Description

Technical Field

[0001] The utility model relates to the technical field of vehicle loading accessories, and more specifically, to a quick-release connection structure and a motorcycle fuel tank bag adapter assembly. Background Art

[0002] Two-wheeled vehicles like motorcycles, bicycles, and electric scooters lack dedicated storage space, making them unable to carry some luggage. Many riders now equip their motorcycles with trunks and side boxes, which does solve some of the luggage carrying issues, but it also adds weight and width. Adding side boxes makes the motorcycle wider, which can occasionally make it less convenient, and the trunk raises the center of gravity, creating instability at high speeds. A motorcycle tank bag is a luggage bag mounted above the motorcycle's fuel tank. This is an ideal location for luggage, right under the rider's eye and directly in front of their chest when riding. It's compact and practical. How to quickly assemble and disassemble the tank bag is key to improving the ease of use of the fuel tank and luggage bag. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art motorcycles that are inconvenient for carrying objects or that carrying objects causes inconvenience to riding, and to provide a quick-release connection structure and a motorcycle tank bag adapter assembly, which can realize the rapid disassembly and assembly of the tank bag and the tank cover, greatly improving the convenience of carrying objects on the motorcycle.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A quick-release connection structure is provided, including a first mounting member, a locking assembly, and a second mounting member. The first mounting member is provided with a accommodating cavity. The locking assembly includes a connector and a driving member connected to each other. The connector and the driving member are both installed in the accommodating cavity. The connector is slidably connected to the first mounting member. The driving member can drive the connector to slide along the first mounting member. The second mounting member is detachably installed in the accommodating cavity. The connector is provided with a first plug-in portion. The second mounting member is provided with a second plug-in portion on the side. The first plug-in portion can be plugged and locked with the second plug-in portion. The driving member is partially exposed from the first mounting member.

[0006] The utility model connects the first mounting part to the bag body, the second mounting part to the fuel tank cover, and uses a locking assembly to lock the first mounting part and the second mounting part. Specifically, the driving part controls the plug-in part to slide relative to the first mounting part, thereby changing the plug-in relationship between the plug-in part and the second mounting part, and then realizing the locking or unlocking operation of the second mounting part; here, the relative sliding of the plug-in part can be realized by manual driving, and can also be realized by switch-controlled electric driving. Only a simple operation is needed to realize the disassembly and installation of the first mounting part and the second mounting part, thereby facilitating the connection and separation of the bag body and the fuel tank cover, which is very convenient and quick, and greatly improves the convenience of motorcycle loading.

[0007] Furthermore, the second mounting member is provided with a relief portion, and the plug-in member is located in a gap formed by the relief portion and the first mounting member. The relief portion is a groove, and space is vacated by the relief portion. The locking assembly is installed below the second mounting member and located at the relief portion to facilitate the installation of the second mounting member with the first mounting member. The position of the plug-in member is changed by the driving member so that when the plug-in member is plugged into the side portion of the second mounting member, the plug-in member is partially embedded in the second mounting member, thereby forming a blockage for the second mounting member and preventing the second mounting member from being separated from the first mounting member, which is a locked state. When the driving member drives the plug-in member to slide relative to the first mounting member and leave the second mounting member, the second mounting member can be separated from the first mounting member, which is an unlocked state.

[0008] Furthermore, the driving member includes a cable and a spring. One end of the spring is connected to the first mounting member, and the other end is connected to one end of the connector. The cable is connected to the other end of the connector, and the cable is partially exposed from the first mounting member. Pulling the cable manually causes the connector to slide in one direction, and the restoring force generated by the tensioned spring automatically causes the connector to slide back in the other direction. By placing the spring in its original position, the connector is locked, maintaining the locked state and preventing it from loosening.

[0009] Furthermore, the first mounting member is provided with a third plug-in portion on a side wall of the accommodating cavity, and the plug-in portion is provided with a fourth plug-in portion, wherein the third plug-in portion plugs into the fourth plug-in portion. By plugging the plug-in portion into the first mounting member and the side portion of the second mounting member simultaneously, the reliability of the plug-in portion locking the second mounting member can be improved.

