Description

Technical Field

[0001] The present invention relates to the technical field of parcel box equipment, and in particular to an intelligent parcel box. Background Art

[0002] In recent years, with the rapid development of e-commerce and the logistics industry, smart parcel boxes, as key end-to-end delivery facilities, have played a significant role in improving delivery efficiency and facilitating user pickup. However, existing smart parcel boxes still suffer from numerous technical deficiencies in practical applications, primarily in terms of volume allocation, space utilization, and overall structural design.

[0003] First, existing smart parcel boxes typically feature fixed compartment sizes, making the ratio of large, medium, and small compartments difficult to flexibly adjust based on the actual needs of different communities. For example, in areas primarily used for small parcels, small compartments are often in short supply, while large compartments remain unused for extended periods. Conversely, in areas with a high concentration of large parcels, small compartments may be in excess while large compartments are insufficient. This irrational volume allocation leads to significant waste of parcel box space resources and increases the inconvenience faced by users who are unable to store their parcels due to mismatched compartment sizes.

[0004] Secondly, the fixed compartment volume of traditional smart parcel boxes limits the size range of packages they can accommodate. For larger packages that exceed the standard size, users are often unable to use the parcel boxes and are forced to choose other delivery methods, which reduces the user experience. Furthermore, the phenomenon of small packages occupying large compartments further exacerbates space waste and reduces the overall operational efficiency of the parcel boxes. Summary of the Invention

[0005] In response to the problems existing in the existing technology, an intelligent parcel box is provided. By setting a foldable and expandable partition structure inside the box body and adopting a clutch transmission mechanism in the drive mechanism, the torque output by the servo motor is transmitted to the rotary folding mechanism, thereby driving the partition to realize the expansion or folding operation. When a large box is needed, multiple small boxes can be automatically combined with the cooperation of the servo motor and the corresponding clutch transmission mechanism to form an overall large-capacity space, which solves the problem of fixed grids and non-adjustable volume of traditional parcel boxes.

[0006] To solve the problems of the prior art, the present invention provides an intelligent parcel box, comprising a box body and a partition arranged in the box body, the partition comprising at least two folding plates arranged along the depth direction of an inner cavity of the box body; the box body further comprises a control installation cavity, in which a driving mechanism for driving the folding plates to fold or unfold along the depth direction of the inner cavity of the box body is provided, the driving mechanism comprising a driving shaft, which is arranged in the control installation cavity along the height direction of the box body and is used to generate rotational power; a servo motor, which is arranged in the control installation cavity, and the output shaft of the servo motor is transmission-connected to the driving shaft; a rotary folding mechanism, which is arranged on both sides of the inner cavity of the box body and transmission-connected to the folding plates, the rotary folding mechanism comprising a driven shaft that can rotate to drive the folding plates to unfold and fold; and a clutch transmission mechanism, which transmission-connects the driving shaft and the driven shaft to realize driving or disconnecting transmission as needed.

[0008] Preferably, the rotary folding mechanism includes a rotating plate, which is rotatably arranged on both sides of the inner cavity of the box, and a guide groove is provided on the rotating plate, extending along a radial direction of rotation deviating from the rotating plate. The follower pin passes through the guide rail and slides with the guide groove. When the rotating plate rotates, the follower pin is guided to move toward the inner cavity of the box to fold the folding plate.

[0009] Preferably, the outer side of the rotating plate is provided with teeth distributed circumferentially along its rotation axis, the driven shaft extends along the width direction of the box body and is rotatably arranged in the box body, and driven gears meshing with the teeth are provided at both ends of the driven shaft.

[0010] Preferably, the clutch transmission mechanism includes a bracket, which is arranged in the control mounting cavity, and the driving shaft passes through the bracket in a vertical direction and is rotatably connected to the bracket; a clutch shaft, which is rotatably arranged on the bracket and parallel to the driving shaft, and the clutch shaft is transmission-connected to the driven shaft; a fixed bevel gear, which is coaxially and fixedly arranged on the driving shaft; a movable bevel gear, which is spline-connected to the clutch shaft; a clutch, which is arranged on the bracket and is used to drive the movable bevel gear to engage with the fixed bevel gear; and an elastic reset element, which is sleeved on the clutch shaft and located between the movable bevel gear and the bottom end of the bracket, and is used to reset the movable bevel gear out of the fixed bevel gear when the clutch is released.

