  However, in the conventional air-conditioning control device, in order to secure the amount of movement of the inner wire necessary to operate the temperature adjustment door of the air-conditioning device, it may not be possible to cope with it unless the lever is lengthened. There is a problem in that the air conditioning control device becomes longer in depth and the air conditioning control device becomes larger.

  In general, the wires are routed while avoiding interference with other parts from the air conditioning control device provided on the center panel of the vehicle to the air conditioning device provided on the back side of the glove box, but the wire is bent. If this happens, the lever's operating force will be affected, so it is necessary to route the wires so that they do not bend as much as possible. Therefore, there is a case where it is necessary to take measures such as deforming the glove box so that the wire is not bent as much as possible. In this case, there is a problem that the capacity of the glove box is reduced.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an air conditioning control device capable of reducing the size and facilitating the arrangement of cables.

In order to achieve the above object, the invention according to claim 1 is an air conditioning control device for controlling an air conditioner by operating an operation knob of an operation member held movably on a base.

The operation member is slidably held on the base, the operation knob is provided on the front surface of the operation member, and the first gear portion is provided on the rear surface.
A pulley is rotatably supported on the base, and a second gear portion that meshes with the first gear portion of the operation member is formed on the pulley.
Wrap the inner cable connected to the air conditioner around the pulley,
A rail-shaped concave portion extending in the lateral direction is formed on one of the base and the operation member, and a rail-shaped convex portion that is engaged with the rail-shaped concave portion in the front-rear direction is formed on the other,
The base is integrally provided with an elastically deformable stopper having a restricting surface for restricting the operation range of the operation member in which the engagement state between the rail-shaped recess and the rail-shaped protrusion is maintained.

It is characterized by having comprised.

  According to the first aspect of the present invention, when the user operates the operation knob and slides the operation member with respect to the base, the slide operation force of the operation knob causes the first gear portion of the operation member and the second gear of the pulley. Therefore, the pulley is rotated and the cable wound around the pulley is pushed and pulled, so that the air conditioner connected to the cable is controlled. And since a lever is not used in such a configuration, it is necessary to ensure the amount of cable movement necessary to operate the temperature adjusting door of the air conditioner without increasing the length of the lever as in the prior art. As a result, the depth of the air conditioning control device can be reduced to reduce the size of the air conditioning control device.

Even if the cable wound around the pulley is bent slightly, the effect on the operating force of the operation knob is negligible. Therefore, measures such as deforming the glove box to avoid interference with the cable can be taken. It becomes unnecessary and the occurrence of problems such as a decrease in the capacity of the glove box is prevented.

It can be easily meshed at the meshing position, and the assembling property of the air conditioning control device is improved.

According to the invention described in claim 3 , the base and the operating member cannot be assembled at the position where the rail-shaped concave portion and the rail-shaped convex portion overlap in the front-rear direction, so that the rail-shaped concave portion and the rail-shaped convex portion do not overlap in the front-rear direction. In the lateral direction in which both are shifted, the amount of shift is regulated to a predetermined value (a length range within one pitch of the gears of the first and second gear portions) by the base positioning portion. Therefore, the operation member cannot be assembled to the base unless it is a predetermined assembly position positioned by the base positioning portion, and the first gear portion and the second gear portion are securely engaged at the predetermined engagement position. Can be assembled.

According to the invention described in claim 4, the stopper portion provided on the base allows the operation member to move into the operation range by elastic deformation and is elastic after the operation member is once inserted into the operation range.

The light is emitted from the illumination window 3a of the knob 3 to the outside. As shown in FIGS. 3 and 4, a power supply connector 14 is attached to the upper part of the back surface of the printed board 11.

  As shown in FIGS. 1 and 4, a pulley housing portion 6A and an outer cable fixing portion 6B are integrally formed on the rear side of the base 6, and the bottom surface of the pulley housing portion 6A is shown in FIG. In this manner, a cylindrical support shaft portion 6j is erected, and an annular peripheral wall 6k (see FIG. 6) is erected around the columnar shaft portion 6j. As shown in FIGS. 4 and 6, engaging claws 6j1 that can be elastically deformed are integrally formed at three locations on the outer periphery of the support shaft portion 6j.

  Thus, the pulley 15 is rotatably accommodated in the pulley accommodating portion 6A of the base 6. Here, as shown in FIG. 6, the pulley 15 is integrally formed into an inner and outer double cylinder shape, and the inner cylinder 15A is fitted into the support shaft portion 6j of the base 6, and the inner periphery of the outer cylinder 15B is fitted. A flange-like protrusion 15a formed on the inner periphery of the lower end of the inner cylinder 15A is formed on the outer periphery of the support shaft portion 6j by being rotatably supported by the base 6 by being fitted to the outer periphery of the peripheral wall 6k of the base 6. By engaging the three engaging claws 6j1, the pulley 15 is prevented from coming off from the support shaft portion 6j. 4 and 5, the pulley 15 has a positioning pin insertion hole 15b.

