Description

Technical Field

[0001] This application relates to the field of motor mounting technology, and in particular to a motor mounting device, an air conditioner, and a control method thereof. Background Technology

[0002] As the core power component of various mechanical equipment, the reliability of the motor's mounting directly affects the safe operation and service life of the equipment. In equipment such as air conditioners, fans, and pumps, the motor is usually fixed to the bracket via mounting feet. The quality of the mounting directly affects the vibration level, noise level, and operational stability of the equipment.

[0003] Currently, motor mounting primarily uses bolt connections, where multiple mounting feet of the motor are fixed to a bracket using bolts. While this traditional method provides sufficient strength during initial installation, it presents a key technical problem during long-term operation: the inability to monitor changes in the motor's mounting status in real time leads to the failure to promptly detect and address any mounting abnormalities.

[0004] Specifically, traditional motor mounting methods have the following technical drawbacks:

[0005] The lag issue in fixed-state monitoring: During operation, motors generate dynamic loads such as vibration and centrifugal force, which, over time, can lead to fixing abnormalities such as loose bolts and worn mounting feet. However, traditional fixing methods cannot detect these changes and can only discover problems through periodic manual inspections or waiting for obvious signs of malfunction. This passive monitoring method has a significant lag, easily allowing small problems to gradually escalate into major failures.

[0006] Uncontrollable aspects of fastening quality: The tightening torque of bolts depends on the operator's experience and skill, making it difficult to guarantee consistency. Even if the initial installation meets requirements, the degree of bolt loosening during operation cannot be quantitatively assessed, and there is a lack of objective criteria for judging fastening quality.

[0007] Blindness in maintenance management: Due to the lack of real-time status information, equipment maintenance often adopts a periodic maintenance mode, which requires inspection regardless of whether the fixed status is normal or not. This increases maintenance costs and may cause the opportunity to miss the time when maintenance is really needed.

[0008] Unpredictability of safety hazards: When a motor's fixing abnormality gradually worsens but has not yet completely failed, the equipment may still be operating but poses a safety hazard. Due to the lack of early warning mechanisms, this potential risk is often only discovered after equipment damage or a safety accident has occurred.

[0009] This problem is particularly prominent in air conditioner applications. Air conditioners need to operate continuously for extended periods, and improper motor mounting can lead to increased vibration and noise, affecting the user experience; in severe cases, it can cause motor damage or detachment, posing a safety hazard. Traditional periodic maintenance methods not only increase maintenance costs but also fail to meet the reliability and safety requirements of modern smart home appliances. Summary of the Invention

[0010] This application provides a motor fixing device, an air conditioner, and a control method thereof. The motor fixing device can monitor the motor fixing status in real time, detect fixing abnormalities in a timely manner, and ensure the reliability of motor operation.

[0011] In a first aspect, this application provides a motor fixing device, comprising: a bracket; multiple fixing mechanisms disposed on the bracket for fixing multiple mounting feet of the motor respectively; multiple pressure sensors for monitoring pressure information at the multiple mounting feet respectively; and a controller connected to the multiple pressure sensors for determining the fixing state of the motor based on the pressure information.

[0012] In one possible implementation, the fixing mechanism includes: a locking body fixed to the bracket, the locking body including a first locking and an unlocking mechanism; a connector connected to the motor, the connector including a second locking, the second locking including a first state locked with the first locking and a second state separated from the first locking; wherein, the unlocking mechanism is used to release the first state of the second locking, and a pressure sensor is disposed on the first locking or the second locking.

[0013] In one possible implementation, the latch body is provided with a slot, and the first latch is disposed in the slot; the connector is provided with a plug-in part for insertion into the slot, and the second latch is disposed in the plug-in part.

[0014] In one possible implementation, the fixing mechanism further includes an anti-loosening component, which is disposed on the locking body and is used to restrict the second locking from switching from the first state to the second state.

[0015] In one possible implementation, the fixing mechanism includes: a base connected to a bracket; a snap-fit ​​body movably disposed on the base, the snap-fit ​​body having a snap-fit ​​element for snapping the mounting foot; wherein a pressure sensor is disposed at the snap-fit ​​element or the mounting foot.

[0016] In one possible implementation, the clamping element includes an elastic telescopic portion, and a pressure sensor is disposed on the elastic telescopic portion.

[0017] In one possible implementation, the pressure sensor is positioned in the force transmission path between the motor and the support.

[0018] Secondly, embodiments of this application provide an air conditioner, including: a motor; and the aforementioned motor fixing device.

[0019] Thirdly, this application provides a control method for the above-mentioned air conditioner, including the following steps: obtaining pressure information of each mounting foot of the motor; analyzing the motor fixing status based on the pressure information; and when a fixing abnormality is detected, determining the fault level and executing a corresponding protection strategy based on the number and distribution characteristics of the abnormal fixing points.

[0020] In one possible implementation, the fault level determination includes: when there is one abnormal fixed point, it is judged as a minor fault, the motor speed is reduced and a warning signal is issued; when there are two abnormal fixed points, the spatial distribution relationship of the abnormal points is analyzed: if they are adjacent, it is judged as a minor fault, the motor speed is reduced and a warning signal is issued; if they are diagonally distributed, it is judged as a severe fault, the machine is stopped and an alarm signal is issued; when there are more than two abnormal fixed points, it is judged as a severe fault, the machine is stopped and an alarm signal is issued.

[0021] One possible implementation also includes: monitoring the dynamic changes in pressure information at each mounting foot of the motor; determining abnormal vibration when the fluctuation amplitude of the pressure information exceeds a preset threshold; and adjusting the motor operating parameters to optimize vibration characteristics.

