[0033] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0034] In the related art, the European standard travel charger conversion plug is generally composed of a plug body, a mounting seat and a plug pin. The plug pin is installed on the mounting seat, and the mounting seat is installed on the plug body. Such a design will cause the mounting seat and the plug pin to occupy a larger volume, thus causing the plug product to be thick and large in overall volume.

[0035] For the above situation, please see Figure 1-Figure 4 The present application proposes a plug 1 , which includes a housing 10 , a lifting platform 20 and a first pin assembly 30 .

[0036] The housing 10 has a receiving cavity (not shown in the figure), and is provided with an opening 11 communicating with the receiving cavity and a transfer hole 12 for other plugs to be plugged in. When the plug of the electric device carried by the user cannot match the local socket, the plug of the electric device can be plugged into the transfer hole 12 to complete the conversion between the plug of the electric device and the local socket, thereby realizing the power supply function. Among them, the transfer hole 12 can be various types such as a USB socket, a Chinese standard double socket or a Chinese standard three socket.

[0037] The lifting platform 20 is disposed on the housing 10, and the lifting platform 20 can slide relative to the housing 10 along the axial direction of the opening 11 to enter and exit the accommodating cavity through the opening 11; the first pin assembly 30 is disposed on the lifting platform 20, and the first pin assembly 30 includes a plurality of first pins 31, and the first pins 31 are rotatably connected to the lifting platform 20 to switch between the unfolded position and the stored position. For example, the first pin assembly 30 includes two first pins 31 to form a two-pin plug, and the two first pins 31 are respectively used to connect the live wire and the neutral wire, or the first pin assembly 30 includes three first pins 31 to form a three-pin plug, and the three first pins 31 are respectively used to connect the live wire, the neutral wire and the ground wire.

[0038] Among them, when the plug 1 in this embodiment is in use, the lifting platform 20 can be pushed out of the accommodating cavity first, and then the first pin 31 can be rotated so that the first pin 31 is rotated to a state of extending axially along the opening 11, and then it can be inserted into the socket for normal power supply. The lifting platform 20 and the first pin assembly 30 can jointly form a European standard pin.

[0039] Exemplarily, the housing 10 has a receiving groove 13 corresponding to the first pins 31, and the first pins 31 can be received in the receiving groove 13. Alternatively, the receiving groove 13 is provided on the lifting platform 20. Alternatively, the housing 10 and the lifting platform 20 are provided with a groove body. When the lifting platform 20 enters the accommodating cavity, the lifting platform 20 docks with the groove body on the housing 10, thereby forming a complete receiving groove 13, so that the first pins 31 can be completely received in the receiving groove 13. The receiving groove 13 is used to receive the first pin 31 when the first pin 31 is in the receiving position; when the first pin 31 is in the extended position, the first pin 31 extends along the axial direction of the opening 11, and the head end of the first pin 31 is located outside the receiving groove 13.

[0040] It should be noted that, in the embodiment of the present application, the plurality of first pins 31 are folded and stored in the storage groove 13 of the lifting platform 20 and / or the shell 10, and the lifting platform 20 slides along the axial direction of the opening 11 so as to be stored in the accommodating cavity of the shell 10, thereby shortening the depth of the first pin assembly 30 and the lifting platform 20 sunk into the shell 10, so that the plug 1 itself is lighter and thinner, and easier to carry.

[0041] In some embodiments, the first pin assembly 30 includes a conductive electrode sheet 33 and two first pins 31, and the two first pins 31, the conductive electrode sheet 33 and the lifting platform 20 together form a 3-pin European plug. In the related art, most European conversion plugs use a low-power 2-pin European plug, thereby limiting the high-power power supply when using electricity; however, in the embodiment of the present application, the two first pins 31, the conductive electrode sheet 33 and the lifting platform 20 together form a 3-pin European plug, which is convenient for users to obtain high-power power.

[0042] See also Figure 5 In some embodiments of the present application, the adapter hole 12 and the opening 11 are opened on opposite sides of the shell 10, the lifting platform 20 has an installation cavity (not shown in the figure), and the plug 1 also includes a jack module 70, and the jack module 70 has a slot (not shown in the figure) connected to the adapter hole 12, and the slot is used for inserting the pins of other plugs. The user can insert the pins of the electrical device into the slot through the adapter hole 12, and then use the plug 1 to draw power for the electrical device.

