Description

Technical Field

[0001] The present invention relates to the technical field of scooters, and more particularly, to a scooter frame and a scooter. Background Art

[0002] With the development of urbanization and the increasing demand for convenient travel methods, electric scooters have become one of the important tools for daily commuting and leisure. However, traditional electric scooters have some limitations in design, especially in adapting to different terrains and user needs. For electric scooters, the height adjustment function of the frame (chassis) is an important improvement direction, which directly affects the handling stability, passability, and riding comfort of the vehicle.

[0003] Most of the electric scooters on the market currently adopt a fixed frame design, that is, the height of the frame (chassis) relative to the ground is not adjustable. This design can provide sufficient stability and speed advantages when driving on flat roads, but when encountering uneven roads or obstacles, its passability is poor, which is likely to cause vehicle damage or poor user experience.

[0004] In addition, when the scooter is in different driving states or facing users of different heights, the fixed-height frame may not be able to meet the best driving posture and comfort, thus affecting the riding experience and safety of users.

[0005] Currently, there are some scooters that can adjust the frame height. Generally, this type of scooter adjusts the frame height by loosening or tightening the hoop, with a relatively complex structure and inconvenient adjustment, making it difficult to meet the convenience needs of users. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a scooter frame and a scooter, which have a simple structure, convenient adjustment, and can effectively improve the user experience.

[0007] To achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0008] A scooter frame, comprising:

[0009] A mounting bracket having a connecting shaft;

[0010] An angle block mounted on the connecting shaft and forming an anti-rotation fit with the connecting shaft;

[0011] A rocker arm, the first end of which can be connected to the connecting shaft. An installation groove is provided at the first end of the rocker arm, and at least two installation positions with different heights are formed along the circumferential direction of the connecting shaft. The angle block can be selectively installed in different installation positions and fixedly connected to the rocker arm;

[0012] The wheel includes an axle, and the second end of the rocker arm can be connected to the axle.

[0013] The scooter frame realizes the adjustment of different support height positions of the rocker arm by the rotational cooperation of the angle block and the rocker arm, thereby realizing the adjustment of the ground clearance between the front frame and the ground, being able to adapt to different road conditions, and can be adapted to users of different heights, which can improve the user experience. The scooter frame realizes the height adjustment effect by using the rocker arm. By adopting the rocker arm structure to adjust the ground clearance between the front frame and the ground, only by adjusting the cooperation position of the angle block and the rocker arm can the height of the front frame be adjusted. The structure is simple and the operation is convenient, which can better meet the convenience needs of users.

[0014] In some embodiments, the angle block is provided with connection holes, each installation position is provided with at least one adjustment hole, and the adjustment holes of different installation positions can be selectively communicated with the connection holes. The scooter frame further includes a connecting piece, and the connecting piece is inserted into the corresponding connection holes and adjustment holes and fixedly connects the angle block and the rocker arm.

[0015] The detachable connection and fixation between the angle block and the rocker arm are realized through the connecting piece, and the operation is simple and convenient, and it is more convenient and fast.

[0016] In some embodiments, each installation position is provided with one adjustment hole, and the centers of the adjustment holes of different installation positions are located on the same circumference with the central axis of the connecting shaft as the center of the circle.

[0017] Only one connection hole can realize the cooperation with multiple adjustment holes. The structure is simple, the processing process is less, and the cost is low. In some embodiments, the number of installation grooves is at least two, at least two installation grooves are arranged adjacent to each other and partially communicated, and a spaced projection is formed at one end away from the connecting shaft between two adjacent installation grooves.

[0018] The spaced projection can be used to make the angle block obtain more effective side wall support at each installation position, with better structural strength and better stability.

[0019] In some embodiments, the shape of the installation groove is adapted to the angle block; and / or, the depth of the installation groove is greater than the thickness of the angle block.

[0020] It can further increase the cooperation area between the angle block and the rocker arm, improve the uniformity of force distribution, reduce local stress concentration, and provide a more stable and reliable support effect.

[0021] In some embodiments, the number of installation grooves is one, and the end wall at one end of the installation groove away from the connecting shaft forms a plane or an arc surface.

