[0045] The embodiments of this utility model will now be described in detail. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0047] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] In related technologies, the vibration component includes a frame and two hubs. The two hubs are symmetrically arranged on opposite sides of the frame. The frame assembly for mounting magnetic components is formed by riveting the frame and the two hubs. This makes the assembly process of the frame assembly relatively complex, and the frame and hubs may fall apart under high-frequency vibration conditions, thus affecting the working reliability of the actuator.

[0050] This application provides an actuator, which will be described in detail below with reference to the accompanying drawings.

[0051] Reference Figures 1 to 3 The diagram shows a schematic representation of the actuator provided in an embodiment of this application. Figures 4 to 6 The diagram shows a structural schematic of the support member and skeleton provided in an embodiment of this application. (Refer to...) Figure 7 The figure shows a schematic diagram of the actuator provided in an embodiment of this application. It should be noted that the first direction X in the figure refers to the axial direction of the actuator.

[0052] like Figures 1 to 3 As shown, this application provides an actuator, including: a housing 1 and a vibration assembly; the housing 1 is provided with a first mounting cavity 11; the vibration assembly is disposed in the first mounting cavity 11, and the vibration assembly includes a support member 2, a frame 3 and a magnetic member 4, the support member 2 is movably connected to the first mounting cavity 11, the frame 3 is connected to the support member 2, and the magnetic member 4 is disposed on the frame 3; wherein, the support member 2 and the frame 3 are integrally formed structures.

[0053] In this embodiment, since the support member 2 and the frame 3, which form the vibration component skeleton assembly, are integrally molded structures, meaning that the support member 2 and the frame 3 are manufactured as a single unit, on the one hand, the support member 2 and the frame 3 do not require additional assembly, thus simplifying the subsequent assembly of the actuator. On the other hand, as a single unit, the support member 2 and the frame 3 will not fall apart even under high-frequency vibration conditions, thereby improving the operational reliability of the actuator.

[0054] In some optional embodiments of this application, the support 2 is a plastic support, and the frame 3 is a metal frame. The plastic support is relatively lightweight, reducing the weight of the frame assembly and facilitating actuator assembly and lightweight design. The metal frame has good magnetic permeability and rigidity, not only conducting the magnetic field but also better supporting the magnetic component 4 and withstanding vibrations generated during actuator operation, thus improving the actuator's reliability.

[0055] It should be noted that the plastic support component and the metal frame can be integrally molded using injection molding. Specifically, the metal frame is placed as an insert in the mold, and plastic material is injected into the mold. After cooling and solidification, a one-piece frame assembly is obtained. In other words, injection molding allows for better control over the dimensions of the frame assembly, resulting in a more robust connection between the support component 2 and the frame 3.

[0056] In some alternative embodiments of this application, such as Figures 4 to 6 As shown, the actuator also includes an actuating rod 5, which is used to connect to the device to be damped; the support member 2 includes a first support ring 21 and a second support ring 22 spaced apart from the inside to the outside, the first support ring 21 is connected to the actuating rod 5, and the second support ring 22 is connected to the frame 3.

[0057] In this embodiment, the actuating rod 5, connected to the support member 2 and the device to be damped, allows the vibration generated by the vibration assembly to cancel out the vibration of the device itself, thus achieving active vibration damping. The first support ring 21 and the second support ring 22, connected to the actuating rod 5 via the inner support ring 21 and to the frame 3 via the outer support ring 22, ensure reliable connection between the support member 2, the actuating rod 5, and the frame 3, facilitating effective force transmission. It should be noted that, to improve the working stability of the actuator, the actuating rod 5, the first support ring 21, the second support ring 22, and the frame 3 are typically coaxially arranged.

[0058] In some optional embodiments of this application, the second support ring 22 is provided with a first limiting part 221; the frame 3 is provided with a second limiting part 31 at a position corresponding to the second support ring 22, and the second limiting part 31 is engaged with the first limiting part 221. Specifically, the second support ring 22 has a first peripheral wall near the frame 3, and the first limiting part 221 is disposed on the first peripheral wall; the frame 3 has a second peripheral wall near the second support ring 22, and the second limiting part 31 is disposed on the second peripheral wall and is engaged with the first limiting part 221.

