[0002] In the ship's propulsion system, the engine will generate a lot of heat during operation. If the engine continues to work at high temperature, it will affect the performance and service life of the ship's engine. Therefore, a cooling system is needed to dissipate the heat from the engine. At present, ships generally use natural air cooling or water cooling to dissipate heat from the engine. These two methods require the heat source inside the engine to be transferred to the outside through layers of materials and then carried away by wind or water. There is a temperature gradient, so the cooling efficiency of these methods is low; and the heat source inside the engine cannot be directly cooled, which easily leads to temperature accumulation, forming local hot spots, and affecting the service life of the motor. Summary of the invention

[0103] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0104] like Figure 1As shown, an embodiment of the present application provides a propulsion device 1. The propulsion device 1 includes a water-avoiding portion 11, a motor 12, a wading portion 13 and a transmission component 14. The water-avoiding portion 11 is provided with a working chamber 110; the motor 12 is accommodated in the working chamber 110, and is used to output a rotational torque that can form a propulsion power. The wading portion 13 is fixedly connected to the water-avoiding portion 11, and the wading portion 13 is provided with a liquid storage chamber 130, and a reflux channel 131 connecting the liquid storage chamber 130 and the working chamber 110. The liquid storage chamber 130 is provided with a coolant, and the coolant can exchange heat with the external water environment through the wading portion 13. The transmission component 14 is connected to the water-avoiding portion 11 and the wading portion 13, and is used to transport part of the coolant in the liquid storage chamber 130 to the working chamber 110, and guide the coolant to flow back to the liquid storage chamber 130 through the reflux channel 131 after contacting the motor 12.

[0105] In this way, the coolant can directly contact the motor 12 in the propulsion device 1, so that the motor 12 can be directly thermally coupled with the coolant, reducing the negative impact of the "temperature gradient" on the heat dissipation efficiency of the motor 12, and greatly improving the heat dissipation efficiency. At the same time, the coolant that has been thermally coupled with the motor 12 is transferred to the wading part 13, and the temperature of the coolant can be reduced by thermally coupling the wading part 13 with the external water environment; the cooled coolant can also be pumped to the working chamber 110 again through the transmission component 14 to cool the motor 12, making the entire cooling cycle process fast and efficient.

[0106] In this embodiment, the water-avoiding portion 11 may be a working portion of the propulsion device 1 that is designed not to be immersed in water in the working state, and the water-avoiding portion 11 may specifically be the engine room portion of the motor 12 of the propulsion device 1; the working chamber 110 is used to accommodate the motor 12, and the shell of the water-avoiding portion 11 provides protection for the motor 12 so that the motor 12 does not directly contact the external water environment. The wading portion 13 may be a working portion of the propulsion device 1 that is designed to be immersed in water in the working state, and the wading portion 13 may specifically be the engine room portion of the propeller 124 of the propulsion device 1; the liquid storage chamber 130 is used to accommodate the coolant.

[0107] In this embodiment, the coolant can be a liquid with thermal coupling capability, specifically cooling oil or lubricating oil, or a combination of cooling oil and lubricating oil. The coolant exchanges heat with the external water environment through the wading portion 13. The transmission component 14 can be a connecting portion between the water-avoiding portion 11 and the wading portion 13, specifically, it can be a pipeline connecting the working chamber 110 and the liquid storage chamber 130 respectively; a driving pump 142 can be provided on the pipeline of the transmission component 14, which is used to pump the coolant from the liquid storage chamber 130 to the working chamber 110.

[0108] The propulsion device 1 of the embodiment of the present application is illustrated by an outboard motor applied to a fishing boat or a speedboat. Of course, in other embodiments, the propulsion device 1 may also be a pod propulsion device applied to a sailboat.

[0109] When the propulsion device 1 is in working condition, the water-avoiding portion 11 is located above the water surface, and the water-wading portion 13 is immersed in the water. A driving force for the fluid is generated in the transmission component 14, and the cooling liquid in a low place is continuously pumped to a high place ("low place" and "high place" are relative terms. Compared with the "high place", the "low place" is closer to the side of the water-wading portion 13 away from the water-avoiding portion 11. The movement of the cooling liquid from the "low place" to the "high place" needs to be driven by an external force, and the movement of the cooling liquid from the "high place" to the "low place" can be achieved under gravity). That is, the transmission component 14 pumps the cooling liquid in the liquid storage chamber 130 of the water-wading portion 13 to the working chamber 110 of the water-avoiding portion 11.

