Description
- This application is related to and claims priority from Japanese Patent Applications No. 2000-255907 filed on Aug. 25, 2000 and No. 2001-121432 filed on Apr. 19, 2001, the contents of which are hereby incorporated by reference.
- 1. Field of the Invention
- The present invention relates to an attachment structure of a door for adjusting an air flow. The present invention is suitably used for a vehicle air conditioner.
- 2. Description of Related Art
- In a conventional door attachment structure for a vehicle air conditioner, a shaft is integrated with a flat door, and an end of the shaft is rotatably supported in an attachment hole of a case defining an air passage, so that the air passage is opened and closed by the flat door. Further, plural ribs (generally three), each of which has a triangle cross-section, are formed on an inner wall surface defining the attachment hole to protrude inside, and an outer surface of the door shaft is partially supported by the plural ribs. That is, for reducing the driving force of the door, a contact area between the outer surface of the door shaft and the inner wall surface defining the attachment hole is reduced.
- However, for example, when the number of the ribs each having the triangle cross-section is three, the supporting area for supporting the outer surface of the door shaft is small. Therefore, the door shaft may tilt over when being into the attachment hole, and door attachment performance is deteriorated. On the other hand, if the number of the ribs is simply increased, a driving force for driving the door is increased.
- In view of the foregoing problems, it is an object of the present invention to provide a door attachment structure which improves door attachment performance while door driving force is restricted from being increased.
- According to the present invention, in a door attachment structure, a plurality of first ribs are provided on a part of an inner wall surface defining an attachment hole, in an axial direction of the attachment hole, to protrude to an outer surface of an insertion portion of the shaft inserted into the attachment hole; and a plurality of second ribs are provided on at least a part portion among the other part of the inner wall surface in the axial direction to protrude to the outer surface of the insertion portion of the shaft. In this attachment structure, the first ribs and the second ribs are positioned to be shifted from each other in a circumferential direction of the attachment hole. Therefore, the insertion portion of the shaft can be supported at points with the summation number of the first and second ribs. Furthermore, since the first and second ribs are shifted from each other in the axial direction, it can accurately prevent the shaft from being tilted in the attachment hole when the door is attached to the case. Therefore, the shaft can be smoothly inserted into the attachment hole, thereby improving attachment performance of the door.
- Further, because the first ribs and the second ribs are formed to be separated from each other in the axial direction, each axial length of the first and second ribs is smaller than an entire axial length of the attachment hole. Therefore, when the door is operated, the contact area between the inner wall surface defining the attachment hole and the outer surface of the shaft can be restricted from being increased, and the driving force of the door can be reduced.
- Additional objects and advantages of the present invention will be more readily apparent from the following detailed description of a preferred embodiment when taken together with the accompanying drawings, in which:
- FIG. 1 is a schematic view for explaining an attachment method of a door to a case, according to a preferred embodiment of the present invention;

Theshaft 4 is provided with arecess portion 5 at one end thereof, and a shaft portion of a link member (not shown) for driving thedoor 3 is connected into therecess portion 5 by press-fitting or the like. The other end of theshaft 4 has a protrusion protruding from the end of thedoor 3, and the protrusion has asmall diameter portion 4 a at a tip side thereof and alarge diameter portion 4 b connected to thesmall diameter portion 4 a. - On the other hand, the
case 1 is provided with acylindrical portion 6 protruding to both inner and outer sides of a wall of thecase 1, and thecylindrical portion 6 is provided with anattachment hole 7 into which the protrusion (small diameter portion 4 a andlarge diameter portion 4 b) of theshaft 4 is press-fitted. - As shown in FIG. 2, an inner wall surface of the
cylindrical portion 6 defining theattachment hole 7 has a small-diameterinner surface 7 a at one end in an axial direction, andfirst ribs 8 are provided to protrude from the small-diameterinner surface 7 a to radial inner sides. That is, thefirst ribs 8 protrude toward the outer surface of thesmall diameter portion 4 a of theshaft 4 inserted into theattachment hole 7.

