Description

Technical Field

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

[0002] When installing the motor of an existing duct air supply type air conditioner, two clamps are usually used on each side of the motor to fix it to the motor frame, such as Figure 1 As shown, the first grip A cooperates with the second grip B, and the nut C and the bolt D are used to fix the first grip A and the second grip B, so as to fix the motor. In the installation process, the first grip A and the second grip B need to be hung on the hook of the motor frame first, and then the nut C and the bolt D are fixed. When fixing, the operator needs to align the hole positions of the bolt D and the nut C, and at the same time, prevent the grip A from being separated from the hook at the bottom of the motor bracket, and fix it with a screwdriver with the other hand, which makes the installation operation of this part very inconvenient. Especially in the after-sales installation process, due to the small operating space, the notch of the grip is easy to be separated from the hook of the motor frame, which increases the difficulty of installation and reduces the maintenance efficiency. At the same time, when this installation structure is adopted, the motor is in a cantilever state, and there is no force support at the bottom. During the operation, the motor is unstable and prone to vibration, which further links and causes the vibration of the housing. Summary of the invention

[0003] The problem solved by the invention is to provide a motor mounting structure which can be quickly installed and stably supported.

[0004] In order to solve the above problems, the present invention provides a motor installation structure, comprising:

[0005] A motor frame, the motor frame comprising:

[0006] At least two supporting parts, the at least two supporting parts are respectively fixed relative to the fixing part of the motor to be installed, the supporting parts are provided with a motor fixing position for supporting the fixing part of the motor; the two sides of the motor fixing position on the supporting part are respectively provided with a clamping piece or a notch;

[0007] A holding bracket is provided with a notch corresponding to the clamping piece on the support portion, or a clamping piece corresponding to the notch on the support portion, which is used to cooperate with the motor frame to fix the motor.

[0008] The clamp is installed on the motor frame through the clamps or notches on both sides of the motor fixing position, so that the clamp does not need external force to protect it from falling off during the installation process, which facilitates the installation operation for the installer.

[0009] Furthermore, the clamping member includes:

[0010] A hanging ear is arranged on one side of the motor fixing position;

[0011] A position limiting fixing portion is arranged on the other side of the motor fixing position; the position limiting fixing portion comprises a position limiting flange extending away from the motor;

[0012] A first notch is connected to the hanging ear, and

[0013] The second notch is cooperatively connected with the limiting flange.

[0014] The first notch and the hanging ear, and the second notch and the limiting flange are connected, so that the holding bracket can be conveniently installed on the motor frame. At this time, the holding bracket is hung on the motor and does not need external force to protect it from falling off.

[0015] Furthermore, the free end of the hanging ear extends in a direction away from the fixed position of the motor, so that the hanging ear can be fixed.

[0016] Furthermore, the hanging ear is arranged on a side of the motor fixing position away from the connecting part; the hanging ear is L-shaped, and the first side of the L-shape is connected to the supporting part of the motor frame, and the second side of the L-shape extends in a direction away from the connecting part.

[0017] The L-shaped hook setting of the hanging ear can prevent the hanging device from falling off easily when being installed on the motor.

[0018] Furthermore, a guide portion is provided at an end of the second side of the hook structure away from the motor fixing position, and a width of the guide portion is smaller than a width of the second side close to the motor fixing position.

[0019] By providing the guide portion at the end of the hanging ear structure, it is convenient for the hanging ear to be engaged with the first notch of the holding rack during the holding rack installation.

[0020] Furthermore, the guide portion and a portion of the second side close to the motor fixing position are connected via a bevel.

[0021] In this way, a smooth transition can be achieved between the two parts of the hanging ear with different widths, making the installation process of the hanging ear smoother.

[0022] Furthermore, a slot cooperating with the first notch of the holding bracket can be formed between the first side and the second side of the hanging ear and the supporting portion, and a protrusion is provided on the side of the slot away from the fixed position of the motor.

[0023] Therefore, when the holding bracket is separated from the hanging ear structure, the protrusion can play a certain blocking role, so that the holding bracket will not be easily separated from the hanging ear, further ensuring that the holding bracket does not need to be prevented from falling off by external force during installation.

[0024] Furthermore, the slot on the hanging ear that cooperates with the first notch has a side length C1 along the first side of the hanging ear and a bottom length C2 along the direction of the motor frame support portion, and C2≥C1>C3 is set, wherein C3 is the maximum material thickness at the first notch.

