Description

  The present invention relates to an air-conditioning register that is arranged on, for example, an instrument panel in a vehicle cabin and supplies air-conditioning air.

  FIG. 9 is a side see-through view of the vehicle air-conditioning register described in Patent Document 1. The air conditioning register 100 includes a retainer 101, a lateral fin 102, and an eccentric link member 105. The retainer 101 includes a blower outlet 103 that is curved in the vertical direction. The air outlet 103 is exposed to the vehicle interior 104. The eight horizontal fins 102 are arranged in a line in the vertical direction along the outlet 103 inside the retainer 101. As shown in the figure, in the blowout port fully closed position, the eight lateral fins 102 cooperate to cover the entire surface of the blowout port 103. Each horizontal fin 102 includes a swing shaft and a driven point. The driven points of the horizontal fins 102 are connected to each other by an eccentric link member 105 accommodated inside the retainer 101. The eccentric link member 105 has a central axis A and an eccentric axis A ′.

FIG. 10 shows a schematic link diagram of the eccentric link member, the uppermost horizontal fin, and the lowermost horizontal fin at the outlet fully closed position. In the figure, the solid line indicates the position before swinging (the outlet fully closed position), and the alternate long and short dash line indicates the position after swinging. During the lateral fin operation, the driving force is transmitted from the eccentric link member 105 to each lateral fin 102. The eccentric shaft A ′ of the eccentric link member 105 is eccentrically oscillated around the central axis A in the counterclockwise direction as indicated by the white arrow in the figure. This driving force is transmitted to the driven point B ′ of the uppermost horizontal fin 102. The driven point B ′ oscillates around the oscillating axis B counterclockwise as indicated by the white arrow in the figure. Similarly, the driving force is transmitted to the driven point C ′ of the lowermost horizontal fin 102. The driven point C ′ oscillates around the oscillating axis C counterclockwise as indicated by the white arrow in the figure.

  By the way, in order to oscillate each lateral fin 102, it is necessary to apply a driving force to the driven point of each lateral fin 102 in the tangential direction of a circle around the oscillation axis. However, at the outlet fully closed position, the straight line B-B 'and the straight line C-C' are not parallel to the straight line A-A '.

  For this reason, according to the air-conditioning register 100 described in this document, all components of the driving force do not act in the tangential direction on the driven points B ′ and C ′. As an example, FIG. 11 shows a schematic view of the link between the eccentric link member and the lowermost horizontal fin at the outlet fully closed position. In the figure, the solid line indicates the position before swinging (the outlet fully closed position), and the alternate long and short dash line indicates the position after swinging. As shown in the figure, the driving force F is transmitted to the driven point C 'after being decomposed into a tangential component force F1 and a radial component force F2.

  With respect to the straight fin A2, the radial component force F2 increases as the horizontal fin 102 in which the straight line connecting the swing axis and the driven point is closer to the vertical. And the lateral fin 102 becomes difficult to rock | fluctuate, so that radial direction component force F2 is large. That is, in the case of the air-conditioning register 100 described in the same document, the horizontal fins 102 arranged below are less likely to swing. For this reason, according to the air-conditioning register 100 described in the same document, the swing resistance of the lateral fin 102 disposed below is large in the vicinity of the blowout port fully closed position. Therefore, the air outlet 103 of the air-conditioning register 100 described in the document is difficult to open and close near the air outlet fully closed position.

  In addition, in FIG. 10, the included angle α between the straight line A′-B ′ and the straight line A′-C ′ is fixed by the eccentric link member 105. Therefore, when the position of the eccentric shaft A ′ and the position of the driven point B ′ are fixed, the position of the driven point C ′ is also fixed by the position of the eccentric shaft A ′ and the position of the driven point B ′. Here, the position of the driven point C ′ when the horizontal fin swings does not exist on the circular orbit of the driven point C ′ centered on the swing axis C. FIG. 12 shows an enlarged view in a circle D of FIG. As shown in the figure, the driven point C ′ swings while approaching the swinging axis C from a position on the circular orbit of the driven point C ′ indicated by a white circle in the drawing. In order to absorb the tangent modernity of the driven point C ′, a long hole 106 is formed in the driven point C ′ connecting portion of the eccentric link member 105 described in the document.

