     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The technical solutions of the embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. It is obvious that the embodiments to be described are only some rather than all of the embodiments of the present disclosure. All other embodiments obtained by persons skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of the present disclosure. 
     It should be noted that, the descriptions associated with, e.g., “first” and “second,” in the present disclosure are merely for descriptive purposes, and cannot be understood as indicating or suggesting relative importance or impliedly indicating the number of the indicated technical feature. Therefore, the feature associated with “first” or “second” can expressly or impliedly include at least one such feature. 
     Besides, the meaning of “and/or” appearing in the disclosure includes three parallel scenarios. For example, “A and/or B” includes only A, or only B, or both A and B. 
     The present disclosure provides a mounting bracket assembly  100  and a window air conditioner assembly  1000 . As shown in  FIGS. 1 to 8 , the window air conditioner assembly  1000  includes a window air conditioner  200  and a mounting bracket assembly  100 , and the mounting bracket assembly  100  is configured to mount the window air conditioner  200 . 
     As shown in  FIG. 1 , the mounting bracket assembly  100  is mounted at a window of a wall  300  to support and fix an object to the wall  300 . The object may be the window air conditioner  200  or the like, and the window air conditioner  200  will be taken as an example for description below. The window includes a window sill  302 , and a window frame  301  is provided at the window sill  302 . A length direction of the window sill  302  is a width direction of the window, that is, the length direction of the window frame  301 . 
     As shown in  FIGS. 1, 2 and 5 , the mounting bracket assembly  100  includes a support bracket  10 , a connection member  20 , and an outdoor support. 
     As shown in  FIG. 1 , the support bracket  10  is provided at a bottom of the window air conditioner  200 , one end of the support bracket  10  is mounted inside the window frame  301 , and the other end of the support bracket  10  extends outdoors. Specifically, an inner end of the support bracket  10  (the end towards the indoor) is fixedly mounted inside the window frame  301 . An outer end of the support bracket  10  (the end towards the outdoor) extends out of the window, and the window air conditioner  200  is placed at the support bracket  10 . 
     It should be noted that, if there is a directional indication (such as up, down, left, right, front, rear . . . ) in the embodiments of the present disclosure, the directional indication is only used to explain the relative positional relationship and movement between the components in a certain attitude (as shown in  FIGS. 1 and 2 ). If the specific attitude changes, the directional indication changes accordingly. Besides, in the following description, the attitude is generally taken as after the mounting bracket assembly is mounted at the window. 
     Further, as shown in  FIGS. 2, 3, 5 and 7 , the support bracket  10  includes a support plate  11  provided at the bottom of the window air conditioner  200 . One end of the support plate  11  is provided at the window sill  302 , and the other end is used to extend out of the window. In this embodiment, as shown in  FIGS. 2, 3, 5 and 7 , the support plate  11  extends in the length direction of the window air conditioner  200 . For other window air conditioners  200  (such as a rectangular window air conditioner  200  and the like), the support plate  11  does not necessarily extend along the length direction of the window air conditioner  200 . So, in other words, the support plate  11  extends in a direction from an outdoor side of the window air conditioner  200  towards an indoor side of the window air conditioner  200 . 
     Specially, as shown in  FIGS. 2, 3, 5 and 7 , the support plate  11  includes an inner support portion  111 , an outer support portion  113 , and an intermediate connection portion  112 . The inner support portion  111  is provided above the window sill  302 , the outer support portion  113  extends outside, and the outer support portion  113  is lower than the inner support portion  111 . The intermediate connection portion  112  is connected to the inner support portion  111  and the outer support portion  113 . Specially, the intermediate connection portion  112  is inclined. The inner support portion  111  is connected to one end (that is, the inner end) of the intermediate connection portion  112  and extends indoors. The outer support portion  113  is connected to the other end (that is, the outer end) of the intermediate connection portion  112  and extends outdoors. In this embodiment, as shown in  FIGS. 2, 3, 5 and 7 , the inner support portion  111  and the outer support portion  113  are both horizontal. The outer support portion  113  is located below the inner support portion  111 , and the intermediate connection portion  112  is inclined to connect the inner support portion  111  and the outer support portion  113 . 
     In this embodiment, as shown in  FIG. 1 , the window air conditioner  200  has a division groove  201 . The division groove  201  divides the window air conditioner  200  into an indoor portion  200   a  and an outdoor portion  200   b . The division groove  201  is provided above the inner support portion  111 , an outer end of the outdoor portion  200   b  is provided at the outer support portion  113 , an inner end of the outdoor portion  200   b  is optionally provided at the inner support portion  111 . The division groove  201  is configured for the shield member provided at the window to extend into. 
