Description

Technical Field

[0001] This application relates to the field of resonant dispersion technology, and in particular to a resonant device for dispersing lithium battery materials. Background Technology

[0002] Lithium-ion battery materials often contain solid or solid-liquid slurry materials that are difficult to disperse. However, it is necessary to achieve uniform dispersion of the main materials, additives, conductive agents, binders, and dispersants in the electrode materials. Existing dispersion structures cannot achieve this. Mainstream equipment such as planetary ball mills, high-speed shear dispersers, and grinding dispersers basically combine the use of dispersants with mechanical dispersion, which can easily introduce impurities and cause pollution. The strong shear force may damage the existing material structure, and the generated heat can easily cause side reactions that change the material properties. In order to solve the problems of the above equipment, this application provides a resonance device that can achieve efficient and uniform dispersion of lithium-ion battery materials, avoid the introduction of pollution sources, and reduce the occurrence of particle agglomeration. Summary of the Invention

[0003] To address the aforementioned issues, this application provides a resonant device for dispersing lithium battery materials.

[0004] The resonant device for dispersing lithium battery materials provided in this application adopts the following technical solution:

[0005] A resonant device for dispersing lithium battery materials includes a support structure, a load structure, an excitation structure, and a resonant structure. The support structure provides elastic support, and the resonant structure is mounted on top of the support structure. The excitation structure is elastically connected to the resonant structure, and the top of the excitation structure is connected to the load structure, which provides a container for material dispersion. The excitation structure includes an excitation source. When the excitation source vibrates, the excitation force is transmitted to the resonant structure, which amplifies the excitation force. Synchronously, the elastic support of the support structure further amplifies the excitation force and transmits it to the load structure, thereby dispersing the material within the load structure.

[0006] By adopting the above technical solution, the lithium battery material is located within the load structure. When the excitation source generates an excitation force, it is transmitted to the resonant structure, which amplifies the excitation force to form a third layer of elastic resonance. Thus, by utilizing the first layer of elastic resonance of the support structure, the second layer of elastic resonance between the excitation structure and the resonant structure, and the third layer of elastic resonance of the resonant structure, the excitation force generated by the excitation source is continuously amplified and finally transmitted to the load structure, making the excitation force sufficient to disperse the material within the load structure. At the same time, no contaminant source is introduced into the load structure during the dispersion process, ensuring the purity of the lithium battery material.

[0007] Optionally, the support structure includes a base, a first elastic part, a support guide part, and a support seat; several support seats are provided and distributed on the top surface of the base, and each support seat has a support guide opening; the first elastic part is installed in a one-to-one correspondence with the support seat, and the resonant structure is installed on the top of the first elastic part; a support guide part is provided between the first elastic part and the support seat, and one end of the support guide part is connected to the bottom surface of the resonant structure, and the other end passes through the first elastic part and is inserted into the support guide opening.

[0008] By adopting the above technical solution, the base provides a stable base layer, multiple first elastic parts provide support for the resonance structure, and the first elastic parts are connected by the support guide and the support guide port to prevent the first elastic parts from shifting or twisting, thus providing a stable first layer of elastic resonance effect.

[0009] Optionally, the load structure includes a load cylinder, a dispersion disk, and connecting rods; the load cylinder is installed on the top surface of the dispersion disk, and several connecting rods are provided, with one end distributed on the bottom surface of the dispersion disk and the other end connected to the excitation structure.

[0010] By adopting the above technical solution, the lithium battery material to be dispersed is contained in the load cylinder and connected by the dispersion disk. The dispersion disk expands the bearing range, and the excitation force is stably transmitted to the load cylinder through several connecting rods, so that the load structure can effectively disperse the internal lithium battery material under the action of the excitation force.

[0011] Optionally, the excitation structure also includes an upper excitation platform, a lower excitation platform, a second elastic part, and an excitation guide part; the bottom surface of the upper excitation platform and the top surface of the lower excitation platform are provided with several mounting grooves respectively; one end of the second elastic part is located in the mounting groove of the upper excitation platform, and the other end is located in the mounting groove of the lower excitation platform; an excitation guide port is also provided in the mounting groove; the top end of the excitation guide part is connected to the upper excitation platform, and the bottom end is inserted into the lower excitation platform through the resonant structure.

