In this embodiment, the piston 330 slides in the cavity 321 and is used to change the relative sizes of the first cavity 322 and the second cavity 323, that is, when the piston 330 moves towards the second cavity 323, the volume of the second cavity 323 decreases, the volume of the first cavity 322 increases, and when the piston 330 moves towards the first cavity 322, the volume of the first cavity 322 decreases, and the volume of the second cavity 323 increases.

In this embodiment, the air bag has flexibility, that is, the material of the air bag is a Flexible material, that is, the air bag is a Flexible air bag, and flexibility (Flexible), which can also be interpreted as flexibility, is a physical characteristic in terms of relative rigidity. Flexibility refers to a physical property that an object deforms after being stressed, and the object cannot restore the original shape after the applied force is lost. And after the rigid object is stressed, the shape of the rigid object can be regarded as unchanged in a macroscopic view. In one embodiment, the material of the air bag is rubber, so that the air bag has flexibility.

In one embodiment, the airbag has elasticity, that is, the airbag is made of an elastic material, that is, the airbag is an elastic airbag, so that deformation of the airbag is facilitated, and the airbag has a better buffering effect.

Referring to fig. 1, in the above-mentioned cushion assembly, when the movable seat 200 is stressed and moves in a direction approaching the load bearing seat 110, the volume of the chamber 311 in the air bag 310 is compressed along with the movement of the movable seat 200, the gas in the chamber 311 is transmitted to the first chamber 322 along with the tube 350, and pushes the piston 330 to move in a direction approaching the second chamber 323 and compress the gas in the second chamber 323, and at the same time, the first elastic member 340 is compressed to perform a cushion function, when the stress on the movable seat 200 is removed, the first elastic member 340 recovers, and the volume of the second chamber 323 increases, and pushes the piston 330 to move in a direction approaching the first chamber 322 and pushes the gas in the first chamber 322 into the air bag 310 again, so that the air bag 310 recovers a natural size and is ready for the next cushion. When the movable seat 200 is stressed and moves away from the bearing seat 110, the airbag 310 is stretched along with the movement of the movable seat 200, the volume of the chamber 311 is increased, and simultaneously, the gas in the first cavity 322 is pumped into the chamber 311, so that the piston 330 moves towards the direction close to the first cavity 322, and the volume of the second cavity 323 is increased by the movement of the piston 330, and simultaneously, the first elastic member 340 is stretched to play a role in buffering, when the stress of the movable seat 200 is removed, the first elastic member 340 recovers, and the volume of the second cavity 323 is increased, so that the piston 330 moves away from the first cavity 322, and the gas in the chamber 311 is pumped into the first cavity 322 again, so that the airbag 310 recovers to the natural size, thereby preparing for the next buffering. Because sliding seat 200 is connected with gasbag 310, directly cushion sliding seat 200 through gasbag 310, the gas of cavity 311 advances and discharge gasbag 310 is comparatively level and smooth, can quick deformation unlike the elastic component, and then make sliding seat 200 can be cushioned smoothly, this application has still adopted first elastic component 340 to assist gasbag 310, even make first elastic component 340 and gasbag 310 cooperate, can make gasbag 310 resume the original state smoothly after the buffering, make the cushioning effect of gasbag 310 can go on continuously.

When the test assembly sets up on the sliding seat, can cushion the test assembly through above-mentioned buffering subassembly, reduce the test assembly and receive the vibration and the risk of unable normal work when the transportation. It is worth mentioning that the buffer assembly can be used for buffering the test assembly, and can also be used for other situations requiring buffering.

It is noted that the airbag 310 is shown in a perspective view in fig. 1, with the side wall of the chamber 311 being shown in phantom, i.e. the inner side surface of the airbag 310, and the area within the phantom being the chamber 311.

In this embodiment, the two connecting rods 450 are respectively disposed obliquely to the sliding structure 111, that is, the two connecting rods 450 are oblique to the sliding direction of the sliding block 440. When the movable seat 200 moves towards a direction close to the bearing seat 110, pressure is applied to the connecting plate 410, and when the connecting plate 410 is subjected to the pressure, the two sliding blocks 440 are spread by the connecting rods 450, that is, the connecting plate 410 distributes the pressure to the two sliding blocks 440 by the connecting rods 450, so that the sliding blocks 440 slide along the sliding structure 111, and at this time, the interval between the two sliding blocks 440 is relatively increased, and at this time, the buffer tube 430 extends along with the relative movement of the two sliding blocks 440, and plays a role in buffering. Similarly, as the sliding block 440 is expanded, the connecting rod 450 is also relatively expanded, and the second elastic member 420 is also stressed to be elongated at this time, so as to perform a buffering function, thereby improving the buffering function on the movable seat 200 through the above structure.

It should be understood that, if the damping is achieved by using an elastic member or a damper, the elastic member or the damper is deformed by force, when the force applied to the elastic element or the shock absorber by the buffer object is removed, the elastic element or the shock absorber can quickly recover the shape, so that the elastic force of the elastic piece or the shock absorber can push the buffered object to impact the buffered object, which is not beneficial to the stable motion of the buffered object, the buffering is performed by the above-described interlocking structure, i.e., the auxiliary damping mechanism 400, so that the buffering function can be more smooth, i.e., the cooperation between the structures, the force can be distributed to the components step by step, and when the force on the buffer tube 430 and the second elastic member 420 is removed, the slide 440 and the connecting rod 450 are reset before the connecting plate 410 is reset, therefore, the connecting plate 410 does not impact the movable seat 200, and the buffer of the movable seat 200 is smoother.
