[0050] Note that, in the description, the same reference numerals are assigned to the same elements and repeated description is omitted.

[0051] ​Also, in the following description, unless specifically stated otherwise, "front", "rear", "upper", "lower", "inner", "outer" refer to "front", "rear" in the vehicle front-rear direction, "upper", "lower" in the vehicle up-down direction, "inner", "outer" in the vehicle inner-outer direction.

[0052] The vehicle air-conditioning apparatus S of the present embodiment is provided with a plurality of blow-out ports (not shown) on an instrument panel (not shown) that constitutes a front portion of a vehicle cabin.

[0053] Also, the air distribution passage D that communicates with each of the blow-out ports is disposed inside the instrument panel (not shown) that constitutes the front portion of the vehicle cabin, and includes a side passage SD (refer to Figure 1 ).

[0054] The side passage SD is an air distribution passage D for sending air from the front toward the rear in the vicinity of the side of the vehicle cabin.

[0055] In the present embodiment, the air distribution unit (hereinafter referred to as side unit 1) that constitutes the blow-out port of the side passage SD (refer to Figure 2 ) is described.

[0056] Note that, although not shown for ease of explanation, a side unit of the same configuration as the side unit 1 is disposed at the blow-out port of the side passage SD on the right side. Figure 2

[0057] Also, the same configuration as the side unit 1 is omitted for the side unit on the right side.

[0058] The side unit 1 is a configuration for opening and closing the side ventilation blow-out port 12 (1st blow-out port) and the side defrosting blow-out port 13 (2nd blow-out port).

[0059] Note that the side ventilation blow-out port 12 (1st blow-out port) is a blow-out port for sending air from the vicinity of the side of the vehicle cabin toward the rear of the vehicle.

[0060] Also, the side defrosting blow-out port 13 (2nd blow-out port) is a blow-out port for sending air from the vicinity of the side of the vehicle cabin toward the front seat side window.

[0061] The side unit 1 is provided with a unit housing 10, an electric motor (not shown), a side air passage valve 20 (1st valve), a side defrosting valve 30 (2nd valve), a compound cam configuration CC, and a defrosting link mechanism C3.

[0062] < Unit Housing >

[0063] The unit housing 10 has a substantially square tubular shape, forms the outer shape of the side unit 1, and has an air sending passage (refer to Figure 2 , Figure 3 ) formed inside the tube.

[0064] ​The unit case 10 is provided with a passage connection port 11, a side ventilation blowout port 12, and a side defrost blowout port 13.

[0065] That is, the inside of the unit case 10 is divided into two, one blowout port is set as the side ventilation blowout port 12 (first blowout port), and the other blowout port is set as the side defrost blowout port 13 (second blowout port).

[0066] The passage connection port 11 is connected to and communicates with an outlet portion of the side passage SD.

[0067] Thus, a downstream side air supply path of the side passage SD is formed inside the cylinder of the unit case 10.

[0068] The side ventilation blowout port 12 is opened at a front end straight to the rear from the passage connection port 11. Also, an air supply path connecting the side ventilation blowout port 12 and the passage connection port 11 is set as a side ventilation air supply path 14.

[0069] The side defrost blowout port 13 is opened adjacent to the side ventilation blowout port 12 on the vehicle width direction outer side of the side ventilation blowout port 12.

[0070] A side defrost connection port 15 is provided in an outer side wall 14a that is a vehicle width direction outer side wall forming the side ventilation air supply path 14. Also, a space connecting the side defrost blowout port 13 and the side defrost connection port 15 is set as a side defrost air supply path 16.

[0071] <Electric motor>

[0072] The electric motor (not shown) is a power source that generates power when the side ventilation valve 20 and the side defrost valve 30 are opened and closed.

[0073] The electric motor is disposed adjacent to the vehicle width direction inner side of the unit case 10.

[0074] The electric motor is coupled to the side ventilation valve 20 via a side ventilation cam mechanism C1 (first cam mechanism).

[0075] In addition, the electric motor is coupled to the side defrost valve 30 via a side defrost cam mechanism C2 (second cam mechanism) and a defrost link mechanism C3.

[0076] The electric motor is controlled in a manner that allows forward rotation and reverse rotation.

[0077] The electric motor is provided on an output shaft (not shown) thereof with a drive gear (not shown) that rotates together with the output shaft.

[0078] Note that, in the present embodiment, in Figure 6 the direction in which the cam body 40 described later is rotated counterclockwise is set as the forward rotation direction, and the direction in which the cam body 40 is rotated clockwise is set as the reverse rotation direction.

[0079] <Side air vent valve>

[0080] The side air vent valve 20 is composed of a so-called butterfly valve (refer to Figure 3 ).

[0081] The support shaft of the side air vent valve 20 (hereinafter referred to as a passage support shaft A20) extends in the vehicle width direction and is supported by the outer side wall 14a and the inner side wall 14b of the side air vent passage 14.

