Description

[Detailed Description of the Invention] The invention is based on the fact that the storage capacity of the battery that is mounted on the luggage carrier as a power source for the travel drive motor, various control circuits, and controlled drive machines in addition to the power supply for the luggage transport trolley is running low. This invention relates to a battery transfer device that can be used for one month when replacing a battery that is about to end its discharge with a fully charged battery.

The conventional battery transfer device is equipped with a movable frame that can be driven and reciprocated in a direction near and far with respect to the battery or battery case mounted on a trolley, and a portion of the movable frame corresponding to the center of the battery or batch 17-case is provided. 1lt
Ji'fe can be freely engaged and disengaged from the locking part of the battery or battery case, and when the movable frame is in its locked state, it can be moved away from or approached by a pulling force and pushing force in the same direction as this moving direction. A locking claw is provided to apply force to the battery case, but this has the following drawbacks.

That is, in order to push and pull the central part of the battery or battery case with one locking pawl, when pushing the battery or battery case into a predetermined position on the trolley, the battery or battery case is pressed on both sides in the l] direction. If there is even a slight difference in push-in resistance, it is inevitable that the posture of the battery or battery case will gradually change as the locking claw is pushed in, and as a result, the terminals on the battery or battery case side and the terminals on the trolley side will inevitably change. The disadvantages are that the connection with the battery may become uncertain, or the battery or battery case may collide with the battery or battery case storage section on the trolley side, resulting in deformation or damage to the component parts. has the aim of improving the above-mentioned drawbacks.

In order to achieve this purpose, the uninvented battery transfer device has a movable frame that can be driven and reciprocated in the far and near directions with respect to the parallel or battery case mounted on the luggage carrier. In preparation, this movable frame,
A part corresponding to the center of the battery or battery case is attached to and detachable from the locking part of the battery or battery case, and when the movable frame is moved apart in the attached state, a part on the C9 trolley is attached. A locking pawl is provided to take out the battery or battery case, and at a symmetrical or almost symmetrical position vcta on both sides of the left stone of the locking pawl, the battery or battery case is moved close to the 11tU frame on a trolley. A suppressing member is provided that is pushed into a predetermined position on the top.
The point is that

In other words, when removing the batch IJ on the trolley just before the end of discharge or the entire battery case, the entire 11J central part of the battery or battery case is pulled out using one locking claw, so there is resistance to pulling out on both sides of the width of the battery or battery case. Even if there is a difference, this battery or TR,
r The battery case can be pulled out in almost a predetermined posture, and when a fully charged battery or battery case is pushed into a predetermined position on the trolley [(r3.,
Since the battery or battery case is pushed in using the pressing members provided at symmetrical positions of the locking claws, even if there is a difference in pushing resistance on both sides of the battery or battery case in the width direction, the entire battery or battery case will be You can push it in a flat position.

Therefore, the transfer work when replacing the battery can be carried out reliably while avoiding troubles such as poor connection of terminals, deformation and damage of component parts, and moreover, as mentioned above, it is possible to carry out the transfer work when replacing the battery or U battery case. Since this is done with a pressing member, the conventional W method uses locking claws to push and pull the battery or battery case.
Compared to Rff, the number of operations required to switch the locking pawl between the locked state and the unlocked state is reduced to about half, and this can also contribute to improving transfer work efficiency.
