Description

Technical Field

[0001] This utility model relates to the field of motorcycle starter lever technology, and specifically to a connection structure for a motorcycle starter lever. Background Technology

[0002] The starter lever, as one of the key components of the motorcycle starting system, ensures that the motorcycle can start smoothly.

[0003] Chinese patent document CN212106098U discloses a connection structure for a motorcycle starter lever. By inserting the connecting chamber into the mounting chamber, eight limiting rods are respectively inserted into eight limiting grooves. Then, rotating the rotating chamber causes the threaded ring to rotate. The threaded ring moves forward through the threaded connection between the inner circumferential wall and the threaded groove, compressing the moving rod. This causes the metal chamber to move forward, further driving the compression ring to move forward. As a result, the three rotating rods are compressed by the compression ring, causing the three rotating rods to flip. The return spring is stretched, so that the three rotating rods pass through three second rectangular through holes and compress the inner circumferential wall of the mounting chamber, thus fixing the mounting chamber.

[0004] However, the above solution requires high precision in the connection between the connecting compartment and the installation compartment, and involves many connection structures, making the installation process more complicated. Furthermore, the return spring is prone to fatigue failure, resulting in insufficient overall structural stability and affecting the service life and reliability of the motorcycle starter lever.

[0028] Example 1

[0029] like Figure 1-4 As shown, the present invention proposes a connection structure for a motorcycle starter lever, including a drive shaft 1, a crank 2, a cap nut 9, a rotating seat, and a connector.

[0030] The connector is located at one end of the drive shaft 1, and a connecting block 7 is sleeved on the outside of the connector for rotating the connector and the drive shaft 1 in use.

[0031] The rotating seat is installed on the top of the connecting block 7 and connected to the crank 2;

[0032] The cap nut 9 is installed at the end of the connector and is located at one end of the connector block 7 and connected to the connector block 7.

[0033] In this embodiment, the connector is installed at the end of the drive shaft 1 and is integrally arranged with the drive shaft 1. The crank 2 is connected to the rotating seat and mounted on the connecting block 7. The connecting block 7 is sleeved on the outside of the connector and the end of the connector extends from the middle of the connecting block 7 to the end of the connecting block 7. At the same time, the cap nut 9 is connected to the connector at the end of the connecting block 7, so that the connecting block 7 is fixedly installed on the connector, ensuring the stability of the connection structure and improving the ease of installation of the starter rod.

[0034] Example 2

[0035] like Figure 3-4 As shown, the present invention proposes a connection structure for a motorcycle starter lever. Compared with embodiment one, the difference in this embodiment is that the connector includes a rectangular block 10 and a stud 11.

[0036] The rectangular block 10 is installed at one end of the drive shaft 1 and inserted into the middle of the other end of the connecting block 7;

[0037] The stud 11 is installed at one end of the rectangular block 10 and extends through the connecting block 7 to one end of the connecting block 7.

[0038] In an optional embodiment, a second rectangular groove 16 is provided at the middle of the other end of the connecting block 7. When the rectangular block 10 and the connecting block 7 are installed together, the rectangular block 10 is accommodated in the connecting block 7. This is used to tightly connect the connecting block 7 and the rectangular block 10 during use, so as to achieve uniform force transmission, reduce wear, and extend the service life of the component.

[0039] In this embodiment, the drive shaft 1 is connected to the connecting block 7 by a rectangular block 10. The shape of the rectangular block 10 matches the internal structure of the connecting block 7, ensuring that the connecting block 7 rotates synchronously with the rectangular block 10, thereby causing the rectangular block 10 to rotate synchronously with the drive shaft 1, which in turn starts the motorcycle. At the same time, by extending the stud 11 from one end of the rectangular block 10 to the other end of the connecting block 7 and connecting the stud 11 to the cap nut 9 at the other end of the connecting block 7, a tight connection between the rectangular block 10 and the connecting block 7 is ensured, improving the installation stability of the connecting block 7.

[0040] Example 3

[0041] like Figure 1-3 As shown, the present invention proposes a connecting structure for a motorcycle starter lever. Compared with the first embodiment, the difference in this embodiment is that the rotating seat includes a connecting column 3, a retaining spring 4, a washer 5, and a limiting block 6.

