Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle accessories, and particularly to a quick-release device for a motorcycle fuel tank bag. Background Art

[0002] Existing quick-release devices for motorcycle fuel tank bags (such as Chinese patents with publication numbers CN220009989U, CN221541817U, CN110139795B and European patent with publication number EP3819198A1) mainly achieve the disassembly, assembly and position adjustment of the fuel tank bag through the cooperation of a lock component and a buckle hole. However, they have significant defects in terms of lock synchronization, drive structure and sliding adjustment: 1. Insufficient lock synchronization: - Existing solutions rely on the independent drive of symmetric buckles (such as Chinese patents with publication numbers CN220009989U, CN110139795B, which use a pull rod cooperating with a triangular buckle hole, and CN221541817U which uses a pull rod cooperating with an inclined drive groove), lacking a forced synchronization mechanism. The active buckle and the driven buckle are prone to asynchronous movement due to processing errors or wear, resulting in incomplete retraction or extension of the unilateral buckle head, causing unlocking failure or insecure locking; - Poor reset stability. The reset of the buckle depends on the spring force, but the non-linear transmission path (such as the triangular buckle hole) easily causes uneven stress on the spring, resulting in the buckle shaking or incomplete rebound, affecting the precise meshing of the buckle head and the buckle hole.

[0003] 2. Inefficient drive structure: - The operating components are mostly pull tapes (such as Chinese patents with publication numbers CN220009989U, CN221541817U) or rigid push elements (such as Chinese patent with publication number CN110139795B) to drive a top column to slide in the buckle hole. Users need to apply a large pulling force to overcome multi-directional frictional forces, making the operation laborious and the feel jerky; - The combination of a flexible pull tape and a rigid transmission exacerbates the jerky feel of the operation. The pull tape is prone to wear and breakage, reducing the reliability of the device.

[0004] 3. Defects in the sliding adjustment structure: For the Chinese patent solutions with publication numbers CN220009989U, CN221541817U and the European patent solution with publication number EP3819198A1, there are the following problems; - Existing sliding adjustment relies on the frictional fixation of elastic components and mating grooves. Uneven sliding resistance results in jerks during the adjustment process, making it difficult to achieve smooth stepless adjustment; - There are gaps between the lock and the buckle hole due to machining tolerances or wear, resulting in easy loosening of the fuel tank bag after fixation, especially prone to dislocation under bumpy road conditions; - Lack of a feedback mechanism, users cannot perceive the sliding position, and need to try repeatedly to lock the target position, resulting in cumbersome operations.

[0005] The above problems seriously restrict the operation efficiency and user experience of the quick-release device, and there is an urgent need for an improved solution with strong synchronization, labor-saving operation, and smooth sliding. Summary of the Invention

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0034] As Figures 1 - 16 shown, this embodiment relates to a quick-release device for a motorcycle fuel tank bag, including a quick-release main body unit 1, a bottom plate 2 for connecting and installing the fuel tank bag, and a fuel tank cap mounting unit 3 for fixedly connecting to the edge of the motorcycle fuel tank opening.

[0035] As Figure 4 shown, the fuel tank cap mounting unit 3 can include two parts, a transfer plate 3.1 and an adapter 3.2. Both the transfer plate 3.1 and the adapter 3.2 are constructed as a matching horseshoe shape. The transfer plate 3.1 is directly fixed to the fuel tank cap of the motorcycle, and the adapter 3.2 is fixed to the transfer plate 3.1 by bolts. A buckle hole is provided on the adapter 3.2 for locking or unlocking the quick-release main body unit 1, which will be specifically described below. And magnets can be provided in both the adapter 3.2 and the quick-release main body unit 1, so that when the quick-release main body unit 1 is installed on the adapter 3.2, preliminary positioning can be achieved through the magnetic attraction structure. As Figure 3 shown in another solution, the transfer plate 3.1 and the adapter 3.2 are combined into an integrated adapter, which also has the above functions.

[0036] As Figures 5 - 9As shown in the figure, this embodiment proposes a quick-release main body unit 1, which includes a housing 4 and a locking component disposed inside the housing 4. A plurality of through holes 4.5 are provided on the side wall of the housing 4. The locking component includes a driving catch plate 5 and a driven catch plate 6 slidably disposed in the housing 4, an operating member 9 for driving the driving catch plate 5 and the driven catch plate 6 to move, and a first return spring 8. The outer ends of the driving catch plate 5 and the driven catch plate 6 are provided with catch heads 5.3, and the catch heads 5.3 can protrude or retract from the through holes 4.5. The operating member 9 is drivingly connected to the driving catch plate 5. A synchronous gear 7 is rotatably disposed in the housing 4. Rack teeth 5.4 are respectively provided at the inner ends of the driving catch plate 5 and the driven catch plate 6, and the rack teeth 5.4 are engaged with the synchronous gear 7, so that when the operating member 9 drives the driving catch plate 5 to move, the synchronous gear 7 drives the driven catch plate 6 to move synchronously. Among them, the rotational setting of the synchronous gear 7 can be realized through a bearing or a bushing to ensure the smooth rotation of the gear. The rack teeth 5.4 at the inner ends of the driving catch plate 5 and the driven catch plate 6 can be processed by milling or stamping processes, and the tooth profile of the rack teeth 5.4 can be a straight tooth or an inclined tooth, which is specifically matched according to the tooth profile of the synchronous gear 7. The operating member 9 can be in the form of a pull rod, a button or a knob, etc., and the specific design can be adjusted according to the actual application scenario. The first return spring 8 can be in the form of a helical spring, a leaf spring or a torsion spring, etc., and the elastic force of the spring should be designed according to the force required for the protrusion and retraction of the catch head 5.3. Specifically, when the operating member 9 is pulled or pressed, the driving catch plate 5 slides along the housing 4 under the drive of the operating member 9, and the rack teeth 5.4 on the driving catch plate 5 drive the synchronous gear 7 to rotate. The rotation of the synchronous gear 7 further drives the rack teeth 5.4 on the driven catch plate 6, so that the driven catch plate 6 slides synchronously. Thus, the catch heads 5.3 of the driving catch plate 5 and the driven catch plate 6 protrude or retract from the through holes 4.5 to realize the locking or unlocking function. After the operating member 9 is released, the first return spring 8 pushes the driving catch plate 5 and the driven catch plate 6 to reset, so that the catch head 5.3 returns to the initial position.

