As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0040] It should be noted that the terms "first", "second", etc. in the description and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order different from those illustrated or described herein. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0041] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill 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 thus their description will be omitted.

[0042] In a modern industrial logistics system, the operating efficiency of a pallet truck is one of the key factors affecting the supply chain efficiency and cost-effectiveness. Traditional pallet trucks are usually equipped with a fixed traction mechanism, such as a towing hook, for connection to a towing vehicle (such as a forklift). This design simplifies the towing process to a certain extent and ensures the safety of transportation. However, in practical applications, especially in a production environment with a high degree of automation and a fast material flow rate requirement, the limitations of the fixed traction mechanism gradually emerge, mainly reflected in the following points:

[0043] Every time of loading, unloading or material handover, manual or semi-automatic equipment needs to intervene to accurately connect the towing hook with the towing vehicle before transportation can begin. Similarly, after arriving at the destination, a cumbersome disconnection operation has to be carried out. This series of connection and disconnection processes not only consume a large amount of time but also increase the operation difficulty. Especially at night or under poor visibility conditions, the accuracy of docking will be affected, further reducing the work efficiency.

[0044] On a highly automated production line, the flow of materials needs to quickly respond to the production rhythm to maintain the continuity and high efficiency of the production line. The pallet truck with a fixed towing mechanism is not flexible enough in such an environment and cannot quickly adapt to the changes in the production line, such as a sudden increase in material demand or production line adjustment, etc. This leads to an increase in the waiting time of the production line and reduces the overall operation efficiency.

[0045] Fixed mechanisms such as towing hooks are prone to wear or damage during long-term use and need regular inspection and maintenance. In addition, different models of pallet trucks may require different towing hooks, which increases the complexity of maintenance and the types of spare parts required, indirectly raising the operating costs.

[0046] Combined with Figure 1 As shown, according to a specific embodiment of the present application, a non-wheel-mounted general-purpose mother-and-son vehicle apparatus is provided, including: a mother vehicle part 20 and a son vehicle part 10. The son vehicle part 10 includes a plurality of son vehicle parts 10. At least one of the plurality of son vehicle parts 10 is detachably connected to the mother vehicle part 20. At least one of the plurality of son vehicle parts 10 has a transportation position connected to the mother vehicle part 20, and at least one of the plurality of son vehicle parts 10 has a loading and unloading position separated from the mother vehicle part 20. The son vehicle part 10 is used for loading non-wheel goods.

[0047] Applying the technical solution of this embodiment, through the detachable connection method between the plurality of son vehicle parts 10 and a single mother vehicle part 20, the son vehicle part 10 can quickly switch between the transportation position and the loading and unloading position. Thus, when arriving at the production line, the son vehicle part 10 can quickly separate from the mother vehicle part 20 for unloading goods without individually releasing the towing hook one by one, thereby greatly reducing the empty-full exchange time, improving the continuity and efficiency of logistics operations, and solving the problem of low operation efficiency caused by repeatedly detaching and attaching the towing hook when the traditional pallet truck goes online in the prior art.

[0048] Furthermore, the non-wheel-mounted general-purpose mother-and-son vehicle apparatus further includes: a locking part 40. The execution end of the locking part 40 has an unlocking position and a locking position. The fixed end of the locking part 40 is connected to one of the son vehicle part 10 and the mother vehicle part 20. When the son vehicle part 10 is in the transportation position, the execution end is in the locking position and cooperates with the other of the son vehicle part 10 and the mother vehicle part 20.

[0049] When the actuator of the locking part 40 is in the locked position, it can effectively fix the relative position of the sub-vehicle part 10 and the mother-vehicle part 20, ensuring that the sub-vehicle part will not break away from the mother-vehicle part due to vibration or accidental collision during transportation, greatly improving the safety and stability during transportation. This is particularly important for the transportation of non-wheeled pallets or heavy goods, avoiding potential risks during the movement of goods.

[0050] When the sub-vehicle part 10 is in the transportation position, the actuator of the locking part 40 automatically moves to the locked position without the need for additional manual fixing operations by the operator. This automatic locking mechanism significantly shortens the loading and unloading time and improves the efficiency of logistics operations, especially for application scenarios where the sub-vehicle part and the mother-vehicle part are frequently exchanged, such as rapid material replenishment on the production line or material handling in large warehouses.

