Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a motor mounting structure and an air conditioner. Background Technology

[0002] With the development of the times and the improvement of living standards, air conditioners have entered thousands of households and play a key role in improving people's living comfort. During the use of air conditioners, abnormal noise is a significant factor affecting user experience. The motor is a crucial component of an air conditioner, driving the fan and improving heat exchange efficiency. If the motor is not securely installed, it is prone to vibration during use. In some existing air conditioners, the motor is mounted on the bottom casing and then fixed at the top with a pressure plate, forming a limiting groove between the pressure plate and the bottom casing to restrict the motor's movement. However, this installation method cannot guarantee complete motor fixation. Over long-term use, the motor's position will gradually shift due to its own vibration. After this shift, the motor's vibration is easily transmitted to the bottom casing, producing unpleasant abnormal noise and seriously interfering with the user's environment.

[0003] Therefore, the installation method of the motor needs to be improved to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a motor mounting structure. This structure can fix the motor in the circumferential position through the cooperation of the limiting rubber ring, the bearing base, and the pressure plate, so that the motor will not vibrate or tilt, thereby eliminating the abnormal noise caused by the collision between the motor and the bottom shell, and also protecting the motor and extending its service life.

[0005] A motor mounting structure, comprising:

[0006] The support base and the pressure plate are provided, wherein the support base is provided with a placement position for placing the motor, and the pressure plate is disposed above the placement position;

[0007] A limiting rubber ring is fitted onto the outer wall of the motor. A first limiting structure is provided on the limiting rubber ring. A second limiting structure is provided on the bearing base and / or the pressure plate, which engages with the first limiting structure.

[0008] During use, this structure, through the tight engagement of the first limiting structure with the limiting rubber ring and the second limiting structure with the bearing base and pressure plate, strictly restricts the motor's circumferential position when it vibrates during operation, preventing skew. This limiting structure effectively avoids abnormal noise caused by the motor colliding with the base shell due to vibration, greatly improving the quietness of the air conditioner and creating a quieter and more comfortable operating environment for users. Because the motor is stably fixed in the mounting structure, unnecessary vibration and displacement are reduced, decreasing wear and fatigue damage to internal motor components. This significantly reduces the motor's failure rate, effectively extending its service life and lowering maintenance costs and replacement frequency for users.

[0009] In a preferred embodiment of this invention, the limiting rubber ring has an installation opening in the middle, the motor is sleeved in the installation opening, and there is an interference fit between the motor and the installation opening.

[0010] In a preferred embodiment of this utility model, two first limiting structures are provided around the limiting rubber ring, and the second limiting structures are provided on both the bearing substrate and the pressure plate. The two first limiting structures are respectively engaged with the second limiting structures on the bearing substrate and the second limiting structures on the pressure plate.

[0011] In a preferred embodiment of this invention, a plurality of limiting rubber rings are provided on the outer wall of the motor, and the plurality of limiting rubber rings are arranged in parallel along the axis of the motor.

[0012] By setting two first limiting structures on the limiting rubber rings and ensuring that the bearing base and pressure plate both mate with them, and by setting multiple limiting rubber rings along the motor axis, the number of fixing points for the motor in both the circumferential and axial directions is greatly increased. When this motor is used in air conditioners, it can be more securely restrained in its installation position during air conditioner operation, regardless of the direction of vibration or external force interference, effectively preventing motor displacement and skewness, further reducing the possibility of abnormal noise caused by collisions between the motor and surrounding components, and improving the overall operational stability and reliability of the air conditioner.

[0013] In a preferred embodiment of this invention, the first limiting structure protrudes outward from the outer wall of the limiting rubber ring, and the minimum distance H between the top of the first limiting structure and the outer wall of the limiting rubber ring is 1cm-3cm.

[0014] The second objective of this utility model is to provide an air conditioner, including a bottom shell, in which the motor mounting structure described above is located.

[0015] In a preferred embodiment of this utility model, the placement position is located in the bottom shell, and the bottom shell is provided with a first limiting groove and a second limiting groove. The first limiting groove is located on one side of the second limiting groove, and the motor is placed on the first limiting groove and the second limiting groove. The second limiting groove is provided with a second limiting structure.

[0016] The air conditioner of this application further improves the installation accuracy and stability of the motor in the bottom casing by setting a dedicated first and second limiting groove in the bottom casing, combined with a unique second limiting structure. During air conditioner operation, the motor can be more firmly fixed in the bottom casing, greatly reducing displacement and skew caused by motor vibration, effectively reducing the possibility of abnormal noise caused by collision between the motor and the bottom casing, improving the smoothness and quietness of the air conditioner's operation, and providing users with a more comfortable operating environment.

