[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Example 1:

[0044] Please see Figure 1-5 The present invention provides the following technical solution: a quick-release module, including a base 1 and a connecting part 2 for carrying items. Two first slots 11 are symmetrically provided on opposite side walls of the base 1. Buckles 22 are slidably installed on opposite side walls of the connecting part 2 via springs 21. The end of the buckle 22 away from the spring 21 is trapezoidal, arc-shaped or triangular. The connecting part 2 is connected to the base 1 from a direction perpendicular to the plane of the base 1. A baffle 13 and a disassembly port 14 are continuously provided on one side edge of the first slot 11 opposite to the connection direction of the connecting part 2. The length L1 of the baffle 13, the span D1 of the disassembly port 14, the thickness H of the buckle 22 and the width d of the buckle 22 are: L1>d>D1≥H.

[0045] As an optional implementation of this utility model, the buckle 22 is a very common prior art, and the combination of the buckle 22 and the spring 21 is also a common method. Specifically, in this technical solution, the buckle 22 relies on the elastic force of the spring 21 to extend and retract on the side wall of the connecting part 2.

[0046] During the process of connecting part 2 to base 1, buckle 22 retracts when it encounters the obstruction of baffle 13. After passing baffle 13, buckle 22 extends out by the rebound force of spring 21 and presses against the surface of the slot. Baffle 13 also blocks the extended end of buckle 22 so that it cannot return to the original path and dislodge from the slot.

[0047] During the process of removing the connecting part 2 from the base 1, the connecting part 2 can be pulled or pushed first, so that the buckle 22 slides in the slot. Since the width d of the buckle 22 is less than the length L1 of the baffle 13 and greater than the span D1 of the disassembly port 14, the buckle 22 cannot be pulled out directly in the opposite direction to the direction in which the connecting part 2 is connected to the base 1. However, the thickness H of the buckle 22 does not exceed the span D1 of the disassembly port 14, so the connecting part 2 can be rotated so that the buckle 22 can pass through the disassembly port 14 on the thick upper surface, thus making the connecting part 2 successfully removed from the base 1.

[0048] Therefore, the quick-release module constructed by this technical solution can be directly pressed into place during installation, and pulled / pushed and then lifted / pressed in the opposite direction of insertion during disassembly. The operation process is very fast and can be completed with one hand, which is very convenient. Furthermore, since two forces in different directions are required to complete the disassembly operation, it will not naturally detach after assembly. Therefore, compared with existing quick-release fixing methods such as magnetic attraction, buckles, or straps, the installation stability of this disassembly module is not bad. It is suitable for static or relatively static scenarios. In moving scenarios, since the connecting part 2 or the object needs to be subjected to force on one side for the buckle 22 to rotate in the first slot 11, this requires non-parallel forces. Therefore, it can also be applied in some moving scenarios, such as the subsequent quick-release base for motorcycle fuel tank bags.

[0049] In this technical solution, it is not limited whether the item is mounted on the base 1 or the item is mounted on the connecting part 2. As for the specific application scenario of this quick-release module, it can be on the fuel tank bag disassembly structure in the following embodiment, or in other scenarios that require disassembly and assembly functions, such as wall mounting, vehicle brackets, etc.

[0050] The base 1 can be a box-shaped structure or a U-shaped structure. The two first slots 11 can be located on the surfaces of the two side walls of the base 1 facing each other or on the surfaces of the two side walls of the base 1 opposite to each other. The limitation of the first slots 11 here should be regarded as being only on the two symmetrical side walls of the base 1, and they are either designed to face each other or to be designed to be opposite to each other.

[0051] For the connecting part 2 (which can also be the base 1), since the item is mounted, after the connecting part 2 is connected to the base 1, the buckle 22 and the item (or the connecting part 2 itself) clamp the baffle 13 between them. This ensures that after the connecting part 2 is connected to the base 1, it cannot directly detach from the base 1 along the path opposite to the connection direction, nor will it further detach from the base 1 along the connection direction. Of course, for those skilled in the art, the baffle 13 can also be designed on the side symmetrical to the first slot 11 and the baffle 13. The connecting part 2 can be two independent structures installed with the item to be mounted, or it can be a U-shaped structure installed with the item to be mounted. This technical solution does not make specific limitations on this.

