Description

Technical Field

[0001] The present invention relates to the technical field of a dining table structure with a self-powered display device, and in particular to a dining table structure which is arranged on a seat of a vehicle and has a cholesterol liquid crystal display device powered by a solar cell. Background Art

[0002] Currently, most public transportation vehicles have dining tables on the backs of seats for rear passengers to use. When the dining tables are folded vertically toward the backs of seats, the space behind the dining tables can be used to convey relevant information to passengers for reference. Taking high-speed rail as an example, relevant information in the train or carriage is mainly drawn behind the dining tables, such as which carriage the toilet or vending machine is located in. When the dining tables are folded vertically toward the seats, passengers can clearly know the configuration information in the train or carriage without having to grope around in the carriage. However, because the carriage information has been fixedly drawn behind the dining tables, if there is other additional information to be conveyed to passengers later, or if the hardware equipment in the carriage needs to be changed, it will inevitably cost a large amount of money to modify it, which will increase the company's hardware cost expenditure. In addition, when station staff dispatch the carriages of the train, they must configure it according to the information behind the dining tables, otherwise the passengers will be at a loss.

[0003] In addition, current airplanes also have dining tables, but the space on the back is mostly blank. Although current airplane seats are equipped with screens on the backs for passengers to watch, important information such as escape instructions are still presented in paper form and placed in the seat pockets. Passengers generally do not take them out to read while sitting in their seats, so they cannot understand in real time how to respond when danger strikes.

[0004] Furthermore, as mobile communication devices become more and more popular today, public transportation vehicles generally do not have charging stations installed, so that passengers can only watch their mobile communication devices run out of power while riding in public transportation vehicles, causing anxiety. Therefore, how to effectively respond to the needs of electronicization and paperlessness through innovative hardware design, so that passengers can easily obtain necessary information such as the carriage or escape when riding in public transportation vehicles, and can charge their own mobile communication devices, etc., is still a problem that developers and researchers in related industries such as public transportation vehicles need to continue to work hard to overcome and solve. Summary of the invention

[0005] Now, the inventor has considered that the dining table structure on traditional public transportation vehicles still has many shortcomings in actual implementation, so he has made improvements with a tireless spirit, assisted by his rich professional knowledge and many years of practical experience, and has developed the present invention accordingly.
