[0025] Embodiment

[0026] As Figures 1-5 shown, a combined sealing ring for a new energy charging pile includes a housing 1. Both sides of the outer surface of the housing 1 are fixedly connected with cylinder seats 2. One end of the cylinder seat 2 is fixedly connected with a first sealing ring 3. The outer surface of the first sealing ring 3 is fixedly connected with a connecting pipe 4. One end of the connecting pipe 4 is fixedly connected with a second sealing ring 5. The inner side surface of the cylinder seat 2 is movably connected with a charging head 6. A sealing groove 7 is opened on one side of the outer surface of the charging head 6 close to the second sealing ring 5; A spring 8 is fixedly connected to the outer surface of the cylinder seat 2. One end of the spring 8 is fixedly connected with a fixing ring 9. The outer surface of the fixing ring 9 is fixedly connected with a sleeve 10. A limiting bead 11 is movably connected to one side of the inner wall of the cylinder seat 2 close to the fixing ring 9. A limiting groove 12 is opened on one side of the outer surface of the charging head 6 close to the limiting bead 11.

[0027] During specific use, through the settings of the cylinder seat 2, the first sealing ring 3, the connecting pipe 4, the second sealing ring 5, the sealing groove 7, the spring 8, the limiting bead 11 and the limiting groove 12, the sleeve 10 is pulled backward to compress the spring 8, and the fixing ring 9 exposes the top space of the limiting bead 11. Then the charging head 6 is inserted into the inside of the cylinder seat 2 to reduce the probability of rainwater entering the inside of the charging head 6. When the charging head 6 is inserted, the first sealing ring 3 is squeezed, and the gas inside the first sealing ring 3 is transported to the inside of the second sealing ring 5 through the connecting pipe 4, so that the second sealing ring 5 is inflated to fill the inside of the sealing groove 7. The first sealing ring 3 increases the sealing performance at the connection between the charging head 6 and the end face of the cylinder seat 2, and the second sealing ring 5 increases the sealing performance at the connection between their inner side surfaces. The multiple sealing structures prevent water from entering the inside of the charging head 6 and getting damp, thereby protecting the charging head 6 and the charging pile, improving the sealing effect, thus improving the waterproof performance, avoiding potential safety hazards. At the same time, the sleeve 10 is released, and under the elastic action of the spring 8, the fixing ring 9 resets, so as to press the limiting bead 11 to be clamped inside the limiting groove 12, preventing the charging head 6 from loosening, making their connection tighter and more secure, and enhancing the use stability, realizing the convenience of disassembly and charging.

[0028] In this embodiment, a charging wire 13 is fixedly connected to the lower surface of the charging head 6, the charging wire 13 is fixedly connected to the housing 1, and a third sealing ring 14 is fixedly connected to one side of the lower surface of the housing 1 close to the charging wire 13.

[0029] During specific use, through the setting of the third sealing ring 14, the third sealing ring 14 enhances the sealing performance between the charging cable 13 and the housing 1, preventing rainwater from splashing into the interior of the housing 1 and improving the waterproof and sealing properties of the device.

[0030] In this embodiment, brackets 15 are fixedly connected to both sides of the upper surface of the housing 1, and a top plate 16 is fixedly connected to the outer surface of the brackets 15.

[0031] During specific use, through the setting of the top plate 16, the brackets 15 are used to support and fix the top plate 16, which protects the top of the housing 1 from rainwater and serves as a sunshade and rain shield. [[ID=??]]

[0032] In this embodiment, a cooling fan 17 is fixedly connected to the middle of the inner top wall of the housing 1.

[0033] During specific use, through the setting of the cooling fan 17, the cooling fan 17 can dissipate the heat generated by the operation of the electrical components inside the charging pile, further enhancing the heat dissipation effect.

[0034] In this embodiment, a ventilation slot 18 is formed in the middle of the upper surface of the housing 1, and a dust-proof mesh plate 19 is snap-fitted inside the ventilation slot 18.

[0035] During specific use, through the setting of the dust-proof mesh plate 19, the ventilation slot 18 allows the top of the housing 1 to breathe, preventing the interior from being unable to exchange heat and enabling the air inside the housing 1 to circulate. The dust-proof mesh plate 19 ensures ventilation and heat dissipation while reducing the entry of dust.

[0036] In this embodiment, a heat-conducting plate 20 is movably connected to the back of the housing 1 by bolts, and heat-dissipating fins 21 are fixedly connected to the outer surface of the heat-conducting plate 20.

[0037] During specific use, through the setting of the heat-conducting plate 20, the heat-conducting plate 20 can guide the heat generated by the operation of the electrical components inside the housing 1. Under the action of multiple heat-dissipating fins 21, the speed of heat dissipation is accelerated, further enhancing the heat dissipation efficiency of the charging pile.

[0038] In this embodiment, support columns 22 are fixedly connected to the four corners of the lower surface of the housing 1.

[0039] During specific use, through the setting of the support columns 22, the support columns 22 raise the height of the housing 1, reducing the possibility of the charging pile being soaked in large amounts of water and preventing the surface and interior of the charging pile from rusting due to long-term immersion in water, thereby reducing the possibility of damage to the charging pile and its internal equipment.

[0040] In this embodiment, a bottom plate 23 is fixedly connected to the lower surface of the support column 22, and mounting holes 24 are formed at the four corners of the upper surface of the bottom plate 23.

[0041] During specific use, through the setting of the bottom plate 23, four mounting holes 24 are opened at the four corners of the upper surface of the bottom plate 23, which facilitates fixing the bottom plate 23 at a specified position and enhances the stability of the charging pile during use.

[0042] Working principle: During use, the sleeve 10 is toggled backward, causing the spring 8 to be compressed. The fixing ring 9 exposes the top space of the limit bead 11. Then, the charging head 6 is inserted into the inside of the barrel base 2. At the same time, the charging head 6 presses the first sealing ring 3, and the gas inside it is transported through the connecting pipe 4 to the inside of the second sealing ring 5, causing the second sealing ring 5 to be inflated and fill the inside of the sealing groove 7. The multiple sealing structures prevent water from entering the inside of the charging head 6 and getting it damp. In this way, the charging head 6 and the charging pile are protected. When the sleeve 10 is released, under the elastic action of the spring 8, the fixing ring 9 resets, and thus the limit bead 11 is pressed to be clamped inside the limit groove 12, preventing the charging head 6 from loosening and making the connection between the two more tight, realizing the convenience of disassembling and assembling for charging use. The third sealing ring 14 enhances the sealing performance of the connection between the charging cable 13 and the housing 1, preventing rainwater from splashing into the inside of the housing 1 when it rains. The top plate 16 protects the top of the housing 1 to prevent rainwater from entering. The cooling fan 17 can dissipate the heat generated by the operation of the electrical components inside the charging pile. The ventilation slots 18 enable the top of the housing 1 to be ventilated. The dust-proof net plate 19 ensures ventilation and heat dissipation while reducing the entry of dust. The heat-conducting plate 20 and the heat-dissipating fins 21 are used in cooperation to further enhance the heat dissipation efficiency of the charging pile. The support columns 22 raise the height of the housing 1, making it less likely for the surface and inside of the charging pile to rust due to long-term immersion in water.
