Description

Technical Field

[0001] This application relates to the field of vibration reduction technology, and more particularly to a coil assembly, a vibration damper, and a vehicle. Background Technology

[0002] In related technologies, vehicles are equipped with shock absorbers in the wheel area to reduce vehicle bumps during driving. The working principle of a shock absorber is that when the vehicle body vibrates, the piston inside the shock absorber moves up and down. The oil in the shock absorber's chambers repeatedly flows from one chamber to another through different orifices, creating a damping force. This converts the energy of the vehicle's vibration into heat energy in the oil, which is absorbed by the shock absorber and dissipated into the atmosphere. Common shock absorbers typically include a coil assembly, which consists of a bracket, a coil wound on the bracket, and a magnetic conductor at one end of the coil. Due to the influence of the structure and shape of the magnetic conductor, the magnetic performance of the coil assembly can be unstable. Utility Model Content

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0051] According to a first aspect of this application, a coil assembly 10 is provided; see [link to relevant documentation]. Figures 1 to 6 , Figure 1 This is a partial cross-sectional view of an application scenario of a coil assembly provided in an embodiment of this application. Figure 2 yes Figure 1 A three-dimensional structural diagram of the provided coil assembly. Figure 3 yes Figure 2 Top view of the provided coil assembly. Figure 4 yes Figure 2 A three-dimensional structural diagram of the magnetic conductive component of the provided coil assembly. Figure 5 yes Figure 2 A three-dimensional structural diagram of the support frame for the provided coil assembly. Figure 6 yes Figure 2A cross-sectional view of the provided coil assembly. The coil assembly 10 includes: a support 20; a coil 30 wound around a winding axis on the support 20; and a plurality of magnetic conductors 40 disposed at one end of the support 20 along the winding axis.

[0052] In this embodiment, multiple magnetic conductive elements 40 are provided at one end of the support 20 along the winding axis. Since the multiple magnetic conductive elements 40 have various arrangement forms, they can be flexibly arranged according to actual needs. For example, the multiple magnetic conductive elements 40 can be evenly distributed circumferentially on the support 20 so that the magnetic lines of force generated after the coil 30 is energized can be evenly distributed. Alternatively, the multiple magnetic conductive elements 40 can be divided into multiple parts to form a symmetrical distribution, which can also adjust the distribution of magnetic lines of force around the coil assembly 10. Therefore, the coil assembly 10 of this application has multiple magnetic conductive elements 40, and the distribution of magnetic lines of force around the coil assembly 10 can be flexibly adjusted through the various arrangement forms of the multiple magnetic conductive elements 40 to adjust the magnetic performance of the coil assembly 10.

[0053] Please continue reading. Figures 2 to 4 In some embodiments of this application, the plurality of magnetic conductors 40 are rotationally symmetrical about the center of the winding axis.

[0054] When the coil assembly 10 is working, the magnetic field lines generated by the energized coil 30 will pass through the magnetic conductor 40, forming a magnetic field around the coil assembly 10. In this embodiment, by making the multiple magnetic conductors 40 rotationally symmetrical about the axis of rotation, it helps to make the magnetic field lines around the coil assembly 10 more uniformly distributed, thereby improving the magnetic performance of the coil assembly 10.

[0055] In some embodiments of this application, the plurality of magnetic conductive elements 40 include a first magnetic conductive element and a second magnetic conductive element, and the bracket 20 is provided with a first positioning structure 211, with the first magnetic conductive element and the second magnetic conductive element respectively disposed on both sides of the first positioning structure 211.

[0056] By adopting this scheme, the positions of the first magnetic conductor and the second magnetic conductor can be defined by the first positioning structure 211, reducing the possibility of displacement of the first magnetic conductor and the second magnetic conductor on the bracket 20, fixing the first magnetic conductor and the second magnetic conductor on the bracket 20, and improving the reliability of the coil assembly 10.

[0057] In some embodiments of this application, multiple magnetic conductive elements 40 are evenly distributed on both sides of the first positioning structure 211. This ensures that the number of magnetic conductive elements 40 on both sides of the first positioning structure 211 is the same, which helps to achieve a uniform distribution of magnetic field lines.

[0058] In some embodiments of this application, at least two magnetic conductive elements 40 are respectively provided on both sides of the first positioning structure 211, and any two adjacent magnetic conductive elements 40 provided on the same side of the first positioning structure 211 abut against each other.

[0059] This design allows the magnetically conductive elements 40 to support each other, reducing the possibility of displacement caused by gaps between them and improving the reliability of the coil assembly 10. Furthermore, the contact between multiple magnetically conductive elements 40 also helps to form a closed magnetic circuit.

