Description

Technical Field

[0001] This invention relates to the technical field of power supply devices, and more particularly to a power supply device with storage function. Background Technology

[0002] It is known that mobile electronic products such as smartphones, tablets, laptops, and smartwatches have become indispensable for people's work, life, and entertainment. It is also known that, in order to meet the trend of lighter and thinner mobile electronic products, lithium battery packs are becoming increasingly thinner, thus limiting their capacity. Therefore, users must frequently connect their mobile electronic products (such as smartphones) to power supply devices such as power banks or chargers.

[0003] It is also known that some users are replacing laptops or desktop computers with smartphones or tablets. For example, instead of traditionally handwritten notes, university students now use styluses to operate tablets (or smartphones) to digitize their notes during class. However, due to the limited built-in memory of tablets, typically 64GB, 128GB, or 256GB, users must connect an external storage device to their tablet to store electronic notes, audio-visual data, or other data.

[0004] Based on practical experience, due to the limited capacity of lithium battery packs, the following situations often occur: (1) The lithium battery pack suddenly runs out while the user is using a stylus to operate the tablet computer to digitize notes, forcing the user to remove the external storage device and connect the tablet computer to a power source; at this time, the digitized notes can no longer be stored on the external storage device; or (2) The lithium battery pack suddenly runs out while the user is playing audio and video data on the tablet computer (or smartphone), causing the user to have to remove the external storage device and connect the tablet computer to the power supply; at this time, the tablet computer can no longer play audio and video data.

[0005] In summary, existing power supply devices (such as chargers and portable power banks) should be redesigned to include data storage functionality, thereby addressing the aforementioned shortcomings of the prior art. Therefore, the inventor of this utility model has diligently researched and invented this invention, and has finally completed the development of a power supply device with storage functionality.

[0022] First Embodiment Figure 1A , Figure 1B These are the first and second perspective views of a power supply device with storage function according to this utility model. Figure 2 This is a first exploded perspective view of the power supply device with storage function according to this utility model. Furthermore, Figure 3 This is a first application view of the power supply device with storage function according to this utility model, and Figure 4 This is a first block diagram of the power supply device with storage function according to this utility model. Figure 1A , Figure 1B , Figure 2 , Figure 3 ,and Figure 4 As shown, in the first embodiment, the power supply device 1 with storage function of this utility model is a charger, and mainly includes: a housing 10, an electrical connection unit 11, a power supply module 12, and N electrical connectors (e.g., ...). Figure 1B , Figure 4 The diagram illustrates a first electrical connector 1E1 and a control module 13, wherein the housing 10 includes a base 10B and a cover 10T. In feasible embodiments, N is a positive integer of at least 1, and the first electrical connector 1E1 may be, but is not limited to, a USB Type-A connector, a USB Type-C connector, or a Thunderbolt connector.

[0023] Specifically, the base 10B has multiple sides, and these multiple sides have a total of N openings. The N electrical connectors are disposed inside the housing 10 to couple with the power supply module 12, and correspondingly protrude from the housing 10 through the N openings. For example, Figure 1A , Figure 1B and Figure 2The plurality of sides are illustrated exemplaryly, including a first side 10S1, a second side 10S2, a third side 10S3, and a fourth side 10S4. The electrical connection unit 11 is connected to the first side 10S1, and the third side 10S3 has a first opening 10H1. More specifically, the electrical connection unit 11 has a first connection side 111 and a second connection side 112. The first connection side 111 extends into the interior of the receiving body 10, and the second connection side 112 is used for electrical connection to a power source.

[0024] In feasible embodiments, the electrical connection unit 11 may be, but is not limited to, a power plug, a USB Type-C electrical connector, a USB Type-A electrical connector, a power socket, or a power cord. For example, Figure 1A , Figure 1B and Figure 2 The electrical connection unit 11 is illustrated as a power plug comprising K metal pins, where K is 2 or 3. It should be noted that "first," "second," "third," and "fourth" do not refer to a clockwise or counterclockwise order, but rather are used to distinguish the first side 10S1, the second side 10S2, the third side 10S3, and the fourth side 10S4 from the four different sides of the housing 10.

