[0029] See Figures 1 to 3 The specific embodiment shown discloses a wireless charging power bank with display function, comprising: a housing 10, wherein a PCB motherboard 20, a battery 30, a Bluetooth module, a display screen 40, and a wireless transmitter 50 are disposed inside the housing 10, and a discharge interface is also provided on the side of the housing 10. The battery 30, the wireless transmitter 50, and the discharge interface are electrically connected to the PCB motherboard 20 to provide both wireless charging and wired charging modes; the Bluetooth module and the display screen 40 are electrically connected to the PCB motherboard 20, and the Bluetooth module is communicatively connected to an external terminal so that the display screen 40 projects the interface of the external terminal.

[0030] Specifically, the Bluetooth module uses a low-power Bluetooth chip, which features high communication stability and low power consumption. A Bluetooth communication circuit is set on the PCB motherboard 20, connecting the Bluetooth module to the PCB motherboard 20. When the user enables the power bank's Bluetooth function, the Bluetooth module begins broadcasting its device information, waiting for connection from an external terminal (such as a mobile phone). The external terminal finds the power bank through the Bluetooth search function and pairs with it. After successful connection, a stable communication link is established between the power bank and the external terminal. The Bluetooth communication function enables wireless connection between the power bank and the external terminal, providing a data transmission channel for subsequent functions such as interface projection. The use of the low-power Bluetooth chip extends the product's battery life and improves its practicality. Additionally, the display screen 40 uses a liquid crystal display (LCD) or an organic light-emitting diode display (OLED), which features high resolution and good display effects. The display screen 40 is connected to the PCB motherboard 20 via a flexible circuit board, and the display driver chip on the PCB motherboard 20 controls the display content of the display screen 40. When the power bank successfully connects to the external terminal via Bluetooth, the power bank's Bluetooth module receives the interface data sent by the external terminal and transmits it to the display driver chip. After processing the data, the display driver chip displays the interface content on the display screen 40. This display function allows users to intuitively view interface information from external terminals, such as notifications, messages, and images on their mobile phones, obtaining relevant information without needing to take out their phones, thus enriching the product's functionality. Simultaneously, the high-resolution display screen 40 provides a clear and realistic display effect, enhancing the user's visual experience.

[0031] In other words, by integrating multiple functions such as wireless charging, wired charging, Bluetooth communication, and display, this product meets the diverse needs of users in different scenarios. Users can choose the appropriate charging method according to the actual situation, and view information from external terminals through the display screen, improving the product's practicality and convenience. Furthermore, the combination of multiple functions brings users a completely new user experience. The convenience of wireless charging, the stability of Bluetooth communication, and the intuitiveness of the display function all contribute to a more comfortable and efficient operating experience. In the increasingly competitive power bank market, this product's innovative design and rich functionality give it a high degree of market competitiveness. It not only meets users' basic needs for power banks but also provides them with more added value, and is expected to gain widespread recognition and application in the market.

[0032] In one embodiment, the housing 10 is further provided with a rotatable U-shaped bracket 60.

[0033] Specifically, the U-shaped bracket 60 is U-shaped and made of high-strength, lightweight engineering plastics (such as polycarbonate PC) or metals (such as aluminum alloys). Engineering plastics offer advantages such as low cost, good formability, and light weight, making them suitable for mass production; metals, on the other hand, offer high strength and a premium feel, enhancing the overall quality of the product. The thickness of the bracket is designed based on material strength and usage requirements, generally controlled between 2-5mm to ensure its strength and stability. Additionally, two symmetrical mounting slots are provided on the housing 10, their shapes matching the ends of the U-shaped bracket 60. The two ends of the U-shaped bracket 60 are inserted into the mounting slots and connected to the housing 10 via a rotating shaft. The rotating shaft is made of metal, offering good wear resistance and rotational flexibility. Limiting devices, such as spring clips or rubber washers, are provided at both ends of the rotating shaft to prevent the bracket from detaching during rotation. This connection structure allows the U-shaped bracket 60 to be stably mounted on the housing 10 and to rotate freely 270 degrees. The limiting device ensures the safety of the bracket during rotation, preventing damage from excessive rotation. Additionally, a damping structure, such as a rubber damping ring or a hydraulic damper, is incorporated inside the rotating shaft. When the user rotates the U-shaped bracket 60 degrees, the damping structure generates resistance, allowing the bracket to remain at any rotational angle without swaying due to its own weight or external forces. Simultaneously, the damping structure is designed to ensure smooth bracket rotation, avoiding any jamming. The application of the damping structure makes adjusting the charging angle more flexible and free, allowing users to place the electronic device at any suitable angle according to their actual needs, improving convenience and comfort.

