[0017] In a possible implementation, the first blocking portion includes a first assembly hole; wherein,

[0018] The first assembly hole is located on a side of the first blocking portion away from the second end of the front wheel axle, and the first assembly hole is connected to an assembly tool when the front wheel is installed between the two connecting legs.

[0019] By setting the first assembly hole on the side of the first blocking portion away from the second end of the front wheel axle, 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 and the fixing part, reduce the difficulty of assembly, and improve the assembly efficiency. In addition, the first assembly hole can be connected with 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.

[0020] In a possible implementation, the end of the fixing member facing away from the front wheel axle includes a second blocking portion; wherein,

[0021] The size of the second blocking portion in the radial direction of the front wheel is larger than the inner diameter of the mounting hole;

[0022] The second blocking portion is used to abut against one of the two connecting legs when the front wheel is installed between the two connecting legs.

[0023] By providing a second blocking portion on the fixing member and arranging the second blocking portion to protrude outward along the radial direction of the front wheel, when the front wheel is installed between the two connecting legs, a certain extrusion force can be applied to the connecting legs by the second blocking portion, and the extrusion force of the first blocking portion can be matched to fix the front wheel shaft to the two connecting legs on both sides of the front wheel, and the fixing reliability of the connecting legs and the front wheel can be improved. In addition, by providing the second blocking portion, it is convenient to connect the assembly fixing member with the tool, reducing the difficulty of assembly.

[0024] In a possible implementation, the second blocking portion includes a second assembly hole; wherein,

[0025] The second assembly hole is located on a side of the second blocking portion away from the front wheel axle, and the second assembly hole is connected to an assembly tool when the front wheel is installed between the two connecting legs.

[0026] By providing a second assembly hole on the side of the second blocking portion away from the front wheel axle, 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 and the fixing part, reduce the difficulty of assembly, and improve the assembly efficiency. In addition, the second assembly hole can be connected with 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.

[0027] In a possible implementation, it also includes a first assembly part; wherein,

[0028] The first assembly part is sleeved on the fixing part;

[0029] The size of the first assembly part in the radial direction of the front wheel is larger than the size of the second blocking part in the radial direction of the front wheel;

[0030] The first assembly member is used to abut against the second blocking portion on one side and against one of the two connecting legs on the other side when the front wheel is installed between the two connecting legs.

[0031] By setting the first assembly part, the first assembly part can be abutted against the connecting foot, so that the size of the first blocking part can be reduced, thereby saving costs. The first assembly part can help to evenly distribute the load of the first blocking part, reduce local stress concentration, and prevent the connection parts of the first blocking part, the connecting foot and the front wheel axle from being damaged due to excessive local force.

[0034] The bearing group includes an inner ring and an outer ring which are rotatably connected. The inner ring of the bearing group is fixedly connected to the front wheel axle, and the outer ring of the bearing group is fixedly connected to the front wheel.

[0035] By setting the bearing group, the front wheel shaft and the front wheel can be connected in rotation. Since the front wheel shaft is fixedly connected to the front fork leg, the front fork leg and the front wheel can be connected in rotation, so that the front wheel can rotate relative to the front fork leg, and the scooter can move forward or backward. In addition, the bearing group can reduce the friction between the front wheel and the front wheel shaft, so that the front wheel can rotate smoothly. This helps to improve the operating efficiency and speed of the scooter. By reducing friction, the bearing group can reduce energy loss, making riding more labor-saving and efficient. The bearing group can ensure that the front wheel remains stable when rotating at high speed, reduce vibration and shaking, and improve riding stability and comfort. The bearing group can withstand the axial and radial loads generated by the scooter during riding, ensuring that the front wheel operates normally under various load conditions. In addition, the bearing group can effectively disperse and transmit stress, reduce direct impact on the front fork leg and frame, and protect other components.

[0036] In a possible implementation, the connecting foot includes a first connecting portion, and the first connecting portion includes a first connecting hole; wherein,

[0037] The first connecting hole is used for the front wheel axle to pass through.

[0038] By providing the first connecting hole, the front wheel axle can pass through, and then the front fork leg and the front wheel are connected together through the front wheel axle, which can reduce the difficulty of assembly. By providing the first connecting hole, the processing difficulty of the connecting foot can be reduced, thereby reducing the cost.

[0039] In a possible implementation, a decorative cover is also included; wherein,

[0040] The decorative cover is arranged on a side of the connecting foot away from the front wheel;

[0041] The decorative cover is plug-fitted with the connecting pin and is detachably connected to the connecting pin.

[0042] By providing a decorative cover, the aesthetics of the front structure of the scooter can be improved, and the connecting foot, the front wheel axle and the fixing parts can be protected to prevent the sand, gravel, debris and the like stirred up by the scooter during driving from hitting the connection between the connecting foot, the front wheel axle and the fixing parts, thereby extending the service life of the connecting foot, the front wheel axle and the fixing parts. By plugging and matching the decorative cover with the connecting foot, the assembly difficulty 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, which can reduce the maintenance cost.

[0043] In a possible implementation, the decorative cover includes a cover body and a surrounding wall arranged around the cover body, and the cover body is located on a side of the decorative cover away from the front wheel; wherein,

[0044] 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 closer to the front wheel than the cover body;

[0045] 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.

[0046] By providing the decorative cover with a surrounding wall and a cover body, and the cover body is located on the side of the decorative cover away from the front wheel, and the surrounding wall is provided around the cover body, the decorative cover can fully wrap the connection between the connecting foot and the front wheel from the front side, the rear side, the bottom side and the outside, so as to prevent 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, and thus improve the service life of the connection between the connecting foot and the front wheel. By providing an assembly port, the decorative cover can be easily assembled, reducing the difficulty of assembly.