[0025] Therefore, during installation, the holding bracket can be rotated with the contact edge between the first notch and the hanging ear to adjust the installation position and prevent the holding bracket from interfering with the hanging ear; at the same time, C1>C3 is set to ensure that the size of the slot can allow the first notch of the holding bracket to pass smoothly and be engaged.

[0026] Furthermore, a rounded structure is provided at the connection between the first side of the hanging ear close to the motor fixing position and the motor frame support portion, thereby reducing stress concentration.

[0027] Furthermore, the position limiting fixing portion further includes a first fixing plate, and the first fixing plate is located on a side of the supporting portion away from the motor.

[0028] The first fixing plate is provided with a first screw hole for fixing the first fixing plate relative to the clamping plate by means of screws.

[0029] The limiting flange is arranged on the first fixing plate and extends in a direction away from the motor.

[0030] Therefore, the limiting flange can play a positioning role during the climbing installation, thereby improving the installation efficiency.

[0031] Furthermore, the limiting flange is in a T-shape, the lower portion of the T-shape is connected to the first fixing plate, and the upper portion is away from the first fixing plate.

[0032] Therefore, when the limiting flange is installed in cooperation with the second notch, the upper part of the T-shaped limiting flange is wider during the pre-installation of the clamp, which can effectively prevent the limiting flange from being separated from the second notch.

[0033] Furthermore, the width of the lower vertical side of the T-shape is L2, the corresponding second notch length is L1, and the L1-L2 difference △L is set to 3.5-4.5mm.

[0034] In this way, it can be prevented that when the left and right gaps between the limiting flange and the second notch are too large, inaccurate positioning and large deviations in the positions of the upper and lower screw holes make it difficult to fix the screws; and when the gap is too small, the two need to be accurately positioned to be engaged, which increases the difficulty of installation.

[0035] Furthermore, the first notch is stepped, wherein the width of a portion of the first notch away from the motor fixing position is smaller than the width of a portion of the first notch close to the motor fixing position.

[0036] Thus, the shape of the first notch can cooperate with the hanging ear, so that the hanging ear can pass through the wider part of the first notch and be engaged with the narrower part of the first notch when in the installed state, thereby achieving accurate positioning and not being easy to fall off after the pre-installation of the climbing device.

[0037] Furthermore, the width of the first notch away from the motor fixing position is K1, and the width of the first notch close to the motor fixing position is K2, then K1 and K2 satisfy and / or

[0038] If the material thickness of the hanging ear is t, K1 is set to be 0.1-1 mm larger than t.

[0039] In this way, the climbing bracket can be quickly installed on the hanging ear of the motor frame, and the strength of the first notch also meets the use requirements; and by setting the relationship between K1 and t, it is avoided that when the width is too large, the climbing bracket installation displacement is large and the positioning is inaccurate.

[0040] Furthermore, a flange connecting portion is provided on a side of the support portion or the grip away from the motor, and the second notch is provided on the flange connecting portion for allowing the limiting flange to pass through.

[0041] Therefore, when the flange connection part is installed, the bottom edge of the limiting flange can be positioned through the second notch, so that the limiting flange can be pre-positioned during the climbing installation.

[0042] Further, the holding and climbing includes:

[0043] The climbing body comprises an arc segment and a flat plate segment smoothly connected to the first end of the arc segment, the arc segment corresponds to the arc-shaped motor fixing position of the motor frame, and is used to clamp the cylindrical motor fixing part therebetween, and a clamping piece or a notch is provided at the end of the flat plate segment;

[0044] A second fixing plate, wherein the second fixing plate is connected to the second end of the arc segment, and the second fixing plate is provided with the clamping piece or the notch.

[0045] By improving the shape of the grasping bracket body and coordinating the structural settings of the hanging ears and the limiting flanges, the force direction when the grasping bracket is connected to the supporting part is changed, and the horizontal component of the clamping force on the clamping structure of the grasping bracket and the motor frame is increased. At the same time, due to the direction of the limiting flange, the grasping bracket and the motor frame are subjected to clamping forces at multiple angles in the horizontal direction, so that the grasping bracket is not easy to fall off during installation, and the grasping bracket can be easily installed and adjusted.

