[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0043] At present, the air outlet of the outdoor unit of the air conditioner is mainly achieved by driving the fan blades to rotate through a motor. The motor is located in the middle of the fan blades and is fixed on a specific bracket.

[0044] It is understood that the face frame is usually made of sheet metal, with the middle part cut to facilitate the placement of the grille. In order to improve the internal air outlet effect and the compactness of the internal structure, the bracket is located close to the middle of the grille. Therefore, there is no fixed connection near the bracket, and the bracket needs to be provided with a support structure extending radially from the middle of the grille. Considering the structural strength of the bracket, the bracket may be made by die-casting, and the bracket is also often provided with horizontal and vertical crisscross reinforcement ribs, resulting in the bracket occupying more space and relatively high cost.

[0045] See also Figures 1 to 6 The utility model proposes a panel bracket 100, including a face frame 110, a mounting member 120 and a plurality of connecting members 130; the face frame 110 has an air outlet channel 110a, the mounting member 120 is arranged in the air outlet channel 110a and is used to install a motor 400, and a plurality of connecting members 130 are arranged around the mounting member 120 and connect the face frame 110 and the mounting member 120.

[0046] By adopting the technical solution of this embodiment, the gravity of the motor 400 acts on the mounting member 120, and multiple connectors 130 connected to the mounting member 120 from different directions can divide the force, so that the requirements on the structural strength of the connector 130 can be relatively reduced, and more solutions can be used to process and manufacture the connector 130. In other words, the radial area of ​​the connector 130 can be relatively reduced. When the airflow flows to the connector 130, the airflow can bypass the connector 130 and continue to move forward, so the connector 130 has less impact on the air flow. Secondly, based on the structural profile of the mounting member 120 and the connector 130, the waste cut from the middle when the face frame 110 was originally manufactured can be used to process the mounting member 120 and the connector 130, thereby improving the utilization rate of materials and reducing the cost of production.

[0047] It should be noted that the air outlet channel 110a mentioned in this embodiment is a virtual concept, and does not only refer to the area bounded by the axial contour of the face frame 110. It can be understood as the air flow area inside the air-conditioning outdoor unit 10 when the panel bracket 100 is used in the air-conditioning outdoor unit 10.

[0048] Secondly, this embodiment does not limit the number of the connecting members 130 , and the number can be set according to the force applied to the mounting member 120 and the actual structural strength of the connecting members 130 .

[0049] In some feasible implementations, the number of the connecting members 130 is five, and the five connecting members 130 are evenly distributed on the periphery of the mounting member 120, and the angle between two adjacent connecting members 130 is 72°. In this way, while ensuring the stability of the mounting member 120, the space occupied by the connecting members 130 in the air outlet channel 110a can also be controlled within a certain range.

[0050] Of course, in other embodiments, the number of the connecting members 130 may also be three, four, six, seven or eight, etc.

[0051] In addition, the present embodiment does not limit the connection method between the connecting member 130 and the mounting member 120 and the face frame 110 , and they may be integrally formed, fixed by welding, or fixed by screws.

[0052] like Figure 4 As shown, in one embodiment, two ends of the connecting member 130 are respectively connected to the inner edge of the face frame 110 and the outer edge of the mounting member 120 .

[0053] That is to say, in this embodiment, the face frame 110, the connecting member 130 and the mounting member 120 are an integrated structure. In the existing technical solutions, the face frame 110 is mostly formed by stamping through a sheet metal process. In this embodiment, the connecting member 130 and the mounting member 120 can be formed together when the face frame 110 is stamped.

[0054] The technical solution of this embodiment does not require additional steps for manufacturing the connecting member 130 and the mounting member 120 , nor does it require steps for assembling the connecting member 130 , the face frame 110 , and the mounting member 120 . Compared with the prior art, the production process is simplified and the manufacturing efficiency is improved.

[0055] See also Figures 4 to 6 In one embodiment, the connecting member 130 includes a connecting portion 132 and a first flange 134 . The connecting portion 132 connects the face frame 110 and the mounting member 120 , and the first flange 134 is folded at a side edge of the connecting portion 132 .

[0056] In this embodiment, the first flange 134 and the connecting portion 132 form a mutually supporting structure, thereby improving the structural strength of the connecting member 130. The connecting portion 132 extends radially, and the first flange 134 folded relative to the connecting portion 132 does not occupy too much space in the radial direction.

[0057] Specifically, the air outlet channel 110a has an air inlet end and an air outlet end, and the first flange 134 is folded toward the air inlet end.

[0058] Optionally, the number of the first flanges 134 in the connecting member 130 is two.

[0059] Furthermore, the two first flanges 134 may be relatively close to each other, that is, the angle between the first flange 134 and the connecting portion 132 is less than 90°, so that the airflow can be guided and the wind resistance can be reduced.

[0060] like Figure 6 As shown, in order to prevent the burrs of the first flange 134 from scratching the human body during production or assembly, a protective edge 136 is provided at one end of the first flange 134 away from the connecting portion 132, and the protective edge 136 is bent.

[0061] Optionally, the protective edge 136 is bent at 180°.

[0062] In one embodiment, the face frame 110 includes a frame body 112 and a second flange 114 . The frame body 112 is hollow and the second flange 114 is folded over the inner edge of the frame body 112 . The connecting portion 132 is connected to the frame body 112 , and the first flange 134 is connected to the second flange 114 .

[0063] In this embodiment, an air outlet channel 110a is formed in the middle of the frame 112. The design of the second flange 114 can, on the one hand, improve the structural strength of the face frame 110, and on the other hand, can play a role in guiding the wind to prevent the air from radially flowing to the gap between the frame 112 and other structures, and of course, can also play a role in reducing radial vortices.

