Description

Technical Field

[0001] The present application relates to the technical field of precision vibration reduction, and in particular to a vibration reduction device and a vibration reduction system. Background Art

[0002] Vibration damping systems comprising helical springs, which are mainly in the form of steel springs, are already known. In such systems, the load to be isolated from the ground is mounted on three or more dampers, which contain helical springs that are effective at least in the vertical direction. Furthermore, the damping effect of the vibration damping system can be increased by configuring it as an active vibration damping system. In an active vibration damping system, sensors are arranged on the load to be damped and / or on the ground and at least one actuator is controlled via a control loop, which actuator actively counteracts the vibrations. In particular, contactless actuators are used as actuators, in particular actuators based on the Lorentz principle.

[0003] However, in active vibration reduction systems, the helical springs generate torque during floating, which in turn induces horizontal forces, which usually lead to horizontal displacement or twisting of the load, which is undesirable. Moreover, horizontal displacement or twisting is particularly disadvantageous in active vibration reduction systems because the relative parts of the non-contact actuators are relatively displaced or twisted. For example, in the case of a Lorentz coil, this may result in a too small gap or direct contact between the limit sleeve and the floating top plate, while the plunger coil contacts the permanent magnet, or at least the air gap between the plunger coil and the permanent magnet is no longer within the specified size.

[0004] Therefore, in the active vibration reduction system, after the coil spring floats, the system needs to be adjusted in the horizontal direction to solve the problem of abnormal operation of the non-contact actuator caused by horizontal displacement or torsion of the load. However, the existing solutions for adjusting the active vibration reduction system in the horizontal direction are difficult and complicated to adjust. Summary of the invention

[0029] The following is a detailed description with reference to specific embodiments. It should be noted that the serial numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

[0030] See also Figures 1 to 10 , Figure 1 is a schematic diagram of the three-dimensional structure of the shock absorber provided in the embodiment of the present application, Figure 2 is a schematic diagram of the main structure of the shock absorber provided in the embodiment of the present application, Figure 3 is a left-side structural schematic diagram of a shock absorber provided in an embodiment of the present application, Figure 4 is a schematic diagram of the right body structure of the shock absorber provided in an embodiment of the present application, Figure 5 is a rear view structural diagram of the shock absorber provided in an embodiment of the present application, Figure 6 is a schematic diagram of a top view of the structure of a shock absorber provided in an embodiment of the present application, Figure 7 is a bottom view of the structure of the shock absorber provided in the embodiment of the present application, Figure 8 is a three-dimensional structural diagram of a part of the structure of the shock absorber provided in an embodiment of the present application, Fig. 9 is a schematic diagram of the main structure of a part of the structure of the shock absorber provided in an embodiment of the present application, Fig.10 : is an exploded view of a part of the structure of the shock absorber provided in the embodiment of the present application. Figures 1 to 10As shown, the vibration damper 1 comprises a bottom plate 11 and a top plate 12 which are arranged relatively spaced apart along a first direction Z, a passive vibration damping assembly 13 and an adapter plate 14. The passive vibration damping assembly 13 is arranged between the bottom plate 11 and the top plate 12, and the two opposite ends of the passive vibration damping assembly 13 along the first direction Z are respectively connected to the bottom plate 11 and the top plate 12. The adapter plate 14 is located between the bottom plate 11 and the top plate 12, and is spaced apart from the passive vibration damping assembly 13 to avoid contact between the passive vibration damping assembly 13 and the adapter plate 14, thereby ensuring that the vibration damping effect of the passive vibration damping assembly 13 is not affected by the adapter plate 14.

[0031] In addition, the adapter plate 14 is arranged on the bottom plate 11 in an adjustable position, and a receiving space 15 is provided between the adapter plate 14 and the top plate 12, and the receiving space 15 is used to install other functional components, wherein the other functional components may refer to other functional devices in the shock absorber 1 except the passive vibration reduction component 13 (for example, the limit support component 19, the motor component 21 / 22 and the displacement sensor component 23, etc.). In this way, by introducing the adapter plate 14 between the bottom plate 11 and the top plate 12 in the shock absorber 1, other functional components except the passive vibration reduction component 13 can be installed on the adapter plate 14 in the accommodating space 15 between the adapter plate 14 and the top plate 12, instead of directly installing other functional components on the bottom plate 11. Further, during the debugging process of the shock absorber, if the passive vibration reduction component 13 is twisted, causing the top plate 12 to be horizontally offset or twisted relative to the bottom plate 11, by adjusting the position of the adapter plate 14 on the bottom plate 11, the translation adjustment of other functional components except the passive vibration reduction component 13 in the shock absorber 1 in the horizontal plane can be achieved, ensuring that the abnormal working problems of other functional components that may be caused by the horizontal offset of the top plate 12 are solved, the adjustment method is simple, and the adjustment efficiency is high, thereby reducing the debugging difficulty of the shock absorber 1 and reducing the debugging time of the shock absorber 1, which is beneficial to reducing the debugging cost of the shock absorber 1 and improving the debugging efficiency of the shock absorber 1.

[0032] It should be noted that the first direction Z in the embodiment of the present application may be a vertical direction, and the vertical direction in the embodiment of the present application may refer to any direction perpendicular to the horizontal plane, and the horizontal direction in the embodiment of the present application may refer to any direction parallel to the horizontal plane.

