Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to a charger. Background Technology

[0002] With the increasing number of electronic products, more and more appliances require charging in our daily lives, such as Bluetooth headsets, mobile phones, and handheld fans. When people are out and about, especially in public places like airports and train stations, public power outlets become scarce due to high traffic. Ordinary chargers are only compatible with two-prong outlets, not three-prong ones. Taking the most common five-hole socket as an example, when the two-prong outlets are in use, many three-prong outlets remain unused, causing inconvenience. Furthermore, existing multi-plug chargers have multiple exposed plugs, which are unsightly, inconvenient to carry, and pose safety hazards when only one plug is being used for charging.

[0003] Therefore, there is an urgent need for a charger to solve the above-mentioned technical problems. Utility Model Content

[0004] Based on the above, the purpose of this utility model is to provide a charger that is compatible with both two-prong and three-prong plugs, has a simple structure, is easy to operate, is safe and reliable, and has a neat and beautiful appearance, making it easy to store and carry.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A charger, comprising:

[0007] case;

[0008] An insert assembly is movably disposed within the housing along a first direction. The insert assembly includes an insert base, a figure-eight insert at one end of the insert base, and a parallel insert at the other end of the insert base. The insert assembly has a first position and a second position. In the first position, the figure-eight insert extends out of the housing, and the parallel insert retracts into the housing. In the second position, the parallel insert extends out of the housing, and the figure-eight insert retracts into the housing.

[0009] A shielding component is detachably disposed at one end of the housing near the figure-eight insert. When the figure-eight insert is retracted into the housing, the shielding component can be installed and shield the outside of the figure-eight insert.

[0010] In some possible implementations, the housing is provided with a rear cover, which is detachably mounted on one end of the housing near the figure-eight insert; the rear cover is provided with a mounting cavity, and the shielding member is detachably disposed in the mounting cavity.

[0011] In some possible implementations, the bottom of the mounting cavity is provided with a figure-eight insertion hole for the figure-eight insert to pass through; the end of the housing near the parallel insert is provided with a parallel insertion hole for the parallel insert to pass through.

[0012] In some possible implementations, the shielding element is a silicone cap that snaps into the mounting cavity.

[0013] In some possible implementations, the inner wall of the housing is provided with a first limiting groove and a second limiting groove in sequence along a first direction, and the side wall of the housing is provided with a first lever opposite to the position of the first limiting groove and a second lever opposite to the position of the second limiting groove. The first lever and the second lever can move along the inner and outer sides of the housing after being pressed; the insert assembly is provided with a first elastic element and a second elastic element in sequence along a first direction.

[0014] When the insert assembly is in the first position, the first elastic element is engaged in the first limiting groove, and the first elastic element can be disengaged from the first limiting groove by pressing the first lever; when the insert assembly is in the second position, the second elastic element is engaged in the second limiting groove, and the second elastic element can be disengaged from the second limiting groove by pressing the second lever.

[0015] In some possible implementations, both the first and second paddles include a fixed portion and a movable portion. The fixed portion is fixedly connected to the side wall of the housing, and the outer periphery of the movable portion is spaced apart from the side wall of the housing to allow it to move inside and outside the housing.

[0016] In some possible implementations, the inner wall of the housing is further provided with a third limiting groove, which is located between the first limiting groove and the second limiting groove; when the insert assembly is in the first position, the first elastic member is located in the first limiting groove and the second elastic member is located in the third limiting groove; when the insert assembly is in the second position, the second elastic member is located in the second limiting groove and the first elastic member is located in the third limiting groove.

[0017] In some possible implementations, both the first elastic element and the second elastic element are limiting springs. One end of the limiting spring along the first direction is fixedly connected to the insert base, and the other end along the first direction is suspended relative to the surface of the insert base. The suspended end can bend towards the surface of the insert base after being compressed. The suspended ends of the first elastic element and the suspended ends of the second elastic element are arranged facing each other.

