Description

Technical Field

[0001] This utility model relates to the field of scooters, and more particularly to a steering damping mechanism suitable for scooters and a scooter. Background Technology

[0002] In the realm of short-distance commuting and recreational sports, scooters, with their core advantages of portability and flexibility, have become an essential tool for daily travel and entertainment. As users' demands for stability increase, scooter wheel designs have gradually evolved from traditional two-wheeled to multi-wheeled models. Currently, some scooters on the market feature three or four wheels. These multi-wheeled scooters effectively reduce the risk of tipping during riding by increasing the contact points with the ground, making them particularly suitable for children, teenagers, and the elderly with weaker balance. They have captured a significant market share in family use and leisure scenarios.

[0003] In the structural design of multi-wheeled scooters, the layout of two front wheels is quite common. Whether it is a three-wheeled scooter (two front wheels and one rear wheel) or a four-wheeled scooter (two front wheels and two rear wheels), the setting of two front wheels can significantly improve the vehicle's adaptability to the road surface, reduce the bumpy feeling when a single front wheel encounters an obstacle, and provide more stable support during turning, avoiding the control deviation caused by uneven force on one side. Therefore, it has become one of the mainstream directions in the design of multi-wheeled scooters.

[0004] Among existing scooter technologies, the "Front Two-Wheel Shock-Absorbing Scooter" patent application number 201310126649.3 is a representative design. This design includes core components such as the frame, shock-absorbing axles, pedals, handlebars, handlebar connectors, two front wheels, and a rear wheel cover. It attempts to mitigate road vibrations by installing shock-absorbing axles on the front wheels. However, in actual use, it has been found that the shock-absorbing structure of this design only provides simple buffering for localized vibrations of the front wheels and does not form a comprehensive shock-absorbing system that runs through the entire frame. Furthermore, the elastic coefficient and travel design of the shock-absorbing axles fail to match the vibration intensity of different road surfaces. When traversing uneven surfaces such as gravel roads and speed bumps, vibrations are directly transmitted through the frame to the pedals and handlebars, causing the user's buttocks and hands to feel noticeable bumps. Prolonged use can easily lead to muscle fatigue, especially in scenarios involving carrying cargo or children, where the comfort deficiencies are even more pronounced. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a steering damping mechanism and scooter suitable for scooters that can effectively reduce the vibration experienced by the human body.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is a steering damping mechanism suitable for scooters, including a steering rod and two wheels. The steering rod is characterized by having a steering rod fixing seat sleeved on its outer side. Two upper rocker arm assemblies and two lower rocker arm assemblies are arranged between the steering rod fixing seat and the wheel axles of the two wheels. The upper rocker arm assembly includes a first upper rocker arm and a second upper rocker arm, and the lower rocker arm assembly includes a first lower rocker arm and a second lower rocker arm. The first upper rocker arm is connected to the lower end of a first connecting rod, and the second upper rocker arm is connected to the lower end of a second connecting rod. The upper end of the first connecting rod is connected to one end of a first swing arm, and the upper end of the second connecting rod is connected to one end of a second swing arm. The middle parts of the first and second swing arms are axially connected to the steering rod fixing seat, and the other ends of the first and second swing arms are respectively connected to the two ends of a damping spring.

[0014] A scooter, including the aforementioned steering damping mechanism suitable for a scooter.

[0015] This invention establishes a steering rod fixing seat on the outside of the steering rod, which, together with the upper rocker arm assembly, lower rocker arm assembly, connecting rod, swing arm, and shock-absorbing spring, forms a linkage structure, creating an integrated shock absorption system covering the steering system and wheels. When the scooter encounters bumpy roads, the vibrations experienced by the wheels are transmitted to the connecting rod through the upper and lower rocker arm assemblies, causing the swing arm to rotate around the steering rod fixing seat as its axis. This triggers the shock-absorbing spring to extend and retract, effectively solving the problem of significant vibration to the rider. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] As is well known, the shock absorption of scooters mainly relies on shock-absorbing springs. These springs prevent the force from being directly transmitted to the scooter user, thus achieving a shock absorption effect. This invention develops a steering shock absorption mechanism suitable for scooters and a scooter in general.

