Description

[Technical Field]

[0001] The present invention relates to an air conditioning register. [Background technology]

[0002] BACKGROUND ART Automobiles are provided with air conditioning registers that blow air for air conditioning into the vehicle interior (see, for example, Patent Document 1). The airflow direction adjusting device described in Patent Document 1 includes a cylindrical case body, and a plurality of intermediate movable fins and a plurality of rear fins provided inside the case body.

[0003] The plurality of intermediate movable fins are provided at intervals from one another in the Y direction, which is the planar direction of the opening surface of the air outlet. The rear fins are provided on the opposite side of the intermediate movable fin from the air outlet.

[0004] The direction in which the intermediate movable fins and the air outlet are aligned is defined as the X direction, and the direction perpendicular to both the Y direction and the X direction is defined as the Z direction. The intermediate movable fin is supported so as to be rotatable about an axis extending in the Z direction. Rotation of the intermediate movable fin changes the wind direction of the air for air conditioning in the Y direction. A drive mechanism that rotationally drives the intermediate movable fin is provided on the outside of the case body in the Z direction.

[0005] The rear fin is supported so as to be rotatable about an axis extending in the Y direction. The rotation of the rear fin changes the wind direction of the air for air conditioning in the Z direction. A drive mechanism that drives the rotation of the rear fin is provided on the outside of the case body in the Y direction. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2022-150682 Summary of the Invention [Problem to be solved by the invention]

[0007] In the airflow direction adjusting device described in Patent Document 1, the drive mechanism that rotates the intermediate movable fin is provided on the outside of the case body in the Z direction, which makes it difficult to reduce the dimension of the air conditioning register in the Z direction, i.e., to make it thinner. [Means for solving the problem]

[0008] Various aspects of an air-conditioning register for solving the above problems will be described below. [Aspect 1] a retainer having a ventilation passage including an outlet for blowing out air for air conditioning; a downstream fin shaft disposed within the retainer; an upstream fin shaft provided in the retainer on the opposite side of the downstream fin shaft from the air outlet, The downstream fin shaft a downstream shaft configured to be rotatable about a first axis extending in a first direction, which is a plane direction of an opening surface of the air outlet; a downstream fin provided on an outer peripheral surface of the downstream shaft and inclined with respect to an imaginary plane perpendicular to the first axis, The upstream fin shaft an upstream shaft configured to be rotatable about a second axis extending in the first direction; an upstream fin extending in the first direction, a driving device that rotates and drives the downstream shaft and the upstream shaft is provided on one side of the downstream shaft and the upstream shaft in the first direction; Air conditioning register.

[0009] According to this configuration, the drive device that rotates the downstream shaft and the upstream shaft is provided on one side of the downstream shaft and the upstream shaft in the first direction. This prevents the size of the air-conditioning register in the third direction from increasing due to the drive device. This allows the air-conditioning register to be made thinner.

[0010] [Aspect 2] the drive device has a common drive gear that transmits rotational forces to the downstream shaft and the upstream shaft, respectively; 2. The air conditioning register according to claim 1.

[0011] This configuration allows the downstream and upstream shafts to be rotationally driven by a common drive gear, which allows the rotational displacement of the downstream fin shaft to be linked to the rotational displacement of the upstream fin shaft, thereby reducing the number of parts in the drive device.

[0012] [Aspect 3] a cutout portion, which is a portion on an outer circumferential surface of the downstream shaft where the downstream fin is not provided in a circumferential direction of the downstream shaft, A direction perpendicular to the first direction, a direction in which the downstream fin shaft and the air outlet are arranged, is defined as a second direction, and a direction perpendicular to both the first direction and the second direction is defined as a third direction. the ventilation passage has a first passage portion and a second passage portion located on one side and the other side of the downstream shaft in the third direction, respectively; The cutout portion is configured to be located in the first passage portion and the second passage portion when the downstream fin is located on one side or the other side of the downstream shaft in the second direction. The air-conditioning register according to aspect 1 or aspect 2.

[0013] According to this configuration, when the downstream fin is positioned in the first passage portion, the conditioned air flowing through the first passage portion flows along the downstream fin as it passes through the downstream fin, thereby changing the direction of the conditioned air blown out through the air outlet to one side of the first direction.

