[0043] The embodiment of the present application discloses a flip-up curtain door, which is used to be installed on the compartment of a fire truck. Specifically, the flip-up curtain door includes a door body assembly 20, a curtain door assembly 30 and an outer door frame assembly 10; the outer door frame assembly 10 is used to be installed in the compartment; the door body assembly 20 is installed in the outer door frame assembly 10, and the top of the door body assembly 20 is hinged to the top of the outer door frame assembly 10 so as to be able to be flipped open or closed relative to the outer door frame assembly 10; the curtain door assembly 30 is arranged on the upper part of the door body assembly 20, so as to enable the door body to be opened or closed.

[0044] In this way, by arranging the curtain door assembly 30 on the door body assembly 20, the door body can be opened or closed by sliding the free end of the curtain door assembly 30 up and down relative to the door body. In this way, when performing fire rescue, it is only necessary to lift up the curtain door assembly 30 to open the door body assembly 20 to take out the fire-fighting equipment in the car, which is convenient and quick. In addition, since the door body assembly 20 is hinged to the outer door frame assembly 10 and can be opened or closed, the door body assembly 20 can be opened during maintenance to reveal a larger space for convenient maintenance.

[0045] The outer door frame assembly 10 includes an upper profile 11 and a left profile 12 and a right profile 13 arranged in parallel. The upper profile 11 is fixedly connected to the tops of the left profile 12 and the right profile 13. The top of the door body assembly 20 is hinged to the upper profile 11. The left profile 12, the right profile 13 and the upper profile 11 are all formed with a recessed structure 14. When the door body assembly 20 is closed relative to the outer door frame assembly 10, the edge of the door body assembly 20 is embedded in the recessed structure 14, so that the surface of the door body assembly facing away from the car is basically flush with the surface of the outer door frame assembly 10 facing away from the car, thereby ensuring the overall appearance of the car as much as possible. In addition, a shock-absorbing strip 15 is installed in the recessed structure 14, so that the impact force between the edge of the door body assembly 20 and the outer door frame assembly 10 can be reduced, thereby achieving a shock-absorbing effect.

[0046] The door body assembly 20 includes a frame 21, a curtain door installation assembly 22 installed on the upper part of the frame 21, and a locking assembly installed on the side of the frame 21;

[0047] The top of the frame 21 is hinged to the outer door frame assembly 10, that is, the upper door frame 211 of the frame 21 is hinged to the upper profile 11, the curtain door mounting assembly 22 is installed on the upper door frame 211, and the curtain door assembly 30 is installed on the curtain door mounting assembly 22. The locking assembly is used to lock the curtain door assembly 30 when the curtain door assembly 30 closes the frame 21 to ensure that the free end of the curtain door assembly 30 always contacts the lower door frame 212 of the frame 21 to prevent the curtain door assembly 30 from being bumped and moved upward during non-fire rescue operations, causing the lower part of the door frame to open.

[0048] In addition, a guide groove 24 is formed on the inner side of the frame 21. Specifically, a guide groove 24 is provided on the side opposite to the left door frame 213 and the right door frame 214 of the frame 21. The side of the curtain door assembly 30 is engaged with the guide groove 24 and can slide relative to the frame 21, thereby guiding the movement direction of the free end of the curtain door assembly 30 and ensuring that the free end of the curtain door assembly 30 can be aligned with the frame 21.

[0049] A curtain door rubber strip 25 is provided on the surface of the frame 21 away from the interior of the vehicle. The curtain door rubber strip 25 is used to be squeezed with the edge of the curtain door assembly 30 when the curtain door assembly 30 closes the frame 21, thereby sealing the gap between the two and preventing external pollutants such as dust and water from entering the interior of the vehicle through the gap.

[0050] The curtain door assembly 30 includes a rolling shutter shaft 31, a guide wheel 32 and a rolling shutter door 33. The rolling shutter shaft 31 and the guide wheel 32 can be rotatably arranged on the upper part of the door body assembly 20, specifically, installed on the curtain door mounting assembly 22. The rolling shutter shaft 31 can rotate relative to the curtain door mounting assembly 22. The rolling shutter door 33 is wound around the rolling shutter shaft 31, and the free end of the rolling shutter door 33 bypasses the guide wheel 32 and slides with the door body assembly 20, that is, the side of the rolling shutter door 33 slides with the guide groove 24 on the inner side of the frame 21, so that the free end of the rolling shutter door 33 can move up and down to open or close the door body assembly 20.

[0051] In detail, the locking assembly includes a first limiting barb 23 installed on the inner side of the frame 21, and the free end of the rolling door 33 of the curtain door assembly 30 is provided with a second limiting barb 34 through an elastic member 35. The elastic member 35 is used to make the second limiting barb 34 extend from the side of the curtain door assembly 30 so that the first limiting barb 23 and the second limiting barb 34 are engaged, thereby achieving locking of the rolling door 33.

[0052] The curtain door assembly 30 is provided with a release rod 36, which is used to pull the second limit hook 34 back from the side of the curtain door assembly 30 to disengage the first limit hook 23 and the second limit hook 34. In this way, personnel only need to pull the release rod 36 inward and lift the rolling door 33 upward to open the door frame. The unlocking is quick, meeting the rapid response requirements of fire rescue.

[0053] The flip-up curtain door also includes a gas spring assembly 40, one end of which is used to fix the carriage, and the other end of the gas spring assembly 40 is hinged to the door body assembly 20, so that when the door body assembly 20 is flipped open, the gas spring assembly 40 extends to support the door body assembly 20, and personnel do not need to hold the door body assembly 20 with one hand, which is more convenient. When the door body assembly 20 needs to be closed, it is only necessary to reset the gas spring assembly 40.

[0054] The flip-up curtain door also includes a lock assembly 50 for being set on the car body, and the lock assembly 50 is used to connect or separate from the bottom of the door body assembly 20, that is, when the lock assembly 50 body is connected to the lower door frame 212 of the door body assembly 20, the door body assembly 20 is locked, thereby keeping the door body assembly 20 closed to the outer door frame assembly 10. When the door body assembly 20 needs to be opened, it is only necessary to unlock the lock assembly 50 so that the lock assembly 50 is separated from the lower door frame 212.

[0055] The embodiment of the present application also discloses a fire truck, which includes a compartment and the above-mentioned flip-up curtain door arranged in the compartment.

[0056] In summary, the embodiment of the present application discloses a flip-up curtain door and a fire truck, in which a curtain door assembly 30 is arranged on a door body assembly 20, and the door body can be opened or closed by sliding the free end of the curtain door assembly 30 up and down relative to the door body. In this way, when performing firefighting and rescue, one only needs to lift up the curtain door assembly 30 to open the door body assembly 20 to take out the fire-fighting equipment in the car, which is convenient and quick. Moreover, since the door body assembly 20 is hinged to the outer door frame assembly 10 and can be flipped open or closed, the door body assembly 20 can be flipped open during maintenance to reveal a larger space for convenient maintenance.