[0025] To explain in more detail, the power supply module 12 is disposed inside the housing 10 and is electrically connected to the second connection side 112. For example... Figure 2 and Figure 4 As shown, the power supply module 12 includes a power conversion unit 121, at least one DC-DC conversion chip 122, a first switching unit 123, and a power management chip 124. The power conversion unit 121 is coupled to the power supply via the electrical connection unit 11 and is used to convert the power supply into a first power supply. Furthermore, the at least one DC-DC conversion chip 122 is coupled to the power conversion unit 121 and is used to convert the first power supply into a second power supply (e.g., 3.3V) and / or a third power supply (e.g., 5.0V, 9.0V), supplying the second power supply to the control module 13, and supplying the second or third power supply to the first electrical connector 1E1 via the first switching unit 123. For example, if the first electrical connector 1E1 is a USB 2.0 Type-A connector, the second power supply supplies power to the control module 13 and the first electrical connector 1E1. For example, if the first electrical connector 1E1 is a USB 3.0 Type-A connector or a USB Type-C connector, the second power supply supplies power to the control module 13, and the third power supply supplies power to the first electrical connector 1E1.

[0026] On the other hand, the control module 13 is disposed inside the housing 10 to couple the power supply module 12 to the N electrical connectors, and includes at least one memory 13M storing an instruction set and a microprocessor 13P, wherein the microprocessor 13P is coupled to the first electrical connector 1E1 and the memory 13M.

[0027] like Figure 2 and Figure 4 As shown, the first switching unit 123 is coupled between the DC-DC converter chip 122 and the first electrical connector 1E1, and the power management chip 124 is coupled between the first switching unit 123, the microprocessor 13P, and the first electrical connector 1E1. In the first embodiment, the power management chip 124 is configured to perform: After a first electronic device 2 is connected to the first electrical connector 1E1, it receives a first battery status information containing a first remaining power level from the first electronic device 2 through the first electrical connector 1E1. When the remaining power level is lower than a predetermined low power threshold, the first switching unit 123 is enabled to perform a first switching operation to establish an electrical connection between the first electrical connector 1E1 and the DC-DC converter chip 122, thereby allowing the second power supply or the third power supply to be transmitted to the first electronic device 2 through the first electrical connector 1E1; and When the first remaining power is higher than a predetermined high power threshold, the first switching unit 123 is enabled to perform a second switching operation to disconnect the electrical connection between the first electrical connector 1E1 and the DC-DC converter chip 122, thereby stopping the power supply to the first electronic device 2.

[0028] To reiterate, the control module 13 includes at least one memory 13M and a microprocessor 13P coupled to the first electrical connector 1E1 and the memory 13M. The memory 13M stores an instruction set, and the microprocessor 13P executes the instruction set to be configured to perform the following: when the first electronic device 2 is connected to the first electrical connector 1E1, receiving a first data access command and / or a first stored data from the first electronic device 2 through the first electrical connector 1E1, thereby accessing the at least one memory 13M according to the first data access command and / or the first stored data.

[0029] In short, the power supply device 1 (e.g., a charger) of this invention can simultaneously store data transmitted by the first electronic device 2 (e.g., a smartphone, tablet computer, or laptop computer) and can also transmit data to the first electronic device 2. This design gives the power supply device 1 of this invention the following practical advantages: (1) When a user operates or uses their smartphone or tablet computer (i.e., the first electronic device 2), they can store or back up some data (such as audio and video data) in the 13M memory of the power supply device 1 of this utility model, without having to specifically remove the power supply device 1 of this utility model and connect an external storage device; and (2) When a user plays audio-visual data stored in the power supply device 1 of this utility model while using his or her smartphone or tablet computer (i.e., the first electronic device 2), if the lithium battery power is lower than a predetermined threshold, the power supply device 1 of this utility model will automatically charge the user's smartphone or tablet computer.

[0030] Second Embodiment Figure 5A , Figure 5B The third and fourth perspective views are of the power supply device with storage function of this utility model, and Figure 6 This is a second exploded perspective view of the power supply device with storage function according to this utility model. Furthermore, Figure 7 This is a second application view of the power supply device with storage function according to this utility model, and Figure 8 This is a second block diagram of the power supply device with storage function according to this utility model. Figure 5A , Figure 5B , Figure 6 , Figure 7 ,and Figure 8 As shown, in the second embodiment, the power supply device 1 with storage function of this utility model is a portable power bank charger, and also includes: a housing 10, an electrical connection unit 11, a power supply module 12, and N electrical connectors (e.g., Figure 5B , Figure 6 A first electrical connector 1E1 and a control module 13 are shown.

[0031] Similarly, Figure 5A , Figure 5B and Figure 6 The accommodating body 10 is illustrated exemplary, having multiple sides, including a first side 10S1, a second side 10S2, a third side 10S3, and a fourth side 10S4. An electrical connection unit 11 is connected to the first side 10S1, and the third side 10S3 and the first side 10S1 have a first opening 10H1 and an exposure hole 10H. In feasible embodiments, the electrical connection unit 11 may be, but is not limited to, a power plug, a USB Type-C electrical connector, a USB Type-A electrical connector, a power socket, or a power cord. For example, Figure 5A and Figure 6The electrical connection unit 11 is illustrated as an electrical connector, which exposes the receiving body 10 through the exposed hole 10H, thereby electrically connecting to a power source.

