AI Technical Summary
Traditional window regulators use a single Hall sensor for their lifting motors, which poses a risk of failure and poor anti-interference performance, affecting signal accuracy and reliability.
The dual Hall effect lifter motor uses two linear Hall elements mounted on the rotor at a 90° mechanical angle offset, covering the entire cycle of the rotor magnetic poles, to output alternating square wave signals. Combined with the protection and anti-interference structure on the Hall circuit board, the signal transmission accuracy and reliability are improved.
This improves the hardware redundancy and anti-interference capability of the motor, reduces errors, and ensures reliable motor operation.

Abstract
Description
Technical Field
[0001] This utility model relates to an improved invention of a dual Hall effect lift motor, and more particularly to an improved invention of a dual Hall effect lift motor. Background Technology
[0002] Traditional window lift motors mostly use a single Hall sensor to detect the rotor position, which has the following drawbacks: 1. Failure of a single Hall sensor will cause the lift's anti-pinch function to fail; 2. Poor anti-interference performance, electromagnetic noise is prone to causing erroneous signals, affecting the accuracy of the Hall signal. Therefore, existing technologies attempt to compensate for errors through software algorithms, but cannot solve the reliability problem at the hardware level. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a dual Hall effect lift motor.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The dual Hall lift motor includes a motor body, a connector and a worm gear transmission structure, characterized in that: the rotor of the motor body is equipped with a magnetic ring, the connector is integrated with a Hall circuit board, the Hall circuit board is equipped with two linear Hall elements, and the two Hall elements are mechanically offset at 90° below the rotor magnetic ring and cover the entire cycle of the rotor magnetic poles.
[0005] Two Hall elements output alternating square wave signals.
[0006] The Hall effect circuit board is equipped with a protection structure and an anti-interference structure.
[0007] The Hall circuit board is soldered to the connector's insert, and the connector is provided with positioning posts. The Hall circuit board is provided with positioning holes, which cooperate with the positioning posts.
[0008] The magnetic ring is a planar four-stage magnetic ring press-fitted onto the rotor.
[0009] The beneficial effect of this utility model is that the improved dual Hall lift motor overcomes the defects of existing single Hall elements, such as easy failure and poor anti-interference, by using hardware redundancy and mixed signal processing, namely, the setting and output of dual Hall elements with alternating square wave signals.

[0013] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-2 The dual Hall effect lifter motor includes a motor body 1, a connector 2, and a worm gear transmission structure 3. The motor body 1 includes a rotor and a stator. The connector 2 is inserted into the motor body 1. The worm gear transmission structure 3 is connected to the motor body 1. The rotor of the motor body 1 is equipped with a magnetic ring 5. The connector 2 is integrated with a Hall circuit board 6 to ensure the installation position accuracy of the Hall elements 4. The Hall circuit board 6 is equipped with two linear Hall elements 4, and the two Hall elements 4 are mechanically offset at 90° below the rotor magnetic ring 5 and cover the entire cycle of the rotor magnetic poles.

Both the protection structure and the anti-interference structure are existing structures and will not be described in detail here.
[0016] As a further improved implementation, the Hall circuit board 6 is soldered to the insert of the connector 2, and the connector 2 is provided with a positioning post 7. The Hall circuit board 6 is provided with a positioning hole, which cooperates with the positioning post to realize the integrated and quick installation of the Hall circuit board 6 and the connector 2.
[0017] As a further improved specific implementation, the magnetic ring 5 is a planar quadrupole magnetic ring press-fitted on the rotor. As the rotor rotates, it provides magnetic induction for the Hall element 4, and its flat-fit design better adapts to the installation requirements of the Hall element 4.
