  However, even for vehicles of the same class, the distance between the duct opening and the occupant's legs (including the legs, shins, and thighs) is the width of the foot space, the mounting position of the HVAC unit body, Because it depends on various factors such as the height of the floor, it varies depending on the model. Therefore, there are some vehicle types in which the distance between the duct opening and the leg portion tends to be close. As a result, depending on how the occupant's feet are placed, for example, only one thigh is close to the duct opening and continues to receive warm air. There is a fear.

  Further, the HVAC unit main body and its peripheral parts may be exposed on the dash panel side in front of the vehicle in the foot space. In such a case, it is possible that the occupant kicks up the HVAC unit body or the like with the toes.

  In view of such problems, the present invention provides a vehicle air-conditioning structure capable of maintaining the distance between the occupant's leg and the duct opening and preventing contact between the occupant's leg and the air-conditioning unit main body. The purpose is that.

  In order to solve the above-mentioned problems, a typical configuration of a vehicle air conditioning structure according to the present invention is a vehicle air conditioning structure that performs air conditioning in a foot space below a vehicle instrument panel. An air conditioning unit body provided in the instrument panel and exposed to the foot space; a duct opening provided in the vicinity of the air conditioning unit body for blowing air from the air conditioning unit body to the foot space; and a lower portion of the air conditioning unit body And a cover member that protrudes downward from the duct opening on the vehicle front side of the duct opening.

  According to said cover member, the movement range of a passenger | crew's leg part in foot space can be controlled. Therefore, it is possible to prevent the toes from kicking up the air conditioning unit main body and the vicinity of the thighs from being too close to the duct opening.

  The vehicle air conditioning structure may further include a drain hose provided by connecting the air conditioning unit main body and the dash panel on the vehicle width direction center side in front of the vehicle with respect to the cover member. By restricting the movement range of the occupant's legs by the cover member, it is possible to prevent the toes and the like from being caught by the drain hose. Therefore, it is not necessary to dispose the drain hose so that the toes do not touch, and the degree of freedom in layout is improved.

  The air conditioning unit main body may have a connection connector that is provided above the cover member and connects to a predetermined electrical component. The connection connector can also be efficiently protected from contact with the occupant's legs by the cover member.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the vehicle air conditioning structure which can maintain the distance of a passenger | crew's leg part and a duct opening part, and can prevent a contact with a passenger | crew's leg part and an air-conditioning unit main body. .

It is done. Since the front seat side of the air conditioning unit main body 114 is covered with the instrument panel 104, the air conditioning unit main body 114 is not visible to the passengers in the front seat.

  A duct 116 is provided in the air conditioning unit main body 114 at a position on the vehicle rear side closer to the center in the vehicle width direction of the vehicle. The duct 116 is a part that sends out the air adjusted by the air conditioning unit main body 114 into the room, and has a duct opening 118 that blows out air from the air conditioning unit main body 114 in the vicinity of the air conditioning unit main body 114. The duct opening 118 may be provided at the upper part on either side of the foot space E1 in the vehicle width direction, but in this embodiment, the duct opening 118 is provided from the center in the vehicle width direction of the vehicle at the upper part of the foot space E1.

  FIG.1 (b) is the figure which showed the air conditioning structure 100 for vehicles of Fig.1 (a) seeing from the vehicle rear. The air conditioning unit main body 114 is a relatively large structure, and is attached from the left side to the center in the vehicle width direction on the vehicle rear side of the dash panel 108.

  FIG. 2 is a diagram showing each state of the vehicle air conditioning structure of FIG. FIG. 2A is a perspective view showing the vehicle air conditioning structure 100 of FIG. In the present embodiment, the cover member 120 is attached to the lower part of the air conditioning unit main body 114.

  As shown in FIG. 3B to be described later, the instrument panel 104 is open above the foot space E1, and the lower side of the air conditioning unit main body 114 may be exposed from the instrument panel 104 to the foot space E1. . The cover member 120 is attached to the lower part of such an air conditioning unit main body 114, thereby protecting the air conditioning unit main body 114 from being kicked up by an occupant.

  FIG. 2B is a diagram showing the cover member 120 of FIG. The cover member 120 has a base portion 122 that protrudes downward. Attachment portions 126 and 128 are provided on the vehicle rear side and vehicle front side of the base portion 122, respectively.

  As shown in FIG. 1B, the cover member 120 is attached to the air conditioning unit main body 114 at a position slightly closer to the center in the vehicle width direction on the duct opening 118 side in the foot space E1. At that time, the attachment portions 126 and 128 in FIG. 2B are connected to attached portions (not shown) on the vehicle rear side and the vehicle front side of the air conditioning unit main body 114, respectively.

  As shown in FIG. 2B, the cover member 120 has at least a wall surface portion 130 on the vehicle rear side, a bottom surface portion 132 on the lower side, and a side surface portion 134 on the outer side in the vehicle width direction, with the base portion 122 as a main part. It has wall surfaces in three directions. The cover member 120 uses these wall surfaces to protect the air conditioning unit main body 114 from a passenger's kicking-up or the like.

  FIG. 3 is a cross-sectional view of the vehicle air conditioning structure 100 of FIG. FIG. 3A is a cross-sectional view taken along the line AA of the vehicle air conditioning structure 100 of FIG. 1B, and shows the air conditioning unit main body 114, the cover member 120, and the like with the dash panel 108 omitted.

