Technical Field

[0003] The present application relates to the technical field of air conditioners, and in particular to a mounting bracket assembly and an air conditioner. Background Art

[0004] Prior art split-type air conditioners, designed for easy user installation, use flexible refrigerant piping to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit. Refrigerant is then injected into the refrigerant circuit before the unit leaves the factory. This allows users to install the unit themselves by simply securing the indoor and outdoor units separately, eliminating the need for refrigerant piping or refrigerant filling. This reduces installation complexity and facilitates user-friendly installation.

[0005] The mounting bracket used for installing the air conditioner outdoor unit is usually installed on the window frame at one end, and the other end extends out of the window and is used to support the air conditioner outdoor unit. After the air conditioner outdoor unit is placed on the mounting bracket, it is necessary to use tools such as screwdrivers to lock the screws between the air conditioner outdoor unit and the mounting bracket. This installation method is obviously not convenient enough.

[0085] The present application proposes a mounting bracket assembly for installing an air conditioner outdoor unit. Specifically, the air conditioner of the present application can be a split-type air conditioner that is easy for users to install personally. It uses a flexible refrigerant pipe to connect the indoor heat exchanger of the air conditioner indoor unit and the outdoor heat exchanger of the air conditioner outdoor unit, and injects refrigerant into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the air conditioner indoor unit and the air conditioner outdoor unit separately, without the need to assemble the refrigerant pipe and add refrigerant, thereby reducing the difficulty of installation and enabling personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner of the present application can also be an ordinary split-type air conditioner, or an integrated air conditioner, such as a window-type air conditioner integrated unit. In this case, the air conditioner outdoor unit refers to the part of the window-type air conditioner that extends to the outdoor side.

[0086] The present application proposes a mounting bracket assembly. Referring to Figures 1 to 8 , in one embodiment of the present application, the mounting bracket assembly includes:

[0087] A mounting bracket 101, comprising a main bracket 10, the main bracket 10 comprising a window mounting bracket 11 and a load-bearing bracket 12 connected thereto, the window mounting bracket 11 being mounted on the window frame, the load-bearing bracket 12 extending along a first direction to the outside of the window 103, and the air conditioner outdoor unit 102 being disposed on an upper surface of the load-bearing bracket 12; and

[0088] The first bracket 20 is connected to the air-conditioning outdoor unit 102. One of the load-bearing bracket 12 and the first bracket 20 is provided with a first limiting portion 13 that can be elastically deformed, and the other is provided with a second limiting portion 21. When the air-conditioning outdoor unit 102 moves along the first direction on the load-bearing bracket 12, the first limiting portion 13 can be clamped in the second limiting portion 21.

[0089] Specifically, in the embodiment of the present application, the inner side of the window 103 is defined as the rear, and the outer side of the window 103 is defined as the front. The front-to-back direction is the first direction, the upper side of the air conditioner outdoor unit 102 is the top, and the lower side of the air conditioner outdoor unit 102 is the bottom. In one embodiment, the air conditioner outdoor unit 102 is first placed from top to bottom on the end of the load-bearing bracket 12 near the window, and then pushed forward to a fixed position, that is, pushed away from the window to the fixed position, and then the first stop portion 13 is engaged with the second stop portion 21.

[0090] Of course, in other embodiments, the air-conditioning outdoor unit 102 may be placed from top to bottom on the end of the load-bearing bracket 12 away from the window, and then pulled backward to a fixed position, that is, after being pulled toward the window to a fixed position, the first limiting portion 13 is clamped on the second limiting portion 21.

[0091] In the technical solution of the present application, the air-conditioning outdoor unit 102 is first placed on the load-bearing bracket 12, and then the air-conditioning outdoor unit 102 is pushed or pulled in the first direction so that the first limiting portion 13 can be engaged with the second limiting portion 21, thereby fixing the air-conditioning outdoor unit 102 relative to the load-bearing bracket 12, thus completing the installation and fixation of the air-conditioning outdoor unit 102. In this way, through the structure of the first limiting portion 13 and the second limiting portion 21 cooperating, the air-conditioning outdoor unit 102 can be installed and fixed without the use of screws and corresponding screwdrivers and other tools, making the operation more convenient, thereby improving the user experience.

[0092] Referring to Figures 5 to 8 , in some embodiments, the lower surface of the first bracket 20 is provided with a first through-slot 22 extending in a first direction. When the air conditioner outdoor unit 102 is placed from top to bottom on the load-bearing bracket 12, the first bracket 20 is sleeved onto the upper side of the load-bearing bracket 12 via the first through-slot 22, allowing the load-bearing bracket 12 to move within the first through-slot 22. The second stopper 21 is provided within the first through-slot 22, and the first stopper 13 is provided within the load-bearing bracket 12. In this manner, the first through-slot 22 and the load-bearing bracket 12 cooperate to facilitate smoother movement of the air conditioner outdoor unit 102 within the load-bearing bracket 12 in the first direction, and to enable the first latching protrusion 131 to more smoothly engage with or disengage from the second stopper 21. Of course, in other embodiments, the second stopper 21 may be provided within the load-bearing bracket 12, while the first stopper 13 may be provided within the first through-slot 22. In other embodiments, the first through-slot 22 may not be provided.

[0093] Referring to Figures 5 to 7, in some embodiments, the load-bearing bracket 12 is provided with a first mounting groove 121 and a first through-hole 122 communicating with the first mounting groove 121. The first limiting portion 13 is provided in the first mounting groove 121 and is provided with a first latching protrusion 131 corresponding to the first through-hole 122. The portion of the first latching protrusion 131 extending out of the first through-hole 122 can be latched onto the second limiting portion 21. In this way, the first limiting portion 13 can undergo elastic deformation within the first mounting groove 121, and the first through-hole 122 can limit and guide the first latching protrusion 131, thereby allowing the first latching protrusion 131 to be more smoothly latched onto or disengaged from the second limiting portion 21. Of course, in other embodiments, the first mounting groove 121 and the first through-hole 122 may not be provided, and the first limiting portion 13 may be directly formed on the side wall of the load-bearing bracket 12.

[0094] In some embodiments, the second stopper 21 is disposed on the first sidewall of the first through-slot 22, the notch of the first mounting slot 121 is disposed on the lower surface of the load-bearing bracket 12, and the first through-hole 122 is disposed on the first sidewall of the first mounting slot 121. This allows the lateral space of the load-bearing bracket 12 to be utilized to create space for a user to press the first latching protrusion 131, thereby facilitating the user's manual release of the first latching protrusion 131 from the second stopper 21 and enabling the air conditioner outdoor unit 102 to be removed from the load-bearing bracket 12. Of course, in other embodiments, the second stopper 21 may also be disposed on the bottom wall of the first through-slot 22.