[0012] By adopting the above technical solution, the excitation source is installed on the upper and lower excitation platforms, and the excitation force generated by the excitation source is transmitted by the second elastic part. At the same time, the excitation force is amplified and transmitted to the resonant structure. The excitation guide part provides the anti-displacement effect of the second elastic part, ensuring the stability of the excitation force transmission.

[0013] Optionally, the resonance structure includes a first resonance platform, a resonance seat, a third elastic part, a second resonance platform, and a resonance guide part; several resonance seats are provided and distributed on the top surface of the first resonance platform; the third elastic part is connected to the resonance seat in a one-to-one correspondence, and the resonance seat has a resonance guide port; the second resonance platform is connected to the third elastic part, and the second resonance platform has an installation port corresponding to the position of the resonance seat; the resonance guide part is inserted into the resonance guide port and extends through the installation port in a direction away from the first resonance platform; the second resonance platform also has several excitation ports, and the second elastic part is connected to the second resonance platform through the excitation ports.

[0014] By adopting the above technical solution, the second elastic part is connected to the second resonance stage through the excitation port, so that the second elastic part can transmit the excitation force to the second resonance stage. The second resonance stage is connected to the third elastic part, so the third elastic part can receive the excitation force transmitted by the second resonance stage to amplify the excitation force. Then, through the resonance seat and the first resonance stage, the excitation force is transmitted to the first elastic part, thereby realizing multi-layer amplification of the excitation force to improve the dispersion of lithium battery materials.

[0015] Optionally, both the third elastic part and the second elastic part are divided into two segments, with the first segment located above the second resonance platform and the second segment located below the second resonance platform.

[0016] By adopting the above technical solution, after the second elastic part and the third elastic part are divided into two segments, the second elastic part of the two segments can stably and amplify the transmission of excitation force, and after the third elastic part is divided into two segments, it can also further amplify the excitation force.

[0017] Optionally, the resonant structure further includes a fixed rod and a first threaded portion; the fixed rod is installed on the first resonant platform and has an external thread on its top; the resonant guide portion has a through-hole, and the outer diameter of the fixed rod is smaller than the inner diameter of the through-hole; the third elastic portion has a resonant cover at the end away from the first resonant platform, and the resonant cover has a sliding opening, so that the end of the fixed rod with the external thread extends away from the first resonant platform through the through-hole and the sliding opening; the first threaded portion is screwed to the external thread of the fixed rod and abuts against the resonant cover.

[0018] By adopting the above technical solution, the first threaded part continuously pushes the resonance cover downward through the external thread of the fixed rod, thereby causing the resonance cover to press down on the third elastic part, which changes the deformation or expansion of the third elastic part, thereby adjusting the amplification of the excitation force.

[0019] Optionally, a pivot groove is provided on one surface of the resonant cover, and a pivot ring is provided at one end near the third elastic part. The pivot ring is pivotally connected to the pivot groove, so that when the first threaded part rotates along the pivot groove through the pivot ring, it synchronously drives the resonant cover to move along the fixed rod.

[0020] By adopting the above technical solution, the first threaded part rotates along the pivot groove through the pivot ring. During the rotation, the first threaded part rises and falls along the external thread of the fixed rod, and simultaneously drives the resonance cover to move along the fixed rod through the pivot ring, so as to adjust the expansion and contraction of the third elastic part.

[0021] The optional fixing rod between the first resonance platform and the base is further provided with a second threaded part, a resonance connecting plate, and a fourth elastic part; the second threaded part is screwed to the fixing rod, and a pivot ring is provided on the side near the first resonance platform; the resonance connecting plate has a sliding opening for the fixing rod to pass through and a pivot groove for the pivot ring to pivotally connect; one end of the fourth elastic part is connected to the bottom surface of the first resonance platform, and the other end is connected to the resonance connecting plate; the fixing rod is divided into external threads with the center point in the length direction as the dividing line, and the thread directions of the external threads on both sides of the dividing line are opposite; the fixing rod is slidably connected to the first resonance platform; the fixing rod extends through the first resonance platform and the resonance connecting plate to the support structure and is pivotally connected to the support base.

[0022] By adopting the above technical solution, when the fixed rod rotates, the first threaded part and the second threaded part are subjected to opposite driving forces, and the two move relative to each other or move in opposite directions, so that the two unfold synchronously, and the second elastic part, the third elastic part and the fourth elastic part are extended or contracted, thereby further realizing the adjustment of the expansion and contraction of the elastic part.

