[0001] The present invention relates to the technical field of water equipment, in particular to a power floating board. Background Art

[0002] A kickboard is a prop used by swimmers to assist with swimming, snorkeling, and other underwater activities. Most kickboards only provide buoyancy and lack propulsion. Using such boards for underwater activities results in slow speeds and significant functional limitations. Some kickboards incorporate powered propulsion, powered by batteries. These propulsion systems typically use pumps or propellers to generate the propulsion, providing forward momentum for the operator, allowing them to quickly swim through the water.

[0003] The current propeller of the power float includes multiple motors, which not only increases the weight of the power float, thereby reducing the gravity that the power float can withstand, but also increases the cost, reduces the maintenance and installation efficiency, and affects the user experience.

[0060] Example 1

[0061] This embodiment provides a powered floating board that can be used for swimming, snorkeling and other water activities. Figure 1 As shown, the powered float includes a housing, a water pipe disposed within the housing, and a propeller disposed within the water pipe. To use the powered float, the user lies on the float, holds the front end of the float with both hands, and activates the propeller, which drives water out toward the rear of the float, propelling the user forward.

[0062] Specifically, the water flow conduit includes a connected inlet section and an outlet section. The front end of the inlet section communicates with the exterior of the housing, allowing water from outside the housing to enter the water flow conduit. The rear end of the outlet section communicates with the exterior of the housing, allowing water to be ejected from the outlet section after being driven by the propeller. The propeller includes a motor 3 and a propeller 7. The output shaft of the motor 3 is in driving connection with the propeller 7, driving the propeller 7 to rotate, thereby driving the water to be ejected from the outlet section toward the rear side of the power float, thereby driving the power float forward.

[0063] In this embodiment, the front end of the housing is provided with a water inlet screen 6. The front end of the water inlet section is connected to the water inlet screen 6. After passing through the water inlet screen 6, external water enters the water flow pipe, providing safety protection, protecting the user from injury from the rotating propeller 7. It also filters impurities in the water, preventing them from clogging the water flow pipe or the propeller, thereby ensuring the normal operation of the powered float. The rear end of the housing is provided with a water outlet 134. The rear end of the water outlet section is connected to the water outlet 134, so that the water pushed by the propeller is ejected through the water outlet 134.

[0064] In this embodiment, the pusher is only provided with one motor 3, which can reduce the weight of the power float, thereby increasing the gravity that the power float can withstand on the basis of the same buoyancy generated by the power float; a single motor 3 can also reduce the cost of the power float, improve the efficiency of disassembly and assembly, and facilitate maintenance.

[0065] In order to ensure that the power float has sufficient propulsion power, the propeller is arranged in the water inlet section, which can ensure the water flow rate and flow rate entering the water flow pipe from the outside of the shell, thereby ensuring higher propulsion efficiency, so that the power of the motor 3 with the same power can be fully utilized, ensuring the optimization of the efficiency of the propeller, thereby ensuring higher propulsion efficiency.

[0066] When a user uses a power float, the upper body lies on the power float, and the water sprays out backwards and hits the user, which not only affects the user experience, but also increases the resistance of the water spray and affects the forward movement of the power float.

[0067] To address this issue, the water conduit in this embodiment is equipped with two outlet sections, correspondingly with two water spouts 134. The ends of the two outlet sections, connected to the spouts 134, extend away from the central axis of the housing. By extending the outlet sections away from the central axis of the housing, water flowing through the outlet sections is ejected from both sides of the powered float. When using the powered float, the user can position themselves between the two outlet sections, thus avoiding water spraying onto them and improving the user experience.

[0068] In this embodiment, the front ends of the two water outlet sections meet and are connected to the water inlet section, so that the water flow conduit is roughly Y-shaped, which is conducive to simplifying the structure of the water flow conduit.

[0069] In other embodiments, more than two water outlet sections may be provided, and the specific number may be set according to actual needs.

[0070] The propeller is arranged in the water inlet section, so that the two water outlet sections can share one propeller, thereby reducing the number of propellers to achieve the purpose of reducing cost and weight.

[0071] In other embodiments, a propeller 7 may be provided in each water outlet section, and each propeller 7 is connected to the motor 3 in the water inlet section through a transmission assembly, so that multiple propellers 7 are driven to rotate by a single motor 3 .

[0072] In order to make the power float more stable during use, the water inlet section can be located on the central axis of the shell and extend along the central axis. The two water outlet sections are symmetrically arranged relative to the central axis of the shell, so that when the propeller is working, the water flow is more evenly distributed in the water flow pipe, which is conducive to maintaining the stability of the power float and avoiding the deflection of the power float.