[0033] Specifically, Figures 8 to 10 As shown, the adapter plate 14 and the top plate 12 can be arranged relatively spaced along the first direction Z, and a through hole 141 can be opened on the adapter plate 14. The passive vibration reduction component 13 can pass through the through hole 141, and the part of the passive vibration reduction component 13 located in the through hole 141 is spaced from the inner side wall of the through hole 141 to avoid the passive vibration reduction component 13 from contacting the inner side wall of the through hole 141, thereby ensuring that the vibration reduction effect of the passive vibration reduction component 13 is not affected by the adapter plate 14.

[0034] Furthermore, in a specific implementation, the adapter plate 14 may include a middle area and an edge area surrounding the middle area, and the through hole 141 may be specifically provided in the middle area of ​​the adapter plate 14. The top plate 12 may include a middle area and an edge area surrounding the middle area, the bottom plate 11 may include a middle area and an edge area surrounding the middle area, and one end (i.e., the top end) of the passive vibration reduction component 13 may be connected to the middle area of ​​the top plate 12, and the other end (i.e., the bottom end) of the passive vibration reduction component 13 may pass through the through hole 141 and be connected to the middle area of ​​the bottom plate 11.

[0035] Specifically, the adapter plate 14 can have a first state and a second state. Furthermore, when the adapter plate 14 is in the first state, the adapter plate 14 is connected to the bottom plate 11, and the position of the adapter plate 14 on the bottom plate 11 cannot be adjusted; when the adapter plate 14 is in the second state, the adapter plate 14 is not connected to the bottom plate 11, and the position of the adapter plate 14 on the bottom plate 11 can be adjusted. In this way, the position of the adapter plate 14 on the bottom plate 11 can be adjusted only when the adapter plate 14 is in the second state, thereby avoiding misoperation.

[0036] In some embodiments, Figures 11 to 13 As shown, in the above shock absorber 1, at least one position adjustment hole 142 may be provided on the side of the adapter plate 14 facing the bottom plate 11 (i.e., the bottom side), and the above shock absorber 1 may also include at least one first connection structure 16, and the number of the first connection structures 16 may be equal to the number of the position adjustment holes 142, and the first connection structures 16 and the position adjustment holes 142 may correspond one to one. It is understandable that a suitable number of position adjustment holes 142 may be provided on the side of the adapter plate 14 facing the bottom plate 11 (i.e., the bottom side), and the design of the position adjustment holes 142 should ensure that the adapter plate 14 is firmly connected to the bottom plate 11 and is easy to operate.

[0037] Specifically, the first connecting structure 16 is connected to the base plate 11, and at least a portion of the first connecting structure 16 is accommodated in the corresponding position adjustment hole 142. There is a gap between the portion of the first connecting structure 16 located in the position adjustment hole 142 and the inner wall of the position adjustment hole 142, thereby realizing the horizontal movement of the adapter plate 14, and the maximum allowable distance of the horizontal movement of the adapter plate 14 is not greater than the maximum spacing of the gap.

[0038] Furthermore, in a specific implementation, when the adapter plate 14 is in the first state, the adapter plate 14 is connected to the bottom plate 11, and the gap between the inner side wall of the position adjustment hole 142 and the portion of the first connection structure 16 located in the position adjustment hole 142 may be non-adjustable; when the adapter plate 14 is in the second state, the adapter plate 14 is not connected to the bottom plate 11, and the gap between the inner side wall of the position adjustment hole 142 and the portion of the first connection structure 16 located in the position adjustment hole 142 may be adjustable. In this way, it is possible to adjust the gap between the inner side wall of the position adjustment hole 142 and the portion of the first connection structure 16 located in the position adjustment hole 142 by horizontally moving the adapter plate 14 only when the adapter plate 14 is in the second state, that is, only when the adapter plate 14 is not connected to the bottom plate 11, thereby avoiding misoperation.

[0039] Specifically, Figures 11 to 13 As shown, the position adjustment hole 142 can pass through the adapter plate 14, the first connecting structure 16 can have a first end and a second end (i.e., a bottom end and a top end) relative to each other, and the first end (i.e., the bottom end) of the first connecting structure 16 can be fixed to the base plate 11, and the second end (i.e., the top end) of the first connecting structure 16 can pass through the position adjustment hole 142 and protrude and be exposed on the side of the adapter plate 14 facing away from the base plate 11 (i.e., the top side).

[0040] In some specific embodiments, Fig.14 As shown, the first connection structure 16 may include a base 161 and a protrusion 162 , wherein the base 161 has a first surface and a second surface (ie, a lower surface and an upper surface) opposite to each other, and the protrusion 162 is disposed on the first surface (ie, the lower surface) of the base 161 . Furthermore, when the adapter plate 14 is in the first state, the first surface (i.e., the lower surface) of the base 161 of the first connecting structure 16 is arranged toward the adapter plate 14, and the base 161 of the first connecting structure 16 is fixed to the adapter plate 14, and the protrusion 162 of the first connecting structure 16 passes through the corresponding position adjustment hole 142 on the adapter plate 14 and is fixed to the bottom plate 11, so that the adapter plate 14 and the bottom plate 11 are connected together through the first connecting structure 16; when the adapter plate 14 is in the second state, the base 161 of the first connecting structure 16 is loosened from the adapter plate 14, so that the connection between the adapter plate 14 and the bottom plate 11 is disconnected, so that the gap between the inner side wall of the position adjustment hole 142 and the part of the protrusion 162 of the first connecting structure 16 located in the position adjustment hole 142 can be adjusted by horizontally moving the adapter plate 14, thereby realizing the translation adjustment of other functional devices installed on the adapter plate 14 in the horizontal plane.

