[0010] Optionally, the positive and negative plug assembly includes a positive plug, a negative plug, and a positive and negative rotating component; the positive plug and the negative plug are respectively connected to the positive and negative rotating component, and the positive plug and the negative plug are spaced apart; the ground rotating component has a first positive and negative locking slot and a second positive and negative locking slot; the positive and negative locking component has a second locking block, when the positive and negative plug assembly is in the retracted position, the second locking block is located in the first positive and negative locking slot; when the ground plug assembly is in the unfolded position, the second locking block is located in the second positive and negative locking slot.

The locking assembly is movably connected to the housing and is used to lock the ground plug assembly in the retracted or extended position. With this structure, the ground plug assembly can rotate independently and be retracted separately. On the one hand, when only the positive and negative plug assemblies need to be plugged in, the ground plug assembly can be rotated to the retracted position without interfering with the plugging of the positive and negative plug assemblies. On the other hand, when the positive and negative plug assemblies and the ground plug assembly need to be used together, the ground plug assembly can be rotated to the extended position to form a three-pole plug structure. Therefore, the ground plug assembly can be retracted and extended independently, better adapting to diverse global socket standards. In addition, the locking component can lock the ground pin assembly in the retracted position or the extended position, thus preventing the ground pin assembly from accidentally extending in the retracted position and allowing the ground pin assembly to rotate in the extended position and when used for insertion, thereby effectively reducing safety risks during use.

Detailed Implementation

[0038] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0039] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0040] Reference Figures 1 to 3 This application provides a plug device 100, which includes: a housing 1, positive and negative plug components 2, a ground plug component 3, and a locking component 4. The positive and negative plug components 2 are connected to the housing 1; the ground plug component 3 is rotatably connected to the housing 1 and can be rotated to a retracted position or an unfolded position. The ground plug component 3 and the positive and negative plug components 2 are located on the same side of the housing 1; the locking component 4 is movably connected to the housing 1 and is used to lock the ground plug component 3 in the retracted position or the unfolded position.

[0041] Based on the above structure, the ground electrode pin assembly 3 can rotate independently and be stored separately. On the one hand, referring to... Figure 2 When only the positive and negative pin assembly 2 needs to be connected, the ground pin assembly 3 can be rotated to the storage position without interfering with the connection of the positive and negative pin assembly 2. On the other hand, referring to... Figure 3When the positive and negative plug components 2 and the ground plug component 3 need to be used together, the ground plug component 3 is rotated to the unfolded position to form a three-prong plug structure. Thus, the ground plug component 3 can be stored and unfolded independently, better adapting to the diverse global socket 200 standard. Furthermore, the locking component 4 can lock the ground plug component 3 in either the stored or unfolded position. This prevents accidental unfolding of the ground plug component 3 in the stored position and also prevents rotation of the ground plug component 3 in the unfolded position and during plugging, effectively reducing safety risks during use.

[0042] Specifically, when the local polar plug component 3 is in the storage position, refer to Figure 1 and Figure 2 Then, the ground electrode pin assembly 3 rotates into the housing 1 and does not protrude from the surface of the housing 1. When the ground electrode pin assembly 3 is in the unfolded position, refer to... Figure 3 Then the ground pin assembly 3 rotates to protrude from the housing 1 and can cooperate with the positive and negative pin assemblies 2 to be plugged into an external socket.

[0043] Reference Figures 3 to 13 In some embodiments, the locking assembly 4 includes: a pressing member 41, movably inserted into the housing 1; a ground electrode locking member 42, disposed within the housing 1, connected to the pressing member 41, and used to lock the ground electrode pin assembly 3 in a retracted or unfolded position; and a first reset member 43, disposed within the housing 1, with one end connected to the housing 1 and the other end connected to the side of the ground electrode locking member 42 opposite to the pressing member 41, used to reset the pressing member 41 and the ground electrode locking member 42. The pressing member 41 may be partially located outside the housing 1, and is used by the user to press it to switch the ground electrode pin assembly 3 from the retracted position to the unfolded position. Therefore, using the pin assembly provided in this application, the user only needs to press the pressing member 41 to switch the ground electrode pin assembly 3 from the retracted position to the unfolded position.

[0044] Reference Figures 4 to 8 Specifically, when the ground electrode pin assembly 3 is in the retracted position, the ground electrode locking member 42 locks the ground electrode pin assembly 3 in the retracted position to prevent it from accidentally unfolding. When the ground electrode pin assembly 3 needs to be used, the user presses the pressing member 41. At this time, the pressing member 41 moves inward toward the housing 1, driving the ground electrode locking member 42 to move, and simultaneously compressing the first reset member 43. At this time, the ground electrode locking member 42 releases its lock on the ground electrode pin assembly 3, and the ground electrode pin assembly 3 can rotate from the retracted position to the unfolded position under the action of external force. When the user releases the pressing member 41, the first reset member 43 can push the ground electrode locking member 42 and the pressing member 41 to reset under the action of elastic reset force, referring to... Figure 9 and Figure 12 At this time, the ground electrode locking member 42 relocks the ground electrode pin assembly 3 to lock the ground electrode pin assembly 3 in the unfolded position to prevent the ground electrode pin assembly 3 from rotating when it is plugged in. The first reset member 43 can be a spring, one end of which abuts against the inner wall of the housing 1, and the other end of which abuts against the side of the ground electrode locking member 42 away from the pressing member 41.

