[0034] The driving assembly 110 is used to apply an upward pulling force to the compressor 200 to reduce the pressure of the compressor 100 on the components below it.

[0035] In this embodiment, the air-conditioning outdoor unit includes a shell and a compressor 200. The shell is provided with a driving assembly 110. The compressor 100 is arranged in the shell. An amplitude sensor 230 is provided on the top of the compressor 200. The amplitude sensor 230 is communicatively connected with the driving assembly 110. The driving assembly 110 can apply an upward pulling force to the compressor 200 according to the signal of the amplitude sensor 230 to reduce the pressure of the compressor 100 on the components below it, thereby reducing the transportation stress generated by the air-conditioning outdoor unit during transportation.

[0036] It should be noted that the compressor 200 is arranged inside the outer shell, and a foot pad may be provided between the compressor 200 and the outer shell, or they may be connected and contacted by other means; when a foot pad is provided between the compressor 200 and the outer shell, the drive assembly 110 applies an upward pulling force to the compressor 200, which can reduce the pressure of the compressor 100 on the foot pad below it, on the one hand reducing the transportation stress, and on the other hand allowing the developer to avoid considering the design pain point of the foot pad hardness caused by transportation stress, thereby increasing the optimization space of the foot pad.

[0037] Preferably, the drive assembly 110 is a motor drive control.

[0038] Optionally, the driving assembly 110 is controlled by a spring system or a hydraulic system.

[0039] It can be understood that the solution of this embodiment can help reduce the random vibration stress to which the piping system of the air conditioner outdoor unit is subjected during transportation, and effectively protect the air conditioner outdoor unit piping from fatigue fracture caused by transportation stress.

[0040] Furthermore, in a specific embodiment, the housing includes an outer top cover plate 100 , and at least a portion of the driving assembly 110 is disposed on the outer top cover plate 100 .

[0041] It can be understood that at least a portion of the driving assembly 110 is disposed on the external top cover plate 100 , which can facilitate the disassembly and maintenance of the driving assembly 110 , and effectively increase the convenience of user operation.

[0042] Further, in a specific embodiment, the driving assembly 110 includes:

[0043] Driving mechanism 111;

[0044] A suspension rope 115, the suspension rope 115 is used to connect the compressor 200 to the driving mechanism 111;

[0045] The driving mechanism 111 is used to apply an upward pulling force to the compressor 200 by pulling the suspension rope 115 .

[0046] In this embodiment, the driving assembly 110 includes a driving mechanism 111 and a suspension rope 115. The suspension rope 115 connects the compressor 200 to the driving mechanism 111. When a pulling force needs to be applied to the compressor 200, the driving mechanism 111 can apply an upward pulling force to the compressor 200 by pulling the suspension rope 115, thereby reducing the pressure of the compressor 200 on the components below it.

[0047] It can be understood that the solution of this embodiment is simple, reliable and easy to implement, and can effectively solve the problem of pipeline fatigue fracture of the air-conditioning outdoor unit pipeline caused by transportation stress.

[0048] Furthermore, in a specific embodiment, the air conditioner outdoor unit further includes:

[0049] The hanging ear 210 is arranged on the top of the compressor 200 and is located on the center of gravity of the compressor 200 . The hanging rope 115 is cooperatively connected with the hanging ear 210 .

[0050] In this embodiment, the hanging ear 210 is arranged on the top of the compressor 200 and is located on the center line of gravity of the compressor 200. That is, when the hanging rope 115 applies tension to the compressor 200 by pulling the hanging ear 210, the compressor 200 will not become unstable due to the misalignment of the tension with its center line.

[0051] Preferably, the amplitude sensor 230 is disposed close to the hanging ear 210 , and the amplitude sensor 230 can detect the vibration amplitude of the top of the compressor 200 .

[0052] It can be understood that the solution of this embodiment effectively improves the stability and reliability of the overall structure of the air conditioner outdoor unit.

[0053] Furthermore, in a specific embodiment, the driving mechanism 111 includes:

[0054] The motor 112 is disposed on the outer top cover plate 100, and the motor 112 includes a motor A end 112a and a motor B end 112b that are disposed opposite to each other;

[0055] A rotating shaft 113, two ends of which are respectively connected to the motor A end 112a and the motor B end 112b;

[0056] The suspension rope 115 is wound around and fixed on the surface of the rotating shaft 113 .

