Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The transport trolley 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0041] like Figures 1-3 As shown, the transport trolley 100 according to an embodiment of the present utility model includes a trolley body 1 and a column 2.

[0042] Among them, the vehicle body 1 is movable. It can be understood that the vehicle body 1 undertakes the movement function of the entire transport vehicle 100. The vehicle body 1 can use autonomous navigation technology in conjunction with the drive system to enable the transport vehicle 100 to move autonomously in places such as factories and warehouses.

[0043] For example, the vehicle body 1 includes components such as drive wheels, control system, and sensors, and can automatically adjust its driving direction and speed through environmental perception and path planning system to perform material transportation tasks in different working environments.

[0044] The column 2 is connected to the trolley body 1 and extends vertically. It is understood that the column 2 provides a structurally stable and easy-to-operate platform for the transport trolley 100, and can provide installation positions for other components (control modules or the first pallet 3). Simultaneously, because the column extends vertically, control modules (such as the first emergency stop button 23, display screen 22, first switch 24, etc.) can be placed in reasonable positions, reducing the need for operators to bend over or lower their heads to operate, making it easier for operators to access these functional modules, thereby improving operational comfort and safety.

[0045] In addition, the column 2 can effectively improve the stability and overall structural strength of the transport trolley 100, enabling the transport trolley 100 to maintain high stability during operation, especially when the trolley body 1 is carrying materials.

[0046] In addition, different structures can be set on the column 2 to meet the customized needs of different customers, thereby improving the flexibility and versatility of the transport trolley 100.

[0047] According to an embodiment of the present invention, the transport trolley 100 has a movable trolley body 1 connected to a column 2. The column 2 provides a structurally stable and easy-to-operate platform for the transport trolley 100. By extending vertically, the structure on the column 2 is positioned appropriately, reducing the need for operators to bend over or lower their heads, and making it easier for operators to access the structure on the column 2, thereby improving operational comfort and safety. Simultaneously, the presence of the column 2 effectively enhances the stability and overall structural strength of the transport trolley 100, ensuring high stability during operation. Furthermore, different structures can be incorporated into the column 2 to meet the customized needs of different customers, improving the flexibility and versatility of the transport trolley 100 and satisfying diverse requirements.

[0048] In some embodiments of this utility model, such as Figures 1-6As shown, the transport trolley 100 also includes a first pallet 3. The first pallet 3 is connected to the column 2. Thus, the first pallet 3 allows the transport trolley 100 to place materials to be transported on it, enhancing the load-bearing capacity of the transport trolley 100. Furthermore, the connection between the first pallet 3 and the column 2 ensures that the first pallet 3 is stably installed on the column 2, thereby providing a reliable load-bearing platform.

[0049] It should be noted that the connection between the first pallet 3 and the upright 2 can be achieved by means of bolts, welding or clips, so that the first pallet 3 can remain stable during transportation and will not shift due to vibration or external force.

[0050] In some embodiments of this utility model, such as Figures 1-6 As shown, the relative position of the first pallet 3 and the upright 2 is fixed. Therefore, the connection between the first pallet 3 and the upright 2, and their fixed relative position, ensures that the first pallet 3 will not change position or shift during use, thereby ensuring the stability of the materials and the safety of transportation.

[0051] It should be noted that the method of fixing the first pallet 3 to the column 2 is not limited here. For example, bolts, clips, welding, etc. are acceptable, as long as the relative position of the first pallet 3 and the column 2 is fixed and the first pallet 3 can provide a stable and safe bearing platform for the materials.

[0052] In some embodiments of this utility model, such as Figures 1-6 As shown, the position of the first pallet 3 relative to the column 2 is adjustable along the height direction of the column 2. Therefore, the operator can adjust the height of the first pallet 3 according to actual needs, thereby adapting to different material transportation requirements. This allows the transport trolley 100 to flexibly handle conveyor lines or material stacking areas of different heights, improving the applicability and flexibility of the transport trolley 100.

