DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] The present application provides a plug to solve the problem in the related art that the length of the plug pins is generally long, which leads to a larger overall volume of the plug and makes the plug inconvenient to carry and store.

[0031] As shown in Figures 1 and 2, the plug includes a shell 10 and a pin assembly 20. The plug can be set on charging products such as chargers, mobile power supplies, and sockets. It should be noted that the shell 10 is configured to provide support and protection for devices such as the pin assembly 20. The overall shape of the shell 10 can be a rectangular parallelepiped, a cube, a cylinder, or other shapes, and this application does not impose specific restrictions. The pin assembly 20 includes two spaced pins 21. The pins 21 are made of metal material and are configured to be inserted into the socket to achieve electrical connection between the plug and the device to be charged through the pins 21, thereby achieving electrical connection between the power supply and the device to be charged. The device to be charged can be a mobile phone, tablet computer, gaming device, AR (Augmented Reality) device, data storage device, audio playback device, video playback device, desktop computing device, or wearable device. The wearable device can be an electronic watch, electronic glasses, electronic helmet, electronic bracelet, electronic necklace, and other devices.

[0032] Specifically, the pin assembly 20 also includes a mounting bracket 22, which is connected to the housing 10. The pin 21 is rotatably connected to the mounting bracket 22 via a first rotating shaft 24 (see FIG10 ), allowing it to switch between an extended position (see FIG1 ) and a retracted position (see FIG2 ). The axial direction of the first rotating shaft 24 is perpendicular to the insertion direction of the pin 21. It should be noted that the pin 21 is rotatable relative to the mounting bracket 22, and the insertion direction of the pin 21 refers to the direction in which the pin is inserted into the socket.

[0033] When the pin 21 is in the extended position, the length of the pin 21 extends parallel to the insertion direction of the pin 21; when the pin 21 is in the retracted position, the length of the pin 21 extends intersecting the insertion direction of the pin 21. It is understood that the length of the pin 21 can be perpendicular to the insertion direction of the pin 21, and the length of the pin 21 can form other angles with the insertion direction of the pin 21, such as 30 degrees, 45 degrees, 60 degrees, or 75 degrees. As shown in Figure 1, when the pin 21 is needed, the pin 21 is rotated to the extended position. In this position, the portion of the pin 21 protruding from the housing 10 is longer, making it easier to insert the pin 21 into the socket along the insertion direction. As shown in Figure 2, when the pin 21 is no longer needed, the pin 21 is rotated to the retracted position. In this position, the portion of the pin 21 protruding from the housing 10 is shorter, which can reduce the overall size of the plug, making it easier to carry and store.

[0034] Specifically, as shown in Figures 1 to 3, the plug also includes a first transmission mechanism 70, which is disposed on the mounting bracket 22. The two pins 21 are connected by the first transmission mechanism 70. When one pin 21 rotates, the other pin 21 is driven to rotate by the first transmission mechanism 70. When one pin 21 rotates to the extended position, the other pin 21 is driven to the extended position, and when one pin 21 rotates to the retracted position, the other pin 21 is driven to the retracted position. It can be understood that the two pins 21 can be linked by the first transmission mechanism 70, so that rotating either pin 21 can also drive the other pin 21 to rotate, eliminating the need for the user to adjust the positions of the two pins 21 separately, making the use of the pins 21 more convenient.

[0035] Continuing with reference to Figures 1 to 3, in some embodiments of the present application, a receiving slot 60 is provided on the housing 10 and / or the mounting bracket 22. The receiving slot 60 is configured to receive the pin 21 when the rotating bracket 30 is in the storage position. When the pin 21 is in the extended position, the pin 21 extends in a direction away from the bottom wall of the receiving slot 60, and the head end of the pin 21 is located outside the receiving slot 60. When the pin 21 is needed, the pin 21 is rotated to the extended position, at which point the head end of the pin 21 is located outside the receiving slot 60, and the pin 21 can be inserted into the power strip. When the plug is no longer needed, the pin 21 can be rotated into the receiving slot 60 for storage, which can further reduce the overall size of the plug, making it easier to carry and store.

