Description

Technical Field

[0001] This invention relates to the field of vibration isolation technology in transportation, and more specifically to a suspended vibration isolation system. Background Technology

[0002] In conventional suspended vibration isolation systems, the object to be isolated is typically placed within a frame, and then vibration is isolated by structures such as springs and spring sheets positioned between the object and the frame. Because only elastic elements are used to attenuate vibrations, the system's ability to attenuate low-frequency vibrations is limited, thus restricting the application of suspended vibration isolation systems.

[0003] An inertial container is a novel mechanical element with advantages such as "passing high frequencies and blocking low frequencies" and "achieving large inertia with relatively small mass." Due to these advantages, inertial containers have broad application prospects in the field of vibration isolation. Introducing an inertial container into a suspended vibration isolation system can significantly improve the system's isolation effect on low-frequency vibrations, thus expanding the application range of suspended vibration isolation systems.

[0004] However, the inertial container itself cannot generate elastic force, so it cannot bear load or generate damping force. Therefore, it cannot be used alone in scenarios where load bearing is required, and it needs to be combined with elastic elements and dampers for coordinated use. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problems of the inertial container being unable to bear load and having small damping in the prior art. The inertial capacitive structure inside the inertial container is connected in series with the damper, and then connected in parallel with the elastic device to design and implement a new type of vibration isolation mechanism. The new vibration isolation mechanism is set obliquely, thereby providing a suspended vibration isolation system.

[0006] To address the aforementioned technical problems, this invention provides a suspended vibration isolation system, comprising:

[0007] An outer frame is connected to an inner frame by several diagonally braced vibration isolation mechanisms, and the inner frame is suitable for housing objects to be isolated.

[0008] The vibration isolation mechanism includes: an inertial container, the interior of which has an inertial capacitive structure and a damper arranged in series, and the exterior of which has an elastic element connected in parallel.

[0009] Optionally, the elastic element includes: a first connecting frame and a second connecting frame spaced apart, the first connecting frame and the second connecting frame being connected by a spring.

[0010] Optionally, one end of the damper extends out of the housing of the inertia container and is connected to the first connecting frame of the elastic element, and one end of the inertia capacitive structure extends out of the housing of the inertia container and is connected to the second connecting frame of the elastic element.

[0011] Optionally, the spring has bolts at both ends, and the first connecting bracket and the second connecting bracket have screw holes at their adjacent ends for screwing in the bolts.

[0012] Optionally, both the first connecting frame and the second connecting frame are L-shaped frames.

[0013] Optionally, the inner frame is a rectangular frame, and each edge of the inner frame perpendicular to the vibration isolation mechanism has at least one set of mounting holes. The vibration isolation mechanism is rotatably connected to the mounting holes of the inner frame via a connecting shaft.

[0014] Optionally, the connecting shaft is an optical shaft, and both ends of the optical shaft have annular grooves for mounting shaft retaining rings.

[0015] Optionally, the outer frame has a groove for inserting the vibration isolation mechanism, and the vibration isolation mechanism is rotatably connected to the groove via a connecting shaft.

[0016] Optionally, the groove is a strip-shaped groove arranged circumferentially along the outer frame, and the strip-shaped groove has a plurality of mounting holes spaced apart for mounting the connecting shaft.

[0017] Optionally, the bottom of the outer frame has a support extending outward in a horizontal direction.

[0018] Optionally, the inertia capacity structure includes: a large gear and a small gear that mesh with each other, the large gear being mounted on a first rotating shaft and the small gear being mounted on a second rotating shaft, the first rotating shaft and the second rotating shaft being detachably mounted on the housing of the inertia container;

[0019] A transmission gear is also installed on the first rotating shaft, and a transmission rack is slidably disposed on the shell of the inertial container. The two ends of the transmission rack extend out of the shell in two opposite directions, and the transmission gear meshes with the transmission rack for transmission.

[0020] A flywheel is also mounted on the second shaft, and the rotation of the flywheel is used to provide inertial force.

