Description

Technical Field

[0001] The utility model relates to the technical field of USB boxes, in particular to a USB box and a vehicle. Background Art

[0002] USB, a universal serial bus technology, has been widely adopted in consumer electronics. As vehicles become increasingly intelligent, more and more are being equipped with USB boxes, which provide the following functions: data reading, data recording, device charging, and device expansion. Data reading functions include reading audio and video files from removable media (such as USB flash drives); data recording functions include storing dashcam footage to removable media; device charging functions include charging mobile phones, and high-end models also offer fast charging capabilities; and device expansion functions include connecting other smart devices to the vehicle via the USB port.

[0003] Typically, USB boxes are mounted on the dashboard in the vehicle's cockpit for ease of use. However, these locations are susceptible to water and moisture intrusion, such as when a passenger accidentally spills or splashes water onto the USB port, or when water vapor condenses on the box's surface and flows into the device. Once water enters the box, it can cause irreversible damage to the circuit boards within, potentially damaging important data stored on removable storage media connected to the box. Furthermore, water can destabilize the box's electromagnetic compatibility (EMC) performance, interfering with wireless communications within the vehicle's cabin, such as Bluetooth, Wi-Fi, and antennas. Over time, this can shorten the box's lifespan. Utility Model Content
