Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a shock absorber structure. Background Art

[0002] In mechanical manufacturing, common vibration damping mechanisms and spring structures are widely used in mechanical parts and structural assemblies of different specifications and requirements. For example, the suspension system in a washing machine is generally composed of four suspension rod shock absorbers.

[0003] For example, Chinese public document CN114738436A discloses a high-damping spring shock absorber, which includes a top plate and a base arranged opposite to each other, a number of springs arranged between the top plate and the base, a cylindrical wall provided on the upper surface of the base to form a cavity structure, a damping mechanism provided between the cavity structure and the top plate, and adjusting screws arranged opposite to each other on the top plate and the base, and the relative adjusting screws are connected by a connecting plate; it can achieve rapid vibration attenuation and can set the vibration stroke of the shock absorber.

[0004] Although the above-mentioned shock absorber can reduce vibration through the spring, it does not have a damping system. In a short period of time, when the load on the boom shock absorber changes significantly, the length of the spring causes vibration during its rapid recovery, which is not conducive to practical use. Utility Model Content

[0005] In response to the defects in the existing technology, the utility model provides a shock absorber structure, which is equipped with a damping mechanism. When the load on the shock absorber changes significantly in a short period of time, the length of the spring changes slowly, thereby reducing the generation of vibration. At the same time, a relative buffer mechanism is provided to reduce the resonance caused by the contraction of the spring.

[0006] In order to solve the above technical problems, the present invention proposes the following technical solutions:

[0007] A shock absorber structure includes a metal rod, a sleeve structure and a top cover, the sleeve structure and the top cover are respectively located at both ends of the metal rod, the sleeve structure includes a sleeve head and a resistance cylinder, the sleeve head and the resistance cylinder are fixedly connected, a damping mechanism, a spring and a shock-absorbing sponge are embedded in the resistance cylinder, the spring is vertically embedded therein and sleeved with the metal rod at the same time, the damping mechanism is located at the bottom of the spring, the shock-absorbing sponge is located on both sides of the spring, the damping mechanism as a whole includes a fixing ring, a first connecting rod, a spring sleeve, a damping layer and a positioning seat, the first connecting rod, the spring sleeve and the damping layer are matched and embedded in the positioning seat, the fixing ring is located on the outside of the first connecting rod, the inside of the resistance cylinder is fixedly connected to the second connecting rod, a stabilizing plate and a buffer strip, the stabilizing plate and the buffer strip are both fixedly connected to the second connecting rod,

[0008] Furthermore, two groups of shock-absorbing sponges are provided as a whole and fixedly arranged at both sides of the interior of the resistance tube. The shock-absorbing sponges are provided as a whole in an arc-shaped inward convex arrangement, and the protruding positions directly contact the metal rods inside the resistance tube.

[0009] Furthermore, the shock-absorbing sponge is simultaneously inserted into the spring from the side thereof and is located inside the spring.

[0010] Furthermore, the first connecting rod, the spring sleeve and the damping layer are vertically connected in sequence. The spring sleeve is configured as a metal compression spring and is sleeved on the first connecting rod. The damping layer and the first connecting rod are configured in a "T" shape.

[0011] Furthermore, the damping layer is entirely configured as a hard rubber layer with an arc-shaped concave surface, and is also configured to fit the metal rod inside the resistance tube.

[0012] Furthermore, the second connecting rod, the stabilizing plate and the buffer strip are matched with each other, the stabilizing plate and the second connecting rod are connected in a T-shape as a whole, and the stabilizing plate is embedded in the inner side of the spring and closer to the outside.

[0013] Furthermore, the buffer strip is located on both sides of the root of the second connecting rod as a whole, is configured as a rubber strip, and is located on the outside of the spring.

[0014] From the above technical solution, it can be seen that the beneficial effects of the utility model are:

[0015] In the present invention, when the spring is deformed, compressed and rebounded, the lateral resonance generated during the process contacts the shock-absorbing sponges on both sides. Since the shock-absorbing sponges themselves have elasticity and shock-absorbing properties and are arranged in an arc-shaped inward convex shape, the shock-absorbing sponges can achieve the effect of buffering and offsetting the lateral resonance.

[0016] The utility model makes contact with the outer side of the metal rod through the damping layer. When the sleeve slides on the metal rod, the friction force generated by the damping layer and the resistance tube limits the sliding speed of the sleeve, so that the shock absorber cannot generate large vibration.

