[0044] In the related art, a paper pallet, also known as a paper tray or cardboard pallet, is a type of pallet product mainly made of paper materials such as pulp, corrugated cardboard, and honeycomb cardboard, and is manufactured through processes such as die-cutting, folding, gluing, and stapling for carrying goods and for logistics turnover. As an environmentally friendly, lightweight, and economical packaging solution, paper pallets are widely used in industries such as food, beverage, medicine, electronic products, daily chemicals, and logistics warehousing. In particular, the single-sided paper pallet with only one load-bearing surface is the most widely used, suitable for manual handling or stacking, and is commonly used in supermarket shelf displays, express delivery packaging, etc. With its advantages of environmental protection, light weight, low cost, and easy recycling, the paper pallet has become an important part of modern logistics packaging. Moreover, with the rapid development of the logistics industry and the increasing environmental protection requirements, the application prospect of the paper pallet will continue to be broad.

[0045] When packaging products with heavy weight and large volume, such as common mobile robots, intelligent devices, etc., a five-sided box combined with a paper pallet is mostly used for packaging. Among them, the paper pallet is formed by stapling or gluing, and after forming, it is not detachable, and there is a certain height difference from the ground after forming. When packing, multiple people need to lift the product to a certain height and then put it into or take it out of the paper pallet, which is inconvenient to operate and has low packaging efficiency.

[0046] Such as Figure 1 AndFigure 2 As shown, to solve the above technical problems, an embodiment of the present application provides a paper tray, which includes a paper tray body and a locking member. The paper tray body has a bottom plate 100 and a plurality of folding side plates, and the plurality of folding side plates are sequentially arranged along the circumference of the bottom plate 100. Among them, the plurality of folding side plates can be folded to a closed state, so that the bottom plate 100 and the plurality of folding side plates can enclose to form a tray structure. The locking member is connected to the paper tray body, and the locking member can limit the folding side plates to keep them in the closed state.

[0047] In this embodiment, a large mobile robot is taken as an example for packaging. Of course, the product to be packaged can also be of other types, such as washing machines, refrigerators, televisions, etc., which are not specifically limited here.

[0048] In actual operation, the paper tray body is kept in the unfolded state, that is, the paper tray is placed on the ground. Subsequently, the large mobile robot is moved to the bottom plate 100 of the paper tray. After the large mobile robot is in place, the plurality of folding side plates are folded to the closed state, and all the folding side plates are fixed and limited by the locking member to keep them in the closed state, that is, to form a tray structure.

[0049] It should be noted that when unpacking and taking goods, by releasing the limitation of the locking member on the plurality of folding side plates, rapid disassembly can be completed, and the paper tray body is in the unfolded state. Repeating the above moving process can take out the large mobile robot.

[0050] Obviously, keeping the paper tray in the unfolded state is beneficial for loading and unloading goods. Even when the goods product does not have moving rollers, it is not necessary for the staff to lift the goods product significantly, and the disassembly and assembly difficulty is lower.

[0051] Of course, by way of example, the locking member is selected as a convenient disassembly and assembly component, which can further improve the packing and unpacking efficiency. For example, the locking member is selected as a snap structure, a bolt and nut structure, etc., which are not specifically limited here.

[0052] By way of example, in this embodiment, the structural shape of the paper tray can be square. Of course, in other embodiments, the structural shape of the paper tray is set as triangular, pentagonal, hexagonal, heptagonal, etc., which are not specifically limited here. Among them, the number of folding side plates determines the structural shape of the paper tray. For example, when the number of folding side plates is three, the corresponding structural shape of the paper tray is triangular; when the number of folding side plates is four, the corresponding structural shape of the paper tray is quadrilateral or square; when the number of folding side plates is five, the corresponding structural shape of the paper tray is pentagonal, etc.

[0053] Of course, specifically how to select the shape of the paper tray can be set according to the shape of the product to be actually packaged. For example, when the shape of the product to be packaged is similar to a triangular prism, the structural shape of the paper tray is set to a triangle, thereby improving the fit between the product to be packaged and the paper tray and facilitating the increase of stability. Or, when the shape of the product to be packaged is similar to a quadrangular prism, the structural shape of the paper tray is set to a square.

