[0054] To enable those skilled in the art to better understand the technical solutions of this application, the charger provided in this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It is understood that the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0055] The terms "first," "second," etc., used in this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0056] As a crucial connector for electrical connection between electronic devices and sockets, chargers need to be compatible with various scenarios and different types of sockets. However, most existing chargers only support unidirectional insertion and removal, failing to accommodate other directions. This leads to difficulties in use or inability to plug into sockets where other chargers or cables are already connected. To address these issues, the charger of this application utilizes a first and second assembly structure to achieve detachable assembly of the main body and the plug module. Furthermore, it allows adjustment of the assembly state between the plug module and the main body, enabling the plug module to achieve at least a 90-degree directional change, thereby adapting to sockets in different application scenarios.

[0057] This application provides a charger, which includes a first plug, a second plug, and a locking device. The first plug is rotatable, meaning it is retractable, and the first plug, in conjunction with the locking device, can achieve a stable state, ensuring the stability of the plug during charging. Simultaneously, the first and second plugs are electrically connected, and the locking device can be configured to detach and assemble the first and second plugs, thereby achieving relative fixation of the first and second plugs. Different second plugs can meet the power socket specifications of different countries or regions.

[0058] Specifically, please refer to Figures 1-11. In the first embodiment, the first and second pins of the charger 1 in this embodiment are in a disassembled state. As shown in Figures 1-11, the charger 1 in this embodiment includes a first pin 10, a locking device 40, a first limiting structure 50, a fixing plate 60, a faceplate 70, and a housing 80.

[0059] As shown in Figures 7 and 8, the faceplate 70 is provided with a first accommodating space 701, and the housing 80 is provided with a second accommodating space 81. The faceplate 70 covers the housing 80, and the first accommodating space 701 communicates with the second accommodating space 81, thus achieving a mating arrangement between the faceplate 70 and the housing 80. Furthermore, a portion of the first pin 10, the locking device 40, and the first limiting structure 50 are disposed within the first accommodating space 701 and housed between the faceplate 70 and the housing 80, thereby achieving fixation and safety protection for the first pin 10, the locking device 40, and the first limiting structure 50.

[0060] Specifically, as shown in Figures 7 and 8, the face shell 70 is provided with a first accommodating space 701 and a fourth limiting structure 704. The fourth limiting structure 704 and the first accommodating space 701 are arranged adjacent to each other and located on both sides of the face shell 70. The side walls of the fourth limiting structure 704 and the first accommodating space 701 share the same side wall, and the extension direction Y of the fourth limiting structure 704 is parallel to and opposite to the extension direction Z of the first accommodating space 701.

[0061] Furthermore, the fourth limiting structure 704 and the first accommodating space 701 share the same sidewall, and a first opening 702 is formed on the shared sidewall. The first accommodating space 701 and the fourth limiting structure 704 are connected to each other through the first opening 702.

[0062] As shown in Figures 1 and 8, the first limiting structure 50 is disposed in the first accommodating space 701 and is exposed to the fourth limiting structure 704 through the first opening 702. Specifically, the first limiting structure 50 in this embodiment includes a rotating shaft 51, as shown in Figure 5, the rotating shaft 51 is provided with mounting grooves 53 and limiting grooves 52 at intervals along the axial direction of the rotating shaft 51.

[0063] Optionally, the fourth limiting structure 704, the first opening 702, and the first accommodating space 701 are arranged sequentially along the first direction X, wherein the first direction X is perpendicular to the axial direction of the rotating shaft 51.

[0064] Specifically, in this embodiment, the limiting groove 52 is located at the center of the rotating shaft 51, and there are multiple limiting grooves 52, which are spaced apart along the circumference of the rotating shaft 51. As shown in FIG10, the limiting groove 52 includes at least a first limiting groove 521 and a second limiting groove 522. The first limiting groove 521 is disposed through the rotating shaft 51, and the second limiting groove 522 is connected to the first limiting groove 521.

