The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Some embodiments of the present application are described in detail. In the following embodiments, features of the embodiments may be combined with each other without conflict.

Examples

Referring to fig. 1, the present embodiment provides a marine vessel 300 including a hull 310 and an outboard motor 100.

The hull 310 may have a structure with a large buoyancy such that the ship 300 floats on the water surface P1 as a whole. The hull 310 may be used to carry people or items. The draft H of the hull 310 varies with different bearing weights.

The outboard motor 100 is mounted to the hull 310 and is used to provide power to propel the watercraft 300.

In this embodiment, the outboard motor 100 includes an outboard motor main body 10, a clamp 20, and a driving part 30.

Wherein the clamp 20 is for mounting to a hull 310. For example, the clamp 20 is fixedly mounted to the aft portion of the hull 310 by fasteners (not shown) such as bolts. The outdoor unit body 10 is movably mounted on the clamp 20, and can partially extend into the water surface P1 and interact with the water to push the ship 300 to move on the water surface P1. The driving portion 30 is connected to the clamp 20 and is drivingly connected to the outer body 10 for driving the whole or a part of the outer body 10 to move relative to the clamp.

The movement of the driving part 30 driving the outdoor unit main body 10 may be used to implement the tilting of the outdoor unit main body 10 to change the posture of the outdoor unit main body 10, thereby changing the pushing direction of the outdoor unit main body 10.

The outdoor unit body 10 includes a first portion S1 and a second portion S2, and the second portion S2 and the first portion S1 are connected in the first direction Z. In the illustrated state, the first direction Z is in the direction of gravity, i.e. perpendicular to the water surface P1, and the first portion S1 is located below the second portion S2, and enters below the water surface P1 when necessary, for acting with the water to provide propulsion, for example by providing a propeller 13b on the first portion S1 to achieve interaction with the water. It should be understood that the first direction Z is only used as a reference direction, and is not a limited direction of the structure of the outboard motor body 10, and in a certain operation state of the outboard motor 100, there is a state as shown in the figure, that is, in other operation states of the outboard motor 100, the first direction Z is also inclined to the water surface P1.

The movement of the driving part 30 to move the outer machine body 10 includes the movement of the first portion S1 and the movement of the second portion S2. The motion of the first part S1 has at least a component in a first direction Z, and the motion of the second part S2 has a component in a second direction X, which is perpendicular to the first direction Z and parallel to the water surface P1 in the illustrated state, which is zero, and points in the fore-and-aft direction of the vessel 300.

Referring to fig. 2 in conjunction, for convenience of description, the movement of the first portion S1 is represented by a first vector Y1, and the movement of the second portion S2 is represented by a second vector Y2.

The movement of the first portion S1 has a first directional component Y11 in the first direction Z, the first directional component Y11 being the component of the first vector Y1 in the first direction Z, the movement of the first portion S1 has a second directional component Y12 in the second direction X, the second directional component Y12 being the component of the first vector Y1 in the second direction X. As described hereinbefore, the movement of the first portion S1 has a first directional component Y11, i.e. the first directional component Y11 is non-zero, indicating that the driving portion 30 has the ability to move the first portion S1 in the first direction Z; the second direction component Y12 may be zero or non-zero, and is not limited. When the second direction component Y12 is zero, the first portion S1 is driven by the driving portion 30 to move along the first direction Z, which may be a vertical lifting movement; when the second direction component Y12 is non-zero, the first portion S1 is moved in a manner that is a combination of the first direction component Y11 and the second direction component Y12, possibly as a rotational movement of the first portion S1 in a longitudinal plane defined by the first direction Z and the second direction X.

The component of the movement of the second portion S2 in the second direction X is zero, i.e. the second vector Y2 is equal to its component Y21 in the first direction Z. When the value of the component Y21 of the movement of the second portion S2 in the first direction Z is also zero, the second portion S2 remains stationary relative to the hull 310, and the driving portion 30 does not drive the second portion S to move relative to the hull 310; when the component Y21 of the motion of the second portion S2 in the first direction Z takes on a value different from zero, the second portion S2 will move in the first direction Z under the driving action of the driving portion 30.

