Description

Technical Field

[0001] The present invention relates to a charging and data adapter, and in particular to a multifunctional charging and data adapter with both charging function and all-in-one data transfer integration. Background Art

[0002] When a user wants to connect an electronic device such as a mobile phone, tablet computer, or laptop computer to a television, projector, or other electronic device, an adapter (also often called a hub) is often required to bridge the signal of the electronic device to another electronic device.

[0003] The general adapters are single-function and can only handle one or two adapter functions, such as USB to HDMI, USB to memory card or USB to Ethernet interface, and may not support high-speed data transmission. If multiple functions are concentrated in one adapter, the adapter will be too large and bulky.

[0004] In addition, general adapters do not have a charging function. Users often need to prepare or carry a charger plug and more than one data adapter connector to charge the mobile electronic device and transfer file data or multimedia data to other electronic devices. Summary of the invention

[0005] However, users need to carry a charger plug and more than one data adapter connector at the same time. In addition to the inconvenience and confusion caused by carrying multiple chargers and adapters, the charger plug and the adapter connector need to occupy two storage positions, so that a lot of volume is required to store and carry the charger plug and the adapter connector.

[0006] In addition, the single function of the charger plug and the data adapter makes it impossible for the user to conveniently use the electronic device if the user only remembers to carry one of them. For example, when the user only carries the charger plug, data cannot be transferred; when the user only carries the data adapter, the electronic device cannot be charged effectively and quickly.

[0007] Furthermore, if the charger plug and the data adapter are simply integrated and combined into one device, the adapter with charging function is too large, which is also an important factor that affects the convenience of users.

[0008] On the other hand, in order to meet the demand for high-speed data transmission between different ports, existing all-in-one data adapters all use a single circuit board as a means of data transmission between different ports. However, when a single circuit board has different data ports, it must occupy a large space to accommodate different data ports, making it impossible to reduce the size of the adapter.

[0009] Therefore, it is very important to provide a multifunctional charging and data adapter that can simultaneously charge and transmit data at high speed between multiple different types of data ports, while minimizing the size to increase the convenience of carrying and storage for users.

[0060] In order to explain the technical content of the present invention in detail, the following is further described in conjunction with the embodiments and the accompanying drawings. It should be noted that in the content of this article, terms such as "first", "second" and "third" are used to distinguish the differences between components, rather than to limit the components themselves or to indicate a specific order of components. In addition, in the content of this article, when a specific number is not specifically specified, the article "a" refers to one component or more than one component.

[0061] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments and the accompanying drawings. The description is as follows.

[0062] Figure 1A A schematic diagram of a charger and a data adapter in the prior art; Figure 1B The figure is a schematic diagram of a circuit board and a connection port inside a data adapter in the prior art.

[0063] like Figure 1A As shown, the charger 1 of the existing electronic devices such as mobile phones, tablets, laptops, wearable devices, multimedia devices, smart home appliances, etc. does not have the transmission function of the data adapter 2 to exchange data of different data connection ports 6 such as USB, HDMI, SD card, Ethernet. Similarly, the existing data adapter 2 does not have a charger 1 with a plug and a transformer that can be directly plugged into a power socket, so it does not have the function of charging the electronic device. Even if the data adapter 2 has a connector that can be re-inserted into the power supply line to power the electronic device, it still needs an additional charger plug and transformer to obtain power supply.

[0064] Figure 1B Schematically shown as Figure 1A, a schematic diagram of the internal circuit board 5 and the data connection hole 6 of the data adapter 2 is shown in the figure. In order to meet the requirements of high-speed data transmission between different types of ports, existing all-in-one data adapters 2, such as adapters with USB, HDMI, SD card, and Ethernet data transfer transmission functions, use a single circuit board 5, such as a printed circuit board (PCB), as a path for data transmission between different types of ports, and set processing modules and integrated circuits (ICs) corresponding to different types of data connection holes on this single circuit board 5. However, while the single circuit board 5 has different types of data connection holes 6, the single circuit board 5 must occupy a large plane space to accommodate different types of data connection holes 6, such as Figure 1B As shown, the single circuit board 5 needs to arrange its connection holes in sequence on its edge, so that the volume of the existing all-in-one data adapter 2 cannot be reduced.