[0095] Referring to Figures 5 to 7 , in some embodiments, a guide portion 23 is further provided on the first sidewall of the first through-slot 22. The second stopper 21 and the guide portion 23 are sequentially arranged along the first direction away from the window mounting bracket 11, and the guide portion 23 extends obliquely away from the load-bearing bracket 12. Specifically, in the present application, when the air conditioner outdoor unit 102 is placed on the load-bearing bracket 12 and pushed backward to secure it, during this pushing process, the first latching protrusion 131 contacts and is acted upon by the guide portion 23, causing the first stopper 13 to elastically deform and automatically retract. Ultimately, the first latching protrusion 131 aligns with the second stopper 21, automatically pops out, and engages with the second stopper 21. In this manner, the guiding action of the guide portion 23 facilitates a smoother engagement of the first latching protrusion 131 with the second stopper 21. Of course, in other embodiments, the guide portion 23 may not be provided. It can be understood that in an embodiment where the air conditioner outdoor unit 102 is placed on the load-bearing bracket 12 and pulled inward to be fixed, the guide portion 23 extends obliquely in a direction close to the window bracket 11 and away from the load-bearing bracket 12.

[0096] It should be noted that in the embodiment of the present application, the relative positional relationship between different components refers by default to the state after the air-conditioning outdoor unit 102 is installed in place on the main bracket 10. Special explanations will be given for special cases.

[0097] Referring to Figure 5 , in some embodiments, the first position-limiting portion 13 includes two first segments 132 and two second segments 133. The two first segments 132 are disposed opposite each other and spaced apart, and are connected by two second segments 133. The two second segments 133 are disposed opposite each other and intersecting. One of the first segments 132 is provided with a first latching protrusion 131 and elastically abuts against one sidewall of the first mounting slot 121, while the other first segment 132 elastically abuts against the other sidewall of the first mounting slot 121. Thus, the first position-limiting portion 13 has a simple structure and is easy to implement. It can stably elastically deform within the first mounting slot 121 to provide a good urging effect on the first latching protrusion 131. Of course, in other embodiments, the first position-limiting portion 13 can also be formed directly on the sidewall of the first mounting slot 121.

[0098] Referring to Figures 5 to 7 , in some embodiments, a mounting hole 123 is defined on the bottom wall of the first mounting slot 121, and a stopper 24 is defined on the first through slot 22 corresponding to the mounting hole 123. The stopper 24 can pass through the mounting hole 123 as the air conditioner outdoor unit 102 is placed, and can move along the first direction with the air conditioner outdoor unit 102, thereby being positionally engaged with the edge of the mounting hole 123. Thus, the interaction between the stopper 24 and the mounting hole 123 allows the load-bearing bracket to further restrict the first bracket, thereby improving the installation reliability of the air conditioner outdoor unit.

[0099] In one embodiment, the mounting through hole 123 includes a communicating clearance hole section 123a and a limiting hole section 123b. The clearance hole section 123a is located on the side of the limiting hole section that is closer to the window mounting bracket 11. The limiting hole section 123b is narrower than the clearance hole section 123a in the slot width direction of the first through slot 22. After passing through the clearance hole section 123a from top to bottom, the stopper 24 can move downwardly away from the window mounting bracket 11 to below the limiting hole section 123b and abut against the lower side of the hole edge of the limiting hole section 123b. This allows for quick and easy vertical positioning of the air conditioner outdoor unit 102, making it easier for users to install and remove the air conditioner outdoor unit 102.

[0100] Referring to Figures 5 to 7 , in one embodiment, the first through-slot 22 includes two opposing first plate segments 224, two second plate segments 225, two opposing third plate segments 226, and a fourth plate segment 227 connecting the two third plate segments 226. The sidewalls of the first through-slot 22 are formed by the first plate segments 224, the third plate segment 226 is disposed opposite the first plate segment 224, and the second plate segment 225 connects the first and third plate segments 224 and 226. The bottom wall of the first through-slot 22 is formed by the second plate segment 225. The third plate segment 226 has a limiting notch 228 at its end away from the window mounting bracket 11, and the stopper 24 is formed at the lower edge of the limiting notch 228. This structure is simple and easy to implement.

[0101] Of course, the stop portion 24 can also have other structural forms. For example, referring to Figures 10 to 12, in another embodiment, the bottom wall of the first through slot 22 is provided with a bent opening 221. The side edge of the bent opening 221, which is adjacent to the window mounting bracket 11, is folded downward to form a first flange 222. The first flange 222 is folded away from the window mounting bracket 11 to form a second flange 223. The stop portion 24 is formed on the second flange 223. This structure is simple and easy to implement.

[0102] It is understood that the second limiting portion 21 can have various structural forms. For example, referring to Figures 6 and 7, the second limiting portion 21 is configured as a limiting hole that adapts to the first latching protrusion 131. In another embodiment, the second limiting portion 21 can also be configured as a limiting notch that adapts to the first latching protrusion 131. Specifically, the contour of the limiting notch is adapted to the first latching protrusion 131. For example, in an embodiment where the first latching protrusion 131 is configured as a cylinder, the limiting notch is configured as a cylindrical surface segment, as shown in Figure 12. Of course, in other embodiments, the straight end surface of the first bracket 20 can also be directly used as the second limiting portion 21, without the need for additional hole structures or notch structures.

[0103] In order to facilitate operation and avoid the risk of slipping when the user pushes and pulls the first bracket 20, the first bracket 20 is provided with an anti-slip portion 229 on the side away from the second limiting portion 21. The anti-slip portion 229 is configured as an anti-slip grille hole or anti-slip grille rib.

[0104] Referring to Figure 7 , in some embodiments, a first bracket 20 is disposed at the end of the load-bearing bracket 12 that is closer to the window mounting bracket 11. The main bracket 10 further includes a position-limiting bracket 14 disposed at the end of the load-bearing bracket 12 that is farther from the window mounting bracket 11 and serves to limit the connection to the air conditioner outdoor unit 102. In this manner, the first bracket 20 and the position-limiting bracket 14 jointly constrain the front and rear ends of the air conditioner outdoor unit 102, further enhancing the installation stability of the air conditioner outdoor unit 102. Of course, in other embodiments, the position-limiting bracket 14 may not be provided.

