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 water area movable apparatus 300, and the water area movable apparatus 300 may be various water area vehicles such as a commercial ship, a passenger ship, a yacht, a fishing boat, a sailing boat, and a civil ship. Water area movable apparatus 300 includes hull 310 and propulsion 100.

Hull 310 may provide buoyancy such that water area mobile device 300 may float on surface L1 and may carry people or objects. The hull 310 has a hull space Q1 for being able to accommodate people and things or other structures. The specific structure of the hull 310 may be set as desired.

Thruster 100 is mounted to hull 310 for providing a propulsive force to propel water movable apparatus 300 through the water.

In some embodiments, the thruster 100 is primarily powered by electricity, in which case the water movable apparatus 300 further comprises a battery assembly 311 for powering the thruster 100. Battery assembly 311 may include a number of batteries for storing electricity and supplying electricity to propulsion 100. Alternatively, the battery assembly 311 employs a rechargeable secondary battery. The battery assembly 311 may be mounted on the hull 310, for example, in the hull space Q1, or may be mounted at a suitable position of the propeller 100.

Referring to fig. 1, the propeller 100 in the present embodiment includes a frame 10, an electric control assembly 210, a connecting shaft 20, a bottom case 30, a first motor 40, and a propeller 50. The frame 10 is connected to the hull 310, the electronic control assembly 210 is fixedly connected to the frame 10, the connecting shaft 20 extends along a first direction Z (in the state of fig. 1, the first direction Z is the gravity direction), one end of the connecting shaft 20 close to the frame is connected to the electronic control assembly 210 so as to rotate relative to the hull 310 along with the electronic control assembly 210 to realize tilting (specifically, the tilting mode and the structure are described later), the bottom case 30 is connected to one end of the connecting shaft 20 far away from the frame 10, the propulsion paddle 50 is rotatably connected to the bottom case 30, and the first motor 40 is in transmission connection with the propulsion paddle 50. Furthermore, the first motor 40 is electrically connected to the electronic control assembly 210 and can operate under the control of the electronic control assembly 210 to drive the propulsion paddle 50 to rotate to generate the propulsion force.

The battery assembly 311 is electrically connected to the first motor 40, and is used for supplying power to the first motor 40.

When the propeller 100 in the embodiment of the present application is used, the propeller 50 may interact with water under the driving of the first motor 40 to generate a driving force for driving the water area movable device 300 to move when the connecting shaft 20 is not tilted. Moreover, because the connecting shaft 20 is connected to the frame 10 through the electric control assembly 210, when the propeller 100 is used, the thrust reaction force of the water flow on the propulsion paddle 50 is transmitted to the electric control assembly 210 through the first motor 40 and the connecting shaft 20, the electric control assembly 210 transmits the thrust reaction force to the frame 10, and the electric control assembly 210 plays a role in transmitting the thrust reaction force of the propulsion paddle 50 to the frame 10, so that the thrust bearing of the connecting shaft 20 can be omitted, the structural performance requirement of the connecting shaft 20 is reduced, and the manufacturing cost is reduced.

With reference to fig. 1, the electronic control assembly 210 in this embodiment is fixedly connected to the frame 10, and one end of the connecting shaft 20 is connected to the electronic control assembly 210, so as to rotate with the electronic control assembly 210 relative to the frame 10 to realize tilting. For example, the rack 10 is provided with a first supporting member 63, and the electronic control assembly 210 is fixedly connected to the first supporting member 63, so that the rack 10 supports the electronic control assembly 210.

The specific structure of the electronic control assembly 210 can be set as required. For example, in some embodiments, the electronic control assembly 210 includes an electronic control bracket 211 and a control circuit board 212. The electrically controlled bracket 211 is fixedly connected to the first supporting member 63. The control circuit board 212 is fixed to the electric control bracket 211 and electrically connected to the first motor 40 to control the operation of the first motor 40. Optionally, the electronic control assembly 210 further includes an electronic control housing 213, and the electronic control housing 213 is fixedly connected to the electronic control bracket 211. The electronic control bracket 211 and the control circuit board 212 are disposed in the electronic control housing 213.

In this embodiment, the frame 10 includes a first structure portion 11 and a second structure portion 12, the first structure portion 11 extends substantially along the first direction Z, and the second structure portion 12 is connected to an end of the first structure portion 11 away from the bottom casing 30 and extends to a side away from the electric control bracket 211. The first support 63 is fixed at an intersection of the first structure portion 11 and the second structure portion 12.

