DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery stopper device provided in an industrial vehicle such as a forklift for restricting lateral movement of a battery case mounted on a vehicle body.

[0002]

2. Description of the Related Art FIG. 10 shows a conventional battery stopper device. In addition, the arrow Up in the figure indicates the upper side of the vehicle, and the arrow L
H indicates the right side of the vehicle. As shown in the figure, in the case of a conventional general battery type forklift, a battery case 101 containing a large number of batteries is mounted on a roller in a battery storage chamber set at a substantially central portion of a frame 102, and maintenance is performed. Sometimes, it is configured to be able to be pulled out or pushed into the vehicle in the lateral direction as shown by an arrow in the drawing from an entrance provided on the right or left side of the battery storage room. The battery case 101 mounted in the battery storage chamber includes a rotary stopper 104 provided on the entrance side and an adjustable stopper 105 provided on the opposite side (rear side) of the entrance side. Lateral movement is regulated by The rotary stopper 104 is rotatably attached to a battery holder (not shown), and is always held at a position where the entrance is closed. When the battery case 101 enters and exits, it is pivoted upward in the direction shown by the arrow to open the entrance. Has become.

On the other hand, the adjustable stopper 105 is provided in order to cope with the fact that the width of the battery case 101 is not always constant and there is some variation depending on the manufacturer. In other words, the adjustable stopper 105 for absorbing variation is formed by stacking a plurality of stopper plates 106 formed of a plurality of thin plates having a substantially L-shape.
07, the battery case 101 is mounted on the stopper holder 108 by adjusting the number of used stopper plates 106.
Absorbs variations in width.

[0004]

However, some users who use the battery-powered forklift as described above use a battery case of a different size (a different battery capacity) besides the standard battery case. There is a demand that there is a case that you want to use. However, although the conventional battery stopper device described above has the adjustable stopper 105, the adjustable stopper 105 is only for absorbing the variation in the size of the battery case 101, and the adjustable stopper interval That is, since the adjustment width of the interval between the rotary stopper 104 and the adjustable stopper 105 is limited to a small range, the above request could not be met. In order to meet the above demand, for example, it is conceivable to widen the adjustment width of the stopper interval by, for example, greatly increasing the number of stopper plates 106 constituting the adjustable stopper 105. However, in such a countermeasure, the position of the center of gravity (center position) of the battery case 101 moves to the entrance side, resulting in a large displacement from the vehicle center line, which may impair vehicle stability.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to mount and hold battery cases of different sizes in a stable posture without impairing vehicle stability. It is to provide a battery stopper device that can perform the above.

[0006]

In order to achieve the above object, a battery stopper device according to the present invention has a configuration as described in each of the claims. Therefore, according to the first aspect of the present invention, the interval between the stoppers is defined by the interval between the main stoppers in a state where the sub-stopper is removed from the main stopper and the interval with the sub-stopper in a state where the sub-stopper is attached to the main stopper. And at least two types of adjustments are possible. That is, since the distance is adjusted by both the first stopper and the second stopper, the battery case can be mounted in a state where the position of the center of gravity of the battery case is small with respect to the center line of the vehicle. It does not impair vehicle stability. As a result, it is possible to set a large adjustment width of the stopper interval, and it is possible to mount even battery cases having greatly different sizes.

According to the invention of claim 2, according to claim 1,
In addition to the same effects as the invention, the main case of the first stopper provided on the entrance side of the battery storage room is displaced to the open position, and the battery case in the battery storage room is opened sideways with the entrance opened. It can be pulled or pushed in the direction. Furthermore, according to the third aspect of the invention, in addition to having the same operational effects as the second aspect, the number of plates constituting the main stopper of the second stopper is increased or decreased, thereby mounting the battery case. Fine adjustment for absorbing variations in the width of the battery case is possible, and lateral movement of the battery case can be reliably restricted.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic side view of a battery type forklift to which the battery stopper device according to the present embodiment is applied. As shown in the figure, a battery case 1 in which a large number of batteries are accommodated is mounted in a battery storage room 3 which is set substantially at the center of a frame 2 in the vehicle longitudinal direction.

FIG. 2 is a plan view showing a battery storage chamber and a battery stopper device, and FIG.
It is a line sectional view. The arrow Fr in the figure indicates the front of the vehicle, the arrow Up indicates the upper side of the vehicle, and the arrow LH indicates the right side of the vehicle. The front and rear sides of the battery compartment 3 are shorter than the battery case 1 on the front panel 3a.
It is formed in a rectangular shape slightly longer in the vehicle width direction defined by the rear panel 3b and the side panel 3c, and an entrance 4 is provided on a right side surface, which is one side surface. That is, the battery case 1 is configured so that it can be pulled out or pushed in the lateral direction of the vehicle from the entrance 4 of the battery storage room 3 as shown by an arrow in maintenance, and the battery case 1 is placed on the floor surface in order to smoothly carry out the operation. Is provided with a roller (not shown).

Next, a description will be given of a battery stopper device which restricts the lateral movement of the battery case 1 by contacting the left and right side surfaces of the battery case 1 mounted in the battery storage chamber 3 and holds the battery case 1 in a stable state. The battery stopper device is a first stopper provided on the entrance 4 side of the battery storage chamber 3 as a rotary stopper 11 as shown in FIGS. 4 and 5, and is provided on the opposite side (rear side) of the entrance 4 (FIG. 6).
And a fixed stopper 21 as a second stopper as shown in FIG.

