Description

Technical Field

[0001] The utility model belongs to the technical field of chargers, and particularly relates to an integrated telescopic power adapter structure. Background Art

[0002] The charger provides stable voltage and current to electronic products such as mobile phones and computers for charging through an external power supply, so that the electronic products can continue to be used. With the improvement of living standards, more and more people own electronic products with different functions, such as mobile phones, tablets, smart bracelets, and so on. Moreover, the speed of product update and iteration of electronic products is getting faster and faster, and the charging interfaces of different brands are not necessarily the same. Therefore, a charger with a single interface cannot adapt to different types of electronic products, and it is inconvenient to carry multiple chargers when traveling.

[0003] For example, the Chinese patent document with the publication number CN217956734U discloses a portable multi-functional charger, which includes a control board installed in a housing. The control board is electrically connected to a power plug and is respectively connected to a first interface, a second interface, and a third interface through three wires. The housing also installs a first one-way stretching automatic retractable wire reel, a second one-way stretching automatic retractable wire reel, and a third one-way stretching automatic retractable wire reel for telescoping the interfaces. The outer surface of the housing also installs a first button, a second button, and a third button to control the telescoping of the first interface, the second interface, and the third interface respectively. A storage groove is opened on one side of the housing, and the power plug is set as a foldable power plug and is installed in the storage groove; the housing also has a first interface slot, a second interface slot, and a third interface slot for storing the first interface, the second interface, and the third interface respectively. The first interface, the second interface, and the third interface are taken out from the first interface slot, the second interface slot, and the third interface slot, and then pulled out to be connected to the charging device.

[0004] In the technical solution of the above patent document, the charger is provided with three interfaces, which solves the charging requirements of different types of interfaces. The three interfaces are a combination of a Micro USB interface, a Lightning interface, and a Type-C interface, all of which are wired charging interfaces. The Micro USB interface can charge old Android phones, the Lightning interface can charge old versions of Apple phones and tablets, and the Type-C interface can charge Android phones, tablets, new versions of Apple phones, Apple tablets, and some brand smart bracelets on the market. This charger can charge different brands and types of electronic products, but there are still some electronic products on the market that can only be charged wirelessly. For example, an Apple Watch needs a special charging dial or a magnetic charger for charging, which is not compatible with the existing wired charger interfaces, resulting in users still needing to use additional chargers. This makes users need to use multiple chargers at home, in the office, or when traveling, on business trips, increasing the difficulty of storage and carrying. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an integrated telescopic power adapter structure, which solves the problem that the existing multi-interface charger does not have a wireless charger, so that users still need to configure an additional charger, affecting the use experience.

[0007] Further, the number of the winding devices is three groups and they are arranged in parallel in the installation cavity; the connectors connected to two of the charging wires are both Type-C connectors.

[0008] Further, the other connectors connected to the charging wires are a Type-C connector and a Lightning connector respectively.

[0009] Further, a positioning cavity is recessed inward on the adjacent side of the housing where the wire passing hole is provided, for positioning and accommodating the wireless charging connector; a second magnetic part is further arranged in the positioning cavity, and the second magnetic part and the first magnetic part attract each other to fix the wireless charging connector in the positioning cavity.

[0010] Further, a wire groove is also arranged on the outside of the housing. One end of the wire groove extends to the positioning cavity, and the other end extends to the wire passing hole, for avoiding the charging wire connecting the wireless charging connector.

[0011] Further, a card slot is arranged on one side of the housing where the wire passing hole is provided.
