Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a silent heat dissipation device for a new energy vehicle charging host. Background Technology

[0002] Charging piles are charging devices that provide energy replenishment for electric vehicles. Their function is similar to that of a gas pump in a gas station. They can be fixed to the ground or a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels.

[0003] Existing charging stations generate a lot of heat during charging, requiring multiple fans for cooling. These fans produce significant noise, impacting user experience. While water cooling is quieter, it is more expensive and less convenient to use. Therefore, we propose a silent cooling device for new energy vehicle charging stations to address the aforementioned issues. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing charging piles where the main unit generates a lot of heat during charging, requiring multiple fans for heat dissipation, which generates a lot of noise and affects user experience. Water cooling is quieter but more expensive and inconvenient to use. Therefore, this invention proposes a silent heat dissipation device for the main unit of a new energy vehicle charging pile.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A silent heat dissipation device for a new energy vehicle charging host includes a housing, a charging gun is provided on one side of the housing, a support shell is fixedly connected to the bottom of the housing, and an air intake component for air intake is provided inside the support shell.

[0007] Multiple air vents are provided on both sides of the outer shell. A first partition is fixedly connected inside the outer shell. A second partition is fixedly connected to both sides of the first partition. A sliding plate is slidably connected to both sides of the second partition. A heat dissipation component for heat dissipation is provided inside the sliding plate.

[0008] A second strip-shaped hole is provided on one side of the outer casing, and a pushing component for pushing the sliding plate to move laterally is provided inside the second strip-shaped hole.

[0009] In one possible design, the air intake assembly includes multiple screens fixedly connected inside the support shell, support bases fixedly connected to the four bottom corners of the support shell, and multiple air inlets opened at the bottom of the shell.

[0010] In one possible design, the heat dissipation assembly includes a rectangular hole formed inside the sliding plate, a rotating plate rotatably connected inside the rectangular hole, a tension spring fixedly connected between one side of the sliding plate and one side of the first partition, and support plates fixedly connected to the inner walls of both sides of the housing, the support plates cooperating with the sliding plate.

[0011] In one possible design, the actuating assembly includes a slider slidably connected inside the second slot, a threaded block fixedly connected to one side of the slider, two symmetrically arranged fixing blocks fixedly connected to one side of the housing, a reciprocating screw rotatably connected between the two fixing blocks, the reciprocating screw threaded through the threaded block, a servo motor fixedly connected to one side of one of the fixing blocks, the output shaft of the servo motor rotatably passing through the fixing block and fixedly connected to one end of the reciprocating screw.

[0012] In one possible design, two symmetrically arranged push rods are fixedly connected to one side of the slider. The push rods cooperate with the rotating plate and the sliding plate. A first strip-shaped hole is opened inside the second partition, and the push rod passes through the first strip-shaped hole.

[0013] In one possible design, the inner walls of the top and bottom of the rectangular hole are provided with arc-shaped grooves. A circular plate is rotatably connected to the inner wall of the arc-shaped groove. A circular rod is fixedly connected to the bottom of the circular plate. One end of the circular rod is fixedly connected to one side of the rotating plate. The same torsion spring is fixedly connected between one side of the circular plate and one side of the inner wall of the arc-shaped groove.

[0014] In one possible design, dustproof plates are fixedly connected to both sides of the housing, and the dustproof plates are used in conjunction with the air outlet.

[0015] In one possible design, rubber sheets are provided on both sides of the rotating plate.

[0016] In this application, when heat dissipation is required, the servo motor is started. The output shaft of the servo motor drives the reciprocating lead screw to rotate. The reciprocating lead screw drives the threaded block to move laterally. The threaded block drives the slider to move laterally. The slider drives the two push rods to move laterally. The rotating plate is in an inclined state. At this time, the push rods push the rotating plate to rotate. The rotating plate drives the round rod to rotate. The round rod drives the round plate to rotate, which in turn twists the torsion spring. At this time, the rotating plate enters the interior of the rectangular hole and fits against the inner wall of the sliding plate.

[0017] At the same time, the push rod continues to move, pushing the sliding plate to move laterally. The sliding plate pushes the hot air inside the device out from the inside of the air outlet. At this time, due to the decrease in pressure inside the outer shell, and the sliding plate being above the support plate, the device begins to take in air through the air inlet. The air inlet sends cold air from outside into the device, thereby achieving the function of heat dissipation.

[0018] When the sliding plate rebounds, the rotating plate no longer pushes the rotating plate and the sliding plate. At this time, the rotating plate rotates under the torque of the torsion spring, while the sliding plate rebounds under the tension of the tension spring. As a result, the rotating plate is in an inclined state, and a gap appears between it and the sliding plate. This prevents the air inside the device from being sent out through the first partition. Cool air is sent in from the bottom and sent out from the top, which can better dissipate heat from the entire device. At the same time, the screen can reduce the entry of dust.

[0019] In this invention, the silent heat dissipation device for a new energy vehicle charging host can filter the air and reduce dust accumulation through the air intake component.

[0020] In this invention, the silent heat dissipation device for a new energy vehicle charging host can achieve the effect of sending cold air in from below and expelling hot air from above through the heat dissipation components.

