[0025] Reference will now be made in detail to specific embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Although the present invention will be described in conjunction with specific embodiments, it will be understood that the present invention is not intended to be limited to those embodiments. On the contrary, it is intended to cover variations, modifications, and equivalents within the spirit and scope of the present invention as defined by the appended claims. It should be noted that the method steps described herein can be implemented by any functional block or functional arrangement, and any functional block or functional arrangement can be implemented as a physical entity or a logical entity, or a combination of the two.

[0026] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Note: The following example is only a specific example and is not intended to limit the embodiments of the present invention to the following specific steps, values, conditions, data, sequence, etc. Those skilled in the art can apply the concepts of the present invention to construct more embodiments not described in this specification by reading this specification.

[0028] Existing shock absorbers for vehicles are generally hydraulic, and hydraulic drive is achieved by filling the cylinder with hydraulic oil. However, since the shock absorber piston rod is a moving part, even with an oil seal, there will be oil leakage. Severe oil leakage will cause the shock absorber to fail and affect the driving safety of the vehicle.

[0029] In view of this, the present application provides a magnetically controlled shock absorber, which uses magnetic drive instead of hydraulic drive to achieve damping force on the up and down movement of the piston rod relative to the cylinder, thereby eliminating the oil leakage or oil seepage problem of traditional shock absorbers from the root, thereby ensuring the performance stability of the shock absorber and driving safety.

[0030] First, please refer to Figure 1The present application provides a magnetically controlled shock absorber, including a cylinder mechanism, a piston rod mechanism and a magnetic levitation mechanism, the cylinder mechanism including a cylinder 1, a cylinder mouth opened above the cylinder and an opening opened on the side of the cylinder; the piston rod mechanism including a piston rod 2, one end of the piston rod being a piston end, located in the cylinder, and the other end extending out of the cylinder mouth for connection with the vehicle body; the magnetic levitation mechanism including a magnetic controller 4, an upper magnetic element 21 and a lower magnetic element 11, the magnetic controller 4 is fixed at the opening, the upper magnetic element is fixed to the piston end of the piston rod, and the lower magnetic element is fixed to the bottom of the cylinder, the upper magnetic element and the lower magnetic element are electrically connected to the magnetic controller through a wire respectively, and the upper magnetic element and the lower magnetic element are electrically connected to the magnetic controller through a first wire 41 and a second wire 42 respectively.

[0031] The magnetically controlled shock absorber provided in the present application arranges upper and lower magnetic elements on the piston rod and the bottom of the cylinder. The magnetic controller controls the generation of magnetic force so that the piston rod slides relative to the cylinder under magnetic drive, replacing the traditional hydraulic oil drive method, effectively eliminating oil leakage or oil seepage problems caused by the shock absorber, and at the same time can realize dynamic control of the shock absorber's damping force, ensuring the comfort and operational stability of the vehicle during driving.

[0032] The magnetically controlled shock absorber provided in the present application has the other end of the piston rod connected to the vehicle body, and the bottom end of the shock absorber cylinder connected to the suspension swing arm. When the wheel bounces up and down, the piston rod will move up and down in the shock absorber cylinder. Due to the spring in the suspension system, the spring will cause the vehicle body to move up and down in simple harmonic motion. The shock absorber can provide a damping force for it, attenuate the aftershock generated by the spring, and thereby improve the comfort of the entire vehicle. An upper magnet is installed at the piston end of the piston rod, and a lower magnet is installed at the bottom of the shock absorber cylinder. The principle of magnetic levitation that like charges repel and opposite charges attract is utilized, and the damping force is provided to the shock absorber through the magnetic force between the upper and lower magnets. The magnetic control is provided by a magnetic controller. The magnetic controller utilizes the electromagnetic principle to control the magnetic force between the upper and lower magnets, that is, the damping force of the shock absorber, by changing the magnitude and direction of the current.

[0033] The magnetic shock absorber provided in this application no longer uses hydraulics to achieve the damping force on the up and down movement of the piston rod relative to the cylinder. Instead, it uses the principle of magnetic levitation to control the damping force of the up and down movement of the piston rod through the principle of magnetic repulsion or attraction between the upper magnetic element and the lower magnetic element, and realizes adjustable magnetic force, and then realizes adjustable damping force. This can improve the comfort and stability of vehicle driving, and completely avoid the problem of oil leakage in the shock absorber.

