The power adapter 100 may include a first housing 10, a second housing 20 engaged with the first housing 10, an electronic assembly 30 disposed in the first housing 10 and the second housing 20, a first connector 40 disposed in the first housing 10, a second connector 50 capable of being extending out of or retracting into the second housing 20, and an ejector mechanism 60 received in the first housing 10 and the second housing 20 and configured to drive the second connector 50 to be extended out of or retracted into the second housing 20.
The first housing 10 may be engaged with the second housing 20 to form a housing. An accommodating cavity 101 is defined in the housing and configured to accommodate and protect components (such as a printed circuit board, and a transformer, an inductor, a capacitor, a control integrated circuit on the printed circuit board, etc.) in the power adapter 100. The first housing 10 is rotatable around an axis relative to the second housing 20, and the second housing 20 is also rotatable around the same axis relative to the first housing 10. The electronic assembly 30 is arranged in the accommodating cavity 101 and configured to realize a current conversion or a voltage conversion. For example, the electronic assembly 30 is configured to convert the AC input to the DC output. The first connector 40 and the second connector 50 are electrically connected to the electronic assembly 30, respectively. The second connector 50 is at least partially located inside the accommodating cavity 101 or outside the accommodating cavity 101, in response to a relative rotation between the first housing 10 and the second housing 20. One of the first connector 40 and the second connector 50 is configured to be connected to an AC power source (e.g., 110-220 VAC) to allow the power adapter 100 to receive an AC from the AC power source. The other one of the first connector 40 and the second connector 50 is configured to be connected to an electronic device to allow the power adapter 100 to serve as a DC power source (e.g., 5-24 VDC) to output a DC to the electronic device.
In an embodiment, the first connector 40 may be configured in the same manner as the second connector 50, such that the first connector 40 is at least partially located inside the accommodating cavity 101 or outside the accommodating cavity 101 in response to the relative rotation between the first housing 10 and the second housing 20.
In some embodiments, the number of the connectors, such as the first connector 40 and the second connector 50, may be one. For example, the first connector 40 may be omitted, and the electronic assembly 30 is connected to the AC power source (e.g., 110-220 VAC) through the second connector 50, such that the power adapter 100 receives the AC from the AC power source. The electronic assembly 30 is directly connected to the electronic device rather than connected to the electronic device through the first connector 40. That is, the power adapter 100 is a part of the electronic device.
In another embodiment, the number of the connectors, such as the first connector 40 and the second connector 50, may be at least two. For example, the number of the first connector 40 is two, and two electronic devices may be connected through the first connector 40.

In the description of the present disclosure, it should be noted that, "a plurality of" means two or more, such as two, three, etc., unless specified otherwise.
It can be understood that names such as "first housing", "second housing", and "housing", etc., are interchangeable. For example, "first housing" may also be referred to as "second housing".
It can be understood that names such as "first connector", "second connector", and "connector", etc., are interchangeable. For example, "first connector" can also be referred to as "second connector".
As shown in FIGS. 5-7, FIG. 5 is a structural schematic view of a first housing 10 shown in FIG. 3, FIG. 6 is a structural schematic view of the first housing 10 in FIG. 5 from another perspective, and FIG. 7 is a cross-sectional view of the first housing 10 in FIG. 5. The first housing 10 may be made of any suitable material, e.g., plastic, rubber, ceramic, silicon, etc. Although the first housing 10 is shown as a cylindrical shape, however, the shape of the first housing 10 is not limited thereto. The first housing 10 may have any of other shapes required for a particular application. For example, the first housing 10 may have one of a rectangular shape, a spherical shape, an irregular shape, etc.
The first housing 10 may include a first bottom plate 11 and a first side plate 12 surrounding or enclosing the first bottom plate 11. The first side plate 12 is connected to the first bottom plate 11 to form the first housing 10 with a first receiving cavity 13 inside. The first receiving cavity 13 of the first housing 10 may be configured to receive components in the power adapter 100 such as a part or a whole of the electronic assembly 30 and the first connector 40. Of course, the first receiving cavity 13 of the first housing 10 may also be configured to only receive a portion of the first connector 40. In some embodiments, the first housing cavity 13 may form a part of the accommodating cavity 101. Of course, in some embodiments, the first receiving cavity 13 may also form the whole of the accommodating cavity 101.
The first bottom plate 11 has a circular plate-like structure. The first bottom plate 11 may have other shapes, such as the rectangular shape, a polygonal shape, an irregular shape, etc., which may be changed according to actual situations. A through hole 111 may be defined in the first bottom plate 11, and the through hole 111 penetrates the first bottom plate 11. The through hole 111 is in communication with the first receiving cavity 13, and is configured to receive the first connector 40. In some embodiments, the first connector 40 may be extended out of the first receiving cavity 13 via the through hole 111.
Understandably, the number of the through hole 111 may be at least one. Of course, the number of the through hole 111 may be determined based on the number of the first connector 40 and particular application requirements. In another embodiment, the through hole 111 may be omitted. In some embodiments, the through hole 111 may be replaced by a recess. For example, the recess is defined in the first bottom plate 11 to accommodate the first connector 40, such that the first connector 40 is located outside the first receiving cavity 13.
The first side plate 12 may have a cylindrical tubular structure, which is not limited thereto. A shape of the first side plate 12 may be changed according to the actual situations, which is not repeated herein. The first side plate 12 extends from an edge of the first bottom plate 11 towards a side away from the first bottom plate 11, and a first opening 14 is defined accordingly. The first side plate 12 is engaged with the second housing 20 at a position where the first opening 14 is defined.
The first side plate 12 and the first bottom plate 11 may be of an integral structure. In an embodiment, the first side plate 12 may be glued to the first bottom plate 11 to form the first housing 10. In an embodiment, the first side plate 12 may be fixed to the first bottom plate 11 to form the first housing 10 by means of threads or a buckle, such that the first bottom plate 11 is detachably connected to the first side plate 12. It will be understood that the through hole 111 may also be defined in the first side plate 12 when the first side plate 12 is connected to the first bottom plate 11 to form the first housing 10. That is, the through hole 111 may be defined in the first bottom plate 11 and/or the first side plate 12.