[0110] The coolant is transported to the working chamber 110 under the drive of the transmission component 14. The coolant is in direct contact with the motor 12 in the working chamber 110 and is thermally coupled. The motor 12 in the working state generates a large amount of heat during the working process, so that the temperature of the motor 12 is higher than the temperature of the coolant pumped into the working chamber 110 by the transmission component 14. The motor 12 is in direct contact with the coolant, and the heat of the motor 12 is spontaneously transferred to the coolant. The heat of the motor 12 is absorbed by the coolant, which reduces the temperature of the motor 12. The coolant absorbs the heat transferred from the motor 12, which increases the temperature of the coolant. The coolant with increased temperature breaks away from the motor 12 under the action of gravity and falls back into the liquid storage chamber 130. At the same time, the transmission component 14 continues to pump the cooled coolant in the liquid storage chamber 130 to the working chamber 110 and contacts the motor 12, so as to contact and cool the motor 12. The coolant flows back to the liquid storage chamber 130 through the reflux channel 131, and the coolant contacts and thermally couples with the water-wading portion 13. The temperature of the coolant that absorbs the heat of the motor 12 is usually higher than the temperature of the water-wading portion 13 that is in direct contact with the external water environment. The heat of the coolant is spontaneously transferred to the water-wading portion 13, and is transferred to the external water environment through the water-wading portion 13, thereby reducing the temperature of the coolant. The coolant in the liquid storage chamber 130 with a lowered temperature is pumped to the working chamber 110 by the transmission component 14 again, contacts and thermally couples with the motor 12, and continuously cools the motor 12.

[0111] Further integration Figure 2 As shown, the transmission assembly 14 includes a supply pipe 140 and a driving pump 142. The supply pipe 140 is provided with a liquid supply channel 141, and the liquid supply channel 141 is connected to the liquid storage chamber 130 and the working chamber 110. The driving pump 142 is connected to the supply pipe 140 and is used to pump the cooling liquid from the liquid storage chamber 130 to the working chamber 110 through the liquid supply channel 141.

[0112] It can be understood that the supply pipe 140 can be a hard pipe or a flexible pipe or a composite supply pipe in which a hard pipe and a flexible pipe are combined, and a through liquid supply channel 141 is formed inside the supply pipe 140. In this embodiment, the supply pipe 140 is a flexible pipe as an example for demonstration, and the flexible supply pipe 140 is respectively connected to the water-avoiding part 11 and the water-wading part 13, so that the through liquid supply channel 141 is connected to the working chamber 110 and the liquid storage chamber 130, so that the coolant can be pumped from the liquid storage chamber 130 to the working chamber 110 through the supply pipe 140.

[0113] It can be understood that the driving pump 142 is used to drive the liquid in the supply pipe 140 to flow, so as to achieve the purpose of pumping the cooling liquid. The driving pump 142 generally includes a pump body 144 and a driving part 143. The pump body 144 is directly connected to the infusion pipe 150, and the driving part 143 is arranged inside the pump body 144 or connected to the liquid flow channel inside the pump body 144. The driving part 143 can be a mechanical pump or an electronic pump. The driving part 143 pumps the cooling liquid from one end of the pump body 144 to the other end of the pump body 144. In this embodiment, the pump body 144 includes a liquid inlet pump port 145 and a liquid outlet pump port 146, and the liquid inlet pump port 145 and the liquid outlet pump port 146 are both connected to the supply pipe 140; or it can be understood that the pump body 144 is embedded in the supply pipe 140, so that the liquid inlet pump port 145 and the liquid outlet pump port 146 are respectively connected to the liquid supply channel 141 at both ends of the pump body 144, so that the liquid in the supply pipe 140 enters the pump body 144 from the liquid inlet pump port 145 under the drive of the driving unit and is discharged from the pump body 144 from the liquid outlet pump port 146, thereby realizing the transportation of the cooling liquid.

[0114] It is understandable that the driving pump 142 may be a pump structure with an independent driving part (e.g., an electronic pump), which is convenient for independently controlling the driving pump 142, so that the flow of the coolant can be flexibly controlled. The driving pump 142 may also be a mechanical pump connected to the motor 12, and the motor 12 drives the driving pump 142 to operate to improve the energy utilization rate of the propulsion device 1.

