Description

Technical Field

[0001] This application relates to the field of transfer vehicle technology, and more particularly to a shared bicycle transfer vehicle. Background Technology

[0002] The large-scale operation of shared bicycles relies on an efficient vehicle dispatching system. Currently, the dispatching of shared bicycles is generally carried out manually. Dispatchers need to carry the scattered shared bicycles one by one onto the truck bed, which is labor-intensive, inefficient, and prone to collisions and damage between bicycles during dense stacking.

[0003] To improve scheduling efficiency, existing technologies attempt to use dedicated loading units to carry individual vehicles and employ mechanical mechanisms to transfer these units inside and outside the vehicle compartment. However, in practical applications, the lack of a unified and reliable interface design between the loading units and the vehicle compartment leads to positional deviations during the loading unit's entry and exit, resulting in poor docking or even jamming, thus affecting the continuity and reliability of scheduling operations. Furthermore, the existing solutions have a single flow path for the loading units, making it difficult to flexibly adapt to varying numbers of vehicles. When multiple loading units need to be processed simultaneously, manual intervention for position adjustment and alignment is often required, failing to fully leverage the advantages of mechanized operations.

[0004] Therefore, how to achieve efficient and reliable docking and transfer between loading units and carriages, so that multiple loading units can complete loading and storage in an orderly and stable manner, has become a core technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] In view of this, this application proposes a shared bicycle transfer vehicle to solve the technical problems of insufficient docking stability between loading units and carriages and low turnover efficiency of multiple loading units in the prior art.

[0006] The technical solution of this application is implemented as follows: This application provides a shared bicycle transfer vehicle, including: The carriage has at least one storage platform arranged vertically inside it; At least two trays are arranged horizontally on the storage platform to support shared bicycles; The lifting tailgate assembly is located on the outer side of the rear of the vehicle body. The lifting tailgate assembly has a guide and positioning structure that enables multiple trays removed from the vehicle body to be stacked sequentially in the vertical direction on the lifting tailgate assembly and kept in position. A horizontal transfer mechanism is used to drive the pallet to move horizontally between the storage platform and the lifting tail plate assembly; The lifting mechanism, located at the rear of the carriage, is used to drive the lifting tailgate assembly to lift and lower so that any pallet is level with the corresponding storage platform inside the carriage.

[0007] Based on the above technical solution, preferably, the lifting tailgate assembly includes a tailgate frame, and the tailgate frame is provided with the guide positioning structure on at least one side perpendicular to the pallet moving direction. The guide positioning structure includes a plurality of guide grooves that are distributed vertically at intervals and extend along the pallet moving direction. The pallet is provided with guide wheels that cooperate with the guide grooves. The guide wheels are embedded in the corresponding guide grooves to limit the horizontal displacement of the pallet in the direction perpendicular to its moving direction.

[0008] Based on the above technical solution, preferably, the lifting tailgate assembly further includes a first locking mechanism disposed on the tailgate frame. The first locking mechanism is used to lock the tray after the tray moves to a predetermined position on the tailgate frame, so as to limit the displacement of the tray relative to the tailgate frame along its moving direction.

[0009] Based on the above technical solution, preferably, the first locking mechanism includes a fixed base, a first stop member, and a first driving member; The fixing seat is located at the end of the tailgate frame away from the carriage, and the end of the tailgate frame away from the carriage is provided with a blocking member. The first stop is movably disposed on the fixed seat along the extension direction perpendicular to the guide groove; the first drive is used to drive the first stop to move relative to the fixed seat to the blocking position or retract. The first stop is configured such that when the pallet moves to the end point and is blocked by the blocking member, the first stop moves to the blocking position under the action of the first driving member to block the guide wheel on the side away from the blocking member, so as to restrict the pallet from falling out in the opposite direction of its movement.

[0010] Based on the above technical solution, preferably, the pallet is provided with traveling wheels on both sides along its moving direction, the axis of the traveling wheels is perpendicular to the axis of the guide wheels, the traveling wheels are in rolling contact with the bottom surface of the guide groove, and the vertical distance between the lowest point of the traveling wheels and the top surface of the pallet is greater than the vertical distance between the lowest point of the guide wheels and the top surface of the pallet.

[0011] Based on the above technical solution, preferably, the pallet includes a pallet frame, and wheel limiting structures are provided on both sides of the pallet frame perpendicular to its direction of movement. The wheel limiting structures are used to limit the wheels of the single vehicle. A front stop bar is hinged to the front of the pallet frame. The front stop bar can be rotated to a retracted position flush with the upper plane of the pallet frame or to an upright blocking position. A rear stop bar is provided at the rear of the pallet frame. The rear stop bar is an insertable structure that can be selectively inserted into a fixing groove provided on the pallet frame.

[0012] Based on the above technical solution, preferably, guide rails are fixedly provided on both sides of the storage platform along the direction perpendicular to the pallet movement, and the guide rails are used to guide the guide wheel into the guide rail; The horizontal transfer mechanism includes a linear module and an actuator. The linear module is disposed on the side wall of the carriage and is used to drive the actuator to move horizontally. The actuator is used to connect with the pallet to drive the pallet to move horizontally between the storage platform and the lifting tailgate assembly.

[0013] Based on the above technical solution, preferably, the guide rail is provided with a plurality of retractable positioning pins at intervals along its length, the positioning pins being used to limit the position of the tray located on the storage platform.

[0014] Based on the above technical solution, preferably, the actuator includes a connecting rod and a second locking mechanism. One end of the connecting rod is fixedly connected to the drive end of the linear module, and the other end is connected to the second locking mechanism, which is used to lock the connection with the tray.

[0015] Based on the above technical solution, preferably, the second locking mechanism includes a mounting base, a second stop, and a second driving member. The mounting base is fixedly disposed at the end of the connecting rod, and the second driving member is used to drive the second stop to move relative to the mounting base in a vertical direction. The tray is provided with a mating part that cooperates with the second stop. The second stop and the mating part are locked together to realize the locking connection between the actuator and the tray.

[0016] This application has the following advantages over the prior art: 1) This application ensures the positional accuracy of pallets during entry and exit through the guiding and positioning structure of the lifting tailgate assembly, avoiding docking misalignment and jamming, and improving the stability and reliability of docking between the loading unit and the truck bed. Multiple pallets are stacked sequentially along the vertical direction on the lifting tailgate assembly, allowing the lifting mechanism to serve the loading operation of multiple pallets in one lifting stroke, significantly improving the turnover efficiency of multiple loading units. The entire loading process is mechanized through the coordinated operation of the horizontal transfer mechanism and the lifting mechanism, eliminating the need for manual position adjustment and alignment, reducing labor intensity, and avoiding collision damage to single vehicles during dense stacking. Therefore, this invention effectively solves the technical problems of insufficient docking stability between loading units and truck beds and low turnover efficiency of multiple loading units in the prior art, and has the beneficial effects of high loading efficiency, low labor intensity, good protection of single vehicles, and high system reliability.