[0032] like Figure 6 and Figure 8 As shown, the power supply module 12 is disposed inside the housing 10 and electrically connected to the electrical connection unit 11. It is worth noting that in the second embodiment, the power supply module 12 includes a lithium battery pack 120, at least one DC-DC converter chip 122, a first switching unit 123, and a power management chip 124. The lithium battery pack 120 is coupled to the N electrical connectors and is used to provide a first power supply. Furthermore, the at least one DC-DC converter chip 122 is coupled to the lithium battery pack 120 and is used to convert the first power supply into a second power supply (e.g., 3.3V) and / or a third power supply (e.g., 5.0V, 9.0V), and supplies the second power supply to the control module 13. The first switching unit 123 supplies the second or third power supply to the first electrical connector 1E1. For example, if the first electrical connector 1E1 is a USB 2.0 Type-A connector, the second power supply supplies power to the control module 13 and the first electrical connector 1E1. For example, if the first electrical connector 1E1 is a USB 3.0 Type-A connector or a USB Type-C connector, the second power supply supplies power to the control module 13, and the third power supply supplies power to the first electrical connector 1E1.

[0033] On the other hand, the control module 13 is disposed inside the housing 10 to couple the power supply module 12 to the N electrical connectors, and includes at least one memory 13M storing an instruction set and a microprocessor 13P, wherein the microprocessor 13P is coupled to the first electrical connector 1E1 and the memory 13M.

[0034] like Figure 6 and Figure 8 As shown, the power management chip 124 is coupled to the first switching unit 123, the microprocessor 13P, and the first electrical connector 1E1, and is configured to perform: After a first electronic device 2 is connected to the first electrical connector 1E1, it receives a first battery status information containing a first remaining power level from the first electronic device 2 through the first electrical connector 1E1. When the remaining power level is lower than a predetermined low power threshold, the first switching unit 123 is enabled to perform a first switching operation to establish an electrical connection between the first electrical connector 1E1 and the DC-DC converter chip 122, thereby allowing the second power supply or the third power supply to be transmitted to the first electronic device 2 through the first electrical connector 1E1; and When the first remaining power is higher than a predetermined high power threshold, the first switching unit 123 is enabled to perform a second switching operation to disconnect the electrical connection between the first electrical connector 1E1 and the DC-DC converter chip 122, thereby stopping the power supply to the first electronic device 2.

[0035] To reiterate, the control module 13 includes at least one memory 13M and a microprocessor 13P coupled to the first electrical connector 1E1 and the memory 13M. The memory 13M stores an instruction set, and the microprocessor 13P executes the instruction set to be configured to perform the following: when the first electronic device 2 is connected to the first electrical connector 1E1, receiving a first data access command and / or a first stored data from the first electronic device 2 through the first electrical connector 1E1, thereby accessing the at least one memory 13M according to the first data access command and / or the first stored data.

[0036] In simple terms, the power supply device 1 (e.g., a power bank) of this utility model can simultaneously store data transmitted by the first electronic device 2, such as a smartphone, tablet computer, or laptop computer, and can also transmit data to the first electronic device 2.

[0038] It should be noted that "first", "second", "third" and "fourth" do not refer to the order of clockwise or counterclockwise, but are used to distinguish three different electrical connectors among the N electrical connectors.

[0039] Specifically, the base 10B has multiple sides, and these multiple sides have a total of N openings. The N electrical connectors are disposed inside the housing 10 to couple with the power supply module 12, and correspondingly protrude from the housing 10 through the N openings. For example, Figure 9A , Figure 9B and Figure 10 The plurality of sides are illustrated exemplaryly, including a first side 10S1, a second side 10S2, a third side 10S3, and a fourth side 10S4. Each of the first side 10S1, the second side 10S2, and the third side 10S3 has a first opening 10H1, a second opening 10H2, and a third opening 10H3, such that the first electrical connector 1E1, the second electrical connector 1E2, and the third electrical connector 1E3 are exposed in the receiving body 10 through the first opening 10H1, the second opening 10H2, and the third opening 10H3, respectively. Further, the electrical connection unit 11 is connected to the fourth side 10S4 and has a first connection side 111 and a second connection side 112, wherein the first connection side 111 extends into the interior of the receiving body 10, and the second connection side 112 is used for electrical connection to a power source.