[0060] In some embodiments of this application, among the plurality of magnetic conductive elements 40, the magnetic conductive element 40 adjacent to the first positioning structure 211 abuts against the first positioning structure 211. In this way, the first positioning structure 211 can be used to prevent the magnetic conductive elements 40 disposed on both sides of the first positioning structure 211 from moving towards each other, that is, to reduce the possibility of displacement of the magnetic conductive elements 40 on the bracket 20, which helps to improve the reliability of the coil assembly 10.

[0061] Please see Figures 2 to 7 , Figure 7 yes Figure 2 Another cross-sectional view of the provided coil assembly shows the connector. In some embodiments of this application, the bracket 20 has a first connecting surface 21, a plurality of magnetic conductive elements 40 are disposed on the first connecting surface 21, the two ends of the first positioning structure 211 extend to the edge of the first connecting surface 21, and a wire groove 60 is provided at the connection between the first positioning structure 211 and the edge of the first connecting surface 21, and the terminal of the coil 30 is disposed in the wire groove 60. In this way, on the one hand, the wire groove 60 can be used to limit the position of the terminal of the coil 30, reducing the possibility of displacement of the terminal of the coil 30 during the operation of the coil assembly 10. On the other hand, it can also prevent the terminal of the coil 30 from protruding from the outer surface of the bracket 20, reducing the probability of damage to the terminal of the coil 30 and improving the reliability of the coil assembly 10.

[0062] In some embodiments of this application, the magnetic conductive elements 40 disposed on both sides of the first positioning structure 211 are symmetrically arranged about the first positioning structure 211. This helps to make the magnetic field lines around the coil assembly 10 more uniformly distributed, thereby improving the magnetic performance of the coil assembly 10.

[0063] In some embodiments of this application, the first positioning structure 211 extends along a straight line, and the magnetic conductive elements 40 disposed on both sides of the first positioning structure 211 are symmetrical about the straight line.

[0064] In some embodiments of this application, the coil assembly 10 further includes a conductive element 50 disposed within the first positioning structure 211, with one end connected to the coil 30.

[0065] By adopting this scheme, the first positioning structure 211 can be used to restrict the movement of the conductive element 50, reduce the possibility of displacement of the conductive element 50, thereby improving the connection stability between the conductive element 50 and the coil 30, and thus improving the reliability of the coil assembly 10.

[0066] Please see Figure 7 In some embodiments of this application, the conductive element 50 has a first connection end 51 and a body 52 connected to each other. The first connection end 51 is connected to the coil 30, and the body 52 is at least partially disposed within the first positioning structure 211.

[0067] In this embodiment, the body 52 of the conductive element 50 is disposed within the first positioning structure 211. The first positioning structure 211 can protect and limit the body 52, thereby improving the connection stability between the coil 30 and the conductive element 50 and helping to improve the reliability of the coil assembly 10. At the same time, placing the first connection end 51 connected to the coil 30 outside the first positioning structure 211 facilitates the connection between the coil 30 and the conductive element 50, which helps to improve assembly efficiency.

[0068] Please continue reading. Figure 7 In some embodiments of this application, the body 52 is at least partially embedded within the first positioning structure 211. This ensures that the conductive element 50 is fixed by the first positioning structure 211, while the connection between the conductive element 50 and the coil 30 is not affected by the first positioning structure 211.

[0069] In some embodiments of this application, when manufacturing the bracket 20, the manufactured conductive element 50 is fixed in a mold, and insulating materials such as plastic are injected into the mold to obtain the bracket 20 with the conductive element 50 by injection molding. This eliminates the need to create wiring grooves on the bracket 20 during manufacturing and eliminates the need for wiring when assembling the coil assembly 10, thus simplifying the manufacturing process and reducing production costs. Furthermore, the conductive element 50 and the bracket 20 are tightly connected using this method, improving the connection stability between the conductive element 50 and the coil 30, thereby enhancing the reliability of the coil assembly 10.

[0070] Please see Figures 2 to 7 In some embodiments of this application, the conductive element 50 also has a second connection end 53 connected to the body 52, and the surface of the second positioning structure 212 away from the coil 30 is provided with a boss 22, and the second connection end 53 is exposed from the boss 22.

[0071] This approach ensures the ease of connecting the second connection end 53 of the conductive component 50 to the circuit, while also using the boss 22 to keep the second connection end 53 of the conductive component 50 away from the magnetic component 40, reducing interference to the magnetic component 40 and helping to improve the reliability of the coil assembly 10.

[0072] Please continue reading. Figures 2 to 7 In some embodiments of this application, the coil assembly 10 has two conductive elements 50, which are symmetrically arranged along the length direction of the first positioning structure 211.

[0073] In this embodiment, two conductive elements 50 are provided, allowing different circuits to be connected using the two conductive elements 50, making it suitable for more application scenarios and helping to expand the applicability of the coil assembly 10 provided in this application. At the same time, the symmetrical arrangement of the two conductive elements 50 can make the magnetic field generated by the coil 30 more uniformly distributed, which helps to improve the consistency of the damping force of the shock absorber.