[0010] Furthermore, the first mounting member is provided with a first limiting portion for limiting the sliding position of the plug-in member. The plug-in member is arranged across the first limiting portion, and the first limiting portion and the first plug-in member are arranged opposite each other. One end of the spring is mounted on the fourth plug-in member, and the other end is mounted on the first limiting portion. The gap between the first limiting portion and the third plug-in member forms a sliding space for the plug-in member. The first limiting portion and the third plug-in member can be used to limit the sliding distance of the plug-in member, thereby preventing the spring from being subjected to excessive force while being able to lock and unlock the second mounting member, thereby increasing the service life of the spring, and minimizing the travel of the plug-in member, thereby improving the efficiency of installation and removal of the second mounting member and the first mounting member.

[0011] Furthermore, a cable passage is provided within the accommodating cavity, through which the cable passes and protrudes beyond the first mounting member. The cable passage provides protection for the cable. Preferably, the cable passage extends from the first limiting portion to the other end of the accommodating cavity along the sliding direction of the connector and penetrates the first mounting member, allowing the cable to pass through the cable passage and be exposed outside the first mounting member, thereby preventing the cable from becoming entangled during installation of the second mounting member and the first mounting member.

[0012] Furthermore, a first guide portion is provided in the accommodating cavity, and a second guide portion is provided on the connector, and the second guide portion is plugged into the first guide portion. The first guide portion cooperates with the second guide portion to guide and limit the relative sliding of the connector and the first mounting member, thereby facilitating the connector to slide in a certain direction.

[0013] Furthermore, the first mounting member is provided with a third guide portion within the accommodating cavity, and the second mounting member is provided with a fourth guide portion, the third guide portion being plugged into the fourth guide portion. The third guide portion and the fourth guide portion cooperate to guide the second mounting member during assembly with the first mounting member, facilitating assembly of the second mounting member to a designated position, thereby facilitating locking and unlocking of the second mounting member by the plug-in member.

[0014] Furthermore, a fifth plug-in portion is provided in the accommodating cavity and beside the first guide portion, and a sixth plug-in portion is provided at the position of the second mounting member corresponding to the fifth plug-in portion. When the first plug-in portion can be plugged and locked with the second plug-in portion, the fifth plug-in portion can be plugged with the sixth plug-in portion; and / or a seventh plug-in portion is provided on the connector, and an eighth plug-in portion is provided at the position of the second mounting member corresponding to the seventh plug-in portion. When the first plug-in portion can be plugged and locked with the second plug-in portion, the seventh plug-in portion can be plugged with the eighth plug-in portion. Under the guidance of the third and fourth guide portions, the second mounting member is plugged and matched with the first mounting member, and at this time, the fifth plug-in portion is plugged with the sixth plug-in portion. When the first and second guide portions are guided and matched, the first plug-in portion can be plugged and locked with the second plug-in portion, and at the same time, the seventh plug-in portion is also plugged with the eighth plug-in portion.

[0015] Furthermore, it also includes a locking assembly, which is slidably connected to the first mounting member and can slide into the gap between the first limiting portion and the third plug-in portion. The locking assembly has a double locking effect. When the locking assembly slides into the gap between the first limiting portion and the third plug-in portion, it hinders the sliding of the plug-in member, and the plug-in member cannot slide relative to the first mounting member. Therefore, this is the locked state after the second mounting member and the plug-in member are plugged in, preventing the position of the plug-in member from moving, thereby ensuring a reliable connection between the second mounting member and the first mounting member; only when the locking assembly is slid out of the gap between the first limiting portion and the third plug-in portion can the plug-in member have sliding space, so that it can slide to a position that is separated from the second mounting member, so that the second mounting member can be separated from the first mounting member.