[0043] Among them, when the lifting platform 20 is located in the accommodating cavity, the jack module 70 can be completely located in the installation cavity, or part of the jack module 70 is located in the installation cavity; when the lifting platform 20 extends out of the accommodating cavity, the jack module 70 is located in the accommodating cavity, thereby making it possible to make more full use of the space in the lifting platform 20, that is, to improve the space utilization rate in the shell 10, reduce the space occupied by the plug 1 when it is stored, and facilitate users to carry it out.

[0044] See also Figure 4-Figure 7In some embodiments of the present application, the plug 1 also includes a control circuit board (not shown in the figure) and a conductive member 21, the control circuit board is arranged on the shell 10; the conductive member 21 is arranged on the lifting platform 20 and is electrically connected to the control circuit board, the control circuit board is used to be electrically connected to an external power supply, and can transfer the current of the external power supply to the conductive member 21.

[0045] Among them, the tail end of the first pin 31 is connected to the power connection part 311. When the first pin 31 is in the expanded position, the power connection part 311 is electrically connected to the conductive member 21, so that the current on the conductive member 21 can be transmitted to the power connection part 311 and the first pin 31; when the first pin 31 is in the stored position, the power connection part 311 is separated from the conductive member 21, thereby ensuring the power-off safety of the first pin 31.

[0046] For further information, see Figure 6-Figure 7 In some embodiments of the present application, the conductive member 21 has a slot arranged on one side facing the power connection portion 311. When the first pin 31 rotates from the storage position to the deployment position, the first pin 31 drives the power connection portion 311 to rotate and enter the slot. The slot can be engaged with the power connection portion 311, thereby ensuring a stable contact between the first pin 31 and the conductive member 21 and reducing the shaking of the first pin 31.

[0047] For further information, please see Figure 6-Figure 7 In some embodiments of the present application, the first pin assembly 30 also includes a rotating shaft 32, and the first pin 31 is rotatably connected to the lifting platform 20 via the rotating shaft 32. The circumferential side of the rotating shaft 32 has a contact plane 321. When the first pin 31 is rotated to the unfolded position, the contact plane 321 abuts against the lifting platform 20, that is, the contact plane 321 on the circumferential side of the rotating shaft 32 abuts against the surface of the lifting platform 20, thereby reducing unstable shaking of the first pin 31 when in the unfolded position.

[0048] In some embodiments, Figure 7 As shown, a protrusion 322 is provided on the circumferential side of the rotating shaft 32. The protrusion 322 has a first surface and a second surface arranged adjacent to each other. Both the first surface and the second surface can be used to abut against the lifting platform 20. In other words, the first surface and the second surface are both abutting planes 321, and the protrusion 322 is formed by two abutting planes 321. When the first pin 31 rotates to the unfolded position, the first surface abuts against the lifting platform 20. When the first pin 31 rotates to the storage position, the second surface abuts against the lifting platform 20, thereby increasing the stability of the first pin 31 at any position. At the same time, the first surface and the second surface are connected by an arc surface to reduce the friction between the rotating shaft 32 and the lifting platform 20, so that the user can push the rotating shaft 32 to rotate.

[0049] See also Figure 8In some embodiments of the present application, the shell 10 includes a limiting bracket 14 arranged in the accommodating cavity, the extending direction of the limiting bracket 14 is parallel to the axial direction of the opening 11, and both ends of the limiting bracket 14 are provided with limiting portions 141, that is, both ends of the limiting bracket 14 along the first direction L1 are provided with limiting portions 141, and the first direction L1 is parallel to the axial direction of the opening 11; the limiting bracket 14 includes a sliding portion 142, and the sliding portion 142 is located between the limiting portions 141 at both ends.

[0050] like Figure 6 As shown, the lifting platform 20 includes a main body 24 and a base 23 connected to each other, and the first pin assembly 30 and the base 23 are arranged on opposite sides of the main body 24. Figure 8-Figure 10 As shown, the plug 1 further includes a locking member 42 connected to the base 23, and the locking member 42 is movably connected to the housing 10 and the sliding portion 142 of the limiting bracket 14. When the locking member 42 moves relative to the sliding portion 142 along the first direction L1, the locking member 42 can drive the lifting platform 20 to move along the first direction L1 as a whole. At the same time, the locking member 42 can also be connected to the limiting portion 141 of the limiting bracket 14. When the locking member 42 moves from the sliding portion 142 to the limiting portion 141, the locking member 42 abuts against the limiting portion 141, and the locking member 42 and the limiting bracket 14 are in a locked state.