[0074] Please continue reading. Figures 2 to 7 In some embodiments of this application, the coil assembly 10 further includes a separator 221 disposed on the boss 22, which separates the second connection ends 53 of the two conductive elements 50. This prevents the second connection ends 53 of the two conductive elements 50 from becoming conductive due to contact, ensuring the normal operation of the circuit connected to the two conductive elements 50, and helping to reduce the likelihood of roller failure in the coil assembly 10, thereby improving the reliability of the coil assembly 10.

[0075] Please see Figure 7 In some embodiments of this application, the coil assembly 10 further includes a connector 70, which is connected to the bracket 20 and a plurality of magnetic conductive elements 40, and the connector 70 conducts the plurality of magnetic conductive elements 40.

[0076] In this embodiment, by providing a connector 70 and using the connector 70 to make the two magnetic conductors 40 conductive, an efficient closed magnetic circuit is formed along the magnetic conductors 40—connector 70—magnetic conductors 40. Therefore, using the connector 70 to make the two magnetic conductors 40 conductive can enhance the strength and stability of the magnetic field and improve the magnetic performance of the coil assembly 10.

[0077] Please continue reading. Figure 7 In some embodiments of this application, the bracket 20 has a mounting groove 23 on the surface opposite to the first connecting surface 21. The bottom of the mounting groove 23 extends to the first connecting surface 21, and a second connecting hole 213 and a third connecting hole 214 are formed on the first connecting surface 21. The second connecting hole 213 and the third connecting hole 214 are respectively located on both sides of the first positioning structure 211. The connector 70 is disposed in the mounting groove 23, and the connector 70 abuts against the magnetic conductor 40 exposed from the second connecting hole 213 and the third connecting hole 214 to conduct multiple magnetic conductors 40.

[0078] In this way, the magnetic conductor 40 and the connector 70 can be connected conveniently, and at the same time, the outer peripheral surface of the coil assembly 10 is free of protruding structures, which improves the reliability of the coil assembly 10.

[0079] In some embodiments of this application, the bracket 20 has a first connecting surface 21, and a plurality of magnetic conductive elements 40 are disposed on the first connecting surface 21. The bracket 20 also has a second positioning structure 212 disposed on the first connecting surface 21. In this way, the position of the magnetic conductive elements 40 can be defined by the second positioning structure 212, reducing the probability of movement of the magnetic conductive elements 40 and helping to improve the reliability of the coil assembly 10.

[0080] In some embodiments of this application, the second positioning structure 212 is a positioning post, and the magnetic conductive element 40 has a first connecting hole 41, and the positioning post is inserted into the first connecting hole 41 for positioning.

[0081] In this embodiment, a positioning post and a first connecting hole 41 are respectively provided on the first connecting surface 21 and the magnetic conductive element 40, so that the magnetic conductive element 40 can be fixed by inserting the positioning post and the first connecting hole 41 to avoid displacement of the magnetic conductive element 40, which helps to improve the reliability of the coil assembly 10 and thus improve the magnetic performance of the coil assembly 10.

[0082] In some embodiments of this application, the second positioning structure 212 is a positioning groove, and multiple magnetic conductive elements 40 are embedded in the positioning groove.

[0083] In some embodiments of this application, the projection of the first connecting hole 41 onto the first connecting surface 21 is circular.

[0084] In some embodiments of this application, by setting a first positioning structure 211, and having the adjacent magnetic conductive element 40 abut against the first positioning structure 211, the magnetic conductive elements 40 on both sides of the first positioning structure 211 are prevented from moving towards each other. Based on this, a second positioning structure 212 can be used to further limit the position of the magnetic conductive element 40, preventing it from moving in other directions. In some embodiments of this application, the second positioning structure 212 is disposed on the first connecting surface 21. When the second positioning structure 212 is a positioning post, the magnetic conductive element 40 has a first connecting hole 41, which is inserted into and positioned with the positioning post, thus fixing the magnetic conductive element 40 to the bracket 20.

[0085] Please see Figure 6 In some embodiments of this application, the surfaces of multiple magnetic conductors 40 that are away from the first connecting surface 21 are located in the same plane.

[0086] This approach facilitates the balancing of weight distribution on both sides of the first plane of the coil assembly 10, thereby improving the structural stability and reliability of the coil assembly 10.

[0087] According to a second aspect of this application, a vibration damper is provided, including the coil assembly 10 as described above. This vibration damper possesses all the beneficial effects of the coil assembly 10 described above, which will not be elaborated further herein.

[0088] According to a third aspect of this application, a vehicle is provided, including the shock absorber described above. The vehicle possesses all the beneficial effects of the described shock absorber, which will not be elaborated further herein.