[0065] The mounting slot 53 is used to mount the first pin 10, so that the first end of the first pin 10 is fixed to the rotating shaft 51. In this embodiment, there are two mounting slots 53, respectively located at both ends of the rotating shaft 51. Specifically, in this embodiment, the mounting slots 53 and the first ends of the first pin 10 are fixed to each other by an interference fit.

[0066] As shown in Figure 1, a portion of the first pin 10 is disposed within the first accommodating space 701. Specifically, the first end of the first pin 10 inserted into the mounting groove 53 is disposed within the first accommodating space 701, and the second end of the first pin 10 protrudes from the face shell 70 through the first opening 702. Specifically, as shown in Figures 9 and 10, the mounting groove 53 is configured to cooperate with the first end of the first pin 10, fixing the first end of the first pin 10 and the rotating shaft 51. The rotating shaft 51 is used to drive the first pin 10 to rotate, thereby controlling the first pin 10 to switch between a first position and a second position. Specifically, it can control the second end of the first pin 10 to be housed within the fourth limiting structure 704 or disposed perpendicular to the face shell 70.

[0067] Optionally, as shown in Figure 1, when the second end of the first pin 10 is perpendicular to the faceplate 70, the charger 1 can be inserted into the external charging socket. At this time, the bottom wall of the first accommodating space 701 abuts against the external charging socket, and the first pin 10 is electrically connected to the charging circuit of the external charging socket. Optionally, as shown in Figure 11, when the second end of the first pin 10 is retracted into the fourth limiting structure 704, the charger 1 is in a retracted state, making it convenient for users to store and carry.

[0068] As shown in Figures 9 and 10, the locking device 40 of this embodiment is detachably configured to cooperate with the first limiting structure 50. The locking device 40 is movably inserted through the first limiting structure 50 to realize the switching between the locked state and the unlocked state of the first plug 10 in the first position or the second position, so as to ensure that the charger 1 can maintain the same state when using or storing the first plug 10.

[0069] Further, as shown in FIG2, the locking device 40 of this embodiment includes an elastic structure 42. As shown in FIG9, the elastic structure 42 includes a rotating part 421 and a fixing part 422. The two rotating parts 421 are rotatably disposed at both ends of the rotating shaft 51, that is, the rotating parts 421 are sleeved on both ends of the rotating shaft 51, and the fixing part 422 connects the two rotating parts 421. Optionally, the diameters of the two ends of the rotating shaft 51 are smaller than the diameter of the middle part of the rotating shaft 51, and the diameter of the rotating part 421 is equal to the diameter of the middle part of the rotating shaft 51. As shown in FIG8, a third limiting structure 72 is provided on the side of the faceplate 70 facing the fixing plate 60, and the fixing part 422 is fixedly disposed within the third limiting structure 72.

[0070] Specifically, in this embodiment, the elastic structure 42 is a torsion spring, and the two rotating parts 421 and the fixed part 422 are springs with an integrally formed structure. When the rotating shaft 51 drives the rotating part 421 to rotate, the elastic structure 42 generates a certain elastic force. Since the fixed part 422 is fixedly set in the third limiting structure 72, the elastic force is stored in the elastic structure 42.

[0071] Alternatively, in other embodiments, the elastic structure 42 may also be other elastic structures capable of generating and storing elastic force.

[0072] Further, as shown in FIG2, the locking device 40 of this embodiment includes a sliding switch 41. As shown in FIG7, the faceplate 70 is further provided with a second opening 703. As shown in FIG1, the first end of the sliding switch 41 is exposed in the second opening 703. The sliding switch 41 moves along the first direction X, that is, moves along the radial direction of the rotating shaft 51, so as to control the second end of the sliding switch 41 to pass through the first limiting groove 521 or the second limiting groove 522, so as to realize the assembly or disassembly with the first limiting structure 50.