[0016] The utility model also provides a motorcycle tank bag adapter assembly, including the quick-release connection structure as described above, and also including a first pad for detachably connecting to the motorcycle tank cover, the first pad clamping the second mounting member between the first pad and the motorcycle tank cover, and the first pad is also provided with a fixing hole for threaded connection with the screw hole of the motorcycle tank cover. The second mounting member is connected to the tank cover through the first pad to facilitate the installation of the tank cover and the bag body. Since the connection plane at the tank cover is very irregular, the threaded connection is very prone to cracking and other problems. The first pad is provided to be screwed to the tank cover, and the connection force point is the fixing hole of the first pad. In this way, the second mounting member does not need to be directly connected to the motorcycle tank cover, and the second mounting member does not need to be drilled or screwed to the tank cover. It is not easy to be damaged or cracked, and has a better service life. When the first pad is cracked or damaged, the first pad can be replaced, which reduces maintenance costs.

[0017] Furthermore, the first backing plate is provided with a second stopper for limiting the rotation and displacement of the second mounting member, and the second mounting member is provided with a third stopper corresponding to the position of the second stopper. The second stopper and the third stopper are engaged for positional restraint. The engagement of the second and third stoppers prevents relative rotation and positional displacement between the second mounting plate and the first backing plate, thereby increasing the reliability of the second mounting member when attached to the fuel tank cap via the first backing plate.

[0018] Furthermore, the second mounting member is an annular chuck, the inner ring of which is provided with an eave. The first pad is positioned above the eave and is threadedly connected to the motorcycle's fuel tank cap. The second limiting portions are evenly distributed around the circumference of the first pad, and the third limiting portion is arranged on the eave. The annular chuck structure is hollowed out in the middle, reducing the overall weight. The first pad can be configured according to the specific shape and structure of the second mounting member, and the center of the first pad is also hollowed out, forming a clearing hole in the fuel tank cap. When refueling is needed, the fuel tank cap can be exposed in the internal clearing hole without removing the second mounting member, facilitating motorcycle refueling operations.

[0019] Furthermore, the invention also includes a pad disposed between the second mounting member and the motorcycle fuel tank cap, the pad having an alignment hole corresponding to the position of the fixing hole, and the thickness of the pad being consistent with the thickness of the eaves. Since the first pad is located above the eaves of the second mounting member, and the width of the first pad is greater than the width of the eaves of the second mounting member, an overhead layer is formed between the first pad and the eaves of the second mounting member. Directly reinforcing with threads will cause the first pad to deform due to uneven stress during the overhead layer. Therefore, the pad is added to the overhead layer between the eaves of the second mounting member and the first pad, filling the height difference between the first pad and the plane where the mounting screw holes of the motorcycle fuel tank cap are located. In this way, deformation of the first pad will not occur when threaded fixing is performed, thereby enhancing the stability of the connection between the second mounting member and the motorcycle fuel tank cap. At the same time, the installation effect is smoother and more beautiful, forming a better support effect and improving stability.

[0020] Furthermore, the device further includes a second backing plate for removably connecting to the tank bag, and the second backing plate is removably connected to the first mounting member. The first mounting member can be designed as an open structure, and the second backing plate acts as a bottom cover for the first mounting member. The second backing plate can be connected to the first mounting member first to shield the back of the first mounting member, preventing the driver and locking assembly from falling during assembly with the bag body. This facilitates the overall installation of the quick-release connection structure. Of course, omitting the second backing plate is also possible, and those skilled in the art can configure it accordingly based on user needs.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The locking assembly can be used to quickly install and disassemble the first mounting member and the second mounting member, so as to facilitate the quick disassembly and assembly of the bag body and the fuel tank cover. The whole process is easy to operate, very convenient and fast, which greatly improves the convenience of motorcycle loading. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Example 1

[0044] like Figures 1 to 14The figure shows a first embodiment of a quick-release connection structure of the present invention, including a first mounting member 1, a locking assembly 2, and a second mounting member 3. The first mounting member 1 is provided with a accommodating cavity 11. The locking assembly 2 includes a connector 21 and a driving member 22 that are connected to each other. The connector 21 and the driving member 22 are both installed in the accommodating cavity 11. The connector 21 is slidably connected to the first mounting member 1. The driving member 22 can drive the connector 21 to slide along the first mounting member 1. The second mounting member 3 is detachably installed in the accommodating cavity 11. The connector 21 is provided with a first plug-in portion 211. The second mounting member 3 is provided with a second plug-in portion 31 on the side. The first plug-in portion 211 can be plugged and locked with the second plug-in portion 31. The driving member 22 is partially exposed from the first mounting member 1.