[0105] 1 and 9 , in some embodiments, the mounting bracket assembly further includes a second bracket 30, which is disposed on the lower surface of the air conditioner outdoor unit 102. When the air conditioner outdoor unit 102 moves along the first direction on the load-bearing bracket 12, the limiting bracket 14 at least partially moves above the second bracket 30 and abuts against the upper surface of the second bracket 30. In this way, the limiting bracket 14 can quickly limit the vertical movement of the air conditioner outdoor unit 102. When installing the air conditioner outdoor unit 102, the user only needs to place the air conditioner outdoor unit 102 on the pre-installed main bracket 10 and then push it forward to a fixed position. No additional operations or auxiliary tools are required.

[0106] Referring to Figures 1 and 13 to 15, in some embodiments, the mounting bracket 101 further includes a support bracket 40 disposed on the load-bearing bracket 12. The support bracket 40 can be adjusted in a first direction along the load-bearing bracket 12 to abut against an exterior wall and / or a window sill. Thus, the mounting position of the support bracket 40 on the main bracket 10 can be adjusted along the first direction, so that the position of the abutting end surface of the support bracket 40 for abutting against the exterior wall and / or window sill relative to the window mounting bracket 11 is adjustable. That is, the spacing between the abutting end surface of the support bracket 40 and the window mounting bracket 11 is adjustable, and this adjustable spacing can accommodate window sills of varying widths. This facilitates user adjustment of the mounting position of the support bracket 40 on the main bracket 10, ensuring that the support bracket 40 abuts against the exterior wall and / or window sill, and enabling the mounting bracket 101 to accommodate varying window sill widths.

[0107] Please refer to Figures 13 to 15. In some embodiments, a first mounting groove 121 is provided on the lower surface of the load-bearing bracket 12, and a plurality of limiting ribs 124 are protruding from the side surface of the first mounting groove 121. The plurality of limiting ribs 124 are spaced apart along the first direction, and a limiting interval 125 is formed between two adjacent limiting ribs 124. A third limiting portion 41 is provided on the upper end of the supporting bracket 40, and the third limiting portion 41 is provided with a second latching protrusion 411 corresponding to the limiting interval 125. The second latching protrusion 411 can be clamped in the limiting interval 125 under the elastic deformation of the third limiting portion 41, and the second latching protrusion 411 can be installed selectively with the plurality of limiting intervals 125.

[0108] In the present application, the limiting gap 125 is formed by the limiting ribs 124 on the inner wall of the first mounting groove 121, and no holes are formed in the sidewalls of the first mounting groove 121. Therefore, the problem of weakening the structural strength of the first mounting groove 121 due to the hole structure is avoided, thereby improving the structural strength of the load-bearing bracket 12 and facilitating the installation reliability of the air conditioner outdoor unit 102. Of course, in other embodiments, the sidewalls or bottom wall of the first mounting groove 121 may also be provided with limiting holes, and the first locking protrusion 131 can be locked in the limiting holes.

[0109] In some embodiments, the load-bearing bracket 12 is integrally stamped to form the limiting rib 124. In this way, the structure is simple and easy to implement, and the manufacturing cost of the load-bearing bracket 12 can be reduced. Of course, in other embodiments, the limiting rib 124 can be set separately from the load-bearing bracket 12, and the limiting rib 124 can be fixed to the load-bearing bracket 12 by welding; the load-bearing bracket 12 can also be machined to form the limiting rib 124 when the first mounting groove 121 is formed, or the load-bearing bracket 12 can be die-cast to form the first mounting groove 121 and the limiting rib 124.

[0110] Referring to Figures 5, 8, 14, and 15, in some embodiments, the main bracket 10 further includes a reinforcing bracket 15, which is disposed on the bottom surface of the first mounting slot 121. This enhances the local structural strength of the load-bearing bracket 12, thereby increasing its service life and improving the installation reliability of the air conditioner outdoor unit 102. Of course, in other embodiments, the reinforcing bracket 15 may not be provided.

[0111] Referring to Figures 5, 14, and 15, in some embodiments, the reinforcing bracket 15 has third flanges 151 folded downward on opposite sides of the reinforcing bracket 15. The upper end of the supporting bracket 40 is provided with a sliding portion 42, the upper end of which slides and abuts between the two third flanges 151. In this way, the reinforcing bracket 15 also serves to limit the left-right movement of the supporting bracket 40. That is, the supporting bracket 40 slides smoothly along the first direction (i.e., the front-to-back direction) on the first mounting slot 121 without any left-right shaking. Of course, in other embodiments, the reinforcing bracket 15 may not have the third flanges 151 and may simply serve to reinforce the load-bearing bracket 12.

[0112] Referring to Figures 5 and 15 , in some embodiments, the reinforcement bracket 15 further includes fourth flanges 152 folded downward on opposite sides thereof. These flanges 152 abut the side surfaces of the first mounting slot 121 and are positioned above the retaining ribs 124. This facilitates positioning the reinforcement bracket 15 within the first mounting slot 121 and provides for a better secure fit between the two. Of course, in other embodiments, the fourth flanges 152 may not be provided.

[0113] Referring to Figures 5 and 15 , in some embodiments, the first mounting slot 121 has fifth flanges 121a folded inward on either side of the slot. The lower end of the sliding portion 42 slides and abuts between the two fifth flanges 121a. A stopper protrudes from the side of the sliding portion 42, which slides and abuts against the inner side of the fifth flange 121a. In this way, the third flange 151 and the fifth flange 121a simultaneously constrain the upper and lower ends of the sliding portion 42, further preventing the risk of the load-bearing bracket 12 from rocking side to side. Of course, in other embodiments, the fifth flange 121a may not be provided.

[0114] Referring to Figures 14 and 15 , in some embodiments, the support bracket 40 further includes a pin 421. The sliding portion 42 is provided with a pin hole corresponding to the pin 421. The portion of the pin 421 extending through the pin hole is configured as a retaining projection. This structure is simple and easy to implement, and facilitates assembly between the support bracket 40 and the load-bearing bracket 12. Of course, in other embodiments, the retaining projection can also be a protruding column welded to the outer surface of the sliding portion 42.

[0115] Referring to Figures 14 and 15 , in some embodiments, the support bracket 40 is provided with a second mounting slot 43 and a second through-hole 44 communicating with the second mounting slot 43 and corresponding to the stop gap 125. The third stopper 41 is disposed in the second mounting slot 43, and the second latching protrusion 411 at least partially extends out of the second through-hole 44. This allows the third stopper 41 to elastically deform smoothly and stably within the second mounting slot 43, while the two through-holes position and guide the second latching protrusion 411, allowing the second latching protrusion 411 to more smoothly engage with or disengage from the stop gap 125. Of course, in other embodiments, the second mounting slot 43 and the second through-hole 44 may not be provided, and the support bracket 40 may directly form the third stopper 41 and the second latching protrusion 411.

