The present invention relates to a heater control switch assembly structure of a vehicle, and more particularly, to a heater control switch assembly structure of a vehicle capable of sharing the housing for the cable type heater control switch and the electric heater control switch.

The air conditioner of a vehicle selectively introduces the inside or outside air by the blower according to the opening / closing of the inside / outdoor switching doors, and cools the air by passing through the surface of the evaporator in the air conditioning case, or by operating the temperature control door. After passing through the heater core selectively and heating, cold air or warm air is branched into each vent according to the opening and closing selection of the vent doors and discharged to each part of the car interior to remove frost while cooling and heating the car interior.

In the air conditioner as described above, the mixing ratio of the air passing through the evaporator and the air passing through the heater core is controlled by a temperature control door, and the air flowing toward the vents is installed in each vent. Controlled by vent doors. For example, a vent mode for discharging to the passenger's upper body, a foot mode for discharging to the passenger's foot, a bi-level mode for discharging simultaneously to the passenger's upper body and to the foot, and a defrost mode for discharging frost or mist by discharging the vehicle window do.

In order to set any of these air conditioning modes, a controller is installed in the center fascia panel of the vehicle, and the controller covers the front opening of the housing and switches having a housing inserted and fixed inside the center fascia panel. A control cover is provided.

The switches include a wind direction control switch for turning the vent doors in the vent, a heater control switch (or temperature control switch) for controlling the temperature in the vehicle cabin by adjusting the opening degree of the temperature control door, and rotation of the blower fan. It is generally composed of air volume control switch for controlling water and air / heating switch for operating a cooling / heating cycle. In the case of the heater control switch, the cable type and the electric type are large depending on the operation method. Can be divided.

As shown in FIG. 1, a cable heater control switch, which is generally known, has a gear 20 in which one end of a shaft is rotatably supported by a boss 11 formed from an inner bottom surface of the housing 10, and the gear ( A lever gear 30 rotatably installed around the boss 11 and connected to the temperature control door side and the cable 40 so as to be engaged with the boss 20, and a gear 20 protruding outside the housing 10. It comprises a knob 50 coupled to the shaft end of the). The teeth of the gear 20 are beveled and the teeth of the lever gear 30 are arced.

In addition, the knob 50 may be rotated by the driver by protruding out of the control cover of the controller. On the other hand, since the structure of the cable-type wind direction control switch for operating the vent door also has a structure corresponding to the above-described heater control switch, a description thereof will be omitted.

According to the conventional cable type heater control switch configured as described above, as the gear 20 is rotated by the rotation of the knob 50, the lever gear 30 engaged therein pivots in an arc shape, so that the lever gear ( Rotation of the temperature control door is controlled as the cable 40 connected to 30 is stretched in conjunction with each other.

On the other hand, conventionally known electric heater control switch, as shown in Figure 2, the case 70 surrounding a portion of the knob shaft 76 rotatably installed on the printed circuit board 75 inside the housing 60 It is provided. The case 70 is fixed by a screw 62 to a fixing hole 61 formed at one side of the housing 60, and the knob 50 protruding to the outside of the housing 60 at an end of the knob shaft 76. Is combined. On the other hand, the printed circuit board 75 is electrically connected to the actuator for driving the temperature control door and the signal output from the printed circuit board 75 in accordance with the rotation of the knob shaft 76 according to the operation of the knob 50 A locking body (not shown) for changing the distance between the knob shaft 76 and the printed circuit board 75 is interposed. Since the electric wind direction control switch also has a structure corresponding to the electric heater control switch, a detailed description thereof will be omitted.

According to the conventional electric heater control switch configured as described above, by the rotation of the knob shaft 76 according to the operation of the knob 50, the contact position of the locking body with respect to the printed circuit board 75 is changed to the position Accordingly, an electrical signal is generated differently to change the operating voltage for the actuator for controlling the temperature control door.

However, the above-described conventional heater control switches are difficult to apply the same housing because they are different from each other depending on whether the components installed inside the housing are cable type or electric type.

That is, when it is desired to mount the case 70 constituting the electric heater control switch on the cable housing 10, the bottom of the case 70 interferes with the boss 11 protruding from the bottom surface of the cable housing 10. In addition, the cable-type housing 10 is not provided with a fixing hole 61 for fixing the case 70 employed in the motorized type, so that the cable type housing 10 has a housing 10 that is adopted in the motorized type. The electric switch case 70 cannot be installed.

On the contrary, when the gear 20 and the lever gear 30 constituting the cable type heater control switch are mounted on the motorized housing 60, the boss capable of supporting the gear 20 and the lever gear 30 is supported. Not only 11 is not provided in the motorized housing 60, but also the motorized housing 60 is not provided with a structure for connecting the cable 40 to the lever gear 30. Can not be mounted.

Therefore, since the conventional heater control switch must have different housings 10 and 60 according to its operation, the manufacturing cost increases and the specification becomes complicated.

The present invention has been made to solve the above problems, and provides a heater control switch assembly structure of a vehicle that can share the housing of the heater control switch operated via a cable, and the housing of the heater control switch electrically operated. For the purpose.

In order to achieve the above object, the present invention comprises a housing and a knob; The knob is coupled to the gear shaft of the cable type unit having a gear selectively installed in the housing and a lever gear meshed with the gear and connected to the temperature control door side via a cable, or selectively installed in the housing. A vehicle coupled to a knob shaft of an electric unit having a case, a printed circuit board electrically connected to an actuator on a temperature control door, and a knob shaft rotatably installed on the case to change an output signal of the printed circuit board according to rotation. In the heater control switch assembly structure of:

The housing includes a boss for rotatably supporting one end of the gear shaft and serving as a center of rotation of the lever gear, and at least one fixing hole for fixing the case;

When the case is installed in the housing, a stepped surface is formed at the bottom of the case so that the bottom of the case does not interfere with the boss.

