Description

Technical Field

[0001] This utility model relates to the field of vehicle equipment, and in particular to a plug door duct shielding device. Background Technology

[0002] Due to its significant advantages, sliding doors have been widely used in public transportation such as subways, buses, and trains. With the rapid development of train electrification and intelligence, sliding door systems have also become the preferred application for the entry and exit opening and closing systems of smart buses.

[0003] In order for electric sliding doors to open and close properly, the top door support frame needs to be able to slide back and forth normally within the door's opening range. Currently, one way to place the door support frame is in the air duct between the interior and exterior roofs of the vehicle. However, the air duct will be exposed after the door is opened, which will affect the overall sealing, aesthetics, and technological feel of the vehicle. Utility Model Content

[0004] The purpose of this utility model is to provide a duct shielding device for a sliding door, which has the advantage of shielding and protecting the duct during the opening and closing of the sliding door, thereby improving the sealing performance and aesthetics.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sliding door duct blocking device, including a duct plate, a slide rail at the front end of the duct plate, a door carrier movably arranged inside the slide rail, a limiting mechanism on one side of the door carrier, the limiting mechanism including a fixing block one, a fixing pin one, a fixing block two, a return spring and a fixing pin two, a winding device at the inner end of the limiting mechanism, a blocking cloth sleeved on the outer end of the winding device, the blocking cloth being connected to the door carrier, a fixing block one fixedly installed on one side of the door carrier, a fixing pin one fixedly installed at the lower end of the fixing block one, a fixing block two fixedly installed below the winding device, a return spring fixedly installed at the upper end of the fixing block two, and a fixing pin two fixedly installed at the upper end of the return spring.

[0006] Preferably, the winding device is provided with positioning holes at both the upper and lower ends. The diameter of the positioning holes is matched with that of the fixing pin one and the fixing pin two. The positioning holes facilitate the fixing of the winding device by locking the positioning holes with the fixing pin one and the fixing pin two.

[0007] Preferably, a mounting block is fixedly installed at one end of the gantry near the rewinder, and a fixing shaft is fixedly installed inside the mounting block.

[0008] Preferably, the outer end of the fixed shaft is rotatably connected to a rotating sleeve, and the outer end of the rotating sleeve is fixedly installed with a locking block. The locking block facilitates the rotation of the rotating sleeve to drive the locking block to fix the covering cloth.

[0009] Preferably, the end of the card block away from the fixed axis is evenly provided with a number of teeth, and the end of the card block near the fixed axis is fixedly installed with a pressing plate. By setting the teeth, when the card block fixes the cover cloth, the teeth will insert into the interior of the cover cloth, thereby improving the stability of the fixation. The pressing plate makes it easy for the user to move the card block by pressing the pressing plate.

[0010] In summary, this utility model has the following beneficial effects:

[0011] 1. The air duct shielding device for the train's sliding door works as follows: When the sliding door is open, the carrying frame slides to pull the shielding cloth to block the air duct. When the sliding door is closed, the carrying frame slides back to its original position, allowing the shielding cloth to be wound up and retracted by the winder. When installing the winder, the return spring is pressed to retract it. Then, the positioning hole on the winder is aligned with the fixing pin and inserted. After releasing the return spring, it resets and drives the fixing pin to press against the positioning hole at the lower end of the winder, thus fixing the winder vertically. When the winder is damaged and needs to be replaced, simply press the return spring downwards to disengage the fixing pin from the positioning hole. Finally, the winder can be removed for replacement. This improves the efficiency of winder installation and removal and enhances the practicality of the train's sliding door air duct shielding device.

[0012] 2. When connecting the shielding cloth to the gantry frame of this train's sliding door ventilation duct shielding device, first pull a section of the shielding cloth out from the retractor, then insert one end of the shielding cloth into the mounting block, and then press the pressing plate to make the pressing plate drive the rotating sleeve to rotate, thereby causing the locking block to press against the shielding cloth for limiting. When the locking block fixes the shielding cloth, the locking teeth will insert into the interior of the shielding cloth, thereby improving the stability of the fixation and facilitating the quick connection of the shielding cloth to the gantry frame, thus improving the convenience of the train's sliding door ventilation duct shielding device.

A fixing block 6 is fixedly installed on one side of the gantry 3. A fixing pin 7 is fixedly installed at the lower end of the fixing block 6. A fixing block 8 is fixedly installed below the winder 4. A return spring 9 is fixedly installed at the upper end of the fixing block 8. A fixing pin 10 is fixedly installed at the upper end of the return spring 9. By pressing the return spring 9, the return spring 9 is retracted. Then, the winder 4 is aligned with the fixing pin 7. After releasing the return spring 9, the return spring 9 returns to its original position and drives the fixing pin 10 to press against the lower end of the winder 4, thereby fixing the winder 4. The setting of the limiting mechanism facilitates the assembly and disassembly of the winder 4.

[0020] In this embodiment, positioning holes 11 are provided at both the upper and lower ends of the winding device 4. The diameter of the positioning holes 11 is matched with that of the fixing pin 1 7 and the fixing pin 2 10. The positioning holes 11 facilitate the fixing of the winding device 4 by locking the positioning holes 11 with the fixing pin 1 7 and the fixing pin 2 10.

[0021] In this embodiment, a mounting block 12 is fixedly installed at one end of the gantry 3 near the rewinder 4, and a fixing shaft 13 is fixedly installed inside the mounting block 12.

[0022] In this embodiment, a rotating sleeve 14 is rotatably connected to the outer end of the fixed shaft 13, and a locking block 15 is fixedly installed on the outer end of the rotating sleeve 14.

With the setting of the teeth 16, when the locking block 15 fixes the cover cloth 5, the teeth 16 will insert into the interior of the cover cloth 5, thereby improving the stability of the fixation. The pressing plate 17 makes it easy for the user to move the locking block 15 by pressing the pressing plate 17.

[0024] In this embodiment, a sliding door duct shielding device is installed by pressing the return spring 9 to retract the winder 4, then aligning the positioning hole 11 on the winder 4 with the fixing pin 7 and inserting it. After releasing the return spring 9, it resets and drives the fixing pin 10 to press against the positioning hole 11 at the lower end of the winder 4, thus fixing the winder 4 vertically. When connecting the shielding cloth 5 to the door frame 3, the shielding cloth 5 is first pulled out a section from the winder 4, then one end of the shielding cloth 5 is inserted into the mounting block 12. Then, the pressing plate 17 is pressed, causing the pressing plate 17 to rotate the rotating sleeve 14, thereby causing the locking block 15 to press against the shielding cloth 5 for limiting its position. When the locking block 15 fixes the shielding cloth 5, the locking teeth 16 insert into the interior of the shielding cloth 5, thereby improving the stability of the fixation and facilitating quick connection of the shielding cloth 5 to the door frame 3. When the sliding door is open, the door carrier 3 slides, pulling the shielding cloth 5 to block the air duct.
