[0029] Example

[0030] In this embodiment, the electromagnetic buffer structure can be placed between the vehicle body and the wheel assembly to buffer the impact force transmitted to the vehicle body from uneven road surfaces and attenuate the resulting vibration, so as to ensure vehicle body stability and enable the vehicle to drive smoothly.

[0031] Figure 2 This is a schematic diagram of an electromagnetic buffer structure provided in an embodiment of the present invention. The electromagnetic buffer structure in this embodiment includes a buffer body 1 and a piston connecting part 2. The buffer body 1 includes a suspension cavity 11 and a through hole 12 communicating with the suspension cavity 11. The piston connecting part 2 includes a piston head 21 and a connecting rod 22. The piston head 21 is disposed in the suspension cavity 11, and the connecting rod 22 is connected to the piston head 21. The connecting rod 22 passes through the through hole 12.

[0032] The piston head 21 is provided with a piston electromagnetic component 3 on its outer surface and a suspension cavity electromagnetic component 4 is provided on the inner wall of the buffer body 1. The piston electromagnetic component 3 and the suspension cavity electromagnetic component 4 are arranged opposite to each other, and the same magnetic poles of the piston electromagnetic component 3 and the suspension cavity electromagnetic component 4 are opposite to each other.

[0033] Specifically, the wheel assembly includes a wheel and structures connected to the wheel such as a cantilever, frame, and stabilizer bar. In some embodiments, the main body 1 of the electromagnetic buffer structure can be connected to the vehicle body via a buffer connector, and the piston connector 2 can be connected to the frame or cantilever of the wheel assembly. In this embodiment, the piston electromagnet 3 and the suspension cavity electromagnet 4 within the electromagnetic buffer structure are arranged opposite to each other, and both are coil electromagnets. When energized, the piston electromagnet 3 and the suspension cavity electromagnet 4 become magnetic, with their like poles facing each other. The piston connector 2 is suspended within the main body 1 by the repulsion between the like poles of the piston electromagnet 3 and the suspension cavity electromagnet 4. When the vehicle vibrates or shakes, the repulsive force between the piston electromagnet 3 and the suspension cavity electromagnet 4 can be controlled to obtain repulsive forces in different directions, changing the suspension position of the piston connector 2 within the main body 1, thereby reducing vibration and achieving vehicle stability.

[0034] In some embodiments, the piston head 21 of the piston connecting part 2 can be a cylinder; in other embodiments, the piston head 21 can be a polygonal column structure such as a rectangular column, pentagonal column, or hexagonal column. The cross-sectional shape of the suspension cavity 11 can be the same as the cross-sectional shape of the piston head 21. In this embodiment, setting the piston head 21 as a polygonal column is beneficial for placing the piston electromagnetic component 3 on different outer surfaces of the piston head 21. When the vehicle is traveling on an uneven road surface and is subjected to vibrations and impacts from different directions, the piston head 21 can obtain repulsive forces in different directions, thereby canceling out the vibration direction and reducing vibrations and impacts more efficiently.

[0035] Specifically, the buffer body 1 includes a side wall 13, one end of which has a first inner wall 14, and the other end has a second inner wall 15, with a through hole 12 in the second inner wall 15. The connecting rod 22 passes through the through hole 12 and is inserted into the buffer body 1.

[0036] Specifically, such as Figure 2-4 As shown, the piston head 21 includes a first end face 211 and a second end face 212 disposed opposite to each other. The first end face 211 is provided with a first piston electromagnetic component 31, and the second end face 212 is provided with a second piston electromagnetic component 32. The inner wall of the buffer body 1 is provided with a first suspension cavity electromagnetic component 41 opposite to the first piston electromagnetic component 31 and a second suspension cavity electromagnetic component 42 opposite to the second piston electromagnetic component 32.

[0037] In this embodiment, when the vehicle vibrates up and down, the magnetic field between the first end face 211 and the first inner wall portion 14 and the second end face 212 and the second inner wall portion 15 can be increased by changing the current in the coils of the first piston electromagnetic component 31 and the first suspension cavity electromagnetic component 41 and the second piston electromagnetic component 32 and the second suspension cavity electromagnetic component 4, thereby reducing the displacement of the vehicle body moving up and down and achieving vehicle body stability.