[0011] Preferably, the clutch includes a movable magnetic ring, which is coaxially fixedly arranged on the top of the movable bevel gear; an electromagnet, which is arranged at the bottom end of the bracket and faces the movable magnetic ring. When the electromagnet is energized, it attracts the movable magnetic ring to drive the movable bevel gear to move along the clutch axis toward the fixed bevel gear to achieve engagement.

[0028] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1-4As shown, a smart parcel box includes a box body 1 and a partition arranged in the box body 1, the partition including at least two folding plates 2 arranged along the depth direction of the inner cavity of the box body 1; the box body 1 also has a control installation cavity, in which a driving mechanism for driving the folding plates 2 to fold or unfold along the depth direction of the inner cavity of the box body 1 is provided, and the driving mechanism includes a driving shaft 31, which is arranged in the control installation cavity along the height direction of the box body 1 and is used to generate rotational power; a servo motor 32, which is arranged in the control installation cavity, and the output shaft of the servo motor 32 is transmission-connected to the driving shaft 31; a rotary folding mechanism 33, which is arranged on both sides of the inner cavity of the box body 1 and is transmission-connected to the folding plates 2, and the rotary folding mechanism 33 has a driven shaft 331 that can rotate to drive the folding plates 2 to unfold and fold; a clutch transmission mechanism 34, which transmission-connects the driving shaft 31 and the driven shaft 331 to realize driving or disconnecting transmission as needed.

[0030] A smart parcel box includes a box body 1 and a foldable partition assembly arranged inside the box body 1. The partition assembly is composed of a plurality of foldable panels 2 arranged at intervals along the depth direction of the inner cavity of the box body 1. The foldable panels 2 can be expanded or folded within the inner cavity space of the box body 1 to achieve flexible adjustment of the volume of the box body 1.

[0031] The box body 1 is provided with a control installation cavity, in which a driving mechanism for driving the folding plate 2 to unfold or fold is integrated. The driving mechanism includes: The drive shaft 31 is arranged in the control installation cavity along the height direction of the box body 1 and is used to transmit the rotational driving force; The servo motor 32 is installed in the control installation cavity, and its output shaft is connected to the drive shaft 31 to provide a stable and controllable power source; The rotating folding mechanism 33 is respectively arranged on the left and right sides of the inner cavity of the box body 1, and is connected to the folding plate 2 in a transmission manner. A rotatable driven shaft 331 is provided inside the folding plate 2 to drive the folding plate 2 to achieve synchronous expansion and folding. The clutch transmission mechanism 34 is provided between the driving shaft 31 and the driven shaft 331 and adopts a controllable clutch method to transmit power, so that the driving shaft 31 can drive the driven shaft 331 to work under certain conditions, and can also interrupt the transmission in a non-working state.

[0032] Through the above-mentioned structural configuration, the smart parcel box can be driven by the servo motor 32 and selectively transmit power to the rotary folding mechanism 33 through the clutch transmission mechanism 34 to achieve automatic folding and unfolding of the partitions, thereby flexibly adjusting the spatial layout of the box body 1 according to different item sizes or transportation requirements.

[0033] By incorporating foldable partitions and an intelligent drive control system, the volume of the box 1 can be adjusted in multiple levels and expanded in a modular manner. Especially when a large-capacity parcel box is needed, multiple smaller boxes can automatically deploy their internal partitions and combine in a coordinated manner under the control system's command, forming a unified, continuous, large space to accommodate large items. This solution effectively solves the problems of traditional parcel boxes with fixed structures and rigid volumes, improving space utilization efficiency.