[0023] Optionally, several fixed rods are distributed on the base with the load structure as the axis, and the fixed rods are equipped with linkage gears. All linkage gears are engaged with linkage gear rings, and a single linkage gear ring is engaged with all linkage gears.

[0024] By adopting the above technical solution, simply rotating the linkage gear ring or any linkage gear can drive all the fixed rods to rotate, thereby achieving synchronous adjustment of the extension and contraction of the second, third, and fourth elastic parts to adjust the vibration effect.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The lithium battery material is located within the load structure. When the excitation source generates an excitation force, it is transmitted to the resonant structure, which amplifies the excitation force to form a third layer of elastic resonance. Thus, by utilizing the first layer of elastic resonance of the support structure, the second layer of elastic resonance between the excitation structure and the resonant structure, and the third layer of elastic resonance of the resonant structure, the excitation force generated by the excitation source is continuously amplified and finally transmitted to the load structure, making the excitation force sufficient to disperse the lithium battery material within the load structure. At the same time, the load structure does not introduce any contaminants during the dispersion process, ensuring the purity of the lithium battery material.

[0027] 2. The base provides a stable base layer, and multiple first elastic parts provide support for the resonance structure. The first elastic parts are connected by the support guide and the support guide port to prevent the first elastic parts from shifting or twisting, thus providing a stable first layer of elastic resonance effect.

[0029] 4. The excitation source is installed on the upper and lower excitation platforms, and the excitation force generated by the excitation source is transmitted by the second elastic part. At the same time, the excitation force is amplified and transmitted to the resonant structure. The excitation guide part provides the anti-displacement effect of the second elastic part to ensure the stability of the excitation force transmission. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail below.

[0045] This application discloses a resonant device for dispersing lithium battery materials.

[0046] A resonant device for dispersing lithium battery materials, reference Figure 1 As shown, it includes a support structure 1, a load structure 2, an excitation structure 3, and a resonance structure 4; the support structure 1 provides elastic support, and the resonance structure 4 is installed on top of the support structure 1 to provide the first layer of elastic resonance using the elastic support of the support structure 1.

[0047] The excitation structure 3 and the resonance structure 4 are elastically connected to form a second layer of elastic resonance. The top of the excitation structure 3 is connected to the load structure 2, which provides a container for material dispersion, that is, the lithium battery material to be dispersed is placed in the load structure 2.

[0048] The excitation structure 3 includes an excitation source 31, which can be composed of a vibration motor, a servo motor, an eccentric block, and an encoder. The number of excitation sources 31 is even, and they are arranged in pairs in parallel and opposite directions, i.e., in opposite directions. Therefore, at least two sets are provided so that when the excitation source 31 generates vibration, it can cancel the excitation force in the horizontal direction and control the amplitude of the excitation force through the phase difference.

[0049] After the excitation source 31 generates the excitation force, it is transmitted to the resonance structure 4, which amplifies the excitation force to form a third layer of elastic resonance. Thus, by utilizing the first layer of elastic resonance of the support structure 1, the second layer of elastic resonance of the excitation structure 3 and the resonance structure 4, and the third layer of elastic resonance of the resonance structure 4, the excitation force generated by the excitation source 31 is continuously amplified and finally transmitted to the load structure 2, so that the excitation force is sufficient to disperse the material in the load structure 2. At the same time, the load structure 2 does not introduce any pollution source during the dispersion process, ensuring the purity of the lithium battery material.

[0050] In some embodiments, reference Figure 2 As shown, the support structure 1 includes a base 11, a first elastic part 12, a support guide part 13, and a support seat 14. The base 11 can be a rectangular or circular panel, and a support foot can be provided at the bottom. Several support seats 14 are provided and distributed on the top surface of the base 11. The support seats 14 are provided with support guide openings (not shown in the figure). The support seats 14 can be fixed to the top surface of the base 11 using a cylindrical structure. The number of support seats 14 is determined according to the requirements. In this embodiment, four sets of support seats 14 are provided as an example.

[0051] The first elastic part 12 is installed in a one-to-one correspondence with the support base 14. The resonance structure 4 is installed on the top of the first elastic part 12. The first elastic part 12 can be a first spring. In this embodiment, there are four sets of support bases 14. Therefore, there are also four sets of first elastic parts 12. Each set of first elastic parts 12 is installed on the top of a support base 14. The resonance structure 4 is fixed on the top of the four sets of first elastic parts 12. The first elastic part 12 provides the first layer of elastic resonance of the resonance structure 4.