[0022] In one possible implementation, monitoring the dynamic changes in pressure information includes: collecting pressure information within a preset time range and calculating the fluctuation range of the pressure information.

[0023] In one possible implementation, adjusting the motor operating parameters includes: after detecting abnormal vibration, adjusting the motor speed while meeting the air volume requirements, and recording the number of faults; reassessing the vibration state of the motor, and if the abnormal vibration persists, repeating the above speed adjustment; if the abnormal vibration is eliminated, the fault count is reset to zero, and the motor runs at this speed; when the number of faults reaches a preset upper limit, a protective shutdown is performed.

[0024] Compared with existing technologies, the technical solution provided in this application has the following advantages: By integrating a bracket, multiple fixing mechanisms, multiple pressure sensors, and a controller, it systematically solves the core technical problem of traditional motor fixing methods that "cannot monitor changes in the motor's fixing state in real time, leading to the inability to detect and handle fixing abnormalities in a timely manner." Its technical implementation principle is based on the innovative concept of "digital perception of physical state": multiple fixing mechanisms correspond to multiple mounting feet of the motor, serving as carriers for state perception while achieving physical fixing; multiple pressure sensors monitor the pressure information at each mounting foot, converting the traditionally imperceptible fixing state into a digitally detectable signal in real time; the controller receives and analyzes multi-point pressure data, and uses algorithms to determine the overall fixing state of the motor, achieving quantitative and intelligent assessment of the fixing state. This integrated "fixing + sensing + analysis" technical architecture fundamentally changes the technical mode of motor fixing state management, thereby enabling real-time monitoring of the motor's fixing state, timely detection of fixing abnormalities, and ensuring the reliability of motor operation.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0046] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0047] like Figures 1-10 As shown, this application embodiment provides a motor fixing device, including: a bracket 1, multiple fixing mechanisms 2, multiple pressure sensors 3, and a controller (not shown), wherein:

[0048] Multiple fixing mechanisms 2 are mounted on the bracket 1 and are used to fix multiple mounting feet 41 of the motor 4.

[0049] Multiple pressure sensors 3 are used to monitor the pressure information at multiple mounting feet 41.

[0050] The controller is connected to multiple pressure sensors 3 to determine the stationary state of the motor 4 based on pressure information.

[0051] In this invention, intelligent real-time monitoring of the fixed state of the motor 4 is achieved through a combination of a bracket 1, multiple fixing mechanisms 2, multiple pressure sensors 3, and a controller. The technical principle is as follows: multiple fixing mechanisms 2 respectively fix multiple mounting feet 41 of the motor 4, ensuring stable installation of the motor 4; multiple pressure sensors 3 respectively monitor the pressure information at each mounting foot 41, converting physical pressure into electrical signals; the controller receives and analyzes this pressure information, and determines the fixed state of the motor 4 through an algorithm, thereby achieving intelligent assessment of the reliability of the motor 4's fixation.

[0052] Specifically, bracket 1 serves as the basic support structure for the entire fixing device, providing an installation base for multiple fixing mechanisms 2. Multiple fixing mechanisms 2 are mounted on bracket 1, each corresponding to a mounting foot 41 of motor 4, achieving reliable fixing of motor 4 to bracket 1 through mechanical connection. Multiple pressure sensors 3 are used to monitor pressure information at multiple mounting feet 41, with each sensor corresponding to one mounting foot 41, achieving comprehensive pressure monitoring. The controller is electrically connected to the multiple pressure sensors 3, receiving pressure signals from each sensor in real time. Through a built-in algorithm, it analyzes the changing patterns and anomalies of the pressure data to determine whether the fixing status of motor 4 is normal.

[0053] In one specific embodiment, when the motor fixing device is used to fix the fan motor 4 of an air conditioner, four fixing mechanisms 2 respectively fix the four mounting feet 41 of the fan motor 4, and four pressure sensors 3 respectively monitor the force on each mounting foot 41. Under normal operating conditions, the pressure values ​​displayed by each pressure sensor 3 should be within a preset range and relatively balanced. When a mounting foot 41 becomes loose, the corresponding pressure sensor 3 will detect an abnormal drop in pressure. The controller immediately recognizes this abnormality and determines that the fixing is faulty, and can take timely protective measures to avoid damage to the motor 4 or safety accidents caused by poor fixing.

[0054] In related technologies, the traditional method of fixing motor 4 mainly uses bolts, which makes it impossible to monitor changes in the fixing status in real time. Operators can only discover fixing problems through periodic inspections or after a fault occurs. This passive monitoring method has obvious lag and cannot detect and deal with fixing abnormalities in a timely manner. It is easy for motor 4 to operate in a poorly fixed state for a long time, increasing the risk of equipment damage and safety accidents.

[0055] In this embodiment of the invention, multiple pressure sensors 3 monitor the pressure changes of each mounting foot 41 in real time, and the controller continuously analyzes the pressure data, achieving a technological leap from passive detection to active monitoring. Compared with traditional methods, this solution can perceive subtle changes in the fixing state of the motor 4 in real time, promptly detect fixing abnormalities, and provide real-time assurance for the safe and reliable operation of the motor 4. This active monitoring method greatly improves the reliability and safety of the motor 4 fixing, effectively avoiding equipment damage and safety hazards caused by fixing problems.

[0056] like Figure 2-4 As shown, in some embodiments, the fixing mechanism 2 includes: a locking body 21, fixed to the bracket 1, the locking body 21 including a first locking buckle 211 and an unlocking mechanism 212; a connector 22, connected to the motor 4, the connector 22 including a second locking buckle 221, the second locking buckle 221 including a first state of being locked with the first locking buckle 211 and a second state of being separated from the first locking buckle 211; wherein, the unlocking mechanism 212 is used to release the first state of the second locking buckle 221, and the pressure sensor 3 is disposed on the first locking buckle 211 or the second locking buckle 221.

