Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motorcycles, in particular to a motorcycle rear fork structure. BACKGROUND

[0002] The seat height of a motorcycle is a clear requirement for motorcycle drivers, but the seat height of a motorcycle is completely different for drivers of different heights and different genders, and even the seat height of a motorcycle is inconsistent for drivers of the same height but different body proportions. The seat height designed during motorcycle research and development is set with reference to the average height of the population, so it is necessary to adjust the height of the motorcycle seat cushion. Most motorcycles on the market cannot adjust the height of the shock absorber assembly due to the fixed position of the rear shock absorber mounting point, thereby affecting the height adjustment of the motorcycle seat cushion. A few rear shock absorbers have multiple rows of mounting holes of different heights arranged in the front-rear direction to achieve an adjustable height range of the shock absorber assembly, but this structure is complex, has poor universality, and is difficult to manufacture and process. SUMMARY

[0003] In order to overcome the above-mentioned problems existing in the prior art, the purpose of the present application is to achieve multiple different seat height adjustments by simply replacing the shock absorber mounting seat assembly without replacing the shock absorber assembly.

[0004] The technical scheme adopted by the present application is as follows: A motorcycle rear fork structure, comprising a fork assembly, the fork assembly comprising a first fork arm and a second fork arm, the first fork arm and the second fork arm being fixedly connected with a cross beam; a rear shock absorber assembly, the rear shock absorber assembly comprising a rear shock absorber, the rear shock absorber being detachably connected with the cross beam and located at the top of the cross beam; a group of connecting pieces provided on the upper surface of the rear shock absorber, the connecting pieces being provided with corresponding eccentric mounting holes. By adopting the above technical scheme, the driver only needs to simply rotate the rear shock absorber by 180 degrees to adjust the displacement of the motorcycle shock absorber assembly in the front-rear direction, thereby achieving the effect of adjusting the height of the motorcycle seat cushion.

[0005] Further, the rear shock absorber assembly further comprises at least one adjusting block, the adjusting block being arranged between the cross beam and the rear shock absorber, and the adjusting block being detachably connected with the rear shock absorber. By adopting the above technical scheme, the height adjustment in the up-down direction of the motorcycle seat cushion is achieved by adding or removing the adjusting block.

[0006] Further, mounting holes are provided in the cross beam, the adjusting block, and the rear shock absorber, and the cross beam, the adjusting block, and the rear shock absorber are connected by fasteners.

[0007] Further, the rear shock absorber further comprises a cross pipe, the cross pipe being fixed to the rear shock absorber through the eccentric mounting hole.

[0008] The motorcycle is provided with the motorcycle rear fork structure. By adjusting the front-rear and up-down positions of the motorcycle shock absorbing assembly mounting point, the installation angle of the motorcycle shock absorbing assembly can be finely controlled, so that the flexibility, accuracy and easy operation of the motorcycle cushion height adjustment are improved.

[0009] In summary, the present application has at least one of the following beneficial effects: by ingeniously designing the detachable connection structure among the cross beam, the adjusting block and the rear shock absorbing seat, and combining the eccentric mounting hole mechanism on the rear shock absorbing seat, the motorcycle shock absorbing assembly can be accurately adjusted in the front-rear and up-down two key degrees of freedom, that is, the driver only needs to simply rotate the rear shock absorbing seat by 180 degrees to easily adjust the front-rear position of the motorcycle shock absorbing assembly, and at the same time, the height of the motorcycle shock absorbing assembly can be flexibly adjusted by increasing or decreasing the adjusting block, thereby directly affecting the height of the motorcycle cushion, greatly improving the flexibility, accuracy and easy operation of the motorcycle cushion height adjustment.

DETAILED DESCRIPTION

[0013] The embodiments of the present application are described below through specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosure of the present specification. The present application can also be implemented or applied through other different specific embodiments, and various modifications or changes can be made to the details in the present specification based on different views and applications without departing from the spirit of the present application.

[0014] The following will be described in detail in combination with the accompanying Figures 1-2 The present application is further described in detail.

