Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mounting structure for a vehicle air conditioner, and particularly relates to a mounting structure for a vehicle air conditioner suitable for an air conditioner installed on a roof. .

[Conventional technology]

Conventionally, the installation structure for an air conditioner mounted on the roof of a vehicle has been such that the bottom surface of the air conditioner is shaped to match the shape of the roof of the vehicle, and the air conditioner is installed with a seal packing interposed therebetween. In addition, related installation structures such as
No. 10178 is mentioned [Problems to be solved by the invention] The above-mentioned conventional technology does not give sufficient consideration to the modification of existing vehicles that do not have an air conditioning system to provide air conditioning. It was necessary to take measures against this, and there were problems in terms of airtightness and watertightness. That is, in existing vehicles that have been manufactured for many years, there are irregularities of about ±20 mm with respect to the standard roof surface due to undulating deformation or local deformation of the roof plate. When an air conditioner is mounted on the roof of such a vehicle, it is difficult to completely prevent leakage of air and water even if a sheet seal is interposed between the roof and the air conditioner. In other words, the amount of deflection of the seal packing is
Since it is about 15mm to 20mm, the unevenness of the roof surface is ±20mm.
If the gap is close to 1 mm, it is extremely difficult to eliminate the gap, even considering the followability of the seal packing, and there are problems with airtightness and watertightness.

In addition, when installing an air conditioner on the roof of an existing vehicle, the roof must be removed in order to provide a return opening for circulating air from inside the vehicle and a cold air discharge opening for cold air (or hot air) from the air conditioner. There was a problem in that the rigidity of the roof structure decreased and the deflection increased due to the installation of the air conditioner.

To deal with the above problem, it is possible to strengthen the roof or side walls when removing the roof, and at the same time remove the strain on the roof panels, but in that case, the preparation work of the car body for air conditioning modification is extensive. A new problem will arise in that the cost will increase. Furthermore, since gas cutting and welding are used during the above-mentioned vehicle body modification, there are also problems such as the need to replace interior materials at that time.

The purpose of the present invention is to provide air-conditioning modifications to vehicles.
To enable air conditioning equipment to be installed at low cost without using fire.

[Means for solving problems]

The present invention provides a vehicle air conditioner comprising a roof plate, a ceiling plate, a plurality of rafters arranged between the two and connected to both, and an air conditioner installed on the upper surface of the roof plate. An air vent and a conditioning air vent are provided on both sides of the rafter, penetrating both the roof plate and the ceiling plate, and a mounting bed with the air conditioner fixed to the upper surface is provided between the return air vent and the air conditioner. The mounting bed is fixed to the upper surface of the roof plate above the conditioned air vent, and the mounting bed is large enough to cover the return air vent and the conditioned air vent, and has a length that spans the plurality of rafters. an opening is provided at the upper part of the return air port and the conditioned air port, and the member having only the two openings has a flange facing outward on the lower surface of the outer periphery of the member. a flange is attached to the roof sheet by mechanical means, and a partition wall is provided between the return air port and the conditioned air port to partition between the lower surface of the mounting bed and the upper surface of the roof sheet, A packing is installed around the two openings between the upper surface of the mounting bed and the lower surface of the air conditioner.

[Effect]

The mounting bed on which the air conditioner is mounted is attached to the roof plate by mechanical means such as rivets, so it can be safely installed without welding or using fire, and the mounting bed manufactured at the factory can be used as is, making it inexpensive. It is something that can be done.

The mounting bed is large enough to cover the return air vent and conditioned air vent and is fixed to the roof board, and there is a gasket between the mounting bed and the air conditioner, so it is possible to reliably achieve watertightness and airtightness, and the air conditioner This allows maintenance and inspection of the air conditioner to be carried out by removing it from the mounting bed.

The roof structure of the vehicle before modification was not designed to be strong enough to carry an air conditioner, but the mounting bed is large enough to straddle multiple rafters and is fixed to the roof structure, so it strengthens the roof structure. This allows the air conditioner to be installed without the need for special reinforcing materials.

Since the partition means between the return air port and the conditioned air port between the roof plate and the ceiling plate uses a rafter that the vehicle has, it can be done at low cost.