[0042] The limiting block 6 is installed at the top of the connecting block 7 and is movably connected to the bottom side of the crank 2, thereby limiting the rotation of the crank 2;

[0043] The connecting column 3 is installed at the top center of the limiting block 6 and inserted into one end of the crank 2, which is used to support and limit the crank 2 during use;

[0044] Washer 5 is fitted on the outside of connecting post 3 and connected to the crank 2;

[0045] The retaining ring 4 is installed at the top of the connecting post 3 and connected to the washer 5. It is used to limit the washer 5 above the crank 2 during use, so that the cooperation between the retaining ring 4 and the washer 5 limits the crank 2 to the connecting post 3.

[0046] In this embodiment, the bottom end of the crank 2 is sleeved on the outside of the connecting post 3, and the washer 5 is sleeved on the outside of the connecting post 3 above the crank 2. At the same time, the position of the washer 5 is limited by the connection between the retaining spring 4 and the connecting post 3, thereby installing the crank 2 on the connecting post 3. This ensures the stable support of the connecting post 3 and the crank 2. Meanwhile, the rotation of the crank 2 is limited by the limiting block 6 to ensure the stable operation of the crank 2 during use.

[0047] Example 4

[0048] like Figure 3-4As shown, this utility model proposes a connection structure for a motorcycle starter lever. Compared with Embodiment 1, the difference in this embodiment is that a rectangular ring 8 connected to the connecting block 7 is sleeved on the outer side of the cap nut 9. One end of the connecting block 7 is provided with a first rectangular groove 14. When the connecting block 7 and the rectangular ring 8 are installed together, the rectangular ring 8 is accommodated in the first rectangular groove 14. This groove is used to limit the rectangular ring 8 during use and to limit the rotation of the cap nut 9, so that the cap nut 9 is fixed at the end of the stud 11, preventing the cap nut 9 from falling off due to vibration or other reasons.

[0049] In an optional embodiment, a magnetic strip 12 is fitted onto the end face of the rectangular ring 8. The magnetic strip 12 is magnetically connected to the connecting block 7, which is used to magnetically connect the rectangular ring 8 to the connecting block 7 during use, so as to prevent the rectangular ring 8 from falling off during the motorcycle's operation.

[0050] In an optional embodiment, a connecting groove 13 is provided on the side of the rectangular ring 8, and a notch 15 is provided at the opening of the first rectangular groove 14 and on one side of the connecting groove 13. The notch 15 is used to separate the rectangular ring 8 from the magnetic strip 12 and the connecting block 7 by cooperating with the connecting groove 13 during use, so that the cap nut 9 can be disassembled.

[0051] In this embodiment, by sleeved on the outside of the cap nut 9 and fitted into the first rectangular groove 14, the inner and outer sides of the rectangular ring 8 generate rotational forces with the outer side of the cap nut 9 and the inner wall of the first rectangular groove 14, respectively. This restricts the rotation of the cap nut 9 within the first rectangular groove 14, thus fixing the cap nut 9 to the end of the stud 11. This effectively prevents the starting rod from falling off under severe vibration, improving the durability and safety of the overall structure.

[0052] In this invention, the bottom end of the crank 2 is fitted onto the outside of the connecting post 3, and the washer 5 is fitted onto the outside of the connecting post 3 above the crank 2. Simultaneously, the position of the washer 5 is limited by the connection between the retaining spring 4 and the connecting post 3, thus ensuring stable support between the connecting post 3 and the crank 2. The rotation of the crank 2 is limited by the limiting block 6, and the connecting block 7 is fitted onto the outside of the rectangular block 10, so that the inner wall of the second rectangular groove 16 is in close contact with the outer side of the rectangular block 10. The stud 11 extends from the second rectangular groove 16 into the inner side of the first rectangular groove 14. Simultaneously, the cap nut 9 is connected to the end of the stud 11 in the first rectangular groove 14, and the rectangular ring 8 is sleeved on the outside of the cap nut 9 and fitted into the first rectangular groove 14. At the same time, the rectangular ring 8 is attracted and connected to the connecting block 7 by the magnetic strip 12, so that the inner and outer sides of the rectangular ring 8 generate rotational forces with the outer side of the cap nut 9 and the inner wall of the first rectangular groove 14, respectively, limiting the rotation of the cap nut 9 and fixing the cap nut 9 to the end of the stud 11. This avoids the situation of falling off due to vibration, making the installation of the crank 2 convenient and quick, and improving the durability and safety of the overall structure.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
