[0047] As Figures 1 to 14As shown, the double-plug charger provided by the embodiment includes a shell 1 and a plug assembly 2, the shell 1 is provided with a receiving cavity, and the plug assembly 2 is movably installed in the receiving cavity along a first direction. The plug assembly 2 includes a plug base 21, a mule shoe 22 and a parallel plug 23, wherein the mule shoe 22 is arranged at one end of the plug base 21 along the first direction, the parallel plug 23 is arranged at the other end of the plug base 21 along the first direction, and the mule shoe 22 and the parallel plug 23 are not communicated with each other and are respectively used for connecting with different types of sockets. Specifically, the mule shoe 22 is suitable for being inserted into the inverted mule hole of the common three-hole socket, and the parallel plug 23 is suitable for being inserted into the common two-hole socket. The plug assembly 2 of the embodiment has a first position and a second position, when the plug assembly 2 moves to the first position along the first direction, the mule shoe 22 protrudes out of the shell 1, at this time, the mule shoe 22 can be inserted into the three-hole socket to realize the charging function of the charger; when the plug assembly 2 moves to the second position along the first direction, the parallel plug 23 protrudes out of the shell 1, at this time, the parallel plug 23 can be inserted into the two-hole socket to realize the charging function of the charger. The double-plug charger of the embodiment protrudes different plugs according to different application scenarios, when the two-hole socket is available, the parallel plug 23 is protruded, when the two-hole socket is used and the three-hole socket is idle, the mule shoe 22 is protruded, so that the double-plug charger can be applied to both the two-hole socket and the three-hole socket, and has simple structure, convenient operation and reliable use. In the embodiment, the first direction is specifically the front-rear direction of the shell 1.

[0048] Further, when the mule shoe 22 protrudes out of the shell 1, the parallel plug 23 can be retracted into the shell 1; when the parallel plug 23 protrudes out of the shell 1, the mule shoe 22 can be retracted into the shell 1. In this way, the unused plug can be prevented from being exposed outside the charger during charging, so that the mule shoe 22 and the parallel plug 23 can be connected with the socket only by selection, thereby improving the safety and reliability of the charger; and the above arrangement also makes the appearance of the charger more neat, facilitating storage and carrying. Specifically, one end of the shell 1 close to the mule shoe 22 is provided with a mule hole 101, when the mule shoe 22 needs to be used, it can protrude out of the mule hole 101, and when the mule shoe 22 does not need to be used, it can be retracted into the inside of the mule hole 101; at the same time, one end of the shell 1 close to the parallel plug 23 is provided with a parallel hole 102, to facilitate the parallel plug 23 to protrude out of or retract into the parallel hole 102. In this way, the use convenience and safety of the charger are effectively improved, so that the corresponding plug can be retracted into the hole when not in use, avoiding damage caused by being exposed outside, reducing the occupied space and facilitating carrying.

[0049] In the embodiment, the shell 1 is further provided with a conductive spring 3, and the conductive spring 3 is provided with two first conductive terminals 31 and two second conductive terminals 32. The plug base 21 is provided with two third conductive terminals 213 and two fourth conductive terminals 214, wherein each third conductive terminal 213 is electrically connected with the eight-shaped plug 22, and each fourth conductive terminal 214 is electrically connected with the parallel plug 23. When the plug assembly 2 moves to the first position, the two first conductive terminals 31 and the two third conductive terminals 213 are electrically connected one by one, so as to realize the electrical conduction between the eight-shaped plug 22 and the conductive spring 3, and facilitate charging through the eight-shaped plug 22 inserted into the three-hole socket; when the plug assembly 2 moves to the second position, the two second conductive terminals 32 and the two fourth conductive terminals 214 are electrically connected one by one, so as to realize the electrical conduction between the parallel plug 23 and the conductive spring 3, and facilitate charging through the parallel plug 23 inserted into the two-hole socket. Optionally, the two first conductive terminals 31 are arranged along the second direction in sequence, the two second conductive terminals 32 are arranged along the second direction in sequence, the two third conductive terminals 213 are arranged along the second direction in sequence, and the two fourth conductive terminals 214 are arranged along the second direction in sequence. In the embodiment, the second direction is perpendicular to the first direction, specifically the width direction of the shell 1.

