Description

Technical Field

[0001] The utility model relates to the technical field of motors, and more specifically to a stator seat structure and a water pumping motor using the same. Background Art

[0002] During the operation of the mobile air conditioner, the evaporator will produce condensed water, which needs to be collected and disposed of in time to avoid affecting the normal operation of the air conditioner. At present, mobile air conditioners usually use a water pumping device to treat the condensed water. The water pumping device is mainly composed of a water pumping motor and a water pumping wheel. The water pumping motor drives the water pumping flywheel to rotate, and the condensed water collected in the water receiving tray is pumped to the double-row condenser to exchange heat with the condenser. The condensed water absorbs heat and evaporates.

[0003] As the main component of the water pumping device, the stator of the water pumping motor includes an iron core plastic-coated component, a PCB board and a stator seat. The stator seat is provided with a wire outlet hole for the power line of the PCB board to pass through. When assembling the existing water pumping motor, it is necessary to assemble the iron core plastic-coated component and the PCB board and then pass the power line through the wire outlet hole. Due to the small size of the wire outlet hole, the threading process requires a certain amount of time and energy, and is highly dependent on manual labor, resulting in a relatively low assembly efficiency during the production process of the water pumping motor, thereby affecting the production efficiency of the water pumping motor. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and provide a stator seat structure that can facilitate the assembly of the power cord and solve the problem of low assembly efficiency caused by the existing power cord threading process, thereby improving production efficiency. At the same time, the utility model also provides a water pumping motor with high assembly efficiency and strong structural stability.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a stator seat structure, characterized in that: it includes a stator seat and a wire pressing block; a notch is opened on the side wall of the stator seat, and a joining module is arranged below the notch; the wire pressing block can be detachably installed on the notch, and the wire pressing block and the joining module can be detachably connected; the joining module is provided with a groove; when the wire pressing block is arranged in the notch and connected to the joining module, the area between the wire pressing block and the groove serves as a wire outlet station for the power line.

[0006] In the above scheme, since the notch of the utility model is directly opened on the upper edge of the stator seat, there is no restriction on the assembly of the power cord. In the assembly process of the water pumping motor of the utility model, the power cord directly passes through the notch, and then the wire pressing block is installed on the notch and connected to the joint module. The wire pressing block can press the power cord into the groove to position the power cord at the outlet position. The utility model does not need to be restricted by the notch when assembling the power cord. It directly passes through the notch and then positions the power cord through the wire pressing block, thereby improving the convenience of power cord assembly, solving the problem of low assembly efficiency caused by the existing power cord threading process, and improving the production efficiency of the water pumping motor.

[0007] When the wire pressing block is installed in the notch, the wire pressing block is connected with the side walls of the stator seat on both sides of the notch by transition fit.

[0008] Guide columns are arranged on both sides of the wire pressing block, and guide grooves are arranged on the side walls of the stator seat on both sides of the notch; the wire pressing block is slidably installed in the notch through the guide columns and the guide grooves, so as to realize transitional fitting connection between the wire pressing block and the side walls of the stator seat on both sides of the notch. The utility model adopts the structure of guide grooves and guide columns to improve the quick and convenient positioning installation of the wire pressing block and the side walls of the stator seat on both sides of the notch, and also ensures that the positions of the two are accurate after installation.

[0009] The detachable connection between the wire pressing block and the joining module means that the wire pressing block and the joining module are snap-fitted and connected.

[0010] The bottom of the wire pressing block is provided with a fixing hole, and the joining module is provided with a fixing column; the wire pressing block is engaged and connected with the fixing column through the fixing hole to achieve a detachable connection with the joining module.

[0011] The groove is opened on the upper end surface of the joining module; when the wire pressing block is arranged in the notch and connected to the joining module, the bottom surface of the wire pressing block and the inner side wall of the groove position the power line.

[0012] A water pumping motor, characterized in that: it includes the above-mentioned stator seat structure; the water pumping motor also includes an iron core plastic-coated component and a PCB board with a power line; the stator seat is provided with a mounting column with a hollow structure; a through hole is provided in the middle of the iron core plastic-coated component, a radial positioning portion radially positioned with the through hole is provided on the surface of the mounting column of the stator seat, and an axial positioning portion axially positioned with the iron core plastic-coated component is also provided on the surface of the mounting column of the stator seat; the iron core plastic-coated component is sleeved with the mounting column, and the stator seat is positioned and installed with the iron core plastic-coated component through the radial positioning portion and the axial positioning portion;

[0013] The PCB board is sleeved with a mounting column and is located between the iron core plastic-coated component and the stator seat. The power line of the PCB board is assembled and output through the notch. When the wire pressing block is installed in the notch and connected to the joining module, the power line is positioned at the output position.

[0014] In the above scheme, the radial positioning part and the axial positioning part of the mounting column of the stator seat of the utility model can position the iron core plastic-coated component to achieve positioning installation, so that the stator seat and the iron core plastic-coated component have a good bonding effect and accurate positioning, thereby improving the structural stability of the water pumping motor and the working performance of the water pumping motor. In addition, the power line of the PCB board can also be quickly assembled through the notch and the wire pressing block.

[0015] The radial positioning portion and the axial positioning portion are both convex portions of the mounting column protruding outward, and the radial positioning portion and the axial positioning portion are alternately distributed on the outer surface of the mounting column;

[0016] When the stator seat and the iron core plastic-coated component are positioned and installed, the radial positioning portion cooperates with the hole wall of the through hole of the iron core plastic-coated component for radial positioning;

[0017] The height of the axial positioning portion is smaller than the height of the mounting column; when the stator seat and the iron core plastic-coated assembly are positioned and installed, the axial positioning portion cooperates with the end of the iron core plastic-coated assembly for axial positioning.

[0018] The radial positioning part and the axial positioning part of the utility model adopt a disconnected structure rather than a continuous structure, which can avoid the problem of low positioning accuracy of the stator seat and the iron core plastic-coated assembly caused by shrinkage deformation during the injection molding of the plastic parts, thereby improving the stability of the installation.

[0019] The through hole wall of the core plastic-coated component is provided with a concave hole; the surface of the mounting column of the stator seat is also provided with at least one positioning column for positioning with the rotation direction of the core plastic-coated component; the positioning column is positioned and engaged with the concave hole; the positioning column is arranged on the radial positioning part. The design of the positioning column can not only be positioned with the rotation direction of the core plastic-coated component, but also can be used as an identification of the installation direction, so as to facilitate the installation of the core plastic-coated component and the stator seat.

[0020] The water pumping motor also includes a bearing; the inner wall of the mounting column is provided with a support bar for supporting the bearing; two bearings are respectively provided at the end faces of the support bar. Compared with the support surface of the full-circle structure, the design of the support bar forming the support surface can effectively reduce the matching requirements between the bearing and the support surface, avoid the problem of low positioning accuracy of the stator seat and the bearing caused by shrinkage deformation of the plastic parts during the injection molding process, and further improve the stability of the installation of the water pumping motor.
