Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics technology, and in particular to sheet metal, chassis and automated warehousing robots. Background Technology

[0002] In automated warehousing, to save manpower and improve work efficiency, automated storage and retrieval systems (AS / RS) are typically used to move goods. AS / RS robots are logistics devices that perform four-way planar transport of pallets within an automated warehouse. Their operation is achieved through the coordinated function of two independent transmission mechanisms: a lifting transmission mechanism and a walking transmission mechanism. They are also equipped with batteries, electrical equipment, sensors, and other components. Currently, warehousing often requires dense storage, necessitating that AS / RS robots be able to accommodate various mechanical and electrical components while maintaining a sufficiently low and thin profile in the vertical direction, and also possess high structural strength.

[0003] Automated storage robots (four-way vehicles) generally use a frame-plate type chassis. The frame plates are machined and, depending on the functional requirements, have tenons, mortises, screw holes for connecting with other frame plates, mounting holes for connecting with other components, and corresponding wire passage holes and clearance holes.

[0004] To achieve sufficient strength, thicker and longer plates are usually selected for the frame panels. Machining the entire plate makes the processing cost very high. In addition, using a frame panel for the whole frame increases the weight of the vehicle and makes it inconvenient for assembly, on-site implementation and maintenance. Utility Model Content

[0005] In view of this, one of the objectives of this utility model is to provide a plate component to solve the technical problems in the prior art, such as the use of thicker and longer plates for the frame plate, the machining of the entire plate, which results in high processing costs, and the use of the frame plate as the whole frame, which increases the weight of the vehicle body and makes it inconvenient for assembly, on-site implementation and maintenance.

[0006] The second objective of this utility model is to provide a vehicle frame containing plates.

[0007] The third objective of this utility model is to provide a three-dimensional warehouse robot with a frame.

[0008] To achieve one of the above objectives, this utility model provides a plate component, including a machined plate component and a sheet metal plate component, wherein the machined plate component and the sheet metal plate component are stacked together, the machined plate component is provided with tenons, mortises, screw holes and mounting holes, and the sheet metal plate component is provided with tenons, mortises, screw holes and mounting holes at corresponding positions.

[0009] Optionally, the tenon, the mortise, the screw hole, and the mounting hole on the machined plate serve as the main mounting positions.

[0010] Optionally, the tenon, the mortise, the screw hole, and the mounting hole on the sheet metal part serve as secondary mounting positions.

[0011] Optionally, when the mounting position is in an internal fitting configuration, the size of the secondary mounting position is larger than the size of the primary mounting position.

[0012] Optionally, in the case of an external mounting configuration, the size of the secondary mounting position is smaller than the size of the primary mounting position.

[0013] Optionally, both the machined sheet and the sheet metal sheet are provided with screw holes, and the screw holes are used to install screws for connecting the machined sheet and the sheet metal sheet.

[0014] Optionally, the sheet metal part has bends, pleats, or reinforcing ribs at at least some locations.

[0015] Optionally, the bend is located at the edge of the sheet metal part.

[0016] To achieve the second objective mentioned above, this utility model provides a vehicle frame, comprising several plates as described above, wherein the plates are joined end to end to form a rectangular structure, and adjacent plates are connected by mortise and tenon joints.

[0017] To achieve the third objective mentioned above, this utility model provides a three-dimensional warehousing robot, including the aforementioned chassis.

[0018] The plate component provided by this utility model has the following technical effects:

[0019] This type of panel mainly consists of machined panels and sheet metal panels, which are stacked together. The machined panels have tenons, mortises, screw holes, and mounting holes, while the sheet metal panels have corresponding tenons, mortises, screw holes, and mounting holes. This composite structure, through interlayer stress dispersion, exhibits higher deformation resistance than a single sheet metal of the same thickness, while effectively reducing material consumption and processing costs while ensuring the structural strength of the vehicle frame. The stacked structure of the panels reduces the overall weight, facilitating on-site assembly and maintenance. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In existing technologies, thick plates are often used to ensure structural strength, resulting in high material consumption, long processing cycles, and high manufacturing costs. Thick plate structures also increase the overall weight of the frame, leading to inconvenience in operation and difficulties in maintenance when assembling in confined spaces. For example, in densely populated warehouse scenarios, the frame needs to integrate transmission mechanisms and electrical components within a limited height, making it difficult for a single machined sheet metal part to simultaneously meet the requirements of lightweight design and high strength.

