Description

Technical Field

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

[0002] 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.

[0003] Generally, a bearing and a connecting shaft are provided inside the hub of a scooter wheel. The connecting shaft is rotatably connected to the bearing, and the connecting shaft is fixedly connected to the front fork, thereby rotatably connecting the front fork to the wheel. Usually, the connecting shaft adopts a stepped shaft, and the stepped shaft can prevent the bearing from moving axially along the connecting shaft, increasing the stability of the bearing.

[0004] However, the processing difficulty of the stepped shaft is relatively large, resulting in a relatively high cost of the connecting shaft. Summary of the Utility Model

[0005] The embodiment of the present application provides a front structure of a scooter and a scooter. By setting the front wheel shaft as a smooth shaft structure, the processing difficulty of the front wheel shaft can be reduced, and thus the cost can be reduced.

[0006] The first aspect of the embodiment of the present application provides a front structure of a scooter, including:

[0007] A front wheel, including a hub;

[0008] A front fork leg, one end of which is provided with a connecting foot for connecting with the hub;

[0009] A front wheel shaft, passing through between the connecting foot and the hub, and the front wheel shaft is a smooth shaft structure;

[0010] A bearing group, arranged inside the hub and sleeved outside the front wheel shaft, the bearing group is used to rotatably connect the hub to the front wheel shaft, and the bearing group includes two bearings arranged at intervals along the axial direction of the front wheel;

[0011] A limiting component, arranged between the two bearings and sleeved outside the front wheel shaft. In the axial direction of the front wheel, the limiting component abuts against both of the two bearings, and in the radial direction of the front wheel, the surface of the limiting component close to the hub abuts against the hub.

[0012] In the front structure of the scooter in the embodiments of the present application, by setting the front wheel axle as a smooth shaft structure, compared with the stepped shaft set for the front wheel axle 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 relatively 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 a limiting component between the two bearings, it is possible to 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 limiting component on the radial direction of the front wheel, with the side of the limiting component close to the hub abutting against the hub, the limiting component can be kept at the center in the radial direction of the hub, and then the limiting component can abut against the two bearings. Additionally, it can facilitate assembly and reduce the assembly difficulty.

[0013] In a possible implementation manner, the limiting component includes a first shaft sleeve and a limiting member; wherein,

[0014] The limiting member is sleeved on the outer side of the first shaft sleeve;

[0015] In the axial direction of the front wheel, the first shaft sleeve abuts against the inner rings of the two bearings;

[0016] In the radial direction of the front wheel, the side of the limiting member close to the hub abuts against the hub.

[0017] By setting the limiting component to include a first shaft sleeve and a limiting member, and having the first shaft sleeve abut against the inner rings of the two bearings, this can limit the axial movement of the bearings, thereby ensuring the correct positioning and stable operation of the bearings. Additionally, the shaft sleeve is usually made of wear-resistant materials, such as metal materials, etc., which can reduce the direct contact between the front wheel axle and the hub, thereby reducing friction and wear and extending the service life of the front wheel axle and the hub. By sleeving the limiting member on the first shaft sleeve and having the limiting member abut against the hub, this can keep the shaft sleeve at the center in the radial direction of the hub through the limiting member. Compared with setting a relatively thick shaft sleeve, this can reduce the weight of the shaft sleeve, make the scooter lighter, and also reduce the cost.

[0018] In a possible implementation manner, the limiting member is of an annular structure; wherein,

[0019] The limiting member has elasticity.

[0020] By setting the limiting member as an annular structure, it is convenient to assemble the limiting member with the bushing, reducing the assembly difficulty. By making the limiting member elastic, for example, the material of the limiting member can be elastic materials such as rubber, polyurethane (PU), polytetrafluoroethylene, polyamide, polyoxymethylene, polyethylene, thermoplastic elastomer, polyester elastomer, polyurethane foam, silica gel, fluororubber, etc. This can reduce the weight of the limiting component, making the entire mechanical system lighter. The elastic limiting member can reduce the friction and wear between the hub and the first bushing, thereby extending the service life of the hub and the first bushing. It can also better adapt to the gap between the first bushing and the hub, 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, which can simplify the installation and maintenance process of the first bushing and the bearing group, improving work efficiency.

[0021] In a possible implementation, the first bushing and the limiting member are of an integral structure; or,

[0022] The first bushing and the limiting member are of a split structure, and the first bushing is fixedly connected to the limiting member.

[0023] By setting the first bushing and the limiting member as an integral structure, the limiting component can be an integral structure, which is convenient for assembly and can increase the connection stability between the first bushing and the limiting member. By making the first bushing and the limiting member of a split structure and fixedly connecting the first bushing to the limiting member, the processing cost of the limiting component can be reduced, and the connection stability between the first bushing and the limiting member can also be ensured.

[0024] In a possible implementation, the number of the front fork legs is two, and the two front fork legs are arranged oppositely along the axial direction of the front wheel on both sides of the front wheel, and one connection foot is provided at one end of each front fork leg.

[0025] By arranging two front fork legs on both sides of the front wheel, better structural stability and supporting ability can be provided, making the front wheel more stable when subjected to impact or load, thereby improving the overall safety of the scooter. Especially when traveling at high speed or encountering obstacles, the stability of the front wheel is crucial for the safety of the rider. The front fork legs are evenly distributed on both sides of the front wheel, which can effectively disperse and evenly distribute the stress from the front wheel, reducing deformation and damage caused by unilateral force.

