Description

Technical Field

[0001] The present invention relates to the technical field of chargers, and in particular to a bidirectional charger head. Background Art

[0002] With the increase in electronic products, there are more and more electrical appliances that need to be charged by chargers in life, such as Bluetooth headsets, mobile phones, hand-held fans, etc. When people go out, especially in public places such as airports and stations, the public socket resources become scarce due to the large number of people. Ordinary charger heads can only be applied to two-hole sockets and cannot be applied to three-hole sockets. Taking the most commonly used five-hole socket panel as an example, when the two-hole socket is in use, the three-hole socket is largely idle and cannot be charged, which brings inconvenience to people. In addition, for the existing multi-plug charger heads, their internal device structures are complex, and the plugs are prone to movement during use, resulting in poor reliability.

[0003] Therefore, there is an urgent need for a bidirectional charger head to solve the above technical problems. Summary of the Invention

[0004] Based on the above, the object of the present invention is to provide a bidirectional charger head that can be applied to both two-hole sockets and three-hole sockets, and has a simple structure, convenient operation, and reliable use.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A bidirectional charger head includes:

[0007] A housing, the inner wall of the housing is provided with a first limiting groove and a second limiting groove, a conductive elastic sheet is arranged in the housing, and a first conductive terminal and a second conductive terminal are arranged on the conductive elastic sheet;

[0008] A blade assembly is movably arranged in the housing along a first direction. The blade assembly includes a blade base, an eight-shaped blade arranged at one end of the blade base, and a parallel blade arranged at the other end of the blade base; a first elastic member and a second elastic member are arranged on the blade base; a third conductive terminal and a fourth conductive terminal are also arranged on the blade base. The third conductive terminal is electrically connected to the eight-shaped blade, and the fourth conductive terminal is electrically connected to the parallel blade;

[0009] The blade assembly has a first position and a second position. When in the first position, the eight-shaped blade extends out of the housing, the first conductive terminal is in electrical contact with the third conductive terminal, and the first elastic member is clamped in the first limiting groove; when in the second position, the parallel blade extends out of the housing, the second conductive terminal is in electrical contact with the fourth conductive terminal, and the second elastic member is clamped in the second limiting groove.

[0010] In some possible embodiments, the side wall of the housing is provided with a first flap opposite to the position of the first limiting groove and a second flap opposite to the position of the second limiting groove. Both the first flap and the second flap can move along the inner and outer sides of the housing when pressed. When the first elastic member is clamped in the first limiting groove, pressing the first flap can make the first elastic member disengage from the first limiting groove. When the second elastic member is clamped in the second limiting groove, pressing the second flap can make the second elastic member disengage from the second limiting groove.

[0011] In some possible embodiments, both the first flap and the second flap include: a fixed portion and a movable portion. The fixed portion is fixedly connected to the side wall of the housing, and there is a spaced gap between the outer periphery of the movable portion and the side wall of the housing to move along the inner and outer sides of the housing.

[0012] In some possible embodiments, the inner wall of the housing is further provided with a third limiting groove. The first limiting groove, the third limiting groove, and the second limiting groove are arranged in sequence along a first direction. When the insert component is in a 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 component is in a 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.

[0013] In some possible embodiments, both the first elastic member and the second elastic member are limiting elastic pieces. One end of the limiting elastic piece 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. And the suspended end can bend towards the direction close to the surface of the insert base when pressed. The suspended ends of the first elastic member and the second elastic member are arranged facing each other.

[0014] In some possible embodiments, among the inner wall of the housing and the insert base, one of them is provided with a first slide rail extending along the first direction, and the other is provided with a slider. The slider is slidably connected to the first slide rail.

[0015] In some possible embodiments, a circuit board is arranged in the housing. A fifth conductive terminal is arranged on the circuit board. The circuit board is electrically connected to the conductive elastic piece through the fifth conductive terminal. When the insert component is in the first position, the eight-shaped insert is electrically connected to the circuit board. When the insert component is in the second position, the parallel insert is electrically connected to the circuit board.

[0016] In some possible embodiments, a voltage transformation element, a voltage stabilizing element, a fuse, and a USB interface are provided on the circuit board, and a USB interface reserved hole is provided on the housing for inserting a USB cable.