As shown in FIGS. 5-7, the first housing 10, such as the first side plate 12, is provided with a first buckling member 121 at the position where the first opening 14 is defined, such that the first housing 10 is engaged with the second housing 20. The first buckling member 121 may include a connecting plate 1211, and the connecting plate 1211 extends from an edge of the first side plate 12 at the position where the first opening 14 is defined towards a side away from the first side plate 12. A groove 1213 is defined in the connecting plate 1211. The groove 1213 is configured to be engaged with a corresponding portion of the second housing 20, such that the first housing 10 is engaged with the second housing 20. In some embodiments, the first buckling member 121 may also be configured as other structures arranged on the first side plate 12, and the other structures may include at least one of a bump, a buckling hook, a buckling slot, and the like.
The connecting plate 1211 may be an annular structure. The groove 1213 may also be an annular structure. The groove 1213 is defined at an outer side of the connecting plate 1211, such that the second housing 20 is sleeved on the connecting plate 1211 and engaged with or stuck in the groove 1213. In this way, the second housing 20 is rotatable relative to the first housing 10 along a circular track configured by the groove 1213. Of course, the groove 1213 may also be defined at an inner side of the connecting plate 1211. Understandably, the number of the grooves 1213 may also be multiple, and multiple grooves 1213 are defined in the connecting plate 1211 side by side. In an embodiment, the groove 1213 may have a discontinuous structure.
By means of the first buckling member 121, the first housing 10 is engaged with the second housing 20, and a part structure of the second housing 20 is disposed in the groove 1213 and slidable in the groove 1213. When the first housing 10 (such as the first buckling member 121) is connected to the second housing 20, the second housing 20 is allowed to be rotated around the axis relative to the first housing 10 under a force.
In an embodiment, a plurality of slits 1215 may be defined in the connecting plate 1211 to divide the connecting plate 1211 into a plurality of sections. As shown in FIG. 6, two slits 1215 are defined in the connecting plate 1211 to divide the connecting plate 1211 into two sections. It will be appreciated that, with the slits 1215, each of the connecting plates 1211 forms one first buckling member 121, that is, a plurality of first buckling members 121 may be arranged on the first side plate 12. In an embodiment, no groove 1213 is defined in some of the connecting plates 1211.
Understandably, the slits 1215 defined in the connecting plate 1211 are configured to allow the first buckling members 121 to have deformation spaces at positions where the slits 1215 are defined, such that each of the connecting plates has an elastic deformation capability. In an engaging process of the first housing 10 with the second housing 20, the connecting plates 1211 generate elastic deformation to provide clearance for a part structure of the second housing 20. In this way, a possibility of damaging the first housing 10 and/or the second housing 20 during an assembly process or a disassembly process may be reduced.
As shown in FIGS. 5-7, the first housing 10, such as the connecting plate 1211, is also provided with a mounting component 122. The mounting component 122 is configured to mount some of components configured to fix the electronic assembly 30. The number of the mounting components 122 may be two, i.e., a first mounting component 1221 and a second mounting component 1223. Of course, the number of the mounting components 122 may be adjusted according to actual needs. For example, the number of the mounting components 122 may be not limited to two, such as one or three.
Both the first mounting component 1221 and the second mounting component 1223 may have plate-like structures. Both the first mounting component 1221 and the second mounting component 1223 extend from an edge of the first buckling member 121 (such as the connecting plate 1211) to a side away from the first buckling member 121. The first mounting component 1221 and the second mounting component 1223 may be arranged substantially symmetrically.
Understandably, the mounting component 122 may be arranged on the first buckling member 121 (such as the connecting plate 1211). The mounting component 122 and the first buckling member 121 may be of an integral structure. The first buckling member 121 is configured to fix the electronic assembly 30. In an embodiment, the mounting component 122 may be directly arranged on the first side plate 12. For example, the mounting component 122 may extend from an edge of the first side plate 12 at the first opening 14 to a side away from the first side plate 12. In some embodiments, the mounting component 122 may also be arranged on the ejector mechanism 60. In some embodiments, the mounting component 122 may also be omitted.
As shown in FIG. 8-9, FIG. 8 is a structural schematic view of the second housing 20 shown in FIG. 3, and FIG. 9 is a partial cross-sectional view of the second housing 20 in FIG. 8. The second housing 20 may be made of any suitable material, e.g., plastic, rubber, ceramic, silicon, etc. Although the second housing 20 is shown as a cylindrical shape, however, the shape of the second housing 20 is not limited thereto. The second housing 20 may have any of other shapes required for the particular application. For example, the second housing 20 may have one of a rectangular shape, a spherical shape, or an irregular shape, etc.
The second housing 20 may include a second bottom plate 21 and a second side plate 22. The second side plate 22 surrounds or is enclosed around the second bottom plate 21 and is connected to the second bottom plate 21 to form the second housing 20 with a second receiving cavity 23. The second side plate 22 may further enclose at a side of the second side plate 22 opposite to the second bottom plate 21 to form or define a second opening 24, such that the second side plate 22 is engaged with the first housing 10 (such as the first buckling member 121) at a position where the second opening 24 is defined. The second receiving cavity 23 is configured to receive the components in the power adapter 100 such as the part of the electronic assembly 30 and the second connector 50. The second housing 20 is engaged with the first housing 10 to form the accommodating cavity 101. That is, the second receiving cavity 23 may form a part of the accommodating cavity 101. Of course, in some embodiments, the second receiving cavity 23 may also form the whole of the accommodating cavity 101.
The second bottom plate 21 has a circular plate-like structure. The second bottom plate 21 may have other shapes, such as the rectangular shape, the polygonal shape, or the irregular shape, etc., which may be changed according to the actual situations. A channel 211 is defined in the second bottom plate 21 and penetrates the second bottom plate 21. In some embodiments, the channel 211 may include a first channel 2111 and a second channel 2113. The channel 211, such as the first channel 2111 and the second channel 2113, is in communication with the second receiving cavity 23. The second connector 50 is extended out of the channel 211 (such as the first channel 2111 or the second channel 2113) or retracted into the second receiving cavity 23,.
Understandably, the number of the channel 211 may be one or multiple, which is determined according to the number of the second connector 50 and the particular application requirements. In some embodiments, the first channel 2111 or the second channel 2113 may be omitted. In some embodiments, the channel 211 may also be omitted.
The second bottom plate 21 is provided with a protrusion 212. The protrusion 212 is configured to be connected to the ejector mechanism 60 to stabilize or fix the ejector mechanism 60.
