Description

Technical Field

[0001] This invention relates to a desktop smart device that includes, for example, USB fast charging and / or wireless charging, allowing users to manage personal affairs while charging. Background Technology

[0002] As smart home applications continue to develop and become more diverse, people's demand for smart office and entertainment systems is deepening. Users often spend extended periods at their desks or in meeting rooms, requiring not only charging of electronic devices but also additional wireless control applications to maximize product functionality. Wireless charging technology, which is widely used, can be utilized to provide this service. Currently, there are four main wireless charging methods: electromagnetic induction, magnetic resonance, radio wave, and electric field coupling. Most mobile phone wireless charging uses the principle of electromagnetic induction.

[0003] Building upon this wireless charging application, there is currently a lack of desktop information management devices that, while providing efficient charging, allow users to access personal information in real time during the charging process, such as text messages, scheduled reminders, and media news. However, current devices that provide reminders still require a frequently used electronic device to continuously operate and transmit data streams, such as paired devices like Bluetooth headsets or speakers. This requires the electronic device to continuously consume power, and the varying levels of power consumption can negatively impact the user experience of other paired devices.

[0004] By adopting the technical solution of the present invention, the above problems can be effectively improved. Summary of the Invention

[0005] Therefore, a desktop manager capable of providing flash charging functionality was designed. This desktop manager utilizes a compact, high-efficiency power supply to exchange energy with the device being charged, thus achieving a "flash charging" effect. Specifically, the product connects directly to AC power via a power plug. The device itself incorporates sensors that establish communication coupling after connecting to an electronic or home appliance. At this point, the desktop manager can perform data transmission actions through its processing unit. Therefore, during "flash charging," users no longer need to periodically monitor whether the electronic device being charged is receiving or sending data. Particularly in some implementations, this product can simultaneously function as a data hub for home appliances.

[0006] Technical Solution: An improved intelligent desktop manager has a flat body with a power input interface for receiving AC or DC power. A prompting unit is provided on a first surface of the body, and a power transmission platform for wireless charging is provided on a second surface. The body contains: a power supply coupled between the power input interface and the power transmission platform for converting between AC and DC power; a protocol processing unit coupled to the power supply for receiving or sending protocol data, wherein the protocol data includes one or more of a charging protocol, a wireless communication protocol, or a data packet transmission protocol; and a communication unit coupled to the protocol processing unit for establishing wired or wireless communication with external devices.

[0007] As an improvement, the power interface is an electrical plug with an extension cable and a cable slot at the bottom of the main body.

[0008] As another improvement, the power supply is a planar power supply to achieve a flat design of the main body. In the examples provided by this invention, the planar power supply refers to significantly reducing the height of one or more integrated circuit boards compared to the conventional height direction, allowing them to be mounted within the aforementioned plate-shaped main body. Since the outer casing (or insulating material) of the plate-shaped main body also has a certain thickness due to rigidity requirements, the thickness of the planar power supply is generally between 3mm and 7mm. Sometimes, the planar power supply structure can also be achieved by dividing such integrated circuit boards into multiple pieces according to, for example, current ratings, and then stacking these integrated circuit sub-boards / distributions in a staggered manner based on the height or volume factors of the electronic components. For example, a flyback oscillator circuit can be designed as a separate panel, complementing the display element in position without increasing the overall height.

[0009] In the above improvements, the protocol processing unit is used to send a flash charging protocol handshake request to the external device to be charged through the communication module after receiving a power coupling signal from the power source, and to estimate the power required to be provided within a preset time period based on the response to the protocol handshake request, so as to control the power source to provide drive for the power transmission.

[0010] Furthermore, in one application aspect of the intelligent desktop manager, the protocol processing unit is also used to send the estimation action to other external devices communicating with the protocol processing unit. This invention provides an information management device that allows users to conveniently manage transaction data while charging electronic devices during their time spent at the desktop. This avoids the potential hazards of using electronic devices while charging and allows users to access personal transaction information in real time, such as SMS messages, scheduled reminders, and media news, even when disconnected from electronic devices. Simultaneously, it fills the gap in the market where charging devices lack intelligent functions and cannot provide AC / DC conversion charging technology. It also helps users continuously transfer workflow data and the types of data streams transmitted on a frequently used device. Attached Figure Description

