Description

Technical Field

[0001] The invention relates to the field of power adapters, in particular to a modular, expandable and variable high-power power adapter. Background Art

[0002] With the rapid development of the electronic product market, various electronic devices such as smartphones, tablets, laptops, cameras, game consoles, etc. have become an indispensable part of people's daily lives. As the functions and performance of these electronic devices continue to improve, the demand for power supply and charging is also becoming increasingly diverse. At present, the charging adapters widely used in the market are usually designed for specific power requirements, that is, each device needs to be charged with an adapter of corresponding power. However, this traditional adapter design has the following main problems:

[0003] Poor compatibility: Electronic devices with different power requirements need to be equipped with adapters of different powers, which means that users need to carry multiple adapters when using multiple devices, which is extremely inconvenient.

[0004] Waste of resources: Since each device requires a specific adapter, homes and businesses often accumulate a large number of adapters of different specifications, which not only takes up a lot of storage space but also causes redundancy and waste of resources.

[0005] Inefficiency: In some scenarios that require high-power charging, such as outdoor activities or travel, users may face the problem of insufficient charging adapter power, limiting the charging speed and efficiency of the device.

[0006] In addition, with the advancement of science and technology and the improvement of environmental awareness, people have put forward higher requirements for energy conservation, emission reduction and sustainable development of electronic products. Traditional fixed power adapters are difficult to adapt to diverse charging needs and environmental changes during design, production and use, and cannot meet the development trend of the future electronic product market. Summary of the invention

[0007] To solve the above problems, the present invention provides a modular, expandable and variable high-power power adapter. Through modular design, the adapter can flexibly configure the number of unit adapters as needed, thereby achieving compatibility with different power requirements.

[0008] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a modular, expandable and variable high-power power adapter, including an adapter body, a plurality of unit adapters, a power input line, and a power output line. The adapter body is provided with a main control circuit board, a power output socket connected to the power output line, and a power input socket connected to an external power supply through the power input line, wherein a plurality of unit adapter mounting grooves are provided on the surface of the adapter body, and a unit adapter is detachably mounted in each unit adapter mounting groove, the power input socket is electrically connected to the input end of the unit adapter through a first power receiving end located in the unit adapter mounting groove, the output end of the unit adapter is electrically connected to the main control circuit board through a second connection end located in the unit adapter mounting groove, and the main control circuit board is electrically connected to the power output socket and realizes power supply.

[0009] Furthermore, the adapter body includes a shell base, wherein a plurality of unit adapter mounting grooves are arranged on the shell base, and the first power receiving end is a pair of contact springs arranged in the unit adapter mounting groove, and the unit adapter itself has an adapter power input plug. When the unit adapter is installed in the unit adapter mounting groove, the adapter power input plug is correspondingly plugged into the contact spring, that is, the external power supply can be powered by the unit adapter through the power input socket, the contact spring, and the adapter power input plug.

[0010] Furthermore, the second connection end is a unit adapter connector, and the unit adapter itself has an adapter power output port. The unit adapter cooperates with the unit adapter connector through the adapter power output port to achieve electrical connection with the main control circuit board.

[0011] Furthermore, a display screen is provided on one side of the shell base and is communicatively connected to the main control circuit board.

[0012] Furthermore, a shell flip cover is hingedly mounted on the top of one side of the shell base, and the shell flip cover is provided with a flip cover opening and closing buckle, and the shell base is provided with a buckle slot corresponding to the flip cover opening and closing buckle, and the buckle slot is provided with a flip cover opening and closing button.

[0013] Furthermore, the main control circuit board includes a power management module, a communication interface module, an intelligent control module, a power distribution module, and a display and interaction module, wherein the power management module, the communication interface module, the power distribution module, and the display and interaction module are all communicatively connected to the intelligent control module.

[0014] The beneficial effect of the present invention is that through modular design, the adapter can flexibly configure the number of unit adapters as needed, thereby achieving compatibility with different power requirements. This design greatly expands the power usage range of the adapter, so that a single adapter can meet the charging needs of multiple devices. Compared with traditional fixed power adapters, modular variable power adapters reduce the number of redundant adapters. Users no longer need to purchase adapters separately for each device, but can adapt to the power requirements of different devices by increasing or decreasing the number of unit adapters, thereby improving resource utilization efficiency and reducing waste. Moreover, with the continuous development of electronic devices, their power requirements are also constantly changing. The design of modular variable power adapters enables them to easily adapt to these changes. In the future, if the power demand of the device increases, the user only needs to purchase a higher-power unit adapter for replacement or addition to increase the output power of the entire adapter without replacing the entire adapter. .

