[0019] The utility model provides the following technical solutions:

[0020] As attached Figure 1-3 As shown, the utility model discloses a novel automotive electronic water pump housing structure which is convenient for assembling a stator assembly, comprising a housing 1, a mounting cavity 2 being formed in the housing 1, a stator assembly 3 being arranged in the mounting cavity 2, a positioning shaft 4 and a positioning boss 5 being arranged in the mounting cavity 2, the positioning shaft 4 being arranged at the axial center position of the mounting cavity 2, a positioning hole 6 corresponding to the positioning shaft 4 being provided at the center of the stator assembly 3, the positioning shaft 4 passing through the positioning hole 6 to position the stator assembly 3 in the mounting cavity 2, a plurality of positioning bosses 5 being arranged, the positioning bosses 5 being arranged at a side of the mounting cavity 2 away from the positioning shaft 4, the positioning bosses 5 supporting the stator assembly 3 in the mounting cavity 2. Specifically, in the present design, by providing a positioning shaft 4 for positioning the stator assembly 3 and a positioning boss 5 for supporting the control board 8 in the stator assembly 3 in the installation cavity 2, when installing the stator assembly 3, the user can align the central positioning hole 6 of the stator assembly 3 with the positioning shaft 4, and then insert the stator assembly 3 into the installation cavity 2, and the positioning shaft 4 will pass through the positioning hole 6 to ensure that the position of the stator assembly 3 in the installation cavity 2 is accurate, and then the positioning shaft 4 is fixed to the stator mounting seat 9 and the stator punching sheet 10 in the stator assembly 3 by positioning screws to ensure the stability and reliability of the stator assembly 3. In addition, the provision of the positioning boss 5 can effectively support the control board 8 in the stator assembly 3 to prevent it from shaking or shifting during operation, thereby improving the stability and reliability of the automotive electronic water pump.

[0021] Furthermore, a positioning screw hole 7 is provided at the top of the positioning shaft 4, and the positioning screw hole 7 is provided corresponding to the positioning hole 6 of the stator assembly 3. A positioning screw (not shown) is provided between the positioning hole 6 and the positioning screw hole 7, and the positioning screw is sequentially inserted into the positioning hole 6 and the positioning screw hole 7 to connect the stator assembly 3 and the positioning seat. Specifically, in this embodiment, by providing the positioning screw hole 7 at the top of the positioning shaft 4, during the assembly process of the stator assembly 3, the user only needs to align the positioning hole 6 of the stator assembly 3 with the positioning shaft 4, and then pass the positioning screw through the positioning hole 6 and screw it into the positioning screw hole 7, so as to achieve a tight connection between the stator assembly 3 and the positioning shaft 4. This design not only simplifies the assembly process and improves the assembly efficiency, but also ensures that the connection between the stator assembly 3 and the positioning shaft 4 is firm and reliable, and effectively prevents loosening or misalignment during the assembly process.

[0022] Further, the stator assembly 3 includes a control board 8, a stator mounting seat 9 and a stator punching sheet 10, the positioning holes 6 include a control board positioning hole 11, a mounting seat positioning hole 12 and a punching sheet positioning hole 13 which are correspondingly arranged on the control board 8, the stator mounting seat 9 and the stator punching sheet 10, the positioning shaft 4 sequentially passes through the control board positioning hole 11, the mounting seat positioning hole 12 and the punching sheet positioning hole 13 to connect with the stator assembly 3, and the positioning boss 5 supports the control board 8. Specifically, in this embodiment, the stator mounting seat 9 includes an upper mounting seat 14 and a lower mounting seat 15, a plurality of stator punching sheets 10 are arranged, and all are arranged between the upper mounting seat 14 and the lower mounting seat 15, and by respectively arranging the positioning holes 6 on the control board 8, the stator mounting seat 9 and the stator punching sheet 10, the positioning shaft 4 can sequentially pass through these positioning holes 6, thereby realizing the precise positioning and connection between the stator assembly 3 and the positioning shaft 4. At the same time, the positioning boss 5 provides effective support for the control board 8, thereby preventing the control board 8 from shaking or shifting during operation, and further improving the stability and reliability of the automotive electronic water pump.

[0023] Further, the positioning boss 5 is arranged in a two-stage structure, and the positioning boss 5 has a support portion 16 and a positioning portion 17, and the support portion 16 and the positioning portion 17 are arranged in a cylindrical structure. The positioning portion 17 is formed by protruding from the center of the top of the support portion 16, and the outer diameter of the positioning portion 17 is smaller than the outer diameter of the support portion 16. The control board 8 is installed on the positioning boss 5 through the control board positioning hole 11. Specifically, in this embodiment, the two-stage structure of the positioning boss 5 enables it to have not only a supporting function but also a positioning function. The support portion 16 is the main supporting structure, and its larger outer diameter design can provide sufficient supporting area, thereby effectively preventing the control board 8 from shaking or shifting during operation. The design of the positioning portion 17 realizes the precise positioning of the control board 8, and the control board 8 is provided with a mounting hole 19 for connecting with the positioning portion 17. The outer diameter of the positioning portion 17 is smaller than that of the support portion 16, which enables the control board positioning hole 11 to be easily sleeved on the positioning portion 17 during the assembly process, so as to realize the precise docking of the control board 8 with the positioning boss 5. This design not only simplifies the assembly process, but also improves the assembly accuracy, further enhancing the stability and reliability of the automotive electronic water pump.

[0024] Furthermore, the positioning bosses 5 are evenly spaced and distributed on the same circumference with the positioning shaft 4 as the center. Specifically, in this embodiment, the positions of the positioning bosses 5 in the mounting cavity 2 are arranged according to the mounting angle of the Hall element 18. The arrangement of this embodiment enables each positioning boss 5 to accurately correspond to the mounting position on the control board 8. This evenly spaced distribution not only ensures that the control board 8 is evenly stressed, but also improves its stability.

[0025] Furthermore, the positioning bosses 5 are distributed on different circumferences with the positioning shaft 4 as the center. Specifically, in this embodiment, the positioning bosses 5 are distributed on different circumferences. This design method can adjust the position and number of the positioning bosses 5 according to actual needs to meet the installation requirements of different models of electronic water pumps.

[0026] Furthermore, a Hall element 18 is provided on the control board 8, and the Hall element 18 senses the signal between the stator assembly and the control board 8. Specifically, in this embodiment, the Hall element 18 can accurately sense the signal between the stator and the control board 8 to ensure the normal operation of the water pump. By real-time monitoring and controlling the working state of the water pump, the Hall element 18 can promptly discover and solve potential problems, thereby ensuring the stability and reliability of the automotive electronic water pump.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
