Description

Technical Field

[0001] This application relates to the technical field of electric motors, and in particular to an integrated water-cooled system motor. Background Technology

[0002] When a motor is running, the current flowing through the windings generates Joule heat, and heat is also released from the iron core due to eddy current and hysteresis losses. If this heat cannot be dissipated in time, the temperature will continue to rise. High temperatures will accelerate the aging of the insulation materials, leading to reduced motor performance or even damage.

[0003] The motor includes a housing, a front cover and a rear cover, a rotor and a stator. The stator is fixedly installed inside the housing, and the rotor is rotatably mounted on the front cover and the rear cover at both ends. The housing has a large area. In existing water-cooled motors, the housing and the stator are generally cooled. However, the rotor is rotatably connected to the front cover and the rear cover through bearings, and the front cover and the rear cover will also continuously generate heat. In particular, the heat generated at the rotor and the bearings is even greater, which can easily lead to a decrease in motor performance and lifespan. Summary of the Invention

[0004] To improve motor performance and lifespan, this application provides an integrated water-cooled system motor.

[0005] This application provides an integrated water-cooled system motor, which adopts the following technical solution: An integrated water-cooled motor includes a housing, a front cover, a rear cover, a stator and a rotor, and a water-cooling mechanism. The front cover and rear cover respectively have a front liquid chamber and a rear liquid chamber. The rotor is rotatably mounted on the front cover via a first bearing and on the rear cover via a second bearing. A water-cooling chamber covering the positions of the first and second bearings is coaxially formed at one end of the rotor near the rear cover. The water-cooling mechanism includes: The inlet pipe is connected to the front liquid chamber and is used to input coolant. The cooling body is enclosed on the outer shell and has an annular cooling cavity that communicates with the front liquid cavity and the rear liquid cavity; A guide assembly is used to guide the coolant located in the cooling chamber and to ensure that the coolant input from the front chamber flows around the outer casing once before entering the rear chamber. The infusion assembly is mounted on the rear cover and communicates with the rear liquid chamber and extends into the water-cooling chamber, so that the coolant located in the rear liquid chamber enters the water-cooling chamber and is then output through the infusion assembly.

[0006] By adopting the above technical solution, coolant is introduced into the front liquid chamber through the inlet pipe to cool the front end cover and the outer side of the first bearing. The coolant in the front liquid chamber enters the cooling chamber, and the guide assembly guides the coolant so that it surrounds the outer shell and cools the outer shell and the stator inside the outer shell. The coolant in the cooling chamber enters the rear liquid chamber to cool the rear end cover and the outer side of the second bearing. The coolant in the rear liquid chamber enters the water cooling chamber through the liquid delivery assembly to cool the rotor, the inner side of the first bearing, and the inner side of the second bearing. Finally, the coolant is output through the liquid delivery assembly, thereby realizing water circulation.

[0007] The coolant circulates by passing sequentially through the front liquid chamber, cooling chamber, rear liquid chamber, and water-cooling chamber before being output through the liquid delivery assembly. This allows for simultaneous cooling of multiple components of the motor, improving its performance and lifespan. Due to the large size of the housing and stator, the guide assembly further enhances cooling efficiency, thus improving the motor's performance and lifespan.

[0008] Because the rotor has a slender structure, the water-cooling cavity can better cool the rotor and the first and second bearings, thereby further improving the cooling effect of the motor. However, the opening of the water-cooling cavity will reduce the strength of the rotor. Therefore, the liquid enters the water-cooling cavity and then exits from the liquid delivery assembly. Thus, the liquid can support the rotor and improve its strength, which can further improve the performance and life of the motor.

[0009] Optionally, the cooling chamber is connected to the front liquid chamber via a first channel and to the rear liquid chamber via a second channel, and the guide assembly includes: A separator is disposed on the cooling body and located within the cooling cavity. The separator is used to separate the coolant and such that the first channel and the second channel are located on opposite sides of the separator. Multiple guide elements 1 and multiple guide elements 2 are spaced apart and located on opposite side walls of the cooling chamber. The guide element 1 extends between two adjacent guide elements 2 and the guide element 2 extends between two adjacent guide elements 1, and they cooperate to form a flow channel. The coolant input through the first channel flows in a zigzag shape through the guide channel, and the coolant enters the second channel after circling the outer shell.

[0010] By adopting the above technical solution, the coolant enters the cooling chamber through the first channel, and then forms a zigzag flow trajectory through the guide channel, so that the coolant circulates around the outer shell and then enters the rear liquid chamber through the second channel. This can greatly extend the movement time and amount of coolant in the outer shell, thereby greatly improving the cooling effect on the outer shell and stator, and improving the performance and life of the motor.

