Description

[0001] The invention relates to a backpack with a carrying body and a carrying system for wearing on the back of a user, in which an electronic display device is arranged on an outer surface facing away from the user's back. The display device comprises a screen and a local storage medium on which content to be displayed is stored, the screen being configured to display the locally stored content.

[0002] The closest prior art is still considered to be document CN 109711903 A. This document discloses a backpack with an electronic display device in the form of a screen, located on the outer side facing away from the wearer's back, for displaying advertising or multimedia content. The screen is integrated into the backpack body and designed so that it remains within the backpack's outer contour and does not protrude beyond its dimensions. Consequently, the display device is significantly smaller than the back of the backpack. This results in a comparatively small display area with limited visibility from a distance and reduced recognizability, especially in busy environments. Therefore, the solution disclosed in CN 109711903 A is only suitable to a limited extent for advertising applications.Furthermore, the backpack is designed as part of a network- and platform-based system, where the display device primarily serves centrally controlled content distribution and is not geared towards a large-scale, visually dominant display.

[0003] Other publications, in particular CN 110215046 A, CN 201017605 Y, CN 201514749 U, CN 202018802 U, CN 202110783 U, CN 203338712 U, CN 205140416 U, CN 209694341 U, CN 211092326 U, CN 212912159 U, CN 119055033 A and EP 1 511 406 B1, also disclose portable display or advertising devices in which a screen is arranged on a backpack, box or similar device worn by the user. However, these solutions regularly include additional technical measures, such as wireless data transmission, centralized or external content control, synchronization of multiple display units, sensor-based interaction with the environment, advanced power supply concepts, or integration into higher-level operating, network, or platform structures. In some cases, the focus is on modular, connectable, or particularly feature-rich display units, for example, with audio output, camera, projection, or interaction capabilities.However, none of these printed materials prioritizes a simple display device where content is primarily stored locally and played back without mandatory external control or a permanent data connection.

[0004] The object of the invention is to provide a back-worn backpack with an electronic display device in which the perceptibility of the displayed content to outside persons is improved without significantly restricting the mobility and handling of the wearer.

[0005] The problem is solved by a backpack comprising a carrying body and a carrying system for wearing on the user's back, in which an electronic display device is arranged on an outer surface facing away from the user's back. The display device includes a screen and a local storage medium on which content to be displayed is stored, the screen being configured to play back the locally stored content.

[0006] According to the invention, the screen has a display area that extends beyond the back of the carrying body, thereby enabling a large-area display of content that is easily perceptible even from a greater distance. In contrast to known small displays integrated into backpacks, this results in significantly improved visibility and long-range impact, which is particularly advantageous for advertising, informational, or notification applications.

[0007] A further advantage of this design is that the display device can operate independently of a permanent external data connection, thus enabling robust, fail-safe operation even in environments without network coverage. At the same time, the technical design is simplified and energy consumption is reduced.

[0008] As a further embodiment, it may be provided that the screen protrudes at least partially beyond the supporting body or is flush with its outer contour, whereby suitable protective measures, such as transparent covers or shock-absorbing frames, may be provided.

[0009] In a preferred embodiment, the screen is designed as a vertically oriented screen that is wide relative to its height. Due to the vertical screen geometry, the backpack has a smaller lateral width, allowing the wearer to maneuver easily even in confined spaces, such as crowds, narrow aisles, or public transportation.

[0010] At the same time, the portrait orientation provides a large vertical display area, which is particularly suitable for displaying advertising content, text, or moving images. An aspect ratio of at least 16:9 has proven advantageous here, as it offers a good balance between visual impact and ergonomic handling.

[0011] Further designs may include different aspect ratios or curved display surfaces to further improve perception or achieve design effects.

[0012] According to a further embodiment, which provides for the input of content, the storage medium can be written to via a wired interface, in particular a USB interface or a memory card reader. This enables simple, fast and secure updating of the content, for example before use or at a stationary workstation.

[0013] Alternatively or additionally, the storage medium can be writable via a wireless communication interface, in particular Bluetooth and / or WLAN, for the input of content. This allows content to be conveniently transferred via mobile devices or local networks without the need for physical connections.

[0014] The advantage here is that the display device can operate independently of an existing external data connection during playback. The wireless interface is used only for updating the content, not for ongoing control, thus increasing operational reliability.

[0015] In another embodiment, which enables automatic interaction with passers-by, the display device includes a proximity and / or motion sensor, so that the playback of the content can be triggered or switched depending on a detected passer-by event, e.g. to a different image.

[0016] This allows, for example, certain content to be automatically started or the display to be activated when a person approaches.

