TECHNICAL FIELD

The present disclosure relates to the technical field of scooters, and in particular, to a wheel and a scooter.

BACKGROUND

With the improvement of people's living standards, people's demand for beauty of products is getting increasingly higher. As scooters are used as common means of transportation and entertainment in life, many manufacturers design wheels of the scooters in such a way that the wheels can emit light. The light-emitting wheels are highly ornamental especially at night, which is deeply liked by the public. However, in rainy or other environments in which water easily enters a scooter, water easily enters a lamp cavity structure through a gap between a wheel body and an outer end cover. This may corrode a light-emitting assembly in the lamp cavity structure, or even lead to the functional failure of the light-emitting assembly.

SUMMARY

The present disclosure provides a wheel and a scooter, which can effectively improve a waterproof effect of the wheel, ensure that impurity liquid and the like outside the wheel do not penetrate into a lamp cavity structure, and prevent the failure of a light-emitting assembly inside the lamp cavity structure.

A first protrusion and a second protrusion are arranged on a hub housing at intervals, and the first protrusion and the second protrusion jointly form a groove structure. The main function of the groove structure is to provide an isolation region in the hub housing, so as to prevent solid or liquid impurities such as dust and water drops outside the hub housing from entering the hub housing, that is, the dust or water drops first stay in the groove structure rather than immediately enter the hub housing.

It should be understood that the foregoing general descriptions and the following detailed descriptions are only examples and are explanatory, and cannot limit the present disclosure.

Some implementations of the present disclosure will be described in detail below with reference to the accompanying drawings. Without conflict, the following embodiments and features in the embodiments may be combined with each other.

As shown inFIG. 1toFIG. 28, according to a first aspect of the present disclosure, a wheel100according to the present disclosure is applicable to a scooter such as a balance vehicle, a go-kart, a kick scooter, a hoverboard, or an electric vehicle. The wheel100may include a wheel body10. The wheel body10may be regarded as a main structure of the wheel100. Therefore, the wheel body10may provide a main supporting function for the wheel100. Specifically, the wheel body10may include a hub housing11and a tire19. The tire19may cover an outer side of the hub housing11, so that the hub housing11is prevented from being squeezed and deformed, and impact resistance of the hub housing11is effectively improved. The tire19is provided with tread patterns to increase a frictional force of the wheel body10, thereby improving stability of the wheel body10.

Herein, the tire19and the hub housing11may be formed integrally, or may be separately fabricated and then assembled. The tire19may be a solid tire, or may be a non-solid tire.

In addition, the hub housing11mainly provides a support function for the wheel100. More specifically, for example, the hub housing11provides a support function for another component (for example, a light-emitting assembly described below) that is installed in the hub housing11or installed in the wheel body10, so as to prevent these components from being in direct contact with the tire19and being squeezed.

In an optional implementation, referring toFIG. 2, the wheel100may further include a light-emitting assembly60, a first optical element40, a second optical element50, and an outer end cover20. The hub housing11is provided with a lamp cavity structure14facing an outer side of the wheel100, the first optical element40is installed at a bottom of the lamp cavity structure14, and the second optical element50is installed at an opening of the lamp cavity structure14.

It should be noted that the main function of the lamp cavity structure14is to provide a cavity space on the hub housing11that is enough to accommodate relevant necessary elements, and the necessary elements include, but are not limited to, the first optical element and the second optical element. The cavity space is not particularly limited in shape, for example, the cavity space may be a cylindrical cavity. In this case, as mentioned above, the lamp cavity structure14may have a bottom and an opening opposite to the bottom.

In addition, referring toFIG. 2, a direction from the first optical element40to the second optical element50may be defined as a direction in which the outer side of the wheel100or the wheel body10is located.

In this implementation, the first optical element40mainly achieves the function of optical reflection, and a type, a shape and a manufacturing material of the first optical element are not particularly limited. Therefore, the first optical element40may be broadly understood as a mirror, and mirrors may fall into three types based on shapes: plane mirrors, spherical mirrors, and aspherical mirrors. Based on a degree of reflection, mirrors may fall into total reflection mirrors and transflective mirrors (also referred to as beam splitters). Preferably, in this implementation, the first optical element40is a plane mirror.