[0047] In a possible implementation, a plug-in portion is provided on the inner side of the surrounding wall, and the connecting pin includes a matching portion; wherein,

[0048] The plug-in portion and the matching portion are both arranged along the axial direction of the front fork leg, and the plug-in portion is used to be plugged and matched with the matching portion when the decorative cover is assembled with the front fork leg.

[0049] The front structure of the scooter in the embodiment of the present application can facilitate the plug-in fit of the decorative cover and the connecting foot by providing a plug-in portion on the surrounding wall of the decorative cover and a matching portion on the connecting foot, wherein the plug-in fit usually does not require complicated tools or equipment, and the installation and removal process is relatively simple and quick. The plug-in fit 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.

[0050] 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,

[0051] The first side wall and the second side wall are arranged opposite to each other along a first direction, wherein the first direction is perpendicular to the axial direction of the front wheel and perpendicular to the axial direction of the front fork leg;

[0052] In the first direction, one end of the third side wall is connected to the first side wall, and the other end is connected to the second side wall, and the third side wall and the assembly opening are arranged opposite to each other along the axial direction of the front fork leg;

[0053] The plug-in portion is located on the first side wall and / or the second side wall.

[0054] 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.

[0055] 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 away from each other along a first direction; wherein,

[0056] The first end wall and the second end wall are the matching parts.

[0057] 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.

[0058] In a possible implementation, the connecting foot includes a second connecting portion; wherein,

[0059] Axially of the front fork leg, the second connecting portion is located at one end of the first connecting portion away from the front fork leg;

[0060] The second connecting portion is used for fixedly connecting with the third side wall.

[0061] By providing the second connecting portion and connecting the second connecting portion with the third side wall, the connection stability between the decorative cover and the connecting foot can be increased, thereby preventing the decorative cover from falling off and prolonging the service life of the decorative cover.

[0062] In a possible implementation manner, a second connecting hole is provided on the second connecting portion;

[0063] A third connecting hole corresponding to the second connecting hole is provided on the third side wall;

[0064] The second connecting hole and the third connecting hole are connected by a fastener.

[0065] By providing the second connecting hole on the second connecting portion, providing the third connecting hole on the third side wall, and connecting them by a fastener, the fastener can provide a firm connection, can withstand large mechanical stresses and loads, can improve the anti-vibration and anti-impact capabilities of the connection, and ensure the stability and reliability of the connection. In addition, the components can be easily disassembled and reassembled, facilitating maintenance and repair. Removing the fastener is simpler and faster than welding or adhesive bonding. Fastener connections can be applied to various materials, including metals, plastics, woods, etc., and have strong adaptability. This connection method is suitable for various structural forms and design requirements and has great flexibility. Fasteners usually have low costs, 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, 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, ensuring the relative positions and functions of the components. In addition, fastener connections have high repeatability, and after each disassembly and reassembly, the positions and performances of the components basically remain the same.

[0066] In a possible implementation manner, the orthographic projection of the second connecting hole on the third side wall is located within the third connecting hole.

[0067] With such a setting, the size of the third connecting hole can be made larger, so that the third connecting hole 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 connecting hole 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 connecting hole can avoid forced fitting, reduce the stress and damage to the second connecting part during the assembly process. Furthermore, it reduces the deformation of the decorative cover and the connecting leg during the assembly process, and keeps the shape and size of the second connecting hole stable. The larger third connecting 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 connecting hole, it can ensure that the fastener can be installed smoothly. The larger third connecting hole can increase the tolerance range, making the manufacturing and assembly of the connecting leg more flexible and tolerant.

[0068] In the second aspect of the embodiments of the present application, a scooter is provided, including the front structure of the scooter according to any one of the first aspects described above.

[0069] For the scooter provided by the embodiments of the present application, by setting the front structure of the scooter as described above, the structure of the connecting components between the front fork legs and the front wheels can be simplified, the assembly difficulty can be reduced, and the cost can be reduced. Specifically, by setting the second end of the front wheel axle as a threaded hole and providing an external thread on the fixing member that mates with the threaded hole, 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 and the front wheels, and further reducing the cost. Moreover, for the technical solution of the present application, only one assembly of the fixing member with the threaded hole of the front wheel axle is required to complete the centering and fixing. Compared with the technical solution of the screw and nut, the assembly process can be simplified, the assembly accuracy can be improved, and the assembly difficulty can be reduced.

[0116] 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. Apparently, 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.

[0117] 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.

[0118] 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.

[0119] 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 rocker arm 500, so as to connect the various components of the scooter 1000 into an integral structure. Among them, the upper surface of the frame 410 is for users 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 support can be arranged on one side of the frame 410 for supporting the scooter 1000 when not in use.

[0120] The riser assembly 210 is used to connect the handlebar 220 and the front fork assembly 100, and its height can usually be adjusted to suit 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.

[0121] The front fork assembly 100 is the part connecting the riser assembly 210 and the front wheel 310. It is usually made of metal (such as aluminum alloy or steel) and has high strength and durability. In the embodiments of the present application, no further limitation is imposed on the material of the front fork assembly 100.

[0122] The structure of the front fork assembly 100 will be further described below with reference to the accompanying drawings.

[0123] Embodiments of the present application provide 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 oppositely arranged 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 arranged 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).

[0124] 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. The axial directions of the front fork legs 30 and the front fork tube 10 are both represented as the z direction.

[0125] It should be noted that in the embodiments of the present application, "facing away" refers to a broad sense of facing away, not limited to the parallel and opposite back-to-back.

[0126] In a possible implementation, as Figure 3 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 yoke 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 has elasticity, 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 yoke 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 shown).

[0127] The front fork leg 30 includes a strut 31, a shock absorber cylinder 32, and a shock absorber 33. During vehicle operation, the interaction among the three enables the front fork leg 30 to have a shock-absorbing function, effectively absorbing impacts and vibrations from road unevenness, potholes, and obstacles, reducing the impact loads transmitted to the frame 410 and the rider, and thus improving riding comfort. At the same time, it can help maintain continuous contact between the front wheel 310 and 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 disposing 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 debris.

