Description

[Detailed Description of the Invention] This invention relates to a battery storage device for an electric vehicle.

Generally, electric vehicles have a large volume and are equipped with a large number of drive batteries.

Conventionally, the batteries are arranged in a storage case 2 placed on the vehicle floor 1 as shown in FIG. 6 to fix the battery 3..., the upper part of the case was closed with a removable lid 7, and the upper part of the lid 7 was used as a loading platform.

Batteries in electric vehicles are often replaced, so it is desirable to be able to easily attach and detach them. However, in the conventional fixing method described above, after removing the lid 7, multiple bolts 6 are further tightened. Loosen and pull out the batteries one by one, remove the seats 4, take out the battery 3... from the storage case, store the new battery in the storage case again, apply the seats 4, and remove the multiple bolts 6.・・・・・・
- must be tightened in sequence, and finally the lid 7 must be put on and the lid 7 must be fixed to the case 2, which requires a lot of effort to attach and remove, and has the disadvantage of a complicated structure and a large number of parts. .

This invention has been developed to improve and eliminate the above-mentioned drawbacks of the conventional art.The construction of this invention will be described below with reference to an embodiment shown in the drawings.

Fig. 2 is a longitudinal side view showing an embodiment of the present invention, in which 10 is the vehicle floor, 11 is the case, 12...
... indicates a battery, 13 a lid, 14 a presser rubber, 15 a sheet material, and 16 a stopper material provided above inside the case.

The case 11 is made of angle material and has a box-shaped frame shape, and a sheet material 15 made of asphalt or other appropriate material is laid on the bottom plate to prevent rust from leaking battery fluid and prevent movement of the battery. Each side is made of perforated metal with numerous ventilation holes for cooling the battery, and the entire case is fixed to the vehicle floor with bolts.

The presser rubber 14 has a band shape with a rectangular cross section having a narrow protruding strip 14a at the center of the lower surface, and the protruding strip 14a
It is fitted between the two batteries 12.12 to prevent horizontal movement of the batteries, and the lower surfaces of both sides of the protruding strip 14a are brought into contact with the shoulders of the adjacent batteries 12.12 on both sides.

The height dimension of the presser rubber 14 is made slightly higher than the top surface of the case 11 in its natural state with the lid 13 removed, so that it is compressed in the vertical direction when the lid 13 is fixed to the case 11, and its repulsion The force presses down on the shoulder of the battery and prevents it from moving up and down.

That is, the lid 13 is connected to the flange 11a on the upper surface of the case 11 with bolts or a one-touch clamp so that it can be easily attached and detached.

The stopper material 16 provided above the inner surface of the case 11 is for preventing horizontal movement of the battery 12 housed in the case 11 and protecting the case 11.

The length of the presser rubber 14 is equal to or slightly shorter than the width of the battery 12, or it is made of two small pieces.
~3 pieces may be used.

Furthermore, it may be used between each battery.

Further, the presser rubber 14 may be fixed to the back surface of the lid 13.

Note that the top surface of the lid 13 can be used as a loading platform.

As explained above, this idea stores multiple batteries in a case with a sheet material placed on the bottom to prevent rust and prevent battery movement, and the batteries are placed between the top surface between the batteries and the lid of the storage case. A presser rubber with a convex part that is inserted between the batteries and comes into contact with the shoulder is interposed, and when the lid of the storage case is closed, the battery is fixed in the case with the presser rubber, so just by removing the lid, the battery can be removed immediately. It is now possible to attach and detach the battery, making it easy to replace the battery.

In addition, since a sheet material is provided at the inner bottom of the case, it is possible to prevent corrosion of the case and the vehicle floor due to battery fluid leakage, and to prevent the battery from moving, a stopper or other hanging member is provided at the inner bottom of the case. There is no need to provide

Furthermore, by using a presser rubber, you can secure the battery by simply closing the lid on the case.
The structure for fixing the battery is simple, the number of parts is reduced, and it can be implemented at low cost.Furthermore, since there are no obstructive parts inside the case, it is easy to insert and remove the battery, and there is less damage to the battery. It is also easy to handle.

Furthermore, in the present invention, the presser rubber has the function of securing the battery to the floor by utilizing its elasticity, and the presser rubber has the function of securing the battery to the floor side by using the elasticity of the rubber. Because of this, it is possible to prevent the battery from moving in the lateral direction, and it is possible to fix the battery very firmly.
