Shock absorber and shock absorption system

Abstract

The present application relates to a shock absorber and a shock absorption system. The shock absorber includes a bottom plate and a top plate that are relatively spaced apart, and a passive shock absorption component and a transfer plate disposed between the bottom plate and the top plate. The opposite ends of the passive shock absorption component are respectively connected to the bottom plate and the top plate. The transfer plate is spaced apart from the passive shock absorption component, and the transfer plate is disposed on the bottom plate in a position-adjustable manner, and a receiving space is provided between the transfer plate and the top plate. The receiving space is used to accommodate other functional components, so that other functional components can be installed on the transfer plate instead of directly on the bottom plate. Furthermore, during the debugging process of the shock absorber, if the passive shock absorption component twists, causing the top plate to undergo horizontal torsion or displacement relative to the bottom plate, by adjusting the position of the transfer plate on the bottom plate, the translation adjustment of other functional components in the horizontal plane can be realized, ensuring that the problems of abnormal operation of other functional components that may be caused by the horizontal displacement of the top plate are solved. The adjustment method is simple and efficient, thus improving the debugging efficiency.

Description

Technical Field

[0001] This application relates to the field of precision vibration damping technology, and particularly to a shock absorber and a vibration damping system. Background Art

[0002] Vibration damping systems including helical springs are well known, and the helical springs mainly adopt the form of steel springs. In such a system, the load to be isolated from the ground is mounted on three or more shock absorbers, which include helical springs effective at least in the vertical direction. In addition, the vibration damping effect of the vibration damping system can be improved by configuring it as an active vibration damping system. In the active vibration damping system, sensors are arranged on the load to be vibration-damped and / or on the ground, and at least one actuator is controlled through a control loop, and the actuator actively cancels vibrations. In particular, a non-contact actuator is used as the actuator, especially an actuator based on the Lorentz principle.

[0003] However, in the active vibration damping system, torque is generated during the floating process of the helical spring, which in turn causes a horizontal force. This horizontal force usually causes the load to shift or twist horizontally, which is an undesirable phenomenon. Moreover, in the active vibration damping system, horizontal shift or twist is particularly disadvantageous because the relative components of the non-contact actuator will thus undergo relative shift or twist. For example, in the case of a Lorentz coil, this may result in too small a gap or direct contact between the limit sleeve and the floating top plate, while the plunger coil contacts the permanent magnet, or at least causes the air gap size between the plunger coil and the permanent magnet to no longer meet the specified requirements.

[0004] Therefore, in the active vibration damping system, after the helical spring floats, it is necessary to adjust the system horizontally to solve the problem of abnormal operation of the non-contact actuator that may be caused by the horizontal shift or twist of the load. However, the existing solutions for horizontally adjusting the active vibration damping system have the problems of difficult and complex adjustment. Summary of the Invention

[0005] The purpose of this application is to provide a shock absorber and a vibration damping system to solve the problem of abnormal operation that may be caused by the common horizontal shift or twist of the helical spring vibration damping system, simplify the horizontal adjustment process of the active vibration damping system, reduce the adjustment difficulty, and thus significantly improve the debugging efficiency of the shock absorber.

[0048] A detailed description will be given below in conjunction with 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.

[0049] Please refer to Figures 1 to 10 , Figure 1 which is a schematic perspective view of a shock absorber provided by an embodiment of the present application, Figure 2 which is a schematic front view of a shock absorber provided by an embodiment of the present application, Figure 3 which is a schematic left view of a shock absorber provided by an embodiment of the present application, Figure 4 which is a schematic right body view of a shock absorber provided by an embodiment of the present application, Figure 5 which is a schematic rear view of a shock absorber provided by an embodiment of the present application, Figure 6 which is a schematic top view of a shock absorber provided by an embodiment of the present application, Figure 7 which is a schematic bottom view of a shock absorber provided by an embodiment of the present application, Figure 8 which is a schematic perspective view of a partial structure of a shock absorber provided by an embodiment of the present application, Figure 9 which is a schematic front view of a partial structure of a shock absorber provided by an embodiment of the present application, Figure 10 which is an exploded view of a partial structure of a shock absorber provided by an embodiment of the present application. As Figures 1 to 10As shown, the shock absorber 1 includes a bottom plate 11 and a top plate 12 that are relatively spaced apart along a first direction Z, a passive shock absorption assembly 13, and an adapter plate 14. Among them, the passive shock absorption assembly 13 is disposed between the bottom plate 11 and the top plate 12, and the two opposite ends of the passive shock absorption 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 shock absorption assembly 13 to prevent contact between the passive shock absorption assembly 13 and the adapter plate 14, thereby ensuring that the shock absorption effect of the passive shock absorption assembly 13 is not affected by the adapter plate 14.

