Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to an outdoor integrated backlit waterproof display structure. Background Technology

[0002] In today's era of rapid information technology development, the advertising industry is facing increasingly fierce competition, and advertisers are investing more attention and resources in promoting their advertising messages. Besides online advertising, outdoor advertising, with its unique advantages, has become an indispensable part of advertising strategies. Outdoor displays, as an emerging force in future outdoor advertising media, have been widely used in the commercial advertising field due to their intuitive and vivid display effects. Common application scenarios include shopping malls, commercial streets, train stations, airports, and other places with high population density and mobility. Outdoor displays can play diverse advertising content, covering various forms such as images, videos, and animations. They possess significant characteristics such as mobility, persuasiveness, targeting, and effectiveness, effectively attracting pedestrian attention and greatly improving the advertising's dissemination effect.

[0003] For outdoor displays, waterproofing is crucial for stable operation and extended lifespan. Several patents address waterproofing designs for outdoor displays. For example, patent CN217405042U discloses an outdoor display with a structure including a display body and an external module, the latter being detachably mounted on the outside of the display body. This design separates the display body from the external module, achieving a seal between them. This not only facilitates disassembly, replacement, and maintenance, improving efficiency, but also reduces operating and maintenance costs, thus meeting the needs of a wider range of applications. The specific waterproofing structure in this patent includes an air inlet and an air outlet. The air inlet contains an airflow guide plate and a detachable filter, while the air outlet is equipped with a waterproof baffle.

[0004] While the waterproof baffle design at the air vents used in the aforementioned patents can effectively prevent rainwater backflow to some extent, its waterproofing effect still has limitations under extreme weather conditions, such as strong winds accompanied by heavy rain. High-speed airflow may alter the trajectory of rainwater, blowing it behind the baffle and into the housing, potentially damaging the internal components of the display. Therefore, existing waterproofing technologies for outdoor displays still have room for further improvement and optimization to enhance their reliability and stability in harsh outdoor environments. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides an outdoor integrated backlit waterproof display structure that is compact and helps to enhance sealing and reliability.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] An outdoor integrated backlit waterproof display structure includes tempered glass, a back panel, and a profile frame on all four sides. The profile frame, tempered glass, and back panel surround and form a cavity. A liquid crystal panel and optical sleeve are sequentially arranged along the back side of the tempered glass within the cavity. An L-shaped edge sealing plate extends from the front end of the profile frame, with the edge of the tempered glass embedded in the edge sealing plate. When viewed perpendicular to the tempered glass, the edge of the tempered glass and the edge sealing plate overlap. A sealing groove is provided at the joint between the tempered glass and the edge sealing plate, and a waterproof strip is provided at the joint between the profile frame and the back panel.

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] like Figures 1 to 10 As shown, this utility model claims protection for an outdoor integrated backlit waterproof display structure, including tempered glass 1, a back plate 2, and profile frames 3 located on four sides. Adjacent profile frames 3 are fixed together by clamps. The profile frames 3, tempered glass 1, and back plate 2 surround and form a cavity. A liquid crystal panel 4 and an optical sleeve 5 are sequentially arranged along the back side of the tempered glass 1 within the cavity. Specifically, a film support member 9 and a film pressure strip 10 are provided on the inner side of the profile frame 3. The tempered glass 1 and liquid crystal panel 4 are clamped and fixed between the edge sealing plate 302 and the film support member 9, and the optical sleeve 5 is clamped and fixed between the film support member 9 and the film pressure strip 10. Furthermore, a pin is also provided on the inner side of the back plate 2. In the assembled state, the pin has a supporting function for the components in front. Figure 5 as well as Figure 6 As can be seen, after the clamping installation is performed as described above, screws are screwed into one side of the diaphragm pressure strip 10 and connected and locked to the diaphragm support 9 to fix the tempered glass 1, the LCD panel 4 and the optical sleeve 5. In order to improve the tightness, pads can be placed on the side of the diaphragm support 9 and the diaphragm pressure strip 10 to enhance the squeezing effect.

[0033] The front end of the profile frame 3 extends to form an L-shaped edge sealing plate 302. The edge of the tempered glass 1 is embedded in the edge sealing plate 302, and when viewed from a direction perpendicular to the tempered glass 1, the edge of the tempered glass 1 and the edge sealing plate 302 overlap. A sealing groove 7 is provided at the joint between the tempered glass 1 and the edge sealing plate 302. During assembly, the sealing performance between the tempered glass 1 and the edge sealing plate 302 is enhanced by injecting sealant into the sealing groove 7, preventing moisture from entering from this joint. A waterproof strip 8 is provided at the joint between the profile frame 3 and the back plate 2. The waterproof strip 8 helps to ensure the sealing performance between the profile frame 3 and the back plate 2. Thus, through the sealing effect of the above two points, the profile frame 3, the tempered glass 1, and the back plate 2 surround and form a cavity to achieve a good water-sealing effect, making it difficult for moisture to enter.

