Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an electronically controlled vibration damping mechanism and a vehicle. Background Technology

[0002] During vehicle operation, uneven road surfaces can cause vertical vibrations in the vehicle body, affecting ride comfort and handling stability. To suppress these vertical vibrations, electronically controlled shock absorbers are typically installed in the suspension system. These shock absorbers use damping force to dissipate vibration energy, thereby ensuring ride comfort and handling stability.

[0003] The electronically controlled shock absorber includes an outer cylinder, a piston rod, a piston valve, and a solenoid valve assembly. The piston rod is fixedly connected to the vehicle body, and the outer cylinder is connected to the suspension. When the outer cylinder moves relative to the piston rod, it drives the piston valve on the piston rod to reciprocate within the outer cylinder. Oil flows through the throttle orifice on the piston valve, generating damping force. The solenoid valve adjusts the opening of the throttle orifice by changing the current, thereby controlling the magnitude of the damping force in real time.

[0004] However, when the solenoid valve adjusts the opening of the throttle orifice, the sudden change in the flow rate of the oil through the throttle orifice will cause pressure fluctuations, which in turn will cause the piston rod to generate high-frequency vibration and noise, affecting the user experience. Utility Model Content

[0050] Unless otherwise stated, the term "multiple" means two or more.

[0051] During vehicle operation, uneven road surfaces can cause vertical vibrations in the vehicle body, affecting ride comfort and handling stability. To suppress these vertical vibrations, electronically controlled shock absorbers are typically installed in the suspension system. These shock absorbers use damping force to dissipate vibration energy, thereby ensuring ride comfort and handling stability.

[0052] The electronically controlled shock absorber includes an outer cylinder, a piston rod, a piston valve, and a solenoid valve assembly. The piston rod is fixedly connected to the vehicle body, and the outer cylinder is connected to the suspension. When the outer cylinder moves relative to the piston rod, it drives the piston valve on the piston rod to reciprocate within the outer cylinder. Oil flows through the throttle orifice on the piston valve, generating damping force. The solenoid valve adjusts the opening of the throttle orifice by changing the current, thereby controlling the magnitude of the damping force in real time.

[0053] However, when the solenoid valve adjusts the opening of the throttle orifice, the sudden change in the flow rate of the oil through the throttle orifice will cause pressure fluctuations, which in turn will cause the piston rod to generate high-frequency vibration and noise, affecting the user experience.

[0054] In view of this, this application provides an electronically controlled vibration damping mechanism and a vehicle. The electronically controlled vibration damping mechanism includes a damper, a support, and a limiting structure. The damper includes an outer cylinder, a dust cover, and a piston rod. The outer cylinder is movable relative to the dust cover along a first direction. The first end of the piston rod passes through the dust cover and is disposed inside the outer cylinder, and is fixed relative to the dust cover. The second end of the piston rod is located outside the dust cover. The support is sleeved on the second end and fixed relative to it, and the support is configured to connect to the vehicle body. The limiting structure is also sleeved on the second end and fixed relative to the support. The limiting structure is used to limit the displacement of the piston rod, thereby suppressing high-frequency vibration of the piston rod, avoiding noise caused by piston rod vibration, and improving the user experience.

[0055] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0056] Please refer to Figures 1 to 5 In one aspect, embodiments of this application provide an electronically controlled vibration damping mechanism, including a vibration damper 100, a support 200, and a limiting structure 300.

[0057] Specifically, the shock absorber 100 includes an outer cylinder 110, a dust cover 120, and a piston rod 130. The outer cylinder 110 is movable relative to the dust cover 120 along a first direction x. The first end of the piston rod 130 passes through the dust cover 120 and is located inside the outer cylinder 110, and is fixed relative to the dust cover 120. The second end 131 of the piston rod 130 is located outside the dust cover 120. A support 200 is fitted onto the second end 131 and fixed relative to it, and the support 200 is configured to connect to the vehicle body. The outer cylinder 110 is connected to the wheels through the vehicle's suspension system to dissipate the vibration energy generated during vehicle operation, ensuring ride comfort and handling stability.

[0058] The vehicle's suspension system is an existing structure and will not be described in detail here.

[0059] In this embodiment, a piston valve is provided on the piston rod 130, and the piston valve has multiple throttling orifices. The outer cylinder 110 is filled with hydraulic oil. When vibration occurs during vehicle operation, the outer cylinder 110 moves relative to the piston rod 130 along the first direction x, forcing the hydraulic oil to flow through the throttling orifices of the piston valve. The interaction between the piston valve on the piston rod 130 and the hydraulic oil in the outer cylinder 110 generates a damping force.

