Description

Technical Field

[0001] The present application relates to the technical field of logistics handling equipment, and in particular to an electric multifunctional handling platform. Background Art

[0002] Electric handling platforms are used to achieve efficient and convenient material handling and are widely used in industrial production, warehousing and logistics, and other scenarios. Electric handling platforms are usually supported by a vehicle body, which is powered by a built-in battery pack. A drive system consisting of an electric motor, a reducer, and drive wheels is provided to enable the electric handling platform to travel and turn. The electric handling platform is equipped with a cargo carrying platform for placing cargo. The carrying platform has different shapes, sizes, and surface materials depending on the needs. Some platforms are equipped with lifting devices, such as scissors-type, chain-type, or hydraulic types, to achieve the lifting and lowering of cargo. The operating control part includes an operating handle and a control panel, which makes it convenient for the operator to control the platform's movements and understand the working status. In addition, the platform is also equipped with safety protection devices, such as emergency stop buttons, anti-collision sensors, and limit switches to ensure the safety of personnel and cargo.

[0003] However, existing electric multi-functional handling platforms primarily rely on robotic arms to grasp and place materials. Specifically, the robotic arm must precisely grasp materials with its end effector and then transfer them to a designated area on the platform. To ensure smooth grasping and avoid material compression and other potential failures, operators must ensure ample space when stacking materials.

[0004] Although this mode of operation ensures the stability of grasping, it also brings significant disadvantages. Due to the limited loading area of the handling platform, the reserved gap directly leads to a significant reduction in the number of materials that can be loaded at a time. Assuming a standard-sized handling platform, theoretically it can load 100 closely arranged material boxes. However, in actual operation, after reserving gaps due to grasping requirements, the loading capacity may drop to 60-70, and the loading efficiency will be reduced by about 30%-40%. As the frequency of handling increases, this efficiency loss will be further amplified, seriously restricting the overall operation progress. Especially in scenarios such as large-scale warehousing and logistics centers and automated production lines that require large-scale and high-frequency handling, existing technologies are difficult to meet the growing demand for efficient handling, becoming a key bottleneck restricting the improvement of production efficiency. Summary of the Invention

Before loading materials, the carrying array is adjusted to an extended state by the driving mechanism, so that the carrying parts are dispersed from each other and an interval space is formed between two adjacent carrying parts, which is convenient for a robot to grab and place materials on the carrying parts. After loading materials, the carrying array is converted to a closed state by the driving mechanism, so that the carrying parts are close to each other and the interval space is eliminated, thereby greatly improving the single handling volume and space utilization.

[0030] Electric multi-functional handling platforms in related technologies primarily rely on robotic arms to perform material grabbing and placement operations. The robotic arm precisely grips materials using its end effector. During material transfer to a designated area, operators must ensure sufficient clearance when stacking materials to avoid material contact and collisions between materials, or to prevent the robotic arm from interfering with stacked materials during movement. This clearance must accommodate the robotic arm's range of motion for movements such as extension and rotation, while also ensuring that the end effector does not contact other materials when grabbing and placing them. However, this operating method conflicts with the platform's limited loading area. While the platform's original design aims to accommodate as many materials as possible, to provide space for the robotic arm, materials cannot be tightly packed together. For example, a standard-sized platform can theoretically hold 100 boxes of materials tightly together. However, due to the reserved gripping space, the actual loading capacity drops sharply to 60-70 boxes, reducing loading efficiency by 30%-40%. As the frequency of handling increases, this efficiency loss amplifies exponentially. This is especially true in scenarios requiring large-scale, high-frequency handling, such as large-scale warehouses and logistics centers and automated production lines, where existing technologies struggle to meet the demands for efficient operations. The root cause is the rigid operating space requirements of the robotic gripping mode, which fundamentally conflicts with the goal of maximizing the space utilization of the handling platform. Each gripping action by the robotic gripper requires its own dedicated operating space, while the handling platform must fully utilize every available surface area for loading materials. This makes it difficult to balance "grasping stability" with "loading efficiency," creating a critical technical bottleneck hindering improved production efficiency.

[0031] Based on this, in order to improve the problem in the related art that the electric multi-functional transport platform needs to reserve operating space when transporting materials, resulting in a significant reduction in airborne utilization, the embodiment of the present application provides the following solution.