In this implementation, a type, a shape and a manufacturing material of the second optical element50are not particularly limited. For example, the material of the second optical element50may be acrylic or glass, so that the second optical element50has appropriate transparency and reflectivity, and has a main function of implementing transmission and reflection of light at the same time. More specifically, when at least one surface of the second optical element50is irradiated by light, part of light may pass through the second optical element50while the other part of the light may be reflected back. Based on this function, the second optical element50may be referred to as a two-way mirror for short.

In this implementation, the light-emitting assembly60is arranged between the first optical element40and the second optical element50, and the outer end cover20covers an outer side of the second optical element50, and may protect the light-emitting assembly60, the first optical element40, and the second optical element50.

In addition, the light-emitting assembly60mainly provides a light source, and a type and a shape of the light-emitting assembly60are not limited, for example, the light-emitting assembly60may be an annular band-shaped LED light bar.

In addition, the outer side of the second optical element50may mean one side of the second optical element50facing the outer side of the wheel100.

After the foregoing technical solution is adopted, because the light-emitting assembly60, the first optical element40and the second optical element50are installed in the lamp cavity structure14, and the light-emitting assembly60is arranged between the first optical element40and the second optical element50, when light emitted by the light-emitting assembly60reaches the second optical element50, part of the light is reflected, and the reflected light will be reflected again when reaching the first optical element40. Therefore, the light emitted by the light-emitting assembly60can be continuously reflected between the first optical element40and the second optical element50, and then emitted from a perspective surface of the second optical element50toward the outer side of the wheel body10, so that an observer can see a cool light effect after the light emitted by the light-emitting assembly60is infinitely reflected.

Specifically, in the present disclosure, optical characteristics of the second optical element50and the first optical element40are used to enable an entity or image of the light-emitting assembly60to be reflected back and forth between the second optical element50and the first optical element40for infinite times, so that the external observer may have the illusion that light-emitting assemblies60extend into a black hole of the wheel100one by one indefinitely, thereby increasing aesthetics of the product and improving the market competitiveness.

In an optional implementation, the first optical element40may be a plane mirror and the second optical element50may be a two-way mirror, where an area of any side of the two-way mirror is greater than an area of a reflecting surface of the plane mirror. This can ensure that all the mirror images of the light-emitting assembly reflected by the plane mirror can be seen at least from a front angle after passing through the two-way mirror, so that the area of the reflecting surface of the plane mirror does not need to be greater than or equal to the area of any side of the two-way mirror, the waste of manufacturing materials can be reduced, because, in terms of a viewing effect, when the area of the reflecting surface of the plane mirror is greater than or equal to the area of any side of the two-way mirror, the visual light effect cannot be improved, but only a cost of the plane mirror is increased.

In an optional implementation, central axes of the first optical element40and the second optical element50are collinear to ensure that mirror images of the light-emitting assembly formed by multiple reflections can be arranged neatly visually.

It should be noted that the second optical element50, the first optical element40and the light-emitting assembly60are installed in the lamp cavity structure14. It may be understood that the second optical element50, the first optical element40and the light-emitting assembly60are directly fixed in the lamp cavity structure14, or the second optical element50, the first optical element40and the light-emitting assembly60are fixed to a lamp accommodating structure13, and then the lamp accommodating structure13is installed in the lamp cavity structure14. That is, whether the second optical element50, the first optical element40and the light-emitting assembly60are directly fixed in the lamp cavity structure14or indirectly fixed in the lamp cavity structure14is not limited in the present disclosure, and the main purpose is to limit the relative positions of the second optical element50, the first optical element40and the light-emitting assembly60within the lamp cavity structure14.

In an optional implementation, referring toFIG. 2,FIG. 3,FIG. 13,FIG. 29, andFIG. 30, a first protrusion111and a second protrusion112may be provided at intervals in a contact position of the hub housing11where the hub housing11can contact the outer end cover20. Herein, the contact position of the hub housing11where the hub housing11can contact the outer end cover20may be understood as a suitable local region on the hub housing11. In this local region, the hub housing11and the outer end cover20may implement various suitable connections or contacts. For example, the local region may be represented at least as a part belonging to the hub housing11in a part A ofFIG. 2. This part may be considered as an end region adjacent to the outer end cover20of the hub housing11. In this case, the outer end cover20may be in close contact with the hub housing11in this contact position. For example, when the outer end cover20is assembled on the hub housing11, the outer end cover20and the hub housing11may be in relatively close contact in the foregoing local region.

