[0016] 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.

[0017] Please see Figure 1-3 This utility model provides a technical solution: A retractable pull strap structure for an instrument panel includes: Instrument panel 1, pull strap 3, and pull strap 3 mounting assembly for mounting pull strap 3; The pull strap 3 mounting assembly includes a rear bracket 2 and a front bracket 6. A mounting position for the pull strap 3 is reserved on the instrument panel 1. The instrument panel 1 is equipped with mounting surfaces and contoured channels that are compatible with the front bracket 6 and the rear bracket 2 to ensure that the movement trajectory of the pull strap 3 is smooth and does not interfere with other parts of the instrument panel 1. The pull strap 3 is fixed to the instrument panel 1 through the pull strap 3 mounting assembly.

[0018] Specifically, the dashboard 1 has an internal frame 7. The rear support 2 is fixed to the frame 7 with mounting screws 5 and has a limiting hole. The front support 6 has a guide contouring structure that matches the contouring channel of the dashboard 1 and is fixed to the frame 7 with mounting screws 5. The rear end of the pull strap 3 is fixed to the rear support 2 with an anti-detachment structure, and the front end of the pull strap 3 is fixed to the frame 7 after being connected to an elastic telescopic mechanism via a guide structure. The elastic telescopic mechanism is a spring 4, one end of which is fixedly connected to the front end of the pull strap 3, and the other end of which is hooked to the frame 7 via a spring 4 fixing seat. The anti-detachment structure is an injection-molded plastic block integrally formed with the pull strap 3 body. The diameter of the block is larger than the diameter of the limiting hole to prevent the pull strap 3 from completely detaching. The guide contouring structure is a parabolic guide groove with a wear-resistant coating sprayed on the surface. A shock-absorbing pad is provided between the rear support 2 and the frame 7.

[0019] The dashboard is typically made of injection molded PP (polypropylene), ABS / PC alloy, etc., and the surface may be covered with PVC or genuine leather.

[0020] The pull tab opening is located on the storage box door panel or the surface of a designated functional area. The edges of the opening must be rounded (R angle ≥ 1.5mm) and covered with a soft decorative ring (such as TPU or silicone) to prevent the pull tab from making noise or wear due to long-term friction, while also improving the tactile feel.

[0021] The contoured channel, located inside the instrument panel, utilizes reinforcing ribs and variations in wall thickness to create a smooth, three-dimensional tunnel leading from the opening to the internal frame mounting area. The cross-sectional area of ​​this channel is at least three times that of the cable tie, ensuring that the cable tie does not rigidly interfere with the channel wall at any extension or contraction angle. A low-friction coefficient coating (such as a Teflon coating) can be applied to the inner wall of the channel.

[0022] The webbing is preferably made of high-toughness, low-creep polyamide fibers (such as nylon 6) or polyester (PES) fibers. The yarn specifications must guarantee a tensile strength ≥1500N (far exceeding the 100N usage requirement, providing a high safety factor). The weaving structure employs a double or triple plain weave for reinforcement. The inner layer provides the main strength, while the outer layer has a denser weave and can incorporate anti-slip patterns (such as diamond or wavy protrusions) directly during weaving. The webbing edges are heat-sealed or laser-sealed to prevent fraying. The surface treatment is an impregnation with polyurethane (PU) or silicone coating, enhancing abrasion resistance, water and stain resistance, and providing a certain degree of surface damping.

[0023] Please refer to Figure 1-3 : The front bracket 6 is made of ABS engineering plastic in one piece and is fixed to the preset mounting surface of the frame 7 by mounting screws 5. The bracket has a pull strap 3 limiting hole in the middle and the inner wall of the hole is provided with an anti-slip rubber ring. The front bracket 6 is made of the same material in one piece and is fixed to the opening and closing end of the functional component (such as the storage box) of the instrument panel 1 by mounting screws 5. The bracket has a contour guide groove (the width of which is adapted to the pull strap 3) and the inner wall of the guide groove is smooth. The rear bracket 2 is rigidly fixed to the instrument panel 1 by mounting screws 5, and the limiting hole radially positions the rear end of the pull belt 3; the front bracket 6 is fixed to the functional component, and the contour guide groove guides the movement trajectory of the front end of the pull belt 3, ensuring that the pull belt 3 moves smoothly in the preset direction without jamming when it extends or retracts.

[0024] Please refer to Figure 1-3 : The pull strap 3 is made of nylon webbing with a tensile strength of ≥100N and has anti-slip texture on the surface to improve grip comfort. One end of the pull strap 3 passes through the limiting hole of the rear bracket 2, and the other end extends to the functional component through the contour guide groove of the front bracket 6. The anti-detachment structure is set at the rear end of the pull strap 3 and is made of injection-molded plastic block, which is integrally formed with the pull strap 3 body. The diameter of the block is larger than the diameter of the limiting hole to prevent the pull strap 3 from completely detaching.

