[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] The grille screen has hollowed-out grooves at the front and back, which greatly reduces the wind resistance of the grille screen, so it has excellent wind resistance. Compared with traditional display screens, the grille screen has alleviated the light blocking due to the hollowed-out grooves, and is suitable for building exterior curtain walls. However, in order to ensure the structural strength of the display screen, in the relevant prior art, the number of hollowed-out grooves and the area of ​​the screen body relative to the display screen are relatively small, and the thickness of the bottom shell is relatively thick, resulting in the overall weight not being much lighter than that of conventional display screens, and the ventilation performance is not ideal.

[0029] To this end, the utility model provides a bottom shell that can increase the proportion of the hollowed-out area while ensuring structural strength.

[0030] Reference Figures 1 to 3 As shown, a bottom shell of an embodiment of the utility model comprises: a bottom shell body 100, the bottom shell body 100 is provided with a plurality of hollow structures, and a strip-shaped or grid-shaped support portion 101 is formed by the hollow structures, and a reinforcing rib 105 is provided on the back of the support portion 101 extending backward from the middle position in the width direction thereof. It can be understood that when the hollow structure is strip-shaped, the support portion 101 formed is strip-shaped, and when the hollow structure is circular or rectangular, or a combination of multiple shapes, the support strip formed is a grid-shaped. The reinforcing rib 105 is arranged on the back of the support part 101, which will not hinder the installation and support of the LED panel on the front. At the same time, since the reinforcing rib 105 is arranged in the middle position of the width direction of the support part 101 and extends backward, it will not block the hollow structure. Therefore, the bottom shell in the utility model meets the ventilation requirements of the grille screen by setting a hollow structure, and the support part 101 formed based on the hollow structure can be installed and supported on the front. The reinforcing rib 105 is arranged on the back of the support part 101, so the structural strength can be effectively ensured, and the thickness does not need to be increased, which helps to reduce the weight. In addition, based on the structural reinforcement of the support part 101 by the reinforcing rib 105, the area proportion of the hollow structure relative to the bottom shell body 100 can be increased, thereby improving the wind resistance.

[0031] Considering that in actual applications, LED lamp beads need to be arranged neatly to achieve the required display effect, the setting of the hollow structure needs to make the formed support part 101 meet the installation and support requirements for the LED lamp beads. Therefore, in some embodiments of the present utility model, the hollow structure includes a hollow groove 103, the hollow groove 103 extends in the horizontal direction, and a plurality of hollow grooves 103 are arranged in the vertical direction. The bottom shell body 100 forms a plurality of vertically arranged support parts 101 through the hollow groove 103, and the support part 101 is a horizontally extending strip structure. With the structural setting of this embodiment, a plurality of hollow grooves 103 are arranged in the vertical direction, and each hollow groove 103 extends in the horizontal direction, that is, a horizontally extending and vertically arranged support part 101 is formed, and each support part 101 can be installed to support one or more rows of LED lamp beads, thereby forming neatly arranged LED lamp beads, thereby ensuring the display effect of the grille screen.

[0032] Reference Figure 2 In order to ensure the structural strength of the bottom shell body 100, and further ensure the support stability for the LED lamp beads, and to facilitate the related control connection when installing the LED lamp beads, in some embodiments of the present utility model, the bottom shell body 100 is provided with a plurality of mounting parts 104 along the width direction, the hollow groove 103 is provided between each two adjacent mounting parts 104, and the two ends of the reinforcing rib 105 on the back of each supporting part 101 are connected to the mounting part 104. That is, at least two mounting parts 104 are arranged horizontally and spaced in the bottom shell body 100, and the hollow groove 103 and the supporting part 101 are provided between the two mounting parts 104, so that the structural strength of the bottom shell body 100 can be improved based on the mounting part 104, and the related line connection can be performed from the position of the mounting part 104.

[0033] It is understandable that the mounting portion 104 is a region on the bottom shell body 100 that is divided along the width direction and is not provided with the hollow groove 103. Of course, in order to further improve the structural strength, a reinforcement structure can be further provided on the mounting portion 104.

[0034] Reference Figure 2 In some embodiments of the utility model, the back of the support portion 101 is provided with transition slopes 1011 or transition arcs at both ends. Since the hollow groove 103 is used to reduce wind resistance, this embodiment is conducive to the wind from the back passing through the front by providing transition slopes 1011 or transition arcs at both ends of the back of the support portion 101. When the wind from the front passes through the hollow groove 103 and blows toward the back, the width of the hollow groove 103 increases based on the transition slope 1011 or transition arc, so the wind speed and wind pressure are relieved, which can reduce the force on the bottom shell body 100, thereby improving the wind resistance.

[0035] In some embodiments of the present invention, the reinforcing rib 105 is located between the transition slope 1011 or the transition arc surface. With the structural arrangement of this embodiment, the reinforcing rib 105 can improve the structural strength of the support portion 101 while also being able to cooperate with the transition slope 1011 or the transition arc surface to guide the wind direction, thereby improving the wind passing efficiency and thus improving the wind resistance performance.

[0036] Reference Figure 1 In some embodiments of the present invention, a plurality of connecting ribs 102 are provided in the hollow groove 103, and the connecting ribs 102 are connected to two adjacent support portions 101. It is understandable that in the length direction of the hollow groove 103, the strength between the support portions 101 will be weaker than that at both ends. In this embodiment, the connecting ribs 102 are provided to connect the two adjacent support portions 101, which can effectively improve the overall structural strength of the bottom shell body 100.