When the case is installed in the housing, it is preferable that a part far from the housing bottom of the step surface of the case bottom is supported at the top of the boss.

Therefore, when configuring a cable type heater control switch, a gear shaft and a lever gear may be installed in the housing, the knob may be coupled to the gear shaft, and a cable may be connected to the lever gear. In addition, when the electric heater control switch is configured, a printed circuit board, a case and a knob shaft are installed in the housing, a knob is coupled to the knob shaft, and the printed circuit board and the temperature control door side actuator are electrically connected. Just do it.

It must be interpreted to mean meanings and concepts.

3 to 6, the housing 110 applied to the heater control switch assembly structure of the vehicle of the present invention, as well as the cable type heater control switch can be used as it is without changing the shape of the electric heater control switch. . That is, the housing 110 is commonly used for the cable type heater control switch and the electric heater control switch.

The cable type heater control switch includes a gear unit having a gear 120 and a lever gear 130 engaged with the gear 120 and connected to the cable 140 connected to the temperature control door side. According to the present invention, the boss 111 is installed on the bottom surface of the housing 110 so that the housing 110 can be used in a cable type heater control switch. The boss 111 is preferably formed in the same structure as in the housing applied to the conventional cable type heater control switch.

The boss 111 may not only rotatably support one end of the gear 120 shaft disposed horizontally with respect to the housing 110, but also the cable through the housing 110 with the boss 111 as the center of rotation. It is formed to rotatably support the lever gear 130 to which the 140 is connected. The teeth of the gear 120 are beveled and the teeth of the lever gear 130 corresponding thereto are arced. Accordingly, the lever gear 130 may be rotated around the boss 111 as the gear 120 rotates, and the lever gear 130 is preferably formed in a semicircular shape. In addition, the knob 150 is coupled to an end of the shaft of the gear 120 to protrude to the outside of the control cover 180 coupled to the front of the housing 110 so that the driver can operate the knob 150.

On the other hand, according to the present invention, the housing 110, as described above, as well as the cable type heater control switch can be used in common without changing the shape of the electric heater control switch.

That is, in the case of the electric heater control switch, instead of the above-described cable type unit, the case 170, a printed circuit board 175 electrically connected to the temperature control door side actuator), and the case 170 are rotatably installed. An electric unit having a knob shaft 176 that changes an output signal of the printed circuit board 175 according to rotation is installed in the housing 110, and the case 170 can be fixed to the housing 110. At least one fixing hole 112 is formed in a predetermined place of the housing 110 in order to make it possible. According to the present invention, two fixing holes 112 and 112 are formed.

In addition, the fixing hole 112 should be formed in a position that does not interfere with the components applied to the cable type heater control switch, and is also formed in the same structure as in the housing applied to the conventional type cable type heater control switch. In this case, it is preferable that the fixing part formed in the case 170 in correspondence with the fixing hole 112 is also formed in the same manner as in the prior art. If the formation position of the fixing hole 112 is changed, the fixing part formed in the case 170 should also be changed accordingly, and in any case, the housing 110 may be connected to both the cable type heater control switch and the electric heater control switch. It can be applied as is.

In the case of configuring the electric heater control switch, the boss 111 may interfere with the case 170, which may be a problem. In the present invention, the bottom part 171 of the case 170 is connected to the boss 111 to solve the problem. The step is formed in the face so as not to interfere.

That is, as shown in FIGS. 5 and 6, when the bottom portion 171 is formed as a stepped surface such that a part of the bottom portion 171 of the case 170 is supported by the top portion 111a of the boss 111 as described above. When fixing the case 170 to the housing 110, the boss 111 does not interfere with the case 170, but rather, the case 170 is disposed by the boss 111. ), There is an advantage that can be stably supported. That is, a part far from the bottom of the housing 110 of the stepped surface is supported by the upper end 111a of the boss 111. The case 170 may be fixed by fastening the fixing part and the fixing hole 112 formed in the case 170 with the screw 113 while being supported by the boss 111.

When configuring a cable type heater control switch, the lever gear 130 is rotatably inserted into the boss 111 of the housing 110, and then the gear 120 is disposed to engage the teeth of the lever gear 130. At the same time, one end of the shaft of the gear 120 is fitted to the boss 111 to be rotatably coupled. Then, the knob 150 is coupled to the other end of the shaft of the gear 120, and then the cable 140 connected to the temperature control door side is connected to the lever gear 130. At this time, no component is coupled or interfered with the fixing hole 112 of the housing 110, and thus, a switch may be assembled according to the same process as in the prior art.

On the other hand, in the case of configuring the electric heater control switch, the housing 170 so that the bottom portion 171 is supported on the upper end 111a of the boss 111 by combining the case 170 combined with the printed circuit board 175 and the knob shaft 176. Arranged at 110 and then fixing the fixing part of the case 170 to the fixing hole 112 by using the screw 113. Then, the printed circuit board 175 and the temperature control door-side actuator is electrically connected. In this case, not only the case 170 and the boss 111 do not interfere, but rather, the bottom 171 of the case 170 is formed in a stepped surface such that the bottom 171 of the case 170 is supported by the upper end 111 a of the boss 111. Therefore, there is an advantage that the case 170 can be stably supported inside the housing 110.
