Description

Technical Field

[0001] This application belongs to the field of 3D scanning technology, specifically relating to a long-distance 3D scanning cable assembly. Background Technology

[0002] 3D scanning technology is a high-tech field integrating optics, mechanics, electronics, and computer technology. It is primarily used to scan the spatial shape, structure, and color of objects to obtain their surface spatial coordinates. Its significance lies in its ability to convert the three-dimensional information of physical objects into digital signals that can be directly processed by computers, providing a convenient and efficient means for digitizing physical objects. With its advantages of non-contact measurement, high speed, and high accuracy, and the ability to directly interface with various software, 3D scanning technology is highly favored in CAD, CAM, CIMS, and other technological applications. Its application is particularly widespread in the manufacturing industries of developed countries as a rapid 3D measurement device.

[0003] However, from the perspective of equipment, current 3D scanning technology, particularly high-precision 3D laser scanners, is typically large and heavy, resulting in poor portability and difficulty in easily moving them to different sites, which greatly limits the flexibility of on-site use.

[0004] To improve the portability of 3D scanners, the current market commonly uses a USB cable with an additional repeater amplifier. However, this method limits the communication distance to 3-7 meters. For every 3 meters beyond this distance, an additional signal amplifier is required to ensure stable signal transmission and prevent packet loss. When scanning large objects such as vehicles or bridge structures, the limited scanning distance necessitates the use of numerous repeaters and long data cables, significantly increasing costs. Furthermore, the complex cable layout negatively impacts the overall aesthetics. The heavy cables and multiple amplifier stages also severely reduce the cable's maneuverability and mobility during scanning, severely affecting the efficiency and smoothness of the scanning process. Utility Model Content

[0005] To address the shortcomings of the prior art, this application provides a long-distance three-dimensional scanning cable assembly.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0031] Example 1:

[0032] Please see the appendix Figure 1-2 This application discloses a long-distance 3D scanning cable assembly, comprising a signal transmission cable 1 and a power supply cable 2 arranged in parallel. The power supply cable 2 is used to provide a stable power supply for the 3D scanning equipment. The signal transmission cable 1 includes a first cable body 11, a first connector 12, and a second connector 13. The first connector 12 is electrically connected to one end of the first cable body 11, and the second connector 13 is electrically connected to the other end of the first cable body 11. The first connector 12 is used to connect to a computer connector, and the second connector 13 is used to connect to a 3D scanner connector. The first cable body 11 includes four pairs of independently insulated twisted pairs 111, each twisted pair including two twisted first conductors 1111. The first cable body 11 is used to transmit differential Ethernet signals.

[0033] Specifically, signal transmission cable 1 can be implemented using Cat6e Ethernet cable, forming a differential signal transmission channel through four pairs of twisted pairs 111 to suppress common-mode interference. Power supply cable 2 refers to a power transmission unit physically separated from the signal cable, carrying current through an independent conductor to avoid electromagnetic coupling interference with signal transmission.

[0034] In this embodiment, the long-distance 3D scanning cable assembly features a dual-channel architecture with signal transmission cable 1 and power supply cable 2 arranged in parallel. The signal channel transmits differential Ethernet signals via four pairs of twisted-pair cables 111. Each pair of twisted-pair cables 111 carries signals with opposite phases, and common-mode noise is eliminated at the receiving end through differential calculation. Power supply cable 2 transmits power independently, avoiding electromagnetic interference from high current to nearby signal cables. The first connector 12 matches the standard interface on the computer, and the second connector 13 adapts to the scanning equipment interface, forming an end-to-end direct link. The four pairs of twisted-pair cables 111 maintain signal integrity through balanced transmission characteristics during long-distance transmission, achieving stable communication without the need for repeater amplification.

[0035] This solution achieves stable long-distance signal transmission for 3D scanning equipment through differential signal transmission and independent power supply design, avoiding the cost and complexity of repeater amplifiers. It not only effectively simplifies the cable structure and reduces deployment costs but also correspondingly improves transmission rate and distance. The differential signal transmission mechanism effectively suppresses electromagnetic interference, ensuring the integrity and real-time performance of scan data over distances of hundreds of meters, meeting the needs of large object scanning operations. Furthermore, the parallel dual-cable structure reduces overall weight and improves the flexibility and convenience of cable movement, thereby effectively enhancing the efficiency and smoothness of scanning operations.

