[0053] Typical embodiments embodying the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can be varied in a wide range of embodiments, none of which depart from the scope of the present disclosure, and that the description and drawings are to be considered in an illustrative, and not restrictive, sense.

[0054] In the following description of various example embodiments of the present disclosure, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various example structures, systems, and steps in which aspects of the present disclosure can be practiced. It is understood that other specific arrangements of parts, structures, example devices, systems, and steps can be utilized and structural and functional modifications can be made without departing from the scope of the present disclosure. Also, while the terms "over," "between," "inside," "on," "under," and the like, can be used in this specification to describe relative location, such terms are placed herein merely using such directional terms simplifying the description. Any orientation of structural aspects relative to each other as described herein, including without limitation, any orientation of structural aspects described herein relative to the viewer, is intended to be encompassed within the scope of the present disclosure.

[0055] Referring to Figure 1 , a perspective view schematically shows a water pump according to the present disclosure. In this example embodiment, the water pump according to the present disclosure is described by way of example as applied to a water pump for a vehicle thermal management system. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes can be made to the specific embodiments described below without departing from the principles of the water pump according to the present disclosure.

[0056] As shown in Figure 1 , in an embodiment of the present disclosure, the water pump according to the present disclosure includes a pump housing 100 and a pump head 200. For reference, see Figures 2 to 8 , Figure 2 , a perspective exploded view schematically shows the water pump; Figure 3 , an enlarged view schematically shows a portion A in Figure 2 ; and Figure 4 , an enlarged view schematically shows a portion B in Figure 2 ; and Figure 5 , a perspective view schematically shows a spring leaf 300; Figure 6 , a perspective view schematically shows an assembled structure of the pump head 200 and the spring leaf 300; Figure 7 , an enlarged view schematically shows a portion C in Figure 6 ; and Figure 8 , a partial cross-sectional view schematically shows Figure 6 . The structure, connection, and functional relationship of the main components of the water pump according to the present disclosure will be described in detail below with reference to the above-described drawings.

[0057] As shown in Figures 1 to 7As shown, in an embodiment of the present disclosure, the water pump provided by the present disclosure further comprises a spring sheet 300. The spring sheet 300 is provided with a first buckle 320, and the pump shell 100 is provided with a first clamping groove 110, and the first buckle 320 is buckled with the first clamping groove 110. In addition, the spring sheet 300 is provided with a second buckle 330, and the pump head 200 is provided with a second clamping groove 210, and the second buckle 330 is buckled with the second clamping groove 210. In this way, the pump shell 100 and the pump head 200 can be connected through the spring sheet 300. Through the above structural design, the water pump provided by the present disclosure can realize the assembly of the pump shell 100 and the pump head 200 by using the spring sheet 300. Since the assembly mode of the inner and outer two groups of buckles is adopted, compared with the existing scheme of adopting the bolt fixing mode, the present disclosure can simplify the assembly process, improve the assembly efficiency, and reduce the number of parts, which is beneficial to reduce the overall volume and weight of the water pump.

[0058] Specifically, when the pump shell 100 and the pump head 200 need to be assembled, the spring sheet 300 can be first installed into the inner periphery of the second joint of the pump head 200, that is, the second buckle 330 is buckled with the second clamping groove 210. Then, the first joint of the pump shell 100 is inserted into the second joint of the pump head 200. Specifically, the pump shell 100 can be directly pressed into the pump head 200 by applying a torsion force to the pump shell 100. The first buckle 320 of the spring sheet 300 is extruded to deform and is buckled in the first clamping groove 110. During the assembly process, the relative positions of the first buckle 320 and the first clamping groove 110 are aligned until the first buckle 320 is buckled with the first clamping groove 110. In this way, the assembly of the pump shell 100 and the pump head 200 is completed.

[0059] It should be noted that in some other embodiments of the present disclosure, the first clamping groove can also be arranged on the spring sheet 300, and the first buckle can also be arranged on the pump shell 100. Similarly, in some other embodiments of the present disclosure, the second clamping groove can also be arranged on the spring sheet 300, and the second buckle can also be arranged on the pump head 200. In other words, in various possible embodiments consistent with the design concept of the present disclosure, one of the spring sheet 300 and the pump shell 100 is provided with the first clamping groove 110, and the other is provided with the first buckle 320, and the first buckle 320 is buckled with the first clamping groove 110. In addition, one of the spring sheet 300 and the pump head 200 is provided with the second clamping groove 210, and the other is provided with the second buckle 330, and the second buckle 330 is buckled with the second clamping groove 210.

