Description

Technical Field

[0001] This invention belongs to the field of charging pile technology, specifically a dual-gun charging pile. Background Technology

[0002] A dual-gun charging station is a device that can provide charging services for two electric vehicles simultaneously. It integrates two independent charging modules, supports intelligent load balancing, and can dynamically allocate output power according to vehicle demand. Its core components include a main control unit, dual contactors, a power distribution module, dual communication interfaces, and safety protection devices. The cables of the two charging guns are connected to the corresponding circuits, and efficient and safe parallel charging is achieved through coordinated control. It is suitable for high-demand scenarios such as public fast charging stations.

[0003] A patent application with publication number CN114347826A discloses a dual-gun charging pile, including: a box, a device tray, a module bracket, a first charging gun, a second charging gun, a wire trough, and multiple power charging modules disposed on the box. This application can reduce the crossing of conductive wires by using different wiring, and distribute the conductive wires evenly in the wire trough, so that the conductive wires are neatly and orderly distributed, which is convenient for later maintenance.

[0004] In the application of dual-gun charging piles, although traditional dual-gun charging piles reduce cable crossings and improve safety through unique wiring, in actual use, charging piles are usually installed in parking lots with many vehicles parked. Some gasoline cars occupy charging spaces and are parked side by side. After charging is completed, users may mistakenly believe that the vehicle is just parked and forget to unplug the charging gun from the vehicle. When driving away, the vehicle pulls on the charging pile connected to the charging gun, which can easily directly damage the charging pile, causing significant economic losses and also increasing the great safety hazards.

[0005] Therefore, the present invention provides a dual-gun charging station. Summary of the Invention

[0008] Preferably, the connector head has multiple limiting grooves in a ring shape, and the side of the limiting groove near the connecting hole of the connector head is set as an arc surface; the inner wall of the connector seat is slidably connected to a limiting block through a first elastic element, and multiple limiting blocks are provided, each of which is respectively set to correspond to multiple limiting grooves, and the side of the limiting block near the arc surface of the limiting groove is set as a slope surface; the end of the connector head away from the charging gun is set as an arc surface.

[0009] Preferably, a partition is fixedly connected to the outer wall of the pile body near the two connecting seats; a first fixing frame is fixedly connected to both sides of the partition; and a first fixing plate is fixedly connected to the end of each of the two first fixing frames away from the partition.

[0010] Preferably, the first fixing frame is provided with a sliding groove; a guide box is slidably connected to the sliding groove by a round rod, and the top center of the guide box is hollowed out; a roller is rotatably connected to the inner wall of the guide box.

[0011] Preferably, the side of the guide box closest to the connecting seat is set as an arc surface, and the inner walls of the guide box opposite to the side away from the connecting seat are all set as arc surfaces.

[0012] Preferably, a second fixing frame is fixedly connected to both the partition and the two first fixing frames; a second fixing plate is fixedly connected to the bottom of the second fixing frame and near the two connecting seats; a sealing plate is slidably connected to the outer wall of the second fixing plate; a protrusion is provided on the outer wall of the sealing plate, the protrusion is slidably connected to the inner wall of the second fixing plate, and a second elastic element is installed between the protrusion and the second fixing plate.

[0013] Preferably, the bottom end of the sealing plate is provided with an arc groove, which corresponds to the curvature of the outer wall of the connector.

[0014] Preferably, a storage box is fixedly connected to the outer wall of the pile near the lower part of the two connecting seats; the storage box has a storage cavity inside and a storage slot at the top.

[0015] Preferably, a sealing plate is slidably connected to the outer wall of the storage box; fixing blocks are fixed to both sides of the partition; a connecting rod is fixed to the outer wall of the sealing plate, the connecting rod is slidably connected to the inner wall of the fixing block, and the top end of the connecting rod presses against the protrusion of the sealing plate; a pressure sensor is fixed to the outer wall of the second fixing plate and located below the protrusion of the sealing plate; an alarm light is fixed to the outer wall of the pile, and the pressure sensor is electrically connected to the alarm light.

