  However, in the sliding door mechanism of the conventional example, when the sliding door moves, the sliding tip of the sliding door comes into contact with the tip of the elastic member and an external force is applied to the tip of the elastic member. There is a problem that the part is damaged or peels off from the case.

  Accordingly, the present invention has been made to solve the above-described problems, and can prevent the tip end portion of the elastic member sealing between the sliding door and the case from being damaged or peeled off. An object of the present invention is to provide a sliding door mechanism capable of improving the performance.

  The present invention provides a case with a passage, a slide door that slides between an open position and a closed position of the passage, and the case has a sealing surface that at least a peripheral edge of the slide door is in close contact with the closed position. The sliding door includes a door body and an elastic member provided on the seal surface side of the door body, and the elastic member is in close contact with the seal surface in the closed position. The movement trajectory of the slide front end surface of the elastic member is set to a trajectory separated from the seal surface, and the elastic member contacts the seal surface at a position rearward of the slide front end surface of the elastic member. Features.

  It is preferable that a front end portion of the door body is bent in a direction away from the sealing surface of the case, and a front end portion including the slide front end surface of the elastic member is provided at the front end portion of the door main body.

  1 to 8 show an embodiment of the present invention. The sliding door mechanism M of this embodiment is provided in the vehicle air conditioner 1 shown in FIG. The vehicle air conditioner 1 includes air conditioning units 2 and 3 disposed on both sides in the vehicle width direction, and independently air-conditions a driver seat and a passenger seat in a passenger compartment (not shown).

  Each of the air conditioning units 2 and 3 is provided with an air conditioning case (case) 6 in which an evaporator 4 and a heater core 5 are arranged.

 The air conditioning case 6 has a first passage (passage) 7 through which the air that has passed through the evaporator 4 passes through the heater core 5, and a second passage (passage) 8 through which the air that has passed through the evaporator 4 bypasses the heater core 5.

 The uppermost stream of the passages 7 and 8 is provided with an outside air introduction port (not shown) for introducing outside air that is air outside the passenger compartment and an inside air introduction port (not shown) for introducing inside air that is air inside the passenger compartment. It has been.

 When the inside air and the outside air are sucked into the passages 7 and 8 by a blower (not shown), the sucked air is converted into conditioned air at a desired temperature by the evaporator 4 and the heater core 5.

 Downstream of the heater core 5, a defroster outlet 9 a that blows conditioned air into the passenger compartment, a vent outlet 9 b, and a foot outlet 9 c are provided.

  As shown in FIGS. 1 and 2, the sliding door mechanism M of the present embodiment slides between the open position and the closed position of the passages 7 and 8 to vary the mixing ratio of the hot air and the cold air. An air mix door (slide door) 11 is provided.

 The air mix door 11 includes a door main body 12 and an elastic member 13 provided on a seal surface 6a side (right side in FIG. 2), which will be described later.

 The door body 12 extends in the moving direction of the air mix door 11 and is curved toward the downstream direction of air blowing (the right direction in FIG. 2).

 The elastic member 13 is formed of a urethane foam material, and is bonded to one surface (adhesion surface) 12 a of the door body 12.

 Here, as shown in FIG. 8, the other surface 12 b of the door body 12 has a rack 14 arranged in the moving direction of the air mix door 11 and the other surface 12 b of the door body 12. A pair of left and right guide pins 15 projecting in a direction orthogonal to the moving direction is provided. The rack 14 is disposed on both the left and right sides of the door body 12. The guide pins 15 are arranged at four positions on both the left and right sides of the door body 12 and the upper and lower portions.

  In the air conditioning case 6, at least the peripheral edge of the air mix door 11 is in close contact with the closed position of the second passage 8, the drive gear 16 that meshes with the rack 14 and drives the air mix door 11, and the air mix door 11. A pair of guide grooves 17 for guiding each guide pin 15 is provided.

  The movement trajectory of the slide tip surface 13 b of the elastic member 13 is set to a trajectory that is separated from the seal surface 6 a of the air conditioning case 6.

