Description

Technical Field

[0001] This utility model relates to a charger, specifically a UK standard folding charger. Background Technology

[0002] As mobile phones and other consumer electronics become increasingly powerful, evolving from basic communication tools into multifunctional smart terminals integrating social networking, entertainment, and office work, users' reliance on these devices has skyrocketed. This has made the issue of battery life in mobile phones and other consumer electronics increasingly prominent. Portable chargers, as key devices for solving this battery life problem, are experiencing explosive market demand. Whether commuting, traveling, or engaging in outdoor activities, people expect to be able to recharge their mobile phones and other consumer electronics anytime, anywhere, ensuring they are always online. Most UK-standard chargers on the market have fixed prongs or only the GND pin is retractable; the other two conductive pins are fixed, making them inconvenient to carry when traveling. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a UK standard foldable charger to solve the problems existing in the background art.

[0004] This utility model of a UK standard folding charger is achieved through the following technical solution, including:

[0005] A charger front cover and a bottom cover assembly, wherein the bottom cover assembly is fixedly connected to the bottom of the charger front cover, and a folding plug assembly is provided inside the bottom cover assembly;

[0006] The folding pin assembly includes at least one GND PIN and at least one conductive PIN. By rotating the GND PIN, the conductive PIN can be driven to rotate from a folded state to an unfolded state or from an unfolded state back to a folded state, thereby realizing the folding and extension of the pin.

[0007] As a preferred technical solution, the bottom shell assembly includes a bottom shell body and a pressure plate, wherein the pressure plate is disposed above the bottom shell body;

[0008] The pressure plate is provided with a conductive spring that cooperates with the conductive end of the conductive PIN. When the conductive PIN is in the unfolded state, its conductive end contacts the conductive spring to achieve power supply connection.

[0009] As a preferred technical solution, the folding pin assembly further includes:

[0010] Shaft assembly, connecting rod,

[0011] The bottom of the main body of the bottom shell is provided with rotating grooves on both sides for rotating the conductive PIN, and a toggle groove is provided in the middle of the bottom. The GND PIN is rotatably set in the toggle groove through the rotating shaft assembly. The rotation direction of the GND PIN is opposite to the rotation direction of the conductive PIN.

[0012] The end of the rotating shaft assembly is provided with a first eccentric shaft, the rotating end of the conductive PIN is provided with a second eccentric shaft, and the two ends of the connecting rod are respectively hinged to the first eccentric shaft and the second eccentric shaft.

[0013] The connecting rod is provided with a clearance groove, and the rotating rod on the rotating shaft assembly is placed in the clearance groove so that when the GND PIN rotates, the conductive PIN is driven to rotate through the connecting rod.

[0014] As a preferred technical solution, the end of the rotating shaft assembly is provided with a first locking position, and the other end of the conductive PIN is provided with a second locking position;

[0015] A tension spring is connected between the first and second locking positions to keep the GND PIN and conductive PIN stable between the open and closed states, and to provide damping and shock absorption.

[0016] As a preferred technical solution, a decorative element is provided on the upper part of the charger casing.

[0017] The beneficial effects of this utility model are:

[0018] This invention overcomes the problem of existing UK standard plugs being fixed and non-foldable by designing the conductive pin as a foldable structure and driving the conductive pin to unfold or retract through the linkage of the GND pin. This effectively reduces the size of the charger, improves portability, and is especially suitable for business travel scenarios.

[0019] This invention allows for the simultaneous folding or unfolding of the conductive pin simply by moving the GND pin, resulting in smooth operation and avoiding the cumbersome multi-finger operation. It features a user-friendly mechanical linkage design.

[0020] This utility model adopts a mechanical transmission structure composed of an eccentric shaft and a connecting rod, which provides stable mechanical linkage while realizing the rotation of the conductive PIN. The structure responds accurately and is not easy to jam or misalign during operation.

[0021] This invention features a locking structure between the GND PIN and the conductive PIN, along with a tension spring. This structure provides appropriate resistance and elasticity during pin rotation, preventing the pin from suddenly popping out or rebounding, thus improving safety and comfort during use.

[0022] The conductive pin of this invention can reliably contact the conductive spring on the pressure plate when it is unfolded, forming a stable electrical contact path, which helps to improve power supply stability and prevent infrequent connections and unstable current.
