[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6. A smart traffic guidance device for highway toll gates includes a base 1. A sliding sleeve 2 is fixedly connected to the base 1. A support rod 3 is slidably connected inside the sliding sleeve 2. A display screen 6 is mounted on the support rod 3 via an mounting structure 5. The mounting structure 5 includes a support plate 501. The support plate 501 is fixedly connected to the support rod 3. Multiple positioning posts 506 are fixedly connected to the support plate 501. A mounting plate 505 is fixedly connected to the bottom of the display screen 6. Multiple positioning holes 507 are formed on the mounting plate 505. The positioning pin 506 engages with the positioning hole 507. A lead screw 503 is rotatably connected to the support rod 3. A slider 504 is threadedly connected to the lead screw 503. The slider 504 is slidably connected to the support rod 3. A stop plate 502 is fixedly connected to the slider 504. The stop plate 502 abuts against the top of the display screen 6. The end of the support plate 501 has a "U" shaped cross-section. The stop plate 502 has a "U" shaped cross-section. The slider 504 has a "T" shaped cross-section. An adjustment structure 4 is installed on the sliding sleeve 2.

[0024] As a technical optimization of this utility model, rubber pads 12 are installed on both the support plate 501 and the abutment plate 502. Both rubber pads 12 are in contact with the display screen 6. The rubber pads 12 have a "U" shaped structure. The positioning post 506 is perpendicular to the support plate 501. The setting of the two rubber pads 12 increases the friction between the support plate 501, the abutment plate 502 and the display screen 6, thereby making the installation of the display screen 6 more stable and firm.

[0025] As a technical optimization of this utility model, a fixing frame 508 is fixedly connected to the tray 501, and a control box 7 is installed on the fixing frame 508; the control box 7 is installed on the fixing frame 508, and the display screen 6 is controlled through the control box 7.

[0026] As a technical optimization of this utility model, the adjustment structure 4 includes a locking block 401. The locking block 401 is slidably connected to the sliding sleeve 2, and a protrusion 11 is fixedly connected to the support rod 3. The protrusion 11 is slidably connected to the sliding sleeve 2. Multiple slots 402 are equidistantly provided on the protrusion 11, and the locking block 401 engages with the slots 402. A tension spring 404 is fixedly connected between the locking block 401 and the sliding sleeve 2. One end of the tension spring 404 is fixedly connected to the locking block 401, and the other end of the tension spring 404 is fixedly connected to the sliding sleeve 2. When it is necessary to adjust the height of the support rod 3, the locking block 401 is pulled so that the locking block 401 is no longer engaged with the protrusion 11. When the slot 402 on the 11 engages, the locking block 401 drives the tension spring 404 to extend, and then pulls the support rod 3 outward from the sliding sleeve 2. The support rod 3 drives the protrusion 11 to slide inside the sliding sleeve 2. When the support rod 3 is adjusted to a suitable height, the locking block 401 is released. At this time, the tension spring 404 resets and drives the locking block 401 to engage with the slot 402, thereby limiting the protrusion 11 and the support rod 3, and thus quickly adjusting the height of the support rod 3. This allows the vehicle speed feedback device to adjust to a suitable height according to the environment of different sections, which can better remind the driver to slow down in advance. In addition, the setting of the protrusion 11 can prevent the support rod 3 from rotating, thereby increasing the stability of the support rod 3.

[0027] As a technical optimization of this utility model, a guide rod 403 is fixedly connected to the sliding sleeve 2, and the locking block 401 is slidably connected to the guide rod 403; the guide rod 403 has a guiding effect on the locking block 401, making the sliding of the locking block 401 more stable.

[0028] As a technical optimization of this utility model, a connecting rod 8 is fixedly connected to the support rod 3, and a mounting frame 9 is fixedly connected to the connecting rod 8. A solar photovoltaic panel 10 is installed on the mounting frame 9. The solar photovoltaic panel 10 is installed on the mounting frame 9 to provide power to the display screen 6 and the control box 7, so that the vehicle speed feedback device can maintain operation outdoors.

[0029] In use, when the height of the support rod 3 needs to be adjusted, the locking block 401 is pulled, so that the locking block 401 is no longer engaged with the slot 402 on the protrusion 11. At this time, the locking block 401 drives the tension spring 404 to extend, and then pulls the support rod 3 outward of the sliding sleeve 2. The support rod 3 drives the protrusion 11 to slide inside the sliding sleeve 2. When the support rod 3 is adjusted to a suitable height, the locking block 401 is released. At this time, the tension spring 404 resets and drives the locking block 401 to engage with the slot 402, thereby limiting the protrusion 11 and the support rod 3, and thus quickly adjusting the height of the support rod 3. This allows the vehicle speed feedback device to adjust to a suitable height according to the environment of different sections, which can better remind the driver to slow down in advance. The setting of the protrusion 11 can prevent the support rod 3 from rotating, thereby increasing the stability of the support rod 3. The setting of the guide rod 403 has a guiding effect on the locking block 401, making the sliding of the locking block 401 more stable. When installing the display screen 6, the mounting plate 50 at the bottom of the display screen 6 is... Align the mounting plate 505 with the support plate 501, and then place the display screen 6 downwards, so that the positioning hole 507 on the mounting plate 505 engages with the positioning post 506 on the support plate 501, thereby quickly positioning the display screen 6. Then rotate the lead screw 503, and the lead screw 503 thread drives the slider 504 to slide downwards on the support rod 3. The slider 504 drives the abutment plate 502 to slide downwards until the abutment plate 502 presses against the top of the display screen 6, thereby clamping the display screen 6 through the cooperation of the support plate 501 and the abutment plate 502, making the installation of the display screen 6 more convenient and flexible, and the operation simpler. The setting of the two rubber pads 12 increases the friction between the support plate 501, the abutment plate 502 and the display screen 6, thereby making the installation of the display screen 6 more stable and firm. Then install the control box 7 on the fixing frame 508, and control the display screen 6 through the control box 7. Install the solar photovoltaic panel 10 on the mounting frame 9, and provide power to the display screen 6 and the control box 7 through the solar photovoltaic panel 10, so that the vehicle speed feedback device can keep operating outdoors.