[0054] Exemplarily, the entire paper tray body can be processed by conventional cutting processes.

[0055] By applying the paper tray provided by the present utility model, the product can be moved to the bottom plate 100, and then a plurality of folding side plates are folded to a closed state, and the positions of the plurality of folding side plates are locked by locking members, so that the plurality of folding side plates are kept in the closed state, so that the product is located within the tray structure formed by the plurality of folding side plates and the bottom plate 100, completing the packaging. The entire packaging process does not require manual lifting of large products, simplifies the packaging operation, saves time and effort, and can improve the packaging efficiency.

[0056] As Figure 2 shown, in some embodiments, the locking member includes a connecting component, and at least one of the adjacent folding side plates is connected with the connecting component; and in the closed state, the connecting component can be detachably connected with another folding side plate.

[0057] That is to say, the adjacent folding side plates are connected by the connecting component between the mutually approaching ends, so that the plurality of folding side plates are sequentially connected end to end to form a closed structure. Obviously, the detachable connection between the adjacent folding side plates can be formed by the setting of the structure of the connecting component itself. Such a setting can facilitate the disassembly and assembly of the folding side plates, corresponding to quick packing and unpacking.

[0058] Exemplarily, the connecting component includes a first part and a second part, the first part and the second part are respectively arranged on the adjacent folding side plates, and the first part and the second part are detachably connected. Thus, in actual use, the connection and separation between the adjacent folding side plates can be realized by connecting and separating the first part and the second part.

[0059] More specifically, exemplarily, the first part can be a rotatable bolt, and the second part is a nut cooperating with the rotatable bolt. Of course, in other embodiments, the first part is a male buckle and the second part is a female buckle; or, a strong magic tape structure, etc. are adopted, which are not specifically limited herein.

[0060] As Figure 2 and Figure 4 shown, in some embodiments, one of the adjacent folding side plates has a groove portion, and the other of the adjacent folding side plates has a plug-in portion, and the plug-in portion can penetrate through the groove portion, and the plug-in portion and the groove portion constitute the connecting component.

[0061] In this embodiment, after folding multiple folding side plates together, one insertion part in the adjacent folding side plates is inserted into the groove part to achieve quick connection. Obviously, this result facilitates disassembly and assembly, and the connection and separation can be completed directly by plugging and unplugging.

[0062] Exemplarily, the insertion part has an insertion end that can be inserted into the groove part, and the part of the insertion end extending out of the groove part is bent to form a block, so as to prevent the insertion part from disengaging from the groove part during subsequent moving. Optionally, the insertion part is set as a cardboard structure and is easy to bend. Of course, the insertion part and the folding side plate can be integrally arranged.

[0063] Alternatively, in other embodiments, the widest dimension of the part of the insertion end of the insertion part extending out of the groove part is slightly larger than the maximum width of the groove part. Thus, through the cooperation of the two, the insertion end is not easily disengaged from the groove part.

[0064] Alternatively, in other embodiments, the insertion part has a large front width and a small rear width, and the front end is the end inserted into the groove part. Thus, the edge of the groove opening can be caught in the rear end by the front end shifting to play a blocking effect, etc., which will not be specifically limited here.

[0065] As Figure 2 、 Figure 4 and Figure 5 shown, in some embodiments, the groove part is foldably connected to the corresponding folding side plate; wherein, in the folded state, the groove part can be folded to a first preset position, and the first preset position is configured to enable the position of the insertion part to correspond to the position of the groove part, and enable at least part of the groove part to overlap with the folding side plate where the insertion part is located.

[0066] That is to say, by setting the groove part in a foldable form, the occupied space of the paper tray body in the unfolded state can be reduced. In addition, the folding action of the groove part can facilitate the control of sleeving the groove part on the insertion part or disengaging from the insertion part; in other words, it is convenient to control the insertion or extraction of the insertion part into or out of the groove part, which is convenient for assembling the paper tray body.

