Description

Technical Field

[0001] This utility model relates to the field of modular control harness technology for intelligent logistics cabinets, specifically a modular control harness structure for intelligent logistics cabinets. Background Technology

[0002] IoT-based devices that can identify, temporarily store, monitor, and manage items meet the current development needs of the logistics industry, solve the urgent problem of the last mile of logistics delivery, and control the overall equipment that provides services to a certain load source group, such as relay lines, switching devices, and control systems. In existing technologies, wire harnesses tend to stack and tangle on the wire harness reel. Traditional devices may experience jamming due to messy wiring. Tools are required to splice and securely connect the boxes, and the boxes are usually uneven. To address these issues, we propose a modular control wire harness structure for smart logistics cabinets. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a modular control wire harness structure for intelligent logistics cabinets. It can realize dual control of instant cable length fixing and autonomous cable arrangement during the winding and unwinding process, so that the wire harness forms a uniform winding without stacking on the wire harness reel, realizing tool-free rapid splicing and tensile-resistant stable connection between cabinets. At the same time, the hidden design maintains the flatness of the cabinet appearance, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular control harness structure for intelligent logistics cabinets, including a protective box, a harness control component, a transmission component, and a modular splicing component; Protective box: The inside is equipped with wire harness control components, transmission components and module splicing components; The wire harness control assembly includes a wire harness reel, a wire clamping groove, a ratchet, a self-locking electric telescopic rod, and a motor. The wire harness reel is rotatably connected to the lower inner part of the protective box. The wire harness reel has a wire clamping groove in its center. The motor is located at the lower inner part of the protective box. The output shaft of the motor is fixedly connected to the ratchet. The upper end of the ratchet is rotatably connected to the wire harness reel. The self-locking electric telescopic rod is fixedly connected to the lower inner part of the protective box. The movable end of the self-locking electric telescopic rod engages with the ratchet.

[0005] The protective box serves as the main frame, integrating various components. The cable tray is connected to the lower part of the box's interior. A motor drives a ratchet to rotate the cable tray. The movable end of the self-locking electric telescopic rod can engage with the ratchet's tooth groove. During use, the self-locking electric telescopic rod retracts, pulling the cable tray to rotate. The self-locking electric telescopic rod extends and engages the ratchet to fix the cable length. When it is necessary to retract the cable, the motor drives the ratchet to rotate, simultaneously retracting the cable tray. The self-locking electric telescopic rod extends and engages the ratchet to fix the cable length, allowing the motor to quickly retract the cable.

[0006] Furthermore, the wiring harness control assembly also includes a limiting frame, a sliding frame, and a threaded rod. A limiting frame is provided on the front right side of the protective box, and another limiting frame is provided on the rear left side of the protective box. A sliding frame is slidably connected to the inside of each limiting frame, and a threaded rod is rotatably connected to the inside of each limiting frame. The threaded rod is threadedly connected to the sliding frame.

[0007] The limiting frame is symmetrically located on the front and rear sides of the housing. The sliding frame is driven to move along the guide rail by the threaded rod. The rotation of the threaded rod is converted into linear motion of the sliding frame. The motor drives the wire to take in the wire. During the take-in process, the threaded rod is rotated by the transmission component, which makes the sliding frame move linearly, ensuring that the wire harness can be evenly wound on the wire harness reel during the take-in process.

[0008] Furthermore, the transmission assembly includes a pinion, a large gear, a first intermediate gear, a second intermediate gear, a first chain, and a second chain. The pinion is fixedly connected to the lower rotation center of the ratchet, and the large gear is rotatably connected to the lower inner side of the protective box. Two first intermediate gears are fixedly connected to the upper and lower rotation centers of the large gear. The second intermediate gear is fixedly connected to the outer side of the threaded rod. The pinion and the large gear are connected by the first chain, and the first intermediate gear and the corresponding second intermediate gear are connected by the second chain.

[0009] The pinion is fixed coaxially with the ratchet, and the large gear receives power through chain one. Gear one and medium gear two are linked by chain two and threaded rod, and the power is transmitted through gears and racks. At the same time, the gear ratio ensures accurate guidance.

[0010] Furthermore, the module splicing assembly includes a limiting groove, a dovetail slider, and a circular through hole. The right end of the protective box has a limiting groove, and one end of the dovetail slider is slidably connected to the inner side of the limiting groove. The inner side of the dovetail slider has three circular through holes.

[0011] The limiting groove and the dovetail slider slide together, allowing the dovetail slider to be hidden when not in use. The dovetail structure has an anti-detachment design, and the multi-hole circular through hole ensures connection stability.

[0012] Furthermore, the modular splicing assembly also includes a second limiting groove, a sliding block, inserts, a dovetail-shaped slide groove, a second circular through hole, a bidirectional threaded rod, and a rotating handle. A dovetail-shaped slide groove is provided in the middle of the left end of the protective box. Three second circular through holes are provided on the inner side of the dovetail-shaped slide groove. Two second limiting grooves are provided at the front and rear of the left end of the protective box. A sliding block is slidably connected to the inner side of the second limiting groove. Three inserts are fixedly connected to the inner side of the sliding block. The dovetail-shaped slider is slidably connected to the dovetail-shaped slide groove. A bidirectional threaded rod is rotatably connected to the inner side of the protective box. The bidirectional threaded rod is threadedly connected to the sliding block. A rotating handle is fixedly connected to the front end of the bidirectional threaded rod. The inserts are slidably connected to the second circular through hole.