[0022] Multiple installation positions with different heights are formed in one installation groove to match the height adjustment of different mounting brackets.

[0023] In some embodiments, the groove wall of the mounting groove can support the angle block when the angle block is fixedly connected to the rocker arm.

[0024] It can improve the support structure strength of the rocker arm for the angle block, and can increase the contact area at the mating position between the angle block and the rocker arm, making the contact area between the two larger and the force distribution more uniform. The lower side wall of the end of the mounting groove away from the connecting shaft forms a support for the angle block.

[0025] In some embodiments, the angle block is provided with a convex column protruding towards the rocker arm corresponding to the connecting shaft. A shaft hole is provided in the convex column, the connecting shaft is located in the shaft hole, and a mounting hole is provided on the rocker arm corresponding to the convex column. The convex column is mounted in the mounting hole.

[0026] The use of the convex column enhances the thickness of the angle block, enhances the structural strength of the fit between the angle block and the connecting shaft, improves the support capacity of the angle block, and at the same time makes it more convenient to realize the rotational adjustment between the angle block and the rocker arm.

[0027] In some embodiments, a connecting screw is provided at the end of the connecting shaft. The mounting hole has a countersunk head groove, and a connecting nut is provided in the countersunk head groove. The connecting nut is fixedly connected to the connecting screw.

[0028] The connecting nut is located in the countersunk head groove, which can prevent the connecting nut from protruding outside the rocker arm, improve the appearance, and also prevent the connecting nut from hooking other objects.

[0029] In some embodiments, the connecting shaft includes a multi-faceted shaft section, and the angle block has a multi-faceted hole. The multi-faceted shaft section is mounted in the multi-faceted hole and is adapted to the multi-faceted hole.

[0030] It is convenient to realize the anti-rotation fit between the angle block and the connecting shaft, and the structural strength is higher.

[0031] In some embodiments, a shock absorber is provided at the end of the mounting bracket, and the connecting shaft is provided on the shock absorber.

[0032] It can improve the shock absorption effect between the mounting bracket and the wheel.

[0033] In some embodiments, along the axial direction of the connecting shaft, the angle block is arranged on the outer side or the inner side of the rocker arm; and / or, along the direction away from the connecting shaft, the width of the angle block decreases.

[0034] It can improve the flexibility of the angle block setting structure, reduce the required width of the rocker arm, and make the structural volume of the rocker arm occupy less space.

[0035] In some embodiments, the angle block and the rocker arm are connected by a quick-release bolt.

[0036] It can further improve the convenience of adjusting the height of the front frame, reduce the operation difficulty, and improve the user experience.

[0037] Another embodiment of the present invention provides a scooter, including a scooter frame, and the scooter frame is the above-mentioned scooter frame.

[0038] The present invention has the following beneficial effects: The scooter frame realizes the adjustment of different support height positions of the rocker arm by the rotational cooperation of the angle block and the rocker arm, thereby realizing the adjustment of the ground clearance between the front frame and the ground. It can adapt to different road conditions and can be adapted to users of different heights, which can improve the user experience. The scooter frame realizes the height adjustment effect by using the rocker arm. By adopting the rocker arm structure to realize the adjustment of the ground clearance between the front frame and the ground, only by adjusting the cooperation position of the angle block and the rocker arm can the height adjustment of the front frame be realized. The structure is simple and the operation is convenient, which can better meet the convenience needs of users. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0063] The technical solutions in the present invention will be described below with reference to the accompanying drawings.

[0064] To solve the problem that in the prior art, the height of the scooter frame is generally adjusted by loosening or clamping a hoop, the structure is relatively complex, the adjustment is inconvenient, and it is difficult to meet the convenience requirements of users, the present invention provides a scooter frame and a scooter.

[0065] In some embodiments, as Figures 1 to 14 shown, the scooter frame includes a mounting bracket 1, an angle block 3, a swing arm 5, and a wheel 8.

