Description

Technical Field

[0001] This utility model belongs to the technical field of fluid flow control components in automotive thermal management systems, specifically relating to an integrated fluid flow pump valve device. Background Technology

[0002] Automobiles are highly integrated and complex industrial products. Each component of an automobile has unique operating temperatures and material tolerance temperature requirements. The automotive thermal management system can precisely regulate the heat exchange between the vehicle and the environment from a holistic vehicle perspective, maintaining each component within its optimal operating temperature range. Taking new energy vehicles as an example, the thermal management system mainly includes a refrigerant circuit and a coolant circuit. Components in the refrigerant circuit include the compressor, condenser, evaporator, and expansion valve, while components in the coolant circuit include the electric water pump, multi-way valve, water tank, and heater. In management, the pump is the machinery used to transport fluids, and the valve is the machinery used to change the direction of fluid flow. Typically, a fluid pump is used to transport coolant, and the coolant circulates within the automotive thermal management system by switching its direction and controlling its opening and closing through valves, heating or cooling the components.

[0003] With the development of thermal management systems for new energy electric vehicles, the integration level of thermal management systems is becoming increasingly high. Components such as pumps and valves are integrated into modules via carriers such as "valve islands" or "guide plates." This construction mode greatly saves the overall volume of components and fluid channels, and also reduces the risk of leakage in the pipelines connecting various components. Chinese patent CN117189622A discloses an integrated pump-valve device, which includes a pump; a pump housing for a pump chamber; a fluid inlet for conveying fluid into the pump chamber; multiple fluid outlet ports extending from the pump housing; an impeller for driving the fluid in the pump chamber; and a valve component rotatably mounted between the impeller and the multiple fluid outlet ports for selectively guiding the flow of fluid from the pump chamber to one or more of the multiple fluid outlet ports. Although this device integrates the pump and valve into one unit, its integration level is low, and it suffers from defects such as large size, redundant shape, and lack of integration interfaces, making it difficult to integrate with thermal management modules. Therefore, improvements to the existing device are necessary. Utility Model Content

[0005] The technical solution of this utility model is as follows: An integrated liquid flow pump valve device includes a housing, a top cover, a pumping motor assembly, an impeller, and a steering gear frame. The top cover is encapsulated on the top of the housing. The bottom surface of the housing has a water inlet.

Multiple outlet holes are circumferentially arranged on the side wall of the lower casing. An annular rotating guide plate is located on the outer side of the impeller, with a gap between the guide plate and the impeller. A water guide hole is located on the guide plate. A steering gear frame is mounted on the support step. A gear ring is located on the inner wall of the rotating guide plate. The steering gear frame is connected to the rotating guide plate and the impeller for transmission. As the rotating guide plate rotates, the water guide hole can switch and align between different outlet holes, directing the water flow in the impeller in different directions.

[0006] Furthermore, a bushing is fixedly provided at the center of the impeller, and the bushing is rotatably connected to the outside of the fixed shaft. A sliding sleeve is provided between the bushing and the fixed shaft. A one-way bearing is provided on the outside of the bushing, and the inner side of the one-way bearing is fixedly connected to the bushing. The outer side of the one-way bearing is connected to the first gear through a sleeve. The one-way bearing and the first gear are connected by a one-way transmission. When the one-way bearing rotates forward with the bushing, the first gear does not move. When the one-way bearing rotates in reverse with the bushing, the first gear rotates synchronously.

[0007] Furthermore, the steering gear set frame is installed in the upper cylinder. The steering gear set frame includes a frame body and multiple gears. The frame body includes a lower support plate, an upper support plate, and support columns. The lower support plate is installed on a support step, and the upper support plate is connected to the lower support plate in parallel by multiple support columns. A second, third, fourth, fifth, and sixth double gear are sequentially arranged around a central axis within the frame body. The central axes of these five double gears are rotatably connected to the frame body. The driving teeth of the first and second double gears... The driven gear of the second double gear meshes with the driving gear of the third double gear; the driven gear of the third double gear meshes with the driving gear of the fourth double gear; the driven gear of the fourth double gear meshes with the driving gear of the fifth double gear; the driven gear of the fifth double gear meshes with the driving gear of the sixth double gear; the central axis of the sixth double gear passes downward through the lower support plate; and the driven gear of the sixth double gear meshes with the gear ring on the inner wall of the rotating guide plate at the bottom of the lower support plate.

[0008] Furthermore, the pumping motor assembly includes a stator magnet, a stator plate, a permanent magnet, and a rotor magnet. The stator plate is provided with a stator magnet and is connected to the bottom surface of the upper cover. The rotor magnet is provided with a permanent magnet, and the permanent magnet and the stator magnet are positioned correspondingly. The rotor magnet is a circular plate type, and the core of the rotor magnet is locked to the shaft sleeve of the impeller. When the stator plate is energized, the rotor magnet and the permanent magnet drive the shaft sleeve and the impeller to rotate forward or in reverse.

