Description

Technical Field

[0001] The present invention relates to the field of LED advertising screens, and particularly to an intelligent advertising screen for outdoor use. Background Art

[0002] Traditional LED advertising screens have obvious defects when facing strong wind weather. The windward area of the LED advertising screen is large and the center of gravity is relatively high, resulting in weak wind resistance. It is prone to problems such as tipping and component damage in strong winds, affecting the normal use and safety of the advertising screen.

[0003] In summary, we propose an intelligent advertising screen for outdoor use. Summary of the Invention

[0004] In order to overcome the disadvantages that the LED advertising screen has a large windward area and a relatively high center of gravity when facing strong wind weather in the prior art, resulting in weak wind resistance, the present invention provides an intelligent advertising screen for outdoor use, including a bottom support member, a column, a first electric slider, a connecting member, and an LED display module.

[0005] A plurality of columns are fixedly connected to the bottom support member; a plurality of first electric sliders are slidably connected to each column; a connecting member is fixedly connected to the first electric slider; an LED display module is rotatably connected to the connecting member, and the LED display module can be rotated and adjusted between a horizontal state and a vertical state; by rotating the LED display module to the horizontal state, and then the first electric slider drives the LED display module in the horizontal state to move downward, so that the center of gravity of the advertising screen moves downward and the windward area is reduced.

[0006] Furthermore, no connecting rod is provided between the columns, so the amount of debris hanging on the columns when blown by strong wind can be reduced.

[0007] Furthermore, the bottom support member is a bottom plate.

[0008] Furthermore, it further includes a protective housing, which is composed of a left housing and a right housing; a horizontal moving component is installed on the bottom support member, the left moving part of the horizontal moving component is fixedly connected to the left housing, and the right moving part of the horizontal moving component is fixedly connected to the right housing; the LED display module is protected by the protective housing.

[0009] Furthermore, it further includes a top protective cover, and the column is connected to the top protective cover through a second electric slider; when the second electric slider moves up and down on the column, it drives the top protective cover to move up and down.

[0010] Furthermore, an elastic sponge is installed on the upper side of the second electric slider to wrap the column.

[0011] Furthermore, the horizontal movement component includes a connecting block, a horizontal guide rail, a third electric slider, and a sliding strip; the bottom of the bottom support member is connected with a horizontal guide rail through a plurality of connecting blocks, two third electric sliders are slidably connected to the middle of the horizontal guide rail, one third electric slider is fixedly connected to the left housing, and the other third electric slider is fixedly connected to the right housing; a sliding strip is fixedly connected to each of the left housing and the right housing, and the sliding strip slides on the horizontal guide rail.

[0012] Furthermore, it further includes an inclined guide rail, a fourth electric slider, and a cleaning brush; an inclined guide rail is installed on the upper part inside each of the left housing and the right housing; a fourth electric slider is slidably connected to the inclined guide rail; the cleaning brush is detachably connected to the fourth electric slider, and the LED display module is cleaned by the cleaning brush.

[0013] Furthermore, the upper inner wall of the left housing is inclined to the left, and the upper inner wall of the right housing is inclined to the right.

[0014] Furthermore, the cleaning brush is supplied with water through a water supply system.

[0015] The present invention has the following advantages:

[0016] The wind resistance performance is significantly enhanced: by rotating the LED display module to the horizontal state and moving it downward, the center of gravity of the advertising screen can be effectively reduced, and the windward area can be reduced. Specifically, the center of gravity of the advertising screen can be moved downward, greatly improving the wind resistance ability and reducing the risk of tipping or damage in strong wind weather. At the same time, no connecting rod is provided between the columns, which can reduce the amount of debris hanging on the wind during strong wind blowing, further optimizing the wind resistance effect.

