Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, specifically a four-pole double-control automotive fan motor. Background Technique

[0002] With the rapid development of the automotive industry, the complexity of automotive electronic systems has been increasing day by day. Among them, the automotive fan motor, as a key heat dissipation component, plays a crucial role in ensuring the normal operation of vehicle engines and electronic components. The four-pole double-control automotive fan motor, with its characteristics of high efficiency and strong controllability, has been widely used in modern automotive designs. Such motors not only have multiple pole numbers (such as four poles) to provide finer speed control and more stable operation, but also achieve precise adjustment of the fan speed through a double-control strategy;

[0003] Chinese publicly authorized invention: CN208691070U discloses an automotive fan motor, the structure of which includes a motor, and the motor also includes a rear shell, the rear shell is arranged at the lower end of the motor and is fixedly connected to the motor; the motor is provided with a rotating shaft, a cooling fan and cooling holes, the rear shell is provided with a power connection head, a fixing block, a limiting plate, a support block and a telescopic rod, and a spring is arranged on the telescopic rod. The rotating shaft is arranged in the middle of the interior of the motor and is rotationally connected to the motor. This automotive fan motor can dissipate heat from the motor through the provided cooling fan and cooling holes, reduce the internal temperature of the motor, increase the service life of the motor, and reduce costs; through the provided spring, in cooperation with the fixing block and the support block, it can shock-absorb the motor during the operation of the motor, reduce the noise of the motor, and has great utilization value and popularization value;

[0004] However, there are still certain problems with its device. During actual use, this type of motor usually uses a combined structure of a spring, a fixing block and a support block to try to reduce the vibration and noise generated during the operation of the motor. This design plays a certain role in shock absorption to a certain extent, but limited by its limitation of only being able to achieve single-stage shock absorption, its shock absorption effect is not ideal. Since the single-stage shock absorption system is often difficult to comprehensively and effectively absorb and disperse vibration energy in the face of complex and changeable vibration environments, when the motor rotates at high speed or encounters a large impact, obvious vibration and noise will still be generated. This not only affects the riding comfort inside the vehicle, but may also have an adverse impact on the service life and performance stability of the motor. Therefore, we propose a four-pole double-control automotive fan motor to solve the above problems. Content of the Utility Model