[0037] Compared with the prior art, the present application ensures the synchronous movement of the driving catch plate 5 and the driven catch plate 6 by introducing the design of the engagement between the synchronous gear 7 and the rack teeth 5.4, and solves the problem of asynchronous movement of the catch plates in the traditional design. At the same time, the direct driving connection between the operating member 9 and the driving catch plate 5 improves the operating efficiency and reduces the operating force of the user. The setting of the first return spring 8 ensures that the catch head 5.3 can automatically reset after operation, improving the convenience of use. The overall structure is simple, the operation is smooth, and it has high reliability and durability.

[0038] In a further solution, the racks 5.4 at the inner ends of the active clamping plate 5 and the racks 5.4 at the inner ends of the driven clamping plate 6 are respectively engaged on both sides of the synchronous gear 7, and the moving directions of the active clamping plate 5 and the driven clamping plate 6 are opposite. Specifically, the inner ends of the active clamping plate 5 and the driven clamping plate 6 are respectively provided with racks 5.4, and these racks 5.4 are engaged with the synchronous gear 7. Through the rotation of the synchronous gear 7, the active clamping plate 5 and the driven clamping plate 6 can achieve synchronous movement. Since the racks 5.4 are respectively located on both sides of the synchronous gear 7, the moving directions of the active clamping plate 5 and the driven clamping plate 6 are opposite, thus ensuring the synchronism and stability of the two during the movement. This design effectively solves the problem of insufficient synchronism of the active clamping plate 5 and the driven clamping plate 6 during the movement, and improves the reliability and operation efficiency of the locking component. In this regard, the technical solution of the present application makes the moving directions of the active clamping plate 5 and the driven clamping plate 6 opposite through the introduction of the synchronous gear 7, thereby realizing the synchronous movement of the two. Compared with the prior art, the technical solution of the present application significantly improves the synchronism and stability of the movement of the clamping plate, and reduces the problems of unlocking failure or insecure locking caused by non-synchronism. In addition, the design of the synchronous gear 7 simplifies the structure of the locking component, reduces the difficulty of processing and assembly, and improves the reliability and service life of the product.

[0039] Further, a guide post 10 or a guide slot 10.1 is provided in the housing 4. The active clamping plate 5 and the driven clamping plate 6 are provided with guide slots 10.1 or guide posts adapted to the guide post 10 or the guide slot 10.1. The guide post 10 is embedded in the guide slot 10.1 to limit the sliding directions of the active clamping plate 5 and the driven clamping plate 6. Specifically, the guide post 10 can be set as a cylindrical or rectangular post, and its diameter or width matches the size of the guide slot 10.1 to ensure that the guide post 10 can be smoothly embedded in the guide slot 10.1. In this regard, this technical solution ensures the stable direction of the active clamping plate 5 and the driven clamping plate 6 during the sliding process through the mutual cooperation of the guide post 10 or the guide slot 10.1 provided in the housing 4 and the guide slots 10.1 or guide posts on the active clamping plate 5 and the driven clamping plate 6, and avoids the deviation of the sliding trajectory. Thus, the sliding directions of the active clamping plate 5 and the driven clamping plate 6 are strictly limited within the paths of the guide post 10 and the guide slot 10.1, thereby improving the accuracy and reliability of the protrusion or retraction of the buckle 5.3. Compared with the prior art, this solution effectively solves the problem of unstable direction of the active clamping plate 5 and the driven clamping plate 6 during the sliding process, reduces the situations of unlocking failure or insecure locking caused by the deviation of the sliding trajectory, and improves the overall performance and user experience of the quick-release device.

[0040] Such as Figure 5 and 6As shown in FIGS. 9 and 10, the lower end surface of the housing 4 is recessed inward to form a U-shaped groove 4.3, and a U-shaped boss 4.4 is formed inside the housing 4. A through hole 4.5 is provided on the side wall of the U-shaped boss 4.4 and communicates with the U-shaped groove 4.3. The synchronous gear 7 is rotatably arranged at the center of the enclosed area of the U-shaped boss 4.4. At least a part of the inner ends of the active catch plate 5 and the driven catch plate 6 is located within the enclosed area of the U-shaped boss 4.4, and the rack 5.4 and the catch head 5.3 correspond to the synchronous gear 7 and the through hole 4.5 respectively. Specifically, the design of the U-shaped groove 4.3 enables the lower end surface of the housing 4 to be adaptively installed with the horseshoe-shaped adapter 3.2, and the formation of the U-shaped boss 4.4 further optimizes the internal space layout. The synchronous gear 7 is arranged at the center of the U-shaped boss 4.4, ensuring the synchronism of the active catch plate 5 and the driven catch plate 6 during movement. The communication design of the through hole 4.5 and the U-shaped groove 4.3 makes the extension and retraction of the catch head 5.3 smoother, improving the convenience and stability of operation. As a preferred embodiment, the depth and width of the U-shaped groove 4.3 can be adjusted according to actual needs to adapt to adapters 3.2 of different sizes. In addition, the height and shape of the U-shaped boss 4.4 can also be optimized according to the size and installation requirements of the synchronous gear 7 to ensure the meshing accuracy between the gear and the rack 5.4. In this regard, the technical solution of the present application simplifies the internal structure of the housing 4 through the design of the U-shaped groove 4.3 and the U-shaped boss 4.4, making the layout of the synchronous gear 7, the active catch plate 5 and the driven catch plate 6 more compact and reasonable. The synchronous gear 7 is arranged at the center of the U-shaped boss 4.4, ensuring the synchronism of the active catch plate 5 and the driven catch plate 6 during movement and avoiding the problem of insufficient synchronism caused by complex structure. The communication design of the through hole 4.5 and the U-shaped groove 4.3 makes the extension and retraction of the catch head 5.3 smoother, improving the convenience and stability of operation. Compared with the prior art, the technical solution of the present application not only simplifies the structure, but also improves the fluency and reliability of operation, solving the technical problems of complex structure and insufficient synchronism in the prior art.

