Embodiment 1

[0021] refer to Figure 1-3 , an anti-fatigue power connection structure for a lifting charging pile, including a foundation 1 and a charging pile body 4, a storage tank 2 is opened in the foundation 1, and a load-bearing plate 3 for placing the charging pile body 4 is sealed and slidably connected in the storage groove 2 , a drive device is provided between the load-bearing plate 3 and the storage tank 2, the drive device is a telescopic cylinder, and the telescopic cylinder is installed on the inner bottom wall of the storage tank 2, and the output end of the telescopic cylinder is fixedly connected with the lower end surface of the load-bearing plate 3, and the load-bearing The side wall of the plate 3 is embedded with a second conductive block 12, and the second conductive block 12 is electrically connected with a power-taking terminal 13, through which power is supplied to the external new energy vehicle. The second permanent magnet block 14 corresponding to the block 12;...

Embodiment 2

[0027] refer to Figure 4 , the difference between this implementation and Embodiment 1 is that: the groove wall of the receiving groove 2 is symmetrically provided with a limit groove corresponding to the placement groove 6, and the two limit grooves are respectively located on both sides of the placement groove 6, each limit The limit blocks 15 are slidably connected in the slots, and the ends of the plurality of limit blocks 15 away from the limit slots are fixedly connected with a baffle plate 16 , and the baffle plate 16 is sealingly and slidingly connected with the groove wall of the storage tank 2 .

[0028] In this embodiment, its functional principle can be explained through the following operation mode: when the charging pile body 4 is stored in the storage tank 2, under the action of gravity of the baffle plate 16 itself, the baffle plate 16 will block the notch of the placement slot 6, Thereby can prevent the outside impurity from entering into the placement groove...

Abstract

The invention discloses an anti-fatigue power connection structure for a lifting type charging pile. The anti-fatigue electric power connection structure comprises a foundation and a charging pile body, a storage groove is formed in the foundation, a bearing plate used for containing the charging pile body is connected into the storage groove in a sealed and sliding mode, and a driving device is arranged between the bearing plate and the storage groove; and a second conductive block is embedded in the side wall of the bearing plate, the second conductive block is electrically connected with apower taking terminal, and the bearing plate is provided with a second permanent magnet block corresponding to the second conductive block. According to the invention, by means of magnetic attractionof the first permanent magnet block and the second permanent magnet block, when the charging pile body is lifted to the storage groove, the first conductive block abuts against the second conductive block, a circuit is connected through conductive liquid, a power line is not needed, and therefore abrasion of the power line can be avoided, and the service life of the anti-fatigue power connection structure is prolonged; and compared with a power line, the anti-fatigue power connection structure is much convenient on the aspect of replacement of the conductive liquid.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an anti-fatigue power connection structure for a lifting charging pile. Background technique [0002] Charging pile is a kind of equipment for charging new energy vehicles. Nowadays, many residential areas or charging stations adopt lifting charging piles. When not in use, the charging piles are stored underground. The use space can also protect the charging pile. [0003] However, in actual use, the charging pile frequently moves up and down, the connecting wire of the charging pile needs to be rewound and unwound reciprocally, and the power cord is pulled and bent back and forth, which greatly reduces the service life of its protective layer. The existence of the power cord has poor heat dissipation. After long-term use, the high temperature of the power cord will not only affect the charging efficiency of the charging pile, but even cause fire and short circuit in...
