Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, and more specifically, to a non-powered automatic winding reel device. Background Technology

[0002] In the field of logistics automation, signal transmission between mobile logistics platforms (such as AGVs and automated guided vehicles) and external signal control terminals typically relies on wired connections (such as cables) or wireless connections (such as Wi-Fi and Bluetooth). However, these technologies have the following limitations:

[0003] When logistics platforms move, cables are prone to tangling or knotting due to changes in length, leading to signal interruptions or equipment damage. Frequent cable management and replacement increase maintenance costs.

[0004] Traditional cable reels are only used for winding and unwinding cables and cannot transmit signals. They require external power to drive their rotation, increasing system complexity and energy consumption. Powered cable reels are expensive, requiring motors, controllers, and other components, leading to increased equipment costs. Furthermore, the power system is prone to failure and difficult to maintain.

[0005] The invention patent with application number 202411634467.1 discloses an elastic winding mechanism and a convenient connector. Although it solves the cable storage problem to some extent, it still cannot meet the requirements for stable signal transmission between the mobile logistics platform and the external signal control terminal in the context of logistics automation. Moreover, the device has a complex structure and is not suitable for the frequent moving operation environment of logistics equipment.

[0006] With the increasing demands for equipment reliability, flexibility, and cost control in logistics automation, the market urgently needs an automatic cable reel device that is powerless, maintenance-free, and has stable signal transmission. Utility Model Content

[0007] The purpose of this invention is to provide a non-powered automatic winding reel device to solve the problems mentioned in the background art, such as the inability to meet the requirement of stable signal transmission between the mobile logistics platform and the external signal control terminal, and the complex structure of the device, which is not suitable for the frequent moving operation environment of logistics equipment.

[0008] To achieve the above objectives, this utility model provides a non-powered automatic cable reel device, including a cable reel housing, wherein a flat cable is wound around the cable reel inside the cable reel housing;

[0009] The inside of the reel housing is equipped with a spring for controlling the retraction or release of the flat cable. A conductive slip ring for signal transmission is installed on one side of the reel housing. One end of the conductive slip ring is connected to the flat cable, and the other end is connected to an external signal control terminal.

[0010] This design utilizes a spring-loaded mechanism to automatically retract and release the flat cable, eliminating the need for an external power source and reducing energy consumption and costs. A conductive slip ring facilitates signal transmission between the rotating and stationary components, avoiding interference issues associated with wireless connections.

[0011] Preferably, the reel housing has pre-drilled screw holes for installation on logistics equipment.

[0012] This feature facilitates quick installation on logistics equipment and adapts to different installation environments.

[0013] Preferably, one end of the flat cable extends from the outer wall of the reel housing and is connected to the moving logistics platform, while the other end is connected to the conductive slip ring via the reel. The conductive slip ring transmits signals from the flat cable to an external signal control terminal, or transmits signals from the external signal control terminal to the flat cable.

[0014] This physical contact transmission method using conductive slip rings reduces the impact of electromagnetic interference on signal quality and improves the reliability of signal transmission.

[0015] Preferably, the outer edge of the winding reel is provided with a groove for winding the flat cable. One end of the flat cable is fixed to the winding reel, and the other end extends to the outside of the reel housing for connection with a mobile logistics platform.

[0016] This recessed design ensures that flat cables are wound in an orderly manner, preventing cables from crossing or coming off, and reducing the risk of cable wear and breakage.

[0017] Preferably, a limiting cover for limiting the flat cable is installed on one side of the winding reel.

[0018] This feature includes a limit cover to prevent flat cables from deviating from the track during winding, further ensuring the orderly management of cables.

[0019] Preferably, the inner end of the spring is fixedly connected to the central rod inside the housing of the winding spool, and the outer end of the spring is fixedly connected to the winding spool of the flat cable.

[0020] This feature provides a constant recovery force with a spring, preventing the cable from becoming excessively slack or taut, and reducing the risk of cable wear and breakage.

[0021] Preferably, the conductive slip ring consists of a stator portion and a rotor portion, the stator portion being fixed inside the winding reel housing, and the rotor portion rotating synchronously with the winding reel.

[0022] This setting ensures the synchronous rotation of the stator and rotor, guaranteeing the continuity and stability of signal transmission.

[0023] Preferably, the flat cable has a width of ≤16mm and a length of 750mm.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] This non-powered automatic cable reel device utilizes the elastic potential energy of a spring to automatically retract and release flat cables, eliminating the need for an external power source and significantly reducing energy consumption and operating costs. Compared to powered cable reels, it reduces the number of components such as motors and controllers, lowering equipment complexity and manufacturing costs.

[0026] Integrated conductive slip rings enable signal transmission between rotating and stationary components, ensuring stable signal transmission between the mobile logistics platform and external control terminals, and avoiding interference issues associated with wireless connections. The physical contact transmission method of the conductive slip rings reduces the impact of electromagnetic interference on signal quality, thus improving the reliability of signal transmission.

[0027] The combination of a spring-loaded clockwork spring and a conductive slip ring reduces potential points of failure in the power system and lowers maintenance frequency. The conductive brushes or contacts of the slip ring are made of wear-resistant materials, extending their service life and reducing the risk of signal interruption due to wear.

