Abstract:
1. A magnetic fix structure applying on a projection device, the projection device comprising a projection module housing having an inner bottom surface and a power module housing, the magnetic fix structure comprising: a first magnetic connector set comprising at least three magnetic units disposed on a bottom portion of the projection module housing; and a second magnetic connector set comprising at least three magnetic units disposed on a top portion of the power module housing corresponding to the at least three magnetic units of the first magnetic connector set respectively; wherein the first magnetic connector set magnetically attracts the second magnetic connector set so as to allow the projection module housing to be fixed on the power module housing and the projection module housing defines two virtual axes, the virtual axes are perpendicular to each other and are defined a virtual surface parallel to the inner bottom surface, one of the virtual axes is perpendicular to an edge of the inner bottom surface, wherein a line that passes through any two of the three magnetic units of the first magnetic connector set is drawn, the line would not be parallel with either of the two virtual axes.
