Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a battery storage device for a hybrid electric vehicle.

[0002]

2. Description of the Related Art Conventionally, there is a hybrid electric vehicle in which an engine and an electric motor are combined to improve exhaust emission.

[0003] Such a hybrid electric vehicle includes a generator driven by an engine, and a battery for storing the generated power, and travels by using these as a power source to drive an electric motor.

[0004]

In such a hybrid electric vehicle, since a large number of batteries are mounted, for example, a large number of batteries are mounted on a pallet and stored in a battery chamber. (Japanese Unexamined Patent Publication No. 7-172
No. 190, etc.).

However, in this case, the pallet moves due to vibration or the like while the vehicle is running, which may result in damage to the harness or loosening of the terminal, which may cause a decrease in the function of the battery. For this reason, it is necessary to fix the pallet after storing it in the battery chamber, but it is difficult to easily perform the fixing work or the like due to restrictions on the size of the battery chamber and the storage direction.

Japanese Patent Laid-Open No. 5-159755 discloses a pallet in which a battery can be easily fixed and stored.

An object of the present invention is to solve such a problem.

[0008]

According to a first aspect of the present invention, there is provided a hybrid electric vehicle in which a large number of batteries are mounted on a pallet and housed in a battery compartment.

According to a second aspect of the present invention, there is provided a hybrid electric vehicle in which a large number of batteries are mounted on a pallet and housed in a battery compartment, wherein a bottom surface of the battery compartment receives a frame bracket provided on a lower surface of the pallet and the frame bracket. A guide rail that guides the pallet in the storage direction through the storage bracket.
A locking mechanism that can be locked at the front end of the guide rail is provided. An operating crank that can be engaged and disengaged with the locking mechanism is provided at a rear end of the storage of the frame bracket. A lock mechanism that can be fixed to the end.

In a third aspect based on the second aspect, the locking mechanism includes a rod pin inserted into a hole provided at a front end of the guide rail.

In a fourth aspect based on the second aspect, the lock mechanism includes an operating crank, a frame bracket, and a pin inserted into the guide rail.

[0012]

According to the first aspect of the present invention, the front end of the pallet storage is fixed to the back of the battery chamber, and the rear end of the pallet storage is fixed to the entrance side of the battery chamber. Therefore, the harness is not damaged and the terminal is not loosened due to the movement of the pallet, the good function of the battery can be maintained, and the fixing of the pallet storage front end can be remotely controlled.

According to the second aspect of the present invention, the front end of the pallet for storing the frame bracket is located at the front end of the guide rail, which is the back of the battery chamber, and the rear end of the pallet for storing the frame bracket is located at the entrance side of the battery chamber. The pallet is fixed to the rear end of the guide rail, so that the pallet does not move due to vibration etc. while the vehicle is running, and the harness is not damaged or the terminal is not loosened. Since the fixing and releasing can be operated on the side, the operation can be easily performed.

According to the third and fourth aspects, the fixing can be performed by a simple structure.
