Description

Technical Field

[0001] This utility model relates to the field of electronic water pump technology, and in particular to an insulating frame and relay ring connection structure for a pump, and a pump. Background Technology

[0002] In existing water pumps, the stator frame and relay ring structure are generally formed by injection molding, riveting, or bolting. The relay ring is formed by integrating copper busbars connected to the three-phase windings of the motor into a ring structure. Integrating the relay ring and stator frame into a single injection mold requires consideration of demolding issues, resulting in high mold costs.

[0003] In addition, the insulating frame needs to be pre-molded and then injection molded together with the relay ring, which is a complex molding process and has high production costs.

[0004] The stator frame and relay ring are connected by riveting, which requires specialized riveting or crimping equipment and involves complex installation tools.

[0005] If the stator frame and relay ring are connected by bolts, the bolts are consumable materials, the structure between the stator frame and relay ring is complex, and the installation is time-consuming and labor-intensive. Utility Model Content

[0006] The purpose of this invention is to propose a connection structure for an insulating frame and a relay ring for a pump, as well as a pump, which can reduce the production cost of the stator frame and the relay ring, and reduce the difficulty and strength of installation.

[0007] To achieve the above objectives, this utility model provides a pump insulation frame and relay ring connection structure, comprising:

[0008] The clip is located on the insulating frame of the pump's motor;

[0009] A support portion is disposed on the end face of one end of the insulating frame;

[0010] A snap-fit ​​groove is provided in the relay ring of the pump motor. The relay ring is located at one end of the insulating frame. The snap-fit ​​can be inserted into and locked in the snap-fit ​​groove. The snap-fit ​​can be locked on the upper surface of the relay ring. The lower end face of the relay ring abuts against the support part. When the snap-fit ​​is subjected to an external horizontal force, the snap-fit ​​can disengage from the snap-fit ​​groove.

[0011] Preferably, the buckle extends axially outward from the end face of the insulating frame.

[0012] Preferably, the relay ring has a protrusion extending outward from its outer periphery, and the snap-fit ​​groove is formed in the protrusion.

[0013] Preferably, one of the relay ring and the insulating frame is provided with a positioning groove, and the other is provided with a positioning element, the positioning element cooperating with the positioning groove.

[0014] Preferably, the positioning groove is an open groove formed in the circumference of the relay ring, and the positioning member can pass through the open groove.

[0015] Preferably, the upper end face of the insulating skeleton is provided with a first winding skeleton and a second winding skeleton along the circumferential direction. The height of the first winding skeleton along the axial direction is lower than the height of the second winding skeleton. The buckle is engaged in the buckle groove, and the lower surface of the relay ring abuts against the second winding skeleton.

[0016] Preferably, the positioning member is disposed on the top surface of the second winding skeleton, and the positioning member is integrally formed with the second winding skeleton.

[0017] Preferably, the buckle is integrally formed with the first winding skeleton, and the lower part of the buckle is connected to the first winding skeleton.

[0018] A pump includes the aforementioned pump insulation frame and relay ring connection structure.

[0019] As can be seen from the above, the beneficial effects of the technical solution provided by this utility model are as follows: The connection structure between the pump insulating frame and the relay ring in this utility model achieves rapid installation and fixation by setting a buckle on the insulating frame and opening a buckle groove on the relay ring. When the buckle is inserted into the buckle groove, the lower surface of the relay ring presses against the support part. By changing the connection method between the relay ring and the insulating frame, rapid installation and disassembly are achieved. Compared with the prior art, where the relay ring and the insulating frame are integrally molded by injection molding, the separate molding of the two reduces the molding difficulty and simplifies the molding process, thereby reducing costs. Compared with the prior art, where the relay ring and the insulating frame are connected by riveting or bolting, no special tools are required for assembly, reducing installation difficulty and labor intensity, thereby reducing production costs.

[0028] like Figures 1-3 As shown, this embodiment provides an insulating frame and relay ring connection structure for a pump, which is an electronic water pump.

[0029] The pump's insulating frame and relay ring connection structure includes a snap-fit ​​11, a support portion, and a snap-fit ​​groove 21. The snap-fit ​​11 is mounted on the insulating frame 1 of the pump's motor. The support portion is located on the end face of one end of the insulating frame 1. The snap-fit ​​groove 21 is located on the relay ring 2, which is also located at one end of the insulating frame 1. The snap-fit ​​11 can be inserted into and locked in the snap-fit ​​groove 21, and it can also be locked onto the upper surface of the relay ring 2. The lower end face of the relay ring 2 presses against the support portion. When the snap-fit ​​is subjected to an external horizontal force, the snap-fit ​​11 can disengage from the snap-fit ​​groove 21.

[0030] The relay ring 2 is located at one end of the insulating frame 1, which is circular and used to wind the coil winding. The relay ring 2 is a ring-shaped component with an integrated copper busbar inside. The copper busbar contacts the coil winding wound on the insulating frame 1 to form a closed circuit.

