Description

Technical Field

[0001] This utility model relates to the field of vehicle-related technology, specifically to a shock-absorbing wheel and a scooter. Background Technology

[0002] In current electric vehicle hub motor designs, the motor rotor assembly is directly embedded in the wheel hub. While this structure simplifies the assembly process, it has significant limitations in real-world usage. Electric vehicles inevitably encounter uneven road surfaces during operation, generating vibrations. Although tires themselves provide some cushioning and absorb some vibration energy, a significant amount of vibration is still directly transmitted to the hub motor. This problem is particularly pronounced in the hub motor rotor assembly because traditional designs lack effective internal vibration damping measures, leading to a significant decrease in the motor's performance and lifespan after prolonged exposure to vibration.

[0003] Specifically, existing electric vehicle hub motors typically design the rotor assembly to be tightly connected to the wheel hub without dedicated vibration damping. This design means that vibrations directly act on the motor rotor when facing complex road conditions, causing several problems: Vibration transmission: Vibration energy is directly transferred from the wheel hub to the rotor assembly, reducing motor stability, especially at high speeds or on rough roads. Reduced lifespan: Long-term vibration not only reduces motor efficiency but also accelerates the wear of internal components in the rotor assembly, thus shortening the overall lifespan of the motor. Performance fluctuations: Vibration can also lead to unstable motor performance, potentially affecting the electric vehicle's driving experience, such as generating noise and reducing power response speed.

[0004] As a result, the wheels of existing scooters have poor shock absorption performance, which affects their performance. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a shock-absorbing wheel and a scooter.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] One aspect of this application provides a shock-absorbing wheel, comprising an inner hub, an outer hub, a connecting structure, and a shock absorber. The outer hub is disposed outside the inner hub, and the connecting structure is disposed between the inner and outer hubs, connecting the inner and / or outer hubs. The connecting structure has mounting holes, and the shock absorber is disposed between the inner and outer hubs, respectively fitting against them. A portion of the shock absorber is disposed within the mounting holes. This application utilizes the placement of the shock absorber in the connection area between the inner and outer hubs. This placement effectively absorbs and disperses vibrations and impacts encountered by the shock-absorbing wheel during driving, significantly improving the stability and service life of the structural components mounted on the inner hub. Furthermore, the placement of a portion of the shock absorber within the mounting holes creates a positioning installation for the shock absorber, while also strengthening the structural stability of the inner hub, shock absorber, and outer hub, ensuring that the shock absorber does not shift during wheel rotation.

[0008] In some embodiments, an annular mounting area is formed between the outer and inner wheel hubs, and the shock absorber fills the mounting area and wraps around the connecting structure. By forming an annular mounting area, this application ensures that the shock absorber is evenly distributed, thereby providing a consistent damping effect across the entire circumference of the wheel. The filling and wrapping action of the shock absorber maximizes its contact area with the inner and outer wheel hubs, improving damping efficiency. Simultaneously, the technical solution in this application ensures that vibrations in any direction are effectively buffered, improving the structural stability of the shock-absorbing wheel.

[0009] In some embodiments, the damping element is a colloid, and the damping element fills the installation area through an overmolding process. This application uses a colloid as the damping material, leveraging its excellent elastic properties and the convenience of the overmolding process to achieve rapid installation and reliable fixation of the damping element. The elastic deformation of the colloid material effectively absorbs vibration energy, while the overmolding process ensures a tight bond between the damping element and the connecting structure, preventing detachment during use. Furthermore, the technical solution in this application provides a durable damping effect while simplifying the manufacturing process and reducing costs.

[0010] In some embodiments, the connecting structure extends circumferentially along the outer hub, and at least one mounting hole is provided. When multiple mounting holes are provided, they are spaced apart along the extending direction of the connecting structure. This application ensures a uniform distribution of the shock absorber on the wheel circumference by extending the connecting structure circumferentially and spaced the mounting holes, thus improving the consistency of the shock absorption effect. The spaced mounting holes prevent stress concentration in the shock absorber when the wheel rotates, thereby increasing the service life of the shock absorber.

[0011] In some embodiments, the connecting structure is a ring structure; or the connecting structure is one or more arc-shaped plate structures. When the connecting structure is multiple arc-shaped plate structures, the multiple arc-shaped plate structures are spaced apart along the circumference of the outer hub, and each arc-shaped plate structure is provided with at least one mounting hole. In this application, the connecting structure can be a ring structure, which is adapted to the ring-shaped shock absorber. The multiple mounting holes form multiple positioning points for the shock absorber, ensuring the stability of the shock absorber's positioning. The arc-shaped top plate structure facilitates fitting with the shock absorber and thus positioning the shock absorber, thereby improving the stability of the shock absorber's positioning.