[0041] As Figure 7 shown 8As shown, the inner end of the driven catch plate 6 is of a U-shaped structure, and the rack 5.4 is arranged on one arm of the U-shaped structure. The synchronous gear 7 is rotatably arranged within the U-shaped opening of the driven catch plate 6. The inner end of the driving catch plate 5 is a strip-shaped plate, and the rack 5.4 is arranged on the strip-shaped plate. The strip-shaped plate is inserted into the U-shaped opening of the driven catch plate 6, so that the racks 5.4 of the driving catch plate 5 and the driven catch plate 6 are respectively engaged on both sides of the synchronous gear 7. The other U-shaped arm of the driven catch plate 6 limits the strip-shaped plate of the driving catch plate 5 in the meshing direction. Specifically, the U-shaped structure design of the driven catch plate 6 enables its inner end to accommodate the synchronous gear 7 and meshes with the synchronous gear 7 through the rack 5.4, ensuring that the driven catch plate 6 and the driving catch plate 5 move synchronously under the drive of the synchronous gear 7. The strip-shaped plate of the driving catch plate 5 is inserted into the U-shaped opening of the driven catch plate 6, so that the racks 5.4 of the two are respectively located on both sides of the synchronous gear 7, ensuring the stability of meshing. The other U-shaped arm of the driven catch plate 6 limits the strip-shaped plate of the driving catch plate 5, that is, the strip-shaped plate of the driving catch plate 5 and the U-shaped structure at the inner end of the driven catch plate 6 form a biting structure, preventing the strip-shaped plate from shifting during movement and disengaging from the synchronous gear 7, ensuring that the movement directions of the two are consistent and stable. Thus, the technical solution of this application realizes the precise meshing and limitation of the driving catch plate 5 and the driven catch plate 6 under the drive of the synchronous gear 7 through the U-shaped structure design of the driven catch plate 6. Compared with the prior art, this solution not only simplifies the structure, reduces the processing and assembly difficulty, but also significantly improves the synchronism and stability of the movement of the catch plate, avoiding problems such as tooth disengagement or deviation caused by wear or processing errors, thereby enhancing the reliability and service life of the overall device.

[0042] In a specific solution, the operating component 9 drives the active buckle plate 5 and the driven buckle plate 6 to move towards each other, causing the buckle head 5.3 to retract into the housing 4. The elastic force of the first return spring 8 drives the active buckle plate 5 and the driven buckle plate 6 to move away from each other, causing the buckle head 5.3 to extend out of the housing 4. Specifically, the operating component 9 can drive the active buckle plate 5 and the driven buckle plate 6 to move towards each other in various ways. For example, the operating component 9 can be a lever structure. By manually operating the lever, the active buckle plate 5 and the driven buckle plate 6 can be moved inwards, thereby achieving the retraction of the buckle head 5.3. The first return spring 8 can be arranged between the active buckle plate 5 and the driven buckle plate 6. When the operating component 9 is released, the elastic force of the first return spring 8 will push the active buckle plate 5 and the driven buckle plate 6 outwards, causing the buckle head 5.3 to extend out of the housing 4. In addition, the first return spring 8 can also be arranged inside the housing 4, and the elastic force of the spring directly acts on the active buckle plate 5 and the driven buckle plate 6 to achieve the extension of the buckle head 5.3. Thus, through the cooperation of the operating component 9 and the first return spring 8, this technical solution realizes the stable retraction and extension of the buckle head 5.3. The operating component 9 drives the active buckle plate 5 and the driven buckle plate 6 to move towards each other, enabling the buckle head 5.3 to retract into the housing 4 and realizing the unlocking function. The first return spring 8 drives the active buckle plate 5 and the driven buckle plate 6 to move away from each other through the elastic force, enabling the buckle head 5.3 to extend out of the housing 4 and realizing the locking function. This design ensures that the buckle head 5.3 can stably retract and extend under the action of the operating component 9 and the first return spring 8, solving the technical problem of unstable movement of the buckle head 5.3. Compared with the prior art, this technical solution has the advantages of simple operation, stable structure, and long service life. The cooperation of the operating component 9 and the first return spring 8 makes the movement of the buckle head 5.3 smoother, reduces the required operating force, and improves the user experience. At the same time, this design reduces the wear of components, extends the service life of the device, and is suitable for frequently used scenarios.

[0043] In a further solution, one or more first return springs 8 are provided inside the housing 4, and the first return springs 8 abut against the active buckle plate 5 and / or the driven buckle plate 6. Specifically, by providing one or more first return springs 8, it can be ensured that the active buckle plate 5 and the driven buckle plate 6 are evenly stressed during the reset process, avoiding the problem of unstable buckle plate reset caused by uneven distribution or single setting of the first return springs 8. The distribution of the multiple first return springs 8 can enhance the reset force of the buckle plate, improve the stability of the protrusion or retraction of the buckle head 5.3, and thus enhance the reliability and user experience of the quick-release main unit 1. Among them, the first return spring 8 can be set as a helical spring, a leaf spring or other elastic elements, and the specific quantity and position can be adjusted according to actual needs. As a preferred implementation manner, only one first return spring 8 is provided inside the housing 4, and the first return spring 8 abuts against the active buckle plate 5 to reduce the reverse acting force during the driving process of the synchronous gear 7 and the rack 5.4, thereby reducing the wear of the synchronous gear 7 and the rack 5.4. When the first return spring 8 is provided on the driven buckle plate 6, the operating member 9 first acts on the active buckle plate 5, and the active buckle plate 5 needs to overcome the reset elastic force on the driven buckle plate 6 first when it wants to move, and this reset elastic force is transmitted through the cooperation of the synchronous gear 7 and the rack 5.4, so the synchronous gear 7 and the rack 5.4 will be worn. This solution can effectively reduce this kind of wear and extend the service life of the quick-release main unit 1 by optimizing the setting of the first return spring 8. Thus, the technical solution of the present application solves the technical problem of unstable buckle plate reset caused by single or uneven distribution of the first return spring 8 by reasonably setting the first return spring 8, improves the stability and reliability of the quick-release main unit 1, reduces the wear of the synchronous gear 7 and the rack 5.4 at the same time, and improves the overall quality of the product.

[0044] Such as Figure 7 and 8As shown, a locking component is provided on the housing 4, and the locking component includes a mechanical lock 11.1. The locking tongue plate 11.2 of the mechanical lock 11.1 can enter the moving path of the active catch plate 5 or the driven catch plate 6. When the locking tongue plate 11.2 enters the moving path, the locking tongue plate 11.2 abuts against the active catch plate 5 or the driven catch plate 6 to restrict its movement. When the locking tongue plate 11.2 exits the moving path, the active catch plate 5 and the driven catch plate 6 can move freely. Specifically, the entry or exit of the locking tongue plate 11.2 from the moving path can be achieved by the rotation or sliding of the mechanical lock 11.1. As a preferred embodiment, the mechanical lock 11.1 can be designed as a structure with a rotating handle, and the rotating handle drives the locking tongue plate 11.2 to enter or exit the moving path; or the locking tongue plate 11.2 is rotated by the rotation of the lock core after being unlocked by a key. In addition, the shape of the locking tongue plate 11.2 can be designed as a wedge shape or a rectangular shape, so as to more effectively abut against the catch plate when entering the moving path, thereby enhancing the stability of the locking. Further, protrusions or grooves can be provided at the end of the locking tongue plate 11.2 to cooperate with the corresponding structures on the catch plate, further improving the reliability of the locking.