[0128] In a possible implementation, the support rod 31 is inserted and cooperated with the shock absorber cylinder 32.

[0129] By inserting and cooperating the support rod 31 with 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 vibrations and impacts from the road surface, reduce the vibrations transmitted to the frame 410 and the rider, improve riding comfort, improve riding stability, and facilitate maintenance and replacement.

[0130] It should be noted that the shock-absorbing stroke of the front fork assembly 100 will directly affect the shock-absorbing effect of the scooter 1000. To increase the shock-absorbing 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 drawings.

[0131] An embodiment of the present application provides a front fork connecting plate 20, as Figure 4 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.

[0132] 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.

[0133] As Figure 5As 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 mating connection with the front fork leg 30, and the mounting surface 22a is used to abut 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 link plate body 21. The second mounting hole 23 is used for mating connection with the front fork tube 10.

[0134] 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 link plate 20 is parallel to the x direction (the first direction).

[0135] Combined with Figure 5 and Figure 6 As shown, a projection plane perpendicular to the central axis of the link plate body 21 is defined 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 link 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. The connection line between the first intersection point 24 and the second intersection point 25 is defined 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°.

[0136] In the embodiment of the present application, for the front fork link plate 20 provided, by providing two first mounting portions 22 symmetrically arranged along the central axis n of the link 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 link plate body 21. In this way, the structure of the front fork link 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 link 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, enhancing the handling performance. The symmetric design can effectively disperse and evenly distribute the stress between the front fork link 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 providing the first mounting portion 22 to include the first mounting hole 22b and the mounting surface 22a, it is convenient to plug and mate with the front fork leg 30 of the front fork assembly 100 and abut against it, improving the connection stability between the front fork leg 30 and the front fork link plate 20. By providing the second mounting hole 23, it is convenient to connect with the front fork leg 30 and the front fork tube 10, improving the stability of the front fork assembly 100.

[0137] It is set to be greater than or equal to 0 and less than or equal to 10° by the acute angle a formed between the first straight line p and the second projection line m. In this way, the distance k from the connection surface between the front fork tube 10 and the front fork connecting plate 20 to the connection surface between 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.

[0138] 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.

[0139] 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°.

[0140] With such a setting, the distance k from the connection surface between the front fork tube 10 and the front fork connecting plate 20 to the connection surface between the front fork leg 30 and the front fork connecting plate 20 can be further reduced, 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, 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 (mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20 upward, further 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.

[0141] 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.

[0142] It should be noted that when the front fork connecting 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 located 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. Additionally, to ensure the strength of the front fork connecting plate 20, the front fork connecting plate 20 generally requires a certain thickness. The technical solution in the embodiments of the present application can ensure the structural strength of the front fork connecting plate 20 and also provide a larger space for extending the shock absorption stroke.

[0143] In a possible implementation, as Figure 8 shown, when the front fork connecting plate 20 is assembled to 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.

[0144] 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.

[0145] In the front fork connecting plate 20 in the embodiments of the present application, by making the center of the second mounting hole 23 closer to the rear wheel 320 relative to 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 millimeters and less than or equal to 35 millimeters, the front fork leg 30 can be made farther away from the rear wheel 320, while the front fork tube 10 is closer to the rear wheel 320. This can shorten the axial length of the front fork tube 10, reduce the swing amplitude during steering, improve the steering accuracy and response speed, enhance the handling performance, and also lower the center of gravity of the scooter 1000, making the vehicle more stable, especially when driving at high speed and turning, reducing the risk of overturning and improving the riding safety. Additionally, it can prevent the front wheel 310 from colliding with the frame 410 of the scooter 1000 during steering and improve the installation performance.

[0146] In a possible implementation, 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 20 millimeters.

[0147] 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.

[0148] 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 embodiments 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 dimensions of the scooter 1000.

[0149] Continue to refer to Figure 5 As shown, the link 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 and 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.

[0150] In the front fork link 20 of the embodiments of the present application, by setting the link plate body 21 as a shell wall structure with an internal cavity, the weight of the link plate body 21 can be significantly reduced, thereby reducing the weight of the entire scooter 1000, and improving the riding efficiency and convenience. The shell wall structure with an internal cavity has certain elasticity and buffering capacity, and 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 shell wall structure with an internal cavity can be formed in various ways, for example, casting, stamping, 3D printing, etc., which can reduce the manufacturing difficulty and cost, and improve the production efficiency. By setting both the first mounting hole 22b and the second mounting hole 23 to penetrate through 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.

[0151] Exemplarily, the bottom wall 27 is provided with a slotted structure 271, and the slotted structure 271 extends from the first mounting hole 22b to the second mounting hole 23. Among them, there are two slotted structures 271, which are respectively arranged on both sides of the second mounting hole 23.

[0152] In the front fork link 20 of the embodiments of the present application, by providing the slotted structure 271 on the bottom wall 27, the first mounting hole 22b or the second mounting hole 23 can generate certain elastic deformation when the connecting piece such as a bolt is 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 link 20, and preventing loosening. The slotted 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 link 20 and the front fork assembly 100 using the front fork link 20.

[0153] The slotted design makes the front fork leg 30 and the front fork tube 10 more flexible during installation and adjustment, facilitating alignment and positioning, and ensuring precise fit between the front fork leg 30, the front fork tube 10 and the front fork connecting plate 20. The slotted design can provide a certain amount of elastic cushioning to absorb vibrations and impacts generated during riding, reduce damage to the front fork assembly 100, and improve riding comfort. The slotted design can accommodate manufacturing tolerances within a certain range, ensure reliable connection between the front fork leg 30, the front fork tube 10 and the front fork connecting plate 20, and reduce assembly problems caused by manufacturing errors. The slotted design can reduce the weight of the front fork connecting plate 20 without significantly affecting its strength, contribute to the lightweight design of the overall scooter 1000, and improve riding performance.