[0036] It should also be noted that the receiving slots 60 may be provided only on the housing 10 or the mounting bracket 22, or may be provided on both the housing 10 and the mounting bracket 22. It should also be noted that the number of receiving slots 60 is the same as the number of pins 21, and there is a one-to-one correspondence between each receiving slot 60 and each pin 21. When there are two pins 21, two receiving slots 60 are also provided, and the two receiving slots 60 are configured to accommodate different pins 21.

[0037] Specifically, as shown in FIG. 3 , the first transmission mechanism 70 includes a first driving gear 71 , a second driving gear 72 , a first transmission gear 73 and a second transmission gear 74 .

[0038] Among them, the first driving gear 71 is connected to the first rotating shaft 24 of one pin 21, and the axial direction of the first driving gear 71 is parallel to the axial direction of the first rotating shaft 24; the second driving gear 72 is connected to the first rotating shaft 24 of the other pin 21, and the axial direction of the second driving gear 72 is parallel to the axial direction of the first rotating shaft 24; the first transmission gear 73 is connected to the mounting bracket 22 for rotation around the axial direction of the first transmission gear 73, the axial direction of the first transmission gear 73 is parallel to the axial direction of the first rotating shaft 24, and the first transmission gear 73 is meshed with the first driving gear 71; the second transmission gear 74 is connected to the mounting bracket 22 for rotation around the axial direction of the second transmission gear 74, the axial direction of the second transmission gear 74 is parallel to the axial direction of the first rotating shaft 24, and the second transmission gear 74 is meshed with the first transmission gear 73 and the second driving gear 72.

[0039] It should be noted that when the pin 21 corresponding to the first driving gear 71 is rotated, the first driving gear 71 drives the first transmission gear 73 to rotate, which in turn drives the second transmission gear 74 to rotate, which in turn drives the second driving gear 72 to rotate, thereby rotating the pin 21 corresponding to the second driving gear 72. Furthermore, it should be understood that the two driving gears are connected via two transmission gears, such that the two pins 21 rotate in opposite directions. For example, when one pin 21 rotates clockwise, it drives the other pin 21 counterclockwise. This allows the two pins 21 to rotate away from each other when rotating from the deployed position to the stowed position, preventing them from interfering with each other's rotation when the distance between them is small. Optionally, the first driving gear 71 has the same number of teeth as the second driving gear 72, and the first transmission gear 73 has the same number of teeth as the second transmission gear 74, so that the first and second pins 21 can rotate synchronously.

[0040] It should also be noted that, according to actual needs, the first transmission mechanism 70 can also be other transmission mechanisms, such as mechanical transmission mechanisms such as connecting rod transmission mechanisms, belt transmission mechanisms or chain transmission mechanisms; the first transmission mechanism 70 can also be an electrical transmission mechanism including electrical equipment such as motors, motors or cylinders.

[0041] As shown in Figures 4 and 5, in some embodiments of the present application, the pin assembly 20 further includes a distance-increasing safety member 25. The distance-increasing safety member 25 is disposed on both sides of the pin 21 along the axial direction of the first rotating axis 24. The distance-increasing safety member 25 is disposed at the edge of the mounting bracket 22. The distance-increasing safety member 25 is configured to increase the axial length of the pin 21 along the first rotating axis 24. It should be noted that the distance-increasing safety member 25 is made of an insulating material. When the pin 21 is in the extended position, the distance-increasing safety member 25 can increase the axial length of the pin 21 along the first rotating axis 24. When a user grasps the plug, the distance-increasing safety member 25 can increase the distance between the user's fingers and the pin 21, preventing electric shock caused by contact between the fingers and the pin 21.

