Description

The invention relates to the field of development of auxiliary functional elements of vehicles, in particular to protective sunshields of the control cabin, as well as to devices for the visual display of information, light displays for installation in serial and special vehicles, for example, route, service, etc.

The internal space of vehicles, as a rule, is subject to many design factors: the basic functional diagram, ergonomic standards and safety requirements, as well as the general configuration of the car, taking into account aerodynamics and design. As a result, there is a constant desire to save internal space, optimize all functional elements. Vehicles of certain categories are characterized by universality of applications, for example, minibuses and cars can be used for special needs: transporting passengers, mail, cargo, operated as a taxi, serve as special ambulances or police. In the case of such applications, additional marking is often required, a designation, preferably with highlighted information, to enable recognition of information symbols in the dark. Special signs should also be located in the front of the car, but not obstruct the view from the driver's seat. Finding them inside the car gives the advantage of ease of control directly from the driver's seat and does not violate aerodynamics. One of the functional areas that can be obstructed from the windshield of automobiles is the area covered by sun visors, the geometric dimensions of which, and the installation configuration in vehicles are designed and produced in accordance with technical regulations for viewing angles from the driver's seat according to international standards. At the same time, the sun visor itself can have various stylistic solutions for a specific car. At the same time, route vehicles in particular are described in GOST 25869–90, § 2 “Information support for rolling stock of public passenger land vehicles” and Resolution of the Government of the Russian Federation dated February 14, 2009 N 112 Moscow “On approval Of the Rules for the carriage of passengers and baggage by road and urban surface electric transport ”§ 29-35, that the front direction indicator is located above the windshield of the vehicle and (or) in the upper part of the windshield, where put down the name of the initial and final stopping points and regular transport route number. Based on this information, it can be argued that when placed on a sun visor, the information pointer will not interfere with the driver, in full compliance with the location specified in the regulatory documents. For other vehicle applications, similar placement standards may be used, as they are designed with safety in mind.

The claimed invention is intended to solve the current problem of placing an information light panel in the front of the car without changing the design of the car, the task of saving space in the interior of the car, and the convenience of attaching a light information panel in it, providing quick exposure or hiding the information panel due to the provisions of the sun visor, expanding the functionality of serial cars and applying optimal technological solutions that make up x elements.

Patent documents are known that describe various constructive solutions of sun visors with the possibility of changing and fixing the position in space, containing additional functions and built-in elements.

Similar in design solutions are the following inventions:

U.S. Patent No. US5365416 (A) IPC B60J3 / 02; B60Q3 / 02 of 11/15/1994 describes an anti-sun visor comprising a housing with an internal space, a rotary-locking device provided with an axle and a spring element, designed for rotary connection with a part of the roof of the vehicle cabin, and a plastic core-socket is placed in the internal space for a plastic element, and the configuration of the core is designed to allow extension of the additional plastic element. Also, the design involves the presence of a mirror on the inside of the visor and a backlight towards the interior.

U.S. Patent No. US2007018477 (A1) IPC B60J3 / 00; B60Q3 / 02 dated January 25, 2007 describes a sun visor with a retractable additional part from the middle, for which space and guides are provided in the housing. Inside the housing there is a spring element and an elongated portion of the axis about which the housing rotates.

U.S. Patent No. US6347824 (B1) IPC B60J3 / 02; B60R7 / 05 of 02.19.2002 describes an anti-sun visor comprising a housing with an internal space, a rotary-locking device provided with an axis, intended for rotatable connection with a part of the roof of the vehicle cabin, and also containing an opening compartment in its housing on the rear side for storage of personal items, using part of the hollow interior space of the housing

Known patent RU No. 121203 IPC B60J3 / 02 dated 10/20/2012, comprising a housing made of two permanently connected elements, a rotary-locking device provided with an axis and a spring element made with two opposite sections, each of the housing elements being made of polypropylene and equipped with at least two protrusions with coaxial holes for mounting the axis of the rotary locking device. This patent is taken as a prototype in the type and configuration of the mounting of the rotary-locking device.