[0017] In the utility model, when the spring generates lateral resonance, the second connecting rod at the inner side contacts the spring in the vibrating state, thereby achieving the effect of quickly offsetting the vibration. At the same time, the buffer strip inside and outside performs buffering and offsetting, thereby having a good vibration reduction effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0026] See Figure 1-4 As shown, a shock absorber structure includes a metal rod 1, a sleeve structure 2 and a top cover 3. The sleeve structure 2 and the top cover 3 are respectively located at the two ends of the metal rod 1. The sleeve structure 2 includes a sleeve head 4 and a resistance cylinder 5. The sleeve head 4 and the resistance cylinder 5 are fixedly connected. A damping mechanism 6, a spring 7 and a shock-absorbing sponge 8 are embedded in the resistance cylinder 5. The spring 7 is vertically embedded therein and is sleeved with the metal rod 1. The damping mechanism 6 is located at the bottom position of the spring 7. The shock-absorbing sponge 8 is located on both sides of the spring 7. The damping mechanism 6 as a whole includes a fixing ring 9, a first connecting rod 10, a spring sleeve 11, a damping layer 12 and a positioning seat 13. The first connecting rod 10, the spring sleeve 11 and the damping layer 12 are matched and embedded in the positioning seat 13. The fixing ring 9 is located on the outside of the first connecting rod 10. The inside of the resistance cylinder 5 is fixedly connected to the second connecting rod 14, a stabilizing plate 15 and a buffer strip 16. The stabilizing plate 15 and the buffer strip 16 are both fixedly connected to the second connecting rod 14.

[0027] In this embodiment, the shock-absorbing sponges 8 are provided in two groups, which are fixedly arranged at both sides of the interior of the resistance tube 5. The shock-absorbing sponges 8 are arranged in an arc-shaped inward convex shape, and the protruding positions directly contact the metal rods 1 inside the resistance tube 5.

[0028] The shock-absorbing sponge 8 is simultaneously inserted into the spring 7 from the side thereof and is located on the inner side of the spring 7;

[0029] When the spring 7 is deformed, compressed and rebounded, the lateral resonance generated during the process contacts the shock-absorbing sponge 8 on both sides. Since the shock-absorbing sponge 8 itself has elasticity and shock-absorbing effects and is arranged in an arc-shaped inward convex shape, the shock-absorbing sponge 8 can buffer and offset the lateral resonance.

[0030] The first connecting rod 10, the spring sleeve 11, and the damping layer 12 are vertically connected in sequence. The spring sleeve 11 is configured as a metal compression spring and is sleeved on the first connecting rod 10. The damping layer 12 and the first connecting rod 10 are configured in a "T" shape.

[0031] The damping layer 12 is entirely configured as a hard rubber layer with an arc-shaped concave surface, and is also configured to fit the metal rod 1 inside the resistance tube 5;

[0032] The damping layer 12 is in contact with the outer side of the metal rod 1. When the sleeve 4 slides on the metal rod 1, the friction force generated by the damping layer 12 and the resistance tube 5 limits the sliding speed of the sleeve 4, so that the shock absorber cannot generate large vibrations.

[0033] The second connecting rod 14, the stabilizing plate 15 and the buffer strip 16 are provided in a matching manner. The stabilizing plate 15 and the second connecting rod 14 are connected in a T-shape as a whole. At the same time, the stabilizing plate 15 is embedded in the inner side of the spring 7.

[0034] The buffer strip 16 is located on both sides of the root of the second connecting rod 14 and is configured as a rubber strip and is located outside the spring 7.

[0035] When the spring 7 generates lateral resonance, the second connecting rod 14 at the inner side contacts the spring 7 in the vibrating state, achieving the effect of quickly offsetting the vibration. At the same time, it cooperates with the buffer strip 16 inside and outside to buffer and offset, which has a good vibration reduction effect.

[0036] Working principle: When the resistance tube 5 and the sleeve 4 are lightly loaded as a whole, the spring 7 is compressed and shortened to support the sleeve 4. When the load is heavier, the spring 7 continues to shorten. At this time, the shock-absorbing sponge 8 continues to provide support to the resistance tube 5 as a whole from the inside. During the compression deformation and rebound process of the spring 7, the shock-absorbing sponge 8, the stabilizing plate 15 and the buffer strip 16 reduce its lateral resonance. When the sleeve 4 slides on the metal rod 1, the friction force generated by the damping layer 12 and the resistance tube 5 on the metal rod 1 limits the sliding speed of the sleeve 4, so that the shock absorber cannot generate large vibrations.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
