[0030] At present, for the painting production of rail transit vehicles, a spray-drying paint room equipped with an automatic spraying system is generally used for production operations. The Chinese patent publication number CN117983465A discloses an automatic spraying system for rail transit vehicles. The spray-drying paint room is provided with an electric sliding door to separate the spray-drying paint room into a working area and a robot preparation area. The electric sliding door is provided with a gap to avoid the robot track so that the electric sliding door will not interfere with the robot track when opened, but the gap makes the isolation effect between the working area and the robot preparation area worse, and the spraying robot is easily affected by high temperature, thereby affecting the service life of the spraying robot.

[0031] In response to the above technical problems, an embodiment of the utility model proposes an opening and closing structure of a flip door for an automatic spray-drying paint room of a rail transit vehicle. The flip door is driven to rotate by a connecting rod driving mechanism, and the opening method is more energy-saving and efficient than an electric sliding door.

[0032] Refer to the following Figures 1 to 4 The figure shows an opening and closing structure of a flip door for an automatic spray-drying paint room for rail transit vehicles according to an embodiment of the utility model.

[0033] Reference Figure 1 As shown, the flip door includes a flip door body 1, a connecting rod driving mechanism 10, a second driver 16 and a track door. The flip door body 1 is arranged on a column 27 of the side wall of the automatic spraying and baking paint room through a hinge, and can rotate around the column 27. The connecting rod driving mechanism 10 is arranged on the column 27 and is transmission-connected with the flip door body 1. The flip door body 1 is driven by the connecting rod driving mechanism 10 to realize automatic opening and closing. The second driver 16 is arranged at the bottom of the flip door body 1, and the track door is arranged at the bottom of the flip door body 1. The second driver 16 is transmission-connected with the track door to drive the track door to move up and down in the vertical direction.

[0034] Reference Figure 2As shown in the figure, the track door is provided with a second guide rail 13 and a second guide block 14. The second guide rail 13 is located on both sides of the track door body 4, and the second guide block 14 is arranged on the flip door body 1 and is slidably connected to the second guide rail 13. The second guide rail 13 is arranged in the vertical direction, and two second guide blocks 14 are arranged on each second guide rail 13. The second driver 16 is configured as a second cylinder 17. The cylinder block of the second cylinder 17 is arranged on the flip door body 1, and the cylinder push rod of the second cylinder 17 is connected to the track door body 4. A force seat 28 for connecting the cylinder push rod of the second cylinder 17 is provided on the track door body 4.

[0035] The working principle of the track door is as follows: When the second cylinder 17 is inflated, the cylinder push rod of the second cylinder 17 pushes the force seat 28, thereby driving the track door body 4 to move downward. The second guide rail 13 and the second guide block 14 play a guiding role, making the movement of the track door body 4 more stable dynamically; when the second cylinder 17 deflates, the cylinder push rod of the second cylinder 17 pulls the force seat 28, thereby driving the track door body 4 to move upward. The track door body 4 moves more stably under the guiding action of the second guide rail 13 and the second guide block 14. The setting of the force seat 28 can increase the stress area of the track door body 4 and improve the transmission efficiency of the thrust of the second cylinder 17.

[0036] It can be understood that a seal 7 is also provided on the track door body 4. The seal 7 is located at the bottom edge of the track door body 4. The seal 7 can abut against the ground or the robot track provided in the automatic spray baking paint room to improve the sealing performance of the flip door. The seal 7 is configured as a fireproof rubber block 8, and the fireproof rubber block 8 has a relatively thick thickness and good heat insulation effect. In some other embodiments, the seal 7 can also be provided on the side of the track door body 4 to improve the sealing performance between the track door body 4 and the flip door body 1.

[0037] In addition, the track door body 4 is also provided with a frame 9, and the frame 9 protrudes towards the flip door body 1. The frame 9 divides the track door body 4 into multiple spaces. For example, the second guide rail 13 and the second guide block 14 are located in independent spaces, and the second driver 16 is located in an independent space. The advantage of such a design is that it improves the sealing effect of the track door body 4, and the components of the track door are not easily affected by high temperature.

[0038] Refer to Figure 3 and Figure 4 As shown in the figure, in the connection drive mechanism, the fixed seat 11 is fixed to the column 27 on the side wall of the automatic spray baking paint room by screws or rivets. The fixed seat 11 is provided with two parallel mounting seats 12. The mounting seat 12 is provided with a first guide rail 5. The moving seat 15 is provided with a first guide block 6, and the first guide block 6 is slidably connected to the first guide rail 5, so that the moving seat 15 can move along the length direction of the first guide rail 5.