[0057] In this invention, the snap-fit ​​structure design of the locking body 21 and the plug-in component 22, combined with the integrated configuration of the pressure sensor 3, achieves the integration of rapid fixation and status monitoring of the motor 4. The technical principle is as follows: the locking body 21 is fixed to the bracket 1 and includes a first locking buckle 211 and an unlocking mechanism 212; the plug-in component 22 is connected to the motor 4 and includes a second locking buckle 221, which can switch between locked and unlocked states; when the second locking buckle 221 is in the first state, it locks with the first locking buckle 211 to fix the motor 4; the unlocking mechanism 212 is used to release the locked state, enabling rapid assembly and disassembly; the pressure sensor 3 is installed on either the first locking buckle 211 or the second locking buckle 221, synchronously monitoring the locking force during the fixing process.

[0058] Specifically, the latch body 21, as a fixed end structure, is fixed to the bracket 1 by welding or bolting. Its internal first latch 211 serves as the fixed part of the locking mechanism. The unlocking mechanism 212 is designed as a press-sensitive elastic element, which can be triggered by the operator pressing it. The connector 22, as a movable end structure, is rigidly connected to the mounting foot 41 of the motor 4. Its second latch 221 is designed as an elastic structure, capable of automatically deforming during insertion and automatically locking after reaching the correct position. The first state refers to the fully engaged locking state of the second latch 221 and the first latch 211, at which point the motor 4 is firmly fixed. The second state refers to the separated state, at which point the motor 4 can be freely disassembled. The pressure sensor 3 detects the contact pressure between the latches to reflect the tightness of the fixation in real time.

[0059] In one specific embodiment, when maintenance personnel need to replace the air conditioner fan motor 4, they only need to press the unlocking mechanism 212, and the second latch 221 will switch from the first state to the second state, allowing the motor 4 to quickly separate. When installing a new motor 4, the connector 22 is inserted into the latch body 21, and the second latch 221 automatically locks to the first state. The entire process requires no tools, greatly improving assembly and maintenance efficiency compared to traditional bolt fixing methods. Simultaneously, the pressure sensor 3 monitors the locking pressure in real time to ensure proper fixing. When the locking force is insufficient, the controller will issue a warning, guaranteeing the quality of the fixing.

[0060] In related technologies, traditional bolt fixing methods require the use of specialized tools such as wrenches, and the assembly and disassembly processes are cumbersome and time-consuming. Moreover, the fixing quality depends on the experience and skills of the operators, making it difficult to guarantee consistency. More importantly, changes in the tightness of bolts cannot be monitored after fixing, and loosening of bolts cannot be detected in time.

[0061] In this embodiment of the invention, the snap-on structure enables tool-free, rapid fixing and disassembly, greatly improving operational efficiency and convenience. The integrated design of the pressure sensor 3 achieves the integration of fixing and monitoring functions, providing a convenient fixing method while also monitoring the fixing status in real time, ensuring the controllability and traceability of fixing quality. This integrated design offers significant improvements in efficiency, convenience, and reliability compared to traditional methods.

[0062] In some embodiments, the latch body 21 is provided with a slot 213, and the first latch 211 is disposed in the slot 213; the connector 22 is provided with a plug portion 222, which is used to be inserted into the slot 213, and the second latch 221 is disposed in the plug portion 222.

[0063] In this invention, the precise fit between the slot 213 of the locking body 21 and the insertion part 222 of the connector 22 achieves accurate positioning and stable connection of the snap-fit ​​fastening. The technical principle is as follows: the locking body 21 is provided with a dedicated slot 213, providing an accurate insertion path and positioning reference for the connector 22; the connector 22 is provided with an insertion part 222 that matches the slot 213, ensuring guidance during insertion and stability after insertion; the first latch 211 is located within the slot 213, and the second latch 221 is located within the insertion part 222. During insertion, the two naturally align and lock, avoiding poor locking due to positioning deviations.

[0064] Specifically, the slot 213 serves as an open receiving structure for the locking body 21, and its inner wall shape precisely matches the shape of the insertion part 222, playing a guiding and limiting role. The first latch 211 is located at a specific position within the slot 213, serving as the fixed end of the locking mechanism. The insertion part 222, as the main structure of the insertion member 22, has its outer dimensions precisely matched with the inner cavity of the slot 213, ensuring a smooth insertion process and no wobbling after insertion. The second latch 221 is located at a predetermined position in the insertion part 222, precisely corresponding to the position of the first latch 211, ensuring that the two latches can accurately engage when inserted.

[0065] In one specific embodiment, when installing the air conditioner fan motor 4, the operator aligns the plug portion 222 of the connector 22 with the slot 213 of the locking body 21. Due to the precise fit design, the plug portion 222 can be smoothly inserted into the slot 213 without jamming or misalignment. During insertion, the inner wall of the slot 213 guides the plug portion 222, ensuring correct insertion direction. When the plug portion 222 is fully inserted, the second locking buckle 221 on the plug portion 222 accurately aligns with the first locking buckle 211 in the slot 213 and automatically locks, achieving reliable fixation. This precise fit design greatly reduces the difficulty of operation and improves the assembly success rate.

[0066] The above technical solution still suffers from insufficient positioning accuracy during insertion. Although it achieves quick fixation via a snap-fit ​​mechanism, if there is a lack of a precise positioning mechanism between the plug-in component 22 and the locking body 21, problems such as misalignment, jamming, or incomplete locking may occur during insertion, affecting the fixation quality and ease of operation.

