Technical Field

[0001] The utility model relates to the technical field of scooters, in particular to a front fork assembly and a scooter. Background Art

[0002] Scooters are a convenient, environmentally friendly and economical means of transportation suitable for people of all ages. Both manual scooters and electric scooters have their unique advantages and application scenarios.

[0003] A scooter generally comprises a handlebar, a front fork, a front wheel, a rear wheel and a pedal, wherein the front wheel is connected to the front fork, the front fork is connected to the handlebar, and the pedal is used to connect the front wheel and the rear wheel.

[0004] However, since the connection between the front wheel and the front fork is usually exposed to the air, sand, gravel, debris, etc. stirred up by the scooter during driving can easily impact the connection between the front wheel and the front fork, thereby causing the connection between the front wheel and the front fork to be easily damaged. Utility Model Content

[0005] The embodiment of the present application provides a front fork assembly and a scooter. The front fork assembly can prevent sand, gravel, debris, etc. stirred up by the scooter during driving from colliding with the connection between the front wheel and the front fork by providing a decorative cover, thereby extending the service life of the connection between the front wheel and the front fork.

[0006] A first aspect of an embodiment of the present application provides a front fork assembly, wherein the front fork assembly is used to connect to the front wheel of a scooter, and comprises:

[0007] A front fork leg, one end of which is provided with a connecting foot, the connecting foot being used to connect to the front wheel;

[0008] The decorative cover is plugged into and matched with the connecting pin and is detachably connected to the connecting pin; wherein,

[0009] The decorative cover comprises a cover body and a surrounding wall arranged around the cover body, wherein the cover body is connected to a side of the surrounding wall away from the front wheel;

[0010] In the axial direction of the front wheel, one end of the surrounding wall is connected to the cover body, and the other end extends to the outside of the connecting foot, and the surrounding wall is spaced apart from the front wheel;

[0011] The decorative cover comprises an assembly opening, and the assembly opening is used for allowing the front fork leg to pass through when the decorative cover is assembled with the front fork leg.

[0012] The front fork assembly provided in the embodiment of the present application can be conveniently connected to the front wheel by setting a connecting foot at one end of the front fork leg, thereby reducing the difficulty of assembly. By setting a decorative cover, the aesthetics of the front structure of the scooter can be improved. By plugging and matching the decorative cover with the connecting foot, the difficulty of assembly can be reduced and the assembly efficiency can be improved. By detachably connecting the decorative cover with the connecting foot, it is convenient to replace a new decorative cover when the decorative cover is damaged, thereby reducing the maintenance cost. By setting the decorative cover to include a surrounding wall and a cover body, and the cover body is connected to the side of the surrounding wall away from the front wheel, and the surrounding wall is set around the cover body, the decorative cover can be fully wrapped from the front side, the rear side, the bottom side and the outside side to the connection between the connecting foot and the front wheel, thereby preventing the connection between the connecting foot and the front wheel from being hit by sand, gravel, debris, etc. stirred up by the scooter during driving, thereby increasing the service life of the connection between the connecting foot and the front wheel. By setting an assembly port, the decorative cover can be easily assembled, thereby reducing the difficulty of assembly.

[0013] In a possible implementation, a plug-in portion is provided on the inner side of the surrounding wall; wherein,

[0014] The plug-in portion is arranged along the axial direction of the front fork leg, and is used for plugging and matching with the connecting pin when the decorative cover is assembled with the front fork leg.

[0015] The front fork assembly provided in the embodiment of the present application can facilitate the plug-in matching of the decorative cover and the connecting pin by providing a plug-in portion on the surrounding wall of the decorative cover, wherein the plug-in matching generally does not require complicated tools or equipment, and the installation and removal process is relatively simple and quick. The plug-in matching design allows operators to easily assemble and disassemble, reducing the difficulty of operation, so that after the decorative cover is damaged, it can be replaced by oneself, reducing maintenance costs.

[0016] In a possible implementation, the connecting foot includes a matching portion; wherein,

[0017] The matching portion is arranged along the axial direction of the front fork leg, and is used for plugging and matching with the plug-in portion when the decorative cover is assembled with the front fork leg.

[0018] The front fork assembly provided in the embodiment of the present application can be conveniently connected to the decorative cover by providing a matching portion on the connecting foot, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0019] In a possible implementation, the plug-in portion includes a through slot structure extending along the axial direction of the front fork leg; wherein,

[0020] When the decorative cover is assembled with the front fork leg, the matching portion is inserted into the through-slot structure.

[0021] The front fork assembly provided by the embodiment of the present application has a through groove structure in which the insertion part extends along the axial direction of the front insertion leg, which is convenient for assembly, simplifies the structure of the insertion part, further simplifies the structure of the decorative cover, and reduces the processing cost.

[0022] In a possible implementation, the through groove structure includes a first inner wall and a second inner wall; wherein,

[0023] The first inner wall and the second inner wall are arranged opposite to each other along the axial direction of the front wheel;

[0024] At least part of the first inner wall includes an inclined section, and the inclined section gradually inclines towards the side away from the second inner wall along the insertion direction of the decorative cover.

[0025] With such a setting, the opening at one end of the through groove structure facing the insertion direction can be made larger. During assembly, it is convenient for the mating part to be connected to the insertion part, thereby reducing the assembly difficulty. By setting at least part of the first inner wall to include an inclined section, that is to say, a part of the first inner wall is a slope. Since the slope can play a guiding role, it is easier to align and insert during the insertion fit, reducing the installation difficulty. In addition, it can also reduce the possible jamming phenomenon during the insertion process, making the installation process smoother. The slope can remove sharp edges and corners, reducing the risk of injury to the operator during installation and maintenance. The slope can reduce the wear and damage to other components during the insertion process.

[0026] In a possible implementation, the insertion part includes a first baffle and a second baffle arranged opposite to each other along the axial direction of the front wheel; wherein,

[0027] The first baffle and the second baffle are arranged at intervals so as to form the through groove structure between the first baffle and the second baffle.

[0028] With such a setting, the structure of the insertion part can be simplified, the processing difficulty of the decorative cover can be reduced, and the cost can be further reduced.

[0029] In a possible implementation, the surrounding wall of the decorative cover includes a first side wall, a second side wall and a third side wall; wherein,

[0030] The first side wall and the second side wall are arranged opposite to each other in a first direction, the first direction is perpendicular to the axial direction of the front wheel and perpendicular to the axial direction of the front fork leg;

[0031] In the first direction, one end of the third side wall is connected to the first side wall, the other end is connected to the second side wall, and the third side wall is arranged opposite to the assembly port along the axial direction of the front fork leg;

[0032] The insertion part is located on the first side wall and / or the second side wall.

[0033] By arranging the plug-in portion on the first side wall and / or the second side wall, that is, plugging on both sides of the connecting foot, better support can be provided for the decorative cover, thereby improving the stability of the connection, because the plug-in force is distributed on both sides instead of being concentrated on the bottom. This helps to reduce the shaking and tilting of the decorative cover. Plug-in on both sides can effectively improve the torsion resistance of the structure, especially when subjected to lateral forces. In addition, plug-in on both sides can hide the plug-in portion inside or on the side of the structure, making the appearance neater and more beautiful. Plug-in on both sides can distribute stress more evenly, reduce stress concentration points, and thus reduce the risk of material fatigue and damage.

[0034] In a possible implementation, the connecting foot includes a first connecting portion, and the first connecting portion includes a first end wall and a second end wall that are arranged opposite to each other along a first direction; wherein,

[0035] The first end wall and the second end wall are the matching parts.

[0036] Such arrangement can simplify the structure of the connecting foot and the matching part, thereby reducing the cost. In addition, the matching part is the first end wall and the second end wall of the first connecting part, so that the first connecting part can be an integrated structure, which can simplify the structure of the first connecting part and improve the structural strength of the first connecting part.

[0037] In a possible implementation, in the axial direction of the front fork leg, a first retracted portion is provided at one end of the first end wall away from the front fork leg, and a second retracted portion is provided at one end of the second end wall away from the front fork leg;

[0038] The first retracted portion and the second retracted portion are gradually inclined toward each other along a direction opposite to the insertion direction of the decorative cover.

[0039] With such arrangement, the dimension of the first connection part in the first direction at the end away from the front fork leg can be smaller than the dimension of the first connection part in the first direction at the end away from the front fork leg, that is, the dimension of the end of the first connection part close to the ground is smaller, so that when the decorative cover is plugged and matched with the first connection part, collision can be avoided, which facilitates assembly and reduces assembly difficulty. In addition, the material used for the connecting foot can be reduced, thereby reducing costs.

[0040] For example, a second connection portion may be provided at one end of the first connection portion away from the front fork leg, and the second connection portion is used to be fixedly connected to the third side wall. By gradually tilting the first retracted portion and the second retracted portion toward each other in the opposite direction of the decorative cover insertion direction, the size of the second connection portion in the first direction is reduced, and the material used for the connection foot is further reduced, thereby reducing the cost. In addition, a smaller second connection portion can facilitate the miniaturization of the bottom of the decorative cover.

[0041] In a possible implementation, an end of the first retracted portion close to the front fork leg and an end of the second retracted portion close to the front fork leg are both provided with a chamfered structure.

[0042] It should be noted that "chamfering" refers to beveling or rounding the edge or corner of a workpiece, usually cutting at a certain angle or radius. By providing a chamfered structure at one end of the first retracted portion close to the front fork leg and one end of the second retracted portion close to the front fork leg, it can guide the assembly of the decorative cover and the connecting foot, making it easier to align and insert the plug-in portion of the decorative cover, reducing the difficulty of installation. The chamfered structure can reduce the jamming phenomenon that may occur during the plug-in process, making the installation process smoother. It can also effectively disperse stress and reduce stress concentration points, thereby reducing the risk of material fatigue and fracture. By reducing stress concentration, the strength and durability of the overall structure can be improved. The chamfered structure can remove sharp edges and corners, reducing the risk of injury to operators during installation and maintenance. It can also reduce wear and damage to other components during the plug-in process.

[0043] In a possible implementation, the first connection portion includes a first connection hole; wherein,

[0044] The first connecting hole is used to connect with the front wheel.

[0045] By providing the first connecting hole, it is possible to facilitate connection with the front wheel, for example, it can be connected via a fastener, which can reduce the difficulty of assembly.

[0046] In a possible implementation, the connecting foot includes a second connecting portion; wherein,

[0047] In the axial direction of the front fork leg, the second connecting portion is connected to an end of the first connecting portion which is away from the front fork leg;

[0048] The second connecting portion is used for fixedly connecting to the third side wall.