[0026] In a possible implementation, it further includes a second bushing and a third bushing; wherein,

[0027] The two bearings of the bearing group are respectively a first bearing and a second bearing;

[0028] Axially of the front wheel, the second bushing is located at one end of the first bearing away from the second bearing and abuts against the inner ring of the first bearing, and one end of the second bushing away from the first bearing abuts against one of the two connecting feet;

[0029] Axially of the front wheel, the third bushing is located at one end of the second bearing away from the first bearing and abuts against the inner ring of the second bearing, and one end of the third bushing away from the second bearing abuts against the other of the two connecting feet.

[0030] By providing the second bushing and the third bushing, the axial movement of the first bearing and the second bearing along the front wheel can be restricted, thereby ensuring the correct positioning and stable operation of the bearings. In addition, the structures of the second bushing and the third bushing are simple, the cost is low, and the assembly is convenient, which can reduce the assembly difficulty. Compared with setting a structure on the connecting feet to restrict the axial movement of the bearing, the structure of the connecting feet can be simplified, and the assembly difficulty and maintenance cost can be reduced.

[0031] In a possible implementation, an assembly protrusion is provided in the hub; wherein,

[0032] Axially of the front wheel, the first bearing and the second bearing are respectively located on both sides of the assembly protrusion;

[0033] One surface of the outer ring of the first bearing facing the second bearing abuts against the assembly protrusion, and one surface of the outer ring of the second bearing facing the first bearing abuts against the assembly protrusion.

[0034] By providing the assembly protrusion, 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 failure or damage of the bearing caused by axial displacement. The assembly protrusion 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 can increase the structural rigidity of the hub, enhance its anti-deformation ability, and improve the stability and durability of the entire system. The assembly protrusion can make more effective use of the internal space of the hub, making the design more compact and adapting to different application requirements. By providing the assembly protrusion on the hub, 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 reduced. The assembly protrusion 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.

[0035] In a possible implementation, the front wheel shaft includes a first end and a second end; wherein,

[0036] The first end and the second end are both provided with mounting holes, and a fixing member is mounted in each mounting hole. A part of the outer surface of the fixing member is fitted with the inner surface of the mounting hole so that the fixing member is fixedly connected to the mounting hole;

[0037] When the fixing member is assembled in place with the mounting hole, the fixing member abuts against the connecting leg so that the connecting leg is fixedly connected to the front wheel axle.

[0038] By providing mounting holes at the first end and the second end of the front wheel axle, compared with the prior art solution of providing external threads on the outer side of the front wheel axle 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 at the first end and the second end of the front wheel axle and abutting the connecting leg through the fixing member, the connecting leg is fixedly connected to the front wheel axle and the front wheel, so that the connection structure for fixing the front wheel and the front fork leg can be simplified, and the cost can be reduced.

[0039] In a possible implementation manner, a first fitting is provided between the fixing member and the front wheel axle; wherein,

[0040] The first fitting is sleeved on the fixing member;

[0041] The dimension of the first fitting in the radial direction of the front wheel is larger than the dimension of the fixing member in the radial direction of the front wheel;

[0042] The first fitting is used for, when fixedly connecting the connecting leg to the front wheel axle, abutting against the fixing member on one side and the connecting leg on the other side so that the connecting leg is fixedly connected to the front wheel axle.

[0043] By providing the first fitting, the first fitting can abut against the connecting leg, so that the size of the fixing member can be reduced, the assembly space can be reduced, and the cost can be saved. The first fitting can help evenly distribute the load of the fixing member, reduce local stress concentration, and prevent the connection parts of the fixing member, the connecting leg and the front wheel axle from being damaged due to excessive local force. The first fitting can fill the gap between the fixing member and the front wheel axle to ensure a tight fit and prevent loosening and displacement of the connection parts of the fixing member, the connecting leg and the front wheel axle.

[0044] In the second aspect of the embodiments of the present application, a scooter is provided, including the front part structure of the scooter according to any one of the first aspects above.

[0045] The scooter provided by the embodiment of the present application, by setting the front structure of the scooter as described above, with the front wheel axle being a smooth shaft structure, compared with the stepped shaft of the front wheel axle 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 relatively low. The installation and disassembly of the smooth shaft structure are more convenient than that of the stepped shaft because there is no need to consider the fitting and positioning of different diameter parts. By setting a limiting component between the two bearings, it can ensure a certain distance is maintained between the two bearings, preventing the bearings from moving axially, thereby ensuring the correct positioning and stable operation of the bearings. By arranging the side of the limiting component close to the hub in the radial direction of the front wheel to abut against the hub, the limiting component can be kept at the center in the radial direction of the hub, and further, the limiting component can abut against the two bearings. In addition, it can also facilitate assembly and reduce the assembly difficulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0092] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0093] Scooters are a convenient, environmentally friendly and economical means of transportation suitable for people of all ages. Both manual scooters and electric scooters have their unique advantages and application scenarios.