     Specially, the window air conditioner  200  includes a housing (not shown), and a compressor, an outdoor heat exchanger, an outdoor fan, an indoor heat exchanger and an indoor fan (not shown) provided in the housing. The division groove  201  is provided at the housing. The compressor, the outdoor heat exchanger, and the outdoor fan are provided at the outdoor portion  200   b . The indoor heat exchanger and the indoor fan are mounted in the indoor portion  200   a.    
     Further, as shown in  FIGS. 3, 5, 7 and 8 , the support bracket  10  further includes a lateral fixation member  1 . The lateral fixation member  1  extends along the length direction of the window sill  302 . The lateral fixation member  1  is fixed to the inner side of the window frame  301  (that is, the side of the window frame  301  towards the indoor). The inner end of the support plate  11  is connected to the lateral fixation member  1  to fix the support plate  11 . Specially, the inner end of the inner support portion  111  is connected to the lateral fixation member  1 , and the bottom of the inner support portion  111  abuts the upper portion of the window frame  301 . Optionally, the lateral fixation member  1  has an abutting surface that abuts the inner side surface of the window frame  301 . 
     The lateral fixation member  1  is fixed to the inner side of the window frame  301 . When the window air conditioner  200  is placed at the support bracket  10 , the gravity of the outdoor portion  200   b  of the window air conditioner  200  is transmitted to the lateral fixation member  1  through the support plate  11 . The lateral fixation member  1  abuts the inner side of the window frame  301  to support the window air conditioner  200  to prevent the window air conditioner  200  from turning to the outside, thereby improving the mounting stability of the window air conditioner  200 . Besides, the lateral fixation member  1  and the support plate  11  may also form a stepped structure to rapidly position the support bracket  10 . 
     Specially, the lateral fixation member  1  is provided below the indoor portion  200   a  of the window air conditioner  200 . 
     In some embodiments, the inner end of the inner support portion  111  is connected to the lateral fixation member  1  through a screw lock structure. 
     In a specific embodiment, there are many structural forms of the lateral fixation member  1 , such as a block, a plate, or a tube. The lateral fixation member  1  may be an integrally formed component or an assembly. The following uses the lateral fixation member  1  being an assembly as an example for description. 
     Further, as shown in  FIGS. 3, 5, 7 and 8 , the lateral fixation member  1  includes a lateral limiting member  12 . The lateral limiting member  12  extends along the length of the window sill  302 . The lateral limiting member  12  is used to abut against the inner side of the window frame  301 . The inner end of the support plate  11  is connected to the lateral limiting member  12  to fix the support plate  11 . 
     In some embodiments, the length of the lateral limiting member  12  is equivalent to the width of the window air conditioner  200  (that is, the length in the length direction of the window sill  302 ). That is to say, the length of the lateral limiting member  12  may be slightly larger than the width of the window air conditioner  200 , may also be equal to the width of the window air conditioner  200 , or may be slightly smaller than the width of the window air conditioner  200 . 
     Further, as shown in  FIGS. 3, 5, 7 and 8 , the lateral fixation member  1  further includes two lateral extension members  13  provided at two ends of the lateral limiting member  12 . The lateral extension member  13  extends along the length of the window sill  302 . The end of the lateral extension member  13  away from the lateral limiting member  12  is used to connect with the side wall of the window to fix the lateral limiting member  12  and the lateral fixation member  1  to the inner side of the window frame  301 . In this way, the mounting stability of the support bracket  10  can be guaranteed/improved. 
     Further, as shown in  FIGS. 3, 5, 7 and 8 , the lateral extension member  13  and the lateral limiting member  12  are movably engaged in the length direction of the window sill  302 , so that the length of the lateral fixation member  1  in the length direction of the window sill  302  is adjustable. In this way, the support bracket  10  can be adapted to windows of different widths, the scope of application of the support bracket  10  and the mounting bracket assembly  100  is expanded, and the versatility of the support bracket  10  and the mounting bracket assembly  100  is improved. 
     Further, the lateral limiting member  12  is provided with first mounting positions spaced apart from each other in the length direction of the window sill  302 . The lateral extension member  13  is provided with second mounting positions matching the first mounting positions. In this way, a reliable cooperation between the lateral limiting member  12  and the lateral extension member  13  can be ensured. It can be understood that the second mounting position can be selectively connected with one of the first mounting positions, so that the length of the lateral fixation member  1  in the length direction of the window sill  302  can be adjusted. 