[0036] In some embodiments, the power supply cable 2 includes a second cable body 21, a power input connector 22, and a power output connector 23. The power input connector 22 is electrically connected to one end of the second cable body 21, and the power output connector 23 is electrically connected to the other end of the second cable body 21. The power input connector 22 is opposite to the first connector 12, and the power output connector 23 is opposite to the second connector 13.

[0037] In this embodiment, by designing the power supply cable 2 and the signal transmission cable 1 as a parallel integrated component, the power transmission path and the signal transmission path are completely separated in physical space. Furthermore, by aligning them, the power input connector 22 and the first connector 12 are on the same side, and the power output connector 23 and the second connector 13 are on the same side. This improves the ease of connection for operators during the plugging process, effectively reduces the connection error rate, and facilitates cable organization, minimizing clutter.

[0038] In addition, the independently designed second cable body 21 adopts a multi-conductor parallel structure, which reduces line impedance and heat generation during high current transmission compared to the single-core power supply cable 2, while maintaining the same cross-sectional area. The independent power supply cable 2 structure avoids the influence of electromagnetic noise generated during power transmission on differential signals, ensuring the integrity of 3D scanning data during long-distance transmission.

[0039] In some embodiments, the second cable body 21 includes two independently insulated second conductors 211 and third conductors 212.

[0040] Specifically, the combined structure of the second conductor 211 and the third conductor 212 forms a complementary current-carrying mechanism in the power supply cable 2. The second conductor 211 reduces the overall weight of the cable through a small cross-section design, while the third conductor 212 increases its current-carrying capacity through a large cross-section design. The two second conductors 211 form a parallel circuit, ensuring uniform current distribution during low-power signal transmission; the two third conductors 212 form a redundant path, enabling load sharing under high-current conditions. Independent insulation layers eliminate parasitic capacitance effects between conductors, preventing high-frequency interference from coupling into the power supply circuit. The dual-conductor layout doubles the total effective cross-sectional area, reducing voltage drop caused by DC resistance, while also reducing the temperature rise of individual conductors through current shunting. This structure improves voltage stability during long-distance power transmission while maintaining the cable's bending performance.

[0041] Through the above technical solution, this application effectively suppresses voltage attenuation during long-distance power transmission, enabling the power supply cable 2 to maintain stable output voltage within a 10-meter range without the need for a repeater. The multi-conductor structure allows the cable to adapt to power fluctuations during the movement of the 3D scanning equipment, preventing equipment restarts or data interruptions caused by sudden current surges. The synergistic effect of thick and thin conductors reduces cable weight while meeting the dual requirements of power supply reliability and portability for the 3D scanner.

[0042] In some embodiments, the cross-sectional area of ​​the first conductor 1111 is any value between 0.1257 mm² and 0.1281 mm². Preferably, the first conductor 1111 is a conductor formed by stranding 28 copper wires with a diameter of 0.08 mm, conforming to the 26 AWG wire gauge standard.

[0043] Specifically, this cross-sectional area range is determined by precisely calculating the current-carrying capacity of the conductor cross-section and the signal transmission requirements. When the conductor cross-sectional area is too small, the increased resistance leads to accelerated signal attenuation; when the cross-sectional area is too large, the cable rigidity increases, affecting wiring flexibility. By controlling the cross-sectional area within a specific range, the low impedance characteristics required for differential Ethernet signal transmission are met, while avoiding the loss of bending performance due to excessive conductor thickness. The conductor uses a multi-stranded structure of fine copper wires, which enhances bending resistance while maintaining the total cross-sectional area, ensuring that the signal maintains waveform integrity during long-distance transmission.

[0044] Through the above technical solution, this application effectively suppresses energy loss during long-distance signal transmission, solves the signal attenuation problem caused by improper conductor cross-sectional area, ensures that differential Ethernet signals can maintain stable waveform characteristics and data integrity over a transmission distance of more than 20 meters, and at the same time enables the cable to have good draggability to adapt to the needs of on-site mobile scanning.

[0045] In some embodiments, the cross-sectional area of ​​the second conductor 211 is any value between 0.0788 mm² and 0.0804 mm², meeting the 28 AWG wire gauge standard; the cross-sectional area of ​​the third conductor 212 is any value between 0.5083 mm² and 0.5189 mm², preferably, the third conductor 212 is a conductor formed by stranding 105 copper wires with a diameter of 0.08 mm, meeting the 20 AWG wire gauge standard.

