[0058] This invention proposes a mounting bracket assembly for an indoor unit of an air conditioner. The air conditioner also includes an outdoor unit, and a flexible connection assembly connects the indoor and outdoor units. This air conditioner can be a split-type air conditioner that facilitates individual installation by the user. It uses refrigerant pipes to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when the user installs the equipment themselves, they only need to fix the indoor and outdoor units separately, without needing to assemble the refrigerant pipes or add refrigerant, thereby reducing installation difficulty and enabling individual installation. However, this design is not limited to this. In other embodiments, the air conditioner of this invention can also be a common split-type air conditioner or an integrated air conditioner, such as a window air conditioner unit, in which case the outdoor unit refers to the portion of the window air conditioner that extends to the outside. This mounting bracket assembly can mount the outdoor unit to an external wall or windowsill.

[0059] Furthermore, this type of split-type air conditioner, which is easy for users to install individually, allows the compressor to be placed inside the indoor unit, thereby reducing the weight of the outdoor unit and facilitating its installation on the mounting bracket assembly. Correspondingly, in order to reduce the noise generated by the compressor, a noise reduction structure needs to be installed on the compressor.

[0060] Please see Figures 1 to 3 In one embodiment of this utility model, the mounting bracket assembly includes:

[0061] The main support 1 includes a window mounting bracket 11, a load-bearing bracket 12, and a limiting bracket 13. The window mounting bracket 11 can be installed on the window frame. The load-bearing bracket 12 extends to the outside of the window along a first direction. The limiting bracket 13 is located on the side of the load-bearing bracket 12 away from the window mounting bracket 11. The upper side of the load-bearing bracket 12 is provided with a fixed position for the installation of the outdoor air conditioner unit. The load-bearing bracket 12 and / or the limiting bracket 13 are provided with an auxiliary structure that can assist in limiting the installation of the outdoor air conditioner unit in the fixed position.

[0062] Specifically, the main bracket 1 serves as the structural body of the mounting bracket assembly, providing a place for the outdoor unit of the air conditioner and thus supporting its overall weight. The main bracket 1 includes a window mounting bracket 11, a load-bearing bracket 12, and a limiting bracket 13 arranged sequentially along a first direction. The window mounting bracket 11 can be installed on a window frame, allowing one side of the main bracket 1 to be mounted to the window frame. The load-bearing bracket 12 has a fixed position for installing the outdoor unit; that is, when the outdoor unit is placed in the fixed position, it indicates that the unit is properly installed. Furthermore, the load-bearing bracket 12 and / or the limiting bracket 13 have auxiliary structures that assist in limiting the outdoor unit's installation in the fixed position, thereby improving the stability of the outdoor unit in the fixed position and ensuring the limiting strength; or providing convenience for the outdoor unit's installation in the fixed position, such as providing indicator signs to facilitate user observation of whether the outdoor unit is properly installed, thereby improving the ease of installation and reducing safety hazards.

[0063] In this embodiment, the outdoor unit of the air conditioner can be directly placed in a fixed position, thus directly fixing the outdoor unit in place. This requires a high degree of accuracy in the placement of the outdoor unit. Therefore, in one embodiment, the auxiliary structure includes a first indicator mark 122 located at the fixed position. The first indicator mark 122 indicates that the outdoor unit is installed in the fixed position, further indicating the fixed position of the outdoor unit. When placing the outdoor unit, the user can use the first indicator mark 122 to determine whether the outdoor unit is installed correctly, thereby reducing the risk of inaccurate placement that could lead to the bottom of the outdoor unit not properly matching the load-bearing bracket 12, preventing successful installation.

[0064] In one embodiment, the first indicator mark 122 is configured as a first indicator line, and is positioned flush with the bottom of the outdoor unit of the air conditioner near the window. This allows the structure of the outdoor unit itself to align with the first indicator line, eliminating the need for a corresponding mark on the outdoor unit and simplifying its manufacturing. Alternatively, a corresponding indicator mark can be provided on the outdoor unit to correspond with the second indicator mark 121 for user identification.