  Further, a cable guide groove 15c is formed on the outer periphery of the upper end of the inner cylinder 15A of the pulley 15 as shown in FIG. 1, and an inner cable 16a of the cable 16 is wound around the cable guide groove 15c. Here, the cable 16 includes an outer cable 16b and the inner cable 15a slidably passed through the outer cable 16b. A part of the inner cable 16a is formed on the top of the pulley 15. The pulley 15 is fitted into the V-shaped inner cable fixing portion 15d and pressed by the V-shaped protrusion 18a of the inner cable fixing piece 18 fixed to the pulley 15 by a screw (see FIGS. 4 and 5) 17. It is fixed to. The inner cable 16a is wound around a pulley provided on the air conditioner (not shown), and the rotation of the pulley 15 is transmitted to the temperature adjustment door, which opens and closes the desired temperature. Adjustments are made.

  As shown in FIGS. 4 and 5, the outer cable 16 b is fitted in the outer cable fixing portion 6 </ b> B formed in the lateral direction on the base 6, and the outer cable fixing piece 20 attached to the outer cable fixing portion 6 </ b> B with a screw 19. And is fixed to the inner cable fixing portion 6B of the base 6.

  Further, as shown in FIGS. 1, 4 and 5, a sector gear-like second gear portion 15e is formed at the lower outer periphery of the pulley 15, and is formed on the rear surface of the second gear portion 15e and the operation member 7.

  In the air-conditioning control apparatus 1 configured as described above, when the user operates the operation knob 3 and slides the operation member 7 left and right, the left and right movements are the first gear portion 7a of the operation member 7 and the pulley 15. The pulley 15 is rotated through the second gear portion 15e of the pulley 15 so that the pulley 15 rotates, and the inner cable 16a wound around the cable guide groove 15c of the pulley 15 is pushed and pulled, so that the temperature of the air conditioner is increased. The adjustment door is opened and closed, and thereby a desired temperature adjustment is made. In this case, since the opening / closing member 7 is formed in a rectangular plate shape that is long in the lateral direction, even if it is slid left and right, the knob insertion hole 2a of the front panel 2 is blocked by the operation member 7 and the appearance is improved. Leakage of illumination light from the knob insertion hole 2a is prevented.

  Next, the assembly procedure of the air-conditioning control apparatus 1 according to the present invention will be described below with reference to FIGS.

  FIG. 8 is a plan sectional view showing a state before the operation member is assembled into the base, FIG. 9A is a plan sectional view showing a state in the middle of assembling the operation member into the base, and FIG. 9B is an operation member in the same state. FIG. 10A is a plan view showing a state in which the operating member is assembled into the base and moved to the right end, and FIG. 10B shows the operating member and the base in the same state. FIG. 11A is a plan sectional view showing a state in which the operating member is incorporated in the base and moved to the left end, and FIG. 11B is a diagram showing the relationship between the operating member and the base in the same state. It is a front view which shows a combined state.

  First, as shown in FIG. 8, the pulley 15 is attached to the support shaft portion 6j of the base 6, and the positioning pin insertion hole 15b formed in the pulley 15 and the positioning pin insertion hole (not shown) formed in the base 6 are cured. A tool pin is inserted to position the pulley 15 at a predetermined position with respect to the base 6. Then, the printed board 11 is vertically attached to the base 6 with screws or the like.

  Next, the operating member 7 is slidably attached to the base 6 in the following manner.

  That is, in the state shown in FIG. 8, if the rail-shaped concave portion 7d of the operating member 7 and the rail-shaped convex portion 6b of the base 6 overlap in the front-rear direction, the operating member 7 cannot be assembled to the base 6. The operating member 7 is positioned at a lateral position where the right end of the convex portion 6b and the left end of the rail-shaped concave portion 7d of the operating member 7 are slightly shifted. Specifically, the contact portion 7c (see FIG. 7) which is the side surface of the click mechanism housing portion 7A formed on the rear surface of the operation member 7 is positioned on the positioning portion 6i (see FIG. 9) of the base 6 as shown in FIG. 1), the end surfaces of the operation member 7 facing the rail-shaped concave portion 7d and the rail-shaped convex portion 6b of the base 6 are opposed to each other in the lateral direction of the first gear portion 7a and the second gear portion 15e. The operation member 7 is positioned laterally with respect to the base 6 so as to be displaced within a length range within one pitch of the gear.

  As described above, when the operating member 7 is positioned laterally with respect to the base 6, the operating member 7 is moved rearward (in the direction of the arrow in FIG. 8). When the operating member 7 is pushed rearward toward the base 6, the operating portion 7f of the operating member 7 presses the stopper portion 6g of the base 6 as shown in FIG. Elastically deforms and bends backward. In this state, when the end surfaces of the rail-shaped concave portion 7d of the operating member 7 and the rail-shaped convex portion 6b of the base 6 are opposed to each other and the operating member 7 is moved to the left side, the rail-shaped convex portion 6b is formed in the rail-shaped concave portion 7d. The operation member 7 is slidably held on the base 6 and the engagement between the operation portion 7f of the operation member 7 and the stopper portion 6g of the base 6 is released. Then, the stopper portion 6g of the base 6 is elastically restored and returned to the original position as shown in FIG.