[0017] In some possible embodiments, a second sliding rail extending in a first direction is provided on the inner wall of the housing, and the circuit board is slidably mounted in the housing through the second sliding rail.

[0018] In some possible embodiments, a support plate is provided in the housing, and the conductive elastic sheet is fixed on the support plate.

[0019] Advantages of the present invention:

[0020] For the bidirectional charger provided by the present invention, when the insert component moves to the first position along the first direction, the octagonal inserts extend out of the housing. At this time, the first conductive terminal is in electrical contact with the third conductive terminal, thus realizing electrical conduction between the octagonal inserts and the conductive elastic sheet, facilitating charging by inserting the octagonal inserts into a three-hole socket. Moreover, at this time, the first elastic member is clamped in the first limiting groove, so that the insert component is fixed and cannot move further in the housing, ensuring the insertion reliability between the octagonal inserts and the three-hole socket. When the parallel inserts need to be used, only by pushing the first elastic member out of the restriction of the first limiting groove, the insert component can be pushed to move to the second position along the first direction. At this time, the parallel inserts extend out of the housing, and the second conductive terminal is in electrical contact with the fourth conductive terminal, thus realizing electrical conduction between the parallel inserts and the conductive elastic sheet, facilitating charging by inserting the parallel inserts into a two-hole socket. Moreover, at this time, the second elastic member is clamped in the second limiting groove, so that the insert component is fixed and cannot move further in the housing, ensuring the insertion reliability between the parallel inserts and the two-hole socket. When switching back to the octagonal inserts, only by pushing the second elastic member out of the restriction of the second limiting groove, the insert component can be pushed to move to the first position along the first direction.

[0021] This bidirectional charger extends different inserts according to different application scenarios. When the two-hole socket is available, the parallel inserts are extended. When the two-hole socket is in use and the three-hole socket is idle, the octagonal inserts are extended. In this way, the bidirectional charger can be applicable to both the two-hole socket and the three-hole socket, and has a simple structure, convenient operation, and reliable use.

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention rather than all structures are shown in the accompanying drawings.

[0043] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature not being in direct contact but being in contact through other features therebetween. Moreover, the first feature being "above", "above the top of", and "on the top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below the bottom of", and "under the bottom of" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0045] In the description of the present invention, the orientation or positional relationships such as "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings. These are only for convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] An embodiment of the present invention provides a bidirectional charger for charging electronic products such as mobile phones, tablets, Bluetooth headsets, and handheld fans, to solve the problems in the prior art that the charger can only be applicable to two-hole sockets, not three-hole sockets, and the internal device structure of the existing multi-plug chargers is complex, and the plugs are prone to movement during use, resulting in poor reliability.

[0047] As Figures 1 to 14 shown, the bidirectional charger provided in this embodiment includes a housing 1 and a blade assembly 2. A receiving cavity is provided inside the housing 1, and the blade assembly 2 is movably installed in the receiving cavity along a first direction. The blade assembly 2 includes a blade base 21, an inverted-V blade 22, and a parallel blade 23. The inverted-V blade 22 is provided at one end of the blade base 21 along the first direction, and the parallel blade 23 is provided at the other end of the blade base 21 along the first direction. And the inverted-V blade 22 and the parallel blade 23 are not connected to each other and are respectively used to connect to different types of sockets. Specifically, the inverted-V blade 22 is suitable for the inverted-V holes of ordinary three-hole sockets, and the parallel blade 23 is suitable for ordinary two-hole sockets. The blade assembly 2 of this embodiment has a first position and a second position. When the blade assembly 2 moves along the first direction to the first position, the inverted-V blade 22 extends out of the housing 1. At this time, the inverted-V blade 22 can be inserted into the three-hole socket to realize the charging function of the charger; when the blade assembly 2 moves along the first direction to the second position, the parallel blade 23 extends out of the housing 1. At this time, the parallel blade 23 can be inserted into the two-hole socket to realize the charging function of the charger. The bidirectional charger of this embodiment extends different blades according to different application scenarios. When the two-hole socket is available, the parallel blade 23 is extended. When the two-hole socket is in use and the three-hole socket is idle, the inverted-V blade 22 is extended. In this way, the bidirectional charger can be applicable to both two-hole sockets and three-hole sockets, and has a simple structure, convenient operation, and reliable use. In this embodiment, the first direction is specifically the front-back direction of the housing 1.