DETAILED DESCRIPTION

[0024] See also Figure 1-8 As shown, the present invention relates to a modular, expandable and variable high-power power adapter, as shown in the device structure picture 1 below, the overall device consists of the following parts: an adapter body 1, a plurality of unit adapters 2, a power input line 3, and a power output line 4.

[0025] See also Figure 1 As shown, the adapter body 1 is provided with a main control circuit board, a power output socket 1h connected to the power output line 4, and a power input socket 1d connected to the external power supply through the power input line 3, wherein a plurality of unit adapter 2 mounting grooves are provided on the surface of the adapter body 1, and a unit adapter 2 is detachably mounted in each unit adapter mounting groove 1j, the power input socket 1d is electrically connected to the input end of the unit adapter 2 through a first power receiving end located in the unit adapter mounting groove 1j, the output end of the unit adapter 2 is electrically connected to the main control circuit board through a second connection end located in the unit adapter mounting groove 1j, and the main control circuit board is electrically connected to the power output socket 1h and realizes power supply.

[0026] In this specific embodiment, through modular design, the adapter can flexibly configure the number of unit adapters 2 as needed, thereby achieving compatibility with different power requirements. This design greatly expands the power usage range of the adapter, so that a single adapter can meet the charging needs of multiple devices. Compared with traditional fixed power adapters, modular variable power adapters reduce the number of redundant adapters. Users no longer need to purchase adapters separately for each device, but can adapt to the power requirements of different devices by increasing or decreasing the number of unit adapters 2, thereby improving resource utilization efficiency and reducing waste.

[0027] And as electronic devices continue to evolve, their power requirements are also changing. The modular variable power adapter is designed to easily adapt to these changes. In the future, if the power requirements of the device increase, the user only needs to purchase a higher power unit adapter 2 to replace or add it to increase the output power of the entire adapter without having to replace the entire adapter.

[0028] See also Figure 2-4As shown, in this specific embodiment, the characteristics of the adapter body 1 are further described: it includes a housing base 1a, wherein the housing base 1a is provided with four unit adapter mounting grooves 1j, and the first power receiving end is a pair of contact springs 1i provided in the unit adapter mounting groove 1j, and the unit adapter 2 itself has an adapter power input plug 2b, when the unit adapter 2 is mounted in the unit adapter mounting groove 1j, the adapter power input plug 2b is correspondingly plugged into the contact springs 1i, that is, the external power supply can realize power supply to the unit adapter 2 through the power input socket 1d, the contact springs 1i, and the adapter power input plug 2b. At the same time, the second connection end is a unit adapter connector 1c, and the unit adapter 2 itself has an adapter power output 2c port, and the unit adapter 2 cooperates with the unit adapter connector 1c through the adapter power output 2c port to realize electrical connection with the main control circuit board.

[0029] See also Figure 2-7 As shown, as the basic support structure of the entire adapter, there are 4 unit adapter mounting slots 1j arranged thereon. These slots are designed to accommodate and fix the unit adapters 2 to ensure their stability and safety during use.

[0030] See also Figure 4 As shown, each slot is equipped with a pair of contact springs 1i, i.e., the first power receiving end. This pair of contact springs 1i plays a key role. They cooperate with the adapter power input plug 2b on the unit adapter 2 to realize the transmission of electric energy. When the unit adapter 2 is inserted into the slot, its power input plug will automatically contact and plug with the contact springs 1i, thereby ensuring that the external power supply can smoothly supply power to the unit adapter 2. As an intermediary for power transmission, the design of the contact springs 1i needs to take into account the stability and conductivity of the contact. They can ensure that when the unit adapter 2 is inserted into the slot, a reliable electrical connection is formed so as to transfer electric energy from the power input socket 1d to the unit adapter 2.

[0031] The power input plug of the unit adapter 2 is designed to cooperate with the contact spring 1i on the shell base 1a. When the unit adapter 2 is inserted into the slot, the plug will automatically dock with the contact spring 1i to complete the electrical connection. This design makes the installation and removal of the unit adapter 2 simple and quick. As the second connection end, the unit adapter connector 1c cooperates with the adapter power output 2c port of the unit adapter 2. When the unit adapter 2 is installed in place, its power output port will dock with the connector to achieve electrical connection with the main control circuit board. This design ensures that the output power of the unit adapter 2 can be smoothly transmitted to the main control circuit board and further supplied to the power output socket 1h. As the core control component of the entire adapter, the main control circuit board is responsible for receiving the power from the unit adapter 2, and transmitting the power to the power output socket 1h through its internal circuit processing. At the same time, the main control circuit board may also have other functions, such as power regulation, overload protection, etc.

[0032] See also Figure 3 As shown, further, a display screen 1g is provided on one side of the housing base 1a and is communicatively connected to the main control circuit board.

