The cushion pad 200 made of EVA plastic has a long life span and can sufficiently absorb vibration generated from the adsorption tray 100.

In addition, in this embodiment, the position of the cushion pad 200 far away from the adsorption port 110 is further overlapped with the fixing block 300, the cushion pad 200 and the fixing block 300 are overlapped to form the vibration damping device 400, the fixing block 300 can abut against the cushion pad 200, the cushion pad 200 can be attached to the back of the adsorption disc 100 to the greatest extent, and therefore the amplitude of the adsorption disc 100 can be reduced more sufficiently. Of course, in other embodiments, the fixing block 300 may not be provided, and only the cushion 200 may be provided.

In addition, in the present embodiment, the buffer pads 200 and the fixing blocks 300 of the vibration damping device 400 are detachably connected by bolts, so that the buffer pads 200 or the fixing blocks 300 can be separately replaced, which is beneficial to the later maintenance of the noise reduction glass sucker 001. Specifically, in the present embodiment, the through hole 410 is formed in the vibration damping device 400, and the through hole 410 penetrates through the vibration damping device 400 along the axial direction of the vibration damping device 400, so that the bolt can be inserted into the through hole 410, and then the two ends of the bolt are provided with the nuts, which are matched with each other, and the bolt and the nuts act together, so that the cushion pad 200 and the fixing block 300 are detachably connected. Of course, in some other embodiments, structures such as a card slot and a buckle may also be adopted to achieve the purpose of detachable connection, and details are not described herein again. The fixing block 300 in this embodiment is generally a nylon block. The nylon block has good rigidity and wear resistance, and the nylon block is used as the fixing block 300, so that the cushion pad 200 can be well fixed.

In this embodiment, the back surface of the adsorption plate 100 is further communicated with a communicating air pipe 500, the communicating air pipe 500 penetrates through the vibration damping device 400, the end, far away from the adsorption plate 100, of the communicating air pipe 500 is further communicated with an air valve 510, and the air valve 510 can play a role in air suction and ventilation, so that when the noise reduction glass suction cup 001 works in the embodiment, air suction or ventilation can be performed as required, so that a vacuum area is formed between the adsorption plate 100 and glass or the vacuum area disappears.

In addition, in the present embodiment, the stopper 600 is fitted over the outer surface of the communication air pipe 500, and the stopper 600 abuts against the vibration damping device 400 to apply a force to the vibration damping device 400 to approach the adsorption plate 100, thereby achieving an effect of restricting the vibration of the vibration damping device 400. Through the cooperation of stop device 600 and damping device 400, can make blotter 200 more laminate adsorption disc 100, reduce the noise that noise reduction glass sucking disc 001 produced when working better. In other embodiments, if the fixing block 300 is not superimposed on the cushion 200, the stopper 600 directly abuts against the cushion 200.

Illustratively, the stopper 600 in this embodiment includes an elastic member 610 and an abutting member 620 fixed to the outer surface of the communicating air tube 500, the elastic member 610 is located between the abutting member 620 and the vibration damping device 400, and both ends of the elastic member 610 are abutted against the vibration damping device 400 and the abutting member 620, respectively.

At this time, the abutting part 620 and the elastic part 610 work together to provide pressure for the vibration damping device 400, so as to ensure that the cushion pad 200 can be better attached to the adsorption disc 100. Moreover, the elastic member 610 can also play a role in buffering, so that the damage probability of the noise reduction glass sucker 001 is reduced.

The specific working process of the noise reduction glass sucker 001 in the embodiment is as follows:

when automobile glass is to be installed, the front face of the horn-shaped adsorption disc 100 is attached to the glass, air is exhausted through the air valve 510, air in the area formed by surrounding between the adsorption disc 100 and the glass can be exhausted through the communicating air pipe 500, vacuum can be gradually formed between the adsorption disc 100 and the glass, the adsorption disc 100 can be closely attached to the glass under the action of atmospheric pressure, and therefore when the adsorption disc 100 is moved, the glass can move together, and the windshield is moved to the installation position and is installed.

After the installation is completed, the air valve 510 will vent the area between the adsorption plate 100 and the glass through the communication air pipe 500, and the vacuum area between the adsorption plate 100 and the glass disappears, so that the adsorption plate 100 can be completely detached from the glass.

In the process of ventilating, because the back of adsorption disc 100 is covered with the material and is the blotter 200 of EVA plastics, it can play the cushioning effect well, reduces the vibration range of adsorption disc 100, just so adsorption disc 100 is difficult to send very big noise. The fixing block 300 and the stopper 600 on the cushion 200 can apply a force against the adsorption disc 100 to the cushion 200 to ensure that the cushion 200 is completely attached to the adsorption disc 100. But also the amount of force applied can be adjusted by adjusting the position of the nut 621 from the cushion pad 200.

Experiments show that when the noise reduction glass sucker 001 of the embodiment is detached from the glass, the sound volume of the emitted noise can be reduced to less than 69.4dB at a position away from the noise reduction glass sucker 001. When the existing glass sucker falls off from glass, the noise volume emitted by the glass sucker at a position 1m away from the glass sucker is above 96.2 dB.
