The lower middle fixing plate 4.6 is provided with countersunk screws, and the lower middle fixing plate 4.6 is connected to the lower middle locking ring 4.2 by passing the countersunk screws through the inner ring of the lower air diaphragm 4.4;

[0036] The lower outer locking ring 4.5 is provided with countersunk screws, and the lower outer locking ring 4.5 is connected to the lower bottom plate 4.1 by passing the countersunk screws through the lower air diaphragm 4.4. And the lower middle locking ring 4.2 is located inside the lower outer locking ring 4.2. The lower inner locking ring 4.7 is provided with countersunk screws, and the lower inner locking ring 4.7 is connected to the lower inner fixing plate 4.3 by passing the countersunk screws through the lower air diaphragm 4.4;

[0037] The middle horizontal plate 4.8 is connected to the lower inner fixing plate 4.3. Above the middle horizontal plate 4.8, there is also a lower connecting piece 4.9 of the inner vertical plate. The lower connecting piece 4.9 of the inner vertical plate is fixedly connected to the lower middle locking ring 4.2. In the middle of the lower connecting piece 4.9 of the inner vertical plate, there is a lower air inlet interface 1.7. The air inlet passage communicated with the air inlet interface 1.7 extends into the lower bottom plate 4.1;

[0038] On the top surface of the lower connecting piece 4.9 of the inner vertical plate, there are also several air inlets 3, which are respectively connected to the upper and lower shock absorption units 4 and the side shock absorption unit 2 to provide air flow input;

[0039] Specifically, the upper shock absorption unit 1 and the lower shock absorption unit 4 are arranged at intervals up and down. There are several side shock absorption units 2 on the periphery of the upper shock absorption unit 1 and the lower shock absorption unit 4. The upper and lower shock absorption units 4 and the side shock absorption unit 2 enclose a box-shaped structure with a hollow interior. Among them, the lower shock absorption unit 4 includes: a lower bottom plate 4.1, a lower middle locking ring 4.2, a lower inner fixing plate 4.3, a lower air diaphragm 4.4, a lower outer locking ring 4.5, a lower middle fixing plate 4.6, a lower inner locking ring 4.7, and a middle horizontal plate 4.8;

[0040] There is a cavity inside the lower bottom plate 4.1. The lower inner fixing plate 4.3 is arranged in the cavity and is fixedly connected to the lower bottom plate 4.1 by screws; there are multiple countersunk screws in the lower middle fixing plate 4.6. The countersunk screws pass through the lower air diaphragm 4.4 and are fixedly connected to the lower middle locking ring 4.2 to form a whole. The lower middle fixing plate 4.6 and the lower middle locking ring 4.2 sandwich the lower air diaphragm 4.4 in the middle, and the lower air diaphragm 4.4 is restricted between the lower middle fixing plate 4.6 and the lower middle locking ring 4.2 by the countersunk screws to prevent the lower air diaphragm 4.4 from detaching from the lower middle fixing plate 4.6 and the lower middle locking ring 4.2 when subjected to extrusion force; and the lower middle locking ring 4.2 is also located in the cavity and is located outside the lower inner fixing plate 4.3. At the same time, there is a gap between the inner wall of the lower middle locking ring 4.2 and the outer wall of the lower inner fixing plate 4.3. The cavity of the lower bottom plate 4.1 forms a sealed space through the setting of the lower air diaphragm 4.4;

[0041] There are countersunk screws in the lower inner locking ring 4.7. The countersunk screws pass through the inner ring of the lower air diaphragm 4.4 and are fixedly connected to the lower inner fixing plate 4.3 to fix the lower air diaphragm 4.4 above the lower inner fixing plate 4.3. There are also countersunk screws in the lower outer locking ring 4.5. The countersunk screws pass through the outer ring of the lower air diaphragm 4.4 and are fixedly connected to the lower bottom plate 4.1 to fix the outer ring of the lower air diaphragm 4.4 above the lower bottom plate 4.1. At this time, only the lower middle locking ring 4.2 and the lower middle fixing plate 4.6 are not directly connected to the lower bottom plate 4.1 and the lower inner fixing plate 4.3. Therefore, the lower middle locking ring 4.2 and the lower middle fixing plate 4.6 are floating and movable;

[0042] The middle cross plate 4.8 is fixedly connected to the lower middle locking ring 4.2. The movement of the lower middle locking ring 4.2 can drive the movement of the middle cross plate 4.8. An inner side vertical plate lower connecting part 4.9 is also provided above the middle cross plate 4.8. The inner side vertical plate lower connecting part 4.9 is fixedly connected to the lower inner locking ring 4.7 and the lower inner fixing plate 4.3 by screws. An air inlet interface 1.7 is also provided in the middle of the inner side vertical plate lower connecting part 4.9. The air inlet channel connected to the air inlet interface 1.7 extends into the cavity of the lower bottom plate 4.1. Thus, the lower shock absorption unit 4 is assembled. Then, it is inflated through the air inlet interface 1.7 to test whether there is an air leakage problem;

[0043] Working principle: When inflating through the air inlet interface 1.7, the air flow enters the sealed cavity. When the air pressure reaches a certain level, the air flow will act on the lower air diaphragm 4.4 through the extrusion between the lower middle locking ring 4.2 and the lower inner fixing plate 4.3, causing the lower air diaphragm 4.4 to expand and deform. The lower air diaphragm 4.4 will push up the middle cross plate 4.8. When the middle cross plate 4.8 is under pressure, it will squeeze the lower air diaphragm 4.4 and compress the air inside it. The compression of the air will absorb the impact pressure, thus achieving the shock absorption effect.

