[0059] As a specific embodiment of the present utility model, as shown in Figures 1-3 The present embodiment provides a scooter 100, which can include a frame 200 and at least one wheel assembly (not shown in the figure), and each wheel assembly is connected to the frame 200 through at least one suspension module 300. Each suspension module 300 can include at least one pivoting connecting assembly, which is connected to the wheel assembly and the frame 200 through the at least one pivoting connecting assembly. The at least one pivoting connecting assembly can include a connecting shaft and at least one bushing arranged outside the connecting shaft, and the surface of the at least one bushing is provided with a lubricating coating to eliminate abnormal noise at the connection between the suspension module and the frame and at the connection between the suspension module and the wheel assembly. Here, the surface of the bushing can be the inner surface or the outer surface.

[0060] Specifically, the suspension module 300 of the embodiment can be used to connect the wheel assembly and the frame 200, and the suspension module 300 comprises at least one pivot connection assembly, the at least one pivot connection assembly can comprise a connecting shaft and at least one bushing arranged outside the connecting shaft, and the surface of the at least one bushing is provided with a lubricating coating, so that when the relative rotation occurs between the frame and the suspension module 300, the abnormal sound is reduced or eliminated due to the existence of the lubricating coating, and when the relative rotation occurs between the wheel assembly and the suspension module 300, the abnormal sound is reduced or eliminated due to the existence of the lubricating coating, the abnormal sound of the scooter 100 in use is reduced or eliminated, and the use experience of the whole scooter 100 is improved.

[0061] Specifically, the surface in the embodiment is not limited to the inner surface, the outer surface or the contact surface with other elements of the bushing, but is a general surface.

[0062] As a specific embodiment of the utility model, the frame 200 of the embodiment can comprise a first connecting part 210 and a second connecting part 220 located above the first connecting part 210. The pivot connection assembly can comprise a first pivot connection assembly 600, a second pivot connection assembly 700 and / or a third pivot connection assembly 800. Each suspension module 300 can comprise a rocker arm assembly 400 and a shock absorber 500. One end of the rocker arm assembly 400 is pivotally connected with the first connecting part 210 through the first pivot connection assembly 600, and the other end is connected with the wheel assembly. One end of the shock absorber 500 is pivotally connected with the second connecting part 220 through the second pivot connection assembly 700, and the other end of the shock absorber 500 is pivotally connected with the rocker arm assembly 400 through the third pivot connection assembly 800. Wherein, the first pivot connection assembly 600 can comprise at least one first connecting shaft 610 and at least one first bushing 710. Wherein, the surface of the at least one first bushing 710 is provided with a lubricating coating. The second pivot connection assembly 700 can comprise at least one second connecting shaft 620 and at least one second bushing 720. Wherein, the surface of the at least one second bushing 720 is provided with a lubricating coating. The third pivot connection assembly 800 can comprise at least one third connecting shaft 630 and at least one third bushing 730; wherein, the surface of the at least one third bushing 730 is provided with a lubricating coating.

[0063] Specifically, in the embodiment, the frame 200 and the wheel assembly are connected through the suspension module 300, and the suspension module 300 can include the rocker assembly 400 and the shock absorber 500. In order to maintain balance, a triangular structure is formed between the rocker assembly 400, the shock absorber 500, and the frame 200, and therefore the frame 200 needs to be provided with two different connection portions, i.e., the first connection portion 210 and the second connection portion 220. In order to ensure that the frame 200 is damped by the shock absorber 500 when subjected to downward pressure, the first connection portion 210 and the second connection portion 220 on the frame 200 need to be arranged in an up-down manner. In one embodiment, the second connection portion 220 can be directly below the first connection portion 210, and of course can also be arranged at a position other than directly below. In the embodiment, the second connection portion 220 is directly below the first connection portion 210.

[0064] In addition, the wheel assembly in the embodiment is the rear wheel of the scooter 100, and since the body has a certain width, the number of wheels in the rear wheel assembly of the scooter 100 is generally only one. In order to maintain balance, two groups of suspension modules 300 are provided in the embodiment, and the first connection portion 210 and the second connection portion 220 cooperate with each group of suspension modules 300. The two suspension modules 300 are arranged in a mirror-symmetrical manner. Of course, in other embodiments, the number of suspension modules 300 can be designed according to the situation. The following describes an example in which one of the suspension modules 300 is connected to the frame 200 and the wheel assembly.

[0065] Specifically, in the embodiment, one end of the rocker assembly 400 is pivotally connected to the first connection portion 210 through the first pivot connection assembly 600, and the other end is connected to the wheel assembly. One end of the shock absorber 500 is pivotally connected to the second connection portion 220 through the second pivot connection assembly 700, and the other end is pivotally connected to the other end of the rocker assembly 400 through the third pivot connection assembly 800. Specifically, the connection between the shock absorber 500 and the rocker assembly 400 can be located at a position between the first connection portion 210 and the rotating shaft of the wheel of the wheel assembly. The positions of each pivot connection are connected together through a connecting shaft, and therefore, during use of the scooter 100, relative rotation occurs at each pivot connection.

