Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a controller for controlling operating members such as a door and a fan motor of an automobile air conditioner.

(Prior Art) As shown in FIG. 5, the conventional controller 1 has a cooling mode (VENT), a head cold foot heat mode (B / L), and a heating mode (HEA).
T), defrost mode (DEF), inside air introduction (REC), outside air introduction (FRESH), and other control modes, temperature display, fan speed display (OFF, 1,2,3,4) It has a finisher 2 (hereinafter collectively referred to as an operation display) printed on the front surface, and the finisher 2 is fixed to a base 3.

A control lever 4 having a projecting tip is attached to the base 3 so as to select the operation display of the finisher 2. A cable 5 is connected to the rear end of the control lever 4, and the cable 5 is used for doors. The operating member (not shown) of the
No. 5,036) or a signal instructed by the control lever 4 to operate a negative pressure actuator, an electric actuator or the like to operate the operating member.

(Problems to be Solved by the Invention) However, the controller 1 thus configured has a large length from the finisher 2 to the rear end of the base 3 and is large.

In particular, since the place where the controller 1 is installed is an important place where various devices that can be operated by the driver are installed in the passenger compartment of the automobile, the size of the controller 1 can be minimized. desirable.

Therefore, recently, as shown in Japanese Utility Model Application Laid-Open No. 62-10,486, a circuit board having a circuit element for controlling air conditioning in a control box, and a connector board for electrically connecting the circuit element and an external device. It has been proposed that the circuit board is provided with switches, and switches are provided on the circuit board to electrically apply a control signal to the actuator.

This is a relatively small and thin type, but it also has a complicated structure because a circuit board, a connector board, etc. are provided between the tip of the control lever and the rear edge of the control box. In addition, since each substrate is not flattened enough and each substrate is made of a non-rigid material such as synthetic resin, there is a problem in strength, and it takes time to assemble and is expensive. It has become a thing.

The present invention has been made in view of the above-mentioned drawbacks and problems, and an object of the present invention is to provide an inexpensive air conditioner controller for an automobile that is extremely flat and has excellent strength.

[Structure of the Invention] (Means for Solving Problems) In order to achieve the above object, the present invention has a finisher having various operation indicators printed on the front surface thereof and a control lever for selecting the operation indicators of the finisher. In a controller of an air conditioner for a vehicle that operates various operating members corresponding to the operation display selected by the control lever, a recess for storing a slider is formed on the back side of the finisher. The finisher is attached to a flat enamel board, a slider slidably provided in the recess is connected to the control lever, and a brush is projected from the slider toward the enamel board so that the brush is placed on the enamel board. Select the provided terminal part, the back of the enamel board electrically connected to this terminal part The circuit elements is characterized in that so as to output an operation signal corresponding to the operation display.

(Operation) According to this structure, the terminal portion is provided on the rigid enamel board itself, and the finisher and the circuit element are attached around the enamel board, so that the number of parts and the number of assembling steps are significantly reduced. In addition, cost reduction and flattening can be achieved, and the strength is also excellent.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic exploded perspective view showing an embodiment of the present invention, and FIG.
The drawing is a sectional view showing an assembled state of the embodiment.

The controller 10 of this air conditioner for an automobile has a finisher 12 attached to the front side of a enamel board 11 with screws B and various circuit elements 13 (see FIG. 2) connected to the rear side of the enamel board 11. Is fixed to an instrument panel (not shown) or the like by a screw B.

On the front surface of the finisher 12, various modes and operation displays such as operation displays are printed, and as shown in FIG. 2, the cross-section has five recesses 15 which are open to the rear side.

A slider 16 is slidably installed in each recess 15, and a control lever 17 is attached to the slider 16.
The front end of the control lever 17 protrudes forward from the slit 18 formed in the recess 15, and a knob 19 is attached.

On the other hand, as shown in FIG. 3, the enamel substrate 11 is an iron plate 20 serving as a base material, and a transparent heat-resistant layer 21 such as glass is electrically glazed on the surface thereof.
Various terminal portions 22 are formed.

For example, the terminal portion 22a22b corresponding to the display of each mode of air conditioning or the inside / outside air selection mode is one in which the fixed terminal portion 22a22b is formed by printing copper in a predetermined pattern, and the set temperature display from low temperature to high temperature is displayed. The terminal portion 22c corresponding to is formed with the fixed terminal portion 22c by printing carbon in a predetermined pattern.

Further, a blower control device 23 for controlling the rotation speed of the blower fan 23
The terminal portion 22d is formed by printing the resistance member R on a heat-resistant plate 24 (having the same structure as the enamel board) in a predetermined pattern as shown in FIG. 22d may be directly connected, or this heat-resistant plate 24 may be installed in a portion where air flows and connected to the terminal portion 22d by a conductive wire. The tip of the terminal portion 22d protruding from the heat resistant plate 24 is fixed by caulking so as to protrude from the enamel substrate 11.

In forming the blow control device 23, the pattern of the resistance member R printed on the heat resistant plate 24 may be directly printed on the back surface of the enamel substrate 11. In this case, when a current flows through the resistance member R of the blower control device 23, Joule heat is generated, but since the heat-resistant plate 24 has extremely high heat dissipation, it is sufficiently cooled without blowing cooling air, There is no risk of problems.

In FIG. 4, reference numeral "M" is a fan motor, "K" is a slider, and "Cs" is a control switch.

In printing the terminal portions 22a, 22b, 22c, a paste containing copper or carbon is printed on the enamel substrate 11 and then baked. After this firing, the terminal 22
Then, d is fixed by caulking, and the circuit element 13 is connected to the printed terminal portion 22 on the back side to finish the enamel board 11.

A brush 25 protruding from the slider 16 slides on the terminal portion 22 printed on the enamel substrate 11, and a predetermined operation signal is applied by a circuit element 13 electrically connected to the terminal portion 22 to operate. The members are operated.

According to this structure, since the flat finisher 12 is attached to the front side and the circuit element 13 is directly connected to the back side around the rigid enamel board 11, the total thickness dimension l is extremely small. Become. Due to this ultra-thin structure, an extra space is created in the instrument panel. By using this extra space, for example, by increasing the size of the air duct, it is possible to increase the amount of air blow and to create a more comfortable air condition. Can be done.

Further, since the enamel substrate 11 having excellent strength is used, the strength of the controller itself can be increased. Moreover, since all of the enamel board 11 is printed or connected, the number of parts and the number of assembling steps are reduced, which is extremely advantageous in terms of cost.

[Effects of the Invention] As described above, according to the present invention, the terminal portion is printed on the enamel board, the circuit elements are connected, and the finisher is attached, so that the controller is extremely flat and excellent in strength. The cost can be reduced by reducing the number of points and the number of assembling steps.