[0040] It should be noted that "first," "second," "third," and "fourth" do not refer to a clockwise or counterclockwise order, but rather are used to describe the first side 10S1, the second side 10S2, the third side 10S3, and the fourth side 10S4 to distinguish the four different sides of the accommodating body 10. Furthermore, in feasible embodiments, the electrical connection unit 11 can be, but is not limited to, a power plug, a USB Type-C electrical connector, a USB Type-A electrical connector, a power socket, or a power cord. For example, Figure 9A , Figure 9B and Figure 10 The electrical connection unit 11 is illustrated as a power plug comprising K metal pins, where K is 2 or 3.

[0041] To explain in more detail, the power supply module 12 is disposed inside the housing 10 and is electrically connected to the second connection side 112. For example... Figure 10 and Figure 12 As shown, the power supply module 12 includes a power conversion unit 121, at least one DC-DC conversion chip 122, a first switching unit 123, and a power management chip 124. The power conversion unit 121 is coupled to the power supply via the electrical connection unit 11 and is used to convert the power supply into a first power supply. Furthermore, the at least one DC-DC conversion chip 122 is coupled to the power conversion unit 121 and is used to convert the first power supply into a second power supply (e.g., 3.3V) and / or a third power supply (e.g., 5.0V, 9.0V), and supplies the second power supply to the control module 13. The first switching unit 123 supplies the second or third power supply to the first electrical connector 1E1. For example, if the third electrical connector 1E3 is a USB 2.0 Type-A connector, the second power supply supplies power to the control module 13 and the first electrical connector 1E1. For another example, if the second electrical connector 1E2 and the first electrical connector 1E1 are USB 3.0 Type-A connectors or USB Type-C connectors, the second power supply supplies power to the control module 13, and the third power supply supplies power to the first electrical connector 1E1 and the second electrical connector 1E2.

[0042] On the other hand, the control module 13 is disposed inside the housing 10 to couple the power supply module 12 to the N electrical connectors (i.e., the first electrical connector 1E1, the second electrical connector 1E2, and the third electrical connector 1E3), and includes at least one memory 13M storing an instruction set, a microprocessor 13P, and a second switching unit 13S. Further, as... Figure 10 and Figure 12 As shown, the first switching unit 123 is coupled between the DC-DC converter chip 122 and the N electrical connectors (i.e., the first electrical connector 1E1, the second electrical connector 1E2, and the third electrical connector 1E3), and the power management chip 124 is coupled between the first switching unit 123, the microprocessor 13P, and the first electrical connector 1E1. In the third embodiment, the power management chip 124 is configured to perform: After the first electronic device 2 is connected to the first electrical connector 1E1, it receives a first battery status information containing a first remaining power level from the first electronic device 2 through the first electrical connector 1E1. When the first remaining power is lower than a predetermined low power threshold, the first switching unit 123 is enabled to perform a first switching operation to establish an electrical connection between the first electrical connector 1E1 and the DC-DC converter chip 122, thereby allowing the second power supply or the third power supply to be transmitted to the first electronic device 2 through the first electrical connector 1E1. When the first remaining power is higher than a predetermined high power threshold, the first switching unit 123 is enabled to perform a second switching operation to disconnect the electrical connection between the first electrical connector 1E1 and the DC-DC converter chip 122. After the second electronic device 3 is connected to the second electrical connector 1E2, it receives a second battery status information containing a second remaining power from the second electronic device 3 through the second electrical connector 1E2. When the remaining power is lower than the predetermined low power threshold, the first switching unit 123 is enabled to perform a third switching operation to establish an electrical connection between the second electrical connector 1E2 and the DC-DC converter chip 122, thereby allowing the second power supply or the third power supply to be transmitted to the second electronic device 3 through the second electrical connector 1E2; and When the second remaining power is higher than the predetermined high power threshold, the first switching unit 123 is enabled to perform a fourth switching operation to disconnect the electrical connection between the second electrical connector 1E2 and the DC-DC converter chip 122.

[0043] Furthermore, if a third electronic device is connected to the third electrical connector 1E3, the power management chip 124 is also configured to perform: After the third electronic device is connected to the third electrical connector 1E3, it receives a third battery status information containing a third remaining power from the third electronic device through the third electrical connector 1E3. When the remaining third power level is lower than the predetermined low power threshold, the first switching unit 123 is enabled to perform a fifth switching operation to establish an electrical connection between the third electrical connector 1E3 and the DC-DC converter chip 122, thereby allowing the second or third power supply to be transmitted to the third electronic device through the third electrical connector 1E3; and When the third remaining power is higher than the predetermined high power threshold, the first switching unit 123 is enabled to perform a sixth switching operation to disconnect the electrical connection between the third electrical connector 1E3 and the DC-DC converter chip 122.

