[0083] The following is described in conjunction with specific embodiments.

[0084] Embodiment 1

[0085] A multi-directional vibration damping device, as shown in Figure 1 and 2 , comprising:

[0086] A gear mechanism 1 comprising a first gear 11, a second gear 12 inside the first gear 11 and meshing with it, and a plurality of damping particles 121 arranged inside the second gear 12;

[0087] A metal conductor double crank mechanism 2 connected with the gear mechanism 1 and making the second gear 12 rotate around the first gear 11;

[0088] A plurality of connecting rods 3 connected with the metal conductor double crank mechanism 2 and connected with the structure 6 to be damped;

[0089] An outer cavity 4 located outside the gear mechanism 1 and the metal conductor double crank mechanism 2;

[0090] And a magnet 5 installed on the inner wall of the outer cavity 4 and located on both sides of the plane where the metal conductor double crank mechanism 2 is located.

[0091] In this embodiment, the metal conductor double crank mechanism 2 comprises:

[0092] Two racks 21 connected on both sides of the first gear 11 and located on the same straight line;

[0093] Two metal conductor cranks 22 rotating away from one end of the inner meshing gear 1 around the two racks 21;

[0094] And a connecting rod 23 connected with the two metal conductor cranks 22, the connecting rod 3 is connected with the connecting rod 23, and the second gear 12 is located on the connecting rod 23 and rotates with it.

[0095] In the embodiment, the lengths of the two metal conductor cranks 22 are equal, and the shapes of the two metal conductor cranks 22 are the same; the lengths of the two racks 21 are equal. The metal conductor crank 22 is linear; the rack 21 is linear; and the connecting rod 23 is linear.

[0096] In the embodiment, the material of the metal conductor crank 22 is copper.

[0097] In the embodiment, the second gear 12 is rotationally connected to the connecting rod 23 through the rotating shaft 13, and the second gear 12 is located in the middle of the connecting rod 23.

[0098] In the embodiment, two connecting rods 3 are provided, one end of each connecting rod 3 is rotationally connected to the structure 6 to be damped, and one end of each connecting rod 3 is rotationally connected to two ends of the connecting rod 23.

[0099] In the embodiment, the second gear 12 is internally provided with four cavities 122 which are hollow and used for placing the damping particles 121. Five damping particles 121 are arranged in each cavity 122.

[0100] In the embodiment, the particle size of the damping particles 121 is 25 mm, the shape of the damping particles 121 is a sphere, and the damping particles 121 are steel balls. The material of the cavity 122 is concrete. Through the collision of the damping particles 121 and the cavity 122 made of different materials, the energy loss in the collision process can be increased.

[0101] In the embodiment, the magnet 5 includes a first magnet 51 and a second magnet 52 which are respectively located on two sides of the plane where the metal conductor double crank mechanism 2 is located. The first magnet 51 and the second magnet 52 have opposite magnetic pole polarities, and the magnetic field lines generated thereby are perpendicular to the plane where the metal conductor double crank mechanism 2 is located.

[0102] The working principle of the multi-directional damper in the embodiment is as follows:

[0103] When the structure 6 to be damped is subjected to horizontal load in the X direction, the horizontal load in the X direction is transmitted to the connecting rod 3, and then to the connecting rod 23, so that the connecting rod 23 moves in the X direction. When the vibration of the structure 6 to be damped is low frequency vibration, the rack 21 and the first gear 11 remain substantially stationary, so that the two metal conductor cranks 22 rotate synchronously around the end points of the two racks 21, the second gear 12 rotates around the first gear 11, and the damping particles 121 in the cavity 122 of the second gear 12 collide to dissipate energy. At the same time, the metal conductor cranks 22 cut the magnetic induction lines generated by the magnet 5 to dissipate energy. However, due to the small vibration, the speed of the metal conductor cranks 22 cutting the magnetic induction lines is slow, and the energy dissipation of the magnetic induction lines is small, mainly through the collision of the damping particles 121.

[0104] When the structure 6 to be damped is subjected to horizontal load in the X direction, the horizontal load in the X direction is transmitted to the connecting rod 3, and then to the connecting rod 23, so that the connecting rod 23 moves in the X direction. When the vibration of the structure 6 to be damped is low frequency vibration, the rack 21 and the first gear 11 remain substantially stationary, so that the two metal conductor cranks 22 rotate synchronously around the end points of the two racks 21, the second gear 12 rotates around the first gear 11, and the damping particles 121 in the cavity 122 of the second gear 12 collide to dissipate energy. At the same time, the metal conductor cranks 22 cut the magnetic induction lines generated by the magnet 5 to dissipate energy. However, due to the small vibration, the speed of the metal conductor cranks 22 cutting the magnetic induction lines is slow, and the energy dissipation of the magnetic induction lines is small, mainly through the collision of the damping particles 121.

