Description

Technical Field

[0001] This utility model relates to the field of USB data acquisition technology, specifically a USB audio and video data acquisition device. Background Technology

[0002] With the rise of live streaming and drone photography, more and more users need to transmit high-definition audio and video signals from devices such as cameras and game consoles to computers for real-time editing and streaming. During meetings and training sessions, connecting electronic whiteboards, professional cameras, and other devices via HDMI output interfaces and transmitting the video to a computer in real time via USB facilitates recording meeting or course content.

[0003] HDMI, as a multimedia audio and video interface, has been widely used and popularized. USB interfaces, with their broad compatibility and high-speed data transfer capabilities, have become an important bridge connecting computers and various peripherals. The USB 3.0 standard has significantly improved data transfer speeds, further meeting the needs of high-definition audio and video signal transmission.

[0004] Furthermore, continuous advancements in audio and video processing technology enable the acquisition of clear, colorful image data, which, after processing, is re-encoded according to UVC and UAC protocols and transmitted via USB. A USB high-definition video capture device is a high-definition multimedia acquisition device that can directly connect to devices equipped with HDMI output interfaces, such as high-definition cameras, surveillance equipment, and electronic whiteboards. The captured high-definition digital information is processed, encoded according to UVC and UAC standards, and then transmitted via USB to a computer, tablet, mobile phone, or device with recording software installed for recording, editing, and subsequent sharing or playback.

[0005] This USB high-definition video capture device can capture high-definition information of 4K and below and transmit it to computers, mobile phones, tablets and other devices via USB 3.0 or USB 2.0 specifications.

[0006] The USB high-definition video capture device features an HDMI Type-A male input, allowing direct connection to HDMI high-definition capture devices. The output end is equipped with a USB Type-A or Type-C male connector, enabling direct connection to computers or tablets without any adapters, connectors, or other accessories. Customized interfaces for specific devices can also be used for the output end, ensuring convenient and reliable connection. However, existing USB audio and video data capture devices have some drawbacks. For example, they lack cable management functionality, resulting in the cables dragging on the ground during use. This not only poses a safety hazard but also easily accumulates dust. Furthermore, the cables tend to become tangled and knotted during transport, and the capture device itself cannot be securely fixed in place. Therefore, we propose a new USB audio and video data capture device. Utility Model Content

[0023] 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.

[0024] Example 1:

[0025] Please see Figure 1-3 This utility model provides a technical solution: a USB audio and video data acquisition device, including an acquisition device body 1, a USB interface output terminal 3, and an HDMI interface input terminal 5;

[0026] A left data cable 2 is provided on the left side of the main body 1 of the collector, and a USB interface output terminal 3 is provided on the left side of the left data cable 2. A right data cable 4 is provided on the right side of the main body 1 of the collector, and an HDMI interface input terminal 5 is provided on the right side of the right data cable 4. The above contents are all common existing technologies in this field, so they will not be described in detail in this article.

[0027] The collector body 1 has a column 6 at the center of the left and right sides of its bottom. Each column 6 has a limiting disc 7 at its bottom. During use, the left data cable 2 and right data cable 4 can be wound up and placed on the corresponding column 6. The lengths of the left and right data cables 2 and 4 can be adjusted according to usage requirements. The limiting disc 7 prevents the cable from falling off. A rubber suction cup 8 is located at the center of the bottom of each limiting disc 7, which secures the limiting disc 7 and, in turn, the column 6, fixes the collector body 1. The front and rear ends of the collector body 1 have mounting slots 9 in the middle. A magnet 10 is installed inside each mounting slot 9. A matching magnet 11 is installed on the top of the USB output port 3 and the top of the HDMI input port 5. The neutral pole (N) of the magnet 10 is located at the end furthest from the collector body 1. The S-level is located at the end away from the USB interface output terminal 3 and the HDMI interface input terminal 5. When carrying it, the left data cable 2 and the right data cable 4 are first wound up and placed on the corresponding posts 6. Then, the USB interface output terminal 3 and the HDMI interface input terminal 5 can be attached to the magnets 10 on the front and rear ends of the collector body 1 by magnet 2 11. This makes it easy to carry and avoids mess.

[0028] Preferably, each of the columns 6 has an external threaded connecting block at the top center, and each of the left and right sides of the bottom of the collector body 1 has an internal threaded hole that matches the external threaded connecting block. The columns 6 are movably installed at the bottom of the collector body 1 through the matching external threaded connecting block and internal threaded hole. The cooperation between the external threaded connecting block and the internal threaded hole can achieve the effect of movably installing and disassembling the columns 6, so that they can be removed from the bottom left of the collector body 1 when not in use.

[0029] Preferably, the column 6 and the limiting disc 7 at the same position are integrally formed. The integrally formed structure has strong stability, is not easy to break and has a long service life. The limiting disc 7 is set in parallel with the collector body 1.

[0030] Preferably, the outer diameter of the limiting disc 7 is smaller than the length of the collector body 1 from the inside to the outside. This setting can avoid the limiting disc 7 being too large, thus affecting the overall use effect. A nameplate is set at the top center of the collector body 1, and the nameplate records the data information of the collector body 1.

[0031] Example 2:

[0032] Reference Figure 1-3This embodiment differs from the first embodiment in that: the outer wall of magnet 10 is fixedly bonded to the inner wall of the mounting groove 9. By bonding, magnet 10 can be stably installed in the mounting groove 9. The end of magnet 10 away from the mounting groove 9 is set on the same horizontal plane as the front and rear ends of the collector body 1. This setting can prevent magnet 10 from protruding, thus avoiding wear and damage during use. The surface of the column 6 is provided with anti-slip texture from top to bottom. The anti-slip texture can increase the friction, so that when the left data cable 2 and the right data cable 4 are rolled up on the surface, the phenomenon of falling downward is reduced. The included angle between the column 6 and the collector body 1 is set to 90 degrees. This setting can increase the structural stability between the column 6 and the collector body 1.

[0033] All electrical appliances mentioned in this article are connected to an external power source via wires.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
