One end of the fixing rod 305 is welded or bolted to the inner side of the lower car panel 3, and the other end is fixedly connected with a stopper for limiting the moving position of the fixing rod 305.

The side of the fixed rod 305 is connected with a rack 306 engaged with the gear 303, and is used for driving the lower carriage plate 3 to horizontally move through the rotation of the screw rod pipe 301.

When in use, the opening and closing process of the carriage body 1 comprises the following steps:

the method comprises the following steps: as shown in fig. 3-5, the two-shaft motor 4 is started and drives the two transmission shafts 105 to rotate, and the driving wheels 106 at the ends of the transmission shafts 105 are engaged with the driving wheels 203, so as to drive the rotating shafts 201 on the two side upper carriage plates 2 to rotate.

The rotating shaft 201 rotates, and the driven gear 205 and the driving gear 206 are meshed with each other, so that the rotating shaft 201 can synchronously drive the two screw rods 202 to rotate. The screw rod 202 rotates to enable the screw rod pipe 301 matched with the screw rod 202 to generate upward axial stress, and under the action of the gravity of the lower carriage plate 3 and the blocking effect of the upper carriage plate 2 on the lower carriage plate 3, the screw rod pipe 301 cannot axially move, so that the screw rod pipe 301 and the screw rod 202 synchronously rotate.

The screw pipe 301 rotates, so that the fixing rod 305 moves towards the outside of the car body 1 through the engagement of the gear 303 and the rack 306, so as to push the lower car plate 3 towards the outside of the car body 1, and when the stopper abuts against the end of the connecting rod 304, the fixing rod 305 is blocked and cannot move, and at this time, the lower car plate 3 is located at the outside of the upper car plate 2, as shown in fig. 9.

Step two: the rotating shaft 201 continues to rotate, and the fixing rod 305 is blocked and cannot move, so that the screw rod pipe 301 cannot continue to rotate, and the screw rod 202 continues to rotate under the driving of the rotating shaft 201, so that the screw rod pipe 301 axially moves upwards, and the screw rod pipe 301 drives the lower carriage plate 3 to move upwards through the fixing rod 305.

When the screw rod pipe 301 moves to the upper end of the screw rod 202 and cannot move, if the upper end surface of the screw rod pipe 301 is abutted against the lower surface of the bearing support connected with the screw rod 202, or a limiting block is welded on the side surface of the upper carriage plate 2, the position of the screw rod pipe 301 moving upwards is limited by the limiting block. So that rotation of the screw 202 does not drive the screw tube 301 to continue moving upward. The lower panel 3 is now stacked on the outside of the upper panel 2 so that the overall width of the side panel is reduced, as shown in fig. 10.

Step three: the pivot 201 continues to rotate, because the unable up-moving of continuation of lead screw pipe 301, thereby make the rotation of lead screw 202 obstructed, make lead screw 202 and lead screw pipe 301 lock each other, lead screw 202 is unable to rotate, lock each other between driven gear 205 and driving gear 206, thereby make and go up the railway carriage or compartment board 2 and realize the locking between pivot 201, when pivot 201 continues to rotate, then drive through lead screw 202 and go up railway carriage or compartment board 2 and realize the upset, then make the side railway carriage or compartment board upset of going up railway carriage or compartment board 2 and lower railway carriage or compartment board 3 constitution open, as shown in fig. 11.

Step four: when the side carriage plate needs to be closed, the double-shaft motor 4 is controlled to rotate reversely, so that the rotating shaft 201 rotates reversely, the upper carriage plate 2 and the lower carriage plate 3 rotate to vertical positions along with the rotating shaft 201 synchronously under the action of gravity, as shown in fig. 10, the rotating shaft 201 rotates continuously reversely, and the screw rod 202 is driven to rotate reversely, so that the screw rod pipe 301 moves vertically downwards.

When the lower carriage plate 3 moves to the lowest part, the lower surface of the lower carriage plate 3 abuts against the upper surface of the bottom plate 101, the axial movement of the screw rod pipe 301 is blocked, so that the screw rod 202 drives the screw rod pipe 301 to synchronously rotate, and the gear 303 and the rack 306 are utilized, so that the fixing rod 305 moves towards the inner side of the carriage body 1, the lower carriage plate 3 is pulled towards the inner side of the carriage body 1, when the lower carriage plate 3 abuts against the end part of the connecting rod 304, the moving position of the lower carriage plate 3 is limited, at the moment, the upper carriage plate 2 and the lower carriage plate 3 are closed, as shown in fig. 4, and the closing between the side carriage plate and the carriage body 1 is realized.

Further, sealing strips or dust-proof brush strips and the like are arranged on two sides of the upper compartment plate 2, and are used for sealing the space between the upper compartment plate 2 and the upright post 103 through the sealing strips or the dust-proof brush strips, and the fixing rod 305 is guaranteed to move between the upper compartment plate 2 and the upright post 103.

Meanwhile, the lower surface of the lower carriage plate 3 is provided with a plurality of bull-eye wheels, so that when the lower surface of the lower carriage plate 3 is abutted to the bottom plate 101, the horizontal movement can be realized through the bull-eye wheels, and the reliability and stability of the overall action are improved. And, there is the guard shield board lower carriage board 3 medial surface through the screw, and lead screw pipe 301 is located the guard shield board, through the guard shield board to the holistic protection of lead screw pipe 301, gear 303 and dead lever 305, avoids receiving the condition emergence of the goods influence in the carriage railway carriage or compartment body 1.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
