Title:
ELECTRIC CONNECTION APPARATUS, EMERGENCY POWER SUPPLY, AND VEHICLE-MOUNTED ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/077682
Kind Code:
A1
Abstract:
An electric connection apparatus, an emergency power supply (100), and a vehicle-mounted electric device (200). The emergency power supply (100) is electrically connected to the vehicle-mounted electric device (200) by means of the electric connection apparatus. Spherical protrusions (221) and spherical slots (121) are kept in a matching state by means of magnetic attraction effect of first magnets (130) and a matching member (230), such that first conductive members (120) are electrically connected to second conductive members (220). The first conductive members (120) are in close contact with the second conductive members (220) by means of magnetic force, and thus problems such as elastic fatigue are avoided. Moreover, the spherical protrusions (221) are in spherical contact with inner walls of the spherical slots (121), such that the contact area is large. In addition, even if the positions of the first conductive members (120) and the second conductive members (220) deflect due to violent vibration in a specific application scene, the area of contact between the spherical protrusions (221) and the spherical slots (121) is not obviously reduced, such that reliable contact is ensured. Therefore, said electric connection apparatus allows for remarkably improving the reliability of the electric connection between the emergency power supply (100) and the vehicle-mounted electric device (200).