[0059] Furthermore, the first limiting part 221 is either a limiting protrusion or a limiting groove, and the second limiting part 31 is either a limiting protrusion or a limiting groove, with the limiting protrusion and the limiting groove engaging in a locking action.

[0060] In this embodiment, since the second support ring 22 and the frame 3 are respectively provided with limiting grooves and limiting protrusions at corresponding positions, a reliable connection between the second support ring 22 and the frame 3 can be achieved through the engagement of the limiting grooves and limiting protrusions.

[0061] It should be noted that the number of limiting protrusions and limiting grooves is not limited in the embodiments of this application, and those skilled in the art can adjust it according to actual needs. It is understood that when multiple limiting protrusions and limiting grooves are provided, the connection between the second support ring 22 and the frame 3 can be made more secure. Furthermore, the accompanying drawings of this application only show the case where the second support ring 22 is provided with a limiting groove, and the corresponding position of the frame 3 is provided with a limiting protrusion. In practical applications, those skilled in the art can also provide a limiting protrusion on the second support ring 22 and a limiting groove on the corresponding position of the frame 3, or simultaneously provide either a limiting protrusion or a limiting groove on the first support ring 21 and simultaneously provide both a limiting groove and a limiting protrusion on the corresponding position of the frame 3; this is not limited here.

[0062] In one embodiment, a limiting groove is provided, which extends circumferentially along the second support ring 22, and a limiting protrusion is provided, which extends circumferentially along the skeleton 3. By engaging the limiting groove and the limiting protrusion, a reliable connection between the first support ring 21 and the skeleton 3 can be achieved.

[0063] In another embodiment, multiple limiting grooves are provided, spaced apart, thereby forming an uneven texture on the surface of the skeleton 3; correspondingly, multiple limiting protrusions are provided, spaced apart, thereby forming a matching uneven texture on the surface of the second support ring 22. Through the one-to-one cooperation of the limiting grooves and limiting protrusions, the second support ring 22 can be further improved.

[0064] Reliability of the connection between ring 22 and skeleton 3.

[0065] In some optional embodiments of this application, the actuating rod 5 passes through and is fixedly connected to the first support ring 21. Specifically, the first support ring 21 has a first through hole, and the actuating rod 5 passes through the first through hole. Further, as... Figure 7 As shown, the actuating rod 5 includes a rod body 51 and two locking parts 52, which are spaced apart in the axial direction of the rod body 51; the first support ring 21 is locked between the two locking parts 52.

[0066] In this embodiment, the connection method of snapping the first support ring 21 between the two snap-fit ​​portions 52 of the actuating rod 5 is simple and reliable. It not only achieves a reliable connection between the first support ring 21 and the actuating rod 5, but also simplifies the structure of the first support member 2 and the actuating rod 5, reducing the processing difficulty of the actuator and improving the ease of assembly and disassembly. In one embodiment, the snap-fit ​​portion 52 can be an annular protrusion formed around the rod body 51, which further simplifies the structure of the actuating rod 5.

[0067] In some optional embodiments of this application, the actuator further includes two elastic members 6, one elastic member 6 being engaged between the first support ring 21 and a engaging portion 52 and connected to the housing 1. Specifically, as Figure 3 , Figure 4 as well as Figure 7 As shown, the latching part 52 includes a first latching part located at the top and a second latching part located at the bottom. The elastic member 6 includes a first elastic member located at the top and a second elastic member located at the bottom. The first elastic member latches between the first support ring 21 and the first latching part and is connected to the housing 1. The second elastic member latches between the first support ring 21 and the second latching part and is connected to the housing 1. In this way, on the one hand, the connection between the support member 2 and the housing 1 can be realized; on the other hand, the elastic member 6 can provide support and limit the support member 2, the frame 3, the permanent magnet, etc.