[0045] In this embodiment, Figures 9 to 12 As shown, the first mounting member 1 and the second mounting member 3 are both in a circular ring structure, and the inner side of the ring extends inward to facilitate the installation of the second mounting member 3 and the locking assembly 2. The accommodating cavity 11 is the inner cavity of the ring; Figure 13 and Figure 14 As shown, the connector 21 is an arc-like structure as a whole; the drive member 22 drives the connector 21 to slide and insert it into the side of the second mounting member 3 so that the second mounting member 3 is partially pressed between the connector 21 and the first mounting member 1. Therefore, the second mounting member 3 cannot be separated from the first mounting member 1. At this time, the package body and the fuel tank cap can be installed; the drive member 22 drives the connector 21 to slide and separate it from the side of the second mounting member 3, so that the package body and the fuel tank cap can be separated. The arc-shaped connector 21 can slide back and forth in the direction toward the center of the circular first mounting member 1 and away from the center of the circle. The second connector 31 is a slot arranged along the side wall of the ring, and the first connector 211 is a protrusion arranged along the arc. The first connector 211 is inserted into the second connector 31 for locking and fixing. Preferably, a protrusion is provided at the top of the connector 21 and a groove is provided at the bottom of the second mounting member 3. When the first connector 211 and the second connector 31 are plugged in, the protrusion and the groove are used simultaneously for plugging in, thereby further improving the connection reliability between the connector 21 and the second mounting member 3.

[0046] As one embodiment of the present invention, the second mounting member 3 is provided with an escape portion 32, and the plug-in member 21 is located in the gap formed by the escape portion 32 and the first mounting member 1. The escape portion 32 is a relief groove provided on the side of the second mounting member 3 close to the first mounting member 1, so that the remaining position of the second mounting member 3 except for the escape portion 32 can form a good abutment or plug-in connection with the first mounting member 1. The plug-in member 21 is mostly located in the escape portion 32. The second plug-in portion 31 is a slot, and the second plug-in portion 31 is connected to the escape portion 32. The first plug-in portion 211 is a protrusion. When the driving member 22 drives the plug-in member 21 to insert the first plug-in portion 211 into the second plug-in portion 31, the state enters the locked state; when the driving member drives the plug-in member 21 to cause the first plug-in portion 211 to leave the second plug-in portion 31, the state enters the unlocked state.

[0047] As one embodiment of the present invention, the driving member 22 includes a cable 221 and a spring 222. One end of the spring 222 is connected to the first mounting member 1, and the other end is connected to one end of the connector 21. The cable 221 is connected to the other end of the connector 21, and the cable 221 is partially exposed from the first mounting member 1. A through hole is provided at the end of the first mounting member 1 away from the connector 21, and the cable 221 protrudes through the through hole. Applying force to the cable 221 causes the connector 21 to move toward the center of the first mounting member 1, thereby moving the connector 21 away from the second mounting member 3, which is the unlocking direction. The spring 222 is stretched and generates a restoring force that drives the connector 21 away from the center of the circle, thereby resetting the connector 21 and locking the connector 21. Moreover, when the spring 222 is in its original state, the first plug-in portion 211 is plugged into the second plug-in portion 31, and the connector 21 limits the plug-in of the second mounting member 3, which is in a locked state. Therefore, external force is required to pull and stretch it to achieve unlocking. Therefore, generally, when the cable 221 is not subjected to tension, the locking state of the connector 21 and the second mounting member 3 can be maintained, and the spring 222 has the function of preventing the lock from loosening.

