For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] This embodiment provides a support device for a sports table, such as Figure 1 As shown, it includes a base 100, an elastic reset component 200, a bearing seat 300 and a supporting component 400, wherein the elastic reset component 200 is connected to the base 100 and can be elastically deformed; the bearing seat 300 is supported on the upper part of the elastic reset component 200; Figure 3 As shown, the support assembly 400 includes a mover module 410 and a stator module 420 which are arranged with a gap, and the bottom end of the stator module 420 is connected to the base 100, as shown in FIG. Figure 3 and Figure 1 As shown, the mover module 410 is connected to the elastic reset assembly 200 or the bearing seat 300 , and the mover module 410 and the stator module 420 interact with each other to form an upward magnetic driving force on the mover module 410 .

[0032] In the support device provided in this embodiment, there is a large Z-direction magnetic field force between the mover module 410 and the stator module 420 of the support assembly 400 in the Z-direction, that is, the up-down direction, corresponding to the large stiffness in the Z-direction. Specifically, the mover module 410 and the stator module 420 can interact with each other to form an upward magnetic driving force on the mover module 410. Figure 2 As shown, when the mover module 410 is connected to the elastic reset assembly 200, the elastic reset assembly 200 can apply an upward supporting force to the bearing seat 300, such as Figure 1 and Figure 3 As shown, when the mover module 410 is directly connected to the bearing seat 300, it can directly apply an upward supporting force to the bearing seat 300, thereby achieving high-rigidity support for the bearing seat 300 in the Z direction, and correspondingly ensuring the stable height of the bearing seat 300 in the Z direction during operation; at the same time, the mover module 410 is relatively fixed to the bearing seat 300, and the stator module 420 is relatively fixed to the base 100. There is a small XY-direction magnetic field force between the mover module 410 and the stator module 420 in the XY direction, that is, in the horizontal plane, corresponding to a small rigidity in the XY direction. When the bearing seat 300 is relative to the base When the platform 100 is displaced in the horizontal direction, the mover module 410 and the stator module 420 move relative to each other in the XY direction, and a certain magnetic damping force is generated between the two. While ensuring that the mover module 410 and the stator module 420 have a large stroke in the horizontal plane, that is, the support base 300 has a large stroke in the horizontal direction relative to the base 100, it can also dissipate the vibration energy of the support base 300 in the horizontal direction. By isolating the horizontal movement of the support base 300, its movement posture can be controlled and the stability of the horizontal movement of the support base 300 can be improved.

[0033] At the same time, on the basis of the high rigidity support of the support assembly 400 to the bearing seat 300 in the Z direction, the elastic reset assembly 200 can also provide auxiliary support to the bearing seat 300 in the Z direction to further ensure the high stability of the bearing seat 300 in the Z direction; preferably, the elastic reset assembly 200 only has elastic deformation in the XY direction, that is, the horizontal direction. In addition, when the bearing seat 300 moves in the horizontal direction, the elastic reset assembly 200 is elastically deformed in the corresponding direction under the driving action of the bearing seat 300, thereby playing a damping role in the movement of the bearing seat 300, and correspondingly can also play a dissipation role in the vibration energy of the bearing seat 300 in the horizontal direction, and further improve the stability of the bearing seat 300 in the horizontal direction by isolating the vibration of the bearing seat 300 in the horizontal direction; in addition, after the elastic reset assembly 200 is elastically deformed, it will apply an elastic force to the bearing seat 300 to drive it to return to its original position, so as to control the movement posture of the bearing seat 300 to quickly self-recover.

[0034] In the support device of this embodiment, the support component 400 and the elastic reset component 200 can jointly provide high-rigidity and stable support in the Z direction, vibration isolation in the horizontal direction, and posture reset for the bearing seat 300, so that the bearing seat 300 can achieve small rigidity and sufficient travel in the horizontal plane, large rigidity and micro-displacement in the load-bearing direction, thereby ensuring stable and high-precision processing of the workpiece carried on the bearing seat 300.