[0066] As one of the embodiments, at least one bushing can be arranged outside the connecting shaft at any one of the pivot connections, and a lubricating coating is arranged outside the at least one bushing. In this way, abnormal noise at one of the pivot connections can be reduced or eliminated. For example, at least one first bushing 710 is arranged outside the first connecting shaft 610 at the pivot connection between the rocker assembly 400 and the first connection portion 210, and a lubricating coating is arranged outside the at least one first bushing 710. In this way, abnormal noise can be reduced when the rocker assembly 400 and the first connection portion 210 rotate relative to each other. The same applies to the other two positions, which are not described here.

[0067] As another embodiment, at least one bushing 700 is provided outside the connecting shaft of any one of the two pivot connections, and a lubricating coating is provided outside the at least one bushing 700. In this way, the noise at the two pivot connections can be reduced or eliminated.

[0068] As another embodiment, at least one bushing 700 is provided outside the connecting shaft of any one of the two pivot connections, and a lubricating coating is provided outside the at least one bushing 700. In this way, the noise at the two pivot connections can be reduced or eliminated.

[0069] Specifically, the embodiment is achieved by providing a suspension module 300 between the frame 200 and the wheel assembly, and the suspension module 300 can further include a rocker arm assembly 400 and a shock absorber 500. The rocker arm assembly 400 is pivotally connected to the first connecting portion 210 through at least one first connecting shaft 610 and at least one first bushing 710. The surface of the at least one first bushing 710 is provided with a lubricating coating. The shock absorber 500 is pivotally connected to the second connecting portion 220 through at least one second connecting shaft 620 and at least one second bushing 720. The surface of the at least one second bushing 720 is provided with a lubricating coating. The shock absorber 500 is pivotally connected to the rocker arm assembly 400 through at least one third connecting shaft 630 and at least one third bushing 730. The surface of the at least one third bushing 730 is provided with a lubricating coating. The noise at the pivot connections of the scooter 100 during use can be effectively reduced or eliminated. In addition, compared with the rubber bushing used in the conventional shock absorber, the rubber will be pulled off and fail due to its own elongation rate exceeding the stroke. The use of the bushing can enable the rotary connection to rotate through a larger angle without the risk of failure, thereby enabling the wheel assembly to have a larger wheel jump stroke and enabling the scooter 100 to have higher riding comfort.

[0070] As a specific embodiment of the utility model, as Figure 3 , Figure 4 and Figure 5As shown, the end of the damper 500 of the embodiment connected with the second connecting part 220 can include a first through hole 510, and the second connecting part 220 can include a second through hole 221. The second connecting shaft 620 is arranged through the first through hole 510 and the second through hole 221. In one embodiment, at least one second bushing 720 is arranged between the first through hole 510 and the second connecting shaft 620. Alternatively, in another embodiment, at least one second bushing 720 is arranged between the second through hole 221 and the second connecting shaft 620. Alternatively, in still another embodiment, at least one second bushing 720 is arranged between the first through hole 510 and the second connecting shaft 620, and at least one second bushing 720 is also arranged between the second through hole 221 and the second connecting shaft 620.

[0071] As a specific embodiment of the utility model, the contact surface of the second bushing 720 of the embodiment and the second connecting shaft 620 is parallel to the extension direction of the second connecting shaft 620. The contact surface of the second bushing 720 and the first through hole 510 and / or the second through hole 221 is parallel to the extension direction of the second connecting shaft 620.

[0072] Specifically, the cross section of each second bushing 720 of the embodiment perpendicular to the axial direction of the connecting shaft is a circular ring. The innermost second bushing 720 is sleeved outside the second connecting shaft 620 and in contact with the outer surface of the second connecting shaft 620. The contact surface is parallel to the second connecting shaft 620. The outermost second bushing 720 is in contact with the inner surface of the first through hole 510 and / or the second through hole 221, and the contact surface is parallel to the axis of the second connecting shaft 620. In this way, the damper 500 and the second connecting part 220 can rotate relative to the axis of the second connecting shaft 620.

[0073] As a specific embodiment of the utility model, the number of the second bushing 720 of the embodiment is one, and the inner surface and / or the outer surface of the second bushing 720 is provided with a lubricating coating.

[0074] Specifically, if the number of the second bushing 720 of the embodiment is one, as one of the embodiments, the inner surface of the second bushing 720 of the embodiment is provided with a lubricating coating, the second bushing 720 needs to be interference fit with the first through hole 510 or the second through hole 221, the second bushing 720 moves together with the damper 500 or the second connecting part 220, the second bushing 720 rotates relative to the second connecting shaft 620, thereby ensuring that the damper 500 and the second connecting part 220 do not produce abnormal sound when rotating relative to each other.