[Example] An example of the present invention will be described below with reference to FIGS. 1 and 2. 1 is an air conditioner, and 2 is a compressor. , 4 is a fan for sucking outside air and cooling the condenser 3, 5 is a cooler, and 6 is for circulating air in the cabin and cooling it by the cooler 5, and then discharging it into the cabin again. I am a fan of 7 is a return port for taking in circulating air, 8 is a cooler 5
This is a drain receiver that exchanges heat with the air and collects water condensed from the air. 9 is a drain hole provided in the drain receiver 8, and 10 is a mounting bed for mounting the air conditioner 1. The upper surface of the mounting bed 10 is a flat partition wall corresponding to the bottom surface of the air conditioner 1, while the lower surface is formed to correspond to the upper surface of the roof. 11 is a roof structure forming a vehicle; 12
1 is a roof board, and 13 is a ceiling board. 14, 15, 1
6 are return openings opened in the roof plate 12, ceiling plate 13, and mounting bed 10, respectively; 17, 1;
8 and 19 are similarly opened conditioned air discharge openings. 20 is a rafter as a strength member provided between the roof board 12 and the ceiling board 13; 21 is a mounting bed 1;
0 is a bracket for mounting the air conditioner 1, 22 is a mounting leg provided on the air conditioner main body, and 23 is a vibration isolating rubber. 24 is a return filter for removing dust from the circulating air, and 25 is a duct for distributing conditioned air to the cabin.

is a partition wall for partitioning the inside of the mounting bed 10 into a circulating air flow path and a conditioned air flow path. 31 is a partition wall for partitioning the circulating air flow path and the duct 25.

Next, to explain the operation, the mounting bed 10 for mounting the air conditioner 1 is a bulkhead with a flat upper surface, and the lower surface is fixed to the roof board 12 across the plurality of rafters 20 of the roof structure 11. ,
It acts to reinforce the roof structure 11. Furthermore, by fixing the lower flange part of the mounting bed 10 to the roof board 12 by mechanical means such as rivets, there is no need to replace the interior material, and the installation can be performed even when the roof board 12 has irregularities or deformation. The air conditioner 1 can be mounted on a mounting bed 10 having a surface corresponding to the bottom surface thereof, and includes a return opening 16 and a cold air discharge opening 19 with sealing gaskets 26 and 27.
It acts to easily achieve airtightness and watertightness. Further, the partition walls 30 and 31 prevent the circulating air from the return opening 14 and the conditioned air from the fan 6 from mixing with each other at the lower part of the mounting bed 10, and perform a sealing function. Next, the packing guide 28
In addition to acting to prevent the butts 26 and 27 from shifting, they are also attached to the top surface of the mounting bed 10 by welding or the like to form a watertight structure, so that the drain discharge hole 9 can be connected to the top surface of the mounting bed 10. The condensed water discharged through the gaskets 26 and 27 passes through the return opening 16 and the conditioned air discharge opening 1.

Furthermore, by providing the bracket 21 at a position lower than the top surface of the cooler bed 10, the height of the air conditioner 1 protruding from the top surface of the vehicle roof can be minimized. Particularly in vehicles, vehicle limits are set to limit the dimensions that protrude above the roof, so it is important to make the air conditioner 1 thin and to mount it as low as possible on the roof. It is particularly effective to make the position lower than the top surface of the mounting bed 10.

According to such a configuration, by mounting the air conditioner 1 on the roof via the mounting bed 10, airtightness and watertightness can be easily ensured regardless of the unevenness or deformation of the roof board 12. In addition, the mounting bed 1
0 is attached across the plurality of rafters 20 forming the roof structure 11, so it acts effectively as reinforcement for the roof structure 11, and there is no need to provide a special reinforcing member. Furthermore, by attaching the bracket 21 below the top surface of the mounting bed 10, the height of the air conditioner 1 from the roof surface can be kept low.

Since the mounting bed 10 on which the air conditioner 1 is mounted is attached to the roof plate 12 by mechanical means such as rivets, it can be safely attached without welding, that is, without using fire, and the mounting bed manufactured at the factory can be used as is. , which can be done at low cost.

The mounting bed 10 has a size that covers the return air vent and the conditioned air vent and is fixed to the roof plate 12, and a gasket 2 is provided between the mounting bed 10 and the air conditioner 1.