[0052] A support guide portion 13 is provided between the first elastic part 12 and the support base 14. The support guide portion 13 can be a support guide rod. One end of the support guide portion 13 is connected to the bottom surface of the resonant structure 4, and the other end passes through the first elastic part 12 into the support guide opening and is inserted into the support guide opening. The function of the support guide portion 13 is to limit the lateral displacement of the first elastic part 12, prevent the first elastic part 12 from deflecting or twisting during operation, and ensure that the first elastic part 12 is only compressed or stretched along the axial direction, thereby maintaining the stability of the excitation force transmission.

[0053] Specifically, the base 11 provides a stable base layer, multiple first elastic parts 12 provide support for the resonance structure 4, and the first elastic parts 12 are connected by the support guide part 13 and the support guide port to prevent the first elastic parts 12 from shifting or twisting, thus providing a stable first layer of elastic resonance effect.

[0054] Further reference Figure 3As shown, the load structure 2 includes a load cylinder 21, a dispersion disk 22, and connecting rods 23. The load cylinder 21 is installed on the top surface of the dispersion disk 22. The load cylinder 21 is used to contain the lithium battery material to be dispersed. It can be a cylindrical cylinder. The dispersion disk 22 can adopt a disc-shaped structure. Its function is to receive all the excitation force and receive the transmission range. Several connecting rods 23 are provided. One end is distributed on the bottom surface of the dispersion disk 22, and the other end is connected to the excitation structure 3. In this embodiment, four connecting rods 23 are used as an example. The use of four connecting rods 23 can ensure that the dispersion disk 22 can be stably connected to the excitation structure 3 and provide stable excitation force transmission.

[0055] Specifically, the load cylinder 21 contains the lithium battery material to be dispersed and is connected by the dispersion disk 22. The dispersion disk 22 expands the receiving range, and the excitation force is stably transmitted to the load cylinder 21 through several connecting rods 23, so that the load structure 2 can effectively disperse the internal lithium battery material under the action of the excitation force.

[0056] Furthermore, refer to Figure 3 As shown, the excitation structure 3 also includes an upper excitation platform 32, a lower excitation platform 33, a second elastic part 34, and an excitation guide part 35. The excitation source 31 is installed between the upper excitation platform 32 and the lower excitation platform 33. The bottom surface of the upper excitation platform 32 and the top surface of the lower excitation platform 33 are provided with a plurality of mounting grooves 36. One end of the second elastic part 34 is located in the mounting groove 36 of the upper excitation platform 32, and the other end is located in the mounting groove 36 of the lower excitation platform 33. Therefore, the number of second elastic parts 34 is consistent with the number of mounting grooves 36, and they correspond one-to-one. The second elastic part 34 can be a second spring. The second elastic part 34 is fixed by the mounting groove 36 to prevent the second elastic part 34 from falling out of the mounting groove 36.

[0057] The mounting slot 36 is also provided with an excitation guide port 37. The top end of the excitation guide part 35 is connected to the upper excitation platform 32, and the bottom end is inserted through the resonance structure 4 and connected to the lower excitation platform 33. The resonance structure 4 does not obstruct the movement of the excitation guide part 35. The excitation guide part 35 adopts an excitation guide rod. The function of the excitation guide part 35 is to limit the lateral displacement of the second elastic part 34, prevent the second elastic part 34 from deflecting or twisting during operation, and ensure that the second elastic part 34 is only compressed or stretched along the axial direction, thereby maintaining the stability of the excitation force transmission and expanding the resonance force.

[0058] Specifically, the excitation source 31 is installed on the upper excitation platform 32 and the lower excitation platform 33, and the excitation force generated by the excitation source 31 is transmitted by the second elastic part 34. At the same time, the excitation force is amplified and transmitted to the resonant structure 4. The excitation guide part 35 provides the anti-displacement effect of the second elastic part 34 to ensure the stability of the excitation force transmission.

[0059] Further, refer to Figure 3 and Figure 4As shown, the resonance structure 4 includes a first resonance platform 41, a resonance seat 42, a third elastic part 43, a second resonance platform 44, and a resonance guide part 45. Several resonance seats 42 are provided and distributed on the top surface of the first resonance platform 41. The resonance seat 42 can adopt a cylindrical structure. The first resonance platform 41 is installed on the top of the first elastic part 12. It is supported by the elastic force of several first elastic parts 12. When subjected to excitation force, the first layer of elastic force of the first elastic part 12 can be used to resonate and amplify the excitation force.

