Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, specifically to a converter cable with bidirectional fast charging function and video capture. Background Technology

[0002] In the current technological context, as a crucial bridge connecting multimedia devices and display terminals, the improvement of the functionality and performance of capture and projection cables has always been a focus of market attention. Traditional capture and projection cables mostly adopt a USB Type-C to HDMI + PD charging solution. While this design can achieve both video signal transmission and charging of the projection end, it is often limited by the technical architecture and cannot simultaneously meet the power supply requirements of the capture end.

[0003] With the widespread adoption of USB Type-C interfaces, more and more electronic devices are beginning to support data transfer and power supply via this interface. This not only provides users with a more convenient connection method but also drives the further development of capture and projection cable technology. In this market environment, users' requirements for capture and projection cables are no longer limited to basic video transmission and single-port charging functions; they expect innovative products that can simultaneously meet the charging needs of both the projection and capture ends. Utility Model Content

[0004] Therefore, the purpose of this application is to solve the technical problem that the existing data acquisition and projection cable cannot simultaneously meet the charging needs of both the projection end and the data acquisition end.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A converter cable with bidirectional fast charging and video capture functions includes a main body, a capture end, and a projection end. The main body includes a PCB board, and a USB-C power port is provided on one side of the PCB board in the width direction. The PCB board also has a video capture chip, a projection and fast charging integrated chip, and a power distribution IC chip. The projection and fast charging integrated chip is connected to the projection end and the video capture chip, respectively. The video capture chip is connected to the capture end. The power distribution IC chip is connected to both the video capture chip and the projection and fast charging integrated chip, respectively. The power distribution IC chip is also connected to the USB-C power port.

[0007] Preferably, the main body is cylindrical, and the main body also includes a housing, with the PCB board mounted inside the housing.

[0008] Preferably, the housing is provided with a plurality of heat dissipation holes, which are arranged along the length of the housing.

[0009] Preferably, the PCB board is connected to the acquisition end and the projection end via wires. There are two wires, which are located at both ends of the PCB board along its length and pass through the housing.

[0010] Preferably, the housing is provided with a reinforcing ring, which is integrally formed with the conductor, and the inner wall of the reinforcing ring abuts against the outer wall of the conductor.

[0011] Preferably, the video acquisition chip is further provided with a circuit protection IC chip, and the video acquisition chip is connected to the power distribution IC chip through the circuit protection IC chip.

[0012] Compared with the prior art, this application has the following beneficial effects:

[0013] 1. High-efficiency fast charging and multi-functional integration: This adapter cable integrates bidirectional fast charging and video capture functions. Through an intelligent power distribution IC chip, it can efficiently distribute the 100W power input from the USB-C power port to the projection end and the capture end, achieving a maximum fast charging of 60W for the projection end while ensuring the 30W fast charging requirement of the capture end. This satisfies the high energy consumption requirements of the device during projection while also taking into account the fast charging of the video capture device, greatly improving the efficiency and convenience of use.

[0014] 2. Enhanced Connection Stability and Durability: The reinforced ring design effectively strengthens the connection between the conductor and the housing, reducing the risk of conductor damage due to frequent plugging and unplugging or external forces, and improving the overall durability and lifespan of the adapter cable. This is especially important for users who frequently need to move the cable or use it in complex environments.

[0015] 3. Safety protection mechanism: The built-in circuit protection IC chip provides additional safety protection when charging the acquisition end, preventing damage to the video acquisition chip due to excessive current or unstable voltage. This ensures the safety of the conversion cable during high-speed data transmission and charging, and reduces the equipment failure rate.

[0016] 4. Wide compatibility and application scenarios: Thanks to the adoption of a standard USB C interface and advanced screen projection and fast charging two-in-one chip technology, this adapter cable is widely compatible with most smartphones, tablets, laptops and professional video capture equipment on the market. It is suitable for various scenarios such as conference presentations, online education, and outdoor live streaming, providing users with great flexibility and convenience.

[0017] 5. Simplify device connections and improve work efficiency: Traditional video casting and charging usually require multiple cables and adapters. This adapter cable integrates these two functions into one cable through an integrated design, which greatly simplifies the connection between devices, reduces cable clutter on the desktop or in the backpack, and improves work efficiency and user experience.
