In the technical scheme, the corner on the shell 110 can be processed into an arc shape, and the outline of the outer edge of the corner of the shell 110 is arc-shaped, so that the shell 110 is convenient to be placed in other equipment when being assembled in the other equipment, and the required space is smaller; the inner edge profile of the shell 110 is arc-shaped, and the arc-shaped design can avoid the rotation of the frame 120, so that the rotation of the frame 120 is more convenient, and the size of the scanning assembly is reduced.

In one possible embodiment, the reflecting member 130 is a flat mirror, and the reflecting member 130 includes: the plate body is rotatably connected to the frame 120 along the second direction; the reflecting film is coated on the plate body, so that the reflecting member 130 is a plane mirror.

It is understood that the reflective film may be a dielectric film or a metal film.

In this embodiment, the reflecting member 130 is a flat mirror, and the reflecting prism is larger than the reflecting prism, so that the overall size of the motor is increased after the motor is mounted on the motor, and further, the reflecting member is rotated about the X, Y axis, if the reflecting prism is used, the rotation angle of the reflecting member is reduced. The rotation angle of the reflecting prism is generally smaller than 5 degrees, and can reach about 17 degrees through the arrangement of the plane mirror. And the total reflection prism only reflects in the total reflection angle range, when the angle is smaller than the total reflection angle, the total reflection prism does not emit reflection, and the reflection film can reflect at any angle.

In some examples, the reflective film may include a metal film and a dielectric film, which solves the problem of the metal film having no high reflectivity of the dielectric film and the problem of the dielectric film having low reflectivity at the wide angle reflective film. The common dielectric film needs to be coated with a multilayer film to solve the problem of low large-angle reflectivity, so that the cost is higher and the yield is low. From the aspects of assembly yield, mounting process and reliability, the direct coating of the product is more reliable than the direct mounting of the total reflection prism or the direct mounting of the reflecting mirror.
