Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and more specifically, to a frame support structure and a scooter. Background Technology

[0002] With urbanization and increasing demand for convenient travel, electric scooters have become an important tool for daily commuting and leisure. However, traditional electric scooters have some design limitations, especially in adapting to different terrains and user needs. For electric scooters, the height adjustment function of the frame (chassis) is an important area for improvement, as it directly affects the vehicle's handling stability, maneuverability, and riding comfort.

[0003] Most electric scooters on the market currently use a fixed frame design, meaning the height of the frame (chassis) relative to the ground is not adjustable. This design provides sufficient stability and speed advantages when riding on flat roads, but its passability is poor when encountering uneven roads or needing to cross obstacles, which can easily lead to vehicle damage or a poor user experience.

[0004] Furthermore, when the scooter is in different riding conditions or when facing users of different heights, a fixed-height frame may not be able to meet the optimal riding posture and comfort, thus affecting the user's riding experience and safety.

[0005] Currently, some scooters with adjustable frame height have emerged. These scooters typically adjust the frame height by loosening or tightening the clamps, which is a relatively complex structure, inconvenient to adjust, and fails to meet users' convenience needs. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a frame support structure and a scooter, which is simple in structure, easy to adjust, and can effectively improve the user experience.

[0007] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0008] A vehicle frame support structure, comprising:

[0009] The frame has a connecting shaft at one end.

[0010] The first rocker arm is connected to the connecting shaft and rotates synchronously with the connecting shaft;

[0011] The second rocker arm includes a first end connected to the first rocker arm and a second end configured to connect to the axle of a wheel.

[0012] At least two connection points are formed between the first rocker arm and the second rocker arm, and the relative angle between the first rocker arm and the second rocker arm is different under different connection points.

[0013] By adjusting the relative angle between the first rocker arm and the second rocker arm at different connection points, the height of the end of the first rocker arm connected to the connecting shaft can be adjusted, thereby adjusting the height of the frame. This allows for adjustment of the frame's ground clearance, meeting the needs of different road conditions and users. It offers greater flexibility and a better user experience. The first and second rocker arms work together to achieve height adjustment. The structure is simple, the operation is convenient, and the use is easy.

[0014] In some embodiments, one of the first rocker arm and the second rocker arm is provided with a first connecting hole, and the other is provided with at least two adjustment holes. The first connecting hole and the at least two adjustment holes can be selectively matched to form different connection positions to adjust the height of the frame.

[0015] At least two adjustment holes are used to assemble with the first connection hole, thereby adjusting the relative angle of the second rocker arm with respect to the first rocker arm by changing the position of the adjustment holes, and thus adjusting the support height of the frame. The structure is simple and easy to operate.

[0016] In some embodiments, the first rocker arm is provided with a first fixing hole and a first connecting hole, and the second rocker arm is provided with a second fixing hole and at least two adjusting holes. The first fixing hole and the second fixing hole are provided correspondingly and connected by a first connector. One of the first connecting hole and the at least two adjusting holes can be selectively connected and connected by a second connector to form at least two connection positions.

[0017] The second rocker arm is selectively assembled with the first connecting hole on the first rocker arm by using at least two adjustment holes. This allows for angle adjustment of the second rocker arm relative to the first rocker arm around the center of the first fixed hole by changing the position of the adjustment holes, thereby adjusting the support height of the frame. The structure is simple and easy to operate.

[0018] In some embodiments, the first rocker arm includes a first connecting section and a first bending section, and the second rocker arm includes a second connecting section and a second bending section. The first bending section and the second bending section are stacked, and the second bending section is located inside the second bending section. A first fixing hole and a first connecting hole are located on the first bending section, and a second fixing hole and at least two adjusting holes are located on the second bending section.

[0019] It can achieve better structural strength by using bending.

[0020] In some embodiments, the surface of the second bending segment away from the first bending segment is flush with or lower than the surface of the first connecting segment away from the first bending segment, and the surface of the first bending segment away from the second bending segment is flush with or lower than the surface of the second connecting segment away from the second bending segment.

