Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a motor mounting structure and an air conditioner. Background Art

[0002] The air conditioner is equipped with a motor bracket and a motor cover for fixing the motor to ensure the stability of the motor during operation.

[0003] In the prior art, the motor bracket of an air conditioner such as a ducted air conditioner is assembled with a volute mounting plate or a partition through a connection structure such as a buckle or a screw to achieve a detachable connection between the motor bracket and the volute mounting plate. However, there will be some positioning errors in the assembly through the above connection structure, and it is impossible to ensure that the installation position of the motor bracket on the volute mounting plate or the partition is completely accurate. In addition, during the long-term use of the ducted air conditioner, the connection between the motor bracket and the volute mounting plate or the partition is easy to loosen. In this way, the position of the motor bracket is easy to shift, thereby affecting the coaxiality of the motor shaft and the wind wheel in the volute, and increasing the noise generated by the fan. Summary of the invention

[0004] The problem solved by the invention is: how to ensure the coaxiality between the motor shaft of the motor and the wind wheel.

[0005] To solve the above problems, the present invention provides a motor mounting structure, including a motor bracket, a motor cover and a connecting piece, wherein the motor bracket and the motor cover are detachably connected via the connecting piece, and the motor bracket is suitable for being integrally formed with a mounting plate in an air conditioner.

[0006] Therefore, by providing a motor bracket integrally formed with the mounting plate, on the one hand, the structural strength of the motor bracket is improved, and the stability of the motor in the air conditioner is ensured. On the other hand, the increased difficulty of disassembly and assembly when the motor bracket and the mounting plate are detachably connected, and the occurrence of positioning errors in assembly, etc., is avoided, and the loose connection between the motor bracket and the mounting plate due to the detachable connection is avoided during long-term use of the air conditioner, so as to prevent the position of the motor bracket on the mounting plate from being offset, thereby affecting the coaxiality of the motor shaft of the motor and the wind wheel in the volute and increasing the noise generated by the air conditioner. In this way, the installation accuracy of the motor on the mounting plate is ensured, and the coaxiality of the motor shaft of the motor and the wind wheel is ensured.

[0007] Optionally, the connecting member includes a locating pin; the locating pin is arranged on the motor bracket, and the motor cover is provided with a first locating groove, and / or the locating pin is arranged on the motor cover, and the motor bracket is provided with the first locating groove; and the locating pin is plugged into and matched with the first locating groove.

[0008] Thus, by plugging and cooperating with the locating pin and the first locating groove, a detachable connection between the motor bracket and the motor cover is achieved to fix the position of the motor in the air conditioner, thereby ensuring the installation accuracy of the motor on the mounting plate and ensuring the coaxiality of the motor shaft and the wind wheel.

[0009] Optionally, the motor bracket includes a first bracket and a second bracket arranged opposite to each other, and the first bracket and / or the second bracket is provided with the first positioning groove on the side facing the motor cover, and the positioning pin is provided at a position on the motor cover corresponding to the first positioning groove.

[0010] Therefore, the motor bracket includes a first bracket and a second bracket, and the first bracket and the second bracket are respectively arranged at the two ends of the motor in the length direction of the mounting plate, so that the connection between the motor cover and the motor bracket is located at the two ends of the motor in the length direction of the mounting plate, so as to ensure the stability when the motor is connected to the wind wheel, and to ensure the coaxiality of the motor with the wind wheel when the motor is running.

[0011] Optionally, the connecting member also includes a limit buckle; the limit buckle is arranged on the motor bracket, and the motor cover is provided with a limit groove, and / or the limit buckle is arranged on the motor cover, and the motor bracket is provided with the limit groove; and the limit buckle is engaged with the limit groove.

[0012] Therefore, by the snap-fitting cooperation between the limiting buckle and the limiting groove, a detachable connection between the motor bracket and the motor cover is achieved to fix the position of the motor in the air conditioner, thereby further ensuring the installation accuracy of the motor on the mounting plate and ensuring the coaxiality of the motor shaft and the wind wheel.

[0013] Optionally, the limiting buckle includes an integrally formed clamping portion and a limiting portion, a second positioning groove is provided in the limiting groove, and when the limiting portion is clamped into the second positioning groove, the clamping portion is clamped with the limiting groove.

