A dual-sided backpack screen Technical Field

[0001] This utility model relates to the field of backpack screen technology, specifically a double-sided backpack screen. Background Technology

[0002] With the diversification of advertising formats, mobile advertising has received increasing attention due to its flexibility and wide coverage. Traditional mobile advertising methods mainly include vehicle-mounted advertising and handheld billboards, but these methods have problems such as limited advertising range, inconvenient operation, and limited display effects.

[0003] Existing backpack advertising screens typically use a fixed display screen structure, with the screen directly fixed to the outside of the backpack, making it impossible to store. This structure is easily damaged by external impacts or weather when carried, and it cannot be effectively stored when not in use, making it inconvenient to carry. In addition, existing backpack advertising screens are usually only set on one side, resulting in limited advertising effect and difficulty in attracting more attention. Summary of the Invention

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6. A double-sided display backpack screen includes a backpack 1, a display screen 2, a battery component, a media player 3, and a lifting mechanism. First, a lifting mechanism is provided inside the backpack 1. The lifting mechanism includes a lifting platform 4, a frame 5, a lead screw 6, and a sliding column 7. That is, the frame 5 is fixedly connected inside the backpack 1, and the sliding column 7 is fixedly connected to the frame 5. The lifting platform 4 is slidably connected to the sliding column 7, and the lead screw 6 is threadedly connected to the lifting platform 4. A drive motor 8 is fixedly connected to the frame 5. The drive motor 8 is poweredly connected to the lead screw 6. When the drive motor 8 drives the lead screw 6 to rotate, the lifting platform 4 can move up and down on the sliding column 7. In addition, a motor controller 9 for controlling the operation of the drive motor 8 is also fixedly connected inside the backpack 1. The motor controller 9 is electrically connected to the drive motor 8, and the motor controller 9 is provided with a control button. The rotation direction of the drive motor 8 can be controlled by the control button.

[0030] Furthermore, a position switch A10 is fixedly connected to the frame 5 near its bottom, and a position switch B is fixedly connected to the frame 5 near its top. Position switches A10 and B are also electrically connected to the motor controller 9. Thus, when the lifting platform 4 moves and abuts against position switch A10 or position switch B, the motor controller 9 controls the drive motor 8 to stop working. At this time, the display screen is located inside the backpack 1 or extends out.

[0031] Secondly, a mounting frame 11 is fixedly connected to the lifting platform 4, and a display screen 2 is fixedly connected to both sides of the mounting frame 11. The backpack 1 is equipped with an entrance and exit in conjunction with the lifting platform 4. The backpack 1 is equipped with a zipper assembly A12 in conjunction with the entrance and exit. When the entrance and exit are opened through the zipper assembly A12, the lifting platform 4 can drive the mounting frame 11 and the display screen 2 on it to extend out of the backpack 1.

[0032] Furthermore, the backpack 1 contains a media player 3, which is used for multimedia output. After connecting the media player 3 to the display screen 2 via a video cable, the video output by the media player 3 can be displayed on the display screen 2.

[0033] Furthermore, the backpack 1 also contains a battery component, which is used to provide power to the display screen 2, media player 3, drive motor 8 and motor controller 9. Specifically, the battery component includes a battery body 13 and a charge / discharge controller 14 electrically connected to the battery body 13. Here, the battery body 13 can be a lithium battery, and the charge / discharge controller 14 is used to output power to the battery body 13 or charge the battery body 13. That is, the charge / discharge controller 14 is equipped with multiple power plugs, and the charge / discharge controller 14 is electrically connected to the display screen 2, media player 3 and motor controller 9 through power lines.

[0034] Furthermore, the operating surfaces of the motor controller 9, the media player 3, and the charge / discharge controller 14 all extend out of the backpack 1, allowing for corresponding operations to be performed from the outside via buttons on the operating surfaces. This means that when carrying the backpack 1, staff can control the lifting mechanism, the media player 3, or the power switch without removing the backpack 1, thus improving operational convenience.

[0035] Furthermore, the back of the backpack 1 is provided with an elastic layer 15, which reduces the rigid contact between the frame 5 and the back when carrying the backpack 1, thereby improving carrying comfort.

[0036] In this embodiment, the backpack 1 has a first storage cavity 16, a second storage cavity 17, and a third storage cavity 18. The first storage cavity 16 has a lifting mechanism, the second storage cavity 17 has a media player 3, and the third storage cavity 18 has a battery component. There are wire holes for various wiring connections between the first storage cavity 16, the second storage cavity 17, and the third storage cavity 18. In addition, the backpack 1 has access ports for the first storage cavity 16, the second storage cavity 17, and the third storage cavity 18. The access ports are equipped with zipper components B19, which can be used to open or close the access ports. This partitioned placement can avoid the squeezing and collision between the components, which can cause damage. It also allows for maintenance of specific components without having to turn the whole bag over, saving time and reducing the complexity of operation.

[0037] At this time, the backpack 1 also has a storage cavity 20 inside, and the backpack 1 has a placement opening to cooperate with the storage cavity 20, and a zipper component C21 is provided at the placement opening.

[0038] It should be noted that the zipper assembly A12, zipper assembly B19 and zipper assembly C21 mentioned in this embodiment are all assemblies of zipper pulls and zipper teeth, which are existing technologies, so their usage and installation will not be described in detail.

[0039] Furthermore, the motor controller 9, position switch, media player 3, display screen 2, battery body 13, and charge / discharge controller 14 in this embodiment can all be selected from commercially available components for use. The specific connection methods between them are based on the functions that can be performed by those skilled in the art, and will not be described in detail here.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
