[0031] With the above scheme: when the moving rod 216 moves, the protruding block 217 moves synchronously, and when one set of clamping grooves 215 is clamped with the clamping block 214, the protruding block 217 is clamped with the recess A 210, at this time, the rotation of the rotating shaft 212 and the moving rod 216 can drive the rotating block 209 to rotate, and since the protruding block 217 is not in contact with the recess B 211 at this time, the threaded rod 204 will not be driven to rotate; the outer wall of the rotating block 209 is provided with two sets of traction ropes 208, and the two sets of traction ropes 208 are fixed on the outer wall of the rotating wheels 207 on both sides, and the two sets of traction ropes 208 are staggered on the outer wall of the rotating block 209, one set of traction ropes 208 is wound from above the rotating block 209 to the rotating wheel 207, and the other set of traction ropes 208 is wound from below the rotating block 209 to the other rotating wheel 207, when the moving rod 216 drives the rotating block 209 to rotate, it will pull the rotating wheels 207 on both sides to rotate at the same time through the traction ropes 208, and the two sets of rotating wheels 207 can rotate towards each other or in opposite directions, since the two sets of rotating wheels 207 are fixed with the two sets of corresponding side plates 202, the two sets of side plates 202 can be driven to flip up or down at the same time.

[0032] As shown in Figures 2 to 5 When the moving rod 216 moves to the other set of clamping grooves 215 and is clamped with the clamping block 214, the protruding block 217 is clamped with the recess B 211, so that the threaded rod 204 can be driven to rotate, and since the outer wall of the moving rod 216 is not in contact with the inner wall of the rotating block 209, and the protruding block 217 is not in contact with the recess A 210 at this time, the rotating block 209 will not be driven to rotate; when the threaded rod 204 rotates, it will drive the moving block 205 to move, since the moving block 205 can only move horizontally in the inner wall of the shell 1, the threaded rod 204 can be driven to rotate forward or reverse, which can drive the moving block 205 to move horizontally, when the moving block 205 moves to one side of the motor 203, the end of the connecting rod 206 hinged thereto moves synchronously, and the end of the connecting rod 206 hinged to the bottom plate 201 will flip up and lift the bottom plate 201, since one end of the bottom plate 201 is rotatably connected with the inner wall of the shell 1, the bottom plate 201 can be driven to flip up to an inclined state by the connecting rod 206, as shown in Figure 2 , so that the goods on the bottom plate 201 can be automatically slid off to facilitate unloading; when the threaded rod 204 is reversed to move the moving block 205 away from the motor 203, the bottom plate 201 will flip down to a horizontal state to load the goods; so when loading is needed, the side plates 202 on both sides can be lowered alone, and the bottom plate 201 remains in a horizontal state for loading, while when unloading, the side plates 202 on both sides can remain unchanged, and the bottom plate 201 can be lifted alone for unloading, which is more flexible, the operation steps are simple, and it is convenient to use.

[0033] As shown in Figure 6As shown, the limiting assembly 3 comprises a stopper 303 elastically connected in the inner wall of the back baffle 5 through a reset spring 302, and the outer wall of the stopper 303 is fixedly connected with a pull rod 301; the stopper 303 is slidingly connected with the inner wall of the back baffle 5, one end of the reset spring 302 is fixedly connected with the inner wall of the back baffle 5, and the other end of the reset spring 302 is fixedly connected with the outer wall of the stopper 303; the pull rod 301 penetrates through the outer wall of the back baffle 5, and the stopper 303 is in contact with the outer wall of the side plate 202.

[0034] With the above scheme: when the side plate 202 is in the vertical state, the stopper 303 is popped out under the elastic force of the reset spring 302, the straight surface of the stopper 303 is in contact with the outer wall of the side plate 202, the side plate 202 can be limited to keep the vertical state, when the moving rod 216 moves to the position where the convex block 217 is clamped with the groove B 211, the rotating block 209 cannot be limited to rotate, and the limiting assembly 3 can avoid the two groups of side plates 202 from being turned down; when it is needed to release the limitation of the side plate 202 and unfold the side plate 202 downward for loading, the pull rod 301 can be pulled to make the stopper 303 move to the inner wall of the back baffle 5 against the elastic force of the reset spring 302, so as to be separated from the outer wall of the side plate 202, at this time, the side plate 202 can be freely rotated, that is, the side plate 202 can be driven by the composite mechanism 2 to turn down and open; when the pull rod 301 is released, the reset spring 302 pushes the stopper 303 to return to the original position, the arc surface of the stopper 303 faces two sides, and in the process of turning up the side plate 202 to the vertical state, the arc surface of the stopper 303 is pressed to move to the inner wall of the back baffle 5, and after completely turning up to the vertical state, the stopper 303 is popped out to limit the side plate 202.

[0035] As shown in the figure, Figure 7 As shown, the stabilizing mechanism 4 comprises a stabilizing plate 401 elastically connected at the bottom end outer wall of the shell 1 through a telescopic spring 402, the top end outer wall of the stabilizing plate 401 is fixedly connected with a fixed rod 403, the outer wall of the fixed rod 403 is provided with a insertion slot 404, the outer wall of the fixed rod 403 is fixedly connected with a stepping plate 405, the outer wall of the shell 1 is fixedly connected with a fixed block 406, and the inner wall of the fixed block 406 is elastically connected with an insertion rod 408 through a compression spring 407; the fixed rod 403 is slidingly connected with the inner wall of the fixed block 406, the two ends of the telescopic spring 402 are fixedly connected with the outer walls of the shell 1 and the stabilizing plate 401 respectively, and the insertion rod 408 is clamped with the insertion slot 404; one end of the compression spring 407 is fixedly connected with the outer wall of the insertion rod 408, the other end of the compression spring 407 is fixedly connected with the inner wall of the fixed block 406, and the insertion rod 408 is slidingly connected with the inner wall of the fixed block 406.

