[0068] Next, referring to the drawings, a damper opening and closing device according to a first embodiment will be described.

[0069] figure 1 It is a plan view showing the periphery of the air outlet 80 of the vehicle instrument panel 8 . Such as figure 1 As shown in , the damper opening and closing device 10 according to the first embodiment is provided in the air outlet 80 of the instrument panel 8 of the vehicle. The damper opening and closing device 10 includes a main body 25 and a holder 6 in which the main body 25 is pivotably held. The main body 25 includes an outer cylinder 1 , an inner cylinder 2 , a damper group 30 composed of a plurality of dampers 3 , and an operation part 5 .

[0070] figure 2 is along figure 1 The cross-sectional view of arrow A-A in the middle, and, image 3 is along figure 1 Cross-sectional view of middle arrow B-B. Figure 4 It is an exploded perspective view of the damper opening and closing device 10 . Such as figure 2 As ...

[0103] Such as Figure 13 and Figure 14 As shown in , three rectifying fins 51 are radially arranged in the center of the operation portion 5 . In addition, the arc-shaped fin portion 38 protrudes from the inner surface of the damper body 31 of each damper 3 toward the central axis of the flow path 7 . Seen from the air outlet 80 on the downstream side, the rectifying fins 51 of the operating portion 5 and the fin portions 38 of the damper 3 are alternately arranged at equal intervals in the circumferential direction. The rectifying fins 51 and the fin portion 38 have a thin plate shape, and are arranged in the axial direction. The air conditioning air 70 flowing through the flow channel 7 is rectified by the rectifying fins 51 and the fin portion 38 , and then blown out through the air outlet 80 . Accordingly, the rectification effect of the air-conditioning wind is good.

[0105] In the third embodiment, the semicircular portion 35 protrudes from the outer surface of the damper main body 31, such as Figure 15 and Figure 16 shown in . A gear 39 constituted by a helical gear is formed on the outer peripheral edge of the semicircular portion 35 . The semicircle 35 fits into the cutout 24 formed in the inner barrel 2 . A rack 19 constituted by an internal gear is formed on the inner peripheral surface of the outer cylinder 1, and the rack 19 is provided continuously over the entire circumferential direction thereof. The gear 39 of the damper 3 is meshed with the rack 19 of the outer tube 1 . When the inner tube 2 is rotated by the operation of the operation part 5 , the gear 39 of the damper 3 is moved along the tooth groove axis of the rack 19 . The damper 3 swings around the support portion 32 through the axial movement of the gear 39 , and opens and closes the flow channel 7 . The gear 39 and the rack 19 constitute an angle control device ...

Abstract

A damper opening and closing device includes an outer cylinder, an inner cylinder that is disposed inside the outer cylinder, is supported movably relative to the outer cylinder and has a fluid passage therein, and a damper group that includes a plurality of dampers disposed in the fluid passage so that the fluid passage is openable and closable. The plurality of dampers are arranged in a circumferential direction of the fluid passage and disposed in the fluid passage in such a way that inner peripheral edges of the dampers are opposed to each other. The damper opening and closing device further includes an angle control unit configured to control the tilt angle of the damper in conjunction with movement of the inner cylinder relative to the outer cylinder.

Description

technical field [0001] The invention relates to an air door opening and closing device, which is used for adjusting the flow rate of fluid flowing through a flow channel. Background technique [0002] In the related art, a damper opening and closing device is disclosed in JP-A-2002-168511. of this application manual Figure 27 It is a figure corresponding to the exploded isometric view of the damper opening and closing device disclosed in JP-A-2002-168511. Such as Figure 27 As shown in , the damper opening and closing device includes: a housing 912 having a flow channel 925 therein; an operating body 914 movably supported in the flow channel 925 and having a rack portion 944 and an operating portion 946; and Fin 918. The fins 918 are respectively provided with a gear portion 957 meshing with the rack portion 944 , and the fins 918 are pivotally supported by the case 912 radially from each other. [0003] In this structure, the operation body 914 is moved back and forth b...