[0050] Moreover, the adapter plate 14 is disposed on the bottom plate 11 in a position-adjustable manner, and there is an accommodation space 15 between the adapter plate 14 and the top plate 12. The accommodation space 15 is used to install other functional components. Among them, the other functional components can refer to other functional devices in the shock absorber 1 except the passive shock absorption assembly 13 (for example, a limit support assembly 19, a motor assembly 21 / 22, a displacement sensor assembly 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 shock absorption assembly 13 can be installed on the adapter plate 14 in the accommodation space 15 between the adapter plate 14 and the top plate 12, rather than directly installing other functional components on the bottom plate 11. Furthermore, during the debugging process of the shock absorber, if the passive shock absorption assembly 13 twists, causing the top plate 12 to horizontally shift or twist 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 in the shock absorber 1 except the passive shock absorption assembly 13 in the horizontal plane can be realized, ensuring that problems such as abnormal operation of other functional components that may be caused by the horizontal shift of the top plate 12 are solved. The adjustment method is simple and the adjustment efficiency is high, thus 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.

[0051] It should be noted that the first direction Z in the embodiments of the present application can be the vertical direction, and the vertical direction in the embodiments of the present application can refer to any direction perpendicular to the horizontal plane, and the horizontal direction in the embodiments of the present application can refer to any direction parallel to the horizontal plane.

[0052] Specifically, as Figures 8 to 10 shown, the adapter plate 14 and the top plate 12 can be relatively spaced apart along the first direction Z, and through holes 141 can be formed in the adapter plate 14. The passive shock absorption assembly 13 can pass through the through holes 141, and the part of the passive shock absorption assembly 13 located in the through holes 141 is spaced apart from the inner side wall of the through holes 141 to prevent contact between the passive shock absorption assembly 13 and the inner side wall of the through holes 141, thereby ensuring that the shock absorption effect of the passive shock absorption assembly 13 is not affected by the adapter plate 14.

[0053] Moreover, during specific implementation, the adapter plate 14 may include a middle region and an edge region surrounding the middle region, and the through hole 141 may be specifically provided in the middle region of the adapter plate 14. The top plate 12 may include a middle region and an edge region surrounding the middle region, the bottom plate 11 may include a middle region and an edge region surrounding the middle region, and one end (i.e., the top end) of the passive vibration damping assembly 13 may be connected to the middle region of the top plate 12, and the other end (i.e., the bottom end) of the passive vibration damping assembly 13 may pass through the through hole 141 and be connected to the middle region of the bottom plate 11.

[0054] Specifically, the above-mentioned adapter plate 14 may have a first state and a second state. Moreover, when the adapter plate 14 is in the first state, the adapter plate 14 is connected to the bottom plate 11, and at this time, the position of the adapter plate 14 on the bottom plate 11 is not adjustable; when the adapter plate 14 is in the second state, the adapter plate 14 is not connected to the bottom plate 11, and at this time, the position of the adapter plate 14 on the bottom plate 11 is adjustable. In this way, it can be realized that 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, thus avoiding misoperation.

[0055] In some embodiments, as Figures 11 to 13 shown, in the above-mentioned shock absorber 1, at least one position adjustment hole 142 may be formed on the side of the adapter plate 14 facing the bottom plate 11 (i.e., the bottom side). The shock absorber 1 may further include at least one first connection structure 16. Moreover, 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 to each other one by one. It can be understood that an appropriate number of position adjustment holes 142 may be formed 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 not only ensure the firm connection between the adapter plate 14 and the bottom plate 11 but also facilitate operation.

[0056] Specifically, the first connection structure 16 is connected to the bottom plate 11, and at least a part of the first connection structure 16 is received in the corresponding position adjustment hole 142. There is a gap between the part of the first connection structure 16 located in the position adjustment hole 142 and the inner side wall of the position adjustment hole 142, so that the adapter plate 14 can be horizontally moved, and the maximum allowable distance for the horizontal movement of the adapter plate 14 is not greater than the maximum distance of the gap.