[0067] Exemplarily, when folding the groove part to make it close to the adjacent folding side plate provided with the insertion part, the insertion part fixed on the folding side plate can be close to and inserted into the groove part; when folding the groove part to make it away from the adjacent folding side plate provided with the insertion part, the insertion part fixed on the folding side plate can be away from and pulled out of the groove part.

[0068] It should be noted that the groove part has at least one fixed position during the folding process. At this fixed position, at least part of the groove part overlaps with the folding side plate where the insertion part is located. Obviously, by the groove part fitting with the folding side plate, the opening area of the groove part and the cross-sectional area of the insertion part can be increased, the connection strength between adjacent folding side plates can be increased, and it is convenient to hold the folding side plate to carry the product subsequently.

[0069] like Figure 4 As shown, in some embodiments, the groove portion at the first preset position is abutted against the bottom plate 100; and, in the folded state, adjacent folded side panels are abutted against each other.

[0070] That is, when the groove portion is folded to the first preset position, the groove portion is in contact with the bottom plate 100 and the adjacent folding side plate at the same time, thereby facilitating quick positioning of the groove portion. In other words, when the groove portion is folded, the groove portion is folded to abut against the bottom plate 100 and the adjacent folding side plate at the same time, which means that the groove portion is folded to the first preset position.

[0071] Exemplarily, the groove portion has a bottom end and side surfaces, the bottom end of the groove portion located at the first preset position abuts against the bottom plate 100 , and the side surfaces abut against the adjacent folding side plates.

[0072] like Figure 2 and Figure 6 As shown, in some embodiments, the plug-in portion is foldably connected to the corresponding folding side panel; wherein, in the folded state, the plug-in portion can be folded along a preset track, and the groove portion is located on the preset track.

[0073] That is to say, when all the foldable side panels are in a closed state, the groove portion is arranged on a preset track of the plug-in portion, and then the plug-in portion can be inserted into or out of the groove portion by folding and rotating the plug-in portion.

[0074] For example, the preset track is an arc track in a vertical plane, the groove is located on the arc track, and the plug-in part moves along the arc track in the vertical plane, and must pass through the groove, thereby controlling the plug-in part to be inserted into or out of the groove. Of course, in other embodiments, the preset track can also be an arc track in a horizontal plane.

[0075] like Figure 2 and Figure 6 As shown, in some embodiments, the plug-in portion is foldably connected to the corresponding folding side panel; wherein, in the closed state, the plug-in portion can be folded along a preset trajectory, and the groove portion at the first preset position is located on the preset trajectory.

[0076] That is to say, on the basis of the above-mentioned embodiment, by coordinating the folding action of the plug-in portion with the folding action of the groove portion, after the plug-in portion is inserted into the groove portion, the plug-in portion and the groove portion can be deformed and displaced to increase the friction between the two, thereby increasing the stability of the two.

[0077] In addition, the folding action of the plug-in portion is coordinated with the folding action of the groove portion, which is conducive to forming a clearance space, making it easier for the plug-in portion to be inserted into the groove portion.

[0078] Exemplarily, the preset trajectory is an arc trajectory in the vertical plane, the groove portion is located on the arc trajectory, the insertion portion moves along the arc trajectory in the vertical plane, and the groove portion is folded to the first preset position in the horizontal plane. Since the groove portion is located at the first preset position and the first preset position is located on the arc trajectory, the insertion portion will necessarily pass through the groove portion.

[0079] As Figure 2 and Figure 6 shown, in some embodiments, the groove portion includes a connecting plate 500, the connecting plate 500 is foldably connected to the corresponding folding side plate, and the connecting plate 500 is penetrated with a first slot 510;

[0080] The insertion portion includes a first insertion plate 330, the first insertion plate 330 is foldably connected to the corresponding folding side plate, and the first insertion plate 330 can be inserted into the corresponding first slot 510.

