Embodiment 1

[0041] see figure 1 As shown, the embodiment of the present invention provides a suspension damping device, the suspension damping device includes:

[0042] Suspension rod 1 and a plurality of damping units 2 sequentially arranged at the lower end of suspension rod 1 from top to bottom, and two adjacent damping units 2 are connected by connecting rod 3;

[0043] The damping unit 2 includes a damping assembly 20 and a pair of inertial components 21 for cooperating with the damping assembly 20 to generate a damping force;

[0044] The middle section of the uppermost damping assembly 20 is connected to the lower end of the suspension rod 1, the middle sections of the two adjacent damping assemblies 20 are connected through the connecting rod 3, and a pair of inertial components 21 are sleeved on both ends of the damping unit 2 respectively. .

[0045] The suspension rod 1 of the present invention is used to suspend the present invention on the building. When the building is sub...

Embodiment 2

[0048] see Figures 2 to 7 As shown, the embodiment of the present invention provides a suspension damping device. The difference from Embodiment 1 is that the damping assembly 20 includes: a housing 200, a rotating shaft 201, a pair of magnetoelectric generating units 202 and a rotating magneto-rheological damping unit 203;

[0049] Both the magnetoelectric generating unit 202 and the rotating magneto-rheological damping unit 203 are located inside the housing 200, and the rotating magneto-rheological damping unit 203 is located between a pair of magneto-rheological generating units 202;

Abstract

The invention discloses a suspension shock absorbing device, which relates to the technical field of shock absorbing devices, comprising: a suspension rod and a plurality of damping units sequentially arranged at the lower end of the suspension rod from top to bottom; They are all connected by connecting rods; the damping unit includes a damping assembly and a pair of inertial components used to cooperate with the damping assembly to generate damping force; the middle section of the uppermost damping assembly is connected to the lower end of the suspension rod, and the two adjacent damping assemblies The middle sections of the damping unit are connected by connecting rods, and a pair of inertial components are respectively sleeved at both ends of the damping unit. The invention can not be affected by the installation area and space, can reduce the impact force of the building, and help the building maintain the stability of the internal structure.

Description

technical field [0001] The invention relates to the technical field of shock absorbing devices, in particular to a suspension shock absorbing device. Background technique [0002] The damage of high-rise building structures and bridges due to earthquake or wind load excitation will cause casualties and direct or indirect serious economic losses. The traditional methods to ensure the safety and normal use of structures such as buildings and bridges are mostly to Suspension shock absorbers in buildings or bridge structures; [0003] The traditional suspension device adopts a first-order consolidated single structure, which mainly uses the swing energy of the suspension mass, but the limited space and its passive control characteristics lead to poor control effect, which has become the main factor limiting its application. Contents of the invention [0004] In view of the defects existing in the prior art, the object of the present invention is to provide a suspension shock ...
