[0021] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0022] In one embodiment, as Figures 1-4As shown, a driving structure of a smart advertising door includes a secondary support base 104, a transmission assembly installation slot 201 is set at the center of the secondary support base 104, a rotating shaft 200 is set inside the transmission assembly installation slot 201, and a driven gear 202 is set at the bottom of the rotating shaft 200. The radius of the driven gear 202 is slightly larger than the rotating shaft 200, so the transmission assembly installation slot 201 is set to a structure that is narrow at the top and wide at the bottom. A fixed column plug hole 203 that passes through the bottom of the secondary support base 104 is set at the center of the lower end of the transmission assembly installation slot 201, and a fixed column 204 is set in the fixed column plug hole 203. The fixed column 204 is connected to the bottom of the driven gear 202, which plays a restraining role when the gear rotates to prevent deflection. A driving gear 205 is also provided on the left side of the driven gear 202 to drive it to rotate. A driving shaft 206 is connected to the driving gear 205, and a power component that provides rotational force is provided on the driving shaft 206; an overload protection component is provided in the power component to protect the motor, and the auxiliary support base 104 is also provided with a reset component for resetting the rotating shaft 200 after rotation.

[0023] In one embodiment, Figure 2 and Figure 4 As shown, the power assembly includes a motor 400 arranged on the upper surface of the auxiliary support base 104, and four motor support columns 401 for supporting the motor 400 are also arranged on the top of the auxiliary support base 104. The motor support columns 401 are arranged in a circular array at the bottom of the motor to ensure the stability of the motor. An active component installation slot 404 is provided inside the auxiliary support base 104, and a motor shaft 402 that cooperates with the motor 400 is provided inside the active component installation slot 404. A motor shaft head 403 is provided under the motor shaft 402, and an overload protection component is connected to the bottom surface of the motor shaft head 403. During normal operation, the motor shaft 402 drives the motor shaft head 403 and the overload protection component to rotate clockwise, and the overload protection component is not triggered.

[0024] In one embodiment, Figure 4 As shown, the overload protection component includes a moving shaft installation groove 500 opened inside the driving shaft 206, a moving shaft 501 is provided on the inner wall of the moving shaft installation groove 500, and a plurality of limiting protrusions 502 in a circumferential array are provided between the outer side of the moving shaft 501 and the inner wall of the moving shaft installation groove 500. The installation groove 500 fixes the moving shaft 501 so that it can only move up and down, and the limiting protrusions 502 limit the left and right shaking of the moving shaft 501. A spring 503 is vertically arranged outside the moving shaft installation groove 500, and the up and down movement of the spring 503 provides displacement space for the moving shaft 501. A sliding gear platform 504 is connected to the top of the moving shaft 501, and two rows of sliding gears 505 that can mesh with each other are symmetrically arranged between the sliding gear platform 504 and the motor shaft head 403. When the sliding gears are meshed, the sliding gear platform 504 and the motor shaft head 403 move as a whole; when the sliding gears are staggered, the sliding gear platform 504 and the motor shaft head 403 move separately.

[0025] In one embodiment, as Figure 1 shown, a fixed frame 101 is connected to the side of the rotating shaft 200. Inside the fixed frame 101, there is an advertising board 100 for displaying advertisements. The advertising board 100 is an LED display screen and can replace the advertising content in real time. On the right side of the rotating shaft 200, there is a main column 102 for cooperating with the opening and closing of the door. At the bottom of the main column 102, there is a main support base 103.

[0026] In one embodiment, as Figure 1 and Figure 2 shown, the reset assembly includes a rotating base 301 connected to the rotating shaft 200. The rotating base 301 is arranged on the upper surface of the secondary support base 104. The rotation of the rotating shaft 200 drives the rotating base 301 to perform circular motion around the rotating shaft 200. On the upper surface of the secondary support base 104, there is a reset base 300 that cooperates with the rotating base 301. One end of the rotating base 301 is provided with two tangent rotating chutes 303 inward. The two sector chutes cooperate with each other to increase the opening and closing angle. Inside the rotating chute 303, there is a rotating slide bar 305 sliding. The top of the rotating slide bar 305 is connected to the lower end of the fixed frame 101. The opening and closing of the door frame drive the rotating slide bar 305 to slide inside the rotating chute 303. At one end of the reset base 300, there is a reset chute 302 inward. The end of the reset chute 302 protrudes to limit the components sliding therein. On the inner wall of the reset chute 302, there is a positioning slide bar 304 that can slide on its surface. There is a fixed positioning ring 306 on the positioning slide bar 304. Symmetrically arranged at the upper end of the rotating slide bar 305, there is a paired positioning ring 307. The positioning ring 306 and the paired positioning ring 307 are connected by a reset spring 308. The same height of the two positioning rings enables the reset spring 308 to always remain horizontal.

[0027] In one embodiment, as Figure 2 shown, at the top of the rotating shaft 200, there is a control panel 600 for controlling the start of the motor 4. The control panel 600 is an intelligent module and can meet functions such as card - swiping to open the door, fingerprint - swiping to open the door, and opening the door through a mobile phone APP. The control panel 600 is electrically connected to the motor 400 and cooperates with the motor.

[0028] In one embodiment, as Figure 1 shown, on the secondary support base 104, protective covers are provided on the outer sides of both the motor assembly and the reset assembly for dust - proof, sun - shading, and preventing external force impact.

[0029] Working principle: When the motor 400 is working properly, the overload protection component will not be triggered; when an intruder violently pushes open the gate, it will cause the fixed frame 101 to drive the rotating shaft 200 and the driven gear 202 to rotate, so that the driving gear 205 and the driving shaft 206 are forced to rotate in the reverse direction. Under the action of rotation, the sliding tooth 505 is squeezed to displace and generate a downward pressure on the sliding tooth platform 504. The sliding tooth platform 504 and the moving shaft 501 as a whole move downward along the inner wall of the moving shaft installation groove 500 through the downward pressure spring 503, thereby disconnecting the motor shaft head 403 and the sliding tooth platform 504, making their movements asynchronous and playing a role in protecting the motor. At the same time, the fixed frame 101 will drive the rotating slide bar 305 to move to the other side of the rotating chute 303, the return spring 308 is stretched, and at the same time, the positioning slide bar 304 is also driven to slide, triggering the return component. Under the action of the elastic force, the return spring 308 will drive the positioning slide bar 304 and the rotating slide bar 305 to approach and complete the reset.

[0030] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