[0018] In some possible implementations, the housing contains a conductive spring with a first conductive terminal and a second conductive terminal; the insert base has a third conductive terminal and a fourth conductive terminal, the third conductive terminal being electrically connected to the figure-eight insert, and the fourth conductive terminal being electrically connected to the parallel insert; when the insert assembly is in a first position, the first conductive terminal is in electrical contact with the third conductive terminal; when the insert assembly is in a second position, the second conductive terminal is in electrical contact with the fourth conductive terminal.

[0019] In some possible implementations, a circuit board is disposed within the housing, and a fifth conductive terminal is disposed on the circuit board. The circuit board is electrically connected to the conductive spring through the fifth conductive terminal. When the insert assembly is in the first position, the figure-eight insert is electrically connected to the circuit board. When the insert assembly is in the second position, the parallel insert is electrically connected to the circuit board.

[0020] The beneficial effects of this utility model are:

[0021] The charger provided by this utility model allows the figure-eight connector to extend out of the housing when the connector assembly moves to a first position along a first direction. At this time, the figure-eight connector can be inserted into a three-hole socket for charging. When the connector assembly moves to a second position along the first direction, the parallel connector extends out of the housing. At this time, the parallel connector can be inserted into a two-hole socket for charging. Furthermore, when the figure-eight connector extends out of the housing, the parallel connector can retract into the housing, and vice versa. This prevents unused connectors from being exposed outside the charger during charging, ensuring that only one of the figure-eight or parallel connectors can be connected to the socket, thus improving the charger's safety and reliability. In addition, since the figure-eight connector is not frequently used, this utility model covers and conceals it when not in use, making the charger's appearance neater, more aesthetically pleasing, and easier to store and carry.

[0022] The charger extends different prongs depending on the application scenario. When the two-prong plug is available, a parallel prong extends; when the two-prong plug is in use and the three-prong plug is idle, a figure-eight prong extends. This makes the charger suitable for both two-prong and three-prong plugs. It has a simple structure, is easy to operate, safe and reliable, and has a neat appearance and is easy to store.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this utility model, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0047] This utility model provides a charger for charging electronic products such as mobile phones, tablets, Bluetooth headsets, and handheld fans. It solves the problems of existing chargers that can only be used with two-prong plugs and not with three-prong plugs, as well as the problems of existing multi-plug chargers where multiple plugs are exposed, resulting in an untidy appearance, inconvenience in carrying, and safety hazards during use.

[0048] like Figures 1 to 14 As shown, the charger provided in this embodiment includes a housing 1 and a plug assembly 2. The housing 1 has a receiving cavity, and the plug assembly 2 is movably installed within the receiving cavity along a first direction. The plug assembly 2 includes a plug base 21, a figure-eight plug 22, and a parallel plug 23. The figure-eight plug 22 is disposed at one end of the plug base 21 along the first direction, and the parallel plug 23 is disposed at the other end of the plug base 21 along the first direction. The figure-eight plug 22 and the parallel plug 23 are not interconnected and are used to connect to different types of sockets. Specifically, the figure-eight plug 22 is suitable for the inverted figure-eight holes of a standard three-hole socket, and the parallel plug 23 is suitable for a standard two-hole socket. In this embodiment, the insert assembly 2 has a first position and a second position. When the insert assembly 2 moves to the first position along the first direction, the figure-eight insert 22 extends out of the housing 1, and can be inserted into the three-hole socket to realize the charging function of the charger. When the insert assembly 2 moves to the second position along the first direction, the parallel insert 23 extends out of the housing 1, and can be inserted into the two-hole socket to realize the charging function of the charger. The charger in this embodiment extends different inserts according to different application scenarios. When the two-hole socket is available, the parallel insert 23 extends; when the two-hole socket is used and the three-hole socket is idle, the figure-eight insert 22 extends. This allows the charger to be used with both two-hole and three-hole sockets, and it has a simple structure, is easy to operate, and is reliable. In this embodiment, the first direction specifically refers to the front-rear direction of the housing 1.

