Abstract:
The present invention relates to an apparatus for automatically opening and closing a door for a battery of a vehicle. The present invention automatically opens and closes a first door (50) and a second door (50′) for opening and closing a battery mounting unit (12) in which a battery (16) is mounted. The first door (50) and the second door (50′) are selectively opened. For example, when the first door (50) is opened, a first and a second roller assembly (60, 60′) are guided to move along a door rail (56) provided in the second door (50′) and a frame rail (40) mounted on a sub frame (22). A curved part (44) is provided on an end of the frame rail (40) and a curved rail (38) is connected to an end of the door rail (56) so that the doors (50, 50′) move relatively downward in a late stage of the closing of the door (50.50′). According to the described configuration, a space for installing the doors (50, 50′) is minimized by minimizing a space for opening and closing the doors (50, 50′), and the overall height of a door opening and closing apparatus becomes lower since the doors (50, 50′) move to a relatively lower position in the later stage of opening and closing of the doors (50, 50′), therefore a height of the vehicle using the battery can be lowered.
Abstract:
The present invention relates to a battery mounting apparatus for an electric vehicle. The battery mounting apparatus of the present invention allows a plurality of batteries used for electric vehicles to be provided in one battery mounting part (16). First and second inner parts (20, 22), which constitute the floor of the battery mounting part (16), are separately provided, and the first and the second inner parts (20, 22) are reinforced by providing an additional reinforcing frame (30). A connection reinforcement plate (38) is further provided to connect and support the first and the second inner parts (20, 22) where the first and the second inner parts (20, 22) come into contact with each other. The reinforcing frame (30) is supported by a connection support bar (34) on a roof body (12), which constitutes the roof (10) of a vehicle. The connection support bar (34) extends from a reinforcement bar (32) on one side of the reinforcement frame (30) while being inclined downward to a front lower part. According to the present invention, the battery can be more effectively supported even if the battery is heavy, when a plurality of batteries are mounted in the one battery mounting part (16).
