[0013] In one possible implementation, let L1 be the distance from the top of the fourth end face to the bottom wall, and L2 be the distance from the bottom of the fourth end face to the bottom wall, then L1 > L2.

[0014] In one possible implementation, let D1 be the distance from the midpoint of the first end face to the bottom wall, and D2 be the distance from the midpoint of the second end face to the bottom wall, then D2 > D1.

[0015] In one possible implementation, along the direction from high to low, the third end face of the left side wall sequentially includes a first segment and a second segment, and the fourth end face of the right side wall sequentially includes a third segment and a fourth segment.

[0016] Along the direction from high to low, the distance between the first segment and the bottom wall and the distance between the third segment and the bottom wall gradually increase, while the distance between the second segment and the bottom wall and the distance between the fourth segment and the bottom wall gradually decrease. The third end face and the fourth end face are the ends of the left side wall and the right side wall that are away from the bottom wall, respectively.

[0017] Along the direction from high to low, the distance between the first segment and the third segment gradually increases, while the distance between the second segment and the fourth segment gradually decreases;

[0018] The projections of the second segment, the second end face, and the fourth segment along the height direction form a W shape.

[0027] This disclosure provides a charging pile in which, when external water enters the first sealing groove, it flows downwards along the groove under gravity, eventually flowing towards the drain hole and then out of the charging pile. Furthermore, because the second outer groove wall of the upper cover is located in the first sealing groove of the lower cover, and the first inner groove wall of the lower cover is located in the second sealing groove, the path for water to enter the receiving cavity is lengthened, making it less likely for water to enter the interior of the charging pile. In addition, placing the first sealing ring in the second sealing groove prevents water from directly impacting the ring, thus improving its sealing effect.

[0028] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings.

[0054] The terminology used in the embodiments of this disclosure is for illustrative purposes only and is not intended to limit the disclosure.

[0055] A charging station is used to connect to an electric vehicle (EV) and charge it. In related technologies, the charging station includes a lower cover 1, an upper cover 2, a circuit device 4, and two cables 100. The lower cover 1 has a receiving cavity 10, the circuit device 4 is fixed to the receiving cavity, and the upper cover 2 is used to close the receiving cavity 10. One of the two cables 100 is an inlet cable, and the other is an outlet cable. A portion of the cable 100 extends into the receiving cavity 10 and is electrically connected to the circuit device 4. The portion of the inlet cable outside the receiving cavity 10 is used for electrical connection to the power grid, and the portion of the outlet cable outside the receiving cavity 10 is used for electrical connection to the charging gun, allowing the charging gun to draw power from the power grid through the charging station and then charge the EV. The side wall of the lower cover 1 of the charging station also has a hanging hole 200, into which the charging gun can be inserted when the charging station is not in use.

[0056] However, in related technologies, water can easily enter between the upper cover 2 and the lower cover 1 of the charging pile, damaging the circuit components 4. Therefore, a waterproof design is required for the receiving cavity 10. In related technologies, the upper cover 2 is typically flat, and a sealing ring between the upper cover 2 and the lower cover 1 can provide a waterproof effect. However, when the upper cover 2 has an irregular shape (such as an arc shape), the sealing ring can also be squeezed into an irregular shape between the upper cover 2 and the lower cover 1. Under the elastic force of the sealing ring itself, it can easily detach from the receiving groove of the upper or lower cover, leading to waterproofing failure.

[0057] In view of the above-mentioned technical problems, this disclosure provides a charging pile, such as Figures 1-4 As shown ( Figure 3 for Figure 4 (A partially enlarged view), the charging pile includes a lower cover 1, an upper cover 2, a first sealing ring 3, and circuit components 4. The lower cover 1 includes a bottom wall 1a and multiple side walls. One end of the multiple side walls is connected to the bottom wall 1a, and the multiple side walls and the bottom wall 1a form a receiving cavity 10 for accommodating the circuit components 4. The other end of the multiple side walls includes an annular first sealing groove 11, which includes a first outer groove wall 111 and a first inner groove wall 112. Figure 5 and Figure 6 As shown ( Figure 6 for Figure 5 (Partial enlarged view) The bottom end of the first outer groove wall 111 includes a drain hole 1110, which communicates with the first sealing groove 11. The upper cover 2 includes an annular second sealing groove 21, which includes a second outer groove wall 211 and a second inner groove wall 212. The upper cover 2 closes the receiving cavity 10, and the second outer groove wall 211 extends into the first sealing groove 11, the first inner groove wall 112 extends into the second sealing groove 21, and the first sealing ring 3 is sandwiched between the bottom of the first inner groove wall 112 and the second sealing groove 21.

