Technical Field

[0001] The present invention belongs to the technical field of charging piles, and in particular relates to a new energy vehicle charging pile. Background Art

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electric energy to electric vehicles, enabling them to store enough electricity to support their operation. At present, the prospects for new energy vehicles are becoming more and more broad, and the charging problem of new energy vehicles is becoming more and more prominent. Since new energy vehicles are mainly charged by charging piles, the current charging methods of charging piles are divided into fast charging and slow charging. However, even fast charging basically takes more than an hour, which leads to car owners often choosing to leave the car or handle other matters during the charging process, leaving the car in front of the charging pile. Therefore, it is often the case that the car has been fully charged but still remains in place to occupy the charging head, causing inconvenience to later users. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a new energy vehicle charging pile, which has the beneficial effect that the present invention can automatically disconnect after the vehicle is charged, providing convenience for subsequent users.

[0020] like Figure 1-9 As shown:

[0021] A new energy vehicle charging pile includes a main box 000, a main transmission line 010 is arranged inside the main box 000, the main transmission line 010 can be wound by a winding device and placed inside the main box 000, and can automatically retract after being stretched, the winding device is a mature technical solution, which will not be repeated here, a plug connector 011 is arranged at the end of the main transmission line 010, a transmission slot 001 is opened at the lower side of the main box 000, a conveyor belt 100 is installed inside the transmission slot 001, a plurality of transmission heads 200 are placed on the conveyor belt 100, the transmission head 200 includes a terminal transmission line 210, and a charging head 25 is threadedly connected to the lower side of the terminal transmission line 210 0, a dust cover 220 is slidably connected to the terminal transmission line 210, and a positioning block 230 and a push block 240 are connected to the upper side of the dust cover 220 by screws. The positioning block 230 is arranged on the left and right opposite sides of the terminal transmission line 210, and the push block 240 is arranged on the front and rear opposite sides of the terminal transmission line 210. A plug slot 211 corresponding to the plug connector 011 is arranged on the upper side of the terminal transmission line 210. A charging device is also installed inside the main box 000. The charging device can output current and control signals to the outside through the main transmission line 010. This charging device is a mature general technology and will not be repeated here. The push block 240 can receive the control signal sent by the charging device;

[0022] When the charging pile is put into use, the main transmission line 010 is connected to the transmission head 200 on the far left through the plug connector 011 and the plug slot 211. The user can take out the transmission head 200 on the far left and slide the dust cover 220 upward to expose the charging head 250. Then the charging head 250 can be connected to the charging port of the car for charging. At this time, since the charging head 250 is connected to the charging port of the car and the winding device cannot pull the main transmission line 010 back, when charging is completed, the charging device can send a control signal to the push block 240, so that the push block 240 can be started, so that the push block 240 pushes the plug connector 011, thereby separating the plug connector 011 from the plug slot 211, so that the winding device can pull the main transmission line 010 back. When other users want to use the charging pile for charging, When charging, the user can insert the plug connector 011 on the lower side of the main transmission line 010 into the plug slot 211 on another transmission head 200, so as to continue to charge the electric vehicle by connecting the charging head 250 to the charging port, without removing the previous transmission head 200 from the electric vehicle of the previous user, thereby preventing other users from being unfamiliar with the electric vehicle being charged and causing damage to the charging port of the car being charged due to misoperation. At the same time, it can avoid the waste of resources caused by the electric vehicle occupying the charging pile for a long time for charging, and can increase the frequency of use of a single charging line on the charging pile. At the same time, it can be judged that the electric vehicle has been charged through the action of retracting the main transmission line 010, which provides convenience for users who are not in the car, and at the same time;

[0023] A recycling frame can be provided on one side of the charging pile, so that the user can put the used transmission head 200 into the frame and recycle it, thereby avoiding the transmission head 200 from being lost or wasted;

[0024] At the same time, when the user slides the dust cover 220 upward, when the dust cover 220 slides to the connection position between the plug slot 211 and the plug connector 011, the positioning block 230 can be inserted into the plug slot 211, thereby limiting the position of the dust cover 220, thereby ensuring that the push block 240 can accurately push the plug connector 011 out after charging is completed;

[0025] At the same time, the transmission head 200 can be driven forward by rotating the conveyor belt 100, so that the leftmost transmission head 200 can stay under the main transmission line 010, providing convenience for the user to connect the plug connector 011 with the plug slot 211;

[0026] At the same time, the provision of the dust cover 220 can protect the charging head 250 through the dust cover 220 when the charging head 250 does not need to be connected to the charging port for charging, thereby preventing the charging head 250 from being damaged.

[0027] like Figure 7 As shown:

[0028] The plug slot 211 is provided with through slots 212 at both the front and rear sides, and the plug connector 011 is connected with movable blocks 012 corresponding to the through slots 212 at both the front and rear sides through springs;

[0029] When it is necessary to connect the main transmission line 010 with the terminal transmission line 210, the movable block 012 can be pressed into the inner side of the plug connector 011 so that the plug connector 011 can be inserted into the end transmission line 210. When the plug connector 011 moves to the corresponding position of the movable block 012 and the through slot 212, the movable block 012 can be reset under the action of the spring force so that the movable block 012 is inserted into the through slot 212, thereby easily completing the connection between the main transmission line 010 and the terminal transmission line 210.

