[0056] The present invention proposes a mounting bracket assembly for installing an air conditioner outdoor unit. Specifically, the air conditioner of the present invention 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 the refrigerant, thereby reducing the difficulty of installation and realizing personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner of the present invention 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 air conditioner that extends to the outdoor side.

[0057] Please refer to Figures 1 to 9 In a first embodiment of the present invention, the mounting bracket assembly comprises:

[0058] 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 to each other, the window mounting bracket 11 can be mounted on the 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 arranged on the upper surface of the load-bearing bracket 12; and

[0059] 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 limiting member 30 that can be elastically deformed, and the other is provided with a stop portion 211. When the air-conditioning outdoor unit 102 moves to the installation position relative to the load-bearing bracket 12, the limiting member 30 can be elastically clamped in the stop portion 211.

[0060] In the technical solution of the present invention, after the air conditioner outdoor unit 102 is installed on the load-bearing bracket 12 and placed in the installation position, the position limiting member 30 can be elastically clamped on the stop portion 211 and realize the position limiting connection to the stop portion 211, thereby limiting the air conditioner outdoor unit 102 in the installation position, that is, completing the installation and fixation of the air conditioner outdoor unit 102. In this way, through the structure in which the position limiting member 30 and the stop portion 211 cooperate, the installation and fixation of the air conditioner outdoor unit 102 does not require the use of screws and corresponding screwdrivers and other tools, and the operation is more convenient, thereby improving the user experience.

[0061] Please refer to Figures 1 to 17 In the first to fourth embodiments, optionally, the limit member 30 is provided on the load-bearing bracket 12, and the stop portion 211 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 limit member 30 to elastically deform in a direction intersecting the up and down directions so as to be elastically clamped in the stop portion 211.

[0062] 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, 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.

[0063] In this embodiment, 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 the limiter 30, so that the limiter 30 is elastically deformed in a direction intersecting the up-down direction, that is, the limiter 30 is elastically deformed in a substantially horizontal plane. When the first bracket 20 follows the air-conditioning outdoor unit 102 to fall to a preset position (that is, when the air-conditioning outdoor unit 102 is in the installation position), the elastic potential energy of the limiter 30 decreases and is stuck on the stop portion 211, so that the load-bearing bracket 12 can limit the first bracket 20. In this way, only the installation operation of placing from top to bottom is required to complete the installation and fixing of the air-conditioning outdoor unit 102 on the installation bracket 101, which is more convenient to operate, thereby further improving the user experience.

[0064] Of course, in other embodiments, the limiting member 30 may be arranged on the first bracket 20, and the stop portion 211 may be arranged on the load-bearing bracket 12. At this time, the limiting member 30 can follow the air-conditioning outdoor unit 102 to fall to the preset position, and the stop portion 211 remains in the original position unchanged. In the process of falling, the limiting member 30 will be elastically deformed by the activation of the first bracket 20, and finally stuck in the stop portion 211, thereby completing the restriction of the first bracket 20 by the load-bearing bracket 12.

[0065] It should be noted that the installation method of the air-conditioning outdoor unit 102 is not limited to the above-mentioned solution of directly placing the air-conditioning outdoor unit 102 from top to bottom. 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 so that it can move along the first direction on the load-bearing bracket 12 and move to the installation position. At this time, the limiting member 30 is elastically deformed and limits the stop portion 211. That is, in this embodiment, two-step installation operations are required to place the air-conditioning outdoor unit 102 in the installation position.

[0066] 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 the direction away from the window to the installation position, the limiter 30 can be limitedly connected to the stopper 211. 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 the direction close to the window to the installation position, the limiter 30 can be limitedly connected to the stopper 211.

[0067] Please refer to Figure 5 , Fig.11 , Fig.14 and Fig.17 In the first to fourth embodiments, optionally, the first bracket 20 includes a latch 21 extending in the up-down direction, and the stopper 211 is provided on the side of the latch 21. In this way, the structure is simple and easy to implement. Of course, in other embodiments, for example, in an embodiment where the air conditioner outdoor unit 102 is first placed from top to bottom and then moved to the installation position in the first direction, the first bracket 20 may also extend in the front-to-back direction, and the first bracket 20 is not limited to the form of the latch 21, for example, the first bracket 20 is configured as a tubular structure, etc.

[0068] In the first to fourth embodiments, optionally, the lower end surface of the latch 21 is provided with a guide surface 212, the axial section diameter of the guide surface 212 is gradually reduced in the direction from top to bottom, and the stop portion 211 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 obtained by the section perpendicular to the axis of the latch 21, so that the guide surface 212 can play a good guiding role, so that the latch 21 can contact and push the stopper 30 more smoothly. Of course, in other embodiments, the guide surface 212 may not be provided, or the guide surface 212 may be provided on the stopper 30.

[0069] In the first to fourth embodiments, the stop portion 211 is optionally a stop groove provided on the side of the latch 21. In this way, both the upper groove side and the lower groove side of the stop groove can limit the stop member 30, thereby improving the connection reliability between the stop member 30 and the first bracket 20. In other embodiments, the stop portion 211 can also be a stop step convexly provided on the side of the first bracket 20, and the stop member 30 can be clamped on the upper surface of the stop step.

