DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-12 The present invention is further described with examples:

[0036] like Figure 1-12 As shown, a new energy vehicle charging pile with good waterproof and heat dissipation effect includes a shell 1 and a power supply device arranged inside the shell 1, and also includes a connecting line 3 electrically connected to the power supply device, one end of the connecting line 3 is fixedly connected to a charging gun 4, a vent 2 is opened on the side of the shell 1, and the inner wall of the vent 2 is rotatably connected to a rotating shaft 5, and the surface of the rotating shaft 5 is respectively fixedly connected to a baffle 6 and a filter screen 7, and the rotating shaft 5 rotates to drive the filter screen 7 to move out of the vent 2 for cleaning with rainwater.

[0037] A mounting frame 15 is fixedly connected to the inner top wall of the housing 1 , and a heat dissipation fan 16 is fixedly connected to the side of the mounting frame 15 , and the heat dissipation fan 16 corresponds to the vent 2 .

[0038] A housing cover 17 is fixedly connected to the front side of the housing 1 .

[0039] Specifically, the angle between the baffle 6 and the filter 7 is less than 90 degrees, and the preferred angle is 80 degrees. The filter 7 is driven to rotate by the rotating shaft 5, so that the filter 7 originally in a vertical state is rotated to the outside of the vent 2 and is in a tilted downward state. At the same time, the baffle 6 is rotated to a vertical state to close the vent 2 to prevent rainwater from entering the interior of the shell 1. The filter 7 is rinsed with rainwater from the outside, and there is no need for manual disassembly and cleaning, thereby reducing the investment in manpower and material resources. The heat dissipation fan 16 allows the outside air to enter the shell 1 from one vent 2 and be discharged from the other side vent 2, so that the shell 1 dissipates heat, and the filter 7 is used to prevent dust from entering the interior of the shell 1.

[0040] In this embodiment, Figure 2-Figure 6 As shown, a slide groove is provided on the side of the shell 1, and the inner wall of the slide groove is slidably connected to a rack 8, the inner wall of the slide groove is rotatably connected to a gear 9, the rack 8 is meshed with the gear 9, one end of the rotating shaft 5 passes through the inner wall of the slide groove and is fixedly connected to the gear 9, and the upper surface of the shell 1 is fixedly connected to a driving part 10 for driving the rack 8 to move up and down.

[0041] The driving unit 10 includes a water tank 1001 fixedly connected to the upper surface of the shell 1, a groove is opened on the side of the water tank 1001, and the inner wall of the groove is rotatably connected to a rotating rod 1002, and the lower surface of the rotating rod 1002 is slidably connected to the first slider 1003 and the second slider 1004 respectively, the surface of the first slider 1003 is rotatably connected to the first connecting rod 1005, the bottom end of the first connecting rod 1005 is fixedly connected to a floating block 1006, and the floating block 1006 is located inside the water tank 1001, and the surface of the second slider 1004 is rotatably connected to the second connecting rod 1007, the second connecting rod 1007 is in a right angle shape, and the lower surface of the second connecting rod 1007 is fixedly connected to the top of the rack 8, when the floating block 1006 moves to conflict with the inner bottom wall of the water tank 1001, the rotating shaft 5 drives the filter screen 7 to rotate and reset and drain the rainwater.

[0042] A drain pipe 1008 is fixedly connected to the back of the water tank 1001, and the drain pipe 1008 is located at the bottom of the water tank 1001. An overflow pipe 1009 is fixedly connected to the back of the water tank 1001. The height of the overflow pipe 1009 is smaller than the groove, and the inner diameter of the overflow pipe 1009 is larger than the inner diameter of the drain pipe 1008.

[0043] Specifically, when the rain outside is heavy, the drain pipe 1008 cannot drain all the water in the water tank 1001, causing the water level in the water tank 1001 to rise, thereby driving the floating block 1006 to move upward, thereby driving the first connecting rod 1005 to move upward, thereby pushing the end of the rotating rod 1002 close to the first slider 1003 to tilt upward, thereby causing the other end of the rotating rod 1002 to move downward, thereby driving the second connecting rod 1007 to move downward, thereby driving the rack 8 to move downward, thereby driving the gear 9 to rotate counterclockwise, thereby driving the rotating shaft 5 to rotate, thereby driving the filter screen 7 to rotate, so that the filter screen 7 that was originally in a vertical state rotates to the outside of the vent 2 and is in a tilted downward state, and at the same time the baffle 6 rotates to a vertical state. The vent 2 is closed to prevent rainwater from entering the interior of the housing 1, and the filter 7 is rinsed with rainwater from the outside. There is no need for manual disassembly and cleaning, which reduces the investment in manpower and material resources. When the rainwater decreases until it stops, the water in the water tank 1001 is drained by the drain pipe 1008, and the float 1006 moves downward under its own gravity until it fits with the inner bottom wall of the water tank 1001, so that the rack 8 moves upward and drives the gear 9 to rotate clockwise, so that the filter 7 is reset to the vent 2 to filter the air. At the same time, when the filter 7 is reset and rotated, the rainwater attached to it is dried off to prevent rainwater from being brought into the housing 1, keeping the interior dry. The float 1006 has a certain weight and can drive the rotating rod 1002 to rotate without water in the water tank 1001.