[0051] Specifically, taking the sliding portion 142 having the first limit step and the second limit step at both ends as an example, when the locking member 42 abuts against the first limit step, the lifting platform 20 is locked in the accommodating cavity, and when the locking member abuts against the second limit step, the lifting platform 20 is locked outside the accommodating cavity.

[0052] For example, Figure 8 As shown, Figure 8 1 is a schematic diagram of the structure of the limiting bracket 14, the sliding portion 142 and the limiting portion 141 have a height difference in the second direction L2, and the second direction L2 is perpendicular to the first direction L1. Figure 9-10 As shown, Fig. 9 is a schematic diagram of the installation structure of the locking member 42 and the base 23, Fig.10The figure mainly shows the installation diagram of the limit bracket 14, the locking member 42 and the base 23. The locking member 42 can move on the sliding part along the first direction L1. When the locking member 42 moves to the end of the sliding part 142, the locking member 42 can move to the limit part 141 along the second direction L2. Since the limit part 141 and the sliding part 142 have a height difference in the second direction L2, the limit part 141 blocks the locking member 42 from continuing to slide along the first direction L1, that is, the limit part 141 locks the locking member 42. Similarly, if the locking member 42 is to be unlocked, a force along the second direction L2 can be applied to the locking member 42 to make the locking member 42 move relative to the limit part 141 along the second direction L2, thereby unlocking the locking member 42 and the limit part 141. It can be understood that the locking member 42 is movably connected to the shell 10 along the first direction L1 and the second direction L2. For example, the locking member 42 can first move along the second direction L2 to unlock the limiting portion 141, and then the locking member 42 moves along the first direction L1 on the sliding portion 142 to drive the lifting platform 20 to enter and exit the accommodating cavity.

[0053] For further information, see Fig. 9 In some embodiments of the present application, the plug 1 also includes an elastic member 43 extending along the second direction L2, one end of the elastic member 43 is connected to the locking member 42, and the other end of the elastic member 43 is connected to the base 23 of the lifting platform 20, and the elastic member 43 is used to reset the locking member 42 along the second direction L2.

[0054] Specifically, when the lifting platform 20 slides from the inside of the accommodating cavity to the outside of the accommodating cavity, the locking member 42 first abuts against the first limiting step, and then an external force along the second direction L2 is applied to the locking member 42. At this time, the elastic member 43 is subjected to the force of the locking member 42, so that the elastic member 43 is in a deformed state, and the locking member 42 moves along the second direction L2 to unlock the limiting portion 141; then an external force along the first direction L1 is applied to the locking member 42, so that the locking member 42 slides along the first direction L1 on the sliding portion 142 until the locking member 42 slides to the end of the sliding portion 142 along the first direction L1. At this time, the elastic member 43 is not subjected to force or the force on the elastic member 43 is reduced, and the elastic member 43 can drive the locking member 42 to move along the second direction L2 and abut against the second limiting step to achieve the locking of the locking member 42 and the limiting portion 141.

[0055] See also Figure 11-Figure 12 In some embodiments of the present application, the plug 1 further includes a plurality of second pin assemblies 50 (such as Figure 3-4 As shown), each second pin assembly 50 includes a plurality of second pins 51. The second pins 51 can slide relative to the housing 10 along a first direction L1 to enter and exit the accommodating cavity. The first direction L1 is parallel to the axial direction of the opening 11.

[0056] For example, Fig.12 As shown, the plurality of second pin assemblies 50 include a British standard pin assembly, a US standard pin assembly and a Chinese standard pin assembly, the British standard pin assembly includes three British standard pins 511 (i.e., the second pins 51), the US standard pin assembly includes three US standard pins 512 (i.e., the second pins 51), and the Chinese standard pin assembly includes three Chinese standard pins 513 (i.e., the second pins 51). Specifically, the three second pin assemblies 50 are all located on one side of the lifting platform 20, and the setting positions of the grounding electrode pins in the three second pin assemblies 50 are all spaced apart on the same straight line, wherein the US standard pin 512 assembly and the Chinese standard pin 513 assembly are arranged in parallel and spaced apart, and the live wire pin and the neutral wire pin in the British standard pin assembly are respectively located between the US standard pin assembly and the Chinese standard pin assembly, thereby not only meeting the safety requirements of the British standard plug, but also ensuring the safety value requirements of any one of the US standard pin 512 and the Chinese standard pin 513 to the edge of the shell.

