Background

The high-precision map is an electronic map with higher precision and more data dimensions. The accuracy is higher, and the data dimension is more embodied by the fact that the data dimension comprises surrounding static information which is related to traffic besides road information.

The high-precision map stores a large amount of driving assistance information as structured data, and the information can be divided into two types. The first type is road data such as lane information such as the position, type, width, gradient, and curvature of a lane line. The second type is fixed object information around a lane, such as traffic signs, traffic lights, etc., lane limits, junctions, obstacles and other road details, and further includes infrastructure information such as overhead objects, guard rails, number, road edge types, roadside landmarks, etc.

Optionally, the number of the rollers is four, and the four rollers are distributed in an annular array.

Optionally, the rotating shaft is rotatably connected with the mounting groove through a bearing.

Optionally, a second bevel gear is fixedly connected to the bottom end of the rotating shaft, and the second bevel gear is in meshed connection with the first bevel gear.

Optionally, the top of base has seted up the spout, map display screen's bottom swing joint has the pulley, pulley and spout roll connection.

The invention has the technical effects and advantages that:

1. the high-precision map moving device is convenient to drive the high-precision map to move by arranging the idler wheels, is more convenient to move, and is time-saving and labor-saving.

2. According to the invention, through the matching arrangement of the mounting groove, the servo motor, the rotating shaft, the first bevel gear and the second bevel gear, the high-precision map can be conveniently driven to rotate, the angle of the high-precision map can be conveniently adjusted, the high-precision map can be more conveniently observed, and the practicability of the device is improved.