[0060] The third elastic part 43 is connected to the resonance seat 42 in a one-to-one correspondence, and the resonance seat 42 is provided with a resonance guide port. The third elastic part 43 can be a third spring, and the connection with the resonance seat 42 can be a fixed connection. In this embodiment, the number of resonance seats 42 is four sets. The number of third elastic parts 43 is the same as that of resonance seats 42, which can be four sets, and they are installed in a one-to-one correspondence. The function of the third elastic part 43 is to amplify the excitation force transmitted by the second elastic part 34.

[0061] The second resonance platform 44 is connected to the third elastic part 43, and the second resonance platform 44 has a mounting port 441 corresponding to the position of the resonance seat 42. The mounting port 441 provides for the installation of the third elastic part 43, so that the second resonance platform 44 can transmit the excitation force to the third elastic part 43. When the excitation source 31 is large, the second resonance platform 44 has a connecting port, so that the excitation source 31 can pass through the second resonance platform 44 without contacting the second resonance platform 44.

[0062] The resonance guide part 45 is inserted into the resonance guide port and extends through the mounting port 441 in a direction away from the first resonance stage 41. The resonance guide part 45 may be a resonance guide rod, which has a similar function to other guide rods. It is used to limit the lateral displacement of the third elastic part 43, prevent the third elastic part 43 from deflecting or twisting during operation, and ensure that the third elastic part 43 is only compressed or stretched along the axial direction, thereby maintaining the stability of the excitation force transmission and increasing the resonance intensity.

[0063] The second resonant platform 44 is also provided with several excitation ports 442. The second elastic part 34 of the excitation structure 3 is connected to the second resonant platform 44 through the excitation ports 442, so that the second elastic part can transmit the excitation force to the second resonant platform 44. The second resonant platform 44 is connected to the third elastic part 43, so the third elastic part 43 can receive the excitation force transmitted by the second resonant platform 44 to amplify the excitation force. Then, through the resonant seat 42 and the first resonant platform 41, the excitation force is transmitted to the first elastic part 12, forming an energy transfer path, thereby realizing multi-layer amplification of the excitation force to improve the dispersion of lithium battery materials.

[0064] Furthermore, the third elastic part 43 and the second elastic part 34 are both divided into two segments, with the first segment located above the second resonance platform 44 and the second segment located below the second resonance platform 44.

[0065] The top and bottom surfaces of the second resonant platform 44 are also provided with a number of excitation grooves 443. One end of the first section of the second elastic part 34 is fixedly connected to the bottom surface of the upper excitation platform 32, and the other end is fixedly connected to the excitation groove 443 on the top surface of the second resonant platform 44. One end of the second section is fixedly connected to the top surface of the lower excitation platform 33, and the other end is fixedly connected to the excitation groove 443 on the bottom surface of the second resonant platform 44. The excitation port 442 is used for the passage of the excitation guide part 35. After the second elastic part 34 is divided into two sections, it can provide the transmission of the two excitation forces, further improving the amplification and transmission efficiency of the excitation force.

[0066] When the third elastic part 43 is divided into two sections, the top and bottom surfaces of the second resonance platform 44 are also provided with several connecting grooves 444. One end of the first section is fixedly connected to the connecting groove 444 at the top of the second resonance platform 44 and extends upward. One end of the second section is fixedly connected to the connecting groove 444 at the bottom of the second resonance platform 44, and the other end is fixedly connected to the resonance seat 42 on the top surface of the first resonance platform 41. The function of dividing the third elastic part 43 into two sections is that when the excitation force transmitted by the second elastic part 34 is transmitted to the second resonance platform 44, it is transmitted to the first resonance platform 41 through the first section and the excitation force is amplified. The second section is an extension and is not connected to any fixed structure. This method allows the second section to swing or vibrate under the influence of the excitation force after the excitation force is transmitted to the second section of the third elastic part 43, thereby forming an excitation arc and thus amplifying the excitation force.

[0067] In some embodiments, reference Figure 5 As shown, the resonant structure 4 also includes a fixed rod 46 and a first threaded part 47; the fixed rod 46 is installed on the first resonant platform 41 and has an external thread on its top. The fixed rod 46 is installed in a fixed manner, so it will not be able to move along the resonant guide opening when subjected to excitation force like the resonant guide part 45. At the same time, its top can be connected to other components using the external thread.

