Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, specifically to a tower-shaped rubber tie rod structure. Background Technology

[0002] Traditional motorcycle storage boxes typically use rigid metal or plastic latches to connect the lid and the box. This connection method, due to assembly gaps, makes the lid prone to colliding with the box during riding due to vibrations, generating noise and affecting riding comfort and experience. Rubber materials not only effectively absorb and dampen vibrations but also provide continuous preload through their tensile resilience, ensuring the lid remains firmly against the box and preventing collisions, effectively solving the noise problem.

[0003] Chinese utility model patent CN201737083U proposes a solution for securing the motorcycle storage basket lid with a strip rubber buckle. However, this structure relies solely on the elasticity of the rubber for tension and fixation, lacking a dedicated limiting design. Over time, the rubber's elasticity diminishes due to aging and temperature changes, leading to insufficient limiting capability. Furthermore, its installation structure is relatively complex, increasing the difficulty and cost of the production process. Therefore, there is an urgent need for a rubber strap structure with optimized structural design that balances anti-fall-off and easy installation performance. Summary of the Invention

[0004] The purpose of this invention is to provide a tower-shaped rubber tie bar structure to solve the problems of easy detachment and insufficient limiting ability of existing rubber tie bars due to aging after long-term use.

[0005] Another objective of this invention is to design a leverage point for the tool, making it easier for production line workers to install and position the tool, thus facilitating production.

[0006] The technical solution of this utility model is: a tower-shaped rubber pull strip structure, including an integrally formed elongated rubber pull strip body 1. The fixing part 11 of the body 1 is engaged with the snap-fit ​​22 of the rear panel 2. One end of the fixing part 11 is provided with an elastic extension part 13. The elastic extension part 13 has a through hole 15 in the middle, which abuts against the protrusion 31 of the rear storage box cover 3. The rubber pull strip body 1 and the protrusion 31 form an angle α, 0° < α < 90°. This tower-shaped rubber pull strip structure achieves fixed positioning by the integrally formed elongated body 1 and the engagement of the fixing part 11 with the snap-fit ​​22 of the rear panel 2. The through hole 15 of the elastic extension part 13 elastically stretches and recovers, tightly abutting and locking with the protrusion 31 of the rear storage box cover 3. The operating part 12 and the protrusion 31 form an acute angle of 0° < α < 90°, which can achieve mechanically assisted anti-detachment and enhance the self-locking ability of the rubber pull strip.

[0007] Preferably, the secondary tower-shaped structure 111 of the fixing part 11 is arranged in opposite directions to the main tower-shaped structure 112, with their bottoms close to each other and forming a groove 113 in the middle. The reverse arrangement allows the double towers to wrap around and lock into the rear panel latch 22 from both sides, forming a bottom support with the groove 113, enhancing the locking stability. At the same time, the reverse structure disperses the force and avoids stress concentration on one side.

[0008] Preferably, the secondary tower-shaped structure 111, the main tower-shaped structure 112, and the groove 113 together form a three-point limiting for the bayonet 22. Through the three-point constraint formed by the side pressure of the tower-shaped structures on both sides and the bottom support of the groove, the axial movement and radial displacement of the bayonet are restricted in all directions, significantly improving the vibration resistance and anti-loosening ability, and it is not easy to loosen even under severe bumps.

[0009] Preferably, both the outer sides of the secondary tower structure 111 and the main tower structure 112 are gradually tapered slopes, guiding the latch 22 of the rear panel 2 to slide into the groove 113. The slope provides a guide ramp for the latch 22 to slide in, allowing it to naturally snap into the groove without precise alignment, greatly reducing the difficulty of alignment during manual installation and improving assembly efficiency.

[0010] Preferably, the operating part 12 has a spindle-shaped cross-section with dot-matrix protrusions 121. The spindle shape conforms to the hand's grip curvature, improving operating comfort; the dot-matrix protrusions increase friction, making operation less slippery, saving effort and reducing fatigue.

[0011] Preferably, the long side of the through hole 15 is parallel to the axial direction of the rubber body 1, and the elastic deformation of the elastic extension 13 under tension is concentrated in the areas on both sides of the through hole 15. This directional guidance of the deformation direction of the elastic extension 13 ensures that the expansion and contraction of the through hole 15 are controllable, resulting in more precise engagement and disengagement with the protrusion 31, and avoiding irregular deformation from affecting the locking effect.

[0012] Preferably, the edge of the through hole 15 is provided with a rounded chamfer 151. The rounded chamfer 151 guides the protrusion 31 of the rear storage box cover 3 to slide into the through hole 15. Eliminating sharp edges and guiding the protrusion 31 to slide smoothly into the through hole reduces assembly resistance and component wear, while improving the installation error tolerance rate, and even slight misalignment can lead to smooth locking.

[0013] Preferably, the other end of the fixing part 11 is provided with an extension part 14. This provides an additional force point for installation, facilitates tool clamping or prying, solves the assembly problem when the fixing part and the bayonet are too tight, and is suitable for batch installation on production lines and after-sales maintenance.

[0014] Preferably, the extension 14 is a straight extension section, providing a leverage point for installation tools and assisting in the installation of the fixing part 11 and the latch 22 of the rear panel 2. The straight structure ensures a stable lever arm when various installation tools such as pliers and screwdrivers apply force, preventing tool slippage and protecting the rubber body from damage.

[0015] Preferably, the protrusion 31 is an integrally molded structure of the rear storage box cover 3. This eliminates seams, resulting in higher structural strength and more even force distribution when it abuts against the through hole 15, preventing locking failure due to loosening of the protrusion and extending the overall service life.

[0016] The beneficial effects of this utility model are as follows: The addition of a tower-shaped limiting structure at the rear effectively increases the contact area between the rubber tie bar and the rear panel, preventing the tie bar from falling off due to insufficient limiting caused by rubber aging or deformation.

[0017] By utilizing the tool leverage point at the tail, production line workers can easily use tools for clamping operations, improving installation efficiency and reducing installation deviations.

[0018] The rubber strip has its own elasticity, which allows it to automatically spring back after being inserted into the slot, thus achieving self-locking. When it needs to be opened, usually only a certain force needs to be applied to deform the rubber strip to release it, making opening and closing convenient and quick.

[0019] The combination of rebound self-locking and mechanical limiting ensures the service life of the rubber strip. Although the elasticity of the rubber slowly decreases with aging, the mechanical limiting clamping force does not depend on the elasticity of the rubber, so that the rubber strip can always maintain sufficient resistance to separation and will not fail due to rubber aging.

[0020] The damping effect of the rubber strip effectively absorbs and attenuates the vibrations generated during motorcycle operation, prevents the connecting parts from loosening due to vibration, buffers the impact and friction between components, effectively avoids abnormal noises caused by direct contact between metal or hard plastic parts, and the soft rubber surface also reduces the risk of scratching or abrading the surrounding paint.

[0021] By increasing the width of the rubber strip body, its tensile and flexural strength are improved, preventing the strip from breaking.

[0022] Because of its simple structure, one-piece molding, and few parts, the rubber pull strip can simplify the locking component structure, reduce the number of auxiliary parts, reduce weight, and lower manufacturing and assembly costs. Attached Figure Description

[0024] like Figure 1 and Figure 2 The schematic diagram of the tower-shaped rubber pull strip installation structure shows that a tower-shaped rubber pull strip structure includes an integrally formed elongated rubber pull strip body 1. A fixing part 11 near the tail engages with a snap-fit ​​22 on the rear panel 2, providing a stable installation reference for the rubber pull strip body 1 and preventing it from swaying or misaligning due to its flexibility during subsequent operations. The middle part of the rubber pull strip body 1 is an elastic extension part 13, with a through hole 15 featuring a rounded chamfer 151, providing good elastic deformation capability. When it is necessary to lock the rear storage compartment lid 3, force is applied to the operating part 12 on the side of the pull strip body 1 away from the fixing part 11. The elastic extension part 13 is stretched along its length under tension, simultaneously causing the through hole 15 to expand synchronously, temporarily increasing its diameter. This temporarily increases the hole diameter, allowing it to engage with the protrusion 31 of the rear storage compartment lid 3, achieving locking. At this time, an angle α is formed between the protrusion 31 and the rubber body 1, where 0° < α < 90°. The protrusion 31 is an integrally molded structure of the lid 3. The protrusion is directly injection molded for injection-molded lids and directly stamped for metal lids, without the need for additional machining holes or mounting surfaces. Only the protrusion shape needs to be designed in the lid mold. The rear panel 2 and the rear storage box lid 3 are movably connected on one side by a rubber pull strip 1, while the other side is hinged. The hinge provides a stable rotation axis, and the rubber pull strip provides elastic locking and movement restraint, ensuring that the opening and closing trajectory of the lid is stable and does not jam. It can also achieve tight locking and absorb the impact of closing by means of rubber elasticity, and can be easily operated with one hand. It is compatible with manufacturing and installation tolerances, taking into account both reliability and practicality.