[0014] Furthermore, when the downstream fins are positioned in the second passage portion, the conditioning air flowing through the second passage portion flows along the downstream fins as it passes through them. Here, the inclination direction of the downstream fins when positioned in the second passage portion is opposite to the inclination direction of the downstream fins when positioned in the first passage portion. This changes the wind direction of the conditioning air blown out through the air outlet to the other side of the first direction.

[0015] Furthermore, according to the above configuration, the outer peripheral surface of the downstream shaft is provided with a missing portion where no downstream fins are provided in the circumferential direction of the downstream shaft. The missing portion is located in the first passage portion and the second passage portion when the downstream fins are located on one side or the other side of the downstream shaft in the second direction (hereinafter referred to as the neutral position of the downstream fin shaft). At this time, the air for conditioning is blown out from the outlet without being subject to a change in wind direction as it flows through the first passage portion and the second passage portion. Furthermore, when the downstream fin shaft is in the neutral position, no downstream fins are located in the first passage portion or the second passage portion, thereby suppressing an increase in pressure loss.

[0016] Therefore, it is possible to switch between a state in which the direction of the air-conditioning air blown out from the air outlet is changed and a state in which the direction of the air is not changed. [Aspect 4] When the downstream fin is a first downstream fin, a second downstream fin protruding from an outer peripheral surface of the downstream shaft on a portion opposite to the first downstream fin across the downstream shaft; The second downstream fin has an inclination direction with respect to the virtual plane that is the same as that of the first downstream fin. 4. The air-conditioning register according to claim 3.

[0017] According to this configuration, when the first downstream fin is located in the first passage portion, the second downstream fin is located in the second passage portion. Therefore, the air for conditioning flowing through the first passage portion flows along the first downstream fin when passing through the first downstream fin, and the air for conditioning flowing through the second passage portion flows along the second downstream fin when passing through the second downstream fin. Here, the second downstream fin has the same inclination direction with respect to the imaginary plane as the first downstream fin. This changes the wind direction of the air for conditioning air blown out through the air outlet to one side of the first direction.

[0018] Furthermore, when the second downstream fin is located in the first passage portion, the first downstream fin is located in the second passage portion. Therefore, the air for conditioning flowing through the first passage portion flows along the second downstream fin when passing through the second downstream fin, and the air for conditioning flowing through the second passage portion flows along the first downstream fin when passing through the first downstream fin. Here, the inclination direction of the second downstream fin when located in the first passage portion is opposite to the inclination direction of the second downstream fin when located in the second passage portion. This changes the wind direction of the air for conditioning air blown out through the air outlet to the other side of the first direction.

[0019] Therefore, the air direction of the air-conditioning air flowing through the first passage portion or the air-conditioning air flowing through the second passage portion can be changed to either side of the first direction. [Aspect 5] The upstream fin is a first airflow direction control position that guides the flow of the air conditioning air to the first passage portion and restricts the air conditioning air from flowing to the second passage portion; a second airflow direction control position that guides the flow of the air conditioning air to the second passage portion and restricts the air conditioning air from flowing into the first passage portion; a neutral position in which the flow of the air conditioning air is guided to both the first passage portion and the second passage portion, The air-conditioning register according to aspect 3 or aspect 4.

[0020] According to this configuration, by displacing the upstream fin to any one of the first wind direction control position, the second wind direction control position, and the neutral position, it is possible to change the passage section through which the air for air conditioning flows, between the first passage section and the second passage section.

[0021] However, by providing the downstream fin shaft inside the retainer, there is a risk that the pressure loss will increase due to the air for air conditioning colliding with the downstream shaft. In this regard, with the above-described configuration, the upstream fin guides the flow of the air conditioning air to either or both of the first and second passages, thereby preventing the air conditioning air from colliding with the downstream shaft and thereby suppressing an increase in pressure loss.