[0016] Preferably, a rotating shaft is rotatably connected to the first fixing plate via a torsion spring; a connecting plate is fixed to the outer wall of the rotating shaft.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The present invention provides a dual-gun charging station, which replaces the traditional dual-gun charging station where the gun and the station are difficult to separate by inserting a connector into a connector slot. This reduces the economic losses caused by direct damage to the charging station connected to the charging gun when the vehicle pulls on it, and also reduces the safety hazards caused by damage to the charging station. At the same time, the length of the connector is set to half the depth of the connector slot, which can quickly separate the connector from the plug when the vehicle pulls the connector out of the connector slot, reducing the probability of damage to the plug during separation. Multiple limiting blocks clamp the connector from multiple directions, which can limit the connection of the connector and ensure that the connection between the plug and the connector is not affected by the user's pulling force. At the same time, when the vehicle pulls the charging gun away, the arc surface of the limiting groove can squeeze the slope surface of the limiting block to make the connector quickly detach, reducing the damage caused by the separation of the connector and the plug.

[0019] 2. The dual-gun charging pile of the present invention uses a guide box with a hollowed-out section to shield both sides of the cable, limiting the cable to be pulled within the hollowed-out section of the guide box. When the user pulls the cable, the roller can rotate to assist the cable, and the guide position of the cable can be adjusted according to the different positions of the vehicle's charging port, making it easier to pull the cable. It can also be quickly detached when the vehicle pulls the cable, reducing damage to the charging pile. The arc groove of the sealing plate is pressed against the outer wall of the connector top to ensure the stability of the connector and plug connection. As the connector is pulled out of the connector slot, the sealing plate quickly slides down to the connector slot to seal it, enclosing the plug in the connector slot and reducing the probability of the plug being exposed for a long time after the vehicle pulls out the connector, causing safety hazards.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 5As shown in the embodiment of the present invention, a dual-gun charging pile includes a pile body 1; two connecting seats 11 are fixedly connected to the outer wall of the pile body 1; a plug 12 is fixedly connected inside the connecting seat 11, the length of the plug 12 being half the depth of the internal slot of the connecting seat 11; a connector 13 is inserted into the inside of the connecting seat 11, the connector 13 having a connecting hole corresponding to the plug 12, and the length of the connector 13 being the same as the depth of the internal slot of the connecting seat 11; a charging gun 14 is fixedly connected to the outer wall of the connector 13 via a cable; in the application of dual-gun charging piles, the charging piles are usually installed on multiple vehicles. In parking lots, some gasoline cars occupy charging spots and are parked side-by-side. After charging is complete, users may mistakenly believe that the vehicle is just parked and forget to unplug the charging gun 14 from the car. When driving away, the vehicle pulls on the charging station connected to the charging gun 14, which can easily damage the charging station. To reduce the probability of accidents caused by forgetting to unplug the charging gun 14, the charging station body 1 is used as the main structure of the dual-gun charging station. Two connecting seats 11 are fixed to the outer wall of the charging station body 1 near the rear of the parking space. The two connectors 13 of the two charging guns 14, connected by two cables, are inserted into the two connecting seats 11 respectively. In the slot, two charging guns 14 are installed on the charging pile for use. The plug 12, with a depth half that of the slot in the connector 11, is inserted into the connection hole of the connector 13, allowing the charging gun 14 to connect to the power distribution module inside the pile body 1. Since the length of the connector 13 matches the depth of the slot in the connector 11, it maintains its connection to the plug 12 even after being inserted into the slot, without being subjected to extreme pulling force. If the user forgets to unplug the charging gun 14 and drives away, the vehicle will pull on the connector 13 connected to the charging gun 14 during departure, subjecting the connector 13 to extreme force. A large pulling force pulls the charging gun 14 out of the slot of the connector 11, directly separating it from the charging pile 1. The vehicle then tows the charging gun 14 away, replacing the traditional dual-gun charging pile that is difficult to separate from the charging pile. This reduces the economic losses caused by the direct damage to the charging pile connected to the charging gun 14 when the vehicle pulls it out of the slot of the connector 11, and also reduces the safety hazards caused by the damage to the charging pile. At the same time, the length of the plug 12 is set to half the depth of the slot of the connector 11, which can quickly separate the plug 12 from the connector 13 when the vehicle pulls the connector 13 out of the slot of the connector 11, reducing the probability of the plug 12 being damaged during separation.