[0014] Therefore, the clamping part and the limiting part of the limit buckle are integrally formed, and the limit buckle is preferably integrally formed with the motor cover (or motor bracket) to improve the structural strength of the limit buckle; the clamping part and the limiting part are both used to be clamped into the limiting groove to ensure the stability of the motor bracket and the motor cover when they are connected; and a second positioning groove is provided in the limiting groove for clamping and cooperating with the limiting part to further improve the stability of the motor bracket and the motor cover when they are connected.

[0015] Optionally, the limiting buckle further includes a toggle portion integrally formed with the clamping portion, and the toggle portion extends from one end connected to the clamping portion to outside the limiting groove.

[0016] Therefore, the toggle part is arranged at the connection between the clamping part and the limiting part, and the toggle part, the clamping part and the limiting part are integrally formed to ensure the structural strength of the limiting buckle; since the limiting buckle has a certain elasticity, and the toggle part and the clamping part are U-shaped (or V-shaped structure) as a whole, on the one hand, it is convenient for the limiting buckle to be clamped into the limiting groove, and on the other hand, it makes it easy for the limiting buckle to undergo elastic deformation when the installer presses the toggle part, thereby facilitating the limiting part to be clamped into the second positioning groove, and facilitating the limiting buckle to be disengaged from the limiting groove to release the clamping connection between the limiting part and the second positioning groove, thereby releasing the clamping connection between the limiting buckle and the limiting groove to disassemble the motor cover.

[0017] Optionally, the motor bracket further includes a connecting plate, and two ends of the connecting plate are respectively integrally formed with the first bracket and the second bracket.

[0018] Therefore, the connecting plate is arranged at the upper end and / or lower end of the first bracket and the second bracket, and the connecting plate is used to connect the ends of the first bracket and the second bracket located in the same direction; by setting the connecting plate, the structural strength of the motor bracket is enhanced, and the stability of the motor bracket when connected to the motor cover is ensured.

[0019] Optionally, the limiting groove is arranged at an end of the first bracket and / or the second bracket away from the end connected to the connecting plate, and the limiting buckle is arranged at a position on the motor cover corresponding to the limiting groove.

[0020] Therefore, the connecting plate is preferably arranged at the upper ends of the first bracket and the second bracket to avoid the situation where it is easy to hinder the installation of the motor on the motor bracket when it is arranged at the lower ends of the first bracket and the second bracket; accordingly, the limiting groove is preferably arranged at the lower end of the first bracket and / or the second bracket to facilitate the installer to insert the limiting buckle into the limiting groove or release the snap-fit ​​between the limiting buckle and the limiting groove.

[0021] Optionally, the connecting plate is located above the first bracket and the second bracket, and a first limiting surface is provided on the connecting plate, and a second limiting surface is provided on the motor cover; when the positioning pin is plugged into the first positioning groove, the first limiting surface fits with the second limiting surface.

[0022] Therefore, when the motor cover and the motor bracket are assembled, the first limiting surface abuts and fits against the second limiting surface, so that the connecting plate limits the motor cover and prevents the motor cover from moving toward the motor bracket, so as to avoid the motor being damaged or being unfavorable to the motor routing due to the motor cover pressing on the motor when the motor cover and the motor bracket are installed.

[0023] Optionally, the limiting groove is provided on one of the first bracket and the second bracket at the end away from the connection with the connecting plate, the threaded hole is provided on the other of the first bracket and the second bracket at the end away from the connection with the connecting plate, and the limiting buckle and the mounting hole are provided on the motor cover, the motor bracket and the motor cover are clamped at the limiting groove and the limiting buckle, and are suitable for being connected at the threaded hole and the mounting hole by fasteners.

[0024] Therefore, the limit clip and the threaded hole are preferably arranged at the lower end of the motor bracket to facilitate the installation personnel to operate the installation or disassembly of the motor bracket and the motor cover at the lower end of the motor mounting structure; and the limit groove and the threaded hole are respectively arranged on one of the first bracket and the second bracket to ensure the convenience of installation or disassembly of the motor bracket and the motor cover and the stability when the motor bracket and the motor cover are connected.

[0025] Optionally, the motor mounting structure also includes a limiting rib; a first opening is provided on the motor bracket, and a second opening is provided on the motor cover, and the first opening and the second opening constitute a through hole for the motor shaft of the motor to pass through; the limiting rib is arranged at the first opening and / or the second opening to limit the movement of the motor along the axial direction of the motor shaft.

