Description

Technical Field

[0001] This utility model relates to a folding charging head, specifically to a novel ultra-thin folding charging head structure. Background Technology

[0002] Currently, with the widespread use of mobile electronic devices and the increasing demand for portability, the design of charging heads is developing towards miniaturization, lightweighting, and high efficiency. Ultra-thin foldable charging heads are favored by the market due to their small footprint and portability. However, existing ultra-thin foldable charging heads still have many shortcomings in their structural design and urgently need improvement.

[0003] Most foldable chargers on the market currently use a pressure plate and screws to fix the foldable plug structure. While this method achieves the folding function of the plug, it presents the following problems in the design of ultra-thin chargers:

[0004] Because the pressure plate requires additional installation space, in ultra-thin structures, the pressure plate area is prone to interference with other components on the PCB board, thereby reducing the space utilization of the PCB board and making it difficult to further reduce the thickness of the charging head.

[0005] Using a pressure plate and screws for fixing requires additional parts, which not only increases manufacturing costs but also increases assembly difficulty and reduces production efficiency.

[0006] Traditional methods require additional mechanical fastening steps, such as tightening screws, which increases the time required for manual assembly and is not conducive to large-scale production. Utility Model Content

[0007] To address the aforementioned issues, this invention provides a novel ultra-thin folding charging head structure. By optimizing the connection between the AC insert and the rotating shaft, and employing a snap-fit ​​fixing method combined with wave soldering technology using spring contacts, the structure of pressure plate + screws is avoided, reducing the number of parts, improving assembly efficiency, and simultaneously increasing the utilization rate of the PCB board surface, resulting in a thinner, lighter, and more reliable charging head.

[0008] This utility model is achieved through the following technical solution: a novel ultra-thin folding charging head structure, comprising:

[0009] A housing, in which a PCBA board is fixedly installed;

[0010] Two spring clips are provided, which are respectively mounted on the PCBA board;

[0011] An AC plug is fixedly mounted on a rotating shaft. Rotating buckles are provided on both sides of the rotating shaft. The AC plug is in conductive contact with the spring contact.

[0012] The mounting base is provided for each AC plug. One side of the mounting base is provided with a rotating shaft mounting position, and the other side of the mounting base is provided with a plug slot. One end of the AC plug is rotatably installed in the plug slot and the other end extends into the rotating shaft mounting position.

[0013] The mounting base is provided with a rotating shaft groove corresponding to the position of the rotating buckle, and the rotating buckle is rotatably installed in the rotating shaft groove.

[0014] As a preferred technical solution, a shaft support groove is provided in the shaft mounting position, and the rotating shaft is rotatably installed into the shaft support groove.

[0015] As a preferred technical solution, a conductive contact portion with an outer diameter larger than the rotating shaft is respectively provided at both ends of the rotating shaft corresponding to the position of the spring piece. An arc-shaped protrusion is provided on the conductive contact portion, and an arc-shaped positioning groove is also provided on the bottom surface of the rotating shaft mounting position corresponding to the position of the arc-shaped protrusion. The arc-shaped protrusion is positioned in the arc-shaped positioning groove.

[0016] As a preferred technical solution, the rotating shaft is installed in a position that communicates with the insert slot, and the installation position of the rotating shaft is opposite to the opening direction of the insert slot.

[0017] As a preferred technical solution, the housing includes a bottom shell and a top shell, which are fixedly assembled with each other.

[0018] As a preferred technical solution, the spring is fixed to the PCBA board by wave soldering.

[0019] The beneficial effects of this utility model are: This utility model adopts the snap-fit ​​fixing method of AC plug and rotating shaft, which avoids the use of pressure plate and screw in traditional folding plug structure, thereby reducing the stacking thickness of components and making the overall charging head lighter and thinner.

[0020] Compared to the traditional pressure plate and screw fixing method, this utility model achieves foldable installation of AC plugs by using a snap-fit ​​and rotating shaft slot, and uses wave soldering process to fix the spring to the PCB board, avoiding the cumbersome assembly steps of screw fixing, thereby significantly improving production efficiency and reducing labor and equipment costs.

[0028] 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.

[0029] 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.