[0032] Please also refer to Figure 1 and Figure 2 The embodiment of the present application provides an electric multifunctional transport platform 100, comprising a vehicle body 10, a platform frame 20, a plurality of loading portions 30, a plurality of flexible connection structures 40 and a drive mechanism 50, wherein: The vehicle body 10 is an electric multifunctional mobile vehicle. A platform frame 20 is arranged on the top of the vehicle body 10.

[0033] The loading sections 30 are arranged in a matrix to form a loading array; the two loading sections arranged diagonally in the loading array are respectively the first loading section 31 and the second loading section 32, the first loading section 31 is fixedly set on the platform frame 20, and the remaining loading sections 30 are movably set on the platform frame 20.

[0034] Any two adjacent loading portions 30 are connected by at least one flexible connection structure 40 , so that the loading portions 30 can be brought closer together to put the loading array in a closed state, and can be spread apart to put the loading array in an extended state.

[0035] The driving mechanism 50 is disposed on the vehicle body 10 or the platform frame 20 , and a power output end of the driving mechanism 50 is connected to the second loading portion 32 for driving the loading array to switch between the folded state and the extended state.

[0036] It can be understood that the vehicle body 10 is the main part of the electric multi-functional transport platform 100, for example, it can be various types of electric multi-functional mobile vehicles.

[0037] The loading portion 30 is a structural component for loading materials, and may be, for example, a loading frame or a loading plate.

[0038] The flexible connection structure 40 is a component that connects adjacent load-bearing sections 30. For example, the flexible connection structure 40 may include a connector with limiting flanges at both ends and a connection hole defined in the side of the load-bearing section. The opposite ends of the connector slideably engage with the connection holes on the two adjacent load-bearing sections, and the limiting flanges abut against flanges within the connection holes to prevent the connector from disengaging from the connection holes. The flexible connection structure 40 may also include a connector with an annular groove defined on its outer circumference and a connection hole defined in the side of the load-bearing section. The opposite ends of the connector slideably engage with the connection holes on the two adjacent load-bearing sections, and the inner wall of the connection hole is provided with an elastic snap, which engages with the annular groove on the outer circumference of the connector.

[0039] The driving mechanism 50 is a mechanism for driving the object array to move, and may be, for example, an electric push rod, a hydraulic cylinder, or a motor screw assembly.

[0040] The first loading portion 31 can be fixedly mounted on the platform frame 20 in a variety of ways, such as by bolting, welding, or riveting. The remaining loading portions 30, excluding the first loading portion 31, can be movably mounted on the platform frame 20 by means of sliding connections, rolling connections, or other movable means.

[0041] From the above, it can be seen that the electric multifunctional transport platform provided in the embodiment of the present application enables the carrier array to switch between a "closed state" and an "extended state" through the coordinated design of the matrix-arranged carrier parts 30, the flexible connection structure 40 and the drive mechanism 50: in the closed state, each carrier part 30 is tightly fitted through the flexible connection structure 40 to form a compact matrix to minimize space occupancy; during the extension process of the carrier array, the drive mechanism 50 drives the second carrier part 32 to pull each carrier part 30, so that each carrier part 30 is expanded to the maximum spacing through the connection of the flexible connection structure 40, so that the carrier array is in an extended state, which is convenient for placing or grabbing materials; after the operation is completed, the drive mechanism 50 drives the second carrier part 32 to pull the carrier array to the closed state, restoring the compact shape. Among them, the first loading part 31 is fixed to the platform frame 20 as a reference fulcrum, and the other loading parts 30 are linked through the flexible connection structure 40 to achieve synchronous extension, avoiding the space waste caused by the reserved fixed operating space or fixed spacing layout of the traditional platform, simplifying the operation process, and ensuring that the load-bearing area is maximized in the extended state and the transportation space is minimized in the closed state, improving the problem of reduced space utilization caused by the reserved operating space of the traditional platform.

[0042] In some embodiments, please refer to Figures 3 and 4 In the closed state and the extended state, each loading portion 30 is on the same horizontal plane.