[0042] In one embodiment of the present application, the range-increasing safety member 25 is rotatably connected to the mounting bracket 22 via a second rotating shaft 26 (as shown in FIG. 5 ) to switch between a range-increasing position (as shown in FIG. 5 ) and a range-reducing position (as shown in FIG. 4 ), and the axial direction of the second rotating shaft 26 is perpendicular to the axial direction of the first rotating shaft 24 .

[0043] When the extending safety member 25 is in the extending position, the axial length of the pin 21 along the first rotating shaft 24 is L1. When the extending safety member 25 is in the retracting position, the axial length of the pin 21 along the first rotating shaft 24 is L2. L1 is greater than L2.

[0044] It can be understood that when the plug needs to be used, the safety plate can be rotated to the extended position. At this time, the extended safety member 25 can increase the axial length of the pin 21 along the first rotating shaft 24 to prevent the finger from touching the pin 21 and causing electric shock; when the plug is not needed, the safety plate can be rotated to the shortened position. At this time, the axial length of the pin 21 along the first rotating shaft 24 is smaller, which can reduce the overall volume of the plug, making the plug easy to carry and store.

[0045] As shown in Figures 6 and 7, in one embodiment of the present application, the pin assembly 20 further includes a second transmission mechanism 80, which is disposed on the mounting bracket 22. The first rotating shaft 24 is transmission-connected to the first rotating shaft 24 through the second transmission mechanism 80. When the first rotating shaft 24 rotates, the second rotating shaft 26 is driven to rotate through the second transmission mechanism 80, so that when the pin 21 rotates to the extended position, the distance-increasing safety member 25 is driven to rotate to the distance-increasing position, and when the pin 21 rotates to the stored position, the distance-increasing safety member 25 is driven to rotate to the distance-reducing position.

[0046] It is understood that the plug 21 and the range-extending safety member 25 can be linked via a second transmission mechanism 80, so that when the plug 21 is rotated, the range-extending safety member 25 can be driven to rotate. When the plug is needed, the plug 21 needs to be rotated to the extended position, at which point the range-extending safety member 25 is also driven to the extended position. When the plug is not needed, the plug 21 needs to be rotated to the retracted position, at which point the range-extending safety member 25 is also driven to the retracted position, making the use of the range-extending safety member 25 more convenient. It should also be noted that the second transmission mechanism 80 can be provided between only one plug 21 and the range-extending safety member 25, or between both plugs 21 and the range-extending safety member 25, so that the range-extending safety member 25 can be driven to rotate by rotating either plug 21.

[0047] Referring to Figures 6 to 8, in one embodiment of the present application, the second transmission mechanism 80 includes a third driven gear 81 and a rack 82; the third driven gear 81 is connected to the mounting bracket 22 for rotation around the axial direction of the third driven gear 81, and is transmission-connected to the first rotating shaft 24. The axial direction of the third driven gear 81 is parallel to the axial direction of the first rotating shaft 24, and when the first rotating shaft 24 rotates, it drives the third driven gear 81 to rotate; the rack 82 is connected to the mounting bracket 22 for sliding along the axial direction of the second rotating shaft 26, and the rack 82 is engaged with the third driven gear 81.

[0048] As shown in Figures 7 and 8, a slide rod 83 is connected to the rack 82, and a slide groove 84 is provided on the peripheral side surface 12 of the second rotating shaft 26. The slide groove 84 extends along the axial direction of the second rotating shaft 26 and the circumferential direction of the second rotating shaft 26. The slide rod 83 is inserted into the slide groove 84. When the rack 82 slides along the axial direction of the second rotating shaft 26, the slide rod 83 slides along the slide groove 84 to drive the second rotating shaft 26 to rotate around the axial direction of the second rotating shaft 26.

[0049] It can be understood that the function of the slide groove 84 is the same as that of the slide groove 84 on the cylindrical cam (the specific principle of the cylindrical cam has long been disclosed in the relevant technology and will not be elaborated in this application). When the pin 21 is rotated, the first rotating shaft 24 drives the third driven gear 81 to rotate, and the third driven gear 81 drives the rack 82 to slide along the axial direction of the second rotating shaft 26. At this time, through the cooperation of the slide rod 83 and the slide groove 84, the second rotating shaft 26 is driven to rotate around the axial direction of the second rotating shaft 26, thereby driving the distance increasing safety member 25 to rotate.