[0082] <Side defrosting valve>

[0083] The side defrosting valve 30 is rotatably supported and supports one side of a plate-shaped plate in a cantilever beam manner (refer to Figure 3 , Figure 7 ).

[0084] The support shaft of the side defrosting valve 30 (hereinafter referred to as a defrosting support shaft A30) extends in the vehicle up-and-down direction and is supported by the top surface 10a and the bottom surface 10b of the side defrosting passage 16.

[0085] A defrosting link arm 31 and a defrosting link pin 32 are provided at the upper end portion of the defrosting support shaft A30.

[0086] The defrosting link arm 31 is a small piece that is orthogonal to the defrosting support shaft A30 and extends along the side defrosting valve 30, and rotates together with the side defrosting valve 30.

[0087] The defrosting link pin 32 is a shaft-shaped protrusion that is parallel to the defrosting support shaft A30 and protrudes from the defrosting link arm 31 toward the lower side at a predetermined interval.

[0088] Furthermore, the defrosting link mechanism C3 is composed of the defrosting link arm 31, the defrosting link pin 32, and a defrosting link groove 62 described later.

[0089] Note that the defrosting link mechanism C3 is a configuration that rotates the side defrosting valve 30 by the end surface link 60 that moves in parallel to the vehicle width direction.

[0090] <Compound cam structure>

[0091] The compound cam structure CC is a configuration that rotates the side air vent valve 20 and the side defrosting valve 30 using an electric motor as a driving source (refer to Figure 3 ).

[0092] The compound cam structure CC includes a cam body 40, a side surface link 50, and an end surface link 60.

[0093] Furthermore, the compound cam structure CC uses the cam body 40, the side surface link 50, and the end surface link 60 to configure a side air vent cam mechanism Cl (a first cam mechanism) and a side defrosting cam mechanism (a second cam mechanism).

[0094] <cam main body>

[0095] The cam main body 40 has a substantially cylindrical shape to be rotatably supported about a center axis A40 in the vehicle up-down direction (refer to Figure 4 ).

[0096] The cam main body 40 includes a driven gear 41, a side cam 42, and an end cam pin 43.

[0097] The driven gear 41 is provided integrally with the cam main body 40 at a lower end portion of the cam main body 40.

[0098] The driven gear 41 is engaged with a drive gear (not shown) and rotates together with the cam main body 40 about the center axis A40.

[0099] That is, the driven gear 41 rotates together with the cam main body 40 in conjunction with the electric motor.

[0100] Further, the cam main body 40, the side cam 42, and the end cam pin 43 rotate.

[0101] The side cam 42 is constituted by a groove formed on a side surface of the cam main body 40.

[0102] The end cam pin 43 is formed on an upper side surface of the cam main body 40.

[0103] The end cam pin 43 is an axially shaped protrusion that protrudes upward in parallel with the center axis A40 of the cam main body 40 at a prescribed interval.

[0104] <side link>

[0105] The side link 50 is provided at a vehicle width direction inner side end portion of the side breather valve 20 (refer to Figures 3-5 ).

[0106] The side link 50 has a flat plate 51 and a side cam pin 52.

[0107] The flat plate 51 is disposed so that its plate surface is orthogonal to the passage support axis A20.

[0108] The side cam pin 52 has an axial shape that protrudes from the plate surface of the flat plate 51 toward the vehicle width direction inner side in parallel with the passage support axis A20 at a prescribed interval.

[0109] Further, the side cam pin 52 is formed so as to be able to move along the groove wall of the groove constituting the side cam 42 without wobbling within the groove.

[0110] Further, the side breather valve 20 is turned by the movement of the side cam pin 52 within the side cam 42.

[0111] <End surface link>

[0112] The end surface link 60 is composed of a long, plate-like member facing the vehicle up-down direction and extending along the vehicle width direction (see Figure 3 , Figure 6 , Figure 7 ).

[0113] Further, the end surface link 60 is disposed so as to be able to reciprocate along the vehicle width direction.

[0114] In addition, the end surface link 60 is provided with an end surface cam 61 and a defrosting link groove 62.

[0115] The end surface cam 61 is formed at the vehicle width direction inner side end portion of the end surface link 60.

[0116] The end surface cam 61 is composed of a hole in the shape of an approximately isosceles triangle formed by a 1 / 4 circle arc curved in the same manner as the movement locus of the end surface cam pin 43 and a straight line connecting both ends of the circle arc.

[0117] Further, the hole wall constituting the end surface cam 61 is set as a cam surface.

[0118] The defrosting link groove 62 is formed at the vehicle width direction outer side end portion of the end surface link 60.

[0119] The defrosting link groove 62 has a groove shape extending along the vehicle front-rear direction and opening toward the upper side.