Some exemplary implementations are given below. In the embodiment shown in fig. 3 to 7, the first portion S1 and the second portion S2 are relatively stationary and have an equal first direction component Y11 (not 0), and neither has the second direction component Y12 (or the second direction component Y12 is 0), which is embodied as that the entire external machine body 10 slides and ascends along the first direction Z (as the aforementioned sliding direction) relative to the clamp 20, so as to realize the integral lifting and raising. In the embodiment shown in fig. 8 and 9, the components of the second portion S2 in the first direction Z and the second direction X are both 0, that is, the second portion S2 is not displaced relative to the clamp 20 (but is not limited to being able to rotate about the self-axis relative to the clamp), and both the first direction component Y11 and the second direction component Y12 of the first portion S1 are not zero, that is, the portion (referred to as the first portion S1) of the outer machine body 10 is able to rotate about the relative rotation axis (as the aforementioned rotation axis direction) of the first portion S1 and the second portion S2 relative to the clamp 20, so as to achieve the lift. Wherein, the sliding direction, the rotating shaft direction and the main shaft axis direction of the propeller 13b are perpendicular to each other.

Referring to fig. 3, the outboard motor body 10 of the outboard motor 100 according to the present embodiment includes a head 11 and a coupling shaft 12. The propeller 13b may be driven by a first motor 13 a. The first motor 13a is connected with the propeller 13b in a transmission manner to form a propeller assembly 13, and the first motor 13a is used for driving the propeller 13b to rotate so as to generate thrust.

When the outboard motor 100 is operated in the illustrated state, the connecting shaft 12 extends along the first direction Z, that is, the axial direction of the connecting shaft 12 is the first direction Z. In the present embodiment, a section of the connecting shaft 12 near the propeller assembly 13 is defined as a first shaft section 12a, and a section near the handpiece 11 is defined as a second shaft section 12b. For example, a section P2 perpendicular to the first direction Z is defined, the first shaft section 12a is a portion of the connecting shaft 12 on a side of the section P2 close to the propeller assembly 13, and the second shaft section 12b is a portion of the connecting shaft 12 on a side of the section P2 close to the handpiece 11. The position of the cross section P2 may be set as needed. In this embodiment, the first shaft section 12a and the second shaft section 12b may be a complete shaft, or may be two shafts fixedly connected by a connecting member, and the connecting member may be a screw, a pin, a bolt, or other devices, which is not limited herein, and only needs to keep the relative positions of the first shaft section 12a and the second shaft section 12b unchanged under the driving of the driving portion 30. In this embodiment, the portion of the connecting shaft 12 adjacent to the handpiece 11 (i.e., the second shaft section 12 b) and the handpiece 11 constitute the aforementioned second portion S2, and the portion of the connecting shaft 12 adjacent to the propeller assembly 13 (i.e., the first shaft section 12 a) and the propeller assembly 13 constitute the aforementioned first portion S1. Therefore, in this embodiment, the first portion S1 and the second portion S2 are fixedly connected to each other by the first shaft segment 12a and the second shaft segment 12b in an integrated manner.

In this embodiment, the handpiece 11 and the propeller assembly 13 are respectively connected to the two axial ends of the connecting shaft 12.

The handpiece 11 includes a housing 11b, and the internal space 11c of the housing 11b may be used for accommodating other structures, such as a controller 14 for controlling the operation of each motor, which will be described later, or a bracket for fixing the controller 14, and a wire harness electrically connected to the controller 14, where the structural components accommodated inside the housing 11b are not limited to the parts described in the embodiment.

The propeller assembly 13 is located at an end of the connecting shaft 12 remote from the head 11, is connected to the first shaft section 12a, and can be located under water for interacting with water to generate propulsion force when the outboard motor 100 is in a position to propel the hull 310 (see fig. 1) for navigation. For example, in the present embodiment, the propeller assembly 13 is used for obtaining the propulsive force, and includes a first motor 13a and a propeller 13b, wherein the first motor 13a is disposed on the first portion S1, such as the lower end of the first shaft section 12 a. The first motor 13a is in transmission connection with the propeller 13b and can drive the propeller 13b to rotate so as to act with water to generate driving force.

In the embodiment of the present application, the first motor 13a may be a single stator motor, a double stator motor (a motor having two stators and one or two rotors), or another type of motor (e.g., a reduction motor with a built-in speed reducer).

In the embodiment of the present application, the propeller 13b may be a contra-rotating propeller, a ducted propeller, or another type of propeller.