[0050] In one embodiment of the present application, as shown in Figure 6, the second transmission mechanism 80 may further include a transition gear 85, which is coaxially arranged and fixedly connected to the first transmission gear 73 or the second transmission gear 74. The transition gear 85 is engaged with the third driven gear 81, and the first rotating shaft 24 is connected to the third driven gear 81 through the transition gear 85. When any one of the pins 21 is rotated, the first transmission gear 73 and the second transmission gear 74 will be driven to rotate, thereby driving the transition gear 85 to rotate, and driving the third driven gear 81 to rotate through the transition gear 85.

[0051] It should also be noted that, according to actual needs, the second transmission mechanism 80 can also be other transmission mechanisms, such as mechanical transmission mechanisms such as connecting rod transmission mechanisms or worm gear transmission mechanisms; the second transmission mechanism 80 can also be an electrical transmission mechanism including electrical equipment such as motors, motors or cylinders.

[0052] As shown in Figures 9 and 10, in some embodiments of the present application, the plug also includes a rotating bracket 30, which is rotatably connected to the shell 10 around a first preset direction AA, and the pin assembly 20 is rotatably connected to the rotating bracket 30 around a second preset direction BB, and the second preset direction BB, the first preset direction AA and the axial direction of the first rotating shaft 24 are perpendicular to each other.

[0053] It should be noted that the rotating bracket 30 is configured to provide support for the pin assembly 20. The rotating bracket 30 can rotate relative to the housing 10 about a first preset direction AA, and the pin assembly 20 can rotate along with the rotating bracket 30 about the first preset direction AA. In addition, the pin assembly 20 can also rotate relative to the rotating bracket 30 about a second preset direction BB. Therefore, the pin assembly 20 can rotate relative to the housing 10 about the first preset direction AA and the second preset direction BB, thereby adjusting the position of the pin 21 in multiple dimensions. When inserting the pin 21 into the power strip, the user can rotate the rotating bracket 30 or / and the pin assembly 20 according to the distribution of the sockets on the power strip to adjust the position of the pin 21. This can adjust the position of the housing 10 on the socket after the pin 21 is inserted into the socket, so that the housing 10 clears the empty socket on the power strip. This prevents the housing 10 from blocking adjacent sockets after the pin 21 is inserted into the socket, and also prevents interference between the housing 10 and other electronic devices on the socket.

[0054] In addition, referring to FIG3 , taking the example of the first preset direction AA being parallel to the peripheral side surface 12 of the shell 10, when the power strip is placed vertically on a wall or table, etc., and the pin 21 needs to be inserted into the power strip, the pin assembly 20 can be rotated about the second preset direction BB so that the shell 10 can be parallel to the power strip when the pin 21 is inserted into the power strip, thereby increasing the contact area between the shell 10 and the power strip and making the connection more stable, thus preventing the plug from separating from the power strip and causing it to fall. It should also be noted that FIG1 to FIG3 only schematically illustrate the situation where the first preset direction AA is parallel to the peripheral side surface 12 of the shell 10; according to actual needs, the second preset direction BB can also be set to be parallel to the peripheral side surface 12 of the shell 10.

[0055] It should also be noted that when the first preset direction AA is parallel to the circumferential side surface 12 of the shell 10, the axial direction of the second rotating shaft 26 is parallel to the second preset direction BB; when the second preset direction BB is parallel to the circumferential side surface 12 of the shell 10, the axial direction of the second rotating shaft 26 is parallel to the first preset direction AA.

[0056] In some embodiments of the present application, a first mounting groove 11 is provided on the shell 10. The first mounting groove 11 extends along a third preset direction CC and passes through the shell 10 to form a first avoidance opening for the rotating bracket 30 to rotate. The third preset direction CC is perpendicular to the first preset direction AA.

