[0040] Charger, as the essential accessories of electronic equipment, its design evolves with the change of user demand. The traditional charger is fixed and cannot be folded, which not only occupies a large space, but also increases the inconvenience of carrying. To solve this problem, foldable chargers appear in the market, but the existing design often fixes the plug assembly and the plug base, which limits its flexibility and expandability.

[0041] The utility model provides a plug assembly, through the innovative plug assembly and plug base clamping design, not only realize the flexible folding of charger, also improved its modularization, expandability and maintenance convenience.

[0042] Please refer to Figures 1 to 6 In an embodiment of the utility model, the plug assembly 100 includes plug shell 110, plug 120 and pivot assembly 200, the plug 120 part is exposed to the plug shell 110, and the exposed part is used to be electrically connected with the jack of power socket;Pivot assembly 200 includes installation base 210 and the pivot module 240 arranged on installation base 210;Wherein, installation base 210 is used to be clamped and fixed with plug base 300, plug shell 110 is connected with the rotating shaft 243 of pivot module 240, and plug shell 110 can rotate relative to installation base 210 to make plug 120 close to or away from plug base 300.

[0043] The plug assembly 100 shown in the drawing is in the form required by European regulations. In other schemes, the plug assembly 100 can also be in the shape required by other regulations, such as Korean regulations, Brazilian regulations, Thai regulations, Indian regulations, etc.

[0044] In the technical scheme of the utility model, the installation base 210 of the pivot assembly 200 is clamped and fixed with the plug base 300, which simplifies the assembly process of the charger. At the same time, it also ensures the foldable function of the plug assembly 100. The plug shell 110 can rotate relative to the installation base 210 through the pivot module 240, so that the plug 120 is close to or away from the plug base 300, thereby realizing the folding function of the charger. The folded charger is smaller and more portable, and is convenient to carry and store. In addition, the plug assembly 100 can be assembled with different plug bases 300, realizing modular design. For example, manufacturers can design different shapes and functions of the base (with circuit board, etc. (not shown in the drawing)) according to customer needs, and the plug assembly 100 can be used as a universal standard module, which can provide users with more economical and practical charging solutions.

[0045] On the basis of realizing the flexible folding of the charger and improving its modularity, the plug assembly proposed by the utility model also improves the folding stability and service life of the product, and can customize the folding feeling and force.

[0046] In an embodiment, the rotating shaft module 240 is a shaft body arranged in the mounting base 210 and can rotate relative to the mounting base 210. The rotating shaft module 240 is pre-assembled with the plug housing 110. When subsequently assembled with the plug base 300 to form a charger, the manufacturer can select different specifications or functional shapes of the plug base 300 for assembly according to actual needs.

[0047] In an embodiment, the rotating shaft module 240 is configured as a damping rotating shaft. Compared with the rotating scheme of using a fixed shaft body and a shaft hole 221, the damping rotating shaft scheme improves the user experience. Specifically, the damping rotating shaft provides damping feeling for rotation through internal friction, which can ensure that the plug assembly 100 remains stable support and positioning when opening or folding relative to the plug base. This allows users to obtain a more stable use experience during use, avoiding the shaking or instability phenomenon caused by the lack of damping of the fixed shaft body. The damping rotating shaft allows users to freely adjust the rotation angle within a certain range and stay at any position as needed. This flexibility allows users to adjust the angle of the device according to actual use scenarios and habits, thereby obtaining a more comfortable use experience.

[0048] In addition, the damping rotating shaft scheme also improves the durability and service life of the rotating shaft module 240. Specifically, compared with the design of the fixed shaft body and the shaft hole 221, the internal friction of the damping rotating shaft can reduce the impact and friction during rotation, thereby reducing the degree of wear. In addition, the damping rotating shaft can absorb and disperse stress during rotation, thereby reducing the fatigue degree of the shaft body and the shaft hole 221. This helps to prolong the overall service life of the rotating shaft assembly 200 and reduce failures and damage caused by fatigue.

[0049] It should be noted that the design of the damping rotating shaft can also be customized according to different application scenarios and user needs. For example, the size of the damping force, the rotation range, and other parameters can be adjusted to meet the use needs of specific devices. This flexibility allows the damping rotating shaft to better adapt to diverse application scenarios.

