[0022] Initially, the lifting plate 40 is located on the ground below one side of the support platform 10. When luggage needs to be transported, the luggage can be placed on the plurality of conveying rollers 30 on the upper part of the lifting plate 40, and then the first driving assembly 50 is used to drive the lifting plate 40 to move upward, and then the plurality of conveying rollers 30 drive the luggage to move upward. When the lifting plate 40 moves up to the height where the conveying assembly 20 is located, the third driving assembly 70 drives the lifting plate 40 to rotate to an inclined state, and then drives the plurality of conveying rollers 30 to rotate to an inclined state. At this time, the luggage located on the upper part of the plurality of conveying rollers 30 can slide onto the conveying assembly 20 by itself, and then the luggage can be transported. The conveying assembly 20 continues to transport the luggage. When the luggage slides to the upper part of the conveying assembly 20, the first driving assembly 50 drives the lifting plate 40 to move downward, and then drives the plurality of conveying rollers 30 to move downward synchronously, thereby realizing the resetting of the lifting plate 40 and the plurality of conveying rollers 30 to further lift the subsequent luggage. Through the cooperation of the first driving assembly 50, the lifting plate 40, the plurality of conveying rollers 30 and the third driving assembly 70, the luggage to be transported can be automatically lifted onto the conveying assembly 20, avoiding manual placement of the luggage, thereby saving physical strength and improving the luggage transportation efficiency.

[0023] See also Figure 4 , Figure 5 as well as Figure 7 In one embodiment, an extended side plate 401 is fixedly provided on the side wall of the lifting plate 40, and the first driving assembly 50 includes a motor 501, a driving gear 502, a transmission gear 503, a screw rod 504 and a lifting plate 506. The motor 501 is fixedly installed at the bottom of the support platform 10, and the lifting plate 506 is arranged at the lower part of the extended side plate 401. The upper end of the screw rod 504 is rotatably connected to the bottom wall of the support platform 10, and the lower end passes through the extended side plate 401 and the lifting plate 506 in sequence and is threadedly matched with the lifting plate 506. The driving gear 502 is arranged at the output end of the motor 501, and the transmission gear 503 is fixedly arranged on the outside of the screw rod 504 and meshes with the driving gear 502.

[0024] After the luggage is placed on the plurality of conveying rollers 30, the motor 501 drives the driving gear 502 to rotate, and the meshing action of the driving gear 502 and the transmission gear 503 drives the lead screw 504 to rotate. When the lead screw 504 rotates, it drives the lifting plate 506 to move upward through the cooperation with the thread of the lifting plate 506. When the lifting plate 506 moves upward, it drives the extended side plate 401 to move upward, thereby driving the lifting plate 40, the plurality of conveying rollers 30 and the luggage to move upward, thereby realizing automatic lifting of the luggage.

[0025] See also Figure 4 as well as Figure 5In one embodiment, the first driving assembly 50 also includes a guide rod 505, the upper end of which is fixedly connected to the bottom wall of the support platform 10, and the lower end of which passes through the extended side plate 401 and the lifting plate 506 in sequence and movably cooperates with the lifting plate 506, and the guide rod 505 is parallel to the screw rod 504.

[0026] When the screw rod 504 rotates, through the active cooperation between the lifting plate 506 and the guide rod 505, the guide rod 505 can provide a guiding effect for the movement of the lifting plate 506, so that the lifting plate 506, the extended side plate 401, the lifting plate 40 and the luggage can move up smoothly.

[0027] See also Figure 1 , Figure 2 as well as Figure 5 Two groups of slots 402 are provided on the extension side panel 401, the screw rod 504 vertically passes through the extension side panel 401 from one group of slots 402, the guide rod 505 vertically passes through the extension side panel 401 from the other group of slots 402, the extension side panel 401 is hingedly arranged on the upper part of the lifting plate 506, the third driving assembly 70 includes a first top support rod, the first top support rod is fixedly mounted on the bottom wall of the support platform 10, and the first top support rod is located directly above the extension side panel 401.