[0035] Optionally, in this embodiment, if Figure 3 and Figure 2 As shown, the stator module 420 has a receiving channel 424, and the movable module 410 includes a middle seat body 411 penetrating the receiving channel 424, and the end of the middle seat body 411 extending out of the receiving channel 424 is connected with a connecting component, and the connecting component is connected to the elastic reset assembly 200 or the bearing seat 300. The bottom of the stator module 420 is fixed to the base 100, and the middle seat body 411 is movably inserted in the receiving channel 424 and interacts with the stator module to form an upward magnetic driving force, and the magnetic driving force is transmitted to the bearing seat 300 through the connecting component, so as to realize the rigid support of the bearing seat 300 in the Z direction; at the same time, there is an accommodating gap between the middle seat body 411 and the inner wall of the receiving channel 424, so as to ensure that the middle seat body 411 moves with the bearing seat 300 in the horizontal direction, and correspondingly ensures the large stroke movement of the bearing seat 300 in the horizontal direction.

[0036] Specifically, in this embodiment, Figure 2 and Figure 3As shown, the stator module 420 includes a lower seat body 421 fixed on the base 100, an upper seat body 423 located above the lower seat body 421 and a support body 422 supported therebetween, and the upper seat body 423, the support body 422 and the lower seat body 421 together form a accommodating channel 424; wherein, the middle seat body 411 and the lower seat body 421 interact with each other to form an upward magnetic driving force on the middle seat body 411, and the middle seat body 411 and the upper seat body 423 interact with each other to form an upward magnetic driving force on the middle seat body 411. The stator module 420 is fixed to the base 100 through the lower seat 421, and the support body 422 is supported between the lower seat 421 and the upper seat 423 to form a stable accommodating channel 424 between the two; the middle seat 411 is movably inserted into the accommodating channel 424 and there is an accommodating gap between the upper seat 423 and the lower seat 421 to ensure that the middle seat 411 moves stably relative to the upper seat 423 and the lower seat 421 in the horizontal direction, wherein the middle seat 411 and the lower seat 421 are mutually magnetically acted on to make the lower seat The body 421 applies an upward magnetic repulsive force to the middle seat body 411, which correspondingly forms an upward magnetic urging force on the middle seat body 411; similarly, the middle seat body 411 and the upper seat body 423 act on each other through the magnetic field, so that the upper seat body 423 applies an upward magnetic attraction force to the middle seat body 411, which correspondingly forms an upward magnetic urging force on the middle seat body 411; the middle seat body 411 is connected to the elastic reset assembly 200 or the supporting seat 300 through a connecting component, so as to transmit the magnetic urging force to the supporting seat 300, thereby achieving stable support for the supporting seat 300.

[0037] Of course, in some other embodiments, only the middle seat body 411 and the lower seat body 421 may interact with each other to form an upward magnetic driving force on the middle seat body 411, or only the middle seat body 411 and the upper seat body 423 may interact with each other to form an upward magnetic driving force on the middle seat body 411.

[0038] In the case where the middle seat body 411 and the upper seat body 423 interact to form an upward magnetic driving force on the middle seat body 411, one of the middle seat body 411 and the upper seat body 423 is a magnet, and the other is a magnetic attraction member that can be magnetically attracted to the magnet. Specifically, the upper seat body 423 can be made of a permanent magnet, a superconducting magnet or an electromagnet, and the lower seat body 421 can be made of iron, Permalloy, etc. that can be magnetically attracted to a permanent magnet or an electromagnet; or the lower seat body 421 can be made of a permanent magnet, a superconducting magnet or an electromagnet, and the upper seat body 423 can be made of iron, Permalloy, etc. that can be magnetically attracted to a permanent magnet or an electromagnet. In the case, the magnetic attraction member can be a whole plate or a stack of thin sheets made of a material with low eddy current loss and high magnetic permeability.

[0039] Among them, when permanent magnets, superconducting magnets, and metal magnetic suction parts are used in the upper seat body 423, the middle seat body 411, and the lower seat body 421, the support assembly 400 has a simple structure, does not require external power, and produces less wear during use. In addition to being used in atmospheric environments, it can also be used in vacuum environments with higher requirements.

[0040] In the case where the middle seat body 411 and the lower seat body 421 interact to form an upward magnetic driving force on the middle seat body 411, one of the middle seat body 411 and the lower seat body 421 is a first magnet and the other is a second magnet, and a magnetic repulsion force away from each other is generated between the first magnet and the second magnet. Specifically, the first magnet and the second magnet can be permanent magnets or electromagnets, and the magnetic poles facing each other are the same to generate a magnetic repulsion force on each other.

