Description

Technical Field

[0001] This invention relates to the field of DC charging and discharging equipment for pure electric vehicles, specifically a high-efficiency DC charging and discharging device. Background Technology

[0002] Pure electric vehicles are a type of new energy vehicle that primarily achieves propulsion through the combination of batteries and motors. DC charging and discharging equipment (charging piles) is one of the supporting facilities for pure electric vehicles, mainly used to charge them. DC charging and discharging equipment (charging piles) includes a DC charger and a charging plug. The DC charger converts AC power into DC power and directly transmits the current to the battery of the pure electric vehicle through the charging plug, achieving fast and efficient charging. With the development of new energy vehicles, the number of charging piles is also increasing.

[0003] In actual use, the connection cable between the charging gun and the charging station of existing DC charging piles is dragged directly on the ground, which makes the cable easily damaged by being run over by wheels. Moreover, the cable sheath is easily damaged by friction with the ground during long-term dragging, resulting in leakage and other problems. To address these issues, a high-efficiency DC charging and discharging device is designed to better meet the needs of actual use. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency DC charging and discharging device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency DC charging and discharging device, comprising a water storage tank and a main body, wherein the main body is fixed on the water storage tank, and an openable door is installed on the main body. A top plate is fixed on the upper surface of the main body, and a charging mechanism is connected to the top plate. A limit plate, a shielding mechanism, and a water cooling mechanism are fixed on the side of the main body, and a cleaning mechanism is installed on the water cooling mechanism. The charging mechanism includes a rotating rod, a round rod, a sliding rod, a fixing frame, a vertical rod, a first spring, a guide wheel, a wire, and a charging gun head. The rotating rod is rotatably connected to the top plate through a bearing, and a round rod is fixed on the rotating rod. The rod has a sliding rod slidably connected to it. A fixed frame is provided on the lower side of the sliding rod, and a vertical rod is fixed to the upper end of the fixed frame. The vertical rod and the sliding rod are slidably connected. A first spring is fixed between the vertical rod and the sliding rod. A guide wheel is connected to the fixed frame by a bearing. The guide wheel is connected to an electric wire. One end of the electric wire is connected to the main housing, and the other end of the electric wire is fixed to the charging gun head. The position of the charging gun head can be adjusted by the rotation of the rod and the sliding action between the rod and the sliding rod. The height of the guide wheel can be adjusted by the elastic action of the first spring to better meet the charging needs.

[0006] Preferably, a water pump is installed on the rear end face of the water storage tank, and two overflow ports are provided on the rear end face of the water storage tank. The overflow ports are connected to the sewer through pipes. Through the function of the overflow ports, automatic drainage can be achieved when the water level in the water storage tank is too high, ensuring the normal operation of the device.

[0007] Preferably, a control panel is fixed on the door, and a rain shield fixed on the door is provided above the control panel. A gunstock is also fixed on the door, and the gunstock and the charging gun head are nested together. Through the nesting action between the gunstock and the charging gun head, the charging gun head can be protected.

[0008] Preferably, the main housing has heat dissipation vents on both the left and right sides, and a cooling fan is fixed on the upper surface of the main housing and is located below the top plate. Through the above structure, the air cooling function inside the main housing can be realized to ensure the normal operation of the device.

[0009] Preferably, a raindrop sensor is fixed on the top plate, and grooves are evenly provided on the upper surface of the top plate. The end of the top plate is located above the water cooling mechanism. Through the function of the raindrop sensor, rainwater can be detected, providing a basic guarantee for the switching between air cooling and water cooling of the device. In conjunction with the function of the grooves on the top plate, rainwater can be collected conveniently.

[0010] Preferably, the shielding mechanism includes a fixed plate, an electric telescopic rod, a movable frame, and baffles. The fixed plate is fixed to the main housing, and the electric telescopic rod is fixed to the lower end face of the fixed plate. The output end of the electric telescopic rod is fixed to the movable frame. Meanwhile, baffles are fixed at equal intervals on the movable frame. The baffles are distributed one-to-one with the heat dissipation vents, and the baffles are positioned by contacting the limiting plate. With the above structure, the heat dissipation vents can be shielded in rainy weather to prevent external water from splashing into the main housing and damaging the electrical components inside the main housing.