[0154] It should be noted that the shapes of the two slotted structures 271 can be the same or different. In addition, the two slotted structures 271 can be symmetrically arranged on both sides of the second mounting hole 23 or asymmetrically arranged. In the embodiments of the present application, the shape and the setting position of the slotted structure 271 are not further limited.

[0155] Continue to refer to Figure 5 As shown, the top wall 26 of the connecting plate body 21 may include a convex edge structure 261. Among them, the convex edge structure 261 is arranged around the first mounting hole 22b, and the surface of the convex edge structure 261 facing the bottom wall 27 is the mounting surface 22a.

[0156] It should be noted that in the embodiments of the present application, "facing" refers to the general sense of facing, not limited to the face-to-face orientation.

[0157] In some embodiments, the front fork leg 30 can be fixedly connected to the front fork connecting plate 20 through fasteners, such as screws, bolts, etc. Among them, the screw includes a screw head, and the bolt includes a bolt head. By providing the convex edge structure 261, the opening of the first mounting hole 22b on the top wall 26 can be made smaller, which is convenient for providing a support position for the fastener to facilitate fixed connection with the fastener. In addition, an installation surface 22a can be formed on the surface of the convex edge structure 261 facing the bottom wall 27 to form a support with the front fork leg 30, which is convenient for fixed connection with the front fork leg 30. By arranging the convex edge structure 261 on the top wall 26, the distance between the connection surface of the front fork connecting plate 20 and the front fork tube 10 and the installation surface 22a between the front fork leg 30 and the front fork connecting plate 20 can be reduced, thereby reducing the influence of the structure of the front fork connecting plate 20 itself on the shock absorption stroke. In addition, the convex edge structure 261 is convenient for processing, can reduce the processing difficulty of the front fork connecting plate 20, and thus reduce the cost.

[0158] 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.

[0159] 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.

[0160] The front fork assembly 100 provided in the embodiment of the present application can reduce the distance from the connection surface of the front fork link plate 20 and the front fork tube 10 to the connection surface (installation surface 22a) of the front fork leg 30 and the front fork link plate 20 by setting the above-mentioned front fork link plate 20, thereby reducing the influence of the structure of the front fork link plate 20 itself on the shock absorption stroke. Compared with the related art, in which the front fork link plate 20 is set with a downward opening V-shaped structure, the technical solution of the present application can translate the connection surface (installation surface 22a) between the front fork leg 30 and the front fork link plate 20 upward, release the space below the connection surface (installation surface 22a) between the front fork leg 30 and the front fork link plate 20, thereby providing a setting space for increasing the shock absorption stroke, so that the scooter 1000 used with the front fork link plate 20 can have a larger shock absorption stroke, thereby having a better shock absorption effect, and in this way, the height of the front fork tube 10 will not be increased, so that the packaging of the scooter 1000 is smaller, and the packaging cost can be reduced.

[0161] When the scooter 1000 is provided with the front fork connecting plate 20 in the above embodiment, the distance from the connecting surface between the front fork connecting plate 20 and the front fork tube 10 to the connecting surface between the front fork leg 30 and the front fork connecting plate 20 (mounting surface 22a) can also be reduced, thereby reducing the influence of the structure of the front fork connecting plate 20 itself on the shock absorption stroke. Compared with the V-shaped structure with the opening of the front fork connecting plate 20 downward in the related art, the technical solution of the present application can translate the connecting surface (mounting surface 22a) between the front fork leg 30 and the front fork connecting plate 20 upward, releasing the space below the connecting 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 will not increase the height of the front fork tube 10, making the package of the scooter 1000 smaller and reducing the packaging cost.

[0162] 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, the gravel, 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.

[0163] Therefore, the embodiment of the present application also provides a front fork assembly 100. By providing a decorative cover 40 at the connection between the front fork leg 30 and the front wheel 310, it is possible to prevent the gravel, 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.

[0164] The following will describe the front fork assembly 100 in the embodiment of the present application with reference to the accompanying drawings.

[0165] The embodiment of the present application also provides a front fork assembly 100, as Figure 10 shown. The front fork assembly 100 may include a front fork leg 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 for connecting with the front wheel 310.

[0166] In the embodiment of the present application, the decorative cover 40 is in plug-in fit 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 disposed 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.

[0167] 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 apart from the front wheel 310. The surrounding wall 42 includes an assembly port 43, and the assembly port 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.

[0168] It should be noted that, on the axial direction (y direction) of the front wheel, one end of the enclosure wall 42 is connected to the cover body 41, and the other end extends to the outside of the connecting foot 34. The enclosure wall 42 is spaced from the front wheel 310, which means that the positive projection of the enclosure wall 42 on the axial direction (y direction) of the front wheel can cover the connecting foot 34, and there is no interference problem between the enclosure wall 42 and the front wheel 310.

[0169] 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.

[0170] 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 part 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.

[0171] By providing the decorative cover 40 including the enclosure wall 42 and the cover body 41, and connecting the cover body 41 to the side of the enclosure wall 42 away from the front wheel 310, and arranging the enclosure wall 42 around the cover body 41, the decorative cover 40 can wrap the connection part between the connecting foot 34 and the front wheel 310 from the front side, rear side, bottom side and outer side, preventing the connection part between the connecting foot 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 part between the connecting foot 34 and the front wheel 310. By providing the assembly port 43, it is convenient to assemble the decorative cover 40 and reduce the assembly difficulty.

[0172] In a possible implementation manner, as Figure 11 shown, a plug-in portion 424 is provided on the inner side of the enclosure wall 42. The plug-in portion 424 is arranged along the axial direction (z direction) of the front fork leg 30. The plug-in portion 424 is used for plugging and matching with the connecting foot 34 when the decorative cover 40 is assembled with the front fork leg 30. Correspondingly, the connecting foot 34 includes a matching portion 342. The matching portion 342 is arranged along the axial direction of the front fork leg 30. The matching portion 342 is used for plugging and matching with the plug-in portion 424 when the decorative cover 40 is assembled with the front fork leg 30.