  The air-conditioning register of the present invention has been completed in view of the above problems. Therefore, an object of the present invention is to provide an air-conditioning register having a small fin swing resistance and a simple structure.

(1) In order to solve the above-described problem, an air conditioning register according to the present invention has an eccentric shaft arranged eccentrically with respect to a central axis, and an eccentric link member that eccentrically swings about the central axis, and the eccentricity A plurality of fins each having a driven point to which a driving force from the link member is transmitted, and a swing shaft serving as a swing center when the driven point swings, and a curved outlet opening in the room And a cylindrical retainer in which a plurality of fins are arranged along the air outlets, wherein the plurality of fins cooperate in the air outlet fully closed position. The center axis, the eccentric shaft, the driven point, and the swing shaft are arranged so as to form a substantially parallelogram, and the eccentric link member is centered on the central axis. When eccentrically swung, each driven point of the plurality of fins from the eccentric link member The driving force is transmitted, and each driven point of the plurality of fins is arranged such that all components of the driving force transmitted from the eccentric link member act in a tangential direction with respect to each driven point of the fin. All of the fins are arranged so as to swing in the same direction .

  (2) Preferably, the eccentric link member is disposed outside the retainer, the fin is a lateral fin, and the blowout port has a design surface shape of an instrument panel that is exposed in a vehicle interior. And a plurality of the lateral fins cooperate to cover the air outlet and are arranged along the design surface of the instrument panel at the air outlet fully closed position. Better to do.

  According to the air conditioning register of the present invention, all components of the driving force act only in the tangential direction of each fin. For this reason, the rocking resistance of the fin is small. Further, since the long hole 106 shown in FIG. 12 is unnecessary, the structure is simple.

  Further, according to the configuration of (2), the ventilation resistance of the air-conditioning air flowing inside the retainer is smaller than when the eccentric link member is disposed inside the retainer. Moreover, according to this structure, in the blower outlet fully closed position, the horizontal fin and the instrument panel which cover a blower outlet can be substantially equalized.

  Hereinafter, an embodiment will be described in which the air-conditioning register according to the present invention is arranged for the vehicle at the right end of the driver's seat of the instrument panel.

  The gear group 6 includes an operation dial 60, a large gear 61, a damper connecting piece 62, and a small gear 63. The operation dial 60 is made of resin and has a disk shape. The dial swing protrusion 600 of the operation dial 60 is pivotally supported by a bracket (not shown) juxtaposed on the left side of the retainer body 40 so as to be swingable. A part of the periphery of the operation dial 60 protrudes from the dial operation port 411 of the bezel 41 into the vehicle interior 7.

  The large gear 61 is made of resin and has a disk shape. The large gear 61 is engaged with the operation dial 60. The large gear swing protrusion 610 of the large gear 61 is inserted into the large gear swing hole 402 of the retainer body 40. A large gear protrusion 611 is formed on the periphery of the large gear 61. A continuous arc-shaped guide groove 612 is formed in the large gear protrusion 611.

  The small gear 63 is made of resin and has a disk shape with a smaller diameter than the large gear 61. The small gear 63 meshes with the large gear 61. The small gear swing protrusion 630 of the small gear 63 is inserted into the small gear swing hole 403 of the retainer body 40. The small gear swing protrusion 630 is included in the central axis of the present invention. A small gear protrusion 631 is formed on the periphery of the small gear 63. An eccentric hole 632 is formed in the small gear protrusion 631. The eccentric protrusion 22 of the eccentric link member 2 is inserted into the eccentric hole 632.

  The damper connecting piece 62 is made of resin and has a sandwiched fan-like plate shape. A guide pin 620 protrudes from the end of the damper connecting piece 62 in the vehicle interior direction. The guide pin 620 is inserted into the guide groove 612 of the large gear 61. In addition, a damper fixing hole 621 is formed in the damper connecting piece 62. The damper fixing hole 621 is arranged in series with the damper swinging hole 404 of the retainer body 40 in the vehicle width direction.

  The damper 5 includes a damper main body 50 and a seal portion 51. The damper main body 50 is made of resin and has a rectangular plate shape. Damper swinging protrusions 500 are provided so as to protrude from the left and right end edges of the damper main body 50, respectively. The right damper swing protrusion 500 is pivotally supported on the right wall of the retainer body 40 so as to be swingable. On the other hand, the left damper swing protrusion 500 is inserted into the damper swing hole 404 on the left wall of the retainer body 40.