[0050] Further, the shell 1 is further provided with a circuit board 4, and the circuit board 4 is provided with two fifth conductive terminals 45. The circuit board 4 is electrically connected with the conductive spring 3 through the two fifth conductive terminals 45, so that when the plug assembly 2 is located at the first position, the eight-shaped plug 22 is electrically connected with the circuit board 4, and when the plug assembly 2 is located at the second position, the parallel plug 23 is electrically connected with the circuit board 4. Specifically, the circuit board 4 is provided with a transformer element 41, a voltage stabilizing element 42, a fuse 43 and a USB interface 44, and the current on the eight-shaped plug 22 or the parallel plug 23 flows to the circuit board 4 through the conductive spring 3, and then flows to the USB interface 44 through the transformer element 41, the voltage stabilizing element 42 and the fuse 43 in sequence, so as to realize the electrical conduction between the eight-shaped plug 22 or the parallel plug 23 and the USB interface 44. In addition, the shell 1 is further provided with a USB interface reserved hole 17 to facilitate the insertion of the USB line, and the other end of the USB line is connected with an electronic product.

[0051] To fix the position of the plug assembly 2, in the embodiment, the inner wall of the shell 1 is provided with a first limiting slot 111 and a second limiting slot 112, and the plug base 21 is provided with a first elastic member 211 and a second elastic member 212, wherein the first elastic member 211 is used to be engaged with the first limiting slot 111 to limit the plug assembly 2 in the first position, and the second elastic member 212 is used to be engaged with the second limiting slot 112 to limit the plug assembly 2 in the second position. Meanwhile, the side wall of the shell 1 is also provided with a first push piece 121 opposite to the first limiting slot 111 and a second push piece 122 opposite to the second limiting slot 112, wherein the first push piece 121 can move along the inside and outside of the shell 1 after being pressed, so as to push the first elastic member 211 out of the first limiting slot 111 to unlock the plug assembly 2 in the first position, and the second push piece 122 can move along the inside and outside of the shell 1 after being pressed, so as to push the second elastic member 212 out of the second limiting slot 112 to unlock the plug assembly 2 in the second position.

[0052] Specifically, the working process of the embodiment is as follows: since the parallel plug 23 is used frequently, usually, the plug assembly 2 is located in the second position, at this time, the parallel plug 23 extends out of the shell 1, the second elastic member 212 is engaged in the second limiting slot 112, so that the plug assembly 2 is locked in the second position and cannot continue to move in the shell 1, thus ensuring the reliability of the plug-in of the parallel plug 23 and the two-hole socket. When the splayed plug 22 needs to be used, the second elastic member 212 is only needed to be pressed to be separated from the second limiting slot 112, so as to push the plug assembly 2 to move in the first direction to the first position, at this time, the splayed plug 22 extends out of the shell 1, the first elastic member 211 is engaged in the first limiting slot 111, so that the plug assembly 2 is locked in the first position and cannot continue to move in the shell 1, thus ensuring the reliability of the plug-in of the splayed plug 22 and the three-hole socket. When the parallel plug 23 needs to be used again, the first elastic member 211 is only needed to be pressed to be separated from the first limiting slot 111, so as to push the plug assembly 2 to move in the first direction to the second position.

