[0013] In some embodiments, the second shock absorbing unit includes a fixing member and a second shock absorbing member, the second shock absorbing member is arranged around the outer periphery of the load-bearing shaft and is detachably connected to the load-bearing shaft, and the fixing member is located on a side of the second shock absorbing member away from the first shock absorbing member and is detachably connected to the connecting arm.

[0014] In this way, the second shock absorber is limited between the fixing member and the load-bearing shaft. When the rocker arm is subjected to an upward force, the second shock absorber is deformed under the action of the load-bearing shaft, and the second shock absorber generates a reverse restoring force to achieve a shock-absorbing effect, thereby improving the shock-absorbing reliability and shock-absorbing effect of the second shock absorber.

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

[0019] In some embodiments, when the scooter is in a stationary state, the first shock absorber has a pre-tension force, and the second shock absorber does not have a pre-tension force.

[0020] In this way, when the scooter is moving, the second shock absorber has a pre-tension force, so that the first shock absorber realizes primary shock absorption, and the second shock absorber realizes secondary shock absorption, thereby improving the overall shock absorption effect of the scooter and enhancing the riding comfort of the user.

There are at least two mounting positions on the circumferential wall of the bearing shaft, and at least two of the shock-absorbing portions are respectively mounted on at least two of the mounting positions, wherein at least one of the shock-absorbing portions is correspondingly arranged on one of the mounting positions.

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

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

[0029] In this way, the flexibility of the installation position of the second shock absorber is improved to enhance the compactness of the structure.

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

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

[0034] In this way, the second shock-absorbing member can be further limited, the position accuracy of the second shock-absorbing member can be ensured, and thus the shock-absorbing effect can be ensured.

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

[0036] In this way, it is convenient to disassemble and assemble the second shock-absorbing member.

[0037] In some embodiments, part of the second shock-absorbing member is located inside the mounting sleeve, and both the inner wall of the sleeve of the mounting sleeve and the fixing member have the engaging portion.

[0038] In this way, while facilitating the disassembly and assembly of the second shock-absorbing member, the reliability of the second shock-absorbing member and the effectiveness of shock absorption can be improved.

[0040] In this way, the structures of the shock-absorbing portion and the engaging portion are simple, easy to implement, and low in cost.

[0041] In some embodiments, the second shock-absorbing member is at least one of a rubber member, a silica gel member, and a shock-absorbing spring.

[0042] In this way, while ensuring the shock-absorbing effect, the cost is low.

[0074] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0075] Figure 1 This is a schematic structural diagram of a scooter provided by an embodiment of this application. Please refer to Figure 1 As shown, an embodiment of this application provides a scooter 10. Among them, the scooter 10 can be an electric scooter with electric drive or a manual scooter that is slid by human power; as Figure 1 shown in the figure, the scooter 10 includes a frame 100, a front wheel set 200, and a rear wheel set 300. The frame 100 has a pedal 120, and the front end of the pedal 120 has a connecting arm 110. The front wheel set 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 through a wheel axle 211, and the second end of the rocker arm 220 is rotatably connected to the connecting arm 110. The rear wheel set 300 includes a rear wheel frame 320 and a rear wheel 310. The rear wheel frame 320 is installed at the rear end of the pedal 120, and the rear wheel 310 is installed on the rear wheel frame 320. In this way, the user can stand on the pedal 120 and, through a sliding method driven by human power or electricity, make the front wheel 210 and the rear wheel 310 roll on the ground to achieve riding.

[0076] When the scooter 10 is traveling, the front wheel 210 will apply an upward force to the rocker arm 220, and the force received by the rocker arm 220 is transmitted to the connecting arm 110, and then transmitted to the frame 100. The frame 100 will give a reverse force to the wheel axle 211 of the front wheel 210 through the connecting arm 110 and the rocker arm 220. In this way, when the user is riding, there is a certain amount of vibration, especially when the road surface is uneven, the generated vibration will be greater, affecting the riding comfort of the user. On the other hand, the stiffness of components such as the frame 100 and the wheel axle 211 of the front wheel 210 is determined after manufacturing and the stiffness is not adjustable. In this way, when the vibration is large, it will affect the service life of components such as the frame 100 and the wheel axle 211 of the front wheel 210.

[0077] Based on the above problems, in the scooter 10 provided by the embodiments of this application, by providing a first shock absorption unit 400 and at least one second shock absorption unit 500, both the first shock absorption unit 400 and at least one second shock absorption unit 500 shock-absorb the scooter 10, improving the shock absorption effect, thereby improving the riding comfort of the user and extending the service life of each component in the scooter 10.