[0060] As Figure 5As shown, in one embodiment of the present disclosure, a spring piece 300 may include a body 310, a portion of the body 310 being provided with a first latch 320 (or a first latching slot), and another portion of the body 310 being provided with a second latch 330 (or a second latching slot). Specifically, the present disclosure provides the first latch 320 and the second latch 330 on two portions of the body 310, respectively. That is, the body 310 does not use its entire area to form the two aforementioned latch structures. The two portions of the body 310, respectively formed with the first latch 320 and the second latch 330, may not overlap at all or may at least partially overlap in the circumferential direction of the spring piece 300.

[0061] like Figures 3 to 5 As shown, in one embodiment of the present disclosure, the body 310 has an inner surface 311 facing the pump housing 100 and an outer surface 312 facing the inner circumference of the pump head 200. Based on this, a first buckle 320 can be provided on the inner surface 311 of the body 310, and a first slot 110 can be provided in the pump housing 100. Furthermore, a second buckle 330 can be provided on the outer surface 312 of the body 310, and a second slot 210 can be provided in the pump head 200.

[0062] like Figure 3 and Figure 8 As shown, in one embodiment of the present disclosure, the body 310 of the spring sheet 300 can be provided with a through hole 313, which passes through the body 310 along the thickness direction. On this basis, one end of the first clip 320 is integrally connected to the hole wall of the through hole 313, and the other end of the first clip 320 is bent from the through hole 313 toward the inner surface 311 side. For example, the other end of the first clip 320 can be bent outward in a direction away from the pump head 200, so that the first clip 320 functions as a barb structure when it is engaged with the first slot 110. Through the above structural design, the present disclosure can reduce the processing difficulty of the spring sheet 300 and help reduce the weight of the components. In some embodiments, the body 310 may not be provided with a through hole 313, that is, the first clip 320 may also be directly provided on the inner surface 311 of the body 310, and the specific setting method can be one-piece molding, welding, bonding, etc., which are not limited to this embodiment.

[0063] like Figure 3 、 Figure 5 and Figure 7As shown in the embodiment of the present disclosure, the body 310 of the spring sheet 300 can be a non-closed structure, i.e., the body 310 is not a closed ring type, so that the body 310 has an end. On this basis, the second buckle 330 can be integrally bent on the side of the end of the body 310 towards the outer surface 312. Through the above structural design, the present disclosure can reduce the processing difficulty of the spring sheet 300. In some embodiments, the second buckle 330 can also be directly arranged on the outer surface 312 of the body 310, and the specific arrangement manner can be welding, bonding, etc. In addition, the body 310 of the spring sheet 300 can also be a closed structure, which is not limited to the embodiment.

On this basis, the second buckle 330 can be integrally bent on the side of the end of the body 310 towards the outer surface 312. Through the above structural design, the present disclosure can reduce the processing difficulty of the spring sheet 300. In some embodiments, the second buckle 330 can also be directly arranged on the outer surface 312 of the body 310, and the specific arrangement manner can be welding, bonding, etc. In addition, the body 310 of the spring sheet 300 can also be a closed structure, which is not limited to the embodiment.

[0066] As shown in the embodiment of the present disclosure, the body 310 of the spring sheet 300 can be a non-closed structure, i.e., the body 310 is not a closed ring type, so that the body 310 has an end.

Figures 1 to 3 As shown in the embodiment of the present disclosure, the body 310 of the spring sheet 300 can be a non-closed structure, i.e., the body 310 is not a closed ring type, so that the body 310 has an end. On this basis, the second buckle 330 can be integrally bent on the side of the end of the body 310 towards the outer surface 312. Through the above structural design, the present disclosure can reduce the processing difficulty of the spring sheet 300. In some embodiments, the second buckle 330 can also be directly arranged on the outer surface 312 of the body 310, and the specific arrangement manner can be welding, bonding, etc. In addition, the body 310 of the spring sheet 300 can also be a closed structure, which is not limited to the embodiment.