[0022] like Figures 1-4As shown, a steering damping mechanism suitable for a scooter includes a steering rod 1 and two wheels 2. A steering rod fixing seat 3 is sleeved on the outer side of the steering rod 1. Two upper rocker arm assemblies and two lower rocker arm assemblies are arranged between the steering rod fixing seat 3 and the wheel axles of the two wheels 2. The upper rocker arm assembly includes a first upper rocker arm 7 and a second upper rocker arm 8. The lower rocker arm assembly includes a first lower rocker arm 9 and a second lower rocker arm 10. The first upper rocker arm 7 is connected to the lower end of a first connecting rod 11. The second upper rocker arm 8 is connected to the lower end of a second connecting rod 12. The upper end of the first connecting rod 11 is connected to one end of a first swing arm 13. The upper end of the second connecting rod 12 is connected to one end of a second swing arm 14. The middle parts of the first swing arm 13 and the second swing arm 14 are axially connected to the steering rod fixing seat 3. The other ends of the first swing arm 13 and the second swing arm 14 are respectively connected to the two ends of a damping spring 15.

[0023] When the wheel 2 on one side of the first upper rocker arm 7 is bumped, the first upper rocker arm 7 and the first lower rocker arm 9 are lifted. After the first upper rocker arm 7 is lifted, the first connecting rod 11 is lifted. Under the action of the first connecting rod 11, one end of the first swing arm 13 is lifted and the other end is pressed down. After the first swing arm 13 is pressed down, it compresses the shock-absorbing spring 15. When the wheel 2 on one side of the second upper rocker arm 8 is bumped, a similar process will occur, and the second swing arm 14 will compress the shock-absorbing spring 15. The shock-absorbing spring 15 will provide a buffering force after being compressed, thereby greatly reducing the vibration felt by the human body. When the scooter encounters a bumpy road, the vibration felt by the wheel 2 will be transmitted to the first connecting rod 11 and the second connecting rod 12 through the upper rocker arm assembly and the lower rocker arm assembly, causing the first swing arm 13 and the second swing arm 14 to rotate around the steering rod fixing seat 3 as the axis, thereby triggering the shock-absorbing spring 15 to extend and buffer. It effectively solves the problem of significant shock to the human body. At the same time, the symmetrical layout of the upper rocker arm assembly, the lower rocker arm assembly, the first swing arm 13, and the second swing arm 14 ensures that the wheel 2 is subjected to balanced force during the shock absorption process.

[0024] The first upper rocker arm 7 and the first lower rocker arm 9 are connected by the first connecting base plate 16 and can be raised or lowered synchronously. The second upper rocker arm 8 and the second lower rocker arm 10 are connected by the second connecting base plate 17 and can be raised or lowered synchronously. The upper rocker arm assembly and the lower rocker arm assembly on the same side are connected by the first connecting base plate 16 and the second connecting base plate 17 to form a synchronous motion unit, ensuring that the upper rocker arm assembly and the lower rocker arm assembly can be raised or lowered synchronously when the wheel 2 is subjected to vibration.

[0025] A first connecting base 18 is provided between the first upper rocker arm 7 and the first lower rocker arm 9. The first connecting base 18 drives the first upper rocker arm 7 and the first lower rocker arm 9 to tilt up or down synchronously. A second connecting base 19 is provided between the second upper rocker arm 8 and the second lower rocker arm 10. The second connecting base 19 drives the second upper rocker arm 8 and the second lower rocker arm 10 to tilt up or down synchronously. The first connecting base 18 and the second connecting base 19 replace the first connecting substrate 16 and the second connecting substrate 17. The rigid connection of the first connecting base 18 and the second connecting base 19 drives the upper rocker arm assembly and the lower rocker arm assembly on the same side to move synchronously.

