[0040] As Figures 1 to 7 shown, the present application provides a damping and vibration reduction device 100, including a damping and vibration suppression component 110 and an adsorption and connection component 120. Among them, the damping and vibration suppression component 110 includes a housing 111, a damping magnet 112 and a vibration block 113. A receiving space is defined in the housing 111. The damping magnet 112 is fixed to the inner wall of the receiving space. The vibration block 113 is provided with a first groove 11311. The vibration block 113 can move relative to the housing 111 along a first direction X, so that the damping magnet 112 is inserted into or withdrawn from the first groove 11311 to generate eddy current damping; the vibration block 113 forms a flow channel 114 with the inner wall of the receiving space in a second direction Y, and a fluid can flow in the flow channel 114 to generate viscous damping; the first direction X intersects with the second direction Y; the damping and vibration suppression component 110 is fixed to the adsorption and connection component 120. The adsorption and connection component 120 includes a suction cup 121, and the suction cup 121 can adsorb to a thin-walled member 200 along a third direction, and the third direction intersects with the second direction Y.

[0041] In this embodiment, the adsorption and connection component 120 fixes the damping and vibration suppression component 110 to the thin-walled member 200 through the suction cup 121. First, the suction cup 121 realizes the adsorption function by using the principle of pressure difference. After the suction cup 121 contacts the thin-walled member 200, the air between the suction cup 121 and the thin-walled member 200 is evacuated, a vacuum state is formed inside the suction cup 121, and the atmospheric pressure outside the suction cup 121 acts on the suction cup 121, so that the suction cup 121 can remain relatively fixed to the thin-walled member 200. In this way, it is avoided to apply a viscous coating on the surface of the thin-walled member 200 and the integrity of the thin-walled member 200 is protected.

[0042] Furthermore, after the damping and vibration suppression component 110 is fixed to the thin-walled part 200, when the thin-walled part 200 vibrates under the excitation of the riveting gun during the hammer riveting process, the vibration energy is transmitted to the damping and vibration suppression component 110 through the adsorption connection component 120, causing the vibration block 113 in the damping and vibration suppression component 110 to move relative to the housing 111 along the first direction X. Since the damping magnet 112 is fixed to the housing 111, the vibration block 113 also moves relative to the damping magnet 112. During the movement, the damping magnet 112 can repeatedly insert into or withdraw from the first groove 11311, thereby generating eddy currents. The eddy currents interact with the magnetic field, and the generated Lorentz force hinders the relative movement between the vibration block 113 and the damping magnet 112, that is, Lenz's law. At the same time, because the vibration block 113 has resistance, the eddy currents are converted into heat energy and consumed, generating a damping effect. When the thin-walled part 200 vibrates, eddy currents are continuously generated in the vibration block 113, and at the same time, the kinetic energy of the thin-walled part 200 is continuously converted into heat energy in the vibration block 113, causing the vibration of the thin-walled part 200 to gradually decay.

[0043] Furthermore, the vibration block 113 is placed in the accommodation space. The vibration block 113 divides the accommodation space into two compression chambers, which are respectively located at both ends of the vibration block 113 in the first direction X, and are respectively denoted as the first compression chamber and the second compression chamber. And a flow channel 114 is formed between the side wall of the vibration block 113 in the second direction Y and the inner wall of the accommodation space. The first compression chamber and the second compression chamber are connected through the flow channel 114. A fluid is placed in the accommodation space, and the fluid can flow between the first compression chamber and the second compression chamber through the flow channel 114. When the thin-walled part 200 vibrates, the vibration block 113 moves relative to the housing 111 along the first direction X. At this time, the vibration block 113 compresses one of the compression chambers, and the pressure in this compression chamber increases. The fluid located in this compression chamber flows through the flow channel 114 to the other compression chamber. When the fluid flows through the flow channel 114, a damping force is generated to hinder the relative movement between the vibration block 113 and the housing 111, consuming the mechanical energy transmitted from the thin-walled part 200 and causing the vibration of the thin-walled part 200 to gradually decay.

[0044] In this way, in this embodiment, the adsorption connection component 120 fixes the damping and vibration suppression component 110 to the thin-walled part 200 through the suction cup 121, avoiding smearing viscous paint on the surface of the thin-walled part 200 and protecting the integrity of the thin-walled part 200. The damping and vibration suppression component 110 forms eddy current damping through the first groove 11311 of the vibration block 113 and the damping magnet 112, and viscous damping generated by the vibration block 113 squeezing the fluid, together consuming the vibration energy generated by the thin-walled part 200 and causing the vibration of the thin-walled part 200 to gradually decay, improving the vibration damping effect.

