Implementation

[0019] like Figure 1-Figure 10 This embodiment discloses a fixed and mobile shared charging pile for new energy vehicles, including a charging gun 1, a lock control base 2, and an electric control box 3.

[0020] In this embodiment, the charging gun 1 includes a gun head 11, a cable 12, a plug 13, and a charging control module 14. The charging control module 14 includes a charging protocol module 141 and a Bluetooth communication module 142 that comply with the requirements of the Chinese national standard numbered GB / T 18487.1-2015 (hereinafter referred to as the "national standard"). The Bluetooth communication module is used to connect to the user's mobile phone via Bluetooth to achieve information interaction.

[0021] In this embodiment, the electric control box 3 includes a socket 31, a box door 32, a box door password lock 33, an air switch 34, and a leakage protection switch 35. The AC power supply is connected to the socket 31 via the air switch 34 and the leakage protection switch 35. The plug 13 is used to insert or unplug the socket 31 to achieve electrical connection or separation with the AC power supply, and provide a basic structure for realizing fixed and mobile sharing of charging piles.

[0022] In this embodiment, the lock control base 2 includes a main control module 21, an electric lock mechanism 22, a locking rod 23, a mechanical lock 24, a housing 25, a gun seat 26, and a mounting hole 27; the locking rod 23 includes a pin 231, a lock card 232, and a square hole 233; the main control module 21 is electrically connected to and controls the movement of the electric mechanism 22.

[0023] In this embodiment, the gun head 11 includes a buckle 111, a locking groove 112, and an unlocking button 113. The gun base 26 includes a slot 264 corresponding to the buckle 111. The locking groove 112 is located at a locking position above the buckle 111. The ejector pin 231 extends into the locking groove 112. Pressing the unlocking button 113 cannot move the buckle 111 up and out of the slot 264, that is, the gun head 11 is locked to the gun base 26.

[0024] In this embodiment, the electric locking mechanism 22 includes a DC motor and its reduction mechanism 221, a transmission shaft 222, a fork 223, and a fixing plate 224. One end of the fork 223 is connected to the transmission shaft 222, and the other end is inserted into the square hole 233. When the DC motor and its reduction mechanism 221 are connected to a forward or reverse current, the ejector pin 231 can be driven to extend into or out of the locking groove 112 of the gun head 11 to lock or unlock the gun head 11 and the gun seat 26.

[0025] In this embodiment, the mechanical lock 24 includes a movable lock frame 241; the movable lock frame 241 includes a lock pin 2411 and a baffle 2412; the lock pin 2411 can be unlocked by the mechanical lock 24 and rotated ( Figure 6 The locking card 232 is driven to pull the ejector pin 231 out of the locking groove 112 on the gun head 11, thereby mechanically unlocking the gun head 11 and the gun seat 26.

[0026] In this embodiment, the baffle 2412 is used to block or allow external tools to be inserted into the mounting hole 27 to remove the housing 25 according to the state of the mechanical lock 24. The baffle 2412 extends into the mounting hole 27 when the mechanical lock 24 is in a locked state, and blocks external screwdriver tools from entering, thereby achieving the purpose of anti-theft; when the mechanical lock 24 is unlocked and rotated to an unlocked state, the baffle 2412 follows the rotation and disengages from the mounting hole 27, and an external screwdriver tool can enter the mounting hole 27 to remove the housing 25.

[0027] In this embodiment, the gun base 26 includes a PE port socket 261, a CP port socket 262, and a CC port socket 263; the PE port socket 261 and the CP port socket 262 are connected to the main control module 21. Correspondingly, according to the national standard, the gun head 11 includes a PE pin 114, a CP pin 115, and a CC pin 116 that are electrically connected to the charging control module 14. When the gun head 11 is inserted into the gun base 26, the PE pin 114 is electrically connected to the PE port socket 261, and the CP pin 115 is electrically connected to the CP port socket 262, so that the main control module 21 obtains power from the charging control module 14. Based on the national standard, Figure 8 The R1 resistor 1415 is defined as having a resistance value of 1000 ohms, and the power output power of the power supply is limited and cannot meet the power requirement of the main control module 2. Therefore, the charging control module 14 in this embodiment includes a MOS tube switch 143 connected in parallel to both ends of the R1 resistor 1415. When the MOS tube switch 143 is turned on, the R1 resistor 1415 is short-circuited, and the main control module 21 can obtain a power supply with sufficient power through the CP port socket 262 and the PE port socket 261.

[0028] In this embodiment, the charging protocol module 141 includes a 12V power supply 1412, and the charging control module 14 includes a PWM adjustable power supply 144, a switch 145, and a first voltage detection module 146. The main control module 21 includes a second voltage detection module 211, and the second voltage detection module 211 is used to detect the PWM output duty cycle or voltage value of the CP port socket 112; the charging control module 14 sends a control instruction to the main control module 21 by adjusting the voltage value of the CP port socket 112. In other words, the second voltage detection module 211 is used to detect the control instruction sent by the charging control module 14, and the control instruction includes an unlock instruction. The charging control module 14 adjusts the voltage value by changing the duty cycle of the output voltage PWM. Under different PWM duty cycle outputs, the second voltage detection module 211 detects different voltage values, and determines the type of the control instruction according to the voltage value.