[0031] In this embodiment, the connection structure between the pump insulation frame and the relay ring achieves rapid installation and fixation by setting a buckle 11 on the insulation frame 1 and a buckle groove 21 on the relay ring 2. When the buckle 11 is inserted into the buckle groove 21, the lower surface of the relay ring 2 presses against the support, allowing the relay ring 2 and the insulation frame 1 to be quickly installed and fixed. By changing the connection method between the relay ring 2 and the insulation frame 1, rapid installation and disassembly are achieved. Compared to the prior art, where the relay ring 2 and the insulation frame 1 are integrally molded by injection molding, the separate molding process reduces molding difficulty and simplifies the molding process, thereby reducing production costs. Compared to the prior art, where the relay ring 2 and the insulation frame 1 are connected by riveting or bolting, the assembly does not require specialized tools, reducing installation difficulty and workload, thus lowering production costs.

[0032] Preferably, the buckle 11 extends axially outward from the end face of the insulating frame 1. The buckle 11 is positioned on the end face of the insulating frame 1, which does not increase the overall circumferential structural dimensions of the insulating frame 1, resulting in a compact overall structure.

[0033] Preferably, the relay ring 2 has a protrusion 23 extending outward from its outer periphery, and a locking groove 21 is formed in the protrusion 23. This arrangement only adds the protrusion 23 to a local part of the relay ring 2 to increase the structural strength of the relay ring 2 without increasing the overall structural weight of the relay ring 2.

[0034] Preferably, one of the relay ring 2 and the insulating frame 1 has a positioning groove 22, and the other has a positioning element 14. The positioning element 14 cooperates with the positioning groove 22. Specifically, the positioning groove 22 is provided on the relay ring 2 and is located on the circumferential edge of the relay ring 2. During installation, the positioning element 14 can be inserted into the positioning groove 22 axially.

[0035] In this embodiment, the positioning groove 22 and the positioning component 14 work together to ensure that the relay ring 2 and the insulating frame 1 are accurately positioned after installation. During installation, the insulating frame and the relay ring can be quickly positioned, improving work efficiency.

[0036] Preferably, the positioning groove 22 is an open groove formed circumferentially in the relay ring 2, through which the positioning member 14 can pass. The open groove extends through the relay ring 2 along its axial direction and extends from the outer periphery of the relay ring 2 to its center, thereby allowing the positioning member 14 to pass through the open groove. During installation, the relay ring 2 approaches the positioning member 14 along its axial direction, and the positioning member 14 can move relative to it axially within the open groove. Specifically, the open groove is a U-shaped groove.

[0037] After the buckle 11 passes through the buckle groove 21 and is fastened, the buckle 11 will spring back, and the positioning member 14 can move axially relative to the insulating frame 1 through the opening groove, ensuring that after the buckle 11 springs back, the lower surface of the relay ring 2 can be tightly attached to the support.

[0038] Preferably, the upper end face of the insulating frame 1 is provided with a first winding frame 12 and a second winding frame 13 along the circumferential direction. The height of the first winding frame 12 along the axial direction is lower than the height of the second winding frame 13. The buckle 11 is engaged in the buckle groove 21, and the lower surface of the relay ring 2 abuts against the second winding frame 13. In this embodiment, the support part is the second winding frame 13.

[0039] By adjusting the axial height of the first winding frame 12 and the second winding frame 13, a gap is left between the first winding frame 12 and the lower surface of the relay ring 2, which will not cause positional interference to the relay ring 2, so that the buckle 11 can smoothly rebound when inserted into the buckle groove 21. At the same time, the lower surface of the relay ring 2 presses against the second winding frame 13, and the second winding frame 13 supports the relay ring 2.

[0040] Preferably, the second winding bobbin 13 is disposed between the two sets of first winding bobbins 12. The first winding bobbins 12 and the second winding bobbin 13 have the same shape, only their axial heights differ.

[0041] Preferably, the second winding frame 13 includes three sets, with three sets of first winding fasteners 12 spaced apart between adjacent sets of second winding frames 13. The circumferential spacing between adjacent sets of first winding frames 12 is the same as the circumferential spacing between the first winding frames 12 and the second winding frames 13.

[0042] Preferably, the positioning member 14 is disposed on the top surface of the second winding frame 13, and the positioning member 14 is integrally formed with the second winding frame 13.

[0043] The positioning component 14 is integrally formed with the second winding frame 13, reducing installation and simplifying the structure. The positioning component 14 also has a stable structure. When the buckle 11 is inserted into the buckle groove 21, the lower surface of the relay ring 2 presses against the second winding frame 13.

[0044] Preferably, the buckle 11 is integrally formed with the first winding skeleton 12, and the lower part of the buckle 11 is connected to the first winding skeleton 12, which ensures the structural strength of the buckle 11 and also ensures that the buckle 11 can undergo elastic deformation and be locked in the buckle groove 21.

[0045] Preferably, the buckle 11 and the positioning element 14 can be made of plastic or metal materials so that the buckle 11 and the positioning element 14 are elastic.

[0046] This embodiment also provides a pump, including the above-mentioned pump insulation frame and relay ring connection structure. The pump is simple to assemble, has high production efficiency, and reduces production costs.

[0047] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
