[0036] 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.

[0037] In existing technologies, automated storage and retrieval systems (AS / RS) robots need to have a low-profile, thin structure to adapt to dense storage environments, while also accommodating a variety of mechanical and electrical components. Traditional chassis are manufactured using welding processes, which can lead to insufficient dimensional accuracy due to welding deformation. The complex welding process increases manufacturing costs, and stress concentration areas are prone to cracking, affecting structural reliability.

[0038] How to achieve high-precision assembly of the chassis without relying on welding? Explore ways to reduce processing difficulty through modular design and reduce stress concentration by using detachable connection methods.

[0039] Therefore, this utility model provides a vehicle frame, such as Figure 1-4 As shown, the frame includes an outer frame plate and an inner plate. The outer frame plate is a rectangular structure formed by splicing multiple pieces end to end. Adjacent outer frame plates are connected by mortise and tenon joints. The inner plate is set inside the rectangular structure and is arranged parallel to the outer frame plate at intervals. The ends of the inner plate are connected to the outer frame plate by mortise and tenon joints.

[0040] Mortise and tenon joints achieve positioning and fixing between boards by interlocking protrusions and grooves. Specifically, dovetail or right-angle tenon structures can be used to avoid welding deformation and improve assembly accuracy.

[0041] Specifically, the outer frame panels are joined together with mortise and tenon joints at both ends to form a closed rectangular frame, ensuring the overall structural stability. The inner panels are installed parallel to the inner side of the outer frame panels, with a gap maintained between them for the placement of electrical components. The two ends of the inner panels are embedded into the tenon grooves H of the outer frame panels for fixation.

[0042] Through the above technical solutions, this utility model achieves weld-free assembly of the chassis, improving dimensional accuracy and structural consistency. The parallel layout of the inner plates enhances the rigidity of the frame, and the mortise and tenon joints disperse stress concentration, extending the service life of the chassis. The modular design allows for adjustment of the number of inner plates according to load-bearing requirements, adapting to the layout of robots of different specifications.

[0043] To strengthen the connection of mortise and tenon joints, such as Figure 1-4As shown, screw holes are provided between the ends of adjacent outer frame panels or inner panels and the outer frame panel. The screw holes are used to install screws to strengthen the connection.

[0044] Screw holes are through holes added to the mortise and tenon joint structure to accommodate screws and provide mechanical fastening. The outer frame and inner panels of the mortise and tenon joint have through screw holes at the joint. When a screw is screwed in, its thread creates frictional resistance against the hole wall, while its head presses against the joint surface. This dual constraint mechanism counteracts the lateral shear force experienced by the frame during handling operations, especially under frequent start-stop conditions, preventing gaps from forming at the mortise and tenon joint due to vibration. The screw holes can be located in or near the overlapping area of ​​the tenon E and the mortise H, for example, multiple holes spaced apart near the tenon E to form multi-point locking.

[0045] As a preferred embodiment, such as Figure 1-3 As shown, the outer frame panel includes four pieces, namely the left outer frame 11, the right outer frame 12, the front outer frame 13 and the rear outer frame 14. The left outer frame 11, the right outer frame 12, the front outer frame 13 and the rear outer frame 14 are connected end to end with mortise and tenon joints.

[0046] The left outer frame 11, right outer frame 12, front outer frame 13 and rear outer frame 14 are provided with corresponding mounting holes, clearance holes and screw holes to facilitate the installation and fixing of electrical components.

[0047] The left outer frame 11 and right outer frame 12 are arranged parallel to each other, while the front outer frame 13 and rear outer frame 14 are arranged perpendicular to the left outer frame 11 and right outer frame 12, respectively. The four outer frames are connected end-to-end with mortise and tenon joints to form a rectangular frame structure. The two ends of the left outer frame 11 are connected to one end of the front outer frame 13 and the rear outer frame 14, respectively, and the two ends of the right outer frame 12 are connected to the other ends of the front outer frame 13 and the rear outer frame 14, respectively. The mortise and tenon joints create a stable right-angle butt joint between the outer frame panels, allowing for frame assembly without welding.

[0048] In detail, the two ends of the left outer frame 11 and the two ends of the right outer frame 12 are provided with mortise grooves H, and the two ends of the front outer frame 13 and the two ends of the rear outer frame 14 are provided with tenons E that are adapted to the mortise grooves H.