[0025] Because the edge of the through hole 15 is provided with a rounded chamfer 151, the hard contact of the sharp edge is transformed into a flexible guide on the rounded surface. This chamfer provides an inlet ramp for the protrusion 31 of the storage box lid 3. When the operating part 12 is pulled to expand the through hole 15 to accommodate the protrusion 31, the protrusion 31 is aligned with the rounded chamfer 151, and the operating part 12 is released. As the tension of the elastic extension part 13 is released, the elastic restoring force of the rubber causes the through hole 15 to contract. The rounded chamfer 151 guides the protrusion 31 to slide smoothly into the through hole 15. The inner wall of the through hole 15 and the outer wall of the protrusion 31 abut tightly, realizing the locking of the storage box lid 3 and the box body. At the same time, the rounded chamfer 151 increases the contact area between the protrusion 31 and the through hole 15, and the stress is dispersed from the sharp edge to a larger area of ​​the elastic extension part. When the tie rod is subjected to tension or vibration, local fatigue damage is greatly reduced, and the service life of the rubber tie rod is greatly extended compared to the structure without chamfer, making it suitable for high-frequency switching and long-term vibration application scenarios in motorcycles.

[0026] The fixed end 11 engages with the latch 22 of the rear panel 2, providing the main body 1 of the pull bar with an anchored installation position before locking, preventing the pull bar from swaying freely due to its flexibility. This design allows for more precise alignment between the main body 1 of the pull bar and the protrusion 31, eliminating the need for repeated adjustments to the pull bar position and meeting the requirements of rapid assembly. The rounded chamfer 151 at the edge of the through hole 15 transforms the sharp edge contact into a flexible, rounded guide. Even if there is a slight misalignment between the pull bar and the protrusion 31 when force is applied, the rounded chamfer can guide the protrusion 31 to slide into the through hole, significantly reducing the difficulty of alignment by hand. Users can quickly complete the locking without tools or repeated calibration. After locking, the rubber rebound force of the elastic extension 13 locks the through hole 15 with the protrusion 31, forming a constraint at both ends in conjunction with the pre-positioning of the fixed end 11. At the same time, the flexible fit of the rubber absorbs the vibration energy during motorcycle operation, preventing loosening due to rigid collisions.

[0027] The protrusion 31 forms an angle α with the rubber body 1. The design of 0° < α < 90° can achieve mechanically assisted anti-detachment and enhance the self-locking ability of the rubber strip. According to the principle of force decomposition, after locking, the tension under the acute angle can be more efficiently converted into an effective component force along the axial direction of the strip, reducing the useless radial component force. At the same time, the elastic rebound force of the rubber strip 1 will be transmitted through the acute angle α, generating a continuous lateral pressing component force on the protrusion. When the motorcycle vibrates, this component force will further strengthen the fit between the through hole and the protrusion, achieving mechanically assisted anti-detachment and preventing the rubber strip 1 from coming off due to the vibration of the motorcycle, thus preventing the rear storage box cover 3 from being unable to be tightly sealed with the rear panel 2. In addition, the acute angle layout makes the relative position of the rubber body 1 and the protrusion 31 more visually recognizable: when the user fastens the pull bar, he / she can quickly determine which direction the operating part 12 should pull and which angle the through hole 15 should be aligned with the protrusion 31 by means of the angle relationship, which can shorten the fastening and alignment time even in low light or when wearing gloves.