[0045] In this regard, the technical solution of the present application realizes the effective restriction of the movement of the active catch plate 5 and the driven catch plate 6 in the locked state through the design of the locking component. When the locking tongue plate 11.2 enters the moving path, the locking tongue plate 11.2 is in direct contact with the catch plate, preventing its movement and ensuring the stability of the locked state. When the locking tongue plate 11.2 exits the moving path, the catch plate can move freely, realizing the unlocking function. This design solves the problem that the movement of the catch plate is not restricted in the locked state in the prior art through a simple mechanical structure, and at the same time improves the convenience of operation and the reliability of the locking. Compared with the prior art, the technical solution of the present application has the advantages of simple structure, convenient operation, stable locking, etc., and adds the functions of anti-theft and anti-forced disassembly, which can effectively improve the user experience.

[0046] Further, an extension plate 8.3 is provided on the active buckle plate 5. The locking tongue plate 11.2 can be turned into or out of the moving path of the extension plate 8.3. When the locking tongue plate 11.2 turns into the path, the locking tongue plate 11.2 abuts against the end of the extension plate 8.3 or snaps into a bayonet on the extension plate 8.3. A support plate 11.3 is also provided in the housing 4. When the locking tongue plate 11.2 turns into the path, the support plate 11.3 abuts against the other side of the locking tongue plate 11.2 to enhance the locking stability. Specifically, the extension plate 8.3 can be designed as a plate-like structure extending outward from one side of the active buckle plate 5, and a bayonet or a protrusion can be provided at its end so that the locking tongue plate 11.2 can abut or engage more firmly when turning into the path. The length and shape of the extension plate 8.3 can be adjusted according to actual needs to ensure that the locking tongue plate 11.2 can accurately align with the bayonet or the end when turning into the path. The support plate 11.3 can be fixed on the inner wall of the housing 4, and its position and shape should match the other side of the locking tongue plate 11.2 so that it can effectively abut against the locking tongue plate 11.2 when the locking tongue plate 11.2 turns into the path and prevent it from loosening or shifting. The support plate 11.3 can be made of an elastic material to provide a certain buffering effect and further enhance the locking stability. Thus, through the cooperation of the extension plate 8.3 and the support plate 11.3, the locking stability between the locking tongue plate 11.2 and the active buckle plate 5 is significantly improved. The extension plate 8.3 provides an additional contact or engagement position for the locking tongue plate 11.2, enabling the locking tongue plate 11.2 to abut or latch onto the extension plate 8.3 more firmly when turning into the path, thereby enhancing the locking stability. The support plate 11.3 abuts against the other side of the locking tongue plate 11.2 when the locking tongue plate 11.2 turns into the path, further enhancing the fixing effect of the locking tongue plate 11.2 and preventing it from loosening or shifting in the locked state. Compared with the prior art, the technical solution of the present application effectively solves the problem of insufficient locking stability between the locking tongue plate 11.2 and the active buckle plate 5 through simple structural improvements, and improves the reliability and durability of the locking component.

[0047] Such as Figure 11As shown, the operating component 9 includes a rotating shaft 9.1 rotatably arranged on the housing 4, a dial plate 9.2 located outside the housing 4, and an inner pivot arm 9.3 located inside the housing 4. The dial plate 9.2 is fixedly connected or integrally formed with the inner pivot arm 9.3. When an external force acts on the dial plate 9.2, the operating component 9 rotates around the rotating shaft 9.1, and directly or indirectly drives the active buckle 5 and the driven buckle 6 to slide through the inner pivot arm 9.3. Among them, the rotating shaft 9.1 of the operating component 9 can be fixed on the housing 4 through a bearing or a bushing to ensure the smoothness of its rotation. The connection mode between the dial plate 9.2 and the inner pivot arm 9.3 can adopt welding, bolt fixation or integral molding to enhance the structural stability. The end of the inner pivot arm 9.3 can be designed as an inclined surface or an arc surface to better contact the outer end of the active buckle 5, so as to more effectively drive the sliding of the buckle. Through the setting of the rotating operating component 9 and the linkage between the dial plate 9.2 and the inner pivot arm 9.3, this technical solution enables the user to drive the active buckle 5 and the driven buckle 6 to slide by rotating the dial plate 9.2, so as to realize the extension or retraction of the buckle head 5.3. This design avoids the multi-directional frictional force of the traditional belt pulling operation mode, simplifies the operation process, and improves the convenience and feel of the operation. The structural design of the housing 4 and the buckle assembly ensures the stability and reliability of the device, and the setting of the first return spring 8 ensures the automatic return of the buckle head 5.3 when there is no external force. The overall solution effectively solves the problems of laborious operation and astringent feel in the prior art, and improves the user experience.

[0048] The end slope of the inner pivot arm 9.3 presses against the outer end of the active buckle plate 5. The slope pressing here refers to a slope mating method that can change the direction of force. In this solution, specifically, the outer end of the active buckle plate 5 can be constructed as a slope or an arc surface for reference in the following description to achieve the slope pressing solution. When the operating member 9 rotates, the active buckle plate 5 is driven to move along the inner wall of the housing 4 through the sliding contact of the inner pivot arm 9.3, thereby converting the rotational force of the inner pivot arm 9.3 into the movement of the active buckle plate 5. During use, the operating member 9 drives the active buckle plate 5 and the driven buckle plate 6 to move towards each other, causing the buckle head 5.3 to retract into the housing 4, thereby achieving the unlocking function. The elastic force of the first return spring 8 drives the active buckle plate 5 and the driven buckle plate 6 to move away from each other, causing the buckle head 5.3 to extend out of the housing 4 to achieve the locking function. This design realizes the automatic expansion and contraction of the buckle head 5.3 through the cooperation of the operating member 9 and the first return spring 8, simplifies the operation steps, and improves the convenience of use. Compared with the prior art, the operating member 9 of this application adopts a rigid transmission structure, avoiding the problems of laborious operation and jerky feel caused by the flexible pull belt, and significantly improving the smoothness and comfort of the operation. In this regard, the technical solution of this application achieves a smoother driving effect by optimizing the contact method between the inner pivot arm 9.3 and the active buckle plate 5. Specifically, the sliding contact between the inner pivot arm 9.3 and the outer end of the active buckle plate 5 reduces the multi-directional friction in the traditional pull belt driving method, making the driving process more labor-saving and the operation smoother. Compared with the prior art, this application avoids the problems of jerky feel and laborious operation in the pull belt driving method, ensuring that the force transmission is more direct and efficient.