[0060] In this embodiment, the dust cover 120 is located on the outside of the outer cylinder 110 to prevent external contaminants from entering between the outer cylinder 110 and the piston rod 130, thereby extending the service life of the shock absorber 100.

[0061] Specifically, in this embodiment, the first direction x is the vertical direction of the vehicle body. When the vehicle travels on a raised road surface, such as a speed bump, the wheels are subjected to an upward impact force, causing the outer cylinder 110 to move relative to the piston rod 130 along the first direction x towards the second end 131. At this time, the hydraulic oil below the piston valve is squeezed against the piston valve by the outer cylinder 110 and passes upward through the throttle orifice, generating a damping force, thereby resisting the lifting movement of the wheel, suppressing the upward bounce of the wheel, reducing the bumpy feeling of the vehicle, and improving the driving stability of the vehicle.

[0062] When the vehicle travels on uneven road surfaces, such as potholes, the wheels will suddenly sink, causing the outer cylinder 110 to move away from the second end 131 relative to the piston rod 130 in the first direction x. At this time, the hydraulic oil above the piston valve is squeezed against the piston valve by the outer cylinder 110 and passes downward through the throttle orifice, generating damping force, thereby slowing down the wheel's descent speed, preventing the vehicle body from suddenly sinking, reducing the vehicle's bumpy feeling, and improving the vehicle's driving stability.

[0063] The piston valve is equipped with an electromagnetic control device, which controls the opening and closing of the throttle orifice to adjust the damping force of the shock absorber 100. A larger orifice opening reduces the flow resistance of the hydraulic oil at the piston valve, thus decreasing the damping force of the shock absorber 100. Conversely, a smaller orifice opening restricts the flow of hydraulic oil, increasing the pressure difference and consequently increasing the damping force of the shock absorber 100.

[0064] However, when the solenoid valve suddenly closes the throttle orifice, the hydraulic oil flowing at high speed is suddenly blocked, causing the kinetic energy of the hydraulic oil to be instantly converted into an impact load acting on the piston valve surface. The impact force is directly transmitted to the piston rod 130 through the piston valve, which causes the piston rod 130 to vibrate at high frequency. The vibration is transmitted to the vehicle body through the support 200, generating a lot of noise and affecting the user experience.

[0065] Therefore, the electronically controlled vibration damping mechanism provided in this embodiment also includes a limiting structure 300, which is also sleeved on the second end 131 and fixed relative to the support 200. The limiting structure 300 is used to limit the displacement of the piston rod 130, thereby preventing the piston rod 130 from generating excessive displacement when subjected to impact load. By limiting the displacement of the piston rod 130, the high-frequency vibration of the piston rod 130 can be effectively reduced, preventing the vibration from being transmitted to the vehicle body through the support 200, thereby avoiding the generation of large noise and improving the user experience.

[0066] Specifically, in this embodiment, the limiting structure 300 is made of a flexible material and has a certain degree of elasticity. When the impact force on the piston rod 130 is transmitted to the second end 131, the limiting structure 300 can absorb part of the vibration energy and disperse the vibration energy through its elastic properties, thereby reducing the vibration amplitude of the piston rod 130 and preventing the vibration of the piston rod 130 from being transmitted to the vehicle body through the support 200, thus avoiding the generation of large noise and improving the user experience.

[0067] In this embodiment, the electromagnetic control device includes a recovery solenoid valve 140 and a compression solenoid valve 150. The recovery solenoid valve 140 can control the recovery damping force of the electronically controlled vibration damping mechanism, and the compression solenoid valve 150 can control the compression damping force of the electronically controlled vibration damping mechanism, thereby enabling the electronically controlled vibration damping mechanism to adjust the damping force in the recovery and compression stages more accurately according to the vehicle's driving state and road conditions.

[0068] In addition, in this embodiment, a bushing is provided at the end of the outer cylinder 110 that is connected to the vehicle suspension system, so as to absorb and buffer the vibration and impact from the suspension system, thereby further improving the driving comfort of the vehicle.

[0069] In this embodiment, the bushing is made of rubber material. In other embodiments, an adaptive selection can be made according to actual needs. This embodiment does not impose any restrictions on this.

[0070] Please refer to Figures 1 to 5 In some embodiments, the limiting structure 300 includes a buffer 310, which is sleeved on the second end 131 and located between the support 200 and the dust cover 120. One end of the buffer 310 is connected to and fixed relative to the support 200, and the other end of the buffer 310 is fixed relative to the outer cylinder 110. At least a portion of the inner wall of the buffer 310 contacts the circumferential outer wall of the second end 131.