[0048] Further, when the octagonal insert piece 22 extends out of the housing 1, the parallel insert piece 23 can retract into the interior of the housing 1; when the parallel insert piece 23 extends out of the housing 1, the octagonal insert piece 22 can retract into the interior of the housing 1. With such an arrangement, it is possible to prevent the unused insert pieces from being exposed outside the charger during the charging process, enabling only one of the octagonal insert piece 22 and the parallel insert piece 23 to be connected to the socket, thereby improving the safety and reliability of the charger; moreover, the above arrangement also makes the appearance of the charger neater, facilitating storage and carrying. Specifically, an octagonal jack 101 is provided at one end of the housing 1 close to the octagonal insert piece 22. When the octagonal insert piece 22 is needed, it can extend out from the octagonal jack 101, and when the octagonal insert piece 22 is not needed, it can retract inside the octagonal jack 101; at the same time, a parallel jack 102 is provided at one end of the housing 1 close to the parallel insert piece 23 to facilitate the parallel insert piece 23 to extend out from it or retract inside the parallel jack 102. This effectively improves the convenience and safety of using the charger, enabling the corresponding insert pieces to retract into the jacks when not in use, avoiding bending damage caused by being exposed, and at the same time reducing the occupied space and facilitating carrying.

[0049] In this embodiment, a conductive elastic sheet 3 is further provided inside the housing 1. Two first conductive terminals 31 and two second conductive terminals 32 are provided on the conductive elastic sheet 3. Two third conductive terminals 213 and two fourth conductive terminals 214 are provided on the insert base 21. Each of the third conductive terminals 213 is electrically connected to the octagonal insert piece 22, and each of the fourth conductive terminals 214 is electrically connected to the parallel insert piece 23. When the insert assembly 2 moves to the first position, the two first conductive terminals 31 are in one-to-one electrical contact with the two third conductive terminals 213, thus realizing the electrical conduction between the octagonal insert piece 22 and the conductive elastic sheet 3, facilitating charging by plugging the octagonal insert piece 22 into a three-hole socket; when the insert assembly 2 moves to the second position, the two second conductive terminals 32 are in one-to-one electrical contact with the two fourth conductive terminals 214, thus realizing the electrical conduction between the parallel insert piece 23 and the conductive elastic sheet 3, facilitating charging by plugging the parallel insert piece 23 into a two-hole socket. Optionally, the two first conductive terminals 31 are arranged in sequence along the second direction, the two second conductive terminals 32 are arranged in sequence along the second direction, the two third conductive terminals 213 are arranged in sequence along the second direction, and the two fourth conductive terminals 214 are arranged in sequence along the second direction. In this embodiment, the second direction is perpendicular to the first direction and is specifically the width direction of the housing 1.

[0050] Further, a circuit board 4 is also disposed inside the housing 1. Two fifth conductive terminals 45 are provided on the circuit board 4. The circuit board 4 is electrically connected to the conductive elastic sheet 3 through the two fifth conductive terminals 45. Thus, when the insert component 2 is in the first position, the eight-shaped insert 22 is electrically connected to the circuit board 4. When the insert component 2 is in the second position, the parallel insert 23 is electrically connected to the circuit board 4. Specifically, a voltage transformation element 41, a voltage stabilizing element 42, a fuse 43, a USB interface 44, etc. are provided on the circuit board 4. The current on the eight-shaped insert 22 or the parallel insert 23 flows to the circuit board 4 through the conductive elastic sheet 3, and then sequentially flows through the voltage transformation element 41, the voltage stabilizing element 42, and the fuse 43 to the USB interface 44, thus realizing the electrical connection between the eight-shaped insert 22 or the parallel insert 23 and the USB interface 44. In addition, a USB interface reserved hole 17 is also provided on the housing 1 to facilitate the insertion of a USB cable. The other end of the USB cable is connected to an electronic product.

