Abstract

PURPOSE:To prevent deformation of plate even if shock is applied by accidental dropping of a battery by installing a shock absorber on the terminal side of a battery. CONSTITUTION:A plurality of columnar projections 12 are installed on the upper surface of an upper cover 11. When shock is applied in an X direction, columnar projections 12 are crushed and shock energy is absorbed to prevent an electrode plate from deforming. By installing a shock absorber at least in terminal direction, problems such as deformation of plates caused by short due to contact between plates having different polarities when a battery is dropped and plates are moved can be prevented.

Description

[Detailed description of the invention] (Technical field) This invention is a book about storage batteries.

(Background technology) Figure 1 shows an exploded perspective view of a conventional storage battery.
Figure 2 is a side view, Figure 2 is a front view, Figure 2 is an exploded perspective view, Figure 2 is a perspective view of the assembly, and Figure 3 shows the structure of the battery circular part.

In general, a storage battery has a plurality of electrode plates 1 as shown in Fig. 1.
．． 2 are faced to each other with a spacer 3 in between, and the same polar plates □ are connected by a connecting portion 14.5. Here, electrode plates 1 and 4
is a positive pole, and 2 and 5 are negative poles. Further, pole posts 6.7 are provided on the connecting members 4, 5 to protrude and penetrate to the outside of the battery case 8'. In this way, a plurality of battery blocks A as shown in FIG.
A storage battery as shown in FIG. 2 is housed inside the container. 17 indicates a terminal. Each battery block A has a battery case 8
The 5th side is inserted in the @viewing state,
There is a gap between the battery block and the inner lid to temporarily store the electrolyte, so that if an impact is applied in the direction of the arrow in Figure 3, the electrode plate will move. In the figure, IO indicates the inner lid, and 11 indicates the upper lid.

For example, if a storage battery is accidentally dropped in the X direction (reverse arrow direction) and a strong impact is applied to the electrode plate, the relatively soft lead-based electrode will move in the X direction relative to the battery case 8. This has the disadvantage of causing deformation as shown in FIG. 4, resulting in failures such as contact and short circuit between different poles.

(Purpose of the invention) The invention was proposed in view of the above points, and it is possible to provide a shock absorbing material on the surface where the terminal is provided, so that the electrode plate will deform even if it is subjected to an impact such as being accidentally dropped. The purpose of this is to provide a storage battery that does not cause any problems.

(@Akira Disclosure) Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 5 shows an embodiment of the present invention, and in the figure,
A plurality of cylindrical projections 12 are provided on the upper surface of the top lid 11, and when an impact is applied in the X direction, the cylindrical projections 12 collapse and deform, absorbing the energy of the impact and deforming the electrode plate. This was done so that there would be no

FIG. 6 shows another embodiment of the present invention, in which a thin lip 13 made of a material such as rubber is attached to the outer periphery of the upper surface of the upper lid 11.
When an impact is applied in the X direction as described above, the lip 13 is crushed and deformed to absorb the energy of the impact, thereby preventing deformation of the electrode plate and preventing failures such as short circuits.

FIG. 7 shows another embodiment of the present invention, in which a rubber or springy material 14 is sandwiched between the upper lid 11 and the inner lid 10 in the shape of a sandwich to absorb the impact applied in the X direction. .

FIG. 8 shows another embodiment of the invention, in which the upper lid 11 and the inner lid 10 are connected by a thin rib 15, and when an impact is applied in the X direction, this thin rib portion is crushed and deformed. It absorbs impact energy and prevents the electrode plates from deforming.

FIG. 9 shows an example in which shock-absorbing cylindrical protrusions are provided on the entire surface of a storage battery case.

(Effects of the Invention) As described above, the present invention provides a shock absorbing member at least in the direction of the terminals of a storage battery, so that when the storage battery is dropped, the electrode plate moves and a short circuit occurs due to contact between different electrodes. This has the effect of preventing failures that occur during
