[0001] This utility model relates to the field of charging device technology, and more particularly to a flat rotary charger that achieves rotatable adjustment and stable positioning of the plug through a special pivot and positioning structure. Background Technology

[0002] Chargers are indispensable electronic accessories in modern daily life. Whether it's a mobile phone, tablet, or other portable device, they all need to be powered by a charger to ensure continuous operation. Traditional chargers mostly use a fixed plug structure, which can achieve basic power transmission functions, but they are prone to interference with other objects during use. For example, when used in space-constrained areas, they often interfere with walls, furniture, or other surrounding objects, leading to problems such as difficulty in plugging in and inconvenience in use, thus affecting the convenience and flexibility of the charger.

[0003] Therefore, enabling charger plugs to adjust their angle relative to the charger body has become a key focus in product development. However, the design of such rotating structures must not only consider the flexibility of angle adjustment and the continuity of electrical connections, but also ensure sufficient mechanical stability of the plug after positioning to prevent difficulties in insertion and removal or structural damage due to shaking. Thus, providing a charger with a rotating plug function while ensuring structural durability and reliable positioning has become a long-term goal for related industries.

[0004] In view of this, the team of this utility model, based on years of experience and expertise in related fields, conceived and proposed a flat rotary charger to effectively address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a flat rotary charger, which allows the plug to adjust its angle relative to the body through the coordinated configuration of the plug and the guide hole to meet the usage requirements of different installation environments, while maintaining the stability of electrical conduction. Through the cooperation of the positioning bead and the positioning recess, it achieves precise positioning and stable stopping after rotation, avoiding loosening or shaking.

[0006] To achieve the above objectives, this utility model provides a flat rotary charger, comprising: a housing assembly having an accommodating space; a printed circuit board assembly disposed in the accommodating space, the printed circuit board assembly having at least one charging female connector; a cover covering the open end of the housing assembly to close it, the cover covering the opposite end of the housing assembly having a first protrusion and a plurality of positioning recesses, the first protrusion having a first through hole and a guide hole, the first through hole extending from one end of the first protrusion to the other end, the guide hole being located on the side of the first protrusion, the positioning recesses being arranged around the first protrusion; and a rotary plug pivotally mounted on the cover and rotatable relative to the housing assembly, comprising: a plug housing; and two pins disposed on the plug. On one side of the outer casing: a plug cover, one end of which is fitted over the open end of the plug casing to close it; the plug cover has a second protrusion with a second through hole, the second through hole extending from one end of the second protrusion to the other end; wherein the second protrusion is fitted over the first protrusion; at least one positioning bead is disposed on the plug cover; a plug is disposed on the side of the second protrusion with one end passing through the guide hole; and two electronic wires, one end of which passes through the inside of the plug casing and is electrically connected to the two pins respectively, and the other end passes through the second through hole and the first through hole into the cover assembly and is then electrically connected to the printed circuit board assembly; wherein, when the rotary plug is rotated, the plug moves along the guide hole, and the positioning bead engages or disengages from either of the positioning recesses.

[0007] Preferably, the second protrusion has a mounting hole on its side for mounting the plug.

[0008] Preferably, the plug cover has at least one mounting recess for mounting the positioning bead.

[0009] Preferably, the positioning bead is mounted on the mounting recess via a carrier member, the positioning bead being located at one end of the carrier member and being able to retract slightly inward in response to force.

Detailed Implementation

[0024] To enable those skilled in the art to clearly understand the technical content of this utility model, the following description is provided in conjunction with the accompanying drawings. The figures shown are merely illustrative examples to facilitate understanding of the proposed embodiments of this utility model and are not intended to limit the scope of protection of this utility model. In actual application, adjustments may be made flexibly according to product requirements.

[0025] Please see Figures 1A to 3 The figures shown are exploded view, exploded view from another perspective, structural assembly diagram (I), (II), and partial structural cross-sectional view of a preferred embodiment of the present invention. The present invention provides a flat rotary charger 1, comprising a housing assembly 10, a printed circuit board assembly 11, a cover 12, and a rotary plug 13.

