[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mechanism for holding a battery mounted on an industrial vehicle, and more particularly to a mechanism for preventing the battery from falling off.
[0002]
[Prior art]
As one form of industrial vehicle such as a forklift, a type using electricity as an energy source is known. Since the industrial vehicle of this form is usually equipped with a battery for storing electric power, it is often called a battery vehicle. Since battery cars do not emit exhaust gas, they are suitable for indoor work, for example, and demand is increasing.
[0003]
FIG. 4 is a diagram schematically showing a configuration of a forklift taken as an example of an industrial vehicle and a battery mounted thereon. This forklift has a configuration in which a battery is mounted under a seat. That is, the battery compartment 2 is provided under the seat 1, and the battery 3 is installed therein.
[0004]
The battery compartment 2 is provided with a battery holding mechanism 4 for preventing the battery 3 from jumping out from the battery compartment 2. The battery holding mechanism 4 is provided in preparation for an unexpected situation (for example, a fall of a forklift).
[0005]
FIG. 5 is a view showing a conventional battery holding mechanism, and shows a shape of the battery holding mechanism 4 when viewed from the direction of arrow A in FIG.
[0006]
The battery holding mechanism 4 is attached to a slit 11 formed at the upper end of the side wall of the battery compartment 2, a pin insertion portion 12 formed at the tip of the slit 11, and a position adjacent to the slit 11 on the side wall of the battery compartment 2. And the stopper pin 20 inserted into the pin insertion portion 12. The pin insertion portion 12 is formed by cutting a part of the side wall of the battery compartment 2 into a circular shape, and the diameter thereof is larger than the notch width of the slit 11. The clip 13 is attached to the outside of the battery compartment 2, that is, the side where the battery 3 is not installed. On the other hand, the stopper pin 20 includes a cylindrical main body portion 21 having a diameter substantially the same as the inner diameter of the pin insertion portion 12 and a handle 22 attached to the bottom surface of the main body portion 21.
[0007]
The stopper pin 20 is inserted into the pin insertion portion 12 from the outside of the battery compartment 2. Then, the stopper pin 20 is fixed to the battery compartment 2 by inserting the handle 22 into the clip 13 with the main body portion 21 of the stopper pin 20 inserted into the pin insertion portion 12.
[0008]
When the stopper pin 20 is fixed in this manner, the main body portion 21 of the stopper pin 20 protrudes inside the battery compartment 2 as shown in FIG. The protruding main body 21 holds the battery 3 inside the battery compartment 2. That is, the battery 3 is prevented from jumping out of the battery compartment 2.
[0009]
[Problems to be solved by the invention]
By the way, the battery 3 is often taken out from the battery compartment 2 for repair or maintenance. In this case, as a matter of course, the stopper pin 20 must be removed.
[0010]
At this time, if the stopper pin 21 is dropped between the battery compartment 2 and the frame 5, it is difficult to pick it up. This is because various electrical parts for controlling the forklift, hydraulic parts, and the like are arranged at this place, and it is difficult to put a hand.
[0011]
The subject of this invention is providing the battery holding mechanism which can improve the working efficiency at the time of removal | desorption of the battery mounted in an industrial vehicle.
[0012]
[Means for Solving the Problems]
The battery holding mechanism of the present invention holds a battery mounted on an industrial vehicle, and includes a slit at the upper end portion of the side wall and a circular pin insertion portion at the tip position of the slit, and accommodates the battery. A battery compartment, a cylindrical main body having a diameter equal to or slightly smaller than the inner diameter of the pin insertion portion, a handle provided on the bottom surface of the main body portion, and an upper surface of the main body portion And a stopper pin into which the main body portion is inserted into the pin insertion portion from the inside of the battery compartment.
[0013]
In the above configuration, when the stopper pin is fixed to the compartment, the main body portion is inserted into the pin insertion portion so that the handle passes through the slit. The stopper pin is inserted into the pin insertion portion from the inside into the battery compartment. At this time, since the retaining means is provided on the upper surface of the main body, the main body does not come out of the battery compartment.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0015]
FIG. 1 is a configuration diagram of the battery holding mechanism of the present embodiment. The position where the battery holding mechanism is provided is the same as that of the conventional configuration shown in FIG. 4 and is the upper end of the side wall of the battery compartment 2. Further, the configuration of the battery compartment 2, that is, the slit 11 formed at the upper end of the battery compartment 2 and the pin insertion portion 12 formed at the tip position of the slit 11 are the same as the conventional one shown in FIG. It is.
[0016]
The battery holding mechanism of this embodiment is characterized by a stopper pin. That is, the stopper pin 30 of the present embodiment is attached to the cylindrical main body 31 having the same diameter as the pin insertion portion 12 or slightly smaller than the inner diameter of the pin insertion portion 12, and the bottom surface of the main body portion 31. A handle 32 and a retaining rod 33 attached to the upper surface of the main body 31 are provided. The main body 31 and the handle 32 may be the same as the main body 21 and the handle 22 of the conventional stopper pin shown in FIG.
