Description

Technical Field

[0001] The present invention relates to the technical field of dampers, and in particular to an adaptive damper and a device based on the damper. Background Art

[0002] Friction dampers are one of the simpler dampers that are widely studied at home and abroad. Since the late 1970s, in order to meet the energy consumption and vibration reduction requirements of different building structures, engineering researchers have developed a variety of different forms of friction dampers. They are not only used in new passive control structures in many countries, but also in the vibration reinforcement of structures and improving the vibration resistance of wooden structures.

[0003] Friction dampers are a type of device that utilizes the friction force generated by the relative motion of friction surfaces under pressure to convert external input energy into other forms of energy, thereby changing the state of motion of an object. Traditional friction dampers give the friction surfaces a certain amount of pre-pressure through methods such as high-strength bolts and interference contact. When impact or vibration occurs, the friction surfaces overcome sliding friction and produce relative motion, thereby achieving the purpose of energy dissipation. However, due to the fixed pressure between the friction surfaces, the friction damper's friction adjustment has a constant buffering or adjustment force for the impact and vibration size, which cannot meet current actual needs.

[0004] Patent document CN209130098U discloses a novel spring damper and a socket cover structure containing the spring damper, wherein the novel spring damper comprises a damping frame and a spring, wherein the damping frame comprises a limiting plate and an extension portion which is arranged in the middle of one end surface of the limiting plate and protrudes outward, wherein one end of the spring is sleeved on the outer periphery of the extension portion, and the outer diameter of the spring is smaller than the size of the limiting plate; the axial length of the spring in a non-compressed state is greater than the length of the extension portion; a through hole which penetrates the damping frame front and back is arranged at the center of the extension portion in the axial direction, but when this design is subjected to a strong impact, the buffer structure is single and the impact resistance is poor.

[0069] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0070] The present invention provides an adaptive damper, such as Figure 1 As shown, it includes a device housing 1, a functional rod 2, a first elastic component 3, a second elastic component 4, a first damping adjustment component 5 and a second damping adjustment component 6. A motion channel 7 is provided in the device housing 1. The functional rod 2 passes through the motion channel 7 and is divided from the device housing 1 by the second elastic component 4 installed in the device housing 1 to form a first accommodating space 8 and a second accommodating space 9. The first damping adjustment component 5 and the second damping adjustment component 6 are respectively installed in the first accommodating space 8 and the second accommodating space 9. The second elastic component 4 is installed between the first damping adjustment component 5 and the second damping adjustment component 6. The first elastic component 3 includes a first elastomer 10 and a second elastomer 11. The first elastomer 10 is installed at one end of the first damping adjustment component 5 away from the second elastic component 4, and the second elastomer 11 is installed at one end of the second damping adjustment component 6 away from the second elastic component 4.

[0071] Specifically, Figure 2As shown, in a preferred example, the first damping adjustment component 5 includes a first support frame 15 and a first rolling body 16, the first rolling body 16 is installed on the first support frame 15 and the first support frame 15 can drive the first rolling body 16 to move along the axial direction of the functional rod 2 under the drive of external force, and the second damping adjustment component 6 includes a second support frame 17 and a second rolling body 18, the second rolling body 18 is installed on the second support frame 17 and the second support frame 17 can drive the second rolling body 18 to move along the axial direction of the functional rod 2 under the drive of external force. In a variation, the first damping adjustment component 5 and the second damping adjustment component 6 are both translational bodies, which can move along the axial direction of the functional rod 2 under the drive of external force. When the first damping adjustment component 5 and the second damping adjustment component 6 are both translational bodies, the external structures of the first damping adjustment component 5 and the second damping adjustment component 6 can be matched with the first accommodating space 8 and the second accommodating space 9, respectively. For example, when the translational body moves in the first accommodating space 8 under the extrusion of the first elastic body 10, the extrusion force between the translational body and the functional rod 2 becomes smaller, and then the friction force becomes smaller, thereby realizing the adjustment of the motion damping of the functional rod 2.