[0173] The front fork assembly 100 provided by the embodiments of the present application can facilitate the insertion and connection cooperation between the decorative cover 40 and the connecting leg 34 by providing an insertion portion 424 on the surrounding wall 42 of the decorative cover 40. Usually, the insertion and connection cooperation does not require complex tools or equipment, and the installation and disassembly processes are relatively simple and fast. The design of the insertion and connection 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.

[0174] In some embodiments, the insertion 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 mating portion 342 is inserted into the through groove structure to limit the decorative cover 40 and prevent the decorative cover 40 from loosening and displacing unexpectedly in the axial direction of the front wheel shaft 50, improving the reliability of the assembly.

[0175] 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. 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 is oppositely arranged along the axial direction of the front fork leg 30 with the assembly port 43. The insertion portion 424 is located on the first side wall 421 and / or the second side wall 422.

[0176] Exemplarily, the number of the insertion portions 424 may be one, and this insertion portion 424 may be provided on the first side wall 421 or the second side wall 422. Alternatively, the number of the insertion portions 424 is two, and the two insertion portions 424 are respectively provided on the first side wall 421 and the second side wall 422. Moreover, the two insertion portions 424 are oppositely arranged along the first direction for insertion and connection cooperation with the connecting leg 34.

[0177] By providing the insertion portion 424 on the first side wall 421 and / or the second side wall 422, that is, performing insertion on both sides of the connecting leg 34, better support can be provided for the decorative cover 40, 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. Insertion on both sides can effectively improve the torsional resistance of the structure, especially performing better when bearing lateral forces. In addition, insertion on both sides can hide the insertion portion 424 inside the structure or on the side, making the appearance neater and more beautiful. Insertion on both sides can distribute the stress more evenly, reducing the stress concentration points, thereby reducing the risk of material fatigue and damage.

[0178] 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 means 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 improve the aesthetic appearance. 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.

[0179] As Figure 12 shown, the insertion part 424 can include a first baffle 4241 and a second baffle 4242 which are oppositely arranged along the front wheel axle 50 (y - direction). Wherein, the first baffle 4241 and the second baffle 4242 are spaced apart to form a through - slot structure between the first baffle 4241 and the second baffle 4242. By setting like this, 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.

[0180] 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 means, 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.

[0181] Of course, in some other embodiments, the through - slot structure can 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 - slot structure is not further limited.

[0182] In a possible implementation manner, as Figure 13 shown, the through - slot structure can 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 (y - direction). At least part of the first inner wall 424a includes an inclined section (not labeled in the figure), Figure 13 wherein a part of the upper structure of the first inner wall 424a in the figure is an inclined section. Wherein, 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 - slot structure away from the ground is larger.

[0183] Of course, in other embodiments, an inclined section can also be provided on the second inner wall 424b, and the inclined sections on the first inner wall 424a and the second inner wall 424b can be arranged oppositely along the y - direction.

[0184] In an embodiment of the present application, in the z direction, the inclined section may cover the entire first inner wall 424a or may cover a part of the first inner wall 424a, and the inclined section is located at one end of the through groove structure facing the front fork leg 30. No further limitation is imposed on the size of the inclined section in the z direction.

[0185] With such a setting, the opening at one end of the through groove structure facing the insertion direction can be made larger, which facilitates the connection between the mating portion 342 and the insertion portion 424 during assembly, 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 a slope 411. Since the slope 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 slope 411 can remove sharp edges and corners, reducing the risk of injury to the operator during installation and maintenance. The slope 411 can reduce the wear and damage to other components during the insertion process.

[0186] Continue to refer to Figure 13 As shown, one end of the cover body 41 close to the assembly port 43 is provided with a slope 411. The slope 411 inclines gradually in the insertion direction of the decorative cover 40 away from the front fork leg 30.

[0187] By providing a slope 411 at one end of the cover body 41 close to the assembly port 43, since the slope 411 can play a guiding role, it is easier to align and insert during the insertion fit, reducing the installation difficulty. In addition, by inclining the slope 411 gradually in the insertion direction of the decorative cover 40 away from the front fork leg 30, the distance between one end of the cover body 41 close to the assembly port 43 and the connecting leg 34 can be made farther, preventing the outer paint of the front fork leg 30 from being scratched during assembly and causing the front fork leg 30 to be prone to rust. The slope 411 can remove sharp edges and corners, reducing the risk of injury to the operator during installation and maintenance.

[0188] As Figure 14 shown, the connecting leg 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 arranged opposite to each other along the first direction (x direction). The first end wall 3411 and the second end wall 3412 are the mating portions 342. That is to say, both sides of the first connecting portion 341 are the mating portions 342.

[0189] With such a setting, the structures of the connecting leg 34 and the mating part 342 can be simplified, thereby reducing costs. In addition, the mating part 342 is the first end wall 3411 and the second end wall 3412 of the first connecting part 341, which can make the first connecting part 341 an integral structure, thus simplifying the structure of the first connecting part 341 and improving the structural strength of the first connecting part 341.

[0190] Continue to refer to Figure 14 As 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 incline towards each other in the direction opposite to the insertion direction of the decorative cover 40.

[0191] With such a setting, the dimension of the first connecting part 341 at one 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 part 341 at one 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 part 341 near the ground is smaller, so that when the decorative cover 40 is inserted and mated with the first connecting part 341, collision can be avoided, assembly is convenient, and the assembly difficulty is reduced. In addition, the material used for the connecting leg 34 can be reduced, thereby reducing costs.