[0026] Therefore, the through hole is used for the motor shaft of the motor to extend out of the motor mounting structure in the left and right directions, so as to facilitate the connection and cooperation between the motor shaft of the motor and the wind wheel; the limiting ribs are arranged on the motor bracket and / or the motor pressure cover, and are located at the end of the motor, and are used to limit the movement of the motor along the axial direction of the motor shaft, so as to avoid the motor from destroying the connection and cooperation between the motor shaft and the wind wheel due to the movement of the motor along the axial direction of the motor shaft, and ensure the stability of the motor in the air conditioner.

DETAILED DESCRIPTION

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "high", "low", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and a coordinate system XYZ is set herein, wherein the positive direction of the X-axis represents the front, the reverse direction of the X-axis represents the back, the positive direction of the Y-axis represents the right, the reverse direction of the Y-axis represents the left, the positive direction of the Z-axis represents the top, and the reverse direction of the Z-axis represents the bottom; these are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0042] Combination Figure 1 , Figure 2As shown, the present invention provides a motor mounting structure, including a motor bracket 1, a motor gland 2 and a connector 3, wherein the motor bracket 1 and the motor gland 2 are detachably connected via the connector 3, and the motor bracket 1 is suitable for being integrally formed with a mounting plate 4 in an air conditioner.

[0043] The motor mounting structure is applied to the air conditioner. This embodiment and the following text are all explained by taking the motor mounting structure applied to the duct air conditioner (i.e., duct air conditioner) as an example. A detachably connected partition (not shown in the figure) and a mounting plate 4 are provided in the duct air conditioner. The partition divides the internal space of the duct air conditioner into a heat exchange chamber and a fan chamber. The heat exchanger of the duct air conditioner is arranged in the heat exchange chamber, and the motor mounting structure and the mounting plate 4 are located in the fan chamber. The motor mounting structure is connected to the mounting plate 4 so that after the mounting plate 4 is removed from the partition, the motor mounting structure can be removed at the same time, thereby improving the convenience of installation and disassembly of the motor mounting structure. Specifically, one end of the motor bracket 1 of the motor mounting structure is integrally formed with the mounting plate 4, and the other end is detachably connected to the motor gland 2 through a connector 3, and the motor 5 of the duct air conditioner is located between the motor bracket 1 and the motor gland 2. The motor bracket 1 and the motor gland 2 clamp the motor 5 to improve the stability of the motor 5 in the duct air conditioner.

[0044] The motor 5 of the duct air conditioner is used to drive the wind wheel (not shown in the figure) in the volute 8 of the duct air conditioner. In the prior art, the motor bracket 1 and the mounting plate 4 (or partition) are detachably connected by a clamping structure, fasteners (such as screws, bolts, etc.) and other structures. Such a setting easily makes the installation position of the motor bracket 1 on the mounting plate 4 not accurate enough, that is, the position of the motor bracket 1 on the mounting plate 4 is offset, resulting in that after the motor 5 is installed on the motor bracket 1, the axis of the motor shaft 51 (that is, the rotating shaft of the motor 5) of the motor 5 is not in a straight line with the axis of the wind wheel set in the volute 8, thereby increasing the difficulty of assembling the motor 5 and increasing the noise generated when the duct air conditioner is running. The motor bracket 1 in this embodiment is integrally formed with the mounting plate 4. On the one hand, the structural strength of the motor bracket 1 is improved, and the stability of the motor 5 in the duct machine is ensured. On the other hand, the difficulty of disassembly and assembly when the motor bracket 1 and the mounting plate 4 are detachably connected is avoided, and the positioning error of the assembly is avoided. In addition, the loose connection between the motor bracket 1 and the mounting plate 4 due to the detachable connection is avoided during the long-term use of the duct machine, so as to prevent the position of the motor bracket 1 on the mounting plate 4 from being offset and affecting the coaxiality of the motor shaft 51 of the motor 5 and the wind wheel in the volute 8 and increasing the noise generated by the duct machine. It is worth noting that coaxiality refers to the condition that the two axes are kept in the same straight line. The coaxiality in the embodiment of the present invention refers to the condition that the axis of the motor shaft 51 of the motor 5 and the axis of the wind wheel are kept in the same straight line. Therefore, by setting the motor bracket 1 integrally formed with the mounting plate 4, the installation accuracy of the motor 5 on the mounting plate 4 is guaranteed, and the coaxiality of the motor shaft 51 of the motor 5 and the wind wheel is guaranteed.

