[0027] Various aspects and features of the present invention are described herein with reference to the accompanying drawings.

[0028] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of the embodiments. Other modifications within the scope and spirit of the present utility model will occur to those skilled in the art.

[0029] The accompanying drawings, which are included in and constitute a part of the specification, illustrate embodiments of the present invention and, together with the general description of the present invention given above and the detailed description of the embodiments given below, are used to explain the principles of the present invention.

[0030] These and other characteristics of the invention will become apparent from the following description of a preferred form of embodiment given as a non-limiting example, with reference to the accompanying drawings.

[0031] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present invention that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0032] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0033] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0034] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", all of which may refer to one or more of the same or different embodiments according to the present invention.

[0035] Figures 1 to 6 FIG. 1 shows a schematic diagram of the structure of the suspension structure provided by the embodiment of the utility model. Figures 1 to 6 As shown, the first embodiment of the utility model provides a suspension structure, including a base 1, in which an inertial channel 2, an electromagnetic valve core 3 and a magnetic slider 4 are provided. The electromagnetic valve core 3 is fixedly installed in the base 1 and is electrically or signal-connected to a valve core controller (not shown in the figure). The magnetic slider 4 is movably installed in the inertial channel 2 and arranged corresponding to the electromagnetic valve core 3.

[0036] Specifically, the base 1 is a disc-shaped or bowl-shaped structure, and the inertial channel 2 can be formed by directly slotting the base 1. The magnetic slider 4 is movably installed in the position corresponding to the electromagnetic valve core 3 in the inertial channel 2. After the electromagnetic valve core 3 is energized, the "like repels like and opposites attract" characteristics of the magnetic slider 4 can be used to make the electromagnetic valve core 3 and the magnetic slider 4 interact with each other, drive the magnetic slider 4 to slide or rotate in the inertial channel 2, adjust the flow channel section of the inertial channel 2, and then adjust the flow rate of the damping fluid flowing through the inertial channel 2 to meet the vibration requirements of the whole vehicle. At the same time, the suspension structure eliminates the decoupling diaphragm, which can avoid the problem of abnormal slapping noise caused by the vibration of the decoupling diaphragm due to the increase in the damping angle.

[0037] The valve core controller can be connected to the vehicle's ECU (Electronic Control Unit). The ECU monitors the movement stroke of the vehicle shock absorber, the ground information in front of the vehicle, the vehicle speed and other vehicle driving related information in real time, analyzes and determines the working conditions of the vehicle to be driven, and then sends a control command to the valve core controller to start adjusting the suspension damping stiffness through the magnetic slider 4 to meet the vehicle vibration requirements under different driving conditions.

[0038] When the vehicle is about to perform low-frequency and large-amplitude operation, the solenoid valve core 3 and the magnetic slider 4 generate a repulsive force, and the solenoid valve core 3 controls the rotation of the magnetic slider 4. The cross-section of the channel in the inertial channel 2 (the flow channel cross-section) changes with the rotation of the magnetic slider 4, and the flow rate of the damping fluid changes accordingly, thereby adjusting the damping peak value to meet the vibration requirements of the entire vehicle.

[0039] When the vehicle is about to perform high-frequency and small-amplitude operation, the solenoid valve core 3 and the magnetic slider 4 generate an attractive force, and the solenoid valve core 3 controls the magnetic slider 4 to rotate close to the solenoid valve core 3, thereby increasing the flow cross-section of the inertial channel 2. While meeting the vibration requirements of the entire vehicle, the suspension damping stiffness can be effectively adjusted to avoid the slow flow rate of the damping fluid during high-frequency and small-amplitude excitation, thereby preventing the "high-frequency hardening" phenomenon from occurring. That is, the suspension structure has good high-frequency vibration isolation performance.

[0040] In addition, the solenoid valve core 3 and the magnetic slider 4 of the suspension structure cooperate conveniently and quickly, and can achieve faster attenuation of the powertrain and road excitation, providing users with a more comfortable driving experience.

[0041] The magnetic slider 4 is preferably a permanent magnet slider with good magnetic properties to ensure reliable operation of the suspension structure.

[0042] In some embodiments, a first mounting groove 11 for mounting the electromagnetic valve core 3 is provided at the center of the base 1 , an annular inertia channel 2 is provided on the periphery of the first mounting groove 11 , and a second mounting groove 21 for mounting the magnetic slider 4 is provided in the inertia channel 2 .

[0043] That is, the inertial channel 2 is an annular groove arranged around the first mounting groove 11, and the solenoid valve core 3 is fixed in the first mounting groove 11, so that the distance between the solenoid valve core 3 and the magnetic slider 4 in the inertial channel 2 meets certain requirements, ensuring the convenience of interaction between the two; the magnetic slider 4 moves (for example, slides or rotates) in the second mounting groove 21, and the second mounting groove 21 can limit the magnetic slider 4 to prevent the magnetic slider 4 from moving arbitrarily and causing blockage of the inertial channel 2, etc.