In addition, referring toFIG. 29andFIG. 30, the first protrusion111and the second protrusion112jointly form a groove structure113. The main function of the groove structure113is to provide an isolation obstacle region in the hub housing11, so that if solid or liquid impurities such as dust or water drops outside the hub housing11enter the hub housing11, the impurities will first stay in this region and will not immediately enter the hub housing11, for example, it is difficult to enter the lamp cavity structure14and then affect some devices/circuits and the like arranged in the lamp cavity structure14.

In addition, referring toFIG. 1,FIG. 29, andFIG. 30, the first protrusion111and the second protrusion112are generally two parts of the hub housing11that extend and protrude from a position of the bottom1131of the groove structure113toward the outside direction of the wheel100. Certainly, herein, the bottom1131of the groove structure113may alternatively be considered as an end of the hub housing11opposite to the outer end cover20, and shapes of the first protrusion111and the second protrusion112are not specially limited and may be roughly considered as two ridge protrusion parts that are distributed on the hub housing11in an annular shape and that abut against the outer end cover20.

In an optional implementation, the groove structure113may be filled with a flexible member30to enhance the sealing performance between the hub housing11and the outer end cover20.

In an optional implementation, a ratio of a height H2of the first protrusion111or a height H1of the second protrusion112to an average width L1of the groove structure113is greater than 1 and less than 2.5. In this way, not only the flexible member30can be better fixed in the groove structure113, but also that a liquid such as water is affected by gravity can be utilized, so that when entering the lamp cavity structure14, the liquid such as water will pass through the groove structure113and be stored in the groove structure113, that is, the groove structure113can effectively prevent the liquid such as water from entering the lamp cavity structure14.

Specifically, when the liquid such as water enters the lamp cavity structure14from a gap between the hub housing11and the outer end cover20, the liquid such as water will enter the groove structure113. This can prevent the liquid such as water from directly entering the lamp cavity structure14through the gap between the hub housing11and the outer end cover20. In addition, when the wheel100rotates, the groove structure113can throw out the liquid such as water in the groove structure113, thereby solving the problem that the liquid such as external water enters the lamp cavity structure14from the gap between the hub housing11and the outer end cover20.

Referring toFIG. 13, the ratio of the height H2of the first protrusion111or the height H1of the second protrusion112to the average width L1of the groove structure113is greater than 1.2 and less than 1.5, or the ratio of the height H2of the first protrusion111or the height H1of the second protrusion112to the average width L1of the groove structure113is greater than 1.7 and less than 1.9. To facilitate the molding of the groove structure113, the cross section of the groove structure113is usually designed to be similar to a rectangular structure, and to facilitate the installation of the outer end cover20, the height H2of the first protrusion11I is usually designed to be greater than the height H1of the second protrusion112.

Because the groove structure113may be used to place the flexible member30, the flexible member30may be a flexible filler, such as a silicone ring, EVA foam, or a sealant. This can not only meet requirements for low waterproof level by using the groove structure113, but also meet requirements for high waterproof level by using filling the groove structure113with the flexible member30. Specifically, different waterproof structures or a combination thereof may be selected according to the requirements to meet requirements for waterproof performance of the product.

When the flexible member30is placed in a deeper groove structure113, it is easy to fix the flexible member30. However, when the flexible member30is placed in a shallower groove structure113, the flexible member30is easily separated from the groove structure113with slight vibration, thereby causing difficulties to an assembler. However, when the groove structure113is further deeper, the first protrusion111and the second protrusion112on two sides of the groove structure113will become elongated, the first protrusion111and the second protrusion112need to bear a pressure of the outer end cover20, and the first protrusion111and the second protrusion112need to bear the gravity from a whole vehicle body especially when the vehicle body with the wheel100is placed sideways, or when the wheel100collides with an obstacle. Therefore, the depth of the groove structure113needs to be at a reasonable size to ensure strength and hardness of the first protrusion111or the second protrusion112. It should be noted that the deeper groove structure113means that the ratio of the height H2of the first protrusion111or the height H1of the second protrusion112to the average width L1of the groove structure113is greater than 1, while the shallower groove structure113means that the ratio of the height H2of the first protrusion111or the height H1of the second protrusion112to the average width L1of the groove structure113is less than 1. In the present disclosure, the ratio of the height H2of the first protrusion111or the height H1of the second protrusion112to the average width L1of the groove structure113is rationally designed, for example, the ratio may be greater than 1 and less than 2.5, mainly considering the foregoing problems.