[0058] Among them, the charging pile can be a wall-mounted charging pile, that is, the bottom wall of the lower cover 1 is fixed to the wall, and the upper cover 2 faces away from the wall.

[0059] Circuit device 4 may include a power supply module, a controller, and protection circuits, etc.

[0060] The technical solution provided in this disclosure embodiment allows water to enter the first sealing groove 11. Under the influence of gravity, the water in the first sealing groove 11 flows downwards along the first sealing groove 11, thereby flowing towards the drain hole 110 and then towards the outside of the charging pile. Figure 6The dashed arrows indicate the flow path of water in the first sealing groove 11. Furthermore, since the second outer groove wall 211 of the upper cover 2 is located in the first sealing groove 11 of the lower cover 1, and the first inner groove wall 112 of the lower cover 1 is located in the second sealing groove 21, the path for water to enter the receiving cavity 10 is lengthened, making it less likely for water to enter the interior of the charging pile. In addition, placing the first sealing ring 3 in the second sealing groove 21 can prevent water from directly impacting the first sealing ring 3, which helps improve the sealing effect of the first sealing ring 3.

[0061] In some examples, such as Figure 5 , Figure 7 and Figure 8 As shown, the multiple sidewalls include an upper sidewall 101, a lower sidewall 102, a left sidewall 103, and a right sidewall 104. The projections of the first end face 101a of the upper sidewall 101 and the second end face 102a of the lower sidewall 102 along the height direction are arc-shaped, wherein the first end face 101a and the second end face 102a are respectively the ends of the upper sidewall 101 and the lower sidewall 102 away from the bottom wall 1a.

[0062] The left side wall 103 and the right side wall 104 can be arranged symmetrically.

[0063] In some examples, such as Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, the distance between the first end face 101a and the bottom wall 1a gradually decreases from the middle to both ends, and the distance between the second end face 102a and the bottom wall 1a gradually decreases from the middle to both ends. Along the direction from high to low, the distance between the third end face 103a of the left side wall 103 and the bottom wall 1a, and the distance between the fourth end face 104a of the right side wall 104 and the bottom wall 1a, first increase and then decrease. The third end face 103a and the fourth end face 104a are the ends of the left side wall 103 and the right side wall 104 that are furthest from the bottom wall 1a, respectively.

[0064] In some examples, such as Figure 9 As shown, let L1 be the distance from the top of the fourth end face 104a to the bottom wall, and L2 be the distance from the bottom of the fourth end face 104a to the bottom wall. Then L1 > L2.

[0065] In some examples, such as Figure 9 As shown, let D1 be the distance from the midpoint of the first end face 101a to the bottom wall 1a, and D2 be the distance from the midpoint of the second end face 102a to the bottom wall. Then D2 > D1.

[0066] In some examples, such as Figure 5 , Figure 7 , Figure 8 and Figure 9As shown, along the direction from high to low, the third end face 103a of the left side wall 103 successively includes a first segment 1031 and a second segment 1032, and the fourth end face 104a of the right side wall 104 successively includes a third segment 1041 and a fourth segment 1042. Along the direction from high to low, the distances between the first segment 1031 and the bottom wall 1a, and between the third segment 1041 and the bottom wall 1a, gradually increase, while the distances between the second segment 1032 and the bottom wall 1a, and between the fourth segment 1042 and the bottom wall 1a, gradually decrease. The third end face 103a and the fourth end face 104a are the ends of the left side wall 103 and the right side wall 104 that are furthest from the bottom wall 1a, respectively.

[0067] Along the direction from high to low, the distance between the first segment 1031 and the third segment 1041 gradually increases, while the distance between the second segment 1032 and the fourth segment 1042 gradually decreases. The projections of the second segment 1032, the second end face 102a, and the fourth segment 1042 along the height direction form a W shape.

[0068] Correspondingly, the shapes of the upper cover 2, the bracket 6, and the curved glass 7 are approximately the same as the shape of the end face of the lower cover 1 away from the bottom wall 1a. This makes the charging pile more aesthetically pleasing overall. It is understood that the upper cover 2 is arc-shaped and protrudes in a direction away from the lower cover 1. This also increases the volume of the receiving cavity 10, facilitating the arrangement of the circuit components 4 within the receiving cavity 10.

[0069] Of course, the end faces of the multiple side walls of the lower cover 1 that are away from the bottom wall 1a can also be straight, and this embodiment does not specifically limit this.

[0070] In some examples, the width of the drain hole 1110 is 1mm-4mm. This facilitates the drainage of water in the first sealing groove 11 through the drain hole 1110. If the diameter of the drain hole 1110 is too small, the drainage speed will be too slow, resulting in excessive water accumulation in the first sealing groove 11, which may then easily enter the receiving cavity 10. If the diameter of the drain hole 1110 is too large, foreign objects from outside the charging pile may enter the first sealing groove 11 through the drain hole 1110, easily causing blockage and hindering the drainage of water from the first sealing groove 11.