In this embodiment, the connecting shaft 20 is rotatably connected to the electric control bracket 211, and the rotation axis Z1 is a central axis of the connecting shaft 20 for driving the propelling paddle 50 to turn. One end of the connecting shaft 20 is rotatably connected to the electric control bracket 211, and the other end is fixedly connected to the bottom case 30. When the driving connecting shaft 20 rotates relative to the electric control bracket 211, the connecting shaft 20 drives the bottom shell 30 to rotate relative to the frame 10, so as to realize the steering of the propeller 100.

As a possible embodiment, a steering motor 214 is provided on the electronic control bracket 211, and a steering transmission mechanism 215 is provided to connect the steering motor 214 and the connecting shaft 20. The steering gear 215 transmits the rotation torque of the steering motor 214 to the connecting shaft 20 so that the connecting shaft 20 can rotate relative to the electric control bracket 211. It is understood that the steering transmission mechanism 215 may be a screw-ball transmission mechanism, a worm gear transmission mechanism, a planetary gear transmission mechanism, a gear set transmission mechanism, etc., and the steering transmission mechanism 215 is not limited to the above-mentioned forms, and any transmission mechanism capable of converting the rotation torque of the steering motor 214 into the rotation torque of the connecting shaft 20 is included in the embodiment of the steering transmission mechanism 215 of the present application.

In this embodiment, the propeller 100 further includes a clamp 61 and a tilting driver 62, the clamp 61 is used for being fixed to the hull 310, for example, connected to the tail of the hull 310, and the frame 10 is rotatably connected to the clamp 61 to drive the electronic control bracket 211 to tilt relative to the clamp 61. The rotation axis of the frame 10 rotating the connecting clamp 61 is perpendicular to the axis of the connecting shaft 20. The warping driver 62 is connected between the clamp 61 and the frame 10 in a transmission manner, and is used for pushing the frame 10 to drive the pushing paddle 50 to warp.

The clamp 61 may be fixedly connected to the hull 310 by welding or screwing, or may be integrally disposed with the hull 310.

The frame 10 may be pivotally connected to the clamp 61 by a pivot shaft, pivot pin, or hinge.

The raising driver 62 may be an electric push rod, a hydraulic cylinder, an air cylinder, an electro-hydraulic cylinder, or other devices capable of outputting power. For example, when the lifting driver 62 is an electric push rod, one end of the electric push rod is mounted on the clamp 61, the other end of the electric push rod is a telescopic end, the telescopic end is connected to the frame 10, and the electric push rod can push the frame 10 and the electric control assembly 210 to rotate relative to the clamp 61 through the telescopic end, so that the connecting shaft 20 connected to the electric control assembly 210 and the propulsion paddle 50 connected to the connecting shaft 20 rotate and lift.

In this embodiment, the propeller 100 further includes a connection housing 31. The connection housing 31 surrounds the connection shaft 20 and is connected between the bottom case 30 and the electronic control housing 213. The connecting shell 31 is fixedly connected to the bottom shell 30 and can rotate with the bottom shell 30 relative to the electronic control shell 213. The connection housing may be made of aluminum, and since the connection housing 31 made of aluminum has a light weight and corrosion resistance, the connection housing 31 is fixed to the bottom case 30 to reduce a load weight to the connection shaft 20. It is understood that, in order to further reduce the load weight on the connecting shaft 20, the bottom casing 30 may also be made of an aluminum casing.

It should be noted that, on the premise of no conflict, the various embodiments shown in fig. 6 to fig. 12 can be applied to the structure of the propeller 100 shown in fig. 14, and are not described herein again.

In this embodiment, the thrust of the propulsion paddle 50 is transmitted to the electric control assembly 210 through the first motor 40 and the connecting shaft 20, the electric control assembly 210 transmits the thrust to the frame 10, and the electric control assembly 210 plays a role in transmitting the thrust of the propulsion paddle 50 to the frame 10, so that the thrust can be prevented from being played by the connecting shaft 20, the structural performance requirement of the connecting shaft 20 is reduced, the manufacturing cost is reduced, the connecting shaft 20 can be protected by the connecting shell 31 around the connecting shaft 20, the connecting shell 31 has corrosion resistance, the weight is reduced, and the protective performance is better. And an aluminum structure is adopted to replace a steel part, so that the influence of electrochemical corrosion is reduced.

More specifically, in order to reduce the vibration force of the first motor 40 transmitted by the electronic control assembly 210 to the frame 10, a damping suspension is provided on the first support 63, and the damping suspension on the first support 63 is used to absorb the vibration force, so as to prevent the electronic control bracket 211 from transmitting the vibration force of the first motor 40 to the frame 10, thereby preventing the vibration force of the first motor 40 from being transmitted to the hull 310.

