Abstract

A noise reduction structure between a power source and a fixing plate includes: a buffer member having a first opening through upper and lower faces of a body, upper lower portions of the buffer member respectively extending transversely to form upper and lower portion extensions with a gap therebetween; a rigid support portion includes an upper plate block having a second opening, a lower plate block having a third opening, and a stop block connecting the upper plate block and the lower plate block, the buffer member being embedded and engaged between the upper and lower plate blocks; a connecting member having a free end provided with an engagement portion engaged within the gap and a fixing end connected onto the fixing plate; and a fixing rod running through the power source, connecting and fixing the support portion and the power source, being separated from the fixing plate.

First claim

What is claimed is:

1. A noise reduction structure between a power source and a fixing plate, comprising:
a buffer member provided with a first opening penetrating through upper and lower faces of a body of the buffer member, an upper portion and a lower portion of the buffer member respectively extending transversely to form an upper portion extension and a lower portion extension with a gap therebetween;
a support portion made of a rigid material and comprised of an upper plate block provided with a second opening, a lower plate block being provided with a third opening, and a stop block connecting the upper plate block and the lower plate block, the buffer member being embedded and engaged between the upper plate block and the lower plate block;
a connecting member having a free end provided with an engagement portion engaged with the gap and a fixing end connected onto the fixing plate; and
a fixing rod running through the power source, connecting and fixing the support portion and the power source, but being separated from the fixing plate.

2. The noise reduction structure according to claim 1 , wherein the fixing rod is inserted into the second opening of the upper plate block, the first opening of the buffer member and the third opening of the lower plate block in sequence.

3. The noise reduction structure according to claim 1 , wherein
the engagement portion of the connecting member is Ω-shaped or U-shaped so as to form a first protrusion and a second protrusion,
a distance between the first protrusion and the second protrusion is less than a diameter of the buffer member in the gap, and
an internal portion of the buffer member is formed as a cylinder.

4. The noise reduction structure according to claim 3 , wherein the buffer member is provided with a first protection block and a second protection block for preventing the stop block from contacting the first protrusion and the second protrusion,
the first protrusion contacts the first protection block,
the second protrusion contacts the second protection block, and
the stop block is arranged between the first protection block and the second protection block.

5. The noise reduction structure according to claim 3 , wherein a distance between the first protrusion and second protrusion is less than a diameter of the fixing rod.

6. The noise reduction structure according to claim 1 , wherein the buffer member is provided with a first protection block and a second protection block for preventing the stop block from contacting the first protrusion and the second protrusion,
the first protrusion contacts the first protection block,
the second protrusion contacts the second protection block, and
the stop block is arranged between the first protection block and the second protection block.

7. The noise reduction structure according to claim 1 , wherein
the upper portion and the lower portion of the buffer member are provided with a first projection portion and a second projection portion respectively,
the upper plate block of the support portion is provided with a first notch engaged with the first projection portion, and
the lower plate block of the support portion is provided with a second notch engaged with the second projection portion.

8. The noise reduction structure according to claim 1 , wherein the third opening of the support portion is provided to extend downward and form with a threaded recess.

9. The noise reduction structure according to claim 1 , wherein the fixing rod is a screw or a threaded rod with a nut.

10. The noise reduction structure according to claim 1 , wherein
the engagement portion of the connecting member is in an opening shape formed as a fourth opening,
an internal portion of the buffer member is formed as a cylinder, and
a diameter of the fourth opening is larger than that of the cylinder.

11. The noise reduction structure according to claim 10 , wherein
the buffer member is comprised of an end cylindrical portion of the upper portion extension, an end cylindrical portion of the lower portion extension, and a middle cylindrical portion of the internal cylinder,
diameters of the end cylindrical portions are larger than that of the fourth opening and are two times of a diameter of the middle cylindrical portion or less, and
the end cylindrical portions are sized such that they are insertable through and mountable in the fourth opening of the engagement portion of the connecting member after being elastically deformed by a finger.