[0049] By providing the second connection part and connecting the second connection part to the third side wall, the connection stability between the decorative cover and the connection foot can be increased, thereby preventing the decorative cover from falling off and extending the service life of the decorative cover.

[0050] In a possible implementation, a second connection hole is provided on the second connection portion;

[0051] The third side wall is provided with a third connection hole corresponding to the second connection hole;

[0052] The second connecting hole and the third connecting hole are connected by a fastener.

[0053] By providing a second connection hole on the second connection part and a third connection hole on the third side wall, and connecting them with fasteners, the fasteners can provide a firm connection, capable of withstanding large mechanical stresses and loads, improving the anti-vibration and anti-impact capabilities of the connection, and ensuring the stability and reliability of the connection. Additionally, the components can be easily disassembled and reassembled, facilitating maintenance and repair. Removing the fasteners is simpler and quicker than welding or adhesive bonding. Fastener connections can be applied to various materials, including metals, plastics, wood, etc., with strong adaptability. This connection method is suitable for a variety of structural forms and design requirements, offering great flexibility. Fasteners usually have a relatively low cost, and the installation process does not require complex equipment and processes, reducing the manufacturing cost. The installation process of fastener connections is relatively simple and fast, significantly reducing the installation time and improving production efficiency. Through the design of through holes and fasteners, high-precision positioning and connection can be achieved, ensuring the relative positions and functions of the components. Additionally, fastener connections have high repeatability. After each disassembly and reassembly, the positions and performances of the components basically remain the same.

[0054] In a possible implementation, the orthographic projection of the second connection hole on the third side wall is located within the third connection hole.

[0055] With such a setting, the size of the third connection hole can be made larger. In this way, the third connection hole can provide a larger tolerance range, making it easier for the fasteners to be aligned and inserted, and reducing the assembly difficulty. Since the third connection hole provides more space, the fasteners can be inserted and fixed more quickly, thereby reducing the installation time and improving production efficiency. The larger third connection hole can avoid forced fitting, reducing the stress and damage to the second connection part during the assembly process. Furthermore, it reduces the deformation of the decorative cover and the connection leg during the assembly process, maintaining the shape and size stability of the second connection hole. The larger third connection hole can compensate for the errors generated during the manufacturing process. Even if there are certain deviations in the position or size of the second connection hole, it can ensure that the fasteners can be installed smoothly. The larger third connection hole can increase the tolerance range, making the manufacturing and assembly of the connection leg more flexible and forgiving.

[0056] In a possible implementation, the third connection hole is an oval hole, a round hole, or a special-shaped hole.

[0057] With such a setting, the processing difficulty of the third connection hole can be reduced, and the design flexibility of the third connection hole can be improved.

[0058] In a possible implementation, one end of the cover body close to the assembly port is provided with an inclined surface; wherein,

[0059] The inclined surface slopes gradually away from the front fork leg in the insertion direction of the decorative cover.

[0060] By providing an inclined surface at one end of the cover body close to the assembly port, since the inclined surface can play a guiding role, it is easier to align and insert during the plug-in fit, reducing the installation difficulty. Additionally, by inclining the inclined surface in the plug-in direction of the decorative cover gradually away from the front fork leg, the end of the cover body close to the assembly port can be farther away from the connecting feet, preventing the outer paint of the front fork leg from being scratched during assembly and causing the front fork leg to rust easily. The inclined surface can remove sharp edges and corners, reducing the risk of injury to the operator during installation and maintenance.

[0061] In a possible implementation, the decorative cover is a plastic cover.

[0062] By setting the decorative cover as a plastic cover, compared with metal parts, the plastic cover is lighter, which helps to reduce the overall weight of the scooter, improve the riding efficiency and comfort. A lighter scooter is easier to carry and handle, especially in cases where it needs to be carried up and down stairs or loaded onto a vehicle. Plastic materials are usually cheaper than metal materials, and the processing technology is relatively simple, which can reduce the manufacturing cost. Plastic parts are not easy to rust and corrode, reducing the frequency of maintenance and replacement, thus reducing the long-term use cost. Plastic materials have strong plasticity and can be manufactured into complex shapes and structures through processes such as injection molding and extrusion to meet diverse design requirements. Plastic materials are usually softer, and the edges can be designed to be more rounded, reducing the risk of injury to the rider. High-quality plastic materials have good toughness and are not easy to break, reducing the danger during collisions or falls.

[0063] In the second aspect of the embodiments of the present application, a scooter is provided, including the front fork assembly according to any one of the first aspects above.

[0064] For the scooter provided by the embodiments of the present application, by providing the above-mentioned front fork assembly, it is possible to prevent the gravel, debris, etc. stirred up during the driving of the scooter from hitting the connection between the front wheel and the front fork, and extend the service life of the connection between the front wheel and the front fork.

[0111] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0112] A scooter is a convenient, environmentally friendly and economical means of transportation, suitable for people of all ages. Whether it is a manual scooter or an electric scooter, each has its unique advantages and application scenarios.

[0113] As Figure 1 shown, the scooter 1000 includes a handlebar 220, an upright pipe assembly 210, a front fork assembly 100, wheels 300 and a frame 410. Among them, the wheels 300 include a front wheel 310 and a rear wheel 320, and the front wheel 310 and the rear wheel 320 are respectively arranged at the front end and the rear end of the frame 410.

[0114] The frame 410 is connected to the front wheel 310 through the front fork assembly 100, and the frame 410 is connected to the rear wheel 320 through the swing arm 500 to connect the various components of the scooter 1000 into an integrated structure. Among them, the upper surface of the frame 410 is for the user to stand on and is usually made of a strong material (such as aluminum alloy or composite material) with a non-slip surface. A side stand can be provided on one side of the frame 410 to support the scooter 1000 when not in use.

[0115] The riser assembly 210 is used to connect the handlebar 220 and the front fork assembly 100 and can usually be adjusted in height to accommodate users of different heights. The handlebar 220 is the gripping part of the scooter 1000 and is usually made of rubber or foam material to provide a comfortable grip and anti-slip effect.

[0116] The front fork assembly 100 is the part connecting the riser assembly 210 and the front wheel 310 and is usually made of metal (such as aluminum alloy or steel) with high strength and durability. In the embodiments of the present application, the material of the front fork assembly 100 is not further limited.

[0117] The structure of the front fork assembly 100 will be further described below with reference to the drawings.

[0118] An embodiment of the present application provides a front fork assembly 100, as Figure 2 shown, the front fork assembly 100 may include a front fork tube 10, a front fork yoke 20, and two front fork legs 30. The two front fork legs 30 are disposed opposite to each other on both sides of the front wheel 310. One end of the front fork leg 30 facing away from the front wheel 310 is connected to the front fork yoke 20. At least part of the structure of the front fork tube 10 is disposed on the side of the front fork yoke 20 facing away from the front wheel 310, and in the axial direction of the front wheel 310, the central axis of the front fork tube 10 is located on the central axis n of the front fork yoke 20 (see Figure 4 shown).

[0119] It should be noted that the direction where the central axis of the front fork yoke 20 is located is the first direction, which is represented as the x direction in the figure. The axial direction of the wheel 300 (including the front wheel 310 and the rear wheel 320) is represented as the y direction in the figure, and the axial directions of the front fork leg 30 and the front fork tube 10 are both represented as the z direction.

[0120] It should be noted that in the embodiments of the present application, "facing away from" refers to a broad sense of facing away from, not limited to being parallel and opposite back to back.

[0121] In a possible implementation, as Figure 3As shown, the front fork leg 30 includes a support rod 31, a shock absorber cylinder 32, and a shock absorber 33. Among them, in the axial direction of the front fork leg 30, one end of the support rod 31 is connected to the front fork connecting plate 20, and the other end is movably connected to the shock absorber cylinder 32. The shock absorber 33 is located inside the shock absorber cylinder 32. In the axial direction of the front fork leg 30, the shock absorber 33 is elastic, and one end of the shock absorber 33 is connected to the shock absorber cylinder 32, and the other end is connected to the support rod 31. The end of the shock absorber cylinder 32 facing away from the support rod 31 is used to connect to the front wheel 310. The distance between the bottom surface of the first mounting hole 22b provided on the bottom wall 27 of the front fork connecting plate 20 and the top surface of the shock absorber cylinder 32 is the maximum shock absorption stroke h of the shock absorber 33 (see Figure 6 as shown).

[0122] The front fork leg 30 includes a support rod 31, a shock absorber cylinder 32, and a shock absorber 33. During the driving of the vehicle, the interaction of the three can endow the front fork leg 30 with a shock absorption function, effectively absorbing the impacts and vibrations from road unevenness, potholes, and obstacles, reducing the impact loads transmitted to the frame 410 and the rider, thereby improving the riding comfort. At the same time, it can help maintain the continuous contact of the front wheel 310 with the ground, providing better grip and stability, especially when turning, braking, and passing through uneven roads, improving the handling performance of the scooter 1000. Exemplarily, the shock absorber 33 can be a spring shock absorber 33, a hydraulic shock absorber 33, or a pneumatic shock absorber 33. By arranging the shock absorber 33 inside the shock absorber cylinder 32, the shock absorber 33 can be hidden inside the shock absorber cylinder 32, preventing damage from dirt, stones, and other sundries.

[0123] In a possible implementation manner, the support rod 31 is in plug-in fit with the shock absorber cylinder 32.

[0124] By plugging the support rod 31 into the shock absorber cylinder 32, the assembly difficulty of the support rod 31 and the shock absorber cylinder 32 can be reduced, the manufacturing complexity and cost can be reduced, and the production efficiency can be improved. It can also effectively absorb and buffer the vibrations and impacts from the road surface, reduce the vibrations transmitted to the frame 410 and the rider, improve the riding comfort, improve the riding stability, and facilitate maintenance and replacement.

[0125] It should be noted that the shock absorption stroke of the front fork assembly 100 will directly affect the shock absorption effect of the scooter 1000. In order to increase the shock absorption stroke of the front fork assembly 100 of the scooter 1000, an embodiment of the present application provides a front fork connecting plate 20. The following will describe the front fork connecting plate 20 in the embodiment of the present application in detail with reference to the accompanying drawings.

[0126] An embodiment of the present application provides a front fork connecting plate 20, as Figure 4As shown, the front fork connecting plate 20 includes a connecting plate body 21. Two first mounting portions 22 and a second mounting hole 23 are provided on the connecting plate body 21. The two first mounting portions 22 are symmetrically arranged on the connecting plate body 21 along the central axis n of the connecting plate body 21.