[0011] Optionally, the infusion assembly includes: The infusion chamber is mounted on the rear end cover via a connector and has an annular infusion chamber that communicates with the rear liquid chamber. The liquid outlet pipe is installed on the liquid delivery system; An infusion tube is installed on the infusion fluid and connected to the outlet tube. The infusion tube extends coaxially into the water-cooling cavity and forms an annular flow chamber with the inner wall of the water-cooling cavity. The coolant entering the infusion cavity passes through the flow chamber and then enters the infusion tube and is output through the outlet tube to achieve coolant circulation.

[0012] By adopting the above technical solution, the coolant located in the rear liquid chamber enters the delivery chamber, the coolant enters the flow chamber, and then the coolant is output through the delivery pipe and the outlet pipe. The delivery pipe allows the coolant to enter the water-cooling chamber and then be output through the delivery pipe. Thus, the flow direction of the coolant can be changed by relying solely on the delivery pipe. The structure is simple and stable. At the same time, the annular delivery chamber and flow chamber can better cover the rotor, the first bearing, and the second bearing for cooling, further improving the cooling effect and improving the performance and life of the motor.

[0013] Furthermore, after the infusion tube enters the flow chamber from the infusion chamber, the flow space becomes smaller, which increases the coolant pressure. As the coolant pressure increases, the cooling effect of the coolant is further improved, thus further improving the performance and lifespan of the motor.

[0014] Meanwhile, the cooling fluid also enters the flow chamber and then the infusion pipe. The coolant in the infusion pipe can support the infusion pipe, and the infusion pipe and the coolant in the flow chamber can support and position the rotor. The cooperation between the infusion pipe and the coolant can greatly improve the stability of the infusion pipe delivery and the rotor operation, thereby improving the performance and life of the motor.

[0015] Optionally, the infusion chamber is connected to one end of the infusion fluid, a cap is detachably installed on the infusion fluid, a connecting pipe is provided on the cap, and the outlet pipe and the infusion pipe are detachably connected to the connecting pipe respectively. Both the first and second channels have cleaning holes that communicate with the outside world, and cleaning screws for sealing the cleaning holes are threaded onto the cleaning holes.

[0016] By adopting the above technical solution, the design of the cap and connecting pipe makes it easy to connect, disassemble and replace the liquid outlet pipe and the liquid delivery pipe, and makes it easy to replace and maintain the structure of the cooling mechanism, thereby further improving the cooling effect and increasing the performance and life of the motor.

[0017] The pipes of the water-cooling mechanism are relatively narrow, which can easily lead to blockages. Therefore, when a blockage occurs, the cleaning screw is removed from the cleaning hole, and then liquid or gas is introduced through the cleaning hole to clear the blockage. This greatly improves the convenience of the cleaning process. After cleaning, the cleaning screw is threaded back onto the cleaning hole to seal it, reducing the resistance encountered by the liquid movement during cooling, thereby further improving the performance and lifespan of the motor.

[0018] Optionally, the front liquid chamber and the rear liquid chamber are both annular and are respectively opened around the periphery of the first bearing and the second bearing, and the infusion tube extends to the end of the water-cooling chamber away from the rear end cover.

[0019] By adopting the above technical solution, the annular front liquid chamber and rear liquid chamber can better cover and cool the first and second bearings, thereby improving the cooling effect on both. At the same time, the liquid delivery pipe extends to the end of the water-cooling chamber away from the rear end cover, which allows the annular flow chamber to extend to the rear end cover, thereby further improving the cooling effect and improving the performance and life of the motor.

[0020] Optionally, it may also include a support mechanism and / or an adjustment mechanism. The support mechanism is detachably mounted on one end of the infusion tube located in the water-cooling chamber and is supported and positioned on the water-cooling chamber. The adjustment mechanism is mounted on the connecting pipe and communicates with the outlet pipe to create a certain pressure when the coolant is cooled.

[0021] By adopting the above technical solution, the support mechanism can support and position the end of the infusion tube that extends into the water-cooling chamber, thereby improving the stability of the infusion tube during operation. At the same time, the adjustment mechanism can make the flowing coolant form a certain pressure, which improves the cooling effect and the support and positioning effect on the rotor and the infusion tube, thereby further improving the motor performance and life.

[0022] Optionally, the support mechanism includes: The mounting sleeve can be detachably installed on the end of the infusion tube located inside the water-cooling chamber. The support component is mounted on the mounting sleeve and, under the action of elasticity, presses against the end of the water-cooling cavity away from the rear end cover for positioning; Multiple support legs are arranged in a circumferential array around the axis of the mounting sleeve and extend to the side near the water-cooling cavity. Each support leg is rotatably provided with a ball bearing that supports rolling on the water-cooling cavity.

[0023] By adopting the above technical solution, the length of the water-cooling cavity is relatively long. In order to improve the cooling effect, the length of the infusion tube is increased. However, the pressure of the liquid on the infusion tube is relatively large, especially the pressure on the end of the infusion tube away from the liquid. Since the infusion tube is fixed only by the connection with the liquid, the connection between the infusion tube and the liquid is easily damaged, resulting in low stability of the infusion tube during operation, which reduces the performance and life of the motor.

[0024] Connect the mounting sleeve to one end of the infusion tube, then place multiple support legs into the water-cooling chamber. The ball bearings roll on the water-cooling chamber. Next, connect the other end of the infusion tube to the connecting pipe. Push the infusion tube and support assembly closer to one end inside the water-cooling chamber until the cap is fixedly installed on the infusion tube. The multiple support legs on the water-cooling chamber can position the infusion tube circumferentially, and the support assembly presses against the end of the water-cooling chamber away from the rear end cap under the action of elasticity for positioning. This can greatly improve the positioning effect of the infusion tube.

[0025] Therefore, by installing the sleeve and support assembly, the end of the infusion tube away from the infusion fluid can be supported and positioned, that is, the infusion tube can be positioned axially. Multiple legs can position the infusion tube circumferentially. At the same time, the rotor can also be positioned through the reverse force. Moreover, when the rotor rotates, it is connected to the legs through the ball bearings, which reduces the adverse effects of the rotor rotation on the support, improves the stability of the motor during operation, and improves the performance and life of the motor.

[0026] Furthermore, when the motor operates and causes the infusion tube to vibrate along its own axis, the elastic support components can also provide cushioning, thereby further improving the stability of the motor during operation and enhancing the motor's performance and lifespan.

[0027] Optionally, the support component includes: The sliding tube is installed on the mounting sleeve. The sliding rod is slidably mounted on the inner wall of the sliding tube; The support platform, mounted on the sliding rod, has a frustum-shaped guide surface on its side wall near the mounting sleeve, used to guide the coolant into the delivery pipe. The guide surface, sliding pipe, sliding rod, and mounting sleeve cooperate to form a system for the coolant to enter the delivery pipe. Enter the liquid chamber; The support sleeve is slidably mounted on the mounting sleeve. The elastic element is located inside the support sleeve and its two ends are connected to the support platform and the mounting sleeve, so that the support sleeve and the support platform are respectively pressed against the end of the water cooling cavity away from the second bearing and the sliding tube for positioning under the action of elastic force.

[0028] By adopting the above technical solution, the elastic element pushes the support sleeve against the water-cooling cavity for positioning, and the support platform against the sliding tube for positioning. The elastic element is used for buffering during vibration. Simultaneously, when the coolant moves to the support platform, the guiding surface allows the coolant to enter the infusion pipe more quickly and conveniently. When the coolant contacts the guiding surface, it can push the support platform and sliding rod away from the sliding tube, thereby increasing... The increased volume of the inlet chamber allows more coolant to enter the delivery pipe, effectively supporting the pipe. At the same time, the elastic element and support platform create resistance to the coolant, generating pressure in the coolant in front of the support platform, further improving the cooling effect and extending the motor's performance and lifespan.

[0029] Optionally, the adjustment mechanism includes: The regulating pipe is detachably connected to the connecting pipe and its interior is in communication with the connecting pipe; the liquid outlet pipe is in communication with the interior of the regulating pipe. The sealing block is used to seal the end of the regulating pipe away from the connecting pipe; An adjusting block is slidably disposed inside the adjusting pipe and connected to the sealing block through an elastic mechanism, such that the adjusting block is initially located on the side of the outlet pipe close to the connecting pipe and cuts off the adjusting pipe and the outlet pipe. The coolant input into the adjusting pipe pushes the adjusting block closer to the outlet pipe. When the coolant thrust reaches a certain value, it pushes the adjusting block to move to the side of the outlet pipe away from the connecting pipe and connects the adjusting pipe and the outlet pipe. The regulating block has multiple regulating holes evenly distributed on it. A waterproof and breathable membrane is provided on the side of the regulating block near the connecting pipe. The waterproof and breathable membrane allows gas to pass through the regulating holes and the liquid outlet pipe while blocking liquid from passing through.

[0030] By adopting the above technical solution, after the coolant enters, it pushes the air into the regulating pipe. Then, the air is output through the waterproof and breathable membrane, the regulating hole, and the outlet pipe, allowing the air to be discharged as quickly as possible, which facilitates the flow of coolant for cooling. After the coolant is output from the connecting pipe, it is blocked by the regulating block, thus creating a certain pressure in the coolant. Under the action of hydraulic pressure, the coolant pushes the regulating block to move against the elastic force of the elastic mechanism until the regulating pipe and the output pipe are connected, allowing the coolant to be output through the output pipe. This creates a certain pressure in the coolant during cooling, which can improve the cooling effect on the motor and also provide a certain support force for the liquid delivery pipe and rotor in the water-cooling cavity, further improving the stability of the motor during operation and increasing the performance and life of the motor.

[0031] Meanwhile, compared to the pressure relief structure that uses a detector and electric control, this application achieves control through the elastic force of an elastic mechanism, which can better improve the adjustment effect, making the pressure and support force of the coolant more stable during cooling, thereby improving the performance and life of the motor.

[0032] Optionally, the resilient mechanism includes: The movable block is slidably positioned inside the regulating pipe and located on the side of the regulating block away from the connecting pipe; The guide rod is mounted on the adjusting block and slides through the moving block. An elastic element is fitted onto the guide rod and its two ends are connected to the adjusting block and the moving block; The moving component is used to adjust the position of the moving block.

[0033] By adopting the above technical solution, the adjusting block moves under the guidance of the guide rod, and the elastic element provides elastic force. The adjusting block overcomes the elastic force of the elastic element to move. At the same time, the moving component can also adjust the position of the moving block as needed to adjust the elastic force on the adjusting block, which can better realize the adjustment of coolant pressure and support force, and improve the performance and life of the motor.

[0034] Optionally, the moving component includes: The movable tube is threadedly connected to the sealing block and slidably sleeved on the guide rod; The adjusting ring is rotatably mounted on the side wall of the moving block near the blocking block and is magnetically attached to the adjusting tube. The locking element is threaded onto the regulating pipe and presses against the sealing block for positioning.

[0035] By adopting the above technical solution, adjustment is required. Tightening the locking part disengages it from the blocking block, and rotating the adjusting tube drives the adjusting ring and the moving block to move. After adjustment, tightening the locking part presses against the blocking block for positioning, thereby adjusting the position of the moving block. During installation, the elastic part is fixedly connected to the moving block and the adjusting block, and then the moving block and the adjusting block are slidably installed into the adjusting tube. Pushing the adjusting block causes the adjusting ring on the moving block to adhere to the adjusting ring for positioning. At the same time, the rotation of the adjusting tube does not drive the moving block to rotate, thus making the adjustment process more stable and reducing the risk of interference during adjustment.

[0036] In summary, this application includes at least one of the following beneficial technical effects: 1. The coolant circulates by passing through the front liquid chamber, cooling chamber, rear liquid chamber, and water-cooling chamber in sequence before being output through the liquid delivery assembly. This allows for simultaneous cooling of multiple components of the motor, improving its performance and lifespan. Due to the large size of the housing and stator, the guide assembly can better cool the housing and stator, improving the cooling effect and further enhancing the motor's performance and lifespan.

[0037] 2. The water-cooling chamber can better cool the rotor, the first bearing, and the second bearing, thereby further improving the cooling effect of the motor. At the same time, the liquid enters the water-cooling chamber and is then output from the liquid delivery assembly, so the liquid can support the rotor, improve the rotor strength, and thus further improve the performance and life of the motor.

[0038] 3. The support mechanism enables the end of the infusion tube extending into the water-cooling chamber to be supported and positioned, improving the stability of the infusion tube during operation; at the same time, the adjustment mechanism enables the flowing coolant to form a certain pressure, improving the cooling effect and the support and positioning effect on the rotor and infusion tube, thereby further improving the motor performance and lifespan.

[0041] The following provides a further detailed description of this application.

[0042] This application discloses an integrated water-cooled system motor.

[0043] Example 1, referring to Figures 1-4 The integrated water-cooled motor includes a housing 11, a front cover 12, a rear cover 13, a stator 14, a rotor 2, and a water-cooling mechanism 3. The front cover 12 and the rear cover 13 are fixedly installed on both ends of the housing 11 by screws or nuts. The front cover 12 and the rear cover 13 have mounting groove 1 21 and mounting groove 22 respectively on opposite ends. The first bearing 23 is installed in the mounting groove 1 21 with an interference fit, and the second bearing 24 is installed in the mounting groove 22 with an interference fit. The rotor 2 is interference-fitted with the first bearing 23 and the second bearing 24 at both ends, thereby realizing the rotatable connection between the rotor 2 and the front cover 12 and the rear cover 13. The stator 14 is fixedly installed inside the housing 11. The water-cooling mechanism 3 is used to cool the housing 11, the front cover 12, the rear cover 13, the stator 14, and the rotor 2. The front cover 12 and the rear cover 13 are integrally cast and then assembled.

[0044] The front cover 12 and the rear cover 13 are respectively provided with a front liquid chamber 15 and a rear liquid chamber 16 at opposite ends. Both the front liquid chamber 15 and the rear liquid chamber 16 are annular and their axes coincide with the axis of the rotor 2. The front liquid chamber 15 is arranged around the first bearing 23 and facilitates the cooling of the first bearing 23. The rear liquid chamber 16 is arranged around the second bearing 24 and facilitates the cooling of the second bearing 24. The two ends of the rotor 2 extend to the outside of the front cover 12 and the rear cover 13 respectively. The length of the rotor 2 extending out of the front cover 12 is greater than the length of the rotor 2 extending out of the rear cover 13. At the same time, the end of the rotor 2 extending out of the front cover 12 is used to connect with the external structure to realize the drive.

[0045] A sealing plate 19 for sealing the front liquid chamber 15 is fixedly installed on the front cover 12 by screws. A water-cooling chamber 25 is coaxially opened at one end of the rotor 2 near the rear cover 13. The water-cooling chamber 25 passes through the second bearing 24 and the first bearing 23 and extends to the side of the first bearing 23 away from the second bearing 24, so as to achieve cooling coverage of the positions of the first bearing 23 and the second bearing 24.

[0046] Reference Figure 1 , Figures 5-7 The water-cooling mechanism 3 includes an inlet pipe 31, a cooling body 32, a guide assembly 4, and a liquid delivery assembly 5. The inlet pipe 31 is fixedly installed on the side wall of the front cover 12, and the inlet pipe 31 communicates with the front liquid chamber 15 through a through hole 311 and is equipped with an opening and closing control valve 312. The cooling body 32 includes two mounting parts 33 and two sealing parts 34. The two mounting parts 33 are coaxially fixedly installed on the outer wall of the outer shell 11 and are arranged opposite to each other along the axis of the outer shell 11. The opposite ends of the two mounting parts 33 and the outer wall of the outer shell 11 form a cooling chamber 35 around the outer shell 11. The two mounting parts 33, the two sealing parts 34, and the outer shell 11 are integrally cast to form the cooling chamber 35. Integral casting helps to reduce noise, improve heat conduction efficiency, operational stability, and service life.

[0047] Reference Figure 2 , Figures 5-7 Both sealing parts 34 are semi-circular. After being spliced ​​together, the two sealing parts 34 are fixed to the two mounting parts 33 by screws. They are used to seal the cooling cavity 35 to form a closed structure. The cooling cavity 35 is coaxially arranged with the outer shell 11. The cooling cavity 35 is connected to the front liquid cavity 15 through the first channel 36 and to the rear liquid cavity 16 through the second channel 37. The first channel 36 and the second channel 37 are staggered. At the same time, the first channel 36 and the second channel 37 have the same shape and structure. The following explanation will take the first channel 36 as an example.

[0048] The first channel 36 includes a first channel 38 and a second channel 39 that are interconnected. The second channel 39 and the outer casing 11 are parallel in axis, and the second channel 39 passes through the mounting part 33 near the front liquid chamber 15 and extends into the front cover 12. The first channel 38 and the second channel 39 are perpendicular in axis, and the first channel 38 is connected to the second channel 39 and extends into the front liquid chamber 15. The cooling chamber 35 and the front liquid chamber 15 are connected through the first channel 38 and the second channel 39. At the same time, a blocking block 151 is fixedly installed in the front liquid chamber 15. The blocking block 151 is located between the first channel 38 and the through hole 311, so that the coolant entering the front liquid chamber 15 through the inlet pipe 31 through the through hole 311 circulates around the first bearing 23 once and then exits from the first channel 38.

[0049] Meanwhile, a cleaning hole 391 communicating with the outside is provided on the front cover 12 at the connection between channel 1 38 and channel 2 39. A cleaning screw 392 for sealing is threaded onto the cleaning hole 391. When the pipeline of the water cooling mechanism 3 is blocked, the cleaning screw 392 can be removed from the cleaning hole 391 and then cleaned through the cleaning hole 391, which improves the convenience of the cleaning process.

[0050] The guide assembly 4 is used to guide the coolant located in the cooling chamber 35, so that the coolant input through the first channel 36 surrounds the outer shell 11 once and then enters the rear liquid chamber 16 through the second channel 37. The guide assembly 4 includes a separator 41, a plurality of guide elements 42 and a plurality of guide elements 43. The separator 41 is arranged along the axis of the outer shell 11 and is located between the first channel 36 and the second channel 37. The separator 41 is used to prevent the cooling blades entering through the first channel 36 from flowing directly to the second channel 37, so that the coolant surrounds the outer shell 11 once and then enters the second channel 37. The plurality of guide elements 42 and the plurality of guide elements 43 are arranged in a circumferential array around the axis of the cooling chamber 35. The guide elements 42 and the guide elements 43 are respectively fixedly installed on the opposite side wall of the two mounting parts 33, and the guide elements 42, the guide elements 43 and the mounting parts 33 are flush with the side wall away from the outer shell 11.

