Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0047] This application provides a motor mounting base and a duct air conditioner to solve the problem of motor axial movement tearing the base. The following description is in conjunction with the accompanying drawings.

[0048] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the motor mounting bracket includes:

[0049] The base 1 includes a first support part 11 and a second support part 12, which respectively support the first end 31 and the second end 32 of the motor 3;

[0050] The limiting member 2 includes a first limiting part 21, a second limiting part 22, and a connecting part (not shown in the figure) located between the first limiting part 21 and the second limiting part 22. The first limiting part 21 and the first support part 11 cooperate to fix the first end 31, and the second limiting part 22 and the second support part 12 cooperate to fix the second end 32.

[0051] The connecting part is provided with a raised first rib 231, at least a portion of which is located in the radial direction of the motor 3.

[0052] It should be noted that the first end 31 and the second end 32 of motor 3 refer to the two ends of the motor shaft 3 in the upward direction. Here, motor 3 can refer to a dual-shaft motor 3 with two motor shafts, or a single-shaft motor 3 with only one motor shaft. For a dual-shaft motor 3, the two output shafts are coaxial, and the motor shaft axis has only one direction. The first end 31 and the second end 32 of the dual-shaft motor 3 refer to the two ends of the two output shafts extending out of the motor body 3. For a single-shaft motor 3, the first end 31 and the second end 32 are respectively the ends of the output shaft extending out of the motor body 3 and the ends of the motor body 3. The motor mounting base can be used to mount the motor 3 that drives the impeller to rotate; this impeller can be a type of impeller used in ductwork machines.

[0053] Based on the above description of the limiting member 2, it can be imagined that the limiting member 2 should be a ring-shaped structure. The part of the motor 3 located between its first end 31 and second end 32 is located between the first support part 11 and the second support part 12 and inside the ring of the limiting member 2. The protruding first rib 231 refers to the first rib 231 protruding from the connecting part, or at least protruding from the surface on which the first rib 231 is connected to the connecting part, so as to increase the thickness of the limiting member 2.

[0054] The first limiting part 21 and the first supporting part 11 cooperate in such a way that they form a connection to fix the first end 31 between them. Similarly, the second limiting part 22 and the second supporting part 12 cooperate.

[0055] It is understandable that by providing a raised first rib 231 on the connecting part and making at least a portion of the first rib 231 located in the radial direction of the motor 3, the width of the connecting part along the axial direction of the motor 3 is increased, thereby improving the strength of the limiting member 2 along the axial direction of the motor 3 and reducing the risk of the connecting part cracking under the action of the axial force of the motor 3.

[0056] In some embodiments, such as Figure 2 , Figure 7 as well as Figure 8 As shown, the two ends of the first rib 231 are located on the axial direction of the motor 3.

[0057] It should be noted that on the first rib 231, the portion away from its two ends is located in the radial direction of the motor 3, and its two ends extend to the axial direction of the motor 3. It is not difficult to imagine that the first rib 231 presents a U-shaped structure.

[0058] It is understandable that the portion of the first rib 231 extending into the axial direction of the motor 3 can improve the structural strength of the limiting member 2 in the radial direction of the motor 3, and prevent the vibration of the motor 3 during operation from tearing the first support part 11, the second support part 12, the connection between the first support part 11 and the connecting part, and the connection between the second support part 12 and the connecting part.

[0059] In some specific embodiments, the first rib 231 is located on the side of the connecting portion facing the motor 3. Generally speaking, the inner side of the retaining member 2 is more prone to cracking than the outer side of the ring. Placing the first rib 231 on the side of the connecting portion facing the motor 3 better reduces the risk of cracking of the retaining member 2.

[0060] In some embodiments, such as Figure 2 , Figure 7 as well as Figure 8 As shown, the connecting part is provided with a raised second rib 241, which is located on the side of the connecting part away from the motor 3. The first rib 231 and the second rib 241 are located on both sides of the motor 3 in the radial direction.

[0061] It should be noted that, based on the above description of the limiting member 2, it can be imagined that the limiting member 2 should be a ring-shaped structure, and the side of the connecting part away from the motor 3 refers to the outer side of the ring of the limiting member 2. The protruding second rib 241 means that the second rib 241 protrudes from the connecting part, at least from the surface on which the second rib 241 is connected to the connecting part, so as to increase the thickness of the limiting member 2.

