[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] like Figures 1 to 3 As shown, the present invention provides an adjustment mechanism 1, which mainly includes an adjustment seat 11, an adjustment component and a connecting shaft 14.

[0035] The adjusting seat 11 is provided with an adjusting hole 113 and a connecting hole 114. The adjusting hole 113 penetrates the adjusting seat 11 along a first direction, and the connecting hole 114 penetrates the adjusting seat 11 along a second direction. The first direction and the second direction are orthogonal. For ease of explanation, as follows Figure 1 As shown, the first direction is the left-right direction, and the second direction is the up-down direction. That is, the adjustment hole 113 passes through the adjustment seat 11 from left to right, and the connecting hole 114 passes through the adjustment seat 11 from top to bottom.

[0036] Furthermore, the connecting shaft 14 is eccentrically positioned within the adjusting hole 113, and an adjusting member is also positioned within the adjusting hole 113. The adjusting member drives the connecting shaft 14 to move within the adjusting hole 113, thereby adjusting the perpendicular distance between the axis of the connecting shaft 14 and the axis of the connecting hole 114. More specifically, as... Figure 3 As shown, the inner diameter of the adjusting hole 113 is larger than the outer diameter of the connecting shaft 14. The connecting shaft 14 can move not only along the axial direction of the adjusting hole 113, but also along the radial direction of the adjusting hole 113, thereby achieving the eccentric setting of the connecting shaft 14, that is, the axis of the connecting shaft 14 and the axis of the adjusting hole 113 are not on the same straight line.

[0037] It is understandable that the perpendicular distance between the axis of the adjusting hole 113 and the axis of the connecting hole 114 remains constant. However, the adjusting member can drive the connecting shaft 14 to move radially within the adjusting hole 113, thereby changing the perpendicular distance between the axis of the connecting shaft 14 and the axis of the connecting hole 114. This allows for the adjustment of the position of the connecting shaft 14. By using the adjusting member to adjust the positional relationship between the connecting shaft 14 and the connecting hole 114, the adjustment is more convenient and adaptable.

[0038] In some embodiments, such as Figures 1 to 3 As shown, the adjusting component includes an adjusting sleeve 12, which is sleeved on the connecting shaft 14. The adjusting sleeve 12 can rotate relative to the connecting shaft 14. The adjusting sleeve 12 passes through the adjusting hole 113 and can rotate relative to the adjusting hole 113. The axis of the adjusting sleeve 12 and the axis of the adjusting hole 113 are on the same straight line. The axis of the adjusting sleeve 12 and the axis of the connecting shaft 14 are parallel but on different straight lines.

[0039] Furthermore, since the axis of the adjusting sleeve 12 and the axis of the adjusting hole 113 are on the same straight line, the adjusting sleeve 12 can rotate within the adjusting hole 113. More specifically, the outer diameter of the adjusting sleeve 12 is adapted to the inner diameter of the adjusting hole 113. For example, the adjusting sleeve 12 and the adjusting hole 113 are in a transition fit. While enabling the adjusting sleeve 12 to rotate within the adjusting hole 113, the adjusting hole 113 can also prevent the adjusting sleeve 12 from rotating to a certain extent.

[0040] Specifically, the two ends of the adjusting sleeve 12 extend in the left and right directions, and the adjusting sleeve 12 wraps around the connecting shaft 14. Since the axis of the adjusting sleeve 12 is parallel to the axis of the connecting shaft 14 and is located on different straight lines, that is, the connecting shaft 14 is eccentrically located inside the adjusting sleeve 12, when the adjusting sleeve 12 is rotated, the connecting shaft 14 will rotate around the axis of the adjusting sleeve 12, that is, the connecting shaft 14 will move circumferentially along the adjusting sleeve 12. It can be understood that the connecting shaft 14 will also move circumferentially along the adjusting hole 113, thereby realizing the change of the radial position of the connecting shaft 14 in the adjusting hole 113, and also causing the perpendicular distance between the axis of the connecting shaft 14 and the axis of the connecting hole 114 to change, thereby realizing the adjustment of the position of the connecting shaft 14. By rotating the adjusting sleeve 12, the position of the connecting shaft 14 in the adjusting hole 113 is adjusted, thereby changing the positional relationship between the connecting shaft 14 and the connecting hole 114, making the adjustment more convenient and adaptable.

