Description

Technical Field

[0001] The utility model belongs to the technical field of traffic facilities, in particular to a traffic display screen. Background Art

[0002] Traffic display screens are typically made of LEDs and used for traffic guidance or warning purposes. They are typically used on highways or urban roads. For example, the China Patent Network discloses an outdoor traffic display screen [Authorization Announcement No.: CN204029301U], which consists of a bottom shell, a waterproof ring that fits around the outer periphery of the bottom shell for waterproofing, a PCB board placed on one side of the bottom shell, and a mask that fits the PCB board. The mask is composed of multiple identical units assembled horizontally and vertically. Each unit consists of a bottom plate and side panels perpendicular to the bottom plate plane. The side panels are arranged in an arc-shaped structure. The bottom plate is provided with regularly arranged circular holes. The PCB board is equipped with LED lights as the display light source.

[0003] The above-mentioned outdoor traffic display screen has the following defects: the existing bottom shell is generally made of metal, which makes the traffic display screen heavy, inconvenient to carry, and more laborious to install; secondly, a large waterproof ring is set between the mask and the bottom shell, which increases the difficulty of assembling the traffic display screen on the one hand and increases the manufacturing cost of the traffic display screen on the other hand. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems in the existing technology and propose a traffic display screen. The technical problem to be solved by this utility model is: how to solve the problem that the existing traffic display screen is heavy and inconvenient to carry and install.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] A traffic display screen includes a base shell and a display assembly, wherein the display assembly can display traffic information when lit. The feature is that the base shell is made of plastic, has an installation cavity, and the display assembly is arranged in the installation cavity. The installation cavity has an opening at one end facing the front of the base shell, and a light-transmitting plate is provided on the front of the base shell to block the opening.

[0007] Since the bottom shell is the largest component in the entire traffic display screen, this structure uses plastic to make the bottom shell, which can significantly reduce the weight of the entire traffic display screen, making it easier to carry. Since the traffic display screen is light, it is also more convenient to install. During assembly, the display component is installed into the installation cavity from the front of the bottom shell, which facilitates the assembly of the display component. When the display component is lit, the display component displays traffic information. The setting of the light-transmitting plate, on the one hand, encloses the display component in the installation cavity, playing an isolating and protective role, and on the other hand, enables the traffic information displayed by the display component to be observed by the outside world.

[0008] In the aforementioned traffic display screen, a positioning groove is defined on the front of the bottom shell around the opening, and the light-transmitting plate is embedded in the positioning groove. The positioning groove has a bottom surface, and the back surface of the light-transmitting plate is glued to the bottom surface of the positioning groove. The structure of the light-transmitting plate embedded in the positioning groove enables the light-transmitting plate to be positioned front-to-back and left-to-right, preventing displacement of the light-transmitting plate. The back surface of the light-transmitting plate is glued to the bottom surface of the positioning groove, thereby securing the light-transmitting plate in the positioning groove. This fixing method makes installation of the light-transmitting plate relatively convenient, and the glue also provides a certain waterproof sealing effect, preventing rainwater and dust from entering the installation cavity.

[0009] In the aforementioned traffic display screen, a circle of reflective film is affixed to the front of the bottom shell, and a portion of the reflective film is affixed to the translucent plate. The reflective film covers the joint between the outer edge of the translucent plate and the front of the bottom shell. When light or lamplight shines on the reflective film, the reflective film also reflects light, making the traffic display screen more eye-catching, easily attracting attention, and improving the warning effect. In addition, because the reflective film of this structure is circular, it only covers the joint between the outer edge of the translucent plate and the front of the bottom shell, as well as the surrounding area of ​​the translucent plate, and does not cover the entire translucent plate. This structure allows the outside world to observe the traffic information displayed on the display assembly through the translucent plate, while also further sealing the joint, thereby improving the sealing effect of the joint.

[0010] In the aforementioned traffic display screen, the display assembly includes a PCB board with a plurality of LED lights arranged in an array. A plurality of light-shielding strips are affixed to the front of the light-transmitting plate, each of which is positioned between two adjacent rows of LED lights. The display assembly of this structure utilizes LED lights, which are arranged in an array to facilitate the display of a variety of traffic information, including text or letters such as "Stop" and "P," as well as traffic signs indicating slippery roads in rainy weather and snowy conditions. The light-shielding strips block the blank space between adjacent rows of LED lights, reducing glare on the traffic display screen and increasing the visibility of the traffic information displayed, thereby enhancing the warning effect.

