[0062] To make the objectives, technical solutions, and advantages of this application more clearly understood, the present application is further described below with reference to the accompanying drawings and examples. It is apparent that the described examples are only a portion of the embodiments of this application, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the examples in this application are intended to fall within the scope of protection of this application.

[0063] AVG vehicles can be used in smart logistics. Their top pallets are used to carry containers. AVG vehicles typically travel on uneven roads, both inside and outside warehouses. If the AVG vehicle is moving containers too quickly, the containers can easily fall off the pallet.

[0064] The main purpose of the embodiment of this solution is to solve the problem of AVG vehicles swaying and shaking during the transportation of material boxes, which causes the material boxes to shift, deflect and overturn on the material box pallet, and to improve the stability of the AVG vehicles during the transportation of material boxes.

[0065] To this end, the present application proposes an AVG vehicle and a material box carrying mechanism thereof.

[0066] Specifically, a material box carrying mechanism of an AVG vehicle according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0067] Figure 1 is a schematic diagram of the top axonometric structure of a container carrying mechanism of an AVG vehicle in a flattened state according to an embodiment of the present application, Figure 2 is a schematic diagram of the bottom axonometric structure of the container carrying mechanism of an AVG vehicle in a flattened state according to an embodiment of the present application, and Figure 3 is a schematic diagram of the top axonometric structure of the container carrying mechanism of an AVG vehicle in an outwardly turned state according to an embodiment of the present application. The container carrying mechanism of an AVG vehicle of the embodiment of the present application can be applied to an AVG vehicle, with its top portion being used to grip a container and transport it in the field of intelligent logistics.

[0068] As shown in FIG. 1 , FIG. 2 and FIG. 3 , the container carrying mechanism 100 of the AVG vehicle includes a container pallet 10 and two turning mechanisms 20 .

[0069] The container pallet 10 has opposing top and bottom surfaces 10a and 10b. Clamp mounting openings 11 are defined on opposing edges of the container pallet 10. Each flip mechanism 20 comprises a sequentially connected clamping section 211, a straight section 212, and a barbed section 213. The clamping section 211 of the flip mechanism 20 is positioned near the edge of the container pallet 10, while the barbed section 213 is positioned near the inside of the container pallet 10. The clamping section 211 bends upward, forming a first bend 201 with the straight section 212. The barbed section 213 bends downward, forming a second bend 202 with the straight section 212. The straight section 212 of each flipping mechanism 20 is rotatably connected to the two side walls of the clamp mounting opening 11 on the corresponding side of the material box pallet 10, and the flipping mechanism 20 is eccentrically arranged so that when the material box carrying mechanism 100 is not carrying a material box, the first bent portion 201 is lower than the bottom surface 10b of the material box pallet 10, and the second bent portion 202 is higher than the top surface 10a of the material box pallet 10.

[0070] In the technical solution provided by the embodiment of this solution, the container carrying mechanism 100 of the AVG vehicle has claw mounting openings 11 formed on opposite sides of the container pallet 10. The two flipping mechanisms 20 each include a claw section 211, a straight section 212, and a barb section 213 connected in sequence. The claw section 211 of the flipping mechanism 20 is located near the edge of the container pallet 10, and the barb section 213 is located near the inside of the container pallet 10. A first bend 201 is formed between the claw section 211 and the straight section 212, and a second bend 202 is formed between the barb section 213 and the straight section 212. The straight section 212 of each flipping mechanism 20 is rotatably connected to the two side walls of the claw mounting opening 11 on the corresponding side of the container pallet 10, and the flipping mechanism 20 is eccentrically disposed. When the container carrying mechanism 100 is not carrying a container, the first bent portion 201 is lower than the bottom surface 10b of the container pallet 10, and the second bent portion 202 is higher than the top surface 10a of the container pallet 10. When the container carrying mechanism 100 is carrying a container, when the container is placed on the container pallet 10, the container presses down on the second bent portions 202 on both sides of the top surface 10a of the container pallet 10, causing the clamping claws 211 of the two flipping mechanisms 20 to flip inward toward the container pallet 10, clamping the container and improving the stability of the AVG vehicle during container transport.

