Description

Technical Field

[0001] This application relates to the field of transportation technology, and more particularly to a scooter. Background Technology

[0002] In related technologies, a scooter includes a frame, a front wheel assembly, and a rear wheel assembly. The frame has a footboard with a connecting arm at the front end. The front wheel assembly is mounted on the lower end of the connecting arm via a pivot. The rear end of the footboard has a rear wheel frame, and the rear wheel is mounted on the rear wheel frame. In this way, the user can stand on the footboard and ride by sliding the front wheel in the front wheel assembly and the rear wheel in the rear wheel assembly on the ground through manual or electric drive.

[0003] However, in related technologies, there are technical problems such as poor damping effect between the front wheel assembly and the connecting arm, and the damping stiffness is not adjustable. Utility Model Content

[0004] In view of the above problems, this application provides a scooter to improve the shock absorption effect of the scooter and make the shock absorption stiffness of the front wheel assembly adjustable. In this way, the user can adjust the shock absorption stiffness according to the needs, thereby improving the user's riding comfort.

[0005] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0006] This application provides a scooter, including:

[0007] A frame, the front end of which has a connecting arm;

[0008] A front wheel assembly, the front wheel assembly comprising a front wheel and a rocker arm;

[0009] The mounting sleeve is connected to one of the connecting arm and the rocker arm;

[0010] The first damping unit includes a first damping component and a bearing shaft. The bearing shaft passes through the mounting sleeve, and the first damping component is disposed between the peripheral wall of the bearing shaft and the inner wall of the mounting sleeve.

[0011] At least one second damping unit is disposed on at least one side of the connecting arm and is detachably connected to the load-bearing shaft and the connecting arm, respectively. Both the first damping unit and the second damping unit are configured to dampen the relative movement between the frame and the front wheel assembly.

[0012] The scooter provided in this application embodiment includes a frame, a front wheel assembly, a mounting sleeve, a first shock absorber unit, and at least one second shock absorber unit. The front end of the frame has a connecting arm. The front wheel assembly includes a front wheel and a rocker arm. The mounting sleeve is connected to one of the connecting arm and the rocker arm. The first shock absorber unit includes a first shock absorber and a load-bearing shaft. The load-bearing shaft passes through the mounting sleeve. The first shock absorber is disposed between the peripheral wall of the load-bearing shaft and the inner wall of the mounting sleeve. The second shock absorber unit is disposed on at least one side of the first shock absorber and is detachably connected to both the load-bearing shaft and the connecting arm. In this way, the first shock absorber unit can provide primary shock absorption for the movement between the frame and the front wheel assembly, while the second shock absorber unit can provide secondary shock absorption for the same movement, thereby improving the overall shock absorption effect of the scooter. In addition, the second shock absorber unit is detachably connected to the load-bearing axle and the connecting arm, allowing users to choose whether to add a second shock absorber unit or select a second shock absorber unit with a different shock absorption stiffness. This makes the overall shock absorption stiffness of the scooter adjustable to meet the needs of different users and thus improve the riding comfort.

[0013] In some embodiments, the second damping unit includes a fixing member and a second damping member. The second damping member surrounds the outer periphery of the bearing shaft and is detachably connected to the bearing shaft. The fixing member is located on the side of the second damping member opposite to the first damping member and is detachably connected to the connecting arm.

[0014] In this way, the second damping component is confined between the fixed component and the bearing shaft. When the rocker arm is subjected to an upward force, the second damping component deforms under the action of the bearing shaft and generates a reverse restoring force to achieve the effect of shock absorption, thereby improving the damping reliability and damping effect of the second damping component.

[0015] In some embodiments, the rocker arm includes a first sub-rocker arm along the axial direction of the bearing shaft, and the first sub-rocker arm and the second damping unit are respectively disposed on opposite sides of the first damping member.

[0016] In this way, while improving the shock absorption effect, the overall structure of the scooter is compact and easy to install and remove the second shock absorption unit, thereby improving the user experience.

[0017] In some embodiments, the rocker arm further includes a second sub-rocker arm located between the connecting arm and the fixing member, and the fixing member has a clearance notch at one end facing the second sub-rocker arm to avoid the second sub-rocker arm.

[0018] This improves the reliability and stability of the rocker arm's support for the front wheel assembly; in addition, it avoids interference between the second sub-rocker arm and the fixed component, thus ensuring the scooter's performance.

