[0001] This utility model relates to the field of special vehicle technology, specifically to an electric flip-up mechanism for a pull-out extended compartment. Background Technology

[0002] Pull-out extended cabins are cabin structures with high flexibility and space expansion capabilities. Due to their large internal space and stable and reliable structure, they are widely used in military, medical, and emergency response fields.

[0003] Currently, with pull-out extended cabins, since the side cabins are folded into the main cabin, the main cabin floor needs to have a gap. The gap is usually decorated with a brush or cover plate, which does not have a good sealing effect, resulting in air leakage and dust entering the gap. Utility Model Content

[0004] The purpose of this utility model is to provide an electric flip-up mechanism for pull-out extended cabins, in order to solve the problem mentioned in the background art that the gap in the main cabin floor of the existing pull-out extended cabins does not have a good sealing effect when the side cabins are closed, resulting in air leakage and dust entering at the gap.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric flip-up mechanism for a pull-out extended compartment, comprising a main compartment, a main compartment floor fixedly connected to the surface of the main compartment, side compartments movably connected to both sides of the main compartment, side compartment floors fixedly connected to the surface of the side compartments, a lifting floor movably connected to the surface of the main compartment, flip-up panels movably connected to both sides of the lifting floor, hinges movably connected to the surface of the flip-up panels, an electric push rod movably connected to the bottom of the lifting floor, a main support fixedly connected to the surface of the lifting floor, a connecting seat fixedly connected to the surface of the flip-up panels, and a telescopic rod movably connected inside the electric push rod.

[0006] Preferably, there are two sets of flaps, and the two sets of flaps are distributed at both ends of the lifting floor. The flaps are movably connected to the main cabin through the lifting floor, and the lifting floor is movably connected to the flaps through hinges.

[0007] Preferably, the lifting floor is movably connected to the main support and the electric push rod, the flip plate is movably connected to the electric push rod via the connecting seat, and the lifting floor is movably connected to the flip plate via the electric push rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses an electric push rod to drive the flap to rotate. The electric push rod and the main cabin extension can be linked for control to prevent the flap from not folding when the side cabin is closed. The lifting floor and the flap are connected by a hinge, which makes the flap more stable when rotating. The flap can be rotated by a telescopic rod, which saves time and effort when using it.

[0014] 2. This utility model provides a better fit when connecting the main cabin floor and the side cabin floor by setting a second connecting plate and a limiting plate at both ends of the flap. The flap can also be sealed by using a locking block and a protrusion to cooperate with the side cabin and the main cabin after opening, preventing dust from entering. Attached Figure Description

[0023] Furthermore, there are two sets of flaps 31, and the two sets of flaps 31 are distributed at both ends of the lifting floor 3. The flaps 31 are movably connected to the main cabin 1 through the lifting floor 3. The lifting floor 3 is movably connected to the flaps 31 through the hinges 32. The flaps 31 can rotate within a certain range along the hinges 32, and the connection between the flaps 31 and the lifting floor 3 is more stable through the hinges 32.

[0024] Furthermore, the lifting floor 3 is movably connected to the electric push rod 4 via the main support 41, and the flip plate 31 is movably connected to the electric push rod 4 via the connecting seat 42.

The electric push rod 4 can change different angles via the main support 41, making it more flexible when driving the connecting seat 42 to change the position of the flip plate 31.

[0025] Furthermore, the electric push rod 4 is movably connected to the connecting seat 42 via the telescopic rod 43, and the flap 31 is movably connected to the lifting floor 3 via the telescopic rod 43. The telescopic rod 43 extends and retracts inside the electric push rod 4. When the telescopic rod 43 extends outward, the flap 31 folds upward, thereby allowing the side compartment 2 to be stored.

[0026] Furthermore, the lifting floor 3 is provided with first connecting plates 5 at both ends, the flip plate 31 is movably connected to one side of the flip plate 31 and to the other side of the flip plate 31 with a limit plate 52, the main cabin floor 11 is movably connected to the surface of the main cabin floor 11 with a first fixing plate 53, the side cabin floor 21 is movably connected to the surface of the side cabin floor 21 with a second fixing plate 54, the surface of the first connecting plate 5 is provided with a sealing strip 6, the surface of the first fixing plate 53 is movably connected to a locking block 61, and the surface of the second fixing plate 54 is movably connected to a protrusion 62. The locking block 61 and the protrusion 62 are made of rubber. When the flip plate 31 is folded to make the limit plate 52 and the locking block 61 abut, the connection between the flip plate 31 and the main cabin floor 11 is ensured to be tight, and the cabin is sealed by the locking block 61 and the sealing strip 6.

[0027] Furthermore, the first connecting plate 5 is engaged with the second connecting plate 51 via the sealing strip 6, the first fixing plate 53 is movably connected to the limiting plate 52 via the locking block 61, the hinge 32 is provided on the first connecting plate 5 and the second connecting plate 51, and the first connecting plate 5 is connected to the sealing strip 6 below the flip plate 31, so that the connection between the first connecting plate 5 and the second connecting plate 51 is more snug and wear is reduced.

[0028] Furthermore, the second fixed plate 54 is movably connected to the limiting plate 52 via the protrusion 62, and the side cabin floor 21 is movably connected to the limiting plate 52 via the protrusion 62. When connecting the limiting plate 52 and the second fixed plate 54, the protrusion 62 acts as a buffer, and the connection between the lifting floor 3 and the side cabin floor 21 is sealed through the protrusion 62.

[0029] Working principle: When using the extended cabin, the cabin body is first unfolded, the side cabin 2 expands outward, the flap 31 is opened by the electric push rod 4, the flap 31 rotates along the hinge 32 until it is parallel to the lifting floor 3, the flap 31 is connected to the main cabin floor 11 by the locking block 61 to ensure a seal, the flap 31 is sealed at the connection with the side cabin floor 21 by the protrusion 62. When the cabin body is retracted, the electric push rod 4 and the main cabin 1 can be linked for control. Only when the electric push rod 4 pushes the flap 31 to fold can the side cabin 2 be retracted.
