[0001] The utility model relates to air conditioning technology, in particular to a fan bracket of an outdoor unit of an air conditioner. Background Art

[0002] The fan motor of the air conditioner outdoor unit is one of the most important parts of the air conditioner. The outdoor fan cools down and dissipates the high-pressure and high-temperature gas discharged from the indoor unit, accelerating the heat exchange. Therefore, the stable and reliable operation of the fan motor is very important. The air conditioner outdoor unit fan motor (fan) is usually fixed on a fan bracket, and the fan bracket is installed inside the air conditioner outdoor unit casing. It is an important component for supporting the entire fan and fan blades.

[0003] The existing fan bracket directly passes through the mounting hole on the bracket and is directly fixed to the bracket by bolts. The fan and the mounting frame are in direct contact. Since the mounting plate is usually a sheet metal, the strength of the thinner sheet metal is low. During use, it is easy to cause the fan motor to deviate, fall, collapse, and the fan and the air guide ring to interfere and rub. The installation reliability of the fan motor is low, affecting the normal use of the air conditioner.

[0004] The patent document with patent publication number CN116989395A discloses a mounting bracket structure for an air conditioner outdoor unit fan motor. The mounting bracket of the fan motor has two mounting parts protruding outward, an upper reinforcing cross plate and a lower reinforcing cross plate, thereby enclosing a central space for installing the fan motor. The body of the fan motor passes through the central space and is fixed by bolts at four corners to achieve installation. However, this mounting part is not integrated, and the mounting part and the bracket may be separated, resulting in insufficient strength. Utility Model Content

[0027] The utility model is further described below in conjunction with the accompanying drawings.

[0028] according to Figure 1-Figure 3 As shown, the embodiment of the present application proposes an air conditioner outdoor unit fan bracket, including a bracket body 1, the bracket body 1 includes a mounting surface 23 for fixing and connecting the fan, the mounting surface 23 is provided with a mounting hole 3, the bracket body 1 is integrally provided with a reinforcing portion 2, the reinforcing portion 2 extends along the axial direction of the mounting hole 3 in the direction toward which the mounting surface 23 faces, and the mounting hole 3 is provided in the reinforcing portion 2. In other words, the reinforcing portion 2 can be specifically regarded as a thickening layer with a certain thickness. After the fan is installed on the bracket body 1, during use, the high-speed rotation of the fan will generate some forces acting on the bracket body 1, and the reinforcing portion 2 integrally connected to the bracket body 1 enhances the strength of the fan installation part, so that the defect that the sheet metal is easily deformed by force can be avoided. Specifically, the reinforcing portion 2 can be a solid block-shaped thickening layer, and the thickness direction extends along the axial direction of the mounting hole 3. The specific thickness size is set according to the actual size of the air conditioner outdoor unit. The integrated design can be convenient for processing and has better connection strength.

[0029] In addition, specifically, the reinforcing portion 2 can be a convex hump, the structure of the convex hump is convex in the extension direction, and the back side of the opposite side is concave, and this continuously extended convex hump can well disperse the stress acting after the fan motor is installed, so that the fan installed on the bracket body 1 has sufficient strength, and will not cause stress concentration on the connection position of the bracket body 1 due to long-term shaking of the fan and its own gravity, resulting in defects such as deviation, falling, and collapse, and the convex hump is convenient for stamping and forming processing, which is easy to process and requires less investment. Specifically, the convex hump can form a convex structure around the mounting hole 3. The structure improves the rigidity and strength of the bracket body 1 in this area. The principle is that this design can reduce local stress concentration and make the bracket body 1 more durable and stable. If only the mounting hole 3 is directly opened on the flat plate and then the fan is installed, the fan will exert a downward force on the bracket body 1 due to gravity, and the stress will be concentrated on the lower edge of the mounting hole 3, directly causing the bracket body 1 to deform or be damaged. Therefore, this convex package structure for assembling the fan can be stronger and less prone to deformation. It is particularly important for installation structures that need to withstand large tensile or shear forces. At the same time, it is also beautiful and simple.

[0030] At the same time, by processing the raised height of the bulge, the axial distance of the fan after assembly can be changed; and the strength design can design the most suitable bulge height by designing the height of the bulge, the installation position of the bracket and the weight of the motor.

[0031] The corners of the protruding part of the above-mentioned bulge are chamfered, and the end of the bulge close to the fan blade is a mounting plane. The mounting hole 3 is opened on the mounting plane, and 4 connecting holes for installing screws are evenly spaced along the circumference of the mounting hole 3 on the mounting plane. During the specific installation process, the installation position of the fan body is passed through the mounting hole 3, and the four fixing holes and four connecting holes on the fixing plate of the fan are locked by screws to ensure the installation stability.

[0032] In order to further improve the connection stability between the bracket body 1 and the fan, Figure 4 As shown, a surrounding edge 4 is provided on the edge of the mounting hole 3 for snapping into the body mounting portion of the fan. The surrounding edge 4 can be close to the outer wall of the mounting portion of the fan to produce a certain supporting effect, making the connection portion more stable, and the surrounding edge 4 is provided with a notch 5 for snapping into the fan, which is used to snap into a specific abutment position of the motor body to achieve a better locking effect. In addition, baffles 6 are provided on both sides of the notch 5. The baffles 6 are specifically located at the extended positions along the surrounding edges 4 on both sides of the notch 5. The baffles 6 are snapped into the fan mounting portion to ensure that the connection on both sides of the fan is more stable, and the extension directions of the surrounding edge 4 and the baffle 6 are opposite to the extension direction of the bulge, that is, the baffle 6 and the surrounding edge 4 are both located in the recessed position on the back side of the bulge.

