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 support portions (not shown) and adjusting portions (not shown) respectively located at two ends of the support member, the support portions are exposed out of the cylinder 21, the adjusting portions are located in the cylinder 21 and divide the cylinder 21 into a first compression cavity 22 and a second compression cavity 23 (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), so that the support member can extend and retract under the action of the compression medium; and the adjusting piece is connected between the first compression cavity 22 and the second compression cavity 23 of different cylinders to form a linkage adjusting structure so as to adjust the pressure of the compression medium in the first compression cavity 22 and the second compression cavity 23 to reach an equilibrium state.
The supporting device provided by the invention is used for supporting an object which can generate vibration or incline, such as a motor or a compressor 10 of an air conditioner, a supporting object is arranged on a supporting part of a supporting piece 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 support object itself generates a pressure or tension on the support, which provides the motive force for the telescopic movement of the support.
The supporting device is composed of two or more than two, for example, three (as shown in fig. 6 and 8), four (as shown in fig. 9 and 12), and the like, each supporting assembly 2 includes a cylinder 21 and a supporting member, the supporting member is disposed on the cylinder 21, the supporting member is divided into a supporting portion and an adjusting portion, the supporting portion is exposed out of the cylinder 21 and is used for connecting with a supporting object (as shown in fig. 5, the supporting portion is connected with the compressor base 11), the adjusting portion is disposed 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 member is connected between the first compression cavity 22 and the second compression cavity 23 of different cylinders 21, so that the first compression cavity 22 and the second compression cavity 23 communicated through the adjusting member can flow the compression medium mutually, the adjusting member can be a connecting pipe, the connecting pipes are connected between the first compression chambers 22 and the second compression chambers 23 of different cylinders 21, each first compression chamber 22 is connected with at least one second compression chamber 23 so that the compressed medium in the first compression chamber 22 can flow out, and similarly, each second compression chamber 23 is also connected with at least one first compression chamber 22 so that the compressed medium in the second compression chamber 23 can flow out.
There are various cases of the connection between the first compression chamber 22 and the second compression chamber 23: the number of the adjusting parts is equal to that of the supporting assemblies 2, in this case, only one adjusting part is used for communicating the adjacent first compression cavity 22 and the second compression cavity 23 between two adjacent cylinder bodies 21, that is, all the cylinder bodies 21 are mutually connected in series to form a circulation loop for circulating the compression medium, so that the plurality of supporting assemblies 2 can realize combined adjustment; in another case, the number of the adjusting members is larger than that of the support assembly 2 (as shown in fig. 6, 8, 9 and 12, the dashed lines in fig. 8 and 9 are electric wires), each first compression chamber 22 can be communicated with a plurality of second compression chambers 23 through the adjusting members (except for the second compression chamber 23 in the same cylinder 21 as the first compression chamber 22), and similarly, the second compression chambers 23 can be communicated with a plurality of first compression chambers 22 through the adjusting members (except for the first compression chamber 22 in the same cylinder 21 as the second compression chamber 23), in which case, when the pressure of the medium in the first compression chamber 22 or the second compression chamber 23 changes, the compressed medium can flow out from a plurality of flow paths, and the adjustment is more rapid.
In this embodiment, the supporting device is exemplified by having three supporting components 2, the three supporting components 2 are named as a first supporting component 2a, a second supporting component 2b and a third supporting component 2c, the first supporting component, the second supporting component and the third supporting component are respectively connected to three positions at the bottom of the supporting object, when the supporting object vibrates or inclines and deviates from a stable state, the three supporting components 2 are necessarily subjected to tension and pressure, assuming that the first supporting component 2a is subjected to tension, the second supporting component 2b and the third supporting component 2c are subjected to pressure, the first supporting component is stretched, so that the pressure in the second compression cavity 23 of the first supporting component 2a changes, resulting in the compressed medium in the second compression cavity 23 of the first cylinder flowing 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 2 c), the pressure in the two first compression cavities 22 is increased, the adjusting end of the second support component 2b and the adjusting end of the third support component 2c both move towards the second compression cavity 23 under the pushing of the pressure, so that the volume of the second compression cavity 23 is reduced, the volume of the first compression cavity 22 is increased, the positions of the second support component 2b and the third support component 2c fixed on the support object are raised, the second compression cavity 23 in the second support component 2b and the second compression cavity 23 in the third support component 2c are reduced due to the volume reduction, the compression medium can further flow into the first compression cavity 22 in the first support component 2a, and therefore the compression medium of the first compression cavity 22 in the first cylinder is supplemented. In this way, the compression medium of the entire adjustment device is not changed, each support member 2 is restored to the equilibrium state, the vibration or inclination of the support object is adjusted, the stability is ensured, and the generation of vibration noise of the compressor 10 is also suppressed.