[0115] The supply pipe 140 is arranged outside the motor 12 , one end of the supply pipe 140 is connected to the water-wading part 13 through a sealing plug, and the other end is connected to the water-avoiding part 11 through a sealing plug, so that the liquid supply channel 141 is sealed and connected to the inside of the working chamber 110 .

[0116] Further integration Figure 2As shown, in one embodiment, the supply pipe 140 has a liquid inlet end 147 and a liquid outlet end 148, the liquid inlet end 147 is connected to the wading portion 13, the liquid supply channel 141 is connected to the liquid storage chamber 130 via the liquid inlet end 147, and the liquid outlet end 148 extends into the working chamber 110, and the coolant flowing out of the liquid outlet end 148 can fall onto the motor 12. The liquid outlet end 148 extends to the side of the water-avoiding portion 11 away from the wading portion 13, and the coolant can fall onto the motor 12 at the liquid outlet end 148 under the action of gravity.

[0117] In this embodiment, the supply pipe 140 has a liquid inlet end 147 and a liquid outlet end 148 which are arranged at intervals. The liquid inlet end 147 is connected to the water-wading portion 13, and the liquid outlet end 148 extends to the working chamber 110. The liquid supply channel 141 of the supply pipe 140 is in communication with the working chamber 110 and the liquid storage chamber 130. One end of the supply pipe 140 provided with the liquid inlet end 147 extends to the water-wading portion 13 away from the water-avoiding portion 11 for extracting the cooling liquid, and one end of the supply pipe 140 provided with the liquid outlet end 148 extends to the water-avoiding portion 11 away from the water-wading portion 13. The liquid outlet end 148 is located on the side of the motor 12 away from the water-wading portion 13, and is used to allow the cooling liquid to fall to the motor 12 under the action of gravity. When the propulsion device 1 is in a working state, the liquid outlet 148 is located on the side of the driving pump 142 away from the liquid inlet 147 . The driving pump 142 drives the coolant in the liquid storage chamber 130 to enter the liquid supply channel 141 from the liquid inlet 147 , and flows out from the liquid outlet 148 and falls onto the motor 12 .

[0118] Further integration Figure 3 As shown, the transmission component 14 further includes a spray head unit 151 , which is disposed at the liquid outlet 148 and is used to diffuse and spray the coolant output from the liquid outlet 148 to the motor 12 .

[0119] In one embodiment, the liquid outlet 148 extends into the working chamber 110, and a plurality of nozzle units 151 are disposed at the liquid outlet 148 and are connected to the liquid supply channel 141 and are located in the working chamber 110. The nozzle of the nozzle unit 151 is disposed toward the motor 12, and the coolant reaches the nozzle unit 151 through the supply pipe 140, and is diffused and sprayed onto the surface of the motor 12 through the nozzle unit 151. Specifically, the coolant is diffusely sprayed by the nozzle unit 151 to the surface of the motor 12 facing the nozzle unit 151, and the coolant flows toward the side of the motor 12 away from the nozzle unit 151 under the action of gravity. During the flow, the coolant can penetrate into the interior of the motor 12 and between the units (for example, between the stator 121 and the rotor 122, and between the rotor 122 and the first rotating shaft 123) through the gaps between the units in the motor 12, and contact the stator 121, the rotor 122 and the first rotating shaft 123 of the motor 12 to be cooled; the coolant can gather on the side of the motor 12 away from the nozzle unit 151 until the gravity exerted on the gathered coolant is greater than the surface tension between the coolant and the motor 12, so that the coolant continues to fall under the action of gravity, and finally the coolant flows back to the liquid storage chamber 130.

[0120] In this embodiment, the liquid outlet 148 may be in a bent structure in the area above the motor 12, and the liquid outlet 148 is divided into a plurality of sub-segments 149, and the plurality of sub-segments 149 are sequentially arranged end to end, so that the plurality of sub-segments 149 are correspondingly arranged above the motor 12. A plurality of nozzle units 151 may be arranged on each sub-segment 149, and the plurality of nozzle units 151 are all arranged toward the motor 12. The plurality of nozzle units 151 can make the coolant spray more evenly to various parts of the motor 12, thereby improving the efficiency of thermal coupling between the coolant and the motor 12. Of course, in other embodiments, the liquid outlet 148 is connected to the inner wall of the working chamber 110, and is connected to the liquid guide member in the working chamber 110, and the nozzle unit is arranged in the liquid guide member in the working chamber 110.