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

[0079] Figure 2 For Figure 1 a schematic explosion structure diagram of Figure 3 For Figure 2 a partial schematic diagram at position A in Figure 4 For Figure 1 another schematic explosion structure diagram of Figure 5 For Figure 4 a partial schematic diagram at position B in Figures 2 to 5 As shown in

[0080] The scooter 10 provided in the embodiment of the present application further includes a mounting sleeve 111. The mounting sleeve 111 is connected to one of the connecting arm 110 and the rocker arm 220. Exemplarily, the mounting sleeve 111 is connected to the connecting arm 110; alternatively, the mounting sleeve 111 is connected to the rocker arm 220.

[0081] Wherein, the mounting sleeve 111 and one of the connecting arm 110 and the rocker arm 220 can be integrally formed by welding, or can also be detachably connected by means of threaded connection, clamping, etc. In this way, when the mounting sleeve 111 is damaged, it can be disassembled and replaced. Figures 2 to 5 Or, 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. Exemplarily, as in

[0082] The mounting sleeve 111 and the connecting arm 110 are integrally formed.

[0083] Please refer to Figures 2 to 5 , Figure 7 , Figure 8 As shown in Figure 2 and Figure 3 The scooter 10 further includes a first shock absorption unit 400. The first shock absorption unit 400 includes a first shock absorber 410 and a bearing shaft 420. The bearing shaft 420 passes through the mounting sleeve 111. It can be understood that the mounting sleeve 111 is a hollow structure, and the bearing shaft 420 passes through the 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 absorber 410 is disposed between the peripheral wall of the bearing shaft 420 and the inner wall of the barrel of the mounting sleeve 111. Among them, the first shock absorber 410 has a shock absorption function. For example, the first shock absorber 410 includes, but is not limited to, a shock absorption cylinder and other structures made of elastic materials such as rubber and silica gel, as inAs shown, the first shock absorber 410 is a shock absorber cylinder, which is sleeved on the bearing shaft 420. In addition, a fastening ring is sleeved on the outer periphery of the first shock absorber 410. For example, the fastening ring is a rigid structure. In this way, the first shock absorber 410 is restricted between the fastening ring and the peripheral wall of the bearing shaft 420. When installed in the mounting sleeve 111, at least part of the fastening ring is in direct contact with the inner wall of the mounting sleeve 111, so that the first shock absorber 410 has a pre-tightening force.

[0084] In this way, when the scooter 10 is sliding, after the front wheel 210 receives an upward force, it 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 acting force of 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 exerted by the rocker arm 220 on the bearing shaft 420, so that the force received by the bearing shaft 420 is not directly transmitted to the vehicle frame 100. That is, the first shock absorber 410 can absorb vibrations, thereby avoiding rigid contact between the bearing shaft 420 and the vehicle frame 100 and generating large vibrations. It can be seen that by arranging the first shock absorber 410 between the bearing shaft 420 and the inner wall of the mounting sleeve 111 to form a primary shock absorption, the shock absorption effect of the scooter 10 is improved, thereby improving the riding comfort.

[0085] Please continue to refer to Figures 2 to 5 As shown, the scooter 10 further includes at least one second shock absorption unit 500. At least one second shock absorption unit 500 is arranged on at least one side of the first shock absorber 410, and the second shock absorption unit 500 is detachably connected to the bearing shaft 420 and the connecting arm 110 respectively. In this way, when the scooter 10 is moving, after the front wheel 210 receives an upward force, it drives the rocker arm 220 to move relative to the bearing shaft 420. After the bearing shaft 420 receives the force from the rocker arm 220, both the first shock absorber 410 and the second shock absorption unit 500 deform. The first shock absorber 410 generates a first restoring force opposite to its deformation direction. At the same time, the second shock absorption 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 secondary shock absorption, reducing the vibration between the front wheel group 200 and the vehicle frame 100, thereby further improving the shock absorption effect, improving the riding comfort of the user, and prolonging the service life of each component in the scooter 10.

