Description

Technical Field

[0001] This utility model relates to the field of skateboard wheel hub technology, specifically a dirt-proof electric skateboard wheel hub. Background Technology

[0002] With the widespread use of electric scooters for urban commuting and short-distance travel, their operating environment is becoming increasingly complex. During operation, the drive wheels of electric scooters are in direct contact with the ground, making them susceptible to contamination from mud, dust, and water stains. Over time, these stains accumulate on the surface of the drive wheels, affecting not only the vehicle's stability but also accelerating the wear and tear on the motor and related transmission components.

[0003] In existing technologies, some electric scooters only have simple mudguards on the outside of the wheels to prevent mud and water splashes, but they cannot actively clean the wheel surface, thus limiting their cleaning effectiveness. Some electric vehicles also have fixed brush strip structures installed on the bottom of the vehicle body, which remove some stains by contacting the brush bristles with the wheel surface. However, these fixed brush strips are limited by the installation angle and pressure, resulting in a limited cleaning range and difficulty in adapting to the different stain conditions on the wheel surface, leading to low cleaning efficiency.

[0004] Furthermore, traditional drive wheel sets typically use external rotor motors or metal hubs, which are prone to accumulating mud and grime. Due to the lack of a dedicated anti-fouling coating, even with brush cleaning, incomplete cleaning and easy re-contamination of the wheel surface remain issues. Additionally, existing cleaning structures are mostly fixed installations without detachable features, leading to brush wear and difficulty in replacement after a period of use, increasing maintenance costs.

[0005] Therefore, how to propose a new drive wheel structure that can achieve self-cleaning of the wheel hub, protection with anti-fouling coating, and improved maintainability during the operation of electric scooters has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is: a dirt-proof electric scooter wheel hub, which, by setting a wheel fork seat, a drive wheel assembly and a self-cleaning component, enables the drive wheel assembly to achieve self-cleaning and dirt-proof functions when rotating, thereby improving the operating safety and durability of the electric scooter.

[0008] In a preferred example, the anti-fouling electric skateboard wheel hub includes a fork seat, a drive wheel assembly, and a self-cleaning component. The drive wheel assembly is rotatably mounted on the bottom of the fork seat, and fork lugs are provided on both sides of the fork seat, with grooves formed on the surface of the fork lugs. The self-cleaning component includes a flexible telescopic rod, a hub cover, a brush strip, and a connecting rod. The flexible telescopic rod is mounted on both sides of the fork seat, and a sliding pin is fixedly mounted on its output end. The hub cover has rotating lugs on both sides, which are rotatably fitted onto the surface of the sliding pin. The two ends of the connecting rod are rotatably connected to the surfaces of the fork lugs and the hub cover, respectively. The brush strip is detachably mounted on the bottom end of the hub cover and slides against the surface of the drive wheel assembly. Specifically, this structure can clean the wheel surface and remove adhering dust and impurities when the drive wheel assembly rotates.

[0009] In a preferred embodiment, the elastic telescopic rod is further configured such that it is arranged vertically on both sides of the wheel fork seat, and the sliding pin at the end of the elastic telescopic rod is slidably sleeved on the inner side of the groove. Specifically, this structure allows the sliding pin to guide movement within the groove, thereby ensuring that the hub cover and brush strip stably conform to the wheel surface of the drive wheel assembly, improving the cleaning effect.

[0010] In a preferred embodiment, the hub covers are symmetrically arranged on both sides of the wheel fork seat, and the ends of the hub covers on both sides are rotatably fitted onto the surface of the sliding pin shaft via lugs. Specifically, this structure can form a cover on both sides of the drive wheel assembly, with the brush strips symmetrically abutting the wheel surface, effectively enhancing the overall anti-fouling and self-cleaning effect.

[0011] In a preferred embodiment, the brush strip is further configured as a flexible brush strip arranged along the arcuate edge of the hubcap, with its bristle tips abutting against the wheel surface of the drive wheel assembly. Specifically, this design enables continuous friction against the wheel surface during the rotation of the drive wheel assembly, effectively removing dirt, dust, and water stains.

