Description

Technical Field

[0001] The present invention relates to the technical field of water pumps for new energy vehicles, and in particular to a cooling water pump for heat dissipation in new energy vehicles. Background Art

[0002] In automotive air conditioning thermal management or battery management systems, the function of the water pump is to input coolant into system components, thereby reducing the temperature.

[0003] Among them, the invention with application number CN202311429189.1 discloses an electronic water pump with high heat dissipation and high stability, including a pump body installed at the bottom, a motor housing fixed to the upper end of the pump body, and a back cover fixed to the upper end of the motor housing. A stator is fixed to the inner wall of the motor housing. The electronic water pump adopts a structure that combines double-row angular contact ball bearings and deep groove ball bearings. By utilizing the characteristics of the double-row angular contact ball bearings themselves, it can withstand radial force as the main force and bidirectional axial force. In this structure, the deep groove ball bearings only bear radial force and do not bear axial force at all. Therefore, the electronic water pump using this structure is simple to assemble, reliable in operation, with a longer life and reduced noise. By adopting a split design, the components of the water pump can be easily disassembled and replaced, reducing the cost of later maintenance and use.

[0004] The existing water pump is basically composed of a motor casing and a pump body. The motor casing is connected to the pump body to form an integrated structure. Since the motor shaft in the motor casing needs to be inserted into the pump body, it drives the blades in the pump body to rotate, so that the liquid entering the cavity at the water inlet can be discharged from the water outlet to achieve circulation; since the water vapor in the cavity in the pump body will overflow into the gap of the motor shaft, after overflowing, it will flow into the motor casing, corrode the motor casing, and easily damage the structure inside the motor casing, causing damage to the overall structure of the water pump, affecting the normal operation of the water pump.

[0055] The present invention will be described in detail below with reference to the accompanying drawings.

[0056] As Figures 1-9 shown, a cooling water pump for heat dissipation of a new energy vehicle includes a pump body 10 and a motor housing 1 connected to the pump body 10. The inner side wall of the motor housing 1 is fixed with a stator 11. A rotor 12 is arranged inside the stator 11. A shaft core 13 penetrates through the middle of the rotor 12. A double-row angular contact ball bearing 14 is installed at the bottom of the motor housing 1, and a deep groove ball bearing 15 coaxially aligned with the double-row angular contact ball bearing 14 is installed at the top of the motor housing 1. It is coaxially installed between the double-row angular contact ball bearing 14 and the deep groove ball bearing 15. By adopting the rolling support of the double-row angular contact ball bearing 14 and the deep groove ball bearing 15, when the shaft core 13 rotates, the stability is better, and it is not easy to have an overload phenomenon, ensuring the normal operation of the water pump.

[0057] Furthermore, there is a gap between the motor housing 1 and the pump body 10, and a blowing fan 84 is installed in this gap. Since the pump body 10 and the motor housing 1 are connected by the shaft core 13, the sealing performance between the shaft core 13 and the pump body 10 cannot be guaranteed. Therefore, when the pump body 10 is pumping water, a small amount of water vapor will pass through the gap and enter the motor housing 1. In this solution, a blowing fan 84 is arranged between the motor housing 1 and the pump body 10, which can blow the water vapor from the pump body 10 to the outside, preventing the water vapor from entering the motor housing 1 and causing corrosion, thereby increasing the service life of the shaft core 13 inside the motor housing 1.

[0058] Specifically, the pump body 10 is provided with a water inlet 87 and a water outlet 88. A guide sleeve 8 is formed on the top of the pump body 10. The inner diameter of the guide sleeve 8 is larger than the outer diameter of the motor housing 1. The motor housing 1 includes an integrally formed bottom housing 17 and a top housing 16. An insertion hole 18 for the shaft core 13 to insert is formed on the top of the pump body 10. A bottom rolling bearing 19 is installed in the insertion hole 18. A water pump chamber 80 is formed in the pump body 10. The shaft core 13 passes through the insertion hole 18 and enters the water pump chamber 80, and rotates in the water pump chamber 80 through the insertion hole 18 of the pump body 10 and the bottom rolling bearing 19. Part of the water vapor in the water pump chamber 80 will escape outward, and there is a certain gap between the insertion hole 18 and the shaft core 13, which allows part of the water vapor in the water pump chamber 80 to overflow. In this solution, a blowing fan 84 is arranged between the motor housing 1 and the pump body 10. The blowing fan 84 is installed on the shaft core 13. When the shaft core 13 rotates, the blowing fan 84 rotates simultaneously, and can blow the water vapor from the pump body 10 to the outside. A plurality of exhaust holes 85 are formed on the side wall of the guide sleeve 8. The exhaust holes 85 are located outside the blowing fan 84. The blowing fan 84 is coaxially installed on the shaft core 13, and the blowing fan 84 can blow the water vapor oozing out of the insertion hole 18 to the exhaust holes 85 and discharge it outward.