[0021] This design ensures that the bent sections of both the first and second rocker arms are located inside the outer surface of the first connecting section, resulting in a more compact overall structure, more efficient use of space, and a better appearance.

[0022] In some embodiments, a stop block is fixedly provided on the frame, and the end of the first rocker arm away from the second rocker arm is provided with a protrusion that protrudes laterally toward the side where the stop block is located. The protrusion can form a stop engagement with the stop block when the frame is pressed down.

[0023] The rocker arm can be restricted by the stop block, thereby limiting the downward pressure position of the frame and ensuring the structural stability and reliability of the frame.

[0024] In some embodiments, the protrusion is a bent plate disposed at the end of the first rocker arm and bent toward the side where the stop block is located; and / or, the stop block is detachably connected to the frame.

[0025] This facilitates the replacement and maintenance of the stop blocks.

[0026] In some embodiments, the second rocker arm is located outside the first rocker arm, and within the angle adjustment range of the first rocker arm relative to the second rocker arm, the portion of the first rocker arm located inside the second rocker arm is blocked by the second rocker arm.

[0027] It can conceal the first rocker arm within the second rocker arm, resulting in a better appearance structure for the cooperation between the first and second rocker arms.

[0028] In some embodiments, the portion of the first rocker arm that engages with the second rocker arm is triangular or trapezoidal, and the portion of the second rocker arm that engages with the first rocker arm is rectangular.

[0029] This allows the second rocker arm to better conceal the mating parts of the first rocker arm, resulting in a better appearance and performance.

[0030] In some embodiments, the first rocker arm and the second rocker arm have a first connection position and a second connection position. When they are in the first connection position, the first rocker arm and the second rocker arm are on the same straight line. When they are in the second connection position, the first rocker arm and the second rocker arm are bent upward at the connection position.

[0031] This makes the force transmission structure more optimized and the structure more stable and reliable.

[0032] In some embodiments, the connecting shaft has an anti-rotation section, the first rocker arm is provided with a mounting hole adapted to the shape of the anti-rotation section, the connecting shaft is also provided with an end nut, the end nut is provided on the outside of the first rocker arm and axially limits the first rocker arm on the connecting shaft; and / or, the frame is provided with a shock absorber, and the connecting shaft is mounted on the shock absorber.

[0033] It can ensure the structural strength of the fit between the first rocker arm and the connecting shaft, while improving the shock absorption effect between the frame and the first rocker arm, thus enhancing the user experience.

[0034] In some embodiments, the first rocker arm is provided with a first fixing hole and at least two adjusting holes, and the second rocker arm is provided with a second fixing hole and a first connector. The first fixing hole and the second fixing hole are correspondingly provided and connected by the first connector. The first connecting hole and one of the at least two adjusting holes can be selectively connected and connected by the second connector.

[0035] It can adjust the height of the frame.

[0036] Another embodiment of this utility model provides a technical solution for a scooter, including a frame support structure, wherein the frame support structure is the frame support structure described above.

[0037] This utility model has the following beneficial effects: The frame support structure rotates synchronously with the first rocker arm through the connecting shaft on the frame, and forms different connection positions between the second rocker arm and the first rocker arm. This results in different relative angles between the second rocker arm and the first rocker arm at different connection positions, thereby achieving height adjustment of the end of the first rocker arm connected to the connecting shaft, and thus achieving height adjustment of the frame support. This allows for adjustment of the frame's ground clearance to meet the needs of different road conditions and users, enabling the scooter to provide better driving stability and user adaptability under different terrain conditions, with higher flexibility and a better user experience. The first rocker arm and the second rocker arm work together to achieve height adjustment, with a simple structure, convenient operation, and easy use. Attached Figure Description

[0054] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0055] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0056] To address the problem of complex cell support structures in existing technologies leading to high assembly difficulty, this utility model provides a cell support and battery pack.