[0041] In some other embodiments, the adjusting member can also be made of an elastic material, such as rubber. It is understood that the inner diameter of the adjusting hole 113 is larger than the outer diameter of the connecting shaft 14, and there is a gap between the adjusting hole 113 and the connecting shaft 14. In addition to driving the connecting shaft 14 to change position, the adjusting member also fixes the position of the connecting shaft 14 in the adjusting hole 113. By filling the gap between the adjusting hole 113 and the connecting shaft 14 with an elastic material such as rubber, the connecting shaft 14 can be fixed. Specifically, when it is necessary to adjust the position of the connecting shaft 14 in the adjusting hole 113, take out the rubber part, and then change the position of the connecting shaft 14 in the adjusting hole 113 so that the perpendicular distance between the axis of the connecting shaft 14 and the axis of the connecting hole 114 changes. Then, fill the gap between the adjusting hole 113 and the connecting shaft 14 with the rubber part to fix the position of the connecting shaft 14 in the adjusting hole 113, thereby realizing the adjustment of the position of the connecting shaft 14. The position change of the connecting shaft 14 can also be realized, which is very convenient to use.

[0042] In some embodiments, such as Figure 2 As shown, the adjusting bushing 12 includes a first bushing 121 and a second bushing 122. The first bushing 121 and the second bushing 122 are detachably connected. The connecting shaft 14 is located between the first bushing 121 and the second bushing 122. When the first bushing 121 and the second bushing 122 are assembled together, a bushing hole is formed between the first bushing 121 and the second bushing 122. The axis of the bushing hole is parallel to the axis of the adjusting bushing 12 and is located on different straight lines. The axis of the bushing hole is on the same straight line as the axis of the connecting shaft 14. The connecting shaft 14 passes through the bushing hole. Rotating the adjusting bushing 12 can drive the connecting shaft 14 to move, making adjustment more convenient.

[0043] More specifically, the outer diameter of the connecting shaft 14 is matched with the inner diameter of the bushing hole. For example, the connecting shaft 14 and the bushing hole are in a transition fit. While enabling the connecting shaft 14 to rotate in the bushing hole, the bushing hole can also prevent the connecting shaft 14 from rotating to a certain extent.

[0044] In some embodiments, the first bushing 121 and the second bushing 122 can be detachably connected by screws, which is very convenient for both disassembly and assembly.

[0045] In some embodiments, the first bushing 121 and the second bushing 122 can be detachably connected by snap-fit, making it very convenient to disassemble or assemble them together.

[0046] In some other embodiments, the adjusting bushing 12 is an integrally formed structure, and the adjusting bushing 12 is also provided with a bushing hole to accommodate the connecting shaft 14, making the overall structure more stable.

[0047] In some embodiments, such as Figures 1 to 3 As shown, the adjusting component also includes a rotating part 13. Both ends of the adjusting sleeve 12 are provided with rotating parts 13, which are located on the outside of the adjusting seat 11. Specifically, the rotating parts 13 are located at the left and right ends of the adjusting sleeve 12. The outer diameter of the rotating parts 13 is larger than the outer diameter of the adjusting sleeve 12. Viewed from the side, the rotating parts 13 protrude from the adjusting sleeve 12. Since the rotating parts 13 are located on the left and right sides of the adjusting seat 11, when adjusting the position of the connecting shaft 14, it is not necessary to rotate the adjusting sleeve 12. Simply rotating the rotating parts 13 located outside the adjusting seat 11 will drive the adjusting sleeve 12 to rotate, thereby driving the connecting shaft 14 to move, thus achieving the adjustment of the position of the connecting shaft 14, making adjustment more convenient.

[0048] In some embodiments, the rotating part 13 is further provided with a plurality of anti-slip protrusions. The plurality of anti-slip protrusions are arranged at intervals along the circumference of the rotating part 13, and the plurality of anti-slip protrusions protrude from the surface of the rotating part 13 along the radial direction of the rotating part 13. When adjusting, the rotating part 13 can be rotated by hand or wrench or other tools. The anti-slip protrusions can increase the friction between the rotating part 13 and the contact surface of the hand or wrench or other tools, so that the rotating part 13 can be rotated more stably and is more convenient to operate.

[0049] In some embodiments, such as Figures 1 to 3As shown, the adjusting seat 11 includes a first fixed seat 111 and a second fixed seat 112, with an adjusting hole 113 formed between the first fixed seat 111 and the second fixed seat 112. An adjusting bushing 12 is located between the first fixed seat 111 and the second fixed seat 112. The first fixed seat 111 and the second fixed seat 112 are detachably connected, for example, by screws, making installation and disassembly very convenient. In some other embodiments, the first fixed seat 111 and the second fixed seat 112 can also be detachably connected by snap-fit ​​mechanisms, which also makes assembly and disassembly very convenient.