In some embodiments, the protrusion 212 may be omitted. In some embodiments, the protrusion 212 may also be replaced by a recess or a through hole. That is, the recess or the through hole may be defined in the second bottom plate 21, and the ejector mechanism 60 may extend into the recess or the through-hole, such that the second bottom plate 21 is connected to the ejector mechanism 60. In this way, the ejector mechanism 60 is stabilized or fixed.
In an embodiment, the second side plate 22 may have a circular tubular structure. The second side plate 22 may also have other shapes, and the shape of the second side plate 22 may be designed according to the actual situations, which is not repeated herein. The second side plate 22 extends from an edge of the second bottom plate 21 towards a side away from the second bottom plate 21, and the second opening 24 is defined accordingly. The second side plate 22 is engaged with the first housing 10 (such as the first buckling member 121) at the position where the second opening 24 is defined. The second side plate 22 and the second bottom plate 21 may be of an integral structure. In an embodiment, the second side plate 22 may be glued to the second bottom plate 21 to form the second housing 20. In an embodiment, the second side plate 22 may be fixed to the second bottom plate 21 to form the second housing 10 by means of threads or a buckle, such that the second bottom plate 21 is detachably connected to the second side plate 22. It will be understood that the channel 211 (such as the first channel 2111 and the second channel 2113) may also be defined in the second side plate 22 when the second side plate 22 is connected to the second bottom plate 21 to form the second housing 20. That is, the channel 211 may also be defined in the second bottom plate 21 and/or the second side plate 22.
As shown in FIG. 8, an anti-slip pattern 221 is defined on an outer surface of the second housing 20 (such as the second side plate 22), which is convenient for the user to hold the second housing 20 and further rotate the second housing 20. In this way, the second housing 20 is enabled to be rotated around the axis relative to the first housing 10.
The second housing 20 (such as the second side plate 22) is provided with a guiding component 222 in the second receiving cavity 23. In some embodiments, the guiding component 222 may include, for example, a first guiding component 2221 and a second guiding component 2223. The guiding component 222, such as the first guiding component 2221 and the second guiding component 2223, may be configured to be connected to the second connector 50, to guide the second connector 50 to be slid in a direction of extension of the guiding component 222 (such as the first guiding component 2221 and the second guiding component 2223), such that the second connector 50 is able to be extended out of the channel 211 of the second housing 20 or retracted into the second receiving cavity 23. The guiding component 222 (such as the first guiding component 2221 and the second guiding component 2223) may have a rod-like shape or a plate-like shape. In an embodiment, the first guiding component 2221 and the second guiding component 2223 may be arranged substantially symmetrically. In an embodiment, the number of the guiding component 222 may be at least one. For example, one of the first guiding component 2221 and the second guiding component 2223 may be omitted.
It is understood that, since the guiding component 222 (such as the first guiding component 2221 and the second guiding component 2223) is arranged in the second receiving cavity 23, the guiding component 222 (such as the first guiding component 2221 and the second guiding component 2223) may also be arranged on the second bottom plate 21 rather than the second side plate 22. In some embodiments, the guiding component 222 (such as the first guiding component 2221 and the second guiding component 2223) may be arranged on both the second bottom plate 21 and the second side plate 22.
As shown in FIG. 9, a second buckling member 223 may be arranged on a portion of the second housing 20 (such as the second side plate 22) where the second opening 24 is defined, such that the second housing 20 is engaged with the first housing 10 (such as the first buckling member 121) via the second buckling member 223. The second buckling member 223 is a flange extending from an edge of the second side plate 22 where the second opening 24 is defined towards a side away from the second side plate 22. The second buckling member 223 is engaged in the groove 1213, such that the second buckling member 223 is buckled with the first buckling member 121 and slidable in the groove 1213. In some embodiments, the second buckling member 223 may be at least one of a bump, a buckling hook, a buckling slot, and the like, which is determined according to different structures of the first buckling member 121. It can be understood that the flange may have a discontinuous structure.
In an embodiment, both the first buckling member 121 and the second buckling member 223 may be replaced by a magnet or an electromagnet to achieve the connection between the first housing 10 and the second housing 20.
As shown in FIG. 10, FIG. 10 is a structural schematic view illustrating an assembly of the first housing 10 and the second housing 20 shown in FIG. 3. When the first housing 10 is engaged with the second housing 20, the first buckling member 121 is engaged with the second buckling member 223. In an embodiment, the second buckling member 223 is sleeved on an outer side of the first buckling member 121, and the second buckling member 223 is disposed in the groove 1213 defined in the connecting plate 1211 and slidable in the groove 1213, such that the second housing 10 is enabled to be rotated around the axis relative to the second housing 20.
It can be understood that names "first buckling member", "second buckling member", and "buckling member" can be interchanged. For example, the "first buckling member" may also be referred to as the "second buckling member".
As shown in FIGS. 11-14, FIG. 11 is a structural schematic view illustrating an assembly of an electronic assembly 30 and a first connector 40 shown in FIG. 3, FIG. 12 is a structural schematic view of a conductive component shown in FIG. 11, FIG. 13 is a structural schematic view illustrating an assembly of the first housing 10, the electronic assembly 30, and the first connector 40 shown in FIG. 3, and FIG. 14 is a structural schematic view illustrating an assembly of the first housing 10 and the electronic assembly 30 shown in FIG. 13. It should be noted that the ejector mechanism 60 is removed in FIG. 13 in order to better describe and show a connection relationship between one or more conductive components 32 and the first housing 10. The electronic assembly 30 may be configured to implement the DC output of the first connector 40 and the AC input of the second connector 50. The electronic assembly 30 may include a printed circuit board 31 and the one or more conductive components 32. The printed circuit board 31 is electrically connected to the one or more conductive components 32. The printed circuit board 31 is electrically connected to the first connector 40. The one or more conductive components 32 are electrically connected to the second connector 50. The printed circuit board 31 may be configured to implement a conversion between the AC and the DC.
The printed circuit board 31 may be mounted in the first receiving cavity 13 of the first housing 10. The printed circuit board 31 includes a circuit formed thereon, such as a common mode choke, the transformer, the control integrated circuit, a high voltage circuit (e.g., AC), a low voltage circuit (e.g., DC), a filter circuit, or the like. The printed circuit board 31 may include a component such as the capacitor, the inductor, a resistor, a transistor, or the like. The printed circuit board 31 may be manufactured by any one of conventional techniques. Conductive pins may be arranged on the printed circuit board 31 and configured to be connected to and fix the first connector 40 and the one or more conductive components 32.