[0050] Referring to Figure 5 and Figure 6 In the present scheme, the rotating shaft module 240 includes a shaft sleeve 241, a spring 242 arranged in the shaft sleeve 241, a rotating shaft 243 penetrating the spring 242, a first ratchet wheel 244 sleeved on the rotating shaft 243, and a second ratchet wheel 245 arranged in the shaft sleeve 241 and cooperating with the first ratchet wheel 244. The first ratchet wheel 244 cooperates with the second ratchet wheel 245 under the driving of the rotating shaft 243 at a first position and a second position, respectively. At the first position, the plug pin 120 is close to the plug base 300. At the second position, the plug pin 120 is away from the plug base 300.

[0051] In one aspect, the cooperation of the first ratchet wheel 244 and the second ratchet wheel 245 can ensure that the plug assembly 100 is stably supported and positioned when being opened or folded, ensuring the stable locking of the prongs 120 in the required position (i.e., in the direction of 0°-90°, perpendicular or parallel to the plug base), preventing the prongs 120 from moving accidentally due to external force during charging, and ensuring the reliability and safety of charging. In one aspect, the ratchet cooperation mechanism reduces wear by dispersing stress and reducing friction, and the spring 242 not only provides smooth transition during rotation, but also acts as a buffer when the prongs 120 are impacted by external force, protecting the rotating shaft module 240 from damage and prolonging the service life of the rotating shaft module 240. On the other hand, this scheme allows customization and modification according to user needs, such as adjusting the cooperation strength of the ratchet and the stiffness of the spring 242, to meet the individual needs of different users and provide users with a more comfortable user experience.

[0052] Referring to Figure 1 and Figure 2 , regarding the clamping and fixing form of the mounting base 210 and the plug base 300.

[0053] In one embodiment, the plug base 300 is designed with a buckle structure, and the mounting base 210 is designed with a corresponding buckle slot or buckle hole. Through the cooperation of the buckle and the buckle slot or buckle hole, the clamping and fixing of the mounting base 210 and the plug base 300 is achieved.

[0054] In one embodiment, the plug base 300 is provided with a pin hole, and the mounting base 210 is provided with a corresponding pin. Through the cooperation of the pin and the pin hole, the two are fixedly connected. Alternatively, the mounting base 210 is provided with an elastic card, and the plug base 300 is clamped between the cards through the elastic deformation of the cards.

[0055] Specifically, in order to facilitate assembly, the outer wall of the mounting base 210 is provided with a clamping portion 211 for clamping cooperation with the plug base 300. The clamping portion 211 can be provided on the outer wall of the mounting base 210. In order to facilitate production and manufacturing, the mounting base 210 includes a first housing 220 and a second housing 230 that are hingedly connected, and the clamping portion 211 is arranged on the opposite sides of the first housing 220 in the first direction. The design of the first housing 220 and the second housing 230 makes the assembly and disassembly process of the plug assembly 100 more simple and fast. By hingedly connecting the first housing 220 and the second housing 230, the overall structure of the mounting base 210 can be conveniently formed, and the assembly of the rotating shaft assembly 200 is also facilitated. The clamping portion 211 is arranged on the opposite sides of the first housing 220 in the first direction, which can make the clamping process of the mounting base 210 and the plug base 300 more smooth and stable. By clamping from both sides at the same time, the firm connection between the mounting base 210 and the plug base 300 can be ensured.

[0056] Specifically, in an embodiment, the clamping portion 211 is configured as a clamping protrusion; in an embodiment, the clamping portion 211 is configured as a clamping groove; in an embodiment, the clamping portion 211 is configured as a combination of a clamping protrusion and a clamping groove. In the scheme configured as a clamping protrusion, a clamping groove for clamping the clamping protrusion is provided on the plug base 300; similarly, in the scheme configured as a clamping groove, a clamping protrusion for clamping the clamping groove is provided on the plug base 300.

[0057] In a specific scheme, the clamping groove or the clamping protrusion is provided with a plurality of clamping grooves or clamping protrusions in the width direction of the first shell 220 to provide a more stable fixing effect; in other schemes, a plurality of clamping protrusions and clamping grooves can also be arranged in the first direction.