     In this embodiment, as shown in  FIG. 8 , the lateral limiting member  12  is tubular, and the lateral extension member  13  is slidably arranged at the lateral limiting member  12 . 
     Further, as shown in  FIG. 8 , the lateral limiting member  12  includes a limiting top plate  121 , a first limiting side plate  122 , a second limiting side plate  123  and two limiting bottom plates  124 . 
     As shown in  FIGS. 5 and 8 , the limiting top plate  121  is disposed upward. 
     As shown in  FIG. 8 , the first limiting side plate  122  and the second limiting side plate  123  are disposed at opposite sides of the limiting top plate  121 , respectively. Optionally, the first mounting position may be set on the first limiting side plate  122  or the second limiting side plate  123 . 
     As shown in  FIG. 8 , two limiting bottom plates  124  are disposed at two ends of the first limiting side plate  122 , respectively, and the limiting bottom plate  124  is opposite to the limiting top plate  121 . 
     A mounting space is enclosed between the limiting top plate  121 , the first limiting side plate  122 , the second limiting side plate  123 , and the limiting bottom plate  124 . A first opening  125  communicating with the mounting space is formed between the two limiting bottom plates  124 . 
     Further, as shown in  FIG. 8 , a length of the first limiting side plate  122  is greater than a length of the second limiting side plate  123 , and two excess portions are formed at two ends of the first limiting side plate  122 . The excess portion protrudes from the first limiting side plate  122  in the length direction of the window sill  302 . Optionally, the limiting bottom plate  124  is provided at the excess portion. 
     The limiting bottom plate  124  and the limiting top plate  121  form a second opening  126  communicating with the mounting space on the side where the second limiting side plate  123  is located. 
     The lateral limiting member  12  may be a stamping member. 
     As shown in  FIGS. 5, 6 and 8 , the lateral extension member  13  includes an extension bottom plate  131 , a first extension side plate  132  and a second extension side plate  133 . The first extension side plate  132  and the second extension side plate  133  are disposed at opposite sides of the extension bottom plate  131 , respectively. An upper opening is formed on the upper edge of the first extension side plate  132  and the second extension side plate  133 . 
     The lateral extension member  13  is slidably mounted in the mounting space, and the extension bottom plate  131  is opposite to the limiting top plate  121 . The first extension side plate  132  is adjacent to the first limiting side plate  122 , and the second extension side plate  133  is adjacent to the second limiting side plate  123 . 
     As such, a first opening  125  and a second opening  126  are formed on the lateral limiting member  12 . When the lateral limiting member  12  is produced by stamping, it is easy to design and produce molds, thereby it is easy to reduce the production difficulty of the lateral limiting member  12 , realizing mass production, reducing production costs, and saving materials. The structural strength of the lateral limiting member  12  can also be ensured to ensure/improve the supporting effect of the window air conditioner  200 . 
     Meanwhile, forming the second opening  126  on the lateral limiting member  12  can facilitate guiding the lateral extension member  13  into the mounting space. Forming the first opening  125  and the second opening  126  on the lateral limiting member r  12  can reduce the friction between the lateral extension member  13  and the lateral limiting member  12  so that the lateral extension member  13  slides in the mounting space. 
     Besides, through the above arrangement, the structure of the lateral extension member  13  can also be simplified, and by placing the extension bottom plate  131  and the limiting top plate  121  oppositely, the connection strength of the lateral limiting member  12  and the lateral extension member  13  can also be improved. 
     Further, as shown in  FIG. 8 , the limiting bottom plate  124  and the second limiting side plate  123  are spaced apart from each other in the length direction of the window sill  302  (that is, the length direction of the lateral limiting member  12 ), to form a third opening  127  communicating with the mounting space between the second limiting side plate  123  and the second opening  126 . In this way, the friction between the lateral extension member  13  and the lateral limiting member  12  can be reduced to facilitate the insertion of the lateral extension member  13  into the mounting space. 
     In addition, by providing the first opening  125 , the second opening  126 , and the third opening  127 , it is convenient to realize mold opening to achieve mass production. 
     Further, the lateral limiting member  12  is an integrated bending structure. 
