[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] As mentioned above, with the rapid development of communication technology and computer technology, numerous terminal equipment brands have emerged in the consumer market in recent years. Each brand often includes multiple types of terminal equipment, such as smart phones, tablets, learning machines, game consoles, etc., which provides consumers with a variety of choices while also intensifying market competition among brands.

[0040] In order to improve the user experience and enhance the market competitiveness of their own products, various brands have launched various terminal functions, and the fast charging function is one of them. The so-called fast charging function means that the terminal device can be charged in a very short time, which improves the charging efficiency and effectively shortens the time when the user is inconvenienced or even unable to use the terminal device due to waiting for the terminal device to charge. Therefore, it can greatly improve the user experience. In actual applications, due to market competition and the confidentiality of their own technology, the fast charging functions of various brands are usually developed independently, resulting in the terminal device can only use the same brand of charging equipment to use the fast charging function, that is, the terminal device of brand A can only use the charging equipment of brand A to activate the fast charging function for charging. If the charging equipment of brand B is used, the fast charging function cannot be activated, and the setting is that the charging equipment of brand B cannot be used for charging.

[0041] For the second-hand equipment recycling industry, various brands are involved when recycling second-hand terminal equipment. Since the recycled terminal equipment requires basic maintenance work such as charging and data processing, in order to be able to use the fast charging functions of various brands and improve charging efficiency, it is necessary to equip fast charging equipment of different brands. This not only requires a large amount of space to store fast charging equipment, but also seriously increases operating costs.

[0042] To solve the above problems, the utility model provides a charging device that can detect the fast charging protocol of a terminal device to be charged, and charge the terminal device to be charged according to the fast charging protocol, thereby meeting the fast charging needs of terminal devices of different brands. Therefore, the same charging device provided by this application can support fast charging of terminal devices of multiple brands at the same time, reducing the number of fast charging devices, saving storage space and reducing operating costs.

[0043] Based on the above, see Figure 1 , Figure 1 1 is a structural block diagram of a charging device provided by the present application. The charging device provided by the present application includes a power supply 10 and at least one charging module 20. The power supply 10 is connected to each charging module 20 respectively to provide power to each charging module 20. Furthermore, each charging module 20 is used to connect to a terminal device 30 to be charged. In actual applications, the power supply 10 charges the terminal device 30 to be charged connected to the charging module 20 through the charging module 20. It should be noted that in Figure 1 In the illustrated embodiment, four charging modules 20 are shown. In actual applications, other numbers of charging modules 20 may be provided as required, which are not listed one by one here.

[0044] Specifically, the configurations of the charging modules 20 are the same. Figure 1 As shown, the charging module 20 includes a fast charging controller 201 and a charging port 202 connected to the fast charging controller 201 .

[0045] Among them, the fast charging controller 201 is configured with multiple fast charging protocols, including at least PD (Power Deliver, power transmission management) protocol, QC (Quick Charge, fast charging) protocol, FCP (Fast Charger Protocol, fast charging protocol), PE (Pump Express, fast charging) protocol and VOOC (Voltage Open Loop Multi-step Constant-Current Charging, open-loop voltage multi-level constant current charging) protocol. Of course, other fast charging protocols that can achieve fast charging can also be included, which are not listed one by one here. Under the premise of not exceeding the core idea of ​​this application, they also belong to the scope of protection of this application.

[0046] Furthermore, the port type of the charging port 202 can also have multiple options, and can be various types of ports that support the USB (Universal Serial Bus) standard, such as a USB-A port, a USB-C port, or at least one of the Lightning ports. Based on this, for the charging device, in the case of including multiple charging modules 20, each charging port 202 can be a charging port of the same type, or can include multiple types of charging ports, for example, 4 USB-C ports, 2 USB-A ports, and 2 USB-C ports. In actual applications, the charging port 202 can be selected in combination with actual use requirements. This embodiment does not exhaustively list all possible types of charging ports, but under the premise of not exceeding the core concept of this application, selecting other types of charging ports also falls within the scope of protection of this application.

