Description

Technical Field

[0001] The present application relates to the technical field of water pump devices, and in particular to an axial flux motor wet rotor water pump. Background Art

[0002] Traditional water pump systems typically include a traditional motor and a mechanically sealed water pump, with the traditional motor transmitting power to the mechanically sealed water pump via a shaft. Due to the energy loss associated with power transmission via the shaft, traditional water pump systems are inefficient. Furthermore, because the seals of mechanically sealed water pumps are susceptible to wear and tear, their lifespan is short and requires regular maintenance and replacement, traditional water pump systems also suffer from high maintenance costs. Consequently, the prior art often utilizes axial flux motor wet rotor water pump systems, which directly drive the water pump through magnetic force, reducing energy losses in traditional water pump systems and improving efficiency. Furthermore, their wet rotor design replaces traditional mechanical seals, reducing maintenance costs and improving reliability and lifespan. However, in the prior art, axial flux motor wet rotor water pump systems have a relatively large axial dimension and poor space utilization due to the relatively large number of circumferentially arranged components.

[0026] The embodiment of the present application provides an axial flux motor wet rotor water pump, such as Figures 1 to 4As shown, the axial flux motor wet rotor water pump includes:

[0027] The motor assembly 100 includes a motor housing 110, a stator assembly 120, a front shield 130, a rotor assembly 140, and a rear shield 150. The stator assembly 120 is disposed within the motor housing 110. The front shield 130 and the rear shield 150 are aligned and enclosed to form a cooling chamber 400. The rotor assembly 140 is rotatably disposed within the cooling chamber 400.

[0028] The water pump assembly 200 includes a pump casing 210 and an impeller 220. The pump casing 210 is detachably connected to the motor casing 110. The front shielding cover 130, the rear shielding cover 150 and the rotor assembly 140 are all embedded in the pump casing 210. The rear shielding cover 150 separates the pump casing 210 and the motor casing 110. The rotor assembly 140 is driven by the impeller 220 through the rotating shaft 160.

[0029] like Figure 1 As shown, in this embodiment, water pump assembly 200 serves as a functional component of an axial flux motor wet rotor water pump, while motor assembly 100 serves as its power component. The motor assembly 100 drives water pump assembly 200 to achieve medium transport. As will be appreciated, since motor assembly 100 drives water pump assembly 200 through magnetic force, it can reduce energy loss and improve efficiency. Compared to mechanical seals, wet rotors offer higher reliability, longer service life, and lower maintenance costs. Their lower friction also results in better NVH performance. Furthermore, they are particularly suitable for use in environments requiring strict leakage control.

[0030] like Figure 2 and Figure 3 As shown, for the motor assembly 100, its motor housing 110 can be configured as a cylinder, one end of which can be configured as an opening. The stator assembly 120 can be fixed within the motor housing 110, and the rotor assembly 140 can be arranged in a cooling chamber 400 enclosed by the front shield 130 and the rear shield 150. The rotor assembly 140 can be rotatably arranged within the cooling chamber 400. The front shield 130 and the rear shield 150 can be made of metal, such as stainless steel; and the front shield 130 and the rear shield 150 can both be configured as disc-shaped structures, which are arranged opposite each other and spliced together.

[0031] like Figure 2 and Figure 3As shown, for the water pump assembly 200, its pump housing 210 can be configured as a tube, and the two ends of the pump housing 210 can be respectively configured as a water pump inlet 211 and a water pump outlet 212, and a water pump chamber 213 can be provided in the middle thereof, and the water pump inlet 211 and the water pump outlet 212 are both connected to the water pump chamber 213. The impeller 220 is rotatably disposed in the water pump chamber 213. When the impeller 220 rotates, it can pump the medium from the water pump inlet 211 into the water pump chamber 213 and pump it out from the water pump outlet 212. The pump housing 210 may also have an opening on one side of the water pump chamber 213. The front shield 130, the rear shield 150, and the rotor assembly 140 may all be inserted into the pump housing 210 through the opening. The rotor assembly 140 may transmit power to the impeller 220 via the rotating shaft 160. The rotating shaft 160 may pass through the front shield 130 and connect to the impeller 220. The impeller 220 may be directly sleeved on the end of the rotating shaft 160. The rotor and the impeller 220 may both be rotationally limited with the rotating shaft 160 by structures such as connecting keys, so that the rotor assembly 140 can drive the impeller 220 to rotate synchronously via the rotating shaft 160.