[0094] like Figure 1 As shown, the scooter 1000 includes a handlebar 220, a seat tube assembly 210, a front fork assembly 100, wheels 300 and a frame 410, wherein 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.

[0095] The frame 410 is connected to the front wheel 310 through the front fork assembly 100, and the frame 410 is connected to the rear wheel 320 through the swing arm 500, 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 used for the user to stand, and is usually made of a solid material (such as aluminum alloy or composite material) and has a non-slip surface. A side support can be set on one side of the frame 410 to support the scooter 1000 when not in use.

[0096] The riser assembly 210 is used to connect the handlebar 220 and the front fork assembly 100, and the height can usually be adjusted to accommodate users of different heights. The handlebar 220 is the gripping part of the scooter 1000, and is usually made of rubber or foam material to provide a comfortable grip and anti-slip effect.

[0097] The front fork assembly 100 is a part connecting the seat tube assembly 210 and the front wheel 310, and is usually made of metal (such as aluminum alloy or steel) with high strength and durability. In the embodiment of the present application, the material of the front fork assembly 100 is not further limited.

[0098] The structure of the front fork assembly 100 will be further described below with reference to the accompanying drawings.

[0099] The present application embodiment provides a front fork assembly 100, such asFigure 2 As shown, the front fork assembly 100 may include a front fork tube 10, a front fork yoke 20, and two front fork legs 30. The two front fork legs 30 are disposed oppositely 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 a part of the structure of the front fork tube 10 is disposed on a surface 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 as shown).

[0100] It should be noted that the direction in which 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.

[0101] It should be noted that in the embodiments of the present application, "facing away from" refers to a generalized facing away from, not limited to parallel facing back to back.

[0102] 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 as shown).

[0103] The front fork leg 30 includes a strut 31, a shock absorber cylinder 32, and a shock absorber 33. During the running of the vehicle, the interaction among the three can enable the front fork leg 30 to have a shock absorption function, effectively absorb the impacts and vibrations from road surface unevenness, potholes and obstacles, reduce the impact loads transmitted to the frame 410 and the rider, thereby improving the riding comfort. At the same time, it can help maintain the continuous contact between the front wheel 310 and the ground, provide 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, and damage caused by dirt, stones and other sundries can be prevented.

[0104] In a possible implementation, the support rod 31 is inserted and fitted with the shock absorber cylinder 32.

[0105] By inserting and fitting 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 the vibration and impact from the road surface, reduce the vibration transmitted to the frame 410 and the rider, improve the riding comfort, improve the riding stability, and facilitate maintenance and replacement.

[0106] It should be noted that the shock absorption stroke of the front fork assembly 100 will directly affect the shock absorption effect of the scooter 1000. In order to increase the shock absorption stroke of the front fork assembly 100 of the scooter 1000, an embodiment of the present application provides a front fork connecting plate 20. The following will describe the front fork connecting plate 20 in the embodiments of the present application in detail with reference to the accompanying drawings.

[0107] 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.

[0108] 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.

[0109] As Figure 5 shown, the first mounting portion 22 includes a first mounting hole 22b and a mounting surface 22a. The first mounting hole 22b is used for mating connection with the front fork leg 30, and the mounting surface 22a is used for abutting against the top surface of the front fork leg 30 when assembling with the front fork leg 30. The second mounting hole 23 is located between the two first mounting holes 22b, and the center of the second mounting hole 23 is located on the central axis of the connecting plate body 21. The second mounting hole 23 is used for mating connection with the front fork tube 10.

[0110] It should be noted that, as shown in FIG. 4, in the y direction, the second mounting hole 23 is located between the two first mounting holes 22b, and the central axis n of the front fork connecting plate 20 is parallel to the x direction (the first direction).

[0111] Combined with Figure 5 and Figure 6As shown in the figure, define the projection plane perpendicular to the central axis of the connecting plate body 21 as the first projection plane. The positive projection of the central axis of the second mounting hole 23 on the first projection plane is the first projection line e. The positive projection of the straight line where the top surface of the connecting plate body 21 is located on the first projection plane is the second projection line m. The intersection point of the first projection line e and the second projection line m is the first intersection point 24. The positive projection of the central axis of the first mounting hole 22b on the first projection plane is the third projection line f. The positive projection of the straight line where the mounting surface 22a is located on the first projection plane is the fourth projection line g. The intersection point of the third projection line f and the fourth projection line g is the second intersection point 25. Define the connection line between the first intersection point 24 and the second intersection point 25 as the first straight line p. The acute angle a formed between the first straight line p and the second projection line m is greater than or equal to 0° and less than or equal to 10°.

[0112] In the embodiment of the present application, the front fork connecting plate 20 provided is configured by arranging two first mounting portions 22 symmetrically along the central axis n of the connecting plate body 21, setting the second mounting hole 23 between the two first mounting holes 22b, and the center of the second mounting hole 23 is located on the central axis n of the connecting plate body 21. In this way, the structure of the front fork connecting plate 20 can be made more symmetrical, enabling the stress and load to be evenly distributed, and improving the stability and strength of the overall structure. The symmetrically designed front fork connecting plate 20 ensures that the front fork legs 30 are evenly distributed on both sides of the front wheel 310, providing better balance and stability, especially during turning and braking, and enhancing the handling performance. The symmetric design can effectively disperse and evenly distribute the stress between the front fork connecting plate 20 and the front fork legs 30, reducing the phenomenon of local stress concentration and extending the service life of the front fork assembly 100. In addition, by arranging the first mounting portion 22 to include the first mounting hole 22b and the mounting surface 22a, it is convenient to plug and cooperate with the front fork legs 30 of the front fork assembly 100 and abut against them, improving the connection stability between the front fork legs 30 and the front fork connecting plate 20. By providing the second mounting hole 23, it is convenient to connect with the front fork legs 30 and the front fork tube 10, improving the stability of the front fork assembly 100.