[0071] The shape of the drain hole 1110 is not specifically limited in this embodiment. The shape of the drain hole 1110 can be circular, rectangular, elliptical, etc.

[0072] In some examples, such as Figure 4As shown, the width of the first outer groove wall 111 is greater than the width of the second outer groove wall 211, meaning that the end of the first outer groove wall 111 furthest from the bottom wall 1a protrudes relative to the top cover 2. This allows the first sealing groove 11 to be deeper, and the second outer groove wall 211 to be entirely located inside the first sealing groove 11. Furthermore, it results in a longer path for water outside the charging pile to flow from the first sealing groove 11 to the second sealing groove 21, making it less likely for water to enter the interior of the receiving cavity 10, thus further improving the waterproof performance of the charging pile.

[0073] In some examples, such as Figure 2 and Figure 3 As shown, the charging station also includes a display module 5, a bracket 6, a curved glass 7, and a second sealing ring 8. The top cover 2, bracket 6, and curved glass 7 are stacked together. The top cover 2 has a first opening 22 through which the display module 5 passes. The bracket 6 has a second opening 61 surrounding the display module 5. Users can view the estimated completion time, the amount of electricity charged, or make payments via QR code on the display module 5 through the curved glass 7. To prevent water from entering the charging station through the first opening 22, a waterproof design is required for the first opening 22.

[0074] Therefore, as Figure 10 As shown ( Figure 10 for Figure 3 (Partial enlarged view) The upper cover 2 has an annular third sealing groove 23 on the side opposite to the lower cover 1, and the third sealing groove 23 surrounds the first opening 22. The bracket 6 has an annular first rib 62, and the first rib 62 surrounds the second opening 61. The first rib 62 extends into the third sealing groove 23, and the second sealing ring 8 is sandwiched between the first rib 62 and the bottom of the third sealing groove 23. In this way, even if water enters between the bracket 6 and the upper cover 2, the third sealing groove 23 and the second sealing ring 8 can block the water, thereby preventing water from flowing into the first opening 22 and thus preventing damage to the display module 5.

[0075] The bracket 6 and the curved glass 7 can be connected together with adhesive. For example, adhesive is applied to the surface of the bracket 6, and then the curved glass 7 is attached to the bracket 6. Therefore, there are no gaps between the bracket 6 and the curved glass 7, making it difficult for water to enter between the bracket 6 and the curved glass 7, thereby preventing water from flowing through the gap between the bracket 6 and the curved glass 7 to the first opening 22.

[0076] In some examples, such as Figure 4As shown, the upper cover 2 has a fourth sealing groove 24 on the side opposite to the lower cover 1. A second sealing groove 21 surrounds the fourth sealing groove 24, and the fourth sealing groove 24 surrounds the third sealing groove 23. The bracket 6 has an annular second rib 63 located within the fourth sealing groove 24. Thus, even if water enters between the upper cover 2 and the curved glass 7, the fourth sealing groove 24 can still block the water, requiring it to travel a longer path to enter between the bracket 6 and the upper cover 2, thereby further improving the waterproof performance between the bracket 6 and the upper cover 2. The second rib 63 can be a sidewall of the bracket 6.

[0077] For example, a sealing ring can also be provided between the bottom wall of the fourth sealing groove 24 and the second protruding rib 63 to further improve the waterproof performance between the bracket 6 and the top cover 2.

[0078] In related technologies, a transparent sealing cover is typically placed between the display module 5 and the curved glass 7, covering the outside of the display module to seal it. However, this creates a gap between the display module 5 and the curved glass 7, resulting in poor display quality. Light is easily reflected multiple times between the display module 5 and the curved glass 7, causing image distortion or glare. In this embodiment, because the bracket 6 and the upper cover 2 have good waterproofing, water is less likely to flow into the display module 5, thus eliminating the need for a sealing cover. Therefore, no gap is required between the display module 5 and the curved glass 7, and the side of the display module 5 facing away from the lower cover 1 is in contact with the curved glass 7.

[0079] The integration of the display module 5 with the curved glass 7 also facilitates user interaction with the display module 5, such as selecting the charging duration on the display module 5.

[0080] In some examples, the curved glass 7 is made of tempered glass. In related technologies, the curved glass of charging piles is usually made of injection-molded materials, such as acrylic. Compared with injection-molded materials, tempered glass has higher light transmittance, which helps users see the content of the display module 5 more clearly.

[0081] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