In an optional implementation, as shown inFIG. 1toFIG. 21, the outer end cover20is provided with an end cover protrusion21protruding in an axial direction, and the end cover protrusion21and the groove structure113match each other to form a labyrinth connection structure to form a waterproof wall, so that when the liquid such as water enters the lamp cavity structure14, the liquid such as water can remain in the connection structure and is prevented from directly entering the lamp cavity structure14. That the end cover protrusion21protrudes in the axial direction means that an extension direction of the end cover protrusion21is the same as a central axis direction of the outer end cover20.

In an optional implementation, referring toFIG. 7, an end of the end cover protrusion21is provided with an arc-shaped structure211which retracts toward a central axis of the end of the end cover protrusion21, and the arc-shaped structure211may be positioned inside the groove structure113and abut against a flexible member30filling the groove structure113. This can not only achieve a guiding function and facilitate the installation of the outer end cover20on the hub housing11, but also prevent the end cover protrusion21from damaging the flexible member30in the groove structure113and damaging the waterproof performance of the flexible member30. That the arc-shaped structure211retracts toward the central axis of the end of the end cover protrusion21means that the arc-shaped structure211is arranged roughly symmetrically with respect to the central axis of the end cover protrusion21, and the width of the end cover protrusion21gradually decreases from one end of the outer end cover20to a free end (that is, the end at which the arc-shaped structure211is located) of the end cover protrusion21.

In an optional implementation, the first protrusion111is arranged on an outer side of the groove structure113, and the second protrusion112is arranged on an inner side of the groove structure113, where the height of the first protrusion111is greater than that of the second protrusion112, so that an unstable connection between the outer end cover20and the hub housing11caused by production errors can be prevented. For example, if the height of the first protrusion111is designed to be the same as that of the second protrusion112, two cases may easily occur in production errors. In the first case, the height of the second protrusion112is greater than that of the first protrusion111, and in the second case, the height of the second protrusion112is less than that of the first protrusion111. This may lead to the inconsistent positions of gaps between the outer end cover20and the hub housing11, or even increase the difficulty of investigating causes of water inlet accidents of the lamp cavity structure14subsequently, and does not facilitate the determining and processing of a reference end face. After the waterproof performance in the two cases is tested, test results may be obtained, and it is concluded that when the height of the second protrusion112is less than that of the first protrusion111, the waterproof performance is better, and it is convenient to accurately control tolerance of a molding part used to mold the first protrusion111, and the tolerance of the second protrusion112may be relaxed, thereby reducing a lot of manufacturing costs.

In an optional implementation, the ratio of the height H2of the first protrusion111to the height H1of the second protrusion112is greater than 1.1 and less than 1.2. This design is performed mainly considering assembly of the outer end cover20and the hub housing11. For example, referring toFIG. 3, when the outer end cover20is installed at an outlet of the lamp cavity structure14, a certain slight gap K may be provided between the second protrusion112and the outer end cover20. Such a gap may be necessary. For example, due to tolerance and other reasons, the size of the second protrusion112may not be completely suitable, for example, local protruding irregularities occur. Such a gap K may accommodate these inappropriate sizes, so as to ensure that the outer end cover20can be stably installed on the hub housing11, and also ensure waterproof performance between the outer end cover20and the hub housing11.

In an optional implementation, referring toFIG. 15, a side face of the first protrusion111and a bottom surface of the groove structure113form an included angle α not equal to 90°; and/or, a side face of the second protrusion112and the bottom surface of the groove structure113form an included angle β not equal to 90°, so that the end cover protrusion21can be quickly inserted into the groove structure113.