[0113] The acute angle a formed between the first straight line p and the second projection line m is set to be greater than or equal to 0 and less than or equal to 10°. 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 legs 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.

[0114] Compared with the related art, such as Figure 7As shown, a V-shaped structure with an opening downward is provided on the front fork connecting plate 20. 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. Moreover, 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.

[0115] 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°.

[0116] With such a setting, the distance k between the connection surface of the front fork tube 10 and the front fork connecting plate 20 and the connection surface of the front fork leg 30 and the front fork connecting plate 20 can be 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 where a "V"-shaped structure with an opening downward is provided on the front fork connecting plate 20, 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. Moreover, 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.

[0117] 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.

[0118] 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 α formed between the first straight line p and the second projection line m is 0° on the first projection plane, the second projection line m and the mounting surface 22a are in the same plane. When the acute angle α formed between the first straight line p and the second projection line m is greater than 0°, the mounting surface 22a can be above the second projection line m or below the second projection line m. In the embodiments of the present application, the positional relationship between the mounting surface 22a and the second projection line m is not further limited. In addition, in order to ensure the strength of the front fork connecting plate 20, the front fork connecting plate 20 usually requires a certain thickness. The technical solution in the embodiments of the present application can ensure the structural strength of the front fork connecting plate 20 and also provide a large space for extending the shock absorption stroke.

[0119] 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 than the center of the first mounting hole 22b.

[0120] 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 mm and less than or equal to 35 mm.

[0121] In the front fork connecting plate 20 of the embodiments of the present application, by making the center of the second mounting hole 23 closer to the rear wheel 320 than the center of the first mounting hole 22b, and setting the distance L from the central axis of the second mounting hole 23 to the plane where the central axes of the two first mounting holes 22b are located to be greater than or equal to 10 mm and less than or equal to 35 mm, the front fork leg 30 can be made 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 tipping over and improving the riding safety. In addition, it can also prevent the front wheel 310 from colliding with the frame 410 of the scooter 1000 during steering, improving the installation performance.

[0122] 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 mm and less than or equal to 20 mm.

[0123] 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.

[0124] 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.

[0125] Continue to refer to Figure 5 As shown, the connecting plate body 21 can be a housing wall structure with an internal cavity. Among them, the housing wall structure includes a top wall 26 and a bottom wall 27 that are relatively spaced apart. The first mounting hole 22b and the second mounting hole 23 both penetrate through the top wall 26 and the bottom wall 27. Among them, the position where the second mounting hole 23 is provided protrudes along the first direction (x direction), so that the central axes of the first mounting hole 22b and the second mounting hole 23 are not in the same plane.

[0126] In the front fork connecting plate 20 of the embodiments of the present application, by setting the connecting plate body 21 as a housing wall structure with an internal cavity, the weight of the connecting plate body 21 can be significantly reduced, thereby reducing the weight of the entire scooter 1000, improving the riding efficiency and convenience. The housing wall structure with an internal cavity has certain elasticity and buffering ability, can effectively absorb and disperse the vibration and impact from the road surface, reduce the impact on the vehicle frame 410 and the rider, and improve the riding comfort. The housing wall structure with an internal cavity can be formed in various ways, 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.

[0127] 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.

[0128] In the front fork connecting plate 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 bolts and other connecting parts are tightened, thereby enhancing the clamping force, ensuring the tight connection between the front fork leg 30 or the front fork tube 10 and the front fork connecting plate 20, and preventing loosening. The 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 connecting plate 20 and the front fork assembly 100 using the front fork connecting plate 20.

[0129] 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, 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 elastic buffer 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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, facilitating 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] When the scooter 1000 is provided with the front fork connecting plate 20 in the above embodiments, 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 facing 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.

[0138] It should be noted that if the position where the front fork leg 30 is connected to the front wheel 310 is exposed to the air, sand, 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.

[0139] 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 sand, 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.

[0140] The following describes the front fork assembly 100 in the embodiment of the present application with reference to the accompanying drawings.

[0141] 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.

[0142] 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 provided around the cover body 41. The cover body 41 is connected to the side of the surrounding wall 42 facing away from the front wheel 310.

[0143] 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.

[0144] It should be noted that, in the axial direction (y direction) of the front wheel, one end of the surrounding wall 42 is connected to the cover body 41, 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, which means that the orthographic projection of the surrounding wall 42 in the axial direction (y direction) of the front wheel can cover the connecting foot 34, and there is no interference between the surrounding wall 42 and the front wheel 310.