[0081] Exemplarily, the connecting plate 500 and the corresponding folding side plate are integrally provided, both are made of cardboard, and a crease line is provided between the connecting plate 500 and the corresponding folding side plate so that the connecting plate 500 can be folded and rotated relative to the folding side plate. Among them, the first slot 510 is formed by opening a hole groove in the connecting plate 500.

[0082] Similarly, the first insertion plate 330 and the corresponding folding side plate are integrally provided, both are made of cardboard, and a crease line is provided between the first insertion plate 330 and the folding side plate so that the first insertion plate 330 can be folded and rotated relative to the folding side plate.

[0083] Exemplarily, in order to further improve the connection strength between adjacent folding side plates, the first slot 510 extends in a direction parallel to the bottom plate 100, and the first insertion plate 330 is also arranged to extend in a direction parallel to the bottom plate 100, so as to increase the contact area between the first slot 510 and the first insertion plate 330, increase the friction between the two, and achieve the function of anti-disengagement.

[0084] As Figure 2 and Figure 4 shown, in some embodiments, the connecting plate 500 has a clamping end 520, and the folding side plate where the insertion portion is located and / or the bottom plate 100 has a clamping groove 430; in the closed state, the clamping end 520 can be clamped with the clamping groove 430.

[0085] That is to say, there are the following situations:

[0086] Situation 1: The connecting plate 500 has a pair of clamping ends 520, and the folding side plate and the bottom plate 100 are both provided with clamping grooves 430. By respectively clamping the pair of clamping ends 520 into the clamping groove 430 on the folding side plate and the clamping groove 430 on the bottom plate 100;

[0087] Case 2: The connecting plate 500 has a snap-in end 520, and only the folding side plate has a snap-in slot 430, and the snap-in end 520 is snapped into the snap-in slot 430 on the folding side plate;

[0088] Case 3: the connecting plate 500 has a clamping end 520 , and only the bottom plate 100 has a clamping slot 430 , and the clamping end 520 is clamped into the clamping slot 430 on the bottom plate 100 .

[0089] Obviously, the above methods are all for limiting the connection board 500 to prevent the connection board 500 from shifting and causing the first plug board 330 to be separated from the first slot 510. It should be noted that the limiting direction of the card slot 430 on the card end 520 and the direction of the first plug board 330 inserting into the first slot 510 are perpendicular to each other.

[0090] like Figure 4 As shown, in some embodiments, the folding side panels include a plurality of first folding side panels 300 and a plurality of second folding side panels 200, and the second folding side panels 200 are respectively provided at both ends of the first folding side panels 300, and the first folding side panels 300 are respectively provided at both ends of the second folding side panels 200; wherein, the first folding side panels 300 are respectively provided with plug-in portions at both ends, and the second folding side panels 200 are respectively provided with groove portions at both ends.

[0091] That is to say, when the plug-in portion and the groove portion are both located on the inner side of the first folding side panel 300, the plug-in portion can be driven to separate from the groove portion by bending the first folding side panel 300 toward the outer side of the first folding side panel 300, thereby realizing the unfolding of the paper tray body; when the plug-in portion and the groove portion are both located on the outer side of the first folding side panel 300, the plug-in portion can be driven to separate from the groove portion by bending the first folding side panel 300 toward the inner side of the first folding side panel 300, thereby realizing the unfolding of the paper tray body.

[0092] It should be noted that the plug-in portion and the groove portion are arranged on the inner side of the first folding side panel 300, so that the unfolding operation is more convenient and the inner space of the paper tray can be saved. In other words, when the gap between the inner side of the folding side panel and the product is very small, it is difficult to drive the plug-in portion out of the groove portion by bending the first folding side panel 300 toward the inner side.

[0093] like Figure 3 and Figure 4 As shown, in some embodiments, the first folding side panel 300 is foldably connected to the handle panel 400, and the handle panel 400 can be folded to a second preset position to form a slot 430 between the handle panel 400 and the first folding side panel 300; one of the first folding side panel 300 and the handle panel 400 is provided with a second slot 320, and the other is provided with a second plug-in plate 420, and the second plug-in plate 420 can be inserted into the second slot 320.