[0048] As one embodiment of the present invention, the first mounting member 1 is provided with a third plug-in portion 12 on the side wall of the accommodating cavity 11, and the plug-in member 21 is provided with a fourth plug-in portion 212. The third plug-in portion 12 is plugged into the fourth plug-in portion 212. The third plug-in portion 12 is a groove, and the fourth plug-in portion 212 is a protrusion. Through the engagement of the protrusion and the groove, the first plug-in portion 211 is plugged into the second plug-in portion 31, and the third plug-in portion 12 is also plugged into the fourth plug-in portion 212, thereby improving the firmness and reliability of the connection between the second mounting member 3 and the first mounting member 1.

[0049] As an embodiment of the present utility model, the first mounting member 1 is provided with a first limiting portion 13 for slidingly limiting the plug-in member 21. The plug-in member 21 is arranged across the first limiting portion 13. The first limiting portion 13 and the first plug-in member 211 are arranged opposite to each other. One end of the spring 222 is installed on the fourth plug-in member 212, and the other end is installed on the first limiting portion 13. The gap between the first limiting portion 13 and the third plug-in member 12 forms a sliding space for the plug-in member 21. The first limiting portion 13 is a baffle arranged relative to the first plug-in portion 211. The first plug-in portion 211 is a groove. The sliding space of the plug-in component 21 is between the bottom of the groove and the first limiting portion 13. The first limiting portion 13 and the third plug-in portion 12 can limit the sliding distance of the plug-in component 21, thereby preventing the spring 222 from being subjected to excessive force while being able to lock and unlock the second mounting component 3 by the plug-in component 21, thereby improving the service life of the spring 222, and shortening the stroke of the plug-in component 21 as much as possible, thereby improving the efficiency of installation and disassembly of the second mounting component 3 and the first mounting component 1.

[0050] As one embodiment of the present invention, a cable passage 14 is provided within the accommodating chamber 11, through which the cable 221 passes and protrudes from the first mounting member 1. The cable passage 14 provides protection for the cable 221. Preferably, the cable passage 14 extends from the first limiting portion 13 to the other end of the accommodating chamber along the sliding direction of the connector 21 and penetrates the first mounting member 1. This allows the cable 221 to pass through the cable passage 14 and be exposed outside the first mounting member 1, thereby preventing the cable 221 from becoming entangled during installation of the second mounting member 3 and the first mounting member 1.

[0051] As one embodiment of the present invention, a first guide portion 15 is provided within the accommodating cavity 11, and a second guide portion 213 is provided on the connector 21, which is plugged into the first guide portion 15. Preferably, the first guide portion 15 is two symmetrically arranged ribs, each of which has a slot on its inner side. The second guide portion 213 is provided on both outer sides of the end of the connector 21 and is a plug-in strip that matches the slot. The plug-in strip and the slot facilitate the plug-in connection between the third connector 12 and the fourth connector 212, and also facilitates the smooth plug-in connection between the first connector 211 and the second connector 31.

[0052] As one embodiment of the present invention, the first mounting member 1 is provided with a third guide portion 16 within the accommodating cavity 11, and the second mounting member 3 is provided with a fourth guide portion 33. The third guide portion 16 is plugged into the fourth guide portion 33. The third guide portion 16 is located on the opposite side of the first guide portion 15. The third guide portion 16 is a slot, and the fourth guide portion 33 is an insert. The insert and the slot provide guidance when the second mounting member 3 is plugged into or abutted against the first mounting member 1, facilitating assembly of the second mounting member 3 to a desired position, thereby facilitating locking and unlocking of the second mounting member 3 by the connector 21. The third guide portion 16 is arranged opposite to the first plug-in portion 211; preferably, a limiting step 17 is provided at the third guide portion 16 of the first mounting member 1, and the third guide portion 16 is a slot opened from the limiting step 17; the setting of the limiting step 17 makes the first mounting member 1 a non-standard circular ring shape, and the limiting step 17 can play a role in preventing misinstallation, so that the second mounting member 3 and the first mounting member 1 have directionality when plugged in or abutted, and can only be installed along a specific direction.