[0019] In some embodiments, when the scooter is stationary, the first shock absorber has a preload, while the second shock absorber does not.

[0020] In this way, when the scooter is in motion, the second shock absorber has a preload, which enables the first shock absorber to achieve primary shock absorption and the second shock absorber to achieve secondary shock absorption, thereby improving the overall shock absorption effect of the scooter and enhancing the user's riding comfort.

[0021] In some embodiments, the second damper has at least two damping portions arranged circumferentially along the bearing axis, and at least one of the inner wall of the mounting sleeve corresponding to the second damper and the fixing member has a mating portion that matches the at least two damping portions, wherein the at least two damping portions are configured to cooperate with the mating portion.

[0022] This can further improve the positional reliability and damping reliability of the second damping component, thereby improving the damping effect.

[0023] In some embodiments, at least two of the damping parts are connected in sequence to form an irregularly shaped sleeve hole, and the second damping member is sleeved on the bearing shaft through the sleeve hole.

[0024] In this way, the second damping component is directly fitted onto the bearing shaft, which improves the positional reliability and stability between the second damping component and the bearing shaft, while reducing the installation difficulty of the second damping component.

[0025] In some embodiments, at least two of the damping components are independent of each other and are arranged at intervals along the circumference of the bearing shaft. The bearing shaft has at least two mounting positions on its peripheral wall, and at least two of the damping components are respectively mounted on at least two mounting positions, wherein at least one of the damping components is provided on one mounting position.

[0026] In this way, the shock absorption stiffness of the scooter can be adjusted by increasing or decreasing the number of shock absorption parts in the second shock absorber to meet the different shock absorption stiffness requirements of users.

[0027] In some embodiments, at least a portion of the second shock absorber is located within the mounting sleeve; or,

[0028] The second shock absorber is located outside the mounting sleeve.

[0029] This increases the flexibility of the installation position of the second damping component, thereby improving the compactness of the structure.

[0030] In some embodiments, the second shock absorber is located inside the mounting sleeve, and the inner wall of the mounting sleeve corresponding to the second shock absorber has the mating portion;

[0031] The fastener is located outside the mounting sleeve and is detachably connected to the connecting arm.

[0032] In this way, the inner wall of the sleeve can limit the second damping component radially, and the fixing component and the first damping component can limit the second damping component axially, thereby improving the positional reliability of the second damping component.

[0033] In some embodiments, the second shock absorber is located inside the mounting sleeve, the fixing member is at least partially located inside the mounting sleeve and surrounds the outer periphery of the second shock absorber, and the fixing member has the mating portion.

[0034] This allows for further positioning of the second damping component, ensuring its accuracy and thus guaranteeing the damping effect.

[0035] In some embodiments, the second shock absorber is located outside the mounting sleeve, the fixing member surrounds the outer periphery of the second shock absorber, and the fixing member has the mating portion.

[0036] This makes it easier to install and remove the second shock absorber.

[0037] In some embodiments, the second shock absorber is located within the mounting sleeve, and both the inner wall of the mounting sleeve and the fixing member have the mating portion.

[0038] This facilitates the assembly and disassembly of the second shock absorber while improving its reliability and shock absorption effectiveness.

[0039] In some embodiments, the damping portion is a damping protrusion with a cross-section of at least one of a circle, an ellipse, a quadrilateral, and a polygon; the mating portion is a mating groove that matches the damping portion.

[0040] In this way, the structure of the shock-absorbing part and the mating part is simple, easy to implement, and low in cost.

[0041] In some embodiments, the second damping element is at least one of a rubber element, a silicone element, and a damping spring.

[0042] This ensures effective shock absorption while keeping costs low.

[0043] In some embodiments, a threaded connector is further included, through which the fixing member is detachably connected to the connecting arm; or...

[0044] It also includes a first magnetic component and a second magnetic component, the first magnetic component being disposed on the fixing component and the second magnetic component being disposed on the connecting arm, the first magnetic component and the second magnetic component being magnetically attracted to each other; or...

[0045] The fastener is provided with a first snap-fit ​​portion, and the connecting arm is provided with a second snap-fit ​​portion. The first snap-fit ​​portion is configured to snap-fit ​​with the second snap-fit ​​portion.

[0046] This reduces the difficulty of disassembling the fastener and connecting arm, making it easier for users to disassemble and thus improving the user experience.

