[0002] In road traffic, road information signs display road information for passing motor vehicle drivers to observe, so that they can understand the basic conditions of the road and guide the drivers correctly on the driving route. In order to display more information, electronic information signs are currently used to replace traditional road information signs, which can flexibly change the display content. However, electronic information signs usually need to be used outdoors for a long time, because outdoor factors can easily reduce their service life. For example, dust and rainwater enter, causing the internal electronic structure to not work properly or malfunction, resulting in incomplete road information display.

[0003] In the prior art, a thermally conductive copper sheet is fixed to the rear side wall inside the card box by bolts, and an aluminum heat sink fin passes through a through slot on the rear side of the card box and leaks out of the card box. Thermally conductive silicone grease is provided at the connection between the aluminum heat sink fin and the thermally conductive copper sheet, and the thermally conductive silicone grease is attached to the card box at the edge of the through slot. By providing a through slot on the rear side of the card box, the aluminum heat sink fin on the rear side of the thermally conductive copper sheet passes through the through slot and extends out of the card box, and is fixed with bolts. At this time, the thermally conductive silicone grease is tightly attached to the card box at the edge of the through slot, which can not only conduct heat quickly, but also seal the contact surface between the through slot and the thermally conductive copper sheet, thereby reducing the influence of the external environment on its internal electronic components and isolating the entry of impurities such as dust.

[0004] However, in the above-mentioned prior art, the collar and the column are fixedly installed, and the position of the electronic information board cannot be adjusted, resulting in limitations in use and the inability to change the display angle. Summary of the invention

The block 103 is controlled to move through the telescopic unit and enter the slot 105, so that the ring 102 is fixed on the outside of the column 101, and the position of the electronic display screen 104 is fixed. When the height needs to be adjusted, the block 103 of the upper ring 102 is disengaged from the slot 105, and then the upper lifting unit drives the ring 102 to move downward, and then the upper ring 102 is limited by the block 103. At this time, the lower ring 102 is released from the limit. Since the position of the upper ring 102 is locked, the entire lifting unit moves downward while the upper ring 102 does not move downward, thereby achieving the effect of adjusting the downward movement.

At the same time, the second slider 118 slides in the annular groove 119 to maintain the stability of the rotating plate 117, thereby adjusting the angle of the electronic display screen 104.

[0033] When using an electronic information sign for road information display of the present embodiment, the first motor 108 is started to drive the first rotating shaft 109 to rotate, drive the gear 110 to rotate, and the gear 110 cooperates with the rack 107 to drive the block 103 to move into the slot 105, so that the ring 102 is fixed to the outside of the column 101, and the position of the electronic display screen 104 is fixed. When the height needs to be adjusted, the block 103 of the upper ring 102 is disengaged from the slot 105, and then the upper screw machine 112 is started to drive the first slider 113 to slide in the slide rail 111, so that the ring 102 moves downward, and then the upper ring 102 is re-limited by the block 103. At this time, the lower ring 102 is released from the limit, and the upper screw machine 112 is The lever machine 112 is reversed, so that the upper ring 102 applies an upward force. Since the position of the upper ring 102 is locked, the upper slide rail 111 and the entire lower lifting unit move downward, while the upper ring 102 does not move downward, thereby achieving the effect of adjusting the downward movement.

[0034] In addition, the screen of the electronic display screen 104 is an LED screen, and a networked controller is arranged inside. When the electronic display screen 104 is in use: the staff can input the command to control the electronic display screen 104 through the background. When the time reaches the preset value in the evening, the electronic display screen 104 is adjusted to the night mode, and the screen brightness is automatically lowered. At the same time, a slogan of paying attention to safe driving is displayed to remind the driver to drive carefully at night; when the time reaches the preset value in the morning, the day mode is started, the screen brightness is increased, and more areas of the electronic display screen 104 are mobilized to display road information; when there is rain or snow nearby, the weather conditions can be displayed on the electronic display screen 104 in time through the connection of the networked controller for users to observe. The staff can also change the display color of the information in the background to separate the basic road information and weather information, so that the driver can quickly distinguish them.
