Abstract

A marine drive is for propelling a marine vessel. The marine drive has a propulsor configured to generate a thrust force in a body of water, an electric motor that powers the propulsor, a battery having a battery port for outputting battery power, a supporting frame that supports the marine drive relative to marine vessel, the supporting frame having a frame interior that retains the battery, and a motor port in the frame interior, wherein inserting the battery into the frame interior engages the battery port with the motor port so that the battery provides electric power to the electric motor. A removable cover is provided on the motor port.

First claim

What is claimed is:

1. A marine drive for propelling a marine vessel, the marine drive comprising:
a propulsor configured to generate a thrust force in a body of water,
an electric motor that powers the propulsor,
a battery having a battery port for outputting battery power,
a monolithic supporting frame configured to support the marine drive and also suspend the propulsor relative to marine vessel, the monolithic supporting frame having a frame interior that retains the battery, and
a motor port in the frame interior, wherein inserting the battery into the frame interior engages the battery port with the motor port so that the battery provides electric power to the electric motor.

2. The marine drive according to claim 1 , further comprising a track which guides the battery into the frame interior such that battery port operably engages the motor port when the battery is slid along the track into the frame interior.

3. The marine drive according to claim 2 , further comprising a guide sleeve coupled to the monolithic supporting frame, wherein the track is on the guide sleeve.

4. The marine drive according to claim 1 , further comprising a battery latch that engages the battery with the monolithic supporting frame as the battery is inserted into the frame interior, wherein the battery latch is operable to disengage the battery from the monolithic supporting frame, thus permitting removal of the battery from the frame interior.

5. The marine drive according to claim 4 , wherein the battery latch comprises a latch finger and an engagement recess that is engaged by the latch finger when the battery is fully inserted into the frame interior.

6. The marine drive according to claim 5 , wherein the latch finger is on the battery and the engagement recess is in the frame interior, and further comprising a ramp on the monolithic supporting frame, the ramp being engaged by the latch finger as the battery is inserted into the frame interior so as to push the latch finger into the battery, and
wherein the latch finger is spring biased out of the battery when the latch finger becomes aligned with the engagement recess, so as to engage the battery with the monolithic supporting frame.

7. The marine drive according to claim 5 , further comprising a latch actuator that is operable to move the latch finger out of engagement with the engagement recess, thus permitting removal of the battery from the frame interior.

8. The marine drive according to claim 4 , further comprising a battery removal assist mechanism in the frame interior,
wherein unlatching the battery from the monolithic supporting frame moves the battery port out of engagement with the motor port.

9. The marine drive according to claim 1 , further comprising a cowling on the monolithic supporting frame, the cowling having a first cowl portion and a second cowl portion which is movable relative to the first cowl portion into a closed position enclosing the monolithic supporting frame and the battery in a cowling interior and into an open position providing access to the cowling interior for insertion and removal of the battery.

10. The marine drive according to claim 9 , further comprising a motor port cover configured to prevent environmental wear or damage of the motor port, the motor port cover being mountable in a use position on the motor port and alternatively being mountable in a storage position on an interior surface of the cowling.

11. The marine drive according to claim 10 , further comprising a pedestal on the interior surface of the cowling, the pedestal being configured to retain the motor port cover in the storage position.

12. The marine drive according to claim 11 , wherein the interior surface of the cowling is on the second cowl portion.

13. The marine drive according to claim 12 , wherein the motor port cover comprises a cover body which engages the pedestal in a friction fit and wherein the cover body also engages the motor port in a friction fit.

14. The marine drive according to claim 13 , further comprising seals on the pedestal and on the motor port for preventing ingress of debris and fluid.

15. The marine drive according to claim 14 , wherein the pedestal and the motor port have an identical outer perimeter shape and size.

16. The marine drive according to claim 10 , further comprising a tether that couples the motor port cover to the monolithic supporting frame.

17. The marine drive according to claim 1 , further comprising a motor port cover for the motor port, the motor port cover being movable into a use position in which the motor port cover prevents environmental wear or damage of the motor port and a non-use position in which the battery port is connectable to the motor port.

18. The marine drive according to claim 17 , wherein inserting the battery into the frame interior causes the motor port cover to move from the use position to the non-use position.

19. The marine drive according to claim 17 , further comprising a lever assembly for moving the motor port cover into the non-use position,
wherein inserting the battery into the frame interior operably engages the lever assembly so as to move the motor port cover from the use position to the non-use position.

20. The marine drive according to claim 19 , wherein the lever assembly comprises a lever arm that protrudes into the frame interior and is engaged by the battery as the battery is inserted into the frame interior.

21. The marine drive according to claim 20 , wherein the lever assembly further comprises a linkage that operably couples the lever assembly to the motor port cover.

22. The marine drive according to claim 21 , wherein the lever assembly is pivotable, and wherein inserting the battery into the frame interior pivots the lever assembly, which in turn causes the linkage to move the motor port cover from the use position to the non-use position.

23. The marine drive according to claim 19 , wherein the motor port cover is biased by a spring-force into the use position, and
wherein inserting the battery into the frame interior moves the motor port cover against the spring-force into the non-use position and wherein removing the battery from the frame interior permits the spring-force to move the motor port cover into the use position.

24. The marine drive according to claim 23 , further comprising a track which guides the battery into the frame interior.