[0047] In some embodiments, the first damping element is a damping cylinder, which is sleeved on the bearing shaft.

[0048] In this way, the first damping component is directly sleeved on the bearing shaft, which is a simple connection method and can achieve circumferential damping, thus improving the damping effect.

[0049] In some embodiments, the mounting sleeve is welded, threaded, or snap-fitted to one of the connecting arm and the rocker arm; or...

[0050] The mounting sleeve is an integral structure with one of the connecting arm and the rocker arm.

[0074] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0075] Figure 1 This is a schematic diagram of a scooter provided in an embodiment of this application. Please refer to... Figure 1 As shown, this application embodiment provides a scooter 10, wherein the scooter 10 can be an electric scooter with electric drive, or a human-powered scooter propelled by human force; as Figure 1 In this scooter 10, there is a frame 100, a front wheel assembly 200, and a rear wheel assembly 300. The frame 100 has a footboard 120, and the front end of the footboard 120 has a connecting arm 110. The front wheel assembly 200 includes a front wheel 210 and a rocker arm 220. The front wheel 210 is rotatably connected to the first end of the rocker arm 220 via an axle 211, and the second end of the rocker arm 220 is rotatably connected to the connecting arm 110. The rear wheel assembly 300 includes a rear wheel frame 320 and a rear wheel 310. The rear wheel frame 320 is mounted on the rear end of the footboard 120, and the rear wheel 310 is mounted on the rear wheel frame 320. In this way, the user can stand on the footboard 120 and ride by sliding the front wheel 210 and the rear wheel 310 on the ground through manual or electric drive.

[0076] When the scooter 10 is in motion, the front wheel 210 exerts an upward force on the rocker arm 220. The force on the rocker arm 220 is transmitted to the connecting arm 110, and then to the frame 100. The frame 100, through the connecting arm 110 and the rocker arm 220, exerts a reverse force on the axle 211 of the front wheel 210. As a result, there is a certain amount of vibration when the user is riding, especially on uneven roads, where the vibration will be greater, affecting the user's riding comfort. On the other hand, the stiffness of the frame 100 and the axle 211 of the front wheel 210 are fixed after manufacturing and cannot be adjusted. Therefore, when the vibration is large, it will affect the service life of the frame 100 and the axle 211 of the front wheel 210.

[0077] Based on the above problems, the scooter 10 provided in this application embodiment is equipped with a first shock absorption unit 400 and at least one second shock absorption unit 500, so that both the first shock absorption unit 400 and at least one second shock absorption unit 500 can absorb shocks for the scooter 10, thereby improving the shock absorption effect, improving the user's riding comfort and extending the service life of each component in the scooter 10.

[0078] The specific structure of the scooter 10 and various possible implementation methods will be described in detail below with reference to the accompanying drawings.

[0079] Figure 2 for Figure 1 A schematic diagram of an exploded structure; Figure 3 for Figure 2 A partial schematic diagram at point A in the middle; Figure 4 for Figure 1 Another schematic diagram of an explosive structure; Figure 5 for Figure 4 A partial schematic diagram at point B. Please refer to the diagram. Figures 2 to 5 As shown, the scooter 10 provided in this application embodiment also includes a mounting sleeve 111, which is connected to one of the connecting arm 110 and the rocker arm 220. In one example, the mounting sleeve 111 is connected to the connecting arm 110; in another example, the mounting sleeve 111 is connected to the rocker arm 220.

[0080] The mounting sleeve 111 can be welded to the connecting arm 110 and the rocker arm 220 to form an integral structure, or it can be detached by means of threaded connection, snap-fit, etc., so that when the mounting sleeve 111 is damaged, it can be disassembled and replaced.

[0081] Alternatively, the mounting sleeve 111 can also be integrally formed with one of the connecting arm 110 and the rocker arm 220 by means of casting or injection molding, for example, such as Figures 2 to 5 In the middle, the mounting sleeve 111 and the connecting arm 110 are an integral structure.

[0082] The following will take the connection between the mounting sleeve 111 and the connecting arm 110 as an example.

