Description

[Detailed Description of the Invention] Industrial Application Field The present invention mainly relates to an improvement of a wind direction adjustment device for an air conditioner for an automobile.

BACKGROUND ART A conventional means for removing fog from a side window of an automobile or the like involves extending a side defroster duct from a front window defroster and assembling a side defroster nozzle to the side defroster duct.

Side ventilators are also used to remove fog from the side windows.

As a device for carrying out the latter method,
Structures shown in Japanese Utility Model Application Publication No. 200411, Japanese Utility Model Application Publication No. 58-179212, or Japanese Utility Model Application Publication No. 59-60014 have been proposed.

However, the structure with the above-mentioned side defroster nozzle has the disadvantage that the design of the vehicle interior is spoiled because the side defroster nozzle is attached.Furthermore, the number of parts such as the side defroster duct and side defroster nozzle and the number of assembly man-hours increase, which increases the cost. An additional drawback was that the nozzle had a small opening area, so the fog removal range was also narrow.

Also, Utility Model Application No. 57-200411 and Utility Model Application No. 59-
Although the device disclosed in Japanese Patent No. 60014 eliminates the above-mentioned drawbacks, the operating mechanism is large and occupies a large area, making it difficult to incorporate it into an instrument panel.

Furthermore, the device disclosed in Japanese Utility Model Application No. 58-179212 has the drawback that when attempting to defog the side window, the driver's hand must be extended out from the driver's seat, making it difficult to operate.

As a solution to these shortcomings, Jitsuganaki
There are those described in the specification of No. 59-176246 and the specification of No. 59-177535.

The air blowing barrel is supported by a rotation shaft in the bezel of the side ventilator so that it can rotate vertically or horizontally, and the cam attached to the rotation shaft is Alternatively, a rod for rotating the horizontal blade in the left and right or up and down directions is engaged, and a remote control mechanism is attached to the drive device for the rotation shaft, and with such a configuration, The air blowing barrel in the bezel of the side ventilator and the vertical or horizontal blades in the barrel can be remotely controlled with a simple mechanism, and can be incorporated into the instrument panel with a large degree of freedom in design. In addition, the design of the vehicle interior is improved, the fog removal performance of the side windows is improved, and the cost is reduced.

Problems that the invention attempts to solve
No. 177535 does not have a damper inside the bezel, so it has the disadvantage that it is difficult to adjust the air volume when used as a regular air conditioning ventilator.
Furthermore, since there is a lot of play between the blade and the rod, there is a risk that it will be difficult to adjust the angle of the blade.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an air blowing barrel in which an air blowing barrel is rotatably supported by a barrel rotation shaft in a bezel of a side ventilator. A cam is rotatably fitted on the shaft via a friction clutch, the cam is operatively connected to a drive part of a remote control mechanism, and the blade in the air blowing barrel is connected to the blade via the friction clutch. A rotation rod is engaged, and the rod is interlocked and connected to the cam, and a damper is rotatably disposed on the bezel by a damper rotation shaft, and the damper is rotatably disposed on the bezel. The rotating shaft is operatively connected to a drive section of a remote control mechanism connected to the cam.

Operation When the remote control mechanism is operated while the side ventilator is in a normal air conditioning state, the damper is fully opened and the barrel and blade are rotated toward the side window. This causes warm air to flow toward the side windows, removing fog that has formed on the side windows.

On the other hand, if any excessive resistance occurs in the drive system between the remote control mechanism and the barrel, etc., or if you manually operate the barrel directly, Each member operates smoothly without damage due to the action of a friction clutch provided on each blade rotation shaft.

Further, when the side ventilator is used for normal air conditioning, the damper, barrel and blade are freely manually operated by the friction clutch despite resistance from the remote control mechanism. Further, the air volume is adjusted by adjusting the rotation angle of the damper.

Embodiment FIGS. 1 to 7 show a first embodiment, and as shown in FIG. 9, a side ventilator 26 of an instrument panel 25 of an automobile,
27 applies.