[0028] like Figure 3 and Figure 4 The tower-shaped rubber strip main structure shown has a rubber strip main body 1 that is integrally formed and includes an operating part 12, an elastic extension part 13, a fixing part 11, and an extension part 14 in sequence.

[0029] The operating section 12 has a spindle-shaped cross-section, and the gripping part is equipped with a dot-matrix pattern of protrusions 121. This design incorporates ergonomics, tribology, and aesthetic considerations. Firstly, the spindle shape meets ergonomic design requirements, making it easy to grip. The curved surface of the spindle better conforms to the curvature of the fingers, especially the pads of the thumb and forefinger, making the grip more natural and comfortable, reducing localized pressure. This shape clearly indicates the optimal point of force application, allowing users to operate intuitively without searching, thus improving efficiency. Compared to a flat or cylindrical end, the spindle shape provides a larger surface area, allowing fingers to make fuller contact and exert more force, making pulling easier. The curved structure also creates a tendency to converge towards the center under force, helping to prevent fingers from slipping from the sides during pulling. At the same time, the streamlined spindle body looks more refined and high-end than a simple cube or cylinder, enhancing the overall texture and design of the product.

[0030] The core function of the dot-matrix raised 121, based on human-computer interaction design, is to significantly increase friction while guiding user operation. The dot-matrix raised 121 greatly increases the micro-friction coefficient between the finger and the pull strip contact surface. Even with sweat, oil, or water on the user's hands, the raised structure effectively pierces the liquid film, providing reliable grip and preventing slippage. The uneven surface provides a unique tactile feel to the fingers, contrasting sharply with the smooth surface of the rest of the product; this tactile signal silently tells the user that they have the correct grip. In situations where visibility is limited, such as operating in the dark, users can quickly locate and operate the rubber pull strip by touch alone, improving safety and convenience. Furthermore, the depressions between the dots act as tiny channels, allowing sweat or liquid to drain quickly instead of accumulating on the contact surface, thus keeping the surface dry and providing anti-slip properties.

[0031] The combination of the spindle-shaped structure and the dot-matrix raised 121 achieves a synergistic effect: the spindle shape solves the problem of easy gripping, while the dot-matrix raised 121 ensures a firm grip. Together, they deliver an effortless, labor-saving, and reliable ultimate user experience. This design optimizes the rubber pull strip from three dimensions: visual appeal (aesthetically pleasing shape), tactile comfort (comfortable grip and anti-slip raised ridges), and functional efficiency (labor-saving and reliable).

[0032] The elastic extension 13, serving as the central flexible functional section of the rubber strip body, employs a variable cross-section design relative to the overall structure. A variable cross-section design refers to a design method in structural engineering or mechanical design that varies the cross-sectional shape or size of a component according to different stress conditions. This design can better adapt to the stress requirements of different parts, thereby improving material utilization efficiency, reducing structural weight, and enhancing overall performance. Compared to the fixing part 11 of the tower-shaped fixed structure and the operating part 12 of the spindle-shaped structure, the thickness of the elastic extension 13 is significantly reduced, and a through hole 15 is provided in the middle, so that the main elastic deformation of the rubber when pulled is located on both sides of the through hole 15.

[0033] The tower-shaped fixing part 11 and the spindle-shaped operating part 12, due to their large thickness and high strength, are difficult to undergo elastic deformation. However, the elastic extension part 13, through its reduced thickness and central through-hole design, significantly reduces the structural stiffness of this area. When the operating part 12 is pulled, the pulling force preferentially acts on the thin-walled areas on both sides of the through-hole 15, causing the elastic deformation to be concentrated and controllably occurring within the predetermined elastic extension part, rather than being dispersed to the fixing part or the operating part. This directional deformation makes the relationship between the elastic deformation of the pull bar and the pulling force more stable and predictable. Users can precisely control the expansion and contraction of the through-hole 15 by pulling the operating part, easily achieving engagement and disengagement with the storage box lid protrusion, improving the consistency of the locking operation. Since the difficulty of elastic deformation is positively correlated with the moment of inertia of the rubber cross-section, the thicker and wider the cross-section, the greater the moment of inertia, and the greater the pulling force required for deformation. With the significant reduction in thickness of the elastic extension 13, its cross-sectional moment of inertia is greatly reduced. Only a small pulling force is needed to generate sufficient elastic stretch on both sides of the through-hole 15, allowing the through-hole to expand and fit the protrusion. This allows users to easily pull the operating part, greatly improving the convenience and effortlessness of human-machine interaction. Traditional rubber strips, if directly connecting thick and thin sections, are prone to fatigue fracture at the joint due to sudden stress changes. In this design, a tower-shaped and spindle-shaped structure provides a smooth transition between the thick and thin sections, resulting in a more uniform and dispersed stress distribution.