[0083] Please refer to Figures 2 to 5 , Figure 7 , Figure 8 As shown, the scooter 10 also includes a first shock-absorbing unit 400, which includes a first shock-absorbing component 410 and a bearing shaft 420. The bearing shaft 420 passes through the mounting sleeve 111. It is understood that the mounting sleeve 111 is a hollow structure, and the bearing shaft 420 passes through this hollow structure. The first end of the rocker arm 220 is rotatably connected to the axle 211 of the front wheel 210, and the second end of the rocker arm 220 is rotatably connected to the bearing shaft 420. The first shock-absorbing component 410 is disposed between the peripheral wall of the bearing shaft 420 and the inner wall of the mounting sleeve 111. The first shock-absorbing component 410 has a shock-absorbing function. For example, the first shock-absorbing component 410 includes, but is not limited to, a shock-absorbing cylinder made of elastic materials such as rubber or silicone. Figure 2 and Figure 3As shown, the first damping member 410 is a damping cylinder, which is sleeved on the bearing shaft 420. In addition, a fastening ring is also sleeved on the outer periphery of the first damping member 410. For example, the fastening ring is a rigid structure. In this way, the first damping member 410 is confined between the fastening ring and the peripheral wall of the bearing shaft 420. When installed in the mounting sleeve 111, the fastening ring is at least partially in direct contact with the inner wall of the mounting sleeve 111 so that the first damping member 410 has a preload.

[0084] Thus, when the scooter 10 is gliding, the front wheel 210 is subjected to an upward force, which drives the rocker arm 220 to rotate around the bearing shaft 420 and transmits the force to the bearing shaft 420. The first shock absorber 410 deforms under the force of the relative rotation between the bearing shaft 420 and the rocker arm 220. The first shock absorber 410 generates a first restoring force opposite to its deformation direction to counteract the force applied to the bearing shaft 420 by the rocker arm 220, so that the force on the bearing shaft 420 is not directly transmitted to the frame 100. That is, the first shock absorber 410 can absorb vibration, thereby avoiding rigid contact between the bearing shaft 420 and the frame 100 and generating large vibrations. It can be seen that by setting the first shock absorber 410 between the bearing shaft 420 and the inner wall of the mounting sleeve 111, a first-level shock absorption is formed, which improves the shock absorption effect of the scooter 10 and thus improves the riding comfort.

[0085] Please continue to refer to Figures 2 to 5 As shown, the scooter 10 also includes at least one second shock absorber unit 500. The at least one second shock absorber unit 500 is disposed on at least one side of the first shock absorber 410, and the second shock absorber unit 500 is detachably connected to the bearing shaft 420 and the connecting arm 110 respectively. In this way, when the scooter 10 is in motion, the front wheel 210 is subjected to an upward force, which drives the rocker arm 220 to move relative to the bearing shaft 420. After the bearing shaft 420 is subjected to the force of the rocker arm 220, both the first shock absorber 410 and the second shock absorber unit 500 are deformed. The first shock absorber 410 generates a first restoring force opposite to its deformation direction. At the same time, the second shock absorber unit 500 generates a second restoring force. Under the action of the first restoring force and the second restoring force, the rocker arm returns to its original position to form a two-stage shock absorption, which reduces the vibration between the front wheel assembly 200 and the frame 100, thereby further improving the shock absorption effect, improving the user's riding comfort, and extending the service life of the various components in the scooter 10.

[0086] In addition, the second shock absorber 500 is located on at least one side of the first shock absorber 410, and the second shock absorber 500 is detachably connected to the bearing shaft 420 and the connecting arm 110. In this way, the user can choose whether to add a second shock absorber 500, that is, the user can choose the secondary shock absorber, and thus can choose the shock absorption performance. In addition, the user can also choose the shock absorption stiffness of the second shock absorber according to specific needs, so that the overall stiffness of the scooter 10 is adjustable, improving the shock absorption effect while ensuring the overall stiffness of the scooter 10, which can extend the service life of the various parts of the scooter 10.

[0087] It is understandable that a second damping unit 500 is provided on either side or both sides of the first damping component 410, and the number of the second damping units 500 can be selected independently according to specific needs to meet the stiffness requirements and shock absorption effect of different scenarios, so as to further improve the user's riding comfort.

[0088] Please continue to refer to Figures 2 to 5 As shown, the second damping unit 500 includes a second damping member 510 and a fixing member 520. The second damping member 510 surrounds the outer periphery of the bearing shaft 420 and is detachably connected to the bearing shaft 420. The fixing member 520 is located on the side of the second damping member 510 away from the first damping member 410 and is detachably connected to the connecting arm 110. In this way, the fixing member 520 can limit and fix the second damping member 510 to improve the accuracy and reliability of the position of the second damping member 510.

