Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0020] Please refer to Figure 1The utility model provides a technical scheme: a kind of stator structure for automobile window motor, including casing 1, the inner wall of the casing 1 is fixedly connected with magnetic tile 2, the bottom end in the casing 1 is equipped with support spring 3, the top end of the support spring 3 is connected with the lateral wall of magnetic tile 2, the bottom end of the casing 1 is fixedly provided with base 6, ball bearing 4 is installed in the base 6, the bottom end of the ball bearing 4 is provided with transition sleeve component 5.

[0021] Specific implementation, when window motor is energized and starts, current flows into the winding in stator assembly, winding will produce alternating magnetic field under the condition of energization, magnetic tile 2 in the casing 1 interacts with the alternating magnetic field, since magnetic tile 2 is fixed in the specific position of casing 1 inner wall, so that magnetic field distribution presents stable and efficient form, provides strong and uniform driving force for motor rotor rotation.

[0022] Referring to Figure 2 And Figure 4 , the outer circular arc surface of the casing 1 is provided with arc groove 7, the same position is equipped with boss 8 in the casing 1 arc inner wall, and is provided with one square recess 10.

[0023] Specific implementation, the arc groove 7 of the outer surface of casing 1, if connected with buffer or auxiliary stability when motor is running, can absorb and disperse the vibration energy generated by motor due to high-speed rotation, rotor imbalance and other factors, at the same time, the assembly transition sleeve groove 9 of the bottom of casing 1 stably fixes transition sleeve component 5, transition sleeve component 5 optimizes power transmission, ensures that motor power is stably output to subsequent transmission mechanism, realizes the stable lifting of vehicle window.

[0024] Referring to Figure 2 , the aperture of the casing 1 is fixedly connected with two symmetrical top plates 12, and two center symmetrical screw holes 11 are arranged on the two top plates 12.

[0025] Specific implementation, the aperture of the casing 1 is fixedly connected with two symmetrical top plates 12, and two center symmetrical screw holes 11 are arranged on the two top plates 12.

[0026] Referring to Figure 2 And Figure 4 , the casing 1 is adapted with brush holder assembly, and the aperture of the casing 1 is slightly larger than the diameter of the brush holder.

[0027] Specific implementation, the aperture of the casing 1 is slightly larger than the diameter of the brush holder, so that the brush holder can rotate flexibly, reduce the friction resistance between the brush holder and the inner wall of the casing 1, and reduce the heat and wear caused by friction.

[0028] Referring to Figure 3 , the casing 1 is made of zinc-magnesium-aluminum material.

[0029] In specific implementation, the shell 1 of the zinc-magnesium-aluminum material has good heat conductivity and the surface plating paint helps to optimize heat dissipation, so that the heat generated during the operation of the motor can be dissipated in time to prevent the motor from overheating.

[0030] Referring to Figure 3 , the surface of the shell 1 is plated with paint.

[0031] In specific implementation, the surface plating treatment of the shell 1 not only can further enhance the corrosion resistance of the shell 1, but also can beautify the appearance.

[0032] Working principle: when the window motor is powered on, the current flows into the winding in the stator assembly, and the winding generates an alternating magnetic field under the power. The magnetic shoe 2 in the shell 1 interacts with the alternating magnetic field. Since the magnetic shoe 2 is precisely limited by the boss 8 on the inner arc wall, the magnetic field distribution presents a stable and efficient form, providing strong and uniform driving force for the rotation of the motor rotor.

[0033] The arc-shaped groove 7 on the outer arc surface of the shell 1 can absorb and disperse the vibration energy generated by the motor due to high-speed rotation, rotor imbalance and other factors when the motor is running, prevent the vibration from being conducted to the vehicle body in a large area, thereby reducing the noise in the vehicle. At the same time, the assembly transition sleeve groove 9 at the bottom of the shell 1 stably fixes the transition sleeve component 5. The transition sleeve component 5 optimizes power transmission and ensures that the motor power is stably output to the subsequent transmission mechanism, realizing the stable lifting of the vehicle window.

[0034] The screw hole 11 provided on the shell 1 can be firmly connected to other components, maintain the closed environment in the motor, prevent dust, water vapor and other impurities from entering and affecting the performance of the motor, ensure that the internal magnetic field and electrical connection are not disturbed by the outside world, and ensure that the motor can operate reliably under complex automobile working conditions.

[0035] The shell 1 hole diameter slightly larger than the brush holder diameter allows the brush holder to rotate flexibly. On the one hand, the electric brush on the brush holder is in close contact with the rotor commutator to ensure stable current introduction into the rotor winding and maintain continuous rotation of the motor. On the other hand, the appropriate gap opens a channel for motor heat dissipation airflow, which, together with the good heat conductivity of the shell 1 material and the auxiliary optimization of the surface plating paint for heat dissipation, dissipates the heat generated during the operation of the motor in time to prevent the motor from overheating, thereby ensuring that the entire window motor works stably for a long time and responds to the window lifting command at any time.
