Abstract
Description
Technical Field
[0001] The present invention relates to the field of universal charging conversion technology, and in particular to a universal charging converter and a charging method. Background Art
[0002] Currently, all laptop chargers on the market use brand-specific charging identification technology, relying primarily on internally embedded identification chips or resistors with specific resistance values to achieve matching and identification between the charger and the laptop. While different chargers may have the same output voltage and power (e.g., 19.5V, 330W), due to differences in internal identification signals, even with the same connector size (e.g., a 7.4×5.0mm circular connector), chargers from different brands are often not interchangeable. Even within the same brand, compatibility issues can exist between different models. For example, a high-wattage charger cannot charge an earlier-model, low-wattage laptop because the older laptop may not recognize the identification signal embedded in the newer charger. These technical flaws not only require each laptop to be equipped with a dedicated charger, but also lead to the generation of large amounts of electronic waste, impacting resource utilization and environmental protection.

[0024] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.
[0025] Please refer to Figure 1 The present invention provides a universal charging converter, including a shell 1, a hollow structure is provided in the shell 1, a circuit board is provided in the hollow structure, an MCU and multiple charging components are provided on the circuit board, the MCU is connected to the multiple charging components, and the MCU is also connected to an adjustment member. By adjusting the adjustment member, the MCU can be driven to switch multiple charging components to adapt to different laptops.
[0026] In this embodiment, the universal charging converter includes a shell 1. The interior of the shell 1 is hollow and has a hollow structure. A circuit board (PCB) is provided in the hollow structure. A plurality of charging components and an MCU are connected to the circuit board. The MCU is connected to the plurality of charging components, so that the MCU can switch multiple charging components to charge different laptop computers, wherein one charging component corresponds to a laptop computer of a different brand or model. The MCU is also connected to an adjustment member, and the user can drive the MCU to switch different charging components to charge different laptop computers by adjusting the adjustment member. Specifically, a through hole 11 is provided on the shell 1, and the through hole 11 is a pinhole. The user adjusts the adjustment member through the pinhole to select different charging components. Among them, the number of charging components is not limited here and is set according to actual production needs.
[0027] The appearance of the shell 1 is the same as that of a traditional charger, and the interface of the universal charging converter is also the same as that of a traditional charger, such as a standard circular interface of 7.4*5.0mm, thereby ensuring that it matches the interfaces of most chargers and laptops.
[0028] Furthermore, the MCU is also electrically connected to an indicator light 12 , which passes through and is exposed outside the housing.
[0029] In this embodiment, the MCU is also electrically connected to an indicator light 12. One end of the indicator light 12 is connected to the MCU, and the other end passes through the housing 1 and is exposed outside the housing 1. This allows the user to determine the operating mode of the universal charging converter based on the color of the indicator light 12. For example, the indicator light can be used to determine whether the universal charging converter is working, and which charging mode the user is in when adjusting multiple charging components through adjustment members, where each charging component corresponds to a charging mode. In this embodiment, the indicator light 12 is specifically an LED.
[0030] The present invention provides a universal charging converter and a charging method. The universal charging converter includes a shell, a hollow structure is provided in the shell, a circuit board is provided in the hollow structure, an MCU and a plurality of charging components are provided on the circuit board, the MCU is connected to the plurality of charging components, and the MCU is further connected to an adjustment member, which can drive the MCU to switch the plurality of charging components to adapt to different laptop computers by adjusting the adjustment member. The converter provided by the present invention provides a plurality of charging components in the shell, and the plurality of charging components are respectively adapted to the charger identification models of laptop computers of different brands / models, so that the user can adjust the adjustment member according to the models of different laptop computers, thereby driving the MCU to switch different charging components for charging, thereby solving the problem of incompatibility caused by inconsistent identification of existing chargers, reducing production costs, and adapting to charging needs in complex environments.
[0031] Furthermore, the present invention also provides a charging method, which is applied to any of the above-mentioned universal charging converters for connecting a charging power source and a laptop computer, please refer to Figure 2 , Figure 2 FIG. 1 is a flow chart of a charging method for a universal charging converter in an embodiment of the present application, wherein the charging method includes:
[0032] Step 101: pre-set multiple groups of charging components, wherein each group of charging components includes at least an identification parameter corresponding to a certain laptop computer.
[0033] In this embodiment, multiple sets of charging components are pre-installed in the universal charging converter, wherein each set of charging components includes at least identification parameters corresponding to a certain laptop computer, so that the charging components can charge the corresponding laptop computer, and further, the universal charging converter can charge multiple computers of different brands or models.
[0034] Step 102: Based on the MCU, the corresponding identification parameter is loaded according to the charging component selected by the user, and an analog identification signal is output.