It will be appreciated that the first portion S1 is fixedly connected to the second portion S2. The driving portion 30 drives the connecting shaft 12 to move along the first direction Z, so that the first portion S1 and the second portion S2 move synchronously along the first direction Z, and the propeller assembly 13 is driven to move along the first direction Z. In one state, the connecting shaft 12 drives the propeller assembly 13 to move in the first direction Z and sink into the water, so that the outboard motor 100 can push the hull 310 to sail. In another state, the connecting shaft 12 drives the propeller assembly 13 to move away from the water surface along the first direction Z, so that the outboard motor 100 stops pushing the hull 310, the hull 310 can be in the parking state, and the propeller assembly 13 is prevented from contacting with the water, thereby prolonging the service life of the propeller assembly 13. Because the nose 11 only moves in the first direction Z, the nose 11 does not move close to the side of the hull 310, that is, the nose 11 does not encroach on the space of the hull 310, so that the hull 310 can obtain more usable space, and the boat-navigating experience is improved.

Referring to fig. 4, in another embodiment, the first motor 13a may be disposed at a middle position of the connecting shaft 12 in a longitudinal direction, and transmits power to the propeller 13b through a transmission structure 13c (e.g., a bevel gear set, a belt transmission mechanism, a chain transmission mechanism, etc.) connected between the first motor 13a and the propeller 13b. When the connecting shaft 12 is a hollow shaft, the transmission structure 13c may occupy a space inside the connecting shaft 12.

The head 11 is located above the connecting shaft 12 and is connected to the second shaft section 12b. The head 11 may be positioned relatively up on the hull 310 to facilitate handling by the vessel operator. Optionally, an operating rod 11a is disposed on the machine head 11, so that an operator can assist in supporting the external machine body 10 when the external machine body 10 moves.

It is to be understood that the position of the first motor 13a in the middle of the connecting shaft 12 is not limited to the illustrated state, for example, the output shaft of the first motor 13a is disposed along the first direction Z. The connecting shaft 12 is provided with a middle cavity, and the first motor 13a is accommodated in the middle cavity. In the embodiment of the present application, the structural form of the connecting shaft 12 is not limited to the illustrated form, and a frame capable of supporting a motor, a driver, a propeller, and the like may be equivalent to the connecting shaft 12 of the embodiment of the present application.

Referring to fig. 5, in another embodiment, a first motor 13a for driving the propeller 13b may also be provided at the head 11. In order to realize transmission, a transmission structure 13d may be disposed on the connection shaft 12, and the first motor 13a is in transmission connection with the propeller 13b through the transmission structure 13d, for transmitting the rotation torque of the first motor 13a to the propeller 13b. The specific structure of the transmission structure 13d may be configured as required, for example, a gear transmission, a belt transmission, a worm gear transmission, or any other suitable transmission method, which is not limited herein.

In this embodiment, the outboard motor 100 may further include a controller 14, and the controller 14 is electrically connected to the first motor 13a, and is configured to control the operation of the first motor 13a, such as controlling the operation speed and the rotation direction. The controller 14 may be provided to the head 11 or the second shaft section 12b to facilitate maintenance or adjustment.

In the case where the controller 14 and the first motor 13a are located at different positions of the connecting shaft 12, the controller 14 and the first motor 13a may communicate with each other through short-range wireless communication (e.g., bluetooth) or wired communication. When the wired communication is adopted, the connecting shaft 12 can be set as a hollow shaft or provided with a communication channel to realize wiring.

In the present embodiment, the connection shaft 12 is slidably fitted to the jig 20 in the first direction Z. For example, in the present embodiment, the jig 20 is provided with the fitting hole K1 penetrating in the first direction Z, the linear guide 24 is provided inside the fitting hole K1, and the connecting shaft 12 is inserted through the fitting hole K1 and slidably fitted to the linear guide 24. The linear guide 24 may be a roller linear guide, a cylindrical linear guide, a ball linear guide or other structures capable of guiding a linear sliding motion.

In some embodiments, the linear guide 24 is a ball linear guide, and in this case, the connecting shaft 12 can also rotate relative to the clamp 20, so as to steer the ship 300, and in this case, the first portion S1 and the second portion S2 of the external machine body 10 can integrally rotate relative to the rotation axis Z1 parallel to the first direction Z, so as to change the direction of the thrust of the propeller assembly 13.

In other embodiments, the linear guide 24 may be omitted, and the relative sliding fit and the selective relative rotation may be achieved directly through the shaft hole fit between the connecting shaft 12 and the fitting hole K1.

