Background technique

Generally, a vehicle air conditioner includes a cooling system for cooling the vehicle interior and a heating system for heating the vehicle interior. the

The cooling system is cooled by making the refrigerant circulated into the compressor pass through the condenser, receiving dryer, expansion valve and evaporator under the operation of the compressor, and exchange heat with the blowing air passing through the surface of the evaporator under the action of the blower. Converts blowing air into cold air and discharges the cold air into the vehicle interior to cool the vehicle interior. the

In addition, the heating system introduces cooling water into the heater core, and heats the interior of the vehicle by exchanging heat between the cooling water and the air blown from the blower. the

There are three types of car air conditioners. the

As one of these three types, there is a three-piece air conditioner in which a blower unit, an evaporator unit, and a heater unit are independently constituted, but this three-piece air conditioner has several problems, namely: Occupies a larger vehicle interior space and has lower productivity. the

Therefore, an air conditioner with a compact size is required to improve the utilization efficiency of the vehicle interior space. In response to this need, a semi-center mounting type (semi-center mounting type) air conditioner in which an evaporator unit and a heater unit are integrally mounted, or in which a blower unit, an evaporator unit, and a heater unit are all integrally mounted, has recently been used more and more. Center mounted air conditioner. the

FIG. 1 shows an embodiment of a semi-centre-mounted air conditioner according to the prior art, in which the blower unit is not shown. the

The vehicle air conditioner 1 shown in FIG. 1 includes: an air conditioner housing 10 having defrosting openings 11, 11, The face opening 12 and the floor opening 13; a blower (not shown) connected to the air inflow port of the air conditioner case 10 to blow indoor air or outdoor air; the evaporator 2 and the heater core embedded in the air conditioner case 10 3; and a temperature regulating door 20, which is used to control the mixing amount of the cold air passing through the evaporator 2 and the hot air passing through the heater core 3. the

Here, the temperature regulating door 20 is classified into a flat type, a dome type, a sliding type, and the like. Fig. 1 shows the situation of an embodiment using a sliding type temperature regulating door. the

The temperature regulating door 20 is slidably installed on the sliding grooves 15 formed on the inner side walls of the air conditioner casing 10, and includes: a sliding door 21 having a gear part 21a formed on one side; and a gear shaft 22 which can Rotatably engaged to through holes (not shown) formed on both side walls of the air conditioner housing 10 , and has a gear portion 22 a meshing with a gear portion 21 a of the sliding door 21 to operate the sliding door 21 . the

The temperature regulating door 20 controls the opening of the outlet of the cold air passage P1 and the opening of the inlet of the hot air passage P2, thereby controlling the mixing amount of the cold air and the hot air. the

According to the vehicular air conditioner 1 constructed as described above, when operating in the maximum cooling mode, the temperature regulating door 20 opens the cool air passage P1 and closes the hot air passage P2. In addition, when operating in the maximum heating mode, the temperature regulating door 20 closes the cold air passage P1 and opens the hot air passage P2. the

Therefore, when operating in the maximum cooling mode, air blown from a blower (not shown) is converted into cool air after passing through the surface of the evaporator 2 while exchanging heat with the refrigerant flowing inside the evaporator 2 , flows toward the mixing chamber (MC) through the cold air passage P1, and is discharged into the vehicle interior through the orifice opened in the predetermined air conditioning mode (ventilation mode, floor mode, defrost mode, dual-stage mode, or hybrid mode) , thereby cooling the interior of the vehicle. the

In addition, when operating in the maximum heating mode, the blown air is converted into hot air by heat exchange with cooling water flowing inside the heater core 3 while passing through the heater core 3 via the hot air passage P2, toward mixing The air flows through the cavity and is discharged into the vehicle interior through an orifice that is opened in a predetermined air conditioning mode, thereby heating the vehicle interior. the

In addition, when operating in not the maximum cooling mode but the general cooling mode (ie, 1/2 cooling mode), as shown in FIG. Inlet of air channel P2. Accordingly, the cool air passing through the evaporator 2 and the hot air passing through the heater core 3 flow toward the mixing chamber (MC) and mix with each other, and then are discharged into the vehicle interior through the orifice opened in a predetermined air conditioning mode. the

Meanwhile, in order to improve the assembly performance of the temperature-regulating door 20 (including the sliding door and the gear shaft) assembled to the air-conditioning housing 10, as shown in FIG. 2 , Japanese Patent Application Laid-Open No. 11-240321 discloses a temperature-regulating door , wherein a frame 25 is formed at one side of the sliding door 21 and the gear shaft 22 is fixed to the frame 25 such that the sliding door 21 and the gear shaft 22 are temporarily assembled with each other before being assembled to the air conditioner case 10 . the