[0057] Moreover, in 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 wall of the position adjustment hole 142 and the part of the first connection structure 16 located within 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 wall of the position adjustment hole 142 and the part of the first connection structure 16 located within the position adjustment hole 142 may be adjustable. In this way, it can be achieved that 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, can the gap between the inner wall of the position adjustment hole 142 and the part of the first connection structure 16 located within the position adjustment hole 142 be adjusted by horizontally moving the adapter plate 14, thus avoiding misoperation.

[0058] Specifically, as Figures 11 to 13 shown, the position adjustment hole 142 may penetrate the adapter plate 14, the first connection structure 16 may have opposite first and second ends (i.e., bottom end and top end), and the first end (i.e., bottom end) of the first connection structure 16 may be fixed to the bottom plate 11, and the second end (i.e., top end) of the first connection structure 16 may pass through the position adjustment hole 142 and protrude and be exposed on the side of the adapter plate 14 facing away from the bottom plate 11 (i.e., the top side).

[0059] In some specific embodiments, as Figure 14 shown, the above-mentioned first connection structure 16 may include a base 161 and a protrusion 162. Among them, the base 161 has opposite first and second surfaces (i.e., lower surface and upper surface), and the protrusion 162 is provided on the first surface (i.e., lower surface) of the base 161. And when the adapter plate 14 is in the first state, the first surface (i.e., lower surface) of the base 161 of the first connection structure 16 faces the adapter plate 14 and is fixed to the adapter plate 14, and the protrusion 162 of the first connection structure 16 passes through the corresponding position adjustment hole 142 on the adapter plate 14 and is fixed to the bottom plate 11 to realize the connection of the adapter plate 14 and the bottom plate 11 through the first connection structure 16; when the adapter plate 14 is in the second state, the base 161 of the first connection structure 16 is loosened from the adapter plate 14 to realize the disconnection of the connection between the adapter plate 14 and the bottom plate 11, so that the gap between the inner wall of the position adjustment hole 142 and the part of the protrusion 162 of the first connection structure 16 located within the position adjustment hole 142 can be adjusted by horizontally moving the adapter plate 14, and further realize the horizontal translation adjustment of other functional devices installed on the adapter plate 14.

[0060] Specifically, as Figures 11 to 13As shown, a first positioning hole 111 may be formed in the region of the bottom plate 11 facing the top plate 12 corresponding to the position adjustment hole 142. The first positioning hole 111 communicates with 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 beneficial to the rapid installation of the first connection structure 16 and improves work efficiency.

[0061] Exemplarily, as Figure 12 shown, in the above-mentioned shock absorber 1, the number of the position adjustment holes 142 may be six, and the six position adjustment holes 142 may be specifically provided in the edge region of the adapter plate 14.

[0062] Exemplarily, the cross-sectional shape of the position adjustment hole 142 may be circular (as Figure 12 shown), and the cross-sectional shape of the first positioning hole 111 may be circular (as Figure 13 shown).

[0063] Exemplarily, as Figure 12 shown, the orthographic projection of the position adjustment hole 142 on the horizontal plane may completely cover the orthographic projection of the first positioning hole 111 on the horizontal plane, and the area of the orthographic projection of the position adjustment hole 142 on the horizontal plane may be larger than the area of the orthographic projection of the first positioning hole 111 on the horizontal plane.

[0064] Exemplarily, the orthographic projection of the gap between the inner side wall of the position adjustment hole 142 and the part of the protruding portion 162 of the first connection structure 16 located within the position adjustment hole 142 on the horizontal plane may be completely covered by the orthographic projection of the base 161 of the first connection structure 16 on the horizontal plane, and the area of the orthographic projection of the base 161 of the first connection structure 16 on the horizontal plane may be larger than the area of the orthographic projection of the gap between the inner side wall of the position adjustment hole 142 and the part of the protruding portion 162 of the first connection structure 16 located within the position adjustment hole 142 on the horizontal plane, so as to ensure that the base 161 of the first connection structure 16 can firmly abut against the side of the adapter plate 14 facing away from the bottom plate 11 without the need for additional connecting members to fixedly connect the base 161 of the first connection structure 16 to the adapter plate 14.

