[0057] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0058] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0059] During the trial production of vehicles, especially in the environment of multi-variety and small-batch trial production workshops, production often faces the needs of high customization and rapid model change. In the context of multi-variety and small-batch automobile trial production workshops, it is necessary to debug the door glass lifting function of various models. The lifting and lowering of the door glass is driven by the motor inside the door. The forward or reverse rotation of the motor drives the glass up or down accordingly. Since the vehicle is not powered on during the test, the production personnel need to connect the test fixture to the door motor and conduct the test manually.

[0060] In the related art, temporary, non-standard and crude tooling is used for testing, such as connecting wires to DC power sources from different sources (such as batteries), and manually adjusting the polarity of the wires to control the forward and reverse rotation of the motor. This solution has the following disadvantages: the battery needs to be reinserted to control the motor reversal, and the battery needs to be repeatedly removed; the wires of the vehicle seat are difficult to insert into the battery; the control is not sensitive; and the staff needs to hold the tooling for a long time.

[0061] Figure 1 FIG. 1 is a schematic diagram of a motor forward and reverse control circuit according to an exemplary embodiment. Figure 1 As shown, the motor forward and reverse control circuit 100 includes a switching circuit first relay 11, a second relay 12 and a switching circuit 13.

[0062] The first end 11a of the first relay 11 is connected to the first output end of the switching circuit 13, the second end 11b of the first relay 11 is connected to the third output end of the switching circuit 13, the third end 11c of the first relay 11 is connected to the positive electrode of the DC power supply, the fourth end 11d of the first relay 11 is connected to the first end of the motor, and the fifth end 11e of the first relay 11 is connected to the negative electrode of the DC power supply.

[0063] The first end 12a of the second relay 12 is connected to the second output end of the switching circuit 13, the second end 12b of the second relay 12 is connected to the fourth output end of the switching circuit 13, the third end 12c of the second relay 12 is connected to the positive electrode of the DC power supply, the fourth end 12d of the second relay 12 is connected to the other end of the motor, and the fifth end 12e of the second relay is connected to the negative electrode of the DC power supply.

[0064] The switching circuit 13 is used to connect the third terminal 11c and the fourth terminal 11d of the first relay 11, and simultaneously connect the fourth terminal 12d and the fifth terminal 12e of the second relay 12, so that the motor enters the forward rotation mode, or to connect the fifth terminal 11e and the fourth terminal 11d of the first relay 11, and simultaneously connect the fourth terminal 12d and the third terminal 12c of the second relay 12, so that the motor enters the reverse rotation mode.

[0065] The motor includes a forward mode and a reverse mode. The operation mode of the motor is related to the power polarity of the first end and the second end of the motor. When the first relay 11 is not powered on, the third end 11c and the fourth end 11d of the first relay 11 are turned on, and the first end of the motor is connected to the positive pole of the DC power supply; when the first relay 11 is powered on, the fourth end 11d and the fifth end 11e of the first relay 11 are turned on, and the first end of the motor is connected to the negative pole of the DC power supply. When the second relay 12 is not powered on, the third end 12c and the fourth end 12d of the second relay 12 are turned on, and the second end of the motor is connected to the positive pole of the DC power supply; when the second relay 12 is powered on, the fourth end 12d and the fifth end 12e of the second relay 12 are connected, and the second end of the motor is connected to the negative pole of the DC power supply.

[0066] Thus, by controlling the conduction state of the first relay 11 and the second relay 12, the power polarity of the first end and the second end of the motor can be controlled, thereby controlling the operation mode of the motor. The switching circuit 13 may, for example, include a plurality of switches, and by controlling the conduction and disconnection of the plurality of switches, the conduction state of the first relay 11 and the second relay 12 is controlled, thereby switching the operation mode of the motor.

[0067] When the switching circuit 13 turns on the third end 11c and the fourth end 11d of the first relay 11, and turns on the fourth end 12d and the fifth end 12e of the second relay 12, the first end of the motor is connected to the positive electrode of the DC power supply, the second end of the motor is connected to the negative electrode of the DC power supply, and the motor rotates forward.

[0068] When the switching circuit 13 turns on the fifth end 11e and the fourth end 11d of the first relay 11, and turns on the fourth end 12d and the third end 12c of the second relay 12, the first end of the motor is connected to the negative pole of the DC power supply, the second end of the motor is connected to the positive pole of the DC power supply, and the motor reverses.

[0069] Through the above technical solution. The motor forward and reverse control circuit includes a first relay, a second relay and a switching circuit. Through the above connection method, in this solution, the switching circuit switches the power polarity at both ends of the motor by controlling the different conduction states of the two relays respectively, thereby controlling the forward and reverse mode of the switching motor. In this way, during the test, the production personnel do not need to manually change the power supply and wiring to switch the working mode of the motor, which improves the test efficiency and has higher safety.

[0070] Figure 2 FIG. 1 is a schematic diagram of a motor forward and reverse control circuit according to another exemplary embodiment. Figure 2 As shown, the switching circuit 13 includes a first photocoupler 1 , a second photocoupler 4 , a third photocoupler 7 and a fourth photocoupler 8 .

[0071] The fourth end 1d of the first photocoupler 1 is the first output end of the switching circuit 13, the fourth end 4d of the second photocoupler 4 is the second output end of the switching circuit 13, the third end 7c of the third photocoupler 7 is the third output end of the switching circuit 13, and the third end 8c of the fourth photocoupler 8 is the fourth output end of the switching circuit 13.

