Abstract

Disclosed is an air conditioner for a vehicle, wherein in accordance with an assembly direction in which a door having an arm pivot and a temporary arm pivot formed therein is inserted into an air conditioning case including a first elongated hole and a second elongated hole in which the arm pivot and the temporary arm pivot are stored, the door can be bound or prevented from being bound by a cam. An actuator can control rotation of the door when the door is not bound by the cam to use an armless air conditioning case in which an arm or a lever are not equipped as it is without designing the air conditioning case again to implement an ADS function. Therefore, the number of components can be significantly reduced and, at the same time, the ADS function can be implemented by independent control of the door.

Description

Automotive air conditioning unit {AIR CONDITIONING DEVICE FOR VEHICLE}

The present invention relates to a vehicle air conditioner, and more particularly, to a vehicle air conditioner that enables independent control of the door while still using the air conditioner with a cam for controlling the rotation of the door.

The vehicle air conditioner is a vehicle interior that is installed for the purpose of securing the driver's front and rear view by removing the frost that is caught in the windshield during the rainy season or winter, or cooling the vehicle interior in the summer or winter. Such a vehicle air conditioner is usually equipped with a heating device and a cooling device at the same time to selectively introduce the outside air or bet and then heat or cool the air and blow it into the vehicle interior to cool, heat or ventilate the interior of the vehicle.

According to the independent structure of the blower unit, the evaporator unit and the heater core unit, the vehicle air conditioner has a three-piece type in which the three units are independently provided, the evaporator unit and the heater core unit are built in the air conditioning case, and the blower unit The semi-center type is provided as a separate unit, and all three units can be roughly divided into a center mounting type built in the air conditioning case.

As such, the vehicle air conditioner is provided in the form of an air conditioning case. In the air conditioning case, an air inlet and an air outlet are provided at the outside, and at least one air passage is provided at the inside. Air introduced into the air conditioning case through the air inlet passes through the evaporator and the heater core along the air passage and is discharged to the outside of the air conditioning case through the air outlet.

The air passage and the air discharge port is provided with a door to adjust the opening degree. Through the door it is possible to regulate the air flow inside the air conditioning case and to provide air harmonized in the desired position and direction. The air outlet may consist of a defrost vent, a face vent and a floor vent. The door may be configured with a mode door for adjusting the opening degree of the air discharge port, and a temperature control door for controlling the temperature of the air conditioning air. The mode door is composed of a vent door for adjusting the opening degree of the defrost vent and the face vent, and a floor door for adjusting the opening degree of the floor vent.

1 is a side view showing a part of a conventional vehicle air conditioner from the outside, Figure 2 is a perspective view showing a door of a conventional vehicle air conditioner.

As shown in FIG. 1, the vent door 17 and the floor door 18 rotate the arms 21 and 27, the levers 22 and 26, and the cam shaft 29 that are installed on the outside of the air conditioning case 10. The operating angle is controlled by the cam 24. That is, the rotation shaft of the vent door 17 is rotatably connected to one side of the arm 21, the other side of the arm 21 is rotatably connected to one side of the lever 22 and the other of the lever 22 The side is connected to the slot 23 of the cam 24.

In addition, the rotation axis of the floor door 18 is rotatably connected to one side of the arm 27, the other side of the arm 27 is rotatably connected to one side of the lever 26, The other side is connected to the slot 25 of the cam 24. As the cam 24 is rotated by an operation of a mechanically operated controller (not shown), the vent door 17 and the floor door 18 are interlocked with each other.

As shown in FIG. 2, for example, the vent door 17 is integrally formed with the door shaft 30. The portion 31 extending from the end of the door shaft 30 is held hingeably with respect to the case 10 by passing through a hole formed in the air conditioning case 10. The arm 21 is fixed to the end 31 of the door shaft 30 outside of the case 10. That is, to open and close the vent door 17, the arm 21 is rotated using the cam 24. That is, in the past, a separate driving source is coupled to each door 17 and 18 without using the cam 24, but by using the cam 24, there is an advantage of reducing the number of parts. Accordingly, in the conventional vehicle air conditioner, the cam 24 is driven by a driving source, and the driving force is transmitted to the lever 22, and the lever actuates the arm 21 again, and the arm 21 of the door 17 is operated. The door 17 is operated in connection with the rotation shaft.

However, such a conventional air conditioner also needs to be provided with the lever 22 and the arm 21 separately, respectively, so that the devices for operating the door 17 have a problem in that the number of parts increases and the cost increases. There was a problem of leakage of air according to.