[0065] For ease of installation of the outdoor unit of the air conditioner, please refer to the embodiments of this utility model. Figures 2 to 4 , Figure 8 and Figure 9 The load-bearing bracket 12 is also provided with pre-placement positions arranged at intervals from the fixed position along the first direction. The pre-placement positions are used for pre-placing the outdoor unit of the air conditioner. Moving the outdoor unit of the air conditioner along the first direction can fix the outdoor unit of the air conditioner in the fixed position. The auxiliary structure also includes a second indicator mark 121 provided in the pre-placement position. The second indicator mark is used to indicate that the outdoor unit of the air conditioner is placed in the pre-placement position.

[0066] Specifically, in this design, the outdoor unit of the air conditioner is placed on the load-bearing bracket 12 from top to bottom. Then, the outdoor unit is pushed or pulled along a first direction to fix it to the load-bearing bracket 12. Therefore, the load-bearing bracket 12 has pre-placement positions and fixed positions spaced apart along the first direction. The pre-placement positions are for pre-positioning the outdoor unit, thus avoiding direct placement in the fixed positions and providing a certain amount of placement deviation. However, if the user's placement deviation is too large, the bottom of the outdoor unit may not properly match the load-bearing bracket 12, making installation impossible and potentially causing excessive friction and wear on the load-bearing bracket 12. Therefore, the pre-placement positions have a second indicator mark 121, which indicates the pre-placement position of the outdoor unit, making it easier for the user to identify the pre-placement position and facilitating the installation of the outdoor unit.

[0067] In this embodiment, the second indicator mark 121 is configured as a second indicator line. At the pre-placed position, the second indicator line is flush with the bottom of the outdoor air conditioner unit near the window. This allows the outdoor air conditioner unit's structure to align with the indicator line, eliminating the need to add a corresponding mark to the outdoor unit itself, thus facilitating its manufacturing. Alternatively, a corresponding indicator mark can be added to the outdoor air conditioner unit to correspond with the second indicator mark 121 for user identification.

[0068] In this embodiment, the first indicator line is formed by a rib created by a partial recess or protrusion of the load-bearing bracket 12, thereby reducing the possibility of wear on the first indicator line. In other embodiments, the first indicator line may also be a painted line on the load-bearing bracket 12.

[0069] Please see Figures 8 to 12 In an embodiment of this utility model, the mounting bracket assembly further includes a first bracket 14, which is disposed on the lower surface of the outdoor unit of the air conditioner and can slide relative to the load-bearing bracket 12; that is, the first bracket 14 is disposed on the lower surface of the outdoor unit of the air conditioner and is slidably mounted on the load-bearing bracket 12, thereby causing the outdoor unit of the air conditioner to slide on the load-bearing bracket 12.

[0070] In one embodiment, the lower surface of the first bracket 14 is provided with a first through groove 141 extending in a first direction. When the outdoor unit of the air conditioner is placed on the load-bearing bracket 12 from top to bottom, the first bracket 14 is sleeved on the upper side of the load-bearing bracket 12 through the first through groove 141, and the load-bearing bracket 12 can move on the first through groove 141. This provides guidance for the movement of the first bracket 14 on the load-bearing bracket 12, ensures the accuracy of the movement direction, and reduces the possibility of the first bracket 14 detaching from the load-bearing bracket 12.

[0071] Furthermore, the auxiliary structure includes a first limiting part 15 disposed on the load-bearing bracket 12 and a second limiting part 142 disposed on the first bracket 14. The first limiting part 15 is capable of elastic deformation. When the outdoor unit of the air conditioner moves along the first direction on the load-bearing bracket 12 to the fixed position, the first limiting part 15 can be engaged with the second limiting part 142. Specifically, when the first bracket 14 drives the outdoor unit of the air conditioner to move along the first direction on the load-bearing bracket 12 to the fixed position, the first limiting part 15 is engaged with the second limiting part 142, thereby fixing the outdoor unit of the air conditioner and reducing the possibility of the outdoor unit moving in the opposite direction. Moreover, through the structure of the first limiting part 15 and the second limiting part 142 cooperating, the installation and fixing of the outdoor unit of the air conditioner does not require the use of screws and corresponding screwdrivers or other tools, making the operation more convenient and improving the user experience.

[0072] Specifically, see Figure 11 and Figure 12 The load-bearing bracket 12 is provided with a downward-facing mounting groove 123 and a third through hole 124 communicating with the mounting groove 123. The first limiting part 15 includes two pieces 151 and a first locking protrusion 152 provided in one of the two pieces 151. The two pieces 151 are arranged opposite to each other and intersecting. The two opposite sides of the two pieces 151 respectively abut against the two opposite sidewalls of the mounting groove 123. The part of the first locking protrusion 152 extending out of the third through hole 124 can be locked in the second limiting part 142.