[0072] Specifically, in practical applications, the structure of the translational body can be reasonably selected according to the actual application scenario. For example, the translational body adopts a wedge-shaped block, and the corresponding first accommodating space 8 and the second accommodating space 9 also adopt a structure matching the translational body, so that the friction force between the translational body and the functional rod 2 can be adjusted after a small movement of the translational body; in addition, the number of translational bodies can be set one in the first accommodating space 8 and the second accommodating space 9 respectively, or multiple translational bodies can be set respectively. When multiple translational bodies are set, the multiple translational bodies can be arranged in series on one side of the functional rod 2, or they can be arranged uniformly or non-uniformly along the circumference of the functional rod 2.

[0073] Specifically, Figure 2As shown, the damping device in the present invention includes an intermediate adjustment mode and / or an end adjustment mode, wherein: in the end adjustment mode, the first elastic body 10 squeezes the first damping adjustment component 5 under the drive of external force, thereby causing the first support frame 15 to drive the first rolling body 16 to move close to the second elastic component 4 and then drive the second elastic component 4 to move and elastically deform. Since the first accommodating space 8 is a conical space, a wedge-shaped space or a space with a gradually changing volume, the squeezing force between the first rolling body 16 and the functional rod 2 becomes smaller, and the friction force between the functional rod 2 and the first rolling body 16 becomes smaller. Therefore, at this time, the functional rod 2 can move relative to the device housing 1. When the force of the first elastic body 10 squeezing the first damping adjustment component 5 is released or reduced, under the action of the rebound force of the second elastic component 4, the deformed part of the second elastic component 4 returns to its original shape. Therefore, the second elastic component 4 drives the first support frame 15 to drive the first rolling body 16 to move close to the first elastic body 10. At this time, the friction between the functional rod 2 and the first rolling body 16 becomes larger, so the friction force of the functional rod 2 relative to the device housing 1 increases. Therefore, by adjusting the size of the squeezing force between the first rolling body 16 and the functional rod 2, the friction between the first rolling body 16 and the functional rod 2 can be adjusted to achieve the adjustment of the device damping.

[0074] Furthermore, if Figure 2 As shown, the second elastomer 11 can drive the second damping adjustment component 6 to move close to the second elastic component 4 and thereby cause the second elastic component 4 to undergo elastic deformation. Based on the same principle as the first damping adjustment component 5, the friction force between the first rolling body 16 and the functional rod 2 can also be adjusted, thereby meeting the damping adjustment requirements of the device.

[0075] Furthermore, the first elastic body 10 , the second elastic body 11 , the third elastic body 12 , and the fourth elastic body 13 may be springs or elastic rubbers according to actual application scenarios.

[0076] Specifically, Figure 2As shown, in the intermediate adjustment mode, the second elastic component 4 includes a third elastic body 12, a fourth elastic body 13 and an adjustment handle 14, and an adjustment gap perpendicular to the radial direction of the function rod 2 is arranged between the third elastic body 12 and the fourth elastic body 13. Under the drive of external force, one end of the adjustment handle 14 can move close to or away from the function rod 2 in the adjustment gap and drive the first damping adjustment component 5 and the second damping adjustment component 6 to move close to or away from the first elastic body 10 and the second elastic body 11 respectively. In a preferred example, an adjustment handle through hole is arranged on the device housing 1, one end of the adjustment handle 14 extends into the adjustment gap, and the other end of the adjustment handle 14 is an operating end. By operating the operating end, the distance between the adjustment handle 14 and the function rod 2 can be adjusted, and then the third elastic body 12 and the fourth elastic body 13 can be synchronously applied with a thrust. At this time, the first support frame 15 and the second support frame 17 respectively move in the direction away from the adjustment handle 14 or have a tendency to move in the direction away from the adjustment handle 14, and then the motion damping of the function rod 2 can also be adjusted.

[0077] Furthermore, if Figure 1 As shown, the first damping adjustment component 5 in the present invention can be set by one, or multiple components can be set in sequence along the axial direction of the functional rod 2, and both can implement the present invention. In practical applications, it should be reasonably designed according to the specific application scenario to meet the needs of practical applications. Based on the same principle, the number of second damping adjustment components 6 can also be designed according to the specific application scenario.

[0078] Specifically, Figure 1 As shown, the number of the first rolling bodies 16 is one or more, the number of the second rolling bodies 18 is one or more, the first rolling bodies 16 and the second rolling bodies 18 are both rolling elements. In a preferred example, the rolling elements are balls, such as steel balls. In a variation, the rolling elements are cylinders, such as steel cylinders.

