Projection device

Abstract

The invention provides a shock absorption structure and a projection device including the shock absorption structure. The shock absorption structure includes a first shock pad and a second shock pad,wherein a plurality of air cushion structures are arranged on the upper surface and the lower surface of the first shock pad respectively; a plurality of support structures are equipped among the aircushion structures; the upper surface and the lower surface of the second shock pad are all planes. The projection device guiding in the shock absorption structure includes a casing and a lighting machine arranged inside the casing, wherein a baffle structure of the protection device extends out from a first inner surface of the casing to form a second accommodating space; the shock absorption structure is limited inside the second accommodating space; the shock pad structures are used for separating a lighting machine base from the casing, so as to effectively avoid contact and vibration transmission between the lighting machine base and the casing, and avoid vibration of the projection device caused by vibration during mounting of the lighting machine, and further achieve the effects ofshock absorption and noise reduction.

Description

technical field [0001] The invention relates to a shock absorbing structure and a projection device comprising the shock absorbing structure. Background technique [0002] At present, the display principle of 4K ultra-high density (4K UHD) projector is that inside the projector, the optical component can be moved by two or four positions through an actuation component (extended pixel resolution actuator, XPR) such as an electromagnet, and achieve an increase in resolution. However, the continuous movement (or actuation) of the actuating component causes leakage of vibration energy, and continuous abnormal sound (or noise) is generated due to the leakage of vibration energy, causing considerable trouble to users. Furthermore, when the actuating component is integrated into the optical machine housing of the projector to form a module, the abnormal sound generated by the vibration of the actuating component will produce a speaker effect in the optical machine housing, making ...

Problems solved by technology

However, the continuous movement (or actuation) of the actuating component causes leakage of vibration energy, and continuous abnormal sound (or noise) is generated due to the leakage of vibration energy, which causes considerable trouble to the user.

Furthermore, when the actuating component is integrated into the optical machine housing of the projector to form a module, the abnormal sound generated by the vibration of the actuating component will produce a speaker effect in the optical machine housing, making the abnormal sound louder. Further seriously affect the operating quality of the projector