[0017] Additionally, an optical detection module, in particular a camera, can be provided, which allows interaction events to be derived from image data. This enables situation-dependent adjustment of the display, for example depending on direction of movement, duration of stay, or density of people.

[0018] To enhance interaction, the display device can additionally include an acoustic output unit and / or a visual signaling unit that emits hints or attention signals when an interaction event is detected. This further increases the perception of the display.

[0019] In a further embodiment that enables energy and operational optimization, the display device includes an energy storage unit, wherein the screen brightness can be adjusted depending on an ambient brightness signal and / or the charge level of the energy storage unit. This contributes to energy-efficient use and extends the operating time.

[0020] Additionally or alternatively, an energy-saving mode can be provided, in which the screen is put into a reduced performance state when there is no interaction or after a predetermined period of time. This further minimizes energy consumption without significantly impairing usability.

[0021] In another embodiment, the display unit is designed as a modular, interchangeable unit that is detachably attached to the carrying body. The connection can be made, for example, via an adapter or a zipper. This allows the weight of the backpack to be adjusted as needed, for example, by replacing it with a lighter display unit or by removing the display entirely.

[0022] This modular design also facilitates maintenance, repair and replacement of technical components.

[0023] According to a further embodiment for multi-user and swarm operation, the display unit is designed for wireless pairing with at least one other display unit of another backpack. This allows several backpacks to be used together, for example at events or promotional campaigns.

[0024] This allows for synchronized playback, enabling multiple screens to display the same or coordinated content simultaneously. Alternatively, a role-based distribution can be implemented, particularly according to a master / slave principle, where one display device dictates playback parameters for other displays. Special effects can also be achieved, for example, by running multiple displays side-by-side and showing coordinated content on the screens, creating a unified whole. This allows for a coordinated, large-scale display with distributed display capabilities.

[0025] In a further embodiment, which is particularly suitable for AI-supported content control, the display device includes a processing unit that derives a situational feature from sensor data using a pattern recognition model. The sensor data originates, in particular, from a camera and / or proximity and / or motion sensors. Based on this situational feature, the locally stored content can be automatically selected, sequenced, or parameterized.

[0026] The advantage here is that the model can be executed locally on the processing unit. This keeps the display device independent of external computing systems or cloud services, which improves data protection, response speed, and operational reliability.

[0027] The invention is characterized by the fact that a backpack-worn device enables a particularly highly visible display of content, as the display unit provides an enlarged, bright display area that is easily visible even from a distance and in direct sunlight. At the same time, the backpack remains easy for the wearer to handle, as its design features a narrow lateral width, facilitating passage through narrow spaces. The use of locally stored content allows for simple, reliable operation independent of external data connections, thus reducing technical complexity and expanding the range of applications. Optional sensor, interaction, and energy-saving functions enable on-demand content display and contribute to efficient energy use.Overall, this results in a flexible, practical solution that is suitable for various applications, especially for mobile information or advertising displays.

[0028] The invention will be explained in more detail below with reference to the description of exemplary embodiments and their representation in the accompanying drawings.

The backpack 1 comprises a carrying body 2, which is designed to be worn on the back of a user and has a carrying system 3, which is only partially visible in the illustration and has carrying straps.

[0030] A display device 4 is arranged on an outer side of the support body 2 facing away from the user's back. The display device 4 is designed as a flat, plate-shaped component and extends beyond the back of the support body 2, thus providing an enlarged display area.

[0031] The display device 4 has a display area 6 which is intended for displaying visual content and, due to its size and orientation as well as its high light output, enables good visibility even from a greater distance.

[0032] A detection module 8 is arranged in an upper edge region of the display device 4. This module can be designed to capture environmental information or pedestrian events. The detection module 8 can, for example, be an optical detection module, such as a camera, or a sensor that can detect approaching persons.

[0033] An adapter 10 is arranged between the display device 4 and the support body 2, via which the display device 4 is detachably or permanently connected to the support body 2. The adapter 10 can simultaneously serve for mechanical stabilization, for aligning the display device 4, and for accommodating electrical connections.

[0034] Inside the carrying body 2 are electrical and electronic components intended for operating the display device 4. These may include, in particular, an energy storage unit in the form of a battery or accumulator, as well as a control unit designed to control the display device 4 and manage the content to be displayed. Furthermore, inside the carrying body 2, a local storage device for storing the content, as well as interface and communication units for uploading and updating the content, may be provided. The arrangement of the components within the carrying body 2 enables a protected and compact design as well as a balanced weight distribution when carrying the backpack 1.
