As shown in fig. 1-2, the embodiment of the present application provides a motor bracket 1, the motor bracket 1 includes a bracket body 10 and a retaining wall 20, and the electrical connection wire 3 and a fastening bolt can be prevented from contacting and causing abrasion of the electrical connection wire 3.

The bracket body 10 has a motor mounting face 11, a back face 12, a mounting hole 13, and a plurality of fastening holes 14. Here, the motor mounting surface 11 and the back surface 12 are provided on opposite sides of the bracket body 10. The mounting hole 13 and the plurality of fastening holes 14 communicate with the motor mounting surface 11 and the back surface 12, respectively, and the plurality of fastening holes 14 are sequentially arranged along a ring shape around the mounting hole 13. The fastening hole 14 is used for connecting with a fastening member, and may be a threaded hole or a pin hole, etc. matching with the fastening member, which is not limited in the embodiments of the present application. Accordingly, the fastener may be a bolt or a pin.

As shown in fig. 4 to 5, when the motor 2 is mounted on the bracket body 10, the positioning end face of the motor 2 may approach the motor mounting surface 11 from the side of the motor mounting surface 11 away from the back surface 12, and may be positioned by making surface contact with the motor mounting surface 11, one end portion of the motor 2 may be inserted into the mounting hole 13, and the output shaft of the motor 2 may be positioned on the side of the bracket body 10 where the motor mounting surface 11 is away from the back surface 12. Subsequently, a fastening member may be inserted through the through hole of the motor 2 and coupled to the fastening hole 14 to fasten the motor 2 and the bracket body 10. In some embodiments, the bracket body 10 may be arranged in a vertical direction, forming a vertical mounting manner; accordingly, the motor 2 may be arranged in a horizontal direction, forming a lateral mounting.

As shown in fig. 2, the retaining wall 20 may be disposed on the back surface 12 of the bracket body 10 and between the mounting hole 13 and the fastening hole 14. Here, the retaining wall 20 protrudes beyond the rear surface 12 of the bracket body 10 to have a certain height in the axial direction of the mounting hole 13. As shown in fig. 4 to 5, when the electrical connection wire 3 of the motor 2 passes through the mounting hole 13, the electrical connection wire 3 needs to cross the retaining wall 20 before being routed on the back surface 12 of the body bracket. The retaining wall 20 can block the electrical connection line 3 from the fastening hole 14 along the extending direction of the back surface 12, and can lift the electrical connection line 3 along the axial direction of the mounting hole 13, so that the electrical connection line 3 cannot contact with a fastening member such as a fastening bolt arranged in the fastening hole 14 after crossing the retaining wall 20, and accordingly, the electrical connection line 3 cannot be worn by the fastening member, and safety risks such as electric leakage and short circuit are reduced.

The distribution pattern of the retaining walls 20 can be determined according to actual needs, and can adopt a distribution pattern such as continuous extension or interval distribution, which is not limited by the embodiment of the present application. As shown in fig. 2, in some embodiments, the retaining wall 20 may be a continuously extending, uninterrupted annular wall disposed around the mounting hole 13. In other embodiments, the retaining wall 20 may be formed by a plurality of wall portions sequentially spaced along a ring shape surrounding the mounting hole 13; illustratively, each wall portion is disposed between the fastening hole 14 and the mounting hole 13, respectively.

The structural form of the retaining wall 20 can be determined according to actual needs, and the embodiment of the present application is not limited thereto. In some embodiments, the retaining wall 20 is a flanged portion formed at an end of the mounting hole 13 near the back surface 12, the flanged portion surrounding the mounting hole 13 along a circumferential direction of the mounting hole 13; thus, the retaining wall 20 can be formed by performing a stamping process on the bracket body 10, which is simple and requires less material. In other embodiments, the retaining wall 20 may be formed by welding on the back surface 12 of the bracket body 10 after being separately formed.

The size of the retaining wall 20 can be determined according to actual needs, and the embodiment of the present application is not limited thereto. In some embodiments, the height of the retaining wall 20 in the axial direction of the mounting hole 13 is configured such that the electrical connection line 3 passing through the retaining wall 20 does not contact the fastener passing through the fastening hole 14. Thus, it is ensured that the electrical connection wire 3 does not come into contact with a fastening member such as a fastening bolt provided in the fastening hole 14 after crossing the retaining wall 20, and a preferable safety performance is obtained.

In some embodiments, the end of wall 20 distal from back 12 may have a rolled configuration. The hemming structure is formed by a hemming process, which is a process of rolling the edge of a workpiece into an arc. Based on the rolled configuration, the end of wall 20 remote from back 12 is rolled into a circular arc. Thus, sharp edges at the end edges of the retaining wall 20 can be eliminated, the electrical connection lines 3 can be prevented from being cut, the structural strength and rigidity of the end edges of the retaining wall 20 can be increased, and the mechanical properties can be improved.

In other embodiments, the end of wall 20 distal from back 12 may have a folded edge configuration. The edge folding structure is formed through an edge folding process, and the edge folding process is a machining process for tightly combining the edges of workpieces into a whole after turning the edges of the workpieces for 180 degrees by using a die or other tools. Based on the edge folding structure, the end of the retaining wall 20 far away from the back 12 is turned over 180 ° and pressed into a whole. Thus, sharp edges at the end edges of the retaining wall 20 can be eliminated, the electrical connection lines 3 can be prevented from being cut, the structural strength and rigidity of the end edges of the retaining wall 20 can be increased, and the mechanical properties can be improved.

In some embodiments, the mounting holes 13 may have an irregular shape. Therefore, on one hand, the universality of different types of motors 2 can be considered, so that various types of motors 2 can be matched and installed; on the other hand, an avoiding space can be formed between the fastening hole 14 and the wiring area, the electric connecting wire 3 is prevented from shaking to touch the outer motor 2 and the fastening piece, and the electric connecting wire 3 is prevented from being abraded, scratched or wound.

