Road sign unit and road sign group

Abstract

The invention discloses a road sign unit. The road sign unit comprises an embedded piece and a covering piece, wherein the embedded piece comprises an embedded part and an embedded connection part, and the embedded connection part is located on the embedded part; the embedded piece is covered with the covering piece, and the covering piece is detachably connected with the embedded connection part.Since the covering piece is not prone to crack or damage, when the road sign unit replaces an original road sign unit made of paint, the service life can be greatly prolonged. A road sign group comprises a plurality of road sign units, and further comprises a total controller and a total storage battery, wherein the road sign units are electrically connected with the total controller and the total storage battery, and the total controller is used for controlling the on / off state and the color of luminous pieces. A photovoltaic module can receive external light through photovoltaic light-permeable holes so as to generate electricity, and then the luminous pieces are made to give out light; the total storage battery is used for storing the electricity. The total controller is used for controlling the lighting states of the luminous pieces of all the road sign units, and therefore, pedestrians and vehicles are more effectively indicated.

Description

technical field [0001] The invention relates to the technical field of road signs, in particular to a road sign unit and a road sign group. Background technique [0002] In road signs, pedestrian crossing lines are generally composed of multiple parallel white solid lines, like the lines on zebras, so they are called zebra crossings. The function of zebra crossings is to guide pedestrians to cross the road or intersection safely. [0003] Pedestrian crossing lines generally adopt a group of white parallel thick solid lines, the line width should be 40cm or 45cm, the line spacing should be 60cm, the maximum should not exceed 80cm, the width of pedestrian crossing lines should be greater than or equal to 3m, and should be widened by 1m. In the prior art, the white lines of pedestrian crossings are generally painted with hot-melt, water-based or room-temperature solvents. Due to the perennial wind and sun, it is easy to cause color darkening, chapping or damage, and it is not e...

Problems solved by technology

In the prior art, the white lines of pedestrian crossings are generally painted with hot-melt, water-based or room-temperature solvents. Due to the perennial wind and sun, it is easy to cause color darkening, chapping or damage, and it is not easy for people to see clearly at night or in the dark. It affects the judgment of pedestrians and the judgment of driving vehicles. It needs to be refreshed every once in a while.