[0012] In some embodiments, the mounting hole is a circular hole, a polygonal hole, an elliptical hole, or a waist-shaped hole arranged along the circumference of the outer hub. The mounting hole in this application can have a variety of different shaped slot structures, which helps to improve the adaptability of the mounting hole to different installation scenarios and increases the flexibility of the structural design.

[0013] In some embodiments, the connecting structure includes a first plate and a second plate arranged at an angle. Along the radial direction of the outer hub, a first end of the first plate is connected to the inner hub and / or the outer hub, and a second plate is disposed at a second end of the first plate. Mounting holes are provided on the first plate and / or the second plate. In this application, the first plate is fixed to the inner hub and / or the outer hub and positioned in contact with the damper, while the second plate is positioned in contact with the damper. The structural arrangement of the first and second plates positions the damper in two directions, improving the stability of the damper installation and thus ensuring the damping effect.

[0014] In some embodiments, the first plate and the second plate are perpendicular; and / or the first plate is an annular structure and coaxial with the outer wheel hub. This application, through the perpendicular arrangement of the first and second plates and the coaxial design of the first plate with the outer wheel hub, aims to improve the strength and stability of the connection structure while ensuring the uniform distribution of the shock absorbers. The perpendicular arrangement of the first and second plates provides a more stable force transmission path, while the coaxial design ensures the uniform distribution of the shock absorbers on the wheel circumference, improving the consistency of the shock absorption effect. This application ensures that the shock-absorbing wheel guarantees driving safety and comfort when traveling at high speeds or encountering complex road conditions.

[0015] In some embodiments, the second plate is an annular plate disposed between the inner and outer hubs, with a gap between the second plate and the outer circumferential surface of the inner hub, and a damping element disposed inside the gap; or the first plate is connected to the outer circumferential surface of the inner hub, and the second plate is an annular plate disposed between the first and second plates, with a gap between the second plate and the inner circumferential surface of the outer hub, and a damping element disposed inside the gap. This application uses a damping element disposed inside the gap to form a damping layer. The damping layer absorbs vibrations and reduces force transmission, thereby increasing the damping effect; simultaneously, the damping layer can also fully enclose the connecting structure, thereby improving the stability of the damping element's positioning and installation.

[0016] In some embodiments, a connecting structure is disposed on one of the inner hub and the outer hub, and the other of the inner hub and the outer hub is provided with two annular flanges spaced axially apart, the flanges extending toward the area between the inner hub and the outer hub, and at least a portion of the damping member is embedded between the two flanges. This application achieves the fixation of the damping member by embedding a portion of it between the two flanges, thereby ensuring the stability of the damping member during installation between the inner hub and the outer hub.

[0017] In some embodiments, the extension height of the flange along the radial direction of the outer hub is not less than the length of the gap. The flange height being greater than the gap length further ensures the stability of the damper installation; wherein the gap is formed as a radially positioned damper, and the two flanges are formed as an axially positioned damper. The gap and flanges ensure the stability of the damper's positioning and installation, thereby guaranteeing the damping effect.

[0018] Another aspect of this application provides a scooter that includes the aforementioned shock-absorbing wheels. The scooter of this application has shock-absorbing wheels that absorb vibrations during riding, thereby improving riding comfort and extending the scooter's lifespan.

[0019] This utility model has the following beneficial effects:

[0020] This application employs a shock absorber installed in the connection area between the inner and outer wheel hubs. The installation of the shock absorber effectively absorbs and disperses the vibrations and impacts encountered by the shock-absorbing wheel during driving, significantly improving the installation stability and service life of the structural components installed on the inner wheel hub. This application also uses a portion of the shock absorber to form a mounting hole inside, which forms the positioning and installation of the shock absorber. At the same time, it strengthens the structural stability of the inner wheel hub, shock absorber, and outer wheel hub, ensuring that the shock absorber will not shift when the shock-absorbing wheel rotates.

[0040] To address the problem of poor shock absorption performance in existing scooter wheels, which affects usability, this application provides a shock-absorbing wheel that is used in electric vehicles.

[0041] Specifically, the electric vehicle is an electric scooter.

[0042] like Figures 1 to 8 As shown, the shock-absorbing wheel includes an inner hub 10, an outer hub 20, a connecting structure 30, and a shock absorber 40. The outer hub 20 is located on the outside of the inner hub 10. The connecting structure 30 is located between the inner hub 10 and the outer hub 20 and is connected to the inner hub 10 and / or the outer hub 20. The connecting structure 30 has a mounting hole 301. The shock absorber 40 is located between the inner hub 10 and the outer hub 20 and is respectively attached to the inner hub 10 and the outer hub 20. A portion of the shock absorber 40 is located in the mounting hole 301.