[0067] In this embodiment of the invention, the precise fit design of the slot 213 and the insertion part 222 provides an accurate positioning reference and guiding mechanism for the snap-fit ​​fixing. The slot 213 not only serves to accommodate but, more importantly, provides precise positional constraints, ensuring that the insertion part 222 can only be inserted along the designed path. The shape design of the insertion part 222 perfectly matches the slot 213, eliminating positional uncertainty during insertion. Compared with a simple snap-fit ​​structure, this precise fit design significantly improves positioning accuracy, operational convenience, and fixing reliability, ensuring that each assembly achieves the required fixing quality.

[0068] In some embodiments, the fixing mechanism 2 further includes an anti-loosening component 23, which is disposed on the locking body 21 and is used to restrict the second locking buckle 221 from switching from the first state to the second state.

[0069] In this invention, by adding an anti-loosening component 23 to the fixing mechanism 2, the snap-lock fastening mechanism is protected against accidental loosening. The technical principle is as follows: the anti-loosening component 23 is installed on the locking body 21, and through physical restriction, prevents the second locking buckle 221 from switching from the first state (locked state) to the second state (disengaged state). Even under external force or accidental contact with the unlocking mechanism 212, the motor 4 remains fixed, avoiding safety hazards caused by accidental loosening.

[0070] Specifically, the anti-loosening component 23, as an independent safety device, is fixed to the latch body 21 via a detachable connection. Its structural design effectively restricts the state switching action of the second latch 221. Once the anti-loosening component 23 is installed, even if the unlocking mechanism 212 is accidentally triggered, the second latch 221 cannot switch from the first state to the second state, thus maintaining the fixed state of the motor 4. Disassembling the anti-loosening component 23 requires specific operating procedures and usually necessitates manual operation. This ensures safety without affecting normal maintenance and disassembly needs.

[0071] There are two second latches 221, and there is a space between the two second latches 221. The two second latches 221 switch from the first state to the second state by bending and deforming towards the space. The anti-loosening part 23 has a limiting part, which is inserted into the space to restrict the bending and deformation of the two second latches 221 towards the space, thereby preventing the second latches from switching from the first state to the second state.

[0072] In one specific embodiment, the air conditioner vibrates during operation, which may impact the snap-fit ​​fixing mechanism 2, posing a risk of triggering the unlocking mechanism 212 and causing the motor 4 to accidentally loosen. With the anti-loosening component 23 installed, even if the unlocking mechanism 212 is accidentally triggered under strong vibration, the second latch 221 remains locked in the first state, and the motor 4 remains firmly fixed. Only when maintenance is required can the maintenance personnel remove the anti-loosening component 23 before they can normally operate the unlocking mechanism 212 to disassemble the motor 4. This design ensures safe daily operation without affecting normal maintenance procedures.

[0073] The above technical solution still has the drawback of insufficient ability to prevent accidental loosening. Although the snap-fit ​​structure achieves quick fixation and precise positioning, the unlocking mechanism 212 may be accidentally triggered under vibration or accidental external force, causing the second latch 221 to switch from the first state to the second state unexpectedly, resulting in the motor 4 becoming loose and posing a safety hazard.

[0074] In this embodiment of the invention, the addition of the anti-loosening component 23 as a snap-fit ​​fixation provides extra safety. By restricting the state switching of the second latch 221, accidental loosening is effectively prevented. Compared to a snap-fit ​​structure without anti-loosening protection, this solution greatly improves the safety and reliability of the fixation while maintaining the convenience of quick fixation, making it particularly suitable for application environments with harsh conditions such as vibration and impact. The detachable design of the anti-loosening component 23 ensures safety without affecting normal maintenance, achieving an organic unity of safety and convenience.

[0075] like Figure 7-10 As shown, in some embodiments, the fixing mechanism 2 includes: a base 24 connected to the bracket 1; a buckle body 25 movably disposed on the base 24, the buckle body 25 having a buckling member 251 for buckling the mounting foot 41; wherein, the pressure sensor 3 is disposed at the buckling member 251 or the mounting foot 41.

[0076] In this invention, a new integrated solution for rapid fixation and status monitoring of the motor 4 is achieved through the snap-fit ​​fixing structure design of the base 24 and the snap-fit ​​body 25, combined with the integrated configuration of the pressure sensor 3. The technical principle is as follows: the base 24 is fixedly connected to the bracket 1, providing a stable installation foundation; the snap-fit ​​body 25 is movably mounted on the base 24, and the clamping member 251 clamps and fixes the motor 4 mounting foot 41; the pressure sensor 3 is located at the clamping member 251 or the mounting foot 41, monitoring the clamping force in real time during the clamping process to ensure proper fixation and continuously monitor the fixation status.

[0077] Specifically, the base 24 serves as a fixed end structure, securely connected to the bracket 1 via bolts or welding, providing a stable mounting foundation for the entire latching mechanism. The latching body 25, as a movable mechanism, is mounted on the base 24 and can switch between open and closed states. Its clamping element 251 is a functional component that directly contacts the mounting foot 41 of the motor 4, achieving fixation through mechanical clamping. The movable design of the latching body 25 simplifies the assembly and disassembly of the motor 4, allowing operators to complete fixation and release through simple opening and closing actions. Depending on specific design requirements, the pressure sensor 3 can be positioned on the clamping element 251 to directly sense the clamping force, or it can be positioned at the mounting foot 41 to sense the force applied.