[0046] In this embodiment, the power supply cable 2 is configured with the second conductor 211 and the third conductor 212 in layers, creating independent transmission paths for the low-current and high-current loops. The second conductor 211 uses a smaller cross-sectional area to meet the control signal transmission requirements, while the third conductor 212 uses a larger cross-sectional area to carry the main power supply current. The cross-sectional area ranges of the two conductors correspond to standard wire gauges, allowing for direct selection of industrial standard wires during manufacturing, avoiding increased costs associated with customized production. This configuration allows the power supply cable 2 to maintain flexibility while adapting to the frequent bending scenarios encountered by 3D scanning equipment during mobile operations. Furthermore, by optimizing the cross-sectional area of ​​some conductors to the minimum required value while ensuring total power supply capacity, the overall weight of the cable is effectively reduced.

[0047] Through the above technical solution, this application enables the power supply cable 2 to reduce its diameter to less than 70% of the traditional design while maintaining a 24V / 5A power supply capacity, and allows the power supply distance to be extended to more than 15 meters without the need for repeater equipment. This design solves the problem of low work efficiency caused by the difficulty of dragging cables when scanning large objects, and ensures compatibility with production processes through standardized wire gauge selection.

[0048] In some embodiments, the first connector 12 is an RJ45 crystal head; the second connector 13 is any connector of the M12 series or aviation connector.

[0049] Among them, the RJ45 crystal head refers to an eight-pin modular connector that conforms to the Ethernet communication standard. Specifically, it can be implemented using gold-plated copper alloy contacts and an injection-molded insulating shell. It is used to establish a differential signal transmission channel and is compatible with the standard network interface of a computer. It can be flexibly adapted to different brands depending on the actual situation. The M12 series connector refers to an industrial connector with a circular thread locking structure. Specifically, it can be implemented using a metal shell and an IP67-rated sealing ring to maintain stable electrical contact in vibrating environments. Aviation connectors refer to connectors with quick-connect and self-locking functions. Specifically, it can be implemented using an aluminum alloy shell and a multi-pin foolproof design to prevent accidental dislodgement in high-frequency plugging and unplugging scenarios.

[0050] Specifically, the RJ45 connector reduces the impact of electromagnetic interference on Ethernet communication through differential signal transmission, enabling the signal transmission cable 1 to maintain data integrity over longer distances and avoid communication interruptions due to signal attenuation. The M12 series connectors or aviation connectors, through their mechanical locking structure and protective design, resist external vibration and dust intrusion during the movement of 3D scanning equipment, ensuring the physical connection reliability of the power and signal transmission interfaces in industrial environments. The combined application of these two types of connectors allows the cable assembly to extend communication distances while ensuring signal quality without relying on repeater amplifiers, and the adaptability of the connector structure eliminates the risk of poor contact in complex operating conditions associated with traditional USB interfaces.

[0051] Through the above settings, stable communication without repeaters is achieved for long-distance 3D scanning cable assemblies at distances of over 30 meters, eliminating the cable dragging resistance and layout complexity caused by repeater amplifiers. At the same time, the industrial-grade connector structure design ensures that the cable joints can maintain continuous and reliable electrical connection even in vibration and dusty environments, improving the freedom of movement and operational continuity of the equipment during scanning operations.

[0052] Example 2:

[0053] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 3 The long-distance three-dimensional scanning cable assembly in this embodiment also includes a first protective sleeve 3, which is connected to the tail of the first connecting connector 12, the tail of the second connecting connector 13, the tail of the power input connector 22 and the tail of the power output connector 23.

[0054] Specifically, the ends of the four connectors are wrapped by the first protective sleeve 3, forming a continuous stress buffer layer. When the cable is subjected to axial tension, the elastic deformation of the protective sleeve absorbs the concentrated stress generated by the cable bending, reducing the stress peak to below the material's yield strength. In 3D scanning operations, frequent cable dragging causes repeated bending at the connector root; the protective sleeve, by evenly distributing the bending moment, prevents single-point stress from exceeding the fatigue limit of the copper conductor. For power output and input connectors, the annular support structure of the first protective sleeve 3 suppresses shaking during connector insertion and removal, ensuring connection stability.

[0055] The above design effectively prevents conductor breakage or insulation cracking at the connector root, and the contact resistance fluctuation range is controlled within ±5% after 5000 insertions and removals. During scanning operations, when the cable drag force reaches 80 Newtons, the protective sleeve reduces the strain at the connector root to below 0.15%, preventing plastic deformation. This structure allows the cable assembly to maintain its bending resistance in environments ranging from -20℃ to 70℃, extending its service life to 2.3-2.8 times that of conventional products.