     Further, as shown in  FIG. 8 , the first mounting position is a first connection hole  1221  provided at the first limiting side plate  122  and penetrating through the first limiting side plate  122 . A plurality of first connection holes  1221  are spaced apart from each other in the length direction of the window sill  302 . The second mounting position is a second connection hole (not shown) provided at the first extension side plate  132  and penetrating through the first extension side plate  132 . 
     Fasteners (such as screws or pins) pass through the first connection hole  1221  and the second connection hole to connect the first limiting side plate  122  and the first extension side plate  132 , to ensure the stability of the length of the lateral fixation member  1 , thereby ensuring the reliability of the support bracket  10 . 
     In some embodiment, the first limiting side plate  122  faces the indoor direction. The second limiting side plate  123  is configured to abut the inner side surface of the window frame  301 , and the limiting bottom plate  124  is configured to be set towards the countertop of the window sill  302 . Optionally, the limit bottom plate  124  is configured to abut the countertop of the window sill  302 . 
     Further, as shown in  FIGS. 5 to 7 , the lateral extension member  13  further includes an extension mounting portion  134 . The extension mounting portion  134  is disposed at an end of the extension bottom plate  131  away from the lateral limiting member  12 . The extension mounting portion  134  is configured to connect with the side wall of the window. In this way, by providing the extension mounting portion  134 , the lateral extension member  13  can be fixed on the side wall of the window, so that the lateral fixation member  1  can fixedly abut against the inner side of the window frame  301 . 
     As shown in  FIG. 6 , the extension mounting portion  134  includes an extension mounting plate  1341  that is bent and extended from one end of the extension bottom plate  131  away from the lateral limiting member  12  to one side, and the extension mounting plate  1341  is configured to connect with the side wall of the window. The extension mounting plate  1341  is configured for fitting with the side wall of the window for connecting with the side wall of the window. 
     In some embodiment, the extension mounting plate  1341  is provided with connecting via holes (not shown). Fasteners (screws, etc.) (not shown) pass through the connecting via holes and are used for threaded connection with the side wall of the window. The connecting via hole may be a threaded hole to improve connection strength and connection stability. 
     In some embodiment, the extension mounting plate  1341  and the extension side plate are located on the same side of the extension bottom plate  131 . 
     Further, as shown in  FIG. 6 , the extension mounting portion  134  further includes two extension reinforcement plates  1342  disposed at opposite sides of the extension mounting plate  1341 , The extension reinforcement plate  1342  is disposed inside or outside the extension side plate of the lateral extension member  13 . Specially, the two extension reinforcement plates  1342  are a first extension reinforcement plate and a second extension reinforcement plate. The first extension reinforcement plate corresponds to the first extension side plate  132 , and the second extension reinforcement plate corresponds to the second extension side plate  133 . Moreover, the first extension reinforcement plate is provided inside or outside the first extension side plate  132 , and/or the second extension reinforcement plate is provided inside or outside the second extension side plate  133 . 
     In this way, the structural strength of the extension mounting portion  134  can be enhanced to enhance the connection stability of the extension mounting portion  134  and the side wall of the window. 
     In some embodiment, the extension reinforcement plate  1342  is provided outside the extension side plate. 
     In some embodiment, the extension reinforcement plate  1342  is fixedly connected to the extension side plate (such as welding, or screw structure connection, etc.). 
     Further, as shown in  FIGS. 1, 2 and 5 , the connection member  20  is provided at the window, and the connection member is configured to connect the window air conditioner  200  and the support bracket  10 . 
     In an embodiment, the upper end (i.e., one end) of the connection member  20  is configured to connect to the window air conditioner  200 , and the lower end (i.e., the other end) of the connection member  20  is connected to the support bracket  10 . In some other embodiments, the connection member  20  is substantially horizontal. One end of the connection member  20  (that is, the end near the window air conditioner  200 ) is configured to connect to the window air conditioner  200 , and the other end (that is, the end away from the window air conditioner  200 ) is connected to the support bracket  10 . 
     In a specific embodiment, the connection member  20  may be provided inside the window frame  301  (i.e., the side towards the indoor) or outside the window frame  301  (i.e., the side towards the outdoor). 
     When the connection member  20  is provided inside the window frame  301 , the connection member  20  may limit the window air conditioner  200 . For example, when the window air conditioner  200  is lifted upwards, the connection member  20  may pull the window air conditioner  200  to prevent the window air conditioner  200  from being lifted up to the outside. For another example, when the window air conditioner  200  is pressed down, the connection member  20  may support the window air conditioner  200  to prevent the window air conditioner  200  from being pressed down and falling to the inside. That is to say, the connection member  20  is configured to connect the support bracket  10  and the window air conditioner  200 . Not only can the window air conditioner  200  be prevented from being lifted up to the outside, but also the window air conditioner  200  can be prevented from being pressed down and falling to the inside, thereby improving the mounting stability of the window air conditioner  200 . 
