[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] like Figure 1 As shown, this embodiment provides a charging device, which includes a charging connector 100, a charging cable, and a charging base 200, wherein one end of the charging cable is connected to the charging connector 100 and the other end is connected to the charging base 200. Through the above connection, fast charging of new energy electric vehicles can be achieved.

[0036] In addition, such as Figure 3 As shown in this embodiment, the charging dock 200 is a fast and slow charging integrated structure as well as an AC / DC integrated structure, which can further expand the applicability of the charging device, thereby providing charging services for more types of batteries and improving the user experience.

[0037] In addition, such as Figure 2 As shown, in this embodiment, the charging connector 100 is equipped with a secondary locking structure 110, which not only facilitates the subsequent installation of the charging connector 100, but also provides higher fixing strength, effectively preventing safety accidents caused by accidental detachment or poor contact during plugging and unplugging under load, thereby improving the reliability and safety of use.

[0038] However, existing charging cables, which are primarily made of copper wire harnesses, suffer from high cost and weight. Therefore, this embodiment also provides a charging cable, such as... Figure 1 As shown, the charging cable includes a cable 10 and a seal 20. The cable 10 includes a main cable 11 and a copper busbar 12. One end of the main cable 11 is connected to the charging connector 100, and the other end is connected to the charging base 200. The main cable 11 is made of aluminum material and its outer periphery is covered with an insulating component. At least one end of the main cable 11 is connected to the copper busbar 12. The seal 20 is sleeved at the connection between the main cable 11 and the copper busbar 12.

[0039] In the above structure, the main cable 11 is made of aluminum. Compared with copper cable bundles, aluminum cable bundles with the same relative overload capacity, the same diameter (both 120 square millimeters), and the same length can reduce weight by two-thirds (aluminum density is 2.7 g / cm³, copper density is 8.92 g / cm³). 3 Furthermore, aluminum is less expensive than copper, thus solving the problems of high weight and cost in existing technologies. In this embodiment, a sealing element 20 is wrapped around the connection between the main cable 11 and the copper busbar 12, which seals the connection and ensures a good and stable connection, thereby producing a good power supply effect.

[0040] It should be noted here that, to further ensure good charging performance, such as Figure 1 As shown, copper busbars 12 are provided at both ends of the main cable 11. Further, since the copper busbars 12 need to connect to the charging connector 100 and the charging base 200, in this embodiment, the copper busbars 12 are flexible (soft copper busbars). They are made of high-purity electrolytic copper, which is soft, easy to bend, and has good ductility. Therefore, they are suitable for occasions requiring frequent bending or deformation, thereby improving the application range and ease of use of the charging cable.

[0041] Specifically, both ends of the main cable 11 are welded to the copper busbar 12. This welded connection method further improves stability, making them less prone to breakage, thus extending service life and ensuring continuous power supply. It is worth noting that in this embodiment, the main cable 11 and the copper busbar 12 are connected by ultrasonic welding. Compared to laser welding, ultrasonic welding has advantages such as faster welding speed, lower energy consumption, higher weld strength, better conductivity, and no sparks, thereby further improving conductivity.

[0042] It is worth noting that in this embodiment, the sealing element 20 is a thermoplastic sleeve. After the main cable 11 is welded to the copper busbar 12, the thermoplastic sleeve is used for sealing and protection. The thermoplastic sleeve not only has excellent flame retardancy and insulation properties, but is also very flexible, with a low shrinkage temperature and a fast shrinkage speed. Therefore, after the thermoplastic sleeve is placed at the connection between the main cable 11 and the copper busbar 12, the thermoplastic sleeve can quickly shrink using the residual heat of the weld until it completely covers the weld. This method can better protect the weld and prevent it from being damaged or oxidized during use, thereby ensuring the stability of the charging effect.

[0043] In addition, a temperature sensor is installed inside the seal 20. The temperature sensor monitors the temperature of the solder joint in real time. When the temperature of the solder joint is too high, the temperature sensor will issue an alarm in time, and the user can quickly cut off the power to ensure the safety of use.

[0044] In addition, such as Figure 1 As shown, the main cable 11 can be bent at a preset angle. Due to the different positions of the charging connector 100 and the charging base 200, the main cable 11 can be bent at the actual angle, thereby improving the user experience and ease of use.

[0045] In summary, compared with existing technologies, the charging cable in this embodiment is not only lightweight and low-cost, but also offers high charging stability. Furthermore, the charging device in this embodiment is more convenient to use.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
