Description

Technical Field

[0001] This utility model belongs to the field of display device technology, specifically relating to an outdoor high-brightness passive heat dissipation waterproof display device. Background Technology

[0002] In simple terms, a display device is a monitor with built-in display functions, consisting of a protective glass, reinforcing bracket, and display driver installed on the display panel. A touch display device, on the other hand, adds a touch film between the display panel and the protective glass, creating a touch-enabled display. Users can operate the computer by simply touching the icons or text on the screen with their fingers, eliminating the need for traditional keyboards and mice and enabling direct human-computer interaction. As market demand grows, different industries are placing increasingly higher demands on touch display devices, with more and more customization and personalization requirements. When ordinary touch display devices are used outdoors, they are exposed to harsh environments such as high temperatures, strong sunlight, rain, and dust. Therefore, outdoor display devices are typically high-brightness and require waterproofing and dustproofing. After a period of use, the display device may overheat, causing aging and damage to its internal materials and components. Thus, traditional outdoor display devices face a contradiction between high-temperature heat dissipation and waterproofing / dustproof sealing.

[0003] To address the conflict between high-temperature heat dissipation and waterproofing / dustproof sealing in outdoor display devices, Chinese patent document CN218351067U discloses an outdoor display device designed to prevent dust accumulation. This technical solution achieves environmental adaptability through a triple structure: a water-blocking baffle at the top of the casing for waterproofing, a cooling fan at the rear for active cooling, and a dustproof structure outside the cooling fan. However, in practical applications, the inclusion of the water-blocking baffle, cooling fan, and dustproof structure results in a complex technical path, increasing the number of assembly steps.

[0004] Therefore, there is an urgent need to design a new type of outdoor display device that can solve the contradiction between high-temperature heat dissipation and waterproof and dustproof sealing, while also reducing its own assembly process. Utility Model Content

[0005] To overcome the above-mentioned technical problems, this utility model provides an outdoor high-brightness passive heat dissipation and waterproof display device. The display component and the heat dissipation back plate form a passive heat dissipation and waterproof sealing cavity through a protective frame, which effectively solves the contradiction between high-temperature heat dissipation and waterproof and dustproof sealing of outdoor display devices, as well as the technical problems of complicated assembly processes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An outdoor high-brightness passive heat dissipation and waterproof display device includes a protective frame, a display component, and a heat dissipation backplate. The protective frame includes a frame body with an upper support platform and a lower support platform integrally formed on the frame body, perpendicular to the inner surface. The display component includes a cover plate, a heat insulation film, and a display panel, which are fixed in sequence from the outside to the inside. The cover plate is sealed and fixed on the upper support platform, and the heat dissipation backplate is sealed and fixed on the lower support platform. A passive heat dissipation and waterproof sealed cavity is formed between the display component and the heat dissipation backplate through the protective frame.

[0008] Preferably, the cover plate is a touch screen, and the upper surface of the touch screen and the upper surface of the protective frame are on the same horizontal plane.

[0009] Preferably, the cover plate is a glass cover plate, and the upper surface of the glass cover plate and the upper surface of the protective frame are on the same horizontal plane.

[0010] Preferably, the height of the upper support protruding from the inner surface of the frame is less than the height of the lower support protruding from the inner surface of the frame.

[0011] Preferably, the heat dissipation backplate is fixed to the lower support platform through backplate holes and support platform holes, the lower end face of the heat dissipation backplate and the lower end face of the protective frame are on the same horizontal plane, and a waterproof silicone strip is fixed between the heat dissipation backplate and the lower support platform.

[0012] Preferably, the back of the heat dissipation backplate has a plurality of protruding heat dissipation fins uniformly fixed along the length or width direction.

[0013] Preferably, the heat dissipation backplate has a cable pass-through hole in the middle for communication cables to pass through and multiple mounting holes for mounting outdoor display devices onto user brackets, with the mounting holes evenly distributed around the cable pass-through hole.