[0065] Exemplarily, as Figure 14 shown, the above-mentioned first connection structure 16 may specifically be a screw, and the base 161 and the protruding portion 162 of the above-mentioned first connection structure 16 may be the nut and the screw rod of the screw respectively.

[0066] Moreover, it should be noted that the embodiments of the present application do 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 dimensional 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 achieve horizontal adjustment of other functional devices installed on the adapter plate 14 to the expected position by horizontally moving the adapter plate 14.

[0067] In some specific embodiments, the above-mentioned shock absorber 1 can have a working state and a non-working state. And, as Figures 1 to 7 shown, the above-mentioned shock absorber 1 can further include a second connection structure 17, which is configured to connect the adapter plate 14 and the top plate 12 together when the shock absorber 1 is in the non-working state, so as to prevent the adapter plate 14 from moving relative to the top plate 12 in the non-working state and facilitate the transportation of the shock absorber 1 in the non-working state.

[0068] Specifically, as Figures 1 to 7 shown, the above-mentioned second connection structure 17 can include a first connecting member 171 and a second connecting member 172. And when the shock absorber 1 is in the non-working state, the two opposite side ends of the top plate 12 along the second direction X can be respectively connected to one end (i.e., the top end) of the first connecting member 171 along the first direction Z and one end (i.e., the top end) of the second connecting member 172 along the first direction Z, and the two opposite side ends of the adapter plate 14 along the second direction X can be respectively connected to the other end (i.e., the bottom end) of the first connecting member 171 along the first direction Z and the other end (i.e., the bottom end) of the second connecting member 172 along the first direction Z, wherein the second direction X is perpendicular to the first direction Z.

[0069] Exemplarily, as Figures 1 to 7 shown, the first connecting member 171 and the second connecting member 172 can both be plate-shaped and can have the same shape and size. For example, as Figures 1 to 7 shown, the first connecting member 171 and the second connecting member 172 can both be rectangular plates.

[0070] In some specific embodiments, as Figures 11 to 13As shown, in the above shock absorber 1, a second positioning hole 143 may be formed on the side of the adapter plate 14 facing the bottom plate 11. The second positioning hole 143 penetrates through the adapter plate 14. A third positioning hole 112 may be formed in the area of the bottom plate 11 facing the top plate 12 corresponding to the second positioning hole 143. The third positioning hole 112 communicates with the second positioning hole 143. Moreover, the above shock absorber 1 may further include a positioning structure 18. The positioning structure 18 is adapted to the second positioning hole 112 and the third positioning hole 143 respectively, and the positioning structure 18 is configured to insert into the third positioning hole 143 through the second positioning hole 112 when the shock absorber 1 is in a non-operating state, so as to position the initial position of the adapter plate 14 on the bottom plate 11, thus facilitating the installation of the adapter plate 14.

[0071] Moreover, during specific implementation, when the above shock absorber 1 is in an operating state, or during the debugging process of the above 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 blocking the horizontal movement of the adapter plate 14.

[0072] Exemplarily, the above positioning structure 18 may specifically be a dowel pin.

[0073] Exemplarily, in the above shock absorber 1, the number of the positioning structures 18 may be multiple, the number of the second positioning holes 143 may be multiple, and the number of the third positioning holes 112 may be multiple. The multiple third positioning holes 112 may correspond to the multiple positioning structures 18 one by one. And each positioning structure 18 may be specifically configured to insert into the corresponding third positioning hole 143 through the corresponding second positioning hole 112 when the shock absorber 1 is in a non-operating state.

[0074] Exemplarily, as Figures 11 to 13 shown, in the above shock absorber 1, the number of the second positioning holes 143 may specifically be two, and the two second positioning holes 143 may be respectively arranged in the opposite side edge areas of the adapter plate 14.

[0075] Exemplarily, as Figures 11 to 13 shown, in the above shock absorber 1, the orthographic projection of the adapter plate 14 on the horizontal plane may be completely covered by the orthographic projection of the bottom plate 11 on the horizontal plane, and the area of the orthographic projection of the adapter plate 14 on the horizontal plane may be smaller than the area of the orthographic projection of the bottom plate 11 on the horizontal plane.

