Description

Technical Field

[0001] The present invention belongs to the technical field of DC charging piles, and particularly relates to a modular DC charging pile. Background Art

[0002] As an electric vehicle charging device, the charging pile mainly provides charging services for electric vehicles. At present, there are two types of charging piles required for people to drive electric vehicles. One is a DC charging pile, and the other is an AC charging pile. The charging pile control is modularized. Through the integrated design of devices such as fuses, relays, contactors, watt-hour meters, switching power supplies, shunt resistors, main control boards, monitoring boards, voltage detection and insulation detection modules, and terminal blocks, an independent product is formed and made into a pluggable integrated control module, making the internal structure of the charging pile more spacious, the operation more stable, and the maintenance more convenient.

[0003] For example, an energy-saving DC charging pile with the publication number of CN117087470B includes a charging column body, a cylinder, a base, a pulling rope, and a cable. The charging end of the cable is equipped with a charging gun. Above the base, there is a first transmission structure. At the upper end of the first transmission structure, a second transmission structure is fixedly connected. At the upper end of the second transmission structure, a winding structure is drivingly connected. The other end of the cable is wound around the winding structure. At the upper end of the winding structure, a downward pressure spring is abutted; one end of the pulling rope passes into the inner side of the cylinder and is wound around the first transmission structure. At the other end of the pulling rope, a second driving structure is drivingly connected. A first driving structure is cooperatively arranged on the left side of the second driving structure, and the output end of the first driving structure is drivingly connected to the winding structure.

[0004] In the above patent, when the charging gun and the vehicle charging port are automatically powered off when fully charged, they are still in a connected state, which is prone to load overload, resulting in component heating and temperature rise. If they cannot be separated in time, there may be potential safety hazards. Therefore, we propose a modular DC charging pile. Summary of the Invention

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] Please refer to Figure 1 - Figure 4, the present invention provides a technical solution: a modular DC charging pile, including a charging pile main body 100, a charging gun 101 is arranged on the side of the charging pile main body 100, and a separation mechanism 200 is arranged on the charging gun 101. By arranging the separation mechanism 200, the anti-disconnection effect with the vehicle charging port can be strengthened when the charging gun 101 is charging, avoiding the situation that the charging is affected due to the disconnection caused by shaking between the two. At the same time, the charging parts of the two are cooled and the temperature is monitored during charging. If the temperature is too high and abnormal, the charging gun 101 can be quickly separated from the vehicle charging port to reduce the occurrence of potential safety hazards. The separation mechanism 200 includes a mounting frame 201 installed at the outer end of the charging gun 101. Driving cylinders 202 symmetrically located on both sides of the charging gun 101 are embedded in the mounting frame 201. A vacuum pump 203 is arranged at the inner end of the driving cylinder 202, and a vacuum suction cup 204 is arranged at the inner end of the vacuum pump 203. The vacuum suction cup 204 contacts the vehicle surface to increase the anti-disconnection property of the charging gun 101 during charging. A cooling member 206 extending to the inner end of the charging gun 101 is arranged on the upper surface of the mounting frame 201. A monitoring member 208 is arranged at the inner end of the cooling member 206 to monitor the temperature of the charging gun 101 during charging;

[0034] The cooling member 206 includes a cylinder 2063 embedded in the mounting frame 201. A piston plate 2066 is arranged inside the cylinder 2063. The movement of the piston plate 2066 can squeeze the space of the cylinder 2063. An air pipe 2062 is arranged at the left end of the cylinder 2063. An annular refrigeration pipe 2067 located on the left side of the piston plate 2066 is arranged inside the cylinder 2063, and there are many spaces between the annular refrigeration pipes 2067 to facilitate the flow of gas;

[0035] The monitoring member 208 includes a temperature sensing probe 2083 installed at the left end of the air pipe 2062 to detect the temperature at the connection between the charging gun 101 and the vehicle charging port.

[0036] In this embodiment, preferably, the cooling member 206 further includes an electric telescopic rod 2064 installed at the right end of the cylinder 2063. A support frame 2069 is arranged between the electric telescopic rod 2064 and the cylinder 2063. The operation of the electric telescopic rod 2064 can drive the inner rod 2065 to expand and contract. An inner rod 2065 penetrating the cylinder 2063 and connected to the surface of the piston plate 2066 is arranged inside the electric telescopic rod 2064. A nozzle 2061 is arranged at the left end of the air pipe 2062. An adsorption plate 2068 is arranged on the inner side wall of the left end of the cylinder 2063. The adsorption plate 2068 is a porous adsorption cotton, so that the blown air remains dry.

[0037] In this embodiment, preferably, an installation ring 2081 is sleeved on the left end of the air pipe 2062, a control box 2082 is arranged on the surface of the installation ring 2081, and a temperature sensing probe 2083 is installed on the inner surface of the control box 2082. The temperature sensing probe 2083 is a non-contact sensing probe, which can monitor the temperature at the charging position of the charging gun 101.

