Description

Technical Field

[0001] The utility model relates to the field of automotive electronic equipment, in particular to a vehicle-mounted multimedia vehicle machine. Background Art

[0002] In-car multimedia systems typically refer to electronic devices installed inside a car, integrating multiple functions, including audio playback, navigation, Bluetooth phone calls, and video playback. Their primary purpose is to enhance the entertainment and convenience of driving and vehicle use. They can play music, radio, videos, and more, enriching in-car entertainment and making long drives more enjoyable. Modern systems often support mobile phone connectivity (such as Apple CarPlay or Android Auto), allowing users to project phone functions onto the system for convenient access to commonly used apps.

[0003] Vehicle-mounted computer is generally directly connected to the vehicle power supply, but the vehicle power supply is unstable, which may sometimes cause damage to the computer or the connected transformer, causing the computer to malfunction. In addition, since the computer and transformer mostly use non-standard parts, repair and maintenance are relatively difficult.

[0004] When using a digital camera to take photos and record videos while traveling, you often encounter a troublesome problem. Most existing cameras use CF memory cards. CF memory cards have a long history, large storage capacity, low cost, and good compatibility. They were launched by a certain alliance in 1994. Almost all camera manufacturers on the market use CF cards. However, when you need to view the photos stored in the camera, you can only use the camera or use a complicated and bulky CF card reader or connection converter to connect it to a PC device for viewing. Using the camera to view will consume the camera's battery and affect its use. When traveling, it is inconvenient to carry a computer. Some portable laptops have outdated interfaces and low transmission rates, which makes the user experience very poor. Utility Model Content