[0017] 2) By incorporating a guide and positioning structure on the tailgate frame and designing a matching structure for the pallets, the guide and positioning structure provides precise guidance and limits during the pallet's entry and exit from the lifting tailgate assembly. This ensures the pallet's horizontal positioning accuracy and prevents collisions or jamming between the pallet and the tailgate frame or other pallets. This lays a reliable positioning foundation for subsequent vertical pallet stacking and docking operations when pallets are moved from the lifting tailgate assembly into the storage platform. Simultaneously, the design of multiple guide slots spaced vertically allows multiple pallets to be stacked sequentially on the lifting tailgate assembly and maintain their individual positions, effectively improving the stability and reliability of multi-pallet loading operations.

[0018] 3) Through the locking action of the first locking mechanism, the pallet is reliably fixed on the tail plate frame and will not slide or fall off in the direction of movement due to gravity or vibration during the lifting process. This ensures the safety of subsequent vertical stacking and the lifting mechanism driving the tail plate assembly to lift as a whole, and ensures the positional accuracy of the pallet when docking with the storage platform.

[0019] 4) By installing front and rear stop bars on the front and rear sides of the pallet respectively, these two elements form obstructions at both ends of the bicycle, working together with the wheel limiting structures on both sides to create all-around restraint for the bicycle. The wheel limiting structures restrict the lateral movement of the wheels, the front stop bars restrict the forward movement of the bicycle, and the rear stop bars restrict the backward movement of the bicycle. Together, these three elements ensure that the bicycle is reliably fixed to the pallet during transportation, preventing any directional movement. Furthermore, the hinged design of the front stop bars and the insertable design of the rear stop bars allow both to be folded up or removed when pallets need to be stacked, keeping the pallet surface flat and facilitating the vertical stacking of multiple pallets.

[0020] 5) A single linear module and an actuator can complete the transfer operation of all pallets, eliminating the need for an independent drive mechanism for each pallet. This significantly simplifies the system structure and reduces manufacturing costs and maintenance difficulty. Furthermore, the connecting rod allows the linear module to be positioned on the side wall of the carriage, while the second locking mechanism can extend to the pallet location, achieving spatial separation between the power source and the actuator, facilitating a more rational layout within the carriage.

[0028] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0029] like Figure 1 As shown, combined with Figure 2-15 This application discloses a shared bicycle transfer vehicle, which includes a carriage 1, at least two trays 2, a lifting tailgate assembly 3, a horizontal transfer mechanism 4, and a lifting mechanism 5.

[0030] The carriage 1 is the main structure of the vehicle, used to accommodate and transport shared bicycles P. In this embodiment, the shared bicycle P applicable to the transfer vehicle can be either a shared bicycle or a shared electric bicycle.

[0031] The interior of the carriage 1 has at least one storage platform 11 arranged vertically, which provides horizontal support and placement space for the pallet 2. In this embodiment, the number of storage platforms 11 can be one, or two or more, depending on actual needs, to meet different loading requirements. To more clearly illustrate the usage scenario of the transfer vehicle of this application, the accompanying drawings provided in this example illustrate a two-layer structure.

[0032] At least two pallets 2 are horizontally arranged on the storage platform 11, each pallet 2 being used to carry shared bicycles P. As the carrying unit for the shared bicycles P, the pallets 2 allow the shared bicycles P to be neatly arranged in a modular manner inside the carriage 1, avoiding collisions and squeezing between the bicycles. The horizontal arrangement of the pallets 2 on the storage platform 11 allows multiple pallets 2 to be stored simultaneously in the carriage 1, providing a foundation for subsequent mechanized loading.

[0033] The lifting tailgate assembly 3 is located on the outer side of the rear of the carriage 1. This assembly has a guide and positioning structure 32. The guide and positioning structure 32 enables multiple pallets 2 removed from the carriage 1 to be stacked vertically on the lifting tailgate assembly 3 and held in position. As the first pallet 2 is moved from the carriage 1 to the lifting tailgate assembly 3, the guide and positioning structure 32 provides precise guidance and positioning, keeping it in a predetermined position. Subsequently, the second pallet 2 is moved from the carriage 1 and stacked on top of the first pallet 2, also precisely positioned by the guide and positioning structure 32. This process is repeated, allowing multiple pallets 2 to form a stable vertical stack on the lifting tailgate assembly 3. This stacking method allows multiple pallets 2 to share the lifting stroke of the lifting tailgate assembly 3, eliminating the need for individual lifting operations for each pallet 2, thus significantly improving loading efficiency.

[0034] The horizontal transfer mechanism 4 drives the pallet 2 to move horizontally between the storage platform 11 and the lifting tail assembly 3. When a shared bicycle P needs to be loaded, the horizontal transfer mechanism 4 moves the pallet 2 from the storage platform 11 inside the vehicle compartment 1 to the lifting tail assembly 3 at the rear of the vehicle compartment 1. After the pallet 2 has finished loading the bicycle, the horizontal transfer mechanism 4 moves the pallet 2 back from the lifting tail assembly 3 to the storage platform 11 inside the vehicle compartment 1. The horizontal transfer mechanism 4 realizes the bidirectional transfer of the pallet 2 between the inside and outside of the vehicle compartment 1 and is a key transmission link in the entire loading process.

[0035] A lifting mechanism 5 is located at the rear of the carriage 1 and is used to drive the lifting tailgate assembly 3 to rise and fall vertically. Driven by the lifting mechanism 5, the lifting tailgate assembly 3 can raise or lower multiple pallets 2 stacked on it as a whole, so that any pallet 2 is aligned with the corresponding storage platform 11 inside the carriage 1. For example, after the top pallet 2 has been loaded onto a single vehicle, the lifting mechanism 5 drives the lifting tailgate assembly 3 to rise, making the pallet 2 aligned with the storage platform 11. Then, the horizontal transfer mechanism 4 pulls the pallet 2 into the carriage 1. Next, the lifting mechanism 5 again drives the lifting tailgate assembly 3 to descend to the ground to facilitate loading the next layer of pallets 2 onto a single vehicle. This cycle continues until all pallets 2 have been loaded and stored in the carriage 1.