[0041] Specifically, Figures 11 to 13As shown, a first positioning hole 111 may be provided in an area corresponding to the position adjustment hole 142 on one side of the bottom plate 11 facing the top plate 12, the first positioning hole 111 is connected to the position adjustment hole 142, and the first connection structure 16 is connected to the corresponding first positioning hole 111 on the bottom plate 11. Thus, by providing the first positioning hole 111, it is convenient to quickly install the first connection structure 16 and improve work efficiency.

[0042] For example, Fig.12 As shown, in the above shock absorber 1 , the number of the position adjustment holes 142 may be six, and the six position adjustment holes 142 may be specifically arranged in the edge area of ​​the adapter plate 14 .

[0043] For example, the cross-sectional shape of the position adjustment hole 142 may be circular (eg Fig.12 As shown, the cross-sectional shape of the first positioning hole 111 may be circular (as shown in Fig.13 as shown).

[0044] For example, Fig.12 As shown, the orthographic projection of the position adjustment hole 142 on the horizontal plane can completely cover the orthographic projection of the first positioning hole 111 on the horizontal plane, and the orthographic projection area of ​​the position adjustment hole 142 on the horizontal plane can be larger than the orthographic projection area of ​​the first positioning hole 111 on the horizontal plane.

[0045] Exemplarily, the orthographic projection on the horizontal plane of the gap between the inner side wall of the position adjustment hole 142 and the portion of the raised portion 162 of the first connecting structure 16 located in the position adjustment hole 142 can be completely covered by the orthographic projection of the base 161 of the first connecting structure 16 on the horizontal plane, and the orthographic projection area of ​​the base 161 of the first connecting structure 16 on the horizontal plane can be larger than the orthographic projection area of ​​the gap between the inner side wall of the position adjustment hole 142 and the portion of the raised portion 162 of the first connecting structure 16 located in the position adjustment hole 142, so as to ensure that the base 161 of the first connecting structure 16 can be firmly abutted against the side of the adapter plate 14 facing away from the bottom plate 11, without the need for additional connecting parts to fix the base 161 of the first connecting structure 16 to the adapter plate 14.

[0046] For example, Fig.14 As shown, the first connection structure 16 may be specifically a screw, and the base 161 and the protrusion 162 of the first connection structure 16 may be the nut and the screw rod of the screw respectively.

[0047] In addition, it should be noted that the embodiment of the present application does not limit the shape, number and distribution position of the position adjustment holes 142, the specific structure of the first connection structure 16, and the size relationship between the first connection structure 16 and the position adjustment holes 142. The position adjustment holes 142 and the first connection structure 16 can be used to horizontally adjust other functional components installed on the adapter plate 14 to the expected position by horizontally moving the adapter plate 14.

[0048] In some specific embodiments, the shock absorber 1 may have a working state and a non-working state. Figures 1 to 7 As shown, the shock absorber 1 may further include a second connecting structure 17, which is configured to connect the adapter plate 14 and the top plate 12 together when the shock absorber 1 is in a non-working state, thereby preventing the adapter plate 14 from moving relative to the top plate 12 in the non-working state and facilitating the transportation of the shock absorber 1 in the non-working state.

[0049] Specifically, Figures 1 to 7 As shown, the second connection structure 17 may include a first connection member 171 and a second connection member 172. Furthermore, when the shock absorber 1 is in a non-working state, the two opposite ends of the top plate 12 along the second direction X may be respectively connected to one end (i.e., the top end) of the first connection member 171 along the first direction Z and one end (i.e., the top end) of the second connection member 172 along the first direction Z, and the two opposite ends of the adapter plate 14 along the second direction X may be respectively connected to the other end (i.e., the bottom end) of the first connection member 171 along the first direction Z and the other end (i.e., the bottom end) of the second connection member 172 along the first direction Z, wherein the second direction X is perpendicular to the first direction Z.

[0050] For example, Figures 1 to 7 As shown, the first connecting member 171 and the second connecting member 172 may both be plate-shaped and may have the same shape and size. Figures 1 to 7 As shown, the first connecting member 171 and the second connecting member 172 may both be rectangular plates.

[0051] In some specific embodiments, Figures 11 to 13As shown, in the above shock absorber 1, a second positioning hole 143 may be provided on the side of the adapter plate 14 facing the bottom plate 11, and the second positioning hole 143 penetrates the adapter plate 14. A third positioning hole 112 may be provided on the side of the bottom plate 11 facing the top plate 12 in an area corresponding to the second positioning hole 143, and the third positioning hole 112 is connected to the second positioning hole 143. In addition, the above shock absorber 1 may further include a positioning structure 18, which is respectively matched with the second positioning hole 112 and the third positioning hole 143, and the positioning structure 18 is configured to pass through the second positioning hole 112 and insert into the third positioning hole 143 when the shock absorber 1 is in a non-working state, so as to realize the positioning of the adapter plate 14 at the initial position on the bottom plate 11, thereby facilitating the installation of the adapter plate 14.

[0052] Furthermore, in a specific implementation, when the shock absorber 1 is in working condition or during the debugging of the shock absorber 1 , the positioning structure 18 is disengaged from the second positioning hole 112 and the third positioning hole 143 to prevent the positioning structure 18 from preventing the adapter plate 14 from moving horizontally.