[0094] In this embodiment, the handle plate 400 forms a handle after being folded. By arranging the handle plate 400 on the first folding side plate 300, it is convenient for manual handling of the products loaded into the paper tray. That is to say, multiple people can cooperate to respectively grasp the handle, which is convenient for movement.

[0095] Exemplarily, the second preset position is arranged on one side of the first folding side plate 300. When the handle plate 400 moves to the second preset position, the handle plate 400 is parallel to the first folding side plate 300. Of course, the second preset position needs to be on the same side as the connecting plate 500. For example, both the second preset position and the connecting plate 500 are located inside the first folding side plate 300. Correspondingly, the first insertion plate 330 is also located or faces the inside of the first folding side plate 300 to ensure that the first insertion plate 330 can be inserted into the first slot 510 on the connecting plate 500; or, both the second preset position and the connecting plate 500 are located outside the first folding side plate 300. Correspondingly, the first insertion plate 330 is also located or faces the outside of the first folding side plate 300 to ensure that the first insertion plate 330 can be inserted into the first slot 510 on the connecting plate 500.

[0096] In addition, since the handle plate 400 is folded to be parallel to the first folding side plate 300, and the position of the handle plate 400 is defined by the cooperation of the second slot 320 and the second insertion plate 420, so that the gap between the handle plate 400 and the first folding side plate 300 forms the above-mentioned card slot 430. Furthermore, by rotating the connecting plate 500, the clamping end 520 on the connecting plate 500 can be driven to approach and be clamped into the card slot 430. The card slot 430 cooperates with the clamping end 520 to limit the connecting plate 500 from approaching or moving away from the first folding side plate 300, so that the first insertion plate 330 can be stably inserted into the first slot 510 of the connecting plate 500. That is to say, the first folding side plate 300 and the second folding side plate 200 can be stably connected.

[0097] It should be noted that the handle plate 400 can be lifted obliquely alone to increase the gap between the handle plate 400 and the first folding side plate 300, so as to release the limit of the card slot 430 on the clamping end 520 and facilitate the disassembly of the first folding side plate 300 and the connecting plate 500.

[0098] Similarly, after the limit of the card slot 430 on the clamping end 520 is released, the first folding side plate 300 is moved away from the connecting plate 500, and then the first insertion plate 330 can be automatically pulled out of the first slot 510, completing the rapid separation of the first folding side plate 300 and the second folding side plate 200, and making the paper tray body in an unfolded state, which is convenient for taking out the product.

[0099] Of course, the first plug board 330 and the connecting plate 500 are both made of cardboard, which has the ability to deform and rigidly move, and can meet the connection strength requirements between the first plug board 330 and the first slot 510, and the card slot 430 and the card end 520, and the deformation requirements when the first plug board 330 and the card end 520 are pulled out.

[0100] For example, the paperboard is made of paper pulp, corrugated paperboard, honeycomb paperboard and other paper materials as the main raw materials. In other words, there are many types of paperboard, which are not specifically limited here.

[0101] For example, the connecting plate 500 , the second folding side plate 200 and the clamping end 520 are integrated, for example, made of cardboard. The clamping end 520 and the first slot 510 are formed by cutting on the connecting plate 500 .

[0102] Of course, the first folding side panel 300 and the first plugging plate 330 are integrated and can also be made of cardboard. The first plugging plate 330 is formed by cutting on the first folding side panel 300.

[0103] For example, in this embodiment, the handle plate 400 can be folded and connected to the upper end of the first folding side plate 300, and the corresponding card slot 430 is located at the upper end of the card connection end 520. Then, the user can achieve the separation between the card slot 430 and the card connection end 520 by tilting the handle plate 400 or the first folding side plate 300. Of course, the height of the handle plate 400 after folding can be set higher than the second folding side plate 200, so as to distinguish the first folding side plate 300 from the second folding side plate 200, and to reduce the degree of bending when the staff holds the handle plate 400.

[0104] like Figure 7 and Figure 8 As shown, in some embodiments, the first foldable side panel 300 has a first handle hole 310, the handle panel 400 has a second handle hole 410, and the second handle hole 410 of the handle panel 400 at the second preset position is connected to the first handle hole 310; wherein the first foldable side panel 300 is located on the outside of the groove.