[0034] like Figure 5 、 Figure 9 and Figure 10 As shown, follower pins 21 are provided at the center positions of both ends of the folding plates 2, and the side edges of adjacent folding plates 2 are connected by hinges. Guide rails 11 that slide with the follower pins 21 are provided on both sides of the inner cavity of the box body 1; the follower pins 21 of the folding plates 2 located on the inner side of the box body 1 are transmission-connected with the rotary folding mechanism 33. When the rotary folding mechanism 33 drives the follower pins 21 to move into the box body 1, each folding plate 2 is synchronously folded inwardly under the guidance of the guide rails 11 to form a continuous folding movement.

[0035] Follower pins 21 are respectively provided at the center positions of both ends of the folding plate 2, and the side edges of adjacent folding plates 2 are hinged to each other through rotating connecting parts; guide rails 11 that slide with the follower pins 21 are provided on the left and right sides of the inner cavity of the box body 1, and the guide rails 11 extend along the depth direction of the box body 1 to guide the movement path of the folding plate 2; the follower pins 21 of the folding plate 2 located at the inner side of the box body 1 are directly connected to the rotary folding mechanism 33. When the rotary folding mechanism 33 drives the follower pins 21 to move into the box body 1 along the guide rails 11, each folding plate 2 folds inward synchronously under the constraint and guidance of the guide rails 11, realizing the continuous folding movement of the folding plate 2, thereby effectively closing the space inside the box body 1; when driven in reverse, the folding plates 2 can be unfolded synchronously to increase the internal volume of the box body 1.

[0036] like Figure 6 、 Figure 9 and Figure 10 As shown, the rotary folding mechanism 33 includes a rotating plate 332, which is rotatably arranged on both sides of the inner cavity of the box body 1. The rotating plate 332 is provided with a guide groove 3321 extending along a radial direction of rotation deviating from the rotating plate 332. The follower pin 21 passes through the guide rail 11 and slides with the guide groove 3321. When the rotating plate 332 rotates, it guides the follower pin 21 to move toward the inner cavity of the box body 1 to fold the folding plate 2.

[0037] Adjacent folding plates 2 are hingedly connected via rotating connectors, and guide rails 11 extending along the depth of the box body 1 are provided on both sides to limit the movement of the follower pins 21. The follower pins 21 of the folding plates 2 closest to the inside of the box body 1 engage with the guide slots 3321 on the rotating plate 332.

[0038] The guide rail 11 extends along the depth direction of the inner cavity of the box body 1 to limit the movement direction of the driven pin 21; adjacent folding plates 2 are hinged by rotating connecting members so that they can generate continuous linkage under force driving.

[0039] During operation, when the servo motor 32 is activated and drives the rotating plate 332 to rotate via the clutch transmission mechanism 34, the guide slot 3321 drives the follower pin 21, which slides inward along the guide rail 11, thereby guiding the folding plates 2 to fold inward in sequence. During reverse rotation, the folding plates 2 simultaneously unfold. This structure enables the folding plates 2 to achieve coordinated and smooth folding / unfolding movement within a limited space, completing the dynamic reconfiguration of the volume of the box 1.

[0040] like Figure 9 and Figure 10 As shown, the outer side of the rotating plate 332 is provided with teeth distributed circumferentially along its rotation axis, the driven shaft 331 extends along the width direction of the box body 1 and is rotatably arranged in the box body 1, and the two ends of the driven shaft 331 are provided with driven gears 333 meshing with the teeth.

[0041] The rotary folding mechanism 33 includes: rotating plates 332, which are respectively rotatably arranged on the left and right sides of the inner cavity of the box body 1. The outer side of each rotating plate 332 is provided with a tooth structure distributed along its circumference. The rotating plate 332 is also provided with a guide groove 3321 extending away from the radial direction, which is used to guide the follower pin 21 to move along a nonlinear path. A follower pin 21 is provided at each end of the folding plate 2, which passes through the guide rails 11 on both sides of the box body 1 and slides with the guide groove 3321 of the corresponding rotating plate 332. The guide rail 11 is set along the depth direction of the box body 1, which is used to limit the sliding direction of the follower pin 21 and guide it to move along a predetermined path during folding and unfolding. Adjacent folding plates 2 are hingedly connected by a rotating connecting member to form a linked folding structure.

