Description

Technical Field

[0001] The utility model relates to the technical field of charging interfaces, and in particular to a magnetic bracket, an adapter assembly and a charging assembly. Background Art

[0002] At present, there are various electric vehicle charging interfaces around the world, including GBT charging interface, CHAdeMO fast charging interface, Combo charging interface, Mennekes fast charging interface, standard AC charging interface Type 1 and Type 2, etc.

[0003] Among them, there are two types of gun line charging interfaces in some areas of North America: NACS charging interface and CCS1 charging interface. The former is the Tesla charging interface standard, and the latter is the North American charging interface standard. Generally, commercial charging piles are only equipped with one charging interface. If the charging gun itself is equipped with a CCS1 charging interface, it is necessary to connect the CCS1 ToNACS adapter (hereinafter referred to as the NACS adapter) to charge Tesla vehicles and other vehicles that require a NACS charging interface. Therefore, the existing NACS adapter needs to be carried by the owner. If the owner forgets to bring it or the adapter fails, charging will not be possible on the CCS1 charging pile.

[0004] Currently, there are two solutions:

[0005] 1. Double-headed gun solution, that is, one gun line is equipped with two charging ports: CCS1 charging port and NACS charging port. However, if all existing single-headed guns are upgraded to double-headed guns, the cost will increase significantly.

[0006] 2. Disassembly and replacement solution: that is, the existing charging pile with CCS1 charging interface is equipped with NACS adapter. Currently, the NACS adapter is generally pulled on the CCS1 gun line with a wire rope. However, the problem that will arise is that if the owner does not need to use the NACS adapter, the NACS adapter is in a suspended and dangling state. During the process of plugging and unplugging the charging gun, the NACS adapter will be at risk of scratching or hitting the vehicle.

[0007] Based on the above solutions, a new solution is to add a magnet to the adapter to adsorb it to the charging gun, but the charging gun itself cannot guarantee that the magnet of the adapter can be adsorbed. Therefore, there is a lack of technology that can allow the magnetic adapter to be quickly and accurately adsorbed to the charging gun. Utility Model Content