[0066] In some embodiments, the mounting bracket 1 has a connecting shaft 2; the angle block 3 is mounted on the connecting shaft 2 and forms an anti-rotation fit with the connecting shaft 2; the first end of the rocker arm 5 can be connected to the connecting shaft 2, the rocker arm 5 is provided with a mounting groove 6, and the mounting groove 6 forms at least two mounting positions 7 with different heights along the circumferential direction of the connecting shaft 2. The angle block 3 can be selectively mounted at different mounting positions 7 and fixedly connected to the rocker arm 5; the wheel 8 includes a wheel axle 9, and the second end of the rocker arm 5 can be connected to the wheel axle 9.

[0067] The scooter frame realizes the adjustment of different support height positions of the rocker arm 5 by the rotational cooperation between the angle block 3 and the rocker arm 5, thereby realizing the adjustment of the ground clearance between the front frame and the ground, being able to adapt to different road conditions, and can be adapted to users of different heights, which can improve the user experience. The scooter frame realizes the height adjustment effect by using the rocker arm 5. By adopting the rocker arm structure to realize the adjustment of the ground clearance between the front frame and the ground, only by adjusting the cooperation position between the angle block 3 and the rocker arm 5 can the height adjustment of the front frame be realized. The structure is simple and the operation is convenient, which can better meet the convenience needs of users.

[0068] In one embodiment, the scooter frame is provided with the angle block 3 and the rocker arm 5 only on one side of the mounting bracket 1, and realizes the adjustment of different support height positions of the rocker arm 5 by using the angle block 3 and the rocker arm 5 on one side. The number of required parts is small, the adjustment structure is simple, and the operation is more rapid and convenient.

[0069] In one embodiment, the scooter frame is provided with a set of angle block 3 and rocker arm 5 on each side of the mounting bracket 1 respectively. The two sets of angle block 3 and rocker arm 5 located on both sides of the mounting bracket 1 act together to realize the adjustment of different support height positions of the rocker arm 5, which can make the support structure for realizing the height adjustment of the mounting bracket 1 more stable and reliable.

[0070] The two sets of angle block 3 and rocker arm 5 are symmetric about the symmetry plane of the mounting bracket 1, so as to form a more stable and uniform supporting effect on the mounting bracket 1.

[0071] In one embodiment, along the axial direction of the connecting shaft 2, in the same set of angle block 3 and rocker arm 5, the angle block 3 is arranged on the outer side or the inner side of the rocker arm 5, which is convenient for the assembly between the angle block 3 and the rocker arm 5 and makes the setting structure of the angle block 3 more flexible.

[0072] In one embodiment, along the direction away from the connecting shaft 2, the width of the angle block 3 decreases, which can reduce the width of the mounting position on the rocker arm 5 for cooperating with the angle block 3, thereby reducing the overall width of the rocker arm 5, requiring less material and having lower cost.

[0073] See in combination Figures 7 to 14As shown, in some embodiments, the mounting groove 6 forms at least two mounting positions 7 with different heights along the circumferential direction of the connecting shaft 2, including at least two cases. The first case is that one ends of at least two mounting positions close to the wheel shaft 9 are located at different height positions of the same mounting groove 6, thereby forming mounting positions with different heights. The second case is that the number of mounting grooves 6 is multiple, and one ends of the multiple mounting grooves 6 close to the wheel shaft 9 are located at different height positions, and each mounting groove 6 forms a mounting position.

[0074] Referring to Figures 4 to 9 As shown, in some embodiments, the angle block 3 is provided with a connecting hole 4, each mounting position 7 is provided with at least one adjusting hole 12, and the adjusting holes 12 of different mounting positions 7 can be selectively communicated with the connecting hole 4. The scooter frame further includes a connecting member 13, and the connecting member 13 is inserted into the correspondingly provided connecting hole 4 and adjusting hole 12, and fixedly connects the angle block 3 and the swing arm 5.

[0075] By providing the connecting hole 4 on the angle block 3 and configuring at least one adjusting hole 12 at each mounting position 7, the angle block 3 can be selectively communicated with the adjusting holes 12 at different positions as needed. Then, by using the connecting member 13 to pass through the corresponding connecting hole 4 and adjusting hole 12, a firm connection between the angle block 3 and the swing arm 5 at multiple preset angles is achieved. This structural design allows the user to easily adjust the height of the scooter frame to adapt to different road conditions and personal riding preferences, effectively improving the flexibility and comfort of the scooter, while also ensuring the stability and safety of the system at various height settings.