[0073] Specifically, as shown in Figure 3, the slide switch 41 includes a main body 411, a first extension 412, a second extension 413, and a third extension 414. The first extension 412 is disposed on the side of the main body 411 near the second opening 703. The length of the first extension 412 along the first direction X is less than the length of the second opening 703 along the first direction X. The first extension 412 can move within the second opening 703 along the first direction X, allowing the slide switch 41 to slide along the first direction X. Furthermore, the fixing part 422 abuts against the side of the main body 411 opposite to the first extension 412.

[0074] The first end of the second extension 413 is parallel to the main body 411 and extends toward the first limiting structure 50. When the slide switch 41 moves along the first direction X and toward the pivot 51, the first end of the second extension 413 is inserted into the limiting groove 52. The second end of the second extension 413 connects the main body 411 and the first end of the second extension 413. Optionally, in this embodiment, the second extension 413 is L-shaped, and the second end of the second extension 413 is perpendicular to the main body 411 and the first end of the second extension 413.

[0075] Optionally, as shown in FIG10, the first limiting groove 521 and the second limiting groove 522 in this embodiment are arranged perpendicularly to each other, so that when the second extension 413 is inserted into the first limiting groove 521 or the second limiting groove 522, the first pin 10 can achieve an angle change of at least 90°.

[0076] The third extension 414 is disposed on the side of the main body 411 away from the first extension 412 and away from the second extension 413, and the third extension 414 extends in a direction away from the main body 411. The third extension 414 is provided with a through hole 415. Optionally, the through hole 415 is disposed at the center of the third extension 414.

[0077] As shown in Figures 2 and 8, the locking device 40 also includes a positioning rod 43 and an elastic element 44, wherein the elastic element 44 is sleeved on the positioning rod 43, the positioning rod 43 passes through the through hole 415, and is used to fix the position of the sliding switch 41.

[0078] Specifically, as shown in Figure 8, the first end of the positioning rod 43 is fixed to the side wall of the face shell 70, specifically the side wall of the first accommodating space 701 away from the rotating shaft 51. The positioning rod 43 is arranged parallel to the first direction X, that is, the second end of the positioning rod 43 extends towards the direction close to the rotating shaft 51, extending until the projection of the second end of the positioning rod 43 on the face shell 70 is located within the third limiting structure 72. At the same time, the second end of the positioning rod 43 abuts against the side of the fixing part 422 away from the sliding switch 41. The positioning rod 43, in conjunction with the third limiting structure 72, fixes the fixing part 422 of the elastic structure 42 within the third limiting structure 72, thereby fixing the sliding switch 41 that abuts against the fixing part 422.

[0079] The elastic element 44 is sleeved on the positioning rod 43, wherein the first end of the elastic element 44 abuts against the third extension 414, and the second end of the elastic element 44 abuts against the side wall of the face shell 70, for providing elastic force between the sliding switch 41 and the face shell 70. Specifically, when the sliding switch 41 moves towards the end closer to the rotating shaft 51, that is, when the first extension 412 abuts against one side wall of the second opening 703, the elastic element 44 is in a relaxed state and does not generate elastic force; when the sliding switch 41 moves away from the rotating shaft 51, that is, when the first extension 412 abuts against the other side wall of the second opening 703, the elastic element 44 is in a compressed state, and the elastic force generated by the elastic element 44 causes the sliding switch 41 to move towards the rotating shaft 51 until the second extension 413 is inserted into the limiting groove 52, thereby locking the rotating shaft 51.

[0080] The locking device 40 in this embodiment includes a sliding switch 41, an elastic structure 42, an elastic element 44, and a positioning rod 43. The locking device 40 works in conjunction with the rotating shaft 51 to enable the rotating shaft 51 to drive the first plug 10 to rotate, allowing free switching between locked and unlocked states. At the same time, the elastic force generated by the elastic element 44 and the elastic structure 42 can automatically reset the sliding switch 41, ensuring that the state of the rotating shaft 51 and the first plug 10 is fixed under any circumstances. This effectively prevents other potential problems caused by the state switching of the first plug 10, such as the charger 1 falling off due to the rotation of the rotating shaft 51 and the first plug 10 during charging.