[0127] Exemplarily, when the front fork connecting plate 20 is assembled to the scooter 1000, the two first mounting holes 22b are oppositely arranged at both ends of the connecting plate body 21 along the axial direction (y direction) of the front wheel 310. And they are symmetrically arranged with respect to the central axis n of the connecting plate body 21.

[0128] As Figure 5 shown, the first mounting portion 22 includes a first mounting hole 22b and a mounting surface 22a. The first mounting hole 22b is used for fitting connection with the front fork leg 30, and the mounting surface 22a is used for abutting against the top surface of the front fork leg 30 when assembled with the front fork leg 30. The second mounting hole 23 is located between the two first mounting holes 22b, and the center of the second mounting hole 23 is located on the central axis of the connecting plate body 21. The second mounting hole 23 is used for fitting connection with the front fork tube 10.

[0129] It should be noted that, as shown in FIG. 4, in the y direction, the second mounting hole 23 is located between the two first mounting holes 22b, and the central axis n of the front fork connecting plate 20 is parallel to the x direction (the first direction).

[0130] Combined with Figure 5 and Figure 6 shown, define the projection plane perpendicular to the central axis of the connecting plate body 21 as the first projection plane. The positive projection of the central axis of the second mounting hole 23 on the first projection plane is the first projection line e, and the positive projection of the straight line where the top surface of the connecting plate body 21 is located on the first projection plane is the second projection line m. The intersection point of the first projection line e and the second projection line m is the first intersection point 24. The positive projection of the central axis of the first mounting hole 22b on the first projection plane is the third projection line f, and the positive projection of the straight line where the mounting surface 22a is located on the first projection plane is the fourth projection line g. The intersection point of the third projection line f and the fourth projection line g is the second intersection point 25. Define the connecting line between the first intersection point 24 and the second intersection point 25 as the first straight line p. The acute angle a formed between the first straight line p and the second projection line m is greater than or equal to 0° and less than or equal to 10°.

[0131] In the embodiment of the present application, the front fork connecting plate 20 is provided with two first mounting portions 22 symmetrically arranged along the central axis n of the connecting plate body 21. The second mounting hole 23 is arranged between the two first mounting holes 22b, and the center of the second mounting hole 23 is located on the central axis n of the connecting plate body 21. In this way, the structure of the front fork connecting plate 20 can be made more symmetrical, the stress and load can be evenly distributed, and the stability and strength of the overall structure can be improved. The symmetrically designed front fork connecting plate 20 ensures that the front fork legs 30 are evenly distributed on both sides of the front wheel 310, providing better balance and stability, especially during turning and braking, and enhancing the handling performance. The symmetric design can effectively disperse and evenly distribute the stress between the front fork connecting plate 20 and the front fork legs 30, reduce the phenomenon of local stress concentration, and extend the service life of the front fork assembly 100. In addition, by arranging the first mounting portion 22 to include the first mounting hole 22b and the mounting surface 22a, it is convenient to plug and cooperate with the front fork legs 30 of the front fork assembly 100 and abut against them, improving the connection stability between the front fork legs 30 and the front fork connecting plate 20. By providing the second mounting hole 23, it is convenient to connect with the front fork legs 30 and the front fork tube 10, improving the stability of the front fork assembly 100.

[0132] It is set to be greater than or equal to 0 and less than or equal to 10° through the acute angle a formed between the first straight line p and the second projection line m. In this way, the distance k between the connection surface of the front fork tube 10 and the front fork connecting plate 20 and the connection surface of the front fork leg 30 and the front fork connecting plate 20 can be reduced, that is, the distance k from the second projection line m to the fourth projection line g, thereby reducing the influence of the structure of the front fork connecting plate 20 itself on the shock absorption stroke.

[0133] Compared with the related art, such as Figure 7 As shown, for the V-shaped structure with the opening of the front fork connecting plate 20 facing downward, the technical solution of the present application can translate the connection surface (this connection surface is the mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20 upward, releasing the space below the connection surface (mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20, thereby providing a setting space for increasing the shock absorption stroke. In this way, the scooter 1000 using this front fork connecting plate 20 can have a larger shock absorption stroke, and thus has a better shock absorption effect, and this will not increase the height of the front fork tube 10, making the packaging of the scooter 1000 smaller and reducing the packaging cost.

[0134] In a possible implementation manner, on the first projection plane, the acute angle a formed between the first straight line p and the second projection line m is greater than or equal to 0 and less than or equal to 5°.

[0135] With such a setting, the distance k from the connection surface between the front fork tube 10 and the front fork yoke plate 20 to the connection surface between the front fork leg 30 and the front fork yoke plate 20 can be further reduced, thereby reducing the influence of the structure of the front fork yoke plate 20 itself on the shock absorption stroke. Compared with the "V" - shaped structure with the opening of the front fork yoke plate 20 facing downward in the related art, the technical solution of the present application can translate the connection surface (mounting surface 22a) between the front fork leg 30 and the front fork yoke plate 20 upward, further releasing the space below the connection surface (mounting surface 22a) between the front fork leg 30 and the front fork yoke plate 20, thereby providing a setting space for increasing the shock absorption stroke. In this way, the scooter 1000 using this front fork yoke plate 20 can have a larger shock absorption stroke, and thus has a better shock absorption effect. And this will not increase the height of the front fork tube 10, making the package of the scooter 1000 smaller and reducing the packaging cost.

[0136] Exemplarily, on the first projection plane, the acute angle a formed between the first straight line p and the second projection line m can be 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, etc. In the embodiments of the present application, on the first projection plane, the acute angle a formed between the first straight line p and the second projection line m is not further limited.

[0137] It should be noted that when the front fork yoke plate 20 is assembled on the front fork assembly 100 of the scooter 1000, when the acute angle a formed between the first straight line p and the second projection line m on the first projection plane is 0°, the second projection line m and the mounting surface 22a are in the same plane. When the acute angle a formed between the first straight line p and the second projection line m is greater than 0°, the mounting surface 22a can be above the second projection line m or below the second projection line m. In the embodiments of the present application, the positional relationship between the mounting surface 22a and the second projection line m is not further limited. In addition, to ensure the strength of the front fork yoke plate 20, the front fork yoke plate 20 usually requires a certain thickness. The technical solution in the embodiments of the present application can ensure the structural strength of the front fork yoke plate 20 and can also provide a larger space for extending the shock absorption stroke.

[0138] In a possible implementation manner, as Figure 8 shown, when the front fork yoke plate 20 is assembled onto the front fork assembly 100, the center of the second mounting hole 23 is closer to the rear wheel 320 relative to the center of the first mounting hole 22b.

[0139] As Figure 9 shown, the distance L from the central axis of the second mounting hole 23 to the plane where the central axes of the two first mounting holes 22b are located is greater than or equal to 10 millimeters and less than or equal to 35 millimeters.

[0140] In the front fork connecting plate 20 in the embodiment of the present application, by making the center of the second mounting hole 23 closer to the rear wheel 320 than the center of the first mounting hole 22b, and setting the distance L from the central axis of the second mounting hole 23 to the plane where the central axes of the two first mounting holes 22b are located to be greater than or equal to 10 mm and less than or equal to 35 mm, the front fork leg 30 can be made to be away from the rear wheel 320, while the front fork tube 10 is closer to the rear wheel 320. In this way, the axial length of the front fork tube 10 can be shortened, the swing amplitude during steering can be reduced, the accuracy and response speed of steering can be improved, the handling performance can be enhanced, and the center of gravity of the scooter 1000 can also be lowered, making the vehicle more stable, especially during high-speed driving and turning, reducing the risk of rollover and improving riding safety. In addition, it can prevent the front wheel 310 from colliding with the frame 410 of the scooter 1000 during steering, improving the installation performance.

[0141] In a possible implementation manner, the distance L from the central axis of the second mounting hole 23 to the plane where the central axes of the two first mounting holes 22b are located is greater than or equal to 10 mm and less than or equal to 20 mm.

[0142] With such a setting, the size of the front fork connecting plate 20 can be reduced, making the structure of the front fork assembly 100 more compact, which is beneficial to the miniaturization development of the scooter 1000.

[0143] Exemplarily, the distance L from the central axis of the second mounting hole 23 to the plane where the central axes of the two first mounting holes 22b are located can be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 22 mm, 24 mm, 26 mm, 28 mm, 30 mm, 32 mm, 33 mm, 35 mm, etc. In the embodiment of the present application, the distance L from the central axis of the second mounting hole 23 to the plane where the central axes of the two first mounting holes 22b are located is not further limited, and can be specifically set according to the specific size of the scooter 1000.

[0144] Continue to refer to Figure 5 As shown, the connecting plate body 21 can be a shell wall structure with an internal cavity. Among them, the shell wall structure includes a top wall 26 and a bottom wall 27 that are relatively spaced apart. The first mounting hole 22b and the second mounting hole 23 both penetrate through the top wall 26 and the bottom wall 27. Among them, the position where the second mounting hole 23 is provided protrudes along the first direction (x direction), so that the central axes of the first mounting hole 22b and the second mounting hole 23 are not in the same plane.

[0145] In the embodiment of the present application, for the front fork connecting plate 20, by setting the connecting plate body 21 as a housing wall structure with an internal cavity, the weight of the connecting plate body 21 can be significantly reduced, thereby reducing the weight of the entire scooter 1000 and improving the riding efficiency and convenience. The housing wall structure with an internal cavity has certain elasticity and buffering ability, which can effectively absorb and disperse the vibration and impact from the road surface, reduce the influence on the vehicle frame 410 and the rider, and improve the riding comfort. The housing wall structure with an internal cavity can be formed in various ways, such as casting, stamping, 3D printing, etc., which can reduce the manufacturing difficulty and cost and improve the production efficiency. By setting the first mounting hole 22b and the second mounting hole 23 to penetrate both the top wall 26 and the bottom wall 27, the connection stability of the first mounting hole 22b and the second mounting hole 23 can be improved.

[0146] Exemplarily, the bottom wall 27 is provided with a slit structure 271, and the slit structure 271 extends from the first mounting hole 22b to the second mounting hole 23. Among them, there are two slit structures 271, which are respectively arranged on both sides of the second mounting hole 23.

[0147] In the embodiment of the present application, for the front fork connecting plate 20, by setting the slit structure 271 on the bottom wall 27, the first mounting hole 22b or the second mounting hole 23 can generate certain elastic deformation when bolts and other connecting parts are tightened, thereby enhancing the clamping force, ensuring the tight connection between the front fork leg 30 or the front fork tube 10 and the front fork connecting plate 20, and preventing loosening. The slit design can help disperse and reduce the stress concentration around the first mounting hole 22b and the second mounting hole 23, reduce the material fatigue and damage caused by stress concentration, and improve the service life of the front fork connecting plate 20 and the front fork assembly 100 using the front fork connecting plate 20.