Also known are configuration options for light panels, the principle of which is based on the use of light sources placed inside the cases. The front surfaces of light panels are used for applying various information, and reflective and scattering surfaces, transparent plates are used in the construction of buildings.

The information board is known, patent RU No. 162287, IPC G09F13 / 00 dated 06/10/2016, containing a box-shaped housing, a replaceable diffuser cover made of a translucent material with an information field, a linear LED light source with a preferred radiation direction parallel to the plane of the translucent diffuser cover and a reflector located on the inner surface of the housing opposite the translucent diffuser cover, characterized in that the housing along the perimeter of the front edge has an L-shaped profile into which is inserted I, as an easily removable front panel, a structural element, a light-transmitting diffuser cover.

Of the analogues with an attempt to combine the functions of a sun visor and a light panel, a patent is accepted for the closest analogue: patent FR 3026885 (A3), IPC B60Q3 / 04; G09F21 / 04, publ. 04/08/2016. The design described in the patent assumes the presence of a light panel on the inner surface of the visor and options for its extension downward or disclosure in such a way that when the light panel is open, it occupies a place under the anti-sun visor. Obviously, in this position, this panel obstructs the view, violating the permissible viewing angles provided in serial vehicles. Another disadvantage of the analogue is that the light panel that is opened from the inside of the visor as an additional element poses a potential danger to a passenger sitting next to the driver, for example, in case of emergency braking.

The greatest need for a light panel that does not reduce the viewing angles from the driver's seat has route vehicles of category M2, since most of them are serial minibuses with standard, not enlarged, windshield dimensions, do not have routing pointers provided for by the design, and need light signaling symbol of a city route or intercity flight. Due to the fact that one minibus can run periodically in different directions, the light information board should be able to easily replace the front panel with the flight symbol.

This need, as well as the existing need of other mass-produced vehicles, cars and trucks, for an illuminated information panel emphasizes the technical problem, which is the need to provide serial vehicles with a light information panel, preferably a simple, convenient, non-obstructing view and not requiring a change in the design of the vehicle itself facilities. The inventive device is designed to integrate a light bulletin board into an ergonomic design diagram of an already existing interior element of a car’s cabin, such as a sun visor, thereby solving the problem of creating a device combining the functions of a sun visor and a light bulletin board, the configuration of which, based on physical and geometric parameters the most common design of the sun visor, in addition to the function of protection from sunlight, It is expanded to perform the primary function of a light information panel with an easily replaceable front panel, the characteristics of which satisfy, inter alia, the requirements established by the regulatory provisions for information support of route transport. The device should be made in the form of a simple and reliable design, having both light weight and small thickness, shock-absorbing properties of the back surface material, combined with the simplicity and versatility of operation and maintenance of the device in vehicles as an information indicator with an aesthetic and uniform degree of illumination shown on information board, as well as while maintaining the convenience of using the device as an anti-sun visor, not exceeding standard dimensions .

The technical tasks are the integration of the information light panel with the anti-sun visor assembly of a production vehicle while maintaining the viewing angles in the vehicle cabin, increasing the uniformity of illumination of the information symbols of the front panel, improving the usability of the information light panel by providing easy fixation and replacement of the front panel, and, as a result , expanding the functionality of a production car while simplifying the installation, replacement and high-quality illumination of the information panel and due to the implementation of the device’s purpose: exposure of illuminated information in the front of the car without increasing the number of main assembly units of the car’s design and limiting viewing angles from the driver’s position.

The technical result and technical effects are achieved due to the fact that the light information panel with a replaceable front panel, built into the sunshield of the car, has a composite configuration consisting of a supporting lightweight frame with a guide profile, forming together with the replaceable front panel the front and side parts of the body, shock-absorbing rear of the housing, a linear LED source, a button-switch (hereinafter referred to as the button), power wiring and a rotary locking device with a spring element and the additional axis engages. These elements are interconnected by assembly operations, providing constructive unity and implementation by the device of general functional purpose.