In an optional implementation, the included angle α is greater than 91° and less than 95°; and/or the included angle β is greater than 91° and less than 950 to ensure that the flexible member30can be stably installed in the groove structure113. A result obtained by many experiments shows that the stability of the flexible member30is the best when the groove structure113is rectangular. In the present disclosure, the guiding function of the end cover protrusion21may be considered. Therefore, the included angle α and the included angle β may be greater than 910 and less than 93°.

In an optional implementation, referring toFIG. 11, the groove structure113is filled with a flexible member30with an L-shaped structure, and the flexible member30is provided with a roughly vertical section31and a roughly horizontal section32. The term “roughly” may be understood as allowing an angle error of plus or minus 15°. A width of the horizontal section32matches the height of the groove structure113, and the vertical section31fills between two side walls of both the end cover protrusion21and the groove structure113, so that the arc-shaped structure211on the end cover protrusion21can squeeze the horizontal section32at a bottom of the groove structure113, while the vertical section31fills between the side wall of the end cover protrusion21and the side wall of the groove structure113, to achieve a good waterproof function.

In an optional implementation, the flexible member30is provided with a notch structure311, so that when the end cover protrusion21matches the groove structure113, two opposite sides of the notch structure311can fit together to form a waterproof groove, which once again improves the waterproof performance of the outer end cover20after connection to the hub housing11.

In an optional implementation, referring toFIG. 3, one end of an upper surface of the first protrusion111away from a central axis of the wheel body10is provided with a third protrusion114, and the outer end cover20is installed on an inner side of the third protrusion114. This may not only limit the outer end cover20, but also further enhance the sealing performance between the outer end cover20and the hub housing11.

In an optional implementation, the hub housing11is provided with a fourth protrusion circumferentially arranged around the central axis of the wheel body10, the fourth protrusion forms a lamp cavity structure14for installing the light-emitting assembly60, the first optical element40, and the second optical element50, and the outer end cover20covers an opening of the lamp cavity structure14. One end of an upper surface of the fourth protrusion away from the central axis of the wheel body is provided with a fifth protrusion, the outer end cover20is installed on an inner side of the fifth protrusion, and the light-emitting assembly is arranged between the first optical element and the second optical element.

It should be noted that the fourth protrusion may be the first protrusion111or the second protrusion112, or the fourth protrusion may be a protrusion structure in which the first protrusion111and the second protrusion112are connected without a groove structure113, and the purpose is mainly to form a lamp cavity structure14with an accommodating space, and also to enable the outer end cover20to abut against an end face of the fourth protrusion or the opening of the lamp cavity structure14. The shape and size of the fourth protrusion are not limited in the present disclosure.

In addition, the fifth protrusion may be similar to the third protrusion114, and the shape and size of the fifth protrusion are not limited. The fifth protrusion is mainly a protrusion structure arranged on the fourth protrusion, so that the outer end cover20can be installed on the inner side of the fifth protrusion. This can not only limit the outer end cover20, but also further enhance the sealing performance between the outer end cover20and the hub housing11.

In an optional implementation, the hub housing11is provided with a first fixing part, the outer end cover20is provided with a first mounting part, and the outer end cover20is capable of being fixed to the hub housing11through a matching between the first mounting part and the first fixing part.

For example, referring toFIG. 5, the first fixing part is a first fixing hole annularly provided at a bottom of the hub housing11, the first mounting part is a first fixed column22annularly arranged on the outer end cover20, and the first fixed column22is clamped with the first fixing hole. A diameter of the first fixed column22gradually decreases from the joint between the first fixed column22and the outer end cover20toward a free end of the first fixed column22, and the diameter of the first fixing hole matches the diameter of the free end of the first fixed column22. This not only can ensure strength and hardness of the first fixed column22, but also enables the first fixed column22to be firmly fixed in the first fixing hole.

Alternatively, referring toFIG. 18, the first fixing part is a first clamping groove provided on the hub housing11, the first mounting part is a first buckle231arranged on the outer end cover20, and the first buckle231is clamped with the first clamping groove, to complete a fixed connection between the outer end cover20and the hub housing11. In this implementation, an annular flange23is annularly arranged on the outer end cover20, and the first buckle231is arranged on the annular flange23. In this way, not only the first buckle231can be prevented from being easily broken due to a problem of being elongated, but also the annular flange23can be used to form a waterproof wall, thereby improving the waterproof performance of the lamp cavity structure14again.