[0071] The container is typically a rectangular box with an open top and internal space for placing materials. The bottom of the rectangular box presses down on the second bent portion 202 of the two tilting mechanisms 20, which is higher than the top surface 10a of the container support plate 10. The gripping claws 211 of the tilting mechanisms 20 on either side of the container support plate 10 clamp onto the side walls of the rectangular box. The specific process of clamping the container when the container support mechanism 100 is used in an AVG vehicle can be found in the detailed description of the process in the accompanying drawings in the following AVG vehicle embodiment.

[0072] The container support plate 10 can be a flat plate, specifically made of metal, with the required strength to support the container. The opening dimensions of the gripper mounting opening 11 match those of the tilting mechanism 20. The gripper mounting opening 11 can be a rectangular slot that opens laterally to the container support plate 10.

[0073] FIG4 is an enlarged view of A in FIG2 . As shown in FIG2 and FIG4 , in the implementation of the rotatable connection between the flip mechanism 20 and the container pallet 10, in some embodiments, each flip mechanism 20 further includes: a shaft 22 and at least one shaft sleeve 23. The at least one shaft sleeve 23 is sleeved on the shaft 22, and the ends of the shaft 22 are fixedly mounted on the two side walls of the clamp mounting opening 11. The shaft sleeve 23 is disposed on the lower surface of the straight section 212, so that the straight section 212 and the at least one shaft sleeve 23 rotate synchronously on the shaft 22.

[0074] When there is only one sleeve 23 , it can be disposed in the middle of the clamping jaw mounting opening 11 .

[0075] When there are two shaft sleeves 23, the two shaft sleeves 23 can be installed on both sides of the clamping jaw installation opening 11. When the material box presses down on the second bent portions 202 on both sides of the top surface 10a of the material box support plate 10, the straight section 212 and the two shaft sleeves 23 rotate synchronously on the shaft 22, so that the clamping jaw sections 211 of the two turning mechanisms 20 clamp the material box.

[0076] AVG vehicles may encounter bumpy roads when transporting containers. Similarly, AVG vehicles may encounter bumpy roads when moving empty. During this bumpy ride, the outward-turned tilting mechanism 20 may be affected by the bumpy road conditions and tilt inward too much, preventing it from returning to its outward-turned position.

[0077] Figure 5 is a schematic diagram of the bottom axonometric structure of the container carrying mechanism 100 of an AVG vehicle in a flattened state according to another embodiment of the present application. Figure 6 is a schematic diagram of the top axonometric structure of the container carrying mechanism 100 of an AVG vehicle in an outward-turned state according to another embodiment of the present application. Figure 7 is a schematic diagram of the bottom axonometric structure of the container carrying mechanism 100 of an AVG vehicle in an outward-turned state according to another embodiment of the present application. Figure 8 is an enlarged view of area B in Figure 7 . As shown in Figures 5, 6, 7, and 8, to address the aforementioned issues, in some embodiments of the present solution, each tilting mechanism 20 further includes a stop plate 24. The upper surface of the sleeve 23 is disposed on the lower surface of the straight section 212, and the lower surface of the sleeve 23 is disposed on the upper surface of the stop plate 24, enabling the straight section 212, the stop plate 24, and at least one sleeve 23 to rotate synchronously on the shaft 22. When the claw section 211 of the flipping mechanism 20 flips toward the inner side of the material box pallet 10, so that the second bending portion 202 is lower than the top surface 10a of the material box pallet 10 by a preset distance, the limit stop plate 24 contacts the bottom surface 10b of the material box pallet 10 to limit the inner flipping angle of the flipping mechanism 20.

[0078] The angle at which the inner side of the turning mechanism 20 is limited by the limit stop plate 24 can be determined according to the distance between the limit stop plate 24 and the bottom surface 10 b of the material box support plate 10 .

[0079] As shown in Figures 6, 7, and 8, to facilitate the connection of the sleeve 23 to the straight section 212 and the stop plate 24, respectively, the sleeve 23 may be a rectangular block having an axial hole. The upper surface of the rectangular block serves as the top surface of the sleeve 23, and the lower surface of the rectangular block serves as the bottom surface of the sleeve 23. The sleeve 23 is rotatably mounted on the shaft 22 through the axial hole. The upper surface of the rectangular block is flat, allowing for convenient alignment with the flat surface of the straight section 212. The lower surface of the rectangular block is flat, allowing for convenient alignment with the flat surface of the stop plate 24. This flat alignment structure can accommodate high torque conditions, allowing the straight section 212, the stop plate 24, and the sleeve 23 to rotate stably and synchronously on the shaft 22.

