Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vehicle air conditioner installed in a construction vehicle, etc., and specifically relates to the structure of a box in which air conditioning equipment is housed.

(Prior art) Air conditioners installed in the driver's cab of vehicles such as construction vehicles must have a structure that allows installation in as small a space as possible, and must be installed so that the air outlet faces the driver's cab. The box body of an air conditioner is often located next to the driver's cab and in contact with the side panel of the vehicle, so it is impossible to inspect or take in and out the air conditioning equipment from the side; The box body consists of an upper lid, and the upper lid of the box body is removed so that the air conditioning equipment can be inspected and put in and taken out from above.

As shown in FIG. 5, in the conventional box body of this type of air conditioner, the top opening of the box body 1 is not open over the entire horizontal cross section of the body, but there are horizontal peripheral edges 1A, 1A around the opening. There were many mounting methods in which the top cover 2 was placed on the horizontal surrounding edges 1A, 1A and fixed with screws or the like.

In this case, the horizontal circumference edge 1A, 1A protrusion allowance
For A' and A', the inner width B of the box body 1 is, for example, 27 cm.
The length is about 3 cm, and by fixing the receiving members 3', 3' such as nuts to this, the receiving members 3', 3' are fixed.
3' was used to fix the upper cover 2 with screws.

(Problem to be solved by the invention) As the projecting allowances A' and A' are large, the width of the opening becomes B-2A' = ≈21 cm, and as a result, the air conditioning equipment to be incorporated into the box body 1 becomes Since the width of the box is limited to the size that can be taken in and out from this opening, it can only accommodate air conditioning equipment that is considerably smaller than the actual internal width B dimension of the box body 1.
There is a problem in that the space inside the box body 1 cannot be used effectively, and the disadvantage is that the air conditioner becomes larger or its capacity becomes smaller.

In order to address these problems, the present invention aims to make effective use of the space inside the box. By making the bracket removable, the bracket can be removed from the receiving member before inserting or removing air conditioning equipment from the top opening, thereby reducing the amount of protrusion by the amount of the bracket. By making effective use of the space inside the box body, the box book can be made more compact or its capacity can be increased.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention, as illustrated in the drawings, is a box structure of a vehicle air conditioner, which is used for air conditioning equipment such as a heat exchanger 9. A box main body 1 whose top is completely open for loading and unloading from above, and a top lid 2 that covers the top opening.
and a plurality of fixing means for fixing the top lid 2 to the box body 1, each of the fixing means includes a receiving member 3, a bracket 4, and a first screw member 6a.
and a second threaded member 6b, the receiving member 3 is formed of a small piece-like member having a horizontal threaded hole 5 that is screwed into the first threaded member 6a, and is attached to the inner surface of the side wall of the box body 1. The bracket 4 is fixed at multiple locations on the upper part of the second screw member 6b so that the center line of the horizontal screw hole 5 faces horizontally.
A horizontal plate piece 4a is formed from a horizontal plate piece 4a having a vertical screw hole 7 screwed into the horizontal plate piece 4a, and a vertical plate piece 4b bent at a right angle from the horizontal plate piece 4a and having a horizontal hole 8 corresponding to the horizontal screw hole 5. The box body 1 is placed so that the piece 4a is on top and the vertical plate piece 4b is on the bottom, and the horizontal plate piece 4a is based on the position of the vertical plate piece 4b.
By screwing the first screw member 6a and the horizontal screw hole 5 so as to be located on the inner center side, the first screw member 6a is removably fixed to the receiving member 3, and
A hole corresponding to the vertical screw hole 7 of the horizontal plate piece 4a of the bracket 4 is bored in the upper cover 2, and the second screw member 6b is screwed into the vertical screw hole 7, so that the bracket 4 is screwed into the hole. On the other hand, the upper cover 2 is removably fixed,
In addition, the protrusion amount A of the receiving member 3 from the inner surface of the side wall of the box body 1 toward the inner center side is
is fixed to the receiving member 3 by screwing the first screw member 6a and the horizontal screw hole 5, the tip of the first screw member 6a is set to be in a position close to the inner surface of the side wall. This is what I did.

(Function) By having the above-mentioned means, the present invention can remove the second screw member 6b and the first screw member 6a, respectively. Since the air conditioning equipment can be inserted and removed with only the member 3 fixed to the box body 1, the effective width dimension at the top opening is the internal width B dimension, which is twice the protrusion A of only the receiving member 3. The protrusion amount A of the receiving member 3 is the thickness of the nut alone or the thickness of the mounting plate (depending on 0.2 cm), which is 1.5 at most.
Since it is about cm, the effective width dimension is expanded by the amount by which the bracket 4 is removed.

Note that if the receiving member 3 is formed from a thick iron plate, it is possible to provide the horizontal screw hole 5 in the iron plate itself and omit the installation of a nut, and furthermore, the protrusion allowance A is reduced, making it possible to reduce the effective width dimension. is expanded.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

(Embodiment 1) Figures 1 to 3 show one embodiment of the present invention, in which 1 is a box body for storing air conditioning equipment such as a heat exchanger 9 and a heater 10. The top is open over the entire surface, making it easy to put in and take out from above. In addition, 11 is the case of the heat exchanger 9,
12 is a damper, and 13 is a fan.

Reference numeral 2 denotes an upper lid that covers the top opening of the box body 1, and the illustrated example has a structure with a descending edge around the periphery.

As a structure for fixing the upper lid 2 to the box body 1, the box body is provided with fixing means consisting of a receiving member 3, a bracket 4, a first screw member 6a, and a second screw member 6b.

The receiving member 3 is made by using a small piece-shaped two-stage bent plate as a substrate, drilling a hole in it, attaching a nut coaxially to the hole and welding it, and using the nut as the horizontal screw hole 5. It is formed into a bent plate with screw holes.