[0145] It should be noted that when the decorative cover 40 is plugged into the connecting leg 34, the decorative cover 40 can be plugged into the connecting leg 34 along the axial direction of the front fork leg 30 from bottom to top. Figure 10 In the figure, the plugging direction is the direction indicated by the dotted line with an arrow. The direction away from the plugging direction is the opposite direction of the plugging direction.

[0146] The front fork assembly 100 provided in the embodiment of the present application can be conveniently connected to the front wheel 310 by providing a connecting foot 34 at one end of the front fork leg 30, thereby reducing the difficulty of assembly. The front structure of the scooter 1000 can be improved in aesthetics by providing a decorative cover 40, and the assembly difficulty can be reduced and the assembly efficiency can be improved by plugging and matching the decorative cover 40 with the connecting foot 34. By detachably connecting the decorative cover 40 with the connecting foot 34, when the decorative cover 40 is damaged, it can be conveniently replaced with a new decorative cover 40, thereby reducing the maintenance cost.

[0147] By providing the decorative cover 40 with a surrounding wall 42 and a cover body 41, and the cover body 41 is connected to the side of the surrounding wall 42 away from the front wheel 310, and the surrounding wall 42 is provided around the cover body 41, the decorative cover 40 can fully wrap the connection between the connecting leg 34 and the front wheel 310 from the front side, the rear side, the bottom side and the outside, so as to prevent the connection between the connecting leg 34 and the front wheel 310 from being hit by sand, gravel, debris, etc. stirred up by the scooter 1000 during driving, thereby improving the service life of the connection between the connecting leg 34 and the front wheel 310. By providing the assembly port 43, the decorative cover 40 can be easily assembled, reducing the difficulty of assembly.

[0148] In one possible implementation, Figure 11 As shown, a plug-in portion 424 is provided on the inner side of the surrounding wall 42. The plug-in portion 424 is arranged along the axial direction (z direction) of the front fork leg 30, and the plug-in portion 424 is used to be plugged and matched with the connecting leg 34 when the decorative cover 40 is assembled with the front fork leg 30. Correspondingly, the connecting leg 34 includes a matching portion 342. The matching portion 342 is arranged along the axial direction of the front fork leg 30, and the matching portion 342 is used to be plugged and matched with the plug-in portion 424 when the decorative cover 40 is assembled with the front fork leg 30.

[0149] The front fork assembly 100 provided by the embodiment 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 peripheral wall 42 of the decorative cover 40. Generally, 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.

[0150] 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, preventing the decorative cover 40 from loosening and displacing unexpectedly in the axial direction of the front wheel shaft 50, and improving the reliability of the assembly.

[0151] As Figure 12 shown, the peripheral 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.

[0152] Exemplarily, the number of the insertion portions 424 may be one, and the insertion portion 424 may be provided on the first side wall 421 or the second side wall 422. Or, 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. And, the two insertion portions 424 are oppositely arranged along the first direction for insertion and connection cooperation with the connecting leg 34.

[0153] By providing the insertion portion 424 on the first side wall 421 and / or the second side wall 422, that is, inserting on both sides of the connecting leg 34, better support can be provided for the decorative cover 40, thereby improving the stability of the connection. 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 anti-torsion ability of the structure, especially better performance 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 cleaner 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.

[0154] In some embodiments, the surrounding wall 42 of the decorative cover 40 may generally be in a "U" - shaped structure. The opening of the "U" - shaped structure is the assembly opening 43, and the opening of the "U" - shaped structure faces upward. Here, upward refers to the direction away from the ground. Of course, the bottom surface of the "U" - shaped structure, that is, the third side wall 423, may 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 may also be a linear wall - like structure. In the embodiments of the present application, the shape of the third side wall 423 is not further limited.

[0155] As Figure 12 shown, the insertion part 424 may include a first baffle 4241 and a second baffle 4242 that are oppositely arranged along the front wheel axle 50 (in the y - direction). Among them, 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 it in this way, the structure of the insertion part 424 can be simplified, the processing difficulty of the decorative cover 40 can be reduced, and thus the cost can be reduced.

[0156] Exemplarily, the first baffle 4241 and the second baffle 4242 can be fixed to the first side wall 421 and the second side wall 422 by means of integral molding, welding, bonding, etc., 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.

[0157] Of course, in some other embodiments, the through - slot structure may also be a groove structure formed on the first side wall 421 and the second side wall 422. In the embodiments of the present application, the setting manner of the through - slot structure is not further limited.

[0158] In a possible implementation manner, as Figure 13 shown, the through - slot structure may include a first inner wall 424a and a second inner wall 424b. The first inner wall 424a and the second inner wall 424b are oppositely arranged along the front wheel axle 50 (in the y - direction). At least a part of the first inner wall 424a includes an inclined section (not labeled in the figure), Figure 13 in which a part of the upper structure of the first inner wall 424a is an inclined section. Among them, the inclined section gradually inclines towards the side away from the second inner wall 424b along the insertion direction of the decorative cover 40. That is to say, the opening at the end of the through - slot structure away from the ground is larger.

[0159] Of course, in other embodiments, an inclined section may also be provided on the second inner wall 424b, and the inclined section on the first inner wall 424a and the inclined section on the second inner wall 424b may be arranged oppositely along the y - direction.