[0049] Furthermore, the length of the dial plate 9.2 is greater than that of the inner pivot arm 9.3, forming a labor-saving lever structure. Specifically, the dial plate 9.2 is fixedly connected or integrally formed with the inner pivot arm 9.3. When an external force acts on the dial plate 9.2, the operating member 9 rotates around the rotating shaft 9.1, and directly or indirectly drives the active buckle 5 and the driven buckle 6 to slide through the inner pivot arm 9.3. Among them, the length of the dial plate 9.2 is greater than that of the inner pivot arm 9.3, so that when the user operates the dial plate 9.2, a relatively small force can be used to drive the inner pivot arm 9.3, thereby indirectly driving the active buckle 5 and the driven buckle 6 to slide. As a preferred embodiment, the dial plate 9.2 can be designed as a long strip, and its length can be adjusted according to actual needs to ensure the maximization of the labor-saving effect. The length of the inner pivot arm 9.3 is relatively short to enhance the labor-saving effect of the lever. In addition, the connection method between the dial plate 9.2 and the inner pivot arm 9.3 can adopt various methods such as welding, bolt fixing or integral molding to ensure the stability and durability of the structure. Thus, through the design of this labor-saving lever structure, when the user operates the dial plate 9.2, a relatively small force can be used to drive the inner pivot arm 9.3, thereby indirectly driving the active buckle 5 and the driven buckle 6 to slide. This design effectively reduces the force required for the user to operate, improves the operation feel, and solves the problems of laborious operation and astringent feel in the prior art. Compared with the prior art, the technical solution of this application not only simplifies the operation process, but also significantly improves the user experience. Especially during frequent operations, it can effectively reduce hand fatigue.

[0050] As Figure 9 shown, the outer end of the active buckle 5 is constructed as an inclined surface or an arc surface, and the end of the inner pivot arm 9.3 is an arc plate; the end of the arc plate presses against the inclined surface or the arc surface of the active buckle 5. The outer end of the active buckle 5 can be designed as a single inclined surface or an arc surface formed by a combination of multiple inclined surfaces. The end of the inner pivot arm 9.3 is designed as an arc plate, and its radian matches the inclined surface or the arc surface of the active buckle 5. In this regard, the technical solution of this application designs the outer end of the active buckle 5 as an inclined surface or an arc surface, and the end of the inner pivot arm 9.3 as an arc plate, so that the contact surface between the inner pivot arm 9.3 and the active buckle 5 is smoother, reducing the frictional resistance. When the operating member 9 rotates, the end of the arc plate presses against the inclined surface or the arc surface of the active buckle 5, and drives the active buckle 5 to move along the inner wall of the housing 4 through sliding contact, thereby realizing a smoother operation. This structural design effectively solves the technical problems of large friction on the contact surface between the active buckle 5 and the inner pivot arm 9.3 and unsmooth operation, improving the convenience of operation and the user experience. Compared with the prior art, the technical solution of this application reduces the force required by the user during the operation process, reduces the hand fatigue feeling, and at the same time improves the fluency and reliability of the operation.

[0051] For example Figure 9As shown, the outer end of the active buckle plate 5 includes multiple rib plates 5.1 arranged in parallel, and the outer end faces of the rib plates 5.1 are constructed as inclined surfaces or arc surfaces. Specifically, the parallel arrangement of the rib plates 5.1 increases the structural strength of the outer end of the active buckle plate 5, while the design of the inclined surface or arc surface optimizes its contact effect with the inner pivot arm 9.3. As a preferred embodiment, the rib plates 5.1 can be made of metal materials and fixed to the outer end of the active buckle plate 5 by welding or riveting. In addition, the thickness and spacing of the rib plates 5.1 can be adjusted according to actual needs to further optimize the structural strength and contact effect. Thus, this technical solution significantly improves the structural strength of the outer end of the active buckle plate 5 by adding the rib plates 5.1, enabling it to withstand greater external forces during operation without being easily deformed. At the same time, the design of the inclined surface or arc surface reduces the frictional resistance between the active buckle plate 5 and the inner pivot arm 9.3, making the driving structure more stable and smooth during operation. Compared with the prior art, this solution not only solves the problem of laborious operation but also improves the overall performance and reliability of the driving structure.

[0052] Furthermore, a card slot 5.2 is provided on the inclined surface or arc surface of the active buckle plate 5; when the end of the inner pivot arm 9.3 presses against the card slot 5.2, the buckle heads 5.3 of the active buckle plate 5 and the driven buckle plate 6 are completely retracted into the housing 4. Specifically, the design of the card slot 5.2 can have various implementation methods. For example, the card slot 5.2 can be a concave arc slot, and its depth and shape match the end of the inner pivot arm 9.3. As a preferred embodiment, the depth of the card slot 5.2 can be slightly greater than the thickness of the end of the inner pivot arm 9.3, so as to provide a certain gap during pressing to avoid excessive friction. In addition, the edge of the card slot 5.2 can be designed with a smooth transition to reduce the resistance of the inner pivot arm 9.3 during sliding. The position of the card slot 5.2 can be set in the middle or near the end of the inclined surface or arc surface of the active buckle plate 5, and the specific position can be adjusted according to the operation requirements in actual applications. In this regard, through the design of the card slot 5.2, the end of the inner pivot arm 9.3 can accurately press against the card slot 5.2, thus ensuring that the buckle heads 5.3 of the active buckle plate 5 and the driven buckle plate 6 can be completely retracted into the housing 4. In this way, on the one hand, when the end of the inner pivot arm 9.3 presses against the card slot 5.2, it will give tactile and auditory feedback, enabling the user to perceive that the adjustment has been in place; on the other hand, when the depth of the card slot 5.2 is sufficient, it can be locked in the above state, and thus the quick-release device can be unlocked and removed in steps. Compared with the prior art, this solution not only improves the convenience and feel of operation but also enhances the stability and reliability of the device through the locking function of the card slot 5.2, effectively solving the problems of laborious operation and rough feel in the prior art.

