[0050] Embodiment one

[0051] As Figures 1 to 14As shown, the embodiment provides a double-prong charger, which includes a shell 1 and a prong assembly 2. The shell 1 is provided with a receiving cavity, and the prong assembly 2 is movably installed in the receiving cavity along a first direction. The prong assembly 2 includes a prong base 21, a splayed prong 22 and a parallel prong 23. The splayed prong 22 is arranged at one end of the prong base 21 along the first direction, and the parallel prong 23 is arranged at the other end of the prong base 21 along the first direction. The splayed prong 22 and the parallel prong 23 are not communicated with each other and are respectively used for connecting with different types of sockets. Specifically, the splayed prong 22 is suitable for being inserted into the inverted splayed hole of a common three-hole socket, and the parallel prong 23 is suitable for being inserted into a common two-hole socket. The prong assembly 2 of the embodiment has a first position and a second position. When the prong assembly 2 moves to the first position along the first direction, the splayed prong 22 extends out of the shell 1, and at this time, the splayed prong 22 can be inserted into the three-hole socket to realize the charging function of the charger. When the prong assembly 2 moves to the second position along the first direction, the parallel prong 23 extends out of the shell 1, and at this time, the parallel prong 23 can be inserted into the two-hole socket to realize the charging function of the charger. The double-prong charger of the embodiment extends different prongs according to different application scenarios. When the two-hole socket is available, the parallel prong 23 is extended; when the two-hole socket is used and the three-hole socket is idle, the splayed prong 22 is extended. In this way, the double-prong 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.

[0052] Further, when the splayed prong 22 extends out of the shell 1, the parallel prong 23 can be retracted into the shell 1; when the parallel prong 23 extends out of the shell 1, the splayed prong 22 can be retracted into the shell 1. In this way, the prong not used in the charging process can be prevented from being exposed outside the charger, so that the splayed prong 22 and the parallel prong 23 can be connected with the socket only by selection, and the safety and reliability of the charger are improved. Moreover, the above arrangement also makes the appearance of the charger more neat, and facilitates storage and carrying. Specifically, one end of the shell 1 close to the splayed prong 22 is provided with a splayed prong hole 101. When the splayed prong 22 needs to be used, it can extend out of the splayed prong hole 101, and when the splayed prong 22 does not need to be used, it can be retracted into the inside of the splayed prong hole 101. At the same time, one end of the shell 1 close to the parallel prong 23 is provided with a parallel prong hole 102, so as to facilitate the parallel prong 23 to extend out of or retract into the parallel prong hole 102. In this way, the use convenience and safety of the charger are effectively improved, the prong can be retracted into the prong hole when not in use, so as to avoid being damaged by being exposed outside, and the space occupied is reduced, facilitating carrying.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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, only the second push piece 122 is pressed to make the second elastic member 212 disengage from the limitation of the second limiting slot 112, so that the plug assembly 2 can be moved to the first position in the first direction, 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, only the first push piece 121 is pressed to make the first elastic member 211 disengage from the limitation of the first limiting slot 111, so that the plug assembly 2 can be moved to the second position in the first direction.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] In this embodiment, to facilitate the installation of the insert assembly 2 and the circuit board 4 within the housing 1, the housing 1 is open at one end near the figure-eight insert 22. The insert assembly 2 and the circuit board 4 are slidably installed within the housing 1 along a first direction. Optionally, the inner wall of the housing 1 is provided with a first slide rail 131 extending along the first direction, and the insert base 21 is provided with a slider 215. The slider 215 is slidably connected to the first slide rail 131, thus achieving the guiding and limiting function of the insert assembly 2, allowing the insert assembly 2 to be installed more accurately and smoothly in the housing 1, improving assembly efficiency, and facilitating the disassembly and maintenance of the insert assembly 2; moreover, the first slide rail 131 effectively improves the stability of the insert assembly 2's movement along the first direction. Preferably, the slider 215 is a slider extending along the first direction, so as to better slide and cooperate with the first slide rail 131. Of course, in other embodiments, a slider 215 can be provided on the inner wall of the housing 1, and a first slide rail 131 can be provided on the insert base 21, which can also achieve a sliding connection between the insert base 21 and the housing 1. Optionally, the inner wall of the housing 1 is also provided with a second slide rail 132 extending along the first direction, and the circuit board 4 is slidably connected to the second slide rail 132. This achieves the guiding and limiting function of the circuit board 4, so that the circuit board 4 can be installed in the housing 1 more accurately and smoothly, improving assembly efficiency and facilitating the disassembly and maintenance of the circuit board 4.