[0052] The above structure provides a simple and quick disassembly method that can be operated with one hand, and the installation is highly stable with a wide range of applications.

[0053] like Figure 3 As shown, the side of the baffle 13 near the disassembly port 14 has a rounded corner, and the radius of the rounded corner R ≤ L1-d.

[0054] As an optional implementation of this utility model, as mentioned above, when the buckle 22 rotates with the rotation of the connecting part 2, the rounded corners make the rotation of the buckle 22 smoother, which makes the disassembly process of the connecting part 2 smoother. The design of the radius of the rounded corner and the width of the buckle 22 not exceeding the length of the baffle 13 in the first slot 11 also ensures that the buckle 22 will not disassemble naturally when subjected to other forces in the absence of the above-mentioned manual disassembly operation.

[0055] like Figure 1-2 As shown, two symmetrical first slots 11 and / or second slots 12 are disposed facing each other in the inner wall of the base 1, and two symmetrical buckles 22 are disposed oppositely in the outer wall of the connecting part 2.

[0056] As an optional implementation of this utility model, as mentioned above, in practice, the first slot 11 and the second slot 12 can both be designed on the two symmetrical inner sidewalls of the base 1, or on the outer sidewall, or one type of slot can be designed on the inner sidewall and the other on the outer sidewall. However, in order to reduce the overall volume of the quick-release module, it is preferable that they are both designed on the two symmetrical inner sidewalls of the base 1, so as to improve the adaptability of this quick-release module and reduce the cost of consumables.

[0057] Example 2:

[0058] Please see Figure 1-5 The present invention also provides the following technical solution: Compared with the quick-release module in embodiment 1, two second slots 12 are symmetrically provided on the opposite side walls of the base 1. The second slots 12 are located on the side of the first slot 11 away from the direction of the baffle 13 in the first slot 11. The relationship between the length L2 of the baffle 13 in the second slot 12, the span D2 of the disassembly port 14 and the width d of the buckle 22 is: D2≥L2>d.

[0059] As an optional implementation of this utility model, although Embodiment 1 can provide relatively reliable installation stability by relying solely on a set of symmetrically designed first slots 11 and a set of symmetrical buckles 22, there is a risk of loosening in dynamic environments, especially when facing more complex stress conditions. The essential difference between the second slot 12 and the first slot 11 is that the span D2 of the disassembly port 14 in the second slot 12 allows the buckles 22 to disengage directly without rotation, ensuring that the connecting part 2 can be disassembled as a whole without affecting the original disassembly process. During disassembly, the connecting part 2 first disengages from the second slot 12 and then rotates around the rounded corner of the baffle 13 in the first slot 11 to complete the disassembly operation. However, after the buckles 22 before and after the connecting part 2 are installed in the first slot 11 and the second slot 12 respectively, the baffles 13 in both slots provide resistance to the connecting part 2 in the direction perpendicular to the plane of the base 1, making it less likely for the connecting part 2 to rotate, improving the installation stability of the connecting part 2, and thus better coping with complex dynamic environments.

[0060] like Figure 2 As shown, the second slot 12 has a ramp 121 at the disassembly port 14 to prevent the buckle 22 from falling out freely.

[0061] As an optional implementation of this utility model, as described in Embodiment 1 regarding the buckle 22, the buckle 22 is telescopically connected to the connecting part 2 via a spring 21. Therefore, during disassembly, after the buckle 22 moves to the disassembly port 14, the user pulls the connecting part 2, and the buckle 22 retracts, thus smoothly completing the entire disassembly operation. Furthermore, the design of the ramp 121 ensures that even when the connecting part 2 moves to the point where the buckle 22 is located at the disassembly port 14, minor vibrations will not easily cause the buckle 22 to detach from the ramp 121 when the disassembly module is applied in a complex dynamic environment. Of course, this requires the superposition of forces from two different directions at the same time. While a complex dynamic environment increases the probability of this happening, it is not frequent. The design of the ramp 121 allows the disassembly module to more effectively handle such situations.

