[0002] With the booming development of the new energy vehicle industry, the requirements for vehicle performance are also increasing day by day. Among them, the performance of shock absorbers is directly related to the driving smoothness and riding comfort of vehicles. Most traditional new energy vehicle shock absorbers adopt hydraulic or pneumatic designs, and absorb and relieve the vibrations generated during vehicle driving through the flow and compression of oil or gas. These shock absorbers can improve the driving quality of vehicles to a certain extent, but their performance is often limited by fixed damping characteristics and adjustment ranges.

[0003] Although adaptive shock absorbers have shown great potential in the field of new energy vehicles, there are still some deficiencies in existing adaptive shock absorbers. On the one hand, the execution accuracy of some adaptive shock absorbers is limited, resulting in inaccurate monitoring and feedback of vehicle driving conditions and road surface conditions, thereby affecting the adjustment accuracy and response speed of the damping characteristics of shock absorbers; on the other hand, the designs of some adaptive shock absorbers are too complex, which not only increases the manufacturing cost, but also may lead to reduced reliability and increased difficulty in maintenance and repair.

[0023] Example 1: Refer to Figures 1-8, an intelligent adaptive shock absorber for new energy vehicles, comprising a shock absorber oil cylinder 1, a piston rod 12 and a piston block 15, and further comprising: the piston block 15 slides inside the shock absorber oil cylinder 1, and the piston rod 12 is fixedly connected to the piston block 15; an adjusting part 2 is arranged outside the shock absorber oil cylinder 1, the top of the piston rod 12 is fixedly connected with a top plate 3, a first spring 6 is arranged between the top plate 3 and the adjusting part 2, a bottom cylinder 7 and a lifting ring 8 are respectively arranged inside the first spring 6, the lifting ring 8 slides inside the bottom cylinder 7, and the bottom cylinder 7 is fixed on the shock absorber oil cylinder 1; the upper part of the piston rod 12 is sleeved with a second spring 9, the top of the second spring 9 is fixedly connected with the top plate 3, and the bottom of the second spring 9 is fixedly connected with a bottom plate 10; a plurality of overflow holes 1501 are formed in the piston block 15 in a circumferential distribution, a flow regulating plate 16 is slidably connected to the piston block 15, and through holes 1601 corresponding to the plurality of overflow holes 1501 are formed in the flow regulating plate 16; a fixing ring 1602 is arranged at the inner ring part of the flow regulating plate 16, and an annular groove 17 for accommodating the fixing ring 1602 is formed in the piston rod 12; a plurality of moving grooves 29 communicated with the annular groove 17 are formed in the piston rod 12, a fixing baffle 31 fixedly connected with the fixing ring 1602 slides in the moving grooves 29, and a tension spring 30 respectively connected with the fixing baffle 31 and the end part of the moving groove 29 is arranged in the moving groove 29; a limiting rod 14 is arranged inside the shock absorber oil cylinder 1, an inner channel 13 is formed in the central parts of the piston rod 12 and the piston block 15, and an infusion channel 28 communicated with the moving groove 29 is formed in the inner channel 13.

[0024] In the present invention, in the initial state, the piston block 15 is located at the uppermost part or the upper middle part of the shock absorber oil cylinder 1, which depends on the specific requirements and uses of the vehicle and is not limited herein; When the vehicle is driving on a flat road surface, the impact force received by the wheels is small, so the force received by the shock absorber spring will also be correspondingly reduced. At this time, mainly the first spring 6 acts, the impact force received by the first spring 6 is small, the limiting rod 14 slowly inserts into the inner channel 13, the flow regulating plate 16 does not move, the overflow holes 1501 and the through holes 1601 are not completely opposite, maintaining a small aperture and a large damping force, so that when the vehicle is driving on a relatively flat road surface, the vehicle's controllability is improved; When the vehicle is driving on a bumpy road surface, the impact on the wheels is relatively large. Therefore, the force on the shock absorber spring will also increase accordingly. At this time, the first spring 6 and the second spring 9 act together to absorb and disperse energy jointly. This dual action can more effectively reduce the vibration amplitude and improve the shock absorption effect. At the same time, the limiting rod 14 quickly inserts into the inner channel 13, and some of the medium in the shock absorber oil cylinder 1 will enter the movable groove 29, pushing the fixed baffle 31, causing the flow regulating plate 16 to rotate, and then making the through hole 1601 face the overflow hole 1501 exactly, so that the channel aperture formed by the overflow hole 1501 and the through hole 1601 increases (the maximum aperture is when the overflow hole 1501 and the through hole 1601 are completely opposite), the damping force decreases. When the vehicle encounters a large bump or impact, it can quickly absorb and disperse these forces, making the vehicle drive more smoothly. The channel aperture size (damping force size) formed by the overflow hole 1501 and the through hole 1601 changes according to the force on the wheels (i.e., the force on the first spring 6), thereby improving the riding comfort. Please refer to Figure 3 ; By dynamically adjusting the damping, this shock absorber can better adapt to various road conditions and driving conditions, which helps to reduce the wear and fatigue of the suspension system and extend the service life of the shock absorber and other related components.

