Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, and in particular to a drive structure on a quick-release device for a motorcycle fuel tank bag. Background Technology

[0002] Existing quick-release devices for motorcycle fuel tank bags (such as Chinese patents CN220009989U and CN221541817U) use a pull strap as the core operating component to drive the locking assembly. Specifically, the user needs to forcefully pull the pull strap to move the latch lever. The top post at the bottom of the latch lever then slides within the triangular latch plate hole, forcing the two symmetrically arranged latch plates to move towards each other, thereby causing the latch head to retract into the housing and unlock the fuel tank bag. However, this pull strap-dependent driving method has the following significant drawbacks: it is laborious to operate and feels stiff. The user needs to apply considerable pulling force to overcome the multi-directional friction of the top post within the triangular latch plate hole, resulting in a laborious unlocking action, which can easily cause hand fatigue, especially during frequent operation. In addition, the combination of the flexible material of the pull strap and the rigid transmission of the latch lever further exacerbates the stiffness during operation.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0007] Furthermore, this application also proposes that the operating component is driven and connected to the active buckle plate; a synchronous gear is rotatably arranged inside the housing; and racks are respectively provided at the inner ends of the active buckle plate and the driven buckle plate, with the racks meshing with the synchronous gears, so that when the operating component drives the active buckle plate to move, the synchronous gears drive the driven buckle plate to move synchronously.

[0008] Furthermore, this application also proposes that the rack at the inner end of the active buckle plate and the rack at the inner end of the driven buckle plate are respectively meshed on both sides of the synchronous gear, and the active buckle plate and the driven buckle plate move in opposite directions.

[0009] Furthermore, this application also proposes that the operating component drives the active buckle plate and the driven buckle plate to move towards each other, causing the buckle head to retract into the housing; the elastic force of the return spring drives the active buckle plate and the driven buckle plate to move away from each other, causing the buckle head to extend out of the housing.

[0010] Furthermore, this application also proposes that the inclined surface of the inner pivot arm presses against the outer end of the active buckle plate; when the operating component rotates, the inner pivot arm drives the active buckle plate to move along the inner wall of the housing through sliding contact.

[0011] Furthermore, this application also proposes that the length of the lever plate is greater than the length of the inner pivot arm, forming a force-saving lever structure.

[0012] Furthermore, this application also proposes that the outer end of the active buckle plate is constructed as a slope or arc surface, and the end of the inner pivot arm is an arc plate; the end of the arc plate presses against the slope or arc surface of the active buckle plate.

[0013] Furthermore, this application also proposes that a slot is provided on the inclined or arc-shaped surface of the active buckle plate; when the end of the inner pivot arm is pressed against the slot, the buckles of the active buckle plate and the driven buckle plate are completely retracted into the housing.

[0014] Furthermore, this application also proposes that the outer end of the active buckle plate includes multiple parallel stiffeners, and the outer end face of the stiffeners is constructed as an inclined surface or an arc surface.

[0015] Furthermore, this application also proposes that the housing includes a base plate and a cover plate covering the base plate, and the through hole is provided on the base plate; the edges of the base plate and the cover plate are respectively provided with arc-shaped grooves, and when the base plate and the cover plate are assembled, the arc-shaped grooves are joined to form a hinge seat; the rotating shaft of the operating component is embedded in the hinge seat and can rotate around it.

[0016] As can be seen from the above, the driving structure and operating method of the quick-release device for a motorcycle fuel tank bag provided in this application realize the rapid extension and retraction of the buckle by setting up operating components, synchronous gears and return springs, etc., solving the problems of laborious operation and stiff feel in the prior art, and has the advantages of labor-saving operation and smooth feel.

Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0027] like Figures 1-4 As shown, this embodiment proposes a drive structure for a quick-release device on a motorcycle fuel tank bag, including a housing and a locking assembly disposed inside the housing. Multiple through holes 3 are provided on the side wall of the housing. The locking assembly includes an active locking plate 4 and a driven locking plate 5 slidably disposed within the housing, an operating component 6 for driving the active locking plate 4 and the driven locking plate 5 to move, and a return spring 7. The outer ends of the active locking plate 4 and the driven locking plate 5 are provided with buckles 8, which can extend or retract from the through holes 3. The operating component 6 includes a rotating shaft 9 rotatably disposed on the housing, a lever 10 located on the outer side of the housing, and an inner pivot arm 11 located on the inner side of the housing. The lever 10 and the inner pivot arm 11 are fixedly connected or integrally formed. When an external force is applied to the lever 10, the operating component 6 rotates around the rotating shaft 9, directly or indirectly driving the active locking plate 4 and the driven locking plate 5 to slide through the inner pivot arm 11. The rotating shaft 9 of the operating component 6 can be fixed to the housing by bearings or bushings to ensure smooth rotation. The connection between the lever plate 10 and the inner pivot arm 11 can be achieved by welding, bolting, or integral molding to enhance structural stability. The end of the inner pivot arm 11 can be designed as a bevel or arc surface 17 to better contact the outer end 16 of the active buckle plate 4, thereby more effectively driving the buckle plate to slide. The return spring 7 can be disposed between the active buckle plate 4 and the driven buckle plate 5, or separately disposed between the buckle plate (including the active buckle plate 4 and the driven buckle plate 5) and the housing, to ensure that the buckle head 8 can automatically return to its original position when no external force is applied.

[0028] This technical solution, through the setting of a rotating operating component 6 and the linkage between the lever 10 and the inner pivot arm 11, allows the user to drive the active buckle plate 4 and the driven buckle plate 5 to slide by rotating the lever 10, thereby extending or retracting the buckle head 8. This design avoids the multi-directional friction of traditional pull-tab operation methods, simplifies the operation process, and improves the convenience and feel of operation. The structural design of the housing and locking assembly ensures the stability and reliability of the device, while the setting of the return spring 7 ensures that the buckle head 8 automatically resets when no external force is applied. The overall solution effectively solves the problems of laborious operation and stiff feel in the prior art, improving the user experience.

[0029] like Figure 1 and 2 As shown, the operating component 6 is driven and connected to the active buckle plate 4; a synchronous gear 12 is rotatably installed inside the housing; racks 13 are respectively provided at the inner ends of the active buckle plate 4 and the driven buckle plate 5, and the racks 13 mesh with the synchronous gear 12, so that when the operating component 6 drives the active buckle plate 4 to move, the synchronous gear 12 drives the driven buckle plate 5 to move synchronously. Specifically, the rotation shaft of the synchronous gear 12 can be fixed on the inner wall of the housing, and the diameter and number of teeth of the gear are designed according to actual needs to ensure the synchronous movement accuracy of the active buckle plate 4 and the driven buckle plate 5. The racks 13 at the inner ends of the active buckle plate 4 and the driven buckle plate 5 can be designed as straight lines or curves, and the tooth pitch of the rack 13 and the tooth pitch of the gear must match to ensure smooth meshing. In addition, the material of the synchronous gear 12 can be a high-strength wear-resistant material, such as stainless steel or engineering plastic, to extend its service life. By setting a synchronizing gear 12, racks 13 are respectively provided at the inner ends of the active buckle plate 4 and the driven buckle plate 5. The racks 13 mesh with the synchronizing gear 12. When the operating component 6 drives the active buckle plate 4 to move, the synchronizing gear 12 drives the driven buckle plate 5 to move synchronously, thereby realizing the synchronous movement of the active buckle plate 4 and the driven buckle plate 5. This design simplifies the drive structure and improves the convenience and efficiency of operation. Compared with the prior art, the technical solution of this application avoids the laboriousness and stiffness caused by relying on the pull belt operation, and realizes a smoother and more efficient synchronous movement of the buckles through gear transmission, significantly improving the user experience.