However, if the gear shaft 22 is temporarily assembled to the frame 25 of the sliding door 21 and the temporarily assembled sliding door 21 and frame 25 are assembled to the air conditioner casing 10, the assembling performance can be improved, but another problem is caused, that is, due to The frame 25 must be additionally formed on the sliding door 21, and thus the manufacturing cost increases. the

In addition, since the weight of the sliding door 21 is increased by the frame 25 , a load is generated on an actuator (not shown) that rotates the gear shaft 22 to operate the sliding door 21 . the

Detailed ways

Reference will now be made in detail to preferred embodiments of the present invention with reference to the accompanying drawings. the

The same components as in the prior art have the same reference numerals as in the prior art. the

3 is an exploded perspective view of a temperature regulating door of a vehicle air conditioner according to a first preferred embodiment of the present invention. FIG. 4 is a perspective view showing a state in which a gear shaft and a sliding door of FIG. A perspective view of a state where a temperature regulating door according to a preferred embodiment is mounted on an air conditioner casing, and FIG. 6 is a state showing that a setting pin is disconnected after the temperature regulating door according to the first preferred embodiment is assembled to an air conditioner casing stereogram. the

Referring to Fig. 1, the vehicle air conditioner 1 according to the present invention comprises: an air conditioner housing 10, in which a cold air channel P1 and a hot air channel P2 are formed; an evaporator 2 embedded in the cold air channel P1 and an embedded heat the heater core 3 in the air passage P2 ; and the temperature regulating door 100 for controlling the amount of cool air passing through the evaporator 2 and the amount of hot air passing through the heater core 3 . the

A blower (not shown) is installed at the air inlet of the air conditioner case 10 to blow indoor air or outdoor air into the air conditioner case 10 . the

In addition, at the air outlet of the air conditioner case 10 are sequentially formed: a defroster opening 11 for discharging air toward the front window of the vehicle, a face opening 12 for discharging air toward the passenger's face, and a face opening 12 for discharging air toward the passenger's face. Floor openings 13 for air discharge at the foot of the foot. These openings are opened and closed and their openings are adjusted by the mode doors 11a, 12a and 13a, respectively. the

The heater core 3 is installed on the hot air passage P2 of the air conditioner casing 10, and the evaporator 2 is installed on the cold air passage P1 of the air conditioner casing 10, that is, the air flow close to the air conditioner casing 10 on the upstream side of the hot air passage P2 Entrance. the

Meanwhile, the air conditioner case 10 is divided into right and left sides to allow mode doors 11a, 12a, and 13a, a temperature adjustment door 100, and the like to be installed therein. the

In addition, the temperature-adjusting door 100 is a sliding door, and includes: a sliding door 110 slidably mounted on sliding grooves 15 formed on both inner wall surfaces of the air conditioner housing 10, and gears are formed on one side thereof. part 111; and a gear shaft 120 located in front of the sliding door 110, which is rotatably engaged to the through holes 16 formed on both side walls of the air conditioner housing 10, and has a gear part 111 meshing with the sliding door 110 to operate sliding The gear part 121 of the door 110 . the

Here, since the gear portion 111 is formed at both end portions of the sliding door 110, the gear portion 121 is also formed at a position corresponding to the gear portion 111 formed at both end portions of the sliding door 110. the

In addition, the sliding door 110 has supporting pins 119 protruding at edges of both ends thereof, and the supporting pins 119 are inserted and engaged to the sliding grooves 15 so that the sliding door 110 is slidably mounted on both sides formed on the air conditioner case 10. On the sliding groove 15 on the inner wall surface. the

Therefore, when the gear shaft 120 is rotated by an actuator (not shown) installed on the outer surface of the air conditioner case 10, the sliding door 110 geared with the gear shaft 120 is slidably operated to control the cool air passage. The opening degree of the outlet of P1 and the opening degree of the inlet of the hot air channel P2 can control the mixing amount of cold air and hot air. the

The gear shaft 120 and the sliding door 110 are temporarily assembled with each other before being mounted to the air conditioner case 10 to ensure the engaged position of the gear shaft 120 and the sliding door 110 . After the temporarily assembled gear shaft 120 and the sliding door 110 are mounted on the air conditioner case 10, the temporarily assembled gear shaft and sliding door may be released. For this, the gear shaft 120 has a set pin 125 and the sliding door 110 has support members 115 respectively having pin holes 116 for engaging with the set pin 125 . The reason is to prevent deviation between the gear shaft 120 and the sliding door 110 when assembling the gear shaft 120 and the sliding door 110 to the air conditioner casing 10 . the

