Description

Technical Field

[0001] This invention relates to the field of charging pile technology, specifically to a waterproof top structure and a charging pile having the same. Background Technology

[0002] Charging stations are fixed to the ground or walls and installed in public buildings or parking lots. They can charge various models of electric vehicles according to different voltage levels.

[0003] Existing charging piles typically have a metal casing. Because metal is difficult to design and manufacture in a complex way, the structure is generally quite simple. For waterproofing, waterproof foam is installed on the door panel, and waterproofing is achieved through the pressure between the door panel and the lock.

[0004] When using injection-molded shells, the aforementioned pressure-sealing waterproof design is rarely adopted because injection-molded products cannot withstand the pressure of door panels or the cost is too high. Currently, injection-molded structures conventionally use glue application or adhesive sealing strips. However, both of these methods require precise installation and functional testing to ensure no leakage occurs, which seriously affects mass production. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of poor waterproof effect of injection molded shells in the prior art, thereby providing a top waterproof structure suitable for injection molded shells and a charging pile having the same.

[0006] To solve the above-mentioned technical problems, the present invention provides a top waterproof structure, comprising: an injection-molded shell, the injection-molded shell including a front shell and a rear shell, with a joint formed between the front shell and the rear shell; a sealing strip, the sealing strip being disposed at the joint between the front shell and the rear shell; a water guide channel, the water guide channel being located inside the injection-molded shell and directly below the joint formed above the front shell and the rear shell, and the bottom of the injection-molded shell having a water guide hole for water to flow out through the water guide channel, the water guide channel receiving water leaking from the joint above the front shell and the rear shell, and the water being discharged outward through the water guide hole.

[0007] Preferably, a groove for embedding a sealing strip is provided on the contact surface between the front housing and the rear housing, and an insert plate adapted to the shape of the groove is provided on the rear housing; or a groove for embedding a sealing strip is provided on the contact surface between the rear housing and the front housing, and an insert plate adapted to the shape of the groove is provided on the front housing.

[0008] The sealing strip is set in the groove. After the front and rear housings are closed, the insert plate is inserted into the groove and abuts against the sealing strip.

[0009] Preferably, the front housing is provided with a screw post, which is located inside the groove and the insert plate. The rear housing is provided with a through hole opposite to the screw post. Fasteners are connected to the screw post through the through hole to connect the front housing and the rear housing.

[0010] Preferably, the rear housing is provided with a screw post, which is located inside the groove and the insert plate. The front housing is provided with a through hole opposite to the screw post. Fasteners are connected to the screw post through the through hole to connect the front housing and the rear housing.

[0011] Preferably, the sealing strip includes an mounting portion and a snap-fit ​​portion, with the snap-fit ​​portion connecting to both sides of the mounting portion to form a lip.

[0012] Preferably, the mounting part is disposed in the groove and cooperates with the insert plate, and the snap-fit ​​part is wrapped around both sides of the insert plate. The snap-fit ​​part is used to seal the gaps between the insert plate and the inner and outer side walls of the groove, respectively.

[0013] Preferably, the upper surface of the water guide channel is provided with reinforcing ribs, which are provided on one side of the joint formed between the upper part of the front shell and the rear shell.

[0014] Preferably, the reinforcing rib extends continuously along the joint formed between the upper part of the front shell and the upper part of the rear shell.

[0015] Preferably, the water guide channel is provided with a through hole, which is located on the side of the reinforcing rib away from the joint.

[0016] In addition, a charging station is provided, which includes the top waterproof structure of any of the above solutions.

[0017] The technical solution of this invention has the following advantages:

[0018] 1. The top waterproof structure provided by the present invention has a sealing strip at the joint between the front and rear shells and a water guide groove below the joint. The double waterproofing through the sealing strip and the water guide groove can greatly improve the waterproofing efficiency, and there is no need to apply a large pressure between the front and rear shells of the outer shell, thus meeting the usage requirements of the injection molded shell.

