Problems solved by technology

This distribution method technology is relatively mature, but due to its own circuit design, a large number of electronic switches are required to perform repeated on-off according to complex requirements, and the stability will also decrease.
On the other hand, a large number of electronic switches also directly increase the cost of equipment and later maintenance costs

Abstract

The invention provides a rotary connection unit, a connection channel selection device, and a charging device. The rotary connection unit includes: a base assembly, the base assembly includes a bottom plate, a side wall of the base, and a first contact group, and an incoming line is opened on the side wall of the base. mouth; upper cover assembly, the upper cover assembly includes an upper cover plate, an upper cover side wall, a second contact group and a retractable contact group, and the second contact group is respectively connected with the first contact group and the retractable contact group connection; the rotation mechanism, the rotation mechanism is arranged between the base assembly and the upper cover assembly, and is used to control the rotation of the upper cover assembly relative to the base assembly; In the cavity, the telescopic control mechanism is used to control the telescopic contact group to protrude from the side wall of the upper cover or retract into the side wall of the upper cover. The invention has simple structure and is easy to control, can improve the efficiency, flexibility and stability of the electrical connection between the power supply and power receiving devices, and can reduce the cost.

Description

technical field [0001] The invention relates to the technical field of charging devices, in particular to a rotary connection unit, a connection channel selection device and a charging device. Background technique [0002] As the country's support for the new energy field increases year by year, the popularity of electric vehicles is also increasing, and more and more charging equipment as electric vehicle charging and supplementary facilities appear in people's daily life. [0003] Existing charging equipment is mainly divided into AC piles and DC piles, among which DC piles can meet the urgent needs of emergency power replenishment for electric vehicles due to their relatively high power. However, in actual station use scenarios, it is rare that charging piles need to be fully loaded, and at the same time, short-term high power fluctuations will affect the power supply network. In order to avoid this situation, it is very important for the charging pile to intelligently a...