[0028] As the screw rod 504 drives the extended side plate 401, the lifting plate 40 and the luggage to move upward, when the lifting plate 40 moves to the height of the conveying assembly 20, the upper part of the extended side plate 401 acts on the bottom of the first top support rod, and the first top support rod pushes the extended side plate 401, thereby driving the extended side plate 401 to rotate relative to the lifting plate 506. When the extended side plate 401 rotates, it drives the lifting plate 40 and the plurality of conveying rollers 30 to rotate toward the conveying assembly 20 as a whole to an inclined state, so that the luggage on the plurality of conveying rollers 30 can slide onto the conveying assembly 20 by itself, and then be transported by the conveying assembly 20. When the extended side plate 401 rotates relative to the lifting plate 506, the screw rod 504 and the guide rod 505 are adaptively deflected inside the corresponding notches 402; when the luggage slides When it reaches the conveying assembly 20, the motor 501 drives the driving gear 502 to rotate in the opposite direction, and the lifting plate 506 is driven to move downward through the reverse meshing action of the driving gear 502 and the transmission gear 503, and the lifting plate 506 drives the extended side plate 401 to move downward. At this time, the extended side plate 401 rotates in the opposite direction compared with the lifting plate 506 under the action of gravity, thereby driving the lifting plate 40 and a number of conveying rollers 30 to rotate in the opposite direction. When the extended side plate 401 is re-connected to the upper part of the lifting plate 506, the extended side plate 401 stops reversing, and the lifting plate 40 and a number of conveying rollers 30 remain horizontal. As the screw rod 504 continues to rotate in the opposite direction, it drives the extended side plate 401, the lifting plate 40 and a number of conveying rollers 30 to continue to move downward, thereby realizing the resetting of the lifting plate 40 and a number of conveying rollers 30.

[0029] See also Figure 1 as well as Figure 6 In one embodiment, a rotating shaft 302 is fixedly provided at the end of each group of the conveying rollers 30 , and a support seat 301 is rotatably provided at one end of the rotating shaft 302 away from the conveying rollers 30 , and the support seat 301 is fixedly installed on the upper part of the lifting plate 40 .

[0030] The support seat 301 provides rotation support for the rotating shaft 302, so that after the plurality of conveying rollers 30 rotate to the inclined state following the lifting plate 40, the luggage on the upper part of the plurality of conveying rollers 30 can smoothly slide onto the conveying assembly 20, and the plurality of conveying rollers 30 can rotate adaptively.

[0031] See also Figure 1 as well as Figure 2In one embodiment, a limit assembly 80 is further provided on the lifting plate 40. When the screw rod 504 rotates to drive the lifting plate 40 and the plurality of conveying rollers 30 to move upward, the limit assembly 80 is used to limit the rotation of the plurality of conveying rollers 30, so that the luggage is kept stable on the upper part of the plurality of conveying rollers 30. A second driving assembly 60 is further provided at the bottom of the support platform 10. When the first top support rod pushes the extending side plate 401 to drive the lifting plate 40 to rotate relative to the lifting plate 506, the second driving assembly 60 is used to drive the limit assembly 80 to move, so as to release the rotation restriction of the plurality of conveying rollers 30, so that the plurality of conveying rollers 30 can smoothly convey the luggage thereon to the conveying assembly 20.