[0051] In an exemplary embodiment, the locking part 40 is a pneumatic telescopic device, and the pneumatic telescopic device is connected to an external air pump through a solenoid valve. The advantage of the pneumatic telescopic device lies in its fast response and high-efficiency operation. When it is necessary to fix the sub-vehicle part 10 in the transportation position, the solenoid valve is opened, and the compressed air provided by the external air pump quickly fills the pneumatic telescopic device, prompting the actuator (telescopic rod) to extend, realizing a firm lock between the sub-vehicle part and the mother-vehicle part. Conversely, when unlocking is required, the solenoid valve is closed, the gas in the pneumatic telescopic device is discharged, the actuator contracts, and the sub-vehicle part can be quickly separated. This process significantly shortens the loading and unloading time and improves the efficiency of logistics operations compared with mechanical locking or manual unlocking methods.

[0052] In this embodiment, the loadable non-wheeled universal mother-and-sub vehicle appliance further includes: a handrail 30, and the handrail 30 is selectively detachably connected to one of the sub-vehicle part 10 and the mother-vehicle part 20. The handrail 30 provides a more intuitive control point for the operator, making it easier to manually move the sub-vehicle part 10 or the mother-vehicle part 20. The detachable feature means that the operator can install the handrail according to actual needs. Whether operating the sub-vehicle part or the mother-vehicle part alone, it can ensure the best operating experience, reduce the physical burden during the operation, and improve work efficiency.

[0053] As Figure 2 shown, the mother-vehicle part 20 includes: a mother-vehicle frame assembly, a first wheel assembly, and a slideway assembly. The first wheel assembly includes a plurality of first universal wheels 202, and the plurality of first universal wheels 202 are arranged at intervals. The first fixing seats of the plurality of first universal wheels 202 are respectively connected to the mother-vehicle frame assembly, and the slideway assembly is connected to the top of the mother-vehicle frame assembly. When the sub-vehicle part 10 is in the transportation position, the slideway assembly cooperates with the sub-vehicle part 10.

[0054] The first wheel assembly utilizes multiple, spaced-apart first universal wheels 202, allowing the carrier portion 20 to move freely in all directions, without requiring the vehicle body to be rotated. This is particularly important for transporting cargo in confined or complex industrial environments, effectively improving the vehicle's flexibility and maneuverability while reducing operating time and labor.

[0055] The arrangement of multiple first universal wheels 202 not only distributes the load and reduces the pressure on the ground, but also provides better balance. Even on non-homogeneous ground or uneven terrain, it can maintain a stable operating state and reduce the risk of overturning due to heavy cargo.

[0056] Furthermore, the mother frame assembly includes: a first mother frame connecting section 203, a second mother frame connecting section 207 and an intermediate connecting section 208, the second mother frame connecting section 207 is spaced apart from the first mother frame connecting section 203, and the first mother frame connecting section 203 and the second mother frame connecting section 207 are connected by the intermediate connecting section 208.

[0057] The spacing between the first and second mother-frame connecting sections 203 and 207, and the connection between the intermediate connecting sections 208, form a stable frame structure. This design effectively disperses stress when carrying loads, improving the overall strength and stability of the structure and reducing the risk of deformation or damage, particularly when transporting heavy objects.

[0058] In this embodiment, the mother frame assembly further includes a drawbar 201, the first end of which is selectively and movably connected to either the first or second end of the mother frame assembly. This allows the drawbar's connection location to be selected based on practical needs. In different logistics operating environments, operators can flexibly select the drawbar connection point based on spatial layout, loading requirements, or operational habits, for optimal control and convenience.

[0059] In an exemplary embodiment, the slide assembly includes: a first slide 204 and a second slide 205, at least a portion of the base of the first slide 204 is connected to the top of the mother frame assembly, the second slide 205 is set at a distance from the first slide 204, and at least a portion of the base of the second slide 205 is connected to the top of the mother frame assembly.

[0060] The arrangement of the first and second slides 204 and 205 provides a clear guide path for the sub-carriage 10, ensuring accurate positioning of the sub-carriage when loading and unloading from the mother carriage, reducing operational errors and improving loading and unloading efficiency. The dual slides provide a smoother sliding motion for the sub-carriage, avoiding lateral deviation or shaking caused by the unstable guidance of a single slide.