[0043] The connecting structure 30 can be one or multiple. When there is one connecting structure 30, it can be located on the outer circumferential surface of the inner hub 10 or the inner circumferential surface of the outer hub 20. When there are multiple connecting structures 30, they can all be located on the inner hub 10 or the outer hub 20, or some of the connecting structures 30 can be located on the inner hub 10 and the other part can be located on the outer hub 20.

[0044] Specifically, during the use of the shock-absorbing wheel, the vibration received by the outer hub 20 is first transmitted to the shock absorber 40 that is in contact with it, and then to the inner hub 10. Since the shock absorber 40 is designed to absorb vibration, it can reduce vibration and thus ensure the stability of the installation of the shock-absorbing wheel.

[0045] This application employs a shock absorber 40 installed in the connection area between the inner hub 10 and the outer hub 20. The installation of the shock absorber 40 effectively absorbs and disperses the vibrations and impacts encountered by the shock-absorbing wheel during driving, significantly improving the installation stability and service life of structural components installed on the inner hub 10. For example, for a motor installed on the inner hub 10, the installation of the shock absorber 40 reduces vibration, thereby ensuring the stability of motor installation and operation. This application also uses a portion of the shock absorber 40 to form the internal structure of the mounting hole 301, which forms the positioning installation of the shock absorber 40. This also strengthens the structural stability of the inner hub 10, the shock absorber, and the outer hub 20, ensuring that the shock absorber 40 will not shift when the shock-absorbing wheel rotates.

[0046] like Figures 1 to 4 As shown, an annular mounting area 50 is formed between the outer hub 20 and the inner hub 10. The shock absorber 40 is disposed inside the mounting area 50 and fits against the inner hub 10 and the outer hub 20.

[0047] Specifically, the shock absorber 40 fills the installation area 50 and wraps the connecting structure 30.

[0048] This application ensures that the shock absorber 40 is evenly distributed by forming an annular installation area 50, thereby providing a consistent shock absorption effect across the entire circumference of the wheel. The filling and wrapping effect of the shock absorber 40 maximizes its contact area with the inner hub 10 and the outer hub 20, improving shock absorption efficiency. At the same time, the technical solution in this application ensures that vibrations in any direction of the shock-absorbing wheel are effectively buffered, improving the structural stability of the shock-absorbing wheel.

[0049] The shock absorber 40 of this application uses a shock-absorbing material to absorb vibrations and achieve a damping effect. In this embodiment, the shock absorber 40 is a colloid, and it fills the installation area 50 through an adhesive coating process. This application uses a colloid as the shock absorber material, leveraging its good elastic properties and the convenience of the adhesive coating process to achieve rapid installation and reliable fixation of the shock absorber 40. The elastic deformation of the colloid material effectively absorbs vibration energy, while the adhesive coating process ensures a tight bond between the shock absorber 40 and the connecting structure 30, preventing detachment during use. Furthermore, the technical solution in this application provides a durable damping effect while simplifying the manufacturing process and reducing costs.

[0050] It should be noted that, in addition to the above-mentioned colloids, other damping materials similar to colloids, such as foam, can also be used in other embodiments.

[0051] like Figures 5 to 8 As shown, the connecting structure 30 extends circumferentially along the outer hub 20, and at least one mounting hole 301 is provided.

[0052] The mounting hole 301 can be provided as one or multiple. When there are multiple mounting holes 301, they are spaced apart along the extension direction of the connecting structure 30.

[0053] In this embodiment, the plurality of mounting holes 301 may be equally spaced along the extension direction of the connecting structure 30.

[0054] This application ensures the uniform distribution of the shock absorber 40 on the circumference of the wheel by extending the connecting structure 30 circumferentially and spaced the mounting holes 301, thereby improving the consistency of the shock absorption effect. The spaced mounting holes 301 prevent stress concentration in the shock absorber 40 when the wheel rotates, thus improving the service life of the shock absorber 40.

[0055] Specifically, the connecting structure 30 can be a ring structure. The connecting structure 30 is coaxial with the inner hub 10 and the outer hub 20. The ring structure 30 is adapted to the ring-shaped shock absorber 40. The ring-shaped contact area formed by the connecting structure 30 and the shock absorber 40 ensures the stability of the shock absorber 40. Furthermore, the multiple mounting holes 301 form multiple positioning points for the shock absorber 40, further ensuring the stability of the positioning of the shock absorber 40.