Here, it is preferable that two support members 115 protrude toward the inside of the gear portion 111 of the sliding door 110 , but two or more support members 115 may be formed. the

In addition, setting pins 125 formed on the gear shaft 120 are respectively formed at positions corresponding to the support members 115 and are integrally connected with the gear shaft 120 through a connection portion 126 . the

Here, it is preferable to form the connection parts 126 to be weak so that they can be disconnected even with a small force. the

Meanwhile, as shown in FIG. 4, when the setting pin 125 and the supporting member 115 are engaged with each other, the gear shaft 120 is engaged with the sliding door 110 in a state where it deviates from the center of the sliding door 110, while the gear portion of the gear shaft 120 121 and the gear portion 111 of the sliding door 110 are not meshed with each other. the

Here, it is preferable that the gear portion 121 of the gear shaft 120 and the gear portion 111 of the sliding door 110 are not meshed with each other when the set pin 125 and the support member 115 are engaged with each other, but the present invention is not limited to the above. That is, when the setting pin 125 and the support member 115 are engaged with each other, the gear shaft 120 and the sliding door 110 are not engaged with each other at the normal position (a state in which each gear portion is fully meshed), but when the gear shaft 120 is moved from the sliding door Joining is performed in a state where the centers of 110 are shifted. In this case, the gear parts 111 and 121 are partially meshed with each other. the

For example, only about 1/3 of the gear portion 121 of the gear shaft 120 meshes with the gear portion 111 of the sliding door 110 . the

The setting pin 125 and the supporting member 115 are only used to temporarily assemble the gear shaft 120 and the sliding door 110 to each other, and after the gear shaft 120 and the sliding door 110 are finally assembled to the air conditioner casing 10, the gear shaft 120 and the sliding door 110 are released. The temporary assembly state between to operate the sliding door 110. the

Therefore, when the temperature-regulating door 100 temporarily assembled before the gear portion 121 of the gear shaft 120 and the gear portion 111 of the sliding door 110 are meshed with each other is finally assembled to the air-conditioning case 10 , during the complete assembly of the separated air-conditioning case 10 , the deviated gear shaft 120 is positioned at a normal position by the pressure generated when the air conditioner casing 10 is fully assembled. During the above process, the gear parts 111 and 121 are fully meshed, while the set pin 125 is disconnected and separated from the gear shaft 120 . the

Of course, the setting pin 125 disconnected and detached from the gear shaft 120 continues to maintain the state where it is inserted and engaged to the pin hole 116 of the support member 115 . the

Meanwhile, the gear portion 121 of the gear shaft 120 and the gear portion 111 of the sliding door 110 are not meshed with each other in a state where the setting pin 125 and the supporting member 115 are engaged with each other. Therefore, when the sliding door 110 and the gear shaft 120 are finally assembled to the air conditioner casing 10 in the above state, in order to assemble correctly and easily, the gear part 111 of the sliding door 110 rotates the central gear part of the gear part 111 toward a The side extends with a guide gear 112 formed on one side thereof. the

The guide gear 112 may be selectively formed in an inward direction or an outward direction of the gear part 111 of the sliding door 110 . the

That is, the guide gear 112 supports the gear portion 121 of the gear shaft 120 in an meshed state when the gear portions 111 and 121 are not meshed with each other, guides the gear portion 121 of the gear shaft 120 so that the gear portion 120 ends on the gear shaft 120. The gear portion 111 of the sliding door 110 is correctly and smoothly engaged with the air conditioner case 10 when assembled. the

The method of assembling the temperature regulating door of the air conditioner according to the first preferred embodiment of the present invention will be described below. the

First, before assembling the gear shaft 120 and the sliding door 110 to the air conditioner case 10, the setting pin 125 of the gear shaft 120 is inserted and engaged into the pin hole 116 formed on the support member 115 of the sliding door 110, thereby setting the The gear shaft 120 and the sliding door 110 are temporarily assembled with each other. the

In this case, the gear shaft 120 is engaged with the sliding door 110 in a state deviated from the center of the sliding door 110 , and the gear portion 121 of the gear shaft 120 and the gear portion 111 of the sliding door 110 are not meshed with each other. the