Figures 1 and 2 show the left side ventilator 2.
6, and there is a vertical blade 13 inside the bezel 12.
An air blowing barrel 11 having a diameter is arranged.

The air blowing barrel 11 described above is rotatably supported in the vertical direction as shown by the double arrow C by the barrel rotation shaft 6 in the shaft support hole 28 of one side wall thereof, and the support shaft fixed to the other side wall. Bezel 1 by 29
It is rotatably supported in the shaft support hole 30 of No. 2.

As clearly shown in FIG. 3, the barrel rotation shaft 6 has a radial protrusion 31, and the support shaft 29 has a radial protrusion 33 on a narrow diameter portion 32, while the shaft 29 has a radial protrusion 33 in the narrow diameter portion 32. The shaft support hole 34 corresponding to No. 28 is formed with a groove 35 into which the protrusion 31 is inserted, and the shaft support hole 30 has a circular arc groove 37 longer than the arc length of the projection 33 on the outer periphery of the shaft hole into which the narrow diameter portion 32 is inserted. are formed, and both ends of the arcuate groove 37 of the shaft support hole 30 cooperate with the protrusion 33 of the support shaft 29 to function as stoppers for regulating the upper and lower limits of rotation of the air blowing barrel 11. Incidentally, reference numeral 9 in FIG. 4 is a nut for fixing the barrel rotation shaft 6 to the barrel 11.

A cam 5 is coaxially fitted into the barrel rotation shaft 6 mentioned above. The cam 5 is operated by a remote control mechanism, which will be described later, and is a cylindrical cam that forms part of a drive device for the barrel rotation shaft 6. This cam 5
As shown in FIG. 4, a friction clutch is formed between the rotation shaft 6 for the barrel and the rotation shaft 6 for the barrel. The end surface of the cam 5 is in contact with this. Cam 5 is hollow,
A coil spring 7 is fitted into the barrel rotation shaft 6 that protrudes into the hollow.
is compressed between the screw 8 passed from the shaft end side and the cam 5.

As a result, when rotational force is applied to the cam 5, the barrel rotation shaft 6 also rotates due to the frictional force between the disc 38 and the end surface of the cam 5, and the protrusion 33 is attached to the end of the arcuate groove 37. The barrel 11 rotates until it hits, regulating the blowing direction of the wind in the vertical direction. Also, cam 5
When the barrel 1 is rotated, the protrusion 33 is already in contact with the end of the arcuate groove 37, or the barrel 1 is rotated.
When manually operating the cam 5, the disc 38 and the end surface of the cam 5 slip, so that excessive force is applied to the barrel rotation shaft 6.
etc. will not participate.

A pinion gear 36 is formed concentrically on the cam 5, and the rack 4 that meshes with the pinion gear 36 is arranged along the outer wall 39 of the bezel 12 so that it can move forward and backward in the direction of the double arrow D.
The cam 5 is configured to be able to rotate in the direction of arrow C by the forward and backward movements of the cam 5.

A remote control mechanism is connected to the rack 4 mentioned above. That is, as shown in FIG. 2, the tip of the cable 2 guided by the clamp 3 fixed to the outer wall 39 of the bezel 12 is fixed to the rack 4, and the rack 4 is moved forward and backward as the cable 2 moves forward and backward. .

The rear end of the cable 2 is connected to the side ventilator 26
is locked to one end of a lever switch 1 rotatably supported by a shaft 40 at an operating position remote from the
A knob 41 projecting from the center of the instrument panel 25 is provided at the other end of the lever switch 1.

As shown in FIGS. 1 to 5, the cam groove 42 of the cam 5 has a groove shape that gradually moves outward from the air blowing barrel 11 side.

Further, the window hole 4 of the outer wall 39 of the bezel 12 described above
A rod 10 is fitted into the rod 3 so that it can move forward and backward.