[0192] Exemplarily, a second connecting part 343 can be provided at one end of the first connecting part 341 facing away from the front fork leg 30, and the second connecting part 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 dimension of the second connecting part 343 in the first direction (x direction) is reduced, further reducing the material used for the connecting leg 34 and reducing costs. In addition, the smaller second connecting part 343 can facilitate the miniaturization development of the bottom of the decorative cover 40.

[0193] 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.

[0194] It should be noted that "chamfer" refers to chamfering or rounding the edge or corner of a workpiece, usually by cutting at a certain angle or radius.

[0195] By providing a chamfer 3413 structure 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 toward the front fork leg 30, it can guide the assembly of the decorative cover 40 and the connecting foot 34, making it easier to align and insert the plug-in portion 424 of the decorative cover 40, thereby reducing the difficulty of installation. The chamfer 3413 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 chamfer 3413 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.

[0196] In a possible implementation, the first connection portion 341 may include a first connection hole 3414. The first connection hole 3414 is used to connect with the front wheel 310. Specifically, the first connection hole 3414 is used for the front wheel axle 50 to pass through. The front wheel axle 50 can pass through the first connection hole 3414 and then penetrate into the wheel hub 310a of the front wheel 310, thereby fixing the front wheel 310 and the connection foot 34.

[0197] By providing the first connection hole 3414, it is possible to facilitate connection with the front wheel 310, for example, by fasteners, which can reduce the difficulty of assembly.

[0198] Continue to see Figure 14 As shown, the connecting foot 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 an end of the first connecting portion 341 away from the front fork leg 30. The second connecting portion 343 is used to be fixedly connected to the third side wall 423 of the decorative cover 40.

[0199] Exemplarily, the second connection portion 343 is provided with a second connection hole 3431. The third side wall 423 is provided with a third connection hole 4231 corresponding to the second connection hole 3431. The second connection hole 3431 and the third connection hole 4231 are connected by a fastener, wherein the fastener may be a screw or a bolt.

[0200] By providing the second connection part 343 and connecting the second connection part 343 to the third side wall 423, the connection stability between the decorative cover 40 and the connection foot 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 connection hole 3431 on the second connection part 343 and the third connection hole 4231 on the third side wall 423, and connecting them through fasteners, the fasteners can provide a firm connection, can withstand greater mechanical stress and load, can improve the vibration and impact resistance of the connection, and ensure the stability and reliability of the connection.

[0201] In addition, the components can be conveniently disassembled and reassembled, facilitating maintenance and repair. Removing the fasteners is simpler and quicker compared to directly welding or gluing the third side wall 423 to 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 suitable for various structural forms and design requirements and has great flexibility. Fasteners generally 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 quick, which can significantly reduce the installation time and improve 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.

[0202] In a possible implementation, the orthographic projection of the second connection hole 3431 on the third side wall 423 is located within the third connection hole 4231.

[0203] 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 fasteners to be aligned and inserted, and reducing the assembly difficulty. Since the third connection hole 4231 provides more space, the fasteners can be inserted and fixed more quickly, thus reducing the installation time and improving production efficiency. The larger third connection hole 4231 can avoid forced fitting and reduce the stress and damage to the second connecting portion 343 during the assembly process. Furthermore, it reduces the deformation generated by the decorative cover 40 and the connecting leg 34 during the assembly process 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. Even if there are certain deviations in the position or size of the second connection hole 3431, it can ensure that the fasteners can be installed smoothly. The larger third connection hole 4231 can increase the tolerance range, making the manufacturing and assembly of the connecting leg 34 more flexible and forgiving.

[0204] Exemplarily, the third connection hole 4231 can be an oblong 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, the shape of the third connection hole 4231 is not further described.

[0205] In a possible implementation, the decorative cover 40 can be a plastic cover.

[0206] By setting the decorative cover 40 as a plastic cover, compared with metal parts, 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 handle, especially in cases where it is necessary to go up and down stairs or load it onto a vehicle. Plastic materials are generally 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.

[0207] 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 for 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 for the processing method of the decorative cover 40.

[0208] The scooter 1000 provided by the embodiments of the present application, by setting Figures 10 - 14 the front fork assembly 100 as shown, can prevent sand, gravel, debris, etc. stirred up during the driving 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.

[0209] 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 hub 310a, and the front wheel axle 50 passes through the hub 310a and is rotatably connected to the 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.

[0210] Therefore, the embodiments of the present application also provide a front structure of the scooter 1000, and this front structure includes a front wheel axle 50, and this 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.

[0211] The following will describe in detail the front structure of the scooter 1000 in the embodiments of the present application with reference to the accompanying drawings.

[0212] The embodiments of the present application also provide a front structure of the scooter 1000, as Figure 15As shown in the figure, the front structure of the scooter 1000 may include a front wheel 310, front fork legs 30, a bearing set 60, and a limit assembly 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. A front wheel axle 50 is disposed between the connecting foot 34 and the wheel hub 310a, and the front wheel axle 50 has a smooth shaft structure. The bearing set 60 is disposed within the wheel hub 310a and sleeved outside the front wheel axle 50. The bearing set 60 is used to rotatably connect the wheel hub 310a with the front wheel axle 50. The bearing set 60 includes two bearings spaced apart along the axial direction (y direction) of the front wheel 310. The limit assembly 70 is disposed between the two bearings and sleeved outside the front wheel axle 50. In the axial direction (y direction) of the front wheel 310, the limit assembly 70 abuts against the two bearings. In the radial direction of the front wheel 310, one surface of the limit assembly 70 close to the wheel hub 310a abuts against the wheel hub 310a.