[0053] As one embodiment of the present invention, a fifth plug-in portion 18 is provided within the accommodating cavity 11 and beside the first guide portion 15. A sixth plug-in portion 36 is provided on the second mounting member 3 corresponding to the fifth plug-in portion 18. When the first plug-in portion 211 is plugged and locked with the second plug-in portion 31, the fifth plug-in portion 18 can be plugged with the sixth plug-in portion 36. Preferably, the fifth plug-in portion 18 is a groove, and there are two of them. The fifth plug-in portion 18 is located outside the first guide portion 15, and the sixth plug-in portion 36 is a protrusion. Under the guidance of the third guide portion 16 and the fourth guide portion 33, the second mounting member 3 is plugged and matched with the first mounting member 1, at which time the fifth plug-in portion 18 is plugged with the sixth plug-in portion 36.

[0054] As one embodiment of the present utility model, the plug connector 21 is provided with a seventh plug portion 214, and the second mounting member 3 is provided with an eighth plug portion 37 at a position corresponding to the seventh plug portion 214. When the first plug portion 211 can be plugged and locked with the second plug portion 31, the seventh plug portion 214 can be plugged with the eighth plug portion 37. Preferably, the seventh plug portion 214 is a protrusion and is located on the side of the plug connector 21 opposite to the second mounting member 3. The eighth plug portion 37 is a groove. When the first guide portion 15 is guided and matched with the second guide portion 213, the first plug portion 211 can be plugged and locked with the second plug portion 31, and at the same time, the seventh plug portion 214 is also plugged with the eighth plug portion 37.

[0055] Example 2

[0056] The following is a second embodiment of a quick-release connection structure of the present invention. This embodiment is similar to embodiment 1, except that it further includes a locking assembly 4, which is slidably connected to the first mounting member 1. The locking assembly 4 can slide into the gap between the first limiting portion 13 and the third plug-in portion 12.

[0057] The locking assembly 4 has a double locking effect. When the locking assembly 4 slides into the gap between the first limiting portion 13 and the third plug-in portion 12, it hinders the sliding of the plug-in component 21, and the plug-in component 21 cannot slide relative to the first mounting component 1. Therefore, this is the locked state after the second mounting component 3 and the plug-in component 21 are plugged in, which prevents the position of the plug-in component 21 from moving, thereby ensuring a reliable connection between the second mounting component 3 and the first mounting component 1; only when the locking assembly 4 is slid out of the gap between the first limiting portion 13 and the third plug-in portion 12, can the plug-in component 21 have sliding space, so that it can slide to a position that is separated from the second mounting component 3, so that the second mounting component 3 can be separated from the first mounting component 1.

[0058] In this embodiment, Figure 7 and Figure 8 As shown, the locking assembly 4 includes a limit member 42 and a sliding member 41. The sliding member 41 is an arc-shaped structure. The sliding member 41 is provided with an arc-shaped inner cavity. The limit member 42 is arranged in the inner cavity of the sliding member 41 and partially covers the outer portion of the sliding member 41. There are two limit members 42, and the two limit members 42 are also arranged along the arc to limit the extreme positions of the two ends of the sliding member 41 respectively, so that the stroke of the sliding member 41 is determined. When the sliding member 41 slides to the inner cavity and abuts against one of the limit members 42, the sliding member 41 is located between the first limit portion 13 and the third plug-in portion 12, it is a double locking state at this time, the connector 21 cannot be separated from the second mounting member 3, so the second mounting member 3 cannot be separated from the first mounting member 1; when the sliding member 41 slides to the inner cavity and abuts against another limiting member 42, the sliding member 41 withdraws from the gap between the first limiting portion 13 and the third connector 12, and it is a single-layer unlocking state at this time. In this state, the connector 21 is driven by the driving member 22 to slide until the first connector 211 and the second connector 31 are separated, so that the first mounting member 1 and the second mounting member 3 can be separated.

[0059] Example 3

[0060] like Figure 15 The figure shows an embodiment of a motorcycle fuel tank bag adapter assembly of the present invention, which includes the quick-release connection structure as described above, and also includes a first pad 5 for detachably connecting to the motorcycle fuel tank cover. The first pad 5 fixes the second mounting member 3 between the first pad 5 and the motorcycle fuel tank cover. The first pad 5 is also provided with a fixing hole 51 for threaded connection with the screw hole of the motorcycle fuel tank cover. Figure 16 shown.