[0043] It can be understood that the various loading parts 30 are in the same horizontal plane means that when the driving mechanism 50 drives the various loading parts 30 to realize the closed state or the extended state through the flexible connection structure 40, the load-bearing surfaces of the various loading parts 30 are supported by the platform frame 20 and constrained by the flexible connection structure 40 to maintain a high consistency without vertical misalignment.

[0044] With such an arrangement, in the closed state, the design of the same horizontal plane enables the loading part 30 to fit tightly, avoiding invalid gaps caused by height misalignment, maximizing the overall space occupied by the platform, and preventing materials from sliding or tipping over due to height differences during the extension or closing of the loading array, reducing the demand for buffer space reserved to prevent material deviation, and at the same time simplifying the adaptation difficulty of the automated grasping equipment, so that the equipment can be operated accurately without additional height adjustment, avoiding waste caused by reserved space in the equipment's range of activity, thereby improving space utilization from both the aspects of tight material arrangement and operation adaptation.

[0045] Optionally, in some embodiments, see Figures 3 and 4 The length direction of the object carrier array is parallel to the length direction of the vehicle body 10, and the width direction of the object carrier array is parallel to the width direction of the vehicle body 10, and the length direction of the object carrier array is perpendicular to the width direction of the object carrier array.

[0046] It can be understood that the length direction of the object array refers to the direction of the long side of the object array along the entire object array, and the width direction of the object array refers to the direction of the short side of the object array along the entire object array.

[0047] The length direction of the vehicle body 10 is parallel to the moving direction of the vehicle body 10 , and the width direction of the vehicle body 10 is perpendicular to the moving direction of the vehicle body 10 .

[0048] This arrangement maximizes space utilization while minimizing operating space by strictly aligning the length and width of the loading array with the vehicle body 10 and maintaining a perpendicular relationship. When closed, the loading array fits snugly against the vehicle body 10, avoiding margin gaps caused by directional misalignment. When extended, the neatly orthogonal layout allows materials to be tightly arranged without requiring spacing due to directional deviations, significantly improving space utilization.

[0049] Optionally, in some embodiments, see Figure 1 、 Figure 2 and Figure 5 The electric multifunctional transport platform 100 also includes a rolling support component 60. Each carrying part 30 is provided with a rolling support component 60 on the side facing the platform frame 20, so that a rolling pair is formed between the contact surface of the rolling support component 60 and the platform frame 20, and a spacing space is formed between the carrying part 30 and the platform frame 20, and the driving mechanism 50 is located in the spacing space.

[0050] It can be understood that the rolling support component 60 is a component used to reduce the friction resistance of the loading part 30 when it moves, support the weight of the loading part 30 and maintain the smoothness of movement, and can be, for example, a universal wheel, a ball or a roller.

[0051] The side of each loading portion 30 facing the platform frame 20 refers to the side of each loading portion 30 opposite to the platform frame 20 , that is, the surface of the loading portion 30 close to the platform frame 20 when installed.

[0052] The separation space refers to a gap for accommodating the driving mechanism 50 formed between the loading portion 30 and the platform frame 20 due to the provision of the rolling support component 60 on the side of the loading portion 30 facing the platform frame 20 .

[0053] This arrangement, by providing a rolling support component 60 between the load-carrying portion 30 and the platform frame 20 to form a rolling pair, and arranging the drive mechanism 50 in the spacing space, significantly improves space utilization. The rolling support component 60 requires only a small friction gap when the load-carrying portion 30 moves, significantly reducing the reserved space for movement compared to traditional sliding structures, and can achieve a tight fit of the load-carrying portion 30 in the closed state, compressing the overall occupied space; the drive mechanism 50 is built into the spacing space, avoiding the external drive device occupying the top and surrounding operating space of the platform frame 20, so that the top of the platform frame 20 can be fully used for material loading. In addition, the regular layout optimizes the material loading area, facilitates the close arrangement of materials, reduces the spacing waste caused by the protrusion of structural components, and effectively improves the problem of low utilization of traditional platforms due to reserved operating space, achieving the unity of compact structure and efficient load-carrying.

[0054] Optionally, see Figure 6 The rolling support component 60 is a universal wheel.