[0011] Preferably, the water-cooling mechanism includes a water-cooled box, a liquid level sensor, a water outlet, a water-cooling pipe, a movable rod, a sealing plug, a second spring, a guide rod, a base plate, and a filter screen. The water-cooled box is fixed to the main body and is connected to the water pump via a conduit. A liquid level sensor is installed inside the water-cooled box, and a water outlet is provided on the lower end face of the water-cooled box. The water outlet is connected to the water-cooling pipe via a conduit, and the water-cooling pipe is fixed inside the main body and has a serpentine structure. A filter screen is fixed on the water-cooled box. Through the above structure, a basic guarantee can be provided for the water-cooling heat dissipation of the device. In addition, the serpentine structure of the water-cooling pipe can increase the air contact area, thereby ensuring the water-cooling heat dissipation effect.

[0012] Preferably, a movable rod is slidably connected to the water-cooled box, and a sealing plug is fixed on the movable rod. The sealing plug cooperates with the water outlet to achieve a sealing effect. A second spring is fixed between the movable rod and the fixed plate. Through the above structure, a basic guarantee can be provided for the automatic sealing and sealing release of the water outlet, thereby ensuring the normal operation of the device.

[0013] Preferably, guide rods are symmetrically fixed to the front and rear of the lower end of the water-cooled box, and the guide rods are slidably connected to the fixed plate. The lower end of the guide rod is fixed to the base plate, and the base plate is fixed to the movable frame. When the movable frame moves the base plate, the sliding guidance between the guide rod and the fixed plate can ensure the stability of the movement of the base plate and the water-cooled box.

[0014] Preferably, the cleaning mechanism includes a fixed rod, a cleaning brush, and a connecting rod. The fixed rod is fixed to the upper surface of the water-cooled box, and the cleaning brush is slidably connected to the fixed rod and contacts the filter screen. The cleaning brush is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the main body. When the water-cooled box moves the fixed rod and the cleaning brush, the connecting rod, in conjunction with its transmission action, causes the cleaning brush to slide relative to the filter screen, thereby providing a basic guarantee for cleaning foreign objects such as leaves from the filter screen surface.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This high-efficiency DC charging and discharging equipment adopts an adjustable wire suspension mechanism, which can keep the wire in a suspended state, thereby effectively avoiding damage caused by dragging or being run over by vehicles, and effectively extending the service life of the device. With the help of the elastic buffer mechanism, it can protect the wire when it is pulled, and prevent the wire from jamming or being damaged by violent pulling. Specifically, through the rotation of the rotating rod and the sliding action between the round rod and the sliding rod, the position of the guide wheel and the charging gun head can be adjusted to facilitate the charging operation. With the help of the first spring and the vertical rod, it can provide buffer protection when the wire is pulled violently, and prevent the wire from jamming and being damaged by the guide wheel and the fixed frame.

