Description

Technical Field

[0001] This invention relates to the field of air conditioning design technology, and more specifically, to an air conditioning positioning device, control method, and air conditioner. Background Technology

[0002] Compressor foot pads provide vibration damping for the compressor. Made of a low-stiffness material, they mitigate compressor vibration energy and are equipped with compressor positioning bolts to secure the pads and prevent significant compressor displacement under external impact, which could lead to pipe breakage or collision deformation with other structural components. This is especially important for parking air conditioners, which, in addition to potential impacts such as bumps and drops during transport, may also be subjected to prolonged exposure to various complex road conditions during operation. In existing technologies, such as... Figure 1 and Figure 2 As shown, in order to reduce large deformation of the foot pads, stepped positioning bolts are usually used. The nuts are tightened onto the stepped surface of the positioning bolts at the factory, so that the foot pads have a large amount of compression and will not deform significantly. However, this solution greatly reduces the vibration damping performance of the compressor foot pads, so that the vibration energy of the compressor cannot be effectively attenuated, resulting in poor vibration and noise of the whole machine.

[0003] There is currently no effective solution to the aforementioned problems in the existing technology. Summary of the Invention

[0004] The main objective of this invention is to provide an air conditioner positioning device, control method, and air conditioner to solve the problem of poor vibration and noise performance of air conditioners in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, an air conditioner positioning device is provided, comprising: a first connector having a first thread on its outer peripheral surface and a first platform on its outer side; a second connector located at the bottom of the first connector and connected to a mounting base, the second connector having a mounting cavity at its top end, a second thread engaging with the first thread on the side wall of the mounting cavity, and a second platform on its outer side, forming a compression space for accommodating a compression foot pad between the first platform and the second platform; wherein adjusting the engagement depth of the first thread of the first connector and the second thread of the second connector allows the height of the compression space to be variablely set.

[0006] Furthermore, the air conditioning positioning device includes: a driving part, which is connected to the top end of the first connecting member. The driving part is used to drive the first connecting member to rotate around its own central axis to adjust the engagement depth of the first thread and the second thread.

[0007] Furthermore, the drive unit is connected to the first connector via a magnetic attraction structure or a snap-fit ​​structure.

[0008] Furthermore, the first connector has a compressed position where the first thread and the second thread are fully engaged, and a relaxed position where the first thread and the second thread are at least partially disengaged. When the first connector is in the compressed position, the height of the compressed space is at its minimum.

[0009] Furthermore, the bottom surface of the first platform abuts against the top surface of the compression foot pad, and the top surface of the second platform abuts against the bottom surface of the compression foot pad.

[0010] Furthermore, the compression foot pad includes an upper foot pad and a lower foot pad spaced apart along the height direction, with the upper foot pad and the lower foot pad forming an installation space for installing the air conditioner base.

[0011] According to one aspect of the present invention, a control method for an air conditioner positioning device is provided. The control method is used to control the air conditioner positioning device described above. The method includes: detecting whether the air conditioner is in an on-state; if so, controlling a first connecting member to move to a relaxed position; if not, controlling the first connecting member to move to a compressed position.

[0012] Furthermore, after controlling the first connector to move to the compression position, the method further includes: acquiring acceleration information detected by an acceleration sensor within a preset time period, the acceleration sensor being disposed on at least one of the first connector and the second connector; determining, based on the acceleration information, whether the rate of change of acceleration within the preset time period is greater than a preset value; if so, controlling the drive unit to rotate forward to increase the engagement depth of the first thread and the second thread; if not, controlling the first connector to move to the release position.

[0013] Furthermore, before detecting whether the air conditioner is in operation, the method also includes: detecting whether the air conditioner is in transport mode; if so, controlling the first connecting member to move to the compression position.

[0014] According to another aspect of the present invention, an air conditioner is provided, including an air conditioner positioning device, wherein the air conditioner positioning device is the air conditioner positioning device described above.