As shown in fig. 2, in some embodiments, the motor bracket 1 further includes a limiting hook portion 40 disposed on the back surface 12, and the limiting hook portion 40 is disposed on a side of the fastening hole 14 away from the mounting hole 13. The limiting hook part 40 has a hook-shaped structure, and can adopt structural forms such as an L-shaped hook, a question mark hook and the like, so that the electric connecting wire 3 is hooked by the limiting hook part 40, the electric connecting wire 3 is prevented from shaking to touch the motor 2 or a fastener, and the electric connecting wire 3 is prevented from being abraded, scratched or wound. In some examples, the hook edge of the limit catch 40 has a folded edge configuration, avoiding the electrical connection line 3 from being cut.

In some embodiments, the back 12 of the bracket body 10 is further provided with a reinforcing rib 17 for increasing the structural strength and rigidity of the region where the motor mounting surface 11 is located, and increasing the structural stability and reliability of the motor 2 when mounted on the motor mounting surface 11.

As shown in fig. 1 and 3, in some embodiments, the motor bracket 1 further includes at least one wire harness portion 30 disposed on the back side 12 of the bracket body 10. The binding part 30 is provided on the side of the fastening hole 14 away from the mounting hole 13, and one end of the binding part 30 is fixed to the rear surface 12 while the other end is freely held. The wire harness portion 30 can be bent around its fixed end with the rear face 12 toward or away from the rear face 12, thereby clamping or releasing the electrical connection wire 3. Specifically, when the electrical connection wire 3 passes through the bunching portion 30, the operator applies a biasing force to bend and deform the bunching portion 30 in a direction approaching the back surface 12 of the stent body 10, so that the electrical connection wire 3 is sandwiched between the bunching portion 30 and the back surface 12 of the stent body 10, and the electrical connection wire 3 is restrained and positioned. When the electrical connection wire 3 needs to be released for maintenance, an operator may apply a force to bend and deform the wire harness 30 in a direction away from the back surface 12 of the holder body 10, so that the electrical connection wire 3 is detached from between the wire harness 30 and the back surface 12 of the holder body 10.

In some examples, one of the wire harness portion 30 and the bracket body 10 may be provided with a male buckle 32a, and the other may be provided with a female buckle 15, and the male buckle 32a and the female buckle 15 are buckled to connect and fix the wire harness portion 30 and the bracket body 10. For example, the wire harness 30 may be provided with a male buckle 32a, the bracket body 10 may be provided with a female buckle 15, and the male buckle 32a and the female buckle 15 are engaged to connect and fix the wire harness 30 and the bracket body 10. Further, for example, the binding part 30 may be provided with a female buckle 15, the holder body 10 may be provided with a male buckle 32a, and the male buckle 32a and the female buckle 15 are engaged with each other to connect and fix the binding part 30 and the holder body 10. Here, the male snap 32a may be a flange portion such as a card portion, the female snap 15 may be a card slot, and the flange portion and the card slot are inserted and extracted to achieve engagement connection or separation.

In some examples, a side surface of the wire harness 30 is provided with a restraining rib 32b, the restraining rib 32b being parallel to the securing ends of the wire harness 30 and the backing 12. Thus, the electrical connection wire 3 can be held between the stopper rib 32b and the fixed end of the harness portion 30 and the back surface 12, so that the electrical connection wire 3 is laterally restrained in the radial direction thereof and does not come off from the free end of the harness portion 30, thereby ensuring that the electrical connection wire 3 is reliably held at the current position. It should be noted that the electrical connection wire 3 may not contact with the wire bundling portion 30 and the back surface 12 of the bracket body 10, but still be bundled by the wire bundling portion, so as to avoid abrasion of the electrical connection wire 3.

In some examples, the motor bracket 1 includes two wire harnesses 30 (hereinafter referred to as a first wire harness 31 and a second wire harness 32), and the two wire harnesses 30 are disposed on opposite sides of the mounting hole 13. Illustratively, the bending planes of the two wire harnesses 30 are perpendicular to each other, and the bending plane of the wire harness 30 is a plane where the bending locus of the wire harness 30 is located. In this way, the first wire bundling part 31 and the second wire bundling part 32 can respectively bundle the electrical connection wire 3 in two directions perpendicular to each other, so that the electrical connection wire 3 can be routed along the planned path.

For example, when the bracket body 10 is arranged in the vertical direction, the first wire harness portion 31 may be disposed below the mounting hole 13, and the second wire harness portion 32 may be disposed above the mounting hole 13. For example, the first wire bundling part 31 may not be provided with the male buckle 32a and the female buckle 15, nor provided with the limiting rib 32 b; and the second binding part 32 can be provided with a male buckle 32a or a female buckle 15 and a limiting rib 32 b.

As shown in fig. 3, in some embodiments, the stent body 10 has an outlet portion 16 adapted for the passage of an electrical connection wire 3. The electric connecting wire 3 can leave the motor bracket 1 through the wire outlet part 16, and is further electrically connected with the electric control box after passing through the middle partition plate. Illustratively, the wire outlet portion 16 has a folded edge configuration to avoid the electrical connection wire 3 from being cut when passing through the wire outlet portion 16.

In some embodiments, the motor bracket 1 further includes a top plate 50 disposed at one end of the bracket body 10. The motor bracket 1 can be fixed to an outdoor unit of an air conditioner through the top plate 50, thereby realizing reliable installation.

On the other hand, an embodiment of the present application provides an outdoor unit 100 of an air conditioner, including the motor bracket 1 and the motor 2 provided in any of the above embodiments.