[0041] Specifically, in this embodiment, Figure 3 As shown, the connecting component includes two support plates 412 and a connecting plate 413 located above the upper seat body 423. The bottom ends of the two support plates 412 are connected one-to-one with the two protruding ends of the middle seat body 411, and the top ends are connected one-to-one with the two ends opposite to the connecting plates 413. The connecting plate 413 is connected to the elastic reset assembly 200 or the supporting seat 300. On the one hand, the middle seat body 411 can stably transmit the magnetic driving force to the connecting plate 413 through the two support plates 412 at both ends, thereby improving the force stability of the middle seat body 411, and correspondingly ensuring the position stability of the middle seat body 411 in the accommodating channel 424, thereby ensuring the stable magnetic field effect of the middle seat body 411 on the upper seat body 423 and the lower seat body 421, and the Z-direction stable support and horizontal damping vibration reduction of the supporting seat 300 by the connecting plate 413; on the other hand, the connecting plate 413, the two support plates 412 and the middle seat body 411 of the mover module 410 are connected in an annular shape, and the upper seat body 423, the support body 422 and the lower seat body 421 of the stator module 420 are connected in an annular shape, and the annular shapes of the two are nested, thereby ensuring the relative position connection of the two, and no additional assembly of the two is required during assembly, thereby improving the assembly convenience of the support component 400.

[0042] In this embodiment, Figure 2As shown, the elastic reset assembly 200 includes two flexible hinges 210, and the flexible hinge 210 includes a first flexible segment 211 extending along a first direction, and both ends of the first flexible segment 211 are connected to a second flexible segment 212 extending along a second direction, and the two second flexible segments 212 are located on the same side of the first flexible segment 211, and the ends of the second flexible segments 212 facing away from the first flexible segment 211 are connected to the base 100; the second flexible segments 212 of the two flexible hinges 210 are arranged one by one and facing each other, and the supporting seat 300 is supported on the upper part of the two first flexible segments 211. Here is one specific form of the elastic reset component 200, wherein the first flexible segment 211 can undergo elastic deformation in a direction approximately perpendicular to the first direction, and the second flexible segment 212 can undergo elastic deformation in a direction approximately perpendicular to the second direction, and the first flexible segment 211 and the second flexible segment 212 are connected and the extension directions of the two are cross-arranged, so that the flexible hinge 210 can undergo elastic deformation in various directions in the horizontal direction; the two flexible hinges 210 have a total of two first flexible segments 211 and four second flexible segments 212, wherein the two first flexible segments 211 both extend in the first direction and are arranged in parallel at intervals, and the four second flexible segments 212 both extend in the second direction and are arranged in parallel at intervals in groups of two.

[0043] When in use, the end of the second flexible section 212 of each flexible hinge 210 away from the first flexible section 211 is connected to the base 100, and there is an adjustment gap between the first flexible section 211 and the second flexible section 212 at the parts different from the ends and the base 100 to allow them to elastically deform relative to the base 100; when the supporting seat 300 is displaced in a third direction approximately perpendicular to the first direction, the two first flexible sections 211 are pulled by the base 100 to elastically deform in the third direction to reduce the vibration energy of the supporting seat 300 moving in the third direction. The first flexible section 211 and the second flexible section 212 can dissipate the vibration energy of the bearing seat 300 in the fourth direction and generate an elastic restoring force in the third direction on the bearing seat 300 to drive the bearing seat 300 to recover its motion posture. Similarly, when the bearing seat 300 is displaced in a fourth direction approximately perpendicular to the second direction, the four second flexible sections 212 are elastically deformed in the fourth direction under the pulling action of the base 100 to dissipate the vibration energy of the bearing seat 300 in the fourth direction and generate an elastic restoring force in the fourth direction on the bearing seat 300 to drive the bearing seat 300 to recover its motion posture. Similarly, when the bearing seat 300 is displaced in other directions relative to the base 100, the first flexible section 211 and the second flexible section 212 can be coupled and elastically deformed at the same time to dissipate the vibration energy of the bearing seat 300 and generate an elastic restoring force in the opposite direction on the bearing seat 300 to drive the bearing seat to quickly recover its original motion posture.