It should be noted that the above-mentioned process is only a transient equilibrium state, and in fact, the vibration of the compressor 10 pulls up the first supporting member 2a during the above-mentioned rising process, and pushes down the first supporting member 2a after the transient, as shown in fig. 6, and the flow process of the compression medium is just reversed: when the first support member 2a is subjected to a downward pressure, the compressed medium in the first compression chamber 22 of the first support member 2a flows into the second compression chamber 23 in the second support member 2b and the second compression chamber 23 in the third support member 2c, and the compressed medium in the second compression chamber 23 in the second support member 2b and the first compression chamber 23 in the third support member 2c flows into the second compression chamber 23 of the first support member 2 a. In this way, each support assembly returns to the equilibrium state, and the support rod of the first support assembly 2a cannot be pressed down, so that the vibration amplitude of the pressure reducer 10 is greatly reduced.
It will be appreciated that the compressor 10 generates operating noise in addition to vibration noise, and that a muffler 6 may be mounted on the compressor to further reduce the noise of the compressor 10.
When the supporting device is applied to an outdoor unit of an air conditioner, the supporting device provided in this embodiment may be used to support a compressor 10 of the air conditioner, the compressor 10 has three feet (not shown), and each foot is connected to one supporting component 2, so that the stability of the compressor 10 can be ensured, and vibration can be avoided. In addition, in the carrying process of the air conditioner, the supporting device also plays a role in protecting the compressor 10, for example, when the compressor 10 inclines, the supporting device can perform the adjusting process on the compressor 10 as described above, so that the compressor 10 is kept stable under the action of the inclination force, the inclined bottom feet are restored to the original positions, and the compressor pipeline 7 (shown in fig. 4) is prevented from being damaged by pulling. It is understood that the compressor 10 may be provided with two feet or four feet, in which case, the supporting device is correspondingly provided with two supporting assemblies 2 or four supporting assemblies 2, and when the compressor 10 vibrates or tilts, the flow of the compressed medium is regulated between the first compression chamber 22 and the second compression chamber 23 of different cylinders 21, thereby achieving the purpose of stably supporting the compressor 10.
In this embodiment, both the compressible gas (e.g., air, inert gas) and the hydraulic oil can be used as the compression medium, and the first compression chamber 22 and the second compression chamber 23 are filled with the same compression medium.
In a further embodiment, 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 due to the tensile force or the pressure of the support object, and this expansion and contraction movement causes the pressure of the compressed medium in the first compression chamber 22 and the second compression chamber 23 to change, thereby allowing the compressed medium to flow in the first compression chamber 22 and the second compression chamber 23 which are communicated with each other, and allowing the entire support device to return to the equilibrium.
Based on the first embodiment described above, the present invention also proposes a second embodiment, as shown in fig. 9, in the second embodiment, the supporting device further includes: a first driving member (not marked in the figure), wherein the power output shaft of the first driving member is connected with the supporting part; pressure sensors (not shown) are provided on the compressor 10 and/or the support; the first controller is electrically connected with the first driving piece and the pressure sensor.
Different from the supporting device in the first embodiment, in which the supporting device provides the power for restoring the balance by the vibration of the supporting object, in this embodiment, the stress change of the supporting object is detected by the pressure sensor, the pressure sensor is electrically connected with the first controller, the real-time detected pressure value is transmitted to the first controller, the first controller stores the preset pressure parameter, when the pressure value exceeds the pressure parameter value, the first controller sends a control signal to the first driving member, and the first driving member pulls or presses down the supporting portion when receiving the control signal, so that the supporting rod 24 stretches and retracts along the cylinder 21. Unlike the first embodiment, which relies on the pressure of the medium to overcome the vibration tension or pressure, the driving force provided by the first driving member in this embodiment regulates the flow of the compressed medium, specifically, the damping control method is proposed as follows:
s1: acquiring pressure values detected by the pressure sensors;
s21: when the pressure value exceeds a preset range, acquiring a first driving piece corresponding to the pressure sensor with the pressure value exceeding the preset range, and controlling the first driving piece to drive the supporting rod to stretch so as to recover the pressure value detected by the pressure sensor to the preset range;
alternatively, the first and second electrodes may be,
s22: and when the pressure value exceeds the preset range, acquiring a second driving piece corresponding to the pressure sensor with the pressure value exceeding the preset range, and controlling the second driving piece to drive the piston of the energy accumulator to move so as to recover the pressure value detected by the pressure sensor to the preset range.