[0012] In a preferred embodiment, the elastic telescopic rod is further configured as an electric push rod or a spring rod structure, capable of outputting a push to displace the sliding pin shaft. Specifically, this structure can achieve dynamic control of the brush strip contact pressure through an electric push rod, or achieve continuous contact through a spring rod, ensuring the stability of the cleaning process.

[0013] In a preferred embodiment, the drive wheel assembly is further configured such that it includes an outer rotor motor and a wheel sleeve fitted around the outer periphery of the outer rotor motor rotor, the surface of which is provided with an anti-fouling coating. Specifically, this design reduces the adhesion strength of stains on the wheel sleeve surface, allowing the brush strip to remove residual stains more efficiently during contact, further improving self-cleaning performance.

[0014] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting elastic telescopic rods, hub covers and brush strips on both sides of the wheel fork seat, the wheel surface is cleaned in real time during the rotation of the drive wheel assembly, effectively removing mud, dust and water stains, ensuring the long-term cleanliness of the wheel hub, thereby improving the driving stability and safety of the electric scooter.

[0015] 2. In this utility model, the drive wheel assembly adopts an external rotor motor combined with an anti-fouling coating structure and a detachable brush strip design, which not only reduces the adhesion strength of stains and improves self-cleaning efficiency, but also facilitates later maintenance and replacement, significantly extending the service life of the drive wheel assembly and reducing vehicle maintenance costs.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a dirt-resistant electric skateboard wheel hub.

[0021] Combination Figures 1-4 As shown, the present invention provides a dirt-resistant electric skateboard wheel hub, including a wheel fork seat 100, a drive wheel assembly 200, and a self-cleaning component 300.

[0022] The drive wheel assembly 200 is rotatably mounted on the bottom of the wheel fork seat 100. Fork lugs 110 are provided on both sides of the wheel fork seat 100, and the surface of the fork lugs 110 is provided with sliding grooves 120. The drive wheel assembly 200 and the wheel fork seat 100 are reliably supported by rotational mounting to ensure the rotational stability of the drive wheel assembly 200.

[0023] The self-cleaning component 300 includes an elastic telescopic rod 310, a hub cover 320, a brush strip 330, and a connecting rod 340. The elastic telescopic rod 310 is installed on both sides of the wheel fork seat 100, and a sliding pin shaft 311 is fixedly installed at its output end. The hub cover 320 has rotating ears 321 on both sides, which are rotatably sleeved on the surface of the sliding pin shaft 311, so that the hub cover 320 can swing or move closer with the movement of the sliding pin shaft 311. The two ends of the connecting rod 340 are rotatably connected to the surface of the fork ear 110 and the surface of the hub cover 320, respectively, for transmitting the displacement force of the wheel fork seat 100 to the hub cover 320, forming a contact action with the drive wheel assembly 200. The brush strip 330 is detachably installed at the bottom of the hub cover 320, and the bristle end of the brush strip 330 slides against the surface of the drive wheel assembly 200 to remove dust and impurities adhering to the wheel surface, thereby keeping the drive wheel assembly 200 clean.

[0024] In a preferred embodiment, the elastic telescopic rod 310 is arranged vertically on both sides of the wheel fork seat 100, and the sliding pin 311 at the end of the elastic telescopic rod 310 is slidably sleeved on the inner side of the slide groove 120. This structural arrangement allows the sliding pin 311 to move up and down within the slide groove 120, ensuring that the hub cover 320 and the brush strip 330 can stably conform to the outer surface of the drive wheel assembly 200.

[0025] In a preferred embodiment, the hub covers 320 are symmetrically arranged on both sides of the wheel fork seat 100, and the ends of the hub covers 320 on both sides are rotatably sleeved onto the surface of the sliding pin shaft 311 via the swivel lugs 321. The symmetrical arrangement of the hub covers 320 provides full coverage protection on both sides of the drive wheel assembly 200, effectively enhancing the self-cleaning effect.