[0022] [Aspect 6] the upstream fin has a first surface and a second surface extending in the first direction, The retainer is a housing portion that houses the downstream fin shaft and the upstream fin and has the air outlet; a connecting portion that is connected to the upstream side of the storage portion in the flow direction of the air-conditioning air, and in which a distance between a pair of inner walls that face each other in the third direction is smaller than that of the storage portion, In the first airflow direction control position, only the first surface extends obliquely with respect to the second direction so as to extend from the connection portion toward the first passage portion, In the second airflow direction control position, only the second surface extends obliquely with respect to the second direction so as to extend from the connection portion toward the second passage portion, In the neutral position, the second surface extends obliquely with respect to the second direction so as to be from the connection portion toward the first passage portion, and the first surface extends obliquely with respect to the second direction so as to be from the connection portion toward the second passage portion. 6. The air conditioning register according to claim 5.

[0023] According to this configuration, by rotating the upstream fin about an axis extending in the first direction, the upstream fin can be displaced to the first wind direction control position, the second wind direction control position, and the neutral position.

[0024] [Aspect 7] The upstream fin is configured to be displaceable to a blocking position to block the ventilation passage. The air conditioning register according to aspect 5 or 6.

[0025] According to this configuration, the upstream fin blocks the ventilation passage, thereby preventing the air for air conditioning from being blown out through the air outlet. [Effects of the Invention]

[0026] According to the present invention, it is possible to reduce the thickness of the air-conditioning register. [Brief explanation of the drawings]

In this embodiment, the vehicle width direction X, the front-rear direction Y, and the up-down direction Z correspond to the first direction X, the second direction Y, and the third direction Z, respectively.

[0030] Hereinafter, each component of the air-conditioning register of this embodiment will be described in detail. <Retainer 10> As shown in FIGS. 3 and 5, the retainer 10 has an air passage 17 including an outlet 18 through which air for air conditioning is blown out.

[0031] As shown in FIG. 5, the retainer 10 has a lower wall 11, an upper wall 12 located above the lower wall 11, a pair of side walls 13 located on both sides in the vehicle width direction X and connecting the lower wall 11 and the upper wall 12, and a bezel 16.

[0032] The retainer 10 has a housing portion 14 having an air outlet 18, and a connection portion 15 connected to the housing portion 14 on the upstream side in the flow direction of the air for air conditioning. The housing portion 14 houses a downstream fin shaft 20 and upstream fins 32, which will be described later.

[0033] In the connecting portion 15, the distance between the lower wall 11 and the upper wall 12 is smaller than that in the storage portion 14. That is, in the connecting portion 15, the distance between a pair of inner walls facing each other in the third direction Z is smaller than that in the storage portion 14.

[0035] 5, the air outlet 18 is located on an imaginary line L that passes through the center of the connection portion 15 in the vertical direction Z and extends along the front-to-rear direction Y. The width of the air outlet 18 in the vertical direction Z is smaller than the width of the connection portion 15 in the vertical direction Z.

[0036] The lower wall 11 and the upper wall 12 that constitute the connection portion 15 extend along the front-rear direction Y. The lower wall 11 constituting the storage section 14 is curved so as to be positioned higher as it approaches the air outlet 18.

[0037] <Downstream Fin Shaft 20> As shown in FIGS. 1 to 3 and 5, downstream fin shaft 20 is provided in housing portion 14 of retainer 10. As shown in FIGS.

[0038] As shown in FIGS. 2(a) to 2(c), the downstream fin shaft 20 includes a downstream shaft 21, a first downstream fin 25, and a second downstream fin . As shown in FIG. 5, the downstream shaft 21 is configured to be rotatable about a first axis C1 extending in the vehicle width direction X.

[0039] As shown in FIGS. 1 to 3 and 5, the downstream shaft 21 has a cylindrical peripheral wall 22 extending in the first direction X. As shown in FIGS. 2(a) to 2(c), the first downstream fin 25 is provided to protrude from the outer peripheral surface of the downstream shaft 21 and is inclined with respect to an imaginary plane V that is perpendicular to the first axis C1.

[0040] The second downstream fin 26 is provided to protrude from the outer circumferential surface of the downstream shaft 21 on the opposite side of the downstream shaft 21 from the first downstream fin 25 . The second downstream fin 26 has the same inclination direction with respect to the imaginary plane V as the first downstream fin 25.