Taking the three support assemblies 2 mentioned in the first embodiment as an example, the three support assemblies 2 are named as a first support assembly 2a, a second support assembly 2b, and a third support assembly 2c, respectively, the support portion of each support assembly 2 is correspondingly connected with a first driving member, when it is detected that the pulling pressure applied to the first support assembly 2a is too large, the pressure sensor detects that the pressure value on the first support assembly 2a exceeds the preset range, the first controller controls the second support assembly 2b and/or the second driving member corresponding to the third support assembly 2c to drive the second support assembly 2b and the third support assembly 2c to rise, so that the second compression cavities 23 in the second cylinder and the third cylinder flow the compression medium to the first compression cavity 22 of the first cylinder, and thus the first compression cavity 22 in the first cylinder is rapidly filled with a large amount of compression medium, thereby suppressing the first support from descending. The pressure sensor detects the pressure of the supporting component 2 in real time, and once the first controller detects that the pressure of the first supporting component 2a returns to the preset range, the first controller controls the first driving part to stop applying the driving force to the second supporting component 2b and/or the third supporting component 2c, so that the pressure balance of the whole supporting component 2 is realized. In this embodiment, when the pressure sensor detects that the pressure value on the first supporting component 2a exceeds the preset range, the pressure sensor can further apply a driving force to the first supporting component 2a, so that the first driving component drives the first supporting component 2a to press down to overcome the situation that the supporting component is driven to rise by the supported object, thereby accelerating the speed of the supporting device for returning to balance. The predetermined range may be set as a range in which the compressor's own pressure is added or subtracted with a certain floating value, which may be a range of pressure variation allowed by vibration of the compressor, for example, a floating value having no influence on the operation performance, or a range of pressure variation not generating significant noise.

Of course, the first accumulator 32 and the second accumulator 33 may be connected to the connecting pipe between the first support assembly 2a and the second support assembly 2 b.
The second driving member is used for providing driving force for the first energy storage 32 and the second energy storage 33, is electrically connected with the second controller, and is started or closed according to a control signal of the second controller. The second controller controls the first accumulator 32 and the second accumulator 33 to open and close according to the pressure value detected by the pressure sensor, for example, when the support rod 24 is pressed down due to the pressure applied to the support assembly 2, the pressure sensor detects that the pressure value of the support assembly 2 exceeds a preset range, the second controller controls the second driving member to open the valve of the first accumulator 32 to receive the compressed medium, and simultaneously controls the second driving member to drive the piston of the second accumulator 33 to inject the compressed medium into the support assembly 2, so that the support device is balanced. When the supporting rod 24 is pressed, and the pressure sensor detects that the pressure value of the supporting component 2 exceeds the preset range, the second controller controls the second driving component to drive the valve of the second energy storage 33 to open so as to receive the compressed medium, and drive the piston 25 of the second energy storage 33 to move, so that the compressed medium in the first energy storage 32 flows out. The second driving piece is controlled by the second controller to provide power for balance of the whole supporting device, so that the speed of returning balance of the supporting device is increased, all feet of the compressor 10 can be always located in the same horizontal plane, and a good stabilizing effect is achieved. In this embodiment, the second controller is used to control the opening and closing of the first energy storage device 32 and the second energy storage device 33 so as to adjust the whole supporting device, so that the compressed medium can quickly reach a balanced state, the movement amplitude of the supporting rod is extremely small, the movement stability can be maintained, and the vibration phenomenon is avoided.

Of course, the first compression chamber 22 in the same cylinder 21 communicates with the second compression chamber 23 connected to the second accumulator 33 in addition to the first accumulator 32, and the second compression chamber 23 in the same cylinder 21 communicates with the first compression chamber 22 connected to the first accumulator 32 in addition to the second accumulator 33. In this embodiment, the first energy storage 32 and the second energy storage 33 work in a linkage manner, for example, the first energy storage 32 is connected to the first compression chamber 22 and the second energy storage 33 is connected to the second compression chamber 23 in the same support assembly 2, when the support rod 24 is pressed down, the pressure in the first compression chamber 22 increases, the compression medium flows into the first energy storage 32, the pressure in the second compression chamber 23 decreases, and the compression medium flows into the second compression chamber 23 from the second energy storage 33.

s112: or when the pressure value exceeds the preset range, acquiring a second driving piece corresponding to the pressure sensor with the pressure value smaller than the minimum pressure value of the preset range, and controlling the acquired second driving piece to drive the supporting rod to move upwards.