     When the connection member  20  is provided outside the window frame  301 , the connection member  20  may limit the window air conditioner  200 . For example, when the window air conditioner  200  is lifted upwards, the connection member  20  may pull the window air conditioner  200  to prevent the window air conditioner  200  from being lifted up to the outside. For another example, when the window air conditioner  200  is pressed down, the connection member  20  may support the window air conditioner  200  to prevent the window air conditioner  200  from being pressed down and falling to the inside. That is to say, the connection member  20  is configured to connect the support bracket  10  and the window air conditioner  200 . Not only can the window air conditioner  200  be prevented from being lifted up to the outside, but also the window air conditioner  200  can be prevented from being pressed down and falling to the inside, thereby improving the mounting stability of the window air conditioner  200 . 
     Therefore, in the technical solutions of the present disclosure, the connection member  20  is configured to connect the support bracket  10  and the window air conditioner  200 . Not only can the window air conditioner  200  be prevented from being lifted up to the outside, but also the window air conditioner  200  can be prevented from being pressed down and falling to the inside, thereby improving the mounting stability of the window air conditioner  200 . 
     In this embodiment, the connection member  20  is disposed inside the window frame  301 . In this way, the connection member  20  only needs to be installed indoors and has a large mounting space, so that the connection member  20  can be easily installed. 
     Specially, the lower end (i.e., the other end) of the connection member  20  is connected to the lateral extension member  13 . 
     Further, as shown in  FIGS. 1, 2, 5 and 6 , the upper end (i.e., one end) of the connection member  20  is configured to connect to the side of the window air conditioner  200 . Specifically, the upper end (that is, one end) of the connection member  20  is configured to be provided at one side of the window air conditioner  200 , such that the upper end (i.e., one end) of the connection member  20  is configured to connect to the side of the window air conditioner  200 . In this way, not only the mounting space of the connection member  20  but also the acting force arm of the connection member  20  and the window air conditioner  200  can be increased, so that the mounting stability of the window air conditioner  200  can be improved. Of course, in some other embodiments, the upper end (i.e., one end) of the connection member  20  may also be connected to the bottom of the window air conditioner  200 . Or, the upper end (i.e., one end) of the connection member  20  may be connected to both the bottom of the window air conditioner  200  and the side of the window air conditioner  200 . 
     Further, the connection member  20  includes a plurality of (larger than or equal to two) support connection positions sequentially distributed in the direction from the outdoor side of the window air conditioner  200  towards the indoor side. A plurality of the support connection positions are configured to selectively connect with the window air conditioner  200 . It can be understood that the direction in which the outdoor side of the window air conditioner  200  faces the indoor side is the direction in which one end of the support bracket  10  faces the other end, that is, the length direction of the support bracket  10 . 
     As such, when the window air conditioner  200  is placed at the support bracket  10 , it can be moved (appropriately) indoors or outdoors (i.e., in the length direction of the support bracket  10 ). Therefore, the position of the window air conditioner  200  in the length direction of the support bracket  10  can be adjusted according to the gravity distribution of the window air conditioner  200 , etc., so as to ensure/improve the mounting stability of the window air conditioner  200 . In addition, the position of the window air conditioner  200  in the length direction of the support bracket  10  can also be adjusted according to the length of different window air conditioners  200 , to ensure the mounting stability of different window air conditioners  200 , the connection member  20  is suitable for window air conditioners  200  of different lengths. 
     Further, as shown in  FIGS. 1, 2, 5, and 6 , the connection member  20  is provided with a support connection hole  2311 , the support connection hole  2311  is an elongated hole extending in the direction from the outdoor side of the window air conditioner  200  towards the indoor side of the window air conditioner  200 , and the support connection positions are provided at the support connection hole  2311 . The window air conditioner  200  is provided with a preset connection position  202  that is cooperatively connected with the support connection hole  2311 . Specifically, the preset connection position  202  may be, but is not limited to, a screw connection hole, a stud, or the like. 
     As such, a plurality of the support connection positions are formed through the elongated holes, which can facilitate the alignment of the support connection position with the preset connection position  202  to facilitate installation. 