[0039] The first driver 2 is configured as the first cylinder 3. The cylinder block of the first cylinder 3 is arranged on the moving seat 15, and the cylinder push rod of the first cylinder 3 is connected to the fixed seat 11. One end of the connecting rod 24 is rotatably arranged on the moving seat 15 through a pin, and the other end is rotatably connected to the sliding seat 22 through a pin. The rocker 18 is divided into two parts. One part is a cylindrical structure 19, and the other part is an arc-shaped structure 20. The cylindrical structure 19 is connected to the arc-shaped structure 20. The end of the cylindrical structure 19 is rotatably arranged on the fixed seat 11 through a pin. The sliding seat 22 is provided with a chute, and the cylindrical structure 19 is clamped in the chute. The sliding seat 22 can move along the length direction of the cylindrical structure 19 of the rocker 18. The arc-shaped structure 20 is provided with an arc-shaped channel 21. The connecting seat 23 is arranged on the arc-shaped structure 20 through a pin, and the pin passes through the arc-shaped channel 21. The connecting seat 23 can slide along the arc-shaped channel 21. The arc-shaped structure 20 of the rocker 18 is to prevent the front part of the rocker 18 from colliding with the connecting seat 23 when moving. The arc-shaped channel 21 of the rocker 18 can enable the rocker 18 to displace along a fixed trajectory, and can also allow the rocker 18 to have a greater degree of freedom, release the excess power generated by the cylinder through its own displacement movement, avoid mechanism damage, and enable the entire rocker 18 to achieve a large-amplitude flipping action.

[0040] The first rocker arm 25 is used to connect the fixed seat 11 and the rocker 18. One end of the first rocker arm 25 is rotatably arranged on the fixed seat 11, and the other end is rotatably arranged on the rocker 18. The first rocker arm 25 is connected to the fixed seat 11 and the rocker 18 through pins. The second rocker arm 26 is used to connect the fixed seat 11 and the sliding seat 22. One end of the second rocker arm 26 is rotatably arranged on the fixed seat 11, and the other end is rotatably arranged on the sliding seat 22. The first rocker arm 25 is connected to the fixed seat 11 and the sliding seat 22 through pins. It should be noted that the second rocker arm 26 and the connecting rod 24 use the same pin. The function of the first rocker arm 25 is to further release the excess power generated by the cylinder and avoid mechanism damage. The function of the second rocker arm 26 is to stabilize the movement of the slider and the movement of the connecting rod 24.

[0041] The working principle of the connection driving mechanism is as follows: When the first cylinder 3 is inflated, the cylinder body of the first cylinder 3 will be pushed to the side away from the fixed seat 11, and at the same time, it will drive the moving seat 15 to move outward along the first guide rail 5. The moving seat 15 pulls the connecting rod 24 outward, and the connecting rod 24 then pulls the second rocker arm 26 to move downward. The second rocker arm 26 drives the sliding seat 22 to push the rocker 18 to turn outward. While the rocker 18 is turning, the first rocker arm 25 will rotate; during the process of the rocker 18 turning outward, the sliding seat 22 will also move downward along the cylindrical structure 19 of the rocker 18 to achieve a large-amplitude turning action of the rocker 18. When the rocker 18 turns outward, it will drive the arc-shaped structure 20 at its front end to pull the bolt, and drive the flip door to open outward through the connecting seat 23. A certain displacement is generated between the arc-shaped channel 21 inside the arc-shaped structure 20 and the bolt of the fixed connecting seat 23, further realizing the large-amplitude turning action of the rocker 18, and finally completing the full opening of the flip door.

[0042] When the first cylinder 3 deflates, the cylinder body of the first cylinder 3 will be pulled to the side close to the fixed seat 11, and at the same time, it will drive the moving seat 15 to move inward along the first guide rail 5. The moving seat 15 pulls the connecting rod 24 inward, and the connecting rod 24 then pulls the second rocker arm 26 to move upward. The second rocker arm 26 drives the sliding seat 22 to push the rocker 18 to turn inward. While the rocker 18 is turning, the first rocker arm 25 will rotate; during the process of the rocker 18 turning inward, the sliding seat 22 will also move upward along the cylindrical structure 19 of the rocker 18 to achieve a large-amplitude turning action of the rocker 18. When the rocker 18 turns inward, it will drive the arc-shaped structure 20 at its front end to push the bolt, and drive the flip door to close inward through the connecting seat 23. A certain displacement is generated between the arc-shaped channel 21 inside the arc-shaped structure 20 and the bolt of the fixed connecting seat 23, further realizing the large-amplitude turning action of the rocker 18, and finally completing the full closing of the flip door.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