[0051] Guide member 42 extends between two adjacent guide members 43, guide member 43 extends between two adjacent guide members 42, or guide member 43 extends between guide member 42 and separator 41. Multiple guide members 42 and multiple guide members 43 cooperate to form a flow channel. The coolant input into the first channel 36 flows in a zigzag pattern through the flow channel, and the coolant enters the second channel 37 after circling the outer casing 11 once. This makes the coolant stay in the outer casing 11 for a longer time, thus improving the cooling effect on the outer casing 11 and stator 14.

[0052] Reference Figures 2-4The infusion assembly 5 is mounted on the rear cover 13 and communicates with the rear liquid chamber 16 and extends into the water cooling chamber 25, so that the coolant in the rear liquid chamber 16 enters the water cooling chamber 25 and is then output through the infusion assembly 5. The infusion assembly 5 includes a liquid infusion 51, an outlet pipe 52 and an infusion pipe 53. The liquid infusion 51 is annular and coaxial with the rotor 2. The outer wall of the liquid infusion 51 is mounted on the rear cover 13 through a connector 18.

[0053] The connector 18 includes an annular portion 181 and a support portion 182. The annular portion 181 is fixedly mounted on the rear end cover 13 by screws. The annular portion 181 is coaxially arranged with the rotor 2 and is used to block the rear liquid chamber 16. The liquid delivery 51 is located on the side of the annular portion 181 away from the rear end cover 13. Multiple support portions 182 are arranged at intervals, and each support portion 182 is fixedly connected to the annular portion 181 and the liquid delivery 51 at both ends. Each support portion 182 has a flow channel 183 that communicates with the rear liquid chamber 16 and the liquid delivery chamber 54.

[0054] The fluid delivery 51 has a circular delivery chamber 54 coaxially formed at one end away from the support part 182. A cover 17 is fixedly installed on the fluid delivery 51 to seal the delivery chamber 54. A connecting pipe 56 with both ends extending into and out of the delivery chamber 54 is fixedly installed on the cover 17. The outlet pipe 52 is fixedly installed on the end of the connecting pipe 56 located outside the delivery chamber 54 and is used to output coolant.

[0055] One end of the infusion tube 53 is inserted into the end of the connecting tube 56 that extends into the infusion chamber 54. The infusion tube 53 is coaxially arranged with the rotor 2. The outer diameter of the infusion tube 53 is smaller than the diameter of the water-cooling chamber 25. The infusion tube 53 extends coaxially into the water-cooling chamber 25, passing through the second bearing 24 and the first bearing 23, and extends to the side of the first bearing 23 away from the second bearing 24, that is, to the side of the water-cooling chamber 25 away from the second bearing 24. The infusion tube 53 and the inner wall of the water-cooling chamber 25 cooperate to form an annular flow chamber 55. At the same time, the end of the water-cooling chamber 25 near the infusion chamber 54 has a guide rounded corner to facilitate the flow of coolant. The coolant in the rear liquid chamber 16 enters the infusion chamber 54 through the flow channel 183. The coolant in the infusion chamber 54 flows into the flow chamber 55. After entering the infusion tube 53, the coolant is output through the connecting tube 56 and the outlet tube 52, thereby realizing the circulation of coolant.

[0056] The working principle of this application embodiment is as follows: The coolant in the inlet pipe 31 enters the front liquid chamber 15, circulates once, and then enters the cooling chamber 35 through the first channel 36 to cool the outside of the first bearing 23. Under the guidance of the guide assembly 4, the coolant moves in a zigzag pattern and, after circling once, enters the rear liquid chamber 16 through the second channel 37 to cool the outer casing 11 and the stator 14. After flowing in the rear liquid chamber 16, the coolant enters the delivery chamber 54 to cool the outside of the second bearing 24. After passing through the flow chamber 55, the coolant is output through the delivery pipe 53 and the outlet pipe 52, thereby cooling the rotor 2 and cooling the inside of the first bearing 23 and the second bearing 24. This improves the cooling effect on multiple structures of the motor. At the same time, the coolant can also provide some support and positioning for the rotor 2 and the delivery pipe 53, improving the performance and lifespan of the motor.