[0062] Furthermore, the planes containing the two symmetrical slots on the two side walls of the base 1 have an angle in the direction in which the connecting part 2 slides out of the base 1.

[0063] As an optional implementation of this utility model, as described in Embodiment 1 regarding the buckle 22, the buckle 22 is telescopically connected to the connecting part 2 via a spring 21. When two symmetrical slots in each group form an angle in the sliding direction, it means that when the buckle 22 moves to the position of its disassembly port 14, the length of the spring 21 needs to be shortened, which means it needs to overcome more pressure. Therefore, in complex dynamic environments, the sliding of the buckle 22 in each slot needs to overcome more resistance, and this resistance needs to be maintained continuously; otherwise, the rebound force of the spring 21 will cause the buckle 22 to return to the position blocked by the baffle 13. In other words, the angle design of the slots in this technical solution makes it more difficult for the buckle 22 to disassemble, greatly reducing the probability of the connecting part 2 disassembling naturally, and enabling this disassembly module to more reliably cope with complex dynamic scenarios.

[0064] like Figure 1 As shown, both the connecting part 2 and the base 1 are provided with magnets 3, and the magnets 3 on the connecting part 2 and the base 1 are aligned in the direction in which the connecting part 2 enters the base 1.

[0065] As an optional implementation of this utility model, the aligned magnets 3 enable the connecting part 2 and the base 1 to automatically align and attract each other as they approach each other. This makes it more difficult for the connecting part 2 to detach from the base 1 in dynamic environments, thereby improving the installation stability of this disassembly module and making it more reliable and feasible.

[0066] Example 3:

[0067] Compared to Embodiment 1, in this embodiment, two symmetrical first slots 11 and / or second slots 12 are disposed opposite to each other in the outer side wall of the base 1, and two symmetrical buckles 22 are disposed opposite to each other in the inner side wall of the connecting part 2.

[0068] As an optional implementation of this utility model, referring to Embodiment 1, the card slots in this technical solution are all designed on the two symmetrical outer side walls of the base 1, which can also be implemented in the same way.

[0069] Example 4:

[0070] Please see Figure 2 as well as Figure 6-7 The present invention also provides the following technical solution: a quick-release base for a fuel tank bag, including any of the quick-release modules in embodiments 1-3, and also including an adapter 4 for connecting the fuel tank and a fixing member 5 for connecting the fuel tank bag. The base 1 is fixedly connected to the adapter 4, the connecting part 2 is connected to the fixing member 5, and the connecting part 2 and the side wall of the base 1 that can contact each other are provided with mutually cooperating guide slopes 23.

[0071] As an optional embodiment of this utility model, the fuel tank bag needs to be installed on the fuel tank, so it is usually placed horizontally or nearly horizontally after installation. The adapter 4 is a widely used existing technology in the field of fuel tank bags, and it can be U-shaped. In this technical solution, the guide slope 23 makes the installation of the base 1 and the connecting part 2 more tight. This allows the buckle 22 to be blocked when subjected to lateral force in the horizontal direction after it is installed in each slot, thereby reducing the lateral vibration of the connecting part 2 in the base 1. This reduces the lateral vibration of the fuel tank bag when the motorcycle is running, and reduces the risk of damage to the items stored in the bag.

[0072] It is worth noting that when this embodiment is combined with Embodiment 2, the magnet 3 enables automatic alignment of the fuel tank pack during installation, making the installation process smoother and increasing the installation speed. Furthermore, regardless of which embodiment the guide slope 23 is combined with, it should not affect the sliding of the buckle 22 in each slot. Therefore, the inclination direction of the guide slope 23 should be perpendicular to the sliding direction of the buckle 22 (equivalent to the length direction of the baffle 13), and this technical solution does not specifically limit the specific inclination angle of the guide slope 23.