[0053] Further, the first limiting groove 111 and the second limiting groove 112 are both arranged through the side wall of the shell 1, the first pressing piece 121 is located at one side of the first limiting groove 111 close to the outer wall of the shell 1, and the second pressing piece 122 is located at one side of the second limiting groove 112 close to the outer wall of the shell 1. Optionally, the first pressing piece 121 and the second pressing piece 122 are the same in structure and both include a fixed part and a movable part, the fixed part is fixedly connected with the side wall of the shell 1, and the outer periphery of the movable part is spaced from the side wall of the shell 1 to enable the movable part to move to a certain extent inside and outside the shell 1, and the movable part can be pressed inward to realize unlocking of the plug-in piece assembly 2. In the embodiment, the first pressing piece 121 and the second pressing piece 122 are preferably integrally formed with the shell 1, which is simple in structure, easy to process and reliable in use.

[0054] In the embodiment, when the first elastic piece 211 is clamped in the first limiting groove 111, the second elastic piece 212 is compressed and abuts against the surface of the plug-in piece base 21, and when the second elastic piece 212 is clamped in the second limiting groove 112, the first elastic piece 211 is compressed and abuts against the surface of the plug-in piece base 21. To reduce the influence of long-term compression of the first elastic piece 211 and the second elastic piece 212 on their service life, the third limiting groove 113 is further arranged in the embodiment. Specifically, the first limiting groove 111 and the second limiting groove 112 are arranged in sequence in the first direction on the side wall of the shell 1, and the third limiting groove 113 is arranged between the first limiting groove 111 and the second limiting groove 112; meanwhile, the first elastic piece 211 and the second elastic piece 212 are also arranged in sequence in the first direction on the plug-in piece base 21. When the plug-in piece assembly 2 is in the first position, the first elastic piece 211 is located in the first limiting groove 111, and the second elastic piece 212 is located in the third limiting groove 113, so as to provide a certain accommodation space for the second elastic piece 212 and avoid damage to the second elastic piece 212 due to long-term compression and affect the resilience of the second elastic piece 212; when the plug-in piece assembly 2 is in the second position, the second elastic piece 212 is located in the second limiting groove 112, and the first elastic piece 211 is located in the third limiting groove 113, so as to provide a certain accommodation space for the first elastic piece 211 and avoid damage to the first elastic piece 211 due to long-term compression and affect the resilience of the first elastic piece 211. Of course, to facilitate the first elastic piece 211 and the second elastic piece 212 to smoothly escape from the third limiting groove 113 during movement of the plug-in piece assembly 2, a guide slide can be arranged at both ends of the third limiting groove 113, or a corresponding guide structure can be arranged on the first elastic piece 211 and the second elastic piece 212, or the third limiting groove 113 also penetrates through the side wall of the shell 1, and a corresponding pressing piece structure is arranged outside the third limiting groove 113, and the like, which are not limited in the embodiment.

[0055] Optionally, in the embodiment, the first elastic member 211 is a first limiting elastic sheet, and the second elastic member 212 is a second limiting elastic sheet. One end of the first limiting elastic sheet along the first direction is fixedly connected with the plug base 21, and the other end along the first direction is suspended relative to the surface of the plug base 21. When the plug assembly 2 slides in the shell 1, the suspended end of the first limiting elastic sheet is extruded by the inner wall of the shell 1 and is bent towards the surface of the plug base 21. When the first limiting elastic sheet enters the first limiting groove 111, the suspended end of the first limiting elastic sheet is bounced outwards and can abut against the groove wall of the first limiting groove 111. Similarly, one end of the second limiting elastic sheet along the first direction is fixedly connected with the plug base 21, and the other end along the first direction is suspended relative to the surface of the plug base 21. When the plug assembly 2 slides in the shell 1, the suspended end of the second limiting elastic sheet is extruded by the inner wall of the shell 1 and is bent towards the surface of the plug base 21. When the second limiting elastic sheet enters the second limiting groove 112, the suspended end of the second limiting elastic sheet is bounced outwards and can abut against the groove wall of the second limiting groove 112. Specifically, in the embodiment, the suspended end of the first limiting elastic sheet and the suspended end of the second limiting elastic sheet are close to each other, and the fixed end of the first limiting elastic sheet and the fixed end of the second limiting elastic sheet are far away from each other.