[0213] In the front structure of the scooter 1000 in the embodiment of the present application, by setting the front wheel axle 50 with 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. Therefore, 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 there is no need to consider the fit and positioning of different diameter parts. By setting the limit assembly 70 between the two bearings, it can ensure that a certain distance is maintained between the two bearings, prevent the bearings from moving axially, and thus ensure the correct positioning and stable operation of the bearings. By setting one surface of the limit assembly 70 close to the wheel hub 310a to abut against the wheel hub 310a in the radial direction of the front wheel 310, the limit assembly 70 can be kept at the center in the radial direction of the wheel hub 310a, and then the limit assembly 70 can abut against the two bearings. In addition, it can also facilitate assembly and reduce the assembly difficulty.

[0214] It should be noted that in the embodiment of the present application, the number of the front fork legs 30 is two. The two front fork legs 30 are oppositely disposed on both sides of the front wheel 310 along the axial direction of the front wheel 310, and one connecting foot 34 is provided at one end of each front fork leg 30.

[0215] 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 being impacted or loaded, 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 to 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.

[0216] Such as Figure 16As shown, the limiting component 70 may include a first bushing 71 and a limiting member 72. The limiting member 72 is sleeved on the outer side 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, one side of the limiting member 72 close to the hub 310a abuts against the hub 310a (see Figure 15 as shown).

[0217] By arranging the limiting component 70 to include the first bushing 71 and the limiting member 72, and making the first bushing 71 abut 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. In addition, 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 making the limiting member 72 abut 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 more lightweight, and also reduce costs.

[0218] In a possible implementation, the limiting member 72 is an annular structure and the limiting member 72 has elasticity. For example, the limiting member 72 can be a PU ring or a sealing ring.

[0219] 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.

[0220] 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.

[0221] By setting the limiting member 72 as an annular structure, it is convenient to assemble the limiting member 72 with the bushing, reducing the assembly difficulty. By setting the limiting member 72 to be elastic, the weight of the limiting component 70 can be reduced, making the entire mechanical system lighter. The elastic limiting member 72 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, providing more effective sealing performance to 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 process of the first bushing 71 and the bearing group 60, improving work efficiency.

[0222] In a possible implementation manner, the first bushing 71 and the limiting member 72 can 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 to the limiting member 72, the processing cost of the limiting component 70 can be reduced, and the connection stability between the first bushing 71 and the limiting member 72 can also be ensured.

[0223] Of course, in other embodiments, the first bushing 71 and the limiting member 72 can be of an integral structure. By setting the first bushing 71 and the limiting member 72 as an integral structure, the limiting component 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.

[0224] To further fix the bearing group 60, in the embodiments of the present application, continue to refer to Figure 15 As shown, the front 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. 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. One end of the third bushing 83 away from the second bearing 62 abuts against the other of the two connecting feet 34.

[0225] By setting 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-sided 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.

[0226] In addition, the structures of the second bushing 82 and the third bushing 83 are simple, with low costs, and are convenient for assembly, which can reduce the assembly difficulty. Compared with setting a structure on the connecting feet 34 to restrict the axial movement of the bearings, this can simplify the structure of the connecting feet 34, reducing the assembly difficulty and maintenance costs.

[0227] It should be noted that the materials of the second bushing 82 and the third bushing 83 are 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.

[0228] It should be noted that during assembly, the wheel hub 310a, the limiting assembly 70, the bearing set 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.

[0229] In some embodiments, the axial dimensions of the second bushing 82 and the third bushing 83 on 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 set 60, thereby fixing the inner rings of the two bearings in the bearing set 60 and preventing the bearings from moving axially on the front wheel 310.

[0230] In a possible implementation, as Figure 15 shown, an assembly protrusion 310b is provided inside the wheel hub 310a. Axially on the front wheel 310, the first bearing 61 and the second bearing 62 are respectively located on both sides of the assembly protrusion 310b. The side of the outer ring of the first bearing 61 facing the second bearing 62 abuts against the assembly protrusion 310b, and the side of the outer ring of the second bearing 62 facing the first bearing 61 abuts against the assembly protrusion 310b.

[0231] By setting the assembly protrusion 310b, the axial movement of the outer ring of the bearing can be effectively restricted, ensuring that the bearing maintains the correct position and stability during operation, and preventing the bearing from failing or being damaged due to axial displacement. The assembly protrusion 310b provides a clear positioning reference, making the installation of the bearing more precise, reducing the installation error, and improving the overall assembly quality. The assembly protrusion 310b can increase the structural rigidity of the hub 310a, enhance its anti-deformation ability, and improve the stability and durability of the entire system. The assembly protrusion 310b can make more effective use of the internal space of the hub 310a, making the design more compact and adapting to different application requirements. By setting the assembly protrusion 310b on the hub 310a, the design and manufacturing process of the bearing seat can be simplified, the need for other complex positioning and fixing devices can be reduced, and thus the manufacturing cost can be lowered. The assembly protrusion 310b can evenly distribute the force on the outer ring of the bearing, reduce the stress concentration phenomenon, and extend the service life of the bearing and the hub 310a.

[0232] Continue to refer to Figure 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 to fixedly connect the connecting leg 34 to the front wheel axle 50.

[0233] 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.

[0234] 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 prior art solution of providing external threads on the outer side of the front wheel axle 50 and then fixing with nuts, 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. In this way, the connection structure for fixing the front wheel 310 and the front fork leg 30 can be simplified, and thus the cost can be reduced.

[0235] Exemplarily, the fixing member 81 can be a fastener such as a bolt or a screw, or can also be a spline, which 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.

[0236] Of course, in other embodiments, external threads can also be provided on the outer sides 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 foot 34 can be 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.

[0237] In some embodiments, a first fitting 84 is provided between the fixing member 81 and the front wheel axle 50, and 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 for, when fixedly connecting the connecting foot 34 to the front wheel axle 50, abutting against the fixing member 81 on one side and abutting against the connecting foot 34 on the other side, so as to fixedly connect the connecting foot 34 to the front wheel axle 50.

[0238] Exemplarily, the first fitting 84 can 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.

[0239] 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.