[0034] The inner surface of the edge sealing plate 302 facing the adhesive groove has a rough surface 3021 with a roughness Ra of 3.2–6.3 μm. In this embodiment, a roughness Ra of 4.5 μm is preferred. Practice has shown that a roughness Ra of 3.2–6.3 μm helps to improve the adhesion of the sealant. The edge of the edge sealing plate 302 is recessed towards the tempered glass 1 by 0.5–1 mm; in this embodiment, a recess of 0.8 mm is preferred. The recessed edge of the edge sealing plate 302 forms a structure similar to a "dam". When water comes into contact with the edge sealing plate 302, the recessed edge can change the direction of water flow, preventing water from directly flowing into the adhesive groove 7 or the interior of the display. This structural design increases the path and difficulty of water intrusion, further improving the waterproof effect.

[0035] A fixing strip 11 is connected to the profile frame 3. Fasteners 12 pass through the back plate 2 and are connected to the fixing strip 11, thereby locking the back plate 2. The fasteners 12 can be bolts or screws; a waterproof rubber ring is provided inside the fasteners 12, which is fitted onto the fasteners 12 to enhance the sealing effect and prevent moisture from entering.

[0036] The fixing strip 11 includes a top insert 1101, and a corresponding slot 301 is provided on the profile frame 3. The insert 1101 is inserted into the slot 301, and the insert 1101 extends obliquely towards the back plate 2. After the oblique insert 1101 is inserted into the slot 301, the connection between the back plate 2 and the profile frame 3 is tightened by the fastener 12. At the same time, the oblique structure produces a self-locking effect when subjected to external force. That is, the greater the external force, the greater the friction and compression force between the insert 1101 and the slot 301, which helps to enhance the tightness of the connection between the back plate 2, the profile frame 3, and the fixing strip 11.

[0037] The frame 3 is equipped with a fastener 303, which helps to fix the infrared probe or other sensors and controllers.

[0038] Combination Figure 5 as well as Figure 6 See, the lower end of the diaphragm strip 10 is inclined at 10-20° towards the back plate 2, and the gap between it and the back plate 2 is ≤0.5mm.

[0039] The inclined setting at the lower end of the diaphragm strip 10 and the reserved small gap (≤0.5mm) can play a certain role in protection and sealing. The small gap can reduce the possibility of moisture and dust entering the inside of the display. Furthermore, the inclined diaphragm strip 10 can guide moisture and dust to flow away or slide off along the inclined direction of the diaphragm strip 10, without affecting the LCD panel 44 and the optical cover 55.

[0040] A rear cover plate 13 is screwed to the rear of the back panel 2, and a rear shell 14 is screwed to the rear cover plate 13. A cooling fan 15 is mounted on the rear shell 14, and an opening 1301 is provided on the rear cover plate 13, with the cooling fan 15 correspondingly mounted on the opening 1301. An air outlet 1302 is provided on the edge of the rear cover plate 13, and the opening 1301 and the air outlet 1302 are in air communication. The heat generated inside the monitor during operation will cause the back panel 2 to heat up. Since the rear cover plate 13 is closed on the back panel 2, when the cooling fan 15 is turned on, it will introduce external cool air into the space between the rear cover plate 13 and the back panel 2, and finally exhaust it through the air outlet 1302, so that the airflow can dissipate the heat generated inside the monitor during operation.

[0041] A protective mesh plate 16 is provided on the rear shell 14 corresponding to the cooling fan 15. The protective mesh plate 16 can intercept most of the dust and debris, so that these contaminants mainly adhere to the surface of the mesh plate and avoid affecting the cooling fan 15. The back plate 2 is provided with an air distribution plate 19 and a mesh partition 20. The air distribution plate 19 helps to disperse the air blown in from the cooling fan 15 to both sides for heat dissipation. The mesh partition 20 is provided with several holes. When the air flows to the mesh partition 20, it can change the airflow pattern, that is, make the airflow form a certain vortex, thereby improving the heat dissipation effect.

[0042] Handles 17 are symmetrically arranged on both sides of the back panel 2. The vertical distance from the center line of the handle 17 to the top and bottom of the waterproof back display is 1:1. This setting not only conforms to the ergonomic principle, but also allows the force applied by the mover to be transmitted more directly to the center of gravity of the waterproof back display, and the force on the upper and lower ends of the waterproof back display is also more balanced.

[0043] The rear cover 14 has a downward-facing cable port 18. The power cord is plugged into the cable port 18 to transmit power or signals to the internal components of the display. The downward-facing design of the cable port 18 prevents water from seeping in, thus improving safety. Furthermore, the rear cover 14 is also equipped with a sealing plug 21 made of rubber. Excess cable in the cable port 18 is sealed by inserting the sealing plug 21, further preventing moisture from entering.

[0044] This invention enhances the seal between the tempered glass 1 and the edge sealing plate 302 by injecting sealant into the sealing groove 7, and by providing a waterproof strip 8 at the joint between the profile frame 3 and the back plate 2. This effectively prevents moisture from entering the monitor, greatly improving the reliability and stability of the monitor in harsh outdoor environments, reducing malfunctions and damage caused by water ingress, and extending the monitor's service life. In addition, since the sealing groove 7 and the waterproof strip 8 are compactly located on the front and rear sides of the profile frame 3, the profile frame 3 can achieve an extremely narrow effect, which is beneficial for increasing the screen-to-body ratio and is suitable for multi-screen splicing.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