     In some other embodiments, the support connection positions may also be formed by other means. For example, the connection member  20  is provided with a plurality of connection holes spaced apart from each other in the direction from the outdoor side of the window air conditioner  200  towards the indoor side, so as to form a plurality of support connection positions, and so on. 
     In this embodiment, the preset connection position  202  is provided at the side of the window air conditioner  200  so that the upper end (i.e., one end) of the connection member  20  is connected to the side of the window air conditioner  200 . 
     In this embodiment, the support connection positions are provided at the upper end (i.e., one end) of the connection member  20 . In some other embodiments, for example, in the embodiment in which the connection member  20  is substantially horizontal, the support connection positions are provided at the end of the supporting member close to the window air conditioner  200 . 
     The following describes the specific shape of the connection member. In an embodiment, as shown in  FIGS. 1, 2, 5 and 6 , the connection member  20  includes a first connection portion and a second connection portion connected to the first connection portion, the second connection portion is configured to connect to the mounting bracket assembly  100  (specifically, the support bracket  10 ). The first connection portion extends in a direction from the outdoor side of the window air conditioner  200  towards the indoor side, and the first connection portion is configured to connect to the window air conditioner  200 . In this way, by providing the second connection member extending in the direction from the outdoor side of the window air conditioner  200  towards the indoor side for connecting to the window air conditioner  200 , it is convenient to increase the acting force arm of the connection member  20  and the window air conditioner  200  to improve the mounting stability of the window air conditioner  200 . 
     Further, the second connection portion includes a vertical support portion extending in the up-down direction, and the first connection portion is provided at one end of the vertical support portion. The vertical support portion is connected to the window air conditioner  200  through the first connection portion. The other end of the vertical support portion is connected to the support bracket  10 .

     Further, as shown in  FIGS. 1-3 and 5 , the first connection portion (specifically, the horizontal connection plate  231 ) extends away from the window frame  301 . In this way, on the one hand, the acting force arm of the connection member  20  and the window air conditioner  200  can be increased, thereby improving the mounting stability of the window air conditioner  200 . On the other hand, the connection member  20  can also have a larger mounting space to facilitate installation. 
     The first connection portion (specifically, the horizontal connection plate  231 ) may also extend towards the outdoor. In this way, the horizontal connection plate  231  may extend through the window frame  301  to the outdoor. 
     It should be noted that when the connection member  20  is disposed outside the window frame  301 , the first connection portion (specifically, the horizontal connection plate  231 ) extends away from the window frame  301 . It is also possible to increase the acting force arm of the connection member  20  and the window air conditioner  200 , and to make the connection member  20  have a larger mounting space. 
     In some other embodiments, the vertical support portion and the first connection portion may also be provided in other shapes, such as a columnar shape or a tubular shape. 
     Further, as shown in  FIGS. 1, 2, 5 and 6 , a plurality of the support connection positions are provided at the first connection portion (specifically, the horizontal connection plate  231 ). 
     Specially, the support connection hole  2311  is provided at the first connection portion (specifically, the horizontal connection plate  231 ) to form a plurality of support connection positions; or, the first connection portion (specifically, the horizontal connection plate  231 ) is provided with a plurality of connection holes spaced in sequence in the direction from the outdoor side of the window air conditioner  200  towards the indoor side to form a plurality of support connection positions.

The horizontal fixation plate  233  extends along the length direction of the window sill  302 , and the horizontal fixation plate  233  is connected to the support bracket  10 . Optionally, the horizontal fixation plate  233  is formed by bending the lower end of the vertical support plate  232  towards one side of the vertical support plate  232 . 
     A horizontal fixation portion (specifically, the horizontal fixation plate  233 ) is provided at the lower end of the vertical support plate portion (specifically, the vertical support plate  232 ), which can facilitate connecting the connection member  20  to the support bracket  10 , and can ensure the connection strength between the connection member  20  and the support bracket  10 . It can be understood that, in some other embodiments, the lower end of the connection member  20  may be directly welded to the support bracket  10 . 
     In some other embodiments, the horizontal fixing portion may have another shape, such as columnar shape or tubular shape. 
     In some other embodiments, as shown in  FIGS. 1, 2, 5 and 6 , the horizontal fixation portion (specifically, the horizontal fixation plate  233 ) extends away from the lateral limiting member  12  to improve the supporting effect. 
     In this embodiment, the horizontal fixation portion (specifically, the horizontal fixation plate  233 ) is connected to the lateral extension member  13 . 