[0045] It should be noted that, in order to achieve eddy current damping, the part of the vibration block 113 adjacent to the damping magnet 112 is made of a metal conductor material, such as copper or aluminum. In order to achieve viscous damping, the fluid can be common hydraulic oil, organic silicone oil, silicone-based glue, and extra-heavy suspension, and can also be air, and the flow channel 114 is relatively narrow.

[0046] Furthermore, along the first direction X, the length of the first groove 11311 is greater than the length of the damping magnet 112. In this way, the magnetic flux passing through the vibration block 113 during vibration is expanded, ensuring that the vibration block 113 does not collide with the damping magnet 112 while maximizing the eddy current damping effect.

[0047] Furthermore, the adsorption surface of the suction cup 121 is made of soft PVC material, that is, soft polyvinyl chloride. When the adsorption surface contacts the thin-walled part 200, the molecules on the adsorption surface interact with the molecules on the plane to form an adsorption force, thereby offsetting part of the gravity to maintain the relative fixation between the suction cup 121 and the thin-walled part 200.

[0048] Optionally, the housing 111 includes an upper housing 1111 and a lower housing 1112. The upper housing 1111 and the lower housing 1112 are fixed through a flange structure. The upper housing 1111 is provided with a first accommodation groove. Part of the lower housing 1112 is inserted into the first accommodation groove and encloses an accommodation space with the upper housing 1111. The lower housing 1112 is connected to the adsorption connection assembly 120.

[0049] Specifically, the upper housing 1111 is provided with a first accommodation groove, and the first accommodation groove forms a port on one end face of the upper housing 1111. Both the damping magnet 112 and the vibration block 113 can be loaded into the first accommodation groove from this port. Part of the lower housing 1112 is inserted into the first accommodation groove to block the port, so that the first accommodation groove forms a closed space, that is, the accommodation space. The lower housing 1112 and the upper housing 1111 are fixed through a flange, making the connection between the upper housing 1111 and the lower housing 1112 more reliable.

[0050] Furthermore, in this embodiment, the upper housing 1111 and the lower housing 1112 are inserted along the first direction X. The vibration block 113 reciprocates between the upper housing 1111 and the lower housing 1112. In this way, the upper housing 1111 and the lower housing 1112 can transmit the impact force of the vibration block 113 to the flange structure, which is shared by several bolts in the flange structure to reduce the deformation of the housing 111 caused by the impact of the vibration block 113.

[0051] Optionally, the accommodating space is columnar. The damping magnet 112 is fixed to the upper housing 1111 in the axial direction of the accommodating space. The first direction X and the third direction are both parallel to the axial direction of the accommodating space, and the second direction Y is perpendicular to the axial direction of the accommodating space. In this way, the vibration of the thin-walled member 200 is transmitted to the vibration block 113 along the axial direction of the accommodating space.

[0052] Further, the axis of the suction cup 121, the axis of the accommodating space, and the axis of the vibration block 113 coincide.

[0053] Optionally, the vibration block 113 includes a first vibration block 1131 and a second vibration block 1132. The first vibration block 1131 and the second vibration block 1132 are fixed along the axial direction of the accommodating space. The first vibration block 1131 is adjacent to the damping magnet 112. The first groove 11311 is formed in the first vibration block 1131. The second vibration block 1132 causes the first vibration block 1131 to have a moving tendency away from the damping magnet 112. In this way, the vibration block 113 is divided into two parts. The first vibration block 1131 is used to generate eddy current damping with the damping magnet 112, and the second vibration block 1132 is used to drive the first vibration block 1131 to move.

[0054] In this embodiment, the first vibration block 1131 and the second vibration block 1132 are connected by an adhesive.

[0055] Optionally, the damping magnet 112 and the upper housing 1111 are fixed by a threaded fastener 115, and a seal 116 is clamped between the damping magnet 112 and the upper housing 1111. In this way, through threaded connection, the damping magnet 112 and the upper housing 1111 are kept relatively fixed, and the seal 116 is used to block the connection gap between the threaded fastener 115 and the upper housing 1111 to prevent fluid from escaping from the gap out of the accommodating space.

[0056] In this embodiment, a second groove 11111 is formed on the side of the upper housing 1111 facing away from the accommodating space. The threaded fastener 115 sequentially passes through the damping magnet 112 and the upper housing 1111 and is threadedly connected to a nut 117 located in the second groove 11111.

[0057] In other embodiments, the threaded fastener 115 passes through the damping magnet 112 and is threadedly connected to the upper housing 1111.

