Alternatively, the form of the mounting body is not limited to the specific form provided in the embodiment, and it is within the scope of the present application as long as the mounting body can be connected to the cover ring and provided on the vehicle body with a structure that is fittingly connected thereto.

In a preferred embodiment, as shown in fig. 1, the cover rings are circular rings, and the center point is the center of the circular ring.

In another embodiment, the cover ring may be a regular polygon, and the radial direction is a radial direction of an inscribed circle or a circumscribed circle of the regular polygon, and the central point is a center of the inscribed circle or the circumscribed circle of the regular polygon.

Specifically, the regular polygon may be a square, a regular hexagon, or a regular octagon.

Preferably, when the cover ring is circular or regular polygon, the connecting body 5 located in the inner ring area and the connecting body 5 located in the outer ring area are arranged in a staggered manner in the radial direction of the ring body 1.

Specifically, no matter connector 5 is in A region or B region, all connector 5 that are located on the inner ring district and connector 5 that are located on the outer ring district stagger the setting each other in radial direction, do not have two connectors 5 to coincide on same radial direction promptly, are the setting of staggering, and such overall arrangement is more reasonable for the overall stability of fan housing is better, has further increased the mode of fan housing, strengthens bulk strength, avoids resonating.

The arrangement intervals of the connecting bodies 5 in the inner ring area and the outer ring area can be equal or unequal, the intervals between some of the connecting bodies 5 can be equal, the intervals between all the connecting bodies 5 can be unequal, and the connecting bodies can be arranged in an irregular form.

Further, in this embodiment, as a preferred embodiment, the cover ring is circular, and the plurality of connecting bodies 5 located in the B region are uniformly arranged at intervals along the extending direction of the inner ring region or the outer ring region where the connecting bodies are located. Specifically, the plurality of connecting bodies 5 located in the B region in the inner ring region are uniformly arranged at intervals along the extending direction of the inner ring region, and the plurality of connecting bodies 5 located in the B region in the outer ring region are uniformly arranged at intervals along the extending direction of the outer ring region.

Specifically, the plurality of connecting bodies 5 located in the area a in the inner ring area are uniformly arranged at intervals along the extending direction of the inner ring area, and the plurality of connecting bodies 5 located in the area a in the outer ring area are uniformly arranged at intervals along the extending direction of the outer ring area. When the shape of the ring is circular, the extending direction is the circumferential direction.

Specifically, the area a is an area opposite to the mounting body, and the area has a high requirement on the structural strength, and the structural strength of the area needs to be balanced, so that the strength of the area is more reasonable in the whole structure, and the phenomenon of local strength weakening is avoided.

The effect of this embodiment lies in, the equal equipartition of connector 5 in A region and B region for the structural strength of two places is more balanced, has promoted the mode of whole fan housing, avoids taking place resonance.

Therefore, the circumferential spacing between the adjacent connectors 5 in the inner ring area and the outer ring area in the area B provided by the embodiment is approximately equal, so that the overall structure is more balanced and stable.

Further, any one of the connection bodies 5 located in the B region in the inner ring region is aligned in the radial direction with the midpoint of the circumferential distance between the adjacent two connection bodies 5 located in the B region in the outer ring region. That is, in the B region, the connecting bodies 5 located on the inner ring region and the connecting bodies 5 located on the outer ring region are completely staggered, i.e., a certain connecting body 5 located on the inner ring region is aligned with the middle position of two connecting bodies 5 on the outer ring region, specifically, the centers of the circumferential distances between the two connecting bodies are aligned with the middle position of two adjacent connecting bodies 5 on the inner ring region, i.e., on the bisector of the central angle corresponding to the circumferential distance between the two connecting bodies, and the opposite connecting body 5 located on the outer ring region is also aligned with the middle position of two adjacent connecting bodies 5 on the inner ring region.