In an optional implementation, referring toFIG. 8, the wheel body10may include a lamp accommodating structure13installed in the lamp cavity structure14, a light-emitting assembly60is annularly arranged on an annular side wall of the lamp accommodating structure13, and a first optical element40and a second optical element50are installed on the lamp accommodating structure13. This requires an installation position of the light-emitting assembly60to be provided on the lamp cavity structure14, and the lamp accommodating structure13may be designed to be rotatable relative to the hub housing11or be fixed to the hub housing11as required.

For example, the light-emitting assembly60includes an LED light bar, where the annular side wall of the lamp accommodating structure13is provided with a light outlet groove133, the LED light bar is annularly arranged on the annular side wall, and lamp beads of the LED light bar are exposed from the light outlet groove133.

Specifically, referring toFIG. 9, the lamp accommodating structure13includes a lamp holder bottom131and an annular side wall annularly arranged on the lamp holder bottom131, and an end of the annular side wall away from the lamp holder bottom131is provided with a lamp holder buckle134and a lamp holder abutting table132. The first optical element40fits to the lamp holder bottom131, the second optical element50is clamped on the lamp holder abutting table132through the lamp holder buckle134, and the LED light bar is clamped on the annular side wall.

In an optional implementation, a connecting groove135may be concavely arranged on one side of the lamp holder bottom131close to the outer end cover20. Accordingly, with regard to the other side of the lamp holder bottom131away from the outer end cover20, the connecting groove135is equivalent to forming a protruding part on the other side (not shown). The protruding part may be referred to as a connecting protrusion, and the connecting protrusion may be fixedly connected to a wheel axle12on the wheel body10, for example, by using a common fixing method such as a screw.

It should be noted that the connecting protrusion is fixed to a fixed end of the wheel axle12, so that a gap region M (refer toFIG. 2) may be provided between the lamp accommodating structure13and the bottom of the lamp cavity structure14, thereby ensuring that the lamp cavity structure14or the hub housing11can rotate smoothly relative to the lamp accommodating structure13.

In this implementation, a routing groove136is connected between the connecting groove135and the annular side wall, and is used for routing arrangement of the LED light bar.

In an optional implementation, the wheel body10includes a motor15and a wheel axle12, where the motor15is arranged inside the hub housing11, for example, the lamp accommodating structure13may be fixedly connected to the wheel axle12and then located inside the hub housing11, so that the lamp accommodating structure13is fixed relative to the wheel axle12. In this way, the light-emitting assembly60on the lamp accommodating structure13and the wheel axle12are also fixed, and when the wheel100is implemented in a balance vehicle, the light-emitting assembly60can keep relatively stationary with a rider on the balance vehicle when the wheel body10rotates relative to the ground, and then countless images formed by indefinite reflections of the light-emitting assembly60through the first optical element and the second optical element are also relatively stationary with the rider.

In addition, the motor15can drive the hub housing11to rotate relative to the wheel axle12. In this implementation, the wheel axle12is provided with a routing hole121, so that a cable electrically connected to the LED light bar can pass through the routing hole121.

In an optional implementation, as shown inFIG. 22toFIG. 28, the first protrusion111is arranged on an outer side of the groove structure113, and the second protrusion112is arranged on an inner side of the groove structure113. The first protrusion111includes a first step section111aand a second step section111bwith a height greater than that of the first step section111a, and the first step section111ais arranged on one side close to the second protrusion112. The outer end cover20abuts against the first step section111aor the second protrusion112and is located on the inner side of the second step section111b. The second step section111bcan not only achieve a limiting function, but also achieve a function of a waterproof wall.

In an optional implementation, the height of the first step section111ais the same as that of the second protrusion112, so that the outer end cover20can abut against the first step section111aand the second protrusion112, while an end face of the first step section11aand an end face of the second protrusion112form a reference end face that matches the outer end cover20, and the groove structure113is provided between the first step section111aand the second protrusion112. In an optional implementation, the height of the first step section111ais the same as that of the second protrusion112, so that the groove structure113can have the same distance from the first step section111aand the second protrusion112, so that the groove structure113can be filled with some flexible members30with the same length as the first step section111aand the second protrusion112.