[0034] In one embodiment, the upper and lower magnetic elements are electromagnets, and are electrically connected to the upper and lower magnetic elements via a magnetic force controller that controls the magnitude or direction of the current supplied thereto, thereby generating a magnetic force. When the piston rod vibrates and moves toward the bottom of the cylinder due to an external force applied by the vehicle, the first and second electromagnets are controlled to generate like magnetic forces. The first and second electromagnets have the same magnetic poles at their respective ends, which repel each other and move away from each other, thereby generating a damping force on the piston rod as it approaches the bottom of the cylinder. When the piston rod vibrates and moves away from the bottom of the cylinder due to an external force applied by the vehicle, the first and second electromagnets are controlled to generate opposite magnetic forces. The first and second electromagnets have opposite magnetic poles at their respective ends, which attract each other and move toward each other, thereby generating a damping force on the piston rod as it moves away from the bottom of the cylinder. This prevents the vehicle from vibrating more significantly, thereby improving the driving experience and stability of the vehicle.

[0035] As mentioned above, the same-sex magnetic force is defined as the magnetic poles of the upper magnetic element and the lower magnetic element close to each other have the same magnetism, that is, the magnetic force direction of the upper magnetic element is opposite to the magnetic force direction of the lower magnetic element; the opposite-sex magnetic force is defined as the magnetic poles of the upper magnetic element and the lower magnetic element close to each other have opposite magnetism, that is, the magnetic force direction of the upper magnetic element is opposite to the magnetic force of the lower magnetic element.

[0036] Typically, the first conductive wire and the second conductive wire both include a tubular insulating sheath and an electric wire inserted into the insulating sheath.

[0037] In one embodiment, the insulating sleeve is made of elastic material so that when the piston rod of the shock absorber moves, the first wire repeatedly drives the piston rod to move with the ability to reset the deformation, making the shock absorber more durable.

[0038] In one embodiment, the first and second conductors are both spring-shaped, that is, the outer sheath is made of an insulating material, and an electrical conductor is disposed within the insulating sheath, which is twisted into a spring shape and has elastic reset capability. During the process of the upper magnetic element magnetically moving away from or approaching the lower magnetic element, the spring-shaped first and second conductors can achieve wire extension or reset compression within a limited space. Furthermore, during the process of the two magnetic elements magnetically attracting each other extremely close, the two conductors, under their own elastic action, can prevent collision impact losses caused by the upper and lower magnetic elements colliding with each other due to excessive proximity, thereby effectively ensuring the smoothness of the shock absorber's anti-seismic damping force, reducing the shock absorber's wear and tear, and effectively extending the shock absorber's service life.

[0039] In one embodiment, a guide seat 3 is provided at the mouth of the cylinder, and a guide seat hole is opened in the guide seat. The other end of the piston rod passes through the guide seat hole and extends out of the cylinder.

[0040] In one embodiment, the guide seat includes a seat body and a boss protruding from the seat body, wherein the boss is provided with a guide seat hole, and the boss with the guide seat hole guides the linear reciprocating movement of the piston rod relative to the cylinder.

[0041] In one embodiment, an acceleration sensor fixed on the cylinder and communicatively connected to the magnetic controller is further included, wherein the acceleration sensor is used to sense acceleration information of the shock absorber, and the magnetic controller is used to receive the acceleration information of the shock absorber.

[0042] In one embodiment, a displacement sensor is further included which is fixed to the tail of the piston rod and is in communication with the magnetic controller. The displacement sensor is used to sense the displacement information of the shock absorber, and the magnetic controller is used to receive the displacement information of the shock absorber.

[0043] Second, please refer to Figure 2 The present application provides a control method for the magnetically controlled shock absorber as described above, comprising the following steps:

[0044] Step S1, obtaining vehicle acceleration information and displacement information;

[0045] Step S2: Based on the acquired vehicle acceleration information and displacement information, the upper magnetic element and the lower magnetic element are controlled by a magnetic controller to generate homopolar or heteropolar magnetic forces.

[0046] The present application provides a control method applied to the above-mentioned magnetic controller, which has two purposes for controlling the shock absorber: first, to provide initial damping force, to provide partial damping force during the initial force stage of the spring, and to alleviate some road impact; second, to make the piston rod vibrate slightly near the design position, that is, the basic distance between the piston rod and the bottom of the cylinder, to attenuate the spring aftershock.

[0047] In one embodiment, the displacement information of the vehicle caused by vibration is indirectly obtained by sensing the displacement information between the upper magnetic element and the lower magnetic element.