[0053] As Figure 7 and 10As shown, the housing 4 includes a base 4.1 and a cover plate 4.2 covering the base 4.1. A through hole 4.5 is provided on the base 4.1. Arc-shaped grooves are respectively provided at the edges of the base 4.1 and the cover plate 4.2. When the base 4.1 and the cover plate 4.2 are assembled, the arc-shaped grooves are butted to form a hinge seat. The rotating shaft 9.1 of the operating member 9 is fitted into the hinge seat and can rotate around it. Among them, the design of the arc-shaped groove enables the base 4.1 and the cover plate 4.2 to be accurately butted during assembly to form a stable hinge seat. The shape and size of the hinge seat can be adjusted according to the specific requirements of the rotating shaft 9.1 to ensure that the rotating shaft 9.1 can be smoothly fitted and rotated. For example, the depth and width of the arc-shaped groove can match the diameter of the rotating shaft 9.1, thereby reducing the friction and wear of the rotating shaft 9.1 during rotation. In addition, the material of the arc-shaped groove can be selected as a material with relatively high wear resistance to extend the service life of the hinge seat. Specifically, the base 4.1 and the cover plate 4.2 are butted through the arc-shaped groove to form a hinge seat, providing a stable installation position for the rotating shaft 9.1 of the operating member 9. The rotating shaft 9.1 is fitted into the hinge seat, ensuring the stability and reliability of the operating member 9 during rotation. This design simplifies the installation process of the rotating shaft 9.1 and improves the durability and operating efficiency of the entire drive structure. For example, when the operating member 9 rotates, the hinge seat can effectively limit the axial and radial movement of the rotating shaft 9.1, thereby avoiding the failure of the drive structure caused by the loosening or deviation of the rotating shaft 9.1. Compared with the prior art, the technical solution of the present application forms a hinge seat by butting the arc-shaped grooves of the base 4.1 and the cover plate 4.2, significantly improving the installation and rotation stability of the rotating shaft 9.1 of the operating member 9. In the prior art, the rotating shaft 9.1 of the operating member 9 is usually directly installed on the side wall of the housing 4, and is prone to loosening or deviation of the rotating shaft 9.1 due to installation errors or long-term use, thereby affecting the reliability and operating efficiency of the drive structure. However, the technical solution of the present application simplifies the installation process of the rotating shaft 9.1 through the design of the hinge seat and improves the stability of the rotating shaft 9.1 during rotation, thereby enhancing the durability and operating efficiency of the entire drive structure.

[0054] As Figures 1 - 3, 12~16, the bottom plate 2 is slidably arranged at the upper end of the quick-release main unit 1, and one of the upper end surface of the quick-release main unit 1 and the lower end surface of the bottom plate 2 is provided with a positioning slot 12 extending along the sliding direction of the bottom plate 2, and the other is provided with a positioning assembly. A plurality of positioning teeth 12.1 are arranged at intervals in the positioning slot 12 along the sliding direction. The positioning assembly includes a latching tooth portion 13.1, and the latching tooth portion 13.1 can selectively engage in or withdraw from the positioning teeth 12.1. When the latching tooth portion 13.1 engages in any of the positioning teeth 12.1, the position of the bottom plate 2 relative to the quick-release main unit 1 is locked; when the latching tooth portion 13.1 withdraws from the positioning teeth 12.1, the bottom plate 2 can be slidably adjusted relative to the quick-release main unit 1. Among them, the extension direction of the positioning slot 12 is consistent with the sliding direction of the bottom plate 2, ensuring that the bottom plate 2 remains stable during the sliding process. The spacing of the positioning teeth 12.1 provides multiple fixed positions, so that the bottom plate 2 can be locked at different positions. The selective engagement or withdrawal operation of the latching tooth portion 13.1 is realized by manual or mechanical drive, specifically, the movement of the latching tooth portion 13.1 can be driven by toggling the operating component 9 or pressing a button. As a preferred embodiment, the latching tooth portion 13.1 can be designed as an elastic reset structure, which is automatically reset by the elastic force of the second reset spring 13.2, simplifying the operation steps.

[0055] Furthermore, the arrangement of the positioning slot 12 and the positioning assembly can be adjusted according to actual needs. For example, the positioning slot 12 can be arranged on the lower end surface of the base plate 2, while the positioning assembly is arranged on the upper end surface of the quick-release main unit 1, or vice versa. This design flexibility enables the structure to adapt to different models of motorcycle tank bag quick-release devices. Thus, the technical solution realizes the sliding adjustment and position locking of the base plate 2 through the cooperation of the positioning slot 12 and the positioning assembly. Compared with the prior art, the structure simplifies the operating steps, reduces the sliding resistance, and improves the fixing stability. Specifically, through the cooperation of the latching tooth portion 13.1 and the positioning tooth mouth 12.1, the base plate 2 does not need to apply a large external force during the sliding process, and the sliding process is smoother. At the same time, the spacing arrangement of the positioning tooth mouth 12.1 provides a plurality of fixed positions, so that the base plate 2 is not easy to loosen or shake after locking, especially in bumpy road conditions. It can still remain stable. The technical solution of the present application effectively solves the technical problems of cumbersome operation, uneven sliding resistance and insufficient fixing stability during the sliding adjustment process of the quick-release device of the motorcycle tank bag, thereby improving the user experience.

[0056] exist Figure 1 and 2In the specific solution shown, a slide rail hole 15 penetrating the upper and lower end faces of the bottom plate 2 is provided on the bottom plate 2; a sliding block 16 is fixedly connected to the upper end face of the quick-release main body unit 1, and the lower end of the sliding block 16 passes through the slide rail hole 15 and is fixedly connected to the quick-release main body unit 1; the sliding block 16 is in sliding fit with the slide rail hole 15 to guide the sliding direction of the bottom plate 2. The design of the slide rail hole 15 enables the sliding block 16 to slide smoothly inside it, ensuring the direction stability of the bottom plate 2 during the adjustment process. The fixed connection method of the sliding block 16 can be achieved through bolts, welding or other mechanical connection methods to ensure its firm connection with the quick-release main body unit 1. The shape of the slide rail hole 15 can be linear to adapt to different sliding requirements. The material of the sliding block 16 can be selected as wear-resistant and impact-resistant metal or plastic to improve its service life and reliability. By setting the cooperation between the slide rail hole 15 and the sliding block 16, the problem of unstable guiding of the sliding direction of the bottom plate 2 is solved. The slide rail hole 15 penetrates the upper and lower end faces of the bottom plate 2, the sliding block 16 is fixedly connected to the upper end face of the quick-release main body unit 1, and passes through the slide rail hole 15 and is fixedly connected to the quick-release main body unit 1. The sliding fit between the sliding block 16 and the slide rail hole 15 ensures the direction stability of the bottom plate 2 during the sliding process, avoiding deviation or jamming during the sliding process; at the same time, based on the cooperation between the sliding block 16 and the slide rail hole 15, it is possible to prevent the quick-release main body unit 1 from disconnecting from the bottom plate 2. Compared with the prior art, this technical solution simplifies the operation steps, improves the smoothness of the sliding process, enhances the fixing stability, and thus improves the user experience.