[0029] In this embodiment, the main control module 21 includes a third voltage detection module 212 and a voltage-dividing resistor 213; one end of the voltage-dividing resistor 213 is electrically connected to the CC port socket 263, and the CP port socket 262 is electrically connected to a diode and then connected to the other end of the voltage-dividing resistor 213. According to the national standard, the charging control module 14 includes an RC resistor 1416 and an R4 resistor 1417 and a micro switch 1418 arranged inside the gun head 11. When the gun head 11 is fully inserted into the gun seat 26, the micro switch 1418 is closed, and the R4 resistor 1417 is short-circuited, thereby causing the third voltage detection module 211 or the first voltage detection module 146 to change the voltage value detected by the detection point of the CC port socket 263. The main control module 21 or the charging control module 14 can determine the state of the charging gun being inserted into the gun seat 26 according to the change in the voltage value, and the state includes separation, incomplete insertion, and complete insertion.

[0030] In this embodiment, the locking process includes: After the user finishes charging the car, the gun head 11 is completely inserted into the gun seat 26. The 12V power supply 1412 outputs voltage through the R1 resistor 1415. The first voltage detection module 146 detects the agreed voltage value at the detection point, and the charging control module 14 confirms that the gun head 11 has been completely inserted into the gun seat 26. Then the charging control module 14 turns on the MOS tube switch 143, and the main control module 21 obtains a power supply with sufficient power to start working. After the main control module 21 detects that the charging gun is fully inserted through the third voltage detection module 212, it controls the electric lock mechanism 22 to link the lock rod 23 to extend the ejector 231 into the lock slot 112, and the gun head 11 is locked in the gun seat 26 and cannot be pulled out. That is, the technical effect of automatic locking when inserted is achieved. After locking, the charging control module 14 can control the charging protocol module 141 to be in an unavailable state. According to the national standard, if the CP port voltage output is stopped or the protocol signal sent by the car is not responded, then even if the charging gun is inserted into the car, it cannot be charged.

[0031] In this embodiment, the unlocking and charging process includes: If the user needs to unplug the charging gun for charging, the user can connect the Bluetooth communication module 142 through the mobile phone APP Bluetooth to send an unlock charging instruction. After receiving the instruction, the charging control module 14 switches the power supply to the main control module 21 to the PWM adjustable power supply 144 through the switching switch 145, and then sends an unlock instruction to the main control module 21 by changing the PWM output duty cycle of the PWM adjustable power supply 144. After the main control module 21 detects the voltage value representing the unlock instruction through the second voltage detection module 211, it controls the electric lock mechanism 22 to link the lock rod 23 to pull the ejector pin 231 out of the lock slot 112, and the gun head 11 can be pulled out of the gun seat 26. At the same time, after the charging control module detects that the gun head 11 has been pulled out of the gun seat 26 through the first voltage detection module 146, it controls the charging protocol module 141 to be in an available state and disconnects the MOS tube switch 143.

[0032] In this embodiment, the charging pile can be disassembled and moved for use. If the user needs to carry the charging gun to use in other places, he can unlock it according to the previous unlocking method and pull out the gun head, then unlock the password lock, open the box door and unplug the plug, and then carry it to other places for use.

[0033] In this embodiment, the user can also set the output power level of the charging gun, as well as functions such as scheduled nighttime charging, through the mobile phone APP.

[0034] This embodiment makes full use of the existing national standard charging gun hardware interface. The lock control base draws power from the CP interface of the charging gun without the need for an additional power supply, and uses the national standard resistance detection status of the CC interface to achieve intelligent lock control of the charging gun.

[0035] In this embodiment, since the gun head is locked by an electric lock and cannot be pulled out, and the plug at the other end is locked in the box, the physical safety of the charging gun is guaranteed, so there is no safety problem even if the charging gun is charged. Furthermore, since the charging is controlled by Bluetooth via the mobile phone APP, there is no risk of electricity theft even if the charging gun is pried open. Therefore, the relay control system that realizes the on-off function is cancelled, and the charging pile with direct wires is more reliable, has a lower failure rate, and the cost of the charging pile is greatly reduced.

[0036] This embodiment also realizes a usage mode shared by fixed and mobile. The fixed mode in which both ends of the charging gun are locked has high security, and when both ends are unlocked, it can become a mobile mode charging gun. This structure improves the efficiency of equipment use and has better practicality.

[0037] For charging guns with other interface standards such as European standards and American standards, the charging pile provided by this embodiment can be realized by adjusting the corresponding port connections according to the principles of this embodiment.

[0038] The above is a detailed introduction to the fixed and mobile shared charging piles for new energy vehicles provided by the present invention. The description of the above embodiments is only used to help understand the core design ideas of the present invention. At the same time, for those skilled in the art, according to the principles of the present invention, there will be changes in the specific implementation methods and application scopes. Therefore, the content of this specification should not be understood as a limitation on the invention.