As shown in FIGS. 4 and 5, the rotary stopper 11 is a main stopper mounted on a stopper holder 12 fixed to the front panel 3a via a support pin 11a so as to be vertically rotatable. It is constituted by a stopper arm 13 and a stopper plate 14 made of a rectangular thick plate as a sub-stopper detachable from the stopper arm 13. The stopper arm 13 extends substantially horizontally across the doorway 4 and can be rotated and displaced in a range of approximately 90 degrees between a closed position where the doorway 4 is closed and an open position where the stopper arm 13 is turned upward to open the doorway 4. ing. Note that the rotation end of the stopper arm 13 is such that the lock plate 16 provided at the base of the stopper arm 13 is connected to the side surface 12 a of the stopper holder 12 and the stopper holder 12.
Is regulated by abutting against a stopper bolt 17 provided at the first position.

The stopper holder 12 is provided with a lock pin 15 urged downward by a spring (not shown), and the stopper arm 13 is turned to the closed position to lock the lock plate 16. Lock hole 16
The stopper arm 13 is inserted from above to prevent an unexpected opening operation of the stopper arm 13. Therefore, the stopper arm 13
Is rotated in a state where the lock pin 15 is pulled out from the lock hole 16a against the spring and the lock by the lock pin 15 is released. The stopper plate 14 is detachably attached to the inner surface of the stopper arm 13 by attaching bolts 18.

On the other hand, as shown in FIG. 6 and FIG.
c or stopper holder 2 fixed to floor panel 3d
2, two sets of front and rear L-shaped plates 23 made of a plurality of thin plates (in the figure, a set of five sheets) as a main stopper, and a rectangular thick plate 1 as a sub-stopper
And a plurality of stopper plates 24.
The stopper holder 22 has a plurality of screw holes 22a whose axial direction is the vertical direction for mounting the L-shaped plate 23 or the stopper plate 24. Stopper plate 2
4 has a mounting through hole 24a at one end and a screw hole 24b to which an L-shaped plate 23 can be mounted at the other end, and the L-shaped plate 23 has a mounting through hole 23a at one end. ing. That is, the stopper plate 24
The L-shaped plate 23 is detachably attached to the stopper holder 22 or the stopper plate 24 by the attachment bolt 25.

According to the battery stopper device according to the present embodiment configured as described above, the stopper interval, which is the mutual interval between the rotary stopper 11 and the fixed stopper 21 installed opposite to each other, is basically the same. By adjusting the form of the stopper plates 14 and 24 as sub-stoppers, two intervals can be adjusted. That is, FIG. 8A shows a case in which the stopper plates 14 and 24 are not used. On the rotary stopper 11 side, the stopper plate 14 is detached from the stopper arm 13, and FIG.
On the fixed stopper 21 side, the stopper holder 22
, Only the L-shaped plate 23 is attached. Therefore, the stopper interval L1 at this time is determined by the stopper arm 13 as the main stopper and the L-shaped plate 23.

On the other hand, FIG.
4 and 24 are used, and the rotary stopper 1
A stopper plate 14 is attached to one stopper arm 13, a stopper plate 24 is attached to a stopper holder 22 of the fixed stopper 21, and an L-shaped plate 23 is attached to a tip of the stopper plate 24. Therefore, in this case, the stopper interval L2
Is narrower than when the stopper plates 14 and 24 are not used.

As described above, according to the present embodiment, the interval between the stoppers can be adjusted depending on whether or not the stopper plates 14 and 24 are used as sub-stoppers. In this case, the stopper is fixed to the rotary stopper 11. Since the stopper adjustment is performed on both sides by the expression stopper 21,
When the battery case 1 is mounted in the battery storage room 3, the displacement amount (deviation amount) between the center of gravity G (center position) of the battery case 1 and the vehicle center line CL can be suppressed to a small range, and vehicle stability can be reduced. It does not harm the degree (see FIGS. 2, 3 and 8). For this reason, the adjustment width of the stopper interval can be set large, and at least two types of large and small battery cases 1 having different sizes can be mounted. Here, the difference in the size of the battery case 1 means that not only the horizontal width but also the vertical width, that is, the length in the front-rear direction, is different. For example, regarding the front panel 3a or the rear panel 3b or the floor panel 3d. The position of the stopper device provided for regulating the position of the battery case 1 in the front-rear direction can be adjusted.

The size of the battery case 1 varies slightly depending on the manufacturer, but the variation in the width of the battery case 1 is limited to five in the fixed stopper 21 as shown in FIGS. 9A and 9B. Out of the set of L-shaped plates 23, unnecessary L-shaped plates 23a are rotated toward the front side or the rear side of the stopper holder 22 to adjust the number of sheets used as stoppers, and finely adjust the stopper intervals L1 and L2. Can be absorbed by In this case, since it is not necessary to remove the L-shaped plate 23, the adjustment operation can be performed easily, and the L-shaped plate 2
3 can be prevented from being lost. Further, in the present embodiment, the L-shaped plate 23 of the fixed stopper 21 is provided in two front and rear sets, so that the front and rear positions on the side of the battery case 1 can be supported. Can maintain a stable posture.

In the present embodiment, as the stopper plates 14 and 24, those having different lengths projecting inward from the inner surface are prepared in advance, and the stopper plates 14 and 24 are appropriately replaced and used. It is also possible to adjust the interval in two or more ways. Further, in the present embodiment, the case where the battery case 1 is inserted and removed from the side of the vehicle is described. However, the present invention can be applied to a vehicle of a type where the battery case 1 is inserted and removed from the vertical direction. 11 is changed to a fixed type. Further, as long as the vehicle is driven by a battery, the present invention may be applied to a vehicle other than a forklift.

[0019]

As described above, according to the battery stopper device of the present invention, the stability of the vehicle is not impaired.
Even in the case of battery cases having greatly different sizes, it is possible to mount and hold the battery case in a stable posture.