[0038] In summary, when the charging gun 101 is inserted into the receiving groove of the charging pile main body 100, at this time, the vacuum suction cup 204 contacts the side surface of the charging pile main body 100, and the vacuum pump 203 evacuates the air inside the vacuum suction cup 204, creating a pressure difference between the vacuum suction cup 204 and the outside world. The vacuum suction cup 204 is firmly adsorbed to the charging pile main body 100, increasing the stability of the charging gun 101 during storage and making it not easy to fall off. When charging is required, air is sent into the vacuum suction cup 204 to eliminate the pressure difference, and the vacuum suction cup 204 is separated from the charging pile main body 100. Hold the charging gun 101 and move it to connect with the vehicle charging port. When connecting, the driving cylinder 202 works, and the internal piston rod extends to drive the vacuum suction cup 204 to move. The vacuum suction cup 204 contacts the vehicle surface and is adsorbed on the vehicle surface, making the charging gun 101 not easy to separate from the vehicle charging port. The charging gun 101 is stably connected to the charging port for charging. At the same time, the temperature sensing probe 2083 can always detect the temperature at the charging positions of both. If the temperature is too high, an abnormal temperature signal can be transmitted to the driving cylinder 202 to make the driving cylinder 202 work. Since the vacuum suction cup 204 is firmly connected to the vehicle surface, as the piston rod extends, the cylinder body of the driving cylinder 202 moves outward, driving the mounting bracket 201 and the charging gun 101 to move outward, and the charging gun 101 is separated from the charging port, preventing potential hazards at the charging position due to high temperature. Similarly, when charging is completed, the internal piston rod of the driving cylinder 202 can be extended to prevent the charging gun 101 from being overloaded when separated from the charging port, increasing the charging safety of the charging gun 101. When the vehicle is charging, the electric telescopic rod 2064 works, and the inner rod 2065 extends to drive the piston plate 2066 to move in the cylinder 2063 towards the charging gun 101, pushing the air inside the cylinder 2063 out and spraying it through the air pipe 2062 and the nozzle 2061 onto the connection between the charging gun 101 and the charging port. As the inner rod 2065 retracts, the piston plate 2066 moves outward, the internal space of the cylinder 2063 becomes larger, and the outside air is sucked into the cylinder 2063. The gas passes through the annular refrigeration pipe 2067 to be cooled, and the cooled gas is pushed out by the piston plate 2066 again. This process is repeated to achieve stable cooling of the charging position of the charging gun 101, reducing heat loss during charging and realizing the charging stability and safety of the charging gun 101.

[0039] Embodiment 2

[0040] Refer to Figure 5 and Figure 6, which is the second embodiment of the present invention.

[0041] In this embodiment, preferably, a charging cable 102 is provided between the charging gun 101 and the side surface of the charging pile main body 100. A storage member 400 for winding the charging cable 102 is provided on the side surface of the charging pile main body 100. By using the storage member 400, the charging cable 102 can be wound in an S shape. Compared with the original annular winding of the charging cable 102, the S shape can avoid the knotting of the charging cable 102 when it is removed, increasing the convenience of removing and using the charging cable 102. Moreover, the used charging cable 102 can be cooled, reducing the adverse effect of temperature on the charging cable 102. The storage member 400 includes a serpentine plate 401 installed on the side surface of the charging pile main body 100. A serpentine cooling plate 402 is embedded inside the serpentine plate 401, and its distribution shape is adapted to the shape of the charging cable 102 winding, facilitating the cooling of the used charging cable 102. The lower ends of the serpentine plate 401 and the serpentine cooling plate 402 are connected to a water tank 403 provided on the side surface of the charging pile main body 100.

[0042] In this embodiment, preferably, a fixing column 404 is vertically provided on the side surface of the serpentine plate 401 to support the charging cable 102. A limiting plate 405 is provided at the outer end of the fixing column 404. A pressing disc 407 is movably provided on the fixing column 404. The space for winding the charging cable 102 between the pressing disc 407 and the serpentine plate 401 is adjustable. A pressing spring 406 is sleeved on the fixing column 404 and its two ends are respectively fixed on the surfaces of the pressing disc 407 and the limiting plate 405. The pressing spring 406 keeps the pressing disc 407 having a pressing effect on the charging cable 102.

[0043] In summary, when the charging cable 102 is rewound after charging, the charging cable 102 can be wound in an S shape on multiple fixing columns 404. At the same time, the pressing disc 407 is pushed outwards, and the pressing spring 406 is gradually compressed. After the charging cable 102 is wound on the fixing columns 404, the pressing disc 407 is pressed by the charging cable 102 under the action of the pressing spring 406, increasing the winding stability of the charging cable 102. At the same time, the serpentine cooling plate 402 cools the wound charging cable 102, quickly reducing the heat loss of the charging cable 102 caused by charging high temperature and increasing the use safety of the charging cable 102.