In an optional implementation, the height of the second step section111bis greater than that of the second protrusion112, so that the second step section111bcan achieve a limiting function and can also achieve the function of a waterproof wall.

In an optional implementation, the wheel100further includes a flexible member30with a T-shaped structure, where part of the flexible member30fills the groove structure113, and the other part of the flexible member30is located on the second step section111band the second protrusion112. The flexible member30filling the groove structure113achieves a function of fixing the flexible member30, while the flexible member30located on the second step section111band the second protrusion112is configured to abut against the outer end cover20, to achieve a waterproof function.

For example, the flexible member30includes a fixed section33and an abutting section34. The abutting section34extends from two ends of the fixed section33to form a T-shaped structure, where the fixed section33fills the groove structure113, and the abutting section34is located on the second step section111band the second protrusion112, and is configured to fill gaps between the outer end cover20and the second step section111band the second protrusion112.

In an optional implementation, referring to the foregoing similar description of the present disclosure, the ratio of the height H1of the second protrusion112to the average width L1of the groove structure113is greater than 1.6 and less than 1.8, so as to ensure the strength of the second protrusion112or the second step section111b, and the fixed section33can be firmly fixed in the groove structure113.

In an optional implementation, the light-emitting assembly60may include an LED light bar, where the LED light bar is annularly arranged inside the lamp cavity structure14. For example, the inside or bottom of the lamp cavity structure14may include an annular light bar mounting wall119, and the light-emitting assembly60may be mounted on an inner side wall of the light bar mounting wall119. Herein, the inner side wall may refer to a side wall of the light bar mounting wall119close to the central axis of the lamp cavity structure14.

In addition, the LED light bar is connected to a wheel axle electrode122in the wheel body10through a conductive sheet16arranged on the lamp cavity structure14, so as to ensure that the LED light bar can be electrically connected to the vehicle body through a connection and matching between the conductive sheet16and the wheel axle electrode122. In addition, the LED light bar can rotate relative to the wheel axle12.

In an optional implementation, the wheel body10includes a wheel axle12and a conductive sheet16, where the bottom of the lamp cavity structure14is provided with an electrode mounting groove, the wheel axle12is provided with an electrode (which may be understood as a conductive terminal), and the conductive sheet16is fixed in the electrode mounting groove and abuts against an electrode and is not only simple in structure, but also convenient to install. It should be noted that the shape and material of the conductive sheet16are not limited, for example, the conductive sheet may be a sheet with certain elasticity.

In an optional implementation, one side of the outer end cover20that faces away from the lamp cavity structure14is provided with an outer cover protrusion24, and the outer cover protrusion24can prevent a surface of the outer end cover20from being scratched when the outer end cover20collides or is placed vertically. In addition, in the process of forming the outer end cover20by using a mold, the end cover protrusion21or the first fixed column22is arranged on the inner side of the outer end cover20. This easily makes the outer end cover20sunken. However, the plastic sinking problem can be solved by the outer cover protrusion24in the present disclosure.

In an optional implementation, the outer cover protrusion24includes at least two reinforcing ribs arranged at intervals, and two reinforcing ribs are annularly arranged at positions of the outer cover protrusion24close to edges. This can increase the strength of the outer end cover20. In addition, when the wheel body10collides, a breakage accident does not occur easily since the at least two reinforcing ribs are provided.

In an optional implementation, the width of the outer cover protrusion24is 0.3-2.3 mm, which does not affect the appearance of the outer end cover20, and can prevent a surface of the outer end cover20from being scratched when the outer end cover20collides or is placed vertically.

As shown inFIG. 1toFIG. 28, according to a second aspect of the present disclosure, the present disclosure provides a scooter, which may include a frame and the foregoing wheels100, where the wheels100may be installed on two sides of the frame.

It should be noted that the types of scooters are not limited, for example, the scooters may include a balance vehicle, a go-kart, a kick scooter, a hoverboard, an electric vehicle, and the like.