[0078] In one specific embodiment, when installing a low-speed fan motor 4, the snap-fit ​​fixing provides sufficient fixing strength due to the low speed and relatively small vibration, while also being relatively inexpensive. After the operator positions the motor 4, they open the snap-fit ​​body 25, align the clamping member 251 with the motor 4 mounting foot 41, and then close the snap-fit ​​body 25. The clamping member 251 automatically clamps the mounting foot 41 to achieve fixation. The entire process requires no tools and is simple and quick to operate. The pressure sensor 3 monitors the clamping force in real time, issuing a warning when the clamping force is insufficient and an alarm when the clamping force is too large and may damage the mounting foot 41, ensuring that the fixing quality is within a reasonable range.

[0079] In this embodiment of the invention, the snap-fit ​​fixing structure provides an alternative quick fixing solution to the plug-in type. The snap-fit ​​structure achieves fixing through the clamping action of the clamping member 251, offering advantages in adaptability and cost control compared to the plug-in locking method. Especially for low-speed motors 4 or cost-sensitive applications, the snap-fit ​​solution can achieve quick fixing and status monitoring functions at a relatively low cost. The coexistence of the two fixing methods provides flexible technical choices for different application needs, enhancing the overall applicability and market competitiveness of the solution.

[0080] like Figure 9-10 As shown, in some embodiments, the clamping member 251 includes an elastic telescopic portion 2511, and the pressure sensor 3 is disposed on the elastic telescopic portion 2511.

[0081] In this invention, by designing an elastic telescopic part 2511 and integrating a pressure sensor 3 in the clamping member 251, adaptive adjustment and precise monitoring of the snap-fit ​​fixing are achieved. The technical principle is as follows: the elastic telescopic part 2511, as a key component of the clamping member 251, has elastic deformation capability and can automatically adjust the clamping state according to the shape and size of the motor 4 mounting foot 41, compensating for manufacturing errors and installation deviations; the pressure sensor 3, located in the elastic telescopic part 2511, can accurately sense the pressure changes generated by elastic deformation, providing precise data for monitoring the fixed state.

[0082] Specifically, the elastic telescopic part 2511 is made of elastic material or designed with elastic elements such as springs. During the clamping process, it can deform appropriately according to the actual situation of the mounting foot 41, ensuring sufficient clamping force while avoiding damage caused by over-clamping. This elastic design allows the buckling mechanism to adapt to mounting feet 41 of different sizes, improving the versatility of the fixing device. The pressure sensor 3 is directly mounted on the elastic telescopic part 2511, which can sense the stress changes generated by elastic deformation in real time. This stress change directly reflects the magnitude of the clamping force, providing the controller with accurate fixing status information.

[0083] In one specific embodiment, the dimensions of the mounting feet 41 may differ between different models of fan motors 4. Traditional rigid clamping parts 251 are difficult to adapt to this difference, resulting in either insufficient clamping leading to insecure fixation or excessive clamping causing damage to the mounting feet 41. By employing an elastic telescopic part 2511, when the mounting feet 41 are thicker, the elastic telescopic part 2511 undergoes greater compression deformation, automatically increasing the clamping force; when the mounting feet 41 are thinner, the elastic telescopic part 2511 undergoes less compression deformation, automatically decreasing the clamping force, thus maintaining an appropriate clamping state at all times. The pressure sensor 3 detects this deformation difference, and the controller can determine whether the current clamping state is appropriate, achieving intelligent fixation quality control.

[0084] The above technical solution still suffers from insufficient adaptability. Although it achieves rapid fixation, if the clamping component 251 adopts a rigid design, it cannot adapt to the size differences and manufacturing errors of the mounting feet 41 of different motors 4, which may lead to uneven clamping force or unreliable fixation. At the same time, the monitoring accuracy of the pressure sensor 3 will also be affected.

[0085] In this embodiment of the invention, the design of the elastic telescopic part 2511 adds adaptive adjustment capability to the snap-fit ​​fixing. Compared with the rigid clamping part 251, the elastic structure can automatically adapt to dimensional changes, ensuring that the optimal clamping state is achieved each time. The pressure sensor 3 is installed on the elastic telescopic part 2511, which can more sensitively sense pressure changes, improving monitoring accuracy and reliability. This adaptive design not only improves the versatility and reliability of the fixing device, but also provides a technical basis for accurate condition monitoring, achieving dual optimization of mechanical performance and monitoring function.

[0086] In some embodiments, the pressure sensor 3 is disposed in the force transmission path between the motor 4 and the bracket 1.

[0087] In this invention, by placing the pressure sensor 3 in the force transmission path between the motor 4 and the bracket 1, the most direct and accurate monitoring of the fixed state of the motor 4 is achieved. The technical principle is as follows: when the motor 4 is in a fixed state, its weight and various forces generated during operation are transmitted to the bracket 1 through the fixing mechanism 2, forming a clear force transmission path; the pressure sensor 3, placed in this force transmission path, can directly sense the actual force transmission state between the motor 4 and the bracket 1, obtaining the most accurate information on the fixed state, and providing the most reliable basis for judgment for the controller.

[0088] Specifically, the force transmission path refers to the force transmission path from motor 4 to bracket 1, including the transmission process of various forces such as the weight of motor 4, centrifugal force during operation, and vibration force. Pressure sensor 3 is installed at key nodes along this path, such as the connection between fixing mechanism 2 and bracket 1, and the contact point between fixing mechanism 2 and motor 4, to sense the actual force transmission situation. When motor 4 is properly fixed, the force transmission path is unobstructed, and pressure sensor 3 displays a stable pressure value; when the fixing becomes loose at a certain point, the force transmission capacity at that point decreases, and pressure sensor 3 will detect abnormal changes in the pressure value, thus accurately reflecting changes in the fixing state.