After that, the provisionally assembled gear shaft 120 and sliding door 110 are assembled to the air conditioner case 10 . That is to say, when one end of the gear shaft 120 is fully inserted into the through hole 16 of the air conditioner housing 10 on one side at first and then the air conditioner housing 10 on the other side is assembled, the gear shaft 120 deviated relative to the sliding door 110 is in a normal position. , and the other end of the gear shaft 120 is fully inserted and engaged to the through hole 16 of the air conditioner case 10 on the other side. Meanwhile, the support pin 119 of the sliding door 110 is seated and engaged to the sliding groove 15 formed on the inner wall surface of the air conditioner case 10 . the

In this case, while the gear shaft 120 is in the normal position, the setting pin 125 of the gear shaft 120 is disconnected and separated from the gear shaft 120 while the gear portion 121 of the gear shaft 120 is fully engaged with the gear portion 111 of the sliding door 110 , so as to fully assemble the temperature regulating door 100. the

7 is an exploded perspective view of a temperature regulating door of a vehicle air conditioner according to a second preferred embodiment of the present invention. FIG. 8 is a perspective view showing a state in which the gear shaft and the sliding door of FIG. The second preferred embodiment is a perspective view of the state where the temporarily assembled temperature-regulating door is assembled to the air-conditioning case, and FIG. A perspective view of a component with its pin holes slidably separated. In the second preferred embodiment, the same description as the first preferred embodiment will be omitted. the

As shown in these figures, in the second preferred embodiment, in order to temporarily assemble the gear shaft 120 and the sliding door 110 to each other before they are assembled to the air-conditioning case 10 and to remove them temporarily after they are assembled to the air-conditioning case 10 In an assembled state, the gear shaft 120 has a setting pin 125, the sliding door 110 has a support member 115 having pin holes 116 for engaging the setting pin 125, and each pin hole 116 is formed with an opening on one side thereof 117, so that the setting pin 125 can be slidably separated from the pin hole 116 along the insertion direction of the pin hole 116. the

In this case, the cutout portion formed by the opening 117 on the pin hole 116 has a predetermined elasticity. the

In addition, when the gear shaft 120 and the sliding door 110 are temporarily assembled with each other, the setting pin 125 is inserted and engaged into the pin hole 116 of the supporting member 115, in this case, in order to make the setting pin 125 only when an external force greater than a predetermined level is applied. The set pins 125 are slidably separated from the pin holes 116 in the insertion direction of the pin holes 116 , and each set pin 125 has a protrusion 127 formed on an end portion or a tapered surface 128 formed on the outer peripheral surface of the set pin 125 . the

That is, the setting pin 125 is inserted and engaged into the pin hole 116 of the support member 115 to temporarily assemble the gear shaft 120 and the sliding door 110 with each other, in this case, since The protrusion 127 of the set pin 125 or the tapered surface 128 formed on the outer peripheral surface of the set pin 125 makes the set pin 125 no longer inserted into the pin hole 116 due to being blocked by the pin hole 116, so that the temporarily assembled state can be maintained. Here, as long as no external force greater than a predetermined level is applied to the gear shaft 120 or the sliding door 110, the set pin 125 is not separated from the pin hole 116 in the insertion direction of the pin hole 116, but continues to be temporarily assembled. the

However, when an external force greater than a predetermined level is applied to the gear shaft 120 or the sliding door 110 , that is, when the temporarily assembled gear shaft 120 and the sliding door 110 are assembled to the air conditioner case 10 , the sliding force toward the gear shaft 120 or the sliding door 110 The door 110 applies an external force greater than a predetermined level while completely assembling the divided air conditioner case 10 . In this case, the set pin 125 is slidably separated from the pin hole 116 in the insertion direction of the pin hole 116 . the

Here, the connecting portion 126 for connecting the setting pin 125 to the gear shaft 120 slides along the opening 117 of the support member 115, and during the sliding of the setting pin 125 in the pin hole 116, the protrusion formed on the setting pin 125 127 or tapered surface 128 passes through pin hole 116 and widens pin hole 116 at the same time. the

As described above, after the tentatively assembled gear shaft 120 and sliding door 110 are completely assembled to the air conditioner casing, the setting pin 125 is separated from the pin hole 116, so that the gear shaft 120 and the sliding door 110 can be moved without interference and noise. to operate. the

In addition, the sliding door 110 further includes a guide 118 protruding from one side of the support member 115 to guide and insert the setting pin 125 into the pin hole 116 correctly and easily. the

Therefore, when the gear shaft 120 and the sliding door 110 are temporarily assembled with each other, first, the two setting pins 125 formed on the gear shaft 120 and spaced apart from each other by a predetermined interval are respectively seated on the seating grooves 118a of the guide 118 toward the pins. The hole 116 is slidably movable. Then, the set pin 125 can be correctly and easily inserted and engaged to the pin hole 116 .

