Technical Field
[0001] This utility model relates to the technical field of display backpacks, and in particular to a naked-eye 3D display backpack. Background Technology
[0002] Display backpacks are a type of backpack with a display device installed on the back. These display devices are usually flat or flexible screens, or they may use 3D display to show images, thereby achieving the purpose of advertising or decoration.
[0003] 3D displays typically utilize fan-type displays to project images. These fan-type displays are lightweight, usually consisting of one or two display blades, and are powered by a portable power source, allowing them to be directly attached to the back of a backpack; as illustrated in Chinese patent document CN209708528U – A Backpack-Type 3D Fan-Type Display. However, this type of display backpack leaves the entire fan-type display exposed, making it susceptible to damage from bumps and knocks, and also hindering the secure mounting of the 3D fan-type display.
[0004] Therefore, a 3D display backpack is needed that can firmly fix the 3D fan screen without affecting the display effect of the 3D display screen and the normal use of the backpack. Utility Model Content
[0005] The purpose of this invention is to solve the above-mentioned problems and provide a naked-eye 3D display backpack.
[0006] The technical solution of this utility model is: a naked-eye 3D display backpack, including a bag body and a disc-shaped 3D fan screen, with a transparent cover on the outside of the 3D fan screen; the 3D fan screen is installed on the outer rear side of the bag body, and a shoulder strap is correspondingly provided on the outer front side of the bag body;
[0007] The package body is provided with several accommodating spaces, which are arranged side by side in front of and behind each other, and a partition cloth is provided between adjacent accommodating spaces; the partition cloth separates the accommodating spaces so that the items in the two accommodating spaces will not affect each other; and will not affect the 3D fan screen installed behind.
[0008] The rearmost compartment contains a mounting bag, inside which the 3D fan screen is installed. A circular viewing opening is located at the center of the back of the bag, its size matching the 3D fan screen's dimensions; the diameter of the viewing opening is slightly smaller than the diameter of the 3D fan screen's outer shell. The inner cavity of the mounting bag connects to the outer side of the bag through the viewing opening. Installing the 3D fan screen inside the mounting bag and displaying its image through the viewing opening allows the 3D fan screen to be securely mounted inside the bag, preventing damage from impacts and ensuring the display effect is not obstructed. Additionally, the viewing opening provides circumferential restraint to the 3D fan screen's outer shell, preventing it from detaching.
[0009] Preferably, the mounting bag is cylindrical, and its inner cavity matches the outer contour of the 3D fan screen; it can tightly wrap the 3D fan screen to prevent shaking. The outer side of the mounting bag is equipped with a wraparound zipper for easy installation and removal of the 3D fan screen.
[0010] Furthermore, a ring-shaped fixing baffle is fixed at the observation port; the inner diameter of the fixing baffle is the same as the diameter of the observation port, and the outer diameter of the fixing baffle matches the diameter of the mounting bag. The fixing baffle can further reinforce the bag fabric at the observation port, further preventing the bag fabric from tearing or deforming and causing the internal 3D fan screen to fall out.
[0011] Furthermore, the fixing baffle is located inside the fabric of the package body. This prevents the fixing baffle from rubbing against the transparent cover of the 3D fan screen.
[0012] Preferably, the mounting bag is provided with a cable outlet hole. This allows the power cord or data cable of the 3D fan screen to pass through and extend to the outside of the mounting bag, preventing damage caused by friction between the power bank and other devices and the 3D fan screen when placed together.
[0013] Furthermore, the cable exit hole is located at the end of the mounting bag. This allows it to mate with a 3D fan screen, but the cables protruding from the side of the mounting bag result in cluttered wiring within the accommodating space.
[0014] Furthermore, a circular flexible baffle is fixed at the outlet hole, and the flexible baffle has a cross-shaped through groove. After the wire extends out of the outlet hole, the baffle at the through groove clamps and fixes the wire, preventing it from becoming tangled.
[0015] Preferably, the ends of the mounting bag are made of sponge fabric. The sponge fabric material can absorb shock and prevent items in the storage space from bumping into the 3D fan screen.
[0016] Preferably, the backpack has only one storage space, and the installation bag is disposed within this storage space. Having only one storage space allows the backpack to be more streamlined, lighter, and easier to carry.
[0017] The beneficial effects of this utility model are as follows: The naked-eye 3D display backpack of this utility model has the following advantages:
[0018] 1. This utility model installs the 3D fan screen inside the installation bag and displays the image displayed by the 3D fan screen outward through the observation port. This allows the 3D fan screen to be installed inside the bag, avoiding bumps and ensuring that the display effect of the 3D fan screen is not affected.
[0019] 2. In this utility model, a ring-shaped fixing baffle is set at the observation port to reinforce the bag fabric at the observation port and prevent the bag fabric from breaking or deforming, which would cause the internal 3D fan screen to fall out. Attached Figure Description

[0033] Example 1: See Figure 1-8 A naked-eye 3D display backpack includes a bag body 01 and a disc-shaped 3D fan screen 1. A transparent cover is provided on the outside of the 3D fan screen 1. The 3D fan screen 1 is installed on the rear side of the bag body 01, and a shoulder strap 02 is provided on the front side of the bag body 01.