[0045] Reference Figure 9 , Figure 12 , Figure 14 and Figure 15 In some embodiments, the ground electrode pin assembly 3 includes a ground electrode pin 31 and a ground electrode rotating member 32 connected to each other; the ground electrode rotating member 32 has a first ground electrode slot 321 and a second ground electrode slot 322; the ground electrode locking member 42 has a first locking block 421. When the ground electrode pin assembly 3 is in the retracted position, the first locking block 421 is located in the first ground electrode slot 321; when the ground electrode pin assembly 3 is in the unfolded position, the first locking block 421 is located in the second ground electrode slot 322. It can be understood that when the ground electrode pin assembly 3 rotates, the positions of the first ground electrode slot 321 and the second ground electrode slot 322 rotate relative to the first locking block 421. When the ground electrode pin assembly 3 rotates to the retracted position, the position of the first ground electrode slot 321 corresponds to the first locking block 421, and the first reset member 43 can push the ground electrode locking member 42 to reset under the action of the elastic reset force, so that the first locking block 421 is placed into the first ground electrode slot 321. Similarly, when the ground electrode pin assembly 3 is rotated to the unfolded position, the position of the second ground electrode slot 322 corresponds to the first locking block 421. Under the action of the elastic reset force, the first reset member 43 can push the ground electrode locking member 42 to reset, so that the first locking block 421 is placed into the second ground electrode slot 322. Thus, the ground electrode pin assembly 3 only needs to be rotated into position, and with the cooperation of the first reset member 43 and the ground electrode locking member 42, the ground electrode pin assembly 3 can be quickly locked without the need for additional locking operations by the user, greatly improving the convenience of use.

[0046] Reference Figure 4 and Figure 5 , Figures 8 to 10 ,as well as Figure 15In some embodiments, the ground electrode rotating member 32 is provided with a first protrusion 323; the pin device 100 also includes a ground electrode resetting member 5, which is disposed inside the housing 1, and both ends of the ground electrode resetting member 5 abut against the inner wall of the housing 1 and the first protrusion 323, respectively. The ground electrode resetting member 5 is used to provide rotational force for the ground electrode rotating member 32. Specifically, the ground electrode resetting member 5 can be a torsion spring, and both ends of the torsion spring abut against the inner wall of the housing 1 and the first protrusion 323, respectively. Thus, when the user presses the pressing member 41, the elastic resetting force of the ground electrode resetting member 5 can cause the ground electrode rotating member 32 to rotate, and drive the ground electrode pin 31 to quickly rotate from the retracted position to the unfolded position. When the ground electrode pin 31 is not needed, the user pushes the ground electrode pin 31 by hand, and the ground electrode pin 31 and the ground electrode rotating member 32 rotate synchronously. When the ground pole pin assembly 3 is in the storage position, the first locking block 421 is inserted into the second ground pole locking slot 322, and the ground pole pin assembly 3 is locked in the storage position.

[0047] In some embodiments, the positive and negative plug assembly 2 is rotatably connected to the housing 1; the positive and negative plug assembly 2 can rotate to a retracted position or an unfolded position, and the locking assembly 4 is used to lock the positive and negative plug assembly 2 in the retracted position or the unfolded position. Thus, the positive and negative plug assembly 2 can also be folded into the housing 1. (Refer to...) Figure 1 When both the positive and negative plug components 2 and the ground plug component 3 are in the storage position, the size of the plug device 100 can be reduced, making it convenient for users to store and carry.

[0048] Reference Figures 4 to 13 In some embodiments, the locking assembly 4 further includes: a positive and negative electrode locking member 44, disposed within the housing 1, connected to the pressing member 41, and used to lock the positive and negative electrode plug assembly 2 in the retracted or unfolded position; and a second reset member 45, disposed within the housing 1, with one end connected to the housing 1 and the other end connected to the side of the positive and negative electrode locking member 44 opposite to the pressing member 41, used to reset the pressing member 41 and the positive and negative electrode locking member 44. Thus, the user only needs to press the pressing member 41 to simultaneously release the locking of the positive and negative electrode plug assembly 2 and the ground electrode plug assembly 3, enabling them to simultaneously switch from the retracted position to the unfolded position, greatly improving operational convenience. Understandably, if only the positive and negative pin assembly 2 is needed, the user can simply push the ground pin assembly 3 back to its storage position. The method for locking and unlocking the positive and negative pin assembly 2 is the same as the operating principle of the ground pin assembly 3, and will not be described further here. Furthermore, since the positive and negative locking actuator 44 and the ground locking actuator 42 are independently configured, pushing the ground pin assembly 3 back to its storage position does not affect the locking of the positive and negative pin assembly 2 by the positive and negative locking actuator 44.