[0030] The connector 13 has multiple annular limiting grooves 2, with the side of the limiting groove 2 near the connecting hole of the connector 13 being an arc surface. The inner wall of the connector 11 is slidably connected to a limiting block 21 via a first elastic element. Multiple limiting blocks 21 are provided, each corresponding to a different limiting groove 2, and the side of the limiting block 21 near the arc surface of the limiting groove 2 is a slope surface. The end of the connector 13 furthest from the charging gun 14 is an arc surface. When the connector 13 is inserted into the slot of the connector 11 to connect to the plug 12, if the user pulls the charging gun 14 into the vehicle for charging, improper force may easily pull the connector 13 out of the slot, causing poor contact between the connector 13 and the plug 12 and affecting charging. The connector 13 with its arc surface end is inserted into the slot of the connector 11. The arc surface of the limiting block 21 is pressed and slid into the inner wall of the connector 11. The first elastic element contracts and is subjected to force until the limiting block 21 corresponds to the limiting groove 2. The elastic force of the first elastic element drives the limiting block 21 to reset and lock into the limiting groove 2. The multiple limiting blocks 21 clamp the connector 13 in multiple directions. At this time, the connector 13 and the plug 12 are connected. This serves to limit the connection of the connector 13 and ensure that the connection between the plug 12 and the connector 13 is not affected by the user's pulling force. At the same time, when the vehicle pulls the charging gun 14 away, the vehicle generates a strong pulling force to pull the connector 13 connected to the charging gun 14 out of the slot of the connector 11. During the process of pulling out the connector 13, the arc surface of the limiting groove 2 can press the slope surface of the limiting block 21 to make the connector 13 quickly detach, reducing the damage caused when the connector 13 is separated from the plug 12.

[0031] like Figures 1 to 3 As shown, a partition 3 is fixedly connected to the outer wall of the pile body 1 near the two connecting seats 11; a first fixing bracket 31 is fixedly connected to both sides of the partition 3; a first fixing plate 32 is fixedly connected to the end of each of the first fixing brackets 31 away from the partition 3; when the connector 13 is inserted into the connecting seat 11, since the pile body 1 is equipped with two charging guns 14, the cables connecting the two connectors 13 and the charging guns 14 are easy to get tangled, which may cause damage to the charging pile in case of forgetting to unplug the gun. The partition 3 is fixed between the two connecting seats 11 to block the flow, and the first fixing plate 32 is fixed to one side of the partition 3 in conjunction with the first fixing bracket 31 as a support for the cable, thereby separating the two guns and reducing the probability of the two cables getting tangled. At the same time, the cable rests on the first fixing bracket 31, which not only helps the user to plug in the gun for charging more quickly, but also guides the cable to be nearly vertical when the vehicle is pulled out of the connector 13, reducing the wear on the plug 12 when the connector 13 is pulled out of the connector 11 slot.