[0053] In some embodiments of this utility model, such as Figures 4-6 As shown, along the height direction of the column 2, the column 2 has multiple sets of mounting holes 21 spaced apart. The first tray 3 is connected to one set of mounting holes 21. Thus, the first tray 3 is connected to the column 2 through one set of mounting holes 21, allowing the first tray 3 to be fixed at different heights. The spaced arrangement of the multiple sets of mounting holes 21 provides more options. The operator can freely select the appropriate mounting hole 21 to fix the first tray 3 according to different material heights or transportation needs. This makes the position of the first tray 3 relative to the column 2 adjustable along the height direction of the column 2, making the installation of the first tray 3 on the column 2 more flexible, adapting to the height requirements of different scenarios, while ensuring the stability and robustness of the first tray 3.

[0054] In some embodiments of this utility model, such as Figures 1-4 As shown, the first tray 3 is movable along the height direction of the column 2 and can be fixed at any position along the height direction of the column 2. Therefore, this arrangement allows the position of the first tray 3 relative to the column 2 to be adjustable along the height direction of the column 2, making the installation of the first tray 3 on the column 2 more flexible and adaptable to the height requirements of different scenarios.

[0055] For example, the column 2 is provided with a guide rail extending along the height direction of the column 2, and the first tray 3 is equipped with a slider that cooperates with the guide rail. The slider can slide along the length direction of the guide rail, and the height of the tray can be adjusted above the column 2 by sliding; or, the column 2 is provided with multiple slots arranged at intervals, and the first tray 3 is provided with a connector that can be inserted into the slot. The connector cooperates with the slot through a spring mechanism. Each time the height of the tray is adjusted, the inserted connector and the spring mechanism lock in the desired slot position, thereby fixing the position of the first tray 3.

[0056] In some embodiments of this utility model, such as Figure 3 and Figure 7 As shown, a first clearance groove 311 is provided in the middle area of ​​the first pallet 3, and at least a portion of the upright 2 is located within the first clearance groove 311. Thus, by designing the first clearance groove 311 to accommodate at least a portion of the upright 2, the upright 2 and the first pallet 3 can be tightly connected, reducing interference between the upright 2 and the first pallet 3, thereby improving the stability and load-bearing capacity of the overall structure and ensuring the stability of the first pallet 3 during transportation.

[0057] In some embodiments of this utility model, such as Figure 3 , Figure 6 and Figure 7 As shown, the first pallet 3 includes a first pallet body 31 and a support member 32. The support member 32 is connected to the upright 2, and the first pallet body 31 is positioned above the support member 32. Thus, the support member 32 stabilizes the installation position of the first pallet body 31, ensuring a stable installation position and preventing displacement or instability during transportation.

[0058] In some embodiments, such as Figure 3 , Figure 6 and Figure 7 As shown, along the height direction of the column 2, the column 2 has multiple sets of mounting holes 21 spaced apart, and the support member 32 is connected to one set of mounting holes 21. Thus, the support member 32 is connected to the column 2 through one set of mounting holes 21, thereby fixing the first tray 3 at different height positions, thus realizing that the position of the first tray 3 relative to the column 2 is adjustable along the height direction of the column 2.

[0059] In some embodiments, such as Figure 7 As shown, the first clearance groove 311 is provided on the first pallet body 31 so that at least a portion of the upright 2 is located in the first clearance groove 311.

[0060] In some embodiments of this utility model, such as Figure 3 and Figure 7 As shown, a first anti-slip mat 312 is provided above the first pallet 3. It can be understood that the first anti-slip mat 312 is usually made of silicone rubber or other high-friction materials, which can provide sufficient friction. When the transport trolley 100 is running or stopped, the first anti-slip mat 312 can increase the friction between the material and the first pallet 3, effectively preventing the material from sliding due to inertia, thereby helping the material to remain stable.

[0061] In some embodiments of this utility model, such as Figure 3 and Figure 7 As shown, the outer edge of the first pallet 3 is provided with a first guardrail 313 extending along the circumferential direction of the first pallet 3, or multiple first guardrails 313 spaced apart along the circumferential direction of the first pallet 3. Thus, the first guardrails 313 effectively prevent materials on the first pallet 3 from slipping off, ensuring material safety. At the same time, the first guardrails 313 can be a single one extending along the circumferential direction of the first pallet 3 or multiple ones spaced apart along the circumferential direction of the first pallet 3, improving versatility.

