Description

Technical Field

[0001] The present application belongs to the technical field of flexible vibration-damping connection design of structures, and specifically relates to a flexible vibration-damping connection structure. Background Art

[0002] Engineering often involves connections between components. Currently, some of the connection parts of the connected components need to be able to stretch and have a certain flexibility to meet the needs of the connected components to get closer to or move away from each other. At the same time, they need to have a certain buffering effect to meet the requirements of vibration reduction between the connected components. For this reason, a connector made of elastic material is currently designed to connect the connected components. Since it has a large elastic deformation capacity and good stretchability, it can well meet the needs of the connected components to get closer to or move away from each other, and can meet the requirements of vibration reduction between the connected components. However, the connector made of elastic material needs to rely on large elastic deformation to provide sufficient deformation capacity. In actual application, in order to enable it to have a large elastic deformation, it is often designed to have a larger size structure, which takes up a larger space.

[0036] The following is combined with Figures 1 to 4 This application is described in further detail.

[0037] A flexible vibration-damping connection structure, comprising:

[0038] A first support plate 1;

[0039] A second support plate 2 is arranged opposite to the first support plate 1;

[0040] A plurality of first support bars 3 are arranged between the first support plate 1 and the second support plate 2, with one end connected to the first support plate 1;

[0041] A plurality of second support bars 4 are arranged between the first support plate 1 and the second support plate 2, one end of the second support bar 4 is connected to the second support plate 2, and the second support bars 3 are staggered with each other;

[0042] A plurality of groups of first elastic sheets 5, wherein each first elastic sheet 5 of each group of first elastic sheets 5 is arranged axially on a corresponding first support bar 3;

[0043] Multiple groups of second elastic sheets 6, each group of second elastic sheets 6 is arranged axially on a corresponding second support bar 4; each first elastic sheet 5 on each first support bar 3 is staggered with each second elastic sheet 6 on its adjacent second support bar 4.

[0044] For the flexible vibration-damping connection structure disclosed in the above embodiment, it can be understood by those skilled in the art that the outer sides of the first support plate 1 and the second support plate 2 can be respectively connected to the two connected parts. In the process of the two connected parts approaching or moving away from each other, the first support plate 1 and the second support plate 2 can be driven to move toward or away from each other, thereby causing the first support bars 3 and the second support bars 4 to move relative to each other, and causing the first elastic sheets 5 and the second elastic sheets 6 on the first support bars 3 and the second support bars 4 to move relative to each other, and the first elastic sheets 5 in each group of the first elastic sheets 5 and the second elastic sheets 6 in the corresponding ... The elastic sheets 6 squeeze each other and deform, so as to adapt to the needs of the two connected parts moving closer to or farther away from each other, and can play a certain buffering role, which can meet the vibration reduction requirements between the two connected parts and realize the flexible connection between the two connected parts. In addition, the first elastic sheets 5 and the second elastic sheets 6 of each group on the first support bar 3 and the second support bar 4 move relative to each other, and each first elastic sheet 5 in each group of first elastic sheets 5 and each first elastic sheet 6 in the corresponding group of second elastic sheets 6 squeeze each other and deform, which can generate a large friction force between them, and the two connected parts can be reliably connected by relying on this friction force.

[0045] Regarding the flexible vibration-damping connection structure disclosed in the above embodiment, those skilled in the art can also understand that it realizes flexible connection and plays a buffering role by mutual squeezing and deformation between the first elastic piece 5 and the second elastic piece 6. The greater the distance between each first elastic piece 5 and the corresponding second elastic piece 6 as the first support plate 1 and the second support plate 2 change relative to each other, the greater the deformation, the greater the friction between them, and the stronger the load absorption and dissipation capacity. It can absorb and dissipate the load in a progressive and rapid manner, and can obtain a relatively large load absorption and dissipation effect without generating large deformation, thereby playing a better buffering and vibration reduction role.

[0046] In some optional embodiments, in the flexible vibration-damping connection structure, the first support plate 1 and each first support bar 3 are integrally formed;

[0047] Each first support bar 3 and each first elastic piece 5 thereon are formed integrally.

[0048] In some optional embodiments, in the flexible vibration-damping connection structure, each second support bar 4 and each second elastic sheet 6 thereon are integrally formed;

[0049] One end of each second support bar 4 connected to the second support plate 2 has a dovetail-shaped protrusion;

[0050] Each second support plate 2 has a plurality of dovetail grooves; each dovetail-shaped protrusion is correspondingly engaged with a dovetail groove.

