DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 4 A waterproof electric vehicle charging pile plug-in box comprises a mounting seat 1 and a socket 14 arranged in the mounting seat 1. A water retaining box 2 is integrally formed on one side of the mounting seat 1. One end of the water retaining box 2 is rotatably connected to a box cover 3, and both sides of the box cover 3 are bonded with guide frames 13 on multiple inner walls of the box cover 3 in the water retaining box 2. A drainage groove 4 is provided on one outer wall of the box cover 3, and one end of the guide frame 13 is flush with the bottom inner wall of the drainage groove 4. A avoidance groove 9 is provided on the bottom outer wall of the box cover 3. A locking mechanism for fixing the position of the box cover 3 is provided at the bottom of the box cover 3. Water flows into the cavity and flows out from the drainage groove 4, guiding the water flow into the cavity, so that it is difficult for water to enter the interior of the protection box from the gap between the box cover 3 and the water retaining box 2, thereby improving the waterproof performance of the plug-in box.

[0025] The locking mechanism comprises an elastic bracket 7 and a clamping strip 8, the elastic bracket 7 is welded to the bottom outer wall of the box cover 3, the clamping strip 8 is welded to the bottom of the mounting seat 1, and the elastic bracket 7 is clamped with the clamping strip 8, the elastic bracket 7 clamps the clamping strip 8, fixes the box cover 3, and prevents the box cover 3 from being easily opened, thereby improving the protection effect of the plug-in box, the top inner wall of the water retaining box 2 is bonded with a triangular strip 11, and the outer side of the triangular strip 11 is flush with one end of the water retaining box 2, the top inner wall of the water retaining box 2 is bonded with a second water retaining strip 10, and the second water retaining strip 10 is in the cavity between the box cover 3 and the guide frame 13, under the obstruction of the triangular strip 11, it is difficult for the water flow to cross the triangular strip 11 and enter the cavity between the box cover 3 and the guide frame 13, the two sides of the bottom of the box cover 3 are bonded with the first water retaining strip 6, and the first water retaining strip 6 does not exceed the two sides of the box cover 3, and the water flow will be blocked by the first water retaining strip The strip 6 blocks the cross flow, and the water can only flow downward, forcibly changing the direction of the water flow, thereby improving the protection effect of the plug-in box. The bottom outer wall of the box cover 3 is bonded with a pull strip 5, and the pull strip 5 is fixed to the first water retaining strip 6. The box cover 3 is pulled and rotated by the pull strip 5, so that the rotation of the box cover 3 is labor-saving and convenient. One end of the guide frame 13 is bonded with a rubber pad 12, and the rubber pad 12 contacts with the water retaining box 2, thereby improving the sealing between the guide frame 13 and the water retaining box 2. The inner walls on both sides of the water retaining box 2 are bonded with rubber strips 16, and the outer walls on both sides of the box cover 3 are provided with grooves 15, and the rubber strips 16 can be snap-fitted with the grooves 15. The snap-fitting of the rubber strips 16 and the grooves 15 makes it difficult for the water flow to flow into the interior of the protection box from the side seam, and at the same time, the water can only deviate downward or to the left and right sides, but cannot enter the inner wall of the protection box, thereby further improving the waterproof performance of the plug-in box.

[0026] Working principle: When in use, the mounting seat 1 and the socket 14 are both mounted on the frame of the electric vehicle charging pile. When water flows down from the top of the mounting seat 1, the water will flow from the front and both sides of the protective cover composed of the mounting seat 1 and the water retaining box 2. When the water flows from the front, it is difficult to flow back through the triangular bar 11 and enter the cavity between the box cover 3 and the guide frame 13 due to the obstruction of the triangular bar 11. Even if it flows into the cavity, it can flow out from the drainage groove 4, so that it is difficult for water to flow from the box cover 3 and the water retaining box 2. The gap between the rubber strips 16 and the grooves 15 allows water to enter the protective box, thereby improving the waterproof performance of the plug-in box. When water flows through the two sides of the protective cover, the water will flow directly downward under the action of gravity. Due to the engagement of the rubber strips 16 and the grooves 15, it is difficult for water to flow into the protective box from the side seams, thereby further improving the waterproof performance of the plug-in box. At the same time, the water will be blocked by the first water retaining strips 6, and it is also difficult to flow horizontally. The water can only flow downward, forcibly changing the direction of the water flow and improving the protective effect of the plug-in box.

[0027] Finally, it should be noted that: for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this utility model shall be included in the protection scope of this utility model.