[0073] In this embodiment, the water flow conduit includes an upper conduit cover 21 and a lower conduit cover 22 that are interlocked and sealed. The upper conduit cover 21 and the lower conduit cover 22 are interlocked to form the water flow conduit, making it easy to disassemble and assemble the propeller within the water inlet section.

[0074] Optionally, the pipe upper cover 21 and the pipe lower cover 22 can be sealed by a seal, and the edges of the pipe upper cover 21 and the pipe lower cover 22 are provided with fixing lugs. The fixing lugs of the pipe upper cover 21 and the pipe lower cover 22 can be fastened by screws, and the seal is provided on the inner side of the fixing lugs, thereby ensuring the sealing performance of the water flow pipe.

[0075] In other embodiments, the water flow conduit may also be integrally formed, such as by blow molding, which is easy to process and has good sealing performance.

[0076] Optionally, a mounting seat may be provided in the water inlet section, and the propeller may be fastened to the mounting rib by screws to complete the fixation of the propeller.

[0077] In order to further increase the flow rate of the water provided by the propeller to the two water outlet sections of the diversion, the structure of the water flow pipeline is further improved in this embodiment, so that the propeller using a single motor 3 has a higher propulsion efficiency.

[0078] Specifically, in order to facilitate the entry of water into the water flow pipe, the cross-sectional area of ​​the water inlet section can be gradually reduced along the direction of the water flow, so that the opening of the water inlet section expands outward, which is conducive to increasing the flow rate of water entering the water flow pipe; after the cross-sectional area of ​​the water inlet section is gradually reduced, the pressure of the water flow can be increased, which is conducive to increasing the flow rate of the sprayed water.

[0079] Optionally, the cross-sectional area of ​​the water outlet section may gradually decrease along the water flow direction to further increase the pressure of the water flow, which is beneficial to increasing the flow rate of the sprayed water flow.

[0080] In this embodiment, the cross-sectional areas of the water inlet section and the water outlet section gradually decrease along the water flow direction, which is beneficial to avoiding water boundary layer separation and improving water flow efficiency.

[0081] Optionally, the cross section where the water inlet of the water inlet section is located is the normal cross section of the water inlet section, and the cross section where the water outlet of the water outlet section is located is the normal cross section of the water outlet section.

[0082] Optionally, the area of ​​the water inlet of the water inlet section is not less than the sum of the areas of the water outlets of the two water outlet sections, so that the water flow rate entering the water flow pipe from the water inlet is not less than the water flow rate ejected from the water outlet, so as to ensure that the amount of water entering can stably supply the amount of water ejected after acceleration by the propeller.

[0083] In this embodiment, the rear end of the water outlet section is further connected to a nozzle 5. The water flows out through the nozzle 5, which can further increase the water flow speed, thereby increasing the driving force of the water flow on the power float.

[0084] Optionally, the nozzle 5 can be rotatably disposed in the water spout 134. The water flow can form a spiral water flow under the action of the rotation of the nozzle 5, which can further increase the flow rate of the water flow, thereby increasing the driving force of the water flow on the power float.

[0085] Exemplarily, multiple spiral grooves are provided in the nozzle 5. After the water flow in the water outlet section enters the nozzle 5, the water flow flows along the spiral grooves, which can push the nozzle 5 to rotate in the water outlet 134. The nozzle 5 does not require additional power drive, which is conducive to reducing the cost of the power float.

[0086] For example, the power float further includes a rotary drive member connected to the nozzle 5 to drive the nozzle 5 to rotate. The rotary drive member can be a rotary motor that drives the nozzle 5 to rotate. The speed of the nozzle 5 is controllable, thereby better controlling the flow rate of the sprayed water.

[0087] Alternatively, the nozzle 5 may be an elastic tube, such as a bellows. The bellows has a bendable property, and before use, the bellows can be turned to adjust the direction of the nozzle opening of the bellows according to the desired water jetting direction.

[0088] In order to improve the water intake efficiency, the propeller 7 is located on the side of the motor 3 close to the water inlet of the water intake section, so that the water flow can enter the water flow pipe under the drive of the propeller 7.

[0089] The propeller 7 and the motor 3 are both arranged in the water inlet section. The diameter of the motor 3 is smaller than the diameter of the propeller 7. Preferably, the diameter of the motor 3 is less than or equal to two-thirds of the minimum diameter of the water inlet section, or the circular cross-sectional area of ​​the motor 3 is less than or equal to one-half of the minimum cross-sectional area of ​​the water inlet section, so that there is a certain gap between the motor 3 and the water inlet section to allow sufficient water flow to pass through.