[0051] To fix the position of the insert component 2, in this embodiment, a first limiting groove 111 and a second limiting groove 112 are provided on the inner wall of the housing 1. A first elastic member 211 and a second elastic member 212 are provided on the insert base 21. The first elastic member 211 is used for snap-fitting with the first limiting groove 111 to limit the insert component 2 to the first position. The second elastic member 212 is used for snap-fitting with the second limiting groove 112 to limit the insert component 2 to the second position. At the same time, a first dial 121 opposite to the first limiting groove 111 and a second dial 122 opposite to the second limiting groove 112 are provided on the side wall of the housing 1. The first dial 121 can move along the inner and outer sides of the housing 1 after being pressed, so as to push the first elastic member 211 out of the first limiting groove 111 and realize the unlocking of the insert component 2 in the first position. The second dial 122 can move along the inner and outer sides of the housing 1 after being pressed, so as to push the second elastic member 212 out of the second limiting groove 112 and realize the unlocking of the insert component 2 in the second position.

[0052] Specifically, the working process of this embodiment is as follows: Since the parallel plug 23 is used frequently, usually, the plug assembly 2 is located in the second position, at which time the parallel plug 23 extends out of the housing 1, and the second elastic member 212 is engaged in the second limiting groove 112, so that the plug assembly 2 is locked in the second position and cannot continue to move in the housing 1, thus ensuring the plug-in reliability of the parallel plug 23 and the two-hole socket during the charging process. When the eight-shaped plug 22 is needed, it is only necessary to press the second paddle 122 to make the second elastic member 212 disengage from the restriction of the second limiting groove 112, and then the plug assembly 2 can be pushed to move to the first position along the first direction, at which time the eight-shaped plug 22 extends out of the housing 1, and the first elastic member 211 is engaged in the first limiting groove 111, so that the plug assembly 2 is locked in the first position and cannot continue to move in the housing 1, thus ensuring the plug-in reliability of the eight-shaped plug 22 and the three-hole socket. When the parallel inserting piece 23 is needed again, the first paddle 121 is pressed to release the first elastic member 211 from the restriction of the first limiting groove 111 , so that the inserting piece assembly 2 can be pushed to move to the second position along the first direction.

[0053] Furthermore, the first limiting groove 111 and the second limiting groove 112 are both set through the side wall of the shell 1, the first paddle 121 is located on the side of the first limiting groove 111 close to the outer wall of the shell 1, and the second paddle 122 is located on the side of the second limiting groove 112 close to the outer wall of the shell 1. Optionally, the first paddle 121 and the second paddle 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 shell 1, and the outer periphery of the movable part and the side wall of the shell 1 have a hollow space, so that the movable part can move to a certain extent inside and outside the shell 1, and the plug assembly 2 can be unlocked by pressing the movable part inward. In this embodiment, the first paddle 121 and the second paddle 122 are preferably integrally formed with the shell 1, with a simple structure, easy processing, and reliable use.

[0054] In this embodiment, when the first elastic member 211 is engaged with the first limiting groove 111, the second elastic member 212 is compressed and abuts against the surface of the insert base 21, and when the second elastic member 212 is engaged with the second limiting groove 112, the first elastic member 211 is compressed and abuts against the surface of the insert base 21. In order to reduce the impact on the service life of the first elastic member 211 and the second elastic member 212 due to long-term 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 arranged between the first limiting groove 111 and the second limiting groove 112; at the same time, the first elastic member 211 and the second elastic member 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 member 211 is located in the first limiting groove 111, and the second elastic member 212 is located in the third limiting groove 113, so that a certain accommodation space can be provided for the second elastic member 212 to prevent the second elastic member 212 from being compressed for a long time and damaged, thereby affecting its resilience; when the insert assembly 2 is in the second position, the second elastic member 212 is located in the second limiting groove 112, and the first elastic member 211 is located in the third limiting groove 113, so that a certain accommodation space can be provided for the first elastic member 211 to prevent the first elastic member 211 from being compressed for a long time and damaged, thereby affecting its resilience. Of course, in order to facilitate the movement of the plug assembly 2 so that the first elastic member 211 and the second elastic member 212 can smoothly escape from the third limiting groove 113, guide slopes can be set at both ends of the third limiting groove 113, or corresponding guide structures can be set on the first elastic member 211 and the second elastic member 212, or the third limiting groove 113 can also pass through the side wall of the shell 1, and a corresponding paddle structure can also be set on the outer side of the third limiting groove 113, and the present embodiment does not impose any restrictions on this.

