[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] See also Figure 1 The utility model provides a technical solution: a vibration-damping base, comprising a vibration-damping base body 1, having a planar top 2, with support parts 3 and a planar bottom 4 connected to both sides of the top 2 in sequence. The support part 3 is "S" shaped, and the middle is hollowed out to reduce the weight of the vibration-damping base body 1. A reinforcing rib 5 is provided between the two support parts 3, and the reinforcing rib 5 is located near the bottom 4. A through circular hole 6 is provided in the center of the top 2. The vibration-damping base body 1 is made of a vibration-damping alloy.

[0029] Vibration-suppressing alloy is a damping alloy material that has the same damping properties as rubber while having the strength of structural steel. The principle is that when encountering external force, twins will be generated. As the external force increases, the twins will grow and expand, and new twins will continue to form. The cyclic motion of these twins largely offsets the external force, converting mechanical energy into heat energy to consume energy, thereby achieving the effect of vibration suppression.

[0030] Embodiment 2

[0031] See also Figure 1-4 Based on the vibration-damping base of the above-mentioned embodiment 1, the utility model also provides a technical solution: a seat anti-pullout structure with a vibration-damping base, which is composed of the vibration-damping base body 1 of the above-mentioned embodiment 1, a seat connecting piece 7, a cylindrical piece 8 and a threaded column 9.

[0032] The seat connecting member 7 is a flat plate made of aluminum alloy, with a connecting hole 1 in the middle and seat mounting holes on both sides.

[0033] The upper surface of the cylindrical member 8 is larger than the circular hole 6 in the center of the top 2. The upper surface of the cylindrical member 8 is flat, and a connecting hole 2 is provided in the center. A protective cover 10 is provided on the outer surface of the cylindrical member 8. Preferably, the protective cover 10 is made of rubber material to prevent the cylindrical member 8 from being damaged.

[0034] The threaded column 9 is preferably a threaded steel column, which is connected to the connection hole 1 of the seat connecting part 7, passes through the circular hole 6 of the vibration-damping base, and is connected to the connection hole 2 of the cylindrical part 8, so as to fix the seat connecting part 7, the vibration-damping base body 1 and the cylindrical part 8 in sequence, and the lower surface of the seat connecting part 7 fits with the upper surface of the top 2, and the lower surface of the top 2 fits with the upper surface of the cylindrical part 8.

[0035] Working principle:

[0036] The vibration-damping base body 1 adopts an "S"-shaped support part 3, which can distribute pressure and stress more evenly when bearing heavy loads, reduce stress concentration points, and improve the durability and stability of the structure. At the same time, the middle of the "S"-shaped support part 3 is hollowed out to reduce the weight, and the integrated structural design reduces assembly time.

[0037] The seat and the seat connector 7 are fixed through the seat mounting hole, the vibration-damping base body 1 is connected to the car, airplane or high-speed rail, etc., and the bottom 4 of the plane of the vibration-damping base body 1 fits with the car, airplane or high-speed rail, etc. When the car, airplane or high-speed rail moves and vibrates, the vibration-damping base body 1 is subjected to external force, and twins are generated inside the vibration-damping base body 1. As the external force increases, the twins grow and expand, and new twins are continuously formed. The cyclic motion of these twins offsets the external force, reducing the vibration transmitted from the vibration-damping base body 1 to the seat.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