[0076] One end of the swing arm 5 is rotatably connected to the connecting shaft 2, and the other end is rotatably connected to the wheel shaft 9, which facilitates directly adjusting the rotation angle of the swing arm 5 relative to the connecting shaft 2 when adjusting the height of the mounting bracket 1. At this time, the angle block 3 is located outside the mounting groove 6 and will not hinder the rotation adjustment of the swing arm 5 relative to the connecting shaft 2. When the rotation angle of the swing arm 5 relative to the connecting shaft 2 is adjusted to a preset position, the angle block 3 can be installed at the corresponding mounting position 7, and the angle block 3 and the swing arm 5 are fixedly connected through the connecting member 13 to fix the height of the mounting bracket 1.

[0077] The angle block 3 and the swing arm 5 are detachably connected through the connecting member 13, and the operation is simpler and more convenient, and the height adjustment of the mounting bracket 1 is more convenient and rapid.

[0078] In some embodiments, the connecting member 13 is, for example, a bolt or a screw, and can also be a locking pin or the like.

[0079] Referring to Figures 4 to 9 As shown, in some embodiments, each mounting position 7 is provided with one adjusting hole 12, and the centers of the adjusting holes 12 of different mounting positions 7 are located on the same circumference with the central axis of the connecting shaft 2 as the center of the circle.

[0080] In this embodiment, only one connecting hole 4 can achieve selective cooperation with multiple adjusting holes 12. The structure is simple, the processing technology is less, the cost is low, it is easy to implement, and the operation is simple and convenient.

[0081] In some embodiments, the number of connecting holes 4 is at least two. The number of adjusting holes 12 at each mounting position 7 is the same as the number of connecting holes 4 and the positions are matched, so that each mounting position can achieve one-to-one connection and cooperation between the connecting hole 4 and the adjusting hole 12. By matching multiple connecting holes 4 with adjusting holes 12, multiple connecting pieces 13 can be used for connection, which can further improve the connection strength between the angle block 3 and the rocker arm 5 and improve the stability and reliability of the connection structure between the two.

[0082] In one embodiment, the groove wall of the mounting groove 6 can support the angle block 3 when the angle block 3 and the rocker arm 5 are fixedly connected.

[0083] The angle block 3 can be supported by the groove wall of the mounting groove 6 at different mounting positions. This can not only improve the support structure strength of the rocker arm 5 for the angle block 3, but also increase the contact area at the mating position between the angle block 3 and the rocker arm 5, making the contact area between the two larger and the force distribution more uniform. Thus, local stress concentration can be reduced, which is more conducive to adjusting the ground clearance of the mounting bracket through the cooperation of a single rocker arm 5 and the angle block 3.

[0084] In this embodiment, when the mounting bracket 1 is pressed down, the pressure acts on the connecting shaft 2. The connecting shaft 2 has a tendency to descend under the action of the pressure. When the connecting shaft 2 descends, the rocker arm 5 needs to rotate relative to the connecting shaft 2 to achieve the descending action. Since there is an anti-rotation fit between the angle block 3 and the connecting shaft 2 and the angle block 3 and the rocker arm 5 are fixedly connected, the angle block 3 cannot move relative to the rocker arm 5, so that the connecting shaft 2 cannot rotate relative to the rocker arm 5. Therefore, the connecting shaft 2 cannot descend under the blocking action of the angle block 3. The pressure is transmitted to the wheel axle 9 of the wheel 8 through the rocker arm 5, realizing the support of the wheel axle 9 for the mounting bracket 1, so that the mounting bracket 1 can be stably maintained at the current position.