[0090] In this embodiment, the powered float further includes a sealing box 4 and an electronic control assembly. The electronic control assembly is housed within the sealing box 4, which is then housed within the outer casing. The provision of the sealing box 4 for housing the electronic control assembly not only isolates the electronic control assembly from the water pipes, but also allows for a separate, sealed assembly, improving the waterproofing of the electrical components. Furthermore, it reduces the waterproofing requirements for the outer casing, making the outer casing easier to manufacture.

[0091] like Figure 2 As shown, sealed box 4 includes a box body 41, a box cover 42, and an encapsulation layer 44. Box body 41 is open at one end to facilitate the installation of the electronic control component. After the electronic control component is installed in box body 41, it is encapsulated with an encapsulating material. The encapsulating material forms encapsulation layer 44. This not only secures the electronic control component within box body 41, but also wraps around the outside of the electronic control component to provide a waterproof effect. Box cover 42 is sealed to box body 41 to close the opening of box body 41 and further prevent water from entering box body 41.

[0092] In this embodiment, the electronic control component can achieve a double-layer sealing effect through the packaging layer 44, the box body 41 and the box cover 42 arranged outside the electronic control component, so that the sealing effect of the electronic control component is better.

[0093] Optionally, a sealing ring 43 is provided between the box body 41 and the box cover 42, and the box body 41 and the box cover 42 are fastened and fixed by screws, so that the fixing effect of the box body 41 and the box cover 42 is good and the sealing is reliable.

[0094] To facilitate the packaging of the electronic control component, a receiving groove is provided within the box body 41. The electronic control component is placed in the receiving groove, and the packaging material is filled into the receiving groove to submerge the electronic control component to complete the packaging of the electronic control component. The provision of the receiving groove allows the electronic control component to be positioned before packaging, preventing the electronic control component from moving during the packaging process, thereby improving the packaging effect.

[0095] Optionally, the height of the top of the receiving groove is smaller than the height of the top of the box body 41 to prevent excessive packaging material from affecting the installation of the box cover 42 and the box body 41. When the packaging material is about to overflow the receiving groove, the supply of packaging material is stopped to avoid excessive packaging material.

[0096] To further ensure the electrical safety of the power float, a water inlet detection module 46 electrically connected to the control component is also provided in the sealing box 4. The water inlet detection module 46 can detect whether water has entered the sealing box 4. When water is detected in the sealing box 4, an alarm signal is sent to the control component so that the control component can cut off the power supply of the power float in time.

[0097] Optionally, the water ingress detection module 46 may include a water sensor that turns on upon contact with water, thereby determining whether water has entered the sealed box 4. It is worth noting that the water sensor is a conventional structure in the art, and its specific structure, connection circuitry, and principles with the control component are all conventional in the art. In this embodiment, any specific structure, connection circuitry, and principles with the control component in the prior art may be employed.

[0098] In this embodiment, the electronic control component includes a control component and a battery. The control component is electrically connected to the propeller and the battery respectively. The control component can control the battery to supply power to the propeller and control the start and stop of the propeller to provide power for the power float.

[0099] To facilitate the installation of components in the housing, such as Figure 1 As shown, the housing includes an upper shell and a lower shell 13 that are fastened together, and an installation space for accommodating the fluid pipeline and the sealing box 4 is formed between the upper shell and the lower shell 13. Optionally, the upper shell and the lower shell 13 can be connected by snap-fitting or fasteners such as screws.

[0100] The electronic control components generate a lot of heat during operation. In order to avoid the electronic control components from overheating and affecting their working stability, such as Figure 3 As shown, a heat dissipation element 45 is further provided on the outside of the box body 41. The heat dissipation element 45 can dissipate the heat generated by the electronic control components in the box body 41 in a timely manner to reduce the temperature of the electronic control components.

[0101] like Figure 3 As shown, in this embodiment, the heat dissipation element 45 is an aluminum plate, which is mounted on the outer wall of the box body 41. The aluminum plate has a high thermal conductivity, which accelerates heat dissipation. Furthermore, because the housing does not require sealing, a clearance must exist between the upper and lower housings 13. During use of the power float, water can enter the housing through this clearance. The water's contact with the aluminum plate further enhances heat dissipation from the electronically controlled components.

[0102] In other embodiments, the heat dissipation element 45 may also be a thermally conductive silicone layer, which has a high thermal conductivity and is conducive to accelerating heat dissipation. The heat dissipation element 45 may also be provided on the box cover 42, or both the box body 41 and the box cover 42 may be provided with heat dissipation elements 45.