[0073] Two pieces 151 are arranged opposite to and intersecting each other, that is, the two pieces 151 are roughly V-shaped. The first locking protrusion 152 is provided on the side of one of the two pieces 151 away from the other, and the opposite sides of the two pieces 151 abut against the two opposite sidewalls of the mounting groove 123. This structure of the first limiting part 15 is simple and easy to implement, and can stably elastically deform within the mounting groove 123 to provide a good actuating effect on the first locking protrusion 152. The first locking protrusion 152 can extend into the third through hole 124, which can limit and guide the first locking protrusion 152, so that the first locking protrusion 152 can be more smoothly locked into or disengaged from the second limiting part 142. Of course, in other embodiments, the first limiting part 15 can also be directly formed on the sidewall of the load-bearing bracket 12.

[0074] Furthermore, since the lower surface of the first bracket 14 is provided with a first through groove 141 extending along the first direction, the second limiting part 142 can be provided at the edge of the groove sidewall of the first through groove 141. A guide plate 143 is also provided on the other side of the groove sidewall. The second limiting part 142 and the guide plate 143 are sequentially distributed along the first direction and away from the window mounting bracket 11, with the guide plate 143 extending obliquely away from the load-bearing bracket 12. Thus, during actual installation, after the outdoor unit of the air conditioner is placed in the preset position on the load-bearing bracket 12 and pushed backward to fix it, the first locking protrusion 152 contacts and is acted upon by the guide plate 143, causing the first limiting part 15 to undergo elastic deformation and automatically retract. Finally, the first locking protrusion 152 aligns with the second limiting part 142 and automatically pops out, locking itself in the second limiting part 142. Thus, through the guiding action of the guide plate 143, the first locking protrusion 152 can be more smoothly locked into the second stopping part. Of course, in other embodiments, the guide plate 143 may not be provided. It can be understood that in an embodiment where the outdoor unit of the air conditioner is placed on the load-bearing bracket 12 and pulled inward to fix it, the guide plate 143 extends obliquely away from the load-bearing bracket 12 in the direction close to the window mounting bracket 11.

[0075] Furthermore, since the first limiting part 15 is elastically engaged in the mounting groove 123 by the two pieces 151 being far apart, the first limiting part 15 may deflect to a certain extent relative to the mounting groove 123 during actual movement. This would cause a certain deflection between the first locking protrusion 152 and the third through hole 124, thus affecting the smoothness of movement of the first locking protrusion 152 relative to the third through hole 124. Therefore, in this embodiment, at least one of the two opposite sidewalls of the mounting groove 123 is provided with a limiting protrusion 125 protruding into the mounting groove 123, and the limiting protrusion 125 abuts against the lower edge of the piece 151. The limiting protrusion 125 abuts against the lower edge of the piece 151, thereby providing a certain blocking effect and ensuring the installation position of the first limiting part 15.

[0076] Alternatively, refer again Figure 11 and Figure 12The auxiliary structure includes a fourth through hole 126 located on the bottom wall of the mounting groove 123 and a stop portion located within the first through groove 141. When the first through groove 141 is fitted onto the load-bearing bracket 12, the stop portion has the fourth through hole 126 inserted into the mounting groove 123, and in the fixed position, the stop portion is engaged with the edge of the fourth through hole 126 for limiting engagement. Specifically, when the outdoor unit of the air conditioner is placed on the load-bearing bracket 12 from top to bottom, the first through groove 141 is fitted onto the load-bearing bracket accordingly. At the same time, the stop portion is inserted into the fourth through hole 126 along with the first through groove 141 and can slide within the fourth through hole 126, thereby further guiding the outdoor unit of the air conditioner to slide in the first direction. When the outdoor unit of the air conditioner slides to the fixed position, the stop portion is engaged with the edge of the fourth through hole 126 for limiting engagement, thereby further limiting the installation of the first bracket 14 and the load-bearing bracket 12, ensuring the installation strength of the first bracket 14 and the load-bearing bracket.

