Description

Technical Field

[0001] This utility model relates to the field of charging pile equipment technology, and in particular to a charging module and a charging pile. Background Technology

[0002] Currently, most charging modules on the market use forced air cooling for heat dissipation. The environment in which charging stations are located is also quite harsh. When the fan blows heat off the components during operation, it can easily bring dust and moisture from the air into the charging module. Therefore, if the charging module is not protected, it will lead to corrosion of the components and affect the lifespan of the charging module.

[0003] Existing technologies propose a method to improve the protection level by applying a full potting technique to the components of the charging module. However, the full potting process is relatively complex and has high manufacturing costs. At the same time, the potting adhesive may also cause some interference to the circuit, causing the components of the charging module to fail, which is also very inconvenient for after-sales repair.

[0004] Therefore, how to provide a charging module with a high level of protection and low cost is an urgent problem to be solved. Utility Model Content

[0032] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0033] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0034] The charging module proposed in this utility model includes heat dissipation components and other features that should be present in the charging module assembly of existing charging piles.

[0035] In order to improve the protection level of charging modules, a technical solution of potting all components of the charging module has been proposed. However, the potting process is relatively complex and the manufacturing cost is high. At the same time, potting may also cause some interference to the circuit, causing the components of the charging module to fail, which is also very inconvenient for after-sales repair.

[0036] Therefore, in one embodiment, reference is made to the appendix. Figure 1 A charging module with a high protection level and low manufacturing cost is proposed, including: a chassis 100 and a printed circuit board 200 disposed in the chassis 100;

[0037] The front side of the printed circuit board 200 is provided with multiple components 300, and a protective cover 400 is attached to the front side of the printed circuit board 200. All components 300 on the front side of the printed circuit board 200 are matched and penetrate the protective cover 400.

[0038] A first sealing element 500 is provided between the back side of the printed circuit board 200 and the inner side wall of the corresponding chassis 100.

[0039] It should be noted that the first seal 500 is in close contact with the back of the printed circuit board 200 and the inner wall of the corresponding chassis 100.

[0040] Therefore, the back of the first sealing element 500 is first fixed and tightly attached to the inner wall of the chassis 100. Then, the back of the printed circuit board 200 is tightly attached to the front of the first sealing element 500. This ensures the seal between the back of the printed circuit board 200 and the corresponding inner wall of the chassis 100, preventing external dust and moisture from entering the back of the printed circuit board 200, thus preventing corrosion of the surface mount components on the back of the printed circuit board 200 and ensuring the service life of the charging module. Then, the protective cover 400 is fitted to the front of the printed circuit board 200, and the protective cover 400 is fitted to the bottom of all the components 300 on the front of the printed circuit board 200. This ensures the seal between the front of the printed circuit board 200 and the components 300, preventing external dust and moisture from entering the connection area between the pins of the printed circuit board 200 and the components 300, thus preventing corrosion of the front of the printed circuit board 200 and the components 300, and further improving the service life of the charging module.

[0041] Therefore, by providing a protective cover 400 and a first sealing element 500 on the front and back sides of the printed circuit board 200 respectively, when the heat dissipation component cools the charging module, the dust, water vapor and other pollutants brought in by the heat dissipation component are blocked by the protective cover 400 and the first sealing element 500, preventing the dust, water vapor and other pollutants from corroding the printed circuit board 200, thereby improving the protection level of the charging module. At the same time, the protective cover 400 and the first sealing element 500 are easy to manufacture and have low manufacturing cost. Moreover, compared with the technical solution of fully potting the components of the charging module, the charging module of this application is easy to disassemble after sales and will not interfere with the printed circuit board 200.

[0042] It should be noted that the components 300 proposed in this embodiment include, but are not limited to, transformers, inductors, heat sinks, capacitors, etc.

[0043] In one embodiment, refer to Appendix Figure 1 A second sealing element 600 is provided between the bottom of the protective cover 400 and all the components 300 that penetrate the protective cover 400. The second sealing element 600 cooperates with the corresponding protective cover 400 to form a sealing structure. The sealing structure is used to protect the connection area between the pin of the corresponding component 300 and the printed circuit board 200.

[0044] In this way, when the protective cover 400 is fitted to the front of the printed circuit board 200, a second seal 600 is filled between the protective cover 400 and the bottom of all components 300 penetrating the protective cover 400, so as to further improve the sealing performance of the front of the printed circuit board 200 and the components 300, effectively preventing dust, moisture and other pollutants in the outside air from entering the connection area between the pins of the printed circuit board 200 and the components 300, thereby preventing corrosion of the front of the printed circuit board 200 and the components 300, and further improving the service life of the charging module.