[0081] Further, as shown in Figures 2 and 9, the fixing plate 60 is disposed on the side of the locking device 40 opposite to the face shell 70, so as to clamp the first limiting structure 50 between the fixing plate 60 and the face shell 70. Specifically, the fixing plate 60 abuts against the first limiting structure 50, the locking device 40 and the face shell 70, and is used to cooperate with the face shell 70 to fix the first limiting structure 50 and the locking device 40.

[0082] Specifically, as shown in Figure 6, the fixing plate 60 includes a base plate 61 and a first mounting part 62 and a second mounting part 63 disposed on the base plate 61. The first mounting part 62 includes an arc-shaped mounting plate for mounting the rotating shaft 51. The second mounting part 63 is spaced apart from the first mounting part 62, and the second mounting part 63 includes two straight plates extending toward the face shell 70. The center height of the straight plates is lower than the edge height of the straight plates. The fixing part 422 can be disposed at the center position of the straight plate on the side of the straight plate close to the face shell 70.

[0083] A third mounting portion 64 is further provided on the base plate 61, as shown in Figure 8. A fourth mounting portion 73 is further provided on the side of the faceplate 70 facing the first accommodating space 701, as shown in Figure 2. The charger 1 also includes fixing screws 90. Specifically, the fixing screws 90 can be sequentially inserted into the third mounting portion 64 and the fourth mounting portion 73 to fix the faceplate 70 and the fixing plate 60. Optionally, the fixing screws 90 can be provided at the corner of the fixing plate 60, and the number of fixing screws 90 is not limited.

[0084] This application also provides another charger 1, which is compatible with charging sockets of another national standard. Specifically, please refer to Figures 12-15. In the second embodiment, the charger 1 of this embodiment further includes a second plug 20, and the first plug 10 and the second plug 20 are in an assembled state. A locking device 40 is movably disposed within the second limiting structure formed by the first limiting structure 50 and the second plug 20, for fixing the second plug 20 and the first plug 10.

[0085] As shown in Figure 12, the charger 1 in this embodiment includes a second plug 20, which is sleeved on the first plug 10 so that the second plug 20 and the first plug 10 are relatively fixedly arranged. A second limiting structure is formed at the first end of the second plug 20, and the first plug 10 is electrically connected to the second plug 20 through the second limiting structure.

[0086] Specifically, the first end of the second pin 20 is formed with a second limiting structure. Part of the second limiting structure is used to engage the first pin 10, and another part of the second limiting structure is inserted into the first limiting structure 50. The locking device 40 is sequentially inserted into the first limiting structure 50 and the second limiting structure to fix the second pin 20 and the first pin 10.

[0087] As shown in Figure 7, the faceplate 70 is further provided with a fifth limiting structure 705, wherein the fifth limiting structure 705 and the fourth limiting structure 704 are arranged sequentially along the first direction X. The rotating shaft 51 drives the first pin 10 to rotate, which in turn drives the second pin 20 to rotate, so that the second end of the second pin 20 away from the faceplate 70 is housed in the fifth limiting structure 705 and the fourth limiting structure 704 or is arranged perpendicular to the faceplate 70.

[0088] As shown in Figures 13 and 14, the second pin 20 includes a first pin body 21, a first pin 22, a first cover plate 23, and a first conductive structure 24. The first pin 22 is disposed on the first pin body 21, the first conductive structure 24 is disposed inside the first pin body 21, and the first cover plate 23 covers the side of the first pin body 21 opposite to the first pin 22.

[0089] Specifically, the first pin body 21 is provided with a first channel 211, which extends through the first pin body 21. The first end of the first pin 22 is inserted into the first end of the first channel 211, and the second end of the first pin 22 extends away from the first channel 211 and protrudes from the first pin body 21. A first mounting structure 231 is provided on one side of the first cover plate 23, which is inserted into the second end of the first channel 211 to fix the first pin body 21 and the first cover plate 23. The internal space 232 of the first mounting structure 231 communicates with the first channel 211. Optionally, the first mounting structure 231 and the first channel 211 can be fixed to each other through an interference fit.
