[0093] As shown in Figure 3 , Figure 9 , Figure 10 , Figure 13 and Figure 14 , the lower damping and limiting assembly 13 is composed of two lower limiting brackets 1301, two lower limiting rings 1302, a lower limiting cone 1303, two lower rotary dampers 1304, a lower damper base 1305, a lower rack 1306 and a lower limiting ring connecting piece 1307.

[0094] The two groups of lower damping and limiting assemblies 13 are respectively installed on the two sides of the lower surface of the middle plate 2 along the X direction.

[0095] The lower limiting bracket 1301 has a vertical baffle e on which a round through hole g is processed. The lower limiting ring 1302 is composed of a plurality of layers of elastic circular rings and steel circular rings which are mutually superimposed into a circular ring body b. The lower limiting ring connecting piece 1307 has a round through hole h. The circular ring body b is fixedly installed on the lower limiting ring connecting piece 1307, and the inner circle of the circular ring body b is concentric with the round through hole h of the lower limiting ring connecting piece 1307.

[0096] Two said lower limit support 1301 symmetrically arranged along the X direction at both ends of the lower damping limit component 13, the lower limit support 1301 with the lower plane of the middle plate 2 is fixedly connected.

[0097] The lower damper base 1305 is mounted on the upper plane of the bottom plate 3 along the X direction, and two lower rotary dampers 1304 are installed side by side on the lower damper base 1305 along the X direction. The lower rotary damper 1304 is provided with an external gear b connected with the damping shaft b inside the upper rotary damper 1204. The external gear b drives the damping shaft b to rotate during rotation, thereby generating damping force.

[0098] The lower rack 1306 is fixedly installed on the lower guide rail mounting member b of the lower plane of the middle plate 2 along the X direction. The lower rack 1306 is engaged with the external gear b of the lower rotary damper 1304 to transmit power.

[0099] The lower limit cone 1303 is composed of an elastic cone b and a steel cylinder b. The elastic cone b is a conical body made of elastic material, which is installed at one end of the steel cylinder b. The other end of the steel cylinder b is installed on both sides of the lower damper base 1305 along the Y direction, and the elastic cone b is concentric with the lower limit ring 1302.

[0100] Working mechanism of embodiment 1:

[0101] The horizontal vibration control device mentioned in the patent sets a mass block on it to form a tuned mass damper TMD system. The face plate 1 is fixedly connected with the mass block, and the bottom plate 3 is fixedly connected with the structure.

[0102] The first-order X-direction vibration frequency of the structure (referred to as "first-order X-direction structure main frequency")

[0103] The first-order Y-direction vibration frequency of the structure (referred to as "first-order Y-direction structure main frequency")

[0104] The X-direction natural frequency of the TMD system is consistent with the first-order X-direction structure main frequency of the structure.

[0105] The Y-direction natural frequency a of the TMD system is consistent with the first-order Y-direction natural frequency b of the structure.

[0106] When the structure is subjected to wind vibration or earthquake action, the structure itself will vibrate in response to the vibration reaction of the structure. The vibration reaction of the structure is divided into X-direction vibration reaction and Y-direction vibration reaction.

[0107] The vibration component of the first-order Y-direction structure frequency is the largest in the Y-direction vibration response. At this time, the TMD system works under the excitation of the first-order Y-direction structure frequency, and the mass block reciprocates at the first-order Y-direction vibration frequency. In addition, the vibration component of the first-order X-direction structure frequency is the largest in the X-direction vibration response. At this time, the TMD system works under the excitation of the first-order X-direction structure frequency, and the mass block reciprocates at the first-order X-direction vibration frequency. In this process:

[0108] A, by Figure 3 As shown in the figure, if the mass block drives the panel 1 to move from the zero position to the negative Y direction, the vertical baffle c on the panel 1 pushes the upper compression member 8 on the right side of the figure to move. Since the upper compression member 8 on the left side of the figure is supported by the vertical baffle a on the left side of the middle plate 2 through the upper buffer pad 16 on the left side of the figure, the panel 1 and the upper compression member 8 on the left side of the figure have Y-direction relative displacement through the upper slide rail group 6, and at the same time, the upper spring 10 is compressed to provide a restoring force to the panel 1.

[0109] At the same time, when the panel 1 moves in the negative Y direction, the upper rack 1206 also moves in the negative Y direction. Since the panel 1 and the middle plate 2 move relatively in the Y direction, the upper rack 1206 drives the outer gear a of the upper rotary damper 1204 to rotate, and the outer gear a drives the damping shaft a of the upper rotary damper 1204 to rotate, thereby generating damping force and dissipating energy.

[0110] B, as Figure 3 shown in the figure, the upper compression member 8 on the right side of the figure is driven by the restoring force of the upper spring 10 to move from the -Y position to the positive Y direction through the vertical baffle c. At this time, the panel 1 and the upper compression member 8 on the left side of the figure have Y-direction relative displacement through the upper slide rail group 6 on the left side of the figure, and at the same time, the upper compression member 8 on the right side of the figure is in contact with the upper buffer pad 16 on the right side of the figure and is supported by the vertical baffle a on the right side of the middle plate 2. At this time, the panel 1 returns to the zero position, and at the same time, the mass block continues to drive the panel 1 to move in the positive Y direction due to its own inertia.

[0111] The vertical baffle c on the panel 1 pushes the upper compression member 8 on the left side of the figure to move. Since the upper compression member 8 on the right side of the figure is supported by the vertical baffle a on the right side of the middle plate 2 through the upper buffer pad 16 on the right side of the figure, the panel 1 and the upper compression member 8 on the right side of the figure have Y-direction relative displacement through the upper slide rail group 6 on the right side of the figure, and at the same time, the upper spring 10 is compressed to provide a restoring force to the panel 1.