[0160] In the embodiment of the present application, in the z direction, the inclined section may cover the entire first inner wall 424a or a part of the first inner wall 424a, and the inclined section is located at one end of the through groove structure facing the front fork leg 30. No further limitation is made on the size of the inclined section in the z direction.

[0161] With such a setting, the opening at one end of the through groove structure facing the insertion direction can be made larger, which is convenient for the engaging portion 342 to be connected to the insertion portion 424 during assembly, thereby reducing the assembly difficulty. By setting 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.

[0162] 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.

[0163] By providing the 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.

[0164] 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 oppositely arranged along the first direction (x direction). The first end wall 3411 and the second end wall 3412 are the engaging portions 342. That is to say, the two sides of the first connecting portion 341 are the engaging portions 342.

[0165] With such a setting, the structures of the connecting leg 34 and the mating portion 342 can be simplified, thereby reducing costs. Additionally, the mating portion 342 is the first end wall 3411 and the second end wall 3412 of the first connecting portion 341, which can make the first connecting portion 341 an integral structure. This can simplify the structure of the first connecting portion 341 and improve the structural strength of the first connecting portion 341.

[0166] Continue to refer to Figure 14 As shown, in the axial direction of the front fork leg 30, a first constriction 3415 is provided at one end of the first end wall 3411 facing away from the front fork leg 30, and a second constriction 3416 is provided at one end of the second end wall 3412 facing away from the front fork leg 30. The first constriction 3415 and the second constriction 3416 gradually incline towards each other in the direction opposite to the insertion direction of the decorative cover 40.

[0167] With such a setting, the dimension of the first connecting portion 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 portion 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 portion 341 near the ground is smaller. In this way, when the decorative cover 40 is inserted and mated with the first connecting portion 341, collision can be avoided, assembly is facilitated, and the assembly difficulty is reduced. Additionally, the material used for the connecting leg 34 can be reduced, thereby reducing costs.

[0168] Exemplarily, a second connecting portion 343 can be provided at one end of the first connecting portion 341 facing away from the front fork leg 30, and the second connecting portion 343 is used for fixedly connecting with the third side wall 423. By inclining the first constriction 3415 and the second constriction 3416 gradually towards each other in the direction opposite to the insertion direction of the decorative cover, the dimension of the second connecting portion 343 in the first direction (x-direction) is reduced, further reducing the material used for the connecting leg 34 and lowering costs. Additionally, the smaller second connecting portion 343 can facilitate the miniaturization development of the bottom of the decorative cover 40.

[0169] In a possible implementation manner, chamfer 3413 structures are provided at one end of the first constriction 3415 near the front fork leg 30 and at one end of the second constriction 3416 facing the front fork leg 30.

[0170] It should be noted that "chamfer" refers to the beveling or rounding treatment at the edge or corner of a workpiece, usually cut at a certain angle or radius.

[0171] By providing a chamfer 3413 structure at one end of the first recessed portion 3415 close to the front fork leg 30 and at one end of the second recessed portion 3416 facing the front fork leg 30, it is possible to guide the assembly of the decorative cover 40 and the connecting foot 34, making the insertion portion 424 of the decorative cover 40 easier to align and insert, and reducing the installation difficulty. The chamfer 3413 structure can reduce the jamming phenomenon that may occur during the insertion process, making the installation process smoother. It can also effectively disperse stress, reduce stress concentration points, thereby reducing the risk of material fatigue and fracture. By reducing stress concentration, the strength and durability of the overall structure can be improved. The chamfer 3413 structure can remove sharp edges and corners, reducing the risk of injury to operators during installation and maintenance. It can also reduce wear and damage to other components during the insertion process.

[0172] In a possible implementation, the first connecting portion 341 may include a first connecting hole 3414. Among them, the first connecting hole 3414 is used to connect to the front wheel 310. Specifically, the first connecting hole 3414 is for the front wheel axle 50 to pass through. The front wheel axle 50 can pass through the first connecting hole 3414 and then penetrate into the hub 310a of the front wheel 310, thereby fixedly connecting the front wheel 310 and the connecting foot 34.

[0173] By providing the first connecting hole 3414, it is convenient to connect to the front wheel 310. For example, it can be connected by fasteners, which can reduce the assembly difficulty.

[0174] Continue to refer to 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 one end of the first connecting portion 341 facing away from the front fork leg 30. The second connecting portion 343 is used to fixedly connect to the third side wall 423 of the decorative cover 40.

[0175] Exemplarily, a second connecting hole 3431 is provided on the second connecting portion 343. A third connecting hole 4231 corresponding to the second connecting hole 3431 is provided on the third side wall 423. The second connecting hole 3431 and the third connecting hole 4231 are connected by fasteners. Among them, the fasteners can be screws or bolts, etc.

[0176] By providing the second connecting portion 343 and connecting the second connecting portion 343 to the third side wall 423, the connection stability between the decorative cover 40 and the connecting 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 connecting hole 3431 on the second connecting portion 343, providing the third connecting hole 4231 on the third side wall 423, and connecting them by fasteners, the fasteners 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.

