Abstract

A battery changing system is provided for an electrically powered vehicle. The battery changing system includes a housing for the battery. The housing includes first and second spaced crossbars. A battery manipulating mechanism is mounted to the vehicle. This battery manipulating mechanism includes at least one outwardly projecting arm that is pivotally connected to the vehicle and driven by an actuator so as to raise and lower the battery. More specifically, the arm includes an upwardly directed recess for engaging the first crossbar on the battery housing and a downwardly directed saddle for receiving the second crossbar of the battery housing. A locking plate may be selectively extended to secure the second crossbar in the saddle.

Claims

1. A battery changing system for an electrically powered vehicle, comprising:

a housing for a battery including first and second spaced engagement points;

a battery manipulating arm mounted to the vehicle for raising and lowering said battery, said battery manipulating arm including means for engaging said first and second engagement points on said battery housing, a recess for receiving said first engagement point and a saddle for receiving said second engagement point, said recess and said saddle having entryways opening in substantially opposite directions; and

means mounted to one of said battery manipulating arm and said battery housing for locking together said engaging means on said battery manipulating arm and said second, spaced engagement point on said battery housing.

2. The battery changing system set forth in claim 1, wherein said first and second spaced engagement points comprise first and second spaced crossbars.

3. The battery changing system set forth in claim 2, wherein said first and second spaced crossbars bridge a channel formed in said housing.

4. The battery changing system set forth in claim 3, wherein said battery manipulating arms includes a proximal end and a distal end, said arm being pivotally connected to said vehicle adjacent said proximal end.

5. The battery changing system set forth in claim 4, wherein said recess is adjacent said distal end and said saddle is relatively closer to said proximal end of said battery manipulating arm.

6. The battery changing system set forth in claim 1, wherein said battery manipulating arm further includes an actuator pivotally connected between the vehicle and said arm closer to said distal end than said proximal end.

7. The battery changing system set forth in claim 6, wherein said locking means comprises a locking plate and a locking plate actuator, said locking plate being selectively displaceable across at least a portion of said entryway to said saddle.

8. An electrically powered vehicle incorporating the battery changing system set forth in claim 1.

9. An electrically powered vehicle incorporating the battery changing system set forth in claim 4.

10. An electrically powered vehicle incorporating the battery changing system set forth in claim 7.

11. An electrically powered vehicle incorporating the battery changing system set forth in claim 2.

12. An electrically powered vehicle incorporating the battery changing system set forth in claim 3.