[0089] For example, the second damping component 510 can be at least one of a rubber component, a silicone component, and a damping spring, thus ensuring the damping effect while keeping costs low.

[0090] When the scooter 10 is in motion, the front wheel 210 is subjected to an upward force, which causes the rocker arm 220 to move relative to the bearing shaft 420. After the bearing shaft 420 is subjected to the force of the rocker arm 220, it causes the first shock absorber 410 and the second shock absorber 510 to deform, thereby increasing the shock absorption rigidity. The first shock absorber 410 generates a first restoring force opposite to its deformation direction, and the second shock absorber 510 generates a second restoring force opposite to its deformation direction. The first and second restoring forces together drive the rocker arm 220 to return to its original position, thereby reducing vibration and improving riding comfort.

[0091] For example, the second damping member 510 may be made of elastic materials such as silicone or rubber, as long as it can achieve the shock absorption effect. In addition, the fixing member 520 may be a cover-shaped structure, so that when the second damping member 510 is coaxially connected with the bearing shaft 420, the fixing member 520 is disposed on the side of the second damping member 510 away from the first damping member 410 to limit and fix the second damping member 510.

[0092] In some embodiments, such as Figures 2 to 5 As shown, the first shock absorber 410 has a second shock absorber unit 500 on only one side. The rocker arm 220 includes a first sub-rocker arm 221. Along the axial direction of the bearing shaft 420, the first sub-rocker arm 221 is located on the side of the first shock absorber 410 away from the second shock absorber unit 500. That is, the first sub-rocker arm 221 and the second shock absorber unit 500 are respectively located on opposite sides of the first shock absorber. One end of the first sub-rocker arm 221 is rotatably connected to the axle 211 of the front wheel 210, and the other end is rotatably connected to the bearing shaft 420 to limit and support the front wheel 210. By placing the first sub-rocker arm 221 on the side of the first shock absorber 410 away from the second shock absorber unit 500, the first sub-rocker arm 221 can avoid affecting the disassembly and assembly of the second shock absorber unit 500, improve the convenience of disassembly and assembly of the second shock absorber unit 500, and also improve the structural compactness of the scooter 10.

[0093] In some other embodiments, the rocker arm 220 further includes a second sub-rocker arm. The second sub-rocker arm and the second damping unit 500 are disposed on the same side of the first damping member 410. That is, the first sub-rocker arm 221 and the second sub-rocker arm are respectively disposed on both sides of the first damping member 410. One end of the second sub-rocker arm is rotatably connected to the wheel axle 211 of the front wheel 210, and the other end is rotatably connected to the bearing shaft. In this way, the second sub-rocker arm and the first sub-rocker arm 221 together limit and support the front wheel 210, which can improve the stability and reliability of the front wheel 210.

[0094] For example, the second sub-rocker arm is located between the connecting arm 110 and the fixing member 520, and the end of the fixing member 520 facing the second sub-rocker arm has a clearance notch to avoid interference between the fixing member 520 and the second sub-rocker arm, which would affect the installation of the second shock absorption unit 500, thereby avoiding affecting the shock absorption effect and overall performance of the scooter 10.

[0095] It should be noted that when the scooter 10 is equipped with the first shock-absorbing unit and the second shock-absorbing unit, when the scooter is stationary, the first shock-absorbing component 410 has a preload, while the second shock-absorbing component 510 does not. When the scooter 10 is in motion, both the first shock-absorbing component 410 and the second shock-absorbing component 510 have a preload to reduce the vibration of the scooter 10, thereby improving the shock absorption effect and enhancing the user's riding comfort.

[0096] In some embodiments, the second damper 510 has at least two damping portions 511 arranged circumferentially along the bearing shaft 420. The mounting sleeve 111 has a corresponding inner wall of the cylinder and at least one of the fixing member 520, which has a mating portion that matches the at least two damping portions 511. The at least two damping portions 511 are configured to cooperate with the mating portion. In this way, the damping stiffness of the second damper 510 can be determined by increasing or decreasing the number of damping portions 511. In addition, by cooperating with the corresponding damping portions 511 through the mating portion, the positional reliability and damping reliability of the second damper can be further improved, thereby improving the damping effect.