[0050] In some embodiments, such as Figures 1 to 3 As shown, the connecting hole 114 is provided on the first fixing seat 111. The first fixing seat 111 has a boss 15 on the side near the second fixing seat 112. The side of the second fixing seat 112 near the adjusting hole 113 is in contact with the first fixing seat 111. The side of the second fixing seat 112 near the connecting hole 114 is in contact with the boss 15. The first fixing seat 111 and the second fixing seat 112 are connected by screws. The first fixing seat 111 and the second fixing seat 112 are each provided with a corresponding threaded hole.

[0051] Specifically, viewed from the side, the length of the first fixing seat 111 is greater than the length of the second fixing seat 112. The bottom surface of the first fixing seat 111 is provided with a downwardly protruding boss 15. The second fixing seat 112 is located below the first fixing seat 111 and in front of the boss 15. The top surface of the second fixing seat 112 is in contact with the bottom surface of the first fixing seat 111, and the rear side of the second fixing seat 112 is in contact with the front side of the boss 15. The boss 15 is designed to prevent mistakes. When installing the adjusting seat 11, the second fixing seat 112 can be attached to the first fixing seat 111 more quickly, and the threaded hole on the second fixing seat 112 can be aligned with the threaded hole on the first fixing seat 111 more quickly, which can effectively improve the installation efficiency of the adjusting seat 11.

[0052] In some embodiments, the connecting hole 114 is provided at the boss 15. When disassembling and assembling the overall structure, the second fixing seat 112 can be disassembled separately, or the component located in the connecting hole 114 can be disassembled separately, such as the connecting rod connected to the handlebar. This reduces the correlation between the components during disassembly and assembly, and avoids affecting the whole body by moving one part, making disassembly and assembly more convenient and efficient.

[0053] like Figures 1 to 3 As shown, the present invention also provides a front fork device, including a clamping member 2 and the aforementioned adjustment mechanism 1.

[0054] The clamping component 2 includes two clamping blocks 21, which are respectively located at both ends of the connecting shaft 14 and on the outside of the adjusting seat 11. The clamping blocks 21 are provided with clamping holes 211. Specifically, the two clamping blocks 21 are located at the left and right ends of the connecting shaft 14 and on the left and right sides of the adjusting seat 11, respectively. The rotating part 13 is located between the clamping blocks 21 and the adjusting seat 11. It can be understood that the adjusting seat 11 and the clamping blocks 21 can jointly apply pressure to the rotating part 13, thereby clamping the rotating part 13 and preventing the rotating part 13 from rotating to a certain extent. That is, it can also prevent the adjusting bushing 12 from rotating to a certain extent, making the overall structure more stable.

[0055] Furthermore, such as Figure 1 As shown, the clamping block 21 includes a first clamping arm 212 and a second clamping arm 213. A clamping hole 211 is formed between the first clamping arm 212 and the second clamping arm 213. The first clamping arm 212 is connected to the connecting shaft 14. The second clamping arm 213 is located on the side of the first clamping arm 212 away from the connecting shaft 14. One end of the second clamping arm 213 is connected to the first clamping arm 212, and the other end of the second clamping arm 213 is detachably connected to the first clamping arm 212, for example, by means of screws. This makes it easier to disassemble and assemble the parts located in the clamping hole 211, resulting in higher disassembly and assembly efficiency.

[0056] Furthermore, there are two adjusting mechanisms 1 and two clamping members 2. The two adjusting mechanisms 1 are connected to the two clamping members 2 respectively. The two adjusting mechanisms 1 are spaced apart along the second direction. The two connecting holes 114 in the two adjusting mechanisms 1 are coaxial. More specifically, each adjusting seat 11 has clamping blocks 21 on its left and right sides. The two adjusting seats 11 are arranged in the vertical direction. The axes of the two connecting holes 114 in the two adjusting seats 11 are on the same straight line. It can be understood that the axes of the two clamping holes 211 on the same side are also on the same straight line, which can better install rod-shaped components in the clamping holes 211 and the connecting holes 114.