[0049] The tenon H is a groove structure formed at the ends of the left outer frame 11 and the right outer frame 12. It can be implemented using a rectangular or trapezoidal cross-section groove; in this embodiment, a rectangular groove is preferred. It is used to accommodate the tenon E and restrict relative displacement. The tenon E is a protrusion structure provided at the ends of the front outer frame 13 and the rear outer frame 14. It can be implemented using a rectangular or trapezoidal protrusion that matches the shape of the tenon H; in this embodiment, a rectangular protrusion is preferred. It is used to insert into the tenon H to form a fitting connection. The fit between the tenon H and the tenon E is controlled by dimensional tolerances, ensuring a tight fit between the outer frame panels.

[0050] In this embodiment, the left outer frame 11 and right outer frame 12 serve as longitudinal support structures on both sides of the frame. Their ends are connected to the tenons E of the front outer frame 13 and rear outer frame 14 via mortise and tenon joints H. The way the mortise and tenon joints H and E are engaged eliminates the need for welding when assembling the outer frame panels; positioning and fixing are achieved simply by pushing the tenon E along the direction of the mortise and tenon joints H. This connection method avoids welding deformation and enhances the connection strength through the self-locking characteristics of the mortise and tenon structure.

[0051] As a preferred embodiment, such as Figure 1-4 As shown, the inner panel includes a front inner panel 23 and a rear inner panel 24. Both ends of the front inner panel 23 and both ends of the rear inner panel 24 are provided with tenons E. The left outer frame 11 and the right outer frame 12 are provided with mortises F that are adapted to the tenons E.

[0052] The front inner panel 23 and the rear inner panel 24 are provided with corresponding mounting holes, clearance holes and screw holes to facilitate the installation and fixing of electrical components.

[0053] The front inner panel 23 and the rear inner panel 24 are inserted into the mortise holes F of the left outer frame 11 and the right outer frame 12 respectively through tenons E at their ends, forming a connection structure perpendicular to the left or right frame panel. The clearance fit between the tenon E and the mortise hole F can eliminate assembly errors and limit the relative displacement between the inner panel and the outer frame panel.

[0054] like Figure 1 , Figure 2 and Figure 4 As shown, both the front inner plate 23 and the rear inner plate 24 are provided with lifting mounting holes 231 for mounting the lifting and reversing actuator 52. The lifting mounting holes 231 are through holes penetrating the front inner plate 23 and the rear inner plate 24, used to fix the lifting and reversing actuator 52. The lifting mounting holes 231 are symmetrically distributed along the length of the front inner plate 23 and the rear inner plate 24, and their positions correspond to the mounting base of the lifting and reversing actuator 52, so that the center of gravity of the actuator is located in the central area of ​​the front inner plate 23 and the rear inner plate 24.

[0055] As a preferred embodiment, in order to strengthen the connection strength between the outer frame panels and the inner panels, such as Figure 1 and Figure 2 As shown, a block-shaped reinforcing plate 3 can be detachably provided between the front outer frame 13 and the front inner panel 23. The block-shaped reinforcing plates 3 are arranged in pairs and located on opposite sides of the front outer frame 13 and the front inner panel 23.

[0056] Alternatively, a block-shaped reinforcing plate 3 may be detachably provided between the rear outer frame 14 and the rear inner panel 24. The block-shaped reinforcing plates 3 are provided in pairs and located on opposite sides of the rear outer frame 14 and the rear inner panel 24.

[0057] The block-shaped reinforcing plate 3 is a rigid plate with a regular geometric shape. It can be made by stamping metal or composite materials. It is used to increase the connection strength at the front and rear ends of the frame while forming a local support structure.

[0058] Specifically, the block-shaped reinforcing plate 3 is installed between the front outer frame 13 and the front inner plate 23 or between the rear outer frame 14 and the rear inner plate 24 through a detachable connection, and the paired reinforcing plates form a clamping structure on both sides.

[0059] In addition, such as Figure 2 and Figure 3 As shown, the corners of the front inner panel 23 with the left outer frame 11 and the right outer frame 12 are detachably provided with corner reinforcing plates 4, or the corners of the rear inner panel 24 with the left outer frame 11 and the right outer frame 12 are detachably provided with corner reinforcing plates 4.

[0060] The corner reinforcement plate 4 refers to a plate-like structure with a right-angle shape, whose shape complements the corner area to disperse stress.

[0061] Specifically, at the right-angle intersection of the left outer frame 11, right outer frame 12, and front inner panel 23 or rear inner panel 24, an angled reinforcing plate 4 is installed to cover the corner area. The two edges of the angled reinforcing plate 4 are respectively attached to the side walls of the left outer frame 11 and right outer frame 12, and simultaneously attached to the end of the front inner panel 23 or rear inner panel 24, and then fixed with screws. When the frame bears a load, the angled reinforcing plate 4 transfers the load to the connection area between the outer frame and the inner panel through the contact surface, thereby reducing stress concentration at the corner. The angled reinforcing plate 4 adopts a split installation method, allowing for replacement or reinforcement without damaging the main structure.

