Description

Technical Field

[0001] The utility model relates to the technical field of electronic school badges, and particularly to an electronic school badge structure. Background Technique

[0002] A school badge, as the name implies, is the badge of a school, marked with the school name on it. It is the symbol and logo of a school. Wearing a school badge is a code of conduct for a student. In the hearts of the older generation of intellectuals, the school badge contains pride, glory, and a sense of belonging to the alma mater. Since 2000, it has been rare to see students wearing school badges on most campuses. Moreover, some students think that wearing a school badge shows superficiality of showing off. Besides, wearing it on clothes also restricts activities. School badges are generally divided into: university school badges, high school school badges, junior high school school badges, primary school school badges, etc.

[0003] For example, the authorized announcement number "CN206182516U" is an electronic school badge. Although there are rubber protrusions installed on the sealing cover, the whole sealing cover is very convenient to disassemble. At the same time, the button battery can be quickly removed and replaced. This structure avoids the trouble caused by overall disassembly. However, for the existing electronic school badges, since the school badge uses a safety pin to pass through the outer fabric of the student's school uniform, and then the electronic school badge is fixed on the school uniform by using the safety pin. However, the end of the safety pin has a relatively sharp tip, which makes it very easy to prick the skin and cause bleeding and injury once the hand shakes or the strength is not well controlled when the safety pin passes through the school uniform. Therefore, the installation and fixation of the existing electronic school badges are relatively dangerous.

[0004] At the same time, for the existing electronic school badges, since there is a PCB board and a button battery inside the electronic school badge to cooperate with the electronic display screen for use. However, both the PCB board and the button battery are relatively afraid of water. And the electronic school badge worn on the outside of the school uniform is very easy to be wetted by rain or forgotten to be taken off during cleaning. In this way, the PCB board and the button battery are washed by water flow or soaked in water together. In either case, it will cause the PCB board and the button battery to get water and short-circuit or malfunction, seriously affecting the service life of the electronic school badge.