[0057] In this embodiment, the driving mechanism 111 includes a motor 112 and a rotating shaft 113, wherein the motor 112 includes a motor A end 112a and a motor B end 112b which are arranged opposite to each other, and the two ends of the rotating shaft 113 are respectively connected with the motor A end 112a and the motor B end 112b; that is, the transmission structure formed by the motor A end 112a, the motor B end 112b and the rotating shaft 113 is fixed on the outer machine top cover 100, and the motor A end 112a and the motor B end 112b are both provided with a driving motor and a signal receiver of the amplitude sensor 230, and the driving motor operation instruction is feedback-regulated by the amplitude sensor. The hanging rope 115 is wound and fixed on the surface of the rotating shaft 113, and the motor 112 drives the rotating shaft 113 to rotate to control the lifting and lowering of the hanging rope 115, thereby controlling the pulling force on the compressor 200.

[0058] It can be understood that the structure of this embodiment effectively improves the stability and reliability of the lifting structure of the driving mechanism 111, and the relatively arranged motor A end 112a and motor B end 112b can provide pulling force while also ensuring the stability of the lifting process.

[0059] Furthermore, in a specific embodiment, the air conditioner outdoor unit further includes:

[0060] The foot pad 220 is disposed between the compressor 200 and the housing.

[0061] It can be understood that the foot pad 220 can reduce the operating noise of the air conditioner outdoor unit, extend its service life, and increase the reliability of the air conditioner outdoor unit.

[0062] Furthermore, this embodiment provides a control method for an air conditioner outdoor unit, the control method is used to control the air conditioner outdoor unit as in any embodiment of the present invention, and the control method includes:

[0063] Obtain the vibration displacement detected by the amplitude sensor;

[0064] According to the vibration displacement, the driving assembly is controlled to apply a pulling force adapted to the vibration displacement to the compressor.

[0065] In this embodiment, the vibration displacement detected by the amplitude sensor is detected. When the vibration displacement is large, the drive component can be controlled to apply a larger pulling force to the compressor, thereby reducing the pressure of the compressor on the components below it, thereby reducing the transportation stress of the compressor; when the vibration displacement is small, the drive component is controlled to apply a smaller pulling force to the compressor, thereby meeting the transportation stress requirement of the compressor.

[0066] It can be understood that the solution of this embodiment proposes a control method for the air-conditioning outdoor unit, which ensures that the driving component can monitor and protect the air-conditioning pipe system in real time under a low-energy and high-efficiency state, and effectively avoids the problem of pipe fatigue and fracture of the air-conditioning outdoor unit pipe caused by transportation stress.

[0067] Further, in a specific embodiment, according to the vibration displacement, controlling the driving assembly to apply a pulling force adapted to the vibration displacement to the compressor includes:

[0068] Compare the vibration displacement with a preset threshold;

[0069] When the vibration displacement is less than or equal to a preset threshold, the pulling force applied by the driving component to the compressor is controlled to be a preset pulling force;

[0070] When the vibration displacement is greater than a preset threshold, the pulling force applied by the driving assembly to the compressor is controlled to increase until the vibration displacement is less than or equal to the preset threshold.

[0071] In this embodiment, when the vibration displacement is less than or equal to the preset threshold value, it means that the vibration displacement is small at this time, and the pulling force applied by the control drive component to the compressor is the preset pulling force; when the vibration displacement is greater than the preset threshold value, it means that the vibration displacement is large at this time, and it is necessary to control the pulling force applied by the control drive component to the compressor to increase until the vibration displacement is less than or equal to the preset threshold value.

[0072] Preferably, when the driving component includes a driving mechanism and a suspension rope, and the driving mechanism includes a motor; when the vibration displacement is less than or equal to a preset threshold value, the preset tension applied by the driving component to the compressor is small, and is only used to keep the suspension rope in a low preload state; when the vibration displacement is greater than the preset threshold value, the tension applied by the driving component to the compressor is controlled to increase until the vibration displacement is less than or equal to the preset threshold value, and the motor stops rotating. At this time, the suspension rope is limited to maintain the current state of the suspension rope.

[0073] It can be understood that the solution of this embodiment can effectively solve the problem of pipeline fatigue fracture of the air conditioner outdoor unit pipeline caused by transportation stress.

[0074] Furthermore, this embodiment provides an air conditioner, which includes an air conditioner outdoor unit as in any embodiment of the present invention.