[0063] In this embodiment, to facilitate fixing the conductive spring 3 inside the housing 1, a support plate 14 is also provided inside the housing 1, and the conductive spring 3 is fixed on the support plate 14. Here, the support plate 14 can be fixedly connected to the housing 1, or integrally manufactured with the housing 1, or detachably installed inside the housing 1. Preferably, in this embodiment, the inner wall of the housing 1 is provided with a third slide rail extending along the first direction, and the support plate 14 is slidably installed inside the housing 1 via the third slide rail. This arrangement facilitates the separate manufacturing of the support plate 14, reduces manufacturing difficulty, and also facilitates the disassembly and maintenance of the conductive spring 3.

[0064] Furthermore, the housing 1 in this embodiment also includes a rear cover 15, which is detachably installed at one end of the housing 1 near the figure-eight insert 22. Installing the rear cover 15 facilitates the fixing of the insert assembly 2, circuit board 4, and support plate 14 within the housing 1.

Exemplarily, the rear cover 15 has several buckles 151 on its periphery, and the housing 1 has several slots 16 at its end. Each buckle 151 engages with its corresponding slot 16, thereby fixing the rear cover 15 to the housing 1. This configuration is simple in structure, easy to install, and reliable in connection. It should be noted that in other embodiments, a front cover can also be provided at one end of the housing 1 near the parallel insert 23. The front cover is detachably connected to the housing 1, and the front cover is provided with the aforementioned parallel insertion hole 102 for the parallel insert 23 to pass through.

[0065] Optionally, the charger in this embodiment also includes a shielding member 5. The shielding member 5 is detachably disposed at one end of the housing 1 near the figure-eight plug 22. When the figure-eight plug 22 is retracted into the housing 1, the shielding member 5 can be assembled onto the housing 1 and shield the outside of the figure-eight plug 22. Since the figure-eight plug 22 is not frequently used, this embodiment covers and shields the figure-eight plug 22 by means of the shielding member 5 when it is not in use, making the charger look cleaner and more aesthetically pleasing. Specifically, the back cover 15 of this embodiment is provided with a mounting cavity 152 that matches the shape of the shielding member 5. The aforementioned figure-eight plug hole 101 is disposed at the bottom of the mounting cavity 152. The side wall of the mounting cavity 152 is provided with a snap-fit ​​groove 153. The shielding member 5 is housed in the mounting cavity 152. The outer periphery of the shielding member 5 is provided with a snap-fit ​​protrusion 51, which snaps into the snap-fit ​​groove 153, thereby fixing the shielding member 5. Preferably, in this embodiment, the shielding member 5 is a silicone cap.

[0066] Example 2

[0067] This embodiment provides another dual-plug charger, which differs from Embodiment 1 in that the parallel plugs and figure-eight plugs in this embodiment are set independently and do not interact with each other. The specific structural arrangements of the housing, circuit board, support plate, conductive spring, back cover, shield, slide rails, elastic elements, limiting grooves, and levers can be referred to the structure in Embodiment 1, and will not be repeated here.

[0068] The dual-plug charger provided in this embodiment includes: a housing, a parallel plug assembly disposed at one end of the housing, and a figure-eight plug assembly disposed at the other end of the housing. The figure-eight plug assembly is movably disposed in the housing along a first direction, while the parallel plug assembly can be fixed to the housing or also movably disposed in the housing along the first direction. The parallel plug assembly includes a first base disposed within the housing and parallel plugs fixed to the first base; the figure-eight plug assembly includes a second base movably disposed within the housing along the first direction and figure-eight plugs fixed to the second base.

[0069] In this embodiment, the figure-eight insert assembly has a first position and a second position. When in the first position, the figure-eight insert extends out of the housing, and can be used to connect with the inverted figure-eight hole of the three-hole socket to realize the charging function of the charger. When in the second position, the figure-eight insert retracts into the housing, so that the figure-eight insert can be hidden inside the charger when not in use, avoiding bending damage caused by exposure, while reducing the space occupied, making the appearance of the charger neater, and making it easier to store and carry.

[0070] Furthermore, a conductive spring is provided inside the housing, and the conductive spring has a first conductive terminal; a third conductive terminal is provided on the second base, and the third conductive terminal is electrically connected to the figure-eight plug. When the figure-eight plug assembly moves to the first position, the first conductive terminal and the third conductive terminal make electrical contact, thus realizing electrical conduction between the figure-eight plug and the conductive spring, facilitating charging by inserting the figure-eight plug into a three-hole socket; when the figure-eight plug assembly moves to the second position, the first conductive terminal and the third conductive terminal are disconnected, and the figure-eight plug cannot be charged.