That is, thesecond ribs 9 protrude to the outer surface of thelarge diameter portion 4 b of theshaft 4 when theshaft 4 is inserted into theattachment hole 7. - As shown in FIG. 2, each of the first and
second ribs first ribs 8 and the threesecond ribs 9 are arranged to be offset from each other in a circumferential direction of theattachment hole 7. More specifically, the threefirst ribs 8 are arranged at intervals of 120 degrees, and the threesecond ribs 9 are also arranged at intervals of 120 degrees. In addition, eachfirst rib 8 is arranged at a middle position between adjacentsecond ribs 9 in the circumferential direction, and eachsecond rib 9 is also arranged at a middle position between adjacentfirst ribs 8 in the circumferential direction. Thesecond ribs 9 are formed on the large-diameterinner surface 7 b along an entire length in an axial direction thereof, as shown in FIGS. 3A and 3B. - As shown in FIGS. 3A and 3B, an inner radial dimension D1 at the tips of the
first ribs 8 is smaller than an inner radial dimension D2 at the tips of thesecond ribs 9. The inner radial dimension D1 is set slightly smaller than an outer diameter of thesmall diameter portion 4 a, and the inner radial dimension D2 is set slightly smaller than an outer diameter of thelarge diameter portion 4 b. Further, a protrusion height of the first andsecond ribs tapered guide portion 7 c for guiding an insertion of theshaft 4 is provided in thecylindrical portion 6 at an inlet side of theattachment hole 7. - Next, an attachment method of the
door 3 to thecase 1 will be now described with reference to FIG. 1. The protrusion (i.e.,small diameter portion 4 a andlarge diameter portion 4 b) of theshaft 4 is inserted into theattachment hole 7 of thecylindrical portion 6 of thecase 1 in a direction indicated by an arrow A in FIG. 1. Since the threefirst ribs 8 and the threesecond ribs 9 are arranged to be shifted (offset) from each other in the circumferential direction, theshaft 4 inserted into theattachment hole 7 is supported substantially at six points in the circumferential direction. Further, since eachfirst rib 8 and eachsecond rib 9 are also shifted from each other in the axial direction of theattachment hole 7, it can accurately prevent theshaft 4 from being inclined. - As a result, the
door 3 can be prevented from being inclined in a direction indicated by an arrow B in FIG. 1 when thedoor 3 is assembled to thecase 1, and the protrusion of theshaft 4 can be smoothly inserted into theattachment hole 7, thereby improving the attachment performance of thedoor 3. - Further, when the
shaft 4 is inserted into theattachment hole 7, thesmall diameter portion 4 a positioned at a tip side of theshaft 4 can be firstly inserted within thefirst ribs 8, and then thelarge diameter portion 4 b can be inserted within thesecond ribs 9. Accordingly, thesmall diameter portion 4 a and thelarge diameter portion 4 b are not inserted within the first andsecond ribs shaft 4 can be inserted into theattachment hole 7 by a smaller insertion force, thereby furthermore improving the attachment performance of thedoor 4. - The shaft portion (not shown) of the link member for driving the
door 3 is integrally inserted into therecess portion 5 of theshaft 4 through an attachment hole (not shown) of thecase 1 by press-fitting or the like. - The
first ribs 8 and thesecond ribs 9 are provided to be separated from each other in the axial direction of theattachment hole 7, respectively. Further, each axial length of thefirst ribs 8 and each axial length of thesecond ribs 9 are small and correspond to a part of an entire axial length of theattachment hole 7. Therefore, when the air conditioner is operated, a contact friction area between the inner wall surface of thecylindrical portion 6 defining theattachment hole 7 and the outer surfaces of thesmall diameter portion 4 a and thelarge diameter 4 b of theshaft 4 can be restricted from being increased, and the driving force of thedoor 3 can be restricted from being increased. - The
shaft 4 is formed into a step shape including the tip-sidesmall diameter portion 4 a and thelarge diameter portion 4 b connected to thesmall diameter portion 4 a. Further, the inner radial dimension D2 of the tips of thesecond ribs 9, corresponding to the outer diameter of thelarge diameter portion 4 b, is made larger than the inner radial dimension D1 of the tips of thefirst ribs 8, corresponding to the outer diameter of thesmall diameter portion 4 a. Therefore, a mold die for molding thecase 1 can be readily removed from thecase 1 in the left direction in FIGS. 3A and 3B, after thecase 1 is molded. - FIG. 4 is a schematic view showing the vehicle air conditioner. As shown in FIG. 4, the vehicle air conditioner includes an inside/outside switching
door 10 for selectively opening and closing an air introduction port from which air is introduced, anair mixing door 11 for adjusting temperature of blown air, and mode switching doors (i.e., facedoor 12,defroster door 13 and foot door 14). The attachment structure of thedoor 3 described above can be used for any one of the doors 10-14. - Although the present invention has been fully described in connection with the preferred embodiment thereof with reference to the accompanying drawings, it is to be noted that various changes and modifications will become apparent to those skilled in the art.
- For example, the number of the
first ribs 8 and the number of thesecond ribs 9 may be two or more than three without being limited to three. - In the above-described embodiment, the protrusion of the
shaft 4 to be inserted into theattachment hole 7 can be formed so that the outer diameter of thesmall diameter portion 4 a is equal to that of thelarge diameter portion 4 b. In this case, the inner radial dimension D1 of the tips of thefirst ribs 8 is made equal to the inner radial dimension D2 of the tips of thesecond ribs 9. Even in this case, because thefirst ribs 8 and thesecond ribs 9 are separated from each other in the axial direction, the door assembling performance can be improved. - Such changes and modifications are to be understood as being within the scope of the present invention as defined by the appended claims.