The supporting lightweight frame reinforced with stiffeners and having protrusions for attaching a rotary-locking device clamped by a spring element, protrusions with an additional axis of fixation, protrusions for connecting to the rear of the housing, serves to provide rigidity to the entire structure of the device, and also has guide profiles for retraction -extension of the front panel and its fixation in the working position, a hole for placing a button-switch, profiles for placing a linear LED source and ensuring wholesale mal angle light from him.

The upper protrusions of the supporting lightweight frame not only serve as a link for mounting the device, but also set the dimensions of the upper mounting part of the device, setting its size to the distance from the upper part of the front replaceable panel to the axis level of the rotary-fixing device to adapt the inventive device to various vehicles and their configurations cabins in order to ensure a full exposure of the information placed on the front panel in the optically transparent field of the windshield, regardless of where -fiksiruyuschego devices, therefore especially emphasize that the projection height can and should vary in the design of devices for different types of production cars.

The back of the case serves as an impact-absorbing protective, light-blocking element, and the matte white surface treatment material of its internal planes serves as a light-scattering reflector for uniform distribution of the reflected light flux to the replaceable front panel. Since the device has an information function, we mention it as an essential sign that functional and mandatory text labels or information symbols, such as instructions for use, and prescriptive labels for passengers and the driver of the vehicle are placed on the rear of the case from the outside and inside. In particular, from the inside of the rear part of the body, that is, from the side facing in the working position to the glass of the vehicle, information symbols can be placed, which should be visible when the replaceable front panel is removed, thereby eliminating the need for another additional replaceable front panel panels. For example, for fixed-route vehicles, the inscription “to the park” can be permanently placed on the inner surface of the rear of the device. On the outside of the back of the device, for example, a mandatory prescriptive inscription or a “fasten seat belt” sign can be placed. This reference is made taking into account paragraph 37, subparagraph 4 of the Requirements for the description of the invention, (Annex III of the RULES for the compilation, filing and consideration of documents that are the basis for legally significant actions for state registration of inventions, and their form), since these inscriptions are directly related the functioning of the device and the implementation of its direct purpose information board.

The replaceable front panel is light-transmitting and serves to place the main information symbols on it and evenly distribute the light flux from a linear LED source, and can also serve to hide any inscriptions if it is installed upside down with the back side out.

Depending on the type of base, the linear LED source is mounted on the edges of the lower inner surface of the supporting lightweight frame and emits light directed mainly perpendicular to the base and parallel to the plane of the front panel being replaced. The button is used to turn on / off the power of the linear LED source and is connected to the vehicle’s electric circuit with wires going through the rotary-locking device. The rotary-locking device serves to securely fasten the means of a light information board inside the vehicle with a replaceable front panel built into the sunshield using the screw connection of the mount to the corresponding mount socket on the inside of the vehicle’s cabin, as well as to ensure mobility of the rest of the device, and serves to fix the device in the desired position, working or non-working, at the right angle in different planes.

Specialists in the art will be able to offer other options for implementing some of the details of the invention, and changing it in various aspects, without going beyond the essence and scope of the present device. Accordingly, the drawings and a detailed description of the sun visor are illustrative, but not restrictive.

