Abstract

The invention relates to a support device (1) of a motor of a blower. The support device (1) comprises a base (2), a ring (3) which extends according to an axis and which is able to house the motor. The support device (1) also comprises at least a decoupling means (4) which connects the base (2) and the ring (3). The ring (3) comprises a first face (5) extending according to the axis and the base (2) comprises a second face (10) extending according to the axis. The decoupling means (4) is interposed between the first (5) and the second (10) faces. The decoupling means may have an “H” shape in order to absorb the vibrations caused by the motor.

2. A motor support device (1) according to claim 1, in which said decoupling means (4) includes a fourth side (14) having at least one recess (15).

3. A motor support device (1) according to claim 1, in which said decoupling means (4) has an H shape.

4. A motor support device (1) according to claim 3, in which each of said decoupling means (4) of a first radial plane (P1) is offset by an angle (β

) of between 0 and 120°

with respect to decoupling means (4) of a second radial plane (P2).

5. A motor support device (1) according to claim 3, in which at least two distinct radial planes (P1, P2) each include three decoupling means (4) distributed with an angular offset (α

) of 120°

.

6. A motor support device (1) according to claim 3, wherein said H shape of said decoupling means (4) includes an inner portion presenting said first side (11), an outer portion presenting said second side (12), and a trunk (21) interconnecting said inner and outer portions with said trunk (21) having a reduced cross-sectional area relative to said inner and outer portions.

7. A motor support device (1) according to claim 6, wherein said trunk (21) comprises a plastic material and is deformable in a direction parallel to the axis (A) to decouple said base (2) from axial movements of the motor parallel to the axis (A).

8. A motor support device (1) according to claim 1, in which at least two decoupling means (4) are distributed according to at least two distinct radial planes (P1, P2).

9. A motor support device (1) according to claim 8, in which the radial planes (P1, P2) are located one with respect to the other so that between them is the center of gravity location of a motor said ring (3) is capable of housing.

10. A motor support device (1) according to claim 8, in which each of said decoupling means (4) of a first radial plane (P1) is offset by an angle (β

) of between 0 and 120°

with respect to decoupling means (4) of a second radial plane (P2).

11. A motor support device (1) according to claim 1, including six decoupling means (4).

12. A motor support device (1) according to claim 1, in which a hood (18) is associated with said base (2) in order to form a motor support (27).

13. A motor support device (1) according to claim 12, in which said hood (18) and said base (2) are made in one piece.

14. A motor support device (1) according to claim 1, in which said base (2), said ring (3) and said decoupling means (4) form a single part.

15. A motor support device (1) according to claim 14, which is plastic.

16. A motor support device (1) according to claim 1, wherein said decoupling means (4) comprises a plastic material.

17. A motor support device (1) according to claim 16, wherein said plastic material is rubber.

18. A process for producing a motor support device (1), which includes a base (2), a ring (3) extending according to an axis (A) and capable of housing a motor with an axis and at least one decoupling means (4) connecting the base (2) and the ring (3), in which the ring (3) has a first face (5) that extends according to the axis (A) of the ring (3), and the base (2) has a second face (10) that extends according to the axis (A) of the ring (3), the decoupling means (4) being interposed between the first (5) and the second (10) faces with the decoupling means (4) configured to decouple the base (2) from movements of the motor, characterized in that the decoupling means (4) has a six-sided shape including a first side (11) in direct contact with the ring (3), a second side (12) in direct contact with the base (2), and a free third side (13) extending substantially radially relative to the axis (A) of the ring (3) between the first and second sides (11, 12), and in that the third side (13) has at least one recess (15) extending in a direction substantially parallel to the axis (A) of the ring (3), wherein the second face (10) of the base (2) includes ridges (17) extending from the second face (10) toward the ring (3) with the ridges (17) defining a plurality of housings (24) for receiving the second side (12) of a respective one of the decoupling means (4) with each of the housings (24) having a trapezoid shape such that each of the housings (24) get narrow along the axis (A) and the second side (12) of the decoupling means (4) having a trapezoid shape for cooperating with the trapezoid shape of the housings (24) to connect the decoupling means (4) to the base (2), with the base (2), the ring (3) and the decoupling means (4) forming a single part, said process comprising the following steps:
