Description

The utility model relates to the field of street advertising and can be used to create advertising LED video screens.

Street LED screens are known from the prior art that are assembled from separate modules, each module being sealed and is a finished product. Examples of such systems are described in patents US 8384616 B2 02/26/2013 and US 8172097 B2 05/08/2012. In these patents, the module is a metal case with LEDs located in front, and ventilation holes and a cover for accessing the electronics are located at the back. The module contains a controller inside it that controls the drivers of diodes, boards with soldered diodes, power supplies. Such modules are usually serviced exclusively at the rear, in rare cases, such structures provide front-side maintenance, and there are almost no engineering solutions for servicing the modules at the rear and front. To access the electronics of the module, you must remove the entire module. The inability to maintain the electronics of the screen at the back and front limits the scope of such LED screens. The use of massive metal screen cases also limits the scope of the screens, which does not allow the installation of such screens directly on the walls of buildings.

The main task, which this utility model is aimed at, is to create a street LED screen with easy maintenance at the back and front. In addition, the task of creating a modular scalable design that allows you to assemble solid street LED screens with a working surface of hundreds of square meters is being solved. In addition, the task of significantly reducing the weight of the screen in relation to existing analogues is being solved.

The tasks are solved as follows:

The ability to access the electronics front and rear is achieved using suspended front panels and rear covers with magnetic latches. The rear covers and front panels are hung on the frame using hinged joints, this design allows you to tilt them up and gain access to the screen electronics both front and rear.

The LED screen with two-way maintenance is assembled from segments, each of which consists of a supporting panel and horizontal and vertical profiles fixed to it with bolts. Horizontal profiles have two longitudinal grooves of a circular shape, cylindrical protrusions are provided in the upper part of the front panels and rear covers, which, when inserted into the circular grooves of horizontal profiles, form hinges that allow the rear covers and front panels to be tilted up. The carrier panel has openings for horizontal wire drawing located opposite the openings of vertical profiles. The longitudinal bolt grooves securely fix the bolt head inside the groove, preventing the bolt from rotating. Vertical profiles contain a cavity designed for cable routing.

To create large-sized screens, a system for docking segments together based on finger clips is provided. These clamps are a thick metal sheet of complex shape with metal fingers screwed into the holes. Finger clips are provided for docking segments together and securing segments on a bearing surface. In the vertical profile, longitudinal holes are provided for installing finger clips. These finger clips are set into special holes in the vertical profiles, which allows you to reliably position and fix the segments relative to each other.

Reducing the weight of the screen is achieved through a new approach to the design of the segment housing. Instead of a steel box, a lightweight frame based on a supporting panel is used, which can be made of aluminum or composite sheet, with aluminum profiles fixed to it with bolts. Front panels and rear covers are hung on horizontal aluminum frame profiles, which cover the front and rear openings of the carrier panel and create a moisture-proof space inside the segment.

The front panel is made of plastic with holes for LEDs; an LED module is installed in this panel. To fix the LED modules, one or more plastic clips are used, which are pressed to the front panel with an aluminum tube inserted into the holes on the flanges of the front panels. Magnets are placed on the plastic clips of the front panels, which are attracted to the ferromagnetic plates located on the carrier panel and keep the front panels closed.

Ferromagnetic plates are placed on the rear covers, which are attracted to the magnets located on the carrier panel and keep the rear covers closed. The back covers have one or more ventilation openings. Ventilation grills are inserted into the ventilation openings on the rear covers. On the back covers, a mounting plate is mounted on which the electronic units are mounted. Between the mounting plate and the back cover there is a filter in the form of filter material. Mounting panels are equipped with cooling fans.

A flange is realized at the bottom of the carrier panel, which closes the opening in the lower part of the front panels. Along the perimeter of the screen, edging profiles are installed. An opening for cable pulling is provided inside the edging profile. The edging profile is fixed around the perimeter of the screen with the help of L-shaped and T-shaped plastic elements, which are screwed to the vertical profiles using self-tapping screws.

The two-way LED display screen is structured as follows:

The screen is assembled from segments. The screen segment consists of a frame, which in turn consists of a supporting panel (4), with vertical (2 and 3) and horizontal profiles (1) bolted to it. The carrier panel (4) may be made of aluminum or composite sheet. The vertical and horizontal profiles are connected to the supporting panel by means of a bolted connection (27). The caps of the bolts are inserted into the special grooves of the profiles in such a way that the bolt cannot scroll around its axis or fall out of the groove, after which the profiles are firmly fixed to the surface of the carrier panel with the help of nuts.

The segment housing is formed of 5 basic elements: the carrier panel (4), horizontal profiles (1), vertical profiles (2 and 3), front panels (5), rear covers (6).

Horizontal profiles (1) have a triangular cross-sectional shape. In front of the upper part of the profiles are round longitudinal grooves (11), which, when installing the front panels (5), form hinges for hanging these panels. The same suspension mechanism is implemented for the rear covers (6), for this, a round longitudinal groove (12) is provided at the bottom of the profile, and the rear covers are suspended in the same way as the front panels are suspended. A rectangular groove for inserting the heads of the bolts is provided behind the profile, this groove reliably fixes the cap of the bolt, allowing it to move exclusively along the profile, and does not allow the bolt to scroll around its axis. During assembly, the bolts are inserted into the holes in the carrier panel and nuts are screwed onto them, thus the profile is firmly fixed to the carrier panel.