[0076] In the above embodiment, as 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] In some examples, such as Figures 8 to 10 shown, in the above passive vibration damping assembly 13, the upper limit structure 132 may include an upper limit plate 1321, and the upper limit plate 1321 is fixedly arranged on one side of the top plate 12 facing the bottom plate 11. Exemplarily, the upper limit plate 1321 may be connected to one side of the top plate 12 facing the bottom plate 11 by screws and may be arranged parallel to the horizontal plane.

[0082] Moreover, in specific implementation, in the above passive vibration damping assembly 13, the upper limit plate 1321 of the upper limit structure 132 may have a first surface (i.e., the upper surface) facing away from the lower limit structure 133 (for example, the lower limit plate 1331) and a second surface (i.e., the lower surface) facing the lower limit structure 133 (for example, the lower limit plate 1331). And, the upper limit structure 132 may further include a first protrusion, the first protrusion may be arranged in 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 abutted against the second surface of the upper limit plate 1321, so as to realize the positioning of the upper end of the spring 131 by the upper limit structure 132.

[0083] In the above passive vibration damping assembly 13, the lower limit plate 1331 of the lower limit structure 133 may have a first surface (i.e., the lower surface) facing away from the upper limit structure 132 (for example, the upper limit plate 1321) and a second surface (i.e., the upper surface) facing the upper limit structure 132 (for example, the upper limit plate 1321). And, the lower limit structure 133 may further include a second protrusion 1333, the second protrusion 1333 may be arranged in the middle area of the second surface of the lower limit plate 1331, and the two opposite ends (i.e., the top end and the bottom end) 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 abutted against the second surface of the upper limit plate 1321 and the second surface of the lower limit plate 1331, so as to realize the positioning of the spring 131 between the upper limit structure 132 and the lower limit structure 133.

[0084] Specifically, as Figures 8 to 10 shown, a through hole may be provided in the middle area of the second surface (i.e., the lower surface) of the lower limit plate 1331 of the lower limit structure 133, and the through hole penetrates through the lower limit plate 1331 and the second protrusion 1333. And, 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 limit plate 1331 and the upper limit plate 1321, and the bottom end of the spring 131 may be sleeved on the support rod 1332 extending into this area, so as to realize that the support rod 1332 passes through the lower limit plate 1331 and the second protrusion 1333 and plays a supporting role for the spring 131.

[0085] Thus, 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). After lifting to an appropriate height, the gravity of the load and the top plate 12 can be balanced by the compression reaction force of the spring 131. Then, the height of the lower limit plate 1331 relative to the bottom plate 11 can be further fine-tuned to enable the load and the top plate 12 to reach the designed working height. After that, the vertical vibration and the 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 both a vertical vibration isolation role and a horizontal vibration isolation role.

[0086] In some embodiments, in order to reduce the torsion of the spring 131 during the process of compressing the spring 131 by lifting the lower limit plate 1331 (or the lower limit structure 133) after the load is installed on the top plate 12, so as to reduce the horizontal offset of the load and the top plate 12, as Figures 8 to 10 shown, a first pin hole 13311 may be formed in the edge area of the lower limit plate 1331 of the lower limit structure 133. The passive vibration damping assembly 13 may further include first pins 135. The number of the first pins 135 may be equal to the number of the first pin holes 13311. For example, it may specifically be two. The first pins 135 and the first pin holes 13311 may correspond one by one, and each first pin 135 may be adapted to its corresponding first pin hole 13311. And, when the shock absorber 1 is in a non-working state, the first pins 135 may pass through their corresponding first pin holes 13311 from the side of the lower limit plate 1331 facing away from the bottom plate 11 and then be fixed to the bottom plate 11 and / or the adapter plate 14, so as to reduce 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 pins 135 may be disengaged from their corresponding first pin holes 13311, the bottom plate 11, and the adapter plate 14, so as to ensure that the vibration damping effect of the passive vibration damping assembly 13 is not affected by the first pins 135.

[0087] Moreover, it should be noted that the specific structure of the passive vibration damping assembly 13 is not limited in the embodiments of the present application. The passive vibration damping assembly 13 only needs to provide vertical passive vibration isolation and horizontal passive vibration isolation in the shock absorber 1.

[0088] In the above embodiments, as Figure 8 、 Figure 9 、 Figure 10 、 Figure 15 and Figure 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.

[0089] 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).

[0090] 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, Figure 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.

[0091] For example, Figure 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 .

[0092] 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.