[0077] Furthermore, a limiting notch 1415 is provided on the side of the stop portion away from the window mounting bracket 11. In the fixed position, the edge of the fourth through hole 126 is limited and engaged with the limiting notch 1415. When the first bracket 14 moves forward in the first direction, the lower edge of the limiting notch 1415 can move to the lower side of the hole edge of the fourth through hole 126, thereby achieving a limiting connection between the first bracket 14 and the fourth through hole 126. In this way, the swaying of the first bracket 14 in the vertical direction can be effectively restricted.

[0078] The first through groove 141 includes two opposing first plate segments 1411, two second plate segments 1412, two opposing third plate segments 1413, and a fourth plate segment 1414 connecting the two third plate segments 1413. The sidewall of the first through groove 141 is the first plate segment 1411. The third plate segment 1413 is disposed opposite to the first plate segment 1411. The second plate segment 1412 connects the first plate segment 1411 and the third plate segment 1413. The bottom wall of the first through groove 141 is the second plate segment 1412. The second limiting part 142 is correspondingly disposed on the first plate segment 1411. The two third plate segments 1413 and the fourth plate segment 1414 together form the stopping part. The limiting notch 1415 is correspondingly disposed on the end of the third plate segment 1413 away from the window mounting bracket 11, thereby facilitating the processing and forming of the first bracket 14 and helping to reduce the overall weight of the first bracket 14.

[0079] When the outdoor unit of the air conditioner is placed on the load-bearing bracket 12 from top to bottom, the first through groove 141 is fitted onto the upper side of the load-bearing bracket 12. At the same time, the two third plate segments 1413 and the fourth plate segment 1414 (stop part) are inserted into the fourth through hole 126. The second indicator mark 121 can be set at the edge of the fourth through hole 126 near the window frame, and the corresponding first indicator mark 122 is set at the edge of the fourth through hole 126 away from the window frame. Furthermore, along the arrangement direction from the preset position to the fixed position, the width component of the fourth through hole 126 is reduced, thereby facilitating both the insertion of the first bracket 14 into the load-bearing bracket 12 and the fixing at the fixed position. The lower edge of the limiting notch 1415 can move to the lower side of the hole edge of the fourth through hole 126 for locking, further improving the installation stability of the outdoor unit of the air conditioner.

[0080] Specifically, the fourth through hole 126 includes a clearance hole section and a limiting hole section that are connected. The clearance hole section is located on the side of the limiting hole section near the window mounting bracket 11. The width of the limiting hole section is smaller than the width of the clearance hole section. In the fixed position, the stop part is locked and engaged with the edge of the limiting hole section. The clearance hole section is used for the stop part to be inserted into the mounting groove 123, and the limiting hole section is used to limit the stop part. Therefore, appropriately enlarging the size of the clearance hole section can facilitate the engagement of the first bracket 14 and the load-bearing bracket 12. Appropriately reducing the width of the limiting hole section can further enable the limiting hole section to engage with the stop part, thereby ensuring the stable installation of the outdoor unit of the air conditioner.

[0081] Please see Figure 8 and Figure 9 In an embodiment of this utility model, the mounting bracket assembly further includes a second bracket 16, which is disposed on the lower surface of the outdoor unit of the air conditioner. When the outdoor unit of the air conditioner moves along the first direction on the load-bearing bracket 12, the limiting bracket 13 moves at least partially above the second bracket 16 and abuts against the upper surface of the second bracket 16. In this way, the limiting bracket 13 can quickly restrict the vertical movement of the outdoor unit of the air conditioner.

[0082] Furthermore, the auxiliary bracket includes a guide groove 132 disposed on the limiting bracket 13 and an insertion portion disposed on the second bracket 16. The guide groove 132 extends along a first direction, and when the outdoor unit of the air conditioner moves to a fixed position on the load-bearing bracket 12 along the first direction, the insertion portion of the second bracket 16 can at least partially slide into the guide groove 132. Furthermore, the guide groove 132 is disposed on the lower surface of the limiting bracket 13. When the outdoor unit of the air conditioner moves to the fixed position, the second bracket 16 abuts against the lower part of the limiting bracket 13 and inserts into the guide groove 132. The bottom wall of the guide groove 132 abuts against the second bracket 16 and the outdoor unit of the air conditioner, thereby further limiting the outdoor unit of the air conditioner.

[0083] Furthermore, the width of the guide groove 132 gradually decreases in the direction away from the load-bearing bracket 12. This facilitates the sliding of the limiting bracket 13 into the guide groove 132 and also allows the guide groove 132 to lock the second bracket 16 in the fixed position.