[0116] Referring to Figure 14 , in some embodiments, both sides of the first mounting slot 121 are provided with limiting ribs 124, and two second latching protrusions 411 and two second through-holes 44 are provided, with the two second latching protrusions 411 being installed in a one-to-one correspondence with the two sides of the first mounting slot 121. This allows the left and right sides of the support bracket 40 to be subjected to the force exerted by the second mounting slots 43, thereby improving the smoothness of the sliding movement and the installation stability of the support bracket 40. Of course, in other embodiments, limiting ribs and second latching protrusions 411 may be provided on only one side.

[0117] Referring to Figures 14 and 15 , in some embodiments, the bottom wall of the second mounting slot 43 is provided with a folded opening 45. A sixth flange 46 is folded toward the slot of the second mounting slot 43 from the side edge of the folded opening 45 near the load-bearing bracket 12. The sixth flange 46 is folded downward to form a seventh flange 47. The side edge of the folded opening 45, the sixth flange 46, and the seventh flange 47 collectively define an installation space. The third retaining portion 41 includes two intersecting third segments 412. The first ends of the two third segments 412 are connected and positioned within the installation space. The second ends of the third segments 412 are provided with a second latching protrusion 411. In this manner, the sixth flange 46 and the seventh flange 47 can position and restrict the third retaining portion 41, allowing the third retaining portion 41 to be stably installed within the second mounting slot 43 and to deform smoothly within the second mounting slot 43. Of course, in other embodiments, the sixth flange 46 and the seventh flange 47 may not be provided.

[0118] Referring to Figures 16 to 24, in another embodiment of the present application, the mounting bracket assembly includes:

[0119] The mounting bracket 101 includes a main bracket 10, the main bracket 10 includes a window mounting bracket 11 and a load-bearing bracket 12 connected thereto, the window mounting bracket 11 can be mounted on a window frame, the load-bearing bracket 12 extends along a first direction to the outside of the window 103, and the air conditioner outdoor unit 102 is disposed on an upper surface of the load-bearing bracket 12; and

[0120] The first bracket 20 is connected to the air-conditioning outdoor unit 102. One of the load-bearing bracket 12 and the first bracket 20 is provided with a first limiting portion 13 that can be elastically deformed, and the other is provided with a second limiting portion 21. When the air-conditioning outdoor unit 102 moves to the installation position relative to the load-bearing bracket 12, the first limiting portion 13 can be elastically clamped in the second limiting portion 21.

[0121] In the technical solution of the present application, after the air conditioner outdoor unit 102 is mounted on the load-bearing bracket 12 and placed in the installation position, the first limiting portion 13 can be elastically engaged with the second limiting portion 21 and achieve a limiting connection with the second limiting portion 21, thereby limiting the air conditioner outdoor unit 102 in the installation position, thus completing the installation and fixation of the air conditioner outdoor unit 102. In this way, through the structure of the first limiting portion 13 and the second limiting portion 21 cooperating, the air conditioner outdoor unit 102 can be installed and fixed without the use of screws and corresponding screwdrivers and other tools, making the operation more convenient, thereby improving the user experience.

[0122] Please refer to Figures 16 to 32. In some embodiments, optionally, the first limiting portion 13 is provided on the load-bearing bracket 12, and the second limiting portion 21 is provided on the first bracket 20. When the air-conditioning outdoor unit 102 is placed from top to bottom on the load-bearing bracket 12 and is in the installation position, the first bracket 20 can cause the first limiting portion 13 to elastically deform in a direction intersecting the up and down directions so as to be elastically clamped on the second limiting portion 21.

[0123] Specifically, in the embodiment of the present application, the inner side of the window 103 is defined as the rear, and the outer side of the window 103 is the front, then the front-to-back direction is the first direction, the upper side of the air-conditioning outdoor unit 102 is the top, and the lower side of the air-conditioning outdoor unit 102 is the bottom; when facing forward, the left side of the air-conditioning outdoor unit 102 is the left, and the right side of the air-conditioning outdoor unit 102 is the right.

[0124] In the present application, when the air-conditioning outdoor unit 102 is placed from top to bottom on the load-bearing bracket 12, the first bracket 20 extending in the up-down direction can push against the first limiting portion 13, so that the first limiting portion 13 undergoes elastic deformation in a direction intersecting the up-down direction, that is, the first limiting portion 13 undergoes elastic deformation in a substantially horizontal plane. When the first bracket 20 follows the air-conditioning outdoor unit 102 and falls to a preset position (that is, when the air-conditioning outdoor unit 102 is in the installation position), the elastic potential energy of the first limiting portion 13 decreases and is clamped on the second limiting portion 21, thereby completing the restriction of the load-bearing bracket 12 on the first bracket 20. In this way, only this one-step installation operation of placing the air-conditioning outdoor unit from top to bottom is required to complete the installation and fixation of the air-conditioning outdoor unit 102 on the installation bracket 101, making the operation more convenient, thereby further improving the user experience.

[0125] Of course, in other embodiments, the first limiting portion 13 may be provided on the first bracket 20, and the second limiting portion 21 may be provided on the load-bearing bracket 12. At this time, the first limiting portion 13 can follow the air-conditioning outdoor unit 102 to fall to the preset position, and the second limiting portion 21 remains in its original position. In addition, the first limiting portion 13 will be elastically deformed by the stimulation of the first bracket 20 during the falling process, and will eventually be stuck in the second limiting portion 21, thereby completing the restriction of the load-bearing bracket 12 on the first bracket 20.

[0126] It should be noted that the installation method of the air-conditioning outdoor unit 102 is not limited to the above-mentioned direct top-down installation scheme. In other embodiments, the air-conditioning outdoor unit 102 is first placed on the load-bearing bracket 12 from top to bottom, and then the air-conditioning outdoor unit 102 is pushed or pulled to enable it to move along the first direction on the load-bearing bracket 12 and move to the installation position. At this time, the first limit portion 13 elastically deforms and restricts the second limit portion 21. In other words, in this application, a two-step installation operation is required to place the air-conditioning outdoor unit 102 in the installation position.