[0049] Furthermore, when the figure-eight connector 22 extends outside the housing 1, the parallel connector 23 can retract inside the housing 1; when the parallel connector 23 extends outside the housing 1, the figure-eight connector 22 can retract inside the housing 1. This design prevents unused connectors from being exposed outside the charger during charging, ensuring that only one of the figure-eight connector 22 and the parallel connector 23 can be connected to the socket, thus improving the safety and reliability of the charger. Moreover, this design also makes the charger look neater, making it easier to store and carry.

[0050] The charger in this embodiment also includes a shielding member 5, which is detachably disposed at one end of the housing 1 near the figure-eight connector 22. When the figure-eight connector 22 is retracted into the housing 1, the shielding member 5 can be mounted on the housing 1 and shield the outside of the figure-eight connector 22. Since the figure-eight connector 22 is not frequently used, this embodiment covers and shields the figure-eight connector 22 by means of the shielding member 5 when the figure-eight connector 22 is not in use, making the charger look cleaner and more aesthetically pleasing.

[0051] Furthermore, the end of the housing 1 near the figure-eight insert 22 is provided with a figure-eight socket 101. When the figure-eight insert 22 is needed, it can extend out of the figure-eight socket 101, and when it is not needed, it can retract into the figure-eight socket 101. At the same time, the end of the housing 1 near the parallel insert 23 is provided with a parallel socket 102, so that the parallel insert 23 can extend out or retract into the parallel socket 102. This effectively improves the convenience and safety of the charger, allowing the corresponding inserts to retract into the socket when not in use, avoiding bending damage from being exposed, while also reducing space occupation and making it convenient to carry.

[0052] In this embodiment, a conductive spring 3 is also provided inside the housing 1. The conductive spring 3 is provided with two first conductive terminals 31 and two second conductive terminals 32. The insert base 21 is provided with two third conductive terminals 213 and two fourth conductive terminals 214. Each third conductive terminal 213 is electrically connected to the figure-eight insert 22, and each fourth conductive terminal 214 is electrically connected to the parallel insert 23. When the insert assembly 2 moves to the first position, the two first conductive terminals 31 and the two third conductive terminals 213 make one-to-one electrical contact, thus realizing electrical conduction between the figure-eight insert 22 and the conductive spring 3, facilitating charging by inserting the figure-eight insert 22 into a three-hole socket. When the insert assembly 2 moves to the second position, the two second conductive terminals 32 and the two fourth conductive terminals 214 make one-to-one electrical contact, thus realizing electrical conduction between the parallel insert 23 and the conductive spring 3, facilitating charging by inserting the parallel insert 23 into a two-hole socket. Optionally, the two first conductive terminals 31, the two second conductive terminals 32, the two third conductive terminals 213, and the two fourth conductive terminals 214 are arranged sequentially along the second direction. In this embodiment, the second direction is perpendicular to the first direction, specifically the width direction of the housing 1.

[0053] Furthermore, a circuit board 4 is also provided inside the housing 1. The circuit board 4 has two fifth conductive terminals 45, which are electrically connected to the conductive spring 3. This allows the figure-eight connector 22 to be electrically connected to the circuit board 4 when the connector assembly 2 is in the first position, and the parallel connector 23 to be electrically connected to the circuit board 4 when the connector assembly 2 is in the second position. Specifically, the circuit board 4 is provided with a transformer element 41, a voltage regulator element 42, a fuse 43, and a USB interface 44. The current on the figure-eight connector 22 or the parallel connector 23 flows to the circuit board 4 through the conductive spring 3, and then flows sequentially through the transformer element 41, the voltage regulator element 42, and the fuse 43 to the USB interface 44, thus achieving electrical connection between the figure-eight connector 22 or the parallel connector 23 and the USB interface 44. In addition, the housing 1 is also provided with a USB interface reserved hole 17 to facilitate the insertion of the USB cable, the other end of which is connected to the electronic product.

