[0027] As shown in Figure 1 , Figure 2 , Figure 3 A train display bottom plate with an anti-vibration structure is provided in the embodiments of the present application, which comprises a horizontal mounting plate 1, a vertical mounting plate 2 is arranged at the front side of the horizontal mounting plate 1, a damping assembly is arranged at the front side of the vertical mounting plate 2, the damping assembly comprises: damping plates 201 and damping blocks 202, two damping plates 201 are symmetrically arranged at the two sides of the front end of the vertical mounting plate 2, the side wall of the damping plate 201 is provided with a groove, two damping blocks 202 are respectively arranged at the two ends of the opening part of the groove of the side wall of the damping plate 201, and a display mounting seat 3 is connected to the front side of the damping plate 201.
[0028] A plurality of mounting holes arranged at equal intervals are arranged on the horizontal mounting plate 1, which are used for mounting bolts so as to mount the horizontal mounting plate 1 on a train, in actual use, a display screen is mounted on the display mounting seat 3 through screws, and through the organic cooperation of the damping plate 201 and the damping block 202, the energy of vibration is absorbed and attenuated, so as to maintain the stability of the display mounting seat 3 and achieve an anti-vibration effect.
[0029] The damping plate 201 is designed in a split type and is respectively located at the two sides of the vertical mounting plate 2, the damping plate 201 has the ability of deformation, the groove arranged on the side wall of the damping plate 201 prolongs the path of vibration conduction and increases the time of vibration conduction, so as to consume the energy of vibration force and achieve an anti-vibration effect.
[0030] The damping block 202 is further arranged in the groove of the side wall of the damping plate 201, the damping block 202 is preferably made of high molecular foaming material, the vibration of the damping plate 201 is attenuated through the damping block 202, the conduction path of vibration force is destroyed, the damping block 202 also has a damping characteristic, can absorb and attenuate the energy of vibration, and achieves an anti-vibration effect.
[0031] In the embodiments, as shown in Figures 2-4As shown, the damping plate 201 is a U-shaped plate;
[0032] Shock-absorbing plates 201 are installed at the four corners of the front side of the vertical mounting plate 2;
[0033] The bending part of the damping plate 201 has an arc-shaped surface. When the vibration force is precisely applied to the flat surface of the damping plate 201, the vibration force will be concentrated at the bending part of the damping plate 201. Its originally stable arc-shaped structure will quickly undergo significant deformation. This deformation is usually manifested as the two flat parts of the damping plate 201 moving closer to each other, and the bending part bending further. Through its own geometric deformation, it achieves the storage and release of energy, thereby absorbing and weakening the vibration.
[0034] Meanwhile, the damping plates 201 are dispersed to optimize the stress structure, dispersing the concentrated force to a larger area and connection points, thereby protecting the main structure and improving overall stability.
[0035] The damping plate 201 has an opening facing the outside of the vertical mounting plate 2. The damping plate 201 includes a bent portion and straight portions located at both ends of the bent portion. The end corners of the straight portions of the damping plate 201 are flush with the end corners of the vertical mounting plate 2.
[0036] The geometric deformation of the damping plate 201 can be suppressed by the damping block 202. When the damping block 202 is made of rubber, it can assist in shock absorption and buffering. Through its internal elastic material and structural design, it converts impact energy into elastic potential energy, thereby reducing the direct damage to the display screen. Furthermore, the nonlinear elastic characteristics of the damping block 202 allow it to absorb and disperse energy through deformation and recovery when subjected to impact or vibration. This results in high internal resistance and significant damping, effectively reducing vibration transmission and noise. This excellent shock absorption effect helps improve the stability and reliability of the display screen. The damping block 202 can also adapt well to the dimensions of the damping plate 201, including maintaining its shape after deformation of the damping plate 201, demonstrating good stability.
[0037] A connector 203 is provided between two vertical damping plates 201, and the connector 203 is connected to the straight part of the damping plate 201;
[0038] The damping plates 201 are connected into a whole by connectors 203, which strengthens the mechanical structure, facilitates the dispersion of vibration force, and enhances the seismic resistance.
[0039] An anti-torsion member 204 is provided between two adjacent connectors 203, and the vertical projection of the anti-torsion member 204 is an "X" shape;
[0040] The anti-torsion component 204 can enhance the anti-torsion performance of the mechanical structure, prevent structural deformation or damage caused by excessive torque, and at the same time facilitate the dispersion of force. In addition, it has a cross structure, which can further disperse the vibration force. Moreover, the dispersion direction is different from that of the damping plate 201, thereby effectively attenuating the vibration force and achieving the anti-vibration effect.
[0041] Furthermore, the anti-torsion component 204 can provide support for the connector 203. When the two connectors 203 approach each other, the elasticity of the anti-torsion component 204 allows it to absorb and disperse energy through deformation and recovery, thereby achieving an anti-seismic effect.
[0042] The anti-torsion component 204 is fitted to the bent portion of the damping plate 201;
[0043] The anti-torsion component 204, the connector 203 and the damping plate 201 are all made of carbon fiber cloth that has been cut and integrally heat-pressed and cured.
[0044] The anti-torsion component 204 is attached to the damping plate 201, which can transmit pressure, facilitate the dispersion of force, avoid stress concentration, and improve the stability of the overall structure.
[0045] The anti-torsion component 204, connector 203, and damping plate 201 are integrally molded, possessing good mechanical properties, lightweight and excellent elasticity, high strength, good stability, and resistance to corrosion, resulting in a long service life.
[0046] A vibration isolation block 301 is provided on the back of the display screen mounting base 3. The vibration isolation block 301 is located between two damping plates 201, and the other end of the vibration isolation block 301 abuts against the surface of the vertical mounting plate 2.
[0047] The vibration isolation block 301 further supports the display mounting base 3. The vibration isolation block 301 is made of rubber and has damping characteristics. When the vibration isolation block 301 is impacted by vibration and moves closer to the vertical mounting plate 2, its deformation spreads in all directions. Both sides of the vibration isolation block 301 are provided with damping plates 201, and the vibration isolation block 301 can transmit pressure to the damping plates 201.
[0048] It is worth mentioning that the distance between the two damping plates 201 is fixed, and the greater the pressure on the isolation block 301, the greater its deformation. The larger the contact area between the isolation block 201 and the damping plate 201, the better the pressure dispersion effect.
[0049] Furthermore, the vibration isolation block 301 is in contact with the bent part of the damping plate 201, and the damping plate 201 can provide good support for the vibration isolation block 301 to resist pressure.
