Description

Technical Field

[0001] This utility model belongs to the field of electronic power technology, specifically relating to an outdoor protective DC charging pile. Background Technology

[0002] DC charging stations can directly provide DC power to the battery pack of electric vehicles, bypassing the AC to DC conversion stage of the on-board charger. The charging power is usually large, which can replenish a large amount of power to electric vehicles in a short time and significantly shorten the charging time. For example, some DC fast charging stations can charge an electric vehicle from a low level to about 80% in about 30 minutes to 1 hour. Compared with AC charging stations, this can significantly reduce the user's charging waiting time.

[0003] In some existing DC charging piles, heat dissipation vents are usually provided on the top to meet the heat dissipation requirements of internal electrical components. These vents are mostly designed with an open structure to ensure daily ventilation and heat dissipation. However, in the event of heavy rain or prolonged rainfall, it is usually difficult to close the vents in time, which makes it easy for rainwater to seep into the electrical box. Once rainwater enters, it may cause short circuits, poor contact and other faults in internal electrical components. In severe cases, it may even lead to component burnout and damage to the charging pile. This not only affects the normal operation of the equipment, but also poses safety hazards such as leakage, greatly reducing the reliability and safety of DC charging piles in harsh weather conditions.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figures 1-5 This is an embodiment of the present invention, which provides an outdoor protective DC charging pile, including,

[0029] The charging pile body 100 includes an electrical box 110, charging interfaces 120 respectively fixedly installed on both sides of the electrical box 110, a protective cover 130 disposed above the charging interfaces 120, and a heat dissipation pipe 140 connected to the top of the electrical box 110.

[0030] It should be noted that the electrical box 110 is used to house the core electrical components of the charging pile body 100, such as the charging module and control circuit board, and to provide installation space and physical protection for these components, so as to protect them from external physical impact and harsh environment. The charging interface 120 is used to connect electric vehicles and provide charging channels for vehicles. The protective cover 130 is used to provide additional protection for the charging interface 120 and the charging gun during the charging process, reduce the corrosion of the charging interface 120 by rainwater, dust, and debris, reduce the risk of damage to the charging interface 120 due to external factors, and ensure the stability and safety of the charging connection. Under normal working conditions, the electrical components inside the electrical box 110 generate heat, and the hot air rises and is discharged through the heat dissipation pipe 140 to maintain the electrical components within a suitable operating temperature range and ensure their stable operation.

[0031] The waterproof mechanism 200 includes an opening and closing component 210 for preventing rainwater from entering the electrical box 110 through the heat dissipation pipe 140, which is located inside the heat dissipation pipe 140.

[0032] The opening and closing assembly 210 includes a rotating rod 211 mounted on the inner surface of the heat sink 140 via a bearing sleeve, a first baffle 212 fixedly connected to the outer surface of the rotating rod 211, a rotating sleeve 213 rotatably sleeved on the outer surface of the rotating rod 211, a second baffle 214 fixedly connected to the outer surface of the rotating sleeve 213 and used in conjunction with the first baffle 212, and a plurality of drainage holes 215 opened on the surface of the heat sink 140 for draining accumulated water.

[0033] It should be noted that the rotating rod 211 can drive the first baffle 212 to rotate flexibly, and the rotating sleeve 213 can drive the second baffle 214 to rotate flexibly around the rotating rod 211. When the charging pile body 100 is dissipating heat normally, the first baffle 212 and the second baffle 214 are in the open state, which does not affect the ventilation and heat dissipation of the heat dissipation pipe 140. When it is raining and waterproofing is required, the rotating rod 211 and the rotating sleeve 213 rotate under the drive of the transmission component 230, causing the first baffle 212 and the second baffle 214 to rotate in opposite directions, sealing the heat dissipation pipe 140 and preventing rainwater from entering the electrical box 110. After the heat dissipation pipe 140 is sealed by the first baffle 212 and the second baffle 214, the water accumulated in the heat dissipation pipe 140 can flow out through the drainage hole 215 along the surface of the first baffle 212 and the second baffle 214.

[0034] And a lever component 220 and a transmission component 230, which are located on the outside of the heat dissipation pipe 140, to use the pressure of rainwater to drive the first baffle 212 and the second baffle 214 to close the heat dissipation pipe 140.

[0035] Specifically, the lever component 220 includes a fixed frame 221 integrally formed with the heat dissipation pipe 140, a water collection basin 222 disposed above the fixed frame 221, a slide rod 223 fixedly connected to the bottom of the water collection basin 222, a hinge rod 224 hinged to the through end of the slide rod 223, a slider 225 hinged to the other end of the hinge rod 224, a force-applying groove block 226 fixedly connected to the inner walls on both sides of the slider 225, a drain outlet 227 opened on the surface of the water collection basin 222 for draining accumulated water, a spring 228 sleeved on the outside of the slide rod 223 for driving it to reset, and a fixing block 229 fixedly sleeved on the outside of the slide rod 223 and used in conjunction with the spring 228.

[0036] Furthermore, the outer surface of the slide rod 223 slides in contact with the inner surface of the fixed frame 221, the slider 225 is slidably connected to the inner wall of the fixed frame 221, and the spring 228 is fixedly installed on the top of the fixed frame 221, with its other end abutting against the fixed block 229.