[0068] The resonant guide part 45 has a through-hole. The outer diameter of the fixing rod 46 is smaller than the inner diameter of the through-hole, so that the resonant guide part 45 can be connected to the fixing rod 46 and move up and down along the fixing rod 46. Therefore, when the excitation force is transmitted, the fixing rod 46 will not affect the movement of the resonant guide part 45.

[0069] The third elastic part 43 has a resonance cover 48 at one end away from the first resonance platform 41, and the resonance cover 48 has a sliding opening, so that the end of the fixing rod 46 with external thread passes through the through opening and the sliding opening and extends away from the first resonance platform 41. The resonance guide part 45 can be connected to the resonance cover 48, and the resonance cover 48 can move up and down along the sliding opening.

[0070] The first threaded part 47 is screwed to the external thread of the fixing rod 46 and abuts against the resonance cover 48. The first threaded part 47 can be a block structure with a threaded hole or a nut-like structure, which can be screwed to the external thread at the top of the fixing rod 46.

[0071] Specifically, the first threaded part 47 is used to adjust the extension and retraction of the third elastic part 43, thereby adjusting the amplification of the excitation force and adapting to the resonance dispersion frequency of the lithium battery material. The first threaded part 47 continuously pushes the resonance cover 48 downward through the external thread of the fixing rod 46, thereby causing the resonance cover 48 to press down on the third elastic part 43, changing the deformation or extension and retraction of the third elastic part 43, thereby adjusting the amplification of the excitation force. The fixing rod 46 is set vertically through the mounting port 441, the through port, and the sliding port. After the excitation source 31 eliminates the horizontal excitation force, only the vertical excitation force remains. Therefore, the resonance guide part 45 and the resonance cover 48 can move along the fixing rod 46 without affecting the transmission of the excitation force.

[0072] Further reference Figure 5 and Figure 6 As shown, a pivot groove 481 is formed on one surface of the resonance cover 48. Taking the figure as an example, the pivot groove 481 is formed on the top surface of the resonance cover 48. A pivot ring 471 is provided at one end of the first threaded part 47 near the third elastic part 43. The pivot ring 471 is located in the pivot groove 481. The pivot groove 481 is a stepped groove, and the pivot ring 471 is a corresponding stepped ring structure. The function of the pivot groove 481 is to limit the pivot ring 471 and prevent the pivot ring 471 from disengaging from the pivot groove 481. The first threaded part 47 and the pivot ring 471 are fixedly connected. Therefore, when the pivot ring 471 cannot disengage from the pivot groove 481, the first threaded part 47 rotates along the external thread of the fixed rod 46 and can move vertically along the fixed rod 46. Thus, the pivot ring 471 can be used to drive the resonance cover 48 to rise and fall. The resonance cover 48 can be used to stretch and compress the third elastic part 43 to adjust the amount of expansion and contraction of the third elastic part 43.

[0073] To better showcase the structure, Figure 5 The first threaded part 47 and the resonance cover 48 are in a separated state, and the pivot ring 471 and the pivot groove 481 are also in a separated state.

[0074] Specifically, the first threaded part 47 rotates along the pivot groove 481 via the pivot ring 471. During the rotation, the first threaded part 47 moves up and down along the external thread of the fixed rod 46, and simultaneously drives the resonance cover 48 to move along the fixed rod 46 via the pivot ring 471, so as to adjust the amount of expansion and contraction of the third elastic part 43.

[0075] Furthermore, when the third elastic part 43 and the second elastic part 34 are divided into two segments, since both segments of the second elastic part 34 are connected to the second resonance platform 44, when the first threaded part 47 rotates along the external thread of the fixed rod 46, the rotation of the first threaded part 47 synchronously drives the first segment of the third elastic part 43 to extend and retract. The second resonance platform 44 is pulled or pushed synchronously down or up due to the elastic force change of the first segment of the third elastic part 43, thereby changing the extension and retraction of the two segments of the second elastic part 34 and the second segment of the third elastic part 43, so as to achieve the function of adjusting the extension and retraction of the second elastic part 34.