[0036] Through the coordination of the above structures, this invention achieves efficient and automated scheduling of shared bicycles P. The specific workflow is as follows: In the initial state, multiple trays 2 are horizontally arranged on the storage platform 11 inside the carriage 1. During loading, the horizontal transfer mechanism 4 moves the first tray 2 from the storage platform 11 onto the lifting tail plate assembly 3, where the guide positioning structure 32 of the lifting tail plate assembly 3 precisely positions the tray 2. Subsequently, the horizontal transfer mechanism 4 moves the second tray 2 out and stacks it on top of the first tray 2, again achieving positioning through the guide positioning structure 32. The above steps are repeated until all trays 2 are stacked on the lifting tail plate assembly 3. Next, the lifting mechanism 5 drives the lifting tail plate assembly 3 to descend to the ground, and the dispatcher pushes the shared bicycle P onto the top tray 2 and secures it. After loading is complete, the lifting mechanism 5 drives the lifting tail plate assembly 3 to rise, making the top tray 2 level with the storage platform 11 inside the carriage 1, and the horizontal transfer mechanism 4 pulls the tray 2 back into the carriage 1. Subsequently, the lifting mechanism 5 drives the lifting tailgate assembly 3 to descend to the ground again to load the next layer of pallets 2 onto a single vehicle. The above steps are repeated until all pallets 2 are loaded and stored in the vehicle compartment 1.

[0037] This application ensures the positional accuracy of the pallet 2 during entry and exit through the guiding and positioning structure 32 of the lifting tail plate assembly 3, avoiding docking misalignment and jamming, and improving the stability and reliability of the docking between the loading unit and the carriage 1. Multiple pallets 2 are stacked sequentially along the vertical direction on the lifting tail plate assembly 3, so that one lifting stroke of the lifting mechanism 5 can serve the loading operation of multiple pallets 2, significantly improving the turnover efficiency of multiple loading units. The entire loading process is mechanized through the coordinated operation of the horizontal transfer mechanism 4 and the lifting mechanism 5, eliminating the need for manual position adjustment and alignment, reducing labor intensity, and avoiding collision damage to single vehicles during dense stacking. Therefore, this invention effectively solves the technical problems of insufficient docking stability between the loading unit and the carriage 1 and low turnover efficiency of multiple loading units in the prior art, and has the beneficial effects of high loading efficiency, low labor intensity, good single vehicle protection, and high system reliability.

[0038] In some embodiments, refer to the appendix Figure 7 and 8 As shown, the lifting tailgate assembly 3 includes a tailgate frame 31, which is the main support structure of the lifting tailgate assembly 3 and provides a foundation for the installation of other components. At least one side of the tailgate frame 31 perpendicular to the moving direction of the pallet 2 is provided with a guide and positioning structure 32. This guide and positioning structure 32 is used to guide and position the pallet 2 when it enters and exits the lifting tailgate assembly 3, ensuring the horizontal positional accuracy of the pallet 2.

[0039] The guiding and positioning structure 32 includes multiple guide grooves 321 that are vertically spaced and extend along the moving direction of the pallet 2. The vertically spaced guide grooves 321 ensure that each pallet 2 has a corresponding guide groove 321 to engage with during stacking, thereby achieving precise stacking of multiple pallets 2 in the vertical direction. The extension of the guide grooves 321 along the moving direction of the pallet 2 allows the pallet 2 to move along a predetermined path during entry and exit, preventing deviation from its orientation.

[0040] The pallet 2 is equipped with guide wheels 22 that mate with guide grooves 321, with the guide wheels 22 embedded within the corresponding guide grooves 321. When the pallet 2 is moved from the carriage 1 to the lifting tailgate assembly 3, the guide wheels 22 roll along the guide grooves 321, guiding the pallet 2 smoothly into the predetermined position. Because the guide wheels 22 are embedded in the guide grooves 321, the side walls of the guide grooves 321 limit the guide wheels 22, thereby restricting the horizontal displacement of the pallet 2 perpendicular to its direction of movement. This means that the pallet 2 will not deviate left or right during entry and exit, and will always maintain a straight line movement consistent with the direction of movement.

[0041] It is worth noting that the guide positioning structure 32 is disposed on at least one side of the tailboard frame 31 perpendicular to the moving direction of the pallet 2. When the guide positioning structure 32 is disposed on only one side of the tailboard frame 31, the guide groove 321 on that side cooperates with the guide wheel 22 on the corresponding side of the pallet 2 to provide unilateral guide and limit for the pallet 2. Since the guide wheel 22 is embedded in the guide groove 321, the side wall of the guide groove 321 limits the guide wheel 22, preventing the pallet 2 from undergoing horizontal displacement perpendicular to the moving direction on that side. Driven by the horizontal transfer mechanism 4, the pallet 2 moves along a straight path. Under the action of unilateral guide and limit, the pallet 2 maintains a straight movement consistent with the moving direction and will not deflect or run off course. After the first pallet 2 moves to the predetermined position, the pallet 2 stops on the tailboard frame 31. Subsequently, the second pallet 2 is removed from the carriage 1, moves along a straight path through the unilateral guide positioning structure 32, and is stacked on top of the first pallet 2. At this time, the upper surface of the lower pallet 2 provides vertical support for the upper pallet 2, allowing the upper pallet 2 to be stably placed on top of the lower pallet 2. Through the support of the lower pallet 2 and the guiding and limiting action of the guide wheels 22 of the upper pallet 2, multiple pallets 2 form a stable vertical stack on the tail plate frame 31. This single-sided guiding and positioning structure 32 simplifies the structure and reduces costs while ensuring the accuracy of pallet 2 entry, exit, and stacking.

[0042] Of course, guide positioning structures 32 can also be set on both sides of the tail plate frame 31 to provide symmetrical guide and limit on both sides, further improving the positioning accuracy and stability of the pallet 2.

[0043] Of course, guide positioning structures 32 can also be provided on both sides of the tail plate frame 31 to form an integral guide groove, and guide wheels 22 can be provided on both sides of the pallet 2 to guide the pallet 2 as a whole. Through the above structure, the guide positioning structure 32 provides precise guidance and limit during the process of the pallet 2 entering and exiting the lifting tail plate assembly 3, ensuring the horizontal positional accuracy of the pallet 2, avoiding collisions or jamming between the pallet 2 and the tail plate frame 31 or other pallets 2, and laying a reliable positioning foundation for the subsequent vertical stacking of the pallets 2 and the docking operation when the pallet 2 is moved from the lifting tail plate assembly 3 into the storage platform 11. At the same time, the design of multiple guide grooves 321 distributed vertically at intervals allows multiple pallets 2 to be stacked sequentially on the lifting tail plate assembly 3 and maintain their respective positions, effectively improving the stability and reliability of multi-pallet 2 loading operations.

[0044] In some embodiments, the lifting tailgate assembly 3 further includes a first locking mechanism 33 disposed on the tailgate frame 31. The first locking mechanism 33 is used to lock the tray 2 after the tray 2 moves to a predetermined position on the tailgate frame 31, so as to limit the displacement of the tray 2 relative to the tailgate frame 31 in its direction of movement.