[0041] In this embodiment, the plurality of first downstream fins 25 and the plurality of second downstream fins 26 are provided at intervals from each other in the vehicle width direction X. The outer circumferential surface of the downstream shaft 21 is provided with a cutout portion 27, which is a portion where the first downstream fin 25 and the second downstream fin 26 are not provided in the circumferential direction of the downstream shaft 21. The cutout portion 27 is provided on both of the outer circumferential surface of the downstream shaft 21 between the first downstream fin 25 and the second downstream fin 26 in the circumferential direction of the downstream shaft 21.

[0042] As shown in FIG. 5, the ventilation passage 17 has a first passage portion 17A and a second passage portion 17B located above and below the downstream shaft 21, respectively. The cutout portions 27 are configured to be located in the first passage portion 17A and the second passage portion 17B when the first downstream fin 25 and the second downstream fin 26 are located in front or rear of the downstream shaft 21.

[0043] 1, 3, and 4, a downstream driven gear 28 is provided at one end of the downstream shaft 21. The downstream driven gear 28 is a spur gear. <Upstream Fin Shaft 30> 1, 3, and 5, the upstream fin shaft 30 is provided in front of the downstream fin shaft 20 within the retainer 10. In other words, the upstream fin shaft 30 is provided on the opposite side of the downstream fin shaft 20 from the air outlet 18 within the retainer 10.

[0044] As shown in FIG. 5, the upstream fin shaft 30 has an upstream shaft 31 having a second axis C2 extending in the first direction X, and upstream fins 32 configured to be rotatable about the second axis C2.

[0045] The upstream fin 32 has a first surface 34 and a second surface 36 extending in a first direction X. The upstream fin 32 has a flat plate-shaped first upstream fin 33 and a second upstream fin 35. The first upstream fin 33 and the second upstream fin 35 each protrude from the upstream shaft 31 in the radial direction of the upstream shaft 31. The angle between the first upstream fin 33 and the second upstream fin 35 is, for example, 60 degrees. Of the pair of main surfaces of the first upstream fin 33, the surface that is away from the second upstream fin 35 constitutes a first surface 34. Of the pair of main surfaces of the second upstream fin 35, the surface that is away from the first upstream fin 33 constitutes a second surface 36.

[0046] The upstream fins 32 are configured to be displaceable among a first wind direction control position, a second wind direction control position, a neutral position, and a blocking position. 7 and 9, the first airflow direction control position is a position where the upstream fins 32 guide the flow of air-conditioning air to the first passage portion 17A and restrict the air-conditioning air from flowing into the second passage portion 17B. In the first airflow direction control position, of the first surface 34 and the second surface 36, only the second surface 36 extends at an angle with respect to the second direction Y so as to be directed from the connection portion 15 toward the first passage portion 17A.

[0047] 11 , the second airflow direction control position is a position where the upstream fins 32 guide the flow of air-conditioning air to the second passage portion 17B and restrict the air-conditioning air from flowing into the first passage portion 17A. In the second airflow direction control position, of the first surface 34 and the second surface 36, only the first surface 34 extends at an angle with respect to the second direction Y so as to face from the connection portion 15 toward the second passage portion 17B.

[0048] 5, the neutral position is a position where the upstream fin 32 guides the flow of air conditioning air to both the first passage portion 17A and the second passage portion 17B. In the neutral position, the second surface 36 extends at an angle with respect to the second direction Y so as to extend from the connection portion 15 toward the first passage portion 17A, and the first surface 34 extends at an angle with respect to the second direction Y so as to extend from the connection portion 15 toward the second passage portion 17B.

[0049] As shown in FIG. 12, the blocking position is a position where the upstream fin 32 blocks the ventilation passage 17. As shown in FIGS. 1, 3, and 4, an upstream driven gear 38 is provided at one end of the upstream shaft 31.

[0050] 4, the upstream driven gear 38 has a plurality of slots 39 extending along the radial direction of the upstream driven gear 38. The plurality of slots 39 are provided at equal intervals in the circumferential direction of the upstream driven gear 38. In this embodiment, six slots 39 are provided at equal intervals (60-degree intervals) in the circumferential direction of the upstream driven gear 38.

The drive device 40 includes a motor 47 and a common drive gear 41 that is rotationally driven by the motor 47 to transmit rotational force to the downstream shaft 21 and the upstream shaft 31, respectively.

