Description

Technical Field

[0001] This utility model relates to the field of display screens, and in particular to a passenger information display screen for rail transit. Background Technology

[0002] During rail transit operations, passenger information display screens serve as crucial equipment for conveying key information such as train numbers, stations, times, and emergency notices to passengers. Their effectiveness directly impacts passengers' travel experience and information acquisition efficiency. Due to the high volume of people moving around in rail transit environments, dust and dirt in the air easily adhere to the surface of the display screens. Over time, this accumulation leads to a decrease in screen clarity, affecting passengers' ability to recognize information. Traditional display screens generally lack dedicated cleaning components, requiring operators to use external cleaning tools for wiping. This is not only inconvenient but also prone to scratching the screen during cleaning. Furthermore, some cleaning components are difficult to install and disassemble, and cleaning cloths are hard to replace, resulting in low cleaning and maintenance efficiency and increasing the workload of staff.

[0003] To address the aforementioned problems, this utility model proposes a clean and easy-to-maintain passenger information display screen for rail transit. Utility Model Content

[0004] The main purpose of this utility model is to propose a rail transit passenger information display screen, which aims to solve the problem that existing rail transit passenger information display screens are inconvenient to clean and maintain.

[0005] To address the aforementioned problems, this utility model proposes a rail transit passenger information display screen, comprising: a support base, a support plate fixedly connected to the upper end of the support base, a fixing plate fixedly connected to the front side of the upper end of the support plate, a screw rotatably connected to the left side of the fixing plate near the support base, the upper end of the screw penetrating the fixing plate, a servo motor connected to the upper end of the screw, the servo motor being electrically connected to a power source via a power cable, and the servo motor being fixedly connected to the fixing plate, a guide rod rotatably connected to the right side of the fixing plate near the support base, a connecting plate slidably connected to the outside of the guide rod, and the connecting plate being threadedly connected to the screw, a display screen body connected to the front end of the connecting plate, and a cleaning component provided at the front end of the display screen body.

[0006] In one embodiment, the cleaning component includes a card plate, with card plates fixedly connected to both the left and right ends of the display body, and sliding grooves provided at the far ends of the two card plates.

[0007] In one embodiment, a sliding block is slidably connected inside each of the two sliding grooves, and a rotating shaft is rotatably connected inside the two sliding blocks at their far ends.

[0008] In one embodiment, two sliding plates are provided on the outer side of the two rotating shafts at opposite ends, and the rear ends of the two sliding plates are provided with through slots. Limiting rods are fixedly connected inside the two slots.

[0009] In one embodiment, two limiting rods pass through two rotating shafts from front to back, and compression springs are sleeved on the outer side of the rear end of each limiting rod.

[0010] In one embodiment, mounting plates are fixedly connected to the front sides of the two adjacent sliding plates, push-pull handles are fixedly connected to the middle of the front ends of the two mounting plates, and threaded plates are fixedly connected to the front sides of the two adjacent mounting plates.

[0011] In one embodiment, the two threaded plates are internally threaded with tightening screws, and the tightening screws pass through the two threaded plates from both sides.

[0012] In one embodiment, each of the two mounting plates has a mounting groove at its rear end, a cleaning plate is slidably connected inside the two mounting grooves, and a cleaning cloth is wrapped around the outside of the cleaning plate.

[0013] Beneficial effects:

[0014] 1. By using a servo motor to drive the screw to rotate, the connecting plate is moved up and down steadily along the guide rod, thereby adjusting the height of the main body of the display screen. This allows for convenient and stable adjustment of the display screen height according to actual usage needs, meeting the information viewing needs of passengers in different scenarios. Furthermore, the servo motor is fixedly connected to the fixed plate, ensuring the stability of the drive structure.

[0015] 2. The sliding plate can move laterally within the sliding groove of the card plate via the sliding block, thereby driving the cleaning plate to move laterally to clean the display screen body. At the same time, the cooperation between the rotating shaft and the limiting rod, as well as the compression spring sleeved at the rear end of the limiting rod, provides a certain buffer and reset capability for the movement of the sliding plate, ensuring that the cleaning plate can maintain proper contact with the surface of the display screen during the cleaning process.

