure 2 It can be seen that when at least part of the power cable port 11 avoids the orthographic projection of the video cable port 12, that is, when the power cable port 11 moves to the left (that is, along the second direction Y away from the video cable port 12), the distance between the power cable port 11 and the video cable port 12 along the first direction X can be increased. In this way, by moving the power cable port 11 upward (that is, along the first direction X towards the video cable port 12), the power cable port 11 can be arranged as close as possible to the video cable port 12 as a whole, thereby reducing the size of the connector 1, which is beneficial to the miniaturization of the video connection structure.

[0056] In some alternative embodiments of the present application, the power cable 21 includes a first power cable 211 and a second power cable 212, and the power cable port 11 includes a first power cable port 111 electrically connected to the first power cable 211, and the power cable port 11 further includes a second power cable port 112 electrically connected to the second power cable 212.

[0057] In the embodiments of the present application, through the corresponding electrical connection between the first power cable port 111 and the first power cable 211, and between the second power cable port 112 and the second power cable 212, reliable transmission of current can be achieved. Among them, the two power cables 21, that is, the first power cable 211 and the second power cable 212 are respectively the positive and negative poles or the live wire and the neutral wire, so as to provide a reliable channel and a complete circuit for the current to enable reliable transmission of the current.

[0058] It should be noted that, as Figure 3As shown, since the cross-sectional dimension of the video cable 22 is generally larger than that of the power cable 21, in the embodiment of the present application, the two power cables 21 are arranged at intervals in the circumferential direction of the video cable 22. Moreover, as the distance between the two power cables 21 decreases, the video cable 22 and the power cable 21 can be arranged more compactly, thereby reducing the size of the connection component 2, which is beneficial to the miniaturization of the video connection structure.

[0059] In some alternative embodiments of the present application, the connector 1 has a second direction Y, and the second direction Y is perpendicular to the first direction X; the first power cable port 111 and the second power cable port 112 are arranged at intervals along the second direction Y; in a plane perpendicular to the second direction Y along the second direction Y, a part of the first power cable port 111 overlaps with the second power cable port 112.

[0060] In the embodiment of the present application, since in a plane perpendicular to the second direction Y along the second direction Y, a part of the first power cable port 111 overlaps with the second power cable port 112, that is, the first power cable port 111 and the second power cable port 112 are arranged in a staggered manner in the first direction X. In this way, when the first cross-section of the video cable port 12 is circular, by arranging the two power cable ports 11 in a staggered manner in the first direction X, that is, moving the first power cable port 111 upward (i.e., in the first direction X towards the direction close to the video cable port 12), the space around the video cable port 12 can be fully utilized, thereby reducing the size of the connector 1, which is beneficial to the miniaturization of the video connection structure.

[0061] In some alternative embodiments of the present application, as Figures 1 to 2 shown, the connector 1 has a second direction Y, and the second direction Y is perpendicular to the first direction X; the connector 1 is provided with an anti-fooling groove 13, and the anti-fooling groove 13 is arranged on one or both sides of the power cable port 11 along the second direction Y.

[0062] In the embodiment of the present application, by providing the anti-fooling groove 13, the video connection structure can be connected to an external display device or other equipment safely, quickly, and accurately, thereby effectively protecting the safety of the equipment and the staff.

[0063] It should be noted that since the anti-fooling groove 13 is provided on the peripheral wall of the connector 1, the setting of the anti-fooling groove 13 needs to avoid the power cord port 11 and the video line port 12, and sufficient spacing should be left between the power cord port 11, the video line port 12 and the anti-fooling groove 13 so that the power cord port 11 and the video line port 12 have sufficient structural strength. In addition, the display device or other devices usually have anti-fooling protrusions provided at the corresponding positions of the anti-fooling groove 13. Through the cooperation of the anti-fooling protrusions and the anti-fooling groove 13, reliable connection between the video connection structure and the external display device or other devices can be achieved. In addition, the drawings of the embodiments of the present application only show the case where the anti-fooling grooves 13 are provided on both sides of the power cord port 11 along the second direction Y. In actual applications, those skilled in the art can also provide the anti-fooling groove 13 on only one side of the power cord port 11 along the second direction Y.