[0053] Exemplarily, the positioning structure 18 may be specifically a latch.

[0054] For example, in the shock absorber 1, the number of the positioning structures 18 may be multiple, the number of the second positioning holes 143 may be multiple, the number of the third positioning holes 112 may be multiple, and the multiple third positioning holes 112 may correspond to the multiple positioning structures 18 one by one, and the multiple third positioning holes 112 may correspond to the multiple positioning structures 18 one by one. Moreover, each positioning structure 18 may be specifically configured to be inserted into the corresponding third positioning hole 143 through the corresponding second positioning hole 112 when the shock absorber 1 is in a non-working state.

[0055] For example, Figures 11 to 13 As shown, in the above-mentioned shock absorber 1 , the number of the second positioning holes 143 can be specifically two, and the two second positioning holes 143 can be respectively arranged at the edge areas on the opposite sides of the adapter plate 14 .

[0056] For example, Figures 11 to 13 As shown, in the above shock absorber 1, the orthographic projection of the adapter plate 14 on the horizontal plane can be completely covered by the orthographic projection of the base plate 11 on the horizontal plane, and the orthographic projection area of ​​the adapter plate 14 on the horizontal plane can be smaller than the orthographic projection area of ​​the base plate 11 on the horizontal plane.

[0057] In the above embodiment, if Figures 8 to 10As shown, the passive vibration reduction assembly 13 may include a spring 131, an upper limit structure 132 and a lower limit structure 133. The lower limit structure 133 is connected to the bottom plate 11, the upper limit structure 132 is located on the side of the lower limit structure 133 away from the bottom plate 11, and is relatively spaced from the lower limit structure 133 along the first direction Z, and the upper limit structure 132 is connected to the top plate 12, the spring 131 is arranged between the upper limit structure 132 and the lower limit structure 133, and the length direction of the spring 131 is parallel to the first direction Z. Exemplarily, the spring 131 may be a steel spring.

[0058] Specifically, the height of the lower limit structure 133 relative to the base plate 11 can be adjustable, so that the distance between the upper limit structure 132 and the lower limit structure 133 can be adjusted by adjusting the height of the lower limit structure 133 relative to the base plate 11, thereby achieving the purpose of adjusting the deformation degree of the spring 131, so that the bearing capacity of the spring 131 in the static initial position is adjustable within a certain range, thereby achieving the ability of the shock absorber 1 to adapt to different load weights.

[0059] In some examples, such as Figures 8 to 10 As shown, in the above-mentioned passive vibration reduction component 13, the lower limit structure 133 may include a lower limit plate 1331 and a support rod 1332, wherein the length direction of the support rod 1332 is parallel to the first direction Z, and one end (i.e., the bottom end) of the support rod 1332 along its length direction is connected to the base plate 11, the lower limit plate 1331 is arranged on the support rod 1332, and the position of the lower limit plate 1331 on the support rod 1332 may be adjustable, so that the height of the lower limit plate 1331 relative to the base plate 11 can be adjusted by adjusting the position of the lower limit plate 1331 on the support rod 1332.

[0060] Specifically, Figures 8 to 10 As shown, the above-mentioned passive vibration reduction component 13 may also include a nut 134, which is located between the lower limit plate 1331 and the base plate 11 and can be connected to the support rod 1332 by threads, and the lower limit plate 1331 and the nut 134 can be abutted against each other, so that by rotating the nut 134, the lower limit plate 1331 can follow the nut 134 and move up and down along the length direction of the support rod 1332 synchronously to compress or release the spring 131, thereby realizing vertical height adjustment.

[0061] For example, Figures 8 to 10 As shown, the support rod 1332 can be a screw rod 1332, and the screw rod 1332 is adapted to the nut 1334. Specifically, the lower end of the screw rod 1332 can be connected to the corresponding threaded hole on the bottom plate 11 by threading, or can be clamped in the corresponding positioning hole on the bottom plate 11, so as to achieve a fixed connection between the screw rod 134 and the bottom plate 11.

[0062] In some examples, such as Figures 8 to 10 As shown, in the above-mentioned passive vibration reduction assembly 13, the upper limit structure 132 may include an upper limit plate 1321, and the upper limit plate 1321 is fixed on the side of the top plate 12 facing the bottom plate 11. Exemplarily, the upper limit plate 1321 can be connected to the side of the top plate 12 facing the bottom plate 11 by screws, and can be arranged parallel to the horizontal plane.

[0063] Furthermore, in a specific implementation, in the above-mentioned passive vibration reduction assembly 13, the upper limit plate 1321 of the upper limit structure 132 may have a first surface (i.e., an upper surface) that is away from the lower limit structure 133 (e.g., the lower limit plate 1331) and a second surface (i.e., a lower surface) that is toward the lower limit structure 133 (e.g., the lower limit plate 1331). Furthermore, the upper limit structure 132 may also include a first protrusion, which may be disposed on the middle area of ​​the second surface of the upper limit plate 1321, and one end (i.e., the top end) of the spring 131 along its length direction may be sleeved on the first protrusion and abut against the second surface of the upper limit plate 1321, thereby realizing the positioning of the upper end of the spring 131 by the upper limit structure 132.

