[0053] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0054] Currently, in the automotive manufacturing industry, especially in final assembly plants, the design and manufacturing process of pallet trucks typically follows a highly customized model. In this model, each pallet truck is designed specifically for the size and shape of a part, or even for the assembly requirements of a particular vehicle model. The aim is to maximize logistics efficiency and safety, and reduce damage and errors during handling. For example, for a specific part of a particular vehicle model, the dimensions, load capacity, support structure, and load distribution of the pallet truck are carefully designed to ensure the part is securely placed during transport. Simultaneously, the pallet truck's dimensions are precisely matched to the workstations on the production line, the storage space in the warehouse, and the width of the logistics aisles, avoiding unnecessary space waste and handling inconvenience.

[0055] However, this highly customized design strategy reveals some significant drawbacks when faced with changes in production line models or adjustments to logistics planning strategies. These drawbacks primarily manifest in the following ways: once the model changes, the packaging dimensions and shapes of the new model's parts may be completely different from the existing pallet truck design, rendering these customized pallet trucks unusable and thus idle. The scrapping of customized pallet trucks means the need to redesign and manufacture new pallet trucks to meet the new demands, which is not only time-consuming but also costly, including design costs, material costs, and production costs.

[0056] Idle pallet trucks occupy warehouse space, and due to their large size and fixed shape, they are not easy to stack and store, resulting in a significant waste of warehouse space and affecting the normal operation of other logistics activities. The fixed size and shape of traditional pallet trucks cannot be flexibly adjusted according to changes in logistics strategies. For example, when it is necessary to urgently adjust the production line layout or add temporary logistics channels, the fixed size of the pallet trucks may become an obstacle.

[0057] Combination Figures 1 to 7 As shown in the figure, according to a specific embodiment of this application, a modular assembly pallet truck for material transfer is provided.

[0058] Specifically, such as Figure 1As shown, the modular assembly pallet truck for material transfer includes: pallet assembly 30, connecting assembly 40 and caster wheel 60. The connecting assembly 40 is detachably connected to the pallet assembly 30. The connecting assembly 40 has an assembly position for connecting four pallet assemblies 30 together, and a disengagement position for disengaging from the four pallet assemblies 30. At least one caster wheel 60 is provided at the bottom of the pallet assembly 30.

[0059] By applying the technical solution of this embodiment, the pallet truck size can be flexibly adjusted by increasing or decreasing the number of pallet components through the cooperation of pallet component 30 and connecting component 40. This allows the pallet truck to be assembled and disassembled in various configurations, thus facilitating the disassembly and reassembly of pallet components when it is necessary to change the size of the pallet truck or rearrange the layout, solving the problem that the current pallet truck cannot be flexibly adjusted for use.

[0060] Furthermore, such as Figure 2 As shown, the connecting component 40 includes: a first connecting component 41, a second connecting component 43, and an intermediate connecting component 42. The second connecting component 43 is spaced apart from the first connecting component 41, and the first connecting component 41 and the second connecting component 43 are connected by the intermediate connecting component 42. At least one mounting position for mounting the tray component 30 is formed between the second connecting component 43 or the first connecting component 41 and the intermediate connecting component 42.

[0061] The mounting position between the second connecting component 43 or the first connecting component 41 and the intermediate connecting component 42 in this embodiment provides a flexible mounting point for the pallet assembly 30. This means that the pallet assembly can be added or removed longitudinally or laterally according to actual loading needs, thereby easily adjusting the overall size of the pallet truck. This design not only adapts to single-size adjustments, but also enables a wider range of size expansion through the series use of multiple intermediate connecting components, greatly enhancing the adaptability of the pallet truck. The first connecting component 41 and the second connecting component 43 are set at a certain interval and are firmly connected by the intermediate connecting component 42, forming a stable structural frame. This design not only increases the structural strength of the entire pallet truck and reduces shaking during handling and transportation, but also ensures reliable connections between components, guaranteeing the safety of goods even in complex logistics environments.

[0062] The modular design of the connecting component 40 allows users to quickly assemble or disassemble the pallet truck without specialized tools, significantly improving operational efficiency. It enables rapid response to both temporary adjustments to the production line and changes in long-term plans, minimizing production downtime caused by pallet truck adjustments.

