Technical Field

[0001] This utility model relates to the technical field of backpacks, specifically a novel digital display backpack. Background Technology

[0002] In recent years, with the development of personalized needs, a type of backpack with digital display function has appeared on the market. The back of the backpack is equipped with a display screen composed of LED beads, which can display corresponding text, patterns or warning symbols as needed to enhance the overall aesthetics of the backpack, meet people's personalized needs, and provide safety warnings for people's travel.

[0003] For example, a digital display backpack with interactive functionality, authorized by publication number "CN221507738U," solves the problem of existing interactive digital display backpacks lacking data interaction between different backpacks and unable to share image data. This is achieved by incorporating a radio frequency wireless module into the display system, enabling communication between the backpack and a locomotive or multiple backpacks. During use, once a backpack approaches a locomotive or other backpacks, automatic connection is established, allowing for synchronized display of text, images, and icons, or data exchange, thus achieving data interaction. Considering existing interactive digital display backpacks, the display screen is typically fixed in place, requiring complete disassembly, which prolongs disassembly time and leads to low maintenance efficiency. Utility Model Content

[0009] Preferably, the output terminal of the circuit board is electrically connected to the switch button, and the outer wall of the switch button is fixedly connected to the backpack.

[0010] Preferably, the backpack has an interface panel installed on its side, and the output end of the interface panel is electrically connected to the circuit board.

[0011] The novel digital display backpack proposed in this utility model has the following advantages: by pulling the zipper to make a U-shaped movement on the baffle, the rear end of the protective frame is opened, the digital display screen can be removed from the protective frame by pulling the zipper, and the first fixing screw can be turned to remove the protective frame from the circuit board.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] Please see Figure 1-6 In this embodiment, a novel digital display backpack includes a backpack 1 and a cover 2. The outer wall of the backpack 1 is fixedly connected to the cover 2, and the outer wall of the cover 2 is fixedly connected to a first connecting strap 3. The inner wall of the first connecting strap 3 is fastened to a belt buckle 4. By controlling the belt buckle 4 on the second connecting strap 5 to fasten and separate from the first connecting strap 3, the cover 2 on the backpack 1 is opened and locked. The outer wall of the belt buckle 4 and the end of the second connecting strap 5 are fixedly connected to the backpack 1. A protective mechanism 6 is connected to the front end of the backpack 1.

[0022] The protective mechanism 6 includes a protective frame 601. The PPC transparent plate 602 on the surface of the protective frame 601 can prevent sharp objects from directly contacting the digital display screen 7, thus providing protection. The outer side of the protective frame 601 is fixedly connected to the backpack 1, the outer wall of the protective frame 601 is fixedly connected to the PPC transparent plate 602, the inner wall of the protective frame 601 is fixedly connected to the zipper 603, and the outer wall of the zipper 603 is fixedly connected to the cover 604.

[0023] A digital display screen 7 is installed on the inner wall of the protective frame 601. The rear end of the backpack 1 is fixedly connected to the shoulder strap 8. The outer wall of the rear end of the protective frame 601 is connected to the mounting mechanism 9. The mounting bracket 903 is installed between the protective frame 601 and the circuit board 903 by passing through the first fixing screw 901. The mounting mechanism 9 includes the first fixing screw 901. The end of the first fixing screw 901 is threadedly connected to the protective frame 601. The outer wall of the first fixing screw 901 is threadedly connected to the mounting bracket 902 and the circuit board 903. The outer wall of the circuit board 903 is fixedly connected to the mounting bracket 902. The lower end of the mounting bracket 902 is threadedly connected to the second fixing screw 904. The end of the second fixing screw 904 is pressed against the rubber strip 905. The outer wall of the rubber strip 905 is pressed against the battery 906. The output end of the battery 906 is electrically connected to the circuit board 903.

[0024] Pulling the zipper 603 causes the baffle 604 to move in a U-shape, opening the rear end of the protective frame 601. Pulling the digital display screen 7 allows it to be removed from the protective frame 601, and turning the first fixing screw 901 removes it from the protective frame 601 and the circuit board 903. The battery 906 and circuit board 903 on the mounting bracket 903 can be directly removed from the backpack. Disassembly can be selectively performed according to the parts to be repaired, without the need for overall disassembly, thus shortening disassembly time, reducing the possibility of disassembly damage, and improving maintenance efficiency.

[0025] The output terminal of the circuit board 903 is electrically connected to the switch button 10. The outer wall of the switch button 10 is fixedly connected to the backpack 1. An interface panel 11 is installed on the side of the backpack 1. The output terminal of the interface panel 11 is electrically connected to the circuit board 903.

[0026] Working principle:

[0027] Pressing the switch button 10 with a finger controls the battery 906 to power the circuit board 906 and the digital display screen 7. After the Bluetooth module on the circuit board 906 communicates with the APP on the mobile phone, during use, the user can specify to display a certain animation or picture, cycle through multiple animations or pictures, or draw a custom picture and send it to the display system module in the backpack circuit board 906 so that the digital display screen 7 can display various pictures and other content. The USB port and tape interface on the side interface panel 11 of the backpack 1 can charge external mobile phones and other devices and the battery 906 itself, respectively, to meet various usage needs. The PPC transparent plate 602 on the surface of the protective frame 601 can prevent external sharp objects from directly contacting the digital display screen 7, thus improving the service life of the digital display screen 7.

[0028] When the digital display screen 7 is damaged, pull the zipper 603 to make the baffle 604 move in a U-shape, so that the rear end of the protective frame 601 is opened. The digital display screen 7 can be removed from the protective frame 601 by pulling it, which is convenient for the digital display screen 7 to be replaced and maintained. And loosen the first fixing screw 901 to remove the protective frame 601 from the circuit board 903. The protective frame 601 is separated from the mounting bracket 903. At this time, the mounting bracket 903 can be directly removed from the backpack 1. It is convenient to loosen the second fixing screw 904 to remove it from the protective frame 601, so that the rubber strip 905 is separated from the battery 906. The battery 906 on the mounting bracket 903 can be directly pulled out from the side for repair and replacement.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