[0148] The slit design makes the front fork leg 30 and the front fork tube 10 more flexible during the installation and adjustment process, facilitating alignment and positioning, and ensuring the precise fit between the front fork leg 30 and the front fork tube 10 and the front fork connecting plate 20. The slit design can provide certain elastic buffering, absorb the vibration and impact generated during riding, reduce the damage to the front fork assembly 100, and improve the riding comfort. The slit design can adapt to manufacturing tolerances within a certain range, ensure the reliable connection between the front fork leg 30, the front fork tube 10 and the front fork connecting plate 20, and reduce the assembly problems caused by manufacturing errors. The slit design can reduce the weight of the front fork connecting plate 20 without significantly affecting the strength, contribute to the lightweight design of the overall scooter 1000, and improve the riding performance.

[0149] It should be noted that the shapes of the two slit structures 271 can be the same or different. In addition, the two slit structures 271 can be symmetrically arranged on both sides of the second mounting hole 23 or asymmetrically arranged. In the embodiment of the present application, the shape and the setting position of the slit structure 271 are not further limited.

[0150] Continue to see Figure 5 As shown, the top wall 26 of the connecting plate body 21 may include a convex structure 261. The convex structure 261 is arranged around the first mounting hole 22b, and a side of the convex structure 261 facing the bottom wall 27 is a mounting surface 22a.

[0151] It should be noted that in the embodiments of the present application, "orientation" refers to orientation in a broad sense and is not limited to face-to-face orientation.

[0152] In some embodiments, the front fork leg 30 can be fixedly connected to the front fork link plate 20 by fasteners, such as screws, bolts, etc., wherein the screw includes a screw head, and the bolt includes a bolt head. By providing a convex edge structure 261, the first mounting hole 22b can be located at a portion of the top wall 26 with a smaller opening, so as to provide a support position for the fastener so as to be fixedly connected with the fastener. In addition, a mounting surface 22a can be formed on a side of the convex edge structure 261 facing the bottom wall 27 to form a support with the front fork leg 30, so as to be fixedly connected with the front fork leg 30. By providing the convex edge structure 261 on the top wall 26, the distance between the connection surface of the front fork link plate 20 and the front fork tube 10 and the mounting surface 22a between the front fork leg 30 and the front fork link plate 20 can be reduced, thereby reducing the influence of the structure of the front fork link plate 20 itself on the shock absorbing stroke. In addition, the convex edge structure 261 is easy to process, which can reduce the processing difficulty of the front fork link plate 20, thereby reducing the cost.

[0153] Exemplarily, the first mounting hole 22b and the second mounting hole 23 can both be countersunk structures on the top wall 26 of the connecting plate body 21. By setting the first mounting hole 22b and the second mounting hole 23 on the top wall 26 of the connecting plate body 21 as countersunk structures, fasteners connected to the front fork leg 30, such as screw heads and bolt heads, can be hidden below the top surface of the top wall 26, making the surface smoother and more beautiful, and avoiding the exposure of the screw heads. Hiding the screw heads can reduce protrusions on the surface, avoid scratching or hooking other items, and improve safety and aesthetics. The countersunk holes can provide additional support to prevent the screws from loosening in a vibration or impact environment, thereby improving the reliability of the connection.

[0154] Continue to see Figure 6 As shown, when the front fork link plate 20 is assembled to the front fork assembly 100, the two front fork legs 30 are arranged opposite to each other at the two ends of the front fork link plate 20, and the two front fork legs 30 are respectively connected with the two first mounting holes 22b. The front fork tube 10 is located on the side of the front fork link plate 20 away from the front fork legs 30, and is connected with the second mounting hole 23.

[0155] The front fork assembly 100 provided by the embodiment of the present application can reduce the distance from the connection surface between the front fork connecting plate 20 and the front fork tube 10 to the connection surface (mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20 by setting the above-mentioned front fork connecting plate 20, thereby reducing the influence of the structure of the front fork connecting plate 20 itself on the shock absorption stroke. Compared with the related art in which the front fork connecting plate 20 is set in a V-shaped structure with the opening facing downwards, the technical solution of the present application can translate the connection surface (mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20 upwards, releasing the space below the connection surface (mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20, thereby providing a setting space for increasing the shock absorption stroke. In this way, the scooter 1000 using this front fork connecting plate 20 can have a larger shock absorption stroke, and thus has a better shock absorption effect. Moreover, this does not increase the height of the front fork tube 10, making the package of the scooter 1000 smaller and reducing the packaging cost.

[0156] When the scooter 1000 is provided with the front fork connecting plate 20 in the above-mentioned embodiment, it can also reduce the distance from the connection surface between the front fork connecting plate 20 and the front fork tube 10 to the connection surface (mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20, thereby reducing the influence of the structure of the front fork connecting plate 20 itself on the shock absorption stroke. Compared with the related art in which the front fork connecting plate 20 is set in a V-shaped structure with the opening facing downwards, the technical solution of the present application can translate the connection surface (mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20 upwards, releasing the space below the connection surface (mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20, thereby providing a setting space for increasing the shock absorption stroke. In this way, the scooter 1000 using this front fork connecting plate 20 can have a larger shock absorption stroke, and thus has a better shock absorption effect. Moreover, this does not increase the height of the front fork tube 10, making the package of the scooter 1000 smaller and reducing the packaging cost.

[0157] It should be noted that if the position where the front fork leg 30 is connected to the front wheel 310 is exposed to the air, sand, debris, etc. stirred up by the scooter 1000 during driving are likely to impact the connection between the front wheel 310 and the front fork, thereby causing the problem that the connection between the front wheel 310 and the front fork is easily damaged.

[0158] Therefore, the embodiment of the present application also provides a front fork assembly 100. By setting a decorative cover 40 at the connection between the front fork leg 30 and the front wheel 310, it is possible to prevent sand, debris, etc. stirred up by the scooter 1000 during driving from impacting the connection between the front wheel 310 and the front fork, and extend the service life of the connection between the front wheel 310 and the front fork.

[0159] The following describes the front fork assembly 100 in the embodiment of the present application with reference to the drawings.

[0160] The embodiment of the present application also provides a front fork assembly 100, such asFigure 10 As shown, the front fork assembly 100 may include front fork legs 30 and a decorative cover 40. One end of the front fork leg 30 is provided with a connecting foot 34, and the connecting foot 34 is used to connect with the front wheel 310.

[0161] In the embodiment of the present application, the decorative cover 40 is inserted and matched with the connecting foot 34 and is detachably connected to the connecting foot 34. The decorative cover 40 may include a cover body 41 and a surrounding wall 42 arranged around the cover body 41, and the cover body 41 is connected to the side of the surrounding wall 42 facing away from the front wheel 310.

[0162] In the axial direction (y direction) of the front wheel, one end of the surrounding wall 42 is connected to the cover body 41, and the other end extends to the outside of the connecting foot 34, and the surrounding wall 42 is spaced from the front wheel 310. The surrounding wall 42 includes an assembly opening 43, and the assembly opening 43 is used for the front fork leg 30 to pass through when the decorative cover 40 is assembled with the front fork leg 30.

[0163] It should be noted that in the axial direction (y direction) of the front wheel, one end of the surrounding wall 42 is connected to the cover body 41, the other end extends to the outside of the connecting foot 34, and the surrounding wall 42 is spaced from the front wheel 310, which means that the positive projection of the surrounding wall 42 in the axial direction (y direction) of the front wheel can cover the connecting foot 34, and there is no interference problem between the surrounding wall 42 and the front wheel 310.

[0164] It should be noted that when the decorative cover 40 is inserted and matched with the connecting foot 34, the decorative cover 40 can be inserted and matched with the connecting foot 34 along the axial direction of the front fork leg 30 from bottom to top. As Figure 10 shown, the insertion direction is the direction indicated by the dotted line with an arrow. The direction away from the insertion direction is the opposite direction of the insertion direction.

[0165] In the front fork assembly 100 provided in the embodiment of the present application, by providing the connecting foot 34 at one end of the front fork leg 30, it is convenient to connect with the front wheel 310 and reduce the assembly difficulty. By providing the decorative cover 40, the aesthetics of the front structure of the scooter 1000 can be improved. By inserting and matching the decorative cover 40 with the connecting foot 34, the assembly difficulty can be reduced and the assembly efficiency can be improved. By detachably connecting the decorative cover 40 with the connecting foot 34, when the decorative cover 40 is damaged, it is convenient to replace the new decorative cover 40, and the maintenance cost can be reduced.

[0166] By providing a decorative cover 40 including a surrounding wall 42 and a cover body 41, with the cover body 41 connected to the side of the surrounding wall 42 facing away from the front wheel 310 and the surrounding wall 42 disposed around the cover body 41, the decorative cover 40 can comprehensively wrap the connection between the connecting leg 34 and the front wheel 310 from the front side, rear side, bottom side, and outer side, preventing the connection between the connecting leg 34 and the front wheel 310 from being impacted by gravel, debris, etc. stirred up by the scooter 1000 during driving, and improving the service life of the connection between the connecting leg 34 and the front wheel 310. By providing an assembly port 43, it is convenient to assemble the decorative cover 40 and reduce the assembly difficulty.

[0167] In a possible implementation, as Figure 11 shown, a plug-in portion 424 is provided on the inner side of the surrounding wall 42. The plug-in portion 424 is arranged along the axial direction (z direction) of the front fork leg 30, and the plug-in portion 424 is used for plugging and cooperating with the connecting leg 34 when the decorative cover 40 is assembled with the front fork leg 30. Correspondingly, the connecting leg 34 includes a cooperating portion 342. The cooperating portion 342 is arranged along the axial direction of the front fork leg 30, and the cooperating portion 342 is used for plugging and cooperating with the plug-in portion 424 when the decorative cover 40 is assembled with the front fork leg 30.

[0168] For the front fork assembly 100 provided by the embodiments of the present application, by providing a plug-in portion 424 on the surrounding wall 42 of the decorative cover 40, it is convenient for the decorative cover 40 to be plugged and cooperated with the connecting leg 34. Usually, plugging and cooperation do not require complex tools or equipment, and the installation and disassembly processes are relatively simple and fast. The design of plugging and cooperation enables the operator to easily assemble and disassemble, reducing the operation difficulty. In this way, after the decorative cover 40 is damaged, it can be replaced by itself, reducing the maintenance cost.