[0055] A universal wheel is a wheel capable of 360-degree rotation on a horizontal plane. It consists of a wheel body, a steering shaft, and a fixed bracket. The wheel body rotates around its own axis, allowing it to roll forward, while the steering shaft allows the wheel body to swing freely horizontally, changing its direction of motion. Compared to conventional fixed wheels, universal wheels offer greater flexibility, enabling objects to be easily moved in any direction within a two-dimensional plane.

[0056] With this arrangement, the multi-directional rotation characteristics of the universal wheels allow the loading portion 30 to flexibly adjust its movement direction during extension or folding, without the need to reserve additional space to accommodate steering or angle deviations, further reducing space waste compared to traditional fixed-direction support structures.

[0057] For example, see Figure 7 The flexible connection structure 40 includes a connector 401 and a connection hole 301 formed on the side of the loading portion 30. The connector 401 is movably connected to the connection holes 301 on two adjacent loading portions 30. The loading portion 30 has connection holes 301 formed on at least two adjacent side walls thereof, and each connection hole 301 on each side wall of the loading portion 30 is movably connected to a corresponding connection hole 301 on the loading portion 30 via the connector 401.

[0058] It can be understood that the connecting member 401 is a component that is movably connected to the connecting hole 301 of the adjacent loading portion, and can be, for example, an elastic connecting rod or a pin.

[0059] The connection hole 301 is a hole-shaped structure formed on the side of the loading portion 30 and is used for being movably connected to the connection piece 401 of the flexible connection structure 40 so that adjacent loading portions 30 can be brought closer to or dispersed from each other.

[0060] This arrangement, by providing connection holes 301 on at least two adjacent side walls of the loading section 30 and utilizing connectors 401 to flexibly connect with the connection holes 301 of adjacent loading sections, allows each loading section 30 to deform in tandem with adjacent loading sections 30 within a two-dimensional plane. In the closed state, the loading sections 30 are tightly bound together by the constraints of the connectors 401, forming a compact loading array. In the extended state, the multi-directional connectors 401 stretch synchronously, allowing the loading array to evenly expand into a regular plane, thus avoiding uneven deformation or localized space waste caused by a single connection direction. This multi-directional connection design enhances the morphological stability of the loading array and reduces the safety space required to avoid structural sway or inconsistent deformation, thereby effectively improving the low space utilization of traditional platforms due to a single connection method.

[0061] In some embodiments, see Figure 7 , the connecting member 401 is a flexible connecting rod that can undergo elastic deformation.

[0062] It can be understood that the flexible connecting rod is a rod-shaped component that can undergo elastic deformation, for example, it can be made of elastic materials such as spring steel or rubber-reinforced composite materials.

[0063] This arrangement utilizes elastically deformable flexible links as connectors 401. The elastic properties of these links allow adjacent loading sections 30 to be brought together during closing, reducing the play required by traditional rigid connections. In the extended state, the elastic deformation of the flexible links allows for appropriate dispersion and expansion of the loading sections 30, alleviating the spatial limitations imposed by rigid connections. Through the elastic linkage of the flexible links, the loading array remains compact and organized in all states, reducing the ineffective space created by the rigid constraints of the connection structure. This effectively improves the low spatial utilization inherent in traditional platforms due to the lack of deformable connection methods.

[0064] Optionally, in some embodiments, see Figure 7 A limiting portion 4011 is provided at one end of the connecting member 401 located in the connecting hole 301 , and a limiting fitting portion 3011 is provided on the inner wall of the connecting hole 301 , which is used to limit the limiting portion 4011 from moving out of the connecting hole 301 .

[0065] It can be understood that the limiting portion 4011 is a structural component provided at one end of the connecting member 401 located in the connecting hole 301. The limiting portion 4011 mainly prevents the connecting member 401 from escaping from the connecting hole 301. For example, it can be a protrusion, a flange or a block.

[0066] The position-limiting mating portion 3011 is provided on the inner wall of the connection hole 301 and cooperates with the position-limiting portion 4011 to limit the position-limiting portion 4011 from moving out of the connection hole 301. The shape and size of the position-limiting mating portion 3011 are compatible with the position-limiting portion 4011, and can be, for example, a groove, a slot, an annular position-limiting surface, or a protruding structure.