[0057] The number of the limiting brackets 14 can be set in one-to-one correspondence with the number of the first pin assemblies 30 and the second pin assemblies 50. In some embodiments, for example Fig.11 As shown, each second pin assembly 50 also includes a supporting plate 52 and a button 53, the button 53 includes a button 53 body and a lock 532 that are connected to each other, and multiple second pins 51 are fixed to the supporting plate 52, the button 53 body is slidably connected to the supporting plate 52 along the second direction L2, and the lock 532 of the button 53 is movably connected to a limiting bracket 14, and the lock 532 is used to lock or unlock with the limiting portion 141.

[0058] At the same time, Fig. 9As shown, each second pin assembly 50 further includes a spring 533 , the supporting plate 52 includes a fixing portion 521 , the spring 533 is disposed between the button 53 body and the fixing portion 521 , and the spring 533 extends along the second direction L2 . When the plurality of second pins 51 are located in the accommodating cavity and the lock buckle 532 is locked with the limiting portion 141 of the limiting bracket 14, an external force is applied to the button 53 body along the second direction L2, and the button 53 body can first compress the spring 533, and the button 53 slides along the second direction L2 relative to the supporting plate 52. At this time, the lock buckle 532 and the limiting portion 141 of the limiting bracket 14 are unlocked, and the button 53 body can drive the supporting plate 52 and the second pins 51 to slide along the first direction L1 relative to the limiting bracket 14, thereby pushing the plurality of second pins 51 out of the accommodating cavity along the first direction L1; when the external force disappears, the button 53 body moves along the second direction L2 under the elastic force of the spring 533, so that the lock buckle 532 and the limiting portion 141 of the limiting bracket 14 are locked again to fix the second pins 51 outside the accommodating cavity. Among them, the button 53 body can be provided with a slide groove 534 extending along the second direction L2, and the supporting plate 52 can also include a slider 522. The slide groove 534 is slidably connected to the slider 522 along the second direction L2. The slide groove 534 defines a movable trajectory for the button 53 body along the second direction L2, thereby preventing the button 53 from sliding too far or too far relative to the supporting plate 52.

[0059] For further information, see Figure 12-13 In some embodiments of the present application, the shell 10 includes a first side portion, and the opening 11 is located on the first side portion; the plug 1 also includes a limiting structure 60, which is arranged on the first side portion, and the limiting structure 60 can slide along the second direction L2 relative to the shell 10, and the limiting structure 60 is used to prevent the lifting platform 20 or the second pin 51 from extending out of the accommodating cavity along the first direction L1, and the second direction L2 is perpendicular to the first direction L1.

[0060] When the lifting platform 20 extends out of the accommodating cavity, the limiting structure 60 blocks the second pins 51 in the plurality of second pin assemblies 50 from extending out of the accommodating cavity; when one of the plurality of second pins 51 extends out of the accommodating cavity, the limiting structure 60 blocks the lifting platform 20 and the other second pins 51 from extending out of the accommodating cavity. For example, the plurality of second pins 51 include British standard pins 511, American standard pins 512, and Chinese standard pins 513. When any one of the lifting platform 20, British standard pins 511, American standard pins 512, and Chinese standard pins 513 extends out of the accommodating cavity, the limiting structure 60 slides to a position that blocks the other three from extending out of the accommodating cavity. At this time, even if the other three are moved again, the other three will not extend out of the accommodating cavity, thereby realizing the locking and limiting of the other three pins or the lifting platform 20 by the limiting structure 60.

[0061] For further information, see Figure 13-14In some embodiments of the present application, a limiting groove 22 (such as Figure 2 As shown); the limiting structure 60 includes a first part 61 and a second part 62. When the lifting platform 20 extends out of the accommodating cavity, the first part 61 is used to block a second pin 51 adjacent to the lifting platform 20 from extending out of the accommodating cavity. When the lifting platform 20 does not extend out of the accommodating cavity, the first part 61 is used to extend into the limiting groove 22 to block the lifting platform 20.

[0062] The second part 62 is connected to the first part 61 through an elastic arm 63, and the second part 62 is spaced apart from the first part 61. The lifting platform 20 is located on a side of the first part 61 away from the second part 62. One second pin 51 is located between the first part 61 and the second part 62, and the other second pins 51 are located on a side of the second part 62 away from the first part 61. When a part of the second pins 51 extend out of the accommodating cavity, the first part 61 extends into the limiting groove 22 to block the lifting platform 20, and the second part 62 blocks the other part of the second pins 51 from extending out of the accommodating cavity.