[0085] The groove wall of the mounting groove 6 can support the angle block 3 when the angle block 3 and the rocker arm 5 are fixedly connected, and can use the side wall of the mounting groove 6 to bear the shear force of the angle block 3 relative to the rocker arm 5, thereby reducing or eliminating the shear force received by the connecting piece 13 connecting the angle block 3 and the rocker arm 5. Since the side wall structure of the mounting groove 6 has higher strength and a larger support area, it has a better support effect on the angle block 3. It can not only improve the stability and reliability of the cooperation structure between the angle block 3 and the rocker arm 5, making the structure of the mounting bracket 1 more stable and reliable, but also reduce the influence of the shear force on the connecting piece 13 etc., and extend the service life of the connecting piece 13.

[0086] Refer to the combination of Figures 13 to 14 As shown, in one embodiment, the number of the mounting grooves 6 is one, and the end wall 11 at the end of the mounting groove 6 away from the connecting shaft 2 forms a plane or an arc surface.

[0087] In this embodiment, the mounting groove 6 is arranged in the aforementioned first manner, that is, the number of the mounting grooves 6 is one, and a plurality of mounting positions 7 are arranged in one mounting groove 6. The heights of the plurality of mounting positions 7 are different at the end away from the connecting shaft 2, so that a plurality of mounting positions with different heights are formed in one mounting groove 6 to match the height adjustment of different mounting frames 1.

[0088] In one embodiment, the end wall 11 supports the angle block 3.

[0089] When the number of the mounting grooves 6 is set to one, and the end away from the connecting shaft 2 forms a plane or an arc surface through the end wall 11, the end wall 11 can effectively support the angle block 3 to ensure that after the swing arm 5 rotates relative to the connecting shaft 2 and adjusts the height of the vehicle frame, the angle block 3 is installed at the predetermined mounting position 7. The end wall 11 is used to effectively support the angle block 3, and at the same time, the angle block 3 is connected to the swing arm 5 through the connecting piece 13, so that at least a part of the shear force between the angle block 3 and the swing arm 5 can be borne by the end wall 11, enhancing the reliability of the whole structure and the firmness of the installation of the angle block 3, and finally achieving the effect of flexible adjustment of the vehicle frame height and stable structure.

[0090] Refer to the combination of Figures 11 to 12 As shown, in one embodiment, the number of the mounting grooves 6 is at least two. At least two mounting grooves 6 are arranged adjacent to each other and partially communicate, and a spaced projection 10 is formed at the end of the mounting groove 6 away from the connecting shaft 2.

[0091] In this embodiment, the mounting groove 6 is arranged in the aforementioned second manner, that is, the number of the mounting grooves 6 is multiple. The heights of the multiple mounting grooves 6 are different at the end away from the connecting shaft 2, and each mounting groove 6 forms a mounting position, so that a plurality of mounting positions with different heights are formed by the multiple mounting grooves 6 to match the height adjustment of different mounting frames 1.

[0092] In one embodiment, the lower side walls at the ends of two adjacent mounting grooves 6 away from the connecting shaft 2 support the angle block 3.

[0093] Forming a spaced projection 10 at the end of the mounting groove 6 away from the connecting shaft 2 can support the angle block 3 by the side wall of the spaced projection 10, increase the contact area between the swing arm 5 and the angle block 3, so that the angle block 3 can be more effectively supported by the side wall at each mounting position 7, enhance the structural strength of the cooperation between the swing arm 5 and the angle block 3, further reduce the shear action on the connecting piece 13 at the connecting position between the angle block 3 and the swing arm 5, and improve the stability and reliability of the cooperation structure between the angle block 3 and the swing arm 5.

[0094] In some embodiments, when the number of the mounting grooves 6 is plural, two adjacent mounting grooves 6 communicate with each other on the side close to the connecting shaft 2, so that the structural occupation of the mounting grooves 6 in the width direction of the rocker arm 5 can be reduced, and the width of the rocker arm 5 can be reduced.

[0095] Referring to Figures 4 to 6 As shown, in some embodiments, the connecting shaft 2 includes a multi-faceted shaft section, and the angle block 3 has multi-faceted holes. The multi-faceted shaft section is installed in the multi-faceted holes and is adapted to the multi-faceted holes.