[0084] In one embodiment, the auxiliary structure includes a stop flange 131 disposed on the side of the limiting bracket 13 away from the window frame on the load-bearing bracket 12. The stop flange 131 protrudes from the upper surface of the load-bearing bracket 12, thereby providing a certain blocking effect for the outdoor unit of the air conditioner to prevent the outdoor unit of the air conditioner from extending out of the main bracket 1, and further ensuring the fixed stability of the outdoor unit of the air conditioner when it is installed on the main bracket 1.

[0085] Please see Figures 2 to 7 In an embodiment of this utility model, the lower surface of the load-bearing bracket 12 is provided with an installation groove 123. The installation groove 123 is provided with a plurality of limiting positions distributed at intervals along the first direction. The mounting bracket assembly also includes a support bracket 2 and a limiting member 21 provided at the upper end of the support bracket 2. The upper end of the support bracket 2 extends into the installation groove 123, and the limiting part 211 of the limiting member 21 can be selectively engaged with one of the plurality of limiting positions. The lower end of the support bracket 2 is used to abut against the wall and / or window sill.

[0086] Specifically, the upper end of the support bracket 2 extends into the mounting groove 123 and can slide within the mounting groove 123. Through the interlocking of the limiting part 211 and the limiting slot, the support bracket 2 can be relatively fixed at a certain position on the load-bearing bracket 12. Furthermore, by selectively engaging the limiting part 211 with multiple limiting slots, the relative position of the support bracket 2 on the load-bearing bracket 12 can be adjusted, thus allowing the mounting bracket to adapt to window sills of different widths. Before installing the outdoor unit of the air conditioner, the user needs to first assemble the mounting bracket on the outside of the window. For example, first extend the entire mounting bracket out of the window, then install the window mounting bracket 11 on the window frame, and then adjust the position of the support bracket 2 on the load-bearing bracket 12 so that the lower end of the support bracket 2 can abut against the outer wall surface below the window, and keep the load-bearing bracket 12 in a horizontal or approximately horizontal position, so that the outdoor unit of the air conditioner can be stably placed on the load-bearing bracket 12. Furthermore, the lower end of the support bracket 2 is fixed to the outer wall by pressing, without the need for additional drilling, which facilitates the installation of the support bracket 2 to the outer wall and reduces damage to the wall surface.

[0087] In one embodiment, the limiting member 21 further includes a pushing part 212 connected to the limiting part 211. The pushing part 212 is exposed outside the support bracket 2 and is used for pushing to cause the limiting part 211 to disengage from the limiting position. The user can easily observe and reach the exposed pushing part 212, and can apply force to the pushing part 212, such as by pressing the pushing part 212 directly with a finger, to cause the limiting part 211 to disengage from or engage with the limiting position, and realize the selective installation of the limiting part 211 with multiple limiting positions, thereby improving the convenience of position adjustment of the support bracket 2.

[0088] Furthermore, the support bracket 2 is provided with a first through hole 128, and the limiting position is configured as a second through hole 201 located on the side wall of the mounting groove 123. The pushing part 212 is correspondingly installed in the first through hole 128, and the portion of the pushing part 212 passing through the first through hole 128 is used for pushing. The limiting part 211 is inserted into the second through hole 201 to complete the installation of the upper end of the support bracket 2 and the main bracket 1. Preferably, the second through hole 201 is configured as a circular hole, and the outer peripheral surface of the limiting part 211 is configured as a cylindrical surface adapted to the second positioning hole 172. Of course, in other embodiments, the limiting position may not be a hole structure, for example, it may be a positioning groove, which is formed on the inner side of the mounting groove 123.

[0089] In this embodiment, refer to Figure 8 and Figure 9 The load-bearing bracket 12 includes two parallel load-bearing arms 129 extending along a first direction. The window mounting bracket 11 and the limiting bracket 13 are respectively located at opposite ends of the two load-bearing arms 129 and connect the two load-bearing arms 129, thus making the main bracket 1 as a whole frame-shaped arrangement. Correspondingly, there are also two support brackets 2, which are installed one-to-one with the two load-bearing arms 129. Therefore, each load-bearing arm 129 is provided with multiple limiting slots. To ensure the installation stability of the mounting bracket assembly, the two support brackets 2 should select two parallel limiting slots to engage. However, in actual installation, because there are many limiting slots on the load-bearing arms 129, to install it on the preset limiting slots, the user often needs to count the same number of limiting slots sequentially from one end of the load-bearing arm 129 to determine the position of the display slot, making the installation very inconvenient.