[0063] Specifically, when the second pin 51 between the first portion 61 and the second portion 62 extends out of the accommodation cavity (eg Fig.13 As shown in the figure, the second pin 51 can push the first part 61 to move and enter the limiting groove 22, and the second pin 51 can also push the second part 62 to move, thereby blocking other second pins 51; when a second pin 51 located on the side of the second part 62 away from the first part 61 extends out of the accommodating cavity, the second pin 51 can push the limiting structure 60 to move, thereby blocking the lifting platform 20 and other second pins 51.

[0064] For example, Figure 12-13As shown, the second pin assembly 50 includes a British standard pin assembly, a US standard pin assembly and a Chinese standard pin assembly, the plurality of second pins 51 include a British standard pin 511, a US standard pin 512, and a Chinese standard pin 513, the first part 61 includes a first area 612 away from the lifting platform 20, the second part 62 includes a second area 622, a third area 623 and a fourth area 624, when the lifting platform 20 extends out of the accommodating cavity, the side wall of the lifting platform 20 pushes the first part 61 to slide in a direction close to the second part 62, the first area 612 of the first part 61 slides to a position blocking the British standard pin 511, the third area 623 of the second part 62 slides to a position blocking the US standard pin 512, and the fourth area 624 slides to a position blocking the Chinese standard pin 513 When the British standard plug 511 extends out of the accommodating cavity, the first part 61 extends into the limiting groove 22 to block the lifting platform 20, the third area 623 slides to a position to block the American standard plug 512, and the fourth area 624 slides to a position to block the Chinese standard plug 513; when the American standard plug 512 extends out of the accommodating cavity, the first part 61 extends into the limiting groove 22 to block the lifting platform 20, the second area 622 slides to a position to block the British standard plug 511, and the fourth area 624 slides to a position to block the Chinese standard plug 513; when the Chinese standard plug 513 extends out of the accommodating cavity, the first part 61 extends into the limiting groove 22 to block the lifting platform 20, the second area 622 slides to a position to block the British standard plug 511, and the third area 623 slides to a position to block the American standard pin 512.

[0065] In some embodiments, any of the second area 622, the third area 623 and the fourth area 624 in the second part 62 may include a limiting hole, and the limiting hole is used to allow a second pin 51 to extend out of the accommodating cavity. That is, when a second pin 51 corresponding to the limiting hole extends out of the accommodating cavity, the second pin 51 can pass through the limiting hole, so that the position of the second part 62 is fixed, thereby allowing other second pins 51 to be blocked by other areas of the second part 62.

[0066] It should be noted that, taking the distance that the first part 61 extends into the limiting groove 22 as A1 and the interval distance between the first part 61 and the second part 62 as A2 as an example, A1>A2, when the lifting platform 20 extends out of the accommodating cavity, the side wall of the lifting platform 20 pushes the first part 61 to slide toward the direction close to the second part 62, and then the first area 612 of the first part 61 can block the British standard pin 511, and the movement of the first part 61 will also drive the second part 62 to move in the same direction, so that the second part 62 blocks the American standard pin 512 and the Chinese standard pin 513.

[0067] For further information, see Figure 15-16In some embodiments of the present application, the limiting groove 22 has a bevel groove wall 221, and the first part 61 has a first bevel 613 corresponding to the bevel groove wall 221. When the first part 61 extends into the limiting groove 22, the first bevel 613 contacts the bevel groove wall 221. The first bevel 613 and the bevel groove wall 221 can both play a guiding role to facilitate the first part 61 to enter and exit the limiting groove 22.

[0068] And / or, in some embodiments, a second inclined surface 614 is provided on the side of the first portion 61 away from the lifting platform 20, and the second inclined surface 614 is used to contact the head end of the second pin 51, and a third inclined surface 625 is provided on the second portion 62, and the third inclined surface 625 is used to contact the head end of the second pin 51. The second inclined surface 614 and the third inclined surface 625 can both play a guiding role, so that the second pin 51 can push the first portion 61 or the second portion 62 out of the accommodating cavity.

[0069] And / or, in some embodiments, the head end of the second pin 51 is provided with a guiding slope, and the guiding slope is used to contact the first part 61 and the second part 62, so that the second pin 51 pushes the first part 61 or the second part 62 out of the accommodating cavity.
