[0002] The existing RV roof lifting device can only raise the roof alone when in use. The hammock is often fixed on the original roof structure. The raising of the roof and the lowering of the hammock are operated separately. Moreover, when there is a hammock, the roof raising function does not effectively expand the space inside the vehicle, which is a great regret for the space utilization of the RV.

The bottom of the electric lifting push rod 4 is hoisted on the RV roof 1, and the lifting rod extends upward to connect a corner of the lifting roof 2. One end of the sling 6 is fixed to the RV roof, and the sling 6 passes through the fixed pulley A5 fixed on the RV roof 1, and the sling 6 is extended downward by the top rod 7 fixed on the lifting roof 2 and the movable pulley 701 located at the lower end of the top rod 7. After the sling 6 passes through the movable pulley 701, it passes upward around the fixed pulley B9 located on the RV roof 1. The fixed pulley A5 and the fixed pulley B9 are fixed on the RV roof 1 through the bracket 8. After the sling 6 passes through the fixed pulley B9, it is fixedly connected to the anchor point 10 on the hammock 3.
[0005] As a preferred embodiment of the present invention, a retractable sealing shed 11 is provided at the edge of the lifting roof 2, and when the sealing shed 11 is opened, it can keep warm, prevent rain, wind and light.
[0006] As a preferred embodiment of the present invention, the upper end of a locking chain 12 is fixed to the lifting top 2, and the lower end of the locking chain 12 is connected to the hammock 3 with a movable latch structure, so as to achieve the purpose of driving the hammock 3 to rise and fall synchronously with the lifting top 2.
[0007] As a preferred embodiment of this solution, the lifting top 2 rises upward under the lifting action of the electric lifting push rod 4, and the top rod 7 connected to the lifting top 2 rises accordingly. When the lower end of the locking chain 12 is detached from the hammock 3, the sling 6 will be tightened toward the end anchor point 10 under the action of the gravity of the hammock 3. At the same time, the anchor point 10 together with the hammock 3 is lowered under the action of gravity, realizing an upward extending action of the electric lifting push rod 4, and at the same time controlling the two actions of the lifting top 2 rising and the hammock 3 falling, thereby realizing the linkage lifting function of the top bed.
[0008] As a preferred embodiment of this solution, when the lifting top 2 can be lowered downward under the contraction of the electric lifting push rod 4, the top rod 7 connected to the lifting top 2 will follow and fall, and the movable pulley 701 at the lower end of the top rod 7 will extend the sling 6 downward, and the sling 6 will be tightened in the opposite direction to the end anchor point 10 under the action of the top rod 7. At the same time, the anchor point 10 and the hammock 3 will rise upward under the tightening force of the sling 6, realizing a downward movement of the electric lifting push rod 4, and at the same time controlling the two movements of the lifting top 2 descending and the hammock 3 rising, so as to realize the linkage lowering and raising function of the top bed.
[0009] As a preferred embodiment of the present invention, when the lifting roof 2 is lifted by the electric lifting push rod 4, the locking chain 12 fixed on the lifting roof 2 will rise with the movement. When the lower end of the locking chain 12 is fixedly connected to the hammock 3 in the form of an electric latch or a manual latch, the hammock 3 will rise together with the lifting roof 2, thereby expanding the living space inside the RV.