[0071] Specifically, when the piston rod 130 vibrates due to impact load, since the first end of the piston rod 130 passes through the dust cover 120 and is fixed relative to the dust cover 120, the vibration of the piston rod 130 will cause the dust cover 120 to vibrate together. By positioning the buffer 310 between the support 200 and the dust cover 120, the vibration of the dust cover 120 can be absorbed, thereby preventing the vibration of the dust cover 120 from being transmitted to the support 200.

[0072] Meanwhile, in this embodiment, at least a portion of the inner wall of the buffer 310 contacts the circumferential outer wall of the second end 131. When the piston rod 130 vibrates, the friction between the inner wall of the buffer 310 and the outer wall of the piston rod 130, as well as the elastic deformation of the buffer 310, can work together on the piston rod 130, thereby further absorbing and dispersing vibration energy, avoiding the concentration of vibration energy, limiting the displacement of the piston rod 130, thus ensuring the reliability and stability of the electronically controlled vibration damping mechanism, reducing the noise generated by the vibration of the piston rod 130, and improving the user experience.

[0073] Furthermore, in this embodiment, since at least a portion of the inner wall of the buffer 310 contacts the circumferential outer wall of the second end 131, the contact area between the buffer 310 and the second end 131 can be reduced, thereby avoiding frictional noise generated between the second end 131 and the buffer 310 during vibration, and further reducing the noise generated by the electronically controlled vibration damping mechanism.

[0074] In this embodiment, the buffer 310 is made of polyurethane material. In other embodiments, the material and manufacturing process of the buffer 310 can also be adapted to the choice. This embodiment does not impose any restrictions on this.

[0075] Please refer to Figures 1 to 5 In some embodiments, the inner wall of the buffer 310 has a support group, which includes one or more support portions 311. The multiple support portions 311 are spaced apart along the circumferential direction of the buffer 310, and the support portions 311 are in contact with the circumferential outer wall of the second end 131.

[0076] Specifically, in this embodiment, a support group is provided on the inner wall of the buffer 310. The support group includes multiple support parts 311. The support parts 311 are in contact with the circumferential outer wall of the second end 131. The support parts 311 are protrusions on the inner wall of the buffer 310 that protrude toward the piston rod 130, thereby forming point contact with the second end 131. In this way, while absorbing the vibration energy of the second end 131 through the buffer 310, the contact area between the buffer 310 and the second end 131 can be reduced, thereby avoiding abnormal noise caused by friction between the buffer 310 and the second end 131.

[0077] The number of support parts 311 can be selectively set according to actual needs, and this embodiment does not impose any restrictions on this.

[0078] In some embodiments, the electronically controlled vibration damping mechanism further includes a snap-fit ​​member 500, which is an annular structure. A first snap-fit ​​groove 312 is provided on the buffer member 310, and the snap-fit ​​member 500 is embedded in the first snap-fit ​​groove 312. A second snap-fit ​​groove 510 is also provided on the snap-fit ​​member 500. The end of the dust cover 120 near the second end 131 is snapped into the second snap-fit ​​groove 510. This not only fixes the dust cover 120, but also allows the vibration of the dust cover 120 to be transmitted to the buffer member 310 through the snap-fit ​​member 500, thereby further reducing the transmission of vibration and thus reducing the noise generated by vibration.

[0079] Please refer to Figures 1 to 5 In some embodiments, there are multiple support groups, which are spaced apart along the axial direction of the buffer 310.

[0080] Specifically, this embodiment does not impose any limit on the number of support groups, and can be selectively set according to actual needs.

[0081] By setting multiple support groups, the ability of the buffer 310 to absorb and disperse the vibration of the piston rod 130 can be enhanced. When the piston rod 130 vibrates due to impact load, these support groups can absorb and disperse the vibration energy in segments. Since the support groups are distributed along the axial direction, the vibration of the second end 131 at different positions can be effectively buffered by the corresponding support groups, thereby improving the buffering efficiency and further reducing the high-frequency vibration of the piston rod 130.

[0082] Please refer to Figures 1 to 5 In some embodiments, the limiting structure 300 includes a limiting component 320, and the support 200 has a mounting cavity on the side opposite to the dust cover 120. The limiting component 320 is disposed within the mounting cavity, sleeved on the second end 131, and fixed relative to the second end 131. The inner circumferential side of the limiting component 320 contacts the second end 131, and the outer circumferential side of the limiting component 320 elastically contacts the cavity wall of the mounting cavity.