[0121] Further integration Figure 2 As shown, the transmission component 14 further includes a filter 152 , which is disposed on the supply pipe 140 and is used to filter the coolant passing through the supply pipe 140 .

[0122] In this embodiment, the filter 152 includes a first filter unit 153 and a second filter unit 154. The first filter unit 153 is arranged between the driving pump 142 and the liquid inlet end 147, and the second filter unit 154 is arranged between the driver 161 and the liquid outlet end 148. The first filter unit 153 can be a filter structure for coarse filtering of the coolant, and the second filter unit 154 can be a filter structure for fine filtering of the coolant. The first filter unit 153 can be a filter structure including multiple layers of graphene sheets and filter paper. The "coarse filtering" can be understood as that the first filter unit 153 can filter the impurities with larger particles (such as metal debris, impurity particles) in the coolant; the second filter unit 154 can be a filter structure including filtering materials such as ion exchange resin and composite graphene, and the "fine filtering" can be understood as that the second filter unit 154 can filter the tiny particles in the coolant or the impurity particles dissolved in the coolant, as well as the impurity particles generated in the driving pump 142. In other embodiments, the first filter unit 153 and the second filter unit 154 may be disposed at the downstream of the driving pump 142 , and the second filter unit 154 is disposed downstream of the first filter unit 153 .

[0123] Further integration Figure 2 As shown, the wading portion 13 is provided with a first shell 132 , and the liquid storage chamber 130 is provided in the first shell 132 . The coolant exchanges heat with the external water environment via the first shell 132 .

[0124] In one embodiment, the first shell 132 may be a hard protective shell. The first shell 132 may be made of a light, strong, corrosion-resistant material with high thermal conductivity, such as aluminum alloy.

[0125] It can be understood that the temperature of the coolant after thermal coupling with the motor 12 is usually higher than the temperature of the first shell 132. The coolant falls back into the liquid storage chamber 130 enclosed by the first shell 132 under the action of gravity, so that the coolant in the liquid storage chamber 130 directly contacts and thermally couples with the first shell 132, and the heat of the coolant is transferred to the first shell 132, so that the temperature of the coolant is reduced and the temperature of the first shell 132 is increased. The temperature of the first shell 132 increases, so that the temperature of the first shell 132 is higher than the temperature of the external water environment, the first shell 132 is thermally coupled with the external water environment, and the heat of the first shell 132 is spontaneously conducted to the external water environment, so that the temperature of the first shell 132 is reduced.

[0126] In one embodiment, the water-wading portion 13 is provided with a heat dissipation unit 133, and the heat dissipation unit 133 is arranged inside the liquid storage chamber 130. The heat dissipation unit 133 is connected to the first shell 132 and is extended in a raised manner. The heat dissipation unit 133 is thermally coupled to the first shell 132, and the heat dissipation unit 133 is used to increase the contact area between the coolant and the water-wading portion 13, thereby improving the efficiency of heat exchange between the coolant and the external water environment. In this embodiment, the heat dissipation unit 133 is arranged in the liquid storage chamber 130, and the heat dissipation unit 133 is connected to the bottom end of the water-wading portion 13 away from the water-avoiding portion 11, and the heat dissipation unit 133 is convexly arranged toward the side close to the water-avoiding portion 11. It can be understood that the heat dissipation unit 133 is arranged at the lowest point in the liquid storage chamber 130, so that the coolant in the liquid storage chamber 130 will inevitably contact the heat dissipation unit 133.

[0127] It can be understood that the amount of coolant in the liquid storage chamber 130 can make the coolant submerge the heat dissipation unit 133, so that the heat dissipation unit 133 is immersed in the coolant, and the fluid medium of the coolant contacts and thermally couples with the surface of the heat dissipation unit 133. The temperature of the coolant after thermal coupling with the motor 12 is usually higher than the temperature of the heat dissipation unit 133. The coolant is thermally coupled with the heat dissipation unit 133, and the heat of the coolant is transferred to the heat dissipation unit 133, so that the temperature of the coolant is reduced, and the temperature of the heat dissipation unit 133 is increased. The heat dissipation unit 133 is directly connected to the first shell 132, and the heat of the heat dissipation unit 133 is transferred to the first shell 132 via the connection between the heat dissipation unit 133 and the first shell 132. The first shell 132 undergoes thermal interaction with the external water environment to complete heat dissipation. The heat dissipation unit 133 can increase the actual contact area between the first shell 132 and the coolant, thereby improving the efficiency of thermal interaction between the coolant and the first shell 132.