[0080] Specifically, both sides of the limit stop plate 24 extend to the side wall edges on both sides of the clamp mounting opening, that is, the length of the limit stop plate 24 is greater than the opening length of the clamp mounting opening, so that when the straight section 212, the limit stop plate 24 and the shaft sleeve 23 rotate synchronously on the shaft rod 22, the two sides of the limit stop plate 24 can contact the side wall edges on both sides of the clamp mounting opening to limit the inner flipping angle of the flipping mechanism 20.

[0081] As shown in Figures 5 and 6, in the specific assembly process, each flip mechanism 20 also includes: two shaft screws 251, a claw screw 252, and a stop plate screw 253. The two shaft screws 251 pass through the material box pallet 10 from the top surface 10a of the material box pallet 10 and are locked with the threaded holes at both ends of the shaft 22. The claw screw 252 passes through the straight section 212 and is locked with the threaded holes on the first surface of the rectangular block. The stop plate screw 253 passes through the limit stop plate 24 and is locked with the threaded holes on the second surface of the rectangular block. The screw connection method can conveniently, quickly and stably connect the straight section 212, the limit stop plate 24 and the shaft sleeve 23, and connect the material box pallet 10 and the shaft 22. Specifically, the nut end face of the shaft screw 251 is flush with the top surface 10a of the material box pallet 10. The top surface of the nut of the claw screw 252 is flush with the top surface of the straight section 212. The top surface of the nut of the stop plate screw 253 is flush with the bottom surface of the limit stop plate 24. There can be four claw screws 252 and four stop plate screws 253. Two claw screws 252 and two stop plate screws 253 are used to connect one shaft sleeve 23. Two claw screws 252 and two stop plate screws 253 are used to connect another shaft sleeve 23.

[0082] When an AVG vehicle is moving unladen and encounters bumpy road conditions, the tilting mechanism 20 may be affected by the bumpy road conditions and may not only tilt inward but also tilt outward and sway, causing the second bent portion 202 to "jump" up and down. Figure 9 is a top isometric view of the inward-turned state of the container support mechanism 100 of an AVG vehicle according to another embodiment of the present application. Figure 10 is a bottom isometric view of the inward-turned state of the container support mechanism 100 of an AVG vehicle according to another embodiment of the present application. Figure 11 is an enlarged view of C in Figure 10. As shown in Figures 9, 10, and 11, to address the aforementioned outward tilting and swaying issue, a stopper 214 is formed extending from at least one side of the end of the barbed section 213. When the container carrying mechanism 100 is not carrying a container, the end of the barb segment 213 extends from the clamping jaw installation opening 11 to one side of the bottom surface of the container pallet, and the stopper 214 abuts against the bottom surface 10b of the container pallet 10 to limit the angle at which the clamping jaw segment 211 of the flipping mechanism 20 flips toward the outside of the container pallet 10. Specifically, a stopper 214 may extend from both sides of the end of the barb segment 213, and the two stoppers 214 abut against the side walls of the clamping jaw installation opening 11 of the container pallet 10.

[0083] As shown in Figure 8 , in the eccentric configuration of the flipping mechanism 20, to achieve an offset between the center of mass of the flipping mechanism 20 and the axis of the flipping mechanism 20, multiple lightening holes 203 can be provided on the straight section 212 and the barbed section 213 on the side away from the center of mass of the flipping mechanism 20. The multiple lightening holes 203 can be arranged as a plurality of elongated holes in a row to facilitate machining. The opening area of ​​the lightening holes 203 is determined by the desired center of mass position.

[0084] In the preparation of the flipping mechanism 20, the clamping jaw section 211, the straight section 212, and the barb section 213 are formed by bending a sheet metal having the plurality of weight-reducing holes 203. Specifically, a plurality of weight-reducing holes 203 can be first formed at predetermined locations on a flat sheet metal, where the predetermined locations correspond to the weight-reducing locations of the straight section 212 and the barb section 213. Then, the sheet metal having the plurality of weight-reducing holes 203 is bent twice to form the clamping jaw section 211, the straight section 212, and the barb section 213. Compared to the flipping mechanism 20 prepared entirely through machining, the use of a bending process to prepare the clamping jaw section 211, the straight section 212, and the barb section 213 is simple, convenient, and quick.