[0034] The fixing part 11 serves as the main connection structure between the rubber strip 1 and the rear panel 2. It is formed by the sub-tower structure 111, the main tower structure 112, and the groove 113. The sub-tower structure 111 is arranged opposite to the main tower structure 112, and the main tower structure 112 is enlarged to be larger than the sub-tower structure 111.

[0035] The secondary tower structure 111 and the main tower structure 112 wrap around the latch 22 from both sides, forming a "clamping" engagement. The groove 113 supports the bottom of the latch, and the three work together to create a three-point limiting mechanism that can resist the pull force along the axial direction of the pull bar. The symmetrical layout of the double towers makes the force distribution more even when the latch is under tension, avoiding the problem of uneven force on one side when using a single tower engagement. Even if the pull bar is subjected to torsional force, such as in the event of an accidental collision with the storage box lid, the double towers can offset the torque through the reverse restraint on both sides, reducing the risk of torsional loosening.

[0036] The outer side of the tower-shaped structure is designed with a gradually sloping surface. When the rear panel latch is aligned with the fixing part, precise alignment is not required; it can naturally slide into the groove 113 along the sloping surface. If the rear panel latch has a slight positional deviation due to processing errors, the slight deformation of the rubber material of the double-tower structure can accommodate the deviation, avoiding the assembly difficulties caused by tolerances in traditional rigid snap-fit ​​connections. After snap-fitting, the inner stepped structure of the tower-shaped structure will embed into the edge of the rear panel latch, forming a mechanical stop. The depth design of the groove 113 further restricts the axial movement of the latch, and even if the rubber ages, it can still prevent detachment through structural limiting. If the main tower-shaped structure 112 undergoes slight deformation under stress, the secondary tower-shaped structure 111 can fill the gap and provide support, forming a double redundancy of main tower load-bearing and secondary tower anti-loosening, completely eliminating the risk of single-point failure.

[0037] The design of the main tower structure 112 being larger than the secondary tower structure 111 represents a precise optimization of stress layering, assembly efficiency, and structural redundancy. When the rubber strip is under tension, the force is transmitted to the fixing part 11 through the elastic extension 13. The main tower structure 112 directly bears most of the tension. Increasing the cross-sectional dimensions of the main tower, such as its width and thickness, can improve its tensile strength and fatigue life, preventing breakage after long-term stress. The secondary tower structure 111 is slightly smaller in size, which can accommodate minor positional deviations in the rear panel latches and reduce the amount of rubber used while ensuring the anti-detachment function. It also avoids structural redundancy and weight increase caused by identical dimensions of the two towers. The relatively arranged dual tower structures, through the combination of elastic deformation of the rubber and mechanical limiting of the structure, solve the problem of easy loosening of rigid latches and avoid the lack of durability of purely elastic latches. The size difference between the main and secondary towers is a precise implementation of functional layering and cost optimization, ultimately achieving the design goal of long-term product reliability.

[0038] The extension section 14, as the extended force-applying section of the rubber strip's tail, has a straight structure and clearly defined boundaries, providing a leverage point for precise installation tools. It amplifies operating force through the lever principle: when using a tool to clamp the extension section 14, its length acts as a lever arm, converting the small force applied by the hand into a large clamping force on the latch 22. Especially in scenarios where the latch is too tight and the rubber strip needs to be forcibly inserted, the clamping can be easily completed without additional hand strength. For assembly workers, the force-saving effect of the extension section reduces hand fatigue caused by repetitive operations, improving efficiency and experience during batch assembly.