[0014] Figure 4 This is a functional principle block diagram of the intelligent desktop manager of this invention. Detailed Implementation

[0015] by Figure 1 and Figure 4 The technical solution of the present invention will be described by way of example. Figure 1 A preferred embodiment of a smart desktop manager is shown, the product having a plate-shaped body 1 and a power interface 3, specifically a power plug for connecting to a mains outlet. The plate-shaped body 1 is particularly thin, which allows for a flattened overall structural design. In some alternatives, the power plug has an extension cable 2, and a cable tray 14 can be added to the bottom of the plate-shaped body 1 to achieve... Figure 1 The usage pattern inside. Due to the addition of the cable tray 14, the overall thickness is increased. In order to make better use of the surface space, a prompting unit 13 is provided on the first surface 12. It can be an LCD display, a light-transmitting plate or similar prompting element, so as to facilitate the display of information such as charging status, device configuration, and information playback, and to make it easier for the user to view and obtain information in a timely manner from the front position.

[0016] The second surface 11 of the plate-shaped body 1 provides a platform for wireless charging. The plate-shaped body can be designed to have a larger size so that multiple electronic devices can be placed for charging at the same time.

[0017] In some implementations, the product combines wired and wireless output ports, namely a USB Type-A output port, a USB Type-C output port, and a wireless charging output port. In other implementations, the product integrates a processing unit such as a microcontroller (DSP), enabling intelligent power distribution management across multiple output ports in different application scenarios. In practice, the product's maximum output power reaches 65W. When using a single Type-C port, the maximum output power is 65W, prioritizing the stability of the wireless power output port. When wired / wireless ports are used simultaneously, priority is given to ensuring a maximum wireless charging output power of 15W. This can meet the power needs of most electronic devices / home appliances. Furthermore, in one implementation, the product can store a certain amount of energy as backup power for its own data processing.

[0018] Figure 2 An option is provided: in order to better place electronic devices to achieve the most ideal power exchange efficiency, several positioning components, such as positioning parts 111 and 112, are added to the second surface 11. At the same time, the prompting unit 13 is used to display information prompts for aligning these positioning parts.

[0019] Based on this, other implementation schemes can also be provided. Charging interfaces 121 / 122 are provided on the first surface 12 to provide power transmission to multiple devices. Additionally, a configuration case 123 can be added to the first surface 12 to facilitate user control and selection of the product's functions, such as network configuration. Furthermore, it is desirable to provide network application scenarios for this product.

[0020] As illustrated, during the charging process of electronic devices via the built-in power management module, synchronous communication coupling is established with each electronic device. Through this communication coupling, the desktop manager can forward (e.g., broadcast) data received on electronic device 5 to other nearby available electronic devices. For example, prompts can be sent to the display screen 61 of computer 6, and the forwarded information can be edited and presented in an overview format within a prompt box 601 for user processing. Voice data can be sent or received using computer 6's own speakers / microphone.

[0021] Meanwhile, to balance the operating voltage of multiple devices to be charged (e.g., computer 6 and home gateway 7 simultaneously), the power management unit identifies the connected devices to determine the power supply level and distribution ratio. Furthermore, when receiving power, home gateway 7 uses an indicator 71 to prompt the user whether it is in a powered-on state or performing a communication coupling action with the desktop manager.

[0022] according to Figure 4According to the provided block diagram of the desktop manager, the power supply is a switching power supply AC-DC section, constructed with at least part of the AC mains input terminal as the power draw interface, converting AC 220V power into DC 21V power. Alternatively, the power supply can also be configured to obtain DC power through the power draw interface and convert it into a smaller amplitude (e.g.,) AC 24V power, thereby providing the AC inductive coupling required between the power transmission platform and the external device to be charged.

[0023] In one improvement, the power supply further includes a DC-DC conversion circuit, which can, for example, convert the aforementioned 21V DC power into DC power corresponding to, for example, 5V, 9V, 12V, 15V, and / or 20V, to provide multi-stage output. This DC power includes, for example, the power required for using the flash charging function, or power boosted by the DC-DC conversion circuit before being transmitted to the aforementioned power transmission platform.

[0024] In another improvement, the communication unit may include a Bluetooth module, which is coupled within the aforementioned protocol processing unit and performs functions that can be divided into three parts:

[0025] [Function 1] and Figure 3 The home gateway 7 communicates with the device to notify the device that is being charged on this desktop manager when it receives a notification.