[0032] like Figures 1 to 4As shown, the first fixing frame 31 has a sliding groove; a guide box 4 is slidably connected to the sliding groove via a round rod, and the top center of the guide box 4 is hollowed out; a roller 41 is rotatably connected to the inner wall of the guide box 4; when the user takes the charging gun 14 and plugs it into the vehicle for charging, the cable connected to the charging gun 14 is placed on the roller 41 in the center of the hollow of the guide box 4. The hollow of the guide box 4 blocks the two sides of the cable, so that the cable is limited to the hollow of the guide box 4 and pulled. When the user pulls the cable, he can rely on the roller 41 to rotate the auxiliary cable, and according to the different positions of the vehicle charging port, the pulled cable can slide in the sliding groove with the round rod at the bottom of the guide box 4 to adjust the guiding position of the cable, making it easier to pull the cable. When the vehicle pulls the cable, it can also quickly detach, reducing damage to the charging pile.

[0033] The guide box 4 has an arc-shaped surface on the side near the connector 11, and the inner walls of the guide box 4 on the side away from the connector 11 are also arc-shaped. When the vehicle pulls away the charging gun 14 that was left unplugged, the connector 13 pulled out of the slot of the connector 11 falls between the connector 11 and the first fixing frame 31 and hangs there. As the vehicle continues to pull, the cable is pulled through the hollow part of the guide box 4. The arc-shaped surface of the guide box 4 guides the connector 13, allowing the connector 13 to slide smoothly through the guide box 4. This reduces the risk of the connector 13 getting stuck in the guide box 4 and damaging the charging pile when the vehicle pulls it. At the same time, the two arc-shaped surfaces of the inner wall of the guide box 4 on the side away from the connector 11 can guide the cable when it is pulled, increasing the angle at which the cable is pulled through the hollow part of the guide box 4 and reducing the damage caused by the cable being kept too bent for a long time after the charging gun 14 is plugged into the vehicle.

[0034] like Figures 1 to 3 , Figure 5As shown, a second fixing bracket 5 is fixedly connected to both the partition 3 and the two first fixing brackets 31; a second fixing plate 51 is fixedly connected to the bottom of the second fixing bracket 5 and near the two connecting seats 11; a sealing plate 52 is slidably connected to the outer wall of the second fixing plate 51; a protrusion is provided on the outer wall of the sealing plate 52, the protrusion is slidably connected to the inner wall of the second fixing plate 51, and a second elastic element 53 is installed between the protrusion and the second fixing plate 51; when the vehicle pulls the charging gun 14 to pull out the connector 13, the plug 12 is exposed for a long time because it is an important component for vehicle charging. The current state is prone to safety hazards. The second fixing bracket 5 is fixed above the two connecting seats 11 to cover the two connecting seats 11. The sealing plate 52 is slidably installed on the outer wall of the second fixing plate 51 through the second elastic element 53. As the connector 13 is pulled out of the slot of the connecting seat 11, the second elastic element 53 quickly pulls the protrusion of the sealing plate 52 down. The sealing plate 52 slides down to the slot of the connecting seat 11 and seals it, sealing the plug 12 in the slot of the connecting seat 11. This reduces the probability of the plug 12 being exposed for a long time after the vehicle pulls the connector 13 out of the connecting seat 11, which would cause safety hazards.

[0035] The bottom end of the sealing plate 52 is provided with an arc groove, which corresponds to the curvature of the outer wall of the connector 13. Before the sealing plate 52 seals the slot of the connector 11, the connector 13 is inserted into the slot of the connector 11 and the connector plug 12 is connected. At this time, the arc groove of the sealing plate 52 is pressed against the outer wall of the top of the connector 13. The second elastic element 53 pulls the sealing plate 52, making the sealing plate 52 press more tightly on the connector 13, ensuring the stability of the connection between the connector 13 and the plug 12.