In an embodiment, the printed circuit board 31 may also be provided with a Bluetooth module.

The electronic assembly 30 may also include a battery, a button, an indicator, a buzzer, and a speaker, etc., which are arranged on the first housing 10. The battery is configured to supply power for the Bluetooth module, the indicator, the buzzer, and the speaker, etc. Some functions of the power adapter, such as controlling the Bluetooth module to be paired with the electronic device, sending a Bluetooth signal, and the battery discharging, may be controlled through the button. In some embodiments, the power adapter 100 is allowed to serve as a portable charger due to the existence of the battery.
Understandably, it is easy for the user to forget a position of the power adapter 100 due to a small volume of the power adapter 100. In this case, the Bluetooth module is configured to allow the power adapter 100 to be paired with the electronic device such as the cell phone, the laptop, and the like, so as to achieve a communication connection between the power adapter 100 and the electronic device, and achieve the following functions.
Within a coverage of the Bluetooth, the electronic device, such as the cell phone and the laptop, sends a control signal searching for the power adapter 100 to the power adapter 100 through the Bluetooth module. Under the control of the control signal, the power adapter 100 may show position information thereof through a specific beep, sound, light, etc., to inform the user of the position thereof.
Within the coverage of the Bluetooth, when the button on the power adapter 100 is pressed down, the power adapter 100 sends another control signal searching for the electronic device (such as the cell phone, and the laptop, etc.) to the electronic device (such as the cell phone, and the laptop, etc.) paired with the power adapter 100 via the Bluetooth module. The electronic device (such as the cell phone, and the computer, etc.) shows position information thereof through a specific ring tone, light, etc., to inform the user of the position thereof.
As shown in FIGS. 12 and 13, the one or more conductive components 32 may be made of a solid conductive metal material such as gold, silver, iron, copper, aluminum, or an alloy. The number of the one or more conductive components 32 may be two, i.e., the one or more conductive components 32 include a first conductive component 32a and a second conductive component 32b. Of course, the number of the one or more conductive components 32 may be adjusted according to the actual situations and is not limited to two. For example, the number of the one or more conductive components 32 may also be three or four. The one or more conductive components 32 may be fixed to the first housing 10 (such as the mounting component 122). In an embodiment, the first conductive component 32a may be fixed to the first mounting component 1221, and the second conductive component 32b is fixed to the second mounting component 1223. The one or more conductive components 32 (such as the first conductive component 32a and the second conductive component 32b) may extend into the first receiving cavity 13 of the first housing 10 to be electrically connected to the conductive pins of the printed circuit board 31. The one or more conductive components 32 (such as the first conductive component 32a and the second conductive component 32b) may be electrically connected to the second connector 50, such that an electrical path is constructed between the printed circuit board 31 and the second connector 50.
As shown in FIGS. 13 and 14, each of the conductive components 32 (such as the first conductive component 32a and the second conductive component 32b) may include a fixing component 321 configured to be engaged with, e.g., fixedly engaged with, a corresponding one of the mounting components 122, an extension component 322 extending from the fixing component 321, and an abutting component 323. The extension component 322 extends from the fixing component 321 into the first receiving cavity 13 and is electrically connected to the conductive pins of the printed circuit board 31. In an embodiment, the extension component 322 is connected to the conductive pins of the printed circuit board 31 by means of welding. The extension component 322 may be bent from an edge of the fixing component 321 in a bending manner, such that the extension component 322 and the fixing component 321 are located on two opposite side surfaces of the corresponding one of the mounting components 122, respectively. The extension component 322 then extends towards the first receiving cavity 13. The abutting component 323 is bent upwards from a middle at bottom edge of the fixing component 321. The abutting component 323 is configured to abut against the second connector 50 to construct an electrical path therebetween.
As shown in FIG. 14, the fixing component 321 may surround or enclose around a side surface of the corresponding one of the mounting components 122, e.g., the first mounting component 1221. The fixing component 321 includes a first engaging portion 3211 and a second engaging portion 3213. The first engaging portion 3211 and the second engaging portion 3213 are engaged with an edge of the corresponding one of the mounting components 122, e.g., the first mounting component 1221, respectively, such that the fixing component 321 is fixedly connected to the corresponding one of the mounting components 122, e.g., the first mounting component 1221. Understandably, the fixing component 321 may also be fixedly connected to the corresponding one of the mounting components 122, e.g., the first mounting component 1221 by other means, such as through a screwed structure, a glued structure, etc. In an embodiment, the first engaging portion 3211 and the second engaging portion 3213 may have hook-like structures formed by bending both edges of the fixing component 321, respectively.
In an embodiment, the first engaging portion 3211 is arranged on a first end of the fixing component 321, the second engaging portion 3213 is arranged on a second end of the fixed component 321, and the first end is opposite to the second end. In some embodiments, at least one third engaging portion 3215 is arrange between the first end and the second end of the fixing component 321. The third engaging portion 3215 is configured to be fixed to another edge of the corresponding one of the mounting components 122, e.g., the first mounting component 1221. The third engaging portion 3215 may also have the hook-like structure formed by bending another edge of the fixing component 321.
The extension component 322 and the fixing component 321 may be of an integral structure. The extension component 322 may extend from the edge of the fixing component 321. In an embodiment, the fixing component 321 may be directly fixed to the ejector mechanism 60 rather than fixed to the corresponding one of the mounting components 122. In an embodiment, the fixing component 321 may be omitted, the extension component 322 is fixedly connected to the abutting component 323, and each of the one or more conductive components 32 is fixed to the ejector mechanism 60 through the extension component 322, such that the conductive component 32 is fixed to the ejector mechanism 60. In an embodiment, both the fixing component 321 and the extension component 322 are omitted.
The abutting component 323 is a strip-like structure and has two ends opposite to each other. One of the two ends of the abutting component 323 is fixedly connected to the fixing component 321 by means of, for example, welding, gluing, screwing, and the like. The other end of the abutting component 323 abuts against the second connector 50 to construct an electrical path among the printed circuit board 31, the second connector 50, and the abutting component 323.
In an embodiment, the abutting component 323 has a property of the elastic deformation. A reliable electrical connection between the abutting component 323 and the second connector 50 may be achieved through the elastic deformation of the abutting component 323. In an embodiment, the abutting component 323 and the fixing component 321 may be of an integral structure. The abutting component 323 extends from the edge of the fixing component 321. In an embodiment, the fixing component 321 and the extension component 322 are omitted, and the abutting component 323 is fixed to the first housing 10 or the ejector mechanism 60. The abutting component 323 is electrically connected to the printed circuit board 31 to construct an electrical path between the abutting component 323 and the printed circuit board 31.
