[0033] The motor mounting bracket 10 of this utility model embodiment is described below with reference to the accompanying drawings.

[0034] The motor mounting bracket 10 of this utility model embodiment includes a mounting base 100, a cover 200, and a connector 300.

[0035] The cover 200 is configured to be mounted on one side of the mounting base 100 so that a receiving space for accommodating the motor 30 is defined between the cover 200 and the mounting base 100. That is, when the cover 200 is mounted on one side of the mounting base 100, a receiving space is defined between the cover 200 and the mounting base 100.

[0036] One end of the connector 300 is connected to the mounting base 100, and the other end is connected to the cover 200. The connector 300 is configured to allow a change in the relative position between the mounting base 100 and the cover 200, so that the cover 200 can move to a mounting position on the side of the mounting base 100. That is, the connector 300 can be made of an elastic, deformable material, and when the cover 200 moves relative to the cover 200, the connector 300 will bend, so that the cover 200 can move to a mounting position on the side of the mounting base 100. Alternatively, the connector 300 may also include multiple connecting segments, with adjacent connecting segments rotatably connected, for example, adjacent connecting segments hinged together, and when the cover 200 moves relative to the cover 200, the connector 300 will also bend, so that the cover 200 can move to a mounting position on the side of the mounting base 100.

[0037] Compared with related technologies, in this embodiment of the motor mounting bracket 10, the cover 200 and the mounting base 100 are connected by a connector 300, and the connector 300 allows for changes in the relative position between the mounting base 100 and the cover 200. By using the connector 300 to connect the cover 200 and the mounting base 100 as a single unit, it is unnecessary to separately handle and assemble the cover and base during the assembly of the motor mounting bracket 10. This significantly reduces the time required for assembling the motor mounting bracket 10, thus improving the assembly efficiency of the motor mounting bracket 10 in this embodiment of the invention.

[0038] In some embodiments, such as Figures 2-6 As shown, the connector 300 includes a first connecting portion 310, a second connecting portion 320, and a third connecting portion 330. One end of the first connecting portion 310 is connected to the mounting base 100, and one end of the second connecting portion 320 is connected to the cover 200. One end of the third connecting portion 330 is connected to the other end of the first connecting portion 310; the other end of the third connecting portion 330 is connected to the other end of the second connecting portion 320.

[0039] The first connecting portion 310, the third connecting portion 330, and the first connecting portion 310 are all sheet-like. That is, the connector 300 can be made of a deformable material, such as polycarbonate plastic, iron sheet, or copper sheet. Since the first connecting portion 310, the first connecting portion 310, and the third connecting portion 330 are all sheet-like with a small thickness, when the connector 300 is subjected to external force, the first connecting portion 310, the first connecting portion 310, and the third connecting portion 330 are more likely to bend. This makes it easier for the operator to move the cover 200 to the mounting position on the side of the mounting base 100, thus improving the practicality of the motor mounting bracket 10 of this utility model embodiment.

[0040] Furthermore, the thicknesses of the first connecting portion 310 and the second connecting portion 320 are both greater than the thickness of the third connecting portion 330. The first connecting portion 310 and the second connecting portion 320 are the parts that connect the connector 300 to the cover 200 and the mounting base 100. The greater thickness of the first connecting portion 310 and the second connecting portion 320 compared to the third connecting portion 330 allows for a more secure connection between the connector 300 and the cover 200 and the mounting base 100. Moreover, the thinner thickness of the third connecting portion 330 makes it easier to bend.

[0041] Optionally, the ratio of the thickness of the first connecting portion 310 to the thickness of the third connecting member 300 is 1.2 to 2. Optionally, the ratio of the thickness of the first connecting portion 310 to the thickness of the third connecting member 300 is 1.3 to 1.8. Optionally, the ratio of the thickness of the first connecting portion 310 to the thickness of the third connecting member 300 is 1.5 to 1.6. On the one hand, this makes the connection between the first connecting portion 310 and the mounting base 100 more stable, while also making the third connecting portion 330 easier to bend. On the other hand, the third connecting portion 330 is thinner than the first connecting portion 310, thereby saving manufacturing material for the connecting member 300 and reducing the manufacturing cost of the motor mounting bracket 10 in this embodiment.

[0042] Optionally, the ratio of the thickness of the second connecting portion 320 to the thickness of the third connecting member 300 is 1.2 to 2. Optionally, the ratio of the thickness of the second connecting portion 320 to the thickness of the third connecting member 300 is 1.4 to 1.9. Optionally, the ratio of the thickness of the second connecting portion 320 to the thickness of the third connecting member 300 is 1.5 to 1.7. On the one hand, this makes the connection between the second connecting portion 320 and the cover 200 more stable, while also making the third connecting portion 330 easier to bend. On the other hand, the third connecting portion 330 is thinner than the second connecting portion 320, thereby saving manufacturing material for the connecting member 300 and reducing the manufacturing cost of the motor mounting bracket 10 in this embodiment.

[0043] In some embodiments, the mounting base 100, cover 200, and connector 300 are integrally injection molded. On the one hand, this eliminates the need for additional assembly or bonding, allowing the mounting base 100, cover 200, and connector 300 to be directly molded into a single unit, thereby significantly reducing labor and process costs. On the other hand, the integral molding of the mounting base 100, cover 200, and connector 300 avoids stress concentration problems caused by splicing, thus improving the bending resistance and durability of the connector 300, and extending the service life of the motor mounting bracket 10 in this embodiment.

[0044] In some embodiments, such as Figures 1-5 As shown, the mounting base 100 has one or more first through holes 110. The cover 200 has one or more second through holes 210, which correspond to the first through holes 110. The first through holes 110 and the second through holes 210 are fixedly connected by screws. That is, the mounting base 100 has second through holes 210, the cover 200 has second through holes 210, and screws are used to pass through the second through holes 210 to fix the cover 200 to the mounting base 100.