[0086] In addition, the second shock absorbing unit 500 is located on at least one side of the first shock absorbing member 410, and the second shock absorbing unit 500 is detachably connected to the bearing shaft 420 and the connecting arm 110, so that the user can independently choose whether to add the second shock absorbing unit 500, that is, the secondary shock absorbing user can independently choose, so that the shock absorbing performance can be independently selected. In addition, the user can also independently select the shock absorbing stiffness of the second shock absorbing unit according to specific needs, so that the overall stiffness of the scooter 10 is adjustable, and the shock absorbing effect is improved while ensuring the overall stiffness of the scooter 10, which can extend the service life of various components of the scooter 10.

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

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

[0089] Exemplarily, the second shock absorbing member 510 may be at least one of a rubber member, a silicone member and a shock absorbing spring, so that the shock absorbing effect is ensured while the cost is low.

[0090] When the scooter 10 is running, 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, the first shock absorber 410 and the second shock absorber 510 are deformed to increase the shock absorbing rigidity. The first shock absorber 410 generates a first restoring force in the opposite direction of its deformation, and the second shock absorber 510 generates a second restoring force in the opposite direction of its deformation. The first restoring force and the second restoring force jointly drive the rocker arm 220 to return to its original position, thereby reducing vibration and improving riding comfort.

[0091] Exemplarily, the second shock absorber 510 includes but is not limited to being made of elastic materials such as silicone, rubber, etc., as long as the shock absorption effect can be achieved. In addition, the fixing member 520 is, for example, a cover-like structure. In this way, when the second shock absorber 510 is coaxially connected to the load-bearing shaft 420, the fixing member 520 is arranged on the side of the second shock absorber 510 away from the first shock absorber 410 to limit and fix the second shock absorber 510.

[0092] In some embodiments, as Figures 2 to 5 shown in the figure, the second damping unit 500 is provided only on one side of the first damping member 410. 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 disposed on the side of the first damping member 410 away from the second damping unit 500, that is, the first sub-rocker arm 221 and the second damping unit 500 are respectively disposed on opposite sides of the first damping member. Wherein, 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. And disposing the first sub-rocker arm 221 on the side of the first damping member 410 away from the second damping unit 500 can prevent the first sub-rocker arm 221 from affecting the disassembly and assembly of the second damping unit 500, improve the convenience of disassembly and assembly of the second damping unit 500, and also improve the structural compactness of the scooter 10.

[0093] In 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. And one end of the second sub-rocker arm is rotatably connected to the 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 jointly limit and support the front wheel 210, which can improve the stability and reliability of the front wheel 210.

[0094] Exemplarily, the second sub-rocker arm is located between the connecting arm 110 and the fixing member 520, and one end of the fixing member 520 facing the second sub-rocker arm has an avoidance notch for avoiding the second sub-rocker arm, so as to prevent interference between the fixing member 520 and the second sub-rocker arm and affect the installation of the second damping unit 500, thereby avoiding affecting the damping effect and overall performance of the scooter 10.

[0095] It should be noted that when the first damping unit and the second damping unit are installed on the scooter 10, when the scooter is in a stationary state, the first damping member 410 has a pre-tightening force, and the second damping member 510 does not have a pre-tightening force; when the scooter 10 is in motion, both the first damping member 410 and the second damping member 510 have a pre-tightening force to reduce the vibration of the scooter 10, thereby improving the damping effect and the riding comfort of the user.

[0096] In some embodiments, the second shock absorber 510 has at least two shock-absorbing portions 511. The at least two shock-absorbing portions 511 are arranged circumferentially along the load-bearing shaft 420. At least one of the inner cylindrical wall of the mounting sleeve 111 corresponding to the second shock absorber 510 and the fixing member 520 has a mating portion that matches the at least two shock-absorbing portions 511. The at least two shock-absorbing portions 511 are configured to cooperate with the mating portion. In this way, the shock-absorbing stiffness of the second shock absorber 510 can be determined by increasing or decreasing the number of shock-absorbing portions 511. In addition, by the cooperation between the mating portion and the corresponding shock-absorbing portion 511, the position reliability and shock-absorbing reliability of the second shock absorber 510 can be further improved, thereby enhancing the shock-absorbing effect.

[0097] Please refer to Figure 2 and Figure 3 As shown, the at least two shock-absorbing portions 511 are sequentially connected and jointly enclose an irregular socket hole 512. The second shock absorber 510 is sleeved on the load-bearing shaft 420 through the socket hole 512. In order to enable the second shock absorber 510 to rotate coaxially with the load-bearing shaft 420, the cross-sectional shape of the load-bearing shaft 420 is polygonal. Correspondingly, the contour shape of the socket hole 512 on the second shock absorber 510 is a polygon that matches the load-bearing shaft 420. In this way, when the second shock absorber 510 is sleeved on the load-bearing shaft 420, it can drive the second shock absorber 510 to rotate coaxially. For example, in Figure 2 and Figure 3 as shown, the socket hole 512 is a quadrilateral hole, and the cross-sectional contour of the load-bearing shaft 420 is also a quadrilateral that matches it.

