The four lower springs 32 are disposed two by two symmetrically with the axial direction of the sixth guide rail 26 as a symmetry line. When the damping table is at the zero position, the lower spring 32 is perpendicular to the axial direction of the sixth guide rail 26 in the horizontal direction and has tension.

The specific implementation method comprises the following steps: the panel 1 is fixedly connected with a protected structure, and the bottom plate 8 is fixedly connected with the ground or a non-protected structure. When the panel 1 drives the fifth guide rail 24, the damper bracket 28 and the fifth rotary damper 20 to reciprocate along the direction of the fifth guide rail 24, the fifth rack 22 is relatively stationary, so that the gear on the fifth rotary damper 20 generates rotary motion with the fifth rack 22 as a motion fulcrum. At this time, the gear on the fifth rotary damper 20 rotates the damper rotating shaft on the fifth rotary damper 20 to generate the damping torque. The damping torque is transmitted to the gear of the fifth rotary damper 20 through the damper rotating shaft of the fifth rotary damper 20, and the gear of the fifth rotary damper 20 converts the damping torque into a damping force with the fifth rack 22 as a reaction point, thereby weakening the movement tendency of the panel 5 and counteracting the external force. In this process, the four upper springs 30 symmetrically arranged two by two are simultaneously stretched when the panel 5 moves, and form a certain angle with the moving direction of the fifth guide rail 24, the elastic force provided by the upper springs 30 and the tension component perpendicular to the moving direction of the fifth guide rail 24 are mutually offset, and the tension components in the same moving direction as the fifth guide rail 24 are mutually overlapped, so as to generate restoring force to the panel 1.

When the panel 1 drives the sixth slider 27 and the sixth rack 23 to reciprocate along the direction of the sixth guide rail 25, the sixth rotary damper 21 is relatively stationary, the sixth rack 23 drives the gear on the sixth rotary damper 21 to rotate, and at this time, the gear on the sixth rotary damper 21 drives the damper rotating shaft on the sixth rotary damper 21 to rotate to generate the damping torque. The damping torque is transmitted to the gear of the sixth rotary damper 21 through the damper rotating shaft of the sixth rotary damper 21, and the gear of the sixth rotary damper 21 transmits the damping torque to the sixth rack 23 to be converted into the damping force, thereby reducing the movement tendency of the panel 5 and counteracting the external force. In this process, the four lower springs 32 symmetrically arranged in pairs are stretched simultaneously when the panel 5 moves, and form a certain angle with the moving direction of the sixth slider 27, the elastic force provided by the lower springs 32 and the tension component perpendicular to the moving direction of the sixth slider 27 cancel each other out, and the tension components in the same moving direction as the sixth slider 27 are superposed on each other, so as to generate restoring force to the panel 5.

The present invention is not limited to the above embodiments, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are included in the scope of the claims of the present invention which are filed as the application.