[0127] Specifically, the air conditioner outdoor unit 102 is first placed from top to bottom on the end of the load-bearing bracket 12 close to the window, and then pushed forward to the installation position. That is, after being pushed in a direction away from the window to the installation position, the first limit portion 13 can be limitedly connected to the second limit portion 21. Alternatively, the air conditioner outdoor unit 102 is first placed from top to bottom on the end of the load-bearing bracket 12 away from the window, and then pulled backward to the installation position. That is, after being pulled in a direction close to the window to the installation position, the first limit portion 13 can be limitedly connected to the second limit portion 21.

[0128] Referring to Figures 20, 26, 29, and 32, in some embodiments, the first bracket 20 includes a latch 25 extending in the vertical direction, with the second stopper 21 disposed on the side of the latch 25. This provides a simple structure and ease of implementation. Of course, in other embodiments, such as those in which the air conditioner outdoor unit 102 is first positioned top-down and then moved in the first direction to the installation position, the first bracket 20 may extend in the front-to-back direction, and the first bracket 20 is not limited to the latch 25 form. For example, the first bracket 20 may be configured as a tubular structure.

[0129] In some embodiments, the lower end surface of the latch 25 is provided with a guide surface 212. The diameter of the axial section of the guide surface 212 is gradually reduced from top to bottom. The second stopper 21 is provided above the guide surface 212. It should be noted that the axial section of the guide surface 212 refers to the cross-section of the guide surface 212 taken perpendicular to the axis of the latch 25. In this way, the guide surface 212 can provide a good guiding function, allowing the latch 25 to more smoothly contact and push against the first stopper 13. Of course, in other embodiments, the guide surface 212 may not be provided, or the guide surface 212 may be provided on the first stopper 13.

[0130] In some embodiments, the second limiting portion 21 is a stop groove provided on the side of the latch 25. Thus, both the upper and lower sides of the stop groove can restrict the first limiting portion 13, thereby improving the connection reliability between the first limiting portion 13 and the first bracket 20. In other embodiments, the second limiting portion 21 can also be a stop step protruding from the side of the first bracket 20, and the first limiting portion 13 can be locked on the upper surface of the stop step.

[0131] Referring to Figures 20, 21, 26, 29, and 32, in some embodiments, the mounting bracket assembly further includes a mounting base 80 disposed on the load-bearing bracket 12. The mounting base 80 includes a conduit portion 81 having a tube lumen 811 for inserting the latch 25 and a clearance opening 812 on the side of the tube lumen 811. The first limiting portion 13 includes a clamping portion 31. The clamping portion 31 can be inserted into the tube lumen 811 through the clearance opening 812 and be clamped on the second limiting portion 21. In this way, the conduit portion 81 can guide and limit the latch 25, facilitating smooth insertion of the latch 25 into the tube lumen 811 and preventing the first bracket 20 from rocking back and forth or left and right on the load-bearing bracket 12. Of course, in other embodiments, the mounting seat 80 may not be provided. For example, the load-bearing bracket 12 is provided with a pin hole corresponding to the latch 25, the first limiting portion 13 is provided on the lower surface of the load-bearing bracket 12, and the portion of the latch 25 passing through the pin hole is provided with a second limiting portion 21.

[0132] Referring to Figures 16, 17, 25, 27, 28, 30, and 31, in some embodiments, in which the air conditioner outdoor unit 102 can be placed from top to bottom on the load-bearing bracket 12 and in the installed position, the mounting bracket assembly further includes a second bracket 72 disposed at an end of the air conditioner outdoor unit 102 distal from the window mounting bracket 11. The second bracket 72 includes a pin extending in the vertical direction, and the main bracket 10 is provided with a pin hole 141 for the pin to be inserted and received. Thus, during the process of the air conditioner outdoor unit 102 being placed from top to bottom on the load-bearing bracket 12, the pin and the pin hole 141 cooperate to provide a guide, allowing the latch 25 to more easily align with the tube lumen 811, thereby facilitating the installation operation. Of course, in other embodiments, the second bracket 72 may not be provided.

[0133] Referring to Figures 16, 17, 25, 27, 28, 30, and 31, in some embodiments, the main bracket 10 further includes a limiting bracket 14. The limiting bracket 14 is disposed at an end of the load-bearing bracket 12 that is distal from the window mounting bracket 11 and at least partially protrudes from the upper surface of the load-bearing bracket 12. In this manner, the portion of the limiting bracket 14 that protrudes from the upper surface of the load-bearing bracket 12 can restrict the front side of the air conditioner outdoor unit 102, preventing the air conditioner outdoor unit 102 from excessively moving forward and falling off the load-bearing bracket 12. Of course, in other embodiments, the limiting bracket 14 may not be provided.

[0134] In some embodiments, two load-bearing brackets 12 and two first position-limiting portions 13 are provided and are installed in a one-to-one correspondence. The two load-bearing brackets 12 are respectively provided at opposite ends of the position-limiting bracket 14, and the pin hole 141 is provided in the middle of the position-limiting bracket 14. The second bracket 72 is protruded from the lower surface of the air-conditioning outdoor unit 102. In this way, the pin hole 141 located on the position-limiting bracket 14 and the two conduit portions 81 located on the load-bearing bracket 12 together form a triangular position, which can better limit the air-conditioning outdoor unit 102, thereby improving the installation reliability of the air-conditioning outdoor unit 102. In other embodiments, the pin hole 141 can also be provided on the load-bearing bracket 12, for example, the pin shaft is provided at the end of the load-bearing bracket 12 away from the window bracket 11, and there are two pin shafts and pin holes 141, and they are provided in a one-to-one correspondence with the two load-bearing brackets 12.

[0135] Please refer to Figures 16 to 21 and Figures 30 to 32. In some embodiments, the first limiting portion 13 also includes a fixing portion 32 connected to the clamping portion 31, and the mounting seat 80 also includes a mounting plate 82 connected to the conduit portion 81. The fixing portion 32 is clamped between the mounting plate 82 and the load-bearing bracket 12. In this way, the fixing portion 32 is pressed against the load-bearing bracket 12 by the mounting plate 82, so that the fixing portion 32 is fixed relative to the load-bearing bracket 12. The structure is simple and easy to implement. Specifically, optionally, the mounting plate 82 is fixed to the load-bearing bracket 12 by screws. Of course, in other embodiments, the mounting plate 82 can also be fixed to the load-bearing bracket 12 by riveting, welding, or bonding.