[0065] The present invention provides a multifunctional charging and data adapter, which can provide charging function and data transfer function at the same time and has a better internal space configuration to reduce the volume of the whole multifunctional charging and data adapter.

[0066] Figure 2 It is a three-dimensional schematic diagram of a multifunctional charging and data adapter in one embodiment of the present invention. The present invention provides a multifunctional charging and data adapter 10, which is suitable for charging and data transfer of electronic devices. The electronic devices include but are not limited to mobile phones, tablets, laptops, game consoles, handheld game consoles, wearable devices, multimedia devices, smart appliances, workstations, servers, Internet devices and other electronic devices suitable for charging or transmitting data. The data transfer includes but is not limited to USB type-C, USB type-A, HDMI, Ethernet, SD card, micro SD card and other data transmission interfaces and physical connection holes. Figure 2 As shown, the multifunctional charging and data adapter 10 includes a housing 101 and a plurality of data transmission connection holes 160 to provide data transmission between different connection hole interfaces, for example, supporting the transmission of multimedia data of a mobile phone to a TV for playback through the data transmission connection hole 160 of the multifunctional charging and data adapter 10. In one embodiment, the plurality of data transmission connection holes 160 include USB type-C, USB type-A, HDMI, Ethernet (e.g., RJ45 connector), SD card, and micro SD card.

[0067] Figure 3The multifunctional charging and data adapter 10 further includes a first circuit board 110 , a second circuit board 120 , a charging module 140 , a charging plug 141 , a flexible circuit board 150 , and a plurality of data transmission connection holes 160 .

[0068] The first circuit board 110 is disposed in the housing 101 . The first circuit board 110 is provided with at least one of a plurality of data transmission connection holes 160 .

[0069] The second circuit board 120 is disposed in the housing 101 and adjacent to the first circuit board 110. The second circuit board 120 is provided with at least another one of the plurality of data transmission connection holes 160. The charging plug 141 is disposed in the housing 101. In one embodiment, the charging plug 141 can be rotatably stored or ejected.

[0070] The charging module 140 is electrically connected to the charging plug 141 and the first circuit board 110 or the second circuit board 120. The charging module 140 is configured to receive power from the outside through the charging plug 141, such as the mains power from the power socket, and transmit it to one or more of the multiple data transmission connection holes 160 through the first circuit board 110 or the second circuit board 120, such as supplying power to the interface connection holes such as USB type-C, USB type-A, and HDMI. In one embodiment of the present invention, the charging module 140 includes a transformer, an electromagnetic interference filter unit (EMI filter), a capacitor, a charging control IC, etc. In one embodiment of the present invention, the charging module 140 supports high-power fast charging of PD (Power Delivery), such as supporting PD 65W charging, and can provide data transmission while charging.

[0071] The flexible circuit board 150 is configured to be electrically connected between circuit boards. The flexible circuit board 150 may be one or more. In one embodiment, the flexible circuit board 150 includes a first flexible circuit board 151 and a second flexible circuit board 152 to electrically connect different circuit boards or electronic components. Figure 3As shown, the first flexible circuit board 151 is configured to be electrically connected between the first circuit board 110 and the second circuit board 120 to provide a telecommunication transmission path between the first circuit board 110 and the second circuit board 120, wherein the second flexible circuit board 152 is configured to be electrically connected between the second circuit board 120 and the third circuit board 130 to provide a telecommunication transmission path between the second circuit board 120 and the third circuit board 130. In order to provide high-speed signal transmission between the first circuit board 110 and the second circuit board 120, since the first circuit board 110 and the second circuit board 120 cannot be directly connected to each other by gold-plated connecting parts (also called gold fingers) to transmit high-speed signals, nor can they be directly used for board-to-board signal transmission by welding, the present invention provides a method of using a flexible printed circuit 150 (FPC) for high-speed signal transmission, such as USB 3.0 high-speed signal transmission, to achieve high-speed signal transmission between circuit boards in a narrow space by utilizing the characteristics of the flexible printed circuit 150, which is soft, thin, and can be bent and folded at will, for example, the first flexible printed circuit 151 is used to achieve high-speed signal transmission between the first circuit board 110 and the second circuit board 120. In one embodiment of the present invention, the flexible printed circuit 150 adopts a double-layer board structure to better control impedance and reduce impedance and signal reflection between contacts. In one embodiment of the present invention, the flexible printed circuit 150 adopts PI (Polyimide) as a substrate, and adjusts and reduces the impedance between its contacts in a structurally adaptive manner. In one embodiment of the present invention, the flexible circuit board 150 includes a shielding structure. By adding shielding on the upper and lower surfaces of the flexible circuit board 150, interference sources in the external environment are isolated to improve the stability of the signal. The shielding is, for example, a metal copper foil layer is set on the upper and lower surfaces of the flexible circuit board 150. In this way, through the setting of the flexible circuit board 150 (for example, the first flexible circuit board 151), in addition to providing high-speed signal transmission between the first circuit board 110 and the second circuit board 120, signal transmission and configuration flexibility in a narrow and crowded space are also provided, and electromagnetic interference (EMI) and impedance problems when directly connecting the boards are solved. It should be noted that the flexible circuit board 150 and the first flexible circuit board 151 shown in the figure are exemplary configuration forms and are not limited thereto.

