Abstract

In a vehicle air-conditioner-unit attachment-part structure, an air conditioner unit is arranged to face a rear surface of a dashboard and on an occupant room side. An air conditioner unit-side fixation part that is provided on a unit case is attached to a vehicle body-side fixed part at a more vehicle rearward position than the dashboard. A displacement acceptance part that accepts a movement to a vehicle rearward direction of the unit case with respect to the vehicle body-side fixed part is provided between the air conditioner unit-side fixation part and the vehicle body-side fixed part when an impact load is input to the unit case via the dashboard from a vehicle frontward direction.

First claim

What is claimed is:

1. A vehicle air-conditioner-unit attachment-part structure which is an attachment part structure of an air conditioner unit of a vehicle, in which:
an air conditioner unit includes a plurality of air conditioner components that includes an electric component and a unit case that accommodates the plurality of air conditioner components;
an occupant room of the vehicle and a power installation room in front of the occupant room are partitioned by a dashboard;
the air conditioner unit is arranged to face a rear surface of the dashboard and on the occupant room side; and
an air conditioner unit-side fixation part that is provided on the unit case is attached to a vehicle body-side fixed part that is provided on a vehicle body at a more vehicle rearward position than the dashboard,
wherein the vehicle air-conditioner-unit attachment-part structure comprises a displacement acceptance part that allows a movement of the unit case in a vehicle rearward direction relative to the vehicle body-side fixed part upon input of an impact load to the unit case via the dashboard from a vehicle frontward direction,
the vehicle body-side fixed part includes a support bracket and either one of a slit and a shaft portion, the slit along a vehicle front-to-rear direction, the shaft portion extending in a direction which is orthogonal to an extension direction of the slit, the one provided on the support bracket,
the air conditioner unit-side fixation part includes a latch block and the other of the slit and the shaft, the other provided on the latch block,
the shaft portion is fastened and fixed to an edge portion of the slit in a state where the shaft portion is inserted in the slit, and
the shaft portion and the slit constitute the displacement acceptance part.

2. The vehicle air-conditioner-unit attachment-part structure according to claim 1 ,
wherein a front part of the unit case is fixed to the dashboard.

3. The vehicle air-conditioner-unit attachment-part structure according to claim 1 ,
wherein a front part of the unit case is butted and fixed to the rear surface of the dashboard,
the air conditioner unit-side fixation part has the slit along the vehicle front-to-rear direction and that opens in the vehicle frontward direction, and
the vehicle body-side fixed part has the shaft portion that extends in the direction which is orthogonal to the extension direction of the slit and that is inserted in the slit.

4. The vehicle air-conditioner-unit attachment-part structure according to claim 1 ,
wherein the air conditioner unit has an electric cable that extends outside,
the electric cable is latched and fixed to the unit case and is latched and fixed to the vehicle body at a position apart from the unit case, and
the electric cable that is latched and fixed to the unit case and the vehicle body has a curved or bent extra length part between a latch fixation part with respect to the unit case and a latch fixation part with respect to the vehicle body.

5. The vehicle air-conditioner-unit attachment-part structure according to claim 2 ,
wherein the air conditioner unit has an electric cable that extends outside,
the electric cable is latched and fixed to the unit case and is latched and fixed to the vehicle body at a position apart from the unit case, and
the electric cable that is latched and fixed to the unit case and the vehicle body has a curved or bent extra length part between a latch fixation part with respect to the unit case and a latch fixation part with respect to the vehicle body.

6. The vehicle air-conditioner-unit attachment-part structure according to claim 3 ,
wherein the air conditioner unit has an electric cable that extends outside,
the electric cable is latched and fixed to the unit case and is latched and fixed to the vehicle body at a position apart from the unit case, and
the electric cable that is latched and fixed to the unit case and the vehicle body has a curved or bent extra length part between a latch fixation part with respect to the unit case and a latch fixation part with respect to the vehicle body.

7. The vehicle air-conditioner-unit attachment-part structure according to claim 1 , wherein the electric component includes a heater.

8. The vehicle air-conditioner-unit attachment-part structure according to claim 7 , wherein the heater includes a PTC heater.