[0240] By providing the first fitting 84, it can abut against the connecting foot 34 through the first fitting 84, which can reduce the size of the fixing member 81, reduce the assembly space, and thus save costs. The first fitting 84 can help evenly distribute the load of the fixing member 81, reduce local stress concentration, and prevent the connecting parts of the fixing member 81, the connecting foot 34, and the front wheel axle 50 from being damaged due to excessive local force. 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 connecting parts of the fixing member 81, the connecting foot 34, and the front wheel axle 50.

[0241] 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.

[0242] The scooter 1000 provided by the embodiment of the present application, by setting the front structure of the scooter 1000 as described above, with the optical axis structure of the front wheel axle 50, compared with the stepped axle of the front wheel axle 50 in the related art, the structure is relatively simple, usually a cylinder with a consistent diameter. Therefore, the manufacturing process is relatively simple and the cost is low. The installation and disassembly of the optical axis structure are more convenient than those of the stepped axle because there is no need to consider the fit and positioning of different diameter parts. By setting a limit component 70 between the two bearings, it can ensure a certain distance is maintained between the two bearings, prevent the bearings from moving axially, and thus ensure the correct positioning and stable operation of the bearings. By arranging the side of the limit component 70 close to the hub 310a in the radial direction of the front wheel 310 to abut against the hub 310a, the limit component 70 can be kept at the center in the radial direction of the hub 310a, and then the limit component 70 can abut against the two bearings. In addition, it can also facilitate assembly and reduce the assembly difficulty.

[0243] It should be noted that fixing parts 81 are usually required to be arranged at both ends of the front wheel axle 50. However, arranging fixing parts 81 at both ends of the front wheel axle 50 will result in a more cumbersome process during assembly of the front wheel axle 50 and a lower assembly efficiency.

[0244] Therefore, the embodiment of the present application also provides a front structure of the scooter 1000, which can solve the above technical problems.

[0245] The following will make a detailed description of the front structure of the scooter 1000 provided in the embodiment of the present application with reference to the drawings.

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 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 part 81 cooperates with the inner surface of the installation hole 51 to realize the fixed connection between the fixing part 81 and the installation hole 51. The fixing part 81 is used to cooperate and connect 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 part 81 are used to install the front wheel 310 between the two connecting feet 34.

[0247] Exemplarily, the mounting hole 51 can be a threaded hole. Correspondingly, an external thread that mates with the threaded hole is provided on the outer surface of the fixing member 81. Alternatively, the mounting hole 51 can be a spline hole. Correspondingly, a spline that mates with the mounting hole 51 is provided on the outer surface of the fixing member 81. Of course, in other embodiments, the mounting hole 51 and the fixing member 81 can also have 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.

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 connection structure between the front fork leg 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 with 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.

[0249] In a possible implementation manner, as Figure 18 shown, a first blocking portion 52 is provided at the first end 50a of the front wheel axle 50. Among them, the dimension of the first blocking portion 52 in the radial direction of the front wheel 310 is greater than the outer diameter of the second end of the front wheel axle 50.

In addition, during installation and disassembly, the first blocking portion 52 can be used as a part connected to a tool to facilitate assembly.

[0252] In a possible implementation, the end of the fixing member 81 away from the front wheel axle 50 includes a second blocking portion 811. The size of the second blocking portion 811 in the radial direction of the front wheel 310 is larger than the inner diameter of the mounting hole 51. Exemplarily, the fixing member 81 can be a bolt structure. The second blocking portion 811 is used to abut against the other of the two connecting legs 34 when the front wheel 310 is installed between the two connecting legs 34. Then, the two connecting legs 34 are fixed between the first end 50a and the second end 50b of the front wheel axle 50.

[0253] Exemplarily, when the cross section of the second blocking portion 811 is a circular structure, the diameter of the second blocking portion 811 is greater than the inner diameter of the mounting hole 51. When the cross section of the second blocking portion 811 is a hexagon, the maximum dimension of the second blocking portion 811 in the radial direction of the front wheel 310 is greater than the inner diameter of the mounting hole 51.

In addition, by providing the second blocking portion 811, it is convenient to connect the assembly fixing member 81 with the tool, reducing the difficulty of assembly.

[0256] Exemplarily, the fixing member 81 may be a bolt or a screw structure. In the embodiment of the present application, the specific structure of the fixing member 81 is not further limited.

[0257] In one possible implementation, Figure 19As shown, the first blocking portion 52 includes a first assembly hole 521. The first assembly hole 521 is located on a side of the first blocking portion 52 away from the second end 50b of the front wheel axle 50, and the first assembly hole 521 is connected to an assembly tool when the front wheel 310 is installed between the two connecting legs 34.

[0258] The second blocking portion 811 includes a second assembly hole 8111. The second assembly hole 8111 is located on a side of the second blocking portion 811 away from the front wheel axle 50. The second assembly hole 8111 is connected to an assembly tool when the front wheel 310 is installed between the two connecting legs 34.

[0259] 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.

[0260] 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.

[0261] 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.

[0262] 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.

[0263] 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.

[0264] In some other embodiments of the present application, a first fitting 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 fittings 84 is not limited and can be specifically set according to specific circumstances.

[0265] By providing the first fitting 84, the first fitting 84 can abut against the connecting leg 34, so that the size of the first blocking portion 52 can be reduced, thereby saving costs. The first fitting 84 can help evenly distribute the load of the first blocking portion 52, reduce local stress concentration, and prevent the connecting portions of the first blocking portion 52, the connecting leg 34, and the front wheel axle 50 from being damaged due to excessive local force. The first fitting 84 can fill the gap between the fixing member 81 and the front wheel axle 50 to ensure a tight fit and prevent loosening and displacement of the connecting portions of the fixing member 81, the connecting leg 34, and the front wheel axle 50.

[0267] 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 to improve the running efficiency and speed of the scooter 1000. By reducing friction, the bearing set 60 can reduce energy loss, making riding more labor-saving and efficient.