[0083] Specifically, when the piston rod 130 vibrates or displaces due to impact load, the inner circumferential side of the limiting component 320 can make close contact with the second end 131 of the piston rod 130, thereby absorbing the vibration of the piston rod 130. At the same time, since the outer circumferential side of the limiting component 320 is in elastic contact with the cavity wall of the mounting cavity, the limiting component 320 can absorb part of the vibration energy through elastic deformation, reduce the transmission of vibration, and thus reduce the noise generated by vibration.

[0084] Because the limiting component 320 is in elastic contact with the cavity wall of the mounting cavity, when the piston rod 130 is subjected to an impact load, the limiting component 320 can buffer the displacement of the piston rod 130 through elastic deformation, preventing the piston rod 130 from having a hard collision with the support 200 due to excessive displacement, thus extending the service life of the vibration damping mechanism.

[0085] Please refer to Figures 1 to 5 In some embodiments, the limiting component 320 includes a mounting plate 321 and an elastic member 322. The mounting plate 321 has a through hole, and a second end 131 passes through the through hole and contacts the hole wall. The hole wall forms the circumferential inner side of the limiting component 320. The elastic member 322 surrounds the circumferential outer side of the mounting plate 321, and the side of the elastic member 322 facing away from the mounting plate 321 forms the circumferential outer side of the limiting component 320.

[0086] Specifically, in this embodiment, both the elastic member 322 and the mounting plate 321 are disposed in the mounting cavity. The elastic member 322 has a mounting groove for mounting the mounting plate 321, and the mounting part is embedded in the mounting groove to engage with the elastic member 322.

[0087] The mounting plate 321 has a through hole, and the second end 131 passes through the through hole. When the piston rod 130 is subjected to impact vibration, the vibration energy can be transmitted to the elastic element 322 through the mounting plate 321, thereby causing the elastic element 322 to undergo elastic deformation and absorb the vibration energy, reducing the vibration amplitude of the piston rod 130. At the same time, when the piston rod 130 is displaced due to vibration, the elastic element 322 can absorb the displacement of the piston rod 130 through elastic deformation, thereby preventing the second end 131 of the piston rod 130 from rigidly colliding with the support 200.

[0088] In this embodiment, the elastic element 322 is made of polyurethane material. In other embodiments, the material and manufacturing process of the elastic element 322 can also be adapted to be selected. This embodiment does not impose any restrictions on this.

[0089] Please refer to Figures 1 to 5 In some embodiments, the electronically controlled vibration damping mechanism further includes a connector 400, and the mounting plate 321 is detachably connected to the second end 131 via the connector 400.

[0090] Specifically, in this embodiment, the connector 400 is used to fix the second end 131 and the connector 400 to ensure a stable connection between the mounting plate 321 and the second end 131, and to prevent the mounting plate 321 from disengaging from the second end 131 under vibration.

[0091] In this embodiment, the connector 400 is a nut, and the second end 131 is provided with an external thread. The connector 400 is screwed onto the second end 131 and abuts against the mounting plate 321. This allows for detachable installation while ensuring the stability of the connection between the second end 131 and the mounting plate 321, and preventing the mounting plate 321 from disengaging from the second end 131.

[0092] In other embodiments, the specific structure of the connector 400 can be adapted to actual needs, and this embodiment does not impose any restrictions on this.

[0093] Please refer to Figures 1 to 5 In some embodiments, the limiting structure 300 includes a buffer 310 and a limiting assembly 320. The buffer 310 is sleeved on the second end 131 and located between the support 200 and the dust cover 120. One end of the buffer 310 is connected to and fixed relative to the support 200, and the other end of the buffer 310 is fixed relative to the outer cylinder 110. At least a portion of the inner wall of the buffer 310 contacts the circumferential outer wall of the second end 131. The support 200 has a mounting cavity on the side opposite to the dust cover 120. The limiting assembly 320 is disposed in the mounting cavity, sleeved on the second end 131, and fixed relative to the second end 131. The circumferential inner side of the limiting assembly 320 contacts the second end 131, and the circumferential outer side of the limiting assembly 320 elastically contacts the cavity wall of the mounting cavity.

[0094] Specifically, the specific structures of the buffer 310 and the limiting component 320 have been described in the above embodiments and will not be repeated here.