[0014] The advantages of using this utility model are:

[0015] 1. In this utility model, firstly, a passive heat dissipation and waterproof sealed cavity structure is formed between the display component and the heat dissipation backplate through a protective frame, which enables the display device to work normally outdoors without being affected by harsh environments such as rain, water, and dust. This achieves the synergy of heat dissipation and waterproofing and dustproofing, and improves the outdoor environmental adaptability of the display device.

[0016] Secondly, the design of the heat dissipation backplate provides the foundation for passive heat dissipation of the display device. The backplate serves as both a heat dissipation component and part of the waterproof structure, preventing dust and water from entering the device, which is common with traditional exhaust fan-based air-cooled designs. Furthermore, compared to Chinese patent document CN218351067U, this utility model abandons the traditional separate design of the heat dissipation and waterproof structures, reducing the number of components and assembly steps, improving assembly efficiency, lowering maintenance costs, ensuring service life, and enhancing user experience, thereby significantly improving market competitiveness.

[0017] Third, the display component structure, with the cover plate, heat insulation film, and display panel fixed in sequence, improves the convenience of rapid assembly of the display device. Furthermore, the heat insulation film blocks ultraviolet light and the thermal radiation energy of natural light, ensuring the reliability of the display panel in high-temperature outdoor environments.

[0018] Fourth, by designing the protective frame, upper support, and lower support as a single molded structure, the deformation and gaps caused by traditional splicing are avoided, greatly improving the aesthetics of the display device. At the same time, it also provides torsional rigidity and adapts to outdoor vibration environments.

[0019] In summary, this utility model effectively solves the contradiction between high-temperature heat dissipation and waterproof and dustproof sealing of outdoor display devices, as well as the technical problems of numerous assembly processes. It has the advantages of high adaptability to harsh outdoor environments and low operation and maintenance costs.

[0020] 2. In this utility model, a cover plate is used to seal and fix the upper support platform. The upper surface of the cover plate and the upper surface of the protective frame are located on the same horizontal plane, which ensures the consistency and overall aesthetics of the display device.

[0021] 3. In this utility model, the height of the upper support protruding from the inner surface of the frame is less than the height of the lower support protruding from the inner surface of the frame, so as to minimize the black border and improve the aesthetics, thus meeting market demand. The lower support is appropriately widened to enhance the structural strength of the equipment and improve the overall performance, without affecting the appearance of the machine.

[0022] 4. In this utility model, the design of the lower end face of the heat dissipation backplate and the lower end face of the protective frame being on the same horizontal plane further ensures the consistency of the display device and enhances the overall aesthetics of the display device; furthermore, by fixing a waterproof silicone strip between the heat dissipation backplate and the lower support, the mounting surface between the heat dissipation backplate and the protective frame is effectively sealed, enabling the display device to work reliably outdoors for a long time, thereby preventing rainwater or other open water from seeping into the interior of the display device, further improving the waterproof performance and operational stability of the display device.

[0023] 5. In this utility model, by adding heat dissipation fins to the back of the heat dissipation backplate, the heat dissipation surface area on the back of the display device is increased, the natural convection of heat into the air is accelerated, and the operational reliability of the display device is further improved.

[0028] The following will describe the invention in detail with reference to the accompanying drawings and specific embodiments. In this invention, for ease of description, the relative positional relationships of the components are described according to the layout of the accompanying drawings. For example, the positional relationships of front, back, top, bottom, left, right, inside, and outside are determined according to the layout direction of the accompanying drawings.

[0029] This utility model provides an outdoor high-brightness passive heat dissipation waterproof display device, such as... Figure 1-3 As shown, it includes a protective frame 4, a display component and a heat dissipation backplate 6. The protective frame 4 includes a frame body, on which an upper support 401 and a lower support 403 perpendicular to the inner surface are integrally formed. The integrally formed structure of the protective frame 4 is preferably formed by an aluminum extrusion and bending process.