[0045] Optionally, combined Figure 3-Figure 9 As shown, the connecting member 3 includes a positioning pin 31; the positioning pin 31 is arranged on the motor bracket 1, and the motor cover 2 is provided with a first positioning groove 14, and / or the positioning pin 31 is arranged on the motor cover 2, and the motor bracket 1 is provided with a first positioning groove 14; and the positioning pin 31 is plugged into and matched with the first positioning groove 14.

[0046] In the present embodiment, the detachable connection between the motor bracket 1 and the motor gland 2 is realized by the plug-in fit of the locating pin 31 and the first locating groove 14; the locating pin 31 may be arranged on the motor bracket 1, and the first locating groove 14 may be arranged at a position on the motor gland 2 corresponding to the locating pin 31; the locating pin 31 may also be arranged on the motor gland 2, and the first locating groove 14 may be arranged at a position on the motor bracket 1 corresponding to the locating pin 31; the motor gland 2 and the motor bracket 1 may also be both provided with the locating pin 31 and the first locating groove 14, and the locating pin 31 (first locating groove 14) on the motor gland 2 is plug-in fit with the corresponding first locating groove 14 (locating pin 31) on the motor bracket 1; the locating pin 31 is plug-in fit with the first locating groove 14 to realize the detachable connection between the motor bracket 1 and the motor gland 2, so as to fix the position of the motor 5 in the air duct machine, thereby ensuring the installation accuracy of the motor 5 on the mounting plate 4, and ensuring the coaxiality of the motor shaft 51 of the motor 5 and the wind wheel.

[0047] Optionally, combined Figure 2-Figure 9 As shown, the motor bracket 1 includes a first bracket 11 and a second bracket 12 that are arranged opposite to each other, and a first positioning groove 14 is provided on the side of the first bracket 11 and / or the second bracket 12 facing the motor cover 2, and a positioning pin 31 is provided at a position on the motor cover 2 corresponding to the first positioning groove 14.

[0048] The motor bracket 1 includes a first bracket 11 and a second bracket 12, and the first bracket 11 and the second bracket 12 are respectively arranged on the motor 5 in the length direction of the mounting plate 4 (i.e. Figure 2 The first bracket 11 and the second bracket 12 are arranged at both ends of the motor 5 in the Y-axis direction, so that the connection between the motor gland 2 and the motor bracket 1 is located at both ends of the motor 5 in the length direction of the mounting plate 4. In this way, since the connection between the motor shaft 51 of the motor 5 and the wind wheel of the air duct machine is located at both ends of the motor 5 in the length direction of the mounting plate 4, the stability of the motor 5 when connected to the wind wheel is ensured by arranging the first bracket 11 and the second bracket 12, and the coaxiality of the motor 5 with the wind wheel when the motor 5 is running is ensured.

[0049] Furthermore, since the motor bracket 1 and the mounting plate 4 are integrally formed, and the structure of the locating pin 31 is relatively easy to be damaged relative to the first locating groove 14, the first locating groove 14 is preferably provided on the motor bracket 1, and correspondingly, the locating pin 31 is provided on the motor gland 2, so that the motor gland 2 can be directly replaced after the locating pin 31 is damaged, thereby saving maintenance costs. In the present embodiment, the first locating groove 14 can be provided on the side of the first bracket 11 facing the motor gland 2, or on the side of the second bracket 12 facing the motor gland 2, or on both the side of the first bracket 11 and the second bracket 12 facing the motor gland 2. Accordingly, a locating pin 31 corresponding to the first locating groove 14 is provided on the side of the motor gland 2 facing the motor bracket 1, and the locating pin 31 is plug-fitted with the first locating groove 14.

[0050] Furthermore, the first positioning groove 14 is preferably provided with a plurality of grooves, and is located at the upper ends of the first bracket 11 and the second bracket 12 (i.e., the first bracket 11 is located at the Figure 3 The positive end of the middle Z axis) and the lower end (i.e. the first bracket 11 is located Figure 3 The motor cover 2 and the motor bracket 1 are both provided at the opposite end of the Z axis. Accordingly, a plurality of positioning pins 31 are also provided and are located at the positions of the motor cover 2 corresponding to the first positioning groove 14. In this way, the motor cover 2 and the motor bracket 1 are lifted on the upper side of the motor 5 (that is, the motor 5 is located at Figure 3 The positive side of the Z axis) and the lower side (that is, the motor 5 is located Figure 3 The stability of the connection at the side opposite to the middle Z axis) is ensured to ensure the stability of the motor 5 in the air duct machine and to ensure the coaxiality of the motor shaft 51 of the motor 5 and the wind wheel.