[0037] It should be further explained that the water collection concave plate 222 is used to collect rainwater. After the rainwater falls into the water collection concave plate 222, under the action of gravity, the water collection concave plate 222 will drive the sliding rod 223 to slide vertically downward along the inner surface of the fixed frame 221. The sliding rod 223 pushes the slider 225 to slide along the inner wall of the fixed frame 221 through the hinge rod 224. Then, the slider 225 drives the force-applying groove blocks 226 on both sides to move synchronously. During the sliding process, the force-applying groove blocks 226 cooperate with the transmission component 230 to drive the first baffle 212 and the second baffle 214 to close. The drain outlet 227 is used to drain the water accumulated in the water collection concave plate 222 after the rain stops, so that the spring 228 can reset the water collection concave plate 222 and the sliding rod 223 and other components through the reaction force after the rain stops, thereby driving the first baffle 212 and the second baffle 214 to open.

[0038] Preferably, when rainwater falls into the water collection basin 222, it can be moved vertically downward by gravity; after the rain stops, the water in the water collection basin 222 can be discharged through the drain outlet 227, and then the fixing block 229, the sliding rod 223 and the water collection basin 222 are reset by the reaction force of the spring 228.

[0039] It should be noted that the transmission assembly 230 includes a fixed disk 231 fixedly connected to the outer end face of the rotating rod 211, a first force-bearing column 232 fixedly connected to the outer surface of the fixed disk 231, a connecting sleeve 233 fixedly sleeved on the outer surface of the rotating sleeve 213, and a second force-bearing column 234 fixedly connected to the outer surface of the connecting sleeve 233.

[0040] It should be explained that when the slider 225 slides along the inner wall of the fixed frame 221, the force-applying groove block 226 pushes the first force-bearing column 232 and the second force-bearing column 234 to swing in opposite directions, thereby driving the fixed plate 231 and the connecting sleeve 233 to rotate in opposite directions, and finally causing the rotating rod 211 and the rotating sleeve 213 to rotate in opposite directions, so that the first baffle 212 and the second baffle 214 rotate synchronously in opposite directions, ultimately closing or opening the heat dissipation pipe 140.

[0041] Furthermore, the first force-bearing column 232 and the second force-bearing column 234 are in opposite directions, and the outer surfaces of the first force-bearing column 232 and the second force-bearing column 234 are in sliding contact with the inner walls of the force-applying groove blocks 226 on both sides.

[0042] Specifically, when the slider 225 moves along the fixed frame 221, it can simultaneously push the first force-bearing column 232 and the second force-bearing column 234 to swing through the force-applying groove block 226, thereby causing the first force-bearing column 232 and the second force-bearing column 234 to drive the fixed disk 231 and the connecting sleeve 233 to rotate. Then, the fixed disk 231 and the connecting sleeve 233 drive the rotating rod 211 and the rotating sleeve 213 to rotate. Finally, the rotating rod 211 and the rotating sleeve 213 drive the first baffle 212 and the second baffle 214 to rotate.

[0043] When using,

[0044] Under normal use, the electrical box 110 houses the core electrical components such as the charging module and control circuit board, providing protection and installation space for these components. The charging interface 120 provides a charging channel for electric vehicles, and the protective cover 130 reduces the erosion of the charging interface 120 by external factors, ensuring a stable and safe charging connection.

[0045] The electrical components inside the electrical box 110 generate heat during operation. The hot air is discharged through the heat dissipation pipe 140 on its top to maintain a suitable operating temperature for the components. At this time, the first baffle 212 and the second baffle 214 are in the open state, which does not affect heat dissipation.

[0046] When it rains, rainwater falls into the water collection basin 222. Under the action of gravity, the water collection basin 222 causes the sliding rod 223 to slide vertically downward along the fixed frame 221. The sliding rod 223 pushes the slider 225 to slide along the inner wall of the fixed frame 221 through the hinge rod 224. The slider 225 causes the force-applying groove blocks 226 on both sides to move accordingly. The force-applying groove blocks 226 push the first force-bearing column 232 and the second force-bearing column 234 to swing towards each other. Then, through the first force-bearing column 232... The column 232 and the second force-bearing column 234 drive the fixed plate 231 and the connecting sleeve 233 to rotate in opposite directions, which in turn causes the fixed plate 231 and the connecting sleeve 233 to drive the rotating rod 211 and the rotating sleeve 213 to rotate in opposite directions, which in turn causes the rotating rod 211 and the rotating sleeve 213 to drive the first baffle 212 and the second baffle 214 to rotate in opposite directions, sealing the heat dissipation pipe 140 to prevent rainwater from entering the electrical box 110. After the heat dissipation pipe 140 is sealed, the water inside it flows out through the drainage hole 215.

[0047] After the rain stops, the water accumulated in the water collection basin 222 is discharged through the drain outlet 227. The reaction force of the spring 228 causes the fixing block 229, the sliding rod 223 and the water collection basin 222 to reset, thereby driving the slider 225 to move in the opposite direction. Through the force application groove block 226, the first force column 232 and the second force column 234 swing in the opposite direction, causing the fixing plate 231, the connecting sleeve 233, the rotating rod 211 and the rotating sleeve 213 to rotate in the opposite direction, driving the first baffle 212 and the second baffle 214 to open, so that the heat dissipation pipe 140 can resume its ventilation and heat dissipation function, ensuring that the charging pile continues to work normally.

[0048] In summary, through the cooperation of the various components in the waterproof mechanism 200, not only can the first baffle 212 and the second baffle 214 be automatically driven to close the heat dissipation pipe 140 when encountering rain, preventing rainwater from entering the electrical box 110 through the heat dissipation pipe 140, but also the first baffle 212 and the second baffle 214 can be automatically controlled to open after the rain stops, so that the heat dissipation pipe 140 can restore its ventilation and heat dissipation function. This achieves the effect of ensuring that the charging pile body 100 can work continuously and stably under different weather conditions, while extending its service life.