[0044] In some embodiments, an annular protrusion 12 with a certain thickness is provided in the base 1, a first mounting groove 11 is formed on the radial inner side of the annular protrusion 12, and an inertial channel 2 is formed between the radial outer side of the annular protrusion 12 and the outer wall of the base 1. The structure is simple and reasonable, and processing and forming are convenient.

[0045] In some embodiments, the second mounting groove 21 includes an arc-shaped groove 211 recessed from the inner wall of the inertial channel 2 toward the first mounting groove 11 , and the magnetic slider 4 is an arc-shaped slider matching the arc-shaped groove 211 .

[0046] like Figure 4 and Figure 5As shown, the outer wall of the annular protrusion 12 forms the inner wall of the inertia channel 2, and the outer wall of the base 1 forms the outer wall of the inertia channel 2. An arc groove 211 recessed toward the first mounting groove 11 can be opened from the outside to the inside on the annular protrusion 12, and the magnetic slider 4 is set as an arc slider matching the arc groove 211. When the solenoid valve core 3 and the magnetic slider 4 are attracted to each other and drive the magnetic slider 4 to slide or rotate, the magnetic slider 4 can be completely placed in the arc groove 211, and the inertia channel 2 can be a complete annular flow channel. At this time, the flow channel cross-section is maximized.

[0047] In addition to the above-mentioned arc groove 211 (to form the maximum flow channel cross section), the second mounting groove 21 also includes a space in the annular channel radially corresponding to the arc groove 211, so that the magnetic slider 4 can slide or rotate in the second mounting groove 21 to adjust the flow channel cross section of the inertial channel 2.

[0048] In this embodiment, the first mounting groove 11 and the inertial channel 2 are separated by the annular protrusion 12, and an arc groove 211 is opened on the annular protrusion 12, which is convenient for processing, and the distance between the arc groove 211 and the first mounting groove 11 is small, which can effectively reduce the distance between the solenoid valve core 3 and the magnetic slider 4, ensuring that the two are attracted by opposite charges and repelled by like charges, thereby achieving a faster attenuation of the powertrain and road excitation; at the same time, it can reduce the overall volume and weight of the suspension structure, and facilitate the arrangement of the suspension structure in the whole vehicle.

[0049] In a specific implementation, according to actual needs, a first mounting groove 11 can be set in the center of the base 1, an annular inertial channel 2 can be set near the outer side of the base 1, and an arc-shaped groove 211 recessed toward the first mounting groove 11 is opened inward from the inner wall of the inertial channel 2, that is, other components can be set between the inertial channel 2 and the first mounting groove 11 according to the actual situation of the suspension structure.

[0050] In some embodiments, a mounting support 22 is provided in the second mounting groove 21, and the magnetic slider 4 is sleeved on the mounting support 22, so that the magnetic slider 4 can rotate around the mounting support 22, thereby improving the controllability of the flow channel cross section adjustment of the inertial channel 2, that is, the adjustment size of the flow channel cross section can be determined by controlling the rotation angle of the magnetic slider 4. In this embodiment, the magnetic slider 4 rotates to adjust the damping angle within the range of (0° to 100°), which is larger than the adjustment range of the traditional suspension structure.

[0051] In a specific implementation, the magnetic slider 4 can also swing in the second mounting groove 21. Alternatively, an arc profile can also be provided in the second mounting groove 21, and when the electromagnetic valve core 3 and the magnetic slider 4 interact with each other, they can slide along the arc profile, thereby adjusting the flow channel cross section in the inertial channel 2.

[0052] In some embodiments, there are multiple magnetic sliders 4, and the multiple magnetic sliders 4 are evenly distributed along the circumference of the inertial channel 2, and the electromagnetic valve core 3 includes multiple magnetic parts 31 corresponding to the multiple magnetic sliders 4. Each magnetic part 31 interacts with a magnetic slider 4, and different magnetic forces can be provided between the magnetic slider 4 and the electromagnetic valve core 3 by using the one-to-one cooperation of the multiple magnetic sliders 4 and the multiple magnetic parts 31 arranged in a dispersed manner, so that the flow channel cross section can be adjusted within a large range, thereby adjusting the damping angle, and ensuring the uniformity of the force between the electromagnetic valve core 3 and the magnetic slider 4.

[0053] like Figure 5 As shown, the initial position of each magnetic slider 4 in the second mounting groove 21 can be set to be different, for example, the first magnetic slider 41 is completely placed in the first arc groove, and the second magnetic slider 42 is partially placed in the second arc groove.

[0054] In some embodiments, there are four magnetic sliders 4 , the solenoid valve core 3 is in a four-leaf clover structure, and the solenoid valve core 3 includes four magnetic parts 31 , so as to utilize fewer magnetic sliders 4 and magnetic parts 31 to meet the vibration requirements of the entire vehicle.