[0062] In a preferred embodiment, a guide mechanism is provided between the front outer frame 13 and the front inner plate 23, and a guide mechanism is also provided between the rear outer frame 14 and the rear inner plate 24. The guide mechanism is used to guide the lifting and reversing actuator.

[0063] In a preferred embodiment, an inner middle plate is provided between the left outer frame 11 and the right outer frame 12, and both ends of the inner middle plate are mortised and tenoned to the left outer frame 11 and the right outer frame 12.

[0064] It should be noted that when an inner middle plate is present, the left inner plate 21 and the right inner plate 22 are not required.

[0065] The inner middle plate is a longitudinal support plate set between the left outer frame 11 and the right outer frame 12. It is used to form an auxiliary load-bearing structure in the middle of the frame and can fix the walking gearbox of the walking drive mechanism 61.

[0066] In a preferred embodiment, the inner panel also includes a left inner panel 21 and a right inner panel 22. The left inner panel 21 and the right inner panel 22 are spaced apart by a predetermined distance and are arranged parallel to each other between the front inner panel 23 and the rear inner panel 24. Both ends of the left inner panel 21 and both ends of the right inner panel 22 are mortised and tenoned to the front inner panel 23 and the rear inner panel 24.

[0067] The left inner plate 21 and the right inner plate 22 are provided with corresponding mounting holes, clearance holes and screw holes to facilitate the installation and fixing of electrical components.

[0068] It should be noted that this implementation does not have an inner plate.

[0069] The left inner panel 21 is the left side panel located between the front inner panel 23 and the rear inner panel 24, and the right inner panel 22 is the right side panel located between the front inner panel 23 and the rear inner panel 24. The preset spacing refers to maintaining a fixed distance between the left inner panel 21 and the right inner panel 22, which can be achieved by adjusting the position of the tenon and mortise connection. This is used to form a stable support network in a limited space and avoid structural redundancy.

[0070] Specifically, the left inner panel 21 and the right inner panel 22 are arranged parallel to each other between the front inner panel 23 and the rear inner panel 24, and their ends are embedded into the corresponding connection positions of the front inner panel 23 and the rear inner panel 24 through mortise and tenon structures. This layout forms a grid-like structure inside the frame, distributing the load through multi-directional force distribution while maintaining the overall low thickness of the frame. During assembly, the mortise and tenon connections of the left inner panel 21, the right inner panel 22, the front inner panel 23, and the rear inner panel 24 can achieve rapid positioning, avoiding deformation problems caused by welding.

[0071] Screw holes are provided at the mortise and tenon joints for further reinforcement with screws.

[0072] This utility model also provides a three-dimensional warehousing robot, such as Figure 5 As shown, it includes a frame, a walking drive mechanism 61, a lifting and reversing drive mechanism 51, a battery, and electrical components. The walking drive mechanism 61 and the lifting and reversing drive mechanism 51 are mounted on the inner panel, and the battery and electrical components are mounted in the internal area of ​​the inner panel assembly.

[0073] The area where the inner panel is assembled mainly includes the walking drive mechanism 61, the lifting and reversing drive mechanism 51, and the installation area for the battery and electrical equipment. The walking drive mechanism 61 is installed and fixed on the left inner panel 21 or the right inner panel 22, while the lifting and reversing drive mechanism 51 is installed and fixed on the front inner panel 23 and the rear inner panel 24. The battery and the main electrical components are located in the internal area of ​​the inner panel assembly.

[0074] The area formed between the front inner plate 23 and the rear inner plate 24 and the front outer frame 13 and the rear outer frame 14 is the working area of ​​the lifting and reversing actuator 52. The area between the left inner plate 21 and the right inner plate 22 and the left outer frame 11 and the right outer frame 12 is the installation area of ​​the traveling actuator (including the main rail traveling actuator 62 and the sub-rail traveling actuator 63).

[0075] The outer sides of the left outer frame 11 and the right outer frame 12 are equipped with sub-rail traveling wheels via bearing seats, while the main rail traveling wheels are installed on the lifting and reversing actuator 52.

[0076] Furthermore, a guide mechanism for the lifting and reversing actuator 52 is provided between the front inner panel 23 and the rear inner panel 24 and the front outer frame 13 and the rear outer frame 14.
