[0026] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present application and are not intended to limit the protection scope of the present application.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The compressor is the core power source of the air conditioner and also the main source of vibration and noise of the air conditioner. In order to improve the user experience and reduce the transmission of compressor vibration to the outside of the air conditioner, it is necessary to isolate the vibration of the compressor.

[0030] In the related art, the compressor is isolated from vibration by installing a foot pad between the compressor and the outer machine chassis. For example, a spring rubber pad or a rubber foot pad. The lower the stiffness of the foot pad, the better the vibration isolation effect.

[0031] However, if the stiffness of the foot pad is too low, during the handling and transportation of the air conditioner, the vibration displacement generated by the compressor is relatively large, which may cause the compressor pipeline to break; if the stiffness of the foot pad is too high, the vibration isolation effect is poor and the noise of the compressor is relatively large.

[0032] The vibration isolation device, outdoor unit of the air conditioner, and air conditioner provided by this application can actively adjust the pressure of the air spring according to the vibration frequency of the target device, thereby adjusting the stiffness of the air spring, and can avoid the stiffness of the vibration isolation device being too low or too high.

[0033] In the first aspect, this application provides a vibration isolation device, which is arranged at the bottom of the target device. For example, the vibration isolation device is arranged at the bottom of the compressor.

[0034] Combined Figure 1 As shown, the vibration isolation device provided by this application includes an air spring 100, a cylinder 200, and a control component 300.

[0035] The air spring 100 is arranged at the bottom of the target device.

[0036] The cylinder 200 includes an air chamber 201 and an actuator 202, and the air chamber 201 is communicated with the air spring 100.

[0037] The control component 300 can control the movement of the actuator 202 according to the vibration frequency of the target device, change the volume of the air chamber 201, thereby changing the pressure of the air spring 100, and the stiffness of the air spring 100 can be changed by changing the pressure of the air spring 100.

[0038] On the premise of adopting the above technical solution, the vibration isolation device provided by the present application includes an air spring 100, a cylinder 200, and a control component 300. The air spring 100 is arranged at the bottom of the target device and can isolate the vibration of the target device, effectively reducing the transmission of the vibration of the target device to the outside. The air chamber 201 of the cylinder 200 is communicated with the air spring 100, and the control component 300 can control the movement of the actuator 202 according to the vibration frequency of the target device, change the volume of the air chamber 201, and thus change the pressure of the air spring 100. In this way, the present application can actively adjust the pressure of the air spring 100 according to the vibration frequency of the target device, thereby adjusting the stiffness of the air spring 100. The stiffness of the air spring 100 is adapted to the vibration frequency of the target device, which can avoid the stiffness of the vibration isolation device being too low or too high.

[0039] Regarding the air spring 100.

[0040] The air spring, also known as an airbag spring or a gas spring, is a spring that uses gas as an elastic medium. The air spring adjusts the supporting force and stiffness based on the pressure change of the compressed gas in a closed container. The air spring fills an inert gas or an oil-gas mixture in a closed pressure cylinder, making the pressure in the cavity several times or dozens of times higher than the atmospheric pressure. When it is necessary to increase the supporting force or stiffness, the pressure can be increased by compressing the gas, thereby enhancing the supporting force and stiffness; on the contrary, when it is necessary to reduce the supporting force or stiffness, the pressure can be reduced by increasing the gas volume.

[0041] Combined with Figure 2 As shown, the air spring 100 includes an airbag 101 and an upper mounting plate 102 and a lower mounting plate 103 arranged on the upper and lower sides of the airbag 101. The upper mounting plate 102 extends outward from the airbag 101 to form an upper mounting edge 1021, and a plurality of first fixing holes 1022 are arranged on the upper mounting edge 1021. The lower mounting plate 103 extends outward from the airbag 101 to form a lower mounting edge 1031, and a plurality of second fixing holes 1032 are arranged on the lower mounting edge 1031. By arranging the upper mounting plate 102, the force on the contact surface between the air spring and the target device can be made more uniform, and at the same time, it is convenient to fixedly connect with the target device. By arranging the lower mounting plate 103, the force at the bottom of the airbag can be made more uniform, and at the same time, it is convenient to fix the air spring 100 to the base to be installed, preventing the air spring 100 from shifting.