[0055] In a specific implementation, the number of magnetic sliders 4 can also be set to be more or less. When the number of magnetic sliders 4 is less, the volume of the sliders 4 may need to be set larger to meet the vibration requirements of the entire vehicle; when the number of magnetic sliders 4 is more, the adjustment range of the flow channel cross section may be too fine. For example, the solenoid valve core 3 can be in the shape of a "M", and eight magnetic sliders 4 are evenly distributed around the circumference of the inertial channel 2.

[0056] In some embodiments, Figures 3 to 6 As shown, the top of the base 1 is open, and the suspension structure also includes a flow channel cover plate 5 arranged on the top of the base 1, the flow channel cover plate 5 covers the inertial channel 2, and the flow channel cover plate 5 is provided with a liquid inlet 51 connected to the inertial channel 2, and the bottom of the base 1 is provided with a liquid outlet 13 connected to the inertial channel 2.

[0057] like Figure 3 As shown, the flow channel cover plate 5 is an annular cover plate matching the inertial channel 2, and the inertial channel 2 covered with the flow channel cover plate 5 forms a lower liquid chamber of the suspension structure.

[0058] In some embodiments, one of the base 1 and the flow channel cover plate 5 is provided with a positioning pin 61 , and the other is provided with a positioning groove 62 , so as to achieve rapid installation and positioning of the flow channel cover plate 5 .

[0059] like Figure 4As shown, in this embodiment, a positioning pin 61 is provided on the left and right sides of the top of the annular protrusion 12 in the base 1, and two positioning grooves 62 are provided on the flow channel cover plate 5 to be plugged and matched with the two positioning pins 61. The magnetic slider 4 is placed on the mounting pillar 22 in the inertial channel 2, and the positioning groove 62 of the flow channel cover plate 5 is interference-fitted with the positioning pin 61 on the annular protrusion 12, encapsulating and fixing the magnetic slider 4, and the base 1 with the inertial channel 2, the electromagnetic valve core 3, the magnetic slider 4 and the flow channel cover plate 5 cooperate to form a base assembly.

[0060] In a specific implementation, the flow channel cover plate 5 may also be a complete cover plate that is completely matched with the base 1 , that is, the flow channel cover plate 5 may cover the solenoid valve core 3 to protect the solenoid valve core 3 .

[0061] In some embodiments, Figures 1 to 3 As shown, the suspension structure also includes a rubber component 7, which is installed on the top of the base 1. The rubber component 7 includes an inner core 71, a rubber body 72 and an inner bracket 73. The inner core 71 is installed in the rubber body 72 from the top of the rubber body 72, and the inner bracket 73 is installed at the bottom of the rubber body 72 from the bottom of the rubber body 72. An upper liquid chamber connected to the inertial channel 2 is formed in the rubber component 7.

[0062] The upper and lower ends of the rubber body 72 are open to form a cavity, and the inner core 71 is installed in the rubber body 72 and connected to the engine of the vehicle. The power generated by the engine can be effectively transmitted to the rubber body 72 through the inner core 71 for shock absorption. The inner bracket 73 is used to support the rubber body 72 to increase the reliability and service life of the rubber body 72.

[0063] Furthermore, the inner bracket 73 and the rubber body 72 are vulcanized into one body, and the inner core 71 and the rubber body 72 are vulcanized and bonded.

[0064] The inner bracket 73 is placed in the rubber body 72 through a high temperature vulcanization process; the inner core 71 is bonded to the rubber body 72 through a vulcanization process, and after being assembled with the base components, the inner core 71, the rubber body 72 and the inner bracket 73 are connected together through a vulcanization process to form a rubber component 7, which has a simple and compact structure and is light in weight, and can effectively reduce the power consumption of the vehicle and improve the fuel efficiency of the vehicle.

[0065] In some embodiments, Figures 1 to 3 As shown, the suspension structure further comprises a bottom bowl 8 mounted on the bottom of the base 1 .

[0066] When the electromagnetic valve core 3 controls the magnetic slider 4 to be completely located in the arc groove 211 in the inertial channel 2, the liquid flow path in the inertial channel 2 reaches the maximum. At this time, the upper and lower liquid chambers are regarded as the same structure, and the vibration energy is absorbed by the deformation of the bottom bowl 8, thereby improving the vibration absorption effect of the suspension structure.

[0067] Optionally, the bottom bowl 8 is a rubber bottom bowl, which is light in weight, reduces the overall weight of the suspension structure, and can provide a better vibration absorption effect. The bottom bowl 8 can also be made of other flexible materials, such as carbon fiber.

[0068] In some embodiments, Figure 1 As shown, the suspension structure further includes a shell 9, which serves as the main frame of the suspension structure and protects other components. The shell 9 can bear a relatively high load, reasonably distribute the load borne by the suspension structure, and extend the service life of the suspension structure. The rubber component 7, the base component, and the bottom bowl 8 can be fastened in the shell 9 by press-fitting.

The vehicle corresponds to the suspension structure of the above-mentioned embodiment.