[0051] Optionally, combined Figure 2-Figure 4 , Figure 8 , Fig. 9 As shown, the connecting member 3 also includes a limit buckle 32; the limit buckle 32 is arranged on the motor bracket 1, and a limit groove 15 is provided on the motor cover 2, and / or the limit buckle 32 is arranged on the motor cover 2, and a limit groove 15 is provided on the motor bracket 1; and the limit buckle 32 is engaged with the limit groove 15.

[0052] In this embodiment, the limiting buckle 32 may be arranged on the motor bracket 1, and the limiting groove 15 may be arranged on the motor gland 2; the limiting groove 15 may be arranged on the motor bracket 1, and the limiting buckle 32 may be arranged on the motor gland 2; or the limiting buckle 32 and the limiting groove 15 may be arranged on both the motor bracket 1 and the motor gland 2. The limiting buckle 32 and the limiting groove 15 are engaged with each other to realize the detachable connection between the motor bracket 1 and the motor gland 2, so as to fix the position of the motor 5 in the air duct machine, thereby ensuring the installation accuracy of the motor 5 on the mounting plate 4 and ensuring the coaxiality of the motor shaft 51 of the motor 5 and the wind wheel.

[0053] Based on the detachable connection between the motor bracket 1 and the motor cover 2 through the plug-in cooperation of the positioning pin 31 and the first positioning groove 14, the clamping cooperation of the limit buckle 32 and the limit groove 15 further improves the stability of the connection between the motor bracket 1 and the motor cover 2, and ensures the stability of the motor 5 in the duct machine.

[0054] Optionally, combined Figure 2-Figure 4 , Figure 8 , Fig. 9 As shown, the limiting buckle 32 includes an integrally formed clamping portion 321 and a limiting portion 322 , and a second positioning groove 151 is provided in the limiting groove 15 . When the limiting portion 322 is clamped into the second positioning groove 151 , the clamping portion 321 is clamped with the limiting groove 15 .

[0055] The clamping portion 321 and the limiting portion 322 of the limiting buckle 32 are integrally formed, and the limiting buckle 32 is preferably integrally formed with the motor cover 2 (or the motor bracket 1) to enhance the structural strength of the limiting buckle 32; the clamping portion 321 and the limiting portion 322 are both used to snap into the limiting groove 15 to ensure the stability of the motor bracket 1 when connected to the motor cover 2; and a second positioning groove 151 is provided in the limiting groove 15 for snapping and cooperating with the limiting portion 322 to further enhance the stability of the motor bracket 1 when connected to the motor cover 2.

[0056] Further, for the convenience of description, the following example is taken as follows: the positioning pin 31 and the limiting buckle 32 are arranged on the motor gland 2, and the first positioning groove 14 and the limiting groove 15 are arranged on the motor bracket 1. When the motor gland 2 is installed on the motor bracket 1, the positioning pin 31 is plugged into the first positioning groove 14, and the limiting buckle 32 is snap-fitted into the limiting groove 15, so that the motor bracket 1 plays a role in the upper and lower directions (i.e., Figure 2 Z-axis direction) and left-right direction (i.e. Figure 2 The motor support 1 has a limiting effect on the motor gland 2 in the up-down direction and the left-right direction, which ensures the stability of the motor support 1 and the motor gland 2 when they are connected. The limiting portion 322 of the limiting buckle 32 is engaged with the second positioning groove 151 of the limiting groove 15, so that the motor support 1 passes through the front groove wall of the second positioning groove 151 (that is, the second positioning groove 151 is located at the Figure 8 The groove wall in the positive direction of the middle X axis) and the front side of the limiting portion 322 (that is, the limiting portion 322 is located at Figure 8 The motor support 1 is abutted against the side of the positive X-axis, so that the motor support 1 can prevent the motor gland 2 from moving away from the motor support 1 (i.e. Figure 2 The effect of moving the motor in the positive direction of the X-axis further strengthens the stability of the connection between the motor bracket 1 and the motor gland 2.

[0057] Optionally, combined Figure 2-Figure 4 , Figure 8 , Fig. 9 As shown, the limiting buckle 32 further includes a toggle portion 323 integrally formed with the clamping portion 321 , and the toggle portion 323 extends from one end connected to the clamping portion 321 to the outside of the limiting slot 15 .