[0090] In view of this, in one embodiment, the load-bearing bracket 12 is further provided with a first indicator mark 1201, which is used to indicate the position of at least part of the limiting position, so that when the user selects the limiting position, there is no need to count from the end, thereby making it easier for the user to quickly locate the position of the limiting position and thus facilitating the user's installation.

[0091] Specifically, the first indicator mark 1201 includes multiple indicator points distributed at intervals along the first direction. The multiple indicator points are all located on one side of the restricted card positions, and the number of restricted card positions between two adjacent indicator points is equal.

[0092] In this embodiment, multiple indicator points are located on one side of the restriction slot, and there are three indicator points between any two adjacent indicator points. This ensures that the number of indicator points is less than the number of restriction slots. During actual installation, the user can locate the restriction slot by counting the number of indicator points. In other embodiments, the third indicator mark 1201 can also be configured as a label located on one side of the restriction slot, that is, the restriction slot is labeled with a corresponding number according to the order of the restriction slots, thereby facilitating the user to quickly locate the position of each restriction slot.

[0093] Furthermore, the indicator point is configured as a recessed portion relative to the load-bearing bracket 12, or a protruding portion relative to the load-bearing bracket 12, thereby facilitating the processing of the indicator point. The indicator point is located at the connection between the bottom wall and the side wall of the mounting groove 123, thus enabling the indicator point to indicate the number of limiting positions while also improving the structural strength of the load-bearing bracket 12 and further facilitating the processing of the indicator point.

[0094] To facilitate the guiding and limiting of the load-bearing bracket 12 within the mounting groove 123, in one embodiment, the mounting groove 123 is provided with a guide groove 1231, and the support bracket 2 is provided with a guide protrusion 202, which can slide within the guide groove 1231. Thus, the guide protrusion 202 and the guide groove 1231 cooperate to guide and position the support bracket 2 as it moves along the first direction, thereby improving the smoothness and stability of the position adjustment operation of the support bracket 2.

[0095] Please see Figure 5 , Figure 6 , Figure 9 and Figure 10 In this embodiment, the groove opening of the mounting groove 123 is bent inward with a second flange 1232, and one sidewall of the guide groove 1231 includes the second flange 1232. The guide protrusion 202 slides against the second flange 1232. Thus, the structure is simple and easy to implement.

[0096] Furthermore, in one embodiment, the main bracket 1 further includes a reinforcing bracket 17 disposed on the bottom wall of the mounting groove 123. The side edge of the reinforcing bracket 17 is bent with a first flange 171. The first flange 171 and the second flange 1232 are spaced apart along the depth direction of the mounting groove 123 and together define the guide groove 1231. Thus, by adding the reinforcing bracket 17 in the mounting groove 123, the structural strength of the mounting bracket in the area of ​​the load-bearing bracket 12 can be improved, so as to be able to withstand a greater weight load, thereby improving the installation reliability of the air conditioner outdoor unit on the load-bearing bracket 12. Moreover, the guide groove 1231 is defined by the first flange 171 of the reinforcing bracket 17 and the second flange 1232 of the mounting groove 123, which simplifies the structure of the load-bearing bracket 12 and facilitates the processing and forming of the load-bearing bracket 12. Of course, in other embodiments, the reinforcing bracket 17 may not be provided, or the guide groove 1231 may be formed by the load-bearing bracket 12.

[0097] In this embodiment, the reinforcing bracket 17 can be fixed to the load-bearing bracket 12 by welding. To ensure precise welding between the two, refer to... Figure 4 and Figure 9 In one embodiment, the load-bearing bracket 12 is provided with a positioning protrusion 1202 protruding into the mounting groove 123, and a corresponding positioning hole 172 is provided on the reinforcing bracket 17. The positioning protrusion 1202 passes through the positioning hole 172, so that during welding, only the corresponding positioning protrusion 1202 and the positioning hole 172 need to be welded. In this example, there are three positioning protrusions 1202, which form a stable triangle, thereby ensuring the welding stability of the reinforcing bracket 17 and the load-bearing bracket 12. In other embodiments, the number of positioning protrusions 1202 can also be multiple.