[0056] In some embodiments, a second protective sleeve 4 is also included, which surrounds the bifurcation area of ​​the signal transmission cable 1 and the power supply cable 2. The bifurcation area refers to the transition section where the signal transmission cable 1 and the power supply cable 2 separate from their parallel state into independent paths. Specifically, the bifurcation can be achieved by partially fusing the outer sheaths of the two cables. This area is prone to stress concentration due to changes in the cable's direction of movement.

[0057] Specifically, during 3D scanning operations, when the cable assembly is dragged, the bifurcation area experiences tensile forces from different directions. The second protective sleeve 4 secures the cable around the bifurcation point through a ring-shaped wrapping method, ensuring that the stress generated when the cable bends is evenly distributed along the length of the protective sleeve. The longitudinal reinforcing ribs inside the protective sleeve guide the bending direction, preventing sharp-angle bends at the bifurcation point. Simultaneously, the wavy texture on the outer surface of the protective sleeve increases friction with the operator's hand, preventing accidental cable slippage. Through this design, the second protective sleeve 4 protects the bifurcation point of the signal transmission cable 1 and the power supply cable 2, ensuring a fixed branch length and preventing the signal transmission cable 1 and power supply cable 2 from separating indefinitely during use. It also effectively reduces the risk of conductor breakage due to bending in the bifurcation area, and minimizes signal transmission anomalies or short-circuit faults caused by insulation damage.

[0058] In some embodiments, both the first protective sleeve 3 and the second protective sleeve 4 are provided with uniformly arranged stress buffer grooves 31. The stress buffer grooves 31 refer to regular geometric recessed structures set along the surface of the protective sleeve, which can be implemented by U-shaped or V-shaped grooves distributed in a ring array. The depth and spacing of the grooves are designed to be adapted to the cable diameter.

[0059] Specifically, when the cable assembly is bent or twisted, the stress buffer groove 31 guides the external force to be transmitted in multiple directions along the edge of the groove, preventing stress concentration at a single point in the joint welding point or bifurcation area. The stress buffer groove 31 of the first protective sleeve 3 forms a progressive stiffness transition at the end of the joint, causing elastic deformation rather than plastic fracture at the connection between the cable body and the metal joint. The stress buffer groove 31 of the second protective sleeve 4 forms a mesh-like stress distribution in the bifurcation area. The mutual restraint between the grooves balances the tension difference between the two sides of the cable, preventing material tearing at the bifurcation point due to uneven stress, effectively improving the cable's service life, while maintaining signal transmission stability and power supply continuity, meeting the reliability requirements of high-intensity use in industrial environments.

[0060] In some embodiments, see Figure 4 It also includes an adhesive 5, which connects the signal transmission cable 1 and the power supply cable 2. The adhesive 5 can be injection molded using a double-hole mold.

[0061] Specifically, an adhesive 5 is applied to the parallel sections of the signal transmission cable 1 and the power supply cable 2, forming a composite cable structure. When the cable assembly is dragged, the adhesive 5 restricts the relative displacement between the two cables through evenly distributed adhesive points, preventing tangling caused by independent movement. In bifurcation areas where different devices need to be connected, the operator can separate the adhesive 5 along a pre-cut line, allowing the signal transmission cable 1 and the power supply cable 2 to extend independently to their respective connectors. This structure maintains the integrity of the cable while allowing for functional separation at specific locations. Through this design, this application solves the problem of layout chaos caused by easy separation of cable assemblies during movement and reduces dragging resistance caused by cable dispersion. In large object scanning operations, this structure allows the operator to drag the composite cable as a whole with one hand while ensuring the stability of the connector connection in the bifurcation area.

[0062] Example 3:

[0063] This embodiment is based on the above embodiment; please refer to [link / reference]. Figure 5 A three-dimensional scanning device 200 is provided, including the aforementioned long-distance three-dimensional scanning cable assembly 100.

[0064] The 3D scanning device 200 in this embodiment, by adopting the aforementioned long-distance 3D scanning cable assembly 100, eliminates the amplifier module in the middle of the data cable, thereby reducing the overall weight. This makes it convenient and easy for operators to move the cable during 3D scanning. Furthermore, the cable assembly is suitable for long-distance transmission, specifically up to 20-60 meters, meeting the data scanning needs of large and ultra-large parts or complete machine parts, ensuring smooth scanning operations, and thus improving the efficiency of scanning work.