[0017] The protection function is comprehensively improved: a protective housing composed of a left housing and a right housing is provided. Before strong wind comes, the left and right housings can be separated through the horizontal movement component, and after the LED display module moves downward to the protection area, it can be reset, effectively avoiding the pollution or damage of the LED display module by debris in the wind. The top protective cover can move up and down under the drive of the second electric slider, which can not only cover the top docking part of the protective housing, but also separate the debris hanging on the column by using elastic sponge, preventing the debris from damaging the advertising screen.

[0018] It has an automatic cleaning function: an inclined guide rail, a fourth electric slider and a cleaning brush are installed on the upper part inside the left and right housings. During daily use, the LED display module can be controlled to be in an inclined state and in contact with the cleaning brush. The fourth electric slider drives the cleaning brush to reciprocate on the inclined guide rail, and combined with the water supply of the water supply system, the surface of the LED display module can be automatically cleaned. The sewage can be discharged from the sewage outlet of the bottom support member, ensuring that the advertising screen can still maintain a good advertising display effect in an environment with a large amount of dust.

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0030] Example 1

[0031] An intelligent advertising screen for outdoor use, as Figures 1-9 shown, includes a bottom support member 1, a column 2, a first electric slider 3, a connecting member 4 and an LED display module 5;

[0032] A number of columns 2 are fixedly connected to the bottom support 1, and the columns 2 are arranged parallel to each other; a plurality of first electric sliders 3 are slidably connected to each column 2; a connecting member 4 is fixedly connected to the first electric slider 3; an LED display module 5 is rotatably connected to the connecting member 4, and the LED display module 5 can be rotated and adjusted between a horizontal state and a vertical state. For example, the connecting member 4 is rotatably connected to the LED display module 5 through a rotating shaft, and a motor is provided at one end of the rotating shaft to drive the rotating shaft to rotate; by rotating the LED display module 5 to the horizontal state, and then the first electric slider 3 drives the LED display module 5 in the horizontal state to move downward, so that the center of gravity of the advertising screen moves downward and the windward area is reduced.

[0033] In order to overcome the problems in the prior art that when the LED advertising screen faces strong wind weather, the windward area of the LED advertising screen is large and the center of gravity is relatively high, resulting in weak wind resistance, the following solutions are proposed in the present invention;

[0034] When the present invention works in strong wind weather, the wind shelter mode of the present invention can be automatically started through the wind sensor provided on the advertising screen or manually activated.

[0035] The wind shelter mode is as follows:

[0036] First, rotate the LED display module 5 to the horizontal state, and then control the first electric slider 3 to move downward actively on the column 2, so that the LED display module 5 in the horizontal state moves to the lower part, presenting Figure 3 to Figure 5 the state change; in this way, through the downward movement of the LED display module 5, the center of gravity of the advertising screen moves downward, and at the same time, only the column 2 is exposed to reduce the windward area of the advertising screen.

[0037] It should be noted that, as Figure 3 shown, the advertising content of the present invention is displayed by combining a plurality of LED display modules 5 in the vertical state.

[0038] In the embodiment of the present invention, no connecting rod is provided between the columns 2, so the amount of sundries hanging on the columns 2 when blown by strong wind can be reduced.

[0039] In the embodiment of the present invention, the bottom support 1 is a bottom plate, and the bottom plate has a large contact area with the ground, providing better supporting force and anti-tipping force.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, as Figures 1-9As shown in the figure, it further includes a protective housing 101, which is composed of a left cover and a right cover; a horizontal movement component is installed on the bottom support 1, the left moving part of the horizontal movement component is fixedly connected to the left cover, and the right moving part of the horizontal movement component is fixedly connected to the right cover. By driving the left cover and the right cover to move through the horizontal movement component, the disassembly and docking of the protective housing 101 are realized; the LED display module 5 is protected by the protective housing 101.

[0042] It further includes a top protective cover 102, and the column 2 is connected to the top protective cover 102 through a second electric slider 1021; when the second electric slider 1021 moves up and down on the column 2, it drives the top protective cover 102 to move up and down.

[0043] An elastic sponge is installed on the upper side of the second electric slider 1021, and the elastic sponge is not shown in the figure. The column 2 is wrapped by the elastic sponge.