[0098] In one embodiment, see Figure 9 and Figure 10The support bracket 2 has a first position 1203 on the load-bearing bracket 12. At the first position 1203, the guide protrusion 202 disengages from the guide groove 1231, allowing the support bracket 2 to rotate relative to the load-bearing bracket 12 and enabling the support bracket 2 to have an unfolded state and a retracted state. In the retracted state, the lower end of the support bracket 2 is positioned close to the load-bearing bracket 12. Specifically, when the mounting bracket is shipped from the factory, the support bracket 2 can be pre-installed on the main bracket 1, and the support bracket 2 can be rotated to the retracted state. The lower end of the support bracket 2 and the load-bearing bracket 12 can be fixed together using cable ties, tape, or other means. After the user takes the mounting bracket out of the packaging box, they only need to cut the cable ties or tape, and the lower end of the support bracket 2 will rotate downwards to the unfolded state under its own weight. In this way, the overall size and volume of the mounting bracket can be reduced, which is beneficial for the storage and transportation of the mounting bracket. Furthermore, the user does not need to assemble the mounting bracket themselves; they can use it directly after taking it out of the packaging box, thereby improving the ease of use of the mounting bracket. Of course, in other embodiments, the support bracket 2 may not have the ability to rotate relative to the load-bearing bracket 12.

[0099] Furthermore, at the first position 1203, the sidewall of the mounting groove 123 is also provided with an adjustment hole 1233, so that the limiting part 211 can move within the adjustment hole 1233. Specifically, the adjustment hole 1233 is configured as an oval hole with its length direction being the groove depth direction of the mounting groove 123, and the outer peripheral surface of the limiting part 211 is configured as a cylindrical surface that fits the second positioning hole 172. Thus, when the support bracket 2 is in the retracted state (see...), Figure 7 ) and unfolded state (see Figure 5 When switching, the limiting part 211 can slide within the first positioning hole 172; since the limiting part 211 can extend out of the first positioning hole 172, the limiting member 21 can be kept in a state with low elastic potential energy, which can avoid the problem of the limiting member 21 weakening its elasticity after being subjected to significant compression for a long time.

[0100] Please see Figure 2 , Figure 3 , Figure 5 and Figure 7 In an embodiment of this utility model, the window mounting bracket 11 includes a main body 111 that overlaps the window frame and two folded edges 112 that are bent and connected to the main body 111. The two folded edges 112 are arranged at intervals and are respectively located on the inner and outer sides of the window frame. The two folded edges 112 can be clamped together on the window frame. The window mounting bracket 11 is also provided with an installation through hole 114, through which fasteners can pass and be fastened to the window frame.

[0101] Specifically, the main body 111 is arranged roughly parallel to the load-bearing bracket 12, and the main body 111 overlaps the window frame. Two folded edges 112 are bent and connected to the main body 111, and the two folded edges 112 are arranged at intervals, so that the two folded edges 112 and the main body 111 together form an installation groove 123 to be engaged with the window frame, and the two folded edges 112 can be clamped together with the window frame, thereby engaging the main bracket 1 with the window frame, thus facilitating the installation of the main bracket 1. Furthermore, to facilitate the installation of the window bracket 11 onto the window frame, the distance between the two folded edges 112 is often greater than the thickness of the window frame. Therefore, to ensure that the two folded edges 112 can clamp the window frame, one of the two folded edges 112 is provided with an adjusting member. This adjusting member can adjust the effective clamping distance of the two folded edges 112. In this embodiment, the adjusting member is configured as an adjusting bolt 113 rotatably installed on one of the two folded edges 112. When the two folded edges 112 are located on the inner and outer sides of the window frame, the adjusting nut is tightened so that the adjusting bolt 113 and the other of the two folded edges 112 are clamped together on the window frame. In other embodiments, one of the two folded edges 112 can also be slidably installed on the main body 111 to directly adjust the distance between the two folded edges 112.

[0102] To further ensure the installation stability of the window mounting bracket 11 on the window frame, a mounting through hole 114 is provided on the window mounting bracket 11. Fasteners can pass through the mounting through hole 114 and be securely connected to the window frame, thereby allowing users to further strengthen the connection stability between the window mounting bracket 11 and the window frame according to actual needs. In this embodiment, the mounting through hole 114 is opened in the main body 111, which facilitates the installation of fasteners and ensures the fasteners are securely fixed to the window mounting bracket 11. In other embodiments, the mounting through hole 114 can also be opened in the folded edge 112.