[0063] In this embodiment, the mounting positions include a first mounting position, a second mounting position, a third mounting position, and a fourth mounting position. The first mounting position is formed between the first end of the first connecting component 41 and the first end of the intermediate connecting component 42. The second mounting position is formed between the second end of the first connecting component 41 and the second end of the intermediate connecting component 42. The third mounting position is formed between the first end of the second connecting component 43 and the first end of the intermediate connecting component 42. The fourth mounting position is formed between the second end of the second connecting component 43 and the second end of the intermediate connecting component 42. The first mounting position, the second mounting position, the third mounting position, and the fourth mounting position are used to mount at least one tray component 30.

[0064] The presence of four mounting positions in this embodiment provides more options and flexibility for the installation of the pallet assembly 30. This means that the pallet assembly can choose the most suitable installation position according to actual needs, whether it is increasing the number of pallet assemblies to expand the load-bearing area or adjusting the relative positions between pallet assemblies to accommodate goods of different sizes, all can be achieved through these mounting positions. This design allows the pallet truck to quickly adapt to changes in the production line and adjustments in the logistics layout, improving overall logistics efficiency. The first and second mounting positions, and the third and fourth mounting positions are formed at both ends of the connecting assembly, ensuring the uniform distribution of the pallet assembly in the longitudinal and lateral directions. This symmetrical structural design helps maintain the stability of the pallet truck's center of gravity, reduces the risk of swaying and tipping during handling, and improves the safety and stability of cargo transportation.

[0065] In one exemplary embodiment, such as Figure 3 At least one of the first connecting component 41 and the second connecting component 43 includes: a first connecting rod 44 and at least one first overlapping member 45. The first connecting rod 44 extends along a first preset direction, which is the length direction from the first end to the second end of the first connecting component 41. A first mounting position is formed between the first end of the first connecting rod 44 and the first end of the intermediate connecting component 42, and a second mounting position is formed between the second end of the first connecting rod 44 and the second end of the intermediate connecting component 42. At least one first overlapping member 45 is movably connected to the first connecting rod 44, and the first connecting rod 44 is connected to the intermediate connecting component 42 through at least one first overlapping member 45.

[0066] The movable connection between the first overlapping component 45 and the first connecting rod 44 in this embodiment provides structural flexibility. This means that the position of the first overlapping component 45 can be adjusted according to actual needs, thereby adapting to the installation requirements of different pallet components. Users can flexibly adjust the position of the first overlapping component 45 according to the size and shape of the loaded goods and the usage scenario of the pallet truck, thereby dynamically changing the space size of the first and second mounting positions. This design allows the pallet truck to easily adapt to adjustments in the production line or changes in logistics strategies, improving its adaptability and practicality in various operating environments.

[0067] The modular and detachable design of the first overlapping component 45 significantly reduces the difficulty of pallet truck design and maintenance. When specific components need to be replaced or repaired, partial maintenance can be achieved by disassembling the first overlapping component 45 without disassembling the entire pallet truck structure. This saves time, reduces the impact on normal logistics operations, and improves the availability and overall maintenance efficiency of the pallet truck.

[0068] like Figure 4 As shown, the first overlapping component 45 includes: a first sleeve body 452, the first sleeve body 452 is arranged along the axial direction of the first connecting rod 44, a first connecting end 451 is provided on the surface of the first sleeve body 452, and the first sleeve body 452 is detachably connected to the intermediate connecting component 42 through the first connecting end 451.

[0069] In this embodiment, the first overlapping component 45 slides axially on the first connecting rod 44, enabling flexible position adjustment. During pallet truck assembly, the first overlapping component can be quickly positioned according to the size and shape requirements of the loaded goods, thereby changing the size of the first and second mounting positions, enhancing the pallet truck's adaptability and operational efficiency. The precise detachable connection achieved through the first connecting end 451 and the intermediate connecting assembly 42 ensures a stable bond between the first overlapping component and the pallet truck's main frame. Simultaneously, this connection method allows for convenient disassembly and reinstallation when necessary, facilitating regular inspection and maintenance of the pallet truck, timely detection and repair of potential safety hazards, and ensuring safety and cargo integrity during operation.