[0045] Specifically, when the pallet 2 is moved out of the carriage 1 and to a predetermined position on the tailgate frame 31 under the drive of the horizontal transfer mechanism 4, this predetermined position is the final resting position of the pallet 2 on the tailgate frame 31 after stacking. At this time, the first locking mechanism 33 is activated to lock the pallet 2 on the tailgate frame 31, so that the pallet 2 cannot be displaced relative to the tailgate frame 31 in its direction of movement.

[0046] The first locking mechanism 33 and the guide positioning structure 32 are functionally complementary. The guide positioning structure 32, through the cooperation of the guide groove 321 and the guide wheel 22, restricts the horizontal displacement of the pallet 2 in the direction perpendicular to its movement, thus solving the problem of the pallet 2 shifting left and right. The first locking mechanism 33 restricts the displacement of the pallet 2 along its movement direction, thus solving the problem of the pallet 2 sliding forward and backward. Together, they achieve all-round spatial constraint on the pallet 2 on the tail plate frame 31.

[0047] Through the locking action of the first locking mechanism 33, the tray 2 is reliably fixed on the tail plate frame 31, and will not slide or fall off in the direction of movement due to gravity or vibration during the lifting process. This ensures the safety of subsequent vertical stacking and the lifting mechanism 5 driving the tail plate assembly to lift as a whole, and ensures the positional accuracy of the tray 2 when docking with the storage platform 11.

[0048] In some embodiments, the first locking mechanism 33 can be an electromagnet structure. Specifically, the first locking mechanism can be fixedly installed at the end of the tail plate frame 31 away from the carriage. When the tray moves to the end point on the tail plate frame 31, it can be blocked by the electromagnet. At the same time, after the electromagnet is activated, it can magnetically attract the tray, thereby limiting the displacement of the tray 2 along its moving direction.

[0049] In other embodiments, refer to the appendix. Figure 8 and 9 As shown in the figure, this application illustrates one structural configuration of the first locking mechanism 33. Specifically, the first locking mechanism 33 includes a fixed base 331, a first stop 332, and a first drive member 333.

[0050] The fixed base 331 is located at the end of the tailgate frame 31 away from the carriage 1, providing a mounting base for the first stop 332 and the first drive component 333. A blocking component 311 is also provided at the end of the tailgate frame 31 away from the carriage 1. The blocking component 311 is used to mechanically limit the movement endpoint of the pallet 2. When the pallet 2 moves to the endpoint, the front end of the pallet 2 contacts the blocking component 311, preventing the pallet 2 from moving forward further.

[0051] The first stop 332 is movably mounted on the fixed base 331 along a direction perpendicular to the extension of the guide groove 321. The guide groove 321 extends along the moving direction of the tray 2, therefore the direction perpendicular to the extension of the guide groove 321 is the horizontal direction perpendicular to the moving direction of the tray 2. The first stop 332 can move relative to the fixed base 331 in this direction, extending to a blocking position or retracting to a non-blocking position. The first drive member 333 is used to drive the first stop 332 to move relative to the fixed base 331 to the blocking position or retract, providing driving force for the movement of the first stop 332.

[0052] The first stop 332 is configured such that when the pallet 2 moves to the end point and is blocked by the blocking member 311, the first stop 332 moves to the blocking position under the force of the first drive member 333, blocking the side of the guide wheel 22 away from the blocking member 311. Since the guide wheel 22 is fixedly mounted on the pallet 2, the blocking of the guide wheel 22 by the first stop 332 is equivalent to the blocking of the pallet 2, thereby restricting the pallet 2 from detaching from the tail plate frame 31 in the opposite direction of its movement.

[0053] In some embodiments, the first stop 332 can be configured as a limiting roller, which can move back and forth relative to the fixed base 331. By configuring the first stop 332 as a roller structure, the guide wheel can smoothly pass over the first stop 332 during the operation with the guide wheel 22, reducing frictional resistance.

[0054] In some other embodiments, the first stop 332 may be configured as a stop pin structure, with the end of the stop pin away from the fixed seat 331 having an arc-shaped structure. This allows the guide wheel to smoothly pass over the first stop 332, reducing frictional resistance.

[0055] The first driving component 333 can be implemented in various ways.

[0056] In one implementation, the first driving member 333 is an elastic element, such as a compression spring. The elastic element is disposed within the fixed base 331 and continuously applies a restoring force to the first stop 332, pointing towards the blocking position. When the pallet 2 moves from the carriage 1 towards the tailgate frame 31, the guide wheel 22 first contacts the first stop 332 and pushes the first stop 332 to retract against the restoring force of the elastic element, allowing the pallet 2 to continue moving forward. When the pallet 2 reaches its endpoint and is blocked by the blocking member 311, the guide wheel 22 passes the position of the first stop 332. Under the action of the restoring force of the elastic element, the first stop 332 automatically pops out to the blocking position, blocking the side of the guide wheel 22 away from the blocking member 311. At this time, the pallet 2 cannot move in the opposite direction because the guide wheel 22 is stuck by the first stop 332. When it is necessary to move the pallet 2 from the tail frame 31 back to the carriage 1, a sufficiently large reverse traction force needs to be applied so that the guide wheel 22 pushes the first stop 332 again to overcome the elastic restoring force and retract, thereby removing the obstruction.

[0057] In another implementation, the first driving component 333 is an electric push rod. The telescopic end of the electric push rod is connected to the first stop 332, and the extension and retraction of the first stop 332 are achieved by electric control. When the tray 2 moves to the end point and is blocked by the blocking member 311, the control system issues a command, the electric push rod extends, and pushes the first stop 332 to the blocking position. When it is necessary to release the blockage, the electric push rod retracts, causing the first stop 332 to retract. This implementation can achieve active control without relying on the tray 2 to push the first stop 332.

[0058] In another implementation, the first driving component 333 is a push-pull quick-release clamp. The push-pull quick-release clamp is connected to the fixed base 331. Manually turning a wrench on the clamp drives a telescopic push rod, which in turn moves the first stop 332 along a direction perpendicular to the guide groove 321. The operator can manually adjust the position of the first stop 332 by turning the clamp handle, thus achieving blocking or retraction. This implementation is simple in structure, low in cost, and suitable for manual operation scenarios.

[0059] With the above structure, when the pallet 2 is blocked by the blocking member 311 after moving to the end point, the first locking mechanism 33 effectively restricts the pallet 2 from detaching in the reverse direction of its movement by utilizing the blocking effect of the first stop member 332 on the guide wheel 22, thus ensuring the positional stability of the pallet 2 on the tail plate frame 31. Meanwhile, the multiple implementations of the first driving member 333 provide flexible choices for different application scenarios, meeting the different needs of automated control and manual operation.