[0021] Optionally, two sets of rotating bearings are detachably installed on the outer wall of the inertial container shell, with the first rotating shaft and the second rotating shaft respectively installed inside the rotating bearings.

[0022] Optionally, the first and second rotating shafts are optical shafts, and the rotating bearing has an inner sleeve for inserting the end of the optical shaft. The inner sleeve has a threaded hole, and a bolt is screwed into the threaded hole to form a fixed connection between the optical shaft and the inner sleeve.

[0023] Optionally, the large gear, small gear, transmission gear, and flywheel are each provided with a boss along the axial direction. The boss is provided with a threaded hole. Bolts are screwed into the threaded holes to fix the large gear and the transmission gear to the first rotating shaft, and to fix the small gear and the flywheel to the second rotating shaft.

[0024] Optionally, both ends of the transmission rack are connected to the housing via linear bearings, and the linear bearings are detachably mounted on the housing.

[0025] The technical solution of this invention has the following advantages:

[0026] The suspended vibration isolation system provided by this invention employs a parallel combination of an elastic element and an inertial container, with a damper added inside the inertial container. The damper and the inertial capacitive structure form a series relationship. The elastic element is responsible for load bearing, the inertial capacitive structure is responsible for generating inertial force, and the damper is responsible for generating damping force. This solves the load bearing problem and increases the damping force. The inertial capacitive structure is a novel mechanical element with advantages such as "passing high frequencies and blocking low frequencies" and "achieving large inertia with relatively small mass." Due to these advantages, the inertial capacitive structure has broad application prospects in the field of vibration isolation. Introducing the inertial capacitive structure into the suspended vibration isolation system can significantly improve the vibration isolation effect on low-frequency vibrations, expanding the application range of the suspended vibration isolation system.

[0027] Furthermore, in the suspended vibration isolation system provided by this invention, the vibration isolation mechanism is detachably connected to the inner and outer frames, and all components inside the vibration isolation mechanism are detachable. This makes the entire suspended vibration isolation system provided by this invention detachable and assembleable, facilitating the repair and replacement of damaged parts. Multiple mounting holes on the outer frame allow adjustment of the angle between the vibration isolation mechanism and the horizontal direction to meet the needs of different application environments. The transmission rack and damper are arranged in parallel, achieving a series structure and saving axial length. Moreover, because the damper and transmission rack are not concentric, after cooperating with the first and second connecting frames, the entire structure cannot rotate around the same axis, increasing the stability of the structure.

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] The suspended vibration isolation system provided in this embodiment is used for vibration isolation when transporting goods.

[0041] like Figure 1 The diagram illustrates a specific implementation of the suspended vibration isolation system provided in this embodiment. It includes an outer frame 1 connected to an inner frame 10 via several diagonally braced vibration isolation mechanisms. The inner frame 10 is suitable for housing the object to be isolated. The vibration isolation mechanism includes an inertial container 2, which has an inertial capacitive structure and a damper 3 arranged in series inside. An elastic element 4 is connected in parallel outside the inertial container 2. It should be noted that the inertial container 2 in this embodiment includes an inertial capacitive structure and a damper 3 inside its shell, arranged in series within the shell. In other words, the inertial container 2 in this embodiment refers to a novel inertial container 2 formed by combining an inertial capacitive structure and a damper 3 arranged in series inside its shell. The inertial container 2 is connected in parallel with the elastic element 4. During use, the actions of the inertial container 2 and the elastic element 4 influence each other, i.e., they synchronously reduce vibration. When the elastic element 4 resets, the inertial container 2 also synchronously resets. Furthermore, inside the inertia container 2, the inertia capacitive structure and the damper 3 experience the same force, but their amplitudes of motion may differ; one may have a larger amplitude of motion, while the other may have a smaller amplitude. Specifically, the elastic element 4 can be a spring 9 or a sheet spring, etc.

[0042] like Figure 2 As shown, in the suspended vibration isolation system provided in this embodiment, the elastic element 4 includes: a first connecting frame 7 and a second connecting frame 8 spaced apart, and a spring 9 is provided between the first connecting frame 7 and the second connecting frame 8. When the first connecting frame 7 and the second connecting frame 8 are pulled away from each other by tension, the spring 9 is used to provide an elastic force to bring them closer together. When the first connecting frame 7 and the second connecting frame 8 are compressed and brought closer together, the spring 9 is used to provide an elastic force to pull them away from each other.