[0169] In some embodiments, the plug-in portion 424 may include a through groove structure extending along the axial direction (z direction) of the front fork leg 30. When the decorative cover 40 is assembled with the front fork leg 30, the cooperating portion 342 is plugged into the through groove structure to limit the decorative cover 40, preventing the decorative cover 40 from loosening and displacing unexpectedly in the axial direction of the front wheel shaft 50, and improving the reliability of the assembly.

[0170] As Figure 12 shown, the surrounding wall 42 of the decorative cover 40 may include a first side wall 421, a second side wall 422, and a third side wall 423. Among them, the first side wall 421 and the second side wall 422 are oppositely arranged along a first direction (x direction). The first direction is perpendicular to the axial direction of the front wheel 310 and perpendicular to the axial direction of the front fork leg 30. In the first direction, one end of the third side wall 423 is connected to the first side wall 421, the other end is connected to the second side wall 422, and the third side wall 423 and the assembly port 43 are oppositely arranged along the axial direction of the front fork leg 30. The plug-in portion 424 is located on the first side wall 421 and / or the second side wall 422.

[0171] Exemplarily, the number of the insertion parts 424 can be one, and the insertion part 424 can be arranged on the first side wall 421 or the second side wall 422. Alternatively, the number of the insertion parts 424 is two, and the two insertion parts 424 are respectively arranged on the first side wall 421 and the second side wall 422. Moreover, the two insertion parts 424 are arranged oppositely along the first direction so as to be inserted and matched with the connection pins 34.

[0172] By arranging the insertion part 424 on the first side wall 421 and / or the second side wall 422, that is to say, inserting on both sides of the connection pin 34, better support can be provided for the decorative cover 40 in this way, thereby improving the connection stability. Because the insertion force is distributed on two sides instead of concentrated at the bottom. This helps to reduce the shaking and tilting of the decorative cover 40. Inserting on both sides can effectively improve the anti-torsion ability of the structure, especially perform better when bearing lateral forces. In addition, inserting on both sides can hide the insertion part 424 inside the structure or on the side, making the appearance cleaner and more beautiful. Inserting on both sides can distribute the stress more evenly, reduce the stress concentration points, and thus reduce the risk of material fatigue and damage.

[0173] In some embodiments, the surrounding wall 42 of the decorative cover 40 can be generally in a "U" - shaped structure. The opening of the "U" - shaped structure is the assembly opening 43, and the opening of the "U" - shaped structure faces upward. Here, upward refers to the direction away from the ground. Of course, the bottom surface of the "U" - shaped structure, that is, the third side wall 423 can be an arc - shaped wall structure, which can reduce stress concentration and can improve the appearance aesthetic feeling. Of course, in some other embodiments, the third side wall 423 can also be a straight - line - shaped wall structure. In the embodiments of the present application, the shape of the third side wall 423 is not further limited.

[0174] As Figure 12 shown, the insertion part 424 can include a first baffle 4241 and a second baffle 4242 which are arranged oppositely along the front wheel axis 50 (y - direction). Wherein, the first baffle 4241 and the second baffle 4242 are arranged at intervals so as to form a through - slot structure between the first baffle 4241 and the second baffle 4242. Arranged in this way, the structure of the insertion part 424 can be simplified, the processing difficulty of the decorative cover 40 can be reduced, and thus the cost can be reduced.

[0175] Exemplarily, the first baffle 4241 and the second baffle 4242 can be fixed on the first side wall 421 and the second side wall 422 by integral molding, welding, bonding and other methods, which can improve the connection stability between the first baffle 4241 and the second baffle 4242 and the first side wall 421 and the second side wall 422. In the embodiments of the present application, the connection manner between the first baffle 4241 and the second baffle 4242 and the first side wall 421 and the second side wall 422 is not further limited.

[0176] Of course, in some other embodiments, the through groove structure may also be a groove structure formed on the first side wall 421 and the second side wall 422. In the embodiments of the present application, the setting manner of the through groove structure is not further limited.

[0177] In a possible implementation, as Figure 13 shown, the through groove structure may include a first inner wall 424a and a second inner wall 424b. The first inner wall 424a and the second inner wall 424b are oppositely arranged along the front wheel axle 50 in the y direction. At least a part of the first inner wall 424a includes an inclined section (not labeled in the figure), Figure 13 and a part of the structure of the upper part of the first inner wall 424a in the figure is an inclined section. Among them, the inclined section gradually inclines towards the side away from the second inner wall 424b along the insertion direction of the decorative cover 40. That is to say, the opening at the end of the through groove structure away from the ground is larger.

[0178] Of course, in other embodiments, an inclined section may also be provided on the second inner wall 424b, and the inclined section on the first inner wall 424a and the inclined section on the second inner wall 424b may be oppositely arranged along the y direction.

[0179] In the embodiments of the present application, in the z direction, the inclined section may cover the entire first inner wall 424a or a part of the first inner wall 424a, and the inclined section is located at the end of the through groove structure facing the front fork leg 30. The size of the inclined section in the z direction is not further limited.

[0180] With such a setting, the opening at the end of the through groove structure facing the insertion direction can be made larger. During assembly, it is convenient for the engaging portion 342 to be connected to the inserting portion 424, thereby reducing the assembly difficulty. By arranging at least a part of the first inner wall 424a to include an inclined section, that is to say, a part of the first inner wall 424a is an inclined surface 411. Since the inclined surface 411 can play a guiding role, it is easier to align and insert during the insertion fit, reducing the installation difficulty. In addition, it can also reduce the possible jamming phenomenon during the insertion process, making the installation process smoother. The inclined surface 411 can remove sharp edges and corners, reducing the risk of injury to the operator during installation and maintenance. The inclined surface 411 can reduce the wear and damage to other components during the insertion process.

[0181] Continue to refer to Figure 13 shown, one end of the cover body 41 close to the assembly port 43 is provided with an inclined surface 411. The inclined surface 411 gradually inclines towards the direction away from the front fork leg 30 in the insertion direction of the decorative cover 40.

[0182] By providing an inclined surface 411 at one end of the cover body 41 close to the assembly port 43, since the inclined surface 411 can play a guiding role, it is easier to align and insert during the plug-in fit, reducing the installation difficulty. In addition, by inclining the inclined surface 411 in the plug-in direction of the decorative cover 40 and gradually tilting it away from the front fork leg 30, the end of the cover body 41 close to the assembly port 43 can be farther away from the connecting foot 34, preventing the outer paint of the front fork leg 30 from being scratched during assembly and causing the front fork leg 30 to rust easily. The inclined surface 411 can remove sharp edges and corners, reducing the risk of injury to the operator during installation and maintenance.

[0183] As Figure 14 shown, the connecting foot 34 may include a first connecting portion 341, and the first connecting portion 341 includes a first end wall 3411 and a second end wall 3412 that are oppositely arranged along the first direction (x direction). The first end wall 3411 and the second end wall 3412 are mating portions 342. That is to say, both sides of the first connecting portion 341 are mating portions 342.

[0184] With such a setting, the structure of the connecting foot 34 and the mating portion 342 can be simplified, thereby reducing costs. In addition, since the mating portion 342 is the first end wall 3411 and the second end wall 3412 of the first connecting portion 341, the first connecting portion 341 can be an integral structure, which can simplify the structure of the first connecting portion 341 and improve the structural strength of the first connecting portion 341.

[0185] Continuing to refer to Figure 14 shown, in the axial direction of the front fork leg 30, a first retracted portion 3415 is provided at one end of the first end wall 3411 facing away from the front fork leg 30, and a second retracted portion 3416 is provided at one end of the second end wall 3412 facing away from the front fork leg 30. The first retracted portion 3415 and the second retracted portion 3416 gradually tilt towards each other in the opposite direction of the plug-in direction of the decorative cover 40.

[0186] With such a setting, the dimension of the first connecting portion 341 at the end facing away from the front fork leg 30 in the first direction (x direction) can be made smaller than the dimension of the first connecting portion 341 at the end facing away from the front fork leg 30 in the first direction (x direction). That is to say, the dimension of the first connecting portion 341 close to the ground is smaller, so that when the decorative cover 40 is in plug-in fit with the first connecting portion 341, collision can be avoided, assembly is convenient, and the assembly difficulty is reduced. In addition, the material used for the connecting foot 34 can be reduced, thereby reducing costs.

[0187] Exemplarily, a second connecting portion 343 may be provided at one end of the first connecting portion 341 facing away from the front fork leg 30, and the second connecting portion 343 is used for fixedly connecting with the third side wall 423. By inclining the first retracted portion 3415 and the second retracted portion 3416 gradually towards each other in the direction opposite to the insertion direction of the decorative cover, the size of the second connecting portion 343 in the first direction (x direction) is reduced, further reducing the material used for the connecting leg 34 and lowering the cost. Additionally, the smaller second connecting portion 343 can facilitate the miniaturization development of the bottom of the decorative cover 40.

[0188] In a possible implementation manner, chamfer 3413 structures are provided at one end of the first retracted portion 3415 close to the front fork leg 30 and at one end of the second retracted portion 3416 facing the front fork leg 30.

[0189] It should be noted that "chamfering" refers to beveling or rounding the edges or corners of a workpiece, usually cutting with a certain angle or radius.

[0190] By providing chamfer 3413 structures at one end of the first retracted portion 3415 close to the front fork leg 30 and at one end of the second retracted portion 3416 facing the front fork leg 30, it can play a guiding role in the assembly of the decorative cover 40 and the connecting leg 34, making the insertion portion 424 of the decorative cover 40 easier to align and insert, reducing the installation difficulty. The chamfer 3413 structure can reduce the possible jamming phenomenon during the insertion process, making the installation process smoother. It can also effectively disperse stress, reduce stress concentration points, thereby reducing the risk of material fatigue and fracture. By reducing stress concentration, the strength and durability of the overall structure can be improved. The chamfer 3413 structure can remove sharp edges and corners, reducing the risk of operators being injured during installation and maintenance. It can also reduce the wear and damage to other components during the insertion process.

[0191] In a possible implementation manner, the first connecting portion 341 may include a first connecting hole 3414. Among them, the first connecting hole 3414 is used for connecting with the front wheel 310. Specifically, the first connecting hole 3414 is used for the front wheel axle 50 to pass through. The front wheel axle 50 can pass through the first connecting hole 3414 and then penetrate into the hub 310a of the front wheel 310, thereby fixedly connecting the front wheel 310 and the connecting leg 34.

[0192] By providing the first connecting hole 3414, it can facilitate the connection with the front wheel 310. For example, it can be connected by fasteners, which can reduce the assembly difficulty.