[0058] The toggle portion 323 is arranged at the connection between the clamping portion 321 and the limiting portion 322, and the toggle portion 323 is integrally formed with the clamping portion 321 and the limiting portion 322 to ensure the structural strength of the limiting buckle 32, thereby ensuring the stability of the motor bracket 1 and the motor cover 2 when they are connected at the limiting buckle 32; since the limiting buckle 32 has a certain elasticity, and the toggle portion 323 and the clamping portion 321 are U-shaped (or V-shaped structure) as a whole, on the one hand, it is convenient for the limiting buckle 32 to be clamped into the limiting groove 15, and on the other hand, it is easy for the limiting buckle 32 to be elastically deformed when the installer presses the toggle portion 323, thereby facilitating the limiting portion 322 to be clamped into the second positioning groove 151, and facilitating the limiting buckle 32 to be disengaged from the limiting groove 15 to release the clamping connection between the limiting portion 322 and the second positioning groove 151, thereby releasing the clamping connection between the limiting buckle 32 and the limiting groove 15 to disassemble the motor cover 2. In this way, the limiting buckle 32 having the clamping portion 321 , the limiting portion 322 and the pressing portion enhances the stability of the connection between the motor bracket 1 and the motor gland 2 , and improves the convenience of installing and disassembling the motor bracket 1 and the motor gland 2 .

[0059] Furthermore, a guiding slope is provided on the limiting portion 322 to facilitate the limiting buckle 32 to be snapped into the limiting groove 15; for the convenience of description, the limiting buckle 32 is set on the motor cover 2 as an example below, and accordingly, the limiting groove 15 is set on the motor bracket 1, and the limiting portion 322 is set at the end of the clamping portion 321 away from the connection with the motor cover 2, and the guiding slope is set on the side of the limiting portion 322 away from the toggle portion 323, and the included angle between the guiding slope of the limiting portion 322 and the toggle portion 323 is an acute angle. In this way, when the limiting buckle 32 is inserted into the limiting groove 15, the clamping portion 321 enters the limiting groove 15 first, and then the groove wall of the limiting groove 15 away from the connection between the clamping portion 321 and the motor gland 2 abuts against the guiding inclined surface of the limiting portion 322, and the guiding inclined surface of the limiting portion 322 cooperates with the groove wall of the limiting groove 15 away from the connection between the clamping portion 321 and the motor gland 2, so that the limiting buckle 32 slides smoothly into the limiting groove 15; wherein, when the limiting buckle 32 When inserted into the limiting groove 15, the installer can press the toggle portion 323 toward the connection between the clamping portion 321 and the motor cover 2 to make the limiting buckle 32 elastically deform, so as to improve the assembly efficiency of the limiting buckle 32 and the limiting groove 15. After the limiting portion 322 enters the limiting groove 15, the limiting buckle 32 restores its elastic deformation, and the limiting portion 322 is smoothly inserted into the second positioning groove 151, completing the clamping fit between the limiting buckle 32 and the limiting groove 15.

[0060] Optionally, combined Figure 2 , Figure 3 As shown, the motor bracket 1 further includes a connecting plate 13 , and two ends of the connecting plate 13 are respectively integrally formed with the first bracket 11 and the second bracket 12 .

[0061] In order to strengthen the structural strength of the motor bracket 1, the two ends of the connecting plate 13 are respectively formed integrally with the first bracket 11 and the second bracket 12; the connecting plate 13 is arranged at the upper end and / or the lower end of the first bracket 11 and the second bracket 12, and the connecting plate 13 is used to connect the ends of the first bracket 11 and the second bracket 12 located in the same direction. By providing the connecting plate 13, the structural strength of the motor bracket 1 is strengthened, and the stability of the motor bracket 1 when connected to the motor gland 2 is ensured.

[0062] Optionally, combined Figure 3 , Figure 4 , Figure 8 , Fig. 9 As shown, the limiting groove 15 is arranged at an end of the first bracket 11 and / or the second bracket 12 away from the end connected to the connecting plate 13 , and the limiting buckle 32 is arranged at a position on the motor gland 2 corresponding to the limiting groove 15 .

