Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a rainproof device for electric vehicle charging piles. Background Technology

[0002] If rainwater gets into the socket of an electric vehicle charging station during rainy weather, it can not only cause a short circuit, damage the charging equipment, and interrupt charging, affecting the normal use of the electric vehicle, but also cause electric shock accidents due to leakage, seriously threatening the personal safety of users.

[0003] Patent document CN221162276U discloses a rainproof device for electric vehicle charging piles. This rainproof device includes a support frame and a connecting rainproof mechanism. A control box is mounted on the top of the support frame, and a plug plate is mounted on the front side of the support frame. A rainproof cover is movably connected to the outside of the plug plate. A rainproof plate is movably connected to the top of the front side of the inside of the rainproof cover via a pivot pin. A waterproof pad is fixedly connected to the rear side of the rainproof cover, with the rear side of the waterproof pad contacting the front side of the support frame. A fixing frame is fixedly connected to the front side of the inner wall of the rainproof cover, and a rubber frame is fixedly connected to the front side of the fixing frame, with the front side of the rubber frame contacting the rear side of the rainproof plate. By setting up the connecting rainproof mechanism, when the control box is used in conjunction with the plug plate, it can surround and protect the plug plate, preventing the plug plate from getting wet from rain, which could lead to short circuits or even leakage. Therefore, it improves the usability, installation, and service life of the plug plate. However, this patent still has the following problems in actual use: The rain protection device of this electric vehicle charging station protects the charging plug from rain by setting up a rain shield. However, when the electric vehicle is charging, the rain shield will squeeze the charging plug, causing the connection between the charger plug and the power cord to bend, shortening its service life. In addition, gaps are likely to appear on both sides of the socket, resulting in poor rain protection. Furthermore, the use of a flip-up rain shield requires pressing the rain shield for a long time, making it inconvenient to plug and unplug the electric vehicle charger. Therefore, the rain protection device of this electric vehicle charging station is not very practical.

[0004] Therefore, a rainproof device for electric vehicle charging stations is proposed to solve the problems mentioned above. Utility Model Content

A pressing rod 15 is slidably connected in the middle of the top surface of the locking groove 14. A pressing spring 16 is sleeved on the outer side of the upper end of the pressing rod 15. A pressing plate 17 is fixedly connected to the top of the sliding rod 4; the return springs 5 ​​are symmetrically arranged at both ends of the sliding rod 4; the first shrinkage groove 7 is opened on the side of the driven rain shield 6 away from the active rain shield 12, and the second shrinkage groove 13 is opened on the side of the active rain shield 12 away from the driven rain shield 6; the sliding rod 4 is slidably connected to the side of the driven rain shield 6 and the active rain shield 12 near the shrinkage groove 7 and the second shrinkage groove 13, respectively; the two sets of return springs 5 ​​are fixedly connected to the inner wall of one side of the shrinkage groove 7 and the second shrinkage groove 13, respectively; the driven rain shield 6 and the active rain shield 12 are symmetrically arranged on both sides of the charging socket 2, the driven rain shield 6... The active rain cover 12 is slidably connected to the outer side of the limiting block 3 and the limiting block 8 via the shrink groove 1 7 and the shrink groove 2 13 respectively. The limiting block 3 and the limiting block 8 are fixedly connected to the upper part of the mounting bracket 1 near the charging socket 2. The locking groove 14 is opened on the side of the shrink groove 2 13 near the driven rain cover 6. The locking groove 14 overlaps with the top of the locking block 11. The outer side of the lower end of the locking block 11 is slidably connected to the middle of the lifting groove 9. The bottom surface of the pressing rod 15 overlaps with the top surface of the locking block 11. The two ends of the pressing spring 16 are fixedly connected to the top surface of the active rain cover 12 and the bottom surface of the pressing plate 17 respectively.By setting up symmetrical active rain shields 12 and passive rain shields 6, the charging socket 2 can be easily shielded from all sides, thereby enhancing the rain-blocking effect of the rain shield device and making the electric vehicle charging station safer to use. Furthermore, the clamping groove 23 allows space for the power cord at the electric vehicle charger plug, reducing damage to the charger and improving safety during charging. The locking block 11 engages with the locking groove 14, facilitating quick locking of the active rain shields 12 and passive rain shields 6, ensuring stable deployment. Pressing the pressing plate 17 causes the squeezing rod 15 to push the locking block 11 away from the locking groove 14, and under the action of the return spring 5, the active rain shields 12 and passive rain shields 6 retract and return to their original positions, facilitating plugging and unplugging of the electric vehicle charger, making the rain shield device more convenient and quick to use.

[0018] The active rain shield 12 has an active rack 18 fixedly connected to one side of its lower end. A transmission gear 19 is meshed with one side of the active rack 18. A clearance groove 21 is provided on the side of the active rain shield 12 near the active rack 18. A push plate 22 is fixedly connected to the middle of the end of the active rain shield 12 away from the driven rain shield 6. A clamping groove 23 is provided in the middle of the end of the active rain shield 12 away from the push plate 22. The transmission gear 19 is rotatably connected to the middle of the mounting bracket 1 near the charging socket 2.

The active rack 18 is inserted into the clearance groove 21 on the side of the driven rain shield 6, and the driven rack 20 is inserted into the clearance groove 21 on the side of the active rain shield 12. The transmission gear 19 drives the active rack 18 and the driven rack 20 to retract and extend synchronously, making it more convenient and faster for the active rain shield 12 to retract and extend away from the driven rain shield 6.

[0019] Working principle: When using the rain shield device for the electric vehicle charging station, firstly, by pulling the push plate 22 on one side or pulling the push plate 22 to both sides, the push plate 22 causes the active rain shield 12 to slide outside the limit block 8 through the contraction groove 2 13. At this time, the active rain shield 12 drives the transmission gear 19 to rotate through the active rack 18, causing the active rack 18 to slide in the clearance groove 21. The transmission gear 19 drives the driven rain shield 6 to unfold through the driven rack 20, causing the driven rain shield 6 to slide outside the limit block 3 through the contraction groove 1 7. At this time, the active rain shield 12 and the driven rain shield 6 respectively push the return spring 5 to contract on the sliding rod 4.

[0020] Secondly, the telescopic spring 10 in the lifting groove 9 pushes the locking block 11 to engage with the locking groove 14, thereby locking the positions of the active rain cover 12 and the driven rain cover 6 after they are unfolded, so that the electric vehicle charger can be plugged into the charging socket 2 on one side of the mounting bracket 1.

[0021] Finally, by pressing the pressing plate 17, the compression spring 16 is contracted, and the pressing plate 17 drives the compression rod 15 to push the locking block 11, so that the locking block 11 is separated from the locking groove 14. Under the action of the return spring 5, the active rain cover 12 and the driven rain cover 6 are quickly contracted and clamped on both sides of the electric vehicle charger power cord through the clamping groove 23.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