[0070] In this embodiment, the intermediate connecting component 42 includes an intermediate connecting rod component 421 and a connecting bracket component 422. A portion of the intermediate connecting rod component 421 extends along a first preset direction, and another portion of the intermediate connecting rod component 421 extends along a second preset direction, which is the direction from the first mounting position to the third mounting position. The end of the intermediate connecting rod component 421 extending along the second direction forms a mounting position with the first connecting component 41 or the second connecting component 43. The connecting bracket component 422 is detachably connected to the intermediate connecting rod component 421, and the intermediate connecting rod component 421 is detachably connected to the first connecting component 41 or the second connecting component 43 through the connecting bracket component 422.

[0071] In this embodiment, the intermediate connecting rod assembly 421 extends along a first preset direction and a second preset direction, respectively. This multi-directional design provides the pallet truck with a wider range of layout and size adjustment capabilities. The most suitable extension direction of the intermediate connecting rod assembly can be selected according to actual loading needs, thereby optimizing the space utilization and load-bearing layout of the pallet truck. The formation of the mounting position is not limited to a specific direction but can be flexibly changed according to the assembly method of the connecting components, increasing the diversity and adaptability of the design. Since the connection between the intermediate connecting assembly and other components is detachable, this greatly simplifies the assembly and maintenance process. When it is necessary to adjust the size of the pallet truck or replace damaged components, the operator can quickly disassemble and reassemble the intermediate connecting assembly without disassembling the entire pallet truck. This design reduces maintenance costs, minimizes production downtime caused by maintenance, and improves overall operational efficiency.

[0072] The intermediate connecting rod assembly 421 and the connecting bracket assembly 422 are assembled through a detachable connection. This modular design allows for targeted replacement or adjustment of individual components during maintenance without disassembling the entire pallet truck, saving maintenance time and improving repair and maintenance efficiency. Simultaneously, this design also enables the pallet truck to be quickly adjusted according to actual needs, supporting flexible adjustments to the production line.

[0073] like Figure 5As shown, the intermediate connecting rod assembly 421 includes: a second connecting rod 4213, a second sleeve body 4212, a first overlapping rod 4211, a third sleeve body 4214, and a second overlapping rod 4215. The second connecting rod 4213 extends along a first preset direction, the second sleeve body 4212 is arranged along a second preset direction, and a second connecting end is provided on the surface of the second sleeve body 4212. The second sleeve body 4212 is detachably connected to the first end of the second connecting rod 4213 through the second connecting end. The first overlapping rod 4211 is arranged along the second preset direction and is movably connected to the second sleeve body 4212. The third sleeve body 4214 is arranged along the second preset direction. A third connecting end is provided on the surface of 4. The third sleeve body 4214 is detachably connected to the second end of the second connecting rod 4213 through the third connecting end. The second overlapping rod 4215 is arranged along the second preset direction and is movably connected to the third sleeve body 4214. Among them, the first end of the first overlapping rod 4211 and the first end of the first connecting component 41 form a first mounting position, the second end of the first overlapping rod 4211 and the first end of the second connecting component 43 form a third mounting position, the first end of the second overlapping rod 4215 and the second end of the first connecting component 41 form a second mounting position, and the second end of the second overlapping rod 4215 and the second end of the second connecting component 43 form a fourth mounting position.

[0074] In this embodiment, through connection with the second sleeve body 4212 and the third sleeve body 4214, the first and second overlapping rods can be adjusted in position in a second preset direction as needed. This adjustability allows the pallet assembly to be flexibly installed under different operating conditions. Whether it is to expand the carrying area of ​​the pallet truck or to adjust the spacing between pallet assemblies, it can be achieved through simple adjustments, improving the pallet truck's adaptability to changes in the production line. The second sleeve body 4212 and the third sleeve body 4214 not only provide connection points for the first and second overlapping rods, but also achieve detachable connection with the intermediate connecting rod through their own second and third connecting ends. This connection method allows the intermediate connecting rod assembly to be easily assembled or disassembled with the first connecting assembly 41 or the second connecting assembly 43, further enhancing the modularity of the pallet truck and facilitating rapid adjustment and maintenance on the production site. The formation of the first to fourth mounting positions is based on the connection of the first and second overlapping rods with the connecting assembly. This design allows users to freely adjust the position of the pallet assembly as needed. When not in use, the entire pallet truck can be folded into a more compact state by retracting the first and second connecting rods, saving storage space, which is especially beneficial in factory environments with limited space resources.

