[0019] To elaborate on the idea and purpose of the present application, the present application will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above description of the drawings are intended to cover non-exclusive inclusion. The terms "first", "second", "left", "right", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and are not used to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] like Figures 1 to 7 As shown, an embodiment of the present application provides a ventilation and light-tight outdoor grille screen box for a traffic display screen, including an outer frame 10 and a grille structure 20, wherein the outer frame 10 is used to fix the grille structure 20, and the front of the grille structure 20 is used to install a display module 40, and the grille structure 20 includes a light blocking plate 21, and the light blocking plate 21 is recessed inwardly with a plurality of light shields 22, and the lower side wall of the light shield 22 is penetrated by ventilation holes 23.

[0023] like Figures 1 to 7 As shown, the utility model is used to be hung outdoors, such as on an exterior wall or a single column beside a highway, and used as a traffic sign or billboard.

[0024] like Figures 1 to 7 As shown, the outer frame 10 is made of high-strength, corrosion-resistant materials, which can be stainless steel or aluminum alloy. The outer frame 10 should have good waterproof and dustproof properties to ensure that the internal equipment of the outer frame 10 can operate stably in harsh outdoor environments. The shape and size of the outer frame 10 can be customized according to actual needs to adapt to display screens of different specifications and sizes.

[0025] like Figures 1 to 7 As shown, the grille structure 20 is fixed to the front side of the outer frame 10, and the front of the grille structure 20 is used to install the display module 40, and the display module 40 is used for display. Figure 7 The middle arrow indicates the direction of wind flow. When the audience watches the display module 40, the light shield 21 blocks the natural light on the back of the light shield 21 from irradiating the display module 40, reducing the influence of natural light on the display of the display module 40. The wind on the back of the light shield 21 passes through the vents 23 and blows toward the display module 40, which can cool the display module 40 and also reduce the wind resistance of the light shield 21. Since the vents 23 are arranged on the lower side wall of the sunshade 22, the audience looks up or looks straight at the display module 40, and the audience cannot see the natural light irradiated from the vents 23. This solves the influence of natural light on the display from the back of the traditional display screen.

[0026] like Figures 1 to 7 As shown, a heat dissipation structure 30 is disposed on the back of the outer frame 10. The heat dissipation structure 30 is disposed on the back of the grid structure 20 to improve heat dissipation efficiency.

[0027] like Figures 1 to 7As shown, a number of light shields 22 are arranged in an array on the surface of the light baffle 21.

[0028] As Figures 1 to 7 shown, the light shield 22 is a convex structure formed by stamping from the front to the back of the light baffle 21. A ventilation and light-blocking grille structure 20 is provided, and the grille structure 20 is a convex structure punched out by precision machining. The size, shape and arrangement of the light shields 22 can be set as required to achieve the best ventilation and light-shielding properties. The design of the grille structure 20 ensures that while not hindering the heat dissipation of the internal equipment of the present utility model, it effectively blocks the influence of external wind resistance on the present utility model.

[0029] As Figures 1 to 7 shown, the heat dissipation structure 30 is a DC fan. The heat dissipation device can be a heat dissipation port, a DC fan, etc. The position and number of the heat dissipation ports should be reasonably designed according to the heat generation situation of the present utility model and the size of the outer frame 10 to ensure that the heat can be discharged in time.

[0030] The above are the specific implementation manners of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