[0030] Furthermore, the rack 13 at the inner end of the driving plate 4 and the rack 13 at the inner end of the driven plate 5 respectively mesh with the two sides of the synchronizing gear 12, and the driving plate 4 and the driven plate 5 move in opposite directions. Specifically, the inner ends of the driving plate 4 and the driven plate 5 are respectively provided with racks 13, which mesh with the two sides of the synchronizing gear 12. The rotation of the synchronizing gear 12 will drive the driving plate 4 and the driven plate 5 to move synchronously, but in opposite directions. For example, when the driving plate 4 moves to the left, the driven plate 5 will move to the right, and vice versa. This design can be implemented in various ways. For example, the diameter and number of teeth of the synchronizing gear 12 can be adjusted according to actual needs to ensure that the moving speed and direction of the driving plate 4 and the driven plate 5 meet the design requirements. To address this issue, this technical solution utilizes the meshing of the synchronizing gear 12 to ensure that the driving buckle 4 and the driven buckle 5 move in opposite directions during synchronous movement, thus resolving the technical problem of their opposite directions during synchronous movement. Specifically, when the operating component 6 drives the driving buckle 4 to move, the synchronizing gear 12 drives the driven buckle 5 to move synchronously, but in opposite directions. This design ensures that the buckle 8 can effectively extend or retract from the housing, improving operational convenience and reliability. Compared to existing technologies, this technical solution, through the meshing of the synchronizing gear 12, avoids the complex structure and operational inconvenience caused by the operating component 6 directly driving the driven buckle 5, simplifying the structure and improving operational efficiency and stability.

[0031] In the specific design, the operating component 6 drives the active buckle plate 4 and the driven buckle plate 5 to move towards each other, causing the buckle head 8 to retract into the housing; the elastic force of the return spring 7 drives the active buckle plate 4 and the driven buckle plate 5 to move away from each other, causing the buckle head 8 to extend out of the housing. The operating component 6 includes a rotating shaft 9 rotatably mounted on the housing, a lever plate 10 located on the outer side of the housing, and an inner pivot arm 11 located on the inner side of the housing. The lever plate 10 and the inner pivot arm 11 are fixedly connected or integrally formed. When an external force is applied to the lever plate 10, the operating component 6 rotates around the rotating shaft 9, directly or indirectly driving the active buckle plate 4 and the driven buckle plate 5 to slide through the inner pivot arm 11. The inclined surface at the end of the inner pivot arm 11 presses against the outer end 16 of the active buckle plate 4. This inclined surface pressing refers to an inclined surface engagement method that can change the direction of the force. Specifically, this design can be described below by constructing the outer end 16 of the active buckle plate 4 as an inclined surface or an arc-shaped surface 17 to achieve the inclined surface pressing. When the operating component 6 rotates, the inner pivot arm 11 slides and drives the active buckle plate 4 to move along the inner wall of the housing, thus converting the rotational force of the inner pivot arm 11 into the movement of the active buckle plate 4. The operating component 6 drives the active buckle plate 4 and the driven buckle plate 5 to move towards each other, causing the buckle head 8 to retract into the housing, thereby achieving the unlocking function. The elastic force of the return spring 7 drives the active buckle plate 4 and the driven buckle plate 5 to move away from each other, causing the buckle head 8 to extend out of the housing, achieving the locking function. This design, through the cooperation of the operating component 6 and the return spring 7, achieves automatic extension and retraction of the buckle head 8, simplifying the operation steps and improving ease of use. Compared with the prior art, the operating component 6 of this application adopts a rigid transmission structure, avoiding the problems of laborious operation and stiff feel caused by flexible pull straps, significantly improving the smoothness and comfort of operation.

[0032] To address this, the technical solution of this application optimizes the contact method between the inner pivot arm 11 and the active buckle plate 4, achieving a smoother driving effect. Specifically, the sliding contact between the inner pivot arm 11 and the outer end 16 of the active buckle plate 4 reduces the multi-directional friction in the traditional pull-belt driving method, making the driving process more effortless and the operation smoother. Compared with the prior art, this application avoids the stiffness and laborious operation problems of the pull-belt driving method, ensuring that the force transmission is more direct and efficient.