[0030] Further:

[0031] The left and right sides of the plug-in slot 211 are planes, and the inner side of the positioning block 230 is connected with a positioning insert 231 through a spring, so that when the dust cover 220 is pushed upward along the terminal transmission line 210 to the connection position between the main transmission line 010 and the terminal transmission line 210, the positioning insert 231 is tightly attached to the planes on the left and right sides of the plug-in slot 211 through the elastic force of the spring, so that the dust cover 220 can accurately stay at the connection position between the main transmission line 010 and the terminal transmission line 210, thereby ensuring that the push-separation block 240 can accurately push the main transmission line 010 and the terminal transmission line 210 to separate;

[0032] At the same time, since both sides of the plug-in slot 211 are flat, the plug-in connector 011 can be limited when being inserted into the inner side of the plug-in slot 211 to avoid relative rotation between the plug-in connector 011 and the plug-in slot 211, thereby preventing the movable block 012 from being able to be inserted into the through slot 212.

[0033] like Figure 8 As shown:

[0034] The inner side of the push-and-divide block 240 is connected with a telescopic push rod 241 by screws. The outer diameter of the telescopic push rod 241 is smaller than the inner diameter of the movable block 012. When the push-and-divide block 240 receives a control signal from the charging device, the push-and-divide block 240 can control the telescopic push rod 241 to extend, so that the telescopic push rod 241 can push the movable block 012 inside the through slot 212, so that the plug connector 011 can be disengaged from the plug connector slot 211, thereby automatically completing the separation of the main transmission line 010 and the terminal transmission line 210.

[0035] like Figure 7 As shown:

[0036] The positioning plug 231 has the same height as the plug slot 211, and the height of the plug connector 011 is smaller than the plug slot 211; thereby, it can be ensured that when the plug connector 011 is inserted into the end transmission line 210, the upper side of the plug connector 011 can be set close to the upper side of the end transmission line 210, and at the same time, when the positioning plug 231 is inserted into the side of the plug slot 211 under the action of the spring force, the upper and lower ends of the positioning plug 231 can respectively be close to the end transmission line 210 and the main transmission line 010, thereby ensuring that the dust cover 220 can be accurately inserted into the connection between the main transmission line 010 and the end transmission line 210 without shaking, and further ensuring that the telescopic push rod 241 can accurately push the movable block 012 inside the through slot 212.

[0037] like Figure 6-7 As shown:

[0038] The upper side of the dust cover 220 is connected with a protective cover 260 by screws. The protective cover 260 is arranged on the outside of the positioning block 230 and the pushing block 240, and a toggle hole 261 is opened on the inner side of the protective cover 260; thereby, the positioning block 230 and the pushing block 240 can be shielded by the protective cover 260 to prevent the positioning block 230 and the pushing block 240 from being deformed by collision during use. At the same time, the setting of the toggle hole 261 enables the user to manually press the positioning plug 231 to separate the positioning plug 231 from the side of the plug-in slot 211 and reset it.

[0039] like Figure 4 As shown:

[0040] The conveyor belt 100 includes two rotating shafts 110, and the two rotating shafts 110 are both rotatably connected to the inner side of the transmission groove 001, one of the rotating shafts 110 is connected to a rotating motor capable of driving the rotating shaft 110 to rotate, and a synchronous belt 120 is sleeved on the outer side of the two rotating shafts 110, and a plurality of transmission pallets 130 are bonded to the synchronous belt 120, and the transmission heads 200 are all placed on the upper side of the corresponding transmission pallets 130, so that the rotating shaft 110 can be driven to rotate counterclockwise by the rotation of the rotating motor, thereby driving the synchronous belt 120 to rotate counterclockwise, and driving the transmission head 200 to gradually move from right to left through the transmission pallet 130, so that the leftmost transmission head 200 can automatically move to the lower side of the main transmission line 010.

[0041] like Figure 2 and 5 As shown:

[0042] A position sensor 003 is provided on the upper side of the transmission slot 001, and a sensing sheet 131 corresponding to the position sensor 003 is provided on the transmission pallet 130. A device capable of storing and automatically adding a transmission head 200 can be connected to the right side of the main chassis 000. When the position sensor 003 does not sense the presence of the sensing sheet 131 on the lower side, it proves that there is no transmission pallet 130 on the lower side of the position sensor 003 or there is a transmission pallet 130 with a transmission head 200 placed thereon, and the device will not be started at this time. When the position sensor 003 senses the presence of the sensing sheet 131 on the lower side, it proves that there is a transmission pallet 130 on the lower side of the position sensor 003 without a transmission head 200 placed thereon, and the device can be started at this time to place a transmission head 200 on the upper side of the transmission pallet 130, thereby completing the automatic replenishment of the transmission head 200.

[0043] like Figure 5 As shown:

[0044] The sensor plate 131 is surrounded by side guardrails 132 , and the dust cover 220 can be stuck inside the side guardrails 132 , thereby preventing the transmission head 200 from sliding off the transmission pallet 130 when being driven by the conveyor belt 100 .

[0045] like Figure 2-3 As shown:

[0046] A position blocking block 002 is arranged on the upper left side of the transmission slot 001, and a pressure sensor is arranged on the position blocking block 002. When the leftmost transmission head 200 follows the transmission pallet 130 to move to the lower side of the main transmission line 010, the leftmost transmission head 200 can be attached to the position blocking block 002, so that the pressure sensor sends a signal, and then the signal generated by the pressure sensor can stop the rotating motor, so that the leftmost transmission head 200 automatically stays on the lower side of the main transmission line 010.