Vertical profiles (2 and 3) contain cavities (8) designed for pulling cables in the vertical direction. Also, vertical profiles (2 and 3) contain round longitudinal holes (7), which allow you to connect the segments to each other using special finger clips (22). The vertical profile also has longitudinal grooves for inserting the bolt heads. Using these bolts, the profile is securely screwed onto the aluminum sheet.

The front panels (5) are made of plastic, with holes for diodes (28). LED modules are installed in these panels (19). The LED modules (19) rearrange the boards with the light emitting diodes of surface mounting soldered to the surface. The LED modules are fixed on the front panel using plastic clips (18). Plastic clips (18) secure the module to the surface of the front panel, pressing it to it. The latches (18) are held in place by inserting aluminum tubes (23) into the rounded grooves of the latches, which also pass through the holes in the flanges of the front panels (17). The holes (17) allow the tubes to move only in the longitudinal direction, thanks to this, the aluminum tubes (23) reliably hold the clamps in place. Round tabs are provided on the plastic clips, which, falling into special holes in the carrier panel, allow the front panel to be accurately positioned on the surface of the carrier panel and block the movement of the front panels along horizontal profiles. Magnets (29) are mounted on plastic clips using self-tapping screws. Opposite the magnets, plates of ferromagnetic material (30) are mounted on the carrier panel, which form a magnetic latch together with the magnets. A magnetic latch holds the front panels securely closed.

In the upper part of the front panel is a protrusion of a cylindrical shape (9), which forms part of the hinge joint. During the assembly process, the cylindrical protrusions (9) of the front panels are inserted into circular longitudinal grooves (P) in a horizontal profile, which allows you to securely fasten the panel to a horizontal profile and be able to tilt this panel up, rotating around the axis of the hinge joint.

The back cover (6) has a cylindrical protrusion (10) in the upper part, which is inserted into the rear circular round groove of the horizontal profile, thus forming a reliable hinge joint. On the back cover there are holes (14) into which ventilation grilles (15) are inserted, which are used to cool the LED modules. To fix the ventilation grilles, a mounting plate (21) is installed on the rear cover. Between the ventilation grilles and the mounting panel, a filter in the form of filter material (20) can be placed, which prevents dust from entering the segment. Also, cooling fans (13) and various electronic screen units are mounted on the mounting panel. On the back covers with the help of self-tapping screws, plates of ferromagnetic material (30) are installed. Opposite the plates, magnets (29) are mounted on the carrier panel, which form together with the ferromagnetic plates a magnetic latch. The magnetic latch holds the rear covers securely closed.

To form the finished design of the LED screen, edging profiles (24) are used; these profiles have openings for cable pulling inside. Edging profiles are installed around the perimeter of the LED screen and secured with plastic T-shaped (25) and L-shaped (26) elements, which are screwed with self-tapping screws to the vertical profiles.

The screen can be made as follows:

First, horizontal and vertical aluminum profiles are manufactured using an aluminum extrusion operation. Using plastic molding, front panels, rear covers, ventilation grilles and plastic clips are made. The supporting panel can be made of aluminum sheet by laser cutting or stamping, followed by folding the lower flange on a bending machine or press. In the case of the manufacture of a carrier panel of composite material, the holes are made using milling, and the lower flange is bent by milling a longitudinal groove followed by bending of the flange.

The assembly of the segments is as follows:

Vertical and horizontal aluminum profiles are sawn into parts of the desired length. After that, the cylindrical protrusions of the rear covers are inserted into the round grooves of the horizontal profiles, the profiles themselves are screwed to the aluminum sheet using bolt connections. Horizontal profiles are screwed in the same way. Further, the cylindrical protrusions of the front covers are driven into the front round longitudinal grooves of horizontal profiles.

At the next stage, LED modules and plastic clamps are inserted into the front panels. Then, to fix the plastic clips into the side openings of the front panels, aluminum tubes are inserted through the rounded grooves of the plastic clips.

Plastic ventilation grilles are inserted into the rear cover, a filter in the form of filter material is applied to them, the filter material is fixed by pressing the mounting plate, which is screwed to the rear cover with screws. Next, a fan and other electronics are installed on the mounting plate using self-tapping screws.

At the next stage of assembly, all the electronics are interconnected by power and signal wires.

Deployment of the LED screen on the bearing surface is carried out by installing finger clips on the bearing surface, then segments are mounted on the finger clips. A number of segments are fixed on top by installing finger clips. Next, the operation is repeated until the entire screen is deployed on the bearing surface, as the final stage of the screen assembly, edging profiles are installed and fixed using plastic T-shaped and L-shaped elements that are screwed to vertical profiles with screws. Edging profiles are held in place, as they are fixed on both sides by plastic elements that have a protrusion that is inserted into the edging profile.

Maintenance of the LED screen is done by folding the front panels and rear covers up. In this way, technicians can easily access screen electronics.
