Embodiment 1

[0038] Such as Figure 1-6 As shown, this embodiment provides a large current channel selection PDU system, including a PDU robot module 1 and an external channel 5, the external channel 5 is arranged in an array on the periphery of the PDU robot module 1, and the PDU robot module 1 moves to the station , the electrode unit 12 in the PDU robot module 1 protrudes and contacts the external channel 5 to form an electrical connection.

[0039] PDU robot module 1 comprises mobile carrier 11, electrode unit 12 and driver 14, and electrode unit 12 comprises input electrode 121 and output electrode 122, is electrically connected between input electrode 121 and output electrode 122, and input electrode 121 and output electrode 122 are driven Driven by the driving element 14, it protrudes from the mobile carrier 11 to connect the external circuit; when the input electrode 121 and the output electrode 122 are retracted into the mobile carrier 11 driven by the driving element 14, the exte...

Embodiment 2

[0051] Such as Figure 7 As shown, the present embodiment is basically the same as the first embodiment, the only difference lies in the structure of the transmission assembly 15 . In this embodiment, the transmission assembly 15 includes a screw rod 151 and a nut 152. There is one screw rod 151 and two nuts 152. Both ends of the screw rod 151 are rotatably mounted on the side plate 112, and the two nuts 152 are symmetrical. It is arranged on the screw rod 151, and the two nuts 152 and the two ends of the screw rod 151 are anti-threaded, so that the two nuts 152 drive the two brackets 13 to move toward each other or backwards synchronously.

[0052] Further, a first helical gear 153 is connected to the driving end of the driving member 14 , and a second helical gear 154 is provided on the screw rod 151 , and the first helical gear 153 and the second helical gear 154 mesh.

Embodiment 3

[0054] Such as Figure 8 As shown, this embodiment is basically the same as Embodiment 1, the only difference is that the transmission assembly 15 can be omitted in this embodiment, and the driving member 14 can be configured as a telescopic driving device. The driving part 14 includes a driving part 141 and a telescoping part 142. The driving part 141 and the telescopic part 142 are respectively fixedly connected with the two brackets 13, and the two brackets 13 are moved synchronously towards or away from each other through the expansion and contraction of the driving part 14 itself. The driver 14 can be optional but not limited to air cylinder, hydraulic cylinder, electric cylinder, frame type electromagnet.

Abstract

The invention relates to the field of charging, and in particular, relates to a high-current channel selector PDU system. The high-current channel selector PDU system comprises PDU robot modules and external channels; each PDU robot module comprises a moving carrier and an electrode unit arranged on the moving carrier, the moving carrier drives the electrode unit to move to a station, and the electrode unit stretches out and draws back to make contact with an external channel to form electric connection; the external channels are arranged outside the PDU robot modules, the external channels comprise at least two groups of input channels and / or output channels, the input channels and the PDU robot modules are arranged in a one-to-one correspondence mode, and the input channels and the output channels are arranged on the same side in a staggered array mode. The problems that in the prior art, a plurality of relays or a plurality of paths of relays are adopted for power distribution, fixed wiring is needed, circuits are complex, flexibility is poor, and heat productivity is high are solved.

Description

technical field [0001] The invention relates to the charging field, in particular to a large current channel selector PDU system. Background technique [0002] When using charging piles to charge electric vehicles, electric vehicles with different power requirements will be encountered. When a small electric vehicle requires low power, the charging pile will waste its own power supply capacity resources, or when a large electric vehicle needs more than the power supply capacity of a single charging pile itself, the charging time will be longer. [0003] In the existing flexible power distribution system of charging piles, the core unit PDU adopts a single relay / contactor to form an MxN array, or uses multiple fixed multi-contact relays / contactors, which are essentially a MxN relay group in array mode. The disadvantage of directly using the relay array is that the amount of relays is large, the cost is high, and MxN complex control circuits are required. This kind of soluti...
