Description

Technical Field

[0001] This application relates to the field of logistics and distribution equipment, and in particular to an intelligent logistics terminal based on a soft and hard composite support structure. Background Technology

[0002] With the continuous improvement of the last-mile logistics and distribution system, intelligent logistics terminals, as core equipment for temporary storage and collection of express parcels, have been widely used in communities, office parks, and other scenarios. The split-type shell is one of the core structures of the intelligent logistics terminal, and its molding precision, lid alignment stability, and structural reliability directly determine the product's production yield and long-term performance.

[0003] Currently, the split-type shells of intelligent logistics terminals in the industry generally adopt a mating structure with male and female stops. The stop structure realizes the alignment guidance and radial limit during the closing process. At the same time, the rigidity of the shell is improved by increasing the shell wall thickness and adding rigid reinforcing ribs, which suppresses the shell deformation during injection molding and use and ensures the closing accuracy.

[0004] However, in actual production and application, the stop structure in the existing shell structure has extremely high tolerance requirements for injection molding. The stop part is prone to shrinkage and warping deformation during the injection molding cooling process, which directly leads to misalignment and poor sealing when the cover is closed. Controlling deformation by thickening the shell and adding rigid reinforcing ribs not only increases the material cost and weight of the product, but also cannot fundamentally solve the problem of deformation after long-term use of the shell. Summary of the Invention

[0005] This application discloses an intelligent logistics terminal based on a soft-hard composite support structure, including: a hard outer shell assembly, a soft inner liner assembly, and a hinge assembly;

[0006] The rigid housing assembly includes a first housing and a second housing, wherein the mating surface between the first housing and the second housing is a planar structure without a stop. The soft inner liner assembly fills and is interference-fitted into the inner cavity of the hard outer shell assembly. The outer contour of the soft inner liner assembly is adapted to the inner contour of the hard outer shell assembly. The elastic support force of the soft inner liner assembly maintains the shape of the first shell and the second shell and the alignment of the mating surfaces. The hinge assembly connects the first housing and the second housing so that the first housing can be opened and closed relative to the second housing.

[0007] Optionally, the hinge assembly is a cross four-bar linkage, and the motion trajectory of the cross four-bar linkage is configured such that the opening angle of the first housing relative to the second housing reaches 180 degrees, and the outer surface of the first housing is in contact with the mounting plane of the second housing.

[0008] Optionally, the rigid housing assembly further includes a flexible storage bag and a fixing strip, wherein the flexible storage bag is fixed to the bottom of the rigid housing assembly by the fixing strip.

[0009] Optionally, the flexible storage bag is provided with a locking component; The rigid housing assembly has a locking component inside that cooperates with the locking component. The locking component includes a driving unit and a reset component, and the driving unit is pulsatorically connected to the reset component. The drive unit is used to overcome the elastic force of the reset member to drive the latching component to release the locking component, and the reset member is used to restore the latching component to the locked state when the drive unit stops driving.

[0010] Optionally, when the flexible storage bag is in a closed state and the locking component is engaged with the buckle component, the flexible storage bag and the rigid outer shell assembly are locked together.

[0011] Optionally, the bottom of the rigid housing assembly is provided with a mechanical emergency lock hole; The mechanical emergency lock hole is provided with a lock cylinder fork, which is connected to the reset member for driving the reset member to move and release the locking component by means of a special key.

[0012] Optionally, an emergency charging port is provided on the top of the rigid housing assembly; The emergency charging interface is electrically connected to the drive unit and is used to provide emergency power to the locking component when there is no internal battery or the battery is depleted.

[0013] Optionally, the outer wall of the rigid housing assembly is provided with a QR code scanning area, which is used for identification of retrieval information to trigger the unlocking of the locking component.

[0014] Optionally, the edge of the mating surface between the first housing and the second housing is provided with an inlet angle structure, the inlet size of which is 3.0mm~4.0mm; The guide angle structure is configured to guide the first housing to slide into alignment relative to the second housing during the closing process.

[0015] Optionally, the second housing is provided with a back plate, and the back plate is provided with a buckle; The second housing is detachably connected to the back plate via the buckle.

[0016] As can be seen from the above technical solutions, this application has the following advantages: The first and second shells are joined by a non-recessed planar joint surface, which, together with a soft inner liner component that is interference-filled into the inner cavity of the outer shell, forms an integrated soft-hard composite support structure. This eliminates the problems of easy deformation during injection molding and difficulty in alignment when closing the lid caused by traditional non-recessed structures. The soft inner liner relies on its own elastic support force to continuously maintain the shape accuracy and flat alignment of the first and second shells and the joint surface. The structure can be stabilized without the need to thicken the shell or add rigid reinforcing ribs, which effectively reduces material costs and the weight of the whole machine. At the same time, the hinge component connecting the two shells is used for opening and closing, which effectively solves the problems of deformation and misalignment that have long existed in the shells of traditional intelligent logistics terminals.