[0057] Among them, the movable track of the rotating bracket 30 has a first preset position (as shown in Figures 1 and 10) and a second preset position (as shown in Figure 9). When the rotating bracket 30 is at the first preset position, the rotating bracket 30 is accommodated in the first mounting groove 11. When the rotating bracket 30 is at the second preset position, part of the rotating bracket 30 extends out of the first mounting groove 11 through the first avoidance opening. It should be noted that, as shown in Figure 1, when the rotating bracket 30 is at the first preset position, the rotating bracket 30 can be accommodated by the first mounting groove 11, which can reduce the overall volume of the plug and make the plug easy to carry and store. The first avoidance opening can provide a rotation space for the rotating bracket 30, thereby preventing the first mounting groove 11 from restricting the rotation of the rotating bracket 30.

[0058] Optionally, as shown in Figures 1 and 9, the first preset direction AA is parallel to the peripheral side surface 12 of the shell 10, and the rotating bracket 30 can rotate 360 ​​degrees around the first preset direction AA. The rotating bracket 30 rotates 90 degrees from the first preset position (as shown in Figure 1) to the second preset position (as shown in Figure 9).

[0059] In some embodiments of the present application, a second mounting slot 31 is provided on the rotating bracket 30. The second mounting slot 31 extends along a fourth preset direction DD and passes through the rotating bracket 30 to form a second avoidance opening for the pin assembly 20 to rotate. The fourth preset direction DD is perpendicular to the second preset direction BB.

[0060] The movable path of the pin assembly 20 has a third preset position (as shown in Figures 1 and 9) and a fourth preset position (as shown in Figure 10). When the pin assembly 20 is in the third preset position, the pin assembly 20 is accommodated in the second mounting slot 31. When the pin assembly 20 is in the fourth preset position, a portion of the pin assembly 20 extends out of the second mounting slot 31 through the second clearance opening. It should be noted that, as shown in Figure 1, when the pin assembly 20 is in the third preset position, the second mounting slot 31 can accommodate the pin assembly 20, further reducing the overall size of the plug and making it easier to carry and store. The second clearance opening provides rotational space for the pin assembly 20, thereby preventing the second mounting slot 31 from restricting the rotation of the pin assembly 20. It should also be noted that in Figures 1 and 10, the fourth preset direction DD is parallel to the third preset direction CC, while in Figure 9, the fourth preset direction DD is perpendicular to the third preset direction CC.

[0061] Optionally, as shown in Figures 1 and 10, the first preset direction AA is parallel to the peripheral side surface 12 of the shell 10, and the pin assembly 20 can rotate 180 degrees around the first preset direction AA. The pin assembly 20 rotates 90 degrees from the third preset position (as shown in Figure 1) to the fourth preset position (as shown in Figure 10). At this time, when the pin assembly 20 rotates to the fourth preset position, the pin assembly 20 abuts against the bottom wall of the second mounting groove 31 to prevent the pin 21 from continuing to rotate in the direction away from the third preset position.

[0062] In some embodiments of the present application, as shown in Figures 11 to 13, the housing 10 includes a main body 13 and a fixing bracket 14. The fixing bracket 14 is detachably connected to the main body 13 and has a first mounting groove 11. The fixing bracket 14 can be detachably connected to the main body 13 by means of a snap connection or a threaded connection. The rotating bracket 30 is mounted on the fixing bracket 14, and the fixing bracket 14 is configured to provide support for the rotating bracket 30.

[0063] Continuing to refer to Figures 11 to 13, in some embodiments of the present application, the first preset direction AA is parallel to the peripheral side surface 12 of the shell 10, the plug also includes a rotating assembly 40, the rotating assembly 40 includes a sleeve 41 and a first elastic piece 42, and a through hole 141 is provided on the side of the fixed bracket 14 close to the main body 13. The axial direction of the sleeve 41 is parallel to the first preset direction AA, the sleeve 41 extends into the through hole 141 and is connected to the rotating bracket 30, and the rotating bracket 30 is rotatably connected to the shell 10 around the first preset direction AA through the sleeve 41; the first elastic piece 42 is sleeved on the sleeve 41.

