Detailed Description
The technical scheme of the invention is further explained by a specific embodiment formula in combination with the attached drawings.
The present invention provides a vibration damping structure, as shown in fig. 2 and 3, which comprises a housing 1, a liner 2, a vibration damping member 3, and a bracket 4, wherein:
the housing 1 is provided with a first chamber 11 and a second chamber 12 which are independent of each other, wherein the first chamber 11 is located below the second chamber 12, and is used for placing the suspension rod 5. Specifically, referring to fig. 2 to 4, an opening 111 is formed at one side of the first chamber 11, the opening 111 is communicated with the space in the first chamber 11, and the shape of the opening 111 is the same as the cross-sectional shape of the end of one end of the suspension rod 5, so that the end of the suspension rod 5 can be placed in the first chamber 11 through the opening 111. In this embodiment, it should be noted that the end of the suspension rod 5 can be set on the bottom wall of the first chamber 11.
The liner 2 is placed in the second chamber 12, and the damping member 3 is disposed between the liner 2 and the inner wall of the second chamber 12. In this embodiment, the damping member 3 may be a rubber column, a spring (disposed in a surrounding manner), or a spring plate, and is preferably a rubber column. By providing the damper 3 between the liner 2 and the second chamber 12, absorption of vibration can be achieved, and noise can be reduced. In this embodiment, the damping members 3 are circumferentially disposed between the liner 2 and the inner wall of the second chamber 12 to achieve damping in various directions, that is, to achieve damping of loads (including rotation, tension, and compression) in different directions.
In this embodiment, the second chamber 12 is preferably a square chamber, the liner 2 is also configured in a square structure, and the side wall of the liner 2 is opposite to four corners of the second chamber 12. The number of the damping members 3 is four, and the four damping members 3 are respectively arranged at the corners of the second chamber 12 and are tangent to the side wall of the liner 2. When the damping piece 3 is installed, the damping piece is arranged between the corner of the second chamber 12 and the side wall of the lining 2 in a pressing-in mode, so that the damping piece 3 can play a role in damping and reducing noise.