[0098] Exemplarily, in Figure 2 and Figure 3 at least two shock-absorbing portions 511 are sequentially connected to form a structure such as a shock-absorbing block with a socket hole 512. As long as the second shock absorber 510 has no pre-tightening force when the scooter 10 is stationary and can generate an elastic pre-tightening force with a torsional force when sliding to achieve the purpose of shock absorption, specific limitations are not made here.

[0099] It can be understood that the number of shock-absorbing portions 511 can be adaptively designed according to specific requirements, and specific limitations are not made here.

[0100] Among them, exemplarily, at least two shock-absorbing portions 511 can be formed into an integral structure by injection molding or the like; alternatively, at least two shock-absorbing portions 511 can also be detachable. In this way, the user can independently select the number of shock-absorbing portions 511, thereby meeting different shock-absorbing requirements and improving riding comfort.

[0101] For example, the at least two shock-absorbing portions 511 include but are not limited to being detachably connected by means such as snap connection and magnetic attraction.

[0102] In some other embodiments, please refer to Figure 7 and Figure 8 As shown, at least two shock-absorbing parts 511 are independent of each other and are arranged at intervals along the circumferential direction of the bearing shaft 420. In this way, the user can independently adjust the number of shock-absorbing parts 511 to adjust the shock-absorbing stiffness of the scooter 10 to meet the different shock-absorbing stiffness requirements of the user.

[0103] In addition, in order to improve the position reliability of at least two shock-absorbing parts 511 on the circumference of the bearing shaft 420, as Figure 7 and Figure 8 shown, the circumferential wall of the bearing shaft 420 has at least two mounting positions 421. The contour of the mounting position 421 matches the contour of the shock-absorbing part 511. At least two mounting positions 421 are arranged at intervals along the circumferential direction of the bearing shaft 420. At least two shock-absorbing parts 511 are respectively mounted on at least two mounting positions 421. Among them, at least one shock-absorbing part 511 is correspondingly arranged on one mounting position 421. In this way, the shock-absorbing part 511 is mounted on the corresponding mounting position 421, which can improve the accuracy and reliability of the position of each shock-absorbing part 511 in the circumferential direction of the bearing shaft 420, thereby improving the shock-absorbing reliability of the second shock-absorbing member 510 and ensuring the shock-absorbing effect.

[0104] Among them, the shock-absorbing 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. In this way, the structure of the shock-absorbing part 511 is simple, easy to implement and has a low cost.

[0105] Exemplarily, as Figure 7 and Figure 8 shown, the shock-absorbing part 511 is a cylinder with a circular cross-section, and the number of shock-absorbing parts 511 is 4. Correspondingly, the mounting position 421 is an arc-shaped groove structure that matches the outer contour of the shock-absorbing part 511, and the number of mounting positions 421 is also 4. During installation, the shock-absorbing part 511 is mounted on the corresponding mounting position 421 to improve the position reliability of the shock-absorbing part 511, thereby improving the shock-absorbing reliability and ensuring the shock-absorbing effect.

[0106] It should be noted that the number of shock-absorbing parts 511 can be 1, 2, 3, 4 or more than 4, and can be increased or decreased according to actual needs, as long as the shock-absorbing effect can be satisfied and the overall stiffness of the scooter can be ensured. No specific limitation is made here.

[0107] Exemplarily, the shock-absorbing part 511 can be at least one of a rubber part, a silica gel part and a shock-absorbing spring with a circular cross-section or any other shape, so that while ensuring the shock-absorbing effect, the cost is low.

[0108] In addition, in some embodiments, at least a part of the second shock absorber 510 may be located inside the mounting sleeve 111, that is, the second shock absorber 510 may be entirely located inside the mounting sleeve 111 or partially located inside the mounting sleeve 111; alternatively, the second shock absorber 510 is entirely located outside the mounting sleeve 111. In this way, the flexibility of the setting position of the second shock absorber 510 can be improved, the space utilization rate can be increased, and thus the overall structural compactness can be improved.

