[0002] Advertisement is a communication tool that can be spread through newspapers, radio, television, road signs, windows and other media or forms. Advertisement can effectively promote product publicity, make consumers accept new products, and enrich people's material life.

[0003] Currently, the advertisements on existing billboards in the market are relatively simple, and the information can only be changed by manually replacing the internal posters, which results in untimely information replacement and causes the information on some billboards to display the same content for a long time. Therefore, people invented advertising machines, which carry intelligent electronic display screens and regularly replace the network information to be displayed through control terminals. While avoiding the tedious process caused by manual replacement, it also effectively increases the types of advertisements, thereby improving the interactivity of advertising machines and attracting pedestrians to actively browse.

[0004] However, as time goes by, a lot of dust will accumulate on the surface of the display screen of outdoor advertising machines, which will directly affect people's browsing experience. Therefore, corresponding staff are still needed to regularly clean the surface of the display screen. However, with the rapid development of modern society, the display screens of outdoor advertising machines will be contaminated with more dust in just one day, such as advertising machines located at bus stations. However, I, the staff, cannot clean all billboards every day. At the same time, manual cleaning is inefficient, which only leads to poor browsing effects.

[0005] In summary, there is a need for a device that can perform self-cleaning on the display screen of an outdoor advertising machine, so as to achieve the purpose of regular and effective cleaning of the display screen, reduce the inefficiency and inconvenience of cleaning caused by manual cleaning of the display screen, and thus improve the browsing effect.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0026] like Figure 1-4 As shown, the utility model provides a self-cleaning multimedia information delivery terminal, including a rectangular frame-shaped outer shell 1 and a display screen 9 arranged in the space surrounded by the outer shell 1, characterized in that: the surface of the opposite side of the two vertical arms of the outer shell 1 is respectively concave with a first receiving groove 11, and a self-cleaning device 2 is respectively provided in the two first receiving grooves 11; the self-cleaning device 2 includes a first motor 21, and a connecting rod 22 including M arms is fixedly connected to the output end of the first motor 21, and a plurality of cleaning cloths 28 are provided at the end position of each arm of the connecting rod 22, and the output end of the first motor 21 is connected to the connection of the arm, and M is greater than or equal to 2.

[0027] In one embodiment, a rotating rod 12 is fixedly connected to the top of the display screen 9, and a through groove is opened on the upper horizontal arm of the outer shell 1, and the rotating rod 12 is inserted into the through groove; a protrusion is fixedly connected to the surface of the rotating rod 12 outside the outer shell 1, and the end of the protrusion away from the rotating rod 12 is rotatably connected to a second electric telescopic rod 13, and the other end of the second electric telescopic rod 13 is fixedly connected to the top of the outer shell 1, and the bottom of the display screen 9 is rotatably connected to the lower horizontal arm of the outer shell 1.

[0028] In one embodiment, a cylindrical protective shell 3 is provided on the outer surface of the first motor 21; a second receiving groove 4 is provided in each first receiving groove 11, and a bidirectional screw 5 is provided in each second receiving groove 4. A support block 6 is provided on the bidirectional screw 5 and threadedly connected, and a first electric telescopic rod 7 is fixedly connected to the support block 6, and the end of the first electric telescopic rod 7 away from the support block 6 is fixedly connected to the protective shell 3.

[0029] In one embodiment, except for the side wall fixed to the first electric telescopic rod 7, the other three side walls of the support block 6 are respectively in contact with the three side walls of the second receiving groove 4; a second motor 8 is fixedly connected to one end of the second receiving groove 4, one end of the bidirectional lead screw 5 is fixedly connected to the output end of the second motor 8, and the other end is rotatably connected to the end of the second receiving groove 4 away from the second motor 8.

[0030] When it is necessary to clean the surface of the display screen 9 on which information is projected, the display screen 9 is first pushed to rotate by the second electric telescopic rod 13 until the second electric telescopic rod 13 is opened to the maximum extension position, and then the self-cleaning device 2 is pushed out by the first electric telescopic rod 7 until the surface of the cleaning cloth 28 contacts the surface of the display screen 9. Then the first motor 21 and the second motor 8 start to work respectively, and the first motor 21 drives the cleaning cloth 28 to move regularly in a certain area of ​​the display screen 9 through the connecting rod 22, that is, the connection point of each connecting rod 22 is used as the center of the circle and the support arm is used as the radius to perform a circular motion, so as to effectively clean the surface of the display screen 9 within the range; and the second motor 8 drives the bidirectional lead screw 5 to rotate, thereby driving the support block 6 to drive the first electric telescopic rod 7 and the self-cleaning device 2 to reciprocate, so as to expand the contact area between the cleaning cloth 28 and the display screen 9, and the cleaning cloth 28 is moving up and down while performing a circular motion, so as to effectively clean the surface of the display screen 9.

[0031] It should be noted that, after the first electric telescopic rod 7 is opened to the maximum extension position, the surface of the cleaning cloth 28 is in contact with the display screen 9 .