[0070] Please refer to Figure 5 , Figure 6 , Fig.11 , Fig.14 and Fig.17 In the first to fourth embodiments, the mounting bracket assembly may optionally further include a mounting seat 40 disposed on the load-bearing bracket 12, the mounting seat 40 including a conduit portion 41, the conduit portion 41 having a tube cavity 411 for inserting the plug 21, and a clearance port 412 communicating with the side of the tube cavity 411, the limiting member 30 including a clamping portion 31, the clamping portion 31 being able to be inserted into the tube cavity 411 from the clearance port 412, and being clamped in the stop portion 211. In this way, the conduit portion 41 can guide and limit the plug 21, which is conducive to the smooth insertion of the plug 21 into the tube cavity 411, and can also avoid the problem of the first bracket 20 shaking forward and backward and left and right on the load-bearing bracket 12. Of course, in other embodiments, the mounting seat 40 may not be provided, for example, the load-bearing bracket 12 is provided with a pin hole corresponding to the plug 21, the limiting member 30 is provided on the lower surface of the load-bearing bracket 12, and the portion of the plug 21 passing through the pin hole is provided with a stop portion 211.

[0071] Please refer to Figure 1 , Figure 2 , Fig.10 , Fig.12 , Fig.13 , Fig.15 and Fig.16In the first to fourth embodiments, optionally, in the embodiment where the air-conditioning outdoor unit 102 can be placed on the load-bearing bracket 12 from top to bottom and is in the installation position, optionally, the installation bracket assembly also includes a second bracket 72 provided at one end of the air-conditioning outdoor unit 102 away from the window bracket 11, the second bracket 72 includes a pin extending in the up-down direction, and the main bracket 10 is provided with a pin hole 131 for the pin to be adapted and inserted. In this way, in the process of the air-conditioning outdoor unit 102 being installed on the load-bearing bracket 12 from top to bottom, the pin and the pin hole 131 cooperate with each other to play a guiding role, so that the latch 21 can be more easily aligned with the tube inner cavity 411, thereby facilitating the installation operation. Of course, in other embodiments, the second bracket 72 may not be provided.

[0072] Please refer to Figure 1 , Figure 2 , Fig.10 , Fig.12 , Fig.13 , Fig.15 and Fig.16 In the first to fourth embodiments, the main bracket 10 may optionally further include a limit bracket 13, which is disposed at one end of the load-bearing bracket 12 away from the window bracket 11 and at least partially protrudes from the upper surface of the load-bearing bracket 12. In this way, the portion of the limit bracket 13 protruding from the upper surface of the load-bearing bracket 12 can limit the front side of the air-conditioning outdoor unit 102, thereby preventing the air-conditioning outdoor unit 102 from excessively moving forward and falling out of the load-bearing bracket 12. Of course, in other embodiments, the limit bracket 13 may not be provided.

[0073] In the first to fourth embodiments, further optionally, two load-bearing brackets 12 and position-limiting members 30 are each provided and installed in a one-to-one correspondence, the two load-bearing brackets 12 are respectively provided at opposite ends of the position-limiting bracket 13, the pin hole 131 is provided in the middle of the position-limiting bracket 13, and the second bracket 72 is convexly provided on the lower surface of the air-conditioning outdoor unit 102. In this way, the pin hole 131 located on the position-limiting bracket 13 and the two conduit portions 41 located on the load-bearing bracket 12 together form a triangular station, 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 131 can also be provided on the load-bearing bracket 12, for example, the pin shaft is provided at one end of the load-bearing bracket 12 away from the window bracket 11, and the pin shaft and the pin hole 131 are each provided with two, and are provided in a one-to-one correspondence with the two load-bearing brackets 12.

[0074] Please refer to Figures 1 to 6 , Figures 15 to 17In the first embodiment and the fourth embodiment, optionally, the limiter 30 further includes a fixing portion 32 connected to the clamping portion 31, and the mounting seat 40 further includes a mounting plate 42 connected to the conduit portion 41, and the fixing portion 32 is sandwiched between the mounting plate 42 and the load-bearing bracket 12. In this way, the fixing portion 32 is pressed onto the load-bearing bracket 12 by the mounting plate 42, so that the fixing portion 32 is fixed relative to the load-bearing bracket 12, and the structure is simple and easy to implement. Specifically, optionally, the mounting plate 42 is fixed to the load-bearing bracket 12 by screws. Of course, in other embodiments, the mounting plate 42 can also be fixed to the load-bearing bracket 12 by riveting, welding or bonding.

In this way, the fixing portion 32 can be reliably restricted in the receiving groove 421 by the mutual restriction of the annular retaining rib 422 and the fixing portion 32, and by the clamping force jointly applied by the mounting plate 42 and the load-bearing bracket 12, thereby facilitating the displacement stability of the clamping portion 31. Of course, in other embodiments, the receiving groove 421 and the annular retaining rib 422 may not be provided, and the fixing portion 32 may be directly fixed to the lower surface of the mounting plate 42 by welding, riveting or bonding, and then the mounting plate 42 is fixed to the load-bearing bracket 12.

[0076] It should be noted that the annular structure of the present application, such as the annular retaining rib 422, does not specifically refer to a complete circular ring structure, but includes an incomplete circular ring structure, that is, including an embodiment in which the annular retaining rib 422 is broken at one point and has two opposite ends, such as Figure 6 and Fig.17 As another example, a plurality of retaining ribs are spaced apart along the circumference of the latch 21, and the plurality of retaining ribs together form a substantially complete annular structure.
