[0001] This utility model relates to the field of storage medium technology, and more specifically, to a USB flash drive that supports dynamic display of images. Background Technology

[0002] USB flash drives are widely used in modern life and work as data storage and transfer devices. With the rapid development of digital products such as mobile phones, cameras, and tablets, the requirements for USB flash drives are also increasing.

[0003] A USB flash drive, or Universal Serial Bus flash drive, is a small, portable storage device primarily used for data storage and transfer. The core components of a USB flash drive include one or more flash memory chips and a controller chip. The controller chip manages data read and write operations. Its interface standard is typically USB, which follows the Universal Serial Bus protocol (USB 2.0 / 3.0 / 3.1) to achieve a physical connection with the host, enabling the USB flash drive to function as a plug-and-play device on most modern computer systems without requiring additional driver installation.

[0004] However, traditional USB flash drives suffer from insufficient interactivity. They typically function as passive data carriers, unable to provide any interactive services. Users cannot obtain dynamic content updates through USB flash drives, lacking interactivity and visual display capabilities. Although some USB flash drives can add personalized elements by customizing icons and background images, the displayed content is fixed and updates are inconvenient. Users cannot update according to their own needs, thus limiting application scenarios. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a USB flash drive that supports dynamic screen display, enabling the linkage between displayed content and stored data. The screen display content can be directly updated by re-burning the FLASH storage module, thus enabling customization according to needs without the need for physical replacement of parts or disassembly of the USB flash drive. It is suitable for advertising, personalized data display and other scenarios.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention by way of example, but should not be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0029] To better understand this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further illustrate the present utility model:

[0030] See Figures 1-3 As shown in the figure, the present invention provides a USB flash drive that supports dynamic display of images, including: a housing 1, a data interface 2, and a display screen 3 disposed on the housing 1. A PCBA circuit board 4 is disposed inside the housing 1. The PCBA circuit board 4 has a built-in FLASH storage module 41 and a processing module 42. The data interface 2 is disposed on the PCBA circuit board 4 and extends through the housing 1 to the outside. The data interface 2 is used to connect to external devices. The dynamic display data of the external devices is transmitted through the data interface 2 and burned into the FLASH storage module 41. The processing module 42 controls the display screen 3 to realize dynamic image display.

[0031] Specifically, when the display screen 3 of the USB flash drive needs to update its display content, it is connected to an external device (such as a computer or mobile phone) through the data interface 2. The dynamic display data prepared on the external device is sent to the USB flash drive through the data interface 2 according to the established data transmission protocol. The data interface 2 acts as a channel for information input and output, transmitting the received data to the FLASH storage module 41 on the PCBA circuit board 4. The FLASH storage module 41 saves this dynamic display data so that it can be called up for screen display at any time later.

[0032] To further explain, this embodiment also provides the working principle of the USB flash drive, as follows:

[0033] First, the processing module 42 reads the pre-programmed dynamic display data from the FLASH storage module 41.

[0034] The status display data includes key instructions such as information for each frame of the screen, display order, and switching time interval.

[0035] Next, the processing module 42 converts the data into electrical signals that the display screen 3 can recognize according to the instructions. By controlling the brightness and color changes of each pixel on the display screen 3, the display screen 3 is controlled to present dynamic images according to the set dynamic effects, thereby realizing the linkage between the displayed content and the stored data. The screen display content can be directly updated by re-burning the FLASH storage module 41. Customization can be achieved according to needs without the need to physically replace parts or disassemble the USB flash drive. It is suitable for advertising, personalized data display and other scenarios.

[0036] See Figures 4-5 As shown, the housing 1 includes an upper shell 11 and a lower shell 12 connected to the rear end of the upper shell 11. In this embodiment, the housing 1 is divided into an upper shell 11 and a lower shell 12, which greatly facilitates the assembly process of the USB flash drive.

[0037] In this embodiment, a first support plate 111 is provided inside the upper shell 11, and a first rib 112 and a second rib 113 are provided on the inner side wall of the upper shell 11. The first rib 112 and the second rib 113 are arranged opposite to each other, and the first rib 112 and the second rib 113 are respectively connected to the first support plate 111. The first rib 112 abuts against one end of the PCBA circuit board 4, and the second rib 113 abuts against the other end of the PCBA circuit board 4.

[0038] Specifically, the first support plate 111 provided inside the upper shell 11 can not only prevent the internal components of the upper shell 11 from deforming due to external pressure, collision and other factors, but also provide an installation platform for the PCBA circuit board 4 and the display screen 3, so that the PCBA circuit board 4 and the display screen 3 can remain relatively flat.

[0039] The first rib 112 and the second rib 113, which are arranged opposite each other on the inner sidewall of the upper shell 11, can limit the position of the PCBA circuit board 4. On the one hand, the first rib 112, the second rib 113, the first support plate 111, and the inner sidewall of the upper shell 11 work together to form a surrounding constraint on the PCBA circuit board 4 from different directions, so that the position of the PCBA circuit board 4 within the shell 1 is limited, preventing displacement due to shaking, and thus preventing hardware damage caused by displacement colliding with the shell 1. On the other hand, the first rib 112 and the second rib 113 play a buffering role to a certain extent. When the USB flash drive is accidentally dropped or impacted, the first rib 112 and the second rib 113 abut against the PCBA circuit board 4, so that there is a deformation space between the PCBA circuit board 4 and the inner sidewall of the upper shell 11. The upper shell 11 can absorb part of the impact force through deformation, reducing the risk of damage to the internal components of the upper shell 11.