[0067] As shown in the embodiment of the present disclosure, the body 310 of the spring sheet 300 can be a non-closed structure, i.e., the body 310 is not a closed ring type, so that the body 310 has an end. On this basis, the second buckle 330 can be integrally bent on the side of the end of the body 310 towards the outer surface 312. Through the above structural design, the present disclosure can reduce the processing difficulty of the spring sheet 300. In some embodiments, the second buckle 330 can also be directly arranged on the outer surface 312 of the body 310, and the specific arrangement manner can be welding, bonding, etc. In addition, the body 310 of the spring sheet 300 can also be a closed structure, which is not limited to the embodiment. Figure 3 , Figure 7 andFigure 8 As shown, in one embodiment of the present disclosure, an annular groove 220 may be provided on the inner circumference of the interface 201 of the pump head 200, thereby allowing the body 310 of the spring piece 300 to be accommodated in the annular groove 220. On this basis, the distance between at least a portion of the first clip 320 and the bottom of the annular groove 220 is greater than the groove depth H1 of the annular groove 220. Through the above structural design, the present disclosure can utilize the annular groove 220 to accommodate the spring piece 300, thereby achieving the position limitation of the spring piece 300 along the axial direction of the pump housing 100 (i.e., the docking direction of the pump head 200 and the pump housing 100). At the same time, combined with the snap fit between the second clip 210 and the second clip 330, the present disclosure can also achieve the position limitation of the spring piece 300 along the circumferential direction, thereby ensuring the stability of the assembly positioning of the spring piece 300.

[0068] like Figure 8 As shown, in one embodiment of the present disclosure, the annular groove 220 includes a first annular surface 2201 and a second annular surface 2202 relative to each other, the length L2 of the second annular surface 2202 along the radial direction of the water pump is greater than the length L1 of the first annular surface 2201 along the radial direction of the water pump, and the pump housing 100 is partially clamped between the second annular surface 2202 and the first buckle 320.

[0069] In one embodiment of the present disclosure, the pump housing 100 includes a boss 120. One surface of the boss 120 abuts the pump head 200, and the other surface is provided with a first retaining groove 110. The distance between the boss 120 and the bottom of the annular groove 220 is greater than or equal to the depth H1 of the annular groove 220, and less than the distance between at least a portion of the first retaining clip 320 and the bottom of the annular groove 220.

[0070] like Figure 8 As shown, based on the structural design of an annular groove provided on the inner periphery of the interface 201, in one embodiment of the present disclosure, the groove depth H1 of the annular groove 220 may be equal to the thickness H2 of the body 310. In other words, the body 310 can be entirely accommodated in the annular groove 220, that is, the inner surface 311 of the body 310 is flush with the surface of the region where the annular groove 220 is provided on the inner periphery of the interface 201. Through the above-mentioned structural design, the present disclosure can achieve the connection between the outer periphery of the first joint and the inner periphery of the second joint, further improving the assembly effect of the pump housing 100 and the pump head 200. In some embodiments, the groove depth H1 of the annular groove 220 may not be equal to (for example, greater than or less than) the thickness H2 of the body 310. It is only necessary to ensure that the first buckle 320 at least partially extends out of the annular groove 220 and can be snap-fitted and assembled with the first clip 110. The present disclosure is not limited to this embodiment.

[0071] like Figure 3 As shown, in one embodiment of the present disclosure, the second engaging groove 210 is formed by the bottom of the annular groove 220 being recessed inward, and the second engaging groove 210 forms a penetrating notch 211 on one side of the annular groove 220 .

[0072] As shown in Figure 3 , Figure 5 and Figure 7 indicated, in an embodiment of the present disclosure, the water pump provided by the present disclosure can include at least two spring sheets 300, which are arranged in a circumferential direction of the pump shell 100. By means of the above structural design, taking the shapes of the pump shell 100 and the interface 201 in the circumferential direction as an example, when the spring sheet 300 is at least two, and considering the gap between the two spring sheets 300, each spring sheet 300 can be in the shape of a circular arc with a corresponding arc less than 180° (i.e., a minor arc). Accordingly, compared with the spring sheet 300 in the shape of a closed circle or a circular arc with a corresponding arc greater than 180° (i.e., a major arc), the present disclosure can further reduce the assembly difficulty of the spring sheet 300 when being assembled into the interface 201. In some embodiments, the water pump provided by the present disclosure can also include three or more spring sheets 300, and is not limited to the present embodiment.

[0073] As shown in Figure 3 , Figure 5 and Figure 7 indicated, based on the structural design that the water pump includes at least two spring sheets 300, in an embodiment of the present disclosure, the water pump provided by the present disclosure can specifically include two spring sheets 300. By means of the above structural design, on the basis of ensuring the reduction of assembly difficulty, the present disclosure can reduce the number of components.

[0074] As shown in Figure 5 indicated, based on the structural design that the water pump includes at least two spring sheets 300, in an embodiment of the present disclosure, each spring sheet 300 can be a component with the same structure. For example, when the spring sheet 300 is two, each spring sheet 300 has a corresponding arc not greater than 180°, and for example, when the spring sheet 300 is three, each spring sheet 300 has a corresponding arc not greater than 120°. By means of the above structural design, the present disclosure can reduce the structural complexity of components, which is conducive to the mass production and processing of the spring sheet 300, without the need for separate processing, and without the need to distinguish the spring sheets 300 in different positions when assembling, which is conducive to improving the assembly efficiency and avoiding misassembly.