[0128] In one embodiment, the heat dissipation unit 133 includes a plurality of heat dissipation fins 134 , and the plurality of heat dissipation fins 134 are arranged at intervals.

[0129] It can be understood that the multiple heat sinks 134 of the heat sink unit 133 are arranged at intervals and dispersedly. On the one hand, the multiple heat sinks 134 arranged at intervals and dispersedly can have a larger specific surface area than the integrated heat sink unit 133, and can increase the contact area between the coolant and the heat sink unit 133 to improve the heat dissipation efficiency. The multiple heat sinks 134 can be in the form of sheets, and the heat sink 134 can also have other structures that increase the specific surface area, such as annular grooves, blind holes, through holes, etc.

[0130] Further integration Figure 4 As shown, in one embodiment, the wading portion 13 is provided with a drainage unit 135, and the drainage unit 135 is arranged inside the liquid storage chamber 130. The drainage unit 135 is at least arranged on the circulation path of the coolant in the liquid storage chamber 130. The drainage unit 135 is used to prevent the coolant entering the liquid storage chamber 130 from the reflux channel 131 from being directly drawn out of the liquid storage chamber 130 by the transmission component 14.

[0131] It can be understood that, in the working state, the reflux channel 131 and the liquid inlet end 147 are spaced apart on the wading part 13, and the drainage unit 135 can be a plate-like blocking structure arranged between the reflux channel 131 and the liquid inlet end 147. The drainage unit 135 is provided with a reflux hole 136 for the coolant to pass through, and the reflux hole 136 is arranged corresponding to the location of the heat dissipation unit 133; the coolant returns to the liquid storage chamber 130 through the reflux channel 131, passes through the heat dissipation unit 133 and is cooled, and then returns to the liquid inlet end 147 under the driving force of the transmission component 14 and is drawn away by the transmission component 14. By providing the drainage unit 135, the distance that the coolant flows from the reflux channel 131 to the liquid inlet end 147 is extended, thereby increasing the cooling time of the coolant, so that the temperature of the coolant reaching the liquid inlet end 147 is as low as possible, thereby making the temperature of the coolant extracted by the transmission component 14 as low as possible, making the temperature difference between the coolant and the motor 12 as large as possible, and increasing the heat exchange efficiency between the coolant and the motor 12, thereby improving the heat dissipation efficiency.

[0132] Further integration Figure 2 As shown, the water avoiding portion 11 is provided with a second shell 111 , the working chamber 110 is provided in the second shell 111 , and the supply pipe 140 is connected to a side of the second shell 111 away from the water wading portion 13 .

[0133] In one embodiment, an end of the water avoiding portion 11 abutting against the water wading portion 13 is provided with an opening 112 communicating with the working chamber 110 , and the reflux channel 131 is communicated with the opening 112 .

[0134] In this embodiment, the water-avoiding portion 11 is in contact with the water-wading portion 13, and at least one opening 112 is provided on the water-avoiding portion 11, and the opening 112 is connected to the reflux channel 131, so that the coolant can smoothly reflux from the working chamber 110 to the liquid storage chamber 130. Furthermore, the size of the opening 112 can be greater than or equal to the inner diameter of the reflux channel 131, so that the coolant can flow from the working chamber 110 to the liquid storage chamber 130 more quickly.

[0135] Further integration Figure 2 As shown, the motor 12 includes a stator 121, a rotor 122 and a first rotating shaft 123. The stator 121 and the rotor 122 are in direct contact with the coolant output from the transmission component 14 to perform heat exchange, the stator 121 is fixed to the water-shielding portion 11, the rotor 122 cooperates with the stator 121 to drive the first rotating shaft 123 to rotate, and the rotor 122 is fixedly connected to the first rotating shaft 123; the stator 121 and the rotor 122 are accommodated in the working chamber 110 in the second housing 111, and the first rotating shaft 123 passes through the second housing 111 and the first housing 132, and extends from the working chamber 110 to the liquid storage chamber 130.

