Patent ID: 7798651

Claim:
A fixing mechanism for fixing a light valve of an optical engine and a thermal module, the thermal module being disposed on a side of the light valve and connected to the light valve for dissipating heat generated by the light valve, the optical engine further comprising an interface board installed between the light valve and the thermal module, the fixing mechanism comprising: a first fixing component installed on a side of the light valve and passing through the thermal module and the interface board, the first fixing component comprising: a first end fixed on the optical engine; and a second end on which a first holding surface is disposed; a second fixing component installed on the other side of the light valve and passing through the thermal module and the interface board, the second fixing component comprising: a first end fixed on the optical engine; and a second end on which a second holding surface is disposed; a first elastic component comprising: a first end connected to the first holding surface; and a second end connected to the interface board; a second elastic component comprising: a first end connected to the second holding surface; and a second end connected to the interface board; and a third elastic structure comprising: a first side connected to the first holding surface and the second holding surface; and a second side located opposite to the first side and connected to the thermal module.