The light information panel with a replaceable front panel integrated into the sunshield of the vehicle contains a lightweight frame 1, which together with the replaceable front panel 2 comprises the front part of the casing and the lower wall 1a reinforced with functional profiles P and the upper wall 1b reinforced with a stiffener B, protrusions 3 s the hollow axis of fixation 3a, the beveled side walls 1b, reinforcing the vertical bridge F, the rear reinforcing wall 1g and, with the aim of allowing replacement and temporary fixation manually of the replacement front panel, the frame has a protruding part 1d with a recess U in the middle and on both sides of it with protrusions 1g, the height of which decreases from the middle to the edges, protrusions 4 having holes 4a from the bottom and coaxial holes 4b from the top for mounting the elongated axis 5 -fixing device and grooves 4g for clamping its spring element 6, and the axis of the rotary-locking device is hollow to conduct electrical wire 7; protrusions 1k and openings 4a for connecting to the second, rear part of the housing 8, made of shock-absorbing material such as semi-rigid polyurethane foam or polypropylene with a lining of energy-absorbing upholstery made of polyvinyl chloride film material; the rear part of the housing 8 has an inner side 8a, beveled starting from the lower third and serving as an internal wall - a reflector for a linear LED source 9 and an outer side 8b, the main plane of which has a small recessed portion of a rectangular shape 10 to accommodate an additional functional element, such as an adapted mirror element , and a field located next to the recess, characterized by a smooth glossy surface in order to increase adhesion, for applying mandatory prescriptive lettering 11 or gluing a film with printed mandatory prescriptive lettering 11. The shape of the rear shock-absorbing part of the housing 8 with its inner side 8a responds in accordance with the shape configuration of the supporting lightweight frame 1 without gaps, with the exception of the recesses in the wiring path 7, and the inner part, where it repeats with the main inclination of the inner plane 8a, the angle of inclination of the side beveled walls 1c of the supporting lightweight frame 1, changing its direction from vertical to inclined, from about one third in height from neither edges, and serves as a diffuse diffuser of light radiation, for which a white light-scattering material M, for example, a matte sticker or paint, is applied to it during molding or after it, over the entire area, and from the place of change of the angle of inclination of the vertical plane, information sign 11a is applied direct printing method, or gluing. The rear part of the housing 8 has recesses on two sides: a recess 12 for supplying the axis of the rotary-locking device, a recess 13 for outputting the axis of fixation, a recess 14 for providing user access to the replaceable front panel 2, a recess-hole 16 for outputting the button 17. Also on the back of the housing 8 has holes 18 with pre-installed washers for mounting to the lightweight supporting frame 1, corresponding to the mounting holes 4a of the lightweight supporting frame 1, the lower profile wall of which is the supporting element for linear light a single-source 9, which, depending on the type of LEDs, is mounted on the edges of the profile P so that the preferred direction of radiation of the light flux goes from bottom to top parallel to the vertical plane of the front surface of the replaced information panel; the front panel is installed and replaced by sliding and sliding along the guides that form the U-shaped profile 19, which is available on at least two sides from the front of the supporting lightweight frame 1: from the upper and lower sides, and from one side - the side of the visor rotary locking device; The U-shaped profile 19 has extensions 20 at the edges to facilitate the end face of the replaceable front panel 2 in the guides of the U-shaped profile 19; also on this side of the supporting lightweight frame 1 there is an opening 21 for the switch 17; the replaceable front panel 2, having a thickness and dimensions corresponding to the internal dimensions of the U-shaped profile 19, is made of light-scattering translucent plastic, or any kind of light-transmitting sheet plastic, including optically transparent and has information symbols 22 on it on one side, printed with using direct printing with UV-curable ink, cutting and applying a PVC film, or in any other way that ensures maximum contrast of characters in relation to the background; an opaque coating 24 is applied to the end part of the side of the front panel, which is in working condition facing the open part of the retaining profile, so that the light does not interfere with the driver, and an additional plastic protector can be installed on at least one side of the replaced front panel vinyl element-flag 25 for more convenient capture and extension of the panel; To correct the strong illumination of the area adjacent to the light source, a translucent gradient mask 23 can be applied from the inside to the front panel using a printing method or any other darkening mask, gradually darkening from the lower edge, providing visual disappearance of the overexposed area on the replaced information panel characters or background from a linear LED source 9 located at the bottom of the supporting lightweight frame 1 and to which the power is supplied by a wire 7 through the plug p 26 from the vehicle electrical circuit; The rotary-locking device has a mount 27 directly to the part of the cab A.