[0032] See also Figure 2 as well as Figure 6 In one embodiment, a slideway 403 is provided inside the lifting plate 40, the second driving assembly 60 includes a second top support rod, and the second top support rod is fixedly arranged at the bottom of the support platform 10, the limiting assembly 80 includes a limiting gear 801, a limiting rod 803, a first elastic member 804, a push plate 805, a second elastic member 806, a slide rod 807 and a wedge block 808, and the limiting gear 801 is provided with a plurality of groups corresponding to the rotating shaft 302, and a plurality of the limiting gears 801 are fixedly arranged outside the plurality of the rotating shafts 302, and the limiting rods 803 are provided with a plurality of groups corresponding to the limiting gears 801, and the upper ends of the plurality of limiting rods 803 extend to two adjacent groups of the corresponding limiting gears 801. The teeth are arranged between the teeth, and the lower end passes through the lifting plate 40 and extends to the inside of the slide 403. An annular stopper 802 is fixedly arranged on the outside of each group of the limiting rods 803. Each group of the annular stopper 802 is connected to the lifting plate 40 through a group of the first elastic members 804. One end of the sliding rod 807 extends to the inside of the slide 403, and the other end extends to the outside of the lifting plate 401 and is connected to the push plate 805. The sliding rod 807 is located in the rod body of the slide 403 and is fixed with a plurality of wedge blocks 808. The plurality of wedge blocks 808 correspond to the plurality of limiting rods 803 one by one. One end of the second elastic member 806 is connected to the side wall of the lifting plate 40, and the other end is connected to the push plate 805.

[0033] When the screw rod 504 rotates to drive the lifting plate 40 and the plurality of conveying rollers 30 to move upward, the second elastic member 806 elastically supports the push plate 805, so that the lower ends of the plurality of limit rods 803 are respectively abutted against the inclined surfaces of the plurality of wedge blocks 808. At this time, the upper ends of the plurality of limit rods 803 are respectively inserted between two adjacent sets of teeth of the plurality of limit gears 801, thereby limiting the rotation of the rotating shaft 302 and the conveying roller 30, so that the luggage on the upper part of the conveying roller 30 can be kept in the process of moving upward. When the first top support rod pushes the extended side plate 401 to drive the lifting plate 40 to rotate relative to the lifting plate 506, the lifting plate 40 drives the slide bar 807 and the push plate 805 to rotate. When the push plate 805 rotates, it acts on the side wall of the second top support rod. The second top support rod pushes the push plate 805, thereby causing the slide bar 807 to move inside the slideway 403. When the slide bar 807 moves, it drives the plurality of wedge blocks 808 to move. When the plurality of wedge blocks 808 move, the plurality of first elastic members 804 pull the plurality of limit rods 803 so that The plurality of limit rods 803 move downward, so that the upper ends of the plurality of limit rods 803 are removed from between the corresponding two sets of teeth, thereby releasing the rotation restriction of the plurality of limit gears 801. At this time, the plurality of conveying rollers 30 can roll and convey the luggage thereon, so that the luggage is smoothly conveyed to the upper part of the conveying assembly 20. When the luggage is conveyed to the upper part of the conveying assembly 20, as the screw rod 504 rotates in the reverse direction, the lifting plate 40 rotates in the reverse direction under the action of gravity, thereby driving the sliding rod 807 and the push plate 805 to rotate in the reverse direction. The push plate 805 is rotated in the direction of rotation, and is separated from the side wall of the second top support rod. The second elastic member 806 pushes the push plate 805 so that the slide rod 807 moves toward the outside of the lifting plate 40, thereby driving the plurality of wedge blocks 808 to move in the opposite direction. The plurality of wedge blocks 808 push the plurality of limit rods 803 so that the plurality of limit rods 803 move upward compared to the lifting plate 40, thereby allowing the upper ends of the plurality of limit rods 803 to be reinserted between two adjacent sets of teeth of the plurality of limit gears 801, thereby restricting the rotation of the plurality of conveying rollers 30 again.

[0034] See also Figure 6 In one embodiment, a curved baffle plate 303 is fixedly provided on one side of each group of the support seats 301 facing the conveying rollers 30, and the curved baffle plate 303 is used to cover the limiting gear 801 therein, thereby preventing the luggage from sliding along the upper part of the conveying rollers 30 and driving the conveying rollers 30 to rotate, and preventing the luggage from being stuck in the gap between the conveying rollers 30 and the support seats 301, and then being damaged by the rotating limiting gear 801.

[0035] In one embodiment, the first elastic member 804 and the second elastic member 806 may be springs or metal springs, which are not limited herein.

[0036] In one embodiment, the conveying assembly 20 may be a belt conveyor or a roller conveyor, which is not limited here.