 Here, as shown in FIG. 6B, the elastic member 13 comes into contact with the seal surface 6 a of the air conditioning case 6 at a position behind the slide front end surface 13 b of the elastic member 13.

  2 to 5, the distal end portion 12c of the door main body 12 is bent in a relatively loose curve in a direction away from the seal surface 6a of the air conditioning case 6, and is then substantially parallel to the movement locus. It is supposed to be a shape.

  On the other hand, in the configuration example shown in FIG. 6, the distal end portion 12 c of the door body 12 is bent with a relatively steep curve in a direction away from the seal surface 6 a of the air conditioning case 6.

 A distal end portion 13 a including the slide distal end surface 13 b of the elastic member 13 is provided along the distal end portion 12 c of the door body 12.

  As shown in FIG. 3, in the full cool mode, the air mix door 11 descends and closes the first passage 7, so that all the air flows through the second passage 8 and bypasses the heater core 5 to create cold air. .

 As shown in FIG. 4, in the intermediate mode, the air mix door 11 moves to the intermediate position and the passages 7 and 8 are partially opened, so that a part of the air is heated by the heater core 5 and the air at the intermediate temperature is blown. Created.

 As shown in FIG. 5, in the full hot mode, the air mix door 11 rises and closes the second passage 8, so that all the air flows through the first passage 7 and is heated by the heater core 5 to create hot air. The

 Thereby, the air mix door 11 adjusts the ratio of the ventilation which flows through the heater core 5, and the ventilation which bypasses the heater core 5. FIG. Air conditioning air at a desired temperature is generated based on this air volume ratio.

  In the above configuration, when the air mix door 11 having the door main body 12 and the elastic member 13 is slid from the open position of the second passage 8 in the air conditioning case 6 to the closed position, the slide front end surface 13b of the elastic member 13 becomes the air conditioning case 6. The elastic member 13 comes into contact with the seal surface 6a of the air conditioning case 6 at a position on the rear side of the slide front end surface 13b of the elastic member 13 through a movement track separated from the seal surface 6a.

 Thereby, the elastic member 13 is elastically deformed, the peripheral edge of the air mix door 11 and the sealing surface 6a of the air conditioning case 6 are brought into close contact with each other, and the air mix door 11 and the air conditioning case 6 are sealed.

  As described above, according to the present embodiment, by keeping the slide front end surface 13b of the elastic member 13 away from the seal surface 6a of the air conditioning case 6, an external force is applied to the slide front end surface 13b of the elastic member 13 from the air conditioning case 6 side. Can be prevented, damage to the tip portion 13a including the slide tip surface 13b of the elastic member 13 and peeling from the door body 12 can be prevented, and durability of the elastic member 13 can be improved.

(Modification)
In the said one Embodiment, although the front-end | tip part 12c of the door main body 12 is bent in the direction spaced apart from the sealing surface 6a of the air-conditioning case 6, this invention is not limited to this, Fig.7 (a), (b) As shown in FIG. 4, as a modification, the tip portion 13a of the elastic member 13 can be formed to be thin and can be recessed in a direction away from the seal surface 6a of the air conditioning case 6.

 In this case, the front end portion 12c of the door main body 12 is formed in a flat shape, and a front end portion 13a including a slide front end surface 13b of the elastic member 13 is provided along the flat front end portion 12c. Thus, when the air mix door 11 is moved, the slide front end surface 13b of the elastic member 13 can be kept away from the seal surface 6a of the air conditioning case 6, and the slide front end surface 13b of the elastic member 13 is placed on the air conditioning case 6 side. It is possible to prevent external force from being applied.

 As shown in FIG. 8, the thickness of the elastic member 13 does not change, the front end of the door body 12 is composed of a curled portion and a flat portion, and the elastic member 13a is bonded to the curled portion. By adhering the seal tip portion 13b, the adhesion stability between the door body 12 and the seal tip portion 13b can be further enhanced.

  In the one embodiment, the air mix door 11 provided in the air conditioning case 6 of the vehicle air conditioner 1 is exemplified, but the present invention is not limited to this and can be applied to other slide doors.
