Description

Technical Field

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

[0002] Currently, most European standard charger plugs on the market use a fixed structure, meaning their prongs cannot be folded or stored. While this structure has advantages such as low manufacturing cost and simple design, it presents several inconveniences in actual use. On one hand, because the prongs are always exposed, users are prone to scratching their belongings or bending and deforming the prongs during daily carrying, which is detrimental to portability. On the other hand, in crowded socket environments, especially in multi-outlet power strips, the fixed prongs can easily interfere with surrounding plugs or walls, causing problems with proper insertion and severely impacting the user experience.

[0003] To address these issues, some technical solutions attempt to design the plugs as detachable or rotatable structures to achieve a certain degree of storage functionality. However, such structures typically involve complex mechanical mechanisms or multi-part assembly, resulting in high manufacturing costs, insufficient reliability, and a lack of smooth and natural feel for users during operation, making them difficult to promote and use. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a novel European standard foldable charger with a simpler structure, easier folding and storage, and a better user experience, thus enhancing the user's experience when traveling, storing, or in confined spaces.

[0005] This utility model is achieved through the following technical solution: a novel European standard folding charger, comprising:

[0006] A housing having a rotating cavity formed thereon;

[0007] A plug housing with European standard pins installed at its upper end; a connecting rod is fixedly provided on the plug housing; the plug housing is rotatably installed in the rotating cavity via the connecting rod.

[0008] The damping shaft is fixedly positioned inside the housing on both sides and is connected and assembled to one rotating end of the connecting rod.

[0009] The plug housing can rotate 90 degrees back and forth within the rotating cavity.

[0010] As a preferred technical solution, the housing includes an upper shell, a lower shell, and a middle shell, with the upper shell and the lower shell assembled on both sides of the middle shell.

[0011] As a preferred technical solution, a pivot mounting position is formed at the splicing position of the upper shell and the lower shell, and a rotating protrusion is formed on both sides of the connecting rod, and the rotating protrusion is rotatably supported in the pivot mounting position.

[0012] As a preferred technical solution, a snap-fit ​​limiting groove is also formed on the splicing surface of the upper shell and the lower shell, and a limiting buckle is formed at one end of the damping shaft, and the limiting buckle is limited and snapped into the snap-fit ​​limiting groove.

[0013] As a preferred technical solution, the plug housing and the connecting rod are ultrasonically welded.

[0014] The beneficial effects of this utility model are: by setting a damping rotation shaft between the bottom shell and the connecting rod, this utility model enables the pins to fold and rotate within the range of -90° to +90°, so that the pins can be stored inside the shell when not in use, effectively reducing the volume and making it convenient for users to carry and store.

[0015] The foldable plug structure allows for flexible angle adjustment based on the socket location, making it suitable for various scenarios with compact spaces or densely packed sockets. It solves the problem of traditional fixed plugs being unable to be inserted due to space constraints.

[0016] The damping rotation axis provides moderate rotational resistance during the folding or unfolding of the pins, which not only prevents the pins from swinging automatically and improves structural stability, but also provides users with a smooth and responsive operating feel, enhancing the overall user experience.

[0017] This utility model adopts a simple mechanism such as a connecting rod and a damping rotating shaft, which facilitates mass production and assembly of the product while ensuring the realization of its functions, and has good prospects for industrial application. Attached Figure Description

[0024] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0025] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0026] like Figures 1-3 As shown in the figure, this utility model discloses a novel European standard folding charger. The structure and operation of the charger will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0027] This utility model includes a housing 1, a plug housing 3, and a damping rotating shaft 5. The housing 1 is an integral support structure with a rotating cavity for accommodating the rotation of the plug housing 3. In this embodiment, the housing 1 preferably consists of an upper shell, a lower shell, and a middle shell. The upper and lower shells are respectively fixed to both sides of the middle shell by assembly, forming a closed and stable spatial structure, while providing the necessary space and support for the rotation of the internal plug housing 3.

[0028] The plug housing 3 is disposed within the rotating cavity of the housing 1, and a European standard plug 4 is fixedly installed on its upper end to provide an output port for the electrical connection of the charger. A connecting rod 2 structure is provided on one side of the plug housing 3. One end of the connecting rod 2 is fixed to the plug housing 3 and a stable connection is achieved by means of ultrasonic welding or other methods. The other end extends and is installed in the rotating structure within the rotating cavity to achieve a rotatable connection between the plug housing 3 and the housing 1.

[0029] To enable smooth and controlled rotation of the plug housing 3 within the housing 1, a limiting support structure, namely a damping shaft 5, is installed on both sides of the interior of the housing 1. The damping shaft 5 is fixed to both sides of the interior of the housing 1 by a limiting method and forms a rotatable connection with one end of the connecting rod 2. The damping shaft 5 not only supports the plug housing 3 to rotate back and forth 90 degrees, but also provides moderate resistance during rotation, thereby preventing the plug housing 3 from swinging due to gravity or external forces, enhancing its stability and safety at various angles.

[0030] During actual assembly, a pivot mounting position is formed at the splicing point of the upper and lower shells to accommodate the rotating protrusions 21 at both ends of the connecting rod 2. Rotating protrusions 21 are formed on both sides of the connecting rod 2, and these protrusions 21 can be inserted into and rotatably supported within the pivot mounting position, realizing the rotation function of the plug shell 3 relative to the shell 1. Furthermore, to further enhance assembly reliability and limiting effect, a locking groove 52 is also provided on the splicing surface of the upper and lower shells. One end of the damping pivot 5 forms a limiting buckle 51, which is inserted into and locked into the limiting groove during assembly, effectively preventing the damping pivot 5 from dislodging and ensuring the stability and service life of the overall structure.

[0031] During use, users can manually rotate the plug housing 3 to move the European standard plug pins 4 from the retracted state to the usable state. The plug housing 3 can reciprocate within a range of -90° to +90° within the rotating cavity, meeting the plugging and unplugging needs of sockets in different directions. After use, the plug pins can be rotated back into the housing 1 for storage, avoiding the inconvenience and potential damage caused by exposed plug pins. The entire rotation process provides moderate tactile feedback under the action of the damping shaft 5, enhancing the user experience.

[0032] Through the above structural design, this utility model not only achieves the convenient function of foldable and retractable plugs, but also takes into account structural stability, smooth operation and simple assembly process. It is suitable for portable designs of various European standard plug chargers and has good industrial application prospects.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
