Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a control unit in an automobile air conditioner.

Generally, an automobile's air conditioning system has a control unit located approximately at the bottom center of the instrument panel, and the air conditioning inside the vehicle is controlled by operating the air control lever, temp control lever, fan switch, etc. provided on this unit. It has become.

However, cars are usually manufactured that are equipped with only a heater unit, and therefore, in order to create an air conditioner with a built-in so-called Tara, an air conditioner unit must be additionally installed at a dealership.

When such an air conditioner unit is installed, it goes without saying that a switch (generally a compressor switch, referred to as an A/C switch) for controlling the operation of this unit must be added to the control unit. It is necessary to provide

For this reason, conventionally, as shown in Fig. 1, a space for installing the A/0 switch is secured in a part of the front panel 1a of the control unit 1, and when the air conditioner is an option, this space is used for installing the A/0 switch. 0 switch 2 is newly installed.

In addition, like the control unit 3 shown in FIG.
An A/C switch 5 is also provided in association with the air control lever 4, and the switch is configured to operate when the lever 4 is in a predetermined position.

However, in such a configuration, A/0 switch 2
, 5, it is necessary to once remove the control units 1 and 3 from the instrument panel, and to add more switches, it is also necessary to connect the switches and the control units.

Furthermore, in the former control unit 1, it is necessary to make a hole for installing the A/0 switch in the front panel la, and in the latter control unit 3, the front panel is changed to the front panel with the new position indicated on the lever 4. Needs to be replaced.

Therefore, when working on air conditioner options,
The reality is that the above-mentioned troublesome work is required in addition to the complicated work of compressors, condensers, cooling units, etc., and this is one of the causes of a large increase in the number of work hours.

This invention was made in view of the above, and a connector to be connected to a compressor switch is connected to the control unit in advance, and this connector is attached to a blind cover that closes an additional hole formed at the planned switch mounting position. By having a configuration in which they are mated together, the switch can be installed extremely easily without the need to add or remove the control unit from the instrument panel, and without the need for wiring or drilling, making it an option for air conditioners. The purpose of the present invention is to provide a control unit for an air conditioner that is efficient in reducing work man-hours.

Hereinafter, this invention will be explained based on illustrations.

Note that this invention, like the conventional example shown in FIG.
This applies to models in which a switch is newly installed on a panel (front panel or instrument 1 panel).

FIG. 3 is a front view of the instrument panel 10, and FIG. 4 is a perspective view of the main parts.

As shown in the figure, the control unit 11 of the present invention has a main body 12 attached to the lower center of the instrument panel 10, and a predetermined control unit 11 is operated by manual operation of an air control lever 13, a balance control lever 14, a fan switch 15, etc. It is designed to control air conditioning.

In this embodiment, the control unit main body 12
A rectangular switch mounting hole 16 is formed in the instrument panel 10 at such a position that the A/C switch is disposed on the right side of the instrument panel.

Here, the A/0 switch 11, as shown in FIG.
A push button 19 is arranged on the front surface of the rectangular resin body 18, and protrusions 21, 21 are provided on the upper and lower rear of the front flange 20.
By pressing the switch from the front of the switch mounting hole 16, the flange 20 and protrusion 21 are removed as shown in FIG.
, 21 are fitted and attached with the instrument panel 10 sandwiched between them.

Also, on the rear surface of the A/C switch 11, there are a plurality of male ends -7.
22 is formed protrudingly.

On the other hand, a harness 23 to be connected to the A/C switch when necessary is connected to the control unit main body 12, regardless of the presence or absence of an air conditioner.
A connector 25 having a female terminal 24 that fits into the male terminal 22 of the A/C switch is connected to the tip of the A/C switch.

This connector 25 is connected to the switch mounting hole 16.
On the back surface of the instrument panel, as shown in FIG. 6, the cover 26 is fitted and supported on the back surface of a blind cover 26 that is fitted into the switch mounting hole 16 from the front.

That is, the blind lid 26 has tongue pieces 27, 2 protruding from the upper and lower parts of the back surface.
7 is elastically engaged with and fitted into the upper and lower edges of the switch mounting hole 16, and the protrusion 28 integrally formed on the back side is formed in the same shape as the male end 722 of the A/0 switch 11). The female terminal 24 of the connector 25 is fitted therein.

According to the above configuration, when an air conditioner is not installed, the blind cover 26 is fitted into the switch mounting hole 16 as shown in FIG. 6 to close the switch mounting hole 16, and
The connector 25 is fitted and supported on the back surface of the blind lid 26.

Therefore, the beauty of the instrument does not deteriorate due to the opening of the switch mounting hole 16, and the connector 25 can be prevented from moving loosely, thereby preventing problems such as cracking.

When installing an air conditioner, if the blind cover 26 fitted in the switch mounting hole 16 is removed forward, the connector 25 can be inserted into the switch mounting hole 16 together with the blind cover 26.
from the connector 25 and then from the connector 25 the blind lid 2
6, and instead fit the male terminal 22 of the A/C switch 17 into the female terminal 24 to connect both terminals, and then push the A/C switch 17 into the mounting hole 16, as shown in Fig. 5. Thus, the A/C switch 17 can be fitted and supported in the mounting hole 16.

Therefore, A/C associated with additional air conditioner equipment
When installing the switch, it is not necessary to remove the control unit main body 12 from the instrument panel 10, and it is also possible to omit the work of forming a switch mounting hole or replacing the front panel. This makes the work extremely simple and reduces the overall man-hours required for additional equipment work.

Here, the A/C switch may be configured to be attached to the front panel position of the control unit. In this case, a switch mounting hole is formed in the front panel and this hole is covered with a blind cover. Just do it.

As explained above, the air conditioner control unit of the present invention has a configuration in which the connector to which the compressor switch is connected is connected in advance, and this connector is fitted and supported by the blind cover that closes the mounting hole. Therefore, when installing the switch that accompanies the additional equipment C of the air conditioner, there is an effect that it is not necessary to remove the control unit from the instrument panel, and the number of work steps can be greatly reduced.
