Description

Technical Field

[0001] This utility model belongs to the field of signal conversion technology, specifically relating to a Type-C video conversion device. Background Technology

[0002] Type-C video converters primarily refer to devices that convert video signals output from the USB Type-C interface on a device (such as a laptop, mobile phone, or tablet) into video interfaces commonly used by other monitors or projectors (such as HDMI, VGA, DisplayPort, DVI, etc.) for connection to various display devices. For example, a Type-C signal source can be converted into an HDMI signal by a module A chip and output to a display device, or an HDMI signal source can be converted into a Type-C signal by a module B chip and output to a display device.

[0003] However, existing Type-C video converter interface cables integrate functional circuits into the plugs at both ends, which causes high-frequency signals to have to travel back and forth through the entire cable, resulting in accumulated timing offsets. Secondly, because the interfaces at both ends are different, different interfaces need to be produced during manufacturing, resulting in a significant increase in production costs. Utility Model Content

[0016] 1. This utility model sets up a central control module between the interface modules, so that the functional modules in the interface body can be integrated into the central control module, so that high-frequency signals do not need to travel back and forth through the entire cable, thus reducing the accumulation of timing offset; secondly, by using a unified Type-C interface at both ends, not only can production costs be effectively saved, but also charging, data transmission and video output can be realized based on the full functionality of the Type-C interface;

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] This utility model relates to a Type-C video conversion device, such as... Figures 1-3 As shown, it includes a control unit 1 and an interface unit 2 electrically connected to both ends of the control unit 1.

[0031] The control unit 1 includes a central control module 11; the interface unit 2 includes an interface body 21 electrically connected to the central control module 11, and the functional modules within the interface body 21 are integrated on the central control module 11.

[0032] In this embodiment, the interface body 21 is a Type-C interface. By integrating the functional modules within the Type-C interface onto the central control module 11, high-frequency signals do not need to travel back and forth across the entire cable, thus reducing the accumulation of timing offset. It should be noted that the functional modules within the Type-C interface are a miniature circuit board, which includes an E-Marker chip module for storing and declaring cable capability parameters, a PD protocol controller module for real-time power supply negotiation, and a high-speed signal switching switch and a Type-C video conversion device module for dynamically switching the signal path of the Type-C interface. This is prior art and will not be elaborated upon here.

[0033] Furthermore, such as Figures 3-4 As shown, the interface unit 2 also includes a wiring 22 electrically connected to the interface body 21, and a connector 23 electrically connected to the end of the wiring 22 for electrical connection with the central control module 11. In this embodiment, the connector 23 is an SR connector. The SR connector can eliminate the stress generated by external forces during use of the wiring 22, thereby ensuring the stability and reliability of the electrical connection.

[0034] Furthermore, such as Figures 3-7 As shown, the control unit 1 also includes an outer housing 12 for housing the central control module 11, and plugs 13 that are sleeved on the wiring 22 and detachably connected to both ends of the housing 12. By using an aluminum housing 12 and plastic plugs 13, the central control module 11 can be enclosed to provide effective protection.

[0035] Specifically, the outer casing 12 includes a top wall 121 and a bottom wall 122 disposed opposite to each other, and a side wall 123 connected between the top wall 121 and the bottom wall 122 to form an enclosure, thereby forming a hollow cavity with both ends connected within the outer casing 12. This hollow cavity is used to install the central control module 11, such as... Figure 4 As shown;

[0036] Among them, such as Figures 5-6 As shown, concave grooves 1211 extending along their width direction are respectively provided on the inner walls of the top wall 121 and bottom wall 122 at both ends of the outer casing 12. The plug 13 is adapted to the end of the hollow cavity and is sleeved on the wiring 22 through the wire hole 133 provided thereon. It can be inserted into the end of the hollow cavity. A locking block 134 is provided opposite to the surface of the top wall 121 and bottom wall 122 of the outer casing 12, which is adapted to and engages with the groove 1211. When the plug 13 is inserted into the end of the hollow cavity, the locking block 134 can engage in the groove 1211, so that the plug 13 is connected to the end of the outer casing 12.

[0037] Additionally, on the inner side of at least one sidewall 123 of the outer casing 12, a limiting block 1231 extending along its length direction is also provided, such as... Figure 7 As shown, the plug 13 has opposing clamping blocks 132 on its inner surface relative to the end of the housing 12. During assembly, after the side edge of the central control module 11 is slidably inserted between the limiting blocks 1231, and then the plug 13 is installed on the end of the housing 12, the clamping blocks 132 can clamp the end edge of the central control module 11 to fix the entire central control module 11, thus achieving convenient assembly.

[0038] Example 2:

[0039] The only difference from the above embodiment 1 is that: the central control module 11 is also electrically connected to the function expansion module 15, and the surface of the housing 12 is provided with a through hole 14 that is adapted to and communicates with the function expansion module 15, so that the interface of the function expansion module 15 is exposed on the housing 12 for easy connection.

[0040] In this embodiment, the function expansion module 15 is a charging module, similar to the charging port of a mobile phone. The charging module is electrically connected to the function module in the Type-C interface on the central control module 11. It can simultaneously power devices connected to both ends of the Type-C interface that are not connected to a power source, or power one of the devices that can output power, and then power another device that needs to input power through the device, thereby improving the convenience of use.

[0041] The functional expansion module 15 includes, but is not limited to, a charging module, and may also be other types of interface modules, which will not be described in detail here.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