[0103] like Figure 4As shown, to drain water from the housing after the powered float is used, preventing corrosion and bacterial growth caused by residual water inside the housing, the housing is also provided with a drain hole 132. This drain hole 132 communicates with the internal chamber of the housing. When the powered float is in use, water can flow into the housing through the drain hole 132, increasing the amount of water in contact with the heat dissipating aluminum plate and improving heat dissipation. When the powered float is not in use, the water in the housing can be drained through the drain hole 132.

[0104] In this embodiment, the water leakage hole 132 is provided on the lower shell 13 so that when the user carries the power float, the water leakage hole 132 is located on the bottom surface of the power float, thereby facilitating the drainage of water in the shell.

[0105] Furthermore, the inner wall of the housing can be provided with protruding ribs to form a guide groove 133. The guide groove 133 can guide the water in the housing to the leakage hole 132, so that the water in the housing can be drained more thoroughly. Optionally, the guide groove 133 can be provided on the inner wall of the upper housing or on the inner wall of the lower housing 13, as long as it can guide the water in the housing to flow along the guide groove 133 and into the leakage hole 132.

[0106] like Figure 5 As shown, in order to facilitate the user to carry the power float, a handle 131 is further provided on the shell, and the user can carry the power float by holding the handle 131, which is convenient for operation. The user can also adjust the angle of the power float by holding the handle 131 to drain the water in the shell.

[0107] In this embodiment, the handle 131 and the leakage hole 132 are arranged at opposite ends of the shell, so that when the user holds the handle 131 to lift the power float, the handle 131 is located at the higher end of the power float, and the leakage hole 132 is located at the bottom end of the power float to facilitate water drainage.

[0108] Optionally, the guide groove 133 may be a stepped structure or have a certain slope, and the leakage hole 132 is connected to the deeper end of the guide groove 133 so that water entering the guide groove 133 flows downward to the leakage hole 132.

[0109] In order to improve the comfort of users when using the powered float, the upper shell includes an upper plate 11 and a support frame 12. The upper plate 11 is made of a soft material, and the support frame 12 is made of a hard material. The upper plate 11 is arranged on the top of the support frame 12, and the support frame 12 is arranged on the lower shell 13. The water pipe and the sealing box 4 are both arranged between the support frame 12 and the lower shell 13. The upper plate 11 is made of a soft material, which can make the upper plate 11 feel better and avoid the material being too hard to affect the user's comfort. The support frame 12 serves as a rigid skeleton (such as a skeleton made of one or more materials such as plastic, carbon fiber, aluminum alloy, etc.), which can support the upper plate 11 and prevent the upper plate 11 from collapsing. At the same time, a storage space is formed between the upper plate 11 and the lower shell 13 for arranging structural components including but not limited to electronic control components, water pipes, etc.

[0110] In this embodiment, the upper plate 11 is made of ethylene vinyl acetate copolymer (EVA) material. EVA material has the advantages of good softness, shock resistance, anti-slip and strong pressure resistance. This material is environmentally friendly and skin-friendly, which can bring users a very good usage experience.

[0111] In other embodiments, the upper plate 11 may also be made of materials such as leather, silicone, polypropylene (PP), polyurethane, and polyethylene foam (EPE).

[0112] Optionally, the upper plate 11 and the support frame 12 can be fixed by bonding or by clamping, which is a simple fixing method with good fixing effect; the support frame 12 and the lower shell 13 can be fixed by clamping and / or by fasteners such as screws.

[0113] like Figure 6 As shown, in this embodiment, the support frame 12 is a thin-walled structure. The bottom of the upper plate 11 is disposed in a mounting groove that engages with the support frame 12, and the support frame 12 is fixedly mounted in the mounting groove. The thin-walled structure of the support frame 12 provides good rigidity for supporting the structure, while also being lightweight, which helps improve the load-bearing capacity of the power float.

[0114] Preferably, the thin-wall structure is attached to the bottom of the upper plate 11 , which can improve the supporting effect on the upper plate 11 .

[0115] Preferably, the middle of the support frame 12 is hollowed out to reduce the weight of the support frame 12, thereby reducing the overall weight and cost of the power float.

[0116] The support frame 12 and the upper plate 11 can also be fixed with auxiliary adhesive to improve the fixing effect of the upper plate 11 and the support frame 12. The support frame 12 is provided with a hook 121, which engages with the hole on the lower shell 13 to fix the support frame 12 to the lower shell 13.

[0117] In this embodiment, a card slot can be further provided on the inner wall of the upper plate 11 , and the card slot can be used to clamp the water pipe and the sealing box 4 to facilitate the fixation of the water pipe and the sealing box 4 .