As clearly shown in FIG. 5, this rod 10 engages with one of the vertical blades 13 at the notch 44, and fits into the cam groove 42 of the cam 5 at the protrusion 45 at the outer end, causing the rotation of the cam 5. As a result, the cam groove 42 moves forward and backward in the direction of the double arrow G, and as shown in FIG. 5, the vertical blades 13 connected in series by the connecting rod 22 are rotated in the direction of the arrow H.

The notch 44 of the rod 10 is engaged with one of the vertical blades 13 via a substantially U-shaped blade lever 14 as also shown in FIG. Blade rotation shafts 46 that serve as rotational fulcrums are fixed to the vertical blades 13 at the top and bottom, but in the case where the blade lever 14 is attached, the lower part 47 of the blade lever 14 is inserted into the center. A notch 48 is provided, and a rotation shaft 46 is also protruded therefrom. The blade lever 14 has a disk 4 on its upper part.
9 is attached to the vertical blade 13 so that its disk 49 fits into the upper and lower rotational shafts 46, and the lower part 47 of the blade lever fits into the rotational shaft 46 at the intermediate position, respectively. rod 10
It is inserted into the notch 44 of.

In addition, a disk 5 that is in contact with the vertical blade 13 corresponds to the disk 49 of the blade lever 14.
0 is fixed, and both discs 49 and 50 are attached to the plate spring 15 inserted into the blade rotation shaft 46.
They are mutually pressurized by the blade lever stopper 16 and cannot be separated. These disks 49, 50, etc. constitute a friction clutch.

As a result, when the rod 10 moves, the blade lever 14 also rotates in the direction of the double arrow B, and the vertical blade 13 also rotates due to the action of the friction clutch. However, when force is applied manually from the vertical blade 13 side without applying force from the cam 5 side, the discs 49 and 50 slip, so that the force is applied smoothly without interfering with the input or resistance on the remote control mechanism side. Manual operations can also be performed.

As shown in FIGS. 1 and 7, the bezel 12 is provided with a damper 1 via a damper rotation shaft 51.
7 is installed, and the damper 17 is also connected to the barrel rotation shaft 6.
It is linked with the drive device of. Damper 17
has a shape and size that covers the rear air inlet of the bezel 12, and a disc 52 is fixed coaxially to a portion of the rotating shaft 51 that protrudes from the side wall 39 of the bezel 12. A damper lever 18 having a flat surface that can come into surface contact with the damper lever 18 is inserted, and a plate spring 19 and a damper lever stopper 20 are further inserted. These discs 52 and the like constitute a friction clutch.

The damper lever 18 also has a damper rotation shaft 5.
A pin 53 protruding in the same direction as 1 is provided, and a lever portion 54 located above this pin 53 is provided.
is provided protruding from the rack 4.

Further, a gear portion 55 that is integrated with the damper 17 is fixed to the other end side of the damper rotation shaft 51, and the knob 21 having a gear portion 56 that meshes with the gear portion 55 is fixed to the other end side of the damper rotation shaft 51. It is loosely fitted onto the shaft 29.

Therefore, the remote control mechanism moves the rack 4 diagonally downward, and the lever portion 54 engages with the pin 53 of the damper lever 18, causing the damper 17 to rotate.
Open the rear of bezel 12. However, when adjusting the damper 17 by operating the knob 21, the gap between the disc 52 and the damper lever 18 will slip even if there is a large resistance from the rack 4 side, so the opening degree of the damper 17 cannot be adjusted freely. You will get it.

The embodiment described above operates and functions as follows.