[0109] Exemplarily, the entire structure of the second shock absorber 510 is located inside the mounting sleeve 111. The inner wall of the mounting sleeve 111 corresponding to the second shock absorber 510 has a mating portion, where the mating portion matches the corresponding contour of the second shock absorber 510. For example, if the second shock absorber 510 includes at least two shock-absorbing portions 511 circumferentially distributed, the contour shape of the mating portion matches the contour of the corresponding shock-absorbing portion 511. In this way, the mating of the mating portion and the second shock absorber 510 can improve the position reliability of the second shock absorber 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 shock absorber 510 to prevent the second shock absorber 510 from moving axially, so as to further improve the position accuracy and reliability of the second shock absorber 510, thereby ensuring the shock-absorbing effect.

[0110] Another exemplarily, 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 portion that matches the outer contour of the second shock absorber 510. The mating portion is, for example, a mating groove. In this way, the fixing member 520 limits and fixes the second shock absorber 510 both circumferentially and axially, 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 clamping, mechanical clamping, magnetic attraction, etc. In this way, the overall structural compactness of the scooter 10 can be improved.

[0111] Another exemplarily, as Figures 2 to 5 、 Figure 7 and Figure 8 shown, the second shock absorber 510 is located outside the mounting sleeve 111, the fixing member 520 surrounds the outer periphery of the second shock absorber 510, and the fixing member 520 has a mating portion. Exemplarily, as Figure 6 and Figure 8As shown, the mating portion is a mating groove 521 corresponding to the shock-absorbing portion 511. In this way, when the fixing member 520 is disposed around the outer periphery of the second shock-absorbing member 510 and is detachably connected to the connecting arm 110, each shock-absorbing portion 511 in the second shock-absorbing member 510 is respectively located in the corresponding mating groove 521 to limit and fix the shock-absorbing portion 511, improve the position reliability of the shock-absorbing portion 511, thereby improving the shock-absorbing reliability and ensuring the shock-absorbing effect.

[0112] In some other embodiments, a part of the second shock-absorbing member 510 is located inside the mounting sleeve 111. Both the hole wall of the mounting sleeve 111 and the fixing member 520 have mating portions. That is to say, a part of the second shock-absorbing member 510 and the fixing member 520 are located inside the mounting sleeve 111, and a part is located outside the mounting sleeve 111, and the fixing member 520 is detachably connected to the connecting arm 110. In this way, while facilitating the disassembly and assembly of the second shock-absorbing member 510, the compactness of the structure can be improved.

[0113] As Figures 2 to 6 shown, the shock-absorbing portion 511 is a shock-absorbing protrusion with a cross-section being at least one of a circle, an ellipse, a quadrilateral, and a polygon, and the mating portion is a mating groove matching the shock-absorbing protrusion; or, as Figure 7 and Figure 8 shown, the shock-absorbing portion 511 is an independent shock-absorbing column with a cross-section being at least one of a circle, an ellipse, a quadrilateral, and a polygon. Correspondingly, the mating portion matches the contour shape of the shock-absorbing column.

[0114] In some embodiments, as Figure 4 and Figure 5 shown, the first shock-absorbing member 410 and the second shock-absorbing member 510 are sequentially sleeved on the bearing shaft 420. The first shock-absorbing member 410 is located inside the mounting sleeve 111, and the second shock-absorbing member 510 is located outside the mounting sleeve 111. The fixing member 520 is disposed on the outer periphery of the second shock-absorbing member 510 and is connected to the connecting arm 110 through a threaded connector 600. In this way, when it is necessary to disassemble the second shock-absorbing member 510, only the threaded connector 600 needs to be removed, and the second shock-absorbing member 510 can be disassembled from the bearing shaft 420, improving the disassembly and assembly convenience of the second shock-absorbing member 510, thereby facilitating the user to independently choose whether to add the second shock-absorbing member 510 to achieve different shock-absorbing effects.

[0115] In some other embodiments, the fixing member 520 and the connecting arm 110 can also be detachably connected by magnetic adsorption of a first magnetic member and a second magnetic member. Specifically, the first magnetic member is fixedly arranged on the fixing member 520, and the second magnetic member is fixedly arranged on the connecting arm 110. In this way, when the fixing member 520 moves towards the connecting arm 110, the first magnetic member and the second magnetic member are magnetically adsorbed to each other, thus completing the installation. When disassembling, only a force greater than the magnetic adsorption force needs to be applied to the fixing member 520 to achieve disassembly. The disassembly and assembly are simple and do not require other disassembly and assembly tools, thereby reducing the disassembly and assembly costs.