[0079] Further, when there are multiple rolling elements, there are multiple arrangements, for example, multiple rolling elements are arranged in sequence according to their volume along the length direction of the functional rod 2 to form a rolling element group, and multiple rolling elements can synchronously apply force to the functional rod 2. The number of the rolling element group is one or more. When the number of the rolling element group is one, the rolling element group is installed on one side of the functional rod 2; when there are multiple rolling element groups, the multiple rolling element groups are arranged uniformly or non-uniformly along the circumference of the functional rod 2 to form multiple layers of rolling elements to adjust the motion friction of the functional rod 2 along the circumference, thereby adjusting the motion damping of the functional rod 2. For another example, multiple rolling elements are arranged uniformly or non-uniformly along the circumference of the functional rod 2 to form a layer of rolling element group.

[0080] Specifically, Figure 2As shown, the intermediate adjustment mode and the end adjustment mode can be adjusted manually or non-manually. When manual adjustment is adopted in the end adjustment mode, the present invention also includes a manual adjustment wheel 30, one end of which is provided with an external thread, and the motion channel 7 of the device housing 1 is provided with an internal thread. The manual adjustment wheel 30 is matched and mounted on the internal thread of the motion channel 7. When the manual adjustment wheel 30 is rotated, the manual adjustment wheel 30 can move closer to or away from the first elastomer 10 and / or closer to or away from the second elastomer 11, thereby realizing the adjustment of the motion damping of the functional rod 2.

[0081] Furthermore, when manual adjustment is adopted in the intermediate adjustment mode, such as Figure 2 As shown, by manually adjusting the operating end of the adjusting handle 14 , the movement distance between the adjusting handle 14 and the functional rod 2 is adjusted, thereby adjusting the movement damping of the functional rod 2 .

[0082] Specifically, when the intermediate adjustment mode and the end adjustment mode are adjusted by non-manual means, a variety of driving modes can be used, such as motor adjustment. Figure 3 As shown, the motor drives the manual adjustment wheel 30 to move in the axial direction of the function rod 2. When the motor rotates, the motor output shaft can drive the manual adjustment wheel 30 to move in the axial direction of the function rod 2 to adjust the motion damping of the function rod 2, or the motor drives the adjustment handle 14 to move in the radial direction of the function rod 2, as shown in FIG. Figure 4 As shown, the motion damping of the functional rod 2 is adjusted; for example, smart material driving is adopted to realize the driving of the first elastic body 10, the second elastic body 11 or the driving of the adjustment handle 14 through the properties of the smart material, for example, shape memory alloy is adopted to control the driving through temperature changes; for another example, magnetostrictive material is adopted to realize the driving; for another example, air pressure or hydraulic driving is adopted to realize the driving force through a cylinder or an oil cylinder; for another example, magnetic force driving is adopted to realize the driving through the magnetic force of a permanent magnet or an electromagnetic coil; phase change material driving can also be adopted to realize the volume change caused by temperature change of the phase change material and then realize the displacement driving.

[0083] Specifically, Figure 5As shown, the second elastic component 4 includes a third elastomer 12 and a fourth elastomer 13, a third accommodating space 19 is formed between the functional rod 2 and the device housing 1, and the third accommodating space 19 is arranged between the third elastomer 12 and the fourth elastomer 13, the functional rod 2 is circumferentially provided with a first blocking body 20 and a second blocking body 21 and both extend into the third accommodating space 19, the first blocking body 20 and the second blocking body 21 are arranged at intervals along the length direction of the functional rod 2, wherein the first blocking body 20 is connected to the device housing 1 through a first spring 22 arranged on one side of the third accommodating space 19, and the second blocking body 21 is connected to the device housing 1 through a second spring 23 arranged on the other side of the third accommodating space 19.

[0084] Specifically, Figure 5 As shown, the third accommodating space 19 is filled with fluid 24, and gaps are respectively arranged between the first blocking body 20 and the second blocking body 21 and the device housing 1. The first blocking body 20 and the second blocking body 21 divide the third accommodating space 19 into a first chamber 25, a second chamber 26, and a third chamber 27 in turn. The first chamber 25 and the second chamber 26, the second chamber 26 and the third chamber 27 are respectively connected through the gaps. In a preferred example, through holes are respectively arranged on the first blocking body 20 and the second blocking body 21. The through holes on the first blocking body 20 connect the first chamber 25 and the second chamber 26, and the through holes on the second blocking body 21 connect the second chamber 26 and the third chamber 27.