[0136] Referring to Figures 16 to 21 and 30 to 32, in some embodiments, the lower surface of the mounting plate 82 is provided with a receiving groove 821, and the bottom of the receiving groove 821 is provided with an annular retaining rib 822. The fixing portion 32 is adapted to fit on the outer circumference of the annular retaining rib 822 and is sandwiched between the bottom of the receiving groove 821 and the upper surface of the load-bearing bracket 12. In this manner, the annular retaining rib 822 and the fixing portion 32 cooperate to constrain the fixing portion 32, and the clamping force exerted by the mounting plate 82 and the load-bearing bracket 12 can reliably restrain the fixing portion 32 within the receiving groove 821, thereby facilitating the displacement stability of the clamping portion 31. Of course, in other embodiments, the receiving groove 821 and the annular retaining rib 822 may not be provided, and the fixing portion 32 may be directly secured to the lower surface of the mounting plate 82 by welding, riveting, or bonding, and then the mounting plate 82 is secured to the load-bearing bracket 12.

[0137] It should be noted that the annular structure of the present application, such as the annular retaining rib 822, does not specifically refer to a complete annular structure, but includes an incomplete annular structure, that is, an embodiment in which the annular retaining rib 822 is broken at one point and has two opposing ends, as shown in Figures 6 and 17. For another example, multiple retaining ribs spaced apart along the circumference of the latch 25 together form a substantially complete annular structure.

[0138] Referring to Figures 16 to 20, 25, and 26, in some embodiments, the first bracket 20 further includes a bridging bracket 26, which is disposed on a side of the air conditioner outdoor unit 102 proximate to the window bracket 11, and the latch 25 is disposed on the underside of the bridging bracket 26. This allows the mating structure of the first position-limiting portion 13 and the first bracket 20 to be exposed behind the air conditioner outdoor unit 102, making it easier for the user to observe and operate the first position-limiting portion 13 and providing more operating space, thereby improving the user experience. Of course, in other embodiments, the first bracket 20 may also be disposed on the underside of the air conditioner outdoor unit 102, as shown in the third and fourth embodiments.

[0139] Referring to Figures 17, 19, and 25, in some embodiments, the bridging bracket 26 has a mounting hole 261, the air conditioner outdoor unit 102 has a threaded hole, and the mounting bracket assembly further includes a hand-tightening bolt 71, with the mounting hole 261 being secured to the threaded hole via the hand-tightening bolt 71. This facilitates user installation and disassembly of the bridging bracket 26 and provides an alternative method for installing and disassembling the air conditioner outdoor unit 102, thereby enhancing the flexibility and convenience of installing and disassembling the air conditioner outdoor unit 102. Specifically, in addition to installing or disassembling the bridging bracket 26 and the air conditioner outdoor unit 102 together, the user can also first place the air conditioner outdoor unit 102 separately on the load-bearing bracket 12, then align the latch 25 on the bridging bracket 26 with the conduit portion 81 of the mounting base 80. After the latch 25 is inserted into the conduit portion 81, the mounting hole 261 of the bridging bracket 26 is aligned with the threaded hole, and finally, the mounting hole 261 and the threaded hole are secured together using the hand-tightening bolt 71. Similarly, during the disassembly operation, first release the connection between the hand-tightening bolt 71 and the mounting hole 261 and the threaded hole, then remove the latch 25 and the bridging bracket 26, and finally lift the air conditioner outdoor unit 102 away from the load-bearing bracket 12 alone.

[0140] Referring to Figures 18, 20, and 21, in one embodiment, a first stop protrusion 129 is provided on the upper surface of the mounting plate 82. When the engaging portion 31 is engaged with the second limiting portion 21, the first stop protrusion 129 is located on the side of the engaging portion 31 away from the second limiting portion 21. The first limiting portion 13 is elastically deformable to engage the engaging portion 31 on the side of the first stop protrusion 129 away from the second limiting portion 21. In this manner, the first stop protrusion 129 restrains the engaging portion 31 in a released state, disengaged from the second limiting portion 21, allowing the user to more easily lift the air conditioner outdoor unit 102 off the load-bearing bracket 12 and complete removal of the air conditioner outdoor unit 102. Of course, in other embodiments, the first stop protrusion 129 may not be provided. The user can simultaneously lift the air conditioner outdoor unit 102 while moving the first limiting portion 13 to disengage the engaging portion 31 from the second limiting portion 21, thereby achieving removal of the air conditioner outdoor unit 102.

[0141] Referring to Figures 18, 20, and 21, in one embodiment, the first position-limiting portion 13 further includes an operating portion 33 connected to the fixing portion 32. The operating portion 33 is exposed above the load-bearing bracket 12 and is used to apply an operating force. In this way, the operating portion 33 facilitates the user to manipulate the first position-limiting portion 13 so that the clamping portion 31 is clamped onto the first stop protrusion 129. Specifically, the operating portion 33 optionally includes two intersecting straight rod segments, with the first straight rod segment being disposed opposite the clamping portion 31 and the second straight rod segment connecting the first straight rod segment and the clamping portion 31. Of course, in other embodiments, the operating portion 33 may also be configured as a pull ring, or the operating portion 33 may not be provided.

[0142] Referring to Figures 25 and 26 , in one embodiment, the first position-limiting portion 13 further includes a fixing portion 32 intersecting with the engaging portion 31. The load-bearing bracket 12 is provided with a mounting portion 126 corresponding to the fixing portion 32, and the fixing portion 32 is connected to the mounting portion 126. Thus, the load-bearing bracket 12 is directly provided with the mounting portion 126 for mounting the first position-limiting portion 13, which simplifies the structure of the mounting bracket assembly.

[0143] It should be noted that the first stop protrusion 129 is not limited to being provided on the mounting seat 80, but can also be provided on the load-bearing bracket 12. For example, referring to Figures 25 and 26, in one embodiment, the mounting portion 126 is provided on the upper surface of the load-bearing bracket 12, and the upper surface of the load-bearing bracket 12 is further provided with a first stop protrusion 129. When the clamping portion 31 is clamped on the second limiting portion 21, the first stop protrusion 129 is located on the side of the clamping portion 31 away from the second limiting portion 21; the first limiting portion 13 can be elastically deformed to allow the clamping portion 31 to be clamped on the side of the first stop protrusion 129 away from the second limiting portion 21. In this way, the first stop protrusion 129 can restrain the clamping portion 31 in a released state, away from the second limiting portion 21, so that the user can more easily lift the air conditioner outdoor unit 102 off the load-bearing bracket 12 and complete the disassembly of the air conditioner outdoor unit 102.