[0042] Optionally, combined with Figure 2As shown, the upper mounting plate 102 is set as a triangular plate. The upper mounting plate 102 includes three first fixing holes 1022, and the three first fixing holes 1022 are respectively arranged at the three vertex angles of the triangular plate. In this way, it can not only ensure the connection strength and stability between the upper mounting plate 102 and the target device, but also reduce the space occupied by the upper mounting plate 102 and avoid interfering with other structures. The lower mounting plate 103 is set as a triangular plate. The lower mounting plate 103 includes three second fixing holes 1032, and the three second fixing holes 1032 are respectively arranged at the three vertex angles of the triangular plate. In this way, it can not only ensure the connection strength and stability between the upper mounting plate 102 and the target device, but also reduce the space occupied by the upper mounting plate 102 and avoid interfering with other structures.

[0043] For the air cylinder 200.

[0044] In some embodiments, in combination with Figure 1 As shown, the air cylinder 200 includes an accommodation cavity 203. The actuator 202 includes a telescopic rod 2021 and a piston 2022. The piston 2022 is arranged in the accommodation cavity 203. The piston 2022 divides the accommodation cavity into an air chamber 201 and an actuator chamber 204. The telescopic rod 2021 is arranged in the actuator chamber 204, and the telescopic rod 2021 can telescopically move to drive the piston 2022 to move.

[0045] By telescoping the telescopic rod 2021 along its axial direction, the piston 2022 can be driven to move, changing the volume of the air chamber 201, thereby changing the pressure of the air spring 100. Specifically, when the telescopic rod 2021 extends, it can drive the piston 2022 to move towards the direction close to the air chamber 201, thereby reducing the volume of the air chamber 201. The gas in the air chamber 201 and the compression spring 100 is compressed, and the pressure of the air spring 100 increases; when the telescopic rod 2021 shortens, it can drive the piston 2022 to move away from the air chamber 201, thereby increasing the volume of the air chamber 201. The gas in the air chamber 201 and the compression spring 100 expands, and the pressure of the air spring 100 decreases.

[0046] In some embodiments, the actuator 202 is a voice coil actuator. A voice coil actuator is an actuator device based on the electromagnetic principle. It drives the load through the force of the coil moving in the magnetic field, and has the advantages of compact structure, low energy consumption, sensitive response, no lubrication, wide adaptability frequency band, large displacement and output force, etc. When the coil of the voice coil actuator is energized, the coil will move under the action of the Ampere force in the magnetic field, thereby driving the load to move. By changing the magnitude and direction of the current in the coil, the moving distance and direction of the actuator 202 can be controlled.

[0047] For the control component 300.

[0048] In some embodiments, in combination with Figure 1As shown, the control component 300 includes a vibration sensor 301, a signal collector 302, and a controller 303. The vibration sensor 301 is used to detect the vibration frequency of the target device and generate a vibration signal. The signal collector 302 is connected to the vibration sensor 301, and the signal collector 302 is used to collect the vibration signal. The controller 303 is used to receive the vibration signal sent by the signal collector and control the movement of the actuator 202 according to the vibration signal.

[0049] The vibration sensor 301 is responsible for real-time monitoring of the vibration condition of the target device. It can convert the vibration frequency generated by the target device into a measurable and processable vibration signal. The signal collector 302 is directly connected to the vibration sensor 301 and is responsible for receiving the vibration signal output by the vibration sensor 301. After processing the vibration signal, the signal collector sends it to the controller 303. The controller 303 receives the vibration signal from the signal collector 302 and processes it according to a preset logic or algorithm, so as to control the movement of the actuator 202 in real time according to the vibration signal and adjust the stiffness of the air cylinder 200.