[0097] Please refer to Figure 2 and Figure 3 As shown, at least two damping parts 511 are connected in sequence, jointly forming an anisotropic socket 512. The second damping member 510 is sleeved on the bearing shaft 420 through the socket 512. To enable the second damping member 510 to rotate coaxially with the bearing shaft 420, the cross-sectional shape of the bearing shaft 420 is polygonal. Correspondingly, the outline shape of the socket 512 on the second damping member 510 matches the polygonal shape of the bearing shaft 420. In this way, when the second damping member 510 is sleeved on the bearing shaft 420, it can drive the second damping member 510 to rotate coaxially. For example, in Figure 2 and Figure 3 As shown, the socket 512 is a quadrilateral hole, and the cross-sectional profile of the bearing shaft 420 is also a matching quadrilateral.

[0098] For example, in Figure 2 and Figure 3 In this process, at least two shock-absorbing parts 511 are connected in sequence to form a shock-absorbing block or other structure with a socket 512. As long as the second shock-absorbing part 510 has no pre-tightening force when the scooter 10 is stationary, and the second shock-absorbing part 510 can generate an elastic pre-tightening force with torsional force when sliding, so as to achieve the purpose of shock absorption, no specific restrictions are made here.

[0099] It is understandable that the number of shock absorbers 511 can be adapted to specific needs and no specific restrictions are imposed here.

[0100] In one example, at least two shock absorber parts 511 may be formed into an integral structure by means of injection molding or the like; in another example, at least two shock absorber parts 511 may also be detachable, so that users can choose the number of shock absorber parts 511 to meet different shock absorption needs and improve riding comfort.

[0101] For example, at least two shock absorbers 511 may be detachably connected by means of snap-fit, magnetic attraction, etc.

[0102] In other embodiments, please refer to Figure 7 and Figure 8 As shown, at least two shock absorbers 511 are independent of each other and are arranged at intervals along the circumference of the bearing shaft 420. In this way, the user can adjust the shock absorption stiffness of the scooter 10 by increasing or decreasing the number of shock absorbers 511 to meet the user's different shock absorption stiffness requirements.

[0103] In addition, to improve the positional reliability of at least two damping components 511 on the bearing shaft 420 circumference, such as Figure 7 and Figure 8 The peripheral wall of the bearing shaft 420 has at least two mounting positions 421. The outline of the mounting position 421 matches the outline of the damping part 511. The at least two mounting positions 421 are arranged at intervals along the circumference of the bearing shaft 420. The at least two damping parts 511 are respectively mounted on the at least two mounting positions 421. At least one damping part 511 is provided on each mounting position 421. In this way, the damping parts 511 are mounted on the corresponding mounting positions 421, which can improve the accuracy and reliability of the position of each damping part 511 in the circumferential direction of the bearing shaft 420, thereby improving the damping reliability of the second damping member 510 and ensuring the damping effect.

[0104] The damping part 511 includes, but is not limited to, a columnar structure with a cross-section of at least one of a circle, an ellipse, or a polygon. Thus, the structure of the damping part 511 is simple, easy to implement, and low in cost.

[0105] For example, such as Figure 7 and Figure 8 As shown, the damping part 511 is a cylinder with a circular cross-section, and there are 4 damping parts 511. Correspondingly, the mounting position 421 is an arc-shaped groove structure that matches the outer contour of the damping part 511. There are also 4 mounting positions 421. During installation, the damping part 511 is installed on the corresponding mounting position 421 to improve the positional reliability of the damping part 511, thereby improving the damping reliability and ensuring the damping effect.

[0106] It should be noted that the number of shock absorbers 511 can be 1, 2, 3, 4 or more. The number can be increased or decreased according to actual needs, as long as the shock absorption effect and the overall rigidity of the scooter are met. No specific restrictions are imposed here.

[0107] For example, the shock-absorbing part 511 can be at least one of a rubber part, a silicone part, and a shock-absorbing spring with a circular or other arbitrary cross-section, so as to ensure the shock absorption effect while keeping the cost low.

[0108] In addition, in some embodiments, at least a portion of the second damping member 510 may be located inside the mounting sleeve 111, that is, the second damping member 510 may be entirely located inside the mounting sleeve 111 or partially located inside the mounting sleeve 111; or, the second damping member 510 may be entirely located outside the mounting sleeve 111. This can improve the flexibility of the placement of the second damping member 510, improve space utilization, and thus improve the overall structural compactness.