[0011] In the above-mentioned traffic display screen, there are at least two PCB boards, and all the PCB boards are spliced ​​together to form a rectangular shape. Due to the large size of some traffic display screens, multiple PCB boards need to be spliced ​​together to form a display assembly.

[0012] In the aforementioned traffic display screen, a controller and a speed radar are disposed within the mounting cavity, and both the display assembly and the speed radar are electrically connected to the controller. This structure places both the speed radar and controller within the mounting cavity, improving the integration of components within the cavity. Since the mounting cavity is enclosed, it also protects the controller and speed radar. The light-transmitting plate is made of plastic, and the speed radar's detection can penetrate the plastic plate, but not the metal plate. The speed radar in this structure can measure vehicle speed through the light-transmitting plate. The controller transmits speed information to the display assembly, which then displays the speed information.

[0013] In the aforementioned traffic display screen, the bottom shell includes a panel, the outer edge of which extends rearward to form a side frame, the back of the panel has a rearwardly protruding boss, and the front of the panel defines the mounting cavity, which extends into the boss. The bottom shell shape of this structure makes the bottom shell lightweight, has good structural strength, is not easily damaged, and has a long service life.

[0014] In the aforementioned traffic display screen, mounting grooves are formed between the side surfaces of the boss and the inner surfaces of the side frames. Steel frames are embedded in the mounting grooves on the left and right sides of the boss, and the steel frames are riveted to the side frames. Crossbeams are provided between the upper and lower ends of the two steel frames, and each crossbeam is fixedly connected to the two steel frames. The steel frames of this structure are embedded within the bottom shell, and after being riveted to the side frames, the steel frames are fixed to the bottom shell. The two crossbeams are respectively fixedly connected to the two steel frames. The provision of the crossbeams facilitates the installation of the traffic display screen on road pillars. The embedded steel frame structure not only improves the structural strength of the bottom shell, but also improves the convenience of connecting the steel frames to the bottom shell.

[0015] Compared with the prior art, the traffic display screen of the present invention has the following advantages: since the bottom shell is the largest component in the entire traffic display screen, the present structure makes the bottom shell of plastic material, which can significantly reduce the weight of the entire traffic display screen, thereby facilitating transportation. Since the traffic display screen is light in weight, installation is also more convenient. During assembly, the display component is loaded into the installation cavity from the front of the bottom shell, which facilitates the assembly of the display component. When the display component is lit, the display component displays traffic information. The setting of the light-transmitting plate, on the one hand, encloses the display component in the installation cavity, thereby achieving an isolation and protection effect, and on the other hand, enables the traffic information displayed by the display component to be observed by the outside world.

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] Example 1

[0026] like Figures 1 to 6As shown, the present traffic display screen includes a bottom shell 1 and a display assembly 2. The display assembly 2 can display traffic information when illuminated. The bottom shell 1 is made of plastic and has a mounting cavity 3. In this embodiment, the bottom shell 1 includes a panel 100. The outer edge of the panel 100 extends backward to form a side frame 101. The back of the panel 100 has a rearwardly protruding boss 102. The front of the panel 100 is provided with a mounting cavity 3, which extends into the boss 102. The display assembly 2 is disposed in the mounting cavity 3. The mounting cavity 3 has an opening 30 at one end facing the front of the bottom shell 1. A light-transmitting plate 4 is provided on the front of the bottom shell 1 to block the opening 30. A positioning groove 5 is provided on the front of the bottom shell 1 around the opening 30. The light-transmitting plate 4 is embedded in the positioning groove 5. The positioning groove 5 has a bottom surface 50. The back of the light-transmitting plate 4 is glued to the bottom surface 50 of the positioning groove 5. Since the bottom shell 1 is the largest component in the entire traffic display screen, the present structure, by making the bottom shell 1 out of plastic, can significantly reduce the weight of the entire traffic display screen, thereby facilitating transportation. Due to the light weight of the traffic display screen, installation is also more convenient. During assembly, the display assembly 2 is loaded into the installation cavity 3 from the front of the bottom shell 1, facilitating the assembly of the display assembly 2. When the display assembly 2 is illuminated, the display assembly 2 displays traffic information. The provision of the light-transmitting plate 4 not only encloses the display assembly 2 in the installation cavity 3, providing isolation and protection, but also allows the traffic information displayed by the display assembly 2 to be observed from the outside. The structure in which the light-transmitting plate 4 is embedded in the positioning groove 5 achieves front-to-back and left-to-right positioning of the light-transmitting plate 4, preventing the light-transmitting plate 4 from shifting. The back of the light-transmitting plate 4 is glued to the bottom surface of the positioning groove 5, so that the light-transmitting plate 4 is fixed in the positioning groove 5. This fixing method makes the installation of the light-transmitting plate 4 more convenient. At the same time, the glue also has a certain waterproof sealing effect, preventing rainwater and dust from entering the installation cavity 3.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, a reflective film 6 is affixed to the front of the bottom shell 1. The reflective film in this embodiment is black. Part of the reflective film 6 is affixed to the light-transmitting plate 4, and the reflective film 6 covers the joint 7 between the outer edge of the light-transmitting plate 4 and the front of the bottom shell 1. When light or lamplight shines on the reflective film 6, the reflective film 6 also reflects the light, making the traffic display screen more eye-catching, easily attracting attention, and improving the warning effect. In addition, because the reflective film 6 of this structure is circular, the reflective film 6 only covers the joint 7 between the outer edge of the light-transmitting plate 4 and the front of the bottom shell, as well as the surrounding area of ​​the light-transmitting plate 4, and does not cover the entire light-transmitting plate 4. This structure allows the outside world to observe the traffic information displayed on the display assembly 2 through the light-transmitting plate 4, while also further sealing the joint 7, thereby improving the sealing effect of the joint 7.