[0136] Furthermore, the stator 121 is a fixed part of the motor 12, and a pair of stationary main magnetic poles with DC excitation are installed on the stator 121; the rotor 122 is a rotating part of the motor 12, and an armature winding is installed on the rotor 122. When the rotor 122 is energized, an induced electromotive force is generated to act as a rotating magnetic field, and then an electromagnetic torque is generated for energy conversion, so that the rotor 122 can rotate relative to the stator 121; the first rotating shaft 123 is connected to the rotor 122, and is used to output the rotation torque generated by the stator 121 and the rotor 122. In this embodiment, the stator 121 surrounds the outer side of the rotor 122, and the first rotating shaft 123 is connected to the rotor 122 and is vertically arranged. It can be understood that the coolant can flow into the stator 121 and the rotor 122 through the gaps between the stator 121 and the rotor 122. For example, the coolant can infiltrate the outer surfaces of the stator 121 and the rotor 122, and the coolant can also infiltrate between the main magnetic poles and the wires of the armature winding to cool the stator 121 and the rotor 122. At the same time, the coolant can also penetrate into the surface of the first rotating shaft 123 blocked by the stator 121 and the rotor 122 along the gap between the first rotating shaft 123 and the stator 121 and the rotor 122, and further fall along the surface of the first rotating shaft 123.

[0137] In one embodiment, the propulsion device 1 further includes a propeller 124 and a propulsion transmission mechanism 125 which are transmission-connected. The first rotating shaft 123 is connected to the propulsion transmission mechanism 125 for transmitting the rotational torque generated by the motor 12 to the propeller 124 .

[0138] Furthermore, the first rotating shaft 123 and the propeller 124 are arranged non-coaxially, and the propulsion transmission mechanism 125 is arranged between the first rotating shaft 123 and the propeller 124 and is in transmission connection with the first rotating shaft 123 and the propeller 124. The stator 121 cooperates with the rotor 122 to generate a rotation torque, the first rotating shaft 123 transmits the rotation torque to the propulsion transmission mechanism 125, and the propulsion transmission mechanism 125 transmits the rotation torque to the propeller 124. The propeller 124 rotates and moves relative to the water through the blades and generates thrust to push the propulsion device 1 forward.

[0139] In one embodiment, the propeller 124 is disposed outside the wading portion 13, and the propulsion transmission mechanism 125 includes a second rotating shaft 126, which passes through the first housing 132 and extends from the inside of the liquid storage chamber 130 to the outside of the liquid storage chamber 130, and the second rotating shaft 126 is transmission-connected to the first rotating shaft 123, and the second rotating shaft 126 is also transmission-connected to the propeller 124. In this embodiment, the second rotating shaft 126 is also disposed through the drainage unit 135, and the second rotating shaft 126 is spaced apart from the heat dissipation unit 133.

[0140] By arranging the first rotating shaft 123 and the propeller 124 non-coaxially, the propeller 124 is connected to the first rotating shaft 123 through the second rotating shaft 126, and the propeller 124 and the second rotating shaft 126 are arranged to be substantially the same as the forward direction of the propulsion device 1, so that the motor 12 and the wading part 13 are staggered, and the volume of the wading part 13 can be reduced, so that the water-facing surface 138 of the wading part 13 can be arranged to be streamlined, thereby reducing the propulsion resistance of the wading part 13 and improving the propulsion efficiency.

[0141] Furthermore, the propeller 124 is arranged outside the wading portion 13 for generating force interaction with the external water environment, the end of the second rotating shaft 126 located outside the wading portion 13 is connected to the propeller 124, and the end of the second rotating shaft 126 located inside the wading portion 13 is transmission connected to the first rotating shaft 123; the first rotating shaft 123 transmits the rotational torsion to the second rotating shaft 126, and the second rotating shaft 126 transmits the rotational torque to the propeller 124.

[0142] In one embodiment, the propulsion transmission mechanism 125 further includes a bevel gear set 127, which is disposed in the liquid storage chamber 130, and the first rotating shaft 123 and the second rotating shaft 126 are transmission-connected via the bevel gear set 127. It can be understood that the bevel gear set 127 can be used to change the direction of the torque, that is, to enable the first rotating shaft 123 to transmit the torque to the second rotating shaft 126 which is not coaxially disposed therewith.

