Description

A luminous road traffic sign

【Technical Field】

The invention mainly relates to the field of road traffic sign manufacturing, in particular to a luminous road traffic sign.

【Background technique】

With the development of road traffic, the beautification of roads, and the improvement of traffic safety requirements, there are more and more applications of road traffic luminous signs. These luminous road traffic signs can not only serve as a normal indication during the day or a reflective indication at night, and at the same time, when the light source panel emits light at night, the sign panel can also transmit light so that the front side functions as a luminous indication.

In the prior art, luminous road traffic signs include full-transparent area-array luminous signs, semi-transparent area-array luminous signs, and dot-matrix luminous signs. The so-called full-transparent area-array light-emitting sign means that the sign panel is made of fully transparent material, and a light board is set between the back plate and the sign panel (that is, the light-transmitting panel), and the front of the sign panel (that is, the light-transmitting panel) It is equipped with a reflective film with traffic indication graphics and text, which can light up the entire transparent panel when the light board is lit. The so-called semi-transparent area array luminous sign means that the sign panel is made of opaque material (that is, the opaque panel). The front of the opaque panel is provided with a reflective film with traffic indication graphics, but on the opaque panel Corresponding to the traffic indication graphics and text are provided with hollow parts (some are also embedded in the hollow part and then a light-transmitting plate), which makes the light board between the back plate and the opaque panel light through, The hollow part only lights up the graphics and text of the traffic instructions, forming a semi-transparent lighting effect. The so-called dot matrix luminous sign means that the sign panel is made of opaque material, and the front of the opaque panel is provided with a reflective film with traffic indication graphics and text, and then multiple luminous lamp beads are arranged correspondingly according to the traffic indication graphics and text And directly fixed on the opaque panel.

In the prior art, some of the above luminous road traffic signs have the following technical problems:

1. In order to make the logo light up, some battery components are arranged inside the logo (that is, between the back plate and the logo panel), and the battery components are connected to the external solar panels. However, the charging and discharging of battery components have a certain service life (currently 2-3 years), and the traffic signs have a solid structure and installation, and they are erected on a sign pole of a certain height, which makes every 2-3 years The battery components in the logo need to be replaced every year, and the entire logo needs to be removed at high altitude each time, and then the entire back panel is opened for replacement. This not only causes long maintenance work time, heavy maintenance work, and certain operational safety hazards, but also easily damages the sign during the removal and reinstallation process, which seriously increases the operating cost. Moreover, in order to prevent the battery inside the logo from shaking during transportation or installation and causing damage to the internal light board, etc., the battery is generally firmly fixed inside the logo through multiple fixing parts during installation. This fixing method It also increases the difficulty of operations during subsequent replacement, and increases the cost of operation time and labor.

2. Not only safety, but aesthetics is also an important measure of traffic signs. As we all know, as part of urban public facilities, there are a large number of road signs. Therefore, it is necessary to simplify and beautify traffic signs as much as possible so that they will not cause damage to the beauty of the city, the appearance of the city and the environment. And some set a separate battery box on the outside of the sign, which is installed under the sign through the sign pole or directly protrudingly installed on the back plate of the sign, although there is no need to remove the whole sign for battery replacement. However, this structural form is obviously too bloated and has no sense of beauty, and indirectly destroys the beauty of the city.

3. In some signs, an independent solar panel is installed above the sign pole, and the solar panel is electrically connected to the battery in the sign below or in the battery box through a wire. This is further leading to bloated structure and undermining the beauty of the city. Second, the sign pole needs to reserve at least two installation positions for solar panels and traffic signs (some even leave one more installation position for the battery box), and they also need to be installed separately during installation, which makes installation cumbersome and requires a lot of work. The third is that separate solar panels and traffic signs need to be connected by wires, which makes the connection easily affected by wind and sun and short circuit problems, which is inconvenient for maintenance. Fourth, the independent solar panels are prone to bumps and damages during transportation and installation, which will seriously increase operating costs.

4. The existing light signs are generally powered by a single battery. When encountering long-term rainy weather or when the battery has just reached the end of its service life but it is too late to replace, the battery end sign will no longer be illuminated, which will have a serious impact on road safety. Especially when encountering special circumstances (for example, when the local area is heavily foggy and there are many cars, or the signs need to be kept bright for a certain period of time during special services), such non-luminous or dimly lit road signs will have a serious impact.

After being directly inserted into the mounting barrel 61, an electrical connection is formed with the male plug part. The sealing plate 8 can be detachably fixed on the mounting edge 62 by using screws as described below or through waterproof glue.