[0109] For example, the entire structure of the second damper 510 is located inside the mounting sleeve 111. The inner wall of the mounting sleeve 111 corresponding to the second damper 510 has a mating part, wherein the mating part matches the contour of the second damper 510. For example, if the second damper 510 includes at least two damping parts 511 along the circumferential direction, then the contour shape of the mating part matches the contour of the corresponding damping part 511. In this way, the mating part and the second damper 510 cooperate to improve the positional reliability of the second damper 510. In addition, the fixing member 520 is located outside the mounting sleeve 111 and is detachably connected to the connecting arm 110. That is, the fixing member 520 limits and fixes the end of the second damper 510 to prevent the second damper 510 from moving in its axial direction, so as to further improve the positional accuracy and reliability of the second damper 510, thereby ensuring the damping effect.

[0110] In another example, the second shock absorber 510 is located inside the mounting sleeve 111, and the fixing member 520 is at least partially located inside the mounting sleeve 111 and surrounds the outer periphery of the second shock absorber 510. The fixing member 520 has a mating part that matches the outer contour of the second shock absorber 510, such as a mating groove. In this way, the fixing member 520 limits and fixes the second shock absorber 510 in the circumferential and axial directions, and the fixing member 520 is detachably connected to the connecting arm 110. For example, the fixing member 520 and the connecting arm 110 can be detachably connected by elastic snap-fit, mechanical snap-fit, magnetic attraction, etc. In this way, the overall structure of the scooter 10 can be improved in terms of compactness.

[0111] Another example, such as Figures 2 to 5 , Figure 7 as well as Figure 8 As shown, the second damping member 510 is located outside the mounting sleeve 111, and the fixing member 520 surrounds the outer periphery of the second damping member 510. The fixing member 520 has a mating part, for example, as shown in the figure. Figure 6 and Figure 8As shown, the mating part is a mating groove 521 corresponding to the damping part 511. In this way, when the fixing member 520 surrounds the outer periphery of the second damping member 510 and is detachably connected to the connecting arm 110, each damping part 511 in the second damping member 510 is located in the corresponding mating groove 521 to limit and fix the damping part 511, improve the positional reliability of the damping part 511, thereby improving the damping reliability and ensuring the damping effect.

[0112] In some other embodiments, the second shock absorber 510 is partially located inside the mounting sleeve 111. The hole wall of the mounting sleeve 111 and the fixing member 520 both have mating parts. That is, the second shock absorber 510 and the fixing member 520 are partially located inside the mounting sleeve 111 and partially located outside the mounting sleeve 111. The fixing member 520 is detachably connected to the connecting arm 110. In this way, the second shock absorber 510 can be easily disassembled and assembled, while the compactness of the structure can be improved.

[0113] like Figures 2 to 6 As shown, the damping part 511 is a damping protrusion with a cross-section of at least one of a circle, an ellipse, a quadrilateral, and a polygon, and the mating part is a mating groove that matches the damping protrusion; or, as... Figure 7 and Figure 8 As shown, the damping part 511 is an independent damping column with a cross-section of at least one of circular, elliptical, quadrilateral and polygonal shapes, and the mating part matches the outline shape of the damping column.

[0114] In some embodiments, such as Figure 4 and Figure 5 As shown, the first damping component 410 and the second damping component 510 are sequentially sleeved on the bearing shaft 420, with the first damping component 410 located inside the mounting sleeve 111 and the second damping component 510 located outside the mounting sleeve 111. The fixing component 520 is disposed on the outer periphery of the second damping component 510 and connected to the connecting arm 110 through the threaded connector 600. In this way, when the second damping component 510 needs to be disassembled, only the threaded connector 600 needs to be removed to remove the second damping component 510 from the bearing shaft 420, which improves the ease of disassembly and assembly of the second damping component 510, thereby allowing users to choose whether to add a second damping component 510 to achieve different damping effects.

[0115] In other embodiments, the fixing member 520 and the connecting arm 110 can also be detachably connected by magnetic adsorption through the first magnetic member and the second magnetic member. Specifically, the fixing member 520 is fixedly provided with the first magnetic member, and the connecting arm 110 is fixedly provided with the second magnetic member. In this way, when the fixing member 520 moves toward the connecting arm 110, the first magnetic member and the second magnetic member magnetically attract each other, thereby completing the installation. When disassembling, it is only necessary to apply a force greater than the magnetic adsorption to the fixing member 520 to remove it. The disassembly and assembly are simple and do not require other disassembly and assembly tools, thereby reducing the disassembly and assembly costs.