[0017] In a preferred embodiment of this invention, a wire-locking rib is provided on the bottom shell, the wire-locking rib is located on one side of the placement position, a rubber sleeve is snapped onto the wire-locking rib, and the rubber sleeve is provided with a wire-passing hole.

[0018] The design of the cable retaining ribs on the bottom shell, in conjunction with the rubber sleeve, provides reliable fixation and protection for the motor cables. Compared to traditional motor cable arrangements, this effectively prevents the motor cables from shifting or moving unnecessarily, reducing the risk of wear and breakage due to long-term vibration.

[0019] In a preferred embodiment of this utility model, the bottom shell is provided with a wire outlet, and a plurality of wire pressing ribs are provided between the wire outlet and the wire clamping rib. Each wire pressing rib forms a wire pressing position with the bottom shell, and the wire pressing ribs are arranged at intervals on the bottom shell.

[0020] The cooperation of the wire clamps and wire retainers allows the motor wires to be fully positioned in terms of height and length when the motor is installed in the placement position. This fixes the motor wires as a whole to prevent them from vibrating due to motor vibration, and ultimately eliminates abnormal noise.

[0021] In a preferred embodiment of this invention, the bottom shell is further provided with a plurality of ventilation openings, which are located on one side of the placement position.

[0022] The motor is installed in the designated location. When the motor is running, the heat generated can be quickly dissipated through the ventilation openings, maintaining the motor within a suitable operating temperature range.

[0023] The beneficial effects of this utility model are as follows:

[0024] This utility model provides a motor mounting structure, which includes a supporting base, a pressure plate, and a limiting rubber ring. The supporting base has a placement position for placing the motor, and the pressure plate is positioned above the placement position. The limiting rubber ring is fitted onto the outer wall of the motor and has a first limiting structure. The supporting base and / or the pressure plate has a second limiting structure that engages with the first limiting structure. The first limiting structure can be two radially symmetrical protrusions on the limiting rubber ring, while the second limiting structure is a groove on the supporting base and the pressure plate. During use, the limiting rubber ring is tightly fitted onto the outer wall of the motor, ensuring the protrusions are accurately positioned. Then, the motor is placed on the placement position of the supporting base, so that the protrusions of the limiting rubber ring are initially aligned with the groove of the supporting base. The motor is gently pressed down, causing the protrusions to partially engage with the groove. Next, the pressure plate is placed above the motor, and its position is adjusted so that the groove on the pressure plate is completely aligned with the protrusions of the limiting rubber ring. Finally, the pressure plate is fixed to the supporting base with bolts, at which point the motor is firmly fixed in the circumferential direction. This structure, through a tight fit between the first limiting structure of the limiting rubber ring and the second limiting structure of the supporting base and pressure plate, strictly restricts the motor's circumferential position when it vibrates during operation, preventing it from tilting. This limiting structure effectively avoids abnormal noises caused by the motor colliding with the base shell due to vibration, greatly improving the quietness of the air conditioner and creating a quieter and more comfortable operating environment for users. Because the motor is stably fixed in the mounting structure, unnecessary vibration and displacement are reduced, decreasing wear and fatigue damage to internal motor components. This significantly reduces the motor's failure rate, effectively extending its service life and lowering maintenance costs and replacement frequency for users.

[0025] This application also provides an air conditioner including the aforementioned motor mounting structure, which reduces motor noise during operation, resulting in lower overall operating noise and improved user experience. Furthermore, it reduces motor failure rate, enhancing the air conditioner's operational stability and safety. Attached Figure Description

Detailed Implementation

[0036] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0037] With the development of the times and the improvement of living standards, air conditioners have entered thousands of households and play a key role in improving people's living comfort. During the use of air conditioners, abnormal noise is a significant factor affecting user experience. The motor is a crucial component of an air conditioner, driving the fan and improving heat exchange efficiency. If the motor is not securely installed, it is prone to vibration during use. In some existing air conditioners, the motor is mounted on the bottom casing and then fixed at the top with a pressure plate, forming a limiting groove between the pressure plate and the bottom casing to restrict the motor's movement. However, this installation method cannot guarantee complete motor fixation. Over long-term use, the motor's position will gradually shift due to its own vibration. After this shift, the motor's vibration is easily transmitted to the bottom casing, producing unpleasant abnormal noise and seriously interfering with the user's environment.

