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

Abstract

The invention provides a shock absorbing structure and a projection device including the shock absorbing structure. The shock-absorbing structure includes a first shock-absorbing pad and a second shock-absorbing pad. A plurality of air cushion structures are arranged on the upper and lower surfaces of the first shock-absorbing pad, and a plurality of support structures are arranged between the multiple air cushion structures. Both the upper and lower surfaces of the second shock absorbing pad are planes. A projection device introduced into a shock-absorbing structure, comprising a casing and an optical machine arranged in the casing, the projection device extends from the first inner surface of the casing to a retaining wall structure to form a second accommodation space, and the shock-absorbing structure is limited to in the second storage space. The shock absorbing pad structure is used to isolate the optical machine base and the shell, effectively avoiding the contact and vibration transmission between the optical machine base and the shell, and preventing the vibration installed on the optical machine from causing the vibration of the projection device to achieve The effect of shock 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 ...