[0015] As Figures 1-2As shown, the motorcycle rear flat fork structure disclosed in the present application comprises a flat fork assembly 1 and a rear shock absorbing seat 3 assembly. The flat fork assembly 1 comprises a first fork arm 11 and a second fork arm 12, and a cross beam 13 is fixedly connected between the first fork arm 11 and the second fork arm 12. The rear shock absorbing seat 3 assembly comprises a rear shock absorbing seat 3, and the rear shock absorbing seat 3 is detachably connected with the cross beam 13 and located at the top of the cross beam 13. A group of connecting pieces 31 are arranged on the upper surface of the rear shock absorbing seat 3, and corresponding eccentric mounting holes 32 are formed in the connecting pieces 31. The eccentric mounting hole 32 refers to the connecting hole arranged on one side deviating from the center line of the connecting piece 31, and the eccentric mounting hole 32 is used for mounting the motorcycle shock absorbing assembly. In the embodiment, the detachable connection between the flat fork assembly 1 and the rear shock absorbing seat 3, and the eccentric mounting hole 32 for mounting the motorcycle shock absorbing assembly arranged on the rear shock absorbing seat 3 make the installation position of the motorcycle shock absorbing assembly adjustable in the front-rear direction of the motorcycle, that is, the driver only needs to simply rotate the rear shock absorbing seat 3 by 180 degrees to adjust the displacement of the motorcycle shock absorbing assembly in the front-rear direction, so as to achieve the effect of adjusting the height of the motorcycle cushion. The whole front-rear adjustment mode of the rear shock absorbing seat 3 is ingenious. Compared with the conventional mode, for example, the structure of arranging multiple rows of reserved mounting holes with corresponding and different heights on the rear shock absorbing seat 3, the flexibility and accuracy of adjustment are ensured, the structure is simple, the processing difficulty is low, and the operation is easy, thereby greatly improving the use convenience and satisfaction of the driver.

[0016] The rear shock absorber 3 assembly further comprises at least one adjusting block 2 arranged between the cross beam 13 and the lower surface of the rear shock absorber 3, and the adjusting block 2 is detachably connected with the rear shock absorber 3. The driver adjusts the height of the motorcycle shock absorbing assembly in the up-down direction by reducing or increasing the adjusting block 2, thereby directly affecting the height of the motorcycle seat cushion. In the embodiment, by arranging the detachable connection structure among the cross beam 13, the adjusting block 2 and the rear shock absorber 3, and combining the eccentric mounting hole 32 on the rear shock absorber 3, the motorcycle shock absorbing assembly can be accurately adjusted in two key degrees of freedom, i.e. the front-rear and up-down directions. That is, the driver only needs to simply rotate the rear shock absorber 180 degrees to easily adjust the front-rear position of the motorcycle shock absorbing assembly, or to flexibly adjust the height of the motorcycle shock absorbing assembly by increasing or reducing the adjusting block 2, thereby directly affecting the height of the motorcycle seat cushion, greatly improving the flexibility and accuracy of the adjustment. In addition, the up-down adjustment method has a simple and clear structure, which can be completed without complex tools or professional skills, and the whole operation is simple. At the same time, the driver has a large self-defined modification space, and can customize the number of adjusting blocks 2 to change the thickness of the adjusting blocks 2 to achieve more up-down adjustment methods. In addition, by using detachable connection between the cross beam 13, the adjusting block 2 and the rear shock absorber 3, a highly modularized component is constructed, which is convenient for maintenance, upgrading and personalized customization. It can be widely applied to motorcycles of different models and specifications, saving production and manufacturing costs; due to the reasonable and simple structure design, the processing process is easier to control, thereby improving the production efficiency and product quality.

[0017] During installation, the flat fork assembly 1 is installed on the frame, the cross beam 13 of the flat fork assembly 1 is provided with four first mounting holes 131, the adjusting block 2 is provided with second mounting holes 21 corresponding to the first mounting holes 131, the rear shock absorber 3 is provided with third mounting holes 33 corresponding to the first mounting holes 131 and the second mounting holes 21, and the bolts 4 pass through the third mounting holes 33 on the rear shock absorber 3, the second mounting holes 21 of the adjusting block 2 and the first mounting holes 131 on the cross beam 13 in sequence, and fix the rear shock absorber 3 and the adjusting block 2 on the cross beam 13. In the embodiment, the first mounting holes 131, the second mounting holes 21 and the third mounting holes 33 can be arranged according to requirements, and are not limited to four corresponding mounting holes. The whole is detachably connected and fixed by the same fixing member. Compared with the prior art rear shock absorber 3 adjustable structure which reserves one or more mounting holes, the number of mounting holes is reduced in the embodiment, and the appearance is beautiful.