[0030] like Figures 1-4 As shown, this utility model provides a novel ultra-thin foldable charging head structure. The charging head includes a housing, and a PCBA board 3 is fixedly installed inside the housing. The PCBA board 3 serves as the core circuit carrier of the charging head, undertaking power conversion and control functions to ensure the normal operation of the device.

[0031] The shell consists of a bottom shell 2 and a front shell 1. The bottom shell 2 and the front shell 1 are fixedly connected by snaps or screws to form a closed structure, which ensures the safety and stability of the internal components and improves the mechanical strength and durability of the overall structure.

[0032] Two spring clips 5 are installed on the PCBA board 3. The spring clips 5 are fixed to the PCBA board 3 by wave soldering. This fixing method can effectively improve the soldering quality and ensure that the spring clips 5 will not fall off due to vibration or mechanical stress during long-term use.

[0033] Meanwhile, the spring 5, as a conductive connector of the AC plug 4, can provide stable electrical contact when the AC plug 4 is unfolded and disconnect the circuit when the plug is folded, ensuring a safe and reliable user experience.

[0034] The AC plug 4 is a key component connecting the charging head to an external power source. It is fixedly mounted on the rotating shaft and foldable via the rotating latch 7. The rotating shaft is located at the base of the AC plug 4, allowing the AC plug 4 to rotate around the shaft to complete the folding and unfolding actions. Rotating latches 7 are located on both sides of the rotating shaft, and these latches 7 can be inserted into the rotating shaft slots 8 on the mounting base 9, thereby ensuring stable positioning of the rotating shaft during folding and unfolding, preventing loosening or displacement.

[0035] Mounting base 9 is provided for each AC connector 4 and supports both the AC connector 4 and the rotating shaft. One side of mounting base 9 has a rotating shaft mounting position, and the other side has a connector slot 81. One end of the AC connector 4 is rotatably mounted in the connector slot 81, and this end also extends into the rotating shaft mounting position. This allows the AC connector 4 to rotate smoothly along the rotating shaft when folded and unfolded, avoiding jamming or misalignment, while ensuring the stability of the connector and the reliability of the electrical connection during operation.

[0036] To further improve the durability and reliability of the charging head, a rotating shaft support groove 11 is provided in the rotating shaft mounting position, and the rotating shaft can be rotatably installed into the rotating shaft support groove 11 during assembly. In addition, a conductive contact part 6 is provided at each end of the rotating shaft at the position corresponding to the spring piece 5. The outer diameter of the conductive contact part 6 is larger than that of the rotating shaft, thereby ensuring that the electrical plug can make tight contact with the spring piece 5 when unfolded, so as to achieve a reliable electrical connection.

[0037] The conductive contact part 6 is also provided with an arc-shaped protrusion, and the bottom surface of the rotating shaft mounting position is provided with an arc-shaped positioning groove 10 at the corresponding position. The arc-shaped protrusion can be embedded into the arc-shaped positioning groove 10, so that the AC plug 4 can be stably positioned when folded or unfolded to a specific position, preventing the plug from loosening or shifting due to external force, and ensuring safety and stability during use.

[0038] Furthermore, the hinge mounting position communicates with the insert slot 81, but its opening direction is opposite to that of the insert slot 81. This structural design optimizes the folding space, allowing the AC plug 4 to fit snugly inside the housing after folding, effectively reducing the overall thickness of the charging head and achieving an ultra-thin design. This eliminates the need for a pressure plate, improving portability and aesthetics. Simultaneously, this structure provides greater support when the plug is unfolded, preventing it from wobbling or being damaged due to uneven force during use.

[0039] This invention optimizes the fit between the AC connector 4, spring 5, rotating shaft, and mounting base 9, resulting in an ultra-thin folding charging head with a simple structure, small thickness, and high assembly efficiency. Compared to the traditional folding structure that uses a pressure plate and screws for fixing, this invention eliminates the pressure plate and screw design, reducing the number of parts, lowering manufacturing costs, and significantly improving assembly efficiency. It also avoids interference between the pressure plate area and the PCB board, improving PCB board utilization and making the internal structure of the charging head more compact and rational.

[0040] Through the above technical solution, this utility model ensures the ultra-thin design of the charging head while taking into account the reliability of the electrical connection, the stability of the structure, and the economy of production, and has high market application value.

[0041] 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.