That is, the air blowing barrel 11, the vertical blade 13, and the barrel rotating shaft 6 occupy the neutral position, and the left side ventilator 26 when removing fogging from the upper left side window will be explained first. 1 knob 4
1 to the left, the rack 4 moves backward via the cable 2, the cam 5 integrated with the pinion gear 36 rotates in the direction of arrow E, and the barrel rotation shaft 6 also rotates with the cam due to the action of the friction clutch. At the same time as 5, it rotates in the direction of arrow E. And the protrusion 31 of the barrel rotation shaft 6
The air blowing barrel 1
1 is rotated diagonally upward with respect to the bezel 12,
The support shaft 29 of the air blowing barrel 11 also rotates at the same time, and its protrusion 33 contacts the upper end of the arcuate groove 37 of the shaft support hole 30 of the bezel 12, which is the upper stopper, thereby causing the air blowing barrel 11 to rotate. will be stopped.

Further, since the lever part 54 of the rack 4 pushes down the pin 53 of the damper lever 18, the damper 17 is rotated in the direction of arrow A as shown in FIG. 7, thereby opening the rear opening of the bezel 12. .

Furthermore, as the cam 5 rotates, the rod 10 is pulled out to the outside of the bezel 12, so the vertical blade 13 rotates together with the blade lever 14 in the direction of arrow H and stops.

Such a damper 17, air blowing barrel 11
By rotating the vertical blade 13, the direction of the blown wind is directed toward the side window, and the fog on the window is removed.

On the other hand, when the lever switch 1 is rotated in the opposite direction, the rack 4 and the like are also driven in the opposite direction, and the barrel 11 and the vertical blade 13 return to the neutral position.
However, since the lever portion 54 of the rack 4 is merely in contact with the pin 53 of the damper lever 18,
When the rack 4 is moved in the opposite direction, the damper lever 18 is not activated, so that the damper 17 remains closed.

In addition, when directly operating the damper 17, barrel 11, and vertical blade 13 manually for normal air conditioning, hold the knob 21, the knob 57 fixed to one of the vertical blades 13, and the front part of the barrel 11. Let's do it. When the knob 21 is rotated, the gear portion 5
Rotation is transmitted from 6 to the gear part 55 of the damper 17,
The damper 17 is rotated to an angle that allows the desired air volume to be obtained. At this time, slipping occurs between the disc 52 and the damper lever 18, so even if the pin 53 and the lever part 54 are in the engaged state, no unreasonable force is applied to the damper rotation shaft 51, the rack 4, etc. . Furthermore, when the knob 57 is rotated, the vertical blade 13 is also rotated to an angle that allows the desired wind direction to be obtained, and this rotational force causes an excessive force on the blade lever 14 etc. due to the slippage that occurs between the disc 49 and the disc 50. It doesn't come across as such. Also, when the front part of the barrel 11 is pressed in the vertical direction to rotate the barrel 11, the rotational force is not directed toward the cam 5, the rack 4, etc. due to the slip between the disc 38 and the end surface of the cam 5. It does not transmit excessive force and therefore allows smooth manual operation.

FIG. 8 shows the second and third embodiments together, and while the first embodiment uses the lever switch 1 to move the rack 4 forward and backward, the second embodiment uses the lever switch 1 to move the rack 4 forward and backward.
In the embodiment, a motor 23 that rotates forward and backward is used,
In the third embodiment, a vacuum actuator 24 is used, and the configuration of other parts is completely the same as in the first embodiment.

Effects of the invention The present invention has the configuration and operation described above, and allows remote control of the air blowing barrel in the bezel of the side ventilator and the blades in the barrel with a simple mechanism, and furthermore, This has the effect that it can be incorporated into the system with a large degree of freedom in design.

In addition, since a friction clutch is provided on each of the damper rotation shaft, barrel rotation shaft, and blade rotation shaft, the damper, barrel, and blade can be operated manually without interference with the remote control mechanism. Moreover, since there is no need to set any clearance between the remote control mechanism and the barrel or blade, etc., it is also possible to return the side defroster state to the neutral state by remote control. It is possible.

Furthermore, since the damper is provided, when the side ventilator is used for normal air conditioning, the amount of air blown out from the side ventilator can be freely adjusted.