[0034] The package body 01 has several storage spaces 03 arranged side by side, with partitions 04 between adjacent storage spaces 03; each storage space 03 is closed by a zipper 05. The partitions 04 separate the storage spaces 03, ensuring that the items in the two storage spaces 03 do not interfere with each other, and do not interfere with the 3D fan screen 1 installed behind it.
[0035] In this embodiment, there are two accommodating spaces 03; the 3D fan screen 1 has two display blades.
[0036] The rearmost storage space 03 contains a mounting bag 2, inside which the 3D fan screen 1 is installed. A circular observation port 4 is located at the center of the back of the bag body 01, the size of which matches the 3D fan screen 1. The diameter of the observation port 4 is slightly smaller than the outer diameter of the 3D fan screen 1. The inner cavity of the mounting bag 2 communicates with the outer side of the bag body 01 through the observation port 4. Installing the 3D fan screen 1 inside the mounting bag 2 and displaying the image through the observation port 4 allows the 3D fan screen 1 to be installed inside the bag body 01, preventing damage from impacts and ensuring that the display effect of the 3D fan screen 1 is not obstructed. Furthermore, the observation port 4 provides circumferential restraint to the outer shell of the 3D fan screen 1, preventing it from falling off.
[0037] The mounting bag 2 is cylindrical, and its inner cavity matches the outer contour of the 3D fan screen 1, allowing it to tightly enclose the 3D fan screen 1 and prevent it from shaking. The outer side of the mounting bag 2 has a wraparound zipper 05 for easy installation and removal of the 3D fan screen 1.
[0038] A ring-shaped fixing baffle 5 is fixed at the observation port 4; the inner diameter of the fixing baffle 5 is the same as the diameter of the observation port 4, and the outer diameter of the fixing baffle 5 matches the diameter of the mounting bag 2. The fixing baffle 5 can further reinforce the fabric of the bag body 01 at the observation port 4, and further prevent the fabric of the bag body 01 at this point from breaking or deforming, which would cause the internal 3D fan screen 1 to fall out.
[0039] The fixing baffle 5 is set inside the fabric of the bag body 01. This prevents the fixing baffle 5 from rubbing against the transparent cover of the 3D fan screen 1.
[0040] The mounting bag 2 has a cable outlet hole 21. This allows the power cord or data cable of the 3D fan screen 1 to pass through and extend to the outside of the mounting bag 2, preventing damage caused by friction between the power bank and other devices placed together with the 3D fan screen 1.
[0041] The cable outlet 21 is located at the end of the mounting bag 2. It can be used with the 3D fan screen 1, but the cables extend from the side of the mounting bag 2, resulting in messy wiring within the accommodating space 03.
[0042] A circular flexible baffle 3 is fixed at the outlet hole 21. The flexible baffle 3 has a cross-shaped through groove. After the wire extends out of the outlet hole 21, the baffle at the through groove clamps and fixes the wire, preventing it from becoming tangled.
[0043] The end of the mounting bag 2 is made of sponge fabric. The sponge fabric can absorb shock and prevent other items in the storage space 03 from bumping into the 3D fan screen 1.
[0044] The working process of this embodiment includes the following steps:
[0045] ① Open the last compartment 03 of the package body 01;
[0046] ② Unzip the zipper 05 on the installation bag 2 and place the 3D fan screen 1 inside the installation bag 2;
[0047] ③ Pass the wires of the 3D fan screen 1 out through the wire outlet hole 21;
[0048] ④ Adjust the angle and position of 3D fan screen 1;
[0049] ⑤ Pull the zipper 05 to close the installation bag 2; at this point, the 3D fan screen 1 is installed and fixed in place;
[0050] ⑤ Connect the wiring of 3D fan screen 1 to the corresponding device; at this time, 3D fan screen 1 displays the image to the outside through observation port 4;
[0051] ⑥ Pull the zipper 05 to seal the accommodating space 03.
[0052] Example 2: See Figure 8-12 Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that there is only one accommodating space 03, and the installation bag 2 is placed inside this accommodating space 03. Setting only one accommodating space 03 makes the backpack more concise, lighter, and easier to carry.
[0053] In this embodiment, the 3D fan screen 1 has one display blade.
[0054] A combination lock is located on the side of bag 01, which works in conjunction with zipper 05 to ensure the safety of the items inside bag 01.
[0055] Example 3: Example 3 is basically the same as Example 1, and the similarities will not be repeated. The differences are: there are two mounting bags 2, arranged vertically; there are two observation ports 4, and the annular baffle is set as a figure-eight double ring. Two 3D fan screens 1 can be installed in the two mounting bags 2, and the two 3D fan screens 1 can cooperate vertically to achieve richer display effects.
[0056] In the above embodiments, the number of accommodating spaces 03 in the package 01 and the number of display blades in the 3D fan screen 1 can be arbitrarily selected and combined, and embodiments will not be listed one by one here.