[0112] During the entire process of the panel 1 moving from the -Y zero position to the +Y position, the upper rack 1206 also moves in the positive Y direction. Since the panel 1 and the middle plate 2 move relatively in the Y direction, the upper rack 1206 drives the outer gear a of the upper rotary damper 1204 to rotate, and the outer gear a drives the damping shaft a of the upper rotary damper 1204 to rotate, thereby generating damping force and dissipating energy.

[0113] When the panel 1Y displacement value exceeds the preset value, the upper limit cone 1203 is inserted into the upper limit ring 1202, and the bottom diameter of the upper limit cone 1203 is greater than the diameter of the upper limit ring 1202, so the conical surface of the upper limit cone 1203 is in contact with the inner hole of the upper limit ring 1202. The material of the upper limit cone 1203 is elastomer, and the upper limit ring 1202 is a circular ring body a composed of multiple elastic rings and steel rings, so the upper limit cone 1203 and the upper limit ring 1202 form an elastic buffer zone. When the relative displacement between the panel 1 and the middle plate 2 continues to increase, the elastic cone of the upper limit cone 1203 passes through the upper limit ring connector 1207 and penetrates the vertical baffle b of the upper limit support 1201, and then the bottom surface of the elastic cone of the upper limit cone 1203 is clamped on the outside of the upper limit support 1201, realizing Y direction locking to prevent the displacement of the reset device in Y direction.

[0114] C、by Figure 4 As shown in the figure, the Y direction mechanism does not allow displacement in the X direction, so when the mass block drives the panel 1 to move from zero to negative in the X direction, it is equivalent to the mass block driving the middle plate 2 to move in the X direction. The vertical baffle d on the middle plate 2 pushes the lower compression member 9 on the right to move, and because the lower compression member 9 on the left is supported by the vertical baffle f on the left side of the bottom plate 3 through the lower buffer pad 17 on the left, the middle plate 2 and the lower compression member 9 on the left side move relative to each other in the Y direction through the lower slide rail group 7, and at the same time, the lower spring 11 is compressed, providing a restoring force to the middle plate 2.

[0115] At the same time, when the middle plate 2 moves in the X direction, it also drives the lower rack 1306 to move in the X direction, and because the middle plate 2 and the bottom plate 3 move relative to each other in the X direction, the lower rack 1306 drives the outer gear b of the lower rotary damper 1304 to rotate, and the outer gear b drives the damping shaft b of the lower rotary damper 1304 to rotate, thereby generating damping force and dissipating energy.

[0116] D、as Figure 5 As shown in the figure, the lower compression member 9 on the right is driven by the restoring force of the lower spring 11 to push the middle plate 2 to move from -X to positive in the X direction through the vertical baffle d, and at this time, the middle plate 2 and the lower compression member 9 on the left move relative to each other in the X direction through the lower slide rail group 7 on the left, until the lower compression member 9 on the right contacts the lower buffer pad 17 on the right and is supported by the vertical baffle f on the right side of the bottom plate 3, and at this time, the middle plate 2 returns to zero, and at the same time, the mass block continues to drive the middle plate 2 to move in the X direction due to its own inertia.

[0117] The vertical baffle d on the middle plate 2 pushes the lower compression member 9 on the left side of the figure to move. Since the lower compression member 9 on the right side of the figure is supported by the lower buffer pad 17 on the right side of the figure and the vertical baffle f on the right side of the figure, the middle plate 2 and the lower compression member 9 on the right side of the figure undergo relative displacement in the X direction through the lower slide rail group 7 on the right side of the figure. At the same time, the lower spring 11 is compressed, providing a restoring force to the middle plate 2.

[0118] During the entire process of the middle plate 2 moving from the -X zero position to the +X position, it also drives the lower rack 1306 to move in the X direction. Since the middle plate 2 and the bottom plate 3 move relative to each other in the X direction, the lower rack 1306 drives the external gear b of the lower rotary damper 1304. The external gear b drives the damping shaft b of the lower rotary damper 1304 to rotate, thereby generating damping force and dissipating energy.

[0119] When the displacement value of the middle plate in the X direction exceeds the preset value, the cone of the lower limit cone 1303 is inserted into the inner circle of the lower limit ring 1302. Since the bottom diameter of the lower limit cone 1303 is larger than the diameter of the inner hole of the lower limit ring 1302, the cone surface of the lower limit cone 1303 contacts the inner hole of the lower limit ring 1302. The lower limit cone 1303 is made of an elastic body, and the lower limit ring 1302 is composed of multiple layers of elastic rings and steel rings stacked together to form a ring body b. Therefore, the lower limit cone 1303 and the lower limit ring 1302 form an elastic buffer zone. As the relative displacement between the middle plate 2 and the bottom plate 3 continues to increase, the elastic cone of the lower limit cone 1303 passes through the lower limit ring connector 1307 and out of the vertical baffle e of the lower limit bracket 1301. Subsequently, the bottom surface of the elastic cone of the lower limit cone 1303 is locked on the outside of the lower limit bracket 1301 to achieve X-direction locking, so as to prevent the X-direction displacement of the reset device from being too large.

[0120] Example 2:

[0121] like Figure 17 As shown, multiple reset devices are arranged as needed, and a common mass block 18 is simultaneously fixedly connected to the panels 1 of the multiple reset devices. Under the effect of structural vibration, the common mass block 18 simultaneously drives the panels 1 of the multiple reset devices to move, absorbing and suppressing structural vibration while dissipating vibration energy. The working mechanism is the same as in Embodiment 1.