[0060] In some embodiments, the blocking member 311 may be a baffle, a baffle strip, a baffle tube, or other component that can block the position of the tray.

[0061] In some embodiments, the pallet 2 is provided with wheels 23 on both sides along its direction of movement. The wheels 23 are used to contact the inner bottom surface of the guide groove 321 when the pallet 2 moves, providing rolling support for the pallet 2 and reducing the frictional resistance when the pallet 2 moves. The wheels 23 are provided on both sides of the pallet 2 so that the force on both sides of the pallet 2 is even during movement, maintaining balance.

[0062] The axis of the traveling wheel 23 is perpendicular to the axis of the guide wheel 22. The axis of the guide wheel 22 is vertically aligned, allowing it to roll on the inner wall of the guide groove 321, thus providing guidance and limiting. The axis of the traveling wheel 23 is horizontally aligned, allowing it to roll on the inner bottom surface of the guide groove 321, thus providing support and load-bearing function. The perpendicularity of their axes means that the traveling wheel 23 and the guide wheel 22 do not interfere with each other functionally, each undertaking a different task.

[0063] The vertical distance between the lowest point of the traveling wheel 23 and the top surface of the pallet 2 is greater than the vertical distance between the lowest point of the guide wheel 22 and the top surface of the pallet 2. Because the lowest point of the traveling wheel 23 is lower, when the pallet 2 and the guide positioning structure 32 engage horizontally, the traveling wheel 23 first contacts the inner bottom surface of the guide groove 321, bearing the weight of the pallet 2 and providing rolling support. The guide wheel 22, due to its higher lowest point, does not contact the inner bottom surface of the guide groove 321, but only the inner sidewall of the guide groove 321, thus playing a guiding and limiting role.

[0064] Through the aforementioned height difference, the traveling wheel 23 and the guide wheel 22 establish a clear functional division. The traveling wheel 23 is responsible for supporting the weight of the pallet 2 and rolling on the inner bottom surface of the guide groove 321, enabling the pallet 2 to move smoothly. The guide wheel 22 is responsible for engaging with the inner wall of the guide groove 321, limiting the horizontal displacement of the pallet 2 perpendicular to the direction of movement, without bearing the weight of the pallet 2. This division of labor avoids the problem of accelerated wear or jamming caused by the guide wheel 22 bearing both supporting and guiding forces simultaneously, thus improving the operational stability and service life of the system. At the same time, the traveling wheel 23 and the guide wheel 22 each focus on their own function, making the pallet 2 move more smoothly and reliably in and out of the guide groove 321.

[0065] In some embodiments, refer to the appendix Figure 10-12As shown, the pallet 2 includes a pallet frame 21, which is the main structure of the pallet 2 and provides a foundation for the installation of other components. Wheel limiting structures 211 are provided on both sides of the pallet frame 21 perpendicular to its direction of movement. These wheel limiting structures 211 are used to limit the wheels of bicycles. After a bicycle is placed in the pallet frame 21, the bicycle's axis is perpendicular to the direction of movement of the pallet 2, meaning the bicycle is placed laterally on the pallet 2. In this way, multiple bicycles can be arranged sequentially along the direction of movement of the pallet 2, making full use of the length of the pallet 2 and increasing the loading density of bicycles. Simultaneously, the wheel limiting structures 211, located on both sides perpendicular to the direction of movement of the pallet 2, correspond precisely to the left and right sides of the front and rear wheels of the bicycle, effectively limiting the wheels laterally and ensuring that the bicycle is stably placed within the pallet 2, preventing lateral swaying due to vehicle vibration or turning.

[0066] As one implementation, the wheel limiting structure 211 can be configured as a recessed portion. After the bicycle is placed on the pallet frame 21, the front and rear wheels of the bicycle are located within the two recessed portions, which can prevent the shared bicycle from moving beyond the direction of movement of the pallet.

[0067] As some other implementation methods, see the appendix. Figure 13 As shown, the wheel limiting structure 211 can be set as a flip stop. In the initial state, the flip stop can be embedded in the groove on the upper surface of the pallet frame 21 through a flipping operation. When the pallet 2 needs to be loaded with shared bicycles, the flip stop is flipped out from the surface of the pallet 2, so that the flip stop is tilted at a certain angle relative to the upper surface of the pallet frame 21. In this way, after the bicycle is placed on the pallet frame 21, the front and rear wheels of the bicycle can be positioned by the flip stop, thereby preventing the shared bicycle from moving too perpendicular to the direction of pallet movement.

[0068] A front stop lever 24 is hinged to the front of the pallet frame 21. The front stop lever 24 can be rotated to either a retracted position flush with the upper surface of the pallet frame 21 or an upright blocking position. Since the bicycles are placed laterally, the front stop lever 24 is located in front of the front wheels of all bicycles. When upright, it can simultaneously block the front of multiple bicycles, preventing them from sliding forward off the pallet 2 due to inertia or vibration during transport. When the pallets 2 need to be stacked, the front stop lever 24 is rotated to the retracted position, where it is flush with the upper surface of the pallet frame 21, preventing interference with the placement of the upper pallet 2 and allowing multiple pallets 2 to be stacked tightly.

[0069] A rear stop bar 25 is provided at the rear of the pallet frame 21. The rear stop bar 25 is an insertable structure that can be selectively inserted into a fixing slot 212 provided on the pallet frame 21. The rear stop bar 25 is located at the rear of all bicycles. After being inserted into the fixing slot 212, it can block the rear of multiple bicycles and prevent them from sliding backward off the pallet 2 during transportation. When the pallets 2 need to be stacked, the rear stop bar 25 is pulled out of the fixing slot 212, keeping the rear of the pallet 2 flat and facilitating the stable placement of the upper pallet 2. The pulled-out rear stop bar 25 can be placed in a dedicated storage slot provided on the pallet frame 21 to prevent loss.

[0070] It is worth noting that, referring to the appendix Figure 10 As shown, the pallet frame 21 is provided with multiple fixing slots 212 at intervals along the pallet moving direction. In this way, the rear stop bar 25 can be reasonably selected into which fixing slot 212 according to the number of shared bicycles loaded on a single pallet 2. For example, when the pallet 2 is fully loaded with shared bicycles, the rear stop bar 25 is inserted into the fixing slot 212 at the rear end of the pallet. When the pallet 2 is not fully loaded, the appropriate fixing slot 212 is selected behind multiple bicycles to insert the rear stop bar according to the position of the shared bicycles on the pallet frame 21.

