Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to a right-turn blind spot warning device for large vehicles. Background Art

[0002] The blind spot of a car refers to the area that the driver cannot directly observe because his vision is blocked by the car body when he is in the normal driving position, including the front blind spot, the side blind spot and the rear blind spot.

[0003] The inner wheel difference, also known as the "death crescent", refers to the difference between the turning radius of the inner front wheel and the turning radius of the inner rear wheel when the vehicle turns. The existence of the inner wheel difference means that when the vehicle turns, the movement trajectories of the front and rear wheels do not overlap. If the driver only pays attention to the front wheel being able to pass and ignores the inner wheel difference, it may cause the rear inner wheel to drive off the road or collide with other objects. When the car is in a forward moving state, its blind spot is in dynamic change. The front blind spot and the blind spots on both sides are non-blind spots in the previous short period of time. Unless vehicles or pedestrians suddenly break in, it is relatively safe. When the car turns right, the right side blind spot of the car is an absolute blind spot because there is no previous dynamic visible process, which is very dangerous. Therefore, starting from 2021, some parts of the country such as Jinan, Nanjing, Shanghai, Suzhou, Rizhao and other places began to pilot the "right turn must stop", which has been fully promoted nationwide.

[0004] Although the "must stop when turning right" policy does not solve the problem of the blind spot on the right side, it ensures that pedestrians in the blind spot have enough time to leave the blind spot through stopping measures, thus ensuring safety. At the same time, because the vehicle stops and then turns right, new risks arise, namely pedestrians and vehicles entering the blind spot on the right side and the "death crescent" area during the stop period; in view of this, in order to reduce the safety problems caused by the blind spot and inner wheel difference when large vehicles must stop when turning right, the utility model proposes a warning device for the problem of blind spots and inner wheel difference risk areas when large vehicles turn right.