[0072] Figure 4Schematic diagram of the internal configuration of the multifunctional charging and data adapter from another perspective in one embodiment of the present invention. In one embodiment of the present invention, the multifunctional charging and data adapter 10 includes a first circuit board 110, a second circuit board 120, a third circuit board 130, a charging module 140, a charging plug 141, a flexible circuit board 150, and a plurality of data transmission connection holes 160. The data transmission connection holes 160 are, for example, USB type-C, USB type-A, HDMI, RJ45, SD card, micro SD card, etc. interface connection holes. In one embodiment of the present invention, Figure 4 As shown, the third circuit board 130 is disposed in a housing (not shown) and adjacent to the first circuit board 110 and the second circuit board 120. The third circuit board 130 is configured to be electrically connected to at least another one of the plurality of data transmission connection holes 160, that is, the first circuit board 110, the second circuit board 120 and the third circuit board 130 are respectively provided with different data transmission connection holes 160. Figure 4 As shown, the second circuit board 120 and the third circuit board 130 are arranged in parallel, and the second circuit board 120 and the third circuit board 130 are arranged perpendicular to the first circuit board 110, that is, the second circuit board 120 and the third circuit board 130 are arranged perpendicular to the first circuit board 110. In one embodiment, the first circuit board 110 and the second circuit board 120 can also be arranged parallel to each other. Thereby, several circuit boards can be stacked or combined in a suitable form perpendicular or parallel to each other, so that the space arrangement and arrangement between the circuit boards (such as 110 to 130) and the several data transmission connection holes 160 is the most compact minimum volume. In one embodiment of the present invention, Figure 4 As shown, the first circuit board 110 is a main circuit board with a size similar to that of a surface of the housing (not shown). The first circuit board 110 is provided with a charging module 140 and a charging plug 141 that can be rotated and scaled and exposed to the housing. In one embodiment of the present invention, the charging module 140 may include, for example, a transformer 142, a capacitor 143, an electromagnetic interference filter unit 144, a charging control IC and other related electronic components, and an embodiment of its spatial configuration may be as shown in FIG. Figure 4As an example. In one embodiment of the present invention, the aforementioned charging module 140 is disposed on the first surface of the first circuit board 110, and the first surface of the first circuit board is further provided with a second circuit board 120 and a third circuit board 130. In this embodiment, the data transmission connection hole 160 provided on the second circuit board 120 is, for example, a connector interface of USB type-C, USB type-A and HDMI. In order to minimize the overall volume, the connector interfaces of USB type-C, USB type-A and HDMI are vertically disposed on the second circuit board 120, and the second circuit board 120 is vertically disposed on the first circuit board 110, so that the height of the overall multi-functional charging and data adapter 10 can be minimized to a width close to the above-mentioned USB type-C, USB type-A and HDMI connection holes, and the first circuit board 110 can still properly utilize the space between these connection holes to achieve maximum efficiency in space utilization. In this embodiment, the data transmission connection hole 160 provided on the third circuit board 130 is, for example, an RJ45 connector interface for Ethernet communication. Since the RJ45 connection hole needs to have a physical space to accommodate the RJ45 connector, the RJ45 connection hole is disposed on a side close to the charging module 140, so that the components of the charging module 140 that can adjust the position flexibly can provide space for the RJ45 connection hole without occupying the use space of other data transmission connection holes 160, and thus the second circuit board 120 and the third circuit board 130 can be as close as possible to reduce the volume of the overall multifunctional charging and data adapter 10. The second circuit board 120 and the third circuit board 130 are arranged in parallel and disposed in another area of ​​the first circuit board 110 relative to the charging module 140, and the second circuit board 120 and the third circuit board 130 are disposed perpendicular to the first circuit board 110. Thus, the second circuit board 120 with the data transmission connection holes 160 configured outward, such as USB type-C, USB type-A and HDMI connection holes, can be as close as possible to the third circuit board 130 with the data transmission connection holes 160, such as RJ45 connection holes for Ethernet communication, configured toward the charging module 140, so as to minimize the volume occupied by all connection holes and necessary circuits, maximize the space utilization, minimize the useless space, and reduce the volume of the whole multifunctional charging and data adapter 10 as much as possible to the volume defined by the interface connection holes and necessary components (such as transformer 142). It should be noted that the spatial position between the circuit boards is not limited to this example. Any variation in which the circuit boards are arranged vertically or parallel to each other to reduce the circuit board area, reduce the volume of protruding components, and meet the purpose of the actual interface connection holes, all belong to the scope of the concept of the present invention.

