Abstract

The present invention relates to a fan motor support for HVAC systems of motor vehicles, comprising a two-part housing (15) having a second part (20) and a first part (20′), a flexible joint (30) connecting the first and second parts (20′, 20), a plurality of internal ribs (40) arranged inside the first and second parts (20′, 20) of the two-part housing (15), locking the motor radially, and at least one pair of projections (50) arranged inside the first and second parts (20′, 20) of the two-part housing (15), locking the motor axially.

Claims

1. A fan motor support for HVAC systems of motor vehicles, the support comprising:

a two-part housing having a first part and a second part;

a flexible joint connecting the first and second parts;

a plurality of internal ribs arranged inside the first and second parts of the two-part housing, locking the motor radially; and

at least one pair of projections arranged inside the first and second parts of the two-part housing, locking the motor axially.

2. The support according to claim 1, further comprising clips for attaching the second part of the housing to the first part thereof.

3. The support according to claim 2, wherein the first and second parts may additionally be attached by one of screws or rivets.

4. The support according to claim 1, wherein the number, format and thickness of the internal ribs are determined by a type of motor housed in the fan motor support, and by the level of vibration and noise absorption to be obtained.

5. The support according to claim 1, wherein:

the second part has a channel that extends over the perimeter of the edge thereof and receives a sealing means; and

the first part further has a projection that likewise extends over the perimeter of the edge thereof and which has a profile that complements that of the channel in the second part, enclosing the seal.

6. The support according to claim 1, wherein the support is fastened to the HVAC system by means of screws, wherein tabs with holes are provided in the external part of the housing of the support and the receiving part is provided in the HVAC system.

7. The support according to claim 1, wherein the support is fastened to the HVAC system by rotation, and wherein a tab provided in the external part of the housing is fitted into a recess provided in the HVAC system.

8. The support according to claim 1, wherein the housing has holes for electrical connection of the motor.

9. The support according to claim 1, wherein shock-absorbing elements are provided at the ends of the internal ribs.

10. The support according to claim 1, further comprising an additional sealing means formed by a channel located in the second part of the housing and by a projection located in the first part of the housing.