[0018] As Figure 3As shown, the rear shock absorber mount 3 also includes a horizontal tube 34, which is welded to the rear shock absorber mount 3 through eccentric mounting holes 32. The length of the horizontal tube 34 is greater than the distance between the two eccentric mounting holes 32 provided on the connecting piece 31. In this embodiment, by setting the length of the horizontal tube 34 to be greater than the distance between the two eccentric mounting holes 32 provided on the connecting piece 31, it is convenient to install the motorcycle shock absorber assembly outside the rear shock absorber mount.

[0019] This application discloses a rear swingarm structure for motorcycles, including a swingarm assembly 1 and a rear shock absorber mount 3 assembly. The swingarm assembly 1 includes a first fork arm 11 and a second fork arm 12, with a crossbeam 13 fixedly connected between the first fork arm 11 and the second fork arm 12. The rear shock absorber mount 3 assembly includes a rear shock absorber mount 3, which is detachably connected to the crossbeam 13 and located on top of the crossbeam 13. The surface of the rear shock absorber mount 3 is provided with a height adjustment structure, which consists of an adjustment block 2 disposed on the lower surface of the rear shock absorber mount 3. At least one adjustment block 2 is provided, and the adjustment block 2 is detachably connected to the rear shock absorber mount 3. In this embodiment, by detachably connecting the crossbeam 13, the adjustment block 2, and the rear shock absorber mount 3, the height of the motorcycle seat can be changed. The rider only needs to add or remove the adjustment block 2 to adjust the height of the motorcycle shock absorber assembly in the vertical direction, thus directly affecting the height of the motorcycle seat. The vertical adjustment method is simple in structure and operation. Meanwhile, drivers have a large space for customization and modification, and can customize the number of adjustment blocks 2 to change the thickness of the entire adjustment block 2 to achieve more vertical adjustment methods.

[0020] In this embodiment, a set of connecting plates 31 are provided on the upper surface of the rear shock absorber 3, and corresponding eccentric mounting holes 32 are provided on the connecting plates 31. By setting the crossbeam 13, the adjusting block 2 and the rear shock absorber 3 to be detachably connected, and combined with the eccentric mounting holes 32 provided on the upper surface of the rear shock absorber 3, the motorcycle shock absorber assembly can be adjusted in two degrees of freedom: front-to-back and up-to-down. That is, the driver only needs to rotate the rear shock absorber 3 180 degrees to adjust the front-to-back mounting position of the motorcycle shock absorber assembly, or adjust the height of the motorcycle shock absorber assembly in the up-to-down direction by adding or removing the adjusting block 2. The rear shock absorber 3 has a clever front-to-back adjustment method, a simple up-to-down adjustment method, and is easy to operate.

[0021] This application also discloses a motorcycle equipped with the motorcycle swingarm assembly of any of the above embodiments, enabling height adjustment of the motorcycle seat. By adjusting the fore-and-aft and vertical positions of the motorcycle shock absorber assembly mounting points, the mounting angle of the motorcycle shock absorber assembly can be precisely controlled, thereby changing the lever ratio of the motorcycle's rear suspension. This change directly affects the dynamic response and stability of the motorcycle suspension system. Combined with adaptive adjustments to the motorcycle seat, it can significantly improve the motorcycle's suspension comfort (for long-distance travel or daily commuting) or sport performance (for competitive riding or aggressive handling), meeting personalized needs in different riding scenarios. Simultaneously, this embodiment closely links the characteristics of the motorcycle suspension system with the rider's body posture, adapting to different riders' heights, weights, and riding habits. This not only optimizes the rider's seating comfort and reduces fatigue during long rides but also enhances control and safety during riding by adjusting the riding posture, resulting in a higher level of riding experience and enjoyment.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application, and all such modifications or substitutions should be covered within the scope of the claims of this application.