Since the sun visor can be installed in the vehicle cabin on both sides, passenger and driver, symmetrically, it should be obvious to the specialist that the design of the claimed device can be designed and manufactured in two versions, which will be a mirror image of each other, and the configuration of the components parts should also be designed taking into account the specific mounting location: right or left in the cab, while all the components of the device and the principles of their interaction remain They remain unchanged to achieve technical results.

Since the sun visor is a unit of separate or third-party production and is installed after the main assembly of the car, the installation of the inventive device does not require a change in the design of the car itself, and the mount is standard. Power wiring in some cars is already provided for the visors, and is supplied, as can be seen from the description of analogues, for example, to illuminate a mirror built into the anti-sun visor or additional interior illumination.

The claimed invention solves the problem of developing a device that combines the functions of a sun visor and a light information board, the configuration of which, based on the physical and geometric parameters of the most common design of a sun visor, in addition to protection from sunlight, is designed to fulfill the primary function of a light information board, the replaceable front panel of which information carried out in accordance with established regulatory provisions on info transportation support can be easily replaced during operation, while the device is made in the form of a simple and reliable design, having both light weight and small thickness, shock-absorbing properties of the back surface material, combined with the simplicity and versatility of operation and maintenance of the device in vehicles as an information indicator with an aesthetic and uniform degree of illumination displayed on the information panel, as well as while maintaining convenience a device as an anti-sun visor not exceeding standard dimensions.

The technical results of the claimed invention, a light information panel with a replaceable front panel built into the car sun visor, are the integration of the information light panel with the car sun visor unit, and, as a result, the expansion of the serial car’s functionality due to the implementation of the device’s purpose: exposure of the illuminated information in front a car without increasing the number of main assemblies of its design and without limiting viewing angles in Abin. Also, the results are an increase in the uniformity of illumination of the information symbols of the front panel and an increase in the usability of the information light panel by simplifying fixing and replacing the front panel.

The technical effect of increasing the uniformity of illumination of the information symbols of the front panel is manifested due to the implementation of the main supporting frame having a back wall with a height of not more than one fourth of the height of the light information board, adjacent to the side of the linear LED light source, made of dark light-blocking material, together with the peculiarity of changing the angle of inclination the inner plane of the rear of the case with a light-diffusing coating of light tone on it, also due to optimization and the angle of light radiation depending on the type of linear LED source being installed due to special profiles on the lower inner part of the lightweight supporting frame, and due to the application of a gradient mask having a partially light-blocking coating from the lower edge onto the lower part of the front replaceable panel, fading into transparency when moving away from the edge.

The technical effect of simplifying the fixation and replacement of the front panel is manifested due to such design features of the device as the presence of at least two sides, the upper and lower lightweight supporting frame of the U-shaped profile guide, which allows you to push-pull the replaceable front panel, as well as special fixing protrusions from the sides, and from the retraction side - with a recess for grabbing the fingernails of the replaceable front panel, and a protruding flag element, one-piece installed on the side the howling of the replaceable front panel.

Since from the existing level of technology there was no device with a light information board integrated directly into the sun visor in the form of a single, integral and lightweight construction, the claims are presented without division into restrictive and distinctive parts.

The inventive device should serve not only to expand the arsenal of technical means of exposure of illuminated information in the front of the car, but also be the first created technical means of exposure of highlighted information in the front of a serial car, simultaneously without increasing the number of main assembly units of its design and without limiting viewing angles in the cabin, made in the form of a single, integral and lightweight device.

Exercise

The advantage of the proposed device lies in the versatility of the embodiments and assemblies. Component devices can be manufactured industrially and interconnected by various assembly operations: the supporting lightweight frame and the back of the case can be connected by screwing or riveting, as well as by welding or gluing, the rest of the components can be connected by a detachable and one-piece connection, gluing, insertion into sockets with fixation.