[0177] In addition, the components can be conveniently disassembled and reassembled, facilitating maintenance and repair. Removing the fasteners is simpler and faster compared to directly welding or gluing the third side wall 423 to the second connecting portion 343. Fastener connections can be applied to various materials, including metals, plastics, woods, etc., and have strong adaptability. This connection method is applicable to a variety of structural forms and design requirements and has great flexibility. Fasteners usually have a low cost, and the installation process does not require complex equipment and processes, reducing the manufacturing cost. The installation process of fastener connections is relatively simple and fast, 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, fastener connections have high repeatability. After each disassembly and reassembly, the positions and performances of the components basically remain the same.

[0178] 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.

[0179] 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 of the decorative cover 40 and the connecting leg 34 during the assembly process and maintains the shape and size stability of the second connection hole 3431. 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.

[0180] Exemplarily, the third connection hole 4231 can be an oval hole, a round hole or a special-shaped hole. With such a setting, the processing difficulty of the third connection hole 4231 can be reduced and the design flexibility of the third connection hole 4231 can be improved. In the embodiments of the present application, the shape of the third connection hole 4231 is not further described.

[0181] In a possible implementation, the decorative cover 40 can be a plastic cover.

[0182] 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 transport, especially in the case of going up and down stairs or loading onto a vehicle. Plastic materials are usually cheaper than metal materials, and the processing technology is relatively simple, which can reduce the manufacturing cost. Plastic parts are not easy to rust and corrode, reducing the frequency of maintenance and replacement, 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 riders. High-quality plastic materials have good toughness and are not easy to break, reducing the danger during collisions or falls.

[0183] 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.

[0184] 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 the 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.

[0185] 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.

[0186] Therefore, the embodiments of the present application also provide a front structure of the scooter 1000. The front structure includes a front wheel axle 50, and the front wheel axle 50 is a smooth shaft, which can solve the problem of relatively high cost caused by the front wheel axle 50 being a stepped shaft in the related art.

[0187] 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.

[0188] The embodiments of the present application also provide a front structure of the scooter 1000, as Figure 15As shown, 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, the surface of the limit assembly 70 close to the wheel hub 310a abuts against the wheel hub 310a.

[0189] 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 fitting 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 the 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.

[0190] 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 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.

[0191] By arranging the two front fork legs 30 on both sides of the front wheel 310, better structural stability and supporting ability can be provided, making the front wheel 310 more stable when subjected to impact or load, and thus improving the overall safety of the scooter 1000. Especially when traveling at high speed or encountering obstacles, the stability of the front wheel 310 is crucial for the safety of the rider. The front fork legs 30 are evenly distributed on both sides of the front wheel 310, which can effectively disperse and evenly distribute the stress from the front wheel 310 and reduce the deformation and damage caused by unilateral force.

[0192] 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, the surface of the limiting member 72 close to the hub 310a abuts against the hub 310a (see Figure 15 as shown).

[0193] 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 lighter, and also reduce costs.

[0194] In a possible implementation manner, the limiting member 72 is of an annular structure and has elasticity. For example, the limiting member 72 can be a PU ring or a sealing ring.

[0195] 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.

[0196] 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.

[0197] 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 making the limiting member 72 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. An annular structure is generally 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.

[0198] In a possible implementation, 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.

[0199] 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.

[0200] 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.

[0201] 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 side connecting feet 34, avoiding unexpected deviations in the relative position between the connecting feet 34 and the front wheel 310 caused by over-tightening or under-tightening during the assembly process.

[0202] 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 for restricting the axial movement of the bearing on the connecting foot 34, this can simplify the structure of the connecting foot 34, reducing the assembly difficulty and maintenance costs.

[0203] It should be noted that the materials of the second bushing 82 and the third bushing 83 are both made of wear-resistant materials, such as metal materials like bronze, brass, stainless steel, cast iron, alloy steel, etc., non-metal materials like nylon, polytetrafluoroethylene, polyurethane, ceramics, etc., and composite materials like metal-polymer composites, fiber-reinforced composites, etc. In the embodiments of the present application, no further description is made for the materials of the first bushing 71, the second bushing 82, and the third bushing 83.

[0204] It should be noted that during assembly, the 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.

[0205] 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.

[0206] In a possible implementation, as Figure 15 shown, an assembly protrusion 310b is provided inside the 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.

[0207] 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 failure or damage of the bearing caused by 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, reducing the need for other complex positioning and fixing devices, thereby reducing the manufacturing cost. 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.

[0208] 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, and a fixing member 81 is installed in each mounting hole 51. 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.

[0209] 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 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.

[0210] 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 an external thread on the outside of the front wheel axle 50 and then fixing it with a nut, the technical solution of the present application is applicable to a smaller assembly space and can reduce the assembly difficulty. By arranging the fixing member 81 at the first end 50a and the second end 50b of the front wheel axle 50 and abutting the connecting leg 34 through the fixing member 81, thereby fixedly connecting the connecting leg 34 to the front wheel axle 50 and the front wheel 310, 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.

[0211] 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, so that the cost of the fixing member 81 can be reduced.

[0212] 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 leg 34 is fixedly connected to the front wheel axle 50. In the embodiments of the present application, the structures of the first end 50a and the second end 50b of the front wheel axle 50 and the structure of the fixing member 81 are not further limited.