[0067] This arrangement, by providing a limiting portion 4011 at one end of the connector 401 and a limiting mating portion 3011 on the inner wall of the connection hole 301, forms a mechanical limiting structure, allowing the connector 401 to be stably connected to the connection hole 301, preventing the loading portion 30 from loosening or falling off due to the connector 401 being dislodged. In the closed state, the limiting portion 4011 and the limiting mating portion 3011 allow adjacent loading portions 30 to fit tightly together, eliminating the need to reserve an additional safety gap to prevent the connector 401 from detaching. In the extended state, the limiting mating portion 3011 limits excessive movement of the connector 401, preventing deformation of the load-bearing surface or material slippage due to connection failure, thereby reducing the operating space reserved to cope with connection instability. This reliable limiting design improves the structural stability of the loading array in different states, ensuring that the platform space is always efficiently used for material loading, effectively improving the problem of low space utilization due to insufficient connection reliability in traditional platforms.

[0068] Optionally, see Figure 7 The limiting portion 4011 is a limiting protrusion, and a side groove 3012 is opened on the inner wall of the connecting hole 301 . The end wall of the side groove 3012 forms a limiting matching portion 3011 for resisting the limiting portion 4011 .

[0069] It can be understood that the limiting protrusion is a protruding structure provided at the end of the connecting member 401, and can be, for example, a cylindrical, hemispherical or rectangular protrusion.

[0070] The side groove 3012 is a non-through groove provided on the inner wall of the connecting hole 301. It is only concave in a local area of the inner wall of the connecting hole 301 and does not penetrate the outer surface of the loading part 30 where the opening of the connecting hole 301 is located. For example, it can be a semicircular or rectangular groove. The extension direction of the side groove 3012 is perpendicular to the insertion direction of the connecting piece 401.

[0071] This arrangement, by providing a limiting protrusion on the connector 401 and opening a side groove 3012 on the inner wall of the connecting hole 301, uses the end wall of the side groove 3012 as a limiting mating portion 3011 to resist the limiting protrusion, thus forming a reliable mechanical limiting structure. In the closed state, the limiting protrusion is blocked by the end wall of the side groove 3012, allowing adjacent load-bearing sections 30 to fit tightly together, eliminating the need for additional safety gaps to prevent the connector 401 from slipping out. In the extended state, the end wall of the side groove 3012 restricts excessive movement of the limiting protrusion, preventing the load-bearing sections 30 from being misaligned or increasing the spacing due to loosening of the connector 401. This limiting design reduces the redundant space reserved due to insufficient reliability in traditional connection structures through precise geometric constraints, allowing the load-bearing array to remain compact and regular in different states, thereby improving the effective utilization of space.

[0072] For example, the loading part 30 can be split into two parts along the central axis of the connecting hole 301, each part corresponds to the semicircular groove structure of the connecting hole 301 and is provided with a guiding slope, first insert the connecting piece 401 into the semicircular groove of one part of the loading part (the limiting protrusion is located in the reserved notch), and then align the two parts of the loading part through the mortise and tenon structure or positioning pins, and after docking, the semicircular grooves are spliced into a complete connecting hole 301, the limiting protrusion slides into the side groove 3012 and abuts against the limiting matching part 3011, and finally, the two parts of the loading part are fixed with a hidden bolt or a snap-on locking structure to achieve interference-free assembly and stable connection.

[0073] In some embodiments, see Figure 6 , the driving mechanism 50 is an electric push rod.

[0074] It can be understood that the electric push rod is an electric drive device that drives the object array to switch between the closed state and the extended state.

[0075] With this arrangement, the linear reciprocating motion characteristics of the electric push rod can be utilized to precisely control the switching of the load array between the closed and extended states. In the closed state, the electric push rod retracts to its shortest stroke, driving the load array to close tightly, minimizing the overall space occupied by the platform. In the extended state, the electric push rod extends to its maximum stroke at a time, allowing each load section 30 to expand to its maximum spacing through the connection of the flexible connection structure 40, eliminating the need for multiple gear adjustments or intermediate state pauses, and avoiding the redundant space reservation caused by the travel uncertainty of traditional drive devices. In addition, the compact structure of the electric push rod can be integrated into the space between the load section 30 and the platform frame 20, without occupying the material-carrying area at the top of the platform frame 20. Through this efficient and precise drive method, the platform frame 20 does not need to reserve additional space for the motion range or adjustment margin of the drive mechanism 50, thereby effectively improving the problem of low space utilization caused by the inefficient drive method of traditional platforms.

