[0002] DC motor magnets are a type of permanent magnet primarily used in permanent magnet motors, and they have a crucial impact on motor performance. The principle behind these magnets is that exchange coupling exists between adjacent electrons in ferromagnetic materials, allowing their spin magnetic moments to spontaneously align within a tiny region, forming a small area of ​​spontaneous magnetization.

[0003] If the magnetic shoe of a DC motor is installed upside down, it will easily cause the direction of the motor's magnetic field to be opposite to the direction of the magnetic field of the rotor coil, causing the direction of the motor's torque to change, and then causing the motor to reverse. The output shaft of the DC motor will turn in the opposite direction, and the components connected to it may not be able to operate normally; therefore, the present application proposes a DC motor direction detection device for detecting whether the magnetic shoe of a DC motor is installed upside down.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-Figure 5 A DC motor steering detection device includes a detection base plate 1 and a detection frame 2. The detection frame 2 is provided with a clamping mechanism 3 for clamping and loosening the DC motor. It should be noted that there are two clamping mechanisms 3, and the two clamping mechanisms 3 are symmetrically distributed about the center line of the detection frame 2. The clamping mechanism 3 includes a support plate 301. The threaded hole in the support plate 301 is connected to the adjusting screw 302 through a thread. The other end of the adjusting screw 302 is connected to the adjusting plate 303 through a bearing seat. The lower end surface of the adjusting plate 303 is in contact with the upper end surface of the detection frame 2. The DC motor is fixed to the detection frame 2 through the clamping mechanism 3, and one side of the output shaft of the DC motor needs to be aligned with the coupling 7.

[0026] Further, the lower end of the detection frame 2 is provided with a moving plate 4, the moving plate 4 is connected with two parallel guide rails 5, the guide rails 5 are arranged on the upper end of the detection base plate 1, and the moving plate 4 is provided with a locking mechanism 6 on the detection base plate 1. When the DC motor moves to the specified position with the moving plate 4, the locking mechanism 6 can lock the position of the moving plate 4 on the detection base plate 1, so as to avoid the sliding of the moving plate 4 in the process of detection by the DC motor. The moving plate 4 and the guide rail 5 make it more convenient for the DC motor to move relative to the detection base plate 1. Therefore, when the moving plate 4 is connected with the coupling 7 and other components, the process of carrying is omitted, and the assembly and disassembly are more relaxed.

[0027] Specifically, the locking mechanism 6 includes a movable locking frame 601 and a fixed locking frame 603, which are respectively installed on the moving plate 4 and the detection base plate 1. A locking plate 602 is connected in the movable locking frame 601 through a rotating shaft, and a locking groove matched with the locking plate 602 is arranged in the fixed locking frame 603. Figure 2 As shown in the figure, when the locking plate 602 is inserted into the locking groove, the movable locking frame 601 and the fixed locking frame 603 cannot move left and right relative to each other. In addition, the guide rail 5 and other components limit the relative position between the detection frame 2 and the detection base plate 1, so that the relative position between the detection frame 2 and the detection base plate 1 is fixed.

[0028] Further, the DC motor is connected with a power supply box, the power supply box provides DC power for the DC motor, and the input current allows the DC motor to rotate. The output shaft of the DC motor is matched with the coupling 7, the other end of the coupling 7 is connected with a power piece 8, and the power piece 8 is inserted with a connecting piece 9.

[0029] Specifically, the power piece 8 includes a fan-shaped plate 801, a plurality of fan-shaped plates 801 are circumferentially arranged around the center line of the power piece 8, one end of the fan-shaped plate 801 close to the power piece 8 is connected with an elastic component 802, and a limiting plate 803 for limiting the maximum rotation range of the fan-shaped plate 801 is arranged on the power piece 8. At the same time, a plurality of arc grooves 901 and inclined grooves 902 are arranged in the connecting piece 9, and the arc grooves 901 are connected with the inclined grooves 902. Figure 1 As shown in the figure, the fan-shaped plate 801 abuts against the inclined groove 902. If the magnetic shoe in the DC motor is installed correctly, the power piece 8 and the fan-shaped plate 801 rotate counterclockwise, the fan-shaped plate 801 is extruded into the power piece 8 by the arc groove 901, and the connecting piece 9 rotates relative to the power piece 8. That is, the power piece 8 rotates while the connecting piece 9 does not move. Therefore, a corresponding friction piece needs to be installed at the connecting piece 9. When the connecting piece 9 rotates relative to the power piece 8 or has a relative rotation trend, a certain friction force can be provided. The friction force allows the power piece 8 to rotate counterclockwise without driving the connecting piece 9 to rotate.

[0030] If the magnetic shoe in the DC motor is installed incorrectly, the DC motor will rotate clockwise. At this time, the fan-shaped plate 801 can drive the inclined groove 902 and the connecting piece 9 to rotate.

[0031] Furthermore, a detection circuit is provided on the detection base plate 1 , and the detection circuit is connected to the alarm 14 . When the power member 8 drives the connecting member 9 to rotate, the detection circuit can be connected, and the connected detection circuit can activate the alarm 14 .

[0032] Specifically, the detection circuit is arranged inside the detection box, and the part of the connector 9 inserted into the detection box is provided with a convex plate 10. The outer wall of the convex plate 10 is abutted against two lifting plates 11. The second connection end provided on the lifting plate 11 is aligned with the first connection end 12 in the detection box. The two second connection ends are connected by wires, and the first connection end 12 is connected to the alarm 14 and the power supply through wires to form a detection circuit. When the first connection end 12 is connected to the second connection end, the detection circuit is turned on, current flows, and the alarm 14 is turned on. It should be noted that the first connection end 12 is connected to the spring 13, and the spring 13 is connected to the detection box. The lifting plate 11 and the second connection end can push the first connection end 12 to move a certain distance. In this way, during the rotation of the connector 9, there is a period of time when the detection circuit is in a connected state. In this way, the connector 9 repeatedly rotates, and the alarm 14 lights up and turns off many times, serving as a warning. It should be noted that the lifting plate 11 located on the lower side needs to be connected to an elastic mechanism so that it always fits with the convex plate 10, and the lifting plate 11 is connected to a guide frame, which allows it to move only up and down.

[0033] Working principle:

[0034] Place the DC motor on the detection frame 2, push the movable plate 4 and the DC motor along the guide rail 5, and move the DC motor to a position close to the coupling 7. Then, connect the output shaft of the DC motor to the coupling 7. At this time, power the DC motor through the junction box.

[0035] After the DC motor is powered on, its output shaft will rotate, which drives the power part 8 to rotate through the coupling 7. If the connecting member 9 connected to the power part 8 rotates due to the push of the power part 8, the convex plate 10 on the connecting member 9 will drive the upper and lower lifting plates 11 to move in opposite directions until the two first connecting ends 12 are connected to the corresponding second connecting ends. At this time, the detection circuit is started, the alarm 14 is energized, and an alarm is sounded, which means that the magnetic tiles of the DC motor are installed upside down. Otherwise, it means that the magnetic tiles of the DC motor are installed normally. This can be used to determine whether the magnetic tiles in the DC motor are installed correctly.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