The pressure value exceeding the preset range includes being smaller than the preset range and being larger than the preset range, taking the three support assemblies 2 mentioned in the first embodiment as an example:
when the first support assembly 2a is pressed downwards, the pressure sensor detects that the pressure value on the first support assembly 2a is larger than the preset range, the first controller controls the first driving part to drive the support part to move downwards, the compressed medium in the first compression cavity 22 of the first support assembly 2a flows into the second compression cavity 23 in the second support assembly 2b and the second compression cavity 23 in the third support assembly 2c, and the compressed medium in the first compression cavity 22 in the second support assembly 2b and the first compression cavity 23 in the third support assembly 2c flows into the second compression cavity 23 of the first support assembly 2 a. In this way, each support assembly returns to the equilibrium state, and the support rod of the first support assembly 2a cannot be pressed down, so that the vibration amplitude of the pressure reducer 10 is greatly reduced.
When the first support component 2a is under tension, the first support component is stretched, the first controller controls the first driving component to drive the support component to move upwards, so that the compressed medium in the second compression cavity 23 in the first support component 2a flows into the two first compression cavities 22 communicated with the second compression cavity 23 (the first compression cavity 22 corresponding to the second support component 2b and the first compression cavity 22 corresponding to the third support component 2 c), the adjusting end of the second support component 2b and the adjusting end of the third support component 2c both move towards the second compression cavity 23 under the pushing of the pressure, so that the volume of the second compression cavity 23 is reduced, the volume of the first compression cavity 22 is increased, the positions of the second support component 2b and the third support component 2c fixed on the support object are raised, the second compression cavity 23 in the second support component 2b and the second compression cavity 23 in the third support component 2c are reduced due to the reduction of the volumes, the compressed medium further flows into the first compression chamber 22 in the first support member 2a, so that the compressed medium in the first compression chamber 22 in the first cylinder is replenished. In this way, the compression medium of the entire adjustment device is not changed, each support member 2 is restored to the equilibrium state, the vibration or inclination of the support object is adjusted, the stability is ensured, and the generation of vibration noise of the compressor 10 is also suppressed.
In this embodiment, owing to receive the drive power of first driving piece, can accelerate strutting arrangement and return balanced speed, realize quick adjustment compressor and reach stable state, make compressor 10's footing vibration amplitude reduce, adjust effectually.
It is understood that in another embodiment, the photoelectric sensor may be utilized to detect the position of the feet of the compressor 10 and transmit the detected position to the first controller, and the first controller controls the first driving member to provide driving force to the supporting component 2 according to the height of the feet of the compressor 10, for example, when detecting that the feet of the compressor 10 connected to the first supporting component 2a are raised, the first driving members corresponding to the second supporting component 2b and the third supporting component 2c are controlled to drive the second supporting component 2b and the third supporting component 2c to rise, or the first driving members corresponding to the first supporting component 2a are controlled to drive the first supporting component 2a to press down, so that the whole supporting device rapidly returns to balance.

s211: when the pressure value is larger than a preset range, controlling the energy accumulator to be opened to receive a compressed medium;
s212: acquiring a second driving piece corresponding to the pressure sensor with the pressure value smaller than the minimum pressure value in the preset range;
s213: and controlling a second driving assembly connected with the energy accumulator to drive a piston of the energy accumulator so as to recover the pressure value detected by the pressure sensor to be within the preset range.
The second controller controls the first accumulator 32 and the second accumulator 33 to open and close according to the pressure value detected by the pressure sensor, for example, when the support rod 24 is pressed down due to the pressure applied to the support assembly 2, the pressure sensor detects that the pressure value of the support assembly 2 is greater than a preset range, the second controller controls the second driving member to open the valve of the first accumulator 32 to receive the compressed medium from the first compression cavity 22, and simultaneously controls the second driving member to drive the piston of the second accumulator 33 to inject the compressed medium into the second compression cavity 23 of the support assembly 2, so as to balance the support device. When the supporting rod 24 is pressed, and the pressure sensor detects that the pressure value of the supporting component 2 is smaller than the preset range, the second controller controls the second driving member to drive the valve of the second energy storage 33 to open so as to receive the compressed medium from the second compression cavity 23, and drive the piston 25 of the second energy storage 33 to move, so that the first energy storage 32 injects the compressed medium into the first compression cavity 23. The second driving piece is controlled by the second controller to provide power for balance of the whole supporting device, so that the speed of returning balance of the supporting device is increased, all feet of the compressor 10 can be always located in the same horizontal plane, and a good stabilizing effect is achieved.