[0017] 2. This high-efficiency DC charging and discharging equipment employs an automatically adjustable air-cooling and water-cooling mechanism, providing protection against rain and preventing water splashes from damaging electrical components, thus effectively extending the equipment's lifespan. Combined with a linked cleaning mechanism, it can remove foreign objects such as leaves from the filter screen. Specifically, the cooling fan and vents facilitate air circulation within the main chamber, achieving air cooling. During rain, the electric telescopic rod, movable frame, and baffles block the vents, preventing water splashes from entering the main chamber. The movable rod, sealing plug, water-cooling pipes, water tank, and water pump enable water cooling in rainy conditions, improving the equipment's adaptability. Furthermore, when the water-cooling tank lowers, the connecting rod's transmission causes the cleaning brush to move, automatically cleaning the filter screen and ensuring its proper filtration function.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7This invention provides a technical solution: a high-efficiency DC charging and discharging device, including a water storage tank 1 and a main body 2. The main body 2 is fixed on the water storage tank 1, and an openable door 201 is installed on the main body 2. A top plate 207 is fixed on the upper surface of the main body 2, and a charging mechanism 3 is connected to the top plate 207. A limit plate 209, a shielding mechanism 4, and a water cooling mechanism 5 are fixed on the side of the main body 2. A cleaning mechanism 6 is installed on the water cooling mechanism 5. The charging mechanism 3 includes a rotating rod 301, a round rod 302, a sliding rod 303, a fixing frame 304, a vertical rod 305, a first spring 306, a guide wheel 307, a wire 308, and a charging gun head 309. The rotating rod 301 is rotatably connected to the top plate 207 through a bearing, and a round rod 302 is fixed on the rotating rod 301. A sliding rod 303 is slidably connected, and a fixed frame 304 is provided on the lower side of the sliding rod 303. A vertical rod 305 is fixed on the upper end of the fixed frame 304. The vertical rod 305 and the sliding rod 303 are slidably connected. A first spring 306 is fixed between the vertical rod 305 and the sliding rod 303. A guide wheel 307 is connected to the fixed frame 304 by a bearing. The guide wheel 307 is connected to the wire 308. One end of the wire 308 is connected to the main housing 2, and the other end of the wire 308 is fixed to the charging gun head 309. The position of the charging gun head 309 can be adjusted by the rotation of the rotating rod 301 and the sliding action between the round rod 302 and the sliding rod 303. With the elastic action of the first spring 306, the height of the guide wheel 307 can be adjusted to better meet the charging needs.

[0028] A control panel 202 is fixed on the door 201, and a rain shield 203 fixed on the door 201 is provided above the control panel 202. A gunstock 204 is also fixed on the door 201, and the gunstock 204 and the charging gun head 309 are nested together.

[0029] When using this high-efficiency DC charging and discharging equipment, such as Figures 1-7 As shown, during charging, the charging gun head 309 is pulled outward, separating it from the gunstock 204. Combined with the rotation of the rotating rod 301, the direction of the guide wheel 307 can be easily adjusted, thus allowing for position adjustment of the charging gun head 309 to better meet actual charging needs. Furthermore, the sliding action between the round rod 302 and the sliding rod 303 allows for adjustment of the guide wheel 307's front-to-back position, supporting the wire 308 and preventing it from dragging and rubbing against the ground. In actual use, when the wire 308 is violently pulled, the sliding action of the vertical rod 305 and the elasticity of the first spring 306 allow for vertical adjustment of the guide wheel 307, providing a buffering effect and preventing the wire 308 from jamming with the guide wheel 307 and the fixing frame 304, thus ensuring normal operation of the device.

[0030] A water pump 101 is installed on the rear end face of the water storage tank 1, and two overflow ports 102 are provided on the rear end face of the water storage tank 1, and the overflow ports 102 are connected to the sewer through pipes; heat dissipation vents 205 are provided on both the left and right sides of the main tank 2, and a cooling fan 206 is fixed on the upper end face of the main tank 2, and the cooling fan 206 is located below the top plate 207; a rain sensor 208 is fixed on the top plate 207, and grooves are evenly provided on the upper end face of the top plate 207, and the end of the top plate 207 is located above the water cooling mechanism 5; the shielding mechanism 4 includes a fixing plate 401, The system includes an electric telescopic rod 402, a movable frame 403, and baffles 404. A fixed plate 401 is fixed to the main housing 2, and the electric telescopic rod 402 is fixed to the lower end of the fixed plate 401. The output end of the electric telescopic rod 402 is fixed to the movable frame 403. Baffles 404 are fixed at equal intervals on the movable frame 403. The baffles 404 and the heat dissipation vents 205 are distributed in a one-to-one correspondence, and the baffles 404 are positioned by contacting the limiting plate 209. The water cooling mechanism 5 includes a water cooling box 501, a liquid level sensor 502, a water outlet 503, and water cooling pipes 5. 04. Movable rod 505, sealing plug 506, second spring 507, guide rod 508, base plate 509, and filter screen 510. The water-cooled box 501 is fixed on the main body 2 and is connected to the water pump 101 via a conduit. A liquid level sensor 502 is installed inside the water-cooled box 501. An outlet 503 is provided on the lower end face of the water-cooled box 501, which is connected to the water-cooling pipe 504 via a conduit. The water-cooling pipe 504 is fixed inside the main body 2 and has a serpentine structure. A filter screen 510 is fixed on the top; a movable rod 505 is slidably connected to the water cooling box 501, and a sealing plug 506 is fixed on the movable rod 505. The sealing plug 506 cooperates with the water outlet 503 to achieve a sealing effect. A second spring 507 is fixed between the movable rod 505 and the fixed plate 401; guide rods 508 are symmetrically fixed on the front and back of the lower end of the water cooling box 501, and the guide rods 508 are slidably connected to the fixed plate 401. The lower end of the guide rods 508 is fixed on the base plate 509, and the base plate 509 is fixed to the movable frame 403.