[0058] It should be noted that the first direction is the same as the axial direction of the rotating shaft module 240, and the first direction is also the length direction of the first shell 220.

[0059] In a specific scheme, the rotating shaft assembly 200 further comprises an auxiliary shaft 250, and the first shell 220 is further provided with a containing cavity 223 communicating with the mounting cavity 222, the mounting cavity 222 and the containing cavity 223 are arranged along the first direction, and the auxiliary shaft 250 partially protrudes out of the shaft hole 221, the second shell 230 cooperates with the first shell 220 to limit the auxiliary shaft 250 from disengaging, and the plug housing 110 is rotationally connected with the rotating shaft 243 and the auxiliary shaft 250 of the rotating shaft module 240, respectively.

[0060] The first shell 220 is arched, and the second shell 230 is embedded in the first shell 220, the second shell 230 comprises a base plate and a protrusion arranged on the surface of the base plate perpendicular to the surface of the base plate, during installation, the rotating shaft module 240 is installed in the mounting cavity 222 through the containing cavity 223, the shaft sleeve 241 of the rotating shaft module 240 has a flat surface, and when the rotating shaft module 240 is inserted into the mounting cavity 222, the flat surface of the shaft sleeve 241 cooperates with the cavity wall surface of the mounting cavity 222 to limit the position of the rotating shaft module 240, and the rotating shaft of the rotating shaft module 240 protrudes out of the shaft hole 221; after the auxiliary shaft 250 is installed on the other shaft hole 221, the protrusion of the second shell 230 is inserted into the containing cavity 223, the outer wall of the second shell 230 and the inner wall of the first shell 220 are provided with buckles and slots, respectively, and after the clamping is in place, the second shell 230 can be fixed, which is simple and convenient. The auxiliary shaft 250 can further enhance the stability of the plug assembly 100 during rotation. Through the rotational connection of the auxiliary shaft 250 and the plug housing 110, part of the load on the rotating shaft 243 can be shared, and wear or failure caused by excessive stress on a single rotation point can be reduced. In addition, through reasonable component design and assembly sequence, the scheme simplifies the assembly process of the plug assembly 100, reduces the assembly difficulty and cost, and improves the production efficiency.

[0061] Of course, in other embodiments, the first housing 220 and the second housing 230 may be connected by screws, the second housing 230 may be sleeved within the first housing 220, or they may be fixed by adhesive, etc. Two hinge modules 240 may be provided, or the hinge module 240 may have two rotating shafts 243, etc. The shapes of the first housing 220 and the second housing 230 may also be other forms.

[0062] Combine Figure 1 and Figure 5 , regarding the assembly of the plug housing 110 and the mounting base.

[0063] The plug housing 110 is connected to the rotating shaft of the rotating shaft assembly 200. In one embodiment, for the convenience of installation, the plug housing 110 includes a shell body 111 and a connecting shell 112 of the connecting shell body 112. Both ends of the connecting shell 112 are provided with connecting parts 113, and the connecting part 113 is also provided with a connecting hole. The connecting part 113 is connected to the rotating shaft 243 of the rotating shaft assembly 200 through the connecting hole. The shell body 111 provides a sturdy shell that can resist interference and damage from the external environment and ensure the normal operation of the plug assembly 100. The design of the connecting shell 112 enables the plug housing 110 to flexibly cooperate with the rotating shaft assembly 200 to realize the rotation of the plug. At the same time, the connecting shell 112 also plays a role in strengthening and supporting the shell body 111, thereby improving the overall strength and stability of the plug assembly 100.

[0064] The shape of the connection portion 113 is typically determined by the specific design and intended use of the plug assembly 100. Common shapes for the connection portion 113 include circular, square, and oval. It should be noted that the shape of the connection portion 113 may be limited by the overall shape and size of the plug housing 110 and may also be irregular. Therefore, the shape of the connection portion 113 only needs to ensure a tight fit and stable connection between the connection portion 113 and the rotating shaft 243 of the shaft assembly 200.