[0118] In other embodiments, the upper shell can be made of a hard material. To improve user comfort, a protective cover made of a soft material can be placed on the outer side of the upper shell. The protective cover is connected to the upper shell for easy and quick assembly and disassembly, and can be changed to different colors and surface patterns according to user preferences.

[0119] In this embodiment, the power float also includes a control switch electrically connected to the electronic control component through a wire. The control switch includes a power switch and a power switch. The power switch is used to control the start and stop of the propeller, and the power switch is used to control the on and off between the battery and the propeller.

[0120] Specifically, the control switch is arranged at the bottom of the housing to prevent the user from accidentally operating the touch switch, which is beneficial to improving the safety performance of the power float.

[0121] The inner wall of the shell is also provided with a wiring channel, and the wires connecting the various electrical components in the shell can be passed through the wiring channel. On the one hand, it can fix the position of the wires to prevent the wires from being worn due to uncertain position. On the other hand, it can play a waterproof role, thereby ensuring the electrical safety of the power float.

[0122] In this embodiment, the wires passing through the wiring channel include but are not limited to wires connecting the motor 3 and the electronic control component, wires connecting the power switch and the electronic control component, wires connecting the indicator light and the electronic control component, and wires connecting the power switch and the electronic control component.

[0123] In this embodiment, two power switches are provided on the outer shell, and both power switches are electrically connected to the control component in the electronic control component. The control component controls the pusher to start only when both power switches are triggered, so as to further avoid the user from accidentally starting the pusher and improve the safety of the power float.

[0124] The two power switches are respectively arranged on the left and right sides of the bottom of the upper shell. After the user lies on the power float, he / she wraps his / her arms around the power float so that both hands are near the power switches to facilitate triggering the power switches.

[0125] In this embodiment, the control component may include a microcontroller unit (MCU), also known as a single chip microcomputer. Figure 7 and Figure 8The following are circuit diagrams for the left and right power switches, respectively. KEYML and KEYMR are connected to the microcontroller's I / O ports, respectively, to detect the status of the left and right power switches. When the user is not pressing a power switch, the corresponding I / O port is high (3.3V); when the user is pressing a power switch, the corresponding I / O port is low (0V). The microcontroller determines whether the power switch has been triggered by detecting whether the I / O port is low or high.

[0126] To allow the user sufficient time to adjust their posture and stabilize on the powered float after activating the thrusters, the control unit can delay the thrusters from activating for a specified time when both power switches are pressed simultaneously, providing the user with sufficient preparation time. The specific extended time can be set according to actual needs.

[0127] To facilitate other operations while the powered float is in motion, when one of the two power switches is disconnected while the other remains activated, the propeller continues to operate to keep the powered float moving forward. This allows the user to activate the power switch with one arm while performing other operations with the other, making the powered float more flexible to control. When both power switches are disconnected, the control unit stops the propeller to prevent the powered float from separating from the user.

[0128] In some embodiments, when two power switches are pressed simultaneously, the control component controls the propeller to start, and when the user releases any power switch, the control component controls the propeller to stop running to prevent the power float from separating from the user.

[0129] In some embodiments, when the user presses any one of the two power switches, the control component controls the propeller to start; when both power switches are not pressed, the control component controls the propeller to stop running.

[0130] The control process of the power floating plate in this embodiment is as follows:

[0131] When not in use, the power float is not powered on. When the user presses the power switch, the power float is powered on and remains powered on. The indicator light lights up to indicate the current battery charge and status information, waiting to receive instructions. When the left and right power switches are pressed, the level signal of the IO interface is sent to the micro-control unit. After receiving the signal, the micro-control unit controls the propeller to run at maximum power. When the power float is not placed in the water, the motor 3 is in an idling state, running at the maximum no-load speed. During the operation of the power float, when any power switch is released, the propeller will not stop running. Only when both power switches are released will the propeller stop running.

[0132] Press and hold the power button (e.g., 3 seconds) to shut down the Power Float. This de-energizes the Power Float, reducing static power consumption. This also reduces battery life.

[0133] When the power board is connected to a charger, the charger interface triggers the board to power on. The microcontroller detects the charger connection, displays the indicator light indicating charging, and turns on the charge control MOSFET, allowing the power board to begin charging. When the battery voltage is fully charged, the microcontroller turns off the charge control MOSFET, and charging stops.

[0134] Example 2

[0135] Existing motors use an open outer rotor structure to minimize heat dissipation and size. Open outer rotor motors offer advantages such as high torque, compact size, and excellent heat dissipation. However, this structure is prone to seizure in water containing impurities. Furthermore, direct contact between the magnets and water during use can lead to corrosion, shortening the product lifespan.