[0093] In some specific embodiments, Figure 17As shown, a limiting structure receiving groove 1911 may be formed in a region of the limiting support base 191 facing the top plate 12 (i.e., the top side) corresponding to the limiting structure 192. The first end (i.e., the bottom end) of the limiting structure 192 may extend into the limiting structure receiving groove 1911 and may be fixed within the limiting structure receiving groove 1911, thereby fixing the limiting structure 192 to the top side of the limiting structure 192.

[0094] Specifically, a first through hole may be formed in a middle region of a surface of the limiting structure 192 facing away from the bottom plate 11 (i.e., the top surface), and the first through hole penetrates the limiting structure 192. And, as Figure 16 shown, the limiting support assembly 19 may further include a locking screw 195. The locking screw 195 may pass through the first through hole and be connected to the limiting support base 191, so that the bottom end of the limiting structure 192 is fixed within the limiting structure receiving groove 1911 by the locking screw 195.

[0095] Exemplarily, as Figure 17 shown, a first groove may be formed in a bottom wall surface of the limiting structure receiving groove 1911, and after passing through the first through hole, the locking screw 195 may be fixedly connected to the first groove by a thread.

[0096] In some specific embodiments, the above-mentioned limiting support assembly 19 may have a working state and a non-working state. Specifically, as Figures 8 to 10 shown, the limiting support assembly 19 may further include a transportation locking screw 193, and the transportation locking screw 193 may be configured to: when the limiting support assembly 19 is in the non-working state, fix the limiting support base 191 to the top plate 12, so as to prevent the limiting support base 191 from moving relative to the top plate 12 in the non-working state, facilitating the transportation of the shock absorber 1 in the non-working state.

[0097] And, when the limiting support assembly 19 is in the working state, the transportation locking screw 193 may be separated from the limiting support base 191 and / or the top plate 12, ensuring that the limiting support base 191 can limit the top plate 12.

[0098] Specifically, as Figure 17 shown, an end portion of the limiting support base 191 facing the top plate 12 (i.e., the top end portion) may be convexly provided with a connecting plate 1912 in the transverse direction, where the transverse direction may be any direction parallel to the horizontal plane. And, a second through hole may be formed in a surface of the connecting plate 1912 facing the bottom plate 11 (i.e., the bottom surface), and the second through hole penetrates the connecting plate 1912. And, when the limiting support assembly 19 is in the non-working state, the transportation 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 limiting support base 191 is fixed to the bottom side of the top plate 12 by the transportation locking screw 193.

[0099] Moreover, in specific implementation, a groove may be formed in the area of the top plate 12 corresponding to the transportation locking screw 193 on one side (i.e., the bottom side) of the bottom plate 11, and after passing through the second through hole, the transportation locking screw 193 may be fixedly connected to the groove by threads.

[0100] Exemplarily, as Figures 8 to 10 shown, the shock absorber 1 may include at least one first limit support assembly 19A and / or at least one second limit support assembly 19B. For example, specifically, it may include two first limit support assemblies 19A and one second limit support assembly 19B. And, for the specific structure of the first limit support assembly 19A, reference may be made to the description of the limit support assembly 19 in the above embodiment, so it will not be elaborated here. The specific structure of the second limit support assembly 19B may be basically the same as that of the first limit support assembly 19A, and the difference between the two may only lie in that the second limit support assembly 19B does not include the transportation locking screw 193, and the resulting difference in the limit support seats 192 included in the two.

[0101] Moreover, it should be noted that the embodiments of the present application do not limit the specific structure, quantity, and distribution position of the limit support assembly 19, as long as the limit support assembly 19 can play a limiting role on the top plate 12 in the shock absorber 1.

[0102] In the above embodiment, as Figures 1 to 7 shown, other functional components in the shock absorber 1 except the passive shock absorption component 13 may include a first motor assembly 21 and / or a second motor assembly 22.

[0103] Specifically, the first motor assembly 21 is disposed in the accommodation space 15 and may include a first stator 211 and a first mover 212. Among them, 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. And, the first mover 212 may be configured to move horizontally relative to the first stator 211 to achieve the horizontal active shock absorption function of the shock absorber 1.