[0031] To address the aforementioned issues, researchers noted that while machined sheet metal (part 1) offered high precision, it was also expensive, while sheet metal components offered lightweight advantages but suffered from insufficient localized strength. This led to the idea of ​​combining the two processes: using machined sheet metal (part 1) to support critical connection areas, and sheet metal (part 2) as an auxiliary support layer. Further research revealed that stacking the two types of sheets retained the capability for precision hole machining while simultaneously reinforcing weak areas with the sheet metal. By optimizing the hole correspondence between the sheets, a collaborative load-bearing structure could be achieved.

[0032] Therefore, this utility model provides a plate component, such as... Figure 1-6 As shown, this type of panel includes a machined panel 1 and a sheet metal panel 2, which are composite and stacked. The machined panel 1 is provided with tenons 3, mortises 6, screw holes 4 and mounting holes 5, and the sheet metal panel 2 is provided with the same type of holes at corresponding positions.

[0033] Machined sheet 1 is a metal sheet formed through milling and drilling processes, specifically made of aluminum alloy or steel sheet, used to bear the main assembly stress. Sheet metal sheet 2 is a thin metal sheet formed through stamping and bending processes, specifically made of cold-rolled steel sheet or galvanized sheet, used to expand the structural support area. Composite stacking refers to the combination of two sheets by planar bonding, specifically fixed by adhesive or bolt connection, forming a multi-layer composite structure. In this embodiment, bolt connection is preferred.

[0034] Specifically, machined sheet 1 serves as the main load-bearing layer, with its high-precision holes ensuring accurate assembly of the transmission mechanism and electrical components. Sheet metal sheet 2 serves as an auxiliary layer, enhancing overall bending stiffness through its large-area coverage. After the two sheets are stacked, the tenon 3 of machined sheet 1 coincides with the tenon 3 of sheet metal sheet 2.

[0035] This novel composite structure, through interlayer stress dispersion, exhibits higher deformation resistance than a single sheet metal of the same thickness, while simultaneously reducing material consumption and processing costs while ensuring the structural strength of the vehicle frame. The layered structure of the sheet metal reduces overall weight, facilitating on-site assembly and maintenance. The synergistic effect of the two sheet metal components meets the requirements of precision assembly, adapting to the dual demands of compact space and high load-bearing capacity for automated storage and retrieval systems (AS / RS).

[0036] Detailed, such as Figure 1 and Figure 2 As shown, the tenon 3, mortise 6, screw hole 4, and mounting hole 5 on the machined sheet metal part 1 serve as primary mounting positions. The tenon 3, mortise 6, screw hole 4, and mounting hole 5 on the sheet metal part 2 serve as secondary mounting positions.

[0037] The secondary mounting position is theoretically designed not to have a limiting contact with the frame plate or components to be connected, because the sheet metal part 2 is generally made by laser cutting, and the dimensional control accuracy is much lower than that of machining.

[0038] The tenon 3 is a raised structure formed on the edge of the board, used to form a mating fit with the tenon 6 of the adjacent board. The tenon 6 is a recessed or hole-like structure formed on the surface of the board, used to accommodate the tenon 3 of the adjacent board to achieve a positioning connection.

[0039] The aforementioned primary mounting positions refer to the areas on the machined sheet metal 1 used for supporting core connections and installation functions. By concentrating the tenons 3, mortises 6, screw holes 4, and mounting holes 5 in this area, the reliance on the machining of the sheet metal 2 can be reduced. Secondary mounting positions are structural locations used to assist in fixing or bearing non-critical loads. Specifically, they can be achieved by forming holes or protrusions on the sheet metal 2 using stamping or laser cutting processes. Their function is to distribute the stress distribution in the primary load-bearing area and reduce the local load on the machined sheet metal 1.