[0044] The horizontal movement component includes a connecting block 103, a horizontal guide rail 104, a third electric slider 105 and a sliding strip 106; the bottom of the bottom support 1 is connected to the horizontal guide rail 104 through a plurality of connecting blocks 103, two third electric sliders 105 are slidably connected to the middle of the horizontal guide rail 104, one third electric slider 105 is fixedly connected to the left cover, and the other third electric slider 105 is fixedly connected to the right cover; a sliding strip 106 is fixedly connected to each of the left cover and the right cover, and the sliding strip 106 slides on the horizontal guide rail 104.

[0045] Considering that in strong wind conditions, there will be sundries (such as dust, plastic bags, particulate matter, etc.) carried in the wind. If the sundries are blown onto the LED display module 5, it will cause the LED display module 5 to be soiled or damaged. To solve this problem, before the LED display module 5 moves down, the left cover is first driven to move left and the right cover is driven to move right by two third electric sliders 105, presenting Figure 8 to Figure 9 the state change, so as not to block the downward movement of the LED display module 5. Then the LED display module 5 moves down to the protection area of the left cover and the right cover, and then the left cover and the right cover are controlled to reset, presenting Figure 9 to Figure 8 the state change, thereby realizing the protection of the LED display module 5 by the protective housing 101 and avoiding the pollution or damage of the LED display module 5 by sundries in the wind. Further, the second electric slider 1021 can be controlled to drive the top protective cover 102 to move downwards, so that the top protective cover 102 covers the docking part at the top of the left cover and the right cover to protect the docking part.

[0046] It should be noted that there are strip-shaped or block-shaped sundries such as plastic bags in the wind. When they come into contact with the column 2, they may hang on the column 2. To solve this problem, when the wind stops, the present invention can drive the top protective cover 102 to move upward by the second electric slider 1021, and use the top protective cover 102, the second electric slider 1021, and the elastic sponge on the upper side of the second electric slider 1021 to separate the sundries hanging on the column 2, and then the sundries fall downward from the inclined surface of the top protective cover 102.

[0047] Embodiment 3

[0048] On the basis of Embodiment 2, as Figures 1-9 shown, it further includes an inclined guide rail 201, a fourth electric slider 202, and a cleaning brush 203; an inclined guide rail 201 is installed on the upper part of each of the left housing and the right housing; the fourth electric slider 202 is slidably connected to the inclined guide rail 201; the cleaning brush 203 is detachably connected to the fourth electric slider 202, and the LED display module 5 is cleaned by the cleaning brush 203.

[0049] The upper inner wall of the left housing is inclined to the left, and the upper inner wall of the right housing is inclined to the right.

[0050] The cleaning brush 203 is supplied with water through a water supply system (not shown in the figure as it is a prior art and will not be elaborated here).

[0051] Furthermore, considering that dust will adhere to the surface of the LED display module 5 during daily use, affecting the advertising display effect; to solve this problem, the present invention can control the LED display module 5 to be inclined and move downward to Figure 8 the state shown, at this time, the uppermost LED display module 5 comes into contact with the cleaning brush 203, so that the fourth electric slider 202 can be controlled to reciprocate on the inclined guide rail 201, thereby driving the cleaning brush 203 to reciprocate to clean the surface of the LED display module 5. At the same time, the cleaning brush 203 is supplied with water through the water supply system to improve the cleaning effect, and the sewage is discharged from the sewage outlet 101a of the bottom support 1. The inclined LED display module 5 is also conducive to the drainage of sewage; further, when the uppermost LED display module 5 is cleaned, the present invention is controlled to be in Figure 9 the state shown, and then the uppermost LED display module 5 is controlled to move upward to reset, and then the remaining LED display modules 5 are sequentially cleaned from top to bottom in the same cleaning operation, thus realizing the automatic cleaning of the LED display module 5 and ensuring the advertising display effect of the present invention in an environment with a large amount of dust.

[0052] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
