Description

Technical Field

[0001] This utility model relates to an outdoor advertising light box, and more specifically, to an outdoor advertising scrolling light box. Background Technology

[0002] Outdoor scrolling light boxes are a new type of outdoor advertising that combines the advantages of scrolling light boxes with smart technology. Specifically, they employ a digital scrolling system, using timed control to rotate the images at intervals, thus displaying multiple advertisements within a single light box. Furthermore, outdoor scrolling light boxes are typically equipped with LED displays for publishing advertising content, public service announcements, or enhancing visual appeal.

[0003] Existing outdoor advertising scrolling light boxes are exposed to variable outdoor environments, especially in windy weather. Strong winds often bring flying sand, stones, leaves, and other debris. If these objects are blown by the wind, they can directly impact the light box's display screen. This not only scratches or damages the screen surface but also affects the display quality and can even cause the screen to crack.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an outdoor advertising scrolling lightbox, which aims to solve the problem that the display screen of the lightbox is easily damaged in harsh environments.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an outdoor advertising scrolling lightbox, including a base, a column fixedly installed on the upper end of the base, a lightbox body fixedly installed on the upper end of the column, a display screen fixedly installed on the front end of the lightbox body, an adjustment component provided on the upper side of the front end of the lightbox body, a sunshade plate fixedly installed on the outer surface of the adjustment component, a groove opened at the lower end of the sunshade plate, a sealing plate movably connected in the groove, an electric push rod fixedly installed on the front end of the sunshade plate, and the electric push rod and the sealing plate fixedly connected.

[0007] The present invention is further configured such that: the adjustment component includes a fixing plate, there are two fixing plates, and the opposite surfaces of the two fixing plates are movably interlocked with a rotating shaft, a servo motor is fixedly installed at the right end of the rotating shaft, the sunshade plate is fixedly connected to the rotating shaft, and the fixing plate is fixedly connected to the front end of the light box body.

[0008] The present invention is further configured such that the area of ​​the sealing plate is the same as the area of ​​the display screen.

[0009] The present invention is further configured such that the base and the column maintain a vertical positional relationship.

[0010] The present invention is further configured such that the area of ​​the sealing plate is the same as the size of the groove.

[0011] The present invention is further configured such that: a wind speed sensor, a raindrop sensor and a PLC controller are fixedly installed on the top of the light box body, and the PLC controller is electrically connected to the wind speed sensor, the raindrop sensor, the servo motor and the electric push rod respectively.

[0012] In summary, this utility model has the following beneficial effects:

[0013] Through the coordinated design of the sunshade and sealing plate, the display screen can be effectively protected from direct impact and damage under severe weather conditions (such as strong winds and sandstorms). The sunshade rotates counterclockwise to a position parallel to the lightbox body, reducing the exposed area of ​​the display screen and mitigating the impact of wind pressure. The electric push rod drives the sealing plate forward until it contacts the surface of the display screen, forming a tight sealing barrier that prevents windblown sand, dust, or other impurities from entering the display screen area, thus protecting the display screen, extending its service life, and effectively protecting it from damage in windy weather.

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] An outdoor advertising scrolling lightbox, such as Figures 1 to 4As shown, the light box includes a base 1, with a column 2 fixedly installed on the upper end of the base 1. The base 1 and the column 2 are in a vertical position. A light box body 3 is fixedly installed on the upper end of the column 2. A display screen 4 is fixedly installed on the front end of the light box body 3. An adjustment component 5 is provided on the upper side of the front end of the light box body 3. A sunshade 6 is fixedly installed on the outer surface of the adjustment component 5. A groove 7 is provided at the lower end of the sunshade 6. A sealing plate 8 is movably connected in the groove 7. The area of ​​the sealing plate 8 is the same as the size of the groove 7 and the area of ​​the display screen 4. An electric push rod 9 is fixedly installed at the front end of the sunshade 6. The electric push rod 9 and the sealing plate 4 are connected in a vertical position. The sealing plate 8 is fixedly connected, and the sunshade plate 6 is made of high-strength aluminum alloy material: lightweight, sturdy, corrosion-resistant, and has a certain strength and rigidity. The sealing plate 8 is made of engineering plastic (such as PC, PMMA acrylic): the surface hardness is moderate, it is not easy to scratch the display screen, and it is easy to process into a flat plate shape. An elastic sealing ring is set on the circumferential edge of the sealing plate 8 (not shown in the figure, using existing technology). The silicone sealing ring is resistant to high and low temperatures, aging, and has good elasticity. When the sealing plate 8 is pushed by the electric push rod 9 to adhere to the display screen 4, the silicone sealing ring undergoes elastic deformation, filling the gap between the sealing plate 8 and the display screen 4 to form a reliable waterproof and dustproof seal.