[0040] During assembly, adjacent panels are quickly positioned using mortise and tenon joints. Screw holes 4 are used to fix external components, while mounting holes 5 are used to install sensors or transmission components. Since the machined panel 1 undertakes the main mounting function, the sheet metal panel 2 only needs to have auxiliary mounting structures in secondary positions, thereby reducing the overall machining complexity.

[0041] During the load-bearing process, the secondary mounting position shares part of the mechanical load. For example, in a vibration environment, the sheet metal part 2 absorbs energy through elastic deformation, thereby reducing the fatigue risk of the machined sheet metal part 1.

[0042] In a preferred embodiment, when the mounting position is an internal fitting type, the size of the secondary mounting position is larger than the size of the primary mounting position.

[0043] Specifically, when a suitable internal fit is required, the secondary mounting hole diameter or groove width of the sheet metal part 2 is designed to be slightly larger than the corresponding size of the primary mounting position of the machined sheet metal part 1. For example, the diameter of the screw hole 4 of the sheet metal part 2 can be 0.5 mm to 1 mm larger than the diameter of the screw hole 4 of the machined sheet metal part 1, allowing for slight displacement of the sheet metal part 2 relative to the machined sheet metal part 1 during assembly, thereby reducing the requirements for machining accuracy. This design provides adjustment margin through the secondary mounting position of the sheet metal part 2, while the primary mounting position of the machined sheet metal part 1 can still maintain a precise positioning reference, ultimately achieving rapid assembly and structural stability of the sheet metal parts.

[0044] In a preferred embodiment, when the mounting position is an external mating type, the size of the secondary mounting position is smaller than the size of the primary mounting position.

[0045] When the mounting position is an external mating type, the secondary mounting position on the sheet metal part 2 is reduced in size to form a tight fit with the mating part.

[0046] As a preferred embodiment, such as Figure 1-6 As shown, both the machined sheet 1 and the sheet metal sheet 2 are provided with screw holes, and screws are installed in the screw holes to connect the machined sheet 1 and the sheet metal sheet 2.

[0047] Machined sheet 1 and sheet metal sheet 2 are stacked together using screw holes and screws. Screw holes are machined into machined sheet 1, and corresponding screw holes are punched or drilled into sheet metal sheet 2. Screws are passed through these screw holes and tightened to fix the two sheets of different materials into a single unit. During assembly, the screw connection allows for adjustment of the relative positions between the sheets, avoiding assembly difficulties caused by machining errors.

[0048] Compared to existing technologies, current frame panels are typically connected by integral machining or welding, resulting in high material costs and the inability to disassemble and maintain them. However, using separate screw holes and bolt connections reduces the thickness requirement of the machined plate 1, decreases material consumption, and facilitates disassembly, inspection, or replacement of damaged parts.

[0049] As a preferred embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, at least some parts of the sheet metal part 2 are provided with bends, folds or reinforcing ribs.

[0050] During the processing, the sheet metal part 2 forms an edge bending structure through a bending process. The bending is preferably located at the edge of the sheet metal part 2, facing one side of the sheet metal part 2. The sheet metal part 2 cannot guarantee strict dimensional accuracy.

[0051] Parallel folds are pressed in the middle area of ​​the sheet metal part 2 to disperse load stress through the corrugated structure; U-shaped reinforcing ribs are stamped around the connecting holes to prevent local collapse when under installation stress.

[0052] Sheet metal part 2 compensates for the strength loss caused by the thinning of the sheet metal through the above-mentioned structural features, while retaining the advantages of low sheet metal processing cost and high forming efficiency.

[0053] This embodiment also provides a vehicle frame, such as Figure 6 As shown, it includes several panels, which are spliced ​​together end to end to form a rectangular structure, and adjacent panels are connected by mortise and tenon joints.

[0054] The combination of machined sheet metal part 1 and sheet metal part 2 reduces the overall weight while ensuring structural strength. Multiple sheet metal parts are joined together end to end with mortise and tenon joints to form the main body of the rectangular frame. The mortise and tenon joints allow for quick positioning and fixation without the need for additional fasteners.

[0055] This embodiment also provides a three-dimensional warehousing robot, including the aforementioned frame, which is a rectangular structure formed by splicing several plates end to end, with adjacent plates connected by mortise and tenon joints.