[0064] In some alternative embodiments of the present application, as Figure 1 , Figure 4 and Figure 5 shown, the video connection structure is further provided with a pressing member 14. The pressing member 14 is connected to the peripheral wall of the connector 1 and forms a pressing space between the pressing member 14 and the peripheral wall of the connector 1. Among them, a limiting protrusion 141 is provided on the side of the pressing member 14 facing away from the pressing space, and the limiting protrusion 141 is used to limit the connector 1.

[0065] In actual applications, when the video connection structure is connected to an external display device or other devices, due to the provision of the limiting protrusion 141, the limiting protrusion 141 can limit the connector 1, which can effectively prevent the video connection structure from detaching from the display device or other devices when being pulled by an external force, that is, the connection reliability between the video connection structure and the display device or other devices can be improved. When the video connection structure needs to be disconnected from an external display device or other devices, by pressing the pressing member 14, the pressing member 14 deforms in the direction close to the connector 1, thereby driving the limiting protrusion 141 to move in the direction close to the connector 1, so that the limitation on the connector 1 can be released, and the video connection structure can be smoothly disconnected from the display device or other devices.

[0066] It should be noted that in order to further reduce the size of the video connection structure, a relief space is provided at at least part of the peripheral wall of the connector 1. Specifically, the relief space is provided on the side of the peripheral wall of the connector 1 away from the video line port 12, and the pressing member 14 is arranged in the relief space. Compared with directly arranging the pressing member 14 on the peripheral wall of the connector 1, this can further reduce the size of the video connection structure and is beneficial to the miniaturization of the video connection structure. In addition, the display device or other devices usually have a protrusion or a recess provided at the corresponding position of the limiting protrusion 141. Through the cooperation of the limiting protrusion 141 and the protrusion or the recess, the video connection structure and the display device or other devices can be reliably connected together.

[0067] After measurement, the radius of the video connection structure in the embodiment of the present application can be reduced to 3.5 mm, that is, the size of the video connection structure is small and can be widely applied to narrow spaces.

[0068] In summary, the video connection structure provided by the embodiment of the present application has at least the following advantages:

[0069] In the embodiment of the present application, since the power line and the video line are arranged in the protective shell, and the power line, the video line and the protective shell are integrally injection-molded structures, an integrated connection component can be formed. In this way, during the installation process of the display device, since the connection component of the video connection structure is integrated, the problem of wire harness entanglement will not occur, which is beneficial to improving the convenience of installation and maintenance of the display device. In addition, integrally injection-molding the power line, the video line and the protective shell can also improve the overall structural strength of the connection component, which is beneficial to improving the service life of the connection component.

[0070] The embodiment of the present application also provides a sun visor display system, including: a sun visor, a display device, and the video connection structure according to any one of the above embodiments; the sun visor includes a plate body and a rotating shaft connected to each other, and the rotating shaft is used for rotatably connecting to a vehicle; the display device is arranged on the plate body; the video connection structure is arranged in the rotating shaft and is electrically connected to the display device.

[0071] In practical applications, the rotating shaft of the sun visor is generally cylindrical, and its radius is about 4.1 mm. Since the radius of the video connection structure is 3.5 mm, the video connection structure can be arranged in the rotating shaft without increasing the radius of the rotating shaft, thereby avoiding the exposure of the video connection structure and being beneficial to improving the aesthetic degree of the sun visor.

[0072] It should be noted that in the embodiment of the present application, the structure of the video connection structure is the same as that of the video connection structure in any one of the above embodiments, and its beneficial effects are also similar, which will not be elaborated here. In addition, the display device in the embodiment of the present application includes, but is not limited to, a waveguide imaging structure.

[0073] The embodiment of the present application also provides a vehicle, including the above sun visor display system.

[0074] It should be noted that in the embodiment of the present application, the structure of the sun visor display system is the same as that of the sun visor display system in any one of the above embodiments, and its beneficial effects are also similar, which will not be elaborated here.
