Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around", etc. Indicates the orientation or positional relationship, only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, are constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention .

1-3, the present invention is an electronic display card for a smart campus based on a cleaning mechanism, including an installation frame 1; the installation frame 1 is installed with an electronic display card 101; the installation frame 1 is fixed on the ground through a support column.

Two opposite sides of the mounting frame 1 are welded or screwed with a box body 102, and the box body 102 has a cuboid structure; the box body 102 is provided with a vertically arranged straight slot 103 at a position relative to the electronic display board 101; the inner wall of the box body 102 is screwed with a Bar block 2 and guide rail 3.

Both the bar-shaped block 2 and the guide rail 3 are arranged in parallel with the straight slot 103 , and the guide rail 3 is located between the bar-shaped block 2 and the straight slot 103 .

The bar-shaped block 2 has a waist-shaped hole structure, that is, the upper and lower ends are semi-circular structures, and the peripheral sides of the bar-shaped block 2 are evenly provided with teeth 201, so that the teeth 201 are evenly distributed on both sides of the bar-shaped block 2. And the two curved surfaces at the foot of the mountain connected to it.

The guide rail 3 is slidably connected with a slider 301; the slider 301 is slidably connected with a strip plate 4; the surface of the slider 301 can be provided with a T-shaped chute or a dovetail groove, and the cross-sectional shape of the strip plate 4 is a T-shaped or dovetail matched with it. shape, to realize the sliding connection between the strip-shaped plate 4 and the slider 301, and the strip-shaped plate 4 is arranged horizontally.

A spring 302 is fixedly connected to one opposite side of the slider 301 ; both springs 302 are fixedly connected to the upper surface of the strip plate 4 , so that when the strip plate 4 slides left and right relative to the slider 301 , both springs 302 can receive the pulling force and elastic force of the spring 302 .

As shown in Figures 3 and 4, one end of the strip plate 4 is rotatably connected with a cleaning roller 5 for cleaning the electronic display card 101; the other end of the strip plate 4 is fixedly connected with a motor 401 through a motor frame; the rotating shaft of the cleaning roller 5 passes through The strip plate 4 is fixedly connected with a driven wheel 501 . The rotating shaft of the cleaning roller 5 is in clearance fit with the straight slot 103, so that the cleaning roller 5 has a space to move in the horizontal direction.

The output shaft of the motor 401 is fixedly connected with a driving wheel 402 which is drivingly connected with the driven wheel 501 , and the driven wheel 501 and the driving wheel 402 may be sprockets or synchronous pulleys. The output shaft of the motor 401 penetrates the strip plate 4 , and is fixedly connected with a gear 403 that meshes with the teeth 201 .

When cleaning is required, the motor 401 rotates clockwise, the gear 403 moves from top to bottom along the side of the strip block 2 away from the straight slot 103, and the driven wheel 501 is driven by the driving wheel 402 to rotate clockwise, and the cleaning roller 5 Make a clockwise rotation. The movement of the gear 403 drives the strip plate 4 to move from top to bottom through the slider 301 , so that the cleaning roller 5 can clean the surface of the electronic display card 101 from top to bottom.

The cleaning roller 5 rotates clockwise, which can move the dust on the surface of the electronic display card 101 from top to bottom, which is beneficial to improve the cleaning effect. Surface cleaning.

In addition, the transmission ratio between the driving wheel 402 and the driven wheel 501 is less than 1, so that the rotation speed of the cleaning roller 5 is increased, thereby realizing more effective cleaning of the electronic display board 101 during the moving process, and improving the cleaning effect.

When the gear 403 moves from the lower end of the bar block 2 to the other side, at this time, the cleaning roller 5 is pushed away from the electronic display card 101 by the bar plate 4, so that the cleaning roller 5 is separated from the surface of the electronic display card 101, When the gear 403 continues to rotate, it drives the strip plate 4 to move from bottom to top and returns to the top of the strip block 2 , that is, the cleaning roller 5 is driven to the top of the electronic display card 101 .

If it is necessary to continue cleaning, the motor 401 continues to work to realize the cyclic cleaning of the electronic display card 101 .

In addition, during the movement of the gear 403 along the bar block 2, since the bar plate 4 is respectively subjected to the pulling force and elastic force of the springs 302 on the left and right sides of the slider 301, the gear 403 and the teeth 201 on the bar block 2 are always kept in good condition. The meshing state ensures the overall reliability and stability.

During this process, the cleaning roller 5 is not in contact with the electronic display card 101, so that the cleaning roller 5 only cleans the electronic display card 101 in the process of moving from top to bottom, so as to avoid the cleaning roller 5 from moving from bottom to top. Dust and other sundries are brought to the surface of the electronic display card 101 to cause secondary pollution to the electronic display card 101 .

Preferably, the straight slot 103 is provided with an organ plate; the organ plate is provided with a through hole that fits with the rotating shaft of the cleaning roller 5 , and the straight slot 103 can be closed by the organ plate, thereby reducing the entry of dust or rainwater into the box 102 What happens inside.

In another preferred solution, the inner wall of the box body 102 is fixedly connected with a second guide rail 303 arranged in parallel with the guide rail 3; the second guide rail 303 is slidably connected with a second sliding block 304; The provision of the second guide rail 303 for sliding connection with the strip-shaped plate 4 helps to improve the overall movement stability of the strip-shaped plate 4 .

In addition, the second guide rail 303 and the guide rail 3 are located on both sides of the strip block 2 respectively, so that the force of the strip plate 4 is more balanced, and the sliding stability between the strip plate 4 and the second guide rail 303 and the guide rail 3 is further improved. and reliability.