With continued reference to fig. 1, in this embodiment, the bottom case 30 defines an internal space Q2, and the first motor 40 is mounted to the internal space Q2 and thermally coupled to the bottom case 30. Because the first motor 40 is disposed on the bottom casing 30 and thermally coupled to the bottom casing 30, heat generated during the operation of the first motor 40 can be transferred into water through the bottom casing 30, so that the heat dissipation effect is good, and the dependence on an additionally designed heat dissipation system (such as an additionally designed air cooling system, a pump element water pumping cooling system, etc.) can be reduced. In the case that the heat dissipation requirement can be satisfied by the conductive heat dissipation of the bottom case 30, the aforementioned heat dissipation system with additional design can be completely omitted.

Therefore, compared with the prior art that the first motor 40 is disposed on water and a cooling system such as a water cooling system needs to be additionally configured, the propeller 100 in the embodiment of the present application has the advantages of good cooling effect, short cooling path, or capability of simplifying/canceling the additionally designed cooling system, small occupied space of the cooling structure, simple structure, and low cost.

In addition, compared with the prior art, the first motor 40 is arranged in the bottom shell 30, the relative position of the first motor and the propelling paddle 50 is small, the transmission path is short, and the propelling efficiency is high. Moreover, the first motor 40 is located in the inner space Q2 of the bottom shell 30 and is far away from the user on the hull 310, and the noise generated by the first motor 40 has less influence on the user due to the absorption and blockage of the structures such as the bottom shell 30.

In this embodiment, the bottom case 30 may be a shell-shaped structure made of a heat conductive material such as aluminum alloy, and the inner space Q2 surrounded by the shell-shaped structure is used for accommodating the first motor 40. A heat conducting structure 46, such as a heat conducting silicone, may be disposed between the first motor 40 and the bottom housing 30. Thus, when the water area movable device 300 is driven, the bottom case 30 is at least partially immersed in water and is in good contact with water for heat conduction, and heat generated when the first motor 40 operates can be transferred to the bottom case 30 through the heat conduction structure 46 and then transferred to water through the bottom case 30, so that heat dissipation of the first motor 40 is realized.

In this embodiment, the propulsion paddle 50 may be a propeller that is driven to rotate to propel the water movable apparatus 300.

Referring again to fig. 1, in some embodiments, the propeller 100 further includes a water pressing plate 70. The water pressing plate 70 has a substantially plate-like structure perpendicular to the direction of gravity. The water pressing plate 70 is connected to the bottom casing 30, and the water pressing plate 70 and the bottom casing 30 may be integrally cast or may be two separately formed members that are connected together by a screw connection, a welding, or the like.

In this embodiment, the water pressing plate 70 is connected to the lower case 30 at a position closer to the upper side (the side closer to the frame 10), extends to the side away from the hull 310, and is located above the propulsion paddle 50. In this way, the propulsion paddle 50 is located at the side of the water pressing plate 70 far from the frame 10, and the water waves caused by the operation of the propulsion paddle can be controlled under the water pressing plate 70, thereby reducing the wave resistance of the water area movable apparatus 300.

In some embodiments, the pressure water plate 70 and the bottom casing 30 are in thermal conductive connection, i.e., the pressure water plate 70 and the bottom casing 30 transfer heat to each other. For example, the water pressure plate 70 and the bottom casing 30 may be integrally formed by the same heat conductive material (e.g., aluminum alloy), or may be connected by a heat conductive material (e.g., metal with good heat conductivity). Therefore, the heat conducted to the bottom casing 30 can be conducted to the water pressing plate 70 and then to the water quickly, in addition to being conducted to the water directly, which is equivalent to increasing the heat dissipation area. In addition, for the embodiment in which the water pressing plate 70 is located above the propelling paddle 50, under the pushing of the propelling paddle 50, the water flows through the water pressing plate 70 at a relatively high speed, so that the heat on the water pressing plate 70 can be taken away quickly and efficiently, and the heat of the first motor 40 can be conducted to the water body through the bottom shell 30 and the water pressing plate 70 relatively quickly.

In some embodiments, the lower surface of the water pressing plate 70 is provided with a water knife plate 71, and the water knife plate 71 is vertically disposed to improve the turning performance of the water area movable apparatus 300.

