Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a battery case mounting device for a battery type vehicle, and particularly to one that prevents the battery case from popping out.

As a battery type vehicle, for example, a battery lift truck is known, and among these, a counterbalance type vehicle has a structure as shown in FIG.

The forklift 10 is equipped with a mast device 12 for performing fork work at the front of a vehicle body 11, and a counterweight 13 at the rear for maintaining balance with cargo. A battery case 14 is mounted on the middle upper surface of the battery case 11.

The vehicle body 11, as shown in FIGS. 1 and 2,
Left and right side plates 15, a floor plate 16 attached to the front upper part of the side plates 15, a bottom plate 17 attached to the lower part of the side plates 15, a rear plate 18 connecting the rearmost ends of the side plates 15, It is composed of at least a back plate 19 arranged in front of the plate 18 and provided between the left and right side plates 15.

Support pieces 20 and 21 for supporting the battery case 14 are provided at the middle and rear portions of the left and right side plates 15.
is provided. These support pieces 20 and 21 are arranged on the upper surface of the side plate 15, that is, at a position lower than the floor surface.

An instrument box 22 is mounted on the floor plate 16, and a counterweight 13 is fixed to the rear plate 18. The lower ends of the main columns of the head guard 23 are fixed to these.

The battery case 14 consists of a cubic case main body 24 that is open at the top, and a cover or bonnet 25 for closing the opening. A seat 27 is attached to the upper part of the bonnet 25 near the front.

A required number of batteries are housed in the case body 24, and the bonnet 25 can be opened and closed in order to check the fluid level and other aspects of the batteries. Furthermore, when replacing the battery, etc., the bonnet 25 having the seat 27 gets in the way, so it can be removed from the hinge mechanism 26.

The battery case 14 as described above is placed on the support pieces 20 and 21 of the vehicle body 11, and is held in place by its own weight and the weight of the battery.

Since the support pieces 20 and 21 are provided at a position slightly lower than the floor surface, they will not slip off from the vehicle body 11. That is, the battery case 14 is fitted and seated in the recess formed in the vehicle body 11 as described above.

By the way, the battery case 14 mentioned above is seated on the support pieces 20 and 21, but the battery case 14 is
There is a risk of it flying out from the vehicle body 11 if it shakes or vibrates or falls over, so in consideration of this, the support piece 21 of the vehicle body 11 and the battery case are not only kept in place. A bolt is screwed between the bottoms of the parts 14 to removably fix the parts.

The battery case 14 is removable.
This is because it is necessary to load and unload the vehicle from the vehicle body 11.

However, in the past, the bolt was located below the battery case 14 near the rear wheel, so although the structure was extremely simple and perfect, it was very difficult to tighten or unscrew the bolt. It was difficult to do.

This invention was devised in order to solve the problems mentioned above, and its main purpose is to fix the battery case to the car body near the floor surface of the car body so that the bolts can be fixed. To provide a battery case mounting device for a battery type vehicle that allows easy screwing and unscrewing operations and does not hinder loading and unloading work of the battery case.

Another object of the present invention is to cut out a part of the side plate constituting the vehicle body, and provide a cover that closes the cutout so that it can be rotated to open and close, and the cover has a horizontal piece and a vertical piece in an inverted approximately L shape.
On the other hand, the battery case is provided with a projecting piece located below the horizontal piece of the lid body when the lid is closed, and these horizontal pieces and the projecting piece are fastened with bolts,
To provide a battery case mounting device for a battery type vehicle, in which when the battery case is removed from the vehicle body, the bolt is unscrewed and the lid is opened, thereby avoiding confrontation with the projecting piece of the battery case. There is something to do.

Still another object of the present invention is to provide a battery case mounting device for a battery type vehicle, which is provided with the above-mentioned mechanism on only one of the left and right sides, and which prevents the battery case from flying out.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of embodiments of the present invention will be explained below based on the drawings.

The battery case mounting device 1 of the present invention is installed on a vehicle body 1.
1 , a lid 3 that can close the notch 2 by cutting out a side plate 15 , which is a part of the battery case 1 Its main parts are comprised of a protruding piece 5 that is partially protruding, and a bolt 6 that removably fastens the lid 3 and the protruding piece 5.

The side plate 15 has an inverted substantially L shape with a horizontal piece 15' and a vertical piece 15'', and the lid body 3 is also in an inverted shape with a horizontal piece 3' and a vertical piece 3'' so as to continue with this. It is roughly L-shaped.

The pivot 4 is horizontal in the front-rear direction, and in the case of this embodiment, the lower end of the vertical piece 3'' of the lid body 3 and the vertical piece 15'' of the side plate 15 are pivotally connected. The lid body 3 can be rotated from a closed position shown in FIG. 2 to an open position shown in FIG. 3.

The protruding piece 5 protruding from the battery case 14 is
When the lid body 3 is closed, the horizontal pieces 3' are located close to each other and face each other below.

A vertical through hole 7 is bored in the horizontal piece 3' of the lid body 3, and a threaded hole 8 is screwed into the protruding piece 5.

Then, when the bolt 6 inserted into the through hole 7 is screwed into the screw hole 8 of the projection piece 5, the lid body 3 and the battery case 1 are connected.
4 is fixed, and since the lid body 3 and the vehicle body 11 are pivotally connected in advance by the pivot 4, the battery case 14 is fixed to the vehicle body 11 after all.

In the embodiment shown in the drawings, the mounting device 1 is provided only on the left side, and one side is omitted.
It is also possible to provide the mounting devices 1 on both the left and right sides.

In the case where the mounting device 1 is disposed only on one side as in this embodiment, it is possible to simply use it alone, but it is desirable to take some measures.

That is, in FIG. 2, if the contact point between the horizontal piece 15' of the side plate 15 on the right side and the battery case 14 is A, the bottom right corner point of the battery case 14 is B, and the center of the pivot 4 is O. If the straight line AO is equal to or larger than the straight line BO, the battery case 14 will rotate together with the lid 3 in the upper left direction (counterclockwise in the figure).

To prevent this, the straight line AO must be less than the straight line BO. In other words, the position of the pivot 4 may be set so as to satisfy the above conditions.

In this way, the side wall surface of the battery case 14 from point A to point B will come into contact with the horizontal piece 15' of the side plate 15, and the above-mentioned rotation will be prevented, and the single mounting device 1 will be able to The same effect as when two mounting devices are attached can be obtained.

In this embodiment, the lid body 3 is formed into an inverted approximately L-shape consisting of a horizontal piece 3' and a vertical piece 3'' depending on the relationship with the projecting piece 5 of the battery case 14.
It is also possible to use only the horizontal piece 3' depending on the mounting position.

As mentioned above, according to the present invention, the bolts for fixing the battery case are located on the floor of the vehicle body, so unlike the conventional method where the bolts are located in a narrow space, it is extremely easy to tighten and unscrew them. And it can be done quickly.

Of course, this is even more noticeable when the mounting device is provided on only one side.

Since the structure is very simple, it can be implemented immediately, and its practical effects are tremendous.
