Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and 2, fig. 5 and 6, a floor lifting structure is shown, which includes a floor 1 and a substrate 2 located below the floor 1, that is, the floor 1 and the substrate 2 are located in a position relationship of being arranged up and down, a lifting mechanism capable of lifting or lowering the floor 1 is installed on the substrate 2, the lifting mechanism includes a driving member 3 installed on the substrate 2, a transmission mechanism connected to the driving member 3, and a crank mechanism connected to the transmission mechanism, the crank mechanism is fixed at the bottom of the floor 1, the driving member 3 drives the transmission mechanism to rotate, the transmission mechanism drives the crank mechanism to move, and finally the movement of the crank mechanism drives the floor 1 to lift.

Specifically, the transmission mechanism comprises a main transmission rod 4 arranged along the length direction of the substrate 2 and a plurality of driven connecting rods 5 connected to the main transmission rod 4 at intervals along the length direction of the main transmission rod 4, the driven connecting rods 5 are connected with the crank mechanism, and the main transmission rod 4 is connected with the driving piece 3. The driving piece 3 drives the main transmission rod 4 to rotate, so that the driven connecting rod 5 is driven to rotate, the crank mechanism is driven to move, and finally the movement of the crank mechanism drives the floor 1 to lift. In this embodiment, the number of the plurality of driven connecting rods 5 is 3, and the driven connecting rods 5 are arranged in parallel at intervals, wherein two driven connecting rods 5 are respectively connected to two ends of the main transmission rod 4, another driven connecting rod 5 is connected to the middle of the main transmission rod 4, and each driven connecting rod 5 is arranged perpendicular to the main transmission rod 4. Through setting up like this for drive mechanism evenly distributed can be more stable when upwards jacking floor 1 on base plate 2. It is equivalent to that a net-shaped transmission mechanism is distributed at the bottom of the floor 1, so that the floor 1 can be stably lifted or lowered after the cooperative linkage of the transmission mechanism.

A crank mechanism is arranged at both ends of each driven connecting rod 5, as shown in fig. 3 and 4, and fig. 7 and 8, the crank mechanism comprises a base 6.1 fixed on the base plate 2, a first connecting rod 6.2 hinged with the upper end of the base 6.1, a second connecting rod 6.3 hinged with the first connecting rod 6.2, and a fixing block 6.4 hinged with the second connecting rod 6.3, the fixing block 6.4 is fixedly arranged at the bottom of the floor 1, and the first connecting rod 6.2 is hinged with the driven connecting rod 5. When the main transmission rod 4 transmits power to the driven connecting rod 5, the driven connecting rod 5 drives the first connecting rod 6.2 and the second connecting rod 6.3 to jack in the vertical direction, so that the floor 1 is lifted.

The limiting groove 6.5 is formed in the first connecting rod 6.2, the limiting block 6.6 matched with the limiting groove 6.5 is arranged on the base 6.1, and when the first connecting rod 6.2 and the second connecting rod 6.3 are located at vertical positions, the floor 1 is prevented from descending through locking of the limiting block 6.6.

Specifically, during transmission work, the main transmission rod 4 is connected with the driven connecting rod 5 through a connecting piece, the connecting piece comprises a fixed seat 7.1 fixed on the base plate 2 and a connecting rod 7.2 hinged to the top of the fixed seat 7.1, one end of the connecting rod 7.2 is fixedly connected with the main transmission rod 4, and the other end of the connecting rod 7.2 is hinged to the driven connecting rod 5, as shown in fig. 6. When driving piece 3 drive final drive pole 4 rotated, because final drive pole 4 and connecting rod 7.2 one end fixed connection to drive connecting rod 7.2 and rotate, the other end and the driven connecting rod 5 of connecting rod 7.2 are articulated, and then drive driven connecting rod 5 and move along its length direction, finally make first connecting rod 6.2, second connecting rod 6.3 change to vertical direction, be about to floor 1 jacking.

In this embodiment, the driving member 3 is a worm gear motor, and an output shaft of the worm gear motor is connected to the main transmission rod 4. When the motor rotates reversely, the lifted floor 1 can be lowered to restore the original position.

In addition, in order to make the lifting of the floor 1 more stable, a guide rail 8.1 is vertically arranged on the side of the base plate 2, and a slide block 8.2 matched with the guide rail 8.1 is arranged on the side of the floor 1, as shown in fig. 5. In this embodiment, because the base plate 2 is rectangular, the guide rails 8.1 in the vertical direction are arranged at four corners of the rectangular base plate 2, and the floor 1 slides in the guide rails 8.1 through the sliding blocks, so that the floor 1 is more stably lifted.

The floor lifting structure is applied to a caravan, the caravan comprises a frame, and the floor 1 lifting structure is installed on the frame. After the carriage is expanded towards two sides, a step difference exists between the floor 1 and the expanded carriage, and at the moment, the floor 1 is jacked up through a floor 1 lifting structure, so that the step difference is eliminated; when the expanded car needs to be retracted, the floor 1 is lowered through the floor 1 lifting structure, and then the expanded car is retracted, as shown in fig. 9 to 11.
