Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering, and in particular relates to a portable intelligent prompting device for a highway gantry. Background Art

[0002] Highway gantries are installed in the center of highways and are used for monitoring, inspection, and toll collection. Because they are numerous and cover the entire length of the highway, they are often equipped with electronic devices to provide driving warnings, such as traffic jams and maintenance work ahead, providing convenience for drivers and passengers.

[0003] Common highway gantry prompt devices use fixed information boards. Fixed information boards are fixed above the highway gantry and use network signal lines to transmit display signals. The disadvantages of fixed information boards are as follows:

[0004] (1) The installation of fixed information boards is complicated. If you need to install fixed information boards on the gantry of a highway that has been opened to traffic, you need to close the road for construction and re-lay the network signal lines. Therefore, the installation of fixed information boards is complicated.

[0005] (2) Fixed information boards have high maintenance risks. Fixed information boards are devices fixed to highway gantry, which are usually elevated above the highway pavement. When fixed information boards require maintenance, workers need to work at height on the highway gantry for a long time, which carries a high maintenance risk.

[0006] (3) Temporary deployment of fixed information boards is difficult. On days with heavy traffic, such as holidays, it is usually necessary to provide reminders on multiple highway gantries. Since fixed information boards are not installed on all highway gantries, it is necessary to temporarily deploy currently idle fixed information boards to highway gantries with heavy traffic. However, due to the fixed nature of fixed information boards, temporary disassembly and deployment is difficult or even impossible. Summary of the Invention

[0007] In view of the problems existing in the above-mentioned prior art, the present invention provides a portable intelligent prompt device for highway gantry, and the specific solution is as follows:

[0030] The track housing 12 is mounted on the inner top of the device housing 13 via a rolling shaft 14. The track 11 is sleeved on the track housing 12. Openings 16 are provided on the top of the device housing 13, the track 11, and the track housing 12, respectively. The purpose of the openings 16 is to facilitate the pusher head of the electric push rod 4 to extend out of the track housing 12, the track 11, and the device housing 13 in sequence. The function of the track 11 is to transport the flexible electronic screen 2 to the position of the opening 16 during use and to store the flexible electronic screen 2 back to the bottom of the device housing after use. The electronic screen's rotating shaft 1 is mounted on one end of the track 11 near the opening 16. One end of the flexible electronic screen 2 is mounted on the electronic screen's rotating shaft 1. The electronic screen's rotating shaft 1 functions so that when the control chip 6 sends a signal to the electric push rod driver 8 to extend the electric push rod 4, the slider 3 moves forward along the chute 15, driving the flexible electronic screen 2 to rotate upward along the electronic rotating shaft 1 to a designated position. When the control chip 6 sends a signal to the electric push rod driver 8 to retract the electric push rod 4, the slider 3 moves forward and backward along the chute 15, driving the flexible electronic screen 2 to rotate downward along the electronic rotating shaft 1 to a designated position. A chute 15 is provided at the bottom of the flexible electronic screen 2, and the slider 3 is slidably connected within the chute 15. This converts the linear motion of the electric push rod 4 into rotational motion of the flexible electronic screen 2. A magnet is mounted on the slider 3. The electric push rod 4 is mounted on the side of the device housing 13 opposite the electronic screen's rotating shaft 1, allowing the push rod's head to pass through the opening 16 and be magnetically attracted to the magnet on the slider 3.

[0031] The electric push rod drive 8 is connected to the electric push rod 4, and the motor drive 9 is connected to the track rotation motor 10. The track rotation motor 10 is connected to the rolling shaft 14. The track rotation motor 10 is used to provide rotational motion to the track 11. The flexible electronic screen 2, the electric push rod drive 8, the motor drive 9 and the NBIOT module 5 are respectively connected to the control chip 6, so that the content displayed on the flexible electronic screen 2 is controlled by the control chip 6. The control signal of the electric push rod drive 8 is provided by the control chip 6. The control signal of the electric push rod drive 8 is controlled by the control chip 6. The control signal of the motor drive 9 is provided by the control chip 6. The NBIOT module 5 is used to transmit the display data of the terminal device to the control chip 6, and the control chip 6 displays the data that the terminal device needs to display on the flexible electronic screen 2 through the signal line.

[0032] The power supply 7 provides the operating voltage for the control chip 6. The NBIOT module 5 is connected to a terminal device, which is a mobile phone or a computer.

[0033] Working principle:

[0034] The intelligent prompt device of the above embodiment is fixed on the highway gantry. When not in use, the flexible electronic screen 2 is stored in the bottom of the device shell 13. During operation, the control chip 6 sends a signal to the motor drive 9 to control the track rotation motor 10 to drive the track shell 12 to rotate. The track shell 12 drives the track 11 to rotate. The track 11 drives the flexible electronic screen 2 to rotate, rotating the flexible electronic screen 2 to the opening 16. The control chip 6 also sends a signal to the electric push rod 8 to control the electric push rod 4 to extend. After the push head of the electric push rod 4 is magnetically attracted to the slider 3, it drives the slider 3 to move forward in the slide groove 15, causing the flexible electronic screen 2 to rotate along the electronic screen rotation axis 1 to an upright state. The data to be displayed is then transmitted to the control chip 6 through the terminal device. The control chip 6 then displays the data to be displayed on the flexible electronic screen 2 through the signal line. When the intelligent prompt device does not need to work, the control chip 6 sends a signal to the electric push rod 8 to control the electric push rod 4 to perform a contraction movement. The push head of the electric push rod 4 can drive the slider 3 to move backward in the slide groove 15, so that the flexible electronic screen 2 rotates along the electronic screen rotation axis 1 to a horizontal state. And because the force recovered by the electric push rod 4 is greater than the magnetic force of the magnet on the slider 3, the push head of the electric push rod 4 can leave the slider 3 and complete the contraction action. Then the control chip 6 sends a signal to the motor drive 9 to control the track rotation motor 10 to drive the track 11 to rotate, and rotate the flexible electronic screen 2 to the bottom of the device shell 13.