  As described above, the operation member 7 cannot be assembled to the base 6 unless it is in the above-described assembly position. By assembling the operation member 7 to the base 6 at the assembly position, the first gear of the operation member 7 is assembled. The portion 7a and the second gear portion 15e of the pulley 15 can be reliably engaged at a predetermined engagement position.

  Next, the operation knob 3 is moved to the center position in the left-right direction of the knob insertion hole 2a of the front panel 2, and the inner cable 16a of the cable 16 is wound around the cable guide groove 15c of the pulley 15 as shown in FIG. The inner cable 16 a is fixed to the pulley 15 using the inner cable fixing piece 18, and the outer cable 16 b is fixed to the base 6 using the outer cable fixing piece 20.

  Finally, when the front panel 2 is fixed to the front side of the base 6 with screws, the assembly of the air conditioning control device 1 is completed. When the air conditioning control device 1 is assembled in this way, the operation member 7f of the operation member 7 contacts the restriction surface 6g1 of the stopper portion 6g of the base 6 as shown in FIG. 11 and the movement of the operation member 7 in the left direction is restricted by the operation portion 7f of the operation member 7 coming into contact with the stopper portion 6f of the base 6 as shown in FIG. Therefore, the movement range of the operation member 7 is restricted within a predetermined operation range, and the fitting between the rail-shaped concave portion 7d of the operation member 7 and the rail-shaped convex portion 6b of the base 6 is maintained within this operation range. This prevents the operating member 7 from falling off the base 6.

  As described above, in the air conditioning control device 1 according to the present invention, when the user operates the operation knob 3 and slides the operation member 7 with respect to the base 6, the slide operation force of the operation knob 3 is applied to the operation member 7. Since the rotational force is transmitted to the pulley 15 through the first gear portion 7a and the second gear portion 15e of the pulley 15, the pulley 15 rotates and the inner cable 16a wound around the pulley 15 is pushed and pulled. The air conditioner connected to the inner cable 16a is controlled. Since the lever is not used in such a configuration, the amount of movement of the inner cable 16a necessary for operating the temperature adjusting door of the air conditioner is secured without increasing the length of the lever as in the prior art. Accordingly, the depth of the air conditioning control device 1 can be reduced, and the air conditioning control device 1 can be downsized.

  In addition, since a two-wire cable is used, even if the cable 16 wound around the pulley 15 is slightly bent, the influence on the operation force of the operation knob 3 is negligible. Therefore, it is not necessary to take measures such as deforming the glove box in order to avoid interference with the device, and it is possible to prevent problems such as a decrease in the capacity of the glove box.

  Furthermore, in the air-conditioning control apparatus 1 according to the present invention, the operation knob 3 and the first gear portion 7a are disposed apart from each other in the vertical direction on the operation member 7, and therefore the LED 13 for illumination is disposed on the back side of the operation knob 3. The operation knob 3 can be illuminated with a simple configuration without using a light guide lens or the like. Then, the first gear portion 7 a of the operation member 7 and the second gear portion 15 e of the pulley 15 can be engaged with each other through the through hole 6 e formed in the base 6.

  In the air conditioning control device 1 according to the present invention, since the positioning portion 6i for positioning the operation member 7 provided with the first gear portion 7a at a predetermined assembly position is provided in the base 6, the first gear portion 7a and The second gear portion 15e can be easily meshed at a predetermined meshing position, and the assembling property of the air conditioning control device 1 is improved.

  And in the assembly | attachment of the air-conditioning control apparatus 1 which concerns on this invention, the assembly | attachment of the base 6 and the operation member 7 cannot be performed in the position where the rail-shaped recessed part 7d of the operation member 7 and the rail-shaped convex part 6b of the base 6 overlap in the front-back direction. The rail-shaped concave portion 7d and the rail-shaped convex portion 6b are shifted so that the rail-shaped convex portion 6b does not overlap in the front-rear direction, and the amount of shift in the lateral direction is set to a predetermined value (first and second gear portions 7a, 7a, 15e gear length range within one pitch). Accordingly, the operation member 7 cannot be assembled to the base 6 unless it is a predetermined assembly position positioned by the positioning portion 6 i of the base 6, and the first gear portion 7 a of the operation member 7 and the second gear portion of the pulley 15. 15e can be securely engaged with each other at a predetermined engagement position and assembled.

  Further, in the assembly of the air conditioning control device 1 according to the present invention, the stopper portion 6g provided on the base 6 allows the operation member 7 to move within the operation range by elastic deformation, and the operation member 7 is within the operation range. In order to prevent the operation member 7 from moving out of the operation range after being inserted once, the stopper portion of another member is fixed to the base 6 after the operation member 7 is mounted on the base 6. Thus, the structure of the air conditioning control device 1 is simplified and the assemblability is improved.