[0039] The extension section 14 bears the main load during installation, indirectly protecting the core functional area of ​​the rubber tie rod. Direct force applied to the rubber body can easily lead to wear on the inclined surface of the tower structure and premature fatigue of the elastic extension section 13. However, the extension section 14, through force transfer, concentrates the assembly stress at the tail end, ensuring that the critical functional area of ​​the rubber body is almost undamaged, thus extending the overall lifespan of the rubber tie rod. Simultaneously, the extension characteristic of the extension section 14 makes the tail end of the tie rod easier to observe and operate during assembly. In the narrow slot space of the motorcycle rear panel, the extension section 14 can extend beyond the obstructed area, allowing workers to visually confirm the alignment of the tie rod with the latch 22, guiding them to quickly determine if the tie rod is properly engaged and improving assembly alignment efficiency. When the tie rod needs replacement due to aging, maintenance personnel can use tools to clamp the extension section 14 and quickly pull the old tie rod out of the latch 22 without forcibly tearing the rubber body, thus avoiding damage to the latch structure of the storage box.

[0040] The assembly process of this utility model structure is as follows: First, insert the tower-shaped rubber strip 1 into the slot 21 of the rear panel 2, so that the extension 14 at the tail end of the tower-shaped rubber strip 1 passes through the buckle 22. At this time, the rubber strip is initially in the slot, but it is not yet fully locked and positioned.

[0041] Then, using the prepared tool, clamp the extension 14 and use the extension 14 as a leverage point to smoothly pull the rubber strip 1. Due to the gradually changing slope design of the main tower-shaped structure 112, which is larger at the top and smaller at the bottom, it provides self-guiding capability for the active engagement of the tower-shaped rubber strip 1. The slope of the tower shape will actively capture the buckle 22. Even if there is a slight deviation in the movement trajectory of the strip 1, the buckle 22 can naturally slide into the groove 113 along the slope of the tower shape without strict alignment. At the same time, the rubber material of the strip causes the main tower-shaped structure 112 to undergo elastic deformation when passing through the buckle 22, making it easier to pass through the buckle 22 and making the groove 113 on the rubber strip 1 precisely engage with the buckle 22.

[0042] Because the secondary tower-shaped structure 111 and the primary tower-shaped structure 112 are arranged in opposite directions, the bottoms of the primary tower-shaped structure 112 and the secondary tower-shaped structure 111, respectively located at both ends of the groove 113, simultaneously limit the buckle 22, abutting against it to achieve bidirectional locking. At the same time, the three surfaces of the primary tower-shaped structure 112, the secondary tower-shaped structure 111, and the groove 113 together wrap around the buckle 22, increasing the contact area between the tower-shaped rubber strip 1 and the buckle 22, significantly improving the axial and radial limiting capabilities, and achieving reliable fixation.

[0043] Finally, pull the operating part 12 of the rubber pull strip 1 and pull it away from the protrusion 31 of the rear storage compartment cover 3. The spindle-shaped curved surface and dot-matrix protrusions of the operating part 12 of the rubber pull strip 1 can better fit the curvature of the fingers, making operation easier and gripping more secure. The elastic extension 13 in the middle of the pull strip 1 is stretched evenly under the action of the pulling force. At the same time, the through hole 15 in the middle expands synchronously with the stretching of the elastic extension, and the inner diameter increases. After the through hole 15 is stretched to a size that can fit into the protrusion 31, align the expanded through hole 15 with the protrusion 31 of the rear storage compartment cover 3 and fit it in. Subsequently, due to the elastic recovery characteristics of rubber, the elastic extension 13 in the middle attempts to return to its original length after the pulling force is released, so that the inner wall of the through hole tightly abuts against the outer wall of the protrusion. The rounded chamfer of the inner wall of the through hole increases the contact area with the protrusion 31, and finally achieves a stable connection between the rubber pull strip and the protrusion of the compartment cover. When it is necessary to open the rear storage box cover 3, simply pull the operating part 12 and pull the rubber strip 1 away from the protrusion 31 of the rear storage box cover 3. Since the protrusion 31 and the rounded chamfer 151 are both curved surfaces, they will not get stuck and can be easily pulled out.