[0044] In this embodiment, Figure 7-Figure 12 As shown, a mounting groove is provided on the inner wall of the housing 1, and a drying part 11 is fixedly connected to the inner wall of the mounting groove, a cavity 12 is formed inside the rotating shaft 5, and an end cover 13 is fixedly connected to the inner wall of the cavity 12, and a drying hole 14 connected to the cavity 12 is provided on the surface of the rotating shaft 5, and the drying part 11 introduces the high-temperature air in the housing 1 into the cavity 12 and discharges it from the drying hole 14 to blow toward the filter 7.

[0045] The drying section 11 includes a cylinder 1101 fixedly connected to the inner wall of the mounting groove, a piston 1102 is slidably connected to the inner wall of the cylinder 1101, an air inlet pipe 1103 and an air outlet pipe 1104 connected to the inner cavity of the cylinder 1101 are fixedly connected to the top of the cylinder 1101, the air inlet pipe 1103 is connected to the inside of the outer shell 1, and an air inlet check valve 1105 is fixedly connected to the surface of the air inlet pipe 1103, the air outlet pipe 1104 is fixedly connected to the end cover 13 and connected to the cavity 12, and an air outlet check valve 1111 is fixedly connected to the surface of the air outlet pipe 1104.

[0046] A transmission rod 1106 is fixedly connected to the lower surface of the piston 1102. The transmission rod 1106 is in a right angle shape. The horizontal section of the transmission rod 1106 corresponds to the position of the baffle 6, and the surface of the horizontal section of the transmission rod 1106 is rotatably connected to a rotating sleeve 1107. When the baffle 6 rotates and resets, it pushes the rotating sleeve 1107 so that the transmission rod 1106 drives the piston 1102 to move upward. The inner wall of the cylinder 1101 is fixedly connected to a limiting plate 1108. A connecting port 1109 is provided on the upper surface of the limiting plate 1108. A spring 1110 is provided on the surface of the vertical section of the transmission rod 1106. The top end of the spring 1110 is fixedly connected to the lower surface of the piston 1102, and the bottom end of the spring 1110 is fixedly connected to the upper surface of the limiting plate 1108.

[0047] Specifically, even when not charging, the electronic components and circuits inside the charging pile are still in working condition, and need to maintain a certain standby power consumption to provide the functions required for normal operation. Therefore, the charging pile will generate a certain amount of heat regardless of whether it is in the charging state or not. Even when the cooling fan 16 is in working condition, this heat will still make the air temperature inside the shell 1 higher than the outside air temperature. Therefore, the rotating shaft 5 drives the baffle 6 to rotate to open the vent 2, and drives the rotating sleeve 1107 to move through the baffle 6, thereby driving the transmission rod 1106 to move upward, and then driving the piston 1102 to move upward, and the higher temperature air in the cylinder 1101 is discharged from the outlet pipe 1104 into the cavity 12, and blown to the filter 7 from the drying hole 14. The higher temperature air further dries the filter 7 to prevent it from bringing rainwater into the shell 1.

[0048] Working principle: During the use of the new energy vehicle charging pile with good waterproof and heat dissipation effect, when the outside rain is heavy, the drain pipe 1008 cannot drain the water in the water tank 1001, causing the water level in the water tank 1001 to rise, thereby driving the floating block 1006 to move upward, and the floating block 1006 drives the first connecting rod 1005 to move upward, and the first connecting rod 1005 pushes the end of the rotating rod 1002 close to the first slider 1003 to tilt upward, thereby causing the other end of the rotating rod 1002 to move downward, thereby driving the second connecting rod 1007 to move downward, and the second connecting rod 1007 is driven to move downward. 007 drives the rack 8 to move downward, the rack 8 drives the gear 9 to rotate counterclockwise, the gear 9 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the filter screen 7 to rotate, so that the filter screen 7 originally in a vertical state rotates to the outside of the vent 2 and is in a tilted downward state, and at the same time, the baffle 6 rotates to a vertical state to close the vent 2 to prevent rainwater from entering the interior of the housing 1. In this process, the baffle 6 no longer supports the rotating sleeve 1107. Under the action of the spring 1110, the transmission rod 1106 moves downward, and the transmission rod 1106 drives the piston 1102 to move downward, so that the interior of the housing 1 The air with higher temperature enters the cylinder 1101 through the air inlet pipe 1103. When the rain decreases or stops, the water in the water tank 1001 is drained by the drain pipe 1008. The floating block 1006 moves downward under its own gravity until it fits with the inner bottom wall of the water tank 1001, so that the rack 8 moves upward and drives the gear 9 to rotate clockwise, so that the filter 7 is reset to the vent 2 to filter the air. At the same time, when the filter 7 is reset and rotated, the rainwater attached to it is dried to prevent the rainwater from being brought into the shell 1, keeping the inside dry. The rotating shaft 5 rotates clockwise to drive the filter 7 When resetting, the baffle 6 is driven to rotate to open the vent 2, the baffle 6 drives the rotating sleeve 1107 to move, the rotating sleeve 1107 drives the transmission rod 1106 to move upward, the transmission rod 1106 drives the piston 1102 to move upward, and the air with higher temperature in the cylinder 1101 is discharged from the air outlet pipe 1104 into the cavity 12, and blown to the filter 7 from the drying hole 14. The air with higher temperature further dries the filter 7 to prevent it from bringing rainwater into the outer shell 1. The present invention utilizes external rainwater to flush the filter 7, and there is no need for manual disassembly and cleaning, thereby reducing the investment of manpower and material resources.

[0049] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