[0038] Specifically, the connecting rod 22 is fixed to the second end face 212, and at least two second piston electromagnetic elements 32 are provided on the second end face 212. A second suspension cavity electromagnetic element 42 corresponds one-to-one with the second piston electromagnetic elements 32, and the second suspension cavity electromagnetic elements 42 are disposed on the second inner wall portion 15. In some embodiments, two second piston electromagnetic elements 32 are provided on the second end face 212, and the two second piston electromagnetic elements 32 are respectively disposed on both sides of the connecting rod 22. The two second suspension cavity electromagnetic elements 42 are respectively disposed on both sides of the through hole 12. In this embodiment, two second piston electromagnetic elements 32 are provided on the second end face 212, and the two second piston electromagnetic elements 32 are respectively disposed on the second end face 212 on both sides of the connecting rod 22, so that the magnetic field distribution at the bottom of the piston head 21 is uniform, increasing the suspension stability of the piston connecting portion 2, thereby improving the stability of the electromagnetic buffer structure.

[0039] Specifically, a third piston electromagnetic component 33 is provided on the side 213 of the piston head 21, and a third suspension cavity electromagnetic component 43 is provided on the side wall 13 of the buffer body 1, opposite to the third piston electromagnetic component 33. The third piston electromagnetic component 33 and the third suspension cavity electromagnetic component 43 have the same magnetic poles facing each other. When the vehicle is subjected to vibration or impact from the side, the magnetic field between the third piston electromagnetic component 33 and the third suspension cavity electromagnetic component 43 on the side with the same direction of vibration or impact can be increased to increase the mutual repulsive force between the piston connection part 2 and the buffer body 1 in the direction of vehicle movement, thereby reducing the displacement of the vehicle body and achieving vehicle stability.

[0040] Specifically, the piston head 21 includes multiple side surfaces 213, each side surface 213 is provided with a third piston electromagnetic component 33, and the buffer body 1 includes multiple side wall portions 13 that are respectively opposite to the side surfaces 213, each side wall portion 13 is provided with a third suspension cavity electromagnetic component 43 that is opposite to the third piston electromagnetic component 33.

[0041] In some embodiments, when the piston head 21 is a rectangular prism, the piston head 21 includes four sides, and a third piston electromagnetic element 33 is provided on each side 213. A third suspension cavity electromagnetic element 43 is provided on the side wall 13 of the buffer body 1, which is one-to-one with the third piston electromagnetic element 33. When the vehicle is subjected to vibration or impact from the front-rear direction or the left-right direction, the vibration and displacement of the vehicle body can be reduced by controlling the increase or decrease of the magnetic field between the third piston electromagnetic element 33 and the third suspension cavity electromagnetic element 43, thereby achieving vehicle body stability. In this embodiment, the piston head is provided with multiple sides so that when the vehicle body vibrates and moves in different directions, the magnetic field between the third piston electromagnetic element 33 and the third suspension cavity electromagnetic element 43 in the corresponding direction can be changed according to the direction of vehicle body displacement, thereby reducing vibration and providing faster and more delicate dynamic adjustment.

[0042] Specifically, such as Figure 4As shown, a first guide electromagnetic component 34 is provided on the side of the connecting rod 22, and a second guide electromagnetic component 44 is provided on the wall of the through hole 12, which is opposite to the first guide electromagnetic component 34. The first guide electromagnetic component 34 and the second guide electromagnetic component 44 have the same magnetic poles facing each other, so that the connecting rod 22 can be suspended in the middle position of the through hole 12 and remain stable.

[0043] like Figure 1 As shown, this embodiment also provides an electromagnetic buffer system, including an electromagnetic controller 5, a body controller 8, and an electromagnetic buffer structure. One end of the electromagnetic controller 5 is communicatively connected to the body controller 8, and the other end of the electromagnetic controller 5 is connected to the piston electromagnetic component 3 and the suspension cavity electromagnetic component 4 of the electromagnetic buffer structure. The electromagnetic controller 5 is used to control the generation of magnetic fields by the piston electromagnetic component 3 and the suspension cavity electromagnetic component 4. Specifically, the electromagnetic controller 5 is used to control the connection, disconnection, and magnitude of the current in the coils of the piston electromagnetic component 3 and the suspension cavity electromagnetic component 4.

