Abstract

PROBLEM TO BE SOLVED: To lighten a controller box by using the same plate material without requiring to increase plate thickness by arranging an upper surface of a lifting sling so that it makes contact with a lower surface of a ceiling board. SOLUTION: A controller box 1 is constituted of a ceiling board 2, a bottom plate 3, side plates 4A, 4B arranged in the vertical direction by both end parts of the ceiling board 2 and the bottom plate 3 and side plates 5A, 5B in the longitudinal direction connected to the ceiling board 2 and the side plates 4A, 4B. Additionally, a cover 6 for inspection is installed on a square shaped opening part through a hinge 12 installed on the side plates 5A, 5B in the longitudinal direction. A lifting sling 7 is positioned so that an upper surface makes contact with a lower surface of the ceiling board 2 and it is welded on the lower surface of the ceiling board 2. Mass of the controller box 1 and instruments built in it is supported by whole of the surface making contact with the upper surface of the lifting sling 7 and the lower surface of the ceiling board 2, and a load is not locally concentrated on the ceiling board 2. Consequently, it is needless to increase thickness of the ceiling board or the side plates, etc., for improvement of strength, and it is possible to lighten the controller box.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control box for a vehicle.

[0002]

2. Description of the Related Art A conventional suspension structure for mounting a control box for a vehicle under the floor of a vehicle body includes a structure in which a hanging bracket is fixed to an upper surface of a ceiling plate of the control box (for example, Japanese Utility Model Application Laid-Open No. 62-76068), 2. Description of the Related Art There is known a structure in which a hanging bracket is provided at an upper end portion of a side plate of a cabinet (for example, Japanese Utility Model Laid-Open No. 3-7062).

[0003]

However, in the former structure, since the hanging bracket is welded only to a part of the upper surface of the controller box ceiling plate, the mass of the entire controller box (including the box and built-in equipment) is reduced. Will be concentrated around the hanging bracket mounting part,
Therefore, in order to secure the strength of the ceiling portion, it is necessary to increase the thickness of the ceiling plate. In the latter suspension structure, it is necessary to increase the thickness of the side plate integrated with the suspension fitting in order to improve the strength and rigidity of the suspension fitting. As a result, in both cases, it is necessary to increase the plate thickness, which in turn causes an increase in the mass of the entire controller box. There is a problem of getting high.

An object of the present invention is to provide a vehicle controller box which can be reduced in weight by using the same plate material without having to increase the plate thickness.

[0005]

Means for Solving the Problems An inspection cover having a ceiling plate and a bottom plate, both of which are formed in a mouth shape by side plates and covering the mouth-like opening, and a hanging metal fitting for supporting them on the vehicle body are provided. In the controller box for a vehicle, the upper surface of the hanging bracket is arranged so as to be in contact with the lower surface of the ceiling plate.

[0006] With this configuration, the mass of the controller box and the built-in equipment added to the hanging bracket from the ceiling board can be received over the entire surface of the hanging bracket in contact with the ceiling board.
The load is not locally applied to the ceiling portion, and the ceiling plate can be made the same thin plate as the side plate and the bottom plate.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The controller box 1 comprises a ceiling plate 2, a bottom plate 3 arranged in parallel with the ceiling plate 2, side plates 4A and 4B arranged in the vertical direction for connecting both ends of the two in the width direction, and the ceiling plate 2 and the side plate. It is constituted by longitudinal side plates 5A, 5B connected to 4A, 4B. An inspection cover 6 is attached to the opening formed in a mouth shape of the control box 1 via a hinge 12 attached to the longitudinal side plates 5A and 5B. As shown in FIG. 2, the hanging fitting 7 is located such that the upper surface thereof is in contact with the lower surface of the ceiling plate 2. When this hanging metal fitting 7 is positioned below the ceiling plate 2, as shown in FIG. 3, it is inserted into through holes 9 provided in advance in the longitudinal side plates 5A and 5B of the control box 1 and fixed after positioning. . Hanging bracket 7
The control box 1 is outfitted by mounting the exposed portion of the vehicle below the floor of the vehicle body 8.

When the controller box of the present invention is adopted, the weight of the controller box 1 and the devices incorporated therein is received by the entire surface in contact with the upper surface of the hanging metal fitting 7 and the lower surface of the ceiling surface 2. The load does not concentrate locally on 2. Further, the strength and rigidity of the ceiling portion are improved by welding the hanging metal member 7 having a U-shaped cross section to the lower surface of the ceiling plate 2. As a result, it is not necessary to partially increase the thickness of the ceiling plate or the side plate for improving the strength as in the case of using the structure of the conventional product, and the ceiling plate 2 is the same as the side plates 4A, 4B and the bottom plate 3. It is possible to unify with a thin plate. Unifying all plate thicknesses in this way makes it easier to remove materials, shortens setup time, facilitates inventory management of materials, and facilitates design, resulting in cost reduction. . Further, by unifying the controller box 1 with a thin plate, there is an advantage that the mass of the controller box 1 can be reduced. Further, as shown in FIG. 3, the hanging metal fitting 7 is inserted through through holes 9 previously formed in the control box longitudinal side plates 5A and 5B, thereby positioning the front, rear, left and right when the hanging metal fitting 7 is welded to the control box 1. Can be performed very easily as compared with conventional products.

Next, another embodiment will be described with reference to FIG.
When the longitudinal partition plate 10 is provided in the controller box 1, the hanging metal members 11A, 11B divided into right and left are welded after being inserted from the direction of the longitudinal side plates 5A, 5B, respectively. Similar effects can be obtained. In this case, the end of the hanging fitting 11 in the controller box is as long as possible in the longitudinal partition plate 1.
A value closer to 0 is desirable in terms of strength.

The cross-sectional shape of the suspension fitting 7 described in the embodiment is U-shaped in order to increase the strength, but may be L-shaped or square-shaped similarly.

[0012]

According to the present invention, it is possible to obtain a vehicle control box which can be reduced in weight by using the same plate material without having to increase the plate thickness.