[0035] In this embodiment, after the user selects the appropriate charging component based on the laptop brand / model, the MCU loads the corresponding identification parameters based on the selected charging component and begins outputting an analog identification signal. The MCU uses a low-power, high-performance single-chip microcontroller with sufficient computing power to support the storage and output of multiple sets of identification parameters. The MCU internally stores at least four sets of identification parameters for different brands (e.g., Dell / Alienware, Asus, etc.) and models.
[0036] Step 103: Match the output analog identification signal with the identification mechanism of the laptop computer. If the match is successful, charging is performed.
[0037] In this embodiment, after receiving the analog identification signal, the notebook computer matches the received analog identification signal according to its own charger identification mechanism. If the match is successful, normal charging is performed.
[0038] Further, see Figure 3 , Figure 3 This is a schematic diagram of a sub-flow of a charging method for a universal charging converter in an embodiment of the present application. In this embodiment, the MCU loads the corresponding identification parameter based on the charging component selected by the user, specifically including:
[0039] Step 201: adjusting the adjustment element based on the brand / model of the laptop computer by the user;
[0040] Step 202: Switching the corresponding charging component based on the MCU according to the adjustment of the adjustment member;
[0041] Step 203: Load the corresponding identification parameter according to the corresponding charging component through the MCU.
[0042] In this embodiment, the user adjusts the adjustment part according to the brand / model of the laptop computer, and drives the MCU to switch the corresponding charging component through the adjustment part. After the MCU switches to the corresponding charging component, it starts to load the corresponding identification parameters and outputs an analog identification signal.
[0043] Furthermore, the charging component includes an identification chip or resistor adapted to a brand / model of the laptop computer, and the identification chip or resistor includes the identification parameters corresponding to the laptop computer.
[0044] In this embodiment, the universal charging converter is equipped with multiple identification chips or resistors compatible with different laptop brands / models. Each identification chip or resistor is configured with identification parameters (i.e., charging protocol) corresponding to the corresponding laptop brand / model, enabling it to charge the corresponding laptop. The identification chips or resistors are specifically provided on the circuit board.
[0045] Specifically, the specific steps of the charging method of the universal charging converter are as follows:
[0046] The user uses an adjustment element to select the charging component (identification chip or resistor) that matches their laptop. The MCU loads the corresponding identification parameters based on the selected charging component and outputs an analog identification signal. When the universal charging adapter is plugged into the laptop, the charging component is detected by the laptop. If the laptop detects the charging component, the laptop can be used normally. If the laptop cannot detect the compatible charging component or detects the wrong charging component, the laptop will assume that the universal charging adapter is not what it needs and will not charge or will charge at a very low power.
[0047] Through the above method, the incompatibility problem caused by inconsistent charger identification in the prior art is successfully solved. Users only need to make simple adjustments to achieve the interoperability of multi-brand chargers. Through the MCU and multiple charging components, the universal charging converter in the embodiment of the present application can simulate the charger identification signals (such as chip data or resistor values) required by different brands and models of laptops, so that the same charger can be used for a variety of different brands and models of laptop devices after passing through the universal charging converter in the embodiment of the present application, ensuring charging safety and stability, while reducing production costs, promoting the unification of charging standards, and reducing the generation of electronic waste.
[0048] Furthermore, the indicator light includes multiple mode colors and working colors corresponding to multiple groups of charging components, and also includes:
[0049] When the MCU switches to the corresponding charging mode according to the adjustment of the adjustment member, the color of the indicator light is also adjusted to the corresponding mode color according to the corresponding charging mode;
[0050] When the laptop computer is charged through the corresponding charging mode, the MCU switches the mode color of the indicator light to the working color.
[0051] In this embodiment, the indicator light includes multiple mode colors and working colors, wherein the multiple mode colors correspond to multiple groups of charging components respectively. For example, if there are 4 groups of charging components, the indicator light will have 4 mode colors, and each mode color corresponds to a group of charging components.
[0052] When the user uses the adjustment element to drive the MCU to switch the corresponding charging component, the indicator light color also switches to the corresponding mode color. When the user adjusts the corresponding charging component and uses it to charge a laptop, the indicator light color switches from the corresponding mode color to the working color. Specifically, when the user adjusts the adjustment element, the indicator light changes to a different mode color based on the charging component to which the MCU has switched. When the user stops adjusting the adjustment element, the indicator light remains in the mode color corresponding to the charging component. When the user plugs the universal charging adapter into the laptop and charges normally, the indicator light switches from the mode color to the working color. For example, the indicator light has four mode colors: blue, green, yellow, and purple, as well as a white working color. When the user adjusts the mode to the Dell 280W working mode (purple mode color), the indicator light remains purple after the adjustment is completed. When charging a Dell 280W laptop, the indicator light switches from the purple mode color to the white working color, indicating that the laptop is operating normally. When the universal charging adapter is not charging, the indicator light switches from the white working color to the purple mode color, indicating that the laptop is in Dell 280W mode. The user experience can be enhanced by switching between multiple colors of the indicator light.