[0032] like Figure 2 and Figure 3 As shown, in this embodiment, when the front shield 130, the rear shield 150 and the rotor assembly 140 are all embedded in the pump housing 210, the motor housing 110 can abut against the pump housing 210. The motor housing 110 and the pump housing 210 are detachably connected, for example, the motor housing 110 and the pump housing 210 are connected by screws. When the screws lock the motor housing 110 and the pump housing 210, the motor housing 110 and the pump housing 210 can clamp and fix the front shield 130 and the rear shield 150. At the same time, the rear shield 150 can separate the pump housing 210 from the motor housing 110. When the impeller 220 rotates driven by the rotor assembly 140 and pumps the medium into the pump housing 210, the medium can flow from the rotating shaft 160 through the position of the front shield 130 into the cooling chamber 400 to directly cool the rotor assembly 140, even if it constitutes a "wet rotor"; and the rear shield 150 can prevent the medium from further flowing into the motor housing 110.

[0033] It can be understood that the present application can fully utilize the space in the pump casing 210 except for the impeller 220 by embedding the front shield 130, the rotor assembly 140 and the rear shield 150 in the motor assembly 100 together with the impeller 220, so that only the stator assembly 120 needs to be arranged in the motor casing 110, thereby reducing the overall axial size of the axial flux motor wet rotor water pump and improving its space utilization.

[0034] Specifically, a sink 214 is provided on the side of the pump housing 210 close to the motor housing 110, a first flange 131 is provided on the front shielding cover 130, and a second flange 151 is provided on the rear shielding cover 150. The second flange 151 abuts against the first flange 131, and the first flange 131 abuts against the sink 214.

[0035] like Figure 2 and Figure 4 As shown, in this embodiment, for example, the outer edge of the front shielding cover 130 can be set as a two-stage continuous step-like structure, and the first flange 131 can be a one-stage step-like structure close to the rear shielding cover 150. The shape of the pump housing 210 at the opening of the water pump chamber 213 is adapted to the shape of the outer edge of the front shielding cover 130, and a sink 214 is formed for the first flange 131 to abut. A second flange 151 can be provided on the rear shielding cover 150, the size of the second flange 151 is adapted to the first flange 131, and the second flange 151 abuts against the first flange 131. When the motor housing 110 is locked and fixed with the pump housing 210, the motor housing 110 can press and fix both the second flange 151 and the first flange 131 on the sink 214 to fix the front shielding cover 130 and the rear shielding cover 150.

[0036] It can be understood that this embodiment provides a sink 214 on the pump casing 210, a first flange 131 on the front shielding cover 130, and a second flange 151 on the rear shielding cover 150, so as to facilitate embedding the front shielding cover 130, the rear shielding cover 150 and the rotor assembly 140 arranged in the front shielding cover 130 and the rear shielding cover 150 into the pump casing 210 and to facilitate fixing them.

[0037] More specifically, a sealing gasket 500 is disposed between the first flange 131 and the sink 214 .

[0038] like Figure 2 and Figure 4 As shown, in this embodiment, the sealing gasket 500 can be made of rubber, silicone, asbestos, etc., and can be provided in an annular shape, and its size can be adapted to the first flange 131. The sealing gasket 500 can be arranged between the first flange 131 and the sinking platform 214. When the first flange 131 abuts the sinking platform 214, it squeezes the sealing gasket 500, and the sealing gasket 500 can improve the airtight effect between the first flange 131 and the sinking platform 214.

[0039] It is understandable that in this embodiment, the sealing gasket 500 is provided to increase the airtightness between the first flange 131 and the sink 214 , thereby preventing leakage of the medium when it is pumped into the pump housing 210 .

[0040] Specifically, a first bearing chamber 132 is provided on the front shielding cover 130, a first bearing member 133 is provided in the first bearing chamber 132, a second bearing chamber 152 is provided on the rear shielding cover 150, a second bearing member 153 is provided in the second bearing chamber 152, and the rotating shaft 160 is rotatably provided in the first bearing member 133 and the second bearing member 153.