[0062] Understandably, by setting the second rib 241 located on the outer side of the ring of the limiting member 2, not only is the structural strength of the limiting member 2 along the axial direction of the motor 3 further improved, but more space is also provided for the inner side of the ring of the limiting member 2 to accommodate the motor 3, avoiding interference between the second rib 241 and the vibration of the motor 3 during operation. At the same time, the first rib 231 and the second rib 241 located on both sides of the radial direction of the motor 3 can better enhance the overall structural strength of the limiting member 2 and extend the service life of the limiting member 2.

[0063] In some embodiments, such as Figure 2 As shown, the connecting part includes a first sub-part 23 and a second sub-part 24 that are arranged at a relative interval. The first sub-part 23 and the second sub-part 24 are connected between the first limiting part 21 and the second limiting part 22. The first sub-part 23 is provided with a protruding first rib 231, and the second sub-part 24 is provided with a protruding second rib 241.

[0064] The first sub-part 23 is provided with a fixing hole 232, which is used for fasteners to pass through and connect to the base 1.

[0065] It should be noted that the protruding first rib 231 refers to the first rib 231 protruding from the first sub-part 23, or at least protruding from the surface where the first rib 231 connects to the first sub-part 23, in order to increase the thickness of the limiting member 2. The protruding second rib 241 refers to the second rib 241 protruding from the second sub-part 24, or at least protruding from the surface where the second rib 241 connects to the second sub-part 24, in order to increase the thickness of the limiting member 2; and the second rib 241 is provided on the side of the second sub-part 24 away from the motor 3, to provide a larger receiving space for the motor 3. Fasteners are used to fasten two or more parts (or components) together into a whole. In this embodiment, the limiting member 2 and the base 1 are connected together into a whole; specifically, the fastener can be a bolt, screw, etc., and the fixing hole 232 is set as a screw hole accordingly.

[0066] It is understandable that by providing fixing holes 232 on the first sub-part 23 with the first rib 231, the installation stability of the limiting member 2, especially the first sub-part 23, can be improved, and the ability of the first sub-part 23 to resist axial movement can be enhanced. Specifically, one or more fixing holes 232 are provided, and the multiple fixing holes 232 are symmetrically arranged upward along the axis of the motor 3.

[0067] Furthermore, since the first rib 231 is configured as a U-shaped structure, and the first sub-part 23 is also configured as a U-shaped structure, it can be imagined that both ends of the first sub-part 23 are located axially upwards on the motor 3, and the fixing holes 232 can be configured as two, respectively located at the bends of the U-shaped first sub-part 23. When the motor mounting base is installed on the partition 5 of the duct machine, the first sub-part 23 is located below the second sub-part 24, so that the fasteners connecting the first sub-part 23 and the base 1 provide upward support force to better support the weight of the limiting member 2 and the motor 3.

[0068] Furthermore, a notch 242 is provided on the side of the second sub-part 24 facing away from the motor 3. When the limiting member 2 is installed on the base 1, the production personnel can observe the position of the notch 242 to determine the correct installation posture of the limiting member 2. The notch 242 is located on the outer side of the ring of the limiting member 2, which can avoid reducing the ability of the inner side of the ring of the limiting member 2 to resist the axial force of the motor 3. In addition, a second rib 241 is also provided on the side of the second sub-part 24 facing away from the motor 3, which can compensate for the reduction in the structural strength of the second sub-part 24 caused by the notch 242.

[0069] In some embodiments, such as Figure 6 , Figure 7 as well as Figure 8 As shown, the first limiting part 21 is provided with a first limiting protrusion 211, which is used to be embedded in the first end 31;

[0070] It should be noted that the first end 31 is correspondingly provided with a first groove 311 for the first limiting protrusion 211 to be inserted. It can be understood that the cooperation between the first limiting protrusion 211 and the first groove 311 reduces the vibration and movement caused by the assembly gap between the limiting member 2 and the first end 31, thereby reducing the operating noise of the motor 3.

[0071] For example, the first groove 311 can be disposed radially on the first end 31, and the first limiting protrusion 211 can be inserted into the first groove 311 radially from the motor 3 to reduce the axial movement of the motor 3. The first groove 311 can also be disposed axially on the first end 31, and the first limiting protrusion 211 can be inserted into the first groove 311 axially from the motor 3 to reduce the radial vibration of the motor 3. The first groove 311 can be disposed both radially and axially on the first end 31. Correspondingly, a portion of the first limiting part 21 should be located radially on the motor 3, and another portion should be located axially on the motor 3, so that the first limiting protrusion 211 is disposed at the corresponding position.