[0144] Referring to Figures 25 and 26 , in one embodiment, the upper surface of the load-bearing bracket 12 optionally further comprises a second stopper protrusion 130. The second stopper protrusion 130 is disposed on a side of the clamping portion 31 proximal to the second limiting portion 21, with the clamping portion 31 abutting against the second stopper protrusion 130. In this manner, the second stopper protrusion 130 prevents the clamping portion 31 of the first limiting portion 13 from excessively inserting into the tube lumen 811, thereby facilitating insertion of the latch 25 into the tube lumen 811. Furthermore, the second stopper protrusion 130 may optionally be disposed on an end of the clamping portion 31 proximal to the fixing portion 32, that is, disposed proximal to the rotation axis of the clamping portion 31. Of course, in other embodiments, the second stopper protrusion 130 may not be provided.

[0145] In one embodiment, the mounting portion 126 is located on the side of the engaging portion 31 away from the second retaining protrusion 130 and includes two spaced-apart, opposed mounting ribs with insertion holes into which the fixing portion 32 can be inserted. This provides a simple structure and facilitates the installation and fixation of the fixing portion 32. Of course, in other embodiments, the mounting portion 126 may also adopt other structural forms, such as an annular rib, with the fixing portion 32 adapted to fit over the outer circumference of the annular rib. This is not specifically limited in this application.

[0146] In one embodiment, the load-bearing bracket 12 is integrally formed with the first stop protrusion 129, the second stop protrusion 130, and the mounting rib by stamping. This simplifies the production steps of the structure of the load-bearing bracket 12, thereby reducing the manufacturing cost of the load-bearing bracket 12. Of course, in other embodiments, the first stop protrusion 129, the second stop protrusion 130, and the mounting rib can be provided separately from the load-bearing bracket 12 and fixed to the load-bearing bracket 12 by welding or screwing.

[0147] Referring to Figures 27 to 29, in one embodiment, the second stopper 21 extends along the circumference of the latch 25. The first stopper 13 includes a first rod segment 30a and a second rod segment 30b connected to each other. The first rod segment 30a is sleeved on the circumferential side of the conduit portion 81, and the second rod segment 30b extends into the tube lumen 811 and is configured as the engaging portion 31. Thus, the elastic deformation of the first rod segment 30a on the conduit portion 81 can cause the second rod segment 30b to engage with or disengage from the second stopper 21, resulting in a simple and easy-to-implement structure.

[0148] Referring to Figures 27 to 29 , in one embodiment, the first retaining portion 13 further includes a third segment 30c connected to the second segment 30b. The third segment 30c extends from the second segment 30b in a direction away from the second retaining portion 21 and is at least partially exposed to the side of the load-bearing bracket 12 for manipulation. Thus, the portion of the third segment 30c exposed to the side of the load-bearing bracket 12 allows the user to manipulate it, causing the first segment 30a and the second segment 30b to elastically deform, thereby releasing the second segment 30b from the second retaining portion 21. This provides ample operating space and reduces effort, thereby enhancing the user experience. Of course, in other embodiments, the third segment 30c may not be provided.

[0149] In one embodiment, the central axis of the second rod segment 30b extends along an arc. A disengagement prevention recess 34 is formed on the side of the second rod segment 30b away from the second stopper 21. The mounting base 80 is provided with a disengagement prevention post 825 corresponding to the disengagement prevention recess 34. The disengagement prevention post 825 is located on the side of the disengagement prevention recess 34 away from the second stopper 21. In this manner, the disengagement prevention post 825 prevents the first rod segment 30a from excessively deforming and disengaging from the conduit portion 81, thereby improving the operational stability of the first stopper 13. Of course, in other embodiments, the disengagement prevention post 825 may not be provided, and the central axis of the second rod segment 30b may extend along multiple curved straight lines, or along an S-shaped curve, etc.

[0150] Referring to FIG. 29 , in one embodiment, the mounting base 80 further includes a mounting plate 82 connected to the side of the conduit portion 81 . The circumferential side surface of the conduit portion 81 is provided with at least two anti-slip protrusions 813 . The at least two anti-slip protrusions 813 are spaced apart along the circumference of the conduit portion 81 . The anti-slip protrusions 813 and the lower surface of the mounting plate 82 jointly define an anti-slip groove, and the first rod segment 30a is embedded in the anti-slip groove. In this way, the first rod segment 30a can stably deform on the conduit portion 81 and prevent the first rod segment 30a from detaching from the conduit portion 81 , which would cause the second rod segment 30b to be unable to insert into the tube lumen 811 , thereby improving the reliability of the state switching between the engaging portion 31 and the second limiting portion 21 . Of course, in other embodiments, the anti-slip protrusions 813 may not be provided, and the anti-slip groove may be directly provided on the circumferential side surface of the conduit portion 81 .

[0151] Referring to Figures 28 and 29, in one embodiment, the underside of the load-bearing bracket 12 is provided with a first mounting groove 121. The mounting plate 82 is disposed within the first mounting groove 121. A first through-hole 122 is disposed at the bottom of the first mounting groove 121, and the conduit portion 81 is inserted into the first through-hole 122. A clearance opening 128 is provided on the side of the first mounting groove 121. One end of the third rod segment 30c extends through the clearance opening 128 and is capable of swinging along the extension direction of the clearance opening 128. Thus, the structure of the first mounting groove 121 enhances the structural strength of the load-bearing bracket 12 and conceals the majority of the mounting base 80 and the first stopper 13 within the first mounting groove 121, thereby protecting them and enhancing the neatness and aesthetics of the air conditioner. Of course, in other embodiments, the load-bearing bracket 12 may not have the first mounting groove 121.

[0152] Referring to Figure 29 , in one embodiment, an operating portion 33 is provided at one end of the third rod segment 30c that extends through the clearance opening 128. The operating portion 33 is used to apply an operating force. Thus, the operating portion 33 facilitates the user's ability to move the first limiting portion 13 to disengage the engaging portion 31 from the second limiting portion 21. Specifically, the operating portion 33 may optionally be configured as a pull ring structure. Of course, in other embodiments, the operating portion 33 may comprise two intersecting straight rod segments, with the first straight rod segment positioned opposite the engaging portion 31 and the second straight rod segment connecting the first straight rod segment and the engaging portion 31. Of course, the operating portion 33 may also be omitted.

[0153] Referring to Figures 30 to 32 , in one embodiment, the first limiting portion 13 further includes an operating portion 33 connecting the clamping portion 31 and the fixing portion 32. The load-bearing bracket 12 is provided with a second through-hole 123 corresponding to the operating portion 33. The operating portion 33 passes through the second through-hole 123 and is exposed below the load-bearing bracket 12. The operating portion 33 is driven to deform along the extension direction of the second through-hole 123, thereby causing the clamping portion 31 to engage with or disengage from the second limiting portion 21. In this way, the second through-hole 123 guides and limits the operating portion 33, so that when a user applies an operating force to the operating portion 33, the clamping portion 31 can promptly and effectively disengage from the second limiting portion 21.