[0044] Specifically, the electromagnetic controller 5 includes a first electromagnetic control unit 51 and a second electromagnetic control unit 52. The first electromagnetic control unit 51 is connected to the piston electromagnetic component 3, and the second electromagnetic control unit 52 is connected to the suspension cavity electromagnetic component 4. The first electromagnetic control unit 51 includes multiple first electromagnetic control modules 511, the number of which is the same as the number of piston electromagnetic components 3. The multiple first electromagnetic control modules 511 are respectively connected to the first piston electromagnetic component 31, the second piston electromagnetic component 32, the third piston electromagnetic component 33, and the first guide electromagnetic component 34. The second electromagnetic control unit 52 includes multiple second electromagnetic control modules 521, the number of which is the same as the number of suspension cavity electromagnetic components 4. The multiple second electromagnetic control modules 521 are respectively connected to the first suspension cavity electromagnetic component 41, the second suspension cavity electromagnetic component 42, the third suspension cavity electromagnetic component 43, and the second guide electromagnetic component 44.

[0045] In this embodiment, the electromagnetic controller 5 controls the current in the coils of the piston electromagnetic component 3 and the suspension cavity electromagnetic component 4, thereby changing the magnetic force between opposing magnetic poles. This allows the system to provide different magnetic forces to counteract vibrations caused by bumps at different stages of the vehicle's movement. Compared to air suspension and spring suspension, the electromagnetic damping system in this embodiment provides faster and more precise dynamic adjustments.

[0046] In some implementations, the electromagnetic damping system of this embodiment can select different magnetic adjustment modes based on the user's selected driving mode, the user's dynamic driving habits, and / or road surface roughness. Generally, driving modes include off-road mode, racing mode, snow mode, and normal mode. The electromagnetic controller 5 controls the current in the coils of the piston electromagnetic component 3 and the suspension cavity electromagnetic component 4 according to the selected magnetic adjustment mode, thereby changing the magnitude of the magnetic field within the electromagnetic damping structure to obtain optimal shock absorption performance. For example, the electromagnetic buffer system can select different magnetic force adjustment modes according to the road surface bumps. If the ground is too bumpy, the flexible adjustment mode is selected. In the flexible adjustment mode, the current in the coils of the control piston electromagnetic component 3 and the suspension cavity electromagnetic component 4 is reduced, so that the repulsive force between the opposing piston electromagnetic component 3 and the suspension cavity electromagnetic component 4 is reduced to cope with the constantly bumpy road surface. If the road surface is flat, the rigid adjustment mode is selected. The current in the coils of the control piston electromagnetic component 3 and the suspension cavity electromagnetic component 4 is increased, so that the repulsive force between the opposing piston electromagnetic component 3 and the suspension cavity electromagnetic component 4 is increased, thereby increasing the rigidity of the electromagnetic buffer structure, improving the stability of the vehicle body, and avoiding vehicle body swaying due to insufficient magnetic force, which would affect driving stability.

[0047] In other implementations, the electromagnetic damping system can adjust the electromagnetic damping structure connected between the vehicle body and different wheel assemblies based on the user's selected driving mode, the user's dynamic driving habits, and / or road surface roughness. Specifically, the electromagnetic damping system adjusts the height of the electromagnetic damping structure by controlling the current in the coils of the piston electromagnetic component 3 and the suspension cavity electromagnetic component 4, thereby changing the magnetic field strength within the electromagnetic damping structure. For example, the electromagnetic damping system can provide more stable front-to-rear height changes by controlling the varying degrees of increase in the magnetic force of the electromagnetic damping structures installed on the four front and rear wheel assemblies. The electromagnetic damping system controls the height of the electromagnetic damping structure connected to the front wheel assembly to decrease, and the height of the electromagnetic damping structure connected to the rear wheel assembly to increase, thereby increasing downforce at the rear of the vehicle, resulting in stronger grip and improved vehicle stability.

[0048] In this embodiment, the vehicle body controller 8 is used to obtain information such as the vehicle's driving posture and tilt state. In some embodiments, the electromagnetic controller 5 adjusts the magnetic force between the buffer body 1 and the piston connection 2 in real time based on information such as the vehicle's driving posture and tilt state, thereby reducing vibration and achieving vehicle stability.

[0049] This embodiment also provides a vehicle, including a body 6, a wheel assembly 7, a vehicle chassis 9, and an electromagnetic buffer system; the electromagnetic buffer structure of the electromagnetic buffer system is disposed between the body 6 and the wheel assembly 7, and the electromagnetic controller 5 is disposed between the body 6 and the vehicle chassis 9. Specifically, the electromagnetic controller 5 is fixed on the body 6 and the vehicle chassis 9.

[0050] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