[0047] Combination Figure 1 As shown, the output end of the power supply 10 is respectively connected to the power input port of the fast charging controller 201 in each charging module 20, and the power output port of the fast charging controller 201 is connected to the corresponding charging port 202, and finally connected to the terminal device 30 to be charged through the charging port 202.

[0048] Based on the above device configuration, when any charging port 202 of the charging device is connected to a terminal device 30 to be charged, the fast charging controller 201 connected to the charging port 202 detects the fast charging protocol supported by the currently connected terminal device 30 to be charged, and charges the terminal device 30 to be charged according to the fast charging protocol. It is understandable that when the charging device is connected to terminal devices 30 to be charged of multiple brands, the charging device can charge multiple connected terminal devices 30 to be charged at the same time according to the fast charging protocol supported by each terminal device 30 to be charged.

[0049] To sum up, after the charging port of the charging device provided by the present application is connected to the terminal device to be charged, the fast charging controller detects the fast charging protocol of the terminal device to be charged, and charges the terminal device to be charged according to the fast charging protocol. Compared with the prior art, the charging device provided by the present application can identify the fast charging protocol of the terminal device to be charged, and charge the terminal device to be charged according to the fast charging protocol of the terminal device to be charged, thereby realizing the fast charging function and meeting the fast charging requirements of terminal devices of different brands. Therefore, the same charging device provided by the present application can support terminal devices of multiple brands to be fast charged at the same time, thereby reducing the number of fast charging devices, saving storage space and reducing operating costs.

[0050] For further information, see Figure 2 The charging device provided in the embodiment shown in the figure has Figure 1On the basis of the illustrated embodiment, the charging device provided in this embodiment further includes: a controller 40 and an integrated line bus 50 .

[0051] Combination Figure 2 As shown, the controller 40 is connected to the integrated line bus 50, and the integrated line bus 50 is respectively connected to the fast charging controller 201 in each charging module 20. The controller 40 can communicate with each fast charging controller 201 through the integrated line bus 50 to obtain the charging data of each charging module 20. Based on the foregoing content, it can be known that the charging device provided in this application is controlled by the fast charging controller 201 to control the charging process of each connected charging port 202. For any fast charging controller 201, the charging data of the charging module to which it belongs can also be obtained, wherein the charging data includes at least one of the information such as the voltage value, current value, charging rate and charging time during the charging process. Of course, in combination with the actual charging control requirements, other relevant charging data can also be obtained. Based on this, the controller 40 can also obtain the charging data of each charging module 20 through the integrated line bus 50, thereby realizing the monitoring and control of the working status and charging process of each charging module 20, which plays an important role in improving charging stability and safety.

[0052] Furthermore, the controller 40 can also communicate with the host computer ( Figure 2 The charging data of any charging module 20 obtained through the integrated circuit bus 50 is fed back to the host computer, and the host computer monitors the charging process of the terminal device 30 to be charged connected to the corresponding charging module 20 according to the obtained charging data. It can be understood that for the second-hand equipment recycling industry, the quality of the recycled second-hand terminal equipment is uneven, and the charging performance may also vary. The charging equipment provided in this embodiment can upload the charging data during the charging process to the host computer, so that the technicians can understand the performance and defects of the terminal equipment in a timely and accurate manner. In particular, with the help of algorithms in related technologies, the health of the battery of the terminal equipment can also be calculated, so as to carry out targeted and differentiated maintenance and evaluation for each recycled terminal equipment, which plays an extremely important role in the accurate valuation and effective maintenance of the terminal equipment.

[0053] In practical applications, the controller 40 can be connected to the host computer in a variety of ways. In a possible implementation, the controller 40 is connected to the host computer in a wireless communication manner, that is, the controller 40 and the host computer are respectively provided with a wireless communication module, and after a communication connection relationship is established based on the wireless communication module, the controller 40 can upload the obtained charging data to the host computer.

[0054] In another possible implementation, the charging device provided in the present application further includes a communication port, one end of which is connected to the controller 40, and the other end of which is used to connect to a host computer, that is, the controller 40 is connected to the host computer via wired communication, and uploads the obtained charging data to the host computer via a data line.