[0033] Furthermore, the length of the lever 10 is greater than the length of the inner pivot arm 11, forming a force-saving lever structure. Specifically, the lever 10 is fixedly connected to or integrally formed with the inner pivot arm 11. When an external force is applied to the lever 10, the operating component 6 rotates around the pivot axis 9, directly or indirectly driving the active latch plate 4 and the driven latch plate 5 to slide through the inner pivot arm 11. The greater length of the lever 10 compared to the inner pivot arm 11 allows the user to drive the inner pivot arm 11 with less force when operating the lever 10, thereby indirectly driving the active latch plate 4 and the driven latch plate 5 to slide. As a preferred embodiment, the lever 10 can be designed as a long strip, the length of which can be adjusted according to actual needs to ensure maximum force-saving effect. The inner pivot arm 11 is relatively short to enhance the force-saving effect of the lever. In addition, the connection between the lever 10 and the inner pivot arm 11 can be achieved through welding, bolting, or integral forming, etc., to ensure structural stability and durability. Therefore, through this force-saving lever structure design, when operating the lever 10, the user can drive the inner pivot arm 11 with a smaller force, thereby indirectly driving the active latch plate 4 and the driven latch plate 5 to slide. This design effectively reduces the force required for user operation, improves the operating feel, and solves the problems of laborious operation and stiff 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 in frequent operation, effectively reducing hand fatigue.

[0034] like Figure 4 As shown, the outer end 16 of the active buckle plate 4 is constructed as a slope or arc surface 17, and the end of the inner pivot arm 11 is an arc plate; the end of the arc plate presses against the slope or arc surface 17 of the active buckle plate 4. The outer end 16 of the active buckle plate 4 can be designed as a single slope or as an arc surface 17 formed by a combination of multiple slopes. The end of the inner pivot arm 11 is designed as an arc plate, the curvature of which matches the slope or arc surface 17 of the active buckle plate 4. In this respect, the technical solution of this application, by designing the outer end 16 of the active buckle plate 4 as a slope or arc surface 17 and the end of the inner pivot arm 11 as an arc plate, makes the contact surface between the inner pivot arm 11 and the active buckle plate 4 smoother and reduces frictional resistance. When the operating component 6 rotates, the end of the arc plate presses against the slope or arc surface 17 of the active buckle plate 4, and drives the active buckle plate 4 to move along the inner wall of the housing through sliding contact, thereby achieving smoother operation. This structural design effectively solves the technical problem of high friction and unsmooth operation between the active latch plate 4 and the inner pivot arm 11, improving the convenience of operation and user experience. Compared with the prior art, the technical solution of this application reduces the force required by the user during operation, reduces hand fatigue, and improves the smoothness and reliability of operation.

[0035] For example Figure 4As shown, the outer end 16 of the active buckle plate 4 includes multiple parallel stiffeners 20, the outer end faces of which are constructed as inclined or curved surfaces 17. Specifically, the parallel arrangement of the stiffeners 20 increases the structural strength of the outer end 16 of the active buckle plate 4, while the design of the inclined or curved surfaces 17 optimizes its contact effect with the inner pivot arm 11. As a preferred embodiment, the stiffeners 20 can be made of metal and fixed to the outer end 16 of the active buckle plate 4 by welding or riveting. Furthermore, the thickness and spacing of the stiffeners 20 can be adjusted according to actual needs to further optimize structural strength and contact effect. Thus, this technical solution significantly improves the structural strength of the outer end 16 of the active buckle plate 4 by adding stiffeners 20, enabling it to withstand greater external forces during operation without easily deforming. At the same time, the design of the inclined or curved surfaces 17 reduces the frictional resistance between the active buckle plate 4 and the inner pivot arm 11, making the drive structure more stable and smooth during operation. Compared with existing technologies, this solution not only solves the problem of laborious operation, but also improves the overall performance and reliability of the drive structure.

