As shown in fig. 2, in one embodiment, the first vibration damping unit 31 has a first installation plane 351, a first installation part is arranged on the first installation plane 351, the supporting leg 11 of the seat 1 is connected with the first installation part through a first connecting piece 51, and the supporting leg 11 abuts against the first installation plane 351; the second vibration damping unit 32 has a second mounting plane 352, a second mounting member is provided on the second mounting plane 352, and the floor panel 2 is connected to the second mounting member by a second connecting member 52 and abuts against the second mounting plane 352.

In one embodiment, the first vibration damping unit 31 and the second vibration damping unit 32 are in a straight bar structure parallel to each other, the first mounting part is a mounting groove 361 arranged along the extending direction of the first vibration damping unit 31, and the second mounting part is a plurality of mounting holes 362 arranged along the extending direction of the second vibration damping unit 32. Preferably, the first connecting member 51 is a mounting bolt, the second connecting member 52 is a mounting screw, the mounting bolt is clamped in the mounting groove 361 to fix the supporting leg 11 of the seat 1, and the mounting screw is matched with the mounting hole 362 to fix the floor 2.

It is understood that, in the railway vehicle, the seats 1 in the same row are arranged in the lateral direction of the vehicle, and the first and second vibration damping units 31 and 32 in the strip structure in the present embodiment are arranged in the longitudinal direction of the vehicle, so that the first vibration damping unit 31 can connect the seats 1 in a plurality of rows, improving the efficiency of mounting the first vibration damping unit 31 to the seats 1. More importantly, the first vibration damping unit 31 of the strip-shaped structure arranged along the longitudinal direction of the vehicle is provided with a longitudinal installation groove 361, the installation groove 361 is a sliding groove and can be directly connected with the seat 1, and the installation efficiency is improved. Because in the conventional vehicle interior, a sliding groove is additionally arranged on the shock absorber, and the seat 1 is connected through the sliding groove, in the embodiment, the upper end of the first shock absorbing unit 31 is provided with the mounting groove 361, and the arrangement direction and the position of the mounting groove 361 are consistent with those of the conventional sliding groove, so that the shock absorbing device 3 completely replaces the sliding groove, the seat 1 can be directly mounted on the shock absorbing device 3 through bolts, the installation of a transition sliding groove between the shock absorbing element and the seat 1 is avoided, and the mounting efficiency is improved.

When installed, as shown in fig. 4, the support leg 11 of the seat 1 is directly installed on the installation groove 361 by the installation bolt, and the bottom of the support leg 11 is in contact with and supported by the first installation plane 351. The mounting groove 361 enables the seat 1 to slide along the interior of the seat 1, so that the position of the seat 1 in the vehicle can be conveniently adjusted, the mounting groove 361 and the vibration damper 3 are integrated, the vibration damping performance and the structural installation are integrated, an independent sliding groove structure is saved, and the installation efficiency is improved.

In one embodiment, as shown in fig. 2, the first damping unit 31 and the second damping unit 32 are connected at one end to form an integrated base 37, the base 37 forms the first damping unit 31 and the second damping unit 32 into a complete structure, and the bottom surface of the base 37 is flat for easy installation on the frame 4. At the other ends of the first and second vibration damping units 31 and 32 are first and second installation planes 351 and 352, the first and second installation planes 351 and 352 facilitate the seating and attachment of the seat 1 and the interior floor 2, and ensure the smooth installation of the seat 1 and the floor 2.

In one embodiment, the lengths of the first and second vibration damping units 31 and 32 in the axial direction thereof are different, that is, the heights of the first and second vibration damping units 31 and 32 may be different, so that the first and second vibration damping units 31 and 32 having different heights form a stepped structure. Damping device 3 is stair structure, and its mounting plane of difference corresponds and connects seat 1 and floor 2, can adapt to the condition that the mounting height demand on seat 1 and floor 2 differs like this. Generally, it is necessary to make the installation groove 361 higher than the floor 2, and therefore, the first damping unit 31 is higher than the second damping unit 32, so that the floor 2 is installed on the lower second damping unit 32, and the seat 1 can be conveniently installed on the installation groove 361.

It should be noted that, if the first vibration damping unit 31 and the second vibration damping unit 32 are made of the same material and have the same shape and structure, the height difference between the first vibration damping unit 31 and the second vibration damping unit 32 naturally causes the first vibration damping unit 31 and the second vibration damping unit 32 to have different vibration damping forces, so that the different elastic supports can be realized by controlling the height of the first vibration damping unit 31 and the height of the second vibration damping unit 32. Further, the first vibration damping unit 31 and the second vibration damping unit 32 may be made of different materials so that they have different vibration damping forces, thereby achieving different vibration damping efficiencies for the seat 1 and the floor 2. It is worth mentioning that the interior of the vehicle compartment is generally divided into a seat side and a walkway side, and the pressure to which the seat side and the walkway side are subjected is generally different, so that the seat side and the walkway side in the vehicle compartment have different floors, respectively, as shown in fig. 1 and 5, and the floor 2 is divided into a walkway side floor 21 and a seat side floor 22, and the present invention provides a second embodiment of the vibration damping device 3 in order to satisfy vibration damping support for different built-in structures.

The first damping unit 31 is located between two second damping units 32, and the first damping unit 31 is higher than the two second damping units 32.

Like this, damping device 3 has just realized seat 1, pavement side floor 21 and seat side floor 22's simultaneous damping installation through three damping unit, and the bearing that three damping unit received can not mutual interference, and vibration between the three can not transmit each other, has realized seat 1, pavement side floor 21 and the independent damping installation of seat side floor 22, has satisfied seat 1, pavement side floor 21 and seat side floor 22 and has needed the demand of different support rigidity, has improved seat 1 and floor 2's damping efficiency.

The second embodiment provided by the vibration damping device 3 is applied to the intersection of the carriage seat 1 and the walkway, where the walkway side floor 21 and the seat side floor 22 meet, and where the support legs 11 of the outside of the seat 1 are provided, and further, since the support legs 11 of the outside of the seat 1 are generally installed between the walkway side floor 21 and the seat side floor 22, the second embodiment provided by the vibration damping device 3 satisfies the vibration damping support of the outside support legs of the seat 1 and the ends of the walkway side floor 21 and the seat side floor 22. The combined application of the first embodiment and the second embodiment provided by the vibration damping device 3 realizes effective vibration damping installation of the vehicle interior structure, meets the requirements of different support rigidity of the seat 1 and the floor 2, and improves the vibration damping efficiency of the seat 1 and the floor 2, thereby improving the riding comfort.