It can be understood that the bottom shell 30 and the connecting shaft 20 may be fixedly connected, so that the connecting shaft 20 rotates relative to the frame 10, so that the connecting shaft 20 drives the bottom shell 30 to rotate, and finally, the propelling direction of the propeller 100 is turned. The bottom shell 30 and the connecting shaft 20 may also be rotatably connected, the connecting shaft 20 is relatively fixedly connected to the frame 10 through the electronic control assembly 210, and the bottom shell 30 rotates relative to the frame 10, so that the propulsion direction of the propeller 100 is finally turned.

Referring to fig. 2, in one embodiment, the first motor 40 may be a double-stator single-rotor motor, and includes two stators 41 and one rotor 42, wherein the two stators 41 are arranged side by side and respectively electromagnetically cooperate with the one rotor 42 to jointly drive the rotor 42 to rotate. An output shaft 43 of the first motor 40 is connected to the rotor 42 for outputting torque. The use of two stators 41 to drive one rotor 42 can increase the drive force or maintain a smaller cross-sectional area while ensuring a certain drive force. Compared with two thin and short motors which are connected in parallel, the motor has the advantages of being smaller in length and smaller in occupied size.

Referring to fig. 3, in one embodiment, the first motor 40 is a single stator and single rotor motor, and includes a stator 41 and a rotor 42, and the stator 41 and the rotor 42 correspond to each other and drive the rotor 42 to rotate. The output shaft 43 of the first motor 40 is connected to the rotor 42 for outputting torque. In order to obtain sufficient driving force, the first motor 40 is shorter and thicker than the solution shown in fig. 2.

Referring to fig. 4, in one embodiment, the first motor 40 is a single-stator dual-rotor motor, and includes a stator 41 and two rotors 42, and the stator 41 and the two rotors 42 respectively correspond to each other for driving the two rotors 42 to rotate. An output shaft 43 of the first motor 40 is connected to the rotor 42 for outputting torque. The use of two stators 41 to drive one rotor 42 can increase the drive force or maintain a smaller cross-sectional area while maintaining a certain drive force.

Referring to fig. 5, in one embodiment, the first motor 40 is a dual-stator dual-rotor motor, and includes two stators 41 and two rotors 42, and the two stators 41 and the two rotors 42 correspond to each other for driving the rotors 42 to rotate respectively. The output shaft 43 of the first motor 40 is connected to the rotor 42 for outputting torque. The first motor 40 adopts a manner of matching the two stators 41 and the two rotors 42, so that the driving force can be increased, or a smaller sectional area can be kept on the premise of ensuring a certain driving force.

It is understood that a cross section of the first motor 40 perpendicular to the direction of the output shaft 43 is defined as a cross section. In the embodiment of fig. 2, 4 and 5, the power output shaft of the first motor 40 is coaxial with the power shaft of the propelling paddle 50, the cross section of the first motor 40 is smaller than that of the first motor 40 of the embodiment of fig. 3, and the number of the stators 41 or the number of the rotors 42 is increased in a direction parallel to the power output shaft 43, or the numbers of the stators 41 and the rotors 42 are increased, so that the power of the first motor 40 can be kept and not reduced even increased under the condition of reducing the cross section. Under this structure, the resistance of the first motor 40 to the water facing the propulsion paddle 50 is reduced, and the power is not reduced, even can be increased, and because the way of increasing the length of a single stator and a single rotor is avoided, the requirements of easy production and high manufacturing yield of the first motor 40 are met. Of course, the embodiment of the present application is not limited to the first motor 40 in the embodiment of fig. 2, 4, and 5 being disposed in a configuration in which the power output shaft is coaxial with the propeller 50, that is, the power output shaft of the first motor 40 in the embodiment of fig. 2, 4, and 5 may be the power shaft of the vertical propeller 50, or the power shaft of the parallel propeller 50 but offset from the power shaft of the propeller 50.