As shown in FIGS. 3 and 4, the first connector 40 is electrically connected to the conductive pins of the printed circuit board 31 for outputting the DC. The first connector 40 is configured to be cooperated with the electronic device, e.g., the first connector 40 may be a USB connector. The first connector 40 may also be any of other connectors. The power adapter 100 may be coupled to the electronic device via the first connector 40 to supply the power to the electronic device or charge the electronic device. For example, one end of a cable with a complementary USB connector may be connected to the first connector 40, and the other end of the cable may have any of other suitable connectors which is configured to be cooperated with the electronic device. These connectors include but are not limited to, a µUSB connector, a 30-pin connector employed by a device of Apple Inc., a Lightning^® connector employed by the device of the Apple Inc., a Type-C connector, etc.
In some embodiments, the first connector 40 is an electromagnetic induction coil and configured to supply the power to the electronic device or charge the electronic device through electromagnetic induction between the first connector 40 and the electronic device.
In an embodiment, the first connector 40 may have a cable electrically connected to the printed circuit board 31, e.g., the conductive pins of the printed circuit board 31. The first connector 40 is directly connected to a connector on the electronic device. In an embodiment, the first bottom plate 11 and the first side plate 12 are designed to be detachable from each other. The first connector 40 having the cable may be disposed in the first receiving cavity 13 for storage.
As shown in FIGS. 15 and 16, FIG. 15 is a structural schematic view of a second connector 50 in FIG. 3, and FIG. 16 is a cross-sectional view of the power adapter 100 in FIG. 3. The second connector 50 is mounted in the first housing 10 and the second housing 20. The second connector 50 is configured to be cooperated with a corresponding outlet connector (e.g., a wall outlet) which provides the AC power. The second connector 50 abuts against the conductive component 32 (such as the abutting component 323) to construct an electrical path between the second connector 50 and the electronic assembly 30 (such as the abutting component 323).
The second connector 50 includes a conductive member 51 and a mounting base 52. The conductive member 51 is configured to be cooperated with the corresponding outlet connector (e.g., the wall outlet) which provides the AC power to achieve an electrical connection. The conductive member 51 may be a pin. For example, the conductive member 51 may include a first pin 511 and a second pin 512. The conductive member 51 (such as the first pin 511 and the second pin 512) is fixed to the mounting base 52. The mounting base 52 may be made of a rigid insulating material. The mounting base 52 may be connected to the ejector mechanism 60. The ejector mechanism 60 is configured to drive the mounting base 52 to move in response to the relative rotation between the first housing 10 and the second housing 20, such that the conductive member 51 (such as the first pin 511 and the second pin 512) is extended out of or retracted into the second receiving cavity 23.
A slide-way 521 is defined in the mounting base 52 and configured to receive the guiding component 222 of the second housing 20. The mounting base 52 is slidable in the direction of the extension of the guiding component 222. The mounting base 52 is connected to the second housing 20 through a relationship between the slide-way 521 and the guiding component 222. In an embodiment, the slide-way 521 may have a structure such as a hole or a groove. The number of the slide-way 521 is at least one. As shown in FIG. 15, the number of the slide-way 521 is two. The slide-way 521 extends along a direction substantially parallel to an axis of the guiding component 222.
The mounting base 52 may be slidable relative to the second housing 20 along the direction of the extension of the guiding component 222, such that the mounting base 52 is pushed or pulled by the ejector mechanism 60 in response to the relative rotation between the first housing 10 and the second housing 20. As a result, the conducting member 51 (such as the first pin 511 and the second pin 512) is driven to be slid relative to the second housing 20, such that the conducting member 51 (such as the first pin 511 and the second pin 512) is at least partially located inside the second receiving cavity 23 or outside the second receiving cavity 23.
The number of the pins, such as the first pin 511 and the second pin 512, may be adjusted according to the actual situations. For example, the pins may also include a third pin.
As shown in FIGS. 15 and 16, the conductive member 51, e.g., the first pin 511 is fixed to the mounting base 52. The conductive member 51, e.g., the first pin 511 abuts against the first conductive component 32a, such as the abutting component 323 of the first conductive component 32a. In an embodiment, an end of the first pin 511 is fixed to the mounting base 52, and an end portion of the first pin 511 fixed to the mounting base 52 abuts against the first conductive component 32a, such as abutting against the abutting component 323 of the first conductive component 32a.
The conductive member 51, e.g., the second pin 512 is fixed to the mounting base 52. The second pin 512 abuts against the second conductive component 32b, such as the abutting component 323 of the second conductive component 32b. In an embodiment, an end of the second pin 512 is fixed to the mounting base 52, and an end portion of the second pin 512 fixed to the mounting base 52 abuts against the second conductive component 32b, such as abutting against the abutting component 323 of the second conductive component 32b.
Understandably, the conductive member 51 may also be a connecting head of a connector such as the µUSB connector, the 30-pin connector employed by the device of the Apple Inc., the Lightning^® connector employed by the device of the Apple Inc., and the Type-C connector, etc. That is, the second connector 50 may be replaced by the first connector 40 shown in FIGS. 2 and 3. The first connector 40 shown in FIGS. 2 and 3 may be connected to the first housing 10 and the second housing 20 in the same way of the second connector 50.
As shown in FIG. 17, FIG. 17 is a structural schematic view illustrating an assembly of the second housing 20 and the second connector 50 shown in FIG. 16. When the second connector 50 is connected to the second housing 20, the conductive member 51 of the second connector 50 extends or is inserted into the second receiving cavity 23, and the guiding components 222 of the second housing 20, such as the first guiding component 2221 and the second guiding component 2223, are disposed in a corresponding slide-way 521 of the mounting base 52 of the second connector 50, respectively. The mounting based 52 is allowed to be slidable relative to the second housing 20 in the direction of the extension of the guiding components 222. For example, in a process of the mounting base 52 sliding relative to the second housing 20, the first pin 511 of the second connector 50 is extended out of the first channel 2111 of the channel 211 or retracted into the second receiving cavity 23, and the second pin 512 of the second connector 50 is extended out of the second channel 2113 of the channel 211 or retracted into the second receiving cavity 23. It will be appreciated that in a process of the mounting base 52 sliding relative to the second housing 20, functions of the guiding components 222 are weakened since the channels 211 may also serve as guiders. Consequently, in some embodiments, the guiding components 222 and the slide-way 521 may be omitted.