[0055] Optionally, in this embodiment, the first elastic member 211 is a first limiting elastic piece, and the second elastic member 212 is a second limiting elastic piece. One end of the first limiting elastic piece in the first direction is fixedly connected to the insert base 21, and the other end in 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 elastic piece is squeezed by the inner wall of the housing 1 and bends towards the surface of the insert base 21. When the first limiting elastic piece enters the first limiting groove 111, the suspended end of the first limiting elastic piece pops outwards and can abut against the groove wall of the first limiting groove 111. Similarly, one end of the second limiting elastic piece in the first direction is fixedly connected to the insert base 21, and the other end in 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 second limiting elastic piece is squeezed by the inner wall of the housing 1 and bends towards the surface of the insert base 21. When the second limiting elastic piece enters the second limiting groove 112, the suspended end of the second limiting elastic piece pops outwards and can abut against the groove wall of the second limiting groove 112. Specifically, in this embodiment, the suspended ends of the first limiting elastic piece and the second limiting elastic piece are close to each other, and the fixed ends of the first limiting elastic piece and the second limiting elastic piece are far from each other.

[0056] Preferably, in this embodiment, the third limiting groove 113 is a blind groove provided on the inner wall of the housing 1 (i.e., it does not penetrate the side 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 play a role in limiting the first elastic member 211 and the second elastic member 212. Specifically, as shown in Fig. 7 and Figure 8As shown, when the insert component 2 is inserted into the housing 1 from left to right in the first direction, the second limiting elastic piece first enters the first limiting groove 111; then the second limiting elastic piece continues to move forward and enters the third limiting groove 113. At this time, the first limiting elastic piece enters the first limiting groove 111, and the suspended end of the first limiting elastic piece abuts against the right side wall of the first limiting groove 111, so that the insert component 2 cannot move to the right continuously. At the same time, the suspended end of the second limiting elastic piece abuts against the left side wall of the third limiting groove 113, so that the insert component 2 cannot move to the left either. In this way, the insert component 2 is locked at the first position, ensuring that the eight-shaped insert 22 will not retract into the housing 1 during the process of being inserted into the three-hole socket; then by pressing the first dial 121, the first limiting elastic piece is disengaged from the first limiting groove 111, and the insert component 2 is pushed to move to the right continuously until the second limiting elastic piece enters the second limiting groove 112 and the first limiting elastic piece enters the third limiting groove 113. At this time, the suspended end of the second limiting elastic piece abuts against the left side wall of the second limiting groove 112, so that the insert component 2 cannot move to the left. At the same time, the suspended end of the first limiting elastic piece abuts against the right side wall of the third limiting groove 113, so that the insert component 2 cannot move to the right continuously. In this way, the insert component 2 is locked at the second position, ensuring that the parallel insert 23 will not retract into the housing 1 during the process of being inserted into 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. By using a spring to push the positioning pins into the first limiting groove 111 or the second limiting groove 112, the locking of the position of the insert component 2 can also be achieved.

[0058] In this embodiment, to facilitate the installation of the insert component 2 and the circuit board 4 into the housing 1, one end of the housing 1 near the eight-shaped insert 22 is open, and the insert component 2 and the circuit board 4 are respectively slidably installed into the housing 1 along the first direction. Optionally, a first slide rail 131 extending along the first direction is provided on the inner wall of the housing 1, and a slider 215 is provided on the insert base 21. The slider 215 is slidably connected to the first slide rail 131, thus realizing the guiding and limiting functions for the insert component 2, enabling the insert component 2 to be installed into the housing 1 more precisely and smoothly, improving the assembly efficiency, and facilitating the disassembly and maintenance of the insert component 2; moreover, the setting of the first slide rail 131 effectively improves the smoothness of the insert component 2 moving along the first direction. Preferably, the above slider 215 is a slide bar extending along the first direction for better sliding cooperation with the first slide rail 131. Of course, in other embodiments, the slider 215 can also be provided on the inner wall of the housing 1, and the first slide rail 131 can be provided on the insert base 21, which can also realize the sliding connection between the insert base 21 and the housing 1.
