Description

Technical Field

[0001] This utility model relates to an improved invention of a dual Hall effect lift motor circuit, and more particularly to an improved invention of a dual Hall effect lift motor circuit. 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 lift motor circuit to support the arrangement of dual Hall sensors.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The dual Hall effect lift motor circuit is characterized by including a power supply interface VCC, a ground interface GND, Hall elements Q1 and Q2, an output interface S1 and an output interface S2. The VCC terminals of Hall elements Q1 and Q2 are connected to the power supply interface VCC via a first line, the GND terminals of Hall elements Q1 and Q2 are connected to the ground interface GND via a second line, the output terminal of Hall element Q1 is connected to the output interface S1 via a third line, and the output terminal of Hall element Q2 is connected to the output interface S2 via a fourth line.

[0005] A Zener diode ZD3 is connected between the first line and the second line, a Zener diode ZD1 is connected between the third line and the second line, and a Zener diode ZD2 is connected between the fourth line and the second line.

[0006] A capacitor C1 is connected between the first line and the second line.

[0007] Resistors R3, R1, and R2 are connected in series on the first, third, and fourth lines, respectively.

[0008] A unidirectional diode D is connected in series on the first line.

[0009] The beneficial effect of this utility model is that the improved dual Hall lift motor circuit uses dual Hall sensors that cooperate with each other to sense the rotor magnetic ring to output alternating square wave signals, overcoming the defects of existing single Hall elements that are prone to failure and have poor anti-interference.

[0012] 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 The dual Hall effect lift motor circuit includes a power supply interface VCC, a ground interface GND, Hall elements Q1 and Q2, an output interface S1, and an output interface S2. The VCC terminals of Hall elements Q1 and Q2 are connected to the power supply interface VCC via a first line 1. The GND terminals of Hall elements Q1 and Q2 are connected to the ground interface GND via a second line 2. The output terminal of Hall element Q1 is connected to the output interface S1 via a third line 3, and the output terminal of Hall element Q2 is connected to the output interface S2 via a fourth line 4.

[0013] This circuit diagram uses dual Hall effect sensors that work together to sense the rotor magnetic ring and output alternating square wave signals. The corresponding Hall element Q1 and Hall element Q2 output signals through output interfaces S1 and S2, respectively.

[0014] As a further improved implementation, a Zener diode ZD3 is connected between the first line 1 and the second line 2 to ensure stable power supply voltage input; a Zener diode ZD1 is connected between the third line 3 and the second line 2 to ensure stable Hall signal S1 output; and a Zener diode ZD2 is connected between the fourth line 4 and the second line 2 to ensure stable Hall signal S2 output.

[0015] As a further improved implementation, a capacitor C1 is connected between the first line 1 and the second line 2 to serve as a filter and to suppress interference.

[0016] As a further improved implementation, resistors R3, R1, and R2 are connected in series on the first line 1, the third line 3, and the fourth line 4, respectively, to prevent excessive current in the circuit and avoid damage to the Hall element due to excessive current, thus protecting the circuit.

[0017] As a further improvement, a unidirectional diode D is connected in series on the first line 1, which can limit the voltage and prevent reverse current from damaging the Hall sensor.