[0136] Therefore, this embodiment proposes a power float, which improves the structure of the motor 3 in the propeller on the basis of the first embodiment, so that it can not only meet the heat dissipation requirements, but also avoid contact with water and impurities, thereby extending the service life of the motor. Figures 9-12 As shown, the motor 3 includes a motor housing 31, a stator assembly 32, a rotor assembly 33, and a heat dissipation rear cover 34. The heat dissipation rear cover 34 is connected to the motor housing 31 to form a sealed space. The stator assembly 32 and the rotor assembly 33 are installed in the sealed space. The stator assembly 32 is connected to the motor housing 31, and the rotor assembly 33 is disposed within the stator assembly 32. The heat dissipation rear cover 34 and the motor housing 31 form a sealed space to accommodate the stator assembly 32 and the rotor assembly 33. This provides a waterproof seal, prevents the components within the motor 3 from coming into direct contact with water, and thus prevents the motor 3 from being stuck by impurities. It also reduces water corrosion on the components within the motor 3.

[0137] Optionally, the end of the motor housing 31 away from the heat dissipation rear cover 34 is tapered to reduce resistance.

[0138] Optionally, the heat dissipation rear cover 34 is made of aluminum, which provides excellent heat transfer and heat dissipation. The heat dissipation rear cover 34 can also be made of other materials with good thermal conductivity. Optionally, the heat dissipation rear cover 34 is integrally formed to ensure the sealing of the heat dissipation rear cover 34. In this embodiment, the heat dissipation rear cover 34 is made of aluminum alloy, which not only provides excellent heat dissipation but also meets strength requirements.

[0139] like Figure 11 and Figure 12As shown, the heat dissipation back cover 34 includes a back cover body 341 and a heat conducting portion 342 connected to one side of the back cover body 341. The back cover body 341 is sealed and connected to the motor housing 31, thereby realizing the connection between the heat dissipation back cover 34 and the motor housing 31. The heat conducting portion 342 is arranged between the stator assembly 32 and the rotor assembly 33, and abuts against the inner wall of the stator assembly 32, so that the heat generated by the motor 3 can be quickly conducted to the external water through the heat conducting portion 342, thereby improving the reliability of the motor 3. Optionally, the heat conducting portion 342 and the stator assembly 32 have an interference fit, the connection method is simple, and the heat conduction effect is good. The heat conducting portion 342 can also be connected by a connector, which is not specifically limited here. As long as the heat conducting portion 342 abuts against the inner wall of the stator assembly 32, it is convenient to dissipate the heat generated by the stator assembly 32.

[0140] Optionally, the heat conducting portion 342 is a sleeve structure, so that the heat conducting portion 342 and the stator assembly 32 can be in circumferential contact, with a large contact area and good heat conduction effect.

[0141] To quickly dissipate the heat conducted by the heat conducting portion 342 into the water, the heat dissipating rear cover 34 also includes a heat dissipating portion 343, which is disposed on the side of the rear cover body 341 facing away from the interior of the motor housing 31. The provision of the heat dissipating portion 343 increases the area of ​​the heat dissipating rear cover 34 in contact with the water, further accelerating the transfer of heat generated by the motor 3 into the external water.

[0142] Optionally, the heat dissipation portion 343 includes a first heat dissipation portion 3431 and a second heat dissipation portion 3432 coaxially arranged, the second heat dissipation portion 3432 being sleeved outside the first heat dissipation portion 3431, and the second heat dissipation portion 3432 being connected to the circumference of the rear cover body 341. The first heat dissipation portion 3431 and the second heat dissipation portion 3432 both extend along the length of the motor housing 31, so that the heat conducted away from the heat conduction portion 342 can be evenly conducted to the outside of the motor housing 31 through the first heat dissipation portion 3431 and the second heat dissipation portion 3432 along the length of the motor housing 31.

[0143] Optionally, the first heat sink 3431 has a sleeve structure, and its radial cross-section is annular. The rear cover body 341 is provided with a mounting hole 3411, which communicates with the heat conducting portion 342 and the first heat sink 3431, respectively. This facilitates installation of components within the motor 3 and provides improved heat dissipation. The mounting hole 3411 is coaxial with the heat conducting portion 342 and the first heat sink 3431, resulting in a simple structure and facilitating installation of components within the motor 3.

[0144] Multiple lugs 345 are circumferentially arranged around the second heat dissipation portion 3432. Each lug 345 is provided with a fixing hole 451. The rear cover body 341 is connected to the motor housing 31 via fixing members passing through the fixing holes 451. The lugs 345 connect the heat dissipation rear cover 34 to the motor housing 31, simplifying the structure. Furthermore, the lugs 345, located outside the motor housing 31, also serve to dissipate heat, further improving the heat dissipation efficiency of the motor 3. Alternatively, the fixing members may be bolts.