[0065] Specifically, to facilitate assembly, the housing body 111 is sleeved over the connecting housing 112 and secured thereto by a snap-fit ​​connection. This ensures a tight fit between the housing body 111 and the connecting housing 112. This snap-fit ​​connection between the housing body 111 and the connecting housing 112 is simpler and faster than other connection methods (such as bolting or welding). This helps reduce assembly difficulty and cost, and improves production efficiency.

[0066] Furthermore, a first plug-in portion 114 is provided in the shell body 111 , and a second plug-in portion 115 is correspondingly provided in the connecting shell 112 . The shell body 111 and the connecting shell 112 are matched with each other through the first plug-in portion 114 and the second plug-in portion 115 .

[0067] In the process of assembling the shell body 111 and the connecting shell 112, the cooperation of the first plug-in part 114 and the second plug-in part 115 can ensure the accurate alignment of the shell body 111 and the connecting shell 112 during the assembly process, which helps to avoid misalignment or deviation during the assembly process, thereby improving the overall assembly accuracy of the plug assembly 100. In addition, through the cooperation of the first plug-in part 114 and the second plug-in part 115, the connection between the shell body 111 and the connecting shell 112 is more firm. This helps to enhance the overall structural stability of the plug assembly 100 and improve its impact resistance and shock resistance.

[0068] In an embodiment, the first plug-in part 114 can be designed in the form of a slot, and the second plug-in part 115 is designed in the form of a plug that matches the slot. By inserting the plug into the slot, the predetermined positioning of the shell body 111 and the connecting shell 112 is achieved.

[0069] In an embodiment, the first plug-in part 114 can be designed in the form of a buckle, and the second plug-in part 115 is designed in the form of a buckle slot that matches the buckle. By inserting the buckle into the buckle slot, the predetermined positioning of the shell body 111 and the connecting shell 112 is achieved. This structure generally has strong fixing force and stability.

[0070] Referring Figures 1 to 4 The utility model also proposes a plug base 300, the plug base 300 includes base shell 310 and circuit mainboard, and the circuit mainboard is located in the base shell 310, and is electrically connected with the plug pin 120, and the base shell 310 is clamped with the plug assembly 100. Various electronic components and circuits are integrated on the circuit mainboard, such as rectifier, filter, transformer, voltage stabilizer, etc., and the specific design of the circuit mainboard should consider factors such as electrical performance, heat dissipation performance and electromagnetic compatibility, which are not limited by the scheme. The circuit mainboard can be any circuit mainboard used in existing chargers.

[0071] In order to make the charger more compact, the base shell 310 is provided with a mounting groove 311 and a clearance groove 312 communicating with the mounting groove 311, and the mounting base 210 is partially arranged in the mounting groove 311. The clearance groove 312 is adapted to the profile of the plug housing 110. When the plug pin 120 approaches the base shell 310, part of the plug housing 110 is located in the clearance groove 312, and part of the plug housing 110 is exposed outside the base shell 310. Specifically, the mounting groove 311 is arranged at the edge of the base shell 310 and penetrates through the base shell 310. The mounting groove 311 extends out of the side of the base shell 310 away from the clearance groove 312, so that the shaft module 240 of the shaft assembly 200 approaches the surface of the base shell 310, thereby making the plug assembly more fit the base shell 310 after being turned over.

[0072] In one aspect, when the plug assembly 100 is semi-stored in the base shell 310, part of the plug housing 110 is exposed outside the base shell 310, so that the user can hold and operate the plug more easily when plugging or unplugging the plug. Compared with the fully-stored design, the plug assembly 100 semi-stored in the base shell 310 can save certain material and manufacturing costs, because the fully-stored design requires a larger base shell 310 to accommodate the entire plug assembly 100, while the semi-stored design only needs to accommodate part of the structure of the plug assembly 100, which helps to reduce production costs and improve the competitiveness of the product. More importantly, the semi-stored design allows the plug assembly 100 to occupy only part of the space in the base shell 310, thereby providing more layout space for electrical components such as circuit boards. This helps to arrange the circuit layout more flexibly in limited space, optimizes the arrangement and connection of electrical components, and thus improves the integration and compactness of the entire plug assembly 100.

[0073] The utility model further provides a charger, the charger is after the electrical connection of above-mentioned plug assembly 100 and plug base 300, through installing base 210 and base shell 310 clamping fixed composition.