[0036] like Figure 1 , Figure 2 and Figure 6 As shown, storage boxes 6 are fixedly attached to the outer wall of the pile body 1 near the lower part of the two connecting seats 11. The storage box 6 has a storage cavity inside and a storage slot at the top. Before the vehicle pulls the charging gun 14 away, in order to ensure the normal operation of the dual-gun charging pile, the spare connector 13 and charging gun 14 connected by cable are placed in the storage cavity of the storage box 6 in advance. After the vehicle pulls the charging gun 14 away, the spare gun is taken out and reconnected, thereby ensuring the normal operation of the dual-gun charging pile. At the same time, the storage slot on the storage box 6 can collect the suspended cable and reduce the bending damage at the connection between the connector 13 and the cable caused by the cable being suspended for a long time.

[0037] like Figures 1 to 3 , Figure 5 , Figure 6As shown, a sealing plate 7 is slidably connected to the outer wall of the storage box 6; fixing blocks 71 are fixed to both sides of the partition 3; a connecting rod 72 is fixed to the outer wall of the sealing plate 7, the connecting rod 72 is slidably connected to the inner wall of the fixing block 71, and the top of the connecting rod 72 presses against the protrusion of the sealing plate 52; a pressure sensor 8 is fixed to the outer wall of the second fixing plate 51 and below the protrusion of the sealing plate 52; an alarm light 81 is fixed to the outer wall of the pile body 1, and the pressure sensor 8 is electrically connected to the alarm light 81; when the spare gun is temporarily stored in the storage cavity of the storage box 6, the complex parking environment, especially in outdoor open parking lots, can easily cause damage to the spare gun. The sealing plate 7, together with the connecting rod 72, is suspended on the protrusion of the sealing plate 52. The sealing plate 7 shields the storage cavity of the storage box 6, reducing damage to the spare gun caused by foreign objects. At the same time, after the vehicle pulls the connector 13 out of the connector 11 slot, the connecting rod 72 slides down along the protrusion of the sealing plate 52 against the inner wall of the fixing block 71. The sealing plate 7 then slides down to open the storage cavity of the storage box 6, making it convenient for other users to use the spare gun. After the protrusion of the sealing plate 52 slides down, it can squeeze the pressure sensor 8. After the pressure sensor 8 is squeezed, it sends a signal to the main controller. The main controller then controls the alarm light 81 to sound an alarm, which is used to remind the driver that the gun was not removed when leaving the vehicle and to warn others that there is a problem with this charging station.

[0038] like Figures 1 to 3 As shown, a rotating shaft 9 is rotatably connected to the first fixing plate 32 via a torsion spring; a connecting plate 91 is fixed to the outer wall of the rotating shaft 9; when the vehicle pulls the charging gun 14 away and then re-inserts the spare charging gun 14, pulling the connecting plate 91 cooperates with the rotating shaft 9 to rotate and open the first fixing plate 32, exposing the connecting seat 11. The spare connector 13 is then inserted from the connecting plate 91 into the slot of the connecting seat 11, the cable is laid on the first fixing frame 31, and the spare charging gun 14 is passed through the first fixing frame 31, improving the efficiency of assembling the spare charging gun 14. Subsequently, the connecting plate 91, along with the torsion spring, drives the rotating shaft 9 to reset and seal the first fixing plate 32, continuing to protect the connecting seat 11.