[0043] like Figure 2As shown, one end of the damper 3 extends out of the housing of the inertia container 2 and is used to connect with the first connecting frame 7 of the elastic device 4. The other end of the inertia container structure extends out of the housing of the inertia container 2 in the opposite direction to the first connecting end 5 and is used to connect with the second connecting frame 8 of the elastic device 4. With this configuration, in use, the inertial force and damping force provided by the inertia container 2 are used for vibration reduction, while the elastic force provided by the elastic device 4 is used for load bearing, thus enabling the vibration isolation system to adapt to a wider range of application environments.

[0044] like Figure 2 As shown, the end of the first connecting frame 7 away from the second connecting frame 8 has a first connecting end 5, and the end of the second connecting frame 8 away from the first connecting frame 7 has a second connecting end 6. When the vibration isolation mechanism is connected between the outer frame 1 and the inner frame 10, one end of the vibration isolation mechanism is connected to the inner frame 10 via the first connecting end 5, and the other end is connected to the outer frame 1 via the second connecting end 6; of course, it can also be the other way around, with the second connecting end 6 connecting to the inner frame 10 and the first connecting end 5 connecting to the outer frame 1.

[0045] In this embodiment, the spring 9 has bolts at both ends, and the ends of the first connecting frame 7 and the second connecting frame 8 that are close to each other have screw holes for screwing in the bolts. That is, one end of the spring 9 is installed into the first connecting frame 7 by screwing, and the other end of the spring 9 is installed into the second connecting frame 8. This arrangement improves the stability of the spring 9 within the first connecting frame 7 and the second connecting frame 8. Of course, this is not limiting; in some embodiments, the spring 9 can also be connected to the first connecting frame 7 and the second connecting frame 8 using other structures.

[0046] like Figure 2 As shown, in the suspended vibration isolation system provided in this embodiment, both the first connecting frame 7 and the second connecting frame 8 are L-shaped frames. In this embodiment, the shell of the inertia container 2 has a rectangular shape. Therefore, to connect the elastic element 4 and the inertia container 2 in parallel and as a single unit, it is necessary to connect the two connecting ends of the elastic element 4 and the inertia container 2. The L-shaped design of the first connecting frame 7 and the second connecting frame 8 allows for the parallel arrangement of the elastic element 4 and the inertia container 2, thereby improving the performance of the elastic element 4 and the inertia container 2 after parallel connection.

[0047] like Figure 1As shown, the suspended vibration isolation system provided in this embodiment further includes: an inner frame 10, which is disposed in the middle of the outer frame 1. The inner frame 10 is connected to the outer frame 1 through four spaced vibration isolation mechanisms. The inner frame 10 is suitable for placing the object to be isolated. With this arrangement, when the outer surface of the object to be isolated has no connecting structure, vibration isolation can be achieved by placing the object to be isolated within the inner frame 10. The number of vibration isolation mechanisms is not limited to four; it can also be three or more.

[0048] like Figure 1 As shown, in the suspended vibration isolation system provided in this embodiment, the inner frame 10 is a rectangular frame, and the inner frame 10 is connected to the outer frame 1 through the vibration isolation mechanism. Since the outer frame 1 is generally a rectangular structure in actual use, setting the inner frame 10 to a rectangular frame makes it easier to connect the inner frame 10 and the outer frame 1; however, this is not limiting, and the inner frame 10 can also be other structures, such as a sphere.