[0034] In one embodiment, the U-shaped bracket 60 is hinged to both sides of the housing 10 via a cam member 70.

[0035] Specifically, when a user applies an external force to the U-shaped bracket 60, the U-shaped bracket 60 rotates around the cam member 70. During rotation, the cam profile of the cam member 70 interacts with corresponding structures (such as protrusions or grooves) on the U-shaped bracket 60, generating different resistance and positioning effects. When the U-shaped bracket 60 rotates to the desired angle, the curved portion of the cam profile engages with the structure of the U-shaped bracket 60, ensuring stability at that angle. Through the cam profile design of the cam member 70, the U-shaped bracket 60 achieves 270-degree free rotation and can be positioned at any angle, meeting the user's needs for different charging angles. Furthermore, angular positioning is achieved through the friction and geometric constraints between the curved shape of the cam profile and the engaging structure on the U-shaped bracket 60. When the U-shaped bracket 60 rotates to a certain angle, the curved portion of the cam profile is in close contact with the structure of the U-shaped bracket 60, generating sufficient friction to prevent the U-shaped bracket 60 from wobbling due to its own weight or slight external forces at that angle.

[0036] In one embodiment, the inner side of the housing 10 is further provided with a retaining spring 80 corresponding to the cam member 70, and the cam member 70 abuts against the retaining spring 80.

[0037] Specifically, during the rotation of the cam component 70, the retaining spring component 80 elastically deforms along with the movement of the cam component 70, maintaining contact with the cam component 70 at all times. When the cam component 70 rotates to the desired angle, the elastic force of the retaining spring component 80 balances the rotational force of the cam component 70, ensuring the stability of the cam component 70 at that angle. The contact action of the retaining spring component 80 achieves the angular positioning of the cam component 70, allowing the U-shaped bracket 60 to remain stably stationary at different angles, meeting the user's need for flexible adjustment of the charging angle.

[0038] In one embodiment, a gasket 90 is also fitted onto the cam member 70.

[0039] Specifically, the shim 90 acts as a buffer, which can reduce the wear and friction of the cam component 70 and help improve the rotational stability and reliability of the U-shaped bracket 60.

[0040] In one embodiment, the housing 10 is further provided with a partition 100 located inside the retaining spring member 80.

[0041] Specifically, the partition 100 is made of materials with high insulation, high strength, and high temperature resistance, such as plastics (e.g., polycarbonate, polyamide) or ceramic materials. These materials can effectively prevent current conduction, withstand certain external forces and temperature changes, and ensure the stability and reliability of the partition 100 during product use. Furthermore, the partition 100 can be installed on the housing 10 using methods such as snap-fit, screw connection, or adhesive bonding. Snap-fit ​​involves designing corresponding slots and clips on the housing 10 and the partition 100, and installing the partition 100 by snapping it into the slots; screw connection involves drilling holes in the housing 10 and the partition 100, and using screws to fix the partition 100 to the housing 10; adhesive bonding involves using a special adhesive to glue the partition 100 to the housing 10.

[0042] In other words, the presence of the separator 100 effectively prevents the cam 70 from directly contacting the battery 30, avoiding safety issues such as battery short circuits and leakage caused by the movement or malfunction of the cam 70, improving battery safety, extending battery life, and reducing the risk of safety accidents caused by battery malfunctions.

[0043] In one embodiment, the discharge interface is also connected to a charging cable 110, and the end of the housing 10 away from the U-shaped bracket 60 is also provided with a storage groove corresponding to the charging cable 110.