[0057] In a preferred embodiment, the positioning component is arranged on the quick-release main body unit 1, and the positioning chute 12 is arranged on the lower end surface of the bottom plate 2. That is, integrating the positioning component onto the quick-release main body unit 1 can simplify the structure of the bottom plate 2. Among them, the positioning component includes a tooth engaging part 13.1, and the tooth engaging part 13.1 can selectively engage or disengage from the positioning tooth notch 12.1 in the positioning chute 12. By arranging the positioning component on the quick-release main body unit 1 and arranging the positioning chute 12 on the lower end surface of the bottom plate 2, this design simplifies the structure and reduces the complexity of components. In a specific embodiment, the positioning component includes a displaceable block 13 arranged in a sliding manner, and a second return spring 13.2 for driving the displaceable block 13 to elastically return to its original position; the inner end of the displaceable block 13 is provided with a tooth engaging part 13.1, and the outer end extends to the side of the bottom plate 2 or the quick-release main body unit 1 as an operating end. In this embodiment, the sliding arrangement of the displaceable block 13 enables the user to easily push or pull the displaceable block 13 through the operating end, thereby controlling the engagement or disengagement of the tooth engaging part 13.1. The design of the second return spring 13.2 ensures that the displaceable block 13 can automatically return to its original position after operation, improving the convenience and stability of operation. The matching design of the tooth engaging part 13.1 and the positioning tooth notch 12.1 further enhances the stability of positioning and avoids the loosening problem caused by machining tolerances or wear in the traditional structure. Thus, through the cooperation of the displaceable block 13 and the second return spring 13.2 in this application, the convenient operation and stable fixation of the positioning component are achieved. Compared with the prior art, this application simplifies the operation steps. The user only needs to simply act on the operating end to achieve the sliding adjustment and position locking of the bottom plate 2, solving the problems of cumbersome operation steps and insufficient fixing stability in the traditional structure. In addition, the optimized design of the tooth engaging part 13.1 and the positioning tooth notch 12.1 further improves the accuracy and stability of positioning, ensuring the firm fixation of the motorcycle fuel tank bag under bumpy road conditions.

[0058] Further, an adjustment chute 13.3 is provided on the upper end surface of the quick-release main body unit 1, and a spring seat 13.4 is fixed in the adjustment chute 13.3; the displacement block 13 is slidably fitted in the adjustment chute 13.3, one end of the second return spring 13.2 abuts against the spring seat 13.4, and the other end abuts against the displacement block 13. The design of the adjustment chute 13.3 enables the displacement block 13 to be accurately guided during the sliding process, avoiding the deviation or jamming of the displacement block 13 during the sliding process. The setting of the spring seat 13.4 ensures the fixation of the second return spring 13.2. One end of the second return spring 13.2 abuts against the spring seat 13.4, and the other end abuts against the displacement block 13, enabling the displacement block 13 to automatically reset after sliding. This design not only improves the stability of the sliding of the displacement block 13, but also simplifies the installation and fixation of the second return spring 13.2, enhancing the reliability and operability of the entire sliding adjustment structure. Thus, the technical solution of the present application solves the problems of the fixation and guidance of the second return spring 13.2 during the sliding process of the displacement block 13 by providing the adjustment chute 13.3 and the spring seat 13.4. Compared with the prior art, this solution not only simplifies the structure, but also improves the stability of the sliding adjustment and the convenience of operation, significantly enhancing the user experience.

[0059] As Figures 12 - 16 shown, the tooth engaging portion 13.1 includes a plurality of movable teeth 13.5 arranged side by side, and the movable teeth 13.5 can synchronously engage with or disengage from the corresponding plurality of positioning tooth openings 12.1. By providing a plurality of movable teeth 13.5 and enabling them to synchronously engage with or disengage from the corresponding plurality of positioning tooth openings 12.1, the present application solves the problem of inaccurate cooperation between the movable teeth 13.5 and the positioning tooth openings 12.1. The side-by-side arrangement of the plurality of movable teeth 13.5 enables the tooth engaging portion 13.1 to contact a plurality of positioning tooth openings 12.1 simultaneously when engaging with or disengaging from the positioning tooth openings 12.1, thereby improving the cooperation accuracy between the tooth engaging portion 13.1 and the positioning tooth openings 12.1. This design ensures the stability of the bottom plate 2 during the sliding adjustment process, avoiding the problem of unstable sliding adjustment caused by inaccurate cooperation between a single tooth and the tooth opening. Through the synchronous action of the plurality of movable teeth 13.5, the present application achieves a more accurate and stable sliding adjustment effect. Compared with the prior art, the present application reduces the operation steps, improves the smoothness and fixed stability of the sliding adjustment, and is particularly suitable for occasions that require frequent adjustment.

[0060] Furthermore, a plurality of fixed teeth 12.2 are arranged side by side in the positioning chute 12, and a positioning tooth opening 12.1 is formed between two adjacent fixed teeth 12.2; the cross-section of the positioning tooth opening 12.1 is in a flared shape that gradually expands from the inside to the outside; the cross-section of the movable tooth 13.5 is in a conical shape with a gradually decreasing width from the root to the outer end; when the movable tooth 13.5 is fully engaged in the positioning tooth opening 12.1, the conical shape is perfectly adapted to the flared shape. In this solution, the shape design of the fixed teeth 12.2 and the movable teeth 13.5 is the key to ensuring precise cooperation. The arrangement of the fixed teeth 12.2 forms uniform intervals between the positioning tooth openings 12.1, and the flared shape of the positioning tooth openings 12.1 can effectively guide the insertion of the movable teeth 13.5. The conical shape of the movable teeth 13.5 gradually decreases from the root to the outer end, and this design enables the teeth to gradually adapt to the flared shape of the positioning tooth openings 12.1 during the insertion process and finally achieve perfect adaptation. Thus, through the shape matching of the fixed teeth 12.2 and the movable teeth 13.5, this technical solution ensures that the tooth portion 13.1 and the positioning tooth opening 12.1 are precisely and gradually guided to cooperate and finally pressed tightly, reducing the loosening phenomenon. Specifically, the conical shape of the movable teeth 13.5 is perfectly adapted to the flared shape of the positioning tooth openings 12.1, enabling the teeth to fit tightly after insertion and avoiding the loosening problem caused by shape mismatch. Compared with the prior art, this solution significantly improves the stability and precision of the sliding adjustment structure and solves the problems of inaccurate cooperation and easy loosening between the positioning tooth opening 12.1 and the tooth portion 13.1 in the sliding adjustment structure.

