Description

  The present invention relates to a door lever structure of a vehicle air conditioner that is applied to a door that opens and closes an air passage such as a heater and cooling unit of a vehicle.

  Conventionally, of the door lever structure of a vehicle air conditioner, the positioning function at the time of assembly is enhanced by forming a positioning guide on the wall surface of the casing and integrally forming a positioning pin on the door lever via the neck. Is known (for example, see Patent Document 1).

In the above-described conventional door lever structure, at the time of assembly, the positioning guide formed on the wall surface of the casing and the positioning pin formed on the door lever are engaged, and the relative rotation position between the control door main body fixed to the door shaft and the door lever is set. After that, the positioning pin is cut off.
Japanese Patent No. 3202043

  However, in the conventional door lever structure of a vehicle air conditioner, since the positioning pin is formed integrally with the door lever through the neck, the door lever itself is enlarged and the positioning pin is removed after assembly. There was a problem of requiring work to be performed.

  The present invention has been made paying attention to the above-mentioned problem, and at the time of assembling the door lever, it does not cause an increase in the size of the door lever or requires work in a later process, and easily achieves two types of assembly setting patterns. An object of the present invention is to provide a door lever structure for a vehicle air conditioner.

To achieve the above object, according to the present invention, a door that opens and closes an air flow path, a door shaft that is attached to the door and is rotatably supported by an air conditioning case, and a door lever set at a door shaft end of the door shaft In a door lever structure of a vehicle air conditioner equipped with
As a pattern for assembling and setting the door lever with respect to the door shaft end portion, a first setting pattern that engages with a fixing pin provided in the air conditioning case and fixes the door opening degree, and a fixing pin provided in the air conditioning case And a second setting pattern that can change the door opening without engaging with
The fixing pin is set at a position outside a lever operating range that does not hinder the actual rotation of the door lever when the door opening degree is changed by selecting the second setting pattern.

Therefore, in the door lever structure of the vehicle air conditioner according to the present invention, when the door lever is assembled to the door shaft end portion, the door lever is fixed by engaging with the fixing pin provided in the air conditioning case. One of two setting patterns, that is, a setting pattern and a second setting pattern that can change the door opening degree without engaging with a fixed pin provided in the air conditioning case, can be selected.
Since the fixed pin is set at a position outside the lever operating range that does not hinder the actual rotation of the door lever, the fixed pin does not interfere with the door opening change operation.
For example, when a pin structure is formed on the side of the door lever, the size of the door lever is increased because the pin structure is attached to a part different from the lever body. In the second setting pattern, the pin structure attached to a part different from the lever main body hinders the actual rotation of the door lever. Therefore, it is necessary to cut the pin structure after assembly.
On the other hand, in the present invention, by adopting a configuration in which the fixing pin is set at the position outside the lever operating range on the air conditioning case side, the door lever does not increase in size, and it is excised in a later process. There is no need for work.
As a result, when assembling the door lever, it is possible to easily achieve two types of assembling setting patterns without causing an increase in the size of the door lever or requiring a work in a later process.

The differential door lever 16 is set to a door shaft end 21 a that protrudes out of the air conditioning case 1 of the differential door shaft 21.

As a pattern for assembling and setting the door levers 15 and 16 with respect to the door shaft end portions 20a and 21a, the door lever opening degree is engaged with a first fixing pin 17 and a second fixing pin 18 provided in the air conditioning case 1. The first opening pattern is fixed (see the two-dot chain line in FIG. 3), and the door opening can be changed without engaging the first fixing pin 17 and the second fixing pin 18 provided in the air conditioning case 1. “Second setting pattern” (see the solid line in FIG. 3).
The “first setting pattern” fixes the vent door 11 to the fully open position and the differential door 13 to the fully closed position, as indicated by the one-dot chain line in FIG.
As shown by the solid line in FIG. 2, the “second setting pattern” indicates that the door levers 15 and 16 are interlocked with each other by the rotation of the L-shaped link 22 driven by the door actuator. The opening degree of the door can be changed.

  The first fixing pin 17 is a pin that is provided in the air conditioning case 1 and that engages and fixes the vent door lever 15 by selecting the “first setting pattern”. When the door opening is changed by selecting the “second setting pattern”, it is outside the lever operating range (the range from the solid line position to the two-dot chain line position in FIG. 2) that does not hinder the actual rotation of the vent door lever 15. Set to position.

  The second fixing pin 18 is a pin which is provided in the air conditioning case 1 and engages and fixes the differential door lever 16 by selecting “first setting pattern”. When the door opening is changed by selecting the “second setting pattern”, it is outside the lever operating range (range from the solid line position to the two-dot chain line position in FIG. 2) that does not hinder the actual rotation of the differential door lever 16. Set to position.