[0042] The driven shaft 331 is arranged horizontally along the width of the housing 1 and is rotatably disposed within the housing 1. A driven gear 333 is mounted on each end of the driven shaft 331, and each driven gear 333 meshes with the circumferential teeth on the corresponding rotating plate 332. By rotating the driven shaft 331, the driven gears 333 at both ends can be rotated simultaneously, thereby driving the rotating plates 332 on the left and right sides to rotate synchronously. The guide slots 3321 connected to the rotating plates 332 drive the driven pins 21 along the guide rails 11, achieving the synchronous unfolding or folding of the folding plates 2. Because the driven pins 21 at both ends of the folding plates 2 are respectively connected to the rotating plates 332 on the left and right sides, the synchronous rotation of the guide slots 3321 drives the driven pins 21 to operate simultaneously under force on both sides, thereby ensuring that the folding plates 2 always maintain a stable posture during movement, avoiding unbalanced loading or jamming, and significantly improving the reliability of the structure and the coordination of the folding action.

[0043] like Figure 7 and Figure 8 As shown, the clutch transmission mechanism 34 includes a bracket 341, which is arranged in the control mounting cavity, and the drive shaft 31 passes through the bracket 341 in the vertical direction and is rotatably connected thereto; a clutch shaft 342, which is rotatably arranged on the bracket 341 and parallel to the drive shaft 31, and the clutch shaft 342 is transmission-connected to the driven shaft 331; a fixed bevel gear 343, which is coaxially and fixedly arranged on the drive shaft 31; a movable bevel gear 344, which is spline-connected to the clutch shaft 342; a clutch, which is arranged on the bracket 341 and is used to drive the movable bevel gear 344 to engage with the fixed bevel gear 343; and an elastic reset element 347, which is sleeved on the clutch shaft 342 and is located between the movable bevel gear 344 and the bottom end of the bracket 341, and is used to reset the movable bevel gear 344 and disengage from the fixed bevel gear 343 when the clutch is released.

[0044] The clutch transmission mechanism 34 is disposed within the control mounting cavity and includes a bracket 341, a drive shaft 31, a clutch shaft 342, a fixed bevel gear 343, a movable bevel gear 344, a clutch, and an elastic reset element 347. The bracket 341 is mounted within the control mounting cavity, with the drive shaft 31 vertically extending through the bracket 341 and rotatably connected thereto. The clutch shaft 342 is disposed parallel to the drive shaft 31, rotatably mounted on the bracket 341, and in transmission connection with the driven shaft 331. The fixed bevel gear 343 is coaxially fixedly mounted on the drive shaft 31, while the movable bevel gear 344 is connected to the clutch shaft 342 via a spline structure. The clutch is mounted on the bracket 341 and is used to drive the movable bevel gear 344 to move axially, engaging or disengaging with the fixed bevel gear 343, thereby controlling the power transmission between the drive shaft 31 and the clutch shaft 342. The elastic reset element 347 is sleeved on the clutch shaft 342 and is located between the movable bevel gear 344 and the bottom end of the bracket 341. When the clutch is in the released state, the elastic reset element 347 provides axial elastic force to make the movable bevel gear 344 automatically retract to the initial position disengaged from the fixed bevel gear 343, ensuring that the drive disconnection state is reliably maintained.

[0045] In actual operation, after the servo motor 32 is activated, it transmits power vertically to the clutch transmission mechanism 34 via the drive shaft 31. When the clutch is in the driving state, the fixed bevel gear 343 fixed on the drive shaft 31 meshes with the movable bevel gear 344 on the clutch shaft 342. Under the action of the gear meshing force, a power connection is established between the drive shaft 31 and the clutch shaft 342, and the rotational motion of the drive shaft 31 is transmitted to the clutch shaft 342. Because the clutch shaft 342 forms a transmission connection with the driven shaft 331, the clutch shaft 342 further drives the driven shaft 331 to rotate, causing the driven gears 333 at both ends of the driven shaft 331 to rotate synchronously, respectively driving the rotating plates 332 located on the left and right sides of the box body 1 to rotate synchronously, thereby driving the driven pins 21 at both ends of the folding plate 2 to slide synchronously along the guide rail 11, completing the unfolding or folding process of the folding plate 2.