[0061] Further, the first wheel assembly further includes: an auxiliary wheel 206. There is at least one auxiliary wheel 206, which is disposed between two adjacent first universal wheels 202, and the second fixing seat of at least a part of the auxiliary wheel 206 is connected to the mother frame assembly.

[0062] The addition of the auxiliary wheel 206, especially between two adjacent first universal wheels 202, increases the contact points with the ground, effectively disperses the load, and improves the overall stability. When carrying heavy or irregular loads, this multi-point support design can ensure the balanced distribution of the load, avoid rollover or instability caused by excessive force on a single point, and enhance the balance and safety during transportation.

[0063] The connection between the auxiliary wheel 206 and the mother frame assembly enables the auxiliary wheel to move flexibly along with the first universal wheel 202 when it steers or adjusts, maintaining contact with the ground, thereby improving the mobility and flexibility of the mother vehicle part 20 in complex terrains or narrow spaces. This design makes the equipment move more smoothly when turning, bypassing obstacles, or making multi-directional movements, reducing the operation difficulty and time consumption.

[0064] In an exemplary embodiment, two auxiliary wheels 206 are disposed between the first slideway 204 and the second slideway 205. When the sub-vehicle part 10 moves along the first slideway 204 and the second slideway 205, the auxiliary wheels 206 located between the two slideways can provide additional lateral support, effectively preventing lateral swing or tilting of the sub-vehicle part during the sliding process. Especially when transporting heavy or irregularly shaped goods, this improvement in stability is particularly crucial to ensure the safety of the goods.

[0065] As Figure 3 and Figure 4 shown, the sub-vehicle part 10 includes: a sub-frame assembly and a second wheel assembly. The second wheel assembly includes a plurality of second universal wheels 103, which are spaced apart, and the second fixing seats of the plurality of second universal wheels 103 are respectively connected to the sub-frame assembly.

[0066] The use of the second universal wheels 103 provides the sub-vehicle part 10 with omnidirectional steering ability. The characteristics of the universal wheels allow the sub-vehicle part to move easily in any direction, which is particularly important in narrow spaces or complex logistics environments, improving the mobility and operation efficiency of the equipment and reducing the operation difficulty.

[0067] The plurality of second universal wheels 103 are spaced apart to ensure the uniform distribution of the load on the sub-vehicle part. This design avoids instability caused by concentrated load at a certain point, reduces the risk of wheel damage due to overload, and improves the load-bearing capacity and durability of the equipment.

[0068] Further, the sub-frame assembly includes: a sub-frame support plate 102 and a limiting plate 101. The sub-frame support plate 102 extends along a first preset direction. The limiting plate 101 extends along one of the length direction and the width direction of the sub-frame support plate 102. There are multiple limiting plates 101, and the multiple limiting plates 101 are arranged at intervals. The multiple limiting plates 101 are detachably connected to the top of the sub-frame support plate 102.

[0069] The spaced arrangement of the limiting plates 101 provides effective physical restraint for the goods placed on the sub-frame support plate 102, preventing the goods from moving or falling due to inertia or external impact during transportation, and ensuring the safety of the goods. This is particularly important for transporting fragile items, precision instruments or high-value goods, reducing losses and risks during the logistics process.

[0070] The design of the detachable connection between the limiting plate 101 and the top of the sub-frame support plate 102 enables the limiting plate to be freely adjusted and replaced according to the size and shape of different goods, improving the flexibility and versatility of the sub-vehicle part 10. This modular design enables the equipment to adapt to diverse logistics requirements, reduces the purchase of dedicated equipment, and lowers the logistics cost.

[0071] In an exemplary embodiment, a limiting hole 104 is provided on the sub-frame support plate 102. When the execution end of the locking portion 40 is in the locking position, at least a part of the execution end cooperates with the limiting hole 104. The cooperation of the limiting hole and the execution end can accurately position and lock the sub-vehicle part 10 during the loading and unloading process, preventing the sub-vehicle part from shifting or falling off due to inertia or external impact during transportation, and significantly improving the safety and reliability of the equipment. Especially under high-speed driving or complex road conditions, this locking mechanism is crucial for ensuring the safety of goods and operators.