[0057] Example 2, refer to Figures 2-4 , Figures 8-9 The difference between this embodiment and embodiment 1 is that it also includes a support mechanism 6 and / or an adjustment mechanism 8. The support mechanism 6 is detachably mounted on one end of the infusion pipe 53 located inside the water-cooling chamber 25 and is supported and positioned on the water-cooling chamber 25. The adjustment mechanism 8 is mounted on one end of the connecting pipe 56 located outside the infusion chamber 54. The adjustment mechanism 8 makes the coolant form a certain pressure when cooling, which can improve the cooling effect and also effectively support the infusion pipe 53 and the rotor 2, making the cooling process and motor operation more stable. Therefore, by having one or both of the support mechanism 6 and the adjustment mechanism 8, the performance and life of the motor are further improved.

[0058] The support mechanism 6 includes a mounting sleeve 61, a support component 7, and multiple legs 62. The mounting sleeve 61 is fitted onto one end of the infusion tube 53 located inside the water-cooling cavity 25, and a positioning ring 64 is coaxially and integrally provided on the inner side wall of one end of the mounting sleeve 61. The inner diameter of the positioning ring 64 is equal to the inner diameter of the infusion tube 53, and the positioning ring 64 abuts against the infusion tube 53 for positioning.

[0059] The support assembly 7 is mounted on the mounting sleeve 61 and is positioned by pressing against the end of the water-cooling cavity 25 away from the rear end cover 13 and the second bearing 24 under the action of elasticity. The support assembly 7 is located on the side of the mounting sleeve 61 away from the infusion tube 53. Multiple legs 62 are fixedly mounted on the support assembly 7, and the multiple legs 62 are arranged in a circumferential array around the axis of the mounting sleeve 61 and extend to the side close to the water-cooling cavity 25. Each leg 62 is rotatably mounted with a ball bearing 63 that supports the rolling of the ball bearing 63 on the water-cooling cavity 25.

[0060] The support assembly 7 includes a sliding tube 71, a sliding rod 72, a support platform 73, a support sleeve 74, and an elastic element 75. The sliding tube 71 and the sliding rod 72 are correspondingly arranged and are spaced apart. The sliding tube 71 is fixedly installed on the mounting sleeve 61 and is arranged along the axis of the infusion tube 53. The sliding rod 72 is coaxially slidably installed on the sliding tube 71. The support platform 73 is fixedly installed on one end of the multiple sliding rods 72 away from the mounting sleeve 61. The support platform 73 is connected to one end of the sliding rod 72 and is located between the multiple sliding rods 72, forming a frustum-shaped guide surface 76. The guide surface 76 protrudes towards the infusion tube 53 and is used to guide the coolant and make the coolant flow into the infusion tube 53.

[0061] The guide surface 76, sliding tube 71, sliding rod 72 and mounting sleeve 61 cooperate to form an inlet chamber 77 for coolant to enter the inlet pipe 53; the support sleeve 74 and the support platform 73 are respectively provided with a first groove 78 and a second groove 79, and the support platform 73 is slidably installed on the first groove 78; multiple elastic elements 75 are arranged at intervals, and the elastic elements 75 can be springs or spring sheets, and the elastic elements 75 are connected to the first groove 78 and the second groove 79, and the multiple elastic elements 75 are located in the first groove 78 and the second groove 79 to achieve protection.

[0062] The end of the support sleeve 74 facing away from the support platform 73 is pressed against the end of the water-cooling cavity 25 away from the rear end cover 13 under the elastic force of the elastic element 75 for positioning. At this time, the support platform 73 is positioned against the sliding tube 71. As the amount of coolant increases, the thrust on the support platform 73 and the guide surface 76 increases, causing the support platform 73 to move against the elastic force of the elastic element 75, allowing more coolant to enter the liquid delivery pipe 53. This also creates a certain pressure when the coolant is cooling, improving the cooling effect of the coolant and the support effect on the rotor 2, thereby improving the performance and life of the motor.

[0063] Reference Figure 2 , Figure 4 , Figure 9 The regulating mechanism 8 includes a regulating pipe 81, a blocking block 82, and a regulating block 83. The regulating pipe 81 is detachably connected to the end of the connecting pipe 56 located outside the infusion chamber 54. The blocking block 82 is integrally disposed on the end of the regulating pipe 81 away from the connecting pipe 56 and is used to block the regulating pipe 81. One end of the outlet pipe 52 is fixedly installed on the side wall of the regulating pipe 81 and communicates with the inside of the regulating pipe 81. The regulating block 83 is slidably installed inside the regulating pipe 81 along the axis of the regulating pipe 81, and the regulating block 83 is adapted to the inner side wall of the regulating pipe 81, so that the regulating pipes 81 located on both sides of the regulating block 83 are independent of each other.