[0064] In the above-mentioned passive vibration reduction assembly 13, the lower limit plate 1331 of the lower limit structure 133 may have a first surface (i.e., a lower surface) away from the upper limit structure 132 (e.g., the upper limit plate 1321) and a second surface (i.e., an upper surface) facing the upper limit structure 132 (e.g., the upper limit plate 1321). In addition, the lower limit structure 133 may also include a second protrusion 1333, which may be disposed on the middle area of ​​the second surface of the lower limit plate 1331, and the two opposite ends (i.e., the top and the bottom) of the spring 131 along its length direction may be respectively sleeved on the first protrusion of the upper limit structure 132 and the second protrusion 1333 of the lower limit structure 133, and respectively abut against the second surface of the upper limit plate 1321 and the second surface of the lower limit plate 1331, thereby realizing the positioning of the spring 131 between the upper limit structure 132 and the lower limit structure 133.

[0065] Specifically, Figures 8 to 10 As shown, a through hole may be provided in the middle area of ​​the second surface (i.e., the lower surface) of the lower limiting plate 1331 of the lower limiting structure 133, and the through hole passes through the lower limiting plate 1331 and the second protrusion 1333. In addition, one end (i.e., the bottom end) of the support rod 1332 along its length direction may be fixedly connected to the bottom plate 11, and the other end (i.e., the top end) may pass through the through hole and extend into the area between the lower limiting plate 1331 and the upper limiting plate 1321, and the bottom end of the spring 131 may be sleeved on the support rod 1332 extending into the area, so that the support rod 1332 passes through the lower limiting plate 1331 and the second protrusion 1333 and supports the spring 131.

[0066] In this way, after the load is installed on the top plate 12, the spring 131 can be compressed by lifting the lower limit plate 1331 (or the lower limit structure 133), and after lifting to a suitable height, the gravity of the load and the top plate 12 can be balanced by the compression reaction force of the spring 131, and then the height of the lower limit plate 1331 relative to the bottom plate 11 can be further fine-tuned to make the load and the top plate 12 reach the designed working height. After that, the vertical vibration and horizontal vibration of the bottom plate 11 can be transmitted to the load and the top plate through the support rod 1332, the lower limit plate 1331, the spring 131, and the upper limit plate 1311. At this time, the spring 131 plays a role in vertical vibration isolation and horizontal vibration isolation.

[0067] In some embodiments, after the load is installed on the top plate 12, the spring 131 is compressed by lifting the lower limit plate 1331 (or the lower limit structure 133), so that the torsion of the spring 131 is reduced during the process of the load and the top plate 12 reaching the designed working height, thereby reducing the horizontal deviation of the load and the top plate 12, such as Figures 8 to 10 As shown, a first latch hole 13311 may be provided on the edge area of ​​the lower stop plate 1331 of the lower stop structure 133. The above-mentioned passive vibration reduction component 13 may also include a first latch 135, and the number of the first latch 135 may be equal to the number of the first latch holes 13311, for example, there may be two first latches 135. The first latches 135 and the first latch holes 13311 may correspond one to one, and each first latch 135 may be adapted to its corresponding first latch hole 13311. Furthermore, when the shock absorber 1 is in a non-working state, the first latch 135 can pass through the corresponding first latch hole 13311 from the side of the lower limit plate 1331 away from the bottom plate 11 and be fixed to the bottom plate 11 and / or the adapter plate 14, thereby reducing the torsion of the spring 131 during the process of adjusting the initial deformation degree of the spring 131; when the shock absorber 1 is in a working state, the first latch 135 can be disengaged from the corresponding first latch hole 13311 and the bottom plate 11 and the adapter plate 14, thereby ensuring that the vibration reduction effect of the passive vibration reduction assembly 13 is not affected by the first latch 135.

[0068] Furthermore, it should be noted that the embodiment of the present application does not limit the specific structure of the passive vibration reduction component 13 , and the passive vibration reduction component 13 can provide vertical passive vibration isolation and horizontal passive vibration isolation in the vibration absorber 1 .

[0069] In the above embodiment, if Figure 8 , Fig. 9 , Fig.10 , Fig.15 and Fig.16As shown, other functional components of the shock absorber 1 except the passive vibration reduction component 13 may include a limit support component 19, which is arranged in the accommodating space 15 and may include a limit support seat 191 and a limit structure 192. The limit support seat 191 is connected to the adapter plate 14, and a limit groove 121 is provided on the side of the top plate 12 facing the bottom plate 11 in an area corresponding to the limit support seat 191, and the limit structure 192 is connected to the limit support seat 191, and at least part of the limit structure 192 is accommodated in the limit groove 121, and there is a gap between the outer side wall of the limit structure 192 and the inner side wall of the limit groove 121.

[0070] Specifically, the limiting structure 192 may have a first end and a second end (i.e., a bottom end and a top end) relative to each other, and the first end (i.e., the bottom end) of the limiting structure 192 may be fixed to the limiting support seat 191, and the second end (i.e., the top end) of the limiting structure 192 may pass through the limiting groove 121 and protrude and be exposed on the side of the top plate 12 facing away from the limiting support seat 191 (i.e., the top side).