[0026] The cover assembly 10 has an accommodating space 101, and preferably, the aspect ratio of the cover assembly 10 is, for example, 2.5:1 to 3.5:1. The printed circuit board assembly 11 is disposed within the accommodating space 101 and is provided with at least one charging female connector 111 for connecting external electronic devices. The cover 12 is fitted over the open end of the cover assembly 10 to close it. The cover 12 is designed to have a first protrusion 121 at its opposite end covering the cover assembly 10 and a plurality of positioning recesses 122 surrounding the first protrusion 121. The first protrusion 121 has a first through hole 1211, which extends from one end of the first protrusion 121 to the other end, and a guide hole 1212 is formed on the side of the first protrusion 121. Preferably, the guide hole 1212 can be arc-shaped, which can limit the angle and prevent the rotary plug 13 from rotating in circles or causing abnormal movements that could affect electrical conductivity. It also allows the plug 135 to slide smoothly, improving the stability and smoothness of the rotation operation. The rotary plug 13 is pivotally connected to the cover 12 and can rotate relative to the cover assembly 10. The rotary plug 13 includes a plug housing 131, two pins 132, a plug cover 133, at least one positioning bead 134, a plug 135, and two electronic wires 136. The two pins 132 are located on one side of the plug housing 131 for electrical connection to an external socket. The plug cover 133 is fitted over the open end of the plug housing 131 to close it. The plug cover 133 has a second protrusion 1331 with a second through hole 1332, which extends from one end of the second protrusion 1331 to the other end. The second protrusion 1331 is fitted over the first protrusion 121. The positioning bead 134 is provided on the plug cover 133 to engage with the positioning recesses 122 to achieve a rotational positioning function. The insert 135 is provided on the second protrusion 1331, with one end passing through the guide hole 1212 of the first protrusion 121 to slide along the guide hole 1212. Preferably, the insert 135 can be, for example, a cylindrical structure. One end of the two electronic wires 136 passes through the inside of the plug housing 131 and is electrically connected to the two pins 132 respectively. The other end passes through the second through hole 1332 and the first through hole 1211 into the housing assembly 10 and is then electrically connected to the printed circuit board assembly 11. When the rotary plug 13 is rotated, the insert 135 moves along the guide hole 1212 to achieve stable guiding rotation performance. At the same time, the positioning bead 134 engages or disengages from any of the positioning recesses 122 to achieve rotational positioning. To illustrate the rotational operation state of the rotary plug 13, [details omitted]. Figure 2A and Figure 2BIn the figure, the plug housing 131 is represented by a chain line, while the component structure located inside the plug housing 131 is represented by a solid line; in addition, the cover assembly 10 is also represented by a solid line; to clearly show the state in which the second protrusion 1331 is fitted onto the first protrusion 121 and the guide hole 1212 is located inside the second protrusion 1331, the guide hole 1212 and the portion of the plug 135 that passes through the guide hole 1212 are represented by dashed lines.

[0027] Accordingly, this invention enables smooth guidance and stable support when the rotary plug 13 rotates relative to the housing assembly 10, through the sliding engagement of the insert 135 and the guide hole 1212, preventing offset or wobbling. Simultaneously, the structure of the insert 135 and the guide hole 1212 disperses friction during rotation, reducing wear on the protruding structure and improving durability. This structure also simplifies the assembly process; the insert 135 can be quickly positioned and pivoted by aligning with the guide hole 1212. Furthermore, this invention achieves multi-angle positioning through the engagement of the positioning bead 134 and the positioning recesses 122, ensuring the rotary plug 13 is securely fixed at different rotational positions. This design not only prevents the plug from loosening or shifting due to external forces during use but also effectively solves the problem of traditional fixed plugs easily interfering with walls, furniture, or other obstacles in space-constrained environments, thereby improving the convenience and reliability of the device in practical applications.

[0028] Preferably, when the guide hole 1212 is arc-shaped and its central angle is approximately 180 degrees, it can effectively further limit the rotation range of the rotary plug 13, so that it can meet the user's needs when adjusting the angle, while avoiding excessive rotation that could cause interference with walls, furniture, or other objects, and reducing the possibility of pulling or abrasion on the electronic wire 136. Figure 2B The image shows the rotary plug 13. Figure 2A The state is counterclockwise, that is, the state after rotating upwards in the diagram. This rotating plug 13 can also be... Figure 2A The state is clockwise, which means rotating downwards in the diagram.

[0029] Considering structural assembly and rotational stability requirements, the second protrusion 1331 can have a mounting hole 1333, which is located on the side of the second protrusion 1331 to accommodate the insert 135. In this way, the insert 135 can be reliably fixed to the second protrusion 1331 and precisely pass through the guide hole 1212 of the first protrusion 121. Simultaneously, this mounting hole 1333 design simplifies the assembly process between the insert 135 and the second protrusion 1331, improving assembly efficiency.

[0030] Furthermore, in one embodiment, the plug cover 133 is provided with at least one mounting recess 1334 for mounting the positioning bead 134. Accordingly, the positioning bead 134 can be stably disposed in the mounting recess 1334 and cooperate with the positioning holes 122 to achieve stable positioning of the rotary plug 13 at multiple angles.