[0041] like Figure 4 As shown, in this embodiment, the first bearing chamber 132 and the second bearing chamber 152 can be respectively arranged in the middle position of the front shield 130 and the rear shield 150, and can be respectively integrally formed with the front shield 130 and the rear shield 150. The first bearing chamber 132 can be set as a structure with both ends open, so that the rotating shaft 160 can pass through the front shield 130 and connect with the impeller 220. The second bearing chamber 152 can be opened only on one side close to the front shield 130 to prevent the medium from flowing into the motor housing 110. The first bearing chamber 132 and the second bearing chamber 152 can be used to respectively arrange the first bearing member 133 and the second bearing member 153. The first bearing member 133 and the second bearing member 153 can be set to the same structure and size to improve their versatility and convenience. The rotating shaft 160 is inserted into the first bearing member 133 and the second bearing member 153 so as to be rotatable.

[0042] It can be understood that this embodiment reduces the friction resistance of the rotating shaft 160 during rotation by respectively providing the first bearing chamber 132 and the second bearing chamber 152 on the front shielding cover 130 and the rear shielding cover 150, and arranging the first bearing member 133 and the second bearing member 153 in the first bearing chamber 132 and the second bearing chamber 152, so as to make the rotation of the rotating shaft 160 smoother, thereby effectively driving the impeller 220.

[0043] More specifically, the rotor assembly 140 includes a rotor support 141 and a permanent magnet 142 , which is disposed within the rotor support 141 .

[0044] like Figure 4 As shown, in this embodiment, for example, the rotor assembly 140 may include a rotor support 141 and permanent magnets 142. The rotor support 141 may be configured as an annular disc structure to further reduce its axial dimension, and may be sleeved on the rotating shaft 160. The permanent magnets 142 may be provided in pairs to form a desired magnetic field. The permanent magnets 142 may be configured as thin, arc-shaped structures disposed within the rotor support 141, and the pairs of permanent magnets 142 may be equally spaced along the circumference of the rotor support 141.

[0045] It can be understood that, in this embodiment, by rationally arranging the structure of the rotor assembly 140 , it is convenient to realize the function of the motor assembly 100 driving the water pump assembly 200 through magnetic force.

[0046] More specifically, the first bearing chamber 132 is at least partially embedded in the rotor support 141 .

[0047] like Figure 4 As shown, in this embodiment, for example, the first bearing chamber 132 can be provided on the inner side of the front shielding cover 130 and can be provided as a circular chamber. The first bearing member 133 can be assembled into the first bearing chamber 132 from the inner side of the front shielding cover 130 toward the outer side of the front shielding cover 130. The first bearing chamber 132 can be embedded in a side of the rotor support 141 close to the front shielding cover 130. The rotor support 141 can be provided with a corresponding relief structure at this location for accommodating the first bearing chamber 132.

[0048] It is understandable that, by embedding the first bearing chamber 132 into the rotor bracket 141 , this embodiment can further reduce the overall axial dimensions of the front shield 130 and the rotor assembly 140 , thereby further improving the overall space utilization of the axial flux motor wet rotor water pump.

[0049] Specifically, the stator assembly 120 includes a stator core 121 and a stator winding 122 , and the stator winding 122 is wound on the stator core 121 .

[0050] like Figure 3 and Figure 4 As shown, in this embodiment, for example, the stator assembly 120 may include a stator core 121 and a stator winding 122. The rotor bracket 141 may be made of a metal material, fixed within the motor housing 110, and its end adjacent to the rear shield 150 may abut against the rear shield 150. The stator winding 122 may be wound from a wire and wound around the stator core 121. The stator winding 122 may be wound appropriately according to the actual circuit layout requirements and is not limited here.

[0051] It can be understood that this embodiment also facilitates the function of the motor assembly 100 driving the water pump assembly 200 through magnetic force by reasonably arranging the structure of the stator assembly 120.

[0052] More specifically, the stator core 121 includes a disc-shaped member 123 and a columnar member 124 . The columnar members 124 are arranged at a circumferential interval. The disc-shaped member 123 is arranged at one end of the columnar members 124 . The end of the columnar members 124 away from the disc-shaped member 123 is plugged into the rear shielding cover 150 .

[0053] like Figure 3and Figure 4 As shown, in this embodiment, for example, the stator core 121 may include a disc 123 and a columnar 124. The disc 123 may be configured as an annular disc structure, and the columnar 124 may be provided in a plurality, and the plurality of columnar 124 may be arranged at equal intervals along the circumference of the disc 123. One end of each of the plurality of columnar 124 is connected to one side of the disc 123 to form an integral structure. The other ends of the plurality of columnar 124 abut against the rear shield 150 and are plugged into the rear shield 150. Correspondingly, the rear shield 150 may be provided with a slot structure for the columnar 124 to be plugged into.

