AI Technical Summary

Technical Problem

When the projector rotates, the cables connecting the terminals can easily become obstructions, affecting operability.

Method used

The projector uses a hinge unit connected to the bracket frame. The hinge unit suppresses the relative rotation of the projector with respect to the bracket. The wiring runs from inside the projector through the hinge unit and the bracket frame to the connection terminal of the bracket base, thus limiting the rotation range of the projector.

Benefits of technology

It effectively prevents cable damage caused by projector rotation, improving operability and ease of use.

Abstract

The utility model provides a projection system, which is used for improving the operability when a projector is rotated in a structure for supporting the projector to be rotatable. The projection system includes: a projector; a holder that supports the projector; a hinge unit that connects the projector and the holder; and a wiring connected to a circuit board of the projector, the projector having a projection lens and being rotatable relative to the holder about a rotation axis intersecting the optical axis, the holder including: a holder frame connected to the hinge unit; and a stand base supporting the weight of the projector and the stand frame, the stand base having a connection terminal connected to the outside, the wiring reaching the stand base via the projector, the hinge unit, and the stand frame, the hinge unit suppressing relative rotation of the projector with respect to the stand.