[0025] Embodiment 2: Refer to Figures 1-8 , which is basically the same as Embodiment 1. Furthermore: The top end of the top plate 3 is fixedly connected with a top cap 4, and the bottom end of the shock absorber oil cylinder 1 is fixedly connected with a bottom connector 5; The bottom cylinder 7, the lifting ring 8 and the bottom plate 10 are all sleeved on the piston rod 12, and a third spring 11 is arranged in the bottom cylinder 7; The bottom cylinder 7 is divided into two layers of clamping plates. Among them, a retreat groove 23 is opened on the clamping plate of the bottom cylinder 7 that fits the piston rod 12. A block 24 is slidably connected in the retreat groove 23. A retreat rod 26 is fixedly connected to the block 24. A fourth spring 25 is sleeved on the retreat rod 26. The end of the retreat rod 26 extending into the bottom cylinder 7 is provided with a limit block 27; A first through pipe 21 is opened in the clamping plate of the bottom cylinder 7 that fits the piston rod 12. One end of the first through pipe 21 is communicated with the inside of the bottom cylinder 7, and the other end of the first through pipe 21 is communicated with the retreat groove 23. A second through pipe 22 is opened in the clamping plate of the bottom cylinder 7 that fits the piston rod 12. One end of the second through pipe 22 is communicated with the retreat groove 23, and the other end of the second through pipe 22 extends to the outside. Among them, the ports of the first through pipe 21 and the second through pipe 22 placed in the retreat groove 23 are exactly opposite; The end of the retreat groove 23 facing the piston rod 12 is an opening; A receiving groove 18 communicated with the inner channel 13 is opened in the middle of the piston rod 12. A slider 19 is slidably connected in the receiving groove 18. The part of the inner channel 13 extending above the receiving groove 18 is communicated with an air delivery pipe 20, and the air delivery pipe 20 corresponds to the opening of the retreat groove 23; A liquid discharge hole 1301 and a liquid injection hole 1302 are opened in the inner channel 13 from top to bottom in sequence. The liquid injection hole 1302 is communicated with the liquid injection channel 28.