[0068] It should be noted that the elastic element 6 refers to a structural component that can undergo elastic deformation under external force. In one embodiment, the elastic element 6 can be a spring sheet. The spring sheet has a second through hole at the corresponding position of the actuating rod 5. The actuating rod 5 passes through the second through hole, and the spring sheet located at the edge of the second through hole is engaged between the engaging part 52 of the actuating rod 5 and the end of the first support ring 21, thereby realizing the connection between the spring sheet and the support element 2. The housing 1 includes an end cap 14, and the edge of the spring sheet is pressed together with the end cap 14, thereby realizing the connection between the spring sheet and the housing 1. In addition, the surface of the spring sheet can be processed with various shapes of hollow structures to adjust the required stiffness and ensure that the radial alignment can still be guaranteed when the skeleton assembly moves axially (i.e., along the first direction X).

[0069] In some optional embodiments of this application, the support member 2 further includes a connecting rib 23, which is disposed between the first support ring 21 and the second support ring 22 and connected to the first support ring 21 and the second support ring 22. The connecting rib 23 may be a plate-like structure extending radially along the first support ring 21.

[0070] In this embodiment of the application, by providing a connecting rib 23 between the first support ring 21 and the second support ring 22, a reliable connection between the first support ring 21 and the second support ring 22 can be achieved, so that the force can be reliably transmitted between the first support ring 21 and the second support ring 22.

[0071] It should be noted that the number of connecting ribs 23 is not limited in the embodiments of this application, and those skilled in the art can adjust it according to actual needs. In one embodiment, multiple connecting ribs 23 are provided, and the multiple connecting ribs 23 are arranged at intervals along the circumference of the first support ring 21. In this way, on the one hand, the force transmission path can be optimized, the reliability of force transmission can be improved, and the active vibration reduction effect of the actuator can be improved. On the other hand, the hollow area formed between two adjacent connecting ribs 23 can not only reduce the weight of the support member 2, further realizing the lightweight of the actuator, but also assist in heat dissipation, which is conducive to improving the working reliability of the actuator.

[0072] In some optional embodiments of this application, a mounting groove 32 is provided on the side of the skeleton 3 facing away from the second support ring 22; the magnetic component 4 is disposed in the mounting groove 32. Specifically, the mounting groove 32 extends circumferentially along the skeleton 3, and the magnetic component 4 includes a plurality of permanent magnets, which are sequentially disposed in the mounting groove 32 along the circumferential direction of the skeleton 3.

[0073] In this embodiment, a mounting groove 32 is provided on the frame 3, and the permanent magnet constituting the magnetic component 4 is placed in the mounting groove 32. This allows the permanent magnet to be more securely fixed to the frame 3, preventing the permanent magnet from falling off during the movement of the frame 3 with the support component 2.

[0074] It should be noted that the embodiments of this application do not limit the number of mounting slots 32 and magnetic components 4, and those skilled in the art can adjust them according to actual needs. In one embodiment, two mounting slots 32 and two magnetic components 4 are provided, with the two mounting slots 32 spaced apart along the first direction X, and one magnetic component 4 disposed within one mounting slot 32. It can be understood that when the mounting slot 32 is annular, in order to better fit the magnetic component 4 with the mounting slot 32, the multiple permanent magnets constituting the magnetic component 4 can be tile-shaped, so that the magnetic component 4 as a whole can better fit the slot wall of the mounting slot 32, making the magnetic circuit structure more compact, thereby improving the effective magnetic area and magnetic energy utilization rate. Furthermore, the permanent magnets can be fixed to the slot wall of the mounting slot 32 by adhesive bonding.

[0075] In some optional embodiments of this application, the actuator further includes a coil assembly 7 connected to the housing 1 and corresponding to the position of the magnetic element 4. The coil assembly 7 is used to generate a magnetic field acting on the magnetic element 4 to drive the support member 2 to move relative to the housing 1. It is understood that the coil assembly 7 and the magnetic element 4 are arranged radially spaced apart in the actuator to form a suitable air gap between them.