Through the above special scientific design, it has the following technical advantages:

One is the light-emitting road traffic sign of the present invention, which is provided with a mounting tube 61, which can form a good limit for the battery assembly 5 contained therein, and the battery assembly 5 will not shake during transportation or installation and affect the light-emitting assembly 3 Such damages have greatly improved the safety and stability of the logo. At the same time, this structural form is very convenient for the later maintenance of the battery assembly 5, which can be taken out and inserted very quickly and easily. It takes into account both the stability of the limit and the convenience of disassembly.

The second is the luminous road traffic sign of the present invention. The mounting cylinder 61 is provided with a special mounting edge 62, which has two installation functions. The fixing of the mounting cylinder 61 is completed quickly; at the same time, the installation position of the sealing plate 8 is also assumed, so that the sealing plate 8 after installation can be on the same plane as the frame assembly 1/ or the back plate assembly 4, which greatly improves the overall logo The aesthetics also indirectly improves the beauty of the city. At the same time, because it is in the same plane, rainwater on the frame assembly 1 or the back plate assembly 4 can quickly flow down without forming a gathering at the maintenance port 7 and flowing into the inside of the sign, which greatly improves the safety and service life of the sign.

The third is the special form of cooperation between the installation tube 61 and the maintenance port 7 and the sealing plate 8. It can be based on the specific internal structure of the sign (for example, some transparent signs and semi-transparent signs will have complex light panels and light panels. Support ribs, etc.), and according to the specific form of the external installation pole of the sign (because it is well known that in the prior art, the sign will be installed and fixed by multiple horizontally or longitudinally staggered installation rods and installation components), and flexible replacement, Adjust the opening position of the maintenance port 7 (that is, flexibly replace and adjust the limit position of the battery assembly 5), so that the battery assembly 5 will not hinder other structures inside the logo, and the installation and fixing components outside the logo will not interfere. The battery pack 5 forms a movement hindrance during maintenance.

As shown in Figure 1, Figure 3, Figure 4, Figure 7, further, in a preferred embodiment, the mounting edge 62 is provided with more than two first fixing holes 621 for fixing the mounting cylinder 61 with screws. Fixed on the frame assembly 1/or on the back plate assembly 4, the mounting edge 62 is also provided with two or more second fixing holes 622 for fixing the sealing plate 8 to the mounting edge 62 by screws. The second fixing hole 622 is arranged closer to the edge of the mouth of the mounting cylinder 61 than the first fixing hole 621. Both the first fixing hole 621 and the second fixing hole 622 are provided with internal threads to facilitate the fixing of the screws. This makes installation and maintenance easy and quick. In this embodiment, the contact surface between the sealing plate 8 and the mounting edge 62 is provided with an elastic sealing layer/or an elastic sealing ring (not shown in the figure), which further improves the sealing between the sealing plate 8 and the mounting edge 62 sex.

As shown in Figures 1 to 6, further, in a preferred embodiment, the frame assembly 1 includes a frame plate 11, and a solar panel 9 for supplying power to the battery assembly 5 is fixed on the outer surface of the frame plate 11, and the frame plate 11 is A convex edge 12 is provided on both sides of the axial direction to protect the two sides of the solar panel 9. That is to say, the present invention not only integrates the battery assembly 5 inside the logo, but also integrates the solar panel 9 on the outer side wall of the logo. The bottom of the solar panel 9 is electrically connected to the battery assembly 5 through a wire extending into the logo. In this embodiment, the distance between the two raised edges 12 is just slightly larger than the width of the solar panel 9, that is, the raised edges 12 are arranged close to the sides of the solar panels 9, and the height of the raised edges 12 is not lower than that of the solar panels 9. The thickness of the logo greatly improves the overall aesthetics of the logo. Through the above special scientific design, it has the following technical advantages:

One is the luminous road traffic sign of the present invention, which not only integrates the battery assembly 5 inside the sign, but also integrates the solar panel 9 on the outer side wall of the sign. The integration is greatly improved, not only does not need to reserve solar energy on the sign installation pole The installation position of the board does not protrude from the solar panel set on the top of the sign installation pole, so that the overall structure on the sign installation pole is simple and compact, which greatly improves the overall aesthetics and indirectly improves the aesthetics of the city.