[0015] By applying the technical solution of this invention, the height of the compression space can be varied by adjusting the engagement depth of the first thread of the first connector and the second thread of the second connector. This allows for controllable compression of the compression foot pads, enabling increased compression during transportation or certain operating conditions to prevent significant deformation of the compression foot pads. Conversely, it allows for reduced compression during air conditioning operation to improve vibration damping of the compressor, thereby enhancing the vibration and noise performance of the air conditioner. The technical solution of this application effectively solves the problem of poor vibration and noise performance in existing air conditioners. Attached Figure Description

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

[0037] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0038] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0039] Combination Figures 3 to 11 As shown, according to a specific embodiment of this application, an air conditioning positioning device is provided.

[0040] The air conditioner positioning device includes: a first connector 10, with a first thread on its outer circumferential surface and a first platform 11 on its outer side; a second connector 20, located at the bottom of the first connector 10 and connected to a mounting base, with a mounting cavity at its top, a second thread on the side wall of the mounting cavity engaging with the first thread, and a second platform 21 on its outer side, forming a compression space between the first platform 11 and the second platform 21 to accommodate a compression foot pad 30; wherein, by adjusting the engagement depth of the first thread of the first connector 10 and the second thread of the second connector 20, the height of the compression space can be set variablely.

[0041] By applying the technical solution of this application, the height of the compression space can be varied by adjusting the engagement depth of the first thread of the first connector 10 and the second thread of the second connector 20. This allows for controllable compression of the compression foot pad 30, enabling the compression to be increased during transportation or certain operating conditions to prevent significant deformation of the compression foot pad 30. Conversely, the compression can be reduced during air conditioning operation to improve its vibration damping effect on the compressor, thereby improving the vibration and noise performance of the air conditioner. The technical solution of this application effectively solves the problem of poor vibration and noise performance in existing air conditioners.

[0042] like Figure 5 A longitudinal sectional view of an air conditioner positioning device is shown. The device includes a drive unit 40 connected to the top end of a first connecting member 10. The drive unit 40 drives the first connecting member 10 to rotate around its own central axis to adjust the engagement depth of the first thread and the second thread. This configuration automates the change of foot pad compression, making the change in compression more precise. The output of the drive unit 40 has a linear relationship with the engagement depth, and the engagement depth also has a linear relationship with the foot pad compression, thus improving the control accuracy of the device. Figure 5 Compressor 60 is also shown.

[0043] Furthermore, the drive unit 40 is connected to the first connector 10 via either a magnetic suction structure 41 or a snap-fit ​​structure. This embodiment's technical solution ensures both good connection stability between the drive unit 40 and the first connector 10, while also facilitating assembly and disassembly. Since the parking air conditioner has a transport mode, the above-mentioned arrangement allows the drive unit 40 to be disassembled first, thereby ensuring its positioning and control accuracy.

[0044] Furthermore, the first connector 10 has a compressed position where the first thread and the second thread are fully engaged, and a relaxed position where the first thread and the second thread are at least partially disengaged. When the first connector 10 is in the compressed position, the height of the compressed space is at its minimum. Figure 6 A relaxed position is shown. Figure 7 The compression position is shown. The engagement depth of the first and second threads determines the height of the compression space, which in turn controls the deformation of the compression foot pad. Figure 8 and Figure 9 These are schematic diagrams showing the fit between the first and second connectors after removing the compression foot pads.

[0045] Specifically, the first connecting component is the first bolt (upper bolt), and the second connecting component is the second bolt (lower bolt). The upper and lower bolts of the positioning bolt can be adjusted by rotating the motor to change the formation of the threads, thereby changing the compression of the positioning bolt on the compressor foot pad and thus changing the rigidity of the foot pad.

[0046] Optionally, the bottom surface of the first platform 11 abuts against the top surface of the compression foot pad 30, and the top surface of the second platform 21 abuts against the bottom surface of the compression foot pad 30. This arrangement allows for more precise control of the deformation of the compression foot pad 30 and prevents gaps between the compression foot pad 30 and the two platforms from reducing control precision.

[0047] Furthermore, the compression foot pad 30 includes an upper foot pad 31 and a lower foot pad 32 spaced apart along the height direction, forming an installation space between the upper foot pad 31 and the lower foot pad 32 for mounting the air conditioner base 50. This split arrangement of upper and lower parts more effectively absorbs the vibration energy of the air conditioner base 50, preventing displacement and noise generation.