[0089] In one specific embodiment, the air conditioner fan motor 4 generates various dynamic loads such as rotational force and vibration force during operation. These loads are transmitted to the bracket 1 through the mounting feet 41 and the fixing mechanism 2. A pressure sensor 3 is placed in the force transmission path, for example, a pressure washer-type sensor is installed at the bolt connecting the fixing mechanism 2 and the bracket 1, which can monitor the working status of the entire force transmission system in real time. When a fixing bolt of a mounting foot 41 loosens, the force transmission capacity of that path decreases, and the corresponding pressure sensor 3 immediately detects the pressure reduction. The controller can accurately determine where the fixing problem has occurred, achieving precise fault location.

[0090] This application provides an air conditioner, including: a motor 4; and the motor fixing device described above.

[0091] In this invention, by applying a motor fixing device with intelligent monitoring function to air conditioner products, the intelligent upgrade of the air conditioner motor 4 fixing technology is achieved. The technical principle is as follows: As a typical household appliance, air conditioners have high requirements for the reliability and safety of motor 4 fixing, and traditional fixing methods are difficult to meet modern intelligent needs. Integrating the motor fixing device of any one of claims 1-7 into the air conditioner enables the air conditioner to have real-time monitoring and intelligent judgment capabilities for the motor 4 fixing status, greatly improving the product's technical level and reliability.

[0092] Specifically, the motor 4 (such as the fan motor 4, compressor motor 4, etc.) in the air conditioner is a core power component, and its fixing status directly affects the operating performance and safety of the air conditioner. By adopting the motor fixing device of this invention, the air conditioner not only has the traditional cooling / heating functions, but also adds an intelligent monitoring function for the fixing status of the motor 4. When an abnormality occurs in the fixing of the motor 4, the air conditioner can automatically identify it and take corresponding measures, such as reducing the operating power, issuing warnings, or shutting down for protection, to ensure user safety and equipment integrity.

[0093] In one specific embodiment, after the indoor unit fan motor 4 of a household split-type air conditioner adopts the fixing device of the present invention, the fixing status of the motor 4 can be monitored in real time during daily operation. When a fixing point becomes loose after long-term use, the pressure sensor 3 immediately detects the abnormality, the controller judges it as a minor fixing abnormality, the air conditioner automatically reduces the fan speed and displays a maintenance reminder on the display screen, allowing the user to contact after-sales service in a timely manner for handling, avoiding damage to the motor 4 or safety accidents caused by the worsening of the fixing problem. This intelligent monitoring and protection function greatly improves the user experience and product safety.

[0094] In related technologies, the motor 4 of traditional air conditioners is fixed using conventional bolts. Once fixed, changes in the fixing status cannot be monitored, and problems can only be discovered through regular maintenance inspections or after a malfunction occurs. This passive management method has significant time lag, easily causing small problems to escalate into major malfunctions, affecting the user experience, increasing maintenance costs, and potentially even creating safety hazards.

[0095] In this embodiment of the invention, the air conditioner integrates an intelligent motor 4 fixed monitoring system, achieving a technological leap from passive maintenance to active monitoring. Compared to traditional air conditioners, this solution can sense the fixed status of the motor 4 in real time, promptly detect and warn of fixing abnormalities, greatly improving the reliability and safety of the product. This intelligent upgrade not only enhances the technological content and market competitiveness of the air conditioner but also provides users with a safer and more reliable user experience, representing an important direction in the technological development of air conditioner products.

[0096] like Figure 11-12 As shown in the figure, this application embodiment provides a control method for the above-mentioned air conditioner, including the following steps:

[0097] S1. Obtain the pressure information of each mounting pin 41 of motor 4;

[0098] S2. Analyze the fixed state of motor 4 based on pressure information. When a fixed abnormality is detected, determine the fault level and execute the corresponding protection strategy according to the number and distribution characteristics of the abnormal fixed points.

[0099] In this invention, by acquiring the pressure information of each mounting foot 41 of the motor 4 and performing intelligent analysis based on abnormal characteristics, proactive identification and graded protection of motor 4 fixing abnormalities are achieved. The technical principle is as follows: real-time acquisition of pressure data from each mounting foot 41; analysis and identification of pressure abnormalities through algorithms; when a fixing abnormality is detected, calculation of the fault level based on the number and spatial distribution characteristics of the abnormal fixing points; and execution of corresponding protection strategies based on the fault level, thus achieving a technological upgrade from simple abnormality detection to intelligent graded protection.

[0100] Specifically, pressure information acquisition involves simultaneously collecting pressure data from each mounting foot 41 using multiple pressure sensors 3, forming a complete pressure distribution image. Motor 4 fixation status analysis identifies abnormal fixation points by comparing real-time pressure values ​​with the normal pressure range. The number of abnormal fixation points reflects the severity of the fixation problem, while spatial distribution characteristics reflect the fixation failure mode. Fault level determination is based on engineering experience and mechanical principles, mapping different abnormal modes to different hazard levels. The execution of corresponding protection strategies involves implementing differentiated protection measures according to the fault level, ensuring safety while avoiding over-protection.

[0101] In one specific embodiment, the air conditioner fan motor 4 has four mounting feet 41. During normal operation, the pressure values ​​of each mounting foot 41 should be within a reasonable range and relatively balanced. When the bolt of one mounting foot 41 becomes slightly loose, the controller detects a drop in pressure at that point, determines it as a single-point anomaly, classifies it as a minor fault, executes a protection strategy of reducing the speed of motor 4 and issuing a warning signal, and the air conditioner continues to run but alerts the user. When two adjacent mounting feet 41 have problems simultaneously, it is determined to be a minor fault; when two diagonally opposite mounting feet 41 have problems, it is determined to be a major fault because it will cause motor 4 to tilt and become severely unbalanced, and the unit will immediately shut down for protection. This differentiated treatment ensures that the most appropriate protection measures can be taken in different fault modes.