[0038] Based on this, this application provides a motor mounting structure.

[0039] Example 1

[0040] See Figures 1-2 This embodiment provides a motor mounting structure, including:

[0041] The support base 1 and the pressure plate 2 are provided. The support base 1 is provided with a placement position for placing the motor 4, and the pressure plate 2 is disposed above the placement position.

[0042] A limiting rubber ring 3 is sleeved on the outer wall of the motor 4. A first limiting structure 31 is provided on the limiting rubber ring 3. A second limiting structure 11 that engages with the first limiting structure 31 is provided on the bearing base 1 and / or the pressure plate 2.

[0043] Specifically, the limiting rubber ring 3 of this application is made of wear-resistant and aging-resistant rubber material, and its first limiting structure 31 is designed as two radially symmetrical protrusions. The second limiting structure 11 on the bearing substrate 1 and the pressure plate 2 is a groove that matches the protrusions.

[0044] The limiting rubber ring 3 has an installation port in the middle, and the motor 4 is sleeved in the installation port with an interference fit between the motor 4 and the installation port. The interference fit between the installation port and the outer wall of the motor 4 ensures that the limiting rubber ring 3 is not easy to move after it is sleeved on the motor 4, so that the limiting rubber ring 3, together with the bearing base 1 and the pressure plate 2, can limit the motor 4.

[0045] During use, this structure, through the tight engagement of the first limiting structure 31 of the limiting rubber ring 3 with the second limiting structure 11 of the bearing base 1 and the pressure plate 2, strictly restricts the motor's circumferential position when it vibrates during operation, preventing it from tilting. This limiting structure effectively avoids abnormal noise caused by the motor colliding with the base shell 10 due to vibration, greatly improving the quietness of the air conditioner and creating a quieter and more comfortable operating environment for users. Because the motor is stably fixed in the mounting structure, unnecessary vibration and displacement are reduced, decreasing wear and fatigue damage to internal motor components. This significantly reduces the motor's failure rate, effectively extending its service life and lowering maintenance costs and replacement frequency for users.

[0046] In one embodiment, the limiting rubber ring 3 is provided with a first limiting structure 31, and the bearing substrate 1 is provided with a second limiting structure 11 adapted to the first limiting structure 31.

[0047] In another embodiment, the limiting rubber ring 3 is provided with a first limiting structure 31, and the pressure plate 2 is provided with a second limiting structure 11 adapted to the first limiting structure 31.

[0048] In another embodiment, the limiting rubber ring 3 is provided with two first limiting structures 31, and the bearing substrate 1 and the pressure plate 2 are both provided with second limiting structures 11 that are adapted to the first limiting structures 31.

[0049] Example 2

[0050] This embodiment is an optimization based on embodiment 1.

[0051] See Figures 1-2 In this embodiment, a specific implementation of setting two first limiting structures 31 is provided.

[0052] Specifically, two first limiting structures 31 are provided around the limiting rubber ring 3, and the second limiting structures 11 are provided on both the bearing substrate 1 and the pressure plate 2. The two first limiting structures 31 are respectively engaged with the second limiting structures 11 on the bearing substrate 1 and the second limiting structures 11 on the pressure plate 2.

[0053] In this embodiment, the limiting rubber ring 3 is made of a special fluororubber, which possesses excellent high-temperature resistance, oil resistance, and aging resistance. Two first limiting structures 31 are provided around the periphery of the limiting rubber ring 3, and the two first limiting structures 31 are symmetrically distributed at 180 degrees. Specifically, the first limiting structure 31 can be a protrusion with a trapezoidal cross-section, or it can be a dovetail block. The second limiting structure 11 is adapted to the first limiting structure 31.

[0054] Furthermore, several limiting rubber rings 3 are provided on the outer wall of the motor, and the several limiting rubber rings 3 are arranged in parallel along the axis of the motor.

