[0001] This utility model relates to the field of charging docks, specifically a charging dock with a USB-A port output. Background Technology

[0002] Traditional charging docks mainly consist of a casing, internal connecting circuitry, one or a few battery slots, and a power adapter.

[0003] Traditional desktop chargers on the market typically only support charging a single type of battery and lack the ability to charge batteries of different specifications (such as various models of 3.7V lithium batteries), making it difficult to meet the needs of modern homes for multi-purpose integrated devices.

[0004] Moreover, most existing charging docks adopt an open structure without a top protective cover, leaving the battery exposed for extended periods without providing effective safety protection. In addition, these products typically do not integrate a USB-A output port and lack outdoor emergency charging capabilities, failing to meet users' charging needs in different scenarios (such as outdoor environments). Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and meet practical needs by providing a desktop charger with a USB-A output port. This addresses the problem that current desktop chargers on the market typically only support charging a single type of battery, lacking compatibility with different battery specifications (such as various models of 3.7V lithium batteries), making it difficult to meet the demands of modern homes for multi-purpose integrated devices. Furthermore, most existing desktop chargers use an open structure without a top protective cover, leaving batteries exposed for extended periods without effective safety protection. Additionally, these products usually lack an integrated USB-A output port and outdoor emergency charging functionality, failing to meet users' charging needs in different scenarios (such as outdoor environments).

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a charging dock with a USB-A port output is designed, including a middle frame, an upper shell and a lower cover. The upper shell and the lower cover are respectively installed at both ends of the middle frame. The upper shell is rotatably connected to the middle frame. The middle frame has multiple receiving slots for accommodating batteries, and charging components are installed inside the receiving slots.

[0007] Preferably, the charging assembly includes a circuit board, which is attached to the inner top surface of the lower cover and fixedly connected by screws.

[0008] Preferably, the circuit board surface is connected to a USB-A interface and a Type-C interface, and the USB-A interface and the Type-C interface are respectively configured to correspond to the USB-A port and the Type-C port located on the top of the middle frame.

[0009] Preferably, one end of the circuit board is connected to a negative directional hardware, and the other end of the circuit board is connected to multiple positive and negative hardware.

[0010] Preferably, the receiving groove is provided with negative electrode hardware, and a compression spring is installed on the top of the negative electrode hardware to apply elastic pressure to the battery in the receiving groove.

[0011] Preferably, a lens is mounted on the top side of the middle frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model charges the battery via Type-C 5V input and integrates USB-A 5V output function, which can be used to connect other devices for outdoor emergency charging. It supports parallel charging of multiple 3.7V lithium batteries of different models and can discharge them sequentially according to their voltage, thereby balancing the voltage differences between the batteries and fully realizing multi-functional integration.

[0014] 2. The lower cover and middle frame of this utility model are provided with multiple battery slots, and with the help of springs and contact hardware, different types of batteries can be installed stably and easily replaced, avoiding battery shaking during charging and improving the stability and reliability of the equipment.

[0015] 3. This utility model adopts a closable upper shell, which effectively prevents children from accidentally touching it and the battery from falling out, avoids the entry of external dust and foreign objects, and enhances safety during use.

[0016] In summary, with the above multi-functional integrated setup, users do not need to purchase multiple charging devices (such as portable power banks) to meet their charging needs in various indoor and outdoor scenarios, making it more convenient, cheaper, and more environmentally friendly.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A charging dock with a USB-A port output, see [link to example]. Figures 1 to 2 It includes a middle frame 4, an upper shell 1 and a lower cover 8. The upper shell 1 and the lower cover 8 are respectively installed at both ends of the middle frame 4. The upper shell 1 and the middle frame 4 are rotatably connected. The middle frame 4 has multiple receiving slots for accommodating the battery 3. The receiving slots are equipped with charging components.

[0022] The top cover 1 is made of black transparent material, allowing users to view the charging status indicator light without affecting the appearance; when the top cover 1 is closed, it can effectively prevent the battery 3 from slipping or being accidentally touched, enhancing safety during use.

[0023] For details, see Figure 1 The charging assembly includes a circuit board 12, which is attached to the inner top surface of the lower cover 8 and fixedly connected by screws. The surface of the circuit board 12 is connected to a USB-A interface 10 and a Type-C interface 11, which are respectively set to correspond to the USB-A port and the Type-C port set on the top of the middle frame 4. One end of the circuit board 12 is connected to a negative electrode directional hardware 7, and the other end of the circuit board 12 is connected to multiple positive and negative hardware 9.

[0024] A 5V voltage is input through the Type-C interface 11. After the power input is processed by the internal control circuit, it provides a stable charging current to the multiple battery 3 accommodating slots set in the middle frame 4. Each accommodating slot is equipped with a spring 6 for reliable connection with the positive and negative terminals of the 3.7V lithium battery 3, thereby realizing simultaneous charging of different types of lithium batteries 3. The charging status is monitored and controlled in real time by the MCU, and the status indicator circuit displays the current charging progress and whether each battery 3 is fully charged.

[0025] When the user needs to use the USBA port for emergency power supply, the MCU controls the battery 3 to perform boost discharge in sequence according to the voltage of battery 3, so as to ensure that the output voltage is stable at 5V and avoid voltage imbalance caused by multiple batteries 3 discharging at the same time.

[0026] It is worth noting that, see Figure 1 The accommodating slot is equipped with a negative electrode hardware 5, and a compression spring 6 is installed on the top of the negative electrode hardware 5 to apply spring pressure to the battery 3 in the accommodating slot.

[0027] When battery 3 is inserted into the slot, the compression spring 6 at the negative end immediately applies an upward elastic force to battery 3, causing battery 3 to press tightly against the positive terminal metal contact piece. Meanwhile, the positive terminal metal piece forms a stable electrical contact with the positive terminal of battery 3 from the top of the slot downwards. The rebound force of spring 6 can not only compensate for the size difference of different models of battery 3, but also provide a reset function at the moment of installation and removal, ensuring that the operation is simple during replacement.

[0028] It is worth mentioning that, see Figure 1 The lens 2 is installed on the top side of the middle frame 4.

[0029] When using a charging dock with a USB-A output port, a 5V voltage is input through the Type-C interface 11. After the power input is processed by the internal control circuit, it provides a stable charging current to the multiple battery 3 accommodating slots located in the middle frame 4. Each accommodating slot is equipped with a spring 6 for reliable connection to the positive and negative terminals of the 3.7V lithium battery 3, thereby enabling simultaneous charging of different types of lithium batteries 3. The charging status is monitored and controlled in real time by the MCU, and the status indicator circuit displays the current charging progress and whether each battery 3 is fully charged. When the user needs to use the USB-A port for emergency power supply, the MCU controls the batteries 3 to perform boost discharge sequentially according to the battery 3 voltage, ensuring that the output voltage is stable at 5V and avoiding voltage imbalance caused by multiple batteries 3 discharging at the same time.

[0030] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