[0102] In related technologies, traditional motor protection methods mainly rely on simple over-limit protection based on parameters such as current and temperature. They cannot identify fixed-state anomalies, nor can they classify and handle anomalies according to their characteristics. Once an anomaly is detected, a uniform shutdown protection is often used. While this "one-size-fits-all" protection method ensures safety, it greatly reduces the availability of the equipment.

[0103] In this embodiment of the invention, fixed-state analysis based on pressure information enables accurate identification of fixed anomalies, and a differentiated intelligent processing is achieved through a graded protection strategy based on anomaly characteristics. Compared to traditional protection methods, this solution can accurately identify different anomaly patterns and adopt corresponding protection levels, maximizing equipment availability while ensuring safety. This intelligent protection strategy not only improves the reliability and security of the system but also significantly enhances the intelligence level of the equipment and the user experience.

[0104] In some embodiments, determining the fault level includes:

[0105] S21. When the number of abnormal fixed points is 1, it is judged as a minor fault, the motor speed is reduced by 4 and a warning signal is issued.

[0106] S22. When there are two abnormal fixed points, analyze the spatial distribution relationship of the abnormal points:

[0107] S221. If the faults are adjacent, they are determined to be minor faults. The speed of motor 4 is reduced and a warning signal is issued.

[0108] S222. If the fault is diagonally distributed, it is considered a severe fault, and the machine is shut down and an alarm signal is issued.

[0109] S23. When the number of abnormal fixed points is greater than 2, it is judged as a serious fault, the machine is stopped and an alarm signal is issued.

[0110] The above refers to the motor 4 with four mounting feet 41.

[0111] This invention establishes a differentiated fault classification algorithm based on the number and spatial distribution characteristics of abnormal fixed points, thereby achieving a refined fixed point anomaly handling strategy. The technical principle is as follows: a single abnormal point has a relatively small impact on the operation of motor 4, and a mild protection strategy is adopted; when there are two abnormal points, they are treated differently according to their spatial position relationship; adjacent distribution has a relatively small impact, while diagonal distribution will lead to severe torque imbalance; multiple abnormal points indicate a serious failure of the fixed system, requiring immediate shutdown for protection. This classification algorithm fully considers mechanical principles and engineering practice, achieving a scientifically sound and reasonable protection strategy.

[0112] Specifically, when there is one abnormal fixing point, motor 4 still has three fixing points for support. Although the force is uneven, it is basically stable, and this is judged as a minor fault. A strategy of reducing the speed of motor 4 and issuing a warning signal is adopted to ensure both safety and maintain operation. When there are two abnormal fixing points, the spatial distribution needs to be analyzed: if they are adjacent, motor 4 still has two diagonal points for support, which is relatively stable, and this is judged as a minor fault; if they are diagonally distributed, motor 4 only has two adjacent points for support, which will generate a severe overturning moment, and this is judged as a severe fault, requiring immediate shutdown and an alarm signal. When there are more than two abnormal fixing points, the fixing of motor 4 has seriously failed, and this is judged as a severe fault, requiring immediate shutdown and an alarm.

[0113] In one specific embodiment, during operation of the four-legged fixed fan motor 4, if the left front mounting foot 41 becomes loose (single-point abnormality), although the force is uneven, the motor 4 can still operate stably. The system reduces the speed to 80% of the rated speed and displays a maintenance reminder, allowing the user to arrange maintenance at their convenience. If the two diagonally opposite mounting feet 41 on the left front and right rear become loose simultaneously (diagonally distributed), the motor 4 will experience severe swaying and vibration. The system will immediately stop and issue a fault alarm to prevent damage to the motor 4 or a safety accident. If the two adjacent mounting feet 41 on the left front and left rear become loose (adjacently distributed), the motor 4 will tilt to the left but will still be supported by two points on the right. The system will reduce its speed and issue a warning, giving the user time to handle the situation.

[0114] In some embodiments, it also includes:

[0115] S3. Monitor the dynamic changes in pressure information at each mounting foot 41 of motor 4;

[0116] S4. When the fluctuation amplitude of the pressure information exceeds the preset threshold, it is determined to be an abnormal vibration.

[0117] S5. Adjust the operating parameters of motor 4 to optimize vibration characteristics.

[0118] In this invention, vibration anomalies are identified by monitoring the dynamic changes in pressure information, and vibration is controlled by actively adjusting the operating parameters of motor 4, achieving a technological breakthrough from passively bearing vibration to actively controlling it. The technical principle is as follows: vibration of motor 4 causes periodic fluctuations in pressure at each mounting foot 41. Vibration anomalies can be identified by analyzing the dynamic changes in pressure information. When a vibration anomaly is detected, the vibration characteristics are altered by adjusting operating parameters such as the speed of motor 4, avoiding resonance points or reducing excitation force, thereby improving the vibration condition at its root.

[0119] Specifically, the dynamic change characteristics of pressure information refer to the pattern of pressure value change over time. During normal operation, the pressure value is relatively stable, while abnormal vibrations will exhibit obvious periodic fluctuations. Vibration anomalies are determined by analyzing the amplitude and frequency characteristics of pressure fluctuations; when the fluctuation exceeds a preset threshold, it is considered abnormal. Adjusting the operating parameters of motor 4 mainly involves changing the rotational speed, as vibration characteristics differ at different speeds, and speed adjustment can avoid resonance points. The setting of preset thresholds needs to consider the specific characteristics of motor 4 and the application environment to ensure timely detection of anomalies without generating false alarms.

