Description

  The present invention relates to an air conditioner including a main body that adjusts the temperature of air, and a duct that is connected to the main body and includes a support that supports an instrument panel.

  The vehicle instrument panel has both ends in the vehicle width direction fixed to the pillars of the vehicle body, and its rear end is fixed to the deck cross member passed between the pillars on both sides in the vehicle width direction via brackets. The part is fixed to the outlet of the front defroster duct of the air conditioner arranged inside the instrument panel.

  However, in this type of instrument panel support structure, the central portion along the front-rear direction of the instrument panel is not supported anywhere. As a result, it is conceivable that the rigidity of the substantially central portion along the front-rear direction in the instrument panel decreases.

In an automobile equipped with this type of air conditioner, it has been proposed to improve the rigidity of the central portion of the instrument panel using a front defroster duct. Specifically, a support part is provided in the front defroster duct, and this support part supports the substantially center part in the front-rear direction of the instrument panel (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 2004-203244

  However, the front defroster duct is generally disposed at a substantially central portion in the vehicle width direction, and the length along the vehicle width direction is not so long as to cover the entire area along the vehicle width direction of the instrument panel.

  Therefore, since the range between the defroster duct and the pillar is not supported anywhere in the instrument panel, its stiffness remains low.

  Accordingly, an object of the present invention is to provide an air conditioner that can effectively improve the support rigidity of an instrument panel.

The air conditioner of the present invention includes a main body, a duct, a support, and a side defroster duct member . The main body adjusts the air supplied into the vehicle. The duct part has a front defroster duct part and an intake duct part. The front defroster duct part is connected to the main body part and guides the air adjusted by the main body part to the windshield.

The said duct part is arrange | positioned inside an instrument panel. The said support part is formed in the site | part which faces the said instrument panel in the said duct part, and supports the said instrument panel. The side defroster duct member guides the air adjusted by the main body to the side window glass. At least a part of the support part is formed in the intake duct part to support and guide the side defroster duct member.

According to this structure, the duct portion is elongated in the vehicle width direction by arranging the front defroster duct portion and the intake duct portion side by side in the vehicle width direction. Therefore, the range in which the support portion can be formed is expanded. In other words, the range that can be supported by the support portion in the instrument panel is widened. Moreover, according to this structure, it is not necessary to form a member or a part for guiding the side defroster duct member.

  In a preferred embodiment of the present invention, the duct portion has a length that substantially reaches the length of the instrument panel in the vehicle width direction.

  According to this structure, the length of the duct portion can be further increased.

  According to the present invention, it is possible to effectively improve the support rigidity of the instrument panel.

A plurality of screw holes 71 are formed in the second support portion 62. The screw holes 71 are arranged in the vehicle width direction. As shown in FIG. 1, the second support portion 62 also functions as a support portion that guides the side defroster duct member 43. A plurality of reinforcing ribs 62 a are formed on the second support portion 62.

  The third and fourth support portions 63 and 64 will be specifically described. As shown in FIG. 3, a recessed portion 66 that guides the side defroster duct member 43 is formed on the opposite side of the intake duct forming portion 45 a across the front defroster duct forming portion 45 b in the main body member 45. The recessed portion 66 is formed in a curved shape so that the side defroster duct member 43 is recessed toward the rear of the vehicle body. A part of the side defroster duct member 43 is accommodated in the recess 66.

  Therefore, the edge of the recess 66 protrudes relatively upward with respect to the bottom surface 66 a of the recess 66. A part of the edge portion toward the rear of the vehicle body is a third protrusion 63. The third protrusion 63 is, for example, long in the vehicle width direction, and a plurality of screw holes 71 are formed. These screw holes 71 are arranged in the vehicle width direction.

  Of the edge portion of the recessed portion 66, a portion facing the front pillar 24 is a fourth support portion 64. The fourth support portion 64 has a shape that is long in the vehicle width direction, for example. A plurality of screw holes 71 are formed in the fourth support portion 64. These screw holes 71 are arranged in the vehicle width direction.

  The 5th support part 65 is demonstrated concretely. An end of the main body member 45 on the intake duct forming portion 45 a side is formed corresponding to the shape of the dash panel 23. As shown in FIG. 2, the end of the dash panel 23 on the intake duct forming portion 45a side is stepped in the vertical direction. Therefore, the end on the intake duct forming portion 45a side of the main body member 45 is also formed in a step shape. A portion of the stepped portion that protrudes toward the passenger compartment is a fifth support portion 65. The fifth support portion 65 has, for example, a shape that is long in the vehicle width direction, and a plurality of screw holes 71 are formed. These screw holes 71 are arranged in the vehicle width direction.

  As shown in the above and the drawings, the first to fifth support portions 61 to 65 are arranged so as to cover substantially the entire region of the main body member 45 in the vehicle width direction.

  Next, a fixing structure between the duct portion 42 and the dash panel 23 will be described. As shown in FIG. 2, a second through hole 73 through which the bolt 72 passes is formed at a portion of the main body member 45 where the intake duct forming portion 45 a and the front defroster duct forming portion 45 b are avoided.

  The second through hole 73 will be described in detail. The end portions of the main body member 45 on the third and fourth support portions 63 and 64 side are formed in a step shape in the vertical direction. A second plane 75. The second plane 75 is a plane located above the first plane 74. Accordingly, a third plane 76 that receives the first plane 74 is formed at a portion of the dash panel 23 that faces the first and second planes 74 and 75.

  The second through hole 73 is formed in the first plane 74. A third through hole 78 through which the bolt 72 passes is formed at a portion facing the second through hole 73 in the third plane 76 of the dash panel 23.