[0053] As shown in FIG. 5, the drive gear 41 is driven to rotate about a third axis C3 extending in the vehicle width direction X. The drive gear 41 has a downstream driving gear 42 that meshes with the downstream driven gear 28 to continuously rotate the downstream driven gear 28. The downstream driving gear 42 is a spur gear whose center is on the third axis C3.

[0054] The drive gear 41 has an upstream driver gear 43. The upstream driver gear 43 is centered on the third axis C3 and has a plurality of pins 44 that fit into slots 39 in the upstream driven gear 38 to intermittently rotate the upstream driven gear 38. The upstream driver gear 43 and the upstream driven gear 38 form a Geneva mechanism. In this embodiment, three pins 44 are provided at equal intervals (120-degree intervals) around the circumference of the upstream driver gear 43.

[0055] When the drive gear 41 rotates, the downstream driven gear 28 is continuously rotated by the downstream driving gear 42, and the pin 44 of the upstream driving gear 43 enters the slot 39 of the upstream driven gear 38, causing the upstream driven gear 38 to rotate intermittently in 60-degree increments.

[0056] In this embodiment, a linkage mechanism that links the rotational displacement of the downstream fin shaft 20 and the upstream fin 32 is formed by a drive gear 41 having a downstream driving gear 42 and an upstream driving gear 43, a downstream driven gear 28, and an upstream driven gear 38.

[0058] The light source 52 includes a light-emitting element such as an LED, and is provided outside the retainer 10. The light source 52 is provided outside the peripheral wall 22 of the downstream fin shaft 20. In this embodiment, the light source 52 is provided on the opposite side of the drive unit 40 in the vehicle width direction X. Note that in this embodiment, electricity is applied to the light source 52 to cause it to emit light while the air conditioning system is operating.

[0059] The light emitting device 50 is provided inside the peripheral wall 22 and has a light guide 53 that guides light emitted from the light source 52 into the interior of the peripheral wall 22 . As shown in FIGS. 1 and 12, the light guide 53 has a bottom wall 54, a top wall 55, a front wall 56, and side walls 57.

[0060] The lower wall 54 and the upper wall 55 face each other in the up-down direction Z and extend parallel to each other along the vehicle width direction X. The front wall 56 connects the front end edge of the lower wall 54 and the front end edge of the upper wall 55 and extends along the vehicle width direction X. The side wall 57 is provided at one end of the light guide 53 on the opposite side to the light source 52 in the vehicle width direction X.

[0061] The light guide 53 opens rearward and also toward the light source 52 . The light-emitting display unit 51 is provided on the downstream shaft 21, is visible through the air outlet 18, and displays the direction of the air for conditioning. The light-emitting display unit 51 is provided on the peripheral wall 22 of the downstream shaft 21, and is made of light-transmitting portions 23a to 23d that transmit light from the light guide 53. In this embodiment, the light-transmitting portions 23a to 23d are holes that penetrate the peripheral wall 22.

[0062] 2(a) to 2(c), the multiple light-transmitting portions 23a to 23d are provided at different positions in the circumferential direction of the peripheral wall 22. In this embodiment, the four light-transmitting portions 23a to 23d are provided at equal intervals, i.e., at 90-degree intervals, in the circumferential direction.

More specifically, the light-transmitting portion 23a is provided in the cutout portion 27 that faces the air outlet 18 when the first downstream fin 25 and the second downstream fin 26 are located in the first passage portion 17A and the second passage portion 17B, respectively. The light-transmitting portion 23a is provided on one side in the vehicle width direction X (the right side in FIG. 2(a)). In this embodiment, a plurality of auxiliary holes 24 having a diameter smaller than that of the light-transmitting portion 23a are provided alongside the light-transmitting portion 23a in the vehicle width direction X. The plurality of auxiliary holes 24 are provided on the other side in the vehicle width direction X of the light-transmitting portion 23a (the left side in FIG. 2(a)).

[0067] The positions of the multiple light-transmitting portions 23a to 23d in the vehicle width direction X when they are located opposite the air outlet 18 in the front-rear direction Y correspond to the wind direction in the vehicle width direction X of the air for air conditioning blown out through the air outlet 18.