[0026] [Function 2] and Figure 3 After completing power coupling, the device 5 to be charged in the wireless charging module communicates via Bluetooth to read the battery status of the device 5. If the battery level of the device 5 is below 10%, the wireless charging module will activate the flash charging mode to provide flash charging to the device 5, allowing it to quickly charge from a low battery level to 30%.

[0027] [Function 3] Acts as a power management unit, using the collected data... Figure 3 The device 5 uses its power status and data from the wireless charging DC-DC power supply section to control and adjust the output ports of the wired and wireless sections, thereby achieving intelligent power distribution from multiple output ports.

[0028] Therefore, by coupling a step-down DC-DC circuit within (or after) the above DC-DC converter circuit, it is possible to extract and convert the 21V DC power supplied to the power transmission platform into 12V DC power to power the wireless communication module.

[0029] The protocol processing unit can be a protocol controller, responsible for matching wireless protocols or standard protocols with the connected load (such as smartphones, tablets, and other electronic devices), commonly known as a "handshake." After a successful handshake, the load (phones, tablets, and other electronic devices) can be fast-charged. This protocol part controls one USB Type-C port and one USB Type-A port. The function of the USB Type-C output port and the USB Type-A output port as power transmission ports is common knowledge and will not be elaborated here.

[0030] For example, in electromagnetic induction wireless charging, when an electronic device (such as a mobile phone) is charging, the current from the power source passes through the coil (the power supply coil of the wireless charger), generating a magnetic field. When the receiving coil of the electronic device approaches the magnetic field, an induced current is generated, thus enabling the transfer of electrical energy between the phone and the charger. Currently, electromagnetic induction wireless charging has a higher conversion rate than magnetic resonance charging, and is therefore widely used in the field of mobile phone wireless charging.

[0031] Currently, the Qi protocol is the primary solution for electromagnetic induction wireless charging technology. In December 2008, several industry giants, including Philips and Texas Instruments, joined forces to form the Wireless Power Consortium (WPC) to jointly develop the Qi wireless charging standard. Qi is the most widely distributed and popular wireless charging standard globally to date. Because it adopts a unified wireless charging standard, wireless charging functionality is universal across products from different manufacturers, as long as the Qi protocol is used.

[0032] USB PD (Power Deliver) fast charging protocol is a fast charging specification developed by the USB-IF organization and is one of the mainstream fast charging protocols currently available. USB flash charging uses a USB Type-C interface for output, but the presence of a USB Type-C interface does not guarantee support for USB PD fast charging. USB Type-C is a type of USB interface. USB interface types can be categorized as USB Type-A, USB Type-B, and USB Type-C. USB Type-A and USB Type-B also have two different interface specifications: USB Mini-A (B) and USB Micro-A (B).

[0033] The desktop manager with flash charging function can also handle the charging output process. Figure 4For example, the power supply priority of the power transmission platform 4, which serves as the wireless charging function, is set to the highest by default by the protocol processing unit. Regardless of whether there are external devices connected to the USB Type-C output port 6 or the USB Type-A output port 7, as long as the wireless charger 4 has a device charging, its maximum output power is 20W; firstly, the desktop manager of the flash charging function reads... Figure 3 The battery level of device 5 waiting to be charged, if Figure 3 When the battery level of device 5 is below 10%, the wireless charging module will activate the flash charging mode. At this time, the maximum output of the wireless charging module is 20W, which will quickly charge device 5 to 30%. After that, the wireless charging will be output at the normal power of 15W.

[0034] In the above example scenarios, when a device is being charged and USB Type-A output port 7 is not outputting, the maximum output power of USB Type-C output port 6 is 45W; when no device is being charged and USB Type-A output port is not outputting, the maximum output power of USB Type-C output port 6 is 65W. Alternatively, when USB Type-A output port is outputting, the maximum output power of USB Type-C output port 6 is 15W (standard value 5V, 3A).

[0035] Additionally, when a device is being charged on the wireless charging module and the USB Type-C output port is not outputting power, the maximum output power of the USB Type-A output port is 18W. When no device is being charged on the wireless charging module and the USB Type-C output port is not outputting power, the maximum output power of the USB Type-A output port is 18W. When the USB Type-C output port is outputting power, the maximum output power of the USB Type-A output port is 15W (5V, 3A).
