Description

[Detailed description of the invention] This invention is installed under the dash board of the driver's seat of a car to control the air conditioner, such as switching between ventilation and heating, adjusting the heating temperature, adjusting the amount of outside air introduced, and adjusting the amount of air blown out. This device relates to a control device for an automobile air conditioner that is equipped with a lever for operating the lever, and was devised for the purpose of obtaining the device that is easy to manufacture, assemble, and attach to the vehicle body. The base for attaching lamps, etc., is made of integrally molded synthetic resin with high rigidity.

Conventionally, this type of device required a separate plate for mounting the lever, a lamp chamber for illuminating a display board indicating the operating status of the lever, etc., and then assembling these parts to obtain a control device.
There were drawbacks such as inefficient manufacturing, assembly, and installation in automobiles.

Furthermore, if the mounting plate is not sufficiently rigid to withstand the pressing force that accompanies the rotation of the lever, the mounting plate may be deformed, resulting in a vibration phenomenon in which the click does not work.

The present invention provides a control device for an automobile air conditioner that can eliminate this drawback.

Hereinafter, the present invention will be explained with reference to drawings showing embodiments.

Figures 1 to 5 show the shape of the base, Figure 6 shows the shape of the display board,
Figures 7 and 8 show the shape of the lever, and Figure 9 shows how it is attached to the vehicle body.

The base made of synthetic resin has four lever shafts 2 formed on both sides of the rear of the board 1 (if the number of levers is reduced due to design conditions, the number of lever shafts 2 is reduced).

) A lamp chamber 3 and two mounting pieces 4 are formed in the front part, and one fixing retaining piece 5 is formed in the side part.

Three of the four lever shafts 2 are hollow cylindrical, have slots 6 at their ends, and are formed to have the same shape and size.

The remaining shaft 2 is slightly shorter and has no slots.

At the front of the substrate 1, a groove-shaped lamp chamber 3 extending from side to side is formed integrally with the substrate 1.

A flange-shaped front plate 7 is formed around the lamp chamber 3.
A display plate 9 is attached between the upper and lower ridges 8 and 80 of the front plate 1.

The inner surface of the groove-shaped lamp chamber 3 is inclined so that the center part of the groove is deeper, and a socket 11 for mounting a light bulb 10 is attached to the deepest part.

Four horizontal holes 13 through which levers 12 (described later) are inserted are bored in the front plate T at the left, right, top and bottom of the lamp chamber 3.

Around each horizontal hole 13, in order to prevent light leakage from the horizontal hole 13, a ridge 14 having a height equal to the thickness of the display panel 9 is provided with a shape M,
has been done.

The display board 9 has characters, symbols, etc. drawn on it indicating the air conditioner control status of each lever 12, and the Togi ridge 1 attached to the front board I.
A horizontal hole 15 into which 4 is fitted is bored.

Therefore, the lever 12 projects forward through the horizontal hole 15 of the display board 9.

On the top surface of the board behind the socket 11 is a duct 1 for passing the conductor.
6 is formed so that a conductive wire connected to the socket 11 is brought out from the rear end of the base.

On the upper and lower surfaces of the substrate 1, there are arcuate protrusions 1 centered around each axis 2.
7, 17, and a triangular recess 1 that stably engages the protrusion 18a of the spring piece 18 attached to each lever 12.
Form several pieces 7a.

The spring piece 18 is fixed by inserting bent portions 18b and 18c at the ends into small holes (not shown) provided in the lever 12, and protrudes from the front surface of the display board 9 through the horizontal holes 13 and 15. When the lever 12 is rotated around the shaft 2, the recess 17a
the lever 12 by elastically riding over the recess or engaging the recess.
This forms a click mechanism that allows the device to stand still in a stable manner.

The lever 12 is moved by the horizontal hole 1 of the front plate T due to the reaction force of the spring piece 18.
3, so in order to reduce the friction with the iron wire, the part that contacts the iron wire is punched out to form a contact surface 19 as shown in FIGS. 7 and 8.

A shaft hole 20 is formed in the rear end of the lever 12, and the shaft 2 is fitted into the shaft hole 20. A snap ring is engaged with an annular groove (not shown) formed at the end of the shaft 2, so that the lever 12 is fixed to the shaft. Make sure you don't go beyond 2.

The lever that fits on the short shaft 2 is inserted into and drives a switch (not shown) installed on the board 1, and since the shaft 2 is structured so that it cannot be removed, a snap ring is not required. necessary, and no annular groove is formed.

One end of a wire (not shown) for opening and closing the air conditioner is latched to a lever 12 other than the lever fitted to the short shaft 2 for operating the switch described above.

As shown in FIG. 9, the control device of the present invention constructed as described above is mounted by connecting the mounting piece 4 with the bolt 21 to the bracket 23 provided below the dash board of the automobile driver's seat, and removing the retaining piece 5 from the vehicle body. It is inserted immovably in the vertical direction into a protruding and fixed two-pronged bracket (not shown), and is supported at three points and attached to the vehicle body.

Thereafter, the cover 22 is attached to the vehicle body to cover the front surface beautifully.

Since the control device for an automobile air conditioner according to the present invention is constructed as described above, it can be assembled by attaching the lever 12, display plate 9, switch, etc. to the substrate 1 integrally molded with synthetic resin and the lamp chamber 3. Compared to the conventional method where the board and lamp chamber are manufactured separately and combined, assembly work is significantly easier.The single board 1 is reinforced by the lamp chamber 3 at the front and the duct 16 at the center. This increases rigidity, especially in the part of the front plate I that receives the strongest force when levers are operated. It doesn't give a feeling.

In addition, in the past, in order to compensate for the weakness of the base of the joint type, the board, etc. was made thicker, and the metal fittings used to attach it to the car body were made strong and heavy. Since such a sturdy installation does not require any metal fittings, it has a significant weight reduction effect, and is effective as a control device for a lightweight automobile air conditioner that is easy to manufacture and assemble.
