Description

Technical Field

[0001] This utility model relates to the field of dampers, specifically to a damper with adjustable damping force. Background Technology

[0002] Viscoelastic dampers consist of a damping layer and a constrained steel plate. Common viscoelastic dampers include flat plate viscoelastic dampers and cylindrical shear-type viscoelastic dampers. Flat plate viscoelastic dampers consist of two constrained steel plates sandwiching a rectangular steel plate. A damping layer is sandwiched between the contact surfaces of the constrained steel plates and the middle steel plate. The steel plates and the damping layer are made into a whole by vulcanization. Under repeated axial force, the constrained steel plates and the central steel plate move relative to each other, causing the damping layer to undergo reciprocating shear deformation, thereby dissipating kinetic energy by absorbing heat.

[0003] While conventional viscoelastic dampers can achieve damping and dissipate the kinetic energy of axial forces, they cannot easily adjust the damping force according to the magnitude of the axial force and require further improvement.

[0004] Therefore, it is necessary to invent a damper with adjustable damping force. Utility Model Content

A rectangular steel plate is vertically inserted through the rectangular hole, and a first damping layer is fixed at the bottom of the rectangular steel plate.

The first damping layer and the third damping layer abut against each other.

[0010] Preferably, the bottom sides of the inner wall of the damper housing are symmetrically and vertically fixed with second electric push rods, and the top of the output shaft of the second electric push rod is fixed with an adjusting block. The top of the adjusting block is arc-shaped and abuts against the surface of the second constraint steel plate.

[0011] Preferably, the damping force adjustment component consists of two sets of end plates, which are symmetrically fixed on both sides of the damper housing. Each set of end plates consists of two plates, and a fixing bolt runs vertically between the two end plates in the same set. The end of the fixing bolt is threaded with a matching nut.

[0012] Preferably, the damper housing has symmetrical through holes on both sides, and an adjustment plate is horizontally inserted through the center of each through hole.

Figure 1 The present invention provides an adjustable damping force damper, including a damper shell 1, a cover plate 2 fixed on the top of the damper shell 1, a damping component movably installed on the inner side of the damper shell 1 through a damping force adjustment component, the damping component being a rectangular hole 3, the rectangular hole 3 being opened in the center of the cover plate 2, a rectangular steel plate 4 vertically penetrating the rectangular hole 3, and a first damping layer 5 fixed at the bottom end of the rectangular steel plate 4. Specifically, the first damping layer 5 can be made of viscoelastic materials such as asphalt or epoxy resin. The damping force adjustment component is a first electric push rod 6. The first electric push rod 6 is symmetrically fixed on both sides of the damper housing 1. The output shafts of the two first electric push rods 6 extend to the inside of the damper housing 1, and the output shafts of the two first electric push rods 6 are fixed with a first constraint steel plate 7. The output shafts of the two first electric push rods 6 are fixed with a second damping layer 8. The first damping layer 5 and the second damping layer 8 abut against each other. The second damping layer 8 can be made of viscoelastic materials such as asphalt or epoxy resin. Specifically, when the rectangular steel plate 4 is subjected to axial force and moves downward, the first damping layer 5 and the second damping layer 8 rub against each other, generating reciprocating shear deformation, thereby dissipating kinetic energy by absorbing heat, thus achieving the damping function. Moreover, the operator can control the two first constraint steel plates 7 to move towards each other or in opposite directions by operating the first electric push rod 6, which can conveniently control and adjust the distance between the two first constraint steel plates 7, thereby conveniently adjusting the mutual squeezing force between the first damping layer 5 and the second damping layer 8. The damping force can be conveniently adjusted according to the magnitude of the axial force, making it convenient to use.

