This connection method is not only complex and costly, but the copper cables also have limited current carrying capacity, making them incapable of meeting high-power requirements. Utility Model Content

[0030] See also Figures 1 to 3 This embodiment provides a novel AC / DC integrated charging station, including a housing 1, and a DC charging station 2 and an AC charging station 3 spaced apart on the housing 1. A DC power terminal 4 is provided in the DC charging station 2, and the rear cover of the DC charging station 2 is provided with a rear upper cover 5.

One end of the conductive bar 6 is connected to the fixing portion 402 via a locking member 7, and the other end extends outside the rear upper cover 5. By connecting the conductive bus 6 with the fixed portion 402 of the DC power terminal 4, the traditional copper cable crimping process is replaced, which not only simplifies the assembly steps in the production process and reduces manual operations, but also reduces the demand for materials (such as copper cables), thereby effectively reducing production costs; in addition, the setting of the conductive bus 6 and the fixed portion 402 can carry a larger current, so the new AC / DC integrated charging stand can better meet the use requirements of high-power charging equipment, such as electric vehicle fast charging scenarios, and improve charging efficiency and user experience.

When the rear upper cover 5 is placed on the rear end of the DC charging station 2 and a certain amount of pressure is applied, the first latches 201 snap into the first notches 501, thereby achieving a secure fastening between the rear upper cover 5 and the DC charging station 2. The provision of the first latches 201 and the first notches 501 simplifies the assembly process, allowing the user to complete the assembly of the rear upper cover 5 without the use of additional tools or fasteners.

[0032] See also Figure 2 、 Figure 3 In one embodiment, a first sealing ring 8 is provided between the rear upper cover 5 and the DC charging base 2. The first sealing ring 8 can effectively isolate external impurities such as moisture and dust from entering the DC charging base 2, protect the internal electrical components from damage, extend the service life, and ensure that the new AC / DC integrated charging base meets the IP67 requirements.

[0033] See also Figures 1 to 3 In one embodiment, a mounting hole 502 is provided on one side of the rear upper cover 5 corresponding to the fixing portion 402. A side cover 9 is provided above the mounting hole 502. A first fixing hole 4021 is provided along the mounting hole 502 of the fixing portion 402, which cooperates with the locking member 7. A second fixing hole 601 is provided along the mounting hole 502 on the end of the conductive bar 6 adjacent to the fixing portion 402, which cooperates with the locking member 7. The first fixing hole 4021 and the second fixing hole 601 completely overlap along the mounting hole 502. The locking member 7, in conjunction with the first fixing hole 4021 and the second fixing hole 601, secures the DC power terminal 4 to the conductive bar 6, simplifying the installation process and improving the reliability and stability of the connection. The provision of the mounting hole 502 provides a passage for the installation of the locking member 7, making it easier for the user to insert the locking member 7 into the rear upper cover 5, thereby securing the DC power terminal 4 to the conductive bar 6. The side cover 9 is provided to facilitate the user to lock the DC power terminal 4 and the conductive bar 6 and then cover the mounting hole 502 , thereby protecting the internal locking member 7 and the connection part from the influence of the external environment.

[0034] See also Figure 2 、 Figure 3 In one embodiment, the locking member 7 is a screw, and the first fixing hole 4021 and the second fixing hole 601 are screw holes. Using a screwdriver, the user can easily screw the screws into the first fixing hole 4021 and the second fixing hole 601. The combination of the screws and the screw holes provides reliable fastening force, ensuring a secure connection between the DC power terminal 4 and the conductive bar 6. This connection method is not only simple and reliable, but also low-cost and easy to maintain.

[0035] See also Figure 2 、 Figure 3 In one embodiment, a second sealing ring 10 for sealing the mounting hole 502 is provided in the side cover 9. The second sealing ring 10 can effectively prevent external moisture, dust and other impurities from entering the interior of the rear cover 5, protect the internal electrical components from damage, extend the service life, and ensure that the new AC / DC integrated charging stand meets the IP67 requirements.

[0036] See also Figure 3 In one embodiment, the outer wall of the mounting hole 502 is circumferentially provided with a plurality of second snaps 503, and the side cover 9 is circumferentially provided with a plurality of second snap notches 901 that mate with the second snaps 503. When the side cover 9 is placed at the end of the mounting hole 502 and a certain amount of pressure is applied, the second snaps 503 snap into the second snap notches 901, thereby achieving a secure engagement between the side cover 9 and the mounting hole 502. The provision of the second snaps 503 and the second snap notches 901 simplifies the assembly process, allowing the user to complete the assembly of the side cover 9 without the use of additional tools or fasteners.

[0037] See also Figure 1 、 Figure 3 In one embodiment, the rear upper cover 5 has an opening 504 for the conductive bar 6 to pass through. A conductive bar cover 11 is installed above the opening 504 and fits over the conductive bar 6. A third sealing ring 12 is installed within the conductive bar cover 11 to seal the gap between the conductive bar 6 and the rear upper cover 5. The third sealing ring 12 fits over the conductive bar 6. By providing the opening 504 in the rear upper cover 5, and providing the conductive bar cover 11 and the third sealing ring 12, the conductive bar 6 maintains a good seal while extending from the rear upper cover 5, ensuring that the new AC / DC integrated charging station meets IP67 requirements.

When the conductive busbar cover 11 is placed at the end of the opening 504 and pressure is applied, the third latches 505 snap into the third latches 1101, thereby securing the conductive busbar cover 11 to the opening 504. The provision of the third latches 505 and third latches 1101 simplifies the assembly process, allowing the user to assemble the conductive busbar cover 11 without the use of additional tools or fasteners.

[0039] In one embodiment, the conductive bar 6 is made of copper or aluminum. Aluminum is more cost-effective than copper. This is because aluminum reserves are relatively abundant, and mining and processing costs are relatively low. Therefore, without compromising overall performance, choosing aluminum as the material for the conductive bar 6 can significantly reduce production costs and improve the product's market competitiveness. It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications are intended to fall within the scope of protection of the appended claims of this utility model.
