Description

Technical Field

[0001] This utility model relates to the field of vehicle cargo accessories technology, and more specifically, to a fuel tank adapter and a quick-release motorcycle fuel tank. Background Technology

[0002] A fuel tank bag is a bag attached to the motorcycle's fuel tank. For motorcycles with limited storage space, a fuel tank bag can significantly increase carrying capacity, making it suitable for storing small tools, power banks, rain gear, etc. Fuel tank bags obstruct the motorcycle's fuel filler neck and need to be removed for refueling. Therefore, current fuel tank bags are usually designed to be detachable, for example, by using straps or attaching buckles to the fuel tank. Current fuel tank bags are inconvenient to install, cumbersome to assemble, and difficult to disassemble, making quick installation and removal impossible. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of current fuel tank bag adapters, which are inconvenient to connect and cannot be quickly installed or disassembled, and to provide a fuel tank bag adapter component and a quick-release motorcycle fuel tank bag. This invention has a simple structure, and the installation and disassembly process is convenient and effective, enabling quick installation and disassembly and improving ease of use.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A fuel tank bag adapter assembly includes a first adapter for connecting a fuel tank cap and a second adapter for connecting a bag body. The first adapter has a protrusion, and the second adapter has a slot that mates with the protrusion. The protrusion and the slot are rotatably engaged. The first adapter also has a first magnetic element, and the second adapter also has a second magnetic element.

[0006] In use, the first adapter is fixed to the fuel tank cap, and one side of the second adapter is fixedly connected to the fuel tank bag. Quick installation and disassembly are achieved through two connection methods: First, when the first and second adapters are close together, the first and second magnetic attachments quickly attract them together. This provides temporary fixation for both adapters, and since the fuel tank bag obstructs the installation view, the magnetic attraction also allows for quick alignment of the first and second adapters, facilitating easy positioning. The relative positions of the first and second adapters are determined without repeated observation of alignment, facilitating the next step of rotation and engagement. Once the first and second adapters are aligned, rotating the second adapter causes its groove to rotate relative to the first adapter. The protrusion on the first adapter engages with the groove during rotation, thus securing the first and second adapters and preventing the motorcycle fuel tank from falling off during driving. When leaving the vehicle, rotating the second adapter again disengages the groove and protrusion, enabling quick disassembly and easy removal of the fuel tank. This invention features a simple structure, convenient and efficient installation and disassembly, and improved ease of use.

[0007] Furthermore, the slot is an arc-shaped slot, with openings at the top and both ends. The width of the top opening of the arc-shaped slot is smaller than the width of the bottom of the arc-shaped slot. The protrusion enters and exits from the end opening of the arc-shaped slot, and the end of the protrusion is rotatably limited within the arc-shaped slot.

[0008] This invention adopts an open arc-shaped groove snap-fit ​​method, which allows the protrusion to enter and exit from both ends of the arc-shaped groove, increasing the snap-fit ​​entry points and thus improving the snap-fit ​​flexibility. The end of the protrusion is limited in the arc-shaped groove and can rotate clockwise and counterclockwise along the arc along the top opening of the arc-shaped groove. The structure is simple and the snap-fit ​​fastening effect is good.

[0009] Furthermore, the second adapter includes a first ring for connecting a bag, a second ring coaxially fixed to the first ring and having an outer diameter smaller than the first ring, a first arc-shaped block distributed circumferentially on the outer periphery of the first ring, the end width of the first arc-shaped block being greater than the width of the root of the first arc-shaped block; the sidewall between the first arc-shaped block and the second ring forms the arc-shaped groove, and the first magnetic suction member is disposed on the second ring.

[0010] The second adapter of this utility model consists of two units, which facilitates production and manufacturing. The arc groove is formed by the side wall between the first arc block on the first ring and the second ring, which simplifies the processing difficulty and facilitates the fixation of the fuel tank bag body. Secondly, the ring shape can reduce the weight of the entire device and improve the user experience.

[0011] Furthermore, the first arc-shaped block and the first circular ring are integrally formed.

[0012] Furthermore, the protrusion is a second arc-shaped block that matches the curvature of the arc-shaped groove.

[0013] Furthermore, the end of the second arc-shaped block is provided with a rounded transition structure and / or a clearance portion. The clearance portion can be located on one side of the junction of the first ring and the second ring, so that the protrusion will not directly contact the two, reducing friction and improving the smoothness of rotation.

[0014] Furthermore, the first adapter is an open ring, and the protrusion is located on the circumferential direction of the outer periphery of the open ring. Secondly, designing it as an open ring can reduce the weight of the entire device and improve the user experience. Without affecting the rotational engagement effect of the protrusion and the slot, the specific structure and shape of the open ring of the first adapter can be changed, all of which are within the scope of protection of this application.

[0015] Furthermore, the protrusion is integrally formed with the first adapter.

[0016] Furthermore, the number of arc-shaped grooves is three, and the number of protrusions is also three. Each protrusion is located in a relative position between two adjacent arc-shaped grooves. The arc-shaped grooves are evenly distributed along the circumference of the second snap-fit ​​member, and the protrusions are evenly distributed along the circumference of the first adapter member.