[0049] like Figure 1 As shown, in the suspended vibration isolation system provided in this embodiment, the inner frame 10 has a set of mounting holes on its edges perpendicular to the vibration isolation mechanism. The vibration isolation mechanism is rotatably connected to the mounting holes of the inner frame 10 via a connecting shaft. Specifically, as shown... Figure 2 As shown, in this embodiment, the first connecting end 5 and the second connecting end 6 of the inertial container 2 are respectively provided with through holes, which are suitable for inserting a connecting shaft. The mounting holes of the inner frame 10 are correspondingly provided with the through holes. After aligning the first connecting end 5 or the second connecting end 6 of the inertial container 2 with the mounting holes of the inner frame 10, the connecting shaft passes through the mounting holes and the through holes, thereby realizing the rotational connection between the inner frame 10 and the inertial container 2. The connecting shaft can be an optical shaft with annular grooves at both ends for mounting shaft retaining rings. By rotating the vibration isolation mechanism with the inner frame 10, the vibration isolation mechanism can always maintain its connection with the inner frame 10 during vibration. Alternatively, as an alternative embodiment, the vibration isolation mechanism and the inner frame 10 can also be connected using other structures, such as a ball joint.

[0050] like Figure 1As shown, in the suspended vibration isolation system provided in this embodiment, the outer frame 1 has a groove 11 for inserting the vibration isolation mechanism, and the vibration isolation mechanism is rotatably connected within the groove 11 via a connecting shaft. Similarly, in the vibration isolation mechanism, the second connecting end 6 of the inertia container 2 is provided with a through hole; when connecting the vibration isolation mechanism to the outer frame 1, the second connecting end 6 can be inserted into the groove 11 of the outer frame 1, and then the connecting shaft passes through the through hole of the second connecting end 6 and the mounting hole on the groove 11, thereby achieving a rotatable connection between the vibration isolation mechanism and the outer frame 1. With this configuration, the vibration isolation mechanism can always maintain its connection with the outer frame 1 during vibration. Alternatively, as an alternative implementation, the vibration isolation mechanism and the outer frame 1 can also be connected using other structures, such as a ball joint connection.

[0051] like Figure 1 As shown, in the suspended vibration isolation system provided in this embodiment, the groove 11 is a strip-shaped groove arranged circumferentially along the outer frame 1, and the strip-shaped groove has a plurality of mounting holes spaced apart for mounting the connecting shaft. This arrangement allows the mounting position of the vibration isolation mechanism on the outer frame 1 to be adjusted as needed, thereby changing the mounting angle of the vibration isolation mechanism to adapt to different vibration isolation environments. Alternatively, as an alternative implementation, the strip-shaped groove may also have only one mounting hole.

[0052] like Figure 1 , Figure 5 As shown, in the suspended vibration isolation system provided in this embodiment, the vibration isolation mechanism is arranged obliquely. When arranged obliquely, its vibration isolation performance is better than that of a vertical arrangement. The vibration isolation performance can be significantly affected by adjusting the angle φ0 between the vibration isolation mechanism and the horizontal direction. Decreasing the angle φ0 in the AH direction and increasing it in the AD direction will decrease the angle φ0, and vice versa. Studies have shown that the smaller the angle φ0, the better the vibration isolation performance. This structural design allows the angle φ0 to be as small as possible. Furthermore, because the object M to be isolated is protected by vibration isolation mechanisms at both the top and bottom, even with a reduced angle φ0, the entire vibration isolation system can still maintain stable vibration isolation without instability.

[0053] The suspended vibration isolation system provided in this embodiment can provide buffer protection for the object M to be isolated in all directions. Furthermore, due to the presence of the outer frame ADGH, the entire vibration isolation system can be wrapped into a whole. This whole can be used independently, for example, it can be made into a box, or it can be installed on the ground for fixed use, such as a shelf with vibration isolation function.

[0054] like Figure 1As shown, in the suspended vibration isolation system provided in this embodiment, the bottom of the outer frame 1 has a bracket 12 extending outward in the horizontal direction. The bracket 12 improves the stability of the outer frame 1, thereby ensuring the overall stability of the system. Alternatively, the bracket 12 can be omitted, and other structures can be used to stabilize the outer frame 1.