[0105] That is to say, when the handle panel 400 is folded to be parallel to the first folding side panel 300, the first handle hole 310 and the second handle hole 410 are connected to form a channel for the user's hand to insert and hold, so that the hand can hold the first folding side panel 300 and the handle panel 400 more stably.

[0106] At the same time, the stability of the clamping between the clamping slot 430 and the clamping end 520 can be maintained by holding the first handle hole 310 and the second handle hole 410 at the same time. In other words, the clamping end 520 can be stably clamped by the handle plate 400 and the first folding side plate 300. When unpacking, the width of the clamping slot 430 can be increased by holding and bending only the first handle hole 310 or the second handle hole 410, so that the clamping end 520 can automatically detach from the clamping slot 430.

[0107] Exemplarily, the handle panel 400 is folded to the inner side of the first folding side panel 300, the connecting plate 500 is located on the inner side of the first folding side panel 300, and the first plug plate 330 is arranged on the inner side of the first folding side panel 300, so that the first handle hole 310 can be pulled obliquely to make the card end 520 disengage from the card slot 430, and the first plug plate 330 can be pulled out of the first slot 510, thereby completing the separation between the first folding side panel 300 and the second folding side panel 200.

[0108] For example, Figure 7 As shown, the number of the first folding side panels 300 is a pair, the number of the second folding side panels 200 is a pair, a pair of first folding side panels 300 are relatively arranged, and a pair of second folding side panels 200 are relatively arranged, so that the paper tray body can be quickly unfolded by swinging the pair of first folding side panels 300 outward at the same time.

[0109] like Figure 1 As shown, in the above embodiment, the bottom plate 100 and the folding side plate are integrated, and a crease line is provided between the bottom plate 100 and the folding side plate so that the folding side plate can be folded relative to the bottom plate 100 .

[0110] The connecting plate 500 and the second folding side plate 200 are integrally arranged, and a crease line is arranged between the connecting plate 500 and the second folding side plate 200 so that the connecting plate 500 can be folded relative to the second folding side plate 200 .

[0111] The first plug board 330 and the first folding side panel 300 are integrated, and a crease line is provided between the first plug board 330 and the first folding side panel 300, so that the first plug board 330 can be folded relative to the first folding side panel 300. Optionally, the first plug board 330 has an insertion end, and a crease line is provided between the insertion end and the plug board, so as to ensure that the insertion end can be bent after being inserted through the first slot 510, thereby preventing the first plug board 330 from being separated from the first slot 510. It should be noted that, since the rigidity of the paperboard is relatively low, the first plug board 330 can be driven to be separated from the first slot 510 when the first folding side panel 300 is bent.

[0112] The handle plate 400 and the first folding side plate 300 are integrally arranged, and a crease line is provided between the handle plate 400 and the first folding side plate 300 so that the handle plate 400 can be folded relative to the first folding side plate 300.

[0113] In addition, for the convenience of understanding, as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the steps for closing the paper tray are as follows:

[0114] Step 1: Fold the handle plate 400 and insert the second plug plate 420 into the second slot 320 to complete the fixation of the first folding side plate 300 and the handle plate 400;

[0115] Step 2: Fold the second folding side plate 200 and the connecting plate 500 so that the connecting plate 500 is in the first preset position;

[0116] Step 3: Fold the first folding side plate 300 to close it with the second folding side plate 200, and insert the first plug plate 330 into the first slot 510 to complete the closing and fixation of the paper tray body.

[0117] And, as Figure 7 and Figure 8 shown, the steps for unfolding the paper tray are as follows:

[0118] Step 1: Lift the first folding side plate 300 obliquely to pull out the first plug plate 330 from the first slot 510, so that the first folding side plate 300 and the second folding side plate 200 are separated;

[0119] Step 2: Rotate the first folding side plate 300 and the second folding side plate 200 to be flush with the bottom plate 100 to complete the unfolding of the paper tray body.