[0019] It should be noted that the damper is electrically connected to an external controller and 220V AC mains power. The controller can be an existing technology device such as a computer. The precise control principle of the first electric push rod 6 is to achieve motion conversion through the mechanical cooperation of the servo motor and the lead screw. The status is monitored in real time with the help of devices such as encoders. Finally, the controller dynamically adjusts the output according to the deviation, thereby achieving precise control of position, speed and force within the millimeter or even micrometer range. Example 2

[0020] Please refer to the appendix. Figure 2 This utility model provides an adjustable damper with adjustable damping force. The damping force adjustment component is a rotating seat 9. The rotating seat 9 is symmetrically fixed on the top of both sides of the inner wall of the damper housing 1. A second constraint steel plate 10 is rotatably installed on each rotating seat 9. A third damping layer 11 is fixed at the opposite ends of the two second constraint steel plates 10. The third damping layer 11 can be made of viscoelastic materials such as asphalt or epoxy resin. The first damping layer 5 abuts against the third damping layer 11. A second electric push rod 12 is symmetrically and vertically fixed on both sides of the bottom of the inner wall of the damper housing 1. An adjustment block 13 is fixed at the top of the output shaft of the second electric push rod 12. The top of the adjustment block 13 is arc-shaped and abuts against the surface of the second constraint steel plate 10. Specifically, when the rectangular steel plate 4 is subjected to axial force and moves downward, the first damping layer 5 and the third damping layer 11 rub against each other, generating reciprocating shear deformation, thereby dissipating kinetic energy by absorbing heat, thus achieving the damping function. Moreover, the operator can control the two second constraint steel plates 10 to move towards each other or in opposite directions by operating the second electric push rod 12, so as to conveniently control and adjust the distance between the two second constraint steel plates 10, thereby conveniently adjusting the mutual squeezing force between the first damping layer 5 and the third damping layer 11. The damping force can be conveniently adjusted according to the magnitude of the axial force, making it convenient to use.

[0021] It should be noted that the damper is electrically connected to an external controller and 220V AC mains power. The controller can be an existing technology device such as a computer. The precise control principle of the second electric push rod 12 is to achieve motion conversion through the mechanical cooperation of the servo motor and the lead screw. The status is monitored in real time with the help of devices such as encoders. Finally, the controller dynamically adjusts the output according to the deviation, thereby achieving precise control of position, speed and force within the millimeter or even micrometer range. Example 3

[0022] Please refer to the appendix. Figure 3-4This utility model provides an adjustable damping force damper. The damping force adjustment component consists of two sets of end plates 14, which are symmetrically fixed on both sides of the damper housing 1. Each set of end plates 14 consists of two plates. A fixing bolt 15 is vertically inserted between the two end plates 14 in the same set. The end of the fixing bolt 15 is threaded with a matching nut 16. Through holes 17 are symmetrically opened on both sides of the damper housing 1. An adjustment plate 18 is horizontally inserted through the center of each through hole 17. Several adjustment holes 19 are equally spaced on the adjustment plate 18. The fixing bolt 15 can vertically penetrate any one of the adjustment holes 19. A third constraint steel plate 20 is fixed to the opposite end of each adjustment plate 18. A fourth damping layer 21 is fixed to the opposite end of each of the two third constraint steel plates 20. The fourth damping layer 21 can be made of viscoelastic materials such as asphalt or epoxy resin. The first damping layer 5 abuts against the fourth damping layer 21. Specifically, when the rectangular steel plate 4 is subjected to axial force and moves downward, the first damping layer 5 and the fourth damping layer 21 rub against each other, generating reciprocating shear deformation, thereby dissipating kinetic energy by absorbing heat, thus achieving the damping function. Furthermore, by disassembling the fixing bolt 15 and the matching nut 16, and passing the fixing bolt 15 through the adjustment holes 19 at different positions, the operator can control the two third constraint steel plates 20 to move towards each other or in opposite directions through the adjustment plate 18, thus conveniently controlling and adjusting the distance between the two third constraint steel plates 20. This allows for convenient adjustment of the mutual squeezing force between the first damping layer 5 and the fourth damping layer 21, and convenient adjustment of the damping force according to the magnitude of the axial force, making it easy to use.