[0025] The user pulls the main body of the pull strap 3 to open and close the driving function component. The pull strap 3 extends and retracts along the guide structure of the front and rear brackets 2. The anti-detachment structure prevents the pull strap 3 from coming out of the limiting hole of the rear bracket 2 through size limit, ensuring the safety of use.

[0026] Please refer to Figure 1-3 : Spring 4 is a cylindrical helical tension spring 4 (stiffness coefficient can be 1N / mm), one end is fixedly connected to the front end of the pull strap 3, and the other end is hung on the frame 7 through the spring 4 fixing seat; the spring 4 fixing seat can be a sheet metal stamping part, which is fixed to the frame 7 by welding, and is provided with spring 4 hanging hole.

[0027] When the functional component is closed, the spring 4 is in a naturally extended state, and the pull strap 3 is automatically retracted when pulled, with no excess length exposed; when the user pulls the pull strap 3, the spring 4 is stretched to generate reverse tension, providing uniform tension feedback; when the tension is too great, the spring 4 buffers the instantaneous impact force through elastic deformation to prevent the pull strap 3 from breaking.

[0028] Please refer to Figure 1-3 : A plush noise-reducing pad (0.8mm thick) is pasted inside the guide groove of the front bracket 6 to reduce friction noise; the anti-slip rubber rings in the limiting holes of the rear bracket 2 have both noise reduction and cushioning functions.

[0029] The plush noise-reducing pad fills the gap between the pull strap 3 and the guide groove to avoid hard contact friction; the anti-slip rubber ring absorbs vibration through elastic deformation and reduces motion noise.

[0030] When using it, the following steps are included: 1. Initial (Closed) State: The storage box is closed. The spring is in its minimum extension state (or designed pre-tension state), and its rebound force is transmitted through the pull strap, so that the front end of the pull strap is tightly against the inner end of the front bracket guide groove, and the pull strap body is completely stored inside the dashboard, with a clean outer surface.

[0031] 2. Startup process (user pull): Phase 1 (Overcoming Static Friction, Starting): The user inserts their finger into the opening of the pull strap and applies pulling force, starting the system. At this time, the user can feel a clear but not strong starting force, providing a good sense of operational confirmation.

[0032] Phase Two (Smooth Extension): As the user continues to pull, the strap overcomes the gradually increasing tension of the spring and dynamic friction, smoothly exiting the guide slot of the front bracket. The spring tension provides linearly increasing force feedback, allowing the user to perceive the length pulled out and the required force, enabling controllable and precise operation. The parabolic guide slot of the front bracket ensures a smooth strap pulling trajectory without sudden resistance.

[0033] Phase Three (Driving Functional Components): After the pull strap is pulled out to a certain length, its front end (via the front bracket) begins to apply an opening force to the storage box door panel or functional components, driving them to rotate or slide open. The spring force and the user's pulling force work together to assist the opening movement.

[0034] 3. Holding and Adjustment: At any position during the opening process, the user can stop pulling. At this point, the system is in static equilibrium. The spring force keeps the pull strap taut and prevents it from slackening. The user can steplessly adjust the extension length of the pull strap by adjusting the pulling force to suit the most comfortable grip position.

[0035] 4. Closing and Automatic Return: The user releases the pull strap or gently pushes the storage compartment to begin closing. At this point, the restoring force of the spring becomes the driving force, pulling the pull strap back smoothly and evenly into the guide groove of the front bracket. The rubber ring of the rear bracket provides appropriate damping to prevent the pull strap from retracting too quickly and producing a "clattering" sound. Finally, the pull strap fully resets, and the system returns to its initial state.

[0036] 5. Safety Protection Mechanism (Overload Scenario): In the event of an abnormal overload (such as sudden pulling or jamming), the spring acts as a mechanical safety fuse. Its maximum deformation is designed to be below the safety limits of the system's mechanical strength (such as the breaking strength of the strap and the hinge strength). When an overload occurs, the spring is stretched to near its maximum coil or maximum design stroke, absorbing the impact energy and preventing instantaneous failure caused by rigid connections. Simultaneously, the significant spring force may also help overcome some minor jamming.

[0037] In summary, it achieves stepless, adaptive adjustment of the strap working length, truly meeting the needs of the percentile group and significantly improving operational comfort; it also achieves intelligent interaction that "appears when needed and disappears when not in use," greatly enhancing the simplicity and sophistication of the interior. Linear and perceptible spring force feedback provides a clear mechanical feel and controllability during operation, while the built-in overload protection mechanism offers additional safety redundancy; through multi-level noise reduction design (rubber rings, plush pads, low-friction coating), it achieves near-silent operation, meeting the pursuit of quietness in high-end vehicles.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