[0036] Furthermore, a slot 19 is formed on the inclined or arc-shaped surface 17 of the active buckle plate 4; when the end of the inner pivot arm 11 is pressed against the slot 19, the buckle heads 8 of the active buckle plate 4 and the driven buckle plate 5 are completely retracted into the housing. Specifically, the design of the slot 19 can be implemented in various ways. For example, the slot 19 can be a recessed arc-shaped groove whose depth and shape match the end of the inner pivot arm 11. As a preferred embodiment, the depth of the slot 19 can be slightly greater than the thickness of the end of the inner pivot arm 11, thereby providing a certain gap when pressed against and avoiding excessive friction. In addition, the edge of the slot 19 can be designed to have a smooth transition to reduce the resistance of the inner pivot arm 11 during sliding. The position of the slot 19 can be set in the middle or near the end of the inclined or arc-shaped surface 17 of the active buckle plate 4, and the specific position can be adjusted according to the operational requirements of the actual application. To address this, the technical solution utilizes the design of the slot 19, allowing the end of the inner pivot arm 11 to be accurately pressed against the slot 19, thus ensuring that the buckles 8 of the active and driven buckles 4 and 5 can be fully retracted into the housing. In this way, tactile and audible feedback is provided when the end of the inner pivot arm 11 is pressed against the slot 19, allowing the user to perceive that the adjustment is complete; furthermore, when the slot 19 is deep enough, it can be locked in the aforementioned state, allowing for step-by-step unlocking and removal of the quick-release device. Compared to existing technologies, this solution not only improves the ease of operation and feel but also enhances the stability and reliability of the device through the locking function of the slot 19, effectively solving the problems of laborious operation and stiff feel in existing technologies.

[0037] like Figure 1As shown, the housing includes a base plate 21 and a cover plate 22 covering the base plate 21, with a through hole 3 on the base plate 21. The edges of the base plate 21 and the cover plate 22 are respectively provided with arc-shaped grooves 23. When the base plate 21 and the cover plate 22 are assembled, the arc-shaped grooves 23 align to form a hinge seat. The rotating shaft 9 of the operating component 6 is embedded in the hinge seat and can rotate around it. The design of the arc-shaped groove 23 allows the base plate 21 and the cover plate 22 to precisely align during assembly, forming 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 to ensure that the rotating shaft 9 can be smoothly embedded and rotate. For example, the depth and width of the arc-shaped groove 23 can match the diameter of the rotating shaft 9, thereby reducing friction and wear during rotation. Furthermore, the material of the arc-shaped groove 23 can be a material with high wear resistance to extend the service life of the hinge seat. Specifically, the base plate 21 and the cover plate 22 are joined together by an arc-shaped groove 23 to form a hinge seat, providing a stable mounting position for the rotating shaft 9 of the operating component 6. The rotating shaft 9 is embedded within the hinge seat, ensuring the stability and reliability of the operating component 6 during rotation. This design simplifies the installation process of the rotating shaft 9 while improving the durability and operational efficiency of the entire drive structure. For example, when the operating component 6 rotates, the hinge seat effectively restricts the axial and radial movement of the rotating shaft 9, thereby preventing drive structure failure due to loosening or misalignment of the rotating shaft 9. Compared with the prior art, the technical solution of this application, by joining the base plate 21 and the cover plate 22 by an arc-shaped groove 23 to form a hinge seat, significantly improves the installation and rotational stability of the rotating shaft 9 of the operating component 6. In the prior art, the rotating shaft 9 of the operating component 6 is usually directly mounted on the side wall of the housing, which is prone to loosening or misalignment due to installation errors or long-term use, thus affecting the reliability and operational efficiency of the drive structure. The technical solution of this application simplifies the installation process of the rotating shaft 9 through the design of the hinge seat, and also improves the stability of the rotating shaft 9 during rotation, thereby improving the durability and operating efficiency of the entire drive structure.