[0120] The groove width of the defrosting link groove 62 is set to a size at which the defrosting link pin 32 is able to move in the length direction within the groove.

[0121] The side ventilation cam mechanism C1 (1st cam mechanism) performs rotation of the side air vent valve 20 in conjunction with the electric motor (see Figures 3-5 ).

[0122] The side ventilation cam mechanism C1 is composed of the aforementioned side cam 42 and the side link 50.

[0123] By rotation of the cam body 40, in the side ventilation cam mechanism C1, the side cam pin 52 is pushed by the groove wall of the side cam 42 and moves in the up-down direction.

[0124] Further, when the side cam pin 52 moves in the up-down direction, the flat plate 51 rotates with the passage support shaft A20 as the rotation axis, and the side air vent valve 20 rotates.

[0125] By rotation of the side air vent valve 20, the side ventilation blowout port 12 is opened and closed.

[0126] The side defrosting cam mechanism C2 (2nd cam mechanism) performs rotation of the side defrosting valve 30 in conjunction with the electric motor and by means of the defrosting link mechanism C3 (seeFigure 3 、 Figure 6 、 Figure 7 ).

[0127] The side defrost cam mechanism C2 is composed of the aforementioned end face cam pin 43 and the end face link 60.

[0128] By rotating the cam body 40, in the side defrost cam mechanism C2, the end face cam pin 43 moves within the end face cam 61 and pushes the end face link 60 in the vehicle width direction.

[0129] And, by pushing the end face link 60, the groove wall of the defrost link groove 62 pushes the defrost link pin 32 in the vehicle width direction.

[0130] Further, the defrost link pin 32 moves within the defrost link groove 62 while being pushed, and the side defrost valve 30 rotates.

[0131] And, the end face link 60 moves in the vehicle width direction, and the groove wall of the defrost link groove 62 pushes the defrost link pin 32 in the vehicle width direction, and the defrost link pin 32 moves within the defrost link groove 62 while being pushed, and the side defrost valve 30 rotates.

[0132] And, the side defrost valve 30 rotates, and the side defrost blowout port 13 opens and closes.

[0133] < Side ventilation blowout port: open, side defrost blowout port: closed >

[0134] Next, the opening and closing mode of the side unit 1 will be described.

[0135] First, the first mode in which the side ventilation blowout port 12 is open and the side defrost blowout port 13 is closed (hereinafter referred to as the ventilation open-defrost closed mode) will be described (refer to FIG. 6). Figures 3-7 ).

[0136] In this mode, the side cam pin 52 is located at the fully open position set above the cam body 40 in the groove of the side cam 42.

[0137] Thus, the side ventilation valve 20 opens the side ventilation blowout port 12.

[0138] In addition, in this mode, the end face cam pin 43 is located at the innermost side in the vehicle width direction in the movement locus and at the rearmost position in the vehicle front-rear direction.

[0139] That is, the end face cam pin 43 is located at the fully closed position and moves and holds the end face link 60 to the inner side in the vehicle width direction.

[0140] Thus, the side defrost valve 30 closes the side defrost blowout port 13.

[0141] < Side ventilation blowout port: closed, side defrost blowout port: closed >

[0142] Next, the 2nd mode (hereinafter referred to as the ventilation-off defrost-on mode) in which the side ventilation blowout port 12 is closed and the side defrost blowout port 13 is opened will be described (refer to FIG. 6). Figures 8-11

[0143] This mode is a state in which the cam body 40 is rotated 90 degrees in the forward rotation direction (counterclockwise when viewed from above) from the state of the ventilation-off defrost-off mode.

[0144] In conjunction with the rotation of the cam body 40, the side cam pin 52 is pressed down by the groove wall of the side cam 42 and is positioned at the fully open position set below the cam body 40.

[0145] Thus, the side ventilation valve 20 closes the side ventilation blowout port 12.

[0146] In addition, in conjunction with the rotation of the cam body 40, the end cam pin 43 directly passes through the end cam 61 without acting on the hole wall of the end cam 61.

[0147] Further, the moved end cam pin 43 is positioned at the center in the vehicle width direction and at the foremost side in the vehicle front-rear direction in the movement locus.

[0148] Thus, the end link 60 is not moved in the vehicle width direction and maintains the state in which the side defrost blowout port 13 is closed.

[0149] <Side ventilation blowout port: closed, side defrost blowout port: open>

[0150] Next, the 3rd mode (hereinafter referred to as the ventilation-on defrost-on mode) in which the side ventilation blowout port 12 is closed and the side defrost blowout port 13 is opened will be described (refer to FIG. 7). Figures 12-16

[0151] This mode is a state in which the cam body 40 is rotated 90 degrees in the forward rotation direction from the state of the ventilation-off defrost-off mode.