[0075] In an embodiment of the present disclosure, the pump head 200 is provided with the water outlet 202. Along the circumference of the pump shell 100, the first buckles 320 are evenly arranged at intervals, and a is a positive integer greater than or equal to 2. The first buckling grooves 110 are evenly arranged at intervals, and b is a positive integer greater than or equal to 2. On this basis, b = N x a, where N is a positive integer greater than or equal to 1. In other words, the number of the first buckles 320 and the first buckling grooves 110 is at least two, and the number of the first buckling grooves 110 can be a multiple of the number of the first buckles 320. Accordingly, the water pump provided by the present disclosure can adjust the direction of the water outlet 202 by selectively assembling the first buckles 320 in part of the first buckling grooves 110. It should be noted that the above description of the number of the first buckles 320 refers to the sum of the number of the first buckles 320 of all the spring sheets 300. For example, Figure 5 For example, the number of the first buckles 320 is 6 (i.e., a = 6), and when the water pump includes two spring sheets 300, and both of the spring sheets 300 are structural members, each of the spring sheets 300 is provided with three first buckles 320.

[0076] Specifically, in an embodiment of the present disclosure, the number of the first buckles 320 is 6, and the number of the first buckling grooves 110 is 6. When assembling, the six first buckles 320 are respectively assembled in the six first buckling grooves 110. When it is necessary to adjust the direction of the water outlet 202, the pump shell 100 and the pump head 200 can be separated, i.e., the first buckles 320 remain assembled with the second buckling grooves 210 and are disengaged from the first buckling grooves 110, and then the pump head 200 and the pump shell 100 are relatively rotated along the axial direction, and then assembled again to adjust the direction of the water outlet 202. Since the number of the first buckles 320 and the first buckling grooves 110 is 6, the rotation angle of each relative rotation is a multiple of 360° / 6 = 60°, such as 60°, 120°, 180°, 240°, and 300°. It should be understood that the number of the first buckles 320 can be less than the number of the first buckling grooves 110, i.e., the number of the first buckling grooves 110 is twice or more than twice the number of the first buckles 320. For example, the number of the first buckling grooves 110 is still 6, and the number of the first buckles 320 can be 2 or 3, and in this case, the rotation angle of each relative rotation is still a multiple of 360° / 6 = 60°. For another example, the number of the first buckling grooves 110 is 8, and the number of the first buckles 320 can be 2, 4, or 8, and in this case, the rotation angle of each relative rotation is a multiple of 360° / 8 = 45°, such as 45°, 90°, 135°, 180°, 225°, 270°, and 315°. Accordingly, it can be known that the minimum angle of each adjustment (which can also be understood as the adjustment accuracy of the water outlet 202) when adjusting the direction of the water outlet 202 is determined by the number of the first buckling grooves 110, and the minimum angle can be 360° / b.

[0077] In an embodiment of the present disclosure, the material of the pump shell 100 can be aluminum. The material of the pump head 200 can also be aluminum. On this basis, the material of the spring sheet 300 can be stainless steel. Accordingly, since stainless steel has greater hardness than aluminum, the present disclosure can further improve the assembly effect of the spring sheet 300.

[0078] It should be noted that the water pump shown in the drawings and described in the specification is only a few examples of many kinds of water pumps that can employ the principles of the present disclosure. It should be clearly understood that the principles of the present disclosure are by no means limited to any details or any components of the water pump shown in the drawings or described in the specification.

[0079] In summary, the water pump provided by the present disclosure includes a pump shell 100, a pump head 200, and a spring sheet 300. One of the spring sheet 300 and the pump shell 100 is provided with a first clamping groove 110, and the other is provided with a first clamping buckle 320. The first clamping buckle 320 is clamped with the first clamping groove 110. One of the spring sheet 300 and the pump head 200 is provided with a second clamping groove 210, and the other is provided with a second clamping buckle 330. The second clamping buckle 330 is clamped with the second clamping groove 210. The pump shell 100 and the pump head 200 are connected via the spring sheet 300. Through the above structural design, the water pump provided by the present disclosure can realize the assembly of the pump shell 100 and the pump head 200 by using the spring sheet 300. Since the assembly method of the inner and outer two groups of clamping buckles is adopted, compared with the existing scheme of adopting the bolt fixing method, the present disclosure can simplify the assembly process, improve the assembly efficiency, and reduce the number of parts, which is conducive to reducing the overall volume and weight of the water pump.