[0076] In some embodiments, see Figure 6The electric multifunctional transport platform 100 further includes a universal ball joint 70 and a horizontal rolling component 80 .

[0077] The fixed end 501 of the electric push rod is connected to the platform frame 20 through a universal joint 70, and the telescopic end 502 of the electric push rod is hinged to the second loading part 32; in the closed state, the axis of the electric push rod is consistent with the diagonal direction of the first loading part 31 and the second loading part 32 of the loading array.

[0078] The horizontal rolling component 80 is rotatably disposed on the telescopic end 502 of the electric push rod, and the rotation axis of the horizontal rolling component 80 is perpendicular to the moving plane of the second loading portion 32 . The outer edge of the horizontal rolling component 80 exceeds the side profile of the second loading portion 32 .

[0079] It can be understood that the universal joint 70 is a connection component that allows components to rotate relative to each other in multiple directions. It is usually composed of a sphere and a socket. The sphere can rotate freely in the socket to achieve multi-angle swing in three-dimensional space.

[0080] The horizontal rolling component 80 is a component rotatably disposed on the telescopic end 502 of the electric push rod, and its rotation axis is perpendicular to the moving plane of the second loading part 32 , and can be, for example, a horizontal wheel or a ball.

[0081] With this arrangement, through the universal joint 70 at the fixed end 501 of the electric linear actuator, the horizontal rolling component 80 at the telescopic end 502 of the electric linear actuator, and the diagonal drive layout that aligns the axis of the electric linear actuator with the diagonal direction of the first and second loading portions 31 and 32 of the loading array, if the loading array encounters an obstacle during extension, the horizontal rolling component 80 can first contact the obstacle, reduce the impact through rolling friction, and guide the loading array through the universal joint 70 to change its motion path, causing the loading array to stop extending toward the side with the obstacle and continue extending toward the side without the obstacle (for example, if the loading array encounters an obstacle in the longitudinal direction of the loading array during extension, the horizontal rolling component 80 first contacts the obstacle and reduces the impact through rolling friction, and guides the loading array through the universal joint 70 to stop extending in the longitudinal direction of the loading array and continue extending in the width direction of the loading array), thereby avoiding extension stagnation caused by rigid collisions or reserving a fixed safety distance for avoiding obstacles. At the same time, the diagonal drive layout makes the electric push rod stroke correspond to the diagonal length of the array, shortening the transmission path and accommodating the electric push rod in the space between the platform frame 20 and the loading part 30, thereby improving the low space utilization problem of traditional platforms caused by rigid drive, static obstacle avoidance and inefficient transmission layout.

[0082] In some embodiments, see Figure 2 and Figure 4When the loading array is in an extended state, the center of gravity of any loading part 30 is on the platform frame 20 along the height direction projection of the electric multi-functional transport platform 100, and the distance between the center of gravity of the loading part 30 and the edge of the platform frame 20 is greater than zero.

[0083] It can be understood that the projection along the height direction refers to vertically projecting the center of gravity of the loading portion 30 onto the horizontal plane where the platform frame 20 is located, with the horizontal plane of the electric multifunctional transport platform 100 as a reference.

[0084] With such an arrangement, by limiting the load array in the extended state, the center of gravity of all load parts 30 projected along the height direction of the electric multi-functional transport platform 100 is located within the platform frame 20 and all load parts 30 maintain a safe distance from the edge of the platform frame 20, thereby avoiding the risk of collapse due to outward shift of the center of gravity. There is no need to reserve additional safety space or increase the frame size to balance the center of gravity like traditional platforms, so that the load parts 30 can be moderately expanded outside the edge of the platform frame 20 and adjacent load parts 30 are closely arranged, reducing safety redundancy and invalid gap occupation, improving the effective load-bearing area and space utilization, and improving the space waste problem of traditional platforms that require reserved operating space due to insufficient center of gravity control.