[0063] The connecting plate 13 is preferably arranged at the upper end of the first bracket 11 and the second bracket 12 to avoid the situation that the motor 5 is easily obstructed from being installed on the motor bracket 1 when it is arranged at the lower end of the first bracket 11 and the second bracket 12; accordingly, the limiting groove 15 is arranged at the lower end of the first bracket 11 and / or the second bracket 12, and a limiting buckle 32 is provided at a position corresponding to the limiting groove 15 on the motor gland 2. Compared with the plug-in cooperation of the locating pin 31 and the first locating groove 14, the clamping cooperation of the limiting buckle 32 and the limiting groove 15 is relatively complicated, and when the installer installs or disassembles the motor mounting structure in the air duct machine installed on the ceiling, it is easiest to contact the lower end of the motor mounting structure (that is, the motor mounting structure is located at Figure 8 Therefore, the limit groove 15 is preferably arranged at the lower end of the first bracket 11 and / or the second bracket 12, so that the installer can easily insert the limit buckle 32 into the limit groove 15 or release the clamping fit between the limit buckle 32 and the limit groove 15.

[0064] Optionally, combined Figure 3-Figure 6 As shown, the connecting plate 13 is located above the first bracket 11 and the second bracket 12, and a first limiting surface 131 is provided on the connecting plate 13, and a second limiting surface 21 is provided on the motor cover 2; when the locating pin 31 is plugged into the first locating groove 14, the first limiting surface 131 fits with the second limiting surface 21.

[0065] The connecting plate 13 located above the first bracket 11 and the second bracket 12 is provided with a first limiting surface 131 on one side facing the motor gland 2, and a second limiting surface 21 adapted to the first limiting surface 131 is provided at the upper end of the motor gland 2. When the motor gland 2 is assembled with the motor bracket 1, the first limiting surface 131 abuts and fits with the second limiting surface 21, so that the connecting plate 13 limits the motor gland 2, preventing the motor gland 2 from continuing to move toward the direction of the motor bracket 1 (i.e., Figure 5 The motor cover 2 is moved in the opposite direction of the X-axis to avoid the motor 5 being damaged or being unfavorable to the wiring of the motor 5 due to the motor cover 2 pressing on the motor 5 when the motor cover 2 is installed with the motor bracket 1. Based on the fact that the upper and lower ends of the first bracket 11 and the second bracket 12 are both provided with a first positioning groove 14, and the lower ends of the first bracket 11 and / or the second bracket 12 are provided with a limiting groove 15, the first limiting surface 131 and the second limiting surface 21 are set, so that when the motor cover 2 is installed on the motor bracket 1, the upper end of the motor cover 2 can first cooperate with the motor bracket 1 through the positioning pin 31 and the second limiting surface 21, so as to play a positioning role in the cooperation between the limiting buckle 32 (positioning pin 31) at the lower end of the motor cover 2 and the limiting groove 15 (first positioning groove 14) at the lower end of the motor bracket 1, so as to improve the convenience and accuracy of the assembly of the motor bracket 1 and the motor cover 2.

[0066] Optionally, combined Figure 3 , Figure 4 , Figure 8 , Fig. 9 As shown, a limiting groove 15 is provided on one of the first bracket 11 and the second bracket 12 at one end away from the connection with the connecting plate 13, a threaded hole 16 is provided on the other end of the first bracket 11 and the second bracket 12 at one end away from the connection with the connecting plate 13, and a limiting buckle 32 and a mounting hole 22 are provided on the motor cover 2. The motor bracket 1 and the motor cover 2 are clamped at the limiting groove 15 and the limiting buckle 32, and are suitable for being connected at the threaded hole 16 and the mounting hole 22 by fasteners.

[0067] Based on the limit buckle 32 being arranged at the lower end of the motor bracket 1, the limit groove 15 is arranged on one of the first bracket 11 and the second bracket 12, and the lower end of the other of the first bracket 11 and the second bracket 12 is provided with a threaded hole 16, which is used to cooperate with the mounting hole 22 on the motor gland 2, so that the motor gland 2 and the motor bracket 1 can be detachably connected to the motor gland 2 and the motor bracket 1 by screwing in fasteners (such as screws, etc.) at the mounting hole 22 and the threaded hole 16; similar to the limit buckle 32 being preferably arranged at the lower end of the motor bracket 1, the threaded hole 16 is also preferably arranged at the lower end of the motor bracket 1, so as to facilitate the installer to operate the installation or disassembly of the motor bracket 1 and the motor gland 2 at the lower end of the motor mounting structure. When threaded holes 16 are provided at the lower ends of the first bracket 11 and the second bracket 12, the difficulty of installing or disassembling the motor bracket 1 and the motor cover 2 is increased. When limit buckles 32 are provided at the lower ends of the first bracket 11 and the second bracket 12, the motor bracket 1 and the motor cover 2 are not strong enough. Therefore, the limit groove 15 and the threaded hole 16 are respectively provided on one of the first bracket 11 and the second bracket 12 to ensure the convenience of installing or disassembling the motor bracket 1 and the motor cover 2 and the stability when the motor bracket 1 and the motor cover 2 are connected.