[0104] Exemplarily, as Figures 1 to 7 shown, the first stator 211 included in the first motor assembly 21 may be connected to the adapter plate 14. For example, specifically, it may be connected to the adapter plate 14 through a first adapter 213. The first mover 212 included in the first motor assembly 21 may be connected to the top plate 12. For example, specifically, it may be connected to the top plate 12 by screws, so as to install the first motor assembly 21 in the accommodation space 15 between the adapter plate 14 and the top plate 12.

[0105] Specifically, as Figures 1 to 7 andFigure 18 As shown, the second motor assembly 22 is disposed within the accommodation space 15 and may include a second stator 221 and a second mover 222. Among them, 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. Moreover, the second mover 222 may be configured to move vertically relative to the second stator 221 to achieve the vertical active vibration damping function of the above-mentioned shock absorber 1.

[0106] Exemplarily, as Figures 1 to 7 and Figure 18 shown, the second stator 221 included in the above-mentioned second motor assembly 22 may be connected to the adapter plate 14. For example, specifically, it may be connected to the adapter plate 14 through a second adapter 223. The second mover 222 included in the above-mentioned second motor assembly 22 may be connected to the top plate 12. For example, specifically, it may be connected to the top plate 12 through screws, so as to install the above-mentioned second motor assembly 22 within the accommodation space 15 between the adapter plate 14 and the top plate 12.

[0107] In some specific embodiments, the above-mentioned shock absorber 1 may include one or more first motor assemblies 21. Specifically, as Figures 1 to 7 shown, the above-mentioned shock absorber 1 may specifically include two first motor assemblies 21. Each of the two first motor assemblies 21 may have an independent first adapter 213 for connecting the stator (i.e., the first stator 211) included therein to the adapter plate 14.

[0108] In some specific embodiments, the above-mentioned shock absorber 1 may include one or more second motor assemblies 22. Specifically, as Figures 1 to 7 and Figure 18 shown, the above-mentioned shock absorber 1 may specifically include four second motor assemblies 22. The four second motor assemblies 22 may be divided into two groups. Each group of second motor assemblies 22 may include two second motor assemblies 22, and all the second motor assemblies 22 in the same group may share the same second adapter 223, and the second motor assemblies 22 in different groups may have different second adapters 223. In other words, the stators (i.e., the second stators 221) included in all the second motor assemblies 22 in the same group may be connected to the adapter plate 14 through the same second adapter 223, while the stators included in the 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 within the above-mentioned shock absorber 1.

[0109] In the above embodiments, as Figure 18As shown, other functional components of the shock absorber 1 except the passive shock absorption component 13 may include a displacement sensor assembly 23. The displacement sensor assembly 23 is disposed in the accommodation space 15 and can be used to detect the movement displacement of the top plate 12. Specifically, the displacement sensor assembly 23 may include a mounting bracket 231 and a displacement sensor 232. Among them, the mounting bracket 231 is connected to the adapter plate 14, and the displacement sensor 232 is mounted on the mounting bracket 231.

[0110] Specifically, in the above embodiment where the shock absorber 1 includes the 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, so as to realize the connection between the mounting bracket 231 of the displacement sensor assembly 23 and the adapter plate 14.

[0111] In some specific embodiments, the number of displacement sensors 232 included in the displacement sensor assembly 23 may 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 the preset direction corresponding to it. Among them, the preset direction can be vertical or horizontal.

[0112] Specifically, the number of displacement sensors 232 included in the displacement sensor assembly 23 can be specifically two, denoted as: the first displacement sensor and the second displacement sensor. Among them, the first displacement sensor can be configured to detect the movement displacement of the top plate 12 in the horizontal direction, and the second displacement sensor can be configured to detect the movement displacement of the top plate 12 in the vertical direction. In other words, the first displacement sensor can specifically be a horizontal displacement sensor, and the second displacement sensor can specifically be a vertical displacement sensor.

[0113] In some examples, the displacement sensor assembly 23 further includes a shielding cylinder, and the number of the shielding cylinders and displacement sensors 232 included in the displacement sensor assembly 23 can be equal and correspond one by 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.

[0114] In some examples, the displacement sensor assembly 23 may further include an induction sheet, and the number of the induction sheets and displacement sensors 232 included in the displacement sensor assembly can be equal and correspond one by one. Specifically, in the displacement sensor assembly 23, each induction sheet is fixedly arranged on one side (i.e., the bottom side) of the top plate 12 facing the bottom plate 11 and is relatively spaced from the corresponding displacement sensor 232 along the corresponding preset direction.