[0054] To fix the position of the insert assembly 2, in this embodiment, the inner wall of the housing 1 is provided with a first limiting groove 111 and a second limiting groove 112, and the insert base 21 is provided with a first elastic member 211 and a second elastic member 212. The first elastic member 211 is used to engage with the first limiting groove 111 to restrict the insert assembly 2 to a first position; the second elastic member 212 is used to engage with the second limiting groove 112 to restrict the insert assembly 2 to a second position. Meanwhile, the side wall of the housing 1 is also provided with a first lever 121 opposite to the first limiting groove 111 and a second lever 122 opposite to the second limiting groove 112. The first lever 121 can move along the inner and outer sides of the housing 1 after being pressed, thereby pushing the first elastic member 211 out of the first limiting groove 111 and unlocking the insert assembly 2 in the first position. The second lever 122 can move along the inner and outer sides of the housing 1 after being pressed, thereby pushing the second elastic member 212 out of the second limiting groove 112 and unlocking the insert assembly 2 in the second position.

[0055] Specifically, the working process of this embodiment is as follows: Since the parallel insert 23 is used frequently, under normal circumstances, the insert assembly 2 is located in the second position. At this time, the parallel insert 23 extends out of the housing 1, and the second elastic member 212 is engaged in the second limiting groove 112, so that the insert assembly 2 is locked in the second position and cannot continue to move in the housing 1. This ensures the reliability of the insertion of the parallel insert 23 and the two-hole socket during charging. When the figure-eight insert 22 needs to be used, simply press the second lever 122 to disengage the second elastic member 212 from the restriction of the second limiting groove 112, and the insert assembly 2 can be pushed to move in the first direction to the first position. At this time, the figure-eight insert 22 extends out of the housing 1, and the first elastic member 211 is engaged in the first limiting groove 111, so that the insert assembly 2 is locked in the first position and cannot continue to move in the housing 1. This ensures the reliability of the insertion of the figure-eight insert 22 and the three-hole socket. When the parallel insert 23 is needed again, simply press the first lever 121 to disengage the first elastic member 211 from the first limiting groove 111, and the insert assembly 2 can be pushed to move to the second position along the first direction.

[0056] Furthermore, both the first limiting groove 111 and the second limiting groove 112 penetrate the side wall of the housing 1. The first lever 121 is located on the side of the first limiting groove 111 near the outer wall of the housing 1, and the second lever 122 is located on the side of the second limiting groove 112 near the outer wall of the housing 1. Optionally, the first lever 121 and the second lever 122 have the same structure, both including a fixed part and a movable part. The fixed part is fixedly connected to the side wall of the housing 1, and the outer periphery of the movable part is spaced from the side wall of the housing 1, so that the movable part can move to a certain extent inside and outside the housing 1. By pressing the movable part inward, the insert assembly 2 can be unlocked. In this embodiment, the first lever 121 and the second lever 122 are preferably integrally formed with the housing 1, which has a simple structure, is easy to process, and is reliable in use.

[0057] In this embodiment, when the first elastic element 211 is engaged with the first limiting groove 111, the second elastic element 212 is compressed and abuts against the surface of the insert base 21; when the second elastic element 212 is engaged with the second limiting groove 112, the first elastic element 211 is compressed and abuts against the surface of the insert base 21. To reduce the impact on the service life of the first elastic element 211 and the second elastic element 212 due to prolonged compression, a third limiting groove 113 is also provided in this embodiment. Specifically, the first limiting groove 111 and the second limiting groove 112 are sequentially arranged on the side wall of the housing 1 along the first direction, and the third limiting groove 113 is located between the first limiting groove 111 and the second limiting groove 112; simultaneously, the first elastic element 211 and the second elastic element 212 are also sequentially arranged on the insert base 21 along the first direction. When the insert assembly 2 is in the first position, the first elastic element 211 is located in the first limiting groove 111, and the second elastic element 212 is located in the third limiting groove 113. This provides a certain amount of accommodating space for the second elastic element 212, preventing it from being damaged by long-term compression and affecting its resilience. When the insert assembly 2 is in the second position, the second elastic element 212 is located in the second limiting groove 112, and the first elastic element 211 is located in the third limiting groove 113. This provides a certain amount of accommodating space for the first elastic element 211, preventing it from being damaged by long-term compression and affecting its resilience. Of course, in order to facilitate the smooth disengagement of the first elastic element 211 and the second elastic element 212 from the third limiting groove 113 when the insert assembly 2 moves, guide ramps can be provided at both ends of the third limiting groove 113, or corresponding guide structures can be provided on both the first elastic element 211 and the second elastic element 212, or the third limiting groove 113 can also penetrate the side wall of the housing 1, and corresponding paddle structures can also be provided on the outside of the third limiting groove 113, etc. This embodiment does not limit this.