[0044] Furthermore, the upper shock absorption unit 1 includes: an upper bottom plate 1.1, an upper inner fixing plate 1.2, an upper air diaphragm 1.3, an upper inner locking ring 1.4, and an upper outer locking ring 1.5;

The upper inner locking ring 1.4 is also fixedly connected to an inner side vertical plate upper connecting part 1.6. An air inlet interface 1.7 is also connected to the middle of the bottom surface of the inner side vertical plate upper connecting part 1.6. The air inlet channel connected to the air inlet interface 1.7 extends into the upper bottom plate 1.1;

[0046] Specifically, a cavity is also provided in the middle of the upper base plate 1.1, the upper inner fixing plate 1.2 is located in the cavity of the upper base plate 1.1, the upper inner locking ring 1.4 is fixedly connected to the upper inner fixing plate 1.2 by a countersunk screw, and an upper air diaphragm 1.3 is sandwiched between the upper inner locking ring 1.4 and the upper inner fixing plate 1.2, wherein the countersunk screw passes through the upper air diaphragm 1.3 to prevent the upper air diaphragm 1.3 from escaping from between the upper inner locking ring 1.4 and the upper inner fixing plate 1.2; the upper outer locking ring 1.5 is fixedly connected to the upper base plate 1.1 by a countersunk screw, and the countersunk screw passes through the outer ring of the upper air diaphragm 1.3 to fix the outer ring of the upper air diaphragm 1.3 between the upper outer locking ring 1.5 and the upper base plate 1.1, and at the same time the upper outer locking ring 1.5 is arranged at intervals with the upper inner locking ring 1.4; the upper air diaphragm 1.3 forms a sealed space in the cavity of the upper base plate 1.1 through the fixation of the upper outer locking ring 1.5; the upper inner locking ring 1.4 is also fixedly connected to the connecting piece 1.6 on the inner vertical plate, and the side vibration damping unit 2 is connected to the connecting piece 1.6 on the inner vertical plate and the lower connecting piece 4.9 on the inner vertical plate, thereby connecting the upper vibration damping unit 1 and the lower vibration damping unit 4 together; an air intake interface 1.7 is also connected to the middle of the connecting piece 1.6 on the inner vertical plate, and the air intake duct connected to the air intake interface 1.7 extends into the cavity of the upper base plate 1.1. At this point, the upper vibration damping unit 1 is assembled, and then the air flow is filled through the air intake interface 1.7 to test whether the upper vibration damping unit 1 has a leakage problem.

[0047] Furthermore, each of the side vibration reduction units 2 comprises: an outer side vertical plate 2.1.1, a side inner locking ring 2.1.2, a side air diaphragm 2.1.3, a side outer locking ring 2.1.4, a side inner fixing plate 2.1.5, and an inner side vertical plate 2.1.6;

[0048] The side inner locking ring 2.1.2 is located inside the outer vertical plate 2.1.1, the side inner fixing plate 2.1.5 is provided with a countersunk screw, the countersunk screw passes through the side air diaphragm 2.1.3 to connect the side inner fixing plate 2.1.5, the side air diaphragm 2.1.3 and the side inner locking ring 2.1.2 together, the side outer locking ring 2.1.4 is provided with a countersunk screw, the countersunk screw passes through the side air diaphragm 2.1.3 and is connected to the outer vertical plate 2.1.1, the inner vertical plate 2.1.6 is fixedly connected to the side inner fixing plate 2.1.5, and the inner vertical plate 2.1.6 is also provided with an air inlet interface 1.7, and the air inlet duct connected to the air inlet interface 1.7 extends into the outer vertical plate 2.1.1;

[0049] Specifically, in this application, taking four side shock-absorbing units 2 as an example, the four side shock-absorbing units 2 are respectively located on the front, rear, left, and right sides. Combined with the upper and lower shock-absorbing units 4, shock absorption in six directions is achieved. Among them, the outer vertical plate 2.1.1 is provided with a cavity, the inner side fixing plate 2.1.5 is located in the cavity of the outer vertical plate 2.1.1, the inner side locking ring 2.1.2 is fixedly connected to the inner side fixing plate 2.1.5 through a countersunk screw, the inner ring of the side air diaphragm 2.1.3 is located between the inner side fixing plate 2.1.5 and the inner side locking ring 2.1.2, and the countersunk screw passes through the side air diaphragm 2.1.3. The outer side locking ring 2.1.4 is fixedly connected to the outer vertical plate 2.1.1 through a countersunk screw, and the countersunk screw passes through the outer ring of the measuring air diaphragm to fix the outer ring of the side air diaphragm 2.1.3 between the outer side locking ring 2.1.4 and the outer vertical plate 2.1.1. Thus, a sealed space is formed in the cavity of the outer vertical plate 2.1.1 through the side air diaphragm 2.1.3. The inner vertical plate 2.1.6 is fixedly connected to the inner side locking ring 2.1.2 through a screw, and an air inlet interface 1.7 is connected to the middle of the inner vertical plate 2.1.6. The air inlet passage connected to the air inlet interface 1.7 extends into the cavity of the outer vertical plate 2.1.1.