[0022] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1 This application provides a structural schematic diagram of an intelligent logistics terminal based on a soft-hard composite support structure. The application discloses an embodiment of an intelligent logistics terminal based on a soft-hard composite support structure, which includes: a rigid outer shell assembly 1, a soft inner liner assembly 2, and a hinge assembly 3. The rigid housing assembly 1 includes a first housing 11 and a second housing 12, and the mating surface between the first housing 11 and the second housing 12 is a planar structure without a stop. The soft inner liner component 2 fills and is press-fitted into the inner cavity of the hard outer shell component 1. The outer contour of the soft inner liner component 2 is adapted to the inner contour of the hard outer shell component 1. The elastic support force of the soft inner liner component 2 maintains the alignment of the shape and mating surface of the first shell 11 and the second shell 12. The hinge assembly 3 connects the first housing 11 and the second housing 12 so that the first housing 11 can be opened and closed relative to the second housing 12.

[0024] The rigid outer shell assembly 1 serves as the external load-bearing structure of the terminal. It is entirely made of rigid injection molded material to ensure structural strength and external protection. The rigid outer shell assembly 1 includes a first shell 11 and a second shell 12, which together form an internal cavity for accommodating the inner liner and contents. The mating surfaces of the first shell 11 and the second shell 12 are planar structures without locating edges; that is, the mating surfaces of the two shells are flat, continuous, stepless, and without any mating joints, without the raised or recessed locating edges used in traditional shells.

[0025] The soft inner liner assembly 2 is made of a soft material with elastic deformation capability, and is an integral liner structure that matches the shape of the inner cavity of the outer shell. The soft inner liner assembly 2 is assembled into the inner cavity of the rigid outer shell assembly 1 using a filling-type, interference fit method. Its outer contour dimension is slightly larger than the inner contour dimension of the rigid outer shell assembly 1. After assembly, the inner liner is in a slightly compressed state, tightly fitting against the inner wall of the outer shell without gaps or looseness. The outer contour of the soft inner liner assembly 2 is consistent with the inner contour of the rigid outer shell assembly 1, allowing the inner liner to provide full-area, uniform elastic support to the inner walls of the first shell 11 and the second shell 12. During assembly and use, the soft inner liner assembly 2 continuously applies inward uniform support to the first shell 11 and the second shell 12 through its own elastic restoring force, thereby maintaining the shape regularity of the shells and reducing deformation such as warping, denting, and twisting. Simultaneously, it ensures that the non-recessed planar mating surfaces of the two shells remain flat, aligned, and fitted, guaranteeing overall consistency after the lid is closed.

[0026] The hinge assembly 3 is a rotating connection structure connecting the first housing 11 and the second housing 12, with its two ends fixedly connected to corresponding positions of the first housing 11 and the second housing 12. The hinge assembly 3 adopts a cross four-bar linkage mechanism, which consists of two sets of mutually cross-arranged connecting rods, a rotating shaft, and a connecting seat. The assembly is assembled at the corresponding connection positions of the first housing 11 and the second housing 12. The two sets of connecting rods are hinged to each other through the rotating shaft, forming a linkage structure that can swing synchronously and limit movement.

[0027] During the rotation of the first housing 11 from a closed state to an open state relative to the second housing 12, the two sets of cross linkages swing synchronously along a preset trajectory, smoothly unfolding the first housing 11 outwards until the opening angle of the first housing 11 relative to the second housing 12 reaches 180 degrees. At this point, the first housing 11 is in a fully unfolded state. In the fully unfolded position, the outer surface of the first housing 11 and the mounting plane of the second housing 12 are flush and aligned, without any warping, protrusions, or angles, making the terminal as a whole flat and flush, which is convenient for wall mounting, placement against a wall, or use against a fixed surface. At the same time, it increases the opening of the internal opening, making it easier to put in and take out items, and the structure is stable and not easy to shake after unfolding.

[0028] In this embodiment, the first shell 11 and the second shell 12 adopt a non-stop planar joint surface, and together with the soft inner liner component 2 which is interference-filled into the inner cavity of the outer shell, an integrated soft and hard composite support structure is formed, which eliminates the problems of easy deformation during injection molding and difficulty in alignment when closing the lid caused by the traditional stop structure. The soft inner liner relies on its own elastic support force to continuously maintain the shape accuracy of the first shell 11 and the second shell 12 and the flat alignment of the joint surface. The structure can be stabilized without relying on thickening the shell or adding rigid reinforcing ribs, which effectively reduces material costs and the weight of the whole machine. At the same time, the hinge component 3 connecting the two shells is used for opening and closing, which effectively solves the problems of deformation and misalignment that have long existed in the shells of traditional intelligent logistics terminals.