[0055] Furthermore, regardless of which of the above-mentioned methods the charging device uses to communicate with the host computer, after establishing the communication connection relationship, the host computer can also send control instructions to the controller 40, and the controller 40 can feedback charging data according to the specific circumstances of the obtained control instructions. For example, the host computer sends a data acquisition instruction to the controller 40, and the data acquisition instruction includes a target fast charging controller. It can be understood that the target fast charging controller is any one of the fast charging controllers. The controller 40 determines the target fast charging controller by parsing the obtained data acquisition instruction, and then, the charging data of the target fast charging controller can be obtained through the integrated circuit bus 50, and the obtained charging data can be further uploaded to the host computer.

[0056] It should be noted that the host computer described in this embodiment and subsequent embodiments also includes multiple options, which can be a desktop computer, a laptop computer or a tablet computer. Of course, it can also be other electronic devices with data processing capabilities, which are not listed one by one here. This application does not limit the specific selection of the host computer.

[0057] To summarize, on the basis of the foregoing embodiments, the charging device provided in this embodiment also includes a controller and an integrated circuit bus. The controller is connected to the fast charging controller in each charging module through the integrated circuit assembly, so as to obtain the charging data of each charging module, and realize the monitoring and control of the working status and charging process of each charging module. Furthermore, the charging device can also upload the charging data to the host computer, so that the technicians can understand the performance and defects of the terminal equipment in a timely and accurate manner, thereby performing targeted and differentiated maintenance and evaluation for each recycled terminal equipment, which plays an extremely important role in the accurate valuation and effective maintenance of the terminal equipment.

[0058] Further, based on any of the foregoing embodiments, Figure 3 Shown is another charging device provided by the present application (in Figure 2 Based on the embodiment shown), combined Figure 3 As shown, each charging module of the charging device provided in this embodiment is also provided with a controllable switch Ks.

[0059] Specifically, for any charging module 20 in the charging device, the input end of the controllable switch Ks is connected to the power port of the fast charging controller 201, and the output end of the controllable switch Ks is connected to the charging port 202. Furthermore, the control end of the controllable switch Ks is connected to the control port of the fast charging controller 201, and the fast charging controller 201 controls the conduction and shutdown of each controllable switch Ks through the integrated circuit bus 50.

[0060] In a possible implementation, the fast charging controller 201 receives a control instruction from the controller 40, and controls the on state of the controllable switch Ks in response to the obtained control instruction. For example, the fast charging controller 201 controls the controllable switch Ks to be turned off in response to the off instruction from the controller 40, and the corresponding charging module stops charging the terminal device to be charged, or controls the controllable switch Ks to be turned on in response to the on instruction from the controller 40, and the corresponding charging module charges the terminal device to be charged.

[0061] By setting a controllable switch in each charging module, the controller can control the conduction state of any charging module, and then control the charging function of each charging port. In particular, when a charging module is judged to be abnormal based on the aforementioned charging data, the corresponding controllable switch can be controlled to shut down in time, thereby ensuring the safety of the terminal device connected to the charging port.

[0062] When the controller 40 is connected to the host computer for communication, the host computer can also send a control instruction to the controller 40. The controller 40 responds to the control instruction of the host computer to control the conduction state of the controllable switch Ks in each charging module 20, thereby realizing the host computer's control over the charging process of each charging module 20. Based on this, the communication between the host computer and the controller includes at least one of obtaining charging data and controlling the conduction state of the controllable switch.

[0063] Further, in Figure 3 In the illustrated embodiment, the controller 40 is also connected to the power supply 10 in each charging module 10. The controller 40 can control the working state of each power supply 10, and further control the working state of multiple channels connected to the power supply 10, thereby realizing batch control of each charging port in the charging device and improving control efficiency.

[0064] In a possible implementation, a status indicator light may be provided in any charging module in the charging device, and the status indicator light is connected in series in the corresponding charging module. When the controllable switch in the charging module is turned on, the status indicator light is on to indicate that the corresponding charging port is connected. Correspondingly, when the controllable switch of the corresponding charging module is turned off, the status indicator light is off to indicate that the corresponding charging port is turned off. By providing the status indicator light, the user can intuitively determine the working status of each charging port.