[0026] In a preferred embodiment, the brush strip 330 is a flexible brush strip arranged along the arcuate edge of the hub cover 320, with its bristle tips in contact with the wheel surface of the drive wheel assembly 200. The flexible brush strip can continuously rub and clean the wheel surface as the drive wheel assembly 200 rotates, removing dust, dirt, and water stains.

[0027] In a preferred embodiment, the elastic telescopic rod 310 is an electric push rod or a spring rod structure, capable of outputting a push to displace the sliding pin shaft 311. Under the drive of the electric push rod, the contact pressure between the brush strip 330 and the drive wheel assembly 200 can be dynamically adjusted; under the drive of the spring rod, the brush strip 330 and the drive wheel assembly 200 can be continuously fitted together under the action of elastic restoring force.

[0028] In a preferred embodiment, the drive wheel assembly 200 includes an outer rotor motor and a wheel sleeve fitted around the outer periphery of the rotor of the outer rotor motor. The surface of the wheel sleeve is provided with an anti-fouling coating. The anti-fouling coating can reduce the adhesion strength of stains on the surface of the wheel sleeve, thereby making the brush strip 330 more efficient in cleaning and further improving the self-cleaning effect.

[0029] In summary, this utility model achieves active cleaning of the wheel surface during the rotation of the drive wheel assembly 200 through the synergistic effect of the wheel fork seat 100, the drive wheel assembly 200, and the self-cleaning component 300. This not only ensures the driving stability and safety of the electric scooter but also reduces the maintenance frequency and usage cost.

[0030] Working principle and usage process of this utility model: The anti-fouling electric scooter wheel hub of this utility model achieves automatic cleaning of the wheel surface of the drive wheel assembly 200 during the scooter's operation through the coordinated cooperation of the wheel fork seat 100, the drive wheel assembly 200, and the self-cleaning component 300.

[0031] In the working state, the drive wheel assembly 200 is installed at the bottom of the wheel fork seat 100, and the fork lugs 110 on both sides provide guiding support for the connecting rod 340 and sliding pin shaft 311 of the self-cleaning assembly 300 through the internal sliding groove 120.

[0032] When the elastic telescopic rod 310 is activated, the sliding pin 311 at its output end is displaced along the sliding groove 120, causing the rotating ear 321 and the hub cover 320 to move relative to each other. The hub cover 320 covers the outer periphery of the drive wheel assembly 200, and the brush strip 330 at its bottom end slides against the wheel surface of the drive wheel assembly 200 under the action of the elastic telescopic rod 310, thereby removing dirt, dust and water stains from the wheel surface in real time.

[0033] During driving, the symmetrically arranged hub covers 320 on both sides can form a surrounding coverage of the drive wheel assembly 200, while the brush strips 330 continuously contact the wheel surface in the form of flexible brushes to achieve dynamic cleaning of the wheel body and prevent the long-term accumulation of dirt from affecting driving stability.

[0034] The elastic telescopic rod 310 can be an electric push rod or a spring rod structure. Its telescopic displacement can adjust the contact pressure between the brush strip 330 and the drive wheel assembly 200 in real time, which can ensure the cleaning effect and avoid excessive friction on the wheel surface.

[0035] Furthermore, the drive wheel assembly 200 adopts an external rotor motor structure, and the outer circumference of the wheel sleeve is provided with an anti-fouling coating, which can reduce the adhesion of dirt and water stains, making the cleaning process of the brush strip 330 more efficient.

[0036] In summary, this utility model, through the cooperation of the elastic telescopic rod 310, hub cover 320, brush strip 330 and connecting rod 340, enables the drive wheel assembly 200 to remain clean during operation, effectively improving the operational stability and durability of the electric scooter, while reducing maintenance costs.