[0046] When the clutch is released, the elastic reset element 347 releases its stored energy in its compressed state, causing the movable bevel gear 344 to retract axially under the action of the elastic force, disengaging it from the fixed bevel gear 343. This disconnects the power transmission path between the drive shaft 31 and the clutch shaft 342, placing the system in a no-load standby state. This structure effectively prevents the servo motor 32 from being misactivated or generating excessive load in the system during non-operating conditions, thereby improving the mechanism's energy efficiency and safety. Furthermore, the clutch's controllable meshing characteristics enable precise start-stop control of the folding mechanism, further enhancing the system's responsiveness and operational stability.

[0047] like Figure 7 and Figure 8 As shown, the clutch includes a movable magnetic ring 345, which is coaxially fixedly arranged on the top of the movable bevel gear 344; an electromagnet 346, which is arranged at the bottom end of the bracket 341 and faces the movable magnetic ring 345. When the electromagnet 346 is energized, it attracts the movable magnetic ring 345 and drives the movable bevel gear 344 to move along the clutch shaft 342 toward the fixed bevel gear 343 to achieve engagement. When the power is off, the electromagnet 346 is reset and disengaged under the action of the elastic reset element 347.

[0048] The clutch comprises a movable magnetic ring 345 and an electromagnet 346. The movable magnetic ring 345 is coaxially fixed to the top of the movable bevel gear 344. The electromagnet 346 is mounted at the bottom of the bracket 341, with its magnetic force directed toward the movable magnetic ring 345. During operation, when energized, the electromagnet 346 generates a magnetic field that attracts the movable magnetic ring 345 and drives it upward, causing the movable bevel gear 344 to slide axially along the clutch shaft 342 toward the fixed bevel gear 343, causing the two bevel gears to mesh and establish a power connection between the drive shaft 31 and the clutch shaft 342. When powered off, the electromagnet 346 loses its attractive force, and the movable bevel gear 344, under the action of the elastic reset element 347, automatically returns to its initial position in the opposite direction, disengaging from the fixed bevel gear 343 and disconnecting the power transmission path. This control method uses the electromagnet 346 to switch on and off the power to achieve precise switching of the clutch state. It does not require mechanical contact or additional drive components. It has a fast response speed and high control accuracy. It is suitable for folding system application scenarios that require frequent switching of working states or remote control.

[0049] like Figure 7 and Figure 8 As shown, the contact surface between the bracket 341 and the movable magnetic ring 345 is provided with tooth grooves 3411 distributed circumferentially along the clutch shaft 342, and the top of the movable magnetic ring 345 is provided with racks 3451 distributed along its circumference. In the initial state of the movable magnetic ring 345, the rack 3451 is engaged with the tooth grooves 3411.

[0050] The contact surface between the bracket 341 and the movable magnetic ring 345 is provided with a plurality of tooth grooves 3411 distributed circumferentially along the clutch shaft 342. A corresponding rack 3451 is provided at the top of the movable magnetic ring 345, also distributed circumferentially. When the movable magnetic ring 345 is in its initial state (i.e., the electromagnet 346 is de-energized and the movable bevel gear 344 is not engaged), the rack 3451 engages with the tooth grooves 3411, forming a reliable mechanical stop, effectively preventing the movable magnetic ring 345, its connected movable bevel gear 344, and the clutch shaft 342 from rotating. This structural arrangement ensures that when the clutch is not operating, the clutch shaft 342 cannot be passively rotated due to external disturbances or inertia, thus avoiding potential problems such as angular deviation of the driven shaft 331. This helps maintain the system's initial precise alignment and stability, providing a foundation for precise control of the subsequent folding action.

[0051] like Figure 7 and Figure 8 As shown, the driving mechanism further includes a locking transmission mechanism 4 provided on the bracket 341 . The locking transmission mechanism 4 is connected to the driven shaft 331 and the clutch shaft 342 for locking the rotation angle of the driven shaft 331 .