The seal portion 51 is made of rubber and has a rectangular frame shape. The seal portion 51 is provided around the periphery of the damper main body 50.

  Next, the operation of the air conditioning register of this embodiment will be described. In FIG. 3, when the operation dial 60 is swung clockwise as indicated by a white arrow in the figure, the large gear 61 meshing with the operation dial 60 is as indicated by a white arrow in the figure. Swings counterclockwise. In the guide groove 612 of the large gear 61, the guide pin 620 of the damper connecting piece 62 is in sliding contact. Therefore, when the large gear 61 swings, the damper connecting piece 62 and the damper 5 swing clockwise as indicated by the white arrow in the figure while being regulated by the groove wall shape of the guide groove 612. By this swinging of the damper 5, air for air conditioning is introduced from the air conditioning duct into the retainer main body 40. The small gear 63 meshes with the large gear 61. For this reason, when the large gear 61 swings, the small gear 63 swings clockwise as indicated by the white arrow in the figure. The small gear 63 and the eccentric link member 2 are connected via the eccentric hole 632 and the eccentric protrusion 22. For this reason, when the small gear 63 swings, the eccentric link member 2 eccentrically swings clockwise. FIG. 4 is a schematic diagram showing the relationship between the small gear swing and the eccentric link member eccentric swing. In the figure, the solid line indicates the position before swinging (the outlet fully closed position), and the alternate long and short dash line indicates the position after swinging. As shown in the drawing, when the small gear 63 swings, the eccentric link member 2 swings eccentrically around the small gear swing protrusion 630 of the small gear 63. When the eccentric link member 2 swings eccentrically, the driven hole 20 of the eccentric link member 2 moves in a clockwise arcuate path as shown by the white arrow in the figure (in the figure, the uppermost position is shown). Only the driven hole 20 shows a trajectory). Returning to FIG. 3, the swing protrusion 300 a of the fin coupling piece 31 is disposed at the center of the track of the driven hole 20. A driven projection 310 is inserted into the driven hole 20. For this reason, when the driven hole 20 of the eccentric link member 2 moves along an arcuate path, the fin connecting piece 31 and the fin main body 30 (that is, the horizontal fin 3) swing as shown by the white arrow in the figure. It swings clockwise around the protrusion 300a.

  FIG. 5 shows a side transmission diagram of the air conditioning register of the present embodiment at the horizontal fin upward position. As shown in the figure, when the operation dial 60 is swung by a predetermined amount, the guide pin 620 of the damper connecting piece 62 relatively moves to the substantially continuous arc central portion in the guide groove 612 of the large gear 61. . At this time, the damper 5 is substantially horizontal in the retainer body 40. For this reason, the ventilation resistance of the air for air conditioning in the retainer main body 40 becomes the minimum. That is, the damper 5 is fully opened. The lateral fin 3 faces upward as viewed from the vehicle interior 7. For this reason, the air-conditioning air is blown out from the air outlet 410 toward the upper side of the vehicle interior 7. As indicated by the white arrow in the figure, when the operation dial 60 is further swung clockwise from this state, the large gear 61 is swung further counterclockwise. In addition, the small gear 63 swings further clockwise. For this reason, the lateral fin 3 further swings clockwise. On the other hand, the damper 5 does not swing. The reason is that the center of curvature of the arc portion 612a of the guide groove 612 and the center of swing of the large gear 61 coincide. That is, even if the large gear 61 swings, the guide pin 620 is not restricted by the arc portion 612a.

  FIG. 6 shows a lateral transmission diagram of the air-conditioning register of the present embodiment at the horizontal fin downward position. As shown in the figure, when the operation dial 60 is further swung by a predetermined amount, the guide pin 620 of the damper connecting piece 62 is relatively moved to the clockwise end in the arc portion 612a of the guide groove 612 of the large gear 61. Move on. At this time, the lateral fin 3 faces downward as viewed from the vehicle interior 7. For this reason, air for an air conditioning blows off from the blower outlet 410 toward the vehicle interior 7 lower direction.