[0071] The front stop lever 24 and rear stop lever 25 form obstructions at the front and rear ends of the bicycle, respectively, together with the wheel limiting structures 211 on both sides, to provide all-around restraint for the bicycle. The wheel limiting structures 211 restrict the lateral displacement of the wheels, the front stop lever 24 restricts the forward displacement of the bicycle, and the rear stop lever 25 restricts the backward displacement of the bicycle. The three work together to reliably fix the bicycle to the pallet 2 during transportation, preventing any directional movement. At the same time, the hinged design of the front stop lever 24 and the insertable design of the rear stop lever 25 allow both to be folded up or removed when pallets 2 need to be stacked, keeping the upper surface of the pallet 2 flat and creating conditions for the vertical stacking of multiple pallets 2.

[0072] In some embodiments, refer to the appendix Figure 2 and 15 As shown, guide rails 111 are fixedly installed on both sides of the storage platform 11 along the direction perpendicular to the movement of the tray 2. The guide rails 111 guide the guide wheels 22 into their respective positions. When the tray 2 moves from the lifting tail plate assembly 3 into the storage platform 11, the guide wheels 22 smoothly transition from the guide groove 321 of the lifting tail plate assembly 3 into the guide rails 111 of the storage platform 11. The guide rails 111 continue to guide and limit the guide wheels 22, ensuring that the tray 2 maintains a straight line movement on the storage platform 11 consistent with the direction of movement, preventing deviation. The guide rails 111 and the guide groove 321 are connected end-to-end at the docking point, forming a continuous guide path, ensuring a smooth transition of the tray 2 from the lifting tail plate assembly 3 to the storage platform 11.

[0073] Correspondingly, the traveling wheels 23 at the bottom of the tray 2 can smoothly transition from the guide groove 321 into the guide rail 111 to continue providing support for rolling.

[0074] See attached document Figure 2 , 14 As shown in Figure 15, the horizontal transfer mechanism 4 includes a linear module 41 and an actuator 42. The linear module 41 is disposed on the side wall of the carriage 1 and is used to drive the actuator 42 to move horizontally. The linear module 41 serves as a power source, converting electrical or hydraulic energy into mechanical energy for linear motion, providing driving force for the transfer of the pallet 2.

[0075] The actuator 42 is connected to the pallet 2 to drive the pallet 2 to move horizontally between the storage platform 11 and the lifting tail plate assembly 3. The actuator 42 and the pallet 2 are detachably connected. When the pallet 2 needs to be transferred, the actuator 42 connects to the pallet 2, transmitting the driving force of the linear module 41 to the pallet 2, causing the pallet 2 to move along with the actuator 42. When the pallet 2 moves to a predetermined position, the actuator 42 disengages from the pallet 2, allowing the pallet 2 to remain at that position. This detachable connection allows one actuator 42 to connect and disconnect sequentially from multiple pallets 2, enabling the transfer of multiple pallets 2 one by one without requiring an independent drive mechanism for each pallet 2.

[0076] Through the coordination of the above structures, the horizontal transfer mechanism 4 enables bidirectional horizontal movement of the pallet 2 between the storage platform 11 and the lifting tail plate assembly 3. When the pallet 2 needs to be moved from the storage platform 11 to the lifting tail plate assembly 3, the actuator 42 connects to the pallet 2, and the linear module 41 drives the actuator 42 to move towards the rear of the carriage 1, moving the pallet 2 from the storage platform 11 along the guide rail 111 and into the lifting tail plate assembly 3 via the guide groove 321. When the pallet 2 needs to be moved back from the lifting tail plate assembly 3 to the storage platform 11, the actuator 42 connects to the pallet 2, and the linear module 41 drives the actuator 42 to move towards the interior of the carriage 1, moving the pallet 2 from the lifting tail plate assembly 3 into the storage platform 11 via the guide groove 321 and the guide rail 111. The guide rail 111 on the storage platform 11 ensures the guiding accuracy of the pallet 2 when entering and exiting the storage platform 11, and together with the guide groove 321 of the lifting tail plate assembly 3, forms a complete guiding path, ensuring that the pallet 2 maintains stable linear movement throughout the entire transfer process.

[0077] In this embodiment, the linear module 41 serves as a power source, converting electrical or hydraulic energy into mechanical energy for linear motion, providing driving force for the transfer of the pallet 2. The linear module 41 can be implemented in various specific structural ways, which are described below.

[0078] In one implementation, the linear module 41 is a sprocket and chain structure. Specifically, at least two sprockets are arranged horizontally on the side wall of the carriage 1, including a driving sprocket and a driven sprocket, which are connected by a closed-loop chain. The driving sprocket is connected to a drive source (such as a motor), and when the motor drives the driving sprocket to rotate, the chain moves in a circular motion. The actuator 42 is fixedly connected to the chain and moves horizontally along with the chain. Since there is a definite correspondence between the points on the chain and the rotation angle of the sprockets, by controlling the rotation angle and number of revolutions of the motor, the actuator 42 can be precisely stopped at a predetermined position, realizing step-like movement.

[0079] The stepping characteristics of the sprocket and chain structure are adapted to the loading cycle height of the multi-pallet 2 in this application. Multiple pallets 2 are arranged horizontally on the storage platform 11 inside the carriage 1, with a fixed spacing between adjacent pallets 2. The actuator 42 needs to connect and disconnect from each pallet 2 sequentially to move the pallets 2 one by one to the lifting tail plate assembly 3. By controlling the motor to drive the sprocket to rotate at a specific angle, the chain drives the actuator 42 to move a fixed distance, which is exactly equal to the center distance between two adjacent pallets 2. In this way, the actuator 42 can sequentially align with the first pallet 2, the second pallet 2, and so on until all pallets 2 are removed, completing the sequential removal operation. When it is necessary to pull the pallets 2 back from the lifting tail plate assembly 3 to the storage platform 11, distance control is also used to make the actuator 42 sequentially align with the parking positions of each pallet 2, completing the connection and pull-back actions.

[0080] Another advantage of the sprocket and chain structure is its strong load-bearing capacity and stable operation, making it suitable for the heavy load conditions of shared bicycles P. As a flexible transmission component, the chain can adapt to the long length of the carriage 1, and the manufacturing cost of the sprocket and chain is relatively low, making maintenance convenient. In addition, multiple fixed points can be set on the chain to connect with the actuator 42, so that one linear module 41 can drive one actuator 42 to reciprocate along the entire carriage 1, eliminating the need for a separate drive for each pallet 2, resulting in a simple and efficient structure.