[0028] like Figure 2 and Figure 4 As shown, the display assembly 2 includes a PCB board 20, on which a plurality of LED lights 21 are distributed in an array. A plurality of shading strips 8 are affixed to the front of the light-transmitting plate 4, and each shading strip 8 is disposed between two adjacent rows of LED lights 21. The display assembly of this structure uses LED lights 21, which are distributed in an array to facilitate the display of a variety of traffic information. That is, they can display text or letter information such as "Stop" and "P", as well as traffic sign information such as slippery roads in rainy days and snowy roads. The shading strips 8 block the blank space between two adjacent rows of LED lights 21, reducing glare on the traffic display screen, making the traffic information more conspicuous when displayed, and thereby improving the warning effect. There are at least two PCB boards 20, and all PCB boards 20 are spliced ​​together to form a rectangular shape.

[0029] like Figure 2 and Figure 4 As shown, a controller 9 and a speed radar 10 are disposed within the mounting cavity 3. The PCB board 20 and the speed radar 10 are both electrically connected to the controller 9. This structure places both the speed radar 10 and the controller 9 within the mounting cavity 3, improving the integration of components within the mounting cavity 3. Since the mounting cavity 3 is enclosed, it also protects the controller 9 and the speed radar 10. The light-transmitting plate 4 is made of plastic, and the speed radar 10 can detect through plastic plates, but not metal plates. In this structure, the speed radar 10 can measure the vehicle's speed through the light-transmitting plate 4. The controller 9 transmits the speed information to the display assembly 2, which then displays the speed information.

[0030] In addition, the traffic display screen can be connected to an external power source, or a battery can be placed in the installation cavity 3 to power the electrical appliances in the installation cavity 3.

[0031] like Figure 7 As shown, a mounting groove 11 is formed between the side surface of the boss 102 and the inner side surface of the side frame 101. Steel frames 12 are embedded in the mounting grooves 11 on the left and right sides of the boss 102. The steel frames 12 are riveted to the side frames 101. A crossbeam 13 is provided between the upper ends and the lower ends of the two steel frames 12. Each crossbeam 13 is fixedly connected to the two steel frames 12. The steel frames 12 of this structure are embedded in the bottom shell 1. After the steel frames 12 are riveted to the side frames 101, the steel frames 12 are fixed to the bottom shell 1. The two crossbeams 13 are fixedly connected to the two steel frames 12 respectively. In this embodiment, the crossbeams 13 are riveted to the steel frames 12. The provision of the crossbeams 13 facilitates the installation of the traffic display screen on the road pillars. The embedded structure of the steel frames 12 provides structural support for the plastic bottom shell 1, which improves the structural strength of the bottom shell 1 on the one hand and the convenience of connecting the steel frames 12 to the bottom shell 1 on the other hand.