[0021] In this invention, the silent heat dissipation device for a new energy vehicle charging host can achieve a rapid pushing effect by pushing the component;

[0022] In this invention, when heat dissipation is required, the servo motor is started, the push rod pushes the rotating plate to rotate, the sliding plate pushes the hot air inside the device out from the air outlet, and the air inlet sends the cold air outside into the device, thereby achieving the function of heat dissipation. The cold air is sent in from the bottom and sent out from the top, which can better dissipate heat from the whole device. At the same time, the screen can reduce the entry of dust.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1

[0033] Reference Figure 1-7 A silent heat dissipation device for a new energy vehicle charging host, which is used in the field of charging piles, includes: a shell 1, a charging gun 4 is provided on one side of the shell 1, a support shell 2 is fixedly connected to the bottom of the shell 1, an air intake component for air intake is provided inside the support shell 2, the air intake component includes multiple screens 8 fixedly connected inside the support shell 2, support bases 3 are fixedly connected to the four corners of the bottom of the support shell 2, and multiple air inlets 7 are opened at the bottom of the shell 1.

[0034] Multiple air outlets 9 are provided on both sides of the outer casing 1. A first partition 10 is fixedly connected inside the outer casing 1. A second partition 11 is fixedly connected to both sides of the first partition 10. A sliding plate 14 is slidably connected to both sides of the second partition 11. A heat dissipation component for heat dissipation is provided inside the sliding plate 14. The heat dissipation component includes a rectangular hole 22 opened inside the sliding plate 14. A rotating plate 13 is rotatably connected inside the rectangular hole 22. A tension spring 20 is fixedly connected between one side of the sliding plate 14 and one side of the first partition 10. A support plate 12 is fixedly connected to the inner walls of both sides of the outer casing 1. The support plate 12 works in conjunction with the sliding plate 14. At the same time, the push rod 23 continues to move, and the push rod 23 pushes the sliding plate 14 to move laterally. The sliding plate 14 pushes the hot air inside the device out from the air outlet 9. At this time, due to the decrease in pressure inside the outer casing 1, and the sliding plate 14 being above the support plate 12, the device starts to take in air through the air inlet 7. The air inlet 7 sends the cold air from outside into the device, thereby achieving the function of heat dissipation.

[0035] A second strip-shaped hole 28 is provided on one side of the outer casing 1. A pushing assembly for pushing the sliding plate 14 to move laterally is disposed inside the second strip-shaped hole 28. The pushing assembly includes a slider 24 slidably connected inside the second strip-shaped hole 28. Two symmetrically arranged pushing rods 23 are fixedly connected to one side of the slider 24. The pushing rods 23 cooperate with the rotating plate 13 and the sliding plate 14. A first strip-shaped hole 19 is provided inside the second partition plate 11, through which the pushing rods 23 pass. A threaded block 25 is fixedly connected to one side of the slider 24. Two symmetrically arranged fixing blocks 27 are fixedly connected to one side of the outer casing 1. A reciprocating screw 26 is rotatably connected between the two fixing blocks 27, and the reciprocating screw 26 is threaded through a threaded rod. The servo motor 6 is fixedly connected to one side of the fixed block 27 of the servo block 25. The output shaft of the servo motor 6 rotates through the fixed block 27 and is fixedly connected to one end of the reciprocating screw 26. When the servo motor 6 is started, the output shaft of the servo motor 6 drives the reciprocating screw 26 to rotate. The reciprocating screw 26 drives the threaded block 25 to move laterally. The threaded block 25 drives the slider 24 to move laterally. The slider 24 drives the two push rods 23 to move laterally. The rotating plate 13 is in an inclined state. At this time, the push rods 23 push the rotating plate 13 to rotate. The rotating plate 13 drives the round rod 17 to rotate. The round rod 17 drives the round plate 16 to rotate, which in turn twists the torsion spring 15. At this time, the rotating plate 13 enters the interior of the rectangular hole 22 and fits against the inner wall of the sliding plate 14.

[0036] Example 2

[0037] refer to Figure 1-7 Improvements based on Embodiment 1: Arc-shaped grooves 18 are provided on the top and bottom inner walls of the rectangular hole 22. A circular plate 16 is rotatably connected to the inner wall of the arc-shaped groove 18. A circular rod 17 is fixedly connected to the bottom of the circular plate 16. One end of the circular rod 17 is fixedly connected to one side of the rotating plate 13. A torsion spring 15 is fixedly connected between one side of the circular plate 16 and one side of the inner wall of the arc-shaped groove 18. Dustproof plates 5 are fixedly connected to both sides of the outer casing 1. The dustproof plates 5 are used in conjunction with the air outlet 9. Rubber pads are provided on both sides of the rotating plate 13. When the sliding plate 14 rebounds, the rotating plate 13 no longer pushes the rotating plate 13 and the sliding plate 14. At this time, the rotating plate 13 rotates under the torque of the torsion spring 15, and the sliding plate 14 rebounds under the tension of the tension spring 20. As a result, the rotating plate 13 is in an inclined state and a gap appears between it and the sliding plate 14, so that the air inside the device will not be sent out through the first partition 10. The cold air is sent in from the bottom and sent out from the top, which can better dissipate heat from the whole device. At the same time, the screen 8 can reduce the entry of dust.

[0038] However, as is well known to those skilled in the art, the working principles and wiring methods of the charging gun 4 and the servo motor 6 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