[0057] In some embodiments, such as Figures 1 to 7As shown, the frame support structure includes: a frame 20, one end of which is provided with a connecting shaft 2; a first rocker arm 3, which is connected to the connecting shaft 2 and rotates synchronously with the connecting shaft 2; and a second rocker arm 4, which includes a first end connected to the first rocker arm 3 and a second end configured to be connected to the wheel axle 22. At least two connection positions are formed between the first rocker arm 3 and the second rocker arm 4, and the relative angle between the first rocker arm 3 and the second rocker arm 4 is different under different connection positions.

[0058] The frame support structure, through the circumferential limiting cooperation between the connecting shaft 2 on the frame 20 and the first rocker arm 3, allows the two to rotate synchronously. Different connection points are formed between the second and first rocker arms, resulting in different relative angles between them. This allows the relative angle between the second rocker arm 4 and the first rocker arm 3 in the vertical plane to be adjusted, enabling height adjustment of the end of the first rocker arm 3 connected to the connecting shaft 2. This, in turn, adjusts the support height of the frame 20, thus adjusting the frame's ground clearance to meet the needs of different road conditions and users. This provides the scooter with better driving stability and user adaptability under various terrain conditions, offering greater flexibility and a better user experience. The first and second rocker arms work together to achieve height adjustment; the structure is simple, easy to operate, and convenient to use.

[0059] Specifically, the limiting design of the first rocker arm 3 and the connecting shaft 2 ensures that relative rotation between the first rocker arm 3 and the connecting shaft 2 cannot occur. This ensures the stability and reliability of the support structure of the frame 20 after the first rocker arm 3 and the second rocker arm 4 are connected, facilitating the height adjustment of the frame 20 by adjusting the relative angle between the first rocker arm 3 and the second rocker arm 4. The angle adjustment feature of the second rocker arm 4 relative to the first rocker arm 3 allows users to change the angle relationship between the first rocker arm 3 and the second rocker arm 4 as needed during assembly or use, thereby adjusting the height of the frame 20 and thus changing the distance between the scooter chassis and the ground. When it is necessary to increase the ground clearance, the relative angle between the second rocker arm 4 and the first rocker arm 3 can be adjusted to increase the angle between the second rocker arm 4 and the ground, thereby raising the first rocker arm 3 and thus raising the frame 20. Conversely, adjusting the relative angle between the second rocker arm 4 and the first rocker arm 3 can decrease the angle between the second rocker arm 4 and the ground, thereby lowering the height of the first rocker arm 3 and thus lowering the height of the frame 20.

[0060] In some embodiments, one of the first rocker arm 3 and the second rocker arm 4 is provided with a first connecting hole 6, and the other is provided with at least two adjusting holes 8. The first connecting hole 6 and the at least two adjusting holes 8 can be selectively matched to form different connection positions to adjust the height of the frame 20.

[0061] In this embodiment, the first connecting hole 6 is provided on one of the first rocker arm 3 and the second rocker arm 4, and at least two adjusting holes 8 are provided on the other of the first rocker arm 3 and the second rocker arm 4. By adjusting the matching position of the first connecting hole 6 and the adjusting hole 8, the connection position of the first rocker arm 3 and the second rocker arm 4 can be adjusted, thereby adjusting the height of the frame 20 at the end of the first rocker arm 3.

[0062] The engagement between the first connecting hole 6 and the adjusting hole 8 can take various forms. For example, one first connecting hole 6 can selectively engage with multiple adjusting holes 8, or two first connecting holes 6 can selectively engage with multiple sets of adjusting holes 8, with two adjusting holes 8 in each set, and each set of adjusting holes 8 located on the rotation path of the two first connecting holes 6. This allows the first connecting hole 6 and the adjusting hole 8 to connect at different positions, thereby adjusting the connection position of the first rocker arm 3 and the second rocker arm 4. The engagement between the first connecting hole 6 and the adjusting hole 8 can also take other forms, as long as they achieve the same function of adjusting the connection position of the first rocker arm 3 and the second rocker arm 4.