[0017]
FIG. 2 is a view of the stopper pin 30 as viewed from three directions. The stopper pin 30 is configured by welding a handle 32 to the bottom surface of the main body 31 and a retaining bar 33 to the upper surface of the main body 31. The material of the main body 31, the handle 32, and the retaining rod 33 is, for example, iron.
[0018]
The main body 31 has a cylindrical shape, and the height (or length) from the top surface to the bottom surface thereof is sufficiently higher (or longer) than the thickness of the side wall of the battery compartment 2.
[0019]
The retaining rod 33 is formed so that its tip protrudes from the main body 31 when attached to the main body 31. In the configuration shown in FIG. 2, both ends of the retaining rod 33 protrude outward from the circular surface of the main body 31.
[0020]
The retaining rod 33 may be attached on the center line of the circular surface of the main body 31, or may be attached at a position shifted from the center line as shown in FIG. When the retaining rod 33 is attached on the center line of the circular surface of the main body 31, the length of the retaining rod 33 needs to be longer than the diameter of the main body 31. On the other hand, when the retaining rod 33 is attached at a position deviated from the center line, the length of the retaining rod 33 is not necessarily longer than the diameter of the main body 31.
[0021]
Returning to FIG. 1, the procedure for attaching the stopper pin 30 to the battery compartment 2 will be described. The stopper pin 30 is fitted into the battery compartment 2 such that the main body portion 31 is inserted into the pin insertion portion 12 from the inside of the battery compartment 2. At this time, the handle 32 passes through the slit 11. In this operation, even if the stopper pin 30 is pulled strongly in the direction in which the frame 5 is provided, or even if the stopper pin 30 is pushed in in the direction in which the frame 5 is provided, Is provided with a retaining rod 33, which cannot pass through the pin insertion portion 12. That is, the stopper pin 30 does not penetrate to the side where the frame 5 is provided. Thereafter, the handle 32 is rotated in the direction of the clip 13 in a state where the main body portion 31 is fitted into the pin insertion portion 12. As a result, the handle 32 is held by the clip 13.
When the stopper pin 30 is fixed to the battery compartment 2 as described above, the main body 31 protrudes inside the battery compartment 2 because the main body 31 is sufficiently longer than the thickness of the side wall of the battery compartment 2. . The protruding portion holds the battery 3 in the battery compartment 2.
[0022]
As described above, when the stopper pin 30 is fixed to the battery compartment 2, the battery holding mechanism of the present embodiment is always inserted from the inside of the battery compartment 2, and the retaining rod 33 is provided. The stopper pin 30 does not penetrate to the side where the frame 5 is provided. Therefore, even if the hand is slipped inadvertently, the stopper pin 30 does not fall between the battery compartment 2 and the frame 5.
[0023]
When taking out the battery 3 from the battery compartment 2, it is necessary to remove the stopper pin 30 from the battery compartment 2. This procedure is the reverse of the procedure for fixing the stopper pin 30 to the battery compartment 2. That is, the handle 32 is removed from the clip 13, and the entire stopper pin 30 is pushed out to the side where the battery 3 is provided so that the handle 32 passes through the slit 11.
[0024]
As described above, when removing the stopper pin 30 from the battery compartment 2, since the retaining bar 33 is provided on the upper surface of the main body 31, the stopper pin 30 must be pushed out to the inside of the battery compartment 2. . Therefore, even in this case, the stopper pin 30 does not fall between the battery compartment 2 and the frame 5.
[0025]
In the above embodiment, in order to prevent the stopper pin 30 from falling between the battery compartment 2 and the frame 5, the retaining bar 33 is provided on the upper surface of the main body 31. However, an equivalent function is realized. There are various modifications. 3A to 3D show a modification of the stopper pin.
[0026]
The stopper pin shown in FIG. 3A is provided with a disc-shaped retaining member 41 on the upper surface of the main body. The stopper pin shown in FIG. 3B is provided with a square bar-shaped retaining rod 42 instead of the retaining rod 33 shown in FIG. 1 or FIG. The stopper pin shown in FIG. 3 (c) is obtained by integrally molding a cylindrical main body and a disc-shaped retaining member 41 shown in FIG. 3 (a). The stopper pin shown in FIG. 3D is obtained by integrally molding the main body portion and the protruding portion 43.
[0027]
【The invention's effect】
Since the stopper pin for holding the battery is provided with a retaining member, when the stopper pin is attached to the battery compartment or removed from the battery compartment, the stopper pin can only be removed from the inside of the battery compartment. . As a result, the stopper pin does not fall between the battery compartment and the frame of the vehicle on which the battery compartment is mounted.
[0028]
As a place where the stopper pin may fall due to carelessness, etc., the inside of the battery compartment can be considered, but at that time, the stopper pin will fall on the battery installed in the battery compartment. It is easy to pick up.
[0029]
Since it has a very simple structure, it is easy to manufacture and can be realized at low cost. Furthermore, the existing battery compartment can be used without any modification.