[0051] In some optional embodiments, in the flexible vibration-damping connection structure, the two first support bars 3 located on the outer sides of each first support bar 3 are called outer support bars;

[0052] There are two supporting protrusions 7 on the second supporting plate 2; two outer supporting strips are located between the two supporting protrusions 7; and each supporting protrusion 7 is correspondingly fitted with one outer supporting strip.

[0053] As for the flexible vibration-damping connection structure disclosed in the above embodiment, those skilled in the art can understand that the second support plate 2 is provided with two support protrusions 7 corresponding to the two outer support bars located on the outer sides of each first support bar 3, which can prevent the first support plate 1 and the second support plate 2 from shaking during the movement toward or away from each other, increase the stability of the structure, and make it have a certain rigidity so that it can withstand a certain lateral load, and can prevent the adjacent first support bars 3 and second support bars 4 from being too close to each other and causing squeezing damage to the first elastic sheets 5 and the second elastic sheets 6 thereon.

[0054] In some optional embodiments, in the flexible vibration-damping connection structure, each outer support bar has a guide groove extending in the axial direction;

[0055] Each supporting protrusion 7 has a guide protrusion 8 that is correspondingly engaged with a guide groove and can slide in the guide groove.

[0056] As for the flexible vibration-damping connection structure disclosed in the above embodiment, it can be understood by those skilled in the art that, by cooperating with the guide protrusion 8 and the guide groove, the first support plate 1 and the second support plate 2 can be prevented from being dislocated during the movement toward or away from each other, thereby increasing the stability of the structure and preventing the first elastic sheet 5 and the second elastic sheet 6 on the adjacent first support bar 3 and the second support bar 4 from being dislocated, thereby reducing their buffering and vibration-damping capabilities.

[0057] For the flexible vibration-damping connection structure disclosed in the above embodiment, technicians in the field can also understand that during the assembly process, the guide protrusions 8 can be first inserted into the corresponding guide grooves to preliminarily define the relative positions of the first support plate 1 and the second support plate 2, and then the dovetail-shaped protrusions on each second support bar 4 can be inserted into the corresponding dovetail grooves on the second support plate 2, while the first elastic sheets 5 and the second elastic sheets 6 on the adjacent first support bars 3 and second support bars 4 are staggered.

[0058] In some optional embodiments, in the above-mentioned flexible vibration-damping connection structure, the first support plate 1 has two stop protrusions 9; each stop protrusion 9 is arranged opposite to a support protrusion 7, so that they can abut against each other when the first support plate 1 and the second support plate are too close, thereby preventing the first support plate 1 and the second support plate 2 from getting further too close, thereby preventing the first elastic sheet 5 and the second elastic sheet 6 on the first support bar 3 and the second support bar 4 from being excessively deformed and damaged, and preventing the first elastic sheet 5 and the second elastic sheet 6 on adjacent first support bars 3 and the second support bar 4 from being detached from each other.

[0059] In some optional embodiments, in the flexible vibration-damping connection structure, each stop protrusion 9 has a stop surface facing the support protrusion 7; each stop surface is recessed to form a stop groove; and the end of each stop groove located on the corresponding stop surface is in an inwardly tapered shape;

[0060] The flexible vibration-damping connection structure also includes:

[0061] There are two support rods 10, one end of each support rod 10 is connected to a corresponding support protrusion 7, and the other end is tapered and points to the corresponding stop groove located on the stop surface.

[0062] For the flexible vibration-damping connection structure disclosed in the above embodiment, it can be understood by those skilled in the art that, when the first support plate 1 and the second support plate 2 are too close to each other, the tapered ends of the two support rods 10 will be inserted into the ports of the corresponding stop grooves on the stop surface, thereby enabling the first support plate 1 and the second support plate 2 to be further close to each other, and the tapered ends of the two support rods 10 can provide a large buffering force during the insertion process of the corresponding stop grooves on the stop surface ports, thereby having a large buffering and vibration-damping effect. When the load borne by the first support plate 1 and the second support plate 2 is instantly too large, the tapered ends of the two support rods 10 can destroy the port structure of the corresponding stop groove on the stop surface, thereby further inserting into the strip groove below the corresponding stop groove. In this process, a large amount of energy can be absorbed and released, thereby having a large buffering and vibration-damping effect, and effectively protecting the various functional components of the flexible vibration-damping connection structure from damage. When the load borne by the first support plate 1 and the second support plate 2 is large, the two stop protrusions 9 will eventually abut against the corresponding support protrusions 7, thereby preventing the first support plate 1 and the second support plate 2 from being further close to each other.

[0063] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to in detail.

[0064] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or replacements to the relevant technical features, and the technical solutions after these changes or replacements will fall within the scope of protection of the present application.