[0096] The connecting shaft 2 is provided with a multi-faceted shaft section, and the angle block 3 is provided with multi-faceted holes adapted to the multi-faceted shaft section, so that the multi-faceted shaft section can be installed in the multi-faceted holes, which is convenient to realize the anti-rotation cooperation between the angle block and the connecting shaft, and the structural strength is higher.

[0097] The multi-faceted shaft section can be a multi-prism structure such as a triangular prism or a quadrangular prism, or a multi-faceted structure surrounded by a plurality of arc surfaces.

[0098] In some embodiments, the anti-rotation cooperation between the connecting shaft 2 and the angle block 3 can also be realized by a radial pin or the like.

[0099] Referring to Figures 4 to 6 As shown, in some embodiments, the angle block 3 is provided with a convex column 14 protruding towards the rocker arm 5 corresponding to the connecting shaft 2. A shaft hole 15 is formed in the convex column 14. The connecting shaft 2 is located in the shaft hole 15. An installation hole 16 is formed in the rocker arm 5 corresponding to the convex column 14, and the convex column 14 is installed in the installation hole 16.

[0100] The angle block 3 is designed with a convex column 14 protruding towards the rocker arm 5, and a shaft hole 15 is formed in the convex column 14, so that the connecting shaft 2 can be accurately embedded in the shaft hole 15 to form an anti-rotation cooperation with the convex column 14, so that a synchronous rotation structure is formed between the angle block 3 and the connecting shaft 2. In addition, the convex column 14 increases the thickness of the angle block 3 in the axial direction of the connecting shaft 2, so that the thickness of the angle block 3 at the connection position with the connecting shaft 2 can be enhanced, the structural strength of the cooperation between the angle block 3 and the connecting shaft 2 can be enhanced, and the anti-rotation support ability of the angle block 3 for the connecting shaft 2 can be improved.

[0101] The mounting hole 16 on the swing arm 5 is aligned and mounted with the convex post 14, and can form a rotational fit. When the swing arm 5 needs to rotate relative to the connecting shaft 2 to adjust the height of the mounting bracket 1, the plate body of the angle block 3 can be withdrawn from the mounting groove 6 of the swing arm 5, so that the swing arm 5 is sleeved on the convex post 14, and the rotational position can be directly adjusted. Since the plate body of the angle block 3 is no longer inside the swing arm 5, it will not hinder the rotational adjustment of the swing arm 5 relative to the connecting shaft 2, enhancing the adaptability and maneuverability of the scooter. Since the swing arm 5 is sleeved on the convex post 14 and is in direct contact with the convex post 14, and does not contact the connecting shaft 2, the wear and other effects caused by the rotational action of the swing arm 5 relative to the connecting shaft 2 directly act on the angle block 3 and will not act on the connecting shaft 2, which can effectively protect the connecting shaft 2. When the convex post 14 of the angle block 3 is worn too much and needs to be replaced, only the angle block 3 needs to be replaced, which is convenient for replacement and maintenance and has a low cost.

[0102] In one embodiment, the shape of the mounting groove 6 is adapted to the angle block 3.

[0103] The shape of the mounting groove 6 is precisely matched with the angle block 3, ensuring that the angle block 3 can be stably and accurately positioned in the mounting groove 6, avoiding the phenomenon of the angle block 3 shaking or misaligning in the groove due to unsuitable shape, making the contact area between the angle block 3 and the side wall of the mounting groove 6 larger, increasing the mating area between the angle block 3 and the swing arm 5, improving the uniformity of the force distribution between the angle block 3 and the swing arm 5, reducing local stress concentration, and providing a more stable and reliable support effect.

[0104] In one embodiment, the depth of the mounting groove 6 is greater than the thickness of the angle block 3.

[0105] The depth of the mounting groove 6 is designed to be deeper than the thickness of the angle block 3, ensuring the stable embedding of the angle block 3 in the mounting groove 6. It can not only further increase the contact area between the angle block 3 and the groove wall of the mounting groove 6, making the mounting groove 6 provide a more stable and reliable support for the angle block 3, improving the uniformity of the force distribution, reducing local stress concentration, and providing a more stable and reliable support effect, but also make the angle block 3 completely located inside the mounting groove 6 and not protrude outside the mounting groove 6, effectively avoiding the problem of easy interference with other structures caused by the protrusion of the angle block 3, and having a better appearance.

