Abstract

An electrically power assisted vehicle such as a bicycle and specifically a rechargeable battery holding arrangement for such vehicles. The vehicle is provided with a battery box that defines an internal opening for receiving a battery carrier and at least one battery carried thereby. A lid of the battery box carries a spring biased member engageable with the battery carrier for holding the battery carrier in the battery box when the lid is closed. Terminals are provided on the battery carrier and the battery box with the later terminal being disposed in the cavity so that the electrical connection to the vehicle is protected whether or not the battery carrier is in place.

Claims

1. A battery arrangement for an electrically powered vehicle comprised of a battery box adapted to be affixed to said vehicle and defining an internal cavity closed by a selectively operable lid, a first electrical terminal disposed within said internal cavity and connected externally of said battery box to an electric motor of the vehicle, and a battery carrier containing at least one battery detachably received in said cavity, said battery carrier having a second terminal electrically connected to the battery contained thereof and engageable with said first terminal for establishing an electrical connection therebetween solely upon receipt of said battery carrier in said cavity.

2. A battery arrangement for an electrically powered vehicle as set forth in claim 1, wherein the lid is pivotally supported on the battery box.

3. A battery arrangement for an electrically powered vehicle comprised of a battery box adapted to be affixed to said vehicle and defining an internal cavity closeable by a selectively operable lid pivotally supported on said battery box, a first electrical terminal disposed within said internal cavity and connected externally of said battery box to an electric motor of the vehicle, and a battery carrier containing at least one battery detachably received in said cavity, said batter carrier having a second terminal electrically connected to the batter contained thereof and engageable with said first terminal for establishing an electrical connection therebetween when said batter carrier is received in said cavity, said lid carrying a spring biased pressing member engageable with the battery carrier when said lid is closed for urging said first and said second terminals into their electrical connection.

4. A battery arrangement for an electrically powered vehicle as set forth in claim 3, wherein the battery carrier is provided with a pivotally supported handle for carrying of the battery carrier.

5. A battery arrangement for an electrically powered vehicle as set forth in claim 4, wherein the spring biased member carried by the lid is engageable with the handle of the battery carrier for further retaining the handle in a storage position when the battery carrier is contained within the battery box and the lid is in its closed position.

6. A battery arrangement for an electrically powered vehicle as set forth in claim 5, wherein the battery carrier is provided with a third terminal for receiving a charging electrical power source for charging the battery contained within said battery carrier.

7. A battery arrangement for an electrically powered vehicle as set forth in claim 6, wherein the battery box is provided with a selectively closeable opening aligned with the third terminal of the battery carrier when said battery carrier is received in said cavity for charging of the battery carried by said battery carrier without removing said battery carrier from said battery box.

8. A battery arrangement for an electrically powered vehicle comprised of a batter box adapted to be affixed to said vehicle and defining an internal cavity closeable by a selectively operable lid, a first electrical terminal disposed within said internal cavity and connected externally of said battery box to an electric motor of the vehicle, a battery carrier containing at least one battery detachably received in said cavity, said battery carrier having a second terminal electrically connected to the battery contained thereof and engageable with said first terminal for establishing an electrical connection therebetween when said battery carrier is received in said cavity, and said battery carrier being provided with a third terminal for receiving a charging electrical power source for charging the battery contained within said battery carrier, and when said first and said second terminals are electrically connected.

9. A battery arrangement for an electrically powered vehicle as set forth in claim 8, wherein the battery box is provided with a selectively closeable opening aligned with the third terminal of the battery carrier when said battery carrier is received in said cavity for charging of the battery carried by said battery carrier without removing said battery carrier from said battery box.

10. A battery arrangement for an electrically powered vehicle comprised of a battery box adapted to be affixed to said vehicle and defining an internal cavity closeable by a selectively operable lid, a first electrical terminal disposed within said internal cavity and connected externally of said battery box to an electric motor of the vehicle, and a battery carrier containing at least one battery detachably received in said cavity, said battery carrier having a second terminal electrically connected to the battery contained thereof and engageable with said first terminal for establishing an electrical connection therebetween when said battery carrier is received in said cavity, said vehicle being comprised of a bicycle having a frame assembly, a front wheel dirigibly supported at a forward end of said frame assembly, a driven wheel supported for rotation at the rear end of said frame assembly, said frame assembly providing a seat pillar carrying a seat for accommodating a rider, said battery box being disposed on one side of said seat pillar with the cavity thereof being disposed at least in part beneath said seat.

11. A battery arrangement for an electrically powered vehicle as set forth in claim 10, wherein the battery box is disposed behind the seat pillar.

12. A battery arrangement for an electrically powered vehicle as set forth in claim 10, wherein the lid is pivotally supported on the battery box.

13. A battery arrangement for an electrically powered vehicle as set forth in claim 12, wherein the lid carries a spring biased pressing member engageable with the battery carrier when said lid is closed for urging said first and said second terminals into their electrical connection.

14. A battery arrangement for an electrically powered vehicle as set forth in claim 13, wherein the battery carrier is provided with a pivotally supported handle for carrying of the battery carrier.

15. A battery arrangement for an electrically powered vehicle as set forth in claim 14, the spring biased member carried by the lid is engageable with the handle of the battery carrier for further retaining the handle in a storage position when the battery carrier is contained within the battery box and the lid is in its closed position.

16. A battery arrangement for an electrically powered vehicle as set forth in claim 15, the battery carrier is provided with a third terminal for receiving a charging electrical power source for charging the battery contained within said battery carrier.

17. A battery arrangement for an electrically powered vehicle as set forth in claim 16, wherein the battery box is provided with a selectively closeable opening aligned with the third terminal of the battery carrier when said battery carrier is received in said cavity for charging of the battery carried by said battery carrier without removing said battery carrier from said battery box.

18. A battery arrangement for an electrically powered vehicle as set forth in claim 10, wherein the battery carrier is provided with a third terminal for receiving a charging electrical power source for charging the battery contained within said battery carrier.

19. A battery arrangement for an electrically powered vehicle as set forth in claim 18, wherein the battery box is provided with a selectively closeable opening aligned with the third terminal of the battery carrier when said battery carrier is received in said cavity for charging of the battery carried by said battery carrier without removing said battery carrier from said battery box.
