Referring to fig. 1 to 4, the present application provides a vibration damping device 10 for a device to be damped (not shown) including a vibrating member and a structural member connected to the vibrating member. The vibration part refers to a source of vibration in the equipment to be damped, and the structural part refers to a structure which needs to reduce the vibration due to connection with the vibration part in the equipment to be damped. The damping device 10 comprises a first bushing 11, a second bushing 12 and a support 13 for connection with the equipment to be damped. The support 13 may be a cast aluminum material. The first bushing 11 is connected to a support 13, wherein the number of the first bushing 11 may be plural. The connection of the first bushing 11 and the support 13 may mean that the first bushing 11 is connected inside the support 13, or that the first bushing 11 is connected outside the support 13. The first bushing 11 includes a first elastic member 14 for connection with one of the vibrating member and the structural member. The first elastic member 14 has elasticity, and the material of the first elastic member 14 may be an elastic material such as rubber. The second bushing 12 is connected with a support 13. Wherein the number of the second bushings 12 may be plural. The connection of the second bushing 12 to the support 13 may mean that the second bushing 12 is connected inside the support 13, or that the second bushing 12 is connected outside the support 13. The second bushing 12 includes a second elastic member 15 for connection with the other one of the vibrating member and the structural member. The second elastic member 15 has elasticity, and the material of the second elastic member 15 may be an elastic material such as rubber, which is not limited in this application. Wherein the first elastic member 14 may be used for connection with the vibrating member, and the second elastic member 15 may be used for connection with the structural member. It is also possible that the first elastic member 14 is used for connection with the structural member and the second elastic member 15 is used for connection with the vibrating member. Because the first elastic part 14 and the second elastic part 15 have elasticity, the vibration generated by the vibrating part is transmitted to the structural part after the vibration damping effect of the first elastic part 14 and the second elastic part 15, so that the vibration generated by the vibrating part can be absorbed through the first elastic part 14 and the second elastic part 15, the vibration of the structural part is weakened, and the vibration damping effect is better. In this embodiment, the first elastic member 14 is used to be coupled to the vibration member, and the second elastic member 15 is used to be coupled to the structural member. This arrangement allows the vibration generated by the vibrating member to be absorbed by the first elastic member 14 and the second elastic member 15 in turn. Wherein the volume of the first elastic member 14 is larger than the volume of the second elastic member 15. It will be appreciated that the volume of the first elastic element 14 is greater than the volume of the second elastic element 15, meaning that the first elastic element 14 absorbs vibrations better than the second elastic element 15. Since the first elastic member 14 is connected to the vibration member, the vibration of the supporting member 13 can be reduced, the service life of the supporting member 13 can be prolonged, and the noise during the transmission can be reduced.

The first elastic member 14 and the second elastic member 15 are disposed at different positions and at a distance such that the vibration is transmitted at a longer distance, thereby reducing the vibration transmitted to the structural member. In the present embodiment, the first direction 90 is perpendicular to the second direction 91. The first elastic member 14 is disposed at a position distant from the second elastic member 15, and when the vibrating member vibrates, the first elastic member 14 has a better damping effect in a direction perpendicular to the first direction 90, and the second elastic member 15 has a better damping effect in a direction perpendicular to the second direction 91. The arrangement of the first elastic member 14 and the second elastic member 15 at the same time can absorb vibration in all directions, so that the damping effect of the damping device 10 is better. In this embodiment, the supporting member 13 includes a first supporting member 17 extending along the second direction 91 and a second supporting member 18 extending along the first direction 90, and the first supporting member 17 is connected to the second supporting member 18.