[0071] In addition, the limiting support assembly 19 may further include a stopper 194, which may be fixed to a portion of the limiting structure 192 that protrudes and is exposed on the top side of the top plate 12 (eg, Fig.16 ), and the stopper 194 can be configured to prevent the limiting structure 192 from being separated from the limiting groove 121. In this way, in the vertical direction, if the limiting structure 192 is excessively lifted, the top plate 12 will first hit the stopper 194 to prevent the limiting structure 192 from being separated from the limiting groove 121 upward, thereby avoiding the problem of the top plate 12 being unstable due to excessive vertical movement, so as to achieve the purpose of protecting the vibration-damped equipment on the top plate 12.

[0072] For example, Fig.16 As shown, in the limiting support assembly 19 , the stopper 194 and the limiting structure 192 may be an integrally formed structure, and the stopper 194 may be protrudingly disposed around the outer side wall of the top end of the limiting structure 192 .

[0073] Exemplarily, the orthographic projection of the gap between the outer wall of the limiting structure 192 and the inner wall of the limiting groove 121 on the horizontal plane can be completely covered by the orthographic projection of the stop member 194 on the horizontal plane, and the orthographic projection area of ​​the stop member 194 on the horizontal plane can be larger than the orthographic projection area of ​​the gap between the outer wall of the limiting structure 192 and the inner wall of the limiting groove 121 on the horizontal plane, so as to ensure that the stop member 194 can effectively prevent the limiting structure 192 from detaching from the limiting groove 121.

[0074] In some specific embodiments, Fig.17As shown, a limiting structure accommodating groove 1911 can be opened on the side of the limiting support seat 191 facing the top plate 12 (i.e., the top side) in the area corresponding to the limiting structure 192, and the first end (i.e., the bottom end) of the limiting structure 192 can extend into the limiting structure accommodating groove 1911 and can be fixed in the limiting structure accommodating groove 1911, thereby fixing the limiting structure 192 on the top side of the limiting structure 192.

[0075] Specifically, a first through hole may be provided on the middle area of ​​the surface of the limiting structure 192 that is away from the bottom plate 11 (ie, the top surface), and the first through hole penetrates the limiting structure 192. Fig.16 As shown, the limiting support assembly 19 may further include a locking screw 195 , which may pass through the first through hole and be connected to the limiting support seat 191 , so that the bottom end of the limiting structure 192 is fixed in the limiting structure receiving groove 1911 through the locking screw 195 .

[0076] For example, Fig.17 As shown, a first groove may be opened on the bottom wall surface of the limiting structure accommodating groove 1911, and the locking screw 195 may be fixedly connected to the first groove by a thread after passing through the first through hole.

[0077] In some specific embodiments, the above-mentioned limit support assembly 19 can have a working state and a non-working state. Figures 8 to 10 As shown, the limit support assembly 19 may further include a transport locking screw 193, and the transport locking screw 193 may be configured to fix the limit support seat 191 to the top plate 12 when the limit support assembly 19 is in a non-working state, thereby preventing the limit support seat 191 from moving relative to the top plate 12 in the non-working state, so as to facilitate the transportation of the shock absorber 1 in the non-working state.

[0078] Furthermore, when the position limiting support assembly 19 is in working condition, the transport locking screw 193 can be separated from the position limiting support seat 191 and / or the top plate 12 , thereby ensuring that the position limiting support seat 191 can play a position limiting role on the top plate 12 .

[0079] Specifically, Fig.17 As shown, the end (i.e., the top end) of the position-limiting support seat 191 facing the top plate 12 may be provided with a connecting plate 1912 protruding in the lateral direction, wherein the lateral direction may be any direction parallel to the horizontal plane. In addition, a second through hole may be provided on the surface (i.e., the bottom surface) of the connecting plate 1912 facing the bottom plate 11, and the second through hole passes through the connecting plate 1912. In addition, when the position-limiting support assembly 19 is in a non-working state, the transport locking screw 193 may pass through the second through hole and be connected to the top plate 12, so that the top end of the position-limiting support seat 191 is fixed to the bottom side of the top plate 12 through the transport locking screw 193.

[0080] Furthermore, in a specific implementation, a groove may be provided on a side (i.e., the bottom side) of the top plate 12 facing the bottom plate 11 in an area corresponding to the transport locking screw 193, and the transport locking screw 193 may be fixedly connected to the groove by a thread after passing through the second through hole.

[0081] For example, Figures 8 to 10 As shown, the shock absorber 1 may include at least one first position-limiting support assembly 19A and / or at least one second position-limiting support assembly 19B. For example, it may specifically include two first position-limiting support assemblies 19A and one second position-limiting support assembly 19B. Moreover, the specific structure of the first position-limiting support assembly 19A can refer to the description of the position-limiting support assembly 19 in the above embodiment, so it will not be repeated here. The specific structure of the second position-limiting support assembly 19B may be substantially the same as the specific structure of the first position-limiting support assembly 19A, and the difference between the two may only be that the second position-limiting support assembly 19B does not include the transport locking screw 193, and the resulting difference between the position-limiting support seat 192 included in the two.

[0082] Furthermore, it should be noted that the embodiment of the present application does not limit the specific structure, quantity and distribution position of the position-limiting support assembly 19 , and the position-limiting support assembly 19 can only limit the top plate 12 in the shock absorber 1 .

[0083] In the above embodiment, if Figures 1 to 7 As shown, other functional components of the shock absorber 1 except the passive vibration reduction component 13 may include a first motor component 21 and / or a second motor component 22 .