[0193] Continue to refer to Figure 14As shown, the connecting leg 34 may include a second connecting portion 343. In the axial direction of the front fork leg 30, the second connecting portion 343 is connected to one end of the first connecting portion 341 away from the front fork leg 30. The second connecting portion 343 is used for fixedly connecting with the third side wall 423 of the decorative cover 40.

[0194] Exemplarily, a second connecting hole 3431 is provided on the second connecting portion 343. A third connecting hole 4231 corresponding to the second connecting hole 3431 is provided on the third side wall 423. The second connecting hole 3431 and the third connecting hole 4231 are connected by a fastener. Among them, the fastener can be a screw or a bolt, etc.

[0195] By providing the second connecting portion 343 and connecting the second connecting portion 343 with the third side wall 423, the connection stability between the decorative cover 40 and the connecting leg 34 can be increased, thereby preventing the decorative cover 40 from falling off and extending the service life of the decorative cover 40. By providing the second connecting hole 3431 on the second connecting portion 343, providing the third connecting hole 4231 on the third side wall 423, and connecting them by a fastener, the fastener can provide a firm connection, can withstand greater mechanical stress and load, can improve the anti-vibration and anti-impact capabilities of the connection, and ensure the stability and reliability of the connection.

[0196] In addition, the components can be disassembled and reassembled conveniently, which is convenient for maintenance and repair. Removing the fastener is simpler and faster than directly welding or gluing the third side wall 423 and the second connecting portion 343. The fastener connection can be applied to various materials, including metals, plastics, woods, etc., and has strong adaptability. This connection method is applicable to various structural forms and design requirements and has great flexibility. Fasteners usually have a low cost, and the installation process does not require complex equipment and processes, reducing the manufacturing cost. The installation process of the fastener connection is relatively simple and fast, which can significantly reduce the installation time and improve the production efficiency. Through the design of through holes and fasteners, high-precision positioning and connection can be achieved to ensure the relative positions and functions of the components. In addition, the fastener connection has high repeatability. After each disassembly and reassembly, the positions and performances of the components basically remain the same.

[0197] In a possible implementation manner, the orthographic projection of the second connecting hole 3431 on the third side wall 423 is located within the third connecting hole 4231.

[0198] With such a setting, the size of the third connection hole 4231 can be made larger, so that the third connection hole 4231 can provide a larger tolerance range, making it easier for the fastener to be aligned and inserted, and reducing the assembly difficulty. Since the third connection hole 4231 provides more space, the fastener can be inserted and fixed more quickly, thereby reducing the installation time and improving the production efficiency. The larger third connection hole 4231 can avoid forced fitting and reduce the stress and damage to the second connection part 343 during the assembly process. Furthermore, it reduces the deformation generated during the assembly of the decorative cover 40 and the connecting foot 34, and keeps the shape and size of the second connection hole 3431 stable. The larger third connection hole 4231 can compensate for the errors generated during the manufacturing process, and even if there are certain deviations in the position or size of the second connection hole 3431, it can ensure that the fastener can be installed smoothly. The larger third connection hole 4231 can increase the tolerance range, making the manufacturing and assembly of the connecting foot 34 more flexible and tolerant.

[0199] Exemplarily, the third connection hole 4231 can be an oval hole, a round hole or a special-shaped hole. With such a setting, the processing difficulty of the third connection hole 4231 can be reduced, and the design flexibility of the third connection hole 4231 can be improved. In the embodiments of the present application, no further description is made on the shape of the third connection hole 4231.

[0200] In a possible implementation manner, the decorative cover 40 can be a plastic cover.

[0201] By setting the decorative cover 40 as a plastic cover, compared with a metal part, the plastic cover is lighter, which helps to reduce the overall weight of the scooter 1000, improve the riding efficiency and comfort. The lighter scooter 1000 is easier to carry and transport, especially in the case of going up and down stairs or loading onto a vehicle. Plastic materials are usually cheaper than metal materials, and the processing technology is relatively simple, which can reduce the manufacturing cost. Plastic parts are not easy to rust and corrode, reducing the frequency of maintenance and replacement, thereby reducing the long-term use cost. Plastic materials have strong plasticity and can be manufactured into complex shapes and structures through processes such as injection molding and extrusion, meeting diverse design requirements. Plastic materials are usually softer, and the edges can be designed to be more rounded, reducing the risk of injury to the rider. High-quality plastic materials have good toughness and are not easy to break, reducing the danger during collisions or falls.

[0202] Of course, in other embodiments, the decorative cover 40 can also be set to other materials, for example, a metal decorative cover 40, an alloy decorative cover 40, a rubber decorative cover 40, etc. In the embodiments of the present application, no further description is made on the material of the decorative cover 40. The decorative cover 40 can be formed by injection molding. In the embodiments of the present application, no further limitation is made on the processing method of the decorative cover 40.

[0203] The scooter 1000 provided by the embodiment of the present application, by providing Figures 10 - 14 the front fork assembly 100 shown in the figure, can prevent sand, debris, etc. stirred up during the running of the scooter 1000 from hitting the connection between the front wheel 310 and the front fork, and extend the service life of the connection between the front wheel 310 and the front fork.

[0204] It should be noted that the front fork leg 30 is connected to the front wheel 310 through the front wheel axle 50. The front wheel 310 is provided with a wheel hub 310a. The front wheel axle 50 passes through the wheel hub 310a and is rotationally connected to the wheel hub 310a through a bearing. The front wheel axle 50 in the related art is usually a stepped shaft. However, the processing difficulty of the stepped shaft is relatively large, resulting in a relatively high cost of the connecting shaft.

[0205] Therefore, the embodiment of the present application also provides a front structure of the scooter 1000. The front structure includes a front wheel axle 50, and the front wheel axle 50 is a smooth shaft, which can solve the problem of relatively high cost caused by the front wheel axle 50 being a stepped shaft in the related art.

[0206] The following will describe in detail the front structure of the scooter 1000 in the embodiment of the present application with reference to the drawings.

[0207] The embodiment of the present application also provides a front structure of the scooter 1000. As Figure 15 shown in the figure, the front structure of the scooter 1000 may include a front wheel 310, a front fork leg 30, a bearing group 60, and a limiting component 70. The front wheel 310 includes a wheel hub 310a. One end of the front fork leg 30 is provided with a connecting foot 34, and the connecting foot 34 is used to connect with the wheel hub 310a. The front wheel axle 50 passes between the connecting foot 34 and the wheel hub 310a, and the front wheel axle 50 is of a smooth shaft structure. The bearing group 60 is arranged in the wheel hub 310a and sleeved outside the front wheel axle 50. The bearing group 60 is used to rotationally connect the wheel hub 310a and the front wheel axle 50. The bearing group 60 includes two bearings arranged at intervals along the axial direction (y direction) of the front wheel 310. The limiting component 70 is arranged between the two bearings and sleeved outside the front wheel axle 50. In the axial direction (y direction) of the front wheel 310, the limiting component 70 abuts against the two bearings, and in the radial direction of the front wheel 310, the surface of the limiting component 70 close to the wheel hub 310a abuts against the wheel hub 310a.

[0208] The front structure of the scooter 1000 in the embodiments of the present application has a relatively simple structure compared to the related art where the front wheel axle 50 is provided with a stepped axle. The optical axle structure of the front wheel axle 50 is usually a cylinder with a consistent diameter. Therefore, the manufacturing process is relatively simple and the cost is relatively low. The installation and disassembly of the optical axle structure are more convenient than those of the stepped axle because there is no need to consider the fitting and positioning of different diameter parts. By providing a limiting component 70 between the two bearings, a certain distance can be ensured between the two bearings to prevent the bearings from moving axially, thus ensuring the correct positioning and stable operation of the bearings. By arranging the side of the limiting component 70 close to the hub 310a to abut against the hub 310a in the radial direction of the front wheel 310, the limiting component 70 can be kept at the center in the radial direction of the hub 310a, and then the limiting component 70 can abut against the two bearings. In addition, it is also convenient for assembly and reduces the assembly difficulty.

[0209] It should be noted that in the embodiments of the present application, the number of the front fork legs 30 is two. The two front fork legs 30 are arranged oppositely along the axial direction of the front wheel 310 on both sides of the front wheel 310, and a connecting foot 34 is provided at one end of each front fork leg 30.

[0210] By arranging the two front fork legs 30 on both sides of the front wheel 310, better structural stability and supporting ability can be provided, making the front wheel 310 more stable when subjected to impact or load, and thus improving the overall safety of the scooter 1000. Especially when traveling at high speed or encountering obstacles, the stability of the front wheel 310 is crucial for the safety of the rider. The front fork legs 30 are evenly distributed on both sides of the front wheel 310, which can effectively disperse and evenly distribute the stress from the front wheel 310 and reduce the deformation and damage caused by unilateral force.

[0211] As Figure 16 shown, the limiting component 70 can include a first bushing 71 and a limiting member 72. The limiting member 72 is sleeved on the outside of the first bushing 71. In the axial direction of the front wheel 310, the first bushing 71 abuts against the inner rings of the two bearings. In the radial direction of the front wheel 310, the side of the limiting member 72 close to the hub 310a abuts against the hub 310a (see Figure 15 shown).

[0212] By arranging the limiting component 70 to include a first bushing 71 and a limiting member 72, and abutting the first bushing 71 against the inner rings of the two bearings, the axial movement of the bearings can be restricted, thus ensuring the correct positioning and stable operation of the bearings. Additionally, the bushing is usually made of wear-resistant materials, such as metal materials like bronze, brass, stainless steel, cast iron, alloy steel, etc., non-metal materials like nylon, polytetrafluoroethylene, polyurethane, ceramics, etc., and composite materials like metal-polymer composites, fiber-reinforced composites, etc., which can reduce the direct contact between the front wheel axle 50 and the hub 310a, thereby reducing friction and wear and extending the service life of the front wheel axle 50 and the hub 310a. By sleeving the limiting member 72 on the first bushing 71 and abutting the limiting member 72 against the hub 310a, the bushing can be held at the center in the radial direction of the hub 310a by the limiting member 72. Compared with setting a relatively thick bushing, this can reduce the weight of the bushing, make the scooter 1000 lighter, and also reduce costs.

[0213] In a possible implementation manner, the limiting member 72 is of an annular structure and has elasticity. For example, the limiting member 72 can be a PU ring or a sealing ring.

[0214] Exemplarily, the material of the limiting member 72 can be elastic materials such as rubber, polyurethane (PU), polytetrafluoroethylene, polyamide, polyoxymethylene, polyethylene, thermoplastic elastomer, polyester elastomer, polyurethane foam, silica gel, fluororubber, etc. In the embodiments of the present application, the material of the limiting member 72 is not further limited.