The lightweight supporting frame 1 can be made by molding in a mold of dark, lightproof, durable and hard plastic, which is resistant to UV radiation and temperature extremes. Preferred are ABS (acrylbutadiene styrene), PVC (polyvinyl chloride) PLA (polyamide) plastics. Also, the frame can be made of metals by stamping, bending, milling on CNC machines, and other industrial methods. Since the information board in working condition can be in the field of view of the driver of a fixed-route vehicle, its body 8 must be made of light-blocking material and prevent the penetration of light from a radiating source into the vehicle interior. The use of dark-colored plastic for the supporting lightweight frame 1 and its configuration, including protruding edges for fixing the front panel 1zh together with the light-blocking coating 24 of the end face of the replaceable front panel 2, help to ensure light tightness even on the extension side of the replaceable front panel of the device, as well as reduce unnecessary unwanted light reflection inside the information board itself in that part of it that is closest to the linear LED source 9 due to the dark color of the surface behind days reinforcing wall 1g, having a small amount of light reflection. Also, excessive illumination of the part of the replaced front panel 2 closest to the linear LED source 9 is neutralized by a gradient mask 23 applied to the lower part of the back side of the front replaceable panel 2 to increase the uniformity of illumination of information symbols 22.

The replaceable front panel 2 can be made of light-transmitting plastic sheet having a small thickness, resistant to UV radiation and temperature extremes, by simply cutting it to size with the subsequent or previous application of information symbols using cut-out PVC-screen film (polyvinyl chloride) or using gluing films with printing or direct printing, which allows you to use any color combinations that are used for color coding, for example, intracity route boards municipalities, and other standard and customized information tsvetograficheskih circuits. In order to save money, it is possible to recommend a translucent honeycomb polycarbonate 4 mm thick for the manufacture of a replaceable front panel, due to its acceptable physical characteristics and minimal cost in comparison with other materials with the necessary properties. The gradient mask can also be made by direct printing or by printing on an optically transparent self-adhesive polymer / polyvinyl chloride PVC film. The light-blocking coating of the panel end can be made of, for example, high-quality PVC film of black flowers with increased adhesion.

The method of applying information symbols on the replaced front panel to ensure better light distribution can be selected depending on the material of the replaced front panel itself: if the panel material is optically transparent, it would be advisable to apply the printing method on white PVC film for gluing with subsequent gluing. In the case of selecting an optically opaque light-transmitting material of a replaceable front panel, it is possible to apply a printing method on a transparent PVC film or a cut-out of a PVC film followed by gluing, or a direct printing method.

The back of the housing 8, described in the formula as “made of shock-absorbing and light-blocking semi-rigid material”, can be made by molding flexible polyurethane foam or polypropylene with a surface treated with polyvinyl chloride material to achieve shock-absorbing properties and low weight by any of the material options. Also, the necessary inscriptions 11 and 11a can be applied in different ways: both directly in the injection mold, and after molding and surface treatment by screen printing, silk-screen printing or applying stickers. The use of an additional reflective and light-scattering inner coating M of the inner surface 8a of the housing 8 makes it possible to increase the intensity of the reflected light rays on the surface of the replaced front panel 2, including its part that is most distant from the LED source 9, which creates a more uniform illumination of the information symbols of the front panel. The light-scattering coating M on the inner surface 8a of the back of the housing 8 can be performed by applying a glossy or matte light-scattering light tone of the coating with a paint, or a PVC composition, or a self-adhesive PVC film on the inner side of the back of the housing 8. Moreover, the color of the coating can be white and yellow, or others, the main characteristic of which should be light tone - to ensure the reflection of light rays. Since any of these options allows you to achieve the desired effect, in the formula they are indicated by the general concept of "light-scattering coating of light tone". Information symbols can be applied both by the method of cutting out of a PVC film with an adhesive layer and gluing on the surface 8a, and by printing on the whitest glued PVC film.