[0045] For example Figure 3 As shown, the mounting base 100 has three first through holes 110, which are spaced apart circumferentially. The cover 200 has three second through holes 210, which are also spaced apart circumferentially and correspond one-to-one with the three first through holes 110. The three first through holes 110 and the three second through holes 210 are respectively fixedly connected by three screws or three bolt assemblies.

[0046] Furthermore, at least one of the first through hole 110 and the second through hole 210 is a threaded hole.

[0047] In some embodiments, such as Figures 1-5As shown, the mounting base 100 is further provided with a first positioning structure, and the cover 200 is further provided with a second positioning structure. When the first positioning structure and the second positioning structure cooperate, the first through hole 110 corresponds to the corresponding second through hole 210. That is, the first through hole 110 and its corresponding second through hole 210 are positioned by the cooperation of the first positioning structure and the second positioning structure, thereby facilitating the connection of the first through hole 110 and the second through hole 210 with screws or bolt assemblies, so as to facilitate the installation of the mounting base 100 and the cover 200, thus further improving the installation efficiency of the motor mounting bracket 10 in this embodiment.

[0048] Specifically, the first positioning structure consists of multiple positioning grooves 120 disposed on the mounting base 100; multiple first through holes 110 are provided, each first through hole 110 being disposed on the bottom wall surface 121 of the positioning groove 120. The second positioning structure consists of multiple positioning protrusions 220 disposed on the cover 200, the multiple positioning protrusions 220 being fitted one-to-one with the multiple positioning grooves 120, and the second through holes 210 being disposed on the positioning protrusions 220.

[0049] For example Figures 3-5 As shown, the mounting base 100 is provided with three positioning grooves 120, which are spaced apart in the circumferential direction. The cover 200 is provided with three positioning protrusions 220, which are spaced apart in the circumferential direction, and the three positioning grooves 120 correspond one-to-one with the three positioning protrusions 220.

[0050] In some embodiments, such as Figures 1-5 As shown, the mounting base 100 is provided with at least one first stop plate 130, one end of the connector 300 is connected to one side of the mounting base 100, and the first stop plate 130 is located on the other side of the mounting base 100. That is, before the cover 200 is installed in the installation position, the cover 200 is positioned by at least one first stop plate 130 so that the first positioning structure and the corresponding second positioning structure can cooperate, thereby making it easier for the first through hole 110 and the corresponding second through hole 210 to align, thus further improving the installation efficiency of the motor mounting bracket 10 in this embodiment.

[0051] Furthermore, such as Figure 4As shown, the first stop plate 130 is provided with a first snap-fit ​​protrusion 140, and the cover 200 is provided with at least one second snap-fit ​​protrusion 230. The first snap-fit ​​protrusion 140 is snapped into connection with the corresponding second snap-fit ​​protrusion 230. That is, after the first stop plate 130 and the cover 200 are engaged, the cover 200 and the mounting base 100 can be snapped and fixed by the first snap-fit ​​protrusion 140 and the second snap-fit ​​protrusion 230. Thus, when the screw passes through the first through hole 110 and the second through hole 210, there is no need to manually press the cover 200 and the mounting base 100, making it easier to fix the cover 200 and the mounting base 100, and improving the practicality of the motor mounting bracket 10 in this embodiment.

[0052] In some embodiments, such as Figures 1-5 As shown, the mounting base 100 is provided with two second stop plates 150, and one end of the connector 300 is connected to one side of the mounting base 100. The two second stop plates 150 are positioned on the mounting base 100 at positions corresponding to the connector 300, and a clearance space 240 is formed between the two second stop plates 150, which is configured to allow the connector 300 to pass through. Each second stop plate 150 has a third snap-fit ​​protrusion 151 on the side closest to the other second stop plate 150. The cover 200 is also provided with two fourth snap-fit ​​protrusions 250, which are snap-fitted to the two third snap-fit ​​protrusions 151 one-to-one. In other words, after the second stop plate 150 is engaged with the cover 200, the cover 200 and the mounting base 100 can be locked together by the third locking protrusion 151 and the fourth locking protrusion 250. Thus, when the screw passes through the first through hole 110 and the second through hole 210, there is no need to manually press the cover 200 and the mounting base 100, making it easier to fix the cover 200 and the mounting base 100, and improving the practicality of the motor mounting bracket 10 in this embodiment.

[0053] The air conditioner indoor unit 40 of this utility model embodiment is described below with reference to the accompanying drawings.

[0054] like Figure 8 As shown, the indoor unit 40 of the air conditioner in this embodiment of the present invention includes a duct frame 20, a fan, and a motor mounting bracket 10. The motor mounting bracket 10 is any of the motor mounting brackets described above. The motor 30 of the fan is mounted between the cover 200 and the mounting base 100, and the mounting base 100 is mounted on the duct frame 20. The motor mounting bracket 10 is mounted on the duct frame 20 by a snap-fit ​​structure, screws, or bolts.

[0055] In this embodiment of the air conditioner indoor unit 40, the cover 200 of the motor mounting bracket 10 is connected to the mounting base 100 via a connector 300, and the connector 300 allows for changes in the relative position between the mounting base 100 and the cover 200. By using the connector 300 to connect the cover 200 and the mounting base 100 as a single unit, it is unnecessary to separately handle and assemble the cover and base during the assembly of the motor mounting bracket 10. This significantly reduces the time required for assembling the motor mounting bracket 10, thus improving the assembly efficiency of the motor mounting bracket 10 in this embodiment of the invention.

[0056] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
