[0032] The following is combined with Figure 1-10 The present invention is further described with examples:

[0033] like Figure 1-10 As shown, a safe automobile charging pile includes a base 1, an upper surface of the base 1 is fixedly connected to a column 2, a charging pile body 3 is fixedly connected to the front of the column 2, a movable frame 4 is sleeved on the surface of the charging pile body 3, an inner wall of the movable frame 4 is slidably connected to the surface of the column 2, the movable frame 4 is hollow, and an air outlet 5 is opened on the inner wall of the movable frame 4, and also includes an air generating part connected to the movable frame 4, and bristles 6 are arranged on the inner wall of the movable frame 4 and at the upper and lower sides of the air outlet 5 to loosen the dust on the surface of the charging pile body 3.

[0034] Specifically, a slidable movable frame 4 is provided to cooperate with the air-generating part so that the movable frame 4 can be moved along the vertical direction of the charging pile body 3, and at the same time, the dust on the surface of the charging pile body 3 is cleaned by blowing or sucking air through the air outlet 5. The bristles 6 can be provided to detach the dust that is tightly attached to the surface of the charging pile body 3 due to electrostatic adsorption or humid environment from its original attachment state under the action of friction and stirring, so that the dust can be cleaned by blowing or sucking air through the air outlet 5, thereby improving the cleaning effect. The safe automobile charging pile thus solves the problem in the prior art that the heat dissipation efficiency is affected by the presence of dust on the surface of the charging pile.

[0035] A branch portion 7 and a collecting portion 8 formed at the connection between the two branch portions 7 are formed inside the movable frame 4 . A through hole 9 is formed at the bottom of the collecting portion 8 . A filter is disposed inside the collecting portion 8 .

[0036] The air-generating part includes an installation box 10, which is fixedly connected to the upper surface of the charging pile body 3, and the installation box 10 is communicated with the interior of the charging pile body 3. An installation opening is provided on the upper surface of the installation box 10, and a fan 11 is fixedly connected to the inner wall of the installation opening. A fixed pipe 12 is fixedly connected to the bottom of the charging pile body 3, and a corrugated pipe 14 is fixedly connected to one end of the fixed pipe 12 away from the charging pile body 3. The surface of the corrugated pipe 14 is fixedly connected to the inner wall of the through hole 9, and the fixed pipe 12 is communicated with the charging pile body 3. An avoidance opening 15 for the fixed pipe 12 to pass through is provided on the front of the column 2.

[0037] Specifically, the fan 11 is provided to discharge the air in the installation box 10 to the outside, so that negative pressure is generated at the air outlet 5, and the dust on the surface of the charging pile body 3 is sucked into the branch part 7 and flows to the collecting part 8 with the air flow. The air is filtered by providing a filter at the collecting part 8, and the filtered air enters the charging pile body 3 through the bellows 14 and the fixed tube 12 and is discharged again.

The charging pile body 3 can be cleaned while dissipating heat, and the dust coverage is reduced after cleaning, which further improves the heat dissipation effect. At the same time, it effectively avoids the failure of the charging pile body 3 due to high temperature, thereby improving its safety performance. By cleaning the dust on the surface of the charging pile body 3 in the direction of suction, it is avoided that the dust is dissipated to the surrounding environment due to cleaning, thereby improving environmental friendliness.

[0038] The filter element is a filter screen 16, which is detachably connected to the inner wall of the collecting part 8 in an inclined shape. The filter screen 16 is arranged diagonally along the cross-section of the collecting part 8. The top end of the bellows 14 extends to the inside of the collecting part 8. The bottom surface of the filter screen 16 fits with the top end of the bellows 14. The bellows 14 separates the filter screen 16 into a first filter part 161 and a second filter part 162 corresponding to the bellows 14 to perform secondary filtration of the air. A notch is provided on the surface of the movable frame 4, and the inner wall of the notch is detachably connected to a rear cover 17.

[0039] Specifically, the air is filtered by setting the filter 16, and the filter 16 is tilted and set at the diagonal of the cross section of the collecting part 8, so that the filter 16 can completely separate the collecting part 8, and the first filtration is completed under the action of the first filter part 161. Through the cooperation of the bellows 14, the second filtration is completed under the action of the second filter part 162 when the air flows, thereby reducing the influence of dust in the air on the charging pile body 3, completing two filtrations through one filter 16, and improving the speed of disassembly and cleaning of the filter 16.