[0145] The inner diameter of the heat conducting portion 342 is smaller than the diameter of the mounting hole 3411, which in turn is smaller than the inner diameter of the first heat dissipation portion 3431. This arrangement facilitates assembly of the motor 3. The inner wall of the mounting hole 3411 in the rear cover body 341 and the end of the first heat dissipation portion 3431 connected to the rear cover body 341 form a stepped structure, facilitating the installation of the first bearing of the rotor assembly 33. A mounting groove 3421 is provided on the inner wall of the end of the heat conducting portion 342 away from the first heat dissipation portion 3431. A second bearing is mounted within this groove, thereby enabling rotation of the rotating shaft 331. The first and second bearings are respectively sleeved onto the rotating shaft 331, enabling rotation of the rotating shaft 331.

[0146] Optionally, a heat dissipation rib may be provided between the first heat dissipation portion 3431 and the second heat dissipation portion 3432 . The heat dissipation rib is connected to the rear cover body 341 , which can further accelerate heat dissipation. The specific shape of the heat dissipation rib is not limited herein.

[0147] like Figure 9 and Figure 10 As shown, the motor 3 further includes a sealing cover 35, one end of which extends into the first heat dissipation portion 3431, and the other end of the sealing cover 35 is in sealed contact with the first heat dissipation portion 3431. The provision of the mounting hole 3411 facilitates installation of components within the motor 3. The provision of the sealing cover 35 can seal the rotating shaft 331 of the motor 3, preventing water from entering the motor 3 through the heat dissipation rear cover 34 and affecting the performance of the motor 3.

[0148] Optionally, the other end of the sealing cover 35 and the first heat dissipation portion 3431 are sealed by a first sealing structure 381 , and the first sealing structure 381 is a static seal.

[0149] Specifically, if Figure 10As shown, the sealing cover 35 includes a sealing cover body 351 and a supporting portion 352 located at one end of the sealing cover body 351. The outer diameter of the sealing cover body 351 is less than or equal to the inner diameter of the first heat dissipation portion 3431. The circumferential dimension of the supporting portion 352 is larger than the outer diameter of the sealing cover body 351. The sealing cover body 351 extends into the first heat dissipation portion 3431. The supporting portion 352 seals and abuts against the end of the first heat dissipation portion 3431 that is not connected to the rear cover body 341. The supporting portion 352 is sealed and connected to the end of the first heat dissipation portion 3431 that is not connected to the rear cover body 341 via a first sealing structure 381.

[0150] like Figure 11 and Figure 12 As shown, a sealing connection portion 344 is further provided on the circumference of one side of the rear cover body 341 where the heat conducting portion 342 is provided. The sealing connection portion 344 is provided in the motor housing 31 and is sealed to the motor housing 31. The provision of the sealing connection portion 344 can form a sealed connection with the motor housing 31, preventing water from entering through the gap between the motor housing 31 and the heat dissipating rear cover 34, which would affect the practical performance of the motor 3.

[0151] Optionally, a groove structure is provided around the sealing connection portion 344. A second sealing structure 382 is provided between the groove structure and the interior of the motor housing 31. The groove structure facilitates the accommodation of the second sealing structure 382. The second sealing structure 382 prevents water from entering through the gap between the motor housing 31 and the heat dissipation rear cover 34, thereby affecting the practical performance of the motor 3. The second sealing structure 382 is a static seal.

[0152] The output end of the rotating shaft 331 of the rotor assembly 33 passes through the motor housing 31 and is sealed with the motor housing 31 by a dynamic seal structure 37. The output end of the rotating shaft 331 passes through the motor housing 31 and is sealed with the motor housing 31 by a dynamic seal structure 37, which can play a sealing role while achieving relative rotation between the stator assembly 32 and the rotor assembly 33.

[0153] Optionally, the dynamic sealing structure 37 is sealed by two oil seals. The dynamic sealing structure 37 can also be sealed by other seals such as a pan seal and a step seal.

[0154] Optionally, the rear cover body 341 is provided with a plurality of threading holes 3412, through which wires 36 connected to the stator assembly 32 are passed. A seal is formed between the wires 36 and the inner walls of the threading holes 3412. The provision of the threading holes 3412 facilitates the passage of the wires 36 connected to the stator assembly 32. The seal between the wires 36 and the inner walls of the threading holes 3412 provides a seal, preventing water from entering the interior of the motor 3 through the gap between the wires 36 and the threading holes 3412 and affecting the performance of the motor 3.