[0050] Further, at least one concave position is provided on each side of the middle cross plate 4.8, the inner side lower connecting piece 4.9, the upper bottom plate 1.1, and the inner side upper connecting piece 1.6. The concave position is used to connect with the side shock-absorbing unit 2;

[0051] Specifically, at least one concave position is provided on each side of the middle cross plate 4.8, the inner side lower connecting piece 4.9, the upper bottom plate 1.1, and the inner side upper connecting piece 1.6. The upper end of the outer vertical plate 2.1.1 is fixedly connected to the concave position of the upper bottom plate 1.1, the lower end of the outer vertical plate 2.1.1 is fixedly connected to the concave position of the middle cross plate 4.8, the upper end of the inner vertical plate 2.1.6 is fixedly connected to the concave position of the inner side upper connecting piece 1.6, and the lower end of the inner vertical plate 2.1.6 is fixedly connected to the concave position of the inner side lower connecting piece 4.9. At this time, the upper and lower shock-absorbing units 4 and several side shock-absorbing units 2 form a box-shaped multi-directional shock-absorbing device.

[0052] It should be noted that a plurality of air inlets 3 are further provided at the top of the inner side lower connecting piece 4.9. The air inlets 3 are used to provide gas input. Among them, the upper shock-absorbing unit 1 and the lower shock-absorbing unit 4 are connected in series and share one air inlet 3. Each side shock-absorbing unit 2 occupies one air inlet 3, and marks are made in the air inlets 3 for easy identification in the later stage; each shock-absorbing unit has independent air intake. When used in combination with active shock absorption, a servo valve also needs to be installed for air supply. For example, when a reverse thrust is generated, the sensor detects the signal and will drive the servo valve to inflate to absorb the acting force.

[0053] Energy absorption process: The lower middle locking ring 4.2, the lower middle fixing plate 4.6 and the middle horizontal plate 4.8 are floating and movable; the upper bottom plate 1.1 and the upper outer locking ring 1.5 are floating and movable; the lower connecting piece 4.9 of the inner vertical plate is fixedly connected to the lower inner fixing plate 4.3 and will not move; the upper connecting piece 1.6 of the inner vertical plate is fixedly connected to the upper inner fixing plate 1.2 and will not move. The upper and lower ends of the inner vertical plate 2.1.6 are respectively fixedly connected to the upper connecting piece 1.6 of the inner vertical plate and the lower connecting piece 4.9 of the inner vertical plate. Therefore, it can be understood that the inner vertical plate 2.1.6 will not move. The upper end of the outer vertical plate 2.1.1 is fixedly connected to the upper bottom plate 1.1, and the lower end is fixedly connected to the middle horizontal plate 4.8. Since the upper bottom plate is connected to the middle horizontal plate 4.8 through the outer vertical plate 2.1.1 and the upper bottom plate 1.1 is not connected to the upper inner fixing plate 1.2, both the upper bottom plate 1.1 and the middle horizontal plate 4.8 are floating. Therefore, it can be understood that the outer vertical plate 2.1.1 is also movable. Thus, when gas is filled into the cavity, the middle horizontal plate 4.8 can move through the deformation of the lower air diaphragm 4.4, thereby absorbing the vibration interference from below. The outer vertical plate 2.1.1 can move through the deformation of the side air diaphragm 2.1.3, thereby absorbing the vibration interference from the lateral direction. The upper bottom plate 1.1 can move through the deformation of the upper air diaphragm 1.3, thereby absorbing the vibration interference from above. Furthermore, the present application can achieve vibration reduction in multiple directions, so as to adapt to complex usage environments and meet different usage requirements.

[0054] Furthermore, to ensure the relative fixation of the product and the vibration reduction device during product transportation and prevent the product from being damaged due to shaking and collision during transportation, a fixing member 5 is also connected between the outer vertical plate 2.1.1 and the lower bottom plate 4.1. The product and the vibration reduction device are fixed together through the fixing member 5.

[0055] In summary, by setting vibration reduction units in six directions, omnidirectional vibration control is achieved. The vibration reduction units in each direction work independently and cooperate with each other. According to the direction and characteristics of vibration transmission, the vibration energy from different directions is respectively absorbed and isolated, so as to ensure that the product can remain stable in complex working environments and transportation processes, reduce the influence of vibration on the product performance, accuracy and service life, and combine the reliability of passive vibration reduction with the flexibility of active adjustment, which has become an important development direction of modern engineering vibration reduction technology.

[0056] The present invention is not limited solely to what is described in the specification and embodiments. Therefore, for those skilled in the art, additional advantages and modifications can be easily achieved. Thus, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to specific details, representative devices, and the illustrative examples shown and described herein.