[0068] Furthermore, a screw column is protruding from the lower end of the motor bracket 1, and a threaded hole 16 is arranged in the screw column. In this way, the contact area between the motor bracket 1 and the fasteners screwed into the mounting hole 22 and the threaded hole 16 is increased, thereby improving the stability of the motor bracket 1 when connected to the motor gland 2; and the motor bracket 1 does not need to have a thickness dimension suitable for setting the threaded hole 16 at the threaded hole 16 to ensure the stability of the motor gland 2 when connected to the motor bracket 1, thereby reducing the production cost of the motor bracket 1.

[0069] Optionally, combined Figure 3-Figure 5 , Figure 8 As shown, the motor mounting structure also includes a limiting rib 7; a first opening 61 is provided on the motor bracket 1, and a second opening 62 is provided on the motor cover 2, and the first opening 61 and the second opening 62 constitute a through hole 6 for the motor shaft 51 of the motor 5 to pass through; the limiting rib 7 is arranged at the first opening 61 and / or the second opening 62 to limit the movement of the motor 5 along the axial direction of the motor shaft 51.

[0070] The through hole 6 formed by the first opening 61 and the second opening 62 at the same end of the motor mounting structure is used for the motor shaft 51 of the motor 5 to extend in the left and right directions (i.e. Figure 5The limiting rib 7 is a semicircular prism-shaped structure to match the shape of the first opening 61 or the second opening 62; the limiting rib 7 is convexly arranged on the motor bracket 1 and / or the motor gland 2, and is located at the end of the motor 5, and is used to limit the motor 5 along the axial direction of the motor shaft 51 (i.e. Figure 5 The motor 5 can move in the Y-axis direction to prevent the motor 5 from moving along the axial direction of the motor shaft 51 and thus destroying the connection between the motor shaft 51 and the wind wheel, and ensure the stability of the motor 5 in the air duct machine.

[0071] Furthermore, it is preferred that limiting ribs 7 are provided on both the motor bracket 1 and the motor cover 2 to further strengthen the limiting effect of the motor mounting structure on the motor 5 in the axial direction of the motor shaft 51; specifically, the limiting ribs 7 on the motor cover 2 are provided at both ends of the motor cover 2 in the axial direction of the motor shaft 51, and the limiting ribs 7 on the motor bracket 1 are provided at both ends of the motor bracket 1 in the axial direction of the motor shaft 51, wherein the limiting rib 7 on the first bracket 11 is provided on the side of the first bracket 11 away from the second bracket 12, and the limiting rib 7 on the second bracket 12 is provided on the side of the second bracket 12 away from the first bracket 11, so as to reduce the space occupied by the motor mounting structure in the air duct machine, so as to avoid the limiting rib 7 on the first bracket 11 and the limiting rib 7 on the second bracket 12 being provided too close to each other, so that the motor mounting structure needs to have a larger size in the axial direction of the motor shaft 51 to accommodate the motor 5.

[0072] The present invention also provides an air conditioner, comprising the above-mentioned motor mounting structure.

[0073] The air conditioner of this embodiment is provided with a motor bracket 1 integrally formed with the mounting plate 4. On the one hand, the structural strength of the motor bracket 1 is improved, and the stability of the motor 5 in the air conditioner is ensured. On the other hand, the increased difficulty of disassembly and assembly when the motor bracket 1 is detachably connected to the mounting plate 4 and the occurrence of positioning errors in assembly are avoided. In addition, the loose connection between the motor bracket 1 and the mounting plate 4 due to the detachable connection is avoided during long-term use of the air conditioner, so as to prevent the position of the motor bracket 1 on the mounting plate 4 from being offset, thereby affecting the coaxiality of the motor shaft 51 of the motor 5 and the wind wheel in the volute 8 and increasing the noise generated by the air conditioner. In this way, the installation accuracy of the motor 5 on the mounting plate 4 is ensured, and the coaxiality of the motor shaft 51 of the motor 5 and the wind wheel is ensured.

[0074] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