The second is the luminous road traffic sign of the present invention. Since the solar panel 9 is integrated on the sign, there is no need to install the sign and the solar panel separately during installation, which makes the installation convenient and convenient, and the workload is greatly reduced. In addition, the solar panel 9 directly extends into the inside of the sign below and is electrically connected to the battery assembly 5 (equivalent to the hidden wires), no extra wires will appear, which not only further improves the aesthetics, but also improves the stability of the electrical connection.

The third is the luminous road traffic sign of the present invention. Through the special structure of the frame component 1, the first is that the convex edges 12 on both sides will protect the two sides of the solar panel 9 so that the solar panel 9 is not easy to occur during the transportation and installation construction process. The bumps cause damage, which greatly extends the service life; and through the arrangement of the convex edge 12, the solar panel 9 is equivalent to being recessed on the frame assembly 1, which will not form abruptness, which greatly improves the aesthetics of the frame assembly 1, and thus greatly improves The overall aesthetics of the logo is improved.

As shown in Figures 5 and 6, further, in a preferred embodiment, each convex edge 12 is provided with a groove 121 along the axial direction on the side facing the sign box body for connecting the panel assembly 2 and the back The board assembly 4 is respectively clamped and fixed on the frame assembly 1 to form a sign box. By using the thickness of the convex edge 12 itself to open a card slot 121 on its reverse side, this greatly improves the convenience of installation of the sign, and because it is no longer necessary to use other fixing components to fix the panel assembly 2 and the back plate assembly 4, It also greatly reduces the overall weight of the logo.

As shown in Figures 1 to 6, further, in a preferred embodiment, more than one air guide groove 14 is provided on the outer surface of the frame plate 11 to discharge the air in time when the solar panel 9 is glued and fixed. . This enables the solar panel 9 to be firmly fixed on the frame plate 11.

When connected, the end of the frame plate 11 is inserted between the two fixing pieces 131 to be clamped and restricted. And it is fixedly connected to the two fixing pieces 131 by screws. That is, two left and right card slots are formed between the two fixing pieces 131 (as shown at C in FIG. 8). During installation, the end of the frame plate 11 is temporarily restricted after being inserted into the card slot, which makes it possible to further facilitate Subsequent drilling and screw fixation finally form a stable connection. Of course, in other embodiments, if the mark is square, the ends of the two connected frame plates 11 can be welded or fixed by other elbow connectors.

As shown in FIG. 4, further, in a preferred embodiment, a charging plug portion 10 is also provided on the frame assembly 1/or fixed on the back plate assembly 4, and the charging plug portion 10 is located at one end of the sign box for connecting with The battery assembly 5 in the battery limiter 6 is electrically connected, and the other end of the charging plug portion 10 facing outward is used to connect to an external power source to charge the battery assembly 5. In this embodiment, a detachable plastic waterproof cap (not shown in the figure) is also provided at the outer end of the charging plug portion 10, which is used to cover the charging plug portion 10 for protection when it is not charging. By setting the charging plug part 10, the sign is no longer a single power supply mode. When encountering long-term rainy weather or when the battery has just reached the end of its service life but it is too late to be replaced, if the sign needs to be kept illuminated normally, At this time, the battery assembly 5 can be charged through a connection between a wire and an external power source (such as municipal power supply, or with an external power bank, an external generator, etc.), so that the sign can maintain a normal light-emitting indication under special circumstances or special service periods. This greatly improves the practicability and flexibility of use of this sign, which also greatly improves traffic safety.

In this embodiment, the battery assembly 5 includes a battery and a controller. When the solar panel 9 can charge the battery assembly 5, the battery assembly 5 does not supply power to the light-emitting assembly 3; when the solar panel 9 cannot be charged, the light-emitting assembly 3 supplies power to the light-emitting assembly 3 to light up. In another preferred embodiment, the controller is provided with a clock module. For example, if a certain period of time is set to supply power to the light-emitting assembly 3, no matter whether the solar panel 9 can charge the battery assembly 5 during that period of time, the battery assembly 5 Both will supply power to the light-emitting assembly 3. In another preferred embodiment, the sign is provided with a secret service switch connected to the battery assembly 5. When the secret service switch is turned on, whether it is within the time period set by the clock module or whether the solar panel 9 can perform the operation on the battery assembly 5. When charging, the battery assembly 5 will supply power to the light-emitting assembly 3 to keep the sign on. In another preferred embodiment, the battery assembly 5 includes a battery, a controller, and an Internet of Things module with a network to send and receive signals. Through this module, the battery assembly 5 can be remotely controlled to supply power to the light-emitting assembly 3 to keep the sign on.