[0068] Next, the relationship between the positions of the downstream fin shaft 20 and the upstream fin shaft 30, the wind direction of the air for conditioning blown out from the air outlet 18, and the display mode of the light-emitting display section 51 will be described.

[0069] <When the upstream fin shaft 30 is in the neutral position and the downstream fin shaft 20 is in the neutral position> 5, when the air for conditioning flows into the accommodation portion 14 from the connection portion 15, it flows into the first passage portion 17A and the second passage portion 17B along the second surface 36 and the first surface 34 of the upstream fin 32, respectively. Then, the air for conditioning is blown out from the air outlet 18 without being changed in wind direction while flowing through the first passage portion 17A and the second passage portion 17B.

[0070] As shown in FIG. 6, the light-emitting display portion 51 visible through the air outlet 18 is located at the center of the air outlet 18 in the vehicle width direction X. <When the upstream fin shaft 30 is in the first airflow direction control position and the first downstream fin 25 of the downstream fin shaft 20 is in the first passage portion 17A> 7, when the air for conditioning flows into the accommodation portion 14 from the connection portion 15, it flows into the first passage portion 17A along the first surface 34 of the upstream fin 32. Then, the air for conditioning flowing through the first passage portion 17A flows along the first downstream fin 25 as it passes through the first downstream fin 25.

[0071] As a result, as shown in FIG. 8, the direction of the conditioning air blown out through the air outlet 18 is changed to one side of the first direction X (the right side in FIG. 8), and the conditioning air is blown out downward.

[0072] Furthermore, the light-emitting display unit 51, which is visible through the air outlet 18, is located on one side of the air outlet 18 in the vehicle width direction X (the right side in FIG. 8). <When the upstream fin shaft 30 is in the second airflow direction control position and the first downstream fin 25 of the downstream fin shaft 20 is in the first passage portion 17A> As shown by the two-dot chain line in Fig. 7, the air for conditioning is subject to a change in direction by the second downstream fin 26 when it flows through the second passage portion 17B. As a result, the direction of the air for conditioning blown out through the air outlet 18 is changed to one side of the first direction X (the right side in Fig. 8), and the air for conditioning is blown out upward.

[0073] <When the upstream fin shaft 30 is in the first airflow direction control position and the second downstream fin 26 of the downstream fin shaft 20 is in the first passage portion 17A> 9, when the air for conditioning flows into the accommodation portion 14 from the connection portion 15, it flows into the first passage portion 17A along the first surface 34 of the upstream fin 32. Then, the air for conditioning flowing through the first passage portion 17A flows along the second downstream fins 26 as it passes through the second downstream fins 26.

[0074] As a result, as shown in FIG. 10, the direction of the conditioning air blown out through the air outlet 18 is changed to the other side of the first direction X (the left side in FIG. 10), and the conditioning air is blown out downward.

[0075] Furthermore, the light-emitting display unit 51, which is visible through the air outlet 18, is located on one side of the air outlet 18 in the vehicle width direction X (the left side in FIG. 10). <When the upstream fin shaft 30 is in the second airflow direction control position and the second downstream fin 26 of the downstream fin shaft 20 is in the first passage portion 17A> As shown by the two-dot chain line in Fig. 9, the air for conditioning is subject to a change in direction by the first downstream fin 25 when it flows through the second passage portion 17B. As a result, the direction of the air for conditioning blown out through the air outlet 18 is changed to the other side of the first direction X (the left side in Fig. 8), and the air for conditioning is blown out upward.

[0076] <When the upstream fin shaft 30 is in the second airflow direction control position and the downstream fin shaft 20 is in the neutral position> 11, when the air for conditioning flows into the accommodation portion 14 from the connection portion 15, it flows into the second passage portion 17B along the second surface 36 of the upstream fin 32. Then, the air for conditioning air is blown upward from the air outlet 18 without being subject to a change in wind direction while flowing through the second passage portion 17B.

[0077] As shown by the dotted line in Figure 11, when the upstream fin shaft 30 is in the first wind direction control position, the air for air conditioning is blown downward from the outlet 18 without any change in wind direction as it flows through the first passage section 17A.