[0106] Combined with referring to Figures 1 to 3 As shown in the figure, in one embodiment, a connecting screw 17 is provided at the end of the connecting shaft 2. The mounting hole 16 has a countersunk head groove 18, and a connecting nut 19 is provided in the countersunk head groove 18. The connecting nut 19 is fixedly connected with the connecting screw 17.

[0107] The connecting screw 17 at the end of the connecting shaft 2 cooperates with and is fixed to the connecting nut 19 provided in the countersunk groove 18 in the mounting hole 16 on the rocker arm 5. The connecting nut 19 can be used to connect and fix the rocker arm 5 to the connecting shaft 2, and the countersunk groove 18 can be used to hide the connecting nut 19, which not only provides a more stable connection method and ensures the structural rigidity and reliability of the scooter frame during height adjustment, but also provides a better outer tube, reduces the problem of the connecting nut 19 and clothes being hooked when the connecting nut 19 extends out of the rocker arm 5, improves the overall design sense of the scooter and the comfort in actual use, and the connection method between the screw and the nut is also convenient for disassembly, assembly and maintenance.

[0108] In some embodiments, in order to facilitate the user to adjust the height of the mounting frame 1 during use, the connecting screw 17 can be a manually operable bolt, or a tool box can be provided on the scooter, and operating tools such as a wrench can be assembled in the tool box.

[0109] In some embodiments, a recessed groove 21 is provided on the side of the rocker arm 5 away from the mounting groove 6, and the adjustment hole 12 and the mounting hole 16 are both located within the region of the recessed groove 21. The recessed groove 21 can provide a space for accommodating the connector 13 and the connecting nut 19, so that the connector 13 and the connecting nut 19 are both located within the recessed groove 21 and will not protrude from the surface of the rocker arm 5 away from the mounting groove 6. This not only provides a good appearance, but also avoids safety issues caused by the protrusion of the connector 13 and the connecting nut 19.

[0110] In one embodiment, the rocker arm 5 also includes a decorative cover arranged at the groove 21, and the decorative cover is arranged outside the connecting piece 13 and the connecting nut 19, which can cover the groove 21 while covering the connecting piece 13 and the connecting nut 19, so that the rocker arm 5 has a better appearance, and can further prevent the connecting piece 13 and the connecting nut 19 from being hooked during use by the user, thereby improving the reliability of the scooter.

[0111] In some embodiments, a shock absorber 20 is disposed at the end of the mounting frame 1 , and the connecting shaft 2 is disposed on the shock absorber 20 .

[0112] A shock absorber 20 is disposed at the end of the mounting frame 1, and the connecting shaft 2 is mounted on the shock absorber 20, which can effectively absorb and reduce the vibration caused by uneven or bumpy ground when the scooter is running. When the uneven or bumpy ground causes the wheel 8 to vibrate, the vibration of the wheel 8 is transmitted to the connecting shaft 2 by the rocker arm 5, and then transmitted to the shock absorber 20 by the connecting shaft 2. The shock absorber 20 absorbs the vibration transmitted by the connecting shaft 2, thereby greatly reducing the vibration transmitted to the mounting frame 1 through the shock absorber 20, thereby improving the user experience.

[0113] In some embodiments, the angle block 3 and the rocker arm 5 are connected by a quick-release bolt, which can further improve the convenience of adjusting the height of the front frame, reduce the operation difficulty, and improve the user experience.

[0114] Referring to Figures 1 to 14 As shown, according to some embodiments of the present invention, the scooter includes a scooter frame, and the scooter frame is the above-mentioned scooter frame.

[0115] The above-mentioned scooter frame can be arranged on the front side of the scooter, or on the rear side of the scooter, or on both the front side and the rear side of the scooter, so as to facilitate adjusting the height of the front frame or the rear frame of the scooter according to needs, and meet the user's usage requirements.