[0019] 2. The top waterproof structure provided by the present invention improves the overall waterproof effect of the structure by setting an insert plate and a groove at the joint of the front and rear shells. The insert plate presses the sealing strip to embed the sealing strip into the groove. Furthermore, the water guide channel is set directly below the joint. When the sealing effect of the sealing strip deteriorates, water droplets will drip into the water guide channel and flow from the water guide channel to the water guide hole at the bottom of the charging pile for discharge, ensuring that the electronic equipment inside the charging pile always has a dry environment.

[0020] 3. The top waterproof structure provided by the present invention connects the front and rear shells with fasteners, ensuring the stability of the connection between the shells and ensuring that the insert plate always compresses the sealing strip, thus ensuring the sealing of the product seams.

[0033] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] The top waterproof structure provided in this embodiment is used to seal the joint between the front and rear housings of the charging pile, which can save time in housing installation.

[0035] like Figure 1 , 6As shown, the top waterproof structure provided in this embodiment includes: an injection-molded shell, a sealing strip 3, and a water guide channel 4. The injection-molded shell includes a front shell 1 and a rear shell 2, with a seam formed between the front shell 1 and the rear shell 2; the sealing strip 3 is disposed at the seam between the front shell 1 and the rear shell 2; the water guide channel 4 is located inside the injection-molded shell and directly below the seam formed between the front shell 1 and the rear shell 2; the bottom of the injection-molded shell is provided with a water guide hole 5, which is used to drain water passing through the water guide channel 4; the water guide channel 4 is used to collect water leaking from the seam above the front shell 1 and the rear shell 2 and to discharge the water outward through the water guide hole 5. A sealing strip 3 is installed at the joint between the front housing 1 and the rear housing 2. Due to the sealing strip 3, rainwater and other liquids cannot enter the interior of the housing at this joint. However, after prolonged use, the sealing effect of the sealing strip 3 deteriorates. At this point, rainwater can enter the water channel 4 inside the housing through the joint. The water channel 4 is located directly below the joint. After flowing into the water channel 4, the liquid flows out through the water channel holes 5 at the bottom of the housing along both sides due to gravity. The sealing strip 3 is snapped into the joint of the housing. During installation, the sealing strip 3 only needs to be embedded into the groove 6 and fixed with bolts to complete the installation process, which greatly improves production efficiency and reduces the installation difficulty of the injection-molded housing.

[0036] like Figure 5 , 6 As shown, in the top waterproof structure provided in this embodiment, a groove 6 for embedding a sealing strip 3 is provided on the contact surface between the front housing 1 and the rear housing 2, and an insert plate 7 adapted to the shape of the groove 6 is provided on the rear housing 2; or, a groove 6 for embedding a sealing strip 3 is provided on the contact surface between the rear housing 2 and the front housing 1, and an insert plate 7 adapted to the shape of the groove 6 is provided on the front housing 1; the sealing strip 3 is disposed in the groove 6. After the front housing 1 and the rear housing 2 are closed, the insert plate 7 is inserted into the groove 6 and abuts against the sealing strip 3. In this embodiment, the insert plate 7 is located on the front housing 1, and the groove 6 is located on the rear housing 2. The insert plate 7 fixes the sealing strip 3 into the groove 6 by pressing it, thus forming a sealing effect. In addition, as an alternative embodiment, insert plates 7 are provided on both the front housing 1 and the rear housing 2, and the insert plates 7 on both sides press the sealing strip 3 to form a sealing effect.

[0037] like Figure 2 , 6As shown, in the top waterproof structure provided in this embodiment, a screw post 8 is provided on the front housing 1, and the screw post 8 is located inside the groove 6 and the insert plate 7. A through hole 9 corresponding to the screw post 8 is provided on the rear housing 2. Fasteners 10 pass through the through hole 9 and connect to the screw post 8 to connect the front housing 1 and the rear housing 2. In this embodiment, the screw post 8 is provided on the front housing 1, and the through hole 9 corresponding to the screw post 8 is provided on the rear housing 2; the screw post 8 can also be provided on the rear housing 2, the purpose of which is to fix the front and rear housings 2 so that the insert plate 7 can squeeze the sealing strip 3 to achieve a better sealing effect. The screw post 8 is located inside the housing, and the through hole 9 on the rear housing 2 corresponds to the screw post 8. By fastening the front and rear housings 2, the fasteners 10 can pass through the through hole 9 and connect to the screw post 8; a reinforcing rib 13 is provided between the screw post 8 and the housing, the function of the reinforcing rib 13 is to ensure the structural strength of the screw post 8. In this embodiment, the fastener 10 is a bolt, which is used to fix the front and rear housings 2. Alternatively, as an alternative embodiment, the front and rear housings 2 can be snapped together using a snap-fit ​​mechanism.