[0037] The working principle of the present invention is as follows: Initially, the lifting plate 40 is located on the ground below one side of the support platform 10 and remains in a horizontal state. At this time, the plurality of limit rods 803 are supported by the plurality of wedge blocks 808, so that the upper ends of the plurality of limit rods 803 are respectively inserted between two adjacent sets of teeth of the plurality of limit gears 801, thereby limiting the rotation of the plurality of conveying rollers 30. When it is necessary to transport the luggage, the luggage can be placed on the plurality of conveying rollers 30 on the upper part of the lifting plate 40, and then the motor 501 is started, and the motor 501 drives the driving gear 502 to rotate. The meshing action of the driving gear 502 and the transmission gear 503 drives the screw rod 504 to rotate, and the screw rod 504 and the lifting plate 506 cooperate with each other through the threaded action of the screw rod 504 to drive the lifting plate 506, the extension side plate 401, the lifting plate 40, the plurality of conveying rollers 30 and the luggage to move upward as a whole. When the lifting plate 40 moves to the height where the conveying assembly 20 is located, the first top support rod acts on the upper part of the extension side plate 401, thereby driving the extension side plate 401 to rotate relative to the lifting plate 506, and the extension side plate 401 drives the lifting plate 40, the plurality of conveying rollers 30 and the luggage to move upward. The luggage is rotated to the tilted state as a whole. At the same time, the push plate 805 acts on the side wall of the second top support rod. The second top support rod pushes the push plate 805 to make the slide bar 807 move into the slideway 403, thereby taking the wedge blocks 808 away from the bottom of the limit rods 803. At this time, the first elastic member 804 pulls the limit rods 803 downward, thereby releasing the rotation restriction of the conveying rollers 30, so that the luggage can automatically slide from the upper part of the tilted conveying rollers 30 to the upper part of the conveying assembly 20, thereby realizing the automatic lifting of the luggage. After the lifting is completed, the motor 501 drives the driving gear 502 to rotate in the opposite direction, and the lifting plate 506 is driven downward by the reverse meshing action of the driving gear 502 and the transmission gear 503 and the reverse threaded cooperation action of the lead screw 504 and the lifting plate 506. The extended side plate 401 and the lifting plate 40 rotate downward under the action of their own gravity. When the extended side plate 401 is re-connected to the upper part of the lifting plate 506, the extended side plate 401, the lifting plate 40 and a number of conveying rollers 30 move downward in a horizontal posture as a whole, thereby realizing the resetting of the lifting plate 40.

[0038] In the embodiment of the present invention, initially, the lifting plate 40 is located on the ground below one side of the support platform 10. When luggage needs to be transported, the luggage can be placed on the plurality of conveying rollers 30 on the upper part of the lifting plate 40, and then the first driving assembly 50 is used to drive the lifting plate 40 to move upward, and then the plurality of conveying rollers 30 are used to drive the luggage to move upward. When the lifting plate 40 moves up to the height where the conveying assembly 20 is located, the third driving assembly 70 drives the lifting plate 40 to rotate to an inclined state, and then drives the plurality of conveying rollers 30 to rotate to an inclined state. At this time, the luggage located on the upper part of the plurality of conveying rollers 30 can slide onto the conveying assembly 20 by itself, and the conveying assembly 20 continues to transport the luggage. When the luggage slides to the conveying assembly 20, After the luggage is lifted up, the first driving assembly 50 drives the lifting plate 40 to move downward, and then drives the plurality of conveying rollers 30 to move downward synchronously, thereby realizing the resetting of the lifting plate 40 and the plurality of conveying rollers 30 to further lift the subsequent luggage; through the cooperation of the first driving assembly 50, the lifting plate 40, the plurality of conveying rollers 30 and the third driving assembly 70, the luggage to be transported can be automatically lifted to the conveying assembly 20, avoiding manual placement of the luggage, thereby saving physical strength and improving the luggage transportation efficiency. Compared with the prior art, when transporting luggage, there is no need to manually lift the luggage, and the luggage can be automatically lifted to the conveying assembly 20, thereby saving physical strength and improving the luggage transportation efficiency.
