[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] In order to understand the impact of bumps on the user experience and service life of electric scooters, please refer to Figure 1-Figure 3 The shock-absorbing mechanism for an electric scooter provided in this embodiment can effectively reduce the impact of road vibrations on the rider, making the ride smoother, significantly reducing the bumpy feeling, and making the rider feel more comfortable. The mechanism includes a wheel axle 1, which is used to support the wheel of the electric scooter. A shock-absorbing assembly 2 for shock absorption is provided on the wheel axle 1. Before using the electric scooter, the shock-absorbing assembly 2 is installed on the wheel axle 1. The shock-absorbing assembly 2 can effectively reduce the impact of road vibrations on the rider, making the ride smoother, significantly reducing the bumpy feeling, and making the rider feel more comfortable. The impact force on the wheel is reduced, and damage to components such as the scooter frame, motor, and battery is reduced. The degree of wear is reduced, thereby extending the service life of the vehicle.

[0024] Because electric scooters typically travel on various surfaces, such as urban roads and sidewalks, uneven surfaces can cause significant vibrations and bumps for riders, affecting riding comfort. Strong vibrations can also damage the scooter's components, reducing the vehicle's service life. Therefore, it is necessary to provide a shock-absorbing system to counteract the bumps and vibrations generated by the electric scooter's ride. The shock-absorbing assembly 2 includes a mounting plate 21 that can be removably mounted on the frame. The mounting plate 21 is designed to match the shape of the electric scooter's frame, and its mounting position can be adjusted based on the electric scooter's structure and design requirements to achieve optimal shock absorption. The mounting plate 21 serves as a carrier for connecting to the electric scooter's frame. A hydraulic damper 22 is fixedly connected to the mounting plate 21. A connecting plate 23 is fixedly connected to the movable end of the damper 22. The connecting plate 23 connects a sleeve shaft 25 and a spring 24. A spring 24 is fixedly connected between the connecting plate 23 and the damper 22. The spring 24 is a high-strength coil spring capable of withstanding significant pressure and impact. A sleeve 25, which fits over the wheel axle 1, is fixedly connected to the connecting plate 23. An adjustment assembly 26 is provided on the damper 22. Bolts 29 are detachably connected to the mounting plate 21. The hexagonal ends of the bolts 29 facilitate securement to the vehicle frame using tools. Before using the electric scooter, the mounting plate 21 and its attached structure are placed under the vehicle frame. The sleeve 25 is inserted into the wheel axle 1, and the mounting plate 21 is then secured to the vehicle frame using bolts 29. The adjustment assembly 26 is then adjusted to the appropriate damping range to meet different damping requirements. When the electric scooter travels over uneven surfaces, the impact force on the wheel is transmitted to the spring 24 and damper 22. The spring 24 is first compressed, absorbing some of the impact force. The damper 22 then slows the spring's rebound speed by controlling the flow of hydraulic oil, achieving the desired damping effect. This reduces the impact of road vibration on the rider, resulting in a smoother ride and significantly less jolting, making the rider more comfortable and less fatigued. This reduces impact forces on the wheels, minimizing damage to the scooter's frame, motor, battery, and other components. This reduces wear and tear, extending the vehicle's service life. It also improves the scooter's stability during driving, reducing the risk of loss of control due to bumpy roads and enhancing driving safety. It also reduces vibration-related malfunctions and improves the scooter's reliability. This improved stability makes it easier for the rider to control the scooter, reducing the risk of rollovers and falls. It's compatible with various electric scooter models, making installation and replacement easy.

[0025] Considering that different users have different requirements for shock absorption, it is necessary to adjust the shock absorption range of the shock absorption component 2 to meet different personalized needs. Figure 1-Figure 3The adjustment assembly 26 includes a rotating shaft 261 rotatably mounted on the damper 22. The rotating shaft 261 is used to drive a sealing plate 262. The end of the rotating shaft 261 is fixedly connected to multiple sealing plates 262 that rotate within the damper 22. The sealing plates 262 are used to block the damping holes within the damper 22 and control the flow rate of the hydraulic oil therein. The number of sealing plates 262 is the same as the number of damping holes within the damper 22. The sealing plates 262 are larger than the damping holes to ensure that the damping holes can be completely sealed. The gap between the sealing plates 262 is greater than or equal to the width of the damping holes, ensuring that the maximum flow rate is not restricted when adjusting the flow rate of the hydraulic oil therein. A hydraulic damper typically has one or more damping holes inside. After the shock absorbing assembly 2 is installed, the rotating shaft 261 is rotated to cause the sealing plates 262 to adjust the outlet size of the damping holes within the damper 22. By changing the size of the damping holes, the flow rate of the hydraulic oil is controlled, thereby adjusting the magnitude of the damping force. By adjusting the damping coefficient, the hydraulic damper's ability to suppress the vibration of spring 24 can be altered, thereby controlling the spring's damping strength. This allows for adjustment of the damping range to meet individual needs, allowing riders of varying weights to find the most suitable damping effect for their individual needs. It can also accommodate different riding styles, allowing everyone to find the riding experience that best suits them.

[0026] Considering that the magnitude of the adjustment cannot be well controlled when adjusting the damping force of the damper 22, it is necessary to be able to intuitively and easily know the magnitude of the adjusted damping force. Figure 1-Figure 3 The damper 22 is provided with scale lines 27 on its surface, and the values ​​on these lines correspond to the size of the damping orifice. An indicator bar 271 is fixedly attached to the damper 22, located above the scale lines 27. To adjust the damping range, the damping orifice is resized by rotating the shaft 261. Simply observing the position of the indicator bar 271 on the scale lines 27 accurately determines the damping orifice size, providing a simple and intuitive way to determine whether the adjusted damping range is accurate.

[0027] Example 2

[0028] On the basis of Example 1, considering that the installation of the shock absorbing assembly 2 will cause compression to the mounting plate 21 and the sleeve shaft 25, which may easily cause damage to them and affect their service life, it is necessary to reduce the direct compression caused to them, see Figure 1-Figure 3 The mounting plate 21 is provided with a rubber pad 28, and the ends of the sleeve shaft 25 are fixedly connected with rubber sleeves 251. During installation, the rubber pad 28 and the rubber sleeve 251 can directly avoid direct contact with each other, and the material properties can effectively reduce the extrusion wear, thereby reducing damage and extending the service life.

[0029] Considering that the size of the outlet of the damping hole needs to be adjusted to control the flow rate of the hydraulic oil inside it when adjusting the shock absorption range, and the sealing plate 262 may have gaps in its sealing, affecting the accuracy of the adjustment, it is necessary to improve the sealing effect of the sealing plate 262, see Figure 1-Figure 3 Sealing plate 262 is fixedly connected to a sealing gasket 263 made of corrosion-resistant rubber. Sealing gasket 263 is located in front of the damping orifice and conforms to its surface. When sealing plate 262 adjusts the position of sealing gasket 263 to adjust the size of the damping orifice, the material properties of sealing gasket 263 enhance the sealing effect of the damping orifice, ensuring the accurate adjustment range and reducing repeated adjustments.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