[0213] 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 size of the first fitting 84 in the radial direction of the front wheel 310 is larger than the size of the fixing member 81 in the radial direction of the front wheel 310. The first fitting 84 is used to, when fixedly connecting the connecting leg 34 to the front wheel axle 50, abut against the fixing member 81 on one side and abut against the connecting leg 34 on the other side, so as to fixedly connect the connecting leg 34 to the front wheel axle 50.

[0214] 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 size of the first fitting 84 are not further limited.

[0215] 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.

[0216] By providing the first fitting 84, the first fitting 84 can abut against the connecting leg 34, so that the size of the fixing member 81 can be reduced, the assembly space can be reduced, and the cost can be saved. The first fitting 84 can help evenly distribute the load of the fixing member 81, reduce local stress concentration, and prevent the connecting parts of the fixing member 81, 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, ensure tight fit, and prevent loosening and displacement of the connecting parts of the fixing member 81, the connecting leg 34 and the front wheel axle 50.

[0217] 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.

[0218] The scooter 1000 provided by the embodiment of the present application, by setting the front structure of the above-mentioned scooter 1000, through 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 that of the stepped axle because there is no need to consider the fitting and positioning of different diameter parts. By setting the limiting component 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 arranging the surface of the limiting component 70 close to the hub 310a in the radial direction of the front wheel 310 to abut against the hub 310a, the limiting component 70 can be kept at the center in the radial direction of the hub 310a, and then the limiting component 70 can abut against the two bearings. In addition, it can also facilitate the assembly and reduce the assembly difficulty.

[0219] 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 more cumbersome procedures during the assembly of the front wheel axle 50 and lower assembly efficiency.

[0220] Therefore, the embodiment of the present application also provides a front structure of the scooter 1000, which can solve the above technical problems.

[0221] The following will make a detailed description of the front structure of the scooter 1000 provided by the embodiment of the present application with reference to the accompanying drawings.

[0222] The embodiment of the present application also provides a front structure of the scooter 1000, as Figure 17 shown, the front structure of the scooter 1000 may include a front wheel 310, two front fork legs 30, a front wheel axle 50, and a fixing part 81. The front wheel 310 includes a hub 310a. The two front fork legs 30 are oppositely arranged on both sides of the front wheel 310 along the axial direction (y direction) of the front wheel 310. One end of each front fork leg 30 is provided with a connecting foot 34, and the connecting foot 34 is used to connect with the front wheel 310. The front wheel axle 50 includes a first end 50a and a second end 50b arranged along the axial direction. The second end 50b is provided with a mounting hole 51. 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 with one of the two connecting feet 34.

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.

[0229] 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.

[0230] Exemplarily, the second blocking portion 811 may be a hexagonal nut or a hexagonal nut structure, which is provided at one end of the fixing member 81 by welding or integral molding.

[0232] 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.

[0233] 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.

[0234] 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.

[0235] 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.

[0236] 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.

[0237] 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. In addition, the second assembly hole 8111 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.

[0238] 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.

[0239] 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 size of the first fitting 84 are not further limited.

[0240] In some other embodiments of the present application, a first fitting 84 may also be provided between the first sealing 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 may be specifically set according to specific circumstances.

[0241] By providing the first fitting 84, the first fitting 84 can abut against the connecting leg 34, so that the size of the first sealing portion 52 can be reduced, thereby saving costs. The first fitting 84 can help evenly distribute the load of the first sealing portion 52, reduce local stress concentration, and prevent the connection parts of the first sealing 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 connection parts of the fixing member 81, the connecting leg 34, and the front wheel axle 50.

[0242] Continue to refer to Figure 17 As shown, the front structure of the scooter 1000 may further include a bearing set 60. Wherein, the bearing set 60 is sleeved on the front wheel axle 50, and the bearing set 60 is located between the front wheel axle 50 and the front wheel 310.

The inner ring of the bearing set 60 is fixedly connected to the front wheel axle 50, and the outer ring of the bearing set 60 is fixedly connected to the front wheel 310.

[0243] 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 the ride more labor-saving and efficient. The bearing set 60 can ensure that the front wheel 310 remains stable during high-speed rotation, reduce vibration and shaking, and improve the riding stability and comfort. The bearing set 60 can bear the axial and radial loads generated during the riding process of the scooter 1000, ensuring the normal operation of the front wheel 310 under various load conditions. In addition, the bearing set 60 can effectively disperse and transfer stress, reduce the direct impact on the front fork leg 30 and the frame 410, and protect other components.

[0244] It should be noted that the connecting leg 34 of the front fork leg 30 in the embodiments of the present application can be connected toFigure 14 The structure of the connecting leg 34 shown therein is the same. In addition, a decorative cover 40 as shown in the Figure 10 illustrated embodiment can be provided on the outer side of the connecting leg 34. The structures of the connecting leg 34 and the decorative cover 40 in the embodiments of the present application will not be described in detail herein.

Specifically, by setting the second end 50b of the front wheel axle 50 as the mounting hole 51, and fitting and connecting a part of the outer surface of the fixing member 81 with the mounting hole 51, the fixed connection between the fixing member 81 and the mounting hole 51 is realized. Compared with the technical solution of connecting by a screw and two nuts in the related art, the technical solution of the present application can save one component, thereby simplifying the structure of the connecting structure between the front fork 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.