[0064] The adjusting block 83 is connected to the blocking block 82 via the elastic mechanism 9, causing the adjusting block 83 to tend to be close to the connecting pipe 56. In the initial state, the adjusting block 83 is located between the outlet pipe 52 and the connecting pipe 56, and is used to cut off the adjusting pipe 81 and the outlet pipe 52. As the coolant volume increases, the thrust on the adjusting block 83 increases, causing the adjusting block 83 to move away from the connecting pipe 56 until the adjusting block 83 moves to the side of the outlet pipe 52 away from the connecting pipe 56, thus connecting the adjusting pipe 81 and the outlet pipe 52, and the coolant is output through the outlet pipe 52. At the same time, the adjusting block 83 is provided with multiple adjusting holes 84. A waterproof and breathable membrane 85 is bonded and installed on the end of the adjusting block 83 near the connecting pipe 56. The waterproof and breathable membrane 85 covers all the adjusting holes 84, allowing the air entering the adjusting pipe 81 to be discharged through the waterproof and breathable membrane 85, the adjusting holes 84 and the outlet pipe 52, while blocking the coolant from passing through.

[0065] The elastic mechanism 9 includes a movable block 91, a guide rod 92, an elastic element 93, and a moving assembly 94. The movable block 91 is slidably mounted on the regulating pipe 81 and located on the side of the outlet pipe 52 away from the connecting pipe 56. The guide rod 92 is fixedly mounted on the regulating block 83 and slidably passes through the movable block 91. The guide rod 92 is located between multiple regulating holes 84. The elastic element 93 is a spring, which is fixedly mounted on the regulating block 83 and the movable block 91 and is sleeved on the guide rod 92 for positioning. The moving assembly 94 is used to adjust the position of the movable block 91, thereby adjusting the elastic force of the regulating block 83.

[0066] The moving component 94 includes a moving tube 95, an adjusting ring 96, and a locking element 97. The moving tube 95 is threadedly connected to the sealing block 82 and extends into the adjusting tube 81 and slides onto the guide rod 92. The adjusting ring 96 is rotatably mounted on the side wall of the moving block 91 near the sealing block 82 and is magnetic and adsorbed onto the moving tube 95 for positioning. The locking element 97 is a locking nut, which is threadedly connected to the moving tube 95 and presses against the sealing block 82 for positioning.

[0067] The elastic element 93 is sleeved onto the guide rod 92 and its two ends are fixedly connected to the adjusting block 83 and the moving block 91. The moving block 91, the elastic element 93 and the adjusting block 83 are placed into the moving tube 95. Pushing the adjusting block 83 will push the moving block 91 against the moving tube 95, so that the adjusting ring 96 is attracted and positioned with the moving tube 95. At the same time, by pushing the guide rod 92 through the moving tube 95 with a tool, the moving block 91, the elastic element 93 and the adjusting block 83 can be removed for replacement, which improves the convenience of installation and replacement of the adjusting mechanism 8.

[0068] The working principle of this application embodiment is as follows: The mounting sleeve 61 is fitted onto one end of the infusion tube 53. Multiple support legs 62 are placed inside the water-cooling chamber 25, and the infusion tube 53 is moved. The other end of the infusion tube 53 is then inserted into the connecting tube 56 for positioning. Finally, the cap 17 is fixedly installed onto the infusion tube 51, so that the support sleeve 74 is pressed against the water-cooling chamber 25 for positioning under the elastic force of the elastic element 75, and the support platform 73 is positioned against the sliding tube 71. This facilitates the disassembly and reassembly of the infusion tube 53 and the connecting tube 56, while also improving the stability of the infusion tube 53 after installation.

[0069] The coolant moves through the flow chamber 55 to the mounting sleeve 61, and then enters the delivery pipe 53 through the inlet chamber 77. As the amount of coolant increases, the thrust on the support platform 73 and the guide surface 76 increases, causing the support platform 73 to move against the elastic force of the elastic element 75. This allows more coolant to enter the delivery pipe 53, and also creates a certain pressure during the cooling process, improving the cooling effect of the coolant and the support effect on the rotor 2 and the delivery pipe 53, thereby improving the performance and lifespan of the motor.

[0070] After the coolant enters, it pushes the air through the waterproof and breathable membrane 85, the regulating hole 84, and the outlet pipe 52 to be discharged. The coolant enters the regulating pipe 81, and the regulating block 83, under the elastic force of the elastic element 93, blocks the flow of coolant, so that the coolant forms a certain pressure. As the thrust of the coolant on the regulating block 83 increases, it pushes the regulating block 83 away from the connecting pipe 56 until the regulating block 83 moves to the side of the outlet pipe 52 away from the connecting pipe 56, so that the regulating pipe 81 and the outlet pipe 52 are connected, and the coolant is output through the outlet pipe 52. The coolant forms a certain pressure during cooling, which can improve the cooling effect and also effectively support the liquid delivery pipe 53 and the rotor 2, making the cooling process and motor operation more stable, and further improving the performance and life of the motor.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