[0046] Furthermore, a second screw hole is formed on the second fixing plate.

[0047] The first fixing plate and the second fixing plate are fixed relative to each other by screws, so that the connection between the clamp and the motor frame can be tightened.

[0048] Furthermore, the second screw hole on the second fixing plate is provided with threads.

[0049] Therefore, by providing a thread at the second screw hole, for example, a nut is pre-welded at the screw hole of the motor frame, thereby reducing the number of parts that need to be installed during the installation process and improving the installation efficiency.

[0050] Furthermore, an air outlet is provided on the supporting portion of the motor frame.

[0051] Therefore, when the wind wheels on both sides of the motor are running, both sides are in a negative pressure state. The setting of air outlets can increase the wind speed and flow at the bottom of the motor to achieve a cooling effect. At the same time, by setting air outlets, lightweight design requirements can also be met and the weight of the fuselage can be reduced.

[0052] Furthermore, an air outlet skirt is arranged around the air outlet, thereby strengthening the strength of both sides of the motor frame.

[0053] Furthermore, the motor mounting structure further includes:

[0054] A connecting portion is used to connect the motor frame to the volute plate.

[0055] Furthermore, a positioning opening is provided below the connecting portion, and a positioning tongue is provided on one side of the volute plate facing the connecting portion, and the positioning tongue passes through the positioning opening to clamp and position the motor frame.

[0056] The motor frame and the volute plate are clamped and positioned by cooperating with the positioning tongue on the volute plate and the positioning opening provided on the connecting portion, thereby realizing the rapid positioning and installation of the motor frame.

[0057] Furthermore, the support portion of the motor frame is provided with feet for connecting with the top cover plate.

[0058] By setting the foot, the connection between the volute plate and the top cover plate can be further tightened through the connection between the motor frame and the volute plate and the top cover plate, so that the motor runs smoothly and the vibration of the housing is reduced.

[0059] According to another invention of the present invention, there is provided an air conditioner, comprising the motor mounting structure as described above.

[0060] The beneficial effects of the air conditioner are the same as the beneficial effects of the motor mounting structure, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0074] 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.

[0075] In a first exemplary embodiment of the present invention, a motor mounting structure is provided. Figure 2 Schematic diagram of the motor installation structure according to an embodiment of the present invention. Figure 2 As shown, the motor mounting structure of the present invention includes a motor frame 1 and a grip 2, and the motor frame 1 and the grip 2 are connected by screws 4. The motor frame 1 includes two supporting parts 11, and the two supporting parts 11 are respectively arranged on both sides of the motor 3, and the fixing parts on both sides of the motor 3 are fixed by cooperating with a grip 2.

[0076] Specifically, the motor frame 1 is provided with a hanging ear 111 and a position-limiting fixing portion 112 for fixing the holding bracket 2. The correspondingly designed holding bracket 2 is provided with a first notch 21 corresponding to the hanging ear 111 and a second notch 22 matching the position-limiting flange 1122. It is understandable that the positions of the hanging ear 111 and the position-limiting fixing portion 112 can be interchanged. Figure 3a Schematic diagram of the structure of the motor frame of the embodiment of the present invention, as shown in Figure 3a As shown, the two supporting parts 11 of the motor frame 1 are roughly parallel flat plates, and a connecting part 12 is arranged between the two supporting parts 11, and the connecting part 12 is vertically connected to the two supporting parts 11. The two supporting parts 11 are used to be arranged on both sides of the motor 3 to fix the motor 3, and the connecting part 12 is used to fix the motor frame 1 on the volute plate 6. Among them, the hanging ears 111, the limiting flange 1122, the air outlet 113 and the foot 114 are arranged on the supporting part 11 on each side, and the positioning port 121 is arranged below the connecting part 12 of the motor frame 1.

[0077] Please see again Figure 3a The supporting parts 11 on both sides of the motor frame 1 are separated by a predetermined distance, which is determined according to the specific shape and size of the motor 3. An arc-shaped motor fixing position 115 is provided on each side of the supporting part 11, which is used to be arranged below the cylindrical fixing parts protruding on both sides of the motor 3, support the fixing part of the motor 3, and cooperate with the curved holding 2 provided above the fixing part of the motor 3 for fixing.