[0105] When the structure 6 to be damped is subjected to a load in the Z direction, the damping particles 121 inside the second gear 12 collide and dissipate energy during movement in the Z direction. At the same time, the horizontal load in the Z direction is transmitted to the connecting rod 3, and then to the connecting rod 23 and the metal conductor crank 22. When the structure 6 to be damped is subjected to low-frequency vibration, the frame 21 and the first gear 11 remain substantially stationary, causing the two metal conductor cranks 22 to rotate synchronously around the end points of the two frames 21, causing the second gear 12 to rotate around the first gear 11, and causing the damping particles 121 inside the cavity 122 of the second gear 12 to collide and dissipate energy. At the same time, the metal conductor cranks 22 cut the magnetic induction lines generated by the magnet 5 to dissipate energy, but due to the small vibration, the metal conductor cranks 22 cut the magnetic induction lines at a slow speed, and the magnetic induction lines dissipate less energy, mainly through the collision of the damping particles 121.

[0106] When the structure 6 to be damped is subjected to a load in the Z direction, the damping particles 121 inside the second gear 12 collide and dissipate energy during movement in the Z direction. At the same time, the horizontal load in the Z direction is transmitted to the connecting rod 3, and then to the connecting rod 23 and the metal conductor crank 22. When the structure 6 to be damped is subjected to low-frequency vibration, the frame 21 and the first gear 11 remain substantially stationary, causing the two metal conductor cranks 22 to rotate synchronously around the end points of the two frames 21, causing the second gear 12 to rotate around the first gear 11, and causing the damping particles 121 inside the cavity 122 of the second gear 12 to collide and dissipate energy. At the same time, the metal conductor cranks 22 cut the magnetic induction lines generated by the magnet 5 to dissipate energy, but due to the small vibration, the metal conductor cranks 22 cut the magnetic induction lines at a slow speed, and the magnetic induction lines dissipate less energy, mainly through the collision of the damping particles 121.

[0107] Example 2

[0108] As Figure 3 and 4 shown, most of them are the same as in Example 1, except that:

[0109] In this embodiment, the metal conductor crank 22 is connected to the frame 21 at one end and is provided with a damping ball 7 connected by a rope 71. When subjected to a horizontal load in the Y direction, the damping ball 7 connected by the rope 71 collides with the outer cavity 4 to dissipate energy.

[0110] In the embodiment, the particle size of the damping ball 7 is 20-50 mm.

[0111] In the embodiment, the damping ball 7 is a steel ball.

[0112] The working principle of the multidirectional damper in the embodiment is as follows:

[0113] The multidirectional damper in the embodiment is subjected to the load in the X direction and the Z direction, which is consistent with the embodiment 1. When the structure to be damped 6 is subjected to the load in the Y direction, the load in the Y direction is transmitted to the connecting rod 3, and then transmitted to the damping ball 7 through the metal conductor crank 22 and the rope 71, so that the damping ball 7 collides with the outer cavity 4 to dissipate energy.

[0114] Embodiment 3

[0115] Compared with the embodiment 2, most of them are the same, except that:

[0116] In the embodiment, the particle size of the damping particles 121 inside each cavity 122 is different, and the shape is different. The particle size of the damping particles 121 is 5-50 mm, and the shape of the damping particles 121 is a sphere or a block. The damping particles 121 are a steel ball, a concrete ball, a glass block, and a ceramic block. The glass block and the ceramic block are cubes. The collision of the traditional single shape and single particle size is changed to the collision between different shapes and different particle sizes, which is more conducive to energy loss in the collision process. The material of the cavity 122 is concrete. Through the collision of the damping particles 121 and the cavity 122 made of different materials, the energy loss in the collision process can be increased.

[0117] The above description of the embodiments is for the convenience of the ordinary skilled person in the technical field to understand and use the utility model. Those skilled in the art can easily make various modifications to these embodiments, and apply the general principles described herein to other embodiments without creative labor. Therefore, the utility model is not limited to the above embodiments, and those skilled in the art can make improvements and modifications within the scope of the utility model without departing from the scope of the utility model.