[0062] In some embodiments of this utility model, such as Figure 7 As shown, a first anti-slip mat 312 is provided above the first pallet 3, and a first guardrail 313 extending along the circumference of the first pallet 3 or multiple first guardrails 313 spaced apart along the circumference of the first pallet 3 are provided on the outer edge of the first pallet 3. Thus, when the transport trolley 100 is running or stopped, the first anti-slip mat 312 firstly increases the friction between the material and the first pallet 3, and the first guardrail 313 provides secondary protection, further preventing the material from slipping off the first pallet 3 and ensuring the safety of the material.

[0063] In some embodiments, such as Figure 3 and Figure 7 As shown, the first pallet 3 includes a first pallet body 31 and a support member 32. The support member 32 is connected to the upright 2, the first pallet body 31 is located above the support member 32, the first anti-slip mat 312 is located on the first pallet body 31, and the first guardrail 313 is located on the first pallet body 31.

[0064] In some embodiments of this utility model, such as Figures 1-5 As shown, the first tray 3 is one or multiple trays spaced apart along the height direction of the column 2.

[0065] like Figures 1-4As shown, when there is only one first pallet 3, the first pallet 3 is fixedly or adjustablely set on the column 2 of the transport trolley 100. This structure is simple, easy to install and disassemble, suitable for the transportation needs of a single type of material, and can provide a stable and centralized bearing platform to ensure the stability of the material during transportation.

[0066] like Figure 5 As shown, when there are multiple first pallets 3, the design of multiple first pallets 3 enables the transport trolley 100 to carry more types or different sizes of materials in the same transport, thereby improving the efficiency of material transport. At the same time, by adjusting the number and spacing of the first pallets 3, the transport trolley 100 can flexibly adapt to the material transport needs of different scenarios, and is particularly suitable for large-volume logistics tasks.

[0067] Therefore, by setting the first pallet 3 as one or more, each adapting to different application scenarios, the transport trolley 100 has a high degree of flexibility in structural design. It can handle simple transport tasks of lightweight materials on a single pallet, and can also achieve efficient transport of batches and diverse materials through a multi-pallet hierarchical structure, meeting the dual requirements of space utilization and transport efficiency in actual industrial scenarios.

[0068] In some embodiments of this utility model, such as Figures 1-6 As shown, the trolley body 1 is equipped with a second pallet 11, and the first pallet 3 and the second pallet 11 are arranged opposite each other in the vertical direction. Therefore, by setting the second pallet 11, the transport trolley 100 can have an additional material carrying platform in addition to the first pallet 3, thereby significantly improving the overall carrying capacity of the transport trolley 100. In scenarios requiring simultaneous handling of multiple batches of materials, material sorting, or vertical layered transportation, it can effectively improve transportation efficiency, reduce the number of round trips of the trolley, enhance the flexibility and multi-task carrying capacity of transportation operations, and thus connect to multiple conveyor lines, improving transportation efficiency and reducing costs.

[0069] Therefore, while meeting the total material transportation needs of the factory / production line, it can help the factory / production line reduce the purchase quantity of transport trolleys 100, reduce the factory's procurement costs, greatly facilitate the factory's automation and intelligent transformation, and reduce costs and increase efficiency for the factory.

[0070] In addition, the first pallet 3 and the second pallet 11 are arranged opposite each other in the vertical direction, which reduces the space occupied by the transport trolley 100 and facilitates the separate placement of materials of different types, sizes or transport purposes, reducing the risk of mixed placement, improving the zoning efficiency and loading rationality of on-site operations, and meeting the diverse loading needs of complex working conditions.

[0071] In some embodiments, such as Figure 2 , Figures 4-6As shown, the second pallet 11 includes a second pallet body 113, a second anti-slip mat 111, and a second guardrail 112. The second pallet body 113 serves as a carrying platform, positioned above and connected to the trolley body 1. The second anti-slip mat 111 is located on the upper surface of the second pallet body 113 and is typically made of a high-friction material (such as silicone rubber or TPE) to provide sufficient friction. During the start-up, acceleration, deceleration, or turning of the transport trolley 100, it effectively prevents materials from sliding on the pallet, thereby improving the safety and stability of the transport process. The second guardrail 112 is located on the outer edge of the second pallet body 113 and is either a continuous surrounding structure or multiple guardrails spaced at intervals along the circumference of the second pallet 11. It provides a second layer of protection for the materials on the second pallet 11. When the second anti-slip mat 111 cannot completely resist slippage, the second guardrail 112 prevents materials from falling, effectively improving transport safety. The second tray body 113 has a third clearance groove 114, and at least a portion of the column 2 is located within the third clearance groove 114.