[0024] like Figure 2 As shown, the adjustment component 5 includes a fixing plate 51. There are two fixing plates 51, and the opposing surfaces of the two fixing plates 51 are movably connected to a rotating shaft 52. A servo motor 53 is fixedly installed at the right end of the rotating shaft 52. The sunshade plate 6 is fixedly connected to the rotating shaft 52. The fixing plate 51 is fixedly connected to the front end of the light box body 3. The servo motor 53 drives the rotating shaft 52 to rotate counterclockwise, thereby driving the sunshade plate 6 to rotate counterclockwise to a position parallel to the light box body 3.

[0025] like Figure 1 and Figure 4 As shown, a wind speed sensor 10, a raindrop sensor 11, and a PLC controller 12 are fixedly installed on the top of the light box body 3. The PLC controller 12 is electrically connected to the wind speed sensor 10, the raindrop sensor 11, the servo motor 53, and the electric push rod 9. The PLC controller 12 is preset with a first wind speed threshold (e.g., 10 m / s) and a second wind speed threshold (e.g., 15 m / s).

[0026] Working principle: Under normal operating conditions, the sunshade 6 is driven by the servo motor 53 and maintained in an extended state at an acute angle to the lightbox body 3 (for sun shading). The sealing plate 8 is stored in the groove 7, and the display screen 4 displays advertising content normally. When the wind speed detected by the wind speed sensor 10 exceeds the first wind speed threshold, or when the rain sensor 11 detects rainfall, the PLC controller 12 controls the servo motor 53 to start, driving the rotating shaft 52 to rotate counterclockwise, causing the sunshade 6 to rotate towards the lightbox body 3 until it is parallel to the front end of the lightbox body 3, forming the first wind barrier. This reduces the direct impact of wind on the display screen 4 to a certain extent because it reduces the exposed area of ​​the display screen 4 and lowers the wind pressure on the display screen. As a result of the influence of wind speed sensor 10, when the wind speed detected by wind speed sensor 10 further exceeds the second wind speed threshold, PLC controller 12 further controls electric push rod 9 to start, pushing sealing plate 8 out of groove 7 until its front end is tightly attached to the surface of display screen 4, forming a second sealing barrier, effectively preventing wind, sand, rain and debris from intruding, and effectively protecting display screen 4 from damage by strong winds. When the ambient wind speed is continuously lower than the first wind speed threshold and there is no rain signal for a preset time (e.g., 10 minutes), PLC controller 12 controls electric push rod 9 to retract, retracting sealing plate 8 into groove 7, and then controls servo motor 53 to drive sunshade plate 6 back to the unfolded sunshade state, and display screen 4 resumes normal display.

[0027] In summary, the coordinated design of the sunshade 6 and the sealing plate 8 effectively protects the display screen 4 from direct impact and damage under harsh weather conditions (such as strong winds and sandstorms). The sunshade 6 rotates counterclockwise to a position parallel to the lightbox body 3, reducing the exposed area of ​​the display screen 4 and mitigating the impact of wind pressure. The electric push rod 9 drives the sealing plate 8 forward until it contacts the surface of the display screen 4, forming a tight sealing barrier that prevents windblown sand, dust, or other impurities from entering the display screen 4 area, thus protecting the display screen 4 and extending its service life.

[0028] In this embodiment, the electric actuator 9 can be an electric actuator 9 with a thrust of 200N, a stroke of 150mm, and an IP65 protection rating; the servo motor 53 can be a closed-loop control servo motor 53 with a rated torque of 1.5N·m and an incremental encoder; the wind speed sensor 10 can be a standard wind speed transmitter with a measurement range of 0-30m / s and an output signal of 4-20mA; the raindrop sensor 11 can be a waterproof rain sensing module based on the principle of conductivity; and the PLC controller 12 can be a micro programmable logic controller with at least 2 analog inputs, 2 digital inputs, and 2 relay outputs.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