As a light-emitting source 9, an LED strip is mounted on the lower inner surface of the supporting lightweight frame 1, the optical radiation of which is mainly directed perpendicular to its base, towards the side of the housing having a narrowing. The profile P provided by the configuration of the lower part of the supporting lightweight frame 1 allows the installation of various linear LED sources at optimal angles. As an example, a LED strip with a base width of 0.7 mm, with a self-adhesive base and a frequency of diodes of 120 per meter, suitable for connection to sources with a constant voltage of 12 V, is recommended because of its easy availability in the market, low price and optimal brightness in relation to the price. On one side, the LED source 9 is connected to the button-switch 17, which is connected to the vehicle’s circuit with wires 7 extending in the cavities between the frame and the housing, as well as through the fixing axes 3, axis 5 and the rotary-locking device, via a detachable connection 26 . In those vehicles, the voltage of which differs from 12 V, it is necessary to use the appropriate power supply, placed in the circuit prior to the detachable connection 26, or LED sources of the corresponding voltage.

A gradient mask 23 of the rear surface of the replaceable front panel, having a partially light-blocking coating from the lower edge, smoothly turning into transparency when moving away from the edge, can be created by directly printing on the replaceable front panel 2 gradient black ink with UV-curable ink or by applying a transparent vinyl film with an adhesive layer with an already printed gradient on the bottom of the front replaceable panel 2. The button can be selected from standard on-off switches, with overall dimensions and 15 mm on the large side.

The rotary-locking device with an axis 5 and an attachment unit 27 is a high-strength hollow metal tube of a curved shape with a welded-on or attached method of crimping or flange-type screw attachment, on the one hand, and with an elongated straight section, on the other hand, which is inserted into coaxial the holes of the protrusions 4 and is clamped by a spring element 6, which is a solid piece of sheet material made with two opposite sections and having a U-shaped profile with narrowing kn zu forming shaped wall with a bent lower edge.

The operation of the claimed invention is a light information panel with a replaceable front panel, built into the sun visor of the car - as follows. An information panel with a replaceable front panel integrated into the sun visor can be pre-installed by the vehicle manufacturing plant or can be installed instead of the usual sun visor both from the driver’s side and from the passenger’s side in the vehicle’s cabin at the owner’s request. The replaceable front panel with the necessary information is manually pushed along the guides and fixed in place, which is facilitated by the protrusions and the profile along the edge from the sides of the device frame. Bringing the device into a position close to vertical, the driver enters the information board into the visibility zone outside the vehicle through the glass. By raising to a position close to horizontal, it removes it from the line of sight. In the dark, with the help of a button-switch, the backlight turns on. At the time when the car should be used without any markings, but the light information panel with a replaceable front panel integrated in the sunshield must be in a vertical position to provide the sun protection function, the replaceable front panel is fixed in the information panel with the outside facing out on which information symbols are not visible, or an empty front panel is used. The driver or the conductor may have several standard replaceable faceplates with information symbols printed on them, one of which is fixed in the light information board integrated in the sun visor of the car to indicate, for example, the current route or flight. When it is necessary to replace the front panel, the driver or the service person grabs the edge of the replaced front panel, accessible through the recess, with the fingernails, and extends the panel; also for this, he can take on the protruding plastic element-flag on the replaceable front panel.

In the case when the device is used for displaying information in the vehicle cabin on the right side, that is, on the passenger side, the information panel can be hidden only by bringing it into a horizontal position, since the driver’s function of protection from direct sunlight will perform the same sun visor on the driver’s side, brought into working position at the right angle.

The inventive device, a light information panel with a replaceable front panel, built into the sun visor of the car, is designed to solve the problem of installing route indicators and light information signs in serial cars of any categories, as it has the usual dimensions and physical parameters of the sun visor inside the vehicle, does not require design changes vehicle, but at the same time performs the primary function of exposure of the illuminated information field with the possibility the need to replace information.