[0072] Specifically, at least a portion of the first limiting portion 21 protrudes in a direction close to the first end portion 31 to form a first limiting protrusion 211.

[0073] In some embodiments, such as Figure 6, Figure 7 as well as Figure 8 As shown, the second limiting part 22 is provided with a second limiting protrusion 221, which is used to be embedded in the second end 32.

[0074] It should be noted that the second end 32 is correspondingly provided with a second groove 312 for the second limiting protrusion 221 to be inserted. It can be understood that the cooperation between the second limiting protrusion 221 and the second groove 312 reduces the vibration and movement caused by the assembly gap between the limiting member 2 and the second end 32, thereby reducing the operating noise of the motor 3.

[0075] For example, the second groove 312 can be disposed radially on the second end 32, and the second limiting protrusion 221 can be inserted into the second groove 312 radially from the motor 3 to reduce the axial movement of the motor 3. The second groove 312 can also be disposed axially on the second end 32, and the second limiting protrusion 221 can be inserted into the second groove 312 axially from the motor 3 to reduce the radial vibration of the motor 3. The second groove 312 can be disposed both radially and axially on the second end 32. Correspondingly, a portion of the second limiting part 22 should be located radially on the motor 3, and another portion should be located axially on the motor 3, so that the second limiting protrusion 221 is disposed at the corresponding position.

[0076] Specifically, at least a portion of the second limiting portion 22 protrudes in a direction close to the second end portion 32 to form a first limiting protrusion 211.

[0077] In some embodiments, such as Figure 6 , Figure 7 as well as Figure 8 As shown, the first limiting part 21 is provided with a first limiting protrusion 211, which is used to be embedded in the first end 31; the second limiting part 22 is provided with a second limiting protrusion 221, which is used to be embedded in the second end 32.

[0078] It should be noted that the first end 31 is provided with a first groove 311 for the first limiting protrusion 211 to be inserted, and the second end 32 is provided with a second groove 312 for the second limiting protrusion 221 to be inserted.

[0079] It is understandable that the engagement between the first limiting protrusion 211 and the first groove 311, and the engagement between the second limiting protrusion 221 and the second groove 312, reduces the vibration and movement caused by the assembly gap between the limiting member 2 and the motor 3, thereby reducing the operating noise of the motor 3. The specific arrangement of the first limiting protrusion 211, the first groove 311, the second limiting protrusion 221, and the second groove 312 can be referred to the above embodiments, and will not be repeated here.

[0080] In some embodiments, such as Figure 1and Figure 2 As shown, the first limiting part 21 is provided with a first slot 27 and a second slot 28, and the first limiting protrusion 211 is located between the first slot 27 and the second slot 28; the second limiting part 22 is also provided with a first slot 27 and a second slot 28, and the second limiting protrusion 221 is located between the first slot 27 and the second slot 28.

[0081] The first support portion 11 is provided with a first buckle 16 and a second buckle 17, which are engaged one-to-one with the first slot 27 and the second slot 28 on the first limiting portion 21. Similarly, the second support portion 12 is provided with a first buckle 16 and a second buckle 17, which are engaged one-to-one with the first slot 27 and the second slot 28 on the second limiting portion 22. It is understood that the first buckle 16 and the second buckle 17 have different structures, and the first slot 27 and the second slot 28 have different shapes, to provide different clamping directions and clamping forces.

[0082] Specifically, the second slot 28 is larger than the first slot 27. During use of the motor mounting bracket, such as... Figure 8 As shown, the first slot 27 is located below the second slot 28. This enhances the stability of the limiting member 2 near the second sub-part 24 by the cooperation between the second slot 28 and the second buckle 17.

[0083] In some embodiments, such as Figure 2 , Figure 7 and Figure 8 As shown, the limiting member 2 also includes a first abutting part 25 and a second abutting part 26. The first abutting part 25 is connected to the first limiting part 21, and the second abutting part 26 is connected to the second limiting part 22. The first abutting part 25 and the second abutting part 26 are fixed upward along the motor 3 axis to the first end 31 and the second end 32.