In addition, since the vent door 17 and the arm 21 formed integrally with the shaft 30 are manufactured as separate parts, the vent door 17 may not stop at a desired position when they are operated by assembling each other. This is due to the accumulation of assembly tolerances that arise in the process of assembling separate parts. In addition, within the normal tolerance range, the vent door 17 and the arm 21 may be vibrated mutually, and there is a problem of an increase in the man-hours due to mutual assembly of parts and an increase in costs incurred in the manufacture of separate parts. .

7 is a perspective view illustrating the door 100 provided in the vehicle air conditioner according to an embodiment of the present invention, FIG. 8 is a perspective view of the door 100 of FIG. 7 enlarged in an end 121 direction, and FIG. 9. 7 is a side view enlarged in the direction of the end 121 of the door 100 of FIG.

As shown in FIG. 7, the vehicle air conditioner according to the present embodiment includes at least one or more doors 100 installed to be opened and closed at a predetermined position of the air conditioning case 200, and the door 100 includes a plate 110 and a shaft. 120 is integrally formed. In addition, a seal portion 130 having a circular edge of a predetermined height is formed at an end 121 of the shaft 120, and an arm pivot 140 and a temporary arm pivot 150 are formed at an edge portion of the seal portion 130. It is formed integrally.

Since the door 100 has a form of an armless air conditioner in which the arm pivot 140 and the temporary arm pivot 150 are integrally formed, the accumulation of assembly tolerances generated in the process of assembling the door and the arm in the related art is reduced. In addition, there is an effect of suppressing the increase in the man-hours caused by the mutual assembly of the parts and the increase in costs incurred in the production of the separate parts.

In addition, the end 121 of the shaft 120 is rotatably fixed to the inside of the air conditioning case 200, and has a function of maintaining the hinge is possible. The seal portion 130 is fitted to one side of the projection of the air conditioning case 200 has a function to seal the internal air of the air conditioning case 200 does not count (see Fig. 12).

As shown in FIG. 8, the arm pivot 140 protrudes from the end portion 121 of the shaft 120 at predetermined intervals and protrudes from the seal portion 130. The pin portion 141 and the both sides of the pin portion 141 are formed. And ribs 142 formed integrally. At this time, the rib 142 is integrally formed on both sides of the pin portion 141 in the rotational direction of the pin portion 141 to reinforce the rigidity of the pin portion 141, and the rib 142 is the first to be described later Guided to the guide case 240 is inserted.

Similarly, the temporary arm pivot 150 is spaced apart from the end 121 of the shaft 120 by a predetermined interval, and protrudes from the seal 130 in the opposite direction of the arm pivot 140 about the end 121. It includes a pin portion 151, and ribs 152 integrally formed on both sides of the pin portion 151. At this time, the rib 142 is guided by being fitted to the second guide case 250 to be described later.

The rib 142 may be formed to be narrowed in the end direction of the pin portion 141. That is, the lower side is wider in the drawing direction and is narrower toward the upper side to form an inclined surface. Similarly, the rib 152 may be formed to be narrowed in the end direction of the pin portion 151.

As shown in FIG. 9, the arm pivot 140 and the temporary arm pivot 150 protrude from the seal portion 130 at positions symmetrical with respect to the end 121 and have different lengths.

In detail, the pin portion 141 of the arm pivot 140 protrudes more than the pin portion 151 of the temporary arm pivot 150. Accordingly, the pin portion 141 of the arm pivot 140 may be combined with the cam 230 to be described later. On the contrary, the pin portion 151 of the temporary arm pivot 150 may have a short length so as not to be coupled with the cam 230. Is formed. In this case, the pin portion 151 of the temporary arm pivot 150 is preferably formed to have the same height as the rib 152.

FIG. 10 is a perspective view illustrating a part of the vehicle air conditioner according to the present embodiment, FIG. 11 is a partial front view of FIG. 10, and FIG. 12 is a sectional view taken along line A-A of FIG. 10.

10 to 12, the vehicle air conditioner is coupled to the air conditioning case 200, at least one or more doors 100, the one side of the door 100 is installed in the air conditioning case 200 (door) Cam 230 for controlling the rotation of the 100 and the actuator 300 is coupled to the other side of the door 100 to control the rotation of the door 100.

The air conditioning case 200 of the vehicle air conditioner includes a hole 210 through which the end 121 of the door shaft 120 can pass, and the door 100 of the door 100 so that the door 100 can be rotatably received. A first long hole 220 and a second long hole 260 are formed through which the arm pivot 140 or the temporary arm pivot 150 can pass. Similarly, a hole (not shown) through which the opposite end of the door shaft 120 may pass is formed at the opposite side of the air conditioning case 200, so that the door 100 may be coupled to the actuator 300.

The air conditioning case 200 is formed by penetrating the first and second long holes 220 and 260 into which the arm pivot 140 or the temporary arm pivot 150 may be fitted. 260 is formed with a predetermined curvature along a circular trajectory formed by the arm pivot 140 or the temporary arm pivot 150 when the door 100 rotates.

