[0030] In the embodiment, the bottom plate 1, the first supporting plate 2 and the second supporting plate 3 can be integrally stamped from a high-strength metal plate, the number of screw holes 31 is three and the screw holes 31 are triangularly distributed on the second supporting plate 3. Therefore, during actual use, the motor can be first fixed in the interval between the first supporting plate 2 and the second supporting plate 3, the two ends of the motor are hung on the first supporting plate 2 and the second supporting plate 3 respectively, so that the motor is installed in a suspended manner, then the impeller assembly is fixed on the three screw holes 31 of the second supporting plate 3 to form a single-side positioning and fixing structure, positioning and fixing of the impeller assembly are realized, and finally the bottom plate 1 is fixed in the equipment. It should be noted that the screw hole positions on the second supporting plate 3 are also provided with corresponding screw holes in the casing of the impeller assembly, and the casing can be installed to the side of the second supporting plate 3 through a screw.

[0031] As shown in Figure 1 As an improved specific embodiment, the bottom plate 1 is provided with fixing holes 11 at four corners. Specifically, the fixing holes 11 at the four corners are circular through holes penetrating the bottom plate 1. It should be noted that the bottom of the casing of the impeller assembly is provided with through holes corresponding to the positions of the fixing holes 11, and when the bottom plate 1 is installed on the equipment, screw holes are provided corresponding to the positions of the fixing holes 11, and finally the screw is fixed and connected with the screw hole of the equipment through the through hole of the casing, the fixing hole 11 and the screw hole of the equipment, so as to further fix the impeller assembly and ensure the stability of the impeller assembly. The fixing holes 11 at the two corners of the bottom plate 1 away from the impeller assembly only need to pass through the fixing holes 11 to be fixed and connected with the equipment, so that the fixing holes 11 at the two corners of the bottom plate 1 close to the second supporting plate 3 can form a double-side screw fixing structure for the impeller assembly on one hand and can fix the bottom plate 1 to the equipment on the other hand.

[0032] As shown in Figure 1As shown, as an improved embodiment, the bottom plate 1 is further provided with an arc-shaped sheet 12 and a reserved hole 13 on one side of the arc-shaped sheet 12.

At the same time, the notch 14 is located below the motor and communicates with the above gap. When the bottom plate 1 is fixed in the equipment, for example, fixed on the lower plate with multiple concave-convex reinforcing ribs in the equipment, at this time the notch 14 corresponds to the through slot formed by the reinforcing ribs on the lower plate, so that the notch 14 and the through slot are in communication, which can further ventilate and dissipate heat, and strengthen the heat dissipation effect of the motor.

[0034] As shown in Figure 1 As an improved embodiment, the bottom plate 1 is further provided with two fixed sheets 15 arranged on both sides of the second supporting plate 3, and the fixed sheets 15 extend away from one end of the first supporting plate 2.

The bottom of the two ends of the impeller assembly respectively abuts against the fixed sheets 15. The fixed holes 11 on the two corners of the bottom plate 1 close to the second supporting plate 3 are arranged on the two fixed sheets 15. Therefore, the impeller assembly can be fixed in the cooperation structure of the fixed sheets and the second supporting plate, which ensures the firmness and stability of the impeller assembly. It is worth noting that the first supporting plate 2 and the second supporting plate 3 can be formed by bending the rectangular bottom plate 1 after processing, which has a reasonable structure and reduces the cost.

[0037] As shown in the figure, Figures 1 to 3 As an improved embodiment, the first arc-shaped opening 21 and the second arc-shaped opening 32 are clamped with buckles 4, the two ends of the buckle 4 are provided with a clamping opening 41, and the first barb 22 and the second barb 33 are embedded in the clamping opening. Specifically, the buckle 4 is also an arc-shaped structure, the clamping opening 41 is a rectangular opening, and the buckle 4 can be stamped into shape. When the motor is actually installed, first place the two ends of the motor on the first arc-shaped opening 21 and the second arc-shaped opening 32, and then install the buckle 4, so that the first barb 22 and the second barb 33 are embedded in the clamping opening 41, realizing the fixation of the motor. Of course, when the motor needs to be disassembled, only the buckle 4 needs to be pried open, improving the disassembly efficiency of the motor.

[0038] As a specific embodiment of the improvement, the first arc-shaped opening 21 and the second arc-shaped opening 32 are provided with a damping ring (not shown in the figure). Specifically, based on the fact that the buckle 4 is also arc-shaped, the first arc-shaped opening 21, the second arc-shaped opening 32 and the buckle 4 are all semicircular structures, that is, the first arc-shaped opening 21 or the second arc-shaped opening 32 and the buckle 4 are buckled to form a clamping structure with a circular inner ring, the damping ring can be a silicone ring, and a protrusion is arranged directly below the center of the ring. The width of the damping ring is greater than the width of the buckle 4, so that the buckle 4 can be completely wrapped on the surface of the damping ring. When the motor is actually installed, the damping ring can be first sleeved on the bearings at both ends of the motor, and then the motor ends are placed in the first arc-shaped opening 21 and the second arc-shaped opening 32 correspondingly, so that the protrusion of the damping ring corresponds to the first groove 23 and the second groove 34, and then the buckle 4 is used to clamp the damping ring, thereby fixing the two ends of the motor. The stability and vibration resistance of the motor during operation can be further improved.

[0039] As a specific embodiment of the improvement, the thicknesses of the bottom plate 1, the first support plate 2 and the second support plate 3 are all 2.5 mm.