[0026] The first connecting base 18 includes a first vertical connecting member 20 and a first horizontal connecting member 21, and the second connecting base 19 includes a second vertical connecting member 22 and a second horizontal connecting member 23. The first horizontal connecting member 21 and the second horizontal connecting member 23 are connected to the corresponding wheels 2. The upper and lower ends of the first vertical connecting member 20 are respectively connected to the first upper rocker arm 7 and the first lower rocker arm 9, and the upper and lower ends of the second vertical connecting member 22 are respectively connected to the second upper rocker arm 8 and the second lower rocker arm 10. The first vertical connecting member 20 and the second vertical connecting member 22 ensure the continuous force transmission between the upper rocker arm assembly and the lower rocker arm assembly, while the first horizontal connecting member 21 and the second horizontal connecting member 23 stably support the vibration of the wheels 2.

[0027] The steering lever is connected to the first lateral connector 21 via the first steering connector 24, and to the second lateral connector 23 via the second steering connector 25. When the user operates the steering lever 1, the steering force can be directly transmitted to the first lateral connector 21 and the second lateral connector 23 through the first steering connector 24 and the second steering connector 25. The first lateral connector 21 and the second lateral connector 23 are directly connected to the wheel 2, which can quickly drive the wheel 2 to turn synchronously.

[0028] The first swing arm 13 and the second swing arm 14 are both pivotally connected to the steering rod fixing seat 3 at their midpoints, and the first swing arm 13 and the second swing arm 14 rotate around the steering rod fixing seat 3. The pivotal connection of the first swing arm 13 and the second swing arm 14 to the steering rod fixing seat 3 and their rotation around it provides a stable rotation center for the movement of the first swing arm 13 and the second swing arm 14.

[0029] Both the first upper rocker arm 7 and the first lower rocker arm 9 include a first rocker arm 26, a second rocker arm 27, a first reinforcing rod 28, and a first connecting rod 29. Both the second upper rocker arm 8 and the second lower rocker arm 10 include a third rocker arm 30, a fourth rocker arm 31, a second reinforcing rod 32, and a second connecting rod 33. The first reinforcing rod 28 and the first connecting rod 29 are positioned between the first rocker arm 26 and the second rocker arm 27, while the second reinforcing rod 32 and the second connecting rod 33 are positioned between the third rocker arm 30 and the fourth rocker arm 31. The addition of the first reinforcing rod 28, the second reinforcing rod 32, the first connecting rod 29, and the second connecting rod 33 to the upper and lower rocker arm assemblies creates a multi-rod collaborative frame structure. The first reinforcing rod 28 and the second reinforcing rod 32 can enhance the bending and deformation resistance of the upper rocker arm assembly and the lower rocker arm assembly, avoid the breakage or deformation of the upper rocker arm assembly and the lower rocker arm assembly caused by long-term vibration, and improve the overall strength of the mechanism; the first connecting rod 29 and the second connecting rod 33 connect the first rocker arm 26 and the second rocker arm 27, and the third rocker arm 30 and the fourth rocker arm 31 into a stable whole.

[0030] A first ring 34 is provided on the first connecting rod 29, and the first ring 34 is fitted onto both ends of the first vertical connecting member 20. A second ring 35 is provided on the second connecting rod 33, and the second ring 35 is fitted onto both ends of the second vertical connecting member 22. The sliding connection design of the first ring 34 and the second ring 35 allows the first connecting rod 29 and the second connecting rod 33 to be directionally adjusted along the first vertical connecting member 20 and the second vertical connecting member 22 when moving with the upper rocker arm assembly.

[0031] A scooter includes a steering damping mechanism as described above. The integrated steering damping mechanism gives the scooter both efficient shock absorption and stable steering. Compared to existing scooters with poor shock absorption, this integrated mechanism effectively blocks the transmission of road vibrations, significantly reducing the rider's sensation of shock and improving riding comfort. Simultaneously, the symmetrical layout and coordinated design of the mechanism ensure stability during riding and steering, making it suitable for various groups, including children and the elderly.

[0032] The foregoing has provided a detailed description of the steering and shock absorption mechanism for scooters and the scooter itself, as provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand this utility model and its core concepts. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