[0072] In some embodiments of this utility model, such as Figure 3 As shown, the column 2 is equipped with at least one of the following: a display screen 22, a first emergency stop button 23, a first switch 24, and a handle 25. Thus, the column 2 provides a reasonable installation position for the display screen 22, the first emergency stop button 23, the first switch 24, or the handle 25, reducing the need for operators to bend over or lower their heads to operate, making it easier for operators to access these functional modules, thereby improving operational comfort and safety.

[0073] Specifically, the display screen 22 is used to display the operating status information, alarm prompts, and current transportation task information of the transport trolley 100. Through the display screen 22, operators can monitor the transportation situation in real time, improving task response capabilities. The first emergency stop button 23 is used to quickly cut off power in emergencies, ensuring the safety of the transportation process. The first switch 24 includes a power switch 241 and a button 242. The power switch 241 controls the on / off of the main power supply, and the button 242 is used for mode switching, task initiation, and other functions, improving the flexibility of system control. The handle 25 is used to assist manual handling of the transport trolley 100, improving the controllability of the trolley in non-automatic mode.

[0074] In some embodiments of this utility model, such as Figure 3As shown, a display screen 22 is installed on the column 2, which is located on the horizontal wall surface of the column 2 away from the trolley body 1. The display screen 22 can be fixed to the horizontal wall surface of the column 2 away from the trolley body 1 by screws, clips, or guide rail grooves. Through the installation of the display screen 22, the transport trolley 100 can display real-time status information, alarm information, and task instructions to the operator in a visual manner, which enhances the information feedback between the system and the operator, and facilitates timely response and operation adjustment by the operator on site.

[0075] It should be noted that the display screen 22 can be an LED screen, an LCD screen, or a liquid crystal screen, and supports the dynamic display of system status information, alarm prompts, task flow, material number, and other data.

[0076] Furthermore, the display screen 22 is located at the top of the column 2, so that the display screen 22 can be set at a height that is easy to view, reducing the need for operators to bend over or turn to the side to view, and improving operating comfort and efficiency.

[0077] In some embodiments of this utility model, such as Figure 3 As shown, a first emergency stop button 23 is provided on the column 2, located on the wall surface of the column 2 facing away from the trolley body 1 in the horizontal direction. It is understood that the first emergency stop button 23 is used to manually and quickly interrupt the system operation when the transport trolley 100 experiences an abnormal situation (such as a collision, task error, or system malfunction). Its structural design allows operators to accurately touch and trigger the emergency stop function immediately, even in tense situations, ensuring human-machine safety. Simultaneously, the column 2, as a centralized installation platform for functional modules, allows the first emergency stop button 23 to be positioned in a clearly visible and easily accessible location, avoiding delays in emergency stop response due to low-position installation and significantly improving safety protection capabilities.

[0078] In some embodiments of this utility model, such as Figure 3 As shown, a first switch 24 is installed on the upper wall of the column 2. Thus, the column 2 serves as a centralized installation platform for functional modules, allowing the first switch 24 to be positioned in a clearly visible and easily accessible location, avoiding delays in emergency stop response due to low-position installation and significantly improving safety protection capabilities. Specifically, the first switch 24 includes a power switch 241 and a button 242. The power switch 241 is typically a toggle or knob type used to control the power supply to the transport trolley 100, and the button 242 is a function operation button, such as starting a task, switching modes, or resetting a fault.

[0079] In some embodiments of this utility model, such as Figure 3As shown, a handle 25 is provided on the upper end of the column 2. Thus, the handle 25 allows the operator to manually grip and use it in the non-automatic state of the transport trolley 100, during equipment handling, or during fine-tuning of its position, effectively improving the maneuverability and ease of guidance of the trolley, and is especially suitable for narrow passages or obstacle avoidance scenarios.