[0073] Next, the connection method and spatial arrangement of the first flexible circuit board 151 and the second flexible circuit board 152 included in the flexible circuit board 150 are described. Figure 5 FIG. 1 is a schematic diagram of the configuration of a multifunctional charging and data adapter and its flexible circuit board 150 in one embodiment of the present invention, and a partial enlarged schematic diagram of the same in different viewing angles. Figure 5 As shown, the first circuit board 110 includes a first flexible circuit connection hole 111, and the second circuit board 120 includes a second flexible circuit connection hole 121. It should be noted that the number of the flexible circuit connection holes, such as the first flexible circuit connection hole 111 and the second flexible circuit connection hole 121, is not limited to one. The same circuit board may have more than one flexible circuit connection hole to connect with multiple circuit boards and the flexible circuit board 150. In one embodiment, the second flexible circuit connection hole 121 includes second flexible circuit connection holes 121a and 121b respectively arranged on both sides of the second circuit board 120. The first flexible circuit board 151 is configured to be connected between the first flexible circuit connection hole 111 and the second flexible circuit connection hole 121a, and wherein the first flexible circuit connection hole 111 and the second flexible circuit connection hole 121a are arranged adjacent to each other. In this way, the signal transmission distance of the first flexible circuit board 151 can be shortened to reduce the difficulty of controlling its impedance and reduce the interference or influence of signals in the environment, and reduce the loss during signal transmission. In addition, the assembly complexity of the flexible circuit board can be reduced and mass production can be easily achieved. In one embodiment of the present invention, the third circuit board 130 includes a third flexible circuit connection hole 131, for example Figure 5As shown in the example, the third flexible circuit connection hole 131 and the second flexible circuit connection hole 121b are arranged in parallel in the same direction to reduce the hard bending and twisting of the second flexible circuit board 152 that electrically connects the two, further reducing the required space and further reducing signal loss and interference. In one embodiment of the present invention, the first flexible circuit connection hole 111 and the second flexible circuit connection hole 121 (including 121a and 121b) are arranged adjacent to the third flexible circuit connection hole 131, so that at least one flexible circuit board 150 is configured to be connected between the first flexible circuit connection hole 111, the second flexible circuit connection hole 121 and the third flexible circuit connection hole 131, thereby increasing its application flexibility and possibility of being connected between different circuit boards. In addition, in this embodiment, by respectively arranging the second flexible circuit connection holes 121 of the second circuit board 120 on both sides of the same position of the edge of the second circuit board, i.e., the positions shown as 121a and 121b, the distance between the first flexible circuit connection hole 111, the second flexible circuit connection hole 121 (including 121a and 121b) and the third flexible circuit connection hole 131 can be minimized, and at the same time, there is no need to increase the size or width of the second circuit board 120 to accommodate the second flexible circuit connection holes 121a and 121b on the same side. Furthermore, the second flexible circuit board 152 is connected through the second flexible circuit connection hole 121b on one side adjacent to the third circuit board 130, and the first flexible circuit board 151 is connected through the second flexible circuit connection hole 121a on the other side away from the third circuit board 130, so as to avoid the paths of the second flexible circuit board 152 and the first flexible circuit board 151 being intertwined. Furthermore, a portion 155 of the first flexible circuit board 151 has a turning extension portion 156, and the turning extension portion 156 extends and connects to the first flexible circuit connection hole 111 of the first circuit board 110. In one embodiment of the present invention, the portion 155 having the turning extension portion 156 is located in a segment that is perpendicular to the second circuit board 120 and the third circuit board 130, for example Figure 5 The bent portion 155 of the first flexible circuit board 151 shown in the figure has a turning extension portion 156 extending in the direction of the first circuit board 110 and connected to the first flexible circuit connection hole 111 that is aligned and adapted. In this way, the length and number of bending times of the flexible circuit board 150 when connecting between multiple circuit boards (such as the first circuit board 110 to the third circuit board 130) can be reduced, and the connection of high-speed signal transmission of multiple circuit boards can be achieved with the shortest path and the smallest occupied space, and it can be adapted to the flexible circuit connection holes with different connection hole angles. It should be noted that in order to meet the needs of the minimum path required for the flexible circuit board in a narrow space and the design of the flexible circuit connection hole angle, the turning extension portion is not limited to being set on the first flexible circuit board, and other flexible circuit boards may also have the design of the turning extension portion.