[0078] Therefore, during the after-sales installation process, the holding bracket 2 can be conveniently hung on the motor frame 1 through the first notch 21 and the hanging ear 111, the second notch 22 and the limiting flange 1122. At this time, the holding bracket 2 is hung on the motor 3, and no external force is required to prevent it from falling off. When fixing the screws, it is only necessary to align the screw holes, so the difficulty of after-sales installation is greatly reduced.

[0079] The motor fixing position 115 of the motor frame 1 is provided with a hanging ear 111 for cooperating with the first notch 21 of the holding bracket 2 on the side away from the connecting portion 12, and a limiting fixing portion 112 for positioning and fixing with the second notch 22 of the holding bracket 2 is provided on the side close to the connecting portion 12. Figure 3b FIG. 1 is an enlarged structural diagram of the motor rack mounting ears according to an embodiment of the present invention. Figure 3bAs shown, the shape of the hanging ear 111 can be designed as a barb type, so as to effectively prevent the hanging ear 111 from easily falling off when it is installed on the motor. Specifically, the hanging ear 111 is generally L-shaped, and its first side 1111 of the L shape is vertically connected to the support portion 11 of the motor frame 1, and the second side 1112 of the L shape extends in a direction away from the motor fixing position 115 of the motor frame 1, so as to achieve stable fixation of the hanging ear 2 and the motor frame 1.

[0080] In this embodiment, the horizontal position of the hanging ear 111 is lower than the horizontal position of the limit fixing portion 112, and the second side 1112 of the L-shape extends downwardly away from the motor fixing position 115 of the motor frame 1. It can be understood that in other embodiments, the horizontal position of the hanging ear 111 can also be higher than the horizontal position of the limit fixing portion, and in this case, the second side 1112 of the L-shape extends upwardly away from the motor fixing position 115 of the motor frame 1.

[0081] Furthermore, a guide portion 1113 is provided at the end of the second side 1112 of the hanging ear 111 structure away from the motor fixing position 115, and the width of the guide portion 1113 is smaller than the width of the second side 1112 close to the motor fixing position 115, so as to facilitate the engagement of the hanging ear 111 with the first notch 21 of the holding bracket 2 when the holding bracket 2 is installed. Preferably, the guide portion 1113 and the part of the second side 1112 close to the motor fixing position 115 are connected by a bevel, so that the two parts of different widths can achieve a smooth transition, making the installation process of the holding bracket smoother.

[0082] In order to fix the holding bracket 2, a slot that matches the first notch 21 of the holding bracket 2 can be formed between the first side 1111, the second side 1112 of the hanging ear 111 and the supporting portion 11 of the motor frame 1. Furthermore, in order to prevent the notch of the holding bracket 2 from easily falling out of the slot, a protrusion 1114 is further provided on the side of the slot away from the motor fixing position 115. Thus, when the holding bracket 2 is separated from the hanging ear 111 structure, the protrusion 1114 can play a certain blocking role, so that the holding bracket 2 will not easily fall off from the hanging ear 111, further ensuring that the holding bracket does not need to be prevented from falling off by external force when it is installed.

[0083] Furthermore, the slot on the hanging ear 111 of the motor frame 1 where it cooperates with the first notch 21 is roughly rectangular, and the side length of the slot along the first side 1111 of the L-shaped hanging ear 111 is C1, and the bottom length along the support portion 11 of the motor frame 1 is C2. During installation, in order to prevent the holding bracket 2 from interfering with the hanging ear 111, the holding bracket 2 is rotated with the contact edge of the first notch 21 and the hanging ear 111 to adjust the installation position, so C2≥C1>C3 is set, where C3 is the external material width of the first notch 21 of the holding bracket 2, that is, the maximum material thickness of the holding bracket at the first notch. By setting C1>C3, it is ensured that the size of the slot can allow the first notch 21 of the holding bracket 2 to pass smoothly and be engaged.

[0084] In addition, in order to reduce stress concentration and increase the stability of the hanging ear 111, a fillet is added to the back of the hanging ear 111, that is, a fillet structure R is set at the connection between the first side 1111 of the hanging ear 111 close to the motor fixing position 115 and the support part 11 of the motor frame 1. The value of R is 2.5-3.5mm. Preferably, R=3mm. When the fillet is too small, the optimization effect of reducing stress concentration is not good. When the fillet is too large, the fillet part will interfere with the grip 2, causing installation abnormality.

