[0025] The present invention will be further described in conjunction with the following embodiments.

[0026] Depend on Figures 1 to 5 As can be seen, the DC-driven air film rotation structure described in this embodiment includes a fixed base and a rotating disk rotatably mounted on the fixed base; the fixed base is equipped with a drive motor; the output end of the drive motor is equipped with a drive gear; the rotating disk is coaxially equipped with a driven gear ring; the outer wall of the drive gear meshes with the inner wall of the driven gear ring.

[0027] The rotating disk has a first limiter and a second limiter inside the driven gear ring; the first limiter and the second limiter are respectively located on both sides of the drive gear.

[0028] Specifically, in the DC-driven air film rotating structure described in this embodiment, the rotating part of the air film is connected to the rotating disk during use. When the drive motor is working, it drives the drive gear to rotate. Under the meshing cooperation of the drive gear and the driven gear ring, the rotating disk is connected to the rotating part of the air film.

[0029] During the rotation of the rotating disk, when the first or second limit switch reaches the position of the drive gear, the driven gear ring and the rotating disk can no longer rotate, which causes the current of the drive motor to increase sharply. After the controller U2 senses the change in current, it drives the drive motor to work in reverse, so that the rotating disk and the rotating parts can reciprocate.

[0030] This embodiment sets up a first limiter and a second limiter. Under the limiting action of the first limiter and the second limiter, the current of the drive motor changes. Thus, the voltage and current direction of the drive motor is realized through the first on-off module and the second on-off module. The reciprocating rotation of the rotating disk and rotating parts can be realized using a DC power supply.

[0031] This embodiment describes a DC-driven air-film rotary structure. The fixed base has a fixed boss; the drive gear is rotatably mounted on the fixed boss; the fixed boss has a first baffle for abutting against a first limiter and a second baffle for abutting against a second limiter; the first baffle and the second baffle are respectively located on both sides of the drive gear. This arrangement prevents the drive gear from directly contacting the first and second limiters, thus protecting the drive gear.

[0032] This embodiment describes a DC-driven air-film rotary structure. The rotating disk has multiple fixing holes along its circumference within the driven gear ring. The first and second limiters are detachably connected to these fixing holes. This configuration allows for changing the positions of the first and second limiters, thereby adjusting the rotation amplitude of the rotating disk and the rotating components.

[0033] This embodiment describes a DC-driven air-film rotary structure. Both the first and second limiters include a first connecting post, a second connecting post, and a connecting plate disposed between the first and second connecting posts. The first and second connecting posts are detachably connected to fixing holes. This configuration ensures that the first and second limiters possess sufficient strength.

[0034] This embodiment describes a DC-driven air-film rotary structure, which further includes a DC power supply and a power circuit; however, the DC power supply and power circuit are not shown in the figure. The DC power supply is connected to the drive motor through the power circuit. The power circuit of this embodiment includes a positive output port, a negative output port, a controller U2, a first on / off module, a second on / off module, and a comparison module. This embodiment describes a DC-driven air-film rotary structure. The first on / off module includes transistors Q1, Q2, and Q3. Transistors Q2 and Q3 are NPN transistors, while transistor Q1 is a PNP transistor. The controller U2 has a first output terminal and a second output terminal. The first output terminal is connected to the base of transistor Q2. The emitter of transistor Q2 is grounded. The collector of transistor Q2 is connected to the base of transistor Q1. The second output terminal is connected to the base of transistor Q3. The emitter of transistor Q3 is connected to a comparator module. The collector of transistor Q3 is connected to the collector of transistor Q1. The base and emitter of transistor Q1 are connected to a DC power supply. The collector of transistor Q1 is connected to the positive output port. This embodiment describes a DC-driven air-film rotary structure. The second on / off module includes transistors Q4, Q5, and Q6. Transistors Q5 and Q6 are NPN transistors, while transistor Q4 is a PNP transistor. The second output terminal is connected to the base of transistor Q5. The emitter of transistor Q5 is grounded. The collector of transistor Q5 is connected to the base of transistor Q4. The first output terminal is connected to the base of transistor Q6. The emitter of transistor Q6 is connected to a comparator module. The collector of transistor Q6 is connected to the collector of transistor Q4. The base and emitter of transistor Q4 are connected to a DC power supply. The collector of transistor Q4 is connected to a negative output port. The DC-driven air-film rotary structure described in this embodiment includes a comparator U1 in the comparison module; the positive output terminal of the comparator U1 is connected to a reference voltage; and the negative input terminal of the comparator U1 is connected to the emitter of transistor Q3 and the emitter of transistor Q6, respectively.

[0035] Specifically, when using it, first connect the positive output port and the negative output port to the two ends of the drive motor respectively.

[0036] When the motor needs to rotate in the forward direction, controller U2 outputs a high level at the first port and a low level at the second port, turning on transistor Q2 and turning off transistor Q3. This results in a lower base voltage for transistor Q1, causing it to turn on. Additionally, because controller U2 outputs a high level at the first port and a low level at the second port, transistor Q6 turns on and transistor Q5 turns off, resulting in a higher base voltage for transistor Q4, causing it to turn off. At this point, the DC power supply, transistor Q1, the positive output port, the drive motor, the negative output port, transistor Q6, resistor R4, and ground form a circuit, driving the motor to rotate in the forward direction.

[0037] When the first limit switch abuts against the first baffle, the current of the drive motor increases sharply, causing the voltage at the negative input terminal of comparator U1 to be greater than the voltage at the positive input terminal of comparator U1. Comparator U1 outputs a feedback signal to controller U2, causing controller U2 to output a high level at the second port and a low level at the first port, so that the DC power supply, transistor Q4, negative output port, drive motor, positive output port, transistor Q3, resistor R4 and ground form a loop, and the drive motor rotates in the reverse direction.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