[0075] The intermediate connecting rod assembly 421 is designed according to standardization principles, ensuring good interchangeability with other components (such as the first connecting assembly and the second connecting assembly). This design not only simplifies the pallet truck manufacturing process but also allows for the rapid identification of replacement components when maintaining or updating the pallet truck structure, reducing maintenance time and downtime, and improving equipment availability and maintenance efficiency.

[0076] In one exemplary embodiment, such as Figure 6 As shown, the connecting bracket assembly 422 includes: a third overlapping rod 4221, a fourth overlapping rod 4223, and a fourth sleeve body 4222. The third overlapping rod 4221 is arranged along a second preset direction, and its first end is detachably connected to one of the first connecting assembly 41 and the second connecting assembly 43. The fourth overlapping rod 4223 is arranged along the second preset direction, and its first end is detachably connected to the other of the first connecting assembly 41 and the second connecting assembly 43. The fourth sleeve body... 4222 is set along the second preset direction. The surface of the third sleeve body 4214 is provided with a third connecting end and a fourth connecting end. The third connecting end and the fourth connecting end are symmetrically arranged about the axis of the fourth sleeve body 4222. The fourth sleeve body 4222 is movably connected to the second connecting rod 4213. The fourth sleeve body 4222 is detachably connected to the second end of the third overlapping rod 4221 through the third connecting end. The fourth sleeve body 4222 is detachably connected to the second end of the fourth overlapping rod 4223 through the fourth connecting end.

[0077] In this embodiment, the fourth sleeve body 4222 is arranged along the second preset direction and is movably connected to the second connecting rod 4213. This means that the connecting bracket assembly 422 can adjust its position and angle within a certain range. This flexibility allows the connecting bracket assembly to be quickly adjusted to the most suitable state under different logistics needs or cargo sizes, providing stable support for the pallet assembly. It also facilitates the modular expansion of the pallet truck to adapt to changes in the production line. The symmetrical arrangement of the third and fourth connecting ends about the axis of the fourth sleeve body 4222 not only ensures the structural balance of the connecting bracket assembly but also provides uniform support for the pallet assembly, preventing the cargo from tilting or swaying during transportation.

[0078] The connecting bracket assembly connects to the first and second connecting components via a third and fourth lap rod. This multi-point connection design ensures robustness at the joints and reduces structural instability caused by insufficient connection points. Simultaneously, the connecting bracket assembly distributes the load, improving overall load-bearing capacity and operational safety. The modular design of the connecting bracket assembly allows for targeted addition or replacement of components when adjustments to the pallet truck's size or shape are needed, without disassembling the entire pallet truck. This design also facilitates quick replacement of specific components in case of damage or wear, reducing maintenance costs and improving the pallet truck's maintainability and durability.

[0079] In one exemplary embodiment, such as Figure 7 As shown, the pallet assembly 30 includes a pallet body 31 and a pallet mat 32. At least one caster wheel 60 is located at the bottom of the pallet body 31, and the pallet mat 32 is attached to the top of the pallet body 31. The pallet mat 32, attached to the top of the pallet body 31, provides anti-slip and cushioning effects, effectively preventing slippage, collision, and damage to goods during transportation, ensuring the safety and integrity of the goods. The role of the pallet mat is particularly crucial when transporting delicate or fragile items, as it significantly reduces potential risks during transshipment. Furthermore, the design of the pallet assembly 30, through the installation of casters and the pallet mat, not only improves the mobility of the pallet truck and the stability of the goods, but also optimizes load-bearing capacity and ground adaptability. It also facilitates loading and unloading of goods, promotes cleanliness and hygiene, and enhances operational simplicity.

[0080] Furthermore, the modular assembly pallet truck also includes: a handle assembly 10, a first traction assembly 20 and a second traction assembly 50, at least a portion of the handle assembly 10 being connected to the pallet assembly 30, at least a portion of the first traction assembly 20 being connected to a first end of the connecting assembly 40, and at least a portion of the second traction assembly 50 being connected to a second end of the connecting assembly 40.

[0081] In this embodiment, by introducing handle assembly 10 and traction assembly, and enabling them to be flexibly connected with other components, the modular pallet truck achieves functional diversification and scalability. For example, by adjusting the number and position of the handle assembly, it can be adapted to workers of different body types and operating habits; by replacing the traction assembly, the pallet truck can be adapted to different traction devices or connection methods to meet logistics needs in multiple scenarios.

[0082] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below."
