[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0026] Some embodiments of the present application will be described in detail. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] Embodiment

[0028] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides an outboard motor 1 for an electric boat, which includes an outboard main body 11, a battery assembly 12, and a motor propeller 13. The outboard main body 11 extends along the vertical direction, and the outboard main body 11 is provided with a receiving cavity 111. The battery assembly 12 is disposed in the receiving cavity 111. The motor propeller 13 is disposed at the bottom of the outboard main body 11, and the motor propeller 13 is electrically connected to the battery assembly 12. When the outboard main body 11 is operating, the motor propeller 13 extends into the water, and the rotation of the motor propeller 13 causes the water to flow to take away the heat of the battery assembly 12.

[0029] In the outboard motor 1 of this embodiment, by disposing the battery assembly 12 in the receiving cavity 111 of the outboard main body 11, the battery assembly 12 provides power for the rotation of the motor propeller 13, and the rotation of the motor propeller 13 causes the water to flow to take away the heat of the battery assembly 12, thereby reducing the temperature of the battery assembly 12 during operation. Therefore, the outboard motor 1 of this embodiment has a compact structure to optimize the occupied space of the battery assembly 12.

[0030] In this embodiment, the motor propeller 13 and the battery assembly 12 are disposed on the outboard main body 11, thereby reducing the length of the wire harness connecting the motor propeller 13 and the battery assembly 12.

[0031] In a possible embodiment, the battery assembly 12 includes a battery cell 121, a BMS board 122, and a drive board 123. The drive board 123 is disposed at a position in the receiving cavity 111 close to the motor propeller 13. The drive board 123 is electrically connected to the motor propeller 13. The battery cell 121 is disposed in the middle of the receiving cavity 111. The BMS board 122 is disposed between the battery cell 121 and the drive board 123. One end of the BMS board 122 is connected to the battery cell 121, and the other end is connected to the drive board 123.

[0032] A large amount of operations and signal control are performed by the BMS board 122 and the drive board 123 during operation, so a lot of heat will be generated. In the outboard motor 1 of this embodiment, by disposing the BMS board 122 and the drive board 123 at a position in the receiving cavity 111 close to the motor propeller 13, the rotation of the motor propeller 13 causes the water to flow to take away the heat of the BMS board 122 and the drive board 123, thereby reducing the temperature of the BMS board 122 and the drive board 123 during operation. Therefore, the battery assembly 12 does not need to add a heat dissipation device to optimize the occupied space of the battery assembly 12.

[0033] In a possible implementation, there are multiple battery cells 121, and the multiple battery cells 121 are stacked along the vertical direction.

[0034] In this embodiment, the outer machine body 11 extends along the vertical direction, and the multiple battery cells 121 are stacked along the vertical direction in the accommodation cavity 111, so that the battery assembly 12 is structurally compact to optimize the space occupied by the battery assembly 12.

[0035] In a possible implementation, the BMS board 122 and the drive board 123 are respectively fixedly connected to the outer machine body 11, and the battery cells 121 are detachably arranged in the accommodation cavity 111.

[0036] In this embodiment, the positions of the BMS board 122 and the drive board 123 are fixed. When the battery cells 121 need to be maintained, the battery cells 121 are disassembled for replacement or repair. Such a setting makes the outboard motor 1 of the electric boat not only structurally compact and stable but also easy to repair.

[0037] In a possible implementation, the outboard motor 1 of the electric boat further includes a cover member 14. An opening 112 is provided at one end of the accommodation cavity 111 away from the motor propeller 13, and the cover member 14 is arranged at the opening 112.

[0038] In this embodiment, the outboard motor 1 of the electric boat performs maintenance on the battery cells 121 by opening the cover member 14 and accessing the battery cells 121 from the opening 112. Such a setting makes the battery cells 121 not only structurally compact but also easy to repair.

[0039] In a possible implementation, the cover member 14 includes a top cover 141 and a cover body 142. The top cover 141 is rotatably connected to the cover body 142. The cover body 142 corresponds to the opening 112, and the cover body 142 is connected to the outer machine body 11 to close the opening 112.

[0040] In this embodiment, the cover body 142 closes the opening 112 to prevent water from entering the interior of the accommodation cavity 111 and damaging the battery assembly 12. The cover body 142 is used for waterproofing and protecting the battery assembly 12 in the accommodation cavity 111. The outboard motor 1 of this embodiment charges the battery cells 121 by providing a fast charging interface on the cover body 142. The top cover 141 is rotatably connected to the cover body 142 to cover the fast charging interface, and the top cover 141 is used for protecting the fast charging interface. Such a setting makes the outboard motor 1 of the electric boat not only structurally compact but also have better waterproof performance.

[0041] In a possible implementation, the outboard motor 1 of the electric boat further includes a steering member 15. The steering member 15 includes a steering motor 151 and a steering rudder 152. The steering motor 151 is fixed to the outer machine body 11, and the rotating shaft of the steering motor 151 is connected to the steering rudder 152. The steering motor 151 is used to drive the steering rudder 152 to swing.

[0042] The steering component 15 is arranged on one side of the outer machine main body 11 opposite to the motor propeller 13. In the outboard motor 1 of this embodiment, the steering motor 151 controls the swing of the steering rudder 152, so that the operation controllability of the steering rudder 152 is better and the structure is more compact.

[0043] In a possible implementation manner, the outboard motor 1 of the electric boat further includes a hoop 16. The hoop 16 is sleeved on the circumferential surface of the outer machine main body 11 and fixedly connected to the outer machine main body 11. One end of the hoop 16 is fixedly connected to the steering motor 151, and the other end is movably connected to the steering rudder 152.

[0044] In this embodiment, the outboard motor 1 of the electric boat fixedly connects the outer machine main body 11 and the steering component 15 through the hoop 16. The hoop 16 is used to fix the steering motor 151, so that the steering motor 151 can better control the swing of the steering rudder 152 to adjust the water flow direction, thereby adjusting the direction.

[0045] The above embodiments are only used to illustrate the technical solutions of the present application rather than to limit them. Although the present application has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