[0074] Figure 6This is a schematic diagram of the internal configuration of the multifunctional charging and data adapter from another perspective in one embodiment of the present invention, and the second side (i.e., the back side) of the first circuit board 110 is used as an example. In one embodiment of the present invention, the first circuit board 110 also includes at least one memory card slot 170, and the memory card slot 170 can be, for example, a slot corresponding to an SD card, a slot corresponding to a micro SD card, etc., wherein the memory card slot 170 can be one of the aforementioned multiple data transmission connection holes 160. The memory card slot 170 is specifically used as an example here because its spatial shape is relatively flat, so it is used as an example of the embodiment. Among them, the second circuit board 120 and the charging module 140 are arranged on the first side of the first circuit board 110, and the memory card slot 170 is arranged on the second side of the first circuit board 110 relative to the first side, for example, the second circuit board 120 and the charging module 140 are arranged on the front side of the first circuit board 110, and the memory card slot 170 is arranged on the back side of the first circuit board 110. Thus, since the three-dimensional shape of the memory card slot 170 is wide and flat, if the memory card slot 170 is set on a side having many electronic components such as the second circuit board 120 and the charging module 140, the arrangement space of the electronic components will be squeezed, and the required volume will increase.

[0076] Through the electronic circuit design and three-dimensional space configuration between multiple circuit boards, the multifunctional charging and data adapter provided by the present invention can not only simultaneously achieve the functions of charging and data transmission and conversion between different interface connection holes, but also can more effectively utilize space, that is, greatly reduce the space required to achieve the above functions.

[0077] Through the multifunctional charging and data adapter of the present invention, only one charging adapter is needed to provide charging and data transmission conversion between different interface connection holes at the same time, and through the parallel or perpendicular spatial arrangement of the circuit boards, and the flexible circuit board as the high-speed data transmission between the circuit boards, the useless space waste can be minimized, and the volume of the whole multifunctional charging and data adapter can be minimized to be close to the volume of the necessary electronic components contained therein, and the charging and all-in-one data conversion functions are achieved in a single adapter.

In one embodiment, through the aforementioned space utilization method and high-speed signal transmission method between circuit boards of the present invention, the aforementioned eight-in-one multifunctional charging and data adapter can be achieved in a size of approximately 69 mm in length, 68 mm in width, and 33 mm in height, which is similar in size to data adapters on the market that can only provide three-in-one functions.