[0063] In some embodiments, the first rocker arm 3 is provided with a first fixing hole 5 and a first connecting hole 6, and the second rocker arm 4 is provided with a second fixing hole 7 and at least two adjusting holes 8. The centers of the at least two adjusting holes 8 are located on the same circumference with the center of the second fixing hole 7 as the center. The first fixing hole 5 and the second fixing hole 7 are correspondingly provided and connected by a first connector 9. One of the first connecting hole 6 and the at least two adjusting holes 8 can be selectively connected and connected by a second connector 10 to form at least two connection positions.

[0064] At least two adjustment holes 8 are used to assemble with the first connection hole 6. The position change of the adjustment holes 8 can be used to adjust the angle of the second rocker arm 4 relative to the first rocker arm 3 around the center of the first fixed hole 5, thereby adjusting the support height of the frame 20. The structure is simple and easy to operate.

[0065] By designing a first fixing hole 5 and a first connecting hole 6 on the first rocker arm 3, and setting a second fixing hole 7 and multiple circumferentially distributed adjustment holes 8 on the second rocker arm 4, the first rocker arm 3 and the second rocker arm 4 are fixedly connected by the first connector 9. By selectively using the second connector 10 to cooperate with the adjustment holes 8 at different positions, the rocker arm angle can be finely adjusted, thereby effectively adjusting the support height of the frame 20, enhancing the scooter's adaptability to different road conditions and the user's riding comfort, while ensuring the stability of the structure and the convenience of the adjustment process.

[0066] The circumferential distribution of the adjustment holes 8 allows users to adjust the relative angle between the first rocker arm 3 and the second rocker arm 4 simply by changing the connection position of the second connector 10 without disassembling the first connector 9. This adjustment mechanism not only simplifies the operation process but also ensures the stability and reliability of the connection structure between the first rocker arm 3 and the second rocker arm 4 at different support heights, thus guaranteeing the stability and reliability of the connection structure between the first rocker arm 3 and the second rocker arm 4 in supporting the frame 20.

[0067] In one embodiment, the first rocker arm 3 is provided with a first fixing hole 5 and at least two adjusting holes 8, and the second rocker arm 4 is provided with a second fixing hole 7 and a first connecting member 9. The centers of the at least two adjusting holes 8 are located on the same circumference with the center of the second fixing hole 7 as the center. The first fixing hole 5 and the second fixing hole 7 are correspondingly provided and connected by the first connecting member 9. The first connecting hole 6 and one of the at least two adjusting holes 8 can be selectively connected and connected by the second connecting member 10 to form at least two connection positions.

[0068] In this embodiment, two adjustment holes 8 are provided on the first rocker arm 3 and the first connecting hole 6 is provided on the second rocker arm 4. Thus, the support height of the frame 20 can be adjusted by adjusting the swing angle of the first rocker arm 3 relative to the second rocker arm 4. The structure is simple and easy to implement.

[0069] In one embodiment, the number of second fixing holes 7 can also be the same as the number of adjusting holes 8. One second fixing hole 7 and a corresponding adjusting hole 8 form a group of adjusting holes. Multiple groups of adjusting holes can be selectively connected to the first fixing hole 5 and the first connecting hole 6 to adjust the connection position of the first rocker arm 3 and the second rocker arm 4.

[0070] In one embodiment, the first rocker arm 3 and the second rocker arm 4 can also be connected by an anti-rotation rod. The anti-rotation rod has an anti-rotation structure, and its two ends respectively engage with the first rocker arm 3 and the second rocker arm 4 to prevent rotation. The first rocker arm 3 and the second rocker arm 4 each have an anti-rotation hole adapted to the anti-rotation rod, and the anti-rotation rod passes through the anti-rotation hole. The anti-rotation section of the anti-rotation rod has a regular polygonal cross-section. When it is necessary to adjust the relative angle between the first rocker arm 3 and the second rocker arm 4, simply remove the second rocker arm 4 from the anti-rotation rod, rotate it by an angle so that the anti-rotation surface of the second rocker arm 4 is misaligned with the anti-rotation surface of the anti-rotation rod by one surface along the rotation direction of the second rocker arm 4. Then, reinstall the second rocker arm on the anti-rotation rod to achieve adjustment of the connection position and angle of the second rocker arm 4 relative to the first rocker arm 3. Nuts can be fixed to both ends of the anti-rotation rod to achieve axial limitation of the first rocker arm 3 and the second rocker arm 4. The anti-rotation rod can also be bolted at one end and locked with a nut at the other end to achieve axial limiting of the first rocker arm 3 and the second rocker arm 4.