[0078] <When the upstream fin shaft 30 is in the shutoff position and the downstream fin shaft 20 is in the neutral position> 12, upstream fin 32 blocks ventilation passage 17, thereby preventing the inflow of air-conditioning air from connection portion 15 to storage portion 14. As a result, air-conditioning air is no longer blown out through air outlet 18.

[0079] Next, the operation of this embodiment will be described. A drive device 40 that rotates the downstream shaft 21 and the upstream shaft 31 is provided on one side of the downstream shaft 21 and the upstream shaft 31 in the first direction X. This prevents the size of the air-conditioning register in the third direction Z from increasing due to the drive device 40.

[0080] Next, the effects of this embodiment will be described. (1-1) By achieving the effects of the above embodiment, it is possible to reduce the thickness of the air-conditioning register.

[0081] (1-2) The downstream shaft 21 and the upstream shaft 31 can be rotationally driven by a common drive gear 41. This allows the rotational displacement of the downstream fin shaft 20 to be linked to the rotational displacement of the upstream fin shaft 30. This allows the number of parts in the drive unit 40 to be reduced.

[0082] (1-3) As shown in Fig. 7 , when the first downstream fins 25 are positioned in the first passage portion 17A, the conditioning air flowing through the first passage portion 17A flows along the first downstream fins 25 as it passes through the first downstream fins 25. As a result, the wind direction of the conditioning air blown out through the air outlet 18 is changed to one side in the first direction X.

[0083] 9, when the first downstream fins 25 are positioned in the second passage portion 17B, the conditioning air flowing through the second passage portion 17B flows along the first downstream fins 25 as it passes through the first downstream fins 25. Here, the inclination direction of the first downstream fins 25 when positioned in the second passage portion 17B is opposite to the inclination direction of the first downstream fins 25 when positioned in the first passage portion 17A. As a result, the wind direction of the conditioning air blown out through the air outlet 18 is changed to the other side of the first direction X.

[0084] Further, the outer peripheral surface of the downstream shaft 21 is provided with a cutout portion 27 where the first downstream fin 25 is not provided in the circumferential direction of the downstream shaft 21. 5, the cutout portions 27 are located in the first passage portion 17A and the second passage portion 17B when the first downstream fin 25 is located on one side or the other of the downstream shaft 21 in the second direction Y. At this time, the conditioning air is blown out from the air outlet 18 without being changed in its direction as it flows through the first passage portion 17A and the second passage portion 17B. Furthermore, when the downstream fin shaft 20 is in the neutral position, the first downstream fin 25 is not located in the first passage portion 17A or the second passage portion 17B, so an increase in pressure loss can be suppressed. Therefore, it is possible to switch between a state in which the direction of the conditioning air blown out from the air outlet 18 is changed and a state in which the direction of the air is not changed.

[0085] (1-4) When the first downstream fin 25 is located in the first passage portion 17A, the second downstream fin 26 is located in the second passage portion 17B. Therefore, the air for conditioning flowing through the first passage portion 17A flows along the first downstream fin 25 when passing through the first downstream fin 25, and the air for conditioning air flowing through the second passage portion 17B flows along the second downstream fin 26 when passing through the second downstream fin 26. Here, the second downstream fin 26 has the same inclination direction with respect to the imaginary plane V as the first downstream fin 25. As a result, the wind direction of the air for conditioning air blown out through the air outlet 18 is changed to one side of the first direction X.

[0086] Furthermore, when the second downstream fins 26 are positioned in the first passage portion 17A, the first downstream fins 25 are positioned in the second passage portion 17B. Therefore, the air for conditioning flowing through the first passage portion 17A flows along the second downstream fins 26 when passing through them, and the air for conditioning air flowing through the second passage portion 17B flows along the first downstream fins 25 when passing through them. Here, the inclination direction of the second downstream fins 26 when positioned in the first passage portion 17A is opposite to the inclination direction of the second downstream fins 26 when positioned in the second passage portion 17B. As a result, the wind direction of the air for conditioning air blown out through the air outlet 18 is changed to the other side of the first direction X.

[0087] Therefore, the air direction can be changed to either side of the first direction X whether the air conditioning air flows through the first passage portion 17A or the second passage portion 17B. (1-5) By displacing the upstream fin 32 to any one of the first wind direction control position, the second wind direction control position, and the neutral position, it is possible to change the passage section through which the air for air conditioning flows, either the first passage section 17A or the second passage section 17B.