This receiving member 3 is placed at a plurality of locations apart from each other on the inner surface of the side wall of the box body 1, for example, at seven locations on the box body 1.
It is fixed by welding or the like so that the protrusion A from the inner surface of the side wall toward the center inward becomes small as described later, and the center line of the horizontal screw hole 5 faces in the horizontal direction.

Since the board of the receiving member 3 is a thin board, the horizontal screw hole 5 cannot be directly screwed in, so a nut is attached to the board.The reason why the board is a two-step bent board is that The upper edge of the side wall 1 is slightly bent inward in two steps to prevent the upper cover 2 from protruding, thereby forming a diaphragm structure.

On the other hand, the bracket 4 has a plate bent at right angles as a base plate, and a horizontal plate piece 4a that can come into contact with the back surface of the top cover 2 when the top cover 2 is covered with the top opening of the box body 1.
and a vertical plate piece 4b that can be in contact with the side surface of the receiving member 3.
It has

This bracket 4 is fitted with a second threaded member 6b such as a bolt or screw inserted into a hole (not shown) provided at a predetermined location of the upper lid 2 to correspond to a vertical threaded hole 7 to be described later. A horizontal hole 8 into which a first screw member 6a such as a bolt or screw to be screwed into the horizontal screw hole 5 of the receiving member 3 can be inserted is provided in the horizontal plate piece 4a. 4b, respectively.

Note that a nut is used as the vertical screw hole 7 in the same manner as the horizontal screw hole 5 of the receiving member 3, and is welded to the horizontal plate piece 4a.

This bracket 4 is connected to the receiving member 3.
is removably fixed as shown below.

That is, with the horizontal plate piece 4a of the bracket 4 facing upward,
The vertical plate piece 4b is facing down, and the horizontal plate piece 4a is the vertical plate piece 4.
The horizontal hole 8 is inserted into the receiving member 3 so as to be located on the inner center side of the box body 1 with reference to the position b.
When the first screw member 6a is inserted into the horizontal hole 8 and then screwed into the horizontal screw hole 5, both 4 and 3 are fixed.

Then, when the first screw member 6a is removed, the bracket 4 is removed from the receiving member 3.

Here, to explain the above-mentioned protrusion amount A of the receiving member 3 from the inner surface of the side wall of the box body 1 toward the inner center side, this protrusion amount A is defined as the protrusion amount A when the bracket 4 is connected to the first screw member 6a The first screw member 6a is set so that when it is fixed to the receiving member 3 by screwing into the screw hole 5, the tip of the first screw member 6a is close to the inner surface of the side wall, as shown in FIG. The receiving member 3 is formed using the two-stage bent plate and has a shape such that the nut constituting the horizontal screw hole 5 is located on the inner surface side of the side wall.

Next, the upper lid 2 is detachably fixed to the bracket 4 as described below.

That is, when the top opening of the box body 1 is covered with the top cover 2, the vertical screw hole 7 of the bracket 4 and the top cover 2
In this state, after inserting the second screw member 6b through the hole, insert the second screw member 6b into the vertical screw hole 7.
When screwed together, both 2 and 4 are fixed.

Then, if the second screw member 6b is removed, the upper cover 2
is removed from the bracket 4.

In the box formed as described above, the top cover 2 can be removed from the bracket 4 by removing the second screw member 6b, and the top cover 2 can be removed from the bracket 4 by removing the second screw member 6b.
By removing the bracket 4, the receiving member 3
It is structured so that it can be removed from the
There is no part that protrudes inward from the top opening of the box body 1 by the amount of the bracket 4, and the protrusion amount A becomes the second
As shown in the figure, only the receiving member 3 is required, the effective width dimension is expanded, and the space can be used effectively accordingly.

When the air conditioning equipment has been assembled into the box body 1, the bracket 4 is screwed into the receiving member 3 by the first threaded member 6a and the horizontal threaded hole 5 as described above.
After the upper lid 2 is fixed to each bracket 4, the upper lid 2 is fixed to each bracket 4 by covering the top opening and screwing the second screw member 6b into the vertical screw hole 7.

The fixing of the top cover 2 is thus completed, but if it is necessary to take out the stored air conditioning equipment, the top cover 2 and the bracket 4 can be removed in this order as described above.

(Embodiment 2) Next, FIG. 4 shows another embodiment of the present invention, in which the box body 1 has a top opening that is equal to the horizontal cross-sectional area of the box body 1 without constricting the edge of the top opening. In addition to forming an opening, the upper cover 2 is formed into a flat plate.

In this case, the receiving member 3 is directly fixed to the upper part of the inner surface of the side wall of the box body 1 using a nut.

The bracket 4 has the same structure as the example shown in FIGS. 2 and 3, and the bracket 4 is attached to the receiving member 3 in the same manner as in the first embodiment.
It is possible to connect and disconnect.

In this example, there is an overhang A corresponding to the thickness of the nut as the receiving member 3, but this is about 1 cm at most, and in this example as well, the effective width of the top opening is expanded by the amount that the bracket 4 is removed. Ru.

(Effects of the invention) According to the invention having the structure and action described above,
Since each bracket 4 is configured to be removable from a plurality of receiving members 3 fixed to the upper part of the inner surface of the side wall of the box body 1, the receiving members 3 are the only members that narrow the top opening. The projecting allowance A can be reduced by 4 times the amount of the bracket, and the space inside the box body 1 can be used effectively, so that the external dimensions of the box body can be reduced by this amount and compactness can be achieved. In other words, it is possible to incorporate a correspondingly larger air conditioning equipment, and therefore the capacity can be increased in the same space.