The L-shaped link 22 is a link that is rotatably attached to the link boss 19 of the air conditioning case 1 and that connects the vent door lever 15 and the differential door lever 16 to the positions of both ends.
A door actuator (not shown) is connected to the L-shaped link 22, and when the “second setting pattern” is selected, the door opening degree of the vent door 11 and the differential door 13 is controlled by controlling the link rotation angle. Is done.

  In the door lever structure of the first embodiment, the “first setting pattern” includes the vent door lever 15 and the differential door lever 16 on the back surface, and engages with the first fixing pin 17 and the second fixing pin 18 provided in the air conditioning case 1, The door opening degree is fixed by fitting in the rotational direction with respect to the door shaft end portions 20a and 21a. Further, the “second setting pattern” has the vent door lever 15 and the differential door lever 16 as surfaces, and does not engage with the first fixing pin 17 and the second fixing pin 18 provided in the air conditioning case 1, and the door shaft end portions 20a and 21a. The door opening degree can be changed by fitting in the rotational direction.

  That is, a rotation fitting structure with a square fitting surface is provided in the mounting portion between the door shaft end portions 20a and 21a and the door levers 15 and 16 (see FIG. 6), and the lever when the “first setting pattern” is selected. The surface along the line that bisects the angle formed by the setting position and the lever setting position when the “second setting pattern” is selected is used as the fitting surface. That is, the angles θ1, θ1 ′ formed by the center axis connecting the both end support portions of the door levers 15 and 16 at the lever setting position when the “first setting pattern” is selected and the fitting surface, and the “second setting pattern” Are set to the same angle (θ1 = θ2, θ1 ′ = θ2) formed by the central axis connecting both end support portions of the door levers 15 and 16 at the lever setting position and the fitting surface. ')is doing. With this setting, the same first door pattern 15 and differential door lever 16 are used without changing the door lever between the “first setting pattern” and the “second setting pattern”.

When the “second setting pattern” is selected, the vent door lever 15 and the differential door lever 16 are moved to the L-shape by fitting both pins 22a and 22b into the first pin groove 15a and the second pin groove 16a, respectively. When connected to the link 22 and the “first setting pattern” is selected, the vent door lever 15 and the differential door lever 16 are fixed by fitting the fixing pins 17 and 18 into the pin grooves 15a and 16a, respectively. .

  Next, the operation will be described.

[When selecting the first setting pattern]
When the “first setting pattern” is selected as a pattern for assembling and setting the vent door lever 15 and the differential door lever 16 with respect to the door shaft end portions 20a and 21a, the vent door lever 15 and the differential door lever 16 are Is assembled and set.
(a) The vent door 11 is set to the fully open position.
(b) Turn the vent door lever 15 upside down to the back.
(c) The bent door lever 15 turned upside down while keeping the bent door lever 15 in the fully open position is fitted to the door shaft end 20a in the rotational direction, and the first fixed pin provided with the first pin groove 15a in the air conditioning case 1 17 is attached by engaging.
(d) The differential door 13 is set to the fully closed position.
(e) Turn the differential door lever 16 over to the back.
(f) The second fixed pin provided with the second pin groove 16a provided in the air-conditioning case 1 while the differential door lever 16 turned upside down while keeping the differential door 13 in the fully closed position is fitted in the rotational direction with respect to the door shaft end portion 21a. 18 is attached by engaging.

  With the above procedure, as shown in FIG. 4, a “first setting pattern” is realized in which the vent door 11 is fixed at the fully open position and the differential door 13 is fixed at the fully closed position. In this “first setting pattern”, the L-shaped link 22 is not used.

[When selecting the second setting pattern]
When the “second setting pattern” is selected as a pattern for assembling and setting the vent door lever 15 and the differential door lever 16 with respect to the door shaft end portions 20a and 21a, the vent door lever 15 and the differential door lever 16 are Is assembled and set.
(a) The vent door 11 is set to the fully open position.
(b) The vent door lever 15 is the surface.
(c) The vent door lever 15 having a regular surface while keeping the vent door lever 15 in the fully open position is engaged with the door shaft end portion 20a in the rotation direction without engaging the first fixing pin 17.
(d) The differential door 13 is set to the fully closed position.
(e) The differential door lever 16 is the surface.
(f) The differential door lever 16 having a regular surface while keeping the differential door 13 in the fully closed position is engaged with the door shaft end 21a in the rotational direction without engaging the second fixing pin 18.
(g) The L-shaped link 22 is attached to the link boss 19 and the pins 22a and 22b of the L-shaped link 22 are fitted into the first pin groove 15a of the vent door lever 15 and the second pin groove 16a of the differential door lever 16, respectively.