[0038] like Figure 4 As shown, in the top waterproof structure provided in this embodiment, the sealing strip 3 includes an mounting portion 11 and a snap-fit ​​portion 12. The snap-fit ​​portion 12 is connected to both sides of the mounting portion 11 to form lips. The mounting portion 11 is disposed in the groove 6 and cooperates with the insert plate 7. The snap-fit ​​portion 12 wraps around both sides of the insert plate 7 and is used to seal the gaps between the insert plate 7 and the inner and outer side walls of the groove 6, respectively. In this embodiment, the mounting portion 11 is circular, and the snap-fit ​​portion 12 is disposed on both sides of the mounting portion 11. The insert plate 7 abuts against the mounting portion 11 through the lips on both sides and presses against the mounting portion 11. Alternatively, as an alternative embodiment, the sealing strip 3 can be elongated with an opening on one side. The insert plate 7 is inserted into the opening and abuts against the groove 6 to form a seal.

[0039] like Figure 3 As shown, in the top waterproof structure provided in this embodiment, a reinforcing rib 13 is provided on the upper surface of the water guide channel 4. The reinforcing rib 13 is provided on one side of the joint formed between the front housing 1 and the rear housing 2. The reinforcing rib 13 is provided on the upper surface of the water guide channel 4 because the housing and the water guide channel 4 are plastic products. The reinforcing rib 13 is provided on one side of the joint. When liquid drips naturally from the joint, it will fall into one side of the reinforcing rib 13, allowing the liquid to flow to the bottom of the water guide channel 4 as quickly as possible. In addition, as an alternative embodiment, the reinforcing rib 13 can be provided directly below the joint.

[0040] like Figure 2As shown, in the top waterproof structure provided in this embodiment, the water channel 4 is provided with a through hole 14, which is located on the side of the reinforcing rib 13 away from the joint. The through hole 14 is used to connect certain wires. The through hole 14 being located on the side away from the joint allows liquid to drip naturally onto the side of the reinforcing rib 13 away from the through hole 14, preventing the liquid from corroding the wires. Alternatively, as an alternative embodiment, the through hole 14 can be located on the side of the reinforcing rib 13 closer to the joint, with waterproof tape wrapped around the wires.

[0041] Installation method of the top waterproof structure: Insert the water guide groove 4 into any housing, place the mounting part 11 of the sealing strip 3 into the groove 6 of the front housing 1, abut the insert plate 7 on the rear housing 2 against the snap-fit ​​part 12, fasten the front and rear housings 2 together, and use fasteners 10 to install into the screw hole post 8 to fix the front and rear housings 2.

[0042] In addition, such as Figure 1 As shown, a charging pile is also provided. The top of the charging pile adopts the aforementioned waterproof structure. In addition, electronic devices can be placed inside the cavity formed by the water guide channel 4 of the charging pile. Sealing strips 3 are provided at the seams around the perimeter of the housing. The sealing strips 3 are pressed into the grooves 6 on the other side of the housing by the insert plate 7 on one side of the housing, forming a sealing effect and waterproofing the internal electronic devices of the charging pile.

[0043] The working principle of the charging pile: When liquid enters the joint between the housings, the sealing strip 3 forms a seal in the groove 6 under the action of the insert plate 7. Therefore, the sealing strip 3 blocks the liquid from flowing into the housing and affecting the operation of the electrical equipment. However, after prolonged use, the sealing strip 3 will expand and harden, resulting in a decrease in the sealing effect. At this time, liquid will flow into the housing. After the liquid passes through the sealing strip 3 and flows into the housing, it naturally drips into the water guide trough 4. The liquid flows to both sides from the water guide trough 4 and flows out from the water guide hole 5 at the bottom.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