[0036] Adopt the above scheme: the fixed rod 403 outer wall of the slot 404 is opened with two groups, the fixed block 406 inner wall of the plug rod 408 is provided with a slope, and the slope keeps the state of facing upwards, under the condition of not being affected by external force, the plug rod 408 is clamped with one of the groups of the slot 404, the fixed rod 403 can be limited, so that the position of the stabilizing plate 401 is fixed;The stabilizing plate 401 is provided with a plurality of rubber blocks below, which can improve the friction with the ground, when the shell 1 moves to transfer the logistics goods, the extension spring 402 keeps the stabilizing plate 401 in the state of being kept above and not being in contact with the ground due to its own elastic force, at this time, the plug rod 408 is clamped with the slot 404 below;The pedal 405 is fixed on the top outer wall of the fixed rod 403, which is convenient for the operator to adjust the position of the stabilizing plate 401 with the foot, and improves the convenience of operation;When it is necessary to adjust the position of the stabilizing plate 401, the pedal 405 can be pressed down, the fixed rod 403 moves downward synchronously, the slot 404 extrudes the slope of the plug rod 408, so that the plug rod 408 moves to the inner wall of the fixed block 406, thereby driving the stabilizing plate 401 to move downward and contact with the ground, the extension spring 402 is stretched under stress, the contact area of the whole device with the ground is improved, the stability of the shell 1 is increased, so as to avoid the possibility of being affected by external force when loading and unloading goods, which may cause damage to the goods due to side turning or dumping;After adjustment, the plug rod 408 corresponds to the position of the slot 404 above, the plug rod 408 is re-clamped into the slot 404 under the action of the compression spring 407, so that the stabilizing plate 401 will not move upward due to the elastic force of the extension spring 402;When it is necessary to remove the contact state of the stabilizing plate 401 with the ground, the plug rod 408 can be pulled outwards to be separated from the slot 404, the limiting of the fixed rod 403 is removed, the stabilizing plate 401 is automatically moved upward and reset due to the elastic force of the extension spring 402, so that the shell 1 can be pushed to transport goods.

[0037] The working principle and use process of the present application are as follows:

[0038] If loading is needed, the operator can first press the clamping block 214 to release the limiting of the moving rod 216, move the moving rod 216 to make the protrusion 217 clamped with the groove A 210, the clamping block 214 is clamped with another group of clamping grooves 215, then pull the pull rod 301 of the limiting assembly 3, make the blocking block 303 overcome the elastic force of the reset spring 302 to move to the inner wall of the back plate 5, separate from the contact with the outer wall of the side plate 202, at this time, the motor 203 can be started, the motor 203 drives the rotating shaft 212 to rotate, the rotating shaft 212 drives the rotating block 209 to rotate through the two groups of traction ropes 208 arranged in front and back staggered, the rotating block 209 drives the rotating wheels 207 on both sides to rotate at the same time, drives the two groups of side plates 202 to open at the same time, which is convenient for loading.

[0039] After the loading is completed, the motor 203 is started again to drive the output shaft to rotate the rotating shaft 212, so that the side plate 202 is flipped upward to the vertical state. At this time, the stop block 303 is popped out under the elastic force of the reset spring 302, and the straight surface of the stop block 303 is in contact with the outer wall of the side plate 202 to limit the side plate 202, so that the side plate 202 is kept in the vertical state to prevent the goods from falling during transportation. At this time, the shell 1 can be pushed to transport the logistics goods.

[0040] When the goods need to be unloaded at a suitable location, the operator can step down the pedal 405, and the fixed rod 403 is synchronously moved downward. The inclined surface of the insertion slot 404 is pressed against the insertion rod 408, so that the insertion rod 408 is moved into the inner wall of the fixed block 406, thereby driving the stabilizing plate 401 to move downward and contact the ground. The extension spring 402 is stretched under force, the contact area of the overall device with the ground is increased, and the stability of the shell 1 is improved.

[0041] Then, the clamping block 214 is pressed and the moving rod 216 is moved to another set of clamping slots 215 and clamping blocks 214. At this time, the protrusion 217 is clamped with the groove B 211. The motor 203 of the compound mechanism 2 is started to drive the threaded rod 204 to rotate, the threaded rod 204 rotates to drive the moving block 205 to move to one side of the motor 203, the connecting rod 206 synchronously moves the end hinged to the moving block 205, and the end of the connecting rod 206 hinged to the bottom plate 201 is flipped upward and lifts the bottom plate 201, so that the bottom plate 201 is flipped upward to the inclined state, and the goods are slid down to the ground along the inclined bottom plate 201 to complete the unloading. After the unloading is completed, the motor 203 is started to reverse the threaded rod 204, the moving block 205 moves away from the motor 203, and the bottom plate 201 is flipped downward to the initial horizontal state. The insertion rod 408 of the stabilizing mechanism 4 is pulled outward to be out of contact with the insertion slot 404, the limiting of the fixed rod 403 is released, and the extension spring 402 automatically moves upward to reset the stabilizing plate 401 due to its own elastic force. At this time, the transfer vehicle can continue the next transportation task.