[0050] In some embodiments, the vibration sensor 301 is disposed at the bottom of the target device. The bottom of the target device is in direct contact with the vibration isolation device. By disposing the vibration sensor 301 at the bottom of the target device, the detection of the vibration frequency is more accurate, and the vibration isolation device can be better utilized to isolate vibration for the target device.

[0051] In some embodiments, in combination Figure 1 As shown, the control component 300 further includes a power amplifier 304. The power amplifier 304 is disposed between the controller 303 and the actuator 202. The power amplifier 304 serves as a bridge connecting the controller 303 and the actuator 202. The power amplifier 304 receives the control signal from the controller 303, amplifies the control signal, and then transmits it to the actuator 202. In this way, the actuator 202 can move according to the amplified control signal to adjust the stiffness of the air spring, so as to achieve the purpose of vibration isolation.

[0052] In some embodiments, in combination Figure 1 As shown, the vibration isolation device further includes an air pipeline 400. The first end of the air pipeline 400 is communicated with the air spring 100, and the second end of the air pipeline 400 is communicated with the air chamber 201. The air pipeline 400 can communicate the air spring 100 with the air chamber 201 of the air cylinder 200, so as to facilitate adjusting the stiffness of the air spring 100 by adjusting the volume of the air chamber 201. Specifically, the amount of the gas filled in the air chamber 201 and the air cylinder 200 is a fixed value. When the volume of the air chamber 201 decreases, the filled gas is compressed, and the stiffness of the air spring 100 increases; when the volume of the air chamber 201 increases, the filled gas expands, and the stiffness of the air spring 100 decreases.

[0053] In a second aspect, the present application provides an outdoor unit of an air conditioner.

[0054] Combined with Figure 3 and Figure 4 As shown, the outdoor unit of the air conditioner provided by the present application includes an outdoor unit housing, a compressor 500, and the above-mentioned vibration isolation device. The outdoor unit housing includes a chassis 600. The compressor 500 is disposed in the outdoor unit housing. The air spring 100 of the vibration isolation device is disposed between the chassis 600 and the compressor 500.

[0055] On the premise of adopting the above technical solution, the outdoor unit of the air conditioner provided by the present application is equipped with a vibration isolation device, which includes an air spring 100, a cylinder 200, and a control component 300. The air spring 100 is disposed at the bottom of the compressor 500 and can isolate vibration of the compressor 500, effectively reducing the transmission of the vibration of the compressor 500 to the outside. The air chamber 201 of the cylinder 200 is communicated with the air spring 100, and the control component 300 can control the movement of the actuator 202 according to the vibration frequency of the compressor 500, change the volume of the air chamber 201, and thus change the pressure of the air spring 100. In this way, the present application can actively adjust the pressure of the air spring 100 according to the vibration frequency of the compressor 500, thereby adjusting the stiffness of the air spring 100. The stiffness of the air spring 100 is adapted to the vibration frequency of the compressor 500, which can avoid the stiffness of the vibration isolation device being too low or too high, effectively isolate vibration, reduce the vibration and noise of the outdoor unit of the air conditioner, and can avoid large vibration displacement of the compressor during handling due to the too low stiffness of the vibration isolation device, which is beneficial to protecting the compressor.

[0056] In some embodiments, the vibration isolation device is fixedly connected to the compressor 500 by bolts, and the vibration isolation device is fixedly connected to the chassis 600 by bolts. The bolted connection is firm and reliable and easy to implement.

[0057] The air spring 100 includes an upper mounting plate and a lower mounting plate.

The air chamber 201 of the cylinder 200 is communicated with the air spring 100. The control component 300 can control the movement of the actuator 202 according to the vibration frequency of the compressor 500, change the volume of the air chamber 201, and thus change the pressure of the air spring 100. In this way, this application can actively adjust the pressure of the air spring 100 according to the vibration frequency of the compressor 500, thereby adjusting the stiffness of the air spring 100. The stiffness of the air spring 100 is adapted to the vibration frequency of the compressor 500, which can avoid the stiffness of the vibration isolation device being too low or too high.