[0029] Please see Figure 1 The following is a detailed description of the flexible storage bag 121, the fixing strip 122, the locking component 123, and the latching component 124: In an optional embodiment, the rigid housing assembly 1 further includes a flexible storage bag 121 and a fixing strip 122, wherein the flexible storage bag 121 is fixed to the bottom of the rigid housing assembly 1 by the fixing strip 122.

[0030] In an optional embodiment, the flexible storage bag 121 is provided with a locking component 123; The rigid housing assembly 1 is provided with a latching component 124 that cooperates with the locking component 123. The latching component 124 includes a driving unit and a reset component, and the driving unit and the reset component are connected in a transmission manner. The drive unit is used to overcome the elastic force of the reset member to drive the latch component 124 to release the locking component 123. The reset member is used to restore the latch component 124 to the locked state when the drive unit stops driving.

[0031] In an optional embodiment, when the flexible storage bag 121 is in a closed state and the locking component 123 and the latching component 124 are locked together, the flexible storage bag 121 and the rigid outer shell assembly 1 are locked together.

[0032] In the above embodiments, the rigid outer shell assembly 1 also includes a flexible storage bag 121 and a fixing strip 122. The flexible storage bag 121 can be made of high-density Oxford cloth or other wear-resistant flexible materials, and its opening edge is fixed to the bottom of the rigid outer shell assembly 1 by the fixing strip 122, thereby forming a flexible storage space inside the box for accommodating items to be stored. This fixing method ensures that the flexible storage bag 121 remains stable during long-term use and is not easily detached.

[0033] Furthermore, the flexible storage bag 121 is provided with a locking component 123, which can be a zipper pull made of a special metal part, with a barbed groove or other form of locking structure at its end. Correspondingly, the rigid outer shell assembly 1 is provided with a locking component 124 that cooperates with the locking component 123. When the user puts an item into the flexible storage bag 121 and zips it up, the zipper pull is pushed into the slot provided at the bottom of the rigid outer shell assembly 1, and the locking component 124 locks the zipper pull in place.

[0034] Specifically, the locking component 124 includes a drive unit and a reset element, with the drive unit and reset element being drive-connected. The drive unit can be a shape memory alloy drive unit, such as a spring; the reset element can be a slider or lever structure, and is equipped with a reset spring. The transmission relationship between the drive unit and the reset element is configured such that the drive unit overcomes the elastic force of the reset element to drive the locking component 124 to release the locking component 123, and the reset element restores the locking component 124 to the locked state when the drive unit stops driving.

[0035] When the user pushes the zipper head into the slot, the reset member inside the locking component 124, under the action of the reset spring, engages with the barb groove at the end of the zipper head, achieving a locking engagement between the locking component 123 and the locking component 124. At this time, the flexible storage bag 121 is locked inside the rigid outer shell assembly 1, achieving an integrated locking state for the bag and case. When the user issues an unlocking command electronically, the drive unit is energized and actuates, overcoming the spring force of the reset member to drive the locking component 124 to move, causing the reset member to disengage from the barb groove of the zipper head, thereby releasing the locking component 123. At this time, the zipper head automatically pops out of the slot under the action of the spring force, allowing the user to unzip and retrieve the items.

[0036] The driving unit of the locking component 124 can be driven by shape memory alloy (SMA), and the terminal is equipped with a control circuit board and a temperature sensor. The temperature sensor is located inside the terminal and is used to monitor the ambient temperature in real time. When the temperature sensor detects that the ambient temperature is lower than a preset threshold, the control circuit identifies the low-temperature condition and automatically switches to the low-temperature driving mode. In this mode, the control circuit outputs a high duty cycle pulse current to the driving unit. Specifically, the duration of the pulse current is less than 1 second, and the instantaneous current can reach more than 3A, which can heat the SMA wire to the phase transition temperature in a very short time, causing it to overcome the damping in the low-temperature environment and generate a contraction action, thereby driving the reset member to move and release the locking component.

[0037] Please see Figure 1 The mechanical emergency lock hole 125 is described in detail below: In an optional embodiment, the bottom of the rigid housing assembly 1 is provided with a mechanical emergency lock hole 125; The mechanical emergency lock hole 125 is provided with a lock cylinder fork, which is connected to the reset member for driving the reset member to move by a special key to release the locking component 123.

[0038] In this embodiment, when the drive unit fails to work properly due to battery depletion, control circuit failure, or drive unit damage, the user can insert a special short-handle key into the mechanical emergency lock hole 125 and rotate it. The key drives the lock cylinder fork to rotate, and the lock cylinder fork directly drives the reset member to move, causing the reset member to disengage from the locking component 123's engagement structure, thereby achieving emergency unlocking in a purely mechanical manner.

