When the electric sliding door is closed, the clearance door is in a downward closed state to improve the sealing performance between the working area and the robot preparation area.

[0031] The following refers to Figure 1 and Figure 2 shown to describe a clearance door for an automatic spray-bake paint booth of a rail transit vehicle according to an embodiment of the present utility model.

[0032] Refer to Figure 1 and Figure 2As shown, the installation door is configured as an electric sliding door 20, and the clearance door 1 is arranged at the notch at the bottom of the electric sliding door 20. The clearance door 1 includes a rotating shaft 12, a first combined plate 14, and a flap power mechanism 2. The rotating shaft 12 is rotatably arranged on the electric sliding door 20 and is horizontally arranged transversely. The first combined plate 14 is connected to the rotating shaft 12, and the flap power mechanism 2 is arranged on the electric sliding door 20 and is drivingly connected to the first combined plate 14. The first combined plate 14 can rotate around the rotating shaft 12 under the drive of the flap power mechanism 2 to achieve the action of turning up. In some other embodiments, the installation door can be configured as a door with other opening and closing forms, which will not be elaborated here in detail.

[0033] It can be understood that the clearance door 1 further includes a bearing plate 11 and a driving plate 13. The bearing plate 11 is arranged on the electric sliding door 20 and is fixed by rivets. There are three bearing plates 11 and they are arranged horizontally and evenly. Bearings are provided on the bearing plate 11, and the rotating shaft 12 passes through the bearings. One end of the driving plate 13 is connected to the first combined plate 14, and the other end is sleeved on the rotating shaft 12. The end of the driving plate 13 sleeved on the rotating shaft 12 is tightened by a tightening bolt so that the driving plate 13 is relatively fixed to the rotating shaft 12. The bearing plate 11 can keep a certain distance between the rotating shaft 12 and the electric sliding door 20, and the bearings provided on the bearing plate 11 make the rotation of the rotating shaft 12 smoother. The driving plate 13 can increase the rotation radius of the first combined plate 14 and avoid interference between the first combined plate 14 and the electric sliding door 20 or other adjacent components during the rotation process.

[0034] It can be understood that the flap power mechanism 2 is provided with a first driver 3, a slide rail 9, a slider 8, a flap force seat 10, and a connecting rod 5.

The third driver is configured as a servo motor, and the output shaft of the servo motor is in transmission connection with the gear.

[0038] It should be noted that in addition to being fixedly connected through the driving plate 13 as described above, the rotating shaft 12 and the first combined plate 14 can also be rotatably connected to each other in some other embodiments.

[0039] Refer to Figure 1 and Figure 2 As shown, the clearance door 1 is further provided with a second combined plate 15 and a second driver 17. The second combined plate 15 is arranged on one side of the first combined plate 14 through a hinge. The second driver 17 is configured as a second cylinder 18. One end of the second cylinder 18 is fixed on the first combined plate 14 through a sheet metal part, and the cylinder push rod of the second cylinder 18 is fixed on the second combined plate 15 through a sheet metal part.

[0040] It can be understood that the second combined plate 15 can be folded under the drive of the second cylinder 18 and form a 90° angle with the first combined plate 14. The second combined plate 15 can make the notch size of the electric sliding door 20 designed larger, and when the electric sliding door 20 moves, the second combined plate 15 can be retracted upward to prevent interference with the spraying robot in the robot preparation area.