[0071] In one embodiment, the anti-rotation rod can be fixedly connected to the first rocker arm 3 or the second rocker arm 4. When it is necessary to adjust the connection position between the first rocker arm 3 and the second rocker arm 4, it is only necessary to control the second rocker arm 4 to rotate relative to the first rocker arm 3 by an angle so that the second rocker arm 4 reaches the position where the anti-rotation rod can be inserted. Then, the first rocker arm 3 and the second rocker arm 4 are connected together through the anti-rotation rod and fixed by a nut or locking pin.

[0072] See also Figures 5 to 7 As shown, in one embodiment, the first rocker arm 3 includes a first connecting section 11 and a first bending section 12, and the second rocker arm 4 includes a second connecting section 13 and a second bending section 14. The first connecting section 11 is connected to the connecting shaft 2, and the second connecting section 13 is configured to be connected to the wheel axle 22. The first bending section 12 bends inward toward the first connecting section 11, and the second bending section 14 bends outward toward the second connecting section 13. The first bending section 12 and the second bending section 14 are stacked, and the second bending section 14 is located inside the second bending section 14. The first fixing hole 5 and the first connecting hole 6 are located on the first bending section 12, and the second fixing hole 7 and at least two adjusting holes 8 are located on the second bending section 14.

[0073] In this embodiment, the first rocker arm 3 includes a first connecting section 11 and a first bending section 12, and the second rocker arm 4 includes a second connecting section 13 and a second bending section 14. The first bending section 12 bends inward toward the first connecting section 11, and the second bending section 14 bends outward toward the second connecting section 13. This not only enhances the support structure strength of the first rocker arm 3 and the second rocker arm 4 by utilizing the bending structure of the bending section, but also enables the first rocker arm 3 and the second rocker arm 4 to be misaligned, ensuring that both the first rocker arm 3 and the second rocker arm 4 are in a better position that facilitates cooperation with other structures. While ensuring the stability and reliability of the connection structure between the first rocker arm 3 and the second rocker arm 4, the overall structure is made more compact.

[0074] The combination of the inward bending of the first bending section 12 and the outward bending of the second bending section 14 ensures a compact layout of the two rocker arms in the stacked state. Through the circumferential distribution of the adjustment holes, the second rocker arm 4 can be connected at different angles around the circumference centered on the second fixing hole 7. This flexible adjustment mechanism provides the scooter with highly customizable features, meeting the needs of users in different usage scenarios.

[0075] In one embodiment, the surface of the second bending segment 14 away from the first bending segment 12 is at the same height as or lower than the surface of the first connecting segment 11 away from the first bending segment 12, and the surface of the first bending segment 12 away from the second bending segment 14 is at the same height as or lower than the surface of the second connecting segment 13 away from the second bending segment 14.

[0076] This ensures that the surface height of the second bending section 14 is level with or slightly lower than the surface height of the first connecting section 11, and that the surface height of the first bending section 12 is level with or lower than the surface height of the second connecting section 13. This ensures that the entire frame support structure can maintain a neat appearance and compact space occupation during the rocker arm angle adjustment process, while avoiding any unnecessary interference between components, ensuring the smoothness of the adjustment action and the structural stability of the entire system.

[0077] In addition, the above structure ensures that the bending sections of both the first rocker arm and the second rocker arm are located inside the surface of the first connecting section, resulting in a more compact overall structure, more efficient use of space, and a better appearance.

[0078] In one embodiment, the second rocker arm 4 is located outside the first rocker arm 3, and within the angle adjustment range of the first rocker arm 3 relative to the second rocker arm 4, the portion of the first rocker arm 3 located inside the second rocker arm 4 is completely blocked by the second rocker arm 4.