[0009] Furthermore, the water guide hole of the rotating guide plate is an arc-shaped hole that penetrates the side wall of the rotating guide plate.

[0011] Furthermore, the lower cylinder of the shell is provided with three water outlets on its circumferential surface, and the circumferential angle between the water outlets is 100-120 degrees.

[0012] Furthermore, the upper cover is provided with an electrical connector, through which power can be supplied to the stator plate.

[0013] The beneficial effects of this utility model are as follows: This utility model integrates the water pump and valve body into a single structure, eliminating the need for pipe connections between the pump and valve. This not only reduces the risk of pipe leakage but also significantly reduces the size and manufacturing cost of the pump and valve assembly, offering advantages such as lightweight design and high integration. Based on the pump, a steering gear frame controlling the rotation of the rotating guide plate is connected to the impeller drive. The rotor magnet drives the impeller and shaft sleeve to rotate forward and backward. When the impeller rotates forward, water is pumped in normally, and the first gear remains stationary. When the impeller and shaft sleeve rotate in reverse, the shaft sleeve drives the one-way bearing to rotate in reverse under the action of the one-way bearing. The one-way bearing meshes with the first gear, causing the first gear to rotate. The first gear, acting as the driving gear, transmits power sequentially to the second, third, fourth, fifth, and sixth double gears, causing the sixth double gear to drive the rotating guide plate. During rotation, the water guide hole can switch between different outlet holes, allowing the water flow to change direction and achieving the valve function. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-11The diagram shows the integrated liquid flow pump valve device of this utility model, which includes a housing 2, an upper cover 1, a pumping motor assembly 3, an impeller 4, and a steering gear frame 5. The upper cover 1 is encapsulated on the top of the housing 2. The bottom surface of the housing 2 is provided with a water inlet 221. The housing 2 is cylindrical. The inner wall of the housing is divided into an upper cylinder 21 and a lower cylinder 22 in the middle. The diameter of the upper cylinder 21 is larger than the diameter of the lower cylinder 22. A supporting step 23 is provided between the upper cylinder 21 and the lower cylinder 22.

[0028] The pump motor assembly 3 is connected to the bottom surface of the upper cover 1. A fixed shaft 11 is located at the center of the pump motor assembly 3, with its top end connected to the center of the upper cover 1. The fixed shaft 11 extends downwards along the axis of the housing 2. The impeller 4 is rotatably connected to the bottom of the fixed shaft 11. The core of the bottom surface of the impeller 4 has a suction port 41 opposite to the water inlet 221. The pump motor assembly 3 drives the impeller 4 to rotate, causing the water from the water inlet 221 to enter the impeller 4 through the suction port 41 and be thrown out radially as the impeller 4 rotates. The machine component 3 includes a stator magnet 31, a stator plate 32, a permanent magnet 33, and a rotor magnet 34. The stator plate 32 is provided with the stator magnet 31 and is connected to the bottom surface of the upper cover 1. The rotor magnet 34 is provided with the permanent magnet 33. The permanent magnet 33 and the stator magnet 31 are positioned correspondingly. The rotor magnet 34 is a circular plate. The core of the rotor magnet 34 is locked to the shaft sleeve 42 of the impeller 4. When the stator plate 32 is energized, the rotor magnet 34 and the permanent magnet 33 drive the shaft sleeve 42 and the impeller 4 to rotate forward or in reverse.

[0029] The lower cylinder 22 of the housing has multiple water outlet holes 24 circumferentially arranged on its side wall. An annular rotating guide plate 6 is provided on the outer side of the impeller 4, with a gap between the rotating guide plate 6 and the impeller 4. A water guide hole 61 is provided on the rotating guide plate 6. Specifically, the lower cylinder of the housing 2 has three water outlet holes 24 on its circumferential surface, with a circumferential angle of 100-120 degrees between the water outlet holes 24. An electrical connector 12 is provided on the upper cylinder 1, through which power can be connected to the stator plate 32. The water guide hole 61 of the rotating guide plate 6 is an arc-shaped hole penetrating the side wall of the rotating guide plate 6. Multiple sealing gaskets 222 are provided between the rotating guide plate 6 and the lower cylinder 22 of the housing. Each sealing gasket 222 has a circular hole in its center for water flow. The sealing gaskets 222 are fixedly connected to the inner wall of the lower cylinder 22 of the housing, and each sealing gasket 222 corresponds to one of the water outlet holes 24.

[0030] A steering gear frame 5 is installed on the supporting step 23. A gear ring 62 is provided on the inner wall of the rotating guide plate 6. The steering gear frame 5 is connected between the rotating guide plate 6 and the impeller 4. As the rotating guide plate 6 rotates, the water guide hole 61 can switch and align between different water outlet holes 24 to transport the water in the impeller 4 in different directions.