[0120] In one specific embodiment, when the air conditioner fan is running at a certain speed, an imbalance may occur due to dust accumulation or minor damage to the fan blades. The pressure sensors 3 at each mounting foot 41 detect significant periodic fluctuations, with the pressure fluctuation amplitude reaching 15%, exceeding the preset threshold of 10%. The controller then determines this as abnormal vibration. The system first attempts to adjust the speed from 1200 rpm to 1100 rpm and re-detects the vibration. If the fluctuation amplitude drops below 8%, the system operates at the new speed. If the vibration still exceeds the limit, the speed is adjusted until a suitable operating point is found. This proactive vibration control method effectively avoids damage to the motor 4 and the entire unit caused by long-term abnormal vibration.

[0121] In some embodiments, the dynamic change characteristics of monitored pressure information include:

[0122] S31. Collect pressure information within a preset time range and calculate the fluctuation range of the pressure information.

[0123] This invention implements a simple and effective vibration anomaly identification algorithm by collecting pressure information and calculating the fluctuation amplitude within a preset time range. The technical principle is as follows: pressure data from each mounting foot 41 is continuously collected within a specified time window; the fluctuation amplitude of the pressure value is calculated through statistical analysis; and when the fluctuation amplitude exceeds a preset threshold, it is determined to be a vibration anomaly. This time-window-based statistical analysis method can effectively filter out occasional pressure fluctuations and accurately identify persistent vibration anomalies.

[0124] Specifically, the preset time range refers to the time window used for data acquisition and analysis, typically set to a few seconds to tens of seconds, ensuring both data sufficiency and timely response. Pressure information is acquired by continuously sampling at a fixed frequency using pressure sensor 3 to obtain the pressure change sequence within that time period. The fluctuation amplitude is calculated by analyzing the pressure change sequence using statistical methods to determine characteristic parameters reflecting the degree of vibration, such as the difference between the maximum and minimum values, and the standard deviation. The preset threshold is a judgment standard determined based on the pressure fluctuation characteristics under normal operating conditions.

[0125] In one specific embodiment, the system sets a 10-second detection time window and collects pressure data from each mounting pin 41 at a frequency of 100Hz, obtaining 1000 data points every 10 seconds. Statistical analysis is performed on these 1000 data points, and the difference between the maximum and minimum values ​​is calculated as the fluctuation amplitude. During normal operation, due to the stability of motor 4, pressure fluctuations are minimal, typically within 5%. When abnormal vibration occurs, the pressure exhibits significant periodic changes, with fluctuation amplitudes potentially exceeding 20%. The system sets a threshold of 10%; when a fluctuation amplitude exceeding 10% is detected, it is immediately identified as an abnormal vibration, triggering subsequent adjustment and control procedures.

[0126] In some embodiments, adjusting the operating parameters of motor 4 includes:

[0127] After S51 detects abnormal vibration, it adjusts the speed of motor 4 while meeting the air volume requirements, and records the number of faults.

[0128] S52. Reassess the vibration status of motor 4. If the abnormal vibration persists, repeat the above speed adjustment.

[0129] S53. If the abnormal vibration is eliminated, the fault count is reset to zero, and motor 4 will run at this speed.

[0130] S54. When the number of failures reaches the preset limit, perform a protective shutdown.

[0131] In this invention, a balance between vibration control and functional requirements is achieved by establishing a motor 4 operating parameter adjustment mechanism under the constraint of airflow demand. The technical principle is as follows: upon detecting abnormal vibration, the motor 4 speed is adjusted while meeting the airflow demand of the air conditioner. Ineffective repeated adjustments are avoided by recording the number of faults. The adjustment effect is reassessed based on the vibration status. When the number of faults reaches the upper limit, a protective shutdown is executed, forming a complete closed-loop control strategy.

[0132] Specifically, airflow demand constraint means that the cooling / heating demand of the air conditioner must be considered when adjusting the speed; the airflow should not be excessively reduced to eliminate vibration, thus affecting the air conditioning effect. Motor speed adjustment is the main means of vibration control, avoiding resonance points or reducing unbalanced excitation by changing the speed. Fault count recording is to avoid infinite loop adjustments; if the vibration is still abnormal after each adjustment, a fault is recorded. Vibration state reassessment is to verify the effect of the adjustment and determine whether the vibration has improved. Fault count reset is to reset the counter after the vibration is eliminated, preparing for the next anomaly detection. Protective shutdown is the final protection measure when multiple adjustments are ineffective.

[0133] In one specific embodiment, the air conditioner needs to maintain a certain airflow to ensure cooling effect in cooling mode. When abnormal vibration is detected, the system first calculates the minimum allowable speed under the current operating conditions, and then adjusts the speed within this constraint range. For example, if the current speed is 1200 rpm and the minimum allowable speed is 1000 rpm, the system first tries to adjust to 1100 rpm and detects the vibration. If it is still abnormal, it adjusts to 1050 rpm and detects again. If the vibration disappears at 1000 rpm, the system operates at this speed and resets the fault count. If the vibration still exists even when the minimum allowable speed is reduced, and the number of adjustments has reached the set upper limit (e.g., 5 times), the system determines that the equipment is faulty, executes shutdown protection, and alarms.

[0134] In this embodiment of the invention, a complete vibration control strategy is established, fully considering various constraints and control requirements in practical applications. Airflow demand constraints ensure that vibration control does not affect the basic functions of the air conditioner; a fault counting mechanism avoids ineffective repeated adjustments, improving control efficiency; and the combination of self-recovery function and protective shutdown enables intelligent fault handling. Compared to simple speed regulation, this solution forms a complete closed-loop control strategy, significantly improving vibration control effectiveness, system stability, and user experience, representing an advanced level of intelligent equipment control technology.
