At this time, the battery mounting part 500 of the electric vehicle is in the same vertical line as the battery removal part of the mobile device due to various factors, for example, a difference in tire pressure, a passenger's tendency, and a driver's difficulty in stopping the electric vehicle to the correct replacement position. There are many cases where they will be located in a position slightly displaced without being located at.

Therefore, even if the battery 400 and the battery mounting part 500 held by the battery detachable part are not located on the same vertical line but positioned slightly different from each other, if the misaligned position falls within a predetermined error range, the battery detachable part may fall. It is possible to mount the battery mounting portion 500 of the battery 400.

Of course, in this case, if the displaced position of the battery detachment unit and the battery mounting unit 500 holding the battery 400 is outside the preset error range, the battery detachment unit does not descend and stops again so that the bus enters the error range again. You will have to go through the process.

As described above, the battery detachable portion holding the battery 400 and the battery mounting portion 500 are in a state in which they are displaced within an error range, so that the movable rail descends in the Z-axis direction with respect to the variable guide rail, and the bottom surface of the battery 400 If the part circumference is located inside the guide piece 530 installed at each corner side of the battery mounting part 500 and at least one part is in contact, the battery detaching part releases the battery 400 held by the battery to its own weight.

Each of the guide pieces 530 is also formed with an inclined surface 532 so that the cross-sectional area connecting the upper end thereof is larger than the cross-sectional area of the bottom surface of the battery, so that the battery 400 is equal to the battery mounting part 500. Even if it is inclined or twisted within a predetermined error range with respect to the shipboard, it is possible to pull in and accurate settings are made.

In addition, since the tip gap of the cone recess 510 of the battery mounting unit 500 is formed to be relatively narrower than the inlet end of the cone recess 420 of the battery 400, the insertion is easily performed.

Subsequently, when the battery 400 is seated in the correct position on the bottom portion 502 of the battery mounting portion 500, the grip holder 520 of the battery mounting portion 500 is pinched inwardly by the power means and is placed vertically. As a result, the stepped portion 522 of the grip holder 520 is positioned in a horizontal direction on the upper portion of the lower locking jaw 412 of the cutout groove 410 of the battery 400, thereby being locked. Will bind Shanghai East.

In the above description, a process of mounting the battery 400 to the battery mounting part 500 in a state where the battery detachable part holding the battery 400 and the battery mounting part 500 are shifted within an error range based on the same vertical line will be described. And, the process of removing the battery 400 mounted on the battery mounting unit 500 as the battery detachment unit has not been described in detail, for the reason that the battery detachment portion is closed in the open state of the grip portion of the battery 400 cut groove 410, since only the upper locking jaw 414 is to be made, it is because there is no problem to pick up even if it is not located on the same vertical line if it is within the error range.

Therefore, the detachable device of the battery for the electric vehicle according to the second embodiment of the present invention can also easily exchange the discharge battery of the bus 2 with the buffer battery mounted on the battery stand of the mounting table in a short time.
