Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a battery case, and more specifically to a swing structure of a battery case that is horizontally rotatably attached to a frame of an industrial vehicle such as a forklift truck. .

2. Description of the Related Art In general, in industrial vehicles such as forklift trucks, battery cases are mounted so that they can be swung horizontally in order to facilitate engine maintenance and other services under the engine hood. That is, it is normally fixed to the frame (during traveling operations), and is provided so that it can be moved horizontally from its mounting position during maintenance.

3 and 4 are drawings showing the specific swing structure, in which a fulcrum pin b is vertically raised from a frame a in the engine hood and protrudes from the side wall of a battery case c. A pin support d formed in the shape of a cylinder with a lid and opening downward is attached to the pin support d so as to extend in the vertical direction. A pin support c is fitted into the fulcrum pin b so that it can move forward and backward and rotate freely, and the fulcrum pin b
The battery case c is provided so that the battery case c can be swung in the horizontal direction using as a rotational fulcrum.

Problems that the invention attempts to solve However, in the case of the above swing structure,
Since the battery case c is provided to swing using the fulcrum pin b as its rotational fulcrum, the rotational fulcrum cannot be moved from its mounting position when the battery case c is fixed. As shown in Fig. 4, even when the battery case c is swung through a 90 degree angle, a part of the fulcrum pin b remains in the mounting position of the battery case c in its fixed state. The problem is that the engine hood gets hot, making it impossible to carry out repairs, inspections, etc. inside the engine hood smoothly.

This invention is an attempt to improve the above-mentioned problems, and the problem to be solved lies in making it possible to swing the battery case away from its fixed position. has. That is, the present invention is characterized in that the battery case is made to swing through a link having one or more pivot points, and the specific means and operation thereof are as follows. It is.

Means for solving the problem A link lever having at least one pivot point is pivotally attached to the side wall of the battery case so as to be horizontally rotatable, and a cylindrical pin support is attached to the tip of the link lever. to fix.

A fulcrum pin is provided vertically protruding on the frame in correspondence with the pin support, and the pin support is loosely fitted to the fulcrum pin so that it can move forward and backward and rotate freely.

Function: By horizontally rotating the link lever while widening its angle, the battery case can be moved to a position away from the fixed position.

Embodiments Specific embodiments of the present invention will be described below with reference to illustrative drawings.

1 is a battery case, and the battery case 1 is formed into a rectangular box shape with an opening at the top. A link rod 2 is connected to the side wall surface of the short side of the battery case 1 so as to extend in the horizontal direction. That is, a pair of upper and lower holders 3, 3 formed in a cylindrical shape are fixed to the side wall surface of the battery case 1 so as to face each other.
A link piece 5 is horizontally rotatably attached via a pin 4 and a cylindrical holder 5a.
A cylindrical holder 5b is provided at the tip of the link piece 5, and the holder 5b includes a pin 6 and cylindrical holders 7a, 7a.
A pair of upper and lower link pieces 7, 7 are also pivotally connected to each other so as to be horizontally rotatable. Further, a pin support 8 formed in the shape of a cylinder with a lid and having an opening on the lower side is fixed to the distal end portions of the link pieces 7, 7 so as to extend in the vertical direction. On the other hand, a fulcrum pin 10 is vertically provided on the frame 9 in correspondence with the pin support 8, and the pin support 8 is movable in the vertical direction and rotatable in the horizontal direction. It's like being played with.

Further, on the bottom wall surface of the battery case 1, there is a stopper 11 formed in the shape of a round bar with an appropriate length dimension.
is extended and fixed in the longitudinal direction of the battery case 1 (in a direction substantially perpendicular to the rotation locus of the battery case 1 with the pin support 8 as a fulcrum), while a stopper 11 corresponds to the stopper 11 on the frame 9 side. Then, the holder 12 of the same stopper 11 is attached. That is, the Holger 12 is connected to the locking groove 12.
A is bent into a corrugated plate shape, and is provided so that the stopper 11 can be engaged with the engagement groove 12A when the battery case 1 is rotated to the fixed position.

Next, its effect will be explained.

FIGS. 1 and 2 are drawings showing a state in which the battery case 1 is fixed to the frame 9. In this state, the battery case 1 is fixed to the bottom wall of the battery case 1. A stopper 11 formed in a rod shape is attached to the holder 1.
It is in the state where it is engaged with the engagement groove 12A formed in 2.

When the battery case 1, which is fixed to the frame 9 in this manner, is horizontally rotated to perform maintenance on the engine, etc., the operation is performed in the following manner.

Lift up battery case 1. By lifting battery case 1, fulcrum pin 1
At 0, the action of sliding the pin support 8 in the pulling direction (rising action) is obtained;
Place the stopper 11 into the engagement groove 12A of the holder 12.
A more effective effect can be obtained.

Rotate the battery case 1 horizontally. With the stopper 11 pulled out from the engagement groove 12A as described above, by rotating the battery case 1 in the horizontal direction, the link lever 2
horizontally rotates using the fulcrum pin 10 as a fulcrum; more specifically, both link pieces 5 and 7 constituting the link rod 2 gradually expand their angles using the fulcrum pin 10 and both pins 4 and 6 as fulcrums. This provides a rotating action. By rotating both link pieces 5 and 7 using the fulcrum pin 10 and both pins 4 and 6 as fulcrums in this manner, the battery case 1 can be rotated significantly. That is, the second
The battery case 1 is fixed at the fixed position as shown by the dashed line in the figure (represented by the solid line).
It can be rotated to a farther position.

In the above embodiment, the stopper 11 is formed in the shape of a round bar, but the shape of the stopper is not limited to the shape of a round bar, and may be formed in a spherical shape. Further, the number of pivot points of the link 2 is not limited to the above embodiment, and can be increased or decreased as desired.

Furthermore, in the above embodiment, the pin support 8 was formed into a closed cylindrical shape with an opening on the lower side, but the pin support 8 was formed with openings on both sides, and the fulcrum pin 10 was provided with a flange. Alternatively, the lower edge of the pin support 8 may be supported by the support stand 10a of the support pin 10 or the frame 9.

Effects of the invention The invention is constructed as described above.
With the above configuration, it is possible to horizontally rotate the battery case to a position away from its fixed position, thereby making it possible to smoothly perform maintenance work on the engine, etc.