[0116] In still some other embodiments, the fixing member 520 and the connecting arm 110 can also be detachably connected by snap connection. Exemplarily, a first snap connection portion is arranged on the fixing member 520, and a second snap connection portion is arranged on the connecting arm 110. The first snap connection portion and the second snap connection portion can be snap-connected or disengaged, so as to achieve detachable connection, and the disassembly method is simple. Exemplarily, the first snap connection portion is one of a snap projection and a snap groove, and the second snap connection portion is the other of the snap projection and the snap groove.

[0117] Please continue to refer to Figure 2 、 Figure 3 and Figure 7 and Figure 8 As shown in and, the scooter 10 further includes a bearing 230, an end cap 240, a fastener 260, a nut 270 and a decorative member 250. Among them, the end cap 240 is installed on the load-bearing shaft 420 through the bearing 230, and the end cap 240 is fixedly connected to the connecting arm 110 through the fastener 260. The rocker arm 220 passes through the load-bearing shaft 420 and is located on the side of the end cap 240 away from the connecting arm 110. An external thread is provided at a position near the end of the load-bearing shaft 420, and the nut 270 is threadedly connected to the external thread to limit and fix the rocker arm 220 in the axial direction of the load-bearing shaft 420. In addition, the decorative member 250 is arranged on the side of the rocker arm 220 away from the connecting arm 110. The decorative member 250 can be buckled on the outer periphery of the rocker arm 220 by snap connection or other means. The color and the like of the decorative member 250 match the scooter 10 to improve the aesthetic appearance of the scooter 10 and can also protect the rocker arm 220.

[0118] In some embodiments, the load-bearing shaft 420 at least includes a first sub-load-bearing shaft and a second sub-load-bearing shaft. The first shock-absorbing member 410 is sleeved on the first sub-load-bearing shaft, and the second shock-absorbing member 510 is sleeved on the second sub-load-bearing shaft. Exemplarily, when the first shock-absorbing member 410 is a shock-absorbing cylinder, the radial dimension (or cross-sectional dimension, that is, the dimension perpendicular to the axial direction) of the first sub-load-bearing shaft matches the cross-sectional dimension of the inner hole of the shock-absorbing cylinder, and the radial dimension (or cross-sectional dimension) of the second sub-load-bearing shaft matches the cross-sectional dimension of the socket hole 512 of the second shock-absorbing member 510.

[0119] Among them, the first sub-bearing shaft and the second sub-bearing shaft can be an integral structure formed by casting, injection molding, machining, or the like; alternatively, the first sub-bearing shaft and the second sub-bearing shaft can also be independent of each other; in addition, whether the first sub-bearing shaft and the second sub-bearing shaft are an integral structure or an independent structure, the first sub-bearing shaft and the second sub-bearing shaft can be coaxially arranged or non-coaxially arranged; when the first sub-bearing shaft and the second sub-bearing shaft are independent of each other, the first sub-bearing shaft and the second sub-bearing shaft can be detachably connected to each other (such as snap connection, magnetic attraction), fixedly connected (such as bonding, welding), or not connected to each other, and specific designs can be made according to actual situations, and no specific limitations are made here.

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

[0121] In summary, the scooter provided by the embodiment of the present application includes a frame, a front wheel set, a mounting sleeve, a first shock absorption unit, and at least one second shock absorption unit. The front end of the frame has a connecting arm; the front wheel set 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 absorption unit includes a first shock absorber and a bearing shaft, the bearing shaft is disposed through the mounting sleeve, the first shock absorber is disposed between the peripheral wall of the bearing shaft and the inner wall of the mounting sleeve, the second shock absorption unit is disposed on at least one side of the first shock absorber, and is detachably connected to the bearing shaft and the connecting arm respectively. In this way, the first shock absorption unit can achieve primary shock absorption for the movement between the frame and the front wheel set, and the second shock absorption unit can achieve secondary shock absorption for the movement between the frame and the front wheel set, thereby improving the overall shock absorption effect of the scooter; in addition, the second shock absorption unit is detachably connected to the bearing shaft and the connecting arm respectively, and the user can independently choose whether to add a second shock absorption unit or choose a second shock absorption unit with different shock absorption stiffness, so that the overall shock absorption stiffness of the scooter is adjustable to meet the needs of different users, thereby improving the riding comfort of the user.