[0085] As shown in Figures 1 and 8, the clamping claw section 211 is usually made of metal material with a relatively smooth surface. When clamping the material box, the friction force generated is limited. In some embodiments of the present solution, the flipping mechanism 20 also includes: two anti-slip films 26. The two anti-slip films 26 are respectively arranged on the opposite gripping surfaces of the clamping claw sections 211 of the two flipping mechanisms 20. The anti-slip films 26 can be made of anti-slip materials such as rubber and silicone. The anti-slip films 26 can be glued to the gripping surface of the clamping claw section 211. The two opposite anti-slip films 26 can form a good gripping effect on both sides of the material box.

[0086] FIG12 is a schematic diagram of the bottom axonometric structure of a material box supporting the material box carrying mechanism 100 of an AVG vehicle according to another embodiment of the present application. As shown in FIG6, FIG9 and FIG12, in the related art, the material box is usually rectangular. If two opposing clamping claw sections 211 are used to clamp the two sides of the material box, the material box can only be limited on both sides, but cannot be effectively limited in the front and rear directions. In some embodiments provided by this solution, the material box carrying mechanism 100 of the AVG vehicle mentioned above also includes: a guide stop block 271. The guide stop block 271 is set at the center of the top surface 10a of the material box support plate 10, and the top surface edge of the guide stop block 271 has a guide cut angle. The guide stop block 271 is used to cooperate with the stop hole 901 set on the bottom plate of the material box 900 to limit the position. Specifically, the guide stop block 271 can be fixed to the top surface 10a of the material box support plate 10 by a stop block bolt.

[0087] When the material box is placed on the material box pallet 10, the stop circular hole 901 at the bottom of the material box 900 can be easily inserted into the stop circular hole 901 under the guidance of the guide angle of the top edge of the guide stop circular block 271, thereby limiting the movement of the material box 900 in the front and rear directions of the material box pallet 10. The cooperation of the two flipping mechanisms 20 and the guide stop circular block 271 can limit the material box 900 on the material box pallet 10 in the lateral directions and the front and rear directions. Compared with the material box supporting mechanism 100 using a set of flipping mechanisms 20 on the left rear and front and back, the embodiment of this solution can save the flipping mechanisms 20 on the front and rear sides, thereby simplifying the structural complexity of the material box supporting mechanism 100 and reducing production costs.

[0088] As shown in Figure 5, when the material box carrying mechanism 100 is used in an AVG vehicle, it needs to adapt to the receiving operation of materials at multiple height positions. In practice, the bottom of the material box pallet 10 needs to be connected to the scissors-type lifting mechanism 300 to achieve the height adjustment of the material box pallet 10. Specifically, the bottom surface 10b of one side of the material box pallet 10 is provided with a scissors-type lifting hinge seat 281, and the scissors-type lifting hinge seat 281 is provided with a hinge hole, and the hinge hole is used to be hinged with the hinge end at the top of the scissors-type lifting mechanism 300. The bottom surface 10b of the other side of the material box pallet 10 is provided with a scissors-type lifting sliding seat 282, and the scissors-type lifting sliding seat 282 is provided with a sliding hole. The sliding hole is used to be slidably connected with the sliding end at the top of the scissors-type lifting mechanism 300.

[0089] Specifically, an AVG vehicle according to an embodiment of the present application will be described below with reference to the accompanying drawings. Figure 13 is a schematic diagram of the axonometric structure of an AVG vehicle according to yet another embodiment of the present application, and Figure 14 is a schematic diagram of the front view of an AVG vehicle according to yet another embodiment of the present application. As shown in Figures 13 and 14, the AVG vehicle according to yet another embodiment of the present application includes the container carrying mechanism 100 of the AVG vehicle described in the above embodiments.

