BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a vehicle air conditioner installed inside an instrument panel in a vehicle compartment.

[0002]

2. Description of the Related Art Conventionally, an air conditioner for supplying conditioned air into a passenger compartment is generally arranged between an instrument panel and a dash panel of a vehicle. When mounting this air conditioner on a vehicle, a method of mounting the air conditioner by itself on the dash panel and then mounting the instrument panel on the vehicle assembly line is used. In this method, the air conditioner is arranged at a predetermined position while inserting its heater pipe or the like into the installation hole formed in the dash panel, and is fixed to the dash panel with a fastening member. The on-board robot transfers the vehicle from the door opening of the vehicle body into the vehicle interior, and similarly fixes it to the dash panel or the like.

[0003]

However, in the above-mentioned conventional air conditioner mounting method, since the air conditioner and the instrument panel are separately mounted on the vehicle body, the number of parts to be assembled on the vehicle assembly line is increased, and the vehicle is mounted. It is not possible to sufficiently reduce the number of assembly steps. That is,
The work efficiency is lowered due to an increase in the work in the vehicle compartment where the workability is poor, and the work is complicated because the operator gets on and off the vehicle interior.

The present invention has been made in view of the above points, and an object thereof is to devise a procedure for attaching an air conditioner to a vehicle body to reduce the work of assembling parts in a vehicle assembly line. It is intended to reduce the number of man-hours for assembling the entire vehicle and to simplify the parts assembling work.

[0005]

In order to achieve the above object, in the means for solving the problems of the present invention, an air conditioner is attached to an instrument panel so as to be in a sub-assembled state, and then the instrument panel is attached to a vehicle body.

[0006] Specifically, the invention of claim 1 is directed to a method of mounting a vehicle air conditioner disposed inside an instrument panel in a vehicle compartment. Then, a mounting portion for the air conditioner is provided on the back side of the instrument panel, the air conditioning device is attached to the mounting portion for the instrument panel outside the vehicle compartment to be in a sub-assembly state, and then the instrument panel is moved into the vehicle compartment. And attach it to the car body.

According to the above-mentioned method, first, the air conditioner and the instrument panel can be easily integrated with each other on the subassembly line. Therefore, it is possible to reduce the work on the vehicle assembly line, reduce the number of assembly steps for the entire vehicle, and simplify the assembly work for the air conditioner.

According to a second aspect of the invention, in the first aspect of the invention, the air conditioner is divided into an air conditioning unit for generating conditioned air and a blower unit for blowing air for air conditioning to the air conditioning unit, The unit and blower unit shall be mounted separately on the instrument panel. That is, the air conditioner is divided into two units,
By attaching to the instrument panel one by one,
The weight of the unit supported by one operation can be reduced to facilitate the installation operation.

According to a third aspect of the present invention, in the second aspect of the present invention, the mounting portion of the instrument panel extends from one end portion in the vehicle width direction of the instrument panel to the other end portion of the instrument panel. Provided on an instrument panel member that supports the main body of the panel, and provided on both the air conditioning unit and the blower unit, engaging portions that engage with each other,
When the air conditioning unit is first attached to the instrument panel member and then the air blowing unit is attached, the engaging portion on the air blowing unit side is engaged with the engaging portion on the air conditioning unit side.

That is, first, the relatively large and heavy air conditioning unit is firmly fixed to the instrument panel member, and then the blower unit is fixed to the air conditioning unit and the instrument panel member. At this time, the air blower unit can be positioned accurately and easily by engaging the engaging portions provided on both units with the other.

According to a fourth aspect of the present invention, in the third aspect of the present invention, one of the engaging portions of the air conditioning unit and the blower unit is a projecting piece extending toward the other engaging portion, and The other engaging portion is a hole formed so that the protruding piece fits in, and the tip end side of the protruding piece is
A claw portion that is fitted into and locked in the hole is provided.

That is, when attaching the blower unit, a protruding piece extending from one of the air conditioning unit and the blower unit toward the other is fitted into the other hole portion, and the claw portion of the protruding piece engages with the hole portion. By stopping it, it is possible to prevent the protruding piece from coming off and temporarily fix the blower unit.
Further, for example, when the air blower unit is mounted on the instrument panel member with the instrument panel turned upside down, it is only necessary to slide the instrument panel member toward the air conditioning unit to temporarily move the air blower unit. Fixation can be done.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects of the present invention, the air conditioner includes a pipe member extending forward of the vehicle body through an installation hole formed in a dash panel of the vehicle. A guide portion that extends forward of the vehicle body and is inserted into the hole portion of the dash panel so as to guide the pipe member to the installation hole is provided.

That is, in general, when an instrument panel in a sub-assembled state by attaching an air conditioner is attached to a vehicle body in a vehicle assembly line, a pipe member from the air conditioner must be passed through a disposition hole of a dash panel. In the conventional automatic robot for mounting the instrument panel, such a precise operation cannot be performed, and when this robot is used, the pipe member may come into contact with the dash panel and be damaged.

On the other hand, according to the present invention, since the guide portion for guiding the pipe member to the predetermined position is provided in the air conditioner,
When the instrument panel is attached to the vehicle body, the pipe member can be accurately inserted into the installation hole even by using the robot as described above, and thus the pipe member can be reliably prevented from being damaged. . Therefore, even if the conventional production equipment is used as it is, the instrument panel can be mounted in a desired state.