     Further, as shown in  FIGS. 1, 2, 5 and 6 , the connection member  20  has a plate-like structure. In this way, the structure of the connection member  20  can be simplified. 
     Specially, the vertical support plate  232  and the horizontal connection plate  231  are coplanar, and the horizontal fixation plate  233  extends to one side. In this way, when the window air conditioner is lifted or pressed down, the horizontal connection plate  231  and the vertical support plate  232  can provide a greater pulling or supporting effect, such that the function of the connection member  20  can be improved. 
     Further, the connection member  20  is movable relative to the lateral fixation member  1  (lateral extension member  13 ) in the length direction of the lateral fixation member  1  (lateral extension member  13 ), to make the connection position of the other end of the connection member  20  (horizontal fixation member) and the lateral fixation member  1  (lateral extension member  13 ) adjustable in the length direction of the horizontal extension member  13 , to apply the window air conditioner  200  with different widths; combined with the movable feature of the lateral extension member  13 , different types of windows can be applied; in turn, the applicability of the mounting bracket assembly  100  can be improved. 
     Specially, the horizontal fixation portion (the horizontal fixation plate  233 ) is connected to the lateral extension member  13  (the extension bottom plate  131 ). The connection member  20  can extend into the lateral extension member  13  from the upper opening of the lateral extension member  13 , so that the horizontal fixation portion (the horizontal fixation plate  233 ) is connected to the extension bottom plate  131 . 
     As such, the connection member  20  (horizontal fixation portion) is extended into the lateral extension member  13 , and the extension side plate (the first extension side plate and/or the second extension side plate) of the lateral extension member  13  can limit and support the connection member  20 . Therefore, the connection effect of the connection member  20  can be improved, so that the window air conditioner  200  is firmly mounted. 
     Further, as shown in  FIGS. 3-8 , the extension bottom plate  131  is provided with a plurality of (i.e., greater than or equal to two) first fixation connection holes  1311  spaced apart from each other in the longitudinal direction of the lateral extension member  13 . The horizontal fixation portion (the horizontal fixation plate  233 ) is provided with a second fixation connection hole  2331  that cooperates with the first fixation connection hole  1311 . In this way, the second fixation connection hole  2331  can be selectively connected to the first fixation connection hole  1311 , so that the connection position of the horizontal fixation plate  233  and the extension bottom plate  131  can be adjusted in the length direction of the lateral extension member  13 . 
     Specifically, fasteners (such as screws, pins, etc.) are sequentially passed through the first fixation connection hole  1311  and the second fixation connection hole  2331  to connect the horizontal fixation plate  233  and the extension bottom plate  131  to ensure the reliability of the connection member  20 . 
     Further, as shown in  FIGS. 4 and 6 , the second fixation connection hole  2331  is an elongated hole extending along the length direction of the lateral extension member  13 . In this way, the alignment range of the first fixation connection hole  1311  and the second fixation connection hole  2331  can be increased. Therefore, the connection member  20  can be moved at a small distance, so that the connection member  20  can be better connected to the side of the window air conditioner  200 . 
     In this embodiment, the second fixation connection hole  2331  can be selected to connect the two first fixation connection holes  1311  to improve the connection strength of the horizontal fixation plate  233  and the extension bottom plate  131  to improve the connection stability of the connection member  20 . 
     Further, as shown in  FIGS. 3 and 5 , two connection members  20  are provided so as to be disposed at two sides of the window air conditioner  200 , respectively. In this embodiment, the two connection members  20  are mounted at the two lateral extension members  13 , respectively. 
     Further, as shown in  FIG. 8 , the second extension side plate  133  is provided with an auxiliary connection hole  1331 , and the auxiliary connection hole  1331  can be used for cooperating with the first connection hole  1221 . In this way, any one of the lateral extension members  13  can be inserted into one end of the lateral limiting member  12  and the other end of the lateral limiting member  12 , so that the convenience of using the lateral extension member  13  can be improved. In addition, when the connection structure (e.g., the second connection hole) on the first extension side plate  132  is damaged, the second extension side plate  133  can also be connected to the lateral limiting member  12  and the like, thereby extending the service life of the lateral extension member  13 . In some embodiment, the first extension side plate  132  and the second extension side plate  133  can be used alternately to increase the service life of the lateral extension member  13 . 