[0044] Specifically, when the user is not using the charging cable 110, the cable is wound or folded along the shape of the storage slot and then placed inside. Additionally, limiting structures (such as clips or baffles) can be installed at the entrance of the storage slot to prevent the charging cable 110 from detaching. When the user needs to use the charging cable 110, they can simply pull one end to remove it from the storage slot. The storage slot is designed to ensure that the charging cable 110 does not encounter excessive resistance during removal and will not be damaged.

[0045] In other words, the charging cable 110 is designed to facilitate wired charging, meeting users' charging needs in different scenarios. The storage slot design allows the charging cable 110 to be neatly stored inside the housing 10 when not in use, avoiding tangling and mess, and improving the overall aesthetics and ease of use of the product.

[0046] In one embodiment, the wireless transmitting component 50 includes a wireless transmitting coil 51 and a magnetic coil 52. The wireless transmitting coil 51 is electrically connected to the PCB motherboard 20, and the wireless transmitting coil 51 is located inside the magnetic coil 52.

[0047] Specifically, the wireless transmitting coil 51 and the magnetic coil 52 work together to magnetically hold the phone and wirelessly charge it. In other words, the ingenious combination of the wireless transmitting coil 51 and the magnetic coil 52 utilizes the principle of magnetic attraction to firmly hold the phone while achieving efficient wireless charging. This design not only improves the convenience of charging but also avoids the problems caused by tangled cables or incompatible interfaces in traditional charging methods. Furthermore, the introduction of the magnetic coil 52 not only enhances the connection stability between the phone and the power bank but also reduces phone shaking during charging through magnetic force, thereby improving charging stability and safety.

[0048] In one embodiment, a push-button switch 120 is also provided on the side of the housing 10, and the push-button switch 120 is electrically connected to the PCB motherboard 20.

[0049] Specifically, the push-button switch 120 allows users to easily control the power bank's on / off state, providing them with direct control and enabling them to turn the power on or off as needed, thus saving energy and extending the power bank's lifespan. Furthermore, by pressing and holding the push-button switch 120, the Bluetooth module can connect to a mobile phone via Bluetooth. This design transforms the power bank from a simple charging device into one capable of communicating with smart devices, thereby expanding its functionality and application scenarios. Additionally, the push-button switch 120's design allows users to control the power bank's on / off state with simple operation, avoiding power waste or safety hazards caused by accidental operation.

[0050] In one embodiment, the housing 10 is further provided with an indicator light, which is electrically connected to the PCB motherboard 20.

[0051] Specifically, indicator lights can display the remaining battery power of the power bank, helping users understand its current status and thus plan their charging time and usage accordingly. This is typically achieved through different colored lights or light flashing frequencies. When the power bank is charging an external device, the indicator light can show the charging status, such as charging in progress or charging complete. This helps users understand the charging progress and avoid overcharging or undercharging. Furthermore, if the power bank malfunctions, such as a battery abnormality or short circuit, the indicator light can issue a warning signal, reminding the user to take timely action. This helps ensure user safety and the normal use of the power bank. In addition, the addition of indicator lights makes the use of the power bank more intuitive and convenient. Users can understand the power bank's working status by observing the indicator light's status, allowing for more confident use.

[0052] In one embodiment, the housing 10 is further provided with a decorative piece 130 on the outside of the display screen 40.

[0053] Specifically, the decorative piece 130 is located on the outer side of the display screen 40 and can play a certain protective role, preventing the display screen 40 from being scratched, bumped, and worn by external objects. For example, the glass decorative piece 130 has high hardness and wear resistance, which can effectively protect the surface of the display screen 40 from damage.

[0054] In one embodiment, the housing 10 consists of a front cover 11, a middle frame 12, and a bottom cover 13, with the front cover 11 and the bottom cover 13 respectively connected to the middle frame 12. The PCB motherboard 20, battery 30, U-shaped bracket 60, and charging cable 110 are connected to the middle frame 12, the wireless transmitter 50 is connected to the front cover 11, and the display screen 40 is connected to the bottom cover 13.

[0055] Specifically, the overall structure of the product is made more stable and reliable through the reasonable composition and connection of the shell 10 and the stable connection of the internal components. For example, the metal middle frame 12 provides solid support for each component, and the snap-fit ​​connection and screw fixing methods ensure the tight connection between the components and prevent the components from loosening or shifting.

[0056] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