[0155] Optionally, the wire 36 is sealed against the inner wall of the threading hole 3412 by a third sealing structure 383. The third sealing structure 383 is a static seal. Optionally, the third sealing structure 383 can be a sealing ring or a glue-filled sealing method.

[0156] The first sealing structure 381 , the second sealing structure 382 and the third sealing structure 383 may be formed of O-rings, washers, star rings or other structures as long as static sealing can be achieved.

[0157] The motor 3 is sealed by the dynamic sealing structure 37 , the first sealing structure 381 , the second sealing structure 382 , and the third sealing structure 383 , thereby effectively preventing the motor 3 from being loosely sealed and leaking.

[0158] Optionally, sealant is injected between the first heat dissipation portion 3431 , the second heat dissipation portion 3432 , and the rear cover body 341 to further improve the sealing effect.

[0159] The motor 3 forms a sealed space for accommodating the stator assembly 32 and the rotor assembly 33 through the heat dissipation rear cover 34 and the motor housing 31, which plays a waterproof role. The heat conduction part 342 is arranged between the stator assembly 32 and the rotor assembly 33, and abuts against the inner wall of the stator assembly 32, so that the heat generated by the motor 3 can be quickly conducted out of the heat dissipation part 343 through the heat conduction part 342, and conducted to the external water through the heat dissipation part 343, thereby improving the reliability of the motor 3.

[0160] Example 3

[0161] This embodiment provides a power floating plate, which differs from the second embodiment in that the structure of the heat-conducting portion 342 of the heat dissipation rear cover 34 of the motor 3 is different from the structure of the heat-conducting portion 342 in the second embodiment. The structure of the heat-conducting portion 342 in the second embodiment is an integrated sleeve structure, while the heat-conducting portion 342 in this embodiment can be an arc-shaped structure, which is in thermal contact with the stator assembly 32 to perform a heat-conducting function.

[0162] Optionally, the heat conducting portion 342 may include a single arc-shaped structure, or may include multiple arc-shaped structures. When the heat conducting portion 342 includes multiple arc-shaped structures, the multiple arc-shaped structures are spaced apart to form a cylindrical structure. Of course, the heat conducting portion 342 may also have other shapes, as long as it can effectively conduct heat away from the stator assembly 32 and facilitate good heat dissipation.

[0163] In some embodiments, a thermally conductive but non-conductive material may be used to fill the space between the heat conducting portion 342 and the stator assembly 32 to provide heat conduction. Alternatively, the thermally conductive but non-conductive material may be a thermally conductive sealant, which not only conducts heat but is also waterproof, further improving the waterproof performance of the motor 3.

[0164] Example 4

[0165] This embodiment also provides a power floating plate, such as Figure 13 As shown, the propeller adopts the motor 3 of embodiment 2 or embodiment 3, and a propeller 7 is installed on the rotating shaft 331 of the motor 3. By setting the above-mentioned motor 3, the propeller can achieve good heat dissipation performance and extend the service life of the propeller.

[0166] Because the seal between the rotating shaft and rotor of existing motors requires a dynamic seal, the oil seal generates heat during high-speed rotation. Even with contact with water, the heat cannot be dissipated quickly enough. Long-term use can affect the lifespan of the oil seal and reduce sealing performance. To address the heat dissipation issue caused by the dynamic seal, a gap is provided between the dynamic seal structure 37 of the motor 3 and the propeller 7. This increases the contact area between the rotating shaft 331 of the motor 3 and the water, facilitating water flow across the dynamic seal structure 37 and the rotating shaft 331, thereby improving heat dissipation efficiency. The larger gap provided between the dynamic seal structure 37 of the motor 3 and the propeller 7 improves heat dissipation efficiency.

[0167] Optionally, an auxiliary blade 71 is provided on the inner wall of the motor housing 31 of the propeller 7 at one end close to the dynamic sealing structure 37. When the motor 3 rotates, the auxiliary blade 71 enhances the liquid flow in the internal cavity of the propeller 7, helping to dissipate heat between the dynamic sealing structure 37 and the rotating shaft 331 of the motor 3.

[0168] Optionally, the diameter of one end of the rotating shaft 331 of the motor 3 extending out of the motor housing 31 of the motor 3 is smaller than the diameter of the main body of the rotating shaft 331 of the motor 3, which can reduce the resistance of the underwater propeller.

[0169] Optionally, a spiral groove 3311 is provided at one end of the rotating shaft 331 of the motor 3 extending out of the motor housing 31 of the motor 3 , thereby increasing the heat dissipation area of ​​the rotating shaft 331 and facilitating heat dissipation of the oil seal.

[0170] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