[0030] The display assembly includes a cover plate 2, a heat insulation film 3, and a display panel 1, which are fixed in sequence from the outside to the inside. The cover plate 2 is sealed and fixed on the upper support 401, and the heat dissipation back plate 6 is sealed and fixed on the lower support 403. A passive heat dissipation and waterproof sealed cavity is formed between the display assembly and the heat dissipation back plate 6 through a protective frame 4. The formation of the sealed cavity enables the display device to work normally outdoors, unaffected by harsh environments such as rain, water, and dust, and has strong outdoor adaptability.

[0031] Meanwhile, the heat dissipation backplate 6 is preferably made of aluminum extrusion cutting. The aluminum extrusion heat dissipation backplate is simple to form and can be flexibly customized according to different market needs. The setting of the heat dissipation backplate 6 provides the basic conditions for passive heat dissipation of display devices, avoiding the situation of dust and water entering the device due to the traditional exhaust fan air cooling structure design.

[0032] The display components are fixed in sequence by the cover plate 2, the heat insulation film 3 and the display panel 1, which facilitates the rapid assembly of the display device.

[0033] The heat insulation film 3 can block ultraviolet light and the temperature radiation energy of natural light, ensuring that the display panel 1 can work normally.

[0034] The cover plate 2 is a touch screen, and the upper surface of the touch screen is on the same horizontal plane as the upper surface of the protective frame 4 to ensure the consistency of the display device. Specifically, the touch screen, heat insulation film 3 and display panel 1 are sequentially bonded and fixed. The touch screen and heat insulation film 3 are preferably bonded with water-based adhesive, and then fully bonded to the display panel 1, thus forming a bonding assembly.

[0035] To ensure a reliable seal between the touchscreen and the upper support 401, a composite fixing method combining double-sided adhesive and liquid adhesive is preferred. This combination not only provides strong initial adhesion but also effectively prevents delamination when the device is exposed to high-temperature outdoor operating environments for extended periods, thus ensuring the continuous and stable operation of the device.

[0036] In addition, the cover plate 2 can also be just glass without touch functionality, with the upper surface of the glass and the upper surface of the protective frame 4 on the same horizontal plane to ensure the consistency of the display device.

[0037] Furthermore, the height of the upper bearing platform 401 protruding from the inner surface of the frame is less than the height of the lower bearing platform 403 protruding from the inner surface of the frame.

[0038] like Figure 2-3 As shown, a support hole 405 is provided on the lower support 403, and a back plate hole 601 is provided on the heat dissipation back plate 6. The heat dissipation back plate 6 is fixed on the lower support 403 through the back plate hole 601 and the support hole 405, and the lower end face of the heat dissipation back plate 6 is on the same horizontal plane as the lower end face of the protective frame 4.

[0039] like Figure 1 As shown, a waterproof silicone strip 5 is fixed between the heat dissipation backplate 6 and the lower support 403. The waterproof silicone strip 5 is preferably made of silicone or a material that is resistant to high temperature and aging and can be integrally molded. It can work reliably outdoors for a long time and effectively seal the mounting surface between the heat dissipation backplate 6 and the protective frame 4.

[0040] like Figure 3As shown, multiple protruding heat dissipation fins 602 are evenly fixed on the back of the heat dissipation backplate 6 along its length. Of course, the heat dissipation fins 602 can also be arranged along the width of the heat dissipation backplate 6. By adding heat dissipation fins 602 to the heat dissipation backplate 6, the heat dissipation surface area on the back of the display device is increased, accelerating the natural convection of heat into the air.

[0041] Further reference Figure 3 The heat dissipation backplate 6 also has a cable pass hole 603 and multiple mounting holes 604 in the middle. The mounting holes 604 are evenly distributed around the cable pass hole 603. The cable pass hole 603 can be used to pass through the communication cable connecting the display panel 1 and the user host. The mounting holes 604 are used to install the outdoor display device onto the user-specified bracket or mounting platform.

[0042] The above description is only a specific embodiment of the present utility model. Any feature disclosed in this specification may be replaced by other equivalent or similar features unless otherwise specified. All features or steps in all methods or processes disclosed may be combined in any way except for mutually exclusive features and / or steps.