[0143] In this embodiment, the first rotating shaft 123 is perpendicular to the second rotating shaft 126, and the first rotating shaft 123 and the second rotating shaft 126 are connected by a pair of helical gears. Further, the pair of helical gears includes a first gear unit 128 and a second gear unit 129, the first gear unit 128 is connected to the end of the first rotating shaft 123 located in the liquid storage chamber 130, and the second gear unit 129 is connected to the end of the second rotating shaft 126 located in the liquid storage chamber 130, and the surfaces of the first gear unit 128 and the second gear unit 129 are both provided with inclined teeth, and the first gear unit 128 and the second gear unit 129 are vertically arranged so that the inclined teeth of each gear unit 128 and the second gear unit 129 mesh with each other.

[0144] In one embodiment, the bevel gear set 127 is soaked in the coolant, and the bevel gear set 127 is also used to stir the coolant in the liquid storage chamber 130. Furthermore, the bevel gear set 127 has teeth that are protruding compared to the gear body. During the rotation of the bevel gear set 127, the protruding teeth interact with the coolant to drive the coolant to flow. Specifically, the coolant tends to move away from the bevel gear set 127 compared to the bevel gear set 127, so that the bevel gear set 127 stirs the coolant, thereby improving the uniformity of the coolant in the liquid storage chamber 130 and transferring heat more quickly in the coolant.

[0181] It is understandable that the temperature of the motor 12 can be sensed by a temperature sensor integrated in the motor 12, or by an external temperature sensor matched with the motor 12. The temperature sensor can be an existing temperature sensor, such as an infrared temperature sensor. The temperature sensor acquires the first temperature of the motor 12 and transmits the first temperature to the electric control module 3 that is communicatively connected to the temperature sensor.

[0182] Step S2: comparing the first temperature with a first preset temperature threshold;

[0183] It can be understood that the electric control module 3 compares the value of the first temperature with the first preset temperature threshold, and the comparison process can be understood as comparing the magnitudes of temperature values ​​of the same temperature unit. The first preset temperature threshold can be a set of numbers pre-written by the user in the memory 31 of the electric control module 3, and the user can adjust the first preset temperature threshold according to actual needs.

[0184] Step S3: If the first temperature is higher than the first preset temperature threshold, controlling the transmission component 14 to transmit the coolant;

[0185] It is understandable that if the first temperature is determined to be higher than the first preset temperature threshold, it is determined that the current temperature of the motor 12 is high and needs to be cooled to prevent the motor 12 from overheating. In this embodiment, the drive pump 142 is used as an electronic pump for illustration, and the electronic control module 3 sends a start signal to the drive pump 142 of the transmission component 14, so that the transmission component 14 starts to transfer the coolant from the liquid storage chamber 130 to the working chamber 110 to cool the motor 12.

[0186] Step S4: If the first temperature is lower than the first preset temperature threshold, the driving pump 142 is controlled to stop.

[0187] It can be understood that if the first temperature is determined to be lower than the first preset temperature threshold, it is determined that the current temperature of the motor 12 is within a reasonable range, and cooling of the motor 12 can be suspended to maintain the working efficiency of the motor 12. In this embodiment, the driving pump 142 is used as an electronic pump for illustration, and the electronic control module 3 sends a stop signal to the driving pump 142 of the transmission component 14, so that the transmission component 14 stops transmitting the coolant from the liquid storage chamber 130 to the working chamber 110, thereby stopping cooling of the motor 12.

[0188] It can be understood that the heat dissipation control method of the propulsion device can intelligently adjust the cooling of the propulsion device, and adjust the temperature of the propulsion device 1 by adjusting the first preset temperature threshold. The transmission component 14 is allowed to intervene to cool the motor 12 when the temperature of the motor 12 is high, and the transmission component 14 is not allowed to intervene to cool the motor 12 when the temperature of the motor 12 is low, thereby optimizing the cooling efficiency of the propulsion device.

[0194] The memory 31 can be used to store the computer program 33 and / or modules / units. The processor 32 realizes various functions of the electric control module 3 by running or executing the computer program and / or modules / units stored in the memory 31 and calling the data stored in the memory 31.