[0016] 3. The two mounting plates can be easily assembled and disassembled, facilitating the maintenance and replacement of cleaning components. At the same time, a cleaning plate wrapped with an external cleaning cloth is slidably connected in the mounting groove at the rear of the mounting plate. This design not only facilitates the installation, replacement and cleaning of the cleaning cloth, but also ensures the cleaning effect of the cleaning cloth, thereby ensuring the cleaning quality of the display screen body.

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.

[0026] To achieve the above-mentioned utility model objectives, such as Figure 1-5 As shown, this utility model provides a passenger information display screen for rail transit, including: a support base 1, a support plate 2 fixedly connected to the upper end of the support base 1, a fixing plate 3 fixedly connected to the front side of the upper end of the support plate 2, a screw 4 rotatably connected to the left side of the fixing plate 3 near the support base 1, and the upper end of the screw 4 passing through the fixing plate 3, a servo motor 5 connected to the upper end of the screw 4, the servo motor 5 being electrically connected to a power source via a power cord, and the servo motor 5 being fixedly connected to the fixing plate 3, a guide rod 6 rotatably connected to the right side of the fixing plate 3 near the support base 1, a connecting plate 7 slidably connected to the outside of the guide rod 6, and the connecting plate 7 being threadedly connected to the screw 4, a display screen body 8 connected to the front end of the connecting plate 7, and a cleaning component provided at the front end of the display screen body 8.

[0027] Preferred, such as Figure 4 As shown and Figure 5 As shown, the cleaning component includes a card plate 9. Card plates 9 are fixedly connected to both the left and right ends of the display screen body 8. Sliding grooves 10 are opened at the far ends of the two card plates 9. Sliding blocks 11 are slidably connected inside the two sliding grooves 10. Rotating shafts 12 are rotatably connected inside the far ends of the two sliding blocks 11.

[0028] Preferred, such as Figure 5 As shown, each of the two rotating shafts 12 has a sliding plate 13 on its outer side at the far end. Each of the two sliding plates 13 has a through slot 14 at its rear end. Each of the two slots 14 has a fixedly connected limit rod 15 inside. The two limit rods 15 pass through the two rotating shafts 12 at the front and rear respectively. Each of the two limit rods 15 has a compression spring 16 sleeved on its outer side at the rear end.

[0029] Preferred, such as Figure 4 As shown, mounting plates 17 are fixedly connected to the front sides of the two adjacent sliding plates 13. Push-pull handles 18 are fixedly connected to the middle of the front ends of the two mounting plates 17. Threaded plates 19 are fixedly connected to the front sides of the two adjacent sliding plates 17. Tightening screws 20 are threaded inside the two threaded plates 19 and pass through the two threaded plates 19 on both sides. Mounting grooves 21 are opened at the rear ends of the two mounting plates 17. Cleaning plates 22 are slidably connected inside the two mounting grooves 21, and cleaning cloths are wrapped around the outside of the cleaning plates 22.

[0030] In use, if the height of the display screen body 8 needs to be adjusted, first start the servo motor 5, which will drive the screw 4 to rotate. Since the connecting plate 7 is threadedly connected to the screw 4 and slidably connected to the guide rod 6, the connecting plate 7 moves up and down along the guide rod 6 when the screw 4 rotates, thereby raising and lowering the display screen body 8 to a suitable height. After adjustment, turn off the servo motor 5. If the display screen body 8 needs to be cleaned, first hold the two push-pull handles 18, and then push the two push-pull handles 18 at the same time, which will push the two mounting plates 17 and drive the two sliding plates 13 to move. At this time, the two sliding plates 13 move in the two sliding grooves 10 of the two clamping plates 9 through the two sliding blocks 11 respectively. At the same time, the cleaning cloth at the rear end of the cleaning plate 22 is in contact with the surface of the display screen body 8. During the wiping process, two compression springs 16 exert elastic pressure on two sliding plates 13 through two rotating shafts 12, ensuring that the cleaning cloth maintains appropriate contact force with the display screen surface, thus ensuring the cleaning effect and avoiding damage to the screen. After cleaning, push the cleaning assembly above the display screen body 8, pull the two push-pull handles 18, and then flip it upwards to move the cleaning plate 22 to the top of the display screen body 8. If the cleaning cloth needs to be replaced, unscrew the tightening screws 20, separate the two mounting plates 17, remove the cleaning plate 22 from the two mounting slots 21, replace the cleaning cloth, slide the cleaning plate 22 back into the two mounting slots 21, align the two mounting plates 17, and tighten the screws 20 to complete the replacement of the cleaning cloth.