[0033] Moreover, a wire hanging groove 18 is opened on the edge of the above-mentioned bracket body 1, and the above-mentioned bracket body 1 is provided with a wire buckle 17, and the above-mentioned wire buckle 17 is located below the above-mentioned notch 5. The wire hanging groove 18 and the wire buckle 17 can gather and comb the lines extending downward from the fan, which is convenient for wiring and can improve the aesthetics.

[0034] like Figure 1 , Figure 2 As shown, the bracket body 1 is provided with at least one main reinforcing rib 10 along the length direction. The main reinforcing rib 10 is concave. The strength of the bracket body 1 can be enhanced by the provision of the main reinforcing rib 10. Preferably, there are two main reinforcing ribs 10, which are respectively provided at the edge positions on both sides of the bracket body 1.

[0035] Furthermore, the reinforcing portion 2 is located in the middle of the bracket body 1, the mounting hole 3 is located at the center of the reinforcing portion 2, and the upper and lower parts of the bracket body 1 are symmetrically arranged based on the mounting hole 3, the fan is installed at the center of the bracket body 1, and the bracket body 1 on the upper and lower sides is symmetrically arranged with the fan as the boundary. Such a structure can make the force acting on the bracket body 1 by the fan more balanced, and make the force on the bracket body 1 more uniform, thereby increasing the strength of the bracket body 1.

[0036] Specifically, Figure 5 As shown, the upper and lower ends of the bracket body 1 are respectively integrally provided with an upper mounting plate 8 and a lower mounting plate 7, the bracket body 1 is respectively perpendicular to the upper mounting plate 8 and the lower mounting plate 7, the lower mounting plate 7 is provided with at least one first angular snap-in hole 11 which is positioned and snap-fitted with the bottom plate 12 of the air-conditioning outdoor unit, and the bottom plate 12 of the air-conditioning outdoor unit is provided with a first angular snap-in block 13 adapted to the first angular snap-in hole 11, the first angular snap-in hole 11 and the first angular snap-in block 13 are snap-fitted with each other, when assembling the lower mounting plate 7 and the bottom plate 12 of the air-conditioning outdoor unit, the first angular snap-in hole 11 and the first angular snap-in block 13 can be snap-fitted with each other to form a stable snap-fitting positioning state, the hole positions of each fixing hole of the bracket body 1 and the bottom plate 12 of the air-conditioning outdoor unit can be fully aligned, and then bolts are used to fix them, so that the installation is more convenient, fast and stable, not easy to be misaligned, and the installation efficiency is improved.

[0037] In addition, the upper mounting plate 8 is provided with a folded edge 21, and the folded edge 21 is provided with at least one second angular snap-in hole for positioning and snap-fitting with the front panel 19 of the air conditioner outdoor unit, and the front panel 19 of the air conditioner outdoor unit is provided with a second angular snap-in block for snap-fitting with the second angular snap-in hole 20, thereby forming a stable matching structure and improving the stability of the entire bracket connection.

[0038] In the entire installation structure, the lower support plate bears a large support pressure. In order to increase the strength of the lower mounting plate 7 and ensure the strength of the entire structure, Figure 5 As shown, the lower mounting plate 7 is provided with a first reinforcing rib 14, the connecting portion of the lower mounting plate 7 and the bracket body 1 is provided with a second reinforcing rib 15, the lower portion of the bracket body 1 is provided with a third reinforcing rib 16 along the length direction, the third reinforcing rib 16 extends downward to the lower mounting plate 7, the first reinforcing rib 14 mainly acts on the lower mounting plate 7, so that the rigidity of the lower mounting plate 7 is enhanced and it is not easy to deform, and the second reinforcing rib 15 is in the shape of a recessed point, and is evenly spaced at the connecting bending portion between the lower mounting plate 7 and the bracket body 1 to ensure the strength of the bending portion and the connection strength between the lower mounting plate 7 and the bracket body 1, and the third reinforcing rib 16 is arranged in a manner of extending directly from the bracket body 1 to the lower mounting plate 7, further ensuring the stability between the lower mounting plate 7 and the bracket body 1 and preventing relative angle changes, the first reinforcing rib 14, the second reinforcing rib 15 and the third reinforcing rib 16 can all be multiple and cross-spaced, and through multiple reinforcement effects, the supporting strength and stability of the lower mounting plate 7 are optimized.

[0039] In order to further enhance the installation stability of the fan, Figure 6 As shown, a plurality of limit members 22 are arranged along the circumference of the mounting hole 3 near the edge of the reinforcement portion 2. The limit members 22 are used to clamp the outer wall of the fan. Specifically, the limit members 22 are limit blocks with an arc-shaped protrusion on the centripetal side, and the position of the limit hole coincides with the slot of the outer wall of some existing models of fans, so that the arc-shaped protrusion of the limit block is directly clamped with the slot, ensuring that the fan will not rotate or deviate relative to the mounting hole after installation, thereby increasing the stability of the installation structure.

[0040] In addition, Figure 1 , 3 As shown, a Z-shaped buckling plate 9 for setting the condenser is also provided on the back side of the upper mounting plate 8, which reduces the mounting gap, facilitates the stable installation of the condenser, and can ensure the stability of the overall structure inside the air conditioner outdoor unit.