[0054] It can be understood that this embodiment, by reasonably arranging the structure of the stator core 121 and plugging the several columnar members 124 of the stator core 121 with the rear shield cover 150, not only facilitates fixing and limiting the stator core 121 so that the stator assembly 120 is not easy to shake or deflect; it can also further reduce the overall axial size of the stator core 121 and the rear shield cover 150, and the structure is more compact.

[0055] More specifically, the second bearing chamber 152 is disposed at the center of the plurality of columnar members 124 circumferentially distributed, and the second bearing chamber 152 is at least partially embedded in the inner side of the plurality of columnar members 124 .

[0056] like Figure 4 As shown, in this embodiment, by way of example, the second bearing chamber 152 can be provided on a side of the rear shield 150 close to the stator assembly 120. It can be formed by a recess in the middle of the rear shield 150 in a direction close to the stator assembly 120. The second bearing chamber 152 can be recessed and embedded within the inner sides of the plurality of columnar members 124. In this case, the second bearing chamber 152 is located at the circumferentially distributed center of the plurality of columnar members 124. The second bearing chamber 152 can also be provided as a circular cavity, and the second bearing member 153 can be assembled into the second bearing chamber 152 from the rear shield 150 in a direction close to the stator assembly 120.

[0057] It is understandable that, by embedding the second bearing chamber 152 into a plurality of columnar members 124 , this embodiment can further reduce the overall axial dimensions of the rear shield 150 and the stator assembly 120 , thereby further improving the overall space utilization of the axial flux motor wet rotor water pump.

[0058] Specifically, the axial flux motor wet rotor water pump further includes a motor controller 300 , which is connected to an end of the motor housing 110 away from the pump housing 210 .

[0059] like Figure 1 and Figure 2As shown, in this embodiment, for example, the motor controller 300 can be integrated with the motor housing 110, and can be arranged at one end of the motor housing 110 away from the pump housing 210. The stand-alone controller can include an electronic control housing 310, an end cover 320, and an electronic control component, wherein the electronic control housing 310 can be set as a flat structure, which can be integrally formed with the motor housing 110 and can be set as an opening at one end away from the motor housing 110. The end cover 320 can cover the open end of the electronic control housing 310 and can be detachably connected to the electronic control housing 310, such as by snap-fitting or connecting through screws. The electronic control component can be arranged in the electronic control housing 310 to perform corresponding control on the motor assembly 100.

[0060] It can be understood that, in this embodiment, by integrating the motor controller 300 with the motor housing 110 , it is convenient to arrange the motor controller 300 to realize corresponding control functions.

[0061] The implementation principle of an axial flux motor wet rotor water pump provided in the embodiment of the present application is:

[0062] During assembly, the stator winding 122 is wound around the stator core 121 to form the stator assembly 120. Subsequently, the stator assembly 120 is placed within the motor housing 110. Simultaneously, the permanent magnets 142 are placed within the rotor bracket 141 to form the rotor assembly 140. The rotor assembly 140 is then sleeved onto the rotating shaft 160, and the first and second bearing members 133, 153 are placed within the first bearing chamber 132 of the front shield 130 and the second bearing chamber 152 of the rear shield 150, respectively. The rotating shaft 160 is then inserted into the first and second bearing members 133, 153, and the rotor assembly 140 is placed within the cooling chamber 400 enclosed by the front and rear shields 130, 150. The impeller 220 is then sleeved onto the rotating shaft 160, and the sealing gasket 500 is placed on the sink 214. The impeller 220, along with the front shield 130, rear shield 150, and rotor assembly 140, is then placed within the pump housing 210, with the first flange 131 of the front shield 130 abutting against the sealing gasket 500. The motor housing 110 is then connected to the pump housing 210 via screws, with the motor housing 110 pressing the front shield 130 and rear shield 150 against the sink 214. The electronic control assembly is then placed within the electronic control housing 310, and the end cover 320 is then connected to the electronic control housing 310.

[0063] The present application embeds the front shield 130, rotor assembly 140 and rear shield 150 of the motor assembly 100 together with the impeller 220 in the pump casing 210, thereby making full use of the space in the pump casing 210 except for the space occupied by the impeller 220, so that only the stator assembly 120 needs to be arranged in the motor casing 110, thereby reducing the overall axial size of the axial flux motor wet rotor water pump and improving its space utilization.

[0064] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