[0055] like Figure 3 , Figure 4 As shown, in the suspended vibration isolation system provided in this embodiment, the inertial capacitance structure includes a large gear 15 and a small gear 16 that mesh and drive each other. The large gear 15 is mounted on a first rotating shaft 13, and the small gear 16 is mounted on a second rotating shaft 14. A transmission gear 17 is also mounted on the first rotating shaft 13, and the transmission gear 17 meshes with a transmission rack 19. A flywheel 18 is also mounted on the second rotating shaft 14, and the flywheel 18 provides inertial force. The two ends of the transmission rack 19 are slidably connected to the housing of the inertial container 2 through linear bearings, meaning that the transmission rack 19 can slide along its own axial direction. When subjected to external force, the transmission rack 19 and the damper 3 move along their own axes. The transmission rack 19 drives the transmission gear 17 to rotate, the transmission gear 17 drives the first rotating shaft 13 to rotate, the large gear 15 rotates synchronously on the first rotating shaft 13, the large gear 15 drives the small gear 16 to rotate, the small gear 16 drives the second rotating shaft 14 to rotate, thereby causing the flywheel 18 on the second rotating shaft 14 to rotate to provide inertial force.

[0056] like Figure 2-4 As shown, in the suspended vibration isolation system provided in this embodiment, two sets of rotating bearings are detachably installed on the outer wall of the inertia container 2. The first rotating shaft 13 and the second rotating shaft 14 are respectively installed in the rotating bearings. Specifically, one end of the transmission rack 19 extends out of the shell of the inertia container 2 and is provided with a second connecting end 6. The second connecting end 6 is used to connect with the outside world. When subjected to external force, the transmission rack 19 is driven to move along its own axis. The first rotating shaft 13 and the second rotating shaft 14 are optical shafts. The rotating bearing has an inner sleeve for inserting the end of the optical shaft. The inner sleeve has a threaded hole. A bolt is screwed into the threaded hole to form a fixed connection between the optical shaft and the inner sleeve. The large gear 15, small gear 16, transmission gear 17 and flywheel 18 are respectively provided with bosses along the axial direction. The bosses are provided with threaded holes. Bolts are screwed into the threaded holes to fix the large gear 15 and the transmission gear 17 to the first rotating shaft 13, and to fix the small gear 16 and the flywheel 18 to the second rotating shaft 14.

[0057] It should be noted that in this embodiment, the diameter of the transmission gear 17 is approximately the same as the diameter of the pinion 16. This arrangement allows the pinion 16 to rotate more revolutions when the first shaft 13 rotates a smaller number of revolutions, via the large gear 15, thus causing the flywheel 18 to rotate faster to provide inertial force. Furthermore, in this embodiment, the transmission rack 19 is a cylindrical rack, meaning a rack structure is formed on one side of the cylinder. This design improves the strength of the transmission rack 19 when it engages with the gear, enhancing the robustness of the rack structure. Additionally, both ends of the transmission rack 19 extend outside the housing of the inertia container 2. One end connects to an external load-bearing component, while the other end has a stop 20 to prevent excessive axial movement of the transmission rack 19, ensuring the safety of the vibration isolation system. Once the entire vibration isolation system is assembled, the cylindrical rack cannot rotate within the linear bearing.

[0058] Additionally, it should be noted that in this embodiment, the damper 3 is a hydraulic damper 3, comprising a hydraulic pipe and a moving rod. The end of the hydraulic pipe has a protruding threaded structure, and the head of the moving rod also has threads. The hydraulic pipe is fixedly connected to the housing of the inertial container 2 through the threaded structure. The threaded hole is on the housing, and the other end of the hydraulic pipe passes through a circular hole at the front of the housing. The diameter of the circular hole is basically the same as, but slightly larger than, the diameter of the hydraulic pipe to ensure that the hydraulic pipe can pass through the circular hole. The threads of the moving rod are used to connect the first connecting frame 7 of the elastic device 4 and adapters such as Y-type heads.

[0059] Under impact excitation, the suspended vibration isolation system designed in this application exhibits a faster attenuation rate and a smaller maximum impact response acceleration. Under random excitation, the energy distribution of the suspended vibration isolation system designed in this invention at all frequencies is smaller than that of a general suspended vibration isolation system and a suspended vibration isolation system with an oblique damper.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