[0081] In another implementation, the linear module 41 is a lead screw module. Specifically, a lead screw is installed horizontally on the side wall of the carriage 1. The lead screw is connected to a motor drive, and a nut seat is threaded onto the lead screw. The actuator 42 is fixedly connected to the nut seat. When the motor drives the lead screw to rotate, the nut seat moves along the axial direction of the lead screw, thereby driving the actuator 42 to move horizontally. The lead screw module has the advantages of high positioning accuracy and good rigidity, and is suitable for scenarios where the positioning accuracy of the pallet 2 is required to be high.

[0082] In another implementation, the linear module 41 is a synchronous belt module. Specifically, a driving synchronous pulley and a driven synchronous pulley are arranged horizontally on the side wall of the carriage 1, and the two are connected by a synchronous belt. The actuator 42 is fixedly connected to the synchronous belt. When the motor drives the driving synchronous pulley to rotate, the synchronous belt drives the actuator 42 to move horizontally. The synchronous belt module has the advantages of smooth operation and low noise, and is suitable for scenarios with high requirements for smooth operation.

[0083] In another implementation, the linear module 41 is a linear motor module. Specifically, a stator track is provided on the side wall of the carriage 1 in the horizontal direction, and a mover is provided on the actuator 42. The mover moves along the stator track under electromagnetic action. The linear motor module has the advantages of fast response speed and high positioning accuracy, and is suitable for scenarios with high requirements for transfer efficiency.

[0084] Through the above-described various implementation methods, the linear module 41 can select a suitable specific structure according to actual application requirements. The sprocket and chain structure, due to its advantages such as convenient stepping control, strong load-bearing capacity, and low cost, is particularly suitable for the sequential transfer of multiple pallets 2 in this application. The actuator 42 and pallet 2 are detachably connected. When pallet 2 needs to be transferred, the actuator 42 connects to pallet 2, and the linear module 41 drives the actuator 42 to move, causing pallet 2 to move from the storage platform 11 along the guide rail 111 and into the lifting tail plate assembly 3 via the guide groove 321; or from the lifting tail plate assembly 3 into the storage platform 11 via the guide groove 321 and the guide rail 111. The guide rail 111 on the storage platform 11 and the guide groove 321 of the lifting tail plate assembly 3 are connected end-to-end at the docking point, forming a continuous guide path, ensuring that pallet 2 maintains stable linear motion throughout the entire transfer process.

[0085] In some embodiments, a plurality of retractable positioning pins 112 are provided at intervals along the length of the storage platform 11. The positioning pins 112 are used to define the position of the tray 2 located on the storage platform 11. Refer to the attached figure. Figure 2 As shown, in some preferred embodiments, the positioning pins 112 are spaced apart along the length of the guide rail 111, and the spacing between them corresponds to the arrangement spacing of the trays 2 on the storage platform 11, so that each tray 2 has a corresponding positioning pin 112 on the storage platform 11 to limit its position.

[0086] When the pallet 2 is pulled from the lifting tail assembly 3 into the storage platform 11 by the horizontal transfer mechanism 4 and moved to the predetermined parking position, the positioning pin 112 extends to lock the position of the pallet 2. The positioning pin 112 can extend vertically, cooperating with the corresponding positioning hole or positioning groove on the pallet 2 to prevent the pallet 2 from shifting along its direction of movement on the storage platform 11. Alternatively, it can block the traveling wheels 23 on the pallet 2 from moving outwards from the carriage 1.

[0087] In this way, even if the vehicle encounters bumpy roads or emergency braking during the journey, the pallet 2 will not slide back and forth, ensuring the stability and safety of the pallet 2 and the bicycle it carries during transportation.

[0088] When pallet 2 needs to be moved from storage platform 11 to lifting tail assembly 3, positioning pin 112 retracts, releasing the lock on pallet 2 and allowing it to move freely. The extension and retraction of positioning pin 112 can be controlled by a drive component such as an electromagnet, cylinder, hydraulic cylinder, or electric push rod, and is linked with the control system to achieve automated control. After the actuator 42 of the horizontal transfer mechanism 4 is connected to pallet 2, the control system issues a command to retract positioning pin 112, and then actuator 42 drives pallet 2 to move out of storage platform 11.

[0089] In some embodiments, the actuator 42 includes a connecting rod 421 and a second locking mechanism 422. One end of the connecting rod 421 is fixedly connected to the drive end of the linear module 41, and the other end is connected to the second locking mechanism 422. The connecting rod 421 acts as a force-transmitting component, transmitting the driving force generated by the linear module 41 from the drive end to the second locking mechanism 422, allowing the second locking mechanism 422 to move horizontally along with the drive end of the linear module 41. The length and stiffness of the connecting rod 421 are determined according to the width of the carriage 1 and the force requirements, ensuring that it does not deform or break when transmitting driving force.

[0090] The second locking mechanism 422 is used to lock the connection with the tray 2. The second locking mechanism 422 is located at the end of the connecting rod 421 away from the driving end of the linear module 41. When the tray 2 needs to be transferred, the second locking mechanism 422 locks the tray 2, making the tray 2 and the actuator 42 form a single unit, moving horizontally together with the driving end of the linear module 41. When the tray 2 moves to a predetermined position, the second locking mechanism 422 separates from the tray 2, releasing the locking connection and allowing the tray 2 to remain at that position, while the actuator 42 can continue to move to connect to the next tray 2.

[0091] Through the cooperation of connecting rod 421 and second locking mechanism 422, actuator 42 achieves a detachable connection with pallet 2. This detachable connection allows one actuator 42 to connect and disconnect from multiple pallets 2 sequentially, thereby enabling the sequential transfer of multiple pallets 2. When multiple pallets 2 need to be moved sequentially from storage platform 11 to lifting tail assembly 3, actuator 42 first locks itself to the first pallet 2, and linear module 41 drives actuator 42 to move towards the rear of carriage 1, moving the first pallet 2 to lifting tail assembly 3; then the second locking mechanism 422 separates from the first pallet 2, actuator 42 returns to the position of the second pallet 2, locks itself to the second pallet 2, and moves it out; the above steps are repeated until all pallets 2 have been moved out. Similarly, when pallets 2 need to be moved from lifting tail assembly 3 back to storage platform 11, actuator 42 locks itself to each pallet 2 sequentially and pulls it back.

[0092] With the above structure, a single linear module 41 and an actuator 42 can complete the transfer operation of all pallets 2, eliminating the need for an independent drive mechanism for each pallet 2. This significantly simplifies the system structure and reduces manufacturing costs and maintenance difficulty. Simultaneously, the connecting rod 421 allows the linear module 41 to be positioned on the side wall of the carriage 1, while the second locking mechanism 422 can extend to the location of the pallet 2, achieving spatial separation between the power source and the actuator, facilitating a rational layout within the carriage 1.