[0032] In one embodiment, the self-cleaning device 2 also includes a disc-shaped positioning plate 23 fixedly connected to the end of each arm of the connecting rod 22, and an annular rack 233 is fixedly connected to the inner edge of each positioning plate 23, and a first internal gear 231 and N second internal gears 232 are provided in each annular rack 233, the first internal gear 231 is concentrically arranged with the corresponding annular rack 233, and the second internal gear 232 in each annular rack 233 is respectively meshed with the corresponding annular rack 233 and the first internal gear 231, and the cleaning cloth 28 is respectively arranged on the surface of the first internal gear 231 and each second internal gear 232 away from the first motor 21, and N is greater than or equal to 1; a second positioning rod 24 is fixedly connected to the surface of each second internal gear 232 close to the first motor 21, and each second positioning rod 24 passes through the corresponding positioning plate 23 and is rotatably connected to the positioning plate 23, and each first internal gear 231 is rotatably connected to the positioning plate 23 through a first positioning rod 25.

[0033] In one embodiment, the cross-section of the second positioning rod 24 is T-shaped, the vertical arm of the second positioning rod 24 contacts the second internal gear 232, and the horizontal arm of the second positioning rod 24 contacts the surface of the positioning plate 23, thereby achieving a limiting effect on the second internal gear 232 and improving the stability of the second internal gear 232 during operation.

[0034] In one embodiment, a first transmission gear 26 is sleeved and fixedly connected to the outer surface of the protective shell 3, and M second transmission gears 27 are meshed on the first transmission gear 26. Each second transmission gear 27 corresponds to the end of each arm on the connecting rod 22, and one end of each first positioning rod 25 away from the first internal gear 231 passes through the positioning plate 23 and the connecting rod 22 in sequence, and is fixedly connected to a second transmission gear 27 respectively.

[0035] In order to further improve the cleaning efficiency of the self-cleaning device 2 on the surface of the display screen 9, the above structure is added. Its working principle is as follows:

[0036] After the first motor 21 is started, the motor drives the connecting rod 22 to rotate, and drives the positioning plate 23 at the end of each arm of the connecting rod 22 to rotate. Under the mutual cooperation of the first transmission gear 26 and the second transmission gear 27, the first internal gear 231 follows the second transmission gear 27 to rotate at a uniform speed along the first transmission gear 26. At the same time, the second internal gear 232 rotates and moves regularly under the limitation of the first internal gear 231 and the annular rack 233. In this way, the cleaning cloth 28 installed on the first internal gear 231 and the second internal gear 232 not only rotates within a fixed range following the first internal gear 231 and the second internal gear 232, but also expands the cleaning area of ​​the cleaning cloth 28 by driving the movement of the first internal gear 231 and the second internal gear 232, thereby greatly increasing the contact area with the display screen 9 during cleaning, thereby improving the cleaning efficiency.

[0037] After cleaning the display screen 9, the first motor 21 and the second motor 8 stop working, and then the first electric telescopic rod 7 drives the self-cleaning device 2 to be retracted into the first storage groove 11 until the self-cleaning device 2 is completely stored in the first storage groove 11, and then the second electric telescopic rod 13 is retracted, driving the display screen 9 to rotate in the opposite direction until the display screen 9 rotates to its original position.

[0038] In one embodiment, after the second electric telescopic rod 13 is fully extended, the angle between the display screen 9 and the horizontal arm of the outer shell 1 is 90 degrees. At this time, the two surfaces of the display screen 9 used to project information are facing the two self-cleaning devices 2; and when the second electric telescopic rod 13 is fully retracted, the display screen 9 and the horizontal arm of the outer shell 1 are parallel to each other.

[0039] It should be noted that the opening width of the first receiving groove 11 is related to the number of M, the number of M determines the number of positioning plates 23 , and the opening width of the first receiving groove 11 is a different multiple of the diameter of the positioning plate 23 according to the number of positioning plates 23 .

[0040] When M is equal to 2, the opening of the first receiving slot 11 is adapted to the diameter of the positioning plate 23. At the same time, the first motor 21 is a stepper motor. When in use, the stepper motor rotates the two positioning plates 23 to be parallel to the opening position of the first receiving slot 11. In this way, when the first electric telescopic rod 7 drives the self-cleaning device 2 to recycle, it will not cause the positioning plate 23 to get stuck with the outer shell 1. When M is greater than 2, such as M is equal to 3, the opening width of the first receiving slot 11 is adapted to the sum of the diameters of the two positioning plates 23, that is, the opening width is twice the diameter of the limit plate.

[0041] In one embodiment, the number M of the arms of the connecting rod 22 is preferably 2.

[0042] In one embodiment, a control switch, a controller and a battery are provided in the lower cross arm of the outer shell 1, and solar panels are provided on both sides of the upper cross arm of the outer shell 1. The solar panels are electrically connected to the battery, and the first motor 21, the second motor 8, the first electric telescopic rod 7 and the second electric telescopic rod 13 are all connected to the control switch, and the control switch is respectively connected to the battery and the controller. The controller is provided with a control system for controlling the rotation angle of the first motor 21, so as to facilitate the control of the rotation angle of the first motor 21 during the shutdown process, so as to facilitate the storage work of the self-cleaning device 2.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