  The wall surface portion 130 on the vehicle rear side of the cover member 120 is formed so as to be inclined toward the vehicle front side toward the vehicle lower side. Since the wall surface portion 130 has this shape, the cover member 120 avoids excessive interference with the occupant's toes. Therefore, the cover member 120 reduces the influence on the occupant's comfortability in the foot space E1, while protecting the air conditioning unit main body 114.

  FIG. 3B shows the virtual leg portion 10 when the dash panel 108, the occupant leg portion 136, and the cover member 120 as a conventional example are not provided in addition to the vehicle air conditioning structure 100 of FIG. Is shown.

  The instrument panel 104 protrudes from the dash panel 108 to the vehicle rear side, and is open above the foot space E1. Conventionally, as exemplified as the leg portion 10, the air conditioning unit main body 114 may be kicked up by an occupant. In this embodiment, by providing the cover member 120, it is possible to protect the air conditioning unit main body 114 from being kicked up by an occupant.

  The cover member 120 is set such that a predetermined distance C1 is provided between the bottom surface portion 132 of the base portion 122 and the floor 110. Since the interval C1 can be formed between the bottom surface portion 132 and the floor 110, workability such as a carpet (not shown) mounting operation can be ensured.

  In the present embodiment, the cover member 120 can keep the distance between the leg 136 and the duct opening 118. For this purpose, as shown in FIG. 1B, the cover member 120 is attached to the air conditioning unit main body 114 on the side of the duct opening 118 in the vehicle width direction in the foot space E1.

  As shown in FIG. 3B, the base 122 of the cover member 120 protrudes from the duct opening 118 to the vehicle lower side by a distance D1 at a position on the vehicle front side than the duct opening 118. Since the base 122 protrudes below the duct opening 118 from the duct opening 118, the movement range is restricted so that the occupant's leg 136 in the foot space E1 does not approach the duct opening 118.

  Specifically, in the foot space E1, the vicinity of the toe 138 interferes with the base 122, so that the shin 140 and the like cannot be raised to the height of the duct opening 118. That is, the occupant's leg 136 cannot be positioned directly beside the duct opening 118 in the vehicle width direction. By these, it is avoided that the warm air from the duct opening 118 continues to hit the shin 140 or the like directly.

  As described above, since the movement range of the occupant's leg 136 is restricted by the cover member 120, the leg 136 is prevented from coming too close to the duct opening 118. Thus, by ensuring the distance between the leg 136 and the duct opening 118, it is possible to efficiently avoid an unpleasant state for the occupant, such as hot air continuously hitting a specific portion of the leg 136. Is possible.

  FIG. 4 is a view showing the vehicle air conditioning structure 100 of FIG. FIG. 4A is a diagram showing the vehicle air conditioning structure 100 of FIG. 2A as viewed from the rear of the vehicle. In this embodiment, each part of the air conditioning unit main body 114 can be efficiently protected by the cover member 120.

  The connection connector 142 is a part that is electrically connected to predetermined electrical components (such as a register, a fan driver, and a thermistor connector) disposed near the feet of the front seat. The connection connector 142 is provided above the cover member 120 of the air conditioning unit main body 114 (upper side in FIG. 4A). Since the cover member 120 interferes with the occupant's leg 136 (see FIG. 3B), the leg 136 cannot reach above the cover member 120. Therefore, the connection connector 142 provided above the cover member 120 is also prevented from contacting the leg 136. Thus, the connection connector 142 is also efficiently protected from the contact of the leg 136 by the cover member 120.

  FIG. 4B is a diagram showing the vehicle air conditioning structure 100 of FIG. 3A as viewed from the front of the vehicle. A drain connector 144 for discharging drain (condensed water) is provided on the vehicle front side of the air conditioning unit main body 114, that is, on the dash panel 108 side. A drain hose 146 is connected to the drain connector 144 as shown in FIG.

  As shown in FIG. 3B, the drain hose 146 is provided by connecting the air conditioning unit main body 114 and the outlet (not shown) of the dash panel 108. The drain hose 146 is disposed in front of the cover member 120 and closer to the center of the vehicle in the vehicle width direction.

  As described above, the movement range of the occupant's leg 136 is restricted by the cover member 120, and the leg 136 cannot move to the front side of the vehicle relative to the cover member 120. Therefore, the leg member 136 can be prevented from being caught by the drain hose 146 by the cover member 120. In addition, it is not necessary to arrange the drain hose 146 so that the leg 136 does not touch it, and the degree of freedom in design is improved.

  For example, conventionally, the drain hose 146 may be disposed so as to pass between the dash panel 108 and a carpet (not shown) laid thereon. In this case, since the foot is placed on the carpet, the drain hose 146 is also weighted, and there is a concern that the drain hose 146 may be deformed in a direction to be crushed. In order to avoid such a situation, conventionally, the drain hose 146 has been adapted to be laid out toward the front side of the center console 112, but it is necessary to take such a layout. It also leads to a loss of design freedom. However, in the present embodiment, the cover member 120 prevents the drain hose 146 and the leg 136 from interfering with each other. Therefore, it is not necessary to devise the layout of the drain hose 146, and the degree of design freedom is maintained as compared with the conventional case. It is possible.

  As described above, according to the present embodiment, the cover member 120 can not only maintain an appropriate distance between the leg 136 and the duct opening 118, but also the air conditioning unit main body 114, the connection connector, and the like. 142 and the drain hose 146 can be protected by the integral cover member 120. Therefore, it is not necessary to provide individual protective members or the like on the connection connector 142, the drain hose 146, etc., the number of parts can be reduced, and the configuration can be simplified and the cost can be reduced.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.