[0076] Further, refer to Figure 5 As shown, the top surface of the first threaded part 47 is also provided with an angle scale, and the top surface of the resonance cover 48 or the fixing rod 46 is provided with a reference scale. The figure takes the fixing rod 46 as an example. The angle scale and the reference scale are to allow the adjuster to clearly understand the rotation angle of the first threaded part 47. Since there are several third elastic parts 43, this embodiment takes four groups as an example. Therefore, it is necessary to adjust four groups of first threaded parts 47. The rotation angle or number of turns of the first threaded part 47 must be the same in order to achieve synchronous adjustment of the extension and contraction of all third elastic parts 43. Therefore, the adjuster can observe the rotation angle or number of turns and rotate all the first threaded parts 47 by the same number of turns or angle to achieve synchronous adjustment.

[0077] In some embodiments, reference Figure 7 As shown, the fixing rod 46 is slidably connected to the first resonance platform 41, that is, a fixing port is provided on the first resonance platform 41, the fixing rod 46 extends through the fixing port to the support structure 1, and the fixing rod 46 is pivotally connected to the support base 11. Specifically, a pivot hole or a pivot bearing can be provided on the base 11, and the fixing rod 46 is inserted into the pivot hole or the pivot bearing to achieve the rotation effect.

[0078] The fixing rod 46 between the first resonance platform 41 and the base 11 is also provided with a second threaded part 49, a resonance connecting plate 491, and a fourth elastic part 411. The second threaded part 49 is screwed to the fixing rod 46. The second threaded part 49 has the same structure as the first threaded part 47. Both can adopt a block structure with threaded holes or a nut-shaped structure, and both are provided with a pivot ring 471. The resonance connecting plate 491 has a sliding port and a pivot groove 481 that are the same as those of the resonance cover 48. The sliding port allows the fixing rod 46 to pass through. The second threaded part 49 is pivotally connected to the pivot groove 481 through the pivot ring 471. The fourth elastic part 411 is a fourth spring. One end is connected to the bottom surface of the first resonance platform 41, and the other end is connected to the resonance connecting plate 491.

[0079] The center point of the fixed rod 46 in the length direction is used as the dividing line, and the thread direction of the external threads on both sides of the dividing line is opposite.

[0080] As the fixed rod 46 rotates, the first threaded part 47 and the second threaded part 49 are subjected to opposite driving forces, and they move relative to each other or in opposite directions, so that they unfold synchronously and extend or contract the second elastic part 34, the third elastic part 43 and the fourth elastic part 411, thereby further realizing the adjustment of the expansion and contraction of the elastic parts. Although the fixed rod 46 is pivotally connected to the base 11, the fourth elastic part 411 can cooperate with the first elastic part 12, and the first resonance platform 41 can slide to connect with the fixed rod 46, so that the support effect provided by the fixed rod 46 is not affected and the excitation effect is improved.

[0081] Further reference Figure 8 As shown, each group of third elastic parts 43 is provided with a fixed rod 46. Therefore, several fixed rods 46 are distributed on the base 11 with the load structure 2 as the axis. A linkage gear 492 is provided on the fixed rod 46. A linkage gear ring 493 meshes with all linkage gears 492. A single linkage gear ring 493 meshes with all linkage gears 492, so that by simply rotating the linkage gear ring 493 or any linkage gear 492, all fixed rods 46 can be rotated to achieve synchronous adjustment of the extension and contraction of the second elastic part 34, the third elastic part 43 and the fourth elastic part 411, so as to adjust the excitation effect.

[0082] The linkage gear ring 493 can be an external gear ring or an internal gear ring, depending on the requirements. In this application, an external gear ring is used as an example, where the tooth-like structure is located on the outer wall of the gear ring. The base 11 is also provided with an annular slide rail 111, and the linkage gear ring 493 is slidably connected to the annular slide rail 111, which provides support and pivoting for the linkage gear ring 493.

[0083] Among them, reference Figure 8 As shown, an adjustment motor 112 (the dotted line in the figure) can be installed at any of the linkage gears 492 or linkage ring gears 493. The drive end of the adjustment motor 112 can be connected to the adjustment gear 113. The adjustment gear 113 meshes with the linkage gear 492 or linkage ring gear 493. The adjustment motor 112 can be used to quickly adjust the number of rotations of the linkage gear 492 and the fixed rod 46, so as to achieve synchronous and rapid adjustment of the extension and retraction of all the second elastic parts 34, the third elastic parts 43 and the fourth elastic parts 411.

[0084] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