As shown in FIG. 18, FIG. 18 is a structural schematic view illustrating an assembly of the first housing 10, the second housing 20, the second connector 40, and an ejector mechanism 60 shown in FIG. 3. The ejector mechanism 60 is configured to drive the second connector 50 to be extended out of or retracted into the second housing 23 in response to the first housing 10 being rotated around the axis relative to the second housing 20. The ejector mechanism 60 may include an ejector component 15, the mounting base 52, and the guiding components 222. The ejector member 15 may be arranged on the first housing 10, such as the first side plate 12. The mounting base 52 is connected to the ejector component 15. The mounting base 52 is slidably connected to the guiding components 222. The ejector component 15 is configured to drive the mounting base 52 to slide in the direction of the extension of the guiding components 222 in response to the second housing 20 being rotated around the axis relative to the first housing 10, such that the conductive member 51 mounted on the mounting base 52 is at least partially located inside or outside the second receiving cavity 23. In an embodiment, the guiding components 222 may be omitted.
As shown in FIG. 19, FIG. 19 is a structural schematic view of the first housing 10 shown in FIG. 18. The ejector component 15 may be made of a rigid material, such as the plastic, the glass, the rubber, the ceramic, the silicon, etc. Of course, the ejector component 15 may also be made of the same material as the first housing 10. The ejector component 15 may also be made of other materials. The ejector component 15 is arranged at a position of the first side plate 12 where the first opening 14 is defined. The ejector component 15 may include a push-pull rod 151 and a connecting component 152. The connecting component 152 is fixed to the first housing 10 (such as the first side plate 12). The push-pull rod 151 is fixed to the connecting component 152 and configured to be connected to the mounting base 52. An axis of the push-pull rod 151 may be substantially coincided with the axis around which the first housing 10 is rotated relative to the second housing 20. The ejector component 15 (such as the push-pull rod 151) is rotated in response to the relative rotation between the first housing 10 and the second housing 20, so as to push or pull the second connector 50, such as the mounting base 52 of the second connector 50. In this way, the second connector 50 is at least partially located inside or outside the second receiving cavity 23.
In some embodiments, the push-pull rod 151 is a screw rod and connected to the second connector 50 by threads. The push-pull rod 151 may be directly fixed to the connecting component 152. In an embodiment, the push-pull rod 151 is connected to the second housing 20. For example, an accommodating slot 1511 is defined in an end portion of the push-pull rod 151 close or adjacent to the second housing 20. The protrusion 212 is arranged or received in the accommodating slot 1511, such that the push-pull rod 151 is inserted into and engaged with the second housing 20. In this way, a stability of the push-pull rod 151 is improved.
As shown in FIG. 20, FIG. 20 is a structural schematic view of the first housing 10 shown in FIG. 19. The connecting component 152 may have a plate-like structure. Of course, the connecting component 152 may also have other shapes, such as a mesh shape, which is not repeated herein. An edge of the connecting component 152 is connected to the first side plate 12 at the position where the first opening 14 is defined. The first receiving cavity 13 is defined or enclosed by the connecting component 152, the first bottom plate 11, and the first side plate 12. The second receiving cavity 23 is defined or enclosed by the connecting component 152, the second bottom plate 21, and the second side plate 12. That is, the accommodating cavity 101 is divided by the connecting component 152 into two sections, i.e., the first receiving cavity 13 and the second receiving cavity 23, respectively.
One or more perforations may be defined in the connecting component 152 and penetrates the connecting component 152. In an embodiment, the perforations may include a first via hole 1521 and a second via hole 1523. The perforations (such as the first via hole 1521 and the second via hole 1523) may be in communication with the first receiving cavity 13. As shown in FIG. 24, the electronic assembly 30 (such as the extension component 322) may be disposed in one of the perforations (such as the first via hole 1521 or the second via hole 1523). Understandably, in case that the mounting components 122 are arranged on the ejector component 15, the mounting components 122 are arranged at a portion of the connecting component 152 close to the first side plate 12. Of course, in some embodiments, the first buckling member 121 may also be arranged on the connecting component 152. That is, the first buckling member 121 may be arranged on the connecting component 152 and/or the first side plate 12.
In some embodiments, the connecting component 152 may be omitted, and the push-pull rod 151 may be extended into the first receiving cavity 13 and directly connected to and fixed to the first housing 10 (such as the first bottom plate 11).
Understandably, the ejector component 15 and the first bottom plate 11 may be of an integral structure; or the ejector component 15 and the first side plate 12 may be of an integral structure.
As shown in FIGS. 21 and 22, FIG. 21 is a structural schematic view of the second connector 50 shown in FIG. 18, and FIG. 22 is a cross-sectional view of the second connector 50 shown in FIG. 21. A screw hole 522 is defined in the mounting base 52. The screw hole 522 is provided with threads matched with the threads on the push-pull rod 151, such that the push-pull rod 151 is extended into the screw hole 522 and threaded to the mounting base 52. In an embodiment, the threads formed in the screw hole 522 are configured to be continuous or discontinuous. When the threads of the screw hole 522 are discontinuous, as shown in FIG. 21, multiple bumps 523 are arranged in the screw hole 522. The push-pull rod 151 is configured to be disposed between the bumps 523, and the push-pull rod 151 is connected to the mounting base 52 through the bumps 523. The bumps 523 are configured to be slidable in a direction of extension of threads on a surface of the push-pull rod 151. In an embodiment, the number of the bumps 523 may be two, and the two bumps 523 are arranged substantially symmetrically. Of course, the number of the bumps 523 is not limited to two, but may also be three or four. An arrangement of the multiple bumps 523 may be adjusted according to the actual needs. In an embodiment, a direction of the axis of the push-pull rod 151 is substantially parallel to a direction of extension of the slide-way 521 or the direction of the extension of the guiding components 222.
As shown in FIG. 23, FIG. 23 is a structural schematic view illustrating an assembly of the ejector component 15 and the second connector 50 shown in FIG. 18. When the ejector component 15 is connected to the second connector 50, the end portion of the push-pull rod 151 is disposed in the screw hole 522 defined in the mounting base 52 of the second connector 50. The first housing 10 is rotated, such that the push-pull rod 151 is threaded to the second connector 50 (such as the mounting base 52).