[0075] As another specific embodiment, the outer surface of the second bushing 720 of the present embodiment is provided with a lubricating coating, the second bushing 720 is in interference fit with the second connecting shaft 620 and moves together, the second bushing 720 rotates relative to the inner surface of the first through hole 510 or the inner surface of the second through hole 221, thereby ensuring that no noise is generated when the shock absorber 500 and the second connecting part 220 rotate relative to each other.

[0076] As still another specific embodiment, the inner surface and the outer surface of the second bushing 720 of the present embodiment are both provided with a lubricating coating. In this case, no noise is generated when the shock absorber 500 and the second connecting part 220 rotate relative to each other.

[0077] Specifically, if the number of the second bushings 720 is multiple, the multiple second bushings 720 are sequentially sleeved radially outward from the second connecting shaft 620. The lubricating coating is provided at the contact position between the second bushing 720 and the second connecting shaft 620, between adjacent two second bushings 720, or / and outside the outermost second bushing 720.

[0078] Specifically, when the number of the second bushings 720 is multiple, in the least case, only the inner surface or the outer surface of one second bushing 720 is provided with a lubricating coating, and the other components are in interference fit and do not rotate relative to each other, and the shock generated when the shock absorber 500 and the second connecting part 220 rotate relative to each other is reduced by the lubricating effect of the lubricating coating. As another specific embodiment, the inner surface and the outer surface of all the second bushings 720 of the present embodiment are provided with a lubricating coating, and in this case, the noise is reduced by the lubricating coating when the shock absorber 500 and the second connecting part 220 rotate relative to each other. In other embodiments, the inner surface and / or the outer surface of one or more second bushings 720 are selectively provided with a lubricating coating, and the two components without the lubricating coating are in interference fit and do not rotate relative to each other. In this way, the noise generated when the shock absorber 500 and the second connecting part 220 rotate relative to each other can be reduced.

[0079] As a specific embodiment of the present application, the second pivot connecting assembly 700 of the present embodiment can further include a first gasket 810 sleeved outside the second connecting shaft 620, the first gasket 810 is located between the shock absorber 500 and the second connecting part 220, and the contact surfaces of the first gasket 810 and the shock absorber 500 and the second connecting part 220 both extend perpendicular to the extension direction of the second connecting shaft 620.

[0080] Specifically, the first gasket 810 is provided outside the second connecting shaft 620, and the first gasket 810 is annular and sleeved outside the second connecting shaft 620, and the first gasket 810 is in contact with the shock absorber 500 and the vehicle frame 200, and the contact surface extends perpendicularly to the extending direction of the second connecting shaft 620. Specifically, the first gasket 810 is provided to reduce the abnormal sound caused by the axial contact between the shock absorber 500 and the vehicle frame 200 when the shock absorber 500 and the vehicle frame 200 rotate relative to each other.

[0081] As a specific embodiment of the utility model, the first gasket 810 is provided with a lubricating coating at the contact position of the shock absorber 500, the second connecting part 220 and the second bushing 720.

[0082] Specifically, the first gasket 810 is provided with a lubricating coating or the first gasket 810 is made of self-lubricating material, so that the first gasket 810 and the shock absorber 500 or the second connecting part 220 are in a lubricating state, thereby ensuring that the side of the shock absorber 500 in contact with the second connecting part 220 does not produce abnormal sound when the shock absorber 500 and the vehicle frame 200 rotate relative to each other.

[0083] As a specific embodiment, the first gasket 810 is provided with a lubricating coating, and the lubricating coating is made of graphite or molybdenum disulfide. Figure 5 and Figure 6As shown in the embodiment, the upper end of the damper 500 is formed with a first through hole 510, and the second connecting portion 220 is formed with two connecting lugs 222 located at the upper end of the damper 500, and a second through hole 221 is arranged at each connecting lug 222.

The number of the second bushings 720 can be two, and the two second bushings 720 are sleeved outside the second connecting shaft 620 and inside the first through hole 510. And the two second bushings 720 are arranged between the two connecting lugs 222. Among them, the inner second bushing 720 can be in interference fit with the second connecting shaft 620 without relative rotation. The two sides of the inner second bushing 720 abut against the two connecting lugs 222. The outer second bushing 720 is in interference fit with the first through hole 510 of the damper 500 without relative rotation. The second connecting shaft 620 is in interference fit with the two connecting lugs 222 without relative rotation. A lubricating coating is arranged between the two second bushings 720.

The number of the first gaskets 810 is two, which are arranged between the outer second bushing 720 and the damper 500 and the two connecting lugs 222, respectively. The first gaskets 810 are made of self-lubricating material. When the damper 500 and the second connecting portion 220 rotate relative to each other, the damper 500 moves together with the outer second bushing 720, and the inner second bushing 720 moves together with the second connecting shaft 620 and the second connecting portion 220. The outer second bushing 720 moves relative to the inner second bushing 720, thereby avoiding abnormal noise caused by the relative rotation of the damper 500 and the second connecting shaft 620.
