Specifically, the fixing part 410 is empty and has a predetermined length so as to be covered on the upper end of the lamp column. Although the drawing shows a cylindrical shape erected in a vertical direction, it is obvious that the shape can be changed to correspond to the shape of the upper end of the lamp column, and it is safe to fix it by forced press fitting, but additional bolts are used for more reliable fixation. It is also possible to do.

For example, as shown in FIGS. 3 and 4, when two vibration reducing units are provided, the first vibration reducing unit 420 and the second vibration reducing unit 430 may be configured with a predetermined distance apart in the vertical direction. , At this time, it is preferable that the first vibration reducing unit 420 and the second vibration reducing unit 430 are arranged to be orthogonal to each other, that is, perpendicular to each other. This is for the purpose of stably reducing vibration regardless of the direction of vibration transmitted to the lamp column. to be.

Next, the first vibration reducing unit 420 and the second vibration reducing unit 430 will be described in detail.

First, the first vibration reducing unit 420 includes a first cylindrical portion 421, a pair of first cap portions 422, a first support shaft 423, and a first mass body 424.

The first cylindrical portion 421 is empty inside to accommodate the first mass 424 and is positioned in a horizontal direction while being parallel to the ground. A pair of first cap portions 422 are provided at both ends of the first cylindrical portion 421 to prevent separation of the first mass body 424 and at the same time to induce an electrical repulsive force to the first mass body 424. , The first 1-1 polar body 422 ′ is provided inside the first cap part 422.

The first support shaft 423 is a cylindrical or polygonal shape having a predetermined thickness to connect the pair of first cap portions 422 to each other, and the first mass body 424 is a first support shaft 423 along the first support shaft 423.

And a first cover 424(b) connecting the 1-2nd polar body 424(a) and the pair of 1-2nd polar body 424(a) to each other.

Although not shown in the drawings, the inner space of the first cover 424(b) may be filled with the same material or different materials may be filled in consideration of the required mass of the mass.

In addition, the above-described 1-1 polar body 422 ′ and 1-2 polar body 424 (a) have the same polarity, for example, the 1-1 polar body 422 ′, so that electric repulsion force occurs with each other. In the case of a negative electrode, the 1-2nd polar body 424(a) is also a negative electrode. On the contrary, when the 1-1st polar body 422' is an anode, the 1-2nd polar body 424(a) is also a positive electrode. to be.

Of course, the 1-2nd polar body 424(a) does not necessarily have to have one polarity. That is, although one side may be an anode and the other side may be a cathode, the polarity must be the same as that of the 1-1st polar body 422' so that the repulsive force acts in a direction facing each other with the 1-1st polar body 422'.

Briefly explaining the principle of vibration reduction by the first vibration reduction unit 420 having the above configuration, when an external force is applied from one direction when the first cylinder part 421 is referenced, the upper end of the lamp column is bent, 1 The mass body 424 moves in the same direction by inertia, but moves in the opposite direction by electrical repulsive force, so that the lampshade returns to its original position in a short time.

FIG. 6 is a perspective view showing the vibration reduction window shown in FIG. 3 cut along line B-B'. The second vibration reducing unit 430 will be described with reference to FIG. 6. The second vibration reducing unit 430 is positioned above the first vibration reducing unit 420, and only the directions in which the second vibration reducing unit 420 is disposed are different, but the remaining configurations are substantially the same.

Specifically, the second vibration reducing unit 430 includes a second cylindrical portion 431, a pair of second cap portions 432, a second support shaft 433, and a second mass body 434.

The second cylindrical portion 431 is empty inside so as to accommodate the second mass body 434 and is positioned in a horizontal direction while being parallel to the ground, but is disposed orthogonal to the first vibration reducing portion 420.

A pair of second cap portions 432 are provided at both ends of the second cylindrical portion 431 to prevent separation of the second mass body 434 and at the same time induce an electrical repulsive force to the second mass body 434. , A 2-1 polar body 432 ′ is provided inside the second cap part 432.

The second support shaft 433 is a cylindrical or polygonal shape having a predetermined thickness to connect the pair of second cap portions 432 to each other, and the second mass body 434 is a second support shaft 433 along the second support shaft 433. The cylindrical portion 431 is mounted to be slidable in the longitudinal direction.

That is, the second mass body 434 has the same polarity as the 2-1 polar body 432 ′ and has a pair of through holes formed in the center so as to be slidable along the second support shaft 433 with a predetermined distance apart. It is configured to include a 2-2 polar body 434 (a), and a second cover 434 (b) connecting the pair of the 2-2 polar body 434 (a) to each other.

Although not shown in the drawing, the inner space of the second cover 434(b) may be filled with the same material or different materials may be filled in consideration of the required mass of the mass.

In addition, the 2-1 polar body 432 ′ and the 2-2 polar body 434 (a) described above have the same polarity, for example, the 2-1 polar body 432 ′ so that electric repulsion is generated with each other. In the case of a negative electrode, the 2-2nd polar body 434(a) is also a negative electrode, whereas when the 2-1 polar body 432' is a positive electrode, the 2-2 polar body 434(a) is also a positive electrode. to be.

Of course, the 2-2 polar body 434(a) does not necessarily have to have one polarity. That is, one side may be an anode and the other side may be a cathode, but the polarity should be the same as that of the 2-1 polar body 432 ′ so that the repulsive force acts in a direction facing each other with the 2-1 polar body 432 ′.

Briefly explaining the principle of vibration reduction by the second vibration reduction unit 430 having the above configuration, when an external force is applied from one direction when the second cylinder part 431 is referenced, the upper end of the lamp column is bent, 2 The mass body 434 moves in the same direction by inertia, but moves in the opposite direction by electric repulsion, so that the headlamp returns to its original position in a short time.

In particular, since the second vibration reducing unit 430 is disposed to be orthogonal to each other, the direction in which the external force is applied can be more widely covered, and a vibration reducing unit having the above configuration is additionally provided. When provided, the vibration reduction effect can be further increased.

Meanwhile, the connection unit 440 is a configuration for connecting the first vibration reducing unit 420 and the second vibration reducing unit 430 described above to the fixing unit 410.