[0048] In one embodiment, the step of controlling the upper magnetic element and the lower magnetic element to generate the same-sex or opposite-sex magnetic force by the magnetic controller according to the acquired vehicle acceleration information and displacement information specifically includes the following steps:

[0049] When the vehicle's acceleration exceeds the acceleration threshold and the vehicle's acceleration direction is upward, the magnetic controller controls the upper magnetic element and the lower magnetic element to generate the same magnetic force. The magnetic poles of the two magnetic elements close to each other are the same, and they repel each other, generating a damping force on the movement of the piston rod relative to the bottom of the cylinder.

[0050] When the vehicle's acceleration exceeds the acceleration threshold and the vehicle's acceleration direction is downward, the magnetic controller controls the upper magnetic element and the lower magnetic element to generate opposite magnetic forces. The magnetic poles of the two magnetic elements at the ends close to each other are opposite, and the magnetic attraction moves them closer to each other, generating a damping force that pushes the piston rod away from the bottom of the cylinder.

[0051] In one embodiment, an acceleration sensor is provided on the shock absorber cylinder for receiving acceleration signals generated by the impact of the road surface; a displacement sensor is provided at the tail end of the piston rod for real-time monitoring of the displacement information between the upper and lower magnetic elements; a magnetic controller is used to receive signals from the acceleration sensor and the displacement sensor, determine the magnitude and direction of the acceleration and displacement by receiving the signals, and control the upper and lower magnetic elements to generate magnetic forces of different magnitudes and directions by different received signals.

[0052] In one embodiment, in order to provide a damping force for small impacts on the vehicle, before the step of obtaining the vehicle acceleration information and displacement information, the following steps are further included:

[0053] The magnetic controller controls the upper and lower magnetic elements to generate reverse basic magnetic forces to maintain the basic spacing between the two magnetic elements. In the initial stage of the vehicle spring force, it provides initial damping force to alleviate some road impacts on the vehicle's driving surface, and makes the piston rod vibrate slightly near the position of the basic gap from the bottom of the cylinder, which plays a role in attenuating the spring aftershocks.

[0054] As described above, the small impact is defined as the acceleration information acquired by the acceleration sensor being smaller than the acceleration threshold or the displacement information acquired by the displacement sensor being smaller than the displacement threshold.

[0055] In one embodiment, to provide a damping force for large vehicle impacts, when a wheel is impacted by the road, an acceleration sensor detects the magnitude of the acceleration applied to the shock absorber cylinder in real time. If the acceleration exceeds a threshold, the acceleration sensor transmits the acceleration magnitude and direction signal to the magnetic controller. The acceleration direction (Z) is defined as positive, indicating that the wheel is impacted upward. The shock absorber is compressed and the piston rod approaches the bottom of the cylinder. Conversely, the acceleration direction (Z) is negative, indicating that the shock absorber is stretched and the piston rod moves away from the bottom of the cylinder. When the acceleration direction is positive, the magnetic controller controls the upper and lower magnetic elements to generate like magnetic forces, causing the piston rods to approach each other under the action of magnetic attraction. The magnitude of the magnetic force is calculated based on the magnitude of the acceleration:

[0056] F 磁 =ξ×a

[0057] Among them, F 磁 is the magnetic force between the upper magnetic element and the lower magnetic element, a is the acceleration received by the acceleration sensor, and ξ is the calculation coefficient.

[0058] As described above, the large impact is defined as the acceleration information acquired by the acceleration sensor being not less than the acceleration threshold or the displacement information acquired by the displacement sensor being not less than the displacement threshold.

[0059] When the acceleration direction is negative, the magnetic controller controls the upper and lower magnetic elements to generate opposite magnetic forces.

[0060] Among them, the purpose of controlling the size of the magnetic force is to offset part of the spring force, but it cannot offset it completely, otherwise the spring will lose its function of buffering impact; therefore, the calculation coefficient can be calibrated through adjustment to set a coefficient that meets the needs of the vehicle. For vehicles with higher comfort requirements, the shock absorber can provide smaller magnetic force to meet the comfort requirements. For vehicles with higher handling requirements, the shock absorber can provide larger magnetic force to quickly meet the handling requirements.

[0061] The above-mentioned magnetic control is the initial stage magnetic control. When the shock absorber is compressed to a certain extent, the acceleration will decrease. When the acceleration is lower than the acceleration threshold, it indicates that the wheel is not subjected to a large impact, and then the displacement sensor begins to work.

