[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any way.

[0025] The embodiment of the present application provides a motor bracket for an air conditioner outdoor unit, such as Figure 1-Figure 3 In the embodiment shown, the motor includes: a bracket body 1 having a motor mounting hole 13, the bracket body 1 including vertical beams 11 located on the left and right sides of the motor mounting hole 13 and horizontal beams 12 located on the upper and lower sides of the motor mounting hole 13, wherein the vertical beams 11 on the left and right sides are respectively provided with first connecting parts 16, and the first connecting part 16 is configured to be fixedly connected to the motor installed in the motor mounting hole, and the horizontal beams 12 on the upper and lower sides are respectively provided with second connecting parts 17, and the second connecting part 17 is configured to be connected to the first connecting part 16.

[0026] The technical solution provided in the embodiments of the present application can improve the rigidity of the beam 12 by providing a second connecting portion 17 connected to the first connecting portion 16 on the beam 12, thereby increasing the torsional resistance of the motor bracket in the lateral direction and reducing the risk of resonance caused by the shaking of the motor and the wind wheel due to excessive speed of the wind wheel on the motor bracket. In addition, the stability of the motor installation can be improved by installing the motor through the structure composed of the first connecting portion 16 and the second connecting portion 17.

[0027] In addition, since the torsional resistance of the motor bracket is improved by enhancing the stiffness of the cross beam 12, the thickness of the bracket and the width of the vertical beam 11 can be reduced when the motor bracket has the same stiffness requirements. This can achieve lightweighting and cost reduction of the motor bracket, and can also increase the ventilation volume of the hollow part of the motor bracket.

[0028] In one embodiment, Figure 1-Figure 3 As shown, the vertical beam 11 on each side is respectively provided with two vertically arranged first connecting parts 16, and the cross beam 12 on each side is respectively provided with two transversely arranged second connecting parts 17, and each second connecting part 17 is respectively connected one-to-one to the first connecting part 16 close to it. For example, the two second connecting parts 17 on the upper cross beam 12 are respectively connected one-to-one to the first connecting part 16 close to the upper cross beam 12, and the two second connecting parts 17 on the lower cross beam 12 are respectively connected one-to-one to the first connecting part 16 close to the lower cross beam 12.

[0029] In one example, by providing a second connecting portion 17 connected to the first connecting portion 16 on the crossbeam 12, the lateral stiffness of the motor bracket is improved. Under the condition of meeting the same stiffness requirements, the thickness of the motor bracket can be reduced by 12.5%. Figure 2 ) can be reduced from 16mm to 14mm, a reduction of 12.5%, corresponding to a 1.6% increase in air volume and a 0.5dB reduction in noise.

[0030] It is understood that the number of the first connecting portions 16 on the vertical beam 11 and the number of the second connecting portions 17 on the horizontal beam 12 are not limited to Figure 1-Figure 3 As shown, the present invention is not limited to each first connection portion 16 being connected to the second connection portion 17. For example, three first connection portions 16 may be provided on the left and right sides of the vertical beam 11, respectively, with the first connection portions 16 near the upper and lower cross beams being connected to the second connection portion 17, while the first connection portion 16 in the middle is not connected to the second connection portion 17; or, a first connection portion 17 may be provided on each of the upper and lower cross beams 12, with the first connection portion 17 on the upper cross beam being connected to the first connection portion 16 on one vertical beam, and the first connection portion 17 on the lower cross beam being connected to the first connection portion 16 on the other vertical beam.

[0031] In one embodiment, the first connecting portion 16 and the second connecting portion 17 have an overlapping portion, with a connection hole 18 for connecting to the motor provided on the overlapping portion. This provides greater rigidity in the portion with the connection hole 18, as it is an overlapping portion, thereby improving the structural stability of the motor connection. It is understood that the connection hole 18 may also be provided only on the first connecting portion 16, with the second connecting portion 17 connected to the first connecting portion 16 at a location away from the connection hole 18.

[0032] exist Figure 1-Figure 3 In the example, the overlapping portion of the first connecting portion 16 and the second connecting portion 17 is configured to be fixedly connected at a first position, and a connection hole 18 is formed at a second position. A rivet hole 19 may be provided at the first position, and the overlapping portion of the first connecting portion 16 and the second connecting portion 17 are connected at the rivet hole 19 at the first position by rivets. Of course, the overlapping portion of the first connecting portion 16 and the second connecting portion 17 may also be connected at the first position by welding or other fasteners.

[0033] Alternatively, the first connecting portion 16 and the second connecting portion 17 may not be fixedly connected at the first position, but may be fixed together by fasteners passing through the connecting hole 18 when the motor is installed. Of course, it is more convenient to first fix the first connecting portion 16 and the second connecting portion 17 at the first position and then connect the motor to the connecting hole 18 using the fasteners.

[0034] In one example, the first connection portion 16 is formed by stamping a plate around the motor mounting hole 13. To enhance the rigidity of the first connection portion 16, as shown in FIG. Figure 1 As shown, a reinforcing rib 161 with one side concave and the other side convex can be formed on the plate body from which the first connecting portion 16 is formed by stamping.

[0035] In one example, the bracket body 1 is provided with an upper vent 14 formed by cutting the upper plate above the motor mounting hole 13, and a lower vent 15 formed by cutting the lower plate below the motor mounting hole 13. An upper crossbeam 12 is formed between the upper vent 14 and the motor mounting hole 13, and a lower crossbeam 12 is formed between the lower vent 15 and the motor mounting hole 13.

[0036] The second connecting portion 17 on the upper crossbeam 12 is formed by bending a portion of the upper plate toward the motor mounting hole 13, while the second connecting portion 17 on the lower crossbeam 12 is formed by bending a portion of the lower plate toward the motor mounting hole 13. In other words, the second connecting portion 17 does not need to be fixed to the crossbeam 12; it can be directly formed by bending the cut material used to form the upper vents 14 and lower vents 15. This not only facilitates manufacturing and reduces costs, but also the second connecting portion 17 is integrally formed with the crossbeam 12, further strengthening the crossbeam 12. Of course, the second connecting portion 17 can also be provided on the crossbeam 12 by, for example, welding.

[0037] In one example, the bracket body 1 is integrally formed from a plate. To enhance the rigidity and torsional resistance of the vertical beams 11 and horizontal beams 12, flanges may be provided on the vertical beams 11, and flanges may be provided on the edges of the upper vents 14 and lower vents 15. In another example, the portion of the motor bracket located between the vertical beams 11 on both sides may be integrally formed, i.e., the portion having the horizontal beams 12, the upper vents 14, and the lower vents 15 is formed from a plate, with the vertical beams 11 fixed to both sides of the plate.

[0038] In one embodiment, to facilitate installation of the motor bracket on the housing of the air conditioner outdoor unit, the motor bracket may further include an upper connecting portion 2 located at the upper end of the bracket body 1 and a lower connecting portion 3 located at the lower end of the bracket body 1. The upper connecting portion 2 and the lower connecting portion 3 are configured to be connected to the housing of the air conditioner outdoor unit. The upper connecting portion 2 may be connected to the front panel of the housing of the outdoor unit, and the lower connecting portion 3 may abut against the bottom panel of the housing of the outdoor unit.

[0039] exist Figure 1-Figure 3 In the example of , the upper connecting portion 2 and the lower connecting portion 2 are integrally formed with the bracket body 1. To enhance the structural rigidity of the upper connecting portion 2 and the lower connecting portion 3, flanges may be provided at the edges of the upper connecting portion 2 and the lower connecting portion 3, respectively, and reinforcing ribs may be provided on the upper connecting portion 2 and / or the lower connecting portion 3.