[0057] Specifically, such as Figures 4 to 6 As shown, the front fork assembly also includes a first connecting rod 3 and a second connecting rod 4. The first connecting rod 3 is inserted into a connecting hole 114, and there are two second connecting rods 4. The two second connecting rods 4 are spaced apart along the first direction and are respectively inserted into two clamping holes 211 in the same clamping member 2. More specifically, the lower end of the first connecting rod 3 passes through the connecting hole 114 of one of the adjusting seats 11 and is inserted into the connecting hole 114 of the other adjusting seat 11 located on the lower side. The upper end of the first connecting rod 3 is connected to the handlebars, and the upper end of the second connecting rod 4 is sequentially inserted into the clamping holes 211 of the two clamping blocks 21 located on the same side. The lower end of the second connecting rod 4 is connected to the axle of the front wheel 5, thereby realizing the connection, fixation, and guidance functions of the entire front fork assembly.

[0058] The present invention also provides a two-wheeled vehicle, including a vehicle body and the aforementioned front fork assembly. The front fork assembly is located on the front side of the vehicle body. More specifically, the vehicle body includes a frame, a front wheel 5, and a rear wheel. The upper end of the front fork assembly is connected to the handlebars, and the lower end of the front fork assembly is connected to the axle of the front wheel 5. In its most primitive state, viewed from the side, as shown... Figure 4 As shown, the first connecting rod 3 and the second connecting rod 4 are in a parallel state, and the entire vehicle body can be understood as being in a horizontal state.

[0059] When it is necessary to adjust the attitude of the entire vehicle body, the attitude of the entire vehicle body can be changed by adjusting the adjustment mechanism 1. Specifically, for example... Figure 5 As shown, keeping the lower adjustment mechanism 1 stationary, only the upper adjustment mechanism 1 is adjusted. In the upper adjustment mechanism 1, the position of the connecting shaft 14 is changed, shortening the vertical distance between the connecting shaft 14 and the connecting hole 114. This causes the upper clamping member 2 to be closer to the first connecting rod 3 than the lower clamping member 2. During this process, the positions of the two clamping holes 211 on the same side can be adjusted by rotating the two connecting shafts 14 themselves, so that the two clamping holes 211 on the same side can always remain coaxial. At this time, the first connecting rod 3 and the second connecting rod 4 are no longer parallel, and an angle is formed between the first connecting rod 3 and the second connecting rod 4. At this time, the distance between the front wheel 5 and the rear wheel increases, and the front of the vehicle body will also drop, forming a diving posture. When it is necessary to increase the speed of sprinting or going downhill, the user can adjust the entire two-wheeled vehicle to this posture to meet different driving conditions and different usage needs, thus making it more adaptable.

[0060] In addition, such as Figure 6 As shown, the lower adjustment mechanism 1 can be kept stationary, and only the upper adjustment mechanism 1 can be adjusted. In the upper adjustment mechanism 1, the position of the connecting shaft 14 is changed, increasing the vertical distance between the connecting shaft 14 and the connecting hole 114. This causes the upper clamping member 2 to move further away from the first connecting rod 3 than the lower clamping member 2. During this process, the positions of the two clamping holes 211 on the same side can be adjusted by rotating the two connecting shafts 14 themselves, so that the two clamping holes 211 on the same side can always remain coaxial. At this time, the first connecting rod 3 and the second connecting rod 4 are no longer parallel, and an angle is formed between the first connecting rod 3 and the second connecting rod 4. At this time, the distance between the front wheel 5 and the rear wheel decreases, and the front of the vehicle body also rises, forming an upward posture. When it is necessary to increase the uphill speed, the user can adjust the entire two-wheeled vehicle to this posture to meet different driving conditions and different usage needs, thus making it more adaptable.

[0061] Furthermore, two adjustment mechanisms 1 can be adjusted simultaneously, that is, the vertical distance between the two connecting shafts 14 and the two connecting holes 114 can be increased or decreased at the same time, so that the distance between the first connecting rod 3 and the second connecting rod 4 can be increased or decreased at the same time. The first connecting rod 3 and the second connecting rod 4 are still in a parallel state. Through this adjustment method, the trail of the front wheel 5 can be changed, thereby meeting different driving conditions and different usage needs, and the adaptability is better.

[0062] It is understandable that the above are just some of the adjustment methods. Different adjustment methods can be achieved through different parameter settings. Parameters such as wheelbase, trail, fork rake angle, fork offset distance, and fork extension can be adjusted to meet different driving conditions and different usage needs, thus making it more adaptable.

[0063] In some embodiments, two-wheeled vehicles include, but are not limited to, human-powered bicycles, electric bicycles, motorcycles, and other two-wheeled vehicles.

[0064] In some other embodiments, the aforementioned front fork device can be applied not only to two-wheeled vehicles but also to three-wheeled vehicles, such as human-powered tricycles and electric tricycles.

[0065] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
