Problems solved by technology

[0004] However, the assembly of the shock absorber 130 is time-consuming, especially when the motor is small in size and thus the size of the shock absorber is reduced accordingly, such as a color wheel motor in a projector.
Moreover, the shock absorber 130 will be locked by the screw 110 strongly, resulting in a poor positioning effect, unable to effectively block the resonant high-frequency noise and the starting high-frequency noise generated between the clamping piece 102 and the mechanism fixing piece 120

[0022] Please refer to Figure 2A , which shows a side view of the structure of the motor fixed to the mechanism fixing member configured with the motor damping device according to the first embodiment of the present invention. A general motor 200, such as a projector color wheel motor, has a clamping part 202 for locking on the mechanism fixing part 210, and the mechanism fixing part 210 has the above-mentioned three equidistant two-dimensionally arranged locking holes 212 (for To avoid complicated illustrations, the side view only shows two locking holes 212 ), which are used to lock the clamping part 202 and the mechanism fixing part 210 with screws 214 . The motor damping device 220 is disposed on the mechanism fixing part 210 to reduce the vibration of the motor transmitted from the clamping part 202 directly or via the screw 214 to the mechanism fixing part 210 .

Abstract

A motor damping device includes multiple damping pieces and a connection part, in which, the damping pieces are matched on the fastening holes of the fixing unit to slow down the motor vibration transferred to the fixing unit and the connection part connecting the damping unit.

Description

technical field [0001] The invention relates to a motor damping device, in particular to a motor damping device which blocks high-frequency noise generated by motor rotation. Background technique [0002] Figure 1A It is a structural side view of the existing motor fixed to the mechanism fixture. Please refer to Figure 1A Generally, the motor 100 has a clamping part 102 and is locked on the mechanism fixing part 120 by screws 110 . Since both the clamping part 102 and the mechanism fixing part 120 are sheet metal parts, if no medium is added between them for buffering, the vibration energy of the motor is easily transmitted from the clamping part 102 to the mechanism fixing part 120, making the difference between the two kinds of sheet metal parts between resonant frequencies. Coupled with the multiplication effect of the resonant frequency of different sheet metal materials, it will lead to high-frequency noise. [0003] Figure 1B as well as Figure 1C It is the rea...