[0058] Optionally, in this embodiment, the first elastic element 211 is a first limiting spring, and the second elastic element 212 is a second limiting spring. One end of the first limiting spring along the first direction is fixedly connected to the insert base 21, and the other end along the first direction is suspended relative to the surface of the insert base 21. When the insert assembly 2 slides in the housing 1, the suspended end of the first limiting spring is squeezed by the inner wall of the housing 1 and bends towards the surface of the insert base 21. When the first limiting spring enters the first limiting groove 111, the suspended end of the first limiting spring pops out and can abut against the groove wall of the first limiting groove 111. Similarly, one end of the second limiting spring is fixedly connected to the insert base 21 along the first direction, and the other end along the first direction is suspended relative to the surface of the insert base 21. When the insert assembly 2 slides inside the housing 1, the suspended end of the second limiting spring is squeezed by the inner wall of the housing 1 and bends towards the surface of the insert base 21. When the second limiting spring enters the second limiting groove 112, the suspended end of the second limiting spring pops outward and can abut against the groove wall of the second limiting groove 112. Specifically, in this embodiment, the suspended ends of the first and second limiting springs are close to each other, while the fixed ends of the first and second limiting springs are far apart.

[0059] Preferably, in this embodiment, the third limiting groove 113 is a blind groove (i.e., not penetrating the side wall of the housing 1) disposed on the inner wall of the housing 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 7 and Figure 8As shown, when the insert assembly 2 is inserted into the housing 1 from left to right along the first direction, the second limiting spring first enters the first limiting groove 111; then the second limiting spring continues to move forward into the third limiting groove 113. At this time, the first limiting spring enters the first limiting groove 111, and the suspended end of the first limiting spring abuts against the right side wall of the first limiting groove 111, thus preventing the insert assembly 2 from moving further to the right. At the same time, the suspended end of the second limiting spring abuts against the left side wall of the third limiting groove 113, preventing the insert assembly 2 from moving to the left. In this way, the insert assembly 2 is locked in the first position, ensuring that the figure-eight insert 22 will not move into the housing 1 during the process of being inserted into the three-hole socket. The first limiting spring is then disengaged from the first limiting groove 111 by pressing the first lever 121, and the insert assembly 2 is pushed to continue moving to the right until the second limiting spring enters the second limiting groove 112 and the first limiting spring enters the third limiting groove 113. At this time, the suspended end of the second limiting spring abuts against the left side wall of the second limiting groove 112, preventing the insert assembly 2 from moving to the left. At the same time, the suspended end of the first limiting spring abuts against the right side wall of the third limiting groove 113, preventing the insert assembly 2 from moving to the right. Thus, the insert assembly 2 is locked in the second position, ensuring that the parallel insert 23 will not retract into the housing 1 during the insertion process with the socket.

[0060] Of course, in other embodiments, the first elastic member 211 and the second elastic member 212 can also be other elastic limiting members, such as spring positioning pins. The positioning pins are pushed into the first limiting groove 111 or the second limiting groove 112 by the spring, which can also achieve the locking of the position of the insert assembly 2.

[0061] 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.

[0062] 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.