In addition, when the tentatively assembled gear shaft 120 and sliding door 110 are assembled to the air conditioner case 10, in order to correctly position, place and engage the support pins 119 formed at both ends of the sliding door 110 to the air conditioner body formed on the On the sliding groove 15 on the inner wall surface of the housing 10 , the air conditioner housing 10 has a guide plate 17 protruding from the inner wall surface to guide the support pin 119 to the sliding groove 15 . Here, the guide plate 17 has a slope formed on a side thereof to smoothly guide the support pin 119 toward the slide groove 15 . the

Preferably, a total of two guide plates 17 are formed on both sides of the through hole 16 of the air conditioner case 10 and are spaced apart from each other by a predetermined distance to allow the gear shaft 120 to be installed. the

In addition, it is preferable that among the gear teeth 121a and 121b formed on the gear part 121 of the gear shaft 120, the tooth tip diameter of the gear tooth 121b meshing with the gears formed at both ends of the gear part 111 of the sliding door 110 larger than the addendum diameter of the other tooth 121a. the

That is, the gear shaft 120 is rotated clockwise or counterclockwise with respect to a position where the gear shaft is initially assembled to the sliding door 110 , thereby operating the sliding door 110 . Here, when the gear shaft 120 is rotated to the end position in the clockwise or counterclockwise direction so that the sliding door 110 is located at the upper dead center or the lower dead center, due to the gear portion 121 of the gear shaft 120 and the gear portion 111 of the sliding door 110 The gear meshing level is lowered, so the gear tooth 121b formed at the end portion of the gear shaft 120 in the clockwise direction or the counterclockwise direction is formed to have a tooth tip diameter larger than that of the other gear tooth 121a, thereby being different from that formed at the sliding door 110. The gears at both ends of the gear part 111 are firmly meshed. the

In addition, in the first preferred embodiment, the guide gear 112 is formed in an outward direction of the gear portion 111 of the sliding door 110 , but is formed in an inward direction of the gear portion 111 of the sliding door 110 in the second preferred embodiment. As described above, the guide gear 112 may be formed at a plurality of positions, for example, in an inward direction or an outward direction of the gear part 111 of the sliding door 110 . the

Meanwhile, it is preferable that the outer surface of the sliding door 110 is coated with rubber to improve sealing. the

In addition, the sliding door 110 is formed with closing plates 113 on opposing faces of the gear parts 111 formed at both ends thereof so as to close the sides of the respective gear parts 111 . One of the closing plates 113 has an open slot 113a. Here, it is preferable that the groove 113 a is located at a position corresponding to the gear portion 121 of the gear shaft 120 and has a curved surface larger than the outer diameter of the gear portion 121 . the

Therefore, since only one of the closing plates 113 has the groove 113a, the gear shaft 120 is assembled to the sliding door 110 in only one direction to prevent wrong assembly. the

The method of assembling the temperature regulating door of the air conditioner according to the second preferred embodiment of the present invention will be described below. the

First, before assembling the gear shaft 120 and the sliding door 110 to the air conditioner case 10, the setting pin 125 of the gear shaft 120 is inserted and engaged into the pin hole 116 formed on the support member 115 of the sliding door 110, thereby setting the The gear shaft 120 and the sliding door 110 are temporarily assembled with each other. the

In this case, the gear shaft 120 is engaged with the sliding door 110 in a state deviated from the center of the sliding door 110 , and the gear portion 121 of the gear shaft 120 and the gear portion 111 of the sliding door 110 are not meshed with each other. the

After that, the provisionally assembled gear shaft 120 and sliding door 110 are assembled to the air conditioner case 10 . That is to say, when one end of the gear shaft 120 is fully inserted into the through hole 16 of the air conditioner housing 10 on one side at first and then the air conditioner housing 10 on the other side is assembled, the gear shaft 120 deviated relative to the sliding door 110 is in a normal position. , and the other end of the gear shaft 120 is fully inserted and engaged to the through hole 16 of the air conditioner case 10 on the other side. Meanwhile, the support pin 119 of the sliding door 110 is seated and engaged to the sliding groove 15 formed on the inner wall surface of the air conditioner case 10 . the

In this case, while the gear shaft 120 is in the normal position, the setting pin 125 of the gear shaft 120 is slidably separated along the insertion direction of the pin hole 116 of the support member 115 formed on the sliding door 110, and the gear shaft 120 The gear part 121 of the sliding door 110 is completely meshed with the gear part 111 of the sliding door 110, so that the temperature regulating door 100 is completely assembled. the