[0056] As a preference, in the embodiment, the third limiting groove 113 is a blind groove (i.e. a groove not penetrating through the side wall of the shell 1) arranged on the inner wall of the shell 1. The third limiting groove 113 can not only accommodate the first elastic member 211 and the second elastic member 212, but also limit the first elastic member 211 and the second elastic member 212. Specifically, as shown in FIGS. 7 and 8, the third limiting groove 113 is arranged on the inner wall of the shell 1, and the first limiting elastic sheet and the second limiting elastic sheet are accommodated in the third limiting groove 113. Figure 8As shown, when the plug assembly 2 is inserted into the shell 1 from left to right along the first direction, the second limiting spring first enters the first limiting slot 111; then the second limiting spring continues to move into the third limiting slot 113, at this time the first limiting spring enters the first limiting slot 111, and the overhanging end of the first limiting spring abuts against the right side wall of the first limiting slot 111, so that the plug assembly 2 cannot continue to move to the right, and at the same time the overhanging end of the second limiting spring abuts against the left side wall of the third limiting slot 113, so that the plug assembly 2 also cannot move to the left, so that the plug assembly 2 is locked at the first position, ensuring that the eight-shaped plug 22 cannot retract into the shell 1 during the process of being plugged with the three-hole socket; then by pressing the first push piece 121 to make the first limiting spring out of the first limiting slot 111, and pushing the plug assembly 2 to continue to move to the right, until the second limiting spring enters the second limiting slot 112 and the first limiting spring enters the third limiting slot 113, at this time the overhanging end of the second limiting spring abuts against the left side wall of the second limiting slot 112, so that the plug assembly 2 cannot move to the left, and at the same time the overhanging end of the first limiting spring abuts against the right side wall of the third limiting slot 113, so that the plug assembly 2 also cannot continue to move to the right, so that the plug assembly 2 is locked at the second position, ensuring that the parallel plug 23 cannot retract into the shell 1 during the process of being plugged with the socket.

[0057] Of course, in other embodiments, the first elastic member 211 and the second elastic member 212 can also adopt other elastic limiting members, such as spring positioning pins, which are pushed into the first limiting slot 111 or the second limiting slot 112 by springs, and can also achieve the locking of the position of the plug assembly 2.

Furthermore, the first sliding rail 131 effectively improves the stability of the plug assembly 2 moving along the first direction. Preferably, the sliding block 215 is a sliding strip extending along the first direction, so as to better slide with the first sliding rail 131. Of course, in other embodiments, the sliding block 215 can be arranged on the inner wall of the shell 1, and the first sliding rail 131 can be arranged on the plug base 21, and the sliding connection between the plug base 21 and the shell 1 can also be achieved. Alternatively, the inner wall of the shell 1 is further provided with a second sliding rail 132 extending along the first direction, and the circuit board 4 is in sliding connection with the second sliding rail 132. In this way, the circuit board 4 is guided and limited, and can be installed in the shell 1 more accurately and smoothly, the assembling efficiency is improved, and the circuit board 4 is convenient to disassemble and overhaul.

[0059] In the embodiment, the shell 1 is further provided with a support plate 14 for the convenience of fixing the conductive spring 3 in the shell 1, and the conductive spring 3 is fixed on the support plate 14. Here, the support plate 14 can be fixedly connected in the shell 1, or integrally manufactured with the shell 1, or detachably installed in the shell 1. Preferably, in the embodiment, the inner wall of the shell 1 is provided with a third sliding rail extending along the first direction, and the support plate 14 is slidably installed in the shell 1 through the third sliding rail. In this way, the support plate 14 is separately manufactured, the manufacturing difficulty is reduced, and the conductive spring 3 is convenient to disassemble and overhaul.