[0071] To fix the position of the figure-eight insert assembly, in this embodiment, the inner wall of the housing is provided with a first limiting groove and a second limiting groove, and the second base is provided with a first elastic member and a second elastic member. The first elastic member is used to engage with the first limiting groove to restrict the figure-eight insert assembly to a first position; the second elastic member is used to engage with the second limiting groove to restrict the figure-eight insert assembly to a second position. Simultaneously, the side wall of the housing is provided with a first lever opposite to the first limiting groove and a second lever opposite to the second limiting groove. When pressed, the first lever can move along the inner and outer sides of the housing, thereby pushing the first elastic member out of the first limiting groove and unlocking the figure-eight insert assembly to the first position; when pressed, the second lever can move along the inner and outer sides of the housing, thereby pushing the second elastic member out of the second limiting groove and unlocking the figure-eight insert assembly to the second position.

[0072] Normally, the figure-eight connector assembly is in the second position, with the connector retracted into the housing and the second elastic element engaged in the second limiting groove. This prevents the figure-eight connector assembly from moving within the housing, ensuring the charger's clean appearance. When the figure-eight connector needs to be used, simply press the second lever to disengage the second elastic element from the second limiting groove, allowing the figure-eight connector assembly to move along the first direction to the first position. In this position, the figure-eight connector extends out of the housing, and the first elastic element engages in the first limiting groove, locking the connector assembly in the first position and preventing further movement within the housing. This ensures reliable insertion between the figure-eight connector and the three-hole socket. When the figure-eight connector needs to be retracted again, simply press the first lever to disengage the first elastic element from the first limiting groove, allowing the figure-eight connector assembly to move along the first direction to the second position.

[0073] Furthermore, a first elastic reset member is provided between the figure-eight insert assembly and the housing, the first elastic reset member having a tendency to extend the figure-eight insert out of the housing. This design allows the figure-eight insert assembly to automatically pop out of the housing using the elastic force of the first elastic reset member after being unlocked in the second position, without requiring manual ejection, making it more convenient to use and improving the user experience. Optionally, the first elastic reset member is a compression spring, which has a simple structure and reliable ejection.

[0074] Preferably, in this embodiment, the parallel insert assembly is movably disposed within the housing along the first direction. The parallel insert assembly has a third position and a fourth position. When it is in the third position, the parallel insert extends out of the housing, and can be used to connect with the two-hole socket to realize the charging function of the charger. When it is in the fourth position, the parallel insert retracts into the housing, so that the parallel insert can be hidden inside the charger when not in use, avoiding bending damage caused by exposure, while saving space and making it convenient to carry.

[0075] Furthermore, the conductive spring is provided with a second conductive terminal; the first base is provided with a fourth conductive terminal, which is electrically connected to the parallel insert. When the parallel insert assembly moves to the third position, the second conductive terminal and the fourth conductive terminal make electrical contact, thus realizing electrical conduction between the parallel insert and the conductive spring, facilitating charging by inserting the parallel insert into the two-hole socket; when the parallel insert assembly moves to the fourth position, the second conductive terminal and the fourth conductive terminal are disconnected, and the parallel insert cannot be charged.

[0076] Similarly, to fix the position of the parallel insert assembly, in this embodiment, the inner wall of the housing is provided with a fourth limiting groove and a fifth limiting groove, and the first base is provided with a third elastic member and a fourth elastic member. The third elastic member is used to engage with the fourth limiting groove to restrict the parallel insert assembly to a third position; the fourth elastic member is used to engage with the fifth limiting groove to restrict the parallel insert assembly to a fourth position. Simultaneously, the side wall of the housing is provided with a third lever opposite to the fourth limiting groove and a fourth lever opposite to the fifth limiting groove. When pressed, the third lever can move along the inner and outer sides of the housing, thereby pushing the third elastic member out of the fourth limiting groove and unlocking the parallel insert assembly in the third position; when pressed, the fourth lever can move along the inner and outer sides of the housing, thereby pushing the fourth elastic member out of the fifth limiting groove and unlocking the parallel insert assembly in the fourth position.

[0077] Furthermore, a second elastic reset member is provided between the parallel insert assembly and the housing, the second elastic reset member having a tendency to extend the parallel insert out of the housing. This arrangement allows the parallel insert assembly to automatically pop out of the housing using the elastic force of the second elastic reset member after being unlocked in the fourth position, without requiring manual ejection, making it more convenient to use and improving the user experience. Optionally, the second elastic reset member is a compression spring, which has a simple structure and reliable ejection.

[0078] The charger provided in this embodiment is compatible with both two-prong and three-prong plugs by setting up a figure-eight plug assembly and a parallel plug assembly. Both the figure-eight plug and the parallel plug can retract into the housing. When needed, they automatically pop out due to the action of the elastic reset member, and when not needed, they can retract into the housing for easy storage and carrying.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