  Further, the end portion on the fifth support portion 65 side of the main body member 45 is formed in a step shape as described above. Therefore, fourth and fifth flat surfaces 80 and 81 are formed at the end of the main body member 45 on the fifth support portion 65 side. The fifth plane 81 is a plane located above the fourth plane 80. Along with this, on the portion facing the fourth and fifth planes 80 and 81 in the dash panel 23, sixth and seventh planes 82 and 83 for receiving the fourth and fifth planes 80 and 81 are formed. The second through hole 73 is formed in the fifth plane 81. A third through hole 78 is formed at a portion of the sixth plane 82 of the dash panel 23 that faces the second through hole 73.

  The second through holes 73 are formed one on each side of the front defroster duct forming portion 45b. In the dash panel 23 that is not accompanied by this, there is a second through hole 73 at a portion corresponding to both sides of the front defroster duct forming portion 45b. Three through holes 78 are formed.

  The duct portion 42 is fixed to the dash panel 23 by the bolt 72 passing through the first and second through holes 73 and 78 and screwing into a nut (not shown).

  Next, a fixing structure between the instrument panel 30 and the duct portion 42 will be described. As shown in FIG. 5, a projecting portion 33 projecting toward the first to fifth support portions 61 to 65 is formed at the center portion in the front-rear direction of the instrument panel 30. In the instrument panel 30, the protrusions 33 corresponding to the first to fifth support portions 61 to 65 may have substantially the same structure, and thus represent the protrusion 33 corresponding to the first support portion 61. I will explain.

  The protrusion 33 extends until the instrument panel 30 contacts the first support 61 when the instrument panel 30 is attached to the vehicle body 20. The protrusion 33 is provided with a seat 34 that contacts the first support 61 and receives the screw 70. The seat 34 is formed with a fourth through hole 35 through which the screw 70 passes.

  Even if it is the protrusion part corresponding to the 2nd-5th support parts 62-65 in the instrument panel 30, it is the same as that of the protrusion part 33. FIG. In addition, the protrusion part 33 corresponding to the 2nd-5th support parts 62-65 is extended until it contact | abuts to a corresponding support part.

  When the instrument panel 30 is stacked above the duct portion 42, the seat 34 of each projecting portion 33 comes into contact with the first to fifth support portions 61 to 65. The screw 70 is screwed into the screw hole 71 through the fourth through hole 35. Further, the peripheral edge portion 49b of the first opening 49a of the front defroster duct portion 49 extends toward the instrument panel 30, and the second opening portion 31 of the instrument panel 30 is connected to the first opening portion 49a. It protrudes toward the duct portion 42 so as to fit inside the peripheral edge portion 49b. The 2nd opening part 31 fits in the 1st opening part 49a peripheral part 49b.

  Thus, the instrument panel 30 is fixed to the dash panel 23 by fastening with the screw 70 and fitting the second opening 31 into the first opening 49a peripheral edge 49b. Further, the rear end portion of the deck cross member 25 in the instrument panel 30 is supported by the deck cross member 25 by a bracket (not shown). An interference member 37 is interposed between the front end portion 36 of the instrument panel 30 and the front window glass 29. Similarly, an interference member 37 is interposed between the front end portion 36 and the dash panel 23. That is, the front end portion 36 of the instrument panel 30 is supported between the front window glass 29 and the dash panel 23 via the interference member 37.

  In the air conditioner 40 configured as described above, the main body member 45 includes a front defroster duct forming portion 45b and an intake duct forming portion 45a. The front defroster duct forming portion 45b and the intake duct forming portion 45a are arranged side by side in the vehicle width direction, so that the main body member 45 becomes longer in the vehicle width direction.

  When the main body member 45 becomes longer in the vehicle width direction, a range in which the support portion that supports the instrument panel 30 in the main body member 45 can be arranged is increased. In other words, since the range supported by the main body member 45 at the center portion in the front-rear direction of the instrument panel 30 is increased, the support rigidity of the instrument panel 30 is effectively improved.

  In addition, since the main body member 45 has a length from the one front pillar 24 to the other front pillar 24, the range supported by the duct portion 42 in the instrument panel 30 is further widened. The support rigidity of 30 is improved more effectively.

  Moreover, since the 1st-5th support parts 61-65 are formed so that the vehicle width direction substantially whole region may be covered, the support rigidity of the instrument panel 30 improves further.

  Furthermore, since the main body member 45 has a length that reaches from the one front pillar 24 to the other front pillar 24, the main body member 45 effectively functions as a soundproof material.

  Furthermore, since the area of the main body member 45 is large, the degree of freedom in supporting various harnesses is improved. This point will be specifically described. As shown in FIG. 1, for example, when the harness 100 of the antenna 101 of the car navigation system is fixed to the vehicle body, the harness 100 can be fixed at an arbitrary position of the main body member 45. That is, the main body member 45 functions as a fixing portion for fixing the harness 100, and the harness 100 is not complicatedly handled by the main body member 45 being long in the vehicle width direction.

  Furthermore, since the main body member 45 is made of resin, an attachment hole for fixing, for example, the clip 200 used when fixing the harness 100 can be easily formed in the main body member 45. That is, the harness 100 can be easily fixed to the main body member 45.

  The second and third support portions 62 and 63 also have a function of supporting the posture of the side defroster duct member 43 and guiding the side defroster duct member 43. As described above, the support portion has a function of supporting the attitude of the side defroster duct member 43 and guiding the side defroster duct member 43, thereby separately supporting the side defroster duct member 43 and guiding the side defroster duct member 43. It is not necessary to form a member or part to be used.