[0056] Specifically, the connecting structure 30 can be an arc-shaped plate structure. The arc-shaped plate structure is conducive to fitting and positioning the shock absorber 40, thereby improving the positioning stability of the shock absorber 40. At the same time, the mounting holes 301 on the arc-shaped plate structure form the positioning points of the shock absorber 40, ensuring the positioning stability of the shock absorber 40.

[0057] The arc-shaped plate structure can be one or multiple. When multiple arc-shaped plate structures are provided, they are spaced apart circumferentially along the outer hub 20, and each arc-shaped plate structure has at least one mounting hole 301. The structure with multiple arc-shaped plates spaced apart enables the regional positioning of the damping component 40.

[0058] In this embodiment, the mounting hole 301 can be adaptively configured as needed. For example, the mounting hole 301 can be a circular hole, a polygonal hole, an elliptical hole, or a waist-shaped hole arranged circumferentially along the outer hub 20. The mounting hole 301 of this application can have various different shaped slot structures, which is beneficial to improving the adaptability of the mounting hole 301 to different installation scenarios and improving the flexibility of the structural configuration.

[0059] like Figure 8 As shown, the connection structure 30 includes a first plate 310 and a second plate 320 arranged at an angle. Along the radial direction of the outer hub 20, the first end of the first plate 310 is connected to the inner hub 10 and / or the outer hub 20, and the second plate 320 is disposed at the second end of the first plate 310. The first plate 310 and / or the second plate 320 are provided with mounting holes 301.

[0060] The first plate 310 can be connected to the inner hub 10 or the outer hub 20. When there are multiple connecting structures 30, the first plate 310 of one connecting structure 30 can be connected to the inner hub 10, and the first plate 310 of another connecting structure 30 can be connected to the outer hub 20.

[0061] The first plate 310 of this application is fixed to the inner hub 10 and / or the outer hub 20 and is positioned in contact with the shock absorber. The second plate 320 is positioned in contact with the shock absorber 40. The structural arrangement of the first plate 310 and the second plate 320 positions the shock absorber 40 in two directions, which improves the stability of the installation of the shock absorber 40 and thus ensures the shock absorption effect.

[0062] In this embodiment, the first plate 310 and the second plate 320 are perpendicular.

[0063] In this embodiment, the first plate 310 has an annular structure and is coaxial with the inner hub 10 and the outer hub 20.

[0064] This application, through the vertical arrangement of the first plate 310 and the second plate 320, and the coaxial design of the first plate 310 and the outer wheel hub 20, aims to improve the strength and stability of the connecting structure 30, while ensuring the uniform distribution of the shock absorbers 40. The vertical arrangement of the first plate 310 and the second plate 320 provides a more stable force transmission path, while the coaxial design ensures the uniform distribution of the shock absorbers 40 on the wheel circumference, improving the consistency of the shock absorption effect. This application can ensure the driving safety and comfort of the shock-absorbing wheel when driving at high speeds or encountering complex road conditions.

[0065] In one specific implementation of this embodiment, such as Figures 5 to 8 As shown, the connecting structure 30 is disposed on the outer hub 20.

[0066] Specifically, the first plate 310 is connected to the inner circumferential surface of the outer hub 20, and the second plate 320 is an annular plate disposed between the inner hub 10 and the outer hub 20. The second plate 320 and the outer circumferential surface of the inner hub 10 are spaced apart to form a gap 120, and a shock absorber 40 is disposed inside the gap 120.

[0067] This application uses a damping element 40 to form a damping layer inside the gap 120. The damping layer absorbs vibration and reduces the transmission of force, thereby increasing the damping effect. At the same time, the damping layer can also fully enclose the connecting structure 30, thereby improving the stability of the positioning and installation of the damping element 40.

[0068] In this embodiment, the connecting structure 30 is disposed on the outer hub 20, and the inner hub 10 is provided with two flanges 110 that are axially spaced apart. The flanges 110 extend toward the area between the inner hub 10 and the outer hub 20, and the flanges 110 are formed into annular shapes along the circumference of the inner hub 10. At least a portion of the shock absorber 40 is embedded between the two annular flanges 110.

[0069] Two flanges 110 are respectively disposed at corresponding positions on the two end faces of the inner hub 10, so that a sufficiently large mounting area 50 is formed between the two flanges 110 along the axial direction of the inner hub 10 to mount the shock absorber 40, thereby improving the stability of the connection between the inner hub 10 and the shock absorber 40.

[0070] This application achieves the fixation of the shock absorber 40 by embedding a portion of the shock absorber 40 between the two flanges 110, thereby ensuring the stability of the shock absorber 40 when installed between the inner hub 10 and the outer hub 20.

