[0024] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figure 1-Figure 8 As shown:

[0026] The present embodiment provides a new energy charging pile, including a charging pile body 1, a socket 2 is provided on the side of the charging pile body 1, a charging assembly is provided in the socket 2, a controller 3, an electric cylinder 4 and a sensor are provided in the charging pile body 1, the electric cylinder 4 is connected to the controller 3, the charging assembly includes a first plug 5 and a second plug 6, the first plug 5 is located outside the second plug 6, an actuating rod of the electric cylinder 4 is connected to the first plug 5, and the electric cylinder 4 can drive the first plug 5 and the second plug 6 to be plugged in and separated when energized, a charging line is connected to the first plug 5 and extends to the outside of the charging pile body 1, a heat dissipation hole 8 is opened between the first plug 5 and the second plug 6, the outside of the heat dissipation hole 8 is communicated with the socket 2, and the inside is communicated with the charging pile body 1, the heat dissipation hole 8 is closed when the first plug 5 and the second plug 6 are plugged in, and opened when the first plug 5 and the second plug 6 are separated.

[0027] A first limiting plate 9 and a second limiting plate 10 are fixed in the socket 2, and a fixing hole 26 is opened on the first limiting plate 9 and the second limiting plate 10. The first plug 5 slides in the fixing hole 26 of the first limiting plate 9, and the second plug 6 is fixed in the fixing hole 26 of the second limiting plate 10. The first plug 5 can move linearly relative to the second plug 6 on the first limiting plate 9, which is equivalent to the first plug 5 being able to be plugged in and out relative to the second plug 6. A terminal 11 is provided in the second plug 6, and the inner end of the terminal 11 extends into the charging pile body 1 to be connected to the circuit, and the outer end of the terminal 11 extends into the socket 2 The inner end of the first plug 5 is provided with a first electrical interface 12 connected to the terminal 11, and the outer end of the first plug 5 is provided with a second electrical interface 13 connected to the charging line interface. The first plug 5 is connected with a pull rod 7, and the inner end of the pull rod 7 passes through the second plug 6 and enters the charging pile body 1 to connect to the action rod of the electric cylinder 4. When charging, the action rod of the electric cylinder 4 extends and drives the first plug 5 to move inward through the pull rod 7 and plugs into the second plug 6; on the contrary, when not charging, the action rod of the electric cylinder 4 retracts and pushes the first plug 5 to move outward through the pull rod 7 and separates from the second plug 6. The sensor includes a smoke sensor, a temperature sensor, and a rain weather sensor, wherein the rain sensor is arranged in the socket 2 and outside the first plug 5.

[0028] A first sealing ring 15 is fixed to the inner end of the protrusion 14 , and a second sealing ring 16 is fixed to the outer end of the first limiting plate 9 . When the first plug 5 is plugged into the second plug 6 , the first sealing ring 15 and the second sealing ring 16 are in close contact, and the heat dissipation hole 8 also passes through the first sealing ring 15 .

[0029] Working principle and technical effect: When in use, one end of the charging cable (not shown in the prior art figure) is connected to the first plug 5 through the second electrical interface 13, and the other end of the charging head is plugged into the new energy vehicle. At this time, the controller 3 gives a command to the electric cylinder 4, and the action rod of the electric cylinder 4 extends outward. At the same time, the action rod drives the pull rod 7, and the pull rod 7 drags the first plug 5 inward, so that the first electrical interface 12 on the first plug 5 is connected to the terminal 11 on the second plug 6 (that is, the first plug 5 is plugged into the second plug 6 at this time) (when charging is in progress) Figure 5 As shown in the figure), the charging line charges the new energy vehicle through the charging head at the other end. If there is a sudden line fault during the charging process, the charging pile body 1 is equipped with automatic protection devices, such as fuses, AC contactors and main switches, which will cut off the circuit, stop charging, and automatically protect the circuit. In addition, the present invention also makes the charging function have double protection, which is reflected as follows: when the above factors occur, the circuit or electrical components will release heat or smoke, and the heat or smoke will be released into the charging pile body 1, which will be sensed by the sensor and fed back to the controller 3. The controller 3 controls the action rod of the electric cylinder 4 to retreat in the opposite direction, and the action rod drags the pull rod 7 in the opposite direction. The pull rod 7 pushes the first plug 5 in the opposite direction, so that the first plug 5 and the second plug 6 are pressed Figure 3 The wiring post 11 and the first electrical interface 12 are quickly separated as shown. Since the outer end of the first plug 5 is connected to the charging cable through the second electrical interface 13, and the other end of the charging cable is plugged into the new energy vehicle, the first plug 5 and the second plug 6 are automatically and mechanically separated in the above manner, which is equivalent to cutting off the power of the charging cable. At the same time, the charging cable is remotely separated from the circuit in the charging pile body 1. Even if the second plug 6 is still charged or hot, it will not affect the first plug 5, let alone the charging cable. At the same time, the above-mentioned protection element in the charging pile body 1 will also cut off the power supply, and mechanically move the first plug 5 away from the second plug 6 quickly, thereby cutting off the possibility of risk factors being transmitted to the new energy vehicle, and achieving double protection during the charging process.

