[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1—3, an embodiment of the utility model proposes a reliable installation structure of a motor bracket, including a box body 1, a sound insulation board 2 and a main control box 4. The sound insulation board 2 is fixedly arranged in the box body 1 to divide the box body 1 into a first chamber and a second chamber. A mounting frame 3 is fixedly arranged in the first chamber. A through groove is opened on the sound insulation board 2 for the main control box 4 to pass through. The main control box 4 is inserted into the through groove, and its two ends are respectively located in the first chamber and the second chamber. The bottom of the main control box 4 is fixedly connected to the sound insulation board 2, and the main control box 4 is located at one end of the first chamber and is connected to the mounting frame 3. In this embodiment, the sound insulation board 2 divides the box body 1 into a first chamber and a second chamber to form two working areas. The motor that drives the fan to rotate is installed on the mounting frame 3. The mounting frame 3 is fixed in the first chamber of the box body 1 by screws. A through groove is provided on the top of the sound insulation board 2. The main control box 4 is horizontally inserted into the through groove and the bottom of the main control box 4 is fixed to the sound insulation board 2, so that the two ends of the main control box 4 are respectively located in the first chamber and the second chamber. The main control box 4 is connected to the mounting frame 3 at one end located in the first chamber to limit the horizontal movement of the mounting frame 3, so that the mounting frame 3 is not only fixed in the front and rear directions in the box body 1 by screws, but its horizontal displacement is also limited by the main control box 4, thereby reducing the influence of the vibration generated by the motor during operation on the screws, improving the stability and reliability of the motor operation, and reducing the maintenance workload.

[0021] like Figure 2 As shown, further, it also includes: a connecting member 5, the connecting member 5 connects the main control box 4 with the inner wall of the box body 1, and the connecting member 5 includes: a vertical plate 51, one end of the vertical plate 51 is fixedly connected to the main control box 4, and the other end of the vertical plate 51 is connected to an inclined plate 52, and the end of the inclined plate 52 away from the vertical plate 51 is fixedly connected to the inner wall of the box body 1. In this embodiment, the vertical plate 51 and the inclined plate 52 are both located in the second chamber, and the inclined plate 52 is fixedly connected to the inner wall of the box body 1 after tilting toward the direction of the inner wall of the box body 1. One end of the main control box 4 is fixed to the inner wall of the box body 1 through the vertical plate 51 and the inclined plate 52, which increases the fixing points of the main control box 4, improves the overall rigidity, and further limits the displacement and vibration of the mounting frame 3. In addition, multi-point fixing can disperse the vibration force generated when the motor is running, thereby reducing the possibility of screw loosening.

[0022] like Figure 2 As shown, further, the vertical plate 51 and the inclined plate 52 are connected by a horizontal plate 53. In order to improve the overall compactness of the box body 1, a horizontal plate 53 is provided between the vertical plate 51 and the inclined plate 52, and components, such as an electric controller, can be installed on the horizontal plate 53, so that the space in the box body 1 can be fully utilized.

[0023] like Figure 2As shown, further, the edge of the inclined plate 52 adjacent to the horizontal plate 53 and the edge away from the horizontal plate 53 are both folded inward 54. Specifically, in this embodiment, the folding direction 54 of the edge of the inclined plate 52 is folded 54 toward the bottom of the horizontal plate 53, wherein the edge of the inclined plate 52 adjacent to the horizontal plate 53 is folded 54 and abuts against the bottom of the horizontal plate 53 after being folded 54, thereby forming a support structure for the horizontal plate 53 and improving the support strength of the horizontal plate 53, and the edge of the inclined plate 52 away from the horizontal plate 53 is folded 54 to open a connection hole, so as to facilitate its connection with the inner wall of the box body 1.

[0024] like Figure 2 As shown, further, the vertical plate 51, the inclined plate 52 and the horizontal platform are integrally formed. The integrally formed structure enhances the connection stability between the main control box 4 and the box body 1, and effectively disperses and conducts stress.

[0025] like Figure 3 As shown, further, a transfer ear 6 is fixedly provided at the bottom of the main control box 4, a fixing stud 7 is provided on the side wall of the transfer ear 6, and a mounting hole 8 for the fixing stud 7 to pass through is opened on the vertical plate 51. In this embodiment, when the vertical plate 51 is connected to the main control box 4, the fixing stud 7 on the transfer ear 6 is passed through the mounting hole 8 on the vertical plate 51, and then connected to the fixing stud 7 through a nut to complete the fixed connection between the main control box 4 and the vertical plate 51.

[0026] like Figure 3 As shown, further, the transfer ear 6 is L-shaped. In this embodiment, the cross section of the transfer ear 6 is L-shaped, one end of which is fixedly connected to the bottom of the main control box 4, and the other end is perpendicular to the main control box 4, and the fixing bolt is horizontally arranged on the side wall of the end of the transfer ear 6 perpendicular to the main control box 4.

[0027] like Figure 3 As shown, further, an extension plate 9 is fixedly provided at one end of the main control box 4 close to the mounting frame 3, and the extension plate 9 is fixedly connected to the mounting frame 3. The extension plate 9 is added to the main control box 4, and the extension plate 9 is fixed to the mounting frame 3 to further enhance the stability of the overall structure. The additional fixing points provided by the extension plate 9 will help to more evenly distribute the stress between the main control box 4 and the mounting frame 3, reduce the stress concentration on a single fixing point, and extend the life of the equipment. In this embodiment, the extension plate 9 is fixed to the top of the mounting frame 3, and can also limit the displacement of the mounting frame 3 in the vertical direction.

[0028] like Figure 3As shown, further, the extension plate 9 includes a horizontal section 91 and a concave section 92, one end of the concave section 92 is fixedly connected to the horizontal section 91, and the other end of the concave section 92 is fixedly connected to the main control box 4. Specifically, the main control box 4 includes a cover plate and a body, and the two wings of the concave section 92 are respectively connected to the horizontal section 91 and the bottom of the cover plate. When the main control box 4 is connected to the mounting frame 3, the side wall of the body of the main control box 4 abuts against the side wall of the mounting frame 3, and at the same time, the bottom of the cover plate of the main control box 4 is tightly attached to the top surface of the mounting frame 3 and then fixed with screws.

[0029] like Figure 1 As shown, the utility model also provides an air source heat pump unit including the above motor bracket reliable installation structure. According to the size of the air source heat pump unit, the motor bracket reliable installation structure is adaptively changed, so that the vibration generated by the air source heat pump unit during operation is greatly reduced, the working state during operation is stable, and its service life is also improved.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