[0052] The locking transmission mechanism 4 forms a transmission connection with the driven shaft 331 and the clutch shaft 342, and is used to lock the rotation angle of the driven shaft 331 when the system is not in operation. Through this locking transmission mechanism 4, an angular limiting force can be continuously applied to the driven shaft 331 while the electromagnet 346 is de-energized and the movable bevel gear 344 is disengaged. This further prevents the driven shaft 331 and the rotating plate 332 connecting its two ends from rotating due to external force disturbances, inertial impact, or system vibration, which could cause the folding plate 2 to shift in state or inaccurate folding angle. This locking measure works in conjunction with the aforementioned rack 3451-tooth groove 3411 limiting mechanism to provide dual protection for the folding system, allowing the folding plate 2 to reliably maintain its original angle even in the standby or stopped state, thereby improving the system's overall folding accuracy, position stability, and operational safety.

[0053] like Figure 7 and Figure 8 As shown, the locking transmission mechanism 4 includes a worm wheel 41, which is rotatably arranged in the control mounting cavity, and the worm wheel 41 has a wheel shaft that is transmission-connected to the driven shaft 331; a worm 42, which is rotatably arranged on the bracket 341 and transmission-connected to the clutch shaft 342, and the worm wheel 41 and the worm 42 are transmission-connected.

[0054] The axle of the worm 42 and the driven shaft 331 are connected via a roller chain transmission.

[0055] The worm gear 41 is rotatably mounted within the control mounting cavity and includes an axle in transmission connection with the driven shaft 331, enabling rotation of the driven shaft 331 to drive synchronous rotation of the worm gear 41. The worm 42 is rotatably mounted on the bracket 341 and in transmission connection with the clutch shaft 342. The worm 42 and worm gear 41 achieve transmission coordination through helical meshing. When the clutch shaft 342 rotates, it drives the worm 42, which in turn drives the angular position of the driven shaft 331 through the worm 42-worm gear 41 transmission path. Because the worm 42 transmission has a one-way self-locking characteristic, when an external force attempts to drive the driven shaft 331 in the opposite direction (i.e., when power is input from the worm gear 41), the worm 42 is not driven to rotate. This creates a reliable self-locking effect, effectively preventing the driven shaft 331 and its connecting structure from passively rotating when not in operation, further enhancing the stability and safety of the folding system.

[0056] like Figure 7 and Figure 8 As shown, the locking transmission mechanism 4 further includes a first transmission gear 43 coaxially and fixedly disposed on the top end of the clutch shaft 342 ; a second transmission gear 44 coaxially and fixedly disposed on the top end of the worm 42 , and the second transmission gear 44 is meshed with the first transmission gear 43 .

[0057] The first transmission gear 43 is coaxially fixed to the top of the clutch shaft 342; the second transmission gear 44 is coaxially fixed to the top of the worm 42 and meshes with the first transmission gear 43. Through the meshing structure of this pair of transmission gears, the rotation of the clutch shaft 342 can be directly transmitted to the second transmission gear 44 through the first transmission gear 43, thereby driving the worm 42 to rotate synchronously. The worm 42 is meshed with the worm wheel 41 set in the control mounting cavity. The worm wheel 41 has a wheel shaft that is connected to the driven shaft 331 for transmission, and can synchronously drive the driven shaft 331 to rotate. This structure realizes a complete power transmission chain from the clutch shaft 342, the first transmission gear, the second transmission gear 44, the worm 42, the worm wheel 41 and the driven shaft 331, ensuring the accuracy and synchronization of the movement of the driven shaft 331 during the electronic control switching process. At the same time, due to the self-locking characteristics of the worm gear 42 transmission, even if an external disturbance attempts to drive the driven shaft 331 to reverse, it cannot drive the worm gear 42 in reverse, forming a reliable lock, thereby effectively preventing the rotating plate 332 and the folding plate 2 connected thereto from rotating accidentally due to external force or vibration in the non-working state.

[0058] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention.