[0044] To reiterate, in the control module 13, the microprocessor 13P is coupled to the memory 13M, the second switching unit 13S, and the N electrical connectors (i.e., the first electrical connector 1E1, the second electrical connector 1E2, and the third electrical connector 1E3). The memory 13M stores an instruction set, and the microprocessor 13P is configured to execute this instruction set. When the first electronic device 2 and the second electronic device 3 are sequentially and correspondingly connected to the first electrical connector 1E1 and the second electrical connector 1E2, the second switching unit 13S is enabled to perform a first switching operation to form a first transmission channel, so that the microprocessor 13P can receive the first data access command and / or the first stored data from the first electronic device 2 through the first transmission channel and the first electrical connector 1E1, and transmit a first read data read from the memory 13M to the first electronic device 2. After the first electronic device 2 is disconnected from the first electrical connector 1E1, the second switching unit 13S is enabled to perform a second switching operation to form a second transmission channel. This allows the microprocessor 13P to receive a second data access command and / or a second stored data from the second electronic device 3 through the second transmission channel and the second electrical connector 1E2, and to access the memory 13M according to the second data access command and / or the second stored data, as well as to transmit a second read data read from the memory 13M to the second electronic device 3.

[0045] In simple terms, when a first electronic device 2 (e.g., a smartphone) and a second electronic device 3 (e.g., a laptop computer) are connected sequentially to the power supply device 1 of this invention, the power supply device 1 will supply power to both the first electronic device 2 and the second electronic device 3 simultaneously. However, only the smartphone, which has the "priority connection," is allowed to access the 13MB of memory. Furthermore, the laptop computer will only be allowed to access the 13MB of memory after the smartphone with the "priority connection" is disconnected from the first electrical connector 1E1.

[0046] Similarly, if a laptop and a smartphone are used as the first electronic device 2 and the second electronic device 3, respectively, and connected sequentially to the power supply device 1 of this invention, the power supply device 1 will supply power to both the laptop and the smartphone simultaneously. However, only the laptop, which is "connected first," is allowed to access the 13MB of memory. Furthermore, the smartphone will only be allowed to access the 13MB of memory after the laptop, which is "connected first," is disconnected from the first electrical connector 1E1.

[0047] Furthermore, if a third electronic device is connected to the third electrical connector 1E3, the power management chip 124 is also configured to perform: After the first electronic device 2 is disconnected from the first electrical connector 1E1 and the second electronic device 3 is disconnected from the second electrical connector 1E2, the second switching unit 13S is enabled to perform a third switching operation to form a third transmission channel. This allows the microprocessor 13P to receive a third data access command and / or a third stored data from the third electronic device through the third transmission channel and the third electrical connector, and to access the memory 13M according to the third data access command and / or the third stored data, as well as to transmit a third read data read from the memory 13M to the third electronic device.

[0048] It should be understood that some electronic product operating systems require verification procedures or permission checks before data access and other operations can be performed. Therefore, the microprocessor 13P is also configured to execute: When the first electronic device 2 is electrically connected to the first electrical connector 1E1, an access control operation and / or a device authentication operation are performed on the first electronic device 2. After the first electronic device 2 passes the access control and / or device authentication operation, the second switching unit 13S is enabled to perform the first switching operation, allowing the first electronic device 2 to access the memory 13M through the microprocessor 13P; and After the first electronic device 2 is disconnected from the first electrical connector 1E1, the permission identification operation and / or the device authentication operation are performed on the second electronic device 3. After the second electronic device 3 passes the permission identification and / or the device authentication operation, the second switching unit 13S is enabled to perform the second switching operation, so that the second electronic device 3 can access the memory 13M through the microprocessor 13P.

[0049] Furthermore, if a third electronic device is connected to the third electrical connector 1E3, the power management chip 124 is also configured to perform: After the first electronic device 2 is disconnected from the first electrical connector 1E1 and the second electronic device 3 is disconnected from the second electrical connector 1E2, the permission identification operation and / or the device authentication operation are performed on the third electronic device. After the third electronic device passes the permission identification and / or the device authentication operation, the switching unit 13S is enabled to perform the third switching operation, so that the third electronic device can access the memory 13M through the microprocessor 13P.

[0050] In summary, the relevant components and functions of the power supply device 1 with storage function of this utility model have been fully and clearly described. It is to reiterate that when the power supply device 1 of this utility model is charging, for example, a smartphone or tablet computer, it can simultaneously store data transmitted by the electronic device and also transmit data to the electronic device.
