[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] like Figures 1 to 9 As shown, an embodiment of the present invention provides a compressor, which includes a housing 10, a crankshaft 20 and a vibration reduction structure 30, wherein the crankshaft 20 is movably disposed in the housing 10. The vibration reduction structure 30 includes a piston component 31 and a liquid storage cylinder 32, wherein the piston component 31 is mounted on the crankshaft 20, and the liquid storage cylinder 32 is fixedly connected to the inner wall of the housing 10, and the liquid storage cylinder 32 has a liquid storage cavity and a communication port communicating with the liquid storage cavity, wherein the liquid storage cavity is filled with a shear thickening liquid 40, and the piston component 31 is disposed at the communication port, and at least a portion of the piston component 31 is movably disposed in the liquid storage cavity.

[0046] With the compressor provided in this embodiment, during the operation of the compressor, the crankshaft 20 is prone to bending vibration under external loads such as electromagnetic force and centrifugal force. By providing a vibration reduction structure 30, the vibration on the crankshaft 20 is transmitted to the piston component 31, and the vibration of the piston component 31 is consumed and reduced by the action of the shear thickening liquid 40, thereby reducing the vibration of the crankshaft 20, and further reducing the overall vibration noise level of the compressor. Therefore, the compressor provided in this embodiment can solve the problem of high noise caused by compressor vibration in the prior art.

[0047] It should be noted that “at least part of the piston component 31 is movably disposed in the liquid storage cavity” mainly means that at least part of the piston component 31 is movably disposed in the liquid storage cavity. The liquid storage cylinder 32 can be welded to the inner wall of the housing 10 .

[0048] Specifically, a mounting hole adapted to the crankshaft 20 is provided on the piston component 31, and the piston component 31 is sleeved on the crankshaft 20 through the mounting hole. In this way, the piston component 31 can be easily installed, and the vibration on the crankshaft 20 can be stably transmitted to the piston component 31.

[0049] In this embodiment, the piston component 31 includes a mounting portion 313 , a mounting hole is provided on the mounting portion 313 , and the mounting portion 313 is an annular structure.

[0050] Specifically, in one embodiment, the vibration reduction structure 30 further includes a sleeve 33, which is arranged in the mounting hole and sleeved on the crankshaft 20. The crankshaft 20 is provided with an oil hole 21 extending along the length direction of the crankshaft 20, and the crankshaft 20 is also provided with a connecting oil hole 22 penetrating the side wall of the crankshaft 20, one end of the connecting oil hole 22 is connected to the oil hole 21, and the other end of the connecting oil hole 22 is arranged toward the inner ring of the sleeve 33. With such a structural arrangement, the lubricating oil in the oil hole 21 is pumped into the connecting oil hole 22, and the gap between the sleeve 33 and the crankshaft 20 is lubricated through the connecting oil hole 22, which can facilitate the formation of a sliding bearing structure, ensure lubrication of the contact surface between the crankshaft 20 and the sleeve 33, and ensure the normal operation of the compressor. Specifically, the sleeve 33 is interference fit with the mounting hole.

[0051] Specifically, in another embodiment, the vibration reduction structure 30 further includes a rolling bearing 34, which is disposed in the mounting hole and sleeved on the crankshaft 20. In this way, the vibration of the crankshaft 20 can be smoothly transmitted to the piston component 31, and the piston component 31 can move flexibly relative to the crankshaft 20, thereby ensuring the normal operation of the compressor. Specifically, the inner ring of the rolling bearing 34 is interference fit with the crankshaft 20, and the outer ring of the rolling bearing 34 is interference fit with the mounting hole.

[0052] In this embodiment, the piston component 31 includes a piston rod 311 and a piston head 312 connected to each other, the piston rod 311 is movably arranged at the communication port, and the piston head 312 is movably arranged in the liquid storage chamber. Specifically, the cross-sectional area of ​​the piston head 312 is larger than the cross-sectional area of ​​the piston rod 311, and the piston component 31 moves along the extension direction of the piston rod 311.

[0053] The piston head 312 is spaced from the inner wall of the liquid storage chamber to ensure that the piston head 312 can move smoothly in the liquid storage chamber. Specifically, when the piston head 312 moves, the thickened shear fluid is squeezed and sheared at the same time, and shear thickening occurs to dissipate energy.

[0054] In this embodiment, the vibration reduction structure 30 further includes a sealing member 35, which is installed at the communication port and located at the gap between the communication port and the piston rod 311. In this way, the shear thickening liquid 40 in the liquid storage chamber can be prevented from leaking through the gap between the communication port and the piston rod 311, thereby improving the sealing performance of the liquid storage chamber, so as to ensure that the shear thickening liquid 40 can stably interact with the piston rod 311.

[0055] Specifically, the sealing member 35 may be a sealing ring, and the sealing member 35 may be made of a flexible material.

[0056] Specifically, the liquid storage cylinder 32 can be set to an annular structure, and the liquid storage cylinder 32 is a symmetrical structure along the symmetry axis of the crankshaft 20, so that it is easy to improve the vibration reduction and noise reduction effect.

[0057] “The liquid reservoir 32 is a structure symmetrical along the symmetry axis of the crankshaft 20” can be understood as the liquid reservoir 32 is symmetrically arranged along the symmetry axis of the portion of the crankshaft 20 corresponding to the portion where the liquid reservoir 32 is mounted, and the portion of the crankshaft 20 corresponding to the portion where the liquid reservoir 32 is mounted can be a circular cross-section. Preferably, the liquid reservoir 32 is symmetrically arranged along the symmetry axis of the portion of the crankshaft 20 corresponding to the portion where the liquid reservoir 32 is mounted.

