The springs are mainly used to absorb shocks of large amplitude, for example, to cushion the frame of a vehicle, while the rubber pads are mainly used to absorb shocks of small amplitude and high frequency. In addition, the spring has the advantages that the self rigidity can be changed by selecting springs with different elastic coefficients and setting different compression amounts, so that the spring is suitable for the vibration of different impact forces, and the spring has the defects that the spring is basically used for damping in one direction and is easy to lose efficacy; rubber pad among the prior art is mostly solid columnar structure, and the advantage is in providing more soft shock attenuation effect, and can be used for the ascending shock attenuation in more directions, and the defect of rubber pad is that the ability of absorbing the great vibrations of amplitude is relatively poor.

In the prior art, in order to enable the shock absorption component made of rubber material to absorb shock with larger amplitude, the shock absorption component is made into an annular structure, for example, a long circular structure, and the middle part of the long circular structure is a hollow structure, so that the shock absorption component can absorb shock with larger amplitude.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.

As shown in fig. 1 to 3, an embodiment of the present invention discloses a damper mechanism, including: a damper ring 10, a damper core 20, and a connecting member.

The damping ring 10 is injection moulded from a rubber material, the damping ring 10 having an oblong ring profile, which results in the damping ring 10 having an upper flat section 11 and a lower flat section 12. Since the middle part of the damping ring 10 is a hollow structure, the whole damping mechanism has a condition of absorbing vibration with large amplitude.

The damping core 20 comprises two U-shaped plates 21, the two U-shaped plates 21 are arranged in an interlocking manner, that is, the notches of the two U-shaped plates 21 are opposite, so that the two U-shaped plates 21 enclose a long circular structure matched with the damping ring 10, and a preset interlocking gap 22 is arranged between the two U-shaped plates 21, so that the enclosed long circular structure is a split structure. The two U-shaped plates 21 are embedded in the damping ring 10, and specifically, in the process of manufacturing the damping ring 10 by using a rubber material, the two U-shaped plates 21 are integrally injection-molded with the damping ring 10, and the combination capability of the inside of the damping ring 10 and the U-shaped plates 21 is increased by filling pits on the inner plate surface and the outer plate surface of the U-shaped plates 21. Preferably, U-shaped plate 21 is formed from a spring steel plate by a hot press bending process.

Through embedding two buckled U-shaped plates 21 in the damping ring 10, the rigidity of the damping mechanism can be increased, and the damping mechanism can adapt to the vibration of large impact force.

The connecting member includes an upper connecting bolt 31 and a lower connecting bolt 32; go up connecting bolt 31 and wear to establish level district section 11, and go up nut 311 backstop of connecting bolt 31 in last inboard of level district section 11, level district section 12 is worn to establish down to connecting bolt 32 down, and the nut 321 backstop of connecting bolt 32 is in the inboard of level district section 12 down, and arc breach 211 has all been seted up to the side at the both ends of U-shaped plate 21, the arc breach 211 of two U-shaped plates 21 encloses into the hole, upper and lower two connecting bolt wear to establish corresponding hole, this avoid connecting bolt to wear to establish when damping ring 10 with the U-shaped plate 21 in the damping ring 10 take place to interfere, in addition, the diameter of the hole that encloses is greater than connecting bolt's diameter.

As shown in fig. 4, the lower connecting bolt 32 is used for assembling the damping mechanism with the supporting platform 102 by penetrating the supporting platform 102 and matching with the sleeve nut 60, and the upper connecting bolt 31 is used for assembling the damping mechanism with the functional device 101 by penetrating the bottom of the functional device 101 and matching with the sleeve nut 60, so that the damping mechanism is assembled in place for absorbing the shock generated by the device.

The shock absorbing mechanism provided by the above embodiment of the present invention has the advantages that:

1. the shock absorption core 20 made of a metal plate matched with the shock absorption ring 10 in shape is embedded in the shock absorption ring 10 made of a rubber material, so that the shock absorption ring 10 can absorb shock of large impact, and the shock absorption mechanism can be applied to absorption of equipment with shock of large impact.

2. Through making two U-shaped plates 21 to detain and setting up between two U-shaped plates 21 and predetermine detain gap 22, and then make long annular shock attenuation core 20 form and become the components of a whole that can function independently structure, this has improved the ability that damper absorbed the horizontal direction vibrations (learn through the experiment, damper absorbs rigidity on the horizontal direction can be very big if setting up to confined long annular structure, damper 20, and the ability of absorbing the horizontal direction vibrations is relatively poor).

In some preferred embodiments, a cylindrical spring 40 is further added to the hollow structure of the upper flat section 11 and the lower flat section 12 of the shock-absorbing ring 10. Specifically, a screw 51 is arranged on a nut 311 of the upper connecting bolt 31, a threaded sleeve 52 is sleeved on the screw 51, the threaded sleeve 52 and the screw 51 form a threaded fit, a locking nut 54 is further sleeved on the screw 51, and the rotation of the threaded sleeve 52 is limited by screwing the locking nut 54; an upper positioning column 53 is formed on the threaded sleeve 52; a lower positioning column 322 is formed on a nut 321 of the lower connecting bolt 32; the cylindrical spring 40 is disposed between the threaded sleeve 52 and the nut 321 of the lower connecting stud 51, and the upper positioning post 53 extends into the cylindrical spring 40 from the upper end of the cylindrical spring 40, and the lower positioning post 322 extends into the cylindrical spring 40 from the lower end of the cylindrical spring 40 to limit the cylindrical spring 40 from being laterally displaced and coming out of the hollow structure. Thus, the compression amount of the cylindrical spring 40 can be adjusted by screwing the screw sleeve 52.

The above-mentioned damper mechanism that has add the compression capacity that can adjust cylindrical spring 40 has the advantage:

the stiffness of the damper mechanism in the vertical direction can be increased by adding the cylindrical spring 40, and more importantly: the whole damping mechanism can adjust the rigidity in the vertical direction by additionally arranging a structure for adjusting the compression amount of the columnar spring, and the resonance phenomenon of the functional equipment 101 and the damping mechanism can be effectively avoided by adjusting the rigidity of the damping mechanism.