  As described above, according to the air conditioning register of this embodiment, the damper 5 can be switched from fully closed to fully open by switching from the state of FIG. 3 to the state of FIG. Further, the angle of the horizontal fin 3, that is, the air-conditioning air blowing angle can be adjusted between the state of FIG. 5 and the state of FIG.

  Next, the effect of the air conditioning register of this embodiment will be described. FIG. 7 shows a schematic link diagram of the eccentric link member, the uppermost horizontal fin, and the lowermost horizontal fin at the outlet fully closed position. In the figure, the solid line indicates the position before swinging (the outlet fully closed position), and the alternate long and short dash line indicates the position after swinging. In addition, the code | symbol of the corresponding site | part in above-mentioned FIG. 10 is shown in parenthesis. As shown in the figure, the small gear swing protrusion 630 (A), the eccentric protrusion 22 (A ′), the driven protrusion 310 (B ′), and the swing protrusion 300 a (B) form a parallelogram. Has been placed. In addition, the small gear swing protrusion 630 (A), the eccentric protrusion 22 (A ′), the driven protrusion 310 (C ′), and the swing protrusion 300 a (C) are arranged to form a parallelogram. . The other horizontal fins 3 and the eccentric link members 2 are also arranged so as to form a parallelogram, like the illustrated uppermost and lowermost horizontal fins 3.

  According to the air-conditioning register 1 of the present embodiment, all components of the driving force can be applied in the tangential direction to the driven protrusions 310 of all the lateral fins 3. As an example, FIG. 8 shows a schematic view of the link between the eccentric link member and the lowermost horizontal fin at the outlet fully closed position. In the figure, the solid line indicates the position before swinging (the outlet fully closed position), and the alternate long and short dash line indicates the position after swinging. In addition, the code | symbol of the corresponding site | part in above-mentioned FIG. 11 is shown in parenthesis. As shown in the figure, the driving force F acts only on the driven protrusion 310 (C ′) in the tangential direction. For this reason, the rocking resistance of the lateral fin 3 is small. Further, the swinging trajectory of the driven protrusion 310 (C ′) draws an arc shape centering on the swinging protrusion 300 a (C). That is, the driven protrusion 310 (C ′) does not approach the swing protrusion 300 a (C) while swinging. For this reason, the long hole 106 etc. of above-mentioned FIG. 11 are unnecessary. Therefore, the structure is simple.

  Moreover, according to the air-conditioning register 1 of the present embodiment, the eccentric link member 2 is arranged outside the retainer 4. For this reason, compared with the case where the eccentric link member 2 is arrange | positioned inside the retainer 4, the ventilation resistance of the air for air conditioning which flows through the inside of the retainer 4 becomes small. Moreover, according to the air-conditioning register 1 of the present embodiment, the seven horizontal fins 3 covering the air outlet 410 and the instrument panel can be made uniform at the air outlet fully closed position. For this reason, the appearance from the vehicle interior 7 is good.

  The embodiments of the air-conditioning register according to the present invention have been described above. However, the embodiment is not particularly limited to the above embodiment. Various modifications and improvements that can be made by those skilled in the art are also possible.

  For example, in the above-described embodiment, the central shaft (small gear swinging projection) 630 and the eccentric shaft (eccentric projection) 22 are disposed at the back of the vehicle compartment relatively far away from the lateral fin 3. However, the central shaft 630 and the eccentric shaft 22 may be arranged at positions close to the lateral fins 3. It suffices if a substantially parallelogram can be formed by the central shaft 630, the eccentric shaft 22, the driven point (driven projection) 310, and the swing shaft (swing projection) 300a.

  In the above embodiment, the central shaft 630, the eccentric shaft 22, the driven point 310, and the swing shaft 300a are formed in a protruding shape, but may be formed in a hole shape or a concave shape, for example. What is necessary is just to achieve the function of each part.

  Moreover, in the said embodiment, although the retainer 4 was formed from two members called the retainer main body 40 and the bezel 41, the retainer 4 may be an integral thing. This reduces the number of parts.

  Further, the air-conditioning register of the present invention is not limited to the driver seat, and can be used for the passenger seat and the rear seat, for example. Further, the present invention is not limited to a vehicle, and can be used as an air conditioning register of a residential air conditioner, for example. In addition, the air-conditioning register of the present invention can be applied to a structure in which vertical fins are arranged along the air outlet.
