Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a swing louver drive mechanism.

(Prior Art) For example, in a swing louver for automobiles, a fin body for adjusting a wind direction arranged at a wind outlet is pivotally attached to an upper and lower louver frame, and a driving force of an electric motor or the like is transmitted through a connecting member. It is like this.

When a plurality of outlets are provided in such a swing louver, usually, one drive motor is provided at each outlet to individually operate the fins, but a single drive motor is used. In some cases, it may be preferable to operate them as a whole.

(Problems to be solved by the invention) However, in the case where the fins of the plurality of outlets are arranged in one horizontal row, when the outlets are in one horizontal row, they can be swung by a single connecting member. However, as shown in FIG. 1, when the outlet is curved, the connecting member itself must have rigidity in the swinging direction, so it is difficult to swing it with a single drive motor. The current situation is.

Therefore, an object of the present invention is to provide a drive mechanism capable of simultaneously driving each fin body row with a single drive source and a connecting member even when the outlets are not in one row.

(Means for Solving the Problems) The present invention is to connect all the fins by a single continuous connecting member by connecting the connecting members for swinging the fin body row of the outlets at least with a connecting portion having flexibility. It was made paying attention to the fact that the body can be swung, and a plurality of fin bodies for adjusting the wind direction that are swingably arranged at the air conditioning outlet are arranged, and a power source is used to interpose a connecting member. In the swing louver that swings the fins, the connecting member that swings the fin body at the outlet is made of a flexible soft plastic material, and has a plurality of boss engaging holes, and Engaged and interconnected, at least part of the connection between the boss engagement holes is flexible, forming a continuous flexible link, one end of which is connected to the drive source Characterized by being In the drive mechanism of the swing louvers.

In the present invention, a flexible soft plastic material is used to impart rigidity in the swing direction to the swing shaft portion that engages with the fin body, while one end is provided in order to give the connecting portion flexibility. The other end of the string-shaped flexible link that connects to the drive source is locked to the spring to provide tension in the longitudinal direction to provide rigidity in the swing direction, and the connection portion is flexible in the direction orthogonal to the swing direction. Or the rocking shaft is molded so as to have a certain thickness in the direction orthogonal to the longitudinal direction so as not to have flexibility in the longitudinal direction, that is, the rocking direction, and at least the connecting portion. It can be achieved by forming a part of the structure so that it has no thickness in the direction orthogonal to the longitudinal direction and has flexibility in the swinging direction.

(Operation) According to the present invention, since the swing shaft portions that engage with the fin body rows that are arranged to face the air outlet are flexibly connected,
Even if a plurality of fin body rows are arranged in a curved manner, all the fin bodies are interlocked by connecting one end of a connecting member forming a string-like flexible link to a single drive source for driving. Can be rocked. Further, since one end of the flexible string-like body is connected to the crank portion of the drive source, the long hole is not required and the swinging operation can be performed smoothly.

Hereinafter, the present invention will be described in detail based on specific examples shown in the accompanying drawings.

(Embodiment) FIG. 1 is a perspective view showing an outer case 1 of an air conditioner in which air outlets are not arranged in a line in a horizontal line and arranged slightly curved, and the inside thereof is as shown in FIG. There is.

That is, 2 is a drive source, which is composed of an electric motor and a speed reducer, a crank 22 is attached to its drive shaft 21, and a crank pin 22a is projected at the tip thereof.

A first swing louver 3 and a second swing louver 3 are provided on the side of the drive shaft 2.
The swing louver 4 and the third swing louver 5 are arranged in the front and rear. Each swing louver has four vertical fin bodies 31, 41, 51, which are bosses 32, 42, which project rearward from the upper and lower surfaces.
The case 1 is connected by the connecting frames 33, 43, 53 that engage with 52.
The bosses 34, 44, 54 projecting from the front upper surface are connected to the crank pin 22a at one end, while the other end is attached to the case 1 via the spring 6 It engages with boss engaging holes 71a, 72a, 73a formed in the string-shaped flexible link 7 forming the connecting member (see FIG. 5), and integrally links by swinging the flexible link 7. And can be swung. The flexible link 7 is manufactured from a soft plastic material having a slight elasticity such as nylon or polypropylene. A horizontal fin body 8 is disposed in front of the vertical fin body array so as to face the opening 11 as shown in FIG.

In the above structure, the flexible link 7 is made of a soft plastic material and has flexibility as a whole, but is adjusted by the spring 6 to be stronger than the sliding resistance of the fin body and weaker than the driving force of the motor. Since the tension is applied to the link 7 by the urging force, the portions (swing shaft portions) 71, 72, 73 functioning as the connecting members are provided with rigidity for swinging the fin body, while the connecting portions are provided. 74, 75, 76 are made to retain their flexibility in the front-rear direction and slid between the pair of guide members 12, 12.

Therefore, even if the vertical fin bodies 31, 41, 51 do not form one row in the horizontal direction but are bent and arranged in the front-back direction, all of them can be driven by the single drive motor 2 via the single flexible link 7. The vertical fin bodies 31, 41, 51 can be driven in association with each other.

In FIG. 6, the flexible link 7 is formed of a soft plastic body as in the above embodiment. However, as shown in FIG. 7, the shape is different and the boss engagement with the vertical fin bodies 31, 41, 51 is different. Portions 71, 72, 73 corresponding to the swing shaft portion having a dowel hole and the engaging portion
77 becomes wider in the direction orthogonal to the longitudinal direction, and is provided with rigidity that can push and pull the fin body in the longitudinal direction, and the portions 74, 75, and 76 corresponding to the connecting portions are allowed in the direction orthogonal to the longitudinal direction. Wide to the top and bottom to give flexibility, Case 1
It is slidably arranged in the guide groove 13 formed in the. The connecting portion has a spherical portion 74 so that it has flexibility in the vertical and horizontal directions.
It may be formed by combining a and the linear portion 74b (see FIG. 8), whereby the spherical portion is guided by the guide portion 12 and smooth movement can be ensured. Since the other parts are the same as those in FIG. 2, the same parts are designated by the same reference numerals and the description thereof is omitted.

Although a plurality of outlets have been described in the above embodiment, 1
The present invention can also be applied to a case where a plurality of fins of individual air outlets are connected.

(Effects of the Invention) As is clear from the above description, according to the present invention, a plurality of fin bodies for adjusting the wind direction that are swingably arranged at the air conditioning outlet are arranged and connected by a power source. In a swing louver that swings through a member, a flexible soft plastic material is used to impart rigidity to the swing shaft that engages with the fin body to perform the swing function, while providing flexibility to the connecting portion. Since the swing shaft portions that engage with the fin body rows facing the air outlet are flexibly connected to each other, even if the fin body rows are arranged in a plurality of curves, a string-shaped flexible body is provided. All fins can be oscillated by interlocking by driving one end of the connecting member forming a sex link to a single drive source, and the swing louver swing mechanism can be manufactured inexpensively and compactly. can do.

Further, since one end of the flexible link is connected to the crank portion of the drive source, the long hole is not required and the swinging operation can be performed smoothly.