[0058] Optionally, the adsorption connection assembly 120 further includes a suction cup cover 122 and a knob 123. The knob 123 is rotatably connected to the suction cup cover 122. The knob 123 is connected to the suction cup 121 by a screw 124. One end of the screw 124 is fixed to the suction cup 121, and the other end is threadedly connected to the knob 123.

[0059] Specifically, the suction cup cover 122 can move along the support knob 123, enabling the knob 123 to only rotate about the axis relative to the suction cup cover 122, while the suction cup cover 122 restricts the axial movement of the knob 123. When fixing the adsorption connection assembly 120 to the thin-walled part 200, first fix the suction cup 121 to the thin-walled part 200 so that the suction cup 121 cannot rotate relative to the thin-walled part 200. In this way, when rotating the knob 123, since the knob 123 is supported by the suction cup cover 122 and the distance from the thin-walled part 200 is constant, and the screw 124 is fixed to the suction cup 121 at one end and cannot rotate synchronously with the knob 123. When the knob 123 rotates, the screw 124 can move axially relative to the knob 123, thereby squeezing the suction cup 121 to evacuate the air between the suction cup 121 and the thin-walled part 200, and thus achieving stepless adjustment of the adsorption force.

[0060] Furthermore, the axis of the screw 124 coincides with the axis of the suction cup 121.

[0061] Optionally, a contact portion 1221 is provided at the circumferential edge of the suction cup cover 122, and the contact portion 1221 can abut the circumferential edge of the suction cup 121 against the thin-walled part 200 along the third direction. On the one hand, after the suction cup 121 is fixed to the thin-walled part 200, the suction cup cover 122 can be buckled with the thin-walled part 200 to form a cavity for protecting the suction cup 121, and the contact portion 1221 of the suction cup cover 122 can squeeze the circumferential edge of the suction cup 121 against the thin-walled part 200 to prevent air from entering the suction cup 121, changing the air pressure difference, and thus causing the fixation between the suction cup 121 and the thin-walled part 200 to fail.

[0062] Optionally, a second accommodation groove 11121 is provided on the side of the lower housing 1112 facing away from the upper housing 1111, and the knob 123 can be fixedly inserted into the second accommodation groove 11121. In this way, the knob 123 can rotate together with the lower housing 1112, facilitating installation by the staff.

[0063] Specifically, the port of the second accommodation groove 11121 is in a non-circular shape such as a waist shape or a polygon, and the knob 123 is adapted to the shape of the port, thus preventing the knob 123 from rotating relative to the lower housing 1112.

[0064] Generally, first fix the adsorption connection component 120 on the thin-walled part 200, and then fix the damping and vibration suppression component 110 on the adsorption connection component 120. That is, first turn the knob 123 to preliminarily fix the suction cup 121 to the thin-walled part 200. After aligning the opening of the second accommodation groove 11121 of the damping and vibration suppression component 110 with the knob 123, insert it, and then fix the damping and vibration suppression component 110 on the thin-walled part 200. If the fixation between the suction cup 121 and the thin-walled part 200 becomes unstable due to the increased load of the suction cup 121, the staff can rotate the damping and vibration suppression component 110 to turn the screw 124, so that the screw 124 further moves towards the thin-walled part 200, evacuating the air between the suction cup 121 and the thin-walled part 200 to increase the air pressure difference and enhance the adsorption ability.

[0065] Optionally, a blind hole 1232 is provided on the side of the knob 123 facing away from the suction cup 121, and a connecting magnet 125 is fixed in the blind hole 1232. The connecting magnet 125 can adsorb the lower housing 1112. In this way, the knob 123 adsorbs the lower housing 1112 through the connecting magnet 125 to maintain the relative fixation between the knob 123 and the lower housing 1112. The vibration energy generated by the thin-walled part 200 can be transmitted to the damping and vibration suppression component 110 through the knob 123 to reduce the energy loss during the transmission process. And through magnetic adsorption, the connection structure is also simplified, which is convenient for disassembly and installation.

[0066] Optionally, a stud 1231 is fixed in the blind hole 1232 of the knob 123, and the connecting magnet 125 is threadedly connected to the stud 1231. Specifically, the axial direction of the stud 1231 is parallel to the axial direction of the accommodation space, and the connecting magnet 125 is threadedly connected to the stud 1231, making the connection between the connecting magnet 125 and the knob 123 more reliable.

[0067] In other embodiments, internal threads are provided on the inner peripheral wall of the blind hole 1232, and external threads are provided on the outer peripheral wall of the connecting magnet 125. The connecting magnet 125 is directly threadedly connected to the knob 123.

[0068] In other embodiments, the connecting magnet 125 is in interference fit with the knob 123 in the blind hole 1232.