[0215] Exemplarily, the cross-section of the limiting member 72 can be circular, quadrilateral, pentagonal, hexagonal or irregular. The cross-section of the limiting member 72 is perpendicular to the axial direction (y direction) of the front wheel axle 50. In the embodiments of the present application, the cross-sectional shape of the limiting member 72 is not further limited.

[0216] By setting the limiting member 72 as an annular structure, it is convenient to assemble the limiting member 72 with the bushing and reduce the assembly difficulty. By setting the limiting member 72 to have elasticity, the weight of the limiting component 70 can be reduced, making the entire mechanical system lighter. The limiting member 72 having elasticity can reduce the friction and wear between the hub 310a and the first bushing 71, thereby extending the service life of the hub 310a and the first bushing 71. It can also better adapt to the gap between the first bushing 71 and the hub 310a, provide more effective sealing performance, and prevent lubricating oil leakage and entry of external contaminants. The annular structure is usually easy to install and replace. Setting the limiting member 72 as an annular structure can simplify the installation and maintenance processes of the first bushing 71 and the bearing group 60 and improve work efficiency.

[0217] In a possible implementation, the first bushing 71 and the limiting member 72 may be of a split structure, and the first bushing 71 is fixedly connected to the limiting member 72. By making the first bushing 71 and the limiting member 72 of a split structure and fixedly connecting the first bushing 71 and the limiting member 72, the processing cost of the limiting assembly 70 can be reduced, and the connection stability between the first bushing 71 and the limiting member 72 can also be ensured.

[0218] Of course, in other embodiments, the first bushing 71 and the limiting member 72 may be of an integral structure. By setting the first bushing 71 and the limiting member 72 as an integral structure, the limiting assembly 70 can be an integral structure, which is convenient for assembly and can increase the connection stability between the first bushing 71 and the limiting member 72. In the embodiments of the present application, the structures of the first bushing 71 and the limiting member 72 are not further limited.

[0219] In order to further fix the bearing group 60, in the embodiments of the present application, continue to refer to Figure 15 As shown, the front part structure of the scooter 1000 may further include a second bushing 82 and a third bushing 83. The two bearings of the bearing group 60 are respectively a first bearing 61 and a second bearing 62. In the axial direction (y direction) of the front wheel 310, the second bushing 82 is located at one end of the first bearing 61 away from the second bearing 62 and abuts against the inner ring of the first bearing 61, and one end of the second bushing 82 away from the first bearing 61 abuts against one of the two connecting feet 34. In the axial direction of the front wheel 310, the third bushing 83 is located at one end of the second bearing 62 away from the first bearing 61 and abuts against the inner ring of the second bearing 62, and one end of the third bushing 83 away from the second bearing 62 abuts against the other of the two connecting feet 34.

[0220] By providing the second bushing 82 and the third bushing 83, the axial movement of the first bearing 61 and the second bearing 62 along the front wheel 310 can be restricted, thereby ensuring the correct positioning and stable operation of the bearings. The second bushing 82 and the third bushing 83 can also limit the two connecting feet 34, avoiding unexpected deviations in the relative positions between the connecting feet 34 and the front wheel 310 caused by over-tightening or under-tightening during the assembly process.

[0221] In addition, the structures of the second bushing 82 and the third bushing 83 are simple, the cost is low, and the assembly is convenient, which can reduce the assembly difficulty. Compared with setting a structure for restricting the axial movement of the bearing on the connecting foot 34, the structure of the connecting foot 34 can be simplified, and the assembly difficulty and maintenance cost can be reduced.

[0222] It should be noted that the second bushing 82 and the third bushing 83 are both made of wear-resistant materials, such as metal materials like bronze, brass, stainless steel, cast iron, alloy steel, etc., non-metal materials like nylon, polytetrafluoroethylene, polyurethane, ceramics, etc., and composite materials like metal-polymer composites, fiber-reinforced composites, etc. In the embodiments of the present application, no further description is made for the materials of the first bushing 71, the second bushing 82, and the third bushing 83.

[0223] It should be noted that during assembly, the wheel hub 310a, the limiting component 70, the bearing group 60, the connecting feet 34, the second bushing 82, and the third bushing 83 are all located between the two connecting feet 34. By squeezing the inner rings of the first bearing 61 and the second bearing 62 with the two connecting feet 34, the inner rings of the first bearing 61 and the second bearing 62 are fixed.

[0224] In some embodiments, the axial dimensions of the second bushing 82 and the third bushing 83 in the front wheel can be adjusted, or the number of the second bushing 82 and the third bushing 83 can be adjusted, so that the connecting feet 34 can be fixedly connected to the inner ring of the bearing group 60, and further the inner rings of the two bearings in the bearing group 60 are fixed to prevent the bearings from moving axially in the front wheel 310.

[0225] In one possible implementation, as Figure 15 shown, an assembly protrusion 310b is provided inside the wheel hub 310a. Axially in the front wheel 310, the first bearing 61 and the second bearing 62 are respectively located on both sides of the assembly protrusion 310b. One side of the outer ring of the first bearing 61 facing the second bearing 62 abuts against the assembly protrusion 310b, and one side of the outer ring of the second bearing 62 facing the first bearing 61 abuts against the assembly protrusion 310b.

[0226] By providing the assembly protrusion 310b, the axial movement of the bearing outer ring can be effectively restricted, ensuring that the bearings maintain the correct position and stability during operation, and preventing the bearings from failing or being damaged due to axial displacement. The assembly protrusion 310b provides a clear positioning reference, making the installation of the bearings more precise, reducing the installation error, and improving the overall assembly quality. The assembly protrusion 310b can increase the structural rigidity of the wheel hub 310a, enhance its anti-deformation ability, improve the stability and durability of the entire system. The assembly protrusion 310b can make more effective use of the internal space of the wheel hub 310a, making the design more compact and adapting to different application requirements. By providing the assembly protrusion 310b on the wheel hub 310a, the design and manufacturing process of the bearing seat can be simplified, the need for other complex positioning and fixing devices is reduced, thereby reducing the manufacturing cost. The assembly protrusion 310b can evenly distribute the force on the bearing outer ring, reduce the stress concentration phenomenon, and extend the service life of the bearings and the wheel hub 310a.

[0227] Continue to refer toFigure 15 As shown, the front wheel axle 50 includes a first end 50a and a second end 50b arranged axially. Both the first end 50a and the second end 50b are provided with mounting holes 51. A fixing member 81 is installed in each mounting hole 51, and the outer surface of the fixing member 81 is in mating connection with the inner surface of the mounting hole 51. When the fixing member 81 is assembled in place with the mounting hole 51, the fixing member 81 abuts against the connecting leg 34 so that the connecting leg 34 is fixedly connected to the front wheel axle 50.

[0228] Exemplarily, the mounting hole 51 can be a threaded hole. Correspondingly, the outer surface of the fixing member 81 is provided with an external thread that mates with the threaded hole. Alternatively, the mounting hole 51 can be a spline hole. Correspondingly, the outer surface of the fixing member 81 is provided with splines that mate with the mounting hole 51. Of course, in other embodiments, the mounting hole 51 and the fixing member 81 can also be of other structures. In the embodiments of the present application, the specific structures of the mounting hole 51 and the fixing member 81 are not further limited.

[0229] By providing the mounting holes 51 at the first end 50a and the second end 50b of the front wheel axle 50, compared with the related art where an external thread is provided on the outside of the front wheel axle 50 and then fixed by a nut, the technical solution of the present application is applicable to a smaller assembly space and can reduce the assembly difficulty. By arranging the fixing member 81 at the first end 50a and the second end 50b of the front wheel axle 50 and abutting the connecting leg 34 through the fixing member 81, the connecting leg 34 is fixedly connected to the front wheel axle 50 and the front wheel 310, which can simplify the connection structure for fixing the front wheel 310 and the front fork leg 30, and thus reduce the cost.

[0230] Exemplarily, the fixing member 81 can be a fastener such as a bolt or a screw, or can also be a spline. This can simplify the structure of the fixing member 81, and bolts and screws are relatively common, which can reduce the cost of the fixing member 81.

[0231] Of course, in other embodiments, external threads can also be provided on the outside of the first end 50a and the second end 50b of the front wheel axle 50, and the fixing member 81 can be a nut. By screwing the nut onto the first end 50a and the second end 50b of the front wheel axle 50, the connecting leg 34 is fixedly connected to the front wheel axle 50. In the embodiments of the present application, the structures of the first end 50a and the second end 50b of the front wheel axle 50 and the structure of the fixing member 81 are not further limited.

[0232] In some embodiments, a first fitting 84 is provided between the fixing member 81 and the front wheel axle 50. The first fitting 84 is sleeved on the fixing member 81. The dimension of the first fitting 84 in the radial direction of the front wheel 310 is larger than the dimension of the fixing member 81 in the radial direction of the front wheel 310. The first fitting 84 is used to, when fixedly connecting the connecting foot 34 to the front wheel axle 50, abut against the fixing member 81 on one side and the connecting foot 34 on the other side, so as to fixedly connect the connecting foot 34 to the front wheel axle 50.

[0233] Exemplarily, the first fitting 84 may be a structure such as an annular metal gasket. In the embodiments of the present application, the structure and dimensions of the first fitting 84 are not further limited.

[0234] It should be noted that in the embodiments of the present application, the number of the first fittings 84 is not limited, and can be specifically set according to specific circumstances.

[0235] By providing the first fitting 84, the first fitting 84 can abut against the connecting foot 34, so that the size of the fixing member 81 can be reduced, the assembly space can be reduced, and thus the cost can be saved. The first fitting 84 can help evenly distribute the load of the fixing member 81, reduce local stress concentration, and prevent the connection parts of the fixing member 81, the connecting foot 34, and the front wheel axle 50 from being damaged due to excessive local stress. The first fitting 84 can fill the gap between the fixing member 81 and the front wheel axle 50, ensure a tight fit, and prevent loosening and displacement of the connection parts of the fixing member 81, the connecting foot 34, and the front wheel axle 50.

[0236] The embodiments of the present application further provide a scooter 1000, including the front part structure of the scooter 1000 shown above Figure 15 in the scooter 1000.

[0237] For the scooter 1000 provided by the embodiments of the present application, by providing the front part structure of the scooter 1000 above, by setting the front wheel axle 50 as a smooth shaft structure, compared with the stepped shaft of the front wheel axle 50 in the related art, the structure is relatively simple, usually a cylinder with a consistent diameter, so the manufacturing process is relatively simple and the cost is low. The installation and disassembly of the smooth shaft structure are more convenient than those of the stepped shaft, because the cooperation and positioning of different diameter parts do not need to be considered. By providing a limiting component 70 between the two bearings, it can be ensured that a certain distance is maintained between the two bearings, preventing the bearings from moving axially, so as to ensure the correct positioning and stable operation of the bearings. By arranging the side of the limiting component 70 close to the hub 310a to abut against the hub 310a in the radial direction of the front wheel 310, the limiting component 70 can be kept at the center in the radial direction of the hub 310a, and further the limiting component 70 can abut against the two bearings. In addition, it can also facilitate assembly and reduce the assembly difficulty.