[0072] The photocoupler consists of three parts: light emission, light reception and signal amplification. The input electrical signal drives the light emitting diode (LED) to emit light of a certain wavelength, which is received by the photodetector to generate photocurrent, and then output after further amplification. The first photocoupler 11 has different high and low levels of output when it is turned on and off. The second photocoupler 2, the third photocoupler 7 and the fourth photocoupler 8 are similar to the first photocoupler 1.

[0073] In this embodiment, by setting the first photocoupler, the second photocoupler, the third photocoupler and the fourth photocoupler in the motor forward and reverse control circuit, the load circuit can be effectively isolated while transmitting the electrical signal, thereby improving the electrical insulation capacity and anti-interference ability of the motor forward and reverse circuit.

[0075] The first end 4a of the second photocoupler 4 and the third end 4c of the second photocoupler 4 are connected to the power supply through the fourth resistor 17 and the fifth resistor 18 respectively, and the second end 4b of the second photocoupler 4 is connected to the first end 6a of the second terminal 6 through the sixth resistor 19 and the second switch 5;

[0076] Among them, the first switch 2 and the second switch 5 are normally open switches.

[0077] The first switch 2 is a normally open switch. When the first switch 2 is opened, the second terminal 1b of the first photoelectric coupler 1 is at a low level, the third terminal 1c and the fourth terminal 1d of the first photoelectric coupler 1 are connected, and the fourth terminal 1d of the first photoelectric coupler 1 outputs a high level. When the first switch 2 is closed, the second terminal 1b of the first photoelectric coupler 1 is at a high level, the third terminal 1c and the fourth terminal 1d of the first photoelectric coupler 1 are disconnected, and the fourth terminal 1d of the first photoelectric coupler 1 outputs a low level.

[0078] The second switch 5 is a normally open switch. When the second switch 5 is disconnected, the second end 4b of the second photoelectric coupler 4 is at a low level, the third end 4c and the fourth end 4d of the second photoelectric coupler 4 are connected, and the fourth end 4d of the second photoelectric coupler 4 outputs a high level. When the second switch 5 is closed, the second end 4b of the second photoelectric coupler 4 is at a high level, the third end 4c and the fourth end 4d of the second photoelectric coupler 4 are disconnected, and the fourth end 4d of the second photoelectric coupler 4 outputs a low level.

[0079] Exemplarily, the first switch 2 and the second switch 5 may be push button switches, for example.

[0080] In this embodiment, by providing the first switch and the second switch, the first switch and the second switch are used to control the conduction state of the first photocoupler and the second photocoupler, so the circuit is simple and has high reliability.

[0086] Exemplarily, when the first switch 2 is closed and the second switch 5 is opened, the second end 1b of the first photoelectric coupler 1 is at a high level, the third end 1c and the fourth end 1d of the first photoelectric coupler 1 are disconnected, the fourth end 1d of the first photoelectric coupler 1 outputs a low level, and the first end 11a of the first relay 11 is at a low level. The second end 6b of the second wiring terminal 6 outputs a low level signal, the second end 7b of the third photoelectric coupler 7 is at a low level, the loop between the third end 7c and the fourth end 7d of the third photoelectric coupler 7 is turned on, the third end 7c of the third photoelectric coupler 7 outputs a low level, and the second end 11b of the first relay 11 is at a low level. Since the first end 11a and the second end 11b of the first relay 11 are both at a low level, the third end 11c and the fourth end 11d of the first relay 11 are turned on, and the first end of the motor is connected to the positive pole of the DC power supply.

[0087] Since the second switch 5 is disconnected, the second end 4b of the second photocoupler 4 is at a low level, the third end 4c and the fourth end 4d of the second photocoupler 4 are turned on, the fourth end 4d of the second photocoupler 4 outputs a high level, and the first end 12a of the second relay 12 is at a high level.

Since the first end 12a of the second relay 12 is at a high level and the second end 12b is at a low level, the fifth end 12e and the fourth end 12d of the second relay 12 are turned on, and the second end of the motor is connected to the negative pole of the DC power supply.

[0088] When the first end of the motor is connected to the positive pole of the DC power supply and the second end of the motor is connected to the negative pole of the DC power supply, the motor enters the forward rotation mode.

[0089] Exemplarily, when the first switch 2 is opened and the second switch 5 is closed, since the first switch 2 is opened, the second end 1b of the first photocoupler 1 is at a low level, the third end 1c and the fourth end 1d of the first photocoupler 1 are turned on, the fourth end 1d of the first photocoupler 1 outputs a high level, and the first end 11a of the first relay 11 is at a high level.

Since the first end 11a of the first relay 11 is at a high level and the second end 11b is at a low level, the first end 11a and the second end 11b of the first relay 11 are turned on, so that the fifth end 11e and the fourth end 11d of the first relay 11 are turned on, and the first end of the motor is connected to the negative pole of the DC power supply.

[0090] Since the second switch 5 is closed, the second end 4b of the second photoelectric coupler 4 is at a high level, the third end 4c and the fourth end 4d of the second photoelectric coupler 4 are disconnected, the fourth end 4d of the second photoelectric coupler 4 outputs a low level, and the first end 12a of the second relay 12 is at a low level.