[0049] Reference Figure 16 and Figure 17 In some embodiments, the positive and negative terminal assembly 2 includes a positive terminal 21, a negative terminal 22, and a positive and negative terminal rotating member 23; the positive terminal 21 and the negative terminal 22 are respectively connected to the positive and negative terminal rotating member 23, and the positive terminal 21 and the negative terminal 22 are spaced apart; the ground terminal rotating member 32 has a first positive and negative terminal slot 231 and a second positive and negative terminal slot 232; see reference Figure 8 and Figure 13 The positive and negative electrode locking mechanism 44 is equipped with a second locking block 441. When the positive and negative electrode plug assembly 2 is in the retracted position, the second locking block 441 is located in the first positive and negative electrode slot 231; when the ground electrode plug assembly 3 is in the unfolded position, the second locking block 441 is located in the second positive and negative electrode slot 232. Both the ground electrode rotating component 32 and the positive and negative electrode rotating component 23 can be made of insulated plastic. Specifically, the locking and unlocking operation of the positive and negative electrode rotating component 23 is consistent with the operating principle of the ground electrode rotating component 32, and will not be described in detail here. Therefore, the positive and negative electrode plug assembly 2 only needs to be rotated into position, and with the cooperation of the second reset component 45 and the positive and negative electrode locking mechanism 44, the positive and negative electrode plug assembly 2 can be quickly locked without requiring additional locking operations from the user, greatly improving ease of use.

[0050] Reference Figures 4 to 6 and reference Figure 9 , Figure 12 and 16 In some embodiments, the positive and negative electrode rotating member 23 is provided with a second protrusion 233; the plug device 100 also includes a positive and negative electrode resetting member 6, which is disposed inside the housing 1, and both ends of the positive and negative electrode resetting member 6 abut against the inner wall of the housing 1 and the second protrusion 233, respectively. The positive and negative electrode resetting member 6 is used to provide rotational force for the positive and negative electrode rotating member 23. Specifically, the positive and negative electrode resetting member 6 can be a torsion spring, and both ends of the torsion spring abut against the inner wall of the housing 1 and the second protrusion 233, respectively. Thus, when the user presses the pressing member 41, the elastic resetting force of the positive and negative electrode resetting member 6 can cause the positive and negative electrode rotating member 23 to rotate, and drive the positive and negative electrode plugs 22 to quickly rotate from the storage position to the unfolded position. When the positive and negative electrode plugs 22 are not needed, the user can push the positive and negative electrode plugs 22 by hand, and the positive and negative electrode plugs 22 and the positive and negative electrode rotating member 23 will rotate synchronously. When the positive and negative plug assembly 2 is in the storage position, the first locking block 421 is inserted into the second positive and negative plug slot 232, and the positive and negative plug assembly 2 is locked in the storage position.

[0051] Reference Figure 4In some embodiments, the ground electrode plug assembly 3 includes a ground electrode plug 31 and a ground electrode rotating member 32 connected to each other; when both the positive and negative electrode plug assemblies 2 and the ground electrode plug assembly 3 are in the retracted position, the ground electrode plug 31 is located between the positive electrode plug 21 and the negative electrode plug 22. Thus, the ground electrode plug 31, the positive electrode plug 21, and the negative electrode plug 22 can be rationally arranged, which not only improves space utilization but also makes the plug device 100 more compact when stored, making it easier to store and carry.

[0052] Reference Figure 3 In some embodiments, the housing 1 has a receiving groove 11. When both the positive and negative plug components 2 and the ground plug component 3 are in the retracted position, the positive and negative plug components 2 are at least partially located within the receiving groove 11, and the ground plug component 3 is at least partially located within the receiving groove 11. Therefore, in the retracted position, the positive and negative plug components 2 and the ground plug component 3 can be located within the receiving groove 11, avoiding protrusion from the surface of the housing 1, further making the plug device 100 more compact when retracted, and easier to store and carry. The receiving groove 11 may be recessed and partially communicate with the interior of the housing 1 to allow the positive and negative plug components 2 and the ground plug component 3 to connect with the copper contact plate inside the housing 1.

[0053] Reference Figures 18 to 20 This application also provides a socket 200, which includes the above-described plug device 100.

[0054] In the plug device 100 and socket 200 provided in this application, the ground pin assembly 3 can rotate independently and be stored separately. On the one hand, when only the positive and negative pin assemblies 2 need to be plugged in, the ground pin assembly 3 can be rotated to the stored position without interfering with the plugging of the positive and negative pin assemblies 2. On the other hand, when the positive and negative pin assemblies 2 and the ground pin assembly 3 need to be used together, the ground pin assembly 3 can be rotated to the unfolded position to form a three-prong plug structure. Thus, the ground pin assembly 3 can be stored and unfolded independently, which can better adapt to the diverse socket 200 standards worldwide. In addition, the locking assembly 4 can lock the ground pin assembly 3 in the stored position or the unfolded position. This can prevent the ground pin assembly 3 from being accidentally unfolded when in the stored position, and can also prevent the ground pin assembly 3 from rotating when in the unfolded position and when used for plugging, thereby effectively reducing the safety risks during use.
