Description

Technical Field

[0001] This invention relates to a charging stand, and more particularly to a charging stand that has both AC charging and DC charging functions. Background Technology

[0002] In existing technologies, to charge the battery packs of new energy electric vehicles, a charging socket suitable for mates with a charging gun needs to be installed on the vehicle. In existing technologies, a charging socket with both AC and DC charging functions typically includes a mounting bracket, a housing, AC power terminals, and DC power terminals. The mounting bracket is used to fix it to the vehicle body, for example, to a sheet metal part of the vehicle body. The housing is fixed to the mounting bracket. A first terminal hole for inserting the AC power terminals and a second terminal hole for inserting the DC power terminals are formed in the housing. In existing technologies, because the AC charging module and the DC charging module are integrated into the same housing, the DC charging module and the AC charging module cannot be replaced separately; both must be replaced simultaneously. This leads to inconvenience and high cost.

[0003] In existing technologies, increasing charging speed requires increasing the charging current, currently reaching 600A and potentially even 1000A in the future. When a large current flows through the power terminals inside the charging dock, it generates significant heat, causing a rapid rise in the temperature of the power terminals. If this temperature rise is not controlled in time, it can lead to safety accidents, such as burning out the charging dock or other electrical equipment. Currently, to control the temperature rise of the power terminals, a lead frame is typically installed in the charging dock housing, with a terminal temperature detection module integrated on the lead frame. However, in existing technologies, the lead frame is bulky and needs to be pre-installed in the charging dock housing, making it inconvenient to use. Furthermore, to facilitate the installation of the lead frame, the charging dock housing requires a split design. Existing charging dock housings typically consist of a main body and a rear cover assembled to the rear port of the main body, resulting in a complex structure and high cost.