As shown in FIG. 18, in response to the relative rotation between the first housing 10 and the second housing 20, the ejector component 15 (such as the push-pull rod 151) is configured to push the second connector 50 (such as the mounting base 52) to slide along the direction of the axis of the push-pull rod 151, such that the conductive member 51 is extended out of the second receiving cavity 23. In addition, the first pin 511 abuts against the abutting component 323 of the electronic assembly 30 (such as the abutting component 323 of the first conductive component 32a) and the second pin 512 abuts against the abutting component 323 of the electronic assembly 30 (such as the abutting component 323 of the second conductive component 32b), in response to the conductive member 51 (such as the first pin 511 and the second pin 512) being extended out of the second receiving cavity 23.
It will be appreciated that the push-pull rod 151 may also have a rod-like structure provided with a gear or a gear assembly. The push-pull rod 151 is connected to the mounting base 52 by means of gear engagement. The direction of the axis of the push-pull rod 151 may not be parallel to the direction of extension of the guiding components 222. In an embodiment, the mounting base 52 is provided with a rack configured to be engaged with a gear in the gear assembly. The push-pull rod 151 is engaged with the mounting base 52 through the rack and the gear assembly. The rack and the gear assembly herein are configured in a scope where a person skilled in the art may understand, which is not repeated herein.
It is understood that the push-pull rod 151 drives the mounting base 52, such that the second connector 50 is driven to move. The guiding components 222 (such as the first guiding component 2221 and the second guiding component 2223) are configured to guide the mounting base 52. In an embodiment, the mounting base 52 of the ejector mechanism 60 is omitted, and the guiding components 222 (such as the first guiding component 2221 and the second guiding component 2223) are configured as a part of the ejector mechanism 60.
In some embodiments, the mounting base 52 may be guided by the channels 211 (such as the first channel 2111 and the second channel 2113). Understandably, the mounting base 52 of the ejector mechanism 60 may be omitted, and the channels 211 (such as the first channel 2111 and the second channel 2113) may be configured as a part of the ejector mechanism 60.
During the assembly of the power adapter 100, as shown in FIGS. 11 and 13, the first connector 40 is fixedly welded to the conductive pins of the printed circuit board 31. The printed circuit board 31 and the first connector 40 are mounted in the first receiving cavity 13, and the first connector 40 corresponds to and faces the through hole 111, such that the first connector 40 is electrically connected to the electronic device by passing through the through hole 111. The fixing component 321 of each of the one or more conductive components 32 is engaged with the mounting component 122 through the first engaging portion 3211, the second engaging portion 3213, and the third engaging portion 3215. The extension component 322 passes through a corresponding one of the perforations (such as the first via hole 1521 and the second via hole 1523), and is fixedly welded to the conductive pins of the printed circuit board 31.
As shown in FIG. 23, the second connector 50 is mounted on the ejector component 15. The push-pull rod 151 is inserted into the screw hole 522 of the second connector 50, such that the second connector 50 (such as the mounting base 52) is threaded to the push-pull rod 151.
As shown in FIGS. 4 and 17, the first housing 10 is engaged with the second housing 20, and the pins of the second connector 50 correspond to and face the channels 211 one by one. For example, the first pin 511 corresponds to and faces the first channel 2111, and the second pin 512 corresponds to and faces the second channel 2113. The first pin 511 may extend out from the first channel 2111 and the second pin 512 may extend out from the second channel 2113. The second connector 50 (such as slide-ways 521) may be cooperated with the guiding components 222. That is, each of the first guiding component 2221 and the second guiding component 2223 is disposed in a corresponding one of slide-ways 521, respectively, such that the second connector 50 is slidable in the direction of the extension of the guiding components 222. In this way, the second connector 50 is slid out of the second receiving cavity 23 from the channels 211. In an embodiment, the first pin 511 and the second pin 512 are slid out of the second receiving cavity 23, respectively from the first channel 2111 and the second channel 2113. The first buckling member 121 is engaged with the second buckling member 223.
As shown in FIGS. 16 and 17, during the usage, the first housing 10 is held, and the second housing 20 is rotated. Due to the threads, the mounting base 52 and the push-pull rod 151 are rotated relative to each other. The mounting base 52 is moved along the direction of the axis of the push-pull rod 151 through the cooperation between the guiding components 222 (such as the first guiding component 2221 and the second guiding component 2223) and the mounting base 52. The first pin 511 and the second pin 512 are driven by the mounting base 52 to be extended out of or retracted into the second receiving housing 23 by changing a direction of rotation of the second housing 20.
FIGS. 24 and 25 shows a cross-sectional view of the power adapter 100 shown in FIG. 3, respectively. When the first pin 511 and the second pin 512 are at least partially located outside the second receiving cavity 23, the abutting component 323 of the first conductive component 32a abuts against the first pin 511, and the second abutting component 323 of the second conductive component 32b abuts against the second pin 512. When retracted into the second receiving cavity 23, the first pin 511 and the second pin 512 are driven by the mounting base 52 to move towards the first housing 10, such that the first abutting component is disconnected from the first pin 511 and the second abutting component is disconnected from the second pin 512.
The ejector component 15 (such as the push-pull rod 151) is configured to push the second connector 50 (such as the mounting base 52) in response to the relative rotation between the first housing 10 and the second housing 20, such that the second connector 50 (such as the first pin 511 and the second pin 512) is slid in the direction of the extension of the slide-ways 521 to be extended out of the second receiving cavity 23. In response to the second connector 50 (such as the first pin 511 and the second pin 512) being extended out of the second receiving cavity 23, the first pin 511 abuts against the abutting component 323 of the electronic assembly 30 (such as the first conductive component 32a), and the second pin 512 abuts against the second abutting component 323 of the electronic assembly 30 (such as the second conductive component 32b).
The ejector component 15 (such as the push-pull rod 151) is configured to pull the second connector 50 (such as the mounting base 52) in response to the relative rotation between the first housing 10 and the second housing 20, such that the second connector 50 (such as the first pin 511 and the second pin 512) is slid in the direction of the extension of the slide-ways 521 and retracts into the second receiving cavity 23. In response to the second connector 50 (such as the first pin 511 and the second pin 512) being retracted into the second receiving cavity 23, the first pin 511 is disconnected from the first abutting component 323 of the electronic assembly 30 (such as the first conductive component 32a), and the second pin 512 is disconnected from the second abutting component 323 of the electronic assembly 30 (such as the second conductive component 32b).
