Description

Technical Field

[0001] The utility model belongs to the technical field of direct current motors, and in particular relates to a direct current motor driving force steering structure. Background Art

[0002] Electromagnetic theory has been applied to motor practice for more than 200 years. During this period, the types of motors have been constantly updated, and a mature technical series of AC asynchronous motors, DC synchronous motors and motors has been formed. The application of motors has greatly improved productivity and product quality, greatly facilitated automatic control and remote control, and greatly reduced heavy physical labor. Various types of motors have become an indispensable source of power for survival and development in industry, agriculture, science and technology, national defense and people's daily life. DC motor refers to a rotating motor that can convert DC power into mechanical energy. It is a motor that can realize the conversion of DC power and mechanical energy.

[0003] When the existing DC motor needs to change its rotation direction, it is usually achieved by changing the positive and negative output of the power supply, which has high requirements on the configuration of the power supply and high cost. Utility Model Content

[0004] The main purpose of the utility model is to provide a DC motor driving force steering structure, which does not need to change the positive and negative output of the power supply. By changing the connection structure of the internal circuit, the DC motor steering can be conveniently and effectively changed, and the cost requirement is relatively lower.

[0005] In order to achieve the above purpose, the utility model provides a DC motor driving force steering structure, which includes a rotating disk, two electrode sheets are symmetrically installed at the bottom of the rotating disk, and the two electrode sheets are respectively connected to the positive and negative poles of the power supply. A conductive sheet is provided below the motor sheet, and a wire is provided on the electrode sheet. The other end of the wire is wound around the outer edge of the rotating disk and extends from the opposite side.

[0006] The utility model provides a DC motor driving force steering structure, in which an electrode sheet and a conductive sheet are arranged in the power supply circuit of the DC motor, when the electrode sheet and the conductive sheet are in contact, the circuit of the DC motor is turned on, the wire of the electrode sheet is relatively long, and after entering from the outside, it is wound around the outer edge of a rotating disk and connected to the electrode sheet, and since the wire is relatively long, the rotating disk can be rotated, and the rotating direction is the direction in which the wire is relaxed, and after the electrode sheet is rotated to the other side, the conductive sheet contacted by the electrode sheet changes, thereby changing the direction of the current inside the DC motor, thereby changing the driving force steering of the DC motor, and since the method only needs to rotate the rotating disk to achieve the change of the driving force direction of the DC motor, it is simple, convenient and has lower cost.

[0007] In a possible implementation, a circle of circular grooves is arranged on the outer side of the rotating disk, and the wire is arranged in the circular grooves. When the electrode sheet is away from the wire entry end, the wire is pulled and placed in the circular grooves.

[0008] In a possible implementation, the wires of the two electrode sheets are respectively wound around different sides of the rotating disk. When the rotating disk rotates to make the electrode sheet close to the wire entry end, the wires on both sides can be relaxed.

[0009] In a possible implementation, a mounting shaft is disposed above the rotating disk, and a rotating slot is disposed between the mounting shaft and the rotating disk. The rotating slot is mounted on a housing of the DC motor.

[0010] In a possible implementation, a rotating knob is provided on the top of the mounting shaft. By rotating the knob, the rotating disk can be rotated, thereby changing the conductive sheet that the electrode sheet contacts. BRIEF DESCRIPTION OF THE DRAWINGS
