Description

Technical Field

[0001] The utility model belongs to the technical field of dart accessories and relates to a dart target protection device with lighting and automatic scoring functions. Background Art

[0002] Existing dart-shooting leisure activities or competitions mostly utilize simple solid dartboards or electronic dartboards. Existing solid dartboards often require users to calculate their scores, which is inconvenient. Consequently, electronic dartboards are gradually replacing solid dartboards.

[0003] Most existing electronic dartboards utilize sensors mounted on the board to sense the impact of a user's plastic darts, thereby calculating the score. While this method can automatically calculate the score, the dartboard incorporates electronic components, and to avoid damage, the darts are primarily made of plastic. Plastic darts are lighter than traditional darts, resulting in a loss of the user's sense of actual throwing and difficulty controlling their accuracy. Furthermore, the tips of plastic darts are prone to bending and deformation over time, which also impacts accuracy. Utility Model Content