[0033] The display screen 1g can display the status information of the current adapter in real time, such as the number of inserted unit adapters 2, total output power, voltage, current and other key parameters. In this way, the user can intuitively understand the working status of the adapter without using additional measurement tools. The introduction of the display screen 1g makes the operation of the adapter more intuitive and simple. The user can quickly determine whether the adapter is in normal working condition and whether the number of unit adapters 2 needs to be adjusted or configured by observing the information on the display screen 1g. The display screen 1g is connected to the main control circuit board through a certain communication interface. This connection method ensures that the display screen 1g can receive data and instructions from the main control circuit board in real time and display them to the user in an intuitive form. The main control circuit board is responsible for processing and monitoring the working status of the entire adapter, including the number of unit adapters 2, output voltage, current and other parameters. These parameter information will be transmitted to the display screen 1g in real time for the user to view.

[0034] See also Figure 2 As shown, further, a shell flip cover 1b is hingedly mounted on the top of one side of the shell base 1a, and the shell flip cover 1b is provided with a flip cover opening and closing buckle 1f, and the shell base 1a is provided with a buckle slot corresponding to the flip cover opening and closing buckle 1f, and the buckle slot is provided with a flip cover opening and closing button 1e.

[0035] A shell flap 1b is hingedly mounted on the top of one side of the shell base 1a. This hinged design allows the flap to rotate flexibly on a specific axis, making it easy for users to open and close it. The main function of the flap is to protect the internal circuit and the unit adapter 2 from external factors such as dust and moisture. The shell flap 1b is provided with a flap opening and closing buckle 1f, which is a mechanical device for fixing the position of the flap. When the flap is closed, the buckle will automatically lock on the shell base 1a to ensure that the flap will not be opened accidentally. This design enhances the stability and safety of the adapter. Buckle slots corresponding to the flap opening and closing buckles 1f are provided on the shell base 1a, and these slots are used to accommodate and fix the buckles. At the same time, in order to facilitate the user to operate the opening and closing of the flap, a flip opening and closing button 1e is also provided near the buckle slot. The user only needs to press the button to unlock the buckle and easily open the flip.

[0036] The beneficial effect is that the design of the flip cover effectively protects the circuit inside the adapter and the unit adapter 2, prevents damage from external factors such as dust and moisture, and prolongs the service life of the adapter. When the flip cover is closed and locked, it can prevent the user from unknowingly contacting the internal circuit, thereby reducing the risk of electric shock or short circuit. The design of the flip cover opening and closing button 1e allows the user to easily open and close the flip cover without effort or tools. This convenience improves the user experience.

[0037] See also Figure 8 As shown, further, the main control circuit board includes a power management module, a communication interface module, an intelligent control module, a power distribution module, and a display and interaction module, wherein the power management module, the communication interface module, the power distribution module, and the display and interaction module are all communicatively connected to the intelligent control module.

[0038] The overall workflow is:

[0039] When the user connects the power adapter to an external power source and inserts the unit adapter 2 at the same time, the entire system starts to start. The power management module on the main control circuit board is activated first, receiving the power input from the external power source and converting it into the stable voltage and current required by each module inside the system. At the same time, the intelligent control module is initialized, loading the preset control parameters and algorithms, and preparing to receive and process information from other modules.

[0040] The communication interface module starts to communicate with the inserted unit adapter 2, and identifies key information such as the type and power output capability of each unit adapter 2 through a specific communication protocol (such as the PD protocol). The intelligent control module configures the unit adapters 2 according to the information transmitted by the communication interface module, and determines the connection mode (series or parallel) between them and their respective power output ratios.

[0041] Under the instruction of the intelligent control module, the power distribution module starts to work. It realizes the power distribution and combination between the unit adapters 2 by controlling the on / off and working status of power components such as switch tubes and transformers according to the preset power combination scheme. If the user needs to increase the output power, the power distribution module will combine the power of multiple unit adapters 2; if the output power needs to be reduced, it can be achieved by adjusting the output ratio of each unit adapter 2.

[0042] During the entire working process, the protection and safety monitoring module continuously monitors various state parameters of the system (such as voltage, current, temperature, etc.) to ensure the safe and stable operation of the system. Once an abnormal situation (such as overvoltage, overcurrent, overtemperature, etc.) is found, the protection and safety monitoring module will immediately start the protection measures (such as cutting off the power supply, alarming, etc.) and pass the abnormal information to the intelligent control module and the display and interaction module. The intelligent control module adjusts the control strategy in real time according to the information provided by the protection and safety monitoring module to ensure the stable operation and efficient output of the system. At the same time, the display screen 1g displays the system status information (such as the number of installed unit adapters 2, total output power, voltage, current, etc.) to the user in an intuitive way.

[0043] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention.