[0088] However, by providing the downstream fin shaft 20 inside the retainer 10, there is a risk that the air for air conditioning will collide with the downstream shaft 21, resulting in an increase in pressure loss. In this regard, according to the above configuration, the flow of the air-conditioning air is guided to either or both of the first passage portion 17A and the second passage portion 17B by the upstream fins 32. This prevents the air-conditioning air from colliding with the downstream shaft 21, thereby suppressing an increase in pressure loss.

[0089] (1-6) By rotating the upstream fin 32 about the second axis C2 extending in the first direction X, the upstream fin 32 can be displaced to the first wind direction control position, the second wind direction control position, and the neutral position.

[0090] (1-7) By blocking the ventilation passage 17 with the upstream fins 32, it is possible to prevent the air for air conditioning from being blown out through the air outlet 18. (2-1) When the light-emitting display unit 51 provided on the downstream shaft 21 emits light, the user can grasp the direction of the air for conditioning by visually checking the light-emitting display unit 51 through the air outlet 18. Therefore, even if the width of the air outlet 18 is small, the visibility of the part indicating the direction of the air for conditioning is improved.

[0091] (2-2) Light emitted from the light source 52 is guided into the peripheral wall 22 through the light guide 53 and is radiated to the outside of the downstream shaft 21 through the light-transmitting portions 23a to 23d provided on the peripheral wall 22. Therefore, even though the light source 52 is provided outside the downstream fin shaft 20, the light-transmitting portions 23a to 23d provided on the peripheral wall 22 of the downstream shaft 21 can be made to emit light.

[0092] (2-3) The user can intuitively grasp the direction of the air conditioning air in the first direction X from the positions of the light-transmitting portions 23a to 23d in the first direction X that are visible through the air outlet 18.

[0093] (2-4) The light-transmitting portions 23a to 23d are holes that penetrate the peripheral wall 22. Therefore, the light-transmitting portions 23a to 23d can be realized with a simple configuration. <Modification> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0094] The auxiliary holes 24 may be omitted. The light-transmitting portions 23c and 23d may be omitted. The light-transmitting portions 23a to 23d are not limited to holes that penetrate the peripheral wall 22. The light-transmitting portions 23a to 23d can also be realized by forming a part of the peripheral wall 22 from a visible light-transmitting material.

[0095] In the above embodiment, the plurality of light-transmitting portions 23a to 23d may be provided at the same position in the vehicle width direction X. In this case, the light-transmitting portions 23a and 23b may be shaped like an arrow to indicate the flow direction of the air for air conditioning.

[0096] The light source may be disposed inside the peripheral wall 22. In this case, the light guide 53 can be omitted. In the above embodiment, the light-emitting display unit 51 is provided on the downstream shaft 21, but it may also be provided on the downstream fins (first downstream fin 25, second downstream fin 26) in addition to or instead of the downstream shaft 21.

[0097] The light emitting device 50 may be omitted. The number of slots 39 of the upstream driven gear 38 and the number of pins 44 of the upstream driving gear 43 can be changed as appropriate.

[0098] The upstream fin 32 may not be displaceable to the blocking position. The drive unit 40 is not limited to one equipped with a drive gear 41. Alternatively, for example, the downstream fin shaft 20 and the upstream fin shaft 30 may be driven by different motors. In other words, the interlocking mechanism that interlocks the rotational displacement of the downstream fin shaft 20 and the rotational displacement of the upstream fins 32 may be omitted.

[0099] The second downstream fin 26 may be omitted. The cutout portion 27 may be omitted. That is, downstream fins may be provided over the entire outer circumferential surface of the downstream shaft 21 in the circumferential direction.

[0100] The air outlet 18 may be flattened so that its length in the vehicle width direction X is shorter than its length in the up-down direction Z. In this case, the configuration of the air conditioning register may be changed so that the up-down direction Z is the first direction and the vehicle width direction X is the third direction.

[0101] The air conditioning register is not limited to being provided in the instrument panel, but may be provided in a console box, ceiling, or the like. [Explanation of symbols]