[0154] Please refer to Figures 30 to 32. In one embodiment, the bottom of the first mounting groove 121 is provided with a first through hole 122 corresponding to the conduit portion 81, the conduit portion 81 is provided in the first through hole 122, and the clearance opening 812, the clamping portion 31 and the fixing portion 32 are all provided on the upper surface of the load-bearing bracket 12. In this way, it is convenient for the user to observe whether the clamping portion 31 and the second limiting portion 21 are clamped in place. Further optionally, the second through hole 123 is connected to the first through hole 122, so that the load-bearing bracket 12 can be processed into the first through hole 122 and the second through hole 123. Of course, in other embodiments, the first through hole 122 and the second through hole 123 can be separated, or the clearance opening 812, the clamping portion 31 and the fixing portion 32 can be provided on the lower surface of the load-bearing bracket 12.

[0155] Referring to Figures 16, 17, 19, 20, 23 to 25, 27, 28, 30, and 31, in some embodiments, the mounting bracket 101 further includes a support bracket 40 disposed on the load-bearing bracket 12. The support bracket 40 can be adjusted along a first direction on the load-bearing bracket 12 to abut against an exterior wall and / or window sill. Thus, the mounting position of the support bracket 40 on the main bracket 10 can be adjusted along the first direction, such that the position of the abutting end surface of the support bracket 40, which abuts against the exterior wall and / or window sill, relative to the window mounting bracket 11 is adjustable. In other words, the spacing between the abutting end surface of the support bracket 40 and the window mounting bracket 11 is adjustable. This adjustable spacing can accommodate window sills of varying widths. This facilitates user adjustment of the mounting position of the support bracket 40 on the main bracket 10, ensuring that the support bracket 40 abuts against the exterior wall and / or window sill, and allows the mounting bracket 101 to accommodate varying window sill widths. Of course, in other embodiments, the supporting bracket 40 may also be fixed below the load-bearing bracket 12 .

[0156] Referring to Figures 20, 23, 24, and 32, in some embodiments, the lower surface of the load-bearing bracket 12 is provided with a first mounting groove 121, and the main bracket 10 further includes a reinforcing bracket 60 disposed at the bottom surface of the first mounting groove 121. This enhances the local structural strength of the load-bearing bracket 12, thereby increasing its service life and improving the installation reliability of the air conditioner outdoor unit 102. Of course, in other embodiments, the reinforcing bracket 60 may not be provided.

[0157] In some embodiments, the reinforcing bracket 60 has first flanges 61 folded downward on opposite sides thereof. The first flanges 61 are provided with serrations 62 extending in a first direction. When the supporting bracket 40 moves in the first direction, it slides against the serrations 62. In this way, the serrations 62 provide both support and resistance to the supporting bracket 40, allowing the supporting bracket 40 to move in the first direction under a large external force while maintaining a stable position between the load-bearing bracket 12 and the exterior wall.

[0158] Of course, in other embodiments, the mounting bracket 101 may also include an embedded bracket, comprising an embedded portion disposed at the upper end of the support bracket 40. The embedded portion comprises two opposing first plate portions and a second plate portion connecting the two first plate portions, and the embedded portion is adapted to be embedded within the first mounting slot 121. Specifically, the first and second plate portions are provided with an interference fit within the first mounting slot 121, with both the first and second plate portions abutting the inner surface and / or the side edges of the slot of the first mounting slot 121. The static friction generated by the tight fit maintains the upper end of the support bracket 40 relative to the first mounting slot 121. When the position of the support bracket 40 within the first mounting slot 121 needs to be adjusted along the first direction, the support bracket 40 can be tapped with a tool such as a hammer. This simplifies the structure of the mounting bracket 101. Furthermore, the additional embedded bracket increases the contact area between the embedded portion and the first mounting slot 121, thereby increasing the friction between the two and reducing the risk of the support bracket 40 moving along the first direction.

[0159] Please refer to Figures 20, 23 and 23. In one embodiment, the serrated portion 62 is provided on the lower surface of the first flange 61, and the upper end surface of the support bracket 40 abuts the serrated portion 62. In this way, the structure is simple and easy to implement. Further optionally, the notch of the first mounting groove 121 is folded inward with a second flange 127 on both sides, and the opposite sides of the support bracket 40 are protruding with a sliding portion 53 and a limiting protrusion 54. The two sliding portions 53 slide and abut between the two second flanges 127, and the limiting protrusion 54 slides and abuts against the upper side of the second flange 127. In this way, the installation stability of the support bracket 40 on the load-bearing bracket 12 can be improved. Of course, in other embodiments, the second flange 127 may not be provided.

[0160] Please refer to Figure 32. In another embodiment, the first flange 61 is provided with a guide channel 63 extending along the first direction, the lower side of the guide channel 63 is provided with a serrated portion 62, and the outer side surface of the support bracket 40 is provided with a limiting protrusion 54 corresponding to the serrated portion 62. The limiting protrusion 54 is adapted to be installed on the serrated portion 62.

[0161] In another embodiment, second flanges 127 are folded inward on both sides of the first mounting slot 121. The lower side of the first flange 61 abuts the upper side of the second flange 127. Sliding portions 53 and retaining protrusions 54 are protruded from opposite sides of the support bracket 40. The two sliding portions 53 slide and abut between the two first flanges 61. This improves the installation stability of the support bracket 40 on the load-bearing bracket 12. Of course, in other embodiments, the second flange 127 may not be provided.

[0162] Referring to Figures 20, 24, and 32, in some embodiments, a second mounting slot 51 is defined on the side of the support bracket 40 facing the window mounting bracket 11. The support bracket 40 also includes a retaining shaft 52 extending through the two sidewalls of the second mounting slot 51. The portion of the retaining shaft 52 extending beyond the second mounting slot 51 is configured as a retaining protrusion 54. This structure is simple and easy to implement, and facilitates assembly between the support bracket 40 and the load-bearing bracket 12. Of course, in other embodiments, the retaining protrusion 54 may also be a protruding column welded to the outer surface of the sliding portion 53.

[0163] This application also provides an air conditioner comprising an outdoor air conditioner and the aforementioned mounting bracket assembly. The specific structure of the mounting bracket assembly is similar to that of the aforementioned embodiments.