[0017] Furthermore, the protrusion moves in and out of the arc-shaped groove through the gap between two adjacent arc-shaped grooves.

[0018] Furthermore, the number of the first magnetic attractors is twice the number of the second magnetic attractors. The first magnetic attractors are distributed at relative positions between each of the arc-shaped grooves and between two adjacent arc-shaped grooves, while the second magnetic attractors are located at relative positions between the protrusions. Here, "relative positions" means that the two are located on the same radius line of the same concentric circle, and may overlap or be located on different radii.

[0019] This invention sets the number of first magnetic suction components to twice the number of second magnetic suction components. This not only solves the positioning problem of the first adapter and the second snap-fit ​​component when they are docked, but also allows the second magnetic suction component to be attracted to another first magnetic suction component after they are snapped together. This provides a second layer of fixed attraction after the snap-fit, reducing the shaking of the bag when riding a motorcycle and improving the connection stability.

[0020] Furthermore, both the first and second magnetic attractors are strong magnets.

[0021] Furthermore, it also includes a pad located between the first adapter and the motorcycle fuel tank cap. The pad has mounting holes for threaded connection with the screw holes of the motorcycle fuel tank cap. Since the fuel tank cap is not a regular plane and has a certain protrusion, directly fixing the first connector would result in an unsupported surface, leading to uneven stress and deformation. The pad, placed between the motorcycle fuel tank cap and the first adapter, eliminates the height difference between the two surfaces, making threaded fixing less prone to deformation. This enhances the stability of the connection between the first connector and the motorcycle fuel tank cap, while also resulting in a smoother and more aesthetically pleasing installation, providing better support and improved stability.

[0022] This utility model also provides a quick-release motorcycle fuel tank bag, including a bag body and a fuel tank bag adapter assembly as described above, wherein the bag body is fixed on the second adapter assembly.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] In use, the first adapter is fixed to the fuel tank cap, and one side of the second adapter is fixedly connected to the fuel tank bag. Quick installation and disassembly are achieved through two connection methods: First, when the first and second adapters are close together, the first and second magnetic attachments quickly attract them together. This provides temporary fixation for both adapters, and since the fuel tank bag obstructs the installation view, the magnetic attraction also allows for quick alignment of the first and second adapters, facilitating easy positioning. The relative positions of the first and second adapters are determined without repeated observation of alignment, facilitating the next step of rotation and engagement. Once the first and second adapters are aligned, rotating the second adapter causes its groove to rotate relative to the first adapter. The protrusion on the first adapter engages with the groove during rotation, thus securing the first and second adapters and preventing the motorcycle fuel tank from falling off during driving. When leaving the vehicle, rotating the second adapter again disengages the groove and protrusion, enabling quick disassembly and easy removal of the fuel tank. This invention features a simple, convenient, and effective structure, enabling quick assembly and disassembly and improving ease of use. Attached Figure Description

[0032] Example 1

[0033] like Figures 1 to 2 The first embodiment shown is a fuel tank bag adapter assembly, which includes a first adapter 1 for connecting the fuel tank cap and a second adapter 2 for connecting the bag body 100. The first adapter 1 is provided with a protrusion 11, and the second adapter 2 is provided with a slot 20 that cooperates with the protrusion 11. The protrusion 11 and the slot 20 are rotatably engaged. The first adapter 1 is also provided with a first magnetic suction member 12, and the second adapter 2 is also provided with a second magnetic suction member 21.

[0034] like Figure 1 and Figure 2 As shown, the slot 20 is an arc-shaped slot with openings at the top and both ends. The width of the top opening of the arc-shaped slot is smaller than the width of the bottom of the arc-shaped slot. The protrusion 11 enters and exits from the end opening of the arc-shaped slot, and the end of the protrusion 11 is rotated and limited in the arc-shaped slot.

[0035] like Figure 2As shown, an open arc groove snap-fit ​​method is adopted, so that the protrusion 11 can enter and exit from both ends of the arc groove, increasing the snap-fit ​​entry point and thus improving the snap-fit ​​flexibility. The end of the protrusion 11 is limited in the arc groove and can rotate clockwise and counterclockwise along the arc along the top opening of the arc groove. The structure is simple and the snap-fit ​​fastening effect is good.

[0036] like Figure 1 As shown, the second adapter 2 includes a first ring 22 for connecting a bag, a second ring 23 coaxially fixed on the first ring 22 and having an outer diameter smaller than the first ring 22, a first arc-shaped block 221 circumferentially distributed on the outer periphery of the first ring 22, the end width of the first arc-shaped block 221 being greater than the width of the root of the first arc-shaped block 221; an arc-shaped groove is formed on the sidewall between the first arc-shaped block 221 and the second ring 23, and a first magnetic suction member 12 is provided on the second ring 23.