[0093] In some embodiments, the second locking mechanism 422 includes a mounting base 4221, a second stop 4222, and a second drive 4223. The mounting base 4221 is fixedly disposed at the end of the connecting rod 421, serving as the base of the second locking mechanism 422 and providing a mounting foundation for the second stop 4222 and the second drive 4223. The structure of the mounting base 4221 is determined according to the arrangement of the second stop 4222 and the second drive 4223, and can be configured as a box or a plate to facilitate the assembly and protection of internal parts.

[0094] The second driving member 4223 is used to drive the second stop member 4222 to move vertically relative to the mounting base 4221. Under the drive of the second driving member 4223, the second stop member 4222 can extend or retract. When extended, the second stop member 4222 locks with the mating part 26 on the tray 2 to achieve a locking connection between the actuator 42 and the tray 2; when retracted, the second stop member 4222 separates from the mating part 26, releasing the connection between the actuator 42 and the tray 2.

[0095] The tray 2 is provided with a mating part 26 that mates with the second stop 4222. The position of the mating part 26 corresponds to that of the second stop 4222. When the second stop 4222 extends vertically under the drive of the second drive member 4223, the second stop 4222 and the mating part 26 form a locking engagement, fixing the tray 2 to the actuator 42. When the second stop 4222 retracts, the locking engagement is released, and the tray 2 separates from the actuator 42. The mating part 26 can be configured as a positioning hole, a slot, a locking member 261, or other structures that can reliably lock with the second stop 4222.

[0096] The second driving component 4223 can be implemented in various ways.

[0097] In one implementation, the second driving component 4223 is an electric push rod. The cylinder of the electric push rod is fixed to the mounting base 4221, and the push rod end is connected to the second stop 4222. When locking is required, the electric push rod is energized and extends, pushing the second stop 4222 downward. The second stop 4222 inserts into the mating part 26 (such as a positioning hole) on the tray 2, forming a locking engagement. When unlocking is required, the electric push rod retracts, driving the second stop 4222 upward, disengaging it from the mating part 26, and releasing the lock. The electric push rod is uniformly controlled by the control system and can be linked with the movement of the linear module 41 to achieve automated operation.

[0098] In another embodiment, the second driving member 4223 is a compression spring. The compression spring is disposed within the mounting base 4221 and continuously applies a downward preload to the second stop member 4222, keeping the second stop member 4222 in its extended position in its natural state. The lower end of the second stop member 4222 is configured as a roller. The mating portion 26 on the tray 2 is a fixedly mounted clamping member 261, with a groove 262 in the center of the clamping member 261, and arc-shaped guide surfaces 263 on both sides of the clamping member 261 along the moving direction of the tray 2. When the actuator 42 moves to the position of the tray 2 and aligns with it, the roller at the lower end of the second stop 4222 presses against the sliding guide surface of the locking member 261 under the action of the compression spring. As the actuator 42 continues to move, the roller slides along the arc-shaped guide surface 263 and compresses the spring, causing the second stop 4222 to retract. When the roller crosses the arc-shaped guide surface 263 and enters the groove 262 in the middle of the locking member 261, the second stop 4222 pops out downward under the action of the compression spring, and the roller locks into the groove 262, forming a locking engagement. When unlocking is required, the roller can be pushed out of the groove 262 again by external pulling force or the reverse action of the actuator 42. This structure does not require an external power supply and automatically locks by relying on the spring preload, making it simple and reliable.

[0099] In another implementation, the second driving component 4223 is an electromagnet. The coil of the electromagnet is fixed to the mounting base 4221, and the armature is connected to the second stop 4222. When locking is required, the electromagnet is energized, and the armature, under the action of electromagnetic force, drives the second stop 4222 downward, inserting it into the mating part 26 to form a lock. At this time, the mating part 26 can be a positioning hole provided on the tray 2. When unlocking is required, the electromagnet is de-energized, and the second stop 4222 retracts under the action of the return spring. The electromagnet has a fast response speed and is suitable for working conditions that require frequent locking and unlocking.

[0100] In some embodiments, the lifting mechanism 5 is disposed at the rear of the carriage 1 and is used to drive the lifting tail plate assembly 3 to rise and fall in the vertical direction so that any pallet 2 on the lifting tail plate assembly 3 is flush with the corresponding storage platform 11 inside the carriage 1.

[0101] The lifting mechanism 5 can be implemented using various driving methods, such as screw lifting mechanism, rack and pinion lifting mechanism, scissor lifting mechanism or chain drive lifting mechanism, etc.

[0102] In this embodiment, a chain-driven lifting mechanism is preferably used. Specifically, the lifting mechanism 5 includes a cylinder and a chain drive assembly. The cylinder is installed vertically, and one end of the chain is connected to the bottom of the cylinder. The chain passes over a pulley located at the top of the cylinder piston rod at the rear of the carriage 1 and connects to the lifting tail plate assembly 3. When the cylinder piston rod extends, the chain drives the lifting tail plate assembly 3 to rise; when the cylinder piston rod retracts, the chain drives the lifting tail plate assembly 3 to fall. By using a chain-driven transmission method that passes over the pulley, the lifting stroke of the lifting tail plate assembly 3 can be twice the stroke of the cylinder piston rod, thus achieving a doubling of the stroke.

[0103] This multiplied stroke design allows for a wider range of lifting and lowering movements using cylinders with shorter strokes within the limited installation space at the rear of the carriage 1, meeting the lifting and lowering requirements of the lifting tailgate assembly 3 from the ground to the various storage platforms 11 within the carriage 1. The cylinders can be pneumatic, electric, or hydraulic, with the appropriate drive method selected based on the actual load and operating environment. Driven by the lifting mechanism 5, the lifting tailgate assembly 3 can raise or lower multiple stacked pallets 2 as a whole, ensuring that any pallet 2 accurately reaches the same height as the corresponding storage platform 11 within the carriage 1, providing the necessary leveling conditions for the horizontal movement of the pallets 2.

[0104] In some embodiments, the lifting tailgate assembly 3 can be flipped relative to the carriage 1. When the lifting tailgate assembly 3 is flipped to a vertical position, it can close the opening at the rear of the carriage 1, acting as a door for the carriage 1 and reducing the overall length of the vehicle. When loading a single vehicle, the lifting tailgate assembly 3 is flipped to a horizontal position, serving as a working platform for the pallet 2 to enter, exit, and be stacked. The flipping of the lifting tailgate assembly 3 can be achieved manually or automatically using drive components such as motors, cylinders, and hydraulic cylinders to adapt to scheduling operation requirements with different levels of automation.

[0105] In some embodiments, the front end of the tail plate frame 31 is provided with a loading ramp 34, which facilitates the shared bicycle P to be smoothly pushed into the tray 2 along the loading ramp.

[0106] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