By the above procedure, as shown in FIG. 5, the door opening between the vent door 15 and the differential door 16 is changed by the interlocking of the door levers 15 and 16 by the rotation of the L-shaped link 22 driven by the door actuator. The “second setting pattern” that can be realized is realized.
When the door opening is changed by selecting the “second setting pattern”, the first fixing pin 17 is set to a position outside the lever operating range of the vent door lever 15, so that the actual rotation of the vent door lever 15 is performed. I do not disturb. Further, since the second fixing pin 18 is set at a position outside the lever operating range of the differential door lever 16, the actual rotation of the differential door lever 16 is not hindered.

[When sharing units with different mode performance]
The on-board air conditioning unit has a heater and cooling unit with mode performance that can select vent mode, bi-level mode, foot mode, differential mode, etc., and a cooling unit with mode performance (vent mode only) that allows only mode selection on the cooler side. There is.

  When setting two types of heaters and cooling units and cooling units for these two different mode performances, there are few components to be shared and they are separate from design to manufacturing, which is disadvantageous in terms of cost. Become.

On the other hand, in the case of the first embodiment, the “first setting pattern” is selected, the vent door 11 is fully opened and the differential door 13 is fully closed and fixed, so that a cooling unit can be obtained. By selecting “2 setting pattern” and allowing the vent door 11 and the differential door 13 to control the opening of the door, a heater and cooling unit can be obtained.
Thus, in the case of Example 1, two types of air conditioning units can be shared. In this case, the components are the same, and except for the selection of the setting pattern, it is the same from design to manufacturing. This is advantageous in terms of cost.

[When assembling the door through the temporary fixing process]
When assembling each door of the heater & cooling unit into the air conditioning case, if the air conditioning case is split while the door is freely movable, the door opening will change during the mating and the door will be Incorporated with a deviation from the normal door opening. Also, if there is a deviation in the opening of the built-in door, the air-conditioning control will be greatly affected, and it will be necessary to perform difficult and time-consuming work to assemble the door, such as removing the built-in one and re-installing it. It was.

  On the other hand, in the case of Example 1, the “first setting pattern” is selected, the vent door lever 15 and the differential door lever 16 are turned over, the vent door 11 is temporarily fixed in the fully open state, and the differential door 13 is temporarily fixed in the fully closed state. In addition, if the divided air conditioning case 1 is fitted, the opening of the vent door 11 and the opening of the differential door 13 do not deviate from the normal opening, and the air conditioning case is divided relatively easily. 1 fitting operation can be performed. After the air conditioning case 1 is fitted, the “second setting pattern” is selected, and the vent door 11 and the differential door 13 can be controlled by opening the vent door lever 15 and the differential door lever 16 to the front side. Can be.

  As described above, in the case of the first embodiment, the “first setting pattern” is used as temporary fixing of the vent door 11 and the differential door 13, so that it is relatively easy to divide while achieving a high assembling accuracy that maintains a normal door opening degree. Thus, the fitting operation of the air conditioning case 1 can be performed.

Next, the effect will be described.
In the door lever structure of the heater and cooling unit of the first embodiment, the effects listed below can be obtained.

  (1) Doors 11 and 13 for opening and closing the air flow path, door shafts 20 and 21 attached to the air-conditioning case 1 while being attached to the doors 11 and 13, and door shaft ends of the door shafts 20 and 21 In the door lever structure of the heater and cooling unit provided with the door levers 15 and 16 set in the portions 20a and 21a, the air conditioning is used as a pattern for assembling and setting the door levers 15 and 16 with respect to the door shaft end portions 20a and 21a. “First setting pattern” that engages with the fixing pins 17 and 18 provided in the case 1 and fixes the door opening degree, and the door opening degree does not engage with the fixing pins 17 and 18 provided in the air conditioning case 1. A changeable “second setting pattern”, and the fixing pins 17, 18 change the door opening of the door levers 15, 16 when the door opening is changed by the selection of the “second setting pattern”. Since it is set at a position outside the lever operating range that does not interfere with actual rotation, there is no need to increase the size of the door levers 15 and 16 when the door levers 15 and 16 are assembled, and there is no need for work in a later process. The assembly setting pattern can be achieved.

  (2) The “first setting pattern” has the door levers 15 and 16 on the back side, engages with the fixing pins 17 and 18 provided on the air conditioning case 1, and rotates in the rotational direction with respect to the door shaft end portions 20 a and 21 a. The door opening degree is fixed by fitting, and the "second setting pattern" has the door levers 15 and 16 as the surface, does not engage with the fixing pins 17 and 18 provided in the air conditioning case 1, and Since the door opening degree can be changed by fitting in the rotational direction with respect to 20a and 21a, it is the same without preparing another door lever for selecting the “first setting pattern” and the “second setting pattern”. Two assembly setting patterns can be realized while using the door levers 15 and 16.