[0055] For example, three limiting rubber rings 3 are provided on the outer wall of the motor, and the distance between adjacent limiting rubber rings 3 is 30mm. During the installation process, firstly, the three limiting rubber rings 3 are tightly fitted onto the outer wall of the motor in sequence, ensuring that the first limiting structure 31 of each limiting rubber ring 3 is accurately positioned. Then, the motor is placed on the placement position of the bearing base 1, so that the bottom first limiting structure 31 of the limiting rubber ring 3 is initially aligned with the second limiting structure 11 on the bearing base 1 and gently inserted partially. Next, the pressure plate 2 is slowly placed above the motor, and the position is adjusted so that the second limiting structure 11 on the pressure plate 2 is completely aligned with the top first limiting structure 31 of the limiting rubber ring 3. By evenly tightening the fastening bolts on the pressure plate 2, the first limiting structure 31 of the three limiting rubber rings 3 is tightly engaged with the second limiting structure 11 on the bearing base 1 and the pressure plate 2 respectively, completing the installation of the motor.

[0056] By setting two first limiting structures 31 on the limiting rubber ring 3, and ensuring that the bearing base 1 and pressure plate 2 both cooperate with them, and by setting multiple limiting rubber rings 3 along the motor axis, the number of fixing points of the motor in the circumferential direction is greatly increased. When this motor is used in an air conditioner, during the operation of the air conditioner, regardless of the direction of vibration or external force interference, the motor can be more stably restricted in the installation position, effectively preventing motor displacement and skewness, further reducing the possibility of abnormal noise caused by the motor colliding with surrounding components, and improving the overall operational stability and reliability of the air conditioner.

[0057] Example 3

[0058] This embodiment is an optimization based on embodiment 2.

[0059] See Figures 1-2 In this embodiment, the first limiting structure 31 protrudes outward from the outer wall of the limiting rubber ring 3, and the minimum distance H between the top of the first limiting structure 31 and the outer wall of the limiting rubber ring 3 is 1cm-3cm.

[0060] Specifically, the limiting ring 3 is made of highly elastic and fatigue-resistant silicone rubber. A first limiting structure 31 protrudes outward from the outer wall of the limiting ring 3. Its cross-section is trapezoidal, with the lower base of the trapezoid being 2cm long and the upper base being 1cm wide. The height ensures that the minimum distance between the upper base and the outer wall of the limiting ring 3 is 2cm. The corresponding second limiting structure 11 on the bearing base 1 and the pressure plate 2 is a trapezoidal groove with a matching size and the same depth as the first limiting structure 31. The groove can also have tiny venting grooves to facilitate air discharge during the clamping process, making the clamping tighter.

[0061] Two limiting rubber rings 3 are evenly distributed along the motor axis, with a spacing of 40mm between adjacent limiting rubber rings 3. During installation, first accurately fit the limiting rubber rings 3 onto the outer wall of the motor, ensuring the first limiting structure 31 is in the correct position. Place the motor into the support base 1, allowing the bottom first limiting structure 31 of the limiting rubber rings 3 to initially engage with the second limiting structure 11 of the support base 1. Then place the pressure plate 2, aligning the top first limiting structure 31 of the limiting rubber rings 3 with the second limiting structure 11 of the pressure plate 2, and tighten the fixing bolts of the pressure plate 2 to complete the installation.

[0062] Example 4

[0063] See Figures 1-8 This embodiment provides an air conditioner, including a bottom shell 10, in which a motor mounting structure as described above is installed.

[0064] Specifically, in this embodiment, the placement position is located in the bottom shell 10, and the bottom shell 10 is provided with a first limiting groove 103 and a second limiting groove 102. The first limiting groove 103 is located on one side of the second limiting groove 102, and the motor is placed on the first limiting groove 103 and the second limiting groove 102. The second limiting groove 102 is provided with a second limiting structure 11.

[0065] Specifically, the bottom shell 10 of the air conditioner is injection molded from high-strength engineering plastic, possessing excellent mechanical properties and stability. The supporting substrate 1 in Embodiment 1 can be the bottom shell 10 of the air conditioner of this application.

[0066] Inside the bottom shell 10, a position for placing the motor is designed. The first limiting groove 103 and the second limiting groove 102 are machined by a mold. The first limiting groove 103 is a semi-circular groove used to initially accommodate the bottom of the motor and ensure the basic horizontal positioning of the motor. The second limiting groove 102 is located on one side of the first limiting groove 103, and it is provided with a second limiting structure 11 that matches the first limiting structure 31 of the limiting rubber ring 3. The second limiting structure 11 is a trapezoidal protrusion. The surface of the second limiting structure 11 can also be frosted to enhance the friction and engagement stability with the first limiting structure 31.

