[0024] 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.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a motorcycle single swingarm flat fork structure, including a flat fork body 1, a first connector 2 fixed at one end of the flat fork body 1, and a connector 3 fixed at the top of one end of the flat fork body 1.

[0027] The side wall of the connecting seat 3 is rotatably connected to the connecting shaft 4 through the bearing seat, and the side wall of the connecting shaft 4 is provided with a cross groove 5. The connecting shaft 4 and the connecting seat 3 are rotatably connected through the bearing seat. One end of the cross groove 5 is connected to the positioning hole 6. The outer side wall of the connecting shaft 4 is provided with a slot 7. A snap-fit ​​seat 8 is distributed on one side of the connecting seat 3, and a return spring 9 is fixedly connected to the inner cavity of the snap-fit ​​seat 8. The other end of the return spring 9 is connected to the movable seat 10. A cross block 11 is fixedly provided at the end of the movable seat 10 away from the return spring 9, and a positioning rod 12 is fixedly provided on the other side of the cross block 11. A lever ring 13 is sleeved on the outer ring surface of the snap-fit ​​seat 8. The lever ring 13 is connected to the movable seat 10 through a rod, and a sliding groove for the rod to slide is provided on the outer ring surface of the snap-fit ​​seat 8.

[0028] In use, first, the dial ring 13 is turned laterally. This causes the movable seat 10, which is fixedly connected to its inner side, to move laterally as well. The lateral movement of the movable seat 10 compresses the return spring 9 fixedly connected to one side, causing deformation of multiple return springs 9. The deformation of the return springs 9 generates a reverse force. Simultaneously, the lateral movement of the movable seat 10 causes the cross block 11 and the positioning rod 12 to retract laterally. Then, under the action of the movable seat 10, the cross block 11 retracts to the inner side of the locking seat 8. When both cross blocks 11 have retracted to the inner side of the locking seat 8, they push the locking seat 8 laterally. At this time, the locking seat 8 causes the positioning rod 12 to move along the side wall of the connecting shaft 4, while the positioning rod 12 slides inside the slot 7, thus connecting the locking seat 8 to the connecting shaft 4. The purpose of providing guidance is to prevent positional deviation during the connection between the two. At the same time, the lateral force applied to the dial ring 13 is released, and the reverse force generated by the deformation of the return spring 9 will push the movable seat 10 in the opposite direction, thereby causing the movable seat 10 to drive the cross block 11 to perform lateral reset. Then the cross block 11 slides along the side wall of the connecting shaft 4. When the snap-fit ​​seat 8 slides to the appropriate position, the cross block 11 will move to one side of the cross groove 5. Subsequently, under the action of the return spring 9, the cross block 11 is input into the cross groove 5, and the positioning rod 12 is input into the inner side of the positioning hole 6 under the action of the cross block 11. This can improve the stability of the connection between the snap-fit ​​seat 8 and the connecting seat 3, realize the quick connection of the shock absorber 15, and facilitate subsequent disassembly, resulting in greater overall flexibility.

[0029] like Figure 1 and Figure 2 As shown, in some embodiments, a connecting ear 14 is fixedly provided in the middle of the outer ring surface of the card seat 8, and a shock absorber 15 is connected to the other end of the connecting ear 14. A second connector 16 is connected to the end of the shock absorber 15 away from the connecting ear 14.

[0030] In use, the shock absorber 15 can be connected to the vehicle body through the second connector 16 at one end. When the shock absorber 15 is compressed, it will deform, thereby achieving the purpose of shock absorption. The shock absorber 15 is rotatably connected to the locking seat 8 through the connecting ear 14, which makes it convenient to adjust the angle of the shock absorber 15 during installation, so as to better achieve the purpose of shock absorption.

[0031] like Figure 4 As shown, in some embodiments, the cross groove 5 and the connecting shaft 4 form an integrated structure, and the positioning hole 6 is connected to the center point of one end of the cross groove 5.

[0032] When in use, when the cross block 11 and the positioning rod 12 are respectively locked inside the cross groove 5 and the positioning hole 6, it is convenient to quickly connect the locking seat 8 and the connecting seat 3.

[0033] like Figure 3 As shown, in some embodiments, the return springs 9 are equidistantly distributed along the center point of the snap-fit ​​seat 8, and the two ends of the return springs 9 are respectively fixedly connected to the inner side wall of the snap-fit ​​seat 8 and one end of the movable seat 10.

[0034] When in use, when the return spring 9 is deformed by a lateral force, it will generate a reverse force, which will facilitate the subsequent use of the reverse force generated by the deformation of the return spring 9 to push the movable seat 10 in the opposite direction, thereby realizing the lateral movement of the movable seat 10.

[0035] like Figure 2 and Figure 3 As shown, in some embodiments, the outer diameter of the cross block 11 is adapted to the inner diameter of the cross groove 5, and the cross blocks 11 are symmetrically distributed along the vertical center line of the snap-fit ​​seat 8.

[0036] When in use, since the size of the cross block 11 is adapted to the size of the cross groove 5, the stability of the connection between the snap-fit ​​seat 8 and the connector 3 can be ensured when the cross block 11 is inserted into the inside of the cross groove 5.

[0037] like Figure 3 As shown, in some embodiments, the positioning rod 12 is fixed at the center point of one side of the cross block 11, and the outer diameter of the positioning rod 12 is adapted to the inner diameter of the positioning hole 6.

[0038] When in use, since the size of the positioning rod 12 is compatible with the size of the positioning hole 6, the positioning of the card seat 8 can be achieved when the cross block 11 moves laterally, causing the positioning rod 12 to move and one end of it to be inserted into the inside of the positioning hole 6.

[0039] In summary, when quick installation between the shock absorber 15 and the fork body 1 is required, the throttle ring 13 is moved laterally. The throttle ring 13 causes the movable seat 10 to laterally compress the return springs 9, resulting in deformation of multiple return springs 9. Simultaneously, the lateral movement of the movable seat 10 causes the cross block 11 and the positioning rod 12 to retract laterally. The cross block 11 retracts to the inside of the locking seat 8, then pushes the locking seat 8. At this time, the locking seat 8 causes the positioning rod 12 to move along the side wall of the connecting shaft 4, while the positioning rod 12 slides inside the slot 7, thus providing guidance for the connection between the locking seat 8 and the connecting shaft 4. Simultaneously, the applied pressure is released... A lateral force is applied to the dial ring 13, and then the return spring 9 pushes the movable seat 10 in the opposite direction, causing the movable seat 10 to drive the cross block 11 to return laterally. Then the cross block 11 slides along the side wall of the connecting shaft 4. When the snap-fit ​​seat 8 slides to the appropriate position, the cross block 11 will move to one side of the cross groove 5. Then, under the action of the return spring 9, the cross block 11 is input into the cross groove 5, and the positioning rod 12 is input into the inner side of the positioning hole 6 under the action of the cross block 11. This can improve the stability of the connection between the snap-fit ​​seat 8 and the connecting seat 3, realize the quick connection of the shock absorber 15, and facilitate subsequent disassembly, making the overall flexibility higher.