[0026] The lifting ring 8 moves on the bottom cylinder 7. In the initial state, the limiting rod 14 is at the port of the inner channel 13 at the bottom of the piston block 15. Specifically, when the vehicle is driving on a flat road surface, the impact on the wheels is small. Therefore, the force on the shock absorber spring will also decrease accordingly. The top plate 3 compresses the first spring 6 with a small force, and the limiting rod 14 slowly enters the inner channel 13. The limiting rod 14 discharges the medium in the inner channel 13 through the liquid discharge hole 1301. At this time, when the top plate 3 moves downward, it squeezes the bottom plate 10. The bottom plate 10 presses down the lifting ring 8, and the lifting ring 8 compresses the third spring 11. The lifting ring 8 retracts into the bottom cylinder 7. During the process of the lifting ring 8 retracting into the bottom cylinder 7, the air in the bottom cylinder 7 is discharged to the outside through the first connecting pipe 21, the retreat groove 23, and the second connecting pipe 22. The second spring 9 and the third spring 11 have relatively weak compression resistance. When the vehicle is driving on a bumpy road surface, the impact on the wheels is large. Therefore, the force on the shock absorber spring will also increase accordingly. The top plate 3 compresses the first spring 6 with a large force, and the limiting rod 14 quickly enters the inner channel 13. The limiting rod 14 squeezes a large amount of the medium in the inner channel 13. However, the aperture of the liquid discharge hole 1301 is small, and most of the medium cannot be discharged through the liquid discharge hole 1301. The pressure in the inner channel 13 increases, and part of the medium is discharged into the movable groove 29 through the liquid infusion hole 1302 and the liquid infusion channel 28. The medium entering the movable groove 29 pushes the fixed baffle 31, and then drives the flow regulating plate 16 to rotate, so that the aperture of the channel formed by the overflow hole 1501 and the through hole 1601 increases, and the damping force decreases. There is also part of the medium that pushes the slider 19 upward, so that the slider 19 discharges the air in the accommodating groove 18 to the air pipe 20. The air in the air pipe 20 enters the retreat groove 23 and pushes the stop block 24 to compress the fourth spring 25. The stop block 24 moves in the direction of the fourth spring 25 and finally blocks between the first connecting pipe 21 and the second connecting pipe 22, making the first connecting pipe 21 and the second connecting pipe 22 not communicate. At this time, when the top plate 3 moves downward and squeezes the bottom plate 10, the bottom plate 10 presses down the lifting ring 8. Since the first connecting pipe 21 and the second connecting pipe 22 do not communicate, the air in the bottom cylinder 7 cannot be discharged quickly in time. During the continuous downward movement of the top plate 3, the resistance increases, and the air in the bottom cylinder 7 can only be discharged through the gap between the bottom cylinder 7 and the lifting ring 8. The second spring 9, the third spring 11, the bottom cylinder 7, and the lifting ring 8 form the second external elastic member. Cooperating with the first spring 6, when subjected to a large force impact, the above two elastic parts (the second spring 9, the third spring 11, the bottom cylinder 7, the lifting ring 8 form the second external elastic member and the first spring 6) will work simultaneously to jointly absorb and disperse energy, which can more effectively reduce the vibration amplitude and improve the damping effect. The limiting rod 14 continues to move upward. When the top of the limiting rod 14 exceeds the infusion hole 1302, the infusion hole 1302 is blocked, and the medium in the movable groove 29 cannot be discharged, so that the channel aperture formed by the adjusted overflow hole 1501 and the through hole 1601 remains unchanged. Furthermore, during the entire movement stroke, the shock absorber has a matching damping effect. At the same time, when the piston rod 12 moves downward, the air pipe 20 gradually no longer faces the retraction groove 23, and the gas in the retraction groove 23 cannot be discharged either, so that the first connecting pipe 21 and the second connecting pipe 22 always remain disconnected. It should be noted that in the second elastic member composed of the second spring 9, the third spring 11, the bottom cylinder 7, and the lifting ring 8, when the second spring 9 is compressed to the maximum extent, the third spring 11, the bottom cylinder 7, and the lifting ring 8 start the next work. Correspondingly, the air pipe 20 does not face the retraction groove 23 immediately (initially, the air pipe 20 is above the retraction groove 23). When the air pipe 20 moves down to the lowest position, the opening of the air pipe 20 will not contact the medium in the shock absorber oil cylinder 1. Since the second elastic member composed of the second spring 9, the third spring 11, the bottom cylinder 7, and the lifting ring 8 does not participate in the work under the impact of a small force, its service life is relatively extended. This reduces the frequency of spring replacement and lowers the maintenance cost. At the same time, the first spring 6 plays a major role in conventional vibrations and can also maintain a long service life. This design enables the shock absorber to adapt to vibrations of different amplitudes. Whether it is a slight vibration or a strong impact, the shock absorber can provide an appropriate damping effect.

[0027] Embodiment 3: Refer to Figures 1-8 , which is basically the same as Embodiment 2. Further, the fixing ring 1602 rotates in the ring groove 17, and the fixed baffle 31 only slides in the movable groove 29.

[0028] In the present invention, the fixing ring 1602 rotates in the ring groove 17, and the fixing ring 1602 fits tightly with the ring groove 17 to prevent the medium in the movable groove 29 from running out. By dynamically adjusting the damping, the shock absorber can better adapt to different driving conditions. When driving at high speed or turning, increasing the damping force can improve the vehicle's stability and handling, reducing roll and sway. When driving at low speed or encountering complex road conditions, reducing the damping force helps to improve the vehicle's passability and riding comfort. This shock absorber makes the vehicle's suspension system more efficient by dynamically adjusting the damping. With appropriate damping settings, the vehicle's suspension system can better absorb and disperse road vibrations, reducing unnecessary energy loss, which helps to reduce the vehicle's energy consumption and improve fuel economy.

[0029] Embodiment 4: Refer to Figures 1-8, which is basically the same as Embodiment 3. Further, the movable slot 29 is arc-shaped, and the fixed baffle 31 divides the movable slot 29 into two parts. The port of the infusion channel 28 placed in the movable slot 29 is always located in the part of the movable slot 29 with the tension spring 30.

[0030] In the present invention, the medium input through the infusion channel 28 pushes the fixed baffle 31, causing the tension spring 30 to be stretched, and the flow regulating plate 16 to rotate. After that, the tension spring 30 resets the fixed baffle 31. The bottom cylinder 7, the lifting ring 8, and the bottom plate 10 protect the piston rod 12 to prevent foreign objects from contaminating it.

[0031] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made. These are all equivalent modifications and evolutions of the above embodiments based on the essential technology of the present invention, and all fall within the protection scope of the present invention.