[0040] The inner wall of the avoidance opening 15 is fixedly connected to a support plate 18, and the upper surface of the support plate 18 is rotatably connected to a threaded screw 19. The inner wall of the movable frame 4 is fixedly connected to a fixed block 20, and a threaded hole is provided on the upper surface of the fixed block 20, and the surface of the threaded screw 19 is threadedly connected to the inner wall of the threaded hole. The top of the column 2 is provided with an inner recessed groove, and the inner wall of the inner recessed groove is fixedly connected to a motor 21, and the output end of the motor 21 passes through the inner top wall of the avoidance opening 15 and is fixedly connected to the top of the threaded screw 19.

[0041] Specifically, the output end of the motor 21 drives the threaded screw 19 to rotate, thereby driving the fixed block 20 to move, and then driving the movable frame 4 to move, so that the movable frame 4 can move up and down along the charging pile body 3 to complete the comprehensive cleaning of the charging pile body 3, wherein the motor 21 is a forward and reverse motor 21.

[0042] The surfaces of the column 2 and the installation box 10 are fixedly connected with a same fixing plate 22 , the upper surface of the fixing plate 22 is fixedly connected with a same rain cover 23 , and the lower surface of the fixing plate 22 is provided with an air outlet 24 .

[0043] Specifically, the fixed plate 22 is provided to support the rain cover 23, and the rain cover 23 is provided to prevent rainwater from entering the interior of the charging pile body 3, thereby improving safety. The air outlet 24 is provided for exhaust, and the air outlet 24 is provided at the bottom of the fixed plate 22, thereby further preventing rainwater from entering and improving safety performance.

[0044] An operation screen 25 is provided on the front of the charging pile body 3, a cable 26 is fixedly connected to the bottom of the charging pile body 3, and a charging gun 27 is fixedly connected to one end of the cable 26. By setting the cable 26 at the bottom of the charging pile body 3, the cable 26 is placed to hinder the movement of the movable frame 4 during charging.

[0045] A placement seat 13 for placing a charging gun 27 is provided on the front side of the column 2 .

[0046] Cleaning holes 28 are provided on the inner wall of the movable frame 4 and on both upper and lower sides of the air outlet 5 .

[0047] Specifically, by setting the cleaning hole 28, when performing suction dust removal, the suction force at the cleaning hole 28 will directly act on the bristles 6. After the bristles 6 brush the dust from the surface of the charging pile body 3, the dust will stay on the bristles 6 for a short time. At this time, the suction force at the through hole 9 will promptly suck away the dust on the bristles 6 to prevent the dust from falling onto the surface of the charging pile body 3 again, thereby preventing secondary pollution.

[0048] Working principle: When the safe car charging pile is used, the user pulls out the charging gun 27 and inserts it into the charging port of the car, and operates on the operating screen 25 to start charging. When the temperature inside the charging pile body 3 is too high, the fan 11 starts, and the fan 11 discharges the air in the installation box 10 to the outside, so that negative pressure is generated at the air outlet 5, and the dust on the surface of the charging pile body 3 is sucked into the branch part 7 and flows to the collection part 8 with the air flow. The air in the collection part 8 is filtered by the first filter part 161 and flows to the right side of the filter screen 16, and then filtered by the second filter part 162 and flows into the bellows 14 and enters the charging pile body 3 through the fixed pipe 12 and is discharged from the fan 11. In this process, the heat dissipation effect of the charging pile body 3 is improved through air heat exchange. At the same time, the motor 21 is started, and the output end of the motor 21 drives the threaded screw 19 to rotate, the threaded screw 19 drives the fixed block 20 to move, and the fixed block 20 drives the moving frame 4 to move, so that the moving frame 4 can move up and down along the charging pile body 3 to complete the comprehensive cleaning of the charging pile body 3. By combining cleaning with heat dissipation, the charging pile body 3 can be cleaned while dissipating heat, and the dust coverage is reduced after cleaning, which further improves the heat dissipation effect and improves safety. Therefore, the safe automobile charging pile solves the problem of the prior art that the heat dissipation efficiency is affected by the presence of dust on the surface of the charging pile.