[0059] Furthermore, the bottom housing 17 is fixedly connected to the top of the pump body 10. Bottom bolt holes 82 are formed on the top of the pump body 10. Top bolt holes 81 coaxially aligned with the bottom bolt holes 82 are formed on the bottom of the bottom housing 17. A connecting bolt 83 is installed between the top bolt holes 81 and the bottom bolt holes 82. The bottom housing 17 of the motor housing 1 is inserted into the guide sleeve 8 on the top of the pump body 10, so that the top bolt holes 81 and the bottom bolt holes 82 are coaxially aligned. The connecting bolt 83 installed in the bottom bolt holes 82 is inserted upward into the top bolt holes 81 to connect with the bottom housing 17, so that the bottom housing 17 is fixedly connected to the top of the pump body 10. Since the connecting bolt 83 has a certain length, there is a gap between the bottom housing 17 and the pump body 10 for installing the blowing fan 84.

[0060] A blade 86 is locked and connected to the bottom of the shaft core 13. The pump body 10 is formed with the water inlet 87 and the water outlet 88 communicated with the water pump chamber 80. The water inlet 87 is located at the bottom of the pump body 10, and the water outlet 88 is located at the side of the pump body 10. When cooling the equipment that needs to dissipate heat in the vehicle, the water inlet 87 of the pump body 10 is connected to the pipeline of the cold row, and the water outlet is connected to the heat conduction equipment, and the water coolant can circulate to dissipate heat from the heating equipment of the new energy vehicle.

[0061] The heating equipment can be a battery module.

[0062] The water inlet 87 and the water outlet 88 are respectively detachably installed with pipelines, and a cleaning device 2 and a detection device 6 are pluggably arranged in the pipelines; when the pipeline is blocked, the detection device 6 can be inserted into the pipeline to detect the inner wall structure of the pipeline. If it is found that there is scale or other conditions in the pipeline, the cleaning device can be inserted into the pipeline to remove the scale in the pipeline, reducing the probability of blockage.

[0063] The cleaning device 2 includes a cylinder 21. A power device 22 is arranged inside the cylinder 21. One end of the cylinder 21 is installed with a rotatable rotating disk 23. A plurality of radially arranged driving grooves 24 are formed on the outer ring wall of the rotating disk 23. A scraping block 26 is installed in the driving groove 24. A driving cavity 25 communicating with the driving groove 24 is arranged inside the rotating disk 23. An electric push rod 291 for driving the scraping block 26 to make a telescopic movement along the driving groove 24 is arranged in the driving cavity 25.

[0064] After the cylinder 21 is inserted into the pipeline 17, the rotating disk 23 installed on the cylinder 21 rotates, and the scraping block 26 can contact the inner wall of the pipeline 17 to remove scale. Also, according to the inner diameter size of the pipeline 17, the scraping block 26 can radially move along the driving groove 24 under the drive of the electric push rod 291 to adjust the position of the scraping block 26. The overall outer diameter can be adjusted to remove scale from the inner walls of pipelines 17 with different inner diameters.

[0065] Specifically, a power cavity 27 is formed inside the cylinder 21. A first storage battery 28 and a first driving motor 29 electrically connected to the first storage battery 28 are installed in the power cavity 27. One end of the cylinder 21 is installed with a driving shaft 293 in transmission connection with the first driving motor 29, and the rotating disk 23 is connected to the driving shaft 293; the other end of the cylinder 21 can be provided with a first charging port electrically connected to the first storage battery 28. Before use, the first storage battery 28 can be charged through the first charging port so that the first storage battery 28 has sufficient power for the first driving motor 29 to rotate, thereby driving the rotating disk 23 to rotate, enabling the scraping block 26 installed on the rotating disk 23 to contact the inner wall of the pipeline 17 to remove scale.

[0066] Specifically, a second storage battery 292 is arranged inside the driving cavity 25 of the rotating disk 23. The rotating disk 23 is provided with a second charging port electrically connected to the second storage battery 292. Before use, the second storage battery 292 can be charged through the second charging port so that the second storage battery 292 can supply power to the electric push rod 291 to drive the scraping block 26 to radially move along the driving groove 24 to adjust the position of the scraping block 26.

[0067] The cylinder 21 is provided with a climbing mechanism 3 that can move along the wall of the pipe 17. The climbing mechanism 3 includes a driving bar 20 formed on the outer wall of the cylinder 21. The driving bar 20 is equipped with a connecting rod. A climbing block 31 is installed on the outer end of the connecting rod. The climbing block 31 is nested with a transmission track 37 around it. The climbing mechanism 3 also includes an elastic driving member 4 connected to the climbing block 31. The elastic driving force of the elastic driving member 4 can drive the climbing block 31 to elastically expand radially along the cylinder 21 to drive the transmission track 37 to frictionally contact the wall of the pipe 17. After the cylinder 21 is inserted into the pipe 17, the wall-climbing mechanism 3 works, and the transmission track 37 frictionally contacts the pipe wall of the pipe 17, so that the cylinder 21 can move along the pipe 17; the elastic driving member 4 can also drive the connecting rod to swing according to the inner diameter of the pipe 17, so that the wall-climbing block 31 can adaptively move along the radial direction of the cylinder 21 to fit the inner wall of the pipe 17, so that the wall-climbing mechanism 3 can move in pipes 17 with different inner diameters to achieve multi-area descaling.