As described above, the driving portion 30 of the present embodiment is mounted on the holder 20 and is drivingly connected to the outer machine body 10 for moving the outer machine body 10 in whole or in part.

As shown in fig. 3, for example, the driving portion 30 includes a second motor 31 and a transmission mechanism 32.

The second motor 31 includes a fixed portion 31a and an output shaft 31b, the fixed portion 31a being mounted on the jig 20, the output shaft 31b being capable of being driven to rotate to output a rotational torque when the second motor 31 is energized. The transmission mechanism 32 is configured to transmit the rotational torque output by the output shaft 31b to the external machine body 10, and is configured to drive the external machine body 10 to ascend and descend along the first direction Z. That is, in the movement of the outdoor unit main body 10 of the present embodiment, the first portion S1 and the second portion S2 move synchronously along the first direction Z, which is represented by the first vector Y1 and the second vector Y2 being equal, and the components of the first vector Y1 and the second vector Y2 in the first direction Z, i.e., the components of the first vector Y1 and the second vector Y2 in the second direction X, being equal to zero.

In the present embodiment, various possible transmission mechanisms 32 can be adopted to realize the transmission of the output torque of the second electric machine 31.

For example, the first rack 12m is connected to the connecting shaft 12, and the first rack 12m extends in the first direction Z. The length of the first rack gear 12m may be determined according to a height at which the outdoor unit body 10 needs to be lifted. The second motor 31 is mounted on the clamp 20, and is connected to the first rack 12m through a transmission mechanism 32, and is configured to drive the first rack 12m and the connecting shaft 12 to move along the first direction, and further drive the entire external machine body 10 to move along the first direction Z through the connecting shaft 12.

The driving portion 30 further includes a lifting controller 301, and the lifting controller 301 may be fixed with the second motor 31, that is, the lifting controller 301 may be fixed on the clamp 20 and electrically connected to the second motor 31. The lift controller 301 is configured to receive a control instruction of the controller 14, and control the rotation speed and the acceleration of the second motor 31 based on the control instruction of the controller 14, so that the second motor 31 can drive and output a target rotation torque according to the input rotation speed and acceleration, and the first portion S1 moves to a target position according to the target rotation torque output by the second motor 31.

In some embodiments, the transmission mechanism 32 may include a worm 32a and a worm wheel 32b engaged with each other, and the output shaft 31b of the second motor 31 is connected to the worm 32a. The worm 32a is disposed coaxially with the output shaft 31 b. The worm 32a is driven to rotate to drive the worm wheel 32b to rotate, and the worm wheel 32b can be directly meshed with the first rack 12m or meshed with the rack through other coaxially connected gear pieces. In this way, the rotation of the output shaft 31b of the second motor 31 can drive the external unit body 10 to move along the first direction Z by the meshing engagement of the worm 32a, the worm wheel 32b and the first rack 12 m. Wherein the worm gear 32b is rotatably mounted to a mounting bracket 21 on the clamp 20. It is to be understood that the layout of the second motor 31 on the jig 20 is not limited to the illustrated form, and as an alternative, for example, the output shaft 31b of the second motor 31 may be arranged in parallel with the connecting shaft.

Referring to fig. 6, in another embodiment, the transmission mechanism 32 may also be implemented by a gear 32d or a gear set (the gear set is an assembly including a plurality of gears 32d in meshing engagement), and the gear 32d or the gear set is connected to the second motor 31 and is meshed with the first rack 12 m. Wherein the gear 32d may be a spur gear, a bevel gear, or other type of gear or combination. When the transmission mechanism 32 uses a single gear 32d, the second motor 31 can be configured to have a larger torque to provide a larger output force to move the outer machine body 10.

In some embodiments, the driving portion 30 further includes a self-locking structure 32p (see fig. 5), and the self-locking structure 32p is connected to the second motor 31 and the transmission mechanism 32, and is configured to lock the transmission mechanism 32 to transmit torque to the outer machine body 10 after the second motor 31 outputs a target torque, so that the outer machine body 10 can be maintained at a certain height position when lifted and tilted. The self-locking structure 32p can be realized by an electromagnetic clutch, a hydraulic clutch, an electromagnetic brake, a mechanical locking device, or the like, or by the second motor 31 with a self-locking function.

When a worm gear with a self-locking function is used as the transmission mechanism 32, an additional self-locking structure 32p may not be provided.