[0152] In conjunction with the rotation of the cam body 40, the side cam pin 52 directly passes through the side cam 42 without being pressed by the groove wall in the fully closed position of the side cam 42.

[0153] Thus, the side ventilation valve 20 maintains the state in which the side ventilation blowout port 12 is closed.

[0154] In addition, in conjunction with the rotation of the cam body 40, the end cam pin 43 pushes and presses the hole wall of the end cam 61 to the outside in the vehicle width direction, and moves the end cam 61 from the fully closed position to the fully open position.

[0155] Further, the moved end cam pin 43 is positioned at the outermost side in the vehicle width direction and at the rearmost side in the vehicle front-rear direction in the movement locus. ​​

[0156] Thus, in the end surface link 60 moved to the full open position, the side defrosting valve 30 opens the side defrosting blowout port 13.

[0157] Note that, by rotating the cam body 40 by 90 degrees from the ventilation-defrosting-on mode to the reverse direction (clockwise when viewed from above), the ventilation-defrosting-off mode is reached.

[0158] Further, by rotating the cam body 40 by 90 degrees from the ventilation-defrosting-off mode to the reverse direction, the ventilation-on-defrosting-off mode is reached.

[0159] In addition, in a case where the rotation of the cam body 40 is stopped halfway from the ventilation-on-defrosting-off mode to the ventilation-defrosting-off mode, a state where the side ventilation blowout port 12 becomes half open and the side defrosting blowout port 13 is closed is reached.

[0160] Further, in a case where the rotation of the cam body 40 is stopped halfway from the ventilation-defrosting-off mode to the ventilation-on-defrosting-off mode, a state where the side ventilation blowout port 12 becomes half open and the side defrosting blowout port 13 is closed is reached.

[0161] In addition, in a case where the rotation of the cam body 40 is stopped halfway from the ventilation-defrosting-on mode to the ventilation-defrosting-off mode, a state where the side ventilation blowout port 12 is closed and the side defrosting blowout port 13 is half open is reached.

[0162] Further, in a case where the rotation of the cam body 40 is stopped halfway from the ventilation-defrosting-off mode to the ventilation-defrosting-on mode, a state where the side ventilation blowout port 12 is closed and the side defrosting blowout port 13 is half open is reached.

[0163] Next, the effects of the present embodiment will be described.

[0164] The side ventilation cam mechanism C1 of the present embodiment couples the side surface of the cam body 40 to the side ventilation valve 20, and opens and closes the side ventilation blowout port 12 in conjunction with the rotation of the cam body 40.

[0165] Further, the side defrosting cam mechanism C2 of the present embodiment couples the end surface of the cam body 40 to the side defrosting valve 30, and opens and closes the side defrosting blowout port 13 in conjunction with the rotation of the cam body 40.

[0166] That is, by rotating the cam body 40, it is possible to adjust the opening degree of the two blowout ports.

[0167] Thus, it is possible to simplify the configuration of the side unit 1 and open and close the two blowout ports.

[0168] Further, the side ventilation cam mechanism C1 of the present embodiment is constituted by a side cam 42 and a side cam pin 52.

[0169] Thus, the constitution of the cam mechanism can be simplified, and the side unit 1 can be made small and space-saving.

[0170] In addition, the side defrosting cam mechanism C2 of the present embodiment is constituted by the end face cam 61 and the end face cam pin 43.

[0171] Thus, the constitution of the cam mechanism can be further simplified, and the side unit 1 can be made further small and space-saving.

[0172] In addition, in the present embodiment, the side ventilation blowout port 12 and the side defrosting blowout port 13 are arranged at the front end branched from the common side passage SD.

[0173] Thus, the side ventilation blowout port 12 and the side defrosting blowout port 13 can be arranged in one unit housing 10.

[0174] In addition, in the present embodiment, three opening and closing modes (ventilation open-defrosting closed mode, ventilation closed-defrosting closed mode, ventilation closed-defrosting open mode) are set.

[0175] That is, the compound cam mechanism CC is constituted so that the opening and closing degree of the side ventilation valve 20 (first valve) is driven differently from the opening and closing degree of the side defrosting valve 30 (second valve) by the rotational drive of the electric motor.

[0176] Thus, a plurality of air supply modes desired by the occupant can be provided.

[0177] Note that, in the vehicle air conditioning device S of the present embodiment, an electric motor (not shown) is adopted as the drive mechanism, but it is not limited thereto.

[0178] For example, a constitution in which the rotation operation of the cam body 40 is manually performed by the occupant can be adopted.

[0179] In the case where such a constitution is adopted, the side unit 1 can be made further small and space-saving.

[0180] In addition, in the vehicle air conditioning device S of the present embodiment, the end face cam 61 of the end face cam is constituted by a through-hole, but it is not limited thereto.

[0181] For example, a groove shape can be adopted instead of the through-hole, and the same effect as the present embodiment can be obtained.
