TECHNICAL FIELD
[0001] The present disclosure, in general, relates to a heating, ventilation, and air conditioning (HVAC) unit for air distribution into a cabin of a vehicle. More particularly, the present disclosure relates to a rear louver structure that facilitates easy assembly and disassembly between a duct fitted inside a floor console and a vent fitted inside a floor console cover.
BACKGROUND
[0002] Nowadays, it is desirable to install an automotive louver in a vehicle, which is used to direct cold air/hot air coming from heating, ventilation, and air conditioning (HVAC) unit into a rear part of a passenger cabin via a duct fitted into a floor console. The end of the duct is locked with a rear vent fitted inside a floor console cover to control the direction of the air as desired by a passenger.
[0003] For instance, a conventional louver structure 100 as shown in FIG. 1 includes the duct 102 fitted inside a floor console 104. The floor console 104 is generally placed on a floor and in-between front seats of a vehicle for increasing the air flow in the rear part of the passenger cabin. The end of the duct 102 is locked with the rear vent 106 fitted inside a floor console cover 108 for controlling the direction of the air coming from the HVAC unit towards the rear passengers.
[0004] As can be seen from FIGS. 1 and 2, in order to assemble the floor console cover 108 with the floor console 104, the floor console cover 108 is moved horizontally towards the floor console 104. Further, the direction of

assembly of locking claws 108-C of the floor console cover 108 with the mating claws 104-C of the floor console 104 is horizontal whereas the direction of assembly of the rear vent 106 with the duct 102 is at a predefined angle with reference to a horizontal plane.
[0005] Due to such difference in assembly directions of child components of the floor console 104 and floor console cover 108, when the floor console cover 108 is moved horizontally towards the floor console 104 during assembly, it is difficult to assemble mating surfaces 102-F, 106-F of the duct 102 and the rear vent 106 respectively as the mating surface 106-F of the rear vent 106 is to be press-fitted inside the mating surface 102-F of the duct 102.
[0006] Therefore, easy assembly of the floor console 104 and the floor console cover 108 is not possible and the forceful assembly between the floor console 104 and the floor console cover 108 may sometimes result in fouling of the mating inner components, the duct 102 and the rear vent 106, shown by a red circle in FIG.3. Further, there is a possibility of breakage of the components of the parts.
[0007] Hence, there is a need in the state of the art to provide a solution which facilitates the easy assembly between the floor console 104 and the floor console cover 108 along a direction parallel to the horizontal plane.

Further, the louver structure includes a vent fitted inside the floor console cover at the predefined angle with respect to the horizontal plane. The lower edge of the vent is formed with a wedge-shaped step that rests on the lower flange of the duct after an assembly of the floor console and the floor console cover.
[0017] In an aspect, a lower surface of the wedge-shaped step rests on a top surface of the lower flange of the duct after the assembly of the floor console and the floor console cover.
[0018] In an aspect, the wedge-shaped step formed on the vent placed inside the floor console cover rests on the lower flange formed on the duct placed inside the floor console in an air-tight manner.
[0019] In an aspect, during the assembly between the duct and the vent, an assembly direction of the duct and the vent is the same as that of an assembly direction of the floor console and the floor console cover.
[0020] In an aspect, the assembly direction between the floor console and the floor console cover is parallel to the horizontal plane.
[0021] In an aspect, during the assembly, an assembly direction of the duct and the vent is the same as that of an assembly direction of floor console claws and floor console cover claws.