[0084] It should be noted that the first blocking part 25 and the first limiting part 21 are connected to form an L-shaped whole in cross-section. Similarly, the second blocking part 26 and the second limiting part 22 are connected to form an L-shaped whole in cross-section. The first limiting part 21 and the second limiting part 22 are located radially on the first end 31 and the second end 32, respectively.

[0085] Understandably, the limiting component 2 can reduce vibration in the axial and radial directions of the motor 3, thus providing a more stable fixing effect.

[0086] Furthermore, in this embodiment, the first limiting part 21 is provided with a first limiting protrusion 211, the second limiting part 22 is provided with a second limiting protrusion 221, the first end 31 is provided with a first groove 311 in the radial direction, and the second end 32 is provided with a second groove 312 in the radial direction.

[0087] In some embodiments, the first abutment 25, the second abutment 26, the first limiting part 21, the second limiting part 22, the first sub-part 23, and the second sub-part 24 are integrally formed. In this way, the limiting member 2 is stronger, and the motor 3 is more securely fixed.

[0088] In some embodiments, such as Figure 1 , Figure 3 as well as Figure 4 As shown, the first support part 11 is provided with a third abutment part 111, and the second support part 12 is provided with a fourth abutment part 121. The third abutment part 111 and the fourth abutment part 121 fix the first end 31 and the second end 32 upward along the motor 3 axis.

[0089] It should be noted that, as Figure 4 , Figure 5 as well as Figure 6 As shown, the first support portion 11 and the second support portion 12 provide radial support from the first end portion 31 and the second end portion 32, respectively, and the third abutment portion 111 and the fourth abutment portion 121 limit the movement from the first end portion 31 and the second end portion 32, respectively. The third abutment portion 111 is located between the first latch 16 and the second latch 17 on the first support portion 11, and the fourth abutment portion 121 is located between the first latch 16 and the second latch 17 on the second support portion 12.

[0090] Understandably, the third stop 111 and the fourth stop 121 can reduce vibration in the axial direction of the motor 3, thus providing a more stable fixing effect.

[0091] In some embodiments, such as Figure 1 , Figure 3 as well as Figure 4 As shown, the base 1 also includes a seat 13 connected between the first support portion 11 and the second support portion 12. A first reinforcing rib 14 is connected between the seat 13 and the first support portion 11, and a second reinforcing rib 15 is connected between the seat 13 and the second support portion 12.

[0092] It should be noted that the base 13 connects the first support part 11 and the second support part 12 into a whole, and the first support part 11, the second support part 12, and the base 13 enclose a space for accommodating at least a portion of the motor 3. Both the first reinforcing rib 14 and the second reinforcing rib 15 are positioned towards the motor 3.

[0093] Understandably, the first reinforcing rib 14 increases the connection strength between the first support part 11 and the base body 13, and the second reinforcing rib 15 increases the connection strength between the second support part 12 and the base body 13, thereby overcoming the axial force of the motor 3 and reducing the possibility of deformation of the first support part 11 and the second support part 12.

[0094] For example, multiple first reinforcing ribs 14 are provided, and the first reinforcing ribs 14 are formed by protruding at the connection between the first support portion 11 and the base body 13 in the direction close to the motor 3. Multiple second reinforcing ribs 15 are provided, and the second reinforcing ribs 15 are formed by protruding at the connection between the second support portion 12 and the base body 13 in the direction close to the motor 3.

[0095] In some embodiments, such as Figure 1 and Figure 4 As shown, the base 13 is provided with multiple mounting holes 131 and multiple positioning holes 132. The mounting holes 131 are used for fasteners to pass through and connect to the partition 5 of the air duct machine. At least part of the hole wall of the positioning hole 132 is flat. The multiple positioning holes 132 are asymmetrically arranged.

[0096] It should be noted that the fasteners here can be the same as or different from the fasteners passing through the fixing holes 232. Multiple mounting holes 131 are used to improve the connection stability between the base 1 and the partition 5; these mounting holes 131 are screw holes.

[0097] By embedding at least a portion of the duct partition 5 into the positioning hole 132, the base 1 is pre-positioned. By making at least a portion of the hole wall of the positioning hole 132 flat, the positioning stability between the base 13 and the duct partition 5 is improved. The positioning hole 132 can be triangular, quadrilateral, pentagonal, etc. Asymmetrical arrangement of multiple positioning holes 132 means that multiple positioning holes 132 cannot form a symmetrical relationship in any direction. This is beneficial for preventing mistakes at the front end of the production cutting process. It can not only effectively realize the cutting and stamping, prevent incorrect material cutting and reverse stamping, but also greatly reduce the risk of scrap. During the production process, the positioning hole 132 can also enable production staff to quickly position and complete the assembly at that production point, improving the production efficiency of the production line.