The first long hole 220 and the second long hole 260 are formed at positions symmetrical with respect to the hole 210, for example, so that the arm pivot 140 and the temporary arm pivot 150 are fitted at the same time. Accordingly, the arm pivot 140 and the temporary arm pivot 150 are moved within the section in which the first long hole 220 and the second long hole 260 are formed to limit the rotation radius of the door 100.

Thus, the ribs 142 formed on both sides of the pin portion 141 do not directly contact the pin portions 141 at both end jaws of the long hole, thereby increasing the rigidity of the pin portion 141 to increase durability. In addition, when the pin part 141 directly hits the end of the long hole during the strong rotation of the door 100, an unpleasant impact sound may occur. In this case, the rib 142 is integrally formed at both sides of the pin part 141. The lower side is wider and the upper side is narrower, so that the inclined surface of the rib 142 abuts on the end of the long hole, the impact sound can be offset. Also, the function and shape of the rib 142 of the arm pivot 140 may be equally applied to the temporary arm pivot 150 as the rib 152.

The first and second guide holes 220 and 260 are formed in the first and second long holes 220 and 260 to protrude to surround a part of the arm pivots 140 and 150. In this case, the first and second guide cases 240 and 250 may be formed to protrude up to the heights of the ribs 142 and 152 of the arm pivots 140 and 150.

The cam 230 may have the same shape and function as the cam 63 disclosed in the background. In this case, the first long hole 220 is formed in the direction of the cam 230 in the air conditioning case 200, and the second long hole 260 is formed on the opposite side of the first long hole 220 about the hole 210. Can be. That is, the operating radius of the cam slot 231 according to the rotation of the cam 230 may include the first long hole 220 and may not include the second long hole 260.

In addition, a cam slot 231 may be formed on an outer circumferential surface of the cam 230 to accommodate the pin portion 141 of the formed arm pivot 140, and the cam slot 231 may be rotated by the cam 230. Accordingly, the pin part 141 of the door 100 passing through the first long hole 220 may be restrained. In this case, when the pin part 141 passes through the second long hole 260, the cam slot 231 cannot accommodate the pin part 141 because the distance from the cam slot 231 of the cam 230 is far. (141) Not bound.

Therefore, when the arm pivot 140 of the door 100 is fitted into the first long hole 220 by the worker, and the temporary arm pivot 150 is fitted into the second long hole 260, the arm pivot 140 is assembled. The pin portion 141 excluding the rib 142 from the protruding outward from the first guide case 240 is inserted into the cam slot 231 of the cam 230, for example, according to the rotation of the cam 230 100 can be restrained and controlled.

On the contrary, the worker rotates the assembly direction of the door 100 by a predetermined angle so that the temporary arm pivot 150 of the door 100 is fitted into the first long hole 220, and the arm pivot 140 is formed. 2, when assembled to fit in the long hole 260, the pin portion 151 of the temporary arm pivot 150 except the rib 152 is shorter than the pin portion 141 of the arm pivot 140, the first guide case Since it does not protrude outward from 240 and is not fitted into the cam slot 231, it is not constrained by the rotation of the cam 230. Accordingly, the door 100 is not restricted by the rotation of the cam 230, and the independent rotation control by the actuator 300 is possible.

Therefore, the vehicle air conditioner according to the present embodiment may be assembled to the air conditioning case 200 by changing the direction of the door 100, so that the door 100 may be configured not to be constrained to the cam 230. When the 100 opens and closes the defrost discharge port, the actuator 300 may be combined with the actuator 300 to implement an ADS function. Accordingly, the vehicle air conditioner according to the present embodiment does not need to redesign the air conditioner case 200 to implement the ADS function, and can use the armless air conditioner case which is not provided with an arm or a lever, thereby significantly reducing the number of parts. At the same time, the ADS function can be implemented by independent control of the door.

Meanwhile, as shown in FIG. 12, the end 121 of the door 100 is rotatably inserted into the hole 210 of the air conditioning case 200, and the arm pivot 140 is slidable in the first long hole 220. The temporary arm pivot 150 is inserted into the second long hole 260 to be slidable. At this time, the first guide case 240 is formed to protrude up to the height of the rib 142 of the arm pivot 140, it can be seen that the pin portion 141 protrudes outside of the first guide case 240. . Similarly, the second guide case 250 is formed to protrude up to the height of the rib 152 of the temporary arm pivot 150, the temporary arm pivot 150 is configured to protrude to the outside of the second guide case 250 There is no Accordingly, the first and second guide cases 240 and 250 may be positioned to be symmetrical with respect to the hole 210 so that the door 100 may be rotated by an operator.