[0080] In some embodiments of this utility model, such as Figure 3 As shown, the column 2 is located at the front or rear of the trolley body 1. It can be understood that the trolley body 1 is the movable part of the transport trolley 100. By placing the column 2 at the front or rear of the trolley body 1, a location that is easily accessible and away from the material placement area can be provided for the functional modules on the column 2, avoiding interference with other structures of the trolley body 1 or the materials transported by the trolley body 1. This optimizes the structural layout of the transport trolley 100 and improves the rationality of the structural connection between the column 2 and the trolley body 1, as well as the overall operational stability.

[0081] In one specific embodiment, the column 2 is located at the front of the vehicle body 1.

[0082] In some embodiments of this utility model, such as Figure 2 As shown, a second clearance groove 121 is provided in the middle area of ​​the trolley body 1, and at least a portion of the column 2 is located within the second clearance groove 121. It can be understood that the setting of the second clearance groove 121 allows at least a portion of the column 2 to be embedded into the trolley body 1, thereby achieving a more compact connection between the trolley body 1 and the column 2 in terms of structure, reducing the overall space occupied by the exposed part of the column 2, optimizing the overall size and layout of the transport trolley 100, and is especially suitable for use scenarios where structural space is limited or precise arrangement is required.

[0083] Furthermore, the trolley body 1 and the column 2 are detachably connected. When the trolley body 1 and the column 2 are separated, the cover plate of the trolley body 1 is used to cover the second clearance groove 121 to ensure the integrity of the overall structure of the trolley body 1.

[0084] In some embodiments of this utility model, the vehicle body 1 is an AGV vehicle or an AMR vehicle.

[0085] Understandably, both AGVs (Automated Guided Vehicles) and AMRs (Autonomous Mobile Robots) are automated material handling equipment, possessing functions such as autonomous navigation, path planning, and obstacle avoidance. They can achieve efficient automated material transport in application scenarios such as factory workshops and warehouse logistics. AGVs typically rely on ground tracks, magnetic strips, or QR codes for fixed-path navigation, suitable for material transport operations with stable routes and repetitive paths. AMRs, on the other hand, are based on LiDAR, visual navigation, or multi-sensor fusion technology, enabling flexible path planning and autonomous obstacle avoidance, suitable for complex and changing operating environments.

[0086] Therefore, by designing the main body 1 of the transport vehicle 100 as an AGV vehicle or an AMR vehicle, the transport vehicle 100 can be given good autonomous driving ability, enabling it to complete material handling tasks according to task requirements on a preset path or in any scenario.

[0087] In some embodiments of this utility model, such as Figure 6 As shown, the trolley body 1 and the column 2 are detachably connected. Therefore, the trolley body 1 and the column 2 are designed as two relatively independent components, facilitating later maintenance, replacement, and modular upgrades of the transport trolley 100. Specifically, the trolley body 1 and the column 2 can be assembled and connected using screws, bolts, snap-fit ​​structures, or plug-in connectors, allowing for quick assembly and disassembly without affecting overall stability.

[0088] Or, such as Figure 2 As shown, the trolley body 1 includes a trolley shell 12, and the trolley shell 12 and the column 2 are integrated into one piece, thereby improving the overall strength and stability of the transport trolley 100. It is particularly suitable for scenarios with high load requirements or harsh working environments, and avoids structural loosening or deformation caused by assembly tolerances.

[0089] Furthermore, a second clearance groove 121 is provided in the middle region of the car body 12, and at least a portion of the column 2 is located in the second clearance groove 121 so that the column 2 is embedded in the car body 12.

[0090] In some embodiments of this utility model, at least one of a second emergency stop switch and a second switch is provided above the trolley body 1. It is understood that the trolley body 1 is a movable part of the transport trolley 100, and the second emergency stop switch above the trolley body 1 is used to achieve emergency shutdown when the transport trolley 100 encounters abnormal conditions (such as obstacle collision or system failure). The second switch is used to control functions such as main power supply on / off, mode switching, and task initiation.

[0091] It should be noted that the column 2 is equipped with a first emergency stop button 23 and a first switch 24. By additionally setting a second emergency stop switch and a second switch above the trolley body 1, a complementary structure is formed with the first emergency stop button 23 and the first switch 24 on the column 2, a dual control path and redundant safety mechanism can be constructed. Regardless of which side or position the operator is on the transport trolley 100, the equipment can be quickly controlled and stopped, thereby comprehensively improving the responsiveness and safety performance of the transport trolley 100 in complex operating environments.