[0085] In some embodiments, see Figure 2 and Figure 4 When the loading array is in an extended state, the loading parts 30 in the loading array that are in the same column and row as the second loading part 32 and the second loading part 32 protrude beyond the edge of the platform frame 20 in the horizontal direction, and the loading part 30 protruding beyond the edge of the platform frame 20 in the horizontal direction includes a first part and a second part, the first part is closer to the first loading part 31 than the second part, and the weight of the first part is greater than the weight of the second part, so that the center of gravity of the loading part 30 is projected onto the platform frame 20 along the height direction of the electric multi-functional transport platform 100.

[0086] It can be understood that protruding horizontally beyond the edge of the platform frame 20 means that when the loading portion 30 is in the extended state, part of the structure exceeds the horizontal projection boundary of the platform frame 20 .

[0087] The first part refers to the proximal end of the loading portion 30, and the second part refers to the distal end of the loading portion 30. Each loading portion 30 is divided into two parts along the bisecting plane, wherein the front half closer to the first loading portion 31 is the proximal end (i.e., the first part), and the other part is the distal end (i.e., the second part). The bisecting plane is parallel to the length direction of the loading array and perpendicular to the width direction of the loading array, and the bisecting plane divides the width of the loading portion in half.

[0088] The first portion being heavier than the second portion means that the center of gravity of the load-carrying portion 30 protruding from the platform frame 20 is adjusted through mass distribution. For example, this can be achieved by using different materials or structures. If different materials are used to adjust the center of gravity, the first portion can be made of a metal material such as steel or cast iron, while the second portion can be made of a lightweight material such as aluminum alloy, carbon fiber, or engineering plastic. By leveraging this material density difference, the first portion can have a significantly greater unit volume weight than the second portion, thereby shifting the center of gravity toward the first portion. If different structures are used to adjust the center of gravity, a solid metal counterweight (such as a lead or iron block) can be placed within the first portion, or the load-carrying portion 30's bearing layer can be thickened, while the second portion can have a hollow cavity structure or a hollow design (such as a honeycomb-shaped weight-reducing hole) to shift the center of gravity toward the first portion.

[0089] In this way, by designing the loading part 30 protruding outside the platform frame 20 so that the weight of the first part close to the first loading part 31 is greater than the weight of the second part away from the first loading part 31, the center of gravity of the loading part 30 is projected into the platform frame 20 by utilizing the weight distribution with the proximal part being heavy and the distal part being light. There is no need to limit the protruding distance of the loading part 30 or increase the size of the platform frame 20 for fear of outward shifting of the center of gravity as in traditional platforms. This allows the loading part 30 to expand moderately outside the platform frame 20 and adjacent loading parts 30 to be arranged closely, reducing the safety space reserved for balancing the center of gravity and the invalid gap between the loading parts, thereby improving the effective load-bearing area and space utilization, and improving the space waste problem of traditional platforms due to the need to reserve operating space due to center of gravity control.

[0090] In some embodiments, see Figure 2 and Figure 4 When the object carrier array is in the extended state, the object carriers 30 in the object carrier array and the second object carrier 32 in the same column and row as the second object carrier 32 protrude beyond the edge of the platform frame 20 in the horizontal direction.

[0091] The length of the connecting member 401 is configured so that when the loading array is in an extended state, by limiting the relative displacement of two adjacent loading parts 30, the center of gravity of any loading part 30 is always projected on the platform frame 20 along the height direction of the electric multi-functional transport platform 100.

[0092] It can be understood that the relative displacement refers to the maximum distance change between adjacent loading parts 30 along the axis direction of the connecting member 401 during the closing or extending process.

[0093] In this way, by configuring the length of the connecting part 401 to limit the relative displacement of adjacent loading parts 30, during the extension of the loading array, the protruding distance of the loading part 30 is effectively constrained, so that the projection of the center of gravity of each loading part 30 along the height direction of the electric multi-functional transport platform 100 is always within the platform frame 20, avoiding the center of gravity shift due to excessive protrusion of the loading part 30 and reserving a large amount of safe operating space. Compared with traditional platforms, there is no need to expand the size of the platform frame 20 or increase the safety distance to balance the center of gravity, so that the loading array can be compactly extended, thereby effectively improving the space utilization of the platform when transporting materials.

[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 and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
