To achieve the above object, the present invention proposes a supporting device, as shown in fig. 1, which, in a first embodiment, comprises: at least two support assemblies 2, each support assembly 2 includes a cylinder 21 and a support member, the support member includes a support portion (not shown) and an adjusting portion (not shown), the support portion is exposed out of the cylinder 21, the adjusting portion is located in the cylinder 21 and divides the cylinder 21 into a first compression cavity 22 and a second compression cavity 23 (as shown in fig. 2 and 3), and the first compression cavity 22 and the second compression cavity 23 are filled with a compression medium (not shown) to support the adjusting portion; an adjustment assembly connected to the first and second compression chambers 22 and 23 to adjust the pressure of the compressed medium in the first and second compression chambers 22 and 23; the detection piece is arranged on the adjusting assembly to detect the pressure value or the flow value of the adjusting assembly, and/or the detection piece is arranged on the supporting part to detect the pressure value of the supporting part; the controller is connected with the adjusting component and the detecting piece and is used for controlling the adjusting component to adjust the pressure of the compressed medium in the first compression cavity 22 and the second compression cavity 23 according to the pressure value or the flow value detected by the detecting piece.
The supporting object of the supporting device provided by the invention is an object which can generate vibration or incline, such as a motor or a compressor 10 of an air conditioner, the supporting object is arranged on the supporting part of the supporting part to form connection with the supporting part, and the connection can be fixed connection, such as clamping connection, threaded connection, screw fixation and the like. The vibration or inclination of the supporting object itself generates a pressure or a tensile force on the supporting member, which acts on the adjusting portion, causing the adjusting portion to move to change the pressure in the first compression chamber 22 or the second compression chamber 23.
The supporting device is formed by two or more supporting components connected with each other through an adjusting component, fig. 6 shows a schematic view that three supporting components (a first supporting component 2a, a second supporting component 2b, and a third supporting component 2c) are connected with each other through an adjusting component, each supporting component 2 includes a cylinder 21 and a supporting member, as shown in fig. 2, the supporting member is disposed on the cylinder 21, the supporting member can be divided into a supporting portion and an adjusting portion, the supporting portion is exposed out of the cylinder 21 and is used for being connected with a supporting object (as shown in fig. 5, the supporting portion is connected with the compressor base 11), the adjusting portion is located in the cylinder 21 and divides the cylinder 21 into a first compression cavity 22 and a second compression cavity 23 (as shown in fig. 3), the first compression cavity 22 and the second compression cavity 23 are filled with a compression medium, the adjusting component is connected between the first compression cavity 22 and the second compression cavity 23 of different cylinders 21, so that the first compression chamber 22 and the second compression chamber 23 communicated through the adjusting assembly can communicate with each other with compressed media, the adjusting assembly includes a connection pipe 31 and a flow rate adjusting member, the connection pipe 31 is connected between the first compression chamber 22 and the second compression chamber 23 of different cylinders 21, each first compression chamber 22 is connected with at least one second compression chamber 23 so that the compressed media in the first compression chamber 22 can flow out, and similarly, each second compression chamber 23 is also communicated with at least one first compression chamber 22 so that the compressed media in the second compression chamber 23 can flow out.
As shown in fig. 3, the supporting member specifically includes a supporting rod 24 and a piston 25, the supporting portion and the adjusting portion are respectively located at two ends of the supporting rod 24, and the piston 25 is mounted on the adjusting portion and divides the corresponding cylinder 21 into a first compression chamber 22 and a second compression chamber 23. The piston 25 abuts against the inner wall of the cylinder 21 to partition the cylinder 21 into the first compression chamber 22 and the second compression chamber 23, and the piston 25 expands and contracts in the cylinder 21 by a tensile force or a pressure of a support object, and this expansion and contraction movement causes a change in pressure of a compression medium in the first compression chamber 22 and the second compression chamber 23, so that the piston can flow in the first compression chamber 22 and the second compression chamber 23 which are communicated with each other, and the entire support device can return to a balance.
Since the tension or pressure generated by the supporting object is transmitted from the supporting part to the adjusting part, and the pressure in the first compression chamber 22 and the second compression chamber 23 changes, the tension or pressure change signal of the supporting part can be obtained when the detecting part detects the adjusting component or the supporting part, and therefore, the detecting part can be arranged on the supporting part or the adjusting component. The detection piece can be a pressure sensor, the pressure sensor can be arranged on the supporting part or the adjusting assembly to detect the pressure on the supporting part, and can also detect the pressure generated by the compressed medium in the adjusting assembly, and the larger the flow of the compressed medium in the adjusting assembly is, the larger the generated pressure is. Of course, the pressure change of the supporting object can also be obtained by detecting the flow rate of the compressed medium in the regulating assembly, and in this case, the detecting element is a flowmeter. The output end of the detection piece is connected with the controller, and outputs a detection signal (a pressure value or a flow value) to the controller, and when the detection signal contains information that the pressure value or the flow value is too large, the controller controls the regulating component to regulate the pressure of the compressed media in the first compression cavity 22 and the second compression cavity 23.
In this embodiment, the supporting device has three supporting components 2 as an example, as shown in fig. 6, the three supporting components 2 are named as a first supporting component 2a, a second supporting component 2b, and a third supporting component 2c, respectively, the supporting portion of the first supporting component 2a, the supporting portion of the second supporting component 2b, and the supporting portion of the third supporting component 2c are connected to three positions at the bottom of the supporting object, respectively, and when the supporting object vibrates or inclines and deviates from a stable state, some of the three supporting components 2 are necessarily subjected to tension or pressure. Assuming that the first supporting component 2a is under tension, and the second supporting component 2b and the third supporting component 2c are under pressure, the supporting portion of the first supporting component 2a is stretched, so that the pressure in the second compression cavity 23 of the first supporting component 2a changes, which causes the compressed medium in the second compression cavity 23 of the first cylinder to flow into the two first compression cavities 22 communicated with the second compression cavity 23 (the first compression cavity 22 corresponding to the second supporting component 2b and the first compression cavity 22 corresponding to the third supporting component 2c), the pressure value or flow value detected by the detecting element increases, and the controller controls the adjusting component to reduce the pressure in the second compression cavity 23 of the first supporting component 2 a.

In an embodiment, the flow regulating member includes at least one of a solenoid valve and an accumulator, when the flow regulating member includes only the solenoid valve, the solenoid valve is installed on the connection pipe 31, because the same cylinder is under tension or pressure, the first compression chamber 22 and the second compression chamber 23 on the same cylinder both have pressure changes, therefore, the solenoid valve can be installed on the connection pipe 31 where the first compression chamber 22 and the second compression chamber 23 of the same cylinder are communicated, the controller is electrically connected with the solenoid valve, the speed of the return balance can be increased, and the solenoid valve magnetism can be one or more. When the flow rate adjusting member only comprises an energy accumulator, the first compression cavity 22 and the second compression cavity 23 of the same cylinder body can be respectively connected to two different energy accumulators (for example, the first compression cavity 22 of the support assembly 2c in fig. 6 is communicated to the first energy accumulator 32, and the second compression cavity 23 is communicated to the second energy accumulator 33), when the pressure in the first compression cavity 22 becomes high, the controller controls the energy accumulator to add a compression medium to the first compression cavity 22, the compression medium in the second compression cavity 23 of the same cylinder body as the first compression cavity 22 is stored in the energy accumulator, and when the pressure in the first compression cavity 22 is low, the controller controls the energy accumulator to be opened to receive the compression medium from the first compression cavity 22.