[0013] The dovetail-shaped slider and the dovetail-shaped groove are slidably connected. The rotating handle drives the bidirectional threaded rod to make the sliding blocks move towards each other. The insert is inserted into the second and first circular through holes to complete the module locking. The threaded transmission is converted into the bidirectional synchronous action of the insertion mechanism. The mechanical linkage ensures the consistency of the insertion, and the bidirectional thread improves the assembly efficiency.

[0014] Furthermore, it also includes support legs, wiring harness and sealing cover. Four support legs are fixedly connected to the four corners of the lower end of the protective box. Anti-slip pads are provided at the lower end of the support legs. The middle part of the wiring harness is engaged with the wire clamping groove. A sealing cover is provided at the upper end of the protective box.

[0015] The support legs are fixed to the four corners of the enclosure with bolts, the wire harness is embedded in the middle of the wire clamping groove, the anti-slip pad absorbs equipment vibration, the sealing cover seals the internal components, the integrated protection design extends service life, and the quick-release structure facilitates maintenance.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This modular control harness structure for intelligent logistics cabinets has the following advantages: 1. The modular control harness structure used in this intelligent logistics cabinet enables dual control of real-time cable length fixing and autonomous cable routing during the winding and unwinding process. The ratchet mechanism, together with the self-locking electric telescopic rod, forms a physical hard lock, ensuring absolute anti-rebound in the stretched state of the harness. The synchronously operating gear chain transmission group converts the winding torque into precise rotation of the bidirectional threaded rod, driving the sliding frame to reciprocate along the limit frame, so that the harness forms a uniform, non-overlapping winding on the cable tray, completely eliminating the risk of jamming caused by messy cable routing in traditional devices.

[0017] 2. The modular control harness structure used in this intelligent logistics cabinet enables tool-free rapid splicing and tensile-resistant stable connection between cabinets. The dovetail-shaped slider hidden in the limiting groove can slide out and accurately embed into the adjacent cabinet's sliding groove to form initial positioning. The single-axis bidirectional threaded rod mechanism transforms the rotational motion into a three-strip synchronous through-action, allowing the strips to simultaneously pierce the machine's circular through-hole two and the docking cabinet's circular through-hole one, forming a through-type mechanical interlock. The dovetail guide rail bears the longitudinal shearing force, and the strips resist the lateral pull-out force. This double protection ensures the structural integrity of the expansion module in a vibration environment, while the hidden design maintains the flatness of the cabinet's appearance.

A dovetail groove 57 is provided in the middle of the left end of the protective box 1. Three circular through holes 58 are provided on the inner side of the dovetail groove 57. Two limiting grooves 54 are provided at the front and rear of the left end of the protective box 1. A sliding block 55 is slidably connected to the inner side of the limiting groove 54.

[0033] The working principle of the modular control wire harness structure for intelligent logistics cabinets provided by this utility model is as follows: First, the self-locking electric telescopic rod 34 is retracted, causing its movable end to disengage from the tooth groove of the ratchet 33, thus releasing the lock on the wire harness 31; then, the wire harness 6 is pulled, and the middle part of the wire harness 6 is locked in the wire-locking groove 32 of the wire harness 31. During the pulling process, the wire harness 31 is rotated to release the cable of the required length; after reaching the required length, the self-locking electric telescopic rod 34 is extended, causing its movable end to engage with the tooth groove of the ratchet 33, locking the ratchet 33 and the wire harness 31 connected to it, thus fixing the cable length. When it is necessary to retract the cable, the motor 35 is started. The motor 35 drives the ratchet 33 to rotate and drives the wire harness 31 to rotate to retract the cable; during this retraction process, the small gear 41 coaxial below the ratchet 33 drives the large gear 42 to rotate through the chain 45, and the middle gears 43 at both ends of the large gear 42 are then driven by the chain 46. The second gear 44 on the moving threaded rod 38 rotates, causing the threaded rod 38 to rotate and drive the sliding frame 37 to move linearly within the limiting frame 36. This guides the wire harness 6 to be evenly wound onto the wire harness reel 31. The process of pulling the wire harness 6 is completely opposite to the rotation direction of the gear in the transmission assembly during the wire take-up process. After take-up, the self-locking electric telescopic rod 34 remains extended, locking the ratchet 33 to secure the cable. If modular expansion is required, the dovetail slider 52 hidden on the right side of the adjacent protective box 1 is slid into the dovetail groove 57 on the left side of this box along the dovetail groove 57, aligning with the first circular through hole 53 and the second circular through hole 58. Then, the rotating handle 510 is rotated to drive the bidirectional threaded rod 59 to rotate, causing the two sliding blocks 55 to move towards each other within the limiting groove 54. This allows the inserts 56 on the sliding blocks 55 to be inserted simultaneously into the first circular through hole 53 of the docking box and the second circular through hole 58 of this box, achieving mechanical locking of the two modules. The entire structure is securely placed by the support legs 2, and the sealing cover 7 provides protection.

[0034] It is worth noting that, in the above embodiments, the input terminals of the self-locking electric telescopic rod 34 and the motor 35 are electrically connected to the output terminal of an external power supply through an external PLC controller. The motor 35 and the limit are servo motors, and the external PLC controller controls the operation of the self-locking electric telescopic rod 34 and the motor 35 using methods commonly used in the prior art.
