Vehicular air conditioning apparatus
View Patent ↗A vehicular air conditioning apparatus may include a case which forms a passage for conditioned air that flows toward a vehicle interior; a partition plate which divides a space inside the case; a sliding door which moves to change a flow of the conditioned air inside the case; a rack gear provided on the sliding door; and a pinion gear which moves the sliding door by rotating while being engaged with the rack gear. The partition plate may have a guide which slidably supports an end portion of the sliding door. The case may have a seal member, and the sliding door and the seal member may be disposed to slidably oppose each other. The guide may have a cut-out portion in which the seal member is disposed, and an auxiliary guide may be provided in the cut-out portion.
1. A vehicular air conditioning apparatus comprising:
a case which forms a passage for conditioned air that flows toward a vehicle interior, the case being formed by combining a plurality of divided parts;
a partition plate which divides a space inside the case and is fixed by being sandwiched between the divided parts;
a sliding door which moves to change a flow of the conditioned air inside the case;
a rack gear provided on the sliding door; and
a pinion gear which moves the sliding door by rotating while being engaged with the rack gear,
wherein the partition plate has a guide which slidably supports an end portion of the sliding door,
each of the divided parts has a seal member that extends along a direction perpendicular to a movement direction of the sliding door,
the sliding door and the seal member are disposed to slidably oppose each other at a downstream side of an air flow of the sliding door,
the guide has a cut-out portion at the downstream side of the air flow of the sliding door so that the seal member is disposed to slidably oppose the end portion of the sliding door,
the partition plate is integrally provided with an auxiliary guide that is provided in the cut-out portion to slidably support the end portion of the sliding door, and
wherein the auxiliary guide is formed integrally with a fitting portion included in the partition plate and fitted to the seal member.
2. The vehicular air conditioning apparatus according to claim 1 ,
wherein each of the divided parts has a plurality of the seal members that are arranged along the movement direction of the sliding door, and a middle one of the plurality of the seal members in the arrangement direction thereof is fixed to the auxiliary guide.