[0085] Please see again Figure 3a The limiting fixing part 112 is arranged on the side of the motor fixing position 115 of the motor frame 1 close to the connecting part 12, and includes a first fixing plate 1121 and a limiting flange 1122. The first fixing plate 1121 is perpendicular to the support part 11, and is arranged on the side of the support part away from the motor 3. A first screw hole 1123 is arranged on the first fixing plate 1121 for fixing the clamp 2 relative to the clamp 2 by means of a screw 4. The limiting flange 1122 is arranged on the first fixing plate 1121, and is kept parallel thereto, and further extends in a direction away from the motor 3.

[0086] Figure 3c Schematic diagram of the enlarged structure of the motor frame limit fixing part according to the embodiment of the present invention. Figure 3c As shown, the limiting flange 1122 is arranged on the limiting fixing part 112 of the motor frame 1, and the limiting flange 1122 is in a T-shape, the lower vertical side of the T-shape is connected to the first fixing plate 1121, and the upper horizontal side is away from the first fixing plate 1121, and the second notch 22 of the holding bracket 2 is correspondingly arranged. When the two are installed in coordination, they play a positioning role, and the holding bracket 2 will not fall off when pre-installed, thereby improving the installation efficiency.

[0087] The length of the second notch 22 is L1, the width of the lower vertical side of the T-shaped limiting flange 1122 is L2, and the difference ΔL between L1 and L2 is 3.5-4.5 mm. Preferably, the difference ΔL between L1 and L2 is 4 mm, ensuring that the left and right clearances from the second notch 22 are 2 mm. When the clearance is too large, the positioning is inaccurate, the position deviation of the upper and lower screw holes is large, and the fixing screws are not easy to fix; when the clearance is too small, the two need to be accurately positioned to engage, which increases the difficulty of installation.

[0088] Figure 4a FIG. 1 is a schematic diagram of the structure of the embodiment of the present invention. Figure 4a As shown, the holding bracket 2 includes a holding bracket body 23 and a second fixed plate 25 connected thereto. In this embodiment, the holding bracket body 23 includes an arc segment and a flat plate segment connected to the first end of the arc segment, and the second end of the arc segment is connected to the second fixed plate 25. In this embodiment, the central angle corresponding to the arc segment is less than the predetermined angle, and the flat plate segment is arranged along the tangent direction of the arc segment, wherein the predetermined angle is 150°-180°. By improving the shape of the holding bracket body and coordinating the structural arrangement of the hanging ear and the limiting flange, the force direction when the holding bracket is connected to the support portion is changed, and the clamping force component in the horizontal direction of the clamping structure of the holding bracket and the motor frame is increased. At the same time, due to the direction of the limiting flange, the holding bracket and the motor frame are subjected to the clamping force at multiple angles in the horizontal direction, so that the holding bracket is not easy to fall off during installation, and the installation and adjustment of the holding bracket are convenient.

[0089] Figure 4b This is a schematic diagram of the structure of the connection between the armrest and the motor frame according to an embodiment of the present invention. Figure 4b As shown, the arc section of the main body of the holding rack 2 is opposite to the arc-shaped motor fixing position 115 of the motor frame 1, and is used to clamp the cylindrical motor 3 fixing part between the two. The first notch 21 is set at the end of the flat plate section of the main body of the holding rack 2, which is matched and connected with the hanging ear 111 of the motor frame 1, and the second fixing plate 25 of the holding rack 2 corresponds to the first fixing plate 1121 of the limiting fixing part 112 of the motor frame 1. The second fixing plate 25 is provided with a second screw hole 26, which corresponds to the first screw hole 1123 of the first fixing plate 1121. During installation, the holding rack 2 can be fixed relatively to the motor frame 1 by passing the screws through the screw holes of the first fixing plate 1121 and the second fixing plate 25, and tightening the nuts.

[0090] Furthermore, a flange connecting portion 251 is connected to the side of the second fixing plate 25 away from the motor 3, and the flange connecting portion 251 is perpendicular to the second fixing plate 25, and a second notch 22 is opened on the flange connecting portion 251. When installing, the flange connecting portion 251 can position the bottom edge of the limiting flange 1122, and the second notch 22 is used for the limiting flange 1122 of the power supply frame 1 to pass through for mating connection.