[0073] With the above structure, the fuel tank bag is more secure after installation, making it easier and faster to install and remove, and better able to resist vibrations encountered when riding a motorcycle, thus reducing the risk of damage to the item.

[0074] like Figure 6-7 As shown, the fastener 5 includes:

[0075] Adjustment plate 51 is used to connect the fuel tank bag. Adjustment plate 51 is provided with T-shaped groove 511, slot 512 and limiting groove 513 respectively.

[0076] The connecting plate 52 is fixedly connected to the connecting part 2. The side of the connecting plate 52 near the adjusting plate 51 is provided with an elastic block 521 that cooperates with the limiting groove 513. The connecting plate 52 is also rotatably mounted with a plug 522 that cooperates with the slot 512.

[0077] The sliding key 53 is located on the side of the adjusting plate 51 away from the connecting plate 52 and slides in cooperation with the T-shaped groove 511. The sliding key 53 is fixedly connected to the connecting plate 52.

[0078] Both slot 512 and limiting slot 513 are provided in multiples and are arranged in a linear array.

[0079] As an optional embodiment of this utility model, when it is necessary to adjust the installation position of the fuel tank pack on the fuel tank, rotate the insert block 522 to disengage it from the slot 512 on the adjusting plate 51. Since the sliding key 53 slides in the T-shaped groove 511, the fuel tank pack can be directly pushed or pulled. The elastic block 521, due to its own elasticity, can move into or out of the limiting groove 513 according to the force applied. After adjusting to the appropriate position, the insert block 522 can be reinserted into the slot 512. The elastic block 521 and the insert block 522 form a stable position limit for the adjusting plate 51, making the connection between the fuel tank pack and the connecting part 2 stable. The insert block 522 can be mounted on the connecting plate 52 by a torsion spring, so that it can automatically insert into the slot 512 when no force is applied, which is convenient for adjustment.

[0080] Example 5:

[0081] Please see Figure 8-9 The present invention also provides the following technical solution: a fuel tank bag, including the quick-release base mentioned above, and also including a bag body 6 and a bag bottom 7 connected to each other, with a handle 61 provided on the bag body 6 or the bag bottom 7.

[0082] As an optional implementation of this utility model, when installing the fuel tank bag, the connecting part 2 of the bottom 7 of the fuel tank bag is aligned with the base 1 installed on the adapter 4. Under the attraction of the magnet 3, the inclined guide cooperation between the base 1 and the connecting part 2 causes the buckle 22 to automatically snap into the slot, and the buckle 22 is clamped by the baffle 13 and the connecting part 2. When disassembling, the fuel tank bag is pulled / pushed by the handle 61, so that the buckle 22 moves to the disassembly port 14. Then, the handle 61 is lifted / pressed, so that the buckle 22 in the first slot 11 rotates, and then the buckle 22 is dislodged from the slot, completing the disassembly operation.

[0083] The working principle and usage process of this utility model are as follows: When the connecting part 2 is connected to the base 1, the buckle 22 is blocked by the baffle 13 and retracts. After passing the baffle 13, the buckle 22 extends out by the rebound force of the spring 21 and presses against the surface of the slot. The baffle 13 also blocks the extended end of the buckle 22 so that it cannot return along the original path and is dislodged from the slot.

[0084] During the process of removing the connecting part 2 from the base 1, the connecting part 2 can be pulled or pushed first, so that the buckle 22 slides in the slot. Since the width d of the buckle 22 is less than the length L1 of the baffle 13 and greater than the span D1 of the disassembly port 14, the buckle 22 cannot be pulled out directly in the opposite direction to the direction in which the connecting part 2 is connected to the base 1. However, the thickness H of the buckle 22 does not exceed the span D1 of the disassembly port 14, so the connecting part 2 can be rotated so that the buckle 22 can pass through the disassembly port 14 on the upper surface of the thickness, thus making the connecting part 2 successfully removed from the base 1.

[0085] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
