The invention relates to a multifunctional writing tablet powered by solar energy. The writing tablet comprises a writing tablet body and a seal cover. A folder and pen sleeves are arranged on the inner side of the seal cover. Four clamping piece grooves are formed in the writing tablet body, and clamping pieces can be pulled out of or inserted into the clamping piece grooves conveniently. An LED light bar is arranged on each of the upper side, the lower side and the left side of the writing tablet body. The left-side LED light bar is provided with supports and can move upwards and rotate. The lower-side LED light bar is provided with two ultraviolet lamps inside. A solar panel and attraction buckles arranged on the rear side of the writing tablet body, a PCB (printed circuit board) and a lithium battery are arranged in the upper side of the writing tablet body, an independent electronic clock and a three-gear lamp switch are arranged on the surface of the upper side of the writing tablet body, and an external interface is arranged on the side face of the upper side of the writing tablet body. A battery charging clamp is designed independently and can be connected to the external interface. The multifunctional writing tablet can be used as a folder and used for illumination, facilitates writing or material reading, and can be used for time and bank note checking; the multifunctional writing tablet is powered by the solar energy by which internal and external 3.7V lithium batteries can be charged, thereby being convenient to carry, green and energy saving.
Description
technical field [0001] The invention relates to a portable multifunctional writing board, in particular to a multifunctional writing board which can be powered by solar energy for lighting, and can also lead out terminals to charge the battery of a mobile phone. Background technique [0002] At present, most of the writing boards on the market do not have a lighting function, and cannot write, read documents and books when the external light is dark or the indoor lighting is inconvenient, and they do not have the functions of solar power supply and external battery charging. Some writing boards and file folders are all separate, with a single function and structure. The clips on the writing boards are immovable, and the clips are relatively large. This design cleverly integrates these functions into a portable writing board, and also adds electronic watch and ultraviolet function, which can facilitate office workers to check time and check banknotes. Nowadays, people are bu...