[0037] Reference Figure 3 In order to achieve the installation and fixation of the LED lamp beads, in some embodiments of the present invention, a positioning recess is provided on the front of each support portion 101 and the front of each mounting portion 104, and the positioning recesses are interconnected to accommodate the LED light board 200. Since the LED lamp beads are fixed on the LED light board 200, to achieve the installation and fixation of the LED lamp beads on the bottom shell, it is only necessary to carry out structural design and installation corresponding to the LED light board 200. This embodiment accommodates the LED light board 200 by setting a positioning recess, which can not only support the LED light board 200, but also limit the position of the LED light board 200. And on this basis, it is only necessary to install the mask 300 or set screws for fixing.

[0038] Reference Figure 3 , combined with the description of the above-mentioned embodiments, it can be known that the strength of the support portion 101 in the length direction will be weaker than the structural strength at the end position. If a positioning recess is set, the strength will be further reduced. For this reason, in some embodiments of the utility model, the support portion 101 is formed with two upper and lower limiting walls 1012 through the positioning recess, and the connecting rib 102 is provided on the limiting wall 1012. In this way, the side wall of the positioning recess can be structurally strengthened by the connecting rib 102. It can be understood that the size of the positioning recess is preferably adapted to the size of the LED light board 200, so that when the LED light board 200 is embedded in the positioning recess, it fills the positioning recess, which is conducive to ensuring the overall structural strength.

[0039] In addition, the utility model also proposes a grille screen, including a bottom shell and an LED panel, the bottom shell is provided with a bottom shell body 100, the bottom shell body 100 is provided with a plurality of hollow structures, and a strip-shaped or grid-shaped support portion 101 is formed by the hollow structure, and a reinforcing rib 105 is provided on the back of the support portion 101 extending backward from the middle position in the width direction of the support portion 101; the LED panel is provided at the front end of the bottom shell body 100. It can be understood that the grille screen in the utility model meets the ventilation requirements of the grille screen by providing a hollow structure on the bottom shell body 100, and the front side of the support portion 101 formed based on the hollow structure can be installed and supported by the LED panel, and since the back side of the support portion 101 is provided with a reinforcing rib 105, the structural strength can be effectively ensured, and the thickness does not need to be increased, which helps to reduce the weight. In addition, based on the structural reinforcement of the support portion 101 by the reinforcing rib 105, the area proportion of the hollow structure relative to the bottom shell body 100 can be increased, thereby improving the wind resistance performance.

[0040] Specifically, in some embodiments of the present invention, the hollow structure includes a hollow groove 103, the hollow groove 103 extends in the horizontal direction, and a plurality of hollow grooves 103 are arranged in the vertical direction, the bottom shell body 100 forms a plurality of vertically arranged support parts 101 through the hollow groove 103, and the support parts 101 are in a horizontally extending strip structure; a positioning recess is provided on the front of the support part 101; the LED panel includes an LED light board 200 and a mask 300, the LED light board 200 is installed in the positioning recess, and the mask 300 is buckled with the bottom shell body 100 on the front of the LED light board 200. The LED light board 200 is accommodated by the positioning recess, and then the mask 300 is covered and limited, which can ensure the installation stability of the LED light board 200 and facilitate disassembly and assembly.

[0041] Reference Figures 1 to 3In some embodiments of the present invention, the grille screen includes a bottom shell and an LED panel, wherein the bottom shell includes a bottom shell body 100, and the LED panel includes an LED light board 200 and a mask 300. Specifically, the bottom shell body 100 is divided into three mounting parts 104 of left, middle and right in the horizontal direction, and between two adjacent mounting parts 104, the bottom shell body 100 is provided with a plurality of hollow grooves 103 in the vertical direction, and each hollow groove 103 extends in the horizontal direction, so that a plurality of support parts 101 distributed in the vertical direction are formed between the two mounting parts 104. The front of the mounting part 104 and the support part 101 is concavely provided with a positioning recess, and the overall shape, size and contour of the positioning recess are consistent with the LED light board 200. The support part 101 is formed with two upper and lower limiting walls 1012 corresponding to the positioning recess, and between the two adjacent support parts 101, a connecting rib 102 connecting the limiting walls 1012 is provided, so as to improve the structural strength of the support part 101 through the connecting rib 102. And along the left and right directions, a plurality of connecting ribs 102 are connected to the support portion 101. Transition slopes 1011 are provided at the upper and lower ends of the back of the support portion 101, and reinforcing ribs 105 are provided extending backward between the two transition slopes 1011. The left and right ends of the reinforcing ribs 105 are connected to the mounting portion 104. The LED light board 200 is embedded in the positioning recess. The mask 300 is provided with buckle feet matching the connecting ribs 102, which buckle the connecting ribs 102 from the front of the bottom shell body 100 and press the LED light board 200. At the same time, the four top corners of the mask 300 also have screws that pass through the LED light board 200 and directly connect to the bottom shell body 100.

[0042] It is understandable that, since the wind force acts mainly in the front-to-back direction, the grille screen in this embodiment can effectively improve the wind resistance by setting the reinforcing ribs 105 on the back of the bottom shell body 100, without increasing the overall thickness of the bottom shell body 100, so the weight can be reduced. In addition, the transition slope 1011 is set based on the reinforcing ribs 105 to guide the wind. The connecting ribs 102 are connected between the limiting walls 1012, which can improve the structural strength of the support part 101. Comprehensively combining all the settings, the area ratio of the hollow groove 103 can be increased to the maximum extent, and the wind resistance can be improved.

[0043] The present invention is described in detail above in conjunction with the embodiments, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