[0076] In this embodiment, a coil assembly 7 is provided at the corresponding position of the magnetic component 4. The coil assembly 7 can generate a magnetic field acting on the magnetic component 4, thereby driving the support component 2 to move relative to the housing 1, thus achieving active vibration reduction. Specifically, when the coil assembly 7 is not energized, the magnetic component 4 establishes a constant magnetic field at the air gap, thereby generating a preload force. When the coil assembly 7 is energized, an alternating magnetic field is generated at the air gap, thereby changing the force on the magnetic component 4. This is equivalent to superimposing an alternating control force on the preload force. This control force can drive the magnetic component 4, the frame 3, the support component 2, the spring sheet, and the actuating rod 5 to move or deform along the first direction X. That is, the actuating rod 5 can move back and forth along the first direction X, thereby acting on the device to be vibration-damped, canceling the vibration from the device to be vibration-damped, and achieving the purpose of suppressing or eliminating vibration.

[0077] In some optional embodiments of this application, the actuator's axial direction is a first direction X. The housing 1 includes a sleeve 13 and two end caps 14. The sleeve 13 extends along the first direction X. The two end caps 14 are disposed opposite each other along the first direction X and located inside the sleeve 13. The side of the two end caps 14 away from the sleeve 13 together defines a first mounting cavity 11. The side of the two end caps 14 near the sleeve 13 and together with the sleeve 13 form a second mounting cavity 12. The coil assembly 7 is disposed in the second mounting cavity 12. Specifically, the end caps 14 include a first cover plate 141 and a second cover plate 142 connected to each other. Both the first cover plate 141 and the second cover plate 142 are annular. The first cover plate 141 extends radially along the actuator, and the second cover plate 142 extends axially along the actuator. An elastic member 6 is connected to the side of the first cover plate 141 away from the second receiving cavity.

[0078] In this embodiment, since the sleeve 13 and two end caps 14 are provided, after the sleeve 13 and the two end caps 14 are assembled, a relatively independent first mounting cavity 11 and a second mounting cavity 12 can be formed, and the second mounting cavity 12 is arranged around the first mounting cavity 11. In this way, it is not only convenient to install and fix the vibration assembly and the coil assembly 7, but also to make the coil assembly 7 correspond to the magnetic element 4 arranged on the periphery of the frame 3, so that the magnetic field generated by the coil assembly 7 can reliably act on the magnetic element 4, thereby realizing the movement of the vibration assembly.

[0079] In some optional embodiments of this application, the end cap 14 includes a first cover plate 141 perpendicular to the first direction X, and at least one of the first cover plate 141 and / or the coil assembly 7 is provided with a limiting groove 721; the actuator further includes a limiting member 8, which is disposed within the limiting groove 721 and abuts against the first cover plate 141 and the coil assembly 7 to limit the coil assembly 7. In this way, the coil assembly 7 can be limited axially to reliably fix the coil assembly 7 within the second mounting cavity 12.

[0080] In some optional embodiments of this application, the coil assembly 7 includes a coil body 71 and a coil housing 72 disposed outside the coil body 71, wherein the coil housing 72 and the coil body 71 are integrally formed. Specifically, the coil body 71 is placed in a mold as an insert, and the integral coil assembly 7 is obtained by injecting adhesive into the mold and cooling it. This not only improves the overall structural strength of the coil assembly 7, but also protects the coil body 71.

[0081] Furthermore, the coil assembly 7 also includes a wiring port 9 electrically connected to the coil body 71. The wiring port 9 is used to electrically connect to an external power supply device to supply power to the coil body 71 and control the coil body 71 to generate a magnetic field that drives the oscillator assembly to move. In one embodiment, the wiring port 9, the coil body 71, and the coil housing 72 are integrally formed.

[0082] In summary, the actuator provided in this application has at least the following advantages:

[0083] In this embodiment, the support member and the frame, which form the vibration component skeleton assembly, are integrally molded structures, meaning they are manufactured as a single unit. This simplifies the subsequent assembly of the actuator, as the support member and frame do not require additional assembly. Furthermore, the integral support member and frame will not disintegrate even under high-frequency vibration conditions, thus improving the reliability of the actuator.

[0084] This application also provides a suspension system, including a device to be damped and an actuator as described in any of the above embodiments, wherein the vibration component is connected to the device to be damped. The device to be damped refers to a device that requires vibration damping, including but not limited to an engine. By connecting the vibration component of the actuator to the device to be damped, the vibration generated by the vibration component can cancel out the vibration from the device to be damped, thereby achieving vibration reduction and noise reduction, which is beneficial for further improving vehicle comfort.
