Description

  The present invention relates to an air conditioning member constituting an air flow path of a vehicle air conditioner.

  The vehicle is provided with a vehicle air conditioner for supplying conditioned air into the passenger compartment. Generally, an air conditioner for a vehicle is formed in a hollow air-conditioning member that forms an air flow path, blower means that is disposed inside the air-conditioning member and circulates air in the air flow path, and air that is disposed inside the air-conditioning member. It is comprised from the temperature adjustment means etc. which heat or cool the air which approached in the flow path (for example, patent document 1). Of these, the air-conditioning member has an inflow opening for introducing air from inside or outside the vehicle interior, and an outflow opening for supplying conditioned air to the interior of the vehicle interior. The device is contacted.

  Here, since the air conditioning member needs to accommodate various devices such as a blower means and a temperature adjusting means inside, the air conditioning member is composed of a plurality of divisions, and after the various devices are accommodated, the division is performed. Although it is common to integrate, in order to prevent the air leak etc. from the clearance gap between the split bodies, each split body needs to be integrated airtightly.

  For this reason, conventionally, adjacent members were fitted and integrated with each other, and a seal member made of an elastic body was inserted in a gap between the members. FIG. 4 is a diagram schematically showing the assembly structure of the split bodies in the conventional air conditioning member.

  In the assembly structure shown in FIG. 4, a fitting claw 223 that protrudes to the inner peripheral side is provided in one of the divisions 200, and a fitting hole is formed at a position facing the fitting claw 223 in the other division 100. A portion 113 is provided to fit the fitting claw portion 223 and the fitting hole portion 113 together. And the assembly | attachment of the fitting nail | claw part 223 and the fitting hole part 113 is reinforce | strengthened, the movement of the axial direction (arrow a direction in the figure) and radial direction (arrow b direction in the figure) of the divisions (100, 200) ) And the sealing member 300 is inserted in the gap between the split bodies (100, 200).

  However, in this assembly structure, when manufacturing the air-conditioning member, a process of attaching the seal member 300 to the split body (100, 200) is required, which increases the number of steps and increases the manufacturing cost. In general, the seal member 300 is made of rubber, foamed urethane, or the like. In order to assemble the split bodies (100, 200) in an airtight manner, the seal member 300 is strongly compressed and each member is compressed. It is necessary to adhere the split (100, 200) and the seal member 300 to each other. For this reason, skilled operations are required for the assembling work, and there is a problem that manufacturing loss increases and manufacturing cost increases.

  As an assembly structure that does not require the seal member 300, for example, a structure in which each of the split bodies (100, 200) is fitted and integrated by two pairs of fitting parts and fitted parts is conceivable. In this case, by moving the fitting direction of each pair of mating parts and mated parts in a direction crossing each other, movement of each split body (100, 200) in multiple directions can be restricted. The bodies (100, 200) can be assembled in an airtight manner. An example of such an assembly structure is shown in FIG. In the assembly structure shown in FIG. 5, the fitting claw 223 and the fitting hole 113 similar to those shown in FIG. 4 are fitted to restrict the axial movement of the segments (100, 200). Then, the fitting projection 115 extending in the direction intersecting with the fitting hole 113 and the fitting groove 222 extending in the direction intersecting with the fitting claw 223 are fitted to each other and the diameter of the split body (100, 200). Regulate direction movement. By fitting the fitting claw part 223 and the fitting hole part 113 and fitting the fitting projection part 115 and the fitting groove part 222, the respective segments (100, 200) are assembled in an airtight manner. .

  By the way, in the assembling structure shown in FIG. 5, the mold for molding the fitting hole portion 113 needs to be removed from the inner peripheral side (arrow c direction) or the outer peripheral side (arrow d direction) of the split body 100. There is. However, the split body 100 is formed in a shape having an internal hollow, and the mold cannot be removed on the inner peripheral side. On the other hand, since the fitting hole 113 and the fitting projection 115 extend in the crossing direction, if the mold for molding the fitting hole 113 is removed on the outer peripheral side (arrow d direction), Since the fitting protrusion 115 interferes, the fitting protrusion 115 is crushed and the respective segments (100, 200) are not stably assembled, resulting in an increase in manufacturing loss.

Furthermore, since the fitting hole portion 113 is provided, the split bodies (100, 200) are difficult to be assembled in an airtight manner, and there is a problem that air easily leaks from the inside of the air conditioning member to the outside.