[0040] See Figures 4-6 As shown, the lower shell 12 is provided with a first joint portion 121, and the first joint portion 121 is provided with an insertion hole 1211. The upper shell 11 is provided with a corresponding second joint portion 114. When the lower shell 12 is closed and installed on the upper shell 11, at least a portion of the second joint portion 114 is embedded in the insertion hole 1211 to achieve a limiting lock.

[0041] Specifically, the first joint 121 is provided with a first guide inclined surface 1212, and the second joint 114 is provided with a second guide inclined surface 1141 that cooperates with the first guide inclined surface 1212. When the upper shell 11 and the lower shell 12 are closed, the first guide inclined surface 1212 slides along the second guide inclined surface 1141, so that the second joint 114 is partially embedded in the insertion hole 1211.

[0042] This design forms a limiting structure. Through the cooperation of the first guide inclined surface 1212 and the second guide inclined surface 1141, a sliding guide function can be provided during the closing of the upper shell 11 and the lower shell 12, ensuring that the upper shell 11 and the lower shell 12 can be accurately aligned. Through the sliding guide of the inclined surfaces, the assembly personnel can complete the alignment and installation of the upper and lower shells 12 without additional tools or complicated operations, which significantly improves production efficiency.

[0043] In this embodiment, the design of the second joint 114 embedded in the socket 1211 forms a mechanical limiting structure, which can effectively prevent the upper shell 11 and the lower shell 12 from loosening or separating when subjected to external impact or vibration, thereby improving the overall stability of the USB flash drive.

[0044] When the lower shell 12 is installed on the upper shell 11, a portion of the lower shell 12 abuts against the PCBA circuit board 4, so that the PCBA circuit board 4 is clamped between the first support plate 111 and the lower shell 12. Due to the design of the second joint 114 embedded in the socket 1211, the pull resistance of the USB flash drive is enhanced, which can ensure that the USB flash drive can maintain its structural integrity during frequent plugging and unplugging.

[0045] See Figure 3 As shown, the PCBA circuit board 4 has a first clearance notch 43 and a second clearance notch 44 on both sides, respectively. The first clearance notch 43 is corresponding to the first joint 121, and the second clearance notch 44 is corresponding to the second joint 114.

[0046] In this embodiment, the lower shell 12 is provided with a mounting hole 122 that penetrates the thickness of the lower shell 12, and the data interface 2 extends to the outside through the mounting hole 122.

[0047] The U flash drive that supports dynamic display of the screen provided in this embodiment of the utility model also includes a protective cover 5. A second support plate 115 is provided inside the upper shell 11. The second support plate 115 and the inner wall of the upper shell 11 form a slot for installing the protective cover 5. The silk-screened area on the back of the protective cover 5 is fixed in the slot by a first 3M double-sided adhesive. The non-silk-screened area on the back of the protective cover 5 constitutes a visual window.

[0048] Preferably, the display screen 3 is an LCD display screen.

[0049] Preferably, a second 3M double-sided adhesive is provided on the back of the display screen 3, and the display screen 3 is fixed to one side of the first support plate 111 by the second 3M double-sided adhesive, and the PCBA circuit board 4 is fixed to the other side of the first support plate 111.

[0050] Preferably, data interface 2 is a Type-C interface.

[0051] To further explain, this utility model embodiment also provides the circuit principle and circuit diagram of the electronic display screen of the USB flash drive. See the circuit diagram for details. Figure 7 As shown, the circuit principle of the electronic display screen is as follows:

[0052] The animation on the display screen is usually read from the FLASH storage module 41 by the processing module 42 on the PCBA circuit board 4 through a specific interface (such as the SPI-FLASH storage device interface) and the image data from the main control MCU chip is read. The processing module 42 performs necessary processing, such as resolution adjustment and color space conversion, and converts the data into control signals, which are then sent to each pixel of the LCD display screen to control the color and brightness of each pixel so that it displays the corresponding image animation.

[0053] In this embodiment, the processing module 42 is a microcontroller U1, the FLASH storage module 41 is a storage device U2, and the LCD...

[0054] The display circuit principle is as follows:

[0055] When the external power supply is supplied through the V33 voltage terminal, the microcontroller U1, the storage device U2, and the LCD display are in a normal power-on state.

[0056] The microcontroller U1 can handle tasks autonomously, such as transmitting and receiving data. Pins 7, 12, 13, 14, 16, and 17 of the microcontroller U1 are all data pins. Pin 4 is grounded, and pin 6 is connected to the V33 voltage terminal.

[0057] Pin 4 of storage device U2 is grounded. Pins 1, 2, 5, and 6 of storage device U2 are data pins. Pins 3, 7, and 8 of storage device U2 are power pins connected to the V33 voltage terminal.

[0058] Pins 1 and 7 of the LCD display are data pins, pin 2 is grounded, and pins 3, 4, 5, 6, and 8 are data pins, i.e., the data line pins of the display.

[0059] Specifically, pins 7, 12, 13, 14, 16, and 17 of the microcontroller U1 are connected to the storage device U2. The microcontroller U1 first reads the animation image data from the storage device U2, and then...

[0060] The type and interface protocol of U2 determine the appropriate read commands and methods. For example, microcontroller U1 sends a read command via the SPI interface to read data from memory device U2 into its own device, converts it to the corresponding format, and then transfers the processed image data to the LCD driver.

[0061] In this embodiment, the microcontroller U1 sends relevant control signals to the LCD display screen through pins 16, 17, and 18. Pins 12 and 13 of the microcontroller U1 are used to transmit data to the LCD display screen, enabling the microcontroller U1 to sequentially write each frame of the animation data into the frame buffer. Then, the LCD driver reads the data from the frame buffer and displays it on the LCD display screen, achieving the animation display effect. If the animation needs to be changed, the FLASH can be re-programmed.
