[0018] The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0019] The utility model provides a safe quick-detachable electric vehicle charging pile, which is mainly composed of two parts: a charging pile body and a socket assembly.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, the overall structure of the charging pile is mainly composed of an aircraft plug mother seat 1, a charging pile body, an air switch box assembly 3, an air switch wiring harness 4, a gun head mount 5, and a socket wiring harness 7.

[0021] The charging pile body comprises a charging pile connection seat 2 , and the charging pile connection seat 2 is provided with an aviation plug male head 8 and an anti-theft lock 9 .

[0022] The socket assembly includes an aircraft socket mother seat 1, an air switch box assembly 3, an air switch wiring harness 4, a gun head mount 5, and a socket wiring harness 7.

[0023] The specific installation implementation is as follows:

[0024] First, install the socket assembly (aircraft socket mother seat 1, air switch box assembly 3, air switch wiring harness 4, gun head hanger 5, socket wiring harness 7) on the wall surface 6 of the distributed design (not limited to the wall);

[0025] The handheld charging pile body (with the aviation plug male head 8 and the anti-theft lock 9) is aligned with the aviation plug female seat 1 installed on the wall 6, and inserted into it. After docking, use the key to lock the anti-theft lock 9. At this time, the charging pile body has been installed in place;

[0026] When you need to disassemble the charging pile body and change to a different wall socket position, you only need to unlock the anti-theft lock with the key and unplug it directly from the aircraft socket. This makes it extremely convenient to quickly install and disassemble the charging pile body.

[0027] like Figure 3 As shown, when the charging pile body is not installed on the aircraft plug mother socket, the aircraft plug mother socket cannot be powered on and maintained by the circuit breaker. Only when the charging pile body is in the installed state can it be powered on and maintained by the circuit breaker; ensuring that the aviation plug will not be always energized when the socket is in the empty state; on the other hand, when the charging pile body is unplugged from the energized aircraft plug mother socket, the circuit breaker will automatically disconnect, so that no matter whether the charging pile body is in the installed state or the uninstalled state, the aviation socket is always guaranteed to be unpowered; thereby ensuring the safety of users' electricity use and greatly reducing the risk of accidental touch.

[0028] During installation, the charging pile body with the aviation male plug on the back cover is quickly plugged into the wall with the socket assembly. After the plug is in place, the charging pile body with the anti-theft lock is locked with a key. Before that, the aviation female socket on the wall is always in a power-off state through the air switch box assembly with a pressure loss release. The charging pile body assembly must be installed before power can be turned on to play a safety protection function. Figure 4 and Figure 5For example, the air switch box assembly mainly includes a pressure loss release DZ47SMSN connected in parallel between the external power supply system and the aviation socket motherboard (the Delixi series is selected here, and other brands can also be selected, such as Schneider MNs electronic pressure loss release; Chint MNs electromagnetic pressure loss release), a pair of auxiliary contact switches OF3, a leakage protection air switch DZ47SLe and a waterproof air switch box HT-5. Among them, the aviation socket motherboard is provided with a first terminal connected to one end of the pressure loss release, a second terminal connected to the neutral line of the external power supply system, a second terminal and a third terminal connected to the air switch; the other end of the pressure loss release is connected to the live line of the external power supply system. The auxiliary contact switch OF3 includes a normally open contact switch and a hand switch for testing.

[0029] When disassembling and transporting, you only need to use the anti-theft lock to manually unlock it, and you can quickly unplug the charging pile body from the wall-mounted aircraft socket. At the same time, during the unplugging process, the wall-mounted aircraft socket will automatically power off through the air switch box assembly with a pressure-loss release, thus achieving the safety anti-electric shock protection function of the socket being unpowered when there is no pile.

[0030] The above description is only a preferred specific implementation manner of the present utility model. It should be pointed out that the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present utility model can make equivalent substitutions or changes based on the technical scheme and utility model concept of the present utility model, which should be covered by the protection scope of the present utility model.