[0095] By setting the buffer 310 and the limiting component 320, the vibration of the piston rod 130 and the dust cover 120 can be absorbed at the same time. At the same time, the rigid collision between the second end 131 and the bracket can be avoided, which extends the service life of the electronically controlled vibration damping mechanism, avoids noise, and improves the user experience.

[0096] Please refer to Figures 1 to 5 In some embodiments, the support 200 includes a sleeve portion 210, a first connecting portion 220, and a second connecting portion 230. The first connecting portion 220 and the second connecting portion 230 are arranged at a preset angle and connected to each other. The first connecting portion 220 and the second connecting portion 230 are located circumferentially in the sleeve portion 210. A second end 131 passes through the sleeve portion 210. The first connecting portion 220 and the second connecting portion 230 are connected to the vehicle body. The vehicle body has a connection area that connects to the first connecting portion 220 and the second connecting portion 230, and the preset angle matches the structure of the vehicle body in the connection area.

[0097] Specifically, in this embodiment, the support 200 includes a sleeve portion 210, a first connecting portion 220, and a second connecting portion 230. The sleeve portion 210 forms an installation cavity, and the limiting component 320 is disposed in the installation cavity. The second end 131 passes through the sleeve portion to be fixed and limited by the support 200.

[0098] The first connecting part 220 and the second connecting part 230 are set at a preset angle and connected to each other. The preset angle matches the structure of the vehicle body in the connecting area, so that the support 200 matches the structure of the vehicle body in the connecting area, ensuring the tightness and stability of the connection between the support 200 and the vehicle body.

[0099] In this embodiment, there are two first connecting parts 220 and two second connecting parts 230. The two first connecting parts 220 are respectively disposed on both sides of the sleeve part 210. Corresponding to the first connecting parts 220, the two second connecting parts 230 are also respectively disposed on both sides of the sleeve part 210 to connect with the first connecting parts 220. This makes the support 200 form a symmetrical structure, avoiding the need for operators to distinguish the directions of the first connecting parts 220 and the second connecting parts 230 during installation, reducing the installation difficulty and improving the installation efficiency.

[0100] In this embodiment, the first connecting part 220 has two first mounting holes 221, and the second connecting part 230 has two second mounting holes 231. The four fasteners correspond one-to-one with the first mounting holes 221 and the second mounting holes 231, so as to connect the first connecting part 220 to the vehicle body and the second connecting part 230 to the vehicle body, thereby further ensuring the stability of the connection between the support 200 and the vehicle body.

[0101] In this embodiment, there are no restrictions on the number or arrangement of the first mounting hole 221 and the second mounting hole 231. The selection can be made according to actual needs.

[0102] In this embodiment, the support 200 further includes at least one reinforcing part 240, the two ends of which are connected to the first connecting part 220 and the second connecting part 230 respectively, thereby enhancing the structural strength and stability of the support 200 and preventing the support 200 from deforming or being damaged under external force.

[0103] It should be noted that this embodiment does not impose any limitation on the number of reinforcing parts 240, and can make an adaptive selection according to actual needs.

[0104] In some embodiments, the sleeve portion 210 further has an end cap to shield the second end 131 and the through hole, thereby causing external dust or impurities to adhere to the second end 131.

[0105] Secondly, this embodiment provides a vehicle, including a body and an electronically controlled damping mechanism as described in any one of the first aspects, wherein the support 200 of the electronically controlled damping mechanism is connected to the body.

[0106] The electronically controlled vibration damping mechanism has been described in the above embodiments and will not be repeated here.

[0107] The vehicle provided in this embodiment includes a vehicle body and an electronically controlled vibration damping mechanism as described in any one of the first aspects. The support 200 of the electronically controlled vibration damping mechanism is connected to the vehicle body. The electronically controlled vibration damping mechanism includes a damper 100, a support 200, and a limiting structure 300. The damper 100 includes an outer cylinder 110, a dust cover 120, and a piston rod 130. The outer cylinder 110 is movable relative to the dust cover 120 along a first direction x. The first end of the piston rod 130 passes through the dust cover 120 and is disposed inside the outer cylinder 110, and is fixed relative to the dust cover 120. The second end 131 of the piston rod 130 is located outside the dust cover 120. The support 200 is sleeved on the second end 131 and fixed relative to the second end 131, and the support 200 is configured to connect to the vehicle body. The limiting structure 300 is also fitted onto the second end 131 and fixed relative to the support 200. The limiting structure 300 is used to limit the displacement of the piston rod 130, thereby suppressing the high-frequency vibration of the piston rod 130, avoiding noise caused by the vibration of the piston rod 130, and improving the user experience.
