Blower motor assembly installation structure

Abstract

A blower motor assembly mounting structure includes an outer casing and a dual-shaft motor assembly. The outer casing is composed of two opposing semi-circular covers. Each semi-circular cover has a semi-circular support portion at the center of its inner edge. When closed, they together form a support ring rib. The support ring rib has at least one of three first mounting portions, each of which has a tongue slot. The dual-shaft motor assembly, located inside the outer casing, has a motor and two casings covering the motor. Each casing has a second mounting portion corresponding to each of the first mounting portions of the support ring rib. Each second mounting portion has an inserting tongue for inserting into the tongue slot of the opposing first mounting portion of the support ring rib. This allows the dual-shaft motor assembly to be fixed to the outer casing in an insert manner, facilitating quick and easy installation.

Claims

1. A blower motor assembly mounting structure, comprising: A housing, comprising two opposing, overlapping semi-circular covers, each semi-circular cover having a semi-circular support portion at the center of its inner edge, which together form a support ring rib when closed. A vortex channel is formed on each side of the support ring rib, and an air inlet is correspondingly provided at the outer end of each vortex channel. An upward-opening exhaust port is provided on the top of the housing, connecting to each vortex channel. The support ring rib is provided with at least one of three first mounting portions, each of which has a tongue-shaped groove. A dual-shaft motor assembly, disposed inside the housing, comprises: a motor having a dual-head output shaft. Two housings are used to cover the motor and support the dual-head output shaft. Each housing has a second mounting portion corresponding to each of the first mounting portions of the support ring rib. Each second mounting portion is provided with an inserting tongue for insertion into the tongue slot of each of the first mounting portions opposite to the support ring rib. Each first mounting portion is provided with a limiting flange and an elastic pad disposed thereon. The support portion of each second mounting portion can press against the elastic pad to produce an elastic buffer clamping installation effect.

2. The blower motor assembly mounting structure as described in claim 1, wherein, Each of the first mounting portions of each of the supporting ring ribs is arranged at equal angles, and the second mounting portions of each of the outer shells relative to each of the first mounting portions are arranged at equal angles.

3. The blower motor assembly mounting structure as described in claim 1, wherein, The dual-head output shaft has a circular fan blade at each end to generate airflow to draw in air through the air inlet and guide it to the air outlet through the vortex channel.

4. The blower motor assembly mounting structure as described in claim 1, wherein, The elastic pad is made of rubber ring, foam pad or silicone material.

5. The blower motor assembly mounting structure as described in claim 1, wherein, Each of the semi-circular shell covers is a one-piece molded structure made of plastic injection molding or metal molding.

6. The blower motor assembly mounting structure as described in claim 1, wherein, Each housing has a bearing at its axis to support the dual-head output shaft, and each housing has a mating piece at its end edge that can fit together. Each mating piece has several locking parts so that a fastener can fix the motor inside the housing.

7. The blower motor assembly mounting structure as described in claim 1, wherein, The exhaust vent is designed with an upward-facing opening and can be connected to a duct to guide airflow outwards.

8. The blower motor assembly mounting structure as described in claim 3, wherein, Each of the housings has several ventilation holes formed on the wall surface adjacent to the circular fan blades to provide heat dissipation.