[0039] Working Process: In the application of dual-gun charging piles, when a vehicle leaves, pulling on the charging pile connected to the charging gun 14 can easily damage the charging pile. To reduce the probability of accidents caused by forgetting to unplug the charging gun 14, the pile body 1 is used as the main structure of the dual-gun charging pile. Two connecting seats 11 are fixed to the rear of the outer wall of the pile body 1 near the parking space. The two connectors 13 of the two charging guns 14, connected by two cables, are inserted into the slots of the two connecting seats 11, thus installing two charging guns 14 on the charging pile for use. At this time, the plug 12, which is half the depth of the slot of the connecting seat 11, is inserted into the connecting hole of the connector 13, so that the charging gun 14 can interact with the power distribution module inside the pile body 1. The block connection, because the length of the connector 13 is consistent with the depth of the slot in the connector 11, allows the connector 13 to maintain its connection with the plug 12 even after being inserted into the slot, without being affected by excessive pulling force. If the user forgets to unplug the charging gun 14 and drives away, the vehicle will pull on the connector 13 connected to the charging gun 14 during the departure process. The connector 13 will be pulled out of the slot in the connector 11 by excessive pulling force, directly separating the charging gun 14 from the charging pile 1. Subsequently, the vehicle will tow the charging gun 14 away, replacing the traditional dual-gun charging piles where it is difficult to separate the gun and the pile. This reduces the economic losses caused by the direct damage to the charging pile connected to the charging gun 14 caused by the vehicle pulling on it, and also reduces the safety risks caused by the damage to the charging pile. The length of the plug 12 is set to half the depth of the connector 11 slot, which allows for quick separation of the plug 12 from the connector 13 when the vehicle pulls the connector 13 out of the connector 11 slot, reducing the probability of damage to the plug 12 during separation. When the connector 13 is inserted into the connector 11 slot to connect the plug 12, if the user pulls the charging gun 14 into the vehicle for charging, improper force may easily pull the connector 13 out of the connector 11 slot, resulting in poor contact between the connector 13 and the plug 12 and affecting charging. By using the arc-shaped end of the connector 13 to insert into the slot of the connector 11, the arc-shaped surface of the connector 13 presses against multiple limiting blocks 21, which slide and retract into the inner wall of the connector 11, causing the first elastic element to contract and bear force. Until the limit block 21 corresponds to the limit groove 2, the elastic force of the first elastic element drives the limit block 21 to reset and be inserted into the limit groove 2. Multiple limit blocks 21 clamp the connector 13 in multiple directions. At this time, the connector 13 and the plug 12 are connected, which plays the role of limiting the connection of the connector 13, ensuring that the connection between the plug 12 and the connector 13 is not affected by the user's pulling force. At the same time, when the vehicle pulls the charging gun 14 away, the vehicle generates a strong pulling force to pull the connector 13 connected to the charging gun 14 out of the slot of the connector 11. During the process of pulling out the connector 13, the arc surface of the limit groove 2 can squeeze the slope surface of the limit block 21 to make the connector 13 quickly detach, reducing the damage caused when the connector 13 is separated from the plug 12.

[0040] When connector 13 is plugged into connector 11, the cables connecting the two connectors 13 and the charging guns 14 are prone to tangling because two charging guns 14 are mounted on the charging pile 1. This could damage the charging pile in case of a gun being left plugged in. A partition 3 is fixed between the two connectors 11 to prevent this. A first fixing plate 32, in conjunction with a first fixing bracket 31, is fixed to one side of the partition 3 to support the cables, thus separating the two guns and reducing the probability of tangling. Simultaneously, the cables rest on the first fixing bracket 3. The above not only assists users in quickly plugging in the charging gun, but also guides the cable to near-vertical position when the vehicle is pulled out of the charging gun, reducing wear on the plug 12 when the connector 13 is pulled out of the connector 11 slot; when the user takes the charging gun 14 and plugs it into the vehicle, the cable connected to the charging gun 14 is placed on the roller 41 in the center of the guide box 4's hollow part. The hollow part of the guide box 4 blocks the cable on both sides, so that the cable is limited to the hollow part of the guide box 4 and pulled. When the user pulls the cable, it can rely on The roller 41 rotates the auxiliary cable, and depending on the location of the vehicle's charging port, the pulled cable can slide in the groove along the round rod at the bottom of the guide box 4, adjusting the guiding position of the cable to make pulling the cable easier and allowing it to quickly detach, reducing damage to the charging pile. When the vehicle pulls away from the charging gun 14 that was left unplugged, the connector 13, pulled out of the slot of the connector 11, falls between the connector 11 and the first fixing bracket 31 and hangs there. As the vehicle continues to pull, the cable... During the pulling process at the cutout of the guide box 4, the arc-shaped surface of the guide box 4 is used to guide the connector 13, allowing the connector 13 to slide smoothly through the guide box 4, reducing the risk of the connector 13 getting stuck at the guide box 4 and damaging the charging pile when it is pulled by the vehicle. At the same time, the two arc-shaped surfaces of the inner wall of the guide box 4 away from the connector 11 can guide the cable when it is pulled, increasing the angle at which the cable is pulled from the cutout of the guide box 4, reducing the damage caused by the cable remaining excessively bent for a long time after the charging gun 14 is plugged into the vehicle.