[0090] In the technical solution provided by the embodiment of this solution, the container carrying mechanism 100 of the AVG vehicle has claw mounting openings 11 formed on opposite sides of the container pallet 10. The two flipping mechanisms 20 each include a claw section 211, a straight section 212, and a barb section 213 connected in sequence. The claw section 211 of the flipping mechanism 20 is located near the edge of the container pallet 10, and the barb section 213 is located near the inside of the container pallet 10. A first bend 201 is formed between the claw section 211 and the straight section 212, and a second bend 202 is formed between the barb section 213 and the straight section 212. The straight section 212 of each flipping mechanism 20 is rotatably connected to the two side walls of the claw mounting opening 11 on the corresponding side of the container pallet 10, and the flipping mechanism 20 is eccentrically disposed. When the container carrying mechanism 100 is not carrying a container, the first bent portion 201 is lower than the bottom surface 10b of the container pallet 10, and the second bent portion 202 is higher than the top surface 10a of the container pallet 10. When the container carrying mechanism 100 is carrying a container, when the container is placed on the container pallet 10, the container presses down on the second bent portions 202 on both sides of the top surface 10a of the container pallet 10, causing the clamping claws 211 of the two flipping mechanisms 20 to flip inward toward the container pallet 10, clamping the container and improving the stability of the AVG vehicle during container transport.

[0091] In a specific embodiment, the AVG vehicle further includes a vehicle body 200 and a scissor lift mechanism 300. One side of the lower arm of the scissor lift mechanism 300 is hinged to the hinged end of the vehicle body 200, while the other side of the lower arm of the scissor lift mechanism 300 is slidably connected to a sliding seat on the vehicle body 200. One side of the upper arm of the scissor lift mechanism 300 is hinged to a hinge hole in the scissor lift hinge seat 281 at the bottom of the container pallet 10, while the other side of the upper arm of the scissor lift mechanism 300 is slidably connected to a sliding hole in the scissor lift hinge seat 281 at the bottom of the container pallet 10.

[0092] FIG15 is a diagram illustrating a state in which the flipping mechanism 20 of an AVG vehicle according to another embodiment of the present application is not in contact with the container, FIG16 is a diagram illustrating a state in which the flipping mechanism 20 of an AVG vehicle according to another embodiment of the present application is initially in contact with the container, FIG17 is a diagram illustrating a state in which the flipping mechanism 20 of an AVG vehicle according to another embodiment of the present application is in the process of contacting the container, and FIG18 is a diagram illustrating a state in which the flipping mechanism 20 of an AVG vehicle according to another embodiment of the present application is gripping the container. As shown in FIG15 , FIG16 , FIG17 and FIG18 , as the scissor-type lifting mechanism 300 continuously lifts the container pallet 10, gradually bringing the container pallet 10 closer to and lifting the container 900, as shown in FIG15 , when the container 900 and the two flipping mechanisms 20 are not in contact, the two flipping mechanisms 20 of the container support mechanism 100 are in an outward-turned state under the action of gravity. As shown in Figure 16, when the container pallet 10 approaches and lifts the container 900, the second curved portion 202, which is higher than the top surface 10a of the container pallet 10, will preferentially contact the bottom of the container 900, immediately guiding and clamping the container 900 and improving the efficiency of clamping the container 900. As shown in Figure 17, as the container pallet 10 continues to rise, the container 900 presses down on the second curved portion 202, causing the two tilting mechanisms 20 of the container support mechanism 100 to gradually tilt inward, and the two clamping jaws 211 to move toward the sides of the container 900. As shown in Figure 18, when the top surface 10a of the container pallet 10 and the bottom of the container 900 are fully in contact, the two clamping jaws 211 clamp onto both sides of the container 900, completing the gripping action. Simultaneously, the guide stop 271 of the container pallet 10 can be easily inserted into the stop hole 901 at the bottom of the container 900. Thereby, the material box carrying mechanism 100 limits the material box 900 in the left and right directions and the front and back directions, reducing the probability of the material box 900 being shifted, deflected or even overturned on the material box pallet 10.

[0093] The AVG vehicle provided in this embodiment can address the issues of swaying, deflection, and tipping of the container 900 during transport by the AVG vehicle, thereby better protecting the safety of items or materials within the container 900. Furthermore, the overall structure of the clamping jaw section 211, straight section 212, and barbed section 213 is simple, and the production process is easy to implement, significantly reducing production costs. Furthermore, the ease of assembly and maintenance is minimal, reducing maintenance costs and time for the AVG vehicle, thereby creating greater value for businesses.

[0094] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