[0103] To ensure the overall strength of the main support bracket 1, in one embodiment, the window mounting bracket 11, the load-bearing bracket 12, and the limiting bracket 13 are integrated. That is, the window mounting bracket 11, the load-bearing bracket 12, and the limiting bracket 13 are assembled into an integrated structure before being used to install the outdoor unit of the air conditioner. When actually installing the outdoor unit of the air conditioner, there is no need to assemble the main support bracket 1, thereby simplifying the installation process of the outdoor unit of the air conditioner, improving the structural strength of the main support bracket 1, and thus ensuring the stability and durability of the mounting bracket and reducing safety hazards.

[0104] In this embodiment, the window mounting bracket 11, the load-bearing bracket 12, and the limiting bracket 13 are integrally formed. Preferably, the window mounting bracket 11, the load-bearing bracket 12, and the limiting bracket 13 are integrally stamped, thereby further improving the structural strength of the main bracket 1 and facilitating the structural strength of the main bracket 1. In other embodiments, the window mounting bracket 11, the load-bearing bracket 12, and the limiting bracket 13 can also be integrally cast.

[0105] In another embodiment, the window mounting bracket 11, the load-bearing bracket 12, and the limiting bracket 13 are welded together as a single unit. That is, the window mounting bracket 11, the load-bearing bracket 12, and the limiting bracket 13 are welded together as a single unit before the mounting bracket assembly leaves the factory. In other embodiments, the window mounting bracket 11, the load-bearing bracket 12, and the limiting bracket 13 can also be connected and fixed into a single structure by fasteners.

[0106] To further ensure the installation strength of the outdoor unit of the air conditioner, in one embodiment, please refer to... Figure 2 and Figure 9 The air conditioner also includes a safety rope. The main bracket 1 has at least two hollow holes 1204, and there is a partition rib between the two hollow holes 1204. One end of the safety rope is connected to the partition rib, and the other end is connected to a fixed position.

[0107] Specifically, one end of the safety rope is securely connected to the main support 1, while the other end is connected to a fixed location, such as a wall, other fixed structure of the building, fixed furniture, or an air conditioner indoor unit. This ensures that even in extreme environments (such as strong winds, heavy rain, or blizzards), the safety rope can tighten the main support 1, reducing the possibility of damage or loosening and providing protection against serious injury or damage caused by the air conditioner outdoor unit falling. The spaced perforations 1204 form dividing ribs, which can be manufactured using a simple stamping process. Optionally, the dividing ribs are arched to facilitate connection of one end of the safety rope. In other embodiments, the safety rope can also be directly bound to the load-bearing arm 129.

[0108] To facilitate the drainage of condensate generated by the indoor unit of the air conditioner, in one embodiment, an indoor drain pipe connects the indoor unit and the outdoor unit, and an outdoor drain pipe connects to the outdoor unit. The indoor drain pipe is used to drain the condensate from the indoor unit into the casing of the outdoor unit, and then drains it out of the air conditioner through the outdoor drain pipe. The outdoor drain pipe is connected to the casing of the outdoor unit and is at least partially located outside the casing. The length and bending shape of the outdoor drain pipe can be arranged according to the actual installation scenario, so that the extension path and bending angle of the outdoor drain pipe can be adjusted. This allows users to arrange the outdoor drain pipe according to their own needs, so as to facilitate the condensate in the air conditioner to be led to the target location.

[0109] To facilitate the fixing of outdoor drainage pipes, in one embodiment, please refer to... Figures 2 to 4 and Figure 8 The main bracket 1 is provided with a limiting slot 127, and the outdoor drain pipe is snapped into the limiting slot 127, which facilitates the fixing of the end of the outdoor drain pipe close to the outdoor unit of the air conditioner, and eliminates the need to set a limiting bracket 13 for limiting, thus simplifying the structure of the mounting bracket assembly.

[0110] This utility model also proposes an air conditioner, which includes an outdoor unit and a mounting bracket assembly. The specific structure of the mounting bracket assembly is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The mounting bracket assembly is used to install the outdoor unit of the air conditioner on the outside of a window.

[0111] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