[0084] Specifically, the first motor assembly 21 is disposed in the accommodating space 15, and may include a first stator 211 and a first mover 212. One of the first stator 211 and the first mover 212 is connected to the adapter plate 14, and the other is connected to the top plate 12. In addition, the first mover 212 may be configured to move horizontally upward relative to the first stator 211 to achieve the horizontal active vibration reduction function of the above-mentioned shock absorber 1.

[0085] For example, Figures 1 to 7 As shown, the first stator 211 included in the above-mentioned first motor assembly 21 can be connected to the adapter plate 14, for example, it can be connected to the adapter plate 14 through a first adapter 213, and the first mover 212 included in the above-mentioned first motor assembly 21 can be connected to the top plate 12, for example, it can be connected to the top plate 12 through screws, so that the above-mentioned first motor assembly 21 is installed in the accommodating space 15 between the adapter plate 14 and the top plate 12.

[0086] Specifically, Figures 1 to 7 and Fig.18 As shown, the second motor assembly 22 is disposed in the accommodating space 15 and may include a second stator 221 and a second mover 222. One of the second stator 221 and the second mover 222 is connected to the adapter plate 14, and the other is connected to the top plate 12. In addition, the second mover 222 may be configured to move vertically relative to the second stator 221 to achieve the vertical active vibration reduction function of the above-mentioned shock absorber 1.

[0087] For example, Figures 1 to 7 and Fig.18 As shown, the second stator 221 included in the above-mentioned second motor assembly 22 can be connected to the adapter plate 14, for example, it can be connected to the adapter plate 14 through a second adapter 223, and the second mover 222 included in the above-mentioned second motor assembly 22 can be connected to the top plate 12, for example, it can be connected to the top plate 12 through screws, so as to realize that the above-mentioned second motor assembly 22 is installed in the accommodating space 15 between the adapter plate 14 and the top plate 12.

[0088] In some specific embodiments, the shock absorber 1 may include one or more first motor components 21. Specifically, Figures 1 to 7 As shown, the shock absorber 1 may specifically include two first motor assemblies 21 , and the two first motor assemblies 21 may each have an independent first adapter 213 for connecting the stator included therein (ie, the first stator 211 ) to the adapter plate 14 .

[0089] In some specific embodiments, the shock absorber 1 may include one or more second motor assemblies 22. Specifically, Figures 1 to 7 and Fig.18 As shown, the shock absorber 1 may specifically include four second motor assemblies 22, which may be divided into two groups, each group of second motor assemblies 22 may include two second motor assemblies 22, and all second motor assemblies 22 in the same group may share the same second adapter 223, and second motor assemblies 22 in different groups may have different second adapters 223. In other words, the stators (i.e., second stators 221) included in all second motor assemblies 22 in the same group may be connected to the adapter plate 14 through the same second adapter 223, and the stators included in second motor assemblies 22 in different groups may be connected to the adapter plate 14 through different second adapters 223. In this way, it is beneficial to improve the space utilization rate in the shock absorber 1.

[0090] In the above embodiment, if Fig.18As shown, other functional components of the above-mentioned shock absorber 1 except the passive vibration reduction component 13 may include a displacement sensor component 23, which is arranged in the accommodating space 15 and can be used to detect the movement displacement of the top plate 12. Specifically, the displacement sensor component 23 may include a mounting bracket 231 and a displacement sensor 232. The mounting bracket 231 is connected to the adapter plate 14, and the displacement sensor 232 is installed on the mounting bracket 231.

[0091] Specifically, in the above-mentioned embodiment in which the shock absorber 1 includes a limit support assembly 19, the mounting bracket 231 of the displacement sensor assembly 23 can be connected to the limit support seat 191 of the limit support assembly 19, for example, it can be connected to the limit support seat 191 of the limit support assembly 19 by screws, thereby realizing the connection between the mounting bracket 231 of the displacement sensor assembly 23 and the adapter plate 14.

[0092] In some specific embodiments, the number of displacement sensors 232 included in the above-mentioned displacement sensor assembly 23 can be one or more, and each displacement sensor 232 can correspond to a preset direction, and can be specifically configured to detect the movement displacement of the top plate 12 in its corresponding preset direction, wherein the preset direction can be vertical or horizontal.

[0093] Specifically, the number of displacement sensors 232 included in the displacement sensor assembly 23 can be specifically two, which are recorded as: a first displacement sensor and a second displacement sensor. The first displacement sensor can be configured to detect the horizontal movement displacement of the top plate 12, and the second displacement sensor can be configured to detect the vertical movement displacement of the top plate 12. In other words, the first displacement sensor can be specifically a horizontal displacement sensor, and the second displacement sensor can be specifically a vertical displacement sensor.

[0094] In some examples, the displacement sensor assembly 23 further includes a shielding cylinder, and the shielding cylinders and displacement sensors 232 included in the displacement sensor assembly 23 may be equal in number and correspond one to one. Specifically, in the displacement sensor assembly 23, each shielding cylinder at least partially surrounds the corresponding displacement sensor 232 to shield the corresponding displacement sensor 232 from electromagnetic interference.

[0095] In some examples, the displacement sensor assembly 23 may further include a sensing sheet, and the sensing sheets and displacement sensors 232 included in the displacement sensor assembly may be equal in number and correspond one to one. Specifically, in the displacement sensor assembly 23, each sensing sheet is fixed on the side of the top plate 12 facing the bottom plate 11 (i.e., the bottom side), and is relatively spaced apart from the corresponding displacement sensor 232 along the corresponding preset direction.