[0116] In some other embodiments, the fastener 520 and the connecting arm 110 can also be detachably connected by a snap-fit ​​mechanism. For example, the fastener 520 is provided with a first snap-fit ​​portion, and the connecting arm 110 is provided with a second snap-fit ​​portion. The first snap-fit ​​portion and the second snap-fit ​​portion can snap-fit ​​or de-snap, thereby achieving a detachable connection, and the disassembly method is simple. For example, the first snap-fit ​​portion is one of a snap-fit ​​protrusion and a snap-fit ​​groove, and the second snap-fit ​​portion is the other of a snap-fit ​​protrusion and a snap-fit ​​groove.

[0117] Please continue to refer to Figure 2 , Figure 3 as well as Figure 7 and Figure 8 As shown, the scooter 10 also includes a bearing 230, an end cap 240, a fastener 260, a nut 270, and a decorative piece 250. The end cap 240 is mounted on the bearing shaft 420 via the bearing 230 and is fixedly connected to the connecting arm 110 via the fastener 260. The rocker arm 220 passes through the bearing shaft 420 and is located on the side of the end cap 240 away from the connecting arm 110. The bearing shaft 420 has an external thread near its end, and the nut 270 is threaded to the external thread to limit and fix the rocker arm 220 in the axial direction of the bearing shaft 420. In addition, the decorative piece 250 is located on the side of the rocker arm 220 away from the connecting arm 110. The decorative piece 250 can be fastened to the outer periphery of the rocker arm 220 by snap-fit ​​or other means. The color and other aspects of the decorative piece 250 match the scooter 10 to enhance the aesthetics of the scooter 10 and also to protect the rocker arm 220.

[0118] In some embodiments, the bearing shaft 420 includes at least a first sub-bearing shaft and a second sub-bearing shaft, a first damping member 410 is sleeved on the first sub-bearing shaft, and a second damping member 510 is sleeved on the second sub-bearing shaft. For example, when the first damping member 410 is a damping cylinder, the radial dimension (or cross-sectional dimension, i.e., the dimension perpendicular to the axial direction) of the first sub-bearing shaft matches the cross-sectional dimension of the inner hole of the damping cylinder, while the radial dimension (or cross-sectional dimension) of the second sub-bearing shaft matches the cross-sectional dimension of the sleeve hole 512 of the second damping member 510.

[0119] The first and second sub-bearing shafts can be integral structures formed by casting, injection molding, or machining; alternatively, they can be independent of each other. Furthermore, regardless of whether they are integral or independent, they can be coaxial or non-coaxial. When they are independent, they can be detachably connected (e.g., snap-fit, magnetic attraction), fixedly connected (e.g., adhesive bonding, welding), or not connected at all. The specific design can be tailored to the actual situation, and no specific restrictions are imposed here.

[0120] For example, such as Figures 2 to 5 , Figure 7 and Figure 8 As shown, the bearing shaft 420 is a stepped shaft with a coaxial and integral structure.

[0121] In summary, the scooter provided in this application includes a frame, a front wheel assembly, a mounting sleeve, a first shock absorber, and at least one second shock absorber. The front end of the frame has a connecting arm; the front wheel assembly includes a front wheel and a rocker arm; the mounting sleeve is connected to one of the connecting arm and the rocker arm; the first shock absorber includes a first shock absorber and a bearing axle, the bearing axle passing through the mounting sleeve, the first shock absorber being disposed between the peripheral wall of the bearing axle and the inner wall of the mounting sleeve, and the second shock absorber being disposed on at least one side of the first shock absorber and detachably connected to both the bearing axle and the connecting arm. In this way, the first shock absorber unit can provide primary shock absorption for the movement between the frame and the front wheel assembly, while the second shock absorber unit can provide secondary shock absorption for the same movement, thereby improving the overall shock absorption effect of the scooter. In addition, the second shock absorber unit is detachably connected to the load-bearing axle and the connecting arm, allowing users to choose whether to add a second shock absorber unit or select a second shock absorber unit with a different shock absorption stiffness. This makes the overall shock absorption stiffness of the scooter adjustable to meet the needs of different users and thus improve the riding comfort.