[0048] The drive unit 40 is connected to the first connecting member 10 via a magnetic attraction structure 41. Besides the magnetic connection in this design, other connection methods such as snap-fit ​​can also be designed to ensure the connection between the drive unit 40 and the first connecting member 10. The first connecting member 10 is threadedly connected to the lower bolt, and the height of the first connecting member 10 can be adjusted by the stroke of the thread. The first connecting member 10 has a large contact surface that can contact the foot pad. The second connecting member 20 is spot-welded or riveted to the chassis. After the drive unit 40 is powered on, the rotation of the drive unit 40 can be adjusted to drive the first connecting member 10 to rotate, thus adjusting the thread stroke. When the stroke is downward, the contact surface between the first connecting member 10 and the foot pad compresses the foot pad downward, giving the foot pad greater rigidity. When the stroke is upward, the contact surface between the first connecting member 10 and the foot pad moves away from the foot pad, allowing the foot pad to move more freely and have a better deformation energy absorption effect.

[0049] The installation steps of the air conditioner positioning device are as follows: During production, the second connecting piece 20 is first connected to the chassis, and then the foot pad is compressed to a compressed state through the first connecting piece 10. Then, the drive unit 40 is connected to the first connecting piece 10 through the magnetic structure 41, so that the positioning bolt is in a compressed state. The compressor foot pad is significantly compressed and has greater rigidity. During the transportation of the product, it can effectively prevent the compressor and pipeline from undergoing large deformation, which could lead to collision or damage.

[0050] According to a specific embodiment of this application, a control method for an air conditioner positioning device is provided. The method controls the air conditioner positioning device in the above embodiment. The method includes: detecting whether the air conditioner is in an on / off state; if so, controlling the first connecting member 10 to move to a relaxed position; if not, controlling the first connecting member 10 to move to a compressed position. Figure 11 A flowchart illustrating the control method of the air conditioning positioning device is shown. In this flowchart, state 2 is the compression state, in which the first connecting member 10 is in the compression position, and state 1 is the relaxation state, in which the first connecting member 10 is in the relaxation position.

[0051] like Figure 11 As shown, after controlling the first connector 10 to move to the compression position, the method further includes: acquiring acceleration information detected by an acceleration sensor within a preset time period, wherein the acceleration sensor is disposed on at least one of the first connector 10 and the second connector 20; determining whether the rate of change of acceleration within the preset time period is greater than a preset value based on the acceleration information; if so, controlling the drive unit 40 to rotate forward to increase the engagement depth of the first thread and the second thread; if not, controlling the first connector 10 to move to the release position.

[0052] Specifically, when the prototype is powered on, the motor rotates, placing the positioning bolt (also known as the first and second connecting parts) in state 1. At this time, the compressor feet are not compressed, allowing for better dissipation of vibration energy and reducing overall vibration and noise. An accelerometer on the positioning bolt monitors its vibration. When the overall structure is relatively stable, the positioning bolt remains in state 1. When the accelerometer detects a sudden large vibration change, the motor rotates, increasing the thread pitch according to the vibration magnitude to compress the compressor feet, preventing significant deformation that could damage pipes or cause structural impacts. Once the accelerometer detects that the foot vibration has stabilized, the motor rotates, returning the positioning bolt to state 1. When the prototype is powered off, the motor automatically returns the positioning bolt to state 2, ensuring structural reliability and maintaining comfortable noise and vibration levels even on complex road conditions.

[0053] Before checking whether the air conditioner is in operation, the method also includes: checking whether the air conditioner is in transport mode; if so, controlling the first connecting part 10 to move to the compression position. Specifically, the parking air conditioner control function is divided into parking mode and operating mode. When a large impact occurs, the vibration sensor on the bolt will change the compression amount of the foot pad to ensure the comfort of the air conditioner's operating noise and vibration, while ensuring the reliability of the parking air conditioner pipeline and structural components.

[0054] According to another aspect of the present invention, an air conditioner is provided, including an air conditioner positioning device, wherein the air conditioner positioning device is the air conditioner positioning device described above.

[0055] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: on the one hand, it solves the problem that the compressor and pipeline of the parking air conditioner may be greatly deformed during transportation, resulting in collision or damage; on the other hand, it solves the problem that the parking air conditioner may have poor noise and vibration due to increased rigidity caused by compression of the foot pads during operation.

[0056] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0057] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application.

Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this invention.

[0058] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