[0096] In some specific embodiments, Fig.18 As shown, the shock absorber 1 may include both the first motor assembly 21 and / or the second motor assembly 22, and the displacement sensor assembly 23. In addition, the shock absorber 1 may further include a controller assembly 24, which is disposed in the accommodating space 15 and may include a controller 241 and a controller mounting bracket 242, wherein the controller mounting bracket 242 is connected to the adapter plate 14, and the controller 241 is mounted on the controller mounting bracket 242.

[0097] Specifically, the controller 241 may be configured to control the operation of the first motor assembly 21 and / or the second motor assembly 22 according to the detection result of the displacement sensor 232. In this way, by controlling the output of the first motor assembly 21 and / or the second motor assembly 22 in the shock absorber 1, the vibration state of the top plate 12 may be changed, thereby achieving the vibration reduction effect of the shock absorber 10.

[0098] For example, Figures 1 to 7 As shown, the shock absorber 1 may further include a protective side plate 25 , which is disposed around the outer wall of the accommodating space 15 between the top plate 12 and the adapter plate 14 to protect other functional components (eg, the controller 141 ) in the accommodating space 15 .

[0099] Specifically, the protective side panel 25 can be connected to the adapter plate 14 and other functional components in the accommodating space 15 , for example, can be connected to the adapter plate 14 and other functional components in the accommodating space 15 by screws, so as to ensure that the protective side panel 25 is firmly installed.

[0100] For example, Fig.18 As shown, the shock absorber 1 may further include a speed sensor 26 . The speed sensor 26 may be connected to the top plate 12 and may be used to detect the movement speed of the top plate 12 .

[0101] Specifically, Fig.18 As shown, the number of speed sensors 26 included in the displacement sensor assembly 1 can be specifically two, which are recorded as: a first speed sensor 26A and a second speed sensor 26B. The first speed sensor 26A can be configured to detect the horizontal movement speed of the top plate 12, and the second speed sensor 26B can be configured to detect the vertical movement speed of the top plate 12. In addition, the controller 241 can be specifically configured to control the operation of the first motor assembly 17 and / or the second motor assembly 18 according to the detection results of the displacement sensor 232 and / or the speed sensor 26.

[0102] In the above embodiment, the vibration damper 10 can be used as a vibration damping platform for damping the vibration of precision equipment such as semiconductor equipment and / or precision machine tools.

[0103] As can be seen from the above, the vibration damper provided in this embodiment comprises a bottom plate and a top plate which are arranged relatively spaced apart along a first direction, a passive vibration damping component and an adapter plate, wherein the passive vibration damping component is arranged between the bottom plate and the top plate, and the two opposite ends of the passive vibration damping component along the first direction are respectively connected to the bottom plate and the top plate, the adapter plate is located between the bottom plate and the top plate, and is spaced apart from the passive vibration damping component, and the adapter plate is arranged on the bottom plate in a positionally adjustable manner, and a receiving space is provided between the adapter plate and the top plate, and the receiving space is used to receive other functional components, so that other components except the passive vibration damping component can be received in the receiving space between the adapter plate and the top plate. Other functional components are installed on the adapter plate instead of directly on the bottom plate. Therefore, during the debugging process of the shock absorber, if the passive vibration reduction component is twisted, causing the top plate to be horizontally offset or twisted relative to the bottom plate, the translation adjustment of other functional components in the horizontal plane can be achieved by adjusting the position of the adapter plate on the bottom plate, ensuring that the abnormal working problems of other functional components that may be caused by the horizontal offset of the top plate are solved. The adjustment method is simple and efficient, thereby reducing the debugging difficulty and debugging time of the shock absorber, which is beneficial to reducing the debugging cost of the shock absorber and improving the debugging efficiency of the shock absorber.

[0104] An embodiment of the present application also provides a vibration reduction system, which includes the vibration reduction system of any of the above embodiments. Specifically, in the vibration reduction system, the vibration reduction system includes a bottom plate and a top plate arranged relatively spaced apart along a first direction, and a passive vibration reduction component and an adapter plate arranged between the bottom plate and the top plate. Among them, one end of the passive vibration reduction component along the first direction is connected to the bottom plate, and the other end of the passive vibration reduction component along the first direction is connected to the top plate. The adapter plate is spaced apart from the passive vibration reduction component, and the adapter plate is arranged on the bottom plate in a positionally adjustable manner, and a receiving space is provided between the adapter plate and the top plate, and the receiving space is used to install other functional components.

[0105] Specifically, the vibration reduction system may further include a load, and the load may be fixed above the top plate of the vibration reducer, thereby achieving vibration reduction of the load.

[0106] Illustratively, the load may be a semiconductor device, a precision machine tool, or other precision equipment.

[0107] In some embodiments, the vibration reduction system may include multiple shock absorbers (for example, at least three), and the vibration reduction system may further include a workbench installed above the multiple shock absorbers, so that the height of the workbench at the location of each shock absorber can be detected by a sensor, and based on the detection result of the sensor, the output of the motor in the shock absorber can be controlled to ensure that the workbench is always in a horizontal state.

[0108] It should be noted that the vibration reduction system provided in the embodiment of the present application, since the vibration reduction device provided in the embodiment of the present application is provided, can achieve the beneficial effects that can be achieved by any vibration reduction device provided in the embodiment of the present application. Please refer to the previous embodiment for details, which will not be repeated here.

[0109] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