[0028] The cable reel housing integrates components such as the spring, conductive slip ring, and winding spool, resulting in a compact design that saves installation space. Pre-drilled holes in the reel housing facilitate quick installation on logistics equipment, adapting to various installation environments. The spring provides constant recovery force, preventing excessive slack or tension in the cable and reducing the risk of cable wear and breakage. The limiting cover and groove design on the outer side of the winding spool ensure orderly cable winding, preventing cable crossing or detachment. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides a non-powered automatic winding reel device, such as... Figures 1-3 As shown, the device includes a reel housing 1, inside which a flat cable 4 is wound via a reel 5; inside the reel housing 1, a spring 2 for controlling the retraction or release of the flat cable 1 is installed; a conductive slip ring 3 for signal transmission is installed on one side of the reel housing 1, one end of the conductive slip ring 3 is connected to the flat cable 4, and the other end is connected to an external signal control terminal.

[0036] The flat cable 4 is automatically retracted and released using a spring-loaded mechanism 2, eliminating the need for an external power source and reducing energy consumption and costs. A conductive slip ring 3 enables signal transmission between the rotating winding reel 5 and the fixed winding reel housing 1, avoiding interference issues associated with wireless connections.

[0037] like Figure 1 As shown, the cable reel housing 1 has pre-drilled screw holes 11 for installation on logistics equipment.

[0038] The screw hole 11 on the cable reel housing 1 facilitates quick installation on logistics equipment such as AGV carts, adapting to different installation environments.

[0039] Furthermore, one end of the flat cable 1 extends from the outer wall of the reel housing 1 and connects to the moving logistics platform, while the other end connects to the conductive slip ring 3 via the reel 5. The conductive slip ring 3 transmits signals from the flat cable 4 to an external signal control terminal, or transmits signals from the external signal control terminal to the flat cable 4. This physical contact transmission method using the conductive slip ring 3 reduces the impact of electromagnetic interference on signal quality and improves the reliability of signal transmission.

[0040] like Figure 1 As shown, the outer edge of the winding reel 5 is provided with a groove 51 for winding the flat cable 4. One end of the flat cable 4 is fixed on the winding reel 5, and the other end extends to the outside of the reel housing 1 for connection with the mobile logistics platform.

[0041] The groove 51 design ensures that the flat cable 4 is wound in an orderly manner, preventing the cable from crossing or coming off, and reducing the risk of cable wear and breakage.

[0042] like Figure 1As shown, a limiting cover plate 52 for limiting the flat cable 4 is installed on one side of the winding reel 5.

[0043] The limiting cover plate 52 prevents the flat cable 4 from deviating from the track during the winding process, further ensuring the orderly management of the cable.

[0044] like Figure 2 As shown, the inner end 21 of the spring 2 is fixedly connected to the central rod 12 inside the winding reel housing 1, and the outer end 22 of the spring 2 is fixedly connected to the winding reel 5 of the flat cable 4.

[0045] The constant recovery force provided by the spring 2 prevents the cable from being excessively slack or tensile, reducing the risk of cable wear and breakage.

[0046] like Figure 3 As shown, the conductive slip ring 3 consists of a stator part 31 and a rotor part 32. The stator part 31 is fixed inside the winding reel housing 1, and the rotor part 32 rotates synchronously with the winding reel 5.

[0047] The continuity and stability of signal transmission are ensured by the synchronous rotation of the stator section 31 and the rotor section 32.

[0048] Furthermore, the flat cable 4 has a width of ≤16mm and a length of 750mm, which meets the signal transmission requirements of different logistics platforms and improves the versatility of the equipment.

[0049] In use, the non-powered automatic cable reel device of this utility model first pulls out the flat cable 4 when the logistics platform moves, the winding reel 5 rotates, and the outer end 22 of the spring 2 rotates with the winding reel 5, storing energy. When the logistics platform stops moving, the spring 2 releases the stored energy, driving the winding reel 5 to rotate in the opposite direction, and the flat cable 4 is wound back into the groove 51 in an orderly manner, with the limiting cover plate 52 preventing the cable from deviating.

[0050] The spring 2 enables automatic retraction and release without the need for an external power source, reducing energy consumption and costs. The spring 2 provides a constant retraction force, preventing the cable from becoming excessively slack or tensile, and reducing the risk of wear and breakage. The conductive slip ring 3 consists of a stator part 31 and a rotor part 32. The stator part 31 is fixed inside the winding reel housing 1, and the rotor part 32 rotates synchronously with the winding reel 5.

[0051] One end of the flat cable 4 is fixed to the winding reel 5, and the other end extends to the outside of the winding reel housing 1 and connects to the logistics platform.

[0052] The logistics platform signal is transmitted to the rotor portion 32 of the conductive slip ring 3 via the flat cable 4. The rotor portion 32 and the stator portion 31 transmit signals through physical contact, and the stator portion 31 transmits the signals to the external signal control terminal. The signals from the external signal control terminal are transmitted back to the logistics platform, achieving bidirectional signal transmission. The physical contact transmission method of the conductive slip ring 3 reduces the impact of electromagnetic interference on signal quality and improves the reliability of signal transmission. The stator portion 31 and the rotor portion 32 rotate synchronously, ensuring the continuity and stability of signal transmission.

[0053] Finally, it should be noted that the electronic components in the above-mentioned components in this embodiment are all general standard parts or parts known to those skilled in the art.