[0041] When the vehicle pulls the charging gun 14 to remove the connector 13, the plug 12, being a crucial component for vehicle charging, is exposed for an extended period, posing a safety hazard. Therefore, a second fixing bracket 5 is used to secure it above the two connectors 11, shielding them. The sealing plate 52 is slidably mounted on the outer wall of the second fixing plate 51 via the second elastic element 53. As the connector 13 is pulled out of the connector 11's slot, the second elastic element 53 quickly pulls the protrusion of the sealing plate 52 down, sealing it at the connector 11's slot. The sealing plate 52 seals the plug 12 within the slot of the connector 11, reducing the probability of the plug 12 being exposed for an extended period after the vehicle pulls the connector 13 out of the connector 11, thus posing a safety hazard. Before the sealing plate 52 seals the slot of the connector 11, the connector 13 is inserted into the slot of the connector 11 to connect the plug 12. At this time, the arc groove of the sealing plate 52 is pressed against the outer wall of the top of the connector 13. The second elastic element 53 pulls the sealing plate 52, making the sealing plate 52 press more tightly against the connector 13, ensuring the stability of the connection between the connector 13 and the plug 12.

[0042] Before the vehicle pulls the charging gun 14 away, to ensure the normal operation of the dual-gun charging station, the spare connector 13 and charging gun 14, connected by a cable, are placed in the storage cavity of the storage box 6. After the vehicle pulls the charging gun 14 away, the spare gun is taken out and reconnected, thus ensuring the normal operation of the dual-gun charging station. At the same time, the storage slot on the storage box 6 can collect the suspended cable, reducing bending damage at the connection between the connector 13 and the cable caused by prolonged suspension. When the spare gun is temporarily stored exposed in the storage cavity of the storage box 6, the complex parking environment, especially in outdoor open parking lots, can easily cause damage to the spare gun. The sealing plate 7 is used in conjunction with the connection... The rod 72 is suspended on the protrusion of the sealing plate 52. The sealing plate 7 blocks the storage cavity of the storage box 6, reducing the damage to the spare gun caused by foreign objects. At the same time, after the vehicle pulls the connector 13 out of the connector 11 slot, the connecting rod 72 slides down the inner wall of the fixing block 71 along with the protrusion of the sealing plate 52. The sealing plate 7 then slides down to open the storage cavity of the storage box 6, making it convenient for other users to use the spare gun. After the protrusion of the sealing plate 52 slides down, it can squeeze the pressure sensor 8. After the pressure sensor 8 is squeezed, it sends a signal to the main controller. The main controller then controls the alarm light 81 to sound an alarm to remind the driver that the gun was not removed when leaving the vehicle and to warn others that there is a problem with this charging station.

[0043] When the vehicle pulls the charging gun 14 away and then plugs in the spare charging gun 14, the connecting plate 91 is pulled to rotate with the shaft 9 to open the first fixing plate 32, exposing the connecting seat 11. The spare connector 13 is then inserted from the connecting plate 91 into the slot of the connecting seat 11, the cable is laid on the first fixing bracket 31, and the spare charging gun 14 is passed through the first fixing bracket 31, improving the efficiency of assembling the spare charging gun 14. Subsequently, the connecting plate 91, driven by the torsion spring, moves the shaft 9 to reset and seal the first fixing plate 32, continuing to protect the connecting seat 11.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