[0061] The second mounting member 3 is connected to the fuel tank cap via the first backing plate 5, facilitating installation of the fuel tank cap and the housing. Because the connection plane of the fuel tank cap is highly irregular and the threaded connection is prone to cracking, the first backing plate 5 is threadedly connected to the fuel tank cap, with the force bearing point being the backing plate's fixing hole 51. This eliminates the need for the second mounting member 3 to be directly connected to the motorcycle's fuel tank cap. The second mounting member 3 does not require drilling or threading with the fuel tank cap, making it less susceptible to damage and cracks and extending its service life. If the first backing plate 5 develops cracks or other damage, it can simply be replaced, reducing maintenance costs.

[0062] As one embodiment of the present invention, the first backing plate 5 is provided with a second stopper 52 for limiting the rotation and displacement of the second mounting member 3. The second mounting member 3 is provided with a third stopper 34 corresponding to the position of the second stopper 52. The second stopper 52 and the third stopper 34 are engaged and restrained. The engagement of the second stopper 52 and the third stopper 34 prevents relative rotation and positional displacement between the second mounting plate and the first backing plate 5, thereby enhancing the reliability of the second mounting member 3 when mounted to the fuel tank cap via the first backing plate 5.

[0063] In one embodiment of the present invention, the second mounting member 3 is an annular chuck. The inner ring of the second mounting member 3 is provided with an eave 35. The first backing plate 5 is positioned above the eave 35 and is threadedly connected to the motorcycle's fuel tank cap. Second limiting portions 52 are evenly distributed around the circumference of the first backing plate 5, and third limiting portions 34 are arranged on the eave 35. The annular chuck structure, with a hollow center, reduces overall weight. The first backing plate 5 can be configured according to the specific shape and structure of the second mounting member 3. The center of the first backing plate 5 is also hollowed out, forming a clearing hole in the fuel tank cap. When refueling is needed, the fuel tank cap can be exposed in the internal clearing hole without removing the second mounting member 3, facilitating motorcycle refueling operations.

[0064] As an embodiment of the present invention, a spacer 6 is further included, which is arranged between the second mounting member 3 and the motorcycle fuel tank cap. The spacer 6 is provided with an alignment hole corresponding to the position of the fixing hole 51, and the thickness of the spacer 6 is consistent with the thickness of the eave 35. Since the first pad 5 is located above the eave 35 of the second mounting member 3 and the width of the first pad 5 is greater than the width of the eave 35 of the second mounting member 3, an overhead layer is formed between the first pad 5 and the eave 35 of the second mounting member 3. Directly reinforcing with threads would cause the first pad 5 to deform due to uneven stress during the overhead layer. Therefore, the spacer 6 is added to the overhead layer between the eave 35 of the second mounting member 3 and the first pad 5 to fill the height difference between the first pad 5 and the plane where the mounting screw holes of the motorcycle fuel tank cap are located. In this way, deformation of the first pad 5 will not occur during threaded fixing, thereby enhancing the stability of the connection between the second mounting member 3 and the motorcycle fuel tank cap. At the same time, the installation effect is smoother and more beautiful, forming a better support effect and improving stability.

[0065] One embodiment of the present invention further includes a second backing plate 7 for detachably connecting to the fuel tank bag. The second backing plate 7 is detachably connected to the first mounting member 1. The first mounting member 1 can be designed as an open structure, and the second backing plate 7 acts as a bottom cover for the first mounting member 1. The second backing plate 7 can be connected to the first mounting member 1 first to shield the back of the first mounting member 1 and prevent the driver 22 and locking assembly 4 from falling during assembly with the bag body. This facilitates the overall installation of the quick-release connection structure. Of course, omitting the second backing plate 7 is also possible, and those skilled in the art can configure it accordingly based on user needs.

[0066] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