[0061] As Figure 12 and 14 shown, the heights of the fixed teeth 12.2 and the movable teeth 13.5 remain the same from the root to the outer end, or gradually decrease from the root to the outer end. Specifically, the height design of the fixed teeth 12.2 and the movable teeth 13.5 is the key to solving the problem of unsmooth or unstable engagement during the engagement process. In the first solution, by keeping the heights of the fixed teeth 12.2 and the movable teeth 13.5 the same from the root to the outer end, the contact surface during the engagement of the fixed teeth 12.2 and the movable teeth 13.5 can be ensured, improving the engagement positioning effect. In Figure 13 and 15In the second solution shown, by gradually reducing the height of the fixed teeth 12.2 and the movable teeth 13.5 from the root to the outer end, the displacement of the displacement block 13 can be reduced during the process of the tooth portion 13.1 withdrawing from the positioning tooth opening 12.1. The first solution requires the movable teeth 13.5 to completely withdraw from the positioning tooth opening 12.1 before sliding, while the second solution only needs to move the displacement block 13 until the sum of the heights of the fixed teeth 12.2 and the movable teeth 13.5 is less than the height of the root to allow sliding. Thus, by optimizing the height design of the fixed teeth 12.2 and the movable teeth 13.5, the present application effectively solves the technical problem of unsmooth or unstable engagement caused by height changes during the engagement process. Compared with the prior art, the technical solution of the present application simplifies the operation steps, improves the adjustment efficiency while ensuring the engagement stability, and has remarkable practicality and innovation.

[0062] As Figures 12 - 15 shown, a plurality of feedback grooves 18 are provided along the extending direction of the positioning sliding groove 12, and the feedback grooves 18 are located in the extending direction of the tooth opening of the positioning tooth opening 12.1; an elastic feedback member is provided at the inner end of the positioning assembly; when the bottom plate 2 slides, the elastic feedback member sequentially enters or exits the feedback grooves 18 and generates a tactile or auditory feedback during the movement. Specifically, the feedback grooves 18 can be designed to form a concave or convex structure on the side wall or bottom of the positioning sliding groove 12, and its shape can be rectangular, arc-shaped or other geometric shapes to cooperate with the elastic feedback member. In this regard, by providing a plurality of feedback grooves 18 in the positioning sliding groove 12 and an elastic feedback member at the inner end of the positioning assembly, the function of providing tactile or auditory feedback during the sliding process of the bottom plate 2 is realized. The feedback grooves 18 are provided in the extending direction of the positioning tooth opening 12.1, so that the elastic feedback member can sequentially enter or exit the feedback grooves 18 during the sliding process, thereby generating a feedback signal. This design not only enhances the intuitiveness of user operation, but also improves the accuracy of sliding adjustment and the user experience. Compared with the prior art, this solution simplifies the operation steps, reduces the sliding resistance, improves the fixing stability, and can effectively prevent the fuel tank package from being displaced especially under bumpy road conditions.

[0063] Furthermore, the elastic feedback component includes an elastic corrugated plate 14. Both ends of the elastic corrugated plate 14 are fixed to the inner ends of the displacement block 13, and at least one feedback protrusion 14.1 matching the feedback groove 18 is provided. As an elastic element, the elastic corrugated plate 14 has both ends fixed to the inner ends of the displacement block 13 to ensure stable movement following the displacement block 13 during the sliding process. The matching design of the feedback protrusion 14.1 and the feedback groove 18 enables the feedback protrusion 14.1 to sequentially enter or exit the feedback groove 18 when the bottom plate 2 slides, thereby generating tactile or auditory feedback. Specifically, the elastic corrugated plate 14 can be made of metal or polymer materials, and its shape can be wavy, serrated, or other structures that can provide elasticity. The shape of the feedback protrusion 14.1 can be hemispherical, conical, or other shapes that can form a good fit with the feedback groove 18. As a preferred embodiment, multiple feedback protrusions 14.1 can be provided on the elastic corrugated plate 14 to increase the frequency and intensity of the feedback. Through the cooperation of the elastic corrugated plate 14 and the feedback protrusion 14.1, the present application effectively solves the problem of lack of feedback during the sliding adjustment process and improves the user experience. Specifically, when the bottom plate 2 slides, the feedback protrusion 14.1 sequentially enters or exits the feedback groove 18, generating obvious tactile or auditory feedback, enabling the user to clearly perceive the sliding process. This design not only improves the intuitiveness of the operation but also reduces the possibility of misoperation. Compared with the prior art, the present application significantly improves the smoothness and stability of the sliding adjustment by introducing the elastic feedback component, enabling the user to more easily and accurately complete the position adjustment during use.

[0064] With the above sliding adjustment structure, during use, it can be considered that the operating end of the displacement block 13 is pressed, causing the second return spring 13.2 to be compressed and the tooth engaging portion 13.1 to withdraw from the positioning tooth opening 12.1 in the positioning sliding groove 12. At this time, the fuel tank package can be pushed and pulled with the other hand to achieve position adjustment. During this process, the elastic feedback component sequentially enters or exits the feedback groove 18 and generates tactile or auditory feedback during the movement. When the appropriate position is reached, both hands can be released, and the tooth engaging portion 13.1 can be pressed into the positioning tooth opening 12.1 in the positioning sliding groove 12 under the action of the second return spring 13.2 to achieve positioning. It can be seen that the above solution does not require removing the quick-release device and the fuel tank package thereon during adjustment, but can directly perform front-back adjustment on the motorcycle. However, for the related patents described in the background art, although sliding adjustment can be achieved, it is necessary to remove the quick-release device and the fuel tank thereon from the vehicle for adjustment, which is troublesome to operate.

[0065] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention without departing from the principles and purposes of the present invention.