[0044] Embodiment 3

[0045] Referring to Figure 7 and Figure 8 , which is the third embodiment of the present invention.

[0046] In this embodiment, preferably, a protection mechanism 300 is provided at the top of the charging pile main body 100. By using the protection mechanism 300, the charging pile main body 100 without top shielding can be protected. The unfolded area of the folding baffle 303 can extend to the outside of the charging gun 101 to provide waterproof protection for the placement opening of the charging gun 101. At the same time, the front and rear ends of the folding baffle 303 extend out of the outside of the charging pile main body 100 to expand the protection range of the charging pile main body 100. The protection mechanism 300 includes a folding baffle 303 horizontally located above the charging pile main body 100. The folding baffle 303 is waterproof. The left end of the folding baffle 303 is connected to a fixed seat 301 fixed on the upper surface of the charging pile main body 100. A movable pull plate 302 is provided at the right end of the folding baffle 303. As the movable pull plate 302 moves outward, the folding baffle 303 can be gradually unfolded. A moving member 304 for driving the movable pull plate 302 to move is provided on the upper surface of the charging pile main body 100.

[0047] In this embodiment, preferably, two moving plates 306 penetrating through the movable pull plate 302 are provided on the lower surface of the movable pull plate 302. The moving plates 306 can support the movable pull plate 302. The moving member 304 includes teeth 3041 distributed on the lower surface of the moving plate 306. The distribution length of the teeth 3041 is sufficient for the folding baffle 303 to unfold an appropriate length. A driving gear 3042 is meshed below the teeth 3041. Since the position of the driving gear 3042 does not move, the teeth 3041 and the moving plate 306 can move as they mesh. A connecting shaft 3043 is penetrated between adjacent two driving gears 3042 to realize the synchronous movement of the two driving gears 3042. And a vertical plate for supporting the connecting shaft 3043 is provided at the top of the charging pile main body 100. One end of the connecting shaft 3043 is provided with a driving motor 3044. The driving motor 3044 is fixed to the top of the charging pile main body 100 through a frame to increase the installation strength of the driving motor 3044.

[0048] In this embodiment, preferably, a side shielding member 305 is provided at the end of the movable pull plate 302. By using the side shielding member 305, the movable pull plate 302 can be shielded downwardly to expand the protection range of the charging gun 101. The side shielding member 305 includes a rotating plate 3051 rotatably provided at the end of the movable pull plate 302. A side shielding layer 3052 is provided between the two rotating plates 3051. A driving motor 3053 for driving the rotating plate 3051 to rotate is provided on the side surface of the rotating plate 3051. The driving motor 3053 can be used to drive the rotating plate 3051 to rotate.

[0049] In this embodiment, preferably, the separation mechanism 200 further includes a fixed clamp 205 fixed on the upper surface of the mounting bracket 201. The fixed clamp 205 can play a role in pressing and fixing the cylinder 2063, and the position of the cylinder 2063 in the fixed clamp 205 is adjustable. A pressing rod 207 is screwed on the fixed clamp 205 to fix the cylinder 2063 by using the contact pressing force.

[0050] In summary, when the charging pile main body 100 is installed outdoors without obstacles, the driving motor 3044 can be made to work to drive the two driving gears 3042 to rotate in place. The teeth 3041 meshing with the driving gears 3042 gradually move outwards, driving the moving pull plate 302 to move, and the folding baffle 303 gradually unfolds. The unfolded area covers the area where the charging gun 101 is placed. After the folding baffle 303 is unfolded, the driving motor 3044 stops working, and the driving gears 3042 and the teeth 3041 are in a locked state, so that the moving pull plate 302 will not move. The folding baffle 303 stably shields the upper part of the charging gun 101 from water. At this time, the driving motor 3053 works, and the output shaft at the end drives the rotating plate 3051 to rotate to the right, thereby driving the side shielding layer 3052 to rotate to the right and be in an inclined state, which is convenient for expanding the protection and waterproof range of the charging gun 101 and increasing the use safety and stability of the charging gun 101.

[0051] Embodiment 4

[0052] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0053] When the charging gun 101 is connected to the vehicle charging port for charging, the separation mechanism 200 is used to increase the anti-disconnection effect of the charging gun 101 during charging, and the monitoring component 208 is used to monitor the temperature at the charging location of the charging gun 101. If the temperature is abnormal or the charging is completed, the driving cylinder 202 can be made to push the mounting bracket 201 and the charging gun 101 to move outwards, and the charging gun 101 is separated from the vehicle charging port. During charging, the cooling component 206 can be used to cool down the charging location. After charging is completed, the charging cable 102 is wound on the storage component 400 and the charging cable 102 is cooled. After the charging gun 101 is stored, the protection mechanism 300 can be used to protect the entire charging pile main body 100 and the charging gun 101.
