Detailed Description

The following detailed description of preferred embodiments of the invention refers to the accompanying drawings.

Fig. 1 shows a schematic perspective view of a damping device 100 according to a preferred embodiment of the present invention, and referring to fig. 4, the damping device 100 includes an upper shell 11 and a lower shell 12 fixedly connected to form a damping housing 10. A fastening member 30 for attaching the attachment 300 is provided on the vibration-damping housing 10. The vibration damping housing 10 is provided with a stud 20, first and second

vibration damping rubbers

40 and 50, and a disc table 21 which is located between the first and second

vibration damping rubbers

40 and 50 and is fixedly connected to the stud 20.

When the vibration damping device 100 receives multi-directional vibration (such as X-axis direction, Y-axis direction, Z-axis direction, etc.) from the attachment 300, the first vibration damping rubber 40 and the second vibration damping rubber 50 generate shearing and compression deformation according to the direction of the vibration force, and the vibration is reduced and then transmitted to the lamp 200 through the coil base 21 and the stud 20, so that the external vibration impact force applied to the lamp 200 can be reduced.

Fig. 2 shows a stepped cross-sectional view of the damping device 100 along line a-a in fig. 1, and referring to fig. 4, a stud 20 is disposed in the damping housing 10, and an upper end of the stud 20 penetrates through the upper housing 11 for connecting the lamp 200. The part of the stud 20 in the vibration damping shell 10 is sleeved with first vibration damping rubber 40, the lower end of the stud 20 is fixedly provided with a disc table 21 for supporting the first vibration damping rubber 40, the lower part of the disc table 21 is provided with second vibration damping rubber 50 in the vibration damping shell 10, and the disc table 21 is arranged between the first vibration damping rubber 40 and the second vibration damping rubber 50.

Fig. 3 shows an exploded structure of the damping device 100 of the present embodiment, and referring to fig. 2 and 4, the fastening member 30 includes a bolt 31 and a nut 32, and the upper shell 11 and the lower shell 12 are respectively provided with an upper shell fixing hole site 13 and a lower shell fixing hole site 14. The bolt 31 sequentially passes through the upper shell fixing hole site 13 and the lower shell fixing hole site 14 and is locked by the nut 32 at the end of the bolt 31, so as to fixedly connect the upper shell 11 and the lower shell 12 to form the damping shell 10, and the stud 20, the first damping rubber 40 and the second damping rubber 50 are compressed between the upper shell 11 and the lower shell 12. The disc table 21 at the lower end of the stud 20 is located between the first damper rubber 40 and the second damper rubber 50. By connecting the upper case 11 and the lower case 12 by the fastening member 30 for connecting the attachment 300, the number of parts of the vibration damping device 100 can be reduced, the vibration damping device 100 can be more simply constructed, and the cost can be saved.

As shown in fig. 3, it is preferable to provide the first vibration damping rubber 40 and the second vibration damping rubber 50 in the same structure; and the upper case 11 and the lower case 12 are configured in the same structure, so that they do not need to be distinguished during assembly, and the assembly process of the components of the vibration damping device 100 is simpler. The first damping rubber 40 and the second damping rubber 50 are preferably provided in a ring shape, and the central holes thereof are sized to fit the stud 20.

As shown in fig. 3 and also referring to fig. 2, one or more positioning protrusions 211 are provided on the tray table 21 to increase the friction between the tray table 21 and the first and

second damping rubbers

40 and 50, so as to better absorb and reduce vibration.

Because the first vibration damping rubber 40 and the second vibration damping rubber 50 have certain elasticity, when the upper shell 11 and the lower shell 12 are buckled and pressed on the first vibration damping rubber 40 and the second vibration damping rubber 50, the disc table 21 and the positioning lug 211 on the disc table 21 are locally sunk into the first vibration damping rubber 40 and the second vibration damping rubber 50, when the vibration damping device 100 is impacted or vibrated, the first vibration damping rubber 40 and the second vibration damping rubber 50 are sheared and compressed to deform, and after vibration absorption is reduced, the vibration is transmitted to the lamp 200 through the stud 20.

In addition, as shown in fig. 4 and 5 and also referring to fig. 1, the invention further provides a lamp 200 using the damping device 100, wherein a seat-type installation diagram of the damping device 100 and the lamp 300 is shown in fig. 4, and a suspension-type installation diagram is shown in fig. 5. In both of these mounting modes, the stud 20 is connected to the lamp 200 at the end extending out of the upper shell 11, and is connected to the attachment 300 by the fastener 30 fixedly connecting the upper shell 11 and the lower shell 12.

The vibration damping device 100 of the present invention has a simple structure and a small volume, and can be used alone or together with a lamp 200. As shown in fig. 5, two vibration dampers 100 may be used for suspension mounting, so that the fixing is more stable and the vibration-proof effect is better.

The vibration damping device 100 of the present invention can effectively solve the problem of multi-directional vibration damping of the lamp 200 by absorbing and damping multi-directional vibration from the attachment 300 by the first vibration damping rubber 40 and the second vibration damping rubber 50 and then transmitting the vibration to the lamp 200 through the stud 20.

By using the vibration damping device 100 of the invention, the vibration damping performance of the lamp 200 can be obviously improved, the service life of the lamp bulb of the lamp is prolonged, thereby avoiding the economic loss of customers caused by the damage of the bulb and saving the maintenance cost. The vibration damping device is simple in structure and low in production cost.

It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