[0031] The impeller 4 is fixedly provided with a bushing 42 at its center. The bushing 42 is rotatably connected to the outside of the fixed shaft 11. A sliding sleeve 111 is provided between the bushing 42 and the fixed shaft 11. A one-way bearing is provided on the outside of the bushing 42. The inner side of the one-way bearing is fixedly connected to the bushing 42. The outer side of the one-way bearing 43 is connected to the first gear 45 through a sleeve. The one-way bearing 43 and the first gear 45 are connected by a one-way transmission. When the one-way bearing 43 rotates forward with the bushing 42, the first gear 45 does not move. When the one-way bearing 43 rotates in reverse with the bushing 42, the first gear 45 rotates synchronously.

[0032] The steering gear frame 5 is disposed in the upper cylinder 21. The steering gear frame 5 includes a frame body 51 and multiple gears. The frame body 51 includes a lower support plate 511, an upper support plate 512, and support columns 513. The lower support plate 511 is disposed on the support step 23. The upper support plate 512 is connected to the lower support plate 511 in parallel by multiple support columns 513. A second double gear 52, a third double gear 53, a fourth double gear 54, a fifth double gear 55, and a sixth double gear 56 are sequentially arranged around the central axis inside the frame body 51. The central axis of the above five double gears is rotatably connected to the frame body 51. The first gear 45 and the second double gear... The driving gear of gear 52 meshes with the driving gear of the second double gear 52, which meshes with the driving gear of the third double gear 53. The driven gear of the third double gear 53 meshes with the driving gear of the fourth double gear 54. The driven gear of the fourth double gear 54 meshes with the driving gear of the fifth double gear 55. The driven gear of the fifth double gear 55 meshes with the driving gear of the sixth double gear 56. The central axis of the sixth double gear 56 passes downward through the lower support plate 511. The driven gear of the sixth double gear 56 meshes with the gear ring 62 on the inner wall of the rotating guide plate 6 at the bottom of the lower support plate 511. The reduction ratio between the first gear 45 and the gear ring 62 of the rotating guide plate 6 is 120-500.

[0033] The operating principle of this integrated liquid flow pump valve device is as follows: Power is supplied to the stator plate 32 via the electrical connector 12 of the upper cover 1. The stator plate 32 and stator magnet 31 drive the permanent magnet 33 and rotor magnet 34 to rotate in the forward direction. The rotor magnet 34 drives the impeller 4's bushing 42 to rotate around a fixed shaft. The impeller 4 and bushing 42 rotate simultaneously. Water flowing into the inlet 221 is pumped into the impeller from the suction port 41 at the bottom of the impeller 4. As the impeller 4 rotates in the forward direction, the water flows outward in a radial arc and exits from the guide hole 61 and its aligned outlet hole 24. The sealing gasket 222 ensures the tightness between the guide hole 61 and the outlet hole 24, preventing leakage when the water flows outward. The above process is the normal pumping function. During the forward rotation of the one-way bearing 43 driven by the bushing 42, there is no transmission between the one-way bearing 43 and the first gear 45. The first gear 45 remains stationary, and the steering gear set 5 does not work.

[0034] When it is necessary to switch the outflow direction of the water, the magnetic field of the stator plate 32 is adjusted to cause the rotor magnet 34 to rotate in the opposite direction. The rotor magnet 34 drives the bushing 42 and the impeller 4 to rotate in the opposite direction. The impeller 4 stops pumping water inward. The bushing 42 drives the one-way bearing 43 to rotate in the opposite direction. The one-way bearing 43 drives the first gear 45 to rotate. The first gear 45 drives the second double gear 52 to rotate. The second double gear 52 drives the third double gear 53 to rotate. The third double gear 53 drives the fourth double gear 54 to rotate. The fourth double gear 54 drives the fifth double gear 55 to rotate. The fifth double gear 55 drives the sixth double gear 56 to rotate. The six double gears 56 mesh with the gear ring of the rotating guide plate 6, driving the rotating guide plate 6 to rotate. Since there is a reduction ratio of 120 between the first gear 45 and the sixth double gear 56, the rotation speed of the sixth double gear 56 driving the rotating guide plate 6 is low. The low speed can improve the accuracy and stability of the alignment of the water guide hole 61 and the water outlet hole 24. During the rotation, the water guide hole 61 gradually aligns with the next water outlet hole 24. After complete alignment, the magnetic field of the stator plate 32 is switched to the normal state, the first gear 45 stops rotating, the rotating guide plate 6 also remains stationary, and the water pumped out of the impeller 4 changes direction and flows outward from the aligned water outlet hole 24.

[0035] The above descriptions are merely several preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations and substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
