Example 2

The present embodiment discloses a control method of a waterproof charging device for controlling the waterproof charging device described in embodiment 1.

The control method comprises the following steps:

step S1: when the accumulated water around the charging equipment rises, the floating ball 7 rises along with the water level, and when the accumulated water reaches the top end of the water collecting cavity 23, the pressure switch 9 is triggered, and the pressure switch 9 sends out an accumulated water level overrun signal;

step S2: the controller receives the water accumulation level overrun signal, cuts off the power of the charging socket 4 and switches into a waterproof bubble mode at the same time;

step S4: the waterproof baffle driving mechanism is started, and the waterproof baffle 12 ascends and shields the charging cavity 3;

step S5: the sealing mechanism is activated to waterproof seal the waterproof barrier 12.

Wherein, step S1 specifically further includes: step S10: when the floating ball 7 reaches the top end of the water collecting cavity 23, the floating ball 7 is abutted with the sealing sleeve 8, the sealing sleeve 8 is extruded and deformed under the action of the floating ball 7, and the deformed sealing sleeve 8 triggers the pressure switch 9.

The waterproof performance of the position of the pressure switch 9 can be obviously improved by arranging the sealing sleeve 8, and the waterproof performance of the charging equipment is further improved.

In one embodiment, the step S3 of "the charging plug ejecting mechanism is started, and ejecting the charging plug" specifically includes:

step S30: the electromagnetic suction device 11 is powered off, the reset elastic piece 22 performs reset motion, the magnetic suction plate 21 is pulled to the backboard where the charging socket 4 is located, the ejection column 211 moves into the charging channel, and the charging plug is ejected.

Alternatively, in another embodiment, the step S3 of "the charging plug ejecting mechanism is started, and ejecting the charging plug" specifically includes:

step S30': the electromagnetic suction device 11 is electrified, the magnetic suction plate 21 moves towards the electromagnetic suction device 11, the reset elastic piece 22 is stretched, the ejection column 211 moves towards the charging channel, and the charging plug is ejected.

One of the two steps can eject the charging plug in the charging socket 4, even if no charging plug exists in the charging socket 4 when waterlogging occurs, the operation of the charging plug ejecting mechanism does not influence the operation of the charging equipment in a waterproof mode.

Specifically, in this embodiment, after step S3, before step S4, the method further includes:

in step S31, the ejector mechanism is activated to eject the charging plug and the charging cord connected thereto from the area sealed by the waterproof barrier 12.

This arrangement further ensures that the flashing 12 can rise normally, completing the seal.

In one embodiment, the step S4 includes:

step S40: the driving device 10 is started to drive the gear 15 to rotate, the gear 15 drives the rack 16 to ascend, and the rack 16 drives the waterproof baffle 12 to ascend so as to shield the charging cavity 3.

Preferably, in step S40, further includes:

step S400: the toothed rack 16 is lifted up along a guide chute 18 by a guide slide 19.

This arrangement makes it possible to make the waterproof baffle 12 rise smoothly without occurrence of deviation.

As an embodiment of the present invention, the step S5 further includes:

step S50: the inflator 20 is activated to inflate the inner seal 13 and the outer seal 14 such that the first projection 134 and the second projection 144 respectively abut against both sides of the waterproof barrier 12 to form a waterproof seal of the waterproof barrier 12.

This arrangement can form a double waterproof seal on the inner and outer sides of the waterproof barrier 12, improving the effect of the charging device against blisters.

As an embodiment of the present invention, the control method further includes:

step S6: the remote communication controller sends signals to the cloud control platform, and the cloud control platform remotely controls the charging equipment to be powered off.

This setting can be when charging equipment is by the bubble with its complete outage, has avoided taking place the risk of electric leakage, has improved charging equipment's security when the waterlogging takes place.