[0058] Alternatively, there are multiple liquid storage cylinders 32, and the piston component 31 includes multiple piston members, and the multiple piston members are arranged one-to-one with the multiple liquid storage cylinders 32, and at least part of each piston member is movably arranged in the liquid storage cavity of the corresponding liquid storage cylinder 32, and the multiple liquid storage cylinders 32 are arranged at intervals along the circumference of the crankshaft 20. In this way, it is convenient to effectively improve the vibration reduction and noise reduction effect by arranging multiple liquid storage cylinders 32. Preferably, the liquid storage cylinders 32 can be an even number and arranged in pairs, and each pair of liquid storage cylinders 32 includes two liquid storage cylinders 32 arranged oppositely.

[0059] Alternatively, there are multiple liquid storage cylinders 32, and the piston component 31 includes multiple piston members, and the multiple piston members are arranged one-to-one with the multiple liquid storage cylinders 32, and at least part of each piston member is movably arranged in the liquid storage cavity corresponding to the liquid storage cylinder 32, and the multiple liquid storage cylinders 32 are arranged at intervals along the circumference of the crankshaft 20, and the multiple liquid storage cylinders 32 are symmetrically arranged along the symmetry axis of the crankshaft 20. In this way, the vibration reduction and noise reduction effect of the crankshaft 20 can be better improved through the symmetrical arrangement of the multiple liquid storage cylinders 32.

[0060] Specifically, each piston member includes a piston rod 311 and a piston head 312 which are connected to each other.

[0061] In this embodiment, the vibration reduction structure 30 is provided with an avoidance channel which passes through the top and bottom of the vibration reduction structure 30 , so that the fluid in the shell 10 can flow smoothly through the avoidance channel, thereby avoiding the situation in which the fluid in the shell 10 is blocked and cannot flow smoothly.

[0062] Specifically, there are multiple vibration reduction structures 30, and the multiple vibration reduction structures 30 are arranged at intervals along the height direction of the crankshaft 20, so that it is convenient to better improve the vibration reduction effect on the crankshaft 20. Specifically, there can be three vibration reduction structures 30, two of the three vibration reduction structures 30 are respectively arranged at the two ends of the crankshaft 20, and the remaining one of the three vibration reduction structures 30 is located in the middle of the crankshaft 20.

[0063] Specifically, the compressor further includes a pump body 50, which is disposed on the crankshaft 20. In order to better improve the vibration reduction structure 30, the vibration reduction structure 30 can be disposed at a position where the vibration of the pump body 50 is greater in combination with the modal simulation or test results of the compressor, and the vibration reduction structure 30 can be disposed to be symmetrical with respect to the symmetrical structure center of the crankshaft 20.

[0064] Specifically, the liquid storage cylinder 32 can be set to be multiple, the piston component 31 includes multiple piston parts, the multiple piston parts are arranged one-to-one with the multiple liquid storage cylinders 32, at least part of each piston part is movably arranged in the liquid storage cavity of the corresponding liquid storage cylinder 32, and the multiple liquid storage cylinders 32 are arranged at intervals along the circumference of the crankshaft 20 to form an avoidance channel; the vibration damping structure 30 also includes an annular mounting shell 36, the outer ring of the annular mounting shell 36 is connected to the inner wall of the shell 10.

[0065] Specifically, the annular mounting shell 36 can be fixed to the inner wall of the housing 10 by using a shrink fit process or welding.

[0066] like Figure 3 As shown, the end of the liquid storage cylinder 32 away from the communication port is an open end, and the liquid storage cylinder 32 is connected to the inner ring of the annular mounting shell 36, and the inner ring of the annular mounting shell 36 is sealed at the open end. With such a structural arrangement, the installation of the vibration reduction structure 30 can be facilitated.

[0067] like Figure 8 As shown, the end of the liquid storage cylinder 32 away from the communication port is a blocking shell end, and the blocking shell end is connected to the inner circle of the annular mounting shell 36. In this way, the number of liquid storage cylinders 32 can be flexibly adjusted and set according to actual conditions, and the installation of the vibration reduction structure 30 can also be facilitated.

[0068] like Figures 4 to 6As shown, the liquid storage cylinder 32 is an annular structure, the piston component 31 is an annular structure, and the vibration reduction structure 30 further includes a connecting member 37, one end of the connecting member 37 is connected to the inner wall of the housing 10, and the other end of the connecting member 37 is connected to the liquid storage cylinder 32. There are at least two connecting members 37, and at least two connecting members 37 are arranged at intervals to form an avoidance channel. With such a structural arrangement, it is easy to install the vibration reduction structure 30, and it is also possible to avoid the vibration reduction structure 30 blocking the inside of the housing 10, thereby ensuring the smooth flow of the fluid inside the housing 10 and ensuring that the compressed gas in the housing 10 can be smoothly discharged from the exhaust port above the housing 10.

[0069] Specifically, the connecting piece 37 may be welded to the inner wall of the housing 10 .

[0070] Specifically, the shear thickening liquid 40 includes polyvinyl alcohol liquid and silica gel particles, so that it is convenient to better damp the piston component 31, so as to better reduce vibration and noise, and reduce the overall vibration noise of the compressor. Specifically, the shear thickening liquid 40 generally includes a dispersed phase and a dispersed medium. The substance contains a large amount of hard nano-scale silica gel particles suspended in a non-toxic polyvinyl alcohol fluid. Silicon carbide is added to polyethylene glycol to prepare the liquid.
