[0031] Currently, for the painting production of rail transit vehicles, a spray-bake paint booth equipped with an automatic spraying system is generally used for production operations. In the related art, the spray-bake paint booth of the automatic spraying system for rail transit vehicles is provided with an electric sliding door. The electric sliding door divides the spray-bake paint booth into two working areas and a robot preparation area, and the robot preparation area is located between the two working areas. The electric sliding door is provided with a notch for avoiding the robot track so that the electric sliding door will not interfere with the robot track when it is opened. However, the notch deteriorates the isolation effect between the working area and the robot preparation area, and the spraying robot is easily affected by high temperature, thereby affecting the service life of the spraying robot.

[0032] In view of the above technical problems, the present utility model proposes an opening and closing structure for an air avoidance door of an automatic spray-bake paint booth for rail transit vehicles. The opening and closing structure of the air avoidance door is arranged at the notch of the electric sliding door. When the electric sliding door moves, the first driver works to drive the first combined plate to rotate around the rotating shaft to a position perpendicular to the installation door. Then the second driver works to drive the second combined plate to rotate to a position perpendicular to the first combined plate, and the first combined plate and the second combined plate present a 90° angle, and the air avoidance door can improve the sealing effect of the installation door.

[0033] When the first combined plate and the second combined plate are in the closed state, the two are in the same plane and the edges are butted, and the size of the air avoidance door formed by splicing is large. Furthermore, the avoidance notch of the installation door can be designed larger; when the first combined plate and the second combined plate are in the open state, the two are perpendicular to each other, and when the installation door moves or flips, the air avoidance door will not interfere with other adjacent components.

[0034] Refer to Figure 1 and Figure 2 as shown below, the opening and closing structure of the clearance door of an automatic spray painting and baking room for rail transit vehicles according to an embodiment of the present utility model will be described.

[0035] Refer to Figure 1 and Figure 2 as 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 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 in transmission connection with 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 realize the action of turning up. In other embodiments, the installation door can be configured as a door with other opening and closing forms, which will not be described in detail herein.

[0036] It can be understood that the clearance door 1 further includes a bearing plate 11 and a drive plate 13. The bearing plate 11 is arranged on the electric sliding door 20 and 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 drive 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 drive plate 13 sleeved on the rotating shaft 12 is tightened by a tightening bolt so that the drive 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 drive 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.

[0037] 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 first driver 3 is configured as a first cylinder 4. The first cylinder 4 is fixed on the electric sliding door 20 through a first base plate 6 and a second base plate 7. Specifically, the first base plate 6 is riveted to the electric sliding door 20, the second base plate 7 is riveted to the electric sliding door 20, the first base plate 6 and the second base plate 7 are arranged vertically, the first cylinder 4 is located between the first base plate 6 and the second base plate 7 and is vertically arranged, one end of the cylinder body of the first cylinder 4 is riveted to the first base plate 6 through a right-angle sheet metal part, and the other end of the cylinder body of the first cylinder 4 is riveted to the second base plate 7 through a right-angle sheet metal part to realize the fixation of the first cylinder 4.

[0038] The slide rail 9 is arranged on the second base plate 7 and is vertically disposed. The slider 8 is arranged on the slide rail 9. The flap force seat 10 is arranged on the slider 8 and extends in the horizontal direction. The extending end of the flap force seat 10 is away from the electric sliding door 20. One end of the connecting rod 5 is connected to the end of the flap force seat 10 extending horizontally, and the other end is connected to the connecting rod 5 base arranged on the first combined plate 14. The advantage of the flap force seat 10 extending horizontally is that the connecting rod 5 can be designed shorter to improve the torque transmission efficiency.

[0039] The working principle is as follows: The first cylinder 4 is inflated, and the cylinder push rod of the first cylinder 4 pushes the slider 8 to move downward on the slide rail 9. The flap force seat 10 follows the slider 8 to move. The connecting rod 5 under the action of the flap force seat 10 pushes the first combined plate 14 to rotate downward around the axis of the rotating shaft 12 until it is parallel to the electric sliding door 20. The second cylinder 18 deflates, and the cylinder push rod of the first cylinder 4 pushes the slider 8 to move upward on the slide rail 9. The flap force seat 10 follows the slider 8 to move. The connecting rod 5 under the action of the flap force seat 10 pushes the first combined plate 14 to rotate upward around the axis of the rotating shaft 12 until it is perpendicular to the electric sliding door 20.

[0040] It can be understood that a transmission member 19 is provided at the end of the rotating shaft 12, and the transmission member 19 is configured as a gear. The electric sliding door 20 can also be provided with a third driver, and the third driver is in transmission connection with the transmission member 19. Since the first combined plate 14 and the rotating shaft 12 are fixedly connected through the driving plate 13, the first combined plate 14 can be driven to rotate by the third driver or by the first driver 3. The third driver is configured as a servo motor, and the output shaft of the servo motor is in transmission connection with the gear.

[0041] 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 relative to each other in some other embodiments.

[0042] 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.

[0043] 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.

[0044] It can be understood that a seal 21 is provided at the edge of the first combined plate 14. The seal 21 is a brush 22, and the brush 22 can abut against the electric sliding door 20, as well as the ground and the track of the automatic spray painting and baking room of the rail transit vehicle when the first combined plate 14 is turned downwards to close, so as to improve the sealing effect of the working area and the robot preparation area.