[0079] By positioning the second rocker arm 4 outside the first rocker arm 3, and ensuring that the portion of the first rocker arm 3 located inside the second rocker arm 4 is covered by the second rocker arm 4 during angle adjustment, the cooperative structure of the first rocker arm and the second rocker arm forms a better appearance structure, which can present a cleaner and more integrated appearance, enhancing the user's visual satisfaction.

[0080] In one embodiment, the portion where the first rocker arm 3 and the second rocker arm 4 cooperate is triangular or trapezoidal, and the portion where the second rocker arm 4 and the first rocker arm 3 cooperate is rectangular. During the design of the first bending segment 12 of the first rocker arm 3, the width of the apex of the triangle or the narrow side of the trapezoid can be reasonably designed based on the rectangular structure width of the second bending segment 14 of the second rocker arm 4 and the maximum width of the first bending segment 12. This ensures that the first bending segment 12 remains within the obstruction range of the second bending segment 14 throughout the entire angle adjustment process, resulting in superior aesthetic performance.

[0081] In one embodiment, the first rocker arm 3 has a first connection position and a second connection position relative to the second rocker arm 4. When they are in the first connection position, the first rocker arm 3 and the second rocker arm 4 are on the same straight line. When they are in the second connection position, the first rocker arm 3 and the second rocker arm 4 are bent upward at the connection position.

[0082] In the linkage system formed by the first rocker arm 3 and the second rocker arm 4, by changing the relative angle between the two rocker arms, the straight arrangement of the first connection position transitions to the upward bending of the second connection position to form an upward posture, which cleverly realizes the convenient adjustment of the frame chassis height and enhances the adaptability of the scooter to various road conditions. Especially when encountering potholes, slopes, or scenarios where it is necessary to increase the ground clearance, the upward movement of the rocker arms at the second relative angle can provide more effective and stable support for the frame 20.

[0083] The adjustment of the connection between the first rocker arm 3 and the second rocker arm 4 is achieved by selectively connecting the adjustment hole 8 on the second rocker arm 4, thereby changing the connection point of the two rocker arms and thus altering the tilt of the first rocker arm 3. In the first connection position, the two rocker arms are almost on the same plane, providing a lower chassis height suitable for high-speed driving on flat terrain. When switching to the second connection position, the interaction between the bending section and the connection section of the rocker arm causes the connection position to rise, increasing the chassis ground clearance and effectively addressing the challenges of complex road conditions. This also optimizes the force transmission structure, making the structure more stable and reliable.

[0084] In one embodiment, the connecting shaft 2 has an anti-rotation section 17, the first rocker arm 3 is provided with a mounting hole 18 that matches the shape of the anti-rotation section 17, and the connecting shaft 2 is also provided with an end nut 19, which is located on the outside of the first rocker arm 3 and axially limits the first rocker arm 3 on the connecting shaft 2.

[0085] By precisely matching the anti-rotation section 17 of the connecting shaft 2 with the mounting hole 18 on the first rocker arm 3, and supplemented by the axial limiting effect of the end nut 19, the first rocker arm 3 is stably positioned and anti-rotationally secured on the connecting shaft 2. This ensures a stable and reliable anti-rotation fit between the connecting shaft 2 and the first rocker arm 3, thereby enabling the second rocker arm 4 to stably support the connecting shaft 2, and ultimately providing stable support for the frame 20. The anti-rotation section 17 of the connecting shaft 2 is integrally formed by a section of the connecting shaft 2, resulting in higher structural strength and a better anti-rotation effect with the first rocker arm 3. This effectively reduces the probability of deformation of the anti-rotation structure during the support of the frame 20, improving the stability and reliability of the anti-rotation fit.

[0086] The cross-section of the aforementioned anti-rotation section 17 is polygonal or other non-circular structure, such as ellipse, or a combination of arc and straight lines, as long as it satisfies the requirement of achieving anti-rotation fit between the anti-rotation section 17 and the mounting hole 18. The cross-sectional shape of the mounting hole 18 is adapted to the cross-sectional shape of the anti-rotation section 17.

