摘　　要：Public bulletin boards are widely used in various public places,but due to the large size of the billboards,it is not easy to carry,and the traditional billboards are integrated,when the billboards need to be transferred,the limited storage space of the vehicle needs to be occupied It is extremely inconvenient,and at night,the traditional bulletin boards need to install additional light sources to illuminate them,which greatly increases energy consumption.Based on this paper designed a new structure of the bulletin board,this structure can make the bulletin board when not in use completely folded up and easy to carry,and in use can be completely unfolded and in the bottom of the added retractable support leg structure can be placed anywhere,and according to the terrain or human will to adjust the height.A solar panel is placed on the top of the bulletin board,which can store solar energy during the day and supply energy to the LED lights on the top at night for lighting,which saves energy and is very environmentally friendly.