[0037] The second adapter 2 in this embodiment consists of two units, which facilitates production and manufacturing. The arc groove formed by the sidewall between the first arc block 221 on the first ring 22 and the second ring 23 simplifies the processing difficulty and facilitates the fixation of the fuel tank bag body 100. Secondly, the ring shape can reduce the weight of the entire device and improve the user experience.

[0038] In this embodiment, the first arc-shaped block 221 and the first ring 22 are integrally formed.

[0039] In this embodiment, the protrusion 11 is a second arc-shaped block that matches the curvature of the arc-shaped groove.

[0040] like Figure 3 As shown, the end of the second arc-shaped block is provided with an arc transition structure 111 and a clearance part 112.

[0041] In this embodiment, the arc transition structure 111 is disposed on one side of the corner of the first arc block 221, and the avoidance part 112 is disposed on one side of the junction of the first ring 22 and the second ring 23. In this way, the protrusion 11 will not directly contact the two, reducing friction and improving the smoothness of rotation.

[0042] like Figure 1 As shown, the first adapter 1 is an open ring, with the protrusion 11 located on the circumferential direction of the outer periphery of the open ring. Furthermore, designing it as an open ring can reduce the weight of the entire device and improve the user experience. Without affecting the rotational engagement effect of the protrusion 11 and the slot 20, the specific structure and shape of the open ring of the first adapter 1 can be changed, all within the scope of protection of this application.

[0043] In this embodiment, the protrusion 11 is integrally formed with the first adapter 1.

[0044] like Figure 1 As shown, there are three arc-shaped grooves and three protrusions 11, with each protrusion 11 located in the gap between two adjacent arc-shaped grooves. The arc-shaped grooves are evenly distributed along the circumference of the second snap-fit ​​member, and the protrusions 11 are evenly distributed along the circumference of the first adapter 1.

[0045] In this embodiment, the protrusion 11 moves the rod in and out of the arc groove through the gap between two adjacent arc grooves.

[0046] In this embodiment, the number of first magnetic attractors 12 is twice the number of second magnetic attractors 21. The first magnetic attractors 12 are distributed at the relative positions between each arc groove and between two adjacent arc grooves, and the second magnetic attractors 21 are located at the relative positions of the protrusions 11.

[0047] In this embodiment, the number of first magnetic suction components 12 is twice the number of second magnetic suction components 21. This not only solves the positioning problem of the first adapter 1 and the second snap-fit ​​component when they are docked, but also allows the second magnetic suction component 21 to be attracted to another first magnetic suction component 12 after they are rotated and snapped together. This provides a second layer of fixed attraction after the snap-fit, reducing the shaking of the bag when riding the motorcycle and improving the connection stability.

[0048] In this embodiment, both the first magnetic attractor 12 and the second magnetic attractor 21 are strong magnets.

[0049] The working principle of this embodiment is as follows: In use, the first adapter 1 is fixed to the fuel tank cap, and one side of the second adapter 2 is fixedly connected to the fuel tank bag body 100. Quick installation and disassembly are achieved through two sets of connection methods: First, when the first adapter 1 and the second adapter 2 are close together, the first magnetic 12 and the second magnetic 21 can quickly attract them together. This temporarily fixes the first adapter 1 and the second adapter 2. Furthermore, since the fuel tank bag body 100 obstructs the installation view, the attraction of the first magnetic 12 and the second magnetic 21 also allows the first adapter 1 and the second adapter 2 to quickly align, thus facilitating installation. The first adapter 1 and the second adapter 2 are positioned quickly without repeated observation of alignment, facilitating the subsequent rotation and engagement. Once aligned, rotating the second adapter 2 causes the slot 20 on it to rotate relative to the first adapter 1. The protrusion 11 on the first adapter 1 engages with the slot 20 during rotation, thus securing the first adapter 1 and the second adapter 2 and ensuring the motorcycle fuel tank bag does not fall off during driving. When leaving, rotating the second adapter 2 again disengages the slot 20 and protrusion 11, enabling quick disassembly and easy removal of the fuel tank bag. This embodiment features a simple structure, convenient and effective installation and disassembly, and improved ease of use.

[0050] Example 2

[0051] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0052] like Figure 1 As shown, a fuel tank adapter assembly also includes a pad 3, which is located between the first adapter 1 and the motorcycle fuel tank cap. The pad 3 has a mounting hole for threaded connection with the screw hole of the motorcycle fuel tank cap.

[0053] Since the fuel tank cap is not a regular flat surface and has a certain protrusion, directly fixing the first connector would result in the attachment surface being suspended, leading to uneven stress and deformation. Filling the spacer 3 between the motorcycle fuel tank cap and the first adapter 1 can eliminate the height difference between the two flat surfaces. This makes it less likely to deform when the threaded fixing is performed, enhancing the stability of the connection between the first connector and the motorcycle fuel tank cap. At the same time, the installation effect is flatter and more aesthetically pleasing, forming a better support effect and improving stability.

[0054] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0056] This embodiment describes a quick-release motorcycle fuel tank pack, such as... Figure 1 As shown, it includes a package body 100 and a fuel tank adapter assembly as described in the above embodiment, with the package body 100 fixed on the second adapter 2.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