[0087] In some embodiments, a rotational fit structure can also be adopted between the connecting shaft 2 and the first rocker arm 3, and then an anti-rotation fit between the connecting shaft 2 and the first rocker arm 3 can be achieved by setting an anti-rotation pin or the like between the connecting shaft 2 and the first rocker arm 3.

[0088] See also Figures 3 to 5 As shown, in one embodiment, a stop block 15 is fixedly provided on the frame 20, and a protrusion 16 is provided at the end of the first rocker arm 3 away from the second rocker arm 4, which protrudes laterally toward the side where the stop block 15 is located. The protrusion 16 can form a stop engagement with the stop block 15 when the frame 20 is pressed down, and limit the pressing position of the frame 20.

[0089] After the relative angle adjustment of the first rocker arm 3 and the second rocker arm 4 is completed, the frame 20 is pressed down, and the connecting shaft 2 can rotate relative to the frame 20. During the pressing down of the frame 20, the side of the first rocker arm 3 that rotates synchronously with the connecting shaft 2 away from the second rocker arm 4 is pressed down. When the protrusion 16 on the first rocker arm 3 moves to the position of the stop block 15, the stop block 15 can be used to stop the protrusion 16, thereby limiting the rotation position of the first rocker arm 3, and thus limiting the pressing position of the frame 20, so that the frame can be kept at the preset height, ensuring that the support structure of the frame is stable and reliable.

[0090] In one embodiment, the protrusion 16 is a bent plate located at the end of the first rocker arm 3 and bent toward the side where the stop block 15 is located.

[0091] By providing a protrusion 16, or bending plate, bent towards the stop block 15 at the end of the first rocker arm 3, the rotation range of the first rocker arm 3 is effectively limited, preventing it from rotating excessively and deviating from its normal operating range. This ensures safety and stability during rocker arm adjustment, simplifies the design of the rocker arm angle control mechanism, and improves the compactness and reliability of the entire frame support structure. The bending plate can be directly bent from the end of the first rocker arm 3, resulting in a simple structure, ease of operation, and low cost.

[0092] As a physical limiting device, the protrusion 16 can contact the stop block 15 when the first rocker arm 3 reaches the expected maximum rotation angle, preventing the first rocker arm 3 from rotating further and providing a stopping force for the first rocker arm 3. This allows the frame 20 to be effectively limited in its downward position under the combined action of the first rocker arm 3 and the stop block 15 when it is pressed down, thus keeping the frame 20 at a preset height position and making the structure more stable and reliable.

[0093] In one embodiment, the stop block 15 is detachably connected to the frame 20. The stop block 15 and the frame 20 form a detachable connection structure, which facilitates the replacement and maintenance of the stop block and reduces maintenance costs.

[0094] In one embodiment, a shock absorber 21 is provided on the frame 20, and the connecting shaft 2 is mounted on the shock absorber 21.

[0095] Shock absorbers 21 are provided at the ends of the frame 20, and the connecting shaft 2 is mounted on the shock absorbers 21. This effectively absorbs and reduces vibrations caused by uneven or bumpy ground when the scooter is running. When uneven or bumpy ground causes the roller 23 to vibrate, the vibration of the roller 23 is transmitted to the connecting shaft 2 by the second rocker arm 4 and the first rocker arm 3, and then to the shock absorber 21 by the connecting shaft 2. The shock absorber 21 absorbs the vibration transmitted by the connecting shaft 2, thereby greatly reducing the vibration transmitted to the frame 20 through the shock absorber 21 and improving the user experience.

[0096] In this embodiment, a wheel axle 22 is rotatably mounted on the roller 23, and the end of the second rocker arm 4 away from the first rocker arm 3 forms an anti-rotation fit with the wheel axle 22.

[0097] According to an embodiment of the present invention, the scooter includes a frame support structure 1, which is the frame support structure described above.

[0098] In one embodiment, the frame support structure is located on the front or rear side of the scooter.

[0099] In one embodiment, a frame support structure is provided on the front and rear sides of the scooter, respectively.