     In some other embodiments, the horizontal fixation portion (the horizontal fixation plate  233 ) may also be connected to the first extension side plate  132  or the second extension side plate  133  of the lateral extension member  13 . In this solution, optionally, the vertical support plate  232  and the horizontal fixation plate  233  are coplanar, and the horizontal connection plate  231  extends to one side of the plate. The horizontal fixation plate  233  is connected to the first extension side plate  132  or the second extension side plate  133 . 
     In some other embodiments, the connection member  20  may also have other shapes, for example, the connection member includes a second connection portion and a first connection portion extending in a direction from the outdoor side of the window air conditioner  200  towards the indoor side. The second connection portion (i.e., the horizontal fixation portion) intersects the first connection portion so that the connection member has an L shape (approximately). The first connection portion is disposed near the window air conditioner to connect with the window air conditioner  200 , and the second connection portion (i.e., the horizontal fixation portion) is connected to the support bracket  10 . Of course, in some other embodiments, the connection member  20  can also be connected to other positions of the support bracket  10 , for example, the connection member  20  can be connected to the lateral limiting member  12 . In some embodiment, the connection member  20  may be connected to the support plate. 
     Further, as shown in  FIGS. 1 and 2 , the outdoor support is mounted at the support bracket  10 , and the outdoor support is used to support the wall  300  to improve the installation reliability of the window air conditioner  200 . 
     Specially, the outdoor support is an outdoor diagonal support  30 . As shown in  FIGS. 1 and 2 , the upper end (i.e., one end) of the outdoor diagonal support  30  is connected to the support bracket  10 , and the lower end (i.e., the other end) of the outdoor diagonal support  30  abuts against the wall  300 . Specifically, the upper end of the outdoor diagonal support  30  is connected to the support plate  11 . 
     As such, the outdoor diagonal support  30  supports the support plate  11  and the support bracket  10 , which can improve the mounting stability of the mounting bracket assembly  100 , thereby improving the installation reliability of the window air conditioner  200 . 
     Specifically, as shown in  FIGS. 1 and 2 , the upper end of the outdoor diagonal support  30  is connected to the outer support  113 . Further, as shown in  FIGS. 1 and 2 , the lower end of the outdoor diagonal support  30  is provided with a support foot  40  for abutment with the wall  300 . The support foot  40  includes a rotating member and a damping member, the rotating member has a rotational connection position to be rotatably connected to the lower end of the outdoor diagonal support  30 . The rotating member has a resistance acting surface for facing the wall  300 , the damping member is provided at the resistance acting surface, and the damping member is for abutting against the wall  300 . 
     As such, the rotating member can connect the outdoor diagonal support  30  and the damping member together, and the rotating member can rotate relative to the wall  300 , thereby making the support foot  40  suitable for matching with the wall  300  at different tilt angles. When the window air conditioner  200  is placed at the mounting bracket assembly  100 , the mounting bracket assembly  100  can transmit pressure to the rotating member and the damping member through the outdoor diagonal support  30 , and the damping member and the wall  300  closely fit together. Due to the higher friction coefficient of the damping member, a greater frictional force can be provided between the support foot  40  and the wall  300 . Therefore, the support foot  40  can firmly abut against the wall  300 , and the cooperation structure between the outdoor diagonal support  30  and the wall  300  can be made stronger. 
     Optionally, the surface of the damping member against the wall  300  is a non-smooth surface, so that the friction between the support foot  40  and the wall  300  can be increased. 
     Further, as shown in  FIGS. 1 and 2 , the rotation connection position (specifically, the rotation axis) is disposed near/biased to the upper end of the rotating member. In this way, on the one hand, the pressure can be better transmitted to the support foot  40 , so that the support foot  40  can more firmly abut against the wall surface to improve the stability of the support foot  40 . On the other hand, during installation, under the effect of its own gravity, the resistance action surface of the support foot  40  and the damping member  42  can naturally face the wall  300 , thereby reducing the installation difficulty. 
     In this embodiment, the rotation connection position is provided at the upper end of the rotating member. 
     Further, as shown in  FIGS. 5 and 7 , there are two support plates  11  in the length direction of the window sill  302  or in the width direction of the window air conditioner  200 , and the outdoor oblique support  30  is provided with two correspondingly. In this way, the support stability of the window air conditioner  200  can be improved. 
     Further, as shown in  FIGS. 5 and 7 , the support bracket  10  further includes a lateral connection plate  14  that connects the two support plates  11 . In this way, the support capacity of the support bracket  10  can be improved. 
     As shown in  FIGS. 5 and 7 , the lateral connection plate  14  is provided at the end of the outer support  113  that is away from the window frame  301 .