[0067] During motor installation, the motor with the limiting rubber ring 3 is placed into the first limiting groove 103 and the second limiting groove 102 of the base shell 10, so that the first limiting structure 31 of the limiting rubber ring 3 is tightly engaged with the trapezoidal protrusion in the second limiting groove 102, thereby achieving precise circumferential positioning of the motor in the base shell 10. It should be noted that when the motor is placed in the first limiting groove 103 and the second limiting groove 102, the motor axis can be parallel to the horizontal plane.

[0068] In this embodiment, a wire-locking rib 105 is provided on the bottom shell 10. The wire-locking rib 105 is located on one side of the placement position. A rubber sleeve 107 is snapped onto the wire-locking rib 105. The rubber sleeve 107 is provided with a wire-passing hole.

[0069] On the bottom shell 10, on one side of the placement position, a wire-holding rib 105 is provided. This wire-holding rib 105 can be integrally formed with the bottom shell 10, or it can be formed using a stamping process. The wire-holding rib 105 has good elasticity and strength. The rubber sleeve 107 is made of aging-resistant, highly elastic rubber material. Its wire-passing hole diameter is designed according to the specifications of the motor wire 41, ensuring that the motor wire 41 can pass through smoothly while also providing a certain degree of clamping and fixing. The rubber sleeve 107 is tightly engaged with the wire-holding rib 105, and the motor wire 41 passes through the wire-passing hole of the rubber sleeve 107, effectively limiting the shaking and displacement of the motor wire 41 and preventing the motor wire from colliding with the bottom shell 10 or other components due to vibration during air conditioner operation, thus avoiding abnormal noise.

[0070] The cleaving design of the wire clamping rib 105 on the bottom shell 10 and the rubber sleeve 107 provides reliable fixation and protection for the motor wires. Compared with traditional motor wire arrangement methods, it effectively prevents the motor wires from shaking and shifting randomly, reducing the risk of wear and breakage caused by long-term vibration. It ensures that the electrical connection between the motor and the electrical box remains stable and reliable, improving the electrical safety and stability of the air conditioner, reducing the repair rate caused by motor wire failures, and extending the service life of the air conditioner.

[0071] In this embodiment, the bottom shell 10 is provided with a cable outlet 104, and a plurality of cable clamping ribs 106 are provided between the cable outlet 104 and the cable clamping rib 105. Each cable clamping rib 106 forms a cable clamping position 1061 with the bottom shell 10, and the cable clamping ribs 106 are arranged at intervals on the bottom shell 10.

[0072] Furthermore, the wire clamping rib 106 is located at the bottom of the inner wall of the bottom shell 10, and the wire clamping position 1061 in the wire clamping rib 106 is used to fix the height of the motor 4 wire. The wire retaining rib 105, in conjunction with the rubber sleeve 107, is used to fix the length of the motor 4 wire. The cooperation of the wire clamping rib 106 and the wire retaining rib 105 allows the motor 4 wire to be completely positioned in terms of height and length when the motor 4 is installed in the placement position, thereby fixing the motor 4 wire as a whole to prevent motor 4 wire vibration caused by motor 4 vibration, and ultimately eliminating abnormal noise.

[0073] Furthermore, the rational layout of the wire clamping rib 106, the wire outlet 104, and the wire retaining rib 105 makes the wiring of the motor's four wires neater and more orderly. Compared to traditional wiring methods, this reduces the possibility of messy distribution and tangling of the motor's four wires, facilitating installation and maintenance, improving production and after-sales maintenance efficiency, and enhancing the overall aesthetics of the product. Through more secure fixing and optimized wiring of the motor's four wires, electrical faults and mechanical wear that may be caused by loosening or displacement of the motor's four wires are reduced.

[0074] In this embodiment, the bottom shell 10 is also provided with a plurality of ventilation openings 101, which are located on one side of the placement position.

[0075] Specifically, in practical applications, the edges of each vent 101 are rounded to effectively reduce airflow resistance. The design of the vent 101 is necessary to ensure smooth airflow and improve ventilation efficiency. The motor 4 is mounted in its placement position, and when the motor 4 is running, the heat generated can be quickly dissipated through the vent 101, maintaining the motor 4 within a suitable operating temperature range.

[0076] Compared to situations with no vents 101 or improperly positioned vents 101, the design of multiple vents 101 located on one side of the placement position significantly improves the heat dissipation of the motor 4. During air conditioner operation, the heat generated by the motor 4 can be promptly carried away by the flowing air, effectively reducing the temperature of the motor 4 and preventing problems such as performance degradation and shortened lifespan due to overheating. This improves the reliability and stability of the motor 4 and ensures the stable operation of the entire air conditioning system.