[0044] Among them, the four second flexible segments 212 are arranged opposite to each other and located between the two first flexible segments 211. On the basis of realizing elastic deformation in the fourth direction, the volume of the elastic reset component 200 can be effectively reduced, and the volume of the entire support device and its occupied space can be correspondingly reduced. In addition, the bearing seat 300 is overlapped between the two parallel first flexible segments 211. Accordingly, the two first flexible segments 211 can support the two ends of the bearing seat 300, thereby improving its support stability for the bearing seat 300.

[0045] Specifically, Figure 4 As shown, the first flexible segment 211 and the second flexible segment 212 may include a multi-segment main body portion 213a and a flexible joint portion 213b connected between two adjacent main body portions 213a, wherein the flexible joint portion 213b may be in the form of a leaf spring, a U-shaped groove, etc. to maintain the relative position of the two adjacent main body portions 213a and enable relative rotation between the two, thereby achieving elastic deformation of the first flexible segment 211 in the third direction and elastic deformation of the second flexible segment 212 in the fourth direction.

[0046] Optionally, in this embodiment, if Figure 2 As shown, the base 100 (not shown in the figure) is fixed with four columns 500, and the columns 500 include a connecting portion 510 and a supporting portion 520 from top to bottom, and the ends of the four second flexible segments 212 away from the corresponding first flexible segments 211 are connected to the connecting portions 510 of the four columns 500 in a one-to-one correspondence. The second flexible segment 212 is specifically fixed to the base 100 through the columns 500, wherein the supporting portion 520 of the column 500 can support the second flexible segment 212 and the first flexible segment 211 and the base 100 to have an adjustment gap, so as to ensure the elastic deformation of the first flexible segment 211 in the third direction and the elastic deformation of the second flexible segment 212 in the fourth direction.

[0047] Specifically, in this embodiment, Figure 2 As shown, a connecting beam 214 may be connected between the two first flexible segments 211. The connecting beam 214 is a rigid beam, which is connected between the two first flexible segments 211 and can limit the two first flexible segments 211, thereby improving the torsional rigidity of the first flexible segments 211, correspondingly reducing the torsional deviation of the bearing seat 300, and further improving the position stability of the bearing seat 300. Preferably, the first direction and the second direction are approximately perpendicular, and the connecting beam 214 can extend along the second direction, and the two ends are respectively connected to the middle positions of the two first flexible segments 211.

[0048] In this embodiment, there may be multiple support assemblies 400, and the mover modules 410 of the multiple support assemblies 400 are all connected to the bottom surface of the connecting beam 214, and are arranged at intervals along the length direction of the connecting beam 214. The multiple support assemblies 400 can support different parts of the connecting beam 214, so as to evenly transfer the magnetic driving force to the connecting beam 214, and the connecting beam 214 then transfers the magnetic driving force to the first flexible segment 211 through both ends, and the first flexible segment 211 then transfers the magnetic driving force to the bearing seat 300, so as to realize the upward support of the bearing seat 300.

[0049] Optionally, in this embodiment, if Figure 1 As shown, a damping assembly 600 is also connected between the bearing seat 300 and the base 100, and the damping assembly 600 is used to damp the vibration of the bearing seat 300 in the horizontal direction. The fixed part 610 of the damping assembly 600 is fixedly connected to the base 100, and the moving part 620 is fixedly connected to the bearing seat 300. When the bearing seat 300 is displaced in the horizontal direction, the moving part 620 of the damping assembly 600 is driven to move synchronously with it. In this process, the fixed part 610 produces a damping effect on the moving part 620 to hinder its movement, and correspondingly plays a damping role on the bearing seat 300, so as to dissipate the vibration of the bearing seat 300 in the horizontal direction, thereby further improving the stability of the bearing seat 300 in the horizontal direction and achieving high flexibility of horizontal vibration isolation.

[0050] Specifically, the damping components 600 may be multiple groups, and the multiple groups of damping components 600 are dispersedly arranged around the bearing seat 300 or on two opposite sides; Figure 2 As shown, there are four groups of damping components 600, two of which are located on one side of the support base 300 in the X direction, and the other two are located on the other side of the support base 300 in the X direction. Specifically, the damping components 600 can use drift management motors or electromagnetic eddy current damping structures.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