[0238] It should be noted that fixing members 81 are usually required to be provided at both ends of the front wheel axle 50. However, providing fixing members 81 at both ends of the front wheel axle 50 will result in a relatively cumbersome assembly process and a low assembly efficiency when assembling the front wheel axle 50.

[0239] Therefore, the embodiment of the present application further provides a front part structure of a scooter 1000, which can solve the above technical problems.

[0240] The following will describe in detail the front part structure of the scooter 1000 provided in the embodiment of the present application with reference to the accompanying drawings.

[0241] The embodiment of the present application further provides a front part structure of a scooter 1000, as Figure 17 shown. The front part structure of the scooter 1000 may include a front wheel 310, two front fork legs 30, a front wheel axle 50, and a fixing member 81. The front wheel 310 includes a wheel hub 310a. The two front fork legs 30 are oppositely arranged on both sides of the front wheel 310 along the axial direction (y direction) of the front wheel 310. One connecting foot 34 is provided at one end of each front fork leg 30, and the connecting foot 34 is used to connect with the front wheel 310. The front wheel axle 50 includes a first end 50a and a second end 50b arranged along the axial direction. An installation hole 51 is provided at the second end 50b. The front wheel axle 50 passes through between the two connecting feet 34 and the wheel hub 310a, and the first end 50a is fixedly connected to one of the two connecting feet 34. A part of the outer surface of the fixing member 81 is matched with the inner surface of the installation hole 51 to realize the fixed connection between the fixing member 81 and the installation hole 51. The fixing member 81 is used to be connected in cooperation with the installation hole 51 and is fixedly connected to the other one of the two connecting feet 34. The front wheel axle 50 and the fixing member 81 are used to install the front wheel 310 between the two connecting feet 34.

[0242] Exemplarily, the installation hole 51 may be a threaded hole. Correspondingly, an external thread matched with the threaded hole is provided on the outer surface of the fixing member 81. Or, the installation hole 51 may be a spline hole. Correspondingly, a spline matched with the installation hole 51 is provided on the outer surface of the fixing member 81. Of course, in other embodiments, the installation hole 51 and the fixing member 81 may also be of other structures. In the embodiment of the present application, the specific structures of the installation hole 51 and the fixing member 81 are not further limited.

[0243] In the front structure of the scooter 1000 provided in the embodiment of the present application, the two front fork legs 30 and the front wheel 310 can be fixedly connected by arranging the front wheel axle 50 and the fixing member 81.

Compared with the technical solution of connecting by a screw and two nuts in the related art, the technical solution of the present application can save one component, thereby simplifying the connection structure between the front fork legs 30 and the front wheel 310, and further reducing the cost. Moreover, in the technical solution of the present application, only one assembly of the fixing member 81 and the mounting hole 51 of the front wheel axle 50 is required to complete centering and fixing. Compared with the technical solution of the screw and the nut, the assembly process can be simplified, the assembly accuracy can be improved, and the assembly difficulty can be reduced.

[0244] In a possible implementation, as Figure 18 shown, a first plugging portion 52 is provided at the first end 50a of the front wheel axle 50.

The second sealing portion 811 is used to abut against the other one of the two connecting feet 34 when the front wheel 310 is mounted between the two connecting feet 34. Thereby, the two connecting feet 34 are fixed between the first end 50a and the second end 50b of the front wheel axle 50.

[0248] Exemplarily, when the cross-section of the second sealing portion 811 is a circular structure, the diameter of the second sealing portion 811 is greater than the inner diameter of the mounting hole 51. When the cross-section of the second sealing portion 811 is a hexagon, the maximum dimension of the second sealing portion 811 in the radial direction of the front wheel 310 is greater than the inner diameter of the mounting hole 51.

[0249] Exemplarily, the second sealing portion 811 may be a hexagon nut or an internal hexagon nut structure, and is provided at one end of the fixing member 81 by welding or integral molding. In the embodiments of the present application, the shape of the second sealing portion 811 is not further limited.

[0250] By providing the second sealing portion 811 on the fixing member 81 and setting the second sealing portion 811 to protrude radially outward along the front wheel 310, when the front wheel 310 is mounted between the two connecting feet 34, a certain squeezing force can be applied to the connecting feet 34 through the second sealing portion 811, and in cooperation with the squeezing force of the first sealing portion 52, thereby fixedly connecting the front wheel axle 50 with the two connecting feet 34 on both sides of the front wheel 310, and the fixing reliability of the connecting feet 34 and the front wheel 310 can be improved. In addition, by providing the second sealing portion 811, it is convenient to connect the assembling fixing member 81 with a tool, reducing the assembling difficulty.

[0251] Exemplarily, the fixing member 81 may be a bolt or a screw structure. In the embodiments of the present application, the specific structure of the fixing member 81 is not further limited.

[0252] In a possible implementation, as Figure 19 shown, the first sealing portion 52 includes a first assembly hole 521. Among them, the first assembly hole 521 is located on the side of the first sealing portion 52 facing away from the second end 50b of the front wheel axle 50, and the first assembly hole 521 is connected to an assembling tool when the front wheel 310 is mounted between the two connecting feet 34.

[0253] The second sealing portion 811 includes a second assembly hole 8111. The second assembly hole 8111 is located on the side of the second sealing portion 811 facing away from the front wheel axle 50, and the second assembly hole 8111 is connected to an assembling tool when the front wheel 310 is mounted between the two connecting feet 34.

[0254] Exemplarily, the first assembly hole 521 and the second assembly hole 8111 can be a shape that can be matched with a hex wrench, a Phillips screwdriver or a flat-head screwdriver. Of course, it can be a specific shape that can be matched with a specific tool. In the embodiment of the present application, the shape of the first assembly hole 521 and the second assembly hole 8111 is not further limited.

[0255] By providing the first assembly hole 521 on the side of the first blocking portion 52 away from the second end 50b of the front wheel axle 50, a fulcrum can be provided for the assembly tool, or it can be said that it is convenient to cooperate with the assembly tool, so that it is convenient to disassemble and assemble the front wheel axle 50 and the fixing member 81, reduce the difficulty of assembly, and improve the assembly efficiency. In addition, the first assembly hole 521 can be connected to a screwdriver, a hexagonal wrench, etc. Compared with the use of a fixed-end wrench or a flexible-end wrench for a nut, a screwdriver and a hexagonal wrench require a smaller installation space, which can reduce the difficulty of assembly.

[0256] By providing the second assembly hole 8111 on the side of the second blocking portion 811 away from the front wheel axle 50, a fulcrum can be provided for the assembly tool, or it can be said that it is convenient to cooperate with the assembly tool, so that it is convenient to disassemble and assemble the front wheel axle 50 and the fixing member 81, reduce the difficulty of assembly, and improve the assembly efficiency.

[0257] In one possible implementation, see Figure 17 As shown, the front structure of the scooter 1000 may further include a first assembly part 84. The first assembly part 84 is sleeved on the fixing part 81, and the size of the first assembly part 84 in the radial direction of the front wheel 310 is larger than the size of the second blocking part 811 in the radial direction of the front wheel 310. The first assembly part 84 is used to abut against the second blocking part 811 on one side and against the other of the two connecting legs 34 on the other side when the front wheel 310 is installed between the two connecting legs 34.

[0258] Exemplarily, the first assembly part 84 may be a structure such as an annular metal gasket. In the embodiment of the present application, the structure and size of the first assembly part 84 are not further limited.

[0259] In some other embodiments of the present application, a first assembly part 84 may also be provided between the first blocking portion 52 and the connecting leg 34. In the embodiments of the present application, the number of the first assembly parts 84 is not limited and may be provided according to specific circumstances.

[0260] By providing the first fitting 84, the first fitting 84 can abut against the connecting pin 34, so that the size of the first sealing portion 52 can be reduced, thereby saving costs. The first fitting 84 can help evenly distribute the load of the first sealing portion 52, reduce local stress concentration, and prevent the connecting portion of the first sealing portion 52, the connecting pin 34, and the front wheel axle 50 from being damaged due to excessive local force.

[0262] By providing the bearing set 60, a rotational connection can be achieved between the front wheel axle 50 and the front wheel 310. Since the front wheel axle 50 is fixedly connected to the front fork leg 30, a rotational connection can be achieved between the front fork leg 30 and the front wheel 310, so that the front wheel 310 can rotate relative to the front fork leg 30, and thus the scooter 1000 can move forward or backward. In addition, the bearing set 60 can reduce the friction between the front wheel 310 and the front wheel axle 50, enabling the front wheel 310 to rotate smoothly. This helps improve the operating efficiency and speed of the scooter 1000. By reducing friction, the bearing set 60 can reduce energy loss, making the ride more labor-saving and efficient. The bearing set 60 can ensure that the front wheel 310 remains stable during high-speed rotation, reduce vibration and shaking, and improve the riding stability and comfort. The bearing set 60 can withstand the axial and radial loads generated during the riding of the scooter 1000, ensuring the normal operation of the front wheel 310 under various load conditions. In addition, the bearing set 60 can effectively disperse and transfer stress, reduce the direct impact on the front fork leg 30 and the frame 410, and protect other components.

[0263] It should be noted that the connecting pin 34 of the front fork leg 30 in the embodiments of the present application can be Figure 14 the same as the structure of the connecting pin 34 shown in Figure 10 In addition, a decorative cover 40 as shown in the embodiment can be provided on the outer side of the connecting pin 34.

Specifically, by setting the second end 50b of the front wheel axle 50 as the mounting hole 51 and connecting the partial outer surface of the fixing member 81 with the mounting hole 51, the fixed connection between the fixing member 81 and the mounting hole 51 can be realized. Compared with the technical solution of connecting by a screw and two nuts in the related art, the technical solution of the present application can save one component, thereby simplifying the structure of the connecting structure between the front fork legs 30 and the front wheel 310, and further reducing the cost. Moreover, for the technical solution of the present application, only one assembly of the fixing member 81 and the mounting hole 51 of the front wheel axle 50 is required to complete centering and fixing. Compared with the technical solution of the screw and the nut, the assembly process can be simplified, the assembly accuracy can be improved, and the assembly difficulty can be reduced. Figure 17