[0062] When the vehicle is stationary or driving steadily, there is a basic distance between the upper and lower magnetic elements. Based on this basic distance, if the displacement sensor detects that the distance between the upper and lower magnetic elements is greater than the basic distance, the displacement is defined as positive. If the distance between the upper and lower magnetic elements is less than the basic distance, the displacement is defined as negative.

[0063] In one embodiment, the magnetic controller also receives an acceleration signal and comprehensively determines that when the displacement signal is negative and the acceleration signal is positive, it indicates that the shock absorber is in a compression process. The upper and lower magnetic elements are controlled to generate magnetic forces with the same magnetic direction, that is, the upper magnetic element and the lower magnetic element are controlled to generate magnetic forces in opposite directions. The two magnetic elements repel each other with the same polarity and generate a compression damping force between the piston rod and the bottom of the cylinder.

[0064] When the displacement signal is positive or the acceleration signal is negative, the upper and lower magnetic elements are controlled to generate opposite magnetic forces, pushing the piston rod back to the original design displacement. For other signal intersections, the magnetic controller does not work.

[0065] The displacement sensor controls the shock absorber's small vibrations, while the acceleration sensor controls the shock absorber's response to large impacts. Prioritizing large impact vibrations over small vibrations, this ensures the relative distance between the piston rod and cylinder quickly returns to the designed position.

[0066] In one embodiment, please refer to Figure 3The step of “controlling the upper magnetic element and the lower magnetic element to generate homopolar or heteropolar magnetic forces through a magnetic controller according to the acquired vehicle acceleration information and displacement information” specifically includes the following steps:

[0067] When the vehicle is subjected to vibrations such as road impact, the acceleration information sensed by the shock absorber is obtained through the acceleration sensor fixed on the shock absorber cylinder;

[0068] When the acceleration information exceeds the acceleration threshold, the upper and lower magnetic elements are controlled by the magnetic controller according to the acceleration information to generate like or opposite magnetic forces. The piston rod and the bottom of the cylinder repel each other with like forces or attract each other with opposite forces. The piston rod moves away from or approaches the bottom of the cylinder, generating a damping force, increasing or decreasing the displacement, and restoring the basic spacing between the piston rod and the bottom of the cylinder to alleviate vibration.

[0069] When the acceleration does not exceed the acceleration threshold, the displacement information sensed by the displacement sensor fixed at the tail end of the piston rod is obtained. When the displacement information exceeds the displacement threshold, the upper and lower magnetic elements are controlled by the magnetic controller to generate homosexual or heterosexual magnetic forces based on the displacement information or the combined information of the displacement information and the acceleration data.

[0070] In one embodiment, the step of “controlling the upper and lower magnetic elements to generate same-sex or opposite-sex magnetic forces through a magnetic force controller according to acceleration information” specifically includes the following steps:

[0071] When the acceleration is positive, the upper and lower magnetic elements are controlled by the magnetic controller to generate magnetic forces in opposite directions. The piston rod and the bottom of the cylinder are attracted to each other with the same polarity. The piston rod moves away from the bottom of the cylinder, generating a damping force and increasing the displacement. The basic displacement between the piston rod and the bottom of the cylinder is restored, thus alleviating vibration.

[0072] When the acceleration is negative, the magnetic controller controls the upper and lower magnetic elements to generate magnetic forces in the same direction. The piston rod and the bottom of the cylinder are attracted to each other, and the piston rod approaches the bottom of the cylinder, generating damping force, reducing displacement and alleviating vibration.

[0073] In one embodiment, the step of “controlling the upper and lower magnetic elements to generate same-sex or opposite-sex magnetic forces through a magnetic force controller according to the displacement” specifically includes the following steps:

[0074] When the displacement is positive, the magnetic controller controls the upper and lower magnetic elements to generate opposite magnetic forces, that is, magnetic forces with the same direction. The piston rod and the bottom of the cylinder are attracted to each other, and the piston rod approaches the bottom of the cylinder, generating damping force, reducing displacement and alleviating vibration.

[0075] When the displacement is negative, the magnetic controller controls the upper and lower magnetic elements to generate like magnetic forces, that is, magnetic forces in opposite directions. The piston rod and the bottom of the cylinder are attracted to each other, and the piston rod moves away from the bottom of the cylinder, generating damping force, increasing the displacement, and restoring the basic displacement between the piston rod and the bottom of the cylinder, thereby alleviating vibration.
