Description

Technical Field

[0001] This utility model relates to the field of buckle technology, and in particular to a strap buckle. Background Technology

[0002] Strap-type buckles are fastening devices widely used in sports equipment, medical devices, clothing, and footwear to adjust and secure the tightness of straps. Traditional strap-type buckles typically employ mechanical locking structures, such as snaps, Velcro, or gear-type adjustment mechanisms, relying on manual operation to tighten or loosen the straps. However, these structures have several problems in practical use. First, users must manually tighten and secure the straps, making it difficult to quickly adjust the tightness, especially during exercise, thus affecting the user experience. Second, mechanical buckles are prone to loosening due to external force or prolonged use, causing the straps to slip and failing to maintain a stable tightness. Furthermore, traditional buckles cannot adjust the strap pressure in real time according to user needs, such as further tightening the straps during exercise to improve support. Therefore, providing a strap-type buckle is essential. Utility Model Content

[0003] This utility model aims to solve at least one of the above-mentioned technical problems.

[0004] To solve the above problems, the first objective of this utility model is to provide a strap-type buckle, which includes: an assembly part; a locking part, the locking part cooperating with the assembly part, the locking part including a driving device and a power supply device, the driving device and the power supply device being connected.

[0005] With the cooperation of the drive unit and power supply unit, users can control the tightening or loosening of the straps with a single button, making operation more convenient and efficient. The drive unit can precisely control the tension of the straps, ensuring that the straps will not loosen accidentally during movement or use, providing a more reliable fixation effect. The drive unit and power supply unit are integrated inside the locking mechanism, optimizing space layout and making the overall structure lightweight. The power supply unit can use a rechargeable battery or a low-power design, activating the drive unit only when needed, reducing energy consumption and extending usage time. This strap-type buckle, through its electric drive and intelligent power supply design, achieves fast, stable, and automated adjustment of the straps, solving the problems of inconvenient adjustment and easy loosening of traditional mechanical buckles, making it suitable for scenarios with high requirements for convenience and functionality.

[0006] In the above technical solution, the engaging component is provided with a drive groove, and the drive device is placed in the drive groove.

[0007] The drive slot provides a fixed mounting space for the drive unit, ensuring its stability within the locking assembly and preventing displacement due to vibration or external forces, thus guaranteeing the reliability of the strap tightening / loosening process. Through a well-designed layout, the drive unit can be precisely embedded within the locking assembly, reducing additional space requirements and resulting in a thinner overall structure, suitable for applications with strict volume constraints. The drive slot provides physical isolation for the drive unit, reducing the impact of external dust, moisture, or mechanical impact, lowering the failure rate, and improving durability. As a standardized mounting position, the drive slot simplifies the production assembly process and facilitates later disassembly, maintenance, or replacement of the drive unit. The design of the drive slot forms an integrated support structure with the locking assembly housing, distributing the stress generated during drive unit operation and preventing housing deformation or cracking.

[0008] In any of the above technical solutions, the engaging component is provided with a power supply slot, and the power supply device is placed inside the power supply slot.

[0009] The power supply slot provides a fixed installation space for the power supply device, preventing it from shaking or shifting within the locking mechanism, ensuring the reliability of the power supply connection, and avoiding poor contact or power outages caused by vibration or movement. The power supply slot can be customized in layout according to the shape and size of the power supply device, allowing it to efficiently cooperate with components such as the drive slot and locking mechanism, reducing redundant space occupation and making the overall structure lighter and more compact, suitable for size-sensitive applications such as wearable devices. The power supply slot provides physical isolation for the power supply device, reducing the corrosive effects of external environments such as sweat, rain, and dust on the battery or circuitry, lowering the risk of short circuits and corrosion, and improving the product's durability in outdoor or sports environments. As a standardized installation location, the power supply slot simplifies the production and assembly process, while also supporting quick replacement of batteries or circuit modules, facilitating user maintenance or upgrades.

[0010] In any of the above technical solutions, the power supply device is equipped with a switch, which is located at the end of the engaging component away from the assembly.

[0011] The switch is located at the end of the locking assembly, furthest from the attachment, placing the operating area on the exposed part of the strap system. Users can quickly locate the switch by touch without searching, enabling one-handed blind operation. This significantly improves operational efficiency in sports scenarios. The end-positioning of the switch facilitates centralized sealing and physical isolation from the mechanical connection area with the attachment, preventing sweat / dust from seeping into the internal circuitry through the switch gaps, thus improving reliability for outdoor use. The independently located switch module at the end allows for individual removal and replacement in case of damage, eliminating the need to disassemble the entire locking assembly structure and significantly reducing maintenance costs.

[0012] In any of the above technical solutions, the assembly includes a locking groove, and the engaging component cooperates with the locking groove.

[0013] The locking groove and the engaging component form a precise fit, ensuring standardized alignment with each engagement. This prevents strap twisting or uneven stress caused by misalignment, significantly improving assembly repeatability. Before the electric drive unit operates, the locking groove physically engages, establishing initial fixation. This electromechanical separation design maintains basic fastening functionality even in the event of a sudden power outage, greatly enhancing safety compared to purely electronic locking solutions. The locking groove structure distributes strap tension across the entire assembly frame, reducing localized pressure compared to grooveless planar contact solutions and effectively preventing creep deformation of plastic parts due to long-term use.

[0014] In any of the above technical solutions, the engaging component is provided with a locking block, which cooperates with the locking groove.

[0015] The locking block, once embedded in the locking groove, forms a physical lock, preventing the locking element from accidentally detaching from the assembly and ensuring a more secure strap fixation. The mating structure of the locking block and locking groove ensures precise alignment between the locking element and the assembly, preventing misalignment or tilting and improving the overall structural stability. Users simply push the locking element into the assembly, and the locking block automatically engages in the locking groove for quick locking, reducing additional steps. The contact surface between the locking block and the locking groove distributes the strap tension, reducing localized stress concentration and extending service life. The locking block is designed to be elastically deformable or press-released, allowing users to easily press or slide to unlock, improving ease of use. The locking block can employ a hook-type structure, forming a forced physical interlock with the locking groove, resisting greater axial tensile force and significantly improving tensile strength compared to traditional friction-type locking mechanisms.

[0016] In any of the above technical solutions, the locking groove is provided with a locking hole, which cooperates with the locking block.

[0017] The locking hole provides precise positioning space for the locking block, forming a more robust mechanical interlocking structure. This effectively prevents the locking block from accidentally dislodging under stress, improving the overall tensile strength of the structure. A distinct "click" tactile feedback is produced when the locking block engages with the locking hole, allowing users to confirm that the latch is fully engaged and enabling blind operation. The locking hole provides circumferential constraint on the locking block, preventing the latch components from shaking or deflecting during use. Attached Figure Description