[0064] It should be emphasized that the technical solution of connecting the first flange 134 and the second flange 114 of this embodiment can further improve the integration of the connecting member 130 and the face frame 110, improve the structural strength of the connecting member 130 and the face frame 110, and reduce the possibility of the connecting member 130 vibrating and breaking under the action of airflow. Secondly, the first flange 134 and the second flange 114 connected to each other can be stamped and formed simultaneously when punching and removing the material in the middle of the face frame 110, without the need for multiple steps.

[0065] In addition, in order to facilitate the bending of the protective edge 136 , a crack-stop groove 114 a is provided at the connection between the second flange 114 and the connecting member 130 .

[0066] In one embodiment, a plurality of openings 114 b are radially formed on the second flange 114 , and the openings 114 b can be used for snap connection with other structures.

[0067] Optionally, the number of the openings 114b is five.

[0068] Of course, in some other embodiments, the first flange 134 is not directly connected to the second flange 114 .

[0069] like Figure 4 As shown, in one embodiment, a plurality of first reinforcing ribs 1122 that are recessed or raised are disposed on the frame body 112 , and the plurality of first reinforcing ribs 1122 are disposed around the second flange 114 .

[0070] It is understandable that when the face frame 110 bracket is applied to the air-conditioning outdoor unit 10, the frame body 112 mainly serves to cover the internal space of the air-conditioning outdoor unit 10, so the physical area between the inner edge and the outer edge of the frame body 112 is relatively large.

[0071] In this embodiment, the plurality of first reinforcing ribs 1122 can improve the structural strength of the frame body 112 and reduce the possibility of the frame body 112 being bent after being subjected to an axial force.

[0072] Furthermore, the shape of the first reinforcing rib 1122 can be adaptively changed according to the contours of the inner edge and the outer edge of the frame 112 .

[0073] In a feasible implementation, there are three first reinforcing ribs 1122. One of the first reinforcing ribs 1122 is located on one side of the frame 112, and the other two first reinforcing ribs 1122 are located on the other side of the frame 112 and are distributed vertically.

[0074] like Figure 5 and Figure 6 As shown, in one embodiment, the mounting member 120 includes a mounting portion 122 and a third flange 124 , the mounting portion 122 is used to fix the motor 400 , and the third flange 124 is folded over the outer edge of the mounting portion 122 ; the connecting portion 132 is connected to the mounting portion 122 , and the first flange 134 is connected to the third flange 124 .

[0075] In this embodiment, the structure and function of the third flange 124 are similar to those of the second flange 114, and both can improve the structural strength of the mounting member 120 and the connection between the connecting member 130 and the mounting member 120. For specific details, please refer to the description of the second flange 114 in the above embodiment, which will not be repeated here.

[0076] like Figure 4 As shown, in one embodiment, the mounting portion 122 is provided with an avoidance hole 122a and a plurality of mounting holes 122b. The avoidance hole 122a is used to avoid the motor 400, and the mounting hole 122b is used to install the motor 400. The plurality of mounting holes 122b are arranged around the avoidance hole 122a.

[0077] When assembling the motor 400 and the panel bracket 100 in this embodiment, the mounting member 120 and the motor 400 can be connected by screws passing through the mounting hole 122b, wherein the avoidance hole 122a can be used to accommodate part of the motor 400 structure to avoid interference between the mounting member 120 and the motor 400.

[0078] Furthermore, the avoidance hole 122a includes a first hole body and a second hole body, wherein the second hole body is arranged on the outer contour of the first hole body, wherein the first hole body is used to avoid the main body of the motor 400, and the second hole body is used to avoid the plug wire of the motor 400.

[0079] Specifically, the first hole body is circular, and the second hole body is square.

[0080] Please continue reading Figure 4 In one embodiment, along the length direction of the connecting member 130 , the panel bracket 100 is further provided with a second reinforcing rib 140 which is convexly or concavely arranged; the second reinforcing rib 140 is arranged on at least two of the mounting member 120 , the connecting member 130 and the face frame 110 .

[0081] In this embodiment, there are three options for the location structure of the second reinforcing rib 140. In the first option, the second reinforcing rib 140 traverses the connecting member 130 along the length direction of the connecting member 130 and extends to the connection between the mounting member 120 and the face frame 110. This technical solution can improve the structural strength of the connecting member 130, the connection between the connecting member 130 and the mounting member 120, and the connection between the connecting member 130 and the face frame 110.

[0082] In the second solution, the second reinforcing rib 140 is located on the connecting member 130 and the mounting member 120. This technical solution can improve the structural strength of the connection between the connecting member 130 and the mounting member 120.

[0083] In a third solution, the second reinforcing rib 140 is located on the connecting member 130 and the face frame 110. This technical solution can improve the structural strength of the connection between the connecting member 130 and the face frame 110.

[0084] Optionally, the second reinforcing rib 140 is in the shape of an elongated strip.

[0085] Furthermore, the number of the second reinforcing ribs 140 is consistent with the number of the connecting members 130 .

[0086] The utility model also provides an air-conditioning outdoor unit 10, comprising a panel bracket 100 as provided in any of the above embodiments. The specific structure of the panel bracket 100 refers to the above embodiments. Since the air-conditioning outdoor unit 10 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0087] See also Figures 1 to 3 In this embodiment, the air conditioner outdoor unit 10 further includes a housing 200, a grille 300, a motor 400 and a fan blade 500. The panel bracket 100 is fixed on the housing 200, the grille 300 is fixed in the panel bracket 100, the fan blade 500 is transmission-connected with the motor 400, and the motor 400 is fixed on the mounting member 120 of the panel bracket 100.