[0098] Specifically, three positioning holes 132 are provided, and the virtual connection between the three positioning holes 132 is a triangle, which improves the stability of the pre-positioning of the base 1 and facilitates subsequent installation operations.

[0099] In some embodiments, such as Figure 4 As shown, the first support portion 11 is provided with a first protrusion 112 protruding toward the second support portion 12, and the second support portion 12 is provided with a second protrusion 122 protruding toward the first support portion 11.

[0100] Understandably, the first convex 112 and the second convex 122 respectively improve the structural strength of the first support portion 11 and the second support portion 12 along the axis of the motor 3.

[0101] In some embodiments, such as Figure 1 and Figure 4As shown, the base 1 also includes a seat 13 connected between the first support portion 11 and the second support portion 12. A first reinforcing rib 14 is connected between the seat 13 and the first support portion 11, and a second reinforcing rib 15 is connected between the seat 13 and the second support portion 12.

[0102] The first support portion 11 is provided with a first protrusion 112 protruding toward the second support portion 12, and the second support portion 12 is provided with a second protrusion 122 protruding toward the first support portion 11.

[0103] Understandably, the first reinforcing rib 14 increases the connection strength between the first support part 11 and the base body 13, the second reinforcing rib 15 increases the connection strength between the second support part 12 and the base body 13, and the first convex bulge 112 and the second convex bulge 122 respectively increase the structural strength of the first support part 11 and the second support part 12 along the axial direction of the motor 3, thereby reducing the possibility of deformation of the base 1.

[0104] This application also provides a duct air conditioner, which includes the motor mounting base described above. The specific structure of the motor mounting base is as described in the above embodiments. Since this duct air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0105] In some embodiments, such as Figure 5 and Figure 6 As shown, the ducted air conditioner also includes a motor 3, which has two output shafts. The two output shafts can drive multiple impellers in the ducted air conditioner to rotate, giving the ducted air conditioner high ventilation efficiency.

[0106] In some embodiments, such as Figure 9 and Figure 10 As shown, the duct machine also includes a volute 4 and a partition 5. The volute 4 is provided with a third buckle 41, and the partition 5 is provided with a third slot 51 and a pressure pack 52. The pressure pack 52 protrudes from the end of the slot of the third slot 51, and the third buckle 41 is engaged with the pressure pack 52 through the third slot 51.

[0107] It should be noted that the volute 4 is used to house the impeller. In related technologies, the volute 4 is usually fixed to the baffle 5 with screws. However, since the volute 4 and the baffle 5 are fixed in planar contact, and there is no other structure on the baffle 5 to fix the volute 4, if the volute 4 is not properly assembled or the design gap is too large, the volute 4 will move relative to the baffle 5 during the operation of the ducted air conditioner, resulting in excessive vibration of the volute 4 and noise. Furthermore, in ducted air conditioners, the baffle 5 is usually made of sheet metal. Sheet metal parts refer to the products of comprehensive cold working processes for thin metal sheets (usually less than 6mm), including a series of operations such as shearing, punching / cutting / composite, bending, welding, riveting, splicing, and forming. Therefore, the baffle 5 itself is relatively thin. In this embodiment, by setting a pressure pack 52 at the end of the groove of the third slot 51 of the partition 5, not only is the structural strength of the part that engages with the third buckle 41 improved, but compared with the third buckle 41 being directly engaged at the end of the groove of the third slot 51, the engagement gap is also reduced, and the tightness of the engagement between the third buckle 41 and the partition 5 is improved, thus fundamentally solving the problem of excessive vibration of the volute 4 and the resulting noise.

[0108] In some embodiments, such as Figure 7 and Figure 8 As shown, the duct unit also includes a top cover 6, which is perpendicular to the partition 5 and connected to the upper side of the partition 5. The first support part 11 and the second support part 12 are both connected to the top cover 6.

[0109] It is understandable that the top cover 6, the partition 5, and the motor mounting base form a triangular whole, and its stability enables the motor 3 to operate at high speeds for a long time.
