[0025] Next, refer to Figures 1 to 3 to describe the self-resetting viscous damper of the embodiments of the present utility model.
[0026] The self-resetting viscous damper of the embodiments of the present utility model includes a cylinder body 100. A piston 300 is slidably arranged transversely in the cylinder body 100. A first connecting rod 200 is arranged on the left side of the piston 300, and the first connecting rod 200 penetrates through the left wall of the cylinder body 100 transversely; two reset components 400 are arranged in the cylinder body 100, and the two reset components 400 are respectively arranged on the left side and the right side of the piston 300. The reset component 400 includes an elastic member 410, and the elastic deformation direction of the elastic member 410 is transverse.
[0027] For example, as Figure 1 shown, the cylinder body 100 is in the shape of a horizontally arranged cylinder. End walls are arranged at both the left end and the right end of the cylinder body 100, and the two end walls are respectively called the left wall and the right wall. The left wall is provided with a first sliding hole for the first connecting rod 200 to pass through. A sealing ring can be arranged between the hole wall of the first sliding hole and the first connecting rod 200 for sealing. Damping oil is arranged in the cylinder body 100, and a piston 300 is arranged in the cylinder body 100. The outer diameter of the piston 300 is slightly smaller than the inner diameter of the cylinder body 100, or the piston 300 is provided with a transversely arranged through hole, so that the damping oil in the space on the left side of the piston 300 can communicate with the damping oil in the space on the right side of the piston 300; referring to Figure 2 , the right end of the first connecting rod 200 is fixedly connected to the piston 300, and the left end of the first connecting rod 200 passes through the first sliding hole, so that the first connecting rod 200 is slidably connected to the cylinder body 100 relatively.
[0028] By providing two reset components 400, when the damper extends or contracts to dissipate energy, the piston 300 moves left or right, compressing the elastic member 410 on the left or right side. After the damper dissipates energy, the elastic member 410 elastically recovers, pushing the piston 300 to move right or left, achieving the purpose of resetting the damper, greatly reducing the later maintenance and repair costs, and saving a large amount of manpower and financial resources for users.
[0029] In some embodiments of the present invention, the reset component 400 abuts against the piston 300. In this way, the damper has a relatively large stiffness, and the building will not deform during slight vibrations, maintaining the stability of the building.
[0030] In some embodiments of the present invention, a first gap is provided between the reset component 400 and the piston 300. In this way, when the vibration is slight and the deformation amplitude of the building is small, the piston 300 does not contact the reset component 400, and the stiffness of the damper is small, and the damper can dissipate the vibration energy; when the vibration is large and the deformation amplitude of the building is large, the piston 300 abuts against the reset component 400, and the stiffness of the damper is large, more effectively dissipating the vibration energy.
[0031] In some embodiments of the present invention, with reference to Figure 3 , the reset component 400 further includes two limiting members 420 and multiple cables 430. The two limiting members 420 are respectively abutted against the left end and the right end of the elastic member 410, and the cables 430 are connected between the two limiting members 420. It should be noted that if the two elastic members 410 are directly connected to the piston 300, when the piston 300 moves left or right, both of the two elastic members 410 need to deform, and the fatigue loss of the two elastic members 410 is relatively large, and the service life is relatively short; in this embodiment, by providing two limiting members 420 and multiple cables 430, when the piston 300 moves left, only the elastic member 410 on the left side deforms, and the elastic member 410 on the right side does not need to deform; when the piston 300 moves right, only the elastic member 410 on the right side deforms, and the elastic member 410 on the left side does not need to deform, which is beneficial to reducing the fatigue loss of the elastic member 410 and improving the service life.
[0032] In some embodiments of the present invention, the cable 430 is a steel cable. In this way, the cable 430 can bear a large force and is not easily damaged.
[0033] In some embodiments of the present utility model, the reset assembly 400 located on the left side is referred to as the left assembly. The limiting member 420 of the left assembly is annular and sleeved on the first connecting rod 200. The inner diameter of the limiting member 420 is larger than the diameter of the first connecting rod 200, enabling the first connecting rod 200 to move laterally relative to the limiting member 420. A plurality of cables 430 are uniformly arranged along the circumferential direction of the limiting member 420, and the number of cables 430 contained in each reset assembly 400 can be four. In this way, the force on the limiting member 420 is balanced and the structure is stable.
[0034] In some embodiments of the present utility model, the elastic member 410 of the left assembly is a spring and is sleeved on the first connecting rod 200. The inner diameter of the spring is larger than the diameter of the first connecting rod 200, such that the spring does not interfere with the lateral movement of the first connecting rod 200; in this way, the structure is simple and convenient to arrange.
[0035] In some embodiments of the present utility model, the two reset assemblies 400 are mirror-symmetrical in a left-right structure. In this way, there is no need to independently design the two reset assemblies 400, and only one type of reset assembly 400 needs to be manufactured during production and manufacturing, which is convenient for the production of the damper.
[0036] In some embodiments of the present utility model, a second connecting ring 110 is provided at the right end of the cylinder block 100. This facilitates the installation of the cylinder block 100 to a building.
[0037] In some embodiments of the present utility model, a first connecting ring 210 is provided at the left end of the first connecting rod 200. This facilitates the installation of the first connecting rod 200 to a building.
[0038] The above has specifically described the preferred embodiments of the present utility model, but the present utility model is not limited to the embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