[0091] The first notch 21 on the gripping body 23 is designed to be stepped. The width of the portion away from the motor fixing position 115, i.e., the portion in contact with the hook 111, is K1, and the width of the portion close to the motor fixing position 115 is K2, and K1<K2 is set. Through the step-shaped design of the first notch 21, the hook can pass through the wider portion of the first notch and engage with the narrower portion of the first notch when installed, which facilitates the installation of the hook. Furthermore, it is set Thus, the gripper 2 can be quickly installed on the hanging ear 111 of the motor frame 1, and the strength of the notch also meets the use requirements. The shape of the first notch can match the hook, and the width of the contact part with the hook is set to be narrow, so as to achieve accurate positioning and prevent the clamp from falling off after pre-installation. In addition, if the sheet metal thickness of the motor frame 1 is t, K1 is set to be 0.1-1mm larger than t, so as to avoid large installation displacement of the clamp 2 and inaccurate positioning when the width is too large.

[0092] Furthermore, the edge of the holding bracket body 23 near the motor 3 is provided with a skirt 24, which is used to position the side of the hub of the motor 3. Through the design of the stepped first notch 21, the skirt 24 and the flange connection part 251 of the folded edge, the holding bracket 2 can be quickly installed and positioned, and it is not easy to fall off after pre-installation, and the shaking displacement is small after fixing.

[0093] Preferably, when the first fixing plate 1121 on the motor frame 1 is connected to the second fixing plate 25 on the bracket 2 by screws, nuts can be pre-welded at the screw holes of the motor frame 1, such as Figure 5 As shown, the number of parts to be installed during the installation process is reduced, and the installation efficiency is improved. The spot welding of the nut can be carried out by resistance welding or welding rod welding, and resistance welding is preferably used, which has high welding efficiency and excellent welding quality, appearance and consistency.

[0094] Figure 6a This is a schematic diagram of the structure of the motor before installation according to an embodiment of the present invention; Figure 6b Schematic diagram of the structure of the motor after installation in the embodiment of the present invention. Figure 6a-6b As shown, the motor frame 1 may also be provided with an air vent 113, a foot 114 and a positioning hole 121. The motor 3 will emit a large amount of heat during operation. The air vents 113 are designed on both sides of the motor frame 1. When the wind wheels on both sides of the motor 3 are in operation, the two sides are in a negative pressure state, and the wind speed and flow rate at the bottom of the motor 3 are increased through the air vents 113 to achieve a cooling effect. At the same time, by providing the air vents 113, the lightweight design requirements can also be met and the weight of the fuselage can be reduced. Preferably, an air vent skirt can also be provided around the air vent 113 to strengthen the strength of both sides of the motor frame 1.

[0095] A foot 114 is also provided at the connection between the support portion 11 of the motor frame 1 and the top cover plate 8, which is used to increase the support point and avoid cantilever placement of the motor 3. In this way, the connection between the motor frame 1 and the volute plate 6 and the top cover plate 8 can be further tightened through the connection between the volute plate 6 and the top cover plate 8, so that the motor 3 runs smoothly and the housing vibration is reduced.

[0096] Figure 7 This is a schematic diagram of the volute plate positioning structure of the motor installation structure according to an embodiment of the present invention. Figure 3a and Figure 7 A rectangular opening is provided below the connection portion 12 as a positioning opening 121, which is used to cooperate with the positioning tongue 7 of the volute plate 6, so that the motor frame can be quickly positioned and installed. The volute plate 6 is arranged outside the connection portion 12 of the motor frame 1, and the positioning tongue 7 is fixedly connected to the volute plate 6. The positioning tongue 7 clamps the connection portion 12 upward through the positioning opening 121 below the connection portion 12 of the motor frame 1, thereby further realizing the relative fixation of the motor frame 1 and the volute plate 6.

[0097] In this embodiment, each side of the motor frame 1 is connected with a gripping structure 2, and the nuts are spot welded to the fixing holes of the motor frame 1, so that the number of parts required to be installed on each side of the motor frame 1 is reduced to 2, including a gripping structure 2 and a screw; and after the gripping structure 2 is installed, the screws only need to be aligned with the screw holes to be fixed, so the difficulty of installation is greatly reduced and the efficiency is significantly improved.

[0098] In a second exemplary embodiment of the present invention, an air conditioner is provided, comprising the motor mounting structure as described above.

[0099] 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.