[0030] During the charging process, since the first plug 5 is plugged into the second plug 6, the raised portion 14 on the outer end of the first plug 5 will use the first sealing ring 15 on the inner end surface to connect with the second sealing ring 16 on the outer end surface of the first limiting plate 9 to form a seal. At this time, the heat dissipation hole 8 that passes through the first sealing ring 15, the first limiting plate 9 and the second limiting plate 10 will be covered to prevent rainwater from entering during charging. When not charging and performing the above-mentioned mechanical protection, since the first plug 5 is separated outward from the second plug 6, the raised portion 14 separates with the first sealing ring 15 on the inner end surface from the second sealing ring 16 on the outer end surface of the first limiting plate 9, and the heat dissipation hole 8 is opened. The outer end contour of the raised portion 14 is smaller than the inner cavity contour of the socket 2, and the external gas enters the socket 2, and enters the heat dissipation hole 8 from the socket 2. The innermost part of the heat dissipation hole 8 is connected with the inner cavity of the charging pile body 1 to achieve heat exchange. It is well known that even if the charging pile body 1 is in a non-charging state, some of its internal components are normally energized, so that heat dissipation can be achieved and safety hazards can be reduced. Of course, on rainy days, the rain sensor in the socket 2 will receive a signal, allowing the first plug 5 to be quickly plugged into the second plug 6. Since there may not be a new energy vehicle charging at this time, even if the first plug 5 is plugged into the second plug 6, no loss will occur. However, at this time, the protrusion 14 will follow the plugging action of the first plug 5 and dock with the second sealing ring 16 on the outer end surface of the first limiting plate 9 to block the heat dissipation hole 8 to prevent water from entering. There are multiple heat dissipation holes 8. If the heat dissipation holes 8 are arranged in a ring array, they all pass through the first sealing ring 15, the first limiting plate 9 and the second limiting plate 10 in sequence, which improves the heat dissipation efficiency when the charging pile body 1 dissipates heat.

[0031] In another embodiment, if Figure 2 , Figure 4 as well as Figure 6 As shown, a compartment 17 is provided in the charging pile body 1, the top of the compartment 17 is communicated with the socket 2, and the socket 2 is located on the upper side of the compartment 17, and a wiring hole 18, a guide hole 19 and a connection hole 20 are provided on the compartment 17, the wiring hole 18 is close to the terminal 11, the pull rod 7 enters the compartment 17 through the guide hole 19 and is connected to the first plug 5, the bottom side of the compartment 17 is close to the bottom of the charging pile body 1, and the connection hole 20 is provided on the bottom side of the compartment 17, and the compartment 17 and the charging pile body 1 are gas-connected through the connection hole 20. The charging pile body 1 is filled with an air duct 21, and the top of the air duct 21 sequentially passes through all the wiring boards 24 in the charging pile body 1, and the wiring boards 24 are provided with heat dissipation grooves 25. The bottom end of the air duct 21 is connected to the connection hole 20. The air duct 21 is provided with multiple branch pipes 22 connected to the wiring parts in the charging pile body 1. At least one branch pipe 22 leads to the outside of the charging pile body 1. A fan 23 is fixed in the charging pile body 1, and the fan 23 is connected to the air duct 21. The connection method of the air duct 21, the branch pipe 22 and the pipe opening of the fan 23 is the existing technology and will not be repeated.

[0032] In this embodiment, it is well known that in most cases, an exhaust system (such as a fan, etc.) is set in the charging pile body 1, and a ventilation pipe or air duct is set to facilitate the heat in the charging pile body 1 to be released outward. In combination with this point, the present invention improves the air duct 21. First, multiple branch pipes 22 are set on the pipeline according to the distribution of components, and at least one branch pipe 22 is connected to the outside of the charging pile body 1. Whether charging or not charging, some branch pipes 22 are used to collect heat from the charging pile body 1, and then the heat is discharged to the outside of the charging pile body 1 through one of the branch pipes 22. The end of the air duct 21 also discharges the heat into the compartment 17, and the heat is discharged into the socket 2 through the heat dissipation hole 8, and then discharged outward from the socket 2. At the same time, when not charging or mechanical protection (when the first plug 5 is separated from the second plug 6), the heat still released by the circuit to the second plug 6 is discharged outward. Further reduce safety hazards.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures.