It will also be appreciated that in the embodiment of fig. 3, the first motor 40 has a larger cross-section than the first motor 40 of the embodiment of fig. 2, 4, 5, while maintaining the same power in the embodiment of fig. 2, 4, 5, the first motor 40 of the embodiment of fig. 3. In the embodiment of fig. 3, the output shaft 43 of the first motor 40 may be disposed coaxially with the power shaft of the propeller 50, so that the water resistance of the first motor 40 to the propeller 50 is increased compared to the embodiments of fig. 2, 4 and 5. In this structure, although the propulsion efficiency of the propulsion paddle 50 is reduced by the first motor 40, the first motor 40 still satisfies the requirement of being thermally coupled with the bottom casing 30, and the first motor 40 can still achieve good cooling and heat dissipation through the bottom casing 30, so that embodiments in this structure also belong to the embodiments of the present application. Of course, in the embodiment of fig. 3, the first motor 40 is not limited to the above layout mode in which the output shaft 43 is coaxial with the power shaft of the propeller 50, and the output shaft 43 of the first motor 40 may be perpendicular to the power shaft of the propeller 50, or parallel to but offset from the power shaft of the propeller 50, so as to reduce the water resistance of the first motor 40 to the propeller 50 and improve the propulsion efficiency. In the embodiment of the present application, the position of the first motor 40 is not limited to the above-mentioned embodiments, and any configuration that can satisfy the requirement that the first motor 40 is thermally coupled to the bottom casing 30 and the first motor 40 can perform heat exchange with the external water through the bottom casing 30 to dissipate heat belongs to the embodiment of the present application.

In the embodiment of the present application, the configuration in which the stator 41 of the first motor 40 is disposed on the outer periphery of the rotor 42 and the configuration in which the rotor 42 of the first motor 40 is disposed on the outer periphery of the stator 41 do not belong to the embodiments of the present application.

Referring to fig. 6 (see also fig. 1), in some embodiments, the first motor 40 is located on a side of the water pressure plate 70 that is away from the housing 10. At this time, the first motor 40 is substantially located at a portion of the bottom case 30 submerged in water, and can directly conduct generated heat to the water through a portion of the bottom case 30 contacting the water, so that the heat dissipation efficiency is high.

In this embodiment, the first motor 40 may be horizontally disposed (i.e., disposed along the second direction X in the drawing) and coaxially connected to the propelling paddle 50. The front end face P1 of the first motor 40 is attached to the surface of the bottom casing 30 near the propeller 50. The front end surface P1 of the first motor 40 is attached to the bottom case 30, so that the heat of the first motor 40 is conducted to the bottom case 30. Of course, as described above, the heat conducting structure 46 such as heat conducting silicone rubber may be filled between the front end surface P1 of the first motor 40 and the bottom case 30 to improve the heat conducting capability of the two. In this embodiment, the propeller 50 is optionally rotatably engaged with the bottom housing 30, and the output shaft 43 of the first motor 40 is connected to the propeller 50 for driving the propeller 50 to rotate. In this embodiment, the first motor 40 correspondingly propels the paddle 50 in the horizontal direction, and will cause a certain blockage to the paddle 50, and if the first motor 40 in the form of the aforementioned double-stator double-rotor, double-stator single-rotor, or single-stator double-rotor is adopted, the first motor 40 can have a smaller cross-sectional area on the premise of ensuring the required driving force, so as to reduce the blockage of the first motor 40 to the paddle 50, and meet the requirements of easy manufacture of the first motor 40 and high production yield.

In other embodiments, the first motor 40 and the propulsion paddle 50 may be staggered to reduce the blocking of the first motor 40 to the propulsion paddle 50, that is, to reduce the water-facing resistance of the first motor 40 to the propulsion paddle 50 by reducing the blocking area of the first motor 40 to the propulsion paddle 50.

For example, as shown in fig. 7, the first motor 40 is rotated 90 degrees to move its output shaft 43 vertically and in a first direction Z a certain distance to be offset from the propulsion paddle 50 in the first direction Z, and then the transmission mechanism 80 (e.g., bevel gear pair 801) is used to realize the transmission of 90-degree rotation angle. The bevel gear pair 801 includes a first bevel gear 81 and a second bevel gear 82, the first bevel gear 81 is connected to the output shaft 43 of the first motor 40, and the second bevel gear 82 is connected to the propulsion paddle 50. In this way, the power of the output shaft 43 of the first motor 40 can be transmitted to the propeller 50, and the propeller 50 is driven to rotate. The first bevel gear 81 and the second bevel gear 82 can be in equal ratio transmission, and can also be in speed reduction transmission or speed increase transmission.