[0115] In some specific embodiments, such as Figure 18 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. Further, the shock absorber 1 may further include a controller assembly 24, the controller assembly 24 is disposed in the accommodation 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.

[0116] 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. Thus, 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 can be changed, thereby achieving the shock absorption effect of the shock absorber 10.

[0117] Exemplarily, such as Figures 1 to 7 shown, the shock absorber 1 may further include a protective side plate 25, the protective side plate 25 is disposed around the outer wall of the accommodation space 15 between the top plate 12 and the adapter plate 14 to protect other functional components (such as the controller 141) in the accommodation space 15.

[0118] Specifically, the protective side plate 25 may be connected to the adapter plate 14 and other functional components in the accommodation space 15. For example, it may be connected to the adapter plate 14 and other functional components in the accommodation space 15 by screws, thereby ensuring the firm installation of the protective side plate 25.

[0119] Exemplarily, such as Figure 18 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.

[0120] Specifically, such as Figure 18 shown, the number of the speed sensors 26 included in the displacement sensor assembly 1 may be specifically two, denoted as: a first speed sensor 26A and a second speed sensor 26B. Wherein, the first speed sensor 26A may be configured to detect the movement speed of the top plate 12 in the horizontal direction, and the second speed sensor 26B may be configured to detect the movement speed of the top plate 12 in the vertical direction. Further, the controller 241 may be specifically configured to: control the operation of the first motor assembly 17 and / or the second motor assembly 18 according to the detection result of the displacement sensor 232 and / or the speed sensor 26.

[0121] In the above embodiment, the shock absorber 10 may be used as a shock absorption table for shock absorption of precision equipment such as semiconductor equipment and / or precision machine tools.

[0122] As can be seen from the above, the shock absorber provided in this embodiment includes a bottom plate and a top plate that are relatively spaced apart in a first direction, a passive shock absorption component, and an adapter plate. Among them, the passive shock absorption component is disposed between the bottom plate and the top plate, and the two opposite ends of the passive shock absorption component in 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 shock absorption component. The adapter plate is disposed on the bottom plate in a position-adjustable manner, and there is a receiving space between the adapter plate and the top plate. The receiving space is used to receive other functional components, so that other functional components except the passive shock absorption component can be installed on the adapter plate in the receiving space between the adapter plate and the top plate, rather than directly installed on the bottom plate. Furthermore, during the debugging process of the shock absorber, if the passive shock absorption component twists, causing the top plate to horizontally shift or twist relative to the bottom plate, by adjusting the position of the adapter plate on the bottom plate, the translational adjustment of other functional components in the horizontal plane can be achieved, ensuring that the abnormal operation problems of other functional components that may be caused by the horizontal shift of the top plate are solved. The adjustment method is simple and efficient, thus reducing the debugging difficulty of the shock absorber and reducing the 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.

[0123] An embodiment of the present application further provides a shock absorption system, which includes the shock absorber of any of the above embodiments. Specifically, in this shock absorption system, the shock absorber includes a bottom plate and a top plate that are relatively spaced apart in a first direction, a passive shock absorption component, and an adapter plate disposed between the bottom plate and the top plate. Among them, one end of the passive shock absorption component in the first direction is connected to the bottom plate, and the other end of the passive shock absorption component in the first direction is connected to the top plate. The adapter plate is spaced apart from the passive shock absorption component, and the adapter plate is disposed on the bottom plate in a position-adjustable manner, and there is a receiving space between the adapter plate and the top plate. The receiving space is used to install other functional components.

[0124] Specifically, the shock absorption system may further include a load, and the load may be fixed above the top plate of the shock absorber, so as to achieve shock absorption of the load.

[0125] Exemplarily, the load may be a semiconductor device, a precision machine tool, or other precision equipment.

[0126] In some embodiments, the number of shock absorbers included in the above shock absorption system may be multiple (for example, at least three), and the above shock absorption system may further include a workbench installed above the multiple shock absorbers, so that the height of the workbench at the position 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 keep the workbench always in a horizontal state.

[0127] It should be noted that for the vibration damping system provided by the embodiments of the present application, since the shock absorber provided by the embodiments of the present application is provided, the beneficial effects achievable by any of the shock absorbers provided by the embodiments of the present application can be realized. For details, refer to the previous embodiments and will not be elaborated herein.

[0128] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