The first rack 12m in this embodiment may extend at an angle, such as 60 degrees, in the circumferential direction of the connecting shaft 12, so that in some embodiments, when the connecting shaft 12 rotates circumferentially relative to the clamp 20 to steer the vessel 300, the meshing engagement between the first rack 12m and the transmission mechanism 32 can still be maintained.

In this embodiment, the driving portion 30 drives the entire external unit body 10 to ascend and descend along the first direction Z without displacement along the second direction X (horizontal direction), so as to avoid the problem that the external unit occupies the space of the ship body in the prior art in the manner that the external unit is inclined integrally and the like (for example, some external units occupy the space of the ship body when inclined toward the side of the ship body in the manner that the external unit is inclined integrally and tilted), and avoid the external unit from compressing the movable space in the ship or interfering with the seat or other structures in the ship. Meanwhile, the outboard motor 100 in the present embodiment can be adapted to different boat types by adjusting the initial position of the outboard motor main body 10 in the first direction Z for different sizes of transoms. In addition, this configuration also facilitates adjusting the draft of the propeller 13b based on the draft of the hull 310 (reaction load condition) to position the propeller 13b in an optimal propulsion position while the vessel 300 is in operation.

When the ship 300 is parked or not used for a long time, the outdoor unit body 10 can be lifted up to separate the outdoor unit body 10 from the water surface P1, so that corrosion or collision damage of the underwater part of the outdoor unit body 10 is reduced.

Fig. 7 shows another exemplary embodiment of the outboard motor 100 in the present embodiment, and the outboard motor 100 is further designed on the basis of the outboard motor 100 shown in fig. 3.

Referring to fig. 7 in combination, the outboard motor 100 further includes the following structure in addition to the structure shown in fig. 3:

the fixture 20 is fixedly provided with a second rack 22, the second rack 22 and the first rack 12m are arranged in parallel at intervals, and the tooth surface is opposite to the second direction X. The second rack 22 is connected to the transmission mechanism 32, and the second motor 31 can move in opposite directions relative to the second rack 22 and the first rack 12m, respectively. Optionally, the outboard motor 100 further includes an elevating platform 23, the elevating platform 23 is mounted on the fixture 20 and can be elevated along the first direction Z, and the elevating platform 23 is fixedly connected to the second motor 31 and is used for supporting the second motor 31 when the second motor 31 stops operating.

In the case where the transmission mechanism 32 includes the worm wheel 32b and the worm 32a, the worm wheel 32b or a gear coaxially disposed therewith may be disposed between the first rack 12m and the second rack 22, and both sides of the worm wheel 32b are respectively engaged with the first rack 12m and the second rack 22.

In this embodiment, the driving of the second motor 31 can drive the first rack 12m and the second rack 22 to move in opposite directions and in synchronization with each other relative to the worm wheel 32b, that is, the first rack 12m moves at a speed twice as fast as the torque of the worm wheel 32b relative to the second rack 22, so that the external unit body 10 has the effects of increasing the lifting speed and enlarging the stroke.

Fig. 8 shows another exemplary embodiment of the outboard motor 100 in the present embodiment.

Referring to fig. 8, an outboard motor body 10 of an outboard motor 100 of the present embodiment includes a head 11, a first connecting shaft 15, and a second connecting shaft 16. In this embodiment, the structure of the handpiece 11 can be seen from the description of the embodiment shown in fig. 3. The propeller assembly 13 composed of the propeller 13b and the first motor 13a in this embodiment may adopt the embodiment shown in fig. 3 or fig. 4.

The second coupling shaft 16 is connected to the jig 20 and extends in the first direction Z. For example, the second coupling shaft 16 is connected to the clamp 20 by means of bearings, suspensions, brackets, etc. The second connecting shaft 16 has no motion component in the second direction X, i.e. the length direction of the second connecting shaft 16 is always kept in the first direction Z.

In other embodiments, the second coupling shaft 16 may be configured to be rotatably engaged with the clamp 20 along the axis thereof, such that the rotation of the second coupling shaft 16 can swing the first coupling shaft 15 and the propeller assembly 13 connected thereto laterally (i.e., in a direction perpendicular to the first direction Z and the second direction X) to adjust the steering of the ship 300. The first connecting shaft 15 is rotatably connected to the second connecting shaft 16 at one end and is provided with the propeller assembly 13 at the other end, and the first connecting shaft 15 and the propeller assembly 13 form a first part S1.