[0065] In summary, compared with the previous embodiment, each charging module in the charging device provided in this embodiment is provided with a controllable switch, and the controller can control the working state of the corresponding charging module through the fast charging controller, thereby realizing independent control of each charging port. The controller is connected to the power supply in the charging device and controls the working state of each power supply, thereby realizing batch control of each charging port in the charging device. Furthermore, the working state of the corresponding charging port can also be displayed through each status indicator light to improve the user experience.

[0066] Furthermore, in the charging device provided by the present application, each charging module also includes a data line authentication module. Figure 3 as well as Figure 4 As shown, in any charging module 20, the data line authentication module 203 is connected to the fast charging controller 201. Based on the above content, it can be known that a variety of preset fast charging protocols can be configured in the fast charging controller 201. Based on this, the data line authentication module 203 is used to authenticate the connection between the fast charging controller and the terminal device to be charged after the fast charging controller 201 detects that the fast charging protocol supported by the terminal device to be charged 30 is the preset fast charging protocol. As for the specific implementation method of the authentication process, it can be implemented with reference to the relevant technology, and this application does not limit this.

[0067] In order to better illustrate the technical advantages of the charging equipment provided by this application, Figure 4 Another charging device is shown, combined with Figure 4 As shown, in the charging device provided in the aforementioned embodiment, the power supply 10 and each charging module 20 connected to the power supply 10 are a charging unit. Based on this, the charging device provided in this embodiment includes two charging units, each charging unit includes a power supply 10 and 4 charging modules 20, that is, includes 4 charging ports 202. Therefore, the charging device provided in this embodiment can charge 8 terminal devices 30 to be charged at the same time. At the same time, since the fast charging controller 201 in each supports multiple fast charging protocols, the charging device provided in this embodiment can simultaneously support the charging of 8 terminal devices 30 to be charged, which can belong to multiple different brands. It can be seen that the charging device provided in this application can realize the functions of multiple charging devices in the prior art, and is not limited by the brand of the terminal device. This application can support terminal devices of multiple brands to be quickly charged at the same time through the same charging device, reduce the number of fast charging devices, save storage space and reduce operating costs. Supporting multiple terminal devices for fast charging at the same time can also greatly improve the charging efficiency.

[0068] Furthermore, the entire charging process can be monitored by acquiring charging data, and the stability and safety of charging can be ensured during the quality inspection of second-hand terminal equipment.

[0069] Furthermore, since the charging device provided by the present application has the charging functions of charging devices of multiple brands, it can effectively reduce the number of charging devices in use, while optimizing resource utilization, reducing the generation of electronic waste, and has a positive impact on protecting the environment and promoting sustainable development.

[0070] For the charging device provided in any of the above embodiments, the power supply is used to provide charging power to each charging module connected thereto, so as to meet the charging requirements of the terminal devices connected to each charging port. In practical applications, the power supply also includes multiple implementations.

[0071] In a possible implementation, the power supply has an energy storage function and can directly output a DC voltage. For example, the power supply can be a lithium battery or other device capable of storing energy. In this embodiment, the power supply can store energy, and when the charging device charges the terminal device, it is not necessary to connect an external power supply. Therefore, the location of the charging device can be moved as needed, which has good flexibility.

[0072] In another possible implementation, the power supply includes a power conversion module that can convert AC power into DC power. In this case, the charging device provided by the present application is also provided with a power port. Specifically, the input end of the power port is used to connect to an AC power supply, and the output end of the power port is respectively connected to the input end of each power supply. The power supply converts the AC power of the AC power supply into DC power matching each charging module through the power conversion module, thereby charging the terminal devices connected to each charging port. It can be understood that compared with the aforementioned embodiment, the charging device provided in this embodiment can be connected to an external power supply, the working time is not affected by the amount of electricity stored in itself, and the endurance is stronger. Moreover, since there is no need to set up a high-cost energy storage device, the overall cost of the charging device is lower.