[0031] During the use of the device, such as Figures 1-7As shown, when the raindrop sensor 208 does not detect raindrops, the cooling fan 206 starts, working in conjunction with the heat dissipation vent 205 to allow raindrops to enter the main housing 2 through the vent 205 and be exhausted outwards by the cooling fan 206, thus achieving air cooling of the device. When the raindrop sensor 208 detects raindrops, the cooling fan 206 stops operating, and the electric telescopic rod 402 starts to extend. The extension of the electric telescopic rod 402 drives the movable frame 403 and the baffle 404 to move downwards. When the baffle 404 and the limiting plate 209... Upon contact, the electric telescopic rod 402 stops extending, and the baffle 404 effectively blocks the heat dissipation vent 205, thus preventing external water splashes from entering the main housing 2 and damaging electrical components. Furthermore, as the movable frame 403 moves downwards, it simultaneously moves the base plate 509, guide rod 508, and water-cooled box 501 downwards. Combined with the sliding guide action between the guide rod 508 and the fixed plate 401, the stability of the water-cooled box 501's movement is ensured. At this time, the distance between the water-cooled box 501 and the fixed plate 401 decreases. This causes the second spring 507 to contract under force. Under the elastic force of the second spring 507, the movable rod 505 and the sealing plug 506 move upwards relative to the water-cooled box 501, thus separating the sealing plug 506 from the outlet 503. This allows water in the water-cooled box 501 to enter the water-cooling pipe 504 through the outlet 503 and the conduit. Combined with the serpentine structure of the water-cooling pipe 504, this increases the water flow path and flow time. Through the continuous flow of cold water within the water-cooling pipe 504 and the heat exchange effect of the water-cooling pipe 504, the main box 2... The water cooling function ensures the heat dissipation effect of the main box 2 in rainy weather. The water entering the water cooling pipe 504 flows back into the water storage tank 1 through the lower end of the water cooling pipe 504. With the help of the water pump 101 and the conduit, the water in the water storage tank 1 is transported into the water cooling box 501, thereby realizing the recycling of water. In addition, with the help of the top plate 207 and the guide groove on the top plate 207, the rainwater can be guided to enter the water cooling box 501, thereby ensuring that the water cooling box 501 has a sufficient water supply and thus ensuring the water cooling effect of the device.

[0032] The cleaning mechanism 6 includes a fixed rod 601, a cleaning brush 602, and a connecting rod 603. The fixed rod 601 is fixed to the upper end face of the water cooling box 501, and the cleaning brush 602 is slidably connected to the fixed rod 601. The cleaning brush 602 is in contact with the filter screen 510. One end of the cleaning brush 602 is rotatably connected to the connecting rod 603, and the other end of the connecting rod 603 is rotatably connected to the main box 2.

[0033] As the water-cooled box 501 moves downwards, Figures 1-7As shown, with the transmission action of the connecting rod 603, the cleaning brush 602 slides on the fixed rod 601 under force, so that the cleaning brush 602 can clean foreign objects such as leaves on the filter screen 510, ensuring the normal filtering function of the filter screen 510 and preventing foreign objects from entering and causing pipe blockage, which would affect the normal operation of the device. This is the working principle of this high-efficiency DC charging and discharging equipment.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