[0045] Therefore, this utility model improves the protection level of the charging module by providing a protective cover 400 and a second sealing element 600 on the front side of the printed circuit board 200 and a first sealing element 500 on the back side of the printed circuit board 200. At the same time, the protective cover 400, the first sealing element 500 and the second sealing element 600 are easy to manufacture and have low manufacturing costs.

[0046] The protective cover 400 is attached to the printed circuit board 200 by adhesive, snap-fit, or bolt connection. Of course, the connection structure between the protective cover 400 and the printed circuit board 200 can also be other connection structures that are easy to disassemble, and is not limited here.

[0047] For ease of understanding, the connection structure between the protective cover 400 and the printed circuit board 200 in this embodiment is preferably a bolt connection.

[0048] The chassis 100 is integrally formed from a metal sheet through a bending process.

[0049] It should be noted that the metal sheet proposed in this embodiment is a steel sheet, aluminum alloy sheet, stainless steel sheet or other highly corrosion-resistant metal, and is not limited here.

[0050] Furthermore, the thickness of the chassis 100 is preferably in the range of 1mm-2mm.

[0051] The protective cover 400 is made of high-temperature resistant and flame-retardant plastic material through injection molding.

[0052] It should be noted that the thickness of the protective cover 400 proposed in this embodiment is preferably in the range of 1mm-3mm.

[0053] The first seal 500 and the second seal 600 are both made of flame-retardant and high-temperature resistant materials.

[0054] It should be noted that the first seal 500 is preferably a high-temperature resistant flame-retardant foam, and the second seal 600 is preferably silicone rubber.

[0055] In another embodiment, refer to the appendix Figure 2 A second sealing element 600 is provided between the back side of the printed circuit board 200 and the corresponding inner side wall of the chassis 100.

[0056] A first sealing element 500 is provided between the protective cover 400 and the bottom of all the components 300 that penetrate the protective cover 400. The first sealing element 500 cooperates with the corresponding protective cover 400 to form a sealing structure. The sealing structure is used to protect the connection area between the corresponding component 300 pin and the printed circuit board 200.

[0057] In this way, the back of the second sealing element 600 is first fixed and tightly attached to the inner wall of the chassis 100, and then the back of the printed circuit board 200 is tightly attached to the front of the second sealing element 600. This ensures a seal between the back of the printed circuit board 200 and the corresponding inner wall of the chassis 100, preventing dust, moisture, and other contaminants from the outside air from entering the back of the printed circuit board 200, thus preventing corrosion of the surface-mount components on the back of the printed circuit board 200 and ensuring the lifespan of the charging module. Then, the protective cover 400 is fitted and matched to the front of the printed circuit board 200. The protective cover 400 is matched and fitted to all components 300 on the front side of the printed circuit board 200. Then, a first sealing element 500 is filled between the protective cover 400 and the bottom of all components 300 penetrating the protective cover 400, thereby ensuring the sealing of the front side of the printed circuit board 200 and the components 300, preventing dust, moisture and other pollutants in the outside air from entering the connection area between the pins of the printed circuit board 200 and the components 300 and the front side of the printed circuit board 200, thereby preventing corrosion of the front side of the printed circuit board 200 and the components 300, and thus improving the service life of the charging module.

[0061] A second seal 600 is filled between the protective cover 400 and the bottom of all the components 300 that penetrate the protective cover 400.

[0062] In another embodiment, the present invention also proposes a charging pile, which includes the charging module described above.

[0063] In this way, the back of the first sealing element 500 is first fixed and tightly attached to the inner wall of the chassis 100, and then the back of the printed circuit board 200 is tightly attached to the front of the first sealing element 500. This ensures a seal between the back of the printed circuit board 200 and the corresponding inner wall of the chassis 100, preventing dust, moisture, and other contaminants from the outside air from entering the back of the printed circuit board 200. This prevents corrosion of the surface-mount components on the back of the printed circuit board 200, ensuring the lifespan of the charging module and charging pile. Then, the protective cover 400 is fitted and matched to the front of the printed circuit board 200. The protective cover 400 is matched and adhered to all components 300 on the front side of the printed circuit board 200. Then, a second seal 600 is filled between the protective cover 400 and the bottom of all components 300 penetrating the protective cover 400, thereby ensuring the sealing of the front side of the printed circuit board 200 and the components 300, preventing dust, moisture and other pollutants in the outside air from entering the connection area between the pins of the printed circuit board 200 and the components 300 and the front side of the printed circuit board 200, thereby preventing corrosion of the front side of the printed circuit board 200 and the components 300, and thus improving the service life of the charging module and the charging pile.