[0039] Please see Figure 1 The emergency charging interface 126 will be described in detail below: In an optional embodiment, an emergency charging interface 126 is provided on the top of the rigid housing assembly 1; The emergency charging interface 126 is electrically connected to the drive unit and is used to provide emergency power to the locking component 124 when there is no internal battery or the battery is depleted.

[0040] In this embodiment, the emergency charging interface 126 is electrically connected to the drive unit within the latch component 124. Specifically, the power input terminal of the emergency charging interface 126 bypasses the battery charging management circuit and is directly connected to the power input terminal of the drive unit. The emergency charging interface 126 is used to provide emergency power to the latch component 124 when there is no internal battery or the battery is depleted. When the internal battery of the intelligent logistics terminal is depleted, damaged, or its voltage drops significantly due to low temperature, and cannot provide normal operating current to the drive unit, the user can insert an external power source into the emergency charging interface 126 via a connecting cable. The external power source directly supplies power to the drive unit. When the user issues an unlocking command via a mobile app or by scanning a code, the control circuit outputs a drive signal to the drive unit based on the external power source's connection status. Because the emergency charging interface 126 is directly electrically connected to the drive unit, even if the internal battery cannot provide power, the drive unit can still obtain sufficient power to complete the action, thereby driving the latch component 124 to release the locking component 123, achieving electronic unlocking.

[0041] Please see Figure 2 , Figure 2 The following is a detailed description of the external structure of the intelligent logistics terminal based on a soft-hard composite support structure provided in this application, shown in the QR code scanning area 111: In an optional embodiment, the outer wall of the rigid housing assembly 1 is provided with a QR code scanning area 111, which is used for identification of pickup information to trigger the locking component 124 to unlock.

[0042] In this embodiment, when a user picks up their item, they can scan the QR code in the QR code scanning area 111 using a mobile terminal such as a smartphone. The mobile terminal then sends the scanned item pickup information to a cloud server or a local control system. After verifying that the pickup information is correct, the control system generates an unlocking signal and sends it to the drive unit of the locking component 124, triggering the locking component 124 to unlock, allowing the first housing 11 to open relative to the second housing 12.

[0043] Please see Figure 1 The following is a detailed explanation of the imported corner structure 127: In an optional embodiment, an inlet corner structure 127 is provided at the edge of the mating surface of the first housing 11 and the second housing 12. The inlet size of the inlet corner structure 127 is 3.0mm~4.0mm. The inlet corner structure 127 is configured to guide the first housing 11 to slide into alignment relative to the second housing 12 during the closing process.

[0044] In this embodiment, the guide angle structure 127 is disposed at the edge of the mating surface of the first housing 11 and / or the second housing 12, and is continuously or intermittently distributed along the circumference of the mating surface. The guide angle structure 127 has a guide dimension of 3.0mm to 4.0mm, and the guide angle is a bevel or arc surface structure, with the inclination angle matching the depth to form a guide bevel. The guide angle structure 127 is configured to guide the first housing 11 to slide into alignment relative to the second housing 12 during the closing process. Specifically, when the first housing 11 and the second housing 12 are fastened together, the guide angle structure 127 first contacts, and uses its beveled guiding effect to gradually guide the relative position of the two housings to the correct alignment state. This guiding process can effectively overcome the assembly resistance caused by the interference fit between the soft inner liner assembly 2 and the hard outer shell assembly 1, making the closing operation smoother, while ensuring that the mating surfaces of the two housings are aligned in the final closed state.

[0045] Please see Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the back structure and the structure of the back plate 128 of the intelligent logistics terminal based on a soft and hard composite support structure according to this application. Figure 4 This is a structural diagram of the wall-mounted installation state of the intelligent logistics terminal based on a soft and hard composite support structure according to this application.

[0046] In an optional embodiment, the second housing 12 is provided with a back plate 128, and the back plate 128 is provided with a buckle; the second housing 12 is detachably connected to the back plate 128 via the buckle.

[0047] In this embodiment, a back plate 128 is disposed on the back of the second housing 12 for mounting the intelligent logistics terminal on a wall, bracket, or other fixed object. The back plate 128 is an independent component with snap fasteners, which can be elastic snap fasteners, hook-shaped snap fasteners, or other detachable connection structures. The second housing 12 is detachably connected to the back plate 128 via snap fasteners. The back of the second housing 12 has a slot or interface that matches the snap fasteners. During installation, the second housing 12 is pushed in from top to bottom or from front to back to engage the snap fasteners with the interface, thus securing it. During disassembly, the snap fasteners are disengaged from the interface by pressing or pulling, allowing the second housing 12 to be removed from the back plate 128. By providing a detachable connection structure between the back plate 128 and the snap fasteners, rapid installation and disassembly of the intelligent logistics terminal are achieved.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application.