In this embodiment, the first motor 40 is vertically provided, and the stator 41 and the rotor 42 of the first motor 40 are housed in the internal space Q2. A heat conductive structure 46 is provided between the stator 41 and the rotor 42 and the inner wall of the bottom case 30 to achieve thermal coupling with the bottom case 30. Specifically, the heat conducting structure 46 is heat conducting oil for soaking the first motor 40, that is, both the stator 41 and the rotor 42 are in contact with the heat conducting structure 46. A heat conductive structure 46 is injected into the inner space Q2 defined by the bottom case 30, thereby thermally coupling the first motor 40 with the bottom case 30. On one hand, the heat conducting structure 46 can transfer the heat of the first motor 40 to the bottom case 30, so as to achieve heat dissipation and cooling of the first motor 40; on the other hand, the heat conducting structure 46 has an insulating and lubricating effect, so that the stator 41 and the rotor 42 are ensured to be in an insulating environment, and the stator 41, the rotor 42 and the output shaft 43 are lubricated to reduce the internal rotation resistance of the first motor 40. Optionally, the first motor 40 further includes an oil throwing structure fixed to the output shaft 43, and the oil throwing structure is accommodated in the internal space Q2 and used for throwing the heat conduction oil to the periphery of the first motor 40, and finally, the heat conduction oil uniformly contacts the surface of the first motor 40 and then flows to contact the inner wall of the bottom case 30, so as to achieve uniform heat dissipation of the first motor 40. Of course, in other embodiments, the heat conducting structure 46 may also be a heat conducting silicone rubber disposed between the stator 41 and the bottom casing 30, or a heat conducting cotton disposed between the stator 41 and the bottom casing 30, or a heat conducting metal disposed between the stator 41 and the bottom casing 30.

Referring to fig. 8, the transmission mechanism 80 between the output shaft 43 of the first motor 40 and the propulsion paddle 50 may further include a speed change assembly 802. For example, the speed change assembly 802 is constituted by a speed change gear set, and the speed change assembly 802 includes the first gear 83, the second gear 84, the third gear 85, and the fourth gear 86. The output shaft 43 of the first motor 40 is connected with a first gear 83, the first gear 83 is meshed with a second gear 84, the second gear 84 and a third gear 85, and the third gear 85 is meshed with a fourth gear 86, so that the first gear 83, the second gear 84 and the third gear 85 are fixedly connected with each other to rotate at the same speed, and the propulsion paddle 50 and the fourth gear 86 are fixed with each other to rotate at the same speed. In some embodiments, the speed change assembly is a speed reduction mechanism, and the first motor 40 outputs a reduced speed and an increased torque to the propeller 50.

In this embodiment, the speed changing assembly 802 may be integrally integrated with the first motor 40. That is, the first motor 40 is a reduction motor with a reduction mechanism.

The transmission mechanism 80 (e.g., the speed changing assembly 802 and the bevel gear pair 801) in this embodiment can be integrated in the bottom case 30 to dissipate heat together with the first motor 40, thereby reducing the requirement of an additional heat dissipation structure. The first motor 40, the transmission mechanism 80 and other structures are integrated with the underwater part (including the bottom shell 30), so that the material consumption of the shell can be reduced, and the resource waste is reduced. The integrated arrangement of the first motor 40 and the speed changing assembly 802 can also reduce underwater water resistance. The integration of the propeller 50 and the speed change assembly 802 also reduces the number of bearings required. The speed change assembly 802 is disposed in the underwater portion of the propeller 100, and noise is isolated by water, so that sound is reduced and influence on a user is reduced.

In some embodiments, the first motor 40, the speed change assembly 802, and the propulsion paddle 50 are all disposed coaxially. The portion of the speed change assembly 802 located on the axial direction of the output shaft 43 is defined as a motor shielding portion, and the speed change assembly 802 may partially constitute the motor shielding portion or may entirely constitute the motor shielding portion. The cross sectional area of the motor shielding part of the speed changing component 802 in the direction perpendicular to the output shaft 43 is smaller than the cross sectional area of the first motor 40 in the direction perpendicular to the output shaft 43, so that the water facing blocking surface of the propelling paddle 50 cannot be increased by the speed changing component 802, the shielding of the speed changing component 802 and the first motor 40 to the propelling paddle 50 is small, the propeller 100 is guaranteed to reduce underwater resistance, the thrust of the propelling paddle 50 and the gear axial force of the speed changing component 802 are offset, and the service life of a bearing can be prolonged.

It should be noted that the bevel gear pair 801 and the speed change assembly 802 in the transmission mechanism 80 may be disposed in neither (as shown in fig. 6), only one (as shown in fig. 7 or 8), or two (as shown in fig. 9) connected in series between the first motor 40 and the propeller 50.

In other embodiments, the transmission mechanism 80 may be in other forms, such as belt transmission, chain transmission, etc., which are not described herein.

In the foregoing embodiments, the first motor 40 is located below the water pressing plate 70 (far from the side of the rack 10), and in other embodiments, the first motor 40 may be located partially or entirely above the water pressing plate 70 (near the side of the rack 10).