[0085] The present invention also provides a seal, which is arranged on both sides of the third accommodating space 19 and installed between the device housing 1 and the functional rod 2, to play a sealing role, and prevent the fluid in the third accommodating space 19 from moving to other parts through the gap between the device housing 1 and the functional rod 2 to cause pollution. The seal can adopt a variety of structural forms to meet the needs of different application scenarios, such as using an O-ring.

[0086] Furthermore, if Figure 5 As shown, the third elastomer 12 and the fourth elastomer 13 can also play a sealing role.

[0087] In the present invention, a third accommodating space 19 is provided and a plurality of blocking bodies are provided in the third accommodating space. When the functional rod 2 drives the blocking bodies to move, the fluids provided in the respective chambers flow from between the respective chambers through the through holes or gaps due to the squeezing of the blocking bodies, thereby realizing damping adjustment during the movement of the functional rod 2. The entire device forms a composite damping system, making the movement of the functional rod 2 more stable, and being able to activate the vibration reduction effect in some specific occasions.

[0088] Specifically, Figure 5As shown, in a preferred example, the functional rod 2 is further provided with a third blocking body 28, which is arranged in the second chamber 26 and divides the second chamber 26 into two spaces, wherein the two spaces are connected through the through hole on the third blocking body 28 and / or the gap between the third blocking body 28 and the device housing 1. It should be pointed out that the third blocking body 28 can be designed according to actual conditions, and can be designed as one or more to obtain greater vibration reduction and buffering effects.

[0089] Specifically, Figure 6 As shown, the device housing 1 is also provided with an electromagnetic coil 29, and the fluid is a magnetorheological fluid. When the electromagnetic coil 29 is energized, a magnetic field of different strengths can be generated according to the magnitude of the energized current, thereby enabling the fluid to be in a state of liquid or solid-liquid coexistence, thereby changing the resistance of the blocking body when following the movement of the functional rod 2, thereby adjusting the damping of the movement of the functional rod 2. In a preferred example, as Figure 7 As shown, the electromagnetic coil 29 adopts multiple small coils 32, and the small coils 32 are safely installed on the device housing 1. The local magnetic field formed by the small coils 32 can also realize the adjustment of the coexistence of the magnetorheological fluid liquid phase or solid-liquid phase. By changing the current, active control of variable damping is achieved, which can be suitable for more application scenarios.

[0090] The present invention also provides a damper-based device, which in a preferred embodiment is a new spring assembly, such as Figure 8As shown, it includes an upper support member 33, a lower support member 34 and a third spring 35, the third spring 35 is sleeved on the outside of the adaptive damper and the upper end of the third spring 35 is connected to the upper support member 33, the lower end of the third spring 35 is connected to the lower support member 34, one end of the functional rod 2 in the adaptive damper is fixedly connected to the upper support member 33, the lower end of the functional rod 2 passes through the through hole of the lower support member and is connected to the gap of the through hole of the lower support member, wherein, when the lower support member 34 is fixed, the upper support member 33 as a spring component or as a functional platform can realize the function of vibration reduction, after the upper support member 33 is subjected to vibration or other impact, the third spring 35 is first used as the first-level buffer, when the upper support member 33 drives the functional rod 2 to move downward, the internal steel ball is in the function Under the action of the friction force of the functional rod 2, there is a tendency to follow the movement of the functional rod 2 or there is actually a downward displacement, thereby changing the pressure between the steel ball and the functional rod 2, and then adaptively adjusting the friction between the functional rod 2 and the steel ball. When the steel ball has a downward displacement, the second elastic body 11 is squeezed and elastically deformed. As the movement speed of the functional rod 2 decreases, the second elastic body 11 has the elastic force to restore to its original shape under the action of its own elasticity, thereby being able to drive the steel ball to move upward, and then being able to change the friction between the functional rod 2 and the steel ball again, thereby achieving adaptive vibration reduction and buffering when subjected to external force impact due to the setting of the first elastic component and the second elastic component, thereby realizing a spring with variable intermediate damping or a device based on the spring.

[0091] Specifically, the damper-based device of the present invention includes a variety of combined structures.