[0064] Among them, the inner side of the first elastic piece 42 is provided with a concave-convex structure 421 extending around the circumference of the sleeve 41, and the concave-convex structure 421 includes a concave portion and a convex portion arranged along the circumference of the sleeve 41, and the distance between the convex portion and the sleeve 41 is smaller than the distance between the concave portion and the sleeve 41, so that when the sleeve 41 rotates to different positions, the first elastic piece 42 provides the sleeve 41 with damping forces of different sizes, so that the sleeve 41 has an obvious sense of frustration during the rotation process. Therefore, by designing the concave-convex structure 421, the rotation position of the rotating bracket 30 can be positioned. For example, when the rotating bracket 30 is in the first preset position and the second preset position, the damping force of the first elastic piece 42 on the sleeve 41 is large, and when the rotating bracket 30 is in other positions, the damping force of the first elastic piece 42 on the sleeve 41 is small. Whether the rotating bracket 30 rotates to the first preset position and the second preset position can be determined based on the change in the damping force of the first elastic piece 42 on the sleeve 41. The positioning piece 43 can limit the first elastic piece 42 to prevent the first elastic piece 42 from moving axially along the sleeve 41 during use. The first elastic piece 42 can be made of elastic metal, elastic rubber or elastic plastic, etc., and this application does not make any specific restrictions.

The mounting plate is located on the side of the fixed bracket 14 away from the rotating bracket 30. The mounting plate is installed on the fixed bracket 14 and is arranged around the circumference of the positioning piece 43. The mounting plate is configured to fix the positioning piece 43 on the sleeve 41, thereby utilizing the positioning piece 43 to limit the first spring piece 42 to prevent the first spring piece 42 from moving axially along the sleeve 41 during use.

[0066] Continuing with Figures 11 to 13 , the rotating bracket 30 further includes an elastic bracket 32 ​​positioned within the second mounting slot 31. The elastic bracket 32 ​​includes second springs 321 positioned on either side of the pin assembly 20 along the second predetermined direction BB. The pin assembly 20 is sandwiched between the two second springs 321 and is rotationally coupled to the second springs 321 about the second predetermined direction BB via a rotating arm 33. The second springs 321 provide rotational resistance for the pin assembly 20, preventing it from rotating due to external forces during use. The second springs 321 can be made of materials such as elastic metal, elastic rubber, or elastic plastic, and this application does not impose any specific limitations.

[0067] Continuing with Figures 11 to 13 , in some embodiments of the present application, the plug further includes a circuit board 51 and a conductive wire 52.

The other end of the conductive wire 52 passes through the rotating arm 33 and is electrically connected to the pin 21. The circuit board 51 can be electrically connected to the device to be charged via a data cable or other connecting line, thereby achieving an electrical connection between the pin 21 and the device to be charged. The circuit board 51 can be a single-sided board, a double-sided board, or a multi-layer board. This application does not specifically limit the type, model, or size of the circuit board 51.

[0068] In some embodiments of the present application, the pin assembly 20 further includes a mounting bracket 22, the pin 21 is mounted on the mounting bracket 22, and the mounting bracket 22 is rotatably connected to the rotating bracket 30 around the second preset direction BB to switch between the third preset position and the fourth preset position.

[0069] In some embodiments of the present application, the pin assembly 20 further includes a silicone base 23, which is mounted on a side of the mounting bracket 22 near the rotating bracket 30. The silicone base 23 acts as an insulator to prevent short circuits between metal components on the mounting bracket 22 and the conductive wire 52. The silicone base 23 and the mounting bracket 22 can be integrally injection molded, or the silicone base 23 can be fixed to the mounting bracket 22 by gluing.