As shown in fig. 10, the inner space Q2 of the bottom casing 30 includes a first space Q3 and a second space Q4 communicating in the first direction Z, the first space Q3 being located on a side of the water pressing plate 70 away from the rack 10, and the second space Q4 being located on a side of the water pressing plate 70 close to the rack 10. The first motor 40 is entirely accommodated in the second space Q4. At this time, the bottom housing 30 is located below the water pressing plate 70, and the first motor 40 does not need to be accommodated, so that the water-facing resistance of the propulsion paddle 50 can be reduced. In the embodiment of fig. 10, the output shaft 43 of the first motor 40 is perpendicular to the power shaft of the propulsion paddle 50, the first motor 40 is not disposed in the propulsion water flow range of the propulsion paddle 50, the first motor 40 is staggered with the propulsion paddle 50, so that the propulsion water flow of the propulsion paddle 50 is not blocked, the first motor 40 is ensured to be cooled and dissipated through the bottom case 30, meanwhile, the water-facing resistance of the propulsion paddle 50 is reduced, and the propulsion efficiency is improved. Of course, in other embodiments, the first motor 40 may be disposed in the second space Q4 in such a manner that the output shaft 43 is parallel to the power shaft of the propeller 50.

Of course, the first motor 40 may also be only partially accommodated in the second space Q4, that is, one part of the first motor is located in the first space Q3, and the other part of the first motor is located in the second space Q4, and the output shaft 43 of the first motor 40 may be perpendicular to the power shaft of the propeller 50, or may be parallel to the power shaft of the propeller 50.

Fig. 10 shows an embodiment in which the first motor 40 is vertically arranged and is drivingly connected to the propulsion paddle 50 through a bevel gear pair 801. Of course, other arrangements of the transmission mechanism 80 described above are equally applicable to embodiments where the first motor 40 is located entirely or partially on the water pressing plate 70, and are not described in detail herein.

In some embodiments, the propeller 100 also includes a second motor 68. The second motor 68 may be the same or a different type of motor than the first motor 40. The second motor 68 is connected in series with the first motor 40 to propel the paddles 50.

As shown in fig. 11, on the basis of the embodiment shown in fig. 10, a second motor 68 is further provided between the bevel gear pair 801 and the propulsion paddle 50, so that the first motor 40 and the second motor 68 essentially achieve the purpose of powering the propulsion paddle 50 in series. This form increases the total propulsion force and the motor has less effect on the total blocking area of the propulsion paddle 50, especially when the first motor 40 and/or the second motor 68 are in the form of elongate motors (such as the aforementioned double rotor double stator motor).

In other embodiments, the second motor 68 and the first motor 40 may be connected in parallel to the propulsion paddle 50. That is, the output shaft 43 of the first motor 40 and the output shaft 43 of the second motor 68 are connected to the propulsion paddle 50 in parallel to collectively propel the propulsion paddle 50 to rotate.

Of course, the embodiment shown in fig. 6 to 9 may also add the second motor 68 in series or in parallel to the transmission path of the first motor 40 and the propulsion paddle 50 to increase the propulsion force or improve the reliability of the power, which is not described herein.

Referring again to fig. 11, the second motor 68 in the present embodiment may be disposed outside the inner space Q2 of the bottom case 30. In other embodiments, the second motor 68 may be disposed within the inner space Q2 of the bottom housing 30 similar to the first motor 40 and thermally coupled to the bottom housing 30 to dissipate heat.

The heat dissipation of the first motor 40 and/or the second motor 68 in this embodiment may be achieved in other ways than by the aforementioned heat conduction via the heat conducting structure 46 between the motor and the bottom housing 30.

For example, fig. 12 illustrates that the interior space Q2 contains a cooling fluid 67 (e.g., water or cooling oil), and the first motor 40 is at least partially immersed in the cooling fluid 67. In this way, the heat of the first motor 40 can be rapidly transferred to the cooling liquid 67 and further transferred to the outside through the bottom case 30. Meanwhile, the propeller 100 may further include a cooling system 90, the cooling system 90 includes a pump 91 and a conveying pipeline 92, the pump 91 is provided with a liquid inlet K3 and a liquid outlet K4, the liquid inlet K3 is used for pumping into the cooling liquid 67, and the liquid outlet K4 is connected with the conveying pipeline 92 for spraying the pumped cooling liquid 67 to the first motor 40.