[0071] Along the radial direction of the outer hub 20, the extension height of the flange 110 is not less than the length of the gap 120. The fact that the height of the flange 110 is greater than the length of the gap 120 further ensures the stability of the damper 40 installation; wherein the gap 120 forms a radially positioned damper 40, and the two flanges 110 form an axially positioned damper 40, the gap 120 and the flanges 110 ensure the stability of the damper 40's positioning and installation, thereby guaranteeing the damping effect.

[0072] In another specific embodiment of this example, as shown in the figure, the connecting structure 30 is disposed on the inner hub 10.

[0073] Specifically, the first plate 310 is connected to the outer peripheral surface of the inner hub 10, and the second plate 320 is an annular plate disposed between the first plate 310 and the second plate 320. The second plate 320 and the inner peripheral surface of the outer hub 20 are spaced apart to form a gap 120, and a shock absorber 40 is disposed inside the gap 120.

[0074] This application uses a damping element 40 to form a damping layer inside the gap 120. The damping layer absorbs vibration and reduces the transmission of force, thereby increasing the damping effect. At the same time, the damping layer can also fully enclose the connecting structure 30, thereby improving the stability of the positioning and installation of the damping element 40.

[0075] In this embodiment, the connecting structure 30 is disposed on the inner hub 10, and the outer hub 20 is provided with two flanges 110 that are axially spaced apart. The flanges 110 extend toward the area between the inner hub 10 and the outer hub 20, and the flanges 110 are formed into annular shapes along the circumference of the outer hub 20. At least a portion of the shock absorber 40 is embedded between the two annular flanges 110.

[0076] Two flanges 110 are respectively disposed at corresponding positions on the two end faces of the outer hub 20, so that a sufficiently large mounting area 50 is formed between the two flanges 110 along the axial direction of the inner hub 10 to mount the shock absorber 40, thereby improving the stability of the connection between the inner hub 10 and the shock absorber 40.

[0077] This application achieves the fixation of the shock absorber 40 by embedding a portion of the shock absorber 40 between the two flanges 110, thereby ensuring the stability of the shock absorber 40 when installed between the inner hub 10 and the outer hub 20.

[0078] Along the radial direction of the outer hub 20, the extension height of the flange 110 is not less than the length of the gap 120. The fact that the height of the flange 110 is greater than the length of the gap 120 further ensures the stability of the damper 40 installation; wherein the gap 120 forms a radially positioned damper 40, and the two flanges 110 form an axially positioned damper 40, the gap 120 and the flanges 110 ensure the stability of the damper 40's positioning and installation, thereby guaranteeing the damping effect.

[0079] During operation, when the scooter is in motion, the shock-absorbing wheel vibrates when encountering uneven road surfaces. The shock-absorbing wheel of this application, by incorporating a connecting structure 30 and a shock absorber 40 between the inner hub 10 and the outer hub 20, effectively absorbs and disperses vibration energy, reducing the impact of vibration on structural components on the inner hub 10, such as the motor. The elastic deformation characteristics of the shock absorber 40 absorb vibration, while the connecting structure 30 ensures the stable fixation of the shock absorber 40, preventing displacement during high-speed rotation of the shock-absorbing wheel. In use, the shock-absorbing wheel of this application provides a more stable and comfortable riding experience, especially on uneven roads or at high speeds, significantly reducing vibration, protecting the motor from damage, and extending the service life of the electric vehicle or scooter. Furthermore, by adjusting the material, shape, and hardness of the shock absorber 40, and the design of the connecting structure 30, the technical solution of this application can adapt to different usage environments and load conditions, providing optimal shock absorption.

[0080] In other embodiments, this application also provides a scooter that includes the shock-absorbing wheels described above.

[0081] Specifically, the scooter also includes a motor, which is mounted on the inner hub 10 of the shock-absorbing wheel.

[0082] In this embodiment, the shock-absorbing wheels can absorb vibrations during the scooter's operation, thereby improving the riding comfort and lifespan of the scooter.

[0083] This utility model has the following beneficial effects:

[0084] This application employs a shock absorber 40 installed in the connection area between the inner hub 10 and the outer hub 20. The installation of the shock absorber 40 effectively absorbs and disperses the vibrations and impacts encountered by the shock-absorbing wheel during driving, significantly improving the stability and service life of the structural components installed on the inner hub 10. This application also uses a portion of the shock absorber 40 to form the internal structure of the mounting hole 301, thereby enhancing the stability of the structural installation of the inner hub 10, the shock absorber, and the outer hub 20, ensuring that the shock absorber 40 will not shift when the shock-absorbing wheel rotates.