[0031] Furthermore, the positioning bead 134 can be assembled into the mounting recess 1334 via a support member 1341. The positioning bead 134 is located at one end of the support member 1341 and can slightly retract inward in response to force. More specifically, with this structure, when the rotary plug 13 is rotated, the positioning bead 134, during its movement from one positioning recess 122 to another, will retract inward due to the pressure of the cover 12's plane, allowing for smooth sliding. When it reaches the next positioning recess 122, it will automatically reset and embed itself into the positioning recess 122 due to the loss of pressure. This design not only makes the rotary plug 13 easier and more natural to operate, but also maintains precise positioning of the rotation angle, preventing wobbling or loosening, further improving the durability and ease of use of the rotary plug 13.

[0032] Preferably, there are two positioning beads 134 and two mounting recesses 1334, which are symmetrically arranged on opposite sides of the second protrusion 1331. In this way, during operation of the rotary plug 13, the two positioning beads 134 can work simultaneously with the positioning recesses 122 to provide a more balanced and stable rotational positioning force, preventing excessive force on one side from causing the rotary plug 13 to wobble or tilt. The symmetrical arrangement also enhances the accuracy of multi-angle positioning, ensuring that the rotary plug 13 maintains good mechanical stability and electrical connection reliability at different angles.

[0033] Considering that the rotary plug 13 needs to withstand repeated rotation operations and external forces over a long period, the first protrusion 121 can be made of plastic. Plastic has good elasticity and wear resistance, effectively absorbing friction and impact generated during rotation, reducing structural wear and extending service life. At the same time, plastic reduces overall weight and improves ease of use. Furthermore, using plastic also helps reduce manufacturing costs and processing complexity.

[0034] Furthermore, in one embodiment, the enclosure assembly 10 includes a housing 102 and a faceplate 103. The housing 102 is open at both ends, with one end closed by the cover 12 and the other end closed by the faceplate 103. The faceplate 103 has at least one opening 1031, which corresponds to the charging female connector 111. This design effectively protects the internal printed circuit board assembly 11 and related electronic components from dust, foreign objects, or external impacts. Simultaneously, the position of the opening 1031 of the faceplate 103 corresponding to the charging female connector 111 allows for convenient and safe insertion and removal of external electronic devices, balancing protection and ease of use. Moreover, this structure allows for assembly, maintenance, or replacement of internal components by simply removing the faceplate 103, thereby improving the convenience of modular assembly and subsequent maintenance.

[0035] Please continue to refer to this as well. Figure 4 and 5 The diagram shows a structural schematic of another preferred embodiment of the present invention and a structural schematic of yet another preferred embodiment. The charging female connector 111 of the printed circuit board assembly 11 can be of type A or type C, and the number can be set to two or more. In this case, the number of openings 1031 is also correspondingly set to two or more. For example, when the number of charging female connectors 111 is two, the charging female connector type 111 can both be type C, such as... Figure 4 As shown; or when the number of the charging female connectors 111 is three, one of the charging female connectors 111 is of type A, and the other two are of type C, such as Figure 5 As shown. Accordingly, by configuring multiple sets of charging female sockets 111 of different types, this utility model can simultaneously support the charging needs of multiple electronic devices, improving the versatility and convenience of the device; users can select the corresponding socket for connection according to different device interfaces, without the need for additional adapters or charger replacements, increasing practicality and operational efficiency.

[0036] In summary, the flat rotary charger of this utility model, through the sleeve structure of the first and second protrusions, combined with the guide hole and the sliding fit of the plug, enables the rotary plug to have a smooth guiding and stable rotation effect during angle adjustment. The synergistic effect of the positioning bead and the positioning recesses ensures accurate positioning at multiple angles, smooth operation, and prevents the rotary plug from shaking or loosening, thus improving safety and durability. Furthermore, the arc design and approximately 180-degree central angle of the guide hole not only limit the rotation range to avoid interference with surrounding objects but also reduce the pulling or wear of electronic wires, improving durability. The mounting hole of the plug, fixed to the second protrusion, simplifies assembly and provides excellent structural stability. The mounting recess structure allows the positioning bead to be stably set in the plug cover. The carrier design allows the positioning bead to slightly retract and return to its original position during sliding, further improving the smoothness and accuracy of rotation operation. The symmetrical design of the positioning bead provides a more stable positioning effect. Furthermore, using plastic to make the first protruding post reduces weight and cost; the double-enclosed casing structure effectively protects the internal circuit board assembly and electronic components from external forces or foreign objects, and improves the convenience of maintenance and parts replacement. With multiple different types of charging female connectors, users can simultaneously support the charging needs of various electronic devices, increasing versatility and ease of operation. In summary, this invention combines structural stability, smooth operation, and excellent durability, and is suitable for space-constrained environments, significantly improving the limitations of traditional fixed chargers.

[0037] The above description is merely a preferred embodiment of the present utility model and should not be used to limit the scope of the present utility model. Therefore, any textual changes or modifications made without departing from the equivalent scope of the present utility model should still be covered within the protection scope of the present utility model.