As shown in FIG. 1, in response to the relative rotation between the first housing 10 and the second housing 20, an outer surface of the first housing 10 is substantially flush with an outer surface of the second housing 20 all the time. That is, no corner angle exists between contacting portions of the first housing 10 and the second housing 20, which improves appearance performance. A rotating angle required in the relative rotation between the first housing 10 and the second housing 20 to rotate the second connector 50 outside or inside for storage is not limited herein.
In an embodiment, the first housing 10 is able to be rotated by an angle of 360° relative to the second housing 20, to achieve a first state in which the second connector 50 is completely received in the second receiving cavity 23 to a second state in which the second connector 50 is extended out of the second receiving cavity 23 to the maximum extent. Of course, the rotating angle may also have other values, such as 45°, or 90°, which may be set according to the actual needs and not repeated herein.
As shown in FIG. 26, FIG. 26 is a structural schematic view of the power adapter 100 in FIG. 1 having another appearance. Both the first housing 10 and the second housing 20 in this power adapter 100 have columnar structures with square cross-sections. Of course, both the first housing 10 and the second housing 20 may also have the columnar structures with polygonal cross-sections. In response to the relative rotation between the first housing 10 and the second housing 20, the corner angle is generated between the contacting portions of the first housing 10 and the second housing 20, which affects the appearance performance. In response to the second connector 50 being in the first state in which the second connector 50 is completely received in the second receiving cavity 23, the corner angle is generated between the contacting portions of the first housing 10 and the second housing 20, which affects the storage. In response to the second connector 50 being in the second state in which the second connector 50 is extended out of the second receiving cavity 23 to the maximum extent, the corner angle is generated between the contacting portions of the first housing 10 and the second housing 20, which affects usage.
Therefore, it is necessary to limit the rotating angle required in the relative rotation between the first housing 10 and the second housing 20 to rotate the second connector 50 outside or inside for storage, to ensure that the outer surface of the first housing 10 may be substantially flush with the outer surface of the second housing 20 in both a storage state and a usage state, and no corner angle exists between the contacting portions of the first housing 10 and the second housing 20. In this way, the appearance performance of the power adapter 100 may be improved. For example, the rotating angle may be set to be an integer multiple of 90°.
As shown in FIG. 26, a first receiving slot 123 is defined at a side of the first side plate 12 of the first housing 10 facing the second housing 20. A first magnetic component 124 is arranged in the first receiving slot 123. A second receiving slot 224 is defined at a side of the second side plate 22 of the second housing 20 facing the first housing 10. A second magnetic component 225 is arranged in the second receiving slot 224. The first magnetic component 124 and the second magnetic component 225 are configured to have opposite poles which are attractable. The first housing 10 may be controlled to be rotated an integer multiple of 360° relative to the second housing 20, such that the second connector 50 may be slid from the first state in which the second connector 50 is completely received in the second receiving cavity 23 to the second state in which the second connector 50 is extended out of the second receiving cavity 23 to the maximum extent.
In response to the second connector 50 being in the first state in which the second connector 50 is completely received in the second receiving cavity 23, the first magnetic component 124 directly or right faces the second magnetic component 225, and the first magnetic component 124 and the second magnetic component 225 are attracted by each other. In this way, it is easy for the user to perceive that the second housing 10 is rotated to a first right position relative to the second housing 20, where the outer surface of the first housing 10 is substantially flush with the outer surface of the second housing 20 and no corner angle exists between the contacting portions of the first housing 10 and the second housing 20. In this way, it is convenient for the storage.
In response to the second connector 50 being slid to the second state where the second connector 50 is extended out of the second receiving cavity 23 to the maximum extent, the first magnetic component 124 directly or right faces the second magnetic component 225, and the first magnetic component 124 and the second magnetic component 225 are attracted by each other. It is easy for the user to perceive that the second housing 10 is rotated to a second right position relative to the second housing 20, where the outer surface of the second housing 20 is substantially flush with the outer surface of the second housing 20 and no corner angle exists between the contacting portions of the first housing 10 and the second housing 20. In this way, it is convenient for the usage.
It can be understood that both the number of the first magnetic members 124 and the number of the second magnetic members 225 may be multiple. The first magnetic members 124 and the second magnetic members 225 may be evenly and circumferentially distributed around the axis along which the first housing 10 is rotated relative to the second housing 20. For example, the number of the first magnetic components 124 is two. In response to the second magnetic component 225 directly or right facing and being attracted by any one of the two magnetic components 124, the outer surface of the first housing 10 is substantially flush with the outer surface of the second housing 20, and no corner angle exists between the contacting portions of the first housing 10 and the second housing 20. In response to the second magnetic component 225 directly or right facing and being attracted by one of the two magnetic components 124, the second connector 50 is in the first state in which the whole of the second connector 50 is received in the second receiving cavity 23. In response to the second magnetic component 225 directly or right facing towards and being attracted by the other one of the two magnetic components 124, the second connector 50 is in the second state in which the second connector 50 is extended out of the second receiving cavity 23 to the maximum extent.
Understandably, both the first magnetic component 124 and the second magnetic component 225 may be magnets. The first magnetic component 124 and the second magnetic component 225 are configured to indicate right positions and alignment, such that poor appearance performance may be avoided, and user experience may be improved. In some embodiments with the battery, both the first magnetic component 124 and the second magnetic component may be electromagnets.
According to the above embodiments of the present disclosure, the first housing 10 is configured to be concentrically rotated relative to the second housing 20. The ejector mechanism 60 is adjusted through the relative rotation between the first housing 10 and the second housing 20 to cause the second connector 50 to displace, such that the second connector 50 is at least partially located outside the accommodating cavity 101 for normal usage or the second connector 50 is located in the accommodating cavity 101 for the storage. The technical solution of the present disclosure is simple, reliable, and may achieve unscrewing, locking, and collecting of the power adapter. In this way, a size of a product may be reduced, a misoperation may be avoided, and the user experience may be improved.
The above descriptions above are only some embodiments of the present disclosure. The scope of the present disclosure is not limited by the above descriptions. Any equivalent structure transformation or equivalent process transformation of the present disclosure made based on contents of the specification and the drawings of the present disclosure, or direct or indirect applications in other related technical fields, are all similarly included within the scope of the present disclosure.