[0068] Preferably, the climbing block 31 is equipped with drive sprockets 32 at both ends, with a drive belt 37 nested between the two drive sprockets 32. The climbing block 31 is also equipped with a second drive motor 33 and a third battery 34 for driving the second drive motor 33, which can be charged before use. The second drive motor 33 is connected to one of the drive sprockets 32 via a drive gear 38. The second drive motor 33 drives the drive belt 37 to move under the drive of the two drive sprockets 32, thereby frictionally contacting the pipe wall and moving along the pipe wall to continue moving forward and removing scale. In addition, one long side of the climbing block 31 is equipped with multiple first guide rollers 35 spaced apart along its length, and another long side of the climbing block 31 is equipped with a support bar 39 along its length. The drive belt 37 is supported by the first guide rollers 35 and the support bar 39. During movement, the long side of the drive belt 37 does not concave, thereby increasing the contact area between the drive belt 37 and the pipe wall and further enhancing its climbing ability.

[0069] Preferably, there are two climbing blocks 31, which are arranged parallel to each other and connected to each other by bolts. The second drive motor 33, the third battery 34, the first guide roller 35 and the support bar 39 are all installed between the two climbing blocks 31 to protect them and reduce damage.

[0070] The connecting rod includes a pair of swing rods 36 arranged at intervals, one end of the swing rod 36 is rotatably connected to the drive bar 20, and the other end is rotatably connected to the climbing block 31. The two swing rods 36 are arranged parallel to each other and at intervals. The drive bar 20, the two swing rods 36 and the climbing block 31 form a parallelogram structure. The climbing block 31 ensures stability while being able to move radially along the cylinder 21 according to the inner diameter of the pipe 17.

[0071] Specifically, the elastic driving member 4 includes a driving seat 51 capable of moving along the length direction of the driving bar 20. A first connecting rod 41 is arranged between the driving seat 51 and the wall-climbing block 31. The first connecting rod 41 is rotatably connected to the driving seat 51 and the wall-climbing block 31 respectively. When the driving seat 51 moves along the length direction of the driving bar 20, the driving seat 51 and the wall-climbing block 31 are elastically connected through the first connecting rod 41. When the driving seat 51 moves, it can drive the wall-climbing block 31 to move radially along the cylinder 21 through the swing rod 36, so as to adjust the radial position of the wall-climbing block 31.

[0072] The first connecting rod 41 includes a bottom block 42 rotatably installed on the driving seat 51 and a top block 43 installed on the wall-climbing block 31. The bottom block 42 is provided with an elastic shaft 44 connected to the top block 43. The top block 43 is formed with a sliding hole 45 for the elastic shaft 44 to insert and slide. A sliding long groove 46 is opened on the side wall of the sliding hole 45. The elastic shaft 44 is provided with a guiding sliding block 47 slidably matched with the sliding long groove 46. The elastic shaft 44 is further nested with a first compression spring 48 located between the bottom block 42 and the top block 43.

[0073] In this embodiment, when the cleaning device 2 enters the area where the inner diameter of the pipeline 17 becomes larger, the inclination angle of the parallelogram structure becomes smaller and gradually tends to be rectangular, and the wall-climbing block 31 expands outwards. The elastic shaft 44 will slide along the sliding hole 45 of the top block 43, and the overall length of the first connecting rod 41 increases. On the contrary, when the cleaning device 2 enters the area where the inner diameter of the pipeline 17 becomes smaller, the inclination angle of the parallelogram structure becomes larger, and the first compression spring 48 nested on the elastic shaft 44 will be compressed to achieve the effect of elastic drive, reduce the vibration amplitude, the wall-climbing block 31 moves outwards, the elastic shaft 44 will slide along the sliding hole 45 of the top block 43, and the overall length of the first connecting rod 41 shortens. At the same time, the driving seat 51 will move in the direction away from the wall-climbing block 31.

[0074] Further, the elastic driving member 4 further includes a second driving member 5 for driving the driving seat 51 to move towards one side along the driving bar 20. The second driving member 5 includes a mounting seat 52 flush with the driving seat 51. The mounting seat 52 is provided with a guiding sleeve 53. The driving seat 51 is provided with a sliding shaft 54 capable of inserting into the guiding sleeve 53 and sliding along the axial direction of the guiding sleeve 53. A stop piece 55 is installed at the outer end of the sliding shaft 54. The sliding shaft 54 is nested with a second compression spring 56 located between the stop piece 55 and the guiding sleeve 53.

[0075] In this embodiment, when the cleaning device 2 enters the area where the inner diameter of the pipeline 17 becomes larger or smaller, the wall-climbing block 31 will swing accordingly through the swing rod 36.