For the embodiment shown in fig. 10 or 11 in which the first motor 40 is at least partially located above the water pressing plate 70, referring to fig. 13, the first motor 40 can be cooled by making the water waves at the tail of the ship body 310 flow upward and then sprinkle on the outer surface of the bottom shell 30 at the first motor 40 located above the water pressing plate 70 from top to bottom when the ship body 310 travels. The flow path of the water waves for cooling the first electric machine 40 can be seen as indicated by the dashed arrows in fig. 13. Referring to FIG. 1, the water area movable apparatus 300 of the present application may further include an electronic control assembly 210, the electronic control assembly 210 being electrically connected to the first motor 40 for controlling the operation of the first motor 40. The electronic control unit 210 is a motor control device, and can control the rotation speed, the output power, the output torque, and the like of the first motor 40. The specific control circuit and control method may adopt the existing scheme, which is not described herein.

In the case where the second motor 68 is provided, the electronic control unit 210 may also be used to control the operation of the second motor 68.

The first motor 40 in this embodiment may be disposed at an upper position, that is, at a portion of the propeller 100 exposed to the water surface, in addition to being disposed at a lower position (below the water pressing plate 70) or a middle position (near the water pressing plate 70) in the inner space Q2 of the bottom case 30 as described above.

For example, in another embodiment shown in fig. 14, the connecting shaft 20 is provided with a shaft hole K1 extending along the first direction Z, the first motor 40 is connected to one end of the connecting shaft 20 close to the frame 10, and the output shaft 43 of the first motor 40 passes through the shaft hole K1 and then is in transmission connection with the propulsion paddle 50 through a transmission mechanism 80. The transmission mechanism 80 may include the bevel gear pair 801 and/or the speed changing assembly 802, or other transmission mechanisms, which are not described herein. In this embodiment, the first motor 40 is disposed on the top, and is closer to the electronic control assembly 210, which is beneficial to shortening the electrical connection wires of the two.

The specific structure of the first support 63 in this embodiment may be set as desired. For example, referring to fig. 15, the first support 63 is provided with a first damping sleeve 631, and an axis of the first damping sleeve 631 is perpendicular to the connection shaft 20 and perpendicular to the second direction X. First shock attenuation sleeve 631 wears to be equipped with first shock attenuation axle 633, first shock attenuation axle 633 and first shock attenuation sleeve 631 elastic fit to realize setting up first shock attenuation suspension 651 between electrical control component 210 and the first support piece 63. The electronic control bracket of the electronic control assembly is mounted on the first damping shaft 633 so that the electronic control assembly is fixed to the frame by the first support. The first shock absorbing suspension 651 absorbs the vibration of the electronic control assembly 210, so as to prevent or reduce the vibration transmitted by the electronic control assembly 210 or the first motor 40 to the rack 10, and the first support 63 applies a pulling force in the first direction Z to the electronic control assembly 210, so as to reduce the non-axial swing of the connecting shaft 20. The connecting shaft 20 may be of a steel structure having high strength, so that the connecting shaft 20 has structural reliability.

It is understood that the connection manner of the connection shaft 20 and the bottom case 30 in the embodiment of the present application is not limited to the above-described embodiment.

In another possible embodiment, referring to fig. 16, the connecting shaft 20 may be rotatably connected to the bottom shell 30 (e.g., by a bearing 32), and the connecting shaft 20 is fixed to the electronic control assembly 210. The pusher 100 may further include a host bracket 33 fixed with the bottom case 30. The host bracket 33 and the bottom case 30 may be integrated or fixed via screws. The propeller 100 further comprises a steering driving mechanism 34, wherein the steering driving mechanism 34 is fixed on the main frame support 33, and applies a rotating torque to the connecting shaft 20 to rotate the bottom shell 30 and the main frame support 33 relative to the connecting shaft 20, so that the propeller 100 can steer. In the case where the connection housing 31 is provided, the aforementioned host bracket 33 and the steering drive mechanism 34 may be provided inside the connection housing 31.

In view of the above description, in the water area movable apparatus 300 and the propeller 100 thereof in the embodiment of the present application, because the connecting shaft 20 is connected to the frame 10 through the electric control assembly 210, when the propeller 100 is used, the reaction force of the water flow on the propeller 50 is transmitted to the electric control assembly 210 through the first motor 40 and the connecting shaft 20, the electric control assembly 210 transmits the reaction force to the frame 10, and the electric control assembly 210 plays a role in transmitting the reaction force of the propeller 50 to the frame 10, so that the thrust bearing of the connecting shaft 20 can be omitted, the structural performance requirement of the connecting shaft 20 is reduced, and the manufacturing cost is reduced.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the present application.
